Description

A kind of machinery electric toothbrush

Technical field

The utility model relates to consumer goods industries, and in particular to a kind of machinery electric toothbrush.

Background technique

Vehicles Collected from Market electric toothbrush mainly reaches teeth surfaces purpose using the vibration of brush head high-frequency, the technical solution There are following three disadvantages:

1. cleaning effect is limited, can only be effective to tooth plane, teeth crevice cleaning effect is poor.The most scientific side of brushing teeth Formula is to make bristle mobile from tooth root position toward occlusal surface, and oscillatory type bristle can only be of reciprocating vibration in minimum distance, bristle It can not effectively reach inside gap, so poor to the cleaning capacity of flank of tooth recess and teeth crevice position.

2. user is inconvenient for operation, brush dynamics are difficult to control.Oscillating electric tooth-brush is the high frequency vibrating by bristle Dynamic to reach cleaning effect, user needs to manually control elasticity of the bristle in conjunction with tooth face in use, if pressing Power is too small, and bristle is very little with face.If pressing force is excessive, bristle bending causes effectively to swing, and cleans energy Power will substantially reduce, and user experience is poor.

3. brushing efficiency is low, there are three the flank of tooth, the outer flank of tooth, inner toothed surface and the positive flank of tooth, oscillatory type electricity altogether for each zone teeth It can only be acted on a flank of tooth when dynamic toothbrush workpiece, efficiency is relatively low.

Utility model content

For the defects in the prior art, the utility model provides a kind of mechanical electric toothbrush, can be simultaneously to tooth Three faces are cleaned, and cleaning effect is more preferable, and brushing efficiency is higher.

A kind of mechanical electric toothbrush provided by the utility model, including brush handle and brush head, the brush head include two and are used for Clean side tooth surface rotational head and one for cleaning the swing brush head of the tooth field of conjugate action, the swings brush head includes brushing Plate and the first bristle being planted on brush board, the rotational head include spiral matrix and along matrix helical arrangement The second bristle, the brush head is removably connected on brush handle, is provided in the brush handle for driving brush Motor and the battery powered to motor, are additionally provided with the transmission mechanism connecting with brush head on the brush handle.It is described in cleaning Two rotational heads and a swing brush head move three faces for capableing of tray covered teeth together, and the area of cleaning is wide, high-efficient.

Further, the transmission mechanism include reduction gearbox and be connected to reduction gearbox output end transmission shaft, it is described to subtract The input terminal of fast case is connect with the motor, and the output end of the reduction gearbox includes that a swing output end and two rotations are defeated Outlet, the transmission shaft include and swing the swing rod and two rotations connecting respectively with two rotational heads that brush head is connect Bull stick, the swing rod are removably connect with swing output end, and the swingle is removably defeated with rotation Outlet connection.When needing replacing brush head, swingle and swing rod are extracted, old brush head can be removed, by the rotation of new brush head Bar and swing rod are plugged on the output end of the reduction gearbox.
