A sterilizer for toothbrushes, puffs for cosmetic use and cosmetic brushes 100 according to the present invention includes a housing 10 that assumes the shape of a hexahedron and has a certain size of an opening in the upper portion of the housing and an internal storage space, a cover 20 that assumes the shape of a hexahedron and has an opening in the lower portion of the cover so that the cover is laid on and removed from the housing 10 from above and an internal storage space, a dehydrating sterilizer member 30 that assumes the shape of a hollow panel with a certain width and thickness and protrudes vertically upwards from the center of the bottom surface of the housing, a lower holder member 40 that includes a first lower holder member 41 that is a hexahedron, to be inserted into the housing 10, with the top surface is open and has a insertion tube 42 that extends upwards from the bottom surface of the first lower holder member 41 so that the dehydrating sterilizer member 30 is inserted from above to the bottom surface of the first lower holder member 41 and a second lower holder member 43, to be inserted into the first lower holder member 41, that has a insertion hole 44 in the center of the top surface to accept the dehydrating sterilizer member 30 and two or more hole cups 45 in either longitudinal side of the insertion hole 44 that are hollowed downwards to accept a toothbrush and cosmetic brush, an upper holder member 50 that is a plate the shape of which is identical to the top surface of the second lower holder member 43 and placed on the upper portion of the lower holder member 40, and a holder 60 that is inserted into a slit 35 formed in a side of the dehydrating sterilizer member 30, thereby holding a puff for cosmetic use.
The cover 20 may be required to be made of transparent synthetic resin in order to see through the inside of the sterilizer for toothbrushes, puffs for cosmetic use and cosmetic brushes 100.
The dehydrating sterilizer member 30 has on the surface a heat radiating plate 31 that has a certain width and spreads out on front and rear side of the dehydrating sterilizer member 30 down to the bottom surface of the housing 10 while a plurality of negative ion emitting perforations 32 that penetrate at an identical interval the surface of the dehydrating sterilizer member 30 and the heat radiating plate 31 so that the heat radiating plate 31 exerts heat and, simultaneously, the negative ion emitting perforations 32 that penetrate the heat radiating plate 31 discharge negative ions.
The dehydrating sterilizer member 30 is equipped in the inside with a PTC heater 33 (not illustrated) that heats the heat radiating plate 31 in order to maintain the heat radiating plate 31 at 40 to 45° C., a range of temperature one may not think very hot when he or she touches his or her hand on the heat radiating plate, and a negative ion generator 34 (not illustrated) that generates negative ions.
The first lower holder member 41 has in the internal wall, at a certain height, a protuberance and the second lower holder member 43 has in the rim of the top surface a stumbling block in order to assemble the second lower holder member 43 with the first lower holder member 41 while the second lower holder member 43 is mounted to and demounted from the first lower holder member 41.
The first lower holder member 41 is not integrated, to be a single unit, with but capable of being demounted from the second lower holder member 43 in order for the first lower holder member 41 and the second lower holder member 43 to be separated from each other, thereby being washed out with ease.
The hole cup 45 of the second lower holder member 43 as a hollow cylinder having the top and bottom ends open has threads on the external surface of the lower end while a hole cup bottom lid member 46 as a hollow cylinder having the top end open has threads on the internal surface of the upper end so that the hole cup 45 and the hole cup bottom lid member 46 are fastened to and unfastened from each other.
The hole cup 45 is not integrated, to be a single unit, with but capable of being unfastened from the hole cup bottom lid member 46 in order for the hole cup 45 and the hole cup bottom lid member 46 to be separated from each other, thereby being washed out with ease because it is not convenient to cleanse any scale, etc. formed on the bottom surface of the hole cup 45 when the hole cup 45 and the hole cup bottom lid member 46 are manufactured into a single unit although the hole cup 45 and the hole cup bottom lid member 46 that are manufactured separable from each other render each of the hole cup 45 and the hole cup bottom lid member 46 conveniently washed out.
The bottom surface of the hole cup bottom lid member 46 has a clearance between the bottom surface of the first lower holder member 41 and is slanted to a slight extent while the low end of the bottom surface of the hole cup bottom lid member 46 has a crack 47 to drain water.
Such a configuration of the hole cup bottom lid member 46 draws the water that drops from a toothbrush after use and puff for cosmetic use and cosmetic brush after wash down to the bottom surface of the first lower holder member 41, not pooling on the bottom surface of the hole cup bottom lid member 46.
Any water pooled on the bottom surface of the first lower holder member 41 may be readily evaporated because such water has a wide area that contact air and the heat radiating plate 31 extends down to the center of the bottom surface of the housing 10 although the water, dropping from a toothbrush after use and puff for cosmetic use and cosmetic brush after wash then flowing down to the bottom surface of the hole cup 45, that is pooled on the bottom surface of the hole cup bottom lid member 46 may cause microbial proliferation and fungi growth, etc. on the handle of those toothbrushes and cosmetic brushes that contact the pooled water.
The upper holder member 50 has in the center an upper insertion hole 51 into which the dehydrating sterilizer member 30 is inserted and in either longitudinal side two or more upper hole cups 52.
The lower holder member 40 is provided separately from the upper holder member 50 in order to first, install the lower holder member 40, thereby stably holding the lower portion of a toothbrush and cosmetic brush inside the hole cups 45 of the second lower holder member 43 because those toothbrushes and cosmetic brushes that are accepted upright in the upper hole cups 52 may not be held stably in the lower portion of the toothbrushes and makeup brushes when only the upper holder member 50 is installed without the lower holder member 40; second, pull the lower holder member 40 and upper holder member 50 out of the housing 10 just easily and manually for cleansing because it may not be convenient to wash out the hole cups 45, etc. when the lower holder member 40 and upper holder member 50 are integrated with each other into a single unit; and third, manufacture the upper holder member 50, which is what a user mostly observes when seeing through the cover 20 the inside of the sterilizer for toothbrushes, puffs for cosmetic use and cosmetic brushes 100, out of quality materials but the lower holder member 40 out of lower-priced materials, thereby lowering the production costs.
The holder 60 that is inserted into the slit 35 formed in a side of the dehydrating sterilizer member 30, thereby holding a puff for cosmetic use is pulled out of the slit 35 for washing out with ease.
It may be required that the cover 20 have two or more protrusions 21 (not illustrated) in the internal surface so that the negative ions emitted via the negative ion emitting perforations 32 collide with the protrusions on the internal surface of the cover 20, thereby being dispersed in various directions.
Meanwhile, the cover 20 has two or more air vents 22 in the top surface, where air flows, when the cover 20 is open, into the sterilizer for toothbrushes, puffs for cosmetic use and cosmetic brushes 100 is heated by the heat radiating plate 31 radiates and the heated air rises upwards to be discharged off the air vents 22 formed in the top surface of the cover 20, thereby generating an air flow that rises upwards from the lower portion of the sterilizer 100 then discharging, without an independently provided exhaust fan, the air that contains the moisture evaporated from the water drawn to and pooled on the bottom surface of the first lower holder member 41.
In general, a toothbrush is held, regardless of whether it is long or short, in the hole cup 45 and the upper hole cup 52, where the brush portion may face the heat radiating plate 31 and the negative ion emitting perforations 32, or not, when it is inserted in the hole cup 45 and the upper hole cup 52 without paying attention to direction.
Likewise, a puff for cosmetic use is held, in general, in the holder 60, where the face-touching surface of the puff for cosmetic use may face the heat radiating plate 31 and the negative ion emitting perforations 32, or not, when it is inserted in the holder 60 without paying attention to direction.
The heat radiating plate 31 has a certain width and spreads out on front and rear side of the dehydrating sterilizer 30 down to the bottom surface of the housing 10 while the plurality of negative ion emitting perforations 32 penetrate at an identical interval the heat radiating plate 31, which makes each toothbrush or cosmetic brush dehydrated and sterilized in an identical way regardless of its length.
Provided that a user neither brushes his or her teeth nor puts on makeup very frequently in a short period of time, each of those toothbrushes and puffs for cosmetic use that are exposed to the heat radiating plate 31 and the negative ion emitting perforations 32 is dehydrated and sterilized regardless of direction.
In particular, according to the present invention, unlike prior art, a user may be convenient because he or she needs not make sure that a toothbrush or puff for cosmetic use to be held faces the heat radiating plate 31 and the negative ion emitting perforations 32.
The sterilizer for toothbrushes, puffs for cosmetic use and cosmetic brushes 100 according to the present invention becomes ready to use by putting down the first lower holder member 41 from above and through the dehydrating sterilizer member 30 then plugging the first lower holder member 41 in the housing 10, inserting the second lower holder member 43 in the first lower holder member 41, placing the upper holder member 50 on the second lower holder member 43, inserting a toothbrush, puff for cosmetic use and cosmetic brush in the hole cup 45, the upper hole cup 52 and the holder 60 and finally covering the housing 10 with the cover 20.
A toothbrush, puff for cosmetic use and cosmetic brush that is held in the hole cup 43, upper hole cup 52 and holder 60, respectively, is dehydrated and sterilized by heating the heat radiating plate 41 with the PTC heater 33 and emitting negative ions via the negative ion emitting perforations 32 from the negative ion generator 34 when supplying electric power by making a power switch (not illustrated) of the sterilizer for toothbrush, puffs for cosmetic use and cosmetic brushes 100 according to the present invention.
For washing out the sterilizer for toothbrush, puffs for cosmetic use and cosmetic brushes 100 according to the present invention, a user may remove the cover 20 and pull out the upper holder member 50, second lower holder member 43 and first lower holder member 41 one after another then cleanse the members.
The sterilizer for toothbrush, puffs for cosmetic use and cosmetic brushes 100 according to the present invention may lower the production costs by dividing the lower holder member 40 from the upper holder member 50, thereby manufacturing the lower holder member 40 out of low-priced materials, omitting an independent toothbrush holder, etc. that would otherwise be installed for arranging the brush portion of a toothbrush in a predetermined direction, also omitting an exhaust fan that exhausts the air contained in the sterilizer for toothbrush, puffs for cosmetic use and cosmetic brushes 100, etc., which otherwise would increase the production costs and potentially incur failures in the exhaust fan, noise in operating the fan, electric power consumption to operate the fan, etc.
The sterilizer for toothbrush, puffs for cosmetic use and cosmetic brushes 100 according to the present invention may be problemproof and lower the production costs because the sterilizer for toothbrush, puffs for cosmetic use and cosmetic brushes 100 according to the present invention is operated only by making the power switch, without installing an independent control circuit that renders the device power-on by putting on the cover 20 and vice versa as found in common in prior art.
