Detailed Description
For convenience of description, the present invention will be referred to in the context of the present invention by the terms "upper" and "lower", which are used in relative terms, with reference to the cyclonic separating apparatus when it is placed upright on a horizontal surface, i.e. in the manner shown in figure 2. It will be readily appreciated that these aspects will vary when the cyclonic separating apparatus is otherwise positioned.
As shown in fig. 1-7A, a first aspect of the present invention provides cyclonic separating apparatus comprising a primary cyclonic separating structure and a secondary cyclonic separating structure downstream of the primary cyclonic separating structure in the direction of airflow, wherein the primary cyclonic separating structure comprises a plurality of primary separation cones 301 (shown in fig. 2-3 and 5-6) and the secondary cyclonic separating structure comprises one or more secondary separation cones 302 (shown in fig. 7), and wherein the number of secondary separation cones 302 is less than the number of primary separation cones 301.
That is, the cyclone separation device of the invention comprises a two-stage multi-cone cyclone separation structure, during specific work, airflow firstly enters the first-stage cyclone separation structure to carry out gas-dust separation, dust with larger particles is separated out, the separated gas then enters the second-stage cyclone separation structure to carry out further gas-dust separation, fine dust is separated out, and therefore, the gas-dust separation rate can be improved through the separation of the two-stage multi-cone cyclone separation structure.
Preferably, the maximum inner diameter of the secondary separation cone 302 is larger than the maximum inner diameter of the primary separation cone 301, so that it is ensured that the air passage cross-sectional area of the secondary cyclonic separation structure is not reduced compared to the air passage cross-sectional area of the primary cyclonic separation structure, thereby not affecting the air velocity in the primary cyclonic separation structure and ensuring the separation efficiency of larger particles of dust in the primary cyclonic separation structure.
Preferably, the secondary separation cone 302 is arranged inside the primary separation cone 301 in the radial direction of the cyclonic separating apparatus. For example, a plurality of primary separation cones 301 are arranged near the periphery of the cyclonic separating apparatus, preferably circumferentially, as shown in figures 2-3 and 5, while one or more secondary separation cones 302 are arranged near the center of the cyclonic separating apparatus, preferably also circumferentially, whereby a difference in the number of secondary separation cones 302 near the center is conveniently achieved, i.e. the number of secondary separation cones 302 near the periphery is less than the number of primary separation cones 301 near the periphery. Meanwhile, the arrangement mode has the advantages of compact structure and capability of fully utilizing space, and each separation cone is conveniently and uniformly distributed.
Preferably, in the cyclonic separating apparatus of the present invention, the ratio of the number of primary separation cones 301 to the number of secondary separation cones 302 is 2:1, for example, in the preferred embodiment shown in the drawings, the number of primary separation cones 301 is 8 and the number of secondary separation cones 302 is 4. Preferably, more than two (two in the illustrated preferred embodiment) adjacent primary separation cones 301 and one secondary separation cone 302 form a two-stage cyclonic separation unit, and the overall cyclonic separation apparatus includes a plurality of two-stage cyclonic separation units, which facilitates uniform airflow between the separation cones.
Preferably, all primary separation cones 301 and secondary separation cones 302 are integrally formed, for example on the separator body 3 to be mentioned later.
Preferably, as shown in fig. 1, the cyclone separating apparatus comprises:
a separator body 3 on which said primary separation cone 301 and said secondary separation cone 302 are formed (preferably integrally formed), the preferred construction of the separator body 3 being as shown in figures 8-14;
the primary separation cover 5 is used for covering the upper port of the primary separation cone 301 to prevent the gas in the primary separation cone 301 from escaping through the upper port, and the primary separation cover 5 is provided with a primary gas outlet pipe 501 for being inserted into the primary separation cone 301, namely, being inserted through the upper port, so that the gas in the primary separation cone 301 can only be discharged through the primary gas outlet pipe 501; the preferred construction of the primary separating cap 5 is shown in FIGS. 15-19; and
the secondary separation cover 6 is used for covering the primary separation cover 5 and simultaneously covering the upper port of the secondary separation cone 302 to prevent gas in the secondary separation cone 302 from escaping through the upper port, and the secondary separation cover 6 is provided with a secondary gas outlet pipe 601 which is used for being inserted into the secondary separation cone 302, namely, is inserted through the upper port, so that the gas in the secondary separation cone 302 can only be discharged through the secondary gas outlet pipe 601; the preferred construction of the secondary separating cover 6 is shown in FIGS. 20-25.
Preferably, as shown in fig. 8-9, the upper port of the secondary separation cone 302 is higher than the upper port of the primary separation cone 301, and as shown in fig. 15 and 17, the primary separation cover 5 is provided with a first hole 502 matching with the shape of the upper end of the secondary separation cone 302 for the upper end of the secondary separation cone 302 to pass through. It can be seen that since the secondary separation cone 302 is provided with an air inlet 304 in the side wall near the upper port, the air inlet 304 protrudes outward in the tangential direction of the outer side wall of the secondary separation cone 304, and therefore the first bore section 502 has to be shaped such that said air inlet 304 can also pass through.
As shown in fig. 8, the gas inlet 303 of the primary separation cone 301 is disposed on the sidewall of the primary separation cone 301 and near the upper port of the primary separation cone 301, in a direction tangential to the sidewall of the primary separation cone 301, the gas inlet 303 preferably having a rectangular cross-section; similarly, gas inlet 304 of secondary separation cone 302 is disposed on a sidewall of secondary separation cone 302, and also proximate to an upper port of secondary separation cone 302, again oriented tangentially along the sidewall of secondary separation cone 302, gas inlet 304 preferably having a rectangular cross-section. In the case where the upper port of the secondary separation cone 302 is higher than the upper port of the primary separation cone 301, the lower edge of the air inlet 304 of the secondary separation cone 302 is preferably higher than the upper port of the primary separation cone 301, and therefore, when the primary separation cap 5 covers the upper port of the primary separation cone 301, both the upper port of the secondary separation cone 302 and the air inlet 304 may be located on the upper side of the primary separation cap 5, so that the primary separation cap 5 can isolate the air inlet of the primary separation cone 301 from the air inlet of the secondary separation cone 302, preventing the two-stage separation structure from becoming a single-stage separation structure.
Preferably, as shown in fig. 15-19, the primary separation cover 5 is provided with a partition 503 for separating the air inlets 304 of the secondary separation cones 302 from each other, so as to ensure that each secondary separation cone 302 corresponds to the air outlet of a different primary separation cone 301, for example, so that they form different cyclone separation units to ensure uniform air flow entering each secondary separation cone 302. The partition 503 is preferably a partition plate-like structure, and is preferably integrally formed on the upper surface of the primary separation cover 5.
Preferably, as shown in fig. 20-25, the secondary separation cover 6 is provided with a skirt 602 at its periphery for enclosing the space above the air outlet of the primary separation cone 301, so that the air exiting the air outlet of the primary separation cone 301 can only enter the corresponding secondary separation cone 302. In the assembled state, the skirt 602 and the partition 503 jointly divide the space between the primary and secondary separating caps 5, 6 into a plurality of cells, for example, each cell comprising the outlet openings of two primary separating cones 301 and the inlet opening of one secondary separating cone 302.
Preferably, the inner diameter of the secondary outlet pipe 601 is larger than the inner diameter of the primary outlet pipe 501, thereby ensuring that the total cross-sectional area of all secondary outlet pipes 601 is not reduced compared to the total cross-sectional area of all primary outlet pipes 501 in the case of a small number of secondary separation cones 302. The primary outlet pipe 501 and the secondary outlet pipe 502 are preferably both thin-walled pipes, and the wall thickness is less than 1mm, for example. In the assembled state, primary outlet pipe 501 is concentric with primary separation cone 301, and secondary outlet pipe 601 is concentric with secondary separation cone 302.
In the preferred embodiment shown in the figure, the maximum cross-sectional area of the secondary separation cone 302 is greater than or equal to 150% of the maximum cross-sectional area of the primary separation cone 301, and can be increased as much as possible when space permits, so as to prevent the air duct flow from being small because the total air duct cross-sectional area of the secondary separation cone 302 is too small, and if the total air duct cross-sectional area of the primary separation cone 301 is relatively large, the gas flow velocity in the primary separation cone 301 will be relatively reduced, which will result in insufficient rotation speed of the air flow in the primary separation cone 301, and the dust and dirt will not be rotationally separated but will be directly carried into the secondary separation cone 302, increasing the dust and dirt content of the secondary separation cone 302, increasing the separation pressure thereof, and also reducing the overall separation effect.
Preferably, as shown in fig. 6 and 6A, in the assembled state, the lower port of the primary outlet pipe 501 is lower than the lower edge of the inlet 303 of the primary separation cone 301 to prevent dust from being discharged directly through the primary outlet pipe 501 without separation. It is further preferred that the height of primary outlet pipe 501 is approximately 2 times the height of inlet 303 of primary separation cone 301 to prevent dust and dirt from escaping.
Similarly, as shown in fig. 7 and 7A, in the assembled state, the lower port of the secondary exit tube 601 is lower than the lower edge of the inlet 304 of the secondary separation cone 302 to prevent dust from being discharged directly through the secondary exit tube 601 without separation. It is further preferred that the height of secondary exit tube 601 be approximately 2 times the height of inlet 304 of secondary separation cone 302 to prevent dust and dirt from escaping.
Preferably, as shown in fig. 1 and 2, the cyclone separating device of the present invention further comprises a collector 1 disposed below the separator body 3 for collecting all the dirt separated by the entire cyclone separating device (i.e., each separation cone), and the lower ports of the primary separation cone 301 and the secondary separation cone 302 face the collector 1, preferably protruding into the collector 1.
Preferably, as shown in fig. 1, a collector gasket 2 is further disposed between the separator body 3 and the collector 1, and a lower port of the primary separation cone 301 and a lower port of the secondary separation cone 302 penetrate through the collector gasket 2. The function of the collector gasket 2 is to prevent dirt in the collector 1 from escaping. Correspondingly, the collector gasket 2 is provided with a plurality of bore sections for the gas-tight passage of the lower end opening of the first stage separation cone 301 and of the second stage separation cone 302, so that a seal is formed at the outer wall surface of the respective separation cone.
Preferably, as shown in fig. 8 and 10, the separator body 3 is provided with an air outlet channel, and an inlet end 305 of the air outlet channel is located radially inside the secondary separation cone 302, for example, at the center of the separator body 3. Preferably, the outlet end 306 of the outlet channel is located at the side of the separator body 3.
Preferably, as shown in fig. 15 and 17, the primary separating cover 5 is provided with a second hole portion 504 at a position corresponding to the inlet end 305 of the air outlet passage, and the secondary separating cover 6 is provided with a third hole portion 603 at a position corresponding to the second hole portion 504. In the assembled state, the inlet end 305 of the air outlet channel, the second hole portion 504 and the third hole portion 603 are aligned with each other such that the inlet end 305 of the air outlet channel communicates with the space above the secondary separation cover 6, so that the gas separated by the secondary cyclone separation structure can reach the inlet end 305 of the air outlet channel and can be discharged through the air outlet channel. Preferably, the inlet end 305, the second hole portion 504 and the third hole portion 603 of the air outlet channel have the same cross-sectional shape, so that the air flow can smoothly pass through and the air resistance can be reduced.
Preferably, as shown in fig. 1 and 2, the cyclone separating apparatus of the present invention further comprises a top cover 8 mounted on the secondary separating cover 6 to cover the air outlet of the secondary separating cone 302 in the same space as the third hole part 603, thereby allowing the air discharged through the air outlet of the secondary separating cone 302 to enter only the third hole part 603 and thus to be discharged only through the air discharge passage without gas by-pass. In addition, the top cover 8 also functions to prevent external air from directly entering the third orifice portion 603 without passing through the two-stage cyclone separation structure, thereby affecting the separation effect.
Preferably, as shown in fig. 1, a primary separation gasket 4 is disposed between the primary separation cover 5 and the separator body 3. The primary separation gasket 4 mainly functions to form a seal between the separator body 3 and the primary separation cover 5, prevent the gas which is not separated by the primary separation cone 301 in the separator body 3 from directly entering the secondary separation cone 302, and prevent the external air from entering the primary separation cone 301 through the upper port of the primary separation cone 301 to affect the separation effect.
Preferably, as shown in fig. 1, a secondary separation sealing gasket 7 is arranged between the secondary separation cover 6 and the top cover 8. The secondary separating gasket 7 mainly serves to form a seal between the top cover 8 and the secondary separating cover 6, to prevent dust from escaping, and to prevent outside air from entering and affecting the separating effect.
The air path of the entire cyclonic separating apparatus is shown in steps in figures 26 to 28 by means of dotted lines with arrows. As shown in fig. 26, the dirty gas enters the gas inlet 303 of the primary separation cone 301 from the gap of the primary separation cone 301 and enters the inside of the primary separation cone 301 along the tangential direction, the dirty gas performs a downward rotating motion in the cone, the dirt in the gas slowly stalls and falls down into the collector 1 under the influence of the self-gravity and the friction with the inner wall of the primary separation cone 301, so as to form a separation, and the cleaner gas after the separation is sucked from the middle primary gas outlet pipe 501 and enters the secondary separation cone 302. As shown in fig. 27, the gas after the primary separation enters the gas inlet 304 of the secondary separation cone 302 and enters the inside of the secondary separation cone 302 along the tangential direction, the gas is relatively clean at this time, but still has a small amount of dust, the part of the gas performs a downward rotating motion in the secondary separation cone 302, the small amount of dust in the gas slowly stalls and falls into the collector 1 under the influence of the self-gravity and the friction with the inner wall of the secondary separation cone 302, so that the secondary separation is formed, and the clean gas after the secondary separation is sucked away from the middle secondary gas outlet pipe 601. Then, as shown in fig. 28, the gas from the secondary outlet pipe 601 will be discharged along the outlet passage and leave the cyclone separation device, thereby completing the whole separation process.
The cyclone separation device of the invention forms a two-stage multi-cone separation structure by effectively arranging and separating a plurality of separation cones on the basis of the multi-cone separation structure in the prior art, thereby being capable of further separating in a two-stage multi-cone structure when the separation in the one-stage multi-cone structure is incomplete, and the separation effect is obviously higher than that of the existing single-stage multi-cone separation structure.
Particularly, the cyclone separation device of the invention enables the secondary separation cone to effectively separate fine dust which is not separated by the primary separation cone through skillful design of the relative position, the number relation, the size relation and the like of the secondary separation cone and the primary separation cone, thereby effectively ensuring the separation effect of the cyclone separation device.
In view of the above, a second aspect of the present invention also provides a vacuum cleaner comprising a cyclonic separating apparatus as hereinbefore described.
The dust collector of the invention can achieve the effects of high dust and dirt separation efficiency, low secondary pollution degree, long service life of the motor and the like without additionally arranging a separation device.
Those skilled in the art will readily appreciate that the above-described preferred embodiments may be freely combined, superimposed, without conflict.
It will be understood that the embodiments described above are illustrative only and not restrictive, and that various obvious and equivalent modifications and substitutions for details described herein may be made by those skilled in the art without departing from the basic principles of the invention.
