Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] Example 1

[0038] like Figures 1 to 7 As shown, the waterproof milk frother of this embodiment 1 includes a first housing 1, a second housing 2, an end cap 3, a waterproof component 6, a connector 7, and a stirring rod 8. The first housing 1 and the second housing 2 are detachably connected. When combined in this detachable manner, the first housing 1 and the second housing 2 form a sealed cavity. A battery 4 and a motor 5 are arranged sequentially from top to bottom within the cavity. A first mounting base for mounting the battery 4 is symmetrically arranged at the upper part of the cavity, and a second mounting base for mounting the motor 5 is symmetrically arranged at the lower part. The battery 4 and the motor 5 can be securely installed within the cavity via the first and second mounting bases, respectively. The end cap 3 is detachably connected to the bottom of the first housing 1 and the second housing 2, further enhancing the overall sealing. The detachable connection between the first housing 1 and the second housing 2, as well as the detachable design of the end cap 3, allows users to easily maintain and clean the milk frother.

[0039] Furthermore, an installation hole is provided at the bottom of the end cap 3, and the connector 7 is inserted into the installation hole. A waterproof protrusion is provided at the lower end of the connector 7, and the top surface of the waterproof protrusion abuts against the outside of the installation hole. By setting the connector 7, the first waterproof barrier is formed, which can prevent most of the water from entering the shell.

[0040] At this time, the output end of the motor 5 is connected to the motor shaft 51, the motor shaft 51 passes through the waterproof part 6 downwards, the top of the stirring rod 8 extends into the connector 7 and is connected to the bottom of the motor shaft 51, and the bottom of the stirring rod 8 is provided with a stirring head 9. When the motor 5 starts, the motor shaft 51 drives the stirring rod 8 to rotate, which in turn drives the stirring head 9 to perform stirring operation.

[0041] The waterproof component 6 is connected to the bottom of the first housing 1 and the second housing 2. Waterproof sheets 63 are symmetrically arranged on both sides of the waterproof component 6. When the end cap 3 is installed with the first housing 1 and the second housing 2, the waterproof sheets 63 are pressed into the assembly gap between the end cap 3 and the first housing 1 and the second housing 2, which can form a second waterproof barrier to further prevent water penetration and enhance the waterproof performance of the assembly gap, ensuring that the milk maker can work normally in a humid environment.

[0042] Specifically, the waterproof component 6 includes a base plate 61 and an upper boss 62. The upper boss 62 is fixedly connected to the base plate 61 and has an inner cavity 65. The upper boss 62 is engaged with the bottom end of the first housing 1 and the second housing 2. A through hole 64 is opened in the middle of the upper boss 62, which is connected to the inner cavity 65. The motor shaft 51 is engaged with the through hole 64. The waterproof sheet 63 is symmetrically connected to both sides of the base plate 61.

[0043] Preferably, the base plate 61 is a waterproof pad, and the waterproof sheet 63 is integrally formed with the waterproof pad, which can enhance the integrity and waterproof performance of the waterproof component 6. Preferably, the waterproof sheet 63 is made of an elastically deformable material, such as silicone or rubber, which can adapt to the size and shape of different assembly gaps to ensure a tight fit. When the end cap 3 is installed with the first housing 1 and the second housing 2, the waterproof sheet 63 is compressed and deformed, tightly fitting into the assembly gap to form an effective waterproof barrier.

[0044] In addition, a charging port 12 is provided on the top of the first housing 1 for charging the milk maker, and a control switch 11 is provided on the outer wall to control the opening and closing of the motor 5 for user convenience.

[0045] Example 2

[0046] like Figures 8 to 16 As shown, the difference between this embodiment 2 and embodiment 1 is that the waterproof component 6 includes a base plate 61, an upper boss 62, and a lower seat 66. The upper boss 62 and the lower seat 66 are fixedly connected to the upper and lower ends of the base plate 61, respectively. The upper boss 62, the base plate 61, and the lower seat 66 are hollow and have an inner cavity 65. The outline of the inner cavity 65 is a smoothly transitioned stepped structure. This arrangement is equivalent to the function of multiple waterproof gaskets, which can more effectively block water penetration and achieve a better waterproof effect. The upper boss 62 is connected to the bottom end of the first housing 1 and the second housing 2 to ensure the sealing of the assembly. A through hole 64 is opened in the middle of the upper boss 62, which is connected to the inner cavity 65. The motor shaft 51 is connected to the through hole 64. The outer side wall of the lower seat 66 is adapted to the inner side wall of the end cover 3. When the end cover 3 is installed in place, a tight sealing structure is formed between the lower seat 66 and the end cover 3. The waterproof sheet 63 is symmetrically connected to both sides of the base plate 61.

[0047] A connecting spring 52 is connected between the motor shaft 51 and the stirring rod 8. The two ends of the connecting spring 52 are respectively sleeved on the motor shaft 51 and the stirring rod 8. The connecting spring 52 not only acts as a buffer but also effectively prevents the stirring rod 8 from shaking during operation, improving the stability and efficiency of stirring, allowing the milk frother to complete the stirring task more efficiently. Preferably, the top end of the connecting spring 52 abuts against the waterproof component 6, and the bottom end is fitted into the plug-in component 53. The connector 7 includes a sleeve and a waterproof boss that are fixedly connected to each other, and the plug-in component 53 is snap-fitted into the sleeve.

[0048] This utility model of a milk frother with a waterproof structure enhances its waterproof performance by incorporating waterproof components, effectively preventing water from entering the motor and thus avoiding battery damage and leakage risks. It not only ensures that the milk frother can maintain its normal function during washing after use, but also greatly improves the product's durability and safety, providing users with a more convenient and reassuring user experience. Its overall structural design is reasonable, easy to use, and highly practical.

[0049] 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.
