Preferably, the filter 30 is flush with the edge of the rotary duct 32 with a separation layer therebetween, dust and air on the outer circumference of the filter 30 is filtered by the filter 30, and then enters the cyclone separating apparatus in the main body 10 through the separation between the filter 30 and the rotary duct 32, and the separated fine dust enters the secondary dust area 300.

First seal 511, second seal 512, and third seal 52 are mounted on ring 50. During ejection of the ring 50, the first sealing member 511 abuts against the edge of the inner cylinder 22 of the dirt cup 20 and the outer wall of the air inlet duct 31, and the third sealing member 52 abuts against the inner wall of the outer cylinder 21 of the dirt cup 20 and the outer wall of the filter 30. Specifically, the first and second sealing members 511 and 512 are sealing rings, each of which generally includes two side surfaces and upper and lower top portions, one side surface of the first sealing member 511 abuts against the inner cylinder 22 of the dirt cup 20, the bottom surface of the first sealing member 511 abuts against the outer wall of the air inlet duct 31, the second sealing member 512 is located at an edge of the filter 30 which is flush with the rotary duct 32 when the ring member 50 is not ejected, and the upper and lower top portions respectively abut against the edge of the filter 30 which is flush with the rotary duct 32, so as to isolate the opening of the secondary dirt area 300, which is located on the rotary duct 32 and faces the filter 30, from the primary dirt area 200.

The upper top of the third sealing member 52 abuts against the inner wall of the outer tub 21 of the dirt cup 20, and the lower top of the third sealing member 52 abuts against the outer wall of the filter 30.

The ring 50 includes a first annular support 501, a connecting support 502 and a second annular support 503. The connecting bracket 502 connects the first annular bracket 501 and the second annular bracket 503, the first annular bracket 501, the second annular bracket 503 and the connecting bracket 502 may be integrally formed, the first seal 511 and the second seal 512 are mounted on the first annular bracket 501, and the third seal 52 is mounted on the second annular bracket 503. The ring 50 is provided with a guide post 504, the guide post 504 receives the ejector 11, and the ring 50 moves and pushes the abutting dirt cup 20 to move under the ejection action of the ejector. During the movement of the ejection ring 50 of the ejection device and pushing the dust cup 20 against the ejection ring, the first sealing element 511 can be tightly attached to the edge of the inner cylinder 22 of the dust cup, so that a tight sealing effect is achieved.

Referring to fig. 7, when the cleaning device is in a dust collecting state after the dust cup 20 is installed, two side surfaces of the first sealing member 511 respectively abut against the edge of the dust cup 20 (or the inner cylinder 22), and the bottom surface of the first sealing member 511 abuts against the air inlet duct 31. The upper and lower tops of the second sealing member 512 respectively abut against the edge of the filter 30 flush with the rotary duct 32, in other words, the filter 30 flush with the edge of the rotary duct 32, and the second sealing member 512 abuts against the edge flush therebetween, so as to isolate the primary dust zone 200 from the secondary dust zone 300, prevent the air flow between the primary dust zone 200 and the secondary dust zone 300 from being series-connected, and affect the dust suction effect, and prevent the dust gas not filtered by the filter 30 from directly blocking at the cyclone separating device at the end of the main body 10 from the secondary dust zone 300, and affect the subsequent cyclone separation, the efficiency of the HEPA filtration, and damage other components in the main body 10.

Specifically, in the present invention, the external air enters the rotary duct 32 through the air inlet duct 31 to rotate, and then enters the periphery of the filter 30, the large particle dust filtered by the filter holes of the filter 30 enters the primary dust region 200 of the dust cup 20, the air with the fine particles enters the cyclone separating device in the main body 10 from the space between the filter 30 and the rotary duct 32, and the fine dust separated by the cyclone separating device enters the secondary dust region 300. A primary dust area 200 is formed between the inner cylinder and the outer cylinder of the dust cup 20 in the invention, and stores large particle dust after being filtered and dust gas without being filtered, a secondary dust area 300 is arranged in the rotary pipeline 32, the dust gas filtered by the filter 30 enters the cyclone separation device in the main body part 10 through the interval between the filter 30 and the rotary pipeline 32, and the dust separated by the cyclone separation device enters the secondary dust area 300. If the primary dust area 200 is communicated with the secondary dust area 300, the dust gas in the primary dust area 200, which is not filtered, directly enters the secondary dust area 300, so that the dust gas flows in series, the dust gas cannot normally enter the cyclone separation device after being filtered by the filter 30, the dust collection effect is affected, and the dust gas, which is not filtered, directly enters the secondary dust area 300 from the primary dust area 200 and blocks the surface of the cyclone separation device, so that the subsequent cyclone separation efficiency and the HEPA filtration efficiency are affected, and other components in the main body 10 are damaged. Therefore, it is necessary to provide a second sealing member 512 between the primary dust area 200 and the secondary dust area 300 to form a blocking structure of the primary dust area 200 and the secondary dust area 300.

The first sealing element 511, the second sealing element 512 and the third sealing element 52 are soft sealing elements, and the minimum inner diameter of the first sealing element 511 is smaller than the maximum inner diameter of the air inlet duct 31, so that the first sealing element 511 can abut against the outer wall of the air inlet duct 31 during the movement of the dirt cup 20 to seal the gap between the dirt cup 20 and the air inlet duct 31; the maximum outer diameter of the second seal 512 is slightly larger than the distance between the filter 30 and the rotary pipe 32, so that the second seal 512 can be tightly sealed between the two; the minimum inner diameter of the third seal 52 is smaller than the maximum inner diameter of the filter 30 so that the third seal 52 interferes with the outer wall of the filter 30.

Referring to fig. 5, the first sealing member 511 is provided with an abutting surface (not shown) which abuts against the inner cylinder 22 of the dirt cup 20. The first annular bracket 501 is provided with a guide surface inclined in a direction toward the primary dust region 200 in the dust cup 20. The inclined guide surface guides dust entering the primary dust area 200. In other embodiments, the guide surface is angled in a direction toward the primary dirt region 200 in the dirt cup 20 to save material on the entire ring.

When the cleaning device is in a dust collection state, the first sealing element 511 abuts against the edge of the inner cylinder 22 of the dust cup 20 and the outer wall of the air inlet pipeline 31 to isolate the outside from the primary dust area 200, prevent outside air from entering the dust cup 20 from a gap between the inner cylinder 22 and the air inlet pipeline 31 and prevent dust in the dust cup 20 from flying to the outside and the air inlet pipeline 31; the second sealing element 512 is positioned at the opening of the secondary dust area 300, the edge of the second sealing element 512 abutting against the filter 30 and flush with the air inlet pipe 31 (or the rotary pipe 32 connected with the air inlet pipe 31) seals the opening of the secondary dust area 300 on the rotary pipe 32 and arranged towards the filter 30, and separates the primary dust area 200 from the secondary dust area 300; the third sealing member 52 interferes with the inner wall of the outer tub 21 and the outer wall of the filter 30, preventing the external air from entering the dirt cup 20 from the gap between the inner wall of the outer tub 21 and the filter 30. When the ring member 50 is pushed or ejected, the ring member 50 moves together with the first sealing member 511 to push the dirt cup 20 to move along the air inlet duct 31, and the first sealing member 511 seals a gap between the outer wall of the inner cylinder 22 and the outer wall of the air inlet duct 31 at all times under the pushing or ejecting force to prevent dust from flying out of the primary dust region 200.

The dirt cup 20 includes an outer cylinder 21 and an inner cylinder 22, and a primary dirt area 200 is formed between the outer cylinder 21 and the inner cylinder 22.

The air intake duct 31 is coaxial with the main body 10. Dust is guided from the air inlet duct 31 into the cleaning device. A rotary duct 32 is integrally formed with or fixedly connected to the air inlet duct 31, and preferably, the rotary duct 32 is a spiral duct inside. The air intake duct 31 guides the dust air to the rotation duct 32 to rotate.

The rotary pipe 32 is provided with an inner wall and an outer wall, the inner wall is spiral, external air flows enter the spiral pipe formed by the inner wall, the outer wall is integrally formed at the periphery of the inner wall, and the area between the inner wall and the outer wall is a secondary dust area 300. The inner wall forms a rotary conduit directly communicating to the outer periphery of the filter 30. The secondary dust area 300 is used for storing the fine dust separated by the cyclone separating apparatus, and an opening (not shown) of the secondary dust area 300 is formed on an outer wall thereof.

The filter 30 is a ring-shaped filter structure, and is a filter 30 for filtering dust. The annular filter 30 is sleeved outside the rotary pipeline 32, the rotary pipeline 32 is provided with a first outlet, the filter 30 is provided with a second outlet, the second outlet is larger than the first outlet, the filter 30 is provided with a filter hole, the first outlet is opposite to the second outlet, dust air passing through the rotary pipeline 32 enters the periphery of the filter 30 after rotating through the rotary pipeline 32, large-particle dust enters the primary dust area 200 of the dust cup 20 after being filtered through the filter hole of the filter 30, and air carrying fine particles enters the cyclone separation device in the main body part 10.

Preferably, the filter 30 is flush with the edge of the rotating pipe 32, with a barrier between them,

the dust gas on the outer circumference of the filter 30 is filtered by the filter 30, and then enters the cyclone separating apparatus in the main body 10 through the interval between the filter 30 and the rotary duct 32, and the separated fine dust enters the secondary dust area 300.

Dirt cup 20 also has an end wall 23. The end wall 23 connects the outer cylinder 21 and the inner cylinder 22 smoothly, so that a primary dust area 200 is formed between the outer cylinder 21 and the inner cylinder 22. In other embodiments, the end wall 23 may not be included, and the outer cylinder 21 is bent to form the inner cylinder 22, and the primary dust region 200 is located between the two.

During movement or ejection of the dirt cup 20 from the first position to the second position relative to the air intake duct 31, the inner drum 22 is adjacent to the air intake duct 31 and moves relative to the air intake duct 31. The first sealing member 511 is installed at the end of the inner cylinder 22, and abuts against the outer wall of the air inlet duct 31; the third seal 52 abuts the inner wall of the outer cartridge 21 and the filter 30.

The dust cup 20 is movable relative to the air inlet duct 31 in the vicinity of the air inlet duct 31, the air inlet duct 31 is integrated with a rotary duct 32, and the rotary duct 32 is mounted on the main body 10. The dirt cup 20 is ejected from a first position to a second position relative to the air intake duct 31. The first position is a position where the dirt cup 20 is locked to the main body 10, and the cleaning apparatus is in a usable state in the first position. The second position is the farthest distance that the dirt cup 20 is pushed out or ejected with respect to the air intake duct 31, and the second position is a position where the dirt cup 20 is detachable from the air intake duct 31.

The cup wall of the dust cup 20 and the air inlet duct 31 have an overlapping portion 211 during the first position and the second position and the process of moving the first position to the second position, so that the dust cup 20 can reduce or prevent the dust in the dust cup 20 from leaking out during the moving process and the disassembling process.

In the first position, the inner cartridge 22 surrounds the air inlet duct 31. During movement of the dirt cup 20 from the first position to the second position, the inner cylinder 22 moves against the outer wall of the air inlet duct 31. In the second position, the inner barrel 22 has an overlap 211 with the air intake duct 31 such that in the second position, entry into the air intake duct 31 from the primary dirt region 200 is reduced or avoided. In both the first position and the second position, the inner cylinder 22 and the intake duct 31 have an overlapping portion 211, and the overlapping portion 211 gradually shortens in the process from the first position to the second position.

With the dirt cup 20 in the first position, the ejector 11 is in a compressed state such that the ring 50 is always in a tendency to move forward. When the locking mechanism 41 is unlocked, the ring member 50 moves along the air inlet duct 31 under the action of the ejector 11, abutting against the dirt cup 20 and moving from the first position to the second position.

When the ring 50 is pushed or ejected, the first sealing piece 511 abuts against the inner cylinder 22 of the dust cup 20, the ring 50 moves together with the first sealing piece 511 to push the dust cup 20 to move along the air inlet duct 31, and the first sealing piece 511 seals the space between the outer wall of the inner cylinder 22 and the outer wall of the air inlet duct 31 under the action of the pushing force or the ejecting force.

The ejector 11 can eject the dirt cup 20 a distance less than the length of the inner cylinder 22. The ejection device 11 is a compression spring, the length of the ejection device 11 which can be recovered after being compressed is smaller than the length of the inner cylinder 22, so that the ejection device 11 ejects the dust cup 20 to move from the first position to the second position, the dust cup 20 still has an overlapping part 211 with the air inlet pipeline 31 at the second position, and a first sealing ring 511 is arranged at the overlapping part 211, so that the first sealing ring 511 always seals the interval between the outer wall of the inner cylinder 22 and the outer wall of the air inlet pipeline 31 during the ejection process, after being ejected and when being detached of the dust cup 20, and the outside is isolated from the primary dust area 200.

Preferably, the cleaning device further comprises a locking mechanism 41 and a limiting mechanism 42. The locking mechanism 41 is a snap structure, a hook end of the snap structure is mounted on the housing of the main body 10, and another hook end of the snap structure is mounted on the outer wall of the dust cup 20. When the dust cup 20 is at the first position, the dust cup 20 is locked by the locking mechanism 41, and when the dust cup 20 is unlocked by the locking mechanism 41, the dust cup 20 is ejected to the second position by the ejector 11.

The limiting mechanism 42 is installed on the dust cup 20, a protruding part protrudes from the limiting mechanism 42 in a direction departing from the dust cup 20, and a sliding groove is arranged below the main body part 10. The limiting mechanism 42 can slide in the sliding groove below the main body 10, when the main body 10 moves to the first position, the protrusion on the limiting mechanism 42 sinks into the slot in the sliding groove, and when the dust cup 20 is separated from the locking of the locking mechanism 41, the protrusion of the limiting mechanism 42 is separated from the slot and slides to the second position along the sliding groove. When the dust cup 20 is in the second position, the end of the chute limits the protrusion, thereby limiting the dust cup 20 from automatically falling off. That is, when the dust cup 20 is at the second position, the dust cup 20 is limited by the limiting mechanism 42 to prevent the dust cup 20 from automatically falling off.

When the cyclone dust separating device is used, the dust cup 20 is buckled on the main body part 10 through the locking mechanism 41, the dust cup 20 is in a tendency of being ejected under the compression action of the ejection device 11, the air inlet pipeline 31 of the cleaning device guides air carrying dust outside to the rotary pipeline 32 to rotate and then to enter the periphery of the filter 30, after being filtered by the filter 30, large-particle dust enters the primary dust region 200, and air carrying fine particles enters the cyclone separating device in the main body part 10.

When the dust in the cleaning device is dumped, the opening of the air inlet pipeline 31 faces downwards, the dust in the primary dust area 200 moves towards the direction of the end wall 23, the locking of the locking mechanism 41 is released, the ejection device 11 ejects the dust cup 20 from the first position to the second position, in the second position, the overlapping part 211 still exists between the inner cylinder 22 and the air inlet pipeline 31, the first sealing piece 511 seals the gap existing in the overlapping part 211, the dust in the primary dust area 200 is reduced or prevented from entering the air inlet pipeline 31, and dust raising is effectively prevented. Limiting mechanism 42 is pressed manually, so that limiting mechanism 42 slightly deforms, the limitation of the sliding groove to the protruding part is removed, dust cup 20 is detached, garbage is dumped, and the whole process is reduced or prevented from raising dust.

According to the invention, a first sealing element 511 is arranged between the inner cylinder of the dust cup and the air inlet pipeline, a second sealing element 512 is arranged between the secondary dust area 300 of the rotary pipeline 32 and the primary dust area 200, after the dust cup is installed, namely when the cleaning device is in a dust collection state, the first sealing element 511 seals a gap between the inner cylinder 22 of the dust cup and the air inlet pipeline 31 to isolate the outside from the primary dust area 200, in the process of guiding dust by the air inlet pipeline, unfiltered dust gas is prevented from entering the primary dust area 200 to influence the dust collection effect, and when the ejection device ejects the ring-shaped element 50 to move and pushes the abutted dust cup to move, the first sealing element 511 can be more tightly attached to the edge of the inner cylinder of the dust cup 20, so that tight sealing is realized and dust in the primary dust area 200 is prevented from flying; when the cleaning device is in a dust collection state, the second sealing element 512 isolates the secondary dust area 300 in the rotary pipeline from the primary dust area 200 in the dust cup, so that unfiltered dust is prevented from entering the main body part from the secondary dust area 300, and the disordered streaming of air is caused during dust collection, and the dust collection effect is influenced. The present invention further provides a third sealing member 52 between the inner wall of the outer tub 21 and the outer wall of the filter 30, which can prevent the outside air at the other end of the dust cup from entering the dust cup.

The above is only one embodiment of the present invention, and any other modifications based on the concept of the present invention are considered as the protection scope of the present invention.
