The No. 5 battery is used for supplying power to the transmitter 19, and the transmitter 19 is used for sending information of the liquid level sensor 20 to the remote control receiver 8.

The traditional exhaust method needs two persons to cooperate with each other, one person continuously steps on a clutch pedal and a brake pedal in a cab, after the person steps on the clutch pedal and the brake pedal, the other person screws on an exhaust screw under a vehicle to deflate, then screws on the exhaust screw, then steps on the clutch pedal and the brake pedal, and then screws on the exhaust screw to deflate, and then screws on the exhaust screw, and the operation is circulated until air in a pipeline is exhausted completely. The traditional operation needs 2 persons to understand the operation, and is time-consuming, labor-consuming and inefficient. Adopt exhaust apparatus, only need operate alone, at first connect the power or connect the air supply, change the vehicle oil storage bowl cover of taking level sensor with vehicle oil storage bowl cover unscrewing, unscrew exhaust screw and insert exhaust screw with the oil outlet hose, press remote controller "row" and start the exhaust promptly, when vehicle oil storage bowl brake fluid level highly reach the requirement after the automatic shutdown exhaust, then screw up exhaust screw can. In addition, traditional exhaust method is from last down to exhaust, still needs the segmentation to exhaust sometimes, arranges the master cylinder upper end earlier and then arranges the master cylinder lower extreme again, and must 2 individual mutually support and need 30 minutes at least just can accomplish, the utility model discloses only need 1 personal operation, be a key formula operation moreover, from bottom to top reverse exhaust, exhaust completion back automatic stop, fool's operation, the shang shou is simple, and exhaust efficiency height only needs about 2 minutes can accomplish.

The utility model discloses there are two kinds of exhaust modes of electronic mode and atmospheric pressure mode. Under electric mode, go up the power clamp and pour brake fluid into in the oil storage tank (usually 2L can), insert the exhaust bolt with the oil outlet hose, unscrew the exhaust bolt, change vehicle oil storage cup lid with level sensor with vehicle oil storage cup lid back-off again, press the exhaust button of remote controller, exhaust apparatus begin the exhaust promptly. When the height of the brake fluid level of the vehicle oil storage cup reaches the standard scale, the exhaust is automatically stopped, and finally the exhaust bolt is screwed. Specifically, after the exhaust button of the remote controller is pressed, the remote control receiver energizes the electric oil pump, the electric oil pump starts pumping oil, and the brake fluid passes through the oil pump and then enters the exhaust bolt through the oil outlet hose. The brake fluid enters the exhaust bolt, then enters the branch pump and the main pump through the pipelines, and finally flows into the vehicle oil storage cup. When the brake fluid level in the oil storage cup reaches the standard scale, the liquid level sensor works, a signal is sent to the remote control receiver to enable the electric oil pump to be powered off to stop pumping oil, and the exhaust bolt is tightened to finish exhaust. The oil pump is at the oily in-process of pump, and the liquid level can be less and less in the oil storage tank, can form pressure differential in the jar with the jar outside, and at this moment oil storage tank lid air vent rubber packing pad can open automatically under the effect of pressure differential ventilates.

Under atmospheric pressure mode, connect the air supply (vehicle gas receiver or air pump all can) with the air supply joint, pour the brake fluid into in the oil storage tank (usually 2L can), insert the exhaust bolt with the oil outlet hose, unscrew the exhaust bolt, change the vehicle oil storage cup lid that has level sensor with vehicle oil storage cup lid back off again, press the exhaust button on the remote controller, exhaust device start the exhaust promptly, when vehicle oil storage cup brake fluid liquid level reach the standard scale after the automatic shutdown exhaust, screw up the exhaust bolt at last can. Specifically, when an air source connector is connected with an air source, compressed air is decompressed by a pressure reducing valve and enters an electronic air valve, the electronic air valve is closed under the condition of no power supply, when an exhaust button of a remote controller is pressed, a remote control receiver supplies power to the electronic air valve, the electronic air valve is opened, the compressed air enters an oil storage tank, and under the action of the internal pressure of the oil storage tank, brake fluid passes through an oil pump and then enters an exhaust bolt through an oil outlet hose. Brake fluid enters the exhaust bolt, then enters the branch pump and the main pump through the pipeline, finally flows into the vehicle oil storage cup, when the brake fluid level in the vehicle oil storage cup reaches the standard scale, the liquid level sensor works, sends a signal to the remote control receiver to enable the electronic air valve to be powered off and stop air intake, so that the air pressure in the oil storage tank is reduced, the brake fluid also stops entering the pipeline, and the exhaust bolt is tightened to finish exhaust.

The above-mentioned embodiments are only for describing the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art without departing from the design spirit of the present invention should fall into the protection scope defined by the claims of the present invention.
