DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-8 A filtering device for a variable frequency water supply pipeline comprises: a filter box 1, a base plate 3 is arranged on the side of the filter box 1, a plurality of filter plates 6 are arranged on the side adjacent to the base plate 3 and the filter box 1, and an auxiliary component 4 is also arranged on the base plate 3; a connecting pipe 2 is arranged on the filter box 1, and the connecting pipe 2 is connected to a water source or a variable frequency water supply pipeline.

[0027] The auxiliary component 4 includes a trapezoidal protrusion 42, an insert block 43, a rotating shaft 44, a first connecting rod 45 and an auxiliary spring 46. The trapezoidal protrusion 42 is fixedly mounted on the side of the base plate 3 and contacts the filter plate 6. The insert block 43 is slidably arranged on the trapezoidal protrusion 42 and plugged into the filter plate 6. The rotating shaft 44 is rotatably arranged on the trapezoidal protrusion 42. The two ends of the first connecting rod 45 are respectively movably connected to the rotating shaft 44 and the insert block 43. The two ends of the auxiliary spring 46 are respectively fixedly connected to the insert block 43 and the trapezoidal protrusion 42. The auxiliary component 4 also includes a movable block 41, a rack 47, a gear 48 and a connecting block 49. The movable block 41 is fixedly mounted on the connecting block On the end surface of 49, a rack 47 is slidably arranged inside the base plate 3, a gear 48 is rotatably arranged inside the base plate 3 and fixedly connected to the rotating shaft 44, and the end of the connecting block 49 away from the movable block 41 is fixedly connected to the rack 47. The number of gears 48 is consistent with the number of filter plates 6, and several gears 48 are meshed with the rack 47, so that the positions of multiple plug-in blocks 43 at the base plate 3 can be adjusted at the same time, so as to achieve the effect of simplifying the operation steps. The inclined surface of the trapezoidal protrusion 42 is upward, and the inclined surface contacts the filter plate 6, so that after the position of the plug-in block 43 is changed, the filter plate 6 can slide off the trapezoidal protrusion 42 by itself, thereby avoiding the user from manually removing the filter plate 6.

[0028] The base plate 3 is also provided with a connecting assembly 5, which includes a rotating disk 51, a second connecting rod 52, a plug post 53, a connecting ring 54, a reset torsion spring 55 and a limit block 56. The rotating disk 51 is fixedly mounted on the end surface of the plug post 53, and both ends of the second connecting rod 52 are provided with connecting shafts. The second connecting rod 52 and the rotating disk 51 are movably connected through the connecting shaft of the second connecting rod 52. The plug post 53 is rotatably arranged on the base plate 3, and the connecting ring 54 is fixedly mounted on the plug post 53. The two ends of the reset torsion spring 55 are respectively fixedly connected to the connecting ring 54 and the base plate 3, and the limit block 56 is fixedly installed on the plug column 53, and a socket is provided on the filter box 1. The opening shape of the socket is consistent with the shape of the combination of the end face of the plug column 53 and the end face of the limit block 56, so that the plug column 53 and the limit block 56 can be inserted into the filter box 1, and the position of the base plate 3 can be limited on the filter box 1 by adjusting the position of the plug column 53 and the limit block 56. The distance between the connecting end of the second connecting rod 52 and the turntable 51 and the center of the turntable 51 is smaller than the radius of the turntable 51, ensuring that multiple turntables 51 can be linked by the second connecting rod 52 to achieve the effect of synchronous rotation.

[0029] Working principle: Use the connecting pipe 2 to connect the filter box 1 between the water source and the variable frequency water supply pipeline, and perform deep filtration through the multi-layer filter plates 6 inside the filter box 1 to prevent impurities in the water source from entering the variable frequency water supply pipeline and causing blockage, while also ensuring the quality of water supply.

[0030] When the filter plate 6 needs to be replaced, the turntable 51 fixedly connected to the plug post 53 is rotated, and the plug post 53 in a rotating state inside the base plate 3 will rotate, and the limit block 56 fixed on the plug post 53 will rotate synchronously until the limit block 56 rotates to the notch of the plug hole on the filter box 1, wherein the multiple turntables 51 are linked by three second connecting rods 52, and the base plate 3 can be removed from the filter box 1 at this time, and the movable block 41 is pushed, and the movable block 41 slides on the base plate 3 through the connecting block 49 fixedly connected thereto, and the connecting block 49 is fixedly connected to the rack 47 sliding on the base plate 3, so the movable block 41 will drive the rack 47 to slide together, and the rack 47 is meshed with the gear 48 fixed on the rotating shaft 44, and the sliding of the rack 47 will drive the gear 48 to rotate, and the rotating shaft 44 rotates synchronously, and the movable blocks 43 at both ends are respectively connected to the rotating shaft 44 and the plug block 43. Under the action of the connected first connecting rod 45, the plug block 43 will be pulled to slide towards the inside of the trapezoidal protrusion 42, so that the plug block 43 will be disengaged from the inside of the filter plate 6 and the restriction will be released. Because the contact surface between the filter plate 6 and the trapezoidal protrusion 42 is an inclined surface, the contaminated filter plate 6 will slide off the trapezoidal protrusion 42 at this time, and then a new filter plate 6 will be placed on the trapezoidal protrusion 42, and the movable block 41 will be released. Under the action of the auxiliary spring 46 fixedly connected to the plug block 43 and the trapezoidal protrusion 42 at both ends, the plug block 43 will be popped out and inserted into the inside of the filter plate 6 again to limit the position of the filter plate 6. At the same time, the rotating shaft 44 rotates in the opposite direction, prompting the rack 47 and the movable block 41 to return to the initial position, wherein the rack 47 is meshed with multiple gears 48 at the same time. Therefore, after the movable block 41 drives the rack 47 to slide, the positions of multiple plug blocks 43 can be changed to simplify the entire operation steps.

[0031] When the base plate 3 with the replaced filter plate 6 is assembled on the filter box 1, the turntable 51 is rotated to adjust the position of the limit block 56 so that it is inserted into the filter box 1 through the gap of the filter box 1 plug hole, and then the turntable 51 is loosened. The connecting ring 54 fixed on the plug post 53 is also connected to the base plate 3 by the reset torsion spring 55. Therefore, the reset torsion spring 55 will drive the plug post 53 to rotate, so that the limit block 56 and the gap of the filter box 1 plug hole are in a misaligned state, thereby locking the position of the base plate 3 on the filter box 1 for filtering.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
