High-reliability miniature water pump with flow stopping function

Abstract

The invention discloses a high-reliability miniature water pump with a flow stopping function. The miniature water pump comprises an upper cover, a bottom cover, a cylinder body and a valve plate, wherein the bottom cover is connected to the upper cover, and the cylinder body and the valve plate are arranged between the upper cover and the bottom cover; a driving motor is arranged on the other side, opposite to the upper cover, of the bottom cover, and a motor mounting groove allowing the driving motor to be embedded is formed in the lower part of the bottom cover in an integral forming mode;a pair of leather cup bodies used for realizing liquid pumping through compression and expansion are arranged between the valve plate and the cylinder body; an output shaft of the driving motor is connected to an eccentric wheel, and a T-shaped swing frame is arranged on the eccentric wheel; and the upper parts of the leather cup bodies are in a bowl shape, and the lower parts of the leather cup bodies are connected to connecting rods used for being connected to the swing frame. According to the high-reliability miniature water pump with the flow stopping function, through grooves used for penetrating through the leather cup bodies are correspondingly formed in the cylinder body, in the actual use process, the coordination of a flow stopping valve and a spring body can better avoid the siphon phenomenon when a product stops pumping water, the use reliability and the actual use effect of the product are improved, the structural design of the water pump is reasonable, and the water pumpis suitable for wide-range popularization and application.

Description

[technical field] [0001] The invention relates to the technical field of water pump products, in particular to a high-reliability micro-water pump with a reasonable structural design and a good use effect with its own flow-stopping function. [Background technique] [0002] Micro water pump is a relatively common product in the field of liquid transmission. It is small in size and compact in structure, and can play a vital role in many occasions.
