Detailed Description

The present invention will be described in further detail by way of examples with reference to the accompanying drawings, which are illustrative of the present invention and are not intended to limit the present invention.

Example 1

As shown in fig. 1 to 3, the filter device comprises a first end cover 101 and a second end cover 102, wherein a central mounting hole 103 is formed in the first end cover 101, a tubular connecting frame 104 for connecting the two end covers is arranged between the first end cover 101 and the second end cover 102, a filter paper core 105 which is made of filter paper and has a tubular structure is arranged around the outer side of the tubular connecting frame 104, one end of the filter paper core 105 abuts against the inner side wall of the first end cover 101, a first clamping component for clamping the other end of the filter paper core on the second end cover 102 is arranged between the other end of the filter paper core and the second end cover 102, and at least one of the two ends of the tubular connecting frame 104 and the corresponding first end cover 101 and second end cover 102 is detachably connected.

Because the two ends of the cylindrical connecting frame 104 and at least one of the first end cover 101 and the second end cover 102 corresponding to the two ends are detachably connected, the filter paper element 105 can be firstly installed on the cylindrical connecting frame 104 during installation, and then the cylindrical connecting frame 104 is connected with the first end cover 101 and/or the second end cover 102 detachably connected with the cylindrical connecting frame 104.

Here, there are many detachable connection manners, for example, two ends of the cylindrical connection frame 104 and the corresponding first end cap 101 and second end cap 102 may be clamped or screwed, the clamping manner is that at least one of the first end cap 101 and second end cap 102 is provided with a clamping groove (not shown in the drawings) for clamping one end of the cylindrical connection frame 104, as shown in fig. 2 to 3, the screwing manner is that an annular connection seat 112 is convexly provided at the center on the inner end surface of the first end cap 101 and second end cap 102, the inner side of the connection seat 112 is provided with an internal thread, and two ends of the cylindrical connection frame 104 shown in fig. 4 are provided with external threads corresponding to the internal threads one by one, that is, the detachable connection is realized by the screwing manner, and of course, other detachable manners may be adopted according to needs.

Specifically, as shown in fig. 5, the first clamping assembly includes a first clamping seat 106 in threaded engagement with an inner side of a lower edge portion of the second end cap 102, the first clamping seat 106 is provided with a first circular bayonet 107 for inserting and clamping the other end of the filter paper core 105, and the shape of the first circular bayonet 107 is the same as the shape of the cross section of the other end of the filter paper core 105, and the size of the first circular bayonet is slightly smaller than the size of the cross section of the other end of the filter paper core 105.

When the filter paper core 105 is installed, the first clamping seat 106 is installed on the second end cover 102, then the other end of the filter paper core 105 sleeved on the cylindrical connecting frame 104 is inserted into the first circular bayonet 107, and since the other end of the first circular bayonet 107 is slightly smaller than the cross section of the other end of the filter paper core 105, after the filter paper core 105 is inserted, the other end of the filter paper core 105 is outwards expanded to keep a certain pressure between the outer side of the filter paper core and the inner side of the first circular bayonet 107, so that the other end of the filter paper core 105 can be tightly clamped on the first circular bayonet 107.

Preferably, a first sealing gasket 108 abutting against the end face of the other end of the filter paper core 105 is arranged between the first clamping seat 106 and the second end cover 102.

When the cylindrical connecting frame 104 is installed, the other end of the filter paper core 105 sleeved on the cylindrical connecting frame 104 is inserted into the first annular bayonet 107 and is connected with the first sealing gasket 108 in an abutting mode, so that the sealing performance of the cylindrical connecting frame 104 is enhanced.

In addition, a first sealing groove matched with the cross section shape and size of the other end of the filter paper core 105 is formed in one side, which is abutted against the filter paper core 105, of the first sealing gasket 108.

When the filter paper core is installed, the other end of the filter paper core 105 is only required to be installed in alignment with the first sealing groove, so that the other end of the filter paper core 105 and the first sealing gasket 108 can be further prevented from moving in the application process, and the sealing performance of the filter paper core is improved.

It should be noted that, contrary to the operation procedure during the installation, during the disassembly, the cylindrical connecting frame 104 can be separated from the first end cap 101 and the second end cap 102 detachably connected thereto, and then the filter paper core 105 sleeved on the cylindrical connecting frame 104 can be taken out from the end of the cylindrical connecting frame 104 separated from the first end cap 101 or the second end cap 102, and further, since dust is accumulated on the first end cap 101, the second end cap 102 and the first clamping seat 106 and the first sealing gasket 108 of the first clamping assembly after a period of use of the filter device, the first clamping seat 106 can be detached from the second end cap 102, the first sealing gasket 108 can be taken out, and the filter paper core 105 and other components can be cleaned, dried and then reassembled.
