Embodiment

Shown in as shown in Figure 1, Figure 2 and Figure 3~Fig. 4, the respectively structural representation of the utility model preferred embodiment and its hard Part block diagram, and various views during its use.As illustrated throughout the figures, confined space gas provided by the utility model Body exchange system 1 is used to the gas between a confined space 2 and the external world is swapped and filtered.Wherein the confined space 2 has There are an air inlet 21 and a gas outlet 22, the confined space gas exchange systems 1 provided by the utility model include an air inlet mould Block 11, an exhaust module 12 and a control module 13.

Wherein the air inlet module 11 is correspondingly arranged in the position of the air inlet 21 to be closed, and the air inlet module 11 wraps Containing an airscoop shroud 111, a bidirectional fan 112 and a filter material 113, in the present embodiment, the bidirectional fan 112 is located at the airscoop shroud 111 relative to the confined space 2 side, and by the filter material 113 located at the external world relatively of airscoop shroud 111 side, and then So that the air inlet runner 1111 for being internally formed closing of the airscoop shroud 111；It should be noted that wherein, the filter material 113 is extraction Formula, and the filter material 113 is coincided and formed by least one layer of active carbon material 1131 and at least one layer of special nano-fiber material 1132, As shown in FIG., the utility model is coincided structure using one layer of active carbon material 1131 and one layer of special nano-fiber material 1132 Into, certainly also can multiple kenels by staggeredly coincide in a manner of formed, its form when, the active carbon material 1131, which is arranged at, to be leaned on Extraneous side, the special nano-fiber material 1132 are located at the side by the confined space 2.Therefore, when the bidirectional fan 112 When just blowing, the dirty air of outside can be sucked inside the airscoop shroud 111, and first pass through the block of filter material 113 and filtered Air inlet, the utility model remove the peculiar smell in air by the active carbon material 1131, and the special nano-fiber material 1132 is then It is that can to adsorb suspension harmful in air dirty, such as：PM2.5, and it is piled up in the special nano-fiber material Between 1132 hole, so that the clean free from extraneous odour become by the air of the air inlet runner 1111.The utility model is most important to be set Meter, and the air cleaner with the market is maximum does not exist together, and is exactly the special Nanowire used in the utility model Dimension material does not simultaneously have Electrostatic Absorption function, but reaches filter effect by its hole densification, therefore the bidirectional fan 112 is anti- When blowing, you can the dirty of the surface of filter material 113 will be piled up in and outwards excluded, it is thus possible to effectively extend its service life, be not required to Change regularly, also remove the inconvenience frequently changed from.

The exhaust module 12 is then provided at the position of a gas outlet 22 of the confined space 2, and the air inlet 21 and the outlet Mouth 22 is arranged at intervals, and according to actual test, the interval between the air inlet 21 and the gas outlet 22 should cannot be less than 1.5 meters, keep away Exempt from the waste gas of discharge and be sucked back into filtering immediately, this is also the problem of general air cleaner occurs most frequently at present, and being exactly will be firm The air filtered sucks back filtering again, though its filter effect will not be influenceed, for the filtering efficiency in certain space Can not effectively it be lifted.When the utility model is implemented, the exhaust module 12 includes a hood 121 and a ventilating fan 122, the air draft The cladding of fan 122 forms a grate flow channel 1211 of closing in the hood 121, can be inhaled to be lifted wind-force in active set Power, the gas in the confined space 2 is discharged outside to.

The bidirectional fan 112 and the ventilating fan 122 is electrically connected in the control module 13, and the control module 13 includes One sensor 131 and a time switch 132, the sensor 131 supply to detect the concentration of the PM 2.5 inside the confined space 2, its During excessive concentration, the control module 13 can control that the bidirectional fan 112 is just blowing and the ventilating fan 122 operates simultaneously, will be extraneous empty Sucked after gas filtering in the confined space 2, and the air in the confined space 2 is discharged and carries out gas exchanges, directly When meeting standard to concentration, the control module 13 controls the ventilating fan 122 to shut down, and controls the bidirectional fan 112 simultaneously Blowback, the dirty exclusion that will be accumulated on the filter material 113.The time switch 132 can set the blowback of bidirectional fan 112 when Between, dirty exclusion that will be accumulated on the filter material.

Preferred embodiment of the present utility model is the foregoing is only, is not limited to the model of the utility model implementation Enclose, therefore the those of ordinary skill in the art, or be familiar with equivalent made by this technology or easily change person, The equivalent changes and modifications made under spirit and scope of the present utility model are not departed from, should all be covered by protection of the present utility model In the range of.
