[0036] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0038] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0039] Example 1

[0040] Reference Figure 1-5This is the first embodiment of the present invention, which provides a smart cabinet for storing tickets using facial recognition, including a storage component 100, which includes a cabinet box 101, a facial recognition smart display screen 102 disposed on one side of the cabinet box 101, and multiple cabinets 103. The facial recognition smart display screen 102 is equipped with a facial camera that recognizes the user's face, and a high-speed door controller that drives the cabinet door to open and close is installed on the cabinet 103. The cabinet 103 also has a cavity for accommodating tickets. The facial recognition smart display screen 102 is connected to a backend server via a wireless module or network cable. Next, staff can create a database of facial photos of ticket recipients. The facial recognition smart display screen 102 can automatically verify the identity of the ticket recipient through a facial recognition program, and then quickly and accurately find the matching cabinet 103 through facial recognition search, automatically open the cabinet door, and retrieve the ticket, which is highly efficient. The cabinet door and cabinet 103 are connected by a high-speed door controller, which can be set to open and close the door at a time or automatically open and close the door according to specific conditions, so that users can retrieve their tickets in the corresponding cabinet 103 after operating the facial recognition smart display screen 102.

[0041] A dehumidification assembly 200 is disposed in the cavity to remove moisture from inside the cavity. The dehumidification assembly 200 includes a drawer 201 slidably disposed on the cavity, with a dehumidification bag 202 placed on top of the drawer 201. A trigger 203 is provided above the dehumidification bag 202 to detect the degree of expansion of the dehumidification bag 202. When the dehumidification bag 202 reaches a preset expansion range, the trigger 203 pushes the drawer 201 to a preset position and transmits a signal to the face recognition smart display screen 102. A limit member 204 is provided on the trigger 203 to constrain the rotation of the trigger 203. The dehumidification bag 202 can absorb moisture from the cabinet 103. The dehumidification bag 202 will expand accordingly during the moisture absorption process. When the dehumidification bag 202 expands to a preset range, it will push the trigger plate 203a to rotate to a preset angle, so that the drawer 201 can automatically pop out when the dehumidification bag 202 has absorbed the maximum moisture, which not only facilitates replacement but also serves as a reminder.

[0042] Furthermore, the trigger 203 includes a trigger plate 203a, the first end of which is located above the dehumidifying bag 202, and the second end of which is rotatably connected to the cabinet 101 via a pivot. A first torsion spring 203d is sleeved on the pivot portion of the trigger 203. The trigger 203 also includes a drive gear 203b rotatably connected to the cabinet 101. A toothed groove that meshes with the drive gear 203b is provided on one side of the drawer 201, and a second torsion spring is sleeved on one end of the drive gear 203b. The limiting component 204 includes a first ratchet 204a fixed coaxially with the drive gear 203b. A first pawl 204b is provided on one side of the first ratchet 204a to limit the first ratchet 204a in one direction. The first pawl 204b is rotatably connected to the cabinet 101, and a spring is fixedly connected between the first pawl 204b and the cabinet 101. A control rope 204c is wound around the first pawl 204b and the rotating shaft of the trigger plate 203a. During the moisture absorption process, the dehumidifying bag 202 will expand accordingly. When the dehumidifying bag 202 expands to a preset range, it will push the trigger plate 203a to rotate to a preset angle. Therefore, the trigger plate 203a drives the control rope 204c to pull the first pawl 204b to rotate through the rotating shaft, so that the first pawl 204b separates from the first ratchet 204a. At this time, the drive gear 203b loses its constraint and rotates under the action of the second torsion spring. Therefore, the drive gear 203b pushes the drawer 201 to move outward through the tooth groove, so that the drawer 201 can automatically pop out when the dehumidifying bag 202 absorbs the maximum moisture.

[0043] Currently, after the business hall schedules an appointment for customers who need paper invoices in advance, the customers still need to go to the business hall, queue up according to their number, provide a letter of authorization and the agent's ID card, and undergo manual verification before they can sign for and receive the invoice. Sometimes, customers forget to bring the relevant invoice collection documents and cannot receive the invoice, which seriously affects the customer experience.

[0044] To solve the above problems, by adding a storage component 100 and a dehumidification component 200, the identity of the ticket collector can be accurately and quickly verified by "face recognition". After the cabinet 101 opens the matching cabinet 103, the ticket can be collected by the user without queuing. The dehumidification bag 202 can also be replaced in time when the moisture absorption reaches its maximum value, thereby effectively preventing the tickets from getting damp and sticking together.

[0045] Specifically, the facial recognition smart display screen 102 connects to the backend server via a wireless module or network cable. Staff can create a database of facial photos of ticket recipients. The facial recognition smart display screen 102 can automatically verify the identity of the ticket recipient through a facial recognition program, and then quickly and accurately find the matching cabinet 103 through facial recognition search, automatically opening the cabinet door to retrieve the ticket, which is highly efficient. The cabinet door and cabinet 103 are connected through a high-speed door controller, which can be set to open and close the door at a time or automatically open and close the door according to specific conditions. This allows users to retrieve their tickets from the corresponding cabinet 103 after operating the facial recognition smart display screen 102, which is highly secure, simple to operate, and allows them to retrieve tickets by scanning their faces, achieving accurate and fast functionality.

[0046] Meanwhile, the dehumidifier bag 202 absorbs moisture from the cabinet 103, effectively preventing the paper from sticking together due to moisture. The dehumidifier bag 202 expands during the absorption process. When it expands to a preset range, it pushes the trigger plate 203a to rotate to a preset angle. The trigger plate 203a then drives the control rope 204c via a rotating shaft, pulling the first pawl 204b to rotate, causing it to separate from the first ratchet 204a. At this point, the drive gear 203b, no longer constrained, rotates under the action of the second torsion spring. This drive gear 203b then pushes the drawer 201 outwards through its tooth grooves, allowing the drawer 201 to automatically pop out when the dehumidifier bag 202 has absorbed its maximum moisture. This not only facilitates replacement but also serves as a reminder. During the movement of the dehumidifier bag 202, a sensor signal is triggered, such as a contact sensor, which sends a reminder signal to the backend server via the facial recognition smart display screen 102, allowing maintenance personnel to replace the dehumidifier bag 202 promptly.

[0047] In addition, after the maintenance personnel replace the dehumidifying bag 202, they can push the drawer 201 to reset. At this time, the trigger plate 203a returns to its original position under the torque of the first torsion spring 203d. Therefore, the control rope 204c is extended, so that the first pawl 204b contacts the first ratchet 204a under the action of the spring piece. Therefore, the protrusion on the first pawl 204b plays a locking and restraining role on the first ratchet 204a, so that the first ratchet 204a cannot rotate clockwise, thereby ensuring the stability of the drawer 201 when it is closed.

[0048] It should be noted that the high-speed door controller model is SEWEurodrive high-speed door controller. A high-speed door controller is a device used to control the operation of high-speed doors. It typically consists of a main controller and a series of sensors, switches, etc. The high-speed door controller can receive signals from sensors, monitor the door's position, speed, and status, and perform corresponding control operations based on preset parameters.

[0049] Secondly, the dehumidifier bag 202 is filled with a high-molecular-weight moisture-absorbing and expanding material, such as sodium polyacrylate (SAP) and potassium polyacrylate (PAAK), which expand into a gel-like state after absorbing moisture, thus providing a better triggering effect.

[0050] Example 2

[0051] Reference Figure 5-7 This is the second embodiment of the present invention, which differs from the previous embodiment in that it also includes...

[0052] The one-way constraint assembly 300 includes a turntable 301 coaxially fixed to the rotating shaft of the trigger plate 203a. A control rod 302 is hinged to one side of the turntable 301, and a second pawl 303 is hinged to the end of the control rod 302 away from the turntable 301. The second pawl 303 is rotatably connected to the cabinet 101. A second ratchet 304 is provided on one side of the second pawl 303, and the second ratchet 304 is coaxially fixed to the drive gear 203b. A one-way bearing connects the second ratchet 304 and the drive gear 203b. The second pawl 303 is provided with a first position and a second position. When the trigger plate 203a is lifted by the dehumidifying bag 202, the second pawl 303 is in the first position and contacts the second ratchet 304, realizing the one-way rotation of the drive gear 203b; when the trigger plate 203a is not lifted, the second pawl 303 does not contact the second ratchet 304. When the trigger plate 203a is pushed up by the expansion of the dehumidifying bag 202, it drives the turntable 301 to rotate counterclockwise by a preset angle through the rotating shaft. The turntable 301 pushes the second pawl 303 to rotate to the corresponding angle through the hinged control rod 302, so that the second pawl 303 contacts the second ratchet 304 and fixes the drawer 201.

[0053] Because the cabinet door automatically closes after customers collect their tickets, maintenance personnel need to reopen the corresponding cabinet door to replace them, which is time-consuming and labor-intensive.

[0054] To solve the above problems, a one-way constraint component 300 is added to limit the drive gear 203b in one direction. Therefore, the drawer 201 will not move when squeezed by the cabinet door, thus preventing the cabinet door from closing and making it easier for staff to replace the dehumidifying bag 202.

[0055] Specifically, when the trigger plate 203a is pushed up by the expansion of the dehumidifying bag 202, it drives the turntable 301 to rotate counterclockwise by a preset angle through the rotating shaft. The turntable 301 pushes the second pawl 303 to rotate to the corresponding angle through the hinged control rod 302, so that the second pawl 303 contacts the second ratchet 304. When the drawer 201 moves inward, it will drive the drive gear 203b and the second ratchet 304 to rotate clockwise. Therefore, the second ratchet 304 and the second pawl 303 abut against each other, which plays a restraining role on the movement of the drawer 201.

[0056] In other words, by replacing the dehumidifying bag 202, the maintenance personnel restore the trigger plate 203a to its initial angle, which in turn causes the second pawl 303 and the second ratchet 304 to separate, thus restoring the drawer 201 to its original position. It should be noted that when the drawer 201 moves outward, the second ratchet 304, under the action of the one-way bearing, will not rotate coaxially with the drive gear 203b, reducing the problem of mutual interference.

[0057] Example 3

[0058] Reference Figure 2 and Figure 8-9 This is the third embodiment of the present invention, which further provides a smart cabinet for storing tickets using facial recognition. It includes a dust removal component 400 within a cavity to remove moisture. The dust removal component 400 includes a filter frame 401 installed within the cavity. A movable cleaning block 403 is located below the filter frame 401, and both ends of the movable cleaning block 403 are slidably connected to the filter frame 401. A brush layer is fixed to one end of the movable cleaning block 403 facing the filter frame 401. The filter frame 401 and the movable cleaning block 403 are connected by a compression spring. A repulsion block 402 is located at the end of the movable cleaning block 403 away from the compression spring. The repulsion block 402 is slidably connected to the filter frame 401 and is located above a trigger plate 203a. Magnets with opposite magnetic properties are fixed to the opposite surfaces of the repulsion block 402 and the movable cleaning block 403. When the repulsive block 402 is pressed, it will move upward until it corresponds to the movable cleaning block 403. At this time, the movable cleaning block 403 will slide under the action of magnetic repulsion. During the sliding process, the movable cleaning block 403 will drive the brush layer to clean the dust in the filter frame 401, thereby avoiding the accumulation of dust from affecting the dehumidification effect of the dehumidification bag 202.

[0059] When the trigger plate 203a is pushed up by the expansion of the dehumidification bag 202, it will squeeze the repulsion block 402 above. The repulsion block 402 will move upward under pressure until it corresponds with the movable cleaning block 403. At this time, the movable cleaning block 403 will slide under the action of magnetic repulsion. During the sliding process, the movable cleaning block 403 will drive the brush layer to clean the dust in the filter frame 401, thereby avoiding the accumulation of dust from affecting the dehumidification effect of the dehumidification bag 202. During the movement, the movable cleaning block 403 will compress the compression spring to store energy. When the repulsion block 402 resets, the movable cleaning block 403 will automatically return to its original position under the push of the compression spring, achieving a continuous cleaning effect.
