Description

Technical Field

[0001] This utility model relates to the field of fan technology, and in particular to a fan with air purification function. Background Technology

[0002] Fans, as common electrical appliances, are widely used in daily life and work, primarily to accelerate air circulation and bring a cooling sensation. However, with the improvement of people's living standards and increasing attention to air quality, fans with only a blowing function can no longer meet people's growing needs. In modern living environments, the air contains various pollutants, such as dust, pollen, smoke, bacteria, and viruses. These pollutants not only affect indoor air quality but may also harm human health, causing respiratory diseases, allergic reactions, and other problems. Air quality issues are particularly prominent in poorly ventilated spaces or areas with frequent smog.

[0003] Existing air purification devices, such as air purifiers, can effectively remove pollutants from the air, but they are usually standalone devices that take up a lot of space and have relatively limited functions. They can only be placed in one location to purify the air. Products that combine fans with air purification functions are relatively rare on the market. Therefore, a fan with air purification function is proposed. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The purpose of this invention is to provide a fan with an air purification function, which solves the problem mentioned in the background art that existing air purification devices, such as air purifiers, although they can effectively remove pollutants from the air, are usually independent devices that occupy a lot of space and have relatively simple functions. They can only be placed in a static position to purify the air. Products that combine a fan with an air purification function are still relatively rare in the market.

The purification mechanism includes a support rod inserted into the limiting port, a coarse filter installed on the upper part of the support rod, a fine filter installed in the middle of the support rod, and an activated carbon layer installed on the lower part of the support rod. The support mechanism includes a threaded rod threadedly connected to the surface of the extension blocks, a rotating shaft rotatably connected to the bottom of the threaded rod, and a powerful suction cup installed at the bottom of the rotating shaft.

[0008] As a further embodiment of this utility model, the upper surface of the powerful suction cup is provided with a vent, and a sealing plug is inserted into the vent. The vent serves to relieve pressure.

[0009] As a further embodiment of this utility model, positioning blocks are fixedly connected to both sides of the upper surface of the lower connecting shell, and connecting rods are inserted into the interior of the positioning blocks. The connecting rods serve to connect the upper and lower shells.

[0010] As a further embodiment of this utility model, positioning holes are provided on the surfaces of both the positioning block and the connecting rod, and pins are inserted into the interior of the positioning holes. The pins serve to limit the movement of the connecting rod.

[0011] As a further embodiment of this utility model, a support spring is sleeved on the surface of the pin, and a handle is fixedly connected to one side of the pin. The handle serves to pull the pin.

[0012] As a further embodiment of this utility model, one side of the support spring is fixedly connected to the surface of the positioning block, and the other side of the support spring is fixedly connected to the surface of the handle. The support spring provides a reverse force for the pin.

[0014] (III) Beneficial Effects

[0015] This utility model provides a fan with air purification function, which has the following beneficial effects:

[0016] 1. This fan with air purification function, through its purification mechanism, features support rods installed inside the upper and lower connecting shells. The surfaces of these support rods are respectively equipped with a coarse filter, a fine filter, and an activated carbon layer. A suction fan installed at the top of the upper connecting shell draws outside air into the lower connecting shell, where the coarse filter, fine filter, and activated carbon layer filter impurities and adsorb harmful substances, thus achieving air purification. Furthermore, the support rods are installed using a plug-in method, facilitating the cleaning and replacement of the filters and activated carbon layer later. The structure is simple, economical, and practical.

[0017] 2. This fan with air purification function, through the setting of the support mechanism, is usually placed on the ground or table during use. The device is easily subject to external forces that may cause it to shift or fall. Therefore, four strong suction cups are set at the bottom of the lower connecting shell. Rotating the threaded rod at the top, driven by the bottom rotating shaft, causes the strong suction cups on one side of the rotating shaft to press downward, so that the device can be firmly attached to the surface of the external support structure, ensuring that it remains in a stable state during use and preventing it from shifting and falling due to external forces, thus avoiding damage to the surface of the device.

The structure is simple, economical, and practical. Extension blocks 6 are fixedly connected to all four sides of the lower surface of the lower connecting shell 1, and a support mechanism 7 is threadedly connected to the surface of the extension blocks 6. The support mechanism 7 prevents the fan from shifting and falling due to external force, thus avoiding damage to the surface of the device. A suction fan 17 is installed on the inner top of the upper connecting shell 2. Several ventilation holes are opened on the surfaces of both the upper connecting shell 2 and the lower connecting shell 1.

[0026] The support mechanism 7 includes a threaded rod 701 threaded to the surface of the extension block 6, a rotating shaft 702 rotatably connected to the bottom of the threaded rod 701, and a powerful suction cup 703 installed at the bottom of the rotating shaft 702.

[0027] The upper surface of the powerful suction cup 703 is provided with a vent 8, and a sealing plug 9 is inserted inside the vent 8. The vent 8 serves to relieve pressure.

[0028] Positioning blocks 10 are fixedly connected to both sides of the upper surface of the lower connecting shell 1. A connecting rod 11 is inserted into the inside of the positioning block 10. The connecting rod 11 serves to connect the upper and lower shells.

[0029] Positioning holes are provided on the surfaces of both the positioning block 10 and the connecting rod 11. A pin 12 is inserted into the inside of the positioning hole. The pin 12 serves to limit the position of the connecting rod 11.

[0030] A support spring 13 is sleeved on the surface of the pin 12, and a handle 14 is fixedly connected to one side of the pin 12. The handle 14 is used to pull the pin 12.

[0033] In this invention, the working steps of the device are as follows:

[0034] First step: When in use, a support rod 501 is installed inside the upper connecting shell 2 and the lower connecting shell 1. The surface of the support rod 501 is respectively provided with a coarse filter 502, a fine filter 503 and an activated carbon layer 504. The suction fan 17 installed at the top of the upper connecting shell 2 draws outside air into the lower connecting shell 1, where the coarse filter 502, the fine filter 503 and the activated carbon layer 504 respectively filter impurities and adsorb harmful substances.
