[0032] Embodiment two

[0033] Based on the improvement of embodiment one:

[0034] As shown in Figures 1 to 5As shown, the heating assembly 4 includes a heat-sealing switch 41 and a heating sleeve 42. The heating sleeve 42 is disposed inside the sample storage cylinder 1. The sample storage cylinder 1 is provided with a through hole. The upper end of the heat-sealing switch 41 extends out of the sample storage cylinder 1 through the through hole. The heating sleeve 42 and the heat-sealing switch 41 are electrically connected. The heating sleeve 42 is used to generate heat and conduct heat to the sample storage cylinder 1. The heat-sealing switch 41 is used to control the opening and closing of the heating sleeve 42.

[0035] After the sampling device is inserted into the ton bag, the heat sealing switch 41 is turned on. The heating sleeve 42 conducts heat to the sample storage cylinder 1. The heated sample storage cylinder 1 softens the inner bag of the lithium iron phosphate ton bag, making it adhesive and extensible. When the sampling device is pulled out of the ton bag, the outer surface of the inner bag of the ton bag will soften and bulge outward as the sampling device moves outward. At this time, use a clamping device such as a fixing clamp or pliers to clamp the bulging and softened inner bag of the ton bag. After the ton bag cools down, the clamping device can be removed to complete the sealing operation of the inner bag of the ton bag.

[0036] In another embodiment, such as Figure 2 As shown, the feeding switch assembly 3 includes a feeding button 33, a movable block 32, and a connecting rod 31. One end of the connecting rod 31 is movably connected to the self-spring sheet 2, and the other end of the connecting rod 31 is connected to the movable block 32. The lower end of the movable block 32, near the self-spring sheet 2, is connected to the connecting rod 31. The top of the movable block 32 is inclined, and the feeding button 33 is located above the inclined surface of the movable block 32. The bottom of the feeding button 33 is inclined. The top inclined surface of the movable block 32 and the bottom inclined surface of the feeding button 33 are slidably connected and cooperate with each other. The movable block 32 and the feeding button 33 are disposed inside the sample storage cylinder 1. The upper end of the feeding button 33 extends through the sample storage cylinder 1 and out of the sample storage cylinder 1. The feeding button 33 can move up and down for pressing, and the movable block 32 can move back and forth to drive the connecting rod 31. The movement of the connecting rod 31 drives the self-spring sheet 2 to close.

[0037] In order to allow the self-elastic sheet 2 to rotate inside the sample storage cylinder 1, a groove is provided at one end of the self-elastic sheet 2, and a rotating shaft is provided between the two sides of the groove. A rotating shaft ring 22 is rotatably connected to the rotating shaft, and the outer wall of the rotating shaft ring 22 is fixed to the inner wall of the sample storage cylinder 1.

[0038] Furthermore, in order to enable the movable block 32 to automatically rebound, a pressure spring 34 is provided on the side of the movable block 32 away from the connecting rod 31. The other end of the pressure spring 34 is fixedly installed inside the sample storage cylinder 1. The pressure spring 34 is used to press against the movable block 32 and restore the movable block 32 to its initial state.

[0039] In normal state, the discharging button 33 is popped up, the movable block 32 is right below the discharging button 33, and the self-popping piece 2 is in the closed state at this time; when sampling, the discharging button 33 is pressed, the discharging button 33 moves downward, the inclined surface of the discharging button 33 is in sliding connection with the inclined surface of the movable block 32, the movable block 32 is driven to move backward, the connecting rod 31 is driven to move backward at the same time, and thus the self-popping piece 2 is opened; when sampling is completed, the spring pushes the movable block 32 to move forward, and thus the self-popping piece 2 is closed and the discharging button 33 is driven to move upward to restore the initial state.

[0040] Further, as shown in Figure 4 、 Figure 5 , the inner wall of the self-popping piece 2 is provided with a movable buckle 21, the connecting rod 31 is provided with a connecting ring 35, the movable buckle 21 is sleeved with the connecting ring 35, and the connecting rod 31 and the self-popping piece 2 are movably connected.

[0041] Further, in order to protect the safety of the sampler, the handle 5 is arranged at the end of the sampling cylinder body 1 away from the conical hole 11, and the handle 5 can effectively avoid scalding the sampler's hand by the heated sampling cylinder body 1.

[0042] In another embodiment, the sampling cylinder body 1 is made of ceramic material, which can effectively prevent the introduction of magnetic substances and avoid the pollution of lithium iron phosphate powder.

[0043] Working principle:

[0044] As shown in Figures 1 to 5 , when sampling, the sharp part of the conical hole 11 pierces the lithium iron phosphate ton bag, the sampling device is inserted into the lithium iron phosphate ton bag, the discharging button 33 is pressed, the discharging button 33 moves downward, the inclined surface of the discharging button 33 is in sliding connection with the inclined surface of the movable block 32, the movable block 32 is driven to move backward, the connecting rod 31 is driven to move backward at the same time, and the self-popping piece 2 is opened under the action of the material thrust; when the sampling device is inserted into the ton bag, the sampling sample enters the sampling cavity 12 to complete sampling;

[0045] When sampling is completed, the discharging button 33 is released, the pressure spring 34 pushes the movable block 32 to move forward, and thus the self-popping piece 2 is closed and the discharging button 33 is driven to move upward to restore the initial state, and the self-popping piece 2 is closed under the compression of the sample material, the sampled sample material is left in the sampling cavity 12, and at this time the sampling device can be pulled out;

[0046] When the sampling device is pulled out from the ton bag, the hot switch 41 is pressed to heat the heating sleeve 42, so as to heat the sample storage cylinder 1. The outer bag of the ton bag is softened and has adhesion and ductility by the heated sample storage cylinder 1, and the outer bag of the ton bag is bulged outwards at the opening of the outer bag as the sampling device moves outwards. At this time, the outer bag of the ton bag is clamped by using a clamping device such as a fixed clamp or a clamp. After the ton bag is cooled, the clamping device can be removed, and the sealing operation of the inner bag of the ton bag is completed.

[0047] When the sample is poured out, the discharge button 33 is pressed again, and the spring plate 2 is opened, so that the sample can be poured out.

[0048] However, the working principle and wiring method of the hot switch 41 are common, which are well known to those skilled in the art, and belong to conventional means or common knowledge. Therefore, the skilled in the art can make any selection according to the needs or convenience, which will not be described here.
