It is related to the prevention cap.

In general, since the interior of the building has a closed structure, if the airtight condition lasts for a long time, indoor air is contaminated, adversely affecting the health of residents, and in severe cases, diseases such as respiratory diseases.

Indoor air in buildings causes pollution of indoor air due to the generation of dust, various foreign substances, carbon dioxide due to breathing, and the use of gas appliances for cooking due to residents' activities, thereby harming health when living for a long time.

Therefore, a cap provided with a mesh net or a plate is provided at the opening to prevent foreign matters such as rainwater and dust from flowing into the duct at the outer front end of the duct installed for indoor ventilation of the building.

As described above, the suction and exhaust holes covering the outside of the suction hole and the exhaust hole are formed on the outer wall of the building to prevent inflow of rainwater flowing down the wall of the building into the suction hole and the exhaust hole. Dragon cap is installed.

A through hole is formed in the cap so that air can be vented through the suction hole and the exhaust hole.

However, when the suction hole and the exhaust hole formed in the conventional cap are installed close to each other, there is a problem in that contaminated air in the room exhausted from the exhaust cap is sucked back into the suction cap to cause cross contamination.

In order to prevent or reduce such cross-contamination, it is necessary to install the suction holes and the exhaust holes with a certain distance apart. In reality, it is not easy to separate the suction holes and the exhaust holes by a considerable distance due to the structure of the building.

In addition, there is a problem in that the intake duct and the exhaust duct are complicatedly installed when spaced apart by a predetermined distance.

It is manufactured to be formed on opposite sides of the mutually opposite directions.

That is, the suction cap should have a first external ventilation hole formed on the left side, and the ventilation cap for exhausting should have a first external ventilation hole formed on the right side.

Therefore, the manufacturer has to manufacture the left and right types separately according to the location of the first external ventilation hole, so the productivity decreases and the manufacturing cost increases, and the worker has to purchase and install the left and right types separately. There is this.

In addition, all conventional caps have a ventilation hole formed on the bottom surface. Condensation occurs due to the temperature difference between the inside and outside of the building when installed on the wall surface of the building. There is a problem.

In addition, in the conventional cap, there is a problem that rainwater penetrates into the interior through the ventilation window and external air is introduced into the room.

In addition, the conventional cap has a problem that foreign substances including worms are introduced into the room through the ventilation window.

In addition, the conventional cap is difficult to assemble due to the fitting of the foreign substance strainer into the rear end of the body so that insects and the like do not flow.
