[0005] In order to achieve the above object, the solution of the utility model is:
[0006] An air return port cleaning device includes a housing, a grille, a blow pipe and a roller brush; a clean air chamber and a cleaning chamber are separated in the housing by a partition, and an opening for communicating the clean air chamber with the cleaning chamber is reserved at the bottom of the partition; an air inlet and an air outlet are arranged in the clean air chamber; a collection bin is arranged below the cleaning chamber; the grille is arranged in the housing in a circular motion or a reciprocating motion manner, so that a part of the grille is movably matched in the clean air chamber or the cleaning chamber through the opening; the blow pipe and the roller brush are both arranged in the cleaning chamber, the blow pipe performs pulse blowing on the grille, and the roller brush is used for brushing the debris on the grille.
[0007] Two power rollers of the same height are arranged in the housing. The two power rollers are respectively located in the clean air chamber and the cleaning chamber and are close to the inner wall of the housing. The grille is wound around the two power rollers and is driven by the two power rollers to perform circular motion.
[0008] Preferably, the blow pipe is arranged at the same height as the power rollers and is located between the two power rollers.
[0009] The air return port cleaning device further includes an air bag arranged on the surface of the housing; a pulse valve is arranged between the air bag and the blow pipe.
[0010] Preferably, the air return opening cleaning device further includes an air pump assembly communicated with the air bag, and a pulse controller electrically connected to the pulse valve.
[0011] After adopting the above technical solution, the utility model has the following technical effects:
[0012] In the utility model, the grille is arranged between the clean air chamber and the cleaning chamber to perform circular movement or reciprocating movement. The part of the grille contaminated with sundries can move to the cleaning chamber, and automatic cleaning is realized through the blowing pipe and the roller brush. The relatively clean part after cleaning then moves to the clean air chamber to continue blocking sundries, which can ensure that some grilles in the clean air chamber are in a relatively clean state, ensure that the flow capacity of the equipment is in a stable and efficient state, and the equipment does not need to stop during the automatic cleaning process.
