Description

Technical Field

[0001] This application relates to the field of air purification and disinfection technology, specifically a plasma disinfection device. Background Technology

[0002] Plasma disinfection can disinfect air through the principles of air filtration, purification, and sterilization. It is an effective disinfection method. Plasma disinfection equipment can deliver clean air to the room to provide a safe air environment.

[0003] An existing patent (publication number: CN218652593U) discloses a plasma disinfection device, belonging to the field of air purification and disinfection technology. It includes a housing and a control panel. The control panel is located on one side of the housing. A motor is located at the top of the housing, and a rotating shaft is fixedly connected to the motor's output end. Blades are distributed in a circle on the rotating shaft. A fan and a reaction chamber are located at the bottom of the housing. A fan shroud is fixedly connected to the fan, which communicates with one side of the housing. A delivery pipe connects the fan and the reaction chamber. A plasma generator is fixedly connected to the reaction chamber. A connecting pipe is connected to the top of the reaction chamber, with the top end of the connecting pipe close to the bottom end of the rotating shaft. The housing has an installation slot for attaching an activated carbon plate. Square holes are provided on both the outer shell and inner wall of the housing. The motor is started via the control panel, driving the blades to rotate. The fan draws air into the plasma generator for filtration and disinfection. The disinfected air is drawn through the connecting pipe into the rotating blades and diffuses along the blade surface to be discharged from all sides of the housing, accelerating the exhaust speed and improving coverage efficiency, thus saving time.

[0004] While the device described in the aforementioned comparative document solves the problem that existing plasma disinfection equipment requires a certain amount of time to cover the entire room with clean air, which reduces its efficiency and wastes time when multiple spaces need air purification, it lacks a stable structure. After being moved, it is difficult for people to stabilize the device's position. Furthermore, in hospitals with high pedestrian traffic, pedestrians are prone to colliding with the plasma disinfection equipment, which can easily cause injuries and damage. To address these issues, a new plasma disinfection device is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a plasma disinfection device that has advantages such as easy structural stabilization, thus solving the problem that the lack of a stable structure makes it difficult for people to stabilize the device after it has been moved.

[0006] To achieve the above objectives, this application provides the following technical solution: a plasma disinfection device, including a box, an air outlet shell fixedly connected to the top of the box, and a stabilizing cylinder fixedly connected to the side of the box;

[0007] An air inlet hopper is fixedly connected to the side of the housing. A fan and a sterilization box are fixedly connected to the bottom of the housing. The fan input is fixedly connected to the air inlet output, and the fan output is fixedly connected to the inside side of the sterilization box. A connecting block is fixedly connected to the inside side of the housing. A plasma generator is fixedly connected to the side of the connecting block. A connecting pipe is fixedly connected between the plasma generator and the sterilization box. A riser is fixedly connected to the top of the plasma generator. The top of the riser is inside the air outlet housing. An installation frame is fixedly connected to the front of the sterilization box. A fixing frame is snapped into the installation frame. A filter layer is installed inside the fixing frame. Multiple ultraviolet lamps are fixedly connected to the inside side of the sterilization box. A rotating shaft is tightly nested inside the top of the stabilizing cylinder via a bearing. A knob and a threaded rod are fixedly connected to the top and bottom of the rotating shaft, respectively. A threaded cylinder is threadedly connected to the surface of the threaded rod. An anti-slip plate is fixedly connected to the bottom of the threaded cylinder.

[0008] The above scheme, through the setting of a filter layer group, has multiple layers of filter media inside, which can adsorb particulate matter, odors and chemical pollutants. By setting ultraviolet lamps, ultraviolet radiation can be emitted to achieve the purpose of preliminary sterilization. Then, under the action of the plasma generator, residual organic matter and pathogens can be completely decomposed to achieve deep sterilization. By setting a knob, when it is necessary to stabilize the position of the device, people can rotate the knob to rotate the shaft and the threaded rod, which can drive the threaded cylinder to move on the surface of the threaded rod, and push the bottom of the anti-slip plate to contact the ground, which can increase the friction with the ground and prevent the equipment from sliding when moving.

[0009] Furthermore, a limiting groove is formed on the inner side of the stabilizing cylinder, and a limiting block is fixedly connected to the surface of the threaded cylinder, with the limiting block slidably connected within the limiting groove.

[0010] The above solution restricts the threaded cylinder to only vertical movement by allowing the limiting block to slide within the limiting groove, thus preventing movement failure caused by rotation.

[0011] Furthermore, the fixed frame has two movable slots inside, the mounting frame has a slot inside, and the slot has fixing holes at both the top and bottom.

[0012] The above solution allows for the storage of limit springs, toggle plates, and fixing blocks by setting up movable slots, and allows for the matching of fixing frames by setting up slots.

[0013] Furthermore, a limiting spring is fixedly connected to the inner side of the movable groove, a toggle plate is fixedly connected to the bottom end of the limiting spring, a fixing block is fixedly connected to the side of the toggle plate, and one end of the fixing block slides through the movable groove and is engaged in the fixing hole.

[0014] With the above solution, the limiting spring pushes the actuating plate, which can make the fixing block lock into the fixing hole, so that the filter layer can be fixed or released without tools, improving the convenience of maintenance.

[0015] Furthermore, a rotary motor is fixedly connected to the top of the air outlet casing. The output end of the rotary motor rotates through the top of the air outlet casing and is fixedly connected to a rotating rod. Blades are fixedly connected to the surface of the rotating rod, and the bottom end of the blades is inside the vertical pipe.

[0016] The above scheme, by setting up a rotary motor, can make the rotating rod and blades rotate, which can accelerate the flow of gas out of the riser and expand the air outlet coverage area through centrifugal force.

[0017] Furthermore, a filter plate is slidably connected to the top of the air inlet hopper, and multiple air outlet holes are opened on the surface of the air outlet shell, with a mesh plate slidably connected to the top of the air outlet holes.

[0018] The above solution, by setting up a filter plate, can prevent impurities from flowing into the equipment, and by setting up a mesh plate, can prevent foreign objects from entering the air outlet casing, while also ensuring even airflow.

[0019] Furthermore, a door is movably connected to the front of the box.

[0020] The above solution, by setting up a door, makes it easier for people to inspect and maintain the internal components.

[0021] Furthermore, a push handle is fixedly connected to the side of the air outlet shell, and wheels are fixedly connected to the four corners of the bottom of the box.

[0022] The above solution, by setting up a push handle and wheels, enables the equipment to move flexibly and is suitable for switching between multiple scenarios such as hospitals and laboratories.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] This plasma disinfection equipment features a filter layer assembly with multiple layers of filter media to adsorb particulate matter, odors, and chemical pollutants. Ultraviolet lamps emit ultraviolet radiation for initial sterilization. Then, under the action of the plasma generator, residual organic matter and pathogens are thoroughly decomposed for deep sterilization. A knob allows for stabilization of the device; rotating the knob rotates the shaft and threaded rod, moving the threaded cylinder along the rod's surface and pushing the bottom of the anti-slip plate to contact the ground, increasing friction and preventing slippage during movement.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] Please see Figure 1 , Figure 3 and 6 The plasma disinfection device in this embodiment includes a box 1, an air outlet shell 2 fixedly connected to the top of the box 1, and a stabilizing cylinder 4 fixedly connected to the side of the box 1.

[0041] An air inlet 101 is fixedly connected to the side of the housing 1. A fan 102 and a sterilization and cleaning box 103 are fixedly connected to the bottom of the interior of the housing 1.

Multiple ultraviolet lamps 107 are fixedly connected to the inner side of the impurity removal and sterilization box 103. A rotating shaft 401 is tightly nested inside the top of the stabilizing cylinder 4 via a bearing. A knob 402 and a threaded rod 403 are fixedly connected to the top and bottom of the rotating shaft 401, respectively. A threaded cylinder is threadedly connected to the surface of the threaded rod 403. 404, the bottom end of the threaded cylinder 404 is fixedly connected to an anti-slip plate 405. A filter layer group 301, containing multiple layers of filter media, adsorbs particulate matter, odors, and chemical pollutants.

Then, under the action of the plasma generator 105, residual organic matter and pathogens are thoroughly decomposed for deep sterilization. A knob 402 allows for stabilization of the device; rotating the knob 402 allows the shaft 40 to rotate. Rotating the threaded rod 403 causes the threaded cylinder 404 to move on the surface of the threaded rod 403, which in turn pushes the bottom of the anti-slip plate 405 to contact the ground, increasing the friction with the ground and preventing the equipment from sliding during movement. A limit groove 406 is provided on the inner side of the stabilizing cylinder 404, and a limit block 407 is fixedly connected to the surface of the threaded cylinder 404.

One end of the fixing block 304 slides through the movable slot 305 and is locked in the fixing hole 106. By pushing the actuating plate 303 with the limiting spring 302, the fixing block 304 can be locked in the fixing hole 106.

A push handle 205 is fixedly connected to the side of the air outlet shell 2. Wheels 5 are fixedly connected to the four corners of the bottom of the box 1. By setting the push handle 205 and the wheels 5, the equipment can be moved flexibly and is suitable for switching between multiple scenarios such as hospitals and laboratories.

[0044] In this embodiment, the filter layer assembly 301, containing multiple layers of filter media, adsorbs particulate matter, odors, and chemical pollutants. The ultraviolet lamp 107 emits ultraviolet radiation for initial sterilization. Then, under the action of the plasma generator 105, residual organic matter and pathogens are thoroughly decomposed for deep sterilization. The knob 402 allows for stabilization of the device; rotating it rotates the shaft 401 and threaded rod 403, moving the threaded cylinder 404 on the surface of the threaded rod 403 and pushing the bottom of the anti-slip plate 405 to contact the ground, increasing friction and preventing slippage. The limit spring 302 pushes the actuating plate 303, engaging the fixing block 304 in the fixing hole 106, allowing the filter layer assembly 301 to be fixed or released without tools, improving maintenance convenience.

[0045] The working principle of the above embodiment is as follows: When in use, the fan 102 runs, drawing outside air into the purification and sterilization box 103. Then, under the action of the filter layer group 301, it can adsorb particulate matter, odors and chemical pollutants. Under the action of the ultraviolet lamp 107, it can emit ultraviolet radiation to achieve the purpose of preliminary sterilization.
