Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a food processing machine that operates stably. Background Technology

[0002] Existing food processing machines, such as grinders and soundproof blenders, typically include a main unit with a motor and an inner cup located above the main unit. The inner cup contains a stirring element connected to the motor. When using the food processor, the user places the ingredients into the inner cup, and the stirring element rotates at high speed driven by the motor to process the ingredients. However, this process generates considerable noise, especially from the grinding cup. The grinder's cup is usually made of steel, and the collision between the ingredients and the steel cup during grinding causes significant noise. Therefore, an effective noise reduction structure is needed for the inner cup. The conventional noise reduction structure on the market is to cover the inner cup with a detachable outer cover, which isolates the noise and reduces its propagation to the outside. When using the grinder, pressure is applied to the soundproof cover, which presses on a switch linkage. The switch linkage slides and presses on a microswitch at its bottom end, energizing the grinder and starting it to grind the food.

[0003] However, when the food processor is in its stored state and the user forgets to unplug it, the soundproof cover may be accidentally touched, triggering the main unit and causing it to start suddenly, which can be startling. To address this issue, the applicant's earlier patent application CN202320807531.6 discloses a safe food processor that uses a screw-on mechanism to trigger a microswitch, preventing accidental pressing of the outer cover from triggering the microswitch. Both of these microswitch triggering methods involve pressing or screwing on the cover, and both restrict the use of the outer cover. However, in most mainstream food processors, especially grinders, the inner cup is separate from the main unit. Users install the inner cup onto the main unit during food processing, and the inner cup connects to the mixing element via a connector, which in turn connects to the motor on the main unit to transmit torque. After processing, the inner cup can be removed from the main unit for cleaning, making it convenient to use. However, in actual use, users sometimes operate the outer cover and start the motor before the inner cup is properly installed. This can cause the upper and lower connectors to not mesh properly, resulting in relative friction and significant wear. Consequently, the lifespan of the entire machine is greatly reduced, seriously affecting the user experience. Utility Model Content

[0004] The purpose of this utility model is to provide a stable food processing machine to solve the problem of how to ensure that the outer cover can trigger the micro switch to start the motor after the inner cup is installed in place, while achieving sound insulation and noise reduction in a food processing machine with an outer cover installed on the outside of the inner cup.

[0005] To achieve the above objectives, this utility model provides a stable food processing machine, such as a grinder and a soundproof blender, including a main unit with a motor, an inner cup located above the main unit, and an outer cover covering the outer side of the inner cup. The inner cup contains a stirring component that is connected to the motor for transmission. The main unit contains a switch assembly for controlling the opening and closing of the motor. The switch assembly includes a first linkage assembly that cooperates with the outer cover and a second linkage assembly that cooperates with the inner cup. The first linkage assembly is unlocked only when the inner cup is installed in place and the second linkage assembly is driven to unlock the first linkage assembly, so that the first linkage assembly can move downward under the action of the outer cover to trigger the motor.

[0006] This application, by setting an inner cup above the main unit and an outer cover over the inner cup, allows users to place food in the inner cup for processing. After the outer cover is placed over the inner cup, it not only enables the motor to be turned on and off, but also provides sound insulation and noise reduction for food processing inside the inner cup. A noise reduction space is formed between the inner cup and the outer cover, reducing the transmission of noise to the outside and improving the user experience. The switching assembly includes a first linkage assembly that engages with the outer cover and a second linkage assembly that engages with the inner cup. When the user is processing food in the food processor, placing the food inside the inner cup and ensuring the inner cup is properly installed will cause the inner cup to drive the second linkage assembly to move and unlock the first linkage assembly. Only under these conditions can the user press the outer cover down, causing the first linkage assembly to move downwards and trigger the motor to operate, thus processing the food. This effectively prevents the outer cover from triggering the motor when the inner cup is not properly installed, which could prevent the motor from properly driving the mixing components and cause significant wear due to relative friction between the upper and lower connectors. This ensures smooth food processing, helps extend the lifespan of the upper and lower connectors, and improves the user experience.

[0007] In a preferred embodiment of a stable food processing machine, a locking notch is provided on the side of the first linkage assembly facing the second linkage assembly. The second linkage assembly includes an elastic link that moves laterally with the inner cup. The elastic link can be inserted into or disengaged from the locking notch to lock or unlock the first linkage assembly.

[0008] By providing a locking notch on the side of the first linkage assembly facing the second linkage assembly, and the second linkage assembly including an elastic link that moves laterally with the inner cup, the user can install the inner cup in place. This allows the inner cup to drive the elastic link to move laterally and disengage from the locking notch, thus removing the elastic link's vertical constraint on the first linkage assembly. This allows the outer cover to press down and drive the first linkage assembly to the trigger motor. Furthermore, when the inner cup is not in place, the elastic link can insert into the locking notch, thereby limiting the vertical movement of the first linkage assembly. This prevents the outer cover from moving downwards when pressed down, avoiding the situation where the motor is triggered before the inner cup is in place. This effectively prevents accidental motor triggering, improves the safety and reliability of the machine, ensures smooth food processing, and enhances the overall stability of the machine.

[0009] In a preferred embodiment of a stable food processing machine, the second linkage assembly further includes a drive rod disposed above the elastic link. The elastic link includes a limiting portion that engages with a locking notch and a mating portion that engages with the drive rod, with the mating portion extending obliquely upward. The drive rod has a drive surface that engages with the mating portion and extends obliquely upward.

[0010] By configuring the second linkage assembly to also include a drive rod located above the elastic linkage, the elastic linkage includes a limiting part that engages with the locking notch and a mating part that engages with the drive rod, with the mating part extending obliquely upward. The drive rod has a drive surface that engages with the mating part and extends obliquely upward, so that when the user installs the inner cup onto the main unit, as the inner cup moves downward, the inner cup can drive the drive rod to move downward. The drive surface on the drive rod forms a downward and lateral force on the mating part. Under the lateral left and right force, the elastic linkage moves away from the locking notch. When the inner cup is installed in place, the elastic linkage disengages from the locking notch under the drive of the drive rod, thereby losing its vertical limiting effect on the first linkage assembly. And when the inner cup is separated from the main unit, the elastic linkage can reset and insert into the locking notch to achieve vertical limiting effect on the first linkage assembly.

[0011] In a preferred embodiment of a stable food processing machine, the limiting part is a laterally extending limiting plate, the mating part is a mating plate that is connected to the limiting plate and extends upward at an angle, and the limiting plate and the mating plate are provided with upwardly extending surrounding plates on both sides.

[0012] By providing upward-extending enclosures on both sides of the limiting plate and the mating plate, the enclosures can position and guide the drive rod during its vertical movement, ensuring the stability of the engagement between the drive rod and the mating plate. This prevents the drive rod from detaching from the mating plate, which could cause the elastic link to become immobile, thus improving the stability of the linkage between the drive rod and the elastic link and ultimately enhancing the overall stability of the machine's operation.

[0013] In a preferred embodiment of a stable food processing machine, the inner cup is screwed onto the main unit. The elastic connecting rod includes a limiting part that cooperates with the locking notch and an upwardly extending driven part. The bottom end of the inner cup is provided with an active part that circumferentially abuts against the driven part. The active part can rotate with the inner cup and drive the driven part to move laterally so as to disengage the limiting part from the locking notch.

[0014] By configuring the elastic link to include a limiting part that engages with the locking notch and an upwardly extending driven part, and providing an active part at the bottom of the inner cup that circumferentially abuts against the driven part, when the user screws the inner cup onto the main unit, the active part can synchronously drive the driven part to move laterally as the inner cup rotates, thereby causing the limiting part to disengage from the locking notch. This allows the outer cover to drive the first link assembly to trigger the motor when pressed downwards. The elastic link can lock and unlock the first link assembly with a single component, resulting in a simpler structure and more stable and reliable operation. This helps to reduce the number of structural components in the entire machine and improve the compactness of the internal structure of the main unit.

[0015] In a preferred embodiment of a stable food processing machine, the switching assembly further includes a micro switch that cooperates with the first linkage assembly. The first bracket has a first mounting portion for accommodating the first linkage assembly and a second mounting portion for accommodating the micro switch. The first mounting portion is located above the second mounting portion, and the first mounting portion is vertically elastically connected to the first linkage assembly; or...

[0016] The first bracket and the second bracket are arranged side by side in a horizontal direction, and the first bracket is provided with a fixing part extending to the bottom of the second bracket. The switch assembly also includes a connector that passes through the fixing part and is fastened to the second bracket.

[0017] By providing a first mounting portion for accommodating the first linkage assembly and a second mounting portion for accommodating the micro switch, the first bracket can simultaneously fix the first linkage assembly and the micro switch, serving a dual purpose and enhancing its functionality. This eliminates the need for a separate structural component for fixing the micro switch, contributing to a more compact internal mechanism. Furthermore, the first mounting portion is located above the second mounting portion, and is vertically elastically connected to the first linkage assembly. This allows the outer cover to directly move the first linkage assembly downwards and trigger the micro switch when pressed down, while the first linkage assembly can return to its original position upwards after the outer cover detaches from the main unit.

[0018] In a preferred embodiment of a stable food processing machine, the main unit includes a main housing that houses a motor and a switching assembly. The top wall of the main housing is provided with a first clearance hole for a first linkage assembly to extend out and a second clearance hole for a second linkage assembly to extend out.

[0019] By providing a first clearance hole for the first link assembly to extend and a second clearance hole for the second link assembly to extend on the top wall of the main housing, the first link assembly can extend out of the main housing through the first clearance hole and be driven downward by the outer cover, while the second link assembly can extend out of the main housing through the second clearance hole and be driven downward by the inner cup, thus ensuring the stability of the whole machine operation.

[0020] In a preferred embodiment of a stable food processing machine, the top wall of the main housing is recessed to form a receiving groove, the inner cup is fixed in the receiving groove, a second clearance hole is formed in the bottom wall of the receiving groove, and a first clearance hole is formed in the outer side of the receiving groove.

[0021] By recessing the top wall of the main housing to form a receiving groove, the inner cup is fixed within the receiving groove. This allows the inner cup to be connected and secured to the main housing through the receiving groove, increasing the mating area between the main housing and the inner cup. This improves the stability of the connection between the inner cup and the main housing, preventing significant vibration and noise caused by unstable connection during processing, and further reducing noise generation. Simultaneously, a second clearance hole is formed on the bottom wall of the receiving groove, while the first clearance hole is formed on the outside of the receiving groove. This ensures that the receiving groove can only accommodate the inner cup, while the outer cover is located outside the receiving groove. This achieves a tight fit between the inner wall of the receiving groove and the side wall of the inner cup, further enhancing the stability of their fit.

[0022] In a preferred embodiment of a stable food processing machine, the top wall of the main housing is provided with a downwardly extending fixing portion, and the food processing machine also includes a fastener that passes through the switch assembly and is fastened to the fixing portion.

[0023] By providing a downwardly extending fixing part on the top wall of the main housing, the food processing machine also includes fasteners. The fasteners pass through the switch assembly and are fastened to the fixing part, thereby achieving the connection and fixation between the switch assembly and the main housing, improving the stability of the connection between the switch assembly and the main housing, and avoiding the situation where the stability of the switch assembly decreases after long-term use.

Detailed Implementation

[0034] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0035] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0036] like Figures 1 to 7As shown, this utility model provides a stable food processing machine, including a main unit 4 with a motor 5 inside, an inner cup 2 located above the main unit 4, and an outer cover 1 covering the outside of the inner cup 2. The inner cup 2 has a stirring component 3 that is connected to the motor 5 for transmission. The main unit 4 has a switch assembly for controlling the opening and closing of the motor 5. The switch assembly includes a first linkage assembly 7 that cooperates with the outer cover 1 and a second linkage assembly 6 that cooperates with the inner cup 2. The first linkage assembly 7 is unlocked only when the inner cup 2 is installed in place and the second linkage assembly 6 is driven to unlock the first linkage assembly 7, so that the first linkage assembly 7 can move downward under the action of the outer cover 1 to trigger the motor 5.

[0037] This application provides an inner cup 2 and an outer cover 1 that covers the outside of the inner cup 2, which allows users to place food in the inner cup 2 for processing. The outer cover 1 not only enables the motor 5 to be turned on and off, but also provides sound insulation and noise reduction for food processing inside the inner cup 2. A noise reduction space is formed between the inner cup 2 and the outer cover 1, reducing the transmission of noise to the outside and improving the user experience. Meanwhile, the switching assembly includes a first linkage assembly 7 that cooperates with the outer cover 1 and a second linkage assembly 6 that cooperates with the inner cup 2. When the user is processing food ingredients in the food processor, the food ingredients are placed in the inner cup 2. When the inner cup 2 is in place, the inner cup 2 will drive the second linkage assembly 6 to move and unlock the first linkage assembly 7. Only under this condition can the user press the outer cover 1 down and drive the first linkage assembly 7 down to trigger the motor 5 to work, thereby realizing the processing of food ingredients. This effectively avoids the situation where the outer cover 1 can trigger the motor 5 to work when the inner cup 2 is not in place, causing the motor 5 to fail to drive the stirring component 3 to rotate normally, and causing greater wear due to relative friction between the upper and lower connectors. This ensures the smooth processing of food ingredients, helps to extend the service life of the upper and lower connectors, and improves the user experience.

[0038] As a preferred embodiment of this application, such as Figure 3 , Figure 4 As shown, the first linkage assembly 7 has a locking notch 711 on the side facing the second linkage assembly 6. The second linkage assembly 6 includes an elastic link 62 that moves laterally with the inner cup 2. The elastic link 62 can be inserted into or disengaged from the locking notch 711 to lock or unlock the first linkage assembly 7.

[0039] By providing a locking notch 711 on the side of the first linkage assembly 7 facing the second linkage assembly 6, and the second linkage assembly 6 including an elastic link 62 that moves laterally with the inner cup 2, after the user installs the inner cup 2, the inner cup 2 can drive the elastic link 62 to move laterally and disengage from the locking notch 711. This causes the elastic link 62 to lose its vertical restriction on the first linkage assembly 7, allowing the outer cover 1 to press down and drive the first linkage assembly 7 to the trigger motor 5. When the inner cup 2 is not installed, the elastic link 62 can be inserted into the locking notch 711, thereby limiting the vertical movement of the first linkage assembly 7. This prevents the outer cover 1 from moving downward when pressed down, thus avoiding the situation where the motor 5 is triggered when the inner cup 2 is not installed. This effectively avoids the accidental triggering of the motor 5, improves the safety and reliability of the machine's operation, ensures the smooth processing of food ingredients, and enhances the stability of the entire machine.

[0040] It should be noted that this application does not specifically limit how the elastic link 62 achieves its action in this embodiment, and it can be any of the following embodiments:

[0041] Example 1: As Figure 3 , Figure 4 As shown, in this embodiment, the second linkage assembly 6 further includes a drive rod 61 disposed above the elastic link 62. The elastic link 62 includes a limiting part that cooperates with the locking notch 711 and a cooperating part that cooperates with the drive rod 61, and the cooperating part extends obliquely upward. The drive rod 61 is provided with a drive surface 611 that cooperates with the cooperating part and extends obliquely upward.

[0042] By configuring the second linkage assembly 6 to also include a drive rod 61 located above the elastic link 62, the elastic link 62 includes a limiting part that engages with the locking notch 711 and a engaging part that engages with the drive rod 61, with the engaging part extending obliquely upward. The drive rod 61 has a drive surface 611 that engages with the engaging part and extends obliquely upward, so that when the user installs the inner cup 2 onto the main unit 4, as the inner cup 2 moves downward, the inner cup 2 can drive the drive rod 61 to move downward. The drive surface 611 on the drive rod 61 forms a downward and lateral force on the engaging part. Under the lateral left and right force, the elastic link 62 moves away from the locking notch 711. When the inner cup 2 is installed in place, the elastic link 62 disengages from the locking notch 711 under the drive of the drive rod 61, thereby losing the vertical limiting of the first linkage assembly 7. And when the inner cup 2 is separated from the main unit 4, the elastic link 62 can reset and insert into the locking notch 711 to achieve the vertical limiting of the first linkage assembly 7.

[0043] It should be noted that, in this embodiment, the bottom of the inner cup 2 is provided with a downwardly extending rib, which can be a separate part from the drive rod 61. When the inner cup 2 is installed on the main unit 4, the rib moves downward with the inner cup 2 and drives the drive rod 61 to move downward. Of course, it can be understood that the rib itself can also be the drive rod 61. In this scheme, the outer wall of the rib is provided with an external thread to engage with the main unit, and the inner side of the bottom wall of the rib is provided with a drive surface facing the elastic connecting rod 62. When the inner cup 2 is installed on the main unit 4, the rib directly drives the elastic connecting rod 62 to move through the drive surface.

[0044] Furthermore, such as Figure 3 , Figure 4 As shown, the limiting part is a horizontally extending limiting plate 621, and the mating part is a mating plate 622 that is connected to the limiting plate 621 and extends upward at an angle. The limiting plate 621 and the mating plate 622 are provided with upwardly extending surrounding plates on both sides.

[0045] By providing upwardly extending enclosures on both sides of the limiting plate 621 and the mating plate 622, the enclosures can position and guide the drive rod 61 during its vertical movement, ensuring the stability of the engagement between the drive rod 61 and the mating plate 622. This prevents the drive rod 61 from disengaging from the mating plate 622, thus preventing the elastic connecting rod 62 from becoming immobile. This improves the stability of the linkage between the drive rod 61 and the elastic connecting rod 62, thereby enhancing the overall stability of the machine's operation.

[0046] Specifically, such as Figure 3 , Figure 4 As shown, the first linkage assembly 7 and the second linkage assembly 6 are arranged side by side. The first linkage assembly 7 includes a mating rod 71 forming a clearance notch and a trigger rod 72 connected to the mating rod 71 and extending upward. A micro switch 8 is located below the mating rod 71, and a first spring 73 is provided between the first bracket 74 and the mating rod 71 to allow the mating rod 71 and the trigger rod 72 to move up and down. At the same time, a second spring 63 is provided between the elastic link 62 and the second bracket 64 to allow the elastic link 62 to move laterally back and forth. Figure 3 As shown, in its natural state, the mating rod 71 and the trigger rod 72 are lifted by the force of the first spring 73, while the limiting plate 621 extends into the locking notch 711 under the force of the second spring 63. Since the top wall of the locking notch 711 abuts against the top wall of the limiting plate 621, the mating rod 71 and the trigger rod 72 are vertically limited, preventing the trigger rod 72 from moving downwards even when subjected to a downward force. Figure 4As shown, when the inner cup 2 is installed in place, the drive rod 61 moves downward, and the drive surface 611 exerts a downward and lateral force on the mating plate 622. Since the mating plate 622 and the bottom of the limiting plate 621 are supported by the second bracket 64, they can only move laterally and move away from the locking notch 711. After the limiting plate 621 is completely disengaged from the locking notch 711, the limiting plate 621 loses its vertical limitation on the mating rod 71. At this time, the outer cover 1 can drive the trigger rod 72 to move downward. When the outer cover 1 is installed in place, the bottom end of the mating rod 71 abuts against the micro switch 8, thereby triggering the micro switch 8.

[0047] Example 2: In this example, the inner cup 2 is screwed and installed with the main unit 4. The elastic connecting rod 62 includes a limiting part that cooperates with the locking notch 711 and an upwardly extending driven part. The bottom end of the inner cup 2 is provided with an active part that circumferentially abuts against the driven part. The active part can rotate with the inner cup 2 and drive the driven part to move laterally so as to drive the limiting part to disengage from the locking notch 711.

[0048] By providing a limiting part that engages with the locking notch 711 and an upwardly extending driven part on the elastic link 62, and an active part that circumferentially abuts the bottom of the inner cup 2, when the user screws the inner cup 2 onto the main unit 4, the active part can synchronously drive the driven part to move laterally as the inner cup 2 rotates, thereby causing the limiting part to disengage from the locking notch 711. This allows the outer cover 1 to drive the first link assembly 7 to trigger the motor 5 when pressed downwards. The elastic link 62 can lock and unlock the first link assembly 7 with just one component, making the structure simpler and the operation more stable and reliable. This helps to reduce the number of structural components in the whole machine and improve the compactness of the internal structure of the main unit 4.

[0049] Specifically, the main unit 4 includes a main unit housing 41 that houses the motor 5 and the switch assembly. The top wall of the main unit housing 41 is provided with a third clearance hole for the active part to extend into. The third clearance hole extends circumferentially along the main unit housing 41, and the driven part is located below the third clearance hole. When the user places the inner cup 2 from top to bottom onto the main unit housing 41, the active part is simultaneously inserted into the third clearance hole. When the inner cup 2 is tightened, the active part rotates circumferentially along the third clearance hole with the inner cup 2. When the inner cup 2 is about to be tightened into place, the active part abuts against the driven part. During the tightening process of the inner cup 2, the active part pushes the driven part to move circumferentially, and the limiting part can move together with the driven part. After the inner cup 2 is tightened into place, the limiting part also disengages from the locking notch 711, thereby unlocking the first linkage assembly 7. It should be noted that the setting of the active part in this application is not limited. It can be a rib extending downward from the bottom wall of the cup body, or a rib extending downward from the outer wall of the cup body, which will not be elaborated here.

[0050] As a preferred embodiment of this application, such as Figure 3 , Figure 4 As shown, the switch assembly includes a first bracket 74 that houses the first linkage assembly 7 and a second bracket 64 that houses the second linkage assembly 6, with the first bracket 74 and the second bracket 64 fixed together.

[0051] Furthermore, such as Figure 3 , Figure 4 As shown, the switch assembly also includes a micro switch 8 that cooperates with the first linkage assembly 7. The first bracket 74 is provided with a first mounting part 741 for accommodating the first linkage assembly 7 and a second mounting part 742 for accommodating the micro switch 8. The first mounting part 741 is located above the second mounting part 742, and the first mounting part 741 is vertically elastically connected to the first linkage assembly 7.

[0052] By providing a first mounting portion 741 for accommodating the first linkage assembly 7 and a second mounting portion 742 for accommodating the micro switch 8, the first bracket 74 can simultaneously fix the first linkage assembly 7 and the micro switch 8, serving a dual purpose and enhancing its functionality. This eliminates the need for a separate structural component to fix the micro switch 8, further improving the compactness of the internal mechanism of the main unit 4. Furthermore, the first mounting portion 741 is located above the second mounting portion 742, and is vertically elastically connected to the first linkage assembly 7. This allows the outer cover 1 to directly move the first linkage assembly 7 downwards and trigger the micro switch 8 when pressed downwards. Simultaneously, after the outer cover 1 detaches from the main unit 4, the first linkage assembly 7 can return to its original position.

[0053] It should be noted that this application does not specifically limit how the first support 74 and the second support 64 are connected. As one preferred embodiment of this application, such as... Figure 3 , Figure 4 As shown, the first bracket 74 and the second bracket 64 are arranged side by side in a horizontal direction, and the first bracket 74 is provided with a fixing part extending to the bottom of the second bracket 64. The switch assembly also includes a connector 9, which passes through the fixing part and is fastened to the second bracket 64.

[0054] As a preferred embodiment of this application, such as Figure 6 As shown, the host 4 includes a host housing 41 that houses the motor 5 and the switch assembly. The top wall of the host housing 41 is provided with a first clearance hole 411 for the first linkage assembly 7 to extend out and a second clearance hole 412 for the second linkage assembly 6 to extend out.

[0055] By providing a first clearance hole 411 for the first connecting rod assembly 7 to extend and a second clearance hole 412 for the second connecting rod assembly 6 to extend on the top wall of the main housing 41, the first connecting rod assembly 7 can extend out of the main housing 41 through the first clearance hole 411 and be driven downward by the outer cover 1, while the second connecting rod assembly 6 can extend out of the main housing 41 through the second clearance hole 412 and be driven downward by the inner cup 2, thus ensuring the stability of the whole machine operation.

[0056] Furthermore, such as Figure 6 , Figure 7 As shown, the top wall of the main housing 41 is recessed to form a receiving groove 413, the inner cup 2 is fixed in the receiving groove 413, the second clearance hole 412 is formed in the bottom wall of the receiving groove 413, and the first clearance hole 411 is formed in the outer side of the receiving groove 413.

[0057] By recessing the top wall of the main housing 41 to form a receiving groove 413, the inner cup 2 is fixed within the receiving groove 413. This allows the inner cup 2 to be connected and fixed to the main housing 4 through the receiving groove 413, which helps to increase the mating area between the main housing 4 and the inner cup 2, thereby improving the stability of the connection between the inner cup 2 and the main housing 4. This avoids the situation where the connection between the inner cup 2 and the main housing 4 is unstable during processing, which could lead to large vibrations and noise, and further reduces noise generation. At the same time, the second clearance hole 412 is formed on the bottom wall of the receiving groove 413, and the first clearance hole 411 is formed on the outside of the receiving groove 413. This ensures that the receiving groove 413 can only accommodate the inner cup 2, while the outer cover 1 is located on the outside of the receiving groove 413. This achieves a tight fit between the inner wall of the receiving groove 413 and the side wall of the inner cup 2, which helps to further improve the stability of the fit between the two.
