Abstract
Description
Technical Field
[0001] This utility model belongs to the field of HEPA vacuum cleaner technology, and particularly relates to a HEPA vacuum cleaner with a self-cleaning structure. Background Technology
[0002] Vacuum cleaners are essential tools for modern household and industrial cleaning. The performance of their core filtration element—the high-efficiency particulate air (HEPA) filter (commonly known as "HEPA")—directly affects the device's suction efficiency and lifespan. Traditional HEPA filters are made of high-density fiber materials. While they can effectively capture fine particles (such as PM2.5, pollen, and dust mites), dust and impurities easily accumulate on the surface of the HEPA filter during long-term use, leading to the following problems: 1. Increased airflow resistance: Dust accumulation can clog the filter pores, increasing airflow resistance, reducing the vacuum cleaner's suction power, and forcing a higher motor load. This not only increases energy consumption but may also shorten the motor's lifespan; 2. Frequent maintenance requirements: Users need to manually clean or replace the filter regularly, which is cumbersome and may cause secondary pollution (such as dust). For industrial scenarios or frequently used household vacuum cleaners, maintenance costs are significantly increased; 3. Incomplete cleaning: Traditional cleaning methods such as beating and washing can easily damage the filter fiber structure, while air-blowing backflushing technology often fails to completely remove deeply attached particles, affecting the filter's reusability.
[0003] In existing technologies, some solutions attempt to improve the filter screen by using washable filter media or electrostatic adsorption. However, the drying time after washing is long and the electrostatic materials are prone to failure. Therefore, neither of these solutions can effectively clean HEPA filters. Utility Model Content
[0004] This invention overcomes the shortcomings of the prior art by providing a vacuum cleaner HEPA with a self-cleaning structure to solve the problems existing in the prior art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a vacuum cleaner HEPA filter with a self-cleaning structure is installed inside a vacuum cleaner. The vacuum cleaner HEPA filter includes a HEPA filter body and a vibration assembly located inside the HEPA filter body. The HEPA filter body is provided with a first bracket and a second bracket. The HEPA filter body is installed inside the vacuum cleaner through the first bracket and the second bracket. The vibration assembly includes a vibration motor and an eccentric wheel. The eccentric wheel is located at the end of the vibration motor and is driven by the vibration motor. The eccentric wheel drives the HEPA filter body to vibrate.
[0006] In a preferred embodiment of the present invention, a mounting bracket is provided inside the HEPA body, and the mounting bracket mounts the vibration motor inside the HEPA body.
[0007] In a preferred embodiment of this utility model, the vibration motor is embedded in the mounting bracket, the fixed end of the vibration motor corresponds to the position of the first bracket, and the driving end corresponds to the position of the second bracket.

[0010] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0017] The following drawings will disclose several embodiments of this utility model. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these physical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.
[0018] Furthermore, in this utility model, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the utility model. They are merely used to distinguish components or operations described with the same technical terms and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
[0019] This embodiment provides a vacuum cleaner HEPA filter with a self-cleaning structure, which is installed inside the vacuum cleaner 100. The vacuum cleaner HEPA filter can perform rapid self-cleaning. It uses a vibration motor 21 to drive an eccentric wheel 22, causing the HEPA filter to vibrate, thereby causing the impurities attached to the HEPA filter to fall off quickly, achieving effective cleaning of the HEPA filter. Its structure is simple and practical, and has strong stability, which will not affect the normal use of the HEPA filter.
[0020] Combination Figures 1 to 3 As shown, the HEPA vacuum cleaner of this embodiment includes a HEPA body 10 and a vibration assembly 20 located inside the HEPA body 10. The HEPA body 10 is provided with a first bracket 30 and a second bracket 40. The HEPA body 10 is installed inside the vacuum cleaner 100 through the first bracket 30 and the second bracket 40. The vibration assembly 20 includes a vibration motor 21 and an eccentric wheel 22. The eccentric wheel 22 is located at the end of the vibration motor 21 and is driven by the vibration motor 21. The eccentric wheel 22 drives the HEPA body 10 to vibrate. During the long-term operation of the vacuum cleaner 100, a large amount of dust and other impurities will accumulate on the HEPA body 10. When it is necessary to clean the impurities, the vibration motor 21 of the vibration assembly 20 is started, driving the eccentric wheel 22 to rotate at high speed, thereby causing the HEPA body 10 to vibrate. The HEPA body 10 in the vibrating state can remove the dust and impurities on its surface, causing the impurities attached to the HEPA body 10 to fall off, thus achieving effective cleaning of the HEPA body 10.
[0021] In this embodiment, a mounting bracket 50 is provided inside the HEPA body 10. The mounting bracket 50 mounts the vibration motor 21 inside the HEPA body 10. The vibration motor 21 is embedded in the mounting bracket 50. The fixed end of the vibration motor 21 corresponds to the position of the first bracket 30, and the driving end corresponds to the position of the second bracket 40. The HEPA body 10 is mounted under the cooperation of the first bracket 30 and the second bracket 40, and the vibration motor 21 is mounted under the action of the mounting bracket 50, so that the vibration motor 21 drives the HEPA body 10 to vibrate through the eccentric wheel 22.
[0022] Furthermore, in this embodiment, the first bracket 30 and the second bracket 40 are respectively located at both ends of the HEPA body 10 to install the HEPA body 10. The HEPA body 10 has a wide end and a narrow end. The eccentric wheel 22 is located at the narrow end of the HEPA body 10. When the vibration motor 21 drives the eccentric wheel 22, since the eccentric wheel 22 is located at the narrow end of the HEPA body 10, the eccentric wheel 22 can smoothly drive the HEPA body 10 to vibrate, thereby realizing the self-cleaning operation of the HEPA body 10.
[0023] In this embodiment, the self-cleaning HEPA vacuum cleaner has a self-cleaning structure. In actual use, the vibration motor 21 and the eccentric wheel 22 form a self-cleaning structure for the HEPA body 10. When a large amount of dust and impurities accumulate on the HEPA body 10, after the HEPA body 10 is removed, the vibration motor 21 drives the eccentric wheel 22, which drives the HEPA body 10 to vibrate, causing the dust and impurities on the HEPA body 10 to fall off, thereby completing the self-cleaning process of the HEPA body 10.
