Description

Technical Field

[0001] The utility model relates to the technical field of air filter elements, in particular to a quickly detachable air filter element. Background Art

[0002] Air filters are generally installed in various devices that need to inhale air and prevent dust from entering, and they play the role of filtering out dust and sand in the air.

[0003] Publication No. (CN218553509U) discloses an air filter element that is easy to disassemble and replace, and relates to the field of air filter elements. The air filter element is intended to solve the technical problem that the current air filter element is very troublesome to disassemble and assemble when it is damaged and needs to be repaired. The air filter element comprises a No. 1 filter element housing, a No. 2 filter element housing arranged below the No. 1 filter element housing, and a fixing sleeve arranged above the No. 1 filter element housing and below the No. 2 filter element housing. One end of the fixing sleeve away from the No. 1 filter element housing and the No. 2 filter element housing is fixedly connected to a tightening ring with an external thread, and deformation grooves are equidistantly provided on the outer wall of the tightening ring. A fastening ring is threadedly connected to the outer side of the tightening ring. The air filter element adopts a combined structure of the No. 1 filter element housing and the No. 2 filter element housing, which is tightened by twisting external bolts, so that it is convenient and quick to install and disassemble. After separation from each other, the internal filter layer can be cleaned and maintained or the corresponding damaged filter element assembly can be replaced. It is flexible and convenient to use.

[0004] The above-mentioned public patent is complicated to operate when disassembling and replacing the filter element, and the staff needs to rotate the corresponding shell several times. The shell is fixed by a thread groove and fixed by a thread. After long-term use, the thread slippage phenomenon is very likely to occur, resulting in the inability to install and disassemble the filter element, which is inconvenient for the staff to use. For this reason, we propose a quickly disassembled air filter element. Utility Model Content

DETAILED DESCRIPTION

[0021] 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.

[0022] Example: Refer to Figure 1-4 A quickly detachable air filter element comprises an end cover 3, a filter element assembly is arranged at the bottom of the end cover 3, a mounting shell 8 is arranged at the top of the end cover 3, two symmetrically distributed fixed shells 9 are fixedly connected to the inner wall of the mounting shell 8, the fixed shell 9 is in a rectangular shape, a first sliding assembly is arranged inside the fixed shell 9, a snap-on assembly is arranged inside the fixed shell 9, a connecting plate 14 is fixedly connected to the top of the end cover 3, and a second sliding assembly is arranged on the top of the connecting plate 14.

[0023] Specifically, the filter element assembly includes a prismatic protective net 2 fixedly connected to the bottom of the end cover 3, the bottom of the prismatic protective net 2 is fixedly connected to the bottom cover 1, and the top of the bottom cover 1 is fixedly installed with a filter element body 4.

[0024] Specifically, the first sliding assembly includes a telescopic sleeve 10 fixedly mounted on one side of the inner wall of the fixed shell 9, and a telescopic rod 11 is slidably connected inside the telescopic sleeve 10. The trapezoidal block 13 can slide by setting the first sliding assembly.

[0025] Specifically, the snap-on assembly includes a trapezoidal block 13 fixedly connected to one side of the telescopic rod 11, a spring 12 is provided on one side of the trapezoidal block 13, the other end of the spring 12 is fixedly connected to one side of the inner wall of the fixed shell 9, and the spring 12 is sleeved on the outside of the telescopic rod 11 and the telescopic sleeve 10. By setting the snap-on assembly, the end cover 3 can be installed on the outside of the mounting shell 8.

[0026] Specifically, the second sliding component includes a sliding rod 5 fixedly connected to the top of the connecting plate 14, the top of the sliding rod 5 is fixedly connected to the second arc block 7, the outside of the sliding rod 5 is slidingly connected to the first arc block 6, and the first arc block 6 is located at the bottom of the second arc block 7. By setting up the second sliding component, the first arc block 6 can slide on the outside of the sliding rod 5.

[0027] Specifically, the first arc block 6 and the second arc block 7 are adapted to the trapezoidal block 13 . Since the first arc block 6 and the second arc block 7 are adapted to the trapezoidal block 13 , the trapezoidal block 13 can slide outside the first arc block 6 and the second arc block 7 .

[0028] The first step: when the filter element body 4 needs to be installed on the mounting shell 8, first push the end cover 3 to the inside of the mounting shell 8. At this time, the arc surface of the second arc block 7 will contact the inclined surface of the trapezoidal block 13, so that the second arc block 7 can be moved on the trapezoidal block 13. The telescopic rod 11 slides inside the telescopic sleeve 10, and the spring 12 is squeezed. The trapezoidal block 13 will move to the bottom of the second arc block 7. At this time, the spring 12 rebounds and pushes the trapezoidal block 13 to the outside of the slide rod 5. Since the bottom of the second arc block 7 is a plane, the trapezoidal block 13 cannot move in the direction of the second arc block 7 and is clamped on the outside of the first arc block 6 and the second arc block 7.

[0029] Step 2: When the filter element body 4 needs to be disassembled, the end cover 3 is pushed further toward the mounting shell 8. At this time, the inclined surface of the trapezoidal block 13 will contact the end surface of the first arc block 6, and the telescopic rod 11 slides inside the telescopic sleeve 10. The spring 12 is squeezed. At this time, the trapezoidal block 13 will move to the bottom of the first arc block 6, and then the end cover 3 is pulled in the opposite direction. Since the first arc block 6 slides on the outside of the slide rod 5, when the end cover 3 moves in the opposite direction, it drives the first arc block 6 to slide on the outside of the slide rod 5 and move toward the second arc block 7. At this time, the first arc block 6 is in contact with the second arc block 7, so that the trapezoidal block 13 can pass through the second arc block 7, and the spring 12 rebounds to complete the disassembly operation.

[0030] The above structure is convenient for the staff to quickly install and disassemble the filter element body 4 and the fixed shell 9. The installation and disassembly operations are simple. The installation and disassembly operations can be completed by pushing and pulling the end cover 3, which takes a short time and reduces unnecessary workload for the staff, greatly facilitating the use of the staff.
