Title: Egg beater

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This invention relates to an egg beater, particularly to one able to evenly beat egg liquid conveniently and quickly. 
     2. Description of the Prior Art 
     Conventionally, to beat an egg, firstly, it is usual to prepare a container and knock the eggshell against a hard object to deposit the egg liquid in the container, and then beat the egg liquid in the container with chopsticks. However, beaten with chopsticks, egg liquid can hardly be beaten completely and evenly. Hand egg beaters and electric egg beaters sold on the market can solve such a problem. A conventional hand egg beater  1 , as shown in  FIG. 1 , is to have egg liquid deposited in a container  11 , and then hold the container  11  with one hand and grasp the egg beater  1  with the other to beat the egg liquid  10  in the container  11  vortically. Although the conventional hand egg beater  1  can evenly beat the egg liquid, yet it will take much time and labor to finish such work, and in the course of beating egg liquid, the egg liquid  10  is likely to be slashed out of the container  11  in case of applying force improperly or excessively. A conventional electric egg beater can beat egg liquid with less time and labor indeed, but during beating egg liquid, the egg liquid still may be splashed out of a container, and if the electric egg beater is used for beating only one egg at one time, it will squander away energy source, thus not conforming to economic gain. 
     SUMMARY OF THE INVENTION 
     The objective of this invention is to offer an egg beater able to evenly beat egg liquid conveniently and quickly. 
     The egg beater in the present invention includes a base, a stirrer, a waterproof washer and an upper cover. The base is formed with an accommodating chamber having a positioning projection fixed therein and has the upper edge of its outer wall disposed with an engage groove having its lower side bored with an annular recess. The stirrer is installed in the center of the accommodating chamber of the base, having its upper side provided with a whisking member and its underside bored with an insert groove. The waterproof washer is fitted around the engage groove of the base, and the upper cover is mounted on the base and has its inner wall bored with an annular recess at its bottom.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     A preferred embodiment of an egg beater in the present invention, as shown in  FIG. 2 , includes a base  2 , a stirrer  3 , a waterproof washer  4  and an upper cover  5  combined together. 
     The base  2  is formed with an accommodating chamber  20  fixed therein with a positioning post  21  having its outer wall oppositely provided with tangent planes  210 . The base  2  further has the upper edge of its outer wall bored with an engage groove  22  having its lower side disposed with an annular recess  23 . 
     The stirrer  3  firmly installed in the accommodating chamber  20  of the base  2  has its upper side provided with a branch-leave-shaped whisking member  30  and its underside bored with an insert groove  31  having its inner wall oppositely provided with tangent planes  310 . 
     The waterproof washer  4  is fitted around the engage groove  22  of the base  2 . 
     The upper cover  5  is preferably semispherically-shaped, to be mounted on the base  2 , having its inner wall disposed with an annular recess  50 . 
     In assembling, referring to  FIGS. 2 and 3 , firstly, the stirrer  3  is installed in the accommodating chamber  20  of the base  2 , letting the positioning post  21  in the accommodating chamber  20  inserted in the insert groove  31  in the underside of the stirrer  3 . Restricted by mutual engagement of the tangent planes  210  on the outer wall of the positioning post  21  and the tangent planes  310  on the inner wall of the insert groove  31 , the stirrer  3  can stably and immovably be positioned in the accommodating chamber  20 . Next, the waterproof washer  4  is fitted around the engage groove  22  of the base  2 , and then the upper cover  5  is covered on the annular recess  23  of the base  2 , letting the waterproof washer  4  closely fixed between the annular recess  50  of the upper cover  5  and the engage groove  22  of the base  2 , thus finishing assembly of the egg beater. 
     In using, referring to  FIGS. 3 and 4 , firstly, remove the upper cover  5  from the base  2  and knock an egg  6  against the whisking member  30  of the stirrer  3  to break the eggshell and let the egg liquid  60  flow into the accommodating chamber  20  of the base  2 . Subsequently, fix the upper cover  5  on the base  2  to let the waterproof washer  4  closely positioned between the annular recess  50  of the upper cover  5  and the engage groove  22  of the base  2 . Then, hold the base  2  and the upper cover  5  with hands and repeatedly shake the whole egg beater in directions up and down or left and right to let the egg liquid  60  in the accommodating chamber  20  of the base  2  thoroughly whisked by the leaves-shaped stirrer  3  in the accommodating chamber  20 . At this time, the waterproof washer  4  closely fixed between the upper cover  5  and the base  2  will function to prevent the egg liquid from seeping out of the jointed portion of the upper cover  5  and the base  2 . After the egg beater is shaken completely, remove the upper cover  5  from the base  2  and the egg liquid  60  evenly whisked can be poured out for use from the accommodating chamber  20  of the base  2 . By so designing, the egg beater of this invention can effectively prevent egg liquid  60  from splashing out of the base  2  when the egg liquid is whisked, able to quickly and evenly whisk eggs with less labor. 
     While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
