Abstract
Description
Technical Field
[0001] This application relates to the field of medical devices, and more particularly to a portable electronic product. Background Technology
[0002] Medical devices, including portable electronic products such as blood pressure monitors, blood glucose meters, and electrocardiogram (ECG) recorders, have played an increasingly important role in health management, disease prevention, and treatment in recent years. Compared to traditional medical devices, portable electronic products are characterized by their small size, ease of operation, and ability to monitor users' physiological indicators in real time, enabling timely detection of health problems.
[0003] Currently, portable electronic products primarily use batteries for power. However, even when the user is not operating the portable electronic product, its internal modules remain active, resulting in high standby power consumption and short battery life.
[0004] Therefore, in order to extend the usage time of portable electronic products, power management technology is usually used to reduce the standby power consumption of portable electronic products. For example, the entire circuit of the portable electronic product is put into a sleep standby state, and then the sleep current is used to wake it up when needed.
[0005] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this application and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this application. Utility Model Content
[0006] The inventors discovered that with the development of portable electronic products, these products are becoming increasingly miniaturized, leading to smaller built-in batteries and consequently smaller battery capacities. This necessitates increasingly stringent power consumption requirements, especially before products leave the warehouse and are sold, where lower power consumption is paramount. However, using a quiescent current to wake up circuits in a dormant standby state consumes a significant amount of power for low-capacity batteries, which is detrimental to long-term product storage. Furthermore, batteries operating under quiescent current for extended periods experience reduced charge recovery rates and shorter lifespans. Therefore, achieving low standby power consumption in portable electronic products while ensuring battery lifespan remains a crucial problem to solve.
[0007] To address at least one of the aforementioned technical problems or other similar issues, embodiments of this application provide a portable electronic product capable of achieving low power consumption in standby mode and extending battery life.
[0008] According to one aspect of the embodiments of this application, a portable electronic product is provided, the portable electronic product comprising:
[0009] An internal power supply that powers the portable electronic product;
[0010] A locking circuit, connected between the internal power supply and other circuits of the portable electronic product, is used to lock the power supply to the internal power supply in the default state.
[0011] A controller, which is connected to the locking circuit, controls the locking circuit to unlock upon detecting an external power source.
[0012] In some embodiments, when the locking circuit is in a "locked" state, the circuit between the locking circuit and the internal power supply is disconnected; when the locking circuit is in a "unlocked" state, the circuit between the locking circuit and the internal power supply is connected.
[0013] In some embodiments, when the controller receives an insertion signal from an external power source and confirms that the insertion signal is valid, the controller controls the locking circuit to unlock.
[0014] In some embodiments, the portable electronic product further includes: a detection circuit connected to the controller, which detects whether an external power source is inserted; when the detection circuit detects that an external power source is inserted, the detection circuit sends the insertion signal to the controller.
[0015] In some embodiments, the portable electronic product further includes a power switching circuit connected to the locking circuit and the external power source, for switching the power source supplying the portable electronic product; when both the external power source and the internal power source are in an on state, the power switching circuit switches the power source supplying the portable electronic product to the power source with the higher voltage between the external power source and the internal power source.
[0016] In some embodiments, the portable electronic product further includes a voltage conversion circuit connected to the power switching circuit and the other circuits for converting the output voltage to a value suitable for the other circuits, the other circuits including circuits connected to the controller.
[0017] In some embodiments, the external power supply or the internal power supply powers the controller through the voltage conversion circuit.
[0018] In some embodiments, the internal power source is a lithium battery.
[0019] In some embodiments, the portable electronic product described in any of the above embodiments is an electrocardiogram (ECG) recorder.
[0020] One of the beneficial effects of this application embodiment is that: when the portable electronic product is in the default state, the locking circuit is in the locked state to ensure the low standby power consumption of the internal power supply, reduce the power consumption of the internal power supply, and extend the usage time of the internal power supply; after the external power supply is plugged in, the portable electronic product is woken up by the external power supply, avoiding the internal power supply from using the hibernation current to wake up the portable electronic product, thus extending the usage time and service life of the internal power supply.

[0034] The embodiments of this application will now be described in conjunction with the accompanying drawings.
[0035] Figure 1 This is a circuit diagram of a portable electronic product according to an embodiment of this application, showing the overall circuit structure of the portable electronic product, such as... Figure 1 As shown, the portable electronic product 100 includes: an internal power supply 101, a locking circuit 102 connected between the internal power supply 101 and other circuits of the portable electronic product, and a controller 103 connected to the locking circuit 102. The internal power supply is used to power the portable electronic product, the locking circuit 102 is used to lock the power supply to the internal power supply 101 in the default state, and the controller 103 is used to lock the power supply to the internal power supply 101 when an external power supply 104 is detected. Figure 1 (Not shown) After the control lock circuit 102 is unlocked.
[0036] In this application embodiment, the default state refers to the state of the portable electronic product before it is officially put into use, or a state that has not been used for a long time, or a predefined state, such as the state at the time of manufacture, before sale, after a long period of inactivity, or a user-defined state. This application is not limited to these. In the default state, the power consumption requirement for the portable electronic product should be as low as possible, so as to ensure its working time and extend its service life.
[0037] In this application embodiment, the portable electronic product can be a product with low power consumption requirements during storage, such as a portable electrocardiogram recorder, etc., and this application is not limited to this. Furthermore, in this application embodiment, the internal power source is, for example, a lithium battery, whose small size makes it suitable for miniaturized portable electronic products; however, its low battery capacity leads to relatively high power consumption requirements. In this application implementation, a lithium battery is used as an example for illustration, but this application is not limited to this; the internal power source can also be a lithium polymer battery, nickel-metal hydride battery, etc.
[0038] According to the embodiments of this application, when the portable electronic product is in the default state, the locking circuit is in the locked state, the internal power supply is disconnected from the entire circuit of the portable electronic product, and no power is supplied to the entire circuit of the portable electronic product. Only the internal power supply itself consumes power. Therefore, the low standby power consumption of the internal power supply can be guaranteed, the power consumption of the internal power supply can be reduced, and the usage time of the internal power supply can be extended. After the external power supply is plugged in, the portable electronic product is woken up by the external power supply, avoiding the internal power supply using the dormant current to wake up the portable electronic product, thus extending the usage time and service life of the internal power supply.
[0039] In some embodiments, when the locking circuit is in the "locked" state, the circuit between the locking circuit and the internal power supply is disconnected. At this time, the internal power supply is disconnected from the entire circuit of the portable electronic product. Thus, the internal power supply does not supply power to the entire circuit of the portable electronic product, but only consumes its own power, ensuring the low power consumption requirement of the portable electronic product in the default state. When the locking circuit is in the "unlocked" state, the circuit between the locking circuit and the internal power supply is connected. At this time, the internal power supply is connected to the entire circuit of the portable electronic product. Thus, the internal power supply can supply power to the entire circuit of the portable electronic product.
[0040] In this embodiment, the controller 103 controls the locking circuit to unlock after detecting an external power source. This application does not limit the specific detection method.
[0041] Figure 2 This is another circuit configuration diagram of the portable electronic product according to an embodiment of this application, such as... Figure 2As shown, in the default state, the external power supply 104 is not connected to the portable electronic product. When the external power supply 104 is plugged in, it can supply power to the entire circuit of the portable electronic product. At this time, after the controller 103 obtains power, it can detect the insertion of the external power supply 104. When the insertion of the external power supply 104 is detected, the controller controls the locking circuit 102 to unlock. The circuit between the locking circuit 102 and the internal power supply 101 is connected, so that the internal power supply 101 can supply power to the portable electronic product 100.
[0042] In some embodiments, when a portable electronic product enters a default state and the controller 103 detects that the portable electronic product is in a default state, the controller 103 controls the locking circuit 102 to lock. For example, when the user sets the portable electronic product 100 to a standby state, the controller 103 receives a signal that the portable electronic product 100 is in a standby state, or the controller 103 detects that the portable electronic product 100 is in a standby state. At this time, the controller 103 controls the locking circuit 102 to lock, that is, the locking circuit 102 disconnects the power supply of the internal power supply 101, and the internal power supply 101 does not supply power to the portable electronic product 100.
[0043] Therefore, when the portable electronic product is in the default state or is set to the default state, the controller 103 automatically controls the locking circuit 102 to lock, which simplifies the operation process, reduces the power consumption of the internal power supply, and extends the usage time of the internal power supply.
[0044] Figure 3 This is a schematic diagram illustrating the power supply of a portable electronic product via an external power source in a locked state, showing the default configuration with an external power source 104 plugged in. For example... Figure 3 As shown, in the default state, when an external power source 104 is plugged in, the external power source 104 can supply power to the controller 103 through the connection of the internal circuits of the portable electronic product (such as the power switching circuit 106, voltage conversion circuit 107, etc.). The controller 103 can start working after receiving current, for example, it can detect the insertion of the external power source, or, for example, it can control the unlocking of the locking circuit 102 after detecting the insertion of the external power source, etc.
[0045] Therefore, when the portable electronic product is in the default state, the controller is powered by an external power source to wake up the portable electronic product. As a result, the internal power source does not need to provide a sleep current to wake up the portable electronic product, which reduces the power consumption of the internal power source and extends the usage time and service life of the internal power source.
[0046] In some embodiments, the controller 103 detects the insertion of an external power source by, when the controller 103 receives an insertion signal from the external power source and confirms that the insertion signal is valid, considering that the external power source has been inserted. At this time, the controller 103 can control the locking circuit 102 to unlock.
[0047] For example, such as Figure 3 As shown, when the external power supply 104 is plugged in, it supplies power to the controller 103. After the controller 103 receives the insertion signal from the external power supply 104 and confirms that the insertion signal is valid, the controller 103 controls the locking circuit 102 to unlock. If the external power supply 104 fails to supply power to the controller 103 due to circuit failure or other problems after it is plugged in, the controller 103 will be in a power-off state and will not be able to receive and process the insertion signal from the external power supply 104, and thus will also be unable to control the locking circuit 102 to unlock.
[0048] Therefore, when the portable electronic product is in its default state, the controller can automatically unlock the locking circuit based on the insertion signal after an external power source is plugged in, simplifying the operation process.
[0049] In some embodiments, such as Figure 1 and Figure 2 As shown, the portable electronic product 100 also includes a detection circuit 105 connected to the controller 103, wherein the detection circuit 105 is used to detect whether an external power supply 104 is plugged in.
[0050] In some embodiments, the detection circuit 105 is a USB insertion detection circuit, but this application is not limited to this. The detection circuit 105 can also be a current detection circuit, a voltage detection circuit, etc. In addition, the detection circuit 105 can be set independently of the controller 103, or it can be part of the controller 103. It can also be implemented by circuitry, or by software or firmware.
[0051] In some embodiments, when the detection circuit 105 detects the insertion of an external power source, the detection circuit 105 can generate an insertion signal and provide it to the controller 103 for transmission. For example, as Figure 3 As shown, when the detection circuit 105 detects the insertion of the external power supply 104, the detection circuit 105 sends an insertion signal to the controller 103. The controller 103 receives the insertion signal and determines whether the insertion signal is a valid signal. If it is a valid signal, the controller 103 controls the locking circuit 102 to unlock.
[0052] In some embodiments, such as Figure 2 and Figure 3 As shown, the portable electronic product also includes a power switching circuit 106 connected to the locking circuit 102 and the external power supply 104, wherein the power switching circuit 106 is used to switch the power supply for the portable electronic product.
[0053] In some embodiments, when both the external power supply and the internal power supply are in the on state, the power switching circuit 106 switches the power supply for the portable electronic product to the power supply with the higher voltage between the external power supply and the internal power supply.
[0054] For example, such as Figure 3 As shown, when the voltage of the external power supply 104 is greater than the voltage of the internal power supply 101, the power switching circuit 106 selects the external power supply 104 to power the portable electronic product 100. Figure 4 This is a diagram illustrating how a portable electronic device is powered by an internal power source when the device is unlocked. Figure 4 As shown, when the voltage of the external power supply 104 is less than the voltage of the internal power supply 101, or when the external power supply 104 is not plugged into the portable electronic product 100, the power switching circuit 106 selects the internal power supply 104 to power the portable electronic product 100.
[0055] In some embodiments, such as Figures 1 to 4 As shown, the portable electronic product also includes a voltage conversion circuit 107 connected to a power switching circuit and other circuits, wherein the voltage conversion circuit 107 is used to convert the output voltage to a value suitable for other circuits 108, which include circuits connected to a controller 103.
[0056] In some embodiments, other circuits 108 include data acquisition circuits, memory card control circuits, etc., depending on the circuit configuration of the portable electronic product, and this application is not limited thereto.
[0057] Therefore, the voltage conversion circuit 107 ensures that the voltage input to the data acquisition circuit, memory card control circuit and other circuits is appropriate, protecting the data acquisition circuit, memory card control circuit and other circuits, and improving the performance of the data acquisition circuit, memory card control circuit and other circuits.
[0058] In some embodiments, an external or internal power source supplies power to the controller via a voltage conversion circuit 107. For example... Figure 2 As shown, when the locking circuit 102 is in the unlocked state, the external power supply 104 and the internal power supply 101 are in the conducting state with the power switching circuit 106. The power switching circuit 106 is connected to the voltage conversion circuit 107, and the voltage conversion circuit 107 is connected to the controller 103. Thus, the internal power supply 101 and the external power supply 104 can supply power to the controller 103 through the power switching circuit 106 and the voltage conversion circuit 107.
[0059] Therefore, the voltage conversion circuit ensures that the voltage input to the controller is appropriate, protecting the controller and improving its performance.
[0060] In some embodiments, the portable electronic product is an electrocardiogram recorder, but this application is not limited thereto. The portable electronic product may also be a blood pressure monitor, a blood glucose meter, etc.
[0061] Figure 5 This is another circuit diagram of a portable electronic product according to an embodiment of this application. Figure 5 In the example, taking the portable electronic product as an electrocardiogram recorder, the internal power supply 101 is a lithium battery, the detection circuit 105 is a USB insertion detection circuit, the external power supply 104 is a USB power supply, and the other circuits 108 include a data acquisition circuit 1081 and a memory card control circuit 1082.
[0062] like Figure 5 As shown, when the USB power supply 104 is plugged into the ECG recorder, the USB power supply 104 supplies power to the control manager 103, data acquisition circuit 1081, and memory card control circuit 1082 sequentially through the power switching circuit 106 and voltage conversion circuit 107. After the USB insertion detection circuit 105 detects the insertion of the USB power supply 104, it sends an insertion signal to the control manager 103. After the control manager 103 is connected to the USB power supply 104 and receives the insertion signal, the control manager 103 controls the locking circuit 102 to unlock, and the lithium battery 101 and... The circuits between the locking circuits 102 are connected; when the USB power supply 104 is not unplugged, the power switching circuit 106 selects the power supply with the larger voltage between the USB power supply 104 and the lithium battery 101 to supply power to the control manager 103, the data acquisition circuit 1081 and the memory card control circuit 1082. If the USB power supply 104 has been unplugged, the lithium battery 101 supplies power to the control manager 103, the data acquisition circuit 1081 and the memory card control circuit 1082 through the locking circuit 102 (conducting state), the power switching circuit 106 and the voltage conversion circuit 107.
[0063] Therefore, by designing the power supply circuit of the ECG recorder to be locked at the factory, the lithium battery does not supply power to the entire circuit of the ECG recorder. When there is a power demand, the lithium battery supplies power to the entire circuit of the ECG recorder, thereby reducing the power consumption of the ECG recorder before it is put into use and extending the life of the lithium battery.
[0064] Figure 6 This is a schematic diagram of the workflow of a portable electronic product according to an embodiment of this application, such as... Figure 6 As shown, the workflow includes:
[0065] 601: The locking circuit locks when the portable electronic product is set to the default state;
[0066] 602: Plug in an external power source to power portable electronic devices;
[0067] 603: After the detection circuit detects the insertion of an external power source, it sends an insertion signal to the controller;
[0068] 604: After receiving the insertion signal, the controller controls the locking circuit to unlock;
[0069] 605: Internal power supply for portable electronic products;
[0070] 606: Determine if the external power supply is unplugged. If yes, proceed to 607; otherwise, proceed to 609.
[0071] 607: Determine if the voltage of the external power supply is greater than the voltage of the internal power supply. If yes, proceed to 608; otherwise, proceed to 609.
[0072] 608: The power switching circuit selects an external power source to power the portable electronic product, returning to 606;
[0073] 609: The power switching circuit selects the internal power supply to power portable electronic products.
[0074] For example, such as Figure 1 As shown, when the portable electronic product 100 is in its default state, such as at the factory, the locking circuit 102 is in a locked state, and the internal power supply 101 does not supply power to the portable electronic product 100; that is, the internal power supply 101 only consumes power naturally and does not supply power to any circuit structure. Figure 2As shown, when the external power supply 104 is plugged into the portable electronic product 100, the external power supply 104 supplies power to the controller 103 through the power switching circuit 106 and the voltage conversion circuit 107. After the detection circuit 105 detects the insertion of the external power supply, it sends an external power supply insertion signal to the controller 103. After the controller 103 is powered by the external power supply 104, it can receive the external power supply insertion signal sent by the detection circuit 105 and determine that the portable electronic product 100 is currently powered by the external power supply 104. At this time, the controller 103 sends an unlocking control signal to the locking circuit 102. After receiving the unlocking control signal, the locking circuit 102 unlocks. At this time, the internal power supply 101 and the locking circuit 102 are in a conducting state, that is, the internal power supply 101 can supply power to other circuit structures inside the portable electronic product 100. Since the external power supply 104 is not unplugged at this time, External power supply 104 can also power portable electronic product 100. In this case, power switching circuit 106 can choose whether external power supply 104 or internal power supply 101 powers portable electronic product 100. That is, power switching circuit 106 determines whether the voltage of external power supply 104 is greater than the voltage of internal power supply 101 in the current state. If the voltage of external power supply 104 is greater than the voltage of internal power supply 101 in the current state, then power switching circuit 106 selects external power supply 104 to power portable electronic product 100. If external power supply 104 is subsequently unplugged, power switching circuit 106 selects internal power supply 101 to power portable electronic product 100. If the voltage of external power supply 104 is less than the voltage of internal power supply 101 in the current state, then power switching circuit 106 selects internal power supply 101 to power portable electronic product 100.
[0075] It is worth noting that the above appendix Figure 6 The embodiments of this application have only been illustrated schematically, and the application is not limited thereto. For example, some of the above steps can be performed simultaneously or in a specific order, and the execution order between the various operations can be appropriately adjusted. Furthermore, other operations can be added or some operations can be removed. Those skilled in the art can make appropriate modifications based on the above description, and are not limited to the above-described embodiments. Figure 6 The records.
[0076] Figure 7 This is a schematic diagram of the working process of the controller of a portable electronic product according to an embodiment of this application, as shown below. Figure 7 As shown, the workflow includes:
[0077] 701: The controller is powered by an external power source;
[0078] 702: The controller receives the external power supply insertion signal sent by the detection circuit;
[0079] 703: The controller determines whether the external power supply signal is valid. If it is, it executes 704; otherwise, it returns to 702.
[0080] 704: The controller unlocks the locking circuit in its default state.
[0081] It is worth noting that the above appendix Figure 7 The embodiments of this application have only been illustrated schematically, and the application is not limited thereto. For example, some of the above steps can be performed simultaneously or in a specific order, and the execution order between the various operations can be appropriately adjusted. Furthermore, other operations can be added or some operations can be removed. Those skilled in the art can make appropriate modifications based on the above description, and are not limited to the above-described embodiments. Figure 7 The records.
[0082] In this embodiment, the controller is powered by an external power source to unlock the locking circuit, thus avoiding the consumption of internal power and extending the usage time and service life of the internal power source.
[0083] In this application embodiment, the default state refers to the state of the portable electronic product before it is officially put into use, or the state of not working for a long time, or a predefined state, such as the state at the time of manufacture, before sale, after a long period of non-working, or a user-defined state. This application is not limited to these states.
[0084] In some embodiments, when the locking circuit is in a "locked" state, the circuit between the locking circuit and the internal power supply is disconnected, and the internal power supply does not supply power to the controller; when the locking circuit is in a "unlocked" state, the circuit between the locking circuit and the internal power supply is connected, and the internal power supply supplies power to the controller through the locking circuit.
[0085] For example, such as Figure 1 As shown, when the controller 103 receives a signal that the portable electronic product 100 is in standby mode, or when the controller 103 detects that the portable electronic product 100 is in standby mode, the controller 103 controls the locking circuit 102 to lock, the circuit between the locking circuit 102 and the internal power supply 101 is disconnected, and the internal power supply 101 does not supply power to the controller 103; Figure 2 As shown, when the external power supply 104 is plugged in to power the controller 103, after the controller 103 receives a valid external power supply insertion signal, the controller 103 controls the locking circuit 102 to unlock, and the circuit between the locking circuit 102 and the internal power supply 101 is connected, and the internal power supply 101 powers the portable electronic product 100.
[0086] Therefore, based on the detected or received signal that the portable electronic product is in the default state, the controller automatically controls the locking circuit to lock. When an external power source is plugged in to power the controller, the controller automatically controls the locking circuit to unlock, which simplifies the operation process, reduces the power consumption of the internal power source, and extends the usage time of the internal power source.
[0087] In some embodiments, when the controller receives a valid external power supply insertion signal, the controller controls the locking circuit, which is in the default state, to unlock.
[0088] In some embodiments, when the detection circuit detects the insertion of an external power source, the controller receives an insertion signal sent by the detection circuit.
[0089] In some embodiments, when both the external power supply and the internal power supply are in the on state, the controller ensures, through a power switching circuit, that the power supply that powers itself is the power supply with the higher voltage between the external power supply and the internal power supply.
[0090] For example, such as Figure 3 As shown, when the voltage of the external power supply 104 is greater than the voltage of the internal power supply 101, the power switching circuit 106 determines that the voltage of the external power supply 104 is greater, and the controller is powered by the external power supply 104; as Figure 4 As shown, when the voltage of the external power supply 104 is less than the voltage of the internal power supply 101, or when the external power supply 104 is not plugged in, the power switching circuit 106 switches the internal power supply 104 as the power supply, and the controller is powered by the internal power supply 104.
[0091] In some embodiments, the controller is provided with an adapted input voltage by a voltage conversion circuit.
[0092] Therefore, the voltage conversion circuit ensures that the voltage input to other circuits and controllers is appropriate, protecting them and improving their performance.
