Problems solved by technology

This will lead to the decline of the dust removal effect of the dust box filtered by the HEPA filter, and shorten the replacement cycle of the HEPA filter; if the cyclone tube is used to filter dust or dirt, it is often necessary to install more layers of cyclone tubes to achieve better performance. Filtration effect, which invisibly increases the volume of the vacuum filter and the manufacturing cost

Embodiment Construction

[0017] refer to figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , a dust suction filter, including a dust box 1, a sealing cover 2, a filter core 3 is also vertically hoisted in the dust box 1, and an air inlet 11 arranged on the dust box 1 and an air inlet 11 arranged on the sealing cover 2 Outlet 21, the inner bottom of the dust box 1 is provided with a bone 12, the bone 12 is in the space between the filter core 3 and the side wall of the dust box 1, and the top of the bone 12 is not higher than the bottom of the filter core 3. Bone position 12 is the wheel rim shape that protrudes at dust box 1 bottom. When the vacuum cleaner works and sucks air, the air enters the dust box 1 through the air inlet 11 on the dust box 1, and forms a rotating vortex in the dust box 1. The rotating vortex formed in this way is actually a small tornado, but the tornado has the following Characteristics: The wind in a tornado is always cyclonic, the air rotates rapidly around the ax...

Abstract

The invention discloses a dust suction filter, comprising a dust box and a sealing cover, wherein, the inside of the dust box is also hung with a filter core, an air inlet and an air outlet uprightly, the air inlet is arranged on the dust box, the air outlet is arranged on the sealing cover, the bottom of the inside of the dust box is provided with a skeleton position, and the skeleton position is positioned in a space between the filter core and the side wall of the dust box and is not higher than the bottom of the filter core. The device has very simple structure, greatly enhances the dust removal efficiency and also realizes the functions of smaller volume and bigger dirt storage capacity.

Description

technical field [0001] The invention relates to a dust removal device, in particular to a dust suction filter. Background technique [0002] The first generation of vacuum cleaners generally have a cloth bag or paper tape for absorbing dust inside, which cannot be cleaned automatically, and will block the dust collection channel due to too much absorbed dust, which will greatly reduce the suction of the vacuum cleaner and greatly affect the quality of the vacuum cleaner. dust collection effect. In order to achieve the same dust collection effect, it is often necessary to increase the operating power to achieve the same dust collection capacity, which greatly increases energy consumption. [0003] In the second generation, HEPA filters are used to replace traditional cloth bags or paper bags. HEPA is the abbreviation of High Efficiency Particulate Air FILTER (High Efficiency Particulate Air Filter), which is an internationally recognized best high-efficiency filter material....
