Description

Technical Field

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

[0002] With the increasing popularity of private cars in my country, car accessories are also booming. During car use, fine particles such as dust and snack crumbs can pollute the car's interior. Therefore, some car owners equip their vehicles with car vacuum cleaners. For example, Chinese Patent Application No. 202420734013.0 discloses a multi-functional car vacuum cleaner, which includes a mounting box, a handle fixedly connected to the lower end of the mounting box, a motor, a sieve cylinder, and a rotating ring installed inside the mounting box. The sieve cylinder is installed inside a collection box, and a mounting groove is provided inside the right end of the sieve cylinder. A connecting block is connected to the inner side of the mounting groove. A cleaning plate is installed through the inside of the sieve cylinder. The rotating ring is connected to a groove on the left end of the mounting box, and a push block is fixedly installed on the upper end of the rotating ring. This structure is common in current car vacuum cleaners. The collection chamber contains a filter to separate dust from the air and retain small particles. In most car vacuum cleaners, the main unit is connected to the dust collection chamber via clips, which press the filter firmly into the chamber. When not in use, the vacuum cleaner needs to be disassembled into multiple parts. After disassembly, the filter slips due to the loss of pressure from the main unit, causing dust to fall out of the dust collection chamber. Therefore, the existing dust collection chamber loses its storage capacity after disassembly, requiring owners to clean it before storage, which is inconvenient. Therefore, a new design is needed for the car vacuum cleaner's dust collection chamber where the filter is secured by a retaining ring. Even after the dust collection chamber is separated from the main unit, it prevents dust from escaping, reducing the cleaning cycle and making it more convenient for car owners. Utility Model Content

[0003] To address the aforementioned issues, this invention proposes a dust collection chamber for a car vacuum cleaner. The filter element is fixed within the dust collection chamber via a retaining ring. Even after the dust collection chamber is separated from the main unit, it ensures that dust within the chamber will not escape, reducing the cleaning cycle of the dust collection chamber and making it more convenient for car owners to use.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model proposes a dust collection chamber for a car vacuum cleaner, comprising: a cylinder, a filter element, a fixing ring, and an extension tube. A limiting ring is provided inside the cylinder, with one side of the filter element tightly attached to the limiting ring. An internal thread is provided on one side of the limiting ring on the inner wall of the cylinder. The fixing ring is installed inside the cylinder via the internal thread, with one side of the fixing ring tightly pressing against the other side of the filter element. One side of the cylinder is connected to the vacuum cleaner's main unit via a slot, and the other side of the cylinder is provided with a sleeve. One end of the extension tube is inserted into one end of the sleeve, and the other end of the sleeve is provided with a cover plate. The cover plate covers the opening of the sleeve and is hinged to the sleeve.

[0006] Furthermore, one end of the sleeve inside the cylinder curves upward, and the upper part of the cover plate is hinged to the curved end of the sleeve.

[0007] Furthermore, the sleeve is provided with a limiting block, and when the cover plate is flipped, one side of the cover plate rests against the limiting block.

[0008] Furthermore, a magnet is embedded in the lower part of the cover plate, and an iron sheet is embedded in the upper end of the sleeve at the corresponding position.

[0009] Furthermore, the fixing ring has Y-shaped or cross-shaped ribs in the middle.

[0010] Furthermore, the filter element has a groove on its outer periphery, and the limiting ring has a folded edge, with the groove of the filter element mounted on the folded edge of the limiting ring.

[0011] The beneficial effects of this utility model are as follows: by using a fixing ring and a limiting ring to fix the filter element to the cylinder, and by setting a cover plate on the sleeve to seal the sleeve, the filter element is still fixed in the cylinder after the cylinder is separated from the vacuum cleaner main unit, which prevents the garbage and dust in the cylinder from scattering. Car owners do not need to clean the cylinder every time they remove it, reducing the cleaning cycle of the cylinder and making it more convenient for car owners to use. Attached Figure Description

If the specific posture changes, the directional indicators will also change accordingly.

[0022] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" and "second" may explicitly or implicitly include at least one of the stated features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0023] like Figures 1 to 7 As shown, an embodiment of this utility model provides a dust collection chamber for a car vacuum cleaner, including: a cylinder 1, a filter element 2, a fixing ring 3, and an extension tube 5. A limiting ring 6 is provided inside the cylinder 1, and one side of the filter element 2 is tightly attached to the limiting ring 6. An internal thread is provided on the inner wall of the cylinder 1 on one side of the limiting ring 6. The fixing ring 3 is installed inside the cylinder 1 through the internal thread, and one side of the fixing ring 3 is tightly pressed against the other side of the filter element 2. One side of the cylinder 1 is connected to the vacuum cleaner main unit through a slot, and a sleeve 4 is provided on the other side of the cylinder 1. One end of the extension tube 5 is inserted into one end of the sleeve 4, and a cover plate 7 is provided at the other end of the sleeve 4. The cover plate 7 covers the opening of the sleeve 4, and the cover plate 7 is hinged to the sleeve 4.

[0024] A complete car vacuum cleaner consists of several parts, including the main vacuum cleaner unit, dust collection chamber, and brush head. This application mainly improves the dust collection chamber. A limiting ring 6 is provided inside the cylinder 1. After the filter element 2 is placed into the cylinder 1, the groove on the filter element 2 can be engaged with the folded edge on the limiting ring 6, making the axis of the filter element 2 coincide with the axis of the cylinder 1. Then, a fixing ring 3 is screwed into the cylinder 1. While the fixing ring 3 is fixed inside the cylinder 1 by its internal thread, the fixing ring 3 and the limiting ring 6 clamp the filter element 2. When the cylinder 1 is separated from the main vacuum cleaner unit, the filter element 2 is already fixed, preventing debris collected inside the cylinder 1 from accumulating. Dust and debris fall out from one side of the cylinder 1, while a sleeve 4 is located on the other side of the cylinder 1. The sleeve 4 connects to the extension tube 5, allowing dirt to be sucked out of confined spaces during vacuuming. The cover on the sleeve 4 is naturally closed, and the magnet 9 and the iron sheet attract each other, keeping the cover 7 closed even when tilted. Therefore, after the cylinder 1 is separated from the vacuum cleaner main unit and the extension tube 5, the debris and dust inside the cylinder 1 are less likely to fall out, reducing the cleaning cycle and making it more convenient for car owners. When cleaning the cylinder 1 is needed, simply unscrew the retaining ring 3, then remove the filter element 2 to empty the debris and dust from the cylinder 1.

[0025] In a preferred embodiment, such as Figure 2 , Figure 3 As shown, one end of the sleeve 4 inside the cylinder 1 is curved upwards, and the upper part of the cover plate 7 is hinged to the curved end of the sleeve 4. The sleeve 4 is mainly sealed by the cover plate 7. After the sleeve 4 is curved upwards, the cover plate 7 seals the sleeve 4 by gravity. During dust collection, the airflow pushes the cover plate 7 open, so that garbage and dust can be sucked into the cylinder 1.

[0026] Specifically, such as Figure 2 , Figure 3 As shown, the sleeve 4 is provided with a limiting block 8. When the cover plate 7 is flipped, one side of the cover plate 7 is pressed against the limiting block 8. When the opening angle of the cover plate 7 is too large, the cover plate 7 cannot seal the sleeve 4 by gravity after the dust is stopped. Therefore, the limiting block 8 is used to press against one side of the cover plate 7 to prevent the opening angle of the cover plate 7 from being too large.

[0027] In a preferred embodiment, such as Figure 2 , Figure 3 As shown, a magnet 9 is embedded in the lower part of the cover plate 7, and an iron piece is embedded in the corresponding position at the upturned end of the sleeve 4. When the cylinder 1 is removed from the vacuum cleaner main unit, it may be placed at an angle, which may cause the cover plate 7 to be opened accidentally. Therefore, a magnet 9 is embedded in the cover plate 7. Through the mutual attraction between the magnet 9 and the iron piece, the cover plate 7 is not easy to be opened. The magnetic force of the magnet 9 is small, and it can be blown open by the airflow during vacuuming to ensure normal vacuuming operation.

[0028] In a specific embodiment, such as Figure 6 As shown, the fixing ring 3 has a Y-shaped or cross-shaped rib 10 in the middle. The fixing ring 3 is hollow in the middle to facilitate the airflow through the filter core 2 and then through the fixing ring 3. In addition to enhancing the structural strength of the fixing ring 3, the rib 10 can also provide a gripping position, making it convenient for the user to rotate the fixing ring 3.

[0029] In one specific embodiment, the filter element 2 has a groove on its outer periphery and a folded edge on the limiting ring 6. The groove of the filter element 2 is installed on the folded edge of the limiting ring 6, so that the filter element 2 can be installed coaxially with the cylinder 1 when it is installed. At the same time, the groove and the folded edge can increase the airtightness between the filter element 2 and the limiting ring 6 and avoid air leakage.

[0030] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
