Description

Detailed Description of the Invention [Objective of the Invention] (Industrial Application Field) This invention is directed to, for example, sealing a spray agent and a pressurizing agent in a spray cylinder, and using the spray agent in the cylinder as a pressurizing agent. The present invention relates to a spray device such as a sprayer that sprays water from a spray nozzle using gas pressure.

(Prior art) In general, sprays for painting, insecticide, and hair styling use a spray agent such as paint, insecticide, or hair styling product to be sprayed using the power of vaporized gas from a pressurizing agent. . That is, as shown in FIG. 5, a spray agent and a pressurizing agent are sealed in a cylinder 51, and the interior thereof includes a layer A of the spray agent, a layer B1 of the pressurizing agent, and a layer where the pressurizing agent is vaporized. It is divided into three layers: layer C of pressurized gas. Then, when the head of the nozzle part 52 is pushed down with a finger or the like, the spray agent is guided to the nozzle part 52 through the conduit 53 by the pressure of the pressurized gas.
The liquid is ejected from the nozzle tip of this nozzle portion 52.

By the way, the above-mentioned spray agent is generally heavier than the pressurizing agent, and accumulates at the bottom of the cylinder 51. Therefore, in the spray having the above configuration, the conduit 53 made of, for example, hard wood (a non-flexible member) has its tip (
The spray agent inlet) is fixedly attached to one place at the bottom of the cylinder 51 as shown in the figure. Therefore, in order to use up the above-mentioned spray agent before the pressurizing agent runs out, its usability is extremely limited. In other words, the sprayer must be used in such a position that the layer A of the spray agent is located at the spray agent intake opening of the conduit 53. For example, if the nozzle section 52 is used facing downward, the pressurizing agent will be absorbed more than the spray agent. There was a problem that all the spray agent could not be used up because it ran out first.

(Issue 8 to be solved by the invention) This invention was made to solve the drawbacks that the usability is very limited and, depending on how it is used, unused amount of spray agent may remain in the cylinder. To provide a spray device that is easy to use and can completely use up a spray agent before the pressurizing agent runs out.

[Structure of the Invention] (Means for Solving the Problem) The spray device of the present invention includes a spray cylinder in which a spray agent and a pressurizing agent are sealed, and a spray cylinder that sprays the spray agent in the spray cylinder. and a spray conduit for guiding the spray in the cylinder to the spray nozzle, the spray conduit having a spray inlet always at the deepest point of the spray in the spray cylinder. It is configured to be made of a flexible member so as to be positioned in the same position.

(Function) In this invention, a spray conduit that guides the spray in the cylinder to the spray nozzle is formed of a flexible member, so that the spray inlet of the spray conduit is always connected to the spray in the spray cylinder. It is located at the deepest part of the agent.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 schematically shows a sprayer as an example of a spraying device according to the present invention. As shown in FIG. 1(a), this spray is made of 12 and a conduit 13 that guides the spray agent in the cylinder 11.

A spray agent and a pressurizing agent are sealed in the cylinder 11, and the interior thereof includes a layer A of the spray agent, a layer B1 of the pressurizing agent, and a layer C of pressurized gas obtained by vaporizing the pressurizing agent. Divided into 3 layers. Generally, the above-mentioned spray agent is heavier than the pressurizing agent, etc., so regardless of the position in which the sprayer is used, from the top to the top of the cylinder 11, the following layers are formed: pressurized gas layer C1, pressurizing agent layer B1, and spray agent layer A. .

The nozzle portion 12 is fixedly attached to the tip position of the cylinder 11, for example, the head portion 12a of the nozzle portion 12.
When pressed down with a finger or the like, a valve (not shown) in the attachment member 12c is opened by the connecting member 12b, so that the conduit 13 and the spray nozzle 12d are in a penetrating state.

The conduit 13 is formed of a flexible member (beam material) such as fluororubber or fluororesin. That is, the conduit 13 has one end attached to the member 12. c and the other end (
so that the spray agent intake) side is always located at the deepest part of the spray layer A, regardless of the posture when using the sprayer.
A tube made of a flexible member is used. In this case, the flexible member may be a fluororubber such as Pytol (trade name) or Florel (trade name), which has excellent chemical resistance and heat resistance, or Teflon, Polyflon, Teflon, Neoflon, or Tefzen. Fluororesins such as , Aflon cop, Daiflon, and Kynar KF polymer (all trade names) are used, and the most suitable member from among the beam materials mentioned above is used depending on the type of spray agent.

Furthermore, a chain-shaped insert 14, for example, is inserted into the interior of the conduit 13 in order to prevent the conduit 13 from being blocked by the pressure of pressurized gas. That is, FIG. 1(b)
1(a) is a cross-sectional view of the circular frame portion of the conduit 13 in the longitudinal direction of the conduit 13. A chain-shaped insert 14 inserted into the conduit 13 allows a passageway to be formed inside the conduit 13. I'm trying to secure space. In this case, the insert 14 is made of a member that will not be corroded or dissolved by the spraying agent, for example.

When the head 12a of the nozzle section 12 is pushed down with a finger or the like, the spray agent is guided to the nozzle section 12 via the conduit 13 by the pressure of the pressurized gas and is sprayed from the tip of the spray nozzle 12d. In this case, the conduit 13 is such that the spray inlet is always located at the deepest part of the spray layer A due to the insert 14 and its own weight. This makes it possible to reliably guide the spray agent to the nozzle section 12 even when the sprayer is used with the nozzle section 12 facing downward as shown in the figure. Therefore, all the spray agent can be efficiently used up before the pressurizing agent runs out, without being subject to restrictions on the posture when using the spray.

Further, due to the effect of the chain insert 14, the spray agent is actively mixed while being guided through the conduit 13 to the nozzle portion 12, and a good mixed state of the drug is obtained.

As mentioned above, there is no possibility that the pressurizing agent will run out first and that unused portions of the propellant will remain in the cylinder. Therefore, one spray can be used effectively, and there is no need to use more than the necessary number of sprays.

Further, since no wasted pressurizing agent is used, only a small amount of pressurizing agent is required. Therefore, the amount of pressurizing agent sealed in the cylinder can be reduced, and conversely, the amount of spraying agent can be increased.

Furthermore, when disposing of used sprays,
For example, it is possible to prevent a fire accident caused by a flammable spray agent during transportation or when puncturing a cylinder.

In the above embodiment, the spray inlet of the conduit 13 is moved to the deepest part of the spray layer A by the weight of the conduit 13 and the insert 14, but the present invention is not limited to this. A weight may be attached near the agent intake port. In this case, the weight of the weight makes it possible to move the spray agent intake of the conduit 13 efficiently.

Further, FIGS. 2, 3, and 4 all show other embodiments of the present invention.

That is, FIG. 2 shows a conduit 15 formed of a flexible member at the tip of a short conduit 15a made of hardwood.
b is attached, and this attachment is done by fixing the part with a band 15c.

In this case, an insert 14 for preventing blockage is inserted into the inside of the conduit 15b, and the weight of the insert 14 and the conduit 15b allows the spray agent intake port of the conduit 15b to move freely according to the usage position of the sprayer. This ensures that the spray agent can be located at the deepest part of the spray layer A.

Further, as shown in FIG. 3, the cross-sectional shape of the passage 16a of the conduit 16 formed of a flexible member is made to have a shape that will not be blocked by the pressure of pressurized gas or the like. Also good.

In this case, by attaching the dust 17 to the tip (spray agent receiving port), the weight of this dust 17 ensures that the spray agent intake port is located at the deepest part of the spray layer A. .

Furthermore, FIG. 4 shows that the conduit 18 is
This example shows a case in which the pipe is formed into a bellows shape, and by attaching a weight 19 to the tip (spray agent receiving port), it is strong against the force that attempts to block the conduit 18, and it can be adjusted to the position in which the sprayer is used. The spray agent intake port of the conduit 18 can be reliably located at the deepest part of the spray layer A.

It goes without saying that various other modifications can be made without departing from the gist of the invention.

[Effects of the Invention] As described in detail above, according to the present invention, it is possible to provide a spraying device that is easy to use and can completely use up the spraying agent before the pressurizing agent runs out.
