Detailed Description
The present invention will be described in further non-limiting detail with reference to the following preferred embodiments and accompanying drawings.
As shown in fig. 1 to 5, the present invention is a dust cup of a dust collector, which comprises a cup body 3, the cup body 3 is substantially cylindrical, a bottom cover 8 is connected to the bottom of the cup body 3, a dust cup cover 15 is connected to the top of the cup body 3, and a dust cup air outlet 16 is arranged on the dust cup cover 15. The dust cup air inlet 6 is arranged at the upper end of the cup body 3 and is tangent to the peripheral wall of the cup body 3.
The mesh filter 4 is arranged in the cup body 3 and has a cylindrical mesh part 41, a cone cover 42 connected with the mesh part 41 and a connecting part 43 formed at the upper end of the mesh part 41 and used for connecting with the dust cup body 3, and the dust collecting cylinder 7 is matched and connected at the lower end part of the cylindrical mesh part 41. Preferably, the dust collecting cylinder 7 is cylindrical, an opening is provided at the lower end, and the dust collecting cylinder 7 is integrally formed with the cylindrical mesh part 41.
As shown in fig. 2 to 4, the cyclone separator is arranged in the mesh filter 4, and comprises a body 1 and an air inlet 2 arranged above the body 1, wherein the air inlet 2 is tangential to the peripheral wall of the body 1.
The cyclone body 1 comprises a cylindrical part 10 and a truncated cone part 11, the bottom of the truncated cone part 11 is provided with a dust outlet 111, and the air inlet 2 is arranged at the upper end of the cylindrical part 10. Preferably, the air inlet 2 is formed integrally with the body 1, but may of course be provided as two detachable elements. It will be appreciated by those skilled in the art that the body 1 of the cyclonic separator may also be provided in the form of a truncated cone or a cylinder.
The air inlets 2 are arranged in two or more than two. The inlet 2 is formed by a plurality of vanes 21 arranged in a circular array to rotate, and the bottom 22 of each inlet 2 is arranged to rise spirally around the circumferential wall of the cyclone body 1. As shown in fig. 3, there is a height difference D between the lowest positioned intake vent 2 and the highest positioned intake vent 2.
Preferably, each of the blades 21 is shaped in an arc, and the cross-sectional shape of the blade 21 is trapezoidal. The upper ends of the blades 21 are located on the same plane, and the lower ends of the blades 21 are matched and connected with the air inlet bottom 22, so that a plurality of air inlet channels spirally rotating and rising around the peripheral wall of the cyclone separator body 1 are formed. In other words, the air inlet 2 is spirally and radially arranged around the peripheral wall of the cyclone separator, so that air carrying dust can spirally enter the interior of the cyclone separator in the longitudinal and radial directions of the cyclone separator, and a powerful cyclone mode is formed, thereby improving the dust separation efficiency.
The upper end of the cyclone is provided with an opening 23 in a spiral rotation, i.e. the peripheral wall of the opening 23 is in a spiral shape.
As shown in fig. 5, the duct 5 is detachably disposed at the upper end of the cyclone separator, and has a circular body 51, an air outlet 52 formed at the middle of the circular body 51, and a hollow cylinder 53 formed to extend along the air outlet, wherein the free end of the cylinder 53 is spiral and disposed corresponding to the spiral shape of the opening 23 of the cyclone separator.
Because each air inlet 2 of the cyclone separator is spirally and rotatably arranged, the height of each air inlet 2 has a drop, which can cause the air inlet of the cyclone separator to be inconsistent, and the free end of the cylinder 53 of the air guide pipe 5 is formed into a spiral shape and is arranged corresponding to the spiral shape of the opening 23 of the cyclone separator, so that the flow velocity of the air entering the cavity of the cyclone separator is guided and changed, and the flow velocity is uniform.
Of course, the spiral shape of the duct column 53 may or may not be identical to the spiral shape of the opening 23 of the cyclone, and the corresponding arrangement may be interpreted as long as the function of guiding and changing the flow velocity of the wind entering the cyclone chamber is achieved.
As shown in fig. 2, the dust cup of the dust collector further comprises a filter member 9 disposed between the air guide duct 5 and the dust cup cover 15.
As shown in fig. 1 to 5, during assembly, the mesh filter 4 is disposed in the cup body 3, the connection portion 43 of the mesh filter 4 is coupled to the upper end of the cup body 3, the cyclone separator is sleeved in the mesh filter 4, the air duct 5 is disposed at the upper end of the cyclone separator, and the bottom cover 8 is coupled to the bottom of the cup body 3 and the dust collecting tube 7.
When the dust collector works, air carrying dust enters the cup body 3 from the dust cup air inlet 6, and the dust cup air inlet 6 is tangent to the peripheral wall of the cup body 3, so that rotating airflow is generated, and the dust falls into the dust collection cavity 30 at the bottom of the cup body 3 under the action of centrifugal force and gravity. Due to the shielding effect of the shielding cage 42, the dust falling into the dust collecting chamber 30 is hardly caught up by the upper rotating airflow, thereby separating most of the dust. Air carrying a small amount of fine dust passes through the air inlet 2 of the cyclone separator, is guided by the spiral shape of the air guide pipe column 53, and spirally rotates around the longitudinal direction and the radial direction of the cyclone separator to enter the interior of the cyclone separator, so that powerful rotating airflow is formed. As the internal diameter of the frusto-conical portion 11 of the cyclonic separator is gradually reduced, the rotating airflow is further accelerated and centrifugal forces cause a small amount of fine dust entrained in the air to separate and fall through the dust outlet 111 into the dust collection canister 7. The air after the two times of separation passes through the air outlet 52 on the air guide pipe 5 and the filter piece 9 and is discharged from the air outlet 16 of the dust cup.
The air inlets 2 of the cyclone separator are formed by the blades 21 which are arranged in a rotating mode according to the annular array, and the bottom 22 of each air inlet 2 spirally rotates and rises around the cyclone separator body 1, so that air carrying dust can spirally rotate and enter the cyclone separator in the longitudinal direction and the radial direction of the cyclone separator, a powerful cyclone mode is formed, and the dust separation efficiency is improved.
It should be noted that the above-mentioned preferred embodiments are merely illustrative of the technical concepts and features of the present invention, and are intended to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
