The bottom of the bottle insertion recess 19 and the bottom of the tank 5 are communicated by a pipe 20. A bottle cover 21 that covers the inserted bottle 18 is detachably attached to the bottle insertion recess 19.

The opening 18a of the bottle 18 is
8b, and in the bottle insertion concave portion 19,
A seal cutter 22 is provided for automatically breaking the seal member 18b of the bottle 18 inserted into the bottle insertion recess 19 with the opening 18a facing downward. The three seal cutters 22 are arranged in a line, and the bottle insertion recess 19 has a structure in which one to three bottles 18 can be inserted.

FIG. 4 shows the structure of the seal cutter 22 in an enlarged manner. The seal cutter 22 includes a ring body 22a, and the ring body 22a
Leg 22b for fixing to the bottom of the
It has a saw-tooth-shaped blade portion 22c protruding upward at the upper end side edge portion of a, and a push-up protrusion 22d. Ring body 22
The upper end side edge of “a” is formed in a direction obliquely intersecting the center line of the ring body 22a. Blade part 22c
Is formed except for the lowermost part of the entire periphery of the upper end side edge of the ring body 22a, and the push-up protrusion 22d is formed on the lowermost part in the inward direction of the ring body 22a. It is bent obliquely upward.

An airtight hermetically sealed space 23 is formed at the bottom of the main body case 1 and is shielded from the flow of air flowing through the main body case 1. An electronic circuit board 24 that controls various devices, for example, the fans 8 and 9, the ultrasonic unit 6, the ozone generator 7, and the like is housed in the closed space 23.

On one side of the bottom surface of the main body case 1, a pair of extendable and retractable feet 25 is provided.

This deodorizer is provided with a cigarette lighter plug (not shown) for taking power from a car battery and an AC adapter (not shown) for taking power from an indoor outlet. .

In such a configuration, a case will be described as an example in which the interior of a passenger car is deodorized using the deodorizer. In addition, the amount of hydrogen peroxide used is predetermined according to the size of the deodorizing space, and when deodorizing the interior of a passenger car having a small deodorizing space, one bottle of hydrogen peroxide is used. It is.

First, the deodorizer is placed on the floor of the passenger seat in the passenger car to be deodorized, and the expansion and contraction of the extensible feet 25 makes the deodorizer horizontal. Next, the bottle 18 containing the hydrogen peroxide solution is inserted into the bottle insertion concave portion 19, and the cigarette lighter plug is inserted into the cigarette lighter.

When the bottle 18 is inserted into the bottle insertion recess 19, the sealing member 18 b is attached to the blade 22 of the seal cutter 22.
c, and the hydrogen peroxide solution in the bottle 18 flows out of the port 18a. The hydrogen peroxide solution flowing out of the bottle 18 accumulates on the bottom surface of the bottle insertion concave portion 19 and further flows into the tank 5 through the pipe 20. Then, the liquid level between the bottle insertion concave portion 19 and the tank 5 is
At the point in time when it becomes equal to the lower edge of a, the outflow of the hydrogen peroxide solution from inside the bottle 18 is stopped. As described later, when the hydrogen peroxide solution in the tank 5 is atomized and reduced,
The reduced amount of hydrogen peroxide is supplied from the bottle 18.

The blade portion 22c of the seal cutter 22 is not formed on the entire periphery of the upper end side edge of the ring body 22a, but is partially formed on a part thereof.
When the seal member 18b is inserted into the bottle insertion concave portion 19 and the seal member 18b is broken by the blade portion 22c, the seal member 18b
Not separated from a. For this reason, the inconvenience that the seal member 18b separated from the port 18a is clogged in the pipe 20 does not occur. Further, the seal member 18b broken by the blade portion 22c is pushed up by the push-up protrusion 22d in the vicinity of a portion connected to the opening 18a. For this reason,
The once broken seal member 18b is prevented from returning to the position where the port 18a is closed due to the water pressure of the hydrogen peroxide solution in the bottle 18, and the outflow of the hydrogen peroxide solution from the port 18a of the bottle 18 is ensured. Will be

After the outflow of the hydrogen peroxide solution from the inside of the bottle 18 is stopped, the start button of the deodorizer is turned on, and the fans 8 and 9, the ozone generator 7 and the ultrasonic unit 6 are driven. Before turning on the start button, the upper lid covering the air outlet 3 is opened.

When the fans 8 and 9 are driven, air outside the main body case 1 is sucked into the main body case 1 from the suction port 2,
This air is branched into the first passage 13 and the second passage 14 and flows, then joins at the outlet 3 and blows out of the main body case 1. The air that has entered the guide body 10 from the first passage 13 rises straight inside the guide body 10.
On the other hand, the air blown out from the second passage 14 is
5 produces a swirling flow. For this reason, the air blown out from the outlet 3 is affected by the swirling flow of the air blown out from the second passage 14 and blows out while turning.

When the ultrasonic unit 6 is driven, the hydrogen peroxide solution in the tank 5 is atomized, and the atomized hydrogen peroxide solution is guided by air flowing through the first passage 13. The inside of the body 10 can be blown up.

When the ozone generator 7 is driven, a creeping discharge occurs on the outer peripheral surface of the glass tube 7a, and ozone is generated by the creeping discharge. Part of the generated ozone is carried from the lower end of the guide body 10 into the guide body 10 by the air flowing through the first passage 13, and is mixed with atomized hydrogen peroxide water by this hydrogen peroxide. Decomposes using water as a catalyst to generate hydroxyl radicals. Another part of the generated ozone is carried by the air flowing in the second passage 14 and mixed with the atomized hydrogen peroxide solution rising in the guide body 10, at which time the hydroxyl radical is generated again. I do.

Since the ozone and the hydroxyl radicals are blown out from the outlet 3 along the swirling flow, the ozone and the hydroxy radicals can quickly reach every corner of the vehicle, and the odor attached to the inner surface of the sheet or window glass. Can be deodorized.

In a case where the hydrogen peroxide solution atomized in the guide body 10 and ozone are mixed to generate hydroxy radicals, the density of the atomized hydrogen peroxide solution in the guide body 10 is reduced. Since it is high, the amount of generated hydroxyl radicals increases, and the deodorizing performance increases.

On the other hand, the ozone flowing through the second passage 14 is mixed with atomized hydrogen peroxide in the vicinity of the outlet 3 to regenerate the hydroxyl radical, so that the hydroxyl radical is generated in every corner of the vehicle. The time to reach is shorter. Therefore, even a hydroxyl radical having a short life can reach every corner of the vehicle before its life expires, and the deodorizing effect of the hydroxyl radical at every corner of the vehicle can be enhanced.

In the case of deodorizing the inside of the vehicle, by driving the air conditioner, ozone and hydroxyl radicals blown out from the air outlet 3 are sucked into the air conditioner, and the air conditioner piping and evaporator can be deodorized. .

When the deodorizing operation is started, the hydrogen peroxide solution is consumed with the lapse of time, and the bottle 18 is emptied. Then, the water levels of the hydrogen peroxide solution in the tank 5 and the bottle insertion concave portion 19 gradually decrease. When the float switch 17 detects that the level of the hydrogen peroxide solution in the tank 5 has fallen below a predetermined value, the driving of the ultrasonic unit 6, the ozone generator 7, and the fans 8, 9 is stopped. Deodorizing work in the vehicle is completed. After the deodorization work is completed, perform sufficient ventilation and remove the deodorizer from the vehicle.

The float switch 16 detects a case where a predetermined amount or more of hydrogen peroxide water flows into the tank 5 because the deodorizer is tilted too much, and a warning buzzer sounds based on this detection. If this warning buzzer sounds,
Tilt the deodorizer so that the bottle insertion recess 19 is on the lower side,
The level of the hydrogen peroxide solution in the tank 5 is lowered to a predetermined position by discarding the hydrogen peroxide solution in the bottle insertion concave portion 19.

In the main body case 1, the main body case 1
Since the fans 8 and 9 are arranged on the upstream side of the air flowing through the inside, and the ozone generator 7 and the ultrasonic unit 6 are arranged on the downstream side, ozone and atomized hydrogen peroxide water are supplied to the fan 8. , 9 is prevented from being deteriorated by oxidation of the fans 8, 9 without being touched. Further, since the filter 4 is attached to the suction port 2, even if the ozone or the hydrogen peroxide solution discharged into the vehicle is sucked into the main body case 1 from the suction port 2, the ozone or the hydrogen peroxide solution is removed. It is removed by the filter 4.
Therefore, it is possible to more reliably prevent the fans 8 and 9 from being deteriorated by touching ozone or hydrogen peroxide solution.

Further, since the electronic circuit board 24 is housed in the closed space 23 and the closed space 23 is shielded from the air flowing through the main body case 1, the electronic circuit board 24 is made of ozone or atomized hydrogen peroxide. Deterioration due to contact with water can be reliably prevented.

Since the air flowing around the ozone generator 7 in the main body case 1 flows along the longitudinal direction of the ozone generator 7, the air flowing in the main body case 1 is in contact with the ozone generator 7. , The generation of ozone is promoted and the generation of hydroxy radical is also promoted, and the deodorizing effect is enhanced. In addition, since the installation space for the ozone generator 7 is reduced, the size of the deodorizer can be reduced.

Next, the case where the deodorizer is used to deodorize the interior of a hotel room or the inside of a karaoke box will be described. The basic operation and operation are the same as those for deodorizing the inside of the vehicle. However, because the space for deodorization is large,
The bottle 18 to be inserted into the bottle insertion recess 19 accordingly.
Is increased to two or three. As a result, deodorization can be performed using an optimal amount of hydrogen peroxide according to the deodorizing space, and waste due to excessive use of the hydrogen peroxide can be eliminated. In addition, if the output of the ultrasonic unit 6 is kept constant, the time required for the deodorization work is proportional to the number of bottles 18 used, so that the time management of the deodorization work can be easily performed.
