Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an ultrasonic atomizing device that removes large droplets and ejects only fine droplets.

[0002]

[Prior art]

 Conventionally, as this type of mist ultrasonic atomizer, as shown in FIG. 3, an ultrasonic vibrator 2 is attached to the lower part of a liquid tank 1, and an oscillator circuit 3 is connected to the ultrasonic vibrator 2 to A liquid supply device 4 is connected to the body tank 1, and a blower port 6 to which a blower device 7 is connected is provided above the surface of the liquid 5 in the liquid tank 1, and further, a case 8 at the upper part of the liquid tank 1 An ultrasonic atomizing device in which a liquid level meter 10 is installed in the liquid tank 1 is also proposed.

[0003]

[Problems to be solved by the device]

 By the way, in such an ultrasonic atomizer, when the liquid body 5 is supplied to the liquid tank 1 from the liquid supply device 4, the ultrasonic wave generated from the ultrasonic vibrator 2 forms the liquid column 11, The liquid torn from the liquid column 11 becomes mist-like small droplets and is generated in the case 8, and the atomized liquid is forcibly forced from the jet port 9 of the case 8 by the air sent from the blower 7. Erupted.

However, in this ultrasonic atomizer, the droplets generated in the case 8 include not only small droplets but also large-sized droplets, and these droplets are both blown by the blowing device 7. The small droplets are mixed into the air when ejected because they are forcibly ejected by the air from, but the large droplets are immediately attached to the surrounding objects and become liquid. Therefore, there was a problem that the surroundings became wet with a liquid.

[0005]

[Means for Solving the Problems]

 According to the present invention, a liquid is supplied from a liquid supply device to a liquid tank at a constant level, an ultrasonic vibrator is attached to the liquid tank, and an oscillation signal is applied from an oscillating circuit. In an ultrasonic atomizer that generates more ultrasonic waves to atomize the liquid, an air intake port formed above the liquid surface and the ultrasonic waves generated by the ultrasonic transducer cause the liquid column to It is composed of a fan that is rotated by a motor that is mounted on the upper part and a jet port that is formed on the upper part of the case.

[0006]

[Action]

 In the present invention, as the fan rotates above the liquid column formed by the ultrasonic waves generated from the ultrasonic transducer, the liquid droplets torn from the liquid column are lifted by the air that has entered from the blower port. , Sent around Juan.

When the surrounding air and droplets spirally swirl due to the rotation of the fan, among the droplets sent to the periphery of the fan, the droplets of relatively large size are rotated inside the case by the rotation of the fan. It becomes liquid and returns to the liquid tank, and only small droplets are ejected from the ejection port of the case.

As described above, since only fine droplets are ejected from the liquid ejection port of the case, the surroundings are not wet with the droplets.

【Example】

 FIG. 1 is a sectional view of an ultrasonic atomizing device according to an embodiment of the present invention, in which 1 is a liquid tank, 2 is an ultrasonic vibrator, 3 is an oscillation circuit, 4 is a liquid supply device, 5 is a liquid, and 10 is a liquid. The level meter 11 is a liquid column, and the configuration thereof is the same as that of the above-mentioned conventional example. Therefore, the description is omitted, but in this example, the air intake port 12 is provided above the liquid surface of the liquid tank 1. Further, the motor 15 is supported by the supporting portion 14 on the case 13 above the liquid column 11 generated from the liquid tank 1, and the fan 16 is fixed to the rotation shaft of the motor 15, and the upper portion of the motor 15 is further fixed. The case 13 is bent so that the ejection port 13a is provided.

In this embodiment having such a configuration, when the liquid 5 is supplied from the liquid supply device 4 to the liquid tank 1 and the oscillation signal is output from the oscillation circuit 3 to the ultrasonic transducer 2, the liquid column 1 1 is generated and the droplet is torn from the liquid column 11, but when the fan 16 is rotated by the motor 15 and air is sent from the air intake port 12, a small droplet floating around the liquid column 11 is generated. And large droplets are sent around the fan 16.

Here, as the fan 16 rotates, the sent air swirls, so that a large droplet hits the case 13 to become a liquid and is returned to the liquid tank 1 through the wall of the case 13. Only fine droplets are ejected from the ejection port 13a.

In the present embodiment, since the large droplets are removed by swirling the air by the fan 16 in this way, only fine droplets are ejected from the ejection port 13a of the case 13, and therefore, There is an advantage that the surroundings do not get wet due to the droplets.

FIG. 2 is a sectional view of an ultrasonic atomizing device according to another embodiment of the present invention, in which 1 is a liquid tank, 2 is an ultrasonic vibrator, 3 is an oscillation circuit, 4 is a liquid supply device, and 5 is a liquid supply device. Liquid, 10 is a level meter, 11 is a liquid column, 12 is an air intake port 13 is a case, 14 is a support part, 15 is a motor, and 16 is a fan. These configurations are the same as those in the above-mentioned embodiment. Although description is omitted, in this embodiment, a cap 17 having a closed top is attached to the upper part of the liquid column 11 generated from the liquid tank 1 to the upper part, and ventilation is provided between the periphery of the cap 17 and the case 13. A passage 18 is formed.

In this embodiment having such a configuration, when the liquid 5 is supplied from the liquid supply device 4 to the liquid tank 1 and the oscillation signal is output from the oscillation circuit 3 to the ultrasonic transducer 2, the liquid column 1 1 is generated and the liquid droplet is torn off from the liquid column 11, but since the cap 17 is provided on the upper portion of the liquid column 11, large particles of the droplet hit the cap 17 to become liquid and are returned to the liquid tank 1.

When the fan 16 is rotated by the motor 15 so that air is taken in and sent from the port 12, only small droplets floating around the liquid column 11 are caught between the case 13 and the cap 17. The air is passed from the ventilation passage 18 around the fan 16.

Here, since the fan 16 rotates, the sent air swirls, so that among the smaller droplets, a large droplet hits the case 13 and becomes a liquid, which causes the wall of the case 13 to fall. It is transmitted and returned to the liquid tank 1, and only fine droplets are ejected from the ejection port 13 a.

In this embodiment, the cap 17 removes large droplets, and the fan 16 swirls the air to remove relatively large droplets among small droplets. Only fine droplets are ejected from the ejection port 13a of the case 13, so that there is an advantage that the periphery is not wet by the droplets.

[0018]

[Effect of device]

 As described above, in the ultrasonic atomizing device of the present invention, by swirling the air by the fan above the liquid column generated by the ultrasonic waves, relatively large droplets are removed among small droplets, Since only fine droplets are ejected from the ejection port of the case, there is an advantage that the surrounding area is not wet with liquid and the fine liquid is mixed in the air. The advantage is that small droplets can be removed after removing.
