[0050] As shown in Figure 1 The sample sampling detection device provided by the present embodiment comprises a bottle cap component 100, a bottle body component 200, a base component 300 and a sampling component 400. The bottle body component 200 is internally provided with a separation cylinder 210 and a test paper 220. The test paper 220 is located outside the separation cylinder 210. The inner wall of the separation cylinder 210 is surrounded to form a cavity 211 for storing a test solution. The bottom opening of the separation cylinder 210 is provided with a sealing film 212, which is specifically an aluminum film. The side wall of the separation cylinder 210 and the sealing film 212 separate the test paper 220 and the test solution, so as to separate them dry and wet.

[0051] As shown in Figure 2 One end of the sampling component 400 is connected with the bottle cap component 100. The sampling component 400 is used for obtaining a sample, and the sampling component 400 can extend into the cavity 211.

[0052] The base member 300 is installed at the bottom of the bottle body member 200, and has a liquid storage cavity 320 into which one end of the test paper 220 in the bottle body member 200 extends.

[0053] The bottle cap member 100 is threadedly connected with the bottle body member 200. After the sampling member 400 obtains the sample, the bottle cap member 100 is screwed onto the bottle body member 200. The bottle cap member 100 is continuously screwed, and after the bottle cap member 100 is detached from the thread, the bottle cap member 100 can be moved downward relative to the bottle body member 200 to drive the sampling member 400 to pierce the sealing film 212, so that the test solution in the cavity 211 enters the liquid storage cavity 320 and contacts the test paper 220.

[0054] In addition, the outer surface of the bottle cap member 100 is also provided with anti-skid lines, which facilitates the user to screw the bottle cap member 100.

[0055] The sample sampling and detection device provided by the embodiment separates the test solution and the test paper 220 in the bottle body member 200 by using the separation cylinder 210 and the sealing film 212 at the bottom opening of the separation cylinder 210, so that dry and wet separation is achieved, and liquid leakage and seepage do not occur. After the bottle cap member 100 is screwed on the bottle mouth of the bottle body member 200 and is detached from the thread, the user drives the bottle cap member 100 to move downward relative to the bottle mouth of the bottle body member 200, so as to drive the sampling member connected with the bottle cap member 100 to pierce the sealing film 212, so that the test solution in the cavity 211 enters the liquid storage cavity 320 and fully contacts the test paper 220. The test paper 220 reacts and runs on the board to be detected. The overall device structure is simple and convenient to operate. The sample can be immediately diluted and detected after being collected, and the sample is not easy to be contaminated and decomposed, thereby solving the technical problems of complicated traditional fecal sample collection and detection evaluation operation, and easy sample contamination and decomposition in the prior art.

[0056] On the basis of the above embodiment, in an optional implementation, the bottle cap member 100 in the sample sampling and detection device provided by the embodiment is provided with a connecting cylinder 110. The connecting cylinder 110 is located at the middle position of the bottle cap member 100. One end of the sampling member 400 extends into the connecting cylinder 110, and the sampling member 400 is connected with the connecting cylinder 110. The outer wall of the connecting cylinder 110 is provided with an outer thread segment 111. The inner wall of the separation cylinder 210 is provided with an inner thread segment 213. The outer thread segment 111 is threadedly connected with the inner thread segment 213.

[0057] The connecting manner of the connecting cylinder 110 and the sampling member 400 can be various. The sampling member 400 can be detachably connected in the connecting cylinder 110 in a threaded connection manner, or the sampling member 400 can be detachably connected in the connecting cylinder 110 in a buckle protrusion manner.

[0058] As shown in Figure 3 optional embodiments, the top of the partitioning cylinder 210 passes through the end face of the bottle cap member 100; the partitioning cylinder 210 is provided with a lower limiting protrusion 214 passing through the end outer wall of the bottle cap member 100; the inner wall of the bottle cap member 100 is provided with an upper limiting protrusion 120; the upper limiting protrusion 120 and the lower limiting protrusion 214 can abut each other to limit the rotation of the bottle cap member 100 relative to the bottle body member 200.

[0059] It should be noted that the height dimension of the upper limiting protrusion 120 and the lower limiting protrusion 214 corresponds to the height dimension of the inner thread segment 213, which needs to be ensured that the upper limiting protrusion 120 and the lower limiting protrusion 214 can abut after the outer thread segment 111 is separated from the inner thread segment 213, so as to avoid the upper limiting protrusion 120 and the lower limiting protrusion 214 abutting too early, which causes the outer thread segment 111 unable to be separated from the inner thread segment 213. The abutting of the upper limiting protrusion 120 and the lower limiting protrusion 214 plays a role in reminding the user, and the user cannot continue to rotate the bottle cap member 100 when the upper limiting protrusion 120 and the lower limiting protrusion 214 abut, which reminds the user that the outer thread segment 111 has been separated from the inner thread segment 213, and the user can perform the pressing operation of the bottle cap member 100, so as to pierce the sealing film 212.

[0060] In order to fix the test paper 220 in the bottle body member 200, as shown in Figure 4 , Figure 5 , the sample sampling and testing device further comprises a fixing member 500; the fixing member 500 is arranged in the bottle body member 200, and the fixing member 500 is used for fixing the test paper 220.

[0061] Specifically, the fixing member 500 has a mounting groove 510 for the test paper 220 to extend into, and the groove wall of the mounting groove 510 is provided with a fixing nail 520, which can fix the test paper 220.

[0062] In order to fix the fixing member 500 in the bottle body member 200, the inner wall of the bottle body member 200 is extended to form a fixing rib 230, and the side surface of the fixing rib 230 is provided with a fixing groove 231; the outer side wall of the fixing member 500 is provided with a fixing protrusion 530, which extends into the fixing groove 231, so as to fix the fixing member 500 on the fixing rib 230, thereby fixing the test paper 220 in the bottle body member 200.

[0063] It should be noted that the fixing rib 230 is provided with two fixing ribs 230, and the two fixing ribs 230 are oppositely arranged, and the two fixing ribs 230 clamp the fixing member 500 therebetween.

[0064] AsFigure 6 As shown, in the optional embodiment, the base member 300 is provided with a liquid receiving cylinder 310, which is located at the middle of the base member 300, and the inner wall of the liquid receiving cylinder 310 is provided with a liquid receiving cavity 311. When the sampling member 400 pierces the sealing film 212, the test solution in the cavity 211 flows into the liquid receiving cavity 311. The inner wall of the base member 300 and the outer wall of the liquid receiving cylinder 310 form a liquid storage cavity 320. The liquid receiving cylinder 310 has a notch to communicate the liquid storage cavity 320 with the liquid receiving cavity 311. The test solution in the cavity 211 first flows into the liquid receiving cavity 311 and then flows into the liquid storage cavity 320 for running plate detection.

[0065] In the optional embodiment, the bottom of the liquid receiving cylinder 310 has an inclined flow guide surface 330, which is inclined towards the liquid storage cavity 320, so that the liquid in the liquid receiving cavity 311 is guided to flow into the liquid storage cavity 320, ensuring that the test solution can smoothly flow into the liquid storage cavity 320.

[0066] It should be noted that the connection between the base member 300 and the bottle body member 200 can be in various forms. For example, a buckle can be arranged at the bottom of the bottle body member 200, and a clamping groove can be arranged at the top of the base member 300. The buckle and the clamping groove are matched to realize the connection between the base member 300 and the bottle body member 200. Alternatively, the base member 300 can be welded on the bottle body member 200.

[0067] In the optional embodiment, the inner side of the partition cylinder 210 is inclined to form a connecting plate 215. The connecting plate 215 is inclined towards the sealing film 212. The inclined connecting plate 215 can guide the sampling member 400 to enter the cavity 211.

[0068] The end of the connecting plate 215 away from the inner wall of the partition cylinder 210 is connected with a sealing plate 216 arranged in a vertical direction. The sampling member 400 is provided with a sealing groove 410, and the sealing groove 410 is provided with a sealing member 600. The sealing member 600 is sealingly connected with the sealing plate 216, so as to seal the sampling member 400 and the sealing plate 216, preventing the test solution in the cavity 211 from flowing out from the gap between the sampling member 400 and the sealing plate 216.

[0069] The sampling member 400 is provided with a sampling groove 430 for obtaining a sample. The sampling groove 430 is located below the sealing groove 410, so that when the sampling member 400 is inserted into the cavity 211, the sample in the sampling groove 430 can fully contact the test solution in the cavity 211. The bottom end of the sampling member 400 is provided with a cutting knife 420 for piercing the sealing film 212, so as to ensure that the sampling member 400 can pierce the sealing film 212.

[0070] In conclusion, the sample sampling and detecting device provided by the utility model realizes dry and wet separation, increases the sealing property, prevents the test solution from volatilizing and prolongs the effective period by blocking the test paper 220 and the test solution in the cavity 211 by the sealing film 212 before use; in order to prevent misoperation, the sealing film 212 is punctured by adopting a two-step method, the bottle cap component 100 is first rotated and then is pressed down to puncture the sealing film 212, the test solution containing the sample flows to the receiving cavity through the break, is guided by the flow guide surface 330 and then enters the liquid storage cavity 320, the liquid in the liquid storage cavity 320 reacts with the test paper 220 and appears a color band, and detection is carried out.

[0071] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the utility model, and not to limit them; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
