Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an airbrush.

[0002]

2. Description of the Related Art A conventional airbrush is disclosed, for example, in Japanese Utility Model Registration No. 3048488 (prior art 1). In the prior art 1, the paint container is attached to the airbrush main body, and the airbrush main body is “inside”.
In this method, the paint is sucked by air to eject the atomized paint from the nozzle at the tip of the airbrush. As described above, when the paint is sucked inside the airbrush main body, the internal structure of the main body for the suction is complicated, resulting in an increase in cost.

On the other hand, in order to simplify the structure, there is a method in which the paint in a paint container is sucked “outside” an airbrush main body (prior art 2). In the prior art 2, a paint supply nozzle extending upward from a paint container is provided, and air ejected from an air nozzle at the tip of an airbrush is ejected toward the paint supply nozzle, and paint is sucked by the ejected air. And sprays the atomized paint on the object to be coated. An airbrush that sucks paint outside the airbrush but uses a writing instrument instead of a paint container is also known. For example,
Japanese Patent No. 57447 discloses an airbrush that sprays air onto a pen tip of a writing instrument such as a pen installed downward to suck ink and spray atomized paint (prior art 3).

[0004]

The prior art 2 has a simplified structure compared to the prior art 1, but the paint container is installed below the airbrush body and the paint supply nozzle is directed upward. The supply of the paint is performed such that the paint is sucked up. Therefore, a relatively high pressure is required for the air for sucking the paint. Further, in the prior art 3, since the paint of the writing implement is used, the color is limited to that which is commercially available as the writing implement, and is generally commercially available when compared with the kind of the color which is commercially available only with the paint. The types of writing instruments are very limited. Therefore, an airbrush using only a writing instrument lacks versatility. Further, the writing implement is limited to the use of painting only, and cannot be used for spraying a liquid for forming a film on the painting.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and is directed to an airbrush of a type using a paint container which is more versatile than an airbrush of a type using a writing instrument. The purpose is to solve the problems pointed out in 2. Another object of the present invention is to provide an airbrush that can use both a paint container and a writing implement in order to enjoy the simplicity of using a writing implement.

[0006]

In order to achieve the above object, the present invention employs the following technical means. That is, the feature of the airbrush according to the present invention is, in the airbrush body having a gas ejection nozzle, and in the airbrush provided with a paint container in the airbrush body, the paint container,
It has a supply port for supplying paint to the inside of the container, and a paint nozzle from which paint is sucked out of the container by jetting of gas,
The paint nozzle is located close to the ejection nozzle so that gas from the ejection nozzle is ejected toward the paint nozzle, and is arranged in a downward direction.

In the present invention, instead of a writing instrument, a paint container having a supply port for supplying paint into the container is used, so that various paints can be put in the paint container, and a writing instrument such as a pen can be used. Various paintings are possible in comparison. Further, if a coating liquid is put into a paint container, it can be used for forming a coating, that is, a top coat, in addition to coating. Since the paint nozzle close to the ejection nozzle is arranged in a downward state, the paint can be sucked even with a low-pressure gas as compared with a conventional upward nozzle. The “downward direction” of the paint nozzle includes an obliquely downward direction or a downward direction. It is preferable to use compressed air as the gas.

It is preferable that the paint container is detachably provided on a holding portion capable of detachably holding a writing instrument. In other words, the airbrush body is
It is preferable that the paint container is provided with a holding portion capable of detachably holding the writing instrument, and the paint container is formed in a shape capable of being detachably held by the holding portion. In this case, if the paint container is removed from the holding portion and a writing implement is attached to the holding portion, the ink of the writing implement can also be used as a paint,
The simplicity of a writing instrument can also be obtained.

[0009] In addition, the airbrush may include, in addition to the above-described configuration, or simply a "paint container or writing implement provided on the airbrush main body provided with an airbrush main body having a gas jetting nozzle by jetting gas from the gas jetting nozzle. In the configuration of `` airbrush that performs painting by sucking paint from '', the airbrush main body is attached with a mounting portion for mounting a gas cylinder configured so that gas flows out from the pipe portion by pushing the pipe portion. A gas flow path from a pipe portion of the gas cylinder to the jet nozzle, a gas amount adjustment operation unit for adjusting a pushing amount of the pipe portion to adjust an outflow amount of gas from the cylinder, and a gas flow passage. A jet operation unit for opening and closing to operate jetting and stopping of the gas from the jet nozzle. Can.

[0010] Here, it is known that a conventional airbrush is provided with an operation section for controlling gas ejection in the airbrush body. In the present invention, for the purpose of simplifying the configuration and facilitating use, a configuration in which a gas cylinder mounting portion is provided on the airbrush main body and the gas cylinder is directly mounted on the airbrush main body (without a hose) is employed. On the premise of the above, a gas amount adjusting operation unit and an ejection operation unit are provided. Here, it is conceivable to provide only one operation part for pushing the pipe part of the gas cylinder. In this case, in order to adjust the gas ejection amount, it is necessary to change the operation amount of the operation part at the time of gas ejection. And uniform coating may be difficult.

On the other hand, in the present invention, since the gas amount adjusting operation unit and the ejection operation unit are provided separately, for example, the gas amount is adjusted in advance by operating the gas amount adjusting operation unit in trial coating. When the desired ejection amount is obtained, the painting can be performed with a uniform ejection amount by operating the ejection operation unit. Further, it is preferable that the gas amount adjusting operation unit includes an adjusting lever and a pushing body that is rotated by a screw mechanism and pushes the pipe into the pipe.

It is a known form that can be seen. A gas (air) amount adjusting operation unit 15 is provided below the grip unit 5. The adjusting operation section 15 pushes the pipe section 12 by operating an adjusting lever 16 to adjust the amount of air flowing out of the cylinder 2. The adjusting operation section 15 includes a pushing body 17 that is fitted to the outside of the pipe section 12 and is movable in the vertical direction. As shown in FIGS. 4 and 5, a male screw 18 is formed on the outer periphery of the pushing body 17, and is screwed with a female screw 19 formed inside the airbrush main body 3, so that the pushing body 17 is formed. A screw mechanism that moves up and down when rotated is configured. The male screw 18 may be formed on the airbrush main body 3 and the female screw 19 may be formed on the pressing body 17.

The adjustment lever 16 is provided integrally with the pressing body 17 and is exposed outside the airbrush main body 3. By operating this adjustment lever 16 in the left-right direction,
The pressing body 17 moves up and down, and the outflow amount of air can be adjusted steplessly from a state in which no air flows out. A passage through which air flows is formed in the pressing body 17 in a vertical direction. An air passage reaching the ejection nozzle 6 is formed inside the airbrush main body 3 including the internal passage of the pressing body 17.

A valve 20 is provided in the middle of the air passage, and air can be flowed or shut off by opening and closing the valve. Specifically, the valve 20 is disposed inside the grip portion 5, is connected to the pressing body 17 by a pipe 21, and is connected to the ejection nozzle 6 by a pipe 22. The valve 20 includes a valve body 24, a valve shaft 25, and a spring 26, as shown in FIG. The valve body 24 has an air inlet 27,

When the paint container 30 is mounted on the holder 31, the paint nozzle 38 is located near the front of the jet nozzle 6. Therefore, when air is jetted from the jet nozzle 6, the jetted air sucks the paint in the paint container 30 and is atomized, so that painting can be performed. The discharge amount of the paint from the paint nozzle 38 can be adjusted by the size of the hole 39 of the lid 37. To increase the discharge amount, the size of the hole 39 is increased. To decrease the discharge amount, the size of the hole 38 is reduced. Further, when the viscosity of the paint is high, the size of the hole 39 is increased to allow a large amount of air to flow therein to obtain a pressure substantially equal to the atmospheric pressure, so that the paint is easily discharged from the paint nozzle 39, and the viscosity of the paint is low. In this case, the size of the hole 39 is reduced to reduce the inflow of air,
The internal pressure can be reduced to make the paint difficult to come out.

As a method of adjusting the size of the hole 39, a plurality of lids 37 having different sizes of the holes 39 are prepared, and the lid 37 having the holes 39 according to the viscosity of the paint is selected, and the container body 35 is selected.
