[0022] The utility model is now described in further detail in conjunction with the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0023] Please refer to Figure 1-7 , a portable filter bag replacement support device comprises a support component 1 and a filter bag 5 above the support component 1, the support component 1 comprises an upper support ring 11 and a lower support ring 12, the upper support ring 11 and the lower support ring 12 are connected by an oblique support rod 14, an arc-shaped support plate 13 is arranged in the lower support ring 12, the periphery of the filter bag 5 is in contact with the upper support ring 11 and the lower support ring 12, the bottom of the filter bag 5 is in contact with the surface of the arc-shaped support plate 13, and a shock-absorbing and resetting mechanism is arranged under the arc-shaped support plate 13; when in use, dust in the filter bag 5 accumulates at the bottom and is supported by the support component 1 and the arc-shaped support plate 13 to prevent the filter bag 5 from being damaged by excessive weight; in addition, since a shock-absorbing and resetting mechanism is arranged under the arc-shaped support plate, it can play a shock-absorbing role in the dust filtering process and is convenient for replacing the filter bag.

[0024] Specifically, the shock absorbing reset mechanism includes a support rod 2 and a fixed tube 3, the support rod 2 is plugged and connected to the fixed tube 3, a base 4 is provided at the bottom of the fixed tube 3, a spring 33 is provided inside the fixed tube 3, one end of the spring 33 is fixed on the base 4, and the other end is fixed on the support rod 2, and the support component 1 floats in the fixed tube 3 through the support rod 2 and the spring 33.

[0025] When in use, the filter bag and the dust inside can press the support rod downward as a whole through their own gravity, which plays a shock-absorbing role when in use; when the filter bag needs to be replaced, the old filter bag is removed and replaced with a new one. After the old filter bag is removed and replaced, the whole body bounces upward and resets, so that the filter bag moves upward for easy connection, which is very practical.

[0026] In order to facilitate the smooth compression and reset of the support rod 2 and the whole, a strip-shaped limiting protrusion 21 is provided on the outer wall of the support rod 2 along its own length direction, and the inner wall of the fixed tube 3 is provided with a limiting groove matching the limiting protrusion. During the compression and reset process, the support rod 2 moves up and down along the limiting groove through the limiting protrusion 21.

[0027] In order to increase the overall stability, a plurality of movable legs are further provided under the arc-shaped support plate 13, and the movable legs include a universal ball 131, a sleeve 132 and an insertion rod 133. The universal ball 131 is provided on the lower surface of the arc-shaped support plate 13, one end of the sleeve 132 is fixed on the universal ball 131, and the other end is sleeved with the insertion rod 133, and the sleeve 132 and the insertion rod 133 are fixed by a connecting bolt 134; since one end of the sleeve 132 is connected to the universal ball 131, it can be explained that the sleeve 132 can adjust the support angle at will through the universal ball; when supporting and using, the length of the insertion rod 133 is adjusted so that its end supports the ground, which can increase the overall stability. For details, please refer to Figure 8 .

[0028] In addition, a lock plate 31 is provided on the circumference of the fixing cylinder 3, and a plurality of lock buckles 32 are provided on the circumference of the lock plate 31. The plug-in rod 133 cooperates with the lock buckle 32 after being folded. Please refer to Figure 8 When not in use, the plug-in rod 133 can be folded into the lock to prevent it from swinging randomly and affecting normal use.

[0029] The filter bag will inevitably be installed and replaced during use. In order to improve the installation and replacement efficiency, a connecting ring 51 is provided at the top port of the filter bag 5. A wire 52 and a built-in elastic band 53 are provided inside the connecting ring 51. Both ends of the wire 52 extend outward through the connecting ring 51. The port of the filter bag 5 is fixed on the dust outlet tube 6. The outer wall of the dust outlet tube 6 is provided with an annular limiting groove 61. The filter bag 5 is connected to the dust outlet tube at the annular limiting groove 61 through the wire 52 and the elastic band 53. When in use, the filter bag 5 is first collapsed on the dust outlet tube 6 through the elastic band 53 to preliminarily fix it, and then the wire extending outward can be tightened, which can greatly improve the tightness and installation efficiency of the filter bag and prevent it from falling off during filtering and dust removal. Similarly, when disassembling, you only need to loosen the wire and pull it out.

[0030] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
