[0027] See Figures 1 to 7This embodiment provides a milk frother, including an upper shell 1, a lower shell 2 below the upper shell 1, a heating element 3 below the lower shell 2, the bottom end of the upper shell 1 connected to the top end of the lower shell 2, and the bottom end of the lower shell 2 connected to the top end of the heating element 3; a main board 4 and a motor 5 are provided between the upper shell 1 and the lower shell 2, and the main board 4 is electrically connected to the motor 5 and the heating element 3; a through hole 301 is provided inside the heating element 3, a foaming wheel 6 is provided below the heating element 3, and the motor 5 and the foaming wheel 6 are connected by a rotating shaft 7, which passes through the through hole 301. Function: (1) The lower shell is provided below the upper shell, and a heating element is provided below the lower shell, the bottom end of the upper shell is connected to the top end of the lower shell, and the bottom end of the lower shell is connected to the top end of the heating element; a main board and a motor are provided between the upper shell and the lower shell, and the main board is electrically connected to the motor and the heating element; thus, under the control of the main board, the motor can generate driving force, and the heating element can generate heat to heat the liquid in contact with it. (2) The heating element has an internal through-hole, and a foaming wheel is located below the heating element. The motor and the foaming wheel are connected by a rotating shaft that passes through the through-hole. This allows the motor to drive the foaming wheel to rotate, stirring the liquid in contact with it and frothing the milk. Therefore, this invention integrates the heating element and the foaming wheel into one unit, making it small, portable, and capable of heating liquids, stirring, and frothing milk. It is worth noting that this invention does not require a special, large cup; most cups on the market can be used, making it convenient to use and providing the functions of heating liquids, stirring, and frothing milk.

[0028] Specifically, the mainboard 4 is located above the motor 5, and several buttons 8 are located at the top of the upper shell 1. The buttons 8 are connected and cooperate with the mainboard 4. Function: The buttons 8 facilitate the control of the mainboard 4.

[0029] Specifically, the foaming wheel 6 is cylindrical, and the bottom end of the rotating shaft 7 is connected to the middle of the foaming wheel 6. Function: This allows for better agitation of the liquid in contact with it, thus creating milk foam.

[0030] Specifically, the bottom of the lower shell 2 is provided with an assembly hole 201, and the top of the heating element 3 is provided with an assembly groove 302, with the edge of the assembly hole 201 embedded in the assembly groove 302. Function: This ensures a stable connection between the bottom of the lower shell and the top of the heating element.

[0031] Specifically, the lower shell 2 has a motor sleeve 9 inside, and the motor 5 is assembled inside the motor sleeve 9. The motor shaft of the motor 5 is connected to the top of the rotating shaft 7 through the connector 10. Function: The motor sleeve 9 can fix the motor 5 well. The motor drives the foaming wheel 6 in sequence through the motor shaft, connector, and rotating shaft 7. The foaming wheel rotates to agitate the liquid or froth milk.

[0032] Specifically, the bottom outer wall of the motor sleeve 9 is in close contact with the top of the heating element 3 through the sealing ring 11, and the bottom end of the motor 5 is in close contact with the bottom inner wall of the motor sleeve 9 through the sealing ring 11. The connecting piece 10 passes through the sealing ring 11. Function: The sealing ring 11 provides a better sealing effect, preventing external liquids from entering the machine.

[0033] Specifically, the side wall of the upper shell 1 has an opening 101 for securing the power cord, and the interior of the lower shell 2 has several screw posts 205, which connect to the main board 4, the upper shell 1, or the motor sleeve 9. Function: The screw posts 205 can be connected to screws, thus facilitating the installation and removal of corresponding components.

[0034] Specifically, the lower shell 2 is cylindrical, and a protective mesh 12 is provided below the lower shell 2. The protective mesh 12 is cylindrical and has several mesh holes 1201. The inner circumferential surface of the top of the protective mesh 12 fits over the outer circumferential surface of the bottom of the lower shell 2. The heating element 3 and the bubbling wheel 6 are located inside the protective mesh 12. Function: The mesh holes 1201 can achieve a filtering effect and achieve better liquid stirring.

[0035] Specifically, the lower shell 2 has a first assembly step 202 with its opening facing downwards on the outer circumferential surface at its bottom end. Several positioning posts 206 are provided on the first assembly step 202, and several L-shaped positioning grooves 1202 are provided on the top edge of the protective net 12. The positioning grooves 1202 engage with the positioning posts 206. Function: By rotating the protective net 12, the positioning grooves 1202 and positioning posts 206 can be engaged together, thus facilitating the installation of the protective net 12. Reverse rotation disengages the positioning grooves 1202 from the positioning posts 206, thus facilitating the disassembly of the protective net 12.

[0036] Specifically, the top of the lower shell 2 is provided with an outwardly expanding second mounting step 203, and the top of the second mounting step 203 is provided with an outwardly expanding third mounting step 204. The top of the third mounting step 204 is connected to the bottom of the upper shell 1. Below the lower shell 2 is a shell 13, which is cylindrical. The inner circumferential surface of the top of the shell 13 fits onto the outer circumferential surface of the second mounting step 203, and the protective net 12 is located inside the shell 13. Function: The setting of the second mounting step 203 and the third mounting step 204 provides more space for heating and stirring liquids below, and also facilitates the upward fitting of the shell 13. The shell 13 can be used as a protective shell or as a cup, depending on the actual needs. Of course, this utility model product may not provide a cup (in which case the shell 13 can be used as a protective shell), and the user can use a suitable cup to directly heat liquids, stir, or froth milk with this utility model product.

[0037] Therefore, this utility model integrates the heating element and the stirring head (i.e., the foaming wheel 6) into one piece, making it small in size and easy to carry, while the previous milk frothers were relatively large in size.

[0038] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
