[0025] Example 1: Refer to Figures 1-4 A nail vacuum cleaner, applicable in the field of vacuum equipment technology, includes a main housing 6, the top of which is securely fixed with a top cover 10 by a second bolt 9. Inside the top cover 10, an air inlet is designed for sucking up dust generated during the nail art process. To optimize airflow guidance, a guide flange 11 is also fixed inside the top cover 10 by a third bolt 12; this guide flange 11 is precisely positioned inside the air inlet.
[0026] Inside the main housing 6, a central drawer housing 7 is fixed, and a rear end plate 8 is connected to the rear end of the central drawer housing 7. The central drawer housing 7 is equipped with two sets of U-shaped guide rails, which are used for sliding installation of the dust collection drawer 2 and the filter drawer 3, respectively. A dust inlet, connected to the guide flange 11, is formed between the dust collection drawer 2 and the central drawer housing 7, allowing the sucked-in dust to smoothly enter the dust collection drawer 2.
[0027] The central drawer housing 7 and the rear sealing plate 8 work together to divide the interior of the main housing 6 into two areas: a vacuum chamber and an exhaust chamber. The dust collection drawer 2 and the filter drawer 3 are both located in the vacuum chamber, while the filter drawer 3 is connected to both the dust collection drawer 2 and the exhaust chamber, ensuring that dust is filtered before being discharged.
[0028] Inside the filter drawer 3, a filter screen 5 is fixed. A set of vibration components for cleaning the filter screen 5 is installed inside the rear sealing plate 8. The vibration components include a vibration motor mounting bracket 26 fixed inside the rear sealing plate 8, and a miniature vibration motor 25 fixed inside the vibration motor mounting bracket 26. The output end of the miniature vibration motor 25 intermittently contacts the bottom end of the filter drawer 3. The vibration of the miniature vibration motor 25 cleans the filter screen 5, reducing the frequency of filter screen cleaning and effectively reducing workload. Only periodic cleaning of the dust collection drawer is required, making it convenient to use. The filter screen 5 is made of carbon-filled filter element, which can effectively filter out fine particles in dust. An EC centrifugal blower is installed in the exhaust chamber. The blower includes a blower housing 15 fixed to the main housing 6 by a fourth bolt 17. An EC centrifugal motor partition 16 is connected to the bottom end of the blower housing 15, and an EC centrifugal motor 14 is fixed on the partition. An EC motor suction fan 13 is connected to the output end of the EC centrifugal motor 14, and they are all located inside the blower housing 15. The air inlet of the EC centrifugal blower is connected to the exhaust chamber, while its exhaust outlet is connected to the exhaust slot 24 opened inside the main casing 6.
[0029] To enhance the equipment's sealing performance, box sealing strips 23 are fixed to the sides of the upper cover plate 10 and the main housing 6 to effectively seal the gap between them. Simultaneously, O-ring seals 22 are also fixed between the upper cover plate 10 and the guide flange 11 to further prevent airflow leakage. Two drawer openings inside the main housing 6 are used for sliding installation of the dust collection drawer 2 and the filter drawer 3, respectively. Sealing cotton is installed on the side of the rear sealing plate 8 and inside the two sets of guide rails to ensure that dust does not leak from these areas.
[0030] To facilitate user operation, both the dust collection drawer 2 and the filter drawer 3 are equipped with handles 1 on their sides. These two handles 1 are securely fixed to the sides of the dust collection drawer 2 and the filter drawer 3 by the first bolt 4.
[0031] Example 2: Refer to Figures 1-4 An improvement upon Embodiment 1: A triangular power input socket 18 is fixed to the side end of the main housing 6 by a fifth bolt 19 for power input. A power switch 20 and a speed control potentiometer 21 are fixed to the front end of the main housing 6. The triangular power input socket 18 is electrically connected to the power switch 20, which is electrically connected to the EC centrifugal motor 14, which in turn is electrically connected to the speed control potentiometer 21, thereby enabling adjustment of the suction power.
[0032] The external power cord is connected to the triangular power input socket 18. The output terminal of the triangular power input socket 18 is connected to the input terminal of the power switch 20. The output terminal of the power switch 20 is connected to the input wire of the EC centrifugal motor 14. After being processed by the internal circuit of the EC centrifugal motor 14, the output +10V and -10V power are connected to the speed control potentiometer 21. The output voltage signal of the speed control potentiometer 21 is fed back to the EC centrifugal motor 14 by adjusting the size of the potentiometer by rotating it left and right, thereby controlling the suction power of the vacuum.
[0033] However, as is well known to those skilled in the art, the working principles and wiring methods of the miniature vibration motor 25, the EC centrifugal motor 14, the triangular power input socket 18, and the speed control potentiometer are commonplace and belong to conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.
[0034] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
