Description

Technical Field

[0001] The utility model relates to the technical field of interdental cleaning appliances, in particular to a double-headed interdental brush. Background Art

[0002] An interdental brush, also known as an interproximal brush, is a cleaning tool specifically designed to clean the spaces between teeth. Different from traditional toothbrushes, the interdental brush can reach deep into the spaces between teeth that are difficult for ordinary toothbrushes to reach, effectively removing food residues and dental plaque, and preventing gingivitis and periodontal diseases.

[0003] In the related art, most interdental brushes are in the structural form of a straight head or a bent head. The straight head means that the direction of the handle is parallel to the direction of the brush head, and when in use, the handle is held and inserted into the interdental space; the bent head means that the handle is perpendicular to the brush head, and when in use, the brush head is inserted into the interdental space, and the direction of the handle is perpendicular to the direction of the interdental space.

[0004] However, in the use of the above two structural forms, the overall cleaning effect of the interdental space cannot be guaranteed, the cleaning strength of dirt is insufficient, and there will be damage to the gums. Summary of the Utility Model

[0005] In view of at least one of the above technical problems, the utility model provides a double-headed interdental brush, and the structure is improved to improve the cleaning effect of the interdental space.

[0006] According to one aspect of the utility model, there is provided a double-headed interdental brush, comprising:

[0007] Two brush handles are symmetrically arranged, and the middle parts or the tails of the two brush handles are connected;

[0008] Brush heads are vertically arranged at the same end of the two brush handles, and the two brush heads are arranged oppositely;

[0009] Wherein, the two brush handles are movably connected, and the brush heads are configured to move closer to overlap or move away from each other when the included angle between the two brush handles changes.

[0010] Further, the brush head is made of silica gel.

[0011] Further, the brush head and the brush handle are detachably arranged.

[0012] Further, one end of the brush handle facing the brush head has a connecting part, and the bottom of the brush head has a connecting seat, and the connecting seat is detachably connected to the connecting part.

[0013] Further, the connecting seat and the connecting part are connected by snap connection, threaded connection, plug-in connection or magnetic attraction connection.

[0014] Further, positioners are provided on the brush handles and face each other to limit the degree of overlap of the two brush heads.

[0015] Further, the positioner includes a positioning rod and positioning teeth provided on the positioning rod. The positioning teeth are arranged at intervals and extend towards the direction of the other positioning rod.

[0016] Further, at least two positioning teeth are provided. When the first positioning tooth near the free end of the positioning rod engages, the ends of the two brush heads come into contact; when the second positioning tooth engages, the two brush heads overlap.

[0017] Further, an elastic body is further provided between the brush handles. The elastic body is used to provide a thrust force for the two brush heads to move away from each other.

[0018] Further, the brush handles are in the shape of pruning shears or tweezers.

[0019] The beneficial effects of the present utility model are as follows: By providing two opposite brush heads, the two brush heads can approach or move away from each other in opposite directions under the action of the brush handles, so that when cleaning the interdental spaces, they can enter both ends of a single interdental space simultaneously. Through the angular change of the two brush handles, the back-and-forth scrubbing of the brush heads can be achieved. Compared with the single-sided cleaning method in the prior art, the overall cleaning of the front and back of the interdental spaces is realized, thereby improving the cleaning effect of the interdental spaces.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manner.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0031] As Figures 1 to 7 shown, the double-headed interdental brush includes a brush handle 1 and a brush head 2, specifically as Figure 1 shown in: There are two symmetrically arranged brush handles 1, and the middle parts or tails of the two brush handles 1 are connected; in the embodiment of the present utility model, the brush handle 1 can be set as a structure in the shape of pruning shears as Figure 1 shown, that is, the middle part of the brush handle 1 is connected by a rotating shaft, and the angle of the brush handle 1 can be increased or decreased by finger operation; in addition, in some embodiments of the present utility model, the brush handle 1 can also be set as a forceps-like structure, specifically as Figure 6As shown in the figure, the brush handle 1 is connected at the tail, and the operator only needs to change the force of pinching the tweezers to achieve the change in the distance between the ends of the tweezers. Of course, it should also be noted here that in order to facilitate the use of the handle at an angle parallel to the teeth, the straightness of the brush handle 1 can be changed. For example, by setting the angle between the front end and the rear end of the brush handle 1 to 40 to 80 degrees, it is convenient for the brush head 2 to enter the tooth gap. The brush head 2 is vertically arranged at the same end of the two brush handles 1, and the two brush heads 2 are arranged oppositely. It should be noted here that in the embodiments of the present invention, the opposite arrangement has two implementation manners, horizontal and vertical. Please refer to Figure 1 , the horizontal opposite arrangement can be that the free ends of the two brush heads 2 face each other. Through this arrangement, the upper and lower cleaning can be carried out after inserting from both sides of the teeth; in another embodiment of the present invention, the vertical opposite arrangement is as shown in Figure 7 , the two brush heads 2 shown in the figure are both arranged in a direction perpendicular to the brush handle 1. Through this arrangement, the two brush heads 2 can face the same direction, and then it is possible to insert perpendicularly to the gum into the tooth gap and then perform reciprocating cleaning in the horizontal direction. The brush head 2 generally includes a thin rod-shaped structure for support and bristles arranged on the thin rod. When specifically setting, in order to protect the gums and avoid damage to the teeth, the brush head 2 is made of silica gel material. The specific structural form of the brush head 2 can be set by those skilled in the art according to needs, and will not be elaborated here; in the embodiments of the present invention, the two brush handles 1 are movably connected, and the brush heads 2 are configured to move closer to or away from each other when the angle between the two brush handles 1 changes. The movable connection here means that the form between the two can change. Specifically, it means that the angle between the two can change; when specifically setting, it can be connected by a rotating shaft, or can be set as shown in Figure 6 , connected by an elastic plate-like structure as shown in the figure.

[0032] In the above embodiments, by setting two opposite brush heads 2, the two brush heads 2 can approach or move away in opposite directions under the action of the brush handle 1, so that when cleaning the tooth gap, they can enter the front and rear ends of a tooth gap at the same time, and the back-and-forth washing of the brush head 2 can be realized by changing the angle of the two brush handles 1. Compared with the single-sided cleaning method in the prior art, the overall cleaning of the front and back of the tooth gap is realized, thereby improving the cleaning effect of the tooth gap.

[0033] On the basis of the above embodiments, in order to facilitate the replacement of the brush head 2, the brush head 2 and the brush handle 1 are detachably arranged. In some embodiments of the present invention, specifically as shown in Figure 2As shown, one end of the brush handle 1 facing the brush head 2 has a connecting portion 11, and the bottom of the brush head 2 has a connecting seat 21. The connecting seat 21 is detachably connected to the connecting portion 11. There are various specific detachable connection methods between the connecting seat 21 and the connecting portion 11. For example, it can be a snap connection, that is, by setting a protrusion or a groove on the connecting portion 11 to engage with the corresponding part on the connecting seat 21; or it can also adopt a threaded connection, that is, the connecting seat 21 has threads and the connecting portion 11 has a threaded hole corresponding to the threads, and the brush head 2 is tightened or removed by rotation; in addition, in the embodiments of the present invention, the connecting seat 21 and the connecting arm can also adopt a plug-in connection or a magnetic attraction connection. Of course, it should be pointed out here that the plug-in connection can be achieved by interference fit or by means of magnetic attraction, and a magnetic connecting member is provided at the bottom of the groove to improve the connection reliability.

[0034] In the embodiments of the present invention, in order to avoid excessive crossing of the brush heads 2, the brush handle 1 is provided with positioners 12 facing each other to limit the overlapping degree of the two brush heads 2. Of course, it should be pointed out here that there are various structural forms of the positioner 12. For example, it can adopt a telescopic rod or a retractable structure similar to an umbrella handle, etc. In the embodiments of the present invention, specifically as Figure 3 and Figure 4 shown, the positioner 12 includes a positioning rod 12a and positioning teeth provided on the positioning rod 12a. The positioning teeth are arranged at intervals and extend in the direction of the other positioning rod 12a. When specifically connecting the positioner 12, the positioning teeth on the two positioning rods 12a can be engaged with each other. When it is necessary to release the engagement, the relative distance between the two positioning rods 12a is increased. In some embodiments of the present invention, at least two positioning teeth are provided. When the first positioning tooth near the free end of the positioning rod 12a is engaged, the ends of the two brush heads 2 are in contact; when the second positioning tooth is engaged, the two brush heads 2 overlap. Through the setting of this structural form, the convenience of brushing the tooth gaps can be improved, and the user comfort can be improved.

[0035] In addition, in the embodiments of the present invention, as Figure 5 shown, an elastic body 3 is further provided between the brush handles 1. The elastic body 3 is used to provide a thrust for the two brush heads 2 to move away from each other. Of course, it should be pointed out here that there are various structural forms of the elastic body 3. For example, it can adopt a thrust spring, or a torsion spring can be provided at the rotating shaft of the brush handle 1, etc. The spring can be connected to the brush handle 1 at both ends, and even can be sleeved on the above-mentioned positioning rod 12a. When the double-headed toothbrush adopts the shape of tweezers, the plate body at the connection of the tweezers can be set as, for example, elastic metal to realize the automatic opening of the tweezers.
