In addition, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0041] according to Figure 1 and Figure 2 As shown, the air tank 44 is arranged on the bracket 52, the pre-filter is installed on the support frame 50, the pre-filter includes a shell 10, a filter element 20, an outer honeycomb body 30, an inner honeycomb body 32, a pipeline 42 and a power unit 40, the outer honeycomb body 30 and the inner honeycomb body 32 are both installed in the accommodating cavity in the filter element 20, the air tank 44 is connected to the pre-filter through the pipeline 42, and the outer honeycomb body 30 is driven to rotate by the power unit 40.

[0042] according to Figure 3 As shown, the outer honeycomb body 30 and the inner honeycomb body 32 are provided with a first through hole 34 and a second through hole 36. During the rotation of the outer honeycomb body 30, three situations may occur, namely, the first through hole 34 and the second through hole 36 completely overlap, the first through hole 34 and the second through hole 36 are staggered, and the second through hole 36 is completely shielded by the outer honeycomb body 30.

[0043] according to Figure 4 and Figure 5 As shown in the figure, in an application scenario, the control logic of the filtering system is:

[0044] Step 1: Use the air filter sensor to determine the air resistance. If the resistance is greater than a certain threshold,

[0045] The reminder unit 70 installed in the cab sounds;

[0046] Step 2: After the operator selects to stop the machine, the prompt unit 70 becomes silent, the controller sends a valve body opening signal, the working light 60 lights up, and the air cylinder sprays air;

[0047] Step 3: At the same time, the controller instructs the servo motor to rotate at a preset target speed, driving the outer honeycomb body 30 to rotate;

[0048] Step 4: If the motor rotation time is equal to the preset time, the motor stops rotating, and the outer honeycomb body 30 returns to the starting position, and the holes of the inner and outer honeycomb bodies 30 overlap;

[0049] Step 5: If the power unit 40 stops for a predetermined time, the above rotation and stop process of the power unit is started again in a cycle;

[0050] Step 6: When the number of cycles is equal to the preset number, the working light 60 is turned off, the valve body is closed, the gas storage tank 44 is cut off, and the back-blowing resonance dust removal work is stopped.

[0051] according to Figure 6 As shown, the prompt unit 70 is installed in the cab. When the air resistance meets the threshold, the prompt unit 70 will issue a prompt to select whether to proceed to the next step.

[0052] According to the first aspect of the present invention, a filtering system is provided, comprising: a shell 10, a filter element 20, an outer honeycomb body 30, an inner honeycomb body 32, a power unit 40, an air storage tank 44 and a pipeline 42; a accommodating chamber with one side open is formed inside the shell 10; the filter element 20 is arranged in the accommodating chamber; the outer honeycomb body 30 is sleeved on the outside of the inner honeycomb body 32, and the outer honeycomb body 30 and the inner honeycomb body 32 are both arranged inside the filter element 20; the power unit 40 is arranged at the end of the accommodating chamber away from the opening, and is connected to the outer honeycomb body 30, for driving the outer honeycomb body 30 to rotate; one end of the pipeline 42 is connected to the air storage tank 44, and the other end of the pipeline 42 extends into the inner honeycomb body 32, for transporting a medium to the inner honeycomb body 32.

[0053] Specifically, air and fuel explode in the cylinders of a car to generate power. Today's air environment is harsh, and if the air contains impurities such as dust, it can cause varying degrees of damage to the cylinders. Therefore, various types of pre-filters are installed in cars to filter the air, but most of them suffer from issues such as high air resistance, poor filtering effects, and inability to perform deep dust removal. This application provides inner and outer honeycomb bodies 30, with an air storage tank 44 delivering air to the inner and outer honeycomb bodies 30 via a pipe 42. The power unit 40 provides power to drive the outer honeycomb body 30 to rotate. The temporary overlap and shielding between the holes of the inner and outer honeycomb bodies 30 achieve intermittent air blowing, causing the filter element 20 to resonate and shake off dust. Furthermore, the long-term overlap between the holes of the inner and outer honeycomb bodies 30 is controlled to achieve continuous air blowing, thereby achieving deep dust removal.

[0054] It can be understood that the honeycomb body is a multi-porous structure in the art.

[0055] In a possible implementation, the power unit 40 may be a motor.

[0056] In a possible implementation, the power unit 40 may be a servo motor.

[0057] In a possible implementation, the power unit 40 may be a stepping motor.

[0058] According to one embodiment of the present invention, a plurality of first through holes 34 are evenly distributed on the outer honeycomb body 30, and a plurality of second through holes 36 are evenly distributed on the inner honeycomb body 32; the outer honeycomb body 30 and the inner honeycomb body 32 include: a first state and a second state; in the first state, the first through holes 34 and the second through holes 36 are arranged in a one-to-one correspondence and overlap; in the second state, the first through holes 34 and the second through holes 36 are arranged in an interlaced manner; wherein the power unit 40 drives the outer honeycomb body 30 to rotate, thereby realizing the switching of the outer honeycomb body 30 and the inner honeycomb body 32 between the first state and the second state.

[0059] Specifically, the inner and outer honeycomb bodies 30 have a first state and a second state. In the first state, the first through hole 34 and the second through hole 36 are arranged in a one-to-one correspondence and overlap, and the gas in the gas tank 44 can pass through the first through hole 34 and the second through hole 36 smoothly; in the second state, the outer honeycomb body 30 rotates a certain angle, and the first through hole 34 and the second through hole 36 are staggered with each other, and only part of the gas in the first state can pass through the first through hole 34 and the second through hole 36; the first state and the second state are switched continuously, and the temporary overlap and shielding between the first through hole and the second through hole of the inner and outer honeycomb bodies realize intermittent blowing, causing the filter element 20 to resonate and shake off dust.

[0060] For example, the number of transverse holes in a single layer of the outer honeycomb body 30 is 4, and the number of transverse holes in a single layer of the inner honeycomb body 32 is 1. When the motor rotates one circle, the number of overlaps between the inner and outer holes is 4 times, that is, the injection frequency per rotation is 4.

[0061] In possible ways, such as Figure 3 As shown, due to the rotation of the outer honeycomb body, the first through hole and the second through hole switch back and forth between three states: complete overlap, partial overlap and complete shielding. At this time, the gas passes through the first through hole and the second through hole at a pulsed frequency to impact the filter element, causing the filter element to resonate and then shake off the dust on the filter element.

[0062] In a possible implementation, the number of the first through holes 34 and the second through holes 36 on the inner and outer honeycomb bodies 30 can be adaptively adjusted according to actual needs.

[0063] In a possible embodiment, the long-term overlap between the holes of the inner and outer honeycomb bodies 30 can be controlled to achieve continuous air blowing, thereby achieving deep dust cleaning.

[0064] According to an embodiment of the present invention, the device further includes: a first sensor 12 , which is disposed at one end of the accommodating cavity close to the power unit 40 and is used to detect the rotation parameters of the outer honeycomb body 30 .

[0065] Specifically, by setting the first sensor 12, the rotation parameters of the outer honeycomb body 30 can be detected. According to the rotation parameters, the power unit 40 can be controlled to stop rotating, the outer honeycomb body 30 can return to the starting position, and the circulation of the power unit 40 can be started or the filtration system can be stopped.

[0066] In a possible implementation, the first sensor 12 may include an angle sensor, a rotation speed sensor, etc.

[0067] According to one embodiment of the present invention, the filter further includes: a second sensor 14 , which is disposed on the open side of the accommodating cavity and is used to detect the airflow resistance passing through the filter element 20 .

[0068] Specifically, the second sensor 14 is provided to detect the air flow resistance passing through the filter element 20. If the resistance is greater than a certain threshold, the prompting unit 70 installed in the cab issues a prompt.

[0069] In a possible implementation, the second sensor 14 may be an air filter sensor.

[0070] According to an embodiment of the present invention, the valve 46 is further included. The valve 46 is disposed at one end of the pipeline 42 close to the gas storage tank 44 and is used to control the on / off state of the pipeline 42 .

[0071] Specifically, the gas is controlled by setting a valve body 46. When a shutdown command is received, the valve body 46 opens and the gas tank 44 sprays air. When the number of cycles reaches a preset value, the valve body 46 closes, the gas tank 44 is cut off, and the operation ends.

[0072] In a possible implementation, the valve body 46 may be a solenoid valve.

[0073] According to one embodiment of the present invention, it further includes: a support frame 50 and a bracket 52 ; the shell 10 is disposed on the support frame 50 ; the bracket 52 is disposed on the support frame 50 and connected to the gas tank 44 .

[0074] According to an embodiment of the present invention, the device further includes a working light 60 , which is disposed on the gas storage tank 44 and is used to indicate the working status of the gas storage tank 44 .

[0075] Specifically, by providing the working light 60 , the working status of the gas storage tank 44 can be easily observed.

[0076] According to the second aspect of the present invention, a control method for a filtration system is provided, comprising: obtaining the airflow resistance through the filter element 20; judging based on the airflow resistance, and determining that the airflow resistance reaches a preset threshold, then delivering a medium to the inner honeycomb body 32 in the filter element 20, and driving the outer honeycomb body 30 to rotate. During the interlaced rotation of the outer honeycomb body 30 and the inner honeycomb body 32, the medium passes through the inner honeycomb body 32 and the outer honeycomb body 30, and then impacts the surface of the filter element 20, thereby cleaning the filter element 20.

[0077] Specifically, after determining that the air resistance meets the preset threshold, the controller sends a signal to open the valve body 46, the work light 60 lights up, the gas tank 44 sprays air, and at the same time the power unit 40 drives the outer honeycomb body 30 to rotate, and the gas passes through the first through hole 34 and the second through hole 36 on the inner and outer honeycomb bodies 30 to clean the filter element 20.

[0079] Specifically, the time length characteristics of the outer honeycomb body 30 include the rotation time length of the outer honeycomb body 30 and the stop time length of the outer honeycomb body 30. After obtaining the time length characteristics of the outer honeycomb body 30, a judgment is made. When the rotation time length of the outer honeycomb body 30 meets a first preset time threshold, the motor stops rotating, and the outer honeycomb body 30 returns to the starting position, with the cells of the inner and outer honeycomb bodies 30 overlapping.

[0081] Specifically, under the premise of the above embodiment, after the outer honeycomb body 30 stops rotating, if the time for which the outer honeycomb body 30 stops rotating meets the second preset time threshold, the above motor rotation and stop process is cyclically started.

[0082] According to one embodiment of the present invention, after determining that the airflow resistance meets a preset threshold, the medium is transported to the inner honeycomb body 32 in the filter element 20, and the outer honeycomb body 30 is driven to rotate, which specifically includes: the outer honeycomb body 30 starts to rotate and stops rotating as a cleaning cycle; when it is determined that the number of cleaning cycles reaches a preset number, the rotation of the outer honeycomb body 30 is terminated.

[0083] Specifically, under the premise of the above embodiment, the outer honeycomb body 30 rotates until it stops rotating, which is a cleaning cycle, that is, a cycle. When the number of cleaning cycles is equal to the preset number, the outer honeycomb body 30 completely stops rotating, the working light 60 and the valve body 46 are closed, the gas tank 44 is cut off, and all work stops.

[0085] According to a fourth aspect of the present invention, a vehicle is provided, comprising the above-mentioned filtration system, or employing the above-mentioned control method of the filtration system during filtration, or comprising the above-mentioned powertrain.

[0086] According to an embodiment of the present invention, the present invention further includes: a cab and a prompting unit 70. The prompting unit 70 is provided in the cab and is used to prompt the working status of the filtering system.

[0087] Specifically, when it is determined that the air resistance is greater than the set value, the prompt unit 70 installed in the cab will issue a prompt, and the driver can use the operating hand to select to execute the next step. If the driver chooses to stop, the prompt unit 70 will stop prompting, the work light 60 will light up, the valve body 46 will open, and the air tank 44 will start to spray, and perform back-blowing resonance dust removal work.

[0088] In a possible implementation, the prompting portion 70 may be a buzzer.
