The present invention relates to a charging and sterilizing rack for a razor, and specifically, an ultraviolet sterilizing unit capable of irradiating ultraviolet rays on the shaving surface of the razor is installed inside the upper head for sterilization of the charging and sterilizing rack, or An alcohol spray unit for sterilization and disinfection of the shaving surface is installed to sterilize the shaving surface of the razor, and the height of the upper head is adjusted according to the height of the vertical length of the razor, which is the object to be sterilized, so that the sterilization of the shaving surface is efficiently performed. It is to do.

Recently, a sterilizing stand for razors with a sterilizing function that allows the use of a razor hygienically by sterilizing the shaving surface of a razor for facial shaving with an ultraviolet light-emitting diode has been proposed in Utility Model Registration No. 20-0464328.

This prior art is excellent in the convenience of performing the sterilization function by sterilizing the shaving surface of the razor, but the razor is sterilized by opening the cover of the sterilization cradle body placed on the floor, inserting the razor, and closing the cover. Therefore, the opening and closing operation of the cover for mounting the razor is cumbersome, and the sterilizing portion of the main body has a concave inlet portion, and thus, a problem that foreign matter enters the concave inlet portion may be pointed out.

According to the present invention, the shaving surface of the razor is sterilized by spraying the sterilizing disinfectant to the shaving surface of the razor while allowing the razor to be mounted to perform charging and at the same time to sterilize the shaving surface of the razor by means of an ultraviolet light emitting diode. Make it a technical task.

In addition, the present invention makes it easy to sterilize the shaving surface by adjusting the height of the upper head for sterilization according to the height of the vertical length of the razor so that the shaving surface of the razor is close to the upper head. Make it a technical task.

The present invention is a charging and sterilizing rack consisting of a charging box having an insertion portion that allows a lower portion of the handle of the razor to be inserted and erected, and a pillar that combines the rear of the charging box and the rear of the upper head for sterilization treatment, the charging and sterilizing rack An ultraviolet sterilization unit is installed on the inner side of the upper head, and the pillars of the charging and sterilization cradle are separated into upper and lower pillars, and a plurality of height adjustment protrusions protruding at regular intervals from the front surface of the upper pillar are inside the lower pillar. It is characterized in that it is configured to adjust the height of the upper head of the charging and sterilizing holder in response to the height of the vertical length of the razor by forming a height adjustment portion to be caught in the plurality of locking grooves concave at predetermined intervals on the side.

In addition, the present invention is a filling and sterilization cradle comprising a filling box having an insertion portion that allows the lower part of the handle of the razor to be inserted and erected, and a pillar that combines the rear of the filling box and the rear of the upper head for sterilization treatment, the filling and sterilization An alcohol spraying unit for sterilization and disinfection is installed on the inner side of the upper head of the holder, and the pillars of the sterilization holder are separated into upper and lower pillars and combined. It is characterized in that it is configured to adjust the height of the upper head of the charging and sterilizing holder in response to the height of the vertical length of the razor by forming a height adjustment part that engages the locking grooves that are concave at predetermined intervals on the inner side of the lower pillar. .

When the present invention is applied to an electric razor, it is easy to mount the razor by inserting the lower part of the handle of the razor into the insertion part, and the razor can be charged while the razor is upright, and ultraviolet rays can be efficiently irradiated to the shaving surface of the razor. By doing so, it has the effect of enhancing the sterilizing function of the shaving surface.

In addition, the present invention improves the sterilization function of the shaving surface by automatically spraying the sterilizing disinfectant solution onto the shaving surface of the razor at a predetermined time.

In addition, in the sterilization treatment of the shaving surface of the razor, the present invention can maximize the convenience of use and sterilization efficiency by allowing the use of ultraviolet sterilization and sterilization with an alcohol disinfectant, either alone or in parallel.
