Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment, and more specifically, to a fan for removing formaldehyde. Background Technology

[0002] As living standards and technological levels continue to improve, people's demands for quality of life are increasing, making indoor air quality a major concern. This is especially true for newly renovated rooms, where wall paint, furniture, and other materials release formaldehyde during the first year, seriously impacting the health of residents.

[0003] Although products such as formaldehyde-removing plants, air purifiers, activated carbon, and formaldehyde-removing gels can absorb some formaldehyde, the efficiency of formaldehyde-removing plants is relatively low. Air purifiers cannot fit into long, narrow rectangular spaces like cabinets and wardrobes. Simply placing activated carbon at the bottom of a wardrobe only passively absorbs formaldehyde from the bottom, leaving the formaldehyde evaporating from the upper part of the wardrobe untreated. Similarly, placing formaldehyde-removing gel at the bottom of the wardrobe, due to its typically large particles, limits its effective upward evaporation height and cannot remove formaldehyde from the upper part. This results in a situation where, despite using many formaldehyde-removing products, poor air circulation inside the cabinet limits the effectiveness of passive adsorption methods, making it impossible to absorb formaldehyde in the short term.

[0004] Therefore, this invention provides a fan for removing formaldehyde. Utility Model Content

[0005] To address the problems in existing technologies, the purpose of this invention is to provide a fan for removing formaldehyde. This fan overcomes the limitations of existing technologies by effectively adsorbing formaldehyde through active airflow, especially by significantly lengthening the adsorption path in small spaces. This helps to enhance vertical airflow and formaldehyde adsorption, making it suitable for vertical formaldehyde removal in small spaces. It significantly shortens the formaldehyde removal time cycle and protects the user's health.

[0006] An embodiment of this utility model provides a fan, comprising:

[0007] The unit includes an air inlet, a fan for generating airflow, and an air outlet; and

[0008] A formaldehyde adsorption component is connected above the air outlet. The formaldehyde adsorption component includes a filter pipe extending in a vertical direction. A spiral guide is provided inside the filter pipe. The spiral guide and the inner wall of the filter pipe form a spiral air channel. A formaldehyde adsorption medium is provided inside the spiral air channel. The air flows through the spiral air channel, passes through the adsorption medium in the filter pipe, and is emitted in the anti-gravity direction.

[0009] Preferably, the spiral guide includes a column and a spiral guide plate extending spirally along the outer circumferential surface of the column. The outer circumferential surface of the column, the inner circumferential surface of the filter pipe, and the upper and lower surfaces of the spiral guide plate together define the spatial range of the spiral air passage.

[0010] Preferably, the fan includes an impeller, and the adsorption medium is located downstream of the fan.

[0011] Preferably, the formaldehyde adsorption medium is a plurality of activated carbon packets distributed along the spiral air passage.

[0012] Preferably, an upward-opening evaporation tank is provided around the filter pipe, and the evaporation tank is filled with volatile formaldehyde-removing gel, which evaporates upward due to the disturbance of the upward-emitted airflow.

[0013] Preferably, the filter pipe is a circular pipe, and the opening of the evaporation tank is an annular groove surrounding the upper end of the filter pipe.

[0014] Preferably, it further includes: a breathable retaining ring, wherein the breathable retaining ring is provided with a plurality of retaining members in the circumferential direction, and is engaged with the second retaining groove provided in the upper circumferential direction of the formaldehyde adsorption component by the retaining members, covering the volatilization groove and exposing the upper end of the spiral air channel; after the volatile formaldehyde removal gel volatilizes, it passes through the vent holes of the breathable retaining ring, and gradually diffuses after continuing to rise with the air flow.

[0015] Preferably, the bottom of the formaldehyde adsorption component is provided with a snap-fit, which is detachably snapped into the first slot surrounding the air outlet of the body.

[0016] Preferably, it further includes: a first nozzle assembly replacing the formaldehyde adsorption assembly and connected to the air outlet, wherein the airflow passing through the first nozzle assembly is emitted in a horizontal direction.

This helps enhance vertical airflow and formaldehyde adsorption, making it suitable for vertical formaldehyde removal in small spaces. It significantly shortens the formaldehyde removal time cycle and protects the user's health. Attached Figure Description

Figure 2 This is a three-dimensional exploded view of the formaldehyde-removing fan of this utility model. Figure 3 This is a cross-sectional view of the formaldehyde-removing fan of this utility model. Figures 1 to 3As shown, the formaldehyde removal fan of this invention includes: a main body 1 and a formaldehyde adsorption component 2. The main body 1 includes an air inlet 11, a fan 12 for generating airflow, and an air outlet 14. The formaldehyde adsorption component 2 is connected above the air outlet 14. The formaldehyde adsorption component 2 includes a filter pipe 26 extending vertically. A spiral guide 21 is provided inside the filter pipe 26. The spiral guide 21 and the inner wall of the filter pipe 26 combine to form a spiral air passage. A formaldehyde adsorption medium is placed inside the spiral air passage. Airflow passes through the spiral air passage and the adsorption medium inside the filter pipe 26 before being emitted in the anti-gravity direction. This invention significantly extends the airflow path through the filter pipe 26 by combining the filter pipe 26 and the spiral guide 21, thereby extending the path length of the formaldehyde adsorption medium within a smaller space and significantly enhancing the formaldehyde adsorption capacity.

[0051] In a preferred embodiment, the spiral guide 21 includes a column 27 and a spiral guide plate 28 extending spirally along the outer peripheral surface of the column 27. The outer peripheral surface of the column 27, the inner peripheral surface of the filter pipe 26, and the upper and lower surfaces of the spiral guide plate 28 together define the spatial range of the spiral air passage, but are not limited thereto.

[0052] In a preferred embodiment, the fan 12 includes an impeller with a high rotational speed that provides strong suction, and the adsorption medium is located downstream of the fan 12, but is not limited thereto.

[0053] In a preferred embodiment, the formaldehyde adsorption medium is a plurality of activated carbon packets distributed along the spiral airway. Since the length of the spiral airway is significantly greater than the length of the axial passage through the filter pipe 26, the present invention can use the spiral airway to set more activated carbon packets. The activated carbon packets can be attached to the upper and lower surfaces of the spiral guide plate 28 or the inner circumferential surface of the filter pipe 26, thereby multiplying the adsorption capacity, but not limited thereto.

[0054] In a preferred embodiment, an upward-opening evaporation tank 23 is provided around the filter pipe 26. The evaporation tank 23 is filled with volatile formaldehyde-removing gel. The volatile formaldehyde-removing gel evaporates upward due to the disturbance of the upward-emitting airflow, but is not limited thereto.

[0055] In a preferred embodiment, the filter pipe 26 is a circular pipe, and the opening of the evaporation tank 23 is an annular groove surrounding the upper end of the filter pipe 26, but is not limited thereto.

[0056] In a preferred embodiment, it further includes: a breathable retaining ring 22, which has a plurality of retaining members 25 arranged circumferentially, and is engaged with a plurality of second retaining grooves 29 arranged circumferentially at the upper end of the formaldehyde adsorption component 2 by the retaining members 25, covering the volatilization groove 23 and exposing the upper end of the spiral air channel; after the volatile formaldehyde removal gel volatilizes, it passes through the vent holes 24 of the breathable retaining ring 22, and continues to rise with the air flow and gradually diffuses, but is not limited thereto.

[0057] In a preferred embodiment, the bottom of the formaldehyde adsorption component 2 is provided with a snap-fit, which is detachably snapped into the first slot 13 of the surrounding air outlet 14 of the body 1, but is not limited thereto.

[0058] In a preferred embodiment, it further includes: a first nozzle assembly replacing the formaldehyde adsorption assembly 2 and connected to the air outlet 14, wherein the airflow passing through the first nozzle assembly is emitted in a horizontal direction, so that the present invention can be converted into a bladeless fan, but is not limited thereto.

[0059] In a preferred embodiment, it further includes: a second nozzle assembly connected to the upper end of the formaldehyde adsorption assembly 2. The air after formaldehyde removal and the volatilized formaldehyde removal gel are emitted horizontally through the airflow of the second nozzle assembly, so that the present invention can be converted into a bladeless fan with formaldehyde adsorption capacity, but is not limited thereto.

[0060] 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 this is not a limitation.

[0061] The specific usage of this utility model is as follows:

[0062] The formaldehyde removal fan body 1 of this invention includes an air inlet 11, a fan 12 for generating airflow, and an air outlet 14. A formaldehyde adsorption assembly 2 is connected above the air outlet 14. The formaldehyde adsorption assembly 2 includes a vertically extending filter pipe 26. A spiral guide 21 is provided inside the filter pipe 26. The spiral guide 21 and the inner wall of the filter pipe 26 combine to form a spiral air passage. A formaldehyde adsorption medium is placed inside the spiral air passage. Airflow passes through the spiral air passage and the adsorption medium inside the filter pipe 26 before being emitted in the anti-gravity direction. The spiral guide 21 includes a column 27 and a spiral guide plate 28 extending spirally along the outer circumferential surface of the column 27. The outer circumferential surface of the column 27, the inner circumferential surface of the filter pipe 26, and the upper and lower surfaces of the spiral guide plate 28 together define the spatial range of the spiral air passage. The fan 12 includes a high-speed impeller that provides strong suction. The adsorption medium is located downstream of the fan 12. This invention differs from most existing formaldehyde removal air purifiers in that existing models typically use a large, vertically positioned formaldehyde-removing filter before the air inlet of an axial flow fan. The axial flow fan draws air upwards, and the direction of airflow through the filter is perpendicular to the direction of airflow through the fan. While increasing the filter area can improve removal efficiency, this structure is bulky and difficult to fit into narrow spaces like wardrobes. This invention, however, uses a formaldehyde adsorption medium at the impeller outlet, ensuring that the direction of airflow through the impeller and through the adsorption medium is almost on the same axis. This significantly reduces the machine's size, making it particularly suitable for use in confined spaces like wardrobes. Furthermore, the formaldehyde adsorption medium consists of multiple activated carbon packets distributed along a spiral airflow channel. Since the length of the spiral airflow channel is significantly greater than the axial length of the filter pipe 26, this invention can accommodate more activated carbon packets within the spiral airflow channel, thus multiplying the adsorption capacity.

[0063] To further enhance the formaldehyde removal effect, an upward-opening evaporation groove 23 is provided around the filter pipe 26. The evaporation groove 23 is filled with volatile formaldehyde-removing gel, which evaporates upward due to the disturbance of the upward-emitting airflow. The filter pipe 26 is a circular tube, and the opening of the evaporation groove 23 is an annular groove surrounding the upper end of the filter pipe 26. The ventilated retaining ring 22 is provided with several retaining members 25 around its circumference. The retaining members 25 are engaged with the second retaining groove 29 circumferentially provided at the upper end of the formaldehyde adsorption component 2, covering the evaporation groove 23 and exposing the upper end of the spiral air passage. After the volatile formaldehyde-removing gel evaporates, it passes through the vent holes 24 of the ventilated retaining ring 22 and continues to rise with the airflow, gradually diffusing and carrying the volatile formaldehyde-removing gel to a higher height before diffusing again. As the air above the evaporation tank 23 is continuously "drawn away" upwards, the upward evaporation speed of the volatile formaldehyde removal gel in the evaporation tank 23 is further accelerated. Compared with the existing basic passive evaporation formaldehyde removal gel, this utility model greatly increases the contact effect between the volatile formaldehyde removal gel and the air in the upper space, thereby improving the formaldehyde removal efficiency.

[0064] In summary, the purpose of this utility model is to provide a fan that effectively adsorbs formaldehyde through active airflow, especially by greatly lengthening the adsorption path in small spaces. It is suitable for vertical formaldehyde removal in small spaces, significantly shortening the formaldehyde removal time cycle and protecting the user's health.

[0065] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
