Embodiment 1

[0035] refer to Figure 1 to Figure 3 As shown in , the non-return body assembly provided by this embodiment is applied in the electromagnetic pump. The electromagnetic pump is composed of a working chamber and a liquid outlet chamber arranged in front and back, and a liquid flow hole connecting the two, and the working chamber is movable. The pump core 12; the non-return body assembly includes:

[0036] The first non-return body 1 can be accommodated axially in the liquid outlet cavity and has a first sealing body 5 at the front end. The first non-return body 1 is also provided with a mounting hole penetrating to the front end surface;

[0037] The first spring 3 is arranged in the liquid outlet chamber to urge the first non-return body 1 to reset, and the first non-return body 1 closes the rear opening of the liquid flow hole;

[0038] The non-return member, the front end and the pump core 12 form a valve that allows the water flow to pass through in one direction from fron...

Embodiment 2

[0048] refer to Figure 4 to Figure 6 As shown in , the anti-blocking electromagnetic pump provided by this embodiment includes a main body, wherein the main body is also provided with a non-return body assembly as described in the first embodiment above, so that the non-return body assembly and the pump core seat can be solved conveniently and reliably. The problem of adhesion between 15 and the problem of dirt blocking the liquid flow hole, and the overall structure is simple and reliable, and the production and maintenance costs are greatly reduced.

[0049] In a preferred embodiment, specifically as Figure 5 and Figure 6 As shown in , the main body includes a metal tube 8, a coil 9 sheathed on the outer circumference of the metal tube 8, a coil overmolding 16 covering the outer circumference of the coil 9, a magnetic conductor 10 arranged outside the coil overmolding 16, and a magnetic conductor 10 arranged on the outer circumference of the coil 9. The pump casing 14 o...

Abstract

The invention discloses a non-return body assembly applied to an electromagnetic pump and the anti-blocking electromagnetic pump. The electromagnetic pump comprises a main body and the non-return bodyassembly, wherein a working cavity, a liquid outlet cavity and a liquid flow hole communicating with the working cavity and the liquid outlet cavity are formed in the main body; and a pump core is arranged in the working cavity. The non-return body assembly comprises a first non-return body, a first spring and a non-return component, wherein the front end of the first non-return body is providedwith a first sealing body and a mounting hole; the first spring is used for promoting the first non-return body to reset; and at least one part of the non-return component penetrates through the liquid flow hole, the two ends of the non-return component abut against the pump core and the first non-return body correspondingly, and at least one part of the non-return component stretches into the mounting hole and is used for pushing the first non-return body to move backwards and exposing a rear side opening of the liquid flow hole when the pump core moves backwards. According to the technical scheme, the adhesion problem between the non-return body assembly and a pump core seat and the problem that the liquid flow hole is blocked by dirt can be conveniently and reliably solved, the overallstructure is simple and reliable, and the production and maintenance cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of electromagnetic pumps, in particular to a non-return body assembly used in electromagnetic pumps and an anti-blocking electromagnetic pump. Background technique [0002] The electromagnetic pump is a kind of liquid pump that directly combines the power and the pump body. It mainly generates magnetic induction after the electromagnetic coil is energized, so that the movable pump core generates electromagnetic oscillations, forming a vacuum in the piston cavity, and the one-way valve in the piston cavity is opened. The return spring drives the movable core to perform reciprocating periodic vibrations to pump water. This type of electromagnetic pump has the characteristics of simple structure, light volume, and beautiful appearance, and is widely used in water supply devices for various small household appliances such as electric irons, coffee machines, and cleaning machines. [0003] In practical applicati...
