Description

Technical Field

[0001] The utility model belongs to the technical field of food processing equipment, and in particular relates to a host machine for a food processing machine. Background Art

[0002] Existing food processing machines, such as meat grinders, generally include a main machine with a motor installed therein, a crushing cup assembly arranged below the main machine, and the crushing cup assembly includes a crushing cup, a cup cover arranged at the mouth of the crushing cup, and a crushing knife detachably mounted on the crushing cup. The top of the crushing knife passes through the through hole of the cup cover and is in transmission cooperation with the output end of the motor, and the bottom of the crushing knife is provided with a positioning groove that is plugged and cooperated with a positioning shaft protruding from the inner bottom surface of the crushing cup.

[0003] The main machine for a meat grinder usually includes a housing, a movable part, a switch, a button, a switch connecting rod movably arranged relative to the housing, a motor arranged in the housing, and a mounting cover. In one of the prior arts, the housing is assembled to the housing, the movable part is a cantilever structure arranged on the mounting cover, the cantilever includes a fixed end and a movable end, a switch is also installed on the cantilever structure, and the switch is also arranged corresponding to the button. The meat grinder also includes a bowl cover. After the main machine is placed on the bowl cover, the abutting part of the bowl cover abuts against the switch connecting rod so that the switch connecting rod is subjected to force. When the switch connecting rod is subjected to force to push the cantilever structure, the cantilever structure drives the switch to move from the initial position to the button until the switch reaches the trigger position. In this case, the button is pressed, and the button triggers the switch to close so that the motor is connected to the power supply.

[0004] However, the above technical solution requires a cantilever structure to be set on the mounting cover, and the cantilever structure also needs to be set to avoid the top of the motor, which undoubtedly requires a hollow setting in the middle of the mounting cover, reducing the strength of the cantilever structure and making the structure of the mounting cover more complicated. In addition, the cantilever structure and the mounting cover are an integrated structure. When the cantilever structure is subjected to long-term and multiple heavy pressing of the buttons by the user, the fixed end of the cantilever structure is prone to breakage and failure.

[0021] Due to the adoption of the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0022] 1. The utility model provides a main unit for a food processing machine. By providing an avoidance hole for the top of the switch connecting rod to extend into on the bracket of the decorative part, there is no need to provide an additional cantilever structure, the structural change of the bracket is smaller, and the structure is simpler. The switch is provided on the top of the switch connecting rod, so that the switch and the switch connecting rod form a whole and are axially movable relative to the avoidance hole. By arranging the switch above the bracket and correspondingly arranged with the button, the trigger alignment is accurate when the user presses the button. In other words, compared with the prior art, this solution realizes the opening and closing of the switch by directly driving the switch along the axial direction of the shell through the connecting rod, and at the same time eliminates the cantilever structure, saves material costs, and effectively improves the service life of the main unit. There is no need to consider the impact of the strength of the cantilever structure on the life and the avoidance of the motor, and the structure of the bracket is simplified.

[0023] 2. As a preferred embodiment of the present application, the present application installs the switch by means of the first mounting bracket, thereby achieving good fixation of the switch. On this basis, the first mounting bracket is also arranged toward the center of the bracket, so that the motor and the switch are almost in a vertically facing position relationship, and the distance between the switch and the motor through the avoidance hole is shorter, which reduces the cost of the wiring harness and effectively avoids the problem of tangling when the connection is too long and the need for rolling and bundling.

[0024] 3. As a preferred embodiment of the present application, the present application forms a base of the first mounting frame by providing an upwardly extending reinforcing plate at the top of the rod body, and on this basis, an extension buckle is provided on one side of the reinforcing plate. The provision of the reinforcing plate improves the fixing reliability of the extension buckle. There are multiple extension buckles that are relatively arranged to buckle the switch, thereby achieving a simple installation of the switch without making structural changes to the bracket, and the direct structure is also simpler.

[0025] 4. As a preferred embodiment of the present application, the present application is beneficial to improve the overall balance of the switch connecting rod by arranging the first mounting frame and the second mounting frame on both sides of the reinforcing plate. At the same time, the first mounting frame and the second mounting frame are respectively installed with the switch and the elastic member, that is, the switch and the elastic member are arranged horizontally. Compared with the existing solution in which the elastic member is arranged above the switch, it is beneficial to reduce the overall height of the host and optimize the small space design of the host. More importantly, the elastic member in this solution has a multi-purpose effect. On the one hand, it can be used to reset the button, and at the same time, it can also reset the switch connecting rod. Compared with the prior art, a spring needs to be set at the switch connecting rod, and an additional spring is set at the button to reset the button. The structure is simpler and the cost is lower.

[0026] 5. As a preferred embodiment of the present application, the present application provides a flat platform for the setting of the limiting ribs by setting a laterally extending support plate. In this way, the spring is clamped on the limiting ribs, which is easy to install and has a longer service life than the cantilever structure used in the prior art.

[0027] 6. As a preferred embodiment of the present application, in order to better ensure that the switch connecting rod will not be offset when moving axially along the avoidance hole, an axially extending guide groove is provided on the inner peripheral wall of the avoidance hole, and a guide rib adapted to the guide groove is convexly provided on the outer periphery of the mounting bracket, so that the switch connecting rod can only move axially along the guide groove. In addition, the cooperation between the guide groove and the guide rib also limits the circumferential rotation of the switch connecting rod to a certain extent, and the switch triggering is more reliable.

[0028] 7. As a preferred embodiment of the present application, the present application provides a circumferentially extending limit groove on the side wall of the shell, and the switch connecting rod is accommodated in the limit groove, which also plays a good guiding role for the circumferential movement of the switch connecting rod, thereby preventing the swing of the switch connecting rod from affecting the triggering. Of course, whether the bottom end of the switch connecting rod can accurately extend from or extend into the bottom of the shell has a great impact on the user's experience. To this end, the present application also provides a guide column protruding from the inner bottom wall of the shell, and the guide column is provided with a through hole for the bottom of the switch connecting rod to extend, so that the lower end of the switch connecting rod is limited in the through hole of the guide column, and when the user installs the host, there will be no problem of the switch connecting rod being lifted up and stuck; of course, when the user picks up the host, it can also avoid the situation where the switch connecting rod cannot extend out of the bottom wall of the shell.

[0029] 8. As a preferred embodiment of the present application, the present application first provides a buckle extending downward on the bottom surface of the bracket, and provides a metal frame on the top of the motor, and clamps the buckle on the metal frame, so that the motor is first fixed to the bracket, that is, the motor and the decorative part first form an integral part. Then, the integral part is fixedly connected to the housing through the decorative part, so that the motor is clamped and fixed between the bracket and the bottom wall of the housing. Compared with the prior art, this solution also achieves the same effect of fixing with the housing without screws and easy installation, and also improves the installation method. It only needs to position and install the integral part formed by the motor and the decorative part with the housing, and the button is directly installed on the top of the decorative part, eliminating the need for an upper cover, which is lower in cost.

[0030] 9. As a preferred embodiment of the present application, the present application provides a receiving cavity for inserting the tail end of the output shaft of the power supply motor at the top of the bracket, and the receiving cavity bulges upward, which is beneficial to limiting the tail end of the motor on the one hand, and is beneficial to reducing the overall height of the host on the other hand, that is, the raised part will partially overlap with the switch. Alternatively, in another scheme, a shock absorber is clamped between the bottom surface of the bracket and the top surface of the metal frame, and the shock absorber is used to separate the motor from the components above the top surface of the bracket to prevent carbon powder from splashing onto the components. The shock absorber separates the bracket and the motor to avoid hard contact. During operation, the vibration noise generated by the motor is effectively alleviated by the shock absorber, thereby improving the noise. Alternatively, in another scheme, the limiting column on the bracket is inserted into the limiting hole of the metal frame to limit the motor laterally and reduce the lateral deflection of the motor.

[0031] 10. As a preferred embodiment of the present application, in order to prevent the switch connecting rod from extending infinitely from the bottom of the shell when it naturally falls back without being subjected to an upward push-out force, the present application also axially limits the switch connecting rod through the step surface formed by the top surface of the reduction gear housing. In this way, the reduction gear housing not only protects the internal reduction gear, but also plays an axial limiting role for the switch connecting rod. There is no need to set an additional structure for limiting the rod body inside the shell, which simplifies the internal structure of the shell. At the same time, in order to prevent the switch connecting rod from slipping out of the avoidance hole and failing to slide smoothly into the avoidance hole when the switch connecting rod is lifted up again, resulting in a trigger failure, it is also set that in the limited state, the switch connecting rod is located within the axial height range of the avoidance hole.

[0050] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0051] It should be noted that many specific details are elaborated in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific implementation methods disclosed below.

[0052] like Figures 1 to 11 As shown, the present application provides a host 1 for a food processing machine, and the food processing machine applied by the host 1 includes, in addition to the host 1, a cup cover 2 arranged below the host 1, a crushing cup 6 covered by the cup cover 2, and a crushing knife 3 arranged in the crushing cup 6. Among them, a motor 13 is arranged in the host 1, and the top of the crushing knife 3 is transmission-connected to the output end of the motor 13 through a through hole on the cup cover 2, and the bottom end of the crushing knife 3 is limited to the inner bottom surface of the crushing cup 6.

[0053] Specifically, refer to Figure 1 , 2 The host 1 of the present application also includes a housing 11, a switch 41 electrically connected to the motor 13, a switch connecting rod 42, a decorative piece 5 and a button 12. The decorative piece 5 is assembled on the top of the housing 11, the button 12 is installed above the decorative piece 5, and the switch connecting rod 42 is movably arranged along the axial direction of the housing 11. The switch 41 is installed on the top of the switch connecting rod 42, and the decorative piece 5 includes a decorative ring 52 assembled with the housing 11, and a bracket 51 arranged inside the decorative ring 52, and the bracket 51 is provided with an avoidance hole 53 for the top of the switch connecting rod 42 to extend into. By providing the avoidance hole 53 for the top of the switch connecting rod 42 to extend into the bracket 51 of the decorative piece 5, there is no need to provide an additional cantilever structure, the structural change of the bracket 51 is smaller, and the structure is simpler. The switch connecting rod 42 supports the switch 41 so that the switch 41 is located above the bracket 51, and the switch 41 and the switch connecting rod 42 form a whole and are axially movable relative to the avoidance hole 53. In this solution, the switch 41 is disposed above the bracket 51 and is disposed corresponding to the button 12, so that when the user presses the button 12, the trigger alignment is accurate.

[0054] When the host 1 is separated from the cup cover 2, the bottom end of the switch connecting rod 42 extends out of the bottom wall of the housing 11, so that the switch 41 does not reach the trigger position. Even if the user presses the button 12, it will trigger and touch the contact on the switch 41, solving the safety problem of false triggering and starting when the host 1 is separated from the cup cover 2. When the host 1 is assembled on the cup cover 2, the cup cover 2 has an upward push force on the switch connecting rod 42. At this time, the switch connecting rod 42 drives the switch 41 to move up to the trigger position, and when the button 12 is pressed down by the user and pressed down to the trigger position, the button 12 touches the contact of the switch 41, so that the switch 41 is closed and the motor 13 is in a working state, which can drive the crushing knife 3 in the crushing cup 6 to rotate. Compared with the prior art, this solution realizes the movement of the switch 41 along the axial direction of the housing 11 directly by the connecting rod to realize the opening and closing of the switch 41, and at the same time, the cantilever structure is omitted, the cost is lower, and the service life of the host 1 is effectively improved. There is no need to consider the strength of the cantilever structure affecting the life and the avoidance of the motor 13, and the structure of the bracket 51 is simplified.

[0055] It should be noted that the switch connecting rod 42 is movably arranged along the axial direction of the housing 11, which means that the switch connecting rod 42 can move toward the key 12, or move downward away from the key 12. The switch 41 is located above the bracket 51, which means that the top surface of the switch 41 is higher than the top surface of the bracket 51, and does not mean that it is higher than the ribs, the accommodating cavity 512 and other components arranged on the top surface.

[0056] Furthermore, in order to prevent the switch link 42 from extending infinitely from the bottom of the housing 11 when it naturally falls back without being subjected to an upward push-out force. In this embodiment, the switch link 42 includes a rod body 423, and the rod body 423 includes a first rod body 423 with a larger diameter, and a second rod body 423 with a smaller diameter disposed below the first rod body 423. A step 4231 is formed at the connection between the first rod body 423 and the second rod body 423. In this solution, the step 4231 formed on the top surface of the housing of the reduction box 133 is axially limited (see for details) Figure 2 , 6 , 7), so that the housing of the reduction box 133 not only protects the internal reduction gear, but also plays an axial limiting role for the switch connecting rod 42. There is no need to set an additional structure for limiting the rod body 423 inside the shell 11, which simplifies the internal structure of the shell 11.

[0057] In addition, by setting the limit state, the switch connecting rod 42 is located within the axial height range of the avoidance hole 53, which effectively ensures that the switch connecting rod 42 will not extend infinitely from the bottom of the housing 11 when it falls back, and in particular, ensures that the switch connecting rod 42 is always located within the axial range of the avoidance hole 53. In this way, it is avoided that after the switch 41 slides down from the avoidance hole 53, when it is subjected to an upward push force again, the switch connecting rod 42 cannot extend into the avoidance hole 53, resulting in a trigger failure problem.

[0058] Further, the specific structure of the switch 41 component 4 is described, and the present application provides the following two embodiments:

[0059] Embodiment 1:

[0060] See also Figure 5 , 6 As shown, the switch connecting rod 42 includes a rod body 423, a first mounting frame provided at the top of the rod body 423 and used to mount the switch 41, a reinforcing plate 424 extending in the direction is also provided at the top of the rod body 423, and the first mounting frame is an extension buckle 425 provided at one side of the reinforcing plate 424, and the extension buckle 425 is provided with two opposite buckles for buckling the switch 41 to one side of the reinforcing plate 424. Preferably, the extension buckle 425 and the reinforcing plate 424 are integrally formed. A fixing column is also provided on the side of the reinforcing plate 424, and a fixing hole matching the fixing column is provided on the switch 41, and the fixing hole of the switch 41 is laterally inserted into the fixing column so that the fixing column axially supports the switch 41, and then the buckle 511 laterally buckles the switch 41, thereby improving the reliability of the switch 41 being fixed on the switch connecting rod 42.

[0061] It is understandable that the number of extension buckles 425 can also be four, and they are arranged opposite to each other to buckle the switch 41. The structure of the first mounting frame can also be a mounting box provided on one side of the reinforcing plate 424, the top surface of the mounting box is open, and the switch 41 only needs to be installed in the mounting box from top to bottom.

[0062] Embodiment 2:

[0063] In this embodiment, the installation structure of the first mounting bracket and the switch 41 is consistent with that of the first embodiment. Figure 6 , 7 In addition to the rod body 423, the first mounting frame for mounting the switch 41, and the reinforcing plate 424, the switch connecting rod 42 also includes a second mounting frame. The first mounting frame and the second mounting frame are respectively located on both sides of the reinforcing plate 424, and an elastic member for resetting the button 12 is installed on the second mounting frame.

[0064] In this embodiment, by arranging the first mounting frame and the second mounting frame on both sides of the reinforcing plate 424, it is helpful to improve the overall balance of the switch connecting rod 42. At the same time, the first mounting frame and the second mounting frame are respectively installed with the switch 41 and the elastic member, that is, the switch 41 and the elastic member are arranged horizontally, which is helpful to reduce the overall height of the host 1 and optimize the small space design of the host 1 compared with the existing solution in which the elastic member is arranged above the switch 41. More importantly, the elastic member in this solution has a multi-purpose effect. On the one hand, it can be used to reset the button 12, and at the same time, it can also reset the switch connecting rod 42. Compared with the solution in the prior art that a spring 426 needs to be set at the switch connecting rod 42, and an additional spring 426 is set at the button 12 to reset the button 12, the structure is simpler and the cost is lower.

[0065] Specifically, a horizontal flat plate is provided on the top surface of the rod body 423, and the reinforcing plate 424 is arranged perpendicular to the flat plate, and the reinforcing plate 424 is in the shape of a step 4231, so as to form a laterally extending support plate 427 at the surface of the step 4231, and the support plate 427 constitutes part of the second mounting frame. Then, an upward convex limiting rib 422 is provided on the top of the support plate 427, and the limited limiting rib 422 structure is a cross-crossing cross rib, and the elastic member is a spring 426, and the spring 426 is clamped on the limiting rib 422. In this scheme, by setting the laterally extending support plate 427, a flat platform is provided for the setting of the limiting rib 422. In this way, the spring 426 is clamped on the limiting rib 422, which is easy to install and has a longer service life than the cantilever structure used in the prior art. In addition, in the prior art, since the cantilever structure is integrated with the upper cover, it is difficult to ensure that the elastic force of the cantilever structure is consistent during the molding process. When the elastic force of the cantilever structure is less than the preset elastic force, the user needs to press the button 12 with great effort to trigger the switch 41, which is not a good experience. In this solution, there is no cantilever structure, and the elastic member uses a spring 426, which has good elasticity and reliability, and the user experience is better.

[0066] On the top surface of the bracket, there are two springs corresponding to the buttons (only for button reset), plus the spring on the switch connecting rod, a total of three springs, which are evenly distributed along the same circumference to provide better balance for the support of the buttons. Alternatively, there are three buttons, and each spring is located directly below the corresponding button.

[0067] In this embodiment, there is no specific limitation as to whether the first mounting frame is closer to the center of the bracket 51 than the second mounting frame, or whether the second mounting frame is closer to the center of the bracket 51 than the first mounting frame.

[0068] It can be understood that the reinforcing plate 424 in this embodiment can also be a vertical plate, that is, there is no step 4231 structure, and the support plate 427 is a horizontal plate extending laterally outward from the side of the reinforcing plate 424.

[0069] In a preferred embodiment of the present application, the first mounting frame is used to mount the switch 41, thereby achieving good fixation of the switch 41. On this basis, the present application further sets the first mounting frame toward the center of the bracket 51, so that the motor 13 and the switch 41 are close to being in a vertically facing position relationship, and the distance between the switch 41 and the motor 13 through the avoidance hole 53 is shorter, which reduces the cost of the wiring harness and effectively avoids the problem of entanglement when the connection is too long and the need for rolling and bundling. Specifically, for the above-mentioned embodiment 1, only the first mounting frame can be provided. Of course, in the case of a first mounting frame and a second mounting frame, the first mounting frame should be arranged closer to the center of the bracket 51 than the second mounting frame.

[0070] Further, in some embodiments of the present application, reference is made to Figure 5 and Figure 8 In order to better ensure that the switch link 42 will not be offset when moving axially along the avoidance hole 53, an axially extending guide groove 531 is provided on the inner circumferential wall of the avoidance hole 53, and a guide rib 421 matching the guide groove 531 is convexly provided on the outer circumference of the mounting bracket 51, so that the switch link 42 can only move axially along the guide groove 531. In addition, the cooperation between the guide groove 531 and the guide rib 421 also limits the circumferential rotation of the switch link 42 to a certain extent, and the switch 41 is triggered more reliably. The inner circumferential wall of the avoidance hole 53 is provided with an axially extending guide groove 531, and the outer circumference of the mounting bracket 51 is convexly provided with a guide rib 421 matching the guide groove 531.

[0071] Specifically, the guide ribs 421 are preferably arranged on both sides of the support plate 427. The guide ribs 421 include transverse ribs overlapped on the upper side of the support plate 427 and vertical ribs bent downward relative to the transverse ribs. The guide ribs 421 can be integrally formed with the support plate 427, or connected by gluing, screw fastening, etc. The guide groove 531 is provided on the peripheral wall of the avoidance hole 53, and the bottom wall of the bracket 51 also extends downward for a distance to extend the axial length of the guide groove 531, extend the guide distance, and achieve a better guide effect.

[0072] It is understandable that the guide rib 421 can also be arranged on the two side surfaces of the reinforcing plate 424, or on the outer side surface of the extension buckle 425. These conceivable arrangements should be included in the protection scope of this application.

[0073] In some embodiments of the present application, combined with Figure 1 , 29. The inner side wall of the housing 11 is provided with an axially extending limiting groove 111, in which the switch connecting rod 42 is accommodated, which plays a good guiding role for the circumferential movement of the switch connecting rod 42, and prevents the swing of the switch connecting rod 42 from affecting the triggering of the switch 41. Specifically, the limiting groove 111 is formed by two convex ribs arranged opposite to each other on the inner side wall of the housing 11.

[0074] Of course, whether the bottom end of the switch link 42 can accurately extend from or extend into the bottom of the housing 11 has a great impact on the user's experience. To this end, the present application also provides a guide column 112 protruding from the inner bottom wall of the housing 11, and the guide column 112 is provided with a through hole for the bottom of the switch link 42 to extend, so that the lower end of the switch link 42 is limited in the through hole of the guide column 112, and when the user installs the host 1, the switch link 42 will not be stuck; of course, when the user picks up the host 1, it can also avoid the situation where the switch link 42 cannot extend from the bottom wall of the housing 11.

[0075] Specifically, the guide post 112 is located between two convex ribs of the limiting groove 111 and is coaxially arranged with the limiting groove 111 to ensure centering and guiding performance of the rod body 423 .

[0076] In one embodiment of the present application, the bottom surface of the bracket 51 is provided with a buckle 511 extending downward, and the top of the motor 13 is provided with a metal frame 132, and the buckle 511 is clamped on the metal frame 132, so that the motor 13 is first fixed to the bracket 51, that is, the motor 13 and the decorative part 5 first form an integral part. Then, the integral part is fixedly connected to the housing 11 through the decorative part 5, so that the motor 13 is clamped and fixed between the bracket 51 and the bottom wall of the housing 11. For details, refer to Fig.10 The decorative part 5 and the housing 11 are fixedly connected by means of buckling: the bottom surface of the bracket 51 is provided with a lower buckling part 55 extending upward, and the top of the housing 11 is provided with an upper buckling part 14 extending upward. When the upper and lower buckling parts 55 are buckled in place, the bottom of the reduction box 133 of the motor 13 abuts against the inner bottom wall of the housing 11. Compared with the prior art, this solution also achieves the same fixing with the housing 11 without screws and is easy to install. It also improves the installation method. It only needs to position and install the integral part formed by the motor 13 and the decorative part 5 with the housing 11. The button 12 is directly installed on the top of the decorative part 5, eliminating the upper cover and lowering the cost.

[0077] Specifically, in the prior art, the host is disclosed to include an upper cover, a casing, and a motor assembly disposed in the casing, wherein the upper cover includes a cover body and a button mounted on the cover body in a snap-fit ​​manner, the motor assembly includes a motor and a motor bracket mounted in cooperation with the motor, and the micro switch is mounted on the top surface of the motor bracket. Specifically, the cover body is mounted in a snap-fit ​​manner with the casing to clamp the motor bracket, thereby clamping the motor between the upper cover and the casing. In the present application, the installation of the button and the parts mounted in cooperation with the motor are all completed by the bracket, which saves one accessory compared to the prior art, and the installation process and structure are simpler and the cost is lower. In addition, the switch of the present application is installed on a switch connecting rod, which is different from the switch installation method of the prior art. The switch connecting rod of the present solution directly drives the switch to move together, and the cooperation between the two is more stable.

[0078] It can be understood that the fixing connection method of the decorative member 5 and the housing 11 is not limited to the above-mentioned upper and lower buckle members 55 buckling method. Fig.11 A mounting hole may also be provided on the bracket 51, a radially inwardly convex portion is provided on the top of the shell 11, a countersunk hole with an upward opening is provided on the convex portion, and a fastening screw 56 passes through the mounting hole of the bracket 51 and the countersunk hole of the convex portion from top to bottom to lock and fix the decorative component 5 and the shell 11.

[0079] For further reference, Figures 1 to 4 The top of the bracket 51 is provided with a receiving cavity 512 into which the tail end of the output shaft of the power supply machine 13 is inserted, and the receiving cavity 512 is raised upward. The present application provides a receiving cavity 512 into which the tail end of the output shaft of the power supply machine 13 is inserted at the top of the bracket 51. The receiving cavity 512 is raised upward, which is beneficial to limiting the tail end of the motor 13 on the one hand, and is beneficial to reducing the overall height of the host 1 on the other hand, that is, the raised part will partially overlap with the switch 41.

[0080] Further, refer to Figure 2 A shock absorber 54 is sandwiched between the bottom surface of the bracket 51 and the top surface of the metal frame 132. The shock absorber 54 separates the motor 13 from the components above the top surface of the bracket 51 to prevent carbon powder from splashing onto the components. The shock absorber 54 separates the bracket 51 and the motor 13 to avoid hard contact. During operation, the vibration noise generated by the motor 13 is effectively alleviated by the shock absorber 54 to improve noise. The shock absorber 54 can be a silicone pad.

[0081] Preferably, in order to further reduce the working noise of the motor 13, a shock-absorbing pad 15 can also be provided on the outer bottom surface of the reduction box 133 and the inner bottom surface of the housing 11. The shock-absorbing pad 15 is sleeved on the output shaft of the reduction box 133. The inner bottom surface of the housing 11 is provided with a support frame extending upward. The center of the support frame is provided with a through hole for the output shaft to pass through. The shock-absorbing pad 15 is clamped between the outer bottom surface of the reduction box 133 and the support frame, so that the motor 13 is a flexible connection solution between the decorative part 5 and the housing 11. In addition, the shock-absorbing pad 15 also seals the gap between the through hole of the support frame and the output shaft, preventing water stains from entering the interior of the host 1, and achieving a waterproof effect.

[0082] In some aspects of this application, reference is made to Figure 3 , 4 The limiting column 513 on the bracket 51 is inserted into the limiting hole of the metal frame 132 to limit the motor 13 laterally and reduce the lateral deflection of the motor 13.
