The second limiting flange 812 is spaced from the outer wall of the second mounting base 38. The second sealing gasket 83 is sleeved on the sleeve body and clamped between the second mounting base 38 and the second limiting flange 812. The specific way in which the second locking member 85 locks the second sealing sleeve 81 is not limited in the specification. For example, the second locking member 85 can be a fastener such as a screw or a pin, or the second locking member 85 can be threadedly locked with the second sealing sleeve 81. In the embodiment, the peripheral wall of the second sealing sleeve 81 located outside the second mounting cavity 32 is provided with external threads, the second locking member 85 is a locking nut, and the second locking member 85 is threadedly connected with the second sealing sleeve 81. When the second locking member 85 is tightened, the second sealing sleeve 81 presses the second sealing gasket 83 against the outer wall of the second mounting base 38 through the second limiting flange 812, thereby improving the sealing between the second mounting base 38 and the second sealing sleeve 81.

[0047] The structure of the second sealing assembly 80 is substantially the same as that of the first sealing assembly 60. In the embodiment, the second sealing assembly 80 can also include a bearing and an oil seal. The bearing is arranged between the second sealing sleeve 81 and the rotating shaft 54, and the oil seal is arranged between the second sealing sleeve 81 and the rotating shaft 54 and located at one end of the bearing.

[0048] The output shaft 72 and the rotating shaft 54 are drivingly connected through a connecting assembly 90. The specific structure of the connecting assembly 90 is not limited in the specification. For example, in some embodiments, the connecting assembly 90 can include a fastener such as a flange for connection. In the embodiment, the connecting assembly 90 includes the first coupling member 92 and the second coupling member 94 described above. The first coupling member 92 is accommodated in the first mounting cavity 121 and rotationally connected to the output shaft 72. It should be understood that the "rotationally connected" between the first coupling member 92 and the output shaft 72 should be understood as that the first coupling member 92 is relatively fixed with the output shaft 72, and the first coupling member 92 can rotate with the output shaft 72. The specific way of rotationally connecting between the first coupling member 92 and the output shaft 72 is not limited in the specification. For example, the first coupling member 92 can be fixedly connected with the output shaft 72 through a fastener such as a screw or a bolt to achieve rotationally connection. In the embodiment, the first coupling member 92 is sleeved on one end of the output shaft 72 located in the first mounting cavity 121, and the first coupling member 92 is rotationally connected with the output shaft 72 through a fastener screw.

[0049] In order to avoid frictional resistance caused by contact between the first coupling 92 and the first sealing sleeve 61, in the embodiment, a limiting step can be arranged on the peripheral wall of the output shaft 72 to space the first coupling 92 from the first sealing sleeve 61. The size of the first coupling 92 in the axial direction of the output shaft 72 is less than or equal to the depth dimension of the first mounting cavity 121, so that the first coupling 92 does not protrude relative to the opening of the first mounting cavity 121.

[0050] The second coupling 94 is accommodated in the second mounting cavity 32 and is rotationally connected to the rotating shaft 54. It should be understood that the "rotationally connected" between the second coupling 94 and the rotating shaft 54 is understood as that the second coupling 94 is relatively fixed with the rotating shaft 54, and the rotating shaft 54 can rotate with the rotation of the second coupling 94. The present specification does not limit the way of rotationally connecting between the second coupling 94 and the rotating shaft 54, for example, the second coupling 94 can be fixed with the rotating shaft 54 by fasteners such as screws, bolts, etc. to achieve rotationally connected. In the embodiment, the second coupling 94 is sleeved on one end of the rotating shaft 54 located in the second mounting cavity 32, and the second coupling 94 is rotationally connected with the rotating shaft 54 through the fastener screw.

[0051] In the embodiment, the second coupling 94 is provided with a clearance groove 941, and at least part of the structure of the second sealing sleeve 81 and the second locking member 85 are accommodated in the clearance groove 941. The clearance groove 941 is arranged on the side of the second coupling 94 facing the second sealing sleeve 81, and one end of the second sealing sleeve 81 and the second locking member 85 are accommodated in the clearance groove 941, which improves the compactness of the structure and reduces the axial dimension of the second sealing assembly 80 and the second coupling 94 as a whole, thereby reducing the height dimension of the stirring barrel module of the food processing equipment 100. In order to avoid frictional resistance caused by contact between the second coupling 94 and the second sealing sleeve 81, in the embodiment, a limiting step can be arranged on the peripheral wall of the rotating shaft 54 to space the bottom of the clearance groove 941 from the second sealing sleeve 81.

[0052] The size of the second coupling 94 in the axial direction of the rotating shaft 54 is less than or equal to the depth dimension of the second mounting cavity 32, so that the second coupling 94 does not protrude relative to the opening of the second mounting cavity 32. The second coupling 94 is completely accommodated in the second mounting cavity 32, so that the inner container 30 can be placed flat on the table after being disassembled from the receiving barrel 12, without the need for a foot support.

[0053] The first coupling member 92 and the second coupling member 94 are coaxially arranged, and in the embodiment, the first coupling member 92 and the second coupling member 94 are detachably connected, and the first coupling member 92 and the second coupling member 94 are rotationally connected by engagement. Specifically, the side of the first coupling member 92 facing the second coupling member 94 can be provided with engagement teeth, and the side of the second coupling member 94 facing the first coupling member 92 is also provided with engagement teeth. When the inner container 30 is placed in the storage barrel 12, the first coupling member 92 and the second coupling member 94 are engaged to achieve rotational connection, for receiving the torque from the driving member 70. In some embodiments, the engagement teeth of the first coupling member 92 can be provided with a slope to play a certain guiding role when the engagement teeth of the second coupling member 94 are docked, facilitating docking and installation.

[0054] In order to make the first coupling member 92 and the second coupling member 94 have sufficient engagement depth between the engagement teeth when engaged with each other, in the embodiment, the engagement teeth of the second coupling member 94 have a larger thickness. Specifically, the second coupling member 94 can include a connecting portion 943 and an engagement tooth portion 945, the connecting portion 943 is sleeved outside the rotating shaft 54, and the engagement tooth portion 945 is connected to the outer periphery of the connecting portion 943 and protrudes relative to the connecting portion 943 towards the side of the second sealing sleeve 81, so as to form the above-mentioned accommodation groove 941 together with the connecting portion 943. The engagement tooth portion 945 has a larger depth relative to the connecting portion 943, so as to ensure that when engaged with the first coupling member 92, it has sufficient engagement depth, and improves the transmission stability.

[0055] When the food processing device 100 provided in the present application is used, the output shaft 72 of the driving member 70 drives the rotating shaft 54 to rotate through the connecting assembly 90, and the rotating shaft 54 drives the blade 52 to process the food materials in the inner container 30. Among them, the second coupling member 94 connected to the rotating shaft 54 is accommodated in the second installation cavity 32, and the second installation cavity 32 is recessed in the inner container 30, which improves the structural compactness, and the height dimension of the stirring barrel module of the food processing device 100 is relatively small. The size of the second coupling member 94 in the axial direction of the rotating shaft 54 is less than or equal to the depth dimension of the second installation cavity 32, so that the second coupling member 94 does not protrude relative to the opening of the second installation cavity 32. The second coupling member 94 is completely accommodated in the second installation cavity 32, so that the inner container 30 can be placed flat on the table after being disassembled from the storage barrel 12, without the need for a foot support.
