Description

[Detailed Description of the Invention] This invention relates to a hand mixer that is driven by dry batteries.

All conventional hand mixers require an AC power source, and their bulk and weight make them inconvenient to handle.

In order to eliminate such drawbacks, the present invention relates to a small and lightweight hand mixer that is powered by dry batteries (two AA batteries in the example), and is suitable for use in places without AC power, in real life, in laboratories, or at home. It can be easily used in a cooking room, etc.

Examples will be described below.

Fig. 1 shows an external view of the hand mixer with the stirring shaft extended, and Fig. 2 shows a new view of the fir 1.

The case 1 has a built-in small DC motor 2 and a plurality of dry batteries 3, and is shaped so that it can be held in hand. Fig. 1 shows an example using two AA batteries, but depending on the stirring capacity, multiple AA batteries can be used. , uses AA batteries.

The case 1 has a threaded part 4 in the center, and can be divided into two parts, a front part and a rear part, when installing a dry battery.

5 is a spring contact that contacts the electrode of the dry battery 3; 6 is a compression coil spring that presses the dry battery and electrically connects it; and 7 is a push button switch.

Further, reference numeral 13 indicates wiring for connecting the dry battery and the DC motor, and reference numeral 8 indicates a conical rubber coupling, which is attached to the motor shaft.The conical portion is fitted into the conical hole of the drive shaft 9 to rotate the stirring shaft.

10 is a ball bearing that supports the drive shaft;
2 is an extendable stirring shaft having two blade stirring blades 11 at its tip.

Now, if you extend the stirring shaft 12 as shown in Figure 2 and press the push button switch 7, the spring 5 will come into contact with the battery's pole and close the electric circuit, so the DC motor will rotate and the rubber coupling will close. The stirring shaft and stirring blades are rotated to perform the required stirring.

Since the stirrer main body is small and lightweight, the stirrer can be held by simply grasping the dry cell part of the case with one hand.

When stirring is to be stopped, when the push button switch 7 is released, the compression coil 6 is extended, the spring 5 is automatically separated from the electrode, and the DC motor is stopped.

The length of the stirring shaft is sequentially reduced, and the stirring blades are contracted into the case.

The present invention is a small and lightweight hand mixer that is powered by a dry cell battery, so it provides extremely convenient convenience for stirring liquids in small containers in places without AC power, in laboratories, home cooking rooms, etc. It is.
