Description

  The present invention relates to an ultraviolet sterilizer, and more particularly to a small ultraviolet sterilizer capable of sterilizing an object on which bacteria are propagated with ultraviolet rays.

  In general, when using tableware, baby bottles and other products, various pollutants and bacteria will propagate, and UV sterilizers that utilize ultraviolet rays are widely used as sterilizers that can remove them. Yes.

  In the case of such an ultraviolet sterilizer, most of the products have a form in which a product to be sterilized is stored inside the main body and then sterilized using ultraviolet rays irradiated through an ultraviolet lamp.

  However, in the case of such a stationary UV sterilizer, there are limits to the products that can be used. In other words, the stationary sterilizer can only sterilize products that can be stored inside the main body, such as tableware and baby bottles. There is a disadvantage that you can not.

  Therefore, in order to solve such disadvantages, portable ultraviolet sterilizers have been recently released.

  In the case of a portable ultraviolet sterilizer, it is common to form a reflective shade inside a main body on which a handle is formed, and to install an ultraviolet lamp inside the main body so that ultraviolet rays can be irradiated to the outside. This eliminates the need to store the product to be sterilized in the main body, and thus can be used for various purposes.

  However, even in the case of such a portable UV sterilizer, if the light emitted from the UV lamp is directly irradiated to the eyes of an adjacent person due to careless use, the eyes directly exposed to UV rays are adversely affected. There was a problem.

  In addition, the portable ultraviolet sterilizer has a disadvantage in that the user takes a handle and sterilizes the object for a predetermined time, so that the power is consumed and the convenience is inferior.

  The power switch 110 is electrically connected to the ultraviolet lamp 200 to turn the ultraviolet lamp 200 on / off.

  The tilt sensor senses the tilt of the main body 100 and controls on / off of the ultraviolet lamp 200 electrically connected according to a preset tilt value. Here, the setting of the inclination value may be a value fixed by the initial setting, and can be arbitrarily set by the user. However, in the case of arbitrary setting, a separate inclination setting is made on the upper surface of the main body 100. A button (not shown) is provided. The tilt sensor operates in conjunction with the power switch being turned on, and the operation is stopped in conjunction with the power switch 110 being turned off. The reason why the tilt sensor is provided is that if the human eye is directly exposed to ultraviolet rays from a predetermined distance, it may cause damage to the eyes. This is because the operation of the lamp 200 is stopped to prevent inadvertent damage to the eyes of a user or a nearby person.

  The tilt-off switch 120 prevents the tilt sensor from operating even when the power switch 110 is turned on. When the wall or an upright object is irradiated with ultraviolet rays, the ultraviolet lamp 200 is used. Therefore, when the operation of the inclination sensor is interlocked with the power switch 110, the operation of the ultraviolet lamp 200 is not performed by the inclination sensor, and this is to be prevented. is there. Of course, if there is a tilt setting button, the tilt off switch 120 can be replaced simply by adjusting the irradiation angle of the ultraviolet rays, so if there is a tilt setting button, the tilt off switch 120 can be omitted. Of course, both the tilt-off switch 120 and the tilt setting button can be provided.

  The control unit controls an electrical connection relationship among the power switch 110, the tilt sensor, the tilt-off switch 120, and the ultraviolet lamp 200. Of course, if there is a tilt setting button, the electrical connection relationship with this button is also controlled.
