[0022] The following describes the embodiments of the present application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.
[0023] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. The illustrations only show the components related to the present application rather than being drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.
[0024] The specific implementation methods of the present application will be further described below in conjunction with the accompanying drawings.
[0025] Example:
[0026] The embodiment of the present application discloses a high-efficiency fresh air fan with automatically replaceable filter materials, comprising a casing 1 and a fan 2. An air inlet 11 is provided on one side of the casing 1, and an air chamber 3 is provided in the casing 1. The fan 2 is fixed in the air chamber 3, and the air chamber 3 is connected to the air supply port on the outer casing. The fan 2 sucks outside air into the air chamber 3 and discharges it from the air supply port through the air chamber 3. A rotatable first rotating shaft 4 and a second rotating shaft 5 are respectively provided on both sides of the air supply port in the casing 1. A filter material conveying shaft 6 and a filter material recovery shaft 7 are provided in the casing 1. A driver 8 is provided on the filter material recovery shaft 7 for rolling up the filter material, wherein the rolled filter material is placed on the filter material conveying shaft 6 and spread through the first rotating shaft 4, the air supply port, the second rotating shaft 5, and the filter material recovery shaft 7.
[0027] Casing 1 adopts sheet metal, hard texture, and adopts rectangular structure, which is convenient for transportation and handling. In other alternative implementation cases, the first rotating shaft 4 and the second rotating shaft 5 can be roller devices of the same principle. About filter material, in this scheme, it is a band-shaped roll storage, which can be a roll of non-woven fabrics, mesh cloth, gauze, air filter cotton (various filter levels) etc. It can be put into the filter material conveying shaft 6, and the filter material conveying shaft 6 does not need to rotate. Pull out one end of the rolled filter material, traction passes through the first rotating shaft 4, air supply port, the second rotating shaft 5, and the filter material recovery shaft 7, and the filter material recovery shaft 7 is by rotating the rolled filter material.
[0028] Working description: The air is transferred by the power of the fan 2, and the air is sent out from the air outlet. Since there is a belt-shaped filter material at the air outlet, it can filter the air. After working for a long time, the filter material at the air outlet will have a lot of dust and need to be cleaned. The driver 8 drives the filter material recovery shaft 7 to rotate to rewind the filter material, so that the filter material that absorbs dust is retracted and moved, and the clean filter material takes over the position of the air outlet to continue working, so that it can work for a long time.
[0029] In this solution, the air chamber 3 includes three side panels 31 and a mesh panel 32, which are surrounded by a rectangular frame, and the mesh panel 32 is located at the air outlet and on the inner side of the filter material. A detachable panel 12 is provided on the housing 1 at the air outlet, and the panel 12 is located on the outer side of the filter material. The panel 12 and the mesh panel 32 form a gap channel for guiding the filter material to move.
[0030] In such a structure, the filter material is also limited by the mesh plate 32 and the panel 12, and can be effectively laid flat at the air outlet.
[0031] In order to make the structure more stable and reliable, the ends of the filter material delivery shaft 6 and the filter material recovery shaft 7 are connected with a crossbeam 9, the filter material delivery shaft 6 is fixed on the crossbeam 9 and does not move, and the filter material recovery shaft 7 is passed through the crossbeam 9 and rotates. The crossbeam 9 can be used to limit the filter material to prevent the filter material from shaking and position deviation. The crossbeam 9 can be fixed on the partition 10 by screws, and the crossbeam 9 can be disassembled, which is also convenient for replacing the entire roll of filter material.
[0032] The housing 1 is provided with an interlayer plate 13 for supporting the filter material, and the interlayer plate 13 and the housing 1 form an interlayer chamber 14 for installing the driver 8. The interlayer plate 13 can isolate the installation space of the driver 8 so that the filter material will not be contaminated during the maintenance process.
[0033] Finally, the air inlet 11 of the casing 1 is a mounting surface 16, and the casing 1 is provided with a mounting edge 15 on the side of the mounting surface 16. The product of this scheme can be applied in a home environment, such as on a door or a wall. A mounting groove is provided on the door, and the product is embedded and fixed therein, and then the space inside and outside the door is isolated, and by starting the fan 2, the air outside the door is filtered through the filter material and goes out from the air outlet, and the outdoor air is filtered and sent into the room. The driver 8 is a micro motor, which can be driven regularly, and then the filtering part of the filter material is replaced, and the dusty part is rolled up, and the clean part is sent back in. The above embodiments are only illustrative of the principles and effects of the present application, and are not used to limit the present application. Anyone familiar with this technology can modify or change the above embodiments without violating the spirit and scope of the present application. Therefore: all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the scope of protection of the present application.
