In this embodiment, the motor cover 16 and the air duct cover 18 may collectively form a third chamber 120 that provides sound insulation while providing a heat dissipation air duct. The shock absorbing member 190 is, for example, a shock absorbing pad, a shock absorbing ring, a shock absorbing cotton, or the like, and absorbs a part of noise when the shock absorbing cotton is used.

Further, as shown in fig. 8, an extension portion 174 extending outward is disposed on one side of the inner seat 17, the extension portion 174 and the base 12 enclose to form an inner seat outer cavity 175, the inner seat outer cavity 175 is communicated with the air duct cover inner cavity 181, and a ratio of a cross-sectional area of the inner seat outer cavity 175 to a cross-sectional area of the air duct cover inner cavity 181 is greater than 1.5.

Specifically, when the motor is discharging air, the airflow enters the inner base outer cavity 175 after passing through the air duct cover inner cavity 181, and the inner base outer cavity 175 provides an enlarged cavity, which increases the consumption of noise energy at the air outlet, thereby facilitating the reduction of the noise at the air outlet. Further, a sealing cotton 176 is disposed between the extension 174 and the base 12 to further prevent noise from being emitted.

As a preferred embodiment of the present application, the inner seat 17 is provided with an inner seat air inlet 177 and an inner seat air outlet 178 respectively communicated with the outside, the third chamber 120 is communicated with the second chamber 110, and the inner seat air inlet 177, the second chamber 110, the third chamber 120 and the inner seat air outlet 178 form the heat dissipation air duct.

As shown in fig. 9 and 10, the airflow flowing process of the power assembly 13 provided with the heat dissipation air duct is as follows: the airflow enters the second chamber 110 from the inner seat inlet 177, then enters the third chamber 120 from the gap between the motor cover 16 and the motor 14, and after the cold air carries away the heat of the motor 14, the airflow enters the second chamber 110 from the third chamber 120 and finally flows out from the inner seat outlet 178.

Further, the base 12 is provided with a base air inlet 122 and a base air outlet 123, so that the heat dissipation air duct of the power assembly 13 can communicate with the outside. In some embodiments, the base intake vent 122 and the inner base intake vent 177 are offset. For example, the base inlet vent 122 is disposed in the middle of the base 12 and the inner seat vent 177 is disposed at the bottom outer edge of the inner seat 17. In other embodiments, the base outlet 123 and the inner seat outlet 178 are offset. For example, the base outlet 123 is disposed on a sidewall of the base 12, and the inner seat outlet 178 is disposed on a sidewall of the inner seat 17 and is higher than the base outlet 123. In other embodiments, the base intake vent 122 and the inner seat intake vent 177 are disposed in a staggered manner, and the base outlet vent 123 and the inner seat outlet vent 178 are disposed in a staggered manner. Through the dislocation arrangement, the noise of air flow direct blowing can be avoided, meanwhile, the propagation path of the noise is prolonged, the energy consumption of the noise is increased, and therefore the noise transmitted to the outside of the machine is reduced.

The base air inlet 122 and the inner seat air inlet 177 may have different sectional shapes/sectional areas, and the base air outlet 123 and the inner seat air outlet 178 may have different sectional shapes/sectional areas, which may be set according to actual requirements. For example, the base air inlet 122 is provided with a plurality of small air inlet holes, the diameter of each small hole is less than or equal to 4mm, and the center distance between adjacent small holes is less than or equal to 5mm. Or the base air outlet 123 is provided with a plurality of small hole air outlets, the diameter of each small hole is less than or equal to 4mm, and the center distance between every two adjacent small holes is less than or equal to 5mm. The inner seat intake vent 177 and/or the inner seat outlet vent 178 are provided with a plurality of strip-shaped holes, for example.

Further, the base air inlet 122 is disposed in the middle of the base 12, and at least a partial area of the base air inlet 122 faces the heat dissipation fan 159 at the lower end of the motor 14. At least partial area of the base air inlet 122 is opposite to the heat radiation fan 159, so that air suction of the heat radiation fan 159 is facilitated, air circulation is accelerated, and heat radiation efficiency of the motor is improved.

As shown in fig. 10 (the arrows indicate the airflow direction), when the motor 14 is in operation, the airflow flows along the following path to dissipate heat of the motor 14: the external air flow enters the inner cavity of the chassis 11 through the base air inlet 122, then enters the inner cavity of the inner base 17 through the inner base air inlet 177, then enters the inner cavity of the motor cover 16 and the duct cover inner cavity 181, then enters the inner base outer cavity 175 through the inner base air outlet 178, and finally flows out through the base air outlet 123. This application can further reduce the noise through optimizing the sectional area in each above-mentioned space. For example, the cross sections of the spaces are different, and when the airflow passes through the spaces with different cross sections, the noise with different wavelengths can be absorbed by the cavity wall, which is beneficial to reducing the wind noise. The sectional area of the airflow channel can be sequentially small (a base air inlet 122), large (a cavity between the base 12 and the inner base 17), small (an inner base air inlet 177), large (a cavity between the inner base 17 and the motor cover 16), small (a gap between the motor cover 16 and the motor 14), large (an air duct cover inner cavity 181), small (an inner base air outlet 178), large (an inner base outer cavity 175), small (a base air outlet 123), wherein the adjacent two cavities have abrupt cross section changes, noise sound waves are continuously and alternately expanded and compressed in space, noise energy can be continuously consumed, and noise is reduced. Meanwhile, the airflow turns for many times in the machine, so that the airflow noise caused by the direct blowing of the airflow can be greatly reduced.

Further, because the power assembly 13 only comprises power-related accessories, the whole machine is compact in structure, the distance from the inner seat 17 to the center of gravity of the motor 14 is less than the distance from the casing 11 to the center of gravity of the motor 14, the minimum distance between the inner seat 17 and the motor cover 16 is less than or equal to 40mm, and the maximum distance is less than or equal to 60 mm. The cup body assembly 20 is connected to the power assembly 13, the power assembly 13 is connected to the base 12, the whole stress is straight up and down, no cantilever exists, and the work is more stable. Meanwhile, the power assembly 13 excludes the accessories such as circuit boards and ornaments which are easy to vibrate (the accessories such as the circuit boards and the ornaments can be arranged in the first chamber 100 and are independent of the power assembly 13), so that the vibration of the motor, which causes other structures which are easy to vibrate, can be prevented from vibrating along with the vibration.

It can be understood that the positioning portion can also be a plurality of positioning columns arranged on the upper surface of the motor support, and is in positioning fit with the cup body assembly through the positioning columns.

It can be understood that, only the part of the positioning part which is matched with the cup body assembly extends out of the machine shell, for example, only the bulge part or the positioning column extends out of the machine shell and is connected with the cup body assembly positioning assembly, and other parts of the machine shell can be connected with the cup body only in an appearance function fitting mode and do not have a limiting function.
