Embodiment
Below with reference to accompanying drawing 1 to accompanying drawing 6 the utility model is described further, but this reality should not be limited with this
With new protection domain.
Referring to the drawings 1, a kind of filter element device, including casing assembly 1 and the filter core 2 that is arranged on the casing assembly 1 inside, this
Casing assembly 1 is used as forming receiving space, for the placement of filter core 2.
Reference picture 2 is to Fig. 4.
Casing assembly 1 includes casing 11 and is arranged on being accommodated with the casing 11 formation for the both ends of casing 11
Two cylinder covers 12 of the filter core 2；
Wherein, the periphery of each cylinder cover 12 sets an annular groove 121, two end edges tool of the casing 11
There is radially inwardly extending fixed part 111；When two cylinder covers 12 and casing 11 assemble, the card of fixed part 111 is set
The fixation of two cylinder covers 12 and casing 11 is realized in the annular groove 121.Detailed, the annular groove 121
Sectional view is rectangular configuration, and the end that the fixed part 111 has casing 11 caves inward what is formed.Specifically shaping when
Wait, the cylindrical shell of the casing 11, the cylinder cover 12 described in its inner side socket two, then again in the presence of external force,
The end of the casing 11 is recessed to the annular groove 121, forms described fixed part 111.On the one hand the technology makes
Fixed structure is obtained to simplify, it is on the other hand also more simple for assembling.
In the present embodiment, the circumferential lateral surface of each cylinder cover 12 and the inner face of the casing 11 are tightly connected.It is close
Envelope connection can take various forms and be sealed, the present embodiment, each cylinder cover 12 outer circumferential side at least provided with one the
One seal groove 122, sets the first sealing ring 3 in the first seal groove 122, and first sealing ring 3 is by cylinder cover 12 and casing
11 sealings.Specifically, devising two the first seal grooves 122, the first sealing ring is respectively provided with corresponding each first seal groove 122
3.First sealing ring 3 uses O-shaped structure, and is interference fitted with first seal groove 122.When the cylinder cover 12 and shell
