Skill realization Elements of wave filter housing

Skill Completion elements:

The purpose of the utility model is to provide a good sealing performance and can be useful for insect protection.Filter housing

The above skill of the utility model is accomplished by the following skill scheme: a filter housing comprising a bottom box and an upper cover capable of working with the bottom box, the outer wall of the bottom box is provided with a circle extending to the top of the bottom box level, and the top bulge is also provided with a circle extending to the second bulge at the bottom of the base box, The side wall of the bottom box, the top bulge and the second bulge are stepped, and the upper distance of the top protrusion is set with a plurality of third bulges with the second bulge level, and the upper cover corresponds to the top ladder, and the upper cover is also provided with a third groove corresponding to the third bulge. The third groove and the third bulge are respectively provided with a top magnet and a second magnet that can cooperate with each other, and the top bulge avoids the position of the third bulge and is provided with an air bag with ammonia stored internally.

After selecting the above skill scheme, set the top bulge and the second bulge on the outside wall of the bottom box to make the side wall of the bottom box step, and set the top ladder on the inner wall of the upper cover to cooperate with the top bulge set on the bottom box; When used, the upper cover is pressed downward, which is the second protruding surface level after the top ladder and the third bulge and the third groove cooperate with each other can play the role of limiting position, set in the third Groove and the third bulge on the magnetic opposite of the top magnet and the second magnet can cooperate with each other, under the action of magnetic adsorption to prevent the upper cover and bottom box off; When a cockroach or other worm passes through a gap after the upper and bottom boxes are buckled, the airbag is punctured, because the two ends of the airbag are glued to the filter upper cover and the Filter bottom box respectively, the insect can not pass between the upper cover and the bottom box, if the air bag must be punctured, set in the air bag to release the ammonia, ammonia has a fierce smell, It can play the effect of deworming, followed by the expansion of ammonia to wrap the insect, the insect and the oxygen in the air isolated, so that insect asphyxiation died; in other cases, the surrounding operators can also smell the smell of ammonia to check for manual finishing.

As preferably, there are several sub-cavities for storing ammonia in the inner air bag.

After selecting the above skill scheme, the air bag is separated into a multi-ovary cavity, and the ammonia gas is stored evenly in the sub-cavity, which can prevent all ammonia from being released when a worm invades, and the taste punches the nose. Other such settings do not have to be invalidated after the insect invasion once, and the airbag waste material needs to be replaced again.

As preferably, there are several second through holes on the upper cover, and a waterproof and breathable film is arranged on the second through hole.

After selecting the above skill scheme, the relative molecular weight of ammonia is less than the relative molecular weight of air, so the release of ammonia gas will occur upward movement trend; ammonia gas can be dispersed outward from the second through hole; second, during the operation, the heat of the internal electronic components can also be dispersed from the second through hole, Prevent heat accumulation in the filter housing, so that the internal electronic components after heating the resistance to increase, affecting the normal operation.
