[0025] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0026] In the description of the present invention, it should be understood that descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0027] In the description of the present utility model, "greater than", "less than", "exceed" etc. are understood as not including the number itself, and "above", "below", "within" etc. are understood as including the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0028] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0029] See also Figure 1-6The utility model provides a technical solution: a medical clean air filter, comprising a filter housing 1 and a filter plate mounting frame 2, a filter plate fixing assembly, the filter plate fixing assembly is arranged at the front end of the filter housing 1, the filter plate fixing assembly comprises a filter plate 14, the filter plate 14 is slidably connected to the inside of the filter plate mounting frame 2, a first thread groove 16 is provided on the surface of the filter plate mounting frame 2, a second thread groove 17 is provided on the surface of the filter plate 14, the first thread groove 16 and the second thread groove 17 are connected to each other, and the inner walls of the first thread groove 16 and the second thread groove 17 are threadedly connected with a screw 4, and the surface of the screw 4 is fixedly connected with a connecting block 15.

[0030] The filter plate fixing assembly also includes a rotating shaft 8, which is rotatably connected to the surface of the filter housing 1, and a limiting plate 9 is fixedly connected to the surface of the rotating shaft 8. A limiting block 10 is fixedly connected to the surface of the filter plate mounting frame 2, and the limiting plate 9 is snap-fitted with the limiting block 10. A connecting plate 11 is fixedly connected to the surface of the filter housing 1, and a spring 12 is fixedly connected to one end of the connecting plate 11 close to the limiting plate 9. A connecting rod 13 is fixedly connected to the surface of the limiting plate 9, and an end of the spring 12 away from the connecting plate 11 is fixedly connected to the connecting rod 13.

[0031] The filter element of the filter plate 14 is wavy.

[0032] Two hinges 3 are fixedly installed at the front end of the filter housing 1 , and one end of the two hinges 3 away from the filter housing 1 is fixedly installed on the surface of the filter plate mounting frame 2 , and the filter plate mounting frame 2 is rotatably connected to the filter housing 1 through the two hinges 3 .

[0033] A fan bracket 5 is fixedly connected to the inner wall of the filter housing 1 , a driving motor 6 is fixedly connected to the surface of the fan bracket 5 , and an output end of the driving motor 6 rotates through the fan bracket 5 and is fixedly connected to a plurality of fan blades 7 .

[0034] When using the device, start the drive motor 6 to drive the fan blades 7 to rotate, promote air circulation, and facilitate filtering and purifying the air. After the filter plate 14 has been used for a period of time, a certain amount of dust will adhere to the surface of the filter plate 14, which may easily affect the filtering effect of the filter plate 14. At this time, the filter plate 14 needs to be disassembled, cleaned or replaced. First, move the limit plate 9 to make the limit plate 9 rotate around the rotating shaft 8 and separate from the limit block 10. When the limit plate 9 rotates, it drives the connecting rod 13 to rotate. The connecting rod 13 stretches the spring 12, and then the filter plate mounting frame 2 is opened to make the filter plate mounting frame 2 rotate around the filter housing 1 to separate the side of the filter plate mounting frame 2 from the filter housing 1.

[0035] Then rotate the screw 4 and the connecting block 15 to separate the screw 4 from the filter plate mounting frame 2 and the filter plate 14, and separate from the first thread groove 16 and the second thread groove 17. The setting of the connecting block 15 facilitates the disassembly of the screw 4 and improves the disassembly efficiency of the filter plate 14. Then pull the filter plate 14 toward the outside of the filter plate mounting frame 2 to separate the filter plate 14 from the filter plate mounting frame 2, so as to facilitate the disassembly of the filter plate 14.

[0036] Furthermore, by clamping the limit plate 9 and the limit block 10, and fixing the filter plate mounting frame 2 and the filter plate 14 with the screws 4, it is convenient to install and disassemble the filter plate 14. Compared with removing multiple screws, only one screw needs to be removed, and through the setting of the connecting block 15, the screw 4 can be removed without using tools such as wrenches, which facilitates the removal of the screw 4 and the removal, cleaning or replacement of the filter plate 14, thereby improving the removal efficiency of the screw 4 and reducing safety risks and maintenance costs.

[0037] By setting the spring 12, it is convenient to limit the limit plate 9 and the limit block 10, and to limit the filter plate 14, thereby improving the stability of the filter plate 14. The fixed and stable filter plate 14 can effectively prevent dust, impurities and other particulate matter from entering the ventilation system, thereby maintaining the cleanliness of the air circulation.

[0038] Working principle: When using the device, start the drive motor 6 to drive the fan blades 7 to rotate, promote air circulation, and facilitate filtering and purifying the air. After the filter plate 14 has been used for a period of time, a certain amount of dust will adhere to the surface of the filter plate 14, which may easily affect the filtering effect of the filter plate 14. At this time, the filter plate 14 needs to be disassembled, cleaned or replaced. First, move the limit plate 9 to make the limit plate 9 rotate around the rotating shaft 8 and separate from the limit block 10. When the limit plate 9 rotates, it drives the connecting rod 13 to rotate. The connecting rod 13 stretches the spring 12, and then the filter plate mounting frame 2 is opened to make the filter plate mounting frame 2 rotate around the filter housing 1, so that the side of the filter plate mounting frame 2 is separated from the filter housing 1.

[0039] Then rotate the screw 4 and the connecting block 15 to separate the screw 4 from the filter plate mounting frame 2 and the filter plate 14, and separate from the first thread groove 16 and the second thread groove 17. The setting of the connecting block 15 facilitates the disassembly of the screw 4 and improves the disassembly efficiency of the filter plate 14. Then pull the filter plate 14 toward the outside of the filter plate mounting frame 2 to separate the filter plate 14 from the filter plate mounting frame 2, so as to facilitate the disassembly of the filter plate 14.

[0040] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
