Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an aerosol sprayer having two types of nozzles having different jetting methods.

[Prior art] When spraying an insecticide for the purpose of exterminating insects such as cockroaches, in addition to the normal spraying operation of spraying from the ejection port provided on the push button, a refrigerator and a wall (or floor), a water store, When spraying the insecticide in a narrow space such as a closet or a gap between a wall plate and a wall, it is necessary to perform a spraying operation using a long nozzle such as inserting a long nozzle into the narrow space and spraying. is there.

For this purpose, in order to avoid the inconvenience of replacing a normal push button and a push button with a long nozzle one by one in use, an injection nozzle provided with two kinds of nozzles as shown in Japanese Utility Model Publication No. 61-43557. Has been devised.

This conventional nozzle device will be described with reference to FIG.
FIG. 9 is a side sectional view of the state in which the long nozzle is rotated downwards, FIG. 9 is a front view of an essential portion thereof, and FIG. 10 is a side sectional view of the essential portion showing a state in which the long nozzle is horizontally projected. Therefore, the push button 1 is fitted into the nozzle stem b of the aerosol container a, and the injection short cylinder 15 is integrally provided on the side of the push button, and the joint 4 is pivoted by the pivot shaft 48 at the tip thereof. It is freely inserted, and the long nozzle 5 is attached to the joint 4. Thus, the base portion 44 of the joint 4 is provided with a passage 45, a nozzle 46 at the tip thereof, and a passage 47 which is orthogonal to the passage 45 with its position offset and communicates with the long nozzle 5. As shown in FIG. 8, since the passages 45 and 47 are provided in the joint 4 at different positions, the injection port 46 is removed from the center of the base portion 44.

The use state will be described. As shown in FIG. 8, if the long nozzle 5 is rotated downward and the push button 1 is pushed, the container a
The liquid in the nozzle stem b is passed through the passage 11 in the push button 1, the passages 16 and 17 in the short injection cylinder 15, the passage 45 in the base 44 of the joint 4, and is sprayed from the injection port 46.

Further, as shown in FIG. 10, if the long nozzle 5 is horizontally projected and ejected, then the liquid passes through the passages 16 and 17 and then the passage 47 in the base portion 44 to the passage 51 in the long nozzle 5. After that, it is sprayed from the nozzle 52 at the tip.

[Problems to be solved]

In the above-mentioned conventional injection device, the injection port 46 is generally called a straight injection port, but in this straight injection port, a prescription with a large amount of injection gas results in a mist, but when the injection gas decreases, the spray particles become large and directly. It is jetted like a water gun. This also applies to water-based stock solutions, especially cleaners (such as glass or kitchen).

However, recently, there has been a problem of preventing the damage of CFCs, and it is necessary to reduce the amount of injected gas. Therefore, when the injection gas amount is reduced, or when it is desired to use it for the water-based prescription as described above, it is impossible to spray with a straight nozzle such as the nozzle 46. It is necessary to install it in a place. However, in the conventional injection device,
Since the passages 45 and 47 are staggered and orthogonal to each other,
As shown in the figure, the nozzle hole 46 is not located in the center of the base 44 when viewed from the front of the sprayer, so in order to mount the nozzle hole of another component
It is necessary to make the injection hole part large, and there is a problem that the whole becomes large.

Furthermore, the conventional aerosol sprayer has a problem that the cap must be covered when not in use and removed one by one before use.

[Means for solving the problem]

In this invention, in order to eliminate the above-mentioned drawbacks, in an aerosol sprayer in which a joint in which a nozzle member and a long nozzle are fitted is connected to a button body, the joint includes a pore communicating with the long nozzle and a pore thereof. In a direction perpendicular to the groove, and a groove communicating with the groove, bypassing the pores communicating with the long nozzle, and communicating with the nozzle member fitted so that the nozzle is located at the center of the joint. Further, the joint is covered with a case body, and the cover body is fitted into the front slit of the cap so that the cap does not have to be removed for use. (EN) An aerosol sprayer which can slide up and down in the slit together with the main body.

[Action]

Since the present invention has the above-mentioned structure, the groove communicating with the nozzle member passes through the hole that bypasses the long nozzle, so that the nozzle of the nozzle body in the nozzle member should come to the center of the joint. Therefore, it is possible to prevent the entire size from becoming large even when a separate injection port is attached.

Further, since the joint is covered with the casing so that the inside of the front slit of the cap can be slid up and down together with the button body, it is not necessary to remove the cap one by one in use.
