The tooth flusher is used for cleaning teeth. A dental irrigator generally includes a water tank and a pump assembly for pumping water from the tank to clean teeth.

At the creation in-process that realizes this application technical scheme, the inventor discovers, and the water pump assembly of current tooth ware of washing only can go out the water pump in the water tank of tooth ware with washing the tooth, and the functional effect is comparatively single, and the tooth effect of washing is ideal inadequately, is difficult to satisfy the user to the requirement of washing the tooth, influences user experience.

Based on this, in order to solve the technical problem that the water pump assembly of the tooth flushing device in the related art has a single function and effect and affects user experience, the inventor provides the following scheme.

Referring to fig. 1 to 5, a water pump assembly 10 is provided in an embodiment of the present application for use in a dental irrigator including a water tank, an exemplary water tank 20 is shown in fig. 6 and 7. The water pump assembly 10 includes a pump body 11, a piston 12, and a driver 13, wherein:

pump body 11 has a pump chamber 110.

The piston 12 is arranged in the pumping chamber 110, and two opposite ends of the piston 12 respectively surround the chamber wall of the pumping chamber 110 to form a tooth flushing chamber 1101 and a stirring chamber 1102. The tooth punching chamber 1101 and the stirring chamber 1102 are blocked by the piston 12 and are not communicated with each other, so that the tooth punching chamber 1101 and the stirring chamber 1102 can work independently. It will be appreciated that the piston 12, when moving within the pumping chamber 110, changes the spatial dimensions of the die chamber 1101 and the agitator chamber 1102. The part of the pump body 11 where the tooth punching cavity 1101 is located is provided with a one-way water inlet 1101a and a one-way water outlet 1101b which are communicated with the tooth punching cavity 1101. It will be appreciated that the one-way water inlet 1101a is a one-way through-hole that only allows liquid to enter the tooth chamber 1101 and the one-way water outlet 1101b is a one-way through-hole that only allows liquid to exit the tooth chamber 1101. The tooth-flushing cavity 1101 is used for pumping liquid in the water tank from a one-way water inlet 1101a and pumping the liquid out from a one-way water outlet 1101b for flushing teeth. The pump body 11 is provided with a stirring port 1102a in the stirring chamber 1102, and the stirring port 1102a is used for allowing the liquid in the water tank 20 to enter and exit from the stirring chamber 1102 so as to stir the liquid in the water tank 20. It is to be understood that the stir port 1102a is a bi-directional through hole that allows both the liquid in the tank 20 to enter the stir chamber 1102 and the liquid in the stir chamber 1102 to exit the stir chamber 1102. The stirring chamber 1102 is used to pump the liquid in the tank through the stirring port 1102a and out through the stirring port 1102a to stir the liquid in the tank. The stir chamber 1102 is a closed cavity because the plunger 12 is required to draw fluid from the tank into the stir chamber 1102 and to expel fluid from the stir chamber 1102.

The power output of driver 13 is connected to piston 12 for driving piston 12 to reciprocate between the tooth flushing chamber 1101 and the stirring chamber 1102. It is to be understood that the driver 13 is a driving mechanism or driving device capable of providing a driving force for the reciprocating motion of the piston 12, and may be any one of the existing tooth irrigators.

It is understood that the additive may be various agents beneficial to the oral cavity and the teeth, but is not limited thereto, and the user may select one or more additives according to actual needs. For example, when the additive with the bactericidal effect is added, the modified liquid is adopted to rinse the teeth, so that the teeth and viruses, bacteria and harmful microorganisms in the oral cavity can be killed quickly and effectively; is beneficial to generating sterile water and is not harmful to people; for example, when an additive with halitosis removing effect is added, the teeth can be washed to remove halitosis and improve the oral cavity freshness; for example, when an additive having a tooth-bleaching effect is added, teeth can be bleached; for example, additives capable of eliminating active oxygen radicals from the human body or resisting oxidation may be added, but not limited thereto.
