[0002]

2. Description of the Related Art Conventionally, a rotating body having blades is attached to an aerosol container body, and by pressing a button provided on the aerosol container body, the sprayed content is applied to the blades of the rotating body to rotate the rotating body. The aerosol container itself by hanging the aerosol container body with a thread or the like, and rotating the aerosol body itself by the injection pressure of the content sprayed from the button provided on the aerosol container body. Attempts have been made to spread the mist sprayed at the time of use over a wide range as much as possible, but it was practically impossible to commercialize due to insufficient rotation or poor spray workability.

[0003] In addition, there has been an attempt to provide a rotating body at an injection port such as an actuator button and to directly rotate the rotating body to diffuse the mist. Only high products, such as those whose contents are made of only propellants such as liquefied gas, are barely spinning, and contain other active ingredients in addition to propellants as contents such as general products For products with low internal pressure, the rotation was insufficient or did not rotate at all, and it was practically impossible to commercialize the product.

[0006]

Next, an embodiment of the present invention will be described with reference to the drawings. 1 to 5 show a rotary actuator button device according to a first embodiment of the present invention. FIG. 1 is a plan view of a rotary actuator button device according to a first embodiment, and FIG. 2 is a longitudinal sectional view taken along line AA ′ of FIG. FIG.
FIG. 3 is a partial longitudinal sectional view showing a state in which the apparatus of the present invention in which the rotary actuator button device of FIG. FIGS. 4 and 5 are external perspective views of the first embodiment of the present invention in which the rotary actuator button device of FIG. 2 is attached to the aerosol container main body 12 and the cover cap 18 is attached, and FIG. FIG. 5 is a perspective view showing the appearance of the apparatus of the present invention when the apparatus of the present invention is injecting operation, that is, the state of FIG.

In FIGS. 2 and 3, a slide pipe 1 is connected to a rotary shaft nozzle 7 of a fixed shaft body 4 through an O-ring 6.
The stopper ring 5, which is a stopper for the slide pipe 10, is fitted at the upper end of the rotary shaft nozzle 7. The rotary wing body 1 is fitted and fitted to the slide pipe 10. An injection nozzle 3 having an injection port 2 is provided at an end of the rotary wing body 1.

Here, when the rotary actuator button device of the present invention is attached to the aerosol container main body 12 and the push button 8 is depressed with a finger and the device of the present invention is ejected, the liquid in the aerosol container main body 12 is filled with a valve. The nozzle orifice 9 of the nozzle 7 serving as a rotary shaft passes through the stem 13.
Erupts from And the top-to-face portion 1 inside the rotor 1
5 is pushed up by the injection pressure of the content liquid, the rotary wing body 1 rises along the rotary shaft nozzle 7,
That is, it rises to the position as shown in FIG. 3, and rotates by the ejection power of the ejection of the content liquid from the ejection port 2 of the ejection nozzle 3. At this time, as shown in FIGS. 4 and 5, if the push button locking claw 20 is attached to the cover cap 18, the push button 8 is held while being pushed down, so that the rotary wing body 1 is as shown in FIG. The rotation is continued at the position, and the liquid in the aerosol container body 12 is continuously jetted.

In the conventional method in which rotation is started only by the injection force from the nozzle, the initial frictional resistance from static to dynamic at the beginning of movement is too large, and the aerosol is required for the rotor blade to rotate normally. Although the contents in the container body were limited to a propellant with a high vaporization rate and a high vaporization rate, it was impossible to actually commercialize the container. When the rotating wing body 1 starts rotating, the initial frictional resistance first shifts from static to moving, so that the initial rotation from the stationary state between the fixed shaft body 4 and the rotating wing body 1 to the start of rotation. The frictional resistance is remarkably reduced, and the rotating blade body 1 is smoothly rotated by the slight jetting power of the content liquid from the injection port 2 of the injection nozzle 3 provided on the rotating blade body 1 to the rear.

The internal pressure of aerosol products is usually 2 to 7 kg /
It is manufactured in the range of cm ² (25 ° C.). For example, in a product having an internal pressure of 4 kg / cm ² (25 ° C.),
The ejection force ejected from the ejection port 2 of the ejection nozzle 3 is
Even when the diameter of the nozzle is 0.5 mm, the rotational injection force is only about 0.1 kg (when the distance from the fulcrum is not taken into consideration per one nozzle). However, in the product embodying the present invention, both the output power and the rotational force of the content liquid to the rear from the injection port 2 are increased by the rising force of the rotating blade body 1, and the fixed shaft body 4 and the rotating blade body 1 are also added. Then, the following force is applied because the moving state from the stationary state to the moving state until the rotation starts. That is, for example, if the diameter of the top-facing portion 15 inside the rotary wing body 1 is 5 mm, about 1 k
Since a lift force of g occurs, as described above, the state where the stationary shaft body 4 and the rotary wing body 1 are brought into a dynamic state for starting rotation from a stationary state depends only on the injection force from the nozzle 2. By comparison, the lift of the injection nozzle top 14 is added,
The initial frictional resistance between the stationary shaft body 4 and the rotary wing body 1 from the stationary state to the start of rotation is significantly reduced.

FIGS. 6 and 7 show a second embodiment of the present invention. FIG. 6 is a partial longitudinal sectional view of the second embodiment, and FIG. 7 is an external perspective view showing an example of an uneven fin 17 serving as a propeller or a turbine blade shown in the second embodiment of FIG. FIG. FIG. 6 shows a top-to-face portion 15 inside the rotor 1.
In addition, an uneven fin 17 for serving as a propeller and a turbine blade is provided, and a vertical groove 19 is provided in the rotary shaft nozzle 7 so that the positioning pin 16 attached to the slide pipe 10 is engaged with the slide pipe 10. This is so as not to come off from the rotary shaft nozzle 7.
In FIG. 6, a vertical groove 19 is provided in a part of the rotary shaft nozzle 7, and the slide pipe 10 is fitted so as to move up and down along the rotary shaft nozzle 7. A pin 16 is inserted and fitted into the lower part of the slide pipe
The slide pipe 10 moves within the range of the length of the groove. The rotary wing body 1 is fitted and mounted on the upper part of the slide pipe 10, and an uneven fin 17 is provided on the top-facing portion 15 inside the rotary wing body 1.
In FIG. 6, a valve stem fitting hole 11 and a valve stem 13 below the rotary shaft nozzle 7 are connected to an aerosol container body 12 provided with a tilt valve.

In this state, the side of the fixed shaft 4 is pushed in a state of being attached to the aerosol container 12, and the valve stem 13 of the tilt valve is operated to inject the liquid in the aerosol container main body 12, thereby injecting the apparatus of the present invention. When you let
The liquid content of the aerosol container body 12 passes through the valve stem 13 and is ejected from the nozzle orifice 9. Since the top-to-face portion 15 inside the rotary wing body 1 is pushed up by the jet pressure of the liquid content, the rotary wing body 1 is rotated by the rotary shaft nozzle 7.
And the rotor 1 rotates at the raised position. As the rotary wing body 1 rises, similarly to the first embodiment, the transition from static to dynamic, that is, the initial frictional resistance from the stationary state between the fixed shaft body 4 and the rotary wing body 1 to the start of rotation. Is remarkably reduced, and the rotary wing body 1 rotates smoothly due to the slight output power of the liquid content from the injection port 2 of the injection nozzle 3 provided on the rotary wing body 1.

Here, in FIG. 6, an uneven fin 17 for serving as a propeller or a turbine blade is provided in the top-facing portion 15 inside the rotary wing body 1, so that the nozzle of the rotary shaft nozzle 7 is used. When the content liquid is ejected from the injection port 9 toward the top facing portion 15 into the rotary wing body 1, the content liquid hits an uneven fin 17 for performing a function such as a propeller or a turbine blade. Rotor wing body 1
The force to turn works. Therefore, the rotational force obtained from the liquid content injected from the injection nozzle 2 of the injection nozzle 3 of the rotary wing body 1 is reinforced, and the rotational force of the rotary wing body 1 is stronger than in the case of only injection from the injection nozzle 2. Becomes

The moving distance (length) of the rotary wing body 1 for moving the rotary wing body 1 up and down can be arbitrarily determined by the length of the vertical groove 19 of the rotary shaft nozzle 7 and the position of the stopper ring 5. The length of the rotor 1 may be several centimeters to several tens of centimeters, so that the rotor 1 can be seen up and down in accordance with the condition.
The movement may be as short as a few millimeters.

The O-ring 6, which is provided for the purpose of preventing leakage of the content liquid from the gap between the slide pipe 10 and the rotary shaft nozzle 7 at the time of injection, passes through the valve stem 13 and the content injected from the nozzle injection date 9. The ejection amount of the liquid is equal to the ejection amount of the content liquid discharged to the outside from the nozzle 2, or the ejection amount of the content liquid ejected from the nozzle hole 9 through the valve stem 13 is discharged to the outside from the nozzle 2. When the adjustment is made to be slightly smaller than the ejection amount of O, the O-ring is unnecessary because there is almost no leakage from the vicinity of the O-ring 6.

The number of injection nozzles 3 provided on the rotary wing body 1 is related to the rotational force to some extent, but if the size (discharge amount) of the injection port 2 is large enough to obtain the rotational force, it can be ensured. One or more arbitrary number of nozzles 2 can be provided, and the rotor 1 can be freely manufactured in consideration of design and balance. Further, the mounting position of the injection nozzle 3 may be such that the injection direction of the injection port 2 causes the injection to be performed backward with respect to the rotation direction. On the other hand, it is also possible to attach it on both sides.

The shape of the rotary wing body 1 may be rectangular as viewed from the top as shown in FIG. 1, or it may be a circle as shown in FIG. 9, a triangle as shown in FIG. It can be made in any shape, such as star and star. Needless to say, one or more arbitrary number of nozzles can be provided as described above. FIG. 9 is a plan view showing an example in which the injection nozzle 2 is formed by directly forming a hole in the rotor blade 1 obliquely in order to integrate the injection nozzle and the circular rotor body, and the injection date of the rotor blade 1 is set. is there.

The smaller the shaft diameter of the portion of the fixed shaft body 4 serving as the rotation shaft of the nozzle 7 serving as the rotation shaft, the better, and preferably 15 mm or less. Preferably, the diameter is set to 1 mm or more and 10 mm or less, since the rotation resistance of the rotary wing body 1 is small and the rotation operation is stable. If the diameter is 15 mm or more, the rotation resistance is too large, and some liquids are difficult to rotate. If the diameter is 1 mm or less, it is difficult to commercialize and the workability is poor.

When the present invention is applied to a smoke agent, a bactericide, or the like, as shown in the embodiment of FIGS.
There is a case where the push button locking claw 20 is attached to 8 and the continuous ejection is performed with the push button 8 set.
In such a case, there is a case where it is better to set the push button 8 so that the liquid content can be ejected for a while afterward so as not to inhale the chemical liquid or settle on the face at the time of setting. In such a case, a delay injection device for delaying the start of the injection operation of the content liquid can be attached and used between the rotary actuator button device of the present invention and the aerosol container body 12.

The position of the injection port 2 of the rotary wing body 1 is provided outside the outer diameter of the nozzle injection port 9 of the rotary shaft nozzle 7 serving as the rotation axis of the rotary wing body 1, and the center of the nozzle 7 At least 3 mm or more is required between the position and the injection port 2 of the rotary wing body 1, and if the outer diameter of the rotating shaft is within 1 to 10 mm, the rotary wing body 1 can obtain extremely smooth rotation. Can be done.

[0021]

According to the conventional method in which rotation is started only by the injection force from the nozzle, the initial frictional resistance from static at the beginning of the movement to the movement is too large, and the rotating blade body rotates normally. Has limited the propellant content in the body of the aerosol container to a high pressure and a high vaporization rate, making it impossible to actually commercialize it. By the present invention that shifts to the frictional resistance of the fixed shaft body and the rotary wing body, the initial frictional resistance from the stationary state to the start of rotation from the stationary state is significantly reduced, so that the rearward from the nozzle provided on the rotary wing body. The rotating blade body is smoothly rotated by the slight ejection power of the liquid content. When using a product that implements the present invention,
Not only the sprayed contents liquid is diffused in a wide range to enhance the effect effect, but also when the push button is pressed to perform the spraying operation, the appearance that the rotary wing body rises and starts the spraying adds to the enjoyment of the spraying and the spraying.
