Problems solved by technology

[0024] Because formaldehyde can become formalin solution after being dissolved in water, and high-concentration formalin has toxicity and has pungent smell, even if the purifying device of the present invention continues to play the effect of purifying formaldehyde, formaldehyde content is relatively high at the same time. Low, but the purification device needs to be installed outdoors for safety reasons

Embodiment 1

[0057] Embodiment 1, the technical solution it solves is that it is characterized in that it includes a wooden substrate 1, and the front side of the wooden substrate 1 is provided with a square groove 2 that does not pass through backwards, and the upper, lower, left and right sides of the square groove 2 are all A support plate 3 protrudes toward the center of the plank substrate 1, and each support plate 3 is fixedly connected with a triangular support block 4 at the protruding end of each support plate 3 toward the center of the square groove 2, and each support plate 3 and the triangular support block 4 divide the square groove 2 into A plurality of sound-insulating areas 5, each triangular support block 4 faces the side of the center of the square groove 2 to form a connecting area 6, each sound-insulating area 5 is inlaid with a sound-insulating block 7 corresponding to the shape, and the connecting area 6 is inlaid with a connecting area 6 The activated carbon filter bl...

Embodiment 2

[0059] Embodiment 2, on the basis of Embodiment 1, the drain valve 38 includes a square valve body 39, the square valve body 39 is provided with a longitudinal communication hole 40 having the same size and shape as the drainage pipe, and the valve body is provided with a through communication hole The spool groove 41 of the spool groove 41 is slidingly connected with the spool 42, and the spool 42 is fixedly connected with the push rod 37. The valve body is located in the communication hole and is provided with a tapered stopper, which is located on the front side of the spool 42. There is an unloading groove 43 on the top. When the valve core 42 is pushed into the valve body, the valve core 42 gradually blocks the communication hole until the communication hole is completely blocked. Connecting the longitudinal communication holes 40 allows the liquid in the collection cylinder 18 to flow out through the communication holes, and the disconnected state is restored when the val...

Embodiment 3

[0061] Embodiment 3. On the basis of Embodiment 1, the control device includes a rotary valve 44. A rotary valve core 45 is rotatably connected to the rotary valve core 45. A vertical communication hole 46 through the axis is opened on the rotary valve core 45, which is located at The front and rear sides of the rotating spool 45 are respectively provided with drainage grooves 47 protruding to the right, the second rotating motor 48 that controls the rotating spool 45 to rotate, and the limit rod 49 that limits the rotation angle of the second rotating motor 48 , the delivery pump 50 connected to the right end of the rotary valve 44, the outlet of the delivery pump 50 is connected to the upper end of the collection cylinder 18 through a hose, if the valve core 42 is in the rotary valve 44, if no formaldehyde is detected in the circulation cylinder, then the vertical communication hole 46 It is connected with the circulation cylinder, and the water in the circulation cylinder is...

Abstract

The formaldehyde-absorbable hollow wood board and its internal ventilation structure provided by the present invention not only solve the decorative effect on the wall during use, but also serve as a decorative wood board itself. Form a ventilation structure and purify the internal air, and at the same time filter the indoor air, and various toxic substances and odors volatilized by the wood board will enter the purification device through the internal communication structure and purify the gas through the purification device. Not only the hollow wood board itself can absorb formaldehyde in the air, but also can filter and clean the indoor air. After the formaldehyde volatilization is completed, it can also be used as an indoor air purification device.

Description

technical field [0001] The invention relates to a woodworking board, in particular to a hollow woodworking board capable of absorbing formaldehyde and its internal ventilation structure. Background technique [0002] The volatilization point of formaldehyde is at 19°C, and the higher the temperature, the more intense the volatilization; the other point is that the incubation period is as long as 3-15 years. These two characteristics make formaldehyde a "stubborn element" of air pollution. When heating in winter, most consumers' homes The temperature will be maintained at around 20°C. Then, this will create a powerful space for formaldehyde to volatilize. At 19°C, it will volatilize more than three times, and the higher the temperature, the more intense it is. , the concentration increased by 0.4 times, especially in spring and summer when the temperature rises and the release is more intense and the concentration will exceed 3 times the normal. [0003] According to the res...
