The locking nut 18 is located on the outside of the fastening screw 17, and the locking nut 18 is close to the fixing plate 16.

[0039] Among them, the bottom water tank 2, the middle water tank 3 and the top water tank 4 provide installation positions for the fixing plate 16, and the fixing plate 16 provides an installation position for the fastening screw 17.

[0043] Exemplary water leakage prevention module

[0044] Generally speaking, in the prior art, the connector and connection cap between the drain pipe 19 and the external delivery pipe 60 are threaded. Since the water supply is intermittent, the two are often in a process of alternating looseness and tightness. The unstable water pressure can easily lead to leakage between the two, requiring frequent maintenance by staff and increasing their workload. Therefore, in some embodiments of the present invention, the outer end of the drain pipe 19 is connected to the external delivery pipe 60 through a water leakage prevention module 30. The water leakage prevention module 30 prevents leakage at the connection between the drain pipe 19 and the external delivery pipe 60.

[0045] like Figures 5-10As shown, the water leakage prevention module 30 of this structure includes a leak-proof seat assembly 40 and a leak-proof cap assembly 50, wherein the leak-proof seat assembly 40 is installed on the drain pipe 19, and the leak-proof cap assembly 50 is installed on the external transmission pipe 60, and the leak-proof cap assembly 50 is connected to the leak-proof seat assembly 40. When in use, the external transmission pipe 60 is installed and connected to the drain pipe 19. Here, the water leakage prevention module 30 includes the leak-proof seat assembly 40 and the leak-proof cap assembly 50. The mutual connection between the leak-proof seat assembly 40 and the leak-proof cap assembly 50 prevents leakage, thereby reducing the number of on-site inspections by staff and reducing the workload of staff.

[0046] Furthermore, some embodiments of the present invention provide the specific structure of the leak-proof seat assembly 40 and the leak-proof cap assembly 50. Here, the leak-proof seat assembly 40 of the structure includes an outer leak-proof seat portion 41 and an inner leak-proof seat portion 42. Here, the inner leak-proof seat portion 42 is connected to the drain pipe 19, and the outer leak-proof seat portion 41 is movably installed on the inner leak-proof seat portion 42. The leak-proof cap assembly 50 includes an inner leak-proof cap 51 and an inner fixed cap 52. Here, the inner leak-proof cap 51 is connected to the outer delivery pipe 60, and the inner fixed cap 52 is installed on the inner leak-proof cap 51. When in use, the inner leak-proof cap 51 is connected to the outer delivery pipe 60. 1 is installed on the inner leak-proof seat 42, and the outer leak-proof seat 41 is also connected to the inner fixing cap 52. The inner leak-proof cap 51 and the inner leak-proof seat 42 are screwed together, and the outer leak-proof seat 41 and the inner fixing cap 52 are locked to each other. The above connection between the outer leak-proof seat 41 and the inner fixing cap 52 prevents the inner leak-proof cap 51 and the inner leak-proof seat 42 from loosening due to rotation, thereby preventing leakage, reducing the recoil effect, reducing the number of on-site inspections by staff, and reducing the workload of staff.

[0047] Exemplary outer leak-proof seat

[0048] Furthermore, some embodiments of the present invention provide a specific structure of the above-mentioned outer leak-proof seat portion 41, where the outer leak-proof seat portion 41 of the structure includes a first outer leak-proof seat 411 and a second outer leak-proof seat 412, the second outer leak-proof seat 412 is installed on the first outer leak-proof seat 411, and the two constitute a cylindrical seat with a T-shaped cross-section, and the above-mentioned inner leak-proof seat portion 42 includes a first inner leak-proof seat 421 and a second inner leak-proof seat 422, the second inner leak-proof seat 422 is installed on the first inner leak-proof seat 421, the second inner leak-proof seat 422 is screwed to the inner leak-proof cap 51, the first outer leak-proof seat 411 is movably installed on the first inner leak-proof seat 421, and the second inner leak-proof seat 422 is screwed to the inner leak-proof cap 51. An outer leak-proof seat 411 can be moved on the first inner leak-proof seat 421, so that the second outer leak-proof seat 412 is sleeved on the outside of the second inner leak-proof seat 422 and can be connected to the inner fixing cap 52. Furthermore, a tightening mechanism 43 is installed in the second inner leak-proof seat 422, and the tightening mechanism 43 is used to push against the inner end of the first outer leak-proof seat 411, so that there is support between the second outer leak-proof seat 412 and the inner fixing cap 52, so that the two can be locked and connected together to prevent the screw connection between the second inner leak-proof seat 422 and the inner leak-proof cap 51 from loosening and causing leakage, thereby reducing the number of times staff enter the site for maintenance and reducing the work intensity of staff.

[0049] Exemplary tightening mechanism

[0050] Furthermore, in some embodiments of the present invention, the above-mentioned tightening mechanism 43 includes a tightening baffle seat 431 and a plurality of tightening telescopic rods 432, wherein the inner end of the second inner leak-proof seat 422 has a telescopic hole 423 corresponding to the tightening telescopic rod 432, and the tightening telescopic rod 432 is installed in the telescopic hole 423, the tightening baffle seat 431 is sleeved on the first inner leak-proof seat 421 and connected to the plurality of tightening telescopic rods 432, and the tightening telescopic rods 432 provide elastic support for the tightening baffle seat 431, when the first outer leak-proof seat 411 in the outer leak-proof seat portion 41 is in the first inner leak-proof seat 421. 21, the second outer leak-proof seat 412 is connected to the inner fixing cap 52. At this time, the first outer leak-proof seat 411 is pressed against the tightening baffle seat 431, and the tightening telescopic rod 432 is compressed, and the internal telescopic spring 4321 provides elastic support, so that the second outer leak-proof seat 412 is supported outward and is more firmly connected to the inner fixing cap 52. In this way, the inner leak-proof cap 51 inside the inner fixing cap 52 is synchronized with the second inner leak-proof seat 422, avoiding the loose rotation of the screw connection between the two and causing leakage, thereby reducing the number of maintenance times for staff and reducing the work intensity of staff.

[0051] Exemplary first L-shaped locking slide

[0052] Furthermore, in some embodiments of the present invention, two first L-shaped locking slides 44 are provided on the outer wall of the first inner leak-proof seat 421. Specifically, the first L-shaped locking slide 44 includes a first long slide section 441, a first curved slide section 442 and a first locking slide section 443, wherein the first long slide section 441 is arranged along the length direction of the first inner leak-proof seat 421, one end of the first curved slide section 442 is connected to the end of the first long slide section 441 and close to the second inner leak-proof seat 422, and the first locking slide section 443 is provided on the first curved slide section 44 2 is facing away from the second inner leak-proof seat 422, thereby forming the above-mentioned first L-shaped locking slide 44. Correspondingly, a first locking protrusion 413 corresponding to the first L-shaped locking slide 44 is installed on the inner wall of the first outer leak-proof seat 411. Therefore, the first locking protrusion 413 moves along the first L-shaped locking slide 44, so that the first outer leak-proof seat 411 moves first and then rotates on the first inner leak-proof seat 421, thereby realizing the synchronous fixation of the first outer leak-proof seat 411 on the first inner leak-proof seat 421, and then the second outer leak-proof seat 412 is also synchronously locked and connected with the inner fixed cap 52.

[0053] Exemplary Second L-Shaped Locking Slide

[0054] Furthermore, in some embodiments of the present invention, two second L-shaped locking slides 53 are provided on the above-mentioned inner cap 52, specifically, the second L-shaped locking slide 53 includes a second long slide section 531, a second arc-shaped slide section 532 and a second locking slide section 533, wherein the second long slide section 531 is arranged along the length direction of the inner cap 52, one end of the second arc-shaped slide section 532 is connected to the end of the second long slide section 531 and is close to the inner leak-proof cap 51, and the second locking slide section 533 is provided on the other end of the second arc-shaped slide section 532 toward the inner leak-proof cap 51, and correspondingly, a second locking protrusion 413 corresponding to the second L-shaped locking slide 53 is provided on the inner wall of the second outer leak-proof seat 412. Therefore, when the second locking protrusion 413 in the second outer leak-proof seat 412 moves along the second L-shaped locking slide 53, the second outer leak-proof seat 412 is also rotated after the inner fixed cap 52 moves, thereby realizing the locking connection between the second outer leak-proof seat 412 and the inner fixed cap 52. In this way, the outer leak-proof seat 41 realizes the synchronous connection between the first inner leak-proof seat 421 and the inner fixed cap 52 through the first outer leak-proof seat 411 and the second outer leak-proof seat 412, respectively, so that the inner leak-proof cap 51 and the second inner leak-proof seat 422 remain synchronized, avoiding the loose rotation of the screw connection between the two and causing leakage, thereby reducing the number of maintenance times for staff and reducing the work intensity of staff.

[0055] Furthermore, an inner extension cap 511 is provided at the outer end of the inner leak-proof cap 51, and an inner leak-proof groove 424 is opened at the outer end of the second inner leak-proof seat 422. An auxiliary inner leak-proof sleeve 512 corresponding to the inner leak-proof groove 424 is installed on the inner leak-proof cap 51, and the inner leak-proof groove 424 is also installed with a first inner pre-tightening baffle 426. Therefore, after the inner leak-proof cap 51 is screwed into the second inner leak-proof seat 422, the inner extension cap 511 enters the interior of the second inner leak-proof seat 422 to further improve the leak-proof effect. At the same time, the auxiliary inner leak-proof sleeve 512 also enters the inner leak-proof groove 424 to press against the first inner pre-tightening baffle 426, which also further improves the leak-proof effect.

[0056] Furthermore, an outer blocking ring 427 corresponding to the first outer leak-proof seat 411 is installed on the first inner leak-proof seat 421, and the outer blocking ring 427 prevents the first outer leak-proof seat 411 from sliding down from the first inner leak-proof seat 421; a second inner pre-tightening blocking piece 413 is installed at the outer end of the first outer leak-proof seat 411, and the second inner pre-tightening blocking piece 413 cooperates with the tightening blocking disc seat 431 to prevent the tightening blocking disc seat 431 from entering the first outer leak-proof seat 411, and an outer blocking piece 414 is installed on the outer end of the second outer leak-proof seat 412, so after the inner leak-proof cap 51 enters the second inner leak-proof seat 422, the inner wall of the outer blocking piece 414 contacts the outer wall of the inner leak-proof cap 51, thereby having a shielding effect.
