Description

Technical Field

[0001] The present invention relates to the technical field of oxygen concentrators, and in particular to a portable oxygen concentrator and a key control method, system and storage medium thereof. Background Art

[0002] Compared with large oxygen concentrators, portable oxygen concentrators are more suitable for home use, outdoor carrying or vehicle use. In order to meet the needs of parameter setting, current portable oxygen concentrators often adopt the following two solutions:

[0003] 1. A large number of buttons are set on the oxygen concentrator. These buttons include not only buttons for quick settings, but also buttons with low frequency of use. Since the actual operation of the user's fingers is large and the operation area is large, if the area of ​​each button is too small, it will cause misoperation; if the button area is too large, it will increase the product control area; if it is a touch screen, the area of ​​the touch screen must be large, which is contrary to the concept of the portable oxygen concentrator; and some parameters (such as high temperature alarm temperature threshold, low concentration alarm specific concentration, etc.) are not suitable for opening to users. The settings are too complicated and difficult for users to operate, which increases the difficulty of operation and poor experience.

[0004] Second, set a small number of buttons on the oxygen concentrator, and operate the buttons to control one or two quick parameters (such as sensitivity and sound volume). For the setting of other conventional parameters (such as brightness, whether the alarm can be released with one button, etc.), users are often required to adjust them on other smart devices (such as mobile phones, computers, etc.), and then control the oxygen concentrator, or use a wireless remote control (such as an infrared remote control) that is compatible with the oxygen concentrator to control the oxygen concentrator. On the one hand, users need to operate multiple devices at the same time, which gives a poor experience; on the other hand, for users or special groups in harsh environments (such as extreme weather on the plateau or extreme geographical locations), it is difficult to use other smart devices to control the oxygen concentrator. Summary of the invention

[0026] Figure 3 The present invention is a block diagram of a key control system of a portable oxygen concentrator according to an embodiment of the present invention. DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] The portable oxygen concentrator of the embodiment of the present invention includes a display screen and operation buttons. The display screen is used to display the operation page of the portable oxygen concentrator. The operation buttons include a first button, a second button and a third button. The first button is used to: turn on, turn off, switch normal parameters, switch authorized parameters, save current settings and exit the current operation page; the second button and / or the third button are used to: enter the quick parameter setting, enter the normal parameter setting, enter the authorized setting, and control the value. Among them, the operation button can be a press button or a touch button, which is not limited in this embodiment.

[0029] like Figure 1 As shown, the key control method of the portable oxygen concentrator according to the embodiment of the present invention includes:

[0030] S1, obtaining a state switching key operation instruction, and obtaining a pressing operation level corresponding to the state switching key operation instruction. The state switching key operation instruction includes a triggering duration and a triggering number of the triggered operation key.

[0031] In one embodiment of the present invention, the pressing operation levels may include: long pressing a single key once, long pressing two keys once, and long pressing two keys multiple times. Among them, long pressing and short pressing can be distinguished according to the duration of the key being pressed. A pressing operation with a pressing duration less than a preset pressing duration is a short press, and a pressing operation with a pressing duration greater than a preset pressing duration is a long press. The preset pressing duration can be set based on experience, such as 5 seconds, to facilitate operation by elderly people with slow movements, and can also be adjusted after entering the authorization setting.

[0032] It can be understood that long pressing a single button once is the simplest operation among the three levels, so its corresponding first preset control command is the most commonly used power on, power off, and entering the quick parameter setting, which is suitable for the elderly and most users. Among them, entering the quick parameter setting may include entering the sensitivity setting and the sound volume setting; long pressing two buttons once is more complicated, so its corresponding first preset control command is the less commonly used entry into the conventional parameter setting, and after executing the first preset control command, further operation is required, such as short pressing the first button to switch the conventional parameters, in order to set specific conventional parameters, which is suitable for some users who need to adjust the conventional parameters; long pressing two buttons multiple times is the most complicated operation. Under normal circumstances, users will not make mistakes and enter the corresponding first preset control command (enter the authorization setting). Therefore, the authorized parameters (such as the minimum or maximum value of the temperature alarm, the minimum value of the concentration alarm, the maximum value of the gas tank high pressure alarm, the low battery alarm value of the battery, etc.) will not be changed by ordinary users under normal circumstances, ensuring the stable operation of the oxygen concentrator.

[0033] S2, executing a corresponding first preset control command according to the triggered operation button and the corresponding pressing operation level in the state switching button operation instruction.

[0034] Specifically, the shortcut parameters may include sensitivity and sound volume. When the state switching button operation instruction is a long press of the first button, the first preset control command is to turn on or off the power. When the portable oxygen concentrator is in the on state, the first preset control command corresponding to a long press of the first button is to turn off the power; when the portable oxygen concentrator is in the off state, the first preset control command corresponding to a long press of the first button is to turn on the power; when the state switching button operation is a long press of the second button, the first preset control command is to enter the sensitivity setting; when the state switching button operation is a long press of the third button, the first preset control command is to enter the sound volume setting. When the state switching button operation is a long press of the second button and the third button, the first preset control command is to enter the general parameter setting. When the state switching button operation is a long press of the second button and the third button multiple times, the first preset control command is to enter the authorization setting.

[0035] S3, when the first preset control command executed is to enter the quick parameter setting, enter the regular parameter setting or enter the authorization setting, obtain an extended key operation instruction, the extended key operation instruction includes the triggering duration of the triggered operation key.

[0036] Specifically, when the first preset control command executed is to enter the sensitivity setting, the extended key operation instructions obtained can be short pressing the first button, short pressing the second button, and short pressing the third button. The corresponding second preset control commands are saving the current settings and exiting the current operation page, increasing the control sensitivity value, and decreasing the control sensitivity value. If after entering the sensitivity setting, no extended key operation instructions are obtained within the preset time, the current settings can be automatically saved and the current operation page can be exited.

[0037] When the first preset control command executed is to enter the volume setting, the extended key operation instructions obtained may be short pressing the first key, short pressing the second key, and short pressing the third key, and the corresponding second preset control commands are respectively saving the current settings and exiting the current operation page, increasing the volume value, and decreasing the volume value; if no extended key operation instructions are obtained within the preset time after entering the volume setting, the current settings can be automatically saved and the current operation page can be exited. The preset time can be a duration set according to experience or actual needs, such as 60 seconds, which is not limited in this embodiment.

[0038] When the first preset control command executed is to enter the general parameter setting, the extended key operation instructions obtained can be short press the first button, short press the second button, short press the third button, and long press the first button. The corresponding second preset control commands are switching general parameters, controlling the increase of general parameter values, controlling the decrease of general parameter values, saving current settings and exiting the current operation page.

[0039] When the first preset control command executed is to enter the authorization setting, the extended key operation instructions obtained can be short press the first button, short press the second button, short press the third button, and long press the first button. The corresponding second preset control commands are to switch authorization parameters, control the increase of authorization parameter values, control the decrease of authorization parameter values, save the current settings and exit the current operation page.

[0040] It can be understood that when the first preset control command executed is to enter the quick parameter setting, after adjusting the numerical value of the quick parameter, the user can choose to short press the first button to realize active saving, or can choose not to operate and automatically save the current setting after waiting for the preset time, which is a more convenient setting method; when the first preset control command executed is to enter the general parameter setting or enter the authorization setting, if the extended button operation instruction of long pressing the first button is not obtained, the current setting will not be saved, thereby avoiding erroneous operation and ensuring the safe and stable operation of the oxygen concentrator. In some other embodiments of the present invention, the extended button operation instruction may include the triggering duration and triggering number of the triggered operation button, and the extended button operation instruction corresponding to saving the current setting and exiting the current operation page may be set to long pressing the first button multiple times, long pressing multiple buttons at a time, etc., which is not limited in this embodiment.

[0041] In one embodiment of the present invention, when the first preset control command executed is power on, step S1 may be executed.

[0042] S4, executing a corresponding second preset control command according to the executed first preset control command and the triggered operation key and its triggering duration in the extended key operation instruction.

[0043] In one embodiment of the present invention, if the current operation page is not exited after the second preset control command is executed, step S3 may be continued to be executed to achieve flexible settings.

[0044] In one embodiment of the present invention, when the first preset control command executed by S2 is to enter the authorization setting, before step S3 it also includes: obtaining the authorization key operation, and identifying whether the authorization key operation complies with the preset authorization key operation; if it complies, executing step S3.

[0045] In one embodiment of the present invention, the preset authorization key operation can be a key operation set when the oxygen concentrator leaves the factory, or a key operation set when the oxygen concentrator is in use; the specific preset authorization key operation can be a short press of the second key and / or the third key several times. By setting complex preset authorization key operations, operators at different levels, such as R&D, after-sales, agents, outdoor product testing, special users, etc., can adjust the authorization parameters they need to adjust, which is convenient for operators at different levels to adjust the authorization parameters in real time.

[0046] In one embodiment of the present invention, when the first preset control command executed is to enter the sensitivity setting, the user can continue to press the second button or the third button again for multiple preset time gradients to increase or decrease the sensitivity value until it reaches the user's target value and then rises again, wherein the preset time gradient can be set according to experience or actual needs, and this embodiment does not limit it. Similarly, when entering other parameter settings, operations similar to this embodiment can be taken to adjust the parameter values, which will not be repeated here.

[0047] In one embodiment of the present invention, when the portable oxygen concentrator is in the default state, a flow adjustment operation instruction can also be obtained, and the flow rate gear of the portable oxygen concentrator per minute of oxygen output can be controlled according to the flow adjustment operation instruction, so that when the user is in urgent need of oxygen, the portable oxygen concentrator can be controlled to output oxygen at a large flow rate by controlling the flow rate gear, otherwise it will output oxygen at a small flow rate, so as to achieve flexible control of the flow rate gear. Among them, the flow adjustment operation instruction can be a short press of the second button or a short press of the third button. After the portable oxygen concentrator is turned on, it is generally in the default state; after performing quick parameter setting, regular parameter setting or authorized parameter setting and exiting the current operation page, it can also return to the default state; the flow rate gear can be set to 1 to 6 gears or 1 to 7 gears according to the size of the oxygen flow rate per minute, and can also be set according to the performance of the portable oxygen concentrator or actual needs, and this embodiment does not limit it.

[0048] Specifically, after the portable oxygen concentrator is turned on, the display screen can display the current flow level, which is generally the flow level recorded after the last use; when the flow adjustment operation instruction is a short press of the second button, the control flow level is increased; when the flow adjustment operation instruction is a short press of the third button, the control flow level is reduced.

[0049] In a specific embodiment of the present invention, the first button is an on / off button, the second button is an increase button, and the third button is a decrease button. The content on the display screen can prompt the current operation. The button control method of this embodiment can be set as follows:

[0050] 1. Basic function settings: Short press the increase key and decrease key to increase or decrease the control parameters. When the portable oxygen concentrator is in the off state, long press the power key to turn it on; when the portable oxygen concentrator is in the on state, long press the power key to turn it off; when the portable oxygen concentrator is in the default state, short press the increase key to increase the flow rate, and short press the decrease key to decrease the flow rate.

[0051] 2. Quick parameter setting: long press the increase key and then lift it to enter the sensitivity setting. Short press the increase key or decrease key to set flexibly. After exceeding the preset time (for example, 60 seconds), the current settings will be automatically saved and the current operation page will be exited. If you want to exit manually, you can directly short press the power key to immediately save the current settings and exit the current operation page.

[0052] Long press the decrease key and then lift it to enter the volume setting. Short press the increase key or decrease key to set it flexibly. After exceeding the preset time (for example, 60 seconds), the current settings will be automatically saved and the current operation page will be exited. If you want to exit manually, you can directly short press the power key to immediately save the current settings and exit the current operation page.

[0053] 3. General parameter settings: long press the increase key and the decrease key and then release them to enter the general parameter settings. Short press the power key N times to enter the Nth general parameter setting interface, then short press the increase key or decrease key to adjust the parameter value. Long press the power key and then release it to save the current settings and exit the current operation page.

[0054] 4. Authorization parameter setting: long press the increase key and the decrease key and lift them 2 or more times to enter the authorization identification state, then short press the increase key and / or the decrease key several times, and if it meets the preset authorization key operation, continue to obtain the extended key operation instruction, then short press the power key N times to enter the Nth authorization parameter setting interface, and then use the increase key or the decrease key to set. After the authorization setting is completed, long press the power key once or more to save the current settings and exit the current operation page.

[0055] According to the button control method of the portable oxygen concentrator of the embodiment of the present invention, it is only necessary to obtain the operations of the first button, the second button and the third button to realize the setting of the quick parameters, the normal parameters and the authorized parameters. The user does not need to use other smart devices to adjust the parameters. The method is not only applicable to plain areas, but also to plateau areas with harsh environments, and has good applicability. The pressing operations are divided into different levels of pressing operations, and the levels of different difficulties are suitable for different types of user operations, which can avoid the user from mistakenly entering the normal parameter settings or the authorized settings and effectively improve the user experience.

[0056] In addition, to achieve the above-mentioned purpose, the present invention also provides a key control system for a portable oxygen concentrator.

[0057] like Figure 2As shown, the key control system of the portable oxygen concentrator according to the embodiment of the present invention includes a first acquisition unit 10, a first execution unit 20, a second acquisition unit 30 and a second execution unit 40. Among them, the first acquisition unit 10 is used to acquire the state switching key operation instruction and obtain the pressing operation level corresponding to the state switching key operation instruction. The state switching key operation instruction includes the triggering duration and the number of triggering times of the triggered operation key; the first execution unit 20 is used to execute the corresponding first preset control command according to the triggered operation key and the corresponding pressing operation level in the state switching key operation instruction. The first preset control command includes: power on, power off, entering the quick parameter setting, entering the general parameter setting and entering the authorization setting; the second acquisition unit 30 is used to acquire the extended key operation instruction when the executed first preset control command is to enter the quick parameter setting, enter the general parameter setting or enter the authorization setting. The extended key operation instruction includes the triggering duration of the triggered operation key; the second execution unit 40 is used to execute the corresponding second preset control command according to the executed first preset control command and the triggered operation key and its triggering duration in the extended key operation instruction. The second preset control command includes: increase the control parameter value, decrease the control parameter value, switch the general parameter, switch the authorization parameter, save the current setting and exit the current operation page.

[0058] In one embodiment of the present invention, the pressing operation levels may include: long pressing a single key once, long pressing two keys once, and long pressing two keys multiple times. Among them, long pressing and short pressing can be distinguished according to the duration of the key being pressed. A pressing operation with a duration less than a preset pressing duration is a short press, and a pressing operation with a duration greater than a preset pressing duration is a long press, which can be set based on experience, for example, 5 seconds, and can also be adjusted when entering the authorization setting.

[0059] It can be understood that long pressing a single button once is the simplest operation among the three levels, so its corresponding first preset control command is the most commonly used power on, power off, and entering the quick parameter setting, which is suitable for the elderly and most users. Among them, entering the quick parameter setting may include entering the sensitivity setting and the sound volume setting; long pressing two buttons once is more complicated, so its corresponding first preset control command is the less commonly used entry into the conventional parameter setting, and after executing the first preset control command, further operation is required, such as short pressing the first button to switch the conventional parameters, in order to set specific conventional parameters, which is suitable for some users who need to adjust the conventional parameters; long pressing two buttons multiple times is the most complicated operation. Under normal circumstances, users will not make mistakes and enter the corresponding first preset control command (enter the authorization setting). Therefore, the authorized parameters (such as the minimum or maximum value of the temperature alarm, the minimum value of the concentration alarm, the maximum value of the gas tank high pressure alarm, the low battery alarm value of the battery, etc.) will not be changed by ordinary users under normal circumstances, ensuring the stable operation of the oxygen concentrator.

[0060] Specifically, the shortcut parameters may include sensitivity and sound volume. When the state switching button operation instruction is a long press of the first button, the first preset control command executed by the first execution unit 20 is power on or off. When the portable oxygen concentrator is in the power-on state, the first preset control command corresponding to the long press of the first button is power off; when the portable oxygen concentrator is in the power-off state, the first preset control command corresponding to the long press of the first button is power on; when the state switching button operation is a long press of the second button, the first preset control command executed by the first execution unit 20 is to enter the sensitivity setting; when the state switching button operation is a long press of the third button, the first preset control command executed by the first execution unit 20 is to enter the sound volume setting. When the state switching button operation is a long press of the second button and the third button, the first preset control command executed by the first execution unit 20 is to enter the general parameter setting. When the state switching button operation is a long press of the second button and the third button for multiple times, the first preset control command executed by the first execution unit 20 is to enter the authorization setting.

[0061] In one embodiment of the present invention, when the first preset control command executed by the first execution unit 20 is to enter the sensitivity setting, the extended key operation instruction obtained by the second acquisition unit 30 may be short pressing the first button, short pressing the second button, or short pressing the third button, and the second preset control commands executed by the second execution unit 40 may be saving the current settings and exiting the current operation page, increasing the control sensitivity value, and decreasing the control sensitivity value; if after entering the sensitivity setting, the second acquisition unit 30 does not obtain the extended key operation instruction within the preset time, the second execution unit 40 may automatically save the current settings and exit the current operation page.

[0062] When the first preset control command executed by the first execution unit 20 is to enter the volume setting, the extended key operation instructions acquired by the second acquisition unit 30 may be short pressing the first key, short pressing the second key, and short pressing the third key, and the second preset control commands executed by the second execution unit 40 are respectively saving the current settings and exiting the current operation page, controlling the volume value to increase, and controlling the volume value to decrease; if after entering the volume setting, the second acquisition unit 30 does not acquire the extended key operation instruction within the preset time, the second execution unit 40 may automatically save the current settings and exit the current operation page. The preset time may be a duration set according to experience or actual needs, such as 60 seconds, which is not limited in this embodiment.

[0063] When the first preset control command executed by the first execution unit 20 is to enter the general parameter setting, the extended key operation instruction obtained by the second acquisition unit 30 can be short press the first button, short press the second button, short press the third button, and long press the first button. The second preset control commands executed by the second execution unit 40 are respectively to switch general parameters, control the increase of general parameter values, control the decrease of general parameter values, save the current settings and exit the current operation page.

[0064] When the first preset control command executed by the first execution unit 20 is to enter the authorization setting, the extended key operation instruction obtained by the second acquisition unit 30 can be short press the first button, short press the second button, short press the third button, and long press the first button. The second preset control commands executed by the second execution unit 40 are to switch authorization parameters, control the increase of authorization parameter values, control the decrease of authorization parameter values, save current settings and exit the current operation page.

[0065] It can be understood that when the first preset control command executed by the first execution unit 20 is to enter the quick parameter setting, after adjusting the numerical value of the quick parameter, the user can choose to short press the first button to realize active saving, or can choose not to operate and automatically save the current setting after waiting for a preset time, which is a more convenient setting method; when the first preset control command executed by the first execution unit 20 is to enter the conventional parameter setting or enter the authorization setting, if the second acquisition unit 30 does not obtain the extended button operation instruction of long pressing the first button, the second execution unit 40 will not save the current setting, thereby avoiding erroneous operation and ensuring the safe and stable operation of the oxygen concentrator. In some other embodiments of the present invention, the extended button operation instruction may include the triggering duration and triggering number of the triggered operation button, and the extended button operation instruction corresponding to saving the current setting and exiting the current operation page may be set to long pressing the first button multiple times, long pressing multiple buttons at a time, etc., which is not limited in this embodiment.

[0066] In one embodiment of the present invention, the key control system may further include an authorization identification unit 50, which obtains an authorized key operation when the first preset control command executed by the first execution unit 20 is to enter the authorization setting, and identifies whether the authorized key operation complies with the preset authorized key operation.
