[0049] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0050] like Figure 1 、 Figure 2 、 Figure 6 As shown, the split sampling and testing device provided by the utility model includes: a sampling component 1 and a testing component 2; the sampling component 1 includes a sampling bottle 11, a sampling bottle cap 12 and a sampling head 13; the sampling bottle cap 12 is connected to the open end of the sampling bottle 11, specifically, the end of the sampling bottle 11 has an opening, an external thread section 111 is provided at the open end of the sampling bottle 11, and an internal thread section 121 is provided on the inner wall of the sampling bottle cap 12, the external thread section 111 and the internal thread section 121 are threadedly connected to realize a detachable connection between the sampling bottle cap 12 and the sampling bottle 11.

[0051] The sampling bottle cap 12 has a connecting hole 122 that is set through it. Specifically, a connecting tube structure with a hollow middle part is set in the middle position of the sampling bottle cap 12. The middle part of the connecting tube is hollow to form a connecting hole 122. The sampling head 13 is set in the connecting hole 122. One end of the sampling head 13 extends into the sampling bottle 11. The sampling head 13 is used to obtain samples. The sampling head 13 can be replaced according to actual needs to test different samples, which solves the problem of single functionality of most products on the market.

[0052] The sampling head 13 is configured to be capable of telescopic movement relative to the sampling bottle 11 . The sampling head 13 has a sampling position and a testing position, and moves between the sampling position and the testing position through the telescopic movement of the sampling head 13 .

[0053] The test assembly 2 has a liquid storage cavity, and the test assembly 2 is used for inserting the sampling head 13. The sampling head 13 inserted into the test assembly 2 is retracted into the connecting hole 122 to connect the sampling bottle 11, the connecting hole 122 and the liquid storage cavity.

[0054] Buffer solution is stored in the sampling bottle 11; when the sampling head 13 is in the sampling position, one end of the sampling head 13 extends into the sampling bottle 11 to block the opening of the sampling bottle 11 to prevent the buffer solution in the sampling bottle 11 from flowing out, and the other end of the sampling head 13 extends out of the connecting hole 122, and the sampling head 13 performs the sampling operation; when the sampling head 13 is in the testing position, the sampling head 13 retracts into the connecting hole 122, and the buffer solution in the sampling bottle 11 enters the liquid storage cavity after passing through the sampling head 13, and the test can be carried out.

[0055] The 2nd embodiment of the present invention is characterized in that the 2nd embodiment of the present invention is characterized in that the 2nd embodiment of the present invention is characterized in that the 2nd embodiment of the present invention is characterized in that the 2nd embodiment of the present invention is characterized in that the 2nd embodiment of the present invention is characterized in that the 2nd embodiment of the present invention is characterized in that the 2nd embodiment of the present invention is characterized in that the 2nd embodiment of the present invention is characterized in that the 2nd embodiment of the present invention is characterized in that the 2nd embodiment of the present invention is characterized in that the 2nd embodiment of the present invention is characterized in that the 2nd embodiment of the present invention is characterized in that the 2nd embodiment of the present invention is characterized in that

[0056] Regarding the structure and shape of the sampling component 1, specifically:

[0057] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, a sampling section 131 is provided at the end of the sampling head 13 away from the sampling bottle 11. The sampling section 131 can obtain samples. The samples can be nasal, oral, saliva, urine, blood, feces and other types. Different types of sampling sections 131 are selected according to the types of samples obtained. The sampling head 13 has a solution flow channel 133. The solution flow channel 133 is closer to the sampling bottle 11 than the sampling section 131. When the sampling head 13 is in the testing position, the solution flow channel 133 is located in the sampling bottle 11. The buffer solution in the sampling bottle 11 enters the liquid storage cavity after contacting the sampling head 13 through the solution flow channel 133. When the sampling head 13 is in the sampling position, the solution flow channel 133 is located in the connecting hole 122. Since the sampling head 13 blocks the opening of the sampling bottle 11, the buffer solution in the sampling bottle 11 cannot flow out.

[0058] In an optional embodiment, the sampling head 13 extends into one end of the sampling bottle 11 and is provided with a mounting groove 132, and a sealing element 14 is provided in the mounting groove 132. The sealing element 14 can be specifically configured as a sealing ring. When the sampling head 13 is in the sampling position, the sealing element 14 contacts the open end of the sampling bottle 11 to seal the sampling bottle 11, thereby preventing the buffer solution in the sampling bottle 11 from flowing out.

[0059] In an optional embodiment, the sampling assembly 1 further includes a sampling protection member 15 ; the sampling protection member 15 can cover the sampling head 13 to protect the sampling head 13 .

[0060] Regarding the structure and shape of the test component 2, specifically:

[0061] like Figure 1 、 Figure 2 、 Figure 5 As shown, the test assembly 2 includes a test base 21, a test cavity 22 and a test element 23; the test cavity 22 is a shell structure, and a liquid storage cavity is formed inside. The bottom of the test cavity 22 has an opening, and the test base 21 is installed in the test cavity 22 through the opening, and the test base 21 is welded or snap-connected to the test cavity 22 to fix the test base 21 in the liquid storage cavity in the test cavity 22; the test cavity 22 has a placement hole 222 for inserting the sampling head 13. When the sampling is completed and testing is required, the sampling head 13 is inserted into the placement hole 222. After the insertion is completed, the liquid flows into the test cavity 22, and the test element 23 is installed in the liquid storage cavity. The test element 23 is specifically configured as a detection plate. The liquid in the liquid storage cavity contacts the test element 23 to perform a running board test.

[0062] The test base 21 has a top return structure 211, a guide inclined surface 212 and a solution quantitative groove 213; the guide inclined surface 212 protrudes to form a top return structure 211, and the top return structure 211 protrudes toward the placement hole 222. When the sampling head 13 is inserted into the placement hole 222, the top return structure 211 abuts against the sampling head 13. As the sampling head 13 is inserted into the placement hole 222, the top return structure 211 supports the sampling head 13, and the sampling head 13 is retracted into the connecting hole 122, releasing the sampling head 13 from blocking the opening of the sampling bottle 11. The buffer solution in the sampling bottle 11 enters the liquid storage cavity after contacting the sampling section 131 through the solution flow channel 133. Since the guide inclined surface 212 is inclined toward the solution quantitative groove 213, the liquid can be introduced into the solution quantitative groove 213. The solution quantitative groove 213 is used to obtain a quantitative solution for testing the running board, ensuring that the solution used for the test is sufficient and not excessive.

[0063] In an optional embodiment, the test base 21 has a solution storage tank 214, and there is a tank wall between the solution storage tank 214 and the solution quantitative tank 213. The excess liquid in the solution quantitative tank 213 can pass over the tank wall and enter the solution storage tank 214. The solution storage tank 214 serves to store excess samples.

[0064] In an optional embodiment, the test chamber 22 has a fixed cavity 221, which is vertically arranged. A fixed bracket 24 is mounted in the fixed cavity 221. The fixed bracket 24 is connected to the test element 23 so that the test element 23 is vertically arranged, and the test end of the test element 23 is placed in the solution quantitative tank 213 to ensure that the test end of the test element 23 is fully immersed in the sample liquid in the solution quantitative tank 213.

[0065] In an optional embodiment, the test cavity 22 has an observation window 223 . It should be noted that the observation window 223 is located at the result display end of the test element 23 , ensuring that the user can observe the test results of the test element 23 through the observation window 223 .

[0066] The split sampling and testing device provided in this embodiment has a split design that can perform sampling and testing separately, making it easier to control the test time. Different samples can be obtained by selecting different sampling heads 13, achieving multi-purpose functions and being able to test different samples, thereby solving the problem of single functionality of most products on the market. Through the extension and retraction of the sampling head 13, the space of the product is effectively utilized, and a perfect connection between sealing and opening is achieved. Most parts are shared by different samples, thereby achieving the purpose of energy conservation and emission reduction.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
