Description

Technical Field

[0001] The utility model relates to the field of air purification, in particular to an air purification device for removing formaldehyde. Background Art

[0002] Formaldehyde is a colorless gas with a pungent odor. It is often used in industrial production as a preservative, disinfectant, and adhesive. Formaldehyde is also found in some home decoration materials, furniture, and cosmetics. Long-term exposure to high concentrations of formaldehyde may have certain effects on human health, such as irritation to the eyes, respiratory tract, and skin, and may even cause chronic respiratory diseases.

[0003] The types of formaldehyde treatment devices on the market include activated carbon filters, water catalyst devices, water decomposition devices and plant purifiers. Most of the formaldehyde removal devices on the market use activated carbon adsorption treatment, using the pore structure on the surface of activated carbon to adsorb formaldehyde in the air. Since the contact area between air and the surface of activated carbon is limited, the adsorption of formaldehyde is a very long process, and the formaldehyde adsorption of activated carbon will also have a saturation upper limit, which will cause the adsorption effect to be unsatisfactory. How to invent a formaldehyde removal air purification device to improve these problems has become a problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides an air purification device for removing formaldehyde, aiming to improve the problems of too long formaldehyde removal time and unsatisfactory activated carbon purification.

[0007] Preferably, the filtering mechanism includes a filter element holder, activated carbon and a handle on the side for disassembly, the filter element holder is used to fix the filter element for filtering formaldehyde, and the filter element is fixed inside the holder to prevent it from falling, and the activated carbon is the filter element for filtering formaldehyde.

[0008] Preferably, a sliding track is provided on the inner wall of the shell, and a sliding groove corresponding to the sliding track is provided on the side of the filter element bracket.

[0009] Preferably, the air inlet is arranged at a lower portion of the housing.

[0010] Preferably, both ends of the cross bar are fixedly connected to the inner wall of the shell and the width of the cross bar is greater than the diameter of the rotating shaft, and the rotating shaft is rotatably connected to the middle part of the cross bar.

[0011] Preferably, the connecting block between the universal wheel and the housing is a telescopic column, and the height of the air inlet can be adjusted by adjusting the length of the telescopic column.

[0012] The beneficial effects of the utility model are as follows: the utility model drives the fan to rotate through a motor, so as to suck the air in the room into the device, increase the flow of air, and realize the adsorption of formaldehyde by activated carbon at a higher rate; the formaldehyde remover can be atomized and sprayed to the inside of the device through an atomizer to remove the formaldehyde that cannot be completely adsorbed by the activated carbon; and the atomized formaldehyde remover can also be discharged into the air in the room through the fan at the upper end of the rotating shaft to purify the formaldehyde.

[0022] It should be noted that: since the density of formaldehyde is greater than the density of air, formaldehyde will float on the bottom surface of the room. Setting the air inlet 2 at the lower part of the device is more conducive to the device's absorption of formaldehyde and plays an air purification role; the universal wheel 5 is convenient for the movement of the device, and the room for eliminating formaldehyde can be changed at will; the filter mechanism can be installed and disassembled by the push-pull handle 15, and the filter mechanism can be disassembled to replace the long-used filter element activated carbon 14 inside the filter element holder 4; sliding tracks 9 and slide grooves 13 are set on the inner wall of the outer shell 1 and the side of the filter element holder 4 to limit the position of the filter mechanism and prevent installation deviations that affect the effect of removing formaldehyde.

[0023] Furthermore, a motor 6 is fixedly installed on the upper side of the universal wheel 5 inside the shell 1, a rotating shaft 7 is fixedly installed on the output end of the motor 6, a fan 8 is installed in the middle and upper parts of the rotating shaft 7, a cross bar 16 is fixedly installed on the upper side of the middle fan 8 and the rotating shaft 7 passes through the cross bar 16, both ends of the cross bar 16 are fixedly connected to the inner wall of the shell 1 and the width of the cross bar 16 is greater than the diameter of the rotating shaft 7, the rotating shaft 7 is rotatably connected to the middle part of the cross bar 16, an atomizer 10 is fixedly installed on the inner wall of the shell 1, a water inlet 11 of the atomizer 10 is on the side of the shell 1, a nozzle 12 of the atomizer 10 is arranged on the side away from the water inlet 11 and the nozzle 12 points to the fan 8 on the upper side of the rotating shaft 7.

[0024] It should be noted that the fan 8 in the middle of the rotating shaft 7 is used to suck air into the device from the air inlet 2, while the fan 8 at the upper end of the rotating shaft 7 is used to discharge the purified air in the device and the atomized liquid sprayed by the atomizer 10 from the exhaust port 3; formaldehyde scavenger is added from the water inlet 11 of the atomizer 10 (it should be noted that the main chemical components of the formaldehyde scavenger are negative ion thermoelectric effect reaction solution, surface sealing agent, active amino group, etc.), the atomizer 10 can atomize the formaldehyde scavenger, spray it from the nozzle 12, and it is taken out of the device and sprayed into the air.

[0025] The working principle of this method is as follows: push the device into a room where formaldehyde needs to be removed, fix the universal wheel 5, add formaldehyde remover into the water inlet 11, turn on the motor 6 and the atomizer 10, and the rotation of the motor 6 drives the two fans 8 on the upper side of the rotating shaft 7 to rotate. The middle fan 8 draws the air in the room into the device and blows it to the surface of the activated carbon 14 of the filtering mechanism. The air flowing through the activated carbon 14 adsorbs formaldehyde and removes most of the formaldehyde; the atomizer 10 sprays the atomized formaldehyde remover (it should be noted that the atomizer 10 uses a model of PN600 to atomize the internal liquid through ultrasound. This is a prior art and will not be described in detail) from the nozzle 12, and the atomized formaldehyde remover is more dispersed in the air. The fan 8 at the upper end of the rotating shaft 7 discharges the purified air and the atomized formaldehyde remover from the exhaust port 3.

[0026] By pulling the handle 15 on the side of the filter mechanism, the entire filter mechanism can be pulled out of the device, and the saturated filter element activated carbon 14 can be replaced. The replaced filter mechanism is picked up, and the side slide groove 13 is aligned with the sliding track 9 on the inner wall and pushed in for installation.

[0027] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0028] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
