Description

INTEGRAL DENTAL BRUSH

TECHNICAL FIELD OF THE INVENTION

The present invention relates to the technical field of Dentistry, specifically in oral hygiene, since it provides a toothbrush with integrated dentifrice, which has the versatility of being able to exchange a toothpaste cartridge; In addition, the brush can have only fixed bristles, or the combination of fixed and rotating bristles. Said brush can be operated manually, becoming a normal vibrator, or electrically and is transformed into a brush with electronic vibration, to give a better cleaning and massage to the dental gums.

BACKGROUND OF THE INVENTION

At present, the brushes that have toothpaste integrated in their handle and that are refillable have the disadvantage that they do not have a replacement toothpaste cartridge of their preference, as well as a disposable cartridge, where both consist of the same Brush handle and toothpaste tanks (MX patents 147198, MX 169057 and MX 167275).

Although the utility model document MX 594 already describes a toothbrush with integrated dentifrice, comprising a spare disposable male cartridge, which goes inside the handle of said brush; However, it has the problem that to be refilled, it has to be done through a special process since the manufacture of said cartridge. This brush is also not electric and does not have a replacement cartridge with paste of your choice. Another disadvantage of conventional brushes with integrated toothpaste is that they do not have the versatility of having their components replaced, such as the motor, handle, head, etc., so that if any of these elements deteriorates, It has to be completely removed.

As for known electric toothbrushes, these are generally driven by small motors that go inside the handle of the brushes and are connected by mechanisms that provide movement, in at least one direction and in at least a portion, of the bristles located in the head, as described in the patent application documents MX PA / a / 2000/1338 and PA / a / 2001/6566. However, these brushes do not have integrated toothpaste and much less have refillable cartridges.

Therefore, with the purpose of eliminating all the aforementioned drawbacks, a new toothbrush with integrated toothpaste was developed, which is rechargeable and can be manual or electric; So it has many advantages compared to toothbrushes with integrated toothpaste and those that are only electric; which I intend to protect in this application and described in detail below.

Figure 13 is a conventional perspective view of the toothbrush with toothpaste integrated with the electric motor and the power source, integrated.

With reference to said figures, the integrated toothpaste toothbrush of the present invention consists of:

A hollow head 1, which may have, in its upper part, only fixed bristles 2, or the combination of fixed and rotating bristles 3, the latter are on a disk-shaped base 4, which rotates on a small axis 5 , said base 4 can be secured by a washer 6 held by a bolt (not shown) that crosses said axis 5, however, it can be any other means of attachment. In the lower internal part of the hollow head 1 there is a cavity 7 that receives the other end of the small axis 5, and in the upper part there is a hole 8 that allows the toothpaste to pass outside the brush; finally, said head 1 has an internal thread 9 in its lateral opening 10, to allow the connection of a neck 11.

The neck 11 is constituted of an elongated tube 12 that is introduced to the hollow head 1, through the lateral opening 10, which has a hole 13 in such a position, so that it coincides with the hole 8 and thus form an outlet continuous of the toothpaste; This tube 12 has one end closed and another open with an external thread 14, to hold said tube 12 to the head 1 and, in addition, it positions the hole 13 to make it coincide with the hole 8. This neck 11 has a conical extension 15 with an external striated portion 16 to provide grip support when a new cartridge is changed or the hollow head 1 is rotated to pass the paste out of the brush. A internal roscα 17 is located at the open end of neck 11, to attach it to a toothpaste container 18.

The dentifrice container 18 consists of a cylindrical body 19, which has an externally threaded neck 20 to couple the container 18 with the internal thread 17 of the conical section 15. At the other end of the cylindrical body 19 a clasp 21 is located externally. to hold a spoon 22 for cleaning the tongue; It also has a 16 ribbed for better grip; finally, this cylindrical body has a larger opening 23 opposite the threaded neck 20, to receive a toothpaste delivery mechanism 24.

The pulp supply mechanism 24 is integrated with a hollow knob 25 at its rear, but in front of it its diameter is slightly reduced, thus forming a kind of base 50 whose diameter must be exactly equal to the diameter of the opening 23 of the cylindrical body 19, such that said base 50 is inserted through the opening 23 tightly, so that there is better coupling between these two pieces; in the central part of the base 50 a screw 26 is extended that runs internally and longitudinally to the cylindrical body 19, and in said screw 26 a smooth platform 27 is moved, like a piston, which makes contact with the toothpaste and goes moving towards the hollow head 1 of the toothbrush. At the end of the hollow part 28 of the knob 25 there is an internal thread 29 to receive an external thread 30 of a cover 31, the latter has in the center a post 32 where a reel with dental floss 33 is inserted, the which is inside the cavity 28 once the brush is assembled.

The way in which the paste moves is as follows, to knob 25 two or three turns are made counterclockwise, in such a way that part of the base 50 moves out of the cylindrical body 19, adjusting the amount of paste that is required; but the platform 27 does not move, and then it is pushed to the knob 25 until the part of the base 50 that left, is completely introduced to the body of the cylinder 19 and that is when the platform 27 moves further into said cylinder 19 and thus drives the toothpaste towards the hollow head 1 of the brush, which leaves where the bristles are, for which, the holes 8 and 13 must be in the exact position, one above the other, respectively, so that there is a continuous exit of the toothpaste, so it is necessary that in the hollow head 1 and the neck 11, there is a sign or mark, so that it is indicated when the holes are in the correct position. That is, it is preferred that when the signals coincide is that the holes are in the correct position and to close the flow it is enough to turn the hollow head 1 and therefore the signals will not coincide either.

In this way we obtain a brush for oral cleaning, with integrated and rechargeable toothpaste, since it is enough to refill the paste container 18 with the desired toothpaste, or even, said container 18 can be replaced with a new one, if This is desired. In light of what has been described so far, the brush is manually operated, and when it has only fixed bristles 2, its function is like that of any normal brush, but when it has the combination of fixed and rotating bristles 2, the latter will rotate by The friction on the gums and teeth. However, a conventional small motor 39 can be added to said brush as one of the embodiments of the present invention, which I describe below (see figure 6).

In this case, modifications are made to the small engine 39, one of which is that its arrow is extended by an extension that it joins, slightly to one side of the center, a cone 38, to which a second extension diametrically opposite the first extension is solid on the other side, to hold a cone 37. Thus, the arrangement of the cones 38 and 37 is in the form of "Z", (see figures 6, 7, 10, and 1 1), so that when the motor rotates its arrow, the extensions and cones also rotate, but not on its own axis and thus They will provide more vibration to the brush. The motor is placed in a housing 40 with external thread 52 at the end where the cones 37 and 38 are, so that it is connected with the internal thread 29 of the hollow knob 25, of the paste supply 24. At the other end, the housing 40 carries an internal thread 54, to receive the thread 53 of another housing 51 containing a battery 45 that provides power to the motor 39, by means of a positive contact 41 and a negative 49 of said motor 39, which is joined by means of a cable 43. It is evident that to place the motor 39, the cover 31 and the spool of thread 33 must be removed, so that the cone 37 which is housed in the area 28 of the knob 25.

However, the electric power can also be provided by a battery eliminator (not illustrated), for which, a cover 56 with a received 55 is required, in which the eliminator contact (not illustrated) is connected; The positive contacts 41 and negative 49 are connected to said receiver 55, by means of cables 44 and 47, respectively (see Figure 1 1).

Therefore, we can now have an electric toothbrush, which also, having the aforementioned characteristics and variants, also has vibration, which is provided by the motor 39, with which, in addition to the oral cleaning, massage is provided to the gums.

Another of the variants of the brush is to make the rotating bristles 3 have movement, for which, a long and thin shaft 36 is attached to the cone 37, which internally crosses the base 50 and the screw 26, the toothpaste container 18 and the neck 11, until it reaches the hollow head 1, where it joins a small gear 35, which makes contact with another gear 34 fixed to the small axis 5 (see figure 7). In this way, when the motor 39 rotates its arrow, it will also make the thin shaft 36 rotate and this in turn will rotate the small gear 35 and this in turn will do the same with the gear 34 and this will rotate the small axis 5, to which the circular base 6 is attached where the rotating bristles 3 are.

Finally, we can now have an electric toothbrush, but with rotating bristles 3 in motion, which will further facilitate oral cleaning, without the need to make circular movement to the gums, just as conventional toothbrushes are made, since said rotating bristles will handle such circular movement.

To fill the toothpaste container 18 with toothpaste 18, the paste delivery mechanism 24 must be removed and the neck of the commercial paste tube must be placed in the inlet 23 of the cylindrical body and the paste emptied until said cylindrical body is filled.

All these mentioned characteristics, we do not find them in the brushes with integrated toothpaste, nor in those that are only electric, conventional.
