Description

Rotary toothbrush

Technical Field

The invention relates to the technical field of toothbrushes, in particular to a rotary toothbrush.

Background

Most correct tooth brushing methods such as 'pasteurization' and the like use more complicated tooth brushing modes with different angles and different directions, tooth gaps are vertical, and the direction of a toothbrush handle is only horizontal, so that people can hardly do vertical, oblique, rotary and other actions during tooth brushing, and the methods are time-consuming and labor-consuming, and people are often difficult to master and develop good habits. Over the years, more people develop a horizontal brushing mode, but the horizontal brushing mode is difficult to effectively remove food residues in tooth gaps and achieve the purpose of cleaning oral cavities, so that a toothbrush needs to be developed to solve the problems.

Preferably, the rotating brush wheel comprises a rotating part and a gear, and the rotating part is connected with the gear.

Preferably, a rack is arranged on the side face of the front part of the brush handle, and the rack is in toothed connection with the gear.

Preferably, a stroke groove is formed in the bottom face of the front portion of the brush handle, a stop block is arranged on the toothbrush head, and the stop block is located in the stroke groove.

Preferably, the number of the bristles is three, and the three bundles of bristles are arranged in a crossed manner.

Preferably, a plurality of upright bristles are equidistantly arranged on the front part of the brush handle from front to back.

Preferably, the gear is fixed on a rotating part, and the rotating part and the gear are both positioned on the front side of the brush holder.

Preferably, the gear is fixed in the rotating part bottom, brush holder front portion includes head and shoulder, the rack is located the shoulder both sides, the gear is located the shoulder side, the rotating part is located the shoulder top.

The invention has the advantages that:

for a user who is used to brush teeth transversely, when the toothbrush is brushed back and forth, the rack at the front part of the brush handle can drive the rotary brush wheel to rotate back and forth, and because the bristles on the rotary brush wheel are crossed and separated and are spiral, food residues and bacteria in tooth gaps can be efficiently cleared away when the rotary brush wheel rotates, so that the aim of cleaning the oral cavity is fulfilled.

Detailed Description

The technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments described herein without the need for inventive work, are within the scope of the present invention.

The first embodiment is as follows:

a rotary toothbrush comprises a toothbrush head 2, a toothbrush handle 1 and a rotary brush wheel 3, wherein the toothbrush head 2 is connected to the front portion of the toothbrush handle 1 in a sliding manner, the rotary brush wheel 3 is rotatably connected with the toothbrush head 2, a plurality of bristles are arranged on the rotary brush wheel 3, the rotary brush wheel 3 is in tooth joint with the front portion of the toothbrush handle 1, the toothbrush head 2 can drive the rotary brush wheel 3 to rotate through reciprocating movement in the front portion of the toothbrush handle 1, the rotary brush wheel 3 comprises a rotary portion 5 and a gear 4, the rotary portion 5 is connected with the gear 4, a rack 6 is arranged on the side face of the front portion of the toothbrush handle 1, the rack 6 is in tooth joint with the gear 4, a stroke groove 7 is arranged on the bottom face of the front portion of the toothbrush handle 1, a stop block 8 is arranged on the toothbrush head 2, the stop block 8 is located in the stroke groove 7, the bristles are three in number and are arranged in a crossed manner, a plurality of upright bristles are arranged on the front portion of the toothbrush handle 1 from front portion to back at equal intervals, gear 4 is fixed on rotating part 5, rotating part 5 and gear 4 all are located brush holder 1 front portion side.

The working principle of the toothbrush is that when a user brushes teeth back and forth, the toothbrush head 2 can move back and forth on the front part of the toothbrush handle 1, so that the gear 4 moves back and forth on the rack 6, the gear 4 is driven to rotate, the gear 4 drives the rotary brush wheel 3 to rotate integrally, the brushing range of bristles is larger when the rotary brush wheel 3 rotates, the same effect of up-and-down brushing can be achieved, and tooth gaps can be cleaned more efficiently, wherein the stop block 8 can move back and forth in the stroke groove 7, the stop block 8 has a limiting effect, and when the stop block 8 touches the wall of the stroke groove 7, the toothbrush handle 1 cannot move forwards or backwards continuously.
