[0003] Although some formaldehyde can be absorbed by using formaldehyde-removing plants, air purifiers, activated carbon, formaldehyde-removing gel and other products, the formaldehyde removal efficiency of formaldehyde-removing plants is low, and air purifiers cannot be placed in vertically long and narrow rectangular spaces such as cabinets and wardrobes. Simply placing activated carbon at the bottom of the wardrobe can only absorb formaldehyde at the bottom of the wardrobe through passive adsorption, and the formaldehyde volatilized in the upper space of the wardrobe cannot be treated for a long time. For example, placing formaldehyde-removing gel at the bottom of the wardrobe, since formaldehyde-removing gel is usually large particles and the effective height of upward volatilization is limited, it is also impossible to remove formaldehyde in the upper part of the wardrobe. This results in the use of many formaldehyde-removing products, but the air inside the cabinet is not circulated, and the passive adsorption formaldehyde removal method is limited in effect, and formaldehyde cannot be absorbed in the short term.

[0004] Therefore, the present invention provides a fan for removing formaldehyde. Summary of the invention

[0050] Figure 1 It is a three-dimensional diagram of a fan for removing formaldehyde according to the present invention. Figure 2 It is a cross-sectional view of the formaldehyde removing fan of the present invention. Figure 3 The figure is an exploded view of the formaldehyde removing fan of the present invention. Figure 4 The figure is a working principle diagram of the fan for removing formaldehyde of the present invention. Figures 1 to 4As shown, the fan for removing formaldehyde of the present invention comprises a body 1 and a formaldehyde adsorption component 2. The body 1 comprises an air inlet 11, a fan 12 for generating an air flow, and an air outlet 14. The formaldehyde adsorption component 2 is connected above the air outlet 14. The formaldehyde adsorption component 2 comprises a filter pipe 21 having a formaldehyde adsorption medium. The air flow passes through the adsorption medium in the filter pipe 21 in the anti-gravity direction and then is emitted upward. The fan 12 comprises an impeller with a high rotation speed to provide a large suction force, and the adsorption medium is located downstream of the fan 12.

[0051] In a preferred embodiment, the formaldehyde adsorption medium is an activated carbon bag for adsorbing formaldehyde or a stacked combination of multiple activated carbon bags, but the present invention is not limited thereto.

[0052] In a preferred embodiment, an upwardly open volatilization groove 22 is provided around the filter pipeline 21, and the volatilization groove 22 is filled with volatile formaldehyde-removing gel. The volatile formaldehyde-removing gel is volatilized upward by the disturbance of the upwardly emitted air flow, but it is not limited to this.

[0053] In a preferred embodiment, the filter pipeline 21 is a circular pipe, and the opening of the volatilization groove 22 is an annular groove body surrounding the upper end of the filter pipeline 21, but it is not limited thereto.

[0054] In a preferred embodiment, it further includes: a dustproof net, which is arranged in the filter pipe 21 and is pressed to the bottom of the filter pipe 21 by the formaldehyde adsorption medium, but the present invention is not limited thereto.

[0055] In a preferred embodiment, it further comprises: a breathable cover plate 23 connected to the upper end of the formaldehyde adsorption component 2, covering the filter pipe 21 and the volatilization tank 22, and the air flow after the formaldehyde adsorption medium removes the formaldehyde is emitted upward through the breathable cover plate 23. After the volatile formaldehyde removal gel volatilizes, it passes through the breathable cover plate 23 and gradually diffuses as the air flow continues to rise, but the present invention is not limited thereto.

[0056] In a preferred embodiment, a bayonet is provided at the bottom of the formaldehyde adsorption component 2 and is detachably engaged with a bayonet slot 13 surrounding the air outlet 14 of the body 1 , but the present invention is not limited thereto.

[0057] In a preferred embodiment, external air enters the body 1 vertically upward from the air inlet 11 at the bottom of the body 1, but the present invention is not limited thereto.

[0058] The specific use of the present invention is as follows:

[0059] The body 1 of the formaldehyde-removing fan of the present invention comprises an air inlet 11, a fan 12 for generating an air flow, and an air outlet 14. The formaldehyde adsorption component 2 is connected above the air outlet 14. The formaldehyde adsorption component 2 comprises a filter pipe 21 having a formaldehyde adsorption medium. The air flow passes through the adsorption medium in the filter pipe 21 in the anti-gravity direction and then is emitted upward. The fan 12 comprises an impeller with a high rotation speed to provide a large suction force. The adsorption medium is located downstream of the fan 12. At this time, the formaldehyde-removing fan of the present invention works in the state of a formaldehyde-removing air purifier. The structure of the present invention is different from that of most of the formaldehyde removal purifiers in the prior art in that the formaldehyde removal purifiers in the prior art usually use a large-area formaldehyde removal filter mesh set vertically before the air inlet of the axial flow fan, and use the axial flow fan to draw air upward (the direction of air passing through the formaldehyde removal filter mesh is perpendicular to the direction of air passing through the axial flow fan), and the formaldehyde removal efficiency can be improved by increasing the area of ​​the formaldehyde removal filter mesh, but the volume of this structure is very large and difficult to be placed in a slender space such as a closet; while the present invention uses a formaldehyde adsorption medium set at the air outlet of the impeller, so that the direction of air flow passing through the impeller and the direction of air flow passing through the formaldehyde adsorption medium are almost on the same axis, thereby greatly reducing the volume of the machine, which is particularly beneficial for use in a narrow vertical extension space such as a closet. In addition, the formaldehyde adsorption medium in the present invention is a stacked combination of multiple activated carbon bags. The filter pipeline 21 is a circular pipe fitting, and the opening of the volatilization tank 22 is an annular tank body surrounding the upper end of the filter pipeline 21. The dust screen is arranged in the filter pipe 21 and is pressed by the formaldehyde adsorption medium to the bottom of the filter pipe 21. The bottom of the formaldehyde adsorption component 2 is provided with a bayonet, which is detachably engaged with the bayonet 13 surrounding the air outlet 14 of the body 1.

[0060] In order to further enhance the formaldehyde removal effect, an upwardly open volatilization tank 22 is provided around the filter pipe 21, and the volatilization tank 22 is filled with volatile formaldehyde removal gel. The breathable cover plate 23 is connected to the upper end of the formaldehyde adsorption component 2, covering the filter pipe 21 and the volatilization tank 22. The air flow after the formaldehyde adsorption medium removes formaldehyde passes through the breathable cover plate 23 and is emitted upward. After the volatile formaldehyde removal gel volatilizes, it passes through the breathable cover plate 23, and with the help of the lifting effect of the air flow, it gradually diffuses as the air flow continues to rise, bringing the volatile formaldehyde removal gel upward to a higher height and then diffuses. Since the air above the volatilization tank 22 is continuously "sucked away" upward, the upward volatilization speed of the volatile formaldehyde removal gel in the volatilization tank 22 is further accelerated. Compared with the existing passive volatilization formaldehyde removal gel, the present invention greatly increases the effect of the volatile formaldehyde removal gel contacting with the air in the upper space, and improves the formaldehyde removal efficiency.

[0061] Figure 5 This is a schematic diagram of a fan for removing formaldehyde according to the present invention connected to a first nozzle assembly. Figure 5As shown, the present invention can also switch between a formaldehyde removal air purifier and a bladeless fan. A first nozzle assembly 3 can be connected to the air outlet 14 instead of the formaldehyde adsorption assembly 2, and the air flow passing through the first nozzle assembly 3 is emitted in a horizontal direction. At this time, the formaldehyde removal fan has the same user experience as a traditional bladeless fan.

[0062] Figure 6 This is a schematic diagram of a fan for removing formaldehyde according to the present invention connected to a filter pipe. Figure 6 As shown, in order to further enhance the effect of activated carbon in adsorbing formaldehyde, the present invention can also replace the filter pipeline 21 with N formaldehyde adsorption components 2 that are stacked and connected to form a growing filter pipeline. The air flow passes through each adsorption medium in the growing filter pipeline in the anti-gravity direction and is emitted upward. The adsorption of formaldehyde in the air is enhanced by stacking multiple formaldehyde adsorption components 2, thereby further improving the adsorption effect.

[0063] In addition, the present invention can also have the functions of a formaldehyde removal air purifier and a bladeless fan, by connecting a second nozzle assembly (not shown) to the upper end of the formaldehyde adsorption assembly 2 (mounted against the Figure 4 The upper end of the formaldehyde adsorption component 2 is connected to the second nozzle component), and the air after formaldehyde removal and the volatilized formaldehyde removal gel pass through the air flow of the second nozzle component and are emitted in the horizontal direction, thereby enhancing the ability of directional formaldehyde removal in the horizontal direction.

[0064] In summary, the purpose of the present invention is to provide a fan that effectively absorbs formaldehyde through active airflow, which is particularly helpful to enhance vertical air flow and formaldehyde adsorption. It is suitable for vertical formaldehyde removal in small spaces, significantly shortens the time period for formaldehyde removal, and protects the health of users.

[0065] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
