Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to atomizing perfume or other liquid in a liquid storage container and ejecting it into the air. In particular, if the liquid is removed from the liquid storage container, the liquid is sucked and poured. The present invention relates to a liquid sprayer capable of functioning as a dropper that can be used.

[0002]

2. Description of the Related Art There are various types of conventional atomizers used for perfumes and the like. FIG. 5 shows one of them, and the sprayer main body 3 is screwed to the mouth portion 2 of the liquid storage container 1 for use. The sprayer main body 3 has a thin suction pipe 6 at the tip (lower end) at the center of the lid 4 which can be screwed into the mouth 2 of the liquid storage container 1.
The fixed cylinder 5 is fixed so as to extend vertically, and the guide cylinder 7 is provided on the upper surface of the lid portion 4, and the movable cylinder 8 is rotatable in the guide cylinder 7. It is assembled so that it can move up and down, and inside the movable cylinder 8,
A large-diameter annular piston 9 is slidably fitted in the vertical direction, while a small-diameter annular piston 10 is slidably fitted in the fixed cylinder 5 so that both annular pistons 9,
A spring 12 in which 10 members are integrally connected by a flow path pipe 11 and are interposed between the upper surface of the lid portion 4 and the large-diameter annular piston 9.
Thus, the large-diameter annular piston 9 is always urged upward.

Further, the movable cylinder 8 is provided with a spiral groove 13 on its outer periphery so that it can be raised and lowered while rotating, and a ball 14 fitted in the spiral groove 13 is mounted on the upper end of the guide vertical cylinder 7. Further, an aerosol valve 15 having a stem protruding upward is provided on the upper end of the movable cylinder 8, and a push button 16 having a spray nozzle 17 is provided on the stem.
When the push button 16 is pushed down, the large-diameter annular piston 9 and the small-diameter annular piston 10 are lowered integrally with each other when the push button 16 is pushed down.
When released, the annular pistons 9 and 10 are raised by the force of the spring 12, and at this time, the liquid in the liquid storage container 1 is sucked up through the suction pipe 6 and enters the fixed cylinder 5, and then the push button 16 is pushed. When it is pushed down, the liquid in the fixed cylinder 5 is sprayed from the spray nozzle 17 through the pressure valve 19 from the inside of the flow path pipe 11 without flowing back by the check valve 18 (Actual Publication No. 3-7965).

As described above, in all the liquid atomizers including the conventional liquid atomizer shown in FIG. 5, the lid portion 4 is screwed to the mouth portion 2 of the liquid storage container 1 so that the lower end of the suction pipe 6 is made liquid. Fix the liquid in the liquid storage container 1 through the check valve 18 from the suction pipe 6 by pushing down the push button 16 or raising the push button 16 by the spring 12 so as to face the bottom of the storage container 1 near the bottom. The fixed cylinder 5 is temporarily moved into the fixed cylinder 5, and then the volume of the fixed cylinder 5 is narrowed by the downward movement of the small diameter annular piston 10 so that the fixed cylinder 5 is compressed and ejected from the fixed cylinder 5 through the spray nozzle 17. The liquid in the cylinder 5 cannot be blown out into the liquid storage container 1 through the suction pipe 6. Moreover, in the case of a portable liquid sprayer, since the liquid container 1 is small, the amount of the liquid in the liquid container 1 is used, and the remaining amount of the liquid container is reduced or disappears. After removing the fixed cylinder 5 and the suction pipe 6 of the sprayer main body 3 from the liquid storage container 1 by removing the lid 4 from the mouth 2 of the liquid storage container 1, another large container for liquid such as perfume is obtained. The liquid is taken out from the inside and poured into the liquid storage container 1. In this case, normally, a dropper as an inhaling / discharging device equipped as an accessory of the liquid sprayer is used to inject the liquid in the large liquid container into the liquid container 1.

[0005]

However, when replenishing the liquid in the liquid container 1, the liquid in the large container is introduced into the liquid container 1 by using a dropper as a suction / ejection device separately prepared. In the conventional method of injecting, since the dropper is separate from the portable liquid sprayer and is relatively small, there is a high risk of loss.
I often felt inconvenienced when I wanted to use it.

Therefore, the present invention is modified from the conventional system in which a dropper is separately provided as an accessory, and has a function of being able to discharge the liquid sucked through the suction pipe again through the suction pipe. It is intended to provide a liquid atomizer.

[0007]

In order to solve the above problems, the present invention forms a lid by engraving a screw and fixing a ring-shaped support plate on the inner surface of the lower end of a cylindrical case. , A liquid reservoir container that is supported by passing through a ring-shaped support plate of the lid portion, is expandable and contractible, and has a thin suction pipe attached to the lower end portion, and on the upper surface of the liquid reservoir container,
A liquid reservoir container pressing plate capable of sliding in the vertical direction on the inner surface of the cylindrical case is sandwiched to mount a pressure container that is expandable and contractible, and the pressure container and the liquid reservoir container are suction passages. In order to connect the internal flow path to the spray nozzle, the check valve is provided in the suction flow path, and the upper end of the push button body having the spray nozzle is attached to the pressing member arranged on the upper surface of the pressure vessel. The lower end of the hollow rod is attached so that the spray nozzle communicates with the inside of the pressure vessel, the cover for opening and closing the spray nozzle is rotatably attached to the push button body, and the ring-shaped support plate and the liquid reservoir container are pressed. A spring for biasing the pressing plate upwards is interposed between the pressing plate and the pressing plate, and a spring for biasing the hollow rod upwards is interposed between the hollow rod and the pressing member side. Spring up Configure the sprayer main body formed by weaker than the spring on the support plate, a structure in which the atomiser body and to be screwed into the mouth of the liquid container.

[0008]

[Function] When the push button is pushed down to contract the pressure vessel and the liquid reservoir, and then the push button is raised by the force of the spring to restore the liquid, the liquid in the liquid storage container is sucked up into the liquid storage container through the suction pipe. . Next, when the pushbutton is pressed down to perform an operation of contracting the pressure container, the liquid contained in the liquid reservoir container passes through the suction passage and enters the pressure container, and the liquid is compressed from the pressure container to move inside the hollow rod. It is ejected from the street spray nozzle. By rotating the cover of the push button to close the spray nozzle and removing the sprayer main body from the liquid storage container, the sprayer main body can be used as an inhalation discharge device.

6, a spring 37 having a smaller elasticity than the spring 27 is interposed between the overhanging portion 36 and the plate 33, and normally biases the hollow rod 34 so as to push it upward. When the hollow rod 34 is pushed down against the spring 37, the pressure vessel 29 is contracted via the pressing member 30 to increase the internal pressure, and when the hollow rod 34 is pushed down more strongly. ,
The bellows portion 25 of the liquid storage container 24 is contracted by the pressing member 30 via the pressure container 29 and the liquid storage container pressing plate 26, and at the same time, the overhanging portion 36 of the hollow rod 34, the pressing plate 33, the guide cylinder 28, the liquid The liquid reservoir container 24 can be contracted via the reservoir container pressing plate 26.

Further, regarding the liquid storage container 24 and the pressure container 29, the suction flow passage 38 provided at the bottom of the pressure container 29 penetrates through the plate 26 and the ceiling of the bellows part 25 to store the liquid storage container 2
4, a check valve 39 is provided in the suction flow path 38 to prevent the flow from the pressure container 29 to the liquid reservoir container 24 when the pressure container 29 is pressed and contracted. Then, the liquid in the pressure container 29 which has become high pressure is discharged through the flow path hole 35 in the hollow rod 34, and the upper end of the hollow rod 34 has a spray nozzle provided at one side position. A push button main body 41 having a flow passage 43 communicating with the flow passage hole 35 is attached to 42, and a decorative cover 44 having an opening 45 in a side wall is rotatably fitted to the outside of the push button main body 41. , A push button 40 which is adapted to rotate the cover 44 so that the spray nozzle 42 can be opened or shut off to the atmosphere in conformity with the opening 45 of the cover 44.
Then, the push button 40 can push down the inner side of the upper end portion of the tubular case 20.

Reference numeral 46 is a decorative cover attached to the outside of the tubular case 20, 47 is a partition plate, and 48 is the tubular case 20.
It is a cap fitted on the upper part of the above, and the partition plate 47 and the cap 48 are adapted to guide the vertical movement of the hollow rod 34 and to leak liquid. 49 is a ring-shaped support plate 23
Is a rubber packing which is arranged on the lower surface to seal the mouth 2 of the liquid storage container 1.

The support plate 23 and the liquid reservoir 24
The contact portion with is in a close contact state so that the liquid does not easily pass therethrough.

Now, when using the liquid sprayer of the present invention, the lid portion 21 of the sprayer body 3 is inserted so that the suction pipe 25a of the liquid storage container 24 is inserted into the liquid storage container 1 containing a liquid such as perfume. Is screwed onto the mouth portion 2 of the liquid container 1.

Next, when the liquid is ejected, the push button 40 is pushed down against the spring 37, or the push button 40 is returned by the force of the spring 37. By repeating the operation, the liquid in the liquid storage container 1 is stored in the liquid storage container 24. In this case, for example, even after the push button 40 is pushed down against the spring 37 to crush the pressure vessel 29, the push button 4 is further pushed against the spring 27.
0 is strongly pushed down to squeeze the liquid reservoir 24, and then the cover 44 of the push button 40 is rotated to the nozzle closing position to shut off the spray nozzle 42 of the push button body 41, and then the push button 40 is moved to the springs 27 and 37. If the force is restored by force, the liquid in the liquid storage container 1 is sucked up by the suction force when the crushed liquid storage container 24 is spread by the spring 27 into the liquid storage container 24 through the pipe 25a. Can be stored. By repeating this operation as necessary, a large amount of liquid can be sucked up and filled in the liquid reservoir 24.

When the liquid is stored in the liquid storage container 24, the cover 44 of the push button 40 is rotated to the nozzle open position so that the opening 45 is aligned with the spray nozzle 42, and then the push button 4 is pressed.
By pushing down 0 against the spring 37 with a short stroke, the liquid enters the pressure container 29 from the liquid reservoir container 24 through the suction flow passage 38, is compressed by the pressure container 29, and flows in the hollow rod 34. It will be sprayed from the spray nozzle 42 through the hole 35. At this time, the pressure vessel 29
Since the check valve 39 is provided in the middle of the suction flow path 38 that connects the liquid container 24 with the liquid reservoir 24, when the push button 40 is pushed down against the spring 37 and the pressure container 29 contracts, Since the liquid contained in the pressure container 29 does not flow back into the liquid reservoir 24 by the check valve 39, it is compressed into a high pressure and flows from the pressure container 29 through the central hole 31 of the pressing member 30 into the hollow rod. Flow path hole 35
It is made to flow into the inside and is instantaneously ejected from the spray nozzle 42. Next, when the finger is released from the push button 40, the hollow rod 34 is raised by the force of the spring 37, so that the upper surface side of the pressure vessel 29 is pulled upward together with the pressing member 30, and the pressure vessel 29 is automatically moved. Inflated. As a result, the liquid in the liquid storage container 24 is sucked up into the pressure container 29 through the suction passage 38, and accordingly, the fluid in the liquid storage container 1 is sucked up into the liquid storage container 24.

When the liquid atomizer of the present invention is not used,
The cover 44 of the push button 40 is rotated to the position where the nozzle is closed. This can eliminate the risk of liquid leakage from the spray nozzle 42.

Next, when the liquid is sprayed frequently and the liquid in the liquid container 1 is used up, the liquid stored in another liquid container is stored in the liquid sprayer of the present invention. It is made to inject into the container 1. In this case, after removing the sprayer main body 3 from the mouth portion 2 of the liquid container 1, the cover 44 of the push button 40 is rotated in the direction of closing the nozzle to the state shown in FIG. Liquid storage container 1 by inhaling liquid in another container using the main body 3
So that it can be injected inside.

That is, first, with the spray nozzle 42 of the push button 40 of the sprayer main body 3 removed from the liquid storage container 1 closed with the cover 44, the springs 37 and 27 are urged so that the liquid reservoir container 24 is crushed and contracted. Push button 4
0 is strongly pushed down with a large stroke, and the bellows portion 25 of the liquid storage container 24 is contracted between the liquid storage container pressing plate 26 and the support plate 23 as shown in FIG. In this state, the suction pipe 25a is submerged in the liquid in another container containing the liquid, and then the pushing-down force is gradually released so that the push button 40 is gradually returned. As a result, first, the plate 27 is pushed up by the spring 27 having a large elasticity, so that the liquid reservoir 24 is automatically expanded as shown in FIG. 2A, so that a suction action occurs and the liquid passes through the suction pipe 25a. And gradually sucked into the liquid reservoir 24. You may repeat the same operation as needed.

When the liquid is sucked into the liquid storage container 24 in this way, the suction pipe 25a is pulled out from the liquid and sucked into the inside from the opening 2 of the liquid storage container 1 of the liquid sprayer of the present invention. 25a is inserted, and the push button 40 is strongly pushed down from the state of FIG. 2 (a) to the state of FIG. 2 (b) to contract the liquid reservoir container 24 so that the liquid in the liquid reservoir container 24 is sucked up through the pipe 25a. Since it can be discharged, it can be injected into the liquid storage container 1.

In the present invention, since the atomizer main body 3 is adapted to be capable of both sucking and discharging the liquid by utilizing the suction pipe 25a, it can be used not only as the atomizer but also for storing the liquid. It can also be used as a device for injecting a liquid into the container 1, and a dropper as an accessory can be omitted.

Next, FIG. 3 shows another embodiment of the present invention. In FIG. 1, a spring 37 is interposed between the projecting portion 36 of the hollow rod 34 and the plate 33 to move the hollow rod 34 upward. In place of the structure for urging the pressure vessel 29, a spring having the same strength as the spring 37 is provided between the plate 50 fixed to the upper surface of the pressure vessel 29 and the liquid reservoir vessel pressing plate 26 and outside the pressure vessel 29. 51 is arranged to apply upward biasing force to the hollow rod 34 via the plate 50 and the pressing member 30.
