[0038] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings.

[0039] According to some embodiments of the present invention, referring to Figures 1 to 4The motor with an insulating structure includes a housing 100, a chassis 200 and an insulating fixing member 300. The housing 100 is opened downward, and the lower end of the housing 100 extends in a direction away from the axis of the housing 100 to form a ring portion 110. The ring portion 110 is provided with a plurality of first through holes 111. The chassis 200 is located below the housing 100, and the upper end surface of the chassis 200 abuts against the lower end surface of the ring portion 110 to block the opening of the housing 100, and the chassis 200 is provided with a plurality of second through holes 201. The plurality of first through holes 111 are distributed circumferentially along the axis of the housing 100, and the plurality of second through holes 201 are distributed circumferentially along the axis of the chassis 200, and the housing 100 and the chassis 200 are coaxially arranged. The plurality of insulating fixings 300, the plurality of first through holes 111 and the plurality of second through holes 201 correspond one to one. The insulating fixing 300 includes a first fixing 310, a second fixing 320 and a bolt 340. The first fixing 310 and the second fixing 320 are both made of insulating plastic. The first fixing 310 is located above the ring portion 110, and the lower end surface of the first fixing 310 abuts against the ring portion 110. The second fixing 320 is located below the chassis 200, and the upper end surface of the second fixing 320 abuts against the chassis 200. The first fixing 310 is provided with a first threaded hole 311, and the second fixing 320 is provided with a second threaded hole 321. The bolt member 340 is simultaneously penetrated through the first through hole 111 and the second through hole 201, and is simultaneously threadedly connected to the first threaded hole 311 and the second threaded hole 321. There is a gap between the bolt member 340 and the inner wall of the first through hole 111, and there is a gap between the bolt member 340 and the inner wall of the second through hole 201, so as to prevent the bolt member 340 from abutting against the hole walls of the first through hole 111 and the second through hole 201 to transfer electrons.

[0040] It is understandable that the bolt member 340 passes through the first threaded hole 311, the first through hole 111, the second through hole 201 and the second threaded hole 321 from top to bottom, and the bolt member 340 does not abut against the hole wall of the first through hole 111 and the hole wall of the second through hole 201. The bolt member 340 is used to connect with the volute component 400. The insulating fixing member 300 can isolate the housing 100 and the volute component 400 from each other to prevent the housing 100 from leaking electricity and transferring electricity to the volute component 400.

[0041] Preferably, the aperture of the first threaded hole 311 is smaller than that of the first through hole 111 and the second through hole 201, and the bolt member 340 is threadedly connected to the first threaded hole 311 and the second threaded hole 321 at the same time, thereby preventing the bolt member 340 from abutting against the hole walls of the first through hole 111 and the second through hole 201 to transfer electrons.

[0042] Preferably, refer to Figure 2 and Figure 4The second fixing member 320 is provided with a boss 322, which is upwardly penetrated through the second through hole 201 and the first through hole 111, and the boss 322 is provided with a second threaded hole 321, and the upper end of the boss 322 abuts against the first fixing member 310. It can be understood that the boss 322 can separate the bolt member 340 from the hole wall of the first through hole 111, and separate the bolt member 340 from the hole wall of the second through hole 201. It is prevented that the bolt is charged due to contact with the chassis 200 or the ring portion 110.

[0043] Preferably, refer to Figure 2 and Figure 4 The second fixing member 320 is provided with a rim portion 330 on the side away from the axis of the chassis 200, the upper end of the rim portion 330 abuts against the first fixing member 310, and the side of the rim portion 330 close to the axis of the chassis 200 abuts against the outer side of the ring portion 110 and the outer side of the chassis 200. The rim portion 330 can fit the outer sides of the chassis 200 and the ring portion 110 to prevent accidental contact with the ring portion 110 and the chassis 200.

[0044] Preferably, refer to Figure 3 A plurality of latching members 220 are provided on the outer side of the chassis 200, and the plurality of latching members 220 cooperate together to limit the horizontal movement of the ring portion 110. It can be understood that when the shell 100 is placed downwardly on the upper side of the chassis 200, the ring portion 110 is attached to the chassis 200, and the plurality of latching members 220 circumferentially surround the ring portion 110 around the axis of the chassis 200, thereby limiting the movement of the ring portion 110 to play a positioning role.

[0045] Further, see Figure 3 The outer side of the ring portion 110 is provided with a plurality of first lugs 112, the first lugs 112 are provided with a first through hole 111, the outer side of the chassis 200 is provided with a plurality of second lugs 240, the second lugs 240 are provided with a second through hole 201, and the first lugs 112 and the second lugs 240 can facilitate the processing of the first through hole 111 and the second through hole 201. The edge portion 330 can surround the first lug 112 and the second lug 240, so that the motor with an insulating structure is more likely to touch the edge portion 330 first when moving horizontally to avoid leakage.

[0046] Preferably, refer to Figure 3 and Figure 4 A driving component 120 is disposed in the housing 100 , a through hole 230 is disposed in the middle of the chassis 200 , and a rotating shaft 121 of the driving component 120 passes through the through hole 230 and is rotatably connected to the housing 100 .

[0047] According to some embodiments of the present invention, referring to Figure 4 and Figure 5The volute assembly includes a motor with an insulating structure, a volute component 400 and a bracket 410. The volute component 400 is located below the motor with an insulating structure. The multiple brackets 410 correspond to the multiple insulating fixing members 300 one by one. The lower end of the bracket 410 is fixedly connected to the volute component 400 by bolts. The upper end of the bracket 410 is provided with a threaded hole. The bolt member 340 is threadedly connected to the threaded hole at the upper end of the bracket 410.

[0048] Preferably, refer to Figure 4 and Figure 5 A driving component 120 is provided in the shell 100, and a rotating shaft 121 of the driving component 120 is downwardly penetrated into the chassis 200. The rotating shaft 121 is fixedly connected with a heat dissipation fan 130. The heat dissipation fan 130 is located between the chassis 200 and the volute component 400. When the rotating shaft 121 rotates, it can drive the heat dissipation fan 130 to rotate, thereby blowing air to dissipate heat from the chassis 200.
