[0019] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the accompanying drawings. Figure 1 , Figure 2 and Figure 3As shown, a diaphragm electromagnetic pump 10 includes a diverter component 100 and an electromagnetic drive component 200. The diverter component 100 includes a connecting cover 110 and a diverter plate 120. The diverter plate 120 is arranged in the connecting cover 110. The connecting cover 110 is provided with an inlet channel 111 and an outlet channel 112. The diverter plate 120 is provided with a diverter channel 121. The diverter channel 121 is connected to the inlet channel 111 and the outlet channel 112 respectively; the electromagnetic drive component 200 includes an electromagnetic module 210 and a pressure-resistant and corrosion-resistant diaphragm 220. The electromagnetic module 210 is connected to the connecting cover 110. The pressure-resistant and corrosion-resistant diaphragm 220 is arranged between the electromagnetic module 210 and the diverter plate 120. A telescopic end 211 is provided on the electromagnetic module 210. One end of the pressure-resistant and corrosion-resistant diaphragm 220 is connected to the telescopic end 211, and the other end of the pressure-resistant and corrosion-resistant diaphragm 220 abuts against the diverter plate 120.

[0020] It should be noted that the electromagnetic drive component 200 is composed of a bracket, a coil, an iron core and a spring. The spring is arranged inside the bracket, one end of the iron core is connected to the spring, and the other end of the iron core is connected to the pressure-resistant and corrosion-resistant diaphragm 220 as the telescopic end 211 of the electromagnetic module 210. The coil is arranged outside the bracket. When the coil is energized, the iron core performs telescopic movement according to the principle of electromagnetic action and the elastic action of the spring, thereby driving the pressure-resistant and corrosion-resistant diaphragm 220 to perform the pump body piston movement, so that the fluid can flow in the water inlet channel 111, the diversion channel 121 and the water outlet channel 112. Specifically, the water inlet channel 111 and the water outlet channel 112 of the connection cover 110 are respectively located at positions corresponding to the electrical products. When liquid enters from the water inlet channel 111, the electromagnetic module 210 drives the pressure-resistant and corrosion-resistant diaphragm 220 to perform piston movement, so that negative pressure is formed between the pressure-resistant and corrosion-resistant diaphragm 220 and the diverter plate 120, thereby allowing the liquid to enter the diverter channel 121 from the water inlet channel 111, and then enter the water outlet channel 112 from the diverter channel 121. Since the pressure-resistant and corrosion-resistant diaphragm 220 has good pressure resistance and corrosion resistance, it can be used for a long time without deformation or damage, thereby providing a longer service life and flow stability of the electromagnetic pump, and improving the quality of the product. In the present embodiment, the pressure-resistant and corrosion-resistant diaphragm 220 is an EPDM rubber diaphragm, so that the diaphragm electromagnetic pump 10 has good aging resistance, which can improve the service life of the pump body as a whole, and the EPDM rubber diaphragm has good chemical corrosion resistance, which makes the pump body more applicable to household appliances. At the same time, the application of the EPDM rubber diaphragm makes the overall pump body structure have good heat resistance, acid and alkali resistance, water vapor resistance and other properties, and can be used in household appliances such as steam irons and coffee machines that require high temperature operation, thereby improving the overall quality of the product. The diaphragm electromagnetic pump 10 of the utility model adopts the pressure-resistant and corrosion-resistant diaphragm 220 to be in direct contact with the fluid, so that the overall pump body structure has good water vapor resistance, corrosion resistance and other properties, and has good pressure resistance and anti-deformation properties, so that the service life of the electromagnetic pump is improved, and it has good stability.

[0021] In one embodiment, if Figure 1 As shown, the pressure-resistant and corrosion-resistant diaphragm 220 is provided with a clamping end 221, and the clamping end 221 is connected to the telescopic end 211, so that the pressure-resistant and corrosion-resistant diaphragm 220 can be fixed on the telescopic end 211 of the electromagnetic module 210, so that the pressure-resistant and corrosion-resistant diaphragm 220 is driven by the electromagnetic module 210 to perform piston movement; for another example, the water inlet channel 111 and the water outlet channel 112 are both provided with a check valve 113, so that by providing the check valve 113, the fluid in the water inlet channel 111 and the water outlet channel 112 will not flow back, thereby making the flow accuracy of the electromagnetic pump higher and more stable.

[0022] Combination Figure 2 and Figure 3 As shown, in one embodiment, an abutting convex ring 222 is provided at one end of the pressure-resistant and corrosion-resistant diaphragm 220 close to the diverter disk, and an abutting mounting groove 122 is provided on the diverter disk 120, and the abutting convex ring 222 is arranged in the abutting mounting groove 122. In this way, the pressure-resistant and corrosion-resistant diaphragm 220 can be installed in the abutting mounting groove 122 of the diverter disk 120 through the abutting convex ring 222, so that a sealed space is formed between the pressure-resistant and corrosion-resistant diaphragm 220 and the diverter disk, thereby driving the fluid to move under the piston movement of the pressure-resistant and corrosion-resistant diaphragm 220; for another example, a sealing convex surface 223 is provided at one end of the pressure-resistant and corrosion-resistant diaphragm 200 close to the diverter disk 120, and the sealing convex surface 223 is located in the abutting convex ring 222, and the sealing convex surface 223 is aligned with the diverter channel 121 The liquid outlet is abutted or separated. In this way, when the sealing convex surface 223 is abutted against the liquid outlet of the shunt channel 121, the water outlet channel 112 is in a blocked state, and the fluid cannot enter the water outlet channel 112. When the sealing convex surface 223 is separated from the liquid outlet of the shunt channel 121, the water outlet channel 112 is in a flowing state, so that the fluid can enter the water outlet channel 112 and flow out from the water outlet channel 112; for example, anti-sticking knife patterns are provided on the sealing convex surface, so that the anti-sticking property of the sealing convex surface can be improved, and the sealing convex surface can be prevented from adhering to the liquid outlet of the shunt channel 121 after long-term use, or the sealing convex surface and the liquid outlet of the shunt channel 121 are made sticky, thereby increasing the service life of the pump body and improving the flow accuracy and stability.

[0023] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
