As shown in fig. 4, 5, 6, 7 and with reference to fig. 2 and 3. For the sake of compact structure, the driving unit 2 and the triggering unit 3 are integrally designed to form the driving controller 6, and the components of the driving unit 2 and the triggering unit 3 are disposed in a housing part 630 of the controller 6, and the housing part 630 includes an upper housing 610 and a lower housing 620.

In this embodiment, the energy storage member is specifically a return torsion spring 221, and the return torsion spring 221 is disposed coaxially with the driving shaft 211. One end of the reset torsion spring 221 is directly or indirectly abutted and matched with the lower shell 620, the other end of the reset torsion spring 221 is directly or indirectly connected with the driving shaft 211, when the linkage rod 212 drives the driving shaft 211 to rotate from the closed valve position to the open valve position, the reset torsion spring 221 is driven to rotate so as to generate a spring torsion, and the spring torsion is used for providing power energy storage for the driving shaft 211 to subsequently rotate in the opposite direction, namely, the reset torsion spring 221 can drive the driving shaft 211 to displace so as to close the valve port 115. Of course, the restoring torsion spring 221 can also be indirectly connected with the driving shaft 211, such as the linkage rod 212 or the limiting plate 231, with the same effect.

The trigger unit 3 includes a signal processing part 310, an electric part 320, an execution part 330, and an alarm part 340.

The signal processing unit 310 includes a circuit board 311, the circuit board 311 is inserted into a side portion of the lower case 620, and the circuit board 311 is powered by a power supply battery 312 disposed in a battery compartment 622 of the lower case 620. A control circuit is included on the circuit board 311. The detection signal input terminal 3111 of the control circuit is electrically connected to the signal lead-out member 411 of the detection unit 410 to detect whether or not an abnormality occurs in a specific environment of the flow path system.

The electric unit 320 includes a micro motor 321, and the actuator 330 includes a decelerator 331 and a stopper rod 332. The lower housing 620 defines a vertically disposed cavity 623, and a radially disposed partition 6231 divides the cavity 623 into an upper cavity 6232 and a lower cavity 6233. The motor 321 and the decelerator 331 are integrally provided in the upper chamber 6232 and supported by the partition 6231, and the output shaft 3311 of the decelerator 331 passes through the notch 6234 in the middle of the partition 6231.

The upper case 610 is provided with a concave or convex formed restriction portion 611 at a position corresponding to the receiving chamber 623 of the lower case 620. After the upper housing 610 and the lower housing 620 are assembled, the limiting part 611 can limit the rotation or movement of the motor 321, and can further press the motor 321 to be fixed, so that the structure is compact.

Fig. 10 is a schematic structural view of the detection unit of the flow path control device.

As shown in fig. 10. The detecting unit 4 includes a detecting part 410, and the detecting part 410 is electrically connected to the detecting signal input terminal 3111 of the circuit board 311 through a signal leading-out part (wire harness) 411.

Specifically, the detecting component 410 is disposed in a position of the flow path system where the environment needs to be detected, such as a bottom plate 413 of the water heater, and the detecting component 410 includes two electrodes 412, and the electrodes 412 have a certain gap from the bottom of the bottom plate 413. When the electric signal of the detection member 410 is a normal electric signal, the two electrodes 412 are not conducted, and the lead-out member (wire harness) 411 is not conducted; when the water heater has abnormal water leakage, the bottom plate 413 accumulates water, when the height of the water exceeds the height of the two electrodes 412, the two electrodes 412 are conducted, the leading-out piece (wire harness) 411 is electrified, and the electric signal of the detection component 410 is transmitted to the signal processing component 310 as an abnormal electric signal.

Fig. 8 and 9 are bottom views of the flow path control device in a first position and a second position, respectively.

As shown in fig. 8 and 9 in conjunction with fig. 6. In a normal state (see fig. 8) in which the valve unit 1 is opened, when the detection signal input terminal 3111 is the "normal electric signal", the stop lever 332 extends out of the mounting hole 6235 (the stop lever 332 is at the first position), and the lower end 3325 abuts against the first limiting portion 2121 of the linkage lever 212 to limit the displacement of the linkage lever 212. In this state, the restoring torsion spring 221 has a spring torsion (power) that rotates the linkage rod 212 in the clockwise (valve-closing) direction, but the stop lever 332 limits the rotation of the linkage rod 212, i.e., limits the restoring torsion spring 221 from releasing power; when the system is in abnormal water leakage, the leading-out part (wire harness) 411 of the detecting part 410 is powered on, and the detecting signal input end 3111 is an abnormal electrical signal, the signal processing part 310 triggers the motor 321 to rotate, the motor 321 drives the speed reducer 331 to decelerate, the output shaft 3311 of the speed reducer 331 rotates to drive the stop rod 332 to axially displace a certain distance towards the direction in the housing (the stop rod 332 is at the second position), at this time, the lower end 3325 of the stop rod 332 is disengaged from the linkage rod 212, under the action of the spring torsion of the reset torsion spring 221, the reset torsion spring 221 drives the linkage rod 212 to rotate towards the clockwise (valve closing) direction, so that the valve unit 1 is in a valve closing state, and at this time, the spring torsion (power) is released (as shown in fig. 9).

When the system fault is cleared, the linkage rod 212 is manually operated to rotate in the counterclockwise direction (valve opening direction), and the reset key (serving as the first reset key 313 in this mode) is pressed at the same time, so that the starting motor 321 rotates reversely, and the stop rod 332 is axially displaced outward of the housing to return to the first position (see fig. 9). Meanwhile, during the rotation of the linkage rod 212 in the counterclockwise direction (opening the valve), the restoring torsion spring 221 is twisted to restore the torsion (power) of the spring. The control process can avoid the influence of abnormal water leakage on the system in time.

The technical scheme has the beneficial effects that the driving unit and the triggering unit are arranged on the driving controller 6, the miniature motor starting stop piece is driven to move through the self-contained power supply battery (the kinetic energy requirement is relatively small), the reserved power of the driving unit is utilized, the valve closing in an abnormal state (the kinetic energy requirement is relatively large) is realized by the starting valve device, the driving controller 6 can maintain the environment monitoring, the valve can be driven to be closed under the abnormal condition, the external power is not required to be accessed, the structure is compact, and the driving controller is suitable for the monitoring requirements of various environments.

As a further extension of the above technical solution, through the program setting of the signal processing component 310, when the system has an abnormal water leakage situation, after the motor 321 rotates, the output shaft 3311 of the speed reducer 331 rotates to drive the stopping rod 332 to axially displace a certain distance toward the inside of the housing (the stopping rod 332 is at the second position), so that the lower end 3325 of the stopping rod 332 is disengaged from the linkage rod 212, and the linkage rod 212 rotates clockwise (close the valve). After a predetermined time interval, the motor 321 is rotated in a reverse direction to axially displace the stopper rod 332 outward of the housing back to the first position (see fig. 9). The advantage of the program starting process is that if the linkage rod 212 is operated to rotate in a counterclockwise direction (valve opening) after the valve is closed due to an abnormal condition, the second limiting portion 2122 on the linkage rod 212 can interfere with the stop rod 332 to limit the rotation of the linkage rod 212. It is possible to prevent unexpected malfunction before accident handling.

In this mode, after the system fault is cleared, the reset button (serving as the second reset key 314 in this mode) can be pressed to activate the motor 321 to drive the stop rod 332 to axially move to the second position in the housing direction, and at the same time, after the manual operation linkage rod 212 rotates in the counterclockwise (valve opening) direction, the second reset key 314 is released, and the activation motor 321 drives the stop rod 332 to axially move back to the first position in the direction away from the housing direction (as shown in fig. 9).

As a further extension of the above technical solution, the triggering unit 3 further comprises an alarm component 340. As a specific embodiment, the alarm unit 340 may include an audible buzzer 341 and a photoelectric warning light 342. When the system has a water leakage abnormal condition and the leading-out part (wire harness) 411 of the detection part 410 is electrified, the signal processing part 310 triggers the sound buzzer 341 to sound and triggers the photoelectric alarm lamp 342 to flicker so as to remind the staff to process, and the staff can press the cancel key 343 to reset the sound buzzer 341 and the photoelectric alarm lamp 342 while processing.

FIG. 11 is a bottom view of another flow control device of the present invention in a first position.

As shown in fig. 11. As a further extension of the above technical solution, the stop rod 332A may be designed to have a structure with a partial rotating portion, and the output shaft 3311 of the reducer 331 directly drives the stop rod 332A to rotate, and can also be implemented at the first position/the second position to limit/not limit different functions of the linkage rod 212A. And will not be described in detail herein.

The above description is only of the preferred embodiments of the present invention, and it should be noted that, for those skilled in the art, several modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
