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.

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.
