[0072] Referring toFigure 3 The laser sensor used in the embodiment mainly comprises a laser emitter 161 and a light signal receiver 162, and the laser emitter 161 and the light signal receiver 162 are closely connected and arranged in parallel. The laser emitter 161 is provided with a laser emitting port 1611 in the middle thereof. The light signal receiver 162 is provided with a light receiving port 1621 in the middle thereof.

[0073] Referring to FIG. 4(a), when low-pressure gas enters from the gas inlet port 12, the gas inlet valve spring 143 is contracted under the action of the internal and external pressure difference, the gas inlet valve disc 144 is opened, and a certain gap is formed between the gas inlet valve disc 144 and the gas inlet valve seat 141. The gas enters from the gas inlet valve lift limiter passage 1422 and then enters the cylinder 31 from the gas inlet passage 22;

[0074] Referring to FIG. 4(b), when high-pressure gas enters from the gas outlet passage 23, the gas outlet valve spring 153 is contracted under the action of the internal and external pressure difference, the gas outlet valve disc 154 is opened, and a certain gap is formed between the gas outlet valve disc 154 and the gas outlet valve seat 151. The gas flows out from the gas outlet valve lift limiter passage 1522 and then flows out of the cylinder 31 along the gas outlet port 13;

[0075] When the gas inlet valve assembly 14 and the gas outlet valve assembly 15 are in the closed state, the light signal receiver 162 at the top of the light receiving port 1621 cannot receive light after the laser emitter 161 emits laser light from the laser emitting port 1611. The signal is transmitted out through the signal transmission passage 17 and then transmitted to the rear controller for analysis.

[0076] When the gas inlet valve assembly 14 and the gas outlet valve assembly 15 are in the open state, the light signal receiver 162 at the top of the light receiving port 1621 can receive the reflected light after the laser emitter 161 emits laser light from the laser emitting port 1611. The signal is also transmitted out through the signal transmission passage 17 and then transmitted to the rear controller for analysis.

[0077] Referring to FIG. 4(c), when the gas inlet valve assembly 14 and the gas outlet valve assembly 15 are in the open state, the light signal receiver 162 at the top of the light receiving port 1621 can receive the reflected light after the laser emitter 161 emits laser light from the laser emitting port 1611. The signal is also transmitted out through the signal transmission passage 17 and then transmitted to the rear controller for analysis. Figure 5 The laser sensor 16 on the gas inlet valve assembly 14 and the gas outlet valve assembly 15 judges whether the gas inlet valve disc 144 and the gas outlet valve disc 154 are in the process of opening or closing by sensing the state change of the light, so as to judge the working state of the gas valve and transmit the signal to the controller to control the opening and closing of the nozzle.

[0078] Taking one working process of the cylinder as an example:

[0079] When the compressor is in the expansion stage, the gas inlet valve disc 144 and the gas outlet valve disc 154 are both closed, and the light signal receiver 162 is in a non-light sensing state. Therefore, the command of “maintaining the current state” is output to the controller, and the state of the nozzle 25 is closed.

[0080] When the low-pressure gas enters the cylinder 31, the compressor enters the suction stage, the intake valve disc 144 opens, the light signal receiver 162 changes from the non-photosensitive state to the photosensitive state, and then the laser sensor 16 judges that the cylinder 31 enters the suction stage, and thus outputs the command of “maintain the current state” to the controller, so that the state of the nozzle 25 does not change;

[0081] When the suction ends, the intake valve disc 144 closes, and the light signal receiver 162 changes from the photosensitive state to the non-photosensitive state, and then the laser sensor 16 judges that the suction process in the cylinder 31 ends and enters the compression process, and thus outputs the command of “nozzle open” to the controller, so that the nozzle 25 opens and sprays the ion liquid spray 26 into the cylinder 31;

[0082] When the exhaust starts, the exhaust valve disc 154 opens, and the light signal receiver 162 changes from the non-photosensitive state to the photosensitive state, and then the laser sensor 16 judges that the compression process in the cylinder 31 ends and starts the exhaust, and thus outputs the command of “nozzle close” to the controller, so that the nozzle 25 closes and no longer sprays;

[0083] When the exhaust process ends, the exhaust valve disc 154 closes, and the light signal receiver 162 changes from the photosensitive state to the non-photosensitive state, and then the laser sensor 16 judges that the exhaust process in the cylinder 31 ends and is about to start the suction, and thus outputs the command of “maintain the current state” to the controller, so that the nozzle 25 still maintains the closed state until the next intake valve end laser sensor 16 outputs the command of “nozzle open”, and then the nozzle 25 opens again.

[0084] Since the four actions of the opening of the intake valve disc 144, the closing of the intake valve disc 144, the opening of the exhaust valve disc 154, and the closing of the exhaust valve disc 154 occur in sequence in one working process, and the laser sensor 16 only outputs the signal when the photosensitive state changes, the control signal of the nozzle does not overlap and interfere.

[0085] In summary, the present application monitors the opening and closing states of the gas valve through the light signal, accurately judges the working process in the cylinder, ensures that the spray is sprayed into the cylinder through the nozzle during the working process of the gas compression, reduces the temperature of the gas, and supplements the ion liquid lost in the cylinder.
