Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a nozzle device for an atomizer.

A conventional sprayer nozzle device will be explained with reference to FIGS. 1 and 2. Water in a tank 102 stored in an outer case 101 is heated and boiled by a heater 103, becomes pressurized steam, passes through a steam pipe 104, and is ejected from a blow-off nozzle 105. The nozzle holder 107 holds the blowout nozzle 1 so that the tip of the suction nozzle 106 is located in the jetted steam flow.
05 and the suction nozzle 106 are fixed. The suction nozzle 1 is
The chemical liquid 110 in the chemical liquid cup 109 is sucked up through the tube 108 connected to the chemical liquid cup 109, mixes with the ejected steam, and is dissipated forward. Chemical liquid cup 1
The role of the nozzle device is important to ensure that the chemical solution 110 in the 09 mixes with the ejected steam in a quantitative and reliable manner and dissipates it forward, and it is necessary to always maintain a constant mounting positional relationship between the blow-off nozzle 105 and the suction nozzle 106. Therefore, it was necessary to strengthen the nozzle holder 107. Conventional nozzle holder 107
When some external force is applied, the center of the pore 112 of the suction nozzle 106 shifts from the center of the pore 111 of the blow-off nozzle 105, as shown in FIG.
It had the disadvantage that 0 could no longer be sucked up. In order to prevent this, reinforcing ribs 113 are provided on the nozzle holder 107 as shown in FIG. 4 to make it stronger to some extent, or the hardness of the material is increased to increase the bending strength of the nozzle holder 107. . However, the nozzle holder 107, which is pressed into a flat plate, has a limit in firmly attaching both nozzles 105 and 106, and each nozzle component is assembled by brazing using a jig, but in reality, the nozzle The accuracy of mounting dimensions was difficult to maintain, the defective rate during assembly was high, and corrections were difficult, resulting in wasted materials.

The present invention solves the above-mentioned conventional drawbacks, and one embodiment of the present invention will be described below with reference to FIGS. 5 and 6.

1 is a steam pipe, 2 is a blowing nozzle, 3 is a suction nozzle, 4 is a pipe-shaped nozzle holder for holding the nozzle, and 5 is a suction tube.

For the nozzle holder 4, a pipe with an inner diameter corresponding to the outer diameter of the blowout nozzle 2 and suction nozzle 3 is selected, a part of the center part of the pipe is cut out, and the tips of both nozzles are bent in the direction where the tips of both nozzles meet with the cutout part. Process. Insert the blowout nozzle 2 and the suction nozzle 3 from both ends of the bent nozzle holder 4, position them using a special jig (not shown), and fix both nozzles and the nozzle holder with adhesive, brazing, etc. Alternatively, make the outer diameter of both nozzles a little larger and press fit them into the nozzle holder 4.
Fix it.

In the nozzle device configured in this way, since the nozzle holder 4 is a pipe, the center line of the pipe and the center lines of both nozzles are on the same line, which facilitates positioning during assembly and greatly reduces machining defects. In addition, since the nozzle holder 4 has a semi-cylindrical cross section, it is much stronger against external forces such as bending and twisting than a conventional plate-like cross section, so the installation position of each nozzle will not easily shift. do not have. Furthermore, since the nozzle holder 4 has a small shape, the shape of the inhaler body can also be made small, making it easier to use.

As described above, according to the present invention, positioning during assembly is easy, the manufacturing yield is high, resources are saved, and the device is strong against external forces and has useful effects.
