[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 6 This utility model provides a technical solution: a dust collector filter bag with anti-damage function, including a dust collector filter bag body 1, a limiting ring 21 and a filter screen 49. A connecting mechanism 2 is provided on the upper side of the dust collector filter bag body 1, and the limiting ring 21 is connected to the upper side of the dust collector filter bag body 1. A protective mechanism 3 is connected to the lower end of the connecting mechanism 2, and the protective mechanism 3 is located on the side of the dust collector filter bag body 1. A damage warning mechanism 4 is connected to the lower end of the connecting mechanism 2, and the filter screen 49 is connected to the lower end of the connecting mechanism 2. The damage warning mechanism 4 is located below the dust collector filter bag body 1.

[0025] The connecting mechanism 2 includes a soft rubber pad 22, a connecting ring 23, and a connecting shell 24. The soft rubber pad 22 is provided inside the limiting ring 21. The connecting ring 23 is threadedly connected to the upper side of the dust collector filter bag body 1. The connecting shell 24 is connected to the side of the connecting ring 23. The inner ring of the soft rubber pad 22 is set as a ring with the same diameter as the outer ring of the dust collector filter bag body 1. The soft rubber pad 22 fits against the outer wall of the dust collector filter bag body 1. The connecting shell 24 is set above the limiting ring 21. First, the filter screen 49 is removed. Then, the connecting ring 23 is threadedly connected to the side of the dust collector filter bag body 1. During the threading process of the connecting ring 23, the soft rubber pad 22 is squeezed to improve the sealing of the connection. At the same time, the connecting shell 24 is installed on the side of the dust collector filter bag body 1.

[0026] The protective mechanism 3 includes a first protective frame 31, a first magnetic ring 32, a second protective frame 33, a second magnetic ring 34, and a connecting rod 35. The lower end of the limiting ring 21 is provided with the first protective frame 31. The first magnetic ring 32 is equidistantly connected to the sides of the first protective frame 31. The inner side of the dust collector filter bag body 1 is provided with the second protective frame 33. The sides of the second protective frame 33 are equidistantly provided with the second magnetic ring 34. The inner side of the second protective frame 33 is provided with the connecting rod 35. The inner circle of the first protective frame 31 has the same diameter as the outer circle of the dust collector filter bag body 1, and the first protective frame 31 is located on the outside of the dust collector filter bag body 1. The outer circle of the second protective frame 33 has the same diameter as the inner circle of the dust collector filter bag body 1, and the second protective frame 33 is located on the inside of the dust collector filter bag body 1. The second magnetic ring 34 is attracted to the first magnetic ring 32. During use, after the connecting ring 23 is installed, the second protective frame 33 is installed inside the dust collector filter bag body 1, and the second magnetic ring 34 is magnetically connected to the first magnetic ring 32. This protects the dust collector filter bag body 1 during use and prevents it from being damaged. When the second protective frame 33 needs to be removed, the connecting rod 35 is pulled to cause the second magnetic ring 34 on the side of the second protective frame 33 to lose its magnetic attraction with the first magnetic ring 32, which facilitates the quick removal of the second protective frame 33. When the dust collector filter bag body 1 needs to be replaced, the limiting ring 21 is rotated to de-thread from the dust collector filter bag body 1, which allows for quick replacement.

[0027] The damage warning mechanism 4 includes a rotating column 41, a limiting plate 42, a propeller blade 43, a housing 44, a sliding rod 45, and a connecting block 46. The filter screen 49 is rotatably connected to the rotating column 41. The limiting plate 42 is provided at the lower end of the rotating column 41. Propeller blades 43 are arranged at equal angles on the sides of the rotating column 41, and are positioned above the filter screen 49. The housing 44 is symmetrically arranged on the sides of the rotating column 41. The sliding rod 45 is slidably connected to the housing 44. The sliding rod 45 passes through the side wall of the housing 44 and is connected to the connecting block 46. A spring hook 410 is provided inside the housing 44 and connects to the sliding rod 45. Connecting blocks 46 are symmetrically arranged inside the connecting shell 24. Plate 47, with a bell 48 connected to its lower end. During normal use, the filtered gas from the dust collector filter bag body 1 flows to the inside of the connecting shell 24 and then to the propeller blade 43, causing the propeller blade 43 to rotate slightly. When the dust collector filter bag body 1 is damaged, the gas flow speed increases, causing the propeller blade 43 to rotate rapidly. During the rotation of the propeller blade 43, the centrifugal force increases, thereby causing the slide rod 45 to slide out. As the slide rod 45 extends, it causes the connecting block 46 to strike the bell 48, thus making a sound to remind the staff that the dust collector filter bag body 1 needs to be replaced in time due to damage.

[0028] Working principle: According to Figures 1 to 6 First, remove the filter screen 49. Then, thread the connecting ring 23 to the side of the dust collector filter bag body 1. During the threading process of the connecting ring 23, squeeze the soft rubber pad 22 to improve the sealing of the connection. At the same time, install the connecting shell 24 on the side of the dust collector filter bag body 1. After installing the connecting ring 23, install the second protective frame 33 into the dust collector filter bag body 1. At the same time, magnetically connect the second magnetic ring 34 and the first magnetic ring 32 to protect the dust collector filter bag body 1 during use and prevent damage. When it is necessary to remove the second protective frame 33, pull the connecting rod 35 to cause the second magnetic ring 34 on the side of the second protective frame 33 to lose magnetic attraction with the first magnetic ring 32, so as to facilitate quick removal of the second protective frame 33. The filtered gas flows to the inside of the connecting shell 24 and then to the propeller blade 43, causing the propeller blade 43 to rotate slightly. When the dust collector filter bag body 1 is damaged, the gas flow speed increases, which in turn causes the propeller blade 43 to rotate rapidly. During the rotation of the propeller blade 43, the centrifugal force increases, thereby causing the slide rod 45 to slide out. As the slide rod 45 extends, it causes the connecting block 46 to strike the bell 48, thus emitting a sound to remind the staff that the dust collector filter bag body 1 needs to be replaced in time. When the dust collector filter bag body 1 needs to be replaced, the limiting ring 21 is rotated to de-thread from the dust collector filter bag body 1, so that it can be replaced quickly. The above is the working process of the entire device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
