[0002] Tobacco leaves can be placed in tobacco boxes during storage, and multiple tobacco boxes can be stacked in a warehouse. In order to detect the moisture content of tobacco leaves in tobacco boxes, the tobacco boxes can be opened manually, and tobacco leaf samples can be taken from the tobacco boxes and then measured using the oven method. Because the tobacco boxes are stored in stacks, when testing the moisture content of tobacco leaves in non-top tobacco boxes, the stack must be turned over or reversed first, and some tobacco boxes must be removed before the tobacco leaves to be tested can be taken out for testing, which increases the labor intensity of the tester and reduces the testing efficiency.

[0003] In order to reduce the labor intensity of the inspector and improve the inspection efficiency, Chinese patent CN220342337U discloses a handheld insertion type cigarette pack index inspection device. During the inspection, the inspection rod is inserted into the cigarette box, and measuring electrodes are installed at the top and middle position of the inspection rod of the inspection device. When the tobacco leaves contain a certain amount of moisture, the dielectric constant value of the tobacco leaves will change, thereby causing a change in capacitance, and then the change in capacitance between the electrodes is used to measure the moisture index of the tobacco leaves in the cigarette box. In this way, when checking the moisture content of the tobacco leaves, there is no need to move the cigarette box (that is, there is no need to turn over and over the stack).

[0004] However, the detection device uses electrodes to form a capacitor, detects the moisture content of the air in the cigarette box, and then uses the moisture content of the air in the cigarette box to estimate the moisture content of the tobacco leaves. Therefore, there is a problem that the measurement of the moisture content of the tobacco leaves is not accurate. Therefore, the existing detection device has the problem of inaccurate measurement when detecting the moisture content of the tobacco leaves in the cigarette box. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0042] Please also refer to Figures 1 to 3 In this embodiment, a tobacco moisture detection rod 1 is provided, which is used to detect the moisture of tobacco in a cigarette box 2, and includes an outer tube 10 and a receiving tube 12. The outer tube 10 includes a first air hole 1000. The outer tube 10 is inserted in the cigarette box 2. The receiving tube 12 is inserted in the outer tube 10, and the receiving tube 12 is provided with a second air hole 1220, and the second air hole 1220 is connected to the first air hole 1000, and the second air hole 1220 and the first air hole 1000 are located in the cigarette box 2. The receiving tube 12 is provided with dried shredded tobacco 13, and the water absorption rate of the shredded tobacco 13 is the same as that of tobacco leaves. The shredded tobacco 13 absorbs moisture in the air of the cigarette box 2 through the first air hole 1000 and the second air hole 1220, and the moisture absorbed by the shredded tobacco 13 is measured by the oven method.

[0043] Please also refer to Figures 1 to 3, the outer tube 10, the push rod 11 and the handle 14 can be made of metal materials such as stainless steel, aluminum alloy or zinc alloy. The outer tube 10, the push rod 11 and the accommodating tube 12 can be cylindrical in shape. The accommodating tube 12 includes a tube plug 121 and a tube body 122. Tube plugs 121 are provided at both ends of the tube body 122. The tube plug 121 can be made of rubber material. The tube body 122 can be made of glass. The right end of the outer tube 10 can include a cone 101 to facilitate insertion into the cigarette box 2, and the accommodating tube 12 is arranged at one end of the outer tube 10 close to the cone 101. When the tube plug 121 is removed, the tobacco 13 can be inserted into the tube body 122 from the left and right ends of the tube body 122 or poured out from the tube body 122. The two tube plugs 121 can plug the left and right ends of the tube body 122 respectively.

[0044] Please also refer to Figure 1 and Figure 2 The first air holes 1000 may be evenly arranged on the side wall of the outer tube 10 with reference to the central axis of the outer tube 10. The second air holes 1220 may be evenly arranged on the side wall of the tube body 122 with reference to the central axis of the tube body 122. The second air holes 1220 may face the first air holes 1000. The number of the second air holes 1220 may be multiple.

[0045] Please also refer to Figure 1 and Figure 2 Optionally, the tobacco moisture detection rod 1 further includes a push rod 11, which is inserted into the outer tube 10 to push the receiving tube 12 into the outer tube 10. The push rod 11 can abut against the receiving tube 12. The right end of the push rod 11 can abut against the left end of the receiving tube 12, that is, the push rod 11 can contact the receiving tube 12 but not be connected. The push rod 11 can be in a hollow tubular shape to reduce the weight of the push rod 11. When the push rod 11 is hollow, the sealing plug 15 can seal the left end of the push rod 11.

[0046] The dried shredded tobacco 13 refers to the shredded tobacco 13 that has been dried after absorbing moisture. The type of shredded tobacco 13 and the type of tobacco leaves in the cigarette box 2 can be the same.

[0047] The oven method is a basic method for determining moisture content, which includes: 1) weighing the tobacco 13 after absorbing moisture, and then placing it in an oven that reaches a preset temperature and drying it for a certain period of time; 2) weighing it again, and the difference between the tobacco 13 before and after drying is the mass of moisture in the drying; 3) recording the moisture content in the form of a percentage (i.e., water content).

[0048] Please also refer to Figures 1 to 3Since the water absorption rate of the shredded tobacco 13 is the same as that of the tobacco leaves in the cigarette box 2, the moisture value of the shredded tobacco 13 obtained by measuring the moisture of the tobacco leaves in the cigarette box 2 after the shredded tobacco 13 absorbs moisture through the first air holes 1000 and the second air holes 1220 is the same as that of the tobacco leaves in the cigarette box 2. Moreover, the oven method can directly measure the moisture of the shredded tobacco 13, and then directly obtain the moisture of the tobacco leaves. Compared with predicting the moisture of the tobacco leaves by measuring the moisture of the air in the cigarette box 2, the moisture measurement accuracy of the former is higher.

[0049] Please also refer to Figures 1 to 3 Since the receiving tube 12 is inserted into the outer tube 10, direct contact between the receiving tube 12 and the tobacco leaves can be avoided, and the wear of the tobacco leaves on the receiving tube 12 can be reduced. Using the outer tube 10 as a part of the tobacco moisture detection rod 1 can reduce the weight of the tobacco moisture detection rod 1 and improve the portability of the tobacco moisture detection rod 1. Because the tobacco shreds 13 and the tobacco leaves in the cigarette box 2 have similar or identical material properties, measuring the moisture of the tobacco leaves through the tobacco shreds 13 will not pollute the tobacco leaves in the cigarette box 2.

[0050] Please also refer to Figures 1 to 3 Optionally, the outer tube 10 includes a ventilation section 100, a plurality of first ventilation holes 1000, a plurality of first ventilation holes 1000 are arranged in the ventilation section 100, and the containing tube 12 is inserted in the ventilation section 100. The ventilation section 100 is inserted in the cigarette box 2. The plurality of first ventilation holes 1000 can be evenly arranged with reference to the central axis of the ventilation section 100. The ventilation section 100 can be in the shape of a circular tube, and the first ventilation holes 1000 can be densely distributed in the ventilation section 100. Arranging a plurality of first ventilation holes 1000 in the ventilation section 100 allows the tobacco 13 to fully and quickly absorb moisture in the air of the cigarette box 2. The containing tube 12 and the ventilation section 100 can be coaxially arranged. When testing the moisture content of tobacco leaves in the cigarette box 2, the ventilation section 100 and the containing tube 12 are completely embedded in the tobacco leaves in the cigarette box 2.

[0051] Please also refer to Figure 1 and Figure 2 Optionally, the length of the receiving tube 12 is equal to the length of the air permeable section 100, and the two ends of the receiving tube 12 are respectively flush with the two ends of the air permeable section 100. For example, the right end of the receiving tube 12 can be flush with the inner bottom of the outer tube 10, the right end of the receiving tube 12 can be flush with the right end of the air permeable section 100, and the left end of the receiving tube 12 can be flush with the left end of the air permeable section 100. In this way, the first air permeable hole 1000 and the second air permeable hole 1220 can be directly connected, preventing the second air permeable hole 1220 on the receiving tube 12 from being blocked by the side wall of the outer tube 10 because the length of the receiving tube 12 is greater than the air permeable section 100.

[0052] Please also refer to Figure 1 and Figure 2Optionally, the diameter of the first air hole 1000 is smaller than the diameter of the second air hole 1220. The first air hole 1000 and the second air hole 1220 may be round holes. The diameter of the first air hole 1000 is smaller than the diameter of the second air hole 1220 to prevent the tobacco 13 in the receiving tube 12 from falling out through the first air hole 1000.

[0053] Please also refer to Figure 1 and Figure 4 Optionally, the receiving tube 12 abuts against the inner bottom of the outer tube 10. The receiving tube 12 abuts against the inner bottom of the outer tube 10 to achieve positioning of the receiving tube 12 and prevent the position of the receiving tube 12 from axial movement. The right end of the receiving tube 12 can abut against the inner bottom of the outer tube 10. For example, the right pipe plug 121 can abut against the inner bottom of the outer tube 10.

[0054] Please also refer to Figure 1 and Figure 3 Optionally, the tobacco moisture detection rod 1 further includes a handle 14, which is connected to the outer tube 10. The handle 14 can be connected to the left end of the outer tube 10. The handle 14 and the outer tube 10 can be connected by welding, gluing or integral molding. The detection personnel can insert the outer tube 10 into the cigarette box 2 by holding the handle 14.

[0055] Please also refer to Figure 1 and Figure 3 Optionally, the handle 14 is tubular and is disposed perpendicular to the outer tube 10. The outer tube 10 can be connected to the middle position of the handle 14, that is, the handle 14 and the outer tube 10 can be disposed in a T-shape. The handle 14 is disposed perpendicular to the outer tube 10, so that the inspector can hold the handle 14 and insert the inspection rod into the cigarette box 2 along the length direction parallel to the outer tube 10, which is convenient for the inspector to hold and apply force. The tubular handle 14 can reduce the weight of the handle 14.

[0056] Please also refer to Figure 1 and Figure 2 Optionally, the tobacco leaf moisture detection rod 1 also includes a sealing plug 15, the outer tube 10 includes an opening 102, the push rod 11 and the accommodating tube 12 are inserted into the outer tube 10 via the opening 102, and the sealing plug 15 is sealed and connected to the opening 102. The outer tube 10 is open except for the opening 102 and the first air vent 1000, and the rest are sealed. The opening 102 can be located at the left end of the outer tube 10. The sealing plug 15 can be made of rubber, and the sealing plug 15 can be elastically deformed and interference fit with the opening 102. The right end of the sealing plug 15 can be against the left end of the push rod 11. The sealing plug 15 is provided to prevent moisture in the outside air from entering the tobacco 13 through the opening 102.

[0057] Please also refer to Figure 1 and Figure 2Optionally, the length direction of the outer tube 10, the length direction of the push rod 11, and the length direction of the receiving tube 12 are parallel to each other. The inner diameter of the outer tube 10 is equal to the outer diameter of the push rod 11, and the outer diameter of the push rod 11 is equal to the outer diameter of the receiving tube 12. When the inner diameter of the outer tube 10 is equal to the outer diameter of the push rod 11, and the push rod 11 is a solid rod or a hollow rod sealed at both ends, the push rod 11 can occupy the space in the outer tube 10 except the space occupied by the receiving tube 12, thereby reducing the air in the outer tube 10 from entering the receiving tube 12 and affecting the moisture measurement.

[0058] Please also refer to Figures 1 to 4 Before using the tobacco moisture detection rod 1, first put the dried shredded tobacco 13 into the tube body 122, plug the tube plugs 121 at both ends of the tube body 122, and then use the push rod 11 to push the plugged receiving tube 12 into the outer tube 10 from the opening 102 of the outer tube 10, and then plug the opening 102 with the sealing plug 15, and then hold the handle 14 to pierce the end of the outer tube 10 with the cone 101 into the cigarette box 2, and let it stand in the cigarette box 2 for a period of time (for example, 32 hours) to allow the shredded tobacco 13 to fully absorb moisture from the air in the cigarette box 2, and then take out the receiving tube 12, remove the tube plugs 121 at both ends of the tube body 122 and pour out the shredded tobacco 13 for drying. At this time, the reduced weight of the shredded tobacco 13 is the moisture content of the shredded tobacco 13, that is, the moisture content of the tobacco leaves in the cigarette box 2.

[0059] The above is a detailed introduction to the tobacco moisture detection rod provided in the embodiment of the present application. For those skilled in the art, according to the idea of ​​the embodiment of the present application, there will be some changes in the specific implementation method and application scope.
