[0047] This embodiment provides a cooking device with a steam cooking function and can realize automatic opening and closing of the cooking device door, thereby improving the reliability of the cooking device. The cooking device can be a cooking device with a steam cooking function such as a steamer, a steam-bake combination machine, etc.

[0048] like Figures 1 to 3 and Figure 9 As shown, the cooking device includes a body, a door 300, and a steam cooking module. The body includes an inner pot 600 with a cooking cavity with an opening at the front. The door 300 is movably mounted on the front side of the body and can open or close the front opening of the cooking cavity. The steam cooking module is used to provide hot steam into the cooking cavity to cook the food in the cooking cavity.

[0049] To facilitate steam discharge from the cooking cavity, the appliance also includes a hood 400 located on top of the inner pot 600. This hood 400 has a heat dissipation duct that communicates with the cooking cavity and has an exhaust port 401. During or after cooking, steam from the cooking cavity is discharged into the heat dissipation duct and then out through exhaust port 401. Furthermore, a heat dissipation fan 900 is located on top of the inner pot 600. This fan directs external cooling air into the heat dissipation duct and cools the hot steam, preventing overheating of the steam exiting the appliance and potentially scalding the user.

[0050] To achieve automatic door opening and closing of the cooking device, a lock assembly 200 is mounted on the top of the cooking device door 300. The cooking device body includes a mounting cavity located above the air hood 400 and separated from the heat dissipation duct. The cooking device also includes a door lock device 100, which comprises a drive assembly 1 and a door lock assembly 2. The door lock assembly 2 extends through the bottom of the mounting cavity. The first end of the door lock assembly 2 is located within the mounting cavity and is in transmission connection with the drive assembly 1. The second end of the door lock assembly 2 is located outside the mounting cavity and is configured to cooperate with the lock assembly 200. The drive assembly 1 drives the door lock assembly 2 to switch between an unlocked state, in which it can be disengaged from the lock assembly 200, and a locked state, in which it cooperates with the lock assembly 200 to lock the cooking device door 300.

[0051] The cooking device provided by the present invention can avoid the influence of hot steam in the heat dissipation duct on the driving component 1 because the driving component 1 is located in the installation cavity separated from the heat dissipation duct, thereby improving the safety and reliability of the use of the driving component 1; since the door lock component 2 passes through the bottom of the installation cavity, and the first end of the door lock component 2 can be located inside the installation cavity to facilitate the transmission connection between the door lock component 2 and the driving component 1, and the second end of the door lock component 2 can extend outside the body to facilitate the cooperation between the door lock component 2 and the lock component 200, thereby improving the setting convenience and use reliability of the door lock device 100.

[0052] In this embodiment, the lock component 200 is located in the middle of the door 300 along the left-right direction, and the door lock assembly 2 is located in the middle of the machine body along the left-right direction. The door lock assembly 2 passes through the bottom of the installation cavity, and the upper end of the door lock assembly 2 is located in the installation cavity and is transmission-connected to the drive assembly 1, while the lower end of the door lock assembly 2 is located outside the installation cavity. This improves the force balance during the opening and closing of the door 300 and ensures the door 300 closes reliably.

[0053] To further improve the rationality of the layout of the door lock device 100 in the installation cavity, in this embodiment, the drive assembly 1 is installed at one end of the installation cavity in the left-right direction, and the upper end of the door lock assembly 2 is connected to the drive assembly 1 via a transmission structure 3. Since the drive assembly 1 is installed at one end of the installation cavity in the left-right direction, it can effectively prevent the drive assembly 1 from interfering with other structures in the installation cavity, such as the fan cover 400, the heat dissipation fan 900, and the controller, thereby improving the rationality of the spatial layout of the structures in the installation cavity and ensuring that there is sufficient installation space for the drive assembly 1.

[0054] In this embodiment, the steam cooking module includes a steam generator 1200 and a water tank 1100. The steam generator 1200 is mounted on the rear side of the inner pot 600 and is used to provide hot steam to the inner pot 600. The water tank 1100 is connected to the steam generator 1200 to supply water to the steam generator 1200. The water tank 1100 and the drive assembly 1 are respectively mounted on the left and right sides of the installation cavity to avoid interference between the water tank 1100 and the drive assembly 1, further improving the local rationality of the structure within the installation cavity. The water tank 1100 and the steam generator 1200 can be configured with reference to the existing technology. This is not the focus of this utility model and will not be described in detail here.

[0055] To facilitate installation of the door lock assembly 2, the bottom of the installation cavity has a bottom structure 5031 that extends forward from the hood 400. This bottom structure 5031 is provided with a mounting hole 5032. The door lock assembly 2 rotates through the mounting hole 5032, with the portion of the door lock assembly 2 extending out of the installation cavity positioned in front of the hood 400. This arrangement allows the door lock assembly 2 to be positioned forward, facilitating its extension from the bottom of the installation cavity and positioning its lower end in front of the inner liner 600. This improves the ease with which the door lock assembly 2 and the lock component 200 fit together, reduces the size of the door lock assembly 2, and enhances its ease of installation. Furthermore, the front end of the hood 400 has an exhaust port 401 for the heat dissipation duct, with the door lock assembly 2 positioned in front of the exhaust port 401.

[0056] The machine body includes a chassis, which is positioned outside the inner liner 600. Specifically, the machine body includes a housing 1000 and a front frame 800. The front frame 800 is positioned around the front of the inner liner 600, with its upper end positioned higher than the inner liner 600. The housing 1000 wraps around the outer side of the inner liner 600 and forms the overall appearance of the machine body. The front sides of the inner liner 600 and the housing 1000 are both fastened to the front frame 800. A top support plate 700 is positioned at the top of the inner liner 600, and the air hood 400 is mounted on the upper side of the top support plate 700. A control panel 500 is mounted on the upper portion of the front frame 800. The control panel 500, the top of the air hood 400, and the housing 1000 form the aforementioned mounting cavity. The specific structure of the housing 1000, inner liner 600, top support plate 700, and door 300 can be determined with reference to existing technologies. This is not the focus of this invention and will not be described in detail here.

[0057] The machine body also includes a control panel 500, which is mounted to the upper end of the chassis via a panel bracket 503. The chassis, air hood 400, and control panel together form a mounting cavity. The panel bracket 503 includes a bottom structure 5031. Specifically, the control panel 500 is located above the inner liner 600 and extends forward from the front side of the inner liner 600. By placing the bottom structure 5031 on the panel bracket 503 of the control panel 500, the front side of the control panel 500 can be flush with the closed door 300. At the same time, the door lock assembly 2 can extend vertically downward from the bottom structure 5031, improving the installation convenience of the door lock assembly 2 on the bottom structure 5031 and simplifying its installation. Furthermore, by mounting the door lock assembly 2 on the panel bracket 503, the installation stability of the door lock assembly 2 is enhanced, reducing the possibility of the door lock assembly 2 becoming loose due to the pull of the door 300 when opening and closing the door.

[0058] Specifically, the control panel 500 also includes a control assembly 502 on a panel bracket 503 and a front panel 501 covering the front side of the control assembly 502. The panel bracket 503 is fastened to the front frame 800. The panel bracket 503 includes a vertically arranged front panel portion, the periphery of the front panel portion is folded backward to form a side panel portion, the side panel portion and the front panel portion together form an installation space, and an installation opening is provided on the front panel portion. The control assembly 502 is installed in the installation space, and the control components of the control assembly 502 are arranged opposite the installation opening to be exposed forward, and the front panel 501 is covered on the outer side of the front panel portion. The side panel portion located on the lower side of the front panel portion forms the above-mentioned bottom structure 5031. The specific structure of the control panel 500 can be set with reference to the existing technology. This is not the focus of this embodiment and will not be limited or elaborated on this time.

[0059] like Figures 5 to 7 As shown, to further enhance the ease of installation of the door lock assembly 2, the door lock assembly 2 includes a lock shaft 21 and a door hook 22. The lock shaft 21 vertically passes through the mounting hole 5032, and the upper end of the lock shaft 21 is in transmission connection with the drive assembly 1. The door hook 22 is mounted on the lower end of the lock shaft 21 and engages with the lock component 200. The provision of the lock shaft 21 and the door hook 22 reduces the space required for the door lock assembly 2 to rotate, thereby enhancing the ease of installation of the door lock assembly 2. Furthermore, since the lock shaft 21 vertically extends out of the bottom structure 5031, it facilitates the installation of the door lock assembly 2 through the bottom structure 5031, thereby reducing the size of the required mounting hole 5032.

[0060] In this embodiment, the lock shaft 21 is vertically arranged to improve the installation convenience of the lock shaft 21. In other embodiments, the lock shaft 21 can also be tilted relative to the vertical direction, such as the lock shaft 21 is tilted forward from top to bottom.

[0061] It is worth noting that the door hook 22 has a lock slot 221. When the door lock assembly 2 is in the unlocked state, the notch of the lock slot 221 faces forward, so that the lock component 200 can move in and out of the lock slot 221 along the front and rear directions, so that the machine door 300 can be opened relative to the machine body. When the door lock assembly 2 is in the locked state, the notch of the lock slot 221 faces left and right to limit the lock component 200 from moving forward and out of the lock slot 221.

[0062] Furthermore, a guide surface 222 is formed on the front side surface of the door hook 22, and the guide surface 222 is located on the front side of the lock slot 221 and extends forward from the notch of the lock slot 221 in a direction away from the notch of the lock slot 221. When the user closes the door and the door hook 22 is in a locked state, the lock component 200 first contacts the guide surface 222. During the process of the user closing the door, the lock component 200 pushes the guide surface 222 from front to back, causing the door hook 22 to rotate in the direction toward the unlocked state, and then guiding the lock component 200 to enter the lock slot 221 of the door hook 22, thereby realizing the user's manual door closing operation.

[0063] In this embodiment, the door lock device 100 also includes an elastic reset member. The driving component 1 drives the door lock member to rotate from the locked position to the unlocked position. The elastic reset member always applies an elastic force to the door lock member to rotate or maintain the door lock member to the locked position.

[0064] That is, when the door lock assembly 2 is not in action, the door lock component is maintained in the locked position under the elastic force of the elastic return component, and the machine door 300 is stably closed; when the door needs to be opened, the door lock assembly 2 is operated, so that the door lock assembly 2 drives the door lock component to rotate from the locked position to the unlocked position, the lock component 200 can be disengaged from the lock hook, and the user can perform the door opening operation; after the user opens the door, the door lock component returns to the locked position again under the elastic force of the elastic return component; when the user closes the door, the door lock component rotates to the unlocked position under the pressure of the lock component 200 so that the lock component 200 is stuck in the lock groove 221 of the lock hook; after the machine door 300 is closed, the door lock component returns to the locked position under the elastic force of the elastic return component.

[0065] It is worth noting that in this embodiment, the lower end of the door 300 is hingedly connected to the main body via a hinge mechanism. The hinge mechanism constantly applies an elastic force to the closed door 300, causing it to flip outward relative to the main body. Consequently, when the door lock device 100 and the lock component 200 are unlocked, the door 300 automatically flips outward under the elastic force of the hinge mechanism, achieving automatic opening of the door 300. This improves the convenience of opening the cooking device door and enhances the user experience and convenience of the cooking device. In other embodiments, the door 300 can only be opened manually by the user.

[0066] To further enhance the ease of installation of the door lock assembly 2, a lock base 4 is mounted on the upper side of the base structure 5031, and the lock shaft 21 is rotatably mounted on the lock base 4. The lock base 4 is preferably detachably connected to the base structure 5031, thereby facilitating the complete assembly and disassembly of the door lock device 100 from the housing and improving the ease of assembly and disassembly of the door lock device 100. Furthermore, a rotation axis hole is defined in the lock base 4, and the lock shaft 21 is rotatably inserted into the rotation axis hole and has a clearance fit therewith. In other words, the lock shaft 21 is radially limitedly engaged with the rotation axis hole to restrict radial movement of the lock shaft 21 within the rotation axis hole.

[0067] In order to achieve axial positioning of the lock shaft 21 and the lock seat 4, in this embodiment, a first axis limiter 25 is detachably provided on the upper end of the lock shaft 21, and the lock seat 4 is clamped between the bottom structure 5031 and the first axis limiter 25, that is, the first axis limiter 25 abuts against the side of the lock seat 4 away from the door hook 22, thereby limiting the downward movement of the lock shaft 21 relative to the lock seat 4.

[0068] Furthermore, a limiting ring portion 23 is protruding from the outer wall of the lock shaft 21, and the limiting ring portion 23 is located between the door hook 22 and the bottom structure 5031. The limiting ring portion 23 is restricted from passing through the mounting hole 5032, thereby preventing the lock shaft 21 from moving upward and penetrating into the mounting cavity as a whole, further improving the setting stability of the lock shaft 21, that is, improving the setting stability of the door lock assembly 2.

[0069] In order to improve the connection convenience between the door lock assembly 2 and the drive assembly 1, in this embodiment, the door lock assembly 2 further includes a connecting member 24 installed at the upper end of the door lock, and the connecting member 24 is transmission-connected to the drive assembly 1. The connecting member 24 is fixedly sleeved on the upper end of the lock shaft 21.

[0070] The upper end of the lock shaft 21 is detachably sleeved with a second shaft limiter 26, and the connecting member 24 is clamped between the first shaft limiter 25 and the second shaft limiter 26 to ensure the accuracy of the positional relationship between the lock shaft 21 and the connecting member 24, thereby better ensuring that the rotation of the connecting member 24 can reliably drive the lock shaft 21 to rotate, thereby ensuring the driving reliability of the drive component 1 on the door lock component 2.

[0071] In this embodiment, the lock shaft 21 includes a coaxially connected optical shaft segment and a screw segment. The optical shaft segment is inserted into the shaft through-hole, and a door hook 22 is connected to the end of the optical shaft segment away from the screw segment. The screw segment extends upward from the upper side of the lock seat 4. The first shaft stopper 25 and the second shaft stopper 26 are nuts that are threaded onto the screw segment. This simplifies the arrangement of the first shaft stopper 25 and the second shaft stopper 26. In other embodiments, the first shaft stopper 25 and / or the second shaft stopper 26 can also be a stopper sleeve that is provided on the lock shaft 21 with an interference fit, or a retaining spring that is fixed to the lock shaft 21, etc.

[0072] In this embodiment, the transmission structure 3 includes a connecting rod 32 and a slider 31. The slider 31 can be installed in the installation cavity so as to slide in the left and right directions. The first end of the connecting rod 32 is hinged to the slider 31, and the second end of the connecting rod 32 is hinged to the door lock assembly 2. The driving assembly 1 drives the slider 31 to slide so that the connecting rod 32 pushes the door lock assembly 2 to rotate. By setting the slider 31 and the connecting rod 32 as the transmission structure 3, the structural correlation between the door lock assembly 2 and the drive assembly 1 can be reduced, which is conducive to setting the length of the connecting rod 32 according to the positions of the door lock assembly 2 and the drive assembly 1, improving the structural versatility of the door lock assembly 2 and the drive assembly 1, and reducing the processing and design costs of the door lock device 100; at the same time, since the slider 31 slides in the left and right directions, the connecting rod 32 extends roughly in the left and right directions, so that when the drive assembly 1 pushes the slider 31 to slide, the force applied by the drive assembly 1 to the first end of the slider 31 is a force in the left and right directions, and when the machine door 300 is forced to open, the lock component 200 applies a force in the front and rear directions to the door lock unit, thereby reducing the transmission of the force of forcing the door to open to the slider 31 and the actuator assembly, reducing the probability of the machine door 300 being forced to open, and improving the safety of the door lock device 100 and the electrical appliance.

[0073] like Figure 4 and Figure 5 As shown, in other embodiments, the transmission structure 3 includes a connecting rod 32, a first end of which is connected to the driving assembly 1, and a second end of which abuts the upper end of the door lock assembly 2. The driving assembly 1 drives the connecting rod 32 to slide in the left-right direction, so that the connecting rod 32 pushes the door lock assembly 2 to rotate. In other words, in this arrangement, the connecting rod 32 is not connected to the door lock assembly 2 but only abuts against it.

[0074] Specifically, in this embodiment, the connecting rod 32 is hinged to the connecting member 24 of the door lock assembly 2 through the hinge shaft 7. The hinge shaft 7 is parallel to and spaced apart from the lock shaft 21, and the hinge shaft 7 is located on the rear side of the lock shaft 21 to avoid interference between the connecting member 24 and the control panel 500 on the front side of the lock shaft 21.

[0075] In this embodiment, the drive assembly 1 includes a drive motor 11 and a cam 12. The motor shaft of the drive motor 11 is vertically arranged and connected to the cam 12. The drive motor 11 drives the cam 12 to rotate, so that the rotation of the cam 12 pushes the slider 31 to slide in the left-right direction. The structure of this drive assembly 1 occupies a small space, is highly compact, and has low cost. In other embodiments, the drive assembly 1 may also adopt other existing structures that can achieve the left-right sliding of the slider 31. The specific structure of the drive assembly 1 is not limited by the present invention.

[0076] For the convenience of subsequent description, the rotation direction of the door lock assembly 2 from the locked state to the door lock position is called the first preset rotation direction, and the direction opposite to the first preset rotation direction is called the second preset rotation direction.

[0077] like Figures 5 to 8 As shown, in this embodiment, the driving assembly 1 drives the door lock assembly 2 to rotate about a first preset rotation direction, so that the door lock assembly 2 rotates from the locked state to the unlocked state. After the door lock assembly 2 rotates to the unlocked position, the elastic return member drives the door lock assembly 2 to rotate along a second preset rotation direction back to the locked position. The second preset rotation direction is opposite to the first preset rotation direction.

[0078] When the user closes the door, the lock component 200 contacts the guide surface 222 on the lock, causing the lock component 200 to push the door lock assembly 2 to rotate to the unlocked state, thereby closing the machine door 300 and locking the door hook 22 and the lock component 200 after the machine door 300 is closed. When the door lock assembly 2 rotates along the second predetermined direction from the unlocked state to beyond the predetermined locked state, the guide surface 222 of the door hook 22 deflects backward, causing the lock component 200 to contact other surfaces of the door hook 22 when closing the door, thereby preventing the lock component 200 from pushing the door lock assembly 2 from the locked state to the unlocked state, thereby causing the machine door 300 to be unable to close smoothly. The door hook 22 may also be damaged due to the machine door 300 squeezing the door hook 22, affecting the normal use of the door lock assembly 2.

[0079] To solve the above problem, in this embodiment, a limiting structure 5 is provided inside the mounting cavity, and the limiting structure 5 can abut against the door lock assembly 2 in the locked state to limit the door lock assembly 2 in the locked state from rotating along the second preset rotation direction, so that when the machine door 300 is restored from the unlocked state to the locked state, the door lock assembly 2 can abut against the limiting structure 5 to limit the door lock assembly 2 from continuing to rotate, causing the door lock assembly 2 to pass the locked state, thereby ensuring that the door lock assembly 2 is stably reset to the locked state during the reset process, thereby ensuring the reliability of the cooperation between the door lock assembly 2 and the lock component 200, and ensuring the door closing reliability and the reliability of the use of the door lock assembly 2.

[0080] In this embodiment, the limiting structure 5 is protruded from the lock base 4, which facilitates controlling the machining accuracy of the lock base 4 and the positional accuracy of the limiting structure 5 and the mounting shaft hole, thereby ensuring the positional accuracy of the limiting structure 5 and the door lock assembly 2 and the reliability of the limiting structure 5 in limiting the door lock assembly 2. In other embodiments, the limiting structure 5 can also be provided at other locations, such as at the bottom of the mounting cavity, specifically on the upper side of the bottom structure 5031.

[0081] Furthermore, when the door lock assembly 2 is rotated to the locked state, the connecting member 24 abuts against the limiting structure 5 , thereby improving the cooperation convenience between the limiting structure 5 and the door lock assembly 2 .

[0082] like Figure 9As shown, in this embodiment, the portion of the door lock assembly 2 that extends out of the mounting cavity is located within the airflow path of the heat dissipation duct. The door lock device 100 further includes a stop structure that blocks the airflow flowing through the door lock assembly 2 from flowing into the mounting cavity through the mounting hole 5032. By providing the stop structure, the airflow flowing through the door hook 22 in the heat dissipation duct can be blocked from flowing into the mounting cavity through the mounting hole 5032. This allows the door lock assembly 2 to be installed inside the mounting cavity while the door hook 22 extends outside the mounting cavity. This prevents steam in the heat dissipation duct from entering the mounting cavity through the mounting hole 5032, thereby preventing steam from corroding the door lock assembly 2 and other structures in the mounting cavity. This ensures the safety of the cooking device and improves the installation convenience of the door lock device 100.

[0083] In this embodiment, the stop structure includes a seal 6 and the aforementioned lock base 4. The seal 6 is sleeved on the outside of the lock shaft 21 and at least partially sandwiched between the lock base 4 and the bottom structure 5031. The seal 6 can seal the gap between the bottom structure 5031 and the lock base 4, preventing airflow from entering the installation cavity through the gap between the lock base 4 and the bottom structure 5031. Furthermore, the clearance between the lock shaft 21 and the rotating shaft hole ensures the reliability and smoothness of the rotation of the lock shaft 21 while also preventing airflow from entering the installation cavity through the gap between the rotating shaft hole wall and the lock shaft 21 due to the rotation shaft hole being too large.

[0084] In another embodiment, the stop structure includes only the aforementioned lock base 4, which is fitted and securely mounted to the bottom structure 5031. The fit of the lock base 4 to the bottom structure 5031 prevents airflow from entering the mounting cavity through the gap between the lock base 4 and the bottom structure 5031. In this embodiment, the seal 6 may not be provided.

[0085] In another embodiment, the door lock assembly 2 can be directly rotatably installed on the bottom structure 5031. At this time, the stop structure only includes the seal 6 but not the lock seat 4. The seal 6 is sleeved on the outside of the lock shaft 21, and the seal 6 blocks the gap between the hole wall of the mounting hole 5032 and the outer wall of the lock shaft 21, thereby blocking the airflow from entering the mounting cavity through the gap by blocking the gap between the hole wall of the mounting hole 5032 and the outer wall of the lock shaft 21.

[0086] To improve the installation stability and sealing reliability of the seal 6, in this embodiment, an annular retaining groove 62 is formed on the outer side of the seal 6, and the edge of the mounting hole 5032 is inserted into the retaining groove 62. The provision of the retaining groove 62 can improve the installation stability of the seal 6 in the mounting hole 5032, prevent the seal 6 from falling out of the mounting hole 5032, and thus better ensure the sealing reliability of the seal 6 in the gap.

[0087] Furthermore, the seal 6 is wrapped around the outside of the lock shaft 21 and rotates with the lock shaft 21, so that the seal 6 can seal the gap between the hole wall of the mounting hole 5032 and the lock shaft 21, preventing the airflow from flowing upward along the axial direction of the lock shaft 21 into the mounting cavity, further ensuring the sealing effect of the seal 6.

[0088] Since the seal 6 and the lock shaft 21 rotate in coordination, in order to ensure the sealing of the seal 6 while ensuring the smooth rotation of the lock shaft 21, the inner ring of the seal 6 has a shaft sealing ring portion 61, and the thickness of the shaft sealing ring portion 61 gradually decreases in the direction toward the lock shaft 21, thereby making the main structure thickness of the seal 6 relatively thick to facilitate the installation of the seal 6 on the bottom structure 5031, and the thickness of the part of the seal 6 that contacts the lock shaft 21 is relatively thin, so that the shaft sealing ring portion 61 can wrap the lock shaft 21, and the inner end of the shaft sealing ring portion 61 has a strong deformation ability, so that the setting of the shaft sealing ring portion 61 will not affect the rotation of the lock shaft 21, and can reduce the wear on the shaft sealing ring portion 61.

[0089] Furthermore, at least two shaft sealing rings 61 are provided at intervals along the axial direction of the lock shaft 21 to better ensure a sealing effect. In this embodiment, two shaft sealing rings 61 are provided, and the two shaft sealing rings 61 are located on opposite sides of the limiting groove 62 along the axial direction of the lock shaft 21, thereby simplifying the structure of the seal 6 while ensuring a sealing effect.

[0090] It is worth noting that when the stop structure only includes the seal 6, the matching structure between the seal 6 and the mounting hole 5032 and the lock shaft 21 can refer to the above-mentioned structure setting, that is, a limiting groove 62 is set on the outside of the seal 6 and a shaft sealing ring part 61 is set on the inside.

[0091] A sealing groove 41 is defined on the side of the lock base 4 facing the opening plane. This groove 41 communicates with the rotating shaft hole. One end of the seal 6 is positioned within the mounting hole 5032, and the other end is positioned within the sealing groove 41. The seal 6 forms a first sealing portion and a second sealing portion on opposite sides of the retaining groove 62. The first sealing portion is positioned within the mounting hole 5032, while the second sealing portion is squeezed into the sealing groove 41 and squeezed between the groove wall of the sealing groove 41 and the bottom structure 5031. This ensures that the seal 6 reliably seals the gap between the lock base 4 and the bottom structure 5031. Furthermore, the provision of the sealing groove 41 allows the lock base 4 and the bottom structure 5031 to be closely aligned, facilitating their secure installation. In other embodiments, the second sealing portion may be directly sandwiched between the bottom surface of the lock base 4 and the bottom structure 5031.

[0092] Furthermore, the sealing groove 41 is in a frustum shape, with its large end facing the mounting hole 5032. The second sealing portion is a frustum-shaped structure, and the peripheral side surface of the second sealing portion fits with the frustum surface of the sealing groove 41, thereby increasing the contact area between the groove wall of the sealing groove 41 and the second sealing portion, improving the extrusion effect of the groove wall of the sealing groove 41 on the second sealing portion, and ensuring the sealing effect.

[0093] Furthermore, the first sealing portion of the seal 6 is squeezed between the limiting ring portion 23 and the lower side of the bottom structure 5031. This arrangement allows the limiting ring portion 23 to squeeze the first sealing portion, thereby squeezing the limiting ring portion 23 against the shaft sealing ring portion 61, ensuring that the seal 6 reliably wraps around the lock shaft 21. At the same time, the cooperation between the limiting ring portion 23 and the seal 6 can limit the upward movement of the lock shaft 21 along its axial direction, ensuring the rotational reliability of the lock shaft 21.

[0094] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
