[0023] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Please refer to Figures 1 to 3 An embodiment of the utility model provides a turbine water flow control valve, including a valve seat 1, a valve chamber 2, a turbine 3, a worm 4, a signal generator 5, a signal resonance processing center 6 and a signal transmission line 7. The various components of this embodiment are described in detail below in conjunction with the accompanying drawings.

[0025] like Figures 1 to 3As shown, the valve cavity 2 can be set as a hollow cavity structure with an opening at the top, a water inlet chamber 21 is opened at the bottom of the valve cavity 2, a circular groove 11 is protruded upward at the bottom of the valve seat 1, the opening part of the valve cavity 2 is connected to the bottom of the valve seat 1 and is arranged through the circular groove 11, the worm 4 is rotatably arranged inside the water inlet chamber 21 and the circular groove 11, the turbine 3 is fixedly connected to one end of the worm 4 and is located inside the water inlet chamber 21, and the signal generator 5 is fixedly connected to the other end of the worm 4 and is located in the circular groove 11.

[0026] like Figure 4 As shown, the top of the valve seat 1 can be recessed downward to provide an annular groove 12 that connects to the outer wall of the circular groove 11. The annular groove 12 can be circumferentially arranged around the outer wall of the circular groove 11. The signal resonance processing center 6 is fixedly arranged inside the annular groove 12. The signal transmission line 7 is located outside the valve seat 1. The signal transmission line 7 is electrically connected to the signal resonance processing center 6.

[0027] In this embodiment, the signal generator 5 can be configured as a Hall induction magnetic ring, and the signal resonance processing center 6 can be configured as a double-stage Hall element.

[0028] In specific implementation, water flows through the turbine 3 to generate vortex, causing the turbine 3 to rotate rapidly and drive the signal generator 5 to rotate synchronously through the worm 4. The signal generator 5 can continuously convert the water flow power into an electrical signal.

[0029] Among them, the Hall induction magnetic ring rotates synchronously and rapidly under the drive of the worm 4, and transmits signals through the six-pole magnetic induction. The two-stage Hall element senses the magnetic field, cuts the magnetic induction line, and then processes the signal into a pulse signal. The processed pulse signal is transmitted to the control chip on the external mainboard through the signal transmission line 7. The control chip controls the power supply of the external water pump motor according to the received signal.

[0030] like Figure 5 As shown, a plurality of diversion holes 22 may be uniformly arranged on the bottom end surface of the water inlet chamber 21 , and a valve plate 23 is formed between one side of each diversion hole 22 and the inner wall of the water inlet chamber 21 .

[0031] Specifically, two water inlets 24 connected to the water inlet chamber 21 may be respectively opened on the middle outer wall of the valve cavity 2. The arrangement of the diverter hole 22, the valve plate 23 and the water inlet 24 can reduce the resistance of water flow, thereby improving the water inlet efficiency.

[0032] like Figure 6As shown, four connecting blocks 13 connecting the outer walls of the circular groove 11 can be formed on both sides of the inner wall of the annular groove 12, and the connecting blocks 13 correspond to each other in pairs and respectively separate the outer wall of the circular groove 11 from the inner wall of the annular groove 12 to form two accommodating spaces 14 for placing the signal resonance processing center 6, and two limiting protrusions 15 are respectively formed on the two side walls close to the corresponding annular groove 12 in each accommodating space 14.

[0033] Furthermore, the signal resonance processing center 6 can be inserted downward into the accommodating space 14, one side wall of the signal resonance processing center 6 contacts one side wall of the two limit protrusions 15, and the two side edges of the bottom of the signal resonance processing center 6 are respectively engaged with the two side walls of the accommodating space 14.

[0034] Preferably, a dust cover 8 can be fixedly installed on the top surface of the valve seat 1, and the dust cover 8 is arranged above the top surface of the annular groove 12. The dust cover 8 is provided with a through hole 81 for the signal transmission line 7 to pass through, and a plurality of anti-slip grooves 82 are evenly arranged on the outer wall of the dust cover 8.

[0035] Preferably, a dust cover 9 may also be included, which is sleeved on the outer wall of the connection portion between the valve cavity 2 and the valve seat 1 and is located above the water inlet 24 .

[0036] like Figure 7 As shown, the middle outer wall of the valve seat 1 can be provided with an annular convex eave 16 downward, the bottom of the valve seat 1 is provided with a convex table 17, the circular groove 11 is recessed upward in the middle of the convex table 17, and an annular limiting portion 18 is recessed between the convex table 17 and the annular convex eave 16 for the tube wall of the dust cover 9 to be placed.

[0037] The working principle of this embodiment is as follows:

[0038] First, water flows through the water inlet chamber of the valve cavity and enters the turbine to generate eddy currents. The eddy currents make the turbine rotate rapidly, and synchronously drive the signal generator (Hall induction magnetic ring) to rotate through the worm. The rotation of the turbine makes the signal generator continuously transmit signals through the 6-pole magnetic induction. The signal resonance processing center (two-stage Hall element) senses the magnetic field, cuts the magnetic induction line, and then processes the signal into a pulse signal. The processed signal is then transmitted to the control chip on the external motherboard through the signal transmission line. The control chip controls the power supply of the external water pump motor according to the received signal and adjusts the water pump motor as needed, including adjusting the motor speed to control the amount of pumped water, or adjusting the heating element to keep the water temperature constant, which can ensure that even in the case of small water flow, a stable water flow and water temperature can be provided, thereby avoiding the water flow from fluctuating or changing temperature.

[0039] In summary, the utility model can ensure that a stable water flow and water temperature can be provided even in the case of a small water flow, and can provide users with a more comfortable and consistent water flow experience, thereby improving the user experience.

[0040] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
