[0037] The following is combined with Figures 1 to 3 , the electric regulating device of the thermal heat recovery system provided in the embodiment of the present application is described in detail through specific embodiments and application scenarios.

[0038] The embodiment of the present invention discloses an electric regulating device for a thermal regenerative system, comprising a housing 100, an automatic blocking mechanism, a flow regulating mechanism, and a pressure regulating mechanism.

[0039] Reference Figure 2 As shown, the shell 100 is arranged between the first connecting pipe 1 and the second connecting pipe 2, and a conical opening 110 is formed on the right inner wall of the shell 100. The shell 110 is connected to the first connecting pipe 1 through the conical opening 110, and the left side of the shell 100 is connected to the second connecting pipe 2. The automatic blocking mechanism is used to block the conical opening 110 connected to the first connecting pipe 1.

[0040] The automatic blocking mechanism includes an elastic reset component and a truncated cone-shaped blocking block 210. The elastic reset component is connected to the truncated cone-shaped blocking block 210. When the air supply is stopped, the truncated cone-shaped blocking block 210 is in a reset state under the elastic force of the elastic reset component, that is, the truncated cone-shaped blocking block 210 blocks the conical opening 110.

[0041] Specifically, in an optional embodiment, the elastic reset assembly includes a moving rod 220, a reset rod 230, and a spring 240. One end of the reset rod 230 is connected with the circular truncated cone plug 210. The moving rod 220 is slidingly sleeved on the reset rod 230. The other end of the reset rod 230 has an anti-disengagement portion for preventing the moving rod 220 from disengaging. The spring 240 is sleeved on the reset rod 230 and located between the moving rod 220 and the circular truncated cone plug 210. The pressure regulating mechanism is connected with the moving rod 220 to adjust and fix the position of the moving rod 220, so that the moving rod 220 cannot move under the elastic force of the spring 240.

[0042] The flow regulating mechanism includes a motor 310, an adjusting screw rod 320, a threaded sleeve 330, a moving block 340, a push rod 350, and a limiting block 360. The output shaft of the motor 310 is connected with the adjusting screw rod 320. The threaded sleeve 330 is arranged on the moving block 340. The adjusting screw rod 320 is in transmission cooperation with the threaded sleeve 330.

[0043] One end of the push rod 350 is in movable contact with the circular truncated cone plug 210 through the limiting block 360. The limiting block 360 limits the circular truncated cone plug 210. The other end of the push rod 350 is connected with the moving block 340.

[0044] The flow regulating mechanism further includes a flow sensor 370, a display screen, and a wireless remote control switch 380. The wireless remote control switch 380 is matched with an external remote controller. The detection head of the flow sensor 370 extends into the second connecting pipe 2. The display screen is electrically connected with the flow sensor 370 to display the flow information detected by the flow sensor 370. The wireless remote control switch 380 is electrically connected with the motor 310. The operation and stop of the motor 310 can be remotely controlled through the external remote controller.

[0045] In this embodiment, the electric regulating device of the heat recovery system further includes a power supply. The motor 310, the flow sensor 370, the display screen, and the wireless remote control switch 380 are all connected with the power supply. The power supply can be a storage battery.

[0046] Based on the above structure, in the initial state, the limiting block 360 limits the circular truncated cone plug 210. The circular truncated cone plug 210 is blocked in the conical opening 110 under the joint action of the spring 240 and the limiting block 360.

[0047] When the gas flow needs to be adjusted, the motor 310 is started by the wireless remote control switch 380, the motor 310 drives the adjusting screw 320 to rotate, the threaded sleeve 330 sleeved on the adjusting screw 320 moves leftwards, the threaded sleeve 330 sequentially drives the limiting block 360 to move leftwards through the moving block 340 and the push rod 350, the limiting position is changed, the gas flow in the first connecting pipe 1 blows and presses the circular truncated cone block 210, the circular truncated cone block 210 moves leftwards along with the limiting block 360 and compresses the spring 240, at this time, a gap is generated between the circular truncated cone block 210 and the conical opening 110, the gas in the first connecting pipe 1 flows into the second connecting pipe 2 through the gap and the shell 100;

[0048] The flow sensor 370 detects the flow size in the second connecting pipe 2: when the gas flow in the second connecting pipe is appropriate, the motor 310 is controlled to stop working, so that the position of the limiting block 360 is fixed, so that the circular truncated cone block 210 is limited to continue to move, so that the size of the gap is limited, at this time, the gas flow in the second connecting pipe 2 remains constant; when the gas flow needs to be increased, the motor 310 is started, so that the limiting block 360 continues to move leftwards, the circular truncated cone block 210 moves leftwards under the action of the gas flow, and then the gap gradually increases, and then the gas flow increases; conversely, when the gas flow needs to be reduced, the motor 310 is started, so that the output shaft of the motor 310 reversely rotates, so that the limiting block 360 changes to move rightwards and pushes the circular truncated cone block 210, so that the gap is reduced, and then the gas flow is reduced.

[0049] When the gas supply is stopped, the action force of the gas flow on the circular truncated cone block 2 disappears, at this time, the spring 240 resets and pushes the circular truncated cone block 210 to block the conical opening 110.

[0052] The pressure regulating positioning rod 420 comprises a connecting portion 4210 and a sleeve joint portion 4220, the sleeve joint portion 4220 is connected with the connecting portion 4210 to make the pressure regulating positioning rod 420 L-shaped, the connecting portion 4210 penetrates into the shell 100 and is connected and fixed with the moving rod 220, the sleeve joint portion 4220 is provided with a threaded hole, and the sleeve joint portion 4220 is sleeved on the pressure regulating screw rod 410 through the threaded hole.

[0053] Based on the above structure, when the spring 240 is in elastic fatigue after long-time use, the elastic force needs to be adjusted, the pressure regulating screw rod 410 is rotated, the moving rod 220 is moved to the right to compress the spring 240, the initial compression state of the spring 240 can be changed, the part of the elastic force caused by the elastic fatigue is offset, and it is ensured that the circular truncated cone-shaped plug 210 can stably block the conical opening 110 of the shell 100.
