The lower part of the knife shaft 5 extends out of the inner pot 2 and is connected to the upper connector 6 which is transmission coupled with the lower connector 4. The upper part of the knife shaft 5 extends into the inner cavity of the inner pot 2 and is connected to the dough knife 7. The bottom of the outer pot 1 is fixedly connected to the supporting cylinder 8. The inner pot 2 is placed on top of the supporting cylinder 8. The output shaft 31 and the lower connector 4 are placed at the center of the supporting cylinder 8, and a rotating connecting piece is provided on the supporting cylinder 8. The bottom surface of the inner pot 2 is connected to a connecting cylinder 9 nested in the supporting cylinder 8. The knife shaft 5 and the upper connector 6 are placed at the center of the connecting cylinder 9, and a screw-on fitting is provided on the connecting cylinder 9 corresponding to the rotating connecting piece. The outer pot 1 cooperates with the screw-on fitting through the rotating connecting piece to limit the axial rotation of the inner pot 2 relative to the outer pot 1.

[0027] This dough mixer can lock the inner pot 2 when the dough knife 7 rotates through the cooperation of the supporting cylinder 8 and the connecting cylinder 9, limiting the axial rotation of the inner pot 2 following the knife shaft 5, and the supporting cylinder 8 props up the inner pot 2 to a certain height. On the one hand, there is enough space between the upper connecting head 6 and the lower connecting head 4 for coupling, and the production and assembly difficulties are low. On the other hand, there is more space between the inner pot 2 and the bottom of the outer pot 1 to store more drinking water, and high-temperature steam can be generated for a long time during heating, so that the dough mixer can steam food for a longer time.

[0028] Specifically, the rotating connecting member includes a plurality of rotating snap-fitting blocks 81, which are evenly distributed on the top of the inner wall of the supporting cylinder 8; the rotating fitting member includes a plurality of rotating snap-fitting grooves 91 in the shape of an inverted L, which are evenly distributed on the outer wall surface of the connecting cylinder 9. The rotating snap-fitting blocks 81 cooperate with the rotating snap-fitting grooves 91 to make the supporting cylinder 8 and the connecting cylinder 9 snap-fitted and connected.

[0029] The rotating buckle groove 91 includes an axially extending buckle section 911 and a longitudinally extending entrance section 912, and the width of the entrance section 912 gradually decreases from the entrance end toward the buckle section 911; the entrance section 912 of this structure makes it easier to introduce the rotating buckle block 81 into the rotating buckle groove 91, thereby improving assembly efficiency.

[0030] A connecting bottom plate 92 is also provided on the upper part of the connecting cylinder 9, and a sealing sleeve 10 is provided on the edge of the connecting bottom plate 92. The connecting cylinder 9 is fastened to the bottom surface of the inner tank 2 through the connecting bottom plate 92. At least the lower part of the connecting cylinder 9 is in the shape of a truncated cone with a wide upper part and a narrow lower part. The connecting cylinder 9 with this structure makes it easier to insert the connecting cylinder 9 into the supporting cylinder 8, thereby improving the assembly efficiency.

[0031] The sealing sleeve 10 is provided with an upper sealing surface 1001 and a lower sealing surface 1002, the upper sealing surface 1001 is crimped between the connecting bottom plate 92 and the bottom surface of the inner liner 2, the lower sealing surface 1002 is crimped between the connecting bottom plate 92 and the supporting cylinder 8, and an avoidance groove 921 is provided on the bottom surface of the connecting bottom plate 92 corresponding to the top edge of the supporting cylinder 8; after the connecting cylinder 9 is assembled to the bottom surface of the inner liner 2 through the fastening unit, the upper sealing surface 1001 seals the gap between the inner liner and the connecting bottom plate 92 to prevent water leakage in the gap between the knife shaft and the inner liner 2;

[0032] When the inner pot 2 is embedded in the outer pot 1, the supporting cylinder 8 and the connecting cylinder 9 are screwed together, and the top edge of the supporting cylinder 8 and the rotating buckle block 81 compress the lower sealing surface 1002 of the sealing sleeve 10. On the one hand, the rotating buckle block 81 can completely enter the buckle section 911 to perform subsequent circumferential rotation. On the other hand, the lower sealing surface 1002 maintains elastic potential energy, pushing the rotating buckle block 81 to press tightly against the bottom surface of the buckle section 911 to prevent the connecting cylinder 9 from loosening after the screw connection. The avoidance groove 921 makes the lower sealing surface 1002 not only compressed by the plane, but also deformed under the action of the top edge of the supporting cylinder 8, thereby increasing the elastic potential energy.

[0033] An axial introduction slope 811 cooperating with the entrance section 912 is provided on the upper outer side of the rotating buckle block 81, and a screw-in introduction slope 812 cooperating with the buckle section 911 is provided on the lower side wall of the rotating buckle block 81; the axial introduction slope 811 guides the connecting cylinder 9 to be quickly inserted into the supporting cylinder 8, and the screw-in introduction slope 812 converts the circumferential force into an axial force when the connecting cylinder 9 rotates axially relative to the supporting cylinder 8, so that the rotating buckle block 81 can be squeezed into the buckle section 911 from the entrance section 912.

[0034] It also includes a base 11, and the outer pot 1 is detachably or non-detachably connected to the base 11. A driving device 12 and a control system 13 electrically connected to the driving device 12 are arranged in the base 11. The lower part of the output shaft 31 is connected to the output end of the driving device 12; the driving device 12 mainly includes a motor, and the output end of the motor is connected to the output shaft 31 through a transmission assembly composed of one or more of gears, turbines, and worm shafts, so that the dough kneading knife 7 can rotate at a uniform speed to knead the dough.

[0035] The base 11 includes a shell 101 and a bottom cover 21 fixedly assembled on the shell 101, the supporting cylinder 8 is connected to the bottom cover 21, and the mouth of the bottom cover 21 is detachably covered with a cover 22, the cover 22 and the bottom cover 21 together constitute an outer pot 1, and define a steam chamber 102 inside, the inner pot 2 is placed in the steam chamber 102, the cover 22 is mainly covered on the outer periphery of the inner pot 2, and the inner pot 2 is provided with a steam inlet structure connecting the steam chamber 102 and the inner cavity of the inner pot 2.

[0037] In more embodiments, the steam inlet structure also includes a plurality of air inlets opened on the side wall of the inner tank 5, and the inner cavity of the inner tank 5 is connected to the steam chamber 102 through the plurality of air inlets; however, opening the air inlets on the side wall of the inner tank 5 may affect the maximum capacity of the inner tank, so this structure is not used as a preferred embodiment and will not be elaborated or marked in detail here and in the accompanying drawings.

[0038] The bottom cover 21 is a bowl-shaped structure and is made of metal material in one piece, and a water storage tank is defined inside. The inner pot 2 is supported by a supporting cylinder 8 to separate a water boiling space from the water storage tank, and a heating plate 24 electrically connected to the control system 13 is assembled at the bottom of the bottom cover 21.

[0039] When in use, a certain amount of clean water is poured into the water tank, and the heating plate 24 heats the clean water in the water tank, so that the steam chamber 102 generates high-temperature steam, and the steam fills the steam chamber 102. Then the steam rises into the inner pot to heat and steam the dough, so that the dough mixer also has the function of steaming dough.

[0040] The bottom of the bottom cover 21 is equipped with a water level sensor 16, which is electrically connected to the control system 13. The sensing surface of the water level sensor 16 is placed in or outside the water tank.
