     TECHNICAL FIELD 
       [0002]    The present invention relates to a technology of daily necessities, and particularly to a technology of a multi-functional wet wipe supply device. 
       BACKGROUND 
       [0003]    Compared with other wet wipes, facial tissues and towels, compressed wet wipe has four characteristics: 1) the material of wet wipe is pure natural plant fiber, which is more healthy to human body and more environment-friendly to the earth; 2) because of being made by compression, the compressed wet wipe has smaller volume than other wet wipes and towels and is more convenient to carry; 3) there will be a small amount of liquid when the wet wipe is used, and the liquid can be water, antiseptic solution or other dedicated liquid, so it is convenient to wipe off dirt and clean and sterilize the article being wiped; if dedicated liquid is used, some specific functions can be achieved further; 4) because of being made of nonbreakable plant fiber, the wet wipe will not be mashed when wiping an article with liquid on the surface, and can wipe the article clean more easily than facial tissues. 
         [0004]    However, when used, the compressed wet wipe needs to be taken out and put into a container first, and then wet wipe liquid is added into the container, so the operation is pure manual and relative troublesome. For the convenient use of the compressed wet wipe, a plurality of wet wipe preparing devices appear in the market. Each of these wet wipe preparing devices is mainly composed of a hand air pump, a wet wipe compartment, a dry wipe compartment and a liquid storage compartment, wherein the dry wipe compartment is used for storing dry wipes, and the liquid storage compartment is used for storing wet wipe liquid. When a wet wipe is to be prepared, a user can take out a dry wipe from the dry&#39;wipe compartment, put it into the wet wipe compartment, and then pump an appropriate amount of wet wipe liquid from the liquid storage compartment into the wet wipe compartment by the hand air pump to moisten the dry wipe in the wet wipe compartment. The defects of the existing wet wipe preparing devices lie in that: the user may cause secondary pollution to the residual dry wipes in the dry wipe compartment when taking out a dry wipe from the dry wipe compartment, so the devices are not suitable for use in public places; in addition, a relatively large operating force is needed when pumping the wet wipe liquid by the hand air pump, so the devices are inconvenient to use.

         [0056]    The method for using the first embodiment of the present invention is as follows: 
       1) Preparation of Wet Wipe 
       [0057]    Add wet wipe liquid to the liquid storage compartment through the liquid filling port, and position dry wipes in the wipe positioning holes; in initial condition, each wipe positioning hole is in alignment with each dry wipe detecting switch; if a dry wipe detecting switch detects that a dry wipe has been positioned in the wipe positioning hole right above it, it will output a “dry wipe” signal to the controller, otherwise, it will output a “no dry wipe” signal to the controller. 
         [0058]    When a wet wipe is to be prepared, the controller first controls the turnplate motor to operate and drive the turnplate to rotate in order to make a wipe positioning hole with a dry wipe in it reach a wet wipe preparing position, and this wipe positioning hole is considered as an objective wipe positioning hole. 
         [0059]    Then the wipe pushing rod is driven by the wipe pushing motor to slide outwards along the radial direction of the turnplate in order to: pass through the wipe pushing hole in the hole wall of the objective wipe positioning hole, push the dry wipe in the objective wipe positioning hole, and pass through the wipe outlet hole in the hole wall of the objective wipe positioning hole meanwhile, the dry wipe in the objective wipe positioning hole is pushed out of the wipe outlet hole by the wipe pushing rod; after the dry wipe is pushed by the wipe pushing rod to a position right above the compartment port of the wet wipe compartment, it falls into the wet wipe compartment; the wipe pushing rod is driven by the wipe pushing motor to slide radially inwards along the turnplate in order to retract to the objective wipe positioning hole. 
         [0060]    Finally, an appropriate amount of wet wipe liquid is pumped from the liquid storage compartment into the wet wipe compartment by the wet wipe liquid supply pump to moisten the dry wipe in the wet wipe compartment, and the preparation of a single wet wipe comes to an end. 
       2) Preparation of Ozone Water 
       [0061]    If ozone disinfecting water is to be prepared, connect the municipal water supply pipeline to the water inlet of the water inlet solenoid valve. When it is required to add water into the liquid storage compartment, the water inlet solenoid valve is opened, and running water in the municipal water supply pipeline can flow into the liquid storage compartment through the water inlet solenoid valve, water inlet check valve and ejector in sequence. 
         [0062]    If ozone drinking water is to be prepared, a purified water pump and a water filter bucket are also required. Connect the water outlet of the purified water pump to the water inlet of the water inlet solenoid valve, and connect the water inlet of the purified water pump into the cavity of the water filter bucket. When it is required to add water into the liquid storage compartment, the water inlet solenoid valve is opened, the purified water pump is started, and purified water in the purified water pump can flow into the liquid storage compartment through the purified water pump, water inlet solenoid valve, water inlet check valve and ejector in sequence. 
         [0063]    When it is required to supplement ozone into the liquid storage compartment, start the ozone generator and air booster pump, the ozone output valve is opened, and ozone generated by the ozone generator can be poured into the liquid storage compartment through the ozone check valve and ozone output valve and then respectively through the ejector and aeration stone. 
         [0064]    When it is required to use ozone water, control the ozone water outlet valve to be opened, and ozone water can flow out of the liquid storage compartment from the ozone water outlet valve. After the ozone water outlet pump is started, the output water pressure and flow of ozone water can be enhanced to rinse teeth and face. 
         [0065]    When it is required to heat the water in the liquid storage compartment, start the heater to prepare warm water and hot water.
