1. A toothbrush case comprising a lower case having a projection portion for projecting at a given height (T) on a supporting surface, an ultraviolet radiation means supported by the supporting surface in the lower case, a receiving member having a portion for receiving a toothbrush in order to sanitize said toothbrush with ultraviolet light radiated by the ultraviolet radiation means, an ultraviolet discharging outlet, and an upper case being hinge coupled with the lower case for opening and closing the receiving member, the toothbrush case further comprising:a spaced supporting portion being provided on a lower surface of the supporting surface in the lower case and being projected at the given height (T) so that ground moisture does not contact with the supporting surface and that outside air flows into a bottom of the supporting surface when the lower case is placed on the ground;a lower air flow path being formed on the supporting surface in the lower case so that outside air flows into an inside of the lower case through a space created by the spaced supporting portion;an air flow path provided between the ultraviolet radiation means and an ultraviolet discharging outlet of the receiving member so that outside air flows through the lower air flow path into a sealing space between the receiving member and the upper case, andan upper airflow path provided on the upper case so that outside air flows through the upper case into the receiving member having the air flow path. 2. A toothbrush case according to claim 1 wherein the receiving member comprises a photocatalyst in order to cause a strong oxidation-reduction reaction for environmental organic material, and to eliminate bad smells, bacterium, and mold. 3. A toothbrush case according to claim 1 wherein a spaced projection portion is formed in front of the UV discharging outlet of the receiving member to sanitize bacteria penetrated into a bristle by using UV light radiated through the outlet. 4. A toothbrush case according to claim 1 wherein the upper airflow path is positioned in opposing position with a bristle of the toothbrush to prevent dust from flowing into the bristle. 5. A toothbrush case according to claim 2, wherein the photocatalyst is TiO2. 6. An UV sanitizing toothbrush case for sanitizing a toothbrush by UV radiation comprising;a lower case having a spaced supporting portion formed on a lower surface of a supporting surface, and a portion for projecting on the surface at a given height (T), the surface is provided with a lower air flow path, thus flowing in air through the lower air flow path formed by the spaced supporting portion;a receiving member having a receiving portion being engaged with the lower case for receiving the toothbrush and having an UV discharging outlet, the member is sprayed and coated with photocatalyst to cause strong oxidation-reduction reaction for environmental organic material in order to eliminate bad smells, bacteria, and mold;an upper case having an upper air flow path thereon, for hinge-coupling with the lower case to close the receiving member after the toothbrush is received in the receiving portion of the receiving member; andan UV radiation means provided between the receiving member and the lower case for radiating UV light to the toothbrush for sterilization by UV and for turning on a UV lamp promptly in a power saving mode in case that the upper case is closed. 7. An UV sanitizing toothbrush case according to claim 6 wherein the UV radiation means includes:a lamp made of a transparent crystal material having high transmissivity, and sealed with gas mixed with inert gas;a first and a second W filament coils provided on both ends of the lamp and covered with BaO2 thereon so that hot electrons can be emitted easily from mixed gas in the lamp;a condenser made of high conductive material, wherein one end of the condenser is coupled to the second W filament coil, and the other end of the condenser is coupled to the top of the first W filament coil in order to emit hot electron gas even if a low voltage is applied to the first and the second W filament coil; anda control member for controlling hot electron emission and UV light radiation by the condenser under the low voltage. 8. An UV sanitizing toothbrush case according to claim 7 wherein if the low voltage is applied initially to the toothbrush case under control of the control member, the voltage is applied to the condenser, one end of the condenser being coupled to the second W filament coil, and the other end of the condenser being coupled to the top of the first W filament coil so that UV light is emitted from the lamp by discharging the mixed gas between the condenser member and the first W filament coil. 9. An UV sanitizing toothbrush case according to claim 7 wherein in order to sanitize the toothbrush effectively by UV radiated from the lamp, the control member comprises a sensor for detecting when the toothbrush is positioned in the toothbrush case and the upper case is closed;a power supply for providing power responsive to a sense signal of the sensor;a controlling portion for controlling power supplied from the power supply in the power saving mode; anda voltage output for outputting regular voltage to the W filament coils so that the voltages supplied from the power supply responsive to a control signal of the controlling portion output at rating voltage. 10. An UV sanitizing toothbrush case according to claim 9 wherein the control member can operate with an operation acknowledgement execution mode for turning on the lamp for one minute then turning it off in order to know whether the lamp operates correctly or not, and a power saving acknowledgement mode for turning on the lamp three minutes per hour in the power saving mode after the operation acknowledgement mode is executed in order to radiate UV effectively. 11. A toothbrush case according to claim 6, wherein the photocatalyst is an ABS resin.
