[0055] Referring to Figure 5 , the mounting mechanism 4 comprises a sliding block 41, a magnetic attraction assembly 42, a driving assembly 43, a mounting seat assembly 44 and a rotating clamping member 45.

[0056] In the embodiment, the number of the sliding blocks 41 is two. The sliding blocks 41 are symmetrically mounted on both sides of the pressure bucket 3. The housing 1 is provided with a sliding groove 12, which comprises a horizontal sliding groove 121 and a vertical sliding groove 122. The horizontal sliding groove 121 is provided in the inner wall of the housing 1 and extends in the horizontal direction. The vertical sliding groove 122 is connected to the tail of the horizontal sliding groove 121. The sliding block 41 slides into the mounting cavity 11 through the horizontal sliding groove 121, and when the sliding block 41 is located at the tail of the horizontal sliding groove 121, it can move downward in the vertical sliding groove 122 under the action of gravity and be clamped into the vertical sliding groove 122, so that the pressure bucket 3 is preliminarily positioned.

[0057] Referring to Figure 5 and Figure 6 , the magnetic attraction assembly 42 comprises an upper magnet 421 and a lower magnet 422. The bottom of the pressure bucket 3 is provided with a bucket body mounting groove 31 for mounting the upper magnet 421. The upper magnet 421 is mounted in the bucket body mounting groove 31. The lower magnet 422 is mounted on the driving assembly 43.

[0058] Referring to Figure 6 and Figure 7 , the driving assembly 43 comprises a pressure plate 431, a reset button 432 and pressure springs 433. The inner bottom surface of the housing 1 is provided with a square groove 13. The pressure plate 431 vertically slides in the square groove 13. The pressure springs 433 are arranged in the square groove 13. The number of the pressure springs 433 is four, and they are distributed at four corners in the square groove 13. One end of the pressure spring 433 abuts against the inner bottom surface of the square groove 13, and the other end abuts against the pressure plate 431. The pressure spring 433 has a tendency to drive the pressure plate 431 to move upward. The reset button 432 is integrally arranged on the top of the pressure plate 431. By pressing the reset button 432, the pressure plate 431 can move downward.

[0059] The lower magnet 422 is mounted on the top of the pressure plate 431. The pressure plate 431 is provided with a bottom surface mounting groove 4311 for mounting the lower magnet 422. When the sliding block 41 is located in the vertical sliding groove 122, the upper magnet 421 can be attracted to the lower magnet 422. When the pressure bucket 3 needs to be disassembled, the reset button 432 is pressed, and the reset button 432 drives the pressure plate 431 to move downward against the elastic force of the pressure spring 433. The lower magnet 422 moves downward synchronously with the pressure plate 431, so that the lower magnet 422 is separated from the upper magnet 421.

[0060] Referring to Figure 5 and Figure 8The mounting seat assembly 44 comprises a ring seat 441 and a reset spring 442. The ring seat 441 is arranged on the inner bottom surface of the shell 1 and is fixed on the inner bottom surface of the shell 1 by bolts. The ring seat 441 is provided with an annular cavity 4411 for vertically inserting the pressure barrel 3 and limiting the pressure barrel 3 in the circumferential direction. The reset spring 442 is arranged in the annular cavity 4411, and in order to limit the reset spring 442 from popping out of the annular cavity 4411, the ring seat 441 is provided with a limiting piece 4412 on the inner circumferential wall of the annular cavity 4411, which abuts against the top of the reset spring 442 and limits the reset spring 442 in the annular cavity 4411.

[0061] In combination Figure 5 , Figure 6 and Figure 8 , when the sliding block 41 slides into the vertical sliding groove 122, the pressure barrel 3 is synchronously moved downward and vertically inserted into the annular cavity 4411. During the process of inserting the pressure barrel 3 into the annular cavity 4411, the pressure barrel 3 drives the reset spring 442 to compress, and the upper magnet 421 is attracted to the lower magnet 422. The attraction force between the upper magnet 421 and the lower magnet 422 is greater than the elastic force of the reset spring 442, so that the pressure barrel 3 can be fixed in the annular cavity 4411.

[0062] When the pressure barrel 3 is disassembled, the lower magnet 422 is separated from the upper magnet 421 by pressing the reset button 432, the reset spring 442 releases the pressure to drive the pressure barrel 3 to move upward, the sliding block 41 can exit from the vertical sliding groove 122 and return to the horizontal sliding groove 121, at this time the pressure barrel 3 can be horizontally exited from the mounting cavity 11.

[0063] Referring to Figure 5 and Figure 9 , the rotating clamping member 45 is rotatably arranged in the inner wall of the shell 1. The rotating clamping member 45 comprises a clamping end 451 and a driving end 452, which are respectively located on both sides of the rotation axis. The clamping end 451 is semicircular in cross section and has a semicircular groove 4511 capable of being engaged with the pressure barrel 3. A rubber pad 4512 is arranged in the semicircular groove 4511.

[0064] The driving end 452 has an abutting portion 4521, which abuts against the bottom of the sliding block 41 when the sliding block 41 is located in the vertical sliding groove 122.

[0065] The rotating clamping member 45 has a storage state and a clamping state. When the rotating clamping member 45 is in the storage state, the clamping end 451 abuts against the inner wall of the shell 1, and the rotating clamping member 45 does not fix the pressure barrel 3.

[0066] When the pressure barrel 3 is installed and the sliding block 41 is vertically clamped into the vertical sliding groove 122, the sliding block 41 abuts against the abutting portion 4521 and drives the abutting portion 4521 to rotate downward, at this time, the clamping end 451 can rotate upward in the direction close to the pressure barrel 3, so that the clamping end 451 is clamped on the outer wall of the pressure barrel 3, and the rubber pad 4512 abuts against the outer wall of the pressure barrel 3, at this time, the rotary clamping piece 45 is in the clamping state.

[0067] In order to make the clamping end 451 more firmly fixed to the pressure barrel 3, the clamping end 451 is slidably provided with an extension segment 4514. The clamping end 451 is provided with an extension groove 4513 on the inner wall of the half-ring groove 4511, and the extension groove 4513 is arranged along the circumferential direction of the half-ring groove 4511. The extension segment 4514 is slidably installed in the extension groove 4513.

[0068] When the rotary clamping piece 45 is in the clamping state, the extension segment 4514 can slide out of the clamping end 451 and form a circular through groove 453 with the clamping end 451, so as to further clamp the pressure barrel 3.

[0069] With reference to Figure 5 and Figure 9 , in order to make the rotary clamping piece 45 not easily occupy the space of the installation cavity 11 when the rotary clamping piece 45 is in the storage state, the inner wall of the shell 1 is provided with a storage groove 14, and the rotary clamping piece 45 is embedded in the storage groove 14.

[0070] Embodiment 2:

[0071] Compared with the embodiment 1, the new pure water membrane washing large-flow zero stale water purifier of the embodiment 2 is different from the embodiment 1 only in the structure of the rotary clamping piece 45, and the rest of the structures are the same as those of the embodiment 1, which will not be repeated here.

[0072] With reference to Figure 10 and Figure 11 , in the embodiment, the number of the rotary clamping pieces 45 is two, and the two rotary clamping pieces 45 are symmetrically arranged on the two sides of the pressure barrel 3. The clamping end 451 of each of the two rotary clamping pieces 45 is provided with a connecting magnetic sheet 4515, and when the rotary clamping piece 45 is in the clamping state, the clamping ends 451 on the two sides abut against each other and are fixed by the connecting magnetic sheet 4515. In addition, the two half-ring grooves 4511 are combined to form a circular through groove 453 for the pressure barrel 3 to pass through and be fixed.

[0073] The implementation principle of the new pure water membrane washing large-flow zero stale water purifier of the embodiment of the utility model is as follows:

[0074] When the pressure barrel 3 is installed, the sliding block 41 slides into the horizontal sliding groove 121, and when sliding to the tail of the horizontal sliding groove 121, is clamped vertically downward into the vertical sliding groove 122, and at the same time, the pressure barrel 3 is clamped vertically into the annular cavity 4411 so that the upper magnet 421 and the lower magnet 422 are magnetically attracted and matched; the sliding block 41 is in abutment with the driving end 452 in the vertical sliding groove 122 and drives the clamping end 451 to rotate upward from the storage groove 14 to clamp the pressure barrel 3.

[0075] When the pressure barrel 3 is disassembled, the reset button 432 is pressed, the driving assembly 43 drives the lower magnet 422 to separate from the upper magnet 421. At the same time, the reset spring 442 moves upward to pop the pressure barrel 3 out of the annular cavity 4411, and the sliding block 41 slides upward synchronously, so that the sliding block 41 separates from the driving end 452, causing the clamping end 451 to change from the clamping state to the storage state, and finally the sliding block 41 is slid out of the horizontal sliding groove 121, to complete the disassembly of the pressure barrel 3.
