Problems solved by technology

[0004] Therefore, in the application scenario of an instant water dispenser such as a high-level water tank, the check valve 23 is subject to the pressure of the high-pressure water tank, which is prone to water dripping; Due to the suction effect of the high-pressure water tank, it is easy to produce backflow phenomenon

Abstract

The invention relates to a water pump. The water pump comprises an upper pump body, a lower pump body and a driving motor, a water inlet and a water outlet with the same axis direction as the drivingmotor are formed in the upper pump body, a pressurizing water cavity is formed in the lower pump body, the driving motor is connected with the pressurizing water cavity in a driven mode, and a water stopping assembly is arranged between the upper pump body and the lower pump body; and the water stopping assembly comprises a water way plate forming a water outlet cavity and a high-pressure cavity,the upper pump body and a sealing gasket forming a balance cavity. During working of the water pump, water enters from the water inlet, and flows out of the pressurizing cavity, the high-pressure cavity and the water outlet cavity in sequence to the water outlet to achieve water supply, once the water pump is stopped, the sealing gasket immediately cuts off the high-pressure cavity and the water outlet cavity, under the effect of the balance cavity, the gasket only needs the appropriate spring force so that cutting of the high-pressure cavity and the water outlet cavity is kept, and dripping or back flowing at the water outlet is prevented.

Description

technical field [0001] The invention relates to a water pump, in particular to a water pump used in a water dispenser. Background technique [0002] Instant water dispensers on the market mainly include high-level water tanks (such as figure 1 shown), and the low level tank type (such as figure 2 shown), they are all connected by a water tank 21, a water pump 22, a one-way valve 23, a heater 24, and a water outlet device 24. [0003] One-way valve 23 is used for water pump 22 to stop working, plays the effect of interception, anti-backflow, and one-way valve 23 sealing water force is determined by the elastic force of the spring of its inside setting, and prior art one-way valve 23 is simultaneously Commonly used in these two types of instant water dispensers, therefore, the elastic force of the spring force should be as small as possible under the conditions of water sealing and water flow, which can effectively reduce the power of the water pump 22 and reduce the temper...
