The air inlet hole 3 of the pipe body 1 is connected to an air source 5 to blow air into the pipe body 1, and the air outlet holes 4 on the pipe body 1 blow air to the outer surface of the pre-filter 7, blowing away sundries such as dust and grass clippings on the outer surface of the pre-filter 7, achieving the purpose of cleaning the surface of the pre-filter 7 and preventing the pre-filter 7 from being blocked.

[0037] In this embodiment, the pipe body 1 forms a ring-shaped structure by bending, which is sleeved outside the pre-filter 7, and the pipe body 1 is fixed on the pre-filter 7 through the fixing bracket 2.

[0038] In this embodiment, a plurality of air outlet holes 4 are arranged on the pipe body 1, and the plurality of air outlet holes 4 are all arranged on the same side of the pipe body 1. After being installed on the pre-filter 7, it can blow air downward to achieve the purpose of cleaning the outer surface of the pre-filter 7.

[0039] In a preferred embodiment, the air outlet holes 4 are evenly arranged around the center of the ring-shaped pipe body 1.

[0040] In this embodiment, the air outlet holes 4 are evenly arranged around the center of the pipe body 1, which can better clean the outer surface of the pre-filter 7 and blow it cleaner.

[0041] In a preferred embodiment, the gas outlet directions of the plurality of gas outlet holes 4 are parallel, or are all inclined towards the annular center direction of the pipe body 1.

[0042] In this embodiment, the gas outlet directions of all the gas outlet holes 4 can be in the same direction, that is, blowing downward, or can be in different directions, such as all inclined towards the annular center of the pipe body 1, so that there is a certain included angle between the gas outlet holes 4 and the outer surface of the pre-filter 7, which can not only achieve the blowing of the surface of the pre-filter 7, but also improve the blowing efficiency.

[0043] In this embodiment, all the gas outlet holes 4 have the same inward inclination angle.

[0044] It can be understood that the inclination angle of the gas outlet holes 4 can be set according to the actual shape of the pre-filter 7, so as to better adapt to different types of pre-filters 7.

[0045] In a preferred embodiment, the number of the fixing frames 2 is multiple, and the multiple fixing frames 2 are uniformly arranged around the center of the annular pipe body 1.

[0046] In this embodiment, when the number of the fixing frames 2 is multiple, they are uniformly arranged in a circular array around the center of the annular pipe body 1.

[0047] Such a setting can ensure the balance of the fixing frame 2 when the fixing frame 2 supports the pipe body 1, thereby improving the cleaning effect of the sundries on the surface of the pre-filter 7.

[0048] In a preferred embodiment, the fixing frame 2 is fixedly connected or slidably connected to the pipe body 1.

[0049] Specifically, in this embodiment, the fixing frame 2 can be clamped on the pipe body 1 to achieve a fixed connection with the pipe body 1, or can be sleeved on the pipe body 1 through a ring sleeve structure to achieve a slidable connection between the fixing frame 2 and the pipe body 1.

[0050] The fixedly connected fixing frame 2 can better ensure the installation strength and installation stability of the pipe body 1 on the pre-filter 7.

[0051] The slidably connected fixing frame 2 can enable the pipe body 1 to better adapt to different pre-filters 7, thereby improving the applicability of the pipe body 1.

[0052] In this embodiment, the fixing frame 2 is fixedly connected, clamped or connected to the outer surface of the pre-filter 7, as long as it can achieve the installation of the pipe body 1 on the pre-filter 7 through the fixing frame 2.

[0053] In a preferred embodiment, the annular pipe body 1 has an adjustment gap.

[0054] In this embodiment, after an adjustment gap is provided on the annular tube body 1, the tube body 1 can be adapted to pre-filters 7 of different models, thereby improving the applicability of the tube body 1.

[0055] Specifically, when in use and the tube body 1 is used in matching with a pre-filter 7 having a larger diameter, after the adjustment gap on the tube body 1 is expanded, the tube body 1 can be sleeved on the pre-filter 7; when matching with a pre-filter 7 having a smaller diameter, by using the elasticity of the tube body 1 itself, the adjustment gap is reset to reach the minimum gap position.

[0056] In a preferred embodiment, the air inlet hole 3 is provided at the end of the tube body 1.

[0057] In this embodiment, the end where the air inlet hole 3 is located has a bend towards the outside. The air inlet hole 3 is provided at this end, which can facilitate the connection of the air inlet hole 3 with the pipeline on the air source 5.

[0058] It can be understood that in this embodiment, the air inlet hole 3 is provided at the end of the tube body 1, but it is not limited to this setting method at the end of the tube body 1. It can also be other setting methods, such as providing an air pipe communicating with the inside of the tube body 1 at any position on the side wall of the tube body 1, and the pipeline of the air pipe is the air inlet hole 3.

[0061] The pre-filter 7 is connected to the air filter 9, and air enters the engine through the pre-filter 7 and the air filter 9 to meet the air intake requirements of the engine.

[0062] In a preferred embodiment, a pressure sensor is provided at the inlet of the air filter 9.

[0063] When the controller 8 detects that the pressure value of the pressure sensor is greater than or equal to 5 Kpa, or when the time reaches the set time, the controller 8 issues an instruction to power on the fan to start working. The high-pressure air enters the pipe body 1 of the surface cleaning device 6 through the pipeline, and comes out through the air outlet holes 4 to blow off the accumulated grass on the surface of the air intake mesh holes or the outer surface of the pre-filter 7, avoiding the blockage of the air intake mesh holes and ensuring the air intake volume of the engine.

[0064] In a preferred embodiment, the air source 5 device is an electric fan, a mechanical fan or an engine fan.

[0065] It can be understood that the air source 5 device is a device that provides the air source 5, which is not limited to the above several devices, and it can also be other devices that can provide the air source 5.
