[0003] In the related art, a breast pump generally includes a breast shield and a breast pump body (including a housing, a pump, a control panel, a milk bowl, etc.). When a user uses a breast pump, after the breast shield is placed against the breast, the pump generates negative pressure to extract breast milk and then transfer it into the milk bowl for storage. However, in low-temperature environments, the surface temperature of the breast shield decreases due to the influence of the ambient temperature. When the user places the breast shield against the breast, the low temperature often causes a cold and irritating sensation to the user at first. This not only causes an uncomfortable user experience, but also may reduce the breast pumping efficiency due to the user's discomfort.

[0062] The following will clearly and completely describe the concept of the invention and the technical effects produced by it in conjunction with the embodiments, so as to fully understand the purpose, features and effects of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present invention.

[0063] In the description of the embodiments of the present invention, if the word "several" is mentioned, it means more than one; if the word "plurality" is mentioned, it means more than two; if the word "greater than," "less than," or "exceeds," it should be understood as excluding the number itself; if the word "above," "below," or "within" is mentioned, it should be understood as including the number itself. If the word "first" or "second" is mentioned, it should be understood as distinguishing technical features and should not be understood as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0064] Referring to Figure 1 , an embodiment of the present invention provides a method for controlling the preheating of a breast shield, wherein a heating component is embedded in the breast shield, and the preheating of the breast shield is controlled by controlling the heating of the heating component. In the embodiment of the present invention, the preheating control method is typically applied to a controller of a breast pump and includes the following steps:

[0065] S100, collecting current temperature information of the breast shield;

[0066] To provide users with more precise temperature control, improve user comfort, and enhance breast pumping efficiency, the current temperature information monitored and collected should be the current temperature information of the area where the breast shield contacts the user's breast. Because the preheating control method of the present invention is typically used in low-temperature environments, and the heating component embedded in the breast shield may cause inconsistent temperature differences between the side where the breast shield contacts the user's breast (the inside of the breast shield) and the other side, monitoring and collecting the current temperature information of the area where the breast shield contacts the user's breast can provide users with more precise preheating control.

[0067] S200, determining the relationship between the current temperature information and the preset temperature range;

[0068] The preset temperature range is a temperature range that is fixed and suitable for human body temperature after multiple tests, or a larger temperature range is set, and the user can choose to select a preset temperature range within the larger temperature range. In this embodiment, the range of the preset temperature range is usually small or even a specific temperature value, such as any of 38°C, 38.3°C, 38.5°C, 38-38.3°C, 38-38.5°C, or 38-39°C. However, in order to prevent the heating component from switching back and forth between on and off during preheating control, a smaller preset temperature range is usually set. The principle of setting the preset temperature range is that it is higher than the normal human body temperature, does not cause damage to the skin or other tissues or organs of the human body, or does not cause a burning sensation to the user. It should provide the user with a warm and comfortable feeling when the breast shield is attached to the breast.

[0069] If in step S200, it is determined that the current temperature information is lower than the preset temperature range, the following steps are executed:

[0070] S300: Outputting a heating control signal to control the operation of the heating component to heat the breast shield;

[0071] If the current temperature information is lower than a preset temperature range, it indicates that if the user places the breast shield against the breast to express milk, the current temperature of the breast shield is too low to provide the user with a comfortable feeling of warmth. Therefore, after determining that the current temperature information is lower than the preset temperature range, a heating control signal is output to control the operation of the heating component, thereby raising the temperature of the breast shield to provide a comfortable temperature for the user. In some specific embodiments, the component of the breast shield that contacts the user includes a flange made of silicone. By embedding and fixing the heating component in the flange, when the heating component is operating, the flange can effectively conduct heat, thereby ensuring that the temperature of each area where the flange contacts the user's breast is relatively consistent, avoiding large temperature differences between different areas where the flange contacts the user's breast.

[0072] If it is determined in step S200 that the current temperature information is higher than the preset temperature range, the following steps are executed:

[0073] S400, stop outputting the heating control signal to stop the heating component from working;

[0074] If the current temperature exceeds the preset temperature range, the breast shield is too hot. Applying the breast shield to the user's breast could result in burns or a burning sensation during breastfeeding. Therefore, if the current temperature exceeds the preset range, the heating control signal is stopped, deactivating the heating element and allowing the breast shield's temperature to naturally decrease.

[0075] If it is determined in step S200 that the current temperature information is within the preset temperature range, the following steps are executed:

[0076] S500: Output a constant temperature control signal to control the operation of the heating component so that the heating component maintains the current temperature.

[0077] Among them, when the current temperature information is within the preset temperature range, it means that the temperature of the breast shield at this time can provide the user with a warm and comfortable feeling. At the current temperature of the breast shield, when the user fits the breast shield to the breast to express milk, it can bring a warm and comfortable feeling to the user and help improve the efficiency of milk expression.

[0078] An embodiment of the present invention provides a preheating control method for a breast shield. By controlling the working state of a heating component embedded in the breast shield, the temperature of the area where the breast shield contacts the user's breast reaches a preset temperature range. As a result, when the user uses a breast pump to express milk, the area where the breast shield contacts the user's breast will not cause a cold irritation to the user due to the low temperature of the use environment, which would cause a very poor user experience and possibly affect the efficiency of milk extraction.

[0079] 2 , in some embodiments, the working status of the heating component in the breast shield is fed back to the user to prompt the user whether the current temperature information of the breast shield is suitable for use. Specifically, the working status feedback of the heating component can be achieved by controlling the color of the indicator light. For example, if the indicator light is red, it means that the heating component is working in a heating mode, if the indicator light is green, it means that the heating component is working in a constant temperature mode, and if the indicator light is off, it means that the heating component has stopped working. In this embodiment, when the heating component is working and the current temperature information is within the preset temperature range, the indicator light will be green. At this time, the user can attach the breast shield to the breast to perform the milk pumping operation. For the sake of user safety and to effectively save the power consumption of the breast pump, when the user attaches the breast shield to the breast to perform milk pumping, the preheating control method should also include the steps of:

[0080] S600: Determine whether breast shield fitting pressure information is received;

[0081] Among them, the fitting pressure information of the breast shield is usually obtained by embedding a pressure sensor in the flange of the breast shield. When the user fits the breast shield to the breast to perform milk extraction, the flange will produce corresponding deformation, and then the pressure sensor will transmit the collected fitting pressure information to the controller. The controller will adjust and control the working state of the heating component accordingly according to whether the fitting pressure information is received.

[0082] If it is determined in step S600 that the fitting pressure information is received, the following steps are executed:

[0083] S700: Stop outputting the heating control signal or the constant temperature control signal to stop the heating component from working.

[0084] If, in step S600, it is determined that the fitting pressure information has been received, this indicates that the user has placed the breast shield against their breast to begin expressing milk. To ensure user safety and prevent leakage or burns caused by continued operation of the heating element, the controller in the breast pump stops outputting the heating control signal or constant temperature control signal, thereby deactivating the heating element. While the user is placing the breast shield against their breast to begin expressing milk, even if the heating element ceases operation, the contact between the breast shield and the user's body temperature keeps the temperature of the breast shield close to their body temperature for a certain period of time, preventing the user from experiencing a cold sensation that could affect their experience or milking efficiency.

[0085] In other embodiments, when the current temperature information of the breast shield is not within the preset temperature range due to time or other reasons, the user needs to attach the breast shield to the breast to express milk. At this time, if it is desired that the heating component can operate in a faster heating mode so that the current temperature information reaches the preset temperature range more quickly, thereby providing the user with a good user experience, the preheating control method should further include the steps of:

[0086] S900: Determine whether breast shield fitting pressure information is received;

[0087] If it is determined in step S900 that the fitting pressure information is received, the following steps are executed:

[0088] S910, determining whether the current temperature information is lower than a preset temperature range;

[0089] If it is determined in step S910 that the current temperature information is lower than the preset temperature range, the following steps are executed:

[0090] S920: Output a rapid heating control signal to control the heating component to be in a rapid heating working state, so that the current temperature information quickly reaches a preset temperature range.

[0091] In this embodiment, the rapid heating control signal can be achieved by using a PWM signal as the heating control signal, thereby increasing the duty cycle of the PWM signal; or by using multiple heating wires to form a heating component, and then the rapid heating control signal controls all or a preset corresponding number of heating wires to work so that the current temperature information quickly reaches the preset temperature range. These two methods will be specifically explained in subsequent embodiments.

[0092] Referring to FIG3 , in some embodiments, if the temperature of the environment in which the breast pump is used is too low, the surface temperature of the breast shield in contact with the user's breast will also be too low. If the power of the heating control component is too low, the temperature of the breast shield may not be effectively brought to the preset temperature range within the time desired by the user. Alternatively, if the temperature of the environment in which the breast pump is used is relatively high (slightly lower than the preset temperature range), controlling the heating component with a relatively high power will not only make it difficult to monitor the current temperature of the breast shield, but also consume a relatively large amount of power when the heating component is operating at a high power. Therefore, in the above embodiment, outputting a heating control signal to control the operation of the heating component specifically includes the following sub-steps:

[0093] S310, obtaining a temperature difference value based on current temperature information and a preset temperature threshold, where the preset temperature threshold is within a preset temperature range;

[0094] The preset temperature threshold is a set value within a preset temperature range. If the preset temperature range is a certain temperature value, the preset temperature threshold is the preset temperature range. This embodiment obtains the temperature difference between the current temperature information and the preset temperature threshold, and then controls the power of the heating component differently according to the temperature difference.

[0095] S320 , adjusting the heating control signal according to the temperature difference value and controlling the heating component to operate at a desired power.

[0096] After obtaining the temperature difference in step S310, the heating control signal can be adjusted accordingly based on the temperature difference to control the heating component to operate at a desired power. Typically, when the temperature difference is large, the heating control signal is adjusted to control the heating component to operate at a higher power, allowing the breast shield temperature to quickly reach a preset temperature range within the user's desired timeframe. When the temperature difference is small, the heating control signal is adjusted to control the heating component to operate at a lower power, allowing for more accurate control of the breast shield temperature and effectively reducing power consumption in the breast pump.

[0097] 4 , in some embodiments, in order to achieve precise control of the operating power of the heating component, the controller uses a PWM signal as the heating control signal for the heating component. The heating component is controlled by adjusting the duty cycle of the PWM signal, thereby achieving precise control of the operating power of the heating component. Specifically, step S320 in the above embodiment includes the following sub-steps:

[0098] S321, obtaining a preset adjustment power corresponding to the temperature difference;

[0099] Among them, different temperature difference values ​​uniquely correspond to a preset adjustment power. In the specific implementation process, a temperature difference range is usually corresponding to a preset adjustment power, and the corresponding preset adjustment power is continuously adjusted in the process of gradual change of the temperature difference value (the temperature difference value becomes smaller after the current temperature information increases). For example, the temperature difference value of 8℃-10℃ corresponds to the first preset adjustment power (for example, 30W), and the temperature difference value of 6℃-8℃ corresponds to the second preset adjustment power (for example, 20W). Then, after determining the corresponding preset adjustment power through the temperature difference value, precise control of the heating component can be achieved.

[0100] S322: Adjust the duty cycle of the PWM signal according to the preset adjustment power, so that the heating component operates at the desired power.

[0101] Adjusting the duty cycle of the PWM signal can adjust the average voltage of the power supply to the heating component. Each preset regulated power corresponds to a ratio of the PWM signal duty cycle. By adjusting the PWM signal duty cycle, the heating component can be controlled to operate at the desired power. When the preset regulated power value is large, the operating power of the heating component is increased by adjusting the PWM signal duty cycle to a higher value. When the preset regulated power value is small, the power of the heating component is reduced by adjusting the PWM signal duty cycle to a lower value.

[0102] 5 , in some embodiments, if the current temperature information is within a preset temperature range, it is necessary to control the operating power of the heating component to maintain the current temperature. In this embodiment, in order to maintain the current temperature, step S500 in the above embodiment outputs a constant temperature control signal to control the operation of the heating component, including the following sub-steps:

[0103] S510, obtaining a corresponding preset constant power according to current temperature information;

[0104] S520: Adjust the duty cycle of the PWM signal according to the preset constant power so that the heating component maintains the current temperature.

[0105] In this embodiment, if it is necessary to maintain the current temperature of the breast shield, the heating component should be controlled to operate at the corresponding preset constant power, so that the heat generated by the heating component and the heat dissipated are relatively balanced. Then, the duty cycle of the PWM signal can be known according to the voltage value corresponding to the preset constant power. By adjusting the duty cycle of the PWM signal, the average voltage value output by the controller is consistent with the voltage value corresponding to the preset constant power, so that the heat generated by the heating component can maintain the current temperature of the breast shield.

[0106] Referring to Figure 6, in some examples, the heating component includes multiple heating wires, and the multiple heating wires are embedded in the breast shield. Specifically, in actual design applications, the multiple heating wires are embedded in the flange (the flange is a component of the breast shield, and the cavity formed by the flange accommodates the user's breast for breast pumping). The multiple heating wires are evenly distributed around the breast pumping channel in the flange, so that when the multiple heating wires are working, the temperature of each area of ​​the flange that is in contact with the user's breast is relatively consistent. Then, in the above embodiment, step S320 adjusts the heating control signal according to the temperature difference value and controls the heating component to operate at the desired power, which includes the following sub-steps:

[0107] S323, obtaining a corresponding preset number of heating wires according to the temperature difference;

[0108] S324: The heating control signal is used to control a corresponding number of heating wires to operate.

[0109] In this embodiment, when the temperature difference is greater, the corresponding preset number of heating wires increases. This allows more heating wires to operate simultaneously, resulting in a higher operating power (the total amount of heat generated), thereby enabling the breast shield to be heated to the preset temperature range within the user's desired time. Conversely, when the temperature difference is smaller, the corresponding preset number of heating wires decreases. This allows a smaller number of heating wires to operate simultaneously, resulting in a lower operating power, thereby enabling precise control of the temperature of the flange (breast shield) and saving power for the breast pump.

[0110] 6 and 7 , in a specific embodiment, the plurality of heating wires include a first heating wire R1, a second heating wire R2, a third heating wire R3, a fourth heating wire R4, a heating wire R5, and a sixth heating wire R6; wherein the first heating wire R1 to the third heating wire R3 are connected in parallel, and the fourth heating wire R4 to the sixth heating wire R6 are connected in parallel. When the temperature difference value obtained in the above embodiment is large, by simultaneously controlling the operation of the first heating wire R1 to the third heating wire R6, the temperature of the breast shield can be heated to a preset temperature range within the user's desired time. When the temperature difference value in the above embodiment is small, by controlling the operation of the first heating wire R1 to the third heating wire R3 or the fourth heating wire R4 to the sixth heating wire R6, the temperature of the flange (breast shield) can be precisely controlled, while saving power for the breast pump.

[0111] 6 and 8 , in a specific embodiment, the plurality of heating wires include a first heating wire R1, a second heating wire R2, a third heating wire R3, a fourth heating wire R4, a heating wire R5, and a sixth heating wire R6; wherein the first heating wire R1 to the sixth heating wire R6 are connected in parallel. When the temperature difference value obtained in the above embodiment is large, by increasing the duty cycle of the PWM signal and increasing the operating power, the temperature of the breast shield can be heated to a preset temperature range within the user's desired time. When the temperature difference value in the above embodiment is small, by reducing the duty cycle of the PWM signal and reducing the operating power, the temperature of the flange (breast shield) can be precisely controlled while saving power to the breast pump.

[0112] In some other embodiments, the heating assembly includes a spiral heating wire embedded in the flange. In this embodiment, the operating control method of the spiral heating wire is consistent with the operating control method of the above embodiment in which the first heating wire R1 to the sixth heating wire R6 are connected in parallel, and will not be described in detail here.

[0113] In some embodiments, a temperature sensor is embedded in the flange of the breast shield to monitor and collect the current temperature of the breast shield. In this embodiment, the temperature sensor may include one or more temperature sensors. When multiple temperature sensors are provided, they should be evenly spaced relative to the flange. The average value of the temperature information collected by the multiple temperature sensors is used as the current temperature information. When the temperature information collected by any of the temperature sensors exceeds a preset threshold, the controller stops outputting the heating control signal, causing the heating assembly to be deactivated.

[0114] Referring to Figure 9 , one embodiment of the present invention provides a breast shield comprising a heating assembly, a temperature acquisition unit, and a breast shield body. The heating assembly and the temperature acquisition unit are both embedded and fixedly mounted in the breast shield body. The temperature acquisition unit is configured to collect real-time information about the current temperature of the breast shield body and transmit this information to an external controller. The external controller, based on this information, outputs a control signal to control the heating assembly to a heating state, a stopped state, or a constant temperature state. In this embodiment, the external controller is a breast pump controller corresponding to the breast shield. The principles of the process by which the breast pump controller outputs control signals to control the heating assembly to a heating state, a stopped state, or a constant temperature state correspond to the principles of the preheating control methods for breast shields described in the aforementioned embodiments.

[0115] Referring to Figure 9 , in some embodiments, the heating assembly includes multiple curved heating wires. These curved heating wires prevent the breast shield from deforming when placed against the user's breast, potentially leading to wire breakage. The multiple curved heating wires are evenly distributed around the milk extraction channel, ensuring that the temperature of each area where the breast shield contacts the user's breast is relatively consistent when the multiple heating wires are in operation.

[0116] 9 and 8 , in some embodiments, multiple curved heating wires are connected in parallel. In this embodiment, the heating control signal for the multiple curved heating wires is a PWM signal, and the operating power of the multiple curved heating wires is adjusted by adjusting the duty cycle of the PWM signal.

[0117] In other embodiments, the heating component includes a spiral heating wire, which is embedded and fixed in the breast shield body (flange). The heating control signal of the spiral heating wire is a PWM signal, and the working power of the spiral heating wire is adjusted by adjusting the duty cycle of the PWM signal.

[0118] Referring to Figure 10 , in some embodiments, the breast shield is further provided with a pressure collection unit. The pressure collection unit is embedded and fixedly mounted in the breast shield body; typically, it is embedded and fixedly mounted in a flange (the breast shield includes a flange and a milk extraction channel, and the flange is typically made of silicone). When the user fits the flange to the breast to express milk, the flange deforms, and the pressure collection unit acquires pressure data. After transmitting the pressure data to an external controller (breast pump controller), the external controller outputs a control signal to stop the heating component, thereby preventing the user from experiencing electrical leakage or burns caused by the heating component operating while the breast shield is in use.

[0119] In a specific example, the pressure acquisition unit includes a pressure sensor; the pressure sensor transmits the acquired pressure data information to the breast pump controller, so that the breast pump controller controls the working state of the heating component according to the pressure data information.

[0120] The embodiment of the present invention provides a breast shield in which a heating component and a temperature acquisition unit are embedded and fixedly arranged. After the temperature acquisition unit monitors and acquires the current temperature information of the breast shield and transmits it to the breast pump controller, the breast pump controller controls the working state of the heating component according to the current temperature information so that the temperature of the breast shield tends to a preset temperature range and maintains a constant temperature within the preset temperature range. This solves the problem in the related art that when using a breast pump in a scene with a low ambient temperature, the area where the breast shield contacts the user's breast causes a cold stimulation to the user due to the low ambient temperature of the use environment, resulting in a very poor user experience for the user and possibly affecting the milk pumping efficiency.

[0121] 11 , an embodiment of the present invention further provides a breast pump, comprising a breast pump body 100 and a breast shield 200 as described in any of the above embodiments; wherein the breast pump body 100 is provided with a controller 110, and the controller 110 is configured to execute the breast shield preheating control method described in any of the above embodiments to control the working state of the heating component in the breast shield. Furthermore, when a user uses the breast pump to express milk in a low ambient temperature scenario, the controller avoids the user feeling a cold irritation in the area where the breast shield contacts the user's breast due to the low ambient temperature, which would cause a very poor user experience and possibly affect the efficiency of milk extraction.

[0122] 11 , in some embodiments, the breast shield 200 is detachably connected to the breast pump body 100. A first electrical interface 210 is provided on the breast shield 200, and a second electrical interface 120 is provided on the breast pump body 100. The first electrical interface 210 and the second electrical interface 120 are also detachably connected. When the breast shield 200 is connected to the breast pump body 100, the first electrical interface 210 and the second electrical interface 120 are aligned and connected at the same time, so that data transmission communication can be performed to transmit current temperature information and pressure data information on the breast shield 200 side to the controller 210. The controller 210 outputs a control signal based on the received current temperature information and pressure data information to control the working state of the heating component on the breast shield 200 side.

[0123] An embodiment of the present invention further provides a computer-readable storage medium storing an executable program. When the executable program is executed by a processor, the method for controlling the preheating of a breast shield as described in any of the above embodiments is implemented.

Various modifications may be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof may be combined with one another unless there is a conflict.
