Description

[Detailed description of the invention] [Industrial application field] This invention can be installed in entrances, washrooms, or gathering places, or used for demonstrations of new cosmetic spray products.
This invention relates to a device that automatically sprays fragrances, deodorants, etc. from a spray container.

[Conventional technology]

As an example of this type of automatic spraying device, there is one shown in FIGS.
No. 178122). There, on the front of main case 1,
A recess 3 is formed in which a pump-type or aerosol-type spray container 2 is accommodated. A pusher 6 for pressing the spray head 4 of the spray container 2 is installed in the upper part of the recess 3, and the pusher 6 is driven by a sensor that detects external changes, such as an infrared sensor, or a microphone that picks up sound. Automatically controls by receiving signals from temperature sensors, etc. Thus, when the spray head 4 is automatically pressed with the pusher 6, the liquid fragrance or deodorizer contained in the spray container 2 is directed from the spout hole 5 of the spray head 4 toward the front of the main body case 1. It is starting to come out in the form of a mist.

Also, although not shown, when the spray container is placed on the main body case and the switch is turned on, the pusher descends due to the operation of the solenoid and presses the spray head on the spray container, which releases the fragrance inside the spray head. A form of automatic jetting periodically from a jet hole is known from Japanese Utility Model Publication No. 56-33544.

However, in the automatic spraying devices having the above-mentioned basic configuration, the spray container 2 is fixed on the main body case 1, and the spray hole 5 of the spray head 4 is kept facing in a fixed direction in front, so that the air freshener etc. can be sprayed out. The direction is specified. Therefore, there was a problem in that a single device could not provide a sufficient aromatic or deodorizing effect, especially in places where people come and go frequently, such as meeting halls and dance classes, and where it is installed in halls.

Regarding this point, another conventional example is
Publication No. 179141 discloses that while a spray container placed on the main body case is rotated by a drive source such as a spring, the spray head is pressed by a pusher on the main body case side, and the aromatic agent etc. inside are released from the spray head. It has become something that gushes out. According to this, the ability to continuously eject fragrances and the like while changing the ejection direction over a wide range can be evaluated.

[The problem that the idea attempts to solve]

However, the automatic spraying device disclosed in the above-mentioned Japanese Utility Model Publication No. 58-179141 has a configuration in which the entire spray container is rotated on the main body case, and since the entire spray container is heavy, it is driven to rotate. The mechanism is complicated and large, and the production cost is high.

Also, during continuous spraying, the pusher on the main body case side must continue to press the spray head on the spray container. In this case, if the spray container is rotated while receiving this pressing force, the bottom structure on the spray container side must also be made special to ensure that it receives the rotational driving force. Since this type of spray container is intended to be disposable, it is also expensive and not a good idea.

Additionally, this type of spray container has a label affixed to the front that also serves as an indication of the contents, but if the spray container rotates with its main body, it is inconvenient that it becomes difficult to recognize the label before and during use. .

Therefore, an object of the present invention is to provide an automatic spraying device that can automatically spray fragrances, etc. from a spray container forward at a wide angle while changing the direction.

Another object of the present invention is to provide an automatic spraying device that can automatically change the direction of ejection of fragrance, etc. using a simple and rational mechanism.

[Means to solve the problem]

As shown in the figure, the automatic spraying device for air fresheners, etc., according to the present invention has a recess 3 formed in the front of the main body case 1 to accommodate the spray container 2 so as to be freely put in and taken out, and the spray container 2 has a spout hole at the top. A spray head 4 having a spray head 5 is mounted so as to be vertically movable and rotatable, and by pressing the spray head 4 downward, the liquid aromatic agent, etc. inside is sprayed from the spray hole 5. In particular, a pusher 6 is installed at an upper position in the recess 3 of the main body case 1 so as to be able to move up and down and freely turn. The pusher 6 has a means for holding the pusher 6 in a position below the pusher 6, a drive means for moving the pusher 6 up and down is provided on the main case 1 side, and a drive means for moving the pusher 6 up and down is provided between the pusher 6 and the spray head 4. The lower end is provided with an engaging means that engages with the spray head 4 in a detachable but non-rotating manner, and as the pusher 6 is lowered, the pusher 6 is connected to the spray head 4. It is required that head turning means be provided for turning the head while being engaged with the head.

[Effect]

When the spray container 2 is positioned and housed in the recess 3 of the main body case 1 and the pusher 6 is pushed down by a driving means such as a motor, the pusher 6 descends while rotating. The lower end of the pusher 6 engages with the spray head 4 on the spray container 2 in a non-rotating manner (relatively unrotatable);
In this engaged state, only the spray head 4 is oscillated and pushed downward. The main body portion of the spray container 2 is held in the main body case 1 in a non-swiveled state.

When the spray head 4 is pushed downward, the aromatic agent, etc. in the container is sprayed out from the spray hole 5 provided in the spray head 4. At the same time, the spray head 4 rotates, so that the direction in which the fragrance and the like are ejected changes over a wide angle.

[Effect of idea]

As described above, according to the present invention, when the spray container 2 is set in the recess 3 of the main body case 1, the spray container 2
Since only the spray head 4 is rotated and pressed by the pusher 6 on the main body case 1 side while being held in position, the aromatic agent, etc. in the spray container 2 is ejected from the spray hole 5 of the spray head 4 in the direction This means that the spray can be ejected over a wide area while changing the amount of water, and the fragrance or deodorizing diffusion effect can be fully exerted even in a large installation location.

In order to press the spray head 4 while rotating it, it is sufficient to provide only a drive means for vertically moving the pusher 6 on the main body case 1 side, and a head rotating means for rotating the pusher 6 as it is lowered. In other words, the spray container 2 is positioned and held in the recess 3 of the main body case 1, and the pusher 6 is used to rotate and press only the spray head 4. Therefore, since the light and small spray head 4 is simply moved via the pusher 6, the mechanism for operating the pusher 6 can be simplified in structure, and the means for driving the pusher 6 does not require large power. Moreover, on the side of the spray container 2, it is only necessary that the spray head 4 is rotatable and receives a downward force, and there is no need to make the bottom structure of the spray container 2 special. As a result, these methods can be implemented at low cost.

Furthermore, since the spray container 2 itself does not rotate when it is set in the recess 3 of the main body case 1, it is convenient to keep the front label of the spray container 2 easily visible at all times.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 6.

A front-open recess 3 is formed on the front surface of the main body case 1, which is formed in the shape of a vertically elongated rectangular tube, to accommodate the spray container 2 so as to be freely inserted and removed in the front and rear directions. A slide presser plate 9 is attached to the bottom surface 8 of the recess 3 of the main body case 1 so as to be freely inserted and removed in the front-rear direction. It is arranged to be accommodated and held at a predetermined position located at a lower position.

The above-mentioned spray container 2 is of a pump type, and a spray head 4 having an ejection hole 5 is attached to the upper part of the container 2 so as to be movable up and down and freely rotatable. is activated, and the liquid fragrance or deodorant inside is sprayed out from the spout hole 5 in the form of a mist. A rectangular recess 10 is provided on the upper end surface of the spray head 4.

At a predetermined position on the upper ceiling wall 3a in the recess 3 of the main body case 1, a cylindrical pusher 6 that presses the spray head 4 of the spray container 2 moves straight up and down by a predetermined stroke via a pusher 7. Supported in a slidable manner. Further, the pusher 6 has a protrusion 11 having a rectangular cross section that fits into the recess 10 of the spray head 4 at its lower end, and has a spiral groove 12 on its circumferential surface. On the other hand, the slider 13 is on the ceiling wall 3a.
is fixed and slidably fitted into the spiral groove 12.

Further, a container holding plate 14 is fixed to a midway in the height direction within the recess 3 of the main body case 1, and a notch is provided at the front end of the container holding plate 14 to accommodate the neck portion of the spray container 2 below the spray head 4. 15 is provided to more reliably prevent the container 2 from falling over.

In such a case, when the pusher 6 is pushed straight downward by a drive means to be described later, the pusher 6 descends while rotating in the spiral groove 12 while being guided by the slider 13 and moving the protrusion 11 towards the spray head 4. The spray head 4 is fitted into the recess 10 in a non-rotating manner and pushed downward while swinging by a predetermined angle (within the width of the front opening of the recess 3). Then, the spray container 2 sprays the aromatic agent etc. in a diffused manner toward the front of the recess 3 from the spray hole 5 of the rotating spray head 4.

The driving means for the pusher 6 comprises a motor 16 and a motion conversion mechanism 17 that converts the rotational motion of the motor 16 into vertical linear motion of the spray head 4.
A geared motor is used as the motor 16, and a battery 18 is built in below the recess 3 in the main body case 1.
is the power source. Six AA batteries 18 are housed in series in a battery chamber 19 provided at the bottom of the case below the motor 16 in the main body case 1.

The motion conversion mechanism 17 is configured as follows. A rotating shaft 20 is supported by a bearing 21 in line with the motor 16, and a gear 23 on the motor shaft 22 and a gear 24 at one end of the rotating shaft 20 are meshed to transmit the rotation of the motor 16 to the rotating shaft 20. Also, the gear 24 at one end of the rotating shaft 20 and the disc 25 at the other end
A crank pin 26 is provided protrudingly at an eccentric position on each side. A gate-shaped connecting rod 27 is installed in the main body case 1 so as to be vertically movable via a guide 28 so as to straddle the top wall 3a of the recess 3 and the left and right inner walls 3b, 3b. The connecting rod 27 has left and right legs 27a, 27a guided by a guide 28.
The left and right legs 27 are located above the ceiling wall 3a.
a, 27a, and a head 27b connecting the upper ends of the left and right legs 27a, 27a, and a long hole 29 that is long in the front-rear direction is formed at the lower end of each of the left and right legs 27a, 27a. The connecting rod 27 slidably engages the long holes 29, 29 of the left and right legs 27a, 27a in the crank pins 26, 26, respectively, and integrally connects the upper end of the pusher 6 to the head 27b. are doing. Thus, the rotation of the rotating shaft 20 causes the crank pin 26 to slide within the elongated hole 29, and the connecting rod 27 moves into the guide 28.
Move up and down through. Pushya 6 is the connecting rod 2
Along with the vertical movement of the head 7, the spray head 4 is similarly moved up and down to press the spray head 4.

For automatic control of the motor 16, a sensor that detects a certain registered voice, that is, a microphone 30 is installed above the recess 3 on the front side of the main body case 1.
is provided, and receives an output signal from the microphone 30 to control the motor 16.

A counter switch 31 is installed near the upper part of the head 27b of the connecting rod 27 to count the number of operations performed as the connecting rod 27 moves up and down, so that the motor 16 is stopped at a predetermined count. I have to.

[Another example]

In the above embodiment, the pusher 6 is provided with a protrusion 11 having a rectangular cross section, and the protrusion 11 is provided on the upper end surface of the spray head 4.
However, on the contrary, as shown in FIG.
It may be formed into a rectangular cross section that fits into the 0.

Alternatively, as shown in FIG. 8, a notch 32 having a rectangular cross section may be provided on the rear side of the spray head 4, and the pusher 6 may be formed to have a rectangular cross section to fit into the notch 32. According to this, a state can be obtained in which the spray container 2 is housed in the recess 3 from the front and the spray head 4 is fitted into the pusher 6 at the same time.

In another embodiment shown in FIG. 9, a straight vertical groove 33 is continuously provided in the vertical direction at the lower end of the spiral groove 12 provided on the circumferential surface of the pusher 6 of the above embodiment, and the pusher 6 is formed in the vertical groove 33. Slide the slider 13 straight downward so that the protrusion 11 is in the recess 10 on the upper end surface of the spray head 4.
The spray head 4 is rotated while being pushed down only after the spray head 4 is completely fitted into the interior.

In another embodiment shown in FIG.
A spiral groove 12 is provided in a zigzag shape on the circumferential surface of the spray head 4 so that the spray head 4 can reciprocate within a predetermined angle range as the pusher 6 descends once.

In another embodiment shown in FIG. 11, the bottom 3c in the recess 3 of the main case 1 is configured separately from the main case 1 and is movable up and down with a spring 34, so that the spray container 2 is recessed. When placing the spray container 2 on the bottom surface 3 of the container 3, the spray container 2 should be placed on the bottom surface 3c so that the spray head 4 does not come into contact with the pusher 6 and interfere with it.
When the entire spray container 2 is lowered against a spring 34 and then raised as a whole by the force of the spring 34, the lower end surface of the pusher 6 fits into the recess 10 on the upper end surface of the spray head 4.

Further, the spray container 2 may be of an aerosol type instead of the above-mentioned pump type, and in short, it is capable of spraying a liquid aromatic agent, deodorizer, etc. sealed inside by pressing the spray head 4. That's fine.

As a driving means for moving the pusher 6 up and down,
Instead of using the illustrated example of the motor 16, the pusher 6 may be operated by a solenoid. The motion conversion mechanism 17 may be a slider/crank mechanism, a cam mechanism, a rack pinion, or the like.

Further, the operation of the motor 16 or the solenoid is controlled by receiving signals from a sensor that detects an external change, such as an optical sensor such as an infrared sensor, a microphone that picks up a specific sound, a temperature sensor, etc. It is optional to do so or to simply control them on and off with a power switch.

Furthermore, in addition to a method in which the spray head 4 is rotated while spraying, a method in which the spray head 4 is intermittently rotated at a constant angle and sprays when the head 4 is stopped is also conceivable.
