[0005] 1. In the above structure, the connecting plate and the threaded seat are connected and fixed by the screw thread of the screw rod. Therefore, each disassembly and assembly requires manually screwing the screw rod, which is time-consuming and laborious, and there is a probability of thread slipping, increasing the difficulty of disassembly and assembly.

[0006] Therefore, it is necessary to provide a new quick-opening filter to solve the above technical problems. Content of the Utility Model

The quick-opening filter includes: a filter barrel 1, a barrel cover 2, a sealing ring 3, a filter element 4, two first mounting blocks 5, two second mounting blocks 6 and two connection mechanisms. The barrel cover 2 is arranged above the top of the filter barrel 1, and the barrel cover 2 is adapted to the filter barrel 1. The sealing ring 3 is arranged on the bottom of the barrel cover 2, and the sealing ring 3 is adapted to the filter barrel 1. The filter element 4 is arranged in the filter barrel 1, and the top of the filter element 4 extends above the top of the filter barrel 1, passes through the sealing ring 3 and is detachably connected to the bottom of the barrel cover 2. Two first mounting blocks 5 are symmetrically mounted on the outer wall of the filter barrel 1, two second mounting blocks 6 are symmetrically mounted on the outer wall of the barrel cover 2, and the two first mounting blocks 5 and the two second mounting blocks 6 are connected by two connection mechanisms;

[0024] The connection mechanism includes a hollow insertion cylinder 7, a fixing ring 8, a plurality of limiting blocks 9, a plurality of limiting sliders 10 and an extrusion column 11, and the inner holes on the hollow insertion cylinder 7 and the fixing ring 8 are communicated.

[0025] The second mounting block 6 is provided with a first mounting hole, the hollow insertion cylinder 7 is fixedly installed on the first mounting hole, the fixing ring 8 is fixedly installed on the top of the second mounting block 6, and the top end of the hollow insertion cylinder 7 is fixedly connected to the bottom of the fixing ring 8.

[0026] A plurality of through openings are provided in the lower half of the hollow insertion cylinder 7, and a plurality of limiting blocks 9 are installed on the plurality of through openings through torsion springs. The limiting blocks 9 are adapted to the through openings and the inner hole of the hollow insertion cylinder 7.

The first mounting block 5 is provided with a second mounting hole, the second mounting hole is adapted to the hollow insertion cylinder 7, and a plurality of limiting chutes are provided on the inner wall of the second mounting hole. The limiting chutes are adapted to the limiting sliders 10.

[0028] The extrusion column 11 is adapted to the inner holes of the fixing ring 8 and the hollow insertion cylinder 7, and an electric push rod 13 is installed on the top of the barrel cover 2.

[0029] An installation frame 12 is installed on the output shaft of the electric push rod 13, and the installation frame 12 is fixedly connected to the two extrusion columns 11.

[0030] This application makes partial changes and innovations to the technical solution of the document with the publication number CN 217092427 U, and other structures remain unchanged. The connection method between the barrel cover 2 and the filter element 4 can adopt the technical solution in CN 217092427U.

[0031] The working principle of the quick-opening filter provided by the utility model is as follows:

[0032] The first step: During installation, the first mounting block 5 is in contact and fit with the second mounting block 6. Then, the electric push rod 13 is started, and the installation frame 12 is driven to move downward through the electric push rod 13. Further, the two extrusion columns 11 are driven to move downward through the installation frame 12, so that the bottom of the installation frame 12 contacts the top of the fixing ring 8, causing the extrusion columns 11 to pass through the inner hole of the fixing ring 8 and insert into the inner hole of the hollow insertion cylinder 7 to squeeze the plurality of limiting blocks 9, causing the plurality of limiting blocks 9 to pass through the through openings and contact the bottom of the first mounting block 5 (as Figure 3 shown) to form limit fixation for the first mounting block 5 and the second mounting block 6;

[0033] Second step: When disassembling, the electric push rod 13 drives the mounting bracket 12 to move upward, and then the mounting bracket 12 drives the two extrusion columns 11 to move upward and disengage from the two fixing rings 8. After that, under the lack of the extrusion effect of the extrusion columns 11, the limit stop block 9 will enter the through port due to the reset of the torsion spring. When the bucket lid 2 moves away from the filter bucket 1, the second mounting block 6 will drive the hollow insertion cylinder 7 to disengage from the first mounting block 5, thereby completing the disassembly work, making the operation simple. It can not only solve the problem that the disassembly and assembly process is time-consuming and laborious due to the use of screw connection and fixation, but also solve the problem that the disassembly and assembly difficulty is increased due to the probability of thread slipping.
