To better explain the mounting relationship of the electrode mount 100 to other components in this embodiment, the structure of the electrode mount 100 will be described in detail below.
As shown in fig. 10 to 12, the electrode mounting base 100 includes an insulating base body 110, a first accommodating cavity 120 for mounting the disk electrode 200, a second accommodating cavity 130 for mounting the ball electrode 300, and a third accommodating cavity 140 (i.e., a power supply shaft accommodating cavity) for mounting the power supply shaft are disposed in the insulating base body 110, and the first accommodating cavity 120 and the second accommodating cavity 130 are disposed at an interval and are communicated with each other through the third accommodating cavity 140. One end of the third accommodating cavity 140 penetrates through to the lower end of the insulating base 110, the first accommodating cavity 120 is disposed at the upper end of the third accommodating cavity 140, and the second accommodating cavity 130 surrounds the periphery of the third accommodating cavity 140. The insulating base 110 further defines a first connection terminal hole 121 communicating with the first accommodating cavity 120 and a second connection terminal hole 131 communicating with the second accommodating cavity 130. The first connection terminal 210 (i.e., the connection terminal of the disc-shaped electrode 200) and the second connection terminal 310 (i.e., the connection terminal of the ball-shaped electrode 300) respectively pass through the first connection terminal hole 121 and the second connection terminal hole 131 and then extend out of the electrode mount 100 to electrically connect to an external power supply. More specifically, the first and second terminal holes 121 and 131 may be located at the same side of the insulation housing 110 so as to be wired with an external power supply device also mounted to the fixing part.
The insulation housing 110 may be installed on a fixed part, such as a cabinet of an air conditioner. The insulation base 110 may be integrally formed by using an insulation material such as rubber. The first accommodating cavity 120 can directly use the top space of the third accommodating cavity 140, and the disk-shaped electrode 200 can be put into the lower opening of the third accommodating cavity 140 and finally clamped on the top of the third accommodating cavity 140 due to the elasticity of the insulating base 110. Similarly, the ball electrode 300 can be inserted into the lower opening of the third accommodating cavity 140 and finally clamped in the second accommodating cavity 130.
As shown in fig. 10 to 12, the insulation housing 110 is composed of a plurality of cylinders with gradually increasing diameters. Furthermore, the insulation base 110 includes a first cylinder 111, a second cylinder 112 and a third cylinder 113 with increasing diameters, and an annular groove 150 is formed between the second cylinder 112 and the third cylinder 113 along the radial direction. The annular groove 150 can be matched with the annular protrusion on the fixing component, so that the insulation seat body 110 can be positioned and installed on the fixing component more accurately, and axial displacement is prevented.
Further, as shown in fig. 10 and 11, the annular groove 150 is provided with an annular flange 151 on a side thereof adjacent to the second cylindrical body 112. The heights of the two sides of the annular groove 150 can be close to or equal by arranging the annular flange 151, so that the insufficient depth of the annular groove 150 caused by the diameter difference of the second cylinder 112 and the third cylinder 113 is avoided, and the stability of positioning is improved.
Further, as shown in fig. 10 and 11, the outer wall of the second cylinder 112 is provided with a plurality of first ribs 160 protruding outward in the circumferential direction, and the outer wall of the third cylinder 113 is provided with a plurality of second ribs 170 protruding outward in the circumferential direction. Specifically, the first rib 160 and the second rib 170 may be cylindrical ribs extending along the axial direction of the second cylinder 112, and accordingly, the first rib 160 and the second rib 170 may be adapted to the concave portion on the fixing component, so as to prevent the insulation base 110 from rotating and shifting. Furthermore, the first ribs 160 and the second ribs 170 may be evenly distributed along the circumferential direction at equal intervals, so that the stress on the insulation base 110 is more even. Meanwhile, the first ribs 160 and the second ribs 170 may be disposed to be offset from each other.
Further, as shown in fig. 11 and 12, an end surface of the third cylinder 113 facing away from the second cylinder 112 is provided with a plurality of axially concave grooves 180. Specifically, the grooves 180 may be uniformly distributed along the circumference of the third cylinder 113. By arranging the groove 180, when the cross flow fan rotates, vortex air flow can be formed in the groove 180, the vortex air flow collides with air flow generated by an impeller of the cross flow fan, the direction of the impeller air flow is changed, the phenomenon that the impeller air flow strikes a volute tongue to generate air flow noise is avoided, and the sound quality of the air conditioner is improved.
It can be seen from the above embodiments that, in the spherical electrode 300, the motor and the air conditioner provided by the present invention, the spherical electrode 300 is clamped on the inner wall surface and the outer wall surface of the insulating sphere 320 by the conductive clamp 330 formed by the inner conductive sheet 331 and the outer conductive sheet 332 connected at one end, the spherical electrode 300 can be clamped in the fixed component by the outer conductive sheet 332, meanwhile, the outer conductive sheet 332 can be electrically connected to the external power supply device, the inner conductive sheet 331 can be in rotational contact with the power supply shaft, so that the electric energy of the external power supply device fixedly installed can be transmitted to the rotating component. When in use, the spherical electrode 300 and the disc-shaped electrode 200 are embedded in the electrode mounting seat 100 together to form a positive and negative electrode pair, the electrode mounting seat 100 can be fixed on a shell of an air conditioner to be used as a fixing part, meanwhile, the power supply shaft 400 rotating together with the cross flow fan 700 is inserted into the electrode mounting seat 100, the inner electrode shaft 421 can be rotatably and electrically abutted against the disc-shaped electrode 200, the outer electrode shaft sleeve 422 can be rotatably and electrically inserted into the columnar through hole 321 of the spherical electrode 300, and further, the electric energy of external power supply equipment is transmitted to the rotating motor 500 rotating together with the cross flow fan 700. The spherical electrode 300 and the motor are simple in structure, stable power supply from a fixed end to a rotating end is achieved, the rotating motor 500 can output another path of rotating motion to drive corresponding parts to complete extra rotating motion while rotating in a follow-up mode, and the working stability and reliability of the rotating motor 500 are improved.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
