[0019] 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.

[0020] like Figure 1 , Figure 2 , Figure 3 As shown, a device for collecting tobacco volatiles in tobacco fields includes an upper mounting frame 1 and a lower mounting frame 2. Both the upper mounting frame 1 and the lower mounting frame 2 consist of left and right parts, which are interlocked and fixed by bolts. Four connecting posts 3 are arranged in a rectangular array on the opposite sides of the upper mounting frame 1 and the lower mounting frame 2. The four connecting posts 3 are inserted into the upper mounting frame 1 and the lower mounting frame 2. The outer sides of the upper mounting frame 1 and the lower mounting frame 2 are sealed with an odorless transparent polyethylene film 13. A top plate 4 is bolted to the upper side of the upper mounting frame 1. An air inlet pipe 11 is sealed and inserted into the side of the lower mounting frame 2. An air outlet pipe 10 is sealed and inserted into the side of the upper mounting frame 1. The air inlet pipe 11 is located on the left side of the lower mounting frame 2, and the air outlet pipe 10 is located on the right side of the upper mounting frame 1.

[0021] The top plate 4 is equipped with a collection component for collecting tobacco volatiles.

[0022] When installing the collection device, the staff placed the left and right parts of the lower mounting frame 2 on the left and right sides of the tobacco, and then connected and fixed the left and right parts of the lower mounting frame 2 with bolts. Then, the staff inserted four connecting posts 3 into the lower mounting frame 2 and inserted the upper mounting frame 1 into the four connecting posts 3. After the upper mounting frame 1 was installed, the staff installed the top plate 4 onto the upper side of the upper mounting frame 1 with bolts to complete the installation of the main body of the collection device. Then, the staff connected the collection components and the exhaust pipe. Finally, the staff used sealant to seal and cover the lower side of the upper mounting frame 1 and the lower mounting frame 2 with odorless transparent polyethylene film 13 to prevent outside air from directly entering the inside of the collection device.

[0023] During collection, staff activate the collection unit. Tobacco volatiles are allowed to enter the collection unit through the exhaust pipe, while outside air enters the collection device through the air inlet pipe 11 to ensure atmospheric pressure balance inside the collection device and normal respiration of the tobacco.

[0024] Furthermore, the collection component includes an air pump 6 bolted to the upper side of the top plate 4. The air pump 6 and the air outlet pipe 10 are connected by a threaded sealing air guide pipe 9. An adsorption pipe 8 is detachably connected to the air guide pipe 9 by a thread. The adsorption pipe 8 is filled with adsorbent. In use, the air pump 6 can draw the air inside the collection device through the exhaust pipe. The drawn air enters the adsorption pipe 8 through the air guide pipe 9. The adsorbent in the adsorption pipe 8 can adsorb the tobacco volatiles in the air, thereby completing the collection of tobacco volatiles.

[0025] Furthermore, the adsorbent is Tenax-TA, which is a widely used adsorbent for the capture of volatile organic compounds (VOCs), especially suitable for dynamic vacuum adsorption and thermal desorption technologies. Tenax-TA has excellent adsorption performance for neutral and hydrophobic compounds and exhibits excellent capture ability for low- to medium-polarity compounds (such as terpenes, ketones, and esters).

[0026] Furthermore, a gas flow meter 7 is installed on the gas guide pipe 9. The gas flow meter 7 is located on the side of the gas guide pipe 9 close to the air pump 6. During use, the gas flow meter 7 can detect the gas flow rate in the gas guide pipe 9, which makes it convenient for the staff to adjust the pumping rate through the air pump 6.

[0027] Furthermore, a temperature and humidity sensor 5 is bolted to the upper side of the top plate 4. The detection end of the temperature and humidity sensor 5 passes through the top plate 4 and extends to the lower mounting bracket 2. The detection end of the temperature sensor 13 is located inside the odorless transparent polyethylene film 13. In use, the temperature and humidity sensor 5 can detect the temperature and humidity of the environment inside the collection device, which makes it easier for staff to record the impact of environmental factors on tobacco volatiles.

[0028] Furthermore, an activated carbon tube 12 is installed at one end of the air intake pipe 11 outside the lower mounting bracket 2 via a threaded seal. During use, the activated carbon tube 12 can adsorb impurities in the air inside and outside the collection device, thereby reducing the influence of impurities in the outside air on the collection results and improving the accuracy of the collection results.

[0029] Furthermore, the lower mounting frame 2 has an integrally formed plug-in block 201 on its lower side. The cross-section of the plug-in block 201 is an inverted right triangle. In use, the lower mounting frame 2 can be plugged into the ground through the plug-in block 201, which improves the connection strength between the lower mounting frame 2 and the ground, thereby improving the reliability of the data acquisition device in use.

[0030] Although the present invention 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 invention should be included within the protection scope of the present invention.
