     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The present invention of a vertically working liquid vaporizer, referring to FIG. 1, mainly comprises a cup body ( 1 ) with a standing post ( 2 ) disposed at the center thereof and an encircling dam ( 11 ) situates in between to define a receiving container ( 12 ); a heat generator ( 3 ) of a ceramic-made electric resistance of positive temperature coefficient is mounted downwardly from the said standing post ( 2 ); two sides of the said generator ( 3 ) are conducted to the electric source through a conducting tab and a conducting cord ( 30 ); the outside of the said generator ( 3 ) is covered by a lay of heat conducting and insulating film ( 33 ) and is inserted into the interior of the standing post ( 2 ) through a C-shaped press element ( 31 ); after the insertion, the said generator ( 3 ) presses in an uni-direction towards the internal surface of the standing post ( 2 ) to relatively achieve a pressing heat conduction effect; with a sufficient surface range inside the cup body ( 1 ), a plurality of the said standing posts ( 2 ) can be disposed to form a plurality of heat resources. 
     Referring to FIG. 2, the external surface of the said generator ( 3 ) is covered by a lay of heat conducting and insulating film ( 33 ); the resilient function of the upward side wings ( 311 ) of the press element ( 31 ) squeeze and press toward the back side of the said generator ( 3 ) to affix it with a pressing force oppositely to the flat internal surface of the said standing post ( 2 ) and to transmit the heat generated therefrom more completely. 
     Referring to FIG. 3, the said generator ( 30 ) is housed inside the said standing post ( 2 ), pressed by the press element ( 31 ) and conducted to the electricity through the conducting cord ( 30 ); the top end opening of the said standing post ( 2 ) is sealed; as to the entire cup body ( 1 ), the said generator ( 3 ) can achieve a completely waterproof effect and internally heat the water liquid inside; during the heating procedure, as long as any height of the upper surface film of the water liquid touches the circumferential bordering line defined by any height position on the outer circular surface of the standing post ( 2 ), the portion adjacent to the upper surface bordering area of the said standing post ( 2 ) will partially form film-line shape to be vaporized rapidly due to the direct heating from the said generator ( 3 ); therefore, to view it vertically, the water liquid of the water surface at any water position adjacent to the area bordered with the said standing post ( 2 ), is rapidly effected by the said generator ( 3 ) to generate steam right away and that tremendously shortens the waiting time for steam generation; of course, the predetermined high/low heat effect of the generator ( 3 ) can achieve the desirable amount of vaporization. 
     The generator ( 3 ) is comprised by a ceramic-made electric resistance of a positive temperature coefficient, therefore it possesses heat conducting effect; when it is close to the heat source on one side of the press element ( 31 ), the air blocking effect of the space existing between the said press element ( 31 ) and the standing post ( 2 ) disables the high temperature on the opposite side of the said generator ( 3 ) to be rapidly conveyed outwards, only the temperature generated at the position of the flat plane ( 20 ) of the standing post ( 2 ) can be rapidly conveyed therefrom; since the said generator ( 3 ) possesses the heat transmitting effect, it conveys the related temperature on one side of the press element ( 31 ) toward the other end to form a transmitting effect of temperature supplement so that the said heat source can be conveyed toward one side of the flat plane ( 20 ) as much as possible. 
     Referring to FIG. 4, when the present vaporizer is applied to a facial steamer for cleansing the skin, mainly a guiding mask ( 4 ) is used to gather steam to dispense toward the face but not the two sides; no matter how much water is poured in, as long as a the water position, as shown in FIG. 3, reaches any height position inside the longitudinal height of the said standing post ( 2 ), the said generator ( 3 ), as shown in FIG. 3, can rapidly generate high temperature after being conducted to the electricity by the on/off switch ( 51 ) disposed on the machine body ( 5 ) and directly heat and vaporize the film-line bordering line formed on the topmost surface film of the liquid directly; therefore, once the on/off switch ( 51 ) is connected, the embodiment of the present invention can rapidly obtain steam generation; of course, after a certain period of heating time, the cupful liquid will be boiled due to the heat transmission of the liquid itself. 
     Referring to FIG. 5, the upward position of the surface range of the receiving container ( 12 ) disposed inside the cup body ( 1 ) can hold a dripping device ( 6 ); basically, the dripping device ( 6 ) is a water tank body ( 60 ) with a water inlet ( 61 ) disposed in the upper aspect; a tube opening ( 62 ) drains the water drop and a adjusting valve ( 63 ) adjusts the dripping speed; thereby, the dripping water is adjusted in speed to drip into the receiving container ( 12 ) or even to the upper surface of the standing post ( 2 ); the micro amount of water supplement in drops efficiently eliminates the prior temperature elevation time for more water liquid and rapidly evaporate the water drop at a micro second. 
     Referring to FIG. 6, the generator ( 3 ) disposed inside the said cup body ( 1 ) can be in the form of stacked generators ( 7 ); similarly positioned inside the standing post ( 2 ), a plurality of ceramic-made electric resistant tabs ( 71 ) of positive temperature coefficient are comprised in a stack; the bottom portion of the entirety is pressed, supported and positioned by a press plate ( 73 ) and conducted to electricity through a plurality of optional and individual electric source conducting cords ( 72 ); thereby more heat generating electric resistant tabs can be installed to obtain more power rate or optional applications at multiple power rates. 
     Referring to FIG. 7, if the space inside the standing post ( 2 ) is sufficiently enough, not only the area of the ceramic-made electric resistant tabs can be enlarged, they can be cut into a plurality of electric resistant tabs ( 711 ,  712 ) supported by a bottom plate ( 710 ) to comprise multiple tabs on one plane; by different connections, a plurality of electric cords ( 713 ) can be conducted synchronously or individually to obtain optional applications at different power rates, relatively at different temperature or working efficacies to meet various application requirements. 
     It is of course to be understood that the embodiment described herein is merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
