As shown in fig. 1-9, the present invention provides an embodiment of a quick release device with air filtration.

The quick isolating device with the air filtering function comprises a foldable isolating mechanism and an air filter, wherein the foldable isolating mechanism comprises a foldable cover and a folding frame which supports the foldable cover to form an isolating space, and the air filter is communicated with the isolating space formed by the foldable cover and the folding frame.

Specifically, the air filter comprises a filtering main body and a bleed air mechanism communicated with an air inlet of the filtering main body, the bleed air mechanism comprises a bleed air pipe for leading air into the filtering main body, and the bleed air pipe is provided with a first-stage filter; the filter body comprises a second-stage filter 2 and a third-stage filter 1 sleeved on the second-stage filter 2, a cover plate 5 is arranged on the end face of the second-stage filter 2 and the end face of the third-stage filter 1 on the same side, a through hole 51 is formed in the cover plate 5, the second-stage filter 2 is provided with an air inlet hole 20, an inclined plane 21 inclined from outside to inside is arranged at the air inlet end of the air inlet hole 20, a filtering decompression cavity B is formed between the inclined plane 21 and the cover plate 5, and the filtering decompression cavity B is communicated with the through hole 51 and the air inlet hole 20 in the cover plate 5 respectively.

In particular, when assembled, said filtering and pressure-reducing cavity B is located between the external air input and the air intake 20. Partial pressure reduction may be performed while the pressure is increased during filtration. One end of the air inlet hole 20 is closed, and the other end is communicated with an external air pipeline through a filtering decompression cavity B. The upper surface of the second stage filter 2 does not extend beyond the third stage filter surface after assembly. The stage filter 2 is provided with a cover plate 5 at the air inlet so that the filtering and filtering decompression cavity B forms a relatively closed structure.

Because the filtering body filtering decompression cavity formed by the inclined plane which inclines inwards is arranged at one side of the air inlet hole of the second-stage filter, the pressure difference of the second-stage filter can be reduced when air enters the air inlet hole 20.

Because the air inlet hole 20 has a certain depth, when air enters the air inlet hole 20, the air easily enters the second-stage filter 2 at a position close to the air inlet hole 20, the filter is locally effective for a long time, and the service life and the filtering effect are influenced. Therefore, it is possible to provide the gas dispersion mechanism 3, which uniformly delivers air to the inner surface of the intake hole 20 to disperse the filtering area, in the intake hole 20.

The gas dispersing mechanism 3 comprises a spiral disperser 3A positioned at the gas inlet end and a vertical disperser 3B connected with a surface guide groove of the spiral disperser 3A. The spiral disperser 3A comprises a conical body 30, such as a conical body, the surface of which is provided with a plurality of first spiral guide strips 31, and first spiral guide grooves 30 are formed between adjacent spiral guide strips 31. The vertical disperser 3B comprises a vertical dispersing main body and second spiral guide strips 33 arranged on the surface of the vertical dispersing main body, a second spiral guide groove 34 is formed between the adjacent second spiral guide strips 33, when the second spiral guide groove 34 is installed on the air inlet hole 20, a spiral channel 35 is formed on the inner surface of the air inlet hole 20, and the second spiral guide groove 34 is smoothly connected with the first spiral guide groove 30. The spiral disperser 3A is provided at its edge with an opening 32 connected to the first spiral guide groove 30, the opening 32 having a width corresponding to the width of the first spiral guide groove 30 and the second spiral guide groove 34. The ramp 21 is a seal structure, i.e. gas does not enter the second stage filter 2 from its surface. The shapes of the second stage filter 2 and the third stage filter 1 can be set according to requirements, and the second stage filter and the third stage filter adopt cylindrical structures such as cylinders in the embodiment.

In use, gas enters the filtering and pressure reducing cavity B from the direction F through the through hole 51 and the cover plate 5 to be reduced in pressure, and then spiral motion in the directions F1 and F2 is generated in the filtering and pressure reducing cavity B through the first spiral guide groove 30 on the spiral disperser 3A, and the gas enters the gas inlet holes 20 along the second spiral guide groove 34 and is uniformly dispersed to each position of the gas inlet holes 20 along the direction F3. Since gas is concentrated above the distance air inlet holes 20 at the beginning, and the pressure below the air inlet holes 20 is small, the gas is naturally guided to the lower part with small pressure, thereby forming a maximized filtering surface, enlarging the filtering area, and further improving the filtering efficiency, the service life and the filtering flow.

According to the needs, the edge of the second spiral guide strip 33 is provided with a protrusion 331 for guiding the liquid, the liquid which can be condensed on the second spiral guide strip 34 is guided to a collecting mechanism (not shown in the figures) through the protrusion 331, and the liquid is prevented from entering the second-stage filter 2, so that the filtering efficiency and the service life of the second-stage filter 2 are prevented from being affected.

On the basis of the above embodiments, another embodiment of the quick isolating device with an air filtering function is also provided.

As shown in fig. 9-11, the surface of the vertical disperser 3B is provided with a liquid separation screen 4, and gaps 36 are respectively provided between the liquid separation screen 4 and the side walls of the air inlet holes 20 and the vertical dispersing body, wherein the liquid separation screen 4 can separate the possibly existing liquid from the air, and the gaps 36 can prevent the separated liquid from entering the second stage filter 2, which affects the filtering efficiency and the service life. Other structures and specific principles are the same as those described above, and are not described in detail.

The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: it is to be understood that modifications may be made to the above-described arrangements in the embodiments or equivalents may be substituted for some of the features of the embodiments without departing from the spirit or scope of the present invention.
