Description

Technical Field

[0001] This utility model relates to the field of air purification technology, specifically to a layered adsorption and decomposition type indoor formaldehyde air purification device. Background Technology

[0002] Air purifiers mainly consist of a motor, fan, and air filter system. Their working principle is as follows: the motor and fan inside the machine circulate indoor air. Polluted air passes through the air filter, which removes or adsorbs various pollutants, continuously ionizing the air to generate a large number of negative ions. These negative ions are then emitted by the fan, forming a negative ion airflow, thus achieving the purpose of cleaning and purifying the air. Formaldehyde has a strong irritant effect on the mucous membranes of the eyes, nose, and throat. The most common symptoms are eye irritation and headaches; in severe cases, it can cause allergic dermatitis and asthma. Air purification devices are usually used when treating formaldehyde.

[0003] Publication No. CN220892478U discloses an indoor formaldehyde removal air purification device, which includes a sliding groove, an activated carbon filter, a fixed handle, a circular groove, a spring, a round head, a formaldehyde removal filter, and a deodorizing filter. The activated carbon filter effectively purifies and filters formaldehyde. The activated carbon filter can be directly inserted during installation and easily removed for replacement or cleaning, making it simple to operate and easy to install and disassemble. The round head, through the spring force, presses against the inner wall of the sliding groove, making the activated carbon filter installation more stable. However, this patent still has the following problems in actual use:

[0004] Although this indoor formaldehyde removal air purifier can effectively purify and filter formaldehyde by incorporating activated carbon filters, formaldehyde removal filters, and deodorizing filters, it is not convenient to adjust the angle during formaldehyde removal. Adjusting the height alone cannot achieve rapid air circulation, thus affecting the efficiency of formaldehyde removal. Furthermore, the dust filter lacks a cleaning mechanism, causing dust to adhere to it, which in turn hinders air circulation and is not conducive to rapid formaldehyde removal.

[0005] Therefore, a layered adsorption and decomposition type indoor formaldehyde air purification device is proposed to solve the problems mentioned above. Utility Model Content

The bottom of the layered adsorption mechanism 1 is provided with a lifting and rotating mechanism 2, and the top of the lifting and rotating mechanism 2 is fixedly installed with a rotating worm gear 214. The layered adsorption mechanism 1 includes an inclined fixed seat 101. A first sprocket limiting cover 102 is fixedly installed on one side of the inclined fixed seat 101. An inclined motor 103 is fixedly installed on one side inside the first sprocket limiting cover 102. The output end of the inclined motor 103 is fixedly connected to a first sprocket transmission assembly 104. Inclined threaded rods 105 are symmetrically installed on the outer side of the first sprocket transmission assembly 104. Inclined threaded sleeves 106 are threadedly connected to the outer sides of both inclined threaded rods 105. An inclined rotating rod 107 is rotatably connected to the top of the inclined threaded sleeves 106. The top of the inclined rotating rod 107 rotates.

The rotating support 109 is fixedly installed on the top of the tilting fixed base 101. The layered purification box 110 is fixedly installed inside the tilting bracket 108. Several layered adsorption and decomposition activated carbon plates 111 are inserted inside the layered purification box 110.

A rotating worm wheel 214 is meshed with the rotating worm 213. The rotating worm wheel 214 is rotatably connected to the lifting sliding plate 209 and the worm wheel protective cover 210. The rotating worm wheel 214 is fixedly installed at the bottom of the inclined fixed seat 101. The lifting motor 205 drives the lifting threaded rod 206 to rotate, which causes the lifting threaded bracket 207 to drive the lifting sliding rod 208 and the lifting sliding plate 209 to move up and down, thereby adjusting the height of the layered purification box 110. At the same time, the rotating motor 212 is started to drive the rotating worm 213 to rotate. Utilizing the meshing connection between the rotating worm 213 and the rotating worm wheel 214, the rotating worm wheel 214 drives the inclined fixed seat 101 to rotate horizontally, thereby enabling all-round formaldehyde removal in the room and improving the air purification effect.

[0033] Working principle: Before using this layered adsorption and decomposition type indoor formaldehyde air purifier, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 6As shown, firstly, the lifting motor 205 drives the lifting threaded rod 206 to rotate, causing the lifting threaded bracket 207 to move the lifting sliding rod 208 and the lifting sliding plate 209 up and down, thereby adjusting the height of the layered purification box 110. Simultaneously, the rotating motor 212 starts, driving the rotating worm gear 213 to rotate. Utilizing the meshing connection between the rotating worm gear 213 and the rotating worm wheel 214, the rotating worm wheel 214 drives the inclined fixed seat 101 to rotate horizontally, thus enabling all-around formaldehyde removal indoors and improving air purification. Secondly, the tilting motor 103 drives the first sprocket transmission assembly 104 and the tilting threaded rod 105 to rotate, causing the tilting threaded sleeve 106 to move outside the tilting threaded rod 105 while simultaneously rotating the tilting rotating rod 107. This, combined with the action of the rotating support 109... The system enables the tilting bracket 108 and the layered purification box 110 to rotate. By adjusting the tilt angle of the layered purification box 110, the exhaust fan 113 inside the layered purification box 110 can be used to draw in air, and the layered adsorption and decomposition activated carbon plate 111 can be used to adsorb and purify formaldehyde in the air, improving the efficiency of air circulation. Finally, the dust screen 112 is used to filter dust in the air, and the cleaning motor 116 is started to drive the second sprocket transmission assembly 117 and the cleaning threaded rod 118 to rotate, so that the cleaning threaded sleeve 119 drives the cleaning bracket 120 and the rotating gear 121 to move.
