[0038] Specifically, the sample injection assembly 32 in the embodiment includes an upper cover 321, a support plate 322, and a sample injection body 323, and is provided with a sample injection port 301. Optionally, the upper cover 321 is connected to the connecting column 31 at the top, and in the embodiment, the upper cover 321 is provided in an arc shape, and the outer diameter of the upper cover 321 is greater than or equal to the outer diameter of the cover 34, so that when the cover 34 moves upward in the sample injection assembly 32, the upper cover 321 can limit the cover 34 and limit the upward movement range of the cover 34, so as to avoid the cover 34 from being separated from the sample injection assembly 32, and the arc-shaped top of the upper cover 321 can reduce the resistance of the device moving in the liquid. Further, the support plate 322 is located between the upper cover 321 and the sample injection body 323, and a plurality of support plates 322 are separated to form a plurality of sample injection ports 301, and the liquid can enter the inside of the sample injection assembly 32 through the sample injection port 301. For example, in the embodiment, three support plates 322 are provided, and three sample injection ports 301 are provided between the upper cover 321 and the sample injection body 323, so that the liquid can enter the sample injection body 323 from the three sample injection ports 301.

Optionally, a silica gel sleeve meeting the food safety requirements can be provided in the sample injection body 323, so that the liquid can enter the sample cup 40 through the inside of the silica gel sleeve to ensure the sampling quality. Further, the cover 34 can cover or open the silica gel sleeve.

[0039] Optionally, the movable assembly includes an upper fixing member 331, a guide column 332, a lower fixing member 333, and a spring 334. Optionally, in the embodiment, the cover 34 is sleeved on the outside of the guide column 332 and can cover or open the sample injection body 323, and the upper fixing member 331 is arranged above the guide column 332 and is used for connecting the steel wire 22, so that when the pressing part 12 is rotated and pressed, the guide column 332 can drive the cover 34 to move upward or downward in the sample injection assembly 32 under the connection of the steel wire 22 and the upper fixing member 331. Further, the lower fixing member 333 is arranged below the guide column 332, and the spring 334 is sleeved on the outside of the guide column 332 and located between the sample injection body 323 and the lower fixing member 333, so as to facilitate the falling of the cover 34. For example, a pressing platform is arranged at the center of the bottom of the sample injection body 323 to limit the position of the spring 334, or a support platform can be sleeved on the guide column 332 in other embodiments and abut against the bottom of the sample injection body 323, so as to ensure that the spring 334 can be compressed when the guide column 332 moves upward, and facilitate the subsequent recovery of the position of the movable assembly, so that the cover 34 can timely close the sample cup 40. Accordingly, in other embodiments, other ways can also be adopted to realize the effective compression of the spring 334, which will not be described here.

[0040] Combination Figure 4 and Figure 5 As shown, specifically, when the pressure handle 10 is not operated and the injector 30 is in a closed state, the cap 34 seals the injection body 323, at which time the sample cup 40 is isolated from the external environment, and the liquid no longer enters the sample cup 40; when the pressure handle 10 is operated and the injector 30 is in an open state, the movable component moves upward relative to the injection component 32 under the action of the steel wire 22, the spring 334 is compressed, the cap 34 opens the injection body 323, and the sample cup 40 is connected to the external environment, so that the liquid can enter the sample cup 40 through the injection port 301, thereby achieving the sampling effect of fixed point and quantitative sampling.

[0041] Optionally, the sample cup 40 can be provided in various types, such as 450ml, 600ml, and 800ml. More types can also be provided in other embodiments without limitation. Specifically, the bottle mouth of the sample cup 40 is provided with an internal thread, and the outer side of the injection body 323 is provided with an external thread, thereby enabling a stable connection between the sample cup 40 and the injection body 323 through the threaded connection.

[0042] Working process: The sampler holds the transmission rod 20 and the pressure handle 10, places the injector 30 and sample cup 40 in the predetermined position, and then reads the temperature of the sample at the predetermined position through the thermometer 21 on the transmission rod 20. Then, the pressure handle 10 is operated, so that the cap 34 in the injector 30 is lifted upward under the linkage of the steel wire 22, thereby opening the injection body 323, so that the sample can enter the interior of the injection body 323 through the injection port 301, and then enter the sample cup 40. When the sample cup 40 is full or reaches the predetermined weight, the pressure handle 10 is released, the cap 34 closes the injection body 323, and no more sample enters the sample cup 40, thus completing the fixed-point sampling. Finally, the sealed sample cup 40 is taken out, and the internal sample is poured into the physicochemical bottle and the retention bottle, completing the overall sampling work. In this embodiment, all parts of the multifunctional portable sampler can be connected by screws, which makes it easy to carry and assemble, and facilitates classification and storage. At the same time, the sampling process can be controlled by the open and closed state of the sampler 30, and fixed-point and quantitative sampling can be performed at any time. With the display screen in the thermometer 21, the temperature of the sample can also be detected and observed in a timely manner, thereby improving the detection efficiency.
