Description

Technical Field

[0001] This application relates to the field of electric mixer technology, and more specifically to a motor assembly structure for an electric mixer. Background Technology

[0002] Electric mixers are used in households for functions such as beating eggs and mixing ingredients. Patent application number CN202021325598.9 discloses an electric egg beater, including a plastic shell. A USB charging port is located on one side of the upper part of the plastic shell. A lithium battery is located in the middle of the plastic shell, and a circuit board is connected to the upper end of the lithium battery. A switch connected to the circuit board is located in the middle of the upper part of the plastic shell. A motor is located at one end of the middle of the plastic shell, and a drive shaft is located at the front center of the motor. A mixing head connector with a through hole is located at one end of the plastic shell. A spring connector is located at one end of the drive shaft, inserted into a groove in the mixing head connector. The spring connector is fixedly connected to the mixing head connector. A power transmission spring is sleeved inside the slot of the spring connector on the drive shaft. A steel wire mixing head is located at the end of the mixing head connector away from the spring connector. This egg beater requires the internal motor to be connected to the circuit board via wire soldering, which is relatively complex to assemble and prone to poor contact after prolonged use, leading to malfunction.
