Referring to fig. 2 to 6, one end of the elastic member 11 is mounted on the body portion 10, and the other end thereof abuts against the ring member 50. The dirt cup 20 is ejected from the first position to the second position under the ejection of the resilient member 11. In this embodiment, referring to FIG. 5, in a first position and FIG. 6, in a second position, the ring 50 abuts the inner cylinder 22 of the dirt cup 20. When the dirt cup 20 is in the first position, the resilient member 11 is in a compressed state such that the annular member 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 elastic member 11, and abuts against the dirt cup 20 to move from the first position to the second position.

The dust cup 20 is movable relative to the air inlet duct 31, the air inlet duct 31 is integrated with the 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 dust cup 20 is locked to the main body 10 by the lock mechanism 41, 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 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 inner cylinder 22 of the dirt cup 20 and the air inlet duct 31 have an overlapping portion 211 when the first position and the second position and the first position move to the second position, so that dust in the dirt cup 20 is reduced or prevented from entering the air inlet duct 31 when the dirt cup 20 moves and is detached.

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 and the air intake duct 31 have an overlap 211 such that in the second position, dust in the primary dust zone is reduced or prevented from entering the air intake duct 31 from the primary dust zone 200. In the process from the first position to the second position, the overlapping portion 211 is gradually shortened.

Referring to fig. 3, the ring member 50 includes a first ring support 501, a connecting support 502, a second ring support 503, and a guide post 504, wherein the connecting support 502 connects the first ring support 501 and the second ring support 503, and the first ring support 501 abuts against the inner cylinder 22 of the dirt cup 20. The first and second

annular brackets

501 and 503, the connecting bracket 502, and the guide post 504 for receiving the elastic member 11 may be integrally formed.

The ring member 50 is fitted over the filter 30, and in this embodiment, referring to fig. 2 to 6, the dust scraping portion 53 is located on the second ring-shaped support 503 and is ejected together with the ring member 50, the dust scraping portion 53 abuts against the filter 30, and the dust scraping portion 53 scrapes the filter 30 by ejecting the ring member 50, so that large particles adsorbed on the filter holes are scraped down to the primary dust region 200 in the dust cup 20. Preferably, the dust scraper 53 has a swash plate shape, one end of which is mounted on the second ring bracket 503 and the other end of which abuts against the filter 30.

The first annular bracket 501 is provided with a first sealing member 511, and the first sealing member 511 abuts against the inner cylinder 22 of the dirt cup 20. A second seal 512 is also mounted on the first annular support 501. One side of the first sealing piece 511 abuts against the inner cylinder 22 of the dirt cup 20, the bottom surface of the first sealing piece 511 abuts against the outer wall of the air inlet duct 31, and when the ring-shaped piece 50 is not ejected, the second sealing piece 512 is located between the primary dust area 200 and the secondary dust area 300, specifically, located at the edge where the filter 30 is flush with the rotary duct 32, and the upper and lower top portions respectively abut against the edge where the filter 30 is flush with the rotary duct 32, so as to isolate the opening of the secondary dust area 300, which is located toward the filter 30 on the rotary duct 32, from the primary dust area 200.

The second annular bracket 503 is provided with a third sealing member 52, and the outer periphery of the third sealing member 52 abuts against the outer cylinder 21 of the dirt cup 20. Specifically, during the process of moving or ejecting the dust cup 20 from the first position to the second position relative to the air inlet duct 31, the first sealing member 511 abuts against the edge of the inner cylinder 22 of the dust cup 20 and the outer wall of the air inlet duct 31, so as to isolate the dust cup 20 from the outside air and isolate the dust cup 20 from the air inlet duct 31; the second sealing element 512 is positioned 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 third seal 52 seals against the inner wall of the outer housing 21 of the dirt cup 20 and the outer wall of the filter 30 from outside air entering the dirt cup 20.

When the ring member 50 is pushed or ejected, the ring member 50 moves together with the first sealing member 511 to push the dust 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 under the action of the pushing force or the ejecting force.

In this embodiment, the ring 50 abuts against the inner cylinder 22 of the dust cup 20, the length of the elastic member 11 that can be ejected is less than the length of the inner cylinder 22, and after the elastic member 11 ejects the dust cup 20, the inner cylinder of the dust cup 20 overlaps with the air inlet duct 31 of the cleaning device. That is, the overlapping portion 211 is always present and the first sealing member 511 is provided at the overlapping portion 211, so that the first sealing member 511 always seals the gap between the outer wall of the inner cylinder 22 and the outer wall of the air intake duct 31 during, after, and when the dirt cup 20 is ejected, to prevent fine dust from flying from the primary dust region 200 into the air intake duct 31, and the third sealing member 52 reduces or prevents fine dust from flying in the primary dust region 200. 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.

Preferably, the cleaning device further comprises a stop mechanism 42. 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 cleaning 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 elastic part 11, the air duct 31 of the cleaning device guides air carrying dust outside to the rotary duct 32, then the air enters the periphery of the filter 30 after rotating, after being filtered by the filter 30, large-particle dust is left in the primary dust area 200, and the air carrying fine particles enters the cyclone separation device in the main body part 10.

When the cleaning device is cleaned, the locking mechanism 41 is unlocked, the elastic element 11 ejects the annular element 50, the first annular support 501 of the annular element 50 abuts against the inner cylinder 22, so that the dust cup 20 is ejected from the first position to the second position, and the dust scraping part on the second annular support 503 abuts against the filter 30 to scrape dust to the primary dust area 200. In the second position, the overlapping portion 211 still exists between the inner cylinder 22 and the air inlet duct 31, and the first sealing element 511 seals the gap where the overlapping portion 211 exists, so that dust in the primary dust region 200 is reduced or prevented from entering the air inlet duct 31, and dust is effectively prevented from flying. Limiting mechanism 42 is pressed manually, so that limiting mechanism 42 slightly deforms, the limit of the sliding groove to the protruding part is removed, dust cup 20 is detached, garbage is dumped, and the dust cannot be lifted in the whole process.

The ejection assembly provided by the invention pushes the dust cup 20 to move while ejecting the ring-shaped piece, and ejects the dust cup 20 for a certain distance, so that the dust cup 20 is convenient to disassemble, and automatic dust scraping can be realized when the dust cup 20 is ejected; the ring-shaped piece 50 is skillfully designed, so that the dust cup 20 can be ejected and scraped without increasing the diameter of the cleaning device; the annular element 50 is provided with a sealing element, so that a primary dust area in the dust cup can be always in a sealing state in the process of ejecting the dust cup, and the influence on user experience and dust collection effect due to dust flying is reduced or avoided.

Example two:

referring to fig. 7-10, an ejection assembly of a cleaning device includes an elastic member 11, a ring member 50, and a dirt cup 20.

The elastic member 11 is mounted on the main body 10 of the cleaning device; the elastic member 11 is a compression spring, and when the dust cup 20 is attached to the main body 10, the elastic member 11 is in a compressed state. The ring 50 is provided inside with a guide post 504, and the elastic member 11 is extendable in the axial direction of the guide post 504 to eject the ring 50. The dirt cup 20 interferes with the ring member 50, ejecting the ring member 50 to move and push the abutting dirt cup 20 to eject to the detachable position after the elastic member 11 is released. . The annular member 50 is provided with a dust scraping portion 53, and the dust scraping portion 53 can automatically scrape dust while the elastic member 11 ejects out of the dust cup 20.

The cleaning device includes a main body 10, an air intake duct 31 for introducing external dust gas, and a filter 30 for filtering the dust gas. The dirt cup 20, the inlet duct 31 and the filter 30 are on the same axis. The air inlet duct 31 guides external dust and air to the periphery of the filter 10, the dirt cup 20 is mounted on the main body 10 through the locking mechanism 41, and the cyclone separating apparatus, the motor, etc. are mounted in the main body 10. A hollow interlayer is formed between the air inlet pipeline 31 and the filter 30 and is communicated with a channel for sucking airflow by the motor; the filter 30 is provided with filter holes through which the sucked air is primarily filtered to filter large particles of impurities.

Referring to fig. 7-10, one end of the elastic member 11 is mounted on the body 10, and the other end is positioned in the guide pillar 504 of the ring 50 to abut against the ring 50. The dirt cup 20 is ejected from the first position to the second position under the ejection of the resilient member 11. The ring 50 abuts the outer cylinder 21 of the dirt cup 20. When the dirt cup 20 is in the first position, the resilient member 11 is in a compressed state such that the annular member 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 elastic member 11, and abuts against the dirt cup 20 to move from the first position to the second position.

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 ring 50 abuts against the outer cylinder 21 or the inner cylinder 22 of the dirt cup 20. In this embodiment, the ring 50 abuts against the outer cylinder 21 of the dirt cup 20.

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 and the air intake duct 31 have an overlap 211 such that in the second position, dust within the primary dust zone is reduced or prevented from entering the air intake duct 31 from the primary dust zone 200. In the process from the first position to the second position, the overlapping portion 211 is gradually shortened.

Specifically, referring to fig. 8 to 10, the ring 50 is cylindrical, and the guide posts 504 are hidden inside the ring 50, so that the diameter of the whole cleaning device is not increased, and the cleaning device is suitable for an extremely small cleaning device. The cylindrical ring member 50 is sleeved on the periphery of the filter 30, the dust scraping part 53 is positioned on the inner ring of the ring member 50, the dust scraping part 53 is abutted against the filter 30, and the dust scraping part 53 scrapes the filter 30 by sliding the cylindrical ring member 50, so that large particles adsorbed on the filter holes are scraped into the dust cup 20.

The annular member 50 is provided with an abutting portion 54, the abutting portion 54 protrudes out of the annular member 50, and the abutting portion 54 abuts against the edge of the outer cylinder of the dirt cup 20. Preferably, to save space, a cylindrical ring 50 is located inside the housing of the body portion 10. After the dust cup 20 releases the locking mechanism, the elastic member in the compressed state ejects the ring member 50, the ring member 50 moves along the air inlet pipe 31 under the action of the elastic member 11, and the interference part 54 moves against the outer cylinder 21 of the dust cup 20, so that the dust cup 20 can be taken down conveniently. In this process, the dust scraping part 53 on the ring member 50 scrapes the outer wall of the filter 30, thereby scraping large particles adsorbed to the filter holes into the dirt cup 20.

In addition, the length of the inner cylinder 22 is not less than the distance that the elastic element 11 pushes the dust scraping part 53 to move, that is, the length that the elastic element 11 can eject is less than the length of the inner cylinder 22, and after the elastic element 11 ejects the dust cup 20, an overlapping part exists between the inner cylinder of the dust cup 20 and the air inlet pipeline 31 of the cleaning device. After the elastic member 11 pushes the dust scraping portion 53 and the dust cup 20 out, the inner cylinder 22 still contacts with the air inlet pipe 31 to prevent the scraped dust from leaking out from the gap at the bottom of the dust cup 20.

When the cleaning 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 elastic piece 11, the air carrying dust outside is guided by the air inlet pipeline 31 of the cleaning device to the periphery of the filter 30, after being filtered by the filter 30, the large-particle dust enters the first-stage dust area 200, and the air carrying fine particles enters the cyclone separation device in the main body part 10.

When the cleaning device is cleaned, the locking mechanism 41 is unlocked, the elastic member 11 ejects the ring member 50, the abutting part 54 of the ring member 50 abuts against the outer cylinder 21, so that the dust cup 20 is ejected, and the ejected dust scraping part 53 abuts against the filter 30 together to scrape dust to the primary dust area 200.

The ejection assembly provided by the invention pushes the dust cup 20 to move while ejecting the ring-shaped piece, the dust cup 20 is ejected for a certain distance, the dust cup 20 is convenient to disassemble, and the dust scraping part 53 clings to the filter 30 to scrape dust to the primary dust area 200 when the dust cup 20 is ejected, so that automatic dust scraping is realized; and the ring-shaped piece 50 is skillfully designed, so that the dust cup 20 can be ejected and scraped without increasing the diameter of the cleaning device. In addition, in the process that the elastic element 11 ejects the dust cup 20 out, an overlapping part exists between the inner cylinder 22 of the dust cup 20 and the air inlet pipeline 31, and the primary dust area 200 in the dust cup is always in a sealed state, so that the dust flying is reduced or avoided, and the user experience and the dust collection effect are influenced.

In addition, the invention also provides a cleaning device, which comprises the ejection component of the cleaning device in the first embodiment or the second embodiment.

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.
