Milk foam machine directly driven by motor

Abstract

The invention discloses a milk foam machine directly driven by a motor, comprising a cup cover, a cup body, an inner cup, a stirrer, a control panel, an electric heating tube, a motor and a power supply base. The milk foam machine adopts a sleeved structure that an upper piece and a lower piece of an electric connector are respectively arranged below the cup bottom and on the power supply base; and after the upper piece is sleeved with the lower piece, an external power supply in the power supply base is connected with a circuit below the cup to supply power for the electric heating tube and the motor. An aluminum sheet is compounded on the electric heating tube; the motor is arranged below the cup through a motor fixed piece; a driving shaft of the motor passes through the cup bottom from the eccentric position and extends into a container; a stirrer for stirring or foaming is sleeved at the shaft end; a sealing ring with more than two rings of flange rings is arranged between the driving shaft and a shaft hole; the flange ring of an inner ring is protruded into a high lug boss for sealing the shaft hole and the shaft; and the flange ring of an outer ring is used for sealing the surface space between the cup bottom and the fixed sheet. The invention has the advantages of favorable sealing performance, simple structure, favorable foaming effect and stable heating. The milk foam machine is applicable for heating or not heating and foaming or only heating liquid state milk.

Description

technical field [0001] The present invention relates to an appliance for preparing liquid foam from milk-based liquid, in particular to a household appliance for heating or not heating, stirring or frothing milk-based liquid. Background technique [0002] A milk frother is an electric appliance that froths milk. Since it involves heating and stirring the milk, both an electric heating device and a rotating stirring device are required. Milk is a food with high hygiene requirements. The existing heating method uses indirect heating. The heating element in it is not in direct contact with the milk, and it needs to be easy and reliable to control without overheating; it is more difficult to handle. The most important thing is the stirring method. The general anchor or paddle stirrer only plays the role of stirring, but not foaming. Therefore, there is an interference device design with eccentric setting of the stirring shaft, but the simple design of the eccentric shaft is not...

Problems solved by technology

Although it solves the sealing problem of the rotating element, since the stirrer rotates at a high speed, the speed is 2500~4000r.p.m, and the S / N polarity is continuously and rapidly switched during the rotation, which is likely to cause magnetic disorder and affect the stirring. and frothing control, limiting the effect of stirring or frothing
