BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aroma spraying device for supplying aroma to a hall, an atrium, or a conference room by being installed in an air conditioning apparatus installed in a building.

In recent years, the interest in fragrance has increased, and the movement which actively introduces the component of the fragrance which promotes work efficiency and the fragrance component suitable at the time of rest is thriving.

The invention described in Japanese Unexamined Patent Application Publication No. 2-112767 has already been disclosed as an aroma device attached to an automatic air conditioner.

In this design, as shown in FIG. 1, the spray device 2 is attached to the vertical wall surface of the air conditioning tube 1, and the compressor 3 supplies compressed air to the spray device 2 to mist the fragrance components. As a result, the building is supplied with aroma.

Reference numeral 4 is a control panel for controlling the drive of the compressor 3, and 5 is a switch for driving and stopping the device.

Then, a mist-like fragrance liquid is sprayed into the room in accordance with the conditions such as a timer set by the switch 5.

More specifically, the spray apparatus 2 will be attached directly to the vertical wall surface of the air conditioning tube 1 as shown in FIG. 2, but the air blowing hole 6a and A fragrance liquid ejection hole 6b is provided in the center, and the fragrance liquid stored in the fragrance liquid tank 7 is sucked into the spray tube 8 and misted by the jet of compressed air discharged from the compressor 3.

Reference numeral 9 denotes a communication tube, and communicates with the outside air to make the internal pressure of the aromatic liquid tank 7 equal to atmospheric pressure.

By the way, in the above-mentioned conventional example, the spray apparatus 2 is attached to the direct air-conditioning pipe 1.

In addition, the aroma liquid tank 7 must also be attached near the outside of the air-conditioning pipe 1.

However, the fragrance liquid is a consumable and must be replaced with a new tank when the tank is empty.

Normally, however, the air conditioning tube 1 is provided on the ceiling, and the tank cannot be replaced easily.

Therefore, there is an inconvenience that a worker must be relied on to replace the tank.

On the other hand, if only the fragrance liquid tank 7 is provided in another position, there exists a problem that the siphon principle of a spray nozzle cannot fully be utilized in the conventional system.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems, and provides a fragrance feeding device capable of generating a stable mist in addition to a structure that anyone can easily exchange when the fragrance tank becomes empty. The purpose.

In the present invention, in order to achieve the above object, a spray device attached to the air conditioning tube, and sprayed by misting the fragrance liquid filled in the sealed tank, and the compressed air supplied to the spray device and sucked into the suction pipe An aroma spray device composed of a compressor is used to mist the liquid.

In addition, the aroma liquid tank is installed at a relatively low position, and the compressor supplies compressed air to the aroma liquid tank through the regulator, and connects the aroma liquid tank to the level device installed near the spray apparatus. In accordance with the above, the fragrance liquid is pushed up, and the above-mentioned level device employs a device that provides a suction pipe to the spray device.

In addition, as a level device, a device was used to block and release the aroma liquid piping port by a float that moves up and down in association with the aroma liquid.

In the above apparatus, the compressor supplies a jet to the spray apparatus to spray mist, pressurizes the liquid level of the aromatic liquid tank, and pushes the aromatic liquid to the level apparatus along the pipe. To act.

The leveling device functions to stably supply the fragrance liquid to the spraying device, and to shorten the suction pipe to make the compressor pressure low.

The float of the leveler also functions as a valve for adjusting the supply of fragrance liquid to the leveler.

Hereinafter, one embodiment of the present invention will be described with reference to the accompanying drawings.

Figure 3 shows the piping of the spray apparatus employed in the present invention, reference numeral 1 denotes a compressor, 2 denotes a spray nozzle, 3 denotes an aroma liquid tank, 4 denotes a regulator, and 5 denotes a It is a level device.

6 is an air pipe, 6a is a main pipe in the compressor 1, 6b is a branch pipe to the aroma liquid tank, and 6c is a branch pipe to the spray nozzle 2. As shown in FIG.

Next, reference numeral 7 denotes a liquid pipe, 7a denotes a pipe for supplying the aromatic liquid from the aromatic liquid tank 3 to the leveling device 5, and 7b denotes a spray nozzle 2 in the leveling device 5. ) Is a suction tube for

At this time, the aromatic liquid tank 3 is a sealed tank, and the compressed air in the compressor 1 is pressure-controlled by the regulator 4 and supplied to the open chamber 3a of the aromatic liquid tank 3.

Then, the air pressure set by the regulator 4 acts on the aromatic liquid filled in the aromatic liquid tank 3, and the aromatic liquid pushes up the pipe 7a and is supplied to the level apparatus 5. As shown in FIG.

Since the compressed air of the compressor 1 is also supplied to the spray nozzle 2 via the branch pipe 6c, the compressed air is jetted at the nozzle end, and the negative pressure (pressure) causes the level device ( The fragrance of 5) is sucked up and misted and sprayed.

In addition, although abbreviate | omitted in drawing, the drive of the compressor 1 is controlled by a switch like a conventional thing, and it goes without saying that the time control is performed by a timer.

In the configuration of FIG. 3, since the fragrance liquid tank 3 can be installed at a distance from the spray nozzle 2, for example, if only the fragrance liquid tank 3 is installed indoors or in a place where the hand touches, the remaining amount of the fragrance liquid in the tank is also increased. It is easy to check, and even if it is empty, the exchange is simple.

By the way, the pressure adjustment by the regulator 4 is determined in consideration of the level difference between the liquid level of the aroma liquid tank 3 and the discharge port of the pipe 7a with respect to the level device 5, but if the pressure is too high, the level device 5 When the aromatic liquid is ejected with respect to the liquid, the liquid level of the aromatic liquid tank 3 is lowered, so that the aromatic liquid cannot be supplied sufficiently to the leveling device 5.

In view of these, the set pressure of the regulator 4 is adjusted.

Next, the details of the leveling apparatus 5 are shown in FIG.

Reference numeral 8 denotes an apparatus body, 9 a float valve 10 a float, and 11 a directional liquid inlet.

The float 10 is controlled by the lifting guide 12 to the left and right movement.

Reference numeral 13 denotes a valve sheet formed on the inlet end surface, and the float 10 pushes up the float valve 9 as the liquid level rises, so that the side surface of the float valve 9 is the valve sheet 13. Closing the entrance by seating on

Since the fragrance liquid flowing in from the inlet is pressurized by the compressor 1 and the regulator 4, the buoyancy of the float 10 needs to be larger than the inflow pressure of the fragrance liquid.

With such a configuration, when the aroma liquid is sucked up from the suction pipe 7b and the liquid level is lowered, the float valve 9 is released from the valve seat 13, and the main body 8 is opened through the aroma liquid inlet 11 at the inlet. Flows into.

When the liquid level rises due to this inflow, the valve is closed again.

Therefore, since there is always an aroma liquid in the level device 5, and the suction of the liquid by the air jet of the spray nozzle 2 can also suppress the height of the suction pipe, it is sufficient to supply low pressurized air. Do.

Since the present invention adopts the above-described configuration, the fragrance liquid misted in the spray apparatus can be supplied to the room.

Moreover, since the fragrance liquid tank is provided in a low position, even if it replaces a tank because there is no fragrance liquid, it can be set as the structure which can be replaced easily.

Furthermore, since a level device is installed between the aroma liquid tank and the spray device, and the aroma liquid accumulated in this level device is sucked up by the suction pipe, the compressed air supplied from the compressor is also good at low pressure, safe and noise. Can be suppressed.
