Description

Dustproof method, electronic device, and readable storage medium

Technical Field

The invention relates to the technical field of intelligent terminals, in particular to a dustproof method, electronic equipment and a readable storage medium.

Background

With the gradual development of technology of intelligent wearable electronic devices (i.e., wearable devices, such as smart watches, smart bracelets, etc.), intelligent wearable devices with blood pressure measurement functions have been developed, which also makes the blood pressure measurement devices develop towards intelligentization and wearable. At present, the intelligent wearable device with the blood pressure measurement function has the principle of blood pressure measurement generally consistent with the principle of a traditional electronic sphygmomanometer, for example, the principle of an oscillography is adopted.

As an example, referring to fig. 1, a smart watch 100 for detecting blood pressure based on the oscillometric principle may include, for example, a structure such as a watch body 101, an air bag 180, and a wristband (not shown in the drawing), wherein the air bag 180 may be attached to the inner sides of the watch body 101 and the wristband so that the watch body 101 and the wristband may press the air bag 180 against the arm when the smart watch 100 is worn on the arm. The air pump 170, the air pressure sensor 162, the micro control unit (Microcontroller Unit; MCU) (not shown in the figure) and the driving circuit connected with the MCU are arranged in the meter body 101, the air pump 170 and the air bag 101 can be communicated through the air passage conduction assembly, and the air pressure sensor 162 can be electrically connected with the MCU. When the blood pressure is measured, the MCU can control the air pump 170 to be electrified to inflate the air bag 180, so that the air bag 180 extrudes the arm; the air pressure sensor 162 may detect an air pressure difference (abbreviated as a pressure difference) in the air path conducting assembly of the communication air bag 180 and transmit the detection result to the MCU, and the MCU may determine a blood pressure value of the user based on the detected pressure value change and display the blood pressure value to the user through the display screen of the smart watch 100. The manner in which the air bag 180 is attached to the watch body 101 and the inside of the watchband may include, for example, a movable connection manner such as magnetic attraction, adhesion, and fastening, that is, the air bag 180 may be detachable. It will be appreciated that some smart wearable devices with blood pressure measurement may also be used in other modes of use than the user's blood pressure measurement mode, such as a sports mode, where the bladder 180 may be removed in order to maintain the breathability of the smart watch 100 during movement.

When the air bag 180 is detached, fine dust may pollute the air inlet 171 and the air nozzle 181, and the accumulated dust may cause blockage of the air passage guide assembly and damage to components such as the air pressure sensor 162/the air pump 170. Even if the air bag is removed, the dust-proof protection can be performed by installing the dust-proof cover, dust can still pollute the air port 171 and the air tap 181 of the watch body when the air bag is removed and the gap for installing the dust-proof cover is still left between the user and the air bag, and the user often forgets to install the dust-proof cover or can not install the dust-proof cover in time when the air bag 180 is removed. Therefore, a dust-proof solution is needed to solve these problems.

That is, when the electronic device (e.g., a smart watch) detects that the second portion (e.g., an air bag) or the third portion (e.g., a dust cover) is detached from the first portion (e.g., a watch body), the air charging device may be controlled to be started with a preset first operation parameter and perform air blowing and dust prevention.

That is, the electronic device (e.g., a smart watch) may preset a single-stage threshold for the air pressure difference value at two ends of the air duct, where the single-stage threshold is the first pressure difference threshold. When the air pressure difference value at the two ends of the air duct exceeds the threshold value, the air blowing rate is increased to clear the blockage by adjusting and controlling the working parameters (such as improving the duty ratio) of the air charging device, or prompt information is displayed through an interface to remind a user to go to an after-sale service place to clear the blockage manually, and the like. When the difference value of the air pressure at the two ends of the air duct is detected not to exceed the threshold value, the air charging device can keep the first working parameter to blow and prevent dust normally.

When the air pressure difference value of the two ends of the air duct is detected to be between the second pressure difference threshold value and the third pressure difference threshold value, the working parameters (such as the duty ratio is increased) of the air charging device are adjusted and controlled to increase the air blowing rate for blocking removal; when the air pressure difference value at the two ends of the air duct exceeds a third pressure difference threshold value, a prompt message can be displayed through an interface to remind a user to go to an after-sales service place for manual blockage removal.

The second prompting interface displayed by the electronic device for prompting the user to go to the after-sales service for manual blockage removal may refer to an interface shown in fig. 11 in the following embodiments, which is not described herein. Therefore, blocking removal measures can be adopted for blocking differences of different degrees in the air guide channel or at the air charging port, the blocking removal efficiency is improved, and the air charging performance of the air charging device in the electronic equipment is convenient to maintain and stable.

Detailed Description

In order to solve the problem that dust cannot be prevented from polluting an air tap of an air bag and an inflation port (namely a surface air port) of some wearable electronic equipment with a blood pressure measurement function at present, the embodiment of the application provides a dustproof method. Specifically, whether the air bag or the dust cover is detached or not is recognized, whether the air pump blows to the air charging port or not is determined, and at the moment, the wearing equipment can remind a user to install the dust cover or the air bag as soon as possible through the display interface so as to prevent the air charging port from being polluted by dust. It can be appreciated that in order to avoid that the wearable device is frequently in the active dustproof state, the method can solve the problem that the energy consumption of the wearable device is possibly increased due to the fact that the wearable device is frequently in the active dustproof state by setting a starting time interval threshold value or an ending time interval threshold value of two adjacent active dustproof states.

In addition, the method can detect whether the air inflation port and the air channel conduction assembly communicating the air pump and the air bag are blocked due to dust pollution in a state of detaching the air bag or the dust cover, and can take blocking removal measures corresponding to different degrees of air channel blocking according to the detected air pressure difference value, for example, the blocking removal measures can comprise clearing the blocking in the air channel by improving the duty ratio of the work of the air pump and increasing the blowing speed, or guiding a user to after-sale service to clear through prompt information and the like.

Therefore, the dustproof scheme provided by the embodiment of the application is beneficial to guaranteeing normal use of the blood pressure measurement function of the wearable device, and also beneficial to prolonging the service life of the wearable device, so that the use experience of a user is improved.

By way of example, the wearable device with blood pressure measurement function in the embodiments of the present application may include, but is not limited to, a smart watch, a smart bracelet, smart glasses, a smart foot ring, a smart necklace, an augmented reality (augmented reality, AR) device, a Virtual Reality (VR) device, etc., and the specific form of the wearable device is not particularly limited in this application. The following description will proceed with reference to the smart watch 100 with blood pressure measurement function as an example.

Fig. 2 illustrates an interface diagram of the smart watch 100 prompting a user to enter an active dust-proof state, in accordance with an embodiment of the present application.

As shown in fig. 2, when the air bag or the dust cover, which is originally connected to the watch body of the smart watch 100, is detached from the watch body of the smart watch 100, the smart watch 100 starts the air pump to enter the active dust-proof state, and at this time, the reminding interface 210 may be displayed on the screen of the smart watch 100. The prompt interface 210 includes a prompt message box 211, and the prompt message displayed in the message prompt box 211 may be, for example, "the active dustproof function is turned on, please install an air bag or a dustproof cover in time, so as to avoid dust pollution", so as to prompt the user that the smart watch 100 is in the active dustproof state at this time. In other embodiments, the shape of the information prompt box 211 may be different from that shown in fig. 2, and the content of the prompt information displayed by the information prompt box 211 may be other content for prompting the smart watch 100 to start the active dustproof function, which is not limited herein.

As further shown in fig. 2, the alert interface 210 displayed on the smart watch 100 further includes a close button 212, where the close button 212 may be displayed below the prompt information frame 211, and the close button 212 may display, for example, a "close active dust-proof" word, and the user may click on the close button 212 on the alert interface 210 displayed on the smart watch 100 to make the smart watch 100 exit the active dust-proof state. Referring to the schematic working principle of the smart watch 100 shown in fig. 1, the result corresponding to exiting the active dustproof state may be, for example, that the air pump 170 in the watch body 101 of the smart watch 100 stops working, and no air is blown to the air charging port, which is not limited herein.

Before describing the dust-proof method provided in the embodiment of the present application, first, the structure of the smart watch 100 provided in the embodiment of the present application is described. Fig. 3 shows a block schematic diagram of a smart watch 100, according to an embodiment of the present application.

As shown in fig. 3, the smart watch 100 includes a Micro-Controller Unit (MCU) 110, a storage Unit 120 connected to the Micro-Controller Unit 110, a display 130, an interaction Unit 140, a wireless Unit 150, a photoplethysmography (photo plethysmography, PPG) sensor 161, an air pressure sensor 162, a hall sensor 163, and an air pump 170, the smart watch 100 may further be externally connected with an air bag 180, and the air pump 170 is communicated with the air bag 180 through an air path conduction assembly. Among other things, the airbag 180 may include an airbag air tap 181, a magnet 182 that can be brought into close proximity with the hall sensor 163 of the smartwatch 100 to create a hall effect, and the like.

It should be understood that the structure illustrated in the embodiments of the present invention does not constitute a specific limitation on the smart watch 100. In other embodiments of the present application, the smart watch 100 may include more or fewer components than shown, or certain components may be combined, or certain components may be split, or different arrangements of components. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

The micro control unit 110 is used for performing system scheduling, and can be used for controlling the working states of a display screen, a touch screen, an air pump 170 and the like, and also can be used for controlling a sensor to collect corresponding sensor data, performing operation processing on the corresponding sensor data and the like. The sensor may be a PPG sensor 161, an air pressure sensor 162, a hall sensor 163, or other sensor, among others. For example, in some embodiments of the present application, when the air bag 180 is in the detached state, the micro control unit 110 may control the air pump 170 to work for active dust prevention, and collect the air pressure difference in the air channel conducting assembly connected to the air pump 170 by using the air pressure sensor 162, so as to determine whether the air channel conducting assembly and the inflation inlet 171 are blocked. In other embodiments, the micro control unit 110 may further analyze the air pressure difference acquired by the air pressure sensor 162 after the air pump 170 inflates the air bag 180 to obtain the blood pressure value of the user when the user measures the blood pressure.

The storage unit 120 is used to store software programs and data, and the micro control unit 110 performs various functional applications and data processing of the smart watch 100 by running the software programs and data stored in the storage unit. In some embodiments of the present application, the storage unit 120 may store data collected by the PPG sensor 142, the ACC sensor 143, and the temperature sensor 141.

The display 130 may be used to display information input by a user or information prompted to the user, various function menus of the smart watch, and the like. Further, the touch panel may cover the display screen 130 to form a touch screen, so that touch operations of the user on the smart watch 100 can be collected, for example, in the embodiment of the present application, the user turns off the active dustproof function by clicking a corresponding button on the touch screen of the smart watch 100. It will be appreciated that when the touch panel detects a touch operation by a user on or near the touch panel, the touch panel may determine the type of touch event and communicate the touch event to the micro-control unit 110, and the micro-control unit 110 may then provide a corresponding visual output on the display screen based on the type of touch event. For example, in the embodiment of the present application, the prompt information box 211 and the close button 212 shown in fig. 2 may be displayed on the display screen 130 of the smart watch 100, so as to improve the man-machine interaction experience between the user and the smart watch 100.

The interaction unit 140 is configured to implement man-machine interaction between the user and the smart watch 100, and interaction between other devices and the smart watch 100. The interaction unit 140 may include the above-mentioned touch screen, and may further include a microphone, a speaker, and bluetooth, a near field communication technology (near field communication, NFC) device, etc. The touch screen may implement a touch operation function of the smart watch 100 and user interaction, the microphone, the speaker, etc. may implement a voice interaction function of the smart watch 100, and the bluetooth/NFC device, etc. may implement a near field communication function of the smart watch 100.

The wireless unit 150 is used to implement the wireless communication function of the smart watch 100. For example, the smart watch 100 may perform wireless communication through an antenna, a mobile communication module, a wireless communication module, a modem processor, a baseband processor, and the like. The antenna can be used for transmitting and receiving electromagnetic wave signals, the mobile communication module can provide a solution of wireless communication including 2G/3G/4G/5G and the like applied to the smart watch 100, the mobile communication module can receive electromagnetic waves through the antenna 1, perform processes such as filtering, amplifying and the like on the received electromagnetic waves, transmit the electromagnetic waves to a modem processor for demodulation, and amplify signals modulated by the modem processor and convert the signals into electromagnetic waves to radiate through the antenna. The modem processor may include a modulator and a demodulator. The modulator is used for modulating the low-frequency baseband signal to be transmitted into a medium-high frequency signal. The demodulator is used for demodulating the received electromagnetic wave signal into a low-frequency baseband signal. The wireless communication module may provide a solution for wireless communication including wireless local area network (wireless local area networks, WLAN) (e.g., wireless fidelity (wireless fidelity, wi-Fi) network), global navigation satellite system (global navigation satellite system, GNSS), etc., as applied to the smart watch 100.

The sensor module of the smart watch 100 includes a PPG sensor 161, a barometric pressure sensor 162, a hall sensor 163, although not shown, the smart watch 100 may also include an ambient light sensor, a temperature sensor, a gyro sensor, etc. The PPG sensor 161 may be electrically connected to the micro-control unit 110 through a AFE (Active Front End) rectifying/feedback unit.

The air pump 170, when combined with the air bladder 180, the air pressure sensor 162, and the micro control unit 110, may be used to perform the blood pressure measurement function of the smart watch 100. For example, in the process of inflating the air pump 170 to the air bag 180, the air pressure difference in the air path communication component between the air pump 170 and the air bag 180 can be measured by the air pressure sensor 162, and the micro control unit 110 calculates the blood pressure value of the user based on the measured air pressure difference and a preset blood pressure algorithm. The air pump 170 may be electrically connected to the micro control unit 110 through an air pump driving circuit.

In the embodiment of the present application, when the air pump 170 is matched with the hall sensor 163 and the micro control unit 110, a function of blowing air to the air charging port 171 to prevent dust when the removal of the air bag 180 is detected, and the like can be realized. Reference is made specifically to the following detailed description, which is not repeated here.

The magnet 182 may be disposed at one end of the air tap 181 of the air bag 180, so that the smart watch 100 may identify whether the air bag 180 is detached by detecting a voltage value of the magnet 182 in a state of being close to or separated from the hall sensor 162. In other embodiments, the smart watch 100 may also identify whether the bladder 180 is detached through other structures, such as through electrode contacts, NFC, or the like.

The power supply 190 may be electrically connected to the micro control unit 110, the hall sensor 163, and the like, to supply power to the various structures in the smart watch 100. The micro control unit 110 may also implement functions of managing charging, discharging, power consumption management, etc. by operating the power management system.

It can be appreciated that the dust-proof method provided in the embodiments of the present application all needs to detect whether the air bag or the dust-proof cover is detached from the watch body. In order to facilitate understanding of the dust-proof method provided in the embodiments of the present application, the following description will first discuss, with reference to the accompanying drawings, whether the smart watch 100 detects whether the air bag or the dust-proof cover is detached from the watch body based on the principles of hall effect or the like.

Fig. 4a shows a schematic diagram of a connection structure of the smart watch 100, the airbag 180, and the dust cap 400 according to an embodiment of the present application.

As shown in fig. 4a, the smart watch 100 includes a watch body 101 and a wristband 102. An air pump 170 is arranged in the watch body 101, and an air charging port 171 of the air pump 170 is arranged on the surface of the watch body 101, so that the air pump 170 can be in sealing connection with an air bag nozzle 181 when the air bag 180 is installed, and then the air pump 180 can charge air into the air bag 180.

It will be appreciated that when the bladder 180 is mounted on the body 101 of the smart watch 100, the smart watch 100 may perform a blood pressure measurement function by controlling the air pump 170 to inflate the bladder 180. Specifically, one end of the airbag 180 having the airbag nozzle 181 may be mounted on the watch body 101 of the smart watch 100, and the other portion of the airbag 180 may be fixed on the surface of the wristband 102 on the side where the arm is attached. At this time, the air bag nozzle 181 is positioned opposite to the air inflation port 171 and is hermetically connected so that the air flow blown out by the air pump 170 can enter the air bag 180 through the air inflation port 171 and the air bag nozzle 181 when measuring the blood pressure. It will be appreciated that during the measurement of blood pressure, the air pump 170 inflates the air bladder 170, the air pressure in the air bladder 180 and on the side of the inflation port 171 will gradually increase, the air pressure difference detected by the air pressure sensor 162 will also gradually increase, and the greater air pressure in the air bladder 180 will cause the air bladder 180 to compress the artery of the user's arm. After the bladder 180 reaches a certain fullness level, the smart watch 100 may control the air pump 170 to decrease the blowing rate so that the bladder 180 remains in the current state for a certain period of time, during which the air pressure sensor 162 may detect a corresponding change in the air pressure difference due to the expansion or contraction of the blood vessel, thereby determining the blood pressure of the user based on the change. The measurement interface displayed when the smart watch 100 measures the blood pressure may refer to the measurement interface 401 shown in fig. 4b, and the smart watch 100 may measure the blood pressure of the user, which includes, for example, the diastolic pressure and the systolic pressure, and the unit of millimeter (mmHg).

When the user does not need to use the air bag 180 to measure the blood pressure, the air bag 180 can be detached, and after the air bag 180 is detached, the user can install the dust cover 400 at the inflation inlet 171 of the watch body 101 to cover the inflation inlet 171 and prevent dust from entering the inflation inlet 171 to cause blockage. Accordingly, referring to fig. 4a, a sealing structure 410 may be provided on the dust cap 400, and when the dust cap 400 is mounted on the watch body 101, the sealing structure 410 on the dust cap 400 can be hermetically connected with the inflation port 171 to cover the inflation port 171.

It will be appreciated that, in order to be able to detect the state in which the airbag 180 is detached from the case 101, that is, in the detached state, from the case 101 of the smart watch 100, referring to fig. 4a, a hall sensor 163 may be provided in the case 101 of the smart watch 100, and the hall sensor 163 may be provided near the inflation port 171. Correspondingly, a magnet 182 can be arranged at the end of the air bag 180 where the air bag nozzle 181 is located. When the air bag 180 is mounted on the watch body 101, the magnet 182 on the air bag 180 can be opposed to the position of the hall sensor 163 on the watch body 101. At this time, the magnet 182 can generate a hall effect with the hall sensor 163 to cause a voltage value at two ends of the hall sensor 163 to change, which will be described in detail with reference to a schematic circuit diagram, and will not be described herein.

Similarly, as shown with reference to fig. 4a, a magnet 420 may also be provided on the dust cap 400. When the dust cap 400 is mounted on the watch body 101, the magnet 420 on the dust cap 400 can be opposed to the position of the hall sensor 163 on the watch body 101. At this time, the magnet 420 can generate a hall effect with the hall sensor 163 to cause a voltage value change at two ends of the hall sensor 163, which will be described in detail below with reference to a schematic circuit diagram, and will not be described herein.

It will be appreciated that the magnetic force of the magnet 182 disposed on the air bag 180 and the magnetic force of the magnet 420 disposed on the dust cover 400 may be different, so that the micro-processing unit 110 of the smart watch 100 may identify whether the air bag 180 or the dust cover 400 is mounted at this time based on the difference of different voltage values detected when the air bag 180 or the dust cover 400 is mounted.

Fig. 5 shows a schematic diagram of a principle of voltage variation based on hall effect phenomenon according to an embodiment of the present application.

It will be appreciated that the hall effect is one type of electromagnetic effect in that when a current is passed through a semiconductor perpendicular to an external magnetic field, carriers are deflected and an additional electric field is generated perpendicular to the direction of the current and magnetic field, thereby creating a potential difference across the semiconductor, a phenomenon known as the hall effect, which is also known as the hall potential difference. In the present embodiment, such a hall potential difference may cause the voltage value across the hall sensor 163 to increase beyond a preset voltage threshold.

As shown in the left side of FIG. 5, when the air bag 182 or the dust cover 400 is in the mounted state, the magnet 182 approaches the Hall sensor 163 to generate Hall effect, resulting in an increase of the voltage across the Hall sensor 163, so that the micro voltmeter on the circuit where the Hall sensor 163 is located can detect a larger voltage value, such as the detected voltage value V ₁ ＞V _k Wherein V is _k The preset voltage threshold may be, for example, a voltage level between the voltage values detected by the micro voltmeter before and after the hall effect, or may be another voltage level that is set reasonably, which is not limited herein.

As shown in the right side of FIG. 5, when the air bag 182 or the dust cover 400 is in a detached state, the magnet 182 is far away from the Hall sensor 163, the Hall effect disappears, and the voltage across the Hall sensor 163 is reduced, so that the micro voltmeter on the circuit where the Hall sensor 163 is located can detect a smaller voltage value, for example, the detected voltage value V at this time ₂ ＜V _k 。

Accordingly, the smart watch 100 can determine whether the airbag 180 or the dust cover 400 is detached from the body 101 of the smart watch 100 by detecting whether the voltage when the airbag 180 is attached or detached exceeds a preset voltage threshold.

In other embodiments, the smart watch 100 may also detect whether the airbag 180 or the dust cap 400 is detached in other ways, such as by switching on and off electrode contacts, or by a touch sensor or the like, and bluetooth or NFC connection or the like.

As an example, fig. 6a to 6c show schematic circuit diagrams of detecting whether the airbag 180 or the dust cap 400 is detached by the on-off of the electrode contacts.

Referring to fig. 6a, for example, an electrode contact 610 for connecting a resistor is provided on a body 101 of the smart watch 100, and a detection circuit shown in fig. 6a is provided in the body 101, and detects a voltage value at both ends of the electrode contact 610, for example, by a micro voltmeter. Correspondingly, a resistor 620 is disposed at a corresponding position of the airbag 180 or the dust cover 400. When the air bag 180 or the dust cover 400 is in the installation state, the two ends of the resistor 620 are connected with the electrode contacts 610, the circuit is conducted, the voltage value of the two ends of the electrode contacts 610 detected by the micro voltmeter is the voltage of the two ends of the resistor 620, and is recorded as V ₃ . When the airbag 180 or the dust cap 400 is in a disassembled state, two ends of the resistor 620 are separated from the electrode contact 610, the circuit is disconnected, and the voltage value of the two ends of the electrode contact 610 detected by the micro voltmeter is the power supply voltage and is recorded as V ₄ . It will be appreciated that V ₃ ＜V ₄ . That is, if the smart watch 100 is provided with a size of V ₃ And V is equal to ₄ Voltage threshold V between _k I.e. V ₃ ＜V _k1 ＜V ₄ ThenBased on the schematic circuit diagram shown in fig. 6a, the micro control unit 110 of the smart watch 100 may determine the voltage value across the detected electrode contact 610 by comparing the voltage value with V _k1 A comparison is made to determine whether the airbag 180 or the dust cap 400 has been detached.

Referring to fig. 6b, for example, an electrode contact 610 for connecting a resistor is provided on a watch body 101 of the smart watch 100, and a detection circuit shown in fig. 6b is provided in the watch body 101, the detection circuit is provided with a fixed resistor 630 and a ammeter, the circuit where the fixed resistor 630 is located is connected in parallel with the circuit where the electrode contact 610 is located, and the ammeter can be used for detecting a current value on a main circuit. When the airbag 180 or the dust cover 400 is in the mounted state, the two ends of the resistor 620 are connected with the electrode contacts 610, the circuit is conducted, the resistor 620 is connected with the resistor 630 in parallel, and the current value detected by the ammeter is I ₁ . When the airbag 180 or the dust cover 400 is in a detached state, two ends of the resistor 620 are separated from the electrode contacts 610, the circuit is disconnected, and the current value detected by the ammeter is I ₂ . It can be appreciated that since the resistance value of resistor 620 in parallel with resistor 630 is less than the resistance value of resistor 630, 1 ₁ ＞I ₂ . That is, if a size of 1 is set on the smart watch 100 ₁ And I ₂ Current threshold I in between _k I.e. 1 ₁ ＞I _k ＞I ₂ Based on the schematic circuit diagram shown in fig. 6b, the micro control unit 110 of the smart watch 100 may determine the detected current value and I _k A comparison is made to determine whether the airbag 180 or the dust cap 400 has been detached.

Referring to fig. 6c, for example, an electrode contact 610 for connecting a resistor is provided on a body 101 of the smart watch 100, and a detection circuit shown in fig. 6c is provided in the body 101, and detects a current value on a circuit where the electrode contact 610 is located, for example, by a ammeter. Correspondingly, a resistor 620 is disposed at a corresponding position of the airbag 180 or the dust cover 400. When the air bag 180 or the dust cover 400 is in the installation state, the two ends of the resistor 620 are connected with the electrode contacts 610, the circuit is conducted, and the ammeter detects the current value I ₁ . In the disassembled state of the airbag 180 or the dust cap 400, both ends of the resistor 620 are separated from the electrode contactsPoint 610, circuit open, amperometric detection of current value I ₂ . It will be appreciated that I ₃ ＞I ₄ Wherein I ₄ The value of (2) may be 0 or a small current value preset on the ammeter, without limitation. That is, if a size between I is set on the smart watch 100 ₃ And I ₄ Voltage threshold I between _k1 I.e. I ₃ ＞I _k1 ＞I ₄ If based on the circuit schematic diagram shown in fig. 6c, the micro control unit 110 of the smart watch 100 may calculate the detected current value by comparing the detected current value with I _k1 A comparison is made to determine whether the airbag 180 or the dust cap 400 has been detached.

In other embodiments, other types of detection circuits than those shown in fig. 6a to 6c may be provided in the body 101 of the smart watch 100, and the air bag 180 or the dust cap 400 may be determined by the change of the voltage or the current detected by the micro voltmeter or the ammeter, which is not limited herein.

It will be appreciated that in the implementation of the circuit principle of detecting whether the air bag 180 or the dust cover 400 is detached by the on-off of the electrode contacts shown in fig. 6a to 6c, the resistance value of the resistor 620 provided on the air bag 180 may be different from the resistance value of the resistor 620 provided on the dust cover 400, so that the micro-processing unit 110 of the smart watch 100 may recognize whether the air bag 180 or the dust cover 400 is mounted at this time based on the difference of different voltage values or current values or the like detected when the air bag 180 or the dust cover 400 is mounted.

Based on the structures of the smart watch 100, the air bag 180, the dust cover 400, and the like shown in fig. 1, 3, and 4a and the principle of detecting whether the air bag or the dust cover is detached or not shown in fig. 5, 6a to 6c, the following description will be given of the specific implementation procedure of the dust prevention method provided in the embodiment of the present application through different embodiments.

In the following, by way of example 1, the smart watch 100 is described to determine whether to enter an active dustproof state and prompt a user to install the dust cap or the air bag in time by identifying whether the air bag or the dust cap is detached from the air charging port.

Example 1

In this application embodiment, intelligent wrist-watch 100 through implementing the dustproof method that this application embodiment provided, can in time open dustproof function when gasbag or shield are dismantled to remind the user to install gasbag or shield as early as possible, thereby reduce the risk that the inflation inlet was polluted by the dust, avoid inflation inlet and gas circuit to switch on the jam such as subassembly, and then reduce the probability that the blood pressure measurement function of intelligent wrist-watch 100 breaks down.

Fig. 7 is a schematic flow chart of an implementation of a dust-proof method according to an embodiment of the application. It can be understood that, in the embodiment of the present application, the execution subject of each step in the flow shown in fig. 7 is the smart watch 100, and is specifically implemented by the micro control unit 110, the air pressure sensor 162, the air pump 170, and the like of the smart watch 100. In the following, when each step of the flow shown in fig. 7 is introduced, the description of the execution subject of each step is not repeated.

As shown in fig. 7, the flow includes the steps of:

701: the airbag or dust cap is detected to detach from the watch body.

Illustratively, referring to the structure shown in fig. 3, a hall sensor 163 is disposed in the watch body 101 of the smart watch 100, and a magnet 182 may be disposed in the air bag 180. The smart watch 100 can recognize whether the air bag 180 is detached from the watch body by detecting the voltage change at both ends of the hall sensor 163 through the hall effect generated by the magnet 182 and the circuit where the hall sensor 163 is located.

Specifically, the smart watch 100 may refer to the process of detecting whether the air bag or the dust cover is detached from the watch body based on the hall effect, etc., as shown in fig. 5 and fig. 6a to 6c and described in the related description, which will not be repeated here.

702: the air pump is started with a preset duty ratio, and the air inflation inlet is inflated to prevent dust.

For example, referring to the structure shown in fig. 1, when the smart watch 100 detects that the air bag 180 is detached from the watch body, the micro-processing unit 110 may control the air pump 170 to be started and start the air pump at a preset duty ratio, and the air pump may blow air at a certain blowing rate. At this time, the air bag 180 is detached from the watch body, the air charging port 171 is separated from the air bag air tap 181, and the air flow generated by the operation of the air pump 170 is blown out from the air charging port 171, so that dust does not fall to the air charging port 171, and the purpose of dust prevention of the air charging port can be achieved. It will be appreciated that during the process of measuring blood pressure by the smart watch 100, the duty cycle of the air pump is between 5% and 20%, and thus the preset duty cycle may be set to any value between 5% and 20%.

The Duty Ratio (DR) refers to the Ratio of the power-on time to the total time in one pulse cycle, and is also called Duty cycle or Duty cycle.

In the embodiment of the present application, the preset duty cycle may be a preferable value determined through experiments. It can be understood that at a certain operating frequency, the larger the duty cycle of the air pump operation, the larger the corresponding blowing rate, and the larger the air pump power consumption. Therefore, the air pump is started at a preset duty ratio, and the corresponding blowing rate can blow dust away from the air charging port 171 by a certain distance, thereby achieving the purpose of dust prevention. The preset duty cycle may be, for example, 5% or other reasonably preset value, without limitation.

703: the interface prompts that the active dust prevention is started and reminds a user to install the air bag or the dust prevention cover in time so as to prevent the air charging port from being polluted by dust.

Illustratively, when the smart watch 100 detects that the air bag 180 is detached from the watch body and performs the above step 702, a corresponding prompt message may also be displayed on the display screen 130 of the smart watch 100 to remind the user to install the air bag or the dust cap in time.

The interface for displaying the prompt information on the smart watch 100 may be shown in fig. 2, where the prompt information box 211 and the close button 212 are displayed on the prompt interface 210 displayed on the smart watch 100, and the prompt information displayed in the information prompt box 211 may be, for example, "the active dustproof function is opened, please install an air bag or a dust cover in time, and avoid dust pollution", and the user may click the close button 212 to close the information prompt box 211.

704: it is detected that the airbag or the dust cover is mounted.

Illustratively, the user may install the air bag or dust cover on the watch body after seeing the prompt message displayed by the smart watch 100, at which point the smart watch 100 may detect that the air bag or dust cover is installed via the hall effect or other principles. The process of detecting whether the air bag or the dust cover is mounted or not by the smart watch 100 according to the hall effect or other principles can be referred to the process of detecting whether the air bag or the dust cover is detached from the watch body according to the hall effect or other principles of the smart watch 100, that is, refer to fig. 5, fig. 6a to fig. 6c and the related description, and the detailed description is omitted herein.

The smart watch 100 can identify whether the air bag or the dust cover is installed through the mark information arranged on the air bag or the dust cover; the air bag and the dust cover may also be distinguished by distinguishing the magnetic magnitude or the resistance magnitude of the magnet 182 provided on the air bag or the dust cover, etc., so that the smart watch 100 may recognize whether the air bag or the dust cover is mounted based on the magnitude of the detected voltage value, without limitation.

705: the interface prompts that the air bag or dust cap is installed and exits the active dust prevention.

Illustratively, when the smart watch 100 detects that the air bag or the dust cover is mounted, a corresponding prompt message may be displayed through the display screen 130 of the smart watch 100 to feed back the mounted state of the air bag or the dust cover to the user. At this time, the smart watch 100 may control the air pump 170 to stop working and exit the active dustproof state.

It will be appreciated that if the user, after seeing the prompt message displayed by the smart watch 100, installs the air bag or the dust cover on the watch body, the smart watch 100 does not display the message that the corresponding prompt air bag or dust cover has been installed, indicating that the air bag or dust cover may not be installed.

By way of example, fig. 8 shows a schematic interface diagram of a smart watch 100 prompting a user that an air bag or dust cap is installed, in accordance with an embodiment of the present application. As described above in fig. 5 and fig. 6a to 6c, the micro processing unit 110 of the smart watch 100 may recognize whether the airbag 180 or the dust cover 400 is mounted at this time, based on differences in different voltage values or current values or the like detected in the mounted state of the airbag 180 or the dust cover 400.

As shown in fig. 8 (a), the reminder interface 810 displayed on the smart watch 100 includes a reminder information box 811 and a closing notification button 812, and the reminder information box 811 may be displayed with content such as "the airbag is installed" or the like, and the user may click the closing notification button 812 on the reminder interface 810 to close the reminder information box 811.

As shown in fig. 8 (b), the reminder interface 820 displayed on the smart watch 100 includes a reminder frame 821 and a closing notification button 822, and the reminder frame 821 may be displayed with contents such as "dust cap is mounted" and the user may click the closing notification button 822 to close the reminder frame 821 on the reminder interface 820.

As described above, the embodiment of the application specifically describes a process of when the smart watch 100 is detached from the identification air bag or the dust cover, enabling the active dust-proof function to enter the active dust-proof state, and opening the air pump to blow and dust the inflation inlet, so as to achieve the dust-proof purpose. In the following, a specific implementation process of determining whether active dust prevention is needed when the identification air bag or the dust cap of the smart watch 100 is detached and then performing dust prevention based on the determination result will be described in another embodiment.

Example 2

In the embodiment of the present application, by implementing the dustproof method provided in the embodiment of the present application, the smart watch 100 may determine whether to start the dustproof function based on a preset determination condition when the air bag or the dustproof cover is detached; and then, when the dustproof function is confirmed to be started according to the judging result, the air pump is started to blow air to the air charging port so as to realize the dustproof purpose. In this way, the smart watch 100 can be prevented from frequently entering the active dustproof state, that is, the air pump is frequently started, so that the energy consumption of the smart watch 100 is increased, and the loss of elements such as the air pump is possibly accelerated.

Fig. 9 shows a schematic flow chart of another dust prevention method according to an embodiment of the application. It can be understood that, in the embodiment of the present application, the execution subject of each step in the flow shown in fig. 9 is the smart watch 100, and is specifically implemented by the micro control unit 110, the air pressure sensor 162, the air pump 170, and the like of the smart watch 100. In the following, when each step of the flow shown in fig. 9 is introduced, the description of the execution subject of each step is not repeated.

As shown in fig. 9, the flow includes the steps of:

901: the airbag or dust cap is detected to detach from the watch body.

The execution of this step is the same as that of step 701 in embodiment 1, and the specific execution process may refer to the description related to step 701, which is not repeated here.

902: judging whether the condition of active dust prevention is satisfied. If yes, that is, the condition for performing active dust prevention is satisfied, the following step 903 is continuously executed to perform active dust prevention; if the determination result is no, that is, the condition for active dust prevention is not satisfied, the following step 907 is executed, and the current flow is ended.

Illustratively, in the above step 901, referring to the description related to step 701 in the above embodiment 1, when the air bag or the dust cover is detached from the watch body, the micro control unit 110 of the smart watch 100 may determine that the air bag or the dust cover is detached when the detected voltage value is reduced, for example, is reduced below a preset voltage threshold, based on the hall effect phenomenon. At this time, the micro control unit 110 of the smart watch 100 may determine whether to perform active dust prevention based on a preset condition for performing active dust prevention. The condition may be, for example, a time threshold judgment condition.

As an example, for example, a lower time threshold of the interval time between two active dustproof processes is preset on the smart watch 100, and when the micro control unit 110 of the smart watch 100 may calculate the time interval between the time when the airbag or the dustproof cover is detected to be detached this time and the time when the active dustproof function is turned on last time. If the micro control unit 110 determines that the time interval is greater than the preset lower time threshold, it may be determined that the condition for active dust prevention is satisfied at this time; if the micro control unit 110 determines that the time interval is less than or equal to the preset lower limit time interval, it may be determined that the active dust prevention condition is not satisfied at this time.

There is no limitation in this regard.

In other embodiments, the preset conditions for active dust prevention may be other conditions than the time threshold, which is not limited herein.

In the following, when the smart watch 100 is actively dustproof according to another embodiment, it may be determined that corresponding blockage clearing measures are adopted for clearing blockage according to the detected air pressure difference, for example, the user is prompted to go to after-sales service for clearing through an interface.

Example 3

In this embodiment of the present application, through implementing the dustproof method that this embodiment provided on the smart watch 100, realize carrying out initiative dustproof when gasbag or shield are dismantled, confirm whether the gas circuit passageway has the jam according to the atmospheric pressure difference that the smart watch 100 detected, and jam degree etc. the smart watch 100 is based on the atmospheric pressure difference that detects then can control to take the clear stifled measure that corresponds to different degree and block up and clear up the gas circuit passageway, for example in the serious jam of gas circuit passageway, detect under the great circumstances of atmospheric pressure difference angle and prompt the user to go to after-sales service and clear up. So, the problem that the gas circuit passageway was blocked can in time be in time found to the user of being convenient for when using intelligent wrist-watch 100 to can and carry out corresponding processing according to the suggestion, thereby avoid appearing because of the gas pump that the gas circuit passageway is blocked and the gas pump that leads to aerifys to the gasbag, and the blood pressure measurement function breaks down scheduling problem.

Fig. 10 is a schematic flow chart of another dust-proof method according to an embodiment of the present application. It can be understood that, in the embodiment of the present application, the execution subject of each step in the flow shown in fig. 10 is the smart watch 100, and specifically, the steps are implemented by the micro control unit 110, the air pressure sensor 162, the air pump 170, and the like of the smart watch 100. In the following, when each step of the flow shown in fig. 10 is introduced, the description of the execution subject of each step is not repeated.

As shown in fig. 10, the flow includes the steps of:

1001: the airbag or dust cap is detected to detach from the watch body.

1002: the air pump is started with a preset duty ratio, and the air inflation inlet is inflated to prevent dust.

1003: and detecting air pressure difference values at two ends of the air path from the air pump to the air charging port, and judging whether the air pressure difference values exceed a preset air pressure difference value threshold value or not. If yes, indicating that the air charging port or the air path conducting assembly is blocked, executing the following step 1005, determining the blocking degree and adopting corresponding blocking clearing measures; if the result of the determination is no, it indicates that the inflation port or the air path conducting assembly is unblocked, so that the air pump 170 will not be affected to inflate the air bag after the air bag 180 is installed, and step 1004 may be executed at this time, so that the air pump 170 keeps the current duty ratio to work, and dust removal is continued.

Illustratively, referring to the structure shown in fig. 1, the air pump 170 in the smart watch 100 is connected to the air charging port 171 through the air passage conducting assembly, and when the air charging port 171 is connected to the air bag nozzle 181, the air pump 170 is operated to charge the air bag 180. Referring to fig. 1, an air pressure sensor 162 may be disposed on and in communication with the air path conduction assembly. The air pressure sensor 162 is positioned, so that the air pressure can be measured by detecting the air pressure difference value at two sides of the air channel, or whether the air channel is blocked or not can be detected in the process of active dust prevention when the air bag 180 is taken off. It will be appreciated that the greater the difference in air pressure detected by the air pressure sensor 162, the more severe the blockage at the inflation port or within the air circuit conduction assembly.

It will be appreciated that the process of detecting the air pressure difference across the air path channel by the air pressure sensor 162 may last for 2s or 3s, or other reasonable time period, to ensure that the detection result is stable and accurate, which is not limited herein.

It will be appreciated that the predetermined differential air pressure threshold may be one threshold or a plurality of thresholds. If the preset air pressure difference threshold is a threshold, the blocking removal measure adopted by the smart watch 100 when executing the following step 1005 may be, for example, prompting the user to go to the after-sales service department for blocking removal and ending dust prevention; if the preset air pressure difference threshold is a plurality of thresholds, the smart watch 100 may compare the detected air pressure difference with the preset thresholds, and determine which threshold range the detected air pressure difference is in, so as to perform the blocking removal processing by adopting the blocking removal measure corresponding to the corresponding pressure difference threshold range when executing step 1005, for example, controlling the air pump to work to blow and remove the blocking, or prompting the user to go to the after-sale service place to perform blocking removal through the interface, etc. Reference may be made specifically to the following description in step 1005, which is not repeated here.

1004: and controlling the air pump to keep the current duty ratio to work, and continuing to prevent dust.

In the step 1003, the smart watch 100 determines that the air pressure difference value does not exceed the preset first preset value based on the air pressure difference value detected by the air pressure sensor 162, which indicates that the inflation port or the air passage conduction assembly is unblocked, and at this time, the smart watch 100 may control the air pump to keep the current duty ratio to continue to work for active dust prevention.

1005: and determining a blockage removing measure corresponding to the detected air pressure difference value, and performing blockage removing treatment. The blockage removing measures comprise blockage removing according to the blowing rates preset corresponding to the air pressure difference values in different ranges, or prompting the user to go to the after-sales service place for blockage removing through an interface, ending dust prevention and the like.

In some embodiments, the preset barometric pressure difference threshold may be a certain value. For example, when the preset air pressure difference threshold is 10mmHg, when the smart watch 100 determines that the detected air pressure difference exceeds 10mmHg when executing the above step 1003, it indicates that there is a blockage at the air charging port or in the air path conducting assembly, the step may be executed, and the user is prompted to go to the after-sale service place to clear the blockage and end to prevent dust through the interface.

In other embodiments, the preset barometric pressure difference threshold may be a plurality of barometric pressure difference thresholds (i.e., a plurality of thresholds). At this time, the micro control unit 110 of the smart watch 100 may compare the currently detected air pressure difference value with a preset plurality of threshold values, and determine a blockage removal measure corresponding to the detected air pressure difference value, for example, control to increase the duty ratio corresponding to the detected air pressure difference value to increase the blowing rate, so as to clear blockage to a corresponding extent, which is not limited herein. Therefore, the situation that the air pump works at a larger duty ratio when the air channel is slightly blocked can be avoided, and the energy consumption of the intelligent watch 100 is saved.

For example, if the preset 2 air pressure difference thresholds on the smart watch 100 are 5mmHg and 10mmHg respectively, when the smart watch 100 determines that the detected air pressure difference exceeds 5mmHg but does not exceed 10mmHg in executing the above step 1003, the smart watch 100 may control to increase the duty cycle of the air pump 170, so that the air pump 170 increases from the current air blowing rate to a larger air blowing rate, and the current air channel blockage is blown and cleared. When the detected air pressure difference exceeds 10mmHg, the smart watch 100 may control to display a prompt interface, for example, through the display screen 130, to display a prompt message, prompt the user to go to the after-sales service department for blocking, and control to close the air pump 170 to end dust prevention, so that the air pump power consumption may be reduced to a certain extent.

It is understood that the preset air pressure difference thresholds may also be 3 thresholds and more than 3 thresholds, which are not limited herein. The threshold range corresponding to the two adjacent thresholds can correspond to a force blocking removal measure. The greater the difference in air pressure detected by the smart watch 100, the more severe the occlusion may be.

It can be appreciated that when the smart watch 100 detects that the air charging port or the air passage conduction component is blocked to a slight degree, the air passage channel can be cleaned by controlling to improve the duty ratio of the air pump under the current working frequency of the air pump, so that the air blowing rate is improved. In other embodiments, the smart watch 100 may also increase the blowing rate and clear the air path channel by controlling the increase in the operating frequency and duty cycle of the air pump. There is no limitation in this regard.

FIG. 11 illustrates an interface diagram that indicates the presence of a severe blockage in a gas path channel, according to an embodiment of the present application.

As shown in fig. 11, a reminder interface 1110 is displayed on the screen of the smart watch 100, where the reminder interface 1110 includes a reminder information box 1111, and the reminder information displayed in the information reminder box 1111 may be, for example, "the air channel is blocked seriously, please go to after-sales service for cleaning as soon as possible", so as to prompt the user that the air channel of the smart watch 100 is blocked seriously at this time and needs to be cleaned.

As further shown in fig. 11, the alert interface 1110 displayed on the smart watch 100 further includes a close notification button 1112, and the user may click on the close notification button 1112 to close the information prompt box 1111 on the alert interface 1110 displayed on the smart watch 100. When the user goes to the after-sales service and cleans the air channel in the smart watch 100, the smart watch 100 can normally execute each step implemented by the dustproof method provided by the embodiment of the present application when working.

It can be appreciated that, according to the dustproof method provided by the embodiment of the application, when the air bag or the dustproof cover is detached, the corresponding blockage clearing measures are determined to clear the air path according to the detected air pressure difference, for example, under the conditions of serious blockage and large detected air pressure difference, the user can be prompted to go to after-sales service for clearing through an interface. So, the user of being convenient for can in time discover the jam problem of gas circuit passageway and in time handle when using wearing equipment such as intelligent wrist-watch 100 that has blood pressure measurement function to avoid because of the gas pump that the gas circuit passageway jam leads to the gasbag aerify the jam, even blood pressure measurement function breaks down scheduling problem.
