Abstract
It is desired to realize designing of a light, compact body and improved brushing effect and massage effect without causing any inconvenience, and to prevent the tip of a brush formed by a bristle bundle from remaining curled.
A flexible diaphragm 13 which is displaced together with a reciprocative base 10 of a brush 9 is provided between a body space 2 and a brush guide passage 6. An air introduction hole 15 having a valve 14 which opens only to the inside is formed in a midpoint of the brush guide passage 6. When the diaphragm 13 is displaced toward the body space 2 with the reciprocation motion of the base 10, air is introduced through the air introduction hole 15 into the brush guide passage 6, which is now under negative pressure. When the diaphragm 13 is displaced toward the brush guide passage 6, the introduced air is compressed and is ejected from the opening 6 a at the tip. Thus, the body can be designed lightly and compactly, and the brushing effect and the massage effect are improved without causing inconvenience.
Description
- The present invention relates to an electric toothbrush having a base in which brush formed by a bristle bundle is implanted and which is reciprocated so that the tip of the brush moves in and out of an opening directed to the mouth.
- There are various forms of electric toothbrushes. In one of such electric toothbrushes, in a casing having a brush guide passage extending from a body space in which a reciprocating motion source is disposed to one end side, a base in which a brush formed by a bristle bundle directed to the tip of the brush guide passage is implanted is reciprocated by predetermined strokes toward the brush guide passage by the reciprocating motion source so that the tip of the brush moves in and out of an opening formed at the end of the brush guide passage having a bent portion. With the brush moving in and out of the opening directed to the mouth, teeth are brushed and also the gums can be massaged (see Patent Document 1).
- The electric toothbrush disclosed in
Patent Document 1 is provided with a cleaning fluid tank storing a cleaning fluid. The cleaning fluid in the cleaning fluid tank is discharged by an electric or manual pump and is ejected from the opening, through which the brush moves in and out, thereby increasing the brushing effect and the massage effect. - In order to eject cleaning fluid from the opening which is directed to the mouth and through which the brush moves in and out, the electric toothbrush of
Patent Document 1 needs a pump for discharging cleaning fluid in the cleaning fluid tank in addition to the reciprocating motion source for reciprocating the base of the brush. Consequently, the electric toothbrush has a problem that the body is heavy and large. - When the electric toothbrush is used in a washroom, a bathroom or the like, the cleaning fluid ejected into the mouth can be discharged into its drainage system such as a washstand. But if the electric toothbrush is used in a place where there is no drainage system, such as in a living room, it is inconvenient for the user since he/she cannot discharge the cleaning fluid from the mouth.
- Further, when the electric toothbrush is repeatedly used, due to the influence of the bent portion in the brush guide passage, the tip of the brush formed by a bristle bundle remains curled. A problem occurs that the brushing effect and the massage effect deteriorate.
- An object of the present invention is therefore to realize designing of a light, compact body and improved brushing effect and massage effect without causing any inconvenience, and to prevent the tip of a brush formed by a bristle bundle from being curled.
- To solve the problems, the present invention provides an electric toothbrush comprising a casing having therein a brush guide passage extending from one end side of a body space, a reciprocating motion source mounted in the body space, and a base mounted in the casing and coupled to the reciprocating motion source, the base being planted with a brush formed by a bristle bundle and extending toward a tip of the brush guide passage, the base being reciprocated toward the brush guide passage so that the tip of the brush moves in and out of an opening formed at the tip of the brush guide passage, characterized in that a flexible diaphragm which is displaced together with the reciprocative base is provided between the body space and the brush guide passage, and that an air introduction hole provided with a valve which opens only to the inside is formed in a midpoint of the brush guide passage, whereby when the diaphragm is displaced toward the body space with the reciprocating motion of the base, air is introduced into the brush guide passage, which is now under negative pressure, and when the diaphragm is displaced toward the brush guide passage, air introduced into the brush guide passage is compressed, and the compressed air is injected from the opening formed at the tip of the brush guide passage.
- That is, the flexible diaphragm which is displaced together with the reciprocative base is provided between the body space and the brush guide passage. An air introduction hole provided with a valve which opens only to the inside is formed in a midpoint of the brush guide passage. When the diaphragm is displaced toward the body space with the reciprocating motion of the base, air is introduced into the brush guide passage, which is now under negative pressure, through the air introduction hole. When the diaphragm is displaced toward the brush guide passage, the air introduced into the brush guide passage is compressed, and the compressed air is injected through the opening formed at the tip of the brush guide passage. With this arrangement, air can be injected into the mouth without providing a separate pump. The body can be designed lightly and compactly. Even when the electric toothbrush is used in a place where there is no drainage system, there is no inconvenience. The brushing effect and the massage effect can be increased.
- The electric toothbrush may further comprise a cleaning fluid tank mounted in the casing and storing a cleaning fluid, and means for discharging the cleaning fluid in the cleaning fluid tank into the brush guide passage. With this arrangement, the cleaning fluid discharged into the brush guide passage is injected together with air from the opening formed at the tip of the brush guide passage, thereby enabling the brushing effect and the massage effect to be further increased.
- By discharging the cleaning fluid into a portion of the brush guide passage near its tip, the force of injecting the cleaning fluid from the opening formed at the tip of the brush guide passage can be enhanced.
- The means for discharging the cleaning fluid in the cleaning fluid tank may be configured to discharge the cleaning fluid in the cleaning fluid tank by introducing air in the brush guide passage, which is compressed when the diaphragm is displaced toward the brush guide passage, into the cleaning fluid tank. With this arrangement, the cleaning fluid in the cleaning fluid tank can be ejected without providing a separate pump.
- In another arrangement, the body space is hermetically closed, an air introduction hole provided with a valve which opens only to the inside is formed in a wall forming the body space, and the means for discharging the cleaning fluid in the cleaning fluid tank discharges the cleaning fluid in the cleaning fluid tank by introducing air from the air introduction hole to the body space, which is under negative pressure, when the diaphragm is displaced toward the brush guide passage, and by compressing air introduced into the body space and introducing the compressed air into the cleaning fluid tank when the diaphragm is displaced toward the body space. cleaning fluid tank. With the arrangement too, the cleaning fluid in the cleaning fluid tank can be ejected without providing a separate pump.
- The invention also provides an electric toothbrush comprising a brush formed by a bristle bundle and reciprocated by a predetermined stroke along a brush guide passage having a bent portion so that the tip of the brush moves in and out of an opening formed at the tip of the brush guide passage, characterized in that a straight portion or a reverse bent portion which is bent in the direction opposite to the bent portion is provided on the tip side of the bent portion in the brush guide passage.
- Specifically, by forming a straight portion or a reverse bent portion which is bent in the direction opposite to the bent portion on the tip side of the bent portion in the brush guide passage, curling of the tip of the brush formed in the bent portion is corrected by the straight portion or the reverse bent portion formed at the tip of the bent portion, so that the tip of the brush does not remain curled.
- By setting the straight portion or the inverse bent portion in the brush guide passage to a length equal to or larger than the stroke of the brush, a sufficient curl correcting effect can be obtained.
- By forming a cleaning hole for cleaning the brush in the passage in a midpoint of the brush guide passage, the base portion of the brush in the brush guide passage can be easily washed by injecting tap water or the like from the cleaning hole.
- In the electric toothbrush of the invention, a flexible diaphragm which is displaced together with the reciprocative base is provided between the body space and the brush guide passage.

FIG. 1 toFIGS. 4A and 4B show the first embodiment. In the electric toothbrush of the first embodiment, as shown inFIG. 1 , amotor 3 as a reciprocating motion source, acrankshaft 4 provided for the output shaft of the motor, and a cleaningfluid tank 5 storing cleaning fluid are disposed in abody space 2 of acasing 1. Acylindrical member 8 is attached to thecasing 1. Thecylindrical member 8 includes abrush guide passage 6 extending from one end of thebody space 2 and having anopening 6 a at its tip and a cleaningfluid passage 7 that extends along thebrush guide passage 6 and opens to thebrush guide passage 6 near its tip. In thebrush guide passage 6, a base 10 in which abrush 9 formed by a bristle bundle directed to the tip side of thebrush guide passage 6 is implanted is coupled via acoupling member 12 to anarm member 11 attached to thecrankshaft 4. Therefore, by rotating themotor 3, thebase 10 reciprocates in a predetermined stroke in the direction of thebrush guide passage 6, and the tip of thebrush 9 moves in and out of theopening 6 a. - To the
coupling member 12, aflexible diaphragm 13 separating between thebody space 2 and thebrush guide passage 6 is attached. Anair introduction hole 15 attached with a tongue-shapedvalve 14 which opens only to the inside is formed in a midpoint of thebrush guide passage 6. The outer periphery of thediaphragm 13 is attached to the inner wall of thecasing 1 and a mountingwall 16 of the cleaningfluid tank 5 extending radially inwardly into thebody space 2. - Therefore, as shown in
FIG. 1 , when thereciprocating base 10 moves backward, thediaphragm 13 is displaced toward thebody space 2, and air is introduced from theair introduction hole 15 into thebrush guide passage 6 because thebrush guide passage 6 is now under negative pressure. As shown inFIG. 2 , when the base 10 moves forward, thediaphragm 13 is displaced toward thebrush guide passage 6, the air introduced into thebrush guide passage 6 is compressed, and the compressed air is ejected through theopening 6 a. - As shown in
FIG. 3 , a flexibleinner bag 17 is housed in the cleaningfluid tank 5 and is filled with cleaning fluid. The mouth of theinner bag 17 is connected to the cleaningfluid passage 7 of thecylindrical member 8 via afluid hole 18 formed in the mountingwall 16. In the mountingwall 16, anair hole 19 for passing air to the side of thediaphragm 13 facing thebrush guide passage 6 is formed. Theair hole 19 communicates with the interior of the cleaningfluid tank 5 outside theinner bag 17. - Therefore, as shown in
FIG. 2 , when thediaphragm 13 is displaced toward thebrush guide passage 6 and air introduced into thebrush guide passage 6 is compressed, compressed air is introduced into the cleaningfluid tank 5 via theair hole 19, and the cleaning fluid in theinner bag 17 passes through thefluid hole 18 and the cleaningfluid passage 7 and is discharged into a portion of thebrush guide passage 6 near its tip. The discharged cleaning fluid is ejected together with compressed air through theopening 6 a. - As shown in
FIG. 4A , thebrush guide passage 6 of thecylindrical member 8 has abent portion 6 b and, at its tip side, a straight portion 6 c. The length of the straight portion 6 c is substantially equal to the stroke of thebrush 9. In midpoints of thebrush guide passage 6, two ellipsoidal cleaning holes 24 are formed through which e.g. tap water is injected to clean thebrush 9. -
FIG. 4B shows a modifiedbrush guide passage 6 of thecylindrical member 8. The modifiedbrush guide passage 6 has a reversebent portion 6 d which is bent in the direction opposite to abent portion 6 b similar to that of the embodiment at the tip side of abent portion 6 b. The length of the reversebent portion 6 d is substantially equal to the stroke of thebrush 9. -
FIGS. 5 to 7 show the second embodiment. The basic configuration of an electric toothbrush of the second embodiment is the same as that of the first embodiment, but the following points are different. As shown inFIG. 5 , in place of theair hole 19 in the mountingwall 16, anair introduction hole 21 attached with a tongue-shapedvalve 20 which opens only to the inside is formed in the wall of thecasing 1 forming thebody space 2. Although not shown, the rear end side of thebody space 2 is hermetically closed. As shown inFIG. 7 , the cleaningfluid tank 5 is provided with afluid supply pipe 22 whose tip opens near the bottom of the fluid and which is continued to thefluid hole 18 in the mountingwall 16. The interior of the cleaningfluid tank 5 communicates with thebody space 2 via anair hole 23. Otherwise, this embodiment is the same as the first embodiment. - Therefore, in this embodiment, as shown in
FIG. 6 , when the base 10 moves forward and thediaphragm 13 is displaced toward thebrush guide passage 6, air is introduced from theair introduction hole 21 into thebody space 2, which is now under negative pressure. As shown inFIG. 5 , when the base 10 moves backward and thediaphragm 13 is displaced toward thebody space 2, the introduced air is compressed, and the compressed air is introduced into the cleaningfluid tank 5 via theair hole 23. The interior of the cleaningfluid tank 5 is thus pressurized, and cleaning fluid therein is discharged via thefluid hole 18 and the cleaningfluid passage 7 into a portion of thebrush guide passage 6 near its tip. The discharged cleaning fluid is ejected from theopening 6 a together with the compressed air in a manner similar to the first embodiment. - Although in the embodiments, a motor provided with a crankshaft on its output shaft is used as the reciprocating motion source of the base, the reciprocating motion source is not limited to that in the embodiments. An arbitrary drive source for giving the reciprocating motion to the base can be employed.
- Although the casing in which the body space is formed and the cylindrical member having the brush guide passage are separate members in the embodiments, the cylindrical member may be integrally formed with the casing. The shapes of the casing and the cylindrical member are not limited to those of the embodiments.
