Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0033] To further understand the content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0034] Firstly, referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 This utility model provides a suspended milk frother, including a milk tank 1, a top cover 2, a foaming device 4, and a suspension device 5. The top cover 2 is detachably mounted on the upper opening of the milk tank 1 via a mounting assembly 3. The foaming device 4 is disposed on the top cover 2. The suspension device 5 includes a driving member 51, an insert 52, and a resetting member 53. One end of the driving member 51 is located inside the top cover 2, and the other end of the driving member 51 protrudes from the top cover 2. One end of the insert 52 is located inside the top cover 2, and one end of the insert 52 is connected to the driving member 51. The other end of the insert 52 protrudes from the top cover 2 and has a limiting part 521. The resetting member 53 is disposed inside the top cover 2, one end of the resetting member 53 abuts against the insert 52, and the other end of the resetting member 53 abuts against the inner wall of the top cover 2 or the foaming device 4.

[0035] In practical applications, the coffee machine has a socket that matches the shape of the insert 52. When the suspended milk frother is installed on the coffee machine, the other end of the insert 52 passes through the socket, causing the limiting part 521 to engage with the socket on the coffee machine. When the suspended milk frother needs to be removed from the coffee machine, press the drive member 51 to align the limiting part 521 with the socket, and then pull the suspended milk frother away from the coffee machine to remove it. When the suspended milk frother needs to be installed back on the coffee machine, simply align the insert 52 with the socket and insert it. During insertion, the reset member 51 is compressed. After the insert 52 is fully inserted, the compressed elasticity of the reset member 51 causes the limiting part 521 to engage with the socket on the coffee machine, thus installing the suspended milk frother. Specifically, the reset member 53 can be a spring.

[0036] The above technical solution facilitates the quick installation or removal of the hanging milk frother from the coffee machine.

[0037] Please refer to the following: Figure 6In some preferred embodiments, the mounting assembly 3 includes a movable plate 31, a rotating plate 32, a first elastic element 33, and a second elastic element 34. The movable plate 31 is slidably disposed within the upper cover 2, and one end of the movable plate 31 has a movable pressing portion 311 and a first latching portion 312 that protrude from the upper cover 2. The rotating plate 32 is rotatably disposed within the upper cover 2 via a pivot, and one end of the rotating plate 32 has a second latching portion 321 that protrudes from the upper cover 2; the other end of the rotating plate 32 abuts against the other end of the movable plate 31. One end of the first elastic element 33 abuts against the inner sidewall of the upper cover 2, and the other end of the first elastic element 33 abuts against the movable plate 31. One end of the second elastic element 34 abuts against the inner sidewall of the upper cover 2, and the other end of the second elastic element 34 abuts against the other end of the rotating plate 32. When the upper cover 2 is installed at the upper opening of the milk box 1, the first latching portion 312 and the second latching portion 321 respectively extend into two opposing fixed locking positions 11 opened on the sidewall of the milk box 1.

[0038] In practical application, when the top cover 2 is installed at the upper opening of the milk box 1, the first latching part 312 and the second latching part 321 respectively extend into the two fixed locking positions 11, so that the top cover 2 is connected to the milk box 1 as one unit. When it is necessary to add milk to the milk box 1 or to clean it, press the movable pressing part 311, so that the movable plate 31 moves towards the rotating plate 32. During the movement of the movable plate 31, the first latching part 312 moves from its corresponding fixed locking position 11 to the top cover 2. At the same time, the movable plate 31 pushes the other end of the rotating plate 32 to rotate the rotating plate 32, so that the second latching part 32 at one end of the rotating plate 32 moves from its corresponding fixed locking position 11 to the top cover 2. At this time, the top cover 2 can be removed from the upper opening of the milk box 1. Since the first elastic element 33 and the second elastic element 34 are compressed when the movable plate 32 and the rotating plate 32 rotate, the top cover 2 can be removed from the upper opening of the milk box 1. After removal, the movable plate 32 and the rotating plate 32 will return to their original shape under the elastic force of the first elastic member 33 and the second elastic member 34, that is, the movable pressing part 311, the first latching part 312 and the second latching part 321 are all exposed on the upper cover 2. When it is necessary to reinstall the upper cover 2 at the upper opening of the milk box 1, the upper cover 2 can be directly aligned with the upper opening of the milk box 1 and moved relative to each other to reinstall the upper cover 2 at the upper opening of the milk box 1. Alternatively, the movable pressing part 311 can be pressed to align the upper cover 2 with the upper opening of the milk box 1 and move relative to each other. After the relative movement is in place, the movable pressing part 311 can be stopped to reinstall the upper cover 2 at the upper opening of the milk box 1. Specifically, the first elastic member 33 and the second elastic member 34 can both be springs.

[0039] In some preferred embodiments, the movable plate 31 is provided with a guide hole 313, and the upper cover 2 is provided with a guide rod 21, which is located inside the guide hole 313. This technical solution enables the movable plate 31 to move precisely with the cooperation of the guide hole 313 and the guide rod 21, thereby ensuring that the first latching part 312 and the second latching part 321 simultaneously disengage from their corresponding fixed positions 11.

[0040] In some preferred embodiments, both the movable plate 31 and the rotating plate 32 have receiving grooves 35 at their other ends. The other end of the first elastic member 33 is located in the receiving groove 35 on the movable plate 31, and the other end of the second elastic member 34 is located in the receiving groove 35 at the other end of the rotating plate 32. This technical solution not only facilitates the installation of the first elastic member 33 and the second elastic member 34, but also allows for the constraint of the first elastic member 33 and the second elastic member 34, ensuring that the elastic force is directed along their axial direction.

[0041] In some preferred embodiments, the suspension device 5 further includes a fixing plate 54. The fixing plate 54 is fixedly disposed inside the upper cover 2, the insert 52 is movably disposed on the fixing plate 54, and the other end of the reset member 53 abuts against the fixing plate 54. This technical solution allows the insert 52 to accurately reset under the action of the reset member 53 without being driven by the driving member 51, thereby ensuring a secure connection when the suspended milk frother is installed on the coffee machine, with the limiting part 521 precisely engaging with the limiting groove.

[0042] In some preferred embodiments, the insert 52 is provided with a groove 522, and one end of the reset member 53 is located within the groove 522. This technical solution not only facilitates the installation of the reset member 53, but also effectively constrains one end of the reset member 53, preventing radial displacement of the reset member 53.

[0043] In some preferred embodiments, the foaming device 4 includes a frother 41, a steam inlet pipe 42, a foam outlet pipe 43, and a milk inlet pipe 44. The frother 41 is disposed inside the upper cover 2 and has a steam inlet 411, an air inlet 412, a milk inlet 413, and a foam outlet 414. One end of the steam inlet pipe 42 extends into the upper cover 2 and connects to the steam inlet 411, while the other end of the steam inlet pipe 42 protrudes from the upper cover 2. One end of the foam outlet pipe 43 extends into the upper cover 2 and connects to the foam outlet 414, while the other end of the foam outlet pipe 43 protrudes from the upper cover 2. One end of the milk inlet pipe 44 is connected to the milk inlet 413. The other end of the milk inlet pipe 44 extends into the interior of the milk tank 1. The air inlet 412 communicates with the outside. In practical applications, the high-temperature steam generated by the coffee machine enters the frother 41 through the steam inlet pipe 42 and the steam inlet 411. Outside air enters the frother 41 through the air inlet 412. Under the Venturi effect, the milk in the milk tank 1 enters the frother 41 through the milk inlet pipe 44 and the milk inlet 413 and mixes with the high-temperature steam and air to form milk foam. The milk foam is discharged from the foam outlet pipe 43 through the foam outlet 414.

[0044] In some preferred embodiments, an air intake adjustment knob 415 is provided at the air inlet 412, with at least a portion of the air intake adjustment knob 415 exposed above the upper cover 2. In practical applications, by adjusting the air intake adjustment knob 415, the amount of air entering the air inlet 412 can be changed to alter the size and texture of the milk foam.

[0045] In some preferred embodiments, the outer wall of the upper cover 2 has a push rod 22, which is arranged parallel to the insert 52. In specific applications, the coffee machine is equipped with a micro switch. When the suspended milk frother is installed on the coffee machine, the push rod 22 touches the micro switch, allowing the steam generated during the operation of the coffee machine to be released. This design can prevent the release of high-temperature steam when the suspended milk frother is not properly installed, ensuring safe use.

[0046] Secondly, such as Figure 7 As shown, this utility model provides a coffee machine, including a main body 100, and also includes the suspended milk frother mentioned in the first aspect above. The suspended milk frother is detachably suspended on the main body 100 by a suspension device 5.

[0047] In practical application, the main body 100 has a socket that matches the shape of the insert 52, and the socket has a limiting groove that matches the limiting part 521. When the suspended milk frother is installed on the main body 100, the other end of the insert 52 passes through the socket, so that the limiting part 521 is locked in the socket on the main body 100. When it is necessary to remove the suspended milk frother from the main body 100, press the drive member 51 to make the limiting part 521 correspond to the socket, and then pull the suspended milk frother away from the main body 100 to remove it from the main body 100. When it is necessary to install the suspended milk frother on the main body 100 again, simply align the insert 52 with the socket and insert it. During the insertion process, the reset member 51 will be compressed. After the insert 52 is inserted into place, the elastic force of the compressed reset member 51 makes the limiting part 521 lock in the socket of the coffee machine, thus realizing the installation of the suspended milk frother.

[0048] In summary, in one or more embodiments of this utility model, the suspended milk frother and coffee machine of this utility model are detachably installed on the coffee machine by means of a suspension device, which makes installation and disassembly convenient.

[0049] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model.
