Description

[Detailed explanation of the idea] The present invention relates to an improvement of a deodorizing device.

For example, in a vacuum car as shown in Figure 1,
A deodorizing device is installed to purify the odor inhaled into the tank a and then release it into the atmosphere.

As described above, the present invention mainly relates to a deodorizing device for purifying odors.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings. FIGS. 2 to 9 show the first embodiment, and 1 is a main body of an outer casing that is approximately cylindrical with a bottom; A canopy 2 is detachably attached to the main body 1, and a deodorizing chamber 3 having a substantially cylindrical shape is formed inside.

4 is an air supply hole that opens at the upper part of the circumferential surface of the deodorizing chamber 3;
It passes through an air supply pipe 5 that integrally projects outward from the main body 1.

6 is an exhaust hole that opens at the lower part of the circumferential surface of the deodorizing chamber 3;
An exhaust pipe 8 extending substantially vertically extends through a connecting portion 7 that integrally projects outward from the main body 1 to the upper end thereof.

Further, as shown in FIG. 6, the passage 9 near the opening of the air supply hole 4 is connected to a plane (a virtual plane
), and the passage 10 near the opening of the exhaust hole 6 includes another plane (virtual plane B) in contact with the circumferential surface of the deodorizing chamber 3, as shown in FIG. The directions of formation of both passages 9 and 10 are opposite in the circumferential direction of the circular bottom surface 3a of the deodorizing chamber 3 (in FIG. 4, the former 9 is counterclockwise toward the opening, and the latter 10 is arranged in the same clockwise direction).

Reference numeral 11 denotes an ozone light emitting lamp attached to the lower surface of the canopy 2, and a power circuit is wired from a connection chamber 12 on the canopy 2 to the outside.

13 is a surplus odor recovery hole bored in the canopy 2;
14 is a drain hole, and 15 is a fixed fin.

The deodorizing device having the above configuration is installed in a vacuum car, for example as shown in FIG. At the same time as the pump C is started, the ozone light emitting lamp 11 is turned on.

Of course, it is also possible to use the same switch circuit.

The odor sent from the air supply hole 4 into the deodorizing chamber 3 is sent from above the deodorizing chamber 3 in the horizontal rotation direction from the formation position and direction of the passage 9 near the opening of the air supply hole 4, and the odor is sent into the deodorizing chamber 3 from above.
descending while rotating inside (counterclockwise direction in Figure 6)
During that time, it is irradiated by the ozone luminous lamp 11 and purified.
It passes through an exhaust hole 6 that opens below the circumferential surface of the deodorizing chamber 3 and is discharged into the atmosphere from the upper end of an exhaust pipe 8.

In addition, trimethylamine, methyl mercaptan, etc., which are present in the odor whose main component is methane gas, etc. and have a relatively small specific gravity, are difficult to descend in the deodorizing chamber 3, so they are refluxed into the tank a from the surplus odor recovery hole 13. Ru.

Further, the moisture contained in the odor is returned to the tank a through the drain hole 14.

Therefore, according to the above-mentioned deodorizing device, the odor sent into the deodorizing chamber 3 descends while rotating in a spiral shape, and the ozone light emitting lamp 11 continues to be irradiated with the odor all the while.
The irradiation time can be extended and an excellent purification effect can be obtained.

In this case, if the air supply hole 4 and the exhaust hole 6 are opened as vertically as possible in the deodorizing chamber 3, the rotation and descent of the odor inside the deodorizing chamber 3 becomes smooth.

Further, the fixed fins 15 are provided in the deodorizing chamber 3 so as to be the center of the rotational flow in order to ensure rotational flow of odor within the deodorizing chamber 3 for the purpose of enhancing this purification effect.

That is, the fixed fin 15 has eight fins 17 arranged on the outer periphery of a substantially cylindrical center body 16, and is erected in the center of the deodorizing chamber 3 with legs protruding from the bottom.

Thus, the odor sent through the air supply hole 4 becomes less likely to generate turbulence, and descends while rotating around the fixed fins 15.

As explained above, the deodorizing device of the present invention has an air supply hole and an exhaust hole formed in the outer casing having a deodorizing chamber having a substantially cylindrical shape, and the air supply hole is opened at the upper part of the circumferential surface of the deodorization chamber, and the exhaust hole is formed in the outer casing. is opened at the lower part of the circumferential surface, and the passages near the openings of the air supply hole and the exhaust hole are arranged in positions and directions that include the same or different planes (virtual planes) touching the circumferential surface of the deodorizing chamber, and both passages The direction of the deodorizing chamber is reversed in the circumferential direction of the circular bottom surface of the deodorizing chamber, a fixed fin is installed in the deodorizing chamber as a center of rotational flow of odor, and a required number of external power circuits are wired inside the deodorizing chamber. In particular, by specifying the formation position of the air supply hole and exhaust hole, the formation direction of the passage near the openings of both, and the installation of fixed fins, a rotational flow of odor is generated in the deodorization chamber, and a relatively low odor is generated. It is possible to continue irradiating ozone over a long period of time and cause a chemical reaction to occur.
It not only allows sufficiently purified odor to be released into the atmosphere, but also has an excellent sterilizing effect, which has great practical effects.
