A replenishment tube 210 is connected to one side of the top of the disinfectant container 32. The replenishment tube 210 is made of PP plastic, with a diameter of 20mm and a length of 30mm. A cap 211, made of ABS material, is threaded onto its top and has an internal silicone sealing ring. The sealing surface pressure is ≥0.3MPa, effectively sealing the replenishment port and preventing disinfectant evaporation or the entry of external impurities. A maintenance plate 37, made of stainless steel with a thickness of 2mm and a bolt spacing of 30mm, is fixedly connected to the bottom of the disinfectant container 32 by four M4 cross-slot bolts. This facilitates disassembly and maintenance of internal components such as the guide plate 33 and the suction pump 35, reducing maintenance costs.

[0033] In some specific embodiments, the guide plate 33 can be made of stainless steel with a thickness of 2mm. It adopts an inclined design with an inclination angle of 15°, and the pipe is connected to the low-lying area of ​​the guide plate 33. This guides the disinfectant solution to converge towards the pipe, preventing disinfectant solution residue in the box, with a residue amount ≤5mL. The guide plate 33 is fixed to the bottom of the inner cavity of the disinfectant solution box 32 by welding. The weld is uniform and continuous, without any incomplete or missing welds, ensuring structural stability.

[0034] In some specific embodiments, the liquid level sensor 34 can be a capacitive liquid level sensor with a measurement range of 0-500mL, a measurement accuracy of ±1%FS, and an output signal of 4-20mA analog signal, capable of real-time monitoring of the remaining disinfectant level in the disinfectant container 32. The sensor is installed 10mm from the top of the guide plate 33 and is fixed to the disinfectant container 32 via a threaded interface. A PTFE sealing gasket is provided at the interface to ensure sealing performance and prevent disinfectant leakage from affecting the sensor's operation. When the remaining disinfectant level is below 50mL, the sensor will send a signal to the control module to remind the staff to replenish the disinfectant in time.

[0035] In some specific embodiments, the suction pump 35 can be a miniature gear pump with a rated voltage of 24V DC, a rated flow rate of 1L / min, a working pressure of 0.3MPa, a power of 15W, and a compact size (40mm long × 30mm wide × 25mm high) to fit the installation space at the bottom of the disinfectant container 32. The suction pump 35 is connected to the pipe at the bottom of the guide plate 33 via a silicone tube with an inner diameter of 8mm and a wall thickness of 2mm, exhibiting strong corrosion resistance and adaptability to various disinfectants. The outlet of the suction pump 35 is connected to an atomizing nozzle 36 via a silicone tube of the same specification to ensure smooth disinfectant delivery.

[0036] In some specific embodiments, the atomizing nozzle 36 can be a high-pressure atomizing nozzle, with a conical spray pattern, a spray angle of 60°, and a droplet size of 10-50μm, capable of evenly atomizing and spraying the disinfectant onto the operating area of ​​the call box.

The atomizing nozzle 36 is made of 304 stainless steel, which resists corrosion from the disinfectant and extends its service life.

[0037] Specifically: the lead screw 25 is set along the length of the moving groove 23, and the suction pump 35 is fixed to the bottom of the disinfectant box 32. After the user presses the button, the suction pump 35 works to deliver the disinfectant in the inner cavity of the disinfectant box 32 to the inner cavity of the atomizing nozzle 36. The disinfectant can be sprayed out through the atomizing nozzle 36 to disinfect the user's hands.

[0038] The end of the lead screw 25 away from the dual output shaft motor 24 is fixedly connected to the inner wall of the moving groove 23 through a bearing to ensure the stability of the lead screw 25 during rotation and reduce shaking and wear.

[0039] The inner cavity of the movable block 26 is provided with a threaded hole for use with the lead screw 25. The threads of the upper and lower lead screws 25 are designed in opposite directions. The reverse thread design can drive the upper and lower movable blocks 26 to move in opposite directions synchronously, so that the protective cover 27 can open and close smoothly and improve operating efficiency.

[0040] The protective cover 27 has a groove 29 on the side near the limiting block 28 for use with the connecting post 31. The groove 29 can avoid the connecting post 31, ensuring that the protective cover 27 can fit tightly against the summoning box body when closed, without affecting the protective effect and the normal operation of the disinfection component 3.

[0041] The top of the disinfectant container 32 is connected to a replenishment tube 210. The top of the replenishment tube 210 is threaded with a cap 211. The replenishment tube 210 provides a convenient channel for replenishing the disinfectant, and the cap 211 can seal the replenishment port to prevent the disinfectant from evaporating or external impurities from entering, thus ensuring the disinfection effect.

[0042] The guide plate 33 is designed with an inclination, and the pipe is connected to the low-lying part of the guide plate 33. The inclination design of the guide plate 33 can guide the disinfectant to converge in the direction of the pipe, avoid the disinfectant residue in the box, and ensure that the suction pump 35 can fully draw the disinfectant.

[0043] The bottom of the disinfectant container 32 is fixedly connected to a maintenance plate 37 by bolts. The maintenance plate 37 is fixed by bolts, which facilitates disassembly and maintenance of components such as the guide plate 33 and the suction pump 35 inside the disinfectant container 32, thereby reducing maintenance costs.

[0044] The top and bottom ends of the back of the smart summoning box body 1 are fixedly connected to the mounting plates 4. The mounting plates 4 have mounting holes on both sides. The mounting plates 4 and the mounting holes provide a stable mounting structure for the summoning box body, making it easy to install quickly on the wall of the elevator floor and adapt to different installation scenarios.

[0045] In some specific embodiments, the mounting plate 4 can be made of Q235 cold-rolled steel plate with a thickness of 3mm. It has mounting holes on both sides with a diameter of 8mm and a center distance of 60mm. It is compatible with M6 or M8 expansion bolts, which can quickly fix the call box body 1 to different materials such as concrete or brick walls on the elevator landing wall. The mounting plate 4 and the body 1 are fixed by four M4 hexagon socket head cap bolts with a bolt spacing of 50mm to ensure a firm connection.

[0046] An NFC card reader 5 is fixedly connected to the surface of the smart summoning box body 1. Users can quickly trigger the opening of the protective component 2 through an NFC card to prevent other users from opening and closing the protective component 2 at will and causing damage.

[0047] In some specific embodiments, the NFC reader 5 can be a 13.56MHz high-frequency reader with a reading distance of 0-5cm, a response time of ≤100ms, and support for the ISO14443A / B protocol. It is compatible with mainstream NFC cards and mobile phone NFC functions on the market. After the user identifies themselves via NFC, the protective component 2 can be triggered to operate, effectively preventing unauthorized personnel from opening and closing the protective cover 27 and causing damage, thus improving the safety of the device.

[0048] The inner wall of the protective cover 27 is bonded with protective cotton by adhesive, and rubber pads are bonded to the opposite sides of the upper and lower protective covers 27 by adhesive. The protective cotton enhances the buffer protection capability of the protective cover 27, and the rubber pads can reduce the impact wear when the protective cover 27 is closed, while improving the sealing effect and further optimizing the protective performance.

[0049] The smart call box of this application is fixed to a predetermined position on the wall of the elevator landing using M6 expansion bolts through the mounting holes on the mounting plate 4. The fit between the mounting surface and the wall is ≤0.5mm, ensuring a firm installation. In use, the user can bring an NFC card close to the NFC reader 5 on the surface of the smart call box body 1, or use the NFC function of their mobile phone for identification. After receiving a valid signal, the NFC reader 5 sends a command to the control module, triggering the operation of the protective component 2. At this time, the dual-output shaft motor 24 starts, driving the reverse lead screws 25 at both ends to rotate synchronously. The moving block 26, threaded onto the lead screw 25, slides smoothly along the moving groove 23 at a speed controlled at 5mm / s. Simultaneously, the limiting block 28 slides synchronously within the limiting groove 22, driving the upper and lower protective covers 27 to separate by a distance of 180mm, exposing the call box operating area for user use. The entire opening and closing process takes ≤36 seconds, with smooth and seamless operation. After the user completes the call operation, the control module sends a closing command after a 5-second delay. The dual-output shaft motor 24 rotates in reverse, driving the protective cover 27 to close, thus protecting the operating area. Simultaneously, the disinfection component 3 starts working, and the suction pump 35 activates, drawing out the disinfectant collected in the disinfectant tank 32 via the guide plate 33. This disinfectant is then atomized by the atomizing nozzle 36 and evenly sprayed onto the call box operating area, disinfecting the button surfaces and surrounding areas that the user has touched. The disinfection lasts for 10 seconds to ensure effectiveness. The liquid level sensor 34 monitors the remaining disinfectant level in the disinfectant tank 32 in real time. When the level falls below a set threshold, a replenishment reminder signal is sent to the property management platform via the elevator control system. Upon receiving the reminder, staff can open the cap 211 on the replenishment tube 210 to add disinfectant to the disinfectant tank 32. After replenishment, the cap 211 is tightened to ensure a seal. When the disinfection component 3 malfunctions and needs repair, the staff can unscrew the bolts on the inspection plate 37 at the bottom of the disinfectant container 32, remove the inspection plate 37, and inspect and repair the internal components such as the guide plate 33, the suction pump 35, and the pipes. After the repair is completed, the inspection plate 37 is reinstalled to ensure that the connection is firm and the seal is good.

[0050] This application achieves effective protection of the operating area of ​​the smart summoning box body 1 through the protective component 2, resisting the impact of external forces and environmental factors, and extending the service life of the equipment; and achieves rapid disinfection after use through the disinfection component 3, which solves the hygiene problems caused by the large number of users in traditional summoning boxes, and is especially suitable for densely populated places such as hospitals, office buildings, and shopping malls, improving the safety and comfort of users.
