[0045] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. The following describes various embodiments of the present invention in detail in conjunction with the drawings.

[0046] Example 1

[0047] See also Figures 1 to 13 The present invention preferably provides a technical solution: a mechanical constant heat control valve, comprising: a valve tube 111, a liquid inlet 112 and a liquid outlet 113 arranged before and after the valve tube 111; and a valve body arranged in the valve tube 111; the valve body comprises a frame 211, and a first blade assembly and a second blade assembly installed in the frame 211 and arranged in front and behind along the water flow direction; a first coil 212, a battery 214 and a second coil 215 are sequentially arranged on the frame 211; the first blade assembly can rotate relative to the second blade assembly, and a first magnet 313 is arranged at the end of the first blade assembly and placed in the package of the first coil 212. Under the action of water flow, the first blade assembly is used for energy storage of the battery 214 under the joint action of the first coil 212 and the first magnet 313; and a second magnet 412 is arranged at the end of the second blade assembly and placed in the package of the second coil 215. The battery 214 outputs current to the second coil 215, and the second blade assembly is actively controlled to rotate under the joint action of the second coil 215 and the second magnet 412, thereby controlling and adjusting the liquid flow rate.

[0048] In this design, the first blade assembly and the second blade assembly are arranged front and back along the water flow direction in the frame 211, such as Figure 1 , 2 , 4 and 5, the first blade assembly can rotate freely and is located at the front end of the second blade assembly;

[0049] In the first process, the energy storage process of the first blade assembly, under the action of the water flow, it drives the first magnet 313 to rotate in the area of ​​the first coil 212, and at this time, similar to the principle of a generator, the mechanical energy is converted into electrical energy and stored in the battery 214;

[0050] In the second process, the second blade assembly actively adjusts the flow rate. The battery 214 provides current to the second coil 215. Under the action of a plurality of second magnets 412, it operates in a manner similar to that of an engine. The second coil 215 and the battery 214 work together to drive the second blade assembly to rotate counterclockwise or clockwise as a whole, so as to promote or inhibit the flow rate.

[0051] Example 2

[0052] As another embodiment of the present invention, the first blade assembly includes a sleeve 316, and a first blade 311 arranged in an annular shape on the outer wall of the sleeve 316, the first blade 311 is inclined at a certain angle to the sleeve 316, and the first magnet 313 is detachably installed on the radial outer end of the first blade 311; the frame 211 is provided with a plurality of grooves 220 on the inner wall near the first blade assembly, each groove 220 is provided with an annularly distributed stopper 221, each stopper 221 is in an "inverted triangle" structure, and a plurality of guide grooves 312 are provided on each first blade 311, and the end of each guide groove 312 converges at the groove 220.

[0053] In this embodiment, a design structure of a first blade assembly is further provided, which is as follows: Figure 3 , 4 As shown in FIG. 6 , since the first blade assembly can rotate freely, specifically, it is composed of a plurality of first blades 311 arranged on the shaft sleeve 316 at a certain inclination angle, and a plurality of guide grooves 312 are opened on the first blades 311, and the guide grooves 312 are arc-shaped and converge at the groove 220 at their ends, and a plurality of stoppers 221 in an "inverted triangle" structure are arranged inside the groove 220, as shown in FIG. Figure 6 As shown, when the liquid is transported to the groove 220 where the frame 211 is located through the guiding effect of the guide groove 312, when the water flow acts on the block 221, it will convey an impact force in the opposite direction to the liquid, and finally act on the corresponding first blade 311 through the reverse impact, thereby accelerating the rotation of the entire first blade assembly, and through the first magnet 313 at the end of the first blade 311, under the joint action of the first magnet 313 and the first coil 212, electrical energy is stored and enters the battery 214.

[0054] Example 3

[0055] As other embodiments of the present invention, the second blade assembly includes a magnetic flow channel assembly arranged at the rear end of the frame 211, the magnetic flow channel assembly extends to the center position of the frame 211 and is vertically provided with a rotatable assembly tube 911, the assembly tube 911 is provided with an adjustment bracket assembly near the front section of the magnetic flow channel assembly, the adjustment bracket assembly is provided with a second blade 411 distributed in an annular manner and at a certain angle, the second magnet 412 is detachably installed at the radial outer end of the second blade 411, and the magnetic flow channel assembly is used to control the deflection of the adjustment bracket assembly and thereby change the inclination angle of the second blade 411; the sleeve 316 is rotatably installed at the rear section of the assembly tube 911 away from the magnetic flow channel assembly.

[0056] In this embodiment, by further providing a second blade assembly, this function can be used to actively adjust the flow rate of the liquid. It has two modes: speed-up and speed-down:

[0057] The deceleration process is to increase resistance to the passing liquid, which acts as a reverse inhibition to reduce the flow rate of the liquid;

[0058] The speed-increasing process is to add a momentum to the liquid, which acts as a positive promotion to increase its flow rate.

[0059] There are two variations in the design of the second blade assembly:

[0060] like Figure 4 and 13 As shown, when water flows from the first blade assembly to the second blade assembly, as shown in Fig.13 As shown, when the water flow from the first blade assembly acts laterally on the second blade 411, at this angle, the single second blade 411 tends to rotate clockwise, and the second blade 411 as a whole tends to move counterclockwise; promoting or inhibiting the above two tendencies can increase or decrease the water speed, increase the flow rate, and increase the heat per unit time, while reducing the water speed can reduce the heat per unit time.

[0061] Specifically;

[0062] One is: for a single second blade 411, the water flow generates a force on the second blade 411 to make it produce a clockwise movement trend. At this time, the single second blade 411 is controlled to rotate counterclockwise to suppress the rotation trend of the second blade 411. At this time, the obstruction angle between the water flow and the second blade 411 increases. In order to reduce the flow rate, when the single second blade 411 is controlled to rotate clockwise to promote the rotation trend of the second blade 411, the obstruction angle between the water flow and the second blade 411 decreases. The water will flow more smoothly, reducing resistance and increasing the flow rate.

[0063] The other is: for the overall drive control of the second blade assembly, such as Figure 5 As shown, the battery 214 supplies energy to the second coil 215, and under the joint action of the second coil 215 and the second magnet 412, the motor principle is simulated to drive the second blade 411 to rotate as a whole, as shown in FIG. Figure 4 , 13 As shown, when the second blade 411 rotates counterclockwise as a whole, in order to promote the overall counterclockwise rotation of the above-mentioned second blade assembly, it is equivalent to reducing the resistance to water flow, which has a role in increasing the flow rate. When the second blade 411 rotates clockwise as a whole, in order to inhibit the overall counterclockwise rotation of the above-mentioned second blade assembly, it is equivalent to increasing the resistance to water flow, which has a role in reducing the flow rate.

[0064] Example 4

[0065] As other embodiments of the present invention, the magnetic flow channel assembly includes a first damping control module 711 fixed at the end of the frame 211, the first damping control module 711 is provided with a first connecting electrode 712 at the radial outer end, and a first damping cavity 713 is opened on the inner side of the first damping control module 711, and a second damping control module 811 is assembled with the first damping control module 711, the second damping control module 811 is also provided with a second connecting electrode 812 at the radial outer end, a second damping cavity 813 is opened on the inner side of the second connecting electrode 812, and the bottom of the second damping cavity 813 is connected to the first damping cavity 713 and magnetic fluid is respectively arranged therein.

[0066] Furthermore, the adjusting bracket assembly is fixed to a connecting shaft 421 at the bottom of the second blade 411, the bottom end of the connecting shaft 421 passes through the assembly hole 912 opened on the assembly tube 911 and is fixed with a transmission member 420, and the transmission member 420 is provided with two groups of transmission grooves 4201; and a first damping shaft 511 rotating on the inner side of the assembly tube 911, the first damping shaft 511 is sequentially provided with a through groove 514, a first protrusion 513, and a first damping plate 512, the first protrusion 513 is limited in one of the transmission grooves 4201, and the first damping plate 512 is placed in the first damping cavity 713. When the first connecting electrode 712 is supplied with current, the magnetic fluid in the first damping cavity 713 acts on the first damping plate 512 to control the first damping shaft 511 where it is located. 1 Braking; A rotatable second damping shaft 611 is provided in the end of the first damping shaft 511 close to the first damping plate 512, and a second protrusion 613 and a second damping plate 612 are sequentially provided on the second damping shaft 611. The second protrusion 613 passes through the through groove 514 and is limited in another transmission groove 4201. The second damping plate 612 is placed in the second damping cavity 813. When the second connecting electrode 812 is supplied with current, the magnetic fluid in the second damping cavity 813 acts on the second damping plate 612 to control the braking of the second damping shaft 611 where it is located. Through the relative braking of the second damping shaft 611 and the first damping shaft 511, the inclination trend of the second blade 411 is controlled under the action of the transmission member 420, thereby promoting or inhibiting the flow rate of the liquid.

[0067] Furthermore, it also includes a sleeve 1011, which is sleeved on the pipe section of the adjusting bracket assembly where the assembly pipe 911 is located. The sleeve 1011 has a polygonal structure and is used to arrange the inclined second blades 411, and a plurality of mounting holes 1012 are opened on the sleeve 1011. The mounting holes 1012 correspond to the assembly holes 912 one by one and are used for the passage of the connecting shaft 421.

[0068] Furthermore, the first connection electrode 712 and the second connection electrode 812 are respectively connected to the battery 214 through wires.

[0069] In this embodiment, a magnetic flow channel assembly and an adjustment bracket assembly are provided for use in combination, which can promote or inhibit the adjustment of the inclination angle of a single second blade 411;

[0070] Specifically, Figure 7 , 8 As shown in FIGS. 9, 10, 11 and 12, the assembly of the magnetic flow channel assembly and the adjusting bracket assembly is to rotate the assembly tube 911. When the second blade assembly is driven to rotate as a whole, the second blade 411 as a whole rotates together with the adjusting bracket assembly and the first damping shaft 511 and the second damping shaft 611 therein;

[0071] like Figure 8 , 9 As shown in FIGS. 10 and 12, the second protrusion 613 on the second damping shaft 611 passes through the through slot 514 and slides within the transmission slot 4201 on the left side, while the first protrusion 513 on the first damping shaft 511 moves within the transmission slot 4201 on the right side, and the connecting shaft 421 is rotatably mounted on the assembly hole 912 where the assembly tube 911 is located. Through the relative rotation trend of the first damping shaft 511 and the second damping shaft 611, the positions of the first protrusion 513 and the second protrusion 613 are changed, thereby driving the second blade 411 where the connecting shaft 421 is located to adjust the inclination angle, such as, in the second When the blade assembly rotates counterclockwise as a whole, if you want to prevent the second blade 411 from rotating clockwise, you need to limit and prevent the first protrusion 513 where the first damping shaft 511 is located from moving, and then give it a counterclockwise movement trend when the second blade 411 rotates clockwise, thereby playing a suppressive role. Similarly, when providing power, control the damping rotation size of the second damping shaft 611 to form a promoting deflection movement trend for the second blade 411. The final effect is that when the water temperature is too high, the water flow rate is reduced to maintain constant heat, and the second blade 411 needs to provide water with a resistance. When the water temperature is too low, the angle is adjusted accordingly to control the size of the water resistance, thereby adjusting the water flow rate;

[0072] The motion states of the first damping shaft 511 and the second damping shaft 611 are controlled, such as Figure 8 , 9 As shown in 10, by the cooperation between the first damping plate 512 at the right end of the first damping shaft 511 and the first damping chamber 713, and the second damping plate 612 and the second damping chamber 813, and by filling the first damping chamber 713 and the second damping chamber 813 with magnetic liquid, when the first connecting electrode 712 and the second connecting electrode 812 are energized, the damping of the magnetic liquid is adjusted by the current, and then the damping degree of the first damping shaft 511 and the second damping shaft 611 is correspondingly controlled, thereby realizing the change of the rotational resistance.

[0073] Furthermore, the battery 214 is annular and covers the outer wall of the second coil 215 . The first coil 212 is connected to the battery 214 and stores electrical energy in the battery 214 . The battery 214 is connected to the second coil 215 and outputs electrical energy to the second coil 215 .

[0074] Example 5

[0075] A control method for a mechanical constant heat control valve is applied to the aforementioned mechanical constant heat control valve, and the control method comprises the following steps:

[0076] S1: Under the action of water flow, through the energy storage process of the first blade assembly, it drives the first magnet 313 to rotate in the first coil 212 area, converting mechanical energy into electrical energy and storing it in the battery 214;

[0077] S2: The battery 214 then provides current to the second coil 215, and under the action of the second magnets 412, the second coil 215 and the battery 214 work together to drive the second blade assembly to rotate counterclockwise or clockwise.

[0078] S3: The inclination angle of the single second blade 411 is further slightly adjusted by using the magnetic flow channel assembly in combination with the adjustment bracket assembly.
