Description

Technical Field

[0001] The utility model relates to a vacuum cleaner and a dust cup assembly thereof. Background Art

[0002] A vacuum cleaner is a household appliance primarily used to clean dust, hair, debris, and other debris from floors. Its electric motor drives the impeller, generating a powerful airflow that draws in dust and dirt. A filter system then separates airborne particulate matter from the air, keeping the room clean. Modern vacuum cleaners are not limited to cleaning floors; they come in a variety of styles, including handheld, upright, and robotic models, suitable for cleaning in various applications.

[0003] The dust cup of a vacuum cleaner is a component that is used to collect sucked-in dust and garbage. Unlike traditional bag-type vacuum cleaners, vacuum cleaners with a dust cup design are more environmentally friendly because the dust cup is usually reusable and only needs to be cleaned regularly. In order to facilitate the cleaning of dust in the dust cup, current vacuum cleaner designs usually equip the dust cup with an openable lid and a button on the dust cup, which is opened by pressing the button. However, this setting requires the button to face outward, and a shielding structure cannot be set at the button, otherwise the button cannot be pressed, which makes it easy for the button to be accidentally touched. For example, if the vacuum cleaner accidentally falls or contacts a raised object or is misoperated, the dust cup lid will open and the debris in the dust cup will fall out, affecting the user experience. Utility Model Content

[0004] The purpose of the present utility model is to provide a vacuum cleaner and a dust cup assembly thereof to solve the technical problems mentioned in the above background technology.

[0005] The technical solution to achieve the purpose of the utility model is: a dust cup assembly of a vacuum cleaner, including a cup body, a cup cover, a locking structure and an unlocking structure, the cup body is cylindrical with one end open, one end of the cup cover is hinged to the cup body, and the other end is locked to the cup body through a locking structure, and the opening of the cup body is closed when the cup cover is closed; the unlocking structure is arranged on the outer wall of the cup body, and when the unlocking structure is pushed along the tangential direction or circumferential direction of the cup body, the unlocking structure pushes the locking structure to unlock, and the cup cover opens.

[0006] Furthermore, the locking structure includes a first locking portion arranged on the cup cover and a second locking portion arranged on the cup body, and the first locking portion and the second locking portion are clamped together; when the cup cover is in a closed state, the unlocking structure is pushed, and the unlocking structure pushes the first locking portion to disengage the first locking portion from the second locking portion.

[0007] Furthermore, a groove along the tangential direction or the circumferential direction is provided on the outer wall of the cup body, and the unlocking structure includes a push plate matching the shape of the groove, and an unlocking groove is provided on the push plate. When the cup cover is closed, the first locking part is located in the unlocking groove, and when the push plate is pushed, the first locking part disengages from the unlocking groove.

[0008] Furthermore, at least one side wall of the unlocking groove is an unlocking inclined surface. When the push plate is pushed, the first locking portion abuts against the unlocking inclined surface, and the first locking portion slides from bottom to top on the unlocking inclined surface.

[0009] Furthermore, the unlocking structure also includes an elastic member, a baffle parallel to the bottom surface of the groove is provided in the groove, two ends of the elastic member are respectively in contact with the baffle and the push plate, and when the push plate is pushed, the elastic member is compressed.

[0032] (Example 1)

[0033] See Figure 1 The vacuum cleaner of this embodiment includes a dust collection duct 4 and a dust cup assembly. The dust cup assembly includes a cup body 1, a cup cover 2, a locking structure and an unlocking structure 3. The cup body 1 is cylindrical with one end open. The cup cover 2 is hinged to the cup body 1 at one end and locked to the cup body 1 at the other end through a locking structure. When the cup cover 2 is closed, the opening of the cup body 1 is closed. The dust collection duct 4 is arranged on one side of the cup body 1 and fits the cup body 1. The unlocking structure 3 is arranged on the outer wall of the cup body 1 and is located between the dust collection duct 4 and the cup body 1. When the unlocking structure 3 is pushed along the tangential direction or circumferential direction of the cup body 1, the unlocking structure 3 pushes the locking structure to unlock, and the cup cover opens. This embodiment uses the dust collection duct 4 to shield the unlocking structure 3 to prevent the unlocking structure 3 from being accidentally touched or misoperated, which may cause the cup cover 2 to open and drop dirt.

[0034] Specifically, the locking structure includes a first locking portion 2-1 provided on the cup lid 2 and a second locking portion 1-1 provided on the cup body 1. The first locking portion 2-1 and the second locking portion 1-1 are engaged with each other; the engaging position of the first locking portion 2-1 and the second locking portion 1-1 is located between the dust collection duct 4 and the cup body 1. When the cup lid 2 is in the closed state, the unlocking structure 3 is pushed, and the unlocking structure 3 pushes the first locking portion 2-1 to disengage the first locking portion 2-1 from the second locking portion 1-1, thereby opening the cup lid 2.

[0035] The outer wall of the cup body 1 is provided with a groove 1-2 extending along a tangential or circumferential direction. In this embodiment, the bottom of the groove 1-2 is provided along a tangential direction of the cup body 1, and the position of the groove 1-2 corresponds to the dust collection duct 4. An unlocking structure 3 is provided within the groove 1-2. The unlocking structure 3 includes a push plate 3-1 whose shape matches the groove 1-2. The push plate 3-1 is provided with an unlocking groove 3-2, which cooperates with the first locking portion 2-1. When the cup lid 2 is closed, the first locking portion 2-1 is located in the unlocking groove 3-2; when the push plate 3-1 is pushed, the first locking portion 2-1 is disengaged from the unlocking groove 3-2.

[0036] At least one sidewall of the unlocking slot 3-2 is formed as an unlocking slope 3-2-1. When the push plate 3-1 is pushed, the first locking portion 2-1 abuts against the unlocking slope 3-2-1 and slides upward on the unlocking slope 3-2-1. The unlocking slope 3-2-1 pushes the first locking portion 2-1, disengaging it from the second locking portion 1-1, thereby opening the cup lid 2 and making it more convenient to use.

[0037] Unlocking mechanism 3 also includes an elastic member 3-3. A baffle 1-3 is positioned within recess 1-2, parallel to the bottom surface of recess 1-2. The ends of elastic member 3-3 abut against baffle 1-3 and push plate 3-1, respectively. When push plate 3-1 is pushed, elastic member 3-3 is compressed. Each time lid 2 is opened, elastic member 3-3 resets, automatically returning push plate 3-1 to its original position. In this embodiment, elastic member 3-3 is a compression spring.

[0038] The push plate 3-1 is at least partially disposed in the space between the baffle 1-3 and the bottom surface of the groove 1-2. Both sides of the cup body 1 can prevent the push plate 3-1 from falling.

[0039] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
