However, it is preferable that the material accommodated therein has a circular cross-sectional shape in order that the body 100 may have a small amount of residual material and is easily cleaned.

The material of the present invention may be any material as long as it can be sprayed in the form of a liquid such as paint, oil stain, or pesticide. This material is introduced into the body 100 through the material inlet pipe 140 formed at the upper end of the body 100. The material inlet pipe 140 is connected to the upper surface of the body 100 by communicating with the interior of the body 100 And may be formed to communicate with the inside of the body 100 on one side of the upper end of the body 100. [

The material inlet pipe 140 may be formed in various shapes, but it is preferable that the material inlet pipe 140 is bent at least once as shown in FIGS. 2 and 3, and more preferably has a shape bent upward Do. This is to prevent the material from flowing backward by the compressed air flowing into the body 100. For example, the material inlet pipe 140 may be formed in the shape of 'A'.

In addition, the material inlet pipe 140 may be formed with an open / close valve 141 that opens or closes the material inlet pipe 140 as shown in FIG. The opening / closing valve 141 blocks the material inlet pipe 140 as shown in FIG. 4A through rotation to prevent the material from being injected from the outside into the body 100, and the material contained in the body 100 Do not reflux to the outside. In addition, the opening / closing valve 141 may be rotated to open the material inlet pipe 140 as shown in FIG. 4B so that the material can be introduced into the inside of the body 100 from outside.

2 and 3, the lower portion of the body 100 is tapered toward the inside. As shown in FIG. 5, the liquid material injected into the material inlet pipe 140 flows down along the inner side of the body and is concentrated to the lower end of the body 100, So that the gun (10) can escape without leaving any residue.

6, the airless sprayer of the present invention is provided with a cleaning device on the upper side of the body 100. Specifically, the airless sprayer of the present invention includes a cleaning tank (not shown) for receiving a cleaning liquid such as a thinner, And an injection port 120 for receiving the cleaning liquid from the cleaning tank 110 and spraying the cleaning liquid into the body 100 is provided at an inner upper end of the body 100.

The lower end of the washing tank 110 and the upper end of the body 100 communicate with each other through the washing liquid inlet pipe 130 to supply the washing liquid from the washing tank 110 to the body 100, And the cleaning liquid is sprayed through the injection port 120 provided at one end of the nozzle.

In order to form the spraying pressure required for spraying the cleaning liquid into the body 100, the cleaning liquid inlet pipe 130 may be formed of a tube having the same diameter as the downward direction as shown in FIG. 7, Can be formed to gradually decrease. The cleaning liquid inlet pipe 130 may be formed such that one pipe is tapered toward the inside, that is, the inside diameter gradually decreases. In addition, the plurality of pipes having different diameters are arranged in the order of decreasing diameters Or may be formed in a communicated form. Thus, the cleaning liquid can be discharged into the body 100 without leaving a cleaning liquid due to a bottleneck at the lower portion of the cleaning tank 110.

The washing fluid inlet pipe 130 may be provided with a valve for opening or closing the washing fluid inlet pipe 130. The washing fluid inlet pipe 130 may be opened when the inside of the body 100 is cleaned by adjusting the valve, When the cleaning liquid is not cleaned, the cleaning liquid inlet pipe 130 is blocked to prevent the compressed air from escaping to the outside or the material flowing backward and being discharged to the outside.

Also, the cleaning liquid inlet pipe 130 may be formed to be movable along the longitudinal direction within the body 100. Since the injection port 120 is provided at the upper end of the inside of the body 100 and the lower portion of the body 100 is tapered toward the inside, the cleaning liquid is uniformly sprayed to the inner surface of the body 100, 130 can be moved upward or downward from the inside of the body 100 and the washing liquid can be injected strongly throughout the body 100 by changing the position where the washing liquid is injected.

Meanwhile, the cleaning liquid contained in the cleaning tank 110 may be moved downward toward the interior of the body 100 in various manners, for example, air pressure may be used. An air inlet 111 for injecting air can be formed at an upper end of the washing tank 110. An operator can directly blow air into the air inlet 111 or blow air through an air compressor 200 By injecting the compressed air, the washing liquid contained in the washing tank 110 can be injected from the injection port 120 through the washing liquid inlet pipe 130.

In addition, the injection port 120 may inject the cleaning liquid into the body 100 in various manners. For example, a hole may be radially formed at one end of the washing liquid inlet pipe 130 so that the washing liquid may be injected into the hole by the spraying pressure described above. In another example, an injection port 120 rotatable in the transverse direction is provided at one end of the cleaning liquid inlet pipe 130 so that the cleaning liquid dropped downward through the cleaning liquid inlet pipe 130 rotates through the injection port 120 It may be strongly scattered and injected into the body 100. In this case, the cleaning liquid can be uniformly sprayed evenly on the inner surface of the body 100, which is more effective than the above-described example.
