The pipeline does not need to be provided with a bottom valve, and only quantitative liquid guiding is required to be ensured to be stored in the pump body before work; different liquids can adopt self-priming pumps made of different materials. A self-priming pump has the working principle that before a water pump is started, a pump shell is filled with water or the water is stored in the pump shell; after the impeller is started, the impeller rotates at a high speed to enable water in the impeller channel to flow to the volute, at the moment, the inlet forms vacuum, the water inlet check valve is opened, and air in the suction pipe enters the pump and reaches the outer edge through the impeller channel.

In one embodiment, as shown in fig. 3 and 6, the second cover 600 is used to be fixed to the driving motor 900 at a position far away from the first cover 500 by a mounting screw 630. Such a design facilitates quick assembly and disassembly of the self-priming pump assembly.

In one embodiment, as shown in fig. 3 and 8, the first fixing member 700 is disposed in the first cover 500, the second fixing member 800 is disposed in the second cover 600, and the first fixing member 700 and the second fixing member 800 are disposed at an interval; in one embodiment, the first fixing member 700 disposed in the first cover 500 and the second fixing member 800 disposed in the second cover 600 are spaced apart from each other by: in a state where the second magnet 810 generates a maximum attractive force to the first magnet 710 and/or a state where the main diaphragm 400 generates a maximum deformation toward a direction approaching the second fixing member 800, a distance between the first fixing member 700 and the second fixing member 800 is at least 1 nm; further, in one embodiment, during the full design life cycle of the self-priming pump assembly or the main diaphragm 400 thereof, the manufacturing error of the main diaphragm 400 is counted and the deformation degree of the main diaphragm 400 during the full design life cycle thereof is estimated, so that the distance between the first fixing member 700 and the second fixing member 800 is at least 1 nm in the state that the second magnet 810 generates the maximum attraction force to the first magnet 710 and the state that the main diaphragm 400 generates the maximum deformation toward the direction close to the second fixing member 800.

In theory, no matter how close the first fixing member 700 is to the second fixing member 800, the first fixing member 700 and the second fixing member 800 may not contact with each other in the working state or even in any state; from the technical realization point of view, generally, the smaller the spacing is, the smaller the product volume is, but due to the deformation error of each main diaphragm 400 and the change of the main diaphragm 400 in the service life process, the smaller the spacing is, the higher the possibility of generating the out-of-control contact is, so the production error of the main diaphragm 400 and the deformation influence of the full design life cycle need to be considered, so that the first fixing member 700 and the second fixing member 800 do not contact, that is, the transmission structure does not generate friction.

In one embodiment, as shown in fig. 3 and 8, the main diaphragm 400 abuts against the compression chamber 300 and the first fixing member 700, respectively; in one embodiment, the main diaphragm 400 is thickened at or adjacent to where it abuts the first fixing member 700; in one embodiment, the main diaphragm 400 is thickened at or adjacent to where it abuts the first fixing member 700; the first cover 500 has at least two first mounting locations 520, the second cover 600 has at least two second mounting locations 620, and the first mounting locations 520 are detachably fixed to the second mounting locations 620 in a one-to-one correspondence manner, so that the first cover 500 and the second cover 600 are fixed together.

In one embodiment, at least two first magnets 710 are circumferentially fixed on the first fixing member 700, and at least two second magnets 810 are circumferentially fixed on the second fixing member 800; in one embodiment, as shown in fig. 11 and 12, each of the second magnets 810 fixed circumferentially by the second fixing member 800 forms at least two magnet groups by position, that is, at least two magnet groups by position, each of the magnet groups includes one, two or more second magnets 810, and a spacer 830 is disposed between two adjacent magnet groups, and an arc of the spacer 830 in the circumferential direction is set according to a frequency of reciprocating deformation of the main diaphragm 400; the first magnets 710 of the first fixing member 700 are arranged in a regular circumferential direction. Further, the magnetic poles of each of the first magnets 710 and each of the second magnets 810 are set as required. In this embodiment, the second fixing member 800 is configured to generate a periodic suction force and a periodic repulsion force on the first magnet 710 through the second magnet 810 in a rotating state, so as to drive the main diaphragm 400 to generate a reciprocating deformation along a rotating axial direction with respect to the compression chamber 300, so as to drive the opening and closing of the one-way water inlet valve 210 and the one-way water outlet valve 220, respectively. Further, in one embodiment, as shown in fig. 3 and fig. 5, the positions of the main diaphragm 400 and the first fixing member 700 are defined by the water inlet and outlet cover 100 and the first cover 500, so that the first fixing member 700 drives the main diaphragm 400 to perform reciprocating deformation along the rotation axis direction relative to the compression chamber 300 under the action of the second fixing member 800. For example, as shown in fig. 3, the main diaphragm 400 deforms downward, the one-way inlet valve 210 opens, water enters from the inlet 111, and the one-way outlet valve 220 closes; the main diaphragm 400 deforms upward, the one-way water outlet valve 220 is opened, the one-way water inlet valve 210 is closed, and self-suction water outlet is realized from the water outlet 121. This is one of the important designs of this application, makes first mounting 700 and second mounting 800 separate each other through magnetic force transform, has consequently overcome transmission structure's friction to greatly avoided traditional transmission structure's mechanical attenuation problem, had the noise little, operating current is low and guarantee advantages such as product life, and contactless transmission has stifled protection effect to the motor.

Further, the first fixing member 700 is provided with an abutting plane at the position where the first fixing member 700 is installed on the protruding pillar 410, so that the second fixing member 800 does not drive the first fixing member 700 to rotate in a rotating state. Such a design is beneficial to ensure that the first fixing member 700 drives the main diaphragm 400 to generate reciprocating deformation along the rotation axis direction relative to the compression chamber 300, that is, when the second fixing member 800 rotates, the first fixing member 700 moves along the rotation axis direction, that is, moves up and down relative to the rotation plane, and the abutting end 720 drives the main diaphragm 400 to generate a certain degree of design deformation back and forth along the rotation axis direction, so as to open the one-way water inlet valve 210 and keep the one-way water outlet valve 220 closed to realize water inlet, or open the one-way water outlet valve 220 and keep the one-way water inlet valve 210 closed to realize water outlet.
