Moreover, different conveying hoses 26 and connection hoses 27 can be replaced according to the variety of the sample to achieve the conveyance of various liquid samples, including viscous, corrosive, and particulate-containing samples, with a wide range of applications. In addition, the structure of this device is relatively simple, easy to maintain and clean, reducing the use cost and maintenance difficulty of the equipment.

[0026] Embodiment 2

[0027] As Figures 1-4 shown in the figure, the present utility model provides a technical solution: the conveying device 2 includes a device housing 21. An installation cavity 22 is opened inside the device housing 21. A rotating disk 23 is provided inside the installation cavity 22. Extrusion corners 24 are provided at the four corners of the rotating disk 23. A driving motor 25 is provided on the back side of the device housing 21. The driving motor 25 will start and drive the rotating disk 23 to rotate. Then, the four extrusion corners 24 of the rotating disk 23 will alternately extrude the conveying hose 26. When a local vacuum appears in the pipelines inside the whole device, the air in the pipelines will continuously discharge, generating a huge suction force.

[0028] A conveying hose 26 is provided inside the installation cavity 22 and outside the rotating disk 23. Connection hoses 27 are connected to both ends of the conveying hose 26. First connection threads 28 are provided inside both connection hoses 27. The conveying hose 26 and the two connection hoses 27 are integrally designed. The driving motor 25 can drive the rotating disk 23 to rotate.

[0029] The connection structure 3 includes an output pipe 31. A first connection flange 32 is provided at the connection of the output pipe 31. A second connection flange 33 is provided on the left side of the first connection flange 32. The first connection flange 32 and the second connection flange 33 are connected by bolts.

[0030] At the connection of the second connection flange 33, there is a two-section pipe 34. On the left side wall of the two-section pipe 34, there is a connection port 35. A second connection thread 36 is connected to the connection port 35. The connection port 35 is connected to the first connection thread 28 of the connection hose 27 through the second connection thread 36. When replacing the conveying hose 26, first, the bolts between the first connection flange 32 and the second connection flange 33 need to be removed to separate the first connection flange 32 and the second connection flange 33. Then, rotate the second connection thread 36 to disconnect the second connection thread 36 from the first connection thread 28 of the connection hose 27. Then, simply replace the entire conveying hose 26 and the connection hose 27.

[0031] The sample injection structure 5 includes a sample injection pipe 51. At the bottom of the sample injection pipe 51, there is a pre-storage tank 52. On one side of the pre-storage tank 52, there is also a feed inlet 53.

[0033] Embodiment 3

[0034] As Figure 4 shown, in order to more intuitively display the internal structure, the conveying hose 26 connected to the connection hose 27 is shown separately.

[0035] The working process of the present utility model: When using a detection device for conveniently loading a sample to be tested, first, the user needs to open the sealing cover on the top of the feed inlet 53, then inject the sample into the pre-storage tank 52 through a syringe, and then close the sealing cover. When sample loading is required, the conveying device 2 will be started. At this time, the drive motor 25 will be started and drive the rotating disk 23 to rotate. Then, the four pressing corners 24 of the rotating disk 23 will alternately press the conveying hose 26. When there is a local vacuum in the pipelines of the entire device, the air in the pipelines will continuously be discharged, generating a huge suction force, which can suck the sample located in the pre-storage tank 52 to the sample injection pipe 51, and enter the sample injection pipe 4 through the conveying device 2 and the two sample delivery pipes 4. Finally, it enters the inside of the detection device body 1 through the sample delivery pipe 4. Through continuous circulation, continuous sample output is achieved. By replacing different conveying hoses 26, viscous liquid samples can also be realized. When replacing the conveying hose 26, first, the bolts between the first connection flange 32 and the second connection flange 33 need to be removed to separate the first connection flange 32 and the second connection flange 33. Then, rotate the second connection thread 36 to disconnect the second connection thread 36 from the first connection thread 28 of the connection hose 27. Then, simply replace the entire conveying hose 26 and the connection hose 27.
