Description

Electric toothbrush motor fixing mechanism
Technical Field
The utility model relates to an electric toothbrush field specifically is an electric toothbrush motor fixed establishment.
Background
The electric toothbrush makes the brush head generate high-frequency vibration through the quick rotation or vibration of the motor core, instantaneously decomposes the toothpaste into fine foam to deeply clean slits between teeth, and meanwhile, the vibration of the brush hair can promote the blood circulation of the oral cavity and has a massage effect on gum tissues.
In principle, electric toothbrushes have two main categories: rotation and vibration. The principle of the rotary toothbrush is simple, namely the motor drives the circular brush head to rotate, the friction effect is enhanced while the ordinary tooth brushing action is carried out, the rotary toothbrush is high in noise, the tooth surface is cleaned cleanly, the tooth gaps are relatively weak to clean, the abrasion to teeth is large, and the rotary toothbrush is not recommended to be used for a long time. The vibration type toothbrush is more complicated and higher in price. The electric driving vibrating motor is arranged in the vibrating toothbrush, so that the brush head can generate high-frequency swing perpendicular to the brush handle direction, but the swing amplitude is very small, generally about 5 mm for each of the upper part and the lower part, and the maximum swing amplitude in the industry is 6 mm. When the toothbrush is used for brushing teeth, on one hand, the brush head which swings at high frequency can efficiently finish the action of brushing teeth, on the other hand, the mixture of toothpaste and water in the oral cavity can generate a large amount of tiny bubbles by vibration for more than 30000 times per minute, and the pressure generated when the bubbles burst can deeply penetrate into gaps between teeth to clean dirt.
The electric toothbrush in the market mostly adopts the mode of oppression at present. But because the long-time deformation coefficient of the rubber part is larger, the size precision is difficult to control, so that the transmission that the high-speed vibration cannot be pressed is generated with higher probability, and potential safety hazards are generated to users.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an electric toothbrush motor fixed establishment to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides an electric toothbrush motor fixed establishment, includes brush holder inner chamber bottom fixed connection's spring, the motor lower extreme offsets with the spring, and the motor top is through fastener and brush holder fixed connection.
As a further aspect of the present invention: the mounting hole sites are arranged on two sides of the fastener, the limiting bulges are fixedly connected to the outer sides of the upper ends of the brush handles, and the mounting hole sites are matched with the limiting bulges in a clamping mode.
As a further aspect of the present invention: the bottom of the inner cavity of the brush handle is provided with a spring fixing groove.
As a further aspect of the present invention: the outer side of the motor is connected with the brush handle through a motor rubber sleeve.
As a further aspect of the present invention: the fastener is made of POM.
Compared with the prior art, the beneficial effects of the utility model are that: 1. the spring, the U-shaped motor rubber sleeve and the clamping position are tightly assembled to form the grasping mechanism, so that the mechanism is safer and more reliable and is not easy to fall off; 2. the long-acting structural design is adopted, and the injection molding is performed at one time, so that the injection molding machine is safe and environment-friendly and has no health hidden trouble for users; 3. the noise generated by high-speed vibration can be effectively reduced, and the hearing health of a user can be protected; 4. the assembly is more convenient, the motor is easier to take out, and the phenomenon that internal parts such as foreign matters exist in the screw is avoided; 5. the wire installing groove on the bracket can facilitate the long-term effectiveness and safety of the wire.

Detailed Description
The technical solution of the present patent will be described in further detail with reference to the following embodiments.
The first embodiment is as follows: referring to fig. 1-4, a motor fixing mechanism for an electric toothbrush includes a spring 2 fixedly connected to the bottom of an inner cavity of a brush holder 1, a lower end of a motor 7 is abutted against the spring 2, and the top of the motor 7 is fixedly connected to the brush holder 1 through a fastener 3.
Mounting hole sites 4 are formed in two sides of the fastener 3, a limiting protrusion 5 is fixedly connected to the outer side of the upper end of the brush handle 1, and the mounting hole sites 4 are in clamping fit with the limiting protrusion 5.
The top of the motor 7 is connected with the fastener 3 through a motor rubber sleeve 6.
The fastener 3 is made of POM.
Example two: this embodiment is a further improvement of the previous embodiment: a spring fixing groove 8 is formed in the bottom of the inner cavity of the brush handle 1, and therefore the spring 2 can be conveniently installed.
Other descriptions: 1. the circuit board of the motor 7 is attached to the whole back surface, and three points are added for positioning. And the built-in motor rubber sleeve 6 sinks, so that the distance between the motor rubber sleeve and the central shaft is further reduced, and the safety distance is further increased.
2. The fastener 3 adopts a shape of bilateral symmetry, avoids deformation, adopts a downstream glue type design on the rib for assembly activity, further reduces the internal stress of the material, and is beneficial to the long-term safety of the device.
3. The assembly position of the motor 7 adopts the design of a replaceable insert type, so that the finished product is convenient to be suitable for motors of different models.
4. The tail part of the device is designed with an upgradable wireless charging design, and the diversification of products is enriched.
5. The wiring groove is arranged on the inner side of the device, so that long-term effectiveness and safety of wires can be facilitated.
6. The single-sided main row element is adopted on the circuit board of the device, so that the volume of the product is effectively reduced.
7. The device circuit board is arranged at a safe distance, and a charging pad is arranged in the device circuit board, so that the safety performance is enhanced.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
