[0026] Refer to the following Figures 1-6 A portable blender according to some embodiments of the present application is described.

[0027] A portable mixer comprises a cup 1, a blade holder 2 and a mixer base 3, the cup 1 is detachably connected with the blade holder 2, and the blade holder 2 is detachably connected with the base 3. Since the three parts are independently detachable, they are easy to be disassembled and cleaned after use.

[0028] The cup 1 is open at both ends, the upper end is narrowed and connected with a cup cap 4 by screwing, and the lower end cup wall is also provided with threads for connecting with the blade holder 2.

[0029] The blade holder 2 comprises a blade disc 5, a rotating shaft 6 and a driven seat 7. The blade disc 5 is provided with a first through hole 8 and a third protrusion 9, and is sleeved with a first sealing ring 10 provided with a fourth protrusion 11 and a hollow sleeve 12 in opposite directions. The fourth protrusion 11 is downward and just passes through the first through hole 8 of the blade disc 5, and the hollow sleeve 12 is upward and is embeddedly connected with the third protrusion 9 of the blade disc 5. The middle part of the blade disc 5 is upwardly recessed and extended to form a mounting cavity 13, and the top of the mounting cavity 13 is provided with a second through hole 14. The driven seat 7 is tightly embedded at the entrance of the mounting cavity 13. The edge of the blade disc 5 is turned up to form a cylindrical wall 23, and the cylindrical wall 23 is provided with long strip protrusions distributed in a spiral direction for screwing connection with the threads of the cup. The rotating shaft 6 is embedded in the mounting cavity 13 of the middle part of the blade disc 5, the upper end of the rotating shaft 6 is extended from the second through hole 14 of the top of the mounting cavity 13, and is connected with a stirring blade 15, and the lower end of the rotating shaft 6 is connected with the driven seat 7 by screwing. Such connection mode makes the blade holder 2 simple in structure and firm in whole. The bottom of the mounting cavity 13 is provided with a second protrusion 21, and the second protrusion 21 is clampedly connected with a screw buckle 24 on the mixer base 3.

[0030] The base 4 comprises a casing 16, a driving device 17 driving the blade 15, a safety switch 18 and a base 19 at the bottom of the base, the output of the driving device 17 goes out of the casing 16 and is provided with a driving seat 20. The upper end of the driving seat 20 is provided with a recess and is connected with the fifth protrusion 22 at the lower end of the driven seat 7.
