In other words, the airflow entering the cyclone 11 from the vent 103 is blocked by the windshield 16 and the connecting plate 154, so as to avoid the direct rise of the dusty air, so that the dusty airflow can spiral along the extension direction of the deflector 15 in a container. Rising, so as to form a spiral airflow, so that the dust can be thrown out by centrifugal force. Thus, the dust-laden airflow can be easily spiraled up, avoiding the direct rise of the surface airflow to cause poor filtering effect and clogging of the filter, and improving the separation efficiency and separation effect of the cyclone separator 1 on the dust-laden airflow. Also, throwing out dust and the like can reduce the amount of dust and the like passing through the filter.

Advantageously, the wind deflector 15 is the bottom wall of the cyclone 11, and the cyclone separator inlet 101 is formed on the wind deflector 15, in other words, the cyclone 11 includes a cylindrical side plate 111 and the wind deflector 15, and the wind deflector 15 is set Inside the cylindrical side plate 111 , and the wind deflector 15 is ring-shaped, and the middle part of the ring-shaped wind deflector 15 forms the cyclone separator inlet 101 . Therefore, the wind deflector 15 is directly used as the bottom wall of the cyclone 11, so that the structure of the cyclone 11 is simple, the forming of the cyclone 11 is facilitated, and the forming efficiency of the cyclone 11 is improved.

Those skilled in the art can understand that the wind deflector 15 of the present invention may not be the bottom wall of the cyclone 11 , for example, the cyclone 11 is cylindrical with a closed bottom and the wind deflector is arranged in the cyclone 11 .

In addition, it is also possible to use a helically extended plate body and a connecting plate connecting the first and last ends of the helical plate body to cooperate to form the air guiding structure.

Thus, the air guide tube 14 is sleeved on the inner wall of the air inlet pipe 17, which can improve the sealing performance of the joint between the air guide tube 14 and the air inlet tube 17, so that the air guide tube 14 can close the air inlet tube 17. Moreover, the cooperation between the protrusion 171 and the slot 141 is used to connect the air guiding cylinder 14 with the air inlet pipe 17, which facilitates the installation of the air guiding cylinder 14 and improves the installation efficiency of the cyclone separator.

In addition, those skilled in the art can understand that the air guiding cylinder 14 can also be integrally formed with the air inlet pipe 17 , or the air guiding cylinder 14 and the air inlet pipe 17 can be connected together by welding, bolting, clamping and the like.

In other words, 0.5H2≤H1≤H2. Thus, the wind guiding effect of the cyclone 11 is improved, and the airflow is facilitated to spiral upward.

Further, the distance H3 between the end cover 12 of the cyclone separator and the upper edge of the cyclone tube 11 is not greater than the height H1 of the wind guide plate 15 . Thus, impurities such as dust are easily thrown out, thereby not only avoiding the accumulation of dust in the cyclone tube 11, but also facilitating the accumulation of impurities such as dust in the dust cup.

Advantageously, the radius R1 of the filter 13 is not greater than half of the radius R2 of the cyclone 11, in other words, the distance R3 between the cyclone 11 and the filter 13 in the radial direction is not less than half the radius R2 of the cyclone 11, and the cyclone 11 and the filter 13 are not less than half of the radius R2 of the cyclone 11. The distance R3 between the filters 13 in the radial direction is not greater than the radius R2 of the cyclone 11 . In other words, the difference R3 between the radius of the cyclone 11 and the radius of the filter 13 is not less than half of the radius R2 of the cyclone 11, and the difference R3 between the radius of the cyclone 11 and the radius of the filter 13 is not greater than The radius R2 of the cyclone 11 . That is, 0.5R2≤R1≤R2. Thereby, it is convenient for dust and impurities to be thrown out, avoiding the clogging of the filter 13 caused by impurities such as dust being adsorbed on the filter 13, and avoiding the high dust removal frequency of the filter cotton after the dust passes through the filter 13.

Therefore, the cyclone separator of the present invention can improve the separation efficiency of dusty airflow.

As shown in Figures 1 to 7, in a specific embodiment of the present invention.

The utility model provides a new cyclone separator 1, which realizes the high airtightness and high suction of the cyclone separator 1 while ensuring low cost.

Specifically, the cyclone separator 1 comprises: a cyclone tube 11, a filter 13 placed at the center of the cyclone tube 11, a cyclone separator end cover 12 positioned above the filter 13, the cyclone separator end cover 12 and the cyclone tube 11 There is a gap between the upper edges, and an air inlet pipe 17 is connected to the center of the bottom of the cyclone 11. The dust-laden gas enters the cyclone 11 through the air inlet pipe 17 and then accelerates the rotation through the wind deflector 15 inside it to guide the wind. The plate 15 is located between the air inlet pipe 17 and the filter 13 .

The air intake structure under the center of the cyclone separator 1 reduces power loss, and at the same time the ash throwing position is moved up to the maximum. Using the high-efficiency cyclone separator, the dust-laden airflow accelerates on the spiral runway, and the 360-degree free throwing It is no longer limited by the location of the ash throwing, so that the separation is more thorough. At the same time, hair and other strips can be easily thrown out. The suction of the whole machine will no longer drop quickly due to the clogging of the filter cotton, which will greatly improve the separation efficiency and prolong the life of the machine. The number of cleanings of the filter cotton.

Those of ordinary skill in the art can understand that the end cover 12 of the cyclone separator and the filter 13 can be formed as one body or assembled after forming multiple parts; the air inlet pipe 17, the wind deflector 15 and the cyclone tube 11 can be integrated After forming or forming a plurality of parts, assemble; filter 13, cyclone separator end cover 12 and air inlet pipe 17 can be formed in one body or assembled after forming a plurality of parts; wind deflector 15 and cyclone tube 11 can be formed in one body Or assemble after forming multiple parts.

The air intake structure under the center of the dust collection device 100 greatly shortens the length of the air intake pipe 17, reduces power loss, and throws dust freely in all directions in 360 degrees, no longer limited by the dust throwing position, so that the separation is more thorough, and at the same time Strips such as hair can also be easily thrown out, and the suction of the whole machine will no longer drop quickly due to the clogging of the filter cotton, which will greatly improve the separation efficiency and prolong the cleaning times of the filter cotton.

The vacuum cleaner according to the embodiment of the utility model has a brand-new air duct structure to achieve high suction force, low noise, small size, light weight, and simple assembly. That is, the air duct of the dust collection and separation system is short and efficient, and the silent air duct is long and unobstructed.

The structure adopts the cyclone separation structure with central air intake. After a short period of guidance, the dusty air directly enters the high-efficiency separation chamber of the dust cup, and the dust and gas are separated quickly. The wall enters the silent air duct system, that is, the steady flow chamber, flows into the motor, from the motor air outlet to the motor inner cover, and then passes through the small hole of the motor inner cover to silence the motor outer cover, and enters through the passage between the motor inner cover and the outer cover. The passage formed by the motor cover and the casing returns to the outside air after being silenced by the wind-out sponge.

In terms of cost, this solution removes the traditional side air intake duct in the dust collection air duct, which reduces material costs and labor costs; in terms of performance, because the air duct is short and smooth, the power loss is small, and the The diversion air duct of the high-efficiency separation chamber allows the dust and gas to be separated more thoroughly.
