The milk frother main body 1 is the same as the milk frother on the market, and the low-voltage battery pack 2 is detachably mounted on the milk frother main body 1, thereby providing electric energy for the operation of the milk frother main body 1.

[0027] Specifically, the milk frother main body 1 is provided with a mounting cavity 3, and the mounting cavity 3 is provided with a magnetic suction member. The low-voltage battery pack 2 is provided with a magnetic member, and the low-voltage battery pack 2 is detachably assembled in the mounting cavity 3 through the magnetic attraction of the magnetic member and the magnetic suction member. The magnetic attraction facilitates the disassembly and assembly between the low-voltage battery pack 2 and the milk frother main body 1.

[0028] The magnetic member is a magnet 18, the magnetic suction member is a metal member or a magnet, and the magnetic suction member is preferably an iron member 17. Of course, the magnetic member can also be arranged in the mounting cavity 3, and the magnetic suction member is arranged on the low-voltage battery pack 2. The magnetic member and the magnetic suction member can be visible or invisible, or one of them can be visible and the other can be invisible.

[0029] In the embodiment, the mounting cavity 3 is recessed upward from the lower end of the milk frother main body 1, and the height of the low-voltage battery pack 2 is less than the depth of the mounting cavity 3. At this time, the low-voltage battery pack 2 is assembled at the bottom of the milk frother main body 1. During normal use, the low-voltage battery pack 1 is invisible, and the situation that the low-voltage battery pack 2 is hit or knocked by the objects supported on the plane can be reduced. Of course, the mounting cavity 3 can also be arranged at the side end of the milk frother main body 1, that is, the mounting cavity 3 is recessed inward from the side end surface of the milk frother main body 1.

[0030] In order to better magnetically attract the low-voltage battery pack 2, the number of magnetic parts and magnetic attraction parts is equal, and the magnetic parts are several, and preferably according to the central symmetry of the low-voltage battery pack 2, the distribution is annular.

[0031] In this embodiment, the low-voltage battery pack 2 is provided with an electrically connected control panel and a rechargeable battery, and the outer surface of the low-voltage battery pack 2 is provided with a bidirectional communication socket 4 and a positive socket 5 and a negative socket 6 arranged on both sides of the bidirectional communication socket 4. The bidirectional communication socket 4, the positive socket 5 and the negative socket 6 are electrically connected with the control panel, and the bidirectional communication pin 7 and the positive pin 8 and the negative pin 9 arranged on both sides of the bidirectional communication pin 7 are arranged in the mounting cavity 3.

The electric quantity display button 15 and the electric quantity display lamps 16 are electrically connected with the control board. The charging state or the electric quantity state can be judged by the number of the lighted electric quantity display lamps. For example, when all the electric quantity display lamps 16 are lighted, it means that the rechargeable battery is fully charged. When the electric quantity display lamps are flickering, it means that the rechargeable battery is being charged. When the number of the lighted electric quantity display lamps is gradually reduced, it means that the electric quantity of the rechargeable battery is gradually reduced. The use mode of the electric quantity display lamps can be the same as the prior art, and thus will not be described here.

[0038] When the milk frother needs to be used, the milk frother is turned on. The operation mode is the same as the prior art, and thus will not be described here. When the electric quantity of the low-voltage battery pack 2 is too low, due to the cooperation of the bidirectional communication pin 7 and the bidirectional communication socket 4, a signal will be sent to the circuit board in the milk frother main body 1. The circuit board will send a signal to remind the user to charge the low-voltage battery pack 2. The user only needs to pull the low-voltage battery pack 2 outward to separate the low-voltage battery pack 2 from the milk frother main body 1. Then, the low-voltage battery pack 2 can be charged by being placed in a charging seat or being connected with a charging wire. When the low-voltage battery pack 2 is being charged, the electric quantity of the low-voltage battery pack 2 can be observed in real time through the electric quantity display lamps 16 by pressing the electric quantity display button 15. After the charging of the low-voltage battery pack 2 is completed, the low-voltage battery pack 2 is inserted into the mounting cavity 3. Under the cooperation of the magnetic attraction of the magnetic member and the magnetic piece, the low-voltage battery pack 2 can be conveniently assembled in the mounting cavity 3 to provide operating electric energy for the milk frother main body 1.

[0039] The applicant adopts the low-voltage battery pack 2 with 48-volt or 12-volt direct current voltage, which can realize the normal operation of the milk frother main body 1 and greatly reduce the safety hazards of the milk frother.
