A filter cartridge convenient to disassemble and clean

Abstract

This application relates to the technical field of filter elements, and in particular to a filter element that is easy to disassemble and clean, including a housing and a limiting mechanism. The limiting mechanism includes: a fixed plate disposed on the top of the housing, and a turntable rotatably connected to the top of the fixed plate; in this solution, by rotating the turntable, the convex ring at the bottom of the turntable rotates within the convex groove of the fixed plate. The rotation of the turntable causes the fixed post to rotate, thereby rotating the limiting plate from the limiting groove into the through hole, releasing the lock.

Description

Technical Field

[0001] This application relates to the technical field of filter elements, and in particular to a filter element that is easy to disassemble and clean. Background Technology

[0002] A filter element is a component used to separate solid particles from liquids or gases. It is widely used in industrial and civilian fields. However, after a period of use, the filter element will turn yellow and accumulate dirt. At this time, people need to clean the filter element in time to ensure the filtration effect.

[0003] In existing technologies, some solutions involve disassembling various parts such as faucets using tools like screwdrivers and wrenches before removing the filter element for cleaning. However, these solutions still have some problems. For example, this method is too cumbersome to disassemble and cannot quickly remove the filter element for cleaning. Furthermore, this disassembly method may confuse users without installation experience about the order of disassembly (such as accidentally removing key seals) or cause deformation of parts due to improper force control (such as breaking plastic nuts), thus failing to meet people's daily usage needs.

[0004] Therefore, in order to solve the above problems, this application provides a filter element that is easy to disassemble and clean. Utility Model Content

[0005] To address the problem that filter elements are not easy to disassemble and clean quickly, this application provides a filter element that is easy to disassemble and clean.

[0006] This application provides a filter element that is easy to disassemble and clean, including a housing and a limiting mechanism, wherein the limiting mechanism includes:

[0007] A fixed plate is provided on the top of the outer shell, and a turntable is rotatably connected to the top of the fixed plate. Multiple through holes are provided through the fixed plate and the top of the outer shell. The fixed plate and the through holes on the top of the outer shell are coaxially arranged. A limiting groove is provided through one side of the through hole on the top of the outer shell. The multiple through holes are connected to the limiting groove. Fixed posts are fixedly connected to the bottom of the turntable near the bottom of the multiple through holes. A limiting plate is provided at the bottom of the multiple fixed posts. The multiple fixed posts are fixedly connected to one side of the top of the limiting plate. The multiple limiting plates are adapted to the through holes. The multiple limiting plates are slidably engaged with the limiting groove.

[0008] A locking mechanism is provided on one side of the fixed plate.

[0009] Preferably, screws are provided on all four sides of the top of the turntable, and multiple screws penetrate the turntable, the fixed post, and the limiting plate. Multiple screws are threadedly connected to the turntable and the fixed post, and the bottom end of multiple screws is threadedly connected to the limiting plate.

[0010] Preferably, a knob is fixedly installed at the top end of the screw, and the bottom end of the screw contacts the bottom of the through hole on the outer casing.

[0011] Preferably, a convex ring is fixedly connected to the bottom of the turntable, and a convex groove is formed through the top of the fixed disk, with the convex ring and the convex groove being rotatably connected.

[0012] Preferably, the bottom of the fixing plate is fixedly connected to the filter element body.

[0013] Preferably, the locking mechanism includes:

[0014] A connecting cylinder is fixedly installed on one side inside the fixed disk. The connecting cylinder is located in the middle of two through holes. An elastic element is provided inside the connecting cylinder. A connecting post is provided on the side of the connecting cylinder near the convex groove. The connecting post is elastically connected to the connecting cylinder through the elastic element. The connecting post passes through one side of the fixed disk and slides with the fixed disk. Multiple limiting holes are opened through the outer surface of the convex ring. The connecting post is adapted to one of the limiting holes.

[0015] Preferably, a pull rope is fixedly connected to the side of the connecting column away from the convex groove. The pull rope passes through the connecting cylinder and the fixed plate, and the pull rope slides with the connecting cylinder and the fixed plate. One end of the pull rope is hinged with a pull ring.

[0016] Preferably, the fixing plate has a through-hole groove near the top of the pull ring, and the pull ring is adapted to the placement groove.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0018] 1. In this utility model, by rotating the turntable, the convex ring at the bottom of the turntable rotates within the convex groove of the fixed plate. The rotation of the turntable causes the fixed post to rotate, thereby rotating the limiting plate. The limiting plate rotates from the limiting groove into the through hole, releasing the lock. Then, the fixed plate is lifted upwards, causing the filter element body to move out of the housing for cleaning. No screwdrivers, wrenches, or other tools are needed. Whether it is the elderly, children, or users lacking installation experience, they can easily get started. This solves the problem of complex operation caused by the reliance on tools in traditional filter elements. At the same time, the coaxial design of the fixed plate and the through hole of the housing ensures the stability of the movement path of the limiting plate and the fixed post, reducing the risk of jamming.

[0019] 2. In this utility model, rotating the knob drives the screw to rotate upward, releasing the lock between the limiting plate and the limiting groove. Through the rotational engagement of the limiting plate and the limiting groove, plus the screw pressing, the screw forms a rigid mechanical lock, resisting the radial force (such as water flow impact, equipment vibration) during filter element operation, preventing the filter element from swaying horizontally. The pull ring drives the pull rope to move, and the pull rope drives the connecting post into the connecting cylinder, forming an axial lock. When the connecting post is embedded in the connecting cylinder, it restricts the axial displacement of the convex ring (bottom of the turntable), preventing the filter element from loosening or falling off in the vertical direction (such as lifting during installation and disassembly, gravity). The dual locking works together from both radial and axial dimensions, making it especially suitable for high-pressure, high-frequency use scenarios (such as kitchen faucets, commercial coffee machines). Even with long-term use, it can remain stable, reducing the risk of water leakage, filter element displacement, etc. Attached Figure Description

[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0029] Example 1, such as Figure 1-6 As shown, this utility model provides a filter element that is easy to disassemble and clean, including a housing 1, a limiting mechanism, and a locking mechanism;

[0030] The limiting mechanism includes: a fixed plate 2 is provided on the top of the outer shell 1, and a turntable 3 is rotatably connected to the top of the fixed plate 2. Multiple through holes 9 are provided through both the fixed plate 2 and the top of the outer shell 1. The fixed plate 2 and the through holes 9 on the top of the outer shell 1 are coaxially arranged. A limiting groove 11 is provided through one side of each through hole 9 on the top of the outer shell 1. All through holes 9 are connected to the limiting groove 11. Fixed posts 7 are fixedly connected to the bottom of the turntable 3 near the bottom of each of the multiple through holes 9. Limiting plates 5 are provided at the bottom of each of the multiple fixed posts 7. Each of the multiple fixed posts 7 is fixedly connected to one side of the top of the limiting plate 5. Each of the multiple limiting plates 5 is adapted to the through holes 9 and slides in cooperation with the limiting groove 11. Both the multiple limiting plates 5 and the limiting groove 11 are arc-shaped. The top of the turntable 3... Each of the four sides is equipped with a screw 12, with a knob 4 fixedly installed at the top of each screw 12. Multiple screws 12 pass through the turntable 3, the fixed post 7, and the limiting plate 5, and are threadedly connected to the turntable 3 and the fixed post 7. The bottom ends of multiple screws 12 are threadedly connected to the limiting plate 5, and the bottom of each screw 12 contacts the bottom of the through hole 9 on the outer casing 1. A convex ring 8 is fixedly connected to the bottom of the turntable 3. A convex groove 10 is formed through the top of the fixed plate 2, and the convex ring 8 is rotatably connected to the convex groove 10. A filter element body 6 is fixedly connected to the bottom of the fixed plate 2. The threads between the screws 12 and the turntable 3, the fixed post 7, and the limiting plate 5 can achieve self-locking. The self-locking condition depends on the helix angle, the coefficient of friction, and the load applied. The self-locking condition can be calculated using the following formula: Self-locking condition = Coefficient of friction × tan(helix angle) ≥ 1. When this condition is met, the threaded connection is self-locking. The above content refers to existing technology. In practical applications, the corresponding self-locking angle can be set according to the friction coefficient of the material, which will not be elaborated here.

[0031] In this embodiment, rotating knob 4 causes screw 12 to rotate upwards, releasing the lock between the limiting plate 5 and the limiting groove 11. Then, rotating turntable 3 causes the convex ring 8 at the bottom of turntable 3 to rotate within the convex groove 10 of fixed plate 2, thereby causing the fixing posts 7 on all four sides of turntable 3 to rotate the limiting plate 5. The limiting plate 5 rotates out of the limiting groove 11 and into the through hole 9. The through hole 9 at the top of the outer shell 1 is coaxial with the through hole 9 on the fixed plate 2, so it does not affect the rotation of the fixing post 7 within the through hole 9 of the fixed plate 2. Then, lifting the fixed plate 2 causes the filter element body 6 to move out of the outer shell 1. The filter element body 6 is cleaned. After cleaning, the through hole 9 on the fixing plate 2 is aligned with the through hole 9 at the top of the outer shell 1. Then, the limiting plate 5 is placed into the through hole 9 at the top of the outer shell 1, and the filter element body 6 is placed inside the outer shell 1. Then, the turntable 3 is rotated, and the turntable 3 drives the fixing column 7 to rotate. The fixing column 7 drives the limiting plate 5 to rotate. Multiple limiting plates 5 rotate to one side, so that one side of multiple limiting plates 5 enters the limiting groove 11. At this time, the fixing column 7 contacts the side of the through hole 9. Then, the knob 4 is rotated, and the knob 4 drives the screw 12 to rotate. The screw 12 contacts the surface of the through hole 9 downward, thereby fixing the limiting plate 5 in the limiting groove 11.

[0032] Example 2, as Figure 1-6 As shown, the locking mechanism includes: a connecting cylinder 15 fixedly installed on one side inside the fixed plate 2, the connecting cylinder 15 being located in the middle of two through holes 9, an elastic element 16 being provided inside the connecting cylinder 15, a connecting post 14 being provided on the side of the connecting cylinder 15 near the convex groove 10, the connecting post 14 being elastically connected to the connecting cylinder 15 through the elastic element 16, the connecting post 14 penetrating one side of the fixed plate 2, the connecting post 14 slidingly engaging with the fixed plate 2, a plurality of limiting holes 13 being provided through the outer surface of the convex ring 8, the connecting post 14 being adapted to one of the limiting holes 13, a pull rope 17 being fixedly connected on the side of the connecting post 14 away from the convex groove 10, the pull rope 17 penetrating the connecting cylinder 15 and the fixed plate 2, the pull rope 17 slidingly engaging with the connecting cylinder 15 and the fixed plate 2, a pull ring 18 being hinged to one end of the pull rope 17, a placement groove 19 being provided through the top of the fixed plate 2 near the pull ring 18, the pull ring 18 being adapted to the placement groove 19.

[0033] In this embodiment, the pull ring 18 is rotated out of the placement groove 19 and pulled. The pull ring 18 drives the pull rope 17 to move. The pull rope 17 drives the connecting post 14 into the connecting cylinder 15, releasing the lock on the convex ring 8. At this time, the turntable 3 can be rotated, so that the turntable 3 drives the fixing post 7 and the limiting plate 5 to rotate. After the turntable 3 and the limiting plate 5 are fixed in position, the pull ring 18 can be released. The pull ring 18 drives the connecting post 14 into the limiting hole 13 on the outer surface of the convex ring 8, limiting the convex ring 8, thereby fixing the turntable 3 so that it no longer rotates. Then, the pull ring 18 is rotated upward so that the pull ring 18 enters the placement groove 19.

[0034] Working principle: In use, knob 4 can be rotated, which drives screw 12 to rotate upward, releasing the lock between limit plate 5 and limit groove 11. Then, pull ring 18 is rotated out from placement groove 19 and pulled. Pull ring 18 drives pull rope 17 to move. Pull rope 17 drives connecting post 14 into connecting cylinder 15, releasing the lock on convex ring 8. Rotate turntable 3. The convex ring 8 at the bottom of turntable 3 rotates in the convex groove 10 of fixed plate 2, thereby causing the fixed posts 7 on all four sides of turntable 3 to rotate. The limiting plate 5 rotates out of the limiting groove 11 and enters the through hole 9. The through hole 9 at the top of the outer shell 1 is coaxial with the through hole 9 on the fixed plate 2, so it will not affect the rotation of the fixed column 7 in the through hole 9 of the fixed plate 2. The pull ring 18 is released, and the pull ring 18 drives the connecting column 14 into the limiting hole 13 on the outer surface of the convex ring 8, limiting the convex ring 8 and fixing the turntable 3 so that it no longer rotates. Then the fixed plate 2 is lifted upward, and the fixed plate 2 drives the filter element body 6 to move out of the outer shell 1, so that the filter element... The filter element body 6 is cleaned. After cleaning, the through hole 9 on the fixing plate 2 is aligned with the through hole 9 at the top of the outer shell 1. Then, the limiting plate 5 is placed into the through hole 9 at the top of the outer shell 1, and the filter element body 6 is placed inside the outer shell 1. Then, the pull ring 18 is pulled, which moves the pull rope 17. The pull rope 17 moves the connecting post 14 into the connecting cylinder 15, releasing the lock on the convex ring 8. The turntable 3 is rotated, which drives the fixing post 7 to rotate. The fixing post 7 drives the limiting plate 5 to rotate. Multiple limiting plates 5 rotate to one side, so that multiple limiting plates... One side of plate 5 enters the limiting groove 11. At this time, the fixing post 7 contacts the side of the through hole 9. Then, the pull ring 18 is released. The pull ring 18 drives the connecting post 14 into the limiting hole 13 on the outer surface of the convex ring 8 to limit the convex ring 8, thereby fixing the turntable 3 and preventing it from rotating. The pull ring 18 is rotated upward so that it enters the placement groove 19. Then, the knob 4 is rotated. The knob 4 drives the screw 12 to rotate. The screw 12 contacts the surface of the through hole 9 downward, thereby fixing the limiting plate 5 in the limiting groove 11.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
