[0027] As Figs. 1-2 shown, the present application provides an air filter regeneration control method, applied to an air filter regeneration system, the air filter regeneration system comprising: a first pressure sensor 500 arranged at an air filter air outlet 104, a control module 700 connected with the pressure sensor, a regeneration gear switch 800 connected with the control module 700, and a regeneration purge device connected with the control module 700 and communicating with the inside of the air filter 100, the control module 700 is also connected with an engine 600; the air filter regeneration control method comprises:

[0029] S2acquire engine state, regeneration gear switch state and the regeneration purge device state;

[0030] S3the control module 700 determines whether the air filter 100 is in a state requiring regeneration according to the negative pressure value at the air filter outlet 104;

[0031] S4when the air filter 100 is in a state requiring regeneration, the regeneration purge device is opened or closed according to the regeneration purge device state, the engine state and the regeneration gear switch state.

[0032] Specifically, the maintenance of the air filter 100 can be automatically completed, the function of the filter element 101 can be quickly realized, the intake resistance can be reduced, the power and fuel economy of the engine 600 can be improved, and the user can reduce the burden of taking out the filter element 101 for blowing and regeneration.

[0033] Even when the air filter 100 is in a state requiring regeneration, the control module 700 determines whether to implement regeneration according to the regeneration purge device state, the engine state and the regeneration gear switch state. Combined with the purge device state, the effect of air filter 100 regeneration can be ensured, combined with the engine state, the vehicle can not be regenerated during driving to ensure the driving safety of the vehicle; the setting of the regeneration gear switch 800 makes whether the vehicle is regenerated mainly in the hands of the driver, and the vehicle can not be regenerated under inappropriate environmental conditions.

[0034] As an optional implementation, the control module 700 determines whether the air filter 100 is in a state requiring regeneration according to the negative pressure value at the air filter outlet 104, including: if the negative pressure value at the air filter outlet 104 does not reach the preset outlet pressure value, the air filter 100 is in a state not requiring regeneration.

[0035] As an optional implementation, the control module 700 determines whether the air filter 100 is in a state requiring regeneration according to the negative pressure value at the air filter outlet 104, including: if the negative pressure value at the air filter outlet 104 reaches the preset outlet pressure value, the air filter 100 is in a state requiring regeneration.

[0036] The size relationship between the negative pressure value at the air filter outlet 104 and the preset outlet pressure value is used to determine whether the air filter 100 needs to be regenerated, which improves the intelligent degree of air filter regeneration. If the negative pressure value at the air filter outlet 104 is less than the preset outlet pressure value, it indicates that the air filter 100 needs to be blown and regenerated; if the negative pressure value at the air filter outlet 104 is greater than the preset outlet pressure value, it indicates that the air filter 100 does not need to be blown and regenerated.

[0039] Specifically, if the pressure value of the gas storage tank 201 of the regeneration blowing device does not reach the preset pressure value of the gas storage tank 201, it indicates that the gas content in the gas storage tank 201 of the regeneration blowing device is less, and the normal blowing work cannot be performed. By reading the pressure value of the second pressure sensor 202, it is determined whether to blow and regenerate after determining the gas content in the gas storage tank 201. The effect of blowing and regeneration is ensured, and the intelligent degree of blowing and regeneration of the air filter 100 is improved.

[0040] As an optional implementation, it further includes: setting a time period between a regeneration end time and a time when the negative pressure value at the air filter outlet 104 reaches a preset pressure limit as a preset time period; determining the cumulative running time of the engine 600 in the previous preset time period; and determining the state of the filter element 101 of the air filter 100 according to the cumulative running time of the engine 600 in the previous preset time period.

[0042] As an optional implementation, the air filter regeneration system further comprises a vehicle networking module 1000 connected to the control module 700, wherein when the air filter 100 is in a state that does not need to be regenerated, the vehicle networking module 1000 outputs a signal indicating that the air filter 100 is in a good state; when the air filter 100 is in a state that needs to be regenerated, the vehicle networking module 1000 outputs a signal indicating that the air filter 100 needs to be regenerated.

[0045] Specifically, as an optional and specific embodiment, air enters the air filter 100 through the air filter inlet 103, and clean air flows out of the air filter outlet 104 after being filtered by the filter element 101. As dust accumulates on the filter element 101, the pressure value at the air filter outlet 104 increases, and the first pressure sensor 500 transmits the negative pressure value to the control module 700. The control module 700 comprehensively considers the working state of the engine 600, the position of the regeneration gear switch 800, and outputs relevant signals to the display module 900 and the vehicle networking module 1000 according to the strategy, and opens the electromagnetic valve 300 to blow off the dust on the filter element 101 with the gas in the gas storage tank 201, so that the filter element 101 meets the use requirements. The control module 700 judges whether the gas pressure in the gas storage tank 201 meets the regeneration of the air filter 100 through the signal input by the second pressure sensor 202. The regeneration gear switch 800 has two gear states of "off" and "regeneration". When the gear switch is in the off gear, even if the filter element 101 needs to be regenerated, only a reminder is output, and the electromagnetic valve 300 is not opened. When the regeneration gear switch 800 is in the regeneration gear, the control module 700 will open the electromagnetic valve 300 to regenerate the filter element 101 by judging that the conditions are met. The control module 700 judges whether the engine 600 is in a running or off state through the speed signal input by the engine 600.

At the same time, the vehicle networking module 1000 outputs a signal that the air filter 100 needs to be regenerated.

[0048] When the regeneration gear switch 800 is in the off state, if the minimum pressure value of the first pressure sensor 500 during the running of the engine 600 < the preset limit value, the cumulative running time of the engine 600 in the previous preset period ≥ the preset limit value, and the pressure of the gas storage tank 201 < the preset value, the display module 900 outputs a signal that the air filter 100 needs to be regenerated and the gas pressure of the gas storage tank 201 is insufficient, and the vehicle networking module 1000 outputs a signal that the air filter 100 needs to be regenerated.
