[0002] Electromagnetic water pumps are widely used in household care electrical appliances, such as steam mops, steam irons, steam cleaners, tabletop steam irons, floor washers, etc. However, there are still some problems with existing electromagnetic water pumps during use.

[0003] In the prior art, in the "Electromagnetic Water Pump Protection and Fixing Device" with the authorization publication (announcement) number CN215979851U, a protection and fixing device for an electromagnetic water pump is disclosed. It includes a fixed base, a protective housing, an electromagnetic water pump, and a protective top cover. The protective housing is installed on the fixed base, the electromagnetic water pump is arranged inside the protective housing, the protective top cover is provided at the top of the protective housing, a fixed card slot is installed on the protective top cover, a connection buckle is provided on the fixed base, and a fixed through hole is opened on the protective top cover. The beneficial effects of the present invention are that the protective housing protects the electromagnetic water pump. When the protective housing is collided, the shock-absorbing buffer rod and the buffer spring can play a role in shock absorption and buffering, reducing the impact force, preventing the electromagnetic water pump from being damaged by collision, and improving the service life. The heat generated by the operation of the electromagnetic water pump is conducted to the heat conducting plate, and the heat of the heat conducting plate is conducted to the heat dissipating fins through the heat conducting columns, and the heat is dissipated through the heat dissipating fins, improving the heat dissipation effect, preventing the electromagnetic water pump from being damaged due to overheating, and improving the service life.

[0004] During the operation of the above device, the protective housing protects the electromagnetic water pump, and the protective top cover is detachable and used in conjunction with the shock-absorbing structure for shock absorption. It is easy to cause the device to have an inclined collision, and due to the elastic adjustment, the structure is unevenly stressed, and the shock-absorbing effect is unstable.

[0005] In the prior art, in the "A Fixing Device for an Electromagnetic Water Pump Facilitating Maintenance" with the authorized publication number CN216044384U, the present utility model discloses a fixing device for an electromagnetic water pump facilitating maintenance, including a fixed base, a fixed mounting frame, a protective housing, and an electromagnetic water pump. A fixed mounting frame is installed on the top of the fixed base, a protective housing is provided on the fixed base, and an electromagnetic water pump is provided inside the protective housing. One end of the electromagnetic water pump is provided with a water suction pipe, and the water suction pipe penetrates through the protective housing and extends out of one side of the protective housing. The electromagnetic water pump is provided with a water outlet pipe, and the water outlet pipe penetrates through the protective housing and extends out of one side of the top of the protective housing. The beneficial effects of the present utility model are that the protective housing and the electromagnetic water pump are convenient for installation and disassembly, facilitating the later maintenance and repair of the electromagnetic water pump, which can effectively shock-absorb and buffer the impact force, play a protective role for the water pump, prevent the water pump from being damaged, and improve the service life. Heat dissipation is carried out through heat dissipation through holes and a heat dissipation fan, enabling the air inside the protective housing to flow, improving the heat dissipation effect, and preventing the device from being damaged due to overheating;

[0006] During the operation of the above device, the electromagnetic water pump is fixed by fixing bolts and buffer springs, which is convenient for installation, disassembly, and later maintenance and repair. Heat dissipation is carried out through heat dissipation through holes and a heat dissipation fan, enabling the air inside the protective housing to flow, improving the heat dissipation effect, and preventing the device from being damaged due to overheating.
