[0023] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] 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.
[0026] like Figure 1 , Figure 2 and Figure 3 As shown, the disposable liquid sampler provided by the embodiment of the utility model is provided with a sampling chamber 100 and a testing chamber 200; the bottom of the sampling chamber 100 is separated from the bottom of the testing chamber 200; the top of the sampling chamber 100 is connected with the top of the testing chamber 200 through a guide port 400.
[0027] When sampling, hold the disposable liquid sampler by hand or place it flat so that the opening of the sampling cavity 100 faces upward, and the liquid sample can be directly injected into the bottom of the sampling cavity 100 until the liquid level reaches the required height. When testing, the disposable liquid sampler is tilted, and the liquid sample in the sampling cavity 100 will be poured into the test cavity 200 through the guide port 400. In this way, a certain amount of liquid sample can be poured into the test cavity 200 for standby use according to demand. Subsequently, a test paper is inserted into the test cavity 200 to dip in the liquid sample. The test paper will not cause the liquid sample in the sampling cavity 100 to be contaminated, thereby ensuring the cleanliness of the liquid sample in the sampling cavity 100 during the secondary test.
[0028] In the embodiment of the present invention, the top surface of the side wall of the sampling cavity 100 is flush with the top surface of the side wall of the testing cavity 200 , and the flow guide port 400 is configured as a gap disposed between the sampling cavity 100 and the testing cavity 200 .
[0029] When the liquid sample is injected into the sampling cavity 100, the side walls of the sampling cavity 100 and the side walls of the testing cavity 200 can block the liquid sample, thereby preventing the liquid sample from spilling out. When the disposable liquid sampler is tilted toward the testing cavity 200, the liquid in the sampling cavity 100 can flow into the testing cavity 200 through the gap. The disposable liquid sampler is not only easy to process and shape, but also can prevent the liquid sample from spilling during the test process.
[0030] like Figure 2 and Figure 3 As shown, the disposable liquid sampler has a liquid pouring nozzle 300 , and the liquid pouring nozzle 300 is arranged on the top of the side wall of the sampling chamber 100 .
[0031] Tilting the disposable liquid sampler can also make the liquid in the sampling cavity 100 flow toward the liquid pouring nozzle 300 , and then the liquid sample can be poured into a test tube or other container through the liquid pouring nozzle 300 .
[0032] It should be noted that the test cavity 200 and the pouring nozzle 300 are arranged at intervals along the circumference of the sampling cavity 100. By adjusting the pouring direction of the disposable liquid sampler, the liquid in the sampling cavity 100 can selectively flow into the test cavity 200 or the pouring nozzle 300. Preferably, the positions of the test cavity 200 and the pouring nozzle 300 are approximately 90 degrees relative to the circumferential interval of the sampling cavity 100, thereby avoiding overflow of the liquid sample when pouring the liquid sample into one of the test cavity 200 and the pouring nozzle 300.
[0033] like Figure 1 , Figure 2 and Figure 3 As shown, the disposable liquid sampler comprises: a cup body 001 and a handle 002 connected to the cup body 001 ; the cup body 001 has a sampling cavity 100 and a testing cavity 200 .
[0034] When sampling and testing, the handle 002 can be held for operation. The test cavity 200 is located on the side of the sampling cavity 100 away from the handle 002. The end of the handle 002 away from the sampling cavity 100 is lifted upward, so that the liquid sample in the sampling cavity 100 can be poured into the test cavity 200.
[0035] Furthermore, the sampling cavity 100 is located between the test cavity 200 and the handle 002, and the cup body 001 and the handle 002 are integrally formed by injection molding or hot pressing, etc., with low manufacturing cost, thereby reducing the cost of consumables for liquid sampling testing.
[0036] like Figure 1 As shown, a side wall of the cup body 001 connected to the handle 002 is provided with an outwardly protruding support portion 101 , and the support portion 101 extends to the bottom of the handle 002 .
[0037] Specifically, the side wall of the sampling cavity 100 close to the handle 002 protrudes outward, so that the inner wall forms a depression, and the outer wall protrudes outward to form a support portion 101. The support portion 101 can be supported on the bottom of the handle 002, which is equivalent to forming a reinforcing rib between the cup body 001 and the handle 002, thereby improving the stability of the handle 002 relative to the cup body 001.
[0038] Furthermore, the bottom surface of the cup body 001 is recessed upward to form a groove 102, and a convex ring 103 is formed which surrounds the groove 102 and protrudes downward. When the cup body 001 is placed on a table, the convex ring 103 contacts the table, reducing the contact area between the cup body 001 and the table. The contact between the convex ring 103 and the table improves the stability of the placement of the cup body 001.
[0039] like Figure 1 and Figure 2 As shown, the cross-sectional area of the sampling cavity 100 increases from bottom to top, thereby increasing the opening area at the top of the sampling cavity 100 to facilitate the injection of liquid samples.
[0040] 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.
