DETAILED DESCRIPTION

[0023] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0024] Reference Figure 1-Figure 5 As shown, the present invention discloses a retractable dust cup, including a first shell 10 and a second shell 20, the first shell 10 and the second shell 20 are arranged in a sleeve-coordinated manner to form a retractable structure, and the inner cavities of the first shell 10 and the second shell 20 are connected through. Since the dust cup is a retractable structure, its volume can be enlarged, and thus more dust can be stored. When not in use, the dust cup can be retracted, thereby reducing the volume, making it easier to carry and store. A limiting mechanism is provided between the first shell 10 and the second shell 20, and the limiting mechanism includes a shortening limiting assembly and an extending limiting assembly. The shortening limiting assembly can limit the dust cup in a shortened state, thereby controlling the minimum stroke of the dust cup; the extending limiting assembly can limit the maximum stroke of the dust cup in an extended state.

[0025] Preferably, the first shell 10 is sleeved on the second shell 20. The shortening limit assembly includes a protrusion 21, which is arranged on the second shell 20 to limit the minimum stroke of the telescopic structure. When the first shell 10 and the second shell 20 move relative to each other, that is, when the dust cup is retracted, the protrusion 21 on the second shell 20 abuts against the first shell 10, so that it cannot continue to move toward the first shell 10.

[0026] The extension limit assembly includes a limit convex portion 11, a long groove 26 is provided on the second shell 20, and the limit convex portion 11 is arranged on the first shell 10. The limit convex portion 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 portion 11 can only slide in the long groove 26, thereby limiting the maximum stroke of the dust cup in the retracted state. When the dust cup is extended, the limit convex portion 11 on the first shell 10 will hook the second shell 20, that is, hook the second shell 20 by hooking the groove wall of the long groove 26, so that the dust cup will not be infinitely extended, and the first shell 10 and the second shell 20 will not be separated.

[0027] The present invention also includes a locking mechanism, the locking structure includes 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 includes a locking area and an unlocking area; when the telescopic structure is in the maximum extension state, the locking plate 23 is located in the locking area; when the telescopic structure is not in the maximum extension state, the locking plate 23 is located in the unlocking area. When the dust cup is extended to the maximum length, that is, the volume in the dust cup is the largest at this time, and in order to ensure the stability of the dust cup, the locking mechanism will lock the first shell 10 and the second shell 20, so that the dust cup will not shrink.

[0028] Specifically, a groove is provided on the first shell 10, and a button 24 is provided in the groove, and the button 24 is fixedly connected to the locking plate 23. One end of the locking plate 23 is fixed to the second shell 20, and the other end of the locking plate 23 is arranged toward the first shell 10. When the telescopic structure is in the maximum extension state, the other end of the locking plate 23 abuts 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 located inside the first shell 10. Then the second shell 20 can move relative to the first shell 10, thereby shrinking the dust cup. There are two locking mechanisms in the present invention, and the two locking mechanisms are symmetrically arranged relative to the second shell 20. A limit plate 27 is also provided on the second shell 20, and the limit plate 27 is located on one side of the locking plate 23. 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 being excessively bent. When the dust cup is in the retracted state, the first shell 10 and the second shell 20 can be grasped and pulled apart to the maximum extension state, at which time the unfixed end of the locking plate 23 opens outward under the tension of the locking plate 23 itself, and the locking plate 23 moves to the unlocking area, where the locking plate 23 abuts against the wall of the first shell 10, and the first shell 10 and the second shell 20 are relatively fixed. When the dust cup needs to be retracted, the button 24 is pressed to move the unfixed end of the locking plate 23 into the dust cup, that is, the locking plate 23 moves to the unlocking area, at which time the second shell 20 can move relative to the first shell 10, and the dust cup can be retracted.

[0029] A separator 40 is arranged in the first shell 10, and a brush 41 is fixedly arranged on the inner wall of the second shell 20, and the brush 41 is arranged toward the outer wall of the separator 40 and the brush head of the brush 41 abuts against the separator 40. Since the second shell 20 and the first shell 10 can move relative to each other, the brush 41 will clean the surface of the separator 40 during the extension or shortening of the dust cup, which is convenient and practical. The dust of the separator 40 is cleaned by the brush 41 and falls into the dust chamber, which is convenient for dumping. As is known to all, the separator 40 is used for a long time, and its surface is covered with dust, which sometimes affects the dust and gas separation efficiency. At present, the separator 40 on the market is extremely troublesome to clean, and when cleaning, the dust cup needs to be opened, and the surface of the separator 40 needs to be brushed with a brush, or the surface of the separator 40 needs to be wiped with a paper towel, which is inconvenient to clean, and the dust is splashed everywhere, which is extremely inconvenient. The brush in the present invention can clean the separator 40 when the dust cup is closed, and the dust will not fly around, and the dust after cleaning is still in the dust cup, which is convenient for dumping. A cover 25 is also provided at the end of the second shell 20. The dust in the dust cup can be poured out by opening the cover 25.

[0030] The brush 41 in the present invention is an arc-shaped structure, a circular structure or a flat plate structure. The brush 41 is arranged around the separator 40, so as to facilitate cleaning of the separator 40.

[0031] A dust suction pipe 30 is also provided in the second housing 20, and a dust suction channel 31 matching the dust suction pipe 30 is provided in the first housing 10. When the second housing 20 is telescopic relative to the first housing 10, the dust suction pipe 30 can also be telescopic relative to the dust suction channel 31, so that the device can have a larger volume. The end of the dust suction pipe 30 can be connected to various suction heads.

[0032] A baffle 32 is provided in the dust suction passage 31, and the baffle 32 is connected to the inner wall of the dust suction passage 31 through a torsion spring. Under the suction force of the vacuum cleaner, the baffle is opened. The baffle 32 can also be a rubber piece, which is elastically deformed and opened by the suction force of the vacuum cleaner.

[0033] The present invention also discloses a vacuum cleaner, comprising the above-mentioned retractable dust cup. Figure 5 , which is a schematic diagram of the structure of the vacuum cleaner of the present invention. The vacuum cleaner is a handheld vacuum cleaner, comprising the above-mentioned retractable dust cup and a handle 50. The vacuum cleaner is easy to store, has a large dust cup volume, and is easy to use.

[0034] The above-described embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or changes made by those skilled in the art based on the present invention are within the protection scope of the present invention. The protection scope of the present invention shall be subject to the claims.
