It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] For example, see Figures 1 to 9 The present invention provides a technical solution for a disinfection device applied to an elevator car: it includes an elevator car body 1 and an equipment shell 2, the upper part of the inner wall of the elevator car body 1 is fixedly connected to the outer wall of the equipment shell 2, a ventilation fan 4 is arranged inside the equipment shell 2, a box body 3 is arranged on the side of the equipment shell 2 close to the ventilation fan 4, an ultraviolet lamp 5 is arranged on the side of the equipment shell 2 close to the box body 3, an ozone device 6 is arranged on the side of the equipment shell 2 close to the ultraviolet lamp 5, a mounting pipe 8 is rotatably connected through the middle position of the bottom of the box body 3, a nozzle 81 is fixedly connected to the outer wall of the bottom of the mounting pipe 8, a spraying mechanism is arranged inside the box body 3, and the spraying mechanism includes a bidirectional motor 31, and the outer wall at the top of the bidirectional motor 31 is fixedly connected to the upper part of the box body 3.

[0031] The ultraviolet lamp 5 has high efficiency and broad spectrum sterilization, and has a good killing effect on various bacteria and viruses. The ozone emitted by the ozone device 6 has a fast disinfection speed and strong sterilization ability, and has a good disinfection effect on the air and the surface of objects. The combination of the two can kill bacteria and viruses in the elevator car body 1 more comprehensively.

[0032] Embodiment 2, on the basis of embodiment 1, the inner wall of the box body 3 is fixedly connected with a fixing plate 36, the outer wall at the bottom of the fixing plate 36 is fixedly connected with an airbag 35, the outer wall at the bottom of the airbag 35 is fixedly connected with a push plate 37, the outer wall of the push plate 37 is slidably connected to the inner wall of the box body 3, the output end of the bidirectional motor 31 is fixedly connected with a mounting frame 32, the inner wall of the mounting frame 32 is rotatably connected with a pressure roller 33, the outer wall of the pressure roller 33 is rotatably connected to the outer wall of the top of the fixing plate 36, the outer wall of the top of the fixing plate 36 is provided with a groove, the inside of the four grooves is fixedly connected with an inflatable ball 34, the outer wall of the bottom of the inflatable ball 34 is fixedly connected with an air outlet pipe 38, the outer wall of the air outlet pipe 38 passes through the inside of the fixing plate 36 and the inside of the airbag 35 and is fixedly connected, and the outer wall of the pressure roller 33 is in active contact with the outer wall of the inflatable ball 34.

[0033] The ozone decomposition agent inside the box body 3 is sprayed out through the nozzle 81. The spraying of the ozone decomposition agent helps to decompose the ozone inside the elevator car body 1, thereby preventing potential threats to human health. At the same time, other harmful substances in the air are decomposed or adsorbed to a certain extent, which plays a role in purifying the air, ensuring that the air quality inside the elevator car body 1 after disinfection is improved in time, providing passengers with a safer and healthier elevator environment.

[0034] Embodiment three, based on embodiment two, the output end of the bidirectional motor 31 is fixedly connected to the main shaft 7, the outer wall of the main shaft 7 is fixedly connected to the fan blade 2 71, the outer wall of the fan blade 2 71 is rotatably connected to the inside of the mounting tube 8, and the outer wall of the main shaft 7 is fixedly connected to the limiting raised ring 72.

[0035] Through the rotation of the fan blade 2 71 on the mounting tube 8, when the ozone decomposer passes through the fan blade 2 71, the flow rate of the ozone decomposer will be affected due to the obstruction of the fan blade 2 71, thereby generating a certain pressure. The increase in pressure helps to spray the ozone decomposer more effectively and improve the spraying effect. At the same time, the ozone decomposer is evenly mixed to ensure that the ozone decomposer can fully contact and react with the ozone in the air.

[0036] Embodiment 4, on the basis of embodiment 3, the inner wall of the mounting tube 8 is fixedly connected with the limiting tooth 82, the outer wall of the limiting tooth 82 is movably plugged into the outer wall of the limiting raised ring 72, the outer wall of the bottom of the limiting raised ring 72 is fixedly connected with the arc scraper 73, the outer wall on one side of the arc scraper 73 is in movably contact with the inner wall of the nozzle 81, the outer wall on the top of the limiting raised ring 72 is fixedly connected with a cleaning plate, the outer wall on one side of the cleaning plate is in movably contact with the inner wall of the mounting tube 8.

[0037] By scraping off the ozone decomposing agent on the inner wall of the installation tube 8 and the nozzle 81, clogging of the nozzle 81 is avoided when the nozzle 81 is working, and accordingly the ozone decomposing agent is sprayed out through the nozzle 81 more quickly and effectively. At the same time, through the operation of the cleaning plate and the arc scraper 73, the deposits on the installation tube 8 and the nozzle 81 can be scraped off and sprayed out from the nozzle 81 to clean the inner wall of the nozzle 81;

[0038] By rotating the nozzle 81, the centrifugal force generated by the rotation of the nozzle 81 can be used to spray the ozone decomposer farther, which helps to ensure that the ozone decomposer can evenly cover a larger spatial area, thereby accelerating the decomposition process of ozone and reducing the ozone concentration in the air, thereby achieving the air purification goal more quickly. At the same time, the spraying efficiency and uniformity can be improved, which can reduce the amount of ozone decomposer used.

[0039] Embodiment 5, on the basis of embodiment 1, the outer wall of the top of the fixed plate 36 is provided with an exhaust groove 10, the outer wall of the bottom of the exhaust groove 10 is connected with the outer wall of the top of the airbag 35, the inside of the exhaust groove 10 is fixedly connected with a support rod 102, the outer wall of the support rod 102 is rotatably connected with the adjustment plate 101, one side of the inner wall of the exhaust groove 10 is fixedly connected with a baffle rod, the bottom of the baffle rod is in active contact with the outer wall of the top of the adjustment plate 101, the outer wall of the adjustment plate 101 is fixedly connected with a sealing ring, and the outer wall of one end of the adjustment plate 101 A square groove is provided, a rotating rod 104 is fixedly connected inside the square groove, a rotating plate 103 is rotatably connected to the outer wall of the rotating rod 104, a torsion spring is provided on the outer wall of the rotating rod 104, a receiving groove is provided on the other side of the inner wall of the exhaust groove 10, an elastic block 106 is fixedly connected inside the receiving groove, a sealing plate 105 is fixedly connected to the outer wall at one end of the elastic block 106, the outer wall of the sealing plate 105 is slidably connected to the inside of the receiving groove, and the outer wall at one end of the sealing plate 105 is in active contact with the outer wall at the bottom of the adjusting plate 101.

[0040] By releasing the gas inside the airbag 35, when the gas inside the airbag 35 is reduced, the airbag 35 will be deflated, thereby reducing the thrust of the airbag 35 on the push plate 37, so that the air pressure inside the box 3 becomes smaller, and the spraying of the ozone decomposition agent by the nozzle 81 is stopped, thereby realizing automatic adjustment of the spraying action of the nozzle 81, which is convenient for controlling the operation of the nozzle 81.

[0041] Embodiment 6. On the basis of embodiment 4, the outer wall of the mounting tube 8 is fixedly connected with teeth 9, the outer wall of the teeth 9 is meshingly connected with a fast wheel 92, the axis positions of the two fast wheels 92 are fixedly connected with support shafts, the outer walls of the tops of the two support shafts are rotatably connected with the outer wall of the bottom of the box body 3, the outer wall of the fast wheel 92 is meshingly connected with a gear 93, the axis positions of the two gears 93 are fixedly connected with a rotating shaft 94, the outer wall of the top of the rotating shaft 94 is rotatably connected with the outer wall of the bottom of the box body 3, and the outer wall of the rotating shaft 94 is fixedly connected with a fan blade 91.

[0042] The wind force generated by the rotation of the fan blade 91 can quickly drive the air flow inside the elevator car body 1, which helps the ozone decomposer to be dispersed throughout the entire elevator car body 1 space more quickly. The evenly dispersed ozone decomposer can more effectively contact the ozone molecules in the air, thereby improving the decomposition efficiency. At the same time, the collision chance between the ozone molecules and the decomposer particles is enhanced. By increasing the collision frequency, the decomposition process of ozone can be accelerated.

[0043] The working principle and use process of the present invention are as follows: during operation, first, when there is no personnel inside the elevator car body 1, the interior of the elevator car body 1 is disinfected by the operation of the ultraviolet lamp 5 and the ozone device 6. The ultraviolet lamp 5 has high efficiency and broad-spectrum sterilization, and has a good killing effect on a variety of bacteria and viruses. The ozone emitted by the ozone device 6 has a fast disinfection speed and strong sterilization ability, and has a good disinfection effect on the air and the surface of objects. The combination of the two can more comprehensively kill the bacteria and viruses in the elevator car body 1.

[0044] After the disinfection of the interior of the elevator car body 1 is completed, the movement of the two can be stopped, and the bidirectional motor 31 is started. When the bidirectional motor 31 rotates clockwise, the mounting frame 32 and the main shaft 7 can be driven to rotate, and the mounting frame 32 drives the pressure roller 33 to rotate on the fixed plate 36, and then through the movement of the pressure roller 33, when the pressure roller 33 moves to the position of the inflatable ball 34, the inflatable ball 34 can be squeezed, forcing the gas inside the inflatable ball 34 to enter the air bag 35 through the outlet pipe 38. When the gas is added inside the air bag 35 and it becomes bulging, due to the gap between the fixed plate 36 and the box body 3 The fixed connection can only make the airbag 35 push the push plate 37 downward to move. Under the push of the push plate 37, the air pressure inside the box 3 is enhanced, so that the ozone decomposer inside the box 3 is sprayed out through the nozzle 81. The spraying of the ozone decomposer helps to decompose the ozone inside the elevator car body 1, thereby preventing potential threats to human health. At the same time, other harmful substances in the air are decomposed or adsorbed to a certain extent, which plays a role in purifying the air, ensuring that the air quality inside the elevator car body 1 after disinfection is improved in time, providing passengers with a safer and healthier elevator environment.

[0045] It should be noted that a one-way valve is provided inside the air outlet pipe 38 to prevent the gas inside the airbag 35 from entering the inflatable ball 34 when the inflatable ball 34 is restored after the gas inside the inflatable ball 34 enters the airbag 35 .

[0046] Then, through the rotation of the main shaft 7, the fan blade 2 71 and the limiting raised ring 72 can be driven to rotate at the same time, and then through the rotation of the fan blade 2 71 on the mounting tube 8, when the ozone decomposer passes through the fan blade 2 71, the flow rate of the ozone decomposer will be affected due to the obstruction of the fan blade 2 71, thereby generating a certain pressure. The increase in pressure helps to spray the ozone decomposer more effectively and improve the spraying effect. At the same time, the ozone decomposer is evenly mixed to ensure that the ozone decomposer can fully contact and react with the ozone in the air.

[0047] By rotating the limiting raised ring 72, the cleaning plate and the arc scraper 73 can be driven to rotate on the inner walls of the mounting tube 8 and the nozzle 81 at the same time, so that the ozone decomposition agent on the inner walls of the mounting tube 8 and the nozzle 81 can be scraped off, avoiding blockage when the nozzle 81 is working, and correspondingly making the ozone decomposition agent sprayed out through the nozzle 81 more quickly and effectively. At the same time, through the operation of the cleaning plate and the arc scraper 73, the sediment on the mounting tube 8 and the nozzle 81 can be scraped off and sprayed out with the nozzle 81 to clean the inner wall of the nozzle 81.

[0048] By means of the movable connection between the limiting protrusion ring 72 and the limiting teeth 82, when the limiting protrusion ring 72 rotates, the limiting teeth 82 can drive the mounting tube 8 to rotate accordingly, and then the nozzle 81 can be rotated accordingly through the rotation of the mounting tube 8, so that the centrifugal force generated by the rotation of the nozzle 81 can be used to spray the sprayed ozone decomposition agent farther, which helps to ensure that the ozone decomposition agent can evenly cover a larger spatial area, correspondingly accelerate the decomposition process of ozone, reduce the ozone concentration in the air, and thus achieve the air purification goal faster. At the same time, the spraying efficiency and uniformity can be improved, and the amount of ozone decomposition agent used can be reduced.

[0049] By means of the teeth 9 fixedly connected to the outer wall of the mounting tube 8, when the mounting tube 8 rotates, the teeth 9 can drive the fast wheel 92 to rotate accordingly, and then by means of the meshing connection between the fast wheel 92 and the gear 93, the gear 93 can be driven to move accordingly when the fast wheel 92 rotates, so that the gear 93 drives the rotating shaft 94 to rotate, and the rotating shaft 94 can drive the fan blade 91 to work accordingly. The wind force generated by the rotation of the fan blade 91 can quickly drive the air flow inside the elevator car body 1, which helps the ozone decomposer to be dispersed to the entire elevator car body 1 space more quickly. The evenly dispersed ozone decomposer can more effectively contact the ozone molecules in the air, thereby improving the decomposition efficiency. At the same time, the collision chance between the ozone molecules and the decomposer particles is enhanced, and the decomposition process of the ozone can be accelerated by increasing the collision frequency.

[0050] When the mounting frame 32 is driven to rotate counterclockwise by the bidirectional motor 31, when the pressure roller 33 rotates to contact the rotating plate 103 and continues to move, the rotating plate 103 can be pushed to drive the adjusting plate 101 to rotate on the supporting rod 102, and then the sealing plate 105 is pushed to squeeze the elastic block 106 into the interior of the sealing plate 105 through the movement of the adjusting plate 101, and the exhaust groove 10 is opened, so that the gas inside the airbag 35 can be released. When the gas inside the airbag 35 is reduced, the airbag 35 will be deflated, thereby reducing the thrust of the airbag 35 on the push plate 37, so that the air pressure inside the box body 3 becomes smaller, and the spraying of the ozone decomposition agent by the nozzle 81 is stopped, thereby realizing the automatic adjustment of the spraying action of the nozzle 81, which is convenient for controlling the operation of the nozzle 81.

[0051] It should be noted that: after the pressure roller 33 moves clockwise to the position of the exhaust groove 10, when it contacts the rotating plate 103, the rotating plate 103 can be rotated on the rotating rod 104, so that the rotating plate 103 is flush with the top of the fixed plate 36, which is convenient for the pressure roller 33 to pass through. The torsion spring arranged on the rotating rod 104 can drive the rotating plate 103 to return to its original position after the pressure roller 33 passes through.

[0052] After the ozone decomposer is sprayed, the ventilation fan 4 is started again. The ventilation fan 4 not only promotes the flow of air, but also enhances the mixing of air inside the elevator car body 1, which helps to discharge the decomposed ozone and other harmful gases out of the car, and introduce fresh air at the same time. This circulation flow improves the overall efficiency of the air purification system, so that the air quality inside the elevator car body 1 is rapidly improved. Through the cooperation of the ventilation fan 4 and the ozone decomposer, the efficiency of dissipating the ozone odor inside the elevator car body 1 is increased.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
