Description

TECHNICAL FIELD

[0001] The present application relates to the dust collector related technical field, especially to a dust cup new cyclone assembly. BACKGROUND

[0002] The dust collector is mainly composed of dusting, dust suction and dust filtering three parts, generally including a series of commutator motor, centrifugal fan, dust filter (bag) and dust suction accessories. The power of the general dust collector is 400-1000W or higher, and the power of the portable dust collector is generally 250W or less. The dust collector can remove dust, mainly because its "head" is equipped with an electric blower. The blower has a fan wheel on the rotating shaft. After being powered on, the blower will generate a high suction force and pressure at a speed of 500 revolutions per second. Under the action of suction force and pressure, air is discharged at high speed, and the air in the front end of the blower is constantly supplemented, resulting in a transient vacuum inside the dust collector, and a negative pressure difference is formed with the atmospheric pressure outside. Under the action of this pressure difference, dust-containing air is sucked in. Dust and other impurities pass through the carpet or floor brush, long connecting pipe, elbow, hose and hose joint into the dust filter bag, and dust and other impurities are retained in the dust filter bag. After the air is purified by the filter, it is discharged from the tail of the machine body.

[0003] Dust cup filtering is to separate garbage and gas through high-speed rotation of the motor vacuum air flow, and then purify the air through HEPA and other filter materials to avoid secondary pollution. The advantage is that the dust bag does not need to be replaced frequently; the disadvantage is that it needs to be cleaned after dusting. Dust cup filtering is the main filtering way of the dust collector, and most dust collectors are dust cup filtering. It is also an upgrade of dust bag filtering. It also has the advantage of no consumables, avoiding secondary investment of funds. The existing dust cup has the problem of easy clogging of the filter screen during use. SUMMARY

[0004] The present application is to overcome the above-mentioned shortcomings in the prior art, and provides a dust cup new cyclone assembly which is not easy to block the filter screen.

[0005] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme:

[0006] A dust cup new cyclone assembly, comprising a dust cup body, a dust cup dust baffle, a cyclone cone, a cone cover plate and an air inlet net rack, the dust cup dust baffle, the cyclone cone, the cone cover plate and the air inlet net rack are all arranged in the interior of the dust cup body, the lower end of the dust cup body is internally provided with an air inlet round pipe, the dust cup dust baffle is installed on the air inlet round pipe, the cyclone cone is provided with an air inlet pipe, a separation core and an air outlet, the cyclone cone is connected with the dust cup dust baffle through the air inlet pipe, the air inlet pipe of the cyclone cone is communicated with the air outlet through the separation core, the cone cover plate is installed on the side of the cyclone cone, the air inlet net rack is installed on the air outlet of the cyclone cone, the side of the separation core is provided with a plurality of uniformly distributed guide fins, and the guide fins are uniformly distributed in the counterclockwise direction with the separation core as the center.

[0008] As a preferred, the left side of the cyclone cone is a separation cavity, the right side of the cyclone cone is an air outlet cavity, the air inlet pipe is communicated with the separation cavity of the cyclone cone, the separation core is installed in the separation cavity of the cyclone cone, the separation cavity of the cyclone cone is communicated with the air outlet cavity of the cyclone cone through the separation core, the cone cover plate is installed on the air outlet cavity of the cyclone cone, the separation cavity is provided with a dust removal port at the position where the air inlet pipe is located on the outside, and the depth of the separation cavity on the outside of the separation core gradually decreases from the air inlet pipe to the dust removal port in the counterclockwise direction of the separation core. Through the above structural design, the dust entering the air inlet pipe is centrifugally rotated counterclockwise, so that the dust can be thrown onto the inner wall of the separation cavity, and the dust is discharged from the dust removal port under the action of its own gravity, thereby greatly improving the filtering effect.

[0009] As preferred, the shape of the separation core is cylindrical, the upper end surface of the separation core is provided with air outlet meshes, the guide vanes are arranged on the outer surface of the separation core and are uniformly distributed on the outer surface of the separation core, a through hole is arranged between two adjacent guide vanes, the lower end surface of the separation core is communicated with the air outlet cavity, the cross section of the guide vanes is in the shape of an arc, one end of the guide vanes is mounted on the side surface of the separation core and is integrally formed with the separation core, the other end of the guide vanes is provided with an arc-shaped cutting surface on the outer surface, the arc-shaped cutting surfaces on all the guide vanes are on a circle with the same diameter, and the length of the guide vanes is greater than the distance between two adjacent guide vanes on the side surface of the separation core.
