[0002] Ultrapure water machine is a water treatment equipment that processes raw water such as tap water, removes the conductive medium in the water almost completely, and removes the undissociated colloids, gases and organic matter in the water to a very low level. The general water resistivity is 18.2MΩ·cm (25℃). In scientific research experiments, in order to improve the quality of collected samples and avoid contamination during the measurement process to the greatest extent, ultrapure water is required for pure water blank correction, solution preparation and container cleaning.

[0062] Example 2: Please refer to Figure 8 As shown, compared with Example 1, as another embodiment of the present invention, a pattern groove 32 is provided on a side of the pad 31 away from the adjustment column 30; during operation, the friction force is increased by providing the pattern groove 32 to avoid sliding of the pad 31 when supporting.

[0063] Working principle: First, the staff pulls the pull rod 18, and the universal wheel 17 cooperates to drive the chassis 1 and its connected components to move to the designated work site as a whole. The damper 5 and the shock-absorbing gasket 19 (shock-absorbing sponge) are arranged in the chassis 1 to play a buffering and shock-absorbing role, so as to avoid the inner frame 6 in the chassis 1 and its connected pretreatment unit, reverse osmosis unit, ultraviolet sterilizer 10, nuclear industry-grade resin column 11, conductivity tester 12, 0.22μm precision filter 13 and battery 14 from being bumpy and violent during the transportation and displacement process. The raw water first flows into the crude column 40 from the water inlet pipe 20, and then flows into the pretreatment unit for purification after being processed by the crude column 40, and then flows into the reverse osmosis unit for reprocessing, and then flows into the ultraviolet sterilizer 10 for sterilization. The ultraviolet sterilizer 10 adopts a UV ultraviolet lamp component, and oxidizes organic matter through a dual-wavelength UV lamp to effectively reduce total organic carbon water, and then flows into the nuclear industry grade resin column 11 for reprocessing. The nuclear industry grade resin column 11 is an ultrapure water polishing resin with It has the characteristics of large-capacity purification, stable chemical properties, no decomposition, no oligomers, monomers and additives, etc., ensuring extremely low dissolution rate and top water quality, and then passes through the conductivity tester 12 (i.e. imported + GF + industrial ultrapure water conductivity tester, electrode constant 0.01, with sound and light alarm and touch screen function) for conductivity test, and gradually flows into the 0.22μm precision filter 13 for precision filtration treatment to make the water quality purer. When water is needed, press the water gun 39 and the treated pure water can flow into the water gun 39 through the water outlet pipe 15 for discharge; the battery 14 is used for power supply, and 200L of ultrapure water can be produced on a single charge, which is suitable for field work without power supply. The battery 14 can be on standby for a week. When not in use, the water machine is set to self-circulate for 2 minutes in 3 hours to ensure the cleanliness of the internal pipeline and shorten the preparation time for water production; the device is small in size, regular in shape, and shockproof, which is easy to transport and carry, and has a low price. It is easy to meet the portability and easy operation requirements of field scientific research and field investigation, and can also get rid of the restrictions on fixed water sources and power supplies, and has the advantages of durability and easy cleaning and replacement;

[0064] In the initial state, the limiting hole 83 is locked with the limiting block 85. When the inner frame 6 and the melt-blown filter element 72 and the activated carbon filter 73 connected thereto need to be taken out and replaced, when the connecting frame 71 is separated from the inner frame 6, the operator pulls the limiting rod 84, thereby driving the limiting block 85 to move, and the spring 86 is compressed until the limiting block 85 is separated from the limiting hole 83 and is completely located inside the receiving hole 82. The limiting rod 84 is kept pulled unchanged, and the inner frame 6 and the melt-blown filter element 72 and the activated carbon filter 73 connected thereto can be taken out and replaced. By setting the baffle 87, it is convenient to play a blocking role to prevent external debris (such as dust) from entering the passing hole 81, the receiving hole 82 and the limiting hole 83 through the avoidance groove 1 89, which is convenient for hygienic maintenance. By setting the handle 88, it is convenient to pull the baffle 87, the limiting rod 84 and the limiting block 85. By setting the threaded connection, it is convenient to disassemble and assemble the limiting rod 84 and the limiting block 85.

[0065] In order to facilitate the use of a water source at a long distance, the operator rotates the clamping tube 23 to make it threadedly connected with the water inlet pipe 20, so that the water source at a long distance flows into the water inlet pipe 20 through the drainage pipe 22 and the clamping tube 23. The clamping ring 21 is provided to facilitate the guidance and limitation of the drainage pipe 22 to prevent the drainage pipe 22 from swinging during the water flow process; when the water inlet work is not performed and the water inlet pipe 20 is separated from the clamping tube 23, in order to prevent external debris (such as dust) from entering the water inlet pipe 20, the operator clamps the sealing block 26 with the water inlet pipe 20 for blocking; the connecting rope 25 and the limiting ring 24 are provided to facilitate the prevention of the loss of the sealing block 26 when it is not clamped;

[0066] In order to facilitate the stable support of the chassis 1 and prevent the chassis 1 from sliding during operation, the support leg 29 is rotated to rotate ninety degrees around the limit column 28, and then each adjustment column 30 is rotated in turn until each cushion block 31 is in stable contact with the ground; the interface pipe 33 is a polypropylene pipe, and the outer surfaces of the ultraviolet sterilizer 10 and the circulating booster pump 91 are both provided with rubber shock-proof pads; during operation, imported polypropylene pipes are used to reduce the dissolution rate of the pipeline, and the rubber shock-proof pads are provided to prevent the ultraviolet sterilizer 10 and the circulating booster pump 91 from being easily damaged during carrying.
