[0042] Example 2:

[0043] See also Figure 1 、 Figure 2 、 Figure 5 、 Figure 6, and on the basis of Example 1, it is further obtained that: the water inlet part 41 includes a treatment box 411, the treatment box 411 is located on the top surface of the base 1, the treatment box 411 is fixedly connected to the base 1, the right side of the treatment box 411 is connected with a connecting pipe 412, the connecting pipe 412 is connected with the disinfection kettle 2, a water pipe 413 is provided on the left side of the connecting pipe 412, the water pipe 413 is connected with the treatment box 411, the left end face of the water pipe 413 is connected with the right end face of the filter box 311, a sealing plate 414 is provided on the front side of the water pipe 413, and the outer side of the sealing plate 414 is provided with a slide rail, the slide rail is fixedly connected to the front side of the treatment box 411, and the slide rail is slidably connected to the sealing plate 414.

However, during long-term operation, the reverse osmosis membrane 423 may be clogged due to the accumulation of impurities, resulting in a decrease in its reverse osmosis efficiency, thereby pulling the sealing plate 414 to slide along the slide rail, thereby opening the front of the treatment box 411. Next, the operator rotates the bolt 422 to release the clamping state of the bolt 422 and the reverse osmosis membrane 423, so that the reverse osmosis membrane 423 can be easily removed from the treatment box 411 for replacement or cleaning.

[0046] Furthermore, this embodiment uses the reverse osmosis mechanism 4 and the water pipe 413 in the water inlet part 41 to allow the filtered water to enter the treatment box 411 through the water pipe 413, and then undergo reverse osmosis treatment through the reverse osmosis membrane 423.

[0047] When in use, the pre-treatment mechanism 3 uses the water inlet 312 in the filter part 31. First, water enters through the water inlet 312 in the filter part 31. The water after entering first passes through the primary filter 325. The primary filter 325 is used to remove large particles of impurities in the water, such as mud, stones, etc. Subsequently, the water further flows through the adsorption plate 326. The adsorption plate 326 can adsorb tiny particles and suspended matter in the water to further purify the water quality. During long-term operation, the primary filter 325 may be blocked due to the accumulation of impurities. When the primary filter is detected, When the net 325 is clogged, the driving motor 1 314 is started, driving the synchronous wheel 315 to rotate, so that the synchronous wheel 315 and the synchronous belt 316 are driven, so that the synchronous wheel 315 drives the reciprocating threaded rod 321, and the rotation of the reciprocating threaded rod 321 causes the thread block 322 and the entire cleaning part 32 to move along the direction of the reciprocating threaded rod 321. While moving, the motor 2 323 is started, driving the cleaning brush 324 to rotate. The cleaning brush 324 is closely attached to the surface of the primary filter 325, and the accumulated dirt on the primary filter 325 is removed by rotating and brushing. The accumulated impurities are removed and the cleaned impurities fall onto the adsorption plate 326 below. When the adsorption plate 326 needs to be cleaned, the adsorption plate 326 is pulled to slide along the chute 327 and extracted, thereby cleaning the collected substances. Then, the filtered water is introduced into the treatment box 411 through the reverse osmosis mechanism 4 and the water pipe 413 in the water inlet part 41 is used. In the treatment box, the water is further reverse osmosis treated by the reverse osmosis membrane 423, which can remove impurities such as dissolved solids, organic matter, bacteria, etc. in the water, thereby To obtain purer water, however, during long-term operation, the reverse osmosis membrane 423 may be blocked due to the accumulation of impurities, resulting in a decrease in its reverse osmosis efficiency, thereby pulling the sealing plate 414 to slide along the slide rail, thereby opening the front of the treatment box 411. Next, the operator rotates the bolt 422 to release the clamping state of the bolt 422 and the reverse osmosis membrane 423, so that the reverse osmosis membrane 423 can be easily removed from the treatment box 411 for replacement or cleaning, and finally the clean water enters the disinfection kettle 2 through the connecting pipe 412.
