Description

Air freshener

The present invention relates to an air freshener, and more particularly to an air freshener that is installed in a space such as a toilet so that the efficacy of a chemical solution is continuously drifted.

Conventionally, air fresheners have been developed that make the air environment of a toilet or the like a favorable state by aroma or deodorization. That is, the air freshener is an fragrance or fragrance device that sprays a fragrance into a space, or a deodorizer or deodorizer that sprays a deodorant.

In the case of the above fragrance or deodorizer, the fragrance or deodorant is simply filled in the container. For example, in a fragrance device, a fragrance is naturally evaporated and diffused, so that a portion with a strong fragrance or a portion with a weak fragrance can be created in the indoor space. In particular, in the case of a wide space, it is difficult for the fragrance to spread uniformly throughout the space. The same is true for the deodorizer.

In order to solve the above problem, for example, in Patent Document 1, the air freshener and deodorant are uniformly distributed not only in a narrow space such as a toilet in a general household but also in a large space such as a toilet in a hotel or restaurant. A device that can be used as a fragrance device or a deodorization device that has been devised to spread is disclosed. That is, a container filled with a liquid fragrance or the like is disposed inside a main body case having a suction port and a blower outlet, and the liquid fragrance or the like in the container is located between the air suction port and the discharge port in the main body case. It arrange | positions so that it may diverge to the air flow-path part. And by the drive of the electric fan arrange | positioned at an air flow-path part, the flow of air is produced between the said suction inlet and the said blower outlet.

When the electric fan is driven, air is sucked from the suction port into the air flow path. The air forcibly evaporates the liquid fragrance or the like in the container and diffuses it, and blows it out from the outlet. In this way, the interior of a toilet or the like is filled with fragrance or deodorized.

JP-A-5-329199

The device that diffuses the fragrance and the deodorant disclosed in Patent Document 1 is effective in that the fragrance and the like are spread uniformly over a wide space, but the fragrance evaporated from the container Since the chemical solution is blown out to the outside by an electric fan, only the components that easily evaporate are easily consumed first. For this reason, the fragrance is often scented at the beginning of installation of the container, but there is a problem that the fragrance fades with time.

The present invention has been made in view of the above, and is capable of stably acting the effects of chemical solutions such as fragrances and deodorants over a long period of time, and the chemical solution is distributed as uniformly as possible to a wide indoor space. It is an object of the present invention to provide an air freshener that sprays chemicals such as fragrances and deodorants that can be spread.

In order to solve the above-described problems, the air freshener of the present invention can inject air at a chemical solution nozzle connected to a chemical solution container storing a chemical solution via a chemical solution tube and outside the discharge port of the chemical solution nozzle. And an air nozzle for diffusing the chemical liquid discharged from the chemical liquid nozzle in the form of a mist, and an air supply device for injecting air from the air nozzle.
The air nozzle is provided outside the discharge port of the chemical solution nozzle so as to be able to inject air from a direction substantially orthogonal to the discharge direction of the chemical solution from the discharge port. It is preferable that the chemical liquid in the container is sucked and discharged from the discharge port of the chemical liquid nozzle, and the discharged chemical liquid is diffused.

Furthermore, it is also possible to have a configuration in which a chemical solution supply device is provided, the chemical solution supply device supplies the chemical solution stored in the chemical solution container to the chemical solution nozzle, and the chemical solution is discharged from the discharge port.
It is preferable that the air nozzle is arranged so that the air injection direction is in a positional relationship that is substantially orthogonal to the discharge direction of the chemical liquid from the chemical liquid nozzle.
It is preferable that the air nozzle is arranged to inject air in an obliquely upward direction. The air nozzle is preferably arranged such that the air injection angle is obliquely 30 to 60 degrees above the horizontal direction. It is preferable that the air supply device has a configuration in which a driving time is controlled by a control unit. The driving time of the air supply device may be controlled based on a signal output by an illuminance sensor that detects illuminance.

According to the present invention, the chemical liquid discharged from the chemical liquid nozzle comes into contact with the air ejected from the air nozzle. This air is preferably injected obliquely upward with respect to the horizontal direction. As a result, the chemical liquid collides with the air ejected from the air nozzle, and the chemical liquid becomes a fine mist. The mist of the chemical solution is blown away by the air sprayed from the air nozzle. That is, since the chemical liquid discharged from the chemical liquid nozzle is blown away by the air outside the chemical liquid nozzle, almost all components of the chemical liquid discharged from the chemical liquid nozzle are always diffused. In addition, since the chemical liquid is configured to collide with air outside the chemical liquid nozzle, the chemical liquid mist becomes extremely fine and can be floated in the air for a long time, so that the effectiveness of the chemical liquid is prolonged in a wide area.

Also, the air nozzle has its air injection angle inclined at an angle of 30 ° to 60 ° with respect to the horizontal direction, so that the mist of the chemical solution can be further diffused and diffused in the air.

The control unit can automatically spray the chemical liquid at a predetermined time, for example, by setting the time of air injection with a timer. Furthermore, since there is almost no use at night in department store toilets, etc., by providing an illuminance sensor, it is configured to stop the air injection drive when it gets dark, and drive when it becomes brighter than the predetermined, Waste of chemicals can be eliminated.

Further, a compressor 54 is disposed near the back cover 20 in a range surrounded by the battery box 23. It should be noted that these arrangements are merely examples and are not limited to those shown in the drawings.

The lower cover 30 covers the front surface and both side surfaces of the upper shelf 22 and the battery box 23 supported by the back cover 20 in a state where the chemical container 12 and the battery 11 are disposed as described above. Is detachably provided.

On the other hand, the upper cover 40 covers the upper side of the lower cover 30 and is detachably provided on the back cover 20 and the lower cover 30. The upper cover 40 is formed to bend so as to be inclined downward from the rear to the front when viewed from the side (see FIGS. 9 and 10), and the nozzle portion 50 is formed on the front wall. The spray port 41 for the mist-like chemical | medical solution sprayed from to pass through and spraying outside is formed.

Further, inside the upper cover 40, a control board constituting the control unit 70 and an illuminance sensor 13 for detecting ambient illuminance are attached. The illuminance sensor 13 is electrically connected to the control unit 70 as shown in FIG. An illuminance sensor window 42 facing the illuminance sensor 13 is formed near the rear of the upper wall of the upper cover 40.

Next, the nozzle unit 50 that forms the main part of the present embodiment will be described in detail. As shown in FIG. 1, the nozzle unit 50 includes an air nozzle 51 that ejects air in an obliquely upward direction, and a chemical liquid nozzle 55 that discharges the chemical liquid LM, and the front wall of the upper cover 40 as described above. It faces the spray port 41 formed in the above. Further, the air nozzle 51 and the chemical liquid nozzle 55 are arranged such that the arrangement directions along the respective axes are substantially orthogonal. Further, the air sprayed from the air nozzle 51 is disposed so as to pass through the vicinity of the discharge port 55 a of the chemical liquid nozzle 55. More specifically, although it is outside the discharge port 55a of the chemical liquid nozzle 55, the air injection port 51a of the air nozzle 51 is disposed close to the discharge port 55a.

The air nozzle 51 communicates with an air supply device 53 via an air tube 52 (air supply pipe). The air supply device 53 includes a compressor 54, and passes necessary air (compressed air) through the air tube 52 through a control valve mechanism (not shown) incorporated as necessary. Supply. The compressor 54 constituting the air supply device 53 is electrically connected to the control unit 70 and is driven in response to a control signal from the control unit 70.

Further, the air nozzle 51 has its air injection angle θ directed obliquely upward by 30 ° to 60 ° with respect to the horizontal direction, so that the mist-like chemical liquid (mist M) is moved further into the air. It is preferable in terms of In particular, it is desirable to set to 35 to 55 degrees, and further to 45 degrees. The air nozzle 51 and the chemical solution nozzle 55 are arranged so as to face the spray port 41 formed in the upper cover 40. Of course, the spray port 41 is provided so as to open in the air injection direction of the air nozzle 51. is there.

The chemical nozzle 55 is connected to one end of a chemical tube 58 (chemical solution supply pipe). The other end of the chemical liquid tube 58 is inserted into the chemical liquid container 12 and is in contact with the chemical liquid LM. As the chemical liquid LM, as described above, a fragrance or a deodorant is used.

Next, the operation of the nozzle unit 50 will be described.
When the compressor 54 of the air supply device 53 is driven, air (compressed air) is sent to the air nozzle 51, and the air (compressed air) is injected at an air injection angle θ obliquely upward with respect to the horizontal direction. Is done. In the case where the illuminance sensor 13 is provided as in the present embodiment, when the illuminance sensor 13 detects that the predetermined brightness is reached, a control signal is sent from the control unit 70 to drive the compressor 54. .

When air (compressed air) is injected, the discharge port 55a of the chemical liquid nozzle 55 is close to the air injection port 51a of the air nozzle 51 as described above. The air passes so as to be substantially perpendicular to the discharge direction, that is, across the discharge direction. Accordingly, the vicinity of the discharge port 55 a of the chemical liquid nozzle 55 becomes negative pressure, and the chemical liquid LM in the chemical liquid container 12 is sucked through the chemical liquid tube 58 and discharged from the discharge port 55 a at the tip of the chemical liquid nozzle 55. The chemical liquid LM is discharged to the outside from the chemical liquid nozzle 55, and at the same time, the air injected from the air nozzle 51 that passes immediately before the discharge port 55a collides.

Diffused. In addition, if the injection pressure of the air injected from the air nozzle 51 is increased, the chemical solution mist M is further refined.

As described above, the chemical liquid LM is forcibly sucked and blown out from the chemical liquid container 12 through the chemical liquid tube 58 when air (compressed air) passes outside the vicinity of the discharge port 55a of the chemical liquid nozzle 55. Therefore, it is less likely that only a specific component in the chemical liquid LM is diffused as in the prior art, and a desired chemical effect can be stably exhibited over a longer period of time. In addition, since the sprayed mist M of the medicinal solution is refined and blown away, it will float in the air for a long time. Can be spread evenly.

Further, it is preferable that the control unit 70 is configured to automatically spray when a predetermined time is reached, for example, by setting a driving time for spraying the chemical liquid LM with a timer. On the other hand, when the air freshener 10 of the present embodiment is installed in, for example, a public toilet, it is not necessary to spray in a time zone that is not used by a person. Therefore, by providing the illuminance sensor 13 as described above, it is possible to reduce the waste of the chemical solution by adopting a configuration in which the spray driving is stopped when it becomes dark and the spray driving is performed when the brightness becomes a predetermined brightness or more.

This embodiment is different from the above embodiment in that a chemical liquid supply device 59 is interposed between the chemical liquid container 12 and the chemical liquid tube 58 (chemical liquid supply pipe). The chemical liquid supply device 59 includes a chemical liquid pump 61 that supplies the chemical liquid LM in the chemical liquid container 12, and the necessary chemical liquid LM is discharged through the chemical liquid tube 58 by driving the chemical liquid pump 61. The chemical pump 61 is driven by a motor 62, and the motor 62 is connected to the control unit 70.

Thereby, a predetermined amount of the chemical liquid LM is forcibly discharged from the discharge port 55 a at the tip of the chemical liquid nozzle 55 by driving the chemical liquid supply device 59. The air jetted from the air nozzle 51 collides with the chemical liquid LM discharged from the chemical nozzle 55 to the outside. Thereafter, similar to the above-described embodiment, the chemical liquid LM is in a mist shape, and is preferably miniaturized to 30 μm or less. The atomized mist M of the chemical liquid passes through the spray port 41 of the upper cover 40 according to the air pressure ejected from the air nozzle 51 and is blown off and diffused. It is to be noted that the discharge of the chemical liquid LM from the chemical liquid nozzle 55 has a simple structure, as in the above-described embodiment, forcibly sucked by setting the vicinity of the discharge port 55a of the chemical liquid nozzle 55 to a negative pressure. Therefore, it is preferable. However, depending on the performance of the compressor 54, that is, the pressure of the air jetted from the air nozzle 51, a configuration using the chemical pump 61 as shown in FIG.
