[0025] Example

[0026] Reference Figure 1-4 This is an embodiment of the present invention, which provides a portable water quality testing device, comprising:

[0027] The liquid storage assembly 100 includes a handle 101, a support plate 102 fixedly connected to the middle side wall of the handle 101, a drainage tube 103 encapsulated at the end of the support plate 102, and a liquid storage tank 104 inserted into the bottom of the handle 101. The drainage tube 103 and the liquid storage tank 104 are respectively connected to the inside of the handle 101.

[0028] The sampling assembly 200 includes a liquid pump 201 sealed inside the handle 101, a liquid collection tube 202 inserted into the end of the drainage tube 103, and a sensor sleeve 203 installed on the side wall of the liquid collection tube 202. The liquid pump 201 inlet is connected to the liquid collection tube 202 through a pipe, and the liquid pump 201 outlet pipe is inserted into the liquid storage tank 104.

[0029] The handle 101 is connected to the support plate 102 at one end and to the storage tank 104 at the other end, enabling effective connection and coordinated operation between the components. This facilitates sampling and testing in conjunction with the drainage tube 103. The storage tank 104 stores the collected water sample. The liquid pump 201 is sealed inside the handle 101, with its inlet connected to the sampling tube 202 via a pipe, and its outlet pipe inserted inside the storage tank 104. The liquid pump 201 serves as the power source for water sample extraction, pressurizing and transporting the water sample collected by the sampling tube 202 to the storage tank 104, ensuring the smooth collection and transfer of the water sample. The sampling tube 202 is inserted into the end of the drainage tube 103, directly contacting the water sample for collection. The sensor sleeve 203 is installed on the side wall of the sampling tube 202, used to install various water quality detection sensors to monitor relevant water quality parameters such as pH and dissolved oxygen in real time during water sample collection.

[0030] Specifically, the sampling assembly 200 also includes a filter element 204 inserted into the inner side of the end of the liquid collection tube 202, with the end of the filter element 204 extending to the side wall of the end of the liquid collection tube 202.

[0031] The filter element 204 extends to the side wall of the liquid collection tube 202, which can filter out impurities and particulate matter in the water sample, providing a relatively clean water sample for subsequent water quality testing.

[0032] Furthermore, the sampling assembly 200 also includes a cover 205 sleeved on the outside of the drainage tube 103. The end of the cover 205 extends to the side wall of the liquid collection tube 202. The inner side wall of the cover 205 is provided with a relief groove structure that cooperates with the drainage tube 103, and the cover 205 is fixedly connected to the side wall of the support plate 102.

[0033] The main function of the cover 205 is to protect the liquid collection tube 202 and the drainage tube 103 from damage caused by external impact during use. At the same time, it can also prevent the interference of surrounding environmental impurities on the water sample collection process to a certain extent. It can also add components such as electric heating tubes or ultraviolet lamps as needed to assist in the treatment of the water body and ensure the accuracy of water sampling and testing.

[0034] Preferably, the liquid storage assembly 100 also includes a rubber sleeve 105 fitted onto the bottom of the handle 101, the rubber sleeve 105 being snapped into the side wall of the liquid storage tank 104.

[0035] The rubber sleeve 105 is fitted onto the bottom of the handle 101 and snapped onto the side wall of the liquid storage tank 104, which serves both as an anti-slip function and as a way to prevent water leakage.

[0036] It should be noted that the liquid storage assembly 100 also includes a sleeve 106 hinged to the side wall of the support plate 102, and a pull rod 107 inserted into the inside of the sleeve 106. The end of the pull rod 107 is hinged to the side wall of the liquid storage tank 104. The liquid storage assembly 100 also includes a tension spring 108 fixedly connected inside the sleeve 106. The end of the tension spring 108 is bolted to the end of the pull rod 107.

[0037] The sleeve 106 works in conjunction with the pull rod 107 and the tension spring 108 to make the liquid storage tank 104 easier to install and remove. The elasticity of the tension spring 108 can firmly fix the liquid storage tank 104 and prevent it from falling off accidentally.

[0038] When using the portable water quality testing device for water sample collection and testing, the user first holds the handle 101 and places the sampling tube 202 into the water sample to be tested. The pump 201 is then activated, generating suction that draws the water sample through the sampling tube 202. During this process, the filter element 204 performs preliminary filtration, removing impurities. The filtered water sample then passes sequentially through the drainage tube 103 and the internal channel of the handle 101, and is finally pressurized and transported by the pump 201 to the storage tank 104 for storage. While water samples are being collected, the water quality sensor installed in the sensor sleeve 203 starts working, detecting various parameters of the water sample in real time and transmitting the data to the corresponding display device. When it is necessary to replace the storage tank 104 or perform maintenance on the device, since the pull rod 107 is connected to the sleeve 106 through the tension spring 108, pulling the pull rod 107 outwards overcomes the elastic force of the tension spring 108, and the storage tank 104 can be pulled out from the bottom of the handle 101. During installation, the storage tank 104 is inserted into the bottom of the handle 101, the pull rod 107 is released, the tension spring 108 returns to its original deformation, and the pull rod 107 drives the storage tank 104 to be firmly fixed.

[0039] In summary, the overall device is designed to be portable, with the handle 101 as its core. All components are tightly connected and rationally arranged, facilitating one-handed operation. Whether in field environments or laboratory settings, it allows for easy water sample collection and real-time testing, significantly improving the efficiency of the testing process. The filter element 204 at the end of the sampling tube 202 effectively filters impurities in the water sample, preventing interference with subsequent testing and ensuring the accuracy of the results. Simultaneously, the cover 205 protects the sampling tube 202 and the drainage tube 103, reducing the possibility of external impurities entering the water sample and further enhancing its purity. By installing different types of water quality sensors within the sensor sleeve 203, multiple water quality parameters can be detected simultaneously, meeting diverse testing needs and providing rich data support for a comprehensive assessment of water quality. The storage tank 104, through the coordinated structure of the pull rod 107, sleeve 106, and tension spring 108, allows for convenient installation and disassembly, facilitating tank replacement for multiple water sample collections. It also facilitates cleaning and maintenance of the storage tank, reducing the device's operating costs and maintenance complexity.
