With the development of science and technology, dust collectors gradually enter people's lives and become important cleaning tools. However, when the dust collector works, environmental garbage such as hair, dust, floccules and the like is easy to wind or attach to the outer wall surface of the filter cylinder, if the filter holes are easily blocked due to untimely cleaning, the normal work of the dust collector is affected, and when a user cleans the filter cylinder, the dust collector needs to be detached, so that time and labor are wasted, the dust collector is easily damaged, and the use experience is poor.

Therefore, the utility model provides a to above-mentioned problem, provide a whirlwind awl subassembly and dust catcher, can solve or partly solve environmental waste such as hair, dust, flocculus twine easily or depend on straining a section of thick bamboo outer wall, cause to strain a section of thick bamboo and block up the defect.

The cyclone cone assembly and the vacuum cleaner provided by the present invention for enhancing dust agglomeration will be described with reference to fig. 1 to 4.

In the related art, a dust collector comprises a shell, a fan and a cyclone cone assembly, wherein the shell is provided with an air outlet and an air inlet, and a cover body is arranged at the air outlet of the shell. The air inlet and the air outlet form an air passage in the shell, and the fan and the cyclone cone assembly are arranged in the air passage.

The working principle of the dust collector is as follows: the air inlet of casing sets up along dust collection chamber tangential, opens the fan after, dirty air gets into the dust collection chamber after, can rotate around the barrel, dirty air receives the centrifugal force effect, and dust quality wherein is big, and the dust hits the internal face to the casing under the centrifugal force effect, and the dust slides down and deposit in lid department to the one end of lid along the inner wall of casing under the effect of gravity. The gas with smaller mass enters the interior of the cyclone cone through the filtering hole on the cyclone cone, the gas outlet of the cyclone cone is communicated with the gas outlet of the shell, and thus the gas after dust-gas separation can be discharged into the air again through the gas outlet.

However, because the air pressure at the center of the cyclone is low, under the action of negative pressure, environmental garbage such as hair, dust, floccules and the like deposited on the cover body can rise along with the airflow and re-enter the space where the cyclone cone is located, and the environmental garbage is attached to or wound on the cyclone cone, so that the filter hole is easily blocked.

As shown in fig. 1, the present invention provides a cyclone cone assembly for strengthening dust agglomeration, which is suitable for being disposed in a vacuum cleaner, comprising: a cylinder body 1 and a dust baffle 2; the cylinder body 1 comprises a filter cartridge 11 and a cyclone center cylinder 12; the first end of the filter cartridge 11 is communicated with the first end of the cyclone center cylinder 12; the dust baffle 2 extends in a ring shape along the circumferential direction relative to the central axis of the cylinder 1, and at least one of the first end of the filter cylinder 11 and the first end of the cyclone central cylinder 12 is connected with the inner side edge of the dust baffle 2.

In the embodiment, by arranging the filter cartridge 11, after the fan 5 is started, impurities in the dirty air rotating around the filter cartridge 11 can be filtered, so that the impurities larger than the filter holes of the filter cartridge 11 are left outside the filter cartridge 11, clean air enters the filter cartridge 11, and the dirty air is separated from dust; due to the negative pressure action of the center of the cyclone and the negative pressure action of the fan 5, the environmental garbage can be lifted in the dust collection cavity 43, and the dust baffle plate 2 is arranged on the barrel body 1, so that the raised environmental garbage can be blocked to a certain extent by the dust baffle plate 2 relative to the raised structure of the barrel body 1, and partial environmental garbage can be prevented from entering the cavity where the filter cartridge 11 is located; through setting up whirlwind center tube 12 in the whirlwind center, make environmental waste raise and revolve round whirlwind center tube 12, because the negative pressure effect, environmental waste twines gradually on the lateral wall of whirlwind center tube 12 at rotatory in-process, strengthens environmental waste's reunion power, effectively reduces raising of environmental waste to reduce and strain the filtration pore blocking phenomenon of a section of thick bamboo 11.

The filter cartridge 11 is a cylinder 1 with a plurality of filter holes on the side wall, the interior of the filter cartridge 11 is communicated with the dust collecting cavity 43 outside the filter cartridge 11 through the filter holes on the side wall of the filter cartridge 11, and the filter holes can be used for filtering environmental garbage in dirty air so as to separate the environmental garbage larger than the filter holes from the air.

In some embodiments, the filter cartridge 11 may be a cylindrical structure with a sidewall provided with a through hole array, or may be a filter screen extending in a circumferential direction relative to a central axis of the cylinder 1, which is not limited in this embodiment.

In some embodiments, the material of the filter cartridge 11 may be a metal material or a rigid plastic material, such as fine steel or PVC, as long as the filtering requirement can be met, which is not limited in this embodiment.

In some embodiments, the port diameter of the first end of the filter cartridge 11 is smaller than the port diameter of the second end of the filter cartridge 11, which second end of the filter cartridge 11 faces away from the first end of the filter cartridge 11.

Specifically, the filter cartridge 11 may be a tapered cartridge, with a first end of the filter cartridge 11 having a smaller port diameter than a second end of the filter cartridge 11, the second end of the filter cartridge 11 facing away from the first end of the filter cartridge 11. The conical configuration of the filter cartridge 11 allows the dirty air to spiral and sink at an increased rate within the filter cartridge 11, increasing the efficiency of the dust and air separation.

The central axis of the cyclone central cylinder 12 coincides with the central axis of the filter cylinder 11, after dirty air enters the dust collection cavity 43 through the air inlet 41, the dirty air rotates around the cylinder 1 to form cyclone, the filter cylinder 11 and the cyclone central cylinder 12 are located at the center of the cyclone, and the cyclone central cylinder 12 is located at a lower position.

It should be noted that, the internal airflow at the center of the cyclone rotates at a high speed, the flow rate of the internal air is high, the pressure is low, and the flow rate of the external airflow at the center of the cyclone is low, and the pressure is high, so that the environmental garbage such as hair, dust, floccule and the like deposited at the cover 45 at the center of the cyclone rises along with the rotation of the airflow.

Because the cyclone center tube 12 is located at the center and lower position of the cyclone, the rotation center of the environmental garbage when the environmental garbage rotates and rises along with the airflow is the cyclone center tube 12, and due to the action of negative pressure, the environmental garbage can gradually attach to and wind the outer side wall of the cyclone center tube 12 in the rotation process and gradually move upwards along the outer side wall of the cyclone center tube 12. The connection part of the cyclone central cylinder 12 and the filter cylinder 11 is provided with a dust baffle plate 2 with an annular structure, the dust baffle plate 2 protrudes relative to the cyclone central cylinder 12, the upward moving path of the environmental garbage can be cut off, and the environmental garbage can gradually gather at the included angle position where the dust baffle plate 2 is connected with the cyclone central cylinder 12. The cyclone central cylinder 12 and the dust baffle 2 have an agglomeration effect on the environmental garbage, the environmental garbage is reduced to a certain extent, and the blockage of the filter holes of the filter cylinder 11 is effectively reduced. Meanwhile, as the environmental garbage is attached to and wound on the outer side wall of the cyclone central cylinder 12, a user only needs to take down the environmental garbage on the outer side wall of the cyclone central cylinder 12 when cleaning the dust collector, thereby facilitating the cleaning of the dust collector by the user.

In this embodiment, the filter cartridge 11 is connected to the cyclone center cylinder 12 in a detachable manner, such as a plug-in connection or a screw connection, which is not limited in this embodiment. The detachable connection mode of the filter cartridge 11 and the cyclone center cylinder 12 is convenient for a user to replace the old blocked filter cartridge 11, and the use is more convenient.

Wherein, dust board 2 is connected with barrel 1, and specifically, dust board 2 can with barrel 1 fixed connection, for example welding or gluing, and dust board 2 also can be dismantled with barrel 1 and be connected, for example threaded connection or buckle connection, and this embodiment does not limit this.

Specifically, there are various connection positions of the dust baffle 2 on the cylinder 1, for example, the inner side edge of the dust baffle 2 is connected to the first end of the filter cylinder 11, or the inner side edge of the dust baffle 2 is connected to the first end of the cyclone center cylinder 12, or the inner side edge of the dust baffle 2 is connected to both the first end of the filter cylinder 11 and the first end of the cyclone center cylinder 12, which is not limited in this embodiment.

It should be noted that the dust guard 2 extends in a ring shape along the circumferential direction relative to the central axis of the cylinder 1, and the dust guard 2 protrudes relative to the cylinder 1, so as to block the raised environmental garbage to a certain extent.

Wherein, the dust collecting chamber 43 is divided into a first chamber and a second chamber by the dust baffle 2, the filter cartridge 11 is arranged in the first chamber, and the cyclone center cylinder 12 is arranged in the second chamber.

Further, as shown in fig. 2 and 3, the dust guard 2 is provided with a through hole 21. The air inlet side of a fan 5 in the dust collector faces towards the filter cylinder 11, in the working process, the suction force of the fan 5 forms negative pressure, and due to the existence of the dust baffle plate 2, the negative pressure effect of the fan 5 enables air flow to bypass the dust baffle plate 2 and enter the first cavity from the second cavity, so that the environmental garbage attached to or wound on the outer side wall of the cyclone central cylinder 12 bypasses the dust baffle plate 2 and enters the first cavity, and the agglomeration force of the environmental garbage is reduced.

It should be noted that, after the through hole 21 is formed in the dust baffle 2, the negative pressure of the fan 5 causes the gas in the second cavity to flow to the first cavity through the through hole 21, and since the opening area of the through hole 21 is smaller than the area of the dust baffle 2, the negative pressure is dispersed by the through hole 21, and since the radial distance between the through hole 21 and the cyclone central cylinder 12 is smaller than the radial distance between the outer side of the dust baffle 2 and the cyclone central cylinder 12, the effect that the environmental garbage is adsorbed outwards due to the negative pressure along the diameter direction of the cyclone central cylinder 12 can be reduced.

Further, as shown in fig. 3, a plurality of through holes 21 may be formed in the dust guard 2, and the plurality of through holes 21 are circumferentially distributed with respect to the central axis of the cylinder 1.

In this embodiment, the plurality of through holes 21 are arranged to disperse the negative pressure of the fan 5, further enhance the agglomeration of the environmental garbage, and enhance the agglomeration force of the environmental garbage attached or wound on the outer sidewall of the cyclone central cylinder 12.

Further, the number of the through holes 21 may be set to 8 to 16, and the diameter of the through holes 21 may be set to 3 to 9mm. A large number of experiments carried out by the inventor prove that when the diameter of the through hole 21 is set to be 3-9 mm, the blocking of the through hole 21 caused by the upward rise of environmental garbage due to the negative pressure effect can be avoided while the agglomeration force of the environmental garbage is increased.

Further, as shown in fig. 4, the cyclone center cylinder 12 includes a first cylinder section 121 and a second cylinder section 122; the first end of the first cylinder section 121 is communicated with the first end of the filter cartridge 11, and the second end of the first cylinder section 121 is communicated with one end of the second cylinder section 122; the port diameter of the first end of the first barrel section 121 is greater than the port diameter of the second end of the first barrel section 121.

In this embodiment, one end of the second cylinder section 122 is close to or the same as the port diameter of the second end of the first cylinder section 121, so that the environmental garbage attached or wound on the second cylinder section 122 can smoothly move to the first cylinder section 121 under the action of the negative pressure.

The first cylinder section 121 is of a conical structure, the diameter of a port at the first end of the first cylinder section 121 is larger than the diameter of a port at the second end of the first cylinder section 121, the rotating radius of the environmental garbage in the rotating and rising process around the first cylinder section 121 is gradually increased, and the rotating speed is gradually reduced until the environmental garbage is gathered at the connecting position of the dust baffle 2 and the second end of the first cylinder section 121. The conical structure design of the first barrel section 121 can reduce the rotation speed of the environmental garbage, and prevents the environmental garbage from colliding with the dust baffle 2 due to the fact that the rotation speed is too fast, so that the environmental garbage is dispersed, and the agglomeration force of the environmental garbage is effectively enhanced.

It should be noted that although the dirty air is filtered by the filter cartridge 11 to filter out the large-sized environmental garbage in the dirty air, the small-sized environmental garbage still cannot be filtered out, and continues to rotate in the filter cartridge 11 with the air, when the mixture of the air and the environmental garbage touches the inner side wall of the cyclone central cylinder 12, the small-sized environmental garbage will rotate clockwise along the side wall and deposit downwards at the other end of the second cylinder section 122, so as to separate the small-sized environmental garbage, and further play a role in cleaning the air.

In some embodiments, the upper end of the cylinder 1 is provided with the filter layer 8, so that the gas can spirally rise along the rotation center line and is discharged from the exhaust port through the filter layer 8, the gas is further filtered by the filter layer 8, environmental garbage in the gas is effectively filtered, and the air cleaning effect is further achieved.

Wherein, the filter layer 8 comprises at least one of filter cotton, a filter membrane or a filter screen.

Further, as shown in fig. 4, the axial distance between the outer side edge of the dust baffle 2 and the first end of the filter cartridge 11 is greater than the axial distance between the inner side edge of the dust baffle 2 and the first end of the filter cartridge 11.

Specifically, the shape of the first shielding portion 22 relative to the axial cross section of the cylinder body 1 may be various, for example, the shape of the first shielding portion 22 relative to the axial cross section of the cylinder body 1 may include at least one of an inclined straight plate facing the first cylinder section 121, a curved plate facing the first cylinder section 121, and a straight plate perpendicular to the central axis of the cylinder body 1. The shape of the second shielding portion 23 with respect to the axial cross section of the cylinder body 1 may be various, for example, the shape of the second shielding portion 23 with respect to the axial cross section of the cylinder body 1 may include at least one of an inclined straight plate toward the first cylinder section 121, a curved plate toward the first cylinder section 121, and a straight plate perpendicular to the central axis of the cylinder body 1.

The dust guard 2 may be any combination of the first shielding portion 22 and the second shielding portion 23, for example, the dust guard 2 at least includes at least one of a combination of a straight plate facing a central axis of the cylinder 1 and a curved plate facing the first cylinder section 121, a combination of a straight plate facing a central axis of the cylinder 1 and an inclined straight plate of the first cylinder section 121, and a combination of an inclined straight plate facing the first cylinder section 121 and a curved plate.

As shown in fig. 4, in some embodiments, the shape of the dust-blocking plate 2 relative to the axial cross section of the barrel 1 is a combination of a straight plate perpendicular to the central axis of the barrel 1 and an inclined straight plate facing the first barrel section 121, the straight plate perpendicular to the central axis of the barrel 1 can block the environmental garbage rotating around the cyclone central barrel 12 from flying upwards, and the inclined straight plate facing the first barrel section 121 can block the environmental garbage flying upwards from bypassing the dust-blocking plate 2 and entering the first cavity, so as to further avoid the blocking of the filtering holes on the side wall of the filtering barrel 11.
