FIG. 2 is a schematic cross-sectional view cut along line II-II shown in FIG. 1.

Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings. However, the spirit of the present invention is not limited to such an embodiment, and the spirit of the present invention may be proposed differently by addition, change and deletion of components constituting the embodiment, but this is also included in the spirit of the invention. It becomes.

Referring to FIG. 1, a droplet spraying device 1 according to a preferred embodiment of the present invention includes a body portion 10, a droplet generating portion 20, a flow guide portion 30, and a spraying portion 40.

For reference, the droplet spraying device 1 described in the present invention is a device capable of spraying droplets into the air for humidification, control, quarantine, sterilization, disinfection, and antibacterial, and the like, in this embodiment, an ultrasonic humidifier as an example Explain.

The body portion 10 accommodates the fluid F. Here, the fluid F is illustrated as including general water. In addition, the body portion 10 has a shape in which the cross-sectional area gradually decreases from the liquid level of the fluid F to the droplet generating portion 20 to be described later, as shown in FIG. 2. That is, the body portion 10 has a shape in which the cross-sectional area decreases toward the floor, as shown in FIG. 2. For reference, in this embodiment, it is exemplified that the body portion 10 has a pipe shape having a curvature.

The droplet generating unit 20 is immersed in the fluid F inside the body 10 to generate droplets from the fluid F. In the present embodiment, the droplet generator 20 may be illustrated as a method of generating droplets D by granulating the fluid F by ultrasonic vibration, but is not limited thereto. That is, any of the various droplet (D) generation principles, such as a heating method in which the droplet generating unit 20 generates droplets from the fluid F by heating or a centrifugal spray method in which the fluid F is split into small particles using centrifugal force. It is natural that one can be employed.

On the other hand, the droplet generating portion 20 is in a state immersed in the bottom of the body portion 10. Accordingly, the cross-sectional area of the body portion 10 from the liquid level of the fluid F to the droplet generation portion 20 is gradually reduced, so that the fluid F contained in the body portion 10 is completely consumed for the generation of the droplet D. You will be able to. That is, compared to the conventional structure in which the bottom of the body portion 10 is flat, it is possible to maintain a state in which the droplet generating portion 20 is always immersed in the fluid F. As a result, the area where the fluid F is not used for the generation of the droplet D, that is, the dead volume of the fluid F is not caused, and the fluid F accommodated in the body 10 is the droplet D ) Can be used for all occurrences.

The flow induction part 30 induces the flow of the fluid F within the body part 10. In this embodiment, it is exemplified that the flow induction part 30 is provided on one side of the body part 10 and includes a fan 31 for generating a flow of air W. In addition, the flow induction unit 30 includes a pipe (hereinafter referred to as a “flow induction pipe”) 32 connected through and connected to one side of the body 10, as shown in FIG. 1. For this reason, it is preferable that the flow guide unit 30 has a structure in which the fan 31 is mounted on the flow guide pipe 32.

The curvature of at least a part of the flow guide pipe 32 of the flow guide unit 30 exceeds zero. That is, the flow induction part 30 is exemplified as having a shape in which the whole or part of the flow guide has a curvature, and in this embodiment, the whole has a curvature and thus has a tubular shape having a circular cross section.

The spraying portion 40 sprays the droplets D generated from the droplet generating portion 20 to the outside of the body portion 10. This spraying portion 40 includes a tube (hereinafter referred to as a spraying tube) 41 formed through the other side of the body portion 10 facing the flow induction portion 30, and the droplets D are air (W ) To the outside of the body 10 according to the flow.

The sprinkling pipe 41 of the sprinkling portion 40 also, like the flow guiding pipe 32 of the flow guiding portion 30, at least partly has a shape having a curvature, and in this embodiment, the entire cross section has a curvature. It is illustrated as being.

On the other hand, as shown in FIG. 1, the angle θ1 from the flow guide pipe 32 of the flow guide unit 30 to a point horizontal to the droplet generating unit 20 is an acute angle less than 90°. In addition, the angle θ2 from the spraying pipe 41 of the spraying portion 40 to the horizontal point with the droplet generating portion 20 is also an acute angle of less than 90°.

Due to this configuration, the air (W) guided through the flow guide unit (30) flows in an inclined downward direction toward the droplet generating unit (20) to support the droplet (D) generated from the fluid (F). Thereafter, the flow of air (W) is switched in an upward direction by a repulsive force between the flow of air (W) continuously introduced through the flow induction unit 30 and the level of the fluid (F), so that the air (W) It will be sprayed through the spraying pipe 41 of the spraying unit 40. Accordingly, it is possible to guide the droplet (D) toward the spraying portion 40 side without resistance to the flow of the fluid (F) to be discharged to the outside.

In addition, at least a partial expansion angle (θ3) of the flow guide pipe 32 of the flow guide unit 30 and at least a partial expansion angle (θ4) of the spray pipe 41 of the spray unit 40 are 45° or more and 135° or less. to be. With this configuration, it is possible to prevent condensation of the droplets D in the flow guide pipe 32 of the flow guide part 30 and the spray pipe 41 of the spray part 40.

Meanwhile, in this embodiment, as shown in FIG. 1, the upper and lower angles of at least a partial expansion angle (θ3) of the flow guide pipe 32 are the same, and at least a partial expansion angle (θ4) of the spray pipe 41 The upper and lower angles are also illustrated and illustrated as the same, but are not limited thereto. That is, the angles of θ3 and θ4 shown in FIG. 1 are not limited to the illustrated angles, and the upper and lower angles of the expansion angle θ3 of the flow guide pipe 32 and the expansion angle θ4 of the spray pipe 41 It is natural that different variations are possible within the angular range of 45° or more and 135° or less.

The droplet spraying operation of the droplet spraying apparatus 1 according to the present invention having the above configuration will be described with reference to FIG. 1 as follows.

First, the fluid F is accommodated in the body portion 10, and the droplet generating portion 20 is immersed in the inner bottom of the body portion 10. The droplet generating unit 20 generates droplets D from the fluid F using the principle of generating droplets D such as ultrasonic vibration. The generated droplets D are discharged to the outside through the spraying unit 40 according to the flow of the air W introduced by the flow guide unit 30.

At this time, as the angles (θ1) (θ2) to the point horizontal to the droplet generation unit 20 and the droplet generation unit 20 are each acute angle less than 90°, respectively, the flow guide unit 30 The air () introduced through it can be smoothly discharged to the spraying unit 40 together with the droplets (D) without resistance to the flow of the fluid (F).

In addition, the expansion angles (θ3 and θ4) of the flow guide pipe 32 of the flow guide part 30 and the spray pipe 41 of the spray part 40 are respectively 45° or more and are provided to be inclined to 135° or less. , By reducing the occurrence of condensation inside the pipe, efficient discharge of the droplet (D) becomes possible.
