[0002] Existing water quality analyzers are professional instruments used to analyze the content of water components. They measure items such as BOD, COD, ammonia nitrogen, total phosphorus, total nitrogen, turbidity, pH, and dissolved oxygen in water. In order to protect the water environment, water quality analyzers play an important role in environmental protection, water quality detection, and water resource protection. In addition, water quality analyzers have a small structure and are easy for users to carry and use.

[0003] Existing water quality analyzers require the sensor head to be directly embedded into the water to be tested via a connecting cable. The sensor head is relatively light and is prone to buoyancy when placed in the water. Therefore, it is not convenient to place a counterweight when the sensor head is embedded in the water, making it difficult to reach the expected detection position, reducing detection efficiency, and affecting the convenience of counterweight placement during use. To address this issue, this utility model proposes a portable water quality analyzer. Summary of the Invention

In use, the main body 100 is powered on, the main unit 101 is powered on, and the detection head 103 is inserted into the water to be tested. The main body 100 is small and convenient to carry and use. The main body 100 also includes:

[0023] The counterweight mechanism includes a counterweight component disposed on the outer surface of the bottom end of the detection head 103. A rotating fixing component is disposed at the connection between the upper surface of the counterweight component and the top end of the detection head 103. When the water quality analyzer body 100 is in use and the detection head 103 is embedded in the water, the counterweight mechanism accurately lowers the detection head 103 to the detection position, which is convenient for placing the detection head 103 for detection and use.

[0024] To facilitate the installation of counterweights on the detection head 103 using a counterweight assembly, and to ensure that the counterweights fall to the intended detection position during testing for effective detection, in this embodiment, preferably, the counterweight assembly is located on a counterweight ring 1031 at the bottom of the detection head 103, and the outer surface of the detection head 103 matches the inner surface structure of the counterweight ring 1031. This allows the counterweight ring 1031 to lower the bottom of the detection head 103 to the intended detection position when the detection head 103 needs to be submerged in water for accurate testing.

[0025] To facilitate the fixed installation of the counterweight ring 1031 via a rotating fixing assembly, in this embodiment, preferably, the rotating fixing assembly includes three connecting rods 1032 integrally disposed on the upper surface of the counterweight ring 1031. The top end of each connecting rod 1032 is integrally provided with an internal threaded ring 1033, and the top edge of the detection head 103 is formed with an external threaded structure 1034. In use, the counterweight ring 1031 can be fixedly installed via the connecting rods 1032 after the internal threaded ring 1033 and the external threaded structure 1034 are rotated together, thus facilitating the fixed installation of the counterweight.

[0026] The handheld and placement mechanism includes a handheld component located on one side of the detection host 101. The handheld component has a pressing placement component inside, which allows the water quality detector body 100 to be easily picked up and the detection host 101 to perform detection when in use, and to be easily pressed and fixed after use.

[0027] In order to facilitate handheld testing of the testing host 101 by means of a convenient handheld component, in this embodiment, preferably, the convenient handheld component includes a convenient handheld piece 1011 fixedly installed on one side of the testing host 101 by screws. The rear surface of the convenient handheld piece 1011 is provided with four finger grooves 1014, so that when in use, the operator can hold the convenient handheld piece 1011 and grip it tightly with his fingers in contact with the inner surface of the finger grooves 1014, which facilitates handheld testing operation.

An elastic ring 1013 is glued and fixed to the top edge of the inner part of the placement hole 1012. After the water quality tester body 100 is used, the detection head 103 can be placed inside the placement hole 1012 and tightly fixed by the elastic ring 1013, which facilitates the tight-fitting and protective placement of the detection head 103 after use.

[0029] The working principle and usage process of this utility model are as follows: When using this portable water quality analyzer, the end of the detection head 103 is first inserted into the interior of the internal threaded ring 1033. After the internal threaded ring 1033 is rotated and fixed by the external threaded structure 1034, the counterweight ring 1031 is closed on the end surface of the detection head 103 for counterweight protection. When the main body 100 of the water quality analyzer is in use, the power of the main unit 101 is turned on, and the detection head 103 is embedded in the water to be tested. The counterweight ring 1031 counterweights and lowers the detection head 103 to the position to be tested for testing, which facilitates the achievement of the expected testing position and testing effect and improves the convenience of counterweight placement and testing when using the main body 100 of the water quality analyzer.

[0030] Then, when the water quality analyzer body 100 is in use, the user directly holds the convenient handheld part 1011, inserts their fingers into the inside of the finger groove 1014 to firmly grasp and pick up the water quality analyzer body 100, making it easy to hold and pick up the water quality analyzer body 100 for testing. After testing, after the moisture on the surface of the detection head 103 is dried, the detection head 103 is inserted into the placement hole 1012 and tightly pressed and reinforced by the elastic ring 1013, which makes it easy to protect the detection head 103 after use. It is not easy to be damaged by external objects when carrying and using, thus improving the convenience of hand operation of the water quality analyzer body 100 during use and the protection effect of the detection head 103 after use.
