[0029] Please refer to Figure 3 , Figure 3 which is Figure 1 a cross-sectional view of the base 10 shown in

[0030] The base 10 includes a housing 11 and a motor assembly 30 housed within the housing 11. The housing 11 is provided on the outermost side of the base 10 and serves as the exterior part of the base 10. The housing 11 includes a detachable bottom case 110 and an upper cover 112, and the bottom case 110 and the upper cover 112 jointly enclose an accommodation space 114. The motor assembly 30 includes a motor cover 12 and a motor 13, both the motor cover 12 and the motor 13 are housed within the accommodation space 114, and the motor 13 is further disposed within the motor cover 12.

[0031] The motor 13 is encapsulated within the space enclosed by the motor cover 12 and the upper cover 112. Specifically, a first sealing ring 15 is clamped between the top end of the motor cover 12 and the upper cover 112 for sealing the gap between the motor cover 12 and the upper cover 112 to prevent gas from flowing in and out between the motor cover 12 and the upper cover 112.

[0032] The motor 13 includes a motor shaft 130, the upper cover 112 is provided with a shaft hole 1121, and the motor shaft 130 extends out from the shaft hole 1121 for driving connection with a cutter assembly in the cup assembly 20. A second sealing ring 16 is also clamped between the motor 13 and the upper cover 112 for sealing the gap between the motor 13 and the upper cover 112. Among them, the second sealing ring 16 is disposed around the rotating shaft 130 to prevent gas from flowing in and out at the motor shaft 130.

[0033] The upper cover 112 is further provided with a first sealing ring groove 1122 and a second sealing ring groove 1123. The first sealing ring 15 is installed within the first sealing ring groove 1122, and the second sealing ring 16 is installed within the second sealing ring groove 1123. At the middle part of the upper cover 112, there is a shaft hole 1121 for the motor shaft 130 to extend out. The second sealing ring groove 1123 surrounds the periphery of the shaft hole 1121, and the first sealing ring groove 1122 surrounds the periphery of the second sealing ring groove 1123.

[0034] Please refer to Figure 3 、 Figure 4 and Figure 5 , Figure 4 which is Figure 3 an enlarged view of part A in Figure 5 is an exploded view of the base 10.

[0035] The housing 11 is further provided with a positioning structure 111. In the orthographic projection along the axial direction of the shaft hole 1121, the positioning structure 111 is disposed around the periphery of the shaft hole 1121 and is coaxial with the shaft hole 1121.

[0036] The motor cover 12 is provided with a positioning and mating structure 120. In the orthographic projection along the axial direction of the motor shaft 130, the positioning and mating structure 120 is disposed around the periphery of the motor shaft 130 and is coaxial with the motor shaft 130. The positioning structure 111 and the positioning and mating structure 120 are in radial positioning and mating with respect to the motor shaft 130 and the shaft hole 1121.

[0037] As can be seen from the above description, the positioning structure 111 is coaxial with the shaft hole 1121, and the positioning and mating structure 120 is coaxial with the motor shaft 130. Through the radial positioning and mating of the positioning structure 111 and the positioning and mating structure 120, the coaxiality of the motor shaft 130 and the shaft hole 1121 is ensured, the installation error of the motor assembly 30 in the housing 11 is reduced, and further the vibration of the machine base 10 caused by the offset of the motor assembly 30 is alleviated.

[0038] In this embodiment, the upper cover 112 is located above the bottom shell 110. The upper cover 112 is provided with the shaft hole 1121, and the bottom shell 110 is provided with the positioning structure 111. With such a setting, the positioning and mating structure 120 can be correspondingly provided at the bottom of the motor cover 12 to cooperate with the positioning structure 111. In this way, when installing the motor assembly 30, the relative position of the motor assembly 30 and the bottom shell 110 can be adjusted by first mating and positioning the positioning and mating structure 120 and the positioning structure 111, and then the upper cover 112 is installed. Such an assembly process and assembly procedure are more reasonable. Of course, in some other embodiments, the shaft hole 1121 and the positioning structure 111 can both be provided on the upper cover 112. Correspondingly, the positioning and mating structure 120 can be provided on the top of the motor cover 12.

[0039] In one embodiment, one of the positioning structure 111 and the positioning and mating structure 120 is set as a positioning protrusion, and the other is set as a positioning groove.

Of course, it can also be set that the bottom shell 110 is provided with the positioning protrusion and the motor cover 12 is provided with the positioning groove.

[0040] In one embodiment, as Figure 4 shown, a pit 1200 is provided in the middle area of the positioning protrusion. The pit 1200 can reduce the material usage, making the wall thickness at the positioning protrusion relatively uniform. In addition, in an embodiment where the motor cover 12 is provided with the positioning protrusion and is an injection molded part, the pit 1200 can reduce the deformation of the positioning protrusion during the cooling process after molding.

[0041] In one embodiment, the positioning groove includes a positioning surface 1111 for cooperating with the positioning protrusion, and the positioning surface 1111 is set as a flexible surface. That is, during positioning and matching, the positioning protrusion can contact the flexible surface of the positioning groove, thereby alleviating and absorbing the vibration generated by the motor 13 and reducing noise.

[0042] The specific method of setting the positioning surface as a flexible surface is not limited. In this embodiment, the shell 11 includes a shell body 11a and a shock-absorbing member 11b made of a flexible material, the shell body 11a is provided with a mounting groove 1112, the shock-absorbing member 11b is arranged in the mounting groove 1112, and the shock-absorbing member 11b is formed with the positioning groove and the positioning surface 1111. In this way, the surface of the shock-absorbing member 11b is used to form a flexible surface, which not only achieves positioning but also alleviates vibration. The shock-absorbing member 11b can be integrally formed in the mounting groove 1112, or it can be assembled in the mounting groove 1112 after being processed separately. In this embodiment, the latter is adopted.

[0043] In one embodiment, the shock absorbing member 11b can be processed separately, and the shock absorbing member 11b is detachably disposed in the mounting groove 1112. This facilitates the replacement of the shock absorbing member 11b.

[0044] In one embodiment, the mounting groove 1112 is configured as a T-shaped groove, and the shock absorber 11b is configured as a hollow T-shaped member. The shock absorber 11b and the mounting groove 1112 are installed in a structurally corresponding manner, that is, the large ends of the shock absorber 11b and the mounting groove 1112 are installed in a corresponding manner, and the small ends of the shock absorber 11b and the mounting groove 1112 are installed in a corresponding manner, and the hollow part of the shock absorber 11b forms the positioning groove. In this way, the shock absorber 11b can be supported on the step surface of the mounting groove 1112, ensuring the stability and reliability of the installation position of the shock absorber 11b.

[0045] In one embodiment, the interference amount when the positioning protrusion is inserted into the positioning groove can be set to 0.2-0.7 mm, for example, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, thereby ensuring the compactness of the motor assembly 30 and the bottom shell 110 and reducing the shaking amount.

[0046] In one embodiment, the shock absorber 11b further includes a contact surface 1113 for contacting the peripheral part of the positioning protrusion, and the contact surface 1113 is provided with a convex bump 1114, and the convex bump 1114 protrudes from the surface where the mounting groove is located.

Specifically, the contact surface is at the peripheral portion of the positioning protrusion.

[0047] Please refer to Figure 6 , Figure 6 which is another exploded view of the machine base 10, in which the upper cover 112 is removed.

[0048] The machine base 10 further includes a PCB bracket 14 and a PCB board (not shown) mounted on the PCB bracket 14. The PCB bracket 14 and the PCB board are disposed in the accommodation space 114, and the PCB bracket 14 is arranged side by side with the motor assembly 30.
