[0034] The core of the present invention is to provide an odor removal device for plastic tracks. By integrating multiple functions such as cleaning, spraying, and drying, it can achieve efficient removal of odor from plastic tracks, improve the air quality around the plastic tracks, and protect the health of users.

[0035] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", "middle", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0037] In one embodiment of the present invention, Figures 1 to 5 As shown, the vehicle 100 can be walked on the road. The vehicle 100 includes a plate body, two fixed wheels 110 are provided at one end of the plate body, and two casters are provided at the other end. A handrail 120 is fixed to the end of the plate body away from the fixed wheels 110, which is convenient for the operator to control the direction and position of the vehicle 100 during manual pushing or auxiliary traction.

[0038] A holding box 200 is fixed on the vehicle 100, and the holding box 200 contains photocatalyst liquid 300. The volume ratio of photocatalyst to water can be between 1:5 and 1:10, ensuring that sufficient active ingredients react with odorous substances, while also having appropriate fluidity to facilitate uniform spraying by the spray assembly; the vehicle 100 is equipped with a spray assembly that is connected to the bottom end of the holding box 200 and is used to output the photocatalyst liquid 300 to the plastic runway. The spray assembly can atomize the photocatalyst liquid 300 into fine droplets, increase the contact area between the photocatalyst and the odorous substances, and improve the reaction efficiency. The vehicle 100 is equipped with a drying component for drying the photocatalyst liquid 300 on the plastic track. The drying component can accelerate the evaporation of water in the photocatalyst liquid 300, so that the photocatalyst forms a thin film on the surface of the plastic track more quickly and exerts a photocatalytic effect; a cleaning component is installed at one end of the vehicle 100 and on the side of the spray component away from the drying component. The cleaning component can clean leaves, dust and other debris on the surface of the plastic track before spraying the photocatalyst liquid 300, ensuring that the photocatalyst liquid 300 can fully contact the plastic track and improve the odor removal effect.

[0039] Photocatalyst, whose main component is titanium dioxide (TiO2). When the photocatalyst is sprayed on the surface of the plastic track, it acts as a catalyst under the irradiation of light, and can decompose organic pollutants in the air, such as volatile organic compounds (VOCs) such as benzene, toluene, and xylene emitted by the plastic track, and small molecules produced by the aging and decomposition of high molecular polymers, into harmless substances such as carbon dioxide and water, thereby achieving the effect of purifying the air and removing odors. In addition to removing organic pollutants and odors in the air, photocatalysts can also effectively kill bacteria, viruses and other microorganisms in the air and inhibit the growth of mold. Photocatalysts can continue to produce catalytic effects under the action of light. As long as the photocatalyst is not destroyed or washed away by rainwater, it can exert a long-term purification effect. Moreover, it is not consumed during the reaction process and can work for a long time.

[0040] In one embodiment of the present invention, Figures 1 to 3 As shown in Figure 5, the cleaning assembly includes a brush roller 400, which is rotatably connected to the bottom end of the vehicle 100 through a support ear. The brush roller 400 is provided with two brush rollers and the rotation axis has an angle of 30° to 100°. The bristles of the brush roller 400 are overlapped and staggered on one end away from the spray assembly and close to each other, so that when the two brush rollers 400 rotate, they can form a cleaning force toward both sides of the vehicle 100 to clean the debris to both sides of the runway; the two wheels at one end of the vehicle 100 are directional wheels 110, which are transmission-connected to the brush roller 400.

[0041] In one embodiment of the present invention, Figures 1 to 3 As shown, a driven gear 500 is fixed to one end of the brush roller 400 away from each other, and a driving gear 600 is coaxially fixed to one end of the directional wheel 110, and the driving gear 600 is meshed with the driven gear 500. Specifically, the brush roller 400 includes a shaft, two shells with semicircular cross sections, and a plurality of bristles fixed on the surface of the shell (such as Figure 5(As shown), the housing is fixedly connected to the shaft via screws 401, facilitating replacement of the housing and, consequently, the bristles. One end of the shaft extends through the corresponding lug and is fixedly connected to the driven gear 500. The directional wheel 110 is rotatably mounted at the bottom of the vehicle 100 via the support lug. The shaft head of the directional wheel 110 extends through the support lug and is fixedly connected to the driving gear 600. The number of teeth on the driven gear 500 is smaller than that on the driving gear 600, resulting in a transmission ratio of 1:2 to 5. This results in the driven gear 500 rotating faster than the directional wheel 110, improving cleaning efficiency. When the directional wheel 110 rotates, it drives the driving gear 600 to rotate, and the driving gear 600 drives the driven gear 500 to rotate. The driven gear 500 drives the brush roller 400 to rotate through the shaft. The bristles sweep debris such as leaves and dust on the plastic track to both sides of the vehicle 100 (at the same time, debris can be collected with tools such as a broom or a sweeper), preventing the photocatalyst liquid 300 from falling on the debris, resulting in the photocatalyst liquid 300 not being able to fully contact the plastic track.

[0042] In one embodiment of the present invention, Figures 1 to 3 As shown, the drying assembly includes a hot air blower 700 and a bellows 800. The hot air blower 700 is fixedly connected to the vehicle 100. The bellows 800 is fixed to the bottom of the vehicle 100. The bottom of the bellows 800 is provided with a plurality of air outlets 810. The air outlet of the hot air blower 700 is connected to the bellows 800 through a connecting pipe. The hot air generated by the hot air blower 700 enters the bellows 800 through the connecting pipe and is evenly blown out from the air outlet 810 to dry the photocatalyst liquid 300 sprayed on the plastic track.

[0043] In one embodiment of the present invention, Figures 1 to 3 As shown, the spray assembly includes a pump 900, a diverter pipe 1000, a branch pipe 1100 and an atomizing nozzle 1200. The pump 900 is fixedly connected to the vehicle 100, and the liquid inlet of the pump 900 is connected to the bottom end of the inner cavity of the containing box 200 (the liquid inlet and the containing box 200 can be fixedly connected by flange bolts). The liquid outlet of the pump 900 is connected to the diverter pipe 1000 through a guide pipe. The diverter pipe 1000 is connected to a plurality of branch pipes 1100 arranged at intervals along the width direction of the plastic runway. The bottom end of the branch pipe 1100 passes through the vehicle 100 (the two can be fixed) and is fixedly connected to the atomizing nozzle 1200; two baffles 130 are fixed to the bottom end of the vehicle 100, and the atomizing nozzle 1200 is located between the two baffles 130. Baffle 130 blocks most of the wind generated by the rotation of brush roller 400 and the hot air blown out of air outlet 810 of bellows 800, preventing these winds from dispersing the photocatalyst droplets exiting atomizing nozzle 1200. A filter is installed on the diversion tube, and a liquid outlet valve is installed on branch pipe 1100 or the diversion tube. The filter filters impurities in photocatalyst liquid 300 to prevent clogging of atomizing nozzle 1200; the liquid outlet valve controls the flow rate of photocatalyst liquid 300.

[0044] In one embodiment of the present invention, Figure 1 、 2 As shown in Figure 4 , a partition is installed within the container 200, dividing the interior of the container 200 into upper and lower chambers. The upper and lower chambers are connected by a connecting assembly. One side of the upper chamber is connected to a liquid inlet valve 210, and the other side of the lower chamber is connected to a liquid outlet valve 220 for draining excess photocatalyst liquid 300. The upper chamber is connected to an air intake assembly, and an activated carbon plate 1300 is removably connected to the upper chamber. Multiple grille plates 1400 are installed between the activated carbon plate 1300 and the photocatalyst liquid 300. An opening for air exhaust is provided at the top of the upper chamber. When not in use, a rubber stopper can be inserted into the opening to prevent the ingress of debris or small animals. The rubber stopper is connected to the container 200 via a flexible connection to prevent loss. The outer walls of the upper and lower chambers are each provided with a liquid level gauge 1500 to facilitate observation of the photocatalyst liquid 300. If the liquid level gauge 1500 in the upper chamber indicates insufficient photocatalyst liquid 300, it can be added through the liquid inlet valve 210. The activated carbon plate 1300 includes an end plate 1310 at one end. A frame is fixed to one side of the end plate 1310, and the activated carbon plate body is fixed within the frame. The end plate 1310 is fixedly connected to the outer wall of the container 200 via bolts. The container 200 is provided with upper and lower frames 230, with the frame located between the two frames 230. The frames 230 are used to support and guide the frame for easy assembly and disassembly. The grid plate 1400 is used to block the photocatalyst liquid 300, preventing bubbles from bursting and splashing out of the container 200 from the opening.

[0045] In one embodiment of the present invention, Figure 1 and 2 As shown, the connecting assembly includes an elbow connected to a filter that communicates with the upper chamber (the filter and elbow can be fixedly connected to the holding box 200 using flange bolts). The elbow is connected to an on-off valve, and the end of the elbow away from the filter communicates with the lower chamber. During use, the on-off valve is open, allowing the photocatalyst liquid 300 in the upper chamber to flow into the lower chamber.

[0046] In one embodiment of the present invention, Figure 1 and 2 As shown, the air intake assembly includes a fan 1600 fixedly connected to the outer wall of the container 200. The air outlet of fan 1600 is connected to an air inlet pipe, which extends into the bottom end of the upper chamber. The side wall of the bottom end of the air inlet pipe is connected to an air outlet pipe 1700, which is provided with multiple air outlet holes 1701. Fan 1600 draws air and discharges it into the photocatalyst liquid 300 through the air inlet pipe and the air outlet holes 1701 on the air outlet pipe 1700, thereby reducing dust in the air. The air is then filtered by the activated carbon plate 1300 to remove odors before being discharged through the opening.

[0047] In one embodiment of the present invention, Figure 1 and 2 As shown, a support rod is fixed to one end of the vehicle 100, and a hanging ring 1800 is fixed to the support rod for connecting to an external tractor. The tractor can be a tractor head, a pickup truck, a motorized tricycle, an electric vehicle, etc. The tractor and the hanging ring 1800 are connected by a tow rope, which pulls the device to move. During movement, the direction of travel of the vehicle 100 can be adjusted using the handrail 120.

[0048] In one embodiment of the present invention, Figure 1 and 2 As shown, a battery 1900 and a controller 2000 are fixed on the vehicle 100 , and the controller 2000 is electrically connected to the battery 1900 , and the controller 2000 is electrically connected to the fan 1600 , the pump 900 and the hot air blower 700 respectively.

[0049] To use the odor-removing device for a plastic running track, add photocatalyst liquid 300 to the upper chamber of the container 200 via the liquid inlet valve 210. Open the on / off valve of the connecting assembly to allow the photocatalyst liquid 300 to flow into the lower chamber. The device is then connected to a tractor 100 via the hanging ring 1800. The operator adjusts the position and orientation of the tractor 100 using the handrail 120.

[0050] Controller 2000 is activated, and battery 1900 provides energy. Controller 2000 controls pump 900, fan 1600, and hot air blower 700 to operate. A tractor pulls vehicle 100 along the plastic track. The directional wheels 110 rotate, driving gear 600, which in turn drives driven gear 500, which in turn rotates brush roller 400, sweeping debris from the track to both sides.

[0051] Simultaneously, pump 900 draws photocatalyst liquid 300 from the lower chamber of holding box 200 and sprays it evenly onto the plastic track through diverter pipe 1000, branch pipe 1100, and atomizing nozzle 1200. During the spraying process, baffle 130 blocks the wind generated by the rotation of brush roller 400 and the hot air from hot air blower 700, preventing the photocatalyst droplets from being dispersed over a large area.

[0052] The hot air generated by the hot air blower 700 is blown out through the air outlet 810 of the air box 800 to dry the photocatalyst liquid 300 sprayed on the runway, so that the photocatalyst liquid 300 quickly forms a photocatalyst film and exerts a photocatalytic effect.

[0053] The fan 1600 draws air and discharges it into the photocatalyst liquid 300 through the air inlet and outlet holes 1701 on the air outlet pipe 1700, thereby reducing dust in the air. The air is then filtered by the activated carbon plate 1300 to remove odor and is discharged from the opening.

[0054] The various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. Similar parts between the various embodiments can be referred to in conjunction with each other, and the various embodiments can be combined with each other. For the devices disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple.
