Testing the components requires manual operation, that is, it is necessary to separately take a container for holding liquid, pour the purified liquid output from the purification water outlet into the input container, place the test pen in the container so that the liquid submerges the end of the test pen, and after the test is completed, pour the liquid back into the water tank. This operation is troublesome, time-consuming, and laborious. Content of the Utility Model

[0020] like Figure 2 , Figure 3 As shown, the detection mechanism 4 includes a test pen 41, a test tube 42 and a flow collecting and draining assembly 43. The input end of the test tube 42 is connected to the output end of the fourth connecting tube 8, and the output end of the test tube 42 is connected to the water tank 3. The test pen 41 is fixedly connected to the water tank 3. The test end of the test pen 41 extends into the test tube 42. The test pen 41 is a TDS test pen. The TDS test pen, also known as a TDS water quality test pen or a water quality test pen, is a simple portable water quality testing tool used to measure the TDS value in water or the conductivity of water to determine The purity or pollution degree of water, the test tube 42 is provided with a mounting hole 421 for the test pen 41 to pass through, and the collecting and draining assembly 43 is arranged in the test tube 42. The collecting and draining assembly 43 is used to allow the purified water to accumulate in the test tube 42 and cover the test end of the test pen 41, and to open after the purified water accumulates to a certain extent to allow the purified water to flow into the water tank 3. Through the design of the collecting and draining assembly 43, it cooperates with the test pen 41 to realize real-time detection of the purified water after filtering by the filter 2, and the detection is convenient and fast, saving manpower.

[0021] like Figure 2 , Figure 3As shown in the figure, the current collecting and discharging assembly 43 includes a fixing plate 431, a movable plate 432 and a mounting seat 433. The fixing plate 431 is fixedly connected to the inner wall of the test tube 42. The fixing plate 431 has a through hole 4311 for accommodating the movable plate 432. The mounting seat 433 is fixedly connected to the inner wall of the test tube 42. The movable plate 432 is located in the through hole 4311 of the fixing plate 431, and the movable plate 432 is elastically connected to the mounting seat 433. The mounting seat 433 is located below the fixing plate 431. This mounting method utilizes the resilience of the elastic element.

[0022] As Figure 2 , Figure 3 shown in the figure, the current collecting and discharging assembly 43 includes an elastic element 434. A connecting rod 4321 is arranged on the bottom surface of the movable plate 432. A sliding cavity 4331 for accommodating the connecting rod 4321 is formed on the mounting seat 433. The other end of the connecting rod 4321 is located in the sliding cavity 4331, and the connecting rod 4321 is slidably connected to the mounting seat 433. The elastic element 434 is located in the sliding cavity 4331. One end of the elastic element 434 abuts against the connecting rod 4321, and the other end abuts against the mounting seat 433.

The concentrated water is output from the concentrated water outlet 21 to the water tank 3 to realize the recycling of the test water.

[0026] Due to the elastic support of the elastic element 434, the purified water can stay in the test tube 42, that is, above the fixing plate 431, so that the purified water submerges the test end of the test pen 41, thus realizing automatic detection. After the test tube 42 is filled, due to the weight of the water, the movable plate 431 moves downward until it disengages from the through hole 4311 of the fixing plate 431, so that the purified water can flow into the water tank 3. This method is for the convenience of detection, saving personnel operation, and on the other hand, it can realize real-time staged detection.
