Description

[Detailed Description of the Invention] Purpose of the Invention [Industrial Application Field] The present invention relates to an aerosol-type spraying device for spraying a chemical solution such as a detergent or an insecticide.

[Conventional technology]

In general, an injection device is configured to press an injection button provided on the top of an aerosol body to eject the internal chemical liquid from an injection nozzle. Since the chemical liquid becomes a mist and scatters in a radial pattern, some of it is wasted, polluting the indoor air, and getting on your hands and skin. As a means to improve this, for example, Publication No. 132,864/1986 discloses a method in which a rectangular hood is provided to surround the nozzle opening of the injection nozzle so as to regulate the direction of mist scattering. . Such a hood is effective when spraying detergents or insecticides or when the application surface is a closed surface such as a glass window, wall, tatami mat, or carpet. However, on transparent surfaces such as screen doors, when a hood is brought into contact with the mesh surface and foamed detergent is sprayed, much of the detergent escapes through the mesh, making it difficult to apply the appropriate amount of foamed detergent to both the inside and outside of the screen without wasting any waste. It is.

[Problem that the invention attempts to solve]

An object of the present invention is to solve the above-mentioned problems and provide a spraying device that can spray and apply chemical solutions such as detergents even to transparent surfaces such as screen doors without waste.

Structure of the invention [Means for solving the problem] To explain with reference to the drawings, the injection device of the invention, as shown in Figs. In an injection device in which a hood 4 surrounding a nozzle opening 3 is provided on an injection nozzle 2 of an aerosol body 1 filled with a solution S consisting of It is characterized in that the nozzle opening 3 is opened along a side edge 41 in the longitudinal direction.

The nozzle port 3 is located above the inside of the hood 4 and opens downward substantially parallel to the side edge of the hood 3. As shown in FIG. 3, this nozzle opening 3 is
It is formed integrally with a junction head 32 with a collar 31 in between, and the head 32 is fixed with an adhesive or the like so as to protrude from the back surface of the hood 4. A fitting hole 33 is provided on the side surface of the junction head 32, and an L-shaped connecting tube 35 having a split pin-shaped fitting portion 34 at one end is rotatably fitted into the hole 33. The other end of the pipe 35 is detachably connected to the injection nozzle 2 connected to the injection button 6.

In this way, the injection nozzle 2 of the aerosol body 1
The nozzle port 3 has an L-shaped connecting pipe 35 and a junction head 32, so that its conduction path is connected to the L-shaped nozzle in two places.
It is bent into the shape of a letter. The notch 5 is located at the side edges 4 on both sides.
1, but one may be omitted.

[Effect]

In the injection device of the present invention, the aerosol body 1
For example, a case will be described in which a screen door is cleaned by filling a solution consisting of a normal surfactant as a foam detergent and liquefied gas (LPG) as a propellant. As shown in Fig. 5, when you hold the body of the aerosol body 1 and press the injection button 6 while lightly touching the periphery of the hood 4 with the screen surface of the screen door D, the solution will be ejected from the nozzle opening 3 and the liquefied gas will be released. Detergent foam B is foamed due to the action of detergent foam B and accumulates inside the hood 4.

This bubble B is decelerated because the nozzle port 3 is almost parallel to the mesh surface and the conduit path from the injection nozzle 2 to the nozzle port 3 is bent, so that it escapes from the mesh at the same time as it is ejected. Never happened.

In this way, when the inside of the hood 4 is filled with bubbles B, some of the bubbles leak out laterally from the notches 5 on both sides due to the pressure of the bubbles B that are continuously ejected, and some of them leak through the mesh. Both the inside and outside of the net are covered with an appropriate amount of detergent. In this state, by sliding the hood 4 along the screen surface, the entire screen door D can be cleaned evenly and quickly without wasting detergent. Note that the foam B can be wiped off from both sides with a sponge or the like, without adsorbing and removing oil and dirt adhering to the mesh.

The hood 4 may cause detergent to scatter around,
Needless to say, there is no risk of it getting on your hands, but since the hood 4 rotates at the fitting part 34 of the connecting tube 35, the aerosol main body 1 and the hood 4 can be connected together as shown in FIGS. 2 and 5. By tilting it up and down, you can use it in a comfortable position. Moreover, by pulling out the connecting pipe 35 from the injection nozzle 2 and removing the hood 4, it can be used in exactly the same way as in a normal case.

〔Example〕

Figures 1 to 3 show representative examples of the present invention. In the figure, 7 is a double chevron-shaped one-touch cap, and in the center of the cap 7 is a flexible button for operating and protecting the injection button 6. A lever 8 is provided. In FIG. 5, the cap 7 is omitted to show the operating state.

FIG. 4 shows another embodiment of the present invention, in which the connecting pipe 3
5' is a straight pipe, and this and juncture head 3
2, an L-shaped connecting tube 36 having fitting portions 34 at both ends is fitted. In this case, the hood 4 can be tilted either vertically or horizontally with respect to the aerosol body 1, making it easier to use.

The above example has been described in which the nozzle port 3 of the injection nozzle is directed upward inside the hood 4.
The nozzle port may be located in the center or below, and if the nozzle port is located in the center, the nozzle port may be directed both upward and downward, and if the nozzle port 3 is located above and below the inside of the hood 4, the main body of the nozzle port should be directed downward and upward, respectively. , a portion may be opened on the opposite side. Moreover, in the case of the lower part, it is sufficient to open upward. food 4
The shape may be circular or rectangular, but it is preferably rectangular or oval in order to quickly check the ejection status of the chemical solution and avoid waste. Furthermore, the notch 5 provided in the hood 4 is not limited to the central part of the side edge 41 as shown in FIGS. 1 and 2;
It is preferable to provide a round shape over the entire side edge 41. Furthermore, the injection nozzle 2 and the nozzle port 3
In other words, by omitting the junction head 32 and the connecting pipe 35, the hood 4 may be directly connected and fixed. In this case as well, the nozzle opening 3 is connected to the injection nozzle 2.
Similarly to the above, it is bent into an L-shape, N-shape, S-shape, etc. to slow down the jetting of the chemical solution and to spray the chemical solution (foam) approximately horizontally onto the application surface such as a screen door. .

Effects of the invention The injection device of the invention has a notch in the longitudinal side edge of the hood surrounding the nozzle opening of the injection nozzle, and the nozzle opening is opened along the longitudinal side edge, so that the chemical solution can be applied to the application surface. Since the foam can be sprayed in a horizontal direction, it is especially suitable for spraying and cleaning transparent surfaces such as screen doors, eliminating scattering and waste of detergent, and preventing it from getting on hands, etc. There is no risk of contamination. In addition, the hood can be rotated vertically, horizontally, etc. with respect to the injection nozzle, allowing it to be used in a comfortable posture.The hood can also be detachably connected to the injection nozzle, allowing it to be used with a normal injection device. Similar usage is possible.
