Description

Technical Field

[0001] The utility model relates to the field of switch valve cores, in particular to an inductive switch valve core. Background Art

[0002] The valve cores currently on the market can be applied to a variety of usage scenarios, such as shower equipment or water purifier equipment. Common valve cores usually include a rotating shaft. People install the valve core in the corresponding structural position according to different usage scenarios, and set the control switch on the rotating shaft handle. By rotating the control switch, the rotating shaft handle rotates, thereby controlling the change of the internal passage structure of the valve core to realize the opening and closing or switching of the water flow path;

[0003] As people's needs change in the market, more and more people are adding multiple functions to shower equipment and water purifiers. Therefore, valve cores on the market also have switch sensing functions. Taking water purifiers as an example, when the user turns on the water, the sensing mechanism set inside the valve core will open and control the filter device inside the water purifier to start filtering. However, in existing sensing valve cores, the time it takes for the sensing part to reach the sensing position is the same as the time it takes for the switch to reach the working position, but it takes time for the sensing part to trigger the induction. Therefore, after the valve core is opened to form a water flow path, there is a certain delay when the sensing part controls the filter device to open, and the connected device cannot start immediately. During this period, the filter has not yet started. When there is no water flowing through, the internal pressure of the pipeline is high, causing certain damage to the valve core. Other devices on the market that use valve cores may also add functions such as induction lights. Due to the induction delay of the sensing part, the light sensing will be turned on with a lag while water is being used.

[0004] During use, the delayed triggering of the existing induction valve core brings a bad user experience. Utility Model Content

[0030] In order to explain the technical content, structural features, achieved objectives and effects of the technical solution in detail, the following is a detailed description in conjunction with specific embodiments and accompanying drawings. Example 1:

[0031] like Figure 1-8 As shown, a faucet includes an induction switch valve core, the valve core includes a rotating shaft 2, the rotating shaft 2 rotates around the axis and deflects a preset angle to reach the working position, and also includes a sensing component, the sensing component includes a first sensing member 223, the first sensing member 223 is connected to the rotating shaft 2 and rotates synchronously with the rotating shaft 2, the first sensing member 223 deflects a preset angle to reach the sensing position to trigger induction, the deflection angle of the first sensing member 223 to reach the sensing position is smaller than the deflection angle of the rotating shaft 2 to reach the working position. In this embodiment, the rotating shaft 2 rotates around the rotating shaft axis 23. The valve core of this solution is provided with a first sensing member 223 on the rotating shaft 2 to trigger induction. Compared with the prior art, the deflection angle of the first sensing member 223 when reaching the sensing position is smaller than the deflection angle of the rotating shaft 2 when reaching the working position. When the user rotates the control switch to drive the rotating shaft 2 connected to the switch to rotate to the working position to realize water use, the first sensing member 223 reaches the sensing position in advance as the rotating shaft 2 rotates to trigger induction, and controls the connected device to start, which solves the problem in the prior art that the user turns on the switch to use water but the induction lags. The induction lag time of the valve core is short during use, the induction is fast, and the user experience is good.

[0032] like Figure 1-8As shown, in this embodiment, the rotating shaft 2 includes a rotating body 22, which rotates about a rotating shaft axis 23. A first sensing element 223 is disposed on the rotating body 22 and rotates about the rotating shaft axis 23 to reach a sensing position, triggering induction. The rotating body 22 includes a receiving chamber 221, which is disposed within the rotating body 22 and rotates about the rotating shaft axis 23. The first sensing element 223 is disposed within the receiving chamber 221. The rotating body 22 also includes a backup chamber 222, which is disposed within the rotating body 22 and partially rotates about the rotating shaft axis 23. The first sensing element 223 is disposed within the receiving chamber 221 or within the backup chamber 222. In this embodiment, the receiving chamber 221 and the backup chamber 222 are symmetrically located on either side of the axis 23. The rotating shaft 2 also includes a handle 21, which is disposed on the rotating body 22 and connected to the rotating body 22, driving the rotating body 22 to rotate synchronously. The handle 21 rotates about the rotating shaft axis 23. In this embodiment, the handle 21 is provided at the upper end of the rotating body 22. The handle 21 is used to connect to an external switch structure. When a user needs water, they rotate the external control switch, thereby controlling the rotation of the handle 21. The rotation of the handle 21 drives the rotating body 22 to rotate synchronously, and the first sensor 223 then rotates around the axis as the external control switch is turned on. The rotating body 22 is provided with a spare cavity 222. In actual production and use, the user can adjust the installation position of the first sensor 223 according to the actual installation requirements, and install the first sensor 223 in the spare cavity 222, or add the first sensor 223 in the spare cavity 222.

[0033] like Figure 1-8As shown, in this embodiment, a housing 1 is further included, the housing 1 includes a through hole 11 and a mounting cavity 12 , a handle 21 is rotatably arranged on the housing 1 through the through hole 11 , and a rotating body 22 is rotatably arranged inside the mounting cavity 12 . In this embodiment, the valve core also includes a movable plate 3, a fixed plate 4 and a base 5. The movable plate 3 includes a water groove 31 and a water retaining portion 32. The water groove 31 and the water retaining portion 32 are arranged at the bottom of the movable plate 3. The fixed plate 4 includes a water inlet hole 41 and a water outlet hole 42. The base 5 includes a pipeline water inlet mounting hole 51 and a pipeline water outlet mounting hole 52. The pipeline water inlet mounting hole 51 is arranged corresponding to the water inlet hole 41, and the pipeline water outlet mounting hole 52 is arranged corresponding to the water outlet hole 42. The water groove 31 is used to connect the pipeline water inlet mounting hole 51, the water inlet hole 41, the water outlet hole 42 and the pipeline water outlet mounting hole 52. The water retaining portion 32 is used to cut off the connecting path between the pipeline water inlet mounting hole 51, the water inlet hole 41, the water outlet hole 42 and the pipeline water outlet mounting hole 52. In this embodiment, the rotating shaft 2, the movable plate 3, the stator 4 and the base 5 are sequentially installed axially inside the shell 1, the rotating body 22 is arranged inside the shell 1 and is fixedly connected to the movable plate 3 along the circumferential direction, the movable plate 3 and the stator 4 are rotationally connected, the movable plate 3 is rotatably arranged inside the shell 1, the stator 4 and the base 5 are fixedly connected along the circumferential direction, and the base 5 is fixedly connected to the shell 1. Specifically, in this embodiment, the rotating body 22 is disposed within the housing 1 and is fixedly connected to the movable plate 3 along the circumferential direction. A circumferential limiting structure is provided between the rotating body 22 and the movable plate 3. A clamping block 8 is provided circumferentially on the rotating body 22. A bayonet 7 that cooperates with the clamping block 8 of the rotating body 22 is provided on the side of the movable plate 3 adjacent to the rotating body 22. The stator 4 is fixedly connected to the base 5 along the circumferential direction. A circumferential limiting structure is provided between the stator 4 and the base 5. A bayonet 7 is provided circumferentially on the stator 4. A bayonet 7 is provided on the side of the base 5 adjacent to the stator 4 that cooperates with the bayonet 7 of the stator 4. The bayonet 7 is provided on the side wall of the housing 1. The bayonet 8 of the base 5 cooperates with the bayonet 7 of the stator 4 and is fixedly engaged with the bayonet 7 of the housing 2. A sealing member 6 is also provided between the stator 4 and the base 5. In this solution, the rotating shaft 2, the moving plate 3, the stator 4 and the base 5 are stacked in sequence along the axial direction inside the shell 1 and pressed inside the shell 1. When the rotating body 22 rotates, it drives the moving plate 3 which is circumferentially limited by the rotating body 22 to rotate. The moving plate 3 and the stator 4 are rotationally connected. When the moving plate 3 rotates, the stator 4 does not rotate. When the water retaining part 32 at the bottom of the moving plate 3 rotates to a position that does not block the water inlet through hole 41 and the water outlet through hole 42 of the stator 4, the pipeline water inlet mounting hole 51, the water inlet through hole 41, the water trough 31, the water outlet through hole 42 and the pipeline water outlet mounting hole 52 form a water flow path, and the valve core is opened. When the water retaining part 32 at the bottom of the moving plate 3 rotates to the position of the water inlet through hole 41 or the water outlet through hole 42, no water flow path can be formed between the pipeline water inlet mounting hole 51, the water inlet through hole 41, the water outlet through hole 42 and the pipeline water outlet mounting hole 52, and the valve core is closed.

[0034] like Figure 1-8As shown, in this embodiment, the rotating shaft 2 rotates and deflects around its axis by a preset angle to reach the working position and the sensing position at the same time, or the rotating shaft rotates and deflects around its axis by a preset angle to reach the working position but not the sensing position, and the deflection angle of the first sensing member 223 to reach the sensing position is smaller than the deflection angle of the rotating shaft 2 to reach the working position. The rotating shaft 2 rotates and deflects around its axis by a preset angle to reach the working position and the sensing position at the same time, and the rotating shaft rotates and deflects around its axis by a preset angle to reach the working position and the sensing position at the same time, or the rotating shaft rotates and deflects around its axis by a preset angle to reach the working position but not the sensing position, and the working position of the rotating shaft is designed to be ahead of the sensing position, so that the switch rotation angle can be designed to be smaller, effectively saving the required rotation space. The difference between the deflection angle of the rotating shaft 2 at the working position and the deflection angle of the first sensing element 223 at the sensing position is between 3° and 45°. Within this degree difference, the sensing element senses early, the sensing time is fast, and the sensing critical point is not exceeded. This allows for better control of the faucet's rotational space while meeting water flow requirements. The final angle between the starting position of the switch and the final stop position of the magnet can be no more than 90°, making it suitable for most products on the market. In this embodiment, the first sensing element 223 is connected to the rotating shaft 2 and rotates synchronously with the rotating shaft 2. The first sensing element 223 deflects a preset angle to reach the sensing position, triggering the second sensing element 224 to sense. The first sensing element 223 is a magnet, and the second sensing element 224 is a Hall element. This solution uses Hall elements, which are simple to produce and process. Compared to existing solutions that may use the same sensing element but reduce the sensing hysteresis by strengthening the magnet's magnetism, the production cost is lower. A magnetic column 9 is provided between the first sensing element 223 and the second sensing element 224. The use of the magnetic conductive column 9 can better enhance the induction between the Hall element and the magnet, thereby reducing the restrictions on the relative placement of the Hall element and reducing the difficulty of design and production.

[0035] In this embodiment, the rotating shaft 2 rotates 90° from the initial position A to the working position B, and the first sensing element 223 rotates 85° from the initial position C to the sensing position D. The angle between A and C is 5°, and the angle between C and D is 85°. This arrangement can not only ensure that the first sensing element 223 reaches the sensing position in advance to trigger the sensing, but also control the first sensing element 223 not to trigger the sensing too early, giving the user a better experience. In addition, when the first sensing element and the second sensing element of this solution are combined with magnets and Hall elements, the use effect advantage is more significant. Example 2:

[0036] like Figure 9As shown, the difference between the second embodiment and the first embodiment is that, in this embodiment, the rotating shaft 2 rotates 90° from the initial position A to the working position B, and the first sensing element 223 rotates 51° from the initial position C to the sensing position D. The angle between A and C is 45°, and the angle between C and D is 51°. This arrangement ensures that the first sensing element 223 reaches the sensing position and triggers the induction in advance, while also preventing the first sensing element 223 from triggering the induction prematurely, providing a better user experience. In addition, this solution has a more significant advantage when the first and second sensing elements use magnets and Hall elements for induction. Example 3:

[0037] like Figure 10 As shown, the difference between this third embodiment and the first embodiment is that, in this embodiment, the rotating shaft 2 rotates 90° from the initial position A to the working position B, and the first sensing element 223 rotates 60° from the initial position C to the sensing position D. The angle between A and C is 30°, and the angle between C and D is 60°. This arrangement ensures that the first sensing element 223 reaches the sensing position and triggers the induction in advance, while also preventing the first sensing element 223 from triggering the induction prematurely, providing a better user experience. In addition, this solution has a more significant advantage when the first and second sensing elements use magnets and Hall elements for induction.

[0038] Working principle:

[0039] Install the valve core on the equipment using the valve core, connect the control switch with the valve core shaft 2, rotate the control switch, the valve core shaft 2 rotates with the switch, and then drives the movable plate 3 to rotate with the shaft 2, so that the water groove 31 rotates to the position of the water inlet hole 41 and the water outlet hole 42, and a water flow path is formed between the water inlet hole 41, the water outlet hole 42 and the water groove 31. The water flow can flow from the water inlet hole 41 through the water groove and then flow out from the water outlet hole 43. The pipeline water inlet installation hole 51 and the pipeline water outlet installation hole 52 are installed with external pipelines; when the user turns on the water, the valve core shaft 2 rotates, and the first sensing element 223 on the valve core shaft 2, which is a magnet in this solution, rotates with the shaft to the position of the second sensing element 224 Hall element, triggering the induction and then controlling the corresponding equipment to start.
