Description

Technical Field

[0001] The utility model belongs to the technical field of formaldehyde treatment, and particularly relates to a treatment device. Background Art

[0002] Formaldehyde is a common organic compound and also a harmful substance. It exists in many building and decoration materials such as household decoration materials, furniture, glue, coatings, etc., and is released into the indoor air. Long-term and high-concentration exposure to formaldehyde can cause health problems, such as irritating the eyes, throat and skin, causing allergic and respiratory diseases such as asthma, and may even damage the liver and central nervous system. Therefore, the goal of a formaldehyde treatment device is to reduce the concentration of formaldehyde in the indoor air and reduce the harm to human health. After the formaldehyde treatment device is used for a long time, formaldehyde will be adsorbed inside the device, such as on the filter screen. Therefore, it is necessary to regularly maintain the formaldehyde filtering device, such as replacing the filter screen, cleaning the equipment or repairing damaged parts, to ensure the normal operation of the device. Secondly, when the formaldehyde treatment device is maintained, the device needs to be disassembled. If the structure of the device is too complex, it will increase the maintenance time and cost. Therefore, it is hoped to propose a new structure to solve the above problems. Summary of the Utility Model

There is a wall on the front side of the formaldehyde treatment device. There is an installation hole opened on the back surface of the wall. The formaldehyde treatment device is installed inside the installation hole through a connecting mechanism. The air outlet pipe is buried in front of the installation hole.

[0027] A set of placement cavities 230 are formed by the rear side of the fixing base 190 being recessed forward. A formaldehyde treatment box 220 is provided inside the placement cavities 230. A number of groups of ventilation holes are opened through the top and bottom of the formaldehyde treatment box 220. Activated carbon particles are contained inside the formaldehyde treatment box 220.

[0028] The interior of the placement cavity 230 is provided with two sets of disassembly and assembly sliding grooves 250. The outer side of the formaldehyde treatment box 220 is provided with two sets of disassembly and assembly sliding strips 240.

[0030] The device main body 100, the dust-proof cover 120, the formaldehyde treatment cavity 110, the formaldehyde treatment box 220, the fixed base 190, and the flow concentrating cover 170 are all made of stainless steel. The flow concentrating cover 170 is a horn-shaped structure with a gradually increasing diameter from the back to the front. The radius length of the front opening of the flow concentrating cover 170 is equal to the radius length of the back of the fixed base 190. During actual use, the air containing formaldehyde enters the interior of the formaldehyde treatment cavity 110 and flows forward. After being concentrated by the flow concentrating cover 170, the air flows towards the fixed base 190. When passing through the formaldehyde filter net 180, formaldehyde molecules are adsorbed by the formaldehyde filter net 180. Then the initially treated air continues to enter the interior of the formaldehyde treatment box 220 through the ventilation holes on the back of the formaldehyde treatment box 220 and is adsorbed and treated by the activated carbon particles inside the formaldehyde treatment box 220. The air after secondary treatment enters the interior of the device main body 100 through the ventilation holes on the front of the formaldehyde treatment box 220 and finally enters the air outlet duct through the air outlet 130 and is finally discharged outdoors. The final effect is that through the formaldehyde filter net 180 and the formaldehyde treatment box 220, the air containing formaldehyde molecules can be filtered twice, so that the formaldehyde molecules in the air can be adsorbed and treated to prevent the concentration of formaldehyde molecules in the room from being too high and causing harm to the human body.

[0031] Example 1: Please refer to Figures 1 to 5, during actual use, the formaldehyde treatment device is installed inside the installation hole on the back of the wall. The air outlet 130 at the rear side of the device main body 100 is fixedly connected to the air outlet pipe. When formaldehyde treatment of the room is required, the device main body 100 is started to make the air extraction mechanism inside the device main body 100 work. The air extraction mechanism sucks the external air containing formaldehyde into the formaldehyde treatment device. The air containing formaldehyde first enters the formaldehyde treatment chamber 110 forward through the dust-proof cover 120. At this time, the dust-proof net 160 filters large-particle impurities in the air to prevent large-particle impurities (such as paper scraps or suspended substances) from entering the device main body 100 and damaging the air extraction mechanism, affecting the normal operation of the device main body 100;

[0032] After the air containing formaldehyde enters the formaldehyde treatment chamber 110 and flows forward, it is converged by the converging cover 170 and then flows in the direction of the fixed base 190. When passing through the formaldehyde filter screen 180, formaldehyde molecules are adsorbed by the formaldehyde filter screen 180. Then, the initially treated air continues to enter the formaldehyde treatment box 220 through the ventilation holes on the back of the formaldehyde treatment box 220 and is adsorbed and treated by the activated carbon particles inside the formaldehyde treatment box 220. The air after secondary treatment passes through the ventilation holes on the front of the formaldehyde treatment box 220 and enters the device main body 100 forward, and finally enters the air outlet pipe through the air outlet 130 and is finally discharged outdoors. The final effect is that through the formaldehyde filter screen 180 and the formaldehyde treatment box 220, the air containing formaldehyde molecules can be filtered twice, so that the formaldehyde molecules in the air can be adsorbed and treated to prevent the concentration of formaldehyde molecules in the room from being too high and causing harm to the human body.

[0033] Example 2: Please refer to Figure 1 、 Figure 2 and Figure 5 , when maintenance of the formaldehyde treatment device is required, first use tools to disassemble the formaldehyde treatment device from inside the installation hole. Then one person holds the outside of the device main body 100, and the other person holds the outside of the dust-proof cover 120 and rotates it to disconnect the threaded connecting pipe 140 from the installation groove 150, so as to remove the dust-proof cover 120, and then the dust-proof net 160 can be maintained and cleaned;

[0034] After the dust-proof cover 120 is disassembled, keep the device main body 100 held still. The other person puts their hand through the converging cover 170 and holds the formaldehyde filter screen 180, and then rotates the formaldehyde filter screen 180 to disconnect the threaded connecting pipe 200 from the installation groove 210, so as to take out the formaldehyde filter screen 180, exposing the placement cavity 230. Then invert the device main body 100 so that the two sets of disassembly and assembly sliding strips 240 move along the two sets of disassembly and assembly sliding grooves 250, and the formaldehyde treatment box 220 inside the fixed base 190 falls out of the placement cavity 230, and then the formaldehyde treatment box 220 can be taken out, which is convenient for maintaining and replacing the formaldehyde filter screen 180 and the formaldehyde treatment box 220 and improving work efficiency.

[0035] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
