Background
For a long time, people generally use toothbrushes to clean teeth, however, the existing toothbrushes only can clean dirt and residues on the surfaces of the teeth, and are difficult to completely remove residues in gaps between the teeth, so that the teeth can generate 'dental calculus' after a long time, peculiar smell can be generated, and periodontitis can be caused. Therefore, people have to go to hospitals to wash teeth, which is high in cost and suffers from pain. Based on the above-mentioned deficiencies of toothbrushes, more and more people have now chosen to use tooth rinsers for tooth cleaning and health care. The tooth flusher mainly comprises a water pump and a spray head, and utilizes water flow with certain pressure to flush teeth, wherein the water flow can reach the parts which can not be reached by the toothbrush, so that the periphery, the top and the inner surface of the teeth are deeply flushed, and residues and harmful bacteria are removed.
However, the water pump of the existing tooth flusher mostly adopts a reciprocating piston structure, namely, the piston reciprocates in a piston cylinder, so as to generate negative pressure and pump the water source in the water tank to the spray head of the tooth flusher. The structure is easy to generate abrasion when the piston reciprocates, and the piston is easy to generate larger noise when being matched with the piston cylinder.

Detailed Description
The invention will be described in further detail with reference to the following detailed description and accompanying drawings: referring to fig. 1 to 5, the pump structure of the tooth flusher comprises a pump body 1, wherein a first bevel gear 11 is rotatably arranged in the pump body 1, a second bevel gear 12 engaged with the first bevel gear 11 is arranged on one side of the first bevel gear 12, the second bevel gear 12 is driven by a motor 13 fixed in the pump body, an eccentric shaft 11a is arranged on the end surface of the first bevel gear 11, and one end of a connecting rod 2 is sleeved outside the eccentric shaft 11 a;
the pump comprises a pump body 1 and is characterized in that a pump head 3 is fixedly arranged on one side of the pump body 1, the pump head 3 is provided with an internal cavity, a first channel 31 and a second channel 32 are arranged on the pump head 3, the internal cavity is communicated with the first channel 31 and the second channel 32, the first channel 31 is used for being connected with a spray head of a tooth flushing device, and the second channel 32 is used for being connected with a water tank of the tooth flushing device or being directly connected with an external water source. A check valve mechanism 5 is provided in the first passage 31 and the second passage 32.
The pump structure of the tooth flushing device further comprises a flexible diaphragm 4, the outer edge of the flexible diaphragm 4 is pressed between the pump body 1 and the pump head 3, and the central position of the flexible diaphragm 4 is fixedly connected with the other end of the connecting rod 2.
