Description

Direct transmission vibration type electric toothbrush

Technical Field

The utility model belongs to the technical field of electric toothbrush technique and specifically relates to a direct transmission vibrations formula electric toothbrush.

Background

Electric toothbrushes are a relatively new type of tooth cleaning implement that is widely used in many developed countries for dental care. Electric toothbrushes are increasingly used as a new type of tooth brushing tool. The brush head of the electric toothbrush is electrified with high-frequency vibration to rapidly decompose toothpaste into fine foams, and the foams can penetrate into gaps between teeth. Compared with a manual toothbrush, the toothbrush can more thoroughly remove 38% of dental plaque, and can more effectively reduce exogenous tooth staining caused by drinking tea, coffee and other reasons.

The electric toothbrushes in the current market have uneven quality, the magnetic suspension motor is used for achieving the best quality and hand feeling, but the cost is high, so that the price requirement of consumers is met; the low-power electric toothbrush realizes the vibration of the toothbrush head in a hollow cup motor mode. The connection between the hollow cup motor and the brush head adopts the following mode: the shell and the shaft are encapsulated and fixed into a whole, the motor is arranged on a support in the shell, and the brush head is inserted on the shaft exposed out of the shell; when the hollow cup motor is started to vibrate, the whole toothbrush shell is driven to vibrate in the shell, and the toothbrush shell vibrates, namely, the shaft also vibrates, so that the vibration of the toothbrush head is realized (an indirect transmission structure mode). When the vibration frequency is more than 7000 r/min, the vibration sense of the toothbrush head is very strong when the toothbrush head is held by a hand, the use comfort level is extremely poor, and meanwhile, the vibration quantity is reduced due to the fact that vibration is restrained by the hand when the toothbrush head is held by the hand after the toothbrush head is held by the hand, and the vibration quantity of the toothbrush head is extremely poor. Affecting the use effect of consumers.

SUMMERY OF THE UTILITY MODEL

In order to solve the above technical problem, an object of the present invention is to provide a direct transmission vibration type electric toothbrush. The utility model discloses a specific technical scheme as follows:

the utility model provides a direct transmission vibrations formula electric toothbrush, includes upper cover and lower cover, the upper cover lock is in the lower cover, form the brush holder, be equipped with battery, circuit board and an organic whole axle in the brush holder, the axle sleeve of an organic whole axle is embedded to have the motor, an organic whole axle with the motor forms the integral type structure, and the brush head is fixed the end is stretched out to the integrative axle of brush holder front end, the motor overcoat is equipped with the motor cover, the both ends of motor cover are equipped with first shock pad and second shock pad respectively.

Preferably, a brush cover is further arranged at the joint of the brush head and the brush handle, a through hole is formed in the brush cover, and the integrated shaft penetrates through the brush cover and then is connected with the brush head.

Preferably, the other end of the brush handle is further provided with a brush handle cover, a fixing plate is arranged between the brush handle cover and the battery, and the other end of the battery is connected with the circuit board.

Preferably, the motor is a hollow cup motor.

Preferably, the battery is a rechargeable lithium battery.

Preferably, the brush head is made of food-grade PP materials.

Preferably, the integral shaft of the motor is made of 304 stainless steel.

The utility model provides a pair of directly transmit vibrations formula electric toothbrush, its beneficial effect lies in: in order to ensure that the vibration quantity is not damaged and the vibration sense is held to fall the end, adopt the lug connection mode with the brush head and motor, when the motor vibrates, the vibration quantity is direct to be transmitted for the brush head from an organic whole axle, has the shock pad to cushion simultaneously between an organic whole axle and the brush holder, then the vibration quantity of motor is whole to be transmitted for the brush head, the vibration sense on the brush holder is cushioned the back by the shock pad basically simultaneously, only minimum vibration sense on the brush holder to satisfy the user and to the vibration quantity and feel the requirement.
