Description

Technical Field

[0001] This application relates to the field of cleaning device technology, and in particular to a dust collection box assembly and a dust collection device. Background Technology

[0002] The dust from the vacuum cleaner is collected in a dustbin located at the bottom or side of the machine. After vacuuming, you need to use a cleaning brush or other cleaning tools to clean the dustbin for the next use.

[0003] In related technologies, cleaning tools such as cleaning brushes are usually separate from vacuum cleaners and need to be stored in storage bags or boxes, which is inconvenient to store and easy to lose. Moreover, when users want to clean the dustbin, they usually need to specifically look for or retrieve the cleaning brush, making the use of the cleaning brush inconvenient. Utility Model Content

[0004] This application provides a dust collection box assembly and a vacuuming device that provides convenience for storing and using cleaning tools such as cleaning brushes.

[0005] The technical solution is as follows: On one hand, this application provides a dust collection box assembly, which includes: a dust cup, a dust filter, and a cleaning component; the dust filter is installed inside the dust cup, and the cleaning component is detachably installed on the dust filter, wherein the dust filter and at least a portion of the cleaning component are arranged sequentially along the suction airflow direction of the vacuum cleaner.

[0006] In the dust collection box assembly provided in this application, the cleaning component is detachably mounted on the dust filter within the dust cup. When the cleaning component needs to be used to clean the dust in the dust cup, it can be detached from the dust filter for use. Therefore, the cleaning component is easy to store, not easily lost, and convenient to use. Furthermore, although the cleaning component is mounted on the dust filter, it is located after the dust filter along the airflow direction of the vacuum cleaner. This ensures that the dust-carrying airflow first passes through the dust filter to remove dust, and then the clean air passes through the cleaning component. This does not affect the dust filtering function of the dust filter, nor does it cause the cleaning component to become dirty.

[0007] In some possible implementations, the dust filter element is a cylindrical structure, and at least part of the cleaning element is located in the internal space of the dust filter element.

[0008] With the above arrangement, the cleaning component can be cleverly installed in the internal space of the dust filter component itself, without the need to design additional storage space and storage structure for the cleaning component, and without affecting the appearance of the dust collection box component.

[0009] In some possible implementations, the cleaning component includes a brush head, a brush handle, and a sealing block, with the brush head and the sealing block respectively connected to both ends of the brush handle; the brush handle and the brush head can be inserted into the internal space of the dust filter, and at least part of the sealing block is located outside the internal space of the dust filter.

[0010] With the above arrangement, the brush handle and brush head of the cleaning component can be inserted into the internal space of the dust filter component, thereby utilizing the internal space of the dust filter component itself to store the cleaning component without the need for additional storage space design, thus improving the space utilization rate inside the dust collection box assembly.

[0011] In some possible implementations, the sealing block can make sealing contact with one open end of the dust filter element, and at least a portion of the cross-sectional area of ​​the sealing block is greater than or equal to the end area of ​​the open end of the dust filter element.

[0012] With the above arrangement, the sealing block of the cleaning component can seal the opening end of the dust filter component, preventing dust-laden airflow from bypassing the filter screen and directly entering the internal space of the dust filter component, thus avoiding the failure of the dust filtering function of the dust filter component.

[0013] In some possible implementations, the sealing block is a stepped columnar structure, including a first column and a second column connected at their ends, wherein the cross-sectional area of ​​the first column is greater than the cross-sectional area of ​​the second column; the end face of the second column away from the first column is connected to the brush handle, the cross-sectional area of ​​the first column is greater than the end area of ​​the opening end of the dust filter, and the cross-sectional area of ​​the second column is equal to or less than the end area of ​​the opening end of the dust filter.

[0014] With the above arrangement, when the cleaning component is installed on the dust filter, the second column of the sealing block of the cleaning component extends into the internal space of the dust filter through the open end and makes sealing contact with the inner wall of the dust filter; the first column of the sealing block of the cleaning component overlaps with the end face of the open end, thus improving the sealing performance of the open end of the dust filter, blocking the path of dust-laden airflow directly into the internal space from the open end of the dust filter, and preventing the dust filtering function of the dust filter from failing.

[0015] In some possible implementations, the dust cup includes a cup body and a cup lid, with both the dust filter and the cleaning component housed within the cup body; wherein a sealing block of the cleaning component is disposed between the cup lid and the dust filter, and the sealing block is capable of sealingly contacting both the cup lid and the dust filter.

[0016] With the above arrangement, the sealing block of the cleaning component is tightly clamped between the cup lid of the dust cup and the dust filter, so there is no need to set an additional fixing structure for the cleaning component on the dust filter, and the sealing effect of the sealing block on the opening end of the dust filter is enhanced.

[0017] In some possible implementations, the cup lid is provided with an annular enclosure, the interior of which can accommodate the portion of the sealing block located outside the internal space of the dust filter.

[0018] With the above arrangement, the annular enclosure protects the part of the sealing block located outside the internal space of the dust filter, which can reduce the dirt caused by dust covering this part and keep the sealing block in a relatively clean state. This way, users will not get their hands dirty when cleaning the dust cup with the cleaning device.

[0019] In some possible implementations, the inner contour shape of the annular enclosure matches the outer contour shape of the sealing block.

[0020] With the above arrangement, the annular enclosure can completely cover the outside of the part of the sealing block located outside the internal space of the dust filter, preventing this part from being covered by dust and becoming dirty.

[0021] In some possible implementations, the dust filter element is a cyclone separator.

[0022] In this application, a cyclone separator is used to utilize centrifugal force to quickly settle large dust particles in the airflow, achieving efficient separation and significantly reducing the probability of filter clogging, thus maintaining consistent suction power. Furthermore, the cyclone separator itself has process holes, which can be directly used to house cleaning components without requiring additional openings, resulting in a simpler structure for the dust filter.

[0023] On the other hand, this application provides a vacuum cleaner device, which includes a device body, a fan, and the dust collection box assembly described in the previous aspect.

[0024] The vacuum cleaner of this application uses the dust collection box assembly of this application, and therefore has all the beneficial technical effects of all embodiments herein. Attached Figure Description

When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application.

[0030] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art.

[0031] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0032] This application provides a dust collection box assembly, such as... Figure 1As shown, the dust collection box assembly includes a dust cup 1, a filter element 2, and a cleaning element 3. The filter element 2 is installed inside the dust cup 1 and is used to filter the airflow carrying dust to separate the dust from the clean air. The cleaning element 3 is detachably installed on the filter element 2 and is used to clean the filter screen of the dust cup 1 and the filter element 2. The filter element 2 and at least a portion of the cleaning element 3 are arranged sequentially along the direction of the suction airflow of the vacuum cleaner.

[0033] In summary, the dust collection box assembly provided in this application has a cleaning component 3 that is detachably installed on the dust filter component 2 in the dust cup 1. For example, it can be detachably installed on the dust filter component 2 by means of snap-fit ​​or plug-in. When it is necessary to use the cleaning component 3 to clean the dust in the dust cup 1, the cleaning component 3 can be removed from the dust filter component 2 for use. Therefore, the cleaning component 3 is easy to store, not easy to lose, and easy to take and use.

[0034] Furthermore, although the cleaning component 3 is installed on the dust filter 2, it is positioned after the dust filter 2 along the direction of the suction airflow of the vacuum cleaner. In this way, after the dust-laden airflow is sucked into the dust cup 1, it will first pass through the dust filter 2 to separate the dust from the clean air. The dust is filtered out and remains in the dust cup 1, while the clean air flows to the cleaning component 3. Therefore, this arrangement will not affect the dust filtering function of the dust filter 2, nor will it cause the cleaning component 3 to become dirty.

[0035] In some possible implementations of the embodiments of this application, such as Figure 1 As shown, the dust filter 2 is a hollow cylindrical structure. When the cleaning component 3 is installed on the dust filter 2, at least part of the cleaning component 3 is located in the internal space of the dust filter 2.

[0036] With the above arrangement, the cleaning component 3 can be cleverly installed in the internal space of the dust filter component 2 itself. Therefore, there is no need to plan additional storage space and design storage structure for the cleaning component 3 in the dust cup 1, and it will not affect the appearance of the dust collection box assembly. This improves the compatibility of the dust collection box assembly with other parts of the vacuum cleaner (such as the device body).

[0037] In some possible implementations of the embodiments of this application, such as Figure 1 and Figure 2 As shown, filter element 2 is a cyclone separator. A cyclone separator is a dry dust removal device that uses centrifugal force to achieve gas-solid separation. It has high separation efficiency and is commonly found in handheld / upright vacuum cleaners. Figure 1 The directions shown are used as an example for illustration. See [link / reference]. Figure 1The lower cylinder of the cyclone separator is the main rotating chamber, cylindrical in shape, where the airflow can generate strong vortices. The upper cylinder is a gradually narrowing cone, with a smaller radius of rotation, allowing the airflow to generate vortices at greater speeds, further increasing centrifugal force. When dust-laden airflow passes through the cyclone separator, larger dust particles are trapped and settled by the separator's walls, while the purified air (possibly carrying some finer dust particles that were not separated) is discharged through the cyclone separator.

[0038] In this embodiment, a cyclone separator utilizes centrifugal force to rapidly settle large dust particles in the airflow, achieving efficient separation and significantly reducing the probability of filter clogging, thus maintaining consistent suction power. Furthermore, as... Figure 2 As shown, the top of the upper cylinder of the cyclone separator has a process hole, which can be directly used as the insertion port for the cleaning component 3 to store the cleaning component 3 without the need for additional openings, thus making the structure of the dust filter component 2 simpler.

[0039] In some possible implementations of the embodiments of this application, see also... Figure 1 The cleaning component 3 includes a brush head 31, a brush handle 32, and a sealing block 33. The brush head 31 and the sealing block 33 are respectively connected to the two ends of the brush handle 32. The brush handle 32 and the brush head 31 can be inserted into the internal space of the dust filter 2, and at least part of the sealing block 33 is located outside the internal space of the dust filter 2.

[0040] For example, the sealing block 33 can be a soft sealing element made of soft materials such as silicone or soft rubber, and its shape and size can be designed and adjusted according to actual needs.

[0041] With the above arrangement, the brush handle 32 and brush head 31 of the cleaning component 3 can be inserted into the internal space of the dust filter component 2, thereby utilizing the internal space of the dust filter component 2 itself to store the cleaning component 3 without the need for additional storage space design, thus improving the space utilization rate inside the dust collection box assembly.

[0042] In some possible implementations of the embodiments of this application, such as Figure 1 and Figure 2 As shown, one end of the dust filter 2 is open to form an open end 21. After the cleaning component 3 is installed on the dust filter 2, the brush handle 32 and the brush head 31 extend into the internal space of the dust filter 2 through the open end 21, and at least a portion of the sealing block 33 is located outside the dust filter 2 and is in sealing contact with the open end 21 of the dust filter 2.

[0043] Since the cross-sectional area of ​​at least part of the sealing block 33 is greater than or equal to the end area of ​​the opening end 21 of the dust filter 2, the sealing block 33 will seal the opening end 21 of the dust filter 2, so that the airflow cannot pass through the opening end 21, but can only flow through the filter screen of the dust filter 2, thereby preventing the dust-laden airflow from bypassing the filter screen of the dust filter 2 and directly entering the internal space of the dust filter 2, thus avoiding the failure of the dust filtering function of the dust filter 2.

[0044] In some possible implementations of the embodiments of this application, such as Figure 3 As shown, the sealing block 33 has a stepped columnar structure, including a first column 331 and a second column 332, wherein the cross-sectional area of ​​the first column 331 is larger than the cross-sectional area of ​​the second column 332. Along the axial direction of the brush handle 32, the end faces of the first column 331 and the second column 332 are connected. The end face of the second column 332 away from the first column 331 is connected to the brush handle 32. The cross-sectional area of ​​the first column 331 is larger than the end area of ​​the opening end 21 of the dust filter element 2, and the cross-sectional area of ​​the second column 332 is equal to or smaller than the end area of ​​the opening end 21 of the dust filter element 2. Furthermore, the cross-sectional area of ​​the second column 332 is greater than or equal to the cross-sectional area of ​​the brush handle 32.

[0045] With the above arrangement, when the cleaning component 3 is installed on the dust filter 2, the second column 332 of the sealing block 33 of the cleaning component 3 will extend into the internal space of the dust filter 2 through the opening end 21 and make sealing contact with the inner wall of the dust filter 2; the first column 331 of the sealing block 33 of the cleaning component 3 will seal and overlap the end face of the opening end 21, thus improving the sealing performance of the opening end 21 of the dust filter 2, blocking the path of dust-laden airflow from the opening end 21 of the dust filter 2 directly into the internal space, and preventing the dust filtering function of the dust filter 2 from failing.

[0046] In some possible implementations of the embodiments of this application, such as Figure 1 As shown, the dust cup 1 includes a cup body 11 and a cup lid 12, with the dust filter 2 and the cleaning component 3 both housed within the cup body 11. The sealing block 33 of the cleaning component 3 is disposed between the cup lid 12 and the dust filter 2, and the sealing block 33 can achieve a sealing contact with both the cup lid 12 and the dust filter 2.

[0047] With the above arrangement, when the cleaning component 3 is installed on the dust filter 2 and the cup lid 12 of the dust cup 1 is closed, the sealing block 33 of the cleaning component 3 is tightly clamped between the cup lid 12 of the dust cup 1 and the dust filter 2. Therefore, there is no need to set an additional fixing structure for the cleaning component 3 on the dust filter 2, which can achieve the fixation of the cleaning component 3 in the dust cup 1 and prevent the cleaning component 3 from moving during the vacuuming process. Moreover, this measure can further enhance the sealing effect of the sealing block 33 on the opening end 21 of the dust filter 2, ensuring that the airflow carrying dust cannot bypass the filter screen of the dust filter 2 and directly enter the internal space of the dust filter 2.

[0048] In some possible implementations of the embodiments of this application, such as Figure 1 As shown, the cup lid 12 is provided with an annular baffle 13, which is located on the surface of the cup lid 12 facing the inside of the cup body 11. After the cup lid 12 is closed on the cup body 11, the interior of the annular baffle 13 can accommodate the portion of the sealing block 33 located outside the internal space of the dust filter 2.

[0049] By adopting the above arrangement, the annular enclosure 13 can protect the portion of the sealing block 33 located outside the internal space of the dust filter 2, thereby reducing the dirt caused by dust covering this portion and keeping the sealing block 33 relatively clean. Since the sealing block 33 also serves as a handle, meaning that the user will generally hold the sealing block 33 when using the cleaning device 3, it ensures that the user's hands will not get dirty when cleaning the dust cup 1 using the cleaning device 3.

[0050] In some possible implementations of this application, the inner contour shape of the annular enclosure 13 matches the outer contour shape of the sealing block 33.

[0051] With the above arrangement, after the cup lid 12 is closed, the annular barrier 13 can completely cover the outer side of the portion of the sealing block 33 located outside the internal space of the dust filter 2, and the inner peripheral wall of the annular barrier 13 fits against the outer peripheral wall of the sealing block 33, thus avoiding dirt caused by dust covering the outer peripheral wall of the sealing block 33.

[0052] In summary, the dust collection box assembly provided in this application embodiment detachably mounts the cleaning component 3 (e.g., a cleaning brush) onto the dust filter component 2 within the dust cup 1. Compared to related technologies that use storage bags or boxes to separately store the cleaning brush, this facilitates the storage and retrieval of the cleaning component 3 and reduces the likelihood of it being lost. Furthermore, the dust cup 1 does not require additional storage space for the cleaning component 3, nor does it require additional storage structures on the dust filter component 2. It also does not affect the overall appearance of the dust collection box assembly, ensuring compatibility between the dust collection box assembly and the main body of the vacuum cleaner.

[0053] This application provides a vacuum cleaner, which includes a device body (not shown in the figure), a fan (not shown in the figure), and a dust collection box assembly as described in the above embodiments. Both the fan and the dust collection box assembly are mounted on the device body. The fan generates negative pressure airflow to draw in dust, and the dust collection box assembly captures and collects large dust particles from the dust-laden airflow.
