Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically to a filter element anti-detachment housing assembly and a filter. Background Technology

[0002] Filters are critical components in water treatment systems, and the stable connection between the filter element and the outlet channel directly affects filtration efficiency and equipment reliability. The filter element is typically designed within a housing, and is contained by the housing and end caps. Traditional technologies generally use an interference fit to achieve a mechanical connection between the filter element and the outlet channel, forming an initial seal through physical interference. However, this structure faces significant challenges during long-term operation: continuous water flow impact and pressure changes can cause the connecting parts to gradually loosen, especially in scenarios with sudden system pressure changes or significant water hammer effects. The housing and end caps may loosen, easily causing gaps or detachment between the filter element and the outlet channel, resulting in unfiltered water directly entering the outlet without passing through the filter element, causing filtration failure. Existing improvements often use adhesives to strengthen the connection interface, which can improve the bonding strength in the short term but introduces new problems. Filter elements need to be replaced after a period of use, but the cured adhesive significantly increases disassembly resistance. Maintenance requires the use of high temperatures or chemical solvents to destroy the adhesive layer, which is not only complex but may also damage the filter element structure.

[0003] Therefore, the inventors have proposed a filter element anti-detachment housing assembly and a filter to solve the above-mentioned technical problems. Utility Model Content

[0004] One objective of this utility model is to provide a filter element anti-detachment housing assembly for a filter, which aims to solve the problems of traditional interference fit filter elements being prone to loosening and detachment under water flow impact pressure, as well as the difficulties in disassembly and maintenance caused by adhesive fixing methods; the second objective is to propose a filter.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A filter cartridge anti-detachment housing assembly includes a housing;

[0007] The mounting part is disposed inside the outer casing. The mounting part has a through groove and a mounting groove. The through groove is connected to the mounting groove. The through groove is arranged along the axial direction of the mounting part, and the mounting groove is arranged along the radial direction of the mounting part.

[0008] A connector for connecting to the filter element of a filter, wherein the end of the connector away from the filter element can extend into or out of the through groove along the axial direction of the mounting portion;

[0009] The abutment is movably disposed within the mounting groove and can extend radially into the through groove along the mounting portion. The connector and the abutment can engage or disengage with each other.

[0010] According to the above technical solution, one end of the connector is connected to the filter element, and the other end can be inserted into the through groove of the mounting part. The abutment is movably set in the mounting groove that communicates with the through groove. When the connector is inserted into the through groove, the abutment is squeezed and moves along the second direction of the mounting groove. After the connector is in place, the abutment and the connector are locked together to prevent the connector from coming out.

[0011] Furthermore, the connector includes a shaft, a guide cone, and a sliding cone, with one end of the shaft fixedly connected to the guide cone and the other end of the shaft connected to the filter element;

[0012] The sliding cone is sleeved on the shaft, and the sliding cone can slide along the axial direction of the shaft.

[0013] According to the above technical solution, during installation, the shaft drives the guide cone to insert into the through groove. The conical structure of the guide cone guides the abutment to expand outward. Simultaneously, the sliding cone is attracted by the magnetic force of the magnetic sleeve and slides along the shaft axis, forming an annular gap with the guide cone. When the guide cone is fully inserted into the through groove, the abutment is locked into the gap by the elastic element, forming a mechanical lock. During disassembly, the filter element is pushed to the left. Due to the existence of the inclined guide surface of the locking block, the locking block abuts against the sliding cone. At this time, the filter element is pulled to the right. The locking block drives the sliding cone to move to the left. When the sliding cone moves to the guide cone, it can no longer move to the left. The contact between the locking block and the sliding cone changes to the contact between the locking block and the guide cone. Continuing to move to the left, the filter element is disengaged, realizing quick installation and disassembly of the filter element.

[0014] Furthermore, a magnetic sleeve is fixedly provided on the shaft, and the sliding cone is disposed between the magnetic sleeve and the guide cone. The magnetic sleeve has a tendency to drive the sliding cone closer to the magnetic sleeve.

[0015] When the sliding cone moves away from the guide cone, a gap is formed between the sliding cone and the guide cone.

[0016] According to the above technical solution, the magnetic sleeve is fixed to the surface of the shaft, generating a continuous magnetic attraction force on the sliding cone sleeved on the shaft, so that the sliding cone has a tendency to always fit the magnetic sleeve. A gap is formed between the sliding cone and the guide cone, which provides locking space for the subsequent insertion of the abutment. At the same time, the magnetic force ensures that the sliding cone will not undergo unexpected displacement due to vibration or water flow disturbance in the free state, thus ensuring the reliability of the connection.

[0017] Furthermore, the mounting groove includes a first mounting hole and a second mounting hole, the first mounting hole being connected to the second mounting hole, and the second mounting hole being connected to the through groove.

[0018] Furthermore, the abutment includes a locking block slidably disposed within the second mounting hole. An inclined guide surface is formed on the side of the locking block near the sliding cone. The inclined guide surface forms an acute angle with the axis of the shaft, which is used to guide the locking block to move along the mounting groove direction to achieve axial locking or unlocking.

[0019] Furthermore, a connecting post is fixedly connected to the card block, and the connecting post passes through the first mounting hole and connects to the limit block;

[0020] An elastic element is fitted onto the connecting post. One end of the elastic element is connected to the top of the first mounting hole, and the other end of the elastic element is connected to the locking block.

[0021] According to the above technical solution, during installation, as the connector is inserted into the through slot, the locking block slides outward along the second mounting hole position under the pressure of the guide cone's conical surface. The connecting column compresses the elastic element to store energy. When the gap between the sliding cone and the guide cone reaches the locking block position, the elastic element releases energy to push the locking block back to its original position, thus locking into the gap and forming an axial lock. During disassembly, the filter element is continued to be pushed until the sliding cone contacts the magnetic sleeve. The locking block has an inclined guide surface and climbs along the outer circumference of the sliding cone to its surface. At this time, the filter element is pulled to the right, and the sliding cone overcomes the magnetic force and moves to the left.

[0022] Furthermore, the elastic element is a helical compression spring or a rubber elastic sleeve.

[0023] Furthermore, the shaft is a hollow structure with openings at both ends.

[0024] According to the above technical solution, one end of the shaft is connected to the inside of the filter element, and the other end extends into the through groove of the mounting part. When the water treatment system is running, the water to be filtered enters the shell from the inlet channel, permeates through the outside of the filter element to the inside to complete the filtration, and after the pure water enters the central area of ​​the filter element, it flows directly through the hollow inner cavity of the shaft to the through groove, and is finally discharged through the outlet channel connected to the through groove, ensuring the efficient and stable operation of the filtration system.

[0025] On the other hand, this application also proposes a filter, including a filter element and a filter element anti-detachment housing assembly of the aforementioned filter; the filter element is disposed in the housing, and the housing includes a shell body and an end cap; the end cap is detachably connected to the shell body, and the end cap is provided with an inlet channel and an outlet channel.

[0026] Furthermore, the mounting part is fixedly connected to the end cover, and the shaft extends into the interior of the filter element and is connected to the filter element.

[0027] The filter element is easily maintained through a detachable connection between the end cap and the housing. During installation, after the filter element is placed into the housing, the shaft extends into the filter element to form a rigid fixation. The mounting part is fixed to the inside of the end cap. When the end cap and housing are closed, the guide cone of the connector inserts into the through groove of the mounting part, triggering the locking block of the abutment part to form a mechanical lock with the sliding cone, ensuring that the filter element remains axially fixed under high-pressure water flow or water hammer impact. During filtration, raw water enters the housing through the water inlet channel of the end cap, passes through the outer wall of the filter element to complete purification, and the purified water gathers inside the filter element to the hollow shaft, and finally flows through the through groove into the water outlet channel of the end cap for discharge. During disassembly, after opening the end cap, continue to push the filter element and pull it out in the opposite direction to achieve non-destructive replacement, balancing connection reliability and maintenance convenience.

[0028] The beneficial effects of this utility model are:

[0029] In this invention, during filter element installation, after the guide cone pushes open the abutment, the magnetic sleeve attracts the sliding cone to form a locking gap. The elastic element drives the locking block to precisely embed into the gap to achieve rigid locking, which can effectively resist axial loosening caused by water pressure fluctuations, water hammer effect, and vibration. Disassembly is convenient and simple, and releasing the lock does not require destructive operation, which not only ensures the reliability of the connection under high pressure environment, but also avoids the risk of disassembly damage caused by traditional adhesives. The structure is compact and highly practical.

Detailed Implementation

[0040] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0041] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the illustrations only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0042] This embodiment proposes a filter element anti-detachment housing assembly, such as... Figure 1 and Figure 2 As shown, it includes a housing 7 and a mounting part 1, a connector 2 and abutment 3. The mounting part 1 is disposed inside the housing 7. The mounting part 1 has a through groove 11 and a mounting groove 12. The through groove 11 and the mounting groove 12 are connected. The through groove 11 is arranged along the axial direction of the mounting part 1, and the mounting groove 12 is arranged along the radial direction of the mounting part 1.

[0043] Preferably, there are two mounting slots 12; the connector 2 is used to connect with the filter element 4 of the filter, and the end of the connector 2 away from the filter element 4 (i.e., Figure 1The left end of the connecting member 2 can extend into or be pulled out of the through groove 11; there are two abutting members 3, which are slidably disposed in the two mounting grooves 12 and can extend into the through groove 11 radially along the mounting part 1. The connecting member 2 and the abutting member 3 can engage or disengage with each other.

[0044] When the filter element 4 needs to be assembled, the connector 2 is inserted into the through groove 11 of the mounting part 1 along the axial direction of the mounting part 1. When the left end of the connector 2 enters the through groove 11, the abutment 3 engages with the connector 2 to limit the movement, and the filter element 4 is firmly locked on the mounting part 1. When the filter element 4 needs to be disassembled, the filter element 4 is pushed to move so that the connector 2 and the abutment 3 are disengaged. At this time, the connector 2 is unrestrained and can be smoothly pulled out from the through groove 11 along the axial direction of the mounting part 1, and the filter element 4 is disassembled. The entire process achieves the quick assembly and disassembly of the filter element 4 through the engagement or disengagement of the abutment 3 and the connector 2, ensuring that the filter element 4 can maintain a long-term stable connection under complex working conditions.

[0045] As a preferred embodiment, such as Figure 3 As shown, the connector 2 includes a shaft 21, a guide cone 22, and a sliding cone 23. The guide cone 22 has a frustoconical structure with a smaller left side and a larger right side, and the sliding cone 23 has a frustoconical structure with a larger right side and a smaller left side. The left end of the shaft 21 is fixedly connected to the guide cone 22, and the right end of the shaft 21 is connected to the filter element 4. The sliding cone 23 is sleeved on the shaft 21, and the sliding cone 23 can slide along the axial direction of the shaft 21. The maximum diameter of the guide cone 22 is adapted to the inner diameter of the through groove 11.

[0046] As a preferred embodiment, such as Figure 3 As shown, a magnetic sleeve 24 is fixedly installed on the shaft 21, and a sliding cone 23 is disposed between the magnetic sleeve 24 and the guide cone 22. The sliding cone 23 can be a plastic part, and a magnet can be embedded in the sliding cone 23. The magnetic sleeve 24 has a tendency to drive the sliding cone 23 closer to the magnetic sleeve 24. When the sliding cone 23 moves away from the guide cone 22, a gap 25 is formed between the sliding cone 23 and the guide cone 22.

[0047] In this embodiment, the magnetic sleeve 24 is fixed to the shaft 21, generating a continuous magnetic attraction force on the sliding cone 23 sleeved thereon, so that the sliding cone 23 has a tendency to always fit the magnetic sleeve 24. A gap 25 is formed between the sliding cone 23 and the guide cone 22. This gap 25 provides locking space for the subsequent insertion of the abutment 3. At the same time, the magnetic force ensures that the sliding cone 23 will not undergo unexpected displacement due to vibration or water flow disturbance in the free state, thus ensuring the reliability of the connection.

[0048] As a preferred embodiment, such as Figure 2As shown, the mounting groove 12 includes a first mounting hole 121 and a second mounting hole 122. The first mounting hole 121 is connected to the second mounting hole 122, and the second mounting hole 122 is connected to the through groove 11. The first mounting hole 121 and the second mounting hole 122 can be formed using an adjustable boring tool (or an internal turning tool). First, a small-diameter hole is drilled through the shaft. After the tool enters, the tool head position is adjusted for cutting. Alternatively, the tool can enter from the through groove 11, and the tool head position is adjusted for cutting to form the first mounting hole 121 and the second mounting hole 122. The machining process for forming the first mounting hole 121 and the second mounting hole 122 is a conventional technique in the relevant technical field.

[0049] like Figures 3 to 8 As shown, the abutment 3 includes a locking block 31 that is slidably disposed in the second mounting hole 122. An inclined guide surface is formed on the locking block 31, and the inclined guide surface forms an acute angle with the axis of the shaft 21, which is used to guide the locking block 31 to move along the mounting groove 12 to achieve locking or unlocking.

[0050] A connecting post 32 is fixedly connected to the card block 31. The connecting post 32 passes through the first mounting hole 121 and is connected to a limit block 33. The purpose of the limit block 33 is to prevent the connecting post 32 from disengaging from the first mounting hole 121 and to play a limiting role.

[0051] An elastic element 321 is fitted onto the connecting post 32. The elastic element 321 is a helical compression spring or a rubber elastic sleeve. The top end of the elastic element 321 is connected to the top of the first mounting hole 121, and the bottom end of the elastic element 321 is connected to the locking block 31. During installation, as the connecting piece 2 is inserted into the through groove 11, the locking block 31 is pressed outward by the conical surface of the guide cone 22. The locking block 31 compresses the elastic element 321 to store energy. When the gap 25 between the sliding cone 23 and the guide cone 22 reaches the position of the locking block 31, the elastic element 321 releases energy to push the locking block 31 into the gap 25 to form an axial lock, thereby realizing the rapid installation of the filter element 4.

[0052] As a preferred implementation scheme, such as Figure 4 As shown, the shaft 21 and guide cone 22 are hollow structures with openings at both ends. When the filter element 4 is installed inside the housing 7, one end of the shaft 21 communicates with the inside of the filter element 4, and the other end extends into the through groove 11 of the mounting part 1. When the water treatment system is running, the water to be filtered / raw water enters the housing 5, permeates through the outside of the filter element 4 to the inside to complete filtration, and after the pure water enters the central area of ​​the filter element 4, it flows directly through the hollow inner cavity of the shaft 21 to the through groove 11, and is finally discharged through the through groove 11, ensuring the efficient and stable operation of the filtration system.

[0053] The installation and removal of the filter element's anti-detachment structure is achieved through a combination of mechanical engagement and magnetic assistance, comprising five states: such as Figure 3As shown, in state one: the filter element 4 is placed into the housing 5, the right end of the shaft 21 is fixedly connected to the filter element 4, and the mounting part 1 is fixed inside the end cover 6. At this time, the guide cone 22 of the connecting piece 2 extends into the through groove 11, and the locking block 31 of the abutting piece 3 abuts against the guide cone 22; Figure 5 As shown, in state two: continue pushing the filter element 4 to the left. When the gap 25 reaches the position of the locking block 31, the elastic element 321 releases energy to push the locking block 31 into the gap 25 to form an axial lock (corresponding to...). Figure 5 The filter element 4 and the mounting part 1 are rigidly connected; for example... Figure 6 As shown, in state three: Continuing to push the filter element 4 to the left, the shaft 21, sliding cone 23, and magnetic sleeve 24 all move to the left. Under the action of the sliding cone 23, the inclined guide surface of the locking block 31 moves radially outward along the mounting part 1. At this time, the bottom of the locking block 31 abuts against the outer circumferential surface of the sliding cone 23 (corresponding to...). Figure 6 ).like Figure 7 As shown in state four, when the filter element 4 is pulled to the right, the shaft 21, guide cone 22, and magnetic sleeve 24 move to the right. Due to the elastic effect of the elastic element 321, the position of the sliding cone 23 does not change, and the guide cone 22 moves to the right and contacts the sliding cone 23 (corresponding to...). Figure 7 );like Figure 8 As shown, in state five: after the sliding cone 23 contacts the guide cone 22, the filter element is pulled to the right. The locking block 31 slides from the sliding cone 23 to the guide cone 22. The filter element 4 is pulled further, and the guide cone 22 moves to the right. At this time, the locking block 31 slides along the guide cone 22. When the filter element 4 is pulled to the right, the guide cone 22 is completely disengaged from the locking block 31. The guide cone 22 is completely pulled out from the through groove 11 of the mounting part 1, completing the quick disassembly.

[0054] On the other hand, this application also proposes a filter, a filter element 4, and a filter element anti-detachment housing assembly for the aforementioned filter; the filter element 4 is disposed inside the housing 7, the housing 7 includes a housing body 5 and an end cap 6, the end cap 6 is detachably connected to the housing body 5, such as the end cap 6 being threadedly connected to the housing body 5; the end cap 6 has an inlet channel 61 and an outlet channel 62. The mounting part 1 is fixedly connected to the end cap 6, and the shaft 21 extends into the interior of the filter element 4 and is fixedly connected to the filter element 4. During installation, after the filter element 4 is placed into the housing body 5, the shaft 21 extends into the interior of the filter element 4 to form a rigid fixation, the mounting part 1 is fixed to the inside of the end cap 6, the guide cone 22 of the connecting member 2 is inserted into the through groove 11 of the mounting part 1, triggering the locking block 31 of the abutment member 3 and the sliding cone 23 to form a mechanical lock, ensuring that the filter element 4 remains axially fixed under high-pressure water flow or water hammer impact. During the filtration process, raw water enters the housing 5 through the inlet channel 61 of the end cover 6, passes through the outer wall of the filter element 4 to complete purification, and the purified water is collected inside the filter element 4 to the hollow shaft 21, and finally discharged through the outlet channel 62 of the end cover 6 via the through groove 11. During disassembly, after opening the end cover 6, the filter element 4 is pushed to disengage the locking block 31 along the sliding cone 23, thus balancing connection reliability and ease of maintenance.
