• FIG. 2 and 3 are isometric side views in both different direction to make easy understanding of the outside feature of the sub assembly ( 20 ) for the device to protect offensive odor and vermin which is used to this patented device to protect offensive odor and vermin from the sewage.
• the sub assembly ( 20 ) for the device to protect offensive odor and vermin which is used to this patented device to protect offensive odor and vermin from the sewage is equipped with the inlet opening hole ( 40 ) at the top side and the body section ( 44 ) where running water coming from the inlet opening hole ( 40 ) at the top side go through is composed with the round shape and on the one side of the bottom is composed with the sloped outlet ( 42 ) and on the out side of the aforementioned outlet opening hole ( 42 ), there is a hinge bracket ( 49 ) on the top side of the body section ( 44 ) and hinge ( 48 ) is inserted in the hinge bracket ( 49 ) so that the open and close door plate ( 49 ) can be opened automatically by the weight of the inlet sewage and can be closed automatically by the plate spring after discharging the sewage.
• these sub assembly ( 20 ) to protect offensive odor and vermin from the sewage are composed with the rectangular shape for the upper assembling parts but the other inner rim of the body section ( 44 ) are composed with unique feature of round shape to make opening outlet of the running water smoothly and protect accumulation or suspension of the foreign material and sludge coming in with the running water in side of the device.
• FIG. 4 is a sectional view 'A-A' and detail view of the sub assembly ( 20 ) to protect offensive odor and vermin from the sewage, and in this drawing as shown, there is an elastic device ( 50 ) which control the opening and closing of the open and close door plate ( 46 ) located on the top of the outlet opening hole ( 42 ) in which the aforementioned open and close door plate ( 46 ) is installed on it.
• this elastic device ( 50 ) is composed of a plate spring and assembled on to the body section ( 44 ) and make the opening and closing of the open and close door plate ( 46 ).
• this elastic device ( 50 ) can be optionally made of the coil spring which will be wound to the hinge ( 48 ) and any kinds of elastic device which can surely make opening and closing of the open and close door plate ( 46 ) will satisfy these function.
• FIG. 5 shows the assembled condition of the multiple devices of the sub assembly
• protection device for the offensive odor and vermin(l ⁇ ) that uses multiple devices of the sub assembly to become a united body and the number of the sub assembly to be used to be the completed protection device for the offensive odor and vermin(20) depending on the size of the drain and on the outer rim of protection device for the offensive odor and vermin( 10 ), it is a supporting plate( 60 ) to be hanged to the man hole of the sewage.
• the mounting hole( 62 ) of supporting plate( 60 ) is first inserted into the gap( 25 ) and in case the middle protruded leaf( 24 ) is located on the most outer side, on the top side of this middle protruded leaf, the one side of the supporting plate where mounting hole is located will be laid down to the middle protruded leaf and is fixed with screw so as to be parallel with the surface of protection device for the offensive odor and vermin.

• the assembled condition and detail view of the assembled condition is shown in FIG. 7.
• the adjustable channel( 70 ) mentioned above can be inserted between sub assembly ( 20 )to protect offensive odor and vermin from the sewage as explained above but it can also be used on the most outer side of the united sub assembly ( 20 ) to protect offensive odor and vermin from the sewage by attaching supporting plate( 60 ) to the out side of it.
• the number of the sub assembly to protect offensive odor and vermin from the sewage of the patented protection device for the offensive odor and vermin( 10 ) can be decided depending on the size of the sewage man hole, it can be applied to the various sizes of the sewage man hole.
• the protection device for the offensive odor and vermin( 10 ) can be composed of multiple of sub assembly ( 20 ) to protect offensive odor and vermin from the sewage by tight fit each other using the gap ( 25 ) and upper and bottom protruded leaf ( 22 )( 26 ), it can be assembled easily and give the convenience of the installation with out the need of the special tool.
• the sub assembly ( 20 )device to protect offensive odor and vermin from the sewage that has the supporting plate( 60 ) assembled can be hanged on the inner part of the sewage man hole.
• open and close door plate( 46 ) When weight has been reduced on open and close door plate( 46 ) after the running water has been discharged, open and close door plate( 46 ) will close the outlet opening hole ( 42 ) promptly due to the elasticity of the elastic device( 50 ) and do not let any offensive odor or vermin created inside the sewage be emitted to the outside.
• the inner rim of the sub assembly device to protect offensive odor and vermin from the sewage is a round shape, even if some foreign materials come in with the running water, it will not let suspend or accumulate on it effectively compare with the former square shaped device.
• this patented sub assembly ( 20 ) to protect offensive odor and vermin from the sewage is assembled and installed in standardized size, there will be a differences in size between the most outer rim of protection device for the offensive odor and vermin and the size of the man hole cover for the sewage.
• adjustable supporting channel( 70 ) can be equipped additionally to adjust the gap between sub assembly to protect offensive odor and vermin from the sewage.
• this protection device for the offensive odor and vermin can be used just by simply assembling multiple sub assembly devices to prevent offensive odor and vermin, the installing is simple allowing reduction of cost and increase the efficiency. And should there be a small difference in size between the assembled sub-assembly devices to prevent offensive odor and vermin and the man hole, width adjusting device can be inserted between the most outer rim of the sub- assembly devices to protect offensive odor and vermin and the supporting channel ( 70 ), the gap will disappear and the odor and vermin can be effectively prevented from coming out from the sewage. And since the inner rim of the body section is round shaped, even if some foreign materials coming in with the running water, it won't remain inside nor disturb the discharge of the running water thus it is much more effective than the former square-shaped body section.
