The second drive wheel 16 is driven by a second hand wheel 23. The valve further comprises: filter tube 2 and second locating plate 17, the other end of valve body 1 passes through screw and filter tube 2 fixed connection. The filter pipe 2 is fixedly connected with the second positioning plate 17, and the second positioning plate 17 positions the second hand wheel 16, so that the possibility of shaking of the second hand wheel 16 in the driving process is reduced. The second driving frame 14 is provided with a second gear part 18 engaged with the second driving wheel 16, and both the second gear part 18 and the second driving wheel 16 are helical gears.
Because the second driving wheel 16 is matched with the second gear part 18, and two ends of the second driving frame 14 are respectively in clearance fit with the valve body 1 and the filter pipe 2, the second driving wheel 16 drives the second driving frame 14 to rotate along the axis of the filter pipe 2.
As shown in fig. 2 and 3, the second driving rack 14 is provided with a second screw portion 19 which is screw-engaged with the second cleaning disc 15, and the second cleaning disc 15 is provided with a plurality of second guide portions 20. Meanwhile, the valve body 1 is provided with a second rectangular groove 21 matched with the second guide part 20, so when the second driving wheel 16 drives the second driving frame 14 to rotate along the axis of the filter pipe 2, the second driving frame 14 makes a linear motion along the second rectangular groove 21 under the action of the second thread part 19.
The second washs dish 15 and is equipped with a plurality of second bellyings with 1 interface of valve body, and the laminating of second bellyings and 1 inside wall of valve body washs the incrustation scale that depends on 1 inboard of valve body in the motion process.
As shown in fig. 3, the cleaned water is filtered by a filtering assembly, which includes: an upper filter body 24, a lower filter body 25, a filter layer 26, and a plurality of first springs 27; the lower filtering body 25 is provided with a plurality of guide posts 28 which penetrate through the filtering pipe 2 and are fixedly connected with the upper filtering body 24, and the contact surfaces of the guide posts 28 and the filtering pipe 2 are sealed by sealing rings 36. The upper filtering body 24 and the lower filtering body 25 are both provided with T-shaped grooves, and two ends of the filtering layer 26 are connected with the T-shaped grooves in a sliding manner. The first spring 27 is disposed between the upper filtering body 24 and the filtering pipe 2, and the first spring 27 is sleeved on the guide post 28.
As shown in fig. 3 and 4, the filter assembly needs to be locked by two locking assemblies, wherein the locking assemblies comprise: a locking case 29, a locking block 30, a second spring 31, and a first cover plate 32. Two locking shells 29 are arranged at two sides of the upper filtering body 24, and the locking shells 29 are fixedly connected with the outer side wall of the filtering pipe 2. The second cover plate 39 is fixedly connected with the locking shell 29, and the locking block 30 is slidably arranged between the locking shell 29 and the second cover plate 39. The lock block 30 is reset by the second spring 31, and the lock block 30 and the lock housing 29 are each provided with a first support portion for supporting the second spring 31.
As shown in fig. 4 and 6, the locking block 30 is provided with a first inclined surface 33, the first inclined surface 33 includes a point a and a point B, the upper filter body 24 is provided with a locking portion 34 engaged with the locking block 30, and the locking portions 34 are provided with second inclined surfaces 35 engaged with the first inclined surfaces 33. The second slope 35 includes points C and D. When the upper filter body 24 descends, the first inclined surface 33 contacts the second inclined surface 35, and the point B of the first inclined surface 33 moves in the direction from the point D to the point C of the second inclined surface 35. At the same time, the locking block 30 slides along the locking shell 29 and compresses the second spring 31, the upper filtering body 24 continues to descend, and when the point B is separated from the point C, the locking block 30 is ejected under the action of the second spring 31. The locking block 30 cooperates with the locking portion 34 to effect locking.
When the filter assembly needs to be replaced, the unlocking assembly is matched with the locking assembly, as shown in figures 3 and 4. The unlocking assembly comprises: a mating block 37, a third spring 38, and a second cover plate 39. The upper filter body 24 is provided with a slide groove portion 40, and the engagement block 37 is slidably provided in the slide groove portion 40. The third spring 38 is used for returning the matching block 37, and the matching block 37 and the sliding groove part 40 are both provided with second supporting parts for supporting the third spring 38. The second cover plate 39 is fixedly connected with the slide groove portion 40, the matching block 37 is slidably arranged between the second cover plate 39 and the slide groove portion 40, and the matching block 37 is provided with a third inclined surface 41 matched with the second inclined surface 35.
As shown in fig. 4 and 6, the third inclined surface 41 includes points E and F, and when the engaging block 37 descends, the point E moves in the direction from the point a to the point B of the first inclined surface 33. As shown in fig. 3, while the locking piece 30 slides along the locking housing 29, moves into the locking housing 29 and compresses the second spring 31.
As shown in fig. 4, the mating block 37 continues downstream. As shown in fig. 6, the engaging block 37 brings the point B on the lock block 30 out of the point C of the lock portion 34. As shown in fig. 3, the filter assembly is released from the locked state by the first spring 27. The engagement piece 37 and the lock piece 30 are returned to the initial positions by the second spring 31 and the third spring 38.
As shown in fig. 2, during operation, the first hand wheel 13 and the second hand wheel 23 rotate the first driving wheel 5 and the second driving wheel 16, and also rotate the first driving frame 3 and the second driving frame 14. The first driving frame 3 and the second driving frame 14 are in threaded fit with the first cleaning disc 4 and the second cleaning disc 15, and the first cleaning disc 4 and the second cleaning disc 15 do opposite linear motion along the rectangular groove. When the first driving wheel 5 and the second driving wheel 16 can not rotate along one direction, the first cleaning disc 4 and the second cleaning disc 15 are driven by the reverse rotation to do back-to-back linear motion along the rectangular groove, and the water scale is cleaned on the inner side wall of the valve body 1 in a reciprocating mode.
As shown in fig. 4, when the scale is cleaned for a certain number of times, the press-fit block 37 brings the second inclined surface 35 into contact with the third inclined surface 41, and at the same time, the locking block 30 is moved into the locking housing 29, and the filter assembly is lifted as a whole under the action of the first spring 27. As shown in fig. 3, while the locking piece 30 is returned to the original position by the second spring 31.
As shown in fig. 3, in order to avoid the outflow of liquid from the filter pipes 2, the lower filter body 25 and the upper filter body 24 are each provided with a boss portion provided with a T-shaped groove. When the first spring 27 lifts the filter assembly body, the boss portion of the lower filter body 25 seals the filter tube 2, and finally the filter layer 26 is drawn out of the T-shaped groove and replaced with a new filter layer 26.
As shown in fig. 4, after the replacement is completed, the upper filter body 24 is pressed to compress the first spring 27 and drive the entire filter assembly to move downward, and the first inclined surface 33 of the locking portion 34 of the upper filter body 24 contacts with the second inclined surface 35 of the locking block 30 to drive the locking block 30 to move into the locking housing 29. When the upper filtering body 24 continues to move downwards, and the first inclined surface 33 is separated from the second inclined surface 35, the locking block 30 is ejected out under the action of the second spring 31 to lock the filtering assembly, and the filtering layer 26 is replaced completely.
Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
