[0057] In recent years, many studies have shown that plasma-activated water is a highly efficient, mild, and environmentally friendly disinfectant and sterilizing substance, and it is now widely used in disinfection, food preservation, and instrument cleaning.

[0058] This invention is a device that uses the principle of plasma-activated water disinfection and sterilization to disinfect escalators. It can simultaneously disinfect and clean the escalator handrails, and complete the work automatically and continuously, improving sterilization and cleaning efficiency, saving manpower, and achieving better disinfection and sterilization results.

[0059] Plasma is a gaseous substance composed of positive and negative ions generated after atoms and atomic groups are ionized. Macroscopically, it is electrically neutral and represents the fourth state of matter in nature, in addition to solids, liquids, and gases. Plasma is classified into high-temperature plasma and low-temperature plasma based on its temperature. Low-temperature plasma can generate large amounts of reactive oxygen species (ROS) and reactive nitrogen species (RNS) with bactericidal and disinfecting properties at near-ambient temperatures. Directly treating water with low-temperature plasma generates a large amount of active substances at the gas-liquid interface, which diffuse into the water and react to produce an aqueous solution with even more active components—this is plasma-activated water. Numerous studies have demonstrated that plasma-activated water is a novel disinfectant with excellent fluidity and permeability, and it has been widely applied in areas such as fruit and vegetable preservation and equipment cleaning.

[0060] In view of this, see Figure 1-8 This application provides a plasma-activated liquid automatic escalator disinfection device, which includes a housing, a clamping assembly, a plasma-activated liquid generating device, a disinfection assembly, and a pipeline assembly.

[0061] See Figure 1-3The housing 100 defines the internal space, and the housing 100 is provided with a slot 110 that communicates with the internal space. The handrail 20 of the escalator can pass through the slot 110 and be embedded in the internal space. Specifically, the housing 100 can be located below the upper end or below the lower end of the escalator, so that the plasma activation liquid escalator disinfection device 10 will not occupy too much space when in use, thus not affecting the use of the escalator. In this application, the housing 100 is located below the lower end of the escalator as an example for explanation.

[0062] The clamping assembly 200 is located in the internal space and can detachably clamp the side panel of the escalator embedded in the internal space. Specifically, the clamping assembly 200 may include two suction cups that can move closer or further apart. After the escalator is inserted into the slot 110, the two suction cups can move closer together to clamp the side panel of the escalator, thereby realizing the installation and fixation of the plasma activation liquid escalator disinfection device 10.

[0063] A plasma activation liquid generator 600 is located in the internal space and is used to generate plasma activation liquid.

[0064] The disinfection assembly 300 includes a first roller body 310 and a first side roller 330 and a second side roller 340 disposed on both sides of the first roller body 310. The first roller body 310 is used to abut against the wall surface of the handrail belt 20 away from the side panel, and the first side roller 330 and the second side roller 340 are used to abut against the two opposite side walls of the handrail belt 20. The first roller body 310, the first side roller 330 and the second side roller 340 can all generate rolling friction with the handrail belt 20. The parts of the three rollers that abut against the handrail belt 20 can all be made of sponge, silicone, cotton sleeve or other absorbent materials, and are used to wipe the plasma activation liquid onto the handrail belt 20, thereby disinfecting the handrail belt 20.

[0065] One end of the pipe assembly 500 is connected to the plasma activation liquid generator 600 for obtaining the plasma activation liquid, and the other end faces the disinfection assembly 300 for guiding the plasma activation liquid to the first roller 310, the first side roller 330, and the second side roller 340. The port of the pipe assembly 500 near the three rollers can be positioned above the three rollers to drip the plasma activation liquid onto them. The pipe assembly 500 can be a plastic hose or a metal hose, and the position of the outlet can be manually adjusted.

[0066] The pipe assembly 500 is arranged at an angle and configured to guide the plasma activation liquid to the first roller 310, the first side roller 330 and the second side roller 340 by gravity.

[0067] In this application, disinfection using a plasma activation solution is cleaner and more environmentally friendly than chemical disinfection methods, leaving no chemical residue. Furthermore, the plasma activation solution has strong disinfection capabilities and high efficiency, requiring almost no manual maintenance during the disinfection process, thus saving on operating costs. Moreover, in this application, the plasma activation solution is guided by gravity to the first roller 310, the first side roller 330, and the second side roller 340, eliminating the need for electricity in the plasma activation solution's output process, thereby further reducing the cost of using the plasma activation solution.

[0068] See Figure 3 as well as Figure 8 In some embodiments, the disinfection assembly 300 further includes a second roller 320 and a third side roller 350 and a fourth side roller 360 disposed on both sides of the second roller 320. The second roller 320 abuts against the wall surface of the handrail belt 20 away from the side plate, and the third side roller 350 and the fourth side roller 360 abut against the two opposite side walls of the handrail belt 20. The second roller 320 is disposed obliquely above the first roller 310, the third side roller 350 is disposed obliquely above the first side roller 330, and the fourth side roller 360 is disposed obliquely above the second side roller 340. Specifically, the plasma activated liquid escalator disinfection device 10 can be engaged with the upward handrail belt 20 or the downward handrail belt 20. For ease of description, this application will use the example of the plasma activated liquid escalator disinfection device 10 being engaged with the upward handrail belt 20 for illustration. In this solution, the handrail belt 20 is first wiped and disinfected by the first roller 310, the first side roller 330, and the second side roller 340, and then cleaned by the second roller 320, the third side roller 350, and the fourth side roller 360. This solution can effectively remove residual plasma.

[0069] In some embodiments, the end of the conduit assembly 500 facing the first roller 310, the first side roller 330, and the second side roller 340 is configured to be driven to face the second roller 320, the third side roller 350, and the fourth side roller 360, so that the conduit assembly 500 can guide the plasma activation liquid to the second roller 320, the third side roller 350, and the fourth side roller 360. In this embodiment, considering that the plasma activation liquid escalator disinfection device 10 may get stuck on the descending handrail belt 20, in which case the second roller 320 needs to disinfect and the first roller 310 needs to clean, the position of the conduit assembly 500 can be manually adjusted so that the plasma activation liquid is guided to the second roller 320, the third side roller 350, and the fourth side roller 360.

[0070] See Figure 3 as well as Figure 8In some embodiments, the disinfection assembly 300 includes a first support plate 370 and a second support plate 380, which are arranged parallel to each other. Both the first support plate 370 and the second support plate 380 are V-shaped, and the first support plate 370 includes a first end and a second end, while the second support plate 380 includes a third end and a fourth end. A first roller body 310 is connected to the first end at one end and the third end at the other end; a second roller body 320 is connected to the second end at one end and the fourth end at the other end; a first side roller 330 is connected to the first end at one end; a second side roller 340 is connected to the third end at one end; a third side roller 350 is connected to the second end at one end; and a fourth side roller 360 is connected to the fourth end at one end. The disinfection assembly 300 also includes a connecting shaft 390, which is connected to the middle of the first support plate 370 at one end and the middle of the second support plate 380 at the other end. The housing 100 includes a first wall plate 120 and a second wall plate 130 located on both sides of the bayonet 110. The first wall plate 120 has a first strip groove 121, and the second wall plate 130 has a second strip groove 131. One end of the connecting shaft 390 is slidably connected to the first strip groove 121, and the other end of the connecting shaft 390 is slidably connected to the second strip groove 131. The connecting shaft 390 can slide along the length direction of the first strip groove 121 and the second strip groove 131 to a working position where both the first roller 310 and the second roller 320 abut against the handrail belt 20, and can also slide along the length direction of the first strip groove 121 and the second strip groove 131 to a separation position where both the first roller 310 and the second roller 320 are separated from the handrail belt 20. In this design, the disinfection component 300 can be easily installed and fixed to adapt to handrail belts 20 of different shapes and sizes.

[0071] See Figure 3 as well as Figure 5-8In some embodiments, a first slider 122 is provided in the first strip groove 121. The first slider 122 is rotatably connected to the connecting shaft 390. The first slider 122 is provided with a first locking rod 123, and the end of the first locking rod 123 opposite to the first slider 122 is provided with a first locking groove. A second slider is provided in the second strip groove 131. The second slider is rotatably connected to the connecting shaft 390. The second slider is provided with a second locking rod, and the end of the second locking rod opposite to the second slider is provided with a second locking groove. The first wall panel 120 is provided with a first locking block. A first rotating block 124 is provided in the first locking block. The first rotating block 124 and the first locking block are rotatably connected by a torsion spring. The first rotating block 124 is provided with an opening, and a first engaging protrusion 125 is provided in the opening of the first rotating block 124. The first locking rod 123 can be inserted into the first rotating block 124, and the first engaging protrusion 125 engages with the first locking groove. The second wall panel 130 is provided with a second locking block, within which is a second rotating block. The second rotating block and the second locking block are rotatably connected by a torsion spring. The second rotating block has an opening, and within the opening is a second engaging protrusion. A second locking rod can be inserted into the second rotating block, and the second engaging protrusion engages with a second locking groove. In this design, when the connecting shaft 390 slides to the working position, it can be locked by the first rotating block 124 and the second rotating block. Furthermore, the first rotating block 124 can unlock the first locking rod 123 by rotating, and the second rotating block can unlock the second locking rod by rotating, making the locking and unlocking of the disinfection component 300 very convenient.

[0072] In some embodiments, the housing 100 further includes a back plate 140 facing away from the bayonet 110. The back plate 140 has a closed state with its internal space closed and an open state with its internal space open. In the open state of the back plate 140, the connecting shaft 390 can be rotated to a position where the first roller 310 and the second roller 320 face the back plate 140 after moving to the separated position. In this design, when the disinfection assembly 300 needs maintenance or replacement, the connecting shaft 390 can be slid to the separated position and then rotated to rotate the first roller 310 and the second roller 320 to a position facing the back plate 140, thus facilitating maintenance and replacement of the first roller 310 and the second roller 320 after the operator opens the back plate 140.

[0073] See Figure 3-4 In some embodiments, the plasma activation solution generating device 600 includes a plasma generator 610 and a water tank 620. The water tank 620 is used to hold the activation solution. The plasma generator 610 is located above the water tank 620. The water tank 620 has a liquid guiding hole 621, and the pipe assembly 500 communicates with the liquid guiding hole 621. In subsequent use, only the activation solution needs to be added; the activation solution can specifically be water.

[0074] In some embodiments, there are multiple plasma generators 610, arranged in a rectangular array above the water tank 620. The plasma activation liquid generating device 600 also includes a fan 630, which is positioned above each plasma generator 610 to guide the generated plasma into the activation liquid. The fan 630 helps guide the plasma into the water tank 620.

[0075] See Figure 3 , Figure 4 as well as Figure 8 In some embodiments, the plasma activation liquid generator 600 further includes a button 710 assembly. The button 710 assembly includes a button 710 disposed outside the housing 100, a transmission assembly 720, and a baffle 730 disposed within the water tank 620. One end of the transmission assembly 720 is connected to the button 710, and the other end is connected to the baffle 730. The button 710 can drive the transmission assembly 720, causing the transmission assembly 720 to drive the baffle 730 upward to the open position of the liquid guide hole 621 or downward to the position of blocking the liquid guide hole 621. During operation, the liquid guide hole 621 can be opened and closed by driving the button 710 up and down. When the liquid guide hole 621 is open, water in the water tank 620 can be guided to the pipe assembly 500. When the liquid guide hole 621 is closed, water in the water tank 620 cannot be guided to the pipe assembly 500.

[0076] In some embodiments, the plasma-activated liquid escalator disinfection device 10 further includes a power generation component 400 disposed in the internal space. The power generation component 400 includes a power generation roller 410, which is configured to abut against the handrail belt 20 and rotate under the drive of the handrail belt 20 for generating electricity. The power generation component 400 is electrically connected to the plasma-activated liquid generator 600 to supply power to the plasma-activated liquid generator 600.

[0077] See Figure 3 Figure 7 as well as Figure 8In some embodiments, the plasma-activated liquid escalator disinfection device 10 further includes a power generation component 400 disposed in the internal space. The power generation component 400 includes a power generation roller 410, which is connected to the rotating shaft of the first roller body 310. The power generation roller 410 is configured to be driven by the first roller body 310 to generate electricity. The power generation component 400 is electrically connected to the plasma-activated liquid generator 600 to supply power to the plasma-activated liquid generator 600. In this scheme, the power generated by the movement of the handrail belt 20 is fully utilized to generate electricity, thereby using the generated electricity to power the plasma-activated liquid generator 600. This allows the plasma-activated liquid escalator disinfection device 10 of this application to completely eliminate the need for an additional power supply, further reducing the operating cost. In other embodiments, the power generation roller 410 may also be connected to the second roller body 320 or other roller bodies, which will not be elaborated here.

[0078] In some embodiments, the housing 100 is further provided with four support legs, which together support the housing 100. The height of each of the four support legs is adjustable, thereby facilitating the positioning of the housing 100.

[0079] In some embodiments, see Figure 4 The plasma generator 610 includes a rod-shaped electrode 611 and a ring-shaped electrode 612. The rod-shaped electrode 611 extends into the ring-shaped electrode 612. The rod-shaped electrode 611 is connected to the positive electrode, and the ring-shaped electrode 612 is connected to the negative electrode.
