Airbrush capable of consistently outputting paint

Abstract

This invention comprises a pen body, a nozzle holder housing, and a nozzle seat. The pen body has a receiving groove and an air supply channel communicating with the interior of the receiving groove; the receiving groove is located at one end of the pen body. The nozzle holder housing is integrated with the pen body, covers the receiving groove, and includes a housing with an air outlet. The nozzle seat is located inside the nozzle holder housing, between the nozzle holder housing and the pen body, and together with the receiving groove, forms a pressure-stabilizing space. The nozzle seat has an air supply channel communicating with the pressure-stabilizing space and the interior of the nozzle holder housing. The pressure-stabilizing space of this invention allows the pressurized airflow from the pen body to be stabilized first, solving the problem of existing airbrushes being unable to accurately control paint output when pressure and flow decrease, thus providing an airbrush that can stably output paint.

Claims

1. An airbrush capable of stably outputting paint, comprising: a brush body including a reservoir and an air supply channel; the reservoir being disposed at one end of the brush body; the air supply channel being disposed inside the brush body, extending to the bottom of the reservoir and communicating with the interior of the reservoir; a nozzle seat housing, which is attached to the brush body, covers the reservoir, and includes a housing, the housing including an output end and an input end positioned opposite each other, and an air outlet at the output end; and a nozzle seat, which is attached inside the nozzle seat housing, located between the nozzle seat housing and the brush body, and together with the reservoir forming a pressure-stabilizing space, the nozzle seat including a central post, a paint channel, and at least one air supply channel; the central post including an output end and an input end positioned opposite each other; the paint channel being disposed inside the central post and extending to the output end and the input end, the at least one air supply channel communicating with the pressure-stabilizing space and the interior of the nozzle seat housing; wherein, The nozzle seat includes a sleeve located at the feed end of the central column and having a tapered outer diameter.

2. The spray gun capable of stably outputting paint as described in claim 1, wherein the nozzle seat is provided with three air channels arranged at equal angles around the paint channel.

3. The spray gun capable of stably outputting paint as claimed in claim 2, wherein the housing includes a receptacle extending toward the output end of the housing; the nozzle seat includes a neck disposed opposite to and fitted into the receptacle.

4. The spray gun capable of stably outputting paint as described in claim 3, wherein the nozzle seat includes a flange and abuts against the input end of the housing.

5. The spray gun capable of stably outputting paint as described in claim 4, wherein the nozzle housing includes a connecting section disposed at the input end of the housing and having an external thread on its outer peripheral surface; the inner peripheral surface of the receiving groove has an internal thread; the external thread of the connecting section is screwed into the internal thread of the receiving groove.

6. The spray gun capable of stably outputting paint as described in claim 5, wherein the nozzle seat includes an internally threaded section located at the discharge end of the central post and having an internal thread on the inner circumferential surface of the paint channel.

7. An airbrush capable of stably outputting paint as described in claim 6, wherein the nozzle seat includes a sleeve located at the feed end of the central post.

8. The spray gun capable of stably outputting paint as claimed in claim 1, wherein the housing includes a receptacle extending toward the output end of the housing; the nozzle seat includes a neck disposed opposite to and fitted into the receptacle.

9. An airbrush capable of stably outputting paint as claimed in claim 1, wherein the nozzle seat includes a flange and abuts against the input end of the housing.
