Description

Technical Field

[0001] The invention relates to the technical field of drinking water filter elements, and in particular to a bypass valve filter element assembly capable of adjusting a water mixing ratio. Background Art

[0002] Drinking water filter cartridges are the core filtering components of water purification equipment. They are composed of porous materials or functional media, including ceramic filter cartridges, hollow fiber ultrafiltration membranes, activated carbon, ion exchange resins, etc. They remove impurities and harmful substances (such as heavy metals, bacteria, residual chlorine, etc.) in tap water through physical interception, chemical adsorption, ion exchange, or biodegradation, thereby improving the safety and taste of water quality and meeting the standard for direct drinking. For example, the utility model with authorization announcement number CN204224368U discloses a filter cartridge for drinking water equipment. The filter cartridge body includes a cylinder and a cylinder cover provided at both ends of the cylinder; an activated carbon layer disposed within the filter cartridge body; and a magnesium ion layer disposed within the filter cartridge body and located at the downstream end of the activated carbon layer, forming a composite filter layer of the filter cartridge of the drinking water equipment with the activated carbon layer. The filter element of this drinking water equipment is equipped with a composite filter layer of activated carbon layer and magnesium ion layer in the filter element body, so as to directly adsorb, filter, deodorize, eliminate taste, energize, alkalize and reduce the water quality passing through the filter element body, thereby providing clean water that is beneficial to human health.

[0003] The key difference between hard and soft water lies in the calcium and magnesium ion content. Hard water, with higher concentrations of calcium and magnesium ions, typically has a total hardness above 120 ppm. Soft water, with lower concentrations of calcium and magnesium ions, typically has a total hardness below 60 ppm.

[0004] Take brewing tea and coffee as an example. Using soft water enhances purity and aroma, but also reduces extraction, resulting in a flat flavor. Using hard water enhances concentration and body, but can also lead to bitterness and off-flavors, disrupting the flavor balance. Therefore, choosing water of varying hardness can improve and adjust the flavor and mouthfeel of tea or coffee, satisfying the needs and personal preferences of different users for high-quality beverages.

[0005] Existing drinking water filters, such as ion exchange resin filters and reverse osmosis (RO) filters, can remove or significantly reduce calcium and magnesium ions in drinking water to produce soft water. However, these filters do not allow users to freely adjust the hardness of the water to produce drinking water with varying hardnesses. Furthermore, they do not allow users to adjust the hardness of drinking water after a certain period of use, as the filter's ability to process calcium and magnesium ions decreases.

[0034] Reference Figures 1-10 A bypass valve filter element assembly that can adjust the water mixing ratio includes a filter element body 1 and a bypass valve body 2 fixedly connected to the filter element body 1. The two can adopt a threaded connection structure or a clamping block and clamping groove connection structure. The connection and disassembly are convenient, and the filter element body 1 is easy to replace; a water purifier is generally composed of multiple stages of filter elements in series, such as activated carbon filter elements, ceramic filter elements, composite filter elements (activated carbon + PP cotton), etc., which filter tap water to obtain drinking water.

[0035] The bypass valve filter core assembly is generally arranged at the last stage of the water purifier. Tap water is filtered by the filter core at the front end and has reached the drinking water standard. However, the drinking water still contains a large amount of calcium and magnesium ions. The filter core body 1 of the application can filter the calcium and magnesium ions in the drinking water to obtain secondary filtered water. The bypass valve body 2 can freely adjust the mixing ratio of the drinking water and the secondary filtered water, so that the user can select water with different hardness. In addition, the content of calcium and magnesium ions can be obtained through a water quality detector, which can be used to brew tea or coffee with different flavors and tastes.

[0036] The bypass valve body 2 includes a bypass valve inlet pipe 3 and a bypass valve outlet pipe 4 arranged side by side, and the two are arranged side by side on the left and right, and are roughly in the same horizontal plane. A water baffle 5 is provided between the bypass valve inlet pipe 3 and the bypass valve outlet pipe 4, which is used to block the application water in the bypass valve inlet pipe 3 from flowing directly to the bypass valve outlet pipe 4; a hollow valve core mounting tube 6 is provided on the upper wall of one end of the bypass valve inlet pipe 3 (close to the end of the bypass valve outlet pipe 4), and also includes a plurality of first water mixing holes 7, which pass through one side pipe wall of the valve core mounting tube 6 and the water baffle 5 to form a through hole; a rotatable water volume regulating valve core 8 is installed in the valve core mounting tube 6, and the valve core mounting tube 6 is roughly perpendicular to the bypass valve inlet pipe 3, and extends to the middle of the bypass valve inlet pipe 3, and the water volume The lower end surface of the regulating valve core 8 and the lower end surface of the valve core mounting tube 6 are roughly located at the same horizontal plane; the water volume regulating valve core 8 includes a valve core rotating handle 9 and a valve core tube 91, which is a circular tube with an open end. The valve core rotating handle 9 is used to realize forward or reverse rotation; a plurality of second water mixing holes 10 corresponding to the positions and numbers of the plurality of first water mixing holes 7 are opened on the tube wall of the valve core tube 91, and the first water mixing holes 7 and the second water mixing holes 10 can be two, three or four of equal number; the lower end of the valve core tube 91 is connected to the bypass valve water inlet pipe 3, and the water volume regulating valve core 8 is rotated to control the conduction quantity of the first water mixing hole 7 and the second water mixing hole 10, so that part of the drinking water in the bypass valve water inlet pipe 3 directly enters the bypass valve through the first water mixing hole 7 and the second water mixing hole 10. The bypass valve outlet pipe 4 is connected to the bypass valve, thereby adjusting the mixing ratio of drinking water and re-filtered water; for example, all the first mixing holes 7 and all the second mixing holes 10 can be connected, or partially connected, so as to control the flow rate of drinking water flowing directly from the bypass valve inlet pipe 3 to the bypass valve outlet pipe 4; or none of them can be connected to prevent drinking water from flowing directly from the bypass valve inlet pipe 3 to the bypass valve outlet pipe 4; a bypass valve downpipe 11 (close to one end of the bypass valve outlet pipe 4) is provided on the lower wall of one end of the bypass valve inlet pipe 3, which is arranged side by side with the valve core mounting pipe 6, and the bypass valve downpipe 11 is connected to the bypass valve inlet pipe 3, and drinking water can enter the filter element body 1 through the bypass valve inlet pipe 3 and the bypass valve downpipe 11 to be re-filtered Filter to obtain re-filtered water, which finally flows into the bypass valve outlet pipe 4; some drinking water can also enter the bypass valve outlet pipe 4 through the bypass valve inlet pipe 3, the first mixing hole 7, and the second mixing hole 10. The two types of water are mixed in the bypass valve outlet pipe 4 and finally output to the user; it also includes a bypass valve connecting seat 12 for mounting the filter element body 1; a bypass valve outlet channel 13 is formed between the bypass valve connecting seat 12 and the bypass valve downpipe 11, so that the re-filtered water can flow into the bypass valve outlet pipe 4; the filter element body 1 includes a filter element connecting seat 14, a drinking water inlet connector 15 sleeved in the filter element connecting seat 14, and a second soft water outlet channel 16 formed between the filter element connecting seat 14 and the drinking water inlet connector 15;The filter element connection seat 14 is connected to the bypass valve connection seat 12. The upper end of the drinking water inlet connector 15 is fastened to the bypass valve downpipe 11. The second soft water outlet channel 16 is connected to the bypass valve outlet channel 13, and the bypass valve outlet channel 13 is connected to the bypass valve outlet pipe 4.

[0037] When in use, the filter element body 1 is fixed to the lower end of the bypass valve body 2, and the bypass valve water inlet pipe 3 is connected to the water outlet end of the upper filter element through a hose, so that drinking water enters the bypass valve water inlet pipe 3. At this time, the drinking water can flow in one or two ways.

[0038] The first route: The drinking water in the bypass valve inlet pipe 3 can enter the filter element body 1 through the bypass valve downpipe 11 for re-filtration, which is used to filter calcium and magnesium ions to obtain re-filtered water (i.e. soft water), and the re-filtered water finally flows into the bypass valve outlet pipe 4.

[0039] Second route: Drinking water in the bypass valve water inlet pipe 3, part of which can simultaneously enter the bypass valve water outlet pipe 4 through the first water mixing hole 7 and the second water mixing hole 10. The two types of water are mixed in the bypass valve water outlet pipe 4 and finally output to the user. By controlling the rotation of the water volume regulating valve core 8, the number of first water mixing holes 7 and second water mixing holes 10 that are open can be controlled, so that part of the drinking water in the bypass valve water inlet pipe 3 can directly enter the bypass valve water outlet pipe 4 through the first water mixing holes 7 and the second water mixing holes 10, thereby adjusting the mixing ratio of drinking water and re-filtered water. For example, all first water mixing holes 7 and all second water mixing holes 10 can be open, or they can be partially open, thereby controlling the flow rate of drinking water directly flowing from the bypass valve water inlet pipe 3 into the bypass valve water outlet pipe 4. Alternatively, all of the first water mixing holes 7 and all of the second water mixing holes 10 can be closed, preventing drinking water from directly flowing from the bypass valve water inlet pipe 3 into the bypass valve water outlet pipe 4.

[0040] When the filter element body 1 is used for the first time, its ability to filter calcium and magnesium ions is the strongest. Therefore, the first water mixing hole 7 and the second water mixing hole 10 can be fully connected. At this time, the drinking water directly flowing into the bypass valve outlet pipe 4 is the largest.

[0041] After the filter element 1 has been used for a certain period of time, its ability to filter calcium and magnesium ions becomes weaker, and the number of connections between the first water mixing hole 7 and the second water mixing hole 10 can be gradually reduced, thereby reducing the amount of drinking water that directly flows into the bypass valve outlet pipe 4;

[0042] When the filter element body 1 has been used for a longer time, its ability to filter calcium and magnesium ions becomes weaker. The above-mentioned water mixing holes can be completely closed so that drinking water cannot directly enter the bypass valve outlet pipe 4, but must be filtered through the filter element body 1.

[0043] Users can also use a water quality tester to obtain the content of calcium and magnesium ions and the hardness parameters of the water, thereby controlling the number of conduction holes mentioned above; the bypass valve body 2 can freely adjust the mixing ratio of drinking water and re-filtered water, allowing users to choose water of different hardness and hardness for brewing tea or coffee with different flavors and tastes.

[0044] In some embodiments, the filter element body 1 also includes a bottle body 17, which is roughly a hollow cylinder. A hollow tube 18 is installed in the bottle body 17, and an upper filter disc frame 19 and a lower filter disc frame 20 are installed at both ends of the hollow tube 18, which can be used to limit the range of movement of the filter material 21 and to install the filter screen; the bottle body 17 between the upper filter disc frame 19 and the lower filter disc frame 20 is filled with filter material 21, which can filter calcium and magnesium ions in the water, and at least one filter screen 22 is installed on the upper filter disc frame 19 and the lower filter disc frame 20, preferably multiple layers, which can be used to block the filter material 21 and further improve the water quality; a water holding cavity 23 is formed between the lower filter disc frame 20 and the inner bottom wall of the bottle body 17, and the hollow tube 18 is connected to the water holding cavity 23, so that the contact area between drinking water and the filter material 21 is increased, thereby optimizing the filtration efficiency and effect. ; The upper end of the upper filter screen disc frame 19 is equipped with an upper end cover 24, which includes an end cover housing 25 and a drinking water inlet connector 15 axially arranged at the upper end of the end cover housing 25. The upper end of the hollow tube 18 axially passes through the upper filter screen disc frame 19 and is plugged into the lower end of the drinking water inlet connector 15; the upper end of the upper end cover 24 is equipped with a filter element connecting seat 14, which includes a filter element connecting seat outer cover 26 and a filter element connecting seat tube 27 axially arranged at the upper end of the filter element connecting seat outer cover 26. The drinking water inlet connector 15 is sleeved in the filter element connecting seat tube 27, and the filter element connecting seat 14 is fastened to the top opening of the bottle body 17 to prevent water from overflowing. A first soft water outlet channel 28 is formed between the end surfaces of the upper filter screen disc frame 19 and the upper end cover 24, as well as between the end surfaces of the upper end cover 24 and the filter element connecting seat 14.

[0045] During use, drinking water enters the water holding chamber 23 through the bypass valve inlet pipe 3, the bypass valve downpipe 11, the drinking water inlet connector 15, and the hollow tube 18, and is filtered by the filter material 21 to obtain filtered water again. The water then flows from the first soft water outlet channel 28 between the upper filter screen rack 19 and the upper end cover 24, flows to the first soft water outlet channel 28 between the upper end cover 24 and the filter element connecting seat 14, and then flows to the second soft water outlet channel 16 formed between the filter element connecting seat 14 and the drinking water inlet connector 15, and then flows to the bypass valve outlet channel 13, and finally flows into the bypass valve outlet pipe 4.

[0046] In some embodiments, the upper filter disc frame 19 and the lower filter disc frame 20 both include a disc 29, a disc sleeve pipe 30 axially arranged in the middle of one end surface of the disc 29, an end cover sleeve pipe 31 axially arranged in the end cover housing 25, the lower end of the hollow tube 18 is plugged and fixed in the disc sleeve pipe 30 of the lower filter disc frame 20, and the upper end of the hollow tube 18 passes through the disc sleeve pipe 30 and the end cover sleeve pipe 31 of the upper filter disc frame 19 in sequence, and then is plugged and fixed in the drinking water inlet joint 15. The above structure can achieve fast connection between the various components. Quick assembly and disassembly facilitates the production of various components, saves costs and improves production efficiency. Seals can be installed at the joints between the components to further improve the waterproof performance. The outer wall of the disc 29 is in close contact with the inner wall of the bottle body 17 to prevent the filter material 21 from overflowing. A plurality of reinforcing plates 32 are evenly distributed on one end surface of the disc 29. The reinforcing plates 32 are roughly triangular and are used to improve the compressive strength. Spaces for water to pass through are formed between the plurality of reinforcing plates 32. A plurality of through holes 290 are evenly opened on the disc 29. The mesh diameter of the filter screen 22 is smaller than the diameter of the through holes.

[0047] In some embodiments, the outer ring of the end cap shell 25 is pressed tightly against the multiple reinforcing plates 32 of the upper filter disc frame 19; an annular gap is formed between the outer wall of the end cap shell 25 and the inner wall of the bottle body 17, through which re-filtered water can pass.

[0048] In some embodiments, the outer wall of the filter element connection seat outer cover 26 is in close contact with the inner wall of the bottle body 17, and a plurality of reinforcing blocks 33 are evenly distributed inside the filter element connection seat outer cover 26. The reinforcing blocks 33 are roughly triangular and are used to improve the compressive strength. A space for water to pass through is formed between the plurality of reinforcing blocks 33; the plurality of reinforcing blocks 33 are pressed tightly against the upper end face of the end cover shell 25, and an annular gap is also formed between the inner wall of the filter element connection seat outer cover 26 and the outer wall of the end cover shell 25, which can allow filtered water to pass through again.

[0049] In some embodiments, at least one sealing ring 34 is provided on the outer wall of the water regulating valve core 8, the filter element connecting seat tube 27 and the drinking water inlet joint 15, preferably two or more, to improve the anti-leakage performance.

[0050] In some embodiments, a knob 35 is mounted on the valve core rotating handle 9. Multiple markings 36 are arranged side by side on the sidewalls of the knob 35 to indicate the number of connections between the first mixing hole 7 and the second mixing hole 10. Specifically, the markings 36 are multiple numbers; for example, when there are three first mixing holes 7 and three second mixing holes 10, the markings are 0, 1, 2, and 3. 0 represents zero connections between the first mixing hole 7 and the second mixing hole 10, 1 represents one connection, and so on. This facilitates intuitive and convenient observation.

[0051] In some embodiments, the filter material 21 is preferably cation exchange resin particles, and can also be nano-aluminum silicate particles. The cation exchange resin particles have the following advantages: high efficiency softening, large treatment capacity, renewable cycle, long-term economy, mature technology, and strong adaptability. The nano-aluminum silicate particles have the following advantages: direct replacement of the filter core after adsorption saturation, without the need for salt or acid regeneration, avoiding waste water discharge, and partial modified models (such as silver-loaded models) have antibacterial functions, can be combined with activated carbon and ultrafiltration membranes, and can simultaneously remove organic matter and particulate matter.
