Description

Technical Field

[0001] This utility model relates to the field of disinfection chambers, specifically to a head-covered vaporized gas fumigation disinfection chamber. Background Technology

[0002] In medical, biosafety laboratories, and public health emergency scenarios, the disinfection and sterilization of protective headgear is a crucial step in preventing the spread of pathogenic microorganisms. Therefore, disinfection of protective headgear is necessary. Traditional disinfection methods often involve immersion in liquid disinfectants, ultraviolet irradiation, or high-temperature sterilization. While liquid disinfectants such as chlorine-containing disinfectants can kill surface microorganisms, they struggle to penetrate the complex structure of the headgear, potentially leaving corrosive residues that can cause aging and damage to the rubber and plastic components. Ultraviolet disinfection only affects exposed surfaces and cannot penetrate the internal structure, while high-temperature sterilization may deform the headgear material due to excessive heat, affecting its sealing and protective performance. Addressing these issues has become a pressing problem for those skilled in the art. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a vaporized fumigation disinfection chamber for headgear, aiming to improve the traditional disinfection methods for protective headgear, which often involve soaking in liquid agents, ultraviolet irradiation, or high-temperature sterilization. While liquid agents such as chlorine-containing disinfectants can kill surface microorganisms, they are difficult to penetrate the complex structure of the headgear, and may leave residual corrosive liquids, leading to aging and damage to the rubber and plastic parts of the headgear. Ultraviolet disinfection acts on the exposed surface and cannot penetrate the internal structure of the headgear, while high-temperature sterilization may cause deformation of the headgear material due to excessive temperature, affecting its sealing and protective performance.

[0004] This utility model is implemented as follows: a headgear vaporized gas fumigation and disinfection chamber includes a disinfection chamber body, a hydrogen peroxide solution stirring mechanism installed on one side of the disinfection chamber body, and a hydrogen peroxide fumigation and disinfection mechanism installed on the inside of the disinfection chamber body. The hydrogen peroxide solution stirring mechanism and the hydrogen peroxide fumigation and disinfection mechanism are connected and arranged.

[0005] In a preferred embodiment of this utility model, the hydrogen peroxide solution stirring mechanism includes a solution tank installed on one side of the disinfection chamber. A housing is installed on the upper end of the solution tank, and a motor is installed on one side of the housing. A third rod is rotatably installed inside the housing, driven by the motor. A third bevel gear is fixedly sleeved on the outside of the third rod. A rod is rotatably installed at the inner end of the housing, and a bevel gear is fixedly sleeved on the outside of the rod. A second rod is slidably and sealingly connected to the outside of the rod, and a second bevel gear is fixedly sleeved on the outside of the second rod. Both the second bevel gear and the first bevel gear mesh with the third bevel gear and are located at both ends of the third bevel gear. The second rod rotates through the solution tank. A stirring rod is installed on the outside of the rod, and a second stirring rod is installed on the outside of the second rod. The second rod rotates through the housing via a bearing. The motor drives the third rod, causing the third bevel gear to rotate. The third bevel gear causes the bevel gear and the second bevel gear to rotate in different directions, causing the rod and the second rod to rotate in different directions, and causing the stirring rod and the second stirring rod to rotate in different directions. This ensures that the liquid in the solution tank is stirred more evenly, preventing the hydrogen peroxide solution in the solution tank from becoming uneven in concentration due to standing for a period of time, which would affect the spraying and fumigation effect of the hydrogen peroxide fumigation and disinfection mechanism, and thus affect the disinfection effect on the headgear.

[0006] In the preferred embodiment of this utility model, multiple sets of stirring rods are provided, which are arranged on both sides of the rod body. All sets of stirring rods are inclined and symmetrically arranged with respect to the center of the rod body. The stirring effect is enhanced by the inclined and symmetrical stirring rods. At the same time, the stirring rods continuously flip people upwards, which further enhances the stirring effect.

[0007] In a preferred embodiment of this invention, a hydrogen peroxide solution inlet pipe is provided at the upper end of the solution tank.

[0008] In a preferred embodiment of this utility model, the hydrogen peroxide fumigation disinfection mechanism includes a pump body installed inside the disinfection chamber. A connecting pipe is installed on one side of the solution tank, and the connecting pipe is connected to the input end of the pump body. A liquid delivery pipe is installed at the output end of the pump body. A flash evaporator is installed inside the disinfection chamber, and the input end of the flash evaporator is connected to the liquid delivery pipe. An air delivery pipe is installed at the output end of the flash evaporator. A connecting box is installed on the inner wall of the disinfection chamber, and the connecting box is connected to the air delivery pipe. A pipe body is rotatably installed at the inner end of the disinfection chamber. A second motor is installed at the upper end of the disinfection chamber, and the pipe body is driven by the second motor. The connecting box is sealed and slidably sleeved on the outside of the pipe body. The pipe body is provided with... The device has an air inlet and the pipe body is located inside the connecting box. A connecting plate is installed at the bottom of the pipe body, and a nozzle is installed at the bottom of the connecting plate. The connecting pipe is equipped with a solenoid valve. The liquid stirred in the solution tank is sent into the flash evaporator through the pump body, the connecting pipe, and the liquid delivery pipe. The hydrogen peroxide solution is flash-vaporized in the flash evaporator and sent into the connecting box through the air delivery pipe. The gas entering the connecting box is sent into the pipe body through the air inlet and enters the connecting plate. It is then sprayed through the nozzle to fumigate and disinfect the hood. At the same time, a second motor drives the pipe body, which causes the connecting plate to drive the nozzle to rotate, thereby increasing the spray range of the nozzle and making the vaporized hydrogen peroxide more even in the disinfection chamber. This enhances the disinfection effect of the hood, reduces the disinfection time, and improves work efficiency.

[0009] In a preferred embodiment of this invention, multiple sets of nozzles are arranged in a uniform array on the connecting disk.

[0010] In a preferred embodiment of this utility model, a sealed door is hinged to one side of the disinfection chamber.

[0011] In a preferred embodiment of this utility model, a pressure sensor is installed on the inner wall of the disinfection chamber, and a pressure relief valve is provided on one side of the disinfection chamber.

[0012] In a preferred embodiment of this utility model, a hanging rod is installed on the inner wall of the disinfection chamber, a hanging hook is installed on one side of the hanging rod, and a placement board is installed on the inner wall of the disinfection chamber.

[0013] The beneficial effects of this utility model are as follows: The hood fumigation and disinfection chamber obtained by the above design involves feeding the solution tank through a hydrogen peroxide solution inlet pipe, placing the hood to be disinfected into the chamber, and then rotating the third bevel gear via a motor-driven third rod. This causes the third bevel gear to rotate in different directions, resulting in the rod and the second rod rotating in different directions, and the stirring rod and the second stirring rod rotating in different directions. This ensures that the liquid in the hydrogen peroxide solution tank is more evenly stirred. A pump, in conjunction with a connecting pipe and a delivery pipe, sends the stirred liquid from the solution tank into a flash evaporator. The flash evaporator vaporizes the hydrogen peroxide solution and sends it into a connecting box via a gas delivery pipe. The gas entering the connecting box is then sent into the pipe body through the air inlet and into the connecting disc, where it is sprayed through nozzles to fumigate and disinfect the hood. Simultaneously, a second motor drives the pipe body, causing the connecting disc to rotate the nozzles, resulting in a more even and rapid distribution of hydrogen peroxide gas within the disinfection chamber. The device uses a hydrogen peroxide solution stirring mechanism to ensure more uniform stirring of the hydrogen peroxide solution, preventing the disinfection effect from being reduced due to uneven concentration. The hydrogen peroxide fumigation disinfection mechanism allows the hydrogen peroxide gas to be distributed more quickly and evenly within the disinfection chamber, thereby improving disinfection efficiency and effectiveness.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Please see Figures 1-3 The present invention provides a technical solution: a headgear vaporized gas fumigation and disinfection chamber, characterized in that it includes a disinfection chamber body 100, a hydrogen peroxide solution stirring mechanism 200 installed on one side of the disinfection chamber body 100, a hydrogen peroxide fumigation and disinfection mechanism 300 installed on the inner side of the disinfection chamber body 100, and the hydrogen peroxide solution stirring mechanism 200 and the hydrogen peroxide fumigation and disinfection mechanism 300 are connected.

[0019] In some specific implementations, the hydrogen peroxide solution stirring mechanism 200 includes a solution tank 210, which is installed on one side of the disinfection chamber 100. A housing 220 is installed on the upper end of the solution tank 210, and a motor 250 is installed on one side of the housing 220. A third rod 280 is rotatably installed inside the housing 220 and is driven by the motor 250. A third bevel gear 281 is fixedly sleeved on the outside of the third rod 280. A rod 230 is rotatably installed inside the housing 220 and is fixedly sleeved on the outside of the rod 230. A second rod 260 is slidably sealed to the outside of the rod 230 and is fixedly sleeved on the outside of the second rod 260. Both the second bevel gear 261 and the bevel gear 231 mesh with the third bevel gear 281 and are located at both ends of the third bevel gear 281. The second rod 260 rotates... A stirring rod 240 is installed outside the rod 230, which penetrates the solution tank 210. A second stirring rod 270 is installed outside the second rod 260. The second rod 260 rotates through the housing 220 via a bearing. The motor 250 drives the third rod 280, which in turn drives the third bevel gear 281 to rotate. The third bevel gear 281 causes the bevel gears 231 and 261 to rotate in different directions, which in turn causes the rods 230 and 260 to rotate in different directions, and the stirring rods 240 and 270 to rotate in different directions. This ensures that the liquid in the solution tank 210 is stirred more evenly, preventing the hydrogen peroxide solution in the solution tank 210 from becoming uneven in concentration due to standing for a period of time, which would affect the spraying and fumigation effect of the hydrogen peroxide fumigation and disinfection mechanism 300 and thus the disinfection effect on the headgear.

[0020] In some specific implementations, multiple sets of stirring rods 240 are provided, with multiple sets of stirring rods 240 arranged on both sides of the rod body 230. All sets of stirring rods 240 are inclined and symmetrically arranged with respect to the center of the rod body 230. The stirring effect is enhanced by the inclined and symmetrical stirring rods 240. At the same time, the stirring rods continuously turn the personnel upwards, further enhancing the stirring effect.

[0021] In some specific implementations, a hydrogen peroxide solution inlet pipe 290 is provided at the upper end of the solution tank 210.

[0022] In some specific implementations, the hydrogen peroxide fumigation disinfection mechanism 300 includes a pump body 310, which is installed inside the disinfection chamber 100. A connecting pipe 311 is installed on one side of the solution tank 210, and the connecting pipe 311 is connected to the input end of the pump body 310. A liquid delivery pipe 320 is installed at the output end of the pump body 310. A flash evaporator 330 is installed inside the disinfection chamber 100, and the input end of the flash evaporator 330 is connected to the liquid delivery pipe 320. An air supply pipe 340 is installed at the output end of the 30-type disinfection chamber. A connecting box 350 is installed on the inner wall of the disinfection chamber 100, and the connecting box 350 and the air supply pipe 340 are connected. A pipe body 370 is rotatably installed at the inner end of the disinfection chamber 100. A second motor 360 is installed at the upper end of the disinfection chamber 100, and the pipe body 370 is driven by the second motor 360. The connecting box 350 is sealed and slidably sleeved on the outside of the pipe body 370. The pipe body 370 is provided with an air inlet 371 and the pipe body 370 is provided with... The device is placed inside the connecting box 350. A connecting plate 380 is connected to the bottom of the pipe body 370, and a nozzle 390 is installed at the bottom of the connecting plate 380. A solenoid valve is installed in the connecting pipe 311. The liquid stirred in the solution tank 210 is sent to the flash evaporator 330 through the pump body 310, the connecting pipe 311, and the liquid delivery pipe 320. The hydrogen peroxide solution is flash vaporized in the flash evaporator 330 and sent to the connecting box 350 through the gas delivery pipe 340. The gas entering the connecting box 350 is sent into the pipe body 370 through the air inlet 371 and into the connecting plate 380. It is then sprayed through the nozzle 390 to fumigate and disinfect the headgear. At the same time, the second motor 360 drives the pipe body 370 to make the connecting plate 380 drive the nozzle 390 to rotate, which increases the spraying range of the nozzle 390 and makes the vaporized hydrogen peroxide more uniform in the disinfection chamber 100, thereby enhancing the disinfection effect of the headgear, reducing the disinfection time, and improving work efficiency.

[0023] In some specific implementations, the nozzles 390 are provided in multiple sets and uniformly arranged on the connecting disk 380.

[0024] In some specific implementation schemes, a sealing door 110 is hinged to one side of the disinfection chamber body 100.

[0025] In some specific implementation schemes, a pressure sensor 120 is installed on the inner wall of the disinfection chamber 100, and a pressure relief valve 130 is provided on one side of the disinfection chamber 100.

[0026] In some specific implementation schemes, a hanging rod 140 is installed on the inner wall of the disinfection chamber 100, a hanging hook 150 is installed on one side of the hanging rod 140, and a placement plate 160 is installed on the inner wall of the disinfection chamber 100.

[0027] Working principle: Hydrogen peroxide solution is fed into solution tank 210 through inlet pipe 290. The headgear to be disinfected is placed into disinfection chamber 100. Motor 250 drives third rod 280, causing third bevel gear 281 to rotate. Third bevel gear 281, in turn, causes bevel gears 231 and 261 to rotate in opposite directions. This, in turn, causes rods 230 and 260 to rotate in opposite directions, and consequently, stirring rods 240 and 270 to rotate in opposite directions. This ensures more uniform stirring of the liquid in hydrogen peroxide solution tank 210. Pump 310... The liquid stirred in the solution tank 210 is sent to the flash evaporator 330 through the connecting pipe 311 and the liquid delivery pipe 320. The hydrogen peroxide solution is flash vaporized in the flash evaporator 330 and sent to the connecting box 350 through the gas delivery pipe 340. The gas entering the connecting box 350 is sent into the pipe body 370 through the air inlet 371 and enters the connecting plate 380. It is then sprayed through the nozzle 390 to fumigate and disinfect the headgear. At the same time, the second motor 360 drives the pipe body 370 to make the connecting plate 380 drive the nozzle 390 to rotate, so that the hydrogen peroxide gas is more evenly and quickly distributed in the disinfection chamber 100.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
