Description

Technical Field

[0001] This utility model relates to the field of machinery, and in particular to filters, specifically a water filter structure that is easy to disassemble and install. Background Technology

[0002] Water filters are widely used devices in homes, industries, and public facilities for purifying water sources. They remove impurities, pollutants, and harmful bacteria from water through physical, chemical, or biological methods to ensure the safety and cleanliness of the water supply and meet various water needs. As people's concern for water safety continues to grow, the application of water filters is becoming increasingly common, playing a vital role in improving people's quality of life and promoting the effective use of water resources.

[0003] However, water filters require regular maintenance during long-term use to ensure their filtration efficiency and lifespan. This maintenance includes cleaning or replacing the filter media and checking the equipment's operation. Failure to maintain in a timely manner can lead to filter clogging, performance degradation, or malfunction, negatively impacting water quality. In existing technologies, water filters are generally installed vertically, but in some scenarios, horizontal installation is necessary, which conventional structures cannot support. Furthermore, conventional water filters use fasteners to connect the end caps and the filter housing; in dimly lit environments, these fasteners are easily lost during disassembly or maintenance, hindering the process. For users and maintenance personnel, this not only increases the difficulty of maintenance but may also lead to filter damage or extended maintenance time, thus affecting the efficiency and reliability of the entire water system. Utility Model Content

[0004] The purpose of this utility model is to provide a water filter structure that is easy to disassemble and install. This water filter structure is designed to solve the technical problem that water filters in some scenarios are not easy to install and maintain in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A water filter structure that is easy to disassemble and install includes a hollow filter barrel. A handle is provided on the outer periphery of the bottom of the barrel, and an end cap is provided on the top of the barrel. An inlet pipe and an outlet pipe are provided inside the end cap. Two inlet ports and two outlet ports are provided on the upper side of the end cap. The inlet ports are connected to the inlet pipe, and the outlet ports are connected to the outlet pipe. A mounting bracket is provided on the upper side of the end cap. The mounting bracket is provided with a first mounting hole and a second mounting hole. The first mounting hole is arranged along the axial direction of the barrel, and the second mounting hole is arranged along the radial direction of the barrel. A filter element is arranged in the inner cavity of the barrel. The top of the filter element is connected to the bottom of the end cap, and the filter element is connected to the inlet pipe. A plurality of anti-fall-off limiting mechanisms are provided circumferentially between the top of the barrel and the end cap. At least one axially reinforcing support structure is provided between the outer wall of the barrel and the end cap.

[0007] Furthermore, the anti-fall-off limiting mechanism includes an upper ring and a lower ring. The upper ring is disposed on the outer periphery of the end cap, and the lower ring is disposed on the outer periphery of the top of the barrel body. A plurality of upper blocks are evenly arranged along the circumferential direction on the outer periphery of the upper ring, and a plurality of lower blocks are evenly arranged along the circumferential direction on the outer periphery of the lower ring. The number of upper blocks and lower blocks is the same. The lower blocks are disposed below the upper blocks. A threaded hole is provided in the center of the upper block, and a through hole is provided in the center of the lower block. The threaded hole and the through hole are coaxially aligned. The lower end is recessed upwards to form a positioning groove. The lower block is also provided with an exit groove. One end of the exit groove is connected to the outside of the side of the lower block, and the other end of the exit groove is connected to the through hole and the side of the positioning groove. A limit screw is provided in the threaded hole and the through hole. The limit screw has an external thread on its shank. The external thread and the threaded hole are matched. The head of the limit screw is set in the positioning groove. A limit block is provided at the other end of the limit screw. The width of the exit groove is greater than or equal to the outer diameter of the limit screw.

[0008] Furthermore, the support structure includes a first positioning piece, a second positioning piece, a third positioning piece, and an L-shaped limiting rod. The first positioning piece is disposed on the side of the end cap, the second and third positioning pieces are respectively disposed on the outer wall of the barrel, and the third positioning piece is disposed below the second positioning piece. The first and second positioning pieces are respectively provided with limiting holes, and the third positioning piece is provided with a limiting groove. The limiting groove has an opening in the direction of the outer side of the barrel. The long section of the limiting rod passes through the two limiting holes axially, and the short section of the limiting rod is disposed in the limiting groove.

[0009] Furthermore, both ends of the limiting rod are hexagonal.

[0010] Working principle:

[0011] Water filters are typically connected to end caps via mounting brackets, and the end caps are connected to the filter cartridge and the housing. This device features two sets of perpendicular mounting holes on the mounting bracket, allowing the housing to be installed vertically or horizontally. The support structure provides further support for the horizontally positioned end cap and housing.

[0012] The limiting mechanism of this device retains the fasteners used to connect the end cap and the barrel body on the end cap. Even if the fasteners are in a loose state, they will not fall off. This structure simplifies the disassembly and installation operation, while also reliably storing the fasteners.

[0013] The limit rod of this device can be used as an Allen wrench to directly adjust the fasteners at each connection point, which facilitates daily inspection and maintenance.

[0014] Compared with the prior art, the beneficial effects of this utility model are: it provides multiple installation methods for the tank body, multiple connection methods for water inlet and outlet pipes, preserves the fasteners connecting the end cap and the tank body, and optimizes the operation method for disassembling and maintaining the tank body.

[0027] Example 1

[0028] Please see Figure 1 , Figure 2 , Figure 4 This utility model provides a technical solution:

[0029] A water filter structure that is easy to disassemble and install includes a hollow filter barrel 1. A handle 2 is provided on the outer periphery of the bottom of the barrel 1. An end cap 3 is provided on the top of the barrel 1. An inlet pipe and an outlet pipe are provided inside the end cap 3. Two inlet ports 31 and two outlet ports 32 are provided on the upper side of the end cap 3. The inlet ports 31 are connected to the inlet pipe, and the outlet ports 32 are connected to the outlet pipe. A mounting bracket 4 is provided on the upper side of the end cap 3. The mounting bracket 4 is provided with a first mounting hole 41 and a second mounting hole 42. The first mounting hole 41 is arranged along the axial direction of the barrel 1, and the second mounting hole 42 is arranged along the radial direction of the barrel 1. A filter element 5 is provided in the inner cavity of the barrel 1. The top of the filter element 5 is connected to the bottom of the end cap 3. The filter element 5 is connected to the inlet pipe. A plurality of anti-fall-off limiting mechanisms are provided between the top of the barrel 1 and the end cap 3 in the circumferential direction. At least one axial reinforcing support structure is provided between the outer wall of the barrel 1 and the end cap 3.

[0030] See Figure 5 , Figure 6 , Figure 7 The aforementioned anti-fall-off limiting mechanism includes an upper ring 61 and a lower ring 62. The upper ring 61 is disposed on the outer periphery of the end cap 3, and the lower ring 62 is disposed on the outer periphery of the top of the barrel body 1. A plurality of upper blocks 63 are evenly arranged on the outer periphery of the upper ring 61 along the circumferential direction, and a plurality of lower blocks 64 are evenly arranged on the outer periphery of the lower ring 62 along the circumferential direction. The number of upper blocks 63 and lower blocks 64 is the same. The lower blocks 64 are disposed below the upper blocks 63. A threaded hole 65 is provided in the middle of the upper block 63, and a through hole 66 is provided in the middle of the lower block 64. The threaded hole 65 and the through hole 66 are coaxially arranged. The lower end is recessed upward to form a positioning groove 67. The lower block 64 is also provided with an exit groove 68. One end of the exit groove 68 is connected to the outside of the side of the lower block 64, and the other end of the exit groove 68 is connected to the side of the through hole 66 and the positioning groove 67. A limit screw 7 is provided in the threaded hole 65 and the through hole 66. The shank of the limit screw 7 is provided with an external thread, which is matched with the threaded hole 65. The head of the limit screw 7 is set in the positioning groove 67. The other end of the limit screw 7 is provided with a limit block 71. The width of the exit groove 68 is greater than or equal to the outer diameter of the limit screw 7.

[0031] Furthermore, the support structure includes a first positioning piece 81, a second positioning piece 82, a third positioning piece 83, and an L-shaped limiting rod 8. The first positioning piece 81 is disposed on the side of the end cap 3, the second positioning piece 82 and the third positioning piece 83 are respectively disposed on the outer wall of the barrel 1, and the third positioning piece 83 is disposed below the second positioning piece 82. The first positioning piece 81 and the second positioning piece 82 are respectively provided with limiting holes, and the third positioning piece 83 is provided with a limiting groove. The limiting groove has an opening in the direction of the outer side of the barrel 1. The long rod section of the limiting rod 8 passes through the two limiting holes along the axial direction, and the short rod section of the limiting rod 8 is disposed in the limiting groove.

[0032] Specifically, the two ends of the long rod section of the limiting rod 8 pass through the limiting hole, thereby limiting the circumferential direction of the limiting rod 8 and preventing it from falling off in the circumferential direction. The short rod section of the limiting rod 8 is embedded in the limiting slot, thereby limiting the axial direction of the limiting rod 8 and preventing it from falling off in the axial direction.

[0033] Example 2

[0034] See Figure 3 The difference between this embodiment and embodiment 1 is that in embodiment 1, the installation is achieved between the second mounting hole 42 and the wall 20, while in this embodiment, the installation is achieved between the first mounting hole 41 and the wall 20.

[0035] In Example 1, the tank 1 is in a vertical position, which is the conventional installation position of the water filter. In this example, the tank 1 is in a horizontal position.

[0036] When water is introduced into the barrel 1, there is a risk of leakage due to the vibration of the barrel 1 causing the sealing ring to deflect and be squeezed, resulting in uneven sealing. This risk is exacerbated, especially when the barrel 1 is in a horizontal position, as the weight deflection at the far end of the barrel 1 will further increase this risk. The limiting rod 8 passes through the first positioning piece 81 and the second positioning piece 82 on the barrel 1 and the end cap 3, providing auxiliary support for the barrel 1 while also limiting its movement to prevent the aforementioned deflection and leakage risk. In this embodiment, the limiting rod 8 is equivalent to a limiting pin.

[0037] Example 3

[0038] See Figure 8 , Figure 9 The difference between this embodiment and embodiment 1 is that both ends of the limiting rod 8 are hexagonal.

[0039] In this embodiment, the limiting rod 8 can be used as an internal hex wrench to directly adjust each fastening screw of the water filter, making it convenient to operate directly during daily inspections and maintenance, while preventing staff from forgetting or bringing the wrong tools.

[0040] Example 4

[0041] See Figure 10 This embodiment describes a connection method for the inlet and outlet ports of a water filter, with the remaining ports sealed with plugs.

[0042] Example 5

[0043] See Figure 11 This embodiment shows another way to connect the inlet and outlet ports of the water filter, while the other ports are sealed with plugs.

[0044] Example 6

[0045] See Figure 12 This embodiment shows another way to connect the inlet and outlet ports of the water filter, while the other ports are sealed with plugs.

[0046] In Example 4, water pipes 30 are connected to end caps 3 from the axial direction and side of the barrel 1, respectively; in Example 5, water pipes 30 are all connected to end caps 3 from the axial direction of the barrel 1; in Example 6, water pipes 30 are all connected to end caps 3 from the side of the barrel 1. Examples 4-6 demonstrate that the field piping of this device can have various layouts.

[0047] Work process:

[0048] During installation, connect the mounting bracket 4 to the end cap 3 (e.g.) Figure 1 As shown, the mounting bracket 4 has a mounting through hole, and the end cap 3 has a corresponding mounting screw hole. After the screw passes through the mounting through hole, it can be tightened into the mounting screw hole. The filter element 5 is connected to the end cap 3, and then the mounting bracket 4 is installed on the wall. Finally, hold the handle 2 and put the barrel 1 on the outside of the filter element 5. Rotate the barrel 1 by the handle 2 to rotate the lower block 64 to the lower block 63. At this time, the rod of the limit screw 7 slides into the lower block 64 through the exit slot 68. Finally, tighten the limit screw 7 upward so that the head of the limit screw 7 is embedded in the positioning slot 67.

[0049] In the horizontal installation state, the limiting rod 8 needs to be installed last. The long end of the limiting rod 8 is passed through the limiting holes of the second positioning piece 82 and the first positioning piece 81 in sequence, and then the short end is embedded into the limiting slot of the third positioning piece.

[0050] During disassembly, first loosen the limiting screw 7. The head of the limiting screw 7 will disengage from the positioning groove 67. The limiting block 7 of the limiting screw 7 will abut against the end face of the upper block 63. The limiting screw 7 will not be able to come out of the upper block 63. Then, hold the handle 2 and rotate the barrel 1 to disengage the limiting screw 7 from the lower block 64. The barrel 1 can then be pulled out, and the filter element 5 can be replaced.
