Description

Technical Field

[0001] The present invention relates to the technical field of disinfection and sterilization of transportation systems, and in particular to a disinfection device and a disinfection method. Background Art

[0002] Transportation systems, such as luggage security equipment, food production lines, and escalators, often use circularly moving belt or chain structures such as conveyor belts or conveyor chains to achieve transportation purposes. They are widely used in various public places such as subways, airports, shopping malls, hospitals, and factories.

[0003] Since the transportation system itself comes into contact with many transported objects, it is very easy to be contaminated with various bacteria or viruses. Once the transportation system is set up in an environment with a large flow of people and poor air quality, it is easy to cause the spread of diseases. There are many types of sterilizers currently available. One is to spray cleaning liquid and clean it with a brush, etc. This method requires frequent addition of cleaning liquid and does not clean thoroughly. Another is to irradiate with ultraviolet light and generate power through friction between the transportation equipment and the cleaning equipment. This method often uses mercury lamps, which has a certain risk of pollution. It only simply rotates to generate electricity and does not work if it does not rotate. It does not have an intelligent power supply and control system, which can easily cause the transportation equipment to fail to complete sterilization when it is at low speed or stopped. It also does not have audio and video indication functions and cannot purify the air around the transportation equipment. Summary of the Invention

[0063] 1.

By coordinating the different working states of the first disinfection unit with the different working states of the second disinfection unit, the working mode of the entire disinfection device is switched, so that the disinfection device can be applied to a variety of different working scenarios and perform corresponding disinfection work according to different working scenarios;

[0066] 4. The present invention draws the outside air near the transport system into the box body through the air inlet fan and passes it through the photocatalyst filter. The UVA-LED irradiates the photocatalyst filter to sterilize and filter the air drawn by the air inlet fan, and then discharges it through the air outlet fan, thereby facilitating the sterilization and purification of the air near the transport system.

[0067] 5. The present invention arranges a frame and the first, second and third areas within the frame, and arranges the first disinfection unit within the first area, the second disinfection unit within the second area, and the control unit within the third area, so that the structure within the frame is more compact, thereby making the disinfection device of the present invention smaller in size and requiring less space during operation.

DETAILED DESCRIPTION

[0079] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0080] In the description of the embodiments of the present invention, it should be noted that, unless otherwise specified or limited, the term "connected" should be understood in a broad sense. For example, it can mean a fixed connection, a detachable connection, or an integral connection. It can be a mechanical connection, an electrical connection, a direct connection, or an indirect connection through an intermediate medium. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0081] The terms "top," "bottom," "above," "below," and "on" used throughout the description refer to relative positions of components of a device, such as the relative positions of top and bottom substrates within a device. It will be understood that devices are multifunctional regardless of their orientation in space.

[0082] The disinfection device of the embodiments of the present invention is primarily intended for disinfecting circulating components of transportation systems, including but not limited to luggage security equipment, food processing lines, express delivery equipment, and escalators. Corresponding circulating components include conveyor belts in luggage security equipment, conveyor belts in food processing lines, conveyor chains in express delivery equipment, and handrails in escalators. When the disinfection device of the embodiments of the present invention is applied to a transportation system, the disinfection device can be directly or indirectly detachably fixed to the transportation equipment, or it can be built into the transportation equipment.

[0083] like Figure 1 As shown, optionally, the embodiment of the present invention is applied to the disinfection of an escalator handrail, and the disinfection device of the embodiment of the present invention is directly installed on the handrail bracket of the escalator for disinfection.

[0084] In an embodiment of the present invention, the disinfection device includes:

[0085] The first disinfection unit 7 includes an ultraviolet light source, which mainly uses ultraviolet light emitted by the ultraviolet light source to perform ultraviolet sterilization on the circulating moving parts of the transportation system;

[0086] The second disinfection unit 4 includes an air flow channel 403, which includes an inlet 401 and an outlet 405. A disinfection device is provided in the air flow channel 403. Air near the transportation system enters the air flow channel 403 through the inlet 401. The inflowing air is disinfected by the disinfection device, and the disinfected air flows out of the air flow channel 403 through the outlet 405.

[0087] The control unit 11 is used to switch the working mode of the disinfection device between the first mode and the second mode. In the first mode, one of the first disinfection unit 7 and the second disinfection unit 4 is working. In the second mode, the first disinfection unit 7 and the second disinfection unit 4 are working simultaneously. The control unit 11 switches the first mode and the second mode according to the operating state of the transportation system, and ensures the working efficiency of the first disinfection unit 7 and the second disinfection unit 4 by selecting different modes for different operating states of the transportation system. The control unit 11 judges the operating state of the transportation system based on, but is not limited to: 1. The motion state of the circulating motion component is different, such as high-speed operation, low-speed operation, and stopped operation of the circulating motion component; 2. The working environment of the transportation system is different, such as whether there are people passing by; 3. The transportation volume of the transportation system is different, such as the number of items transported by the transportation system per unit time. The control unit 11 can use a single-chip microcomputer or a programmable logic device (FPGA).

[0088] The power supply is electrically connected to the first disinfection unit 7 and the second disinfection unit 4 ; the power supply is used to supply power to the first disinfection unit 7 and the second disinfection unit 4 , and also to supply power to the control unit 11 .

[0089] Optionally, in an embodiment of the present invention, the first mode is activated when the transport system moves within a first speed range; the second mode is activated when the transport system moves within a second speed range; and the speed value within the first speed range is less than the speed value within the second speed range. That is, the control unit 11 switches the working mode of the disinfection device between the first mode and the second mode according to the different movement speeds of the circulating motion parts. The transport system includes at least two motion states, namely a high-speed motion state and a low-speed motion state: when the transport system is in a high-speed motion state, the second mode is used for disinfection, and both the first disinfection unit 7 and the second disinfection unit 4 are working to ensure the disinfection effect; when the transport system is in a low-speed motion state, the first mode is used for disinfection, and the first disinfection unit 7 or the second disinfection unit 4 is working to reduce power consumption.

[0090] When the embodiment of the present invention is used to disinfect the handrail of an escalator, the speed of the handrail in a normal state is greater than the speed of the escalator in an idle state when no one is using it, that is, when the speed of the handrail is low, no one passes by the escalator, and the need for air disinfection is reduced. When the disinfection device of the embodiment of the present invention is in the first mode, the control unit 11 controls the first disinfection unit 7 to work. At this time, since the escalator is traveling at a low speed and the electric energy it provides is also limited, in this state, it is only used to directly irradiate the handrail with ultraviolet light for disinfection. As time accumulates, the disinfection of the handrail not only reduces the toxic substances in the handrail, but also reduces the toxic substances in the handrail. Therefore, the handrail can be in a good sanitary state when someone rides it next time. When people ride the escalator, since the escalator is operating normally and the speed is higher than the idle state, ultraviolet disinfection and air disinfection are performed simultaneously, which can improve the disinfection efficiency of the escalator, so that the handrail can be in a good sanitary state.

[0091] In an embodiment of the present invention, a disinfection device includes: a frame 1 having a first side wall, a second side wall, and a third side wall connected in sequence. A first region, a second region, and a third region are arranged parallel between the first and third side walls; a first disinfection unit 7 is arranged in the first region, a second disinfection unit 4 is arranged in the second region, and a control unit 11 is arranged in the third region; the third region is at least partially bounded by the first, second, and third side walls; the first and second regions are at least partially bounded by the first and second side walls; the first and second regions at least partially share a common boundary; and the first and third regions at least partially share a common boundary. The frame 1 of the embodiment of the present invention adopts a semi-enclosed structure. The open portion facilitates the first disinfection unit 7 in the first region to emit ultraviolet light to disinfect the circulating moving parts of the transport system. The second region is open at least at the inlet 401 and outlet 405 where air flows in. The third region is set as an open or closed area according to actual use requirements.

[0092] The first disinfection unit 7 of the embodiment of the present invention uses ultraviolet disinfection to disinfect the circulating moving parts of the transportation system. Specifically, the first disinfection unit 7 further includes a shortwave ultraviolet generator that emits shortwave ultraviolet light (UVC) onto the circulating moving parts of the transportation system; the shortwave ultraviolet generator is disposed within the first area. The UVC light irradiates the circulating moving parts of the transportation system for ultraviolet disinfection. For example, the UVC light irradiates the handrails of an escalator to disinfect the escalator.

[0093] like Figure 2As shown, the short-wave ultraviolet generator uses a UVC-LED (ultraviolet C-Light Emitting Diode UVC-LED short-wave ultraviolet light-emitting diode) chip. Compared with a mercury lamp, it has low energy consumption, small size, safety and environmental protection. In this embodiment of the present invention, the control unit 11 controls the operation and stop of the short-wave ultraviolet generator.

[0094] The first disinfection unit 7 uses ultraviolet light to directly irradiate the surface of the object for disinfection. Since LED light sources generally have low energy consumption, the disinfection operation can be completed even when electricity is not very abundant. It is suitable for disinfecting the surface of the object.

[0095] The second disinfection unit 4 of the embodiment of the present invention is used to disinfect the air, and may adopt, but is not limited to, one or more of the following technical means: activated carbon adsorption, photocatalysis, molecular sieve filtration, ozone oxidation, plasma purification, high-temperature disinfection, etc. Disinfection of the air requires the provision of power for air circulation and requires a disinfection method that fully contacts the air. Therefore, generally speaking, it has higher energy consumption than the case of using only ultraviolet light source for disinfection. Especially when using self-generated electricity or battery power, it is necessary to select the start or stop of the second disinfection unit 4 according to different working environments.

[0096] When using the embodiment of the present invention, the control unit 11 controls the working mode of the embodiment of the present invention according to different working states of the transportation system. For example:

[0097] When the transportation equipment is an escalator, the escalator has at least two working states: normal operation and idling operation: when the escalator is in normal operation, that is, there are passengers using the escalator, the handrail moves at a fast speed, and there is also a need for air purification around the escalator. The control system controls the first disinfection unit 7 and the second disinfection unit 4 to work simultaneously, performing efficient ultraviolet disinfection on the handrail and air disinfection on the air around the escalator, so that passengers can be in a clean environment; when the escalator is in idling operation, that is, no passengers are using the escalator, the handrail moves at a low speed, and the need for air purification around the escalator is not great. The control system controls the first disinfection unit 7 to work inefficiently and the second disinfection unit 4 not to work, and only performs inefficient ultraviolet disinfection on the handrail. Due to the low possibility of contamination, the inefficient cumulative disinfection of the first disinfection unit 7 can have a better disinfection effect, which is also beneficial to reducing energy consumption. The need for air purification is not great, and the energy consumption of the second disinfection unit 4 is significantly greater than that of the first disinfection unit 7. Therefore, stopping the second disinfection unit 4 can save energy.

[0098] When the transportation equipment is a machining assembly line, the machining assembly line has at least two working states: unmanned operation and manned operation: when the machining assembly line is in a manned operation state, that is, the machining assembly line is operated or monitored by personnel, and the demand for environmental purification is relatively high. The control system controls the first disinfection unit 7 and the second disinfection unit 4 to work simultaneously, and performs efficient ultraviolet disinfection on the conveyor belt and air disinfection on the air around the machining assembly line, so that the staff are in a clean environment; when the machining assembly line is in an unmanned working state, the demand for environmental purification is relatively low. The control system controls the first disinfection unit 7 to work inefficiently, and the second disinfection unit 4 does not work, and only performs inefficient ultraviolet disinfection on the conveyor belt. The inefficient cumulative disinfection of the first disinfection unit 7 can have a better disinfection effect, which is also beneficial to reducing energy consumption. The demand for air purification is not large, and the energy consumption of the second disinfection unit 4 is significantly greater than that of the first disinfection unit 7. Therefore, stopping the second disinfection unit 4 can save energy.

[0099] Preferably, in an embodiment of the present invention, the second disinfection unit 4 adopts photocatalytic catalysis, that is, by irradiating the photocatalyst catalyst with light, the photocatalyst catalyst undergoes photocatalytic catalysis, producing a strong oxidizing substance, thereby achieving purification. Specifically, the second disinfection unit 4 also includes: a fan, which rotates to generate a suction force to provide power for air to flow from the inlet 401 to the outlet 405 in the air flow channel 403; a photocatalyst carrier, which is arranged in the air flow channel 403 and is provided with a photocatalyst catalyst; a long-wave ultraviolet light source 402, the light emitted by the long-wave ultraviolet light source 402 is directed to the photocatalyst catalyst on the photocatalyst carrier. When the second disinfection unit 4 is working, the fan runs, so that the air to be purified enters the air flow channel 403 through the inlet 401 of the air flow channel 403, and the long-wave ultraviolet light source 402 emits long-wave ultraviolet light (ultraviolet A, UVA) to irradiate the photocatalyst catalyst on the photocatalyst carrier. The photocatalyst catalyst purifies the air by catalyzing the air flowing through the photocatalyst carrier.

[0100] like Figure 3 、 Figure 4As shown, the internal structure of the second disinfection unit 4 is provided, and the air flow channel 403 is a straight pipe arranged in the second area, which shortens the total stroke of the air flow channel 403 and reduces the weakening of the suction force of the fan by the air flow. The inlet 401 of the air flow channel 403 is arranged on the first side wall, and the outlet 405 is arranged on the third side wall. The air flow channel 403 can pass through the disinfection device of the embodiment of the present invention. The distance between the inlet 401 and the outlet 405 is relatively large. The air discharged from the outlet 405 is difficult to be directly re-inhaled by the inlet 401. The side wall of the air flow channel 403 serves as the boundary between the second area and the first area at least in part. The inlet 401 and the outlet 405 of the air flow channel 403 are both provided with fans, which are the air intake fan at the inlet 401 and the air outlet fan at the outlet 405. Long-wave ultraviolet light source 402 is a UVA-LED chip. Its long-wave ultraviolet light triggers a photocatalytic reaction in a photocatalyst on a photocatalyst carrier, purifying the air. The photocatalyst carrier is a photocatalyst filter 404, which is positioned transversely within air flow channel 403. All air flowing within air flow channel 403 passes through photocatalyst filter 404. Long-wave ultraviolet light source 402 emits long-wave ultraviolet light toward the photocatalyst carrier.

[0101] like Figure 5 As shown, a specific structure of the second area of ​​an embodiment of the present invention is provided. When the transportation system is an escalator: the second area is in the form of a square tube, and fan installation cavities are provided at the inlet 401 and the outlet 402 of the air flow channel 403. The fan installation cavity at the inlet 401 is installed with an intake fan, and the fan installation cavity at the outlet 405 is installed with an outlet fan. A long-wave ultraviolet light source 402 is provided on the downstream side wall of the fan installation cavity at the inlet 401, and a photocatalyst filter 404 is provided on the upstream side wall of the fan installation cavity at the outlet 405. The side wall of the air flow channel 403 is the common boundary between the first area and the second area.

[0102] like Figure 2 、 Figure 3As shown, the disinfection device of an embodiment of the present invention uses self-generation to provide power. Specifically, the power supply generates electricity through a generator, which is powered by the transportation system. That is, the power supply includes a generator, which is arranged in the first area; the generator includes a power input and a power output, and the power input is used to connect to the transportation system. Exemplary methods of power connection include but are not limited to: when the circulating moving component of the transportation system is a belt-like structure, the circulating moving component drives the power input of the generator to rotate through friction; when the circulating component of the transportation system is a chain-like structure, the circulating moving component drives the power input of the generator to rotate through a sprocket. In addition, the circulating moving component of the transportation system can also be connected to the power supply using an external structure, for example, through an external wheel axle, gear set, transmission belt, etc. to achieve power transmission and realize generator power generation. The disinfection device of the embodiment of the present invention uses self-generation to provide power, without modifying the transportation system. It only needs to be equipped with a structure in the power supply of the embodiment of the present invention that can drive the circulating moving component of the transportation system to achieve the disinfection function. At the same time, the self-generation device is compatible with the switching of working modes, adapting to the matching between energy supply and different disinfection requirements in different working scenarios.

[0103] Preferably, in an embodiment of the present invention, the power input end includes: a rotor 6, which is used for friction transmission with the circulating motion components of the transportation system, and the rotation of the rotor 6 realizes the generation of electricity by the generator. The axis of the rotor 6, the axis of the ultraviolet light source, and the axis of the air flow channel 403 are parallel, making the interior of the disinfection device of the embodiment of the present invention more compact. For example, in an embodiment of the present invention, the transportation system is an escalator, and the circulating motion component is the handrail of the escalator, which at least partially enters the first area and frictionally transmits the rotation with the rotor 6. When the escalator is operating normally, the handrail and the rotor 6 frictionally transmit the rotation to realize the generation of electricity by the generator, which supplies power to the first disinfection unit 7, the second disinfection unit 4, and the control unit 11 of the embodiment of the present invention. When the escalator is in normal operation, the handrail drives the generator to generate electricity. The movement speed of the handrail is relatively high, and the output power of the generator is also relatively high. The electricity generated is sufficient to supply power to the first disinfection unit 7, the second disinfection unit 4, and the control unit 11. In addition, the generator is arranged in the first area, and the rotor 6 and the handrail belt adopt friction transmission. When the rotor 6 adopts a roller type structure, the volume of the rotor 6 itself is small, and the rotor 6 and the handrail belt are in line contact, so that the embodiment of the present invention does not need to cover a large area of ​​the handrail belt to achieve self-generation.

[0104] In an embodiment of the present invention, a belt-type escalator handrail comprises a first sidewall and a third sidewall provided with a fixed plate 2 that is fixedly connected or integrally formed.

For example, the fixed plate 2 is provided with a threaded hole 3, through which a screw is inserted to connect to the handrail support.

[0105] When the circulating moving parts of the transportation system are in a low-speed motion state, for example, when an escalator is in an idle state, the low-speed circulating moving parts may find it difficult to maintain stable power generation. In this embodiment of the present invention, the power supply further includes: a rechargeable battery 9, which is arranged in the third area; in a first mode, the rechargeable battery 9 provides power alone, or the rechargeable battery 9 provides power together with the generator; in a second mode, at least one of the rechargeable battery 9 and the generator provides power. When the circulating moving parts of the transportation system are in a low-speed motion state, the rechargeable battery 9 serves as a supplementary power source when the output power of the generator of the power source is insufficient; or, the rechargeable battery 9 serves as a backup power source to completely replace the generator in the event of a generator failure or power shortage. Regardless of whether the embodiment of the present invention is in the first mode or the second mode, the rechargeable battery 9 is used as the main power source.

[0106] In an embodiment of the present invention, the power supply further includes: a voltage divider 10, which is disposed in the third area and is used to adjust the output voltage of the power supply so that the voltage output from the power supply meets the voltage requirements of the control unit 11, the first disinfection unit 7, and the second disinfection unit 4. The voltage divider 10 is disposed at the output end of the power supply, and the output end of the voltage divider 10 is connected to the control unit 11, the first disinfection unit 7, and the second disinfection unit 4, respectively.

The rechargeable batteries 9 can be replaced by opening the compartment door of the battery compartment 8. The compartment door is provided with a door lock, which is opened by a key that matches the door lock to prevent the compartment door from being opened due to misoperation. When the transportation system is an escalator or other belt-shaped circulating motion component, the first side wall and the third side wall are fixedly connected to the transportation system through a fixing plate 2, and the second side wall faces away from the circulating motion component. The compartment door is provided on the second side wall, and the battery compartment 8 is provided on the inner side of the second side wall, which is convenient for users to replace the rechargeable batteries 9 and can also make the structure in the frame 1 more compact.

[0108] The frame 1 of the disinfection device of the embodiment of the present invention also includes: a display device 12, which is used to independently display the operation and stop of the first disinfection unit 7, the operation and stop of the second disinfection unit 4, the output power status of the power supply (the power of the generator) and the power level of the rechargeable battery 9. The display device 12 is arranged on the second side wall; the control unit 11 is located between the display device 12 and the first disinfection unit 7. The control unit 11 controls the display content of the display device 12. When the transportation system is an escalator or other device with a belt-shaped circulating motion component, the first side wall and the third side wall are fixedly connected to the transportation system through the fixing plate 2, and the second side wall faces away from the circulating motion component. The display device 12 is arranged on the outside of the second side wall to facilitate personnel to observe the display device 12.

[0109] like Figure 7 As shown, it is an example of the displayed content. When the first disinfection unit 7 performs ultraviolet sterilization, the corresponding icon and text are in the upper left corner of the figure. When the second disinfection unit 4 uses photocatalyst purification, the corresponding icon and text are in the lower left corner of the figure. When the power supply adopts the generator and the rechargeable battery 9, the output power state of the generator corresponds to the icon and text in the upper right corner of the figure, and the battery power corresponds to the icon and text in the lower right corner of the figure. The above icons and texts are only examples of the displayed content. The displayed content can express the corresponding content in the form of patterns, colors, texts, brightness, flashing, etc. For example, based on Figure 7 A possible display logic is given. When the embodiment of the present invention is in the first mode, the generator output power is low and the power generation icon is off. The first disinfection unit 7 is in a low-power operating state and the sterilization icon flashes. The second disinfection unit 4 is stopped and the purification icon is off. When the embodiment of the present invention is in the second mode, the generator output power meets the requirements of the embodiment of the present invention and the power generation icon is lit. The first disinfection unit 7 is in a high-power operating state and the sterilization icon is lit. The second disinfection unit 4 is in operation and the purification icon is lit. The display device 12 can also display other information, such as the time, date, instructions for use, safety precautions, etc.

[0110] The frame 1 of the embodiment of the present invention further includes: a speaker 5, which is used to indicate the operation and stop of the first disinfection unit 7, the operation and stop of the second disinfection unit 4, the output power status of the power supply, and the power level of the rechargeable battery 9 through sound; the speaker 5 is arranged on the second side wall; the second disinfection unit 4 is located on the back of the speaker 5; and the control unit 11 controls the sound emitted by the speaker 5. Exemplarily, the sound signal of the speaker 5 can be in the form of music, voice, prompt sounds with different tones, continuous prompt sounds with different frequencies, etc. The speaker 5 can also provide other information in the form of sound, such as time, date, instructions for use, safety precautions, and when the transportation equipment is an escalator, it can remind passengers to hold the handrails, etc.

[0111] like Figure 6As shown, in one embodiment of the present invention, similar to the disinfection of escalators, the disinfection equipment includes a display device 12, a speaker 5, and a power supply using a generator and a rechargeable battery 9. The generator and the rechargeable battery 9 are used together as a power supply. The controller detects whether the rechargeable battery 9 is installed. When the rechargeable battery 9 is not installed, only the generator is used for power supply. The controller detects the movement state of the handrail and determines the output power of the power supply, thereby switching the working mode of the embodiment of the present invention. A voltage divider 10 is provided at the output end of the power supply to adjust the output voltage and power the control circuit. The control circuit independently controls the working states of the speaker 5, the display device 12, the first disinfection unit 7, and the second disinfection unit 4.

[0112] When the transportation system is in a low-speed motion state, for example, an escalator stops after idling for a certain period of time or stops directly, in an embodiment of the present invention, after the disinfection device enters the first mode, the disinfection device stops working after a preset time period.

[0113] like Figure 1 As shown, when using an embodiment of the present invention to disinfect an escalator, the circulating moving component of the transport system is the escalator's handrail. The ultraviolet light source of the first disinfection unit 7 emits ultraviolet light to disinfect the handrail. Each handrail is equipped with a disinfection device; the disinfection device is located at the entrance and / or exit of the escalator to purify and disinfect the air at the entrance and / or exit of the escalator.

[0114] In summary, the embodiments of the present invention provide a disinfection device and a disinfection method. The structural design of the present invention is reasonable. On the one hand, the circulating motion parts of the transportation system drive the generator to generate electricity, and the generated electricity is stored in the rechargeable battery 9, so that it can power the photocatalyst, the speaker 5, the UVC-LED and the display through the voltage divider 10 and the control circuit, and the control circuit controls them to work. When the transportation system is operating normally, the handrail is continuously irradiated with short-wave ultraviolet light for sterilization through the UVC-LED. When the transportation system stops rotating or rotates slowly, the generator does not work, and the UVC-LED is used to work at low power. It stops working after working for a period of time in the low-power working state, thereby having intelligent power supply and control. The system can sterilize the circulating moving parts of the transportation system when the escalator is operating at a low speed or in a stopped state; the present invention displays the working status of each component and the power indication of the rechargeable battery 9 through the display device 12, and gives voice indication of the working status through the speaker 5, and reminds that the transportation system has been disinfected, thereby adding function display and voice prompt functions to make the working mode clearer and the product intelligent; the present invention draws the outside air near the transportation system into the box body through the air inlet fan and passes it through the photocatalyst filter, irradiates the photocatalyst filter through UVA-LED, sterilizes and filters the air drawn in by the air inlet fan, and then discharges it through the air outlet fan, thereby facilitating the sterilization and purification of the air near the transportation system.
