Description

Technical Field

[0001] The utility model relates to the technical field of environmentally friendly formaldehyde removal in indoor decoration, in particular to an environmentally friendly formaldehyde removal device for indoor decoration. Background Art

[0002] As people's living standards improve, their requirements for housing are also becoming more stringent. Therefore, people decorate and design their homes according to their own preferences. During interior decoration, new furniture and painted walls contain some formaldehyde, which affects the health of users. Therefore, formaldehyde removal equipment is needed to remove it.

[0003] After searching, Chinese patent application No. 201921874741.7 discloses an environmentally friendly formaldehyde removal device for interior decoration, including: a device body, a cavity, an air inlet pipe and a water storage cavity. A cleaning component is arranged inside the device body, and a drying component is arranged on the right side of the device body. A cavity is arranged at the right end of the device body, and a reinforcing rib is fixedly connected to the connection between the device body and the cavity. Through the arrangement of the heating plate, the temperature of the air increases after being heated by the heating plate, so that the indoor air temperature increases. By dissipating the hot air indoors, it is convenient to volatilize the formaldehyde in the indoor air and increase the volatilization rate of the formaldehyde. Through the arrangement of the movable plate, it is in a vertically closed state in a windless state, so as to avoid the rapid loss of temperature in the cavity and improve the thermal insulation effect of the device. When there is wind passing by, the wind blows the movable plate, driving the movable plate to be in an inclined state, which is convenient for air discharge. By utilizing the arrangement of the sealing ring, water is prevented from penetrating out of the device when the movable plate and the water outlet are closed.

[0004] Although the above patent can increase the temperature of the air after it passes through the heating plate, thereby increasing the indoor air temperature, and by dissipating the hot air indoors, it is easy to volatilize the formaldehyde in the indoor air and increase the volatilization rate of formaldehyde. However, in actual use, when the hot air meets the cold air outdoors, the water molecules in the air will liquefy, and then the liquefied water droplets will adhere to the indoor decoration materials, which may corrode the indoor decoration materials and affect the subsequent use. In addition, the patent only adsorbs formaldehyde through the activated carbon filter. Although it can remove the formaldehyde emitted in the indoor air, it cannot absorb and remove the formaldehyde quickly and efficiently, so the formaldehyde removal rate is slow.

[0005] Therefore, it is necessary to modify the formaldehyde removal device in the above patent to effectively prevent the corrosion of decoration materials caused by water droplets generated by the cooling of hot air, and to adsorb formaldehyde only through the activated carbon filter. Although it can remove formaldehyde emitted in the indoor air, it cannot absorb and remove formaldehyde quickly and efficiently, resulting in a slow formaldehyde removal speed. Utility Model Content
