Abstract
Description
Technical Field
[0001] This utility model relates to a water circuit board and a water purifier. Background Technology
[0002] As water purification equipment becomes increasingly common in homes, devices that only purify water are no longer sufficient to meet the needs of some users. Users want purified water that is safe and retains its minerals. Different groups have different requirements for the mineral content of water. For example, young children and the elderly need to supplement their bodies with more minerals, so they require water containing more minerals. Meanwhile, some young people, who are generally healthy and have high standards for the taste of water, prefer water with as few ions as possible to ensure a good taste. Traditional water purification equipment has a wastewater ratio solenoid valve in the wastewater passage, with a fixed orifice size that cannot be adjusted. This results in a relatively stable TDS (Total Dissolved Solids) level in the purified water, with minimal deviation, making it difficult to meet diverse needs. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a water circuit board and a water purifier.
[0004] The present invention solves the above-mentioned technical problems through the following technical solution:
[0005] A water circuit board includes a water circuit board body and a wastewater ratio adjustable valve. The water circuit board body has a wastewater passage inside, which is connected to the internal passage of the wastewater ratio adjustable valve. The water circuit board body has a valve seat with a first flow hole and a second flow hole. Both the first and second flow holes are located on the wastewater passage. The inner wall of the first flow hole has an inclined groove with an inner diameter that gradually decreases from the outside to the inside. The wastewater ratio adjustable valve includes a valve core, a sealing cover, and a driving mechanism. The valve core has an abutment portion corresponding to the first flow hole. The abutment portion can move towards or away from the first flow hole to change the flow rate of the first flow hole. The sealing cover is installed on the valve seat, and the valve core passes through and slides on the sealing cover. A channel is formed between the sealing cover and the valve seat, which connects the first flow hole and the second flow hole. The driving mechanism is used to drive the valve core to move.
[0006] In this solution, the water circuit board has a wastewater ratio adjustable valve installed in the internal wastewater passage. Since both the first and second flow holes are located in the wastewater passage, the first flow hole on the valve seat is connected to one end of the wastewater passage, and the second flow hole on the valve seat is connected to the other end of the wastewater passage. The wastewater passage is connected through the internal passage of the wastewater ratio adjustable valve. At the same time, since the inner wall of the first flow hole has an inclined groove with the inner diameter of the groove gradually decreasing from the outside to the inside, when the abutting part of the valve core moves towards the first flow hole, the flow rate of the first flow hole will decrease. When the abutting part of the valve core moves away from the first flow hole, the flow rate of the first flow hole will increase. This realizes the flow rate adjustment of the first flow hole, which in turn changes the flow rate of the wastewater passage, thus realizing the adjustment of the wastewater flow rate. This allows users to adjust the wastewater volume as needed, thereby obtaining purified water with different mineral contents.
[0007] For example, in areas with good water quality, the flow rate of the wastewater passage can be reduced by adjusting the wastewater ratio adjustable valve, thereby reducing wastewater volume. Conversely, in areas with relatively high ion content in the water, the flow rate of the wastewater passage can be increased by adjusting the wastewater ratio adjustable valve, thereby improving the membrane's retention rate and reducing the ion content in the purified water.
[0008] Preferably, the first flow hole includes a first section and a second section in sequence along the depth direction, the groove is located in the first section, and the abutment portion closes the first flow hole when it moves to the second section;
[0009] And / or, the edge of the first flow hole is further provided with a chamfer, the chamfer being used to guide the abutment portion into the first flow hole.
[0010] In this design, since the inner diameter of the groove gradually decreases from the outside to the inside, the abutting part adjusts the flow rate of the first flow hole when it moves within the first section. Because the second section lacks a groove, the abutting part closes the first flow hole when it moves to the second section.
[0011] Preferably, the water circuit board body has a recess, the valve seat is disposed at the bottom of the recess, the sealing cover is embedded in the recess, and the outer peripheral surface of the sealing cover abuts against the inner wall of the recess.
[0012] In this design, the valve seat is positioned at the bottom of the recess, and the inner wall of the recess limits the sealing cover, which facilitates the installation and fixing of the sealing cover and also facilitates the sealing connection between the sealing cover and the valve seat.
[0013] Preferably, the wastewater ratio adjustable valve further includes a sealing element, which is sleeved on the outside of the abutment portion, and the outer peripheral surface of the sealing element is used to abut against the inner wall of the first flow hole.
[0014] In this solution, when the abutting part moves to the second section, a sealing element is fitted on the outside of the abutting part to seal the gap between the abutting part and the first flow hole, thereby improving the sealing effect of the abutting part when closing the first flow hole.
[0015] Preferably, the wastewater ratio adjustable valve further includes a first sealing ring, which is sleeved on the valve core, and the outer peripheral surface of the first sealing ring abuts against the sealing cover.
[0016] In this solution, by setting a first sealing ring between the valve core and the sealing cover, the sealing effect between the valve core and the sealing cover is improved, preventing water from leaking out from the gap between the valve core and the sealing cover.
[0017] Preferably, the wastewater ratio adjustable valve further includes a second sealing ring, which is sleeved on the outer peripheral surface of the sealing cover, and the outer peripheral surface of the second sealing ring abuts against the inner wall of the recess.
[0018] In this design, the second sealing ring is fitted around the outer periphery of the sealing cover. The second sealing ring is used to seal the gap between the inner wall of the recess and the sealing cover, preventing water leakage from the gap between the outer periphery of the sealing cover and the inner wall of the recess, thereby improving the sealing effect.
[0019] Preferably, the wastewater ratio adjustable valve further includes a third sealing ring, which is disposed between the sealing cover and the valve seat, and is embedded in the valve seat or the sealing cover.
[0020] In this design, a third sealing ring is installed between the sealing cap and the valve seat. The third sealing ring is pressed against the valve seat by the sealing cap to prevent water from leaking out from the gap between the sealing cap and the valve seat, thereby improving the sealing effect.
[0021] Preferably, the wastewater ratio adjustable valve further includes a pressure cap, which is installed on the water circuit board body by fasteners. The pressure cap is sleeved on the valve core and embedded in the recess, and the lower edge of the pressure cap abuts against the upper edge of the sealing cap.
[0022] In this solution, the gland is installed on the water circuit board body by fasteners. The gland limits and fixes the sealing cover to the valve seat, which facilitates the installation and removal of the sealing cover and also improves the fixing effect of the sealing cover.
[0023] Preferably, the wastewater ratio adjustable valve further includes a threaded component, which is installed on the outside of the sealing cover. The valve core passes through and is threadedly connected to the threaded component. The drive mechanism is connected to the valve core and is used to drive the valve core to rotate.
[0024] In this design, the valve core is threadedly connected to a threaded component, which secures the valve core. Simultaneously, by rotating the valve core, it can move towards or away from the valve seat with the assistance of the threaded component, thereby adjusting the flow rate through the first flow orifice. The threaded component is a nut.
[0025] Preferably, the drive mechanism includes a motor, the output shaft of which is connected to the valve core, and the motor is used to drive the valve core to rotate.
[0026] In this solution, the motor can be electrically connected to the controller, which controls the rotation of the motor, facilitating automatic control and enabling the adjustment of the size of the wastewater passage.
[0027] In another alternative, the drive mechanism includes a knob mounted on the end of the valve core, which allows for manual adjustment of the wastewater passage size, making operation simple and convenient.
[0028] A water purifier comprising the water circuit board as described above.
[0029] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.
[0030] The positive and progressive effects of this utility model are as follows: The water circuit board has a wastewater ratio adjustable valve installed in the internal wastewater passage. Since both the first flow hole and the second flow hole are located in the wastewater passage, the first flow hole on the valve seat is connected to one end of the wastewater passage, and the second flow hole on the valve seat is connected to the other end of the wastewater passage. The wastewater passage is connected through the internal passage of the wastewater ratio adjustable valve. Since the inner wall of the first flow hole has an inclined groove with the inner diameter of the groove gradually decreasing from the outside to the inside, when the abutting part of the valve core moves towards the first flow hole, the flow rate of the first flow hole will decrease. When the abutting part of the valve core moves away from the first flow hole, the flow rate of the first flow hole will increase. This realizes the adjustment of the flow rate of the first flow hole, and correspondingly changes the flow rate of the wastewater passage, thus realizing the adjustment of the wastewater flow rate. This allows users to adjust the wastewater volume as needed, thereby obtaining purified water with different mineral contents. Attached Figure Description

[0060] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.
[0061] like Figures 1-7 As shown, this embodiment discloses a water circuit board, which includes a water circuit board body 1 and a wastewater ratio adjustable valve 2. The water circuit board body 1 has a wastewater passage inside, which is connected to the internal passage of the wastewater ratio adjustable valve 2. The water circuit board body 1 has a valve seat 11, which is provided with a first flow hole 111 and a second flow hole 112. Both the first flow hole 111 and the second flow hole 112 are located on the wastewater passage. The inner wall of the first flow hole 111 has an inclined groove 1111, and the inner diameter of the groove 1111 gradually decreases from the outside to the inside. The wastewater ratio... The adjustable valve 2 includes a valve core 21, a sealing cover 22, and a drive mechanism 23. The valve core 21 has an abutment portion 211, which is correspondingly disposed with a first flow hole 111. The abutment portion 211 can move in a direction close to or away from the first flow hole 111 to change the flow rate of the first flow hole 111. The sealing cover 22 is installed on the valve seat 11, and the valve core 21 passes through and slides on the sealing cover 22. A channel 12 is formed between the sealing cover 22 and the valve seat 11, and the channel 12 connects the first flow hole 111 and the second flow hole 112. The drive mechanism 23 is used to drive the valve core 21 to move.
[0062] like Figures 1-7 As shown, the water circuit board has a wastewater ratio adjustable valve 2 installed on the internal wastewater passage. Since both the first flow hole 111 and the second flow hole 112 are located on the wastewater passage, the first flow hole 111 on the valve seat 11 is connected to one end of the wastewater passage, and the second flow hole 112 on the valve seat 11 is connected to the other end of the wastewater passage. The wastewater passage is connected through the internal passage of the wastewater ratio adjustable valve 2. Since the inner wall of the first flow hole 111 has an inclined groove 1111, the inner diameter of the groove 1111 gradually decreases from the outside to the inside. When the abutment part 211 of the valve core 21 moves towards the first flow hole 111, the gap between the abutment part 211 and the first flow hole decreases, and the flow rate of the first flow hole 111 decreases accordingly. When the abutment part 211 of the valve core 21 moves away from the first flow hole 111, the gap between the abutment part 211 and the first flow hole increases, and the flow rate of the first flow hole 111 increases accordingly. The drive mechanism adjusts the flow rate of the first flow hole 111 by driving the valve core, thereby changing the flow rate of the wastewater passage and adjusting the wastewater flow rate. This allows users to adjust the wastewater volume as needed and obtain purified water with different mineral contents.
[0063] For example, in areas with good water quality, the flow rate of the wastewater passage can be reduced by adjusting the wastewater ratio adjustable valve 2, thereby reducing wastewater volume. Conversely, in areas with relatively high ion content in the water, the flow rate of the wastewater passage can be increased by adjusting the wastewater ratio adjustable valve 2, thereby improving the membrane's retention rate and reducing the ion content in the purified water.
[0064] like Figure 3 As shown, the first flow hole 111 includes a first section 1112 and a second section 1113 along the depth direction. A groove 1111 is located in the first section 1112, and the abutment portion 211 seals the first flow hole 111 when it moves to the second section 1113. Since the inner diameter of the groove 1111 gradually decreases from the outside to the inside, the abutment portion 211 adjusts the flow rate of the first flow hole 111 when it moves within the first section 1112. Since the second section 1113 does not have a groove 1111, the abutment portion 211 closes the first flow hole 111 when it moves to the second section 1113.
[0065] like Figure 2 and Figure 3 As shown, the edge of the first flow hole 111 is also provided with a chamfer 1114. The chamfer 1114 is used to guide the abutment part 211 to slide into the first flow hole 111, so as to prevent the abutment part 211 from not being aligned with the first flow hole 111, and thus failing to seal and close the first flow hole 111.
[0066] like Figures 2-4 As shown, the water circuit board body 1 has a recess 13, a valve seat 11 is located at the bottom of the recess 13, and a sealing cover 22 is embedded in the recess 13, with the outer peripheral surface of the sealing cover 22 abutting against the inner wall of the recess 13. By placing the valve seat 11 at the bottom of the recess 13 and limiting the sealing cover 22 by the inner wall of the recess 13, it is easy to install and fix the sealing cover 22, and also to facilitate the sealing connection between the sealing cover 22 and the valve seat 11.
[0067] like Figures 2-7 As shown, the wastewater ratio adjustable valve 2 also includes a sealing element 24, which is sleeved on the outside of the abutment portion 211. The outer peripheral surface of the sealing element 24 abuts against the inner wall of the first flow hole 111. When the abutment portion 211 moves to the second section 1113, the sealing element 24, by sleeved on the outside of the abutment portion 211, seals the gap between the abutment portion 211 and the first flow hole 111, improving the sealing effect when the abutment portion 211 closes the first flow hole 111. Preferably, the sealing element is a rubber sealing ring to improve the sealing effect.
[0068] like Figure 3 and Figure 7As shown, the wastewater ratio adjustable valve 2 also includes a first sealing ring 25. The first sealing ring 25 is embedded in a through hole in the sealing cover 22, and is sleeved on the valve core 21. The outer circumferential surface of the first sealing ring 25 abuts against the sealing cover 22. By providing the first sealing ring 25 between the valve core 21 and the sealing cover 22, the sealing effect between the valve core 21 and the sealing cover 22 is improved, preventing water from leaking out from the gap between the valve core 21 and the sealing cover 22.
[0069] Since the valve core 21 slides on the sealing cover 22 and the first sealing ring 25 is fixed on the sealing cover, even if the valve core 21 slides back and forth, the first sealing ring and the sealing cover 22 remain relatively fixed, and the water in the sealing cover 22 will not leak out from the connection between the valve core and the sealing cover.
[0070] like Figure 3 and Figure 7 As shown, the wastewater ratio adjustable valve 2 also includes a second sealing ring 26. The second sealing ring 26 is sleeved on the outer peripheral surface of the sealing cover 22, and the outer peripheral surface of the second sealing ring 26 abuts against the inner wall of the recess 13. The second sealing ring 26 is sleeved on the outer peripheral side of the sealing cover 22 and is used to seal the gap between the inner wall of the recess 13 and the sealing cover 22, preventing water leakage from the gap between the outer peripheral side of the sealing cover 22 and the inner wall of the recess 13, thereby improving the sealing effect.
[0071] like Figure 3 and Figure 7 As shown, the wastewater ratio adjustable valve 2 also includes a third sealing ring 27. The third sealing ring 27 is disposed between the sealing cover 22 and the valve seat 11. The third sealing ring 27 is embedded in the groove on the valve seat 11 or the groove on the sealing cover 22, improving the fixing effect of the third sealing ring 27. The third sealing ring 27 is disposed between the sealing cover 22 and the valve seat 11, and is pressed onto the valve seat 11 by the sealing cover 22, preventing water from leaking out from the gap between the sealing cover 22 and the valve seat 11, thus improving the sealing effect.
[0072] like Figures 1-7 As shown, the wastewater ratio adjustable valve 2 also includes a pressure cap 28. The pressure cap 28 is installed on the water circuit board body 1 by fasteners. The pressure cap 28 is sleeved on the valve core 21 and embedded in the recess 13. The lower edge of the pressure cap 28 abuts against the upper edge of the sealing cover 22. The pressure cap 28 is installed on the water circuit board body 1 by fasteners. The pressure cap 28 limits and fixes the sealing cover 22 to the valve seat 11, which facilitates the installation and removal of the sealing cover 22 and also improves the fixing effect of the sealing cover 22.
[0073] like Figure 3 and Figure 7As shown, the wastewater ratio adjustable valve 2 also includes a threaded component 29, which is installed on the outside of the sealing cover 22. The valve core 21 passes through and is threadedly connected to the threaded component 29. The drive mechanism 23 is connected to the valve core 21 and is used to drive the valve core 21 to rotate. The valve core 21 is threadedly connected to the threaded component 29, which fixes the valve core 21. Simultaneously, by rotating the valve core 21, it can move towards or away from the valve seat 11 with the cooperation of the threaded component 29, thereby adjusting the flow rate of the first flow hole 111. In this embodiment, the threaded component is a nut. In other embodiments, the threaded component may be other components with threaded holes.
[0074] In this embodiment, the drive mechanism 23 includes a motor, the output shaft of which is connected to the valve core 21. The motor drives the valve core 21 to rotate. The motor can be electrically connected to a controller, which controls the rotation of the motor, facilitating automatic control and adjusting the size of the wastewater passage.
[0075] In another alternative embodiment, the drive mechanism includes a knob mounted on the end of the valve core, which can be manually rotated to adjust the size of the wastewater passage, making operation simple and convenient.
[0076] This embodiment also discloses a water purifier, which includes the water circuit board as described above.
