[0031] The specific structure of the multi-channel chemical automatic sampler in this embodiment is described below.

[0032] like Figure 1 As shown, the multi-channel chemical automatic sampler in this embodiment includes a control device 10, a sampling device 20, a sampling tube 30, a sample suction tube 40 and a stirring device 50. Optionally, the control device 10 is used to switch the circuit of the entire device on and off, and the control device 10 can be used to operate the relevant parameters such as the sampling pipeline, sampling volume, start and end of sampling in the subsequent operation process. Furthermore, the sampling device 20 is arranged below the control device 10, and the control device 10 is fixed in the sampling device 20, and the two are communicatively connected to ensure the stable placement of the control device 10 and the setting of relevant parameters of the sampling device 20. Furthermore, the sampling device 20 is provided with a plurality of sampling pipelines, and the sampling tube 30 is connected to the upper end of the sampling device 20, and the sample suction tube 40 is connected to the lower end of the sampling device 20, so that the sample suction tube 40 can be inserted into the chemical, and the sampling tube 30 can be inserted into the sampling bottle, and then the chemical is automatically pumped into the sampling bottle through the sampling device 20, thereby replacing the manual sampling operation in the prior art. Optionally, the stirring device 50 is detachably connected to the sampling device 20, so that the chemical can be stirred. For example, the control device 10 can also be used to set the opening and closing of the stirring device 50 to ensure the automated operation effect of the entire equipment.

[0033] Specifically, in this embodiment, the control device 10 is provided with a control switch 101 and a control panel 102. Optionally, the control switch 101 is provided on one side of the control device 10, and the control panel 102 is provided on the front of the control device 10, and the control switch 101 is used as the main switch of the multi-channel chemical automatic sampler to realize the on and off of the entire circuit. Furthermore, the control panel 102 can be used to set the sampling pipeline, sampling volume, opening and closing of the stirring device 50, and the start and end of sampling, so as to facilitate the operator's touch screen operation and realize the automation of each sampling step. Exemplarily, the control device 10 is internally provided with a rechargeable battery and circuit settings related to the control panel 102, and a charging interface is provided on the outside of the control device 10 to improve the convenience of the operation of the entire device.

[0034] like Figure 1 and Figure 2 As shown, the sampling device 20 in this embodiment includes a pumping assembly 21, a holder 22, an upper top shell 23, a lower bottom shell 24 and a suction cup bracket 25, and is provided with a first conduit 201 and a second conduit 202. The pumping assembly 21 includes a pump body 211, a pump housing 212 and an extrusion assembly 215. A third conduit 213, a hose 214 and a fourth conduit 216 are also provided in the pump body 211. A sliding switch 203 is also provided on the pump body 211, and a rotating wheel 2151 is provided in the extrusion assembly 215.

[0035] Specifically, in the present embodiment, the pumping assembly 21 is rotatably arranged between the upper top shell 23 and the lower bottom shell 24, and the holder 22 is connected to the pumping assembly 21. Thus, the rotation setting of the holder 22 can be realized by the pumping assembly 21, so that the holder 22 can be quickly rotated to the position where the sampling bottle is located, and the sampling bottle is clamped and fixed. Specifically, the opening size of the holder 22 is adjustable, so that the scope of application of the holder 22 is expanded, and sampling bottles of various sizes can be clamped. Further, the pumping assembly 21 rotates the holder 22 to the target position, and after stably clamping the sampling bottle, it can be rotated again so that the sampling lines in the upper top shell 23, the pumping assembly 21 interior, and the lower bottom shell 24 are placed according to their corresponding positions. Exemplarily, the rotation position of the pumping assembly 21 can be set to different gears, so as to facilitate corresponding different sampling lines and ensure a one-to-one correspondence between the corresponding sampling tube 30 and the sampling bottle.

[0036] Optionally, the sampling device 20 is provided with a plurality of sampling pipelines, and each sampling pipeline includes a sampling channel and a sample suction channel that are interconnected. In this embodiment, the sample suction channel is used to absorb chemicals, and the sampling channel is used to transport the absorbed chemicals to a sampling bottle. In this embodiment, a plurality of first conduits 201 are installed above the upper top shell 23, and the sampling tube 30 is connected to the first conduit 201 and can be inserted into the sampling bottle. Similarly, a plurality of second conduits 202 are installed below the lower bottom shell 24 for connecting the sample suction tube 40, and the sample suction tube 40 can be inserted into the chemicals to ensure smooth transportation of the chemicals. For example, the first conduit 201, the sampling tube 30, the second conduit 202 and the sample suction tube 40 are arranged in a one-to-one correspondence. When used in a specific manner, they can be marked accordingly to distinguish them, and then be applied to the pumping operation of different chemicals to avoid cross infection between different chemicals. Illustratively, the sampling tube 30 and the first conduit 201, as well as the sample suction tube 40 and the second conduit 202, are detachably connected. Furthermore, the first conduit 201 and the upper housing 23, as well as the second conduit 202 and the lower housing 24, are also detachably connected. This ensures regular cleaning of each conduit and prevents microbial contamination. Illustratively, the sample suction tube 40 is adjustable in length and must be inserted into the chemical after the stirring device 50 has been deactivated.

[0037] like Figure 2As shown, in this embodiment, the pump housing 212 is slidably mounted on the pump body 211, and a plurality of extrusion assemblies 215 are disposed within the inner cavity of the pump body 211. Chemicals are thereby transported through the sample suction channel and squeezed at the extrusion assembly 215 to the sampling channel, ultimately being transported to the sampling bottle. Furthermore, a sliding switch 203 is disposed on the outside of the pump body 211, and the sliding switch 203 is used to control the sliding of the pump housing 212 on the pump body 211, thereby facilitating subsequent disassembly, cleaning, and drying of the extrusion assembly 215, reducing quality risks, and preventing sample contamination. Specifically, a third conduit 213, a hose 214, and a fourth conduit 216 are disposed within the pump body 211, and the third conduit 213 is connected to the first conduit 201 and serves as a sampling channel. The fourth conduit 216 is connected to the second conduit 202 and serves as a sample suction channel. The third conduit 213 and the fourth conduit 216 are connected via the hose 214, thereby forming a sampling line. Furthermore, the third conduit 213 is provided in a one-to-one correspondence with the first conduit 201, the fourth conduit 216 is provided in a one-to-one correspondence with the second conduit 202, and the hose 214 is provided in correspondence with the sampling pipeline, thereby achieving the effect of multiple sampling pipelines existing at the same time and automatically sampling chemicals in a multi-channel manner. For example, the hose 214 is wound around the outside of several rotating wheels 2151 provided in the extrusion component 215, and can be squeezed by the rotating wheels 2151 to achieve the effect of automatically sucking chemicals. In this embodiment, the extrusion component 215 is configured as a peristaltic pump and is provided with a motor, so that the motor drives multiple peristaltic pumps to ensure the multi-channel pumping effect of chemicals in the sampling pipeline. Optionally, the conduits involved in the sampling pipeline in this embodiment are all made of corrosion-resistant materials to ensure the suction and outflow of samples.

[0038] like Figure 1 As shown, in this embodiment, a suction cup bracket 25 is further provided below the lower base shell 24. The suction cup bracket 25 is rotatably connected to the lower base shell 24 and can be accommodated. When the suction cup bracket 25 is supported on the ground or other work surface, the position of the multi-channel chemical automatic sampler can be fixed to ensure the stability of the entire equipment during the sampling process.

[0039] Furthermore, the stirring device 50 is also provided on the lower bottom shell 24 and can rotate as a whole relative to the sampling device 20 to fully stir the chemicals. Specifically, the stirring device 50 includes a housing, an extension rod, and stirring blades 501. In this embodiment, one end of the extension rod is fixed to the sampling device 20, and the housing is sleeved on the outside of this end of the extension rod. The housing can also be fixed to the lower bottom shell 24. Furthermore, the other end of the extension rod is configured to be retractable so that it can be accommodated in the housing when not in use. Optionally, the telescopic end of the extension rod can be inserted into the chemical, and a plurality of stirring blades 501 are fixed to the outside of the extension rod. The plurality of stirring blades 501 are evenly distributed around the axis of the extension rod, so that when the extension rod rotates, the stirring blades 501 can stir the chemicals. Furthermore, when the stirring device 50 is not in use, the stirring blades 501 can be accommodated in the housing, thereby improving space utilization and facilitating storage of the entire device. Furthermore, the stirring device 50 is detachably connected to the sampling device 20 so that it can be cleaned regularly. At the same time, different stirring devices 50 can be replaced according to the type of chemicals to avoid cross-contamination of chemicals during the sampling process. For example, the stirring blade 501 and the extension rod are also provided with a detachable connection to facilitate the removal of the stirring blade 501 for cleaning and maintenance. For example, the stirring device 50 is made of stainless steel to avoid rust, and the stirring blade 501 is spaced apart from the sample suction tube 40 to ensure that there is no interference between the two during the stirring process.

[0040] Working process: The multi-channel chemical automatic sampler is fixed in a preset position by the suction cup bracket 25; then the pumping assembly 21 is used to move the holder 22 to the sampling bottle, and the sampling bottle is clamped and fixed by the holder 22; then the entire device is opened by the control device 10, and the sampling pipeline, sampling volume, the opening and closing of the stirring device 50, and the parameters related to the start and end of sampling are set using the control panel 102; finally, the sampling is completed, the sampling bottle is removed, and the corresponding catheter is removed for cleaning and drying. The suction cup bracket 25 in this embodiment can ensure the stable placement of the entire device, and the control panel 102 is used to achieve intelligent and automated operation. The peristaltic pump principle of the extrusion assembly 215 in the pumping assembly 21 can achieve the sampling of multiple samples without cross contamination in one device, thereby improving sampling efficiency and ensuring quality requirements during the sampling process. This avoids the manual sampling and manual stirring operations in the prior art, and correspondingly improves work efficiency, reduces the time and frequency of workers' contact with chemicals, and reduces safety hazards.

[0041] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here.
