One end of the connecting rod 23 is connected to the mounting portion 22, and the other end is connected to the front cover 10.

Referring to fig. 2 to 5, the mounting portion 22 is a circular plate-shaped structure, and a through hole 21 is formed at the center thereof. The motor 30 is installed at one side of the installation part 22 away from the outlet port 11, and the output shaft 31 of the motor 30 passes through the through hole 21 such that the output shaft 31 passes through the installation part 22 to protrude into the other side of the installation part 22. The fan 40 is disposed at one side of the mounting portion 22 near the outlet 11, and since the output shaft 31 of the motor 30 passes through the through hole 21, the output shaft 31 can be coupled with the fan 40.

Preferably, a bearing is provided between the output shaft 31 of the motor 30 and the through hole 21 to facilitate rotation and support of the output shaft 31.

Further, four connecting rods 23 are uniformly distributed along the circumferential direction of the mounting portion 22. That is, the four connecting rods 23 are in a cross shape as a whole. The connection rod 23 has one end connected to the outer edge of the mounting portion 22 and the other end connected to the front cover 10, so that the mounting bracket 20 is integrally fixed to the front cover 10.

The connection between the connecting rod 23 and the mounting portion 22 includes a mode in which the connecting rod 23 and the mounting portion 22 are integrally formed, and also includes a mode in which the connecting rod is formed separately and then fixed at a later stage.

In the solution of the present embodiment, the fan 40 and the motor 30 are respectively installed on two sides of the mounting bracket 20, so that the motor 30 and the fan 40 can be assembled with the mounting bracket 20, and compared with the case of only fixing the motor 30, the stability of installing the fan 40 and the motor 30 on the mounting bracket 20 can be improved, and the stability of the fan 40 in the rotation process can be improved.

Moreover, by arranging the mounting part 22 and the connecting rod 23, on the basis that the mounting part 22 provides sufficient mounting space for the motor 30 and the fan 40, the connecting rod 23 connects the mounting part 22 with the front housing 10, the structure is simple, and the reduction of the production cost of the mounting bracket 20 is facilitated. Meanwhile, the connecting rods 23 uniformly distributed along the circumferential direction of the mounting portion 22 can ensure the mounting stability of the mounting bracket 20.

In the solution of the present embodiment, by providing the mounting groove 24 on the mounting bracket 20 and providing the protrusion 41 on the fan 40, the protrusion 41 is inserted into the mounting groove 24 when the fan 40 is assembled with the mounting bracket 20 in place. Therefore, the mounting groove 24 can limit the protruding portion 41 in the circumferential direction, that is, limit the fan 40, so as to prevent the fan 40 from moving greatly in the circumferential direction, which is beneficial to improving the stability of the fan 40 in the working process.

Moreover, the assembling relationship between the protruding portion 41 and the mounting groove 24 is beneficial to preventing dust from entering the joint of the output shaft 31 and the fan 40, thereby helping to maintain a good connecting effect between the fan 40 and the output shaft 31 for a long time and ensuring the normal operation of the fan 40.

As shown in fig. 3 and 6, in one embodiment, the motor 30 has four fixing legs 32 on a side thereof close to the mounting bracket 20, the fixing legs 32 have a supporting portion 321 extending in a circumferential direction of the motor 30, and the supporting portion 321 is embedded in the mounting bracket 20.

Specifically, four fixing legs 32 are uniformly distributed along the circumferential direction of the motor 30, and one end of the fixing leg 32 away from the motor 30 is bent toward the circumferential direction of the motor 30, thereby forming the supporting portion 321. The mounting bracket 20 is provided with a small groove into which the support portion 321 is inserted. When the motor 30 and the mounting bracket 20 are mounted in place, the support portion 321 is inserted into the small groove of the mounting bracket 20.
