Detailed Description
As shown in fig. 1 and 3, the air purifier comprises a purifier main body 1, an air purification assembly is arranged in the purifier main body 1, one end of the purifier main body 1 is a fresh air output end 2, the other end of the purifier main body is an air input end 3, a filter screen 7 is arranged on the outer side surface of the air input end 3, and an air inlet cavity 4 on the purifier main body 1 is sealed through the filter screen 7;
a movable mounting closing plate 5 in the chamber of admitting air 4, closing plate 5 cuts off chamber of admitting air 4 for two confined cavities, the fixed elastic airbag 6 that sets up in relative filter screen 7 one side on closing plate 5, be provided with inlet channel 9 on the 4 internal faces of chamber of admitting air, inlet channel 9 switches on external and chamber of admitting air 4, when clarifier host computer 1 is out of work, closing plate 5 seals inlet channel 9 to block external and chamber of admitting air, elastic airbag lateral surface and filter screen face contact extrusion.
Wherein, the elastic air bag 6 is made of elastic rubber material, a gas storage cavity (not shown) is arranged in the elastic air bag 6, the elastic air bag 6 is pressed against the inner side surface of the filter screen 7 through more than one connecting piece 8, the more than one connecting pieces 8 are all elastic belts, one end of each connecting piece is fixedly connected with the filter screen, the other end of each connecting piece is fixedly connected with the sealing plate 5, when the purifier main machine 1 works, the elastic belts are stretched, the connecting pieces 8 are stretched, the elastic air bag 6 can be separated from the filter screen, as shown in figure 2, the air inlet channel 9 is conducted, external air can be sucked through the air inlet channel 9, when the purifier main machine 1 works, the air inlet end sucks air, the whole air inlet cavity is in a negative pressure state when the purifier main machine works, the negative pressure enables the sealing plates to move towards the side of the air inlet end, and further enables the elastic air bag to be far away from the filter screen 7, and the air inlet channel is conducted, the inner diameter of the air inlet channel cannot be set to be too large, otherwise the negative pressure is not enough, so that the sealing plate cannot generate negative pressure displacement, and therefore continuous air suction needs to be realized while the negative pressure suction force is ensured.
As shown in fig. 4, after the elastic airbag 6 contacts and compresses the filter screen 7, the elastic airbag 6 is partially buckled in the mesh 71 of the filter screen, and the convex part 61 which bulges outwards is formed on the elastic airbag 6, at this time, the purifier main body 1 is in a non-operating state, at this time, under the action of the elastic belt, the elastic airbag 6 is compressed with the filter screen 7, and after the elastic airbag 6 is compressed, the elastic airbag 6 is partially buckled in the mesh, as shown in fig. 5, at this time, the elastic airbag 6 is used for ejecting out dust in the mesh 71, a user can use the cleaning cloth to erase the outer side surface of the filter screen 7, and the user does not worry about pushing the dust into the mesh, so that the cleaning is more convenient.
As shown in fig. 2, air inlet channel 9 is "C" font, and it is close to filter screen one end and is the air inlet 91, is close to air input end one side and is the gas outlet 92, and fine filter screen of air inlet 91 one side installation, when clarifier host computer 1 is out of work, and the closing plate 5 is located the position of air inlet 91 and seals air inlet 91, and the inside and outside space blocks this moment, also does not have the circulation of air yet, prevents the entering of outside steam, increases the life of clarifier host computer 1.
In this embodiment, the outer wall surface of the sealing plate 5 is provided with an outer sealing ring to increase the sealing performance with the air inlet cavity, the bottom of the purifier main body 1 is provided with a fixing support 11, and the fixing support 11 is used for supporting the purifier main body 1.
Wherein, one side of the filter screen on the elastic air bag 6 is provided with more than one small air injection holes (not shown), when a convex part is formed on the elastic air bag 6, the air in the elastic air bag 6 is sprayed out from the small air injection holes and impacts on the outer side surface of the filter screen 7, the elastic air bag 6 is made of elastic rubber material with deformation recovery capability, when the purifier host 1 is closed, the elastic air bag 6 is tightly pressed with the filter screen through an elastic belt, in the initial compression stage, the air in the elastic air bag can be sprayed out from the small air injection holes, dust on the outer side surface of the filter screen 7 can be blown off to a certain degree, until the amount of the air in the elastic air bag 6 is insufficient, the convex part of the elastic air bag 6 disappears, the elastic air bag is not buckled in the mesh, after the purifier host works, the sealing plate displaces to drive the elastic air bag to displace, and after the elastic air bag is not contacted with the filter screen, the elastic air bag 6 slowly sucks in external air through the small air injection holes to recover deformation, the squeezing is carried out again after the machine is shut down, and the process is circulated, so that the cleaning can be realized once only by using the machine every time, and the dust is prevented from being accumulated.
The invention has the beneficial effects that: the invention can realize automatic conduction of meshes and automatic cleaning of the filter screen by using the air bag, and realize blocking of the inner space and the outer space by using the sealing plate, and can effectively block external moisture and dust from entering the inside of the purifier host when the purifier host is not used, thereby greatly prolonging the service life of the purifier host.
The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the inventive work should be included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
