囲にはみ出して窓枠等にも付着する欠点があった。The above-mentioned conventional foaming nozzle is formed in a cylindrical shape. When a trigger of a trigger type sprayer equipped with the nozzle is operated, the nozzle passes through a spin passage of the nozzle of the sprayer. The outer surface of the group of fog spouted into the shape of a hollow cone by spinning from the spray hole hits the inner surface of the mouth of the foaming nozzle, foams, and spouts out as a group of bubbles having a circular cross section. Therefore, in the case of a trigger type sprayer with a foaming nozzle, for example, when a detergent is sprayed on a window glass, the bubbles are adhered in a circular shape. There was a drawback that it protruded and adhered to window frames and the like.

る。When the spraying operation is performed with the spray nozzle 2 directed forward, the liquid spouts forward while rotating at a high speed through a known spin passage 4 provided on the inner surface of the spray hole 3. Due to the high speed rotation, the liquid is atomized immediately, and many of the particles of each mist draw a spiral trajectory whose diameter increases as the distance from the spray hole increases. In the form of a ring having a substantially hollow conical shape at an angle, that is, a ring shape having a wide cross-section, the concentration of the outer peripheral portion is high, and the central portion excluding the high-concentration ring-shaped portion is diluted and foamed attached to the spray nozzle 2 It gushes through the nozzle 7. In the portion where the fog group hits the inner wall surface of the mouth, the mist particles that collide with the inner wall surface of the mouth are foamed by mixing with the outside air flowing into the foaming nozzle through the space between the front end face of the spray nozzle and the rear end face of the foaming nozzle. The bubbles are mixed with the non-foaming fog, and are ejected from the mouth of the foaming nozzle into a truncated quadrangular pyramid with a substantially square cross section.

への霧群外側部分の衝突範囲を示す。[0010] foam nozzle 7 is located as Ho Isuzu square tube has viewed forward, the central axis of the foam nozzles are is positioned on the extension of the spray hole central axis. As shown in the figure, a fog guide piece 8 may be provided on the inner surface of the cylindrical wall portion forming the foaming nozzle. As shown in FIG. 3, the position of the foaming nozzle 7 is such that the outer surface portion 9a of the mist group 9 which is ejected in a hollow cone shape from the spray hole 3 through the foaming nozzle at a constant spray angle has a foaming nozzle opening as shown in FIG. The square is formed so as to hit the inner surface of the middle part of each side and to be able to pass through the front ends of the four corners including both ends of each side. The fog group that hits the middle part of each side foams, and the bubbles generated in this way become a group of bubbles by mixing with the fog ejected without hitting the inner surface of the mouth of the foaming nozzle, and the four corners front end part Are scattered in the direction of arrow A extending the outer surface portion 9a. Further, the foam generated in the middle portion of each piece tends to squirt in the direction of arrow B extending forward along the inner wall surface of the foaming nozzle, but tends to scatter in the direction of arrow C in the vicinity of the middle portion of the edge. By mixing with the mist, the mist is ejected in the direction of arrow D between the arrows B and C. The foam group 10 sprayed on the wall surface to be sprayed in this way forms a square having a circumscribed circle as a perfect circle 11 as an extended partial cross section of the conical fog group 9 described above. Numeral 12 indicates the range of collision of the outer portion of the fog group with the inner wall portion of the foam nozzle opening.

散することによるものと考えられる。When the collision area 12 on the outer surface of the fog group increases as shown in FIG. 11, the shape of the group of bubbles sprayed on the surface to be sprayed becomes a cross-shaped star shape 13 and the mixing of the fog and the bubbles is improper. When completed, fog is distributed to the portion of the arm 14 protruding outward, and bubbles are unevenly distributed to the central portion 15 excluding the arms. The reason is that almost all of the high-concentration parts on the outer periphery of the fog group hit the collision area 12 and the amount of foaming became too large,
As a result, the amount of mist scattered in the direction of arrow C is reduced, and bubbles are squirted in the direction of arrow B at the middle of each side, while high-density mist is scattered in the direction of arrow A without foaming at the four corners of the mouth. It is thought that it is due to doing.

付けが得られた。In the case where the foaming nozzle 7 is a substantially square tube , as in the second embodiment shown in FIGS. 4 to 7, an arc-shaped tube is formed between both ends of the front surface of each side of the square tube formed by the foam nozzle opening. It is desirable to form the recess 16. By forming the collision range 12 along the rear of the arcuate concave portion, the collision range can be widened over the entire inner surface of the mouth without being partially biased. The example provided a spray of foam with a substantially uniform concentration.

態で当たることによる。FIGS. 8 to 10 show a third embodiment. This embodiment shows a case where the foaming nozzle is a rectangular cylinder when viewed from the front. In the case of a rectangular tube as described above, an arc-shaped concave portion 16 is provided on the front surface of the long side 7a of the mouth portion, and the outer surface portion of the mist group 9 ejected through the bubbling nozzle is formed by the arc-shaped concave portion 16.
It is provided so that it is relatively deep on the inner surface side, relatively shallow on the inner surface side of the short side 7b, and passes near the four corner front ends. For foaming nozzle of the rectangular tube, FIG. 1
The fog group collision area 12 on the long side 7a side indicated by 0 is the short side shown in FIG.
It is significantly larger than the fog group collision area 12 on the 7b side, but this is at a different distance from the spray hole 3, so that the outer surface of the fog group 9 ejecting in a hollow cone shape is faster on the long side, and therefore This is due to the contact in the small cross section state and the slowness on the short side, and therefore the collision in the large cross section state.

い。The spray angle of the mist of the mist group 9 is determined by the number of rotations of the spray pressure spin, the length and the diameter of the spray hole, and many other conditions. Therefore, the trigger type sprayer for mounting the foaming nozzle is the same. It must be manufactured in dimensions.
For fine adjustment of the spray angle, the spray nozzle 2 is connected to the injection pipe 1 or the cylinder 6 with the foaming nozzle is connected to the spray nozzle 2.
May be screwed together, and the spray nozzle may be screwed with respect to the injection pipe, or the cylinder may be screwed with respect to the spray nozzle.

グを容易かつ迅速に行うことができる。The present invention has the above-mentioned structure, and the foam generated by colliding with the inner surface of the mouth is not affected by the outer portion of the mouth, and the corner is formed without colliding with the mouth despite almost losing the ejection power to the outside. Since the passing mist jumps out of the mouth without losing the jetting power, the mist attracts the bubbles and jets out as a group of mist bubbles having a square cross section. Therefore, a square or short foam group can be sprayed by spraying on a glass window or the like, so that the detergent foam is sprayed so that the corners of the spray group correspond to, for example, the corners of a glass window or the like. Thus, the glass window can be easily and quickly cleaned.
