[0023] This application relates to a portable vacuum cleaner. The portable vacuum cleaner includes: a main body with a handle, a battery pack mounted on the main body, a suction motor electrically connected to the battery pack, and a dust cup device fluidly connected to the suction motor. In most portable vacuum cleaners, the dust cup device is detachably mounted to the main body. The dust cup device includes: a dust cup housing defining a dust collection chamber on its inner side, a mesh filter extending into the dust cup housing, and a dust cup bottom cover located at the lower part of the dust cup housing and capable of selectively opening and closing the dust collection chamber. The dust cup bottom cover is configured to switch from a closed position to an open position in response to the actuation of a release member.

[0024] Figure 1 This is an illustrative example of a portable vacuum cleaner 100. The portable vacuum cleaner 100 includes: a main body 1 having a handle 11; a battery pack 2, mounted on the main body 1 and located at one end of the handle 11; an air inlet pipe 3, integrally formed on the main body 1 and having an air inlet 31 at its front; a suction motor 4, mounted on the main body 1 and located at the other end of the handle 11; and a dust collection cup 5, detachably connected to the main body 1 and fluidly connected to the suction motor 4. The suction motor 4 is configured to cause a flow of dust-laden air from the air inlet 31 and along the air inlet pipe 3 into the dust collection cup 5.

[0025] See Figure 2 The dust cup device 5 includes a dust cup housing 51, a mesh filter 52, and a dust cup bottom cover 53. The dust cup housing 51 is cylindrical and includes a peripheral sidewall 511 and a bottom wall 512 extending radially inward from a portion of the inner wall of the peripheral sidewall 511. A dust collection chamber 510 is formed inside the dust cup housing 511. The dust collection chamber 510 has a rotation axis Z extending longitudinally. The rotation axis Z passes through the bottom wall 512. The dust cup housing 51 is typically a one-piece injection molded component. An inlet 5111 is provided on the peripheral sidewall 511 of the dust cup housing 51, which connects to the air inlet pipe 3. The inlet 5111 is configured to allow the dust-laden airflow to enter the dust collection chamber 520 in a spiral manner. The mesh filter 52 is located at the center of the dust collection chamber 510. Large particles of debris can be intercepted by the mesh filter 52 and retained in the dust collection chamber 510, while only fine dust particles can escape to the outside of the dust collection cup device 5 with the air.

[0026] The dust cup bottom cover 53 is attached to the lower part of the dust cup housing 51 and is configured to be rotatably disposed between an open position (open dust collection chamber 510) and a closed position (closed dust collection chamber 510). When the dust cup bottom cover 53 is in the open position, dust in the dust collection chamber 510 can be discharged from the cup.

[0027] like Figure 4 As shown, the dust cup bottom cover 53 has a notch 54. The shape of the notch 54 is adapted to the shape of the bottom wall 512. In this example, the bottom wall 512 is fan-shaped. The center point of the dust cup bottom cover 53 is located at the notch 54. When the dust cup bottom cover 53 is in the closed position, the bottom wall 512 is located at the notch 54 and a sealing engagement is formed between the two.

[0028] Continue as Figure 2 As shown, the bottom wall 512 has a ramp structure that extends from the inner wall surface of the peripheral side wall 511 toward the inner and lower direction; this ramp structure can prevent dust from staying on the bottom wall 512, thereby making it easier for dust in the dust collection chamber 510 to be discharged.

[0029] The dust cup bottom cover 53 extends along a plane P. When the dust cup bottom cover 53 is in the closed position, the bottom wall 512 is recessed inward relative to the plane P to form a cavity 513. The cavity 513 can provide storage space for small parts.

[0030] like Figure 2 , Figure 3 As shown, the dust collection cup device 5 also includes a cleaning brush tool 55. The cleaning brush tool 55 is detachably housed in the cavity 513. This cleaning brush tool 55 can be used to wipe away adhering dirt from surfaces such as the mesh filter 52.

[0031] In some embodiments, a light can also be installed on the bottom wall of the dust cup housing 53. This light can help the user observe the dust on the target surface, especially the surface areas where there are nooks and crannies.

[0032] like Figure 5 , Figure 6As shown, the dust cup bottom cover 53 has a first end 531 and a second end 532 that are radially spaced apart from each other. The first end 531 is rotatably connected to the bottom wall 512 via a pair of pivots 533. The pair of pivots 533 define a transverse axis X. A pair of torsion springs 534 are also provided between the first end 531 and the bottom wall 512. When the dust cup bottom cover 53 is rotated from the closed position to the open position, the dust cup bottom cover 53 rotates about the transverse axis X. The pair of torsion springs 534 are used to bias the dust cup bottom cover 53 toward the closed position. A pair of gears 535 are also fixedly provided on the pair of pivots 533, and a pair of racks 536 mesh with the pair of gears 535. The pair of racks 536 are movably disposed on the dust cup housing 511 in the vertical direction; for example, when the pair of racks 536 move upward, the pair of racks 536 rotate, thereby causing the dust cup bottom cover 53 to rotate about the transverse axis X. Therefore, by causing a pair of racks 536 to move upward relative to the dust cup housing 511, the dust cup bottom cover 53 can be switched from the closed position to the open position.

[0033] A locking assembly 57 is provided on the dust cup housing 511. The locking assembly 57 is operably connected to the second end 532 of the dust cup bottom cover 53 and configured to secure the dust cup bottom cover 53 in a closed position. The locking assembly 57 includes a sliding member 571 that can slide up and down relative to the dust cup housing 511, a spring 572 disposed between the sliding member 571 and the dust cup housing 511, and a magnetic member 573. A magnetic attraction member 58 is provided at the second end 532 of the dust cup bottom cover 53.

[0034] like Figure 1 As shown, the outer wall of the dust cup housing 511 is provided with a vertically extending groove 514, and the sliding component 571 can slide up and down along the groove 514. The sliding component 571 is provided with a laterally protruding pressing part 5711. The magnetic component 573 is fixed to the lower part of the sliding component 571.

[0035] like Figure 2 As shown, when the magnetic component 58 and the magnetic component 573 are attracted together, the dust cup bottom cover 53 will be fixed in the closed position. When the pressing part 5711 is operated, the magnetic component 58 can be separated from the magnetic component 573.

[0036] The dust collection cup device of this application, by providing a notch on the bottom cover and a bottom wall for the dust cup housing, allows designers to install or store vacuum cleaner components at the bottom wall, thereby expanding the design space of the vacuum cleaner.

[0037] The above embodiments are merely illustrative examples, and those skilled in the art can make equivalent substitutions or improvements within the scope of the claims. Other embodiments, besides the exemplary embodiments shown and described herein, are also covered within the scope of this invention.
