Description

Technical Field

[0001] This invention relates to the field of infectious disease prevention technology, and in particular to an infectious disease prevention and disinfection device. Background Technology

[0002] Infectious diseases are a class of diseases caused by various pathogens that can be transmitted between humans, animals, or between humans and animals. Most pathogens are microorganisms, while a small portion are parasites; diseases caused by parasites are also called parasitic diseases. An infectious disease is an infectious disease that can be transmitted from one person or other species to another through various routes. Usually, this type of disease... Infected individuals can be infected through direct contact with their bodily fluids and excrement, or through objects contaminated by them. Transmission can occur via air, water, food, contact, soil, and vertical transmission. Disinfection refers to methods that kill pathogenic microorganisms, but not necessarily bacterial spores. Chemical methods are typically used to achieve disinfection, and the chemical agents used for disinfection are called disinfectants. Sterilization refers to methods that kill all microorganisms (including bacterial spores) on an object. When treating patients, medical staff often need to disinfect various medical supplies.

[0003] However, existing infectious disease prevention and disinfection devices mainly rely on chemical disinfectants for spraying or wiping. For precision instruments and medical protective equipment, after spraying or wiping, they often need to be air-dried for a long time to remove residues, resulting in low disinfection efficiency. Furthermore, the over-reliance on chemical disinfectants as a single disinfection method lacks the synergistic effect of physical and chemical disinfection, leading to insufficient overall epidemic prevention and disinfection methods and difficulty in achieving thorough sterilization. Therefore, an infectious disease prevention and disinfection device is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as low disinfection efficiency, over-reliance on chemical disinfectants as a single disinfection method, lack of synergy between physical and chemical disinfection, resulting in insufficient overall epidemic prevention and disinfection measures and difficulty in achieving thorough sterilization. Therefore, this invention proposes an infectious disease prevention and disinfection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A disinfection device for infectious disease prevention includes a disinfection chamber. A liquid storage tank is fixedly connected to the bottom of the disinfection chamber. A protective box is fixedly connected to the bottom of the liquid storage tank. A drive motor is fixedly connected to the bottom of the protective box. A first rotating shaft is fixedly connected to the output end of the drive motor. A first rotating wheel is fixedly connected to the upper part of the outer surface of the first rotating shaft. A second rotating wheel is rotatably connected to the outer surface of the first rotating wheel via a belt. A first screw is fixedly connected to the outer wall of the second rotating wheel. A first movable seat is threadedly connected to the outer surface of the first screw. A spray head is fixedly connected to the outer wall of the first movable seat. The top of the spray head is fixedly connected to... The device includes a telescopic tube, with an infusion tube fixedly connected to the end of the telescopic tube away from the spray head. A delivery pump is fixedly connected to the outer wall of the infusion tube. A drive gear is fixedly connected to the lower end of the outer surface of the first rotating shaft. A driven gear meshes with the outer surface of the drive gear. A second rotating shaft is fixedly connected to the outer wall of the driven gear. A third rotating wheel is fixedly connected to the upper end of the outer surface of the second rotating shaft. A fourth rotating wheel is rotatably connected to the outer surface of the third rotating wheel via a belt. A second screw is fixedly connected to the outer wall of the fourth rotating wheel. A second movable seat is threadedly connected to the outer surface of the second screw. An ultraviolet lamp is fixedly connected to the outer wall of the second movable seat.

[0006] Furthermore, a blower is fixedly connected to the outer wall of the disinfection box, and a heater is fixedly connected to the output end of the blower through an air inlet pipe. Air guide pipes are fixedly installed on the outer walls of both ends of the heater. The end of the air guide pipe away from the heater passes through the outer wall of the disinfection box and extends into the interior, where it is fixedly connected to a hot air hood. This has three effects: first, it keeps the items dry, avoiding the growth of bacteria caused by a humid environment, and enabling immediate use after disinfection; second, the high-temperature hot air itself has an auxiliary sterilization effect; and third, it solves the problem of items becoming damp after traditional spray disinfection and requiring secondary drying, thus improving ease of use.

[0007] Furthermore, an adsorption hood is fixedly connected to the top wall inside the disinfection chamber, and an air guide pipe is fixedly connected to the outer wall of the adsorption hood. A filter box is fixedly connected to the end of the air guide pipe away from the adsorption hood, and an exhaust fan is installed on the outer surface of the air guide pipe. This ensures that the disinfection process is carried out under a slightly negative pressure and closed-loop circulation state, effectively preventing the leakage of disinfectant volatile gases and aerosols that could pose a health threat to operators and avoiding secondary pollution to the surrounding environment.

[0008] Furthermore, a filter cotton plate and an activated carbon plate are fixedly installed inside the filter box, and an exhaust pipe is fixedly connected to the outer wall of the end of the filter box away from the exhaust fan.

[0009] Furthermore, the end of the telescopic tube away from the spray head penetrates the inner wall of the disinfection box and extends to the outside, while the end of the infusion tube away from the telescopic tube penetrates the outer wall of the storage tank and extends to the inside.

[0010] Furthermore, the tops of both the first and second rotating shafts penetrate the bottom of the reservoir and extend into the reservoir. Both the first and second rotating shafts are rotatably connected to the reservoir via bearings.

[0011] Furthermore, stirring rods are fixedly connected to the outer walls of both the first and second rotating shafts. A partition is provided between the first, second, third, and fourth rotating wheels and the stirring rods. The partition is fixedly connected to the inner wall of the storage tank. The stirring rods can fully mix and blend the water and disinfectant, avoiding the disinfectant settling and poor disinfection effect due to prolonged disuse.

[0012] Furthermore, the driving gear and driven gear are housed inside the protective box, and the stirring rod is housed inside the liquid storage tank.

[0013] Furthermore, the inner walls on both sides of the disinfection box are provided with limiting grooves, and sliding blocks are slidably connected inside the limiting grooves. The sliding blocks are fixedly connected to the first movable seat and the second movable seat.

[0014] Furthermore, the disinfection box is hinged to a sealed door on the front, and a controller is fixedly installed on the outer wall of the sealed door. The controller is electrically connected to the drive motor, the delivery pump, the blower, the heater, and the exhaust fan.

[0015] The present invention has the following beneficial effects: In this invention, by using a drive motor, a first rotating shaft, a first rotating wheel, a second rotating wheel, a first screw, a spray head, a delivery pump, and a telescopic pipe, along with a drive gear, a driven gear, a second rotating shaft, a third rotating wheel, a fourth rotating wheel, a second screw, and an ultraviolet lamp, the spray head and ultraviolet lamp can cover the entire space inside the disinfection chamber, effectively overcoming disinfection dead zones and ensuring that items placed inside the chamber are evenly covered by disinfectant and fully irradiated by ultraviolet light, thus improving the comprehensiveness and thoroughness of disinfection. Furthermore, through a blower, a heater, and a hot air hood, the spraying-irradiation-drying process is completed for precision instruments and medical protective equipment, achieving a complementary advantage between chemical and physical disinfection and improving the disinfection effect of the device.

Air guide pipes 24 are fixedly installed on the outer walls of both ends of the heater 23. The end of the air guide pipe 24 away from the heater 23 passes through the outer wall of the disinfection chamber 1 and extends into the interior, where a hot air hood 25 is fixedly connected.

[0021] An adsorption hood 26 is fixedly connected to the top wall inside the disinfection chamber 1. An air guide pipe 27 is fixedly connected to the outer wall of the adsorption hood 26. A filter box 28 is fixedly connected to the end of the air guide pipe 27 away from the adsorption hood 26. An exhaust fan 29 is installed on the outer surface of the air guide pipe 27.

[0022] Inside the filter box 28, filter cotton plates and activated carbon plates are fixedly installed respectively, and an exhaust pipe is fixedly connected to the outer wall of the end of the filter box 28 away from the exhaust fan 29.

[0023] The end of the telescopic tube 11 away from the spray head 10 passes through the inner wall of the disinfection box 1 and extends to the outside, while the end of the infusion tube 12 away from the telescopic tube 11 passes through the outer wall of the storage tank 2 and extends to the inside.

[0024] The top of both the first rotating shaft 5 and the second rotating shaft 16 penetrates the bottom of the liquid storage tank 2 and extends into the interior of the liquid storage tank 2. Both the first rotating shaft 5 and the second rotating shaft 16 are rotatably connected to the liquid storage tank 2 through bearings.

[0025] Stirring rods 30 are fixedly connected to the outer walls of the first rotating shaft 5 and the second rotating shaft 16. A partition is provided between the first rotating wheel 6, the second rotating wheel 7, the third rotating wheel 17 and the fourth rotating wheel 18 and the stirring rods 30.

[0027] The inner walls on both sides of the disinfection box 1 are provided with limiting grooves, and sliding blocks are slidably connected inside the limiting grooves. The sliding blocks are fixedly connected to the first movable seat 9 and the second movable seat 20.

[0028] The front of the disinfection chamber 1 is hinged with a sealing door 31. A controller 32 is fixedly installed on the outer wall of the sealing door 31. The controller 32 is electrically connected to the drive motor 4, the delivery pump 13, the blower 22, the heater 23, and the exhaust fan 29.

[0029] In this embodiment, the storage tank 2 is first filled with disinfectant, then the sealing door 31 is opened, the items to be disinfected are placed into the disinfection chamber 1, the door is closed, and the delivery pump 13 is started via the controller 32 to deliver the disinfectant in the storage tank 2 to the spray head 10 through the infusion tube 12 and the telescopic tube 11. The spray head 10 is used to spray and disinfect precision instruments or medical protective equipment. At the same time, the drive motor 4 is started, which drives the first rotating shaft 5 to start rotating. The rotating first rotating shaft 5 drives the first rotating wheel 6 to rotate. The rotating wheel 6 drives the second rotating wheel 7 to rotate via a belt. The rotating second rotating wheel 7 drives the first screw 8 to rotate. Driven by the first screw 8, the first moving seat 9 begins to move up and down within the disinfection chamber 1, simultaneously causing the spray head 10 to move up and down, providing dynamic and full-coverage spraying of the items, thus improving the spraying and disinfection efficiency of the device. Simultaneously, the rotation of the first screw 8 drives the fixed drive gear 14 to rotate. The rotating drive gear 14 drives the meshing driven gear 15 to rotate, which in turn drives the second rotating shaft 16 to rotate, and also drives the third rotating wheel 17 to rotate. The rotating third rotating wheel 17 drives the fourth rotating wheel 18 to rotate via a belt, which in turn drives the second screw 19 to rotate. The rotating second screw 19 drives the second moving seat 20 to move up and down within the disinfection chamber 1, simultaneously causing the spray head 10 to move up and down, so that the ultraviolet lamp 21 moves synchronously with the spray head 10, irradiating the surface of the items (or the liquid can be sprayed first and left to stand for a period of time before the ultraviolet light is turned on). To prevent photolysis of unevaporated disinfectant by ultraviolet radiation, after spraying and ultraviolet irradiation, blower 22 and heater 23 are started to blow hot air through hot air cover 25 onto the items to sterilize the surface of the items at high temperature. Throughout the process, exhaust fan 29 works continuously to extract the air from the disinfection chamber 1. After being purified by the filter cotton plate and activated carbon plate in filter box 28, the air is discharged from the exhaust pipe to prevent harmful gases from leaking out. After the disinfection cycle is completed, controller 32 issues a prompt to open the sealed door 31 and take out the disinfected and dried items.
