Abstract

The invention discloses a high efficiency air filter which is in a box-shaped structure and is characterized in that an air inlet is formed on a front wall plate, a rear cover grid is provided with an exhaust hole and is internally provided with a filtering material, a buffer cavity is formed in an externally convex manner on the grid corresponding to the air inlet, and two sides of the top of the grid are symmetrically provided with transverse guide slots; the filtering material is fixedly connected with a sheet which is fixedly connected with one end of a brake arm, a free end of the brake arm stretches to the outer side of the rear cover grid through the guide slots, and the brake arm can slide inside the guide slots. The grid is provided with the convex buffer cavity which can shunt the incoming flow, and simultaneously, a structure for manually shaking the filtering material is arranged, so the residual dust in sponge can be shaken off by manual compression and vibration, a matching structure for a guide plate and a positioning guide slot can connect a rear cover with a front cover so as to reduce the deformation of the front cover and the rear cover during engagement thereof, and with the help of the manual structure, a cover of the filter can be easily opened without dust falling; and the high efficiency air filter is simple in structure and convenient in operation, and enhances user satisfaction.

Description

technical field

[0001] The invention relates to a vacuum cleaner, in particular to a high-efficiency air filter. Background technique

[0002] Generally, a vacuum cleaner is a device that uses a vacuum to generate suction to inhale air, make the air flow through various filters, filter foreign objects in the air, and clean the room.

[0003] Generally speaking, a vacuum cleaner mainly includes a suction device and a suction pipeline. The suction device mainly formed by a motor and a fan is arranged in the body. The suction pipeline includes a suction head and a suction pipe. The suction head has a downward opening. The suction port communicates with the air inlet of the fan inside the body through the telescopic pipe and the flexible pipe of the suction pipe. When the vacuum cleaner is running, the motor drives the impeller of the fan to rotate at a high speed, exhausting the air in the vacuum cleaner, forming an instantaneous vacuum in the vacuum cleaner, and forming a rel...
