Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

Referring to fig. 1-5, the utility model discloses a scalable dirt cup, including first casing 10 and second casing 20, first casing 10 cooperates the cover with second casing 20 to establish and forms extending structure, and first casing 10 is through connection with the inner chamber of second casing 20. Because this dirt cup is extending structure, its volume can grow, and then can store more dust. When not in use, the dust cup can be retracted, thereby reducing the volume and being convenient for carrying and storage. A limiting mechanism is arranged between the first shell 10 and the second shell 20, and the limiting mechanism comprises a shortening limiting component and an extending limiting component. The shortening limiting assembly can limit the dust cup in a shortened state, so that the minimum stroke of the dust cup is controlled; the extension limiting assembly can limit the maximum travel of the dust cup in an extended state.

Preferably, the first housing 10 is fitted over the second housing 20. And the shortening stop assembly includes a boss 21, and the boss 21 is provided on the second housing 20 to define a minimum stroke of the telescopic structure. When the first housing 10 and the second housing 20 move relatively, i.e., the dirt cup contracts, the projection 21 on the second housing 20 abuts the first housing 10 so that it cannot move further toward the first housing 10.

The extension limiting assembly comprises a limiting convex part 11, a long groove 26 is formed in the second shell 20, the limiting convex part 11 is arranged on the first shell 10, and the limiting convex part 11 is arranged in the long groove 26 to limit the maximum stroke of the telescopic structure. Due to the existence of the long groove 26, the limit convex part 11 can only slide in the long groove 26, thereby limiting the maximum stroke of the dust cup in a contraction state. When the dust cup extends, the limiting protrusion 11 on the first housing 10 hooks the second housing 20, i.e. hooks the second housing 20 by hooking the slot wall of the elongated slot 26, so that the dust cup will not extend infinitely, and the first housing 10 will not separate from the second housing 20.

The utility model also comprises a locking mechanism, the locking structure comprises a locking installation groove 22 and a locking plate 23, the locking plate 23 is arranged on the second shell 20, the locking installation groove 22 is arranged on the first shell 10, and the locking installation groove 22 comprises a locking area and an unlocking area; when the telescopic structure is in the maximum extension state, the locking plate 23 is positioned in the locking area; when the telescopic structure is not in the maximum extension state, the locking plate 23 is located in the unlocking zone. When the dust cup is extended to the maximum length, i.e. when the volume in the dust cup is the maximum, in order to ensure the stability of the dust cup, the locking mechanism locks the first housing 10 and the second housing 20, so that the dust cup does not shrink.

Specifically, a groove is formed in the first housing 10, a button 24 is disposed in the groove, and the button 24 is fixedly connected to the locking plate 23. One end of the lock plate 23 is fixed to the second housing 20, and the other end of the lock plate 23 is disposed toward the first housing 10. When the telescopic structure is in the maximum extension state, the other end of the locking plate 23 abuts against the first shell 10; when the telescopic structure is not in the maximum extension state, the button 24 is pressed, and the other end of the locking plate 23 is positioned inside the first housing 10. The second housing 20 can be moved relative to the first housing 10 to retract the dirt cup. The utility model provides a locking mechanism has two, and two locking mechanisms set up for second casing 20 symmetries. A limit plate 27 is further disposed on the second housing 20, the limit plate 27 is located on one side of the locking plate 23, and when the button 24 is pressed, the limit plate 27 limits the movement of the locking plate 23 to prevent the locking plate 23 from bending excessively. When the dust cup is in a contracted state, the first casing 10 and the second casing 20 can be grasped and pulled to be in a maximum extension state, at the moment, the unfixed end of the locking plate 23 is outwards opened under the action of the tension of the locking plate 23, the locking plate 23 moves to an unlocking area, the locking plate 23 can be abutted to the wall surface of the first casing 10, and the first casing 10 and the second casing 20 are relatively fixed. When the dust cup needs to be retracted, the key 24 is pressed, so that the unfixed end of the locking plate 23 moves into the dust cup, that is, the locking plate 23 moves to the unlocking area, at this time, the second housing 20 can move relative to the first housing 10, and the dust cup can be retracted.

A separator 40 is provided in the first housing 10, a brush 41 is fixedly provided on an inner wall of the second housing 20, the brush 41 is provided toward an outer wall of the separator 40, and a brush head of the brush 41 abuts against the separator 40. Because the second housing 20 and the first housing 10 can move relatively, the brush 41 can clean the surface of the separator 40 during the extension or contraction of the dust cup, which is convenient and practical. The dust in the separator 40 is cleaned by the brush 41 and falls into the dust chamber, so that the dust can be poured conveniently. It is known that the separator 40 is used for a long time and the surface of the separator is covered with dust, which sometimes affects the dust-gas separation efficiency. At present, the cleaning of the separator 40 in the market is very troublesome, and during the cleaning, the dust cup needs to be opened, the surface of the separator 40 is brushed by a brush, or the surface of the separator 40 is wiped by a paper towel, so that the cleaning is inconvenient, and the dust splashes around, which is very inconvenient. And the utility model provides a brush can clear up separator 40 under the dirt cup closed condition, and the dust can not fly in disorder everywhere, and the dust after the clearance is still in the dirt cup, is convenient for empty. The end of the second housing 20 is further provided with a cover 25, and when the cover 25 is opened, the dust in the dust cup can be poured out.

The brush 41 of the present invention has a circular arc structure, a circular structure or a flat structure. A brush 41 is provided around the separator 40 to facilitate cleaning of the separator 40.

A dust suction pipe 30 is further provided in the second housing 20, and a dust suction passage 31 is provided in the first housing 10 to be engaged with the dust suction pipe 30. The suction pipe 30 is also retractable with respect to the suction passage 31 during the telescopic action of the second housing 20 with respect to the first housing 10, which ensures a larger capacity of the device. And the end of the suction pipe 30 can be connected to various suction heads.

A baffle 32 is arranged in the dust suction channel 31, and the baffle 32 is connected with the inner wall of the dust suction channel 31 through a torsion spring. Under the action of the suction force of the dust collector, the baffle is opened. The baffle 32 may also be a rubber member that is elastically deformed to open by suction from the cleaner.

The utility model also discloses a dust catcher, including foretell telescopic dirt cup. As shown in fig. 5, it is a schematic structural view of the vacuum cleaner of the present invention. This dust catcher is hand-held type dust catcher, including foretell scalable dirt cup and handle 50, this dust catcher is convenient for accomodate, and the dirt cup is bulky, convenient to use.

The above-mentioned embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto.
