Liquid ejector

The technical field, Φ ^, relates to a liquid ejector provided to eject liquid or other liquid as it is or as a mist. Background technology

An aerosol-type liquid ejector using Freon gas is frequently used as an atomizer for continuously spraying liquid. This is because the inside of the container body is pressurized with gas and the head at the upper end of the valve pipe that is biased from the aerosol valve fixed in the container head is opened, the aerosol valve opens and the container opens. The structure is such that the liquid in the body is ejected from the ejection hole of the head through the valve and the valve pipe. However, an aerosol-type liquid ejector is very convenient because the valve is opened and the high-pressure liquid is ejected simply by pushing down the valve pipe of the aerosol valve through the head. If released into the air, it rises to an extremely high level and destroys the ozone layer. Therefore, there is a need to develop a manual liquid ejector that can eject continuously without using such chlorofluorocarbon gas.

By the way, generally speaking, a liquid accumulator-type atomizer such as that disclosed in Japanese Utility Model Laid-Open No. 63-185475 is often used as a liquid ejector. This accumulator-type sprayer applies ^ J to a tubular member having a / J cylindrical biston at its lower end from the inside of a small-diameter cylinder with a suction valve vertically suspended in the container body, and attaches it to the upper end of this member. The large-diameter cylindrical piston is fitted into a large-diameter cylinder suspended from the lower surface of the push-down head, and a valve body that rises from the upper end of the member and a valve hole that is drilled in the top wall of the large-diameter cylinder. When a discharge valve is formed and the press-down head is pressed down with respect to the container body, the high-pressure inside the large-diameter cylinder 9 lowers the tubular member against the urging and opens the discharge valve, thereby pushing down. Spraying from the sprayer that opens on the side of the head, and when the press-down head is released due to the elimination of the high pressure, the urging force increases the tubular member and the press-down head while the discharge valve is closed due to the urging. The suction valve opens and the container is inserted into both cylinders and into the tubular member. In which the inner liquid is provided as drawn.

Such a conventional pressure accumulating atomizer has a relatively short spraying time, requires a large number of operations of a press head, and is extremely troublesome, and can be replaced with the atomizer using the above-mentioned fluorocarbon gas. is not. In addition, the structure becomes complicated.

The present invention has been made under such a background, and has a long spray time and a high structure. It is an object to make the structure simple. Disclosure of the invention

The present invention provides a container body provided with a mouth and neck,

A cylinder hanging down from the mouth and neck into the container body,

A feed valve provided at the lower end of the cylinder;

SLb pipe from this valve to the bottom of the container body,

The upper end is engaged with the upper part of the cylinder, and is mounted on the outside or inside of the mouth and neck.

^: At the bottom of the wall, this fe ^ surrounds the wall from the outside ^: A guide tube with a certain distance from the wall,

A cylindrical piston that is vertically movably fitted into the cylinder;

^ From this piston:

A body attached to the top of this stem,

A sliding cylinder that hangs down from the connecting body and that fits vertically into the space between the wall 17 and the guide cylinder;

A head having an ejection hole provided above the stem and communicating with the inside of the stem;

And a discharge valve provided at an upper end of the stem.

When the head is lifted, when the head and the piston are lifted, the inside of the cylinder is depressurized, the suction valve is opened, and the liquid in the container body is sucked into the cylinder. When the head is depressed from this state, the valve closes only when the piston descends, the discharge valve opens, and the liquid in the cylinder is ejected from the ejection hole until the cylindrical piston reaches the limit.

And since the said sliding cylinder is guided by a guide cylinder, even if the length force of a stem becomes long, it can operate up and down stably.

Further, a spring for raising the piston can be provided.

Here, it is preferable to use, as the discharge valve, an aerosol type valve having a valve pipe connected to the head and opening when the head is pushed down to push down the stem and the biston.

The aerosol type valve has a valve body that is open at the top and bottom, an elastic body having a first through hole that closes the upper surface of the valve body, and a second through hole ′ that matches the first through hole and is elastic. When the body is wrapped together with the valve body, the lower end is closed and the upper end is open and the head is connected to the upper end. A second through-hole of the jacket and a first through-hole of the elastic body. And a spring having a lower end inserted into the valve body and an elastic body fitted into the annular recess, and a spring for urging the valve pipe upward. be able to.

It is more preferable that the force ^s , which can be formed of a metal plate such as aluminum, be made of synthetic resin and be fitted over the upper part of the valve body.

Next, the following configuration is mentioned as another configuration for achieving the above object. This is a container body with the mouth and neck standing upright,

An outer cylinder portion having an upper end portion detachably attached to the mouth and neck portion and hanging down into the container body; and an inward flange-like bottom wall attached to a lower end of the outer cylinder portion,

A discharge valve provided at the upper end of the cylinder;

A liquid ejecting apparatus includes a head having an ejection hole communicating with the inside of the cylinder via the discharge valve, and a spring for urging the cylinder in a downward direction with respect to the inner cylinder portion.

Also in this case, the aerosol type as described above can be used as the discharge valve.

Then, when the head is pulled up with respect to the container main body, the cylinder rises, the inside thereof becomes negative pressure, and the liquid in the container main body flows into the cylinder through the suction valve. Next, when the head is released, the cylinder is urged downward by a spring, so that the liquid in the cylinder is subjected to calo pressure. When the push-down head 37 is pushed down from this state, the discharge valve opens, and the liquid in the cylinder is ejected from the ejection hole. When the head is released, the discharge valve is closed and the spraying is stopped. However, if the head is kept pressed, the spraying is continued until the operating member 20 reaches the lower limit as shown in the figure.

Since the sliding cylinder is guided by the guide cylinder, it is possible to stably operate up and down even if the length ^{s of the} stem is increased.

Only when the inside of the main body 1 is under negative pressure, the outside air is blocked so that it can flow in. On the other hand, a wall 17 is joined to the outer surface of the mouth and neck 4 of the container body 1. The upright wall 17 has an inward flange 16 at an upper end, and the inward flange 16 sandwiches the outward flange 6 with the upper end surface of the mouth and neck portion 4 via the packing 11, whereby the cylinder 9 is fixed.

A guide cylinder 20 is erected from the lower end of the wall 7 via a gap holding plate 18. The guide tube 20 surrounds the upright wall 17 from the outside and stands up at a certain interval from the upright wall # 7.

Further, a cylindrical piston 26 is fitted in the cylinder 9 so as to be vertically movable.

This embodiment also has the same effect as the above difficult example.

[Example 3]

As shown in FIG. 4, this embodiment has a configuration similar to that of the first embodiment. However, in Example 1, ^ 5: the wall 17 was screwed to the outside of the mouth and neck 4, whereas in this embodiment, ^: the wall 7 was arranged inside the mouth and neck 4. Further, in the first embodiment, the guide tube 20 which is connected to the lower end of the wall 17 and which surrounds the ^: wall 17 from the outside and has a fixed distance ^ from the wall 17 is also provided in the first embodiment. In this embodiment, it is located inside the mouth and neck 4, whereas it is located outside the part 4.

A screw tube is provided which is connected to the upper end of the guide tube 20 and hangs therefrom. The screw tube is screwed to the mouth-neck portion 4.

The upper part of the stem 27 is expanded and the aerosol pulp 45 with the pushing head is pushed down into the upper part. FIG. 5 shows an example of this valve. A valve body 66 having an outward flange 65 and an elastic body 67 having a first through hole for closing the upper surface thereof are wrapped in a ^ 68 with a second through hole. In addition to being integrally connected, an annular concave portion 69 is provided in the middle, and a valve pipe 71 having a closed lower end surface in which a valve hole 70 is formed in the annular concave portion of the bracket is passed through the first through hole and the second through hole. An elastic body is fitted into the annular recess, the valve hole 70 is closed by the inner wall surface of the through hole of the elastic body 67, and the valve pipe 71 is closed. The valve is urged upward by a spring 72, and the valve hole 70 and the elastic body 67 form a discharge valve. When the head 40 with the ejection hole 43 is fitted to the upper end of the valve pipe 71, and the head 40 is pushed down by being urged, the first pipe 11 の of the elastic body 67 is lowered by the lowering of the valve pipe 71. The valve hole 70 is opened by bending in the direction, and when the valve pipe 71 rises due to the interruption of pushing down, the elastic body 67 is also elastically moved to the position shown in the drawing to close the valve hole 70.

In the case of an aerosol-type liquid ejector, the upper end of the outflow pipe is fitted into the cylindrical portion 66a that hangs down from the inner peripheral edge of the inward flange-shaped bottom wall of the valve body 66, and the outflow pipe is suspended into the container body 1. In the case of this project, the pipe is unnecessary.

A connecting body 28 having a cylindrical shape and projecting outward is fitted to the upper end of the valve 45 or the stem 27, and a sliding cylinder 29 is hung on the connecting body 28. The guide tube 20 is vertically movably fitted.

The aerosol-type valve member 45 with the structure closes the valve immediately, so that there is no dripping and liquid ejection can be stopped.

The same parts as in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

(Example 4)

As shown in FIG. 6, the fourth embodiment has the same aerosol valve as the first embodiment except that the wall 17 is provided outside the mouth and neck 4 and screwed to the mouth and neck 4. This is similar to the third embodiment.

However, it differs from Examples 1 and 3 in the following points.

First, in the fourth embodiment, the upright wall 7 has an inward flange 16 at the upper end, and the outward flange 6 is formed between the upright wall 16 and the upper end surface of the mouth and neck 4 via the packing 11. Thus, the cylinder 9 is fixed. In this respect, this embodiment is the same as the first embodiment. However, in this embodiment, the locking cylinder 80 further extends from the inner periphery の of the inward flange 16, rides over the short cylinder 12 above the cylinder 9, and hangs down in the cylinder 9. Are integrally provided. The locking cylinder 80 is adapted to be disengaged from the lower end force s of the piston 26, and determines the upper limit of the stroke of the piston 26. Further, since the locking cylinder 80 is integrated with the wall 17: the second guide cylinder 35 provided in the first embodiment is provided. Is no longer needed.

An outward flange-like connecting body 28 is attached to the upper end of the stem 27, and a sliding cylinder 29 is provided so as to hang down from the outer periphery of the connecting body 28, as in the first and third embodiments. The stem 7, the connecting body 28, and the sliding cylinder 29 are different from the first and third embodiments in that they are formed from synthetic resin. The engaging body 81 is provided with an engaging hole 81 in the test body 28. The aerosol-type pulp 45 is fixed to the upper surface of the stem 27 by the cylindrical fixing period 2 in which the claw portion at the lower end is pulled on the edge of the hole 81 and is mounted on the upper surface of the stem 27 from above.

In this way, the number of parts can be reduced by reducing the number of parts and the manufacturing cost can be reduced.

Next, as shown in FIG. 7, the aerosol type valve 45 used in the fourth embodiment has a cylindrical valve body 66 having an upper body larger in diameter than the lower body, and a first through-hole elastic member for closing the upper surface thereof. The body 67, the elastic body 67 with the first through-hole, and the cylindrical valve body are wrapped with a synthetic resin 68 with a second through-hole and integrally connected. That is, the synthetic resin sheet 68 has a structure in which a side wall 68b is vertically provided around a top plate 68a having a second through hole at the center, and a groove is provided inside the side wall 68b. The protrusion provided on the outer periphery of the upper part of the cylindrical valve body 66 is fitted to the cylindrical valve body 66 by fitting. Then, a valve pipe 71 having an annular recess in the middle and having a valve hole 70 formed in the annular recess and having a closed lower end face is connected to a second through hole made of the synthetic resin 68 and a first through hole of the elastic body 67. The valve hole 70 is closed by the inner wall surface of the first through-hole of the elastic body 67 by inserting the elastic body 67 into the annular concave portion, and further provided in the cylindrical valve body 66. A spring 72 urges the valve pipe 71 upward. Thereby, the valve hole 70 and the elastic body 67 form a discharge valve. Then, when the head 40 with the jet ¾23 is put on the upper end of the valve pipe 71 and the head 40 is pressed down against the urging, the first pipe of the elastic body 67 is formed by the lowering of the valve pipe 71. The valve hole 70 is opened when the 緣 portion is bent downward, and when the valve pipe 71 rises due to the interruption of the pushing down, the elastic body 67 is also elastically moved to the position shown in the drawing to close the valve hole 70.

In this example, unlike the valve 45 of the third embodiment, a metal resin was not used, and a synthetic resin jacket was used. Therefore, compared to the case of the ^third embodiment in which the metal jacket was attached with force, a cylindrical valve body was used. The fitting of ^ MS68 to 66 became extremely easy.

In the fourth embodiment, the normal packing 11 without the thin tube portion 15 is used instead of the packing with the thin tube portion 15 in the first embodiment. Other structures are the same as those of the first and third embodiments, and thus the same reference numerals are given and the description thereof will be omitted.

As shown in FIG. 8, the piston 26 is divided into a cylinder 26a connected to the stem 27 and a piston body 26b, and the piston body 26b is sandwiched between the cylinder 26a and the stem 27. You may make it. If this is done, the cylinder diameter will be large. To perform exchange force ^s easily of Bisuton body 26b is. (Example 5)

In the fifth embodiment, as shown in FIG. 9, a spring 90 is provided between the upright wall 17 of the fourth embodiment and the connector, and the headstone 40 and the stem 27 are always in the ascending position together with the stem 27. It is biased by a spring 90. For this reason, when not in use, the through-hole 10 for preventing negative pressure in the container body 1 is closed with biston: ^ Even if there is no thin cylindrical portion 15, liquid does not leak from the through-hole 10.

Note that the spring 90 may be stretched between the locking cylinder 80 and the biston 26, as shown by the one-dot chain line in FIG.

As described above, if the spring 26 is urged by the spring 90 so that the piston 26 together with the head 40 and the stem 27 are always at the ascending position, it is necessary to pull up the head 40 and the like in the case of repeated spraying operations. When such a spring 90 is provided, a device for locking the head 40 or the like in a depressed state at the time of transporting a container may be provided. A projection is provided on the outer surface of the sliding cylinder 29, a vertical groove for inserting the projection of the sliding cylinder on the inner surface of the guide cylinder 20 and a horizontal groove connected to the lower end of the vertical groove are provided. It is good to shift from the vertical groove to the horizontal groove to lock the head 40 ゃ stem 27.

(Example 6)

In this embodiment, as shown in FIG. 10, the aerosol type valve 45 of the fifth embodiment is incorporated in the stem 27, and the cylindrical valve body 66 forms a part of the stem 27. An integrated synthetic resin ^ ^ 68 is fitted on the upper surface of the stem 27, an elastic body 67 with a first through hole is mounted on the upper portion of the stem 27, and a valve pipe 71 with a closed lower end face with a valve hole 70 is formed. The second through-hole of the synthetic resin 68 and the first through-hole of the elastic body 67 are inserted through the second through-hole, and the elastic body 67 is fitted into the annular recess so as to be fitted on the inner wall surface of the first through-hole of the elastic body 67. Further, the valve hole 70 was closed, and the valve pipe 71 was urged upward by a spring 72 engaged with a step provided in the stem 27. The synthetic resin 68 is integrated with the cylindrical fixed cylinder 82 which is inserted and locked by a tip force ^s into a locking hole 81 provided in the coupling body 28, so that the number of parts is small. Less.

By doing so, the number of parts can be reduced, mass production can be reduced, and costs can be reduced. .

Force [It is only necessary to communicate the inside of the pressure chamber 125. In addition to the illustrated example, the valve 45 is provided so as not to bend the elastic body 67, and the valve hole 71 is opened from the inner wall surface of the through hole of the elastic body 67 by opening the valve pipe 71 in the valve body 66 when the valve pipe 71 is lowered. When the spray head 43 is sprayed and the press-down head 40 is released, the spring 72 pushes up the valve pipe 71 again to close the valve hole 70 with the inner wall surface of the through hole of the elastic body 67. Some have done so.

The cylinder 9 is urged downward with respect to the inner cylinder by a spring. In the illustrated example, the lower end of the spring 100 loosely fitted to the outer surface of the inner cylindrical portion 9 of the main cylindrical member is pressed against the upper surface of the inward flange 126 and the upper end of the spring is pressed against the lower surface of the large outer diameter portion of the inner cylindrical portion 9. I have.

Since the present invention has been described, the liquid SU can be introduced into the pressurizing chamber 125 simply by pulling up the cylinder 9 with respect to the outer cylinder 107 and the inner cylinder 109. By pressing down 40, it is possible to continue spraying until the liquid in the pressurizing chamber 125 is exhausted, and a suction valve 7 is provided in the upper part of the inner cylinder part 109, and the cylinder 9 is provided on the outer surface of the inner cylinder part 109. The cylinder 9 above the inner cylinder portion 109 is fitted with a watertight chamber 125, and the discharge valve 45 having the above configuration is provided above the cylinder 9.The compression ratio of the pressurizing chamber is determined by the above-described conventional pressure accumulating method. It can be significantly increased compared to a nebulizer.
