DETAILED DESCRIPTION

[0028] 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.

[0029] Reference Figure 1-Figure 8 As shown, the present invention discloses a vacuum cleaner that is easy to store, including a vacuum cleaner body 80 and a charging stand.

[0030] The vacuum cleaner body includes a retractable dust cup, and the dust cup includes a first shell 10 and a second shell 20. The first shell 10 and the second shell 20 are arranged in a telescopic structure, and the inner cavities of the first shell 10 and the second shell 20 are connected through. Since the dust cup is a telescopic structure, its volume can be enlarged, and more dust can be stored. When not in use, the dust cup can be retracted to reduce the volume, which is convenient for carrying and storage. A limiting mechanism is provided between the first shell 10 and the second shell 20, and the limiting mechanism includes a shortening limiting component and an extending limiting component. The shortening limiting component can limit the dust cup in the shortened state, thereby controlling the minimum stroke of the dust cup; the extending limiting component can limit the maximum stroke of the dust cup in the extended state.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] The brush 41 in the present invention is an arc-shaped structure or a circular structure. The brush 41 is arranged around the separator 40, so as to facilitate cleaning of the separator 40.

[0037] 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. A baffle 32 is provided in the dust suction channel 31, and the baffle 32 is connected to the inner wall of the dust suction channel 31 through a torsion spring. 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.

[0038] The charging stand includes a base 60 and a bracket 70 for fixing the vacuum cleaner body 80. The base 60 is provided with a charging connector 61 that matches the vacuum cleaner. The bracket 70 is hinged to the base 60 and the bracket 70 rotates around the base 60. When the bracket 70 rotates to fit with the base 60, the charging port 81 on the vacuum cleaner body 80 is connected to the charging connector 61. Rotate the bracket 70 so that the bracket 70 and the base 60 form a certain angle, place the vacuum cleaner body 80 on the bracket 70 and fix it, and then rotate the bracket 70 to fit with the base 60. At this time, the charging port 81 on the vacuum cleaner body 80 is connected to the charging connector 61, and the vacuum cleaner charging stand can charge the vacuum cleaner.

[0039] The base 60 is provided with a bracket 70 receiving groove 64, and the bracket 70 can rotate around the base 60 into the bracket 70 receiving groove 64. In this way, the vacuum cleaner charger is smaller in size and more compact in structure. The base 60 stores the vacuum cleaner body 80 like a box.

[0040] A flip mechanism for flipping up the bracket 70 is provided between the base 60 and the bracket 70. The flip mechanism can flip up the bracket 70, making it convenient to install the vacuum cleaner body 80 on the bracket 70. The present invention has two implementation methods: when the gravity of the vacuum cleaner body 80 is large, the elastic force of the flip mechanism can be overcome, and the bracket 70 can be pressed to fit with the base 60, so that the vacuum cleaner body 80 can be charged; when the gravity of the vacuum cleaner body 80 is small, that is, the vacuum cleaner body 80 is not enough to press the bracket 70 to fit with the base 60, a locking mechanism can be provided at this time, and the locking mechanism fits and fixes the bracket 70 and the base 60.

[0041] In one embodiment, the flipping mechanism includes a torsion spring 90, which is arranged at the hinge of the bracket 70 and the base 60. Under the action of the torsion spring 90, the bracket 70 can be separated from the base 60. In another embodiment, the flipping structure includes a torsion spring 90 and a push plate 91, which is arranged between the bracket 70 and the base 60, and the push plate 91 is hinged to the bracket 70, and the torsion spring 90 is arranged at the hinge of the push plate 91 and the bracket 70. In this embodiment, the push plate 91 can drive the bracket 70 to bounce upward. Compared with the former, this arrangement method uses the principle of leverage, which makes it easier to bounce the bracket 70 and has greater elasticity.

[0042] The locking mechanism includes a button 62 and a hook 63. The button 62 cooperates with the hook 63 to move the hook 63, and the hook 63 is used to lock the bracket 70 on the base 60. There are at least three ways to implement the hook 63 to lock the bracket 70 on the base 60: first, a groove body that cooperates with the hook 63 can be provided on the vacuum cleaner body 80. When the bracket 70 is rotated to fit with the base 60, the hook 63 clamps the groove body on the vacuum cleaner body 80, so that the bracket 70 is fixed on the base 60, and the vacuum cleaner body 80 is also fixed on the base 60 at this time; second, a tongue extending toward the hook 63 can be provided on the bracket 70. When the bracket 70 is rotated to fit with the base 60, the hook 63 clamps the groove body on the vacuum cleaner body 80, so that the bracket 70 is fixed on the base 60, and the vacuum cleaner body 80 is also fixed on the base 60; 0 is rotated to fit with the base 60, the hook 63 clamps the tongue; thirdly, the hook 63 may include a first hook and a second hook, a groove body matching the first hook is provided on the vacuum cleaner body 80, and a tongue extending toward the second hook is provided on the bracket 70. When the bracket 70 is rotated to fit with the base 60, the hook 63 can lock the bracket 70 and the vacuum cleaner body 80 at the same time. In this way, the structure of the device is more stable and the vacuum cleaner body 80 is fixed more firmly.

[0043] The bracket 70 is provided with a first placement groove 71 for placing the vacuum cleaner body 80. The first placement groove 71 is cylindrical, and the vacuum cleaner body 80 is inserted into the first placement groove 71.

[0044] One or more second placement slots 72 for placing vacuum cleaner accessories are provided on the bracket 70. The second placement slots 72 can be used to place various accessories, and the accessories can be various suction heads, such as a flat suction head 83 and a brush suction head 82. The second placement slots 72 can also be set in various shapes that match the vacuum cleaner accessories.

[0045] The charging base is provided with a charging interface 65, and the charging interface 65 is externally connected to a charging plug, and the charging plug is plugged into a power source to charge the vacuum cleaner body 80. Of course, a plug can also be provided on the charging base for direct charging.

[0046] In the present invention, the steps are as follows:

[0047] 1. Press the button 62, and the bracket 70 pops up relative to the base 60;

[0048] 2. Take out the vacuum cleaner body 80, install the suction head on the vacuum cleaner body 80, stretch the dust cup to make the dust cup longer, so that the volume inside the dust cup becomes larger, and then perform the vacuuming operation;

[0049] 3. After vacuuming, pour out the dust in the dust cup and then shrink the dust cup;

[0050] 4. Place the vacuum cleaner body 80 in the first placement slot 71 and the suction head in the second placement slot 72;

[0051] 5. Press the bracket 70 downward until it fits the base 60 , and the hook 63 locks the bracket 70 on the base 60 ;

[0052] 6. The charging interface 65 is connected to a charger to charge the vacuum cleaner body 90 .

[0053] In the present invention, the dust cup can be retracted for easy storage, and the charging stand can be used as a storage box to store both the vacuum cleaner body and the accessories of the vacuum cleaner. When the vacuum cleaner body is in the storage state, the charging stand can charge the vacuum cleaner body.
