Description

Technical Field

[0001] This utility model belongs to the field of vacuum cleaner technology, and relates to a dust cup assembly structure and a handheld vacuum cleaner. Background Technology

[0002] In modern life, handheld vacuum cleaners have become a powerful tool for cleaning many households due to their convenience and efficiency. Handheld vacuum cleaners typically consist of main components such as the body, nozzle, and dust cup, with the dust cup playing a crucial role in collecting dust and debris.

[0003] After using a handheld vacuum cleaner for a period of time, users need to remove the dust cup to clean the dust inside. Currently, most handheld vacuum cleaners use a clip-on design to attach the dust cup to the body. This installation method is convenient initially, allowing for quick connection and fixation of the dust cup to the body.

[0004] However, problems gradually emerged as the vacuum cleaner was used for a longer period. Because the vacuum cleaner sucks in a large amount of dust and debris during operation, some dust inevitably gets into the latching area. This dust gradually accumulates in the gap between the latch and the slot, forming a dust accumulation layer. As the dust accumulation increases, the dust cup encounters significant resistance when rotating and disassembling, becoming quite difficult.

[0005] On the one hand, the accumulation of dust alters the original state of the latch, making the fit between the latch and the dust cup less tight and smooth. The latch structure, originally designed for easy disassembly, becomes significantly less flexible due to dust accumulation. When users attempt to disassemble the dust cup, they need to exert considerable force to overcome the resistance caused by the dust inside the latch, and may even damage vacuum cleaner components due to improper force.

[0006] On the other hand, dust accumulation can also accelerate wear on the clips. Fine dust particles rub against the clip surface during dust cup installation and removal, eventually roughening the surface and further affecting the ease of disassembly. Simultaneously, wear reduces the lifespan of the clips, increasing the vacuum cleaner's maintenance costs.

[0007] Therefore, it is necessary to improve existing technologies to overcome their shortcomings. Utility Model Content

Example

[0037] See Figures 1-7 As shown, a dust cup assembly structure includes a dust cup 2 and a body 1, with the dust cup 2 and body 1 connected by a snap-fit ​​structure. A sealing ring 3 is provided at the connection between the dust cup 2 and the body 1. The sealing ring 3 is located below the snap-fit ​​structure and can prevent dust from the dust cup from entering the gap of the snap-fit ​​structure. This structure not only ensures the normal operation of the snap-fit ​​structure and prevents dust accumulation at the snap-fit ​​structure, extending its service life, but also ensures that the vacuum cleaner maintains good sealing during operation, ensuring stable and efficient dust collection.

[0038] In this embodiment, the snap-fit ​​structure consists of slots 22 and buckles 12. Multiple slots 22 are distributed circumferentially along the inner wall of the dust cup 2, and buckles 12 correspond to the slots 22 and are mounted on the body 1. When the dust cup 2 is installed, rotating it counterclockwise causes the buckles 12 to snap into the slots 22; when the dust cup 2 is removed, rotating it clockwise causes the buckles 12 to disengage from the slots 22. This circumferentially distributed snap-fit ​​method can withstand greater external forces, improving the overall strength of the assembly structure. Furthermore, the snap-fit ​​and disengagement method, achieved by rotating the dust cup 2, is simple and intuitive, allowing users to complete the operation without complex tools, further enhancing the product's usability.

[0039] like Figures 4-7 As shown, the slot 22 consists of an opening 221, a first slot body 222, and a second slot body 223. The upper end of the first slot body 222 is connected to the opening 221, providing a channel for the buckle 12 to enter the slot. One side of the first slot body 222 is connected to the second slot body 223, and the bottom surface of the first slot body 222 and the bottom surface of the second slot body 223 are on the same plane, ensuring the stability of the structure. The second slot body 223 has a protrusion 24, and the dust cup above it has a stop part 23, which serves to further fix it. The width of the buckle 12 is smaller than the width of the opening 221, which facilitates the buckle 12 to enter the slot 22 smoothly. The buckle 12 has a plug part 121 that inserts into the second slot body, and the plug part 121 has a notch 122 corresponding to the protrusion 24. When dust cup 2 is installed, rotate the dust cup counterclockwise. The clip 12 enters the first groove 222 through the slot 221 and then slides into the second groove 223. At this time, the protrusion 24 engages with the notch 122 on the insertion part to achieve a secure connection. When it is necessary to disassemble dust cup 2, rotate the dust cup clockwise. The insertion part 121 separates from the protrusion 24, and the clip 12 disengages from the slot 22, making the operation convenient. This structural design ensures the stability of the connection between the dust cup and the body while facilitating the user's installation and disassembly operations.

[0040] Furthermore, the end of the stop part 23 has a first guide surface 231. This first guide surface 231 plays an important guiding role in the dust cup assembly process. When installing the dust cup, the dust cup 2 is rotated counterclockwise, and the latch 12 on the body 1 approaches the dust cup 2. At this time, the first guide surface 231 at the end of the stop part 23 can guide the latch 12 to enter the second groove 223 more smoothly.

[0041] Similarly, the end of the insertion part 121 on the buckle has a second guide surface. When the dust cup is installed, as the dust cup is rotated counterclockwise, the insertion part 121 approaches the second groove 223 of the slot 22. At this time, the second guide surface allows the insertion part 121 to be inserted into the second groove 223 more smoothly. It effectively reduces possible jamming and obstruction during the insertion process, ensuring a smooth installation process. With the second guide surface, users can easily achieve accurate alignment between the insertion part 121 and the second groove 223 without having to painstakingly adjust the angle and position when installing the dust cup.

[0042] In this embodiment, the combined use of the first guide surface 231 and the second guide surface makes it possible for the buckle 12 to enter the slot 22 without requiring the user to make excessive fine adjustments, which greatly improves the ease of installation.

[0043] In this embodiment, the dust cup 2 has an outwardly protruding bump 21, and a slot 22 is provided on the inner wall of the bump 21. This design makes the position of the slot 22 more reasonable, facilitates connection with the buckle 12 of the body, and also enhances the structural strength of the dust cup, providing a strong guarantee for the stable assembly of the dust cup.

[0044] A baffle 11 is provided on the body 1 above the latch 12, matching the protrusion 21. When the dust cup 2 is installed on the body 1, the baffle 11 is located directly above the protrusion 21 and covers the upper surface of the protrusion 21. The application of the baffle 11 effectively prevents dust from accumulating at the latching structure, avoiding potential impacts on the connection stability. Furthermore, the baffle 11 provides additional protection for the connection between the dust cup 2 and the body 1, reducing the impact of external factors on the connection area, such as preventing damage to the connection structure from accidental collisions. Simultaneously, the presence of the baffle 11 also makes the overall appearance of the vacuum cleaner cleaner cleaner and more aesthetically pleasing, improving the overall quality of the product.

[0045] In this embodiment, a sealing ring groove is provided on the body 1 below the buckle 12. The sealing ring 3 is set in the sealing ring groove, making its position more stable and reliable. When the dust cup 2 is installed on the body 1, the inner wall of the dust cup 2 will be tightly pressed against the sealing ring 3. Through the application of the sealing ring groove, the shape and sealing performance of the sealing ring 3 can be better maintained, ensuring good sealing between the dust cup 2 and the body 1, and effectively preventing dust in the dust cup from entering the gaps of the snap-fit ​​structure.

[0046] Correspondingly, an annular limiting groove is provided on the dust cup 2 below the slot 22, and the limiting groove corresponds to the position of the sealing ring groove; when the dust cup is installed on the body, the outer edge of the sealing ring 3 is pressed into the limiting groove. The application of the limiting groove makes the pressing action of the sealing ring 3 more stable and firm, and even if vibration occurs during the operation of the vacuum cleaner, the sealing ring can always maintain a good sealing state.

[0047] This utility model also proposes a handheld vacuum cleaner, including a body, a suction head and a dust cup, wherein the dust cup 2 and the body 1 adopt the dust cup assembly structure described above.

[0048] According to this utility model of a handheld vacuum cleaner, when cleaning a surface, the suction head exerts a powerful suction effect, quickly drawing dust into the dust cup. At this time, the sealing ring 3 plays a crucial role. Due to the obstruction of the sealing ring 3, dust from the dust cup 2 cannot enter the snap-fit ​​structure. Without the protection of the sealing ring, dust would easily accumulate at the snap-fit ​​structure, eventually leading to dust accumulation. Once dust accumulates at the snap-fit ​​structure, it not only affects the connection stability between the dust cup and the body but may also make it difficult to smoothly install and disassemble the snap-fit ​​structure. With the effective obstruction of the sealing ring 3, the snap-fit ​​structure is ensured to always remain clean and tidy, unaffected by dust from the dust cup 2. In this way, whether in daily cleaning work or when the dust cup needs to be disassembled for cleaning, users can operate the handheld vacuum cleaner more easily and conveniently, enjoying an efficient and stable cleaning experience.
