[0038] In Figure 2 In the embodiment shown, the cup assembly 20 further comprises a stirring blade 23 rotatably arranged in the heating disc 211, a blade shaft of the stirring blade 23 penetrates the heating disc 211 for engaging with a motor shaft in the base 10, blade leaves of the stirring blade 23 are located in the cup cavity for stirring and crushing food materials.

[0039] Please refer to Figure 3 and Figure 4 , Figure 3 To Figure 2 The exploded view of the heating disc 211 and the stirring blade 23 is shown in Figure 4 is a cross-sectional view of the heating disc 211 and the stirring blade 23 in an assembled state.

[0040] The heating disc 211 comprises a disc body 25 and a heating portion 26, the disc body 25 is sealingly engaged with a bottom end of the cup body 210 as a cup bottom of the cup body 210, and the disc body 25 and the cup body 210 together enclose a cup cavity. The heating portion 26 can generate heat, and the heating portion 26 is in contact with the disc body 25 to transfer heat to the disc body 25. The heating disc 211 further comprises a sealing ring 27, a temperature controller 28 and a temperature sensor 29, the sealing ring 27 is used to seal the gap between the disc body 25 and the cup body 210 at the opening. The temperature controller 28 can control the on-off of the heating portion 26 according to the temperature threshold, and the temperature sensor 29 is used to detect the temperature in the cup cavity.

[0042] The heating portion 26 comprises a heating tube 260 and a heat conducting member 261, the heat conducting member 261 comprises a disc bottom 2610 in a central region and a side wall 2611 connected to a periphery edge of the disc bottom 2610, the disc bottom 2610 is in thermal conduction with the bottom wall 251, for example, the disc bottom 2610 is welded with the bottom wall 251 to realize thermal conduction.

[0043] The side wall 2611 comprises a conduction portion 2611a surrounded by the heating tube 260 and in thermal conduction with the heating tube 260, and a connecting portion 2611b connecting the conduction portion 2611a and the disc bottom 2610, at least one of the connecting portion 2611b and the disc bottom 2610 has a wall thickness smaller than that of the conduction portion 2611a.

[0044] According to the above description, the wall thickness of the side wall 2611 at the conducting part 2611a is larger, the wall thickness at the connecting part 2611b or the bottom 2610 is smaller, and is smaller than the wall thickness of the conducting part 2611a, which makes the heat loss smaller in the heat transfer process, and is beneficial to improve the heating efficiency.

[0045] For example, the wall thickness at the connecting part 2611b can be separately set to be smaller than the wall thickness of the conducting part 2611a, or the wall thickness at the bottom 2610 can be separately set to be smaller than the wall thickness of the conducting part 2611a. In the embodiment, the wall thicknesses at the connecting part 2611b and the bottom 2610 are both smaller than the wall thickness of the conducting part 2611a.

[0046] In Figure 4 In the embodiment shown, the conducting part 2611a is provided with a uniform wall thickness, the connecting part 2611b and the bottom 2610 are provided with a uniform wall thickness, and the wall thicknesses of the connecting part 2611b and the bottom 2610 are equal. In this way, the wall thicknesses of the conducting part 2611a, the connecting part 2611b and the bottom 2610 in the circumferential direction are uniform, which makes the heat transferred from the conducting part 2611a to the bottom 2610 through the connecting part 2611b also relatively uniform, and the wall thicknesses of the connecting part 2611b and the bottom 2610 are equal, which makes the heating at the connecting part 2611b and the bottom 2610 more uniform, and can also effectively prevent the bottom from being burnt.

[0047] In one embodiment, as Figure 4 shown, the total height of the heat conducting member 261 is H2, the distance between the bottom end of the heat generating pipe 260 and the bottom end of the heat conducting member 261 is H1, and 0.2≤H1:H2≤0.6. For example, the ratio of H1 to H2 can be 0.2, 0.3, 0.4, 0.5, 0.6. In this way, sufficient installation space can be provided for the heat generating pipe 260, and the welding or heat conduction of the heat generating pipe 260 and the heat conducting member 261 is facilitated.

[0048] Please refer to Figure 5 , Figure 5 for Figure 4 the enlarged view of the A part in FIG. 1.

[0049] In one embodiment, at the joint between the conducting part 2611a and the connecting part 2611b, the outer surfaces of the conducting part 2611a and the connecting part 2611b are connected by a circular arc surface 2611c, and the radius of the circular arc surface 2611c is R2. The circular arc surface 2611c can realize the smooth transition of the conducting part 2611a and the connecting part 2611b in the outer surface, and reduce the heat loss due to the sudden change of the cross section.

[0050] In one embodiment, the conducting portion 2611a has a uniform wall thickness of M1, and the disc bottom 2610 has a uniform wall thickness of M2, where 1 / 3≤M2:M1<1. In this way, the ratio of the wall thicknesses of the disc bottom 2610 and the conducting portion 2611a is relatively appropriate, avoiding excessive thermal resistance due to a large difference in wall thickness. The ratio of M2 to M1 can be 1 / 3, 1 / 2, 2 / 3, 3 / 4, 4 / 5, but is not limited thereto.

[0051] In one specific embodiment, M1 is 3 mm and M2 is 1 mm. In another embodiment, M1 is 2 mm and M2 is 1.5 mm.

[0052] In Figure 5 In the illustrated embodiment, the top of the conducting portion 2611a is provided with an outwardly bent flange 2611c, and the top end of the heat pipe 260 is also in thermal conduction with the flange 2611c, thereby increasing the heat conduction area between the heat pipe 260 and the conducting portion 2611a. The heat pipe 260 can be welded to the conducting portion 2611a.

[0053] In one embodiment, as Figure 5 illustrated, the inner surface and the outer surface of the conducting portion 2611a are provided as circular arc surfaces with the same center, and the inner surface and the outer surface of the connecting portion 2611b are provided as circular arc surfaces with the same center. The radius of the outer surface of the conducting portion 2611a is R1, and the radius of the outer surface of the connecting portion 2611b is R3, where R1>R3. In this way, the conducting portion 2611a is less curved than the connecting portion 2611b, making it more convenient to weld the heat pipe 260 to the conducting portion 2611a. The conducting portion 2611a can also be connected to the disc bottom 2610 in a circular arc transition through the connecting portion 2611b, so that the heat conduction member 261 is formed as a disc-shaped structure with a large mouth and a small bottom.

[0054] In this embodiment, the shapes of the heat conduction member 261 and the disc body 25 are adapted to each other to improve the fit during assembly. For example, the bottom wall 251 of the disc body 25 can be welded and in thermal conduction with the disc bottom 2610 of the heat conduction member 261, and the side wall 252 of the disc body 25 can be welded and in thermal conduction with the side wall 2611 of the heat conduction member 261.

[0055] Please refer to Figure 6 , Figure 6 is another sectional view of the heating disc 211 and the stirring knife 23 in the assembled state.

[0056] In one embodiment, the bottom wall 251 is provided as a circular bottom wall, and the intersection line A between the plane in which the central axis O of the bottom wall 251 is located and the inner surface of the side wall 252 is an arc-shaped curve convexly away from the central axis O or a slant line gradually away from the central axis O from the bottom wall 251. The line L connecting the lowest point and the highest point of the intersection line A forms an obtuse angle a with the bottom wall 251, and 90°≤a≤160°. The angle is appropriately sized, and correspondingly, the inclination of the side wall 252 towards the outside is appropriate. Further, 105°≤a≤135°. In a specific embodiment, a can be 90°, 100°, 105°, 110°, 120°, 130°, 135°, 140°, 150°, 160°, but is not limited thereto.

[0057] In one embodiment, the heating disc 211 is provided with a stirring blade 23, which includes a blade shaft 230 and a first blade leaf 231 provided on the blade shaft 230. The blade shaft 230 is rotatably installed at the center of the bottom wall 251 and the disc bottom 2610 and penetrates out from the side of the disc bottom 2610 away from the bottom wall 251, and the first blade leaf 231 is located above the bottom wall 251. The axis of the blade shaft 230 coincides with the central axis O.

[0058] In one embodiment, the end of the first blade leaf 231 is opposite to the middle part of the heating tube 260 along the axial direction of the blade shaft. That is, the position where the heating tube 260 is located is opposite to the disturbance area of the first blade leaf 231, and the first blade leaf 231 can increase the disturbance of the food material in this area when stirring, so as to avoid the adhesion of the food material due to the concentration of heat and also facilitate the diffusion and more uniform heat absorption of the food material.

[0059] In one embodiment, the distance between the end of the first blade leaf 231 and the bottom wall 251 along the axial direction of the blade shaft is L1, and the distance between the lowermost end of the heating tube 260 and the bottom wall 251 along the axial direction of the blade shaft is L2, wherein 1 / 4≤L1:L2≤3 / 4. The proportion size can appropriately size the gap between the first blade leaf 231 and the bottom wall 251, prevent the bottom from being stuck by the stirring of the first blade leaf 231, avoid the contact with the bottom wall 251, and ensure the high heat transfer efficiency. Further, 0.3≤L1:L2≤0.6. L1:L2 can be 0.25, 0.3, 0.4, 0.5, 0.6, 0.75.

[0060] Specifically, in one embodiment, 8mm≤L1≤15mm, 6mm≤L2≤20mm. For example, L1 can be set to 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, but not limited to. L2 can be set to 6mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, but not limited to. In this way, L1 and L2 are relatively small, which can make the gap between the first blade 231 and the bottom wall 251 appropriate, the height of the side wall 252 appropriate, and ensure high heat transfer efficiency.

[0061] In one embodiment, 5mm≤L1≤25mm, 6mm≤L2≤60mm. For example, L1 can be set to 5mm, 8mm, 12mm, 14mm, 16mm, 18mm, 20mm, 25mm, but not limited to. L2 can be set to 6mm, 10mm, 20mm, 30mm, 40mm, 50mm, 60mm, but not limited to. In this way, L1 and L2 are relatively large, which can make the gap between the first blade 231 and the bottom wall 251 larger, the height of the side wall 252 larger, and the heat generation area larger.

[0062] In one embodiment, the distance between the end of the first blade 231 and the side wall 252 of the disc body 25 along the radial direction of the blade shaft is P1, and the single-side size of the side wall 252 in the projection of the blade shaft along the axial direction is P2, 1 / 10≤P1:P2≤3 / 5. This size ratio can make the gap between the first blade 231 and the side wall 252 of the disc body 25 appropriate, avoiding contact with the side wall 252. Further, 0.15≤P1:P2≤0.4. P1:P2 can be 0.1, 0.15, 0.2, 0.3, 0.4, 0.5, 0.6.

[0063] In one embodiment, 3mm≤P1≤25mm, 5mm≤P2≤30mm. In this way, the gap between the first blade 231 and the side wall 252 is small, which can increase the turbulence range and reduce the occurrence of food material sticking to the side wall 252. For example, P1 can be set to 3mm, 5mm, 10mm, 15mm, 20mm, 25mm, but not limited to. P2 can be set to 5mm, 10mm, 20mm, 30mm, but not limited to.

[0064] In one embodiment, 3mm≤P1≤25mm, 5mm≤P2≤60mm. In this way, the gap between the first blade 231 and the side wall 252 is small, the single-side size of the side wall 252 is appropriately increased, and the heating area is increased. For example, P1 can be set to 3mm, 5mm, 10mm, 15mm, 20mm, 25mm, but is not limited thereto. P2 can be set to 5mm, 10mm, 20mm, 30mm, 40mm, 50mm, 60mm, but is not limited thereto.

[0065] In one embodiment, the stirring blade 23 can include a plurality of blades, such as a second blade, a third blade, and the like, which can be arranged axially along the blade shaft or symmetrically about the blade shaft axis, and can be selected and arranged according to the actual application scenario.
