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 first zigzag tips corresponding to the zigzag edges. A cleaning device is axially provided in the filter cylinder. The cleaning device includes a guide rod and a bracket. Two ends of the bracket are each provided with a flap member. An upper end of the guide rod is provided with a handle. The cleaning device is driven to rotate in the filter cylinder by the handle. At least one collar is disposed on an inner wall of the filter cylinder and corresponds in position to the flap member. The collar is formed with second zigzag tips corresponding to and attached to the first zigzag tips. One end of the flap member is located between two of the second zigzag tips.
When the guide rod is rotated by the handle, the flap member is rotated in the filter cylinder to flap the collar and further to vibrate the filter so that dust adsorbed to the filter drops from the filter. The present invention can enhance the structural strength of the filter and protect the filtration film on the inner wall of the filter and 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.
As shown in
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. Upper and lower 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 first zigzag tips 34 corresponding to the zigzag edges 33, thereby enhancing the effect of filtering dust.
The collar 40 is disposed in the filter 32 of the filter cylinder 30. The collar 40 is in a circular shape. The collar 40 is formed with second zigzag tips 41 corresponding to the first zigzag tips 34. The collar 40 is fixed to 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. The flap member 53 corresponds in position to the collar 40, and is located between two of the second zigzag tips 41.
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.

The filter cylinder 30 is provided with the filter 32 which is able to filter out dust of PM2.5. The filtration film is attached to the inner peripheral wall of the filter 32. The inner peripheral wall of the filter 32 is formed with the first zigzag tips 34 for increasing the area of the filter 32 to adsorb dust. The second zigzag tips 41 of the collar 40 correspond to the first zigzag tips 34 of the filter 32. The second zigzag tips 41 and the first zigzag tips 34 are secured to each other by bonding. The collar 40 is made of resilient anti-abrasive paper to enhance the structural strength of the filter 32, so that when the flap member 53 flaps the collar 40, the filtration film on the inner wall of the filter 32 won't be damaged, thereby prolonging the service life of the filter 32.
Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
