[0002] As the name suggests, engineered wood products are made from scraps and waste generated during wood processing, with the addition of chemical adhesives. There are many types of engineered wood products, the most common of which are particleboard, medium-density fiberboard (MDF), blockboard, plywood, and decorative engineered wood products such as fire-resistant boards.

[0003] Newly manufactured furniture and newly made engineered wood products typically have high formaldehyde content. Although furniture manufacturers have adopted various methods to minimize the actual amount of formaldehyde used, the phenomenon of formaldehyde release from engineered wood products and furniture is still widespread.

[0004] Patent application number 2019224947247 discloses a purification and adsorption box for removing formaldehyde from engineered wood products. The method involves stacking the engineered wood products in the purification box and then using an ultraviolet lamp to decompose the formaldehyde released by the products. Afterward, an exhaust fan is used to expel the decomposed formaldehyde along with the air. However, the engineered wood products still release formaldehyde at room temperature. In the above-mentioned prior art, the amount of formaldehyde released by the engineered wood products at room temperature is limited, which means that the engineered wood products still contain a large amount of formaldehyde, and still pose a problem of health hazards and air pollution.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1-6 One embodiment provided by this utility model:

[0033] A purification and adsorption box for removing formaldehyde from boards includes: an adsorption box 1, a heating box 4, and a drive motor.

[0034] In this case, multiple support plates 7 are fixedly installed on both sides of the inner cavity of the adsorption box 1 along the vertical direction to support the plate. After the plate is placed into the inner cavity of the adsorption box 1, the bottom sides of the plate simultaneously fit against the top of the two support plates 7 located on the same horizontal line to support the plate.

[0035] Multiple support plates 7 can be used to support multiple plates and are placed sequentially along the vertical direction.

[0036] Heating box 4 is fixedly installed on top of adsorption box 1, and heating coil 9 is fixedly installed in the inner cavity of adsorption box 1. A heat-conducting pipe 5 connected to its own inner cavity is fixedly installed on the top of adsorption box 1. The end of heat-conducting pipe 5 away from heating box 4 extends to the rear of adsorption box 1. Multiple conduits are fixedly installed on the outer wall of heat-conducting pipe 5. Multiple mounting holes adapted to the conduits are opened vertically on the outer wall of adsorption box 1 away from its opening end. The ends of multiple conduits away from heat-conducting pipe 5 are inserted into the inner cavity of the mounting holes. When the board is placed in the inner cavity of adsorption box 1, heating coil 9 is energized. After heating coil 9 is energized, the air in the inner cavity of heating box 4 is heated. The heated air enters the inner cavity of heat-conducting pipe 5 and is transmitted to the inner cavity of adsorption box 1 through multiple conduits via heat-conducting pipe 5, thereby exchanging heat with the air in the inner cavity of adsorption box 1. This heats multiple boards in adsorption box 1, allowing formaldehyde inside the boards to be released.

[0037] The drive motor is fixedly installed at the bottom of the inner cavity of the heating box 4, and the power output end of the drive motor is fixedly installed with a turbulence fan blade 10. The drive motor is located directly below the heating coil 9. When the heating coil 9 is energized, the drive motor is started. At this time, the turbulence fan blade 10 rotates together with the power output end of the drive motor, increasing the air flow rate inside the heating box 4. The heated air inside the heating box 4 is quickly transferred to the inner cavity of the adsorption box 1 through the heat conduction pipe 5 and multiple conduits, thereby increasing the heating rate of the air around the multiple boards in the inner cavity of the adsorption box 1. This is beneficial for the rapid release of formaldehyde from the boards and reduces the harm to the health of users during later use of the boards.

[0038] Multiple ultraviolet lamps 6 are fixedly installed vertically in the inner cavity of the adsorption box 1. After the formaldehyde in the board mixes with the air in the adsorption box 1, the formaldehyde molecules in the air can be decomposed by the ultraviolet lamps 6, and the formaldehyde molecules can be decomposed into carbon dioxide and water, thus eliminating the formaldehyde in the air.

[0039] Multiple ultraviolet lamps 6 and multiple support plates 7 are staggered to ensure that the ultraviolet lamps 6 irradiate the air inside the adsorption box 1 evenly, and that the outer walls of multiple boards are also irradiated by the ultraviolet lamps 6. This prevents the boards from blocking the light emitted by the ultraviolet lamps 6, thereby accelerating the decomposition of formaldehyde molecules in the air.

[0040] The staggered arrangement of multiple mounting holes and multiple support plates 7 facilitates uniform heating of the top and bottom of multiple panels, thereby increasing the rate of formaldehyde release from the panels.

[0041] Multiple rollers 8 are mounted on the top of multiple support plates 7, rotating along the sliding direction of the plate. When the bottom of the plate is placed directly above one of the support plates 7, the bottom of the plate and the top of the roller 8 are brought into contact. Then, one end of the plate is pushed, and the plate moves into the inner cavity of the adsorption box 1. At the same time, the roller 8 rotates along the tangent to the plate until the plate is completely moved into the inner cavity of the adsorption box 1. This reduces the resistance when the plate enters the inner cavity of the adsorption box 1 and improves the smoothness of the plate's movement in the inner cavity of the adsorption box 1.

[0042] Multiple support plates 7 are provided with heat-permeable holes at their tops. The multiple heat-permeable holes and multiple rollers 8 are arranged alternately. The heated air in the inner cavity of the adsorption box 1 passes through the heat-permeable holes and acts on the bottom of the board, thereby making the bottom of the board evenly heated and further accelerating the rate at which the board releases formaldehyde.

[0043] The top of the adsorption box 1 has a through hole that communicates with its own inner cavity. An air outlet pipe 3 is installed in the inner cavity of the through hole by threaded connection. Both ends of the air outlet pipe 3 are fitted with a perforated plate 2 by threaded connection. The inner cavity of the air outlet pipe 3 is filled with activated carbon. After the formaldehyde released by the board mixes with the air in the adsorption box 1, due to the rotation of the turbulence fan blade 10, the air in the adsorption box 1 passes through the perforated plate 2 at the bottom of the air outlet pipe 3 and quickly enters the inner cavity of the air outlet pipe 3. At this time, the activated carbon in the inner cavity of the air outlet pipe 3 can adsorb the residual formaldehyde in the air. Then, the air passes through the activated carbon and mixes with the outside air of the adsorption box 1 through the perforated plate 2 at the other end of the air outlet pipe 3, preventing the formaldehyde from mixing with the outside air and causing pollution to the outside air.

[0044] When the activated carbon inside the vent pipe 3 needs to be replaced, separate one of the mesh plates 2 from one end of the vent pipe 3, then invert the vent pipe 3. The activated carbon in the vent pipe 3 will slide to the outside of the vent pipe 3 under the action of gravity, thereby replacing the activated carbon in the vent pipe 3. Then, place the prepared activated carbon inside the vent pipe 3, and then connect the mesh plate 2 to one end of the vent pipe 3 with threads to block the activated carbon in the vent pipe 3 and prevent the activated carbon inside the vent pipe 3 from falling out.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
