状にして噴出するものである。[Detailed Description of the Invention] The present invention relates to a nozzle structure of a sprayer. A sprayer uses an air blowing nozzle that has a fine hole at the tip of a tube that pumps air, and a high-speed airflow that blows out from the fine hole of the blowing nozzle with the outlet facing the tip of the blowing nozzle. It has a nozzle part consisting of a liquid suction nozzle that sucks up liquid, and the liquid flowing out from the tip outlet of the liquid suction nozzle is atomized by pressurized air and ejected.
そこで、従来の噴霧器におけるノズル部は、第

にしている。そして、吹出しノズル１の先端かど
は、切頭円錐状になつた吸液ノズル２の先端部外
面に接触して細孔１ｃと液体の出口２ｄとを近接
させている。 Therefore, as shown in FIG. 1, the nozzle section of a conventional sprayer includes a liquid suction nozzle 2 that flows out liquid to a tip 1a of a blow-off nozzle 1 that sends out pressurized air.
The tip 2a of the nozzle 1 is positioned so that the surface 2c of the tip 2a is slightly below the axis of the blow-off nozzle 1. The tip corner of the blowout nozzle 1 contacts the outer surface of the tip of the liquid suction nozzle 2, which has a truncated conical shape, to bring the pore 1c and the liquid outlet 2d close to each other.
しかし、吹出しノズル１からの圧送空気は、細
孔１ｃを通過したならばそのまま大気中に放出さ

出口２ｄ上における空気の流量は細孔１ｃを通過
する量よりも減少するので吸液ノズル２で吸い上
げられる液体の量も減少し、噴霧量は少なくなる
欠点があつた。 However, once the pressurized air from the blowout nozzle 1 passes through the pore 1c, it is released into the atmosphere as it is, so it flows over a wide range, and the flow rate of air above the outlet 2d of the liquid suction nozzle 2 is the same as the pore 1c. Since the amount of liquid that is sucked up by the liquid suction nozzle 2 decreases compared to the amount that passes through the liquid, the amount of liquid sucked up by the liquid suction nozzle 2 also decreases, resulting in a disadvantage that the amount of spray is reduced.

である。 Therefore, the present invention aims to provide a nozzle structure for a sprayer that eliminates the above-mentioned drawbacks. The present invention is characterized in that at least one of two parallel guide walls, which are sloped or run in the same direction as the axis of the blow-off nozzle, is provided at the tip corner of the portion covered by the extension.

Its length is limited so that it does not fall within 2. The liquid suction nozzle 12 is arranged upward at right angles to the horizontal axis of the blow-off nozzle 11, and its lower end is connected to a tank (not shown), and its upper end surface 12a is slightly below the axis of the blow-off nozzle 11. The outlet 12b on the upper end surface is located close to the tip of the blow-off nozzle 11. A slope 12c is provided at the outer circumferential corner of the thick portion 12d of the upper end of the liquid suction nozzle 12, which is covered by the extending portion 11b of the blowout nozzle 11. Therefore, the slope 12c faces the outlet at the tip of the blow-off nozzle 11, and is covered by the extending portion 11b.

出される。 According to the nozzle structure of the sprayer of the present invention, compressed air from an air compressor (not shown) is blown out from the tip of the blow-out nozzle as a high-speed air current passing over the upper end of the liquid suction nozzle. This air current flows over the upper end of the liquid suction nozzle without being significantly reduced in speed by the inclined surface, and further,
In the case of the guide wall 22d as shown in Fig. 3, the air current above the upper end of the suction nozzle 22 is concentrated by the guide wall 22d and flows in the axial direction of the blow-out nozzle 21 without reducing the flow rate. The high-speed air current creates negative pressure inside the suction nozzle, so that liquid is sucked up from a tank connected to the lower end of the nozzle. The liquid that has risen up the suction nozzle and flowed out of the upper outlet is sprayed out in the form of a mist by the compressed air from the blow-out nozzle.

cm 2 , the inner diameter of the outlet of the blowout nozzle was 0.8 mm, and the inner diameter of the outlet of the liquid suction nozzle was 0.7 mm. As a result, the spray amount with the conventional nozzle structure was 3.4cc/mm, and with the nozzle structure shown in Figure 2,
A spray amount of 13.5 cc/mm was obtained, and in the case of the nozzle structure shown in FIG. 3, a spray amount of 11.9 cc/mm was obtained.
