By providing the motor bracket damper 155, vibration transmission between the power assembly 13 and the housing 11 can be isolated, and noise transmitted to the outside of the machine can be reduced. Preferably, the motor bracket shock pad 155 is of an L-shaped structure.

Further, the power assembly 13 is provided with a positioning portion, the positioning portion includes a main machine shock pad 156, the main machine shock pad 156 is disposed on the inner side of the motor support shock pad 155, and the cup assembly 20 and the main machine 10 clamp the main machine shock pad 156 when the cup assembly 20 is installed. Accordingly, vibration of the cup assembly 20 can be transferred to the main unit 10 after being doubly damped by the main unit damper pad 156 and the motor bracket damper pad 155, and vibration noise transferred from a gap between the cup assembly 20 and the main unit 10 can be reduced.

Further, in order to realize heat dissipation of the motor, the power assembly 13 is provided with a heat dissipation air channel communicated with the outside. As shown in fig. 9, the inner seat 16 is provided with an inner seat air inlet 166 and an inner seat air outlet 167 which are respectively communicated with the outside, and the support seat 12 is provided with a support seat air inlet 122 and a support seat air outlet 123. As shown in fig. 7 and 9 (arrows in the figures indicate the airflow direction), when the motor 14 is in operation, airflow flows along the following paths to achieve heat dissipation of the motor 14: the external air flow enters the inner cavity of the shell 11 from the support seat air inlet 122, then enters the inner cavity of the inner seat 16 through the inner seat air inlet 166, then enters the inner cavity of the motor cover 17 and the inner cavity 182 of the air duct cover, then enters the inner seat outer cavity 162 through the inner seat air outlet 167, and finally flows out through the support seat air outlet 123. The present application can further reduce noise by optimizing the cross-sectional area of each of the spaces described above. For example, the sectional areas of the spaces are different, and when the air flow passes through the spaces with different sectional areas, the air flow can be absorbed by the cavity walls to absorb noise with different wavelengths, so that the air noise can be reduced. The sectional area of the air flow channel can be sequentially small (the supporting seat air inlet 122), large (the cavity between the supporting seat 12 and the inner seat 16), small (the cavity between the inner seat air inlet 166), large (the cavity between the inner seat 16 and the motor cover 17), small (the gap between the motor cover 17 and the motor 14), large (the inner air channel cover cavity 182), small (the inner seat air outlet 167), large (the inner seat outer cavity 162), and small (the supporting seat air outlet 123), wherein the adjacent two cavities have abrupt cross section changes, noise sound waves are continuously expanded and compressed in space, noise energy can be continuously consumed, and noise is reduced. Meanwhile, the air flow turns for many times in the machine, so that the air flow noise caused by direct blowing of the air flow can be greatly reduced.

Further, in some embodiments, the support seat air inlet 122 and the inner seat air inlet 166 are offset. For example, the support seat air inlet 122 is disposed in the middle of the support seat 12, and the inner seat air inlet 166 is disposed at the bottom outer edge of the inner seat 16. In other embodiments, the support seat air outlet 123 and the inner seat air outlet 167 are offset. For example, the support seat air outlet 123 is disposed on a side wall of the support seat 12, and the inner seat air outlet 167 is disposed on a side wall of the inner seat 16 and higher than the support seat air outlet 123. In other embodiments, the support seat air inlet 122 and the inner seat air inlet 166 are offset, and the support seat air outlet 123 and the inner seat air outlet 167 are offset. Through the dislocation arrangement, the noise of air flow direct blowing can be avoided, the propagation path of the noise is prolonged, and the energy consumption of the noise is increased, so that the noise transmitted to the outside of the machine is reduced.

The support seat air inlet 122 and the inner seat air inlet 166 may have different cross-sectional shapes/cross-sectional areas, and the support seat air outlet 123 and the inner seat air outlet 167 may have different cross-sectional shapes/cross-sectional areas, which may be set according to actual requirements. For example, the air inlet 122 of the supporting seat is provided with a plurality of small hole air inlet holes, the diameters of the small holes are less than or equal to 4mm, and the center distance between the adjacent small holes is less than or equal to 5mm. Or, the supporting seat air outlet 123 is provided with a plurality of small hole air outlet 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. The inner seat air inlet 166 and/or the inner seat air outlet 167 are provided with a plurality of strip-shaped holes, for example.

Further, the support air inlet 122 is disposed in the middle of the support 12, and at least a part of the support air inlet 122 is opposite to the cooling fan 141 at the lower end of the motor 14. By facing at least part of the area of the air inlet 122 of the supporting seat to the cooling fan 141, the cooling fan 141 is assisted to suck air, the air circulation is quickened, and the cooling efficiency of the motor is improved.

Further, since the power assembly 13 only includes power related accessories, the whole structure is compact, the distance between the inner seat 16 and the center of gravity of the motor 14 is smaller than the distance between the housing 11 and the center of gravity of the motor 14, and the minimum distance between the inner seat 16 and the motor cover 17 is smaller than or equal to 40mm, and the maximum distance is smaller than or equal to 60mm, compared with the structure that the motor is directly mounted on the main body or the motor bracket is mounted on the main body in the past, the moment generated by vibration is smaller when the motor rotates at high speed, and the vibration is less likely to generate. The cup body assembly 20 is connected to the power assembly 13, the power assembly 13 is connected to the supporting seat 12, the whole stress is straight up and down, no cantilever exists, and the work is more stable. Meanwhile, the power component 13 excludes accessories such as a circuit board and a decoration part which are easy to vibrate (the accessories such as the circuit board and the decoration part can be arranged in the shell 11 and are independent of the power component 13), so that other structures which are easy to vibrate due to motor vibration can be prevented from vibrating.

It can be understood that the positioning part can also be a plurality of positioning columns arranged on the upper surface of the motor bracket and is matched with the cup body component in a positioning way through the positioning columns.

It will be appreciated that the location portion only extends from the housing at a location where it mates with the cup assembly, for example, only the boss or the location post extends from the housing and locates the assembly with the cup assembly, while other locations of the housing may be attached to the cup with only the appearance function, and do not perform the function defined.

The technical solution protected by the present utility model is not limited to the above embodiments, and it should be noted that, the combination of the technical solution of any one embodiment with the technical solution of the other embodiment or embodiments is within the scope of the present utility model. While the utility model has been described in detail in the foregoing general description and specific examples, it will be apparent to those skilled in the art that modifications and improvements can be made thereto. Accordingly, such modifications or improvements may be made without departing from the spirit of the utility model and are intended to be within the scope of the utility model as claimed.
