Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, and in particular to a pulse back-blowing type industrial vacuum cleaner. Background Technology

[0002] Driven at high speed by an electric motor, the impeller of a vacuum cleaner blower expels air from the impeller at high speed, continuously replenishing the intake fan with air from the suction section. This creates a high pressure difference with the outside environment, drawing dust and dirt from the nozzle into the suction section along with the air. The dust and dirt are then filtered and collected in the dustbin. The filtered air is then discharged from the rear of the machine. Industrial-grade vacuum cleaners are large-scale cleaning equipment specifically designed for industrial production, manufacturing, warehousing and logistics, and engineering construction.

[0003] Existing pulse jet industrial vacuum cleaners collect dust using dust bags, which are typically secured to the device with fastening rings and threads. When workers need to fix the dust bag, they must repeatedly operate the fastening rings and threads to tighten them and secure the bag. Because the fastening and threading process is cumbersome and time-consuming, workers cannot easily replace the dust bag. Therefore, it is necessary to design a pulse jet industrial vacuum cleaner that allows for easy dust bag replacement, thus saving workers considerable time when changing dust bags. Utility Model Content

A suction pipe is connected to one side of the vacuum cleaner, and a connecting pipe is connected to the top of the vacuum cleaner. A discharge hopper is connected to the end of the connecting pipe furthest from the vacuum cleaner. An electromagnetic pulse valve is installed on the top of the discharge hopper. The bottom of the discharge hopper is fixed to a dust bag via a quick-connect fitting. The quick-connect fitting includes a rotating plate, a pressure block, a compression sleeve, a support plate, and a spring. The rotating plate is connected to the side wall of the discharge hopper via a torsion spring shaft. A pressure block is fixedly connected to the bottom edge of the rotating plate. A compression sleeve is movably connected to the outer wall of the rotating plate. A support plate is fixedly connected to the side wall of the discharge hopper, and the support plate and the compression sleeve are connected to each other via a spring.

[0006] Preferably, the number of rotating plates is set to multiple, and the multiple rotating plates are arranged in a ring at equal intervals with the discharge hopper as the center.

[0014] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 This utility model provides a technical solution: like Figure 1-4 As shown, a pulse-jet industrial vacuum cleaner includes a base 1, on which a vacuum cleaner 2 is mounted. A suction pipe 3 is connected to one side of the vacuum cleaner 2, and a connecting pipe 4 is connected to the top of the vacuum cleaner 2. A discharge hopper 5 is connected to the end of the connecting pipe 4 furthest from the vacuum cleaner 2. An electromagnetic pulse valve 6 is mounted on the top of the discharge hopper 5. The bottom of the discharge hopper 5 is fixed to a dust bag 7 via a quick-connect fitting. The quick-connect fitting includes a rotating plate 8, a pressure block 9, a compression sleeve 10, a support plate 11, and a spring 12. The side wall of the discharge hopper 5 is connected to the rotating plate 8 via a torsion spring shaft. A pressure block 9 is fixedly connected to the bottom edge of the rotating plate 8. After the rotating plate 8 rotates in conjunction with the pressure block 9, it can squeeze and fix the dust collection bag 7. A squeezing sleeve 10 is movably connected to the outer wall of the rotating plate 8. The bottom of the squeezing sleeve 10 is provided with an inclined surface. After the inclined surface at the bottom of the squeezing sleeve 10 moves downward, it will squeeze the rotating plate 8 to rotate. A support plate 11 is fixedly connected to the side wall of the discharge hopper 5. The support plate 11 and the squeezing sleeve 10 are connected to each other by a spring 12. The spring 12 will push the squeezing sleeve 10 to move downward, so that the squeezing sleeve 10 firmly squeezes the rotating plate 8.

[0016] like Figure 3 and Figure 4As shown, multiple rotating plates 8 are arranged in a ring around the discharge hopper 5 at equal intervals. These rotating plates 8 can compress and fix the dust collection bag 7 from multiple angles, thus improving the fixing effect. A latch 13 is provided on the side wall of the discharge hopper 5, which is compatible with the pressure block 9. The pressure block 9, in conjunction with the latch 13, further enhances the fixing effect of the dust collection bag 7. A limiting plate 14 is fixedly connected to the bottom of the support plate 11. The limiting plate 14 ensures that the compression sleeve 10 can only move vertically up and down. The compression sleeve 10 is slidably connected to the outer wall of the limiting plate 14. A baffle 15 is fixedly connected to the bottom of the limiting plate 14. The cross-sectional area of ​​the baffle 15 is larger than that of the limiting plate 14. The baffle 15 can limit the compression sleeve 10 when it moves downwards, thus preventing the compression sleeve 10 from completely separating from the limiting plate 14. A steel ring 16 is fixedly connected to the top of the dust collection bag 7. The steel ring 16 not only facilitates the connection of the port of the dust collection bag 7 to the bottom of the discharge hopper 5, but also works with the pressure block 9 to prevent the dust collection bag 7 from completely detaching from the discharge hopper 5 when it slides down. A horizontal handle 17 is fixedly connected to the outer wall of the steel ring 16, which makes it easy for the operator to push the dust collection bag 7 upward. A through groove 18 is provided on the side wall of the extrusion sleeve 10, which can prevent the extrusion sleeve 10 from being blocked by the horizontal handle 17 when it moves downward.

[0017] Working Principle: When the dust bag 7 needs to be replaced, the operator first grasps the squeezing sleeve 10 and pushes it upward. The squeezing sleeve 10 will no longer squeeze the rotating plate 8. The rotating plate 8 will rotate through the torsion spring shaft after losing its limit. The rotating plate 8 will drive the pressure block 9 to move out of the inside of the bayonet 13. In this way, the dust bag 7 will be unsecured, and the operator can remove the dust bag 7 from the bottom of the discharge hopper 5. Then, the operator pushes the steel ring 16 through the horizontal handle 17 to put the new dust bag 7 on the bottom of the discharge hopper 5. Then, the operator releases the squeezing sleeve 10, and the spring 12 will push the squeezing sleeve 10 downward to reset. In this way, the inclined surface of the squeezing sleeve 10 will squeeze the rotating plate 8 to rotate. The rotating plate 8 will drive the pressure block 9 to rotate, and the pressure block 9, along with part of the dust bag 7, will be inserted into the inside of the bayonet 13. In this way, the new dust bag 7 can be fixed at the bottom of the discharge hopper 5, so that the operator can easily replace the dust bag 7 without wasting too much time.

[0018] In summary, when the staff needs to replace the dust collection bag 7, the staff only needs to push the squeezing sleeve 10 upward. The rotating plate 8 will lose its squeezing and reset through the torsion spring shaft. In this way, the dust collection bag 7 will be unfixed, and the staff can remove the old dust collection bag 7 and put the new dust collection bag 7 on the bottom of the discharge hopper 5. Then the staff releases the squeezing sleeve 10, and the spring 12 will push the squeezing sleeve 10 to reset. The squeezing sleeve 10 will push the rotating plate 8 to rotate, and the rotating plate 8 will cooperate with the pressure block 9 to squeeze and fix the dust collection bag 7, so that the staff can easily replace the dust collection bag 7.
