[0026] Example 1
[0027] Please see Figs. 1-2The present invention provides a technical solution: a vacuum cleaner HEPA cleaning structure, including a motor base 1 with a plurality of mounting slots 2, a motor 3 mounted on the motor base 1, a dust removal pusher 4 mounted in the mounting slots 2, a push plate 5 at the bottom of the dust removal pusher 4, an air damper 6 located between two of the push plates 5, and a filter 7 located at the bottom of the air damper 6.
[0028] Specifically, see Figs. 1-2 A pressure sensor 8 is provided on the motor base 1, and the pressure sensor 8 is connected to the control unit of the dust removal actuator 4 via wired / wireless means.
[0029] The present invention provides a HEPA filter cleaning structure for a vacuum cleaner. This structure features a rotatable, openable damper on the vacuum cleaner body. A dust removal actuator controls the opening and closing of the damper. When a pressure sensor detects negative pressure caused by dust clogging the filter, it sends a signal to the dust removal actuator. The control unit then controls the actuator to open and close the swing-type damper. When one damper is closed, the other opens. With the damper open, the negative pressure between the filter and the vacuum motor draws air from outside the vacuum cleaner body through a reverse airflow inlet on the dust removal actuator, blowing away and clearing a large amount of dust from the filter, thus restoring suction power. The closed damper on the other side normally guides dust into the HEPA filter and discharges it through the outlet. This structure effectively improves dust collection efficiency, avoids the problems caused by existing technologies that rely on pulling up and down brushes and vibrations that affect filter performance, and improves motor lifespan and indoor air quality.
[0030] Therefore, this embodiment has the following advantages compared to the prior art:
[0031] A new HEPA filter cleaning structure for vacuum cleaners solves the problem that the HEPA filter of current vacuum cleaners is prone to clogging due to the accumulation of dust and fine particles after long-term use. Clogging not only reduces the suction power of the vacuum cleaner, but also affects the life of the motor and indoor air quality. Existing technologies use pull-out brushes and high-frequency vibration to clean the filter, but the cleaning effect is poor.
[0032] Example 2:
[0033] See Figs. 1-2 The figure shows a HEPA cleaning structure for a vacuum cleaner according to Embodiment 2 of the present invention. Based on the above embodiments, this embodiment further improves upon the following technical solution: the bottom of the push plate 5 is located at the bottom of the air damper 6, facilitating the opening and closing of the air damper by the push plate.
[0034] Example 3:
[0035] See Figs. 1-2The figure shows a HEPA cleaning structure for a vacuum cleaner according to Embodiment 3 of the present invention. Based on the above embodiments, this embodiment further improves upon the following technical solution: the damper 6 is rotatably connected to the rotating shaft 9, which is connected to the bottom of the motor base 1 and located on top of the filter 7. This improves the stability of the entire cleaning structure.
[0036] Example 4:
[0037] See Figs. 1-2 The figure shows a vacuum cleaner HEPA cleaning structure provided in Embodiment 4 of the present invention. Based on the above embodiments, this embodiment further improves upon the following technical solution: a connecting ear 10 is provided on the motor base 1, and the rotating shaft 9 is connected to the connecting ear 10. This allows both side dampers to be rotatably connected to the rotating shaft.
[0038] Example 5:
[0039] See Figs. 1-2 The figure shows a vacuum cleaner HEPA filter cleaning structure provided in Embodiment 5 of the present invention. Based on the above embodiments, this embodiment further improves upon the following technical solution: a reverse airflow inlet 11 is provided inside the vacuum cleaner body, located outside the dust removal actuator 4. By opening the damper, the negative pressure inside the vacuum cleaner draws external airflow into the vacuum cleaner. The airflow passes through the open damper to the top of the filter, blowing away dust from the top of the filter, and then exits through the outlet. For a closed damper, external airflow enters normally, passes through the HEPA filter, and then exits through the outlet.
[0040] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
