[0003] Currently, some equipment for cleaning and sterilizing handrails has appeared on the market. However, the development of such equipment is still in its early stages. Most escalator handrail cleaning still relies on manual methods, such as wiping the handrails with cloths and detergents. This is time-consuming and labor-intensive, and it is difficult to guarantee the continuity of cleaning effect and the thoroughness of disinfection. This situation cannot meet the requirements of public places for hygiene and cleaning efficiency and standards. In order to address the existing shortcomings, an escalator handrail disinfection and cleaning device is proposed. Utility Model Content

[0031] like Figure 1-4 As shown, this utility model provides an escalator handrail disinfection and cleaning device, including a housing 10. The housing 10 is equipped with a disinfection mechanism 20, a cleaning mechanism 30 and a control mechanism 5050. The disinfection mechanism 20 includes a water storage tank 21, a water injection pipe 23, a water pump 24 and a spray head 26. The water injection pipe 23 is located at the upper end of the water storage tank 21 and passes through the housing 10. The water pump 24 is located on one side above the water storage tank 21. The spray head 26 is located on the other side above the water storage tank 21 and is embedded in the front side of the housing 10.

[0032] The cleaning mechanism 30 is located below the disinfection mechanism 20. The cleaning mechanism 30 includes a stepper motor 31, a guide block 32, a lead screw 33, a push rod 35, and a roller brush 39. The lead screw 33 passes through the guide block 32, and one end of it is connected to the output end of the stepper motor 31. The push rod 35 is located above the lead screw 33, and the roller brush 39 is located at the front end of the push rod 35.

[0033] The control mechanism 50 is located behind the disinfection mechanism 20 and the cleaning mechanism 30. The control mechanism 50 includes a power board 51, a controller 52, a control panel 53 and a rechargeable battery 54. The control panel 53 is screwed to the rear side of the housing 10. The power board 51, the controller 52 and the rechargeable battery 54 are installed inside the housing 10.

[0034] Furthermore, in this embodiment, the water injection pipe 23 is connected to the water storage tank 21, and the water injection pipe 23 facilitates the replenishment of the cleaning liquid in the water storage tank 21. The water pump 24 is connected to the spray head 26 and the water storage tank 21 by water delivery pipes 25, which facilitate the water pump 24 to draw the cleaning liquid from the water storage tank 21 and transmit it to the spray head 26 for spraying. A liquid level sensor 22 is installed on one side of the water storage tank 21. The liquid level sensor 22 is installed inside the water storage tank 21 to monitor the content of the cleaning liquid in the water storage tank 21.

[0035] In this embodiment, the output end of the stepper motor 31 is connected to the lead screw 33. The lead screw 33 is threadedly engaged with the guide block 32. A connecting seat 34 is provided between the guide block 32 and the push rod 35. The connecting seat 34 is screwed to the guide block 32 and the push rod 35. The push rod 35 is movably connected to the outer shell 10. The stepper motor 31 controls the lead screw 33 to rotate inside the outer shell 10. Based on the action of the thread, the guide block 32 is horizontally displaced on the outer surface of the lead screw 33, which causes the push rod 35, which is connected to the guide block 32 through the connecting seat 34, to move synchronously. The push rod 35 drives the front end roller brush 39 to move synchronously.

[0036] In this embodiment, rollers 311 are fixed at both ends of the roller brush 39. The two rollers 311 are respectively engaged with quick-release clips A 38 and B 37. A hinge 310 is screwed between quick-release clips A 38 and B 37. The hinge 310 connects quick-release clips A 38 and B, and the hinge 310 is a spring hinge, so that quick-release clip B 37 can be tightly pressed against the surface of rollers 311 by the spring force to clamp the roller brush 39. The inner sides of quick-release clips A 38 and B 37 are fixed with locking blocks. The surfaces of the two rollers 311 are provided with locking holes that are adapted to the locking blocks. The roller brush 39 with rollers 311 is locked inside quick-release clips A 38 and B by the cooperation of the locking blocks and locking holes.

[0037] In this embodiment, a baffle plate 36 is fixed to the front end of the push rod 35. The baffle plate 36 is connected to the quick-release buckle 38 by screws. The shape of the baffle plate 36 is adapted to the roller brush 39. The baffle plate 36 prevents the cleaning liquid sprayed by the disinfection mechanism 20 above from splashing into the inside of the outer shell 10.

[0038] In this embodiment, a sewage recovery tank 40 is screwed to one side of the bottom of the outer casing 10. The sewage recovery tank 40 is located directly below the roller brush 39, and the sewage cleaned by the sewage recovery tank 40 is collected.

[0039] In this embodiment, the control screen 53 is a touch screen display. The output terminals of the control screen 53 and the liquid level sensor 22 are communicatively connected to the input terminal of the controller 52. The output terminal of the controller 52 is communicatively connected to the input terminal of the power board 51. The output terminal of the power board 51 is electrically connected to the input terminals of the water pump 24 and the stepper motor 31. The control screen 53 sends control signals to the controller 52. The controller 52 receives monitoring data from the liquid level sensor 22. The controller 52 controls the switch of the power board 51, and the power board 51 provides power.

[0040] Specifically, when the water pump 24 is started, water is pumped through the water pipe 25, so that the cleaning liquid in the water storage tank 21 is sucked in through the water pipe 25 and transmitted to the spray head 26 for spraying. The liquid level sensor 22 is installed in the water storage tank 21 to monitor the liquid level in real time and transmit the signal to the controller 52.

[0041] Among them, the liquid level sensor 22 can be an ultrasonic liquid level sensor installed on the top of the water storage tank, vertically downwards towards the water surface. This installation method can avoid the influence of liquid flow or obstacles inside the tank on the measurement. Alternatively, a radar liquid level sensor can be installed on the top of the water storage tank, perpendicular to the liquid surface. This sensor measures the liquid level by emitting radio waves, is suitable for high-precision measurement and is not affected by obstacles inside the tank. Or, a hydrostatic liquid level sensor can be installed at the bottom of the water storage tank, calculating the liquid level height by measuring the liquid pressure.

[0042] The roller brush 39 is connected to quick-release clips A 38 and B 37 via roller 311. Quick-release clips A 38 and B 37 work together to hold the roller brush 39 in place. When the roller brush 39 needs to be replaced or maintained, the quick-release clip B 37 is manually opened while the quick-release clip A 38 remains stationary. The roller 311 with the roller brush 39 is then inserted, and the quick-release clip B 37 is then fastened, thus completing the quick installation of the roller brush 39. In addition, a spare roller brush storage box 11 is provided at the bottom of the outer casing 10 to store multiple spare roller brushes 39, making it convenient for maintenance personnel to replace and maintain the roller brush 39, thereby improving the maintenance efficiency of the equipment.

[0043] The wastewater recycling tank 40 is installed on the bottom front side of the outer casing 10 by a snap-fit ​​method, which makes it easy to remove and empty wastewater and perform daily cleaning;

[0044] The stepper motor 31 starts under the command of the controller 52, driving the lead screw 33 to rotate. The rotation of the lead screw 33 is converted into the linear reciprocating motion of the guide block 32, which drives the push rod 35, which is connected to the guide block 32 through the connecting seat 34, to move synchronously. The baffle plate 36 at the front end of the push rod 35 drives the roller brush 39 to gradually approach the escalator handrail, and finally achieves close contact with the handrail. Thus, the roller brush 39 is passively rotated and cleaned by the movement of the handrail.

[0045] The electronic components are powered by the rechargeable battery 54. The controller 52 is the control center of the control mechanism 5050. It is responsible for coordinating the work of the power board 51, control panel 53, water pump 24, liquid level sensor 22 and stepper motor 31. The power board 51 integrates a charging interface and a power switch. When the power switch is turned on, the controller 52 displays the operation interface on the control panel 53 for the operator to control.

[0046] Cleaning Principle: The device is placed at the lower end of the inclined end of the escalator handrail. The controller 52 first reads the data from the liquid level sensor 22 to detect the remaining liquid in the water tank 21. If the liquid in the water tank 21 is insufficient, the operator needs to unscrew the cap at the outer end of the water injection pipe 23 and add disinfectant to the water tank 21 through the water injection pipe 23. After the cleaning liquid volume reaches the threshold, the water pump 24 is started. The water pump 24 controls the movement of the cleaning liquid and sprays the cleaning liquid from the spray head 26 onto the surface of the escalator handrail for cleaning and disinfection. Then, the stepper motor 31 drives the screw 33 to advance through the control panel 53, controlling the roller brush 39 to gradually approach the escalator handrail until it reaches the appropriate cleaning position. When the handrail is running, the roller brush 39 contacts the surface of the handrail and rolls with the handrail. The roller brush 39 rotates synchronously on the card block through the roller 311. The roller brush 39 cleans the surface of the handrail, brushing off water stains and impurities, which fall into the sewage recycling tank 40.

[0047] In addition, during equipment operation, operators can cut off the power supply at any time using the power switch on the power board 51 to ensure operational safety.

[0048] It is worth noting that the control method in this application is controlled by controller 52. The electronic components are connected by power lines. The control circuit of controller 52 can be implemented by simple programming by those skilled in the art. It is common knowledge in the art, and this application will not explain the control method and circuit connection in detail.
