[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, the liquid sampling device provided by the embodiment of the utility model includes: a cup body 100, a cup cover 200 and a stopper 300; the cup cover 200 is provided with a test hole 201, and the cup cover 200 covers the cup body 100; the stopper 300 is movably connected to the cup cover 200, and the stopper 300 can be opened and closed to cover the test hole 201.

[0028] Before the cup cover 200 covers the cup body 100, the liquid sample can be injected into the cup body 100 through the top opening of the cup body 100, and then the cup cover 200 is closed to seal the liquid sample in the cup body 100. During testing, the stopper 300 can be operated to move relative to the cup cover 200, so that the stopper 300 is removed from the test hole 201. At this time, the test plate or test strip can be inserted into the cup body 100 through the test hole 201 for testing to avoid spilling the liquid sample. After the test, the test plate or test strip can be completely inserted into the test hole 201, and then the stopper 300 is covered on the test hole 201 to prevent the external environment from being contaminated.

[0029] It should be noted that the plug 300 can be hinged or slidably connected to the cup cover 200, so that not only the opening and closing of the test hole 201 can be achieved, but also the plug 300 can be prevented from falling off the cup cover 200, which is more convenient for sampling and testing operations.

[0030] In the embodiment of the utility model, the cup cover 200 is provided with a liner portion 202 coaxially arranged with the test hole 201 , and the liner portion 202 is inserted into the cup body 100 .

[0031] During the test, the test plate or test strip can be inserted into the cup body 100 along the liner portion 202, which can not only dip the liquid sample in the cup body 100, but also scrape off the excess liquid sample on the surface of the test plate or test strip through the side wall of the liner portion 202, thereby avoiding liquid dripping when taking out the test plate or test strip and preventing the external environment from being contaminated.

[0032] In addition, when the cup body 100 is held by hand when the stopper 300 is opened, the liquid sample in the cup body 100 is not easily splashed out of the test hole 201 through the liner portion 202 , thereby reducing the risk of external environment being contaminated.

[0033] like Figure 2 As shown, a maximum liquid level scale 103 is provided on the side wall of the cup body 100 to mark the amount of liquid sample that the cup body 100 can contain, so as to prevent the operator from taking excessive samples.

[0034] In addition, the maximum liquid level scale 103 is located at a height lower than the bottom of the liner portion 202 , thereby preventing the liner portion 202 from being contaminated by the liquid sample in the cup body 100 and reducing the risk of the liquid sample splashing out of the test hole 201 through the liner portion 202 .

[0035] like Figure 1 and Figure 2 As shown, the cup cover 200 has a sleeve portion 203 , and the sleeve portion 203 is sleeved on the cup body 100 .

[0036] In an optional embodiment, the sleeve portion 203 may be interference-fitted to the outer wall of the cup body 100 , thereby ensuring that the opening at the top of the cup body 100 is sealed.

[0037] In this embodiment, a first snap portion 204 is provided on the inner side of the sleeve portion 203, and the cup body 100 is provided with a second snap portion 101 adapted to the first snap portion 204. The second snap portion 101 is connected with the first snap portion 204 so that the cup cover 200 can be firmly closed relative to the cup body 100.

[0038] like Figure 2 As shown, the outer wall of the cup body 100 is provided with a convex ring 102, and the convex ring 102 is located below the bushing portion 203. The convex ring 102 can improve the structural stability of the cup body 100, thereby ensuring that the cross-sectional shape of the cup body 100 is stable.

[0039] When the cup cover 200 is covered on the cup body 100 , there is a gap between the protruding ring 102 and the bushing 203 , so as to prevent the protruding ring 102 from hindering the cup cover 200 from covering the cup body 100 .

[0040] like Figure 1 As shown, the plug 300 includes: a cover portion 301 and a convex plug 302 connected to the cover portion 301 ; the cover portion 301 is hinged to the cup cover 200 , and the convex plug 302 is detachably inserted into the test hole 201 .

[0041] The convex plug 302 can be interference fit in the test hole 201, thereby ensuring that the test hole 201 is completely sealed. In addition, the end of the convex plug 302 away from the cover plate portion 301 can be configured as a cone, so that the convex plug 302 is accurately aligned when inserted into the test hole 201.

[0042] like Figure 1 As shown, the cup cover 200 is provided with a limiting groove 205 , and the cover plate portion 301 is located in the limiting groove 205 , which can ensure that the cover plate portion 301 is accurately aligned with the cup cover 200 , thereby improving the stability of the plug 300 covering the test hole 201 .

[0043] like Figure 1 , Figure 2 and Figure 3 As shown, the cover portion 301 extends to the outside of the upper surface of the cup cover 200 so that fingers can touch the cover portion 301 when the plug 300 is closed, and the convex plug 302 can be pulled out of the test hole 201 by lifting the cover portion 301 upwards.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
