Description

TECHNICAL FIELD

The utility model is an adjustable toothbrush realized through four control modes, and belongs to the technical field of daily necessities. Background technique

The common feature of toothbrushes circulating in the market, whether wavy or crescent, is that the shape is fixed, but the shape of the teeth is diverse, so it is impossible to completely and completely clean each part of the tooth, especially It is the uneven surface of the inside and root of the tooth, as well as the molar. In addition, a small amount of toothpaste will fall every time you brush your teeth, causing unnecessary waste and difficult to clean.

Summary of the invention

The utility model is aimed at the uneven surface of the roots and molars of the tooth which cannot be thoroughly and thoroughly cleaned by the existing toothbrush.

As well as the disadvantage that there will be a little toothpaste falling every time you brush your teeth, a new concept of changing the shape of the brush head by manual adjustment is proposed. Controlled adjustable toothbrush to achieve-

1. Fold-control adjustable toothbrush consists of movable brush head, fixed brush head, shaft, shaft, brush handle and folding control head. The characteristic of the brush is that the front half of the fixed brush head has a through hole in the same direction as the bristles, and the movable brush head is placed therein and is combined with the fixed brush head through the shaft (the brush head part of the three adjustable toothbrushes in the back This is the same and will not be described again). The rear half of the fixed brush head has a through hole in the same direction as the brush handle, and a folding control head connected to the brush handle is located therein, and is combined with the outer wall of the through hole through a shaft. The end of the movable brush head and the top end of the folding control head are interlocked, and the fastening method may be a concave-convex interlocking type, or a column hole mutual sleeve type, and the like.

2. The suction-controlled adjustable toothbrush consists of a movable brush head, a fixed brush head, a shaft, a brush handle and a twitch control head. Its control part is characterized in that the end of the 抦 of the movable brush head is 狞 and is formed with a bead-shaped through hole and integrated with the brush 抦. The small protrusion on the top of the folding control head is located in it (the twitch control head is in the Fix the rear half of the brush head in the through hole that is in the same direction as the brush handle).

3. The screw-controlled adjustable toothbrush consists of a movable brush head, a fixed brush head, a shaft, a brush handle and a rotation control head. The control part is characterized by a small cylinder protruding from the end of the handle of the movable brush head. After assembly, the small cylinder is located in a spiral groove at the top of the rotary control head. (Turn the control head on the fixed brush head. The back half of the round through hole in the same direction as the brush handle).

detailed description The four adjustable toothbrushes are described in detail below with reference to the drawings.

Figure 1 is a schematic diagram of the overall structure of a folding-controllable adjustable toothbrush.

The folding control type adjustable toothbrush is composed of a movable brush head 1, a fixed brush head 2, a shaft 3, a shaft 4, a brush handle 5 and a folding control head 6. The front half of the fixed brush head 2 (including the part with bristles and the front half of its handle) has a through hole (7. perpendicular to the direction of the handle and the same direction as the bristles), as shown in Figure 1-2. The rear part of the handle of the fixed brush head 2 is also a through hole (in the same direction as the brush handle). In order to create a large space for movement, the middle of the hole is small in size and large in the outer size, like an hourglass. 6 is in it, and is combined with the hole walls on both sides through the shaft 4 at the smallest intermediate size, so that the control head 6 can move up and down freely within a certain angle; the shaft 3 passes through the shaft on the handle of the movable brush head 1 The hole 8 and the shaft hole 9 on the shank for fixing the brush head on the outside thereof connect them. The end of the movable brush head 1 is combined with the top end of the above-mentioned control head 6, and the combination methods are various. In the figure, a concave-convex interlocking type is adopted, and a column hole mutual sleeve type is also used. Therefore, when the brush handle 5 is folded upward, the front of the control head 6 integrated with the shaft 4 is lowered due to the action of the shaft 4, that is, the movable brush head 2 is under the dual action of the shaft 3 and the control head 6, The part with bristles at the front end will rise to a certain degree, that is, it is higher than the fixed brush head 2 that is not moving around, so that the bristles look like "convex" in Chinese characters from the left and right sides. The characteristic of the shape is that it is equivalent to a small local brush head. This can overcome the shortcomings of incomplete contact due to the large area of the brush head, so that the uneven chewing surface of the molars can be cleaned very effectively. 5. Through the action of the shafts 3, 4 and the deflection control head 6, the movable brush head 1 is lower than the fixed brush head 2, that is, a "convex" shape is formed. At this time, the bristles raised on both sides can effectively avoid teeth. The obstruction of the corners is like an elongated arm, which effectively cleans the inside of the teeth and where the roots contact the gums, that is, to achieve the intended purpose. In addition, the movable brush head 1 can be integrated with the control head 6 and the brush handle 5 while omitting the shaft 3, which can also achieve the intended purpose. In order to make the control feel more comfortable and easier to maintain stability, the folding control 6 and its The inner wall of the contact hole makes a concave-convex groove that cooperates with each other, that is, the surfaces they contact are like two washboards facing each other. This treatment can make the control more powerful and difficult to deform after adjustment. ) The choice of the position, size and number of the grooves allows the user to know the degree of lifting of the movable brush head through the feel of the groove and is stable after each adjustment.

In addition, the function of preventing tooth ¾ described in "Content ⁵³ " is realized by adjusting the adjustable toothbrush into a "concave ³ 'shape before brushing the teeth, and squeezing the teeth into the groove in the middle of the brush head. With a few brushes, you can brush your teeth ¾ 5 away and prevent large pieces of toothpaste from falling. The following are the same and will not be described again.

The following three adjustable toothbrush heads are consistent with this adjustable toothbrush, so they will not be described in detail, and only their control parts will be described in detail.

The suction-controlled adjustable toothbrush has the same front half as the previous one (the middle of the entire brush head is the upper and lower through holes). The movable brush head 11, the fixed brush head 12, the shaft 13, the brush handle 14 and the twitch The control head 10 is configured.所述可活 The said live The end of the handle of the movable brush head 11 is thin and is engraved into a through hole 15 as shown in FIG. 2-1. The through hole may be a bead shape, a straight shape, or the like. The twitch control head 10 integrated with the brush handle 14 passes through a hole at the rear of the fixed brush head 12. The control head 10 is shown in Figure 2-2. The end is thin and has small protrusions 16. After the toothbrush is assembled, it is placed in the through hole 15 described above. Because the through hole 15 moves relative to the control head, The direction is inclined. At the same time, since the control head 10 where the protrusion 16 is located can only move horizontally, when the handle 14 is drawn outward, the protrusion 16 slides in the through hole 15 and the corresponding brush head at the same position The handle will rise to a certain degree, that is, the brush head part will drop to form a "concave" shape, otherwise pushing it inward will become a "convex", which achieves the purpose. In order to make the user feel better and make the control of each step more stable, the surface of the control head and the through hole in contact with it can be processed into the concave-convex groove described in the folding control method, or the method of inconsistent inner diameter segmentation can be adopted (Essentially the case where the longitudinal uneven groove is elongated).

The screw-controlled adjustable toothbrush is composed of a movable brush head 17, a fixed brush head 18, a shaft 19, a brush handle 21 and a rotation control head 20. The movable brush head 17 is installed in the through hole in the front half of the fixed brush head 18, and the groove 23 at the front end of the movable brush head 17 is engaged with the small protrusion 22 at the end of the movable brush head 17.

The front half of the toothbrush is the same as the two mentioned above (the middle of the entire brush head part is an upper and lower through hole). The movable brush head 17 is characterized by a small cylinder 22 protruding at the end of its handle. Figure 3-1 is Its front view. The rotation control head 20 integrated with the brush handle 21 passes through a hole at the back of the fixed brush head 18. The small cylinder 22 cooperates with a groove 23 at the top of the rear rotary control head 20, and the outer shape of the groove can be a variety of geometric curves. Here, a spiral shape is taken as an example. Figure 3-2 shows the front view of the control part. The figure and the enlarged left view (the distal end is omitted), wherein the banana-shaped part in the enlarged left view is the groove 23. It is characterized in that the distance between the center of the groove and the rotation center of the circular rotary control head 20 where it is located varies uniformly. When the brush handle 21 is rotated to the right, the rotation control head 20 connected to it is also rotated to the right synchronously, so that the spiral groove 14 at the top thereof is also rotated to the right synchronously. Since the movable brush head 17 can only move up and down That is, the protruding small cylinder 22 can only move in a vertical plane, and the geometric intersection point of the vertical plane and the spiral groove 23 rotating to the right gradually approaches the axis of rotation, and the geometric intersection point is exactly The position of the small cylinder 22 at the end of the movable brush head is reduced as the space position of the small cylinder 22 at the end is lowered to the right, so that the front half of the movable brush head 17 is raised, which is a "convex ⁵ 'shape. Conversely, turning to the left into a "concave" shape achieves the purpose. In order to prevent the control brush handle from falling, make the user feel good, and make the control of each step more stable, the different calibers or concave-convex grooves described in the above two methods can be used to handle the contact between the rotary control head 20 and its outside. surface. In order to make the screwing more convenient, the brush handle can be processed into a prism shape or a few simple ribs can be added.

The push-control adjustable toothbrush is composed of a movable brush head 24, a fixed brush head 25, a shaft 26, a brush handle 29, a guide groove 28, and a control sleeve 27. There is a through hole in the middle of the front part of the fixed brush head 25 to the handle 29, and there is a movable activity in the through hole. Moving the brush head 24, the middle and rear part of the rod is combined with the brush handles on both sides through the shaft 26, and the parts outside the two ends of the control sleeve 27 are slightly larger than the brush handles 左右 on the left and right sides of the brush cover. It is sloped or stepped. The brush handle at the same position as the shaft 26 has guide grooves 28 on both sides of the brush handle, and the control sleeve 27 is locked therein. When the control sleeve 27 is pushed forward, the leading edge of the control sleeve 27 will press the handle of the movable brush head 24 ( (Slightly higher), and the rear edge of the control sleeve 27 is also in contact with the handle of the movable brush head 24, so that the adjustment is very stable, so that the handle (the front part of the shaft) of the movable brush head 24 will be lowered, that is, the movable brush The head is also lowered, thereby forming a "concave" shape. Similarly, when pulled backward, a "convex" shape will be formed, that is, the purpose is achieved. For more convenient control, some non-slip treatment can be done on the control sleeve and brush handle. In addition, the control sleeve 27 can also be directly sleeved on the brush handle or buckled on the lower edge of the brush handle, that is, the guide groove 28 described above is not required.

Figure 5-1 shows the front and top views of the movable brush heads 1, 11, 17, 24 in the "embedded" combination mode

Figure 5-2 is a partial front view and a partial top view of the fixed brush heads 2, 12, 18, 25 in the "embedded" combination mode. We call the movable brush heads 1, 11, 17 used in the above four adjustable toothbrushes. , 24, and fixed brush heads 2, 12, 18, and 25 are combined by a shaft 3, 13, 19, and 26 as a "shaft type". In order to make production easier and make the handles flexible, the "shaft" combination used in the above four adjustable toothbrushes can be replaced with the "embedded" combination shown in Figures 5-1 and 5-2. . As shown in Figure 5-1, a symmetrical semi-axis 30 is set on both sides of the handle of the movable brush head (the place where the shaft hole was originally). Correspondingly, the handle of the fixed brush head on the outer side (originally the shaft hole) is structured as shown in Fig. 5-2, that is, the entrance is small, and the large small groove 31 below is specifically the entrance. Is smaller than the size of the protruding half shaft 30 shown in FIG. 5-1, and the larger size below is similar to the size of the protruding half shaft 30 shown in FIG. 5-1, which is for the half shaft After pressing into the small groove 31, 30 can move freely without falling off easily. Place the movable brush head shown in Figure 5-1 into the through hole in the middle of the fixed brush head shown in Figure 5-2 (at this time, the half shaft 30 shown in Figure 5-1 is embedded in Figure 5-2 In the small groove 31 shown in the figure), the movable brush head made of this structure can also move up and down freely, which is no different from using a shaft.
