Description

Technical Field

[0001] This utility model relates to the field of milk frother technology, and in particular to a detachable milk frother connection structure. Background Technology

[0002] Milk frothers, as convenient mixing tools, are widely used in the preparation of dairy products and other foods, effectively reducing the burden of mixing operations. Currently, most milk frothers on the market feature detachable mixing rods. This not only facilitates thorough cleaning of the mixing rod, ensuring food safety, but also allows for flexible replacement of the mixing head according to different usage scenarios. However, existing connections between the mixing rod and the motor often use a snap-fit ​​method. For example, the multi-functional detachable electric mixing and cleaning device with Chinese patent number CN206044443U connects the motor and functional components via a connector. The functional components have a detachable elastic connector adapted to the connector. This structure has significant drawbacks: after repeated insertion and removal, the snaps are prone to aging and loosening, leading to unstable connection and easy detachment of the mixing rod. Furthermore, it requires strict dimensional accuracy in production; dimensional deviations can easily cause product defects. Utility Model Content

[0042] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0043] Example 1

[0044] like Figures 1 to 12 As shown, the detachable milk maker connection structure of this embodiment 1 includes a motor 2, a connector 3, and a stirring rod 4. The output end of the motor 2 is connected to a motor shaft 21, which is responsible for transmitting the rotational power of the motor 2. The motor shaft 21 is detachably connected to the stirring rod 4 through the connector 3. The bottom end of the stirring rod 4 is provided with a stirring head 5 for actual stirring operation. The connector 3 includes a connector 31, a connecting rod 32, and an elastic fastener 33. The upper part of the connecting rod 32 is provided with a groove 36, and the bottom end is fixedly connected to the connector 31. The connector 31 is used to connect with the stirring rod 4. The elastic fastener 33 is fitted into the groove 36 and can tighten the motor shaft 21.

[0045] Specifically, the top of the connector 3 has a first mating hole 34 facing downwards, and the motor shaft 21 is adapted to be installed in the first mating hole 34. The bottom of the connector 3 has a second mating hole 35 facing upwards, and the top of the stirring rod 4 is adapted to be installed in the second mating hole 35. This ensures precise alignment and stable connection between the motor shaft 21 and the stirring rod 4 and the connector 3. The first mating hole 34 and the second mating hole 35 are interconnected, so that the rotational power transmitted by the motor shaft 21 can be smoothly transmitted to the stirring rod 4, ensuring the continuity and efficiency of power transmission.

[0046] The upper part of the connecting rod 32 has symmetrical grooves 36 on both sides. The grooves 36 provide installation space for the elastic fastener 33, so that it can be firmly fixed on the connecting rod 32. The inner wall of the opposite side of the two grooves 36 has a connecting groove 37 in the middle. The connecting groove 37 is connected to the first mating hole 34. The opening of the connecting groove 37 allows the elastic fastener 33 to contact the motor shaft 21 through the connecting groove 37 during installation, and allows it to deform to a certain extent to better hold the motor shaft 21.

[0047] Specifically, the elastic fastener 33 is a rounded rectangular elastic rubber ring with good elasticity and plasticity, which can adapt to changes in the shape and size of the motor shaft 21. Furthermore, the elastic fastener 33 has a fastening through hole 331. The elastic fastener 33 is fixed within the groove 36 and contacts the motor shaft 21 to hold the motor shaft 21 with elastic force. When the elastic fastener 33 is installed in the groove 36 and contacts the motor shaft 21, its elastic force causes the rubber ring to deform and hold the motor shaft 21. Due to the presence of the connecting groove 37, the elastic fastener 33 can open to a certain extent to accommodate the motor shaft 21 and provide a uniform clamping force during the clamping process.

[0048] Preferably, a prismatic edge is provided at the end of the motor shaft 21, and the shape of the first mating hole 34 is adapted to the end of the motor shaft 21. By increasing the contact area and friction, the transmission effect is improved, so that the motor 2 can more effectively transmit power to the stirring rod 4 and improve the stirring efficiency of the milk frother.

[0049] Furthermore, the detachable milk maker connection structure of this embodiment 1 also includes a housing 1, a motor 2 disposed inside the housing 1, an installation hole at the bottom of the housing 1, a connecting rod 32 inserted into the installation hole, and the top surface of the connector 31 abutting against the outside of the installation hole to achieve a seal of the installation hole. Preferably, the cross-section of the connector 31 is an inverted trapezoid, so that the connector 31 can tightly abut against the outside of the installation hole at the bottom of the housing 1 to achieve a good sealing effect, effectively preventing liquid or dust from entering the interior of the housing 1 and protecting key components such as the motor 2 and the battery 7.

[0050] Meanwhile, a control switch 6 is provided on the top of the housing 1 to control the opening and closing of the motor 2. A battery 7 is provided inside the housing 1 and is electrically connected to the motor 2. When not in use, the housing 1 can be placed in the support 8.

[0051] The detachable milk frother connection structure of this embodiment 1 uses a connector 3 and a groove 36 on the connecting rod 32 to hold the motor shaft 21 tightly using the elastic force of the elastic fastener 33. During repeated insertion and removal, the elastic fastener 33 maintains a stable elastic force, ensuring a tight fit between the connecting rod 32 and the motor shaft 21. This improves the connection stability of the milk frother during use, providing users with a more reliable and safer user experience. It effectively avoids safety accidents and food contamination risks that may be caused by the stirring rod 4 falling off. At the same time, the elastic self-adaptive capability of the elastic fastener 33 can still achieve good holding of the motor shaft 21 within a certain dimensional deviation range, reducing the requirements for processing equipment and processes, and reducing product defects caused by dimensional deviations.

[0052] Example 2

[0053] like Figures 13 to 16 As shown, the difference between this embodiment 2 and embodiment 1 is that the upper part of the connecting rod 32 is a two-lobed groove structure. A pair of through slots, namely the first slot 38, are symmetrically opened in the upper part of the connecting rod 32 along the circumference, thus forming a two-lobed groove structure. The elastic fastener 33 is a circular elastic rubber ring. The elastic fastener 33 is fixed in the groove 36. When squeezed by the elastic fastener 33, the two-lobed groove structure can produce elastic deformation, thereby clamping and locking the motor shaft 21 and ensuring a stable and reliable connection.

[0054] At this time, the circular elastic rubber ring, due to its own elasticity and plasticity, can make the connecting rod 32 fit tightly against the motor shaft 21, providing a stable clamping force, ensuring a solid connection between the motor shaft 21 and the stirring rod 4, and preventing loosening or falling off during the stirring process. The design of the two-lobed groove structure allows the connecting rod 32 to form a more uniform force distribution when clamping the motor shaft 21, further enhancing the stability of the connection.

[0055] Meanwhile, the design of the two-slot structure makes the stirring rod 4 easier to install and disassemble. Users only need to align the motor shaft 21 with the first mating hole 34 of the connecting rod 32 and then gently push it so that the elastic fastener 33 can hold the motor shaft 21 to complete the installation. Similarly, when disassembling, only a little force is needed to pull the motor shaft 21 out of the connecting rod 32, which not only simplifies the installation and disassembly process, but also improves the user's operating convenience.

[0056] Example 3

[0057] like Figures 17 to 20As shown, the difference between this embodiment 3 and embodiment 2 is that the upper part of the connecting rod 32 is a four-lobed groove structure. Two pairs of mutually perpendicular through grooves, namely the first groove 38 and the second groove 39, are symmetrically opened along the circumference of the upper part of the connecting rod 32. The two are distributed in a cross shape to form a four-lobed groove structure. The elastic fastener 33 is a circular elastic rubber ring. The elastic fastener 33 is fixed in the groove 36. When squeezed by the elastic fastener 33, the four-lobed groove structure can produce elastic deformation, thereby clamping and locking the motor shaft 21 and ensuring a stable and reliable connection.

[0058] This utility model's detachable milk frother connection structure utilizes a groove in the connecting rod and the elastic force of a fastener to securely hold the motor shaft. During repeated insertion and removal, the fastener maintains stable elasticity, ensuring a tight fit between the connecting rod and the motor shaft. Furthermore, the self-adaptive elasticity of the fastener allows for good gripping of the motor shaft even within a certain dimensional deviation range, reducing product defects caused by dimensional variations. This utility model features a compact overall design, ease of use, and strong practicality.

[0059] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
