Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Furthermore, the use of terms such as "first" and "second" in this utility model is 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 as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art.

[0042] Existing manual pressing methods for dispensing powder have several significant problems: Users find it difficult to accurately control the amount dispensed each time. This can lead to either too much or too little product being squeezed out, affecting the makeup effect and causing waste, especially for high-end or high-cost cosmetics. Furthermore, users need to press multiple times to obtain the desired amount of foundation, increasing usage time and complexity, and resulting in low powder dispensing efficiency.

[0043] This invention proposes a smart pump head control circuit for foundation liquid.

[0044] Please see Figure 1 In one embodiment of this utility model, the intelligent foundation pump head includes a mechanical component for dispensing foundation powder and a motor MT for driving the mechanical component. The control circuit of the intelligent foundation pump head includes:

[0045] Motor drive circuit 01, which is connected to motor MT;

[0046] Touch input circuit 02 is used to input corresponding control commands when triggered by the user; wherein, the control commands are used to control the amount of foundation powder dispensed.

[0047] The receiving sensing circuit 03 is set close to the receiving area of ​​the foundation liquid. The receiving sensing circuit 03 is used to detect whether there is an object that receives the foundation liquid in the receiving area and outputs a corresponding detection signal.

[0048] The control circuit 04 is connected to the motor drive circuit 01, the touch input circuit 02, and the receiving sensing circuit 03. The control circuit 04 is used to control the operation of the motor drive circuit 01 based on the control command when it is confirmed that an object for receiving foundation liquid is placed in the receiving area according to the detection signal, so as to drive the motor MT to move.

[0049] In one feasible implementation, please refer to Figure 7The control circuit 04 may include a main control chip U1, a push-button switch K, an LED DA, a third capacitor C3, a fourth capacitor C4, and a twelfth resistor R12. The circuit consisting of the third capacitor C3, the fourth capacitor C4, and the twelfth resistor R12 is used to convert the battery voltage into the voltage output required by the main control chip U1. The push-button switch K is used for powering on / off, and the LED DA serves as an indicator light to display information.

[0050] It should be noted that the touch input circuit 02 can be equipped with multiple touch buttons, each with a dispensing volume of 0.5ml, 1ml, 2ml, and a custom dispensing volume. When a user touches a touch button, the main control chip U1 detects which button is selected and dispenses powder according to the preset requirement. If a custom dispensing volume is selected, powder will be dispensed continuously until the touch operation ends. Thus, this embodiment makes powder dispensing volume adjustment more convenient and precise.

[0051] It should be noted that the receiving sensing circuit 03 can perform sensing detection to determine whether a hand or foundation brush is continuously in the receiving area to receive foundation liquid. If not, or if the object is removed midway, an indicator light can provide a corresponding prompt. Otherwise, accidental operation will waste foundation liquid, especially if the user touches the custom setting. Thus, this embodiment can avoid foundation liquid waste caused by accidental operation.

[0052] It should be noted that the powder dispensing process of the foundation liquid can be simulated by a motor MT (Mechanical Manual Transmission). In this embodiment, several key parameters, such as the powder dispensing amount, maximum pressing time, and recovery time, can be preset through the control circuit 04. After the motor MT starts, it performs the pressing action according to the preset maximum pressing time. When the motor MT reaches the maximum pressing time, the automatic control triggers the recovery phase, the motor MT stops pressing, and enters the recovery time phase. After the recovery time ends, the motor MT is ready to perform the next pressing operation. The working status of the motor MT is monitored in real time by the control circuit 04 to ensure that the motor MT does not exceed the preset maximum pressing time during each pressing process, and that the pressing action can be resumed after the recovery time. During this process, the movement of the motor MT can be precisely controlled to ensure a smooth and efficient powder dispensing process. Thus, this embodiment can use a motor MT to replace manual pressing, effectively avoiding the instability of manual operation and ensuring consistency and accuracy of each pressing. Furthermore, the movement of the motor MT can be automatically managed by the control circuit 04, reducing the complexity and inconvenience of user operation.

[0053] In this embodiment, when the user triggers the touch input circuit 02 to input a control command, if the receiving sensing circuit 03 detects that an object for receiving foundation liquid has been placed in the receiving area, it outputs a corresponding detection signal. The control circuit 04 can determine the presence of an object for receiving foundation liquid in the receiving area based on this detection signal, and according to the user's control command, controls the motor drive circuit 01 to work, thereby driving the motor MT to move and accurately control the dispensing of foundation liquid according to the amount of powder dispensed corresponding to the control command. Thus, this embodiment eliminates the need for manual pressing to dispense powder, effectively avoiding the instability of manual operation and solving the problems of inaccurate powder dispensing and low powder dispensing efficiency in existing manual pressing powder dispensing methods.

[0054] In this invention, when a user triggers the touch input circuit 02 to input a control command, if the receiving sensing circuit 03 detects that an object for receiving foundation liquid has been placed in the receiving area, it outputs a corresponding detection signal. The control circuit 04 can determine the presence of an object for receiving foundation liquid in the receiving area based on this detection signal, and according to the user's control command, controls the motor drive circuit 01 to work, thereby driving the motor MT to precisely control the dispensing of foundation liquid according to the amount of powder dispensed corresponding to the control command. Thus, this invention eliminates the need for manual pressing to dispense powder, effectively avoiding the instability of manual operation and solving the problems of inaccurate powder dispensing and low efficiency in existing manual pressing powder dispensing methods.

[0055] Please see Figure 2 and Figure 3 In one embodiment of this utility model, the receiving sensing circuit 03 includes:

[0056] The transmitting circuit is connected to the control circuit 04. The transmitting circuit is used to transmit infrared light signals to the receiving area.

[0057] The receiving circuit is connected to the control circuit 04. The receiving circuit is used to detect whether the infrared light signal reflected back from the surface of the object is received, and outputs the corresponding detection signal.

[0058] It should be noted that when the foundation pump head is in standby or active mode, control circuit 04 controls the transmitting circuit to operate. If an object (such as a makeup brush, sponge, or finger) is placed in the receiving area, the emitted infrared light will illuminate the surface of the object and be reflected back. The receiving circuit continuously monitors whether there is a reflected infrared light signal and outputs a corresponding detection signal. In this way, it ensures that the powder dispensing operation is only performed when a valid object is detected, and it also avoids misoperation caused by unintentional touch or other interference, thus improving the reliability of use.

[0059] Please see Figure 2In one embodiment of this utility model, the transmitting circuit includes a first resistor R1, a second resistor R2, an infrared emitting diode TX, and a first transistor Q1;

[0060] In this circuit, one end of the first resistor R1 is connected to the power supply terminal of the transmitting circuit, the other end of the first resistor R1 is connected to the positive terminal of the infrared emitting diode TX, the negative terminal of the infrared emitting diode TX is connected to the collector of the first transistor Q1, one end of the second resistor R2 is connected to the control circuit O4, the other end of the second resistor R2 is connected to the base of the first transistor Q1, and the emitter of the first transistor Q1 is grounded.

[0061] Please see Figure 3 In one embodiment of this utility model, the receiving circuit includes a third resistor R3, a fourth resistor R4, a fifth resistor R5, a sixth resistor R6, a first capacitor C1, a second transistor Q2, and an infrared receiving tube RX.

[0062] In this circuit, one end of the third resistor R3, one end of the fourth resistor R4, and one end of the fifth resistor R5 are connected to the power supply of the receiving circuit. The other end of the third resistor R3 and one end of the first capacitor C1 are connected to the first end of the infrared receiver RX. The second end of the infrared receiver RX and one end of the sixth resistor R6 are grounded to the emitter of the second transistor Q2. The other end of the fourth resistor R4, the other end of the first capacitor C1, the base of the second transistor Q2, and the other end of the sixth resistor R6 are connected. The other end of the fifth resistor R5 and the collector of the second transistor Q2 are connected to the control circuit O4.

[0063] In this embodiment, both the first transistor Q1 and the second transistor Q2 can be NPN transistors. When the foundation pump head is in standby or active state, a high-level output controls the first transistor Q1 to conduct, allowing current to flow through the infrared emitting diode TX and emitting an infrared light signal of a specific wavelength. If an object receiving foundation is placed in the receiving area, the object's surface reflects the infrared light signal back. The infrared receiving diode RX can receive this infrared light signal and convert it into an electrical signal, generating a corresponding current change. The second transistor Q2 can amplify the weak current generated by the infrared receiving diode RX into a sufficiently strong voltage signal, i.e., the first voltage signal, which is output to the control circuit 04. The control circuit 04 can determine that an object receiving foundation is placed in the receiving area based on this first voltage signal and can then perform the powder dispensing operation. If no object for receiving foundation liquid is placed in the receiving area, the infrared receiver RX will not generate current, and the voltage at the collector of the second transistor Q2 will remain at a high level. At this time, a second voltage signal with a different voltage state than the first voltage signal will be output. The control circuit 04 can determine from this second voltage signal that no object for receiving foundation liquid is placed in the receiving area and will prohibit the powder dispensing operation. Thus, this embodiment can effectively detect whether an object for receiving foundation liquid is placed in the receiving area, and the detection result has high accuracy.

[0064] Please see Figure 4 In one embodiment of this utility model, the control instructions include a first control instruction, a second control instruction, and a third control instruction; the first control instruction, the second control instruction, and the third control instruction are used to control the amount of powder dispensed for different grades of foundation liquid; the touch input circuit 02 includes a touch circuit board, and the multiple output terminals of the touch circuit board are respectively connected to the multiple signal input terminals of the control circuit 04 in a one-to-one correspondence.

[0065] The touch circuit board has a first touch area TK1, a second touch area TK2, and a third touch area TK3. The touch areas of the touch circuit board are used to change the capacitance or resistance value when triggered by the user, generating corresponding control commands. Specifically, when the first touch area TK1 is triggered by the user, the first output terminal of the touch circuit board outputs a first control command to the control circuit 04; when the second touch area TK2 is triggered by the user, the second output terminal of the touch circuit board outputs a second control command to the control circuit 04; and when the third touch area TK3 is triggered by the user, the third output terminal of the touch circuit board outputs a third control command to the control circuit 04.

[0066] Please see Figure 4 In one embodiment of this utility model, the control command further includes a fourth control command; the fourth control command is used to control the continuous powder dispensing time of the foundation liquid; the touch circuit board is also provided with a fourth touch area TK4; when the fourth touch area TK4 is continuously touched by the user, the fourth output terminal of the touch circuit board continuously outputs the fourth control command to the control circuit 04.

[0067] In this embodiment, the touch areas on the touch circuit board detect user touch actions based on changes in capacitance or resistance. When a user's finger touches a certain touch area, the capacitance or resistance value of that area changes. This change is recognized by the internal circuitry of the touch circuit board and converted into a corresponding electrical signal. When the user triggers the first touch area TK1, the second touch area TK2, or the third touch area TK3, the corresponding output terminal outputs a first control command, a second control command, or a third control command to the control circuit 04. Each control command represents a different level of foundation liquid dispensing amount setting, for example, it can be set to 0.5ML, 1ML, and 2ML dispensing amounts sequentially. The fourth touch area TK4 is used to control the continuous dispensing time of the foundation liquid. When the user continuously touches the fourth touch area TK4, the fourth output terminal of the touch circuit board continuously outputs a fourth control command to the control circuit 04. After receiving the fourth control command, if there is an object receiving foundation liquid in the receiving area, the control circuit 04 controls the motor drive circuit 01 to keep the motor MT running, thereby achieving continuous dispensing of foundation liquid until the user stops touching the fourth touch area TK4, at which point the motor MT stops running. This allows for user-defined dispensing amounts. Thus, the dispensing method in this embodiment is relatively flexible and can achieve precise dispensing of preset amounts of foundation liquid.

[0068] Please see Figure 5 In one embodiment of the present invention, the motor drive circuit 01 includes a seventh resistor R7, an eighth resistor R8, a second capacitor C2, a first diode D1 and a first switching transistor Q3.

[0069] Among them, one end of the seventh resistor R7 is connected to the control circuit 04, the other end of the seventh resistor R7 and one end of the eighth resistor R8 are connected to the controlled terminal of the first switch Q3, the other end of the eighth resistor R8 is grounded to the first terminal of the first switch Q3, the second terminal of the first switch Q3, the positive terminal of the first diode D1 and one end of the second capacitor C2 are connected to the first power supply terminal of the motor MT, and the negative terminal of the first diode D1, the other end of the second capacitor C2 and the second power supply terminal of the motor MT are connected to the power supply terminal of the motor drive circuit 01.

[0070] In this embodiment, the first switching transistor Q3 can be a first NMOS transistor. The control circuit 04 can control the gate voltage output to the first NMOS transistor to control its conduction and cutoff, thereby controlling the rotation of the motor MT. The first diode D1 can prevent damage from reverse voltage, and the second capacitor C2 can be used for filtering and voltage regulation to ensure the stable operation of the motor MT.

[0071] In one embodiment of this utility model, the intelligent pump head control circuit for foundation liquid also includes a prompting circuit, which is connected to the control circuit 04;

[0072] The control circuit 04 is also used to control the prompting circuit to issue a prompt message when it is confirmed from the detection signal that no object for receiving foundation liquid is placed in the receiving area.

[0073] Please see Figure 6 In one embodiment of this utility model, the prompting circuit includes a ninth resistor R9, a tenth resistor R10, an eleventh resistor R11, a second switch Q4, and a buzzer BZ.

[0074] Among them, one end of the ninth resistor R9 is connected to the control circuit 04, the other end of the ninth resistor R9 and one end of the tenth resistor R10 are connected to the controlled terminal of the second switch Q4, the other end of the tenth resistor R10 is grounded to the first terminal of the second switch Q4, the second terminal of the second switch Q4 is connected to one end of the eleventh resistor R11, the other end of the eleventh resistor R11 is connected to the first power supply terminal of the buzzer BZ, and the second power supply terminal of the buzzer BZ is connected to the power supply terminal of the prompting circuit.

[0075] In this embodiment, the second switching transistor Q4 can be a second NMOS transistor. The control circuit 04 can control the gate voltage output to the second NMOS transistor to control its conduction and cutoff, thereby controlling the operation / stop of the buzzer BZ. The first diode D1 can prevent damage from reverse voltage, and the second capacitor C2 can be used for filtering and voltage regulation to ensure the stable operation of the motor MT. It is understood that if no object for receiving foundation liquid is placed in the receiving area, the control circuit 04 can control the indicator light to flash and the buzzer BZ to alert the user, preventing accidental powder waste.
