Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples, but the embodiments of the present invention are not limited thereto.
As shown in fig. 1 to 3, the waterproof and dustproof vent plug of this embodiment includes a plug 200 and a plug 100, the cross-sectional area of the plug 200 is larger than the cross-sectional area of the plug 100, a rubber pad may be disposed on the bottom of the plug 200 and a portion larger than the cross-sectional area of the plug 100 to prevent gas with contaminants from flowing from gaps to the inside to cause contamination, the plug 200 includes a plate 204 having a sunken recess 203 disposed in a center of one end thereof and a cover plate 201 covering the recess and disposed on the top of the plate 204, one end of the cover plate 201 is disposed with an upper floating protrusion 2014, the recess is conveniently inserted with an adsorption screen 202 to remove dust from air flowing into the plug 100 through the hole 205, the plate 204 is provided with a hole 205 through the center thereof, the screen 202 is horizontally inserted in the middle of the plate 204 corresponding to the recess 203, the cover plate 201 includes a cover 2013 vertically penetrating through the plate surface and a slide 2011 embedded in the cover plate to control opening and closing of the cover 2013, the cap 2013 is a through opening through which air flows into the container from the outside, the sliding plate 2011 is connected with the cover plate 201 in a sliding mode and used for controlling the size of the cap 2013, a raised handle 2012 is arranged on the sliding plate 2011, and the handle 2012 is used for controlling the sliding plate 2011 to slide up and down.
The plug body 100 is connected with the other end face of the plate 204, the plug body 100 is a barrel body with a central hole, the central hole comprises a first through hole 101 close to the plate and a second through hole 102 coaxially communicated with the first through hole 101, the first through hole 101 is arranged right below a hole 205 on the plate 204, a water-absorbing sponge is attached to the inner wall of the first through hole 101 and used for adsorbing formed condensed water, and a breathable film 103 is arranged between the first through hole 101 and the second through hole 102.
In this embodiment, the stopper body 100 of the venting plug is installed on a hole formed in a container wall, after the stopper body is installed, the handle 2012 is pushed upwards, the sliding plate 2011 connected with the handle 2012 moves upwards correspondingly, the cover 2013 shielded by the sliding plate 2011 is also opened, so air enters the cover plate 201 from the cover 2013, the air firstly passes through the adsorption screen 202 and then enters the first through hole 101 and the second through hole 102 of the stopper body 100 through the hole 205 on the plate 204, when the air passes through the adsorption screen 202, the adsorption screen 202 adsorbs dust contained in the air, the remaining fresh air enters the first through hole 101 through the hole 205 and then enters the second through hole 102 through the vent film 103 between the first through hole 101 and the second through hole 102, so as to achieve the venting effect on the container, and after a long time of venting, condensed water is formed at an air inlet and flows downwards, because the water absorption sponge is attached to the inner wall of the first through hole 101, the flowing condensed water can be absorbed, and the phenomenon that the condensed water drops on the breathable film to block the breathable film is avoided.
Although the present invention has been described with reference to the above preferred embodiments, it is not intended to limit the scope of the present invention, and those skilled in the art can make various changes and modifications with respect to the above preferred embodiments without departing from the spirit and scope of the present invention.
