Furthermore, the lower end of the head 4 has an exhaust channel 44, one end of the exhaust channel 44 is an air inlet 441 located on the lower end surface of the head 4, and the other end of the exhaust channel 44 is a pressure relief hole 442 located on the outer side surface of the head 4. When the lower tail end of the machine head 4 is arranged at the top end of the base 1, the lower tail end of the machine head 4 is connected with the upper tail end of the cavity 13 in a sealing way through a second sealing ring 46, a steam supply channel 5 formed by a gap is arranged between the lower end surface of the machine head 4 and the cup cover 3, and the steam supply channel 5 is communicated with the shaft hole 31; the power shaft 431 of the power part 43 is in transmission connection with the upper end of the transmission shaft 24 positioned in the shaft hole 32, and the steam inlet 441 is communicated with the steam exhaust hole 35 so as to communicate the inside of the cooking cup 2 with the outside atmosphere through the steam exhaust hole 35 and the steam exhaust channel 44.

When a steam heating food processor is required to be used for steaming and stirring food, after the machine head 4 and the cup cover 3 are taken down, a proper amount of water is added into the water storage cavity 14, one or more food materials are placed in the food processing cup 2, then the cup cover 3 and the machine head 4 are sequentially installed, after the machine head 4 is started, the power shaft 431 of the power part 43 drives the cutter shaft 231 to rotate at high speed through the transmission shaft 24 by taking the cup shaft 21 and the shaft sleeve 32 as limits, and drives the stirring cutter 232 to stir and chop the food materials in the food processing cup 2; meanwhile, the heater 12 heats the water in the water storage cavity 14 to generate steam, the steam enters the steam guide channel 25 through the steam supply channel 5 and enters the food processing cup 2 from the lower through hole 252, so that the food is heated and steamed by the steam, and the steaming and stirring are integrated, thereby being convenient to use. After the steam enters the cooking cup 2, the steam contacts with the food which is stirred and crushed in the cooking cup 2 and rolls, so that the food is heated, the steam enters the steam exhaust channel 44 from the steam exhaust hole 35 and is exhausted through the pressure relief hole 442 at the tail end of the steam exhaust channel 44, and a flow path for heating the steam is formed.

Therefore, the steam guide channel 25 for providing steam to enter the cooking cup 2 is integrated inside the cutter shaft 231, and the lower through hole 252 for steam to enter the cooking cup 2 is positioned at the lower end of the cutter shaft 231, so that the steam directly enters the cooking cup 2 from the middle lower part or even the bottom of the cooking cup 2, the structure can directly guide the steam to directly contact with food in the cooking cup 2 through the steam hole 33, the probability that the steam flows to the depth direction inside the cooking cup 2 is objectively increased, and the defect that the heating efficiency is poor because a large amount of steam cannot actually flow into the cooking cup 2 in the prior art is overcome; meanwhile, in the process that the power part 43 drives the cutter shaft 231 to drive the stirring cutter 232 to rotate at a high speed, the cutter shaft 231 rotates at a high speed and the stirring cutter 232 continuously stirs and cuts food to drive air in the cooking cup 2 to generate transverse rotating airflow, turbulent flow is generated between the transverse rotating airflow and steam, the chance of heat exchange between the steam and the food is greatly improved through the turbulent flow, the utilization rate of the steam is improved, and the efficiency of heating and cooking is higher.

Wherein, the pressure relief hole 442 comprises a through hole and even a micro-pressure hole formed by soft glue sealing in the through hole. The pore diameter of the micro-pressure hole is very small, and the difficulty of directly processing a through hole with a very small pore diameter is higher, so that a through hole with a small pore diameter is formed by arranging a soft glue seal in a through hole with a large pore diameter to form the micro-pressure hole. It can be understood that when the pressure relief holes 442 are micro-pressure holes, the steam is not easily discharged from the pressure relief holes 442 so that part of the steam can be accumulated in the cooking cup 2 to have a pressure greater than atmospheric pressure and increase the heat exchange chance between the steam and the food, thereby cooking the food in the cooking cup 2 more rapidly.

In one embodiment, the head 4 comprises a head body 41 with a power part 43 inside and a bottom cover 45 detachably mounted on the lower end surface of the head body 41, the steam exhaust channel 44 is formed by the gap between the lower end surface of the head body 41 and the bottom cover 45, the steam inlet 441 is located on the bottom cover 45, and the steam supply channel 5 is formed by the gap between the bottom cover 45 and the cup cover 3.
