Electromagnetic vibration pump with non-return ventilation valve

Abstract

The invention relates to an electromagnetic vibration pump with a non-return breather valve. The electromagnetic vibration pump comprises an electromagnetic vibration pump body; a water outlet end thereof is connected with a water outlet connection pipe. A check valve which prevents high pressure gas from reflowing is arranged at the position of a water outlet end where the water outlet connection pipe and a high pressure device are connected. A breather valve is arranged at a pipe body of the water outlet connection pipe. A cavity is arranged in a valve body of the breather valve. One end of the cavity is communicated with a pipe cavity communication opening of the water outlet connection pipe, and the other end of the cavity is communicated with a venthole which is communicated with outside air. The size of the section of the venthole is less than the size of the section of the cavity. The cavity is internally equipped with a breather valve core which can jump. The breather valve core coordinates with the venthole. The electromagnetic vibration pump uses the theory that the electromagnetic vibration ensures that electromagnetic vibration causes the breather valve to jump to realize the ventilation and ensure that the electromagnetic vibration pump has self-absorption function, thereby saving traditional elastic parts, improving the efficiency of mass production and reducing the cost of the product.

Description

technical field [0001] The invention relates to the technical field of related components used in electromagnetic water pumps, in particular to an electromagnetic vibrating pump with a check valve. Background technique [0002] At present, electromagnetic vibrating pumps have been widely used in various fields, especially miniature plunger pumps have been widely used for their compact and precise structure, such as in coffee machines, steam generators and other products. Ordinary electromagnetic vibrating pumps can self-prime and pump water when there is no reverse pressure. However, in some occasions, electromagnetic vibrating pumps often have to bear a lot of reverse pressure. In order to prevent high-pressure backflow, a check valve is generally installed on the outlet end of the water outlet connection pipe. At this time, if the electromagnetic vibration pump is turned on, the air pressure pumped in the electromagnetic vibration pump cannot overcome the external high-pre...

Ordinary electromagnetic vibrating pumps can self-prime and pump water when there is no reverse pressure. However, in some occasions, electromagnetic vibrating pumps often have to bear a lot of reverse pressure. In order to prevent high-pressure backflow, a check valve is generally installed on the outlet end of the water outlet connection pipe. At this time, if the electromagnetic vibration pump is turned on, the air pressure pumped in the electromagnetic vibration pump cannot overcome the external high-pressure gas. Pressure on the check valve so there is not enough self-priming capacity to pump water out
