[0016] 2. The present invention uses the telescopic sleeve and the second spring to push the cover frame to automatically move downward when the second box body moves upward.

The collecting frame can be used to conveniently and stably transport and clean the collected dust, and can be reused. When the second box body moves downward to reset, the sealing plates on both sides can be pushed to automatically detach from the discharge pipe, completing automatic opening, thereby ensuring the stability of subsequent dust and impurity discharge and collection work, effectively improving the environmental protection of the pulse back-blowing vacuum cleaner, and at the same time further improving the practicality and convenience of the pulse back-blowing vacuum cleaner.

[0018] 4. The present invention controls the electromagnetic pulse valve through a pulse controller, and combined with an air compressor, it can deliver compressed air to each first blowing pipe. During the delivery process, the airflow can drive the guide fan blades to rotate automatically, and then drive the first blowing pipe to rotate automatically. At the same time, under the spiral guiding action of the first connecting pipe and the second connecting pipe, the stroke of the airflow can be increased, and the compressed gas can be jetted step by step through nozzles at different heights.

[0030] The specific implementation process of the present invention is as follows: first, the staff can push the pulse back-blowing vacuum cleaner by holding the fixed handle 24 on the first box body 4, and the pulse back-blowing vacuum cleaner can be easily moved by the universal wheels 10 on the bottom plate 1 until it moves to the working position, and then the turbine fan 15 on the first box body 4 is driven. The turbine fan 15 can perform negative pressure suction on the first box body 4 and the second box body 5 through the turbine fan 15. Under the action of the negative pressure suction force, the vacuuming work can be performed through the vacuum pipe 13 on the guide frame 11. At this time, the dust-containing gas enters the guide frame 11 through the vacuum pipe 13, and enters the first box body 4 and the second box body 5 through the guide groove 12 at the bottom of the guide frame 11. Then, the dust-containing gas can be filtered by the filter cartridge 18 and then transported to the fixed pipe 14 through the first through groove 17 on the connecting plate 16, and then discharged by the drive of the turbine fan 15 to complete the vacuuming work; During the operation of the vacuum cleaner, the pulse controller 713 controls the electromagnetic pulse valve 703 and the air compressor 701. The frequency of the pulse controller 713 is adjusted to control the number of jets per unit time of the electromagnetic pulse valve 703 and the air compressor 701 to back-blow the filter cartridge 18. After the electromagnetic pulse valve 703 and the air compressor 701 are turned on, the compressed gas is transported to each third air pipe 705 through the first air duct 702 and the second air duct 704, and then can be transported to each first blowing pipe 706. At this time, under the action of gas transportation, the airflow can drive the guide blades 712 to rotate automatically, and then the first blowing pipe 706 can be driven to rotate automatically. Then the compressed gas is first ejected through each nozzle 711 on the first blowing pipe 706, and then, under the guidance of the first connecting pipe 707, through the second blowing pipe Each nozzle 711 on the blow pipe 708 sprays out, and similarly, under the guidance of the second connecting pipe 709, each nozzle 711 on the third blow pipe 710 sprays out; in summary, under the spiral guidance of the first connecting pipe 707 and the second connecting pipe 709, the stroke of the airflow can be increased, and the step-by-step injection of compressed gas can be achieved through the nozzles 711 at different heights, and the automatic rotation of the first blow pipe 706 can drive the second blow pipe 708 and the third blow pipe 710 to rotate synchronously, and then drive each nozzle 711 to rotate stably, so that the upper, middle and lower parts of the filter cartridge 18 can be gradually and evenly pulse-jetted, so that the dust adhering to the outer side of the filter cartridge 18 is gradually separated from the top to the bottom, so as to achieve the effect of pulse back-blowing cleaning, which can effectively improve the cleaning effect of pulse back-blowing; During the operation of the vacuum cleaner, large particles of dust first enter the second box body 5 under the action of gravity, and fall into the collection frame 23 through the discharge pipe 911 for automatic collection, and the dust outside the filter cartridge 18 can also fall into the collection frame 23 through the discharge pipe 911 for automatic collection after pulse backblowing under the action of gravity. After the vacuum cleaner is finished working, the staff can drive the hydraulic rod 2, and at this time, the hydraulic rod 2 can drive the first box body 4 to move upward through the support plate 3, and then can drive the second box body 5 connected in the card to move upward synchronously; Under the movement of the second box body 5, the cover frame 904 can be driven to move upward and separate from the collection frame 23. At this time, under the elastic action of the second spring 903 inside the telescopic sleeve 902, the cover frame 904 can be pushed to move downward automatically. Under the movement of the cover frame 904, the slider 908 in the slide groove 906 can drive the sealing plate 909 to move downward synchronously. When the sealing plate 909 moves to the third through groove 912 on the discharge tube 911, under the elastic action of the third spring 907 inside the slide groove 906, the sealing plate 909 is moved downward to the third through groove 912 on the discharge tube 911. The sealing plate 909 can be pushed by the slider 908 to automatically engage in the third through groove 912 on the feed tube 911. At this time, under the engagement of the sealing plates 909 on both sides, combined with the first sealing strip 910 and the second sealing strip 913, the sealing and closing work of the feed tube 911 can be automatically completed, so as to prevent the dust inside the vacuum cleaner from continuously falling and polluting the environment during the cleaning process of the collected dust by the staff. At this time, the collected dust can be conveniently and stably transported and cleaned by using the collection frame 23, and can be reused; After the collection frame 23 is used, it can be put into the limit frame 22 again, and the first box body 4 and the second box body 5 can be driven by the hydraulic rod 2 to move downward and reset. At this time, under the action of the movement of the second box body 5, the cover frame 904 can be driven to move downward and contact the collection frame 23. At this time, under the blocking action of the collection frame 23, the cover frame 904 can move toward the second box body 5. At this time, under the relative movement of the cover frame 904 and the second box body 5, through the guidance of the inclined surface of the sealing plate 909, the cover frame 904 can push the sealing plate 909 to automatically move out of the third through groove 912 on the discharge pipe 911, so as to realize the automatic opening of the discharge pipe 911, thereby ensuring the stability of the subsequent dust and impurity collection work; After the vacuum cleaner is finished working, when the filter cartridge 18 needs to be replaced, it is only necessary to push the stopper 28 to move into the limiting rod 26 so that it will not be blocked by the positioning frame 29, and the disassembly and separation between the first box body 4 and the second box body 5 can be completed. At this time, the driving of the hydraulic rod 2 can only push the first box body 4 to move upward and separate from the second box body 5, and the second box body 5 does not move. At this time, under the action of the movement of the first box body 4, the pulse backflush assembly 7 can be driven to move away from the filter cartridge 18, and then the staff can take and place the filter cartridge 18 to replace the filter cartridge 18; After the filter cartridge 18 is replaced, it is only necessary to insert the positioning rod 21 on the bottom base 20 of the filter cartridge 18 into the positioning groove 803 on the air storage frame 802. Then, under the driving action of the hydraulic rod 2, the first box body 4 is driven to move downward and reset. At this time, the first box body 4 can push each filter cartridge 18 to move downward automatically through the connecting plate 16, and the filter cartridge 18 can use the positioning rod 21 to push the first piston 806 on the first spring 805 to move downward. At this time, the air in the air storage frame 802 can be transported to the first air supply pipe 807. In the second air delivery pipe 808, under the action of air pressure, the second piston 809 in the second air delivery pipe 808 can push the clamping plate 811 to move toward the middle through the plug rod 810. At this time, under the action of the movement of each clamping plate 811, the positioning rod 21 on the base 20 can be automatically clamped and fixed, so that the filter cartridge 18 on the base 20 can be automatically and stably clamped, fixed and positioned and installed, and the batch positioning and installation of the filter cartridge 18 can be automatically completed, ensuring the stability and safety of the subsequent working state of the filter cartridge 18; At the same time, the fixing plate 25 on the first box body 4 can drive the limiting rod 26 to automatically insert into the positioning frame 29 on the second box body 5, and under the guiding action of the inclined surface at the end of the block 28, the limiting rod 26 can drive the block 28 to automatically pass through the positioning frame 29, and the fourth spring 27 can be used to drive the block 28 to automatically move outward and reset. Combined with the limiting rod 26 and the positioning frame 29, the first box body 4 and the second box body 5 can be easily engaged and fixed to ensure the stability of the subsequent working state of the vacuum cleaner.
