The present invention relates to an odor removal device, and more particularly, to an odor removal device to come into contact with an object so as to activate surrounding materials according to a dielectric barrier discharge principle.
bromhidrosis (body odor) refers to an odor caused by fatty organic matter secreted through sweat and bacteria. Currently, chemical compound deodorants are used to remove the odors for cosmetic and etiquette purposes.
However, controversy over the harmfulness to the human body due to the deodorants for suppressing bromhidrosis is increasing. In particular, the harmfulness of contained chemical ingredients for blocking pores to suppress the secretion of sweat has been raised. In addition to simple dermatitis, breast cancer, deterioration of thyroid functions (triclosan), abnormal sweat secretion hormones due to obstructed sweat glands (aluminum salt), skin damages, and hyperpigmentation may be caused.
Accordingly, there is a need for odor removal technology capable of suppressing the bromhidrosis without the harmfulness of chemical ingredients.
The present invention provides an odor removal device capable of suppressing the bromhidrosis without using chemical ingredients.
The present invention provides an odor removal device capable of activating surrounding materials with high energy.
The odor removal device according to the present invention includes: a case; an activation device installed in the case and coming into contact with an object to activate surrounding materials according to a dielectric barrier discharge principle, wherein the activation device may include: a dielectric having an outer surface exposed to an outside and provided as a curved surface; and an electrode positioned inside the dielectric in which power is applied to the electrode.
In addition, the dielectric may have a predetermined thickness, and have an inner surface facing the outer surface, wherein the outer surface of the electrode may include a contact area that comes into contact with the inner surface of the dielectric, and a non-contact area that does not come into contact with the inner surface of the dielectric.
In addition, the non-contact area may be positioned in a central area of the outer surface of the electrode, and the contact area may surround the non-contact area.
In addition, the non-contact area may have a circular or oval shape.
In addition, the contact area may be provided with a plurality of contact areas, spaced apart from each other with the non-contact area therebetween.
In addition, the odor removal device may include an odor sensing unit installed in the case, and coming into contact with the object to detect an odor.
According to the present invention, organic matter may be removed and bacteria may be killed from the skin by using active species, so that odor-causing factors can be removed.
According to the present invention, the non-contact area of the electrode and the dielectric may be positioned at a contact point between the dielectric and the object, so that a current leakage can be minimized, and streamer with high energy may be generated along the boundary of the contact area between the electrode and the dielectric, so that the surrounding materials can be activated with high energy.

The activation device 102 may be installed on an upper end of the case 101. The activation device 102 comes into contact with the object 20 to generate active species according to the dielectric barrier discharge principle. The activation device 102 includes a dielectric 110, an electrode 120.
The dielectric 110 has a predetermined thickness, and has an inner surface 111 and an outer surface 112.

According to one example, the outer surface 121 of the electrode 120 may be formed with a hole or a groove 122 recessed inward to the electrode 120. The area formed with the hole or groove 122 is provided as the non-contact area A2 that does not come into contact with the inner surface 111 of the dielectric 110. The hole or groove 122 may have the same diameter toward an inner side of the electrode 120. On the contrary, the hole or groove 122 may have the diameter gradually decreased toward the inner side of the electrode 120.
The power is applied to the electrode 120 while a partial area of the dielectric 110 is in contact with the object 20. Due to the application of power, a streamer is generated along a periphery of the contact point between the dielectric 110 and the object 20. The streamer activates surrounding materials such as air. During the activation, active species, electrons, and ions are generated, ultraviolet rays and visible rays are emitted, and an electromagnetic field is generated.
Meanwhile, in the electrode 120, a current leakage occurs toward the object 20 from an area that is close to the object 20. The current leakage occurs at the contact point between the dielectric 110 and the object 20, in which the amount of current leakage is increased as a distance between the electrode 120 and the contact point is decreased.
The present invention the non-contact area A2 is formed on the outer surface of the electrode 120 at a position corresponding to the contact point, so that the occurrence of the current leakage is minimized. Specifically, the dielectric 110 has the central area mainly coming into contact with the object 20, in which the non-contact region A2 of the electrode 120 is positioned in the central area of the dielectric 110. Accordingly, the current leakage to the central area of the dielectric 110 is minimized, and a high energy streamer is generated around the contact area boundary between the dielectric 110 and the object 20, so that the surrounding material can be activated with high energy.
