Problems solved by technology

[0003] The above drive unit is designed to provide water column pressurization, so the eccentric shaft moves very fast, in order to quickly drive the action rod to form a continuous strong water column, so the friction between the eccentric shaft and the shaft, the friction between the bush and the eccentric shaft , The friction between the bushing and the end of the action rod is quite severe, so when the action rod pushes the water column, the distance between the friction loss between the components will cause the action rod to collide, which will generate a lot of noise and affect people's normal life. use
In addition, the frequency vibration generated by the high-speed operation of the drive unit of the above-mentioned dental flosser will be transmitted to the water spray head. When people use it, the water spray head will vibrate with the teeth, which will cause the user to feel uncomfortable.

Embodiment Construction

[0018] The present invention will be further described below in conjunction with accompanying drawing.

[0019] Such as figure 1 with figure 2 As shown, the present invention is a sound-absorbing, anti-vibration electric dental flosser, which includes a water tank 100 filled with water, a water spray head 200 , a driving unit 300 and a piston pump 317 .

[0020] The drive unit 300 includes a transmission motor 310, the transmission gear 311 of the transmission motor 310 meshes with the side of a gear 312 connected with an eccentric shaft 313, the gear 312 is passed through a fixed shaft 314, the The eccentric shaft 314 cooperates with a bushing 315 to pass through one end of an actuating rod 316. The other end of the actuating rod 316 is assembled with a reciprocating piston pump 317. The water inlet pipe 318 of the piston pump 317 is connected to the water tank. 100 is connected, the outlet pipe 319 of the piston pump is connected with the water spray head 200, the drive u...

Abstract

The invention discloses an electric dental water jet capable of reducing noise and preventing vibration, comprising a water tank, a sprinkler head, a drive unit and a piston pump, wherein the pump body of the piston pump is arranged between the water tank and the sprinkler head; a piston rod is connected with the drive unit; the drive unit and the piston rod partial liquid of the piston pump are sealed in a noise reducing cover; and the drive unit, the liquid and the noise reducing cover are arranged in the water tank. The beneficial effect is as follows: the noise and vibration generated when the drive unit and the piston pump work are reduced through the water in the water tank.

Description

technical field [0001] The invention relates to an appliance for cleaning teeth, in particular to an electric dental flosser. Background technique [0002] At present, commonly used dental flossers include a water tank, a drive unit and a water spray head. The drive unit is located on the outer side of the water tank. The drive unit includes a transmission motor. meshing, the gear is mounted on a fixed shaft, the eccentric shaft cooperates with a bush and is mounted on one end of an actuating rod, and the other end of the actuating rod is assembled with a reciprocating piston pump. The outlet pipe of the piston pump is connected with the water spray head. [0003] The above drive unit is designed to provide water column pressurization, so the eccentric shaft moves very fast, in order to quickly drive the action rod to form a continuous strong water column, so the friction between the eccentric shaft and the shaft, the friction between the bush and the eccentric shaft , The...
