Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an atomizing device for atomizing a very small amount of liquid.

[0002]

BACKGROUND ART Conventionally, as an atomizing device for atomizing a liquid, an ultrasonic atomizing device using a piezoelectric element is known. The ultrasonic atomizer is, for example, a water tank containing a liquid,
A vibrating body provided on the bottom surface of the water tank and having a piezoelectric element is provided. Such an ultrasonic atomization device vibrates the vibrating body by applying an AC voltage to the piezoelectric element of the vibrating body, and atomizes the liquid in the water tank with ultrasonic waves from the vibrating body.

[0003]

By the way, there are cases where it is desired to atomize a small amount of liquid, such as an aromatic agent and a deodorant used indoors. In this case, in the ultrasonic atomization device described above, since vibration energy is applied to the liquid through the water tank, the vibration energy is dissipated, and even if an attempt is made to atomize a small amount of liquid, a lot of power is consumed and the efficiency is reduced. It was falling.

An object of the present invention is to provide an atomizing device capable of efficiently atomizing a trace amount of liquid.

[0005]

In order to achieve the above object, the atomizing device of the present invention adopts the following constitution. That is, the atomizing device of the present invention includes a vibrating body including a piezoelectric element, a supply device that supplies a liquid to the vibrating body, and the vibrating body by applying a voltage to the piezoelectric element of the vibrating body. An applying device for vibrating the
It is characterized by being supported by one fulcrum.

According to the present invention, the liquid is supplied to the vibrating body by the supply device, and an AC voltage is applied to the vibrating body, whereby the piezoelectric element constituting the vibrating body repeatedly expands and contracts, and the entire vibrating body Vibrates and the liquid atomizes. At this time, since the vibrating body is supported by one fulcrum, it is possible to reduce the vibration energy transmitted from the vibrating body to other parts through the fulcrum as much as possible. Therefore, even if the vibrating body is vibrated at a low voltage, most of the vibration energy generated in the vibrating body can be added to the liquid, so that the liquid can be easily atomized, that is, atomized, and vibrated through the water tank as in the past. Compared to the case where energy is applied to the liquid, a small amount of liquid can be atomized more efficiently, and the conventional emptying prevention device becomes unnecessary.

In the atomizing device of the present invention, it is preferable that the fulcrum of the vibrating body is a portion corresponding to a node of a vibration mode. According to this invention, in the vibration mode of the vibrating body,
Since the vibrating body is supported by the portion corresponding to the node, that is, the portion that does not vibrate at all, it is possible to further reduce the vibration energy transmitted from the vibrating body to other parts through the fulcrum, and to atomize a small amount of liquid more efficiently.

In the atomizing device of the present invention, it is preferable that the vibrating body has a beam shape. According to this invention, since the vibrating body has a beam shape, that is, a shape that is short in the width direction and long in the length direction, the vibrating body is located at a position apart from the fulcrum by a predetermined distance in the length direction, for example, the largest amplitude. By supplying the liquid to the portion, vibrational energy can be easily applied to the liquid. That is, even if the length of the vibrating body in the width direction is shortened, the liquid can be easily atomized, so that the atomization device can be downsized.

In the atomizing device of the present invention, it is preferable that the vibrating body is in the form of a rectangular flat plate having long sides and short sides, and is supported by the long side portions. According to this invention,
Since the vibration mode having sufficient amplitude can be generated in the long side direction while ensuring the rigidity of the vibrating body in the short side direction, the liquid can be reliably atomized.

In the atomizing device of the present invention, the piezoelectric element is
It is desirable that it is provided on one of the front and back surfaces of the vibrating body. According to the present invention, since the thickness of the vibrating body can be reduced, the atomization device can be downsized.

It is desirable that the liquid can be directly supplied to the vibrating body. According to the present invention, even if the vibrating body is slightly vibrated at a low voltage, the vibration energy can be directly applied to the liquid, so that there is no energy loss and the heat generated by the vibration can be added to the liquid. A small amount of liquid can be efficiently atomized.

In the atomizing device of the present invention, it is preferable that a portion of the vibrating body to which the liquid is supplied is treated to prevent the liquid from flowing. According to the present invention, for example, by applying a treatment to the liquid to make it difficult to wet the liquid and holding the liquid in a droplet form, the liquid flows from the surface of the vibration body from the time when the liquid is supplied to the vibration body until the atomization. Since this can be prevented, the liquid can be reliably atomized.

In the atomizing device of the present invention, it is desirable that the liquid is any one of a fragrance, a deodorant, and a chemical. According to the present invention, the effect can be achieved by atomizing a small amount of liquid.

In the atomizing device of the present invention, the supplying device is
An elastically deformable tube that contains the liquid and has a tip disposed at a position where the liquid can be discharged in a droplet form onto the vibrating body, a base portion provided with the tube, and a plurality of balls A retainer having a ball holding portion that holds the ball rollably thereon, a pressing member that presses the ball against the tube to close a portion of the tube, and a drive mechanism that moves the pressing member along the tube. It is desirable to have and. According to the present invention, by driving the pressing member along the tube by the drive mechanism, the ball is pushed by the pressing member while being held by the retainer and rolls on the tube, and a fixed amount of liquid per fixed time is reached. Can be reliably supplied to the vibrating body from the tip of the tube.

In the atomizing device of the present invention, the drive mechanism is
The pressing member is configured to include the vibrating body that is in contact with the pressing member on the distal end side in the length direction, and the applying device that can adjust the applied voltage. It is desirable that the member can be continuously moved and the liquid ejected in a droplet form on the vibrating body can be atomized. According to this invention, since the vibrating body that atomizes the liquid is used as the drive mechanism that drives the pressing member, it is possible to easily switch between driving the pressing member and atomizing the liquid simply by adjusting the application frequency of the applying device. be able to.
Therefore, a separate drive source is not required to drive the pressing member, so that power saving can be achieved.

In the atomizing device of the present invention, it is desirable that the base end of the tube is connected to a tank containing the liquid. According to the present invention, since the liquid can be always supplied to the tube by the tank, the liquid can be surely supplied to the vibrating body.

The piezoelectric element 122 provided in No. 1 repeatedly expands and contracts to vibrate the entire vibrating body 12 and atomize the liquid. At this time, since the vibrating body 12 is supported by the arm portion 13 as one fulcrum, it is possible to reduce the vibration energy transmitted from the vibrating body 12 to other parts via the arm portion 13 as much as possible. Therefore, even if the vibrating body 12 is vibrated at a low voltage, most of the vibration energy generated in the vibrating body 12 can be added to the liquid, so that the liquid can be easily atomized, that is, atomized, and the conventional water tank can be used. Compared with the case where the vibration energy is applied to the liquid through, a small amount of liquid can be atomized more efficiently, and the conventional emptying prevention device is unnecessary.

(2) In the vibration mode of the vibrating body 12,

Since the vibration mode of the liquid can be generated, the liquid can be surely atomized.

(5) Since the piezoelectric element 122 is provided on one of the front and back surfaces of the vibrating body 12, the thickness of the vibrating body 12 can be reduced, and the atomizing device 10 can be miniaturized.

(6) Since the liquid is directly supplied to the vibrating body 12 by the liquid ejecting apparatus 1, even if the vibrating body 12 is slightly vibrated at a low voltage, the vibrating energy can be directly applied to the liquid, resulting in energy loss. In addition, the heat generated by the vibration can be added to the liquid, and a small amount of the liquid can be efficiently atomized.

(7) On the lower side of the reinforcing plate 121 of the vibrating body 12, in order to prevent the liquid from flowing, a treatment for making the liquid difficult to wet and holding it in the form of drops is applied over the entire surface. Therefore, it is possible to prevent the liquid from flowing from the surface of the vibrating body 12 between the time when the liquid is supplied to the reinforcing plate 121 and the time when the liquid is atomized, so that the liquid can be reliably atomized.
