In this case, dust is removed from the air taken in through the grill cover 3 by the air filter 6, and then aromatic components and insecticidal components are added when the air passes through the grill unit 5. This type of air intake is shown in Figure 4 (a).
, (b), this is performed by a fan 20 provided in the center of the main body I. The air that has passed through the grill unit 5 is then passed through the fan 20.
The liquid is sent to a dome-shaped mix chamber 21, where it is blown upward and discharged to the outside. In this case, the fan 20 is attached to the lower end opening of the mix chamber 21 via a vibration isolating rubber 24. Further, an inverted pyramid-shaped head frame 22 is placed close to the upper opening of the mix chamber 2I, thereby narrowing the air outlet and increasing the flow rate.

Components corresponding to those in FIG. 4 are given the same reference numerals.

As shown in FIG. 5, the above-mentioned spray controller 31 is made up of components surrounded by dashed lines. Here, SPM is a spray motor whose rotation/stop is controlled by a motor controller MC, and its driving force is generated by a piston clutch Pc, as shown by a two-dot chain line in the figure.
t, PC2° is transmitted to PO2. The piston clutch PC1 transmits the driving force of the spray motor SPM to the ejection part SPI, and its attachment and detachment are controlled by the clutch controller CC1. The ejection part SPI is composed of a cylinder, a piston, a link mechanism, etc., and includes a piston clutch Pc.
When the driving force is transmitted from t, the piston strokes. That is, the action of pulling the piston to suck up the liquid from inside the bottle Bl, and pushing the piston to push out the liquid, using the reed vibe RPl and the nozzle adjuster NAdl.
An operation is performed in which the liquid is ejected from the nozzle tip T1 into the mix chamber 21 through the nozzle tip T1. The lead pipe RPl is a guide pipe for the ejected liquid, and the nozzle adjuster NAdl adjusts the distance between the tip of the reed vibe RPI and the nozzle tip TI to adjust the spread angle of the ejected mist. This nozzle adjuster NAdi can be adjusted by the manual adjustment part 1 (Cl), and the spread angle of the ejected mist is usually adjusted in advance depending on the installation location.

Further, the position of the piston of the spouting part SPI is detected by a sensor BSl, and a detection signal from this sensor BSI is supplied to the control part 40. Further, the clutch controller CC1 and motor controller MC described above operate based on control signals supplied from the control section 40. In this case, one of the clutch controllers CCl-CC5 is selected to be in the engaged state, and the others are in the disengaged state.

The above is the configuration of the system for spouting the liquid in the bottle Bl among the components of the spray controller 31.

Here, the suffix 2゜3 added to the symbol attached to the component indicates each bottle B2. It constitutes a system for ejecting the liquid in I33, and its function and configuration of each part are exactly the same as the system for bottle Bl.

Next, reference numeral 40 shown in FIG. 1 is a control section for controlling various parts of the apparatus, and as shown in the figure, it is attached to the center of the front surface of the main body l. In the figure, reference numeral 41 denotes a button-type touch switch, which is operated for manual control. 42 is a receive sensor, and when controlling by remote control, a predetermined transmitter 50 (see Fig. 5) is used.
It is the party who receives the transmitted signal from the party. In this case, a radio wave, an ultrasonic wave, an infrared ray, or the like is used as the transmission signal, and a sensor corresponding to the propagation medium is used as the receive sensor. 43 and 44 are small speakers for generating alarms and messages, such as piezoelectric speakers.

The electrical configuration of the control section 40 is as shown in FIG. In this figure, 4G is a control circuit comprised of a CPU (Central Processing Unit), RAM (Random Access Memory), various interfaces, and a program ROM 46a. This control circuit 46 is supplied with the output signals of the receive sensor 42 and the touch switch 41, and as described above,
The output signals of sensors B5l-B53 are supplied. Furthermore, a humidity sensor 4 is installed near the filter 6.
7 (see Figure 1), this humidity sensor 4
The output signal No. 7 is also supplied to the control circuit 46. This control circuit 46 receives the output signals of the above-mentioned sensors and touch switches 41, and the program ROM 4.
Based on the program in 6a, the rotation of the fan 20, the motor controller MC, the clutch controller CCI~
Controls the heat generation of the heaters in the CC 3 and the grill chamber 5, respectively.

In this case, since the control of the control circuit 46 varies depending on the usage situation and place of use, the ROM l 6 a
As such, those that have stored programs corresponding to these are used. The ROM 16a is removable, so that if there is a change in usage conditions, it can be replaced with a corresponding one.

The alarm circuit 45 is a circuit that generates an alarm sound signal or a message sound signal under the control of the control circuit 46 and supplies it to the speakers 43, 441. This alarm circuit 45 generates an alarm sound, and
Predetermined message voice, e.g. "Liquid level is low"
, ``Please replenish the liquid'', etc., are configured separately, and the entire circuit board can be replaced at any time.

Next, reference numeral 55 (not shown in FIG. 1) is a grid-shaped plate member provided on the head frame 22.
Used when the top surface of 2 is used as an ashtray.

(2) Operation of the embodiment (2-1) Operation of the spray controller 31 Next, the operation of this embodiment with the above configuration will be explained.

First, when the control circuit 4G drives the fan 20, air is taken in through the air filter 6, and this air is sent out along the lower surface of the head frame 22 through the grill chamber 5 and the mix chamber 21.

Here, the programs stored in the program ROM 46a include the bottles 131, 132 . Assume that the program is to sequentially and cyclically select I33. In this case, first, the control circuit 46 supplies a motor drive signal to the motor controller MG to control the spray motor SPM.
While rotating the clutch controller CCl-
By supplying a control signal to CC5, the piston clutch PCI
is in the engaged state, and piston clutches PC2 and PC3 are in the disengaged state. As a result, the spouting part SP1 is driven and the bottle Bl
After sucking up a predetermined amount of the liquid inside, it is ejected in the form of mist from the nozzle tip TI via the lead pipe RPI. Now, if the liquid in the bottle Bl is a deodorant, this deodorant is sprayed into the mix chamber 21 in the form of a mist.
Here it is mixed with air. Since this mixed air is sent out along the lower surface of the head frame 22, unpleasant odors in the room where this device is installed are eliminated.

This deodorant jetting operation is performed for a predetermined period of time according to a program.

Next, the control circuit 46 puts the piston clutch PC2 in the engaged state and the piston clutches PCI and PC3 in the disengaged state in the same way as in the case described above, performs an operation to eject the liquid in the bottle B2 for a predetermined time, and after this operation, the piston Clutch PC3 is placed in the engaged state, piston clutches Pct and PC2 are placed in the disengaged state, and the liquid in the bottle B3 is ejected for a predetermined period of time. Assuming that the bottles [32 and I33 each contain an air freshener and water, the above operation will first spread a pleasant scent into the room, and then humidify the room.

In this way, the deodorizing operation, the fragrance operation, and the humidifying operation are automatically and sequentially performed cyclically according to the program in the program ROM 46a.

The liquid ejection operation of the ejection parts SPI and SP2.8P3 in the above operation includes an operation of pulling the piston to the maximum stroke to suck the liquid, and then pushing the piston to the end to send out the liquid (hereinafter referred to as maximum stroke operation). The action of pulling the piston to its maximum stroke to suck in the liquid, then pushing the piston intermittently a predetermined amount at a time to send out the liquid (
There is an operation (hereinafter referred to as "intermittent extrusion operation") in which the piston is pulled a predetermined amount in advance to suck the liquid, and then the piston is pushed all the way to send out the liquid (hereinafter referred to as "micro stroke operation"). Piston drive control in each operation is
The rotation of the spray motor SPM is controlled while feeding back the position of the piston using the output signals of the sensors B5l-B53.

Also, which of these operations to perform is stored in the ROM 46a.
Selected by the program within.

Also, bottle [31, B2. The ejection operation of the liquid in B3 is as follows:
Each is performed for a set time, but even during this time, the maximum stroke operation, intermittent extrusion operation, and minute stroke operation may be performed continuously or intermittently. It is set in advance depending on the situation, installation location, etc.

(2-2) Operation of grill chamber 5 Next, the operation and function of grill chamber 5 will be explained.

Solid deodorant 11 set in grill chamber 5
Since the solid air freshener 12 has a deodorizing effect and an aromatic effect at room temperature, when the fan 20 is driven, the air supplied through the air filter 6 inevitably contains deodorizing components and aromatic components. mixed in. Further, if an antibacterial agent (liquid) is stored in the lower part of the grill bat 7, the Japanese paper 15 sucks it up, so that the air taken in is mixed with the antibacterial component. The above-mentioned deodorizing components, aromatic components, antibacterial components, etc. are inevitably mixed into the air when the fan 20 is driven, and the control circuit 46 cannot control whether or not they are mixed in or stopped.

Regarding these, mixing and stopping of mixing of the relevant components is determined depending on whether or not a necessary agent is set.

Next, since the solid insecticide 10 and the solid fragrance 13 do not emit their respective components at room temperature, these components will not be mixed into the air simply by driving the fan 20. Current is supplied to the heater 8 or heater 9 by the control circuit 46, and the solid insecticide lO and the solid fragrance 13 are supplied with electric current.
When heated, the heat causes each component to be released, thereby introducing insecticidal or aromatic components into the air.

In this way, the mixing and stopping of the components of the solid insecticide 10 and the solid fragrance 13 are controlled by the control circuit 46.

(2-3) Manual operation The above operations were automatic operations based on the program in the ROM 46a, but in this embodiment, desired operations can be performed manually.

First, by operating a predetermined switch in the touch switch 41, the operation based on the program of the control circuit 46 is interrupted. Next, the switch in the touch switch 41 is operated to instruct driving/stopping of the fan 20, attachment/detachment of the piston clutches PC1 to PC3, power supply to the heaters 8 and 9 in the grill chamber 5, etc.

After these manual operations are completed, the touch switch 41 is operated again to return the control circuit 46 to operation based on the program.

Furthermore, by operating the transmitter 50, the same process as that of the touch switch 41 can be performed remotely.

In addition, when used in hospitals etc., bottles I31, 132. It is preferable to use a bacteriostatic agent as either the I33 or the liquid stored in the bottom of the grill chamber 5.

Further, in the above embodiment, the upper surface of the head frame 22 is used as an ashtray, but it may also be used as a vase or as a storage shelf for storing spare liquid for squirting.

``Effects of the Invention'' As described hereinafter, according to the present invention, there is provided a blowing means that takes in air from an intake port and sends out the taken air through a predetermined ventilation path, and a plurality of blowing means in which liquid is stored. If you select one of these liquid storage areas, the system will draw liquid from the selected liquid storage area,
Since the device is equipped with a liquid selective ejection means that makes the sucked up liquid into a mist and ejects it into the ventilation passage, various solutions can be put into the liquid storage part, and various solutions can be used for fragrance, deodorization, humidification, etc.
