The present invention relates to a dust collector, and more particularly to a filter cylinder having a dust cleaning device of a dust collector.
In the workplace where chips or dust are prone to occur, such as a woodworking plant, there is usually a dust collector used for maintaining the quality of the air and cleaning the environment. The dust collector collects chips and dust in the workplace to avoid chips and dust flying in the air so as to ensure the safety of the workplace and to facilitate the follow-up cleaning.

However, the above-mentioned conventional filter 4 is a High-Efficiency Particulate Air (HEPA) filter, which is capable of filtering dust of PM2.5. A filtration film is attached to the inner wall of the filter 4. When the flap member 7 is rapidly rotated to flap the filter 4, the filtration film on the inner wall of the filter 4 is liable to be damaged and the filtering effect of the filter 4 is lowered. As a result, the service life of the filter 4 is shortened. Accordingly, the inventor of the present invention has devoted himself based on his many years of practical experiences to solve these problems.
The primary object of the present invention is to provide a filter cylinder having a dust cleaning device of a dust collector to enhance the structural strength of a filter and to protect a filtration film on the inner wall of the filter.
In order to achieve the aforesaid object, a filter cylinder having a dust cleaning device of a dust collector is provided. The dust collector includes the filter cylinder. The filter cylinder has a cylindrical outer frame. A high-efficiency particulate air (HEPA) filter is provided inside the filter cylinder. The filter is in the form of a cylinder. An outer peripheral wall of the filter is formed with a plurality of zigzag edges. An inner peripheral wall of the filter is formed with zigzag tips corresponding to the zigzag edges. A cleaning device is axially provided in the filter cylinder. The cleaning device includes a main shaft. The main shaft is transversely provided with at least one bracket. Two ends of the bracket are each provided with a flap member. An upper end of the main shaft is provided with a handle. The cleaning device is driven to rotate in the filter cylinder by the handle. At least one tab is disposed in the filter cylinder. One end of the tab has a fixed portion fixed to a corresponding one of the zigzag tips of the filter. Another end of the tab has a movable portion extending toward the flap member to be in contact with the flap member.
When the flap member is rotated, one end of the flap member flaps the movable portion of the tab to vibrate the filter so that the dust adsorbed to the filter drops from the filter to enhance the structural strength of the filter and to protect the filtration film on the inner wall of the filter and to prolong the service life of the filter.
Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.

The outer circumferential wall of the main body 10 is provided with an air inlet 11. The air inlet 11 is connected with a dust collection tube 200 for allowing dust to enter the main body 10. Both ends of the main body 10 are formed with a first air outlet 12 and a second air outlet 13, respectively.
The dust collection cylinder 20 is connected with the first air outlet 11 of the main body 10 for storing dust falling from the man body 10.
The filter cylinder 30 is connected with the second air outlet 13 of the main body 10. The filter cylinder 30 has a cylindrical outer frame 31. A filter 32 is provided inside the filter cylinder 30. The filter 32 is a high-efficiency particulate air (HEPA) filter. A filtration film is attached to the inner wall of the filter 32. The filter 32 is capable of filtering out dust of PM2.5. The filter 32 is in the form of a cylinder. An outer peripheral wall of the filter 32 is formed with a plurality of zigzag edges 33, and an inner peripheral wall of the filter 32 is formed with zigzag tips 34 corresponding to the zigzag edges 33, thereby enhancing the effect of filtering dust.
The tab 40 has a fixed portion 41 at one end thereof. The fixed portion 41 is fixed to a corresponding one of the zigzag tips 34 of the filter 32. The fixed portion 41 has a Y-like shape for the fixed portion 41 to be fixed to a corresponding one of the zigzag tips 34 of the filter 32. Another end of the tab 40 has a movable portion 42 extending toward the center of the filter cylinder 30. The fixed portion 41 is fixed to a corresponding one of the zigzag tips 34 of the filter 32 by bonding.
The cleaning device 50 is disposed in the filter cylinder 30. The cleaning device 50 is located at the center of the filter cylinder 30. The cleaning device 50 includes a guide rod 51 and at least one bracket 52. The bracket 52 is transversely disposed on the guide rod 51. Two ends of the bracket 52 are each provided with a flap member 53. One side of the flap member 53 corresponds to the tab 40. The cleaning device 50 further includes a handle 54. The handle 54 is fixedly disposed on the top of the guide rod 51.
The exhauster 60 is disposed above the main body 10. The exhauster 60 includes a motor 61. The motor 61 is connected with a fan 62 to form an air flow in the main body 10.
