A control board chamber is formed between the main shaft connecting seat and the cover body. A control board is arranged in the control board chamber.
[0006] A main shaft seal plug is arranged at the position of the main shaft connecting seat corresponding to the main shaft. The control board is arranged in the control board chamber on one side of the main shaft connecting seat through electronic silica gel.
[0007] Preferably, a main shaft sleeve connected to the main shaft is arranged on the main shaft connecting seat. The main shaft seal plug is clamped in one end of the main shaft sleeve located in the control board chamber.
[0008] Preferably, the main shaft seal plug abuts between the main shaft sleeve and the cover body.
[0009] Preferably, the cover body is clamped on the main shaft connecting seat.
[0010] Preferably, a plurality of annularly distributed clamping grooves are formed on the inner side wall of the main shaft connecting seat. A plurality of annularly distributed buckle ends are arranged on the cover body. The clamping grooves and the buckle ends are aligned and distributed, and the clamping grooves and the buckle ends are adapted to be clamped.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. The utility model is provided with a motor coil chamber, a control board chamber and a main shaft sealing plug. Through the main shaft connecting seat, two chamber structures are formed.
