Description

Technical Field

[0001] This invention belongs to the field of disinfection device technology, and more specifically, relates to an intelligent sensing spray disinfection system for precise contact positioning of escalators and its usage method. Background Technology

[0002] Escalators are fixed, electrically driven devices with circulating steps used to transport passengers upwards or downwards along an incline. Widely used in public places, escalators typically have synchronized handrails on the upper surface of their glass partitions to ensure passenger comfort. However, bacteria accumulate on these handrails over time, potentially causing cross-infection among passengers. Given the stringent hygiene requirements for public facilities, cleaning currently relies on manual wiping with cleaning tools. The large number of escalators and the large handrail area make manual methods inefficient and time-consuming. Therefore, developing a device capable of thoroughly cleaning and disinfecting handrails is of great significance.

[0003] To address the aforementioned problems, Chinese invention patent CN112010146A discloses an escalator disinfection device, comprising a base, a cleaning component, and a drive wheel. The cleaning component includes two first disinfection rotating wheels and one second disinfection rotating wheel, both having an impregnation layer. The first disinfection rotating wheels are rotatably mounted on the base via a first rotating shaft. The two first disinfection rotating wheels are located on opposite sides of the handrail, with the impregnation layer of each first disinfection rotating wheel adhering closely to the side and top surface of the handrail. The second disinfection rotating wheel is rotatably mounted on the base, facing the handrail, with its impregnation layer adhering closely to the outer surface of the bottom side of the handrail. The drive wheel is mounted on the base, adhering closely to the outer surface, and rotatably positioned between the two first disinfection rotating wheels. This escalator disinfection device achieves efficient and comprehensive cleaning and disinfection of the handrail, saving manpower, reducing cleaning and disinfection costs, and requiring no additional external force during operation, thus being energy-saving and environmentally friendly.

[0004] Furthermore, Chinese invention patent CN113428767A discloses an escalator disinfection system, including a disinfectant storage tank and a wastewater tank. The disinfectant storage tank, located within a base steel frame below the escalator cover, is cuboid in shape, with two piston rods on its upper surface. A pedal is fixed above the piston rods, and a disinfection mechanism passes through the handrail near one end of the escalator step. The wastewater tank is positioned along the escalator direction on one side of the disinfectant storage tank. This device is simple to modify for escalators, occupies little space, and can effectively clean and disinfect the escalator handrail, providing continuous disinfection.

[0005] The above-mentioned patented technical solutions all effectively achieve the disinfection and cleaning of escalator handrails by using mechanical equipment, but the following problems still exist: (1) Existing escalator disinfection devices have complex structures and installations, are expensive, and have high operating costs; (2) For devices that use cleaning wheels, since the cleaning wheels need to maintain continuous contact with the handrail, long-term operation inevitably causes damage to the cleaning wheels themselves or a reduction in cleaning performance, and no easily replaceable mechanical structure is provided, resulting in inconvenience in equipment maintenance; (3) Since the amount of disinfectant fed is constant, when the ambient temperature is low, the disinfectant on the surface of the handrail is difficult to evaporate completely, causing the disinfectant on the handrail to stick to the passenger's palm, thus causing hygiene and safety problems. Summary of the Invention

[0006] To address the aforementioned deficiencies or improvement needs of existing technologies, this invention provides an intelligent sensing spray disinfection system for precise contact positioning of escalators and its usage method. By incorporating a removable disinfection ring within the disinfection unit, the ring rotates in the same direction as the roller shaft during handrail movement. This causes the disinfection ring, which absorbs disinfectant, to rotate and position itself at the contact point of the handrail, thus automatically disinfecting the handrail surface by the disinfectant dripping onto it.

[0007] To achieve the above objectives, according to one aspect of the present invention, a precise contact positioning intelligent sensing spray disinfection system for escalators is provided, comprising:

[0008] A disinfectant delivery unit fixed to the outside of a glass railing for providing disinfectant solution includes a disinfectant container for holding the disinfectant solution and a delivery hose for conveying the disinfectant solution.

[0009] A disinfection unit for contacting and disinfecting the surface of a handrail includes a removable roller with a central pivot and a removable disinfection ring fitted onto the surface of the roller.

[0010] The flexible needle connected to the disinfection ring and the conveying tube, and the connecting rod rotatably connected to the roller shaft;

[0011] And a position adjustment unit for maintaining good contact between the disinfection unit and the handrail, comprising an inclined support rod with one end fixedly connected to the connecting rod and having a telescopic function, and a vertical support rod with a telescopic function for adjusting the support angle of the inclined support rod. The top of the vertical support rod is slidably connected to the middle section of the inclined support rod. The inclined support rod and the vertical support rod are respectively provided with an inclined support rod positioning knob and a vertical support rod positioning knob, so as to realize the position adjustment of the disinfection unit until the disinfection soft ring is in direct contact with the handrail. The disinfection liquid in the disinfection liquid container flows through the delivery tube to the flexible tube needle, and finally flows into the surface of the disinfection soft ring and is absorbed by it and rotates to the contact point of the handrail to achieve disinfection.

[0012] Furthermore, the disinfectant delivery unit includes a flow control valve for controlling the output flow rate of the disinfectant, which is connected in series in the middle section of the delivery pipe.

[0013] Furthermore, the disinfectant delivery unit includes a hose connector fixing plate for assisting in positioning the hose needle and the delivery tube, with its lower half fixedly connected to the side of the hose needle and its upper half fixedly connected to the side of the delivery tube.

[0014] Furthermore, the disinfection unit includes a semi-circular protective cover disposed on the outer surface of the disinfection soft ring and serving a protective function.

[0015] Furthermore, the disinfection unit includes a descaling section for squeezing out residual disinfectant from the disinfection ring, which is fixedly connected to the lower end of the protective cover.

[0016] Furthermore, the shape of the dehydration section is an angular body protruding towards the central axis of rotation.

[0017] Furthermore, the disinfection unit includes a waste liquid container for collecting residual disinfectant solution squeezed out, the waste liquid container being placed directly below the descaling section.

[0018] Furthermore, the lower ends of the inclined support rod and the vertical support rod are respectively rotatably connected to a first base and a second base fixed to the ground.

[0019] According to a second aspect of the present invention, a method for disinfecting escalator handrails is provided, implemented using the aforementioned escalator precise contact positioning intelligent sensing spray disinfection system, comprising:

[0020] S100: The disinfectant delivery unit is fixedly installed on the outside of the glass railing, the position adjustment unit is installed on the ground, and the disinfection unit is installed on the upper end of the inclined support rod;

[0021] S200: The inclined support rod and the vertical support rod are stretched to adjust the position of the upper end of the inclined support rod, thereby adjusting the position of the disinfection unit until the disinfection soft ring in the disinfection unit is in direct contact with the handrail;

[0022] S300: By rotating the diagonal support rod positioning knob and the vertical support rod positioning knob, the diagonal support rod and the vertical support rod are positioned, thereby keeping the relative position of the disinfection unit and the handrail fixed.

[0023] S400: The disinfectant in the disinfectant container flows through the delivery tube to the flexible needle, and finally flows into the surface of the disinfectant coil and is absorbed by it;

[0024] S500: When the handrail moves, it drives the sterilized soft ring in the same direction with the roller shaft as the central axis.

[0025] The rotation causes the disinfectant ring, which absorbs the disinfectant solution, to rotate and reach the contact point of the handrail, thereby allowing the disinfectant solution to fall onto the surface of the handrail for disinfection.

[0026] In summary, compared with the prior art, the above-described technical solutions conceived by this invention can achieve the following beneficial effects:

[0027] 1. The system of the present invention, by setting an easily detachable disinfection soft ring in the disinfection unit, when the handrail moves, drives the disinfection soft ring to rotate in the same direction with the roller shaft as the central shaft, so that the disinfection soft ring part that absorbs disinfectant rotates to the contact point of the handrail, thereby realizing the automatic disinfection of the disinfectant falling onto the surface of the handrail.

[0028] 2. The system of this invention uses a flow control valve to control the output of disinfectant, providing different supply amounts according to different environments. This not only effectively reduces disinfectant waste but also effectively solves the hygiene and safety problem caused by disinfectant sticking to passengers' palms when the ambient temperature is low, as the disinfectant on the handrail surface is difficult to evaporate completely. During use, since the flow control valve is exposed, it is advisable to manually control the flow control valve until no disinfectant drips below the disinfection ring.

[0029] 3. The system of the present invention controls the working intensity of the drying device by detecting the humidity value by a humidity sensor, and can also control the flow control valve to increase or decrease the flow of disinfectant accordingly, thereby further solving the hygiene and safety problem caused by disinfectant sticking to passengers' palms when the disinfectant on the handrail surface is difficult to evaporate completely.

[0030] 4. The system of the present invention can be easily disassembled and replaced if the cleaning wheel itself is damaged or its cleaning performance is reduced, thereby improving the convenience and safety of the equipment.

[0031] 5. The method of the present invention involves stretching the inclined support rod and the vertical support rod to adjust the position of the upper end of the inclined support rod, thereby adjusting the position of the disinfection unit until the disinfection ring in the disinfection unit is in direct contact with the handrail. By rotating the positioning knobs of the inclined support rod and the vertical support rod, the inclined support rod and the vertical support rod are positioned, thereby fixing the relative position of the disinfection unit and the handrail. The disinfectant in the disinfectant container flows through the delivery tube to the flexible tube needle and into the disinfection ring. When the handrail moves, it drives the disinfection ring to rotate in the same direction around the roller shaft as the central shaft, so that the disinfection ring part that has absorbed the disinfectant rotates to the contact point of the handrail, thereby achieving disinfection by the disinfectant falling onto the surface of the handrail.

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0037] like Figures 1-2 As shown, this embodiment of the invention provides an intelligent sensing spray disinfection system for precise contact positioning of escalators, comprising:

[0038] The disinfectant delivery unit 3, which is used to provide disinfectant to the disinfection device, is fixed to the outside of the glass railing 2. The disinfectant delivery unit 3 includes a disinfectant container 301 for holding disinfectant and a delivery tube 303 for conveying disinfectant. One end of the delivery tube 303 is connected to the outlet of the disinfectant container 301.

[0039] The disinfection unit 4, which is used for disinfection in direct contact with the surface of the handrail 1, includes a roller 401 with a roller shaft 402 as the central shaft and which is easily detachable, a disinfection soft ring 403 sleeved on the surface of the roller 401 and which is easily detachable, a semi-circular protective cover 404 located on the outer surface of the disinfection soft ring 403 and which plays a protective role, and a flexible tube needle 304 passing through a through hole opened at the upper end of the protective cover 404. The flexible tube needle 304 is connected to the conveyor belt 303, and the roller shaft 402 is rotatably connected to the connecting rod 407.

[0040] The position adjustment unit 5, used to ensure good contact between the disinfection unit 4 and the handrail 1, includes an inclined support rod 511 with one end fixedly connected to the connecting rod 407 and having a telescopic function, and a vertical support rod 521 with a telescopic function for adjusting the support angle of the inclined support rod 511. The lower ends of the inclined support rod 511 and the vertical support rod 521 are respectively rotatably connected to a first base 513 and a second base 523 fixed to the ground. The inclined support rod 511 and the vertical support rod 521 are respectively provided with an inclined support rod positioning knob 512 and a vertical support rod positioning knob 522 for fixing the length. The upper end of the vertical support rod 521 is slidably connected to the middle section of the inclined support rod 511.

[0041] In this embodiment of the invention, by setting a removable disinfection soft ring 403 in the disinfection unit 4, if the cleaning wheel itself is damaged or its cleaning performance is reduced when the escalator is running for a long time, it can be easily disassembled and replaced, thereby improving the convenience and safety of the equipment. The device has a simple structure. By setting a structure that allows the handrail to drive the disinfection device to rotate, the disinfection device rotates as a driven component, which simplifies the design difficulty of the transmission system. Compared with the existing escalator disinfection devices, the cost is greatly reduced, and the installation difficulty is also reduced.

[0042] During installation, the disinfectant delivery unit 3 is fixedly installed on the outside of the glass railing 2, the position adjustment unit 5 is installed on the ground, and the disinfection unit 4 is installed on the upper end of the inclined support rod 511.

[0043] In use, firstly, stretch the inclined support rod 511 and the vertical support rod 522 to adjust the position of the upper end of the inclined support rod 511, thereby adjusting the position of the disinfection unit 4 until the disinfection soft ring 403 in the disinfection unit 4 is in direct contact with the handrail 1. Next, rotate the inclined support rod positioning knob 512 and the vertical support rod positioning knob 522 to position the inclined support rod 511 and the vertical support rod 522, thereby fixing the relative position of the disinfection unit 4 and the handrail 1. Next, the disinfectant in the disinfectant container 301 flows through the delivery tube 303 to the flexible tube needle 304, and finally flows into the surface of the disinfection soft ring 403 and is absorbed by it. Then, when the handrail 1 moves, it drives the disinfection soft ring 403 to rotate in the same direction around the roller shaft 402 as the central shaft, so that the part of the disinfection soft ring 403 that has absorbed the disinfectant rotates to the contact point of the handrail 1, thereby allowing the disinfectant to fall onto the surface of the handrail 1, ultimately achieving the disinfection effect.

[0044] like Figures 1-2 In this embodiment of the invention, the disinfectant delivery unit 3 includes:

[0045] A flow control valve 302 is used to control the output flow rate of disinfectant solution, and it is connected in series in the middle section of the conveying pipe 303.

[0046] In this embodiment of the invention, a flow control valve is used to control the output of disinfectant, providing different supply amounts according to different environments. This not only effectively reduces the waste of disinfectant but also effectively solves the problem that when the ambient temperature is low, the disinfectant on the handrail surface is difficult to evaporate completely, leading to...

[0047] Hand sanitizer residue on passengers' palms poses a hygiene and safety concern. When using this product, since the flow control valve is exposed, it is advisable to manually adjust the flow control valve until no sanitizer drips below the sanitizing ring.

[0048] like Figure 2 In this embodiment of the invention, the disinfectant delivery unit 3 includes:

[0049] The hose connector fixing plate 305 used for assisting in positioning the hose needle 304 and the conveyor belt 303 has its lower half fixedly connected to the side of the hose needle 304 and its upper half fixedly connected to the side of the conveyor belt 303.

[0050] like Figures 1-2 In this embodiment of the invention, the disinfection unit 4 includes:

[0051] The disinfection soft ring 403 is made of cotton material that easily absorbs the solution.

[0052] like Figures 1-2In this embodiment of the invention, the disinfection unit 4 includes:

[0053] The desiccant section 405, used to squeeze out residual disinfectant from the disinfection soft ring 403, is fixedly connected to the lower end of the protective cover 404. The desiccant section 405 is shaped as an angular body protruding towards the central axis of rotation.

[0054] Waste liquid container 406 is used to collect residual disinfectant after extrusion, and the waste liquid container 406 is placed directly below the descaling section 405.

[0055] like Figures 1-2 As shown, in this embodiment of the invention, the position adjustment unit 5 includes:

[0056] The first base 513 and the second base 523 are fixedly connected to the ground by self-tapping screws.

[0057] like Figure 1 As shown in the embodiment of the present invention, the intelligent sensing spray disinfection system for precise contact positioning of escalators includes:

[0058] A drying device 6 for drying the disinfectant on the surface of the handrail 1 is fixedly installed facing the surface of the handrail 1; a humidity sensor 601 for detecting the humidity of the surface of the handrail 1.

[0059] In this embodiment of the invention, the humidity value detected by the humidity sensor 601 is used to control the working intensity of the drying device 6. At the same time, the flow control valve 302 can be controlled to increase or decrease the flow rate of the disinfectant, thereby further solving the hygiene and safety problem caused by the disinfectant sticking to the palms of passengers when the disinfectant on the surface of the handrail is difficult to evaporate completely.

[0060] This invention provides a method for using an intelligent sensing spray disinfection system for precise contact positioning on escalators, comprising the following steps:

[0061] S100: The disinfectant delivery unit 3 is fixedly installed on the outside of the glass railing 2, the position adjustment unit 5 is installed on the ground, and the disinfection unit 4 is installed on the upper end of the inclined support rod 511.

[0062] S200: The inclined support rod 511 and the vertical support rod 522 are stretched to adjust the position of the upper end of the inclined support rod 511, thereby adjusting the position of the disinfection unit 4 until the disinfection soft ring 403 in the disinfection unit 4 is in direct contact with the handrail 1.

[0063] S300: At this time, by rotating the oblique support rod positioning knob 512 and the vertical support rod positioning knob 522, the oblique support rod 511 and the vertical support rod 522 are positioned, so that the relative position of the disinfection unit 4 and the handrail 1 remains fixed.

[0064] S400: The disinfectant in the disinfectant container 301 flows through the delivery tube 303 to the flexible needle 304, and finally flows into the surface of the disinfection soft ring 403 and is absorbed by it.

[0065] S500: When the handrail 1 moves, it drives the disinfection soft ring 403 to rotate in the same direction with the roller shaft 402 as the central shaft. This causes the part of the disinfection soft ring 403 that has absorbed the disinfectant to rotate to the contact point of the handrail 1, so that the disinfectant falls onto the surface of the handrail 1, and finally achieves the disinfection effect.

[0066] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention.
