[0022] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0023] like Figure 1 As shown, a power cord sealing structure of a pump includes a plastic seat 1 and a power cord 4, the outer side of the power cord 4 is wrapped with a sheath 5, and also includes a support plate 2 and soft glue 3; the plastic seat 1 is fixedly connected to the power cord 4 passing through the plastic seat 1, and the plastic seat 1 is wrapped with a support plate 2 for supporting the plastic seat, and the space between the plastic seat 1 and the sheath of the power cord 4 is filled with soft glue 3.

[0024] Optionally, the plastic seat 1 and the support plate 2 are integrally formed by injection molding.

[0025] Optional, such as Figure 3 As shown, a plastic seat through hole 11 is opened at the center of the plastic seat 1.

[0026] Optional, such as Figure 2As shown, a boss that contracts towards the center is provided on one side of the plastic base 1, and fixing holes are provided at the edges of the other flat side of the plastic base 1. It is fixed to the fixing plate 7 through fasteners in the fixing holes.

[0027] Optionally, the plastic base 1 is made of a PVC plastic base. The thermoplastic plastic base 1 meets the technical conditions QJ167A - 1995.

[0028] Optionally, a support plate through - hole (not shown) corresponding to the through - hole of the plastic base is provided at the center of the support plate 2. The support plate 2 is made of a rigid material, and the rigid material is specifically a steel plate or other metal to prevent the plastic base from deforming and causing seal failure.

[0029] Optionally, the soft glue 3 is placed inside the connection between the plastic base 1 and the power cord 4, and the soft glue is an injection - molded soft glue.

[0030] Optionally, as Figure 4 shown, an interference fit is provided between the plastic base 1 and the power cord 4. The power cord 4 is composed of multiple - strand wire bundles. Each wire bundle of the power cord 4 is connected with a wire - harness terminal 6. The other end of the power cord is connected with a plug for connecting to a power supply. The conductor of the power cord is copper wire, aluminum wire or other metal wires. This power cord meets the requirements of IEC60227 and IEC60335 standards; the wire - harness terminal is provided with an insulating sheath.
