A reducer (125) is fixedly connected inside the casing (3), and the input end of the reducer (125) is fixedly connected to the other end of the transmission shaft (123), and the output end of the reducer (125) is fixedly connected to an eccentric wheel (126), and a hose (127) is installed on the water injection pipe (122), and the hose (127) is located below the eccentric wheel (126).

8. A dough kneading process of a dough mixer for producing bread, biscuits and other pasta according to any one of claims 1 to 7, characterized in that it comprises the following steps:

S1. Put the prepared flour material into the mixing drum (5), then place the mixing drum 5 on the top of the base (1), and position the bottom of the mixing drum (5) by means of the positioning sleeve (6). During the placement process, insert the positioning block (7) into the positioning hole (8) at the bottom of the mixing drum (5) for positioning;

S2, placing the prepared water source into the water injection assembly (12), or directly placing it into the mixing drum (5), so that the water source and the flour material are in initial contact;

S3, by driving the casing (3) downward, so that the cover plate (9) at the bottom of the casing (3) is buckled on the top of the mixing drum (5), and the mixing assembly (10) is inserted into the mixing drum (5), and finally the motor (111) in the driving assembly (11) is driven, and the stirring end of the mixing assembly (10) is driven to rotate by the started motor (111), thereby forming a dough kneading operation;

S4. If the amount of dough material is greater than or equal to half of the internal capacity of the mixing drum (5), the motor (111) in the driving assembly (11) is driven so that the started motor (111) not only drives the stirring end of the stirring assembly (10) to rotate, but also drives the stirring end of the stirring assembly (10) to reciprocate up and down, thereby forming a dough kneading operation.
