Abstract

The invention discloses a pressure relief structure, a booster pump and water purification equipment. The pressure relief structure comprises a pressure relief cavity shell and a pressure relief cover, wherein a pressure relief cavity is defined by the pressure relief cavity shell in an enclosed mode, and the pressure relief cavity shell is provided with a pressure relief opening communicating with the pressure relief cavity; and the pressure relief cavity shell is covered with the pressure relief cover, a sealing part is arranged between the pressure relief cover and the cavity wall of the pressure relief cavity, the sealing part surrounds the pressure relief opening, the pressure relief cover is further provided with a pressure relief gasket, and the pressure relief opening is blocked or opened by the pressure relief gasket. According to the technical scheme, the sealing capacity and pressure stabilizing capacity of the pressure relief structure of the booster pump can be improved.

Description

technical field [0001] The invention relates to the technical field of booster pumps, in particular to a pressure relief structure, a booster pump using the pressure relief structure and water purification equipment using the booster pump. Background technique [0002] At present, booster pumps are components that power electrical appliances such as water purifiers in the mainstream water purification market. The booster pump changes the pressure of the water source through the design of the internal high and low pressure chambers, thereby achieving the purpose of boosting the water source. In order to prevent the pressure of the water source from the booster pump from being too high, resulting in the bursting of the connected water pipe and other adverse conditions, the booster pump is also designed with a pressure relief structure. The high and low pressure chambers of the pump are connected to relieve pressure. [0003] Existing booster pumps generally use pressure reli...
