[0002] In recent years, people's living standards are constantly improving, so people's demand for tooth aesthetics and practicality is constantly improving, so more and more patients choose orthodontics. Because the structure of the fixed appliance is complex, the patient cannot disassemble it by himself, so it will hinder oral cleaning, cause plaque accumulation, and cause gingivitis and periodontitis, so oral cleaning is particularly important. For patients using fixed appliances, regular brushing cannot effectively remove dental plaque in the interproximal area.
[0003] In recent years, single-beam brushes and interproximal brushes have been widely used by orthodontic patients as auxiliary tools for mechanical control of plaque. Most of the interproximal brushes on the market are designed for periodontal disease patients and mainly include an interproximal brush rod, a flexible support rod and an interproximal brush head, with multiple size options. However, it takes a long time to clean the corners, and it is not easy to store and carry multiple cleaning tools. SUMMARY

[0028] In order to make the technical content, the purposes and effects of the present application clear, the following will be described in conjunction with the embodiments and the accompanying drawings.
[0029] Please refer to Figures 1-4 The technical scheme adopted by the present application is: an orthodontic four-in-one tooth cleaning brush, comprising a handle 1 and an orthodontic brush head 2 arranged at the front end of the handle 1.
[0030] The rear end of the handle 1 is provided with an open slot 11, and a rotating mechanism 3 is arranged in the open slot 11. The rotating mechanism 3 is respectively provided with a single bundle brush head 4, an interdental brush head 5, and a bracket gap brush head 6. The single bundle brush head 4, the interdental brush head 5, and the bracket gap brush head 6 are individually rotated from the open slot 11 to the outside of the open slot 11 through the rotating mechanism 3.
[0031] As can be seen from the above description, the present application integrates the four kinds of functional brush heads of the orthodontic brush head 2, the single bundle brush head 4, the interdental brush head 5, and the bracket gap brush head 6, and the orthodontic patient can use different brush heads to clean the teeth or the bracket wing 7. The use of multiple cleaning brush heads can effectively improve the cleaning effect. Through the rotating mechanism 3, the single bundle brush head 4, the interdental brush head 5, and the bracket gap brush head 6 can be stored in the open slot 11 in the handle 1, and the storage space is small, so it is convenient to carry.
[0032] Preferably, the rotating mechanism 3 comprises rotating wheels 31 and a ratchet wheel 32. The ratchet wheel 32 is fixed in the open slot 11. Three rotating wheels 31 are arranged in sequence on the outside of the ratchet wheel 32. Two pawls 33 are arranged on the rotating wheel 31. The two pawls 33 are symmetrically arranged. A spring 34 is arranged on the pawl 33, and the spring 34 is arranged in the rotating wheel 31. After the spring 34 is compressed, the front end of the pawl 33 abuts against the groove of the rotating wheel 31, and the tail end of the pawl 33 is limited by the connection with the nut. The outside of each rotating wheel 31 is connected with the single bundle brush head 4, the interdental brush head 5, and the bracket gap brush head 6, respectively.
[0033] From the above description, a rotating mechanism 3 with self-locking function is disclosed, the ratchet wheel 32 is fixed in the open slot 11, the orthodontic patient applies a certain force to the different rotating wheels 31 through the single bundle brush head 4, the interdental brush head 5 or the bracket gap brush head 6, the pawl 33 is separated from the groove of the ratchet wheel 32, and at the same time, under the action of the spring 34, the pawl 33 abuts against another groove of the ratchet wheel 32, forming self-locking, preventing the position deviation between the rotating wheel 31 and the ratchet wheel 32, and making the single bundle brush head 4, the interdental brush head 5 and the bracket gap brush head 6 more stable during use.
[0034] Preferably, the thickness size of the open slot 11 is 1.5-2mm.
[0035] From the above description, through the above setting, the fingers of the orthodontic patient can be inserted into the open slot 11, and the single bundle brush head 4, the interdental brush head 5 or the bracket gap brush head 6 can be rotated from the open slot 11 to the outside of the open slot 11 for cleaning work.
[0036] Preferably, the shape of the front end of the pawl 33 is matched with the shape of the groove of the ratchet wheel 32.
[0037] From the above description, through the above setting, the contact area between the pawl 33 and the ratchet wheel 32 is increased, forming a more stable fitting force, and the single bundle brush head 4, the interdental brush head 5 and the bracket gap brush head 6 are more stable during use.
[0038] Preferably, the spring 34 is a compression spring; the two ratchet wheels 32 are limited outside the ratchet wheel 32 through the reaction force of the compressed spring 34.
[0039] From the above description, through the above setting, under the action of the two symmetrically arranged springs 34, the front end of the pawl 31 is tightly fitted in the groove of the ratchet wheel 32, so as to limit the rotating wheel 31 outside the ratchet wheel 32, and the position deviation does not occur.
[0040] Preferably, the front end of the bracket gap brush head 6 is provided with a herringbone brush rod 61, and the herringbone brush rod 61 is uniformly provided with soft bristles 62.
[0041] From the above description, through the above setting, the soft bristles 62 on the herringbone brush rod 61 can quickly clean the hygiene at the corner of the bracket wing 7, and further improve the cleaning effect.
[0042] Preferably, the outward opening angle of the herringbone brush rod 61 is 40-60°; and the outward opening width size is smaller than the width size between the two bracket wings 7.
[0043] From the above description, through the above setting, the bracket gap brush head 6 can better clean the corner of the bracket wing 7, and the cleaning effect is improved.
[0044] The working principle of the utility model is:
[0045] The orthodontic patient uses the tooth cleaning brush, and the use mode of each brush head is consistent with the use mode in the prior art; when different cleaning brush heads need to be used in combination, the orthodontic patient can hook the front end of the single bundle brush head 4, the interdental brush head 5 or the bracket gap brush head 6 by fingers, and rotate the brush head out of the opening slot 11. Under the action of the rotating wheel 31, the ratchet wheel 32, the ratchet pawl 33 and the spring 34 in the rotating mechanism 3, the single bundle brush head 4, the interdental brush head 5 or the bracket gap brush head 6 has good stability during the cleaning process; during the cleaning process of the bracket gap brush head 6, the herringbone-shaped brush rod 61 at the front end of the bracket gap brush head 6 can be well embedded between two adjacent bracket wings 7, and the brush 62 can clean the corners on both sides of the bracket wing 7.
[0046] The above is only an embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent transformation or direct or indirect application in the related technical field based on the content of the utility model specification and drawings is also included in the patent protection range of the utility model.
