[0016] In this embodiment of the invention, directional indicators (such as up, down, left, right, front, back, etc.) are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indicators will also change accordingly.

[0017] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0018] Please refer to Figure 1 The short-range communication circuit applied to the separate breast milk initiator according to this utility model embodiment includes a data transmission circuit and a data receiving circuit.

[0019] The data transmission circuit is installed on the main unit cup holder of the separate breast milk infuser, and the data receiving circuit is installed on the cup of the separate breast milk infuser.

[0020] The data transmission circuit includes a transmitting coil, a transistor Q1, and a resistor R1. One end of the transmitting coil is connected to the positive terminal of the power supply of the main unit cup holder, and the other end is connected to the drain terminal of the transistor Q1. The gate terminal of the transistor Q1 is connected to the signal transmission terminal (i.e., the TX terminal of the main unit of the milk maker) through the resistor R1, and the source terminal of the transistor Q1 is connected to the negative terminal of the power supply of the main unit cup holder.

[0021] In practice, the transmitting coil is installed at the cup holder. The receiving coil is installed at the bottom of the cup. The structure should ensure that the distance between the two coils does not exceed 30mm when the cup is placed on the main unit's cup holder (for short-distance transmission).

[0022] The data receiving circuit includes a receiving coil, diode D1, transistor Q2, resistors R3, R4, R6, and R7. The two ends of the receiving coil are connected to the positive terminal and GND terminal of diode D1, respectively. The negative terminal of diode D1 is connected to the base of transistor Q2 through resistors R3 and R4 connected in series. The collector of transistor Q2 is connected to the VCC terminal of the cup and the signal receiving terminal (i.e., the RX terminal of the cup) through resistors R6 and R7, respectively. The emitter of transistor Q2 is connected to the GND terminal.

[0023] In one implementation, the data transmission circuit also includes a resistor R2, with its two ends connected to the gate of transistor Q1 and the negative power supply terminal of the host cup holder, respectively.

[0024] In one implementation, the data transmission circuit also includes a capacitor C1, which is connected in parallel with the transmitting coil.

[0025] In one implementation, the data receiving circuit also includes a capacitor C2, one end of which is connected between resistors R3 and R4, and the other end is connected to the GND terminal.

[0026] In one implementation, the data receiving circuit also includes a rectifier diode ZD1 and a resistor R5. The positive and negative terminals of the rectifier diode ZD1 are connected to the GND terminal and the base of the transistor Q2, and the resistor R5 is connected in parallel with the rectifier diode ZD1.

[0027] In one implementation, the data receiving circuit also includes a capacitor C3, with its two ends connected to the signal receiving terminal and the GND terminal, respectively.

[0028] In one implementation, transistor Q1 is an N-channel MOSFET, and transistor Q2 is an NPN transistor.

[0029] The working principle of this invention is as follows: When the main unit outputs a square wave with a frequency of 100kHz and a duty cycle of 10% via R1 to drive Q1, the transmitting coil of the base receives an alternating current, generating a changing magnetic field based on the principle of electromagnetism. At this time, the receiving coil at the bottom of the cup generates an electromotive force due to electromagnetic induction. After rectification by D1 and integration by R3 and C2, a relatively stable DC voltage is obtained. This voltage is then driven by R4 to saturate and pull down Q2, causing RX to change from a high level to a low level signal. That is, when the main unit outputs a square wave of the above specifications, the cup's RX receives a low-level signal; when the main unit outputs a low level, the cup's RX receives a high-level signal. In this way, the main unit can send commands to the cup to achieve communication. After the main unit finishes filling the cup with water, it sends a stirring command to achieve automatic stirring.

[0030] This invention enables the separate-type formula maker to automatically stir the cup after adding water and formula powder, eliminating the need for manual operation and improving the user experience.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
