In addition, in the description of the present invention, "multiple" and "several" mean two or more, unless otherwise clearly and specifically defined.

[0025] Reference Figures 1 to 6 A public transportation escalator with a disinfection function comprises a control system and a truss 1, wherein the truss 1 comprises an upper bed 101 and a lower bed 102, wherein the upper bed 101 and the lower bed 102 are provided with a cover plate 2, and wall panels 3 are installed on both sides of the truss 1, and handrail guide rails 4 are installed on the edges of the wall panels 3, and handrail belts 5 are installed on the handrail guide rails 4, and the handrail guide rails 4 include a groove 401 that runs through the whole.

[0026] The upper bed 101 or the lower bed 102 of the truss 1 is provided with a storage container 6, and the storage container 6 is filled with hand sanitizer. The storage container 6 includes two groups of liquid outlets 602 and liquid inlets 601, corresponding to the left and right handrails respectively. Each group of the liquid outlets 602 and liquid inlets 601 is connected to the two ends of the same delivery pipe 7, and a water pump 8 is provided between the liquid outlets 602 and the delivery pipe 7. The delivery pipe 7 is provided with a plurality of (six in this embodiment) atomizing devices 9, and the delivery pipe 7 is placed in the groove 401. The human infrared sensors 10 corresponding to the number of the atomizing devices 9 are installed in the groove 401, and the entire handrail belt 5 is provided with a plurality of holes 501 corresponding to the sensing range of the human infrared sensors 10 and the spray outlet position of the atomizing device 9.

[0027] Specific work flow: When a pedestrian takes the present embodiment, his hand covers the notch 501 and moves with the handrail 5. When the human infrared sensor 10 senses the hand through the notch 501, it sends a signal to the control system. The control system commands the water pump 8 to deliver the hand-free hand disinfectant, and at the same time commands the atomizing device 9 to atomize the hand-free hand disinfectant and spray it onto the hand through the notch 501, so that the palms of the passengers can be disinfected in small amounts and multiple times. The water pump 8 can also be set to operate continuously for a long time, and the response speed of spraying disinfectant water mist will be improved to a certain extent. The hand-free hand disinfectant that has not been atomized flows through the delivery pipe 7 for one cycle, and is then recovered into the storage container 6 through the liquid inlet 601.

[0028] On the other hand, when the flow of people is small and the outside of the handrail 5 needs to be disinfected, the control system can also control the atomization device 9 to spray the hand-free hand disinfectant simultaneously and continuously, and the atomized hand-free hand disinfectant is dispersed on the surface of the handrail 5. As the handrail 5 moves, every part of the handrail 5 is sprayed with the hand-free hand disinfectant, thereby completing the disinfection of the handrail 5.

[0029] This embodiment makes reasonable improvements to the existing escalator structure and has a high degree of intelligence. Without affecting the movement speed of pedestrians, the time when pedestrians take the escalator can be used to disinfect the hands of pedestrians. The handrail 5 can also be disinfected to reduce the occurrence of infection and greatly improve the epidemic prevention effect in crowded places. In addition, the relevant components of the disinfection function of this embodiment are all arranged inside the escalator to maintain the simple external structure of the public transportation escalator to avoid tripping pedestrians.

[0030] It should be noted that the existing handrail guide rail 4 generally has two structures: one is U-shaped, such as Figure 5 As shown, the delivery tube 7 and the human infrared sensor 10 are installed in parallel in the same groove 401; the other is W-shaped, such as Figure 6 As shown, the delivery pipe 7 and the human infrared sensor 10 are installed in the groove 401 on the left and right sides, and this embodiment is an upward escalator and a W-shaped handrail guide rail 4. The wires of the atomizing device 9 and the human infrared sensor 10 (not shown in the drawings) are connected along the groove 401 to the control system inside this embodiment (the upper bed 101 is equipped with a control cabinet, not shown in the drawings).

[0031] In this embodiment, the plurality of atomizing devices 9 and human infrared sensors 10 are only arranged on the oblique and straight sections of the handrail guide rail 4. The reasons are: first, the oblique and straight sections of the handrail guide rail 4 are relatively long, which is convenient for setting the atomizing device 9 and human infrared sensors 10; second, when pedestrians stand on the steps and move to the oblique and straight sections of the handrail guide rail 4, it is generally relatively stable. Under the condition of ensuring safety, pedestrians can let go of the handrail belt 5 and rub their hands to achieve the best effect of the hand-free hand disinfectant; third, to control costs, it is unnecessary and inconvenient to install parts in the arc section and the horizontal and straight section.

[0032] It should be noted that the above hand movements must be performed under safety conditions. It is not recommended for young children to perform such hand movements. Moreover, since the atomizing device 9 is equidistantly arranged throughout the oblique and straight sections, when pedestrians step out of the escalator, there is generally still some wet hand sanitizer on their palms, and they can also rub their hands to achieve the hand disinfection effect. Preferably, the human infrared sensor 10 is fixed with a strip bracket 11 with a U-shaped cross section. The human infrared sensor 10 can be pre-installed on the strip bracket 11 and connected with wires, and then placed in the groove 401, which is easy to install.

[0033] In this embodiment, refer to Figure 3 , each atomizing device 9 and its corresponding human infrared sensor 10 are staggered, and along the movement direction of the handrail 5, the notch 501 first passes through the human infrared sensor 10, and then passes through the atomizing device 9. The staggered setting is due to the fact that there is a reaction time difference in the process from the human infrared sensor 10 sensing the human hand to the atomizing device 9 spraying the hand-free hand disinfectant, and the ladder of this implementation is still moving upward or downward.

[0034] Since the groove 401 of the existing handrail guide rail 4 is narrow in width but deep in depth, the depth of the groove 401 is sufficient to allow the delivery pipe 7 to pass through the bottom of the cover plate 2 in a folded state and be placed in the groove 401. Compared with the delivery pipe 7 surrounding the entire handrail guide rail 4, this structural design greatly reduces the stroke of the hand-free hand disinfectant, and correspondingly: the performance requirements of the water pump 8 are reduced, and the cost of the delivery pipe 7 is also reduced; on the other hand, since the delivery pipe 7 does not need to pass through other parts, it is more convenient to install, and it is also conducive to retrofitting on the installed public transportation type escalator.

[0035] In this embodiment, the pipe section of the delivery pipe 7 where the atomizing device 9 is arranged is made of a hard material, which is convenient for opening holes and installing the atomizing device 9, and the other parts are made of a bendable material, which is convenient for folding in half to be placed in the groove 401 and to bend in accordance with the curvature of the handrail guide rail 4. The bend of the delivery pipe 7 is preferably connected with a U-shaped hollow part to avoid the situation where the fluid cannot pass smoothly.

[0036] In this embodiment, the storage container 6 is provided with a feeding port 603 and an installation and cleaning port 604, and the feeding port 603 is smaller than the installation and cleaning port 604. The installation and cleaning port 604 is used to be large enough for a person to insert a hand, so as to facilitate installation of parts and cleaning of the inner wall. The hand-free hand disinfectant is a volatile solution, so the feeding port 603 is designed to be smaller in size to reduce volatilization, and at the same time, it is convenient to control the size of the feeding pipe 12 described below.

[0037] In this embodiment, in order to prevent the feeding port 603 from being stepped on or the cover 13 from tripping pedestrians, and to facilitate the staff to replenish the hand-free hand disinfectant, the cover plate 2 is provided with a first notch 201 near the handrail 5, the feeding port 603 is connected to one end of the feeding pipe 12, and the other end of the feeding pipe 12 is provided with a cover 13 corresponding to the position of the first notch 201, and the feeding pipe 12 is provided with a fixing ring 14, and the fixing ring 14 is fixed to the truss 1, and the hand-free hand disinfectant can be replenished without removing the cover plate 2. The upper bed 101 of this embodiment needs to be installed with a control cabinet, a speed monitoring device, an armrest 5 drive device and a total drive device, etc., and the lower bed 102 needs to be installed with a tensioning device and an entrance safety device, etc. Therefore, the feeding pipe 12 is provided to extend the feeding port 603 to a position close to the armrest 5.

[0038] In this embodiment, the storage container 6 is provided with an upper sensor 15 for monitoring the water level reaching the upper limit and a green indicator light 17 for prompting the water level reaching the upper limit. When the hand disinfectant added by the staff reaches the upper limit of the water level, the upper sensor 15 sends a signal to the control system, and the control system commands the green indicator light 17 to light up to remind the staff to stop adding the hand disinfectant.

[0039] In this embodiment, the storage container 6 is provided with a lower sensor 16 for monitoring the water level reaching the lower limit and a red indicator light 18 for prompting the water level reaching the lower limit. When the hand-free hand disinfectant is consumed to the lower limit of the water level, the lower sensor 16 sends a signal to the control system, and the control system commands the red indicator light 18 to light up to remind the staff to replenish the hand-free hand disinfectant in time, so as to ensure the normal operation of the disinfection function of this embodiment.

[0040] In this embodiment, a second notch 202 is provided at a position of the cover plate 2 close to the handrail 5, and the light emitting parts of the green warning light 17 and the red warning light 18 are exposed to the surface of the cover plate 2 through the second notch 202. The green warning light 17 and the red warning light 18 are arranged at this position to avoid being stepped on by pedestrians, and the warning lights can be seen more intuitively.

[0041] The present embodiment also includes other devices or components such as steps, step chains, apron plates, step guide rails, etc., which are conventional structural designs in the art and are not the innovation of the present embodiment, and will not be elaborated here.

[0042] The above implementation modes cannot limit the protection scope of the present invention. The equivalent modifications and changes made by those skilled in the art without departing from the overall concept of the present invention are still within the scope of the present invention.
