本考案は、高速空気流中に吸水ノズルの噴出口
を配置してその噴出口を負圧にし、水を吸い上げ
て噴霧する噴霧器のノズルの改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a nozzle for a sprayer that places a water-absorbing nozzle jet in a high-speed air flow to create a negative pressure in the jet port to suck up and spray water.
一般に、噴霧器のノズルは、空気を圧送する管
の先端に細孔を有して空気を吹き出す吐出ノズル
と、その吐出ノズルの先端近くに噴出口を位置さ
せて吐出ノズルから吹き出す高速空気流によつて
噴出口を負圧にし、水を吸い上げて霧状に噴出す
る吸水ノズルとからなる。 In general, the nozzle of a sprayer has a discharge nozzle that has small holes at the tip of a pipe that pumps air and blows out air, and a discharge nozzle that is located near the tip of the discharge nozzle and uses a high-speed air flow that is blown out from the discharge nozzle. It consists of a water suction nozzle that creates negative pressure at the spout, sucks up water, and sprays it out in the form of mist.
従来、前記噴霧器のノズルを改良したものとし
て、第１図に示すものが知られている（特公昭50
−6363号公報）。これは、液体１を吸い上げて噴
霧する吸水ノズル２の噴出口先端開口面を、吸水
ノズル２の軸心に斜めに交わる仮想平面上に位置
するように構成したものである。 Conventionally, as an improved version of the nozzle of the sprayer, the one shown in Fig. 1 is known (Japanese Patent Publication No. 50
-6363). This is configured such that the opening surface of the spout end of the water suction nozzle 2 that sucks up and sprays the liquid 1 is located on a virtual plane diagonally intersecting the axis of the water suction nozzle 2.
しかし、高速空気流を吹き出す吐出ノズル３の
吹出し口３ａと、水を吸い上げてそれを霧状にし
て噴出する吸水ノズル２の噴出口２ａとの距離
は、噴出口２ａの負圧が変化して噴霧効率に大き
な影響を与えるので、従来の吸水ノズル２の噴出
口２ａのように斜めの切断面を有する場合は、噴
出口２ａの高さが吹出し口３ａより漸次低くなる
ために両ノズルの位置関係が極めて困難になる。
つまり、吸水ノズル２の噴出口先端開口面は、吐
出ノズル３の軸心Ａ上にあることが望ましい。 However, the distance between the outlet 3a of the discharge nozzle 3, which blows out a high-speed air flow, and the outlet 2a of the water suction nozzle 2, which sucks up water and sprays it in the form of mist, is determined by changes in the negative pressure at the outlet 2a. This has a large effect on spray efficiency, so if the jet nozzle 2a of the conventional water absorption nozzle 2 has an oblique cut surface, the height of the jet nozzle 2a will gradually become lower than the jet nozzle 3a, so the position of both nozzles may be changed. Relationships become extremely difficult.
In other words, it is desirable that the opening surface of the ejection port end of the water suction nozzle 2 be on the axis A of the discharge nozzle 3.
そこで、本考案は、吸水ノズルの噴出口内周端
に斜面を設けることによつて上記欠点を解消し、
組立てが容易であり、しかも噴霧量が増加する噴
霧器のノズルを提供せんとするものである。 Therefore, the present invention solves the above-mentioned drawbacks by providing a slope at the inner circumferential end of the spout of the water absorption nozzle.
It is an object of the present invention to provide a nozzle for an atomizer that is easy to assemble and increases the amount of spray.

と、45゜の場合に最大噴霧量が得られた。 Embodiments of the present invention will be further described below based on the drawings. FIG. 2 is an enlarged cross-sectional view of the nozzle of the atomizer. Reference numeral 11 is a water suction nozzle, 12 is a discharge nozzle, and the water suction nozzle 11 is connected to a storage tank 14 in which water 13 is stored. The discharge nozzle 12 blows out air compressed by a compressor 15 such as an air pump as a high-speed air stream from an outlet 12a at its tip, and is arranged horizontally. The water suction nozzle 11 is arranged so that the spout 11a of the water suction nozzle 11 is located near the tip of the discharge nozzle 12, and the axis of the water suction nozzle 11 and the axis of the discharge nozzle 12 are substantially perpendicular to each other. The upper edge of the spout 11a of the water suction nozzle 11 is perpendicular to the axis A of the discharge nozzle 12, and the inner peripheral end of the spout 11a has a
A slope 11b is provided. Inclination angle α of this slope 11b
According to the experiment, the inner diameter of the water absorption nozzle 11 is 0.8
mm, the inner diameter of the discharge nozzle 12 was 0.5 mm, and the air blowing pressure from the discharge nozzle 12 was 0.2 Kg/cm 2 , the maximum spray amount was obtained at 45°.

る。 In the nozzle of the atomizer having the above configuration, the high-speed airflow blown out from the discharge nozzle 12, especially the flow in the lower layer, flows smoothly along the slope 11b of the water suction nozzle 11, and Since the air flow velocity does not decrease and furthermore, the upper edge of the jet nozzle 11a is on the same horizontal plane, the negative pressure at any point in the jet nozzle 11a is approximately constant.

しかも噴霧量の増加が図れる利点がある。 Therefore, according to the present invention, there is no need to delicately change the positional relationship between the outlet of the water suction nozzle and the outlet of the discharge nozzle, and assembly is simple.
Moreover, there is an advantage that the amount of spray can be increased.
