Description

  The present invention relates to a spraying device that atomizes a liquid into fine mist by an ultrasonic oscillating means and sprays it in an atmosphere.

  Conventionally, humidifiers have been used when the air is dried in general residences or offices. Generally, an ultrasonic oscillator is installed inside and tap water is sprayed in a liquid tank. is there.

  In residences, hotels, sparrow houses, pachinko parlors, yakiniku restaurants, etc., there are many places where there is a need for antibacterial, anti-fungal and deodorizing in rooms. However, sprayers that are conventional humidifiers often have liquids ultrasonically oscillated from above the main body casing to form fine particles that are sprayed like steam and have a humidifying effect, but the particles are It is non-uniform and the spray efficiency is low.

Therefore, it is a method of deodorizing the odorous components in the atmosphere as having deodorizing means, and atomizing the deodorant aqueous solution that can deodorize the odorous components into the mist by ultrasonic oscillation. By applying an air stream carrying atomized mist by ultrasonic oscillation to the super particle selection plate arranged downward, coarse particle mist exceeding 3 microns is dropped by its own weight and removed from the air stream. There has been proposed an ultrafine particle mist of 3 microns or less selected from an atomized mist and blown into an atmosphere to be deodorized along with an air flow. (For example, see Patent Document 1)
By comprising in this way, the ultrafine particle mist bath of a deodorizing liquid is implement | achieved and a part elimination odor can be carried out, without making clothes and the inside of a room sticky.

  In addition, ultrasonic waves are applied to the hypozinc acid aqueous solution in the hypozinc acid aqueous solution reservoir by an ultrasonic vibrator, and fine particles of the hypozinc acid aqueous solution are generated in the fine particle generation unit. Is discharged from the spray port into the atmosphere, and at this time, the spray is transported and discharged far away on a transport flow sent from the spray port provided immediately below the spray port.

  In the sprayer disclosed in the above-mentioned patent document, water or a solution such as an antibacterial agent, antifungal agent, and deodorant is super mist of 3 microns or less, but super mist formation is incomplete. For example, in the illuminated sprayer disclosed in Cited Document 1, a fine particle selection cup is arranged above the ultrasonic wave transmitting means. The super particle selection cup has a large gap between the partition plate, and most of the air blown from the blower opening provided at the lower part of the partition plate is rotated or blown up horizontally. Without swirling in the cup, it is ejected in the horizontal direction or in the upward direction from between the superparticle selection cup and the partition plate. Therefore, the spray body ejected from the superparticle selection cup contains a lot of mist of 3 microns or more.

Spray bodies containing particles of 3 microns or more have large particle weight and high drop speed, and large particles adsorb super mist particles and fall. It is difficult to reach and it is difficult to obtain a high antibacterial effect, antifungal effect, and deodorant effect.
Furthermore, even if it is constructed so that it can be immersed in a fantastic world by illuminating the atomized body in color and viewing it from the window on the front surface of the main body casing, the spray body must contain particles of 3 microns or more. Therefore, a cloud with a desired color thickness cannot be formed due to reasons such as large particles adsorbing super mist particles and falling.
