Description

Technical Field

[0001] This utility model relates to the field of electric toothbrush technology, specifically a 360-degree rotating intelligent paste-free electric toothbrush. Background Technology

[0002] An electric toothbrush is a modern oral hygiene tool that uses an electric motor to drive the brush head to rotate or vibrate, providing a more efficient and thorough cleaning. The rapid rotation or vibration of the motor core creates high-frequency vibrations in the brush head, instantly breaking down toothpaste into fine foam that deeply cleans between teeth, promotes blood circulation in the mouth, and massages the gum tissue. Electric toothbrushes primarily use three types of brush head movements: reciprocating linear motion, rotary motion, and sets that combine two types of brush heads. The bristles are made of soft plastic fibers with spherical tips, ensuring they won't damage teeth or gums while maintaining effective brushing.

[0003] An electric toothbrush, as disclosed in publication number CN222032691U, comprises a manual toothbrush and a handle joined together. The handle includes a main housing and at least a portion of a control component, a drive component, a mounting component, a connector, and an inner support disposed within the main housing. The inner support is connected to the mounting component. The control component and the drive component are disposed in at least one of the inner support and the mounting component, and the control component is electrically connected to the drive component. The manual toothbrush extends into the mounting component. The connector is used to move relative to the mounting component in the length direction under external force and to apply force to the mounting component. The mounting component applies force to the manual toothbrush and fixes the manual toothbrush in the mounting component. The electric toothbrush is adaptable to the manual toothbrush, which improves its versatility.

[0004] The existing traditional electric toothbrushes and ordinary manual toothbrushes have limited friction from their bristles, which is insufficient to remove plaque such as tobacco stains, tea stains, and coffee stains. In addition, traditional electric toothbrushes only swing back and forth at a certain angle around the axis of the disc toothbrush head, without rotating 360 degrees. Therefore, we provide a 360-degree rotating smart plaster-free electric toothbrush. Utility Model Content

[0005] The purpose of this invention is to provide a 360-degree rotating intelligent paste-free electric toothbrush to solve the existing problems mentioned in the background art.

[0011] Preferably, a silicone sleeve is provided on the outer side of the positioning wall, and the silicone sleeve is bonded to the positioning wall.

[0012] Preferably, a first snap-fit ​​plate is provided inside the toothbrush shell, and a second snap-fit ​​plate is provided at the upper end of the first snap-fit ​​plate. The toothbrush shell is used to position and connect the rotating rod through the first snap-fit ​​plate and the second snap-fit ​​plate.

[0013] Preferably, the lower end of the silicone cleaning brush head is provided with a snap-fit ​​groove, and the upper end of the passive shaft is provided with a snap-fit ​​block. The silicone cleaning brush head is assembled and connected through the snap-fit ​​groove at the lower end and the snap-fit ​​block at the upper end of the passive shaft.

[0014] Preferably, the silicone cleaning brush head has multiple sets of blades on its inner upper side, and the multiple sets of blades are evenly arranged inside the silicone cleaning brush head.

[0015] Preferably, the upper end of the drive shaft is provided with a mating component, the upper end of the mating component is disposed at the lower end of the driven shaft, and the drive shaft is rotatably connected to the driven shaft through the mating component.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] (1) This utility model incorporates selected cleaning materials such as pumice, alumina, silicone oil, and abrasion inhibitor into a silicone toothbrush head. After mixing in a certain proportion, the mixture is vulcanized and molded into a round toothbrush head. The friction generated during rotation, combined with the addition of silicone oil and abrasion inhibitor, and the addition of water during cleaning, can improve the heat dissipation effect. In the environment of accelerated cooling during cleaning, the teeth are cleaned at a certain speed, thereby achieving both excellent cleaning effect and no damage to the teeth. This solves the problem of limited friction generated by the bristles of traditional electric toothbrushes and traditional manual toothbrushes. It enables the cleaning of the tooth surface without toothpaste, and can also clean the plaque that ordinary toothbrushes cannot clean, such as tobacco stains, tea stains, and coffee stains.

[0018] (2) By changing the structure of the toothbrush head, the disc toothbrush head can achieve a fixed-point rotation effect. Then, by pulling and swinging the toothbrush head, the entire oral cavity and teeth can be cleaned. By adding a positioning wall that is lower than the toothbrush head surface around the rotating surface of the toothbrush head, after the toothbrush head enters the oral cavity, the cheek muscles and teeth on the outside of the oral cavity will exert a slight pressure on the toothbrush head, or a slight press on the toothbrush handle. In this way, the positioning wall will come into contact with the surface of the teeth and gums. The friction generated when the toothbrush head rotates will be offset by the friction generated by the positioning wall coming into contact with the surface of the teeth or gums, thus achieving the problem of positioning the toothbrush head. This solves the problem that traditional electric toothbrushes only swing back and forth at a certain angle like a pendulum around the axis of the disc toothbrush head, without rotating 360 degrees.

[0019] (3) This utility model minimizes the resistance torque by changing the fulcrum of frictional resistance, thus achieving the result of minimizing the torque required to hold the toothbrush handle. It adds a support point during the rotation of the toothbrush head by adding a positioning wall (the top of which is made of soft rubber to achieve comfort when it comes into contact with the tooth surface, and at the same time, to prevent the outer shell of the toothbrush head from hitting the teeth and gums during the rotation) around the toothbrush head. After the toothbrush head enters the mouth, the cheek muscles and teeth on the outside of the mouth will exert a slight pressure on the toothbrush head, or a slight press on the toothbrush handle. In this way, the positioning wall will come into contact with the surface of the teeth and gums. The friction generated when the toothbrush head rotates will be offset by the friction generated when the positioning wall comes into contact with the surface of the teeth or gums, thereby solving the problem of the toothbrush head hitting the mouth due to irregular movement when rotating 360 degrees.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Please see Figure 1-5 This utility model provides an embodiment of a 360-degree rotating intelligent paste-free electric toothbrush, comprising an electric toothbrush 1. The electric toothbrush 1 includes a toothbrush shell 11, a positioning wall 12, a silicone cleaning brush head 15, a passive shaft 16, and an active shaft 17. The active shaft 17 is disposed inside the toothbrush shell 11, the passive shaft 16 is disposed at the upper end of the active shaft 17, and the silicone cleaning brush head 15 is disposed at the front end of the passive shaft 16. The positioning wall 12 is disposed on the outer side of the silicone cleaning brush head 15. By adding selected cleaning materials such as pumice, alumina, silicone oil, and abrasion inhibitor to the silicone toothbrush head, and mixing them in a certain proportion, the brush head is vulcanized and formed into a round shape. Utilizing the friction generated during rotation, and by adding silicone oil and abrasion inhibitor, along with the addition of water during cleaning, the heat dissipation effect is improved. In the environment of accelerated cooling during cleaning, the teeth are cleaned at a certain rotation speed, thereby achieving both excellent cleaning effect and no damage to the teeth. This solves the problems of traditional electric toothbrushes and traditional ordinary toothbrushes. The friction generated by the bristles of a manual toothbrush is limited and insufficient to remove plaque from tobacco, tea, and coffee. By modifying the toothbrush head structure, a circular toothbrush head can achieve a fixed-point rotation. The entire mouth and teeth can be cleaned by pulling and oscillating the toothbrush head. A positioning wall 12, lower than the toothbrush head surface, is added around the rotating surface. When the toothbrush head enters the mouth, the cheek muscles and teeth exert slight pressure on the toothbrush head, or a slight press on the handle. This causes the positioning wall 12 to come into contact with the tooth and gum surfaces. The friction generated by the rotating toothbrush head is offset by the friction generated by the positioning wall 12 against the tooth or gum surface, thus achieving the problem of positioning the toothbrush head. This solves the problem of traditional electric toothbrushes 1, which only swing back and forth at a certain angle around the axis of the circular toothbrush head, without 360-degree rotation.

[0028] Please see Figure 4The toothbrush shell 11 has a first slot 5 at the front end, and a drive shaft card 14 is provided in the first slot 5, and the drive shaft card 14 is fitted and connected to the first slot 5.
