[0031] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Physical quantities in formulas, unless otherwise specified, should be understood as basic quantities of the International System of Units (SI) base units, or derived quantities derived from basic quantities through mathematical operations such as multiplication, division, differentiation, or integration.
[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0034] like Figure 1 As shown, the instant detection device provided in this embodiment of the present invention includes: a test chamber shell 001, a test strip 002, a reservoir 003, a sampling element 004, and a pressure cap 005; the sampling element 004 is connected to one end of the reservoir 003, and the pressure cap 005 is movably connected to the other end of the reservoir 003; the test strip 002 is installed inside the test chamber shell 001, and the reservoir 003 is detachably connected to the test chamber shell 001; with the reservoir 003 connected to the test chamber shell 001, the sampling element 004 is inserted into the test chamber shell 001; the reservoir 003 has an opening 301 opposite to the inner cavity of the test chamber shell 001, and the opening 301 is closed by a sealing membrane 302; the pressure cap 005 is provided with a membrane-piercing part 501 for piercing the sealing membrane 302.
[0035] In this embodiment, the reservoir 003 contains a buffer solution, which is sealed inside the reservoir 003 to prevent leakage during storage or transportation of the detection device. Furthermore, the sampling element 004 is integrated with the reservoir 003. Even when the reservoir 003 is separated from the test chamber housing 001, the reservoir 003 and the cap 005 can be operated to take samples along with the sampling element 004. After sampling, the reservoir 003 is connected to the test chamber housing 001, and the sampling element 004 is inserted into the test chamber housing 001. Then, the cap 005 is pushed, piercing the sealing membrane 302 through the membrane-breaking part 501. The buffer solution inside the reservoir 003 can be released into the test chamber housing 001 through the opening 301. The buffer solution can wash the sample on the sampling element 004, mixing to form a sample solution, which can then contact the test strip 002, thereby completing the test reaction.
[0036] It should be noted that the test chamber shell 001 can be made of transparent material or have a transparent part so as to observe the final color development of the test strip 002, thus eliminating the need to separate the reservoir 003 and the test chamber shell 001 again to observe the test results and avoiding leakage of the sample solution after the test.
[0037] like Figure 1 and Figure 2 As shown in this embodiment of the utility model, a sealing element 006 is provided on the cap 005. The sealing element 006 is slidably fitted on the inner wall of the reservoir 003. The sealing element 006 enhances the sealing performance at the joint between the cap 005 and the reservoir 003, reducing the risk of buffer solution leakage from the reservoir 003.
[0038] Furthermore, the cap 005 is provided with a limiting protrusion ring 502, and the cap 005 is slidably inserted into the reservoir 003 along the axial direction of the limiting protrusion ring 502; the inner wall of the reservoir 003 is provided with a limiting rib 303 corresponding to the limiting protrusion ring 502; in the initial state, the limiting protrusion ring 502 and the limiting rib 303 are spaced apart, and the membrane breaking part 501 and the sealing membrane 302 are spaced apart; after the cap 005 is pushed, the limiting protrusion ring 502 abuts against the limiting rib 303, and the membrane breaking part 501 punctures the sealing membrane 302. The abutment of the limiting protrusion ring 502 against the limiting rib 303 can generate a stopping effect on the cap 005. The operator can sense that the cap 005 has been pressed into place by pushing and pressing the cap 005, and thus know that the sealing membrane 302 has been punctured by the membrane breaking part 501.
[0039] like Figure 1 and Figure 3 As shown, the sampling component 004 includes: a rod portion 401 and a connector portion 402 connecting the rod portion 401; the connector portion 402 is connected to the reservoir 003 by a threaded connection.
[0040] The connector 402 has a perforated structure so that the buffer solution can enter the test chamber shell 001 through the perforated structure after the sealing membrane 302 is punctured.
[0041] In addition, the surface of the rod 401 is provided with a sampling groove, or the rod 401 is fitted with a water-absorbing component to increase the amount of sample that the rod 401 can pick up.
[0042] In an optional embodiment, the liquid reservoir 003 and the test chamber housing 001 are connected by a threaded connection, which not only ensures a stable connection but also seals the connection to prevent leakage of sample liquid after testing.
[0043] In other alternative embodiments, the reservoir 003 and the test chamber housing 001 can be interference-fitted or snap-fitted together, which can also achieve the integrated combination of the reservoir 003 and the test chamber housing 001.
[0044] like Figure 1 and Figure 4 As shown, a test strip holder 007 is installed inside the test chamber shell 001. The test strip 002 is connected to the test strip holder 007. The test strip holder 007 supports the test strip 002, which not only improves the stability of the test strip 002, but also prevents the test strip 002 from shifting inside the test chamber shell 001 and affecting the observation of its color development results.
[0045] In an optional embodiment, the test strip holder 007 includes a tube that houses the sampling element 004. The tube has a notch at one end away from the reservoir 003, through which the sample liquid is released to the outside of the test strip holder 007 and comes into contact with the test strip 002. This improves the accuracy of the test by ensuring that the sample and buffer solution are fully mixed inside the test strip holder 007.
[0046] In addition, the test strip 002 is connected to the outside of the tube and extends along the axial direction of the tube, which allows the test strip 002 to gradually complete the color reaction from the end away from the reservoir 003 to the end closer to the reservoir 003, making it easier to observe the test results.
[0047] Furthermore, the outer surface of the fitting is provided with a mounting groove 701, and the test strip 002 is installed in the mounting groove 701. The inner side of the mounting groove 701 is provided with a limiting part 702 for fixing the test strip 002. The limiting part 702 can be configured as a limiting protrusion or a limiting pin, etc. The test strip 002 is constrained by the limiting part 702, thereby preventing the test strip 002 from loosening and falling off relative to the test strip holder 007.
[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
