The body 10 of this embodiment is generally cylindrical and may be made of stainless steel, cast iron, alloys, or the like. The body 10 may include a top wall 12, a bottom wall 14, and a side wall 16 connected between the top wall 12 and the bottom wall 14.

As shown in FIG. 2, the water flow path may include an inlet passage 110 and an outlet passage 112, the inlet passage 110 extending through the bottom wall 14 and the outlet passage 112 extending through the top wall 12. Specifically, the inlet passage 110 is in communication with an inlet pipe (not shown), and the outlet passage 112 is in communication with the outlet pipe 50. Water enters the inlet passage 110 of the main body 10 from the inlet pipe and is discharged from the outlet pipe 50 through the outlet passage 112.

The accommodation chamber 13 is opened between the water inlet passage 110 and the water outlet passage 112, and communicates with the water inlet passage 110 and the water outlet passage 112. The receiving cavity 13 of the present embodiment extends along a direction substantially perpendicular to the side wall 16, and one end of the receiving cavity 13 penetrates through the side wall 16 to form a mounting opening on the side wall 16.

In the main body 10 of this embodiment, an outer peripheral wall 160 protruding outward of the main body 10 is provided at the outer periphery of the mounting opening with respect to the side wall 16, and a screw thread is provided on the inner surface of the outer peripheral wall 160.

The sidewall of the main body 10 may further have a groove 163, and the groove 163 may be annular, and the groove 163 surrounds the outer peripheral wall 160.

The shape and structure of the main body of the above-mentioned embodiments are only an example of the present invention, and in other embodiments, the main body may also be in other shapes or have other structures, which the present invention does not limit.

In some embodiments, a nut 61 and a jaw 62 are provided at one end of the water inlet passage 110, and the water inlet pipe can be stably coupled to the body 10 by the engagement of the nut 61 and the jaw 62. Further, a packing 63 is provided in the water inlet passage 110 to seal the water inlet pipe to the main body 20, thereby preventing water leakage from the water inlet passage 110 of the main body 10. The number of the sealing rings 63 shown in fig. 2 is two, and in other embodiments, the number of the sealing rings 63 may be one, three, or more than three.

The outlet pipe 50 may have various shapes, for example, a straight pipe shape, a C-bent pipe shape, an L-bent pipe shape, etc. The water outlet pipe 50 may be made of stainless steel, alloy, etc. with high rigidity, or may be a silicone hose or other plastic hose with low rigidity.

For example, a clamping ring 64 is sleeved on the outlet pipe 50 to connect the outlet pipe 10 to the main body 10 by clamping the clamping ring 64 with the main body 10, and to position the outlet pipe 50 along the axial direction of the outlet pipe 50. In addition, a sealing ring 63 is disposed between the main water pipe 50 and the main body 10 to seal the water outlet pipe 50 to the main body 10, thereby preventing water leakage at the end of the water outlet passage 112.

The valve body 20 is connected to the main body 10 by a compression nut 65 and can be opened and closed with respect to the main body 10 to adjust the cross-sectional area of the water flow path. The opening and closing motion of the valve core 20 may be linear motion, rotation or other motion relative to the main body 10.

The valve body 20 shown in fig. 2 is opened and closed by rotating with respect to the main body 10 to adjust the cross-sectional area of the water flow passage. Specifically, the valve body 20 is provided with a water passage 21 inside. When the valve member 20 is rotated to displace, i.e., not to communicate, the water inlet of the water passage 21 with the water inlet passage 110 of the main body 10 or to displace the water outlet of the water passage 21 with the water outlet passage 112 of the main body 10, the water passage 11 in the main body 10 is blocked and the faucet 100 is correspondingly closed. When the valve member 20 is rotated to communicate the water inlet and the water outlet of the water passage 21 with the water inlet passage 110 and the water outlet passage 112, respectively, the water passage 11 in the main body 10 is connected and the faucet 100 is opened. The valve body 20 is opened and closed by rotating relative to the main body 10 to adjust the cross-sectional area of the water flow path, that is, the cross-sectional area of the communication portion between the water inlet and the water inlet path 110 of the water flow path 21 or the cross-sectional area of the communication portion between the water outlet and the water outlet path 112 is adjusted by rotating the valve body 20.

The valve core 20 of the present embodiment is rotatably installed in the accommodation chamber 13. Specifically, the spool 20 of the present embodiment has a substantially cylindrical shape, the spool 20 is divided into a first spool section 22, a second spool section 24, and a third spool section 26 in this order in the axial direction of the spool 20, and the cross-sectional areas of the first spool section 22, the second spool section 24, and the third spool section 26 are gradually reduced, so that a step structure is formed on the surface of the spool 20. The compression nut 65 is fitted over the second spool section 24 of the spool 20. The compression nut 65 is provided with external threads which are engaged with internal threads on the outer peripheral wall 160 of the body 10, thereby trapping the first and second spool segments 22 and 24 of the spool 20 in the accommodation chamber 13.

The valve core 20 is further fixed on the handle 40, so that the handle 40 drives the valve core 20 to open and close relative to the main body 10. The handle 40 of this embodiment is fixedly connected to the third spool section 26 of the spool 10.

Specifically, the handle 40 may include a handle tray 42 and a handle bar 44. The handle tray 42 includes a bottom wall 422 and a side wall 424 attached to the outer periphery of the bottom wall 422. The valve core 20 is fixed to the bottom wall 422. The handle lever 44 is secured to the side wall 424 by a lock nut 66 so that the handle disk 42 can be rotated by turning the handle lever 44 to rotate the valve cartridge 20.

The opening degree detection device 30 detects the opening degree of the valve body 20. The opening degree of the valve body 20 may be the degree of communication between the water passage 21 of the valve body 20 and the water passage 11 of the main body 10. The detection of the opening degree of the valve element 20 can be characterized by the degree of relative movement of the valve element 20 with respect to the body 10. For example, if the opening and closing motion of the valve element 20 is a linear motion with respect to the body 10, the opening degree of the valve element may be determined by detecting a linear displacement of the valve element 20 with respect to the body 10. In the present embodiment, the opening and closing operation of the valve body 20 is a rotation relative to the main body 10, and the opening degree of the valve body 20 can be determined by detecting the rotation angle of the valve body 20 relative to the main body 10.

The opening degree detecting device 30 of the present embodiment may include a magnet 32 and an angle sensor 34. One of the magnet 32 and the angle sensor 34 is fixedly disposed with respect to the main body 10, and the other is linked with the valve core 20, so that when the valve core 20 performs the opening and closing actions with respect to the main body 10, the magnet 32 and the angle sensor 34 relatively rotate, so that the rotation angle of the magnetic field of the magnet 32 sensed by the angle sensor 34 changes with the opening and closing actions of the valve core 20.

In some embodiments, the magnet 32 may be disposed such that the angle of the magnetic field sensed by the angle sensor 34 continuously varies with the opening degree of the valve spool 20, and specifically, the magnet 32 may be disposed such that the angle of the magnetic field sensed by the angle sensor 34 positively correlates with the opening degree of the valve spool 20. That is, the magnet 32 or the angle sensor 34 rotates in synchronization with the valve spool 20, and the rotation angle of the magnetic field coincides with the rotation angle of the valve spool 20.

Specifically, the magnet 32 may be a permanent magnet, and the magnet 32 may be a circular ring, a cylinder, a square block, or the like, which is not limited by the present invention. The magnetization of the magnet 32 is sufficient to have one end N pole and one end S pole. Therefore, the shape of the magnet 32 of the present invention is selected more, and the magnetizing condition is satisfied more easily.

The angle sensor 34 may sense a change in direction of the magnetic field generated by the magnet 32, that is, a rotation angle of the magnetic field, and output a sensing signal, and the sensing signal varies with the change in the rotation angle of the magnetic field. If the angle sensor 34 and the magnet 32 are relatively fixed, the sensing signal is unchanged; when the magnet 32 and the angle sensor 34 rotate relative to each other, the direction of the magnetic field of the magnet changes relative to the angle sensor 34, and the sense signal output from the angle sensor 34 changes according to the change in the rotation angle of the magnetic field. So that the rotation angle of the current magnetic field can be determined according to the sensing signal to determine the rotation angle of the spool 20 with respect to the main body 10.

In some embodiments, the angle sensor 34 may be a Tunneling Magnetoresistive (TMR) angle sensor. Of course, in other embodiments, the angle sensor 34 may be other non-contact rotating magnetic sensors that detect the rotation angle of the magnetic field.

Specifically, as shown in fig. 3, the angle sensor 34 of the present embodiment may include a TMR element, which may include a pinned layer 341, a barrier layer 342, and a magnetic sensing layer 343. The barrier layer 342 is stacked on the fixed layer 341, and the magnetic sensing layer 343 is stacked on the barrier layer 341.

The pinned layer 341 is a ferromagnetic layer, and the magnetization direction of the pinned layer 341 is fixed and does not change with the direction of the external magnetic field. The magnetic sensing layer 343 is also called a free layer, and the magnetic sensing layer 343 is also a ferromagnetic layer, but the magnetization direction of the magnetic sensing layer 343 changes according to the change of the external magnetic field direction. The barrier layer 342 is a thin insulator layer, such as a 1-2 nanometer thick insulator layer. The current passes perpendicularly through the TMR element. When the magnetization direction of the magnetic sensing layer 343 changes with the direction of the applied magnetic field, the resistance of the TMR element changes accordingly with the change of the angle between the magnetic sensing layer 343 and the pinned layer 341, as shown in fig. 4.

The sensing information output by the tunneling magneto-resistance angle sensor and representing the opening degree of the valve element is sensing voltage, and the sensing voltage and the magnetic field angle form a sine or cosine relationship, as shown in fig. 5, wherein the abscissa is the angle of the magnetic field direction of the magnetic sensing layer 343, and the ordinate is the sensing voltage output by the tunneling magneto-resistance angle sensor. In this embodiment, the angle between the magnetic field directions of the magnetic sensing layer 343 and the fixed layer 341 can be determined according to a sine curve or a cosine curve, so that the rotation angle of the valve element 20 relative to the main body 10 can be determined.

In some embodiments, when the magnet 32 and the angle sensor 34 are mounted, the mounting positions of the angle sensor 34 and the magnet 32 are set such that the magnetization direction of the magnetic sensing layer 343 coincides with the magnetic field direction of the fixed layer 341, at which time, the initial angle sensed by the angle sensor 34 is 0; when relative rotation occurs between the angle sensor 34 and the magnet 32, the current angle sensed by the angle sensor 34 is the actual angle of rotation of the magnetic field.

In other embodiments, when the magnet 32 and the angle sensor 34 are mounted, the mounting positions of the angle sensor 34 and the magnet 32 are set such that the magnetization direction of the magnetic sensing layer 343 is different from the magnetic field direction of the fixed layer 341, and at this time, the angle sensor 34 senses an initial angle; when relative rotation occurs between the angle sensor 34 and the magnet 32, the angle sensor 34 senses a current angle, which is the difference between the current angle and the initial angle, i.e., the actual rotation angle of the magnetic field.

The mounting locations of the magnet 32 and the angle sensor 34 may be varied. In various mounting positions, the magnetic sensing layer 343 of the angle sensor 34 lies in a plane that is different from the plane of rotation of the magnet 32. One of the magnet 32 and the angle sensor 34 may be provided on the main body 10. Such as on the peripheral wall 160, on the inner walls of the recess 163, or elsewhere on the body 10. The other of the magnet 32 and the angle sensor 34 may then be disposed on the valve cartridge 20, on the handle 40, and in particular on the handle tray 42, such as on the bottom wall 422 or the side wall 424.

In some embodiments, the faucet 100 may further include a support bracket 70, and the support bracket 70 is fixed to the main body 10 and located at the outer periphery of the valve cartridge 20. The angle sensor 34 or the magnet 32 is disposed on the support bracket 70.

Specifically, in the embodiment shown in fig. 1, 2 and 6, the support bracket 70 is substantially annular and is disposed around the valve core 20. The supporting frame 70 is provided with an installation position-limiting block 71, and the angle sensor 34 is fixed in the installation position-limiting block 71. The magnet 32 is in a ring shape, and the magnet 32 is fixed in the handle disc 42 and sleeved on the periphery of the valve core 20.

In other embodiments, the support bracket 70 may not be provided, and the angle sensor 34 may be directly fixed to the main body 10, as shown in fig. 7.

In other embodiments, the angle sensor 34 may be embedded in the valve core 20, as shown in fig. 8, and the magnet 32 is fixed to the main body 10; alternatively, the angle sensor 34 may also be embedded within the spool 20, and in some embodiments, the angle sensor 34 may be concentric with the spool 20.

In other embodiments, the angle sensor 34 may be fixed to the bottom wall 422 of the handle plate 42, and the magnet 32 is fixed to the main body 10 and disposed around the valve core 20 and the compression nut 65, as shown in fig. 9. Of course, in other embodiments, the angle sensor 34 may be fixed to the side wall 424 or may be centered on the handle tray 42.

In the above embodiment, the magnetic sensing layers 343 of the angle sensor 34 are all in a plane parallel to the rotation plane of the magnet 32. In other embodiments, the magnetic sensing layer 343 of the angle sensor 34 may be in a plane that is perpendicular to the plane of rotation of the magnet 32. For example, the angle sensor 34 may be vertically inserted on the body 10 to face the outer arc of the magnet 32, as shown in fig. 10. It will be appreciated that the angle sensor 34 may also be directed towards the inner arc of the magnet 32.

It should be noted that when the magnet 32 and the angle sensor 34 rotate relatively, the rotation axis may pass through the magnet 32 or the angle sensor 34, or may not pass through the magnet or the angle sensor 34.

In some embodiments, the faucet 100 further includes a display screen (not shown), and information such as the current opening of the valve cartridge of the faucet 100, the current water flow in the water flow path, etc. can be displayed on the display screen of the faucet 100.

The utility model also provides a water processor 200, as shown in fig. 11, this water processor 200 includes water treatment facilities 300, main control unit 400 and the tap 100 of any of the above-mentioned embodiment. The water treatment device 300 is connected to a water path of the faucet 100, and the water treatment device 300 is used for treating water, such as purifying, heating, or foaming, and delivering the treated water to the faucet 100. The main control unit 400 is connected to the opening degree detecting unit 30 and the water treatment device 300 of the faucet 100 to receive sensing information representing the opening degree of the valve cartridge from the opening degree detecting unit 30 and control the water treatment device according to the sensing information. Specifically, the angle sensor 34 is fixed on a PCB, and the PCB is electrically connected to the main control device 400 through a lead and transmits signals.

In one embodiment, as shown in fig. 12, the water treatment apparatus 200 may be a water purifier 201, and a water treatment apparatus 300 of the water purifier 201 includes a water purification apparatus 301 and a water pump 302. The water purification apparatus 301 is communicated with a water path of the faucet 100, and the water pump 302 is disposed in the water path between the water purification apparatus 301 and the faucet 100.

In the related art, when a mechanical faucet is used in a water purifier, the water outlet of the water purifier is generally controlled by the faucet and a high-pressure switch. When the faucet is closed, the water pump pumps water to increase the pressure in the water channel, when the high pressure value of the high-pressure switch is reached, the high-pressure switch acts, the main control system detects the action information of the high-pressure switch to stop the water pump to work, and when the water pump stops working, the water channel still keeps larger pressure. When the water faucet is opened, the water faucet starts to discharge water, the initial water yield is high, the high-pressure switch acts again when the pressure in the water path is released and reaches the low pressure value of the high-pressure switch, the main control device detects the action information of the high-pressure switch, the water pump is started to work, water discharge is supplemented, and the water purifier system is controlled always according to the mode until the water faucet is closed again, so that the normal water discharge is guaranteed.

However, the process from the beginning of water outlet to the detection of the decrease of the pressure of the waterway to start the water pump to supplement the water outlet is delayed, so that the water outlet fluctuates from large to small and then tends to be stable. The instability of the effluent can greatly affect the use experience of users.

In the water purifier 201 of this embodiment, the opening detection device 30 detects the magnetic field rotation angle information representing the current opening of the valve element 20, and outputs the sensing voltage corresponding to the magnetic field rotation angle to the main control device 400, and the main control device 400 converts the sensing voltage into the opening of the valve element 20 and sends a control signal corresponding to the opening to the water pump 302, thereby controlling the operation of the water pump 302. For example, when the faucet 100 is turned off, the main control device 400 obtains the opening degree of the valve element 20 as 0 according to the hall voltage, and the main control device 400 sends a control signal for stopping water supply to the water pump 302, so as to control the water pump 302 to stop water supply. When the faucet 100 is opened, the main control device 400 outputs a corresponding control signal to the water pump 302 according to the opening degree value of the valve cartridge 20 obtained at this time, and the water pump 302 provides water treated by the water purification device 301 to the faucet 100 according to the control signal, and the water supply amount corresponds to the opening degree of the valve cartridge 20 at this time.

In this embodiment, the water supply amount of the water pump 302 is directly determined by the opening of the valve element 20, rather than the pressure in the water path, so that the water output amount of the faucet 100 can be controlled more immediately, and the situations of delayed reaction of the water pump and short stop of the water output can be avoided.

In another embodiment, the main control device 400 may also monitor the time that the valve element 20 is continuously at a certain opening value, and when the time exceeds a preset time, the main control device 400 sends a control signal for stopping water supply to the water pump 302, so as to control the water pump 302 to stop water supply. When the time that the valve core 20 is continuously at a certain opening value exceeds the preset time, it indicates that no one is currently using the faucet 100, and therefore, the main control device 400 automatically controls the water pump 302 to stop supplying water to avoid waste of water.

In one embodiment, the water processor 200 may be a water heater 202, and as shown in fig. 13, the water processing device 300 of the embodiment is a heating device 303, and the heating device 303 is communicated with a water path of the water faucet 100. When a user adjusts the valve core 20 to adjust the water output of the faucet, the opening detection device 30 detects the magnetic field rotation angle information representing the current opening of the valve core 20 and outputs a sensing voltage corresponding to the magnetic field rotation angle information to the main control device 400, the main control device 400 converts the sensing voltage into the opening of the valve core 20 and outputs a control signal to the heating device 303 according to the opening, so as to control the heating power of the heating device 303, and ensure that the water temperature is kept stable after the water output changes. In other embodiments, the main control device 400 may also send a control signal to the heating device 303 according to the opening degree of the valve element 20 to adjust the temperature of the water.

In one embodiment, the water treatment apparatus 200 may be a bubbling water machine 203, and as shown in fig. 14, the water treatment apparatus 300 of the present embodiment is an air supply apparatus 304. The air supply 304 is in communication with the water circuit of the faucet 100. When a user adjusts the valve core 20 to adjust the water output of the faucet 100, the opening detection device 30 detects the magnetic field rotation angle information representing the current opening of the valve core 20 and outputs a sensing voltage corresponding to the magnetic field rotation angle information to the main control device 400, the main control device 400 converts the sensing voltage into the opening of the valve core 20 and outputs a control signal to the air supply device 303 according to the opening, so as to control the air supply amount of the air supply device 303, and ensure that the concentration of the soda water is kept stable after the water output of the faucet 100 changes. In other embodiments, the main control device 400 may also send a control signal to the air supply device 304 according to the opening degree of the valve element 20 to adjust the concentration of the soda water.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
