[0002] In modern life, where health and hygiene are highly valued, home disinfection has become an important line of defense for protecting the health of family members.

[0003] When existing pulsed ultraviolet sterilizers disinfect the air for a long time, the micro dust in the air will be adsorbed on the tube wall of the pulsed ultraviolet lamp, which will affect the amount of ultraviolet rays emitted and reduce the disinfection intensity and efficiency.

[0004] An existing patent (publication number: CN214148258U) discloses an ultraviolet disinfection module for a mobile air sterilizer with a self-cleaning function. It uses a pulsed ultraviolet lamp to emit ultraviolet light to disinfect the air passing through it. During the process, an ultraviolet sensor monitors the ultraviolet intensity value, and the controller controls the lamp cleaning component to work according to the ultraviolet intensity value to clean the surface of the pulsed ultraviolet lamp.

[0005] Existing patents offer solutions to the aforementioned problems, but their filtration effects are poor. In actual use, the lack of an effective filtration structure results in the inability to effectively filter out particulate impurities in the air. This not only leads to poor air disinfection and purification but also causes impurities to adhere to the surface of the pulsed ultraviolet lamp tube, affecting the amount of ultraviolet light emitted and creating a vicious cycle of efficiency decay. This severely impacts the air purification effect and reduces the practicality of the device.

[0006] Therefore, a household pulsed ultraviolet disinfection machine is proposed. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A household pulsed ultraviolet sterilizer includes a housing 1. A filter assembly 2 is fixedly connected to the top inside the housing 1, and a sterilization assembly 3 is fixedly connected to the bottom inside the housing 1. The sterilization assembly 3 includes a fixed frame 301. Threaded rods 302 are rotatably connected to both sides of the inner wall of the fixed frame 301, and a plurality of pulsed ultraviolet lamps 303 are fixedly connected to the bottom inside the fixed frame 301.

[0029] The filter assembly 2 includes a filter box 201, an exhaust plate 202 is provided on the top of the filter box 201, and movable blocks 203 are fixedly connected to both sides of the filter box 201. A fan 204 is fixedly connected to the top of the exhaust plate 202, and a cross-shaped air pipe 205 is fixedly connected to the other end of the fan 204. The four corners of the cross-shaped air pipe 205 extend to the four corners of the housing 1 and are fixedly connected to an air intake plate 206. A filter screen 207 is fixedly connected inside the air intake plate 206.

[0030] In this embodiment: the fan 204 generates suction, drawing outside air through the intake plate 206 and cross-shaped vent pipe 205 into the exhaust plate 202. Finally, the air is evenly sprayed into the filter box 201 through the exhaust plate 202. Simultaneously, the intake plate 206 and filter screen 207 increase the intake range and filter larger impurities in the air, preventing clogging of the pipes and achieving initial air filtration, thus improving the filtration effect. Then, the filter box 201 performs secondary filtration, ensuring the cleanliness of the air inside the housing 1 and preventing impurities from adhering to the surface of the pulsed ultraviolet lamp tube 303, reducing the frequency of cleaning. The efficiency ensures the air purification effect and improves the ease of use of the device. Then, under the action of the pulse ultraviolet lamp 303, the air can be disinfected. After a period of use, under the action of the hydraulic cylinder 308, the rubber cleaning plate 307 can be smoothly raised and lowered, so that the rubber cleaning plate 307 contacts the pulse ultraviolet lamp 303. At the same time, the rotating motor 305 drives the threaded rod 302 to rotate, which drives the connecting plate 306 to move smoothly, and simultaneously pushes the rubber cleaning plate 307 to move on the surface of the pulse ultraviolet lamp 303, which can scrape off the impurities attached to the surface, ensuring the disinfection effect of the pulse ultraviolet lamp 303 and improving the ease of use of the disinfection component 3.

[0031] Specifically, such as Figure 4 As shown, the surfaces of the two threaded rods 302 are threaded with sliders 304, and a rotating motor 305 is fixedly connected to the rear side of the threaded rods 302. A connecting plate 306 is fixedly connected between the opposite sides of the two sliders 304. A rubber cleaning plate 307 is movably connected to the bottom of the connecting plate 306, and hydraulic cylinders 308 are fixedly connected to both sides of the top of the rubber cleaning plate 307.

[0032] Specifically, such as Figure 4 As shown, both sides of the inner wall of the fixed frame 301 are provided with slide grooves 4 for use with the slider 304, and the threaded rod 302 is located inside the slide groove 4.

[0033] Specifically, such as Figure 4 As shown, both sliders 304 have threaded holes 5 inside for use with threaded rods 302, and the surface of the threaded rods 302 is in contact with the inner wall of the threaded holes 5.

[0034] In this embodiment: by using the slider 304 in conjunction with the groove 4, the threaded rod 302 can drive the slider 304 to move smoothly under the restriction of the groove 4, and simultaneously drive the connecting plate 306 and the rubber cleaning plate 307 to move, thereby cleaning the pulse ultraviolet lamp tube 303, ensuring the disinfection effect of the pulse ultraviolet lamp tube 303, and improving the ease of use of the disinfection component 3.

[0035] Specifically, such as Figure 5 As shown, the filter box 201 has three filter plates 6 inside, and the filtration accuracy of the filter plates 6 increases sequentially from top to bottom.

[0036] Specifically, such as Figure 3 As shown, the top of both sides of the inner wall of the box 1 is provided with a moving groove 7 for use with the moving block 203, and a positioning plate 8 is fixedly connected inside the moving groove 7. The front side of the two positioning plates 8 is rotatably connected with a buckle block 9, and the moving block 203 is slidably connected to the surface of the positioning plate 8.

[0037] In this embodiment: the use of three filter plates 6 allows air to flow through them sequentially, enabling multi-stage filtration to ensure the cleanliness of the air inside the housing 1, preventing impurities from adhering to the surface of the pulse ultraviolet lamp tube 303, reducing cleaning frequency, and improving air purification efficiency. Then, the use of the moving block 203 in conjunction with the moving groove 7 allows the moving block 203 to move smoothly within the moving groove 7 under the restriction of the positioning plate 8. At the same time, rotating the locking block 9 can release the fixed state of the moving block 203, allowing the filter box 201 to be pulled out for cleaning impurities, and can also lock the moving block 203, making the filter box 201 more firmly connected to the housing 1, preventing shaking and falling during use, ensuring the filtration effect of the filter assembly 2, and improving the ease of use of the filter assembly 2.

[0038] Specifically, such as Figure 3 As shown, a storage battery 10 is fixedly connected to the rear side of the bottom of the inner wall of the box 1, and the storage battery 10 is electrically connected to the disinfection component 3 and the filter component 2. A controller 11 is fixedly connected to the top of the box 1, and the controller 11 is electrically connected to the storage battery 10, the disinfection component 3 and the filter component 2.

[0039] Specifically, such as Figure 3 As shown, steering wheels 12 are fixedly connected to the four corners of the bottom of the box 1, and a baffle plate 13 is movably connected to the rear side of the box 1. An exhaust hole 14 is provided at the bottom of the front side of the box 1, and a louver 15 is fixedly connected inside the exhaust hole 14.

[0040] In this embodiment: the steering wheel 12 allows the operator to move the device smoothly and adjust its position flexibly according to the actual situation, facilitating air purification in the home. The baffle 13 can be quickly opened, connecting the housing 1 to the outside world for easier maintenance and repair. The exhaust vent 14, in conjunction with the louvers 15, ensures the smooth discharge of purified air while preventing external impurities from entering the housing 1, improving the device's usability. The controller 11 precisely regulates the continuous and stable power supply of the battery 10 to the disinfection component 3 and the filter component 2, flexibly controlling their operation. This not only guides airflow for filtration but also cleans the pulse ultraviolet lamp 303, ensuring its disinfection effect and enhancing the device's practicality.

[0041] Working Principle: When disinfecting and purifying indoor air, the operator first moves the device to a suitable position using the steering wheels 12. Then, the operator uses the controller 11 to control the battery 10 to provide stable power to the disinfection component 3 and the filter component 2, and sets the operating parameters for the disinfection component 3 and the filter component 2. Subsequently, the fan 204 is activated to generate suction, causing air to pass through the intake plate 206 and filter screen 207 for initial filtration of large particles. The air then enters the filter box 201 through the cross-shaped air duct 205 and exhaust plate 202. Subsequently, under the action of the three filter plates 6, the air undergoes multi-stage filtration, ensuring the cleanliness of the air inside the housing 1 and preventing impurities from adhering to the surface of the pulse ultraviolet lamp tube 303, reducing the frequency of cleaning. During the air filtration process, the pulse ultraviolet lamp tube 303 is activated for efficient air sterilization. After air purification is completed, the air passes through the filter box 201. The louvers 15 smoothly discharge air, completing the air purification process. After the equipment has been running for a period of time, the hydraulic cylinder 308 is activated, driving the rubber cleaning plate 307 to precisely rise and fall, so that the rubber cleaning plate 307 contacts the pulse ultraviolet lamp 303. At the same time, the rotating motor 305 is activated to drive the threaded rod 302 to rotate, driving the slider 304 to move along the threaded rod 302, and simultaneously driving the rubber cleaning plate 307 to move on the surface of the pulse ultraviolet lamp 303, which can quickly scrape off the impurities attached to the surface of the pulse ultraviolet lamp 303, ensuring the disinfection effect of the pulse ultraviolet lamp 303. After disinfection is completed, the locking block 9 is rotated to release the locking state of the moving block 203, and the filter box 201 is smoothly pulled out, completing the cleaning and maintenance of the filter plate 6. After cleaning, the filter box 201 is reset and the locking block 9 is rotated in the opposite direction to fix the filter box 201, restoring the filtration effect of the device.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
