As a preferred embodiment of this embodiment, the air guiding groove 43 extends from the side of the second air guiding cavity 42 along the horizontal direction, so that the air guiding groove 43 is relatively easy to manufacture and mold.

Preferably, the wind scooper 4 includes a wind guiding barrel 44 enclosing the first wind guiding cavity 41, a wind guiding seat 45 enclosing the second wind guiding cavity 42, and a wind guiding frame 46 enclosing the wind guiding groove 43. The air duct 44 extends downward from the bottom of the air guide seat 45, and the air guide frame 46 extends laterally from the side of the air guide seat 45.

The wall thickness of the air duct 44 specifically guides the distance between the inner wall of the air duct 44 close to the first air guiding cavity 41 and the outer wall of the air duct 44 far from the first air guiding cavity 41. If the wall thickness of the air duct 44 is designed to be too thin, the air duct 44 is easily deformed and damaged in the using process; if the wall thickness of the air guide duct 44 is too large, the air guide duct 44 will be large, heavy and costly.

The distance between the air duct 44 and the motor 2 specifically refers to a horizontal distance between an inner side wall of the first air guiding cavity 41 and an outer side wall of the motor 2 close to the inner side wall of the first air guiding cavity 41. If the distance between the air duct 44 and the motor 2 is designed to be too small, the wind is not beneficial to pass through the motor 2, so that the heat dissipation effect is influenced, and the assembly of the motor 2 and the air duct 44 is easily influenced; if the distance between the air duct 44 and the motor 2 is too large, the air duct 44 will be large, heavy and costly. Here, the distance between the air duct 44 and the motor 2 is set to be 2mm-30mm, which is beneficial to ensuring the heat dissipation effect of the motor 2, and can control the size, weight and material cost of the air duct 44 within a reasonable range, and the comprehensive performance is better.

If the wall thickness of the air guide seat 45 is designed to be too thin, the air guide seat 45 is easily deformed and damaged in the using process; if the wall thickness of the wind guide seat 45 is too large, the wind guide seat 45 will have a large size, a large weight, and a high material cost. Here, the wall thickness of the air guide seat 45 is set to 0.5mm-5mm, which is beneficial to ensuring the strength of the air guide seat 45, and can control the size, weight and material cost of the air guide seat 45 within a reasonable range, and the comprehensive performance is better.

If the distance between the air guide seat 45 and the first cooling fan 3 is designed to be too small, the interference between the air guide seat 45 and the first cooling fan 3 is easily caused; if the distance between the air guiding seat 45 and the first heat dissipating fan 3 is too large, the air guiding seat 45 will have a larger size, a larger weight, and a higher material cost. Here, the distance between the air guiding seat 45 and the first heat dissipating fan 3 is set to be 2mm-50mm, which is beneficial to preventing the interference between the air guiding seat 45 and the first heat dissipating fan 3, and can control the size, weight and material cost of the air guiding seat 45 within a reasonable range, and the comprehensiveness is better.

Preferably, the wall thickness of the air guide frame 46 is 0.5mm-5 mm. The wall thickness of the air-guiding frame 46 specifically guides the distance between the inner wall of the air-guiding frame 46 close to the first air-guiding cavity 41 and the outer wall of the air-guiding frame 46 far from the first air-guiding cavity 41. If the wall thickness of the air guide frame 46 is designed to be too thin, the air guide frame 46 is easily deformed and damaged in the using process; if the wall thickness of the air guide frame 46 is too large, the air guide frame 46 will be large in size, heavy in weight, and high in material cost. Here, the wall thickness of the air guide frame 46 is set to 0.5mm-5mm, which is beneficial to ensuring the strength of the air guide frame 46, and can control the size, weight and material cost of the air guide frame 46 within a reasonable range, and the comprehensive performance is better.

Further, the embodiment further provides the base assembly 100, which includes a base housing 1 and a motor 2 disposed in the base housing 1, wherein a first ventilation opening 121 is disposed at the bottom of the base housing 1, a second ventilation opening 111 is disposed at the side of the base housing 1, the motor 2 has an upper output shaft 21 and a lower output shaft 22 which are disposed along the vertical direction in a reverse direction, the base assembly 100 further includes a first cooling fan 3 and the wind scooper 4, the first cooling fan 3 and the wind scooper 4 are assembled and connected to the upper output shaft 21, the first opening 411 is disposed opposite to the first ventilation opening 121, and the second opening 431 is disposed opposite to the second ventilation opening 111.

Specifically, the motor 2 is installed in the housing case 1 in such a manner that the center axis thereof is vertically placed, and the upper output shaft 21 is located above the lower output shaft 22. In the base assembly 100 provided by this embodiment, because the first cooling fan 3 is directly mounted on the upper output shaft 21 of the motor 2, on one hand, the independent arrangement of the power of the first cooling fan 3 is omitted, the number of components of the base assembly 100 is reduced, and the structure of the base assembly 100 is effectively simplified; on the other hand, the rotating speed of the first cooling fan 3 can be changed along with the change of the output rotating speed of the motor 2, so that when the motor 2 rotates at a high speed to generate a large amount of heat, the first cooling fan 3 also rotates at a high speed along with the motor 2 to accelerate the air flowing speed, so that more heat on the motor 2 can be taken away by the air flowing at a high speed, the heat dissipation effect inside the base assembly 100 is effectively guaranteed, and the satisfaction degree of a user on a product is favorably improved. In addition, the base assembly 100 provided in this embodiment adopts the wind scooper 4, so that the flow of air between the first air vent 121 and the second air vent 111 can be better guided, so that the cold air entering the base housing 1 from the outside can better flow through the motor 2 and the first cooling fan 3, which is beneficial to improving the cooling effect of the motor 2 and preventing the problems of air flow disorder and large air flow noise in the base assembly 100.

Preferably, the first heat dissipation fan 3 is a centrifugal fan, the first ventilation opening 121 is an air inlet, and the second ventilation opening 111 is an air outlet. The centrifugal fan can suck air from the axial direction of the fan and then throw the air out from the circumferential direction by utilizing centrifugal force. Specifically, when the first cooling fan 3 operates, the second air guiding cavity 42 forms a low pressure area, and the first air guiding cavity 41 forms a high pressure area, so that air in the first air guiding cavity 41 is sucked upwards, thus, external cold air is sucked into the base housing 1 from the first vent 121 at the bottom of the base housing 1, the external cold air flows from bottom to top after entering the base housing 1 and flows to the first cooling fan 3 after exchanging heat through the motor 2, the first cooling fan 3 throws hot air flowing to the first cooling fan through the motor 2 to the second vent 111 at the side of the base housing 1, and finally, the hot air after exchanging heat can be discharged from the second vent 111.
