Description

Technical Field

[0001] This utility model relates to the field of valve core technology, and in particular to a water purification valve core. Background Technology

[0002] Faucets, especially those specifically designed for water purification, are common household appliances. Their internal structure includes a crucial component: a water purification valve core. Adjusting this valve core allows for precise control of water flow. Currently, some faucets on the market are equipped with advanced indicator lights. Specifically, when water begins to flow, the indicator light automatically illuminates. This design primarily serves as a visual indicator, allowing users to intuitively understand the faucet's current status and thus more easily control the water flow. However, this design has certain drawbacks in practical application, mainly due to insufficient sensitivity of the indicator light. Typically, the indicator light is fixed externally to the faucet, while a sensor is located on the water purification valve core that works in conjunction with the indicator light. When the user turns the faucet, it rotates the internal water purification valve core. When the faucet is fully open, the sensor outputs a corresponding signal, triggering the control circuit and illuminating the indicator light. In other words, the indicator light is conditional; it only illuminates when the faucet is fully open. However, in reality, water starts flowing even before the faucet is fully open. In this situation, the indicator light's function is not timely or accurate enough, because users can use the water flow before the faucet is fully open, while the indicator light only illuminates the moment the faucet is fully open. Therefore, it needs improvement. Utility Model Content

[0003] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a water purification valve core with a simple and reasonable structure and convenient operation. A magnet is installed on the rotating seat. When the rotating seat reaches a set angle, the magnet magnetically engages with the detection element outside the water purification valve core and triggers an induction signal. That is, the rotating seat does not need to be rotated to the maximum angle to generate an induction signal.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This utility model discloses a water purification valve core, comprising a housing, a valve cover, and a valve plate. The housing is fixedly connected to the valve cover, and the valve plate is fixedly disposed within the housing. The valve cover has an inlet and an outlet, and the valve plate has a first water passage hole aligned with and communicating with the inlet and a second water passage hole aligned with and communicating with the outlet. It also includes a rotating column and a rotating seat. The rotating column is rotatably disposed within the housing, and a rotation limiting structure is provided between the rotating column and the housing to limit the rotation angle of the rotating column. The lower end of the rotating column is kinetically connected to the rotating seat, which is disposed above the valve plate. The rotating seat has a water passage cavity communicating with the first water passage hole. The water passage cavity is configured such that when the rotating seat is in its initial state, the water passage cavity blocks the second water passage hole; when the rotating seat rotates, the water passage cavity communicates with the second water passage hole. A magnet is fixedly disposed on the rotating seat, and the magnet is configured such that when the rotating seat rotates to a set angle, the magnet can magnetically cooperate with an external detection element, causing the detection element to generate a sensing signal.

[0006] Furthermore, the set angle is less than or equal to 35 degrees.

[0007] Furthermore, the set angle is designed to be 19 to 20 degrees.

[0008] Furthermore, the set angle is designed to be 20 degrees.

[0009] Furthermore, the rotation limiting structure includes at least one first limiting block disposed on the inner wall of the outer shell and at least one second limiting block disposed on the outer wall of the rotating column, wherein the first limiting block and the second limiting block are in a limiting engagement.

[0010] Furthermore, a third limiting block is provided on the inner wall of the outer shell, wherein a limiting step is provided on one of the second limiting blocks, and the third limiting block cooperates with the limiting step to limit the axial movement of the rotating column within the outer shell.

[0011] Furthermore, the maximum rotation angle of the rotating column is 90 degrees.

[0012] Furthermore, the upper openings of the first and second water passages are fan-shaped.

[0013] Furthermore, the rotating column is provided with a magnet mounting groove for mounting magnets, and the rotating seat is provided with a clearance groove that corresponds to and cooperates with the magnet mounting groove.

[0014] Furthermore, the lower end of the rotating column is provided with several insert blocks, and the rotating seat is provided with slots that correspond to and cooperate with the insert blocks, and the insert blocks are inserted into the slots.

[0015] The beneficial effects of this utility model are as follows: A water purifier valve core of this utility model has a magnet fixedly installed on a rotating base. The magnet is configured such that when the rotating base rotates to a set angle, the magnet can magnetically cooperate with a detection element outside the water purifier valve core, causing the detection element to generate an induction signal. The detection element is a Hall element, which is installed on the faucet. The water purifier valve core is installed inside the faucet. An indicator light that cooperates with the Hall element is also installed on the faucet. By turning the faucet switch, the rotating column rotates, which in turn rotates the rotating base. When the rotating base rotates to the set angle, the Hall element can accurately detect the change in the magnetic field and output an induction signal to trigger the control circuit, causing the indicator light to illuminate. During the water flow process, the indicator light effectively serves as a reminder, allowing the user to intuitively understand the faucet's operating status.

[0016] The water passage chamber is configured such that when the rotating seat is in its initial state, the water passage chamber is blocked from the second water passage hole. When the rotating seat rotates, the water passage chamber connects with the second water passage hole. It should be noted that in the initial stage when the rotating seat just begins to rotate, the water passage area between the water passage chamber and the second water passage hole is very small, and the water flow is limited. When the rotating seat continues to rotate until it reaches the maximum angle, the water passage area between the water passage chamber and the second water passage hole will also increase to the maximum value, and the water flow can pass smoothly. It is worth noting that the faucet starts to flow water before it is fully opened, that is, before the rotating seat has rotated to the maximum angle. Preferably, the set angle is less than or equal to 35 degrees. More preferably, the set angle is finely designed between 19 and 20 degrees to ensure the best sensing effect. More specifically, the set angle is optimized to 20 degrees to ensure that the indicator light can light up in time when the faucet is flowing water, achieving the best prompting effect and user experience. The faucet does not need to be fully opened, that is, the rotating seat does not need to rotate to the maximum angle. When the rotating seat rotates to the set angle, it can enable the detection element to generate a sensing signal and light up the indicator light. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings.

[0028] like Figures 1-9 The water purification valve core shown includes a housing 1, a valve cover 2, and a valve plate 3. The housing 1 is fixedly connected to the valve cover 2. Specifically, see [reference needed]. Figures 2-3 The valve cover 2 is located at the bottom of the outer casing 1. The valve cover 2 extends upwards and has several snap-fit ​​parts 21. The outer casing 1 has snap-fit ​​grooves 11 that engage with the snap-fit ​​parts 21 to ensure a stable and reliable connection. The valve cover 2 extends upwards and has several protrusions 22. The outer casing 1 has corresponding grooves 12 that engage with the protrusions 22, effectively providing positioning. The valve plate 3 is fixedly installed inside the outer casing 1. Preferably, the valve plate 3 is a ceramic valve plate. (See reference...) Figure 5 The valve plate 3 is provided with a notch 31 that corresponds to the snap-fit ​​part 21, and the valve cover 2 is provided with an inlet 25 and an outlet 26 respectively. (See reference) Figure 5The valve plate 3 is provided with a first water passage hole 32 aligned with and communicating with the water inlet 25 and a second water passage hole 33 aligned with and communicating with the water outlet 26. It also includes a rotating column 4 and a rotating seat 5. The rotating column 4 is rotatably disposed within the outer casing 1. A rotation limiting structure is provided between the rotating column 4 and the outer casing 1 to limit the maximum rotation angle of the rotating column 4. Preferably, in this embodiment, the maximum rotation angle of the rotating column 4 is 90 degrees. The lower end of the rotating column 4 is connected to the rotating seat 5, which is disposed above the valve plate 3. (See reference...) Figure 6 The rotating seat 5 is provided with a water passage cavity 53 connected to the first water passage hole 32. The water passage cavity 53 is configured such that when the rotating seat 5 is in its initial state, the water passage cavity 53 is blocked from the second water passage hole 33, and when the rotating seat 5 rotates, the water passage cavity 53 is connected to the second water passage hole 33, thereby realizing the connection and blockage between the first water passage hole 32 and the second water passage hole 33, ensuring that the water flow at the inlet 25 can flow smoothly out of the outlet 26. Preferably, in this embodiment, see... Figures 2-3 A magnet 411 is fixedly installed on the rotating seat 5. The magnet 411 is configured such that when the rotating seat 5 rotates to a set angle, the magnet 411 can magnetically cooperate with the detection element outside the water purification valve core, causing the detection element to generate an induction signal. The detection element is a Hall element, which is installed on the faucet. The water purification valve core is installed inside the faucet. The faucet is also equipped with an indicator light that cooperates with the Hall element. Specifically, turning the faucet switch drives the rotating column 4 to rotate, which in turn drives the rotating seat 5 to rotate. When the rotating seat 5 rotates to a set angle, the Hall element can accurately detect the change in the magnetic field and output an induction signal to trigger the control circuit, causing the indicator light to light up. During the process of water flowing from the faucet, the indicator light can effectively serve as a reminder, allowing the user to intuitively understand the usage status of the faucet.

[0029] It should be noted that in the initial stage when the rotating seat 5 just begins to rotate, the water-passing area between the water-passing cavity 53 and the second water-passing hole 33 is very small, and the water flow is restricted. As the rotating seat 5 continues to rotate until it reaches its maximum angle, the water-passing area between the water-passing cavity 53 and the second water-passing hole 33 will also increase to its maximum value, allowing the water to flow smoothly. It is worth noting that the faucet starts to dispense water before it is fully open, that is, before the rotating seat 5 has reached its maximum angle. Preferably, in this embodiment, the set angle is less than or equal to 35 degrees. More preferably, in this embodiment, the set angle is precisely designed to be between 19 and 20 degrees to ensure the best sensing effect. More specifically, the set angle is optimized to 20 degrees. When the rotating seat 5 rotates to 20 degrees, the faucet usually starts to dispense water, ensuring that the indicator light can light up in time when the faucet dispenses water, achieving the best prompting effect and user experience. The faucet does not need to be fully open, that is, the rotating seat 5 does not need to be rotated to its maximum angle. When the rotating seat 5 rotates to the set angle, it can enable the detection element to generate a sensing signal and light up the indicator light.

[0030] Preferably, see Figure 2 The upper end of the valve cover 2, near the valve plate 3, is provided with a first sealing ring groove 23, and a first sealing ring 231 is provided in the first sealing ring groove 23. (See reference) Figure 3 The lower end of the valve cover 2 is provided with a second sealing ring groove 24, and a second sealing ring 241 is provided in the second sealing ring groove 24, which can effectively achieve the sealing effect.

[0031] Preferably, see Figures 2-3 The rotating column 4 is provided with a magnet mounting groove 41 for installing a magnet 411, which can ensure the stability of the magnet 411 after installation. The rotating seat 5 is provided with a clearance groove 51 that corresponds to and cooperates with the magnet mounting groove 41. The clearance groove 51 corresponds to the magnet mounting groove 41 in position and size.

[0032] Preferably, in this embodiment, refer to Figure 7 The rotation limiting structure includes at least one first limiting block 14 disposed on the inner wall of the outer shell 1 and at least one second limiting block 42 disposed on the outer wall of the rotating column 4. The first limiting block 14 and the second limiting block 42 cooperate to limit the maximum rotation angle of the rotating column 4.

[0033] Preferably, in this embodiment, refer to Figure 7 The inner wall of the outer shell 1 is also provided with a third limiting block 15, and one of the second limiting blocks 42 is provided with a limiting step 421. The third limiting block 15 and the limiting step 421 are matched to limit the axial movement of the rotating column 4 in the outer shell 1.

[0034] Preferably, in this embodiment, refer to Figure 2 The upper openings of the first water passage 32 and the second water passage 33 are fan-shaped, which can better adapt to the rotation of the rotating seat 5. The rotation of the rotating seat 5 controls the connection and blockage between the first water passage 32 and the second water passage 33.

[0035] Preferably, in this embodiment, refer to Figure 2 An arrow 13 is provided on the outer shell 1, and the arrow 13 is aligned with the initial angle of the rotating column 4, so that the user can easily identify the starting position of the rotating column 4 during use.

[0036] Preferably, in this embodiment, refer to Figure 8 The lower end of the rotating column 4 is provided with several insert blocks 43, and the rotating seat 5 is provided with slots 52 that correspond to and cooperate with the insert blocks 43. The insert blocks 43 and slots 52 are inserted and cooperated to ensure the stable and reliable connection between the rotating column 4 and the rotating seat 5.
