[0003] The present disclosure relates to the technical field of personal care equipment, and in particular to a sensor, a consumables output control device and method, and an intelligent personal care terminal. Background Art

[0004] For existing smart personal care devices with automatic consumable dispensing functions, dispensing too much consumables can not only lead to waste but also potentially harm the user's health. For example, using an electric toothbrush can lead to oral health problems due to excessive toothpaste use, and even fluoride in the toothpaste can cause fluorosis and dental fluorosis. For example, using skincare devices that automatically dispense skincare products should also be avoided to prevent excess nutrients that can cause fat particles and damage the skin barrier due to over-cleansing.

[0005] Because consumables contain residual air during filling, and air can accumulate in the consumables lines after first use or cleaning of smart personal care terminals, the amount of consumables ejected by the smart personal care terminals can vary significantly. However, it is currently impossible to accurately detect the presence of air in the consumables lines. Summary of the Invention

[0071] To make the technical problems, technical solutions, and advantages to be solved by the present disclosure more clear, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments. In the following description, specific details such as specific configurations and components are provided only to help fully understand the embodiments of the present disclosure. Therefore, it should be clear to those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. In addition, for the sake of clarity and brevity, descriptions of known functions and configurations have been omitted.

[0072] It should be understood that references throughout this specification to "one embodiment" or "an embodiment" mean that a particular feature, structure, or characteristic associated with the embodiment is included in at least one embodiment of the present disclosure. Therefore, the appearances of "in one embodiment" or "in an embodiment" throughout this specification do not necessarily refer to the same embodiment. Furthermore, these particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0073] The present disclosure addresses the problem in the prior art of being unable to accurately detect whether there is air in consumables pipelines, and provides a sensor, a consumables output control device, a method, and an intelligent personal care terminal.

[0074] As shown in FIG1 to FIG3 , an embodiment of the present disclosure provides a sensor, including:

[0075] A first metal part 1, a second metal part 2, and an insulating part 3 that wraps and connects the first metal part 1 and the second metal part 2, with a first gap set between the first metal part 1 and the second metal part 2; the insulating part 3, the first metal part 1, and the second metal part 2 are hollow and connected inside to form a first hollow structure A; wherein, when different media pass through the first hollow structure, the electrical parameters between the two ends of the first metal part and the second metal part are different.

[0076] Optionally, the electrical parameter between the first metal member 1 and the second metal member 2 includes a voltage value, and the voltage value is determined according to the impedance and / or capacitive reactance of the sensor.

[0077] Optionally, the insulating part 3 includes: a mounting portion 32 and a connecting portion 33; the mounting portion 32 wraps the first metal part 1 and the second metal part 2, and the connecting portion 33 separates the first metal part 1 and the second metal part 2, so that the first metal part 1 and the second metal part 2 remain in a non-contact state.

[0078] Optionally, the first metal member 1 and the second metal member 2 are arranged at both ends of the insulating member 3 .

[0079] Optionally, the insulating member 3 is made of plastic or rubber.

[0080] The sensor of the embodiment of the present disclosure, through the first metal part and the second metal part with a first gap between them, and the insulating part that wraps and connects the first metal part and the second metal part, can judge the medium passing through the interior of the sensor by the different values ​​of the electrical parameters between the ends of the first metal part and the second metal part, such as the voltage value obtained by converting the impedance and / or capacitive reactance. Therefore, when applied to a smart personal care terminal, it is possible to judge the passage of consumables in the sensor by the change of the electrical parameters between the ends of the first metal part and the second metal part, thereby judging whether there is air passing through the consumables pipeline during the current consumables output cycle. This solves the problem in the prior art of being unable to accurately detect whether there is air in the consumables pipeline.

[0081] Optionally, a first protrusion 31 is provided on the insulating part 3; the first metal part 1 and the second metal part 2 are respectively connected with corresponding wires B, and the wires B pass through the insulating part 3 and are led out from the first protrusion 31, so that the sensor is connected to the external circuit through the wires B.

[0082] Specifically, in this embodiment, two wires B are respectively wound around corresponding metal parts and connected to the corresponding metal parts by welding. The two wires B are respectively led out from the first protrusions 31 and connected to the external control circuit.

[0083] Optionally, the height of the first protrusion 31 is set to be greater than 1 mm to prevent the wire from breaking.

[0084] The sensor of the embodiment of the present disclosure connects the wire to the first metal part and the second metal part by welding, which can avoid the wire and the first metal part and the second metal part from being in virtual connection; by providing the first protrusion on the insulating part, protection can be provided at the lead-out position of the wire, avoiding the wire from breaking at the connection between the first metal part and the second metal part.

[0085] Optionally, anti-slip bosses C are provided at both ends of the first metal member 1 and the second metal member 2 .

[0086] Optionally, the first metal part 1 and the second metal part 2 are respectively connected to one of the consumables transmission tube, the consumables transmission pump and the output end of the smart personal care terminal through the anti-slip boss C.

[0087] In one embodiment of the present disclosure, the output end of the smart personal care terminal, the first metal part, the second metal part, the consumable material transmission tube, and the consumable material transmission pump are connected in sequence.

[0088] In another embodiment of the present disclosure, the output end of the smart personal care terminal, the consumable material transmission tube, the first metal part, the second metal part and the consumable material transmission pump are connected in sequence.

[0089] It should be noted that if the output end of the smart personal care terminal is connected to the first metal part or the second metal part, the connection between the output end and the first metal part or the second metal part is an insulating material; if the consumable transfer pump is connected to the second metal part and the first metal part or the second metal part, the connection between the consumable transfer pump and the first metal part or the second metal part is an insulating material.

[0090] The sensor of the embodiment of the present disclosure can make the connection between the first metal part, the second metal part and other components more stable and firm by providing the anti-drop boss, thereby preventing them from falling off after long-term use.

[0091] As shown in FIG4 , an embodiment of the present disclosure provides a consumables output control device, comprising: a consumables pipeline and a control circuit;

[0092] The consumable pipeline includes: a consumable transmission tube and the sensor as described above; the consumable transmission tube is provided with a second hollow structure, and the second hollow structure is connected to the first hollow structure inside the sensor; the control circuit is connected to the sensor through a wire, and is used to determine the consumable passage situation in the sensor based on the electrical parameters detected at both ends of the sensor to obtain the detection result.

[0093] It should be noted that when different types of media (such as consumables and air) pass through the sensor, the impedance and / or capacitive reactance at both ends of the sensor are different, and the detected voltage values ​​are different.

[0094] The consumables output control device of the disclosed embodiment, through the control circuit connected to the sensor, can detect the voltage across the sensor, thereby determining the passage of consumables within the sensor. The disclosed embodiment directly detects the passage of consumables within the sensor, avoiding external interference factors and determining whether air is passing through the consumables pipeline during the current consumables output cycle. This solves the problem of the prior art in being unable to accurately detect the presence of air in the consumables pipeline.

[0095] Optionally, the consumables output control device further includes:

[0096] A consumables transfer pump is connected to the consumables pipeline and is used to pump consumables into the consumables pipeline; the control circuit is electrically connected to the consumables transfer pump and is used to send an instruction to adjust the consumables output cycle to the consumables transfer pump based on the detection result.

[0097] The consumables output control device of the disclosed embodiment uses the consumables flow rate within the sensor as determined by the control circuit to determine whether air is passing through the consumables pipeline during the current consumables output cycle. Based on the air flow rate within the consumables pipeline, the device sends an instruction to the consumables transfer pump to adjust the consumables output cycle. The disclosed solution can adjust the consumables output cycle when air is passing through the consumables pipeline, thereby precisely controlling the output volume of consumables.

[0098] Optionally, the consumable material transfer tube includes:

[0099] A first consumable material transmission tube 4 and a second consumable material transmission tube 5; one end of the first consumable material transmission tube 4 is connected to the first metal part 1, and the other end is connected to the consumable material transmission pump; one end of the second consumable material transmission tube 5 is connected to the second metal part 2, and the other end is connected to the consumable material output end.

[0100] In one embodiment of the present disclosure, the consumable material transmission tube may have one section, two sections, or multiple sections, and the number of the sensors may be one or more, which is not limited by the present disclosure.

[0101] In the case where the consumable material transfer tube has only one section, the structure of the consumable material transfer device may be: the consumable material transfer pump, the consumable material transfer tube, the sensor and the consumable material output end are connected in sequence; or, the consumable material transfer pump, the sensor, the consumable material transfer tube and the consumable material output end are connected in sequence; in the case where the consumable material transfer tube includes a first consumable material transfer tube and a second consumable material transfer tube: the consumable material transfer pump, the first consumable material transfer tube, the sensor, the consumable material output end of the second consumable material transfer tube are connected in sequence; or, the consumable material transfer pump, the second consumable material transfer tube, the sensor, the consumable material output end of the first consumable material transfer tube are connected in sequence.

[0102] It should be noted that the consumables transmission tube is made of insulating material; when the consumables transmission tube has only one section, the consumables transmission pump connected to the sensor or the connection part of the consumables output end is made of insulating material.

[0103] The consumables output control device of the embodiment of the present disclosure can avoid the problem of the sensor being easily disconnected from other components of the consumables output control device by arranging the sensor between the first consumables transmission tube and the second consumables transmission tube.

[0104] The working principle of the consumables output control device of the embodiment of the present disclosure is as follows:

[0105] The first metal part and the second metal part are the anode and cathode respectively. The entire sensor constitutes a simulated capacitor and resistor. When the flow passes through the second hollow structure and comes into contact with the cathode and anode, the sensor will exhibit both resistance and capacitance. By detecting the changes in the electrical parameters of the sensor respectively, it can be determined whether it is consumables or air flowing through the second hollow structure.

[0106] Specifically, due to the gap between the first and second metal parts, when no consumable material passes through the second hollow structure of the sensor, the first and second metal parts are not connected, and the sensor is open circuited. At this time, the sensor's resistance can be detected as infinite and the capacitive reactance is minimal. When consumable material passes through the second hollow structure of the sensor, the first and second metal parts are connected, and the sensor is open circuited, with low resistance. Therefore, the presence of fluid passing through the sensor can be determined by detecting whether the sensor circuit is conductive.

[0107] Specifically, when consumables pass through, the inside of the sensor becomes a passage, and at this time it can be determined that consumables pass through the sensor. However, due to the viscosity of the consumables, when only small bubbles exist, the internal circuit of the sensor will also be turned on. Therefore, it is necessary to further detect changes in the electrical parameters of the sensor, such as changes in impedance and capacitive reactance, to determine whether there are bubbles in the transmitted consumables.

[0108] When only consumables pass through the consumable transmission tube, the sensor's impedance is detected to be small and its capacitive reactance is large. When consumables and air pass through the consumable transmission tube at the same time, the sensor's impedance increases and its capacitive reactance decreases compared to the state where only consumables pass through the consumable transmission tube.

[0109] Therefore, when it is determined that there are only consumables in the consumable transfer tube, time compensation is not performed on the consumable transfer cycle; when it is determined that the consumables in the consumable transfer tube are mixed with bubbles, time compensation is performed on the consumable transfer cycle to ensure that the target amount of consumables can be output.

[0110] It should be noted that different types or models of consumables have different viscosities, and when different consumables flow through the sensor, the capacitive reactance and impedance properties exhibited are also different.

[0111] In one embodiment of the present disclosure, when the viscosity of the consumable material passing through is lower than a preset value (e.g., 1000cP), only a trace amount of the consumable material will remain after flowing through the sensor. Most of the time, the remaining consumable material will not cross the anode (e.g., the first metal part) and cathode (e.g., the second metal part) of the sensor, and the impedance of the sensor will be infinite, remaining in an open circuit state. When the consumable material flows through, the conductive ions generated by the consumable material after ionization will form a path between the anode and cathode, and the current path will be quickly established. Based on the characteristic that consumable material with a viscosity lower than 1000cP will not remain on the pipe wall, direct current can be used directly for detection, and the impedance characteristics of the fluid in the pipe are the main influencing factors at this time.

[0112] In one embodiment of the present disclosure, when the viscosity of the consumable passing through is higher than a preset value (e.g., 1000 cP), a large amount of consumable residue will remain after passing through the sensor. At this time, the anode and cathode are not completely disconnected, and the conductive ions in the consumable will form a path between the two electrodes. When the consumable has not yet flowed through the sensor, there is only air and an insulating plastic pipe (the insulating member) between the two electrodes, and the resistance is infinite at this time. When the pipe is filled with consumables, the entire sensor exhibits both capacitive and resistive properties. If direct current is still used to power on the sensor before it works, the voltage obtained by the digital-to-analog converter (the detection module in the first detection circuit) will be a curve showing a Log function with an initial value not zero. The input voltage of the digital-to-analog converter will increase rapidly with time, and finally approach a flat state.

[0113] In terms of sensor stability and application, using DC power continuously feeds the sensor to maintain a near-stable voltage input to the DAC. However, this constant supply of DC power to the sensor creates an electrolytic reaction for the consumables, as shown in Figure 5. The continuous flow of DC power to the anode and cathode oxidizes and reduces the conductive ions in the consumables, forming oxides on the anode surface that attract precipitates to the sensor surface, while the cathode consumes. Consequently, the sensor's lifespan is significantly reduced when DC power is continuously applied. Furthermore, the anode is passivated by precipitates adsorbed onto the electrode surface, ultimately reducing the accuracy of the measured value over time. Furthermore, due to the high viscosity of the liquid being measured, liquid will remain on the sensor surface when air enters the sensor, still satisfying the conditions for the electrolytic reaction. Therefore, using DC power is an extremely risky and costly solution when the viscosity of the consumables passing through is higher than the preset value.

[0114] Optionally, for consumables with a viscosity less than a preset value, direct current is used to detect the sensor; for consumables with a viscosity greater than the preset value, alternating current is used to detect the sensor.

[0115] In the embodiment of this aspect, different circuit structures are used to implement direct current and alternating current for the sensor detection.

[0116] Optionally, when the viscosity of the consumable material is less than a preset value, the control circuit includes: a first detection circuit and a first control processing module connected to the first detection circuit; the first detection circuit includes: a first relay S0 and a first voltage-dividing resistor R1 connected in series, and a first detection module; the sensor is connected in series in the first detection circuit;

[0117] Among them, when the first relay is closed, the first detection module determines the detection result including the passage of consumables in the sensor based on the detected voltage value of the sensor, and sends the detection result to the first control processing module, so that the first control processing module sends an instruction to adjust the consumable output cycle to the consumable transfer pump based on the detection result.

[0118] Optionally, a direct current is passed through the first detection circuit to measure a first resistance value across the sensor through the first detection circuit;

[0119] A voltage value corresponding to the first resistance value is determined by an analog-to-digital converter according to the first resistance value.

[0120] In one embodiment of the present disclosure, direct current is applied to the sensor via the first detection circuit;

[0121] The collected first resistance value is converted into a voltage value by the first detection module (including an analog-to-digital converter), and the voltage value is sent to the first control processing module, so that the first control processing module determines whether air passes through the sensor based on the voltage value.

[0122] According to the voltage value, it is judged whether there is air passing through the sensor, and the judgment result is sent to the first control processing module; specifically, as shown in Figure 6, before the consumables transfer pump is running, the power supply of the sensor detection circuit is turned on, and a 3.3V DC voltage is passed (this voltage is a safe voltage for the normal operation of the sensor, and the voltage range can be 1.0V to 50V), R1 is the first voltage divider resistor, and before the consumables enter the sensor, the sensor resistance value R s Infinity, the entire circuit is in an open circuit state, and the voltage V collected by the analog-to-digital converter is c is the power supply voltage V s When the consumable material flows through the sensor, the equivalent resistance of the sensor is R m , the resistance value of the voltage divider resistor is R0. According to Ohm's law, the voltage value collected by the digital-to-analog converter is: V c =(V s *R m ) / (R m +R0); wherein R0 = the resistance value of R1; the analog-to-digital converter converts the voltage analog quantity into a voltage digital quantity and sends the voltage digital quantity to the first control processing module; the processor determines whether there is liquid in the sensor based on the difference in the voltage digital quantity; when the sensor does not need to be detected, the power supply voltage of the sensor is turned off to save energy.

[0123] It is worth mentioning that the sensor shown in FIG6 is connected to the first relay of the detection circuit, and the other end is grounded;

[0124] The connection position of the sensor in the control circuit may also include: the sensor is connected between the first voltage-dividing resistor of the detection circuit and the first relay, and one end of the first relay is grounded; or the sensor is connected between the first voltage-dividing resistor and the power supply, and one end of the first relay is grounded.

[0125] Optionally, when the viscosity of the consumable material is greater than a preset value, the control circuit includes:

[0126] a second detection circuit and a second control processing module connected to the second detection circuit;

[0127] The second detection circuit includes: a second voltage-dividing resistor R2 and a second detection module, a second relay S1, and a third relay S2 connected in series; the second relay S1 and the third relay S2 are both single-pole three-throw relays; a first end of the second relay S1 is connected to one end of the sensor, and a first end of the third relay S2 is connected to the other end of the sensor; a second end of the second relay S1 is connected to the first end of the second voltage-dividing resistor, and a third end of the second relay S1 is grounded; a second end of the third relay S2 is connected to the first end of the second voltage-dividing resistor, and a third end of the third relay S2 is grounded; and a second end of the second voltage-dividing resistor R2 is connected to a power supply;

[0128] In which, when the first end of the second relay S1 switches between the second end and the third end at a preset frequency, and the first end of the third relay S2 switches between the second end and the third end at a preset frequency, the second detection module determines the detection result including the passing of the consumables in the sensor based on the detected voltage value of the sensor, and sends the detection result to the second control processing module, so that the second control processing module sends an instruction to the consumable transfer pump to adjust the duration of the consumable output cycle based on the detection result.

[0129] Optionally, by passing alternating current through the second detection circuit, the second resistance value at both ends of the sensor is measured by the second detection circuit; and based on the second resistance value, the voltage value corresponding to the second resistance value is determined by the second detection circuit (including an analog-to-digital converter).

[0130] In one embodiment of the present disclosure, an alternating current is applied to the sensor via the second detection circuit;

[0131] The collected second resistance value is converted into a voltage value by the analog-to-digital converter, and the voltage value is sent to the second control processing module, so that the second control processing module determines whether air passes through the sensor according to the voltage value.

[0132] It is determined whether air passes through the sensor according to the voltage value, and the determination result is sent to the second control processing module.

[0133] Specifically, as shown in FIG7 , two single-pole triple-throw switches (the second relay and the third relay) are used to apply alternating current to the sensor through a direct current power supply:

[0134] The second control processing module controls the second relay S1 and the third relay S2 to be on the same throwing point through switching. When they are controlled at the top throwing point (the first end and the second end are connected), the direction of the current in the sensor is recorded as I+; when they are controlled at the bottom throwing point (the first end and the third end are connected), the current direction is opposite and recorded as I-; if they are placed at the middle throwing point, the entire circuit is disconnected and no current flows through the sensor. During the sensor detection period, the second control processing module controls the second relay S1 and the third relay S2 to switch between different throwing points, thereby generating an AC signal with a frequency of f1 (f1 can range from 5Hz to 100kHz, the specific frequency is related to the sensor structure itself) on the sensor. Due to the characteristic of capacitors that block DC and pass AC, the sensor's impedance characteristic is the main influencing factor at this time. The capacitive reactance will be slowed down by the AC, which greatly shortens the level establishment time on the sensor, allowing it to more accurately, efficiently, and quickly detect whether air is passing through the sensor in a short time.

[0135] Whenever the first terminal of the second relay or the third relay is connected to the second terminal or the third terminal, when the consumable flows through the sensor, the equivalent resistance value of the sensor is R m , the resistance value of the voltage divider resistor is R0. According to Ohm's law, the voltage value collected by the digital-to-analog converter is: V c =(V s *R m ) / (R m + R0); where R0 = the resistance value of R2.

[0136] As shown in FIG8 , the control circuit includes:

[0137] a third detection circuit and a third control processing module connected to the third detection circuit;

[0138] The third detection circuit includes: a third voltage-dividing resistor R3 and a third detection module, a fourth relay S3, and a fifth relay S4 connected in series; the fourth relay S3 and the fifth relay S4 are both single-pole three-throw relays; a first end of the fourth relay S3 is connected to one end of the sensor, and a first end of the fifth relay S4 is connected to the other end of the sensor; a second end of the fourth relay S3 is connected to a power supply, and a third end of the fourth relay S3 is connected to the first end of the third voltage-dividing resistor; a second end of the fifth relay S4 is connected to the power supply, and a third end of the fifth relay S4 is connected to the first end of the third voltage-dividing resistor; and a second end of the third voltage-dividing resistor is grounded;

[0139] Among them, when the first end of the fourth relay S3 switches between the second end and the third end at a preset frequency, and the first end of the fifth relay S4 switches between the second end and the third end at a preset frequency, the third detection module determines the detection result including the passing of the consumables in the sensor based on the detected voltage value of the sensor, and sends the detection result to the third control processing module, so that the third control processing module sends an instruction to the consumable transfer pump to adjust the duration of the consumable output cycle based on the detection result.

[0140] It should be noted that the connection method between the sensor and the control circuit shown in FIG8 is a variation of the connection method shown in FIG7 .

[0141] As shown in FIG9 , an embodiment of the present disclosure further provides a consumables output control method, which is applied to the consumables output control device described above, and includes the following steps:

[0142] Step 901: acquiring in real time a voltage value collected by the control circuit during a consumables output cycle of the consumables output control device; the voltage value is determined according to the impedance and / or capacitive reactance of the sensor;

[0143] Step 902: determining, based on the voltage value, whether the consumables have passed through the sensor during the consumables output cycle;

[0144] Step 903 : When it is determined that air passes through the sensor during the consumables output cycle, the duration of the consumables output cycle is adjusted.

[0145] The consumables output control method of the disclosed embodiment uses the voltage value collected by the control circuit to determine the consumables passing through the sensor during the consumables output cycle. This method can extend the consumables transmission cycle in the event of bubbles in the consumables transmission process, thereby ensuring the stability of the consumables output. The disclosed embodiment solves the problem of inconsistent and unstable consumables output in smart personal care terminals due to bubbles in the consumables filling process or air in the consumables transmission pipeline.

[0146] It should be noted that the smart personal care terminal can be a smart toothbrush, a beauty instrument or a skin care instrument, and the consumables can be toothpaste or skin care products; the smart personal care terminal includes a consumable bottle (such as a toothpaste bottle), a consumable transfer pump, a consumable pipeline (including the consumable transfer tube and the sensor) and a consumable output end (such as a toothbrush head or a skin care product output head); the two interfaces of the consumable transfer pump are respectively connected to the consumable bottle and the consumable pipeline; wherein, the consumables are transferred from the consumable bottle to the consumable output end through the consumable pipeline by the consumable transfer pump.

[0147] Optionally, the consumables transfer pump is one of an air pump, a peristaltic pump, a gear pump, a screw pump and a rotor pump.

[0148] In a preferred embodiment of the present disclosure, the consumable material transfer pump is a peristaltic pump.

[0149] Optionally, when the viscosity of the consumable material is lower than a preset value, the real-time acquisition of the voltage value collected by the control circuit includes:

[0150] Controlling the first relay to close; and determining the voltage value according to the collected impedance of the sensor.

[0151] In the consumables output control method of the embodiment of the present disclosure, when the viscosity of the consumables is lower than a preset value, direct current is applied to the sensor through the structure shown in FIG6 .

[0152] Optionally, when the viscosity of the consumable material is higher than a preset value, the real-time acquisition of the voltage value collected by the control circuit includes:

[0153] Controlling the first end of the second relay to switch between the second end and the third end at a preset frequency, and controlling the first end of the third relay to switch between the second end and the third end at a preset frequency; obtaining a first voltage collected when the first end of the second relay is connected to the second end and the first end of the third relay is connected to the second end; obtaining a second voltage collected when the first end of the second relay is connected to the third end and the first end of the third relay is connected to the third end;

[0154] The voltage value is determined according to the first voltage and the second voltage.

[0155] Optionally, determining the voltage value according to the first voltage and the second voltage includes:

[0156] A median value between the first voltage and the second voltage is determined as the voltage value.

[0157] The consumable output control method of the embodiment of the present disclosure, when the viscosity of the consumable is higher than a preset value, controls the second relay and the third relay to switch between different throws through the structure shown in Figure 7 or Figure 8, and applies direct current to the sensor.

[0158] The consumables output control method of the disclosed embodiment can accurately detect whether air passes through the sensor by using different control circuits for consumables of different viscosities; and by using alternating current for the sensors corresponding to consumables of different viscosities, the life of the sensors can be increased and the accuracy of detection can be ensured.

[0159] Optionally, judging, based on the voltage value, whether the consumables have passed through the sensor during the consumables output cycle includes:

[0160] If the voltage value in the first time period within the consumable output cycle is less than the first preset threshold value, it is determined that only consumables pass through the sensor during the consumable output cycle; if the voltage value in the second time period within the consumable output cycle is greater than the first preset threshold value, it is determined that air passes through the sensor during the consumable output cycle; wherein the sum of the first time period and the second time period is equal to the consumable output cycle; the first preset threshold value is obtained from the database of the consumable output control device according to the type of the consumable.

[0161] It should be noted that the first preset value is determined through pre-testing:

[0162] When the viscosity of the consumable is less than a preset value, the sensor is detected by direct current, and the average value of the multiple groups of voltage values ​​collected by the control circuit is calculated as the critical value of the consumable (the first preset threshold value). When the voltage value is greater than the critical value, it is determined that air is passing through the sensor; when the viscosity of the consumable is greater than the preset value, the sensor is detected by alternating current. During the switching of the throws of the second relay and the third relay, two voltage values ​​are collected by the analog-to-digital converter, namely Vd1 and Vd2. The median value of the multiple groups of Vd1 and Vd2 is calculated as the critical value of the consumable (the first preset threshold value). When the voltage value is greater than the critical value, it is determined that air is passing through the sensor.

[0163] In the embodiment of the present disclosure, the median values ​​of the multiple groups of Vd1 and Vd2 are determined by the following method:

[0164] Draw a median line of each group of Vd1 and Vd2; and determine the first preset threshold value according to the median line.

[0165] Optionally, the method further includes:

[0166] If the voltage value in the third time period of the consumables output cycle is greater than a second preset threshold, it is determined that only air passes through the sensor during the consumables output cycle;

[0167] The second preset threshold is greater than the first preset threshold.

[0168] In the embodiment of the present disclosure, the fact that only air passes through the sensor can be understood as the smart personal care terminal having not been used. Therefore, the smart personal care terminal can be verified as a new device according to the second preset threshold.

[0169] It should be noted that the critical value NumX when only consumables pass through the sensor is less than the critical value NumZ when only air is in the sensor; and the critical value NumY when there are both consumables and air in the sensor is greater than NumX and less than NumZ; different consumables correspond to different NumX, NumY and NumZ; the first preset threshold and the second preset threshold are determined based on NumX, NumY and NumZ.

[0170] Optionally, the first preset threshold may be a value greater than or equal to NumY and less than NumZ, and the second preset threshold may be a value greater than NumZ.

[0171] In one embodiment of the present disclosure, the first preset threshold may be an average value of NumY and NumZ.

[0172] In one embodiment of the present disclosure, the first preset threshold or the second preset threshold corresponding to multiple consumables is saved in the smart personal care terminal through a database; when installing consumables in the smart personal care terminal, the first preset threshold or the second preset threshold corresponding to the consumable saved in the database can be selected.

[0173] In one embodiment of the present disclosure, if the first preset threshold and the second preset threshold corresponding to the consumables used are not in the database, the first preset threshold and the second preset threshold are saved in the database.

[0174] The consumables output control method of the disclosed embodiment can detect whether there are bubbles in the consumables transmission tube during the consumables output process by determining the first preset threshold value and the second preset threshold value, thereby adjusting the duration of the consumables output cycle and achieving precise control of the consumables output amount.

[0175] Optionally, adjusting the duration of the consumables output cycle includes:

[0176] Determine a first moment at the start of the second time period and a second moment at the end of the second time period; determine a first duration, which is the duration required for the consumable to move from the input end of the consumable transfer pump to the consumable output end; determine a third moment at the start of the consumable output cycle and a fourth moment at the end of the consumable output cycle; determine a compensation duration for the consumable output cycle based on the first moment, the second moment, the third moment, the fourth moment and the first duration; and adjust the duration of the consumable output cycle based on the compensation duration.

[0177] It should be noted that the first duration is determined by pre-measurement;

[0178] The consumables output cycle is a preset duration, and the consumables transmitted in each consumables output cycle are the consumables usage of the smart personal care terminal once;

[0179] First, the amount of consumables required each time is determined; then, the consumables output cycle is determined based on the amount of consumables and the flow rate of the consumables transmitted by the smart personal care terminal.

[0180] In the embodiment of the present disclosure, the flow rate of the consumables transmitted by the smart personal care terminal can be measured through testing (for example, when the entire cavity is full of consumables, the consumables are fixedly pushed out for 10S and the consumables are weighed. For example, if the weight is 5g, then the flow rate of the consumables is 0.5g / s), and then the time required for the consumables to be pushed out (i.e., the consumables output cycle) can be calculated based on the actual demand for the consumables.

[0181] The consumables output control method of the embodiment of the present disclosure determines the first moment and the second moment, the third moment at the start and the fourth moment at the end of the consumables output cycle; and based on the pre-measured first time length, determines the compensation time length required for the consumables output cycle, thereby ensuring the consistency of the amount of consumables transmitted in each consumables output cycle.

[0182] Optionally, determining the compensation duration for the consumable output cycle according to the first moment, the second moment, the third moment, the fourth moment, and the first duration includes:

[0183] Determine a fifth moment, the fifth moment being the moment after the first moment by the first duration; determine a sixth moment, the sixth moment being the moment after the second moment by the first duration; and determine a compensation duration for the consumable output cycle based on the first moment, the second moment, the third moment, the fourth moment, the first duration, the fifth moment, and the sixth moment.

[0184] In the embodiment of the present disclosure, the first moment may be understood as the moment when the bubble enters the sensor, and the second moment may be understood as the moment when the bubble leaves the sensor;

[0185] The fifth moment is the moment of the first duration after the first moment, that is, the fifth moment can be understood as the moment when bubbles begin to reach the output end of the smart personal care terminal, and the sixth moment can be understood as the moment when bubbles are completely discharged from the smart personal care terminal.

[0186] As shown in FIG10 , in one embodiment of the present disclosure, the smart personal care terminal is a smart toothbrush, and the consumable is toothpaste;

[0187] The first moment is the moment t1 when the bubbles begin to enter the sensor input end, and the second moment is the moment t2 when the bubbles are discharged from the sensor output end; the first time length is the time △t required for the consumable to be transferred from the input end of the sensor to the consumable output end D; the third moment is t3, and the fourth moment is t4; the fifth moment is the moment t5=t1+△t when the bubbles are transferred to the consumable output end D; the sixth moment is the moment t6=t2+△t when the bubbles are completely discharged from the consumable output end D.

[0188] Optionally, as shown in FIG11 , determining the compensation duration for the consumable output cycle according to the first moment, the second moment, the third moment, the fourth moment, and the first duration includes:

[0189] When the fifth moment is later than the fourth moment, the compensation duration is 0.

[0190] It should be noted that the first moment and the second moment are both within the consumable output cycle; the fifth moment t5 is later than the fourth moment t4, which can be understood as that there are bubbles within the consumable output cycle T, but after the consumable output cycle T ends, the bubbles are still in the consumable pipeline and have not reached the consumable output end of the smart personal care terminal. Therefore, there is no need to compensate for the running time of the consumable output cycle.

[0191] The consumables output control method of the disclosed embodiment can determine, based on the sequential relationship between the fifth moment and the fourth moment, whether bubbles present within the consumables output cycle reach the consumables output end of the smart personal care terminal before the end of the consumables output cycle, thereby determining the compensation duration for the consumables output cycle. The disclosed solution can calculate the actual consumables transmission time within the consumables output cycle, thereby determining whether a sufficient amount of consumables has been transmitted within the consumables output cycle, thereby ensuring the consistency and stability of the consumables transmission amount by the smart terminal.

[0192] Optionally, determining the compensation duration for the consumable output cycle according to the first moment, the second moment, the third moment, the fourth moment, and the first duration includes:

[0193] In the case that the fifth moment is earlier than the fourth moment and the sixth moment is later than or equal to the fourth moment, the compensation duration is the duration from the fifth moment to the fourth moment.

[0194] It should be noted that, as shown in FIG12 , the fifth moment t5 is earlier than the fourth moment t4, and the sixth moment t6 is later than the fourth moment t4. It can be understood that there are bubbles in the consumable output cycle T and the bubbles reach the consumable output end of the smart personal care terminal before the end of the consumable output cycle T. At the same time, at the end of the consumable output cycle T, the bubbles are not completely discharged from the consumable output end of the smart personal care terminal. Therefore, it is only necessary to compensate the consumable output cycle for the duration from the fifth moment t5 to the fourth moment t4 (the transmission duration of the bubble discharge part); at the same time, as shown in FIG13 , the fifth moment t5 is earlier than the fourth moment t4, and the sixth moment t6 is equal to the fourth moment t4. It can be understood that there are bubbles in the consumable output cycle T and the bubbles reach the consumable output end of the smart personal care terminal before the end of the consumable output cycle. At the same time, at the end of the consumable output cycle T, the bubbles are just completely discharged from the consumable output end of the smart personal care terminal. At this time, the time length from the fifth moment t5 to the fourth moment t4 is the time length from the fifth moment t5 to the sixth moment t6, which is equal to the time length from the first moment t1 to the second moment t2.

[0195] The consumables output control method of the disclosed embodiment can determine whether bubbles present during the consumables output cycle reach the consumables output terminal of the smart personal care terminal before the end of the consumables output cycle based on the sequential relationship between the fifth moment and the fourth moment; and can determine whether bubbles are completely discharged from the consumables output terminal of the smart personal care terminal at the end of the consumables output cycle based on the sequential relationship between the sixth moment and the fourth moment, thereby determining the compensation duration for the consumables output cycle. The disclosed solution can calculate the actual transmission time of consumables during the consumables output cycle, thereby determining whether a sufficient amount of consumables has been transmitted during the consumables output cycle, thereby ensuring the consistency and stability of the consumables transmission amount by the smart terminal.

[0196] Optionally, determining the compensation duration for the consumable output cycle according to the first moment, the second moment, the third moment, the fourth moment, and the first duration includes:

[0197] In the case that the fourth moment is later than the sixth moment, the compensation duration is the duration between the first moment and the second moment.

[0198] It should be noted that, as shown in Figure 14, the fourth moment t4 is later than the sixth moment t6. It can be understood that before the end of the consumable output cycle T, the bubble is completely discharged from the consumable output end of the smart personal care terminal. Therefore, the compensation time is the transmission time of the entire bubble.

[0199] The consumables output control method of the disclosed embodiment can determine whether bubbles are completely discharged from the consumables output port of the smart personal care terminal at the end of the consumables output cycle by using the sequence relationship between the sixth moment and the fourth moment, thereby determining the compensation duration for the consumables output cycle. The disclosed solution can calculate the actual consumables transmission time within the consumables output cycle, thereby determining whether a sufficient amount of consumables has been transmitted within the consumables output cycle, thereby ensuring the consistency and stability of the consumables transmission amount by the smart terminal.
