[0034] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0035] Example 1:

[0036] like Figures 1-2The material of the first tank body 1 and the second tank body 2 is metal or black plastic to avoid light; the second tank body 2 and the third tank body 3 are sealed with a rotation angle of 360° or more.

[0037] The first tank body 1 is structured as follows: the upper part is open with an inner thread, used for rotating and sealingly connecting with the outer thread at the lower end of the second tank body 2; the first tank body 1 is 25-35 cm high and 10-30 cm in diameter, and is sealed to be light-proof.

[0038] The second tank body 2 is structured as follows: both the upper and lower tank openings are threaded, used for screwing into the first tank body 1 and the third tank body 3; the second tank body 2 is 10-15 cm high and 10-30 cm in diameter, and is sealed to be light-proof. The height of the second tank body 2 has multiple specifications; the inner thread at the upper end of a group of second tank bodies 2 is screwed into the outer thread at the lower end of the third tank body 3.

[0039] The inner part of the upper and lower tank openings of the second tank body 2 is installed with a layered closed partition plate; the layered closed partition plate 4 includes a lower partition plate 41, an upper partition plate 42, and a partition plate fixer 43; the lower partition plate 41 is a 270° sector structure with an opening and is 0.5-1 cm thick, can be fixed with the second tank body 2 through a thread, and is screwed in a depth of 0.5-1 cm; the upper partition plate 42 is a 180° sector structure and is 0.3-0.5 cm thick, and is fixed to the outer wall of the central shaft 5. The partition plate fixer 43 is fixed to the center of the lower partition plate 41, and the central shaft 5 penetrates the partition plate fixer 43 and rotates in cooperation therebetween; the second tank body 2 forms a tank body with both ends closed through the internal layered closed partition plate.

[0040] The third tank body 3 is structured as follows: the lower tank opening is threaded, used for screwing into and sealingly connecting with the second tank body 2; the top center is provided with a circular hole with a diameter of 0.4-0.6 cm for the upper end of the matching central shaft 5 to pass out; the third tank body 3 is 10-15 cm high and 10-30 cm in diameter. The third tank body 3 is a transparent visible tank body.

[0041] The central shaft 5 is 0.4-0.6 cm in diameter and 20-30 cm in length, which is the sum of the heights of the second tank body 2 and the third tank body 3. The central shaft 5 is an internal hollow tube, both ends and the middle 10-15 cm position are threaded, used for fixing with the upper partition plate 42.

[0042] After the above-mentioned first tank body 1, second tank body 2, third tank body 3, layered closed partition plate, and central shaft 5 are all installed, a three-layer structure is formed; after the circular hole at the top of the third tank body 3 is fixed with the central shaft 5, a plug (rubber plug) can be used for sealing.

[0043] When monitoring the respiratory metabolism and quality changes of internal samples, the rubber stopper can be removed, and a solid-phase microextractor can be inserted into the central shaft 5 to absorb the internal metabolic gases that evaporate from the primary tank 1 through the inner hole of the central shaft 5. The gas composition can then be analyzed by gas chromatography-mass spectrometry, thus enabling the monitoring of the respiratory metabolism of internal samples.

[0044] When taking internal samples, the tertiary tank 3 can be rotated 60-90°. At this time, one set of layered sealing baffles at the top of the secondary tank 2 closes, while the other set of layered sealing baffles at the bottom opens, allowing the sample in the primary tank 1 to be poured into the secondary tank 2. By continuing to rotate the tertiary tank 3 60-90°, one set of layered sealing baffles at the top of the secondary tank 2 opens, while the other set of layered sealing baffles at the bottom closes, allowing the sample in the secondary tank 2 to be poured into the tertiary tank 3. The sample can then be poured out by opening the top cover of the tertiary tank 3. This operation effectively prevents the sample in the primary tank 1 from being affected by light and also reduces the exchange of gases between the inside and outside. During this process, the tertiary tank 3 maintains a threaded fit with the secondary tank 2.

[0045] The third-stage tank 3 drives the lower partition plate 41 to rotate, thereby enabling the upper partition plate 42 to rotate relative to the lower partition plate 41. The rotation of the lower partition plate 42 opens or closes the opening of the upper partition plate 41.

[0046] Example 2: An improvement on Example 1, the difference being that, as follows... Figures 3-9 As shown:

[0047] The plug adopts a cylindrical plug rod 6 with a sealing layer on the outside. The shape of the plug rod 6 is adapted to the inner cavity of the central shaft 5 and rotates in a sealing fit. The upper end of the plug rod 6 is larger to prevent the plug rod 6 from falling completely into the central shaft 6. The plug rod 6 can be pulled out of the inner cavity of the central shaft 5.

[0048] Two sets of upper partition plates 42 are rotatably connected to the outer wall of the central shaft 5. A first elastic element 44 is connected between the lower partition plate 41 and the upper partition plate 42. Under normal conditions, the elastic force of the first elastic element 44 drives the upper partition plate 42 to rotate towards closing the opening of the lower partition plate 41. At the same time, the elastic force of the first elastic element 44 drives the upper partition plate 42 to move along the axis of the central shaft 5 and approach the lower partition plate 41, thereby tightly pressing the sealing ring between the upper partition plate 42 and the lower partition plate 41 and improving the sealing effect of the sealing ring.

[0049] like Figure 4As shown, the upper group of partition plate upper layer plate 42 side wall is provided with first clamping groove 421, and the first clamping groove 421 has multiple groups of annular array distribution around the axis line of the middle shaft rod 5, and the middle shaft rod 5 is provided with first through slot 51 corresponding to the position of the first clamping groove 421; the lower group of partition plate upper layer plate 42 side wall is provided with second clamping groove 422, and the middle shaft rod 5 is provided with second through slot 52 corresponding to the position of the second clamping groove 422, and the second clamping groove 422 has multiple groups of annular array distribution around the axis line of the middle shaft rod 5.

[0050] When the plug rod 6 is completely inserted into the inner cavity of the middle shaft rod 5, the plug rod 6 is provided with an upper local slot corresponding to the position of the first clamping groove 421 and the first through slot 51, and a first clamping rod 61 is hinged in the upper local slot, and a second elastic element 62 is connected between the middle part of the first clamping rod 61 and the inner side wall of the upper local slot, and the elastic force of the second elastic element 62 pushes the free end of the first clamping rod 61 to rotate outward; the plug rod 6 is provided with a lower local slot corresponding to the position of the second clamping groove 422 and the second through slot 52, and a second clamping rod 63 is hinged in the lower local slot, and a third elastic element 64 is connected between the middle part of the second clamping rod 63 and the inner side wall of the lower local slot, and the elastic force of the third elastic element 64 pushes the free end of the second clamping rod 63 to rotate outward.

[0051] As shown, Figure 6 After the plug rod 6 is completely inserted into the inner cavity of the middle shaft rod 5, the plug rod 6 is rotated counterclockwise relative to the middle shaft rod 5 until the free end of the first clamping rod 61 is aligned with the first through slot 51 of the middle shaft rod 5, and the free end of the first clamping rod 61 is inserted into the first through slot 51 under the pushing of the elastic force of the second elastic element 62, and rotating the middle shaft rod 5 makes the first through slot 51 align with the nearest first clamping groove 421, so that the free end of the first clamping rod 61 is inserted into the first clamping groove 421; at this time, the middle shaft rod 5, the plug rod 6 and the upper group of partition plate upper layer plate 42 are connected into one body through the first clamping rod 61, and then the middle shaft rod 5 / plug rod 6 can be rotated clockwise, and the upper group of partition plate upper layer plate 42 is rotated by the first clamping rod 61 to open the opening of the corresponding partition plate lower layer plate 41; at this time, the second clamping rod 63 on the plug rod 6 is in the state as shown in Figure 7 .

[0052] On the basis of Figure 6 , the plug rod 6 is rotated clockwise relative to the middle shaft rod 5 by 90°, so that the first clamping rod 61 is rotated relative to the plug rod 6 to make the free end of the first clamping rod 61 separate from the first clamping groove 421 and the first through slot 51, and in the normal state, the free end of the first clamping rod 61 abuts against the inner side wall of the middle shaft rod 5; the state at this time is as shown in Figure 8 .

[0053] Meanwhile, the plug rod 6 rotates clockwise relative to the middle shaft rod 5 until the free end of the second clamping rod 63 is aligned with the second through slot 52 of the middle shaft rod 5, and the free end of the second clamping rod 63 is inserted into the second through slot 52 under the elastic force of the third elastic member 64, the second through slot 52 is aligned with the nearest second clamping slot 422, so that the free end of the second clamping rod 63 is inserted into the second clamping slot 422; at this time, the middle shaft rod 5, the plug rod 6 and the upper layer plate 42 of the other group of partition plates below are connected into one body through the second clamping rod 63, and then the middle shaft rod 5 / plug rod 6 can be rotated clockwise to drive the upper layer plate 42 of the other group of partition plates below to rotate to open the opening of the lower layer plate 41 of the corresponding partition plate; the state at this time is as shown in Figure 9 .

[0054] In summary, driving the middle shaft rod 5 to rotate counterclockwise can drive the upper layer plate 42 of the group of partition plates above to rotate to open the opening of the lower layer plate 41 of the corresponding partition plate, and driving the middle shaft rod 5 to rotate clockwise can drive the upper layer plate 42 of the other group of partition plates below to rotate to open the opening of the lower layer plate 41 of the corresponding partition plate. The operation is simple, and only the forward and reverse rotation of the middle shaft rod 5 is needed to open or close the openings at the upper and lower ends of the two-stage tank body 2, and at the same time, only one group of partition plates can be opened at the same time, avoiding misoperation.

[0055] A rubber sleeve can be wrapped outside the first elastic member 44 to avoid the sample being clamped by the first elastic member 44.

[0056] Embodiment three: contains all the contents of embodiment two:

[0057] As shown in Figures 10-11 , the upper electrode brush 45 and the lower electrode brush 46 are respectively installed on the upper and lower sidewalls of the inner cavity of the first clamping slot 421 of the partition plate upper layer plate 42, all the upper electrode brushes 45 are connected in parallel, and all the lower electrode brushes 46 are connected in parallel; at the same time, the partition plate upper layer plate 42 is built-in with an electromagnet 47 and a battery, the upper electrode brush 45 and the lower electrode brush 46 are respectively connected with the positive and negative electrodes of the electromagnet 47, and under normal circumstances, as shown in Figure 10 , the upper electrode brush 45 and the lower electrode brush 46 fail to form a complete loop, so that the electromagnet 47 is not powered and has no magnetism.

[0058] When the free end of the first clamping rod 61 is inserted into any one of the first clamping slots 421, the upper electrode brush 45 and the lower electrode brush 46 are in contact with the conductive part 65 at the free end of the first clamping rod 61, so that the upper electrode brush 45 and the lower electrode brush 46 are connected to form a complete loop through the conductive part 65, and the battery supplies power to the electromagnet 47 to generate magnetism; the lower layer plate 41 of the upper partition plate is provided with a magnetic part, and the energized electromagnet 47 is magnetically repelled with the magnetic part, thereby driving the upper layer plate 42 of the partition plate to move slightly away from the lower layer plate 41 of the partition plate along the axis direction of the central shaft 5, so that the friction between the lower layer plate 41 of the partition plate and the upper layer plate 42 of the partition plate is small; at this time, the sealing ring on the upper layer plate 42 of the partition plate is still in contact with the lower layer plate 41 of the partition plate, but the pressure is smaller, reducing the friction.

[0059] After the free end of the first clamping rod 61 is pulled out of the first clamping slot 421, the electromagnet 47 is de-energized and loses magnetism, and under the elastic force of the corresponding first elastic member 44, the upper layer plate 42 of the partition plate moves along the axis direction of the central shaft 5 to approach and press the lower layer plate 41 of the partition plate, and the sealing ring is tightly sealed with good sealing effect.

[0060] The second clamping slot 422 of the lower layer plate 42 of the other group of partition plates is also provided with an upper electrode brush 45, a lower electrode brush 46, an electromagnet 47 and a battery, and has the same working principle as described above and will not be repeated here.

[0061] The above is only an embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation using the content of the present application specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the present application.
