Description

Technical Field

[0001] This utility model relates to the field of food preparation appliances, and in particular to a portable ice cream machine. Background Technology

[0002] With the development of technology and people's pursuit of a high quality of life, food preparation appliances have flourished and spawned numerous varieties. For example, a portable food processor disclosed in Chinese invention patent application 2025107364219 can crush ice cubes; at the same time, based on its working principle, it can also be used to make ice cream.

[0003] Modern home food processors are increasingly designed for miniaturization and lightweight construction for easy storage when not in use. However, in existing technologies, such as the portable food processors mentioned above, the motor and gearbox are typically integrated into the main unit. To ensure a comfortable grip, the diameter of the main unit needs to be as small as possible. This smaller diameter necessitates a vertical arrangement of the motor and gearbox, resulting in a longer overall length. Such a longer main unit causes inconvenience during packaging, transportation, and storage. Therefore, improvements to existing technology are necessary to address this issue. Utility Model Content

[0004] The purpose of this invention is to provide a portable ice cream machine that addresses the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides a portable ice cream machine, including a base, a container, and a blade. The container is detachably connected to the bottom of the base. A vertically sliding blade shaft is installed inside the base, extending from the bottom of the base and into the container. The blade is mounted at the bottom of the blade shaft and rotated by it. The blade shaft can rise and fall relative to the base. A spring is installed between the blade shaft and the base, causing the blade shaft to tend to rise. The machine also includes a handle and a speed reduction assembly. The speed reduction assembly is detachably connected to the base and can rise and fall relative to it. The handle is detachably connected above the speed reduction assembly. A motor is installed inside the handle. After the handle is connected to the speed reduction assembly, the motor drives the blade shaft to rotate via the transmission of the speed reduction assembly.

[0006] Furthermore, a first power output head is provided at the bottom of the handle, and the motor drives the first power output head to rotate; the reduction assembly is provided with an upwardly extending drive shaft, the drive shaft is driven by a reduction gear set, and the reduction gear set is driven by a second power output head; when the reduction assembly is connected to the machine base, the second power output head is driven by the cutter shaft; when the handle is connected to the reduction assembly, the first power output head is driven by the drive shaft.

[0007] Furthermore, the deceleration assembly is provided with an upward-opening mounting cavity, and the bottom of the grip is provided with a mounting section, which is embedded into the mounting cavity to connect the grip with the deceleration assembly.

[0008] Furthermore, an inclined connecting pair is provided between the cavity wall of the mounting cavity and the side wall of the mounting section, and an elastic positioning pair is also provided between the cavity wall of the mounting cavity and the side wall of the mounting section. When the mounting section and the mounting cavity are connected in place by means of the inclined connecting pair, the elastic positioning pair makes the mounting cavity and the mounting section relatively positioned.

[0029] The embodiments of this utility model are described in detail below.

[0030] In this embodiment, unless otherwise explicitly specified and limited, terms such as "set in," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through one or more intermediate media. Those skilled in the art can understand the specific meaning of these terms in this embodiment based on the specific circumstances. The directional terms appearing in this embodiment are for the purpose of better describing the characteristics of the features and the relationships between them. It should be understood that when the placement direction of this embodiment changes, the direction of the characteristics of the features and the relationships between them also changes accordingly. Therefore, directional terms do not constitute an absolute limitation on the characteristics of the features and the relationships between them in space, but only a relative limitation.

[0031] This utility model provides a portable ice cream machine, such as Figures 1 to 7 As shown, it includes a base 1, a container 2, and a cutter 3. The container 2 is detachably connected to the bottom of the base 1. A vertically sliding cutter shaft 11 is installed inside the base 1, extending from the bottom of the base 1 and into the container 2. The cutter 3 is mounted on the bottom of the cutter shaft 11 and is driven to rotate by the cutter shaft 11. The cutter shaft 11 can be raised and lowered relative to the base 1, so that the cutter 3 can rotate and move vertically inside the container 2 to meet the needs of making ice cream. A spring 12 is installed between the cutter shaft 11 and the base 1. The spring 12 causes the cutter shaft 11 to tend to rise, that is, when the cutter shaft 11 is not pressed down, the cutter shaft 11 will automatically rise. At the same time, the cutter shaft 11 also drives the cutter 3, as well as the handle 4 and the deceleration assembly 5 mentioned below, to rise together.

[0032] This portable ice cream machine also includes a handle 4 and a reduction gear 5. The reduction gear 5 is detachably connected to the base 1 and can be raised and lowered relative to the base 1. The handle 4 is detachably connected above the reduction gear 5. A motor 41 is installed inside the handle 4. After the handle 4 is connected to the reduction gear 5, the motor 41 drives the cutter shaft 11 to rotate by means of the transmission of the reduction gear 5.

[0033] Based on the above structural design, this portable ice cream machine separates the motor 41 and the reduction gear 5 into two parts, which are assembled when in use and disassembled when not in use. This design allows the handle 4 to be shortened, making it convenient for packaging, transportation and storage. In addition, when the reduction gear 5 is damaged, the user can replace only the reduction gear 5 without replacing the entire handle 4.

[0034] It should be noted that a safety mechanism for locking the cup 2 is also provided in the base 1 so that the cup 2 will not fall off when the ice cream machine is working. The safety mechanism is prior art, and can be found in Chinese invention patent application 2025107364219. Therefore, the structure of the safety mechanism will not be described in this application.

[0035] In this embodiment, a first power output head 42 is provided at the bottom of the grip 4, and the motor 41 drives the first power output head 42 to rotate; the reduction assembly 5 is provided with an upwardly extending transmission shaft 51, which is connected to a reduction gear set, and the reduction gear set is connected to a second power output head 52; when the reduction assembly 5 is connected to the machine base 1, the second power output head 52 is connected to the cutter shaft 11; when the grip 4 is connected to the reduction assembly 5, the first power output head 42 is connected to the transmission shaft 51. Based on the above structural configuration, after the reduction assembly 5 is installed on the machine base 1 and the grip 4 is installed on the reduction assembly 5, a transmission chain is formed, and the motor 41 in the grip 4 can drive the cutter shaft 11 to rotate.

[0036] In this embodiment, the deceleration assembly 5 is provided with an upward-opening mounting cavity 53, and the bottom of the grip 4 is provided with a mounting section 43. The mounting section 43 is embedded in the mounting cavity 53 to connect the grip 4 to the deceleration assembly 5. Preferably, a beveled connecting pair 54 is provided between the cavity wall of the mounting cavity 53 and the side wall of the mounting section 43, and an elastic positioning pair 55 is also provided between the cavity wall of the mounting cavity 53 and the side wall of the mounting section 43. When the mounting section 43 and the mounting cavity 53 are connected in place by means of the beveled connecting pair 54, the elastic positioning pair 55 positions the mounting cavity 53 and the mounting section 43 relative to each other. The beveled connecting pair 54 means that between the cavity wall of the mounting cavity 53 and the side wall of the mounting section 43, one is provided with a beveled connecting structure, and the other is provided with a structure that matches the beveled connecting structure, so as to connect the two by means of the beveled structure. The elastic positioning pair 55 means that between the cavity wall of the mounting cavity 53 and the side wall of the mounting section 43, one is provided with an elastic positioning structure, and the other is provided with a matching structure, so as to achieve relative fixation of the two by means of elasticity. Based on the above structural configuration, the user can detach and assemble the handle 4 from the deceleration assembly 5 by twisting the handle 4 relative to the deceleration assembly 5. At the same time, after installation, the elastic positioning pair 55 takes effect, and the user needs more force to grasp and remove the handle 4.

[0037] In this embodiment, the base 1 is provided with an upward-opening sliding cavity 13, and the cavity wall of the sliding cavity 13 is provided with a vertical slide groove 131. The side wall of the deceleration assembly 5 is provided with a slider 56, and the slider 56 is slidably connected to the vertical slide groove 131. The cooperation between the vertical slide groove 131 and the slider 56 is used to ensure that the deceleration assembly 5 can only slide up and down and cannot rotate.

[0038] In this embodiment, the wall of the sliding cavity 13 is provided with a vertical locking groove 132, and a limiting protrusion 133 is provided at the top of the vertical locking groove 132. The deceleration assembly 5 is provided with a locking block 57, which includes a locking tongue 571 that can extend and retract from the side wall of the deceleration assembly 5. An elastic element is provided between the locking block 57 and the base 1, which causes the locking tongue 571 to tend to extend from the side wall of the deceleration assembly 5. When the extended locking tongue 571 enters the vertical locking groove 132, the limiting protrusion 133 can abut against the locking tongue 571 to restrict the upward movement of the locking tongue 571, and the deceleration assembly 5 cannot disengage from the sliding cavity 13. When the locking tongue 571 retracts, the deceleration assembly 5 can disengage from the sliding cavity 13. Preferably, the locking block 57 also includes an unlocking button 572, and the locking tongue 571 retracts when the unlocking button 572 is pressed. Based on the above structural design, the deceleration assembly 5 can be prevented from accidentally falling off. When the user needs to remove the deceleration assembly 5, the unlocking button 572 must be pressed before removal. More preferably, there are two vertical locking grooves 132 that are 180° apart, and two locking blocks 57 that correspond to the two vertical locking grooves 132 respectively. This structure allows the user to unlock both locking blocks 57 at the same time by pinching with one hand.

[0039] In this embodiment, the tool 3 is a stamped part, and the production cost of the tool 3 with the stamped part structure is relatively low.

[0040] In this embodiment, a speed adjustment component 44 is provided on the top of the handle 4. The speed adjustment component 44 is used to adjust the speed of the motor 41. With the help of this speed adjustment component 44, the speed of the motor 41 can be adjusted, thereby adjusting the speed of the cutter shaft 11 to meet different usage requirements.

[0041] Where there is no conflict, the above embodiments and features can be combined with each other.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the preferred technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of this utility model.
