[0029] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0030] Figures 1-5 show an escalator with a disinfection device according to this embodiment. The escalator includes a main body. The main body is a conventional device of the prior art, including a truss and a handrail belt 1 that moves on the truss. The disinfection device 2 is installed at two rotating ends of the handrail belt 1 to cooperate with the handrail belt 1. The disinfection device 2 includes a housing 3 and a floating component. The housing 3 is fixed to the side of the handrail belt 1. The housing 3 has a first liquid storage chamber 31, a liquid delivery tank 33, and a liquid collection tank 34 formed on it. The first liquid storage chamber 31, the liquid delivery tank 33, and the liquid collection tank 34 are all arranged with open tops and are used to store disinfectant. The liquid delivery tank 33 is arranged to the side of the first liquid storage chamber 31. A first connecting port 35 communicating with the first liquid storage chamber 31 is machined on the side wall of the liquid delivery tank 33. When disinfectant is added to the first liquid storage chamber 31, the disinfectant can enter the liquid delivery tank 33 through the first connecting port 35.

[0031] In this embodiment, the highest liquid level of the first liquid storage chamber 31 is higher than the highest liquid level of the liquid delivery tank 33. By reasonably designing the position of the first connecting port 35, the disinfectant in the first liquid storage chamber 31 can flow into the liquid delivery tank 33.

[0032] The aforementioned disinfection roller 4 is positioned above the liquid delivery tank 33, with its central axis mounted on a bracket via bearings, allowing it to rotate around its central axis. The central axis of the disinfection roller 4 extends along the length or width of the liquid delivery tank 33. The edge of the disinfection roller 4 extends into the liquid delivery tank 33 through its opening. When the disinfectant reaches a preset level in the liquid delivery tank 33, the edge of the disinfection roller 4 comes into contact with the disinfectant. A ring of sponge layer 41 is arranged on the surface of the disinfection roller 4. When the disinfection roller 4 rotates, the sponge layer 41 absorbs the disinfectant from the liquid delivery tank 33. The sponge layer 41 contacts the handrail belt 1, allowing the absorbed disinfectant to be applied to the handrail belt 1.

[0033] The aforementioned floating element is arranged within the liquid delivery tank 33. This floating element floats according to the liquid level within the tank 33, having an upward position and a downward position away from the upward position. When the floating element is in the upward position, it closes the first connecting port 35 to prevent the disinfectant in the first storage chamber 31 from entering the liquid delivery tank 33. When the floating element is in the downward position, it opens the first connecting port 35 to allow the disinfectant in the first storage chamber 31 to enter the liquid delivery tank 33.

[0034] The aforementioned wiping roller 6 is a conventional component of the prior art, with a cloth or rubber surface. The wiping roller 6 is positioned above the collection tank 34, and its central axis is mounted on a bracket via bearings, allowing it to rotate around its own central axis. The central axis of the wiping roller 6 extends along the length or width of the collection tank 34. The edge of the wiping roller 6 extends into the collection tank 34. The wiping roller 6 contacts the handrail belt 1 to wipe the handrail belt 1, and the disinfectant carried by the wiping roller 6 is collected into the collection tank 34.

[0035] In this embodiment, of the two sets of disinfection devices 2 at the rotating end of the handrail belt 1, the first disinfection roller 4 contacts the handrail belt 1, and the second wiping roller 6 has its wheel surface in contact with the handrail belt 1. Through the above structural design, the disinfection roller 4 coats the handrail belt 1 with disinfectant, while the wiping roller 6 wipes the disinfectant off the handrail belt 1.

[0036] The aforementioned disinfection rollers 4 and wiping rollers 6 are arranged side-by-side with a predetermined distance between them. Two sets of the aforementioned escalator main bodies are arranged side-by-side. These two sets of escalator main bodies form two adjacent and parallel sets of handrail belts 1. The sponge layer 41 on the disinfection rollers 4 of each set of disinfection devices 2 contacts and engages with one set of handrail belts 1, and the wheel surface of the wiping rollers 6 of each set of disinfection devices 2 contacts and engages with the other set of handrail belts 1. This structural design enables simultaneous disinfection of both sets of handrail belts 1, saving installation costs and improving installation efficiency.

[0037] In this embodiment, the aforementioned floating component includes a float plate 5 and a switch plate 52 connected to the float plate 5. The float plate 5 is designed to have buoyancy so that it can float within the liquid delivery tank 33. The switch plate 52 is vertically movably arranged within the liquid delivery tank 33 or the first liquid storage cavity 31, and is in contact with the side wall on the side where the first connecting port 35 is located. In this embodiment, the switch plate 52 is arranged within the first liquid storage cavity 31. A vertically extending guide groove is arranged on the side wall of the first liquid storage cavity 31. The switch plate 52 is slidably installed in the guide groove so that it can move up and down. The switch plate 52 and the float plate 5 are connected by a connector inserted through the first connecting port 35. With the above structural design, when the floating component is in the upward position, the switch plate 52 closes the first connecting port 35. And when the floating component is in the aforementioned downward position, the switch plate 52 opens the first connecting port 35. In a specific structural design, the float plate 5 is provided with a clearance opening 51 for the disinfection roller 4 to pass through, so as to prevent the float plate 5 from interfering with the rotation of the disinfection roller 4.

[0038] In this embodiment, a scraper 7 is fixedly installed inside the aforementioned collection tank 34. The scraper 7 is in contact with the wheel surface of the wiping wheel 6. The scraper 7 scrapes the disinfectant off the wheel surface of the wiping wheel 6, allowing the disinfectant to be collected in the collection tank 34, while also facilitating subsequent wiping operations of the wiping wheel 6.

[0039] A second liquid storage chamber 32 is arranged beside the liquid collection tank 34 on the box body 3. A second communication port 36, connecting to the liquid collection tank 34, is machined on the side wall of the second liquid storage chamber 32. By rationally designing the position of the second communication port 36, the disinfectant in the liquid collection tank 34 can be transferred and transported to the second liquid storage chamber 32, thus achieving stable operation of the disinfection wiping operation. Specifically, a partition plate is installed inside the box body 3. This partition plate is plugged into the box body 3 and can be disassembled. The aforementioned first liquid storage chamber 31 and second liquid storage chamber 32 are located on opposite sides of the partition plate. An observation window, connecting the first liquid storage chamber 31 and the second liquid storage chamber 32, is machined on the side wall of the box body 3. A transparent plate 8 is sealed and covered over the observation window. The liquid level inside the first liquid storage chamber 31 and the second liquid storage chamber 32 can be observed through the transparent plate 8.

[0040] In this embodiment, an end cap 9 is arranged on the box body 3. The end cap 9 seals the opening of the first liquid storage chamber 31 and the opening of the second liquid storage chamber 32.

[0041] In practical use, disinfectant is added to the first storage chamber 31, and then enters the delivery tank 33 through the first connecting port 35. As the level of disinfectant in the delivery tank 33 rises, it causes the float 5 to rise to the floating position, so that the switch plate 52 closes the first connecting port 35. The disinfection device 2 is arranged at the two rotating ends of the handrail belt 1. The sponge layer 41 on the disinfection roller 4 of one set of disinfection devices 2 contacts the handrail belt 1, and the wiping roller 6 of the other set of disinfection devices 2 contacts the handrail belt 1. The disinfection roller 4 rotates with the movement of the handrail belt 1, so that the sponge layer 41 on the disinfection roller 4 can absorb the disinfectant in the delivery tank 33 and coat it onto the surface of the handrail belt 1. When the level of disinfectant in the delivery tank 33 drops, the float 5 drops synchronously to the lowered position, so that the switch plate 52 opens the first connecting port 35, thereby automatically replenishing the disinfectant in the first storage chamber 31 into the delivery tank 33, so that the level of disinfectant in the delivery tank 33 rises. The wiping wheel 6 rotates as the handrail belt 1 moves, wiping away excess disinfectant from its surface and collecting it in the collection tank 34 before returning it to the second storage chamber 32. This method allows for real-time disinfection and wiping of the escalator's handrail belt 1, ensuring it is thoroughly disinfected and dry, and enabling automatic replenishment of the disinfectant, effectively meeting the escalator's operational needs.

[0042] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
