Description

The present invention relates to an electrostatic atomizer suitable for the purpose of containing chemical substances used in daily life, such as fragrances, pharmaceuticals, bactericides, and deodorants, in a mist and releasing them.

As an example of the chemical substance, a conventional technique and problems thereof will be described with respect to a device that emits a mist containing a fragrance.

In today's stressful environment, devices that release fragrances in mists are attracting attention as products that give people healing. As a liquid atomization system, an ultrasonic system that vibrates a liquid at high speed using ultrasonic waves, pulverizes and discharges the liquid is widely used. As conventional examples, there are JP-A-2003-245580, actual climbing 3100873, and the like.

However, if the ultrasonic vibrator driven at high frequency is not used in a state where it is filled with a liquid, there is a problem that the ultrasonic wave is reflected inside the element, generates heat, and deteriorates or breaks. Becomes complicated.

Recently, an electrostatic atomization method has attracted attention as a method that is simple in structure and suitable for atomizing a small amount of liquid. Various devices have been developed for the purpose of spraying liquid paint. As conventional examples, there are JP-A-2004-361909, JP-A-2005-164139, and the like.

However, no device has been developed for the purpose of containing and releasing chemical substances used in daily life, such as fragrances and pharmaceuticals, in the mist. For example, it is possible to atomize and release a fragrance-containing liquid using a conventional electrostatic spraying device, but since the mist is emitted at a wide opening angle, there is a problem that it is difficult to control the mist emission direction. .

When considering application to an aroma device, it is not necessary that the fragrance-containing mist is simply released, but it is desirable that the mist emission is visually beautiful. In addition, it is more desirable to be able to control the mist emission direction and the emission speed because the scent can be presented as the user likes.

Since the mist is emitted straight from the tip of the tube, or the mist is emitted as if it is flying as a mass, it has a beautiful and visual healing effect .

By using the fog transport cylinder (T3), a heating means can be provided on the upper part of the cylinder. Since a heat rising airflow is generated in the cylinder, the effect of discharging the mist straight is great. The appearance of the fog rising from the tube is reminiscent of incense smoke and has a high healing effect. When the fragrance-containing liquid is atomized, the scent spreads like an incense stick and stimulates the sense of smell, giving a physiological and psychological healing effect. Since the olfactory stimulus and the visual stimulus are given, the healing effect is high due to the synergistic action .

Due to the electric field generated during this period, the cylinder moves in the axial direction at high speed and is emitted .

Since it becomes difficult for the mist to collide with the wall of the cylinder, a lot of mist can be emitted, which is efficient. Moreover, fog is conveyed in a long cylinder without using an airflow generator such as a fan. By bending the tube, mist can be conveyed and released in various directions. Since the fog transport cylinder and the electrode can be integrated, the number of parts is small and economical . In addition, as shown in FIG. 4, by providing a plurality of adjustment electrodes (T52, T53, T54, T55) on the upper part of the mist carrying cylinder (T5), various electric fields (T51) can be formed between the counter electrode (T51).

If it controls so that it may inject in a conveyance cylinder , fog will be discharge | released from the front-end | tip of the said cylinder as a cyclic | annular mass. The annular fog has a characteristic of flying in the air while rotating by creating a vortex in the circumferential direction of the longitudinal section of the ring. Since the mist flies without spreading, the mist can be presented to a user at a remote location. When a fragrance is contained in a mist and released, the scent can be presented pinpointly .

<Effects of Means 5>

FIG. 1 is a first embodiment of the present invention, and is characterized in that a mist generated by the force of an electric field is applied between an ejection electrode and a counter electrode in the axial direction of a mist carrying cylinder. It is an electrostatic atomizer. FIG. 4A is a view of the longitudinal section of the apparatus viewed from the side, FIG. 4B is an external view of the capillary type liquid jet tube T1, and FIG. 3C is an external view of the tube diameter change type liquid jet tube T2. FIG. 4D is an external view of the counter electrode T31, and FIG. 4E is an external view of the adjustment electrodes T32 and T33.

With reference to FIG. 1A, the structure and operation of this apparatus will be described. It is assumed that the lower end of the capillary-type liquid injection tube T1 is connected to a container for storing the fragrance-containing liquid Wa (not shown in the figure), and the liquid surface reaches the upper portion of the tube by capillary action. The upper part of T1 constitutes the ejection electrode T11. A high voltage is applied to the electrode by a DC power source EE1. G is ground, and Sw is a switch.

T3 is a mist carrying cylinder for receiving fine particles emitted from the injection tube T1 and carrying the fine particles in the same scattering direction, and a counter electrode T31 is provided on the lower T3A. T31 has a ring shape and is provided so as to surround the fog transport cylinder. A strong electric field E1 can be generated between T11 and T31. When the fragrance-containing liquid in the liquid jet tube is charged, the liquid at the tip of the tube is torn off by the force of the electric field to become fine particles ma, that is, atomized and enters the mist transport tube.

Adjustment electrodes T32 and T33 for transporting the fog ma in the axial direction T3AX of the cylinder are provided on the abdomen T3B and the upper part T3C of the fog transport cylinder T3. EE2 and EE3 are DC power supplies. E2 is an electric field generated between T31 and T32, and E3 is an electric field generated between T32 and T33. The mist is transported to the mist transport cylinder upper portion T3C by the electric fields E2, E3.

Here, at the time of the atomization, a droplet liquid AK2 having a large particle diameter is also generated. The droplet liquid collides with the wall of the cylinder and falls, and is collected in the fragrance-containing liquid reservoir.

A cylinder heating means HT is connected to the upper part T3C of the fog transport cylinder T3. The HT includes a heat diffusion filler 89 provided with a number of air holes Air and a moisture-resistant heating element YAS.

When the air hole of the thermal diffusion filler 89 constituting the heating means HT is enlarged to reduce the air resistance and the operation of the switch Sw is switched between OFF, ON, and OFF, a pulsed voltage is applied to the ejection electrode, Since the atomization is performed instantaneously when it is ON, the fog moves in the mist transport pipe T3 upward at a high speed. Since the atmospheric pressure in the cylinder is instantaneously increased by the fog, the fog is instantaneously discharged from the tip T3E of the fog discharge cylinder 80 to fly as an annular fog Lm. Since Lm flies without breaking the predetermined distance shape, it is visually interesting and has a healing effect.

Further, liquid jet tubes T1 and T1b are provided in 20 and 20b. The liquid Wa is filled up to the tip of the injection tube by capillary action.

As shown in FIG. 1, by applying a high voltage, the liquid Wa is sprayed into the mist transport tube T3 from the tip of T1 to become a mist ma. The fog travels in the tube by an electric field and is emitted from the tip of the fog discharge cylinder 80. At the time of the jetting, the droplet liquid AK2 that has not become mist falls from the lower part of the mist transport cylinder T3 and is collected in the small liquid container 20.

Reference numeral 70 denotes a wing type airflow generating means. When operated, air enters the upper housing 04 from the air hole Air, and the atmospheric pressure in the housing increases.
