According to a further embodiment of the present invention, the outer frame of the first outer filter portion, the outer frame of the second outer filter portion, and the outer connection portion 14 are integrally formed, and the inner frame of the first inner filter portion, the frame of the second inner filter portion, and the inner connection portion 24 are integrally formed, i.e., the first outer frame 11, the second outer frame 12, and the outer connection portion 14 are integrally formed using an elastic material, and the first inner frame 21, the second inner frame 22, and the inner connection portion 24 are integrally formed using an elastic material.
Thereby, when the outer filter member 10 and the inner filter member 20 are in the closed state, the first outer frame 11, the second outer frame 12, and the outer connecting portion 14 are elastically deformed, and the first inner frame 21, the second inner frame 22, and the inner connecting portion 24 are elastically deformed; when it is necessary to open the outer filter member 10 and the inner filter member 20, the first outer frame 11, the second outer frame 12, and the outer connecting portion 14 can be restored, and the first inner frame 21, the second inner frame 22, and the inner connecting portion 24 can be restored. In addition, the integrated into one piece's structure can improve the structural strength and the stability of external filter piece 10 and internal filter piece 20, saves the connecting piece, improves production efficiency.
According to one embodiment of the present invention, a handle 221 is provided on a side of the second inner filter portion remote from the inner connection portion 24, so that it is suitable for a human hand to disengage the second inner filter portion from the second outer filter portion.
Specifically, when needing to clean external filter element 10 and internal filter element 20, can lift up the second internal filter portion through handle 221, make the anticreep recess 26 of second internal filter portion break away from the cooperation with the anticreep arch 16 of second external filter portion, make separation of second internal filter portion and second external filter portion, easy operation, it is clean convenient.
In some examples, the side of the second inner frame 22 of the second inner filter portion facing away from the second outer filter portion is provided with a handle 221 to accommodate a human hand to disengage the anti-slip groove 26 from the anti-slip protrusion 16. Further, a handle 221 is provided on a side of the second inner frame 22 of the second inner filter portion away from the inner connection portion 24.
According to an embodiment of the present invention, the first outer filter portion is provided with a first latching portion 171 at a position far from the outer connecting portion 14, and the second outer filter portion is provided with a second latching portion 172 at a position far from the outer connecting portion 14, so that the side of the first outer filter portion far from the outer connecting portion 14 and the side of the second outer filter portion far from the outer connecting portion 14 are latched by the first latching portion 171 and the second latching portion 172, and the outer filter member 10 and the inner filter member 20 are locked in the closed state.
And, when the outer filter member 10 is in the closed state, the position of the outer filter member 10 where the first and second catching portions 171 and 172 are provided forms the top of the filter 100, the first and second inner filter portions define the passage 202 therebetween, and the top of the filter 100 is provided with a plurality of ventilation holes 102 arranged at intervals. When the filter 100 is in use, air enters through the plurality of air vents 102, and air entering the channel 202 is sequentially filtered by the inner filter screen and the outer filter screen and finally discharged to the outside, so that the filtering effect is good.
In some examples, the first catching portion 171 is provided at a position of the outer frame of the first outer filter portion (i.e., the first outer frame 11) away from the outer connection portion 14, and the second catching portion 172 is provided at a position of the outer frame of the second outer filter portion (i.e., the second outer frame 12) away from the outer connection portion 14.
In some examples, the first positioning portion 171 and the second positioning portion 172 may form a mutually-matched protrusion, which is simple in structure and reliable in matching, and when the filter 100 needs to be opened, the first positioning portion 171 and the second positioning portion 172 can be separated only by slightly pulling the filter by a human hand.
One specific embodiment of a filter 100 according to an embodiment of the present invention is described in detail below.
As shown in fig. 1, the filter 100 includes an outer filter member 10 and an inner filter member 20, the outer filter member 10 including a first outer filter portion and a second outer filter portion, the first outer filter portion being connected by an outer connecting portion 14 made of a flexible elastic material and the second outer filter portion, and the inner filter member 20 including a first inner filter portion and a second inner filter portion, the first inner filter portion being connected by an inner connecting portion 24 made of a flexible elastic material and the second inner filter portion.
When the filter 100 needs to be opened to clean the burrs, the outer filter element 10 and the inner filter element 20 can be opened simultaneously, specifically, the first inner filter portion of the inner filter element 20 slides in the guide groove 15 of the first outer filter portion through the guide post 25, so that the phenomenon that the burrs fly due to the fact that the inner filter element 20 suddenly bounces under the effect of the inner connecting portion 24 when the filter 100 is opened to clean the burrs is avoided.
As shown in fig. 2 and 3, after the filter 100 is completely opened to clean the inner filter screen, the anti-falling protrusion 16 of the second outer filter portion is separated from the anti-falling groove 26 of the second inner filter portion, and then the inner filter member 20 is turned inside the guide groove 15 by the guide post 25, and the inner filter member 20 is turned to one side, so that the outer filter member 10 can be cleaned.
As shown in fig. 5-7, the second inner filtering portion of the inner filtering member 20 is provided with an anti-falling protrusion 16, the second outer filtering portion of the outer filtering member 10 is provided with an anti-falling groove 26 engaged with the anti-falling protrusion 16, and when the filter 100 is closed, the anti-falling protrusion 16 is engaged with the anti-falling groove 26, so that the inner filtering member 20 and the outer filtering member 10 are tightly attached to increase the sealing performance between the inner zero-crossing outer filtering member 10; the engagement of the retaining projection 16 and the retaining groove 26 prevents the second inner filter portion of the inner filter member 20 from being separated from the second outer filter portion when the filter 100 is opened.
