[0002] The breast pump is a tool for expressing milk accumulated in the mammary glands and storing it. It is generally used when the baby cannot directly suck the milk, or when the mother's nipples have problems but still wants to breastfeed.

[0003] In the prior art, the breast pump has significant limitations in actual application, which are as follows:

[0004] Firstly, the flow measured by the existing sensor often has a large deviation from the true value, resulting in flow measurement error.

[0005] Secondly, the sensor currently needs to be set on the inner side of the milk storage container and will be in direct contact with the milk, which may contaminate the milk. In extreme cases, the milk may also seep into the sensor, causing damage to the sensor.

[0006] Thirdly, when using the breast pump, the user needs to constantly try and spend a lot of time to determine the most suitable breast pumping mode for himself.

[0007] To solve any of the above technical problems, the present application is proposed. SUMMARY

[0010] In the above technical solution, the present application eliminates the interference received by the flow detection sensor by setting the flow interference elimination device, which is beneficial to improve the flow detection accuracy.

[0011] In a possible implementation manner of the first aspect, the flow detection sensor comprises a capacitive sensor.

[0012] In a possible implementation manner of the first aspect, the capacitive sensor is a differential capacitive sensor assembly.

[0013] In the implementation manner, the differential capacitive sensor assembly can quantitatively detect the flow, and the detection effect is good.

[0249] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0250] In addition, the terms "first", "second", "third", etc. are used only for descriptive purposes and are not to be construed as indicating or implying relative importance or an ordered ranking of the indicated technical features. Thus, features defined with "first", "second" or "third" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality" is two or more, unless otherwise explicitly and specifically limited.

[0251] As shown in FIG. 1-14, the present application provides a first breast pump, the breast pump 100 comprising a breast shield 111, a milk storage container 110 and a main machine 101. The breast shield 111, the milk storage container 110 and the main machine 101 can be detachably assembled into an integrated structure, or can be a split structure, and the present application does not limit whether it is an integrated structure or a split structure.

[0252] The breast shield 111 is used to cover the human breast and fit the breast. The breast shield comprises a flange 121 in the shape of a horn for fitting the breast, and a breast passage 12a for accommodating the nipple. The breast passage is provided with a milk outlet 12b through which milk can flow into the milk storage container 110.

[0255] The main machine 101 is also provided with a negative pressure mechanism 112, which can directly or indirectly apply negative pressure to the breast shield to suck the breast milk into the milk storage container. Directly applying negative pressure to the breast passage is that the negative pressure mechanism 112 for generating negative pressure directly communicates with the breast passage through an air pipe to generate negative pressure and suck the milk into the milk storage container; indirectly applying negative pressure to the breast passage is that the negative pressure mechanism 112 for generating negative pressure first transmits negative pressure to a deformable gas-liquid separation component, such as a diaphragm 114 or an air bag, and then indirectly applies negative pressure to the breast passage through the vibration or deformation of the diaphragm or air bag to suck the milk into the milk storage container.

[0256] The negative pressure mechanism includes but is not limited to a gas pump, a piezoelectric pump, a diaphragm pump, a hydraulic pump, a mechanical pump and the like, and the present application does not limit it.

[0257] Optionally, the main machine 101 can also include one or more of the following components: an energy supply module, a negative pressure gas circuit, a control circuit board, a solenoid valve and the like.

[0258] In the present application, in order to make the milk collected from the breast shield flow into the milk storage container, the breast pump of the present application further comprises a milk flow path 11a, which comprises at least a part of the milk flow path from the breast passage to the milk storage container.

[0259] The breast pump also comprises a flow detector 113 for detecting the flow of milk through the milk flow path in a non-contact manner.

[0260] Optionally, the flow detector in the embodiment can comprise at least one of a capacitive sensor, an acoustic sensor, an ultrasonic sensor, a laser sensor, and an optical sensor. Among them, the milk flow path or the milk storage container or the milk passage is at least transparent to the position of the optical sensor or the laser sensor, so that the detection light emitted by the optical sensor or the laser sensor can pass through; further, the optical sensor comprises an illumination sensor or an infrared sensor.

[0261] According to the above scheme, the acoustic sensor usually uses the propagation characteristics of sound or vibration to detect the flow of milk in the milk flow path, which can listen to the sound or vibration generated when the milk passes through the pipeline, and infer the milk flow in the milk flow path according to the change of the sound characteristics, when the milk passes through the milk flow path, the noise spectrum generated by the milk flow can be analyzed by the sound or vibration generated by the milk passing through the acoustic sensor, so as to further obtain the milk flow. Because the acoustic sensor is easily affected by external noise, such as environmental noise or other mechanical vibration, therefore, in the actual installation process, a plurality of groups can be arranged around the whole circumference of the milk flow path, and the parameters obtained by the plurality of acoustic sensors are integrated to obtain more accurate milk flow.

[0262] Next, according to a specific embodiment, the first breast pump of the present application will be described in detail.

[0263] Embodiment one:

[0264] Please refer to FIG. 1-2, it is the first embodiment provided by the present application, the breast pump 100 comprises: a milk storage container 110, a breast shield 111, a host 101, a milk flow path 11a and a flow detector 113; wherein the milk storage container is used for storing the milk sucked from the human breast; the breast shield 111 comprises a flange 121 matched with the breast and a breast passage 12a accommodating the nipple, the breast passage is provided with a milk outlet 12b, and the milk can flow into the milk storage container through the milk outlet.

[0265] The host 101 comprises a host shell 117, and a negative pressure system 112 is arranged in the host shell. The negative pressure system directly or indirectly applies negative pressure to the breast passage to suck out the milk and discharge it into the milk storage container. The milk flow path at least comprises a part of the milk flow path from the breast passage to the milk storage container.

[0266] Optionally, in the first embodiment, the milk storage container, the host and the breast shield of the breast pump are an integrated detachable assembly structure.

[0267] According to the above scheme, it can be understood that the milk flow path 11a at least includes a part of the milk flow path in which the milk in the breast milk channel flows into the milk storage container. In some embodiments, the milk flow path 11a includes all the milk flow paths required for the milk in the breast milk channel to flow into the milk storage container, for example, after the milk is sucked from the human breast, it needs to pass through the breast milk channel 12a, and / or the one-way valve 115, and / or the negative pressure chamber 116, and / or the milk inlet 12c of the milk storage container (the position of the milk inlet 12c can be referred to FIG. 6), and the above-mentioned components are all included in the milk flow path. In other embodiments, the milk flow path includes part of the milk flow path required for the milk in the breast milk channel to flow into the milk storage container, for example, after the milk is sucked from the human breast, it passes through the breast milk channel 12a and the one-way valve 115 to flow into the milk storage container, and the above-mentioned milk flow path includes the breast milk channel or the one-way valve 115.

[0268] According to the above scheme, it can be understood that the breast pump further includes a one-way valve 115 connected to the breast milk channel, and the milk flows into the milk storage container through the one-way valve. The outer wall of the one-way valve contacts the inner wall of the milk storage container.

[0269] It can be understood that in the first embodiment, the milk flow path passes through the one-way valve 115, and the one-way valve 115 is part of the milk flow path. The flow detector 113 is used to detect the flow of milk through the milk flow path in a non-contact manner. In the first embodiment, the flow detector is used to detect the flow of milk through the one-way valve 115 in a non-contact manner.

[0270] In this application, the host shell 117 includes an inner wall 141 and an outer wall 142. The inner wall 141 forms an inner cavity for accommodating internal electronic components, such as a negative pressure system or other electronic components. The outer wall 142 of the host shell 117 faces the milk storage container 110.

[0271] In the first embodiment, the flow detector 113 is mounted on the inner wall 141 of the host shell and is aligned with the position of the one-way valve 115. It can be understood that the flow detector is mounted on the inner wall 141 of the host shell and is aligned with the position of the one-way valve 115. When the milk flows from the one-way valve 115, the flow detector can detect the flow of milk through the one-way valve, i.e. the flow detector 113 detects the flow of milk through the one-way valve 115 in a non-contact manner, ensuring the safety and hygiene of the milk. When the breast pump is not needed, the milk storage container and the breast shield are removed from the host shell, so that the flow detector is separated from the milk storage container and the breast shield, thereby allowing the milk storage container and the breast shield to be cleaned, milked, sterilized, and the like. The flow detector does not affect any of the above operations, thereby achieving complete non-contact between the flow detector and the milk.

[0272] In the present embodiment, preferably, the flow detector 113 is aligned with the one-way valve 115 away from the narrow end 13a of the breast pumping passage, the narrow end 13a being the end of the one-way valve 115 away from the breast pumping passage 12a, the milk flow through the narrow end is more concentrated, stable and uniform, and the measured data is better. At the same time, because the milk needs to be rectified to a certain extent when passing through the one-way valve, the narrow end 13a reduces the turbulence phenomenon, so that the flow detector can obtain more accurate data; in addition, because the narrow end 13a is relatively far away from the direct pumping point, the pressure fluctuation is small, which helps to provide a more stable measurement environment.

[0273] In the first embodiment, the flow detector 113 can be set as a capacitive sensor, or an ultrasonic sensor, or an acoustic sensor, or an optical sensor, or a laser sensor, which can detect the flow of milk through the one-way valve 115.

[0274] Embodiment two:

[0275] As shown in FIGS. 3-4, in the second embodiment, the flow detector can be installed on the outer side wall 142 of the main machine housing at least in the position of the one-way valve.

[0276] In the second embodiment, the outer side wall of the one-way valve 115 contacts the inner side wall 144 of the milk storage container, and the outer side wall 142 of the main machine housing 117 contacts the outer side wall 143 of the milk storage container at least in the position of the one-way valve 115; preferably, the outer side wall of the one-way valve is in close contact with the inner side wall of the milk storage container, and the position where the inner side wall 144 of the milk storage container contacts the outer side wall of the one-way valve 115 is inclined, the inclination direction is inclined towards the inside of the milk storage container, which improves the continuity and stability of the liquid flow, reduces the turbulence phenomenon when the milk flows, and provides a more stable measurement environment for the flow detector, thereby obtaining more reliable flow data, and the outer side wall of the main machine housing is in close contact with the milk storage container at least in the position of the one-way valve.

[0277] In the second embodiment, the flow detector is a capacitive sensor 131. The capacitive sensor 131 is a differential capacitive sensor assembly, which includes a double electrode capacitor and a control circuit. The double electrode capacitor includes a first electrode 151 and a second electrode 152 arranged oppositely. The control circuit is configured to charge the double electrode capacitor and detect the capacitance value of the double electrode capacitor. It can be understood that the first electrode 151 and the second electrode 152 are arranged oppositely on the two sides of the outer side wall 142 of the main body shell, so that a capacitor is formed between the first electrode 151 and the second electrode 152. The control circuit measures the charge and discharge characteristics of the capacitor to detect the change of the capacitance value. When there is no milk flowing through, the medium between the first electrode and the second electrode is usually air or other fixed materials. At this time, the capacitor has an initial capacitance value C0. When the milk starts to flow through the area between the first electrode and the second electrode, the milk will enter between the two electrodes, replacing the original medium. Since the milk has a certain dielectric constant (ε), it will affect the capacitance value of the capacitor. The milk as a new medium changes the effective dielectric constant of the capacitor, thereby changing the capacitance value.

[0278] It can be understood that the control circuit will periodically charge and discharge the capacitor formed by the first electrode 151 and the second electrode 152. With the change of the milk flow, the volume of the medium in the capacitor changes, causing the capacitance value to change accordingly. By continuously monitoring the change of the capacitance value, the milk flow can be measured.

[0279] As shown in FIG. 4, in the second embodiment, the capacitive sensor includes a first capacitive sensor 15a for detecting the milk flow and a second capacitive sensor 15b for detecting the interference value. It can be understood that the second capacitive sensor in the embodiment is used to detect the interference value of the milk stored in the milk storage container to the milk on the milk flow path that needs to be detected. By comparing the capacitance value changes of the two capacitors, a differential signal can be obtained, which reflects the change of the measured physical quantity. This can effectively eliminate some common-mode interference, so that the milk stored in the milk storage container will not affect the measurement of the milk on the milk flow path by the first capacitive sensor, thereby improving the accuracy of the milk flow measurement.

[0280] In other cases of the embodiment, the flow detector can also extend from the inner side wall to the outer side wall of the main body shell, which is conducive to the electrical connection of the capacitive sensor.

[0281] Embodiment three:

[0282] As shown in Fig. 5, in the third embodiment, the flow detector is mounted on the outer side wall 143 of the milk storage container at a position at least aligned with the one-way valve 115, i.e. the flow detector detects the flow of milk through the one-way valve 115 in a non-contact manner with the milk, ensuring the safety and hygiene of the milk. The flow detector 113 is also detachably mounted on the outer side wall of the milk storage container. When the breast pump is not needed, the milk storage container is detached from the main housing, and the flow detector is detached from the milk storage container, so that the milk storage container can be cleaned, milked, disinfected, etc., so that the flow detector and the milk are completely non-contact and non-polluted, and the breast pump is easy to clean.

[0283] In the third embodiment, the flow detector is an ultrasonic sensor. The ultrasonic sensor includes a transmitting end 132a for transmitting signals and a receiving end 132b for receiving signals. The transmitting end of the ultrasonic sensor is a piezoelectric ultrasonic sensor assembly, which includes a piezoelectric ceramic substrate that vibrates to generate ultrasonic waves and electrodes that apply current to the piezoelectric ceramic substrate to make it vibrate; the receiving end is used to receive the ultrasonic waves reflected by the transmitting end and returned by the barrier, so as to convert the ultrasonic waves into electrical signals. In this application, the ultrasonic sensor is not limited to the structure described above.

[0284] The ultrasonic sensor measures the flow rate by using the change of the frequency of the ultrasonic waves. When the ultrasonic waves encounter the flowing particles, the frequency of the reflected waves changes due to the Doppler effect, which can detect the flow of milk according to the flowing particles fed back to the ultrasonic sensor when the milk flows through the milk flow path. When the milk passes through the milk flow path, the ultrasonic waves emitted by the ultrasonic sensor contact the milk and feed back different frequencies, so that the flow of the milk can be obtained more accurately.

[0286] As shown in Figs. 6-8, in the fourth embodiment, the milk storage container 110 of the breast pump is detachably assembled below the main machine 101, and the breast cup is detachably assembled on the milk storage container 110.

At least a portion of the outer wall 11b of the milk flow path 11a is exposed outside the milk storage container 110. It can be understood that the portion of the outer wall of the milk flow path exposed outside the milk storage container in the present embodiment does not contact the milk. The flow detector 113 is arranged on or near the portion of the outer wall 11b of the milk flow path exposed outside the milk storage container, so that the flow detector 113 detects the flow of milk through the milk flow path 11a in a non-contact manner with the milk, ensuring the safety and hygiene of the milk.

[0287] Please refer to FIG. 8 and FIG. 9, in different embodiments, the flow detector 113 is distributed on the whole or part of the outer wall 11b of the milk flow path 11a, which can be set according to the structure of different types of breast pumps to maximize the detection accuracy of the flow detector on different signal breast pumps.

[0325] According to the above scheme, the ultrasonic sensor generally uses the propagation characteristics of sound to detect the flow of milk in the milk flow path, and infers the milk flow in the milk flow path according to the change of the sound characteristics. When the milk passes through the milk flow path, the noise spectrum generated by the flow of the milk can be analyzed by the sound generated by the milk passing through the ultrasonic sensor, so as to further obtain the milk flow. Since the ultrasonic sensor is easily affected by external noise, such as environmental noise or other mechanical vibrations, multiple groups of ultrasonic sensors can be installed around the entire circumference of the milk flow path during actual installation, and the parameters obtained by the multiple groups of ultrasonic sensors are integrated to obtain a more accurate milk flow.

[0336] In the present embodiment, preferably, the ultrasonic sensor 118 is aligned with the narrow end 13a of the one-way valve 115 away from the breast passage 12a, the narrow end 13a being the end of the one-way valve 115 away from the breast passage 12a, the milk flowing through the narrow end is more concentrated, stable and uniform, and the measured data is better. At the same time, because the milk needs to be rectified to a certain extent when passing through the one-way valve, the narrow end 13a reduces the turbulence phenomenon, so that the ultrasonic sensor can obtain more accurate data; in addition, since the narrow end 13a is relatively far away from the direct suction point, the pressure fluctuation is small, which helps to provide a more stable measurement environment.

[0337] Embodiment two:

[0338] As shown in FIG. 18, in the second embodiment, the ultrasonic sensor 118 can be mounted on the outer side wall 142 of the main housing and aligned with the position of the one-way valve.

[0339] In the second embodiment, the outer wall of the one-way valve 115 contacts the inner wall 144 of the milk storage container, and the outer wall 142 of the main machine housing contacts the outer wall 143 of the milk storage container at least at the position corresponding to the one-way valve 115. Preferably, the outer wall of the one-way valve closely contacts the inner wall of the milk storage container, and the position where the inner wall 144 of the milk storage container contacts the outer wall of the one-way valve 115 is inclined towards the inside of the milk storage container. The inclined design improves the continuity and stability of the liquid flow, reduces the turbulence of the milk liquid, and provides a more stable measurement environment for the ultrasonic sensor, thereby obtaining more reliable flow data. The outer wall of the main machine housing closely contacts the milk storage container at least at the position corresponding to the one-way valve.

[0340] Embodiment three:

[0341] As shown in FIG. 19, in the third embodiment, the ultrasonic sensor is mounted on the outer wall 143 of the milk storage container at least at the position corresponding to the one-way valve 115, i.e., the ultrasonic sensor detects the flow of milk through the one-way valve 115 in a non-contact manner with the milk, ensuring the safety and hygiene of the milk. The ultrasonic sensor 118 is also detachably mounted on the outer wall of the milk storage container. When the breast pump is not needed, the milk storage container is detached from the main machine housing, and the ultrasonic sensor is detached from the milk storage container, so that the milk storage container can be cleaned, milked, disinfected, etc., thereby realizing complete non-contact between the ultrasonic sensor and the milk without pollution, and further ensuring the convenience of cleaning the breast pump.

[0342] In the third embodiment, the ultrasonic sensor includes a transmitting end 118a for transmitting signals and a receiving end 118b for receiving signals. The transmitting end of the ultrasonic sensor is a piezoelectric ultrasonic sensor component, which includes a piezoelectric ceramic substrate that vibrates to generate ultrasonic waves and electrodes that apply current to the piezoelectric ceramic substrate to make it vibrate; the receiving end is used to receive the ultrasonic waves reflected by the transmitting end and returned by encountering an obstacle, so as to convert the ultrasonic waves into electrical signals. In this application, the ultrasonic sensor is not limited to the structure described above.

[0343] The ultrasonic sensor measures the flow rate by using the change of the frequency of the ultrasonic waves. When the ultrasonic waves encounter the flowing particles, the reflected frequency changes due to the Doppler effect, which can detect the flow of milk according to the flowing particles fed back to the ultrasonic sensor when the milk flows through the milk flow path. When the milk passes through the milk flow path, the ultrasonic waves emitted by the ultrasonic sensor contact the milk and feed back different frequencies, so that more accurate flow rate of the milk can be obtained.

[0359] Embodiment eight:

[0360] As shown in FIG. 28, the main machine 101 of the breast pump is detachably assembled with the milk storage container 110 and the breast shield 111, and the negative pressure system 112 is arranged in the main machine shell 117.

[0362] As shown in FIGS. 1 and 29-41, the present application further provides a third breast pump.

[0370] The breast pump of the present application further includes a capacitive sensor 119 for detecting the flow rate of the milk passing through the milk flow path in a non-contact manner.

[0371] The third breast pump of the present application will be described in detail below according to a specific embodiment.

[0372] Embodiment I:

[0373] Please refer to FIG. 1 and FIG. 29, the first embodiment provided by the present application, the breast pump 100 includes: a milk storage container 110, a breast shield 111, a host 101, a milk flow path 11a, and a capacitive sensor 119; wherein the milk storage container is used to store the milk extracted from the human breast; the breast shield 111 includes a flange 121 that fits the breast and a milk extraction channel 12a that contains the nipple, the milk extraction channel is provided with a milk outlet 12b, and the milk can flow into the milk storage container through the milk outlet.

[0374] The host 101 includes a host shell 117, and the host shell is provided with a negative pressure system 112 that directly or indirectly applies negative pressure to the milk extraction channel to extract the milk and discharge it into the milk storage container; the milk flow path at least includes a portion of the milk flow path from the milk extraction channel to the milk storage container.

[0375] Optionally, in this embodiment I, the milk storage container, the host, and the breast shield of the breast pump are an integrated detachable assembly structure.

[0376] According to the above scheme, it can be understood that the milk flow path 11a at least includes a part of the milk flow path in which the milk in the breast milk channel flows into the milk storage container. In some embodiments, the milk flow path 11a includes all the milk flow paths required for the milk in the breast milk channel to flow into the milk storage container, for example, after the milk is sucked from the human breast, it needs to pass through the breast milk channel 12a, and / or the one-way valve 115, and / or the negative pressure chamber 116, and / or the milk inlet 12c of the milk storage container, and the above-mentioned components are all included in the milk flow path. In other embodiments, the milk flow path includes part of the milk flow path required for the milk in the breast milk channel to flow into the milk storage container, for example, after the milk is sucked from the human breast, it passes through the breast milk channel 12a and the one-way valve 115 to flow into the milk storage container, and the above-mentioned milk flow path includes the breast milk channel or the one-way valve 115.

[0377] According to the above scheme, it can be understood that the breast pump further includes a one-way valve 115 connected to the breast milk channel, and the milk flows into the milk storage container through the one-way valve. The outer wall of the one-way valve contacts the inner wall of the milk storage container.

[0378] It can be understood that in Embodiment One, the milk flow path passes through the one-way valve, and the one-way valve 115 is part of the milk flow path. The capacitive sensor 119 is used to detect the flow of milk through the milk flow path in a non-contact manner. In Embodiment One, the capacitive sensor is used to detect the flow of milk through the one-way valve 115 in a non-contact manner.

[0379] In this application, the main machine shell 117 includes an inner wall 141 and an outer wall 142. The inner wall 141 forms an inner cavity for accommodating internal electronic components, such as a negative pressure system or other electronic components. The outer wall 142 of the main machine shell 117 faces the milk storage container 110.

[0380] In Embodiment One, the capacitive sensor 119 is mounted on the inner wall 141 of the main machine shell and is aligned with the position of the one-way valve 115. It can be understood that the capacitive sensor is mounted on the inner wall 141 of the main machine shell and is aligned with the position of the one-way valve 115. When the milk flows from the one-way valve 115, the capacitive sensor can detect the flow of milk through the one-way valve, i.e. the capacitive sensor 119 detects the flow of milk through the one-way valve 115 in a non-contact manner, ensuring the safety and hygiene of the milk. When the breast pump is not needed, the milk storage container and the breast shield are removed from the main machine shell, so that the capacitive sensor is separated from the milk storage container and the breast shield, thereby allowing the milk storage container and the breast shield to be cleaned, emptied, and sterilized, and the capacitive sensor does not affect any of the above operations, thereby achieving complete non-contact between the capacitive sensor and the milk.

[0381] In this embodiment, preferably, the capacitive sensor 119 is aligned with the one-way valve 115 away from the narrow end 13a of the breast pumping passage 12a, the narrow end 13a being the end of the one-way valve 115 away from the breast pumping passage 12a, the milk flowing through the narrow end is more concentrated, stable and uniform, and the measured data is better. At the same time, because the milk needs to be rectified to a certain extent when passing through the one-way valve, the narrow end 13a reduces the turbulence phenomenon, so that the capacitive sensor can obtain more accurate data; in addition, because the narrow end 13a is relatively far away from the direct pumping point, the pressure fluctuation is small, which helps to provide a more stable measurement environment.

[0382] Embodiment two:

[0383] As shown in FIGS. 3-31, in this embodiment two, the capacitive sensor 119 can be mounted on the outer side wall 142 of the main machine housing at least in the position of the one-way valve.

[0384] In this embodiment two, the outer side wall of the one-way valve 115 contacts the inner side wall 144 of the milk storage container, and the outer side wall 142 of the main machine housing contacts the outer side wall 143 of the milk storage container at least in the position of the one-way valve 115; preferably, the outer side wall of the one-way valve closely contacts the inner side wall of the milk storage container, and the position where the inner side wall 144 of the milk storage container contacts the outer side wall of the one-way valve 115 is inclined, the inclination direction being towards the inside of the milk storage container. By the inclined design, the continuity and stability of the liquid flow are improved, so that the milk flow rate is reduced when passing through, the turbulence phenomenon is reduced, a more stable measurement environment is provided for the capacitive sensor, and more reliable flow data is obtained. The outer side wall of the main machine housing closely contacts the milk storage container at least in the position of the one-way valve.

[0385] In this embodiment two, the capacitive sensor 119 is a differential capacitive sensor assembly, which includes a double-electrode capacitor and a control circuit; the double-electrode capacitor includes a first electrode 1191 and a second electrode 1192 arranged oppositely; the control circuit is used for charging the double-electrode capacitor and detecting the capacitance value of the double-electrode capacitor; it can be understood that the first electrode 1191 and the second electrode 1192 are arranged oppositely on the two sides of the outer side wall 142 of the main machine housing, so that a capacitor is formed between the first electrode 1191 and the second electrode 1192, and the change of the capacitance value is detected by measuring the charge and discharge characteristics of the capacitor through the control circuit. When there is no milk passing through, the medium between the first electrode and the second electrode is usually air or other fixed materials, at this time the capacitor has an initial capacitance value C0. When the milk starts to flow through the area between the first electrode and the second electrode, the milk will enter between the two electrodes, replacing the original medium. Because the milk has a certain dielectric constant (ε), it will affect the capacitance value of the capacitor, and the milk as a new medium changes the effective dielectric constant of the capacitor, thereby changing the capacitance value.

[0386] It can be understood that the control circuit will periodically charge and discharge the capacitor formed by the first electrode 1191 and the second electrode 1192, and as the milk flow changes, the medium volume in the capacitor changes, causing the capacitance value to change accordingly. By continuously monitoring the change of the capacitance value, the milk flow can be measured.

[0387] As shown in FIG. 31, in the second embodiment, the capacitive sensor includes a first capacitive sensor 119a for detecting milk flow and a second capacitive sensor 119b for detecting interference value. It can be understood that the second capacitive sensor in this embodiment is used to detect the interference value of the milk stored in the milk storage container to the milk on the milk flow path that needs to be detected. By comparing the capacitance value changes of the two capacitors, a differential signal can be obtained, which reflects the change of the measured physical quantity, and can effectively eliminate some common-mode interference, so that the milk stored in the milk storage container will not affect the measurement of the milk on the milk flow path by the first capacitive sensor, and the accuracy of the milk flow measurement is improved.

[0388] In other cases of the present embodiment, the capacitive sensor can also be arranged from the inner side wall to the outer side wall of the main machine shell, which is conducive to the electrical connection of the capacitive sensor.

[0389] Embodiment three:

[0390] As shown in FIG. 32, in the third embodiment, the capacitive sensor with the oppositely arranged first electrode 1191 and second electrode 1192 is mounted on the outer side wall 143 of the milk storage container at least in alignment with the one-way valve 115, that is, the capacitive sensor detects the milk flow through the one-way valve 115 in a non-contact manner with the milk, ensuring the safety and hygiene of the milk. The capacitive sensor is also detachably mounted on the outer side wall of the milk storage container. When the breast pump is not needed, the milk storage container can be removed from the main machine shell, so that the milk storage container can be cleaned, milked, disinfected and other operations, so that the capacitive sensor and the milk are completely non-contact and non-polluted, and the breast pump is easy to clean.

[0398] In this embodiment five, the capacitive sensor 119 is installed on or close to the outer side wall of the flow detection section 161. The outer side wall of the flow detection section 161 does not contact the milk liquid, so that the capacitive sensor 119 detects the flow of the milk liquid through the milk flow path 11a in a non-contact manner with the milk liquid, ensuring the safety and hygiene of the milk liquid.

[0408] The present application also provides a fourth breast pump. FIG. 42 is a perspective view of the fourth breast pump according to an embodiment of the present application, and FIG. 43 is a sectional view of the fourth breast pump according to an embodiment of the present application.

[0409] As shown in FIG. 43, the breast pump 100 includes the breast shield 111, the milk storage container 110, and the main machine 110.

[0410] The breast shield 111 is used to cover the human breast and fit the breast. The breast shield 111 generally includes a flange in the shape of a horn for fitting the breast and a breast passage for containing. In some cases, the breast passage can also be arranged in the milk storage container 110.

[0411] The milk storage container 110 is used to receive and store the breast milk collected by the breast shield 111, and the milk storage container 110 is in communication with the breast shield 111.

[0412] Optionally, the milk storage container 110 includes a milk cover, a milk bowl, a milk bottle, etc., which are not limited in the present application.

[0413] The main machine 110 is also provided with a negative pressure mechanism, which can directly or indirectly apply negative pressure to the breast shield 111 to suck the breast milk into the milk storage container 110.

[0414] The negative pressure mechanism includes but is not limited to a piezoelectric pump, a diaphragm pump, a hydraulic pump, a mechanical pump, etc.

[0415] Optionally, the main machine 110 can also include one or more of the following components: a power supply module, a negative pressure gas circuit, a control circuit board, an electromagnetic valve, etc.

[0416] Specifically, the power supply module can be a storage battery, a dry battery, or can be directly connected to an external power supply through a power line.

[0417] In FIG. 43, the milk flow path is shown by a dashed line, and the flow direction in the milk flow path is indicated by an arrow. After the milk flows out of the breast, it flows into the milk storage container 110 along the flow direction.

[0418] The flow detection sensor comprises one of a capacitive sensor, an ultrasonic sensor, an acoustic sensor, and an optical sensor. Preferably, when the flow detection sensor is a capacitive sensor, the capacitive sensor is specifically a differential capacitive sensor assembly.

[0419] The differential capacitive sensor assembly is described below. First, the basic principle of a parallel-plate capacitor is described, which is the basis for constructing a capacitive sensor. Please refer to FIG. 44, which is a schematic diagram of a parallel-plate capacitor according to an embodiment of the present application.

[0420] As shown in FIG. 44, the first electrode and the second electrode are mutually parallel metal conductors, also known as plates or metal electrodes. There is a uniform electric field distribution between the two electrodes. Due to the edge effect, the electric field lines at the edge of the capacitor are curved and divergent.

[0421] The formula for calculating the capacitance of a parallel-plate capacitor is as follows:

[0422] wherein ε r is the dielectric constant of the material between the plates, S is the facing area of the two electrodes of the capacitor, ε0 is the dielectric constant of free space (8.85 x 10 -12 F / m), and d is the distance between the two electrodes of the capacitor.

[0423] In FIG. 44, S is equal to W multiplied by L.

[0424] FIGS. 45-46 are a schematic diagram of the basic principle of differential capacitive detection according to an embodiment of the present application. In this embodiment, a differential capacitive sensor assembly is used as a sensor for detecting the state parameters (including the flow and the interference milk flow detection value) of the milk storage container in the breast pump. The differential capacitive sensor assembly comprises a detection electrode assembly, which comprises a capacitor formed by two mutually parallel and oppositely arranged electrodes. The differential capacitive sensor assembly is used to detect the mutual capacitance between the two electrodes of the capacitor. Instead of a high-low level signal, the output result is a capacitance change value between the two electrodes or a digital signal converted from the capacitance change value.

[0425] For ease of description, the capacitor formed by the two mutually parallel and oppositely arranged electrodes in the differential capacitive sensor assembly is referred to as a parallel capacitor group. In one possible embodiment, the parallel capacitor group is a standard parallel-plate capacitor as shown in FIG. 46. The parallel capacitor group in FIG. 46 comprises a first electrode 1000 and a second electrode 2000. The facing planes of the two electrodes are completely aligned. In another possible embodiment, the facing planes of the two electrodes of the parallel capacitor group are only partially aligned. The first electrode and the second electrode are misaligned in some regions.

[0426] And, the differential capacitor sensor assembly in the present application comprises a control circuit connected to the parallel capacitor group, see Fig. 45. The control circuit is used to charge the parallel capacitor group and collect the electric charge on the parallel capacitor group after a preset time. The capacitance value of the parallel capacitor group is determined according to the electric charge change speed and / or the electric charge change amount.

[0427] The control circuit comprises a conversion unit, which comprises an excitation module, a sampling module and a conversion module. The excitation module generates a charging signal for charging the differential capacitor sensor assembly. The electric charge on the differential capacitor sensor assembly is transmitted to the conversion module through the sampling module. The conversion module converts the analog voltage into a digital signal. The conversion module is connected to a processing unit. The processing unit is used to calculate the state parameter of the milk storage container corresponding to the differential capacitor sensor assembly according to the digital signal.

[0428] Optionally, the conversion unit is a capacitance-to-digital converter. Optionally, the conversion module is an analog-to-digital converter (ADC).

[0429] The conversion unit will be further described below. Please continue to refer to Fig. 45, which is a detection principle diagram of the differential capacitor sensor assembly provided by the present application. As shown in Fig. 45, the detection electrode assembly is connected to the conversion unit. In Fig. 45, the sampling module in the control circuit comprises a switched capacitor circuit and a sample-and-hold circuit.

[0430] The excitation module is used to generate an excitation signal, which is used to charge the parallel capacitor group in the detection electrode assembly. In some cases, the excitation signal is generated by an oscillator in the excitation module. In other cases, the excitation signal is generated by a clock signal received by the excitation module. The present application does not make any limitation.

[0431] The switched capacitor circuit is used to close the switch at the appropriate time to transfer the electric charge on the parallel capacitor group to the input end of the ADC.

[0432] The sample-and-hold circuit is used to keep the voltage on the parallel capacitor group stable before the conversion module converts the voltage. This ensures that the analog-to-digital converter reads a stable voltage value during the conversion process.

[0433] The conversion module is used to convert the analog voltage into a digital signal and input the digital signal to the processing unit (not shown in Fig. 45). In some cases, the conversion module also performs digital filtering during the conversion process to improve the conversion accuracy.

[0434] The processing unit is used to determine the state parameter of the milk storage container corresponding to the differential capacitor sensor assembly according to the digital signal and a preset mapping relationship.

[0435] The structure of the control circuit is only illustrative. In some embodiments, the control circuit can further include more or less components than those shown, or combine certain components, or split certain components, or different arrangement of components. The components shown can be implemented in hardware, software, or a combination of software and hardware. For example, part or all of the functions of the conversion unit can be integrated into the processing unit to save space, or the processing unit can be added to the conversion unit, which is not limited in the present application.

[0436] An embodiment of the electrode type capacitive sensor assembly for detecting the liquid level will be described below.

[0437] Referring to FIG. 46, FIG. 46 is a schematic diagram of the liquid level detection principle of the differential capacitive sensor assembly according to an embodiment of the present application. The control circuit is not shown in FIG. 46.

[0438] As shown in FIG. 46, FIG. 46 includes straight electric field lines that point from the facing plane of the first electrode 1000 to the facing plane of the second electrode 2000, and also includes curved electric field lines that point from the side of the first electrode 1000 to the side of the second electrode 2000. The curved electric field lines pass through the liquid storage space of the container, because the dielectric constant of the liquid is much larger than that of the air, so as the liquid level rises, the dielectric constant between the two electrodes gradually increases, so that the capacitance value of the parallel capacitor group increases.

[0439] It can be understood that only part of the electric field lines of the parallel capacitor group are shown in FIG. 46.

[0440] The capacitance change of the differential capacitive sensor assembly in FIG. 46 is proportional to the change of the liquid level, or in other words, the capacitance change of the differential capacitive sensor assembly is proportional to the change of the liquid volume in its detection area. Therefore, after converting the capacitance change into a specific digital signal change, the specific change amount of the liquid level or the liquid volume can be calculated according to the digital signal change.

[0441] Optionally, a shielding layer 3000 is further provided on the side of the first electrode and the second electrode away from the container, so as to reduce external interference. It is defined that the first electrode and the second electrode detect the liquid level of the container through the electric field lines on the first side. The above case can also be understood as that a shielding layer is provided near the second side opposite to the first side, which blocks the electric field lines on the second side, so as to reduce external interference.

[0442] In FIG. 46, d1 is the distance between the two facing planes of the first electrode and the second electrode, and d2 is the distance between the first electrode and the second electrode and the liquid storage space of the container. The distance d1 between the two facing planes of the first electrode and the second electrode of the parallel capacitor group is referred to as the pitch of the differential capacitive sensor assembly. The pitch d1 of the parallel capacitor group is proportional to the detection distance. In order to ensure that the differential capacitive sensor assembly can detect the change of the liquid level of the liquid storage space, it is necessary to ensure that d1 is greater than or equal to d2.

[0443] For example, assuming that the maximum detection distance of the parallel capacitor group in FIG. 46 is d2, when the container is far away from the differential capacitive sensor assembly, so that the distance between the container and the differential capacitive sensor assembly is greater than d2, the pitch d1 can be increased, thereby increasing the detection range of the parallel capacitor group.

[0444] In FIG. 43, the flow detection sensor 41, the interference shielding structure 44, the first interference detection sensor 43, and the second interference detection sensor 42 are included.

[0445] In a possible implementation, the flow interference elimination device is the interference shielding structure 44, and the interference shielding structure 44 shields at least part of the flow detection interference. The flow detection interference at least includes the milk storage container stored milk amount interference.

[0446] In the interference shielding structure 44, the capacitive detection sensor includes a detection surface close to the milk flow path and an interference surface close to the milk storage container, and the interference shielding structure 44 includes an interference shielding layer, and the interference shielding layer is arranged at least on the interference surface of the capacitive detection sensor.

[0447] Preferably, the interference shielding layer is arranged on all surfaces except the detection surface close to the milk flow path.

[0448] Optionally, the interference shielding layer is made of a metal material, or is a conductive coating, a composite shielding material, etc., which is not limited in the application.

[0449] In another possible implementation, the flow interference elimination device is an interference detection sensor, and the interference detection sensor is used to detect the interference received by the flow detection sensor.

[0450] Optionally, the interference detection sensor includes a capacitive sensor, and the capacitive detection sensor detects the flow interference capacitance value.

[0451] Further, the interference detection sensor is a differential capacitive sensor assembly, and the differential capacitive sensor assembly detects the flow interference capacitance value.

[0452] In the first example, the interference detection sensor is the first interference detection sensor 43, the detection value of the first interference detection sensor 43 is not affected by the flow, but only affected by the external interference, especially the milk stored in the milk storage container, so that the detection value of the first interference detection sensor 43 is equal to the interference value of the flow detection sensor 41.

[0453] In the second example, the interference detection sensor is the second interference detection sensor 42, the second interference detection sensor 42 is affected by both the flow and the external interference, for example, when a hand touches, the dielectric constants of the flow detection sensor 41 and the second interference detection sensor 42 change to the same dielectric constant at the same time.

[0454] Therefore, the second interference detection sensor 42 can be used to detect the detection value corresponding to the unit volume of milk, and according to the detection value corresponding to the unit volume of milk and the detection value of the flow detection sensor, the volume of the milk in the detection area of the flow detection sensor at the current time can be accurately determined, and according to the volume of the milk in the detection area of the flow detection sensor at the current time and the volume of the milk in the detection area of the flow detection sensor at the last time, the accurate flow in the milk flow path can be determined.

[0455] Further, after the milk flows out of the breast, it flows into the milk storage container along the flow path direction in the milk flow path, and the interference detection sensor is arranged in front of the flow detection sensor in the flow path direction.

[0456] In the present application, the flow detection sensor and the interference detection device are preferably a detection mode that does not contact the milk.

[0457] Optionally, the milk flow path includes an outer wall that does not contact the milk and an inner wall that contacts the milk; the flow detection sensor is arranged on the outer wall of the milk flow path, or arranged on the side of the outer wall of the milk flow path away from the inner wall of the milk flow path.

[0458] Optionally, the flow interference elimination device is arranged on the outer wall of the milk flow path, or arranged on the side of the outer wall of the milk flow path away from the inner wall of the milk flow path that contacts the milk.

[0459] Therefore, non-contact flow detection and interference detection are realized.

[0463] In addition, the differential capacitive sensor assembly 46 can be arranged as a separate accessory and detachably arranged on the breast shield 111 or the host 110, and the present application does not make any limitation.

[0464] In addition, only the detection electrode assembly in the differential capacitive sensor assembly 46 is shown in FIG. 47, and the control circuit is not shown, but this does not mean that the differential capacitive sensor assembly 46 does not need a control circuit. The control circuit can be arranged in the same area as the electrode 461 and the electrode 462, for example, both arranged in the breast shield 111. The control circuit can be arranged in a different area from the electrode 461 and the electrode 462, for example, arranged in the host 110 and connected to the electrode 461 and the electrode 462 through a connecting line. The present application does not make any limitation.

[0465] The differential capacitive sensor assembly 45 includes an electrode 451 and an electrode 452. It can be understood that the electrode 451 and the electrode 452 in FIG. 47 are arranged on the same side of the breast shield 111, and the electrode 451 and the electrode 462 can be arranged on different sides of the breast shield 111.

[0466] In addition, the differential capacitive sensor assembly 45 can also be arranged in the host 110, and is not limited to being arranged in the breast shield 111.

[0467] In addition, the differential capacitive sensor assembly 45 can be arranged as a separate accessory and detachably arranged on the breast shield 111 or the host 110, and the present application does not make any limitation.

[0468] In addition, only the detection electrode assembly in the differential capacitive sensor assembly 45 is shown in FIG. 47, and the control circuit is not shown, but this does not mean that the differential capacitive sensor assembly 45 does not need a control circuit. The control circuit can be arranged in the same area as the electrode 451 and the electrode 452, for example, both arranged in the breast shield 111. The control circuit can be arranged in a different area from the electrode 451 and the electrode 452, for example, arranged in the host 110 and connected to the electrode 451 and the electrode 452 through a connecting line. The present application does not make any limitation.

[0469] Please refer to Fig. 48, Fig. 49 and Fig. 50 again, Fig. 48 is a perspective view of another embodiment of the fourth breast pump of the present application, Fig. 48 is a first exploded view of another embodiment of the fourth breast pump of the present application, and Fig. 50 is a second exploded view of another embodiment of the fourth breast pump of the present application.

[0470] As shown in Fig. 48 to Fig. 50, the breast pump 1 comprises a breast shield 10, a milk storage container 20 and a main machine 30.

[0471] The breast shield 10 is used to cover the human breast and fit the breast. The breast shield 10 is a flange in the shape of a horn for fitting the breast, and the milk storage container 20 comprises a breast passage 22 for accommodating the nipple.

[0472] The milk storage container 20 is used to receive and store the breast milk collected by the breast shield 10, and the milk storage container 20 is in communication with the breast shield 10.

[0473] Optionally, the milk storage container 20 comprises a milk cover, a milk bowl, a milk bottle and the like, which are not limited by the present application.

[0474] The main machine 30 is also provided with a negative pressure mechanism, which can directly or indirectly apply negative pressure to the breast shield 10 to suck the breast milk into the milk storage container 20.

[0475] The negative pressure mechanism comprises but is not limited to a piezoelectric pump, a diaphragm pump, a hydraulic pump, a mechanical pump and the like.

[0476] Optionally, the main machine 30 can also comprise one or more of the following components: an energy supply module, a negative pressure gas circuit, a control circuit board, a solenoid valve and the like.

[0477] The energy supply module is used to provide energy for the negative pressure mechanism to support the work of the negative pressure mechanism. Specifically, the energy supply module can be a storage battery, a dry battery, or can be directly connected to an external power supply through a power line.

[0478] The main machine 30 is also provided with a mounting hole 32, and the breast shield 10 is arranged in the main machine through the mounting hole 32 and is in liquid communication with the milk storage container 20. The breast milk sucked out by the breast shield 10 flows into the milk storage container 20 after flowing into the one-way valve assembly 24.

[0479] The milk storage container 20 comprises a milk storage container shell 21, a breast passage 22, a negative pressure chamber 23, a one-way valve assembly 24, a diaphragm cover 25 and an air hole 26.

[0480] The milk storage container shell 21 comprises a first shell 211 and a second shell 212, and the second shell 212 is attached to or close to the main machine 30. The first shell 211 can be integrally formed with the second shell 212, or can be detachably mounted with the second shell 212. The mounting edges of the first shell 211 and the second shell 212 are provided with sealing rings or other sealing mechanisms to ensure that the milk liquid does not leak from the mounting edges.

[0481] The negative pressure cabin 23 comprises a diaphragm (not shown in the figure), and the diaphragm cover 25 is fixedly installed on the negative pressure cabin 23 and seals the diaphragm. The diaphragm cover 25 also has an air hole 26 reserved thereon, and the main machine 30 is also provided with a negative pressure socket 38 which is inserted into the air hole 26. Thus, the negative pressure is indirectly applied to the negative pressure cabin 23 through the diaphragm, so that the user produces milk liquid which is collected by the breast shield 10.

[0482] The milk liquid collected by the breast shield 10 enters the milk storage space through the one-way valve assembly 24. The breast pump 1 works in a cycle of milk suction and air intake. When the breast pump 1 works for milk suction, the valve of the one-way valve in the one-way valve assembly 24 is closed, and when the breast pump 1 works for air intake, the valve of the one-way valve in the one-way valve assembly 24 is opened.

[0483] Optionally, the part of the main machine shell which is attached to and / or close to the milk storage container is the main machine shell 31; preferably, the differential capacitive sensor assembly is arranged inside the main machine shell to provide better protection for the sensor.

[0484] In the figure 49, the flow detection sensor 52 and the flow interference elimination device are included. The flow interference elimination device comprises an interference detection sensor 51 and an interference shielding structure 53.

[0485] The interference detection sensor 51, the flow detection sensor 52 and the interference shielding structure 53 are all arranged on the outer side of the milk flow path which does not contact the milk liquid. Liquid blocking spaces or liquid blocking materials can also be arranged on the interference detection sensor 51, the flow detection sensor 52 and the interference shielding structure 53 to prevent the interference detection sensor 51, the flow detection sensor 52 and the interference shielding structure 53 from directly contacting the milk liquid in the milk storage container 20.

[0486] Further, the flow detection sensor 52 can also be arranged in the main machine 30 along the axial direction of the mounting hole 32, or in the breast shield 10, etc. The present application does not make any limitation.

[0487] The capacitive sensor assembly in the present application is not limited to the integrated breast pump in which the main machine and the milk bowl are integrated, but can also be implemented in a split type breast pump in which the main machine and the milk storage container are not integrated or not completely integrated. The split type breast pump includes two types:

[0488] The first type is that the breast pumping assembly formed by the breast shield and the milk storage container is integrated on the chest, and the flexible air tube is connected to the main machine with the air pump placed outside or the handheld main machine with the air pump; generally, the flexible air tube is connected to the milk storage container through a connecting cover to directly or indirectly transmit the negative pressure to the breast shield or the milk storage container. Preferably, the capacitive sensor assembly or the differential capacitive sensor assembly in the above embodiment can be integrated on the cover, or the capacitive sensor assembly or the differential capacitive sensor assembly is a separate detachable accessory detachably connected with the milk storage container and transmits signals to the main machine through wires or wireless signals.

[0489] Referring to FIG. 51, FIG. 51 is a structural schematic diagram of the fourth breast pump in another embodiment of the present application. As shown in FIG. 51, FIG. 51 includes a breast pumping assembly 310 and a main machine 320, and the breast pumping assembly 310 includes a breast shield (not shown in the figure), a milk storage container 311, and a negative pressure cabin cover 312.

[0490] The main machine 320 and the negative pressure cabin cover 312 are connected through the flexible air tube to directly or indirectly transmit the negative pressure to the breast shield.

[0491] Further, FIG. 51 also includes a three-way joint 330, through which the main machine 320 can be connected to multiple breast pumping assemblies to simultaneously or individually provide negative pressure for the multiple breast pumping assemblies.

[0492] The sensor assembly 340 in FIG. 51 can be a flow detection sensor or a flow interference elimination device, and the sensor assembly 340 is integrated in the milk storage container 311, and the sensor assembly 340 is preferably detachably installed with the milk storage container 311.

[0493] In a possible implementation, the sensor assembly 340 can also be integrated in the negative pressure cabin cover 312, and the sensor assembly 340 is preferably detachably installed with the negative pressure cabin cover 312.

[0494] The second type is that the breast pumping assembly formed by the breast shield and the milk storage container is integrated on the chest, and the first main machine with the air pump is also integrated on the breast pumping assembly, the first main machine directly or indirectly transmits the negative pressure to the breast shield or the milk storage container, and the first main machine is connected to the second main machine outside through wires, and the second main machine includes a battery and a control panel; preferably, the capacitive sensor assembly or the differential capacitive sensor assembly in the above embodiment can be integrated on the first main machine, or the capacitive sensor assembly or the differential capacitive sensor assembly is a separate detachable accessory detachably connected with the milk storage container and transmits signals to the second main machine through wires or wireless signals.

[0495] The air pump used in the present application includes but is not limited to a diaphragm pump, a piston pump, a piezoelectric pump, etc., and also includes other pumps or negative pressure driving modes that can be applied to the breast pump.

[0496] The breast pump form in the embodiments of the present application is only used for explanation and illustration, and the scope of protection of the present application is not limited to the breast pump form in the embodiments.

[0497] Based on the structure of the breast pump provided in any of the above embodiments, referring to FIG. 52, FIG. 52 is a flowchart of a method for determining the flow rate of a breast pump according to an embodiment of the present application. As shown in FIG. 52, the method 100 includes steps 110-130.

[0498] Step 110: Obtain a first detection value of a flow rate detection sensor.

[0499] The flow rate detection sensor includes one of a capacitive sensor, an ultrasonic sensor, an acoustic sensor, and an optical sensor. For ease of illustration, the subsequent part of the specification takes the flow rate detection sensor as an example of a capacitive sensor.

[0500] In the case where the flow rate detection sensor is a capacitive sensor, the first detection value is a capacitance value of the capacitive sensor.

[0501] Step 120: Obtain a second detection value of a flow rate interference elimination device.

[0502] In the method embodiment, the flow rate interference elimination device is an interference detection sensor. For ease of illustration, the subsequent part of the specification takes the interference detection sensor as an example of a capacitive sensor.

[0503] In the case where the interference detection sensor is a capacitive sensor, the second detection value is a capacitance value of the capacitive sensor.

[0504] Step 130: Determine the final flow rate of the milk based on the first detection value and the second detection value.

[0505] Step 130 includes steps 131-132.

[0506] Step 131: Determine a third detection value based on the first detection value and the second detection value.

[0507] In one possible implementation, if the interference detection sensor is not affected by the flow rate change and is only used to detect the influence of external interference on the flow rate detection sensor, step 131 includes the step of: subtracting the first detection value from the second detection value to obtain the third detection value.

[0508] At this time, the third detection value is used to indicate the true detection value of the flow rate detection sensor.

[0509] The external interference at least includes the interference of the milk in the milk storage container on the flow rate detection sensor.

[0510] In another possible implementation, if the interference detection sensor and the flow detection sensor are both used to detect the flow in the milk flow path, the interference detection sensor and the flow detection sensor are subjected to the same or similar external interference, and therefore the detection value corresponding to a unit volume of milk can be determined by the second detection value of the interference detection sensor and the size of the detection area thereof, the second detection value divided by the detection value corresponding to a unit volume of milk to obtain the volume of milk in the detection area of the flow detection sensor at the moment, i.e., the third detection value, and the volume difference between the current moment and the previous moment divided by the time difference to obtain the flow data.

[0511] At this time, the third detection value is used to indicate the real milk volume in the detection range of the flow detection sensor.

[0512] Step 132: determining the final flow of the milk according to the third detection value.

[0513] In a possible implementation, if the third detection value is used to indicate the real detection value of the flow detection sensor, the step 132 includes the step of: determining the final flow of the milk according to the third detection value and a preset mapping relationship; wherein the preset mapping relationship is used to indicate the corresponding relationship between the plurality of detection values and the plurality of flows.

[0514] It can be understood that the preset mapping relationship is related to the structure of the breast pump, the type of the flow detection sensor, and other factors, and therefore the specific mapping content of the preset mapping relationship is not limited in the present application.

[0515] In the above implementation, the interference detection sensor is used to quantify the specific value of the external interference, thereby eliminating or reducing the influence of the external interference on the flow detection.

[0516] In another possible implementation, if the third detection value is used to indicate the real milk volume in the detection range of the flow detection sensor, the step 132 includes the step of: determining the final flow of the milk at the current moment according to the third detection value at the current moment and the third detection value at the previous moment.

[0517] In the above implementation, the interference detection sensor is used to calculate the detection value of a unit volume of milk, thereby eliminating or reducing the influence of the external interference on the flow detection.

[0518] Please refer to FIG. 53, which is a structural schematic diagram of a flow determination device of a breast pump provided in an embodiment of the present application. The device is applied to the breast pump in any of the above embodiments. As shown in FIG. 53, the flow determination device 100' of the breast pump includes a first acquisition unit 110', a second acquisition unit 120', and a determination unit 130'.

[0519] The first acquisition unit 110' is used to acquire the first detection value of the flow detection sensor.

[0529] It can be understood that FIG. 54 only illustrates an optional structure of the milk suction device, but does not mean that the present application must be applied to the milk suction device with the above-mentioned structure. The milk suction device can also be in the form of a main machine separated from a milk storage container, for example, the main machine is connected to the milk storage container through an air pipe, or the main machine is arranged on the upper part of the milk storage container, and the breast shield is arranged between the main machine and the milk storage container. The structure of the milk storage container is not limited in the present application.

[0530] The milk flow path is shown by a dashed line in FIG. 54, and the flow direction in the milk flow path is indicated by an arrow, along which the milk flows from the udder into the milk storage container 120.

[0531] The flow detection sensor comprises one of a capacitive sensor, an ultrasonic sensor, an acoustic sensor, and an optical sensor. Preferably, when the flow detection sensor is a capacitive sensor, the capacitive sensor is specifically a differential capacitive sensor assembly.

[0532] The differential capacitive sensor assembly is configured to detect mutual capacitance between two electrodes of the capacitive sensor, and the output result is a capacitance change value between the two electrodes or a digital signal converted from the capacitance change value.

[0533] For ease of description, the capacitive sensor formed by the two electrodes arranged in parallel and opposite to each other in the differential capacitive sensor assembly is referred to as a parallel capacitive group. The parallel capacitive group comprises two parallel electrodes arranged opposite to each other.

[0534] In addition, the differential capacitive sensor assembly comprises a control circuit connected to the parallel capacitive group, the control circuit being configured to charge the parallel capacitive group and collect the electric charge on the parallel capacitive group after a preset time, and determine the capacitance value of the parallel capacitive group according to the electric charge change speed and / or the electric charge change amount.

[0535] The control circuit comprises a conversion unit, and the conversion unit comprises an excitation module, a sampling module, and a conversion module.

[0536] The excitation module generates a charging signal for charging the differential capacitive sensor assembly, the electric charge on the differential capacitive sensor assembly is transmitted to the conversion module through the sampling module, and the conversion module converts the analog voltage into a digital signal.

[0538] Optionally, the conversion unit is a capacitive-to-digital converter, and the conversion module is an analog-to-digital converter (ADC).

[0539] In FIG. 54, the flow detection sensor 41 is included. Optionally, the milk flow path comprises an outer wall not in contact with the milk and an inner wall in contact with the milk, and the flow detection sensor is arranged on the outer wall of the milk flow path or on the side of the outer wall of the milk flow path away from the inner wall of the milk flow path.

[0540] Based on any one of the first, second, third, fourth and fifth embodiments, please refer to FIG. 55, which is a flowchart of a milk volume detection method of a breast pump according to an embodiment of the present application. As shown in FIG. 55, the method 200 comprises steps 210-240.

[0541] Step 210: Obtain the milk volume data curve of the milk volume sensor.

[0542] The milk volume sensor includes but is not limited to a differential capacitance sensor, a photoelectric sensor, an ultrasonic sensor, etc. The present application does not limit the way of obtaining the milk volume data.

[0543] In a possible implementation, please refer to FIG. 56, which is a schematic diagram of a first milk volume data curve according to an embodiment of the present application. As shown in FIG. 56, the first milk volume data curve is a curve of the relationship between the milk volume and time.

[0544] In another possible implementation, please refer to FIG. 57, which is a schematic diagram of a second milk volume data curve according to an embodiment of the present application. As shown in FIG. 57, the second milk volume data curve is a curve of the relationship between the milk volume increment and time.

[0545] Step 220: Obtain the flow data curve of the flow sensor.

[0546] The milk flow path includes but is not limited to at least one of the flange in the breast shield, the nipple passage in the breast shield, the negative pressure chamber, the one-way valve, and the nipple passage in the milk storage container.

[0547] In a possible implementation, the flow data is the flow data of a certain region of the milk flow path, for example, the length of the milk flow path is 10 cm, and only the flow of the milk flow path in the range of 2 cm-4 cm is detected to obtain the flow data.

[0548] In another possible implementation, the flow data is the flow data of the entire milk flow path.

[0549] The flow data curve is a curve of the relationship between the milk flow in the milk flow path of the breast pump and time. Please refer to FIG. 58, which is a schematic diagram of a flow data curve according to an embodiment of the present application.

[0550] Optionally, the first preset time range can be the same as the second preset time range. Preferably, the first preset time range and the second preset time range have the same length of time, but the time start point of the second preset time range lags behind the time start point of the first preset time range, and the difference between the two time start points is determined by the time required for the milk to flow from the detection position of the flow sensor in the milk flow path into the storage container.

[0551] Step 230: Determine whether the milk volume data curve and the flow data curve match.

[0552] In the case where the milk volume data curve is a curve of the storage volume of milk versus time:

[0553] In one possible implementation, step 230 includes determining whether the milk volume data curve and the flow data curve match according to the flow range in which the flow in the flow data curve is located and the slope in the milk volume data curve.

[0554] The slope in the milk volume data curve reflects the increasing speed of the milk volume. When the increasing speed of the milk volume is greater than zero, it reflects that the milk volume is rising. When the increasing speed of the milk volume is equal to zero, it reflects that the milk volume is constant. In general, the increasing speed of the milk volume will not be negative, unless the user actively pours out the milk.

[0555] Therefore, if the flow in the flow data curve is in the first flow range, the slope in the milk volume data curve is in the first slope range, and if the flow in the flow data curve is in the second flow range, the slope in the milk volume data curve is in the second slope range, it is determined that the milk volume data curve and the flow data curve match; wherein the first flow range and the second flow range are different, and the first slope range and the second slope range are different.

[0556] Optionally, the first flow range is (a preset flow value, an upper flow limit value], and the first slope range is (a preset slope value, an upper slope limit value]. Exemplarily, the preset flow value and the preset slope value can both be zero, reflecting that when the flow is greater than zero, the milk volume should rise.

[0557] However, because the flow sensor and the milk volume sensor can be disturbed by external interference, the detected flow and the detected storage volume of milk can be in a state of small fluctuations all the time, so the preset flow value is preferably zero plus a first preset allowable fluctuation value, and the preset slope value is preferably zero plus a second preset allowable fluctuation value. The first preset allowable fluctuation value and the second preset allowable fluctuation value can be selected as needed, and the present application does not limit them.

[0558] And the human milk ejection speed cannot be infinite, so the first flow range sets a flow upper limit value, and the first slope range sets a slope upper limit value, so that external interference can be excluded, for example, when both the flow sensor and the milk volume sensor are capacitive sensors, they are affected by human touch at the same time, which may cause the flow to be greater than the flow upper limit value and the slope to be greater than the slope upper limit value.

[0559] In another possible implementation, step 230 includes: calculating a first area of a region formed by the flow data curve and the time axis, determining a first milk volume according to the first area; determining a second milk volume according to the milk volume data curve; and determining whether the milk volume data curve and the flow data curve match according to the first milk volume and the second milk volume.

[0560] Optionally, when the difference between the first milk volume and the second milk volume is within a preset difference range, it is determined that the milk volume data curve and the flow data curve match.

[0561] The above implementation can detect the case where one of the milk volume sensor and the flow sensor is disturbed and the detected value is abnormal, thereby improving the milk volume detection accuracy.

[0562] In the case where the milk volume data curve is a curve of the milk storage amount increment versus time:

[0563] In one possible implementation, step 230 includes: determining whether the milk volume data curve and the flow data curve are consistent in trend in a preset detection time range.

[0564] Optionally, at least one of the following conditions is met, and it is considered that the two curves are consistent in trend:

[0565] (1) When the slope of the milk volume data curve is greater than zero, the slope of the flow data curve is greater than zero. (2) When the slope of the milk volume data curve is less than or equal to zero, the slope of the flow data curve is less than or equal to zero.

[0566] Among them, the flow data change will be ahead of the milk storage amount data change, because the milk needs to pass through the milk flow path to flow into the milk storage container, so when the flow data change is detected, the milk may not have flowed into the milk storage container, at this time the milk storage amount data of the milk storage container has not changed. Therefore, the milk volume data curve may lag behind the flow data curve as a whole.

[0567] Optionally, when judging whether the milk volume data curve and the flow data curve are consistent in the preset detection time range segment, it is judged whether the milk volume data curve in the first preset detection time range segment and the flow data curve in the second preset detection time range segment are consistent. The first preset detection time range segment and the second preset detection time range segment have the same time length, but the time starting point of the second preset detection time range segment lags behind the time starting point of the first preset detection time range segment, and the difference between the two time starting points is determined by the time required for the milk liquid to flow from the detection position of the flow sensor in the milk flow path into the milk storage container.

[0568] In another possible implementation, step 230 includes judging whether the wave peak and the wave trough time positions of the milk volume data curve in the preset detection time range segment are consistent.

[0569] The wave peak refers to a point on the curve, and the function value of the point is greater than that of its adjacent points. The milk volume data curve in the preset detection time range segment usually has at least one wave peak.

[0570] The wave trough refers to a point on the curve, and the function value of the point is less than that of its adjacent points. The milk volume data curve in the preset detection time range segment has at least one wave trough.

[0571] The flow data change will be ahead of the milk storage volume data change, because the milk liquid needs to flow through the milk flow path to flow into the milk storage container, so when the flow data change is detected, the milk liquid may not have flowed into the milk storage container, and at this time, the milk storage volume data in the milk storage container has not changed. Therefore, the milk volume data curve may lag behind the flow data curve as a whole.

[0572] Optionally, judging whether the wave peak and the wave trough time positions of the milk volume data curve in the preset detection time range segment are consistent is judging whether the difference between the wave peak and the wave trough times of the milk volume data curve in the preset detection time range segment is a preset difference value. The preset difference value is determined by the time required for the milk liquid to flow from the detection position of the flow sensor in the milk flow path into the milk storage container.

[0573] Step 240: determining the milk volume of the breast pump according to the judgment result.

[0574] Further, in this application, if the milk volume at a certain time is to be determined, the milk volume data curve and the flow data curve before the time are needed to be obtained, and it is judged whether the two are matched.

[0575] At this time, step 230 includes the step of judging whether the milk volume data curve and the flow data curve from the first time to the second time are matched. Step 240 includes the step of determining the milk volume of the breast pump at the second time according to the judgment result.

[0576] Therefore, the milk volume data curve and the flow data curve need to be matched at each time in the present application, so as to ensure the accuracy of each milk volume finally displayed.

[0577] In the case of a failed check: determining the milk volume of the breast pump based on at least one of the milk storage volume data and the flow data.

[0578] In one possible implementation, the milk storage volume data at the time of the last successful check is determined as the milk volume of the breast pump. For example, the check at 9S is successful, and the check at 10S is failed, and the milk storage volume at 9S is determined as the milk storage volume at 10S.

[0579] In another possible implementation, the average flow is determined based on the flow data, and the length of time of the flow data is determined; and the milk volume of the breast pump is calculated according to the average flow and the length of time. Therefore, when the milk volume sensor is disturbed, the correct milk storage volume is calculated based on the flow data, and the accuracy of the milk volume detection of the breast pump is improved.

[0580] In the case of a successful check, the current milk volume in the milk storage volume data detected by the milk volume sensor is determined as the milk volume of the breast pump.

[0581] Optionally, the milk volume detection method of the breast pump provided in the present application further includes the step of: in the case of a failed check, performing a preset operation.

[0582] The preset operation includes any one or more of the following.

[0583] (1) controlling the display module in the breast pump to pause updating the milk volume calculated based on the milk storage volume data;

[0584] (2) pausing sending the milk volume calculated based on the milk storage volume data to an electronic device in communication with the breast pump.

[0585] (3) controlling the display module in the breast pump to display prompt information.

[0586] (4) sending indication information to an electronic device in communication with the breast pump, the indication information being used to instruct the display module of the electronic device to display prompt information.

[0587] (5) controlling the display module in the breast pump to display the milk volume calculated based on the flow data.

[0588] (6) sending the milk volume calculated based on the flow data to an electronic device in communication with the breast pump.

[0589] Optionally, the display module in the breast pump is a display screen in the breast pump. The display screen in the breast pump is usually arranged in the main machine.

[0590] Optionally, the breast pump communicates with the electronic device through a data line and / or through a wireless communication module, such as a Bluetooth module or a WIFI module.

[0591] Optionally, the display module of the electronic device is a display screen of the electronic device.

[0592] Please refer to FIG. 59, which is a structural schematic diagram of a milk volume detection device of a breast pump according to an embodiment of the present application. As shown in FIG. 59, the milk volume detection device 200' of the breast pump comprises a first acquisition unit 210', a second acquisition unit 220', a judgment unit 230', and a determination unit 240'.

[0593] The first acquisition unit 210' is configured to acquire a milk volume data curve of the milk volume sensor.

[0594] The second acquisition unit 220' is configured to acquire a flow data curve of the flow sensor.

[0595] The judgment unit 230' is configured to judge whether the milk volume data curve and the flow data curve match.

[0596] The determination unit 240' is configured to determine the milk volume of the breast pump according to the judgment result.

[0597] Any of the above units can also perform the remaining steps of the milk volume detection method of the breast pump in any of the embodiments described in the specification, or the milk volume detection device 200' of the breast pump is further provided with the remaining units to perform the remaining steps of the milk volume detection method of the breast pump in any of the embodiments described in the specification, which will not be described here.

[0598] Based on any of the first, second, third, fourth, and fifth embodiments described above, please refer to FIG. 60, which is a flowchart of a milk volume detection method of a breast pump according to an embodiment of the present application. As shown in FIG. 60, the method 300 comprises steps 310 to 340.

[0599] Step 310: Acquire flow data of a flow sensor; the flow sensor detects flow data of milk liquid in a milk flow path of the breast pump.

[0600] The flow data comprises flow and collection time corresponding to each flow.

[0601] The flow path segment through which the milk liquid flows from the breast to the storage container is a milk flow path. The milk flow path comprises, but is not limited to, at least one of a flange in a breast shield, a nipple passage in the breast shield, a negative pressure chamber, a one-way valve, and a nipple passage in the storage container.

[0602] In a possible implementation, the flow data is flow data of a certain region of the milk flow path, for example, the length of the milk flow path is 10 cm, and only the flow of the milk flow path in the range of 2-4 cm is detected to obtain the flow data.

[0603] In another possible implementation, the flow data is flow data of the entire milk flow path.

[0604] Step 320: Obtain milk storage amount data of the milk storage sensor; the milk storage sensor detects the current milk storage amount data of the milk storage container.

[0605] The milk storage amount data includes milk storage amount and collection time corresponding to each milk storage amount.

[0606] In the current breast pump, a milk storage sensor is usually arranged to detect the milk storage amount in the milk storage container, so as to obtain the milk storage amount data. The milk storage sensor includes but is not limited to a differential capacitive sensor, a photoelectric sensor, an ultrasonic sensor, etc. The application does not limit the acquisition method of the milk storage amount data.

[0607] Step 330: Verify the milk storage amount data according to the flow data, and determine a verification result.

[0608] The flow data change will be ahead of the milk storage amount data change, because the milk needs to pass through the milk flow path to flow into the milk storage container, so when the flow data change is detected, the milk may not have flowed into the milk storage container, and at this time, the milk storage amount data of the milk storage container has not changed. Therefore, the flow and the average flow determined according to the flow data in the subsequent application are in the first preset time range, and the milk amount acceleration and the milk amount increase determined according to the milk storage amount data in the subsequent application are in the second preset time range.

[0609] The first preset time range can be the same as the second preset time range. However, preferably, the first preset time range and the second preset time range have the same time length, but the time start point of the second preset time range lags behind the time start point of the first preset time range, and the difference between the two time start points is determined by the time required for the milk to flow from the detection position of the flow sensor in the milk flow path into the milk storage container.

[0610] The application has various ways of verifying the milk storage amount data according to the flow data, which will be described in detail below.

[0611] In a possible implementation, the step 330 comprises the following steps: determining the flow in the first preset time range according to the flow data; determining the milk amount acceleration in the second preset time range according to the milk amount data; determining that the verification result is a verification pass if the flow and the milk amount acceleration meet the first preset condition; and determining that the verification result is a verification fail if the flow and the milk amount acceleration do not meet the first preset condition.

[0612] The milk amount acceleration is the increasing speed of the milk amount, for example, the volume of the milk amount increased in 1 second or the size of the liquid level increased in 1 second.

[0613] The first preset condition comprises any one or more of the following:

[0614] (1) In the case of increasing flow, i.e., the flow acceleration is greater than zero, the increasing speed of the milk amount increases.

[0615] (2) In the case of decreasing flow, i.e., the flow acceleration is less than zero, the increasing speed of the milk amount decreases.

[0616] (3) In the case of constant flow, i.e., the flow acceleration is equal to zero, the milk amount acceleration is constant.

[0617] Further, the milk amount acceleration increasing can be that the milk amount acceleration is greater than zero or the milk amount acceleration is greater than a first preset acceleration; the milk amount acceleration decreasing can be that the milk amount acceleration is less than zero or the milk amount acceleration is less than a second preset acceleration; and the milk amount acceleration being constant can be that the milk amount acceleration is equal to zero or the milk amount acceleration is within a range from the second preset acceleration to the first preset acceleration; wherein the first preset acceleration is greater than zero and greater than the second preset acceleration. Because the flow sensor can be disturbed by the outside world, the detected flow acceleration can be in a small fluctuation state all the time, so it is preferred to determine whether the first preset condition is met by using the first preset acceleration and the second preset acceleration.

[0618] The specific values of the first preset acceleration and the second preset acceleration can be selected as needed, and the present application does not limit them.

[0619] In some cases, all the flow and all the milk amount meet the first preset condition, and the verification passes. In other cases, a preset percentage of the flow and the milk amount meet the first preset condition, and the verification passes. For example, the time length of the first preset time range and the second preset time range is 3 seconds, and the preset percentage is 90%, so as long as the time in which the flow and the milk amount acceleration meet the first preset condition is more than 2.7 seconds in 90% of the time, the verification is determined to pass. The preset percentage can be selected as needed, and will not be described here.

[0620] In another possible implementation, the step 330 comprises the steps of: determining the flow in the first preset time range according to the flow data; determining the milk amount increase in the second preset time range according to the milk amount data; determining that the verification result is a verification pass in a case where the flow and the milk amount increase meet a second preset condition; and determining that the verification result is a verification fail in a case where the flow and the milk amount increase do not meet the second preset condition.

[0621] The second preset condition comprises any one or more of the following:

[0622] (1) In a case where the flow is greater than a preset flow, the milk amount increase is greater than a preset increase.

[0623] (2) In a case where the flow is less than or equal to the preset flow, the milk amount increase is less than or equal to a preset increase.

[0624] Optionally, the preset flow and the preset increase are both zero. That is, when the flow is greater than zero, it means that milk flows into the milk storage container, and thus the milk amount increase in the milk storage container is greater than zero.

[0625] However, because the flow sensor can be disturbed by the outside world, the detected flow can be in a small fluctuation state all the time, and thus the preset flow is preferably zero plus a first preset allowable fluctuation value, and the preset increase is preferably zero plus a second preset allowable fluctuation value. The first preset allowable fluctuation value and the second preset allowable fluctuation value can be selected as needed, and the present application does not limit them.

[0626] In yet another possible implementation, the step 330 comprises the steps of: determining an average flow in the first preset time range according to the flow data; determining a first milk amount increase according to the average flow and a time length of the first preset time range; determining a second milk amount increase in the second preset time range according to the milk amount data; determining that the verification result is a verification pass in a case where the first milk amount increase and the second milk amount increase meet a third preset condition; and determining that the verification result is a verification fail in a case where the first milk amount increase and the second milk amount increase do not meet the third preset condition.

[0627] The third preset condition comprises any one of the following:

[0628] (1) A difference between the first milk amount increase and the second milk amount increase is within a preset difference range.

[0629] (2) The difference between the first milk amount increase and the second milk amount increase is within the preset difference range, and both the first milk amount increase and the second milk amount increase are less than a preset upper limit value.

[0630] In some cases, the difference between the first milk volume increase amount and the second milk volume increase amount is within the preset difference range, which can also be that the flow sensor and the milk volume sensor are simultaneously disturbed by external interference, so that the detection values are simultaneously increased, for example, when the flow sensor and the milk volume sensor are both capacitive sensors, they can be simultaneously touched by a hand, so that the capacitive detection values are simultaneously increased. Therefore, condition (2) in the third preset condition introduces a preset upper limit value, so as to detect the case that the two are disturbed by external interference, and further improve the milk volume detection accuracy.

[0631] Step 340: determining the milk volume of the breast pump according to the verification result.

[0632] In the case of verification failure: determining the milk volume of the breast pump based on at least one of the storage milk volume data and the flow data.

[0633] In one possible implementation, the storage milk volume data at the last time of successful verification is determined as the milk volume of the breast pump. For example, the verification at 9S is successful, and the verification at 10S is failed, and the storage milk volume at 9S is taken as the storage milk volume at 10S.

[0634] In another possible implementation, the average flow is determined based on the flow data, and the time length of the flow data is determined; and the milk volume of the breast pump is calculated according to the average flow and the time length. Thus, when the milk volume sensor is disturbed, the correct storage milk volume is calculated by using the flow data, and the milk volume detection accuracy of the breast pump is improved.

[0635] In the case of successful verification, the current milk volume in the storage milk volume data detected by the milk volume sensor is determined as the milk volume of the breast pump.

[0636] Optionally, the milk volume detection method of the breast pump provided in the present application further comprises the step of: in the case of verification failure, performing a preset operation.

[0637] The preset operation includes any one or more of the following.

[0638] (1) controlling the display module in the breast pump to pause updating the milk volume calculated according to the storage milk volume data;

[0639] (2) pausing sending the milk volume calculated according to the storage milk volume data to an electronic device in communication with the breast pump.

[0640] (3) controlling the display module in the breast pump to display prompt information.

[0641] (4) sending indication information to an electronic device in communication with the breast pump, the indication information being used to instruct the display module of the electronic device to display prompt information.

[0642] (5) controlling the display module in the breast pump to display the milk volume calculated according to the flow data.

[0643] (6) sending the milk volume calculated according to the flow data to an electronic device in communication with the breast pump.

In some embodiments, the memory 720 can optionally include a memory remotely arranged with respect to the processor 710, and these remote memories can be connected to the controller through a network. Examples of the above network include but are not limited to the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0659] Based on the breast pump provided in any of the above first, second, third, fourth and fifth embodiments, please refer to FIG. 63, which is a flowchart of a recommended breast pumping method of the breast pump according to an embodiment of the present application. As shown in FIG. 63, the recommended breast pumping method 400 of the breast pump includes steps 410 to 420.

[0660] Step 410: obtaining a plurality of historical breastmilk pumping data, the breastmilk pumping data at least comprising breastmilk pumping parameter data of a plurality of historical breastmilk pumping periods or breastmilk pumping parameter data in a plurality of preset breastmilk pumping time periods.

[0661] The breastmilk pumping period in the breastmilk pump comprises: a complete breastmilk pumping process of each mode, a complete breastmilk pumping process in which the user sets a breastmilk pumping volume target.

[0662] The breastmilk pump has at least one breastmilk pumping mode that can be directly invoked by the user. Optionally, the user invokes the mode for a breastmilk pumping, and a complete breastmilk pumping process is not terminated in the middle (it can be paused and then continued). Optionally, the breastmilk pumping time or the pumped milk volume of the user invoking the mode reaches a standard (it can be terminated after reaching the standard), and the breastmilk pumping process is not considered a complete breastmilk pumping process.

[0663] The breastmilk pumping parameter data at least comprises one or more of the following: breastmilk pumping gear data, breastmilk pumping frequency data, breastmilk pumping mode data, breastmilk pumping time length data, breastmilk pumping period total breastmilk pumping volume data, breastmilk pumping volume curve data, breastmilk pumping flow curve data, and user breastmilk pumping process body physiological monitoring data.

[0664] Specifically, the breastmilk pump is provided with a plurality of gears, and at least one of the breastmilk pumping intensity and the breastmilk pumping frequency is different in different gears.

[0665] Specifically, the breastmilk pump is provided with a plurality of modes, such as a lactation mode, a breastmilk pumping mode, and a mixed mode.

[0666] Specifically, the breastmilk pumping volume curve data reflects the change of the lactation volume of the mother at different times, and can be a curve with one coordinate axis being time and the other coordinate axis being the milk volume stored in the storage container.

[0667] Specifically, the breastmilk pumping flow curve data reflects the change of the flow of the milk liquid in the breastmilk pumping process. The flow path segment from the flow of the milk liquid out of the breast to the flow of the milk liquid into the milk storage container is defined as a milk flow path. The flow on the milk flow path can be measured to obtain the breastmilk pumping flow curve data.

[0668] Specifically, the user breastmilk pumping process body physiological monitoring data comprises at least one of the following: heartbeat monitoring data, pulse monitoring data, blood pressure monitoring data, respiration monitoring data, skin response monitoring data, expression monitoring data, and blood oxygen saturation data.

[0669] Each recommended breast pumping data corresponds to a breast pumping parameter in a breast pumping cycle or a breast pumping period that can be called. The breast pumping parameter can be used to control the breast pump to work, thereby providing a breast pumping mode that is most suitable for the user and different from the preset mode. The breast pumping parameter includes one or more of the breast pumping time, the suction force, the breast pumping frequency, and the called breast pumping component. The breast pumping component that can be called in the breast pump includes a massage component, a hot compress component, etc., which are not limited in the present application.

[0670] In some cases, the plurality of historical breast pumping data is derived from the same user or the plurality of historical breast pumping data of the same breast pump. In other cases, the plurality of historical breast pumping data is derived from the plurality of users or the plurality of historical data of the plurality of breast pumps, such as the plurality of historical data derived from the cloud data stored in the server.

[0671] Step 420: generating at least one recommended breast pumping data according to the breast pumping parameter data of the plurality of historical breast pumping cycles or the breast pumping parameter data in the plurality of preset breast pumping periods. Each recommended breast pumping data corresponds to a breast pumping parameter in a breast pumping cycle or a breast pumping period that can be called.

[0672] In one possible implementation, step 420 includes the step of: determining, according to the breast pumping parameter data of the plurality of historical breast pumping cycles or the breast pumping parameter data in the plurality of preset breast pumping periods, the breast pumping data with the highest breast milk extraction efficiency in a historical breast pumping cycle or the breast pumping data with the highest breast milk extraction efficiency in a preset breast pumping period as the recommended breast pumping data.

[0673] The breast pumping parameter of the recommended breast pumping data can be a copy of the breast pumping parameter in the historical breast pumping cycle corresponding to the breast pumping data with the highest breast milk extraction efficiency, or a copy of the breast pumping parameter in the preset breast pumping period with the highest breast milk extraction efficiency.

[0674] According to the different breast pumping parameter data, there are different methods to determine the breast pumping data with the highest breast milk extraction efficiency.

[0675] In some cases, the breast pumping data with the highest breast milk extraction efficiency is the breast pumping data with the highest breast milk volume in a breast pumping cycle or a preset breast pumping period calculated according to the breast milk flow curve data.

[0676] The area enclosed by the flow curve and the time axis in the breast milk flow curve data is the breast milk volume.

[0677] In other cases, the breast pumping data with the highest breast milk extraction efficiency is the breast pumping data with the highest breast milk volume in a breast pumping cycle or a preset breast pumping period calculated according to the breast milk volume data or the breast milk volume curve data.

[0678] The above implementation can recommend the breast pumping mode with the highest breast pumping efficiency to the user.

[0679] In another possible implementation, step 420 comprises the step of determining, according to the milk pumping parameter data of a plurality of historical milk pumping periods or the milk pumping parameter data in a plurality of preset milk pumping time periods, the most comfortable milk pumping data of the user in a historical milk pumping period or the most comfortable milk pumping data of the user in a preset milk pumping time period as the recommended milk pumping data.

[0680] The milk pumping parameter of the recommended milk pumping data can be a copy of the milk pumping parameter in the historical milk pumping period corresponding to the most comfortable milk pumping data of the user or a copy of the milk pumping parameter in the preset milk pumping time period corresponding to the most comfortable milk pumping data of the user.

[0681] The most comfortable milk pumping data of the user can be determined by the body physiological monitoring data of the user during the milk pumping process.

[0682] For example, under normal circumstances, if the user feels comfortable, the heart rate and pulse will remain in a relatively stable range with little fluctuation. If the heart rate and pulse increase significantly, it can indicate that the user feels nervous, uncomfortable or in pain.

[0683] For example, during a comfortable milk pumping process, the blood pressure of the user should remain within a normal range with no significant fluctuation. A sudden increase in blood pressure can mean that the user is experiencing discomfort or pain.

[0684] For example, during a comfortable milk pumping process, the user's breathing should be smooth and rhythmic. Rapid or irregular breathing can indicate that the user feels nervous, uncomfortable or in pain.

[0685] For example, during a comfortable milk pumping process, the user's facial expression will usually appear relaxed and happy. If the user has a frown or other expressions, it can indicate that the user is experiencing discomfort or pain.

[0686] For example, under normal circumstances, the blood oxygen saturation should remain above 95%. If the blood oxygen saturation decreases, it can indicate that the user is having difficulty breathing or has other physical problems.

[0687] The above implementation can recommend the most comfortable recommended milk pumping data for the user.

[0688] After obtaining the recommended milk pumping data, the recommended milk pumping data can be automatically applied to the user. At this time, the method 400 of the present application further comprises the step of automatically calling the recommended milk pumping data after the breast pump is turned on and directly executing or executing after the user confirms.

[0689] Optionally, the recommended milk pumping data is automatically called after the breast pump is turned on. If the user does not select a milk pumping mode or adjust a milk pumping gear after the breast pump is turned on, the recommended milk pumping data is automatically applied for milk pumping.

[0690] Optionally, if the user does not select a breast pumping mode or adjust the breast pumping gear after the breast pump is turned on, a confirmation control is displayed on the display screen of the breast pump or the display screen of the electronic device in communication with the breast pump, and the user clicks the confirmation control to apply the recommended breast pumping data for breast pumping.

[0691] Moreover, if there are multiple recommended breast pumping data, the user selects one of the recommended breast pumping data and confirms it to call and execute it. For example, a selection sub-control is set for each recommended breast pumping data in the area where the confirmation control is displayed, and the user selects the selection sub-control corresponding to one of the recommended breast pumping data and clicks the confirmation control to call and execute the recommended breast pumping data.

[0692] In some embodiments, the recommended breast pumping data is displayed in the application program of the breast pump running on the electronic device in communication with the breast pump.

[0693] The recommended breast pumping data can be displayed in the application program of the breast pump running on the electronic device in communication with the breast pump, so that the user can select, delete, or modify the recommended breast pumping data through the application program.

[0694] In some embodiments, the recommended breast pumping data is stored in the breast pump data storage mechanism or server and is called through the control interface or button on the breast pump.

[0695] The breast pump data storage mechanism can be various memories, which can be arranged in the host of the breast pump.

[0699] Step 520: Generate at least one recommended breast pumping data according to the breast pumping parameter data of the multiple historical breast pumping periods or the breast pumping parameter data in the multiple preset breast pumping time periods, and each recommended breast pumping data corresponds to breast pumping parameters in a callable breast pumping period or breast pumping time period.

[0700] For details, please refer to the above description, which will not be repeated here.

[0701] Step 530: Receive a recommended breast pumping data trigger signal.

[0702] In a possible implementation, the step 530 comprises receiving a recommended pumping data trigger signal generated when the recommended pumping data trigger module in the breast pump is triggered.

[0703] The recommended pumping data trigger module in the breast pump can be a virtual space displayed on a display screen on the host, or an entity control, such as a key, a button, a switch, or the like, provided on the host or the milk storage container.

[0704] In another possible implementation, the step 530 comprises receiving a recommended pumping data trigger signal sent by an electronic device in communication with the breast pump.

[0705] The step 540 comprises controlling the breast pump to work according to the recommended pumping data upon receiving the recommended pumping data trigger signal.

[0706] In the above embodiments, the user can be allowed to autonomously select whether to work according to the recommended pumping data.
