no. 1 approach

[0037] A first embodiment of the present invention will be described. This embodiment, that is, the first embodiment, is the electrostatic spraying device 10 according to the present invention. This electrostatic spray device 10 is used to supply a makeup liquid to a user's face. The electrostatic spray device 10 is set at a position where droplets can reach the user only by the attraction force due to the electric field, and the electrostatic spray device 10 is used in this state.

[0038] like figure 1As shown, the electrostatic spray device 10 includes a box-shaped casing 11 whose front surface is arc-shaped. The housing 11 constitutes a main body portion, and includes a rectangular parallelepiped main portion 11a and a front surface portion 11b located on the front surface side of the main portion 11a. The side surface of the main part 11a is flush with the side surface of the front surface part 11b. The front surface of the front surface part 11b is formed in the shap...

[0062] A second embodiment of the present invention will be described. This embodiment, that is, the second embodiment, is the electrostatic spraying device 10 according to the present invention. As in the first embodiment, this electrostatic spray device 10 is used to supply cosmetic liquid to the user's face. As in the first embodiment, the electrostatic spray device 10 is used at a position where droplets can reach the user only by the attraction force due to the electric field. .

[0063] The electrostatic spray device 10 has a function of automatically adjusting the direction in which the spray nozzle 20 points. like Figure 5 As shown, the electrostatic spraying device 10 includes a drive unit 41 , an imaging unit 42 , a position calculation unit 43 , and an operation control unit 44 in addition to the configuration of the electrostatic spraying device in the modified example of the first embodiment. The position calculation unit 43 and the motion control unit 44 are...

Embodiment approach

[0086] The above-described embodiments may also be configured as follows.

[0087] The aforementioned embodiment may also be such that the liquid for dotting the eyes is used as the liquid sprayed in mist form. In this case, the electrostatic spray device 10 is used for the relief of dry eyes. The electrostatic spray device 10 is configured such that the spray volume when sprayed from the spray nozzle 20 is within the range of 0.1 μL or more and 1.0 μL or less per second, so that useful substances contained in tears and liquid adhering to the eyeball are not Drain together.

[0088] In addition, in the above-mentioned embodiment, the sprayed liquid may be a solution containing a component for protecting the mucous membrane of the throat.

[0089] In addition, in the above-mentioned embodiment, the electrostatic spray device 10 may be configured to be able to adjust not only the direction in which the spray nozzle 20 points in the vertical direction but also the direction in ...

Abstract

An electrostatic atomizer (10) includes a container part (15) for reserving a liquid containing a component useful for a human body, a nozzle part (20) communicated with the inside of the container part (15), and an electric field generation part (31) which generates an electric field at the tip of the nozzle part (20) when voltage is applied. By forming the electric field at the tip of the nozzlepart (20) by the electric field generation part (31), the liquid is atomized from the tip of the nozzle part (20). The direction of the nozzle part (20) is variable.

Description

technical field [0001] The present invention relates to an electrostatic spraying device that forms an electric field at a tip portion of a nozzle portion, thereby spraying liquid in a mist form from the tip portion of the nozzle portion. Background technique [0002] Electrostatic spraying devices that atomize and spray a liquid using electrohydrodynamics (EHD: Electro Hydrodynamics) have been known so far. Such an electrostatic spraying device is configured to generate an electric field at the tip of the nozzle, and to atomize and spray the liquid at the tip of the nozzle by utilizing the non-uniformity of the electric field. Patent Document 1 discloses such an electrostatic spraying device. [0003] Specifically, the electrostatic spray device of Patent Document 1 includes a solution tank, a spray nozzle, and a ring electrode. For example, an aqueous solution of an amino acid, theanine, is stored in the solution barrel. The spray nozzle communicates with the inner spac...
