DETAILED DESCRIPTION

[0026] The utility model is further described below in conjunction with the accompanying drawings:

[0027] The directional nouns involved in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application according to the visual orientation shown in the accompanying drawings. Unless otherwise clearly specified and limited, the terms "setting", "installation", "connection", etc. should be understood in a broad sense. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0028] like Figures 1 to 3 As shown, the sampler for edible oil quality detection includes a main body 100 with a accommodating chamber 101 defined inside, and one end of the accommodating chamber 101 is open, and the other end is provided with a baffle 102 with holes; the clamping device 300 is arranged on the side of the main body 100 provided with the baffle 102, and the end away from the main body 100 is drilled with a through hole 246; the liquid storage tank 400 is detachably embedded between the main body 100 and the clamping device 300, and a silicone block 421 is provided on the end facing the main body 100; the pre-negative pressure device 200 is arranged in the accommodating chamber 101, and consists of a vacuum tube assembly 210 and a drive assembly 220, and the two are connected by a cable 230, wherein one end of the vacuum tube assembly 210 passes through the hole of the baffle 102, and pierces from one side of the silicone block to the other side, and is connected with the liquid storage tank 400.

[0029] Optionally, the cable 230 includes but is not limited to ropes such as steel wire ropes and nylon ropes.

[0030] Optionally, a removable sealing cover 103 is provided at one end of the main body 100 away from the clamping device 300. In this way, the internal space of the main body 100 can be blocked by the sealing cover 103, so that the internal space of the main body 100 forms a certain degree of sealing, thereby reducing the damage caused by the entry of oil or other liquids into the main body 100, and effectively improving the service life of the sampler. At the same time, the removable sealing cover 103 can also maintain the internal components of the sampler through the installation position of the sealing cover 103 while ensuring the sealing of the internal space of the main body 100, so that the sampler can operate stably.

[0031] Optionally, the main body 100 has a battery 104 inside, and is connected to a portion of the pre-negative pressure device 200. In this way, the built-in battery 104 can provide the pre-negative pressure device 200 with the power required for operation at any time, so that the sampler can perform sampling without an external power supply, thereby improving the portability of the sampler.

[0032] Optionally, a charging port is provided on the side wall of the subject and is connected to the battery 104 .

[0033] Optionally, a multi-control switch 105 is provided on the side wall of the main body 100 for controlling the working state of the driving assembly 220 .

[0034] Optionally, a symmetrical fixing groove 106 is provided on the inner side wall of the main body 100 for fixing the driving assembly 220 .

[0035] like Figure 2 and Figure 3 As shown, a piston block 212 connected to one end of the cable 230 is provided in the tube body 211 of the vacuum tube assembly 210, and a return spring 213 is provided at one end of the piston block 212 facing the driving assembly 220 to abut against the piston block 212. In this way, driven by the driving assembly 220, the piston block 212 squeezes the return spring 213 during the process of moving toward the driving assembly 220. When the driving assembly 220 is reversed, the piston assembly can move to the initial position by relying on the return spring 213.

[0036] like Figure 4 As shown, at least one sealing ring 2123 is provided on the outer wall of the piston body 2121 of the piston block 212. In this way, the gap between the piston block and the inner wall of the tube body 211 can be filled by the sealing ring 2123, further improving the sealing performance of the tube body.

[0037] like Figure 4As shown, a connecting ring 2122 is provided at one end of the piston body 2121 facing the driving assembly 220 for connecting with the cable 230 .

[0038] like Figure 2 and Figure 3 As shown, a connector 240 is installed at one end of the tube body 211 away from the driving component 220, and one end of the connector 240 is connected to the tube body 211, one end passes through the silicone block 421 to communicate with the liquid storage tank 400, and one end protrudes out of the main body 100. In this way, the connector 240 is a multi-channel structure, and different channels are connected or protruded to different components to achieve different effects, thereby improving the working efficiency of the connector 240.

[0039] like Figure 5 As shown, the connector 240 includes a transverse tube 241 and a longitudinal tube 243 , and the two cross each other vertically, wherein the transverse tube 241 is provided with a flow cavity 242 for air to pass through, and the longitudinal tube 243 is provided with a sliding cavity 244 , and the flow cavity 242 is communicated with the sliding cavity 244 .

[0040] like Figure 5 As shown, a slidable pressing rod 245 is provided in the sliding cavity 244, and part of the pressing rod 245 protrudes from one end of the longitudinal tube 243 to the outside of the main body 100, wherein the pressing rod 245 is located in the sliding cavity 244 The side wall is drilled with a through hole 246 for connecting or closing the flow cavity 242.

[0041] It can be understood that when the vacuum tube assembly 210 is in a negative pressure state, without applying external force to the pressing rod 245, the through hole 246 and the circulation cavity 242 are in a misaligned state, so that the pressing rod 245 blocks the circulation cavity 242, so that the airflow cannot enter the tube body 211 from the circulation cavity 242. When an external force is applied to the pressing rod 245, the pressing rod 245 gradually moves downward, so that the through hole 246 on the pressing rod 245 gradually overlaps with the circulation cavity 242, and the tube body 211 is connected with the circulation cavity 242, so that the air in the liquid storage tank 400 can enter the tube body 211 through the circulation cavity 242.

[0042] Optionally, a top spring 247 and a bottom cover 248 are provided on the side of the pressing rod 245 away from the protruding end. In this way, the top spring 247 is arranged between the pressing rod 245 and the bottom cover 248, and the pressing rod 245 is moved toward the top spring 247 by applying pressure to the pressing rod 245, and the top spring 247 is compressed synchronously. When the external force is removed, the top spring 247 is released, and the pressing rod 245 moves in a direction away from the top spring 247 under the elasticity of the top spring 247, so that the through hole 246 on the side wall of the pressing rod 245 is misaligned with the flow cavity 242, thereby achieving the purpose of closing the flow cavity 242.

[0043] like Figure 5As shown, a detachable puncture tube 250 is installed at one end of the sampler connected to the liquid storage tank 400, and a plurality of connecting grooves 251 are provided on the side wall of the puncture tube 250. In this way, the air in the liquid storage tank 400 can enter the circulation cavity 242 through the plurality of connecting grooves 251, which not only increases the air permeability, but also avoids the puncture tube 250 from being able to work normally after the individual connecting grooves 251 are blocked, effectively improving the fault tolerance of the sampler and ensuring that the sampling work can be carried out normally.

[0044] like Figure 6 As shown, the driving assembly 220 includes a motor 223, a driving wheel 224, a driven wheel 225 and a winding roller 226. The driving wheel 224 is arranged on the power output end of the motor 223, and the winding roller 226 is arranged on one end of the driven wheel 225, and the driven wheel 225 is meshed with the driving wheel 224. In this way, under the cooperation of the motor 223, the driving wheel 224 and the driven wheel, the winding roller 226 can be driven to rotate, thereby achieving the purpose of tightening or releasing the cable 230.

[0045] Optionally, the driving assembly 220 further includes a front plate 221, a support rod 222 and a rear plate 227, wherein the support rod 222 is disposed between the front plate 221 and the rear plate 227. In this way, the motor 223, the driving wheel 224, the driven wheel 225 and the winding roller 226 are disposed between the front plate 221 and the rear plate 227, which not only plays a fixing role, but also plays a protective role. And by providing support at different positions between the front plate 221 and the rear plate 227 with a plurality of support rods 222, the displacement caused by the accidental falling of the sampler is effectively avoided.

[0046] Optionally, a mounting hole is drilled at one end of the outer wall of the winding roller 226 close to the driven wheel 225 or at one end away from the driven wheel 225 for connecting the cable 230. In this way, by fixing the cable 230 at a position away from the center of the winding roller 226, the cable 230 can be gradually moved away from the fixed point during the winding process. Compared with setting the fixed point in the middle of the winding roller 226, the cable 230 can be effectively reduced from stacking during the winding process, so that the winding process of the cable 230 can be carried out stably.

[0047] like Figure 7 As shown, the clamping assembly includes an elastic pull rod 310 and a clamping cap 320, wherein one end of the elastic pull rod 310 is symmetrically arranged on the outer side wall of the clamping cap 320, and the other end is connected to the outer side wall of the main body 100. In this way, the clamping cap 320 is always subjected to a pulling force in the direction of the main body 100 under the action of the elastic pull rod 310, and the farther the distance between the clamping cap 320 and the main body 100 is, the greater the pulling force of the elastic pull rod 310 is.

[0048] Optionally, a support plate 330 is provided between the symmetrically arranged elastic pull rods 310. In this way, the support plate 330 can limit the position of the liquid storage tank 400 embedded between the main body 100 and the clamping cap 320, thereby preventing the liquid storage tank 400 from being disengaged from between the main body 100 and the clamping cap 320, and ensuring that the liquid storage tank 400 can be stably clamped between the clamping cap 320 and the main body 100.

[0049] like Figure 8 As shown, the interior of the liquid storage tank 400 defines a liquid storage space 411 for storing liquid, one end of which is closed by a first sealing plate 420 and the other end is closed by a second sealing plate 430, wherein a silicone block 421 is provided on the first sealing plate 420 and a liquid collection tube 431 is provided on the second sealing plate 430.

[0050] Optionally, an extension tube 441 may be installed on the liquid collection tube 431. In this way, if the liquid level is low during the sampling process and sampling cannot be performed, the extension tube 441 may be connected to the liquid collection tube 431 to extend the sampling length.

[0051] Optionally, a cover 440 may be installed on the liquid collection tube 431. In this way, after the sampling work is completed, the liquid storage tank 400 can be sealed by installing the cover 440, thereby preventing the sample from leaking out of the liquid collection tube 431. At the same time, it also prevents foreign debris from entering the liquid storage tank 400 from the liquid collection tube 431, thereby preventing the debris from contaminating the sample.

[0052] Optionally, a scale 412 is further provided on the outer side wall of the tank body 410. In this way, it is convenient for the staff to intuitively obtain the sampling amount during the sampling process, and ensure that the sample amount obtained is sufficient.

[0053] It can be understood that when using this sampler to sample edible oil or other oil, first embed the end of the liquid storage tank 400 with the silicone block 421 in the direction of the main body 100 in the clamping device 300, and under the squeezing of the clamping cap 320, the puncture tube 250 pierces and passes through the silicone block 421 to protrude into the liquid storage tank 400. At this time, the multi-control switch 105 controls the operation of the drive assembly 220 to pull the piston block 212 in the tube body 211 toward the drive assembly 220, so that the inside of the tube body 211 is gradually in a vacuum state. When the piston block 212 moves to the preset position, the multi-control switch 105 automatically rebounds to the middle position and locks the drive assembly 220 to prevent the motor 223 from rotating. Choose whether to install the extension tube 441 for auxiliary sampling according to the actual sampling situation. Immerse the front end of the liquid collection tube 431 or the front end of the extension tube 441 in the oil to be sampled, apply external force to the pressing rod 245, so that the through hole 246 on the pressing rod 245 gradually overlaps with the connecting groove 251. Since the tube body 211 is in a vacuum state, after the through hole 246 overlaps with the connecting groove 251, the air in the liquid storage tank 400 generates suction under the vacuum effect, sucking the oil into the liquid storage tank 400, thereby achieving the purpose of sampling. When the sampling is completed, the liquid storage tank 400 is pushed away from the main body 100 to separate the puncture needle from the silicone block 421. The silicone block 421 will automatically close the hole produced by the puncture of the puncture needle under its own elasticity, so that the liquid storage tank 400 is in a closed state. Then, you only need to replace the new liquid storage tank 400 to carry out the next sampling work.

[0054] It is understandable that after multiple samplings, the vacuum pressure in the tube body 211 will gradually decrease. At this time, the multi-control switch 105 needs to be used to control the driving motor 223 to operate in the reverse direction to release the cable 230. After the piston block 212 loses the pulling force of the driving assembly 220, it will move in the direction away from the driving assembly 220 under the elastic action of the reset spring 213 until it is pushed to the initial position by the reset spring 213. After that, the pre-negative pressure device 200 can regain the vacuum state by simply repeating the above-mentioned operation.

[0055] Finally, although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
