[0023] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 4 As shown, the foldable toothbrush of this embodiment includes a handle portion 1 and a handle portion 2. The handle portion 1 and the handle portion 2 are hinged via a rotating shaft mechanism 3. A protective cover 4 is provided on the handle portion 1. The handle portion 1 includes bristles 101, a toothbrush head 102 and a toothbrush handle 103. The protective cover 4 includes a brush head cover portion 401 and a brush handle cover portion 402. The brush head cover portion 401 is provided with an opening 403 for the bristles 101 to pass through. The foldable toothbrush is hingedly connected by a rotating shaft mechanism 3 between the brush handle part 1 and the handle part 2, so that the toothbrush shaft can be flipped and folded, which reduces the occupied space and is convenient for storage and carrying. At the same time, a protective cover 4 is provided on the brush handle part 1. The purpose is to cover the hard toothbrush head 102 and the toothbrush handle 103 with the softer protective cover 4 to prevent the toothbrush head 102 and the toothbrush handle 103 from directly contacting the inside of the oral cavity when brushing teeth, thereby solving the problem of discomfort caused by the contact between the toothbrush head 102 and the toothbrush handle 103 and the teeth and scratching the oral cavity in the prior art. The structure is simple, the use is very convenient, and the user's comfort can be effectively improved.

[0025] Preferably, a housing cavity 1021 for accommodating bristles 101 is provided in the toothbrush head 102, a plurality of groups of connecting grooves 5 communicating with the housing cavity 1021 are provided on the outer periphery of the side wall of the toothbrush head 102, and a plurality of groups of connecting posts 6 penetrating the connecting grooves 5 are integrally formed on the inner periphery of the side wall of the brush head cover 401. In this embodiment, a plurality of groups of penetrating connecting grooves 5 are provided on the side wall of the toothbrush head 102, and the inner periphery of the side wall of the brush head cover 401 is formed with connecting posts 6 penetrating the connecting grooves 5 by an integral injection molding process, so as to prevent the brush head cover 401 from sliding and loosening on the toothbrush head 102, and effectively improve the connection stability between the brush head cover 401 and the toothbrush head 102.

[0026] Preferably, the bristles 101 include a base plate 1011 and a bristle body 1012, the outer periphery of the bristle body 1012 is provided with an annular sealing ring 7, and the inner periphery of the side wall of the toothbrush head 102 is provided with a first flange 8 for pressing the annular sealing ring 7 onto the base plate 1011. In this embodiment, the outer periphery of the bristle body 1012 is provided with an annular sealing ring 7, and the annular sealing ring 7 is pressed onto the base plate 1011 in cooperation with the first flange 8 on the side wall of the toothbrush head 102, which plays a sealing and waterproofing function, can prevent water leakage and accumulation in the accommodating cavity 1021, prevent the formation of mold, keep the toothbrush itself clean, and effectively protect the hygiene of use.

[0027] Preferably, the inner circumference of the side wall of the brush head cover 401 is provided with a second flange 9 for covering the first flange 8. In this embodiment, the second flange 9 on the side wall of the brush head cover 401 covers the first flange 8, which can also prevent moisture from leaking and accumulating in the brush head cover 401, keep the toothbrush clean, and protect the hygiene of use.

[0028] Preferably, a bubble baffle 404 is provided on one end of the brush handle sleeve 402 near the rotating shaft mechanism 3. During brushing, when the toothpaste foam flows to the bubble baffle 404, the foam will slide down along the bubble baffle 404 to prevent the foam from flowing to the handle 2 and affecting the user experience.

[0029] Preferably, the rotating shaft mechanism 3 includes a rotating shaft 301 provided at the end of the toothbrush handle 103 and a rotating shaft hole 302 provided at the end of the handle portion 2, and the rotating shaft 301 is inserted into the rotating shaft hole 302. In this embodiment, the rotating shaft 301 is provided at the end of the toothbrush handle 103, and the rotating shaft hole 302 is provided at the end of the handle portion 2. The structural form in which the rotating shaft 301 is inserted into the rotating shaft hole 302 has the advantages of simple structure, convenient and quick disassembly and assembly, and good connection stability. In other embodiments, the end of the toothbrush handle 103 can be set as the rotating shaft hole 302, and the end of the handle portion 2 can be set as the rotating shaft 301, which is not limited to this embodiment.

[0030] Preferably, the handle portion 2 is provided with a receiving groove 201 for receiving the brush handle portion 1. When the brush handle portion 1 is flipped and folded onto the handle portion 2, the brush handle portion 1 can be entirely embedded in the receiving groove 201, which can effectively reduce the volume after folding, occupy less space, and further improve portability.

[0031] Preferably, a plurality of limit plates 202 for abutting against the brush handle 1 are provided in the receiving groove 201. When the brush handle 1 is inserted into the receiving groove 201, the limit plates 202 can abut against the brush handle 1 to prevent the bristles 101 from contacting with the bottom of the receiving groove 201 and causing contamination, thereby keeping the toothbrush itself clean.

[0032] Preferably, an air-avoiding opening 203 is provided on the end of the handle portion 2 away from the rotating shaft mechanism 3. In the folded state, the user's fingers can directly contact the toothbrush head 102 through the air-avoiding opening 203, thereby rotating the handle portion 1 to open it, and it can be opened without using auxiliary tools, further improving the convenience of use.

[0033] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. For those skilled in the art, improvements and changes obtained without departing from the technical concept of the present invention should also be regarded as the protection scope of the present invention.
