Description

  The present invention relates to a blower and a blower system that blow out charged particles together with air from a blower outlet.

  In the field of beauty such as improving human skin elasticity, various beauty instruments that irradiate charged particles around the skin have been proposed. In this beauty tool, charged particles are generated and released by a charged particle generator, and the human skin is irradiated with the charged particles. Irradiated charged particles have the effect of increasing the amount of moisture on the skin surface, and also have the effect of improving the skin elasticity by increasing the water retention in the deeper part of the skin (dermis).

As a method of generating charged particles, a method of generating positive and negative ions in which water molecules such as H ⁺ (H ₂ O) _m and O ₂ ⁻ (H ₂ O) _n are aggregated by discharging in air. It has been known. Here, m and n are arbitrary natural numbers. As another method for generating charged particles, mist-like charged water particles (hereinafter referred to as charged water particles) are obtained by applying a high voltage to water collected by condensation on a cooled electrode. There is also a method for generating the above. The effect of OH groups adhering to the skin surface due to irradiation of human particles with charged particles such as water-aggregated ions, charged water particles, etc. Is considered to occur.

  Patent Document 1 describes a negative ion generator improved for portable use. The negative ion generator includes a casing having an emission port, a negative ion generating electrode disposed inside the casing and generating negative ions as charged particles, and a negative high voltage applied to the negative ion generating electrode. A high-voltage board in which a high-voltage generating circuit to be applied is incorporated and a battery serving as a power source are provided. This negative ion generator is used by attaching an attachment means such as a string in the vicinity of the discharge port and hanging it around the lower face to release ions. In this state of use, the discharge port is located on the upper side of the casing, and negative ions discharged from the discharge port are irradiated to the face.

  The power supply switching circuit 31b receives power supply from the power supply unit 32, but supplies power from the external power supply 39 (voltage 5V) to the blower drive unit 35 because the external power supply 39 is connected to receive power supply. The blower drive unit 35 applies a voltage of 5 V to the motor 25b of the blower 25, and the blades 25a rotate to blow.

  The motor 25b of the blower 25 is, for example, a direct current motor, and the rotational speed increases when the applied voltage is high. The rotational speed when the blower 25 is operated by the external power source 39 is larger than the rotational speed when the blower 25 is operated by the battery 24.

The air flows into the outlets 12a and 12a through the flow path 27c, and positive and negative ions are generated by the ion generator 26 and discharged to the flow path 27c. The battery 24 supplies power to the blower 25 and the ion generator 26. When receiving power supply from the outside through the USB socket terminal 13b, the control unit 3 controls the blower 25 so as to increase the amount of air blown by the blower 25. Thereby, since the ventilation volume which blows from the air blower 100 can be increased, the speed of the airflow which blows off from the blower outlets 12a and 12a increases, and positive / negative ion reaches | attains further.

  Moreover, in this embodiment, the control part 3 has the power supply switching circuit 31b, and the power supply switching circuit 31b turns off the power supply from the battery 24 to the blower 25 when the USB socket terminal 13b receives the power supply. And since it switches to the electric power supply to the air blower 25 from the USB socket terminal 13b, the air flow volume by the air blower 25 can be made to increase automatically.

  Next, a state where the blower 100 is housed in the stand 101 and used will be described. FIG. 9 is a vertical side view of the stand 101 in a state where the blower 100 is accommodated. The container 50 of the cap 5 is lifted upward and removed from the base portion 4, the blower device 100 is inserted into the base portion 4 from above, and the lower end of the blower device 100 is fitted into the recess 43.

Is changed to be diagonally forward.

  Further, a conductive coating may be formed on the surface of the wind direction plate 62 facing the air outlet 12a, that is, the plate surface facing the front lower side of the wind direction plate 62. Since the ions blown from the blower 100 are blown to the wind direction plate 62, the wind direction plate 62 may be charged by the adhesion of the blown ions. When both positive ions and negative ions are generated by the ion generator 26, the conductive film formed on the wind direction plate 62 can neutralize the positive and negative charges and suppress the charging. When the ion generator 26 generates either positive ions or negative ions, positive and negative charges are supplied to the ground line by connecting the conductive coating to the ground line of the substrate 44.

Since the USB plug terminal 45 for supplying electric power is provided, the amount of air blown by the blower 25 can be increased while the blower device 100 is placed on the stand 101.

  Further, in the present embodiment, the stand 101 includes a wind direction plate 62, and the direction of the airflow blown out from the outlets 12a and 12a by the wind direction plate 62 is changed. Thereby, in the state which accommodated and installed the air blower 100 in the stand 101, the direction of the airflow which blows off from the blower outlets 12a and 12a of the air blower 100 changes, and can direct an airflow to a desired direction. For example, when the air blowing system (the air blower 100 and the stand 101) is placed on a table and used, positive and negative ions can be blown toward a human face. In addition, even if there is a distance between the air blowing system placed on the table and the human face, supplying the USB bus power to the air blowing device 100 increases the amount of air blown by the air blower 25, so that positive and negative ions travel further away. Can be reached.

  Further, in Embodiments 1 and 2, a mode in which ions in which water molecules are aggregated is generated as charged particles is shown. However, the present invention is not limited to this mode, and the blower device 100 does not charge charged particles such as charged water particles. The form to generate may be sufficient.
