Problems solved by technology

[0003] When testing some liquid foods, a sampling device is used to sample the liquid, but in order to improve the accuracy of the test, at present, the liquid is sampled at different depths. Inhalation, but the current method requires multiple insertions at different depths to sample the liquid during detection, and it is easy to shake the liquid during the insertion process, resulting in mixing of liquids between different depths, which affects the accuracy of detection

Embodiment 1

[0051] see Figure 1-Figure 10 As shown, a different depth sample sampling device for liquid food detection is provided, including a liquid storage device 100 and a guide device 200 arranged in the liquid storage device 100. The liquid storage device 100 includes a housing 110, and the housing 110 is arranged in sequence There are a sliding cavity 111, a liquid inlet cavity 112, a liquid storage cavity 113 and a negative pressure cavity 114. The bottom of the casing 110 is provided with a liquid inlet pipe 115 that communicates with the sliding cavity 111. The liquid inlet cavity 112, the liquid storage cavity Both the cavity 113 and the top of the negative pressure cavity 114 are provided with a cover plate 116, wherein the cover plate 116 at the top of the negative pressure cavity 114 is communicated with a through pipe 117, and a plurality of partitions 118 are arranged in the liquid storage cavity 113 to separate the The plate 118 can isolate the liquid storage cavity 113 ...

Embodiment 2

[0061] In order to quickly understand the distance between the shell 110 and the bottom of the container, the following improvements are made on the basis of Example 1:

[0062] see Figure 11-Figure 12 As shown, the side wall of the casing 110 is provided with a scale 230, the outer wall of the bottom end of the connecting rod 213 is provided with a transmission rod 231, and the other end of the transmission rod 231 is connected with an indicator plate 232, and the indicator plate 232 is sleeved on the casing 110. The outer wall, considering that when sampling some opaque liquids, people cannot observe the position of the casing 110 in the liquid. Therefore, when the casing 110 moves down, the casing 110 drives the scale 230 to move down. The distance between the casing 110 and the bottom of the container can be judged according to the position of the indicator plate 232 at the scale 230, so that it is convenient for people to observe the position of the casing 110 in the liq...

Embodiment 3

[0065] In order to facilitate the rapid drying of the outer wall of the housing 110, the following improvements are made on the basis of Example 1:

[0066] see Figure 13 As shown, the top of the sliding cavity 111 is provided with a sealing plate 240, the top of the sealing plate 240 is connected with a mounting pipe 241, the other end of the mounting pipe 241 is connected with a mounting block 242, and the mounting block 242 is sleeved on the top of the housing 110 In the outer wall, the installation block 242 is provided with a gas cavity, and the bottom of the installation block 242 is connected with a plurality of exhaust pipes 243. Considering that when sampling different liquids, the shell 110 needs to be cleaned before sampling. For this reason, When the piston block 211 moves, the gas in the sliding cavity 111 is pushed out, the gas enters the gas cavity in the installation block 242 through the installation pipe 241, and the gas in the gas cavity is discharged to th...

Abstract

The invention relates to a sampling device, in particular to a different-depth sampling device for liquid food detection. The sampling device comprises a liquid storage device and a guide device arranged in the liquid storage device, the liquid storage device comprises a shell, and a sliding cavity, a liquid inlet cavity, a liquid storage cavity and a negative pressure cavity are sequentially formed in the shell. The shell is pressed to enable the piston block to drive the first magnet block to move upwards, the first magnet block moves upwards to drive the baffle on the lower portion to move upwards through magnetic force, the liquid inlet in the bottom is forced to be closed, liquid at different depths can be sampled at a time, and the problems that according to an existing method, liquid needs to be sampled at different depths for multiple times during detection, and the sampling efficiency is high are solved. The liquid is easy to shake in the insertion process, so that the liquid at different depths is mixed, and the detection accuracy is influenced.

Description

technical field [0001] The present invention relates to a sampling device, in particular to a different depth sample sampling device for liquid food detection. Background technique [0002] With the continuous development of social economy, people's living standards and health awareness are constantly improving, people pay more and more attention to improving the quality of food, food plays an important role in people's life, work and study, and the quality of food is closely related to the people Interests and physical and mental health are issues of common concern to consumers and the whole society. Food testing plays an important technical supporting role in food product quality and safety evaluation, market supervision and product trade. The overall level plays an important role in safeguarding. [0003] When testing some liquid foods, a sampling device is used to sample the liquid. However, in order to improve the detection accuracy, the liquid is currently sampled at ...
