JPS6032816Y2 - humidifier spray nozzle - Google Patents

Description

[Detailed description of the invention] The spray nozzle 1 of a conventional humidifying device has a cap shape with a discharge port 2 opening obliquely upward as shown in Fig. 1a and b. In this case, the mist from the humidifier main body (not shown) hits the sloped upper inner surface of the discharge port 2 and becomes water droplets, which turn into large water droplets due to the surface tension and stick to the water, which not only adversely affects the amount of spray but also However, the attached water droplets were visible from the front of the nozzle, giving an unsightly impression.

The present invention has been devised to eliminate the above-mentioned drawbacks and will be explained in detail below with reference to an embodiment shown in the drawings.

Reference numeral 11 denotes a spray nozzle that is fitted into the mist ridge of the humidifier main body (not shown), and has a flat discharge opening 13 that projects obliquely upward from one side of the cap-shaped nozzle main body 12.
A large number of minute grooves and grooves 14 and 15 are carved into the upper inner surface inclined part leading to the discharge port part 13.

The uneven strips 14 and 15 are designed to smoothly return the water droplets to the humidifier main body when the mist from the humidifier main body becomes water droplets and adheres to the upper inner slope of the discharge port 13. , it may be formed in a straight line as shown in FIG. 3, or it may be formed in a chevron shape that widens toward the discharge port 13 side as shown in FIG.

The pitch P (dimension from the bottom of a groove 14 to the bottom of the next groove 14 or from the top of a protrusion 15 to the top of the next convex 15) of the grooves 14 and 15 is 1wn.
Before and after is most effective.

As described above, according to the present invention, the upper inner surface slope of the discharge port of the nozzle and the uneven groove formed in the downward direction of the attached water droplets are formed with a pitch of about 1 inch. Water droplets adhering to the inner sloped portion can be returned to the humidifier body extremely smoothly.

In this case, the uneven grooves are carved in the direction of the flow of the water droplets that adhere, so they tend to adhere more smoothly than conventional nozzles in which the interior of the nozzle is roughened with chemicals or the like. Moisture can be returned into the humidifier body, and when spraying mist water, the grooves are aligned with the direction of the spray, so there is no increase in pipe resistance.
