[0030] like Figures 1 to 10As shown, an indoor air microbial purification device involved in the present invention comprises a box body 1, an exhaust fan 2 and a filter element 3 installed in the box body 1, a roller 19 is provided at the bottom of the box body 1 to facilitate the movement of the device, an air inlet 11 and an air outlet 12 are formed on the side wall of the box body 1, the box body 1 is provided with a filter chamber 13 connected to the air inlet 11, a receiving chamber 14 for storing unused filter elements 3 and a collection chamber 15 for storing discarded filter elements 3, the filter chamber 13 is provided with a plurality of filter elements 3 arranged in a vertical direction; the receiving chamber 14 and the collection chamber 15 are respectively located on both sides of the filter chamber 13; a first through slot 131 for the filter element 3 to pass through is provided between the receiving chamber 14 and the filter chamber 13, and the filter chamber 13 is provided with a plurality of filter elements 3 arranged in a vertical direction; the receiving chamber 14 and the collection chamber 15 are respectively located on both sides of the filter chamber 13; a first through slot 131 for the filter element 3 to pass through is provided between the receiving chamber 14 and the filter chamber 13 A second through groove 132 is formed between the collecting chamber 15 for the filter element 3 to pass through; the first through groove 131 is aligned with the filter element 3 in the lowest layer in the filter chamber 13 on the same horizontal plane, and the second through groove 132 is aligned with the filter element 3 in the top layer in the filter chamber 13 on the same horizontal plane; the accommodating chamber 14 is provided with a first moving component 4 for pushing the filter element 3 in the accommodating chamber 14 into the filter chamber 13, the filter chamber 13 is provided with a second moving component 5 for pushing the filter element 3 in the filter chamber 13 into the collecting chamber 15, and the filter chamber 13 is also provided with a lifting component 6 for pushing the filter element 3 upward; the box body 1 is also provided with an installation chamber 16 for installing the exhaust fan 2, and the bottom of the installation chamber 16 is connected to the bottom of the filter chamber 13. By providing a accommodating chamber 14 for storing unused filter cartridges 3 and a collecting chamber 15 for collecting used discarded filter cartridges 3 in the box body 1, when the filter cartridge 3 needs to be replaced after the device has been used for a period of time, the top filter cartridge 3 in the filter chamber 13 can be directly pulled into the collecting chamber 15 by the second moving component 5, and then the lifting component 6 can lift the remaining filter cartridges 3 in the filter chamber 13 upward, and finally the filter cartridge 3 in the accommodating chamber 14 can be moved into the filter chamber 13 by the first moving component 4. The whole operation process is very convenient, there is no need to disassemble the device, and the number of filter cartridges 3 to be replaced can be selected according to actual conditions.In this embodiment, to enhance the fluidity of the air in the filter chamber 13, the filter element 3 includes a filter portion 31 and a frame 32. The filter portion 31 is an H14-grade HEPA filter material that can mechanically capture and intercept microorganisms and electrostatically adsorb nano-scale viruses. The frame 32 is higher than the filter portion 31, and the filter portion 31 is located at the middle height of the frame 32. The frame 32 can provide a larger gap between the filter portions 31, thereby improving the fluidity of the air in the filter chamber 13. In addition, the frame 32 is sealed against the inner wall of the filter chamber 13. The friction between the frame 32 and the filter chamber 13 is greater than the weight of the filter element 3, which can prevent the filter element 3 from sliding down in the filter chamber 13 when the filter element 3 is replaced. The frame 32 is slidably fitted with the inner wall of the accommodating chamber 14 and the inner wall of the collection chamber 15. That is, the friction between the frame 32 and the inner wall of the accommodating chamber 14 and the inner wall of the collection chamber 15 is less than the weight of the filter element 3, which can cause the filter element 3 to slide down automatically.

[0031] In this embodiment, a support plate 141 for supporting the filter element 3 is formed on the inner wall of the accommodating chamber 14, and the upper surface of the support plate 141 is flush with the first through groove 131; the first movable component 4 includes a first push-pull plate 41 and a first pull rod 42 connected to both ends of the first push-pull plate 41, and first sliders 411 are formed at both ends of the first push-pull plate 41, and the first pull rod 42 is connected to the first slider 411. A first slide groove cooperating with the first slider 411 is formed on the inner wall of the accommodating chamber 14, and a first accommodating groove for accommodating the first push-pull plate 41 is formed on the side wall of the accommodating chamber 14 away from the filter chamber 13. When the first movable component 4 is not needed, the first push-pull plate 41 is hidden in the first accommodating groove to avoid interference with the filter element 3. In addition, a through hole for the first pull rod 42 to pass through is formed on the side wall of the box body 1. The two first pull rods 42 pass through the side wall of the box body 1 and form a first handle 421 at the end. When the filter element 3 in the accommodating chamber 14 needs to be pulled into the filter chamber 13 , the first handle 421 only needs to be pulled to move the first push-pull plate 41 toward the filter chamber, thereby pushing the filter element 3 in the accommodating chamber 14 into the filter chamber 13 .

[0032] In this embodiment, in order to prevent the filter element 3 above the accommodating chamber 14 from sliding down directly when the first push-pull plate 41 has not yet reset after pushing the filter element 3 to the filter chamber 13, thereby affecting the reset of the first push-pull plate 41, a support block 142 is movably provided on the inner wall of the accommodating chamber 14, and a movable groove for mounting the support block 142 is formed on the inner wall of the accommodating chamber 14, and a return spring 143 is also provided in the movable groove, one end of the return spring 143 is fixedly connected to the support block 142, and the other end is fixedly connected to the movable groove; a guide slope 1421 is formed on the end of the support block 142 close to the filter chamber 13, which is slidably matched with the first push-pull plate 41; the height of the upper surface of the support block 142 is equal to or greater than the height of the first push-pull plate 41. When the first push-pull plate 41 is not moving, the two ends of the first push-pull plate 41 will be squeezed on the side walls of the support plate 141, squeezing the support block 142 into the movable groove. In the process of pushing the filter element 3 by the first push-pull plate 41, when the first push-pull plate 41 is away from the support block 142, the support block 142 can be pushed outward for a distance under the action of the reset spring 143, so that the upper filter element 3 can be lifted up by the support block 142 to avoid further sliding. When the first push-pull plate 41 is in the process of resetting, the first push-pull plate 41 can gradually squeeze the support block 142 into the movable groove through the guide slope 1421 of the support block 142. When the first push-pull plate 41 is fully reset, the upper filter element 3 can slide down and fall on the support plate 141.

[0033] In this embodiment, the second movable assembly 5 includes a second push-pull plate 51 and a second pull rod 52 connected to both ends of the second push-pull plate 51. Second sliders 511 are formed at both ends of the second push-pull plate 51. The second pull rod 52 is connected to the second slider 511. A second slide groove that cooperates with the second slider 511 is formed on the inner wall of the filter chamber 13. The two second pull rods 52 pass through the side wall of the box body 1 and form a second handle 521 at the end. A second receiving groove for accommodating the second push-pull plate 51 is formed on a side wall of the filter chamber 13 away from the collection chamber 15. When the second movable component 5 is not needed, the second push-pull plate 51 is hidden in the second receiving groove to avoid interference with the filter element 3. A through hole for the second pull rod 52 to pass through is also formed on the side wall of the box body 1. When the second movable component 5 is used to move the filter element 3 to the collection chamber 15, it is only necessary to pull the second pull rod 52 through the second handle 521 to move the second push-pull plate 51 toward the collection chamber 15. Under the action of the second push-pull plate 51, the filter element 3 can be pushed into the collection chamber 15.

[0034] In this embodiment, the lifting assembly 6 includes a support frame 61 and a lifting cylinder 62. A lifting plate 611 is provided below the support frame 61. A connecting rod 612 is provided between the lifting plate 611 and the support frame 61. The piston rod of the lifting cylinder 62 is fixedly connected to the bottom of the lifting plate 611. The support frame 61 can contact the frame 32 of the filter element 3. The lifting cylinder 62 can precisely control the lifting distance of the support frame 61. Specifically, each lifting distance is equal to the height of the frame 32.

[0035] In this embodiment, in order to further disinfect and sterilize the filtered and purified air, a disinfection chamber 17 for storing disinfectant liquid is further provided in the box body 1. The disinfection chamber 17 is located on one side of the installation chamber 16, and the disinfectant liquid can be a hydrogen peroxide solution with a concentration of 3%-8%; the disinfection chamber 17 includes an air inlet chamber 171 and an exhaust chamber 172, and a partition is provided between the air inlet chamber 171 and the exhaust chamber 172, and the bottom of the air inlet chamber 171 is connected to the bottom of the exhaust chamber 172; the top of the installation chamber 16 is connected to the top of the air inlet chamber 171; an air outlet chamber 18 is also provided in the box body 1, and the air outlet chamber 18 is located above the disinfection chamber 17 and the installation chamber 16, and the top of the exhaust chamber 172 is connected to the air outlet chamber 18; the air outlet 12 is connected to the air outlet chamber 18. Under the action of the exhaust fan 2, the filtered and purified air is drawn from the filter chamber into the disinfection chamber 17 for disinfection and sterilization, and then enters the air outlet chamber 18 and is discharged from the air outlet 12. In addition, an air freshener can be placed in the air outlet chamber 18 to cover up and reduce the irritating smell of the disinfectant liquid.

[0036] In this embodiment, in order to make it easier for air to enter the disinfectant liquid, an airflow enhancement mechanism 7 is further provided in the air inlet chamber 171; the airflow enhancement mechanism 7 includes a fixed box 71, an ascending pipe 72 connected to the bottom of the fixed box 71, and a descending pipe 73, the end of the descending pipe 73 is also connected to a water pump 74, the bottom of the ascending pipe 72 is in the disinfectant liquid, a fixed mounting frame is provided on the outer wall of the fixed box 71, and the fixed mounting frame is connected to the inner wall of the air inlet chamber 171; the descending pipe 73 has a contraction section 731, the inner diameter of the contraction section 731 gradually decreases from top to bottom, and a plurality of air inlet holes 732 are formed on the contraction section 731, and the air inlet holes 732 are arranged obliquely; the other end of the water pump 74 is connected to an exhaust pipe 75 extending to the exhaust chamber 172, and the outlet of the exhaust pipe 75 is below the liquid level of the disinfectant liquid and within 3-8 cm from the liquid level, so that the gas can more easily break through the liquid level. When the water pump 74 is working, it can draw the disinfectant liquid from the ascending pipe 72 into the fixed box 71 and flow it into the descending pipe 73. When the disinfectant liquid passes through the contraction section 731 of the descending pipe 73, the flow rate increases, and the pressure inside the descending pipe 73 is lower than the external pressure, thereby drawing the air in the air intake chamber into the descending pipe 73 and following the disinfectant liquid into the exhaust chamber 172. In this process, the air comes into contact with the disinfectant liquid, thereby disinfecting and sterilizing the air.

[0037] In this embodiment, because the air in the air inlet chamber 171 cannot be completely drawn into the descending duct 73, a vent 161 is formed between the installation chamber 16 and the air inlet chamber 171; the height of the vent 161 is lower than the height of the air inlet hole 732. Air that does not enter the airflow enhancement mechanism 7 is recovered through the vent 161 into the installation chamber 16 and then fed into the disinfection chamber 17, thereby improving the efficiency of purification and sterilization.

[0038] In this embodiment, an empty chamber is further provided in the box body 1 for installing electronic control components such as a controller. The empty chamber can be provided on the other side of the installation chamber 16. Box covers are independently provided on the tops of these chambers, which can be opened to repair the internal structure.

[0039] The method of using the present invention is as follows: first, the outside air is drawn into the filter chamber 13 from the air inlet 11 by the exhaust fan 2, and then enters the installation chamber 16 after being filtered by the filter element 3 of the filter chamber 13, and then enters the air inlet chamber 171 of the disinfection chamber 17. Under the action of the water pump 74, the air is further drawn into the downpipe 73, mixed with the disinfectant liquid, and then enters the air outlet chamber 18 from the exhaust chamber 172, and finally discharged from the air outlet 12. 1 shows that the air drawn into the descending pipe 73 can re-enter the installation chamber 16 and be recirculated to the air intake chamber; when replacing the filter element 3, the top filter element 3 in the filter chamber 13 is first moved to the collection chamber 15 by the second moving component 5, and then the remaining filter elements 3 in the filter chamber 13 are lifted up one grid by the lifting component 6, and then the lifting component 6 is reset, and then the filter element 3 in the accommodating chamber 14 is moved to the filter chamber 13 by the first moving component 4.
