[0024] Combined with the attached Figure 1 - attached Figure 5 , a multifunctional filtering device, comprising a filter bottle 1, a filter head arranged above the filter bottle 1, and a filter element assembly arranged inside the filter bottle 1. The upper part of the filter bottle 1 is clamped with an upper end cover 2, and the upper end cover 2 is provided with a bottle mouth 3;

[0025] The filter head includes a mounting seat 4 clamped on the upper end cover 2. The mounting seat 4 is provided with a water guide seat 5. The two ends of the water guide seat 5 are respectively provided with a water inlet pipe 6 and a water outlet pipe 7. The lower end of the water guide seat 5 is provided with a drain pipe 8, and the lower end of the drain pipe 8 is sleeved on the upper end of the bottle mouth 3 and communicated with the bottle mouth 3. The middle part of the drain pipe 8 is installed with a water supply pipe 10 through a leakage mounting plate 9;

[0026] The filter element assembly includes a core body 11, a filter element upper cover 12 and a filter element lower cover 13 which are respectively connected above and below the core body 11. The lower end of the upper water pipe 10 extends into the bottle mouth 3 and the lower end of the upper water pipe 10 is sleeved on the water outlet at the upper end of the filter element upper cover 12;

[0027] The inside of the water guide seat 5 is provided with an installation cavity and a valve block is rotatably arranged in the installation cavity. The valve block includes a valve block top cover 14, a central pipe 15 and an outer pipe 16. The central pipe 15 and the outer pipe 16 are both installed below the valve block top cover 14 and the central pipe 15 is located in the middle of the outer pipe 16. The lower end of the central pipe 15 is rotatably arranged on the upper water pipe 10 and the central pipe 15 is communicated with the upper water pipe 10. The outer pipe 16 is provided with a water inlet 17 corresponding to and communicated with the water inlet pipe 6. One side of the outer pipe 16 opposite to the water inlet 17 is provided with a water guide pipe 18 communicated with the central pipe 15 and the water guide pipe 18 is corresponding to and communicated with the water outlet pipe 7. A straight-through pipe 19 is also penetrated and connected in the middle of the central pipe 15 and the outer pipe 16, and when the valve block rotates, both ends of the straight-through pipe 19 can be directly communicated with the water inlet pipe 6 and the water outlet pipe 7.

[0028] In one embodiment, six seal ring installation grooves 20 are circumferentially arranged on the outer pipe 16, and a seal ring 21 is arranged in each seal ring installation groove 20. Two of the seal ring installation grooves 20 are respectively installed at the outer ring positions of the ports of the water inlet 17 and the water guide pipe 18, and the other two seal ring installation grooves 20 are respectively installed at the outer ring positions of the two ends of the straight-through pipe 19. The seal rings 21 in the last two seal ring installation grooves 20 are used to block the outlet of the water inlet pipe 6 and the inlet of the water outlet pipe 7. In this embodiment, six seal ring installation grooves 20 are designed on the outer pipe 16, and a seal ring 21 is installed in each groove. These seal rings 21 not only enhance the sealing performance between the valve block and the water guide seat 5, prevent water leakage, but also ensure the sealing effect in different working gears (such as normal filtration, straight-through, closed). In particular, the seal rings 21 located at the outer ring positions of the ports of the water inlet 17, the water guide pipe 18 and the straight-through pipe 19 ensure the accurate control of water flow at these key positions. In addition, the seal rings 21 used to block the outlet of the water inlet pipe 6 and the inlet of the water outlet pipe 7 provide additional safety protection in the closed gear.

[0029] In one embodiment, the mounting seat 4 is provided with a cover 22 covering the water guide seat 5, and the cover 22 is fixedly connected with the upper part of the water guide seat 5 through fixing screws. The design of the cover 22 not only enhances the structural strength of the whole filter head, but also protects the internal valve block and connecting components from the influence of the external environment.

[0030] In one embodiment, a rotating shaft 23 is provided above the valve block top cover 14. Through holes for the rotating shaft 23 to pass through are provided on both the water guide seat 5 and the cover 22, and a knob 24 located above the cover 22 is provided on the rotating shaft 23. In one embodiment, an exhaust cavity 25 is provided inside the rotating shaft 23. An installation port 26 is provided at the upper end of the rotating shaft 23, and the installation port 26 is communicated with the exhaust cavity 25 through a pressure relief hole 27. A pressure relief button 29 is connected inside the installation port 26 through a spring 28, and the pressure relief button 29 can slide up and down inside the installation port 26. A mounting screw 30 is provided at the center of the bottom of the pressure relief button 29. The bottom of the mounting screw 30 passes through the pressure relief hole 27 and extends into the exhaust cavity 25. A rubber gasket 31 is provided on the mounting screw 30 below the pressure relief hole 27, and the rubber gasket 31 can block the pressure relief hole 27. This embodiment details the rotating shaft 23 above the valve block top cover 14 and its supporting components. The rotating shaft 23 not only serves as the axis of rotation of the valve block but also integrates an exhaust function. By rotating the knob 24, the user can easily adjust the position of the valve block to achieve the switching of different working gears. In addition, the exhaust cavity 25, the pressure relief hole 27, and the associated pressure relief button 29 and rubber gasket 31 inside the rotating shaft 23 demonstrate their unique convenience during the filter element replacement. Since the air pressure in the water circuit may change during the filter element replacement process, traditional equipment often lacks direct and effective pressure release means, increasing the operation difficulty and safety hazards. The pressing pressure relief mechanism in this embodiment allows the user to quickly release the excessive pressure in the water circuit by simply pressing the pressure relief button 29 before or during the filter element replacement, thus greatly simplifying the filter element replacement process and reducing the operation difficulty.

[0031] In one embodiment, an L-shaped mounting plate 32 is installed on the water guide seat 5 by screws. This embodiment emphasizes the importance of the L-shaped mounting plate 32 during the installation of the filter element. The L-shaped mounting plate not only provides a stable mounting foundation but also ensures that the filter element can be accurately and firmly fixed in the designated position. After fixing the L-shaped mounting plate in place by screws, the inlet pipe 6 and the outlet pipe 7 can be conveniently connected to the filter element through the internal thread structure. This mounting method is both simple and reliable, providing convenience for subsequent filtering operations and filter element replacement.

[0032] Working principle: The filter element of this application is exquisitely designed and integrates multiple functions such as filtration, convenient filter element replacement, and safety pressure relief. First, the filter element is stably installed in the designated position through the L-shaped mounting plate 32, and the inlet pipe 6 and the outlet pipe 7 are connected to the corresponding water circuit system. When the water pump is started, the water to be filtered first enters the inlet pipe 6, and then enters the flowing water gap formed by the central pipe 15 and the outer pipe 16 through the water inlet 17. Inside this gap, the water flows through the leakage holes on the leakage mounting plate 9 and enters the filter bottle 1.

[0033] Inside the filter bottle 1, water flows through the core body 11 of the filter element assembly for filtration. After removing impurities, the clear water enters the upper water pipe 10 through the water outlet of the filter element upper cover 12 and further flows into the central pipe 15. Subsequently, the filtered water flows into the outlet pipe 7 through the water guide pipe 18 connected to one side of the central pipe 15 and finally flows out, completing the entire filtration process.

[0034] This filter element is specially designed with three working gears to meet different needs. The first gear is the normal filtration mode as described above. When the filter element assembly needs to be replaced, by rotating the knob 24 to drive the overall rotation of the valve block, both ends of the straight-through pipe 19 are directly connected to the water inlet pipe 6 and the outlet pipe 7, forming a non-filtering straight-through mode. At this time, water can directly enter the outlet pipe 7 from the water inlet pipe 6 through the straight-through pipe 19, facilitating the removal of the filter bottle 1 for filter element replacement without stopping the water supply.

[0035] If it is necessary to further close the water circuit, rotate the knob 24 again so that neither the straight-through pipe 19 nor the water inlet 17 is connected to the water inlet pipe 6. At the same time, use the sealing ring 21 at a specific position to block the outlet of the water inlet pipe 6 and the inlet of the outlet pipe 7 to achieve a complete closure of the water circuit.

[0036] In addition, to address the air pressure problem in the water circuit, this design also integrates a safety pressure relief mechanism. By pressing the pressure relief button 29, the installation screw 30 and the rubber gasket 31 thereon are driven to move downward, thereby opening the pressure relief hole 27 originally blocked by the rubber gasket 31. At this time, the gas in the water circuit can be smoothly discharged along the exhaust cavity 25, the pressure relief hole 27 and the installation port 26. This design shows its unique convenience during filter element replacement. Since the air pressure in the water circuit may change during the filter element replacement process, traditional devices often lack direct and effective pressure release means, increasing the operation difficulty and safety hazards. The pressing pressure relief mechanism in this embodiment allows users to quickly release the excessive pressure in the water circuit by simply pressing the pressure relief button 29 before or during filter element replacement, thus greatly simplifying the filter element replacement process and reducing the operation difficulty.

[0037] The above describes the present utility model and its implementation manners. This description is not restrictive, and what is shown in the drawings is only one of the implementation manners of the present utility model. The actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative efforts without departing from the creative concept of the present utility model, they shall fall within the protection scope of the present utility model.
