Title: Beer dispenser

Description:
BACKGROUND OF THE INVENTION 
     The present invention relates to a novel beer dispenser and belongs to the field of beer production apparatus. 
     Beer is the oldest alcoholic beverage in human history. It ranks the third in terms of beverage consumption after water and tea. Beer was introduced to China in the early 20 th  century as an imported alcoholic beverage. The Chinese terminology for “beer” was derived from the English word “beer” and has been in use till now. The major ingredients of beers are barley malt, hops and water, which are fermented with yeast to brew a low alcoholic beverage with carbon dioxide. Some beers after opened have a poor mouthfeel especially in summer, yet there are few apparatus for improving beer mouthfeel in the marketplace. 
     BRIEF SUMMARY OF THE INVENTION 
     In view of the aforesaid disadvantages now present in the prior art, the present invention provides a novel beer dispenser. 
     To attain this, the present invention comprises a base, a main body and a cap. A receiving cavity is provided inside the main body. The receiving cavity accommodates a beer container. The main body is disposed on the base and has a bottom portion which communicates with the base. A base cup is provided inside the base. The base cup has a sealing flange on top. The base cup receives a bottom portion of the beer container. The main body has a top portion which is disposed with an air pump receiving cavity. An air pump is disposed inside the air pump receiving cavity. The cap is disposed at the top portion of the main body. A battery seat, a battery cap, batteries, a control PCB, a cathode spring plate and an ultrasonic oscillator are disposed inside the cap. The battery cap and the battery seat are disposed inside the cap at a top side and a bottom side thereof respectively. The cathode spring plate and the ultrasonic oscillator are disposed on the battery seat. The battery cap is provided with a battery receiving cavity. The batteries are disposed inside the battery receiving cavity. The control PCB is disposed between the battery cap and the battery seat. A beer faucet is provided at an outer side of the cap. A control handle is provided at an outer side of the beer faucet. A handle driving assembly is provided inside the beer faucet. An air valve assembly is provided at an inward facing end of the beer faucet. The handle driving assembly and the air valve assembly are connected with each other. 
     Preferably, the air valve assembly comprises an air valve switch, a silicone air valve, an air valve connecting member and a gas releasing spring. The air valve switch has a top portion which is connected to the handle driving assembly. The silicone air valve is disposed at a bottom portion of the air valve switch. The gas releasing spring is disposed at a bottom portion of the silicone air valve. The air valve connecting member passes through the silicone air valve and connects to the air valve switch. 
     Preferably, a beer hose is provided inside the main body. The beer hose has two ends which are respectively disposed inside the beer container and on an outward facing end of the beer faucet. 
     Preferably, the air pump receiving cavity has a bottom portion which is provided with a gas charging opening. 
     Preferably, a protective cap is provided at a top portion of the cap. An anode spring plate is disposed on a bottom portion of the protective cap. 
     Preferably, the base comprises a base casing and a silicone pad. A base cup receiving cavity for receiving the base cup is provided inside the base casing. The base cup receiving cavity extends from a top end to a bottom end of the base casing. The base cup is secured at a top end of the base cup receiving cavity by screws. The silicone pad seals a bottom end of the base cup receiving cavity. 
     The beneficial effects of the present invention are mainly as follows: 
     The present invention is divided into three parts, namely the base, the main body and the cap. Such reasonable structure facilitates both assembly and cleaning, improves mouthfeel of the beer stored inside. With the addition of the air valve assembly, the present invention ensures that the beer would not remain in the beer hose, thus eliminating any impact on subsequent dispensing of the beer.

     In the present invention, the base comprises a base casing  1  and a silicone pad  29 . The base casing  1  is provided with a base cup receiving cavity for receiving the base cup  6 . The base cup receiving cavity extends from a top end to a bottom end of the base casing. The base cup is secured at a top end of the base cup receiving cavity by screws. The silicone pad  29  seals a bottom end of the base cup receiving cavity. 
     Operating Principle: 
     First, the beer container  5  is positioned on the base cup  6 . The main body  2  is then connected to the base  1  and one end of the beer hose  25  is inserted into the beer container  5 . To dispense the beer, simultaneously activate the air pump  11  and the ultrasonic oscillator  15 . The air pump  11  pumps gas into the receiving cavity  4  to drive beer in the beer container to flow out from the beer hose  25 . The ultrasonic oscillator  15  performs high frequency oscillation to the beer flowing out from the beer hose  25  to foam the beer to improve mouthfeel. To stop dispensing the beer, simultaneously stop the air pump  11  and the ultrasonic oscillator  15 . The silicone air valve  22  moves upward by the force of the gas releasing spring  24  to discharge gas inside the receiving cavity  4 , thus preventing the beer from remaining in the beer hose  25 . 
     It should be noted that the above preferred embodiment does not limit the scope of the present invention. Although the present invention is described in detail in reference to the above embodiment, those skilled in the art may still make modifications or substitutions to the technical scheme as described in the above embodiment. Any modifications, substitutions, improvements and so forth not deviated from the spirit of the present invention fall within the scope of the present invention.
