In order to better explain the mounting relationship of the electrode mount 100 with other components in the present embodiment, the structure of the electrode mount 100 is described in detail below.
As shown in fig. 10 to 12, the electrode mount 100 includes an insulating housing 110, and a first receiving chamber 120 for mounting a disc electrode 200, a second receiving chamber 130 for mounting a ball electrode 300, and a third receiving chamber 140 for mounting a power supply shaft (i.e., a power supply shaft receiving chamber) are provided in the insulating housing 110, and the first receiving chamber 120 and the second receiving chamber 130 are disposed at a distance and communicate through the third receiving chamber 140. One end of the third accommodating chamber 140 penetrates through the lower end of the insulating base 110, the first accommodating chamber 120 is arranged at the upper end of the third accommodating chamber 140, and the second accommodating chamber 130 is arranged around the periphery of the third accommodating chamber 140. The insulating housing 110 is further provided with a first terminal hole 121 communicating with the first accommodating chamber 120 and a second terminal hole 131 communicating with the second accommodating chamber 130. The first connection terminal 210 (i.e., the connection terminal of the disc electrode 200) and the second connection terminal 310 (i.e., the connection terminal of the ball electrode 300) pass through the first connection terminal hole 121 and the second connection terminal hole 131, respectively, and then protrude out of the electrode mount 100 to electrically connect to an external power supply device. More specifically, the first and second terminal holes 121 and 131 may be located at the same side of the insulating housing 110 so as to be wired with an external power supply device also mounted to the fixing member.
The insulating housing 110 may be mounted on a fixed member, such as a cabinet of an air conditioner. The insulating base 110 may be integrally formed of an insulating material such as rubber. The first receiving chamber 120 may directly use the top space of the third receiving chamber 140, and the disc electrode 200 may be placed from the lower opening of the third receiving chamber 140 due to the certain elasticity of the insulating holder 110, and finally be clamped at the top of the third receiving chamber 140. Similarly, the ball electrode 300 may be placed from the lower end opening of the third accommodating chamber 140 and finally clamped in the second accommodating chamber 130.
As shown in fig. 10 to 12, the insulating housing 110 is composed of a plurality of cylinders having sequentially increasing diameters. Further, the insulating housing 110 includes a first cylinder 111, a second cylinder 112 and a third cylinder 113 having sequentially increasing diameters, and an annular groove 150 is formed between the second cylinder 112 and the third cylinder 113 in a radially inward concave shape. Annular groove 150 may be adapted to the annular protrusion on the fixed member to further enable insulating housing 110 to be positioned and mounted on the fixed member more accurately to prevent axial displacement.
Further, as shown in fig. 10 and 11, the side of the annular groove 150 adjacent to the second cylinder 112 is provided with an annular flange 151. By providing the annular flange 151, the heights of the two sides of the annular groove 150 can be similar or equal, so that insufficient depth of the annular groove 150 due to the diameter difference between the second cylinder 112 and the third cylinder 113 is avoided, and the positioning stability is improved.
Further, as shown in fig. 10 and 11, the outer wall of the second cylinder 112 is provided with a plurality of outwardly convex first ribs 160 in the circumferential direction, and the outer wall of the third cylinder 113 is provided with a plurality of outwardly convex second ribs 170 in the circumferential direction. Specifically, the first ribs 160 and the second ribs 170 may be cylindrical ribs extending along the axial direction of the second cylinder 112, and accordingly, the first ribs 160 and the second ribs 170 may be adapted to the recesses on the fixing member, thereby preventing the insulation base 110 from being rotationally displaced. Further, the first ribs 160 and the second ribs 170 may be uniformly distributed at equal intervals along the circumferential direction, so that the stress of the insulating base 110 is more uniform. Meanwhile, the first ribs 160 and the second ribs 170 may be disposed at a different position from each other.
Further, as shown in fig. 11 and 12, the end surface of the third cylinder 113 facing away from the second cylinder 112 is provided with a plurality of grooves 180 recessed inward in the axial direction. In particular, the grooves 180 may be uniformly distributed along the circumference of the third cylinder 113. By arranging the groove 180, vortex airflow can be formed in the groove 180 when the cross-flow fan rotates, and the vortex airflow collides with airflow generated by an impeller of the cross-flow fan, so that the direction of the impeller airflow is changed, the impeller airflow is prevented from striking a volute tongue, airflow noise is generated, and the sound quality of the air conditioner is improved.

When in use, the spherical electrode 300 and the disk electrode 200 are embedded in the electrode mounting seat 100 together to form a positive electrode pair, the electrode mounting seat 100 can be fixed on a casing of an air conditioner, the power supply shaft 400 rotating together with the through-flow fan 700 is inserted into the electrode mounting seat 100 as a fixing part, the inner electrode shaft 421 is rotatably and electrically contacted with the disk electrode 200, the outer electrode shaft sleeve 422 is rotatably and electrically inserted into the columnar through hole 321 of the spherical electrode 300, and then the electric energy of external power supply equipment is transmitted to the rotating motor 500 rotating together with the through-flow fan 700.
