Detailed Description
For the purpose of illustrating the technical content, the constructional features, the achieved objects and the effects of the invention in detail, reference will be made to the following detailed description of the embodiments in conjunction with the accompanying drawings.
As shown in fig. 1 to 3, a cyclone separator 100 according to an embodiment of the present invention includes: a dust cup 1, a top cover component 2 and a filter element component 3. The filter element assembly 3 includes an upper mounting body 31, a metal filter screen 32 with a plurality of filter holes 321, a lower mounting body 33 and a lower base 34. The dust cup 1 is of a structure with a closed bottom and an open upper part. The outside of the dust cup 1 is provided with a spiral air inlet duct 15 communicated with the inside of the dust cup 1, and the side wall of the dust cup 1 is provided with an air inlet 11 communicated with the spiral air duct 15. Due to the spiral air duct 15, the dusty air flow entering the dust cup 1 from the air inlet 11 is sent into the dust cup 1 in a spiral rotation mode, and the dusty air flow rotates in the dust cup 1 in a spiral mode, so that gas-solid separation is realized.
The internal structure of the cyclone separator 100 shown in fig. 4 is as follows:
the top cover assembly 2 is located at the upper portion of the dirt cup 1, and the top cover assembly 2 includes an upper end cover 21, a housing 22, a filter 23, and a cover plate 24. The housing 22 is fixed to the periphery of the upper end cap 21. The upper part of the dust cup 1 is connected to the housing 22 and the upper opening of the dust cup 1 is covered by the upper cover 21, the dust cup 1 is detachable from the housing 22, and the housing 22 is provided with an operation button 26 for unlocking the dust cup. The filter 23 is detachably mounted inside the upper cap 21 and is pressed against the inside of the upper cap 21 by a cover plate 24 located at the upper side. The filter 23 may be a HEPA type filter or a filter of a breathable cotton structure. The cover plate 24 is provided with an air outlet 25, and the air outlet 25 is located downstream of the filter 23.
As shown in fig. 3, the filter element assembly 3 includes an upper mounting body 31, a metal filter screen 32 with a plurality of filter holes 321, a lower mounting body 33, and a lower base 34. The upper end of the filter screen 32 is fixed to the upper mounting body 31, and the lower end thereof is fixed to the lower mounting body 33. As shown in fig. 4, the filter cartridge assembly 3 has a filter cartridge axial line X1, and the lower base 34 covers the lower side of the lower mounting body 33 and is fixed to the lower mounting body 33. It will be understood by those skilled in the art that the lower base 34 and the lower mounting body 33 are connected together by welding, bolting, clamping, etc. The inside of the upper mounting body 31 forms a cartridge outlet 35. The candle outlet 35 is located upstream of the filter 23, i.e. the air escaping from the candle outlet 35 will be filtered again after passing through the filter 23 and then discharged through the air outlet 25 to components located downstream of the cyclone separator 100.
As shown in fig. 4, the inner side of the dust cup 1 is provided with an upper retaining ring and a lower retaining ring at two different positions, namely an upper retaining ring 36 and a lower retaining ring 38; in addition to this, there is a dust skirt 37 and a central stub 39.
An upper retainer ring 36 is integrally formed on the upper end cap 21 and has a lower end portion projecting downward into the dust cup 1 from the inner surface of the upper end cap 21. The upper retainer 36 is located inside a part of the air inlet 11 and is shielded at the periphery of the upper portion of the filter mesh enclosure 32. The upper retainer 36 can space a portion of the air inlet 11 from the filter aperture 321 in the upper portion of the filter screen 32, thereby preventing some of the air entering the dirt cup 1 from the air inlet 11 from escaping directly through the filter aperture 321 in the upper portion of the filter screen 32 without cyclonic separation. An upper airflow passage 361 for guiding the dust-containing airflow to the filtering holes 321 on the upper part of the filter screen 32 from the bottom to the top is formed between the inner side wall surface of the upper retainer ring 36 and the upper part of the filter screen 32.
The lower retainer ring 38 and dust skirt 37 are integrally formed on the lower base 34. The dust retaining skirt 37 is located outside the lower base 34 and projects radially outward. The dust blocking skirt 37 and the inner wall surface of the dust cup 1 have a gap 12 therebetween, the dust blocking skirt 37 divides the space inside the dust cup 1 into a cyclone separation chamber 13 located at an upper portion and a dust collection chamber 14 located at a lower portion in the vertical direction, and the dust collection chamber 14 communicates with the cyclone separation chamber 13 through the gap 12. The lower retainer 38 is shielded at the periphery of the lower portion of the filter screen 32, and the dust-blocking skirt 37 can be separated from the filter holes 321 at the lower portion of the filter screen 32 by the lower retainer 38. A lower airflow passage 381 for guiding the dust-containing airflow to the filtering holes 321 at the lower part of the filter screen 32 from the top to the bottom is formed between the inner side wall surface of the lower retainer 38 and the lower part of the filter screen 32.
The bottom of the lower base 34 is also integrally formed with a central stub 39. A central stub tube 39 extends downwardly from the lower surface 382 of the dust skirt 37, the central stub tube 39 being located entirely in the central portion of the dirt collection chamber 14, the lower end of the central stub tube 39 being located above and remote from the inner bottom surface of the dirt cup 1. The central stub 39 has a center line X2 which is coincident with the filter element axis X1 at X2.
The upper retainer ring 36 can effectively prevent the dust-containing airflow flowing in from the air inlet 11 from being directly sucked to the upper part of the filter screen 32, after the airflow collides with the outer side wall surface of the upper retainer ring 36, large particle dust is thrown into the dust collection chamber 14 at the lower part along with the rotating airflow, and small particle dust enters the upper airflow channel 361 from the lower end part of the upper retainer ring 36 and then escapes from the filter holes 321 at the upper part of the filter screen 32.
In this embodiment, the lower retaining ring 38 is provided, so that at least a part of the dust-containing airflow colliding with the upper surface 371 of the dust-retaining skirt 37 directly impacts the outer wall surface of the lower retaining ring 38 to avoid directly entering the inside of the filter element 32 through the filter holes 321 at the lower part of the filter screen cover 32, thereby improving the gas-solid separation effect of the cyclone separator.
In this example, when the specific dimensions of the upper retainer ring 36, the lower retainer ring 38, the dust-blocking skirt 37 and the central tube 8 are set, the separation efficiency of the whole cyclone separator and the cleaning period of the filter core and the filter are fully considered, as shown in fig. 5 and 6, the specific dimensions are as follows: the height H3 of the upper retainer ring 36 is less than or equal to 1/3 of the height H0 of the filter screen cover. The distance H6 from the lower end edge of the upper retainer 36 to the upper edge of the air inlet 11 is 1/4-1/2 of the longitudinal height H7 of the air inlet 11. The height H4 of the lower retainer ring 38 is higher than the height H5 of the dust-blocking skirt 37 and is less than or equal to 1/3 of the height H0 of the filter screen cover. The inner diameter L2 of the upper air flow passage 361 is preferably 1/5-1/4 of the distance L1 between the inner wall surface of the dirt cup 1 and the outer wall surface of the filter screen 32, and the inner diameter L3 of the lower air flow passage 381 is preferably 1/5-1/4 of the distance L1 between the inner wall surface of the dirt cup 1 and the outer wall surface of the filter screen 32.
In this example, the outer diameter D2 of the widest part of the dust-retaining skirt 37 is 1/2-5/6 of the inner diameter D1 of the dust cup 1 at the corresponding position. The height H2 of the central stub 39 is less than or equal to 1/2 of the height H1 of the dust collection chamber 14. The outer diameter D4 of the central stub 39 is 1/2-2/3 of the inner diameter D3 of the dirt collection chamber 14.
Therefore, the dust and impurities can be conveniently thrown out of the dust collecting chamber 14, and the dust entering the dust collecting chamber 14 can be effectively prevented from rebounding to the upper cyclone separating chamber along with the rotating airflow. Therefore, on the premise of not influencing the spiral rising of the airflow, the dust-containing airflow is prevented from directly escaping to the filter hole to block the filter hole.
When the cyclone separator 100 is operated, when dust is present in the dust collecting chamber 14, the dust rotates in the dust collecting chamber 14 along with the rotation of the airflow, and when a certain amount of dust is accumulated, the dust is more likely to climb over the dust blocking skirt 37 as it approaches the dust blocking skirt 37. In this case, by providing a short central tube 39 in the dust collecting chamber 14 at the lower part of the dust skirt 37, so that the short central tube 39 is located at the "eye" of the cyclone, when the dust at the bottom of the dust collecting chamber rotates with the rotating airflow, the dust entering the dust collecting chamber will not move into the upper cyclone chamber 13 as the rotating airflow moves over the dust skirt 37 because there is no airflow inside the short central tube 39, and the dust will not move into the cyclone chamber 13. Thus, the provision of the central stub pipe 39 reduces the amount of dirt in the dirt-collecting chamber 14 which can pass over the dirt-retaining skirt 37 and enter the cyclonic separating chamber 13, thereby also reducing the risk of large particles of dirt blocking the filter openings after entering the cyclonic separating chamber.
As described above, the dust blocking skirt 37, the lower retaining ring 38 and the central short tube 39 are integrally formed with the lower base 34, which can simplify the internal structure of the cyclone separator and facilitate the production and assembly of the cyclone separator.
As shown in fig. 7, in the cyclone separator 100 of the present application, after the dust-containing airflow enters the dust cup 1 through the spiral air duct 15 and the air inlet 11, most of the airflow forms spiral airflow, a small portion of the airflow collides with the upper retainer 36 and rotates together with the spiral airflow, solid garbage such as dust and the like is thrown away from the filter element assembly 3 under the action of centrifugal force and falls into the dust collecting chamber 14 on the lower side from the cyclone separating chamber 13, and the primarily separated airflow passes through the filtering holes 321 in the middle of the filter screen 32, or passes through the upper airflow channel 361 and passes through the filtering holes 321 in the upper portion of the filter screen 32, or passes through the lower airflow channel 381 and passes through the filtering holes 321 in the lower portion of the filter screen 32 and enters the filter element assembly 3; while most of the dust falling into the dust collecting chamber 14 will be retained in the central short pipe 39 due to the action of the central short pipe 39, and a small part will pass over the dust blocking skirt 37 and collide with the upper surface 371 of the dust blocking skirt 37, and the collided dust will collide with the outer side wall of the lower baffle 38 again, and then fall into the dust collecting chamber 14 again, and cleaner airflow will rise along the filter core assembly 3 and pass through the filter holes 321 in the middle of the filter screen 32 or through the upper airflow channel and pass through the filter holes 321 in the upper part of the filter screen 32 and enter the interior of the filter core assembly 3; the air flow entering the interior of the filter element assembly 3 will exit through the filter element outlet 35 above the filter element assembly 3, and the exiting air flow will be further filtered again by the filter 23 and then escape through the air outlet 25.
The cyclone separator can reduce the blockage of the filter holes of the filter screen cover, thereby prolonging the single use time of the filter screen cover and reducing the cleaning frequency of the filter core.
The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is 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 protection scope of the present invention. All equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
