Description

[Technical Field]

[0001] The present invention relates to an air brush that, when compressed air is sprayed from a nozzle, sucks in paint by the suction force of the compressed air and sprays it in the form of a mist. [Background technology]

[0002] Generally, if the aftercare of an airbrush is neglected after use, the needle insertion hole may become clogged, and therefore the airbrush must be periodically disassembled for inspection and maintenance.

[0003] It is also necessary to replace the nozzle with one of a diameter appropriate for the painting job, etc.

[0004] Conventionally, various types of air brushes of this type have been proposed.

[0005] For example, Patent Document 1 discloses an airbrush in which the nozzle can be detached from the main body.

[0006] This air brush has a nozzle that is screwed onto the front end of the body, and a nozzle cap that is screwed onto the outer periphery of the nozzle. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Japanese Patent Application Laid-Open No. 2001-79458 Summary of the Invention [Problem to be solved by the invention]

[0008] However, this airbrush is configured so that the nozzle is screwed onto the main body and then the nozzle cap is screwed onto the nozzle, making inspection and nozzle replacement cumbersome. Furthermore, because the nozzle must be provided with threads for screwing onto the main body and the nozzle cap, the nozzle is fragile and prone to damage.

[0009] The present invention has been made in light of the above circumstances, and an object of the present invention is to provide an air brush that is easy to inspect and that can prevent damage to the nozzle. [Means for solving the problem]

[0010] In order to solve the above problems, the airbrush of the present invention is characterized by comprising a needle, a body having an insertion hole through which the needle is inserted, a nozzle arranged at the tip of the body so as to communicate with the insertion hole, and a nozzle cap that presses the nozzle against the body. [Effects of the Invention]

[0011] The air brush according to the present invention is easy to inspect and can prevent damage to the nozzle. [Brief explanation of the drawings]

[0012] The drawings illustrate particular embodiments of the present invention, including essential features of the invention as well as alternative and preferred embodiments. [Figure 1] 1 is a side view showing an airbrush according to an embodiment of the present invention; [Figure 2] FIG. [Figure 3] FIG. [Figure 4] FIG. [Figure 5] FIG. DETAILED DESCRIPTION OF THE INVENTION

[0013] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0014] In FIG. 1, reference numeral 1 denotes an airbrush according to one embodiment of the present invention.

[0015] This airbrush 1 has an elongated shaft-shaped main body 2, which is provided with a cup mounting portion 4 for mounting a paint cup 3, an air pressure adjustment valve 5, an operating lever 6, and an air connection portion 9 for connecting an air valve 8 of a compressor 7.

[0016] Furthermore, a nozzle cap 10 and a needle cap 11 are attached to the tip of the main body 2.

[0017] Furthermore, a tail cap 12 and a needle opening adjustment screw 13 are attached to the rear end of the main body 2.

[0018] As shown in FIGS. 2 and 3, a needle 14 is inserted into the main body 2.

[0019] That is, the main body 2 is formed with an insertion hole 15 through which the needle 14 is inserted, and the needle 14 is fitted into the insertion hole 15 with a loose fit.

[0020] Further, the main body 2 is formed with an introduction hole 16 for introducing the paint in the paint cup 3 into the insertion hole 15 , and the paint introduced into the insertion hole 15 is supplied to a nozzle 17 .

[0021] Furthermore, the main body 2 is formed with an introduction passage 18 that introduces compressed air from the compressor 7 between the nozzle 17 and the nozzle cap 10.

[0022] A needle chuck guide 19 is fixed to the rear end side of the needle 14 by a needle chuck nut 20 .

[0023] The needle chuck guide 19 is inserted through a lever adjuster 21 attached to the rear end of the main body 2 and is guided by this lever adjuster 21 so as to be slidable.

[0024] A compression spring 22 and a spring case 23 are fitted onto the needle chuck guide 19 , and the needle 14 is biased toward the rear end of the main body 2 by the compression spring 22 .

[0025] Furthermore, a lever guide 24 that engages with the operating lever 6 is attached to the tip of the needle chuck guide 19, so that when the operating lever 6 is tilted backward, the needle 14 can slide backward of the main body 2 against the biasing force of the compression spring 22.

[0026] In addition, an operating rod 25 for operating the opening and closing of the air valve 8 is attached to the operating lever 6, and when the operating lever 6 is pressed down, the air valve 8 can be opened.

[0027] As shown in FIG. 5, the nozzle 17 is pressed against the main body 2 by the nozzle cap 10.

[0028] That is, the main body 2 and the nozzle cap 10 are provided with threaded portions 26 that screw together with each other, for example, a female thread 27 on the main body 2 and a male thread 28 on the nozzle cap 10, and by tightening these threaded portions 26, the nozzle 17 is pressed against the main body 2 so that it communicates with the insertion hole 15.

[0029] A packing 29 through which the needle 14 is inserted is provided between the main body 2 and the nozzle 17 , and this packing 29 is configured to fit onto the end of the nozzle 17 .

[0030] That is, a rear end step 30 is formed at the rear end of the nozzle 17, and a packing 29 is fitted into this rear end step 30.

[0031] Furthermore, the nozzle cap 10 is provided with an inner wall portion 31 that abuts against the tip of the nozzle 17.

[0032] That is, a tip step portion 32 is formed at the tip of the nozzle 17, and the inner wall portion 31 of the nozzle cap 10 abuts against this tip step portion 32, and by tightening the nozzle cap 10, the nozzle 17 is pressed against the main body 2 together with the gasket 29.

[0033] In this configuration, when the operating lever 6 is pressed down, compressed air from the compressor 7 is supplied via the introduction path 18 and is ejected from the tip.

[0034] Next, when the operating lever 6 is tilted backward, the needle 14 slides backward, and the ejector effect of the compressed air sprayed from the gap between the nozzle 17 and the nozzle cap 10 causes the paint in the paint cup 3 to pass through the insertion hole 15 and the nozzle 17 and be sprayed in a mist from the tip of the nozzle 17.

[0035] When inspecting the air brush 1 or replacing the nozzle 17, the nozzle 17 and the packing 29 can be removed simply by removing the nozzle cap 10.

[0036] According to the above configuration, the nozzle 17 is pressed against the main body 2 by the nozzle cap 10, so that the nozzle 17 can be easily removed by simply removing the nozzle cap 10.

[0037] Moreover, since there is no need to form a thread on the nozzle 17, damage to the nozzle 17 can be prevented.

[0038] The disclosure of the present invention described above can be summarized at least as follows.

[0039] That is, the airbrush according to the present invention is characterized by comprising a needle, a body having an insertion hole through which the needle is inserted, a nozzle arranged at the tip of the body so as to communicate with the insertion hole, and a nozzle cap that presses the nozzle against the body.

[0040] The present invention can include at least the following embodiments, which can be adopted separately or in combination with each other.

[0041] (1) It is preferable that the main body and the nozzle cap are provided with threaded portions that are screwed together, and that the nozzle is pressed against the main body by tightening these threaded portions.

[0042] (2) It is preferable to provide a packing between the body and the nozzle through which the needle passes, and to configure this packing so as to fit onto the end of the nozzle.

[0043] (3) The nozzle cap preferably has an inner wall that abuts against the tip of the nozzle. [Explanation of symbols]
