[0033] An embodiment of the utility model provides a kind of stirring assembly, it is applied to ice cream machine, refer to Figures 1-5 , comprising:
[0034] Stirring shaft 1, including connecting rod 11 and connecting head 12, the connecting rod 11 one end is connected with the ice cream machine, the other end is connected with the connecting head 12, the first magnetic attraction piece 13 is equipped on the connecting head 12, the outer side wall of the connecting head 12 is equipped with second spiral thread structure 123;
[0035] Stirring knife 2, it is sleeved on the connecting head 12, the stirring knife 2 includes installation part 21, the installation part 21 is equipped with connecting hole 211, the connecting hole 211 includes first accommodating cavity 2111 and second accommodating cavity 2112, the first accommodating cavity 2111 is communicated with the second accommodating cavity 2112, the inner side wall of the first accommodating cavity 2111 is equipped with first spiral thread structure 212, the first spiral thread structure 212 is connected with the second spiral thread structure 123, the second accommodating cavity 2112 is equipped with second magnetic attraction piece 24, the first magnetic attraction piece 13 and the second magnetic attraction piece 24 are mutually adsorbed.
[0036] The embodiment solves the problem of easy loosening and falling of the stirring knife 2 in the ice cream machine stirring assembly. The first magnetic member 13 is arranged on the stirring shaft 1, and the second magnetic member 24 is arranged on the stirring knife 2, so that the first magnetic member 13 and the second magnetic member 24 are attracted to each other. The magnetic attraction connection can prevent the stirring knife 2 from falling off the stirring shaft 1 during stirring, avoiding contamination of the food materials. Since the outer side wall of the connecting head 12 is provided with the second spiral thread structure 123, and the inner side wall of the first accommodating cavity 2111 is provided with the first spiral thread structure 212, when the stirring shaft 1 moves downward and connects with the stirring knife 2, the first spiral thread structure 212 and the second spiral thread structure 123 are screwed with each other, further preventing loosening and falling of the stirring knife 2, and making the connection between the stirring shaft 1 and the stirring knife 2 more firm. Specifically, in use, the stirring shaft 1 moves downward, the first spiral thread structure 212 gradually contacts and starts to screw with the second spiral thread structure 123, so that the first magnetic member 13 contacts and is attracted to the second magnetic member 24, thereby fixing the stirring knife 2 on the stirring shaft 1 and starting to perform the stirring action, completing the feeding state of the stirring assembly. When the stirring is completed, the stirring assembly moves upward, the first spiral thread structure 212 and the second spiral thread structure 123 gradually separate, and at the same time, the attraction between the first magnetic member and the second magnetic member gradually weakens. When the first spiral thread structure 212 and the second spiral thread structure 123 are completely separated, that is, when the stirring shaft 1 and the stirring knife 2 are completely separated, the retraction and reset state is completed. It should be noted that in the embodiment, the first magnetic member 13 and the second magnetic member 24 are magnets or magnetite or other food materials with magnetic attraction.
[0037] Further, the connecting head 12 is provided with a mounting hole 121, and the first magnetic member 13 is arranged in the mounting hole 121. In the embodiment, one end of the connecting head 12 is sleeved on the connecting rod 11, and the other end is provided with a mounting hole 121 with an opening downward. The first magnetic member 13 is fixedly installed in the mounting hole 121. By designing the opening of the mounting hole 121 downward, it can prevent water, dust and other impurities from entering the mounting hole 121, thereby affecting the performance of the first magnetic member 13, ensuring the stable connection between the stirring knife 2 and the stirring shaft 1, and avoiding displacement of the magnetic member due to mechanical vibration during stirring.
[0038] Further, the mounting hole 121 has the same hole diameter as the second accommodating cavity 2112, and the hole diameters of the mounting hole 121 and the second accommodating cavity 2112 correspond to each other. When the connecting head 12 is connected to the stirring blade 2, the connecting head can be accurately inserted into the second accommodating cavity without additional adjustment or calibration because the hole diameter of the mounting hole 121 is the same as the hole diameter of the second accommodating cavity 2112. When the first magnetic member 13 and the second magnetic member 24 need to be replaced, the same size magnetic member can be used for replacement, which simplifies the replacement process and reduces the replacement cost. If the hole diameter of the mounting hole 121 is inconsistent with the hole diameter of the second accommodating cavity 2112, the magnetic member may be subjected to uneven force during connection, which weakens the magnetic attraction between the stirring shaft 1 and the stirring blade 2, and further causes unstable connection.
[0039] Further, the length of the second accommodating cavity 2112 is 60%-70% of the length of the first accommodating cavity 2111, which ensures that the magnetic connection between the first magnetic member 13 and the second magnetic member 24 reaches the best state. A too small length may limit the size of the magnetic member and fail to provide sufficient magnetic force to ensure stable connection between the stirring blade 2 and the stirring shaft 1, thereby increasing the risk of falling off. A too large length may increase the weight and volume of the magnetic member accommodated, thereby affecting the flexibility of the equipment. In addition, when the magnetic member is replaced, a too large length makes the disassembly and installation process more complicated and time-consuming, increasing the complexity and cost of maintenance.
[0040] Further, the connecting head 12 is provided with a limiting block 122, and the limiting block 122 is annularly arranged on the outer wall of the connecting head 12. Specifically, the limiting block 122 is arranged circumferentially along the outer wall of the connecting head 12 and is integrally formed with the connecting head 12. When one end of the connecting head 12 is sleeved on the connecting rod 11, the limiting block 122 can prevent the connecting head 12 from being excessively installed into the connecting rod 11, that is, when the connecting head 12 reaches the predetermined installation position, the limiting block 122 will contact the edge of the connecting rod 11, thereby preventing the connecting head 12 from continuing to be installed, preventing the first magnetic member 13 from contacting and being attracted to the second magnetic member 24 due to the excessive installation of the connecting head 12 into the connecting rod 11, thereby preventing the stirring blade 2 from being fixed on the stirring shaft 1, causing the stirring blade 2 to loosen or fall off. It should be noted that in other embodiments, the number of limiting blocks 122 can be multiple, and the limiting blocks 122 are uniformly arranged on the outer wall of the connecting head 12.
[0041] Further, the stirring blade further comprises a first blade 22 for stirring the food material and a second blade 23 for crushing the food material, the first blade 22 and the second blade 23 are arranged along the circumference of the mounting portion. The first blade 22 and the second blade 23 are mounted on the mounting portion 21, the first blade 22 is used for stirring the food material, and the second blade 23 is used for crushing the food material. When the stirring blade 2 moves downward into the cup 4 of the ice cream machine, the first blade 22 stirs the food material by rotating, and the second blade 23 cuts and crushes the food material. In this way, one stirring blade can realize different processing methods for the food material, so as to make different kinds of desserts, improve the use efficiency of the ice cream machine, and realize the diversification of the function of the stirring assembly.
[0042] Further, the first blade 22 and the second blade 23 are both a plurality of blades, and the plurality of first blades 22 and the plurality of second blades 23 are arranged alternately. In this embodiment, the plurality of first blades 22 and the plurality of second blades 23 are arranged alternately, so that the stirring blade 2 can simultaneously perform stirring and crushing operations during rotation, ensuring the uniformity of the mixing of the food material and improving the stirring efficiency. In this embodiment, the first blade 22 and the second blade 23 are both provided with two blades, the two first blades 22 are arranged radially opposite to each other, the two second blades 23 are arranged radially opposite to each other, and the first blade 22 and the second blade 23 are both arranged obliquely. In the stirring direction of the food material, one side of the first blade 22 gradually inclines upward to the other side, which can turn the food material at the bottom of the cup to the top, and one side of the second blade 23 gradually inclines downward to the other side, which can form a downward cutting force during stirring, so that the food material is crushed at the bottom of the cup 4. Through the staggered and inclined arrangement of the first blade 22 and the second blade 23, the dead angle of the food material in the cup 4 can be reduced, and all the food material can be fully stirred and crushed.
[0043] Further, the cutting edge of the first blade 22 is arc-shaped. During stirring, the arc-shaped cutting edge can better cut into the food material. When the food material is relatively viscous or the block is relatively large, the arc-shaped cutting edge can reduce the stirring resistance and make the stirring process more smooth. Further, the cutting edge of the second blade 23 is serrated. Through the serrated cutting edge, the shearing force of the stirring assembly on the food material can be increased, so as to cut the food material into smaller particles, thereby ensuring that the food material is fully crushed.
[0044] The utility model discloses an embodiment further proposes a kind of ice cream machines, including above-mentioned stirring subassembly, cup 4 and machine body 3, the cup 4 is fixed in the machine body 3, the driving element is equipped in the machine body 3, the driving element is connected with the stirring subassembly, to drive the stirring subassembly rotates in cup 4 or relative to the machine body 3 lifts and falls.In this embodiment, cup 4 can be detachably fixed in machine body 3, stirring subassembly is driven stirring subassembly to rotate or lift and fall by driving element arranged in machine body 3, so that stirring subassembly can be inserted into cup 4 to stir or make stirring shaft 1 and stirring knife 2 complete tool-feeding or tool-withdrawal.It needs to be explained that, in this embodiment, driving element is composed of synchronous belt, synchronous wheel and motor.
[0045] The above-mentioned is only optional embodiment of the utility model, and not therefore limit the patent range of the utility model, is equivalent to the structure transformation made in the utility model construction idea of the utility model, or direct / indirectly applied in other related technical fields using the utility model specification and attached drawing contents, and is included in the patent protection range of the utility model.
