Background
The tooth flusher is an auxiliary tool for cleaning the oral cavity, and mainly utilizes a pulse water flow impact mode to clean teeth and tooth gaps, and the flushing pressure of the tooth flusher is 0 to 90psi generally. The water pressure of the pulse water flow generated by the tooth flusher is generally the water pressure generated by tap water and a built-in pump, and the pump for the tooth flusher is generally a piston pump, namely, the reciprocating motion of a piston in the piston pump is utilized to lead the working volume of a pump cavity to be changed periodically, thus realizing the suction and discharge of liquid, and further forming the pulse water flow to clean teeth and tooth gaps.
The piston pump is also called as an electric reciprocating pump, can be divided into a single cylinder and a plurality of cylinders from the structure, and is characterized by higher lift. The piston pump consists of a pump cylinder, a piston, a water inlet one-way valve, a water outlet one-way valve, a water inlet pipe, a water outlet pipe, a connecting rod and a transmission device, and the piston is driven by power to reciprocate in the pump cylinder. The working process of the piston pump in the tooth flushing device is that when the piston does stretching motion, the water inlet check valve is opened, the water outlet check valve is closed, and water enters the pump cylinder through the water inlet pipe; when the piston is in compression movement, the water inlet check valve is closed, the water outlet check valve is opened, water pressure is formed in the pump cylinder, the water in the pump cylinder is pressed into the water outlet pipe, and water is repeatedly fed and discharged in such a way that water is continuously discharged from the water outlet pipe in a pulse water flow mode.
In order to ensure that the impulse water flow generated by the piston pump for the existing tooth flushing device has a considerable water pressure, the interior of the piston pump must have excellent sealing performance, and particularly the sealing performance between the piston and the pump cylinder plays a decisive role. At present, however, the sealing performance between the piston and the pump cylinder in the existing piston pump is mainly realized by the size relationship of the mutual matching of the piston and the pump cylinder and the rubber sealing ring sleeved outside the piston, and the mode can meet the general performance requirements, but is difficult to achieve for equipment needing higher sealing performance; the sealing between piston and the pump cylinder in the piston pump now, the in-process of piston up-and-down motion in the pump cylinder, because of the reason of current piston material and structure, its side easily takes place gas leakage, especially is doing the tensile motion in-process at the piston, and its side easily takes place to admit air to it is not abundant to lead to intaking in the pump cylinder, and has reduced the inside pressure of pump cylinder, and then has reduced the water yield and the water pressure of piston compression drainage, has influenced the result of use.
