Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and in particular to a dust collection device for a vacuum cleaner. Background Technology

[0002] Vacuum cleaners utilize an electric motor to drive blades to rotate at high speed, creating negative air pressure within a sealed casing to suck up dust and debris. Vacuum cleaners are mainly divided into three types: household vacuum cleaners, commercial vacuum cleaners, and industrial vacuum cleaners. Among them, cyclone dust collectors are a type of dust removal device. Their dust removal mechanism involves causing the dust-laden airflow to rotate, using centrifugal force to separate dust particles from the airflow and collect them on the inner wall of the device. Gravity then causes the dust particles to fall into the dust hopper, while the purified gas is discharged through the exhaust port.

[0003] Existing vacuum cleaners typically use their dustbins or ash hoppers as a single unit. For example, the portable vacuum cleaner disclosed in patent application number 201620102901.6 has a dust collection box comprising a housing and a dust filter. The dust filter is positioned on the side of the housing opposite the suction device, forming a dust collection chamber between the side wall of the dust filter and the housing. This type of dust collection chamber is inconvenient to disassemble and clean due to limitations imposed by the suction hose. Furthermore, existing dustbins or ash hoppers can generally only be attached to a fixed position on the vacuum cleaner, resulting in limited usage options, poor flexibility, and a restricted range of applications.

[0028] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0029] Example 1:

[0030] This embodiment provides a dust collection device for a vacuum cleaner, such as... Figures 1-7 As shown, it includes a first dust collection unit 1 and a second dust collection unit 2. The first dust collection unit 1 has a cylindrical structure, and the second dust collection unit 2 has a conical structure. The cylindrical first dust collection unit 1 not only increases the storage capacity of waste but also prevents damage caused by excessive internal pressure. The conical second dust collection unit 2 uses its inclination to increase the discharge speed of internal waste, making it less likely for waste to accumulate inside the dust collection unit.

[0031] The large-diameter ends of the first dust collection section 1 and the second dust collection section 2 are detachably connected. A first connection port 12 and a second connection port 22 are respectively provided at opposite ends of the first dust collection section 1 and the second dust collection section 2. One of the first connection port 12 and the second connection port 22 is connected to the separation device of the vacuum cleaner, and the other connection port is used as an exhaust port or is closed.

[0032] The dust collection device in this embodiment features a first dust collection section 1 and a second dust collection section 2, which are detachably connected. When the dust collection device is removed from the vacuum cleaner for cleaning, it can be disassembled into the first dust collection section 1 and the second dust collection section 2 for separate cleaning, facilitating internal cleaning and resulting in better cleaning. Furthermore, both the first connection port 12 and the second connection port 22 in this embodiment can be connected to the vacuum cleaner's detachment device, thereby increasing installation options and improving usage flexibility.

[0033] In a preferred embodiment, a buckle 51 and a locking block 52 are respectively provided on the first dust collection unit 1 near the adjacent end of the second dust collection unit 2, and the buckle 51 and the locking block 52 are engaged with each other. When the buckle 51 is installed on the first dust collection unit 1, the corresponding locking block 52 is connected to the second dust collection unit 2. When the buckle 51 is installed on the second dust collection unit 2, the locking block 52 is connected to the first dust collection unit 1. Two sets of buckles 51 and locking blocks 52 are provided, and the two sets of buckles 51 and locking blocks 52 are arranged opposite each other on both sides of the first dust collection unit 1 and the second dust collection unit 2 to make the connection between the two sides of the first dust collection unit 1 and the second dust collection unit 2 more secure.

[0034] As a preferred embodiment, such as Figure 4 As shown, a snap-fit ​​edge 23 extending outward is provided on the second dust collection section 2 near the end of the first dust collection section 1. A snap-fit ​​groove 24 is provided on the snap-fit ​​edge 23, facing the opening of the first dust collection section 1, and snaps into the side of the first dust collection section 1. A snap-fit ​​block 52 is connected to the snap-fit ​​edge 23, and a snap-fit ​​buckle 51 on the first dust collection section 1 snaps into the snap-fit ​​block 52. The snap-fit ​​buckle 51 has a snap-fit ​​hole that matches the snap-fit ​​block 52.

[0035] In this embodiment, by engaging the second dust collection part 2 with the first dust collection part 1 through the snap-fit ​​groove 24, the sealing of the connection between the second dust collection part 2 and the first dust collection part 1 is improved, thus preventing air leakage.

[0036] In a preferred embodiment, a plurality of first reinforcing ribs 11 are provided on the outer peripheral cylindrical wall of the first dust collection part 1, and the first reinforcing ribs 11 are arranged along the axial direction of the first dust collection part 1. The first reinforcing ribs 11 provide support and reinforcement to the side wall of the first dust collection part 1, thereby improving the stability of the first dust collection part 1.

[0037] Multiple second reinforcing ribs 21 are provided on the outer peripheral sidewall of the second dust collection section 2. The second reinforcing ribs 21 are arc-shaped and extend from one end near the first dust collection section 1 to the second connection port 22. The second reinforcing ribs 21 provide support and reinforcement to the sidewall of the second dust collection section 2, making the second dust collection section 2 more stable.

[0038] In this embodiment, both the second dust collection unit 2 and the first dust collection unit 1 have good support strength, good stability, and long service life. The first dust collection unit 1 and the second dust collection unit 2 can be made of plastic or metal.

[0039] In a preferred embodiment, a plurality of connection positions are provided on the first dust collection part 1 near the first connection port 12, and the plurality of connection positions are evenly distributed along the edge of the first dust collection part 1. A roller 7 is detachably installed on the connection position, and the second connection port 22 is connected to the separation device of the vacuum cleaner. The second connection port 22 can be connected to the cyclone separation device of the vacuum cleaner via a flange.

[0040] In this embodiment, the cyclone separator draws dust particles into the dust collection device through the second connection port 22, thereby collecting the dust particles.

[0041] Specifically, a connecting groove 13 can be provided at the connecting position, and a mounting block is provided on the support leg 71. The support leg 71 is mounted on the connecting groove 13 via the mounting block, and the roller 7 is mounted on the support leg 71. The roller 7 can be a swivel wheel with brake pads to facilitate multi-directional movement. Alternatively, the support leg 71 can also be directly mounted to the connecting position using screws.

[0042] In a preferred embodiment, a removable cover plate 8 is provided at the first connection port 12, which can seal the first connection port 12. When the second connection port 22 is connected to the separation device of the vacuum cleaner, the first connection port 12 can be closed by the cover plate 8, so that dust particles can remain in the first dust collection part 1.

[0043] When using the dust collection device in this embodiment, such as Figure 6 and Figure 7 As shown, the first dust collection unit 1 is installed on the bottom side of the second dust collection unit 2. The first connection port 12 on the first dust collection unit 1 is sealed by the cover plate 8, and the second connection port 22 on the second dust collection unit 2 is connected to the cyclone separator of the vacuum cleaner. By installing a support leg 71 and a roller 7 on the end of the first dust collection unit 1 near the first connection port 12, the dust collection device can be moved during use, thus realizing a dust removal method while moving. The dust particles separated by the cyclone separator enter the interior of the dust collection device through the second connection port 22 and then fall into the first dust collection unit 1. When the dust removal is finished or the dust particles in the dust collection device accumulate to a certain height, the first dust collection unit 1 and the second dust collection unit 2 can be separated by opening the buckle 51 and the locking block 52, and the dust particles in the first dust collection unit 1 can be poured out.

[0044] In a preferred embodiment, a hanging assembly 4 is provided on the side wall of the first dust collection unit 1, and the unit is hung on the wall via the hanging assembly 4. The first dust collection unit 1 can be installed on the wall via the hanging assembly 4, thereby facilitating the fixing of the dust collection device and not occupying floor space.

[0045] In one preferred embodiment, the mounting assembly includes a first mounting plate 41 and a second mounting plate 42. The first mounting plate 41 is provided with two oppositely arranged slots 411, and the second mounting plate 42 is provided with two hooks 421 that are adapted to the slots 411. The second mounting plate 42 is connected to the first mounting plate 41 by the hooks 421 being engaged in the slots 411.

[0046] like Figure 2 and Figure 3 As shown, the first mounting plate 41 is connected to the mounting part 43 on the side wall of the first dust collection unit 1 by screws, and the second mounting plate 42 is fixedly connected to the wall. The dust collection device can be installed on the wall by sliding the hook 421 from the top into the slot 411, so that the hook 421 and the slot 411 are engaged. This makes it convenient to remove or install the dust collection device from the wall and provides high flexibility in use.

[0047] As a preferred embodiment, such as Figure 1 and Figure 4 As shown, a discharge bend 3 is detachably connected at the second connection port 22. A baffle 31 is provided at the outlet end of the discharge bend 3, and the upper end of the baffle 31 is hinged to the discharge bend 3. The baffle 31 can block the outlet end of the discharge bend 3, thereby sealing the inside of the dust collection device and preventing internal dust particles from falling out. The baffle 31 can be a circular plate structure.

[0048] In its natural state, the cover 31 has a gap between itself and the outlet end of the unloading bend 3, allowing dust particles inside the dust collection device to fall out. When the dust collection device is under negative pressure, the cover 31 will seal the outlet end of the unloading bend 3 to prevent dust particles inside the dust collection device from falling out.

[0049] In a preferred embodiment, the curvature of the discharge bend 3 is α, where 60 ≤ α < 90°. The curvature of the discharge bend 3 allows for a gap between the baffle 31 and the outlet end of the discharge bend 3 when the dust collection device is in an upright state, so that all dust particles inside the dust collection device can flow out in a timely manner under natural conditions.

[0050] Specifically, a limiting block 32 is provided on the lower side of the discharge bend 3. The limiting block 32 can limit the cover 31 when it is placed on the outlet end of the discharge bend 3. A connecting seat 33 is provided on the lower side of the discharge bend 3, and the limiting block 32 is rotatably connected to the connecting seat 33. When the cover 31 is placed on the outlet end of the discharge bend 3, the limiting block 32 can rotate to lock onto the cover 31. The limiting block 32 facilitates the manual closing of the outlet end of the discharge bend 3 with the cover 31.

[0051] When using the dust collection device in this embodiment, such as Figure 1 As shown, the first dust collection unit 1 is installed on the top side of the second dust collection unit 2. The first connection port 12 on the first dust collection unit 1 is connected to the cyclone separator of the vacuum cleaner, and the second connection port 22 on the second dust collection unit 2 is connected to the discharge elbow 3. By providing a hanging assembly on the first dust collection unit 1, the dust collection device can be easily hung on the wall for use, avoiding the occupation of floor space. The dust particles separated by the cyclone separator enter the interior of the dust collection device through the first connection port 12, and then fall into the second dust collection unit 2 and accumulate. When the dust collector is turned on, the negative pressure inside the dust collection device causes the cover 31 to cover the outlet end of the unloading bend 3, preventing dust particles inside the second dust collection section 2 from falling. When the dust collector is turned off, the negative pressure inside the dust collection device disappears, and the cover 31 opens the outlet end of the unloading bend 3, allowing the dust particles inside the dust collection device to fall. A collection bucket can be placed below the outlet end of the unloading bend 3 to catch the dust particles falling from the dust collection device, so that the dust particles can automatically fall into the collection bucket after the dust collector is turned off, making dust removal more convenient.

[0052] The dust collection device in this embodiment can be used on the ground or hung on the wall, offering diverse usage options and high flexibility.

[0053] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any modifications and improvements made by those skilled in the art without departing from the inventive concept of the present utility model should be covered within the protection scope of the present utility model.
