[0002] Collect water samples from polluted water bodies and analyze them to obtain basic data on water pollution. The water samples used for analysis should be representative and reflect the degree of pollution, chemical composition and characteristics of the water body. The sampling method, location, time and frequency should be determined according to the characteristics of the water body and the purpose of analysis. Generally, it is divided into river water sampling, seawater sampling and lake water sampling.

[0003] A search revealed that in the prior art, application number CN201220162832.X discloses a wastewater sampler. During sampling, the outlet end of the one-way suction balloon is first sealed to the conduit. The sampling head is then inserted into the wastewater to be sampled, and positive pressure is applied to the sampling bottle to expel the gas from the sampling bottle and the infusion tube. Next, the suction end of the one-way suction balloon is sealed to the conduit. By squeezing the one-way suction balloon, the wastewater is sucked into the sampling bottle to achieve the required sampling volume. This wastewater sampling bottle has a simple structure, is easy to carry, is easy to operate, and will not leak or splash onto the human body.

[0004] However, the following drawbacks still exist in this device and existing technology:

[0005] Wastewater samplers are inconvenient to carry and move, and the collected wastewater may spill during the process. In addition, there are many places to sample wastewater from rivers, which requires the sampler to move around constantly, increasing the burden on the sampler. Furthermore, the sample bottles after sampling are inconvenient to carry, which increases the overall sampling difficulty. Utility Model Content
