CN2520151Y - High-efficiency automatic teeth washing device - Google Patents

Abstract

The utility model relates to a high efficiency automatic orthodromic teeth washing device, which is applied to washing oral cavity and teeth of family individuals. The device is mainly composed of a brush (14), a brush holder (12), a motor (9), a battery (3) and a switch (5). When one end of the switch is pressed down, the motor rotates due to the current coming from the battery, which rotates the brush through a transmission shaft. When the other end of the switch is pressed down, the motor will start reverse rotation, which enables the brush hair to poke along the direction of teeth space for smudgy clearance. The device has advantages of simple structure, small volume, convenient use and low manufacturing cost. The brush hair can kick out the dirt deep from the teeth space with no hurt to teeth, which can keep the oral cavity and teeth clean and healthy if the device is always used.

Description

High-efficiency automatic forward scaling device

The utility model relates to a high-efficiency automatic toothwashing device in the forward direction, which is suitable for family individuals to clean the oral cavity and teeth.

Due to the existing toothbrush, it is very inefficient to use the correct method of brushing from the root of the tooth to the end of the tooth, and the toothbrush feels dissatisfied. So most of them brush their teeth horizontally in the wrong way. Teeth are worn down over time, and it is difficult to remove the dirt between the teeth. The dirt is polluted by bacteria, which damages the mouth and teeth, leading to many diseases, so I have to go to the doctor. The doctor found that the teeth had been rotted after washing the teeth with an ultrasonic scaler. Though this dental cleaning machine can clean teeth, it is expensive, bulky, complex in structure, high in technical requirements for use, and ordinary users cannot afford it, so it is difficult to use it frequently.

The purpose of the utility model is to provide an improved high-efficiency automatic forward tooth cleaning device. It has the advantages of simple structure, small size, convenient use and low cost, and can satisfy everyone's frequent use.

In order to achieve the above object, the technical solution of the utility model is:

The high-efficiency automatic tooth cleaning device mainly consists of a brush, a brush holder, a motor, a battery, and a switch. Press one end of the switch to make the current of the battery flow into the motor to make the motor rotate, drive the brush to rotate through the transmission shaft, and move laterally close to the teeth. When brushing the other row of teeth, press the other end of the switch to change the direction of the current , the motor and the brush are reversed, so that the bristles always follow the direction between the teeth, and the dirt is removed.

The utility model has the following effects:

1. Simple structure, small size, easy to use, low cost, everyone can buy and use it.

2. The bristles can penetrate deep into the gap between the teeth and remove dirt along its direction without hurting the teeth. Regular use can keep the oral cavity and teeth clean and hygienic. Save the time and cost of going to the hospital for teeth cleaning.

Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:

Accompanying drawing 1 is the partial sectional diagram of the utility model.

The device includes a brush (14) sleeve frame (16) inner hole to entangle the brush shaft (15), one side is loaded into the brush frame (12), the other end is loaded into the drive shaft (11), and the sealing ring (13) It is installed between the transmission shaft and the inner tube of the brush holder to prevent dirt from entering. Brush holder (12) packs into casing (4) upper end, and transmission shaft also packs into motor shaft (10) simultaneously, so that the replacement of hairbrush after wearing and tearing. The motor (9) is fixed in the casing, the electrode contacts (7) and (17) are installed at the bottom, and the switch (5) is installed in the middle and upper part of the casing; the middle positive contact (8) communicates with the battery (3), and the negative contact Points (6) and (8) are communicated with spring (2) by conductor (not shown in the figure), and battery cover (1) is covered in casing rear end. During use, one end of the switch (5) is pressed, the negative pole contact (6) communicates with the electrode contact (7), and the positive pole contact (8) communicates with the electrode contact (17). The electric current of battery (3) leads motor (9) motor shaft (10) to rotate. The hairbrush is driven to rotate by the transmission shaft (11). Press the other end of the switch (5) when needed, the negative pole contact (18), the positive pole contact (8) communicate with the electrode contacts (7) and (17) respectively, and lead to the reverse change of the rotation of the motor, so that the hair The brush rotates in reverse.

Claims (2)

1, this practically relates to a kind of efficiently toothwash device forward automatically, it is characterized in that: battery (3) leads to motor (9) by switch (5) rotates motor shaft (10), and hairbrush (14) is rotated by power transmission shaft (11), stock (16) is enclosed within brush axle (15) upper end, side and brush holder (12) join, there are sealing ring (13) and brush holder (12) sealing in power transmission shaft (11) outside, and dress brush holder lower end, casing (4) upper end has the spring (2) in the battery cover (1) to hold out against battery cathode.

2, (described device, switch (5) upper contact (6), (8) and (8), (18) are write electrode contacts (7) respectively, (17) contact, the hairbrush direction of rotation according to claim.
