DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-5 The utility model provides a technical solution: a self-cleaning dust removal filter bag device, including a filter bag shell 1, an exhaust pipe 2 is installed through one end of the filter bag shell 1, a vacuum pump 21 is installed on the exhaust pipe 2, a hollow joint 4 is installed at one end of the filter bag shell 1, a flat suction nozzle 41 is provided at one end of the hollow joint 4 through a movable plug-in, a fixing ring 61 is installed on the inner wall of the filter bag shell 1, a filter bag 6 is connected to one side of the fixing ring 61, and the vacuum pump 21 in the filter bag shell 1 sucks air into the device through the connection of the exhaust pipe 2. The air containing dust flows into the filter bag shell 1 through the hollow joint 4, and when the air flows through the filter bag 6, the solid particles are captured by the filter bag, and the clean air is discharged through the exhaust pipe 2, which plays a role in separating the solid particles. The flat suction nozzle 41 is used to better fit the ground to achieve the dust collection effect;

[0021] The top of the filter bag shell 1 is fixed with a fixing frame 3 by welding, and a motor 31 is installed on the top of the fixing frame 3. The output end of the motor 31 is connected to a rotating shaft 311 through a coupling, and one end of the rotating shaft 311 is sleeved with a driving wheel 312. The inner wall of the hollow joint 4 is rotatably installed with a hollow rotating shaft 51, and one end of the hollow rotating shaft 51 is sleeved with a driven wheel 5. A transmission belt 32 is connected between the driving wheel 312 and the driven wheel 5. The motor 31 drives the coupling through its output end to transmit power to the rotating shaft 311, and drives the sleeved one through its rotation. The driving wheel 312 at the end rotates, and the torque is transmitted through the transmission belt 32. When the motor 31 is running, the rotation of the driving wheel 312 drives the driven wheel 5 to rotate at the same time, thereby driving the rotation of the hollow shaft 51. The position of the hollow shaft 51 is maintained by the hollow joint 4. One end of the hollow shaft 51 is in contact with the inner wall of the flat suction nozzle 41. Under normal circumstances, the position of the hollow shaft 51 is maintained due to the obstruction of the bent flat suction nozzle 41. After the flat suction nozzle 41 is disassembled, the hollow shaft 51 loses the obstruction and can be removed smoothly.

[0022] A U-shaped groove is correspondingly opened at the top of the hollow joint 4, and the transmission belt 32 movably passes through the U-shaped groove. When cleaning, the transmission belt 32 can pass through the U-shaped groove to facilitate power transmission without affecting dust removal. When the hollow shaft 51 needs to be disassembled, first remove the flat suction nozzle 41 from the hollow joint 4, pinch the driven wheel 5 by hand and pull it out, and the U-shaped groove is not to block the removal;

[0023] The outer wall of the hollow rotating shaft 51 is provided with long holes 52 distributed in a circumferential manner, and an inner tube 55 is fixedly installed on the inner wall of the hollow rotating shaft 51. The outer wall of the inner tube 55 is provided with vent holes distributed in a circumferential manner, and the outer wall of the vent hole is screwed with an air nozzle 56, and a flexible folded bag 53 is installed on one side of the air nozzle 56. The flexible folded bag 53 is connected with the vent hole through the air nozzle 56, and one end of the flexible folded bag 53 extends into the interior of the long hole 52. When self-cleaning is required, gas is pumped into the hollow rotating shaft 51 so that air enters the flexible folded bag 53 through the air nozzle 56 to expand it. The flexible folded bag 53 will be squeezed outward from the long hole 52, and will contact the inner wall of the filter bag 6 as the hollow rotating shaft 51 rotates. The rotation will make the contact more comprehensive, so that the particles are swept down from the inner wall of the filter bag 6.

[0024] The outer wall of the flexible folded capsule 53 is fixed with a polyvinyl alcohol film layer 54 by bonding, and the particles and dust inside the filter bag 6 are bonded by the polyvinyl alcohol film layer 54, so that the polyvinyl alcohol can form a strong and adhesive film, and after the flexible folded capsule 53 is expanded, it is attached to the inner wall of the filter bag 6 for self-cleaning;

[0025] When the driven wheel 5 is pulled and the flexible folded bag 53 is pulled out of the hollow joint 4, the flexible folded bag 53 will be deformed and fill the inner wall of the hollow joint 4, clean the dust on the inner wall, and take out the dust in the reverse direction. After being taken out, the flexible folded bag 53 can be washed and cleaned, and the air in the flexible folded bag 53 can be drained and inserted into the interior of the hollow shaft 51, or the air nozzle 56 can be directly unscrewed to replace a new flexible folded bag 53;

[0026] The driven wheel 5 is a hollow structure, and an air pump 7 is movably provided on one side of the driven wheel 5. The detachable air pump 7 is used as an inflation source to facilitate inflation. The air pump 7 can be taken away during normal use without affecting the normal vacuuming work. When inflation is needed, the air outlet end of the air pump 7 is connected to the driven wheel 5.

[0027] When using the utility model, the filter bag needs to be cleaned. The hollow shaft is driven to rotate by a motor, and the flexible folded bag is inflated. The polyvinyl alcohol film layer on its surface adheres to the inner wall of the filter bag, forming an effect of absorbing and adhering dust and particulate matter, thereby achieving a self-cleaning effect. There is no need to disassemble the entire shell to clean the filter bag every time. This cleaning method is suitable for daily cleaning. Some impurities stuck in the gaps of the filter bag still need to be disassembled and cleaned after being used many times.

[0028] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
