[0003] For example, a temperature control device for wood fumigation with authorization announcement number "CN213423782U" has a detachable connection between an adsorption plate and a sealing block, allowing users to replace the adsorption plate more conveniently and efficiently, thereby improving efficiency. However, when fumigating and controlling the temperature of wood, the temperature control device for wood fumigation requires workers to frequently manually turn a rotary switch to open the notch of the housing, thereby increasing the labor of the workers. At the same time, when fumigating the wood in the box 1, the workers cannot observe the fumigation status of the wood in real time, and thus cannot well control the fumigation time of the wood, resulting in the quality of the fumigated wood not meeting expectations, thereby reducing the quality of the work. Utility Model Content

A temperature control device for wood fumigation is proposed.

[0028] Working principle: (wood is wood board)

[0029] When it is necessary to control the temperature when fumigating wood, the worker places the wood to be fumigated on the horizontal board 7, closes the box door 8 after the wood is placed on the horizontal board 7, and then connects the nozzles 6 on the left and right sides to the external fumigator. The external fumigator converts the water and Chinese medicine in the external water tank into high-temperature steam by heating and atomizing, and converts the water and Chinese medicine in the external water tank into steam and slowly releases them into the nozzle 6 through the air outlet of the fumigator and then sprays them into the box body 1 through the nozzle 6. The high-temperature steam generated by the fumigator contacts the wood and then fumigates the wood to achieve the effect of killing insects and preserving corrosion. During the wood fumigation, the worker can observe the fumigation of the wood in the box body 1 through the observation window 9, and the mist in the box body 1 will adhere to the observation window 9 and thus block the worker's field of vision. At this time, the worker moves the support rod 304 upwards, and the spring 304 is ejected. The spring 305 contracts, and when the support rod 304 is separated from the column 302, the support rod 304 stops pulling and remains stationary, and the limit on the column 302 is cancelled in the above manner. Then the worker rotates the column 302, and the column 302 drives the vertical rod 303 to rotate. The rubber layer on the vertical rod 303 contacts the observation window 9 and clears the mist attached to the observation window 9. After the mist on the observation window 9 is cleared, the column 302 is rotated in the opposite direction to reset it. After the column 302 is reset, the support rod 304 is released, and the spring 305 rebounds and drives the vertical rod 304 to reset and engage with the column 302 again, thereby limiting it. In the above manner, the mist attached to the observation window 9 is cleared, thereby preventing the mist from blocking the worker's field of vision (if the mist on the observation window 9 is not cleaned thoroughly, the observation window 9 can be cleaned multiple times according to the above method);

[0030] During the fumigation of wood, the air pressure in the box 1 can be discharged through the pressure relief valve, and the temperature in the box 1 can be observed by the background computer (the temperature sensor 5 is connected to the background computer through a wire, and the temperature sensor 5 transmits the data of the temperature in the box 1 to the background computer). If the temperature in the box 1 is high, the external power supply of the servo motors 203 on both sides is turned on and started, and the left servo motor 203 drives the left gear 204 to rotate clockwise, and the left gear 204 drives the left rack 205 to move left, thereby causing the first plate 10 to move left. At the same time, the right servo motor 203 drives the right gear 204 to rotate counterclockwise, and the right gear 204 drives the right rack 205 to move right, thereby driving the second plate 10 to move right. In this way, the first plate 10 moves to the left, and the second plate 11 moves to the right to open the gap above the box 1. When the gap above the box 1 is opened, the two servo motors 203 are turned off;

[0031] Then the mist in the box body 1 will be discharged outside the box body 1 through the gap above the box body 1. After the temperature in the box body 1 reaches the required working temperature, the two servo motors 203 are started according to the above method to reset the first plate 10 and the second plate 11 and make the first plate 10 and the second plate 11 fit together again, thereby closing the gap above the box body 1. The temperature control work in the box body 1 is completed in the above method (in the process of controlling the temperature of the box body 1, the servo motors 203 on both sides can be used to control the distance between the first plate 10 and the second plate 11 to control the size of the opening of the gap above the box body 1. When the gap above the box body 1 is larger, the mist in the box body 1 will dissipate faster, and when the gap above the box body 1 is smaller, the mist in the box body 1 will dissipate more slowly. Workers can adjust the distance between the first plate 10 and the second plate 11 according to different needs);

[0032] After the wood is fumigated, the external fumigator is turned off, and then the box door 8 is opened. Then the worker uses the external clamp to move the wood that has just been fumigated out of the box body 1, and then the worker moves the new wood to the cross plate 7 and then performs the next round of fumigation on the new wood.
