The food processor comprises a host and a motor 12, wherein an air duct housing is arranged on the outer side of the motor 12 to form a motor assembly, the motor assembly is arranged in the host, the air duct housing comprises two half-shells 31 and a bottom cover 32 arranged on the lower side of the half-shells, the two half-shells 31 are buckled outside the motor 12 and form a heat dissipation air duct inside, the bottom cover 32 is connected to the bottom end of the half-shells 31, and the bottom cover 32 is hollow and forms an exhaust channel.

The host comprises a motor mounting seat 11 and a bottom cover 4 which are assembled up and down, the motor assembly is connected with the motor mounting seat 11, and the bottom cover 4 seals the motor mounting seat 11. The bottom cover 4 is provided with an air inlet 41 and an air outlet 42, preferably, the number of the air inlets 41 is two, the two air inlets are respectively located at two sides of the bottom cover 4, and the air outlet 42 is located at the rear side of the bottom cover 4.

The two half shells 31 are provided with buckles 311 which are buckled with each other, and are buckled with each other and installed on the outer side of the motor 12, the bottom cover 32 is assembled on the bottoms of the motor and the half shells, and preferably, a fan at the bottom of the motor 12 stretches into the bottom cover 32. The heat dissipation air duct is formed between the half-divided shell 31 and the motor 12, the exhaust channel is formed inside the bottom cover 32, preferably, the exhaust channel comprises a vertical section and a transverse section, the vertical section is communicated with the heat dissipation air duct, the transverse section is communicated with the air outlet, and the fan is located at the cross joint of the transverse section and the vertical section. In the working process, the fan drives air to flow, so that air in the host is discharged from the air outlet, at the moment, negative pressure is formed in the host, and then, external air flows into the host from the air inlet, flows into the heat dissipation air duct from the air duct inlet at the upper end of the air duct housing, flows through the motor and flows into the exhaust channel, and is discharged through the fan, so that the whole heat dissipation cycle is formed. In the whole process, as the motor component is formed between the air duct housing and the motor, the structure and the size of the motor component are stable, and the heat dissipation and the noise reduction effect are ensured to be reliable.

While the invention has been described in terms of embodiments, it will be appreciated by those skilled in the art that the invention is not limited thereto but rather includes the drawings and the description of the embodiments above. Any modifications which do not depart from the functional and structural principles of the present invention are intended to be included within the scope of the appended claims.
