Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to an improvement of the spray barrel of an ultrasonic humidifier (hereinafter simply referred to as a humidifier).

``Prior art'' Conventionally, in this type of humidifier, the spray port of the spray barrel was the fifth
The open socket type shown in the figure has a tapered cylindrical shape (not shown), so water droplets generated on the inside of the tip edge of the spray nozzle climb up the inside of the tip edge due to air blast from the fan, and eventually reach the tip edge. Overcome the
These water droplets may fall or be blown away, causing product quality deterioration or wetting floors and equipment. Especially in tea leaf storage systems that require increased humidity, these water droplets may adhere to tea leaves. and impair the luster of the color. Furthermore, in a mushroom cultivation system, these water droplets adhere to the mushrooms and cause a decline in quality, such as a white burn due to the so-called lens phenomenon. Furthermore, the floor surfaces become sticky, requiring time and effort to clean, and maintenance is difficult. Furthermore, the upper surfaces of the instruments become wet, which has a considerable negative effect on their lifespans.

``Problems to be Solved by the Invention'' Conventionally, there have been problems such as quality deterioration due to adhesion of water droplets that fall from the edge of the spray nozzle, and the floor surface getting wet. Therefore, the object of the present invention is to provide a spray barrel for a humidifier in which water droplets generated inside the tip edge are circulated back into the atomizing water tank even if they go over the tip edge by air blowing from a fan.

"Means for Solving the Problems" In order to solve the above problems, the present invention has the following configuration.

In other words, it is a spray cylinder having a slanted upward spray nozzle that is placed in an atomization water tank to which an ultrasonic vibrator is attached, and a slightly perpendicular direction on one side of the spray nozzle constituting this spray cylinder. To form a side that stands up.

Then, from slightly below the leading edge of this side part, there is a regulating bottom plate that extends slightly in a direction (approximately 90 degrees) intersecting this rising side, and a regulating bottom plate that extends from this regulating bottom plate in a direction perpendicular to the rising side (approximately 90 degrees) and said rising side. A weir plate is provided that slightly protrudes from the tip edge that is juxtaposed with the spray nozzle and that is in close proximity to the rising side of the spray nozzle.

Further, at least both sides of the regulating bottom plate are provided with through holes opened to communicate with the spray nozzle.

This is the structure of the spray barrel of an ultrasonic humidifier constructed by.

In particular, the present invention adopts the following configuration in order to prevent dripping from the slanted end side of the slanted spray port due to the fan blowing air from the tip edge of the slanted spray port.

That is, in order to generate water droplets inside the spray nozzle (near the weir plate, as described later), and to return the water droplets generated within the nozzle to the nozzle again, the spray tube is first constructed. A regulating bottom plate extends from slightly below the tip edge of one side of the spray nozzle in a direction intersecting this side to prevent steam from rising to that side.

The steam is then guided to a weir plate that slightly protrudes from the tip edge rising vertically from the regulation bottom plate and is provided close to the tip edge on one side of the spray nozzle. Most of the water droplets are generated near the leading edge of the plate.

The water droplets generated here fall onto the inner surface of the regulation bottom plate through the wind pressure of the fan, and the dropped water droplets (water) are passed through through holes opened on at least both sides of the regulation bottom plate so as to communicate with the spray ports. , which is configured to flow back to the spray nozzle.

"Embodiment" Hereinafter, one embodiment of the present invention will be specifically described based on the drawings.

1 is a humidifier main body comprising a fan 2 and an atomizing water tank 3, and 4 is an air passage. A spray cylinder 5, which will be described below, is removably placed in this atomization water tank 3. The spray cylinder 5 has a cylinder main body 5a which has a flat cylinder shape when viewed from above (see FIG. 3);
It consists of a spray port 5b that rises in an inclined manner from the cylinder main body 5a and converges (in FIG. 1, it rises upward to the right in the drawing).

One side of the spray nozzle 5b constituting this spray barrel 5 (one side on the right side when facing in the drawing in FIG. 1) is vertically aligned (in the left-right direction in the drawing in FIG. 3). One side that slightly rises 5
b' is formed over almost the entire width in the longitudinal direction.

From slightly below the leading edge 5c of this one side portion 5b', there is a regulating bottom plate 6a extending slightly in the direction (approximately 90 degrees) intersecting with this rising side portion 5b', and extending from this regulating bottom plate 6a in the vertical direction (approximately 90 degrees). ), a weir plate 6 is provided that slightly protrudes from the tip edge 5c that is juxtaposed with the rising side 5b' and is in close proximity to the rising side 5b' of the spray nozzle 5b. There is.

Further, the spray ports 5 are provided on both sides of the regulation bottom plate 6a.
A through hole 7 communicating with b is opened. In the figure, 8 is an ultrasonic transducer, and 9 is, for example, a cartridge type tank. The structure in which the spray barrels 5 are arranged in a series corresponding to the length in the left and right direction in the longitudinal direction of the atomization water tank 3 in FIG. Even if they are divided, they may have the same configuration.

"Function and Effect of the Invention" As described in detail above, the present invention has one side 5b' of the spray nozzle 5b of the spray barrel 5, and the control bottom plate 6a slightly extending from this one side 5b'. A spray cylinder of a humidifier having a structure in which a weir plate 6 is provided close to the tip edge 5c and slightly protrudes from the tip edge 5c, and several through holes 7 are provided in the regulation bottom plate 6a that communicate with the spray port 5b. 5, the steam rising from the cylinder body 5a of the spray cylinder 5 along the inner wall surface of the spray nozzle 5b and rising along the inner wall surface where the one side portion 5b' is provided is less than the one side portion 5b'. It is regulated by the outer wall surface of the regulation bottom plate 6a extending from the lower piece of the side part 5.
The rise of steam to b' is regulated (prevented).

In this way, the steam rising along the outer wall surface of the regulation bottom plate 6a is then transferred to the tip edge 5c, which rises vertically from the regulation bottom plate 6a.
One side 5 of the spray nozzle 5b that protrudes slightly more
The water is guided by the weir plate 6 provided close to b', and often becomes a water droplet B near the tip edge 6c of this weir plate 6.

The water droplets B generated here overcome the tip edge 6c of the weir plate 6 through the wind pressure from the fan, and
Most of the water droplets B are blown away and fall onto the inner surface of the regulating bottom plate 6a.

This is thought to be caused by the negative pressure between the weir plate 6 and the side portion 5b' and the weight of the water droplet B, which causes the water droplet B to be drawn in as shown by the arrow in FIG.

Then, the water droplet B that fell on the inner surface of the regulation bottom plate 6a
The water falls to the spray nozzle 5b through several through holes 7 formed in the regulation bottom plate 6a, and is ultimately returned to the spray nozzle 5b.

In addition, most of the water droplets B generated at the tip edge of the other side 5b'' of the spray nozzle 5b fall into the spray nozzle 5b, so there is no problem.Also, even if they are blown away by wind pressure, there is no problem. It seems that it is possible to catch water droplet B on plate 6.
After that, it is thought that the process will be similar to that described above. Therefore, unlike in the conventional case, the spray does not fall or be blown away outside the spray barrel 5, and it is possible to prevent quality deterioration and floor surfaces from getting wet. In addition, since the weir plate 6 is configured to slightly protrude from the tip edge 5c of the side 5b' of the spray nozzle 5, the water droplets B are drawn into the regulating bottom plate 6a due to the negative pressure phenomenon as described above, and the spray tube 5 It can prevent falling outside. Furthermore, it is economical because it can be installed in the conventional spray barrel 5, and has practical effects such as simple structure, less failure, and low-cost provision.
