At this time, the liquid level sensor 12 sends an alarm indication signal to the engine 7.

[0133] When a large amount of accumulated water enters the air intake pipe 2, since the waterproof device 1 is lower than the air intake pipe 2, the accumulated water will flow through the first hose 4 into the waterproof device 1 and be stored in the collection box 143. When the water level in the middle channel reaches the second preset water level, that is, reaches the height of the protection probe 121, the negative electrode probe 123, the protection probe 121 and the engine control module form a closed loop. At this time, the liquid level sensor 12 sends a protection indication signal to the engine 7.

[0134] Further, when it is detected that the water level in the waterproof device 1 reaches the first preset water level, the first pipeline is controlled to be closed, specifically, the control valve 3 is controlled to rotate counterclockwise to close the left pipe opening where the air inlet pipe 2 is connected to the second hose 5; and an alarm prompt is output;

[0135] When it is detected that the water level in the waterproof device 1 reaches the second preset water level, the first pipeline and the second pipeline are controlled to be closed. Specifically, the control valve 3 is controlled to rotate clockwise to close the right side pipe opening where the air intake pipe 2 is connected to the second hose 5. While outputting the alarm prompt, the engine 7 is shut down and the engine 7 is prohibited from starting.

[0136] Specifically, when the liquid level sensor 12 detects that the water level in the waterproof device 1 reaches the first preset water level, an alarm indication signal is sent to the engine control module. After receiving the alarm indication signal, the engine control module controls the closing of the first pipeline, specifically controls the control valve 3 to rotate counterclockwise to close the left pipe opening where the intake pipe 2 and the second hose 5 are connected; and the control instrument outputs an alarm prompt, so as to prompt the driver to drive the vehicle out of the wading area as soon as possible to avoid water damage to the engine 7.

[0137] When the liquid level sensor 12 detects that the water level in the waterproof device 1 reaches the second preset water level, it sends a protection indication signal to the engine control module. After receiving the protection indication signal, the engine control module controls the closing of the first pipeline and the second pipeline, specifically, controls the control valve 3 to rotate clockwise to close the right side pipe opening where the intake pipe 2 is connected to the second hose 5 to cut off the air supply; and, while outputting an alarm prompt, shuts down the engine 7 and prohibits the engine 7 from starting, so as to avoid damage to the engine 7 caused by accumulated water entering the engine 7.

[0138] In an alternative embodiment, Fig. 9 FIG. 1 is a flowchart of an engine waterproof control method provided by this embodiment, referring to FIG. Fig. 9 :

[0139] During normal driving after the vehicle is started, if the vehicle is in normal working conditions, the vehicle maintains normal driving; if the vehicle enters a wading section or encounters wet and rainy weather, it is determined whether the alarm probe 122 sends an alarm indication signal. If the alarm probe 122 does not send an alarm indication signal, the vehicle maintains normal driving; if the alarm probe 122 sends an alarm indication signal, the control valve 3 rotates counterclockwise, and the left pipe opening at the connection between the intake pipe 2 and the second hose 5 is closed. At the same time, the instrument on the vehicle outputs an alarm prompt. After receiving the alarm prompt, the driver drives the vehicle into a safe area as soon as possible and checks whether the intake system has water ingress;

[0140] Furthermore, it is determined whether the protection probe 121 sends out a protection indication signal. If the protection probe 121 does not send out a protection indication signal, the instrument continues to alarm until the driver drives the vehicle out of the wading section and checks the intake system to eliminate the alarm prompt; if the protection probe 121 sends out a protection indication signal, the control valve 3 rotates clockwise, the right side pipe opening where the intake pipe 2 and the second hose 5 are connected is closed, and the engine 7 is controlled to stop. While the vehicle's instrument outputs an alarm prompt, the engine 7 is prohibited from starting again.

[0141] The embodiment of the present application provides a waterproof device, which includes: an air intake cavity, a liquid level sensor, an exhaust cavity and a drainage component; one end of the air intake cavity is connected to the engine air intake pipeline of the vehicle, and the other end of the air intake cavity is snap-fitted to the exhaust cavity; the liquid level sensor passes through the first end of the shell of the exhaust cavity and the first end of the shell of the air intake cavity in sequence and is snap-fitted to the first end of the shell of the exhaust cavity; the drainage component is arranged at the second end of the shell of the exhaust cavity, and is used to discharge the accumulated water flowing through the drainage component, and the first end of the shell of the exhaust cavity corresponds to the second end of the shell of the exhaust cavity. The present application connects the waterproof device with the engine air intake pipe, so that the air intake pipe can discharge the accumulated water through the waterproof device after water enters, thereby preventing the accumulated water from entering the engine and causing the engine to stall or be damaged, which is beneficial to the safe driving of the driver and passengers.
