For example, small porous cylinders and porous cylinders may be alternately provided in a double membrane with a partition plate interposed therebetween. Furthermore, various embodiments such as changing the vertical positions of the small porous cylinder and the porous cylinder can be adopted.

<Effects of the Invention> According to the present invention, the deodorizing liquid tank faces the tip of the intake pipe connected to the base of the connecting pipe connecting the vacuum exhaust pipe and extending downward into the casing. In a deodorizer for a vacuum vehicle in which a shielding plate and a partition plate are installed in the upper part of the tank and an exhaust hood is connected to the upper part of the casing, a truncated porous cylinder is connected to the tip of the intake pipe. The bad odor that has flowed into the intake pipe is injected into the deodorizing liquid in the deodorizing liquid tank through the plurality of ejection holes of the truncated porous cylinder, and is stirred in the form of bubbles, resulting in an extremely efficient deodorizing effect. Excellent effects can be achieved.

Further, a plurality of small porous cylinders are interposed between the shielding plate on the upper part of the deodorizing liquid tank and one partition plate provided in the middle of the intake pipe and having a blow-off hole near the intake pipe. A porous cylindrical body is interposed between one partition plate and the other partition plate, which is provided at the upper part of the intake pipe and has a blowout hole near the casing, so as to surround the intake pipe. , the odorless air containing moisture deodorized by the deodorizing liquid is the small porous cylinder;

The deodorizing liquid can be discharged to the outside air through the 11-air hood, and the separated water is returned to the deodorizing liquid tank, which has the advantage of significantly reducing the amount of deodorant liquid consumed.

Furthermore, the fact that the check valve provided in a part of the connecting pipe is able to come into contact with and separate from the rod connected to the internal pressure detection cable of the vacuum pipe via a lever is particularly noteworthy. , When the pressure inside the vacuum tank temporarily increases rapidly during the work of removing floor seats (even if the air pressure in the vacuum tank increases rapidly (2), excessive exhaust gas does not flow into the deodorizer, and the outside air is temporarily released from the upper part of the connecting pipe. It is possible to control the amount of exhaust gas that flows into and into the deodorizer, which allows stable deodorization work at all times, and prevents excessive load from being suddenly applied to the deodorizer, which may cause it to malfunction. There are some benefits that are not available.
