[0019] In the embodiments of this application, the terms "first," "second," "third," "fourth," "fifth," and "sixth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," "third," "fourth," "fifth," and "sixth" may explicitly or implicitly include one or more of that feature.

[0020] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0021] Reference Figures 1 to 12 As shown in the figure, this application provides a water outlet pipe device, including a water vapor separator 100, a water outlet pipe structure 200, and a rotary drive assembly 300.

[0022] The water vapor separator 100 has a separation chamber 110 and at least one liquid inlet 120 communicating with the separation chamber 110. One end of the water outlet pipe structure 200 is located in the water vapor separator 100 and has a liquid inlet 210 communicating with the separation chamber 110. The other end of the water outlet pipe structure 200 has a liquid outlet 220 communicating with the liquid inlet 210.

[0023] At least a portion of the water outlet pipe structure 200 is telescopic, and when the water outlet pipe structure 200 is contracted, the water outlet pipe structure 200 is in a vertical liquid outlet state; the rotary drive assembly 300 is driven to cooperate with the water outlet pipe structure 200 to drive the water outlet pipe structure 200 to extend and twist, and switch the water outlet pipe structure 200 from a vertical liquid outlet state to a twisted and tilted liquid outlet state, and can drive the water outlet pipe structure 200 to return to a vertical liquid outlet state.

[0024] In a specific implementation, the water vapor separator 100 is set at the liquid inlet end of the water outlet pipe structure 200. A water inlet connector 140 can be set on the outer wall of the water vapor separator 100. One end of the water inlet connector 140 forms a liquid inlet 120, and the other end is connected to the separation chamber 110, so that water or coffee liquid or other liquids can be introduced into the separation chamber 110 through the water inlet connector 140.

[0025] For example, the outer wall of the water vapor separator 100 may be provided with, as shown in the example Figure 1 The two water inlet connectors 140 shown can be used, or one water inlet connector 140 can be provided.

[0026] In addition, an exhaust connector 130 communicating with the separation chamber 110 can be provided on the outer wall of the water vapor separator 100. One end of the exhaust connector 130 forms an exhaust port so that the gas separated from the liquid can be discharged through the exhaust connector 130, preventing the gas mixed in the liquid from flowing into the water outlet pipe structure 200 with the liquid and affecting the smooth flow of the liquid in the water outlet pipe structure 200.

[0027] Specifically, refer to Figure 4 As shown, the bottom of the water vapor separator 100 can be provided with a water outlet connector 101. The water outlet pipe structure 200 is sleeved on the water outlet connector, and the liquid inlet 210 of the water outlet pipe structure 200 is connected to the separation chamber 110. This facilitates reliable assembly between the water outlet pipe structure 200 and the water vapor separator 100. One end of the water blowing pipe structure forms a liquid inlet 210, and the other end forms a liquid outlet 220. This allows the liquid that enters the separation chamber 110 through the liquid inlet 120 to flow into the water outlet pipe structure 200 through the liquid inlet 210 and then out through the liquid outlet 220, eventually flowing into the container holding the liquid.

[0028] In this embodiment, at least a portion of the water outlet pipe structure 200 is extendable, and the initial state of the water outlet pipe structure 200 is the retracted state. For details, please refer to... Figure 1 and Figure 4The state shown is as follows. In the initial state, the retractable part of the water outlet pipe structure 200 is in a retracted state. At this time, the entire water outlet pipe structure 200 extends along the central axis of the liquid outlet 220, that is, it is in a state of vertical extension without bending or twisting. At this time, the liquid outlet surface of the liquid outlet 220 is parallel to the horizontal plane, so that the liquid discharged through the water outlet pipe structure 200 flows vertically downward.

[0029] When it is necessary to simulate the operation of manually rotating the water outlet to brew coffee, that is, when the extendable part of the water outlet pipe structure 200 needs to be able to twist and the liquid outlet surface of the liquid outlet 220 needs to be tilted relative to the horizontal plane, the water outlet pipe structure 200 can be driven by the rotation drive assembly 300 to cause the retractable part of the water outlet pipe structure 200 to extend and twist. At this time, while the retractable part is twisting, the liquid outlet 220 is tilted relative to the horizontal plane. See the specific reference. Figure 2 The diagram shows a twisted, tilted liquid outlet state. In this state, the liquid discharged from the outlet pipe structure 200 flows out at an angle, and as the outlet pipe structure 200 twists, the liquid flowing out through the outlet 220 rotates and flows out circumferentially along the inner wall of the container. When the liquid is coffee, this flow action effectively simulates the manual rotation of a hand while brewing coffee, catering to customer needs and enhancing the user experience. After use, the outlet pipe structure 200 can be reset to a vertical outlet state by rotating the drive assembly 300.

[0030] For example, the liquid outlet 220 is located at the top of the water outlet pipe structure 200, and the liquid inlet 210 is located at the top of the water outlet pipe structure 200, so that the liquid can flow out smoothly under the action of gravity. Specifically, when the water outlet pipe structure 200 is in an inclined liquid outlet state, the angle between the liquid outlet surface of the liquid outlet 220 and the horizontal plane can be any angle between 0° and 90°, which can be set according to actual needs.

[0031] The water outlet pipe device of this embodiment includes a water vapor separator 100, a water outlet pipe structure 200, and a rotary drive assembly 300. The water vapor separator 100 has a separation chamber 110 and at least one liquid inlet 120 communicating with the separation chamber 110. One end of the water outlet pipe structure 200 is located in the water vapor separator 100 and has a liquid inlet 210 communicating with the separation chamber 110. The other end of the water outlet pipe structure 200 has a liquid outlet 220 communicating with the liquid inlet 210, thereby forming a flow channel for liquid circulation. In this embodiment, at least a portion of the water outlet pipe structure 200 is extendable, and when the water outlet pipe structure 200 is contracted, it is in a vertical liquid outlet state. That is, at this time, the extendable portion of the water outlet pipe structure 200 is in a vertical contraction state, meaning the entire water outlet pipe structure 200 extends along the axial direction of the liquid inlet 210, and the liquid outlet surface of the liquid outlet 220 is parallel to the horizontal plane.

[0032] When it is necessary to switch the vertical water outlet pipe structure 200 to a twistable tilted liquid outlet state, a rotary drive component 300 is set to drive the constricted part of the water outlet pipe structure 200 to extend and twist, thereby switching the water outlet pipe structure 200 to tilted water outlet. At this time, as the extendable part of the water outlet pipe structure 200 extends and twists, the liquid outlet surface of the liquid outlet 220 is switched to a position perpendicular to the horizontal plane, simulating the operation of a human hand rotating to brew coffee. After use, it can be reset to the vertical liquid outlet state, thereby meeting different user needs.

[0033] Reference Figures 1 to 4 As shown, in some embodiments, the outlet pipe structure 200 includes a telescopic pipe assembly 230 and a first straight pipe 240 that are connected and communicated in sequence.

[0034] The end of the telescopic tube assembly 230 away from the first straight tube 240 is provided with an inlet 210 and connected to the water vapor separator 100, and the end of the first straight tube 240 away from the telescopic tube assembly 230 is provided with an outlet 220 and connected to the rotary drive assembly 300.

[0035] In a specific implementation, the water outlet pipe structure 200 may include two sections, namely the first straight pipe 240 and the telescopic pipe assembly 230. The telescopic pipe assembly 230 is used to make it telescopic, while the first straight pipe 240 is not telescopic. The setting of the first straight pipe 240 can prevent the turbulence phenomenon brought about by the telescopic pipe assembly 230, so as to avoid problems such as water splashing, loud water noise and unstable liquid flow caused by turbulence.

[0036] For example, the inner wall of the first straight pipe 240 is set to be a smooth inner wall, which can more effectively avoid turbulence.

[0037] At least a portion of the telescopic pipe assembly 230 is telescopic, and when the outlet pipe device is in the position of... Figure 1 In the initial state shown, at least part of the telescopic tube assembly 230 is in a contracted state. At this time, the entire telescopic tube assembly 230 and the first straight tube 240 extend along the central axis of the outlet 220, that is, in a vertically extending state. At this time, the outlet surface of the outlet 220 is parallel to the horizontal plane, so that the liquid discharged through the water outlet pipe structure 200 flows vertically downward.

[0038] When it is necessary to simulate the operation of manually rotating to brew coffee, that is, when the retractable part of the telescopic tube assembly 230 needs to twist and the outlet surface of the liquid outlet 220 needs to be tilted relative to the horizontal plane, the telescopic tube assembly 230 can be driven by the rotation drive assembly 300 to cause the retractable part of the telescopic tube assembly 230 to extend and twist. At this time, while the retractable part of the telescopic tube assembly 230 is twisting, it drives the first straight tube 240 to move, and finally makes the liquid outlet 220 on the first straight tube 240 tilt relative to the horizontal plane. See the specific reference. Figure 2 The diagram shows the twisted and tilted liquid dispensing state. In this state, the liquid discharged through the outlet 220 flows out at an angle and rotates around the inner wall of the container holding the liquid. When the liquid is coffee, the dispensing operation can well simulate the operation of manually rotating to brew coffee, thus meeting the needs of customers and improving the user experience.

[0039] Reference Figures 1 to 4 As shown, in some embodiments, the telescopic tube assembly 230 includes a telescopic tube 231 and a second straight tube 232 connected in sequence and in communication. The end of the second straight tube 232 away from the telescopic tube 231 is provided with a liquid inlet 210 and is connected to the water vapor separator 100. The end of the telescopic tube 231 away from the second straight tube 232 is connected to and in communication with the first straight tube 240.

[0040] In a specific implementation, the telescopic pipe assembly 230 includes a telescopic pipe 231 and a second straight pipe 232 that are connected and interconnected. The telescopic pipe 231 itself can be telescopic, that is, it can be compressed and extended. The second straight pipe 232 is not telescopic. The purpose of setting the second straight pipe 232 is to facilitate connection and assembly with the water vapor separator 100, and at the same time, it can avoid the problem of poor structural strength of the telescopic pipe assembly 230 due to the fact that the entire telescopic pipe assembly 230 is a telescopic structure.

[0041] For example, the telescopic tube 231 and the second straight tube 232 can be bonded or heat-fused together. The telescopic tube 231 and the first straight tube 240 can be bonded or heat-fused together.

[0042] In practice, the outer diameter of the telescopic tube 231 can be set to be the same as the outer diameter of the second straight tube 232. The outer diameter of the telescopic tube 231 is set to be greater than the outer diameter of the first straight tube 240. That is, as the liquid flows toward the outlet 220, the flow path of the liquid becomes narrower and narrower, which can increase the flow speed of the liquid and thus meet the liquid discharge requirements.

[0043] For example, the telescopic tube 231 is a flexible corrugated tube, such as a rubber corrugated tube or a silicone corrugated tube. The corrugated characteristics of the tube itself allow it to be stretched or compressed.

[0044] In some embodiments, the first straight pipe 240 and the second straight pipe 232 are non-flexible pipes, which allows the first straight pipe 240 and the second straight pipe 232 to have high structural strength and rigidity, so as to facilitate connection and assembly with the water vapor separator 100. At the same time, it facilitates the stable flow of liquid through the outlet 220 of the first straight pipe 240, avoiding the situation where the first straight pipe 240 is a flexible pipe and is prone to twisting under the impact of liquid, thus affecting reliable liquid discharge.

[0045] Furthermore, the telescopic pipe 231 will not collapse and interrupt the flow when twisted, thus affecting the water output. In addition, the telescopic pipe 231 itself has the ability to compensate for the displacement of the water outlet pipe structure 200 caused by thermal expansion and contraction or device movement when hot water is output.

[0046] Reference Figures 1 to 4 As shown, in some embodiments, the water outlet pipe structure 200 includes at least an inner pipe 250 and an outer pipe 260 sleeved outside the inner pipe 250. Both the inner pipe 250 and the outer pipe 260 are provided with an inlet 210 and an outlet 220, and at least a portion of the inner pipe 250 and at least a portion of the outer pipe 260 are retractable. The outer pipe 260 is connected to the rotary drive assembly 300 for transmission.

[0047] In specific implementation, the water outlet pipe structure 200 in this embodiment is a double-layer pipe structure, which can realize a dual-flow channel design. That is, the liquid can be set to flow out through the inner pipe 250, or through the outer pipe 260, or simultaneously through the inner pipe 250 and the outer pipe 260, to meet different liquid flow requirements.

[0048] In this embodiment, the inlet 210 and outlet 220 of the inner tube 250 and the outer tube 260 are independently set and do not affect each other. In this way, the inner tube 250 or the outer tube 260 can be flexibly selected for liquid discharge.

[0049] When the outlet pipe structure 200 is set as a double-layer pipe structure, in order to ensure that the double-layer pipe structure can reliably twist under the drive of the drive component, both the inner pipe 250 and the outer pipe 260 can be provided with retractable parts.

[0050] When the water outlet pipe device is in such a state Figure 1 In the initial state shown, both the retractable parts of the inner tube 250 and the outer tube 260 are in a contracted state. At this time, both the inner tube 250 and the outer tube 260 extend along the central axis of the outlet 220, that is, they are in a vertically extended compressed state. At this time, the outlet surfaces of the outlets 220 of the inner tube 250 and the outer tube 260 are parallel to the horizontal plane, so that the liquid discharged through the inner tube 250 or the outer tube 260 flows vertically downward.

[0051] When simulating the manual rotation of a coffee brewing machine, specifically when the constricted portions of the inner tube 250 and outer tube 260 need to extend and twist, causing the outlet surfaces of the inner and outer tubes 250 and 260 to tilt towards the horizontal, the outer tube 260 can be driven by the rotation drive assembly 300. The movement of the outer tube 260, in conjunction with the movement of the inner tube 250 within it, causes both the constricted portions of the inner and outer tubes 250 to extend and twist. Simultaneously, this twisting motion causes the outlet surfaces of the inner and outer tubes 250 and 260 to tilt relative to the horizontal. (See attached diagram). Figure 2 The diagram shows the twisted and tilted liquid dispensing state. In this case, the liquid discharged through the outlet 220 flows out at an angle and rotates around the inner wall of the container holding the liquid. When the liquid is coffee, the dispensing operation can well simulate the operation of manually rotating to brew coffee, in order to meet the user's needs and improve the user experience.

[0052] Reference Figures 1 to 4 As shown, in some embodiments, both the inner pipe 250 and the outer pipe 260 include a first straight pipe 240, a telescopic pipe 231 and a second straight pipe 232 connected in sequence. When the water outlet structure 200 is in a vertical liquid outlet state, the telescopic pipe 231 of the inner pipe 250 and the telescopic pipe 231 of the outer pipe 260 are staggered in the direction from the liquid inlet 210 to the liquid outlet 220.

[0053] Since the telescopic pipe 231 itself is formed by stacking multiple layers of folds, if the telescopic pipe 231 of the inner pipe 250 and the telescopic pipe 231 of the outer pipe 260 overlap to a certain extent in the vertical direction, it will result in a larger outer diameter of the entire outlet pipe structure 200, which is not conducive to achieving miniaturization design.

[0054] Reference Figure 5 As shown, in some embodiments, a first blocking structure 400 is provided inside the water vapor separator 100. The first blocking structure 400 extends circumferentially along the inner tube 250 and is located between the inner tube 250 and the outer tube 260 to separate the liquid inlet 210 of the inner tube 250 and the liquid inlet 210 of the outer tube 260.

[0055] In practice, when a small amount of liquid is introduced into the separation chamber 110, i.e. when a small flow rate of liquid is required, the liquid in the separation chamber 110 flows into the inner tube 250 through the inlet 210 and is finally discharged through the outlet 220 of the inner tube 250. That is, the liquid entering the inlet 210 of the inner tube 250 is blocked by the first blocking structure 400 and cannot flow to the inlet 210 of the outer tube 260. In other words, only the inner tube 250 allows liquid to flow while the outer tube 260 does not have any liquid flowing into it.

[0056] When a large amount of liquid is introduced into the separation chamber 110, i.e. when a large flow rate is required, the liquid in the separation chamber 110 flows into the inner tube 250 through the inlet 210. When the flow rate reaches the critical value, the liquid entering the inlet 210 of the inner tube 250 passes the first blocking structure 400 and flows to the inlet 210 of the outer tube 260. At this time, liquid is introduced into both the inner tube 250 and the outer tube 260, so that both the inner tube 250 and the outer tube 260 can discharge liquid into the container, thereby effectively increasing the discharge volume.

[0057] For example, the first blocking structure 400 can be a flange or a baffle, etc.

[0058] Reference Figure 5 As shown, in some embodiments, a second blocking structure 500 extending radially along the outer pipe 260 is provided inside the water vapor separator 100. The second blocking structure 500 is located at the liquid inlet 210 of the inner pipe 250 and the outer pipe 260. This arrangement can realize liquid intake and exhaust at the same time, ensuring that the gas in the inner pipe 250 and the outer pipe 260 can be effectively discharged, so as to ensure the smooth flow of liquid.

[0059] In other words, when the liquid flows into the inner tube 250 and the outer tube 260, the air originally in the inner tube 250 and the outer tube 260 must be expelled, otherwise air blockage will occur and the liquid will not be able to flow. Therefore, in this embodiment, a second blocking structure 500 is provided at the liquid inlet 210 of the inner tube 250 and the outer tube 260, which can effectively expel the gas.

[0060] For example, the second blocking structure 500 can be a baffle, a baffle plate, or a filter.

[0061] Reference Figures 6 to 12 As shown, in some embodiments, the rotary drive assembly 300 includes a drive member 310, a transmission assembly 320, and a linkage assembly 330.

[0062] The transmission assembly 320 is in transmission cooperation with the drive component 310, and the linkage assembly 330 is connected to the water outlet pipe structure 200 and cooperates with the transmission assembly 320. The drive component 310 is used to drive the transmission assembly 320 to rotate in a first direction so that the contraction part of the water outlet pipe structure 200 is extended and twisted through the linkage assembly 330, or to drive the transmission assembly 320 to rotate in a second direction opposite to the first direction so that the water outlet pipe structure 200 is reset to the vertical liquid outlet state through the linkage assembly 330.

[0063] When it is necessary to simulate the operation of manually rotating to brew coffee, that is, when the constricted part of the water outlet pipe structure 200 needs to be twisted and the liquid outlet surface of the liquid outlet 220 needs to be tilted relative to the horizontal plane, the drive component 310 can drive the transmission component 320 to rotate in the first direction. The rotation of the transmission component 320 is linked to the linkage component 330, which in turn causes the constricted part of the water outlet pipe structure 200 to extend and twist. At this time, the constricted part of the water outlet pipe structure 200, while twisting, causes the liquid outlet 220 to tilt relative to the horizontal plane. See the specific reference. Figure 2 The liquid is discharged at an angle as shown. In this case, the liquid discharged through the outlet 220 flows out at an angle and rotates around the inner wall of the container holding the liquid. When the liquid is coffee, the flow of the coffee liquid can well simulate the operation of a human hand rotating to brew coffee, so as to meet the user's needs and improve the user experience.

[0064] When it is not necessary to simulate the operation of human hand rotation for brewing coffee, the drive component 310 can drive the transmission component 320 to rotate in the second direction. The rotation of the transmission component 320 is linked to the linkage component 330, which in turn causes the linkage component 330 to link the contraction part of the water outlet pipe structure 200 to be compressed and in a vertical state, thereby realizing the switching of the vertical liquid outlet state.

[0065] For example, the first direction is counterclockwise, and the second direction is clockwise.

[0066] Reference Figure 6 , Figures 9 to 12 As shown, in some embodiments, the transmission assembly 320 includes at least two meshing first gears 321 and second gears 322, the first gears 321 being driven by the drive member 310 and the second gears 322 being driven by the linkage assembly 330.

[0067] In other words, the driving component 310 drives the first gear 321 to rotate, the rotation of the first gear 321 drives the second gear 322 to rotate in the first direction, and the rotation of the second gear 322 is linked to the linkage component 330, which in turn causes the linkage component 330 to extend and twist the constricted part of the water outlet pipe structure 200. At this time, the constricted part of the water outlet pipe structure 200 is twisted, causing the outlet 220 to tilt relative to the horizontal plane. See the specific reference. Figure 2 The tilted liquid discharge state is shown. Conversely, it will cause the water outlet pipe structure 200 to return to the vertical liquid discharge state with contraction.

[0068] Reference Figure 6 , Figures 9 to 12 As shown, in some embodiments, the linkage component 330 includes a support housing 331 and a linkage bushing 332 connected within the support housing 331.

[0069] The support housing 331 is sleeved on the second gear 322. The inner edge of the second gear 322 is provided with a receiving groove 323 with an opening facing the support housing 331. The other end of the water outlet pipe structure 200 passes through the linkage sleeve 332, and the outer wall of the linkage sleeve 332 is provided with an extension 333. The support housing 331 is provided with a clearance opening 334 for the extension 333 to extend out. The extension 333 is located in the receiving groove 323.

[0070] Along the first direction, the downstream side and the upstream side of the extension 333 are respectively provided with a first stop 325 and a second stop 326. When the water outlet pipe structure 200 is in the vertical liquid outlet state, the extension 333 is in contact with the second stop 326 and has a gap 327 with the first stop 325. The second gear 322 is provided with a circumferential notch 324 between it and the first stop 325.

[0071] In specific implementation, when the driving component 310 drives the first gear 321 to rotate, the second gear 322 meshes with the first gear 321 and rotates with the first gear 321. Since the inner edge of the second gear 322 is provided with a receiving groove 323, the outer wall of the linkage sleeve 332 through which the water outlet pipe structure 200 is provided with an extension 333. The extension 333 passes through the relief opening 334 on the support shell 331 and extends into the receiving groove 323.

[0072] When it is necessary to switch the water outlet pipe structure 200 to a torsional tilted liquid outlet state, the drive component 310 can be set to rotate in a first direction, such as counterclockwise. When the second gear 322 rotates, it drives the extension 333 to rotate towards the direction close to the circumferential notch 324, causing the linkage sleeve 332 with the extension 333 to tilt. See the specific reference. Figure 12 As shown, this causes the water outlet surface of the water outlet pipe structure 200 connected to the linkage sleeve 332 to tilt. As the second gear 322 rotates to contact the first stop 325 to provide a limiting function, i.e., when the size of the circumferential gap 324 between them becomes zero, the gap 327 between the extension 333 and the second stop 326 decreases or becomes zero. At this time, the rotation of the second gear 322 will drive the support housing 331 to rotate, and the rotation of the support housing 331 will drive the linkage sleeve 332 to rotate. At this time, the entire second gear 322, support housing 331 and linkage sleeve 332 rotate synchronously as a whole, thereby driving the water outlet pipe structure 200 to switch to the position shown. Figure 2 The diagram shows a twisted and tilted liquid dispensing state, in which the water outlet pipe structure 200 twists while tilting to dispense liquid, simulating the operation of a human hand rotating to brew coffee.

[0073] When it is necessary to reset the water outlet pipe structure 200 to the vertical liquid outlet state, the drive component 310 can be reversed, that is, rotated in the opposite direction to the first direction, such as clockwise, so that the final extension 330 is reset to the vertical position. Figure 11 The diagram shows the untilted state. The specific process is as follows: the second gear 322 reverses, causing the extension 330 to rotate away from the circumferential notch 324 and eventually abut against the second stop 326. At this time, the extension 333 rotates back to its original position. Figure 11 As shown in the non-tilted state, the water outlet pipe structure 200 connected to the linkage sleeve 332 returns to the vertical compression and vertical liquid outlet state.

[0074] It should be noted that when the water outlet pipe structure 200 is in a vertical liquid outlet state, the extension 333 is in a non-tilted state and located in the receiving groove 323. At this time, the extension 333 is just in contact with the second stop 326, which can restrict the extension 333 from continuing to rotate and tilting in the opposite direction. This can ensure that the extension 333 is reliably in a non-tilted state, so that the water outlet pipe structure 200 is reliably in a vertical liquid outlet state.

[0075] Specifically, extension posts can be provided at both ends of the linkage sleeve 332, and connection holes are provided at corresponding positions of the support shell 331. The connection posts are inserted into the connection holes to realize the connection between the linkage sleeve 332 and the support shell 331.

[0076] In addition, the water outlet pipe device is provided with an upper body 150 and a lower body 160, which together form a cavity. The water outlet pipe structure 200 is located in the inner cavity of the upper body 150, the water vapor separator 100 is located on the top of the upper body 150, the drive component 310 is located on the upper body 150, and the transmission component 320 and the linkage component 330 are located in the cavity. The bottom of the linkage component 330 is also provided with a bottom cover 170 connected to the lower body 160 and a bottom plug 190 located on the bottom cover 170. A corrugated plate 180 is provided between the bottom cover 170 and the linkage component 330 for pre-tightening assembly.
