Description

Technical Field

[0001] This utility model relates to the field of cold drink equipment, specifically an anti-detachment magnetic suction head for an ice cream machine. Background Technology

[0002] In the structural design of ice cream machines, the blade head, as the core mixing component, usually needs to be detachably connected to the drive shaft so that users can clean and replace the blade head.

[0003] Currently, magnetic connection between the blade and drive shaft is gradually becoming the preferred solution for mid-to-high-end ice cream machines due to its convenience of easy assembly and disassembly without the need for alignment and with one hand. The principle is to place a magnetic component at the end of the drive shaft and an attractive metal or dissimilar magnetic component at the corresponding position on the blade, using magnetic force to achieve quick connection and separation. While this connection method allows for convenient assembly and disassembly, in actual use, the drive shaft may experience axial movement during ice cream machine operation. The blade, relying solely on magnetic force, is easily detached from the drive shaft due to axial forces. Once the blade detaches, it not only causes the ice cream mixing function to fail but may also collide with other components, damaging the equipment and severely impacting the user experience and lifespan of the ice cream machine. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide an anti-detachment magnetic blade for an ice cream machine, in order to solve the problem mentioned in the background art that conventional blades are easily separated from the drive shaft due to the axial force generated by the axial movement of the drive shaft.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-detachment magnetic blade head for an ice cream machine, comprising a drive shaft, a blade head, and a cup lid. The blade head and the drive shaft are detachably connected. The cup lid and the drive shaft are coaxially provided with a silicone sleeve. The silicone sleeve and the cup lid are snap-fitted together, and the silicone sleeve has a support structure for accommodating the blade head.

[0006] Preferably, a magnetic connection part is fixedly installed at one end of the drive shaft, and the cutter head is detachably connected to the drive shaft through the magnetic connection part.

[0007] Preferably, the silicone sleeve and the cup lid are engaged through the cooperation of protrusions and perforations.

[0008] Preferably, the top of the silicone sleeve is integrally formed with a plurality of connecting posts, and the top of the cup lid is provided with insertion holes arranged in a ring array around its axis and adapted to the connecting posts. The side wall of the connecting posts is provided with a stepped portion for preventing slippage.

[0009] Preferably, the support structure is an annular clamping cavity located at the bottom of the silicone sleeve for supporting the cutter head.

[0010] Preferably, the top and bottom of the silicone sleeve are respectively provided with circular holes for the drive shaft and the cutter head to pass through, and a cross groove is provided at the circular hole located on the bottom wall of the annular clamping cavity.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention solves the problem of single magnetic attraction easily falling off due to axial movement of the drive shaft by setting a silicone sleeve at the magnetic connection between the blade head and the drive shaft. The bottom of the silicone sleeve has an annular clamping cavity for supporting the blade head, which forms a stable axial limit for the blade head. In addition, the elastic properties of the silicone material of the silicone sleeve can buffer the working vibration. While making the blade head easy to install and remove, it also improves the stability and reliability of the blade head operation, effectively extends the service life of the components, and ensures the smooth and efficient mixing process of the ice cream machine.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4This utility model provides a technical solution: an anti-detachment magnetic blade for an ice cream machine, comprising a drive shaft 1, a blade 2, and a lid 3. The blade 2 and the drive shaft 1 are detachably connected. The drive shaft 1 serves as the power output carrier, with its end furthest from the blade 2 connected to the output shaft of a drive motor built into the ice cream machine via a coupling or keyway structure. The motor transmits torque to the drive shaft 1 through a reduction gear set (a conventional configuration in the prior art), enabling the drive shaft to rotate around its own axis. The use of a magnetic connection part to achieve the detachable connection between the blade and the drive shaft satisfies the user's need for convenient daily disassembly and cleaning, while also ensuring the stability of the basic connection through magnetic force. A magnetic connection part 5 is fixedly installed at one end of the drive shaft 1, and the blade 2 is detachably connected to the drive shaft 1 via the magnetic connection part 5. The magnetic connection part 5 is fixedly mounted at the end of the drive shaft 1 closest to the blade 2. This magnetic connection part uses neodymium iron boron permanent magnet material (the magnetic parameters have been optimized to ensure both reliable adsorption and easy manual disassembly). The corresponding position of the cutter head 2 is inlaid with a magnetically attracted metal sheet or another magnet of opposite polarity, which achieves a detachable connection with the drive shaft 1 through magnetic attraction. The advantage of this design is that it makes it easy to install and remove the cutter head 2, and the user can complete the operation of picking up and putting down the cutter head 2 with one hand.

[0020] A silicone sleeve 4 is coaxially mounted on the cup lid 3 and the drive shaft 1. The cup lid 3 serves as a fixed base component, sealingly engaging with the edge of the ice cream machine's cup (not shown in the figure), while its central area remains coaxial with the drive shaft 1. The silicone sleeve 4 and the cup lid 3 are snap-fitted together through a combination of protrusions and holes. The top of the silicone sleeve 4 has several integrally formed connecting posts 7, with at least three connecting posts 7. The top of the cup lid 3 has insertion holes arranged in a circular array around its axis, which are adapted to the connecting posts 7. The sidewalls of the connecting posts 7 have stepped portions 8 for preventing detachment, and the stepped portions 8 form an interference fit with the insertion holes on the cup lid 3. During assembly, the silicone sleeve 4 presses the connecting post 7 into the insertion hole through the elastic deformation of the silicone. The stepped part 8 forms a mechanical lock with the edge of the insertion hole, preventing the silicone sleeve 4 from axially falling off. The silicone sleeve 4 also has a support structure for accommodating the blade head 2. The support structure is an annular clamping cavity at the bottom of the silicone sleeve 4 for supporting the blade head 2. The top and bottom of the silicone sleeve 4 are respectively provided with circular holes for the drive shaft 1 and the blade head 2 to pass through. A cross groove 6 is provided at the circular hole located on the bottom wall of the annular clamping cavity. The outer wall of the blade head 2 is provided with protrusions (such as an annular flange or several circumferentially distributed protrusions). When the blade head 2 passes through the circular hole at the bottom of the silicone sleeve 4 and is attracted and connected to the drive shaft 1 through the magnetic connection part 5, the protrusion of the blade head 2 can just rest on the edge of the circular hole at the bottom of the annular clamping cavity, thereby realizing the support of the blade head 2 by the silicone sleeve 4, avoiding the blade head 2 from falling off due to factors such as the axial movement of the drive shaft 1, and ensuring the stable and reliable stirring function of the ice cream machine.

[0021] This application provides a silicone sleeve 4 at the magnetic connection between the blade head 2 and the drive shaft 1. The bottom of the silicone sleeve 4 has an annular clamping cavity for supporting the blade head 2, which provides a stable axial limit for the blade head 2. This solves the problem that a single magnetic connection is prone to falling off due to the axial movement of the drive shaft 1. Furthermore, the elastic properties of the silicone material in the silicone sleeve 4 can buffer working vibrations. This not only makes it easier to install and remove the blade head 2, but also improves the stability and reliability of the blade head 2's operation, effectively extends the service life of the components, and ensures the smooth and efficient mixing process of the ice cream machine.
