Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a water circuit control valve and a water softener. Background Technology

[0002] In existing technologies, water softeners are equipped with water circuit control valves to switch water circuits and meet various operating conditions of the water softener. These valves typically consist of a drive component, a valve core, and a valve sleeve. The drive component moves the valve core reciprocally relative to the valve sleeve, thus switching the water circuit. However, during this movement, the valve core can easily detach from the valve sleeve, leading to a risk of leakage. Furthermore, the drive component's direction needs to be adjusted to achieve the reciprocating movement of the valve core, making operation complex.

[0003] Therefore, there is an urgent need for a water circuit control valve and a water softener to solve the above problems. Utility Model Content

The mating surface abuts against the inner bottom wall of the helical reciprocating groove and moves along the inner bottom wall of the helical reciprocating groove. The driving surface abuts against the inner side wall of the helical reciprocating groove and drives the valve core assembly to reciprocate relative to the valve sleeve assembly.

[0011] As an optional embodiment, the rotating component has a first mounting hole extending radially along the valve core assembly, the first mounting hole communicating with the helical reciprocating groove, the pushing component being located in the first mounting hole, and the driving assembly further comprising:

[0012] A first plug is installed at the end of the first mounting hole that is away from the valve core assembly;

[0013] An elastic element is sandwiched between the first plug and the pusher so that the mating surface elastically abuts against the inner bottom wall of the helical reciprocating groove.

[0014] As an optional solution, a groove is provided on one of the inner cavity wall of the valve sleeve assembly and the outer peripheral wall of the valve core assembly, and the other of the inner cavity wall of the valve sleeve assembly and the outer peripheral wall of the valve core assembly includes a guide protrusion.

[0022] The beneficial effects of this utility model are:

[0023] This invention provides a water circuit control valve, which includes a valve sleeve assembly, a valve core assembly, and a drive assembly. The valve core assembly is slidably disposed within the valve sleeve assembly and reciprocates relative to the valve sleeve assembly along its axial direction. A helical reciprocating groove is provided on the outer peripheral wall of the valve core assembly. The drive assembly includes a drive component, a rotating component, and a pushing component. The rotating component is rotatably connected to the valve sleeve assembly, and the pushing component is disposed on the rotating component. The pushing component extends into and moves along the helical reciprocating groove. The drive component is drively connected to the rotating component and is used to drive the rotating component to rotate relative to the valve sleeve assembly. The water circuit control valve provided by this invention drives the rotating component to rotate, which in turn drives the pushing component to rotate. This causes the pushing component to push the valve core assembly to reciprocate along its axial direction relative to the valve sleeve assembly along the helical reciprocating groove, thereby achieving water circuit switching. When the pushing component moves along the helical reciprocating groove to its end, the valve core assembly moves to its limit position axially. If the driving component continues to drive the rotating component to rotate in the same direction, the pushing component begins to move in the opposite direction from the end of the helical reciprocating groove, causing the valve core assembly to also move in the opposite direction. This effectively prevents the valve core assembly from detaching from the valve sleeve assembly, thus avoiding the safety hazard of water leakage and making the water control valve safer and more reliable. Furthermore, this design allows the driving component to drive the rotating component to rotate in one direction, which in turn drives the pushing component to reciprocate the valve core assembly without changing the driving direction of the driving component, making operation convenient.

[0024] This utility model also provides a water softener. By applying the above-mentioned water circuit control valve, the water softener avoids the valve core assembly from detaching from the valve sleeve assembly, thus avoiding the risk of water leakage and making the water circuit control valve safer and more reliable. Furthermore, the drive component can drive the rotating component to rotate in one direction, which in turn drives the valve core assembly to move back and forth through the push component. There is no need to change the driving direction of the drive component, making operation convenient. Attached Figure Description

[0038] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0039] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0041] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0042] Existing water circuit control valves typically include a drive element, a valve core, and a valve sleeve. The drive element moves the valve core reciprocally relative to the valve sleeve, thereby switching water circuits. However, during the movement of the valve core relative to the valve sleeve, the valve core is prone to detaching from the valve sleeve, ultimately leading to the risk of leakage. Furthermore, the drive element's direction needs to be adjusted to achieve the reciprocating movement of the valve core, making operation complex.

[0043] To solve the above problems, such as Figures 1-4As shown, this embodiment provides a water circuit control valve, which includes a valve sleeve assembly 1, a valve core assembly 2, and a drive assembly 3. The valve core assembly 2 is slidably disposed within the valve sleeve assembly 1 and reciprocates relative to the valve sleeve assembly 1 along its axial direction (left-right direction in the figure). A helical reciprocating groove 221 is provided on the outer peripheral wall of the valve core assembly 2. The drive assembly 3 includes a drive member 31, a rotating member 32, and a pushing member 33. The rotating member 32 is rotatably connected to the valve sleeve assembly 1, and the pushing member 33 is provided on the rotating member 32. The pushing member 33 extends into the helical reciprocating groove 221 and moves along the helical reciprocating groove 221. The drive member 31 is drively connected to the rotating member 32 and is used to drive the rotating member 32 to rotate relative to the valve sleeve assembly 1. The water circuit control valve provided in this embodiment drives the rotating component 32 to rotate via the driving component 31. The rotating component 32 then drives the pushing component 33 to rotate, causing the pushing component 33 to push the valve core assembly 2 to reciprocate along its axial direction relative to the valve sleeve assembly 1 along the helical reciprocating groove 221. This achieves water circuit switching and effectively avoids the problem of the valve core assembly 2 detaching from the valve sleeve assembly 1, thus preventing the safety hazard of water leakage and making the water circuit control valve safer and more reliable. Furthermore, the driving component 31 can drive the rotating component 32 to rotate in one direction, which in turn drives the valve core assembly 2 to reciprocate, without needing to change the driving direction of the driving component 31, making operation convenient.

[0044] Specifically, such as Figures 2-4 As shown, when the driving member 31 drives the rotating member 32 to rotate, the rotating member 32 drives the pushing member 33 to rotate, so that the pushing member 33 moves along the helical reciprocating groove 221 to the end of the helical reciprocating groove 221. At this time, the valve core assembly 2 moves to the limit position in the axial direction. If the driving member 31 continues to drive the rotating member 32 to rotate in the same direction, the pushing member 33 starts to move in the opposite direction from the end of the helical reciprocating groove 221, so that the valve core assembly 2 also starts to move in the opposite direction. This not only prevents the valve core assembly 2 from disengaging from the valve sleeve assembly 1, but also ensures that when the driving member 31 drives the rotating member 32 to rotate in one direction, the valve core assembly 2 achieves reciprocating movement in the axial direction.

[0045] It should be noted that the helical reciprocating groove 221 includes a first helical groove and a second helical groove. Both the first helical groove and the second helical groove extend along the axial direction of the valve core assembly 2. The first helical groove and the second helical groove are arranged intersectingly on the outer peripheral wall of the valve core assembly 2, and the first helical groove and the second helical groove have opposite directions of rotation. The end of the first helical groove is connected to the beginning of the second helical groove, and the beginning of the first helical groove is connected to the end of the second helical groove. When the rotating member 32 drives the pushing member 33 to rotate, causing the pushing member 33 to move along the first spiral groove to the end of the first spiral groove, the valve core assembly 2 moves to one of its extreme positions in the axial direction. If the driving member 31 continues to drive the rotating member 32 to rotate in the same direction, the pushing member 33 moves from the end of the first spiral groove to the beginning of the second spiral groove and moves along the second spiral groove, causing the valve core assembly 2 to also begin to move in the opposite direction. When the pushing member 33 moves along the second spiral groove to the end of the second spiral groove, the valve core assembly 2 moves to another extreme position in the axial direction. If the driving member 31 continues to drive the rotating member 32 to rotate in the same direction, the pushing member 33 moves from the end of the second spiral groove to the beginning of the first spiral groove and moves along the first spiral groove, and so on.

[0046] It should be noted that, in this embodiment, the water circuit control valve can be applied to a water softener. By reciprocating the movement of the valve core assembly 2 relative to the valve sleeve assembly 1, the water circuit is switched to meet the various states of water softening and resin regeneration in the water softener. Since the specific structure and principle of the water circuit switching achieved by the reciprocating movement of the valve core assembly 2 relative to the valve sleeve assembly 1 are prior art, they will not be described in detail here. In other embodiments, this water circuit control valve can also be applied to other equipment.

[0047] In this embodiment, as Figure 1 and Figure 2 As shown, the valve core assembly 2 includes a valve core body 21 and a pull rod 22 connected together. A helical reciprocating groove 221 is provided on the outer peripheral wall of the pull rod 22. The valve sleeve assembly 1 includes a valve sleeve 11 and a mounting base 12 fixedly connected together. A rotating component 32 is rotatably connected to the mounting base 12, and the water circuit switching is achieved through the reciprocating movement of the valve core body 21 relative to the valve sleeve 11 within the valve sleeve 11. Specifically, in this embodiment, the driving component 31 is fixedly disposed on the mounting base 12, and the interior of the mounting base 12 is a through cavity, thereby ensuring that the pull rod 22 slides through the interior of the mounting base 12.

[0048] Optionally, in this embodiment, as Figure 3 and Figure 4As shown, the pusher 33 includes a mating surface 331 and a driving surface 332 connected to each other. The mating surface 331 abuts against the inner bottom wall 2211 of the helical reciprocating groove 221, and the mating surface 331 moves along the inner bottom wall 2211 of the helical reciprocating groove 221. The driving surface 332 abuts against the inner side wall 2212 of the helical reciprocating groove 221, and the driving surface 332 drives the valve core assembly 2 to reciprocate relative to the valve sleeve assembly 1. The above-mentioned structural design of the pusher 33 not only ensures the stability of the movement of the pusher 33 relative to the helical reciprocating groove 221, but also ensures the pushing effect of the pusher 33 on the pull rod 22. Optionally, the mating surface 331 is arc-shaped, and the shape of the mating surface 331 is adapted to the shape of the inner bottom wall 2211 of the helical reciprocating groove 221, thereby ensuring the tightness of the abutment between the mating surface 331 and the inner bottom wall 2211, and thus ensuring the reliability of the movement of the mating surface 331 along the helical reciprocating groove 221. Optionally, the pusher 33 includes two driving surfaces 332, which are located on opposite sides of the pusher 33 along the axial direction of the valve core assembly 2. When the pusher 33 pushes the pull rod 22 to the left, the driving surface 332 on the left abuts against the inner wall 2212 of the corresponding side. When the pusher 33 pushes the pull rod 22 to the right, the driving surface 332 on the right abuts against the inner wall 2212 of the corresponding side.

[0049] Optionally, such as Figure 2 and Figure 5 As shown, the rotating component 32 has a first mounting hole 321 extending radially along the valve core assembly 2. The first mounting hole 321 communicates with the helical reciprocating groove 221. The pushing component 33 is located in the first mounting hole 321. The driving component 3 also includes a first plug 34 and an elastic component 35. The first plug 34 is installed at the end of the first mounting hole 321 away from the valve core assembly 2. The elastic component 35 is sandwiched between the first plug 34 and the pushing component 33, so that the mating surface 331 elastically abuts against the inner bottom wall 2211 of the helical reciprocating groove 221. By setting the elastic component 35, the mating surface 331 elastically abuts against the inner bottom wall 2211, which not only ensures the reliability of the movement of the mating surface 331 along the inner bottom wall 2211, but also avoids contact damage between the mating surface 331 and the inner bottom wall 2211, and also ensures the smoothness of the movement of the pushing component 33 relative to the helical reciprocating groove 221. Furthermore, by providing the first plug 34, the elastic element 35 and the pushing element 33 are prevented from dislodging from the first mounting hole 321, ensuring the reliability of the installation. Optionally, the elastic element 35 is a spring sheet; in other embodiments, the elastic element 35 can also be a spring. Optionally, in this embodiment, the drive assembly 3 further includes a first fastener 38, which detachably mounts the first plug 34 in the first mounting hole 321, thereby facilitating the removal of the first plug 34 from the first mounting hole 321 for replacement of the elastic element 35 and the pushing element 33. Optionally, the first fastener 38 can be a bolt.

[0050] Optionally, in this embodiment, as Figure 6 As shown, a groove 222 is provided on one of the inner wall of the valve sleeve assembly 1 and the outer peripheral wall of the valve core assembly 2, and the other of the inner wall of the valve sleeve assembly 1 and the outer peripheral wall of the valve core assembly 2 includes a guide protrusion 121. The guide protrusion 121 extends along the axial direction of the valve core assembly 2, and the guide protrusion 121 and the groove 222 are slidably connected. By providing the slidably connected guide protrusion 121 and groove 222, the reciprocating movement of the valve core assembly 2 relative to the valve sleeve assembly 1 is guided, avoiding circumferential rotation of the valve core assembly 2 relative to the valve sleeve assembly 1, and ensuring the reliability of the reciprocating movement of the valve core assembly 2 relative to the valve sleeve assembly 1. In this embodiment, the inner wall of the valve sleeve assembly 1 includes the guide protrusion 121, and the outer peripheral wall of the valve core assembly 2 has a groove 222. Specifically, the inner wall of the mounting base 12 includes the guide protrusion 121, and the outer peripheral wall of the pull rod 22 has a groove 222. Optionally, the inner wall of the mounting base 12 includes two guide protrusions 121 arranged opposite to each other, and the outer peripheral wall of the pull rod 22 has two opposing sliding grooves 222. The two guide protrusions 121 and the two sliding grooves 222 correspond one-to-one, further ensuring the reliability of the reciprocating movement of the valve core assembly 2 relative to the valve sleeve assembly 1. In other embodiments, the inner wall of the valve sleeve assembly 1 may also have sliding grooves 222, and the outer peripheral wall of the valve core assembly 2 may include guide protrusions 121.

[0051] Optionally, in this embodiment, as Figure 2 and Figure 7 As shown, the rotating component 32 is rotatably sleeved on the outer periphery of the valve sleeve assembly 1. The outer peripheral wall of the valve sleeve assembly 1 has an annular limiting groove 122. The rotating component 32 has a second mounting hole 322 communicating with the annular limiting groove 122. The driving assembly 3 also includes a limiting ball 36, which is housed in the second mounting hole 322 and rolls along the annular limiting groove 122. By allowing the limiting ball 36 to roll along the annular limiting groove 122 in the second mounting hole 322, not only is the smooth rotation of the rotating component 32 relative to the valve sleeve assembly 1 ensured, but also the axial direction of the rotating component 32 relative to the valve sleeve assembly 1 is limited, preventing axial displacement of the rotating component 32 relative to the valve sleeve assembly 1. Specifically, in this embodiment, the outer peripheral wall of the mounting base 12 has an annular limiting groove 122.

[0052] Optionally, in this embodiment, as Figure 7As shown, the drive assembly 3 also includes a second plug 37, which is fixed in the second mounting hole 322 to seal the limiting ball 36 in the second mounting hole 322. By providing the second plug 37, the limiting ball 36 is prevented from coming out of the second mounting hole 322, ensuring the reliability of the installation. Optionally, in this embodiment, the drive assembly 3 also includes a second fastener 39, which detachably mounts the second plug 37 in the second mounting hole 322, thereby facilitating the removal of the second plug 37 from the second mounting hole 322 for replacement of the limiting ball 36. Optionally, the second fastener 39 can be a bolt.

[0053] Optionally, in this embodiment, as Figure 1 and Figure 8 As shown, the driving component 31 includes a driving motor 311 and a driving gear 312 fixedly connected to the output shaft of the driving motor 311. The rotating component 32 is a transmission gear, and the driving gear 312 meshes with the transmission gear for transmission. The transmission connection between the driving motor 311 and the pushing component 33 is realized through the driving gear 312 and the transmission gear, ensuring the accuracy of the transmission ratio, thereby making it easier to control, adjust, and monitor the reciprocating position of the valve core assembly 2 relative to the valve sleeve assembly 1. Specifically, in this embodiment, the driving motor 311 is fixedly mounted on the mounting base 12. In addition, it should be noted that due to the cooperation between the helical reciprocating groove 221 and the pushing component 33, it is not necessary for the driving motor 311 to rotate in both directions; simply rotating the driving motor 311 in one direction is sufficient to achieve the reciprocating movement of the valve core assembly 2 in the axial direction.

[0054] Optionally, in this embodiment, as Figure 8 As shown, the water control valve also includes a detection component 4, which includes a sensor switch 41. The sensor switch 41 is disposed on the valve sleeve assembly 1, and the end of the valve core assembly 2 extending out of the valve sleeve assembly 1 can trigger the sensor switch 41. When the end of the valve core assembly 2 extending out of the valve sleeve assembly 1 triggers the sensor switch 41, it indicates that the valve core assembly 2 has moved to the limit position on one side along the axial direction, which facilitates the detection of the movement position of the valve core assembly 2. Optionally, in this embodiment, when the end of the valve core assembly 2 extending out of the valve sleeve assembly 1 triggers the sensor switch 41, the position of the valve core assembly 2 at this time can be positioned as zero. Specifically, in this embodiment, the end of the pull rod 22 extending out of the valve sleeve assembly 1 can trigger the sensor switch 41. Specifically, in this embodiment, the sensor switch 41 is fixedly installed on the mounting base 12 by fastening screws and mounting plate, and the sensor switch 41 is located on the right end side of the pull rod 22. When the end of the pull rod 22 extending out of the valve sleeve assembly 1 triggers the sensor switch 41, it indicates that the valve core assembly 2 has moved to the right to the limit position, i.e., the zero position.

[0055] Optionally, in this embodiment, the detection component 4 further includes a photosensitive element 42 and a reflector 43. A plurality of light-transmitting holes 323 are spaced apart on the rotating component 32, and these holes are evenly spaced circumferentially along the rotation center of the rotating component 32. Both the photosensitive element 42 and the reflector 43 are disposed on the valve sleeve assembly 1, and are arranged opposite to each other on both sides of the rotating component 32. Light emitted from the photosensitive element 42 shines through the light-transmitting holes 323 onto the reflector 43. This arrangement allows the light emitted from the photosensitive element 42 to receive corresponding pulses when it shines through the light-transmitting holes 323 onto the reflector 43, thereby detecting the rotation angle and number of rotations of the rotating component 32. This enables the calculation of the pitch of the pull rod 22 based on the pulses, and thus the determination of the displacement position of the valve core assembly 2. Specifically, in this embodiment, both the light sensor 42 and the reflector 43 are disposed on the mounting base 12, and the light sensor 42 and the reflector 43 are arranged opposite to each other on both sides of the rotating member 32 in the axial direction.

[0056] This embodiment also provides a water softener, which includes a main body and the aforementioned water control valve. The water control valve is installed on the main body. By using the aforementioned water control valve, the water softener provided in this embodiment avoids the valve core assembly 2 from detaching from the valve sleeve assembly 1, thus preventing the risk of leakage and making the water control valve safer and more reliable. Furthermore, the drive member 31 drives the rotating member 32 to rotate in one direction, which in turn drives the valve core assembly 2 to reciprocate via the push member 33, without needing to change the driving direction of the drive member 31, making operation convenient. It should be noted that the reciprocating movement of the valve core assembly 2 relative to the valve sleeve assembly 1 achieves water circuit switching, satisfying various states of water softening and resin regeneration in the water softener.
