Embodiment

[0026] like figure 1 As shown, this embodiment provides a miniature diaphragm water pump with overload protection, including a pump body 1, the water inlet end of the pump body 1 is connected to the water inlet pipe 2, and the water outlet end of the pump body 1 is connected to the water outlet pipe 3. The outlet pipe 3 is provided with a first through hole, the first through hole is connected with a first closing plate 4, the first closing plate 4 is in contact with the side wall of the first through hole, and the first closing plate 4 is in contact with the first through hole. The side walls of the through holes are sealed and connected by waterproof glue.

[0027] When the pipeline of the end product is blocked, the water pump is still working normally. At this time, it will cause a lot of wear to the diaphragm and transmission parts of the water pump, and may even cause the diaphragm to rupture, bringing safety hazards. In this embodiment, a first through hole is set on t...

Abstract

The invention discloses a miniature diaphragm water pump with an overload protection function, which comprises a pump body, a water inlet end of the pump body is connected with a water inlet pipe, a water outlet end of the pump body is connected with a water outlet pipe, a first through hole is arranged on the water outlet pipe, a first sealing plate is connected to the first through hole, the first sealing plate makes contact with the side wall of the first through hole, and the first sealing plate is hermetically connected with the side wall of the first through hole through waterproof glue. The device can prevent a diaphragm and a transmission part in the pump body from being greatly damaged when a pipeline in a terminal product is blocked.

Description

technical field [0001] The invention relates to the technical field of water pumps, in particular to a miniature diaphragm water pump with overload protection. Background technique [0002] Definition of micro water pump: any composition form is motor + pump body, and there are two interfaces on the pump body, one inlet and one outlet. Water enters from the water inlet and outlet from the drain. It's called a micro pump. [0003] According to the internal structure, micro-pumps can be divided into: diaphragm type, rotary vane type (impeller type), piston type (plunger type), etc. At present, micro-diaphragm water pumps are widely used in daily life. The existing problems of micro-diaphragm water pumps are , When the pipeline of the end product is blocked, the water pump is still working normally. At this time, it will cause a lot of wear to the diaphragm and transmission parts of the water pump, and may even cause the diaphragm to rupture, bringing safety hazards. Content...
