Description

Technical Field

[0001] This utility model relates to a filter with an adjustable water inlet ratio. Background Technology

[0002] In the water treatment field, filters, as crucial devices for improving water quality, are widely used in residential, commercial, and industrial settings. However, existing adjustable proportioning filters suffer from significant technical shortcomings in practical applications. Traditional filters typically use a main water path where the water flows through a filter cartridge for softening or mineralization, while branch paths bypass the cartridge, with the two streams mixing at the head before exiting. This design can easily lead to unfiltered water from the branch paths contaminating the main water path when the influent water quality is poor, significantly reducing the purity of the mixed water. Furthermore, due to significant regional variations in water quality, with some areas having low or high water hardness, using high-hardness water can cause scaling in equipment, while excessively low hardness can affect the flavor of brewed beverages such as coffee and milk tea. Therefore, existing technologies struggle to meet the personalized water quality adjustment needs of users in different regions.

[0003] Existing filters also have certain limitations in their structural design. For example, traditional filters typically only offer a single filtration mode and lack flexible ratio adjustment functions, making it impossible to adjust the ratio of filtered water to bypass water according to actual needs. Furthermore, while some filters do possess some adjustment capabilities, their water flow-to-filter media contact efficiency is low, resulting in unsatisfactory purification effects. Summary of the Invention

[0004] This utility model discloses a filter with an adjustable water inlet ratio, which aims to solve the problems mentioned above.

[0005] The present invention adopts the following solution:

[0006] An adjustable water inlet ratio filter includes a body and a filter bottle that are connected to each other. The body is provided with an inlet channel and an outlet channel, and the outlet pipe of the filter bottle is connected to the outlet channel. The filter bottle is provided with an outer ring inlet and an inner ring inlet. The filter bottle is provided with a first filtration zone and a second filtration zone. The outer ring inlet is connected to the first filtration zone, and the inner ring inlet is connected to the second filtration zone. The outlets of both the first and second filtration zones are connected to the outlet pipe. The body is provided with a valve core. The inlet of the valve core is connected to the inlet channel. The first outlet of the valve core is configured to be connected to the outer ring inlet, and the second inlet of the valve core is configured to be connected to the inner ring inlet. The valve core is configured to allow water to flow out from the first outlet alone, or from both the first and second outlets simultaneously.

[0007] In this embodiment of the utility model, the valve core further includes a third water outlet, which is configured to be connected to the water outlet channel. The valve core is configured to have three water outlet modes, including: water outlet alone at the first water outlet, water outlet alone at the third water outlet, and water outlet together at the first water outlet and the second water outlet.

[0008] In this embodiment of the present invention, the first filtration zone inside the filter bottle is located below the second filtration zone, the first filtration zone is filled with filter media, and the second filtration zone is provided with filter cloth.

[0009] In this embodiment of the present invention, the water inlet of the first filtration zone is located at the bottom of the inner cavity of the filter bottle. The water flow from the outer ring inlet flows from top to bottom into the bottom of the filter bottle and then into the first filtration zone. The water flow in the first filtration zone flows from bottom to top through the filter material and then flows out from the outlet pipe.

[0010] In this embodiment of the present invention, the filter bottle is further provided with a mixing zone, which is located between the first filtration zone and the second filtration zone. Water from the first filtration zone flows into the mixing zone from bottom to top, and water from the second filtration zone flows into the mixing zone from top to bottom. The water from the mixing zone can flow to the outlet channel through the outlet pipe.

[0011] In this embodiment of the present invention, a PP layer is disposed above the first filtration zone, and the above-mentioned mixing zone is formed between the PP layer and the second filtration zone.

[0012] In this embodiment of the invention, a filter cloth is disposed in the mixing zone.

[0013] In this embodiment of the present invention, an end cap is provided above the first filtration zone, and a water inlet chamber is provided inside the filter bottle located between the end cap and the second filtration zone. Spray holes are provided on the end cap, and water flowing into the water inlet chamber from the outer ring water inlet can be sprayed into the first filtration zone through the spray holes.

[0014] In this embodiment of the present invention, a central tube is provided in the first filtration zone. The upper end of the central tube can be connected to the water outlet pipe, and the lower end of the central tube is located below the first filtration zone. The water filtered by the filter material can flow from below the central tube to the water outlet pipe.

[0015] In this embodiment of the present invention, a water collection area is provided below the first filtration area, and a filter cloth is provided in the water collection area. The water that has been filtered by the filter material can flow through the water collection area to the lower inlet of the central pipe.

[0016] The technical solution of this utility model achieves its technical effect through the following means:

[0017] Firstly, based on the valve core's structural design, the valve core, with its independent first and second outlets, distributes the water flow from the outer and inner ring inlets to different filtration zones. The first outlet of the valve core is connected to the outer ring inlet, allowing water to enter the first filtration zone for fine filtration; the second outlet is connected to the inner ring inlet, allowing water to enter the second filtration zone for coarse filtration or functional treatment. Furthermore, through the valve core's adjustment function, three water output modes can be achieved: S1, first outlet-only water output mode, i.e., full filtration only through the first filtration zone; S2, third outlet-only water output mode, i.e., water is directly output without any filtration; S3, first and second outlets combined water output mode, i.e., water is mixed and filtered in different proportions using both the first and second filtration zones simultaneously. This design allows users to choose the appropriate filtration method according to their actual needs, improving the user experience.

[0018] Secondly, based on the multi-zone filtration design inside the filter bottle, the first and second filtration zones achieve efficient filtration through different water flow paths. The first filtration zone is located at the bottom of the filter bottle and is filled with filter media. Water can permeate upwards from below or spray downwards from above, ensuring full contact between the water and the filter media and improving filtration efficiency. The second filtration zone is located at the top of the filter bottle and is equipped with filter cloth. After entering from the inner ring inlet, the water directly undergoes coarse filtration through the filter cloth. In the spray method embodiment, the spray holes on the end cap evenly spray water onto the surface of the filter media, further enhancing the contact area between the water and the filter media and improving the purification effect. In addition, a central pipe and a water collection area are configured below the second filtration zone. The water filtered by the filter media flows through the water collection area to the lower inlet of the central pipe and finally merges into the outlet pipe. In the embodiment where water permeates from bottom to top, the mixing zone is located between the first filtration zone and the second filtration zone. Water from the first filtration zone flows into the mixing zone from bottom to top, while water from the second filtration zone flows into the mixing zone from top to bottom. After the two water flows are fully mixed in the mixing zone, they flow uniformly into the outlet channel through the outlet pipe. A filter cloth is installed in the mixing zone to further optimize the mixing effect and ensure the uniformity of the effluent water quality.

[0019] This utility model provides an adjustable water inlet ratio filter, which has the following beneficial effects: First, it precisely adjusts the water quality ratio. Through the adjustment function of the valve core, the water flow ratio between the outer and inner inlets can be precisely controlled, thereby adjusting the filtered water quality ratio. For example, in the mode where the first and second outlets are both outlets, by adjusting the flow ratio of the two, the effect of full filtration accounting for 60% of the total output water and coarse filtration accounting for 40% of the total output water can be achieved, meeting the needs of different regions and scenarios. Second, it improves filtration efficiency. The multi-zone filtration design inside the filter bottle and the optimization of the water flow path ensure sufficient contact between the water flow and the filter media, significantly improving filtration efficiency. The second filtration zone can permeate upwards from below or downwards from above, making the water flow evenly distributed on the surface of the filter media, improving the purification effect. Third, it maintains water purity. Through the body-diverting technology, the water flow from the outer inlet undergoes fine filtration through the filter media, while the water flow from the inner inlet only undergoes coarse filtration, avoiding contamination of the main water path by branch water flow and effectively maintaining the purity of the output water. Fourth, strong adaptability. The second filtration zone can be filled with softening resin or mineralized stone to improve water hardness issues that are too high or too low, meeting users' personalized needs. For example, in hard water areas, softening resin can be filled to reduce water hardness, while in low-hardness areas, mineralized stone can be filled to increase the mineral content of the water. Fifth, enhanced user experience. With three water output modes (full filtration, adjustable filtration ratio, and no filtration), users can choose the appropriate filtration method according to their actual needs, ultimately improving the user experience.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0031] Referring to the accompanying drawings, this utility model provides a filter with an adjustable water inlet ratio. The core structure of the filter includes a body 1 and a filter bottle 2, which are connected together to form a complete filtration device. The body 1 is equipped with an inlet channel 3 and an outlet channel 4 for guiding water flow into and out of the filter. The filter bottle 2 has a multi-zone filtration structure inside, and the valve core 10 on the body 1 enables precise control of the water flow path and ratio.

[0032] In this embodiment, the outer ring inlet 5 and the inner ring inlet 6 of the filter bottle 2 are connected to different filtration zones. The outer ring inlet 5 is connected to the first filtration zone 7, which is located at the bottom of the filter bottle 2 and is filled with filter media 14, mainly used for fine filtration of the water flow. The inner ring inlet 6 is connected to the second filtration zone 8, which is located at the top of the filter bottle 2 and is equipped with filter cloth 15, used for coarse filtration or functional treatment. The outlets of both the first filtration zone 7 and the second filtration zone 8 can be connected to the outlet pipe 21, and the filtered water flow is finally combined and flows out from the outlet channel 4. The filter media filled in the first filter media zone can be resin, mineral stone, etc.; while the second filtration zone performs coarse filtration and can be filter cloth.

[0033] After water enters the main body 1 through the inlet channel 3, it is distributed to different water flow paths by the valve core 10. The valve core 10 has an inlet 22 and multiple outlets, where the first outlet 11 is connected to the outer ring inlet 5, the second outlet 12 is connected to the inner ring inlet 6, and the third outlet 13 is directly connected to the outlet channel 4. The design of the valve core 10 enables the filter to achieve three water discharge modes: water discharge mode with the first outlet 11 alone, water discharge mode with the third outlet 13 alone, and water discharge mode with the first outlet 11 and the second outlet 12 together. By adjusting the valve core 10, the user can flexibly select the desired water discharge mode and filtration mode.

[0034] In the single-outlet mode of the first outlet 11, water flows only through the outer ring inlet 5 into the first filtration zone 7 for full filtration. In the first embodiment of the filter bottle of this utility model, the water flowing from the outer ring inlet 5 into the bottom of the filter bottle 2 from top to bottom, and then from bottom to top through the filter media 14 for fine filtration. This water flow path design prolongs the contact time between the water flow and the filter media 14, significantly improving the filtration efficiency. The water filtered by the filter media 14 flows from the outlet end of the first filtration zone 7 to the outlet pipe 21, and finally flows out from the outlet channel 4.

[0035] In the stand-alone water outlet mode of the third outlet 13, water flows directly from the inlet 3 to the outlet 4 without filtration. This mode is suitable for scenarios with low water quality requirements, such as flushing water or drainage needs during equipment maintenance. By adjusting the valve core 10, users can quickly switch to the unfiltered mode, avoiding unnecessary energy and resource waste.

[0036] In the mode where the first outlet 11 and the second outlet 12 both flow out, water simultaneously enters the first filtration zone 7 and the second filtration zone 8 through the outer ring inlet 5 and the inner ring inlet 6. In the first embodiment of this utility model filter bottle, after the water flows into the first filtration zone 7 through the outer ring inlet 5, it can undergo fine filtration along the aforementioned bottom-up path. The water flows directly into the second filtration zone 8, undergoes coarse filtration through the filter cloth 15, and then flows down into the mixing zone 9. The mixing zone 9 is located between the first filtration zone 7 and the second filtration zone 8. The water from the first filtration zone 7 flows into the mixing zone 9 from bottom to top, and the water from the second filtration zone 8 flows into the mixing zone 9 from top to bottom. After the two water flows are fully mixed in the mixing zone, they flow uniformly into the outlet channel 4 through the outlet pipe 21. The mixing zone 9 is equipped with a filter cloth 15 to further optimize the mixing effect and ensure the uniformity of the effluent water quality.

[0037] In the second embodiment of the filter bottle of this utility model, an end cap 17 is disposed above the first filtration zone 7, and spray holes 18 are arranged on the end cap 17. The direction of water flow into the first filtration zone is different from that in the first embodiment. The water flow entering the water inlet 23 from the outer ring water inlet 5 can be evenly sprayed onto the surface of the filter material in the first filtration zone 7 through the spray holes 18. The water flow is from top to bottom. This design allows the water flow to fully contact the filter material, significantly improving the purification effect. A central tube 19 is disposed in the first filtration zone 7. The upper end of the central tube 19 is connected to the water outlet pipe 21, and the lower end is located below the first filtration zone 7. A water collection area 20 is disposed below the first filtration zone 7. A filter cloth 15 is disposed in the water collection area 20. The water flow after being filtered by the filter material 14 can flow through the water collection area 20 (which can be filtered again) to the lower inlet of the central tube 19, and finally flow into the water outlet pipe 21. The filter cloth can also be made of PP cotton, filter screen, or other materials that can undergo coarse filtration.

[0038] In the first embodiment of this utility model filter bottle, the filter bottle 2 is further equipped with a PP layer 16, which can be made of sintered polypropylene. The PP layer 16 is located above the first filtration zone 7 and below the second filtration zone 8, forming a mixing zone 9. The design of the PP layer 16 not only supports the filter cloth located in the mixing zone, but also effectively blocks impurities from entering the mixing zone 9, ensuring the quality of the water flow in the mixing zone 9. The filter cloth 15 in the mixing zone 9 further optimizes the mixing effect, allowing the water flow in the first filtration zone 7 and the second filtration zone 8 to fully blend, resulting in a more uniform output water quality.

[0039] In practical applications, the filter of this invention can flexibly adjust the filtration ratio according to the needs of different regions and scenarios. For example, in hard water areas, softening resin can be filled in the first filtration zone 7 to reduce water hardness; in low-hardness areas, mineral stones can be filled in the first filtration zone 7 to increase the mineral content in the water. For example, by adjusting the valve core 10, users can achieve a total filtration rate of 60% and a coarse filtration rate of 40% of the total effluent, meeting personalized needs.

[0040] The adjustable valve core 10 of this filter provides users with great convenience during use. In household drinking water treatment scenarios, users can choose the full filtration mode to ensure the safety and purity of drinking water; in industrial water treatment scenarios, users can choose the adjustable filtration ratio mode to adjust the water quality according to process requirements; in equipment maintenance scenarios, users can choose the non-filtration mode to quickly complete drainage operations. This multi-functional design significantly enhances the user experience.

As previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments.
