[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0029] In the description of this utility model, it should be understood that the terms "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more. In the description of this application, "and / or" means including three parallel solutions; taking "A and / or B" as an example, it includes solution A, or solution B, or a solution that simultaneously satisfies A and B.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] The following is for reference. Figures 1-3 This invention describes an access control device 100 according to an embodiment of the present invention.

[0032] like Figure 1 As shown, the access control device 100 according to an embodiment of the present utility model includes: an identification screen 20, a mounting bracket 10, and a cleaning component 40.

[0033] The application areas of the recognition screen 20 are not limited, and it can be used in the fields of smart home (such as smart mirrors), public safety (such as identity verification devices), access control systems (such as rapid identification and verification of people entering and exiting), and retail (such as self-checkout equipment).

[0034] The mounting bracket 10, with its stable support structure, ensures that the recognition screen 20 can operate stably in different environments. The height adjustment component 50 enhances the practicality and adaptability of the recognition screen 20, allowing users to adjust its height according to their needs.

[0035] It is worth noting that the type of mounting bracket 10 according to the embodiments of this application is not limited. It can be an independent frame structure, an independent column structure, or part of a wall, door, or other structure. This allows the access control device 100 to adapt to various installation environments and spatial layouts, improving the applicability and flexibility of the access control device 100. Once the type of mounting bracket 10 is determined, the distribution positions of the identification screen 20 and the cleaning component 40 can be adaptively designed.

[0036] In the following description of this application, the mounting frame 10 is described as an independent column structure. Those skilled in the art will readily understand, after reading the following description, that the mounting frame 10 can be implemented in other types of structures.

[0037] Optionally, the height adjustment component 50 can be a manual adjustment component or an electric adjustment component.

[0038] When the height adjustment component 50 is a manual adjustment component, the user can manually change the height of the recognition screen 20, which helps to improve the adaptability of the recognition screen 20.

[0039] When the height adjustment component 50 is an electrically adjustable component, the user can control the raising and lowering of the recognition screen 20 by operating the recognition screen 20, a remote control, or buttons.

[0040] like Figures 1-2 As shown, the cleaning component 40 is mounted on the mounting bracket 10, and the cleaning component 40 includes a cleaning part 42. When the height of the recognition screen 20 reaches a first set height range, the cleaning part 42 acts on the recognition screen 20, and when the recognition screen 20 reciprocates along the height direction within the first set height range, the cleaning part 42 repeatedly cleans the recognition screen 20.

[0041] Specifically, when the height of the recognition screen 20 is adjusted to the first set height range by the height adjustment component 50, the cleaning unit 42 will automatically start working, contact the recognition screen 20 and perform cleaning actions.

[0042] Within a first set height range, if the recognition screen 20 reciprocates along the height direction, the cleaning unit 42 reciprocates in the opposite direction. For example, if the recognition screen 20 begins to descend, the cleaning unit 42 will correspondingly form a movement trajectory opposite to the descent trajectory of the recognition screen 20, that is, the cleaning unit 42 will rise to ensure that it always maintains contact with the surface of the recognition screen 20 and performs cleaning. Conversely, if the recognition screen 20 rises, the cleaning unit 42 will descend, ensuring the cleaning effect on the recognition screen 20 in the same way.

[0043] In some alternative embodiments, the cleaning unit 42 may employ any of the following: soft bristles, a cleaning cloth, or a cleaning roller. The cleaning unit 42 may also be selected from other types of cleaning components depending on the material of the recognition screen 20 and the required level of cleanliness. Alternatively, the cleaning unit 42 may be an ultraviolet disinfection lamp. As the recognition screen 20 reciprocates, the ultraviolet disinfection lamp continuously irradiates the surface of the recognition screen 20, ensuring that each part receives thorough disinfection, guaranteeing uniformity and comprehensiveness of the disinfection.

[0044] In some embodiments, such as Figure 2 As shown, the cleaning assembly 40 further includes a liquid supply assembly 41. The liquid supply assembly 41 includes a liquid storage tank 411 and a liquid supply pipe 412, with the liquid storage tank 411 connected to the cleaning unit 42 via the liquid supply pipe 412. The access control device 100 further includes a triggering unit 30 for triggering the liquid supply assembly 41 to supply liquid.

[0045] The liquid storage tank 411 is responsible for storing cleaning or disinfecting solutions to ensure that they can be supplied to the cleaning unit 42 when needed. The liquid supply pipe 412 is the channel connecting the liquid storage tank 411 and the cleaning unit 42, ensuring that the cleaning unit 42 can obtain sufficient liquid supply during the cleaning or disinfection process.

[0046] The trigger unit 30 functions to provide a signal to the liquid supply assembly 41 to initiate the liquid supply process. The trigger unit 30 can provide the signal in various ways.

[0047] Optionally, the trigger unit 30 provides a physical signal. For example, it can trigger the liquid supply process by mechanically transmitting force. This triggering method is more intuitive and ensures the reliability of the access control device 100.

[0048] Optionally, the trigger unit 30 provides an electrical signal. For example, the status of the recognition screen 20 is monitored in real time by electronic sensors (such as photoelectric sensors, pressure sensors, position sensors, etc.). When the height of the recognition screen 20 reaches a first preset height range, an electrical signal is sent to the liquid supply assembly 41 to start the liquid supply process. This method of triggering by an electrical signal enables intelligent control.

[0049] In some embodiments, combined with Figure 2The trigger unit 30 is connected to the recognition screen 20. When the height of the recognition screen 20 reaches the second set height range and moves downward, the trigger unit 30 presses the liquid supply component 41 to drive the liquid supply component 41 to supply liquid.

[0050] The second set height range at least partially overlaps with the first set height range.

[0051] The second set height range mentioned here overlaps at least partially with the first set height range. This design ensures that the cleaning unit 42 receives a sufficient supply of liquid throughout the entire process of the recognition screen 20 moving downwards and contacting the cleaning unit 42, thereby enabling continuous and effective cleaning or disinfection.

[0052] Specifically, when the height of the recognition screen 20 enters the second preset height range, the trigger unit 30 begins to prepare for activation. Once the recognition screen 20 continues to move downwards, the trigger unit 30 presses the liquid supply component 41, causing the cleaning or disinfectant to flow through the liquid supply pipe 412 to the cleaning unit 42. Because the second preset height range overlaps with the first preset height range, the cleaning unit 42 receives a stable liquid supply throughout the entire process of contacting the recognition screen 20. This configuration not only improves the efficiency of cleaning or disinfection but also ensures the uniformity and continuity of cleaning or disinfection. Simultaneously, due to the tight integration of the trigger unit 30 and the recognition screen 20, the entire access control device 100 becomes more intelligent and automated, reducing the need for manual intervention and improving ease of use and security.

[0053] Alternatively, the second set height range may be higher than the first set height range. In this case, when the height of the recognition screen 20 reaches the second set height range, the trigger unit 30 will press the liquid supply component 41 to start the liquid supply process. Since the second set height range is higher than the first set height range, the cleaning unit 42 will begin to receive the cleaning liquid or disinfectant before the recognition screen 20 continues to move downward and is about to contact the cleaning unit 42.

[0054] In this way, the cleaning section 42 is already wetted with cleaning or disinfectant before the recognition screen 20 comes into contact with it, which ensures that an effective cleaning or disinfection process begins immediately upon contact.

[0055] In addition, without liquid, the contact between the cleaning unit 42 and the recognition screen 20 may generate dry friction, thereby damaging the surface of the recognition screen 20. This can be avoided by supplying liquid in advance.

[0056] In some embodiments, such as Figure 2As shown, the liquid supply assembly 41 includes a piston 413, a piston rod 414, and a push-button 415. The piston 413 is vertically movable within the liquid storage chamber 411. When the piston 413 moves downwards, it presses down on the liquid below. One end of the liquid supply pipe 412, connected to the liquid storage chamber 411, is always located below the piston 413. One end of the piston rod 414 is connected to the piston 413, and the other end is located outside the liquid storage chamber 411. The push-button 415 is connected to the end of the piston rod 414 located outside the liquid storage chamber 411. When the height of the recognition screen 20 reaches a second preset height range, the trigger part 30 contacts the push-button 415.

[0057] When the piston 413 moves downward, it pushes the liquid in the reservoir 411 downward, thereby generating pressure and causing the liquid to flow out through the supply pipe 412.

[0058] The edge of piston 413 is fitted against the inner wall of liquid reservoir 411. This ensures that liquid will not leak from liquid reservoir 411 when piston 413 moves upward.

[0059] The piston rod 414 transmits the movement of the piston 413 to the outside of the liquid reservoir 411, thereby controlling the up-and-down movement of the piston 413 via the push-button 415. Optionally, the piston rod 414 is made of corrosion-resistant and / or wear-resistant material. This type of piston rod 414 can withstand possible chemical corrosion and mechanical wear.

[0060] The push button 415 is connected to one end of the piston rod 414 outside the liquid reservoir 411. It is a component that can be contacted by the external trigger 30. When the height of the recognition screen 20 reaches the second set height range, the trigger 30 contacts the push button 415, thereby pushing the piston rod 414 downward, which in turn causes the piston 413 to move downward within the liquid reservoir 411, pressing down on the liquid below.

[0061] Optionally, the actuating part 415 and the piston rod 414 can be formed in one step. Of course, this invention is not limited to this; the actuating part 415 can also be formed after the piston rod 414 has been formed. In this case, the piston rod 414 and the actuating part 415 can be joined together after two processing steps. It is understood that regardless of the specific processing order of the piston rod 414 and the actuating part 415, it is acceptable as long as the piston rod 414 and the actuating part 415 form an integrated structure after the entire process is completed.

[0062] The liquid storage tank 411 is the main part of the liquid supply assembly 41, used to store cleaning fluid or disinfectant. The liquid storage tank 411 is made of corrosion-resistant material to ensure it can store liquid for extended periods without corrosion. The capacity of the liquid storage tank 411 can be customized to meet the needs of different scenarios.

[0063] One end of the supply pipe 412 is connected to the liquid storage tank 411, and the other end is connected to the cleaning section 42 that requires liquid supply. The end of the supply pipe 412 connected to the liquid storage tank 411 is always positioned below the piston 413 to ensure that liquid can flow out through the supply pipe 412 when the piston 413 moves downwards. Optionally, the supply pipe 412 is a flexible pipe. Such a flexible pipe allows for flexible adjustment of its position and shape as needed.

[0064] In some embodiments, the liquid supply assembly 41 further includes an elastic element 416. The elastic element 416 is sleeved on the piston rod 414, and the elastic element 416 abuts against the push part 415 and the liquid reservoir 411 respectively, so as to drive the push part 415 to drive the piston 413 to return to the upward position.

[0065] In the above technical solution, when the trigger part 30 contacts the push part 415 and pushes the piston 413 downward, the elastic member 416 is compressed and stores energy. Once the trigger part 30 separates from the push part 415 (for example, when the height of the recognition screen 20 rises and leaves the second set height range), the elastic member 416 releases the stored energy, pushes the push part 415 upward, and then drives the piston rod 414 and the piston 413 to reset upward.

[0066] By introducing the elastic element 416, the liquid supply assembly 41 has an automatic reset function. Without manual operation or other external power source, the piston 413 will automatically reset to the initial position after the trigger part 30 separates from the push part 415, ready for the next liquid supply operation.

[0067] Optionally, the elastic element 416 is a spring. The spring is sleeved outside the piston rod 414, with one end abutting against the top surface of the liquid storage tank 411 and the other end abutting against the bottom of the push part 415. This arrangement not only simplifies the structure and facilitates installation and maintenance, but also improves the stability and reliability of the liquid supply process.

[0068] In some embodiments, such as Figure 3 As shown, the cleaning assembly 40 also includes a bracket 60 connected to the mounting frame 10, and the cleaning part 42 is a cleaning roller rotatably mounted on the bracket 60.

[0069] The bracket 60 serves as a support structure for the cleaning roller and is tightly connected to the mounting frame 10 to ensure the stability and reliability of the cleaning roller.

[0070] Optionally, the bracket 60 is configured in an L-shape. One end of the L-shaped bracket 60 is connected to the mounting bracket 10. This ensures the stability and reliability of the overall structure. The other end of the L-shaped bracket 60 serves as a free end, where the cleaning roller is rotatably mounted. When the recognition screen 20 moves up and down in the vertical direction, the cleaning roller rolls on the surface of the recognition screen 20, effectively removing stains, dust, fingerprints, etc. from the recognition screen 20.

[0071] The cleaning roller is parallel to the recognition screen 20. This arrangement ensures that the cleaning roller can apply pressure evenly to the recognition screen 20 when it rolls, resulting in a more uniform and thorough cleaning effect.

[0072] The cleaning section 42 defines a receiving cavity, and the surface of the cleaning section 42 is provided with a liquid outlet for connecting to the receiving cavity. The liquid supply pipe 412 extends along the setting direction of the bracket 60 and connects to the receiving cavity.

[0073] The liquid outlet on the surface of the cleaning section 42 is a channel for liquid to flow out. It connects to the inside of the receiving cavity, ensuring that the liquid can flow evenly and stably to the surface of the cleaning section 42.

[0074] The liquid supply pipe 412 extends along the mounting direction of the bracket 60. This ensures that the liquid supply pipe 412 is stably fixed to the bracket 60, reducing the risk of displacement and damage to the liquid supply pipe 412, thereby reducing the possibility of liquid leakage.

[0075] Optionally, combined Figure 1 , Figure 3 The support 60 is constructed in a U-shape. The two ends of the U-shape are connected to the mounting frame 10, and the cleaning roller is rotatably connected to the middle of the U-shape. The U-shaped support 60 forms a stable support frame, which improves the stability of the support 60. Even if the recognition screen 20 reciprocates during the cleaning process, the cleaning roller can maintain close contact with the recognition screen 20, ensuring the uniformity and consistency of the cleaning effect.

[0076] The liquid supply tube 412 extends along both ends of the U-shaped support 60 to the cleaning section 42.

[0077] Optionally, there are two supply pipes 412, extending from both ends of the U-shaped support 60 to the cleaning section 42. Within the cleaning section 42, the two supply pipes 412 can be connected to different locations to achieve a more uniform liquid distribution. For example, one supply pipe 412 can be connected to one side of the cleaning roller, while the other is connected to the other side, allowing the cleaning liquid to be distributed more evenly on the cleaning roller, thereby improving the cleaning effect.

[0078] Access control device 100 according to some embodiments of the present utility model, such as Figure 3As shown, the height adjustment assembly 50 includes a guide rail 51, a slider 52, and a drive member 53. The guide rail 51 extends vertically and is mounted on the mounting bracket 10. The slider 52 is configured to be slidably connected to the guide rail 51, and the identification screen 20 is connected to the slider 52. The drive member 53 is used to drive the guide rail 51 or the slider 52 to move, so that the height of the identification screen 20 on the mounting bracket 10 is adjustable.

[0079] First, the guide rail 51 extends vertically to provide a stable track for the sliding of the slider 52. The design of the guide rail 51 ensures the linear movement of the slider 52, avoiding possible offset or wobbling during adjustment, and guaranteeing the accuracy and stability of the adjustment.

[0080] Secondly, the slider 52 is configured to be slidably connected to the guide rail 51. This design allows the slider 52 to slide up and down along the guide rail 51, thereby adjusting the height of the recognition screen 20 connected to the slider 52. The shape and size of the slider 52 match the guide rail 51 to ensure smooth and stable sliding.

[0081] Finally, the drive component 53 is a part used to drive the guide rail 51 or the slider 52 to move. Optionally, the drive component 53 can be any one of an electric motor, a hydraulic cylinder, or a pneumatic cylinder.

[0082] In some embodiments, the guide rail 51 is a lead screw with external threads on its surface. The slider 52 has internal threads that match the external threads of the lead screw, allowing the slider 52 to be slidably connected to the lead screw. A drive member 53 is located at one end of the lead screw and is used to drive the lead screw to rotate. When the drive member 53 is activated, it drives the lead screw to rotate, and the slider 52 slides up and down along the lead screw due to the interaction between the internal and external threads. In this way, the height of the recognition screen 20 connected to the slider 52 can be adjusted as needed.

[0083] In some existing access control devices, the screen is often set at a fixed angle, forcing shorter children or elderly people with disabilities to tilt their heads back to see the screen and perform facial recognition or other verification operations. This inconvenience may not only degrade the user experience but also lead to inaccurate recognition, thereby affecting the security of the access control system.

[0084] To solve the above problems, such as Figure 3As shown, the access control device 100 in some embodiments of this utility model further includes a base 70 and a telescopic rod 80. The base 70 is connected between the recognition screen 20 and the height adjustment component 50, and the side of the base 70 away from the height adjustment component 50 is hinged to one end of the recognition screen 20 via a hinge seat 201. The two ends of the telescopic rod 80 are respectively hinged to the recognition screen 20 and the base 70. The telescopic rod 80 extends and retracts, causing the recognition screen 20 to rotate around the hinge seat 201, thereby changing the angle of the recognition screen 20 relative to the base 70.

[0085] The base 70 is used to connect the recognition screen 20 and the height adjustment component 50. It is located between the recognition screen 20 and the height adjustment component 50 and acts as a bridge.

[0086] On the side of the base 70 furthest from the height adjustment assembly 50, a hinge is established between the base 70 and one end of the recognition screen 20 via a hinge seat 201. This connection allows the recognition screen 20 to rotate around the hinge seat 201, providing a basis for angle adjustment.

[0087] The telescopic rod 80 is a key component for adjusting the angle of the recognition screen 20, with its two ends hinged to the recognition screen 20 and the base 70, respectively. This design allows the telescopic rod 80 to drive the recognition screen 20 to rotate around the hinge seat 201 during the extension and retraction process, thereby changing the angle of the recognition screen 20 relative to the base 70.

[0088] In practical applications, when the tilt angle of the recognition screen 20 needs to be adjusted, it is simply a matter of rotating the recognition screen 20 around the hinge base 201 by extending and retracting the telescopic rod 80. This adjustment method is simple and intuitive, allowing users to easily adjust the angle of the recognition screen 20 according to their needs to achieve the best visual effect. Furthermore, due to the cooperation between the telescopic rod 80 and the hinge base 201, the angle adjustment of the recognition screen 20 not only has a large range but also allows for precise fine-tuning. This enables the access control device 100 to adapt to more diverse user needs. For shorter children, the telescopic rod 80 can be extended to tilt the recognition screen 20 downwards to accommodate their angle, making it easier for children to perform facial recognition or other verification operations, thereby improving recognition efficiency and accuracy. Similarly, for elderly or physically disabled users, they can adjust the angle of the recognition screen 20 according to their comfort, improving the flexibility and applicability of the access control device 100.

[0089] In some embodiments, such as Figure 3 As shown, the recognition screen 20 has a card slot 202 that extends along the height direction, and one end of the telescopic rod 80 is slidably connected to the card slot 202 through a card block 203.

[0090] This configuration allows the telescopic rod 80, under the action of driving force, to adjust the angle of the recognition screen 20 by sliding the locking block 203 within the locking slot 202. When the telescopic rod 80 extends, the locking block 203 slides downward within the locking slot 202, thereby pushing one end of the recognition screen 20 downward, achieving downward rotation of the recognition screen 20. Conversely, when the telescopic rod 80 shortens, the locking block 203 slides upward within the locking slot 202, causing one end of the recognition screen 20 to lift upward, achieving upward rotation of the recognition screen 20.

[0091] Since the slot 202 extends along the height direction, the telescopic rod 80 can be extended and retracted within a large range to meet the needs of users of different heights.

[0092] Furthermore, the connection between the card slot 202 and the card block 203 has a self-locking function. Therefore, when the telescopic rod 80 stops extending or retracting, the friction between the card block 203 and the card slot 202 locks the identification screen 20 at its current angle position, preventing it from moving or shaking on its own. This self-locking function not only improves the safety of the access control device 100 but also reduces changes in the angle of the identification screen 20 caused by misoperation or external interference.

[0093] In some embodiments, such as Figures 1-2 As shown, the mounting bracket 10 has an access port 11, and the access port 11 has an openable and closable access door 12. The access port 11 is provided to facilitate the maintenance, repair, and replacement of parts of the access control device 100.

[0094] The access door 12 is fixed to the mounting bracket 10 by hinges or other connection methods, allowing the access port 11 to be easily opened and closed. The access door 12 ensures the sealing performance of the access control device 100, preventing external factors such as dust and moisture from affecting the internal components of the access control device 100, while also facilitating opening and closing by maintenance personnel.

[0095] The following is for reference. Figure 1 - Figure 3 The access control device 100 according to an embodiment of the present invention is described in detail with reference to a specific example. It is to be understood that the following description is merely illustrative and not intended to limit the scope of the invention.

[0096] Reference Figures 1-3 The access control device 100 includes: a mounting bracket 10, an identification screen 20, a trigger 30, a cleaning component 40, a height adjustment component 50, a bracket 60, a base 70, and a telescopic rod 80.

[0097] The identification screen 20 is connected to the base 70.

[0098] Reference Figure 3 The recognition screen 20 includes: a hinge base 201, a card slot 202, and a card block 203.

[0099] The hinge base 201 is located at the lower edge of the recognition screen 20.

[0100] The slot 202 is located above the hinge seat 201 and extends along the height direction. The locking block 203 is slidably disposed within the slot 202.

[0101] The lower part of the recognition screen 20 is hinged to the base 70 via a hinge seat 201.

[0102] The two ends of the telescopic rod 80 are respectively hinged to the card block 203 on the recognition screen 20 and the base 70.

[0103] The telescopic rod 80 extends and retracts, causing the recognition screen 20 to rotate around the hinge seat 201, thereby changing the angle of the recognition screen 20 relative to the base 70.

[0104] The height adjustment component 50 is mounted on the mounting bracket 10 and connected to the base 70 so that the height of the recognition screen 20 relative to the mounting bracket 10 is adjustable.

[0105] Reference Figure 3 The height adjustment component 50 includes: a guide rail 51, a slider 52, and a drive component 53.

[0106] The guide rail 51 extends vertically and is mounted on the mounting bracket 10.

[0107] The slider 52 is configured to be slidably connected to the guide rail 51, and the recognition screen 20 is connected to the slider 52 via the base 70.

[0108] The drive unit 53 is used to drive the guide rail 51 to move so that the height of the recognition screen 20 on the mounting bracket 10 is adjustable.

[0109] The bracket 60 is mounted on the mounting frame 10, and the cleaning part 42 is a cleaning roller that is rotatably mounted on the bracket 60.

[0110] When the height of the recognition screen 20 is adjusted to the first set height range, the cleaning unit 42 acts on the recognition screen 20, and when the recognition screen 20 moves back and forth along the height direction within the first set height range, the cleaning unit 42 repeatedly cleans the recognition screen 20.

[0111] Reference Figure 2 The cleaning component 40 is mounted on the mounting bracket 10. The cleaning component 40 includes a liquid supply component 41 and a cleaning section 42.

[0112] The liquid supply assembly 41 is used to supply liquid to the cleaning section 42.

[0113] Reference Figure 2 The liquid supply assembly 41 includes: a liquid storage tank 411, a liquid supply pipe 412, a piston 413, a piston rod 414, a pressing part 415, and an elastic element 416.

[0114] The piston 413 is vertically movable within the liquid storage chamber 411. When the piston 413 moves downward, it presses down on the liquid in the lower part of the liquid storage chamber 411. One end of the liquid supply pipe 412 is connected to the lower end of the liquid storage chamber 411, ensuring that the connection point is always located below the piston 413. The other end of the liquid supply pipe 412 extends along the mounting bracket 10 to the support 60 and communicates with the interior of the cleaning section 42.

[0115] The cleaning section 42 has a defined receiving cavity, and the surface of the cleaning section 42 is provided with a liquid outlet for connecting to the receiving cavity. The liquid supply pipe 412 is connected to the receiving cavity.

[0116] One end of the piston rod 414 is connected to the piston 413, and the other end is located outside the liquid storage chamber 411.

[0117] The push part 415 is connected to the end of the piston rod 414 located outside the liquid storage tank 411.

[0118] The trigger unit 30 is mounted on the base 70. When the height of the recognition screen 20 is adjusted, the trigger unit 30 can be moved up and down.

[0119] When the height of the recognition screen 20 reaches the second set height range and moves downward, the trigger part 30 presses the actuating part 415 to drive the liquid supply assembly 41 to supply liquid.

[0120] The second set height range at least partially overlaps with the first set height range.

[0121] The elastic element 416 is sleeved on the piston rod 414 and abuts against the push part 415 and the liquid reservoir 411 respectively, so as to drive the push part 415 to drive the piston 413 to return to the upward.

[0122] The mounting bracket 10 has an access port 11, and the access port 11 has an openable and closable access door 12.
