Description

Self-cleaning vacuum cleaner

technical field

The utility model relates to a self-cleaning vacuum cleaner in the field of air purifier equipment.

Background technique

A large amount of dust and debris will be generated in industrial processing and production. Vacuum cleaners are commonly used cleaning tools. The working principle of vacuum cleaners is to use a motor to drive the blades to rotate at a high speed, generate negative air pressure in a sealed shell, and absorb carpets with dust and debris. The surface of the floor, wall and other objects, and the dust is sucked into the dust-gas separation component together with the air, and the dust-gas separation component is equipped with a filter, the dust gas is filtered by the filter, and the dust is collected by the dust collector. , the filtered clean air is excluded from the vacuum cleaner body. During the decontamination process of the vacuum cleaner, whether it is a dust filter or a cyclone filter, there will be dust attached to the surface of the filter. The longer it is used, the more dust accumulated on the surface of the filter, which will gradually weaken the air permeability of the filter. The wind drops, thereby reducing the dust collection performance of the vacuum cleaner.

Utility model content

In view of the deficiencies in the prior art, the purpose of the present invention is to provide a vacuum cleaner with a self-cleaning function. By arranging a self-cleaning device in the filter cartridge, the vacuum cleaner can also clean the surface of the filter while vacuuming. The accumulated dust is blown off, which solves the problem that the filter is blocked by dust too quickly, so that the filter can maintain or restore a sufficient air permeability for a long time, thereby better ensuring that the vacuum cleaner can maintain a stronger force.

The utility model is achieved through the following technical solutions:

A self-cleaning vacuum cleaner, comprising a main engine, a filter cartridge and a fan, the main engine and the filter cartridge are mounted on a frame, and the fan is fixed in the main unit, and is characterized in that: a cylindrical filter is arranged in the filter cartridge, and a filter cartridge is arranged below the filter cartridge. There is a dust collecting bucket, an air outlet is arranged on the top cover of the filter cartridge, and the air outlet is connected to the exhaust cavity in the main unit through a pipeline. Between the filters, the self-cleaning device is a pulse cleaning component. The pulse cleaning component is driven by an external air source. The pulse cleaning component is controlled by the pulse cleaning controller. The dust air enters the filter cartridge through the suction port on the filter cartridge, and is filtered. After the filter in the cylinder is filtered, the air outlet on the top cover of the filter cylinder enters the exhaust cavity in the main engine, and is purified and discharged through the downstream filter on the exhaust cavity; the above technical scheme is further explained: the The pulse cleaning assembly includes a compressed air introduction pipe, a nozzle and a Venturi pipe. The compressed air introduction pipe is provided with a nozzle. The Venturi pipe is installed on the upper end of the cylindrical filter. Above the air inlet of the Venturi pipe is a nozzle. The air inlet pipe is communicated with the high-pressure steam drum through the isolation valve; the above technical scheme is further explained: the downstream filter is a high-efficiency activated carbon filter, which purifies the filtered air once, and improves the purification rate of the air; The above technical scheme is further explained: the dust collecting bucket is a mobile dust collecting bucket; the above technical scheme is further explained: a number of large-area cylindrical filters are arranged in the filter cylinder, and by increasing the filtering area To achieve the effect of improving the purification; the above technical scheme is further explained: the filter cartridge is provided with a negative pressure gauge for detecting the filter, and the condition of the filter is checked at any time.

Compared with the prior art, the utility model has the characteristics of improving the purification efficiency, enabling the filter to maintain or recover a sufficiently large air permeability for a long time, and better maintaining the strong suction of the vacuum cleaner.

Detailed ways

Below in conjunction with accompanying drawing, the content of the present utility model is further described:

As shown in the figure is the structure diagram of the self-cleaning vacuum cleaner, including the main engine 1, the filter cartridge 2, the downstream filter 3, the dust collecting bucket 4, the filter cartridge cover 5, the air outlet 6, the suction port 7, the pulse cleaning assembly 8, the fan 9 , High pressure steam drum 10 , Venturi tube 11 , isolation valve 12 , compressed air inlet pipe 13 and nozzle 14 . Self-cleaning vacuum cleaners are industrial vacuum cleaners that vacuum with a powerful airflow generated by a vacuum unit. After the product is sucked into the vacuum cleaner, the dust carried in the airflow is separated through the filter and discharged into the bottom mobile dust collection bucket. After vacuuming, you can take out the dust bin to clean up the garbage. A cylindrical filter is installed in the filter cartridge. Multiple filters can be set in the filter cartridge to increase the filtering area. A pulse cleaning component with self-cleaning function is arranged above the filter.
