Description

Technical Field

[0001] This utility model relates to the field of ice cream machine technology, and in particular to a cup lid assembly, a cup assembly, and an ice cream machine. Background Technology

[0002] In traditional blending and grinding devices, the design of the lid is relatively simple. Typically, the lid primarily serves to seal the blending cup, preventing food from splashing out during blending. There are several common methods for assembling the lid and the blade assembly. The first method involves assembling the lid to the housing of the motor that drives the blade, allowing the blade to reach the bottom of the cup when closed to pulverize or blend the materials. However, the blade cannot move vertically within the cup, requiring the user to shake the device or repeatedly open and close the lid to adjust the material's position, which is cumbersome. The second method involves creating a larger hole in the lid for the blade to enter and exit, but this weakens the lid's splash-proof capability. The third method involves detaching the blade from the drive shaft, with a through-hole in the lid allowing only the shaft to pass through. During assembly, the drive shaft must pass through the lid before securing the shaft and blade, a tedious process that carries the risk of cutting the user's fingers. Utility Model Content

[0003] The main objective of this invention is to provide a cup lid assembly, a cup assembly, and an ice cream machine, which aims to provide a cup lid assembly that simplifies the installation of the blade and drive shaft.

[0004] To achieve the above objectives, the cup lid assembly proposed in this utility model is applied to an ice cream machine. The ice cream machine is provided with a drive shaft extending in a vertical direction and a rotary drive assembly for driving the drive shaft to rotate. The cup lid assembly includes: A cover assembly, wherein the middle part of the cover assembly is provided with a central receiving hole, and the central receiving hole is provided with a plurality of elastic retaining beads, the elastic retaining beads being able to extend out of the inner wall of the central receiving hole; A stirring blade assembly includes a blade shaft and a blade body. The blade shaft can extend into the central receiving hole, and the outer wall of the blade shaft can engage with the elastic retaining ball. The blade shaft is detachably connected to the drive shaft, and the blade body is provided with a plurality of blades arranged around the axis of the blade shaft.

[0005] In one embodiment, the elastic retaining bead includes a connecting tube, an elastic element and a retaining bead disposed within the connecting tube, the connecting tube being embedded in the wall of the central receiving hole.

[0006] In one embodiment, the connecting tube is formed with the cover assembly insert, and the outer wall of the connecting tube is provided with an insert connecting structure.

[0007] In one embodiment, the insert engagement structure includes external threads.

[0008] In one embodiment, a snap-fit ​​groove is provided on the outer wall surface of the cutter shaft. The snap-fit ​​groove is arranged around the circumference of the cutter shaft and connected end to end. The snap-fit ​​groove is snapped with the elastic retaining ball.

[0009] In one embodiment, the cover assembly includes a weight-reducing groove circumferentially disposed around the central receiving hole, a receiving protrusion is provided in the weight-reducing groove, a positioning hole is provided in the receiving protrusion, and the elastic retaining bead is disposed in the positioning hole.

[0010] In one embodiment, the sidewall of the receiving protrusion away from the bottom wall of the weight reduction groove is provided with reinforcing ribs, which extend in the vertical direction.

[0011] In one embodiment, the top surface of the cutter shaft is provided with an abutting inclined surface, and the wall of the central receiving hole is provided with a limiting protrusion protruding in the axial direction of the central receiving hole. The limiting protrusion is disposed near the top of the central receiving hole and abuts against the abutting inclined surface.

[0012] This utility model also proposes a cup assembly, comprising: Cup lid assembly; The cup body, with the lid assembly covering the cup body.

[0013] This utility model also proposes an ice cream machine, comprising: A housing, wherein a drive shaft and a cup holder extending in the vertical direction are provided inside the housing; A rotary drive assembly is disposed in the housing and drives the drive shaft to rotate about the axis of the drive shaft; A lifting drive assembly is disposed in the housing and connected to the cup holder, so as to drive the cup holder to move in the vertical direction; The cup assembly is connected to the cup base. The stirring blade assembly has a working state and a standby state within the cup body. In the working state, the blade shaft is away from the central receiving hole, and the blade body moves vertically within the cup body. In the standby state, the blade shaft is located within the central receiving hole and engages with the elastic retaining bead.

[0014] The technical solution of this utility model uses multiple elastic retaining beads in the central receiving hole of the lid assembly to engage with the blade shaft of the mixing blade assembly, thus fixing the mixing blade assembly to the lid assembly. During the assembly of the lid assembly, the drive shaft is inserted into the central receiving hole, allowing it to connect with the blade shaft. When the ice cream machine is started, the cup moves upward relative to the drive shaft. At this time, the drive shaft can connect with the blade shaft in the central receiving hole and exert downward pressure on the blade shaft, causing it to disengage from the elastic retaining beads on the lid assembly and enter the ice cream machine's cup to pulverize the material in the cup. After pulverizing the material in the cup, the cup moves downward relative to the blade shaft, causing the blade shaft to move towards the lid assembly within the cup. When the blade shaft moves into the central receiving hole, it is engaged by the elastic retaining beads. After the blade shaft and lid assembly are assembled, the drive shaft and blade shaft can be detached and removed from the central receiving hole. At this point, the mixing blade assembly can be removed from the ice cream machine along with the lid assembly. This design ensures that the mixing blade assembly only rotates and pulverizes within the cup, and is completely contained and restrained by the lid assembly when not in use. This eliminates the safety hazards of exposed mixing blades found in traditional designs, and also eliminates the risk of cuts from the blades during assembly of the blade shaft and drive shaft. During the pulverization process, the drive shaft extends into the cup through the central receiving hole of the lid assembly. After pulverizing the material, the drive shaft disengages from the central receiving hole, and the mixing blade assembly is held in place by a spring-loaded retaining ball within the central receiving hole. Therefore, the gap between the central receiving hole and the drive shaft remains small, preventing material spillage. During assembly of the lid assembly, mixing blade assembly, and drive shaft, the user simply places the mixing blade assembly into the central receiving hole, and the ice cream machine automatically connects and disconnects the blade assembly from the drive shaft via cup lifting. After pulverization, the blade assembly is removed along with the lid assembly, allowing for cleaning without separate disassembly. This simple operation helps reduce the error rate caused by cumbersome procedures. Attached Figure Description

[0022] This utility model proposes a cup lid assembly.

[0023] Please see Figures 1 to 7 In one embodiment of this utility model, the cup lid assembly 100 is applied to an ice cream machine. The ice cream machine is provided with a drive shaft 700 extending in the vertical direction and a rotation drive assembly 500 for driving the drive shaft 700 to rotate. The cup lid assembly 100 includes: The cover assembly 11 has a central receiving hole 122 in the middle part, and a plurality of elastic retaining beads 123 are provided in the central receiving hole 122. The elastic retaining beads 123 can extend out of the inner wall of the central receiving hole 122. The stirring blade assembly 15 includes a blade shaft 151 and a blade body 152. The blade shaft 151 can extend into the central receiving hole 122, and the outer wall of the blade shaft 151 can be engaged with the elastic retaining ball 123. The blade shaft 151 is detachably connected to the drive shaft 700. The blade body 152 is provided with a plurality of blades 153 arranged around the axis of the blade shaft 151.

[0024] The technical solution of this utility model uses multiple elastic retaining beads 123 in the central receiving hole 122 of the cover assembly 11 to engage with the blade shaft 151 of the stirring blade assembly 15, thereby fixing the stirring blade assembly 15 onto the cover assembly 11. During the assembly of the cup lid assembly 100, the drive shaft 700 is inserted into the central receiving hole 122, allowing the drive shaft 700 to connect with the blade shaft 151. When the ice cream machine is started, the cup body 201 moves upward relative to the drive shaft 700. At this time, the drive shaft 700 can dock with the blade shaft 151 in the central receiving hole 122 and has a downward force on the blade shaft 151. Pressure is applied to disengage the blade shaft 151 from the elastic retaining bead 123 on the lid assembly 11, allowing it to enter the ice cream machine's cup body 201 and pulverize the material within. After pulverizing the material in the cup body 201, the cup body 201 moves downwards relative to the blade shaft 151, causing the blade shaft 151 to move closer to the lid assembly 11 within the cup body 201. When the blade shaft 151 reaches the central receiving hole 122, it is engaged by the elastic retaining bead 123. After the blade shaft 151 and the lid assembly 11 are assembled, the drive shaft 700 and the blade shaft 151 can be detached and removed from the central receiving hole 122. At this point, the mixing blade assembly 15 can be removed from the ice cream machine along with the lid assembly 11. This design ensures that the mixing blade assembly 15 only performs its rotational crushing function within the cup body 201. When not in operation, it is completely contained and restrained by the cover assembly 11, eliminating the safety hazard of the exposed mixing blade assembly 15 in traditional designs. Specifically, it eliminates the risk of being cut by the blades 153 during the assembly of the blade shaft 151 and the drive shaft 700. Furthermore, during the crushing process of the mixing blade assembly 15, the drive shaft 700 extends into the cup body 201 through the central receiving hole 122 of the cover assembly 11. After the mixing blade assembly 15 crushes the material, the drive shaft 700 disengages from the central receiving hole 122, and the mixing blade assembly 15 is held in place by the elastic retaining ball 123 within the central receiving hole 122. Therefore, the gap between the central receiving hole 122 and the drive shaft 700 remains small, preventing material spillage. During the assembly of the lid assembly 11, the mixing blade assembly 15, and the drive shaft 700, the user only needs to snap the mixing blade assembly 15 into the central receiving hole 122, and the ice cream machine can automatically dock and separate the blade assembly from the drive shaft 700 by raising and lowering the cup body 201; after mixing, the blade assembly is removed as a whole with the lid assembly 11, and can be cleaned without disassembling the blade assembly separately. Its operation is simple and helps to reduce the error rate caused by complicated steps.

[0025] In one embodiment, the elastic retaining bead 123 includes a connecting tube 125, an elastic element 126 disposed within the connecting tube 125, and a retaining bead 127. The connecting tube 125 is embedded in the wall of the central receiving hole 122. The retaining bead 127 is abutted by the elastic element 126 within the connecting tube 125 and abuts against the end face of the connecting tube 125. The retaining bead 127 is movable within the connecting tube 125. Further, a retaining groove 159 is provided on the outer wall surface of the cutter shaft 151. The retaining groove 159 is arranged around the circumference of the cutter shaft 151 and connected end to end. The retaining groove 159 engages with the elastic retaining bead 123. When the elastic retaining bead 123 engages with the side wall of the retaining groove 159 on the cutter shaft 151, the retaining bead 127 is located at the opening of the connecting tube 125 and extends into the retaining groove 159. At this time, the retaining bead 127 can move within the retaining groove 159, that is, the cutter shaft 151 can rotate around the axis of the central receiving hole 122 within the central receiving hole 122. When the retaining bead 127 is pressed by the end face of the retaining groove 159 and moves into the connecting tube 125, the retaining bead 127 presses against the elastic element 126. At this time, the retaining bead 127 disengages from the retaining groove 159, and the cutter shaft 151 can be removed from the cover assembly 11. In other embodiments, there may be multiple retaining grooves 159, spaced apart around the circumference of the cutter shaft 151, and each corresponding to one of the elastic retaining beads 123.

[0026] In one embodiment, the connecting tube 125 is embedded in the cap assembly 11, and the outer wall of the connecting tube 125 is provided with an insert engagement structure 125a. Further, the insert engagement structure 125a includes an external thread 125b. This helps to enhance the connection stability between the connecting tube 125 and the cap assembly 11. In other embodiments, the insert engagement structure 125a includes a plurality of annular protrusions spaced apart along the length of the connecting tube 125 by the external thread 125b.

[0027] In one embodiment, the cover assembly 11 includes a weight-reducing groove 128 circumferentially disposed around the central receiving hole 122. The weight-reducing groove 128 has a receiving protrusion 128a, and the receiving protrusion 128a has a positioning hole 128b. A resilient retaining bead 123 is disposed in the positioning hole 128b. The weight-reducing groove 128 effectively reduces the weight of the cover assembly 11 by reducing the amount of material used in its production, thus making the cover assembly 11 lightweight and reducing production costs. The receiving protrusion 128a in the weight-reducing groove 128 is used to engage with the insert of the connecting tube 125, thereby ensuring stable installation with the resilient retaining bead 123 while reducing the weight of the cover assembly 11. In other embodiments, the weight-reducing groove 128 may not be provided.

[0028] In one embodiment, a reinforcing rib 128c is provided on the side wall of the receiving protrusion 128a away from the bottom wall of the weight-reducing groove 128. The reinforcing rib 128c extends in the vertical direction to further strengthen the support structure of the receiving protrusion 128a within the weight-reducing groove 128, making the elastic retaining ball 123 more securely fixed to the cover assembly 11. This effectively reduces the probability that the receiving protrusion 128a will deform or twist within the weight-reducing groove 128 or develop cracks that expose the connecting tube 125 after prolonged use. In other embodiments, the reinforcing rib 128c may not be provided to further reduce production costs.

[0029] In one embodiment, the top surface of the blade shaft 151 is provided with an abutting inclined surface 160, and the wall of the central receiving hole 122 is provided with a limiting protrusion 129 protruding in the axial direction of the central receiving hole 122. The limiting protrusion 129 is disposed near the top of the central receiving hole 122 and abuts against the abutting inclined surface 160, so as to prevent the blade shaft 151 from being unable to detach from the drive shaft 700 during the process of the cover assembly 11 disengaging from the drive shaft 700, and to prevent the blade shaft 151 from coming out of the central receiving hole 122 upward. The abutting inclined surface 160 on the blade shaft 151 helps to allow the stirring blade assembly 15 to be assembled in cover assemblies 11 of different sizes, thereby adapting to the different diameters of the central receiving holes 122 on cover assemblies 11 of different sizes. In other embodiments, the abutting inclined surface 160 may not be provided.

A rotary drive assembly 500 is located in the housing 300 and drives the drive shaft 700 to rotate around its axis. A lifting drive assembly 600 is located in the housing 300 and connected to the cup holder 400 to drive the cup holder 400 to move vertically. The cup assembly 200 is connected to the cup holder 400. The stirring blade assembly 15 has a working state and a standby state within the cup body 201. In the working state, the blade shaft 151 is away from the central receiving hole 122, and the blade body 152 moves vertically within the cup body 201. In the standby state, the blade shaft 151 is located at the central receiving hole 122 and is engaged with the elastic retaining bead 123. That is, in the ice cream machine proposed in this utility model, the cup assembly 200 is driven by the lifting drive assembly 600 to move vertically, and the drive shaft 700 is driven by the rotary drive assembly 500 to rotate the stirring blade assembly 15. As the cup assembly 200 moves up and down, the stirring blade assembly 15 can detach from the lid assembly 11 and enter the cup body 201 during operation, and assemble with the lid assembly 11 during standby. This process is simple to operate and does not require manual operation, avoiding hand injuries from the stirring blade assembly 15. It also has good anti-splash performance, making the ice cream machine efficient, safe and easy to use.
