Description

Technical Field

[0001] The utility model relates to the field of filters, in particular to a filter which is easy to clean and replace. Background Art

[0002] Pipelines are a common fluid transportation device. During transportation, in order to prevent the pipeline from being blocked, a filter is usually installed inside the pipeline to filter the fluid. However, after a period of use, the filter's flow capacity will decrease due to the increase in filtered matter. Since the pipeline itself is sealed, it needs to be removed and cleaned at this time, which is inconvenient to use.

[0003] After searching, Chinese patent announcement number: CN219023490U discloses a pipeline filter structure, including a horizontal tube body and an inclined tube body, one end of the horizontal tube body is a liquid inlet, and the other end of the horizontal tube body is a liquid outlet. The horizontal tube body is provided with an inclined fixing plate between the liquid inlet and the liquid outlet, and a filter portion is connected to the inclined fixing plate. One end of the filter portion faces the liquid inlet, and the other end of the filter portion is staggered with the liquid outlet. The inclined tube body and the filter portion are arranged coaxially, one end of the inclined tube body is connected to the horizontal tube body, and the other end of the inclined tube body is provided with an end cap. The filter portion includes, from top to bottom, an upper pressure ring, a fixing ring, a lower pressure ring, a filter cartridge, and a bottom cover. The upper pressure ring and the fixing ring are connected by a threaded connection. Both are replaceable parts and can be replaced if rusted, serving to replace the threaded connection of the inclined fixing plate, thereby making the replacement and installation of the filter cartridge of the filter more convenient.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figure 1 - Figure 3The filter element 31 is convenient to clean and replace, and comprises a water inlet pipe 1 for supplying water into the interior of the device, a water outlet pipe 2 for discharging the filtered water is fixedly connected to the right end of the water inlet pipe 1, and a filter assembly 3 is provided on the inner wall of the water inlet pipe 1 for filtering the water flow, and the filter assembly 3 comprises a sleeve 31 for accommodating a filter sleeve 32, and the sleeve 31 is inserted into the bottom end of the water inlet pipe 1, and the outer wall of the sleeve 31 is made of rubber. After the sleeve 31 is inserted into the interior of the water inlet pipe 1, the outer wall of the sleeve 31 can fit tightly against the inner wall of the water inlet pipe 1, and the inner wall of the sleeve 31 is provided with a cleaning assembly 4 for cleaning the filter sleeve 32, and the cleaning assembly 4 comprises a storage box 41 for accommodating an extrusion spring 44, and the storage box 41 is fixedly connected to the inner wall of the sleeve 31, and the right end of the water inlet pipe 1 is provided with a drain port 33 for allowing the filtered water to enter the outlet pipe 2.

[0034] Reference Figure 2 - Figure 4 The bottom end of the sleeve 31 is fixedly connected with a slide plate 35 for closing the bottom end of the sleeve 31. The bottom end of the slide plate 35 passes through and is rotatably connected with a rotating plate 34 for supporting the filter sleeve 32. The top of the rotating plate 34 is fixedly connected with the filter sleeve 32 for filtering the water flow. After the water flow enters the water inlet pipe 1, it needs to pass through the filter sleeve 32 before it can enter the water outlet pipe 2 through the drain port 33. The filter sleeve 32 is rotatably connected to the inner wall of the sleeve 31. The top of the filter sleeve 32 and the inner wall of the sleeve 31 are The rotation connection prevents water from passing through the filter sleeve 32 from the connection. The bottom end of the rotating plate 34 is fixedly connected with a handle 37 for facilitating the operator to move the rotating plate 34. The right end of the handle 37 passes through and is slidably connected with a block 38 for fixing the handle 37. The inner wall of the water inlet pipe 1 is provided with a sliding groove 39 for accommodating the block 38. The block 38 slides on the inner wall of the sliding groove 39. When the block 38 is stuck inside the sliding groove 39, the block 38 can slide inside it but cannot escape from the sliding groove 39.

[0035] Reference Figure 3 - Figure 5 The left end of the block 38 is fixedly connected to a fixing spring 311 for pushing the block 38. The left end of the fixing spring 311 is fixedly connected to the inner wall of the handle 37. The fixing spring 311 will always push the block 38 outward. The block 38 is set to be L-shaped, and the bottom end of the block 38 passes through and is slidably connected to the bottom end of the handle 37. By tossing the bottom end of the block 38, the block 38 can be driven to move left and right. The outer wall of the slide 35 is fixedly connected to a sealing ring 36 for increasing the sealing between the slide 35 and the inner wall of the water inlet pipe 1. The inner wall of the water inlet pipe 1 is provided with a sealing groove 310 near the bottom end of the drain outlet 33 for accommodating the sealing ring 36. The sealing ring 36 and the sealing groove 310 are adapted to each other. When the sealing ring 36 is stuck in the inside of the sealing groove 310, water will not be able to pass through the slide 35 from the outside of the slide 35.

[0036] Reference Figure 4 - Figure 6 The cleaning assembly 4 also includes a push plate 42 for driving the bristles 43 to move. The right end of the push plate 42 is fixedly connected to the bristles 43 for cleaning the filter holes of the filter sleeve 32. The left end of the push plate 42 is fixedly connected to an extrusion spring 44 for pushing the push plate 42. The left end of the extrusion spring 44 is fixedly connected to the inner wall of the storage box 41. The extrusion spring 44 will always push the push plate 42 outward, and the push plate 42 will drive the bristles 43 to be squeezed from the outside to the inside.

[0037] Working principle: When the filter sleeve 32 is clogged due to long-term use, the rotating handle 37 can be used to drive the rotating plate 34 to rotate. The rotation of the rotating plate 34 will drive the filter sleeve 32 to rotate synchronously. While the filter sleeve 32 rotates, the extrusion spring 44 will push the push plate 42 to drive the bristles 43 to squeeze and penetrate the filter holes on the outer wall of the filter sleeve 32. In this way, when the filter sleeve 32 rotates, the bristles 43 will push out the debris inside the filter holes, so that the filter sleeve 32 can restore its filtering ability.

[0038] When a lot of debris accumulates inside the filter sleeve 32, the block 38 can be pushed inward to drive the block 38 out of the sliding groove 39, and then the handle 37 can be pulled downward to drive the entire device to move downward and out of the water inlet pipe 1. In this way, the filter assembly 3 can be taken out and the garbage inside it can be cleaned. The entire device is more convenient to disassemble.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
