Fig. 1 is a schematic diagram of a keyboard with a sterilization function according to some embodiments of the present description. As shown in fig. 1, the keypad 110 may include at least an ultraviolet light emitting device 120.

The keypad 110 may be at least one of a mechanical keypad, a membrane keypad, and a capacitive keypad, including but not limited to. In some embodiments, the keyboard may be connected to the controller via a wired or wireless connection for transmission of information (e.g., sterilization instructions, etc.). The wireless connection mode may include a 2.4G connection mode, a bluetooth connection mode, and the like.

The keyboard receives the environmental impact in the use, accumulates dirty easily in its gap, and the frequent contact of user's hand and button also can leave the vestige on the button, if not in time clear up keyboard gap and button, leads to bacterial growing very easily, influences that the user is healthy. However, the keyboard is used as an input device of equipment such as a computer, the utilization rate is extremely high, and the keyboard is difficult to clean all the time, so that the ultraviolet light emitting device can be arranged in the keyboard, the keyboard can be sterilized when the keyboard is not cleaned completely, and the breeding of excessive bacteria is avoided.

The ultraviolet light emitting device 120 is a device that emits ultraviolet light for sterilization. Such as ultraviolet disinfection lamps. In some embodiments, the ultraviolet light emitting device 120 may include a light emitting part and a reflecting part. For more description of the light emitting component and the reflecting component of the ultraviolet light emitting device 120, refer to fig. 2 for the content of the structure of the ultraviolet light emitting device 120, and the description thereof is omitted.

In some embodiments, the placement position of the ultraviolet light emitting device 120 may include at least one of between the keycaps, inside the keycaps, below the keycaps, and outside the screen frame. The ultraviolet light emitting device 120 disposed at the above position may emit ultraviolet light to irradiate the keyboard and/or other components (e.g., mouse) to sterilize them.

The setting position of the ultraviolet light-emitting device is related to the specification of the keyboard. For example, the set position is associated with a key stroke and a key pitch. The keystroke is the distance that the key is pressed to the bottom. The key pitch refers to the distance between the same side edge of two adjacent keys on the keyboard, for example, the A key is adjacent to the S key on the keyboard, and the key pitch is the distance from the left side edge of the A key to the left side edge of the S key. Typically, the strokes are differentiated according to different keyboard types, for example, the strokes of a notebook computer are typically 1mm-2mm, while the strokes of a separate keyboard have a larger range, between 0.4mm-4 mm. The pitch of the keyboard is typically 19mm-20mm, whereas the size of one key of the keyboard is about 15mm, so that there is about 0.4mm space between two keys on the keyboard.

In some embodiments, different placement positions of the ultraviolet light emitting devices can be selected according to different key strokes and key pitches of the keyboard. For example, when the keyboard has a small key stroke (e.g., the key stroke is less than 1.5mm), and the space under or inside the keycaps is insufficient, the ultraviolet light emitting device can be disposed between the keycaps. For another example, when the keyboard has enough key stroke (e.g., the key stroke is greater than 3mm) and there is enough space under or inside the keycap, the ultraviolet light emitting device can be disposed under or inside the keycap. For another example, when the keyboard has a small key stroke and a small key pitch and cannot be used for placing the ultraviolet light emitting device (e.g., a part of a small-sized portable notebook computer), the ultraviolet light emitting device can be arranged on the outer frame of the screen, and when the computer is in a closed state, the ultraviolet light can be irradiated to the keyboard through the reflection of the screen and the scattering of the light. In some embodiments, the placement of the uv light emitting device may also include other conditions, as determined by the actual specifications of the particular visual keyboard.

In some embodiments, the keyboard 110 may include a plurality of ultraviolet light emitting devices, the number and distribution of which may be determined based on the circumstances and needs. For example, when the ultraviolet emitting device is disposed inside or below the key cap, there may be one ultraviolet emitting device for each key, or it may be disposed on some keys, for example, one ultraviolet emitting device is disposed at every other key or two keys. For another example, when the ultraviolet light emitting devices are disposed between the key caps or the outer frame of the screen, one ultraviolet light emitting device may be disposed at a certain distance, for example, 3cm or 5cm apart.

In some embodiments, the placement of the ultraviolet light emitting device 120 may also be the interior or surface of other portions of the keyboard (e.g., a base, an indicator light, a circuit board, etc.).

Compared with a sterilization module independent of a keyboard or a sterilization module capable of being stored into the keyboard through a movable structure, the method provided by some embodiments of the specification makes full use of the structure of the keycap of the keyboard to set the ultraviolet light emitting device, does not occupy additional space, makes the ultraviolet light emitting device more convenient and invisible, and realizes a sterilization function while ensuring the normal use of the keyboard by a user.

In some embodiments, the structure of the ultraviolet light emitting device 120 may include at least one of fixing, lifting, and folding. For example, the ultraviolet light emitting device 120 may be fixedly mounted on the keyboard by one or more fixing members (e.g., screws, snaps, etc.). For another example, the UV light emitting device 120 may be mounted on the keyboard via one or more lifting devices (e.g., a screw lift, a micro-scale, etc.). The lifting device can receive the command from the controller, and drive the ultraviolet light emitting device 120 to lift to a certain height (e.g., 1cm above the keyboard plane, etc.) according to the actual requirement. For another example, the ultraviolet light emitting device 120 may be mounted on the keyboard by one or more folding structures (e.g., a gear structure, a hinge structure, etc.), and unfolded when sterilization is required, and folded and retracted when sterilization is not required.

The embodiments of the present specification provide different structures of the ultraviolet light emitting device, in which the ultraviolet light emitting device fixedly installed does not involve other components for movement, and there is no loss due to repeated movement, saving space and having better stability and durability; the ultraviolet light-emitting device with the lifting structure can be lifted to a certain height according to the requirement when in use, the irradiation range is enlarged, and the sterilization effect can be better ensured; the ultraviolet light emitting device with the folding structure can be folded when not in use, and is more attractive. In different cases, the structure of the ultraviolet light emitting device can be selected according to actual requirements.

In some embodiments, the keyboard 110 may also include a controller. The controller is used for controlling and adjusting various components (e.g., the ultraviolet light emitting device 120, the power supply device, etc.) of the keyboard 110. The controller may communicate with various components of keyboard 110 and other devices or system components to obtain data, information, and/or process results and execute program instructions. In some embodiments, the controller may communicate with the sterilization control program on the mobile terminal or the computer through a network, receive instructions from the sterilization control program, or transmit data on the use of the keyboard 110. For example, the control program may send an instruction to turn on the ultraviolet light emitting device to sterilize the keyboard, and the controller may receive the instruction to turn on a switch of the ultraviolet light emitting device, so that the ultraviolet light emitting device sterilizes the keyboard. For another example, the controller may collect usage data for the keypad 110 and transmit the usage data over a network to a sterilization control program that analyzes the usage data to determine a sterilization plan. The controller can communicate with the control program on the computer through Bluetooth, wireless network, wired connection and other modes. In some embodiments, the sterilization control program may also be referred to as an application program.

In some embodiments, the controller may control and adjust the operating parameters of the ultraviolet light emitting device 120, wherein the operating parameters may include: on or off, duration of irradiation (e.g., 30 seconds, 10 minutes, etc.), intensity of irradiation (e.g., 70uW/cm ² ) And the like.

In some embodiments, the controller may control the ultraviolet light emitting device 120 to initiate sterilization.

In some embodiments, the controller may initiate sterilization based on a sterilization request command issued by the independent switch. The independent switch may include, but is not limited to, one or more of a wireless remote control button, and an independent control key provided on the keyboard. For example, the user sends a sterilization command by pressing the wireless remote control button, and the controller receives the sterilization command and controls the ultraviolet light emitting device 120 to start sterilization. For another example, the user may press a button provided on the keyboard to issue a sterilization command, and the controller may receive the sterilization command and control the ultraviolet light emitting device 120 to start sterilization.

In some embodiments, the controller may initiate sterilization based on a user pressing a function key or combination of keys on the keypad. The function key or the combination key can be a special key or a special key combination mode on the keyboard. For example, a special key may be the "C" key, and a special key combination may be "Alt" + "C" + "L". In some embodiments, the user may customize the key functions.

In some embodiments, the controller may initiate sterilization based on the opening and closing of the laptop (i.e., opening and closing of the laptop). For example, the controller detects that the notebook is closed, and after the notebook is closed, the controller starts the ultraviolet light emitting device 120 to sterilize, and meanwhile, the ultraviolet light can be more uniformly irradiated by virtue of screen reflection.

In some embodiments, the controller may be communicatively connected to the application program via a network for obtaining a sterilization plan, which may include at least one of a sterilization range, a light intensity of the ultraviolet light emitting device, a sterilization time, and a sterilization frequency.

The sterilization plan refers to a preset scheme for sterilizing a target object (e.g., a keyboard surface). The sterilization plan may be generated by an application from which the controller may retrieve the sterilization plan as needed.

In some embodiments, the controller may determine the sterilization plan based on the timing of use of the ultraviolet light emitting devices 120 and the rules of use.

In some embodiments, the usage rules of the ultraviolet light emitting devices 120 may be determined based on the interval time of usage of the ultraviolet light emitting devices 120 and/or the frequency of use of the keypad. The usage rule of the ultraviolet light emitting device 120 includes: start interval, irradiation duration, irradiation intensity. For example, when the interval time of the ultraviolet light emitting device 120 is 2 days/time, and the frequency of the keyboard is 9:00-18:00 per day, the usage rule may be that the keyboard is started 1 time every 2 days, the start time is 18:00 (e.g., 18:10) after the day, the irradiation time is 30 minutes, and the irradiation intensity is not less than 70uW/cm ² 。

In some embodiments, the timing and usage rules of the ultraviolet light emitting device 120 can be set by the user.

In some embodiments, applications may be installed on the computer, or controlled via Bluetooth + APP

For example, the keyboard can be connected to a computer through bluetooth, a data line, etc., and information such as a predetermined date and time, a time selection (e.g., 10 minutes, 20 minutes, half hour), an intensity (generally high, medium, low), etc. is automatically input in the application program, and the program sends an instruction to the controller according to the input related information.

The application may automatically send instructions to the controller when the requirements are met according to preset usage rules.

In some embodiments, the controller may obtain a time and duration of use of the keyboard, which may be used to predict the user replacement probability.

For more on predicting the user replacement probability, see fig. 6 and its associated description.

In some embodiments, the controller may control the ultraviolet light emitting device in an intelligent manner. For example, the application may determine a sterilization plan based on keyboard usage. As another example, the application may provide different sterilization plans for different users through user keying features. The controller may obtain the sterilization plan from the application program through the network to control the ultraviolet light emitting device. For more description of the control of the uv light emitting device based on the intelligent manner, reference may be made to the related description in fig. 5-6, and the description thereof is omitted here.

In some embodiments, the keyboard 110 may also include a sensing device for determining whether a user is in proximity to the keyboard. The controller may determine whether to turn on or off the ultraviolet light emitting device 120 based on the determination result.

In some embodiments, the sensing devices may include, but are not limited to, one or more of infrared human body sensing devices, pressure sensing devices, temperature sensing devices, and the like. For example, the infrared human body sensing device may be an infrared sensor, and the infrared sensor may perform non-contact temperature detection on a person and/or an object near the keyboard, collect temperature information, generate an infrared thermal imaging map of the surface of the person and/or the object, and identify whether the person is present in the map. For another example, the pressure sensing device may be a pressure sensor, and the pressure sensor may detect pressure applied to the surface of the keyboard and determine whether or not a person is present based on pressure information. For another example, the temperature sensing device may be a temperature sensor, and the temperature sensor may detect the temperature of the keyboard surface and determine whether a person is present based on the temperature information.

In some embodiments, the controller may determine to turn off one or more of the ultraviolet light emitting devices 120 based on the determination of the presence of a person. In some embodiments, the controller may determine to turn on one or more ultraviolet light emitting devices 120 based on the result of the determination that no one is present.

The method according to some embodiments of the present disclosure may determine whether a user is near the keyboard by using the sensing device, and when it is determined that the user is not near the keyboard, the controller turns on the ultraviolet light emitting device to sterilize the keyboard, thereby avoiding adverse effects of ultraviolet light on a human body as much as possible.

In some embodiments, the controller may analyze the sterilization operation in conjunction with inductive control, application control, and intelligent control.

In some embodiments, the controller may combine the sensing control with the application-based control, for example, determine whether the input based on the application is generated by the user operation through a pressure sensing device on the keyboard, and if not, not execute the control instruction corresponding to the input, thereby reducing the operation caused by the mis-touch.

In some embodiments, the controller may combine the sensing control with the intelligent control, for example, determine whether the user is using the keyboard through the infrared human body sensing device, and if the user is avoiding using the keyboard, the controller does not perform the sterilization operation, thereby avoiding inconvenience brought to the user by performing sterilization processing when the user uses the keyboard, which may affect user experience.

In some embodiments, the controller may control the ultraviolet light emitting device by a combination of a sensing device and an application program. For example, the controller receives the sterilization instruction sent by the application program, and the controller can determine that a user is near the keyboard through the pressure sensing device, and the sterilization instruction sent by the application program is the instruction sent by the user. The controller can control the ultraviolet light emitting device to sterilize according to the instruction. For another example, the controller may receive the sterilization command sent by the application program, and the controller may determine that no user is near the keyboard through the pressure sensing device, which indicates that the sterilization command sent by the application program may be an error operation. The controller may not execute the instructions described above.

In some embodiments, the controller may control the ultraviolet light emitting devices through a combination of sensing devices and intelligent control. For example, the controller receives a sterilization instruction sent by intelligent control, the controller can judge whether the user uses the keyboard at the current time through the infrared human body sensing device, and when the user uses the keyboard, the ultraviolet light emitting device does not perform sterilization; when the user does not use the keyboard, the ultraviolet light emitting device performs sterilization. For more details on the intelligent approach, reference may be made to the description in fig. 5-6, which is not repeated here.

In some embodiments of the present description, based on the combination of the sensing device and the intelligent control, the controller controls the ultraviolet light emitting device to sterilize, so as to avoid the influence on user experience caused by sterilization when the user uses the keyboard.

In some embodiments, the power supply device may be connected in series with the ultraviolet light emitting device 120 to form a circuit loop, and the power supply device may include at least one of an independent power supply device (e.g., an independent battery) and a shared power supply device (e.g., a battery built in a notebook computer). The power supply device can provide a safe voltage not higher than 36V for the keyboard.

In some embodiments, the controller may determine the remaining power of the independent power supply and the common power supply. In some embodiments, the application may select different sterilization times or adjust the sterilization strategy, e.g., shorten the sterilization time, stop the sterilization activity, etc., depending on the remaining capacity of the individual power supply devices or the common power supply device.

In some embodiments, an atmosphere lamp is also connected to the power supply. When sterilization is required, the ultraviolet light emitting device 120 is operated, and the atmosphere lamp may be operated at other times.

The method according to some embodiments of the present description adjusts the sterilization strategy in time by judging the battery usage, adapts to various usage scenarios, and can avoid not only that the independent power supply battery cannot sterilize due to insufficient power, but also that the computer cannot support sterilization due to too low power when the power is supplied in common.

In some embodiments, the keyboard 110 further includes a reminder module for issuing a reminder to the user in a manner including, but not limited to, an indicator light, a ring tone, a screen pop-up, and the like.

In some embodiments, the prompting module may be used to prompt the user to sterilize when the user has changed or is likely to have changed.

In some embodiments, the prompting module is further configured to prompt the user to sterilize when the user replacement probability is greater than a preset threshold.

For further description of prompting the user to sterilize, reference may be made to fig. 5, 6 and their associated description.

In some embodiments, a prompt module may be used to prompt the user to place the mouse at a specified location. For more on prompting the user to place the mouse at a prescribed location, see FIG. 8 and its associated description.

It should be noted that the keyboard with the sterilization function is provided for illustrative purposes only and is not intended to limit the scope of the present application. It will be apparent to those skilled in the art that various modifications and variations can be made in light of the description of the present application. For example, the keyboard with the sterilization function may further include a mouse, a base, and the like. However, such changes and modifications do not depart from the scope of the present application.

FIG. 2 is a schematic view of an ultraviolet light emitting device shown according to some embodiments herein. As shown in fig. 2, the ultraviolet light emitting device 200 may include a light emitting part 210 and a reflecting part 220.

The light emitting part 210 refers to a part capable of emitting ultraviolet rays. In some embodiments, the light emitting component may be an ultraviolet light tube or a light bead. For example, UVA lamps (320-420 nm), UVB lamps (275-320 nm), UVC lamps (200-275 nm) and UVD lamps (100-200nm) are divided according to different wavelengths. Because different bacteria species have different absorption peaks of ultraviolet rays, ultraviolet sterilization time and wavelength required for ultraviolet sterilization of different microorganisms are different. For example, the maximum absorption wavelength of Escherichia coli is 265nm, and the maximum absorption wavelengths of Cryptosporidium and bacteriophage are 261nm and 271nm, respectively, so that the light-emitting component may include at least one band of ultraviolet light to ensure sufficient sterilization of common microorganisms such as bacteria and viruses.

In some embodiments, the light emitting component 210 may also be combined with an atmosphere light of the keyboard 110, i.e., the atmosphere light may emit two different types of light, the LED light of the atmosphere light being operative to emit the atmosphere light when the keyboard is in the use state, and the ultraviolet light being operative to emit the ultraviolet light to sterilize when the keyboard is in the sterilization state.

The reflecting member 220 is a member that reflects ultraviolet rays and increases the irradiation range of the ultraviolet rays. In some embodiments, the structure of the reflection part 220 on the keypad may include a plurality of unit reflection regions, each of which may have a concave or convex reflection plate, wherein the reflection plate may be a reflection plate made of an inorganic material and formed of a porous material. The reflective part 220 may increase an irradiation area of the light emitting part 210 and make the light irradiation more uniform.

In some embodiments, the reflecting member 220 is disposed around the light emitting member 210 near the light source, thereby forming a semi-wrapped state in which the ultraviolet light emitted from the light emitting member can be reflected to different angles.

In some embodiments, the reflective member 220 may also be disposed on the keypad. For example, the reflective component may be disposed at an edge of the keycaps, at a gap between the keycaps, or the like.

In some embodiments, the reflective member 220 may be disposed on a screen of a notebook computer. The reflective member 220 on the screen may include a screen having a high reflectivity (e.g., 10%), a screen protective film, and the like. Through the reflection part who sets up on the screen, can increase reflection part's area, when notebook computer is in the closed condition, can reflect the ultraviolet ray of giving out of luminous component 210, make the ultraviolet ray more abundant shine whole keyboard region, obtain better bactericidal effect.

Fig. 3 is a schematic diagram of a keyboard and mouse device with a sterilization function according to some embodiments of the present disclosure. As shown in fig. 3, the keyboard and mouse apparatus 300 may include a keyboard 330, a mouse 310, an ultraviolet light emitting device 320, and a controller.

The mouse 310 may be at least one of a mechanical mouse, an optical mouse, and an optical mouse, including but not limited to. The mouse 310 may be connected to the controller by wire or wirelessly for information transmission (e.g., sterilization instructions). The wireless connection mode may include 27Mhz connection, 2.4G connection, and bluetooth connection.

In some embodiments, a user may issue a sterilization request command via the mouse 310. The sterilization request command may include a request to sterilize the mouse 310, a request to sterilize the keyboard 330, a request to sterilize other devices (e.g., a display screen), and the like.

In some embodiments, the user may click the mouse 310 to issue the sterilization request command in different ways. In some embodiments, different mouse 310 click modes corresponding to different sterilization request triggering instructions are stored in the controller, and when the application program runs, different sterilization plans can be executed by operating the mouse. For example, a double click of the left button corresponds to a request to sterilize the mouse 310, a right click corresponds to a request to sterilize the keyboard 330, a single click of the left or right corresponds to a display screen, and the like. The click mode of the mouse 310 may be executed as a control command, and the execution result is the implementation of the sterilization operation. For example, when the user clicks the mouse 310 in a left-click manner, the controller receives an instruction requesting sterilization of the mouse 310, and then issues a control instruction to the sterilization device (e.g., the ultraviolet light emitting device) to sterilize the mouse 310. In some embodiments, the mouse 310 click pattern may be set by default by the controller or customized by the user according to personal preferences.

In some embodiments, the user may issue a sterilization request command by clicking a corresponding functional area on the computer desktop through the mouse 310. For example, the functional area may be a function button in the sterilization application (e.g., home page, popup, option bar after icon right key) corresponding to "sterilization". The functional area may also be a certain blank area of the desktop that is set by the controller by default or by the user by customization according to personal preferences.

In some embodiments, the mouse 310 is provided with an electro-optical scanning unit for determining the relative position of the keyboard 330 and the mouse 310.

The photoelectric scanning unit is a sensing device that converts an optical signal into an electrical signal using a photoelectric scanning method. Such as a photoelectric position sensor, a slot type photoelectric sensor, etc.

In some embodiments, the electro-optical scanning unit may determine the relative position of the keyboard and mouse based on an image of the user's hand. For more description about determining the relative position of the keyboard 330 and the mouse 310 based on the image of the hand of the user, refer to fig. 9 for the content of determining whether the mouse 310 is placed at the predetermined position, and the description thereof is omitted here.

In some embodiments, the keyboard and mouse device 300 is provided with an ultraviolet light emitting device 320.

In some embodiments, the ultraviolet light emitting device 320 is disposed in the mouse 310, and the ultraviolet light emitting device 320 may be used to sterilize one or more components of the keyboard and mouse apparatus 300 (e.g., the keyboard 330, the mouse 310, etc.).

In some embodiments, an ultraviolet light emitting device disposed in the mouse 310 may sterilize the keyboard 330. For further description of the sterilization of the keyboard 330 by the ultraviolet light emitting device disposed in the mouse 310, reference may be made to fig. 8 for a key mouse device sterilization method, and further description is omitted here.

In some embodiments, the mouse 310 may also sterilize the mouse 310 itself. For example, a reflective member is mounted outside the ultraviolet device inside the mouse 310, and a photocatalyst layer is sprayed on the outer surface of the mouse 310. While the ultraviolet light emitting device 320 of the mouse 310 sterilizes other devices (e.g., the keyboard 330), the mouse 310 itself may also be sterilized.

In some embodiments, the ultraviolet light emitting device may be disposed on the keyboard 330, and the keyboard 330 may sterilize the mouse 310 through the ultraviolet light emitting device. For further description of the sterilization of the mouse 310 by the ultraviolet light emitting device disposed in the keyboard 330, reference may be made to fig. 8 for a description of a key mouse device sterilization method, which is not described herein again.

For more details of the ultraviolet light emitting device and its arrangement, reference may be made to the related description in fig. 1 and fig. 2, and details thereof are not repeated here.

The keyboard 330 may be connected to various components of the keyboard and mouse apparatus 300 (e.g., the controller, the mouse 310, the ultraviolet light emitting device 320, etc.) in a wired or wireless manner, and a user may issue an instruction (e.g., a sterilization instruction, etc.) by clicking a key of the keyboard 330. For more description of the keyboard 330, reference may be made to the aforementioned content of the keyboard 110 in fig. 1, and further description is omitted here.

The controller can control and regulate the components of the keyboard and mouse device 300 (such as the keyboard 330, the mouse 310, the ultraviolet light emitting device 320 and the like) to complete the sterilization operation. In some embodiments, the controller may be a built-in control unit of the computer and/or components of the keyboard and mouse device 300 (e.g., keyboard, mouse).

In some embodiments, the controller is in communication connection with the application program through a network, and is configured to receive a determination from the application program whether the mouse is placed at a predetermined position, and in response to the mouse being placed at the predetermined position, the controller controls the ultraviolet light emitting device to turn on to start executing the sterilization plan.

For more description of the controller, reference may be made to the content of the controller in fig. 1, which is not described herein again.

FIG. 4 is an exemplary flow diagram of a keyboard sterilization method, according to some embodiments described herein. As shown in fig. 4, the process 400 includes the following steps. In some embodiments, the process 400 may be performed by a controller.

Step 410, obtaining the keyboard use condition.

Keyboard usage may refer to keyboard usage data relating to a keyboard. In some embodiments, the keyboard usage may include at least one of a usage status of the keyboard, a keyboard usage time, and the like. The use state of the keyboard may refer to a state regarding whether the keyboard is used by the user at different times. For example, the use state of the keyboard may include a use state, a non-use state, and the like. The keyboard age may refer to the length of time the user uses the keyboard, e.g., 1 hour, 3 hours, 5 hours, etc. The keyboard usage time may include how many hours of a day the keyboard is used, the time interval between two uses of the keyboard, etc.

In some embodiments, the controller may obtain keyboard usage over a network. For example, the controller may be connected to the application program through a network. The keyboard use condition is stored in the application program, and the controller can acquire the keyboard use condition in the application program.

In step 420, key data of the user is obtained.

User keystroke data may refer to information about the user's use of different keys. The keyboard is provided with a plurality of keys, and when the keyboard is used by a user, the use of each key is different. The use of keyboards by different users also varies. In some embodiments, the user keystroke data may comprise at least one of user input, user keystroke characteristics, and the like. The user input may refer to key information of the user, for example, the user presses a function key or a combination key indicating sterilization, and further, for example, the user presses an on-off key indicating sterilization, or the like. The key characteristics of the user may include a key sequence and a key interval sequence of the user, and may reflect key habits of different users, such as key frequency, common key range, and the like. The user key characteristics may also include the force with which the user strikes the keyboard, etc. For more description of the user's key press features, see the relevant contents in step 510.

In some embodiments, the controller may obtain the user keystroke data based on a network. For example, the controller may be connected to the application program through a network. The application program stores user key data, and the controller can acquire the user key data in the application program.

And step 430, determining a sterilization plan based on the keyboard use condition and the key pressing data of the user.

The sterilization plan may refer to specific information about sterilization. In some embodiments, the sterilization plan includes at least one of a sterilization range, a light emission intensity of the ultraviolet light emitting device, and a sterilization time. The sterilization range may refer to a region sterilized in the keypad. For example, the sterilization range may include a full range of the keypad, a range of function keys, a range of main keypad, a range of control keys, a range of number keys, etc. The light emission intensity of the ultraviolet light emitting device can be classified into low, medium, high, or alternative intensity ranges, e.g., 70uW/cm ² ～180uW/cm ² . The sterilization time may include a specific time point of sterilization, a sterilization time period, a sterilization frequency, a sterilization time interval, and the like. For example, the sterilization time point is 13:00, the sterilization time period is 20 minutes, and the sterilization frequency is once per 2 hours.

In some embodiments, different keyboard ranges may be sterilized by controlling the range in which the ultraviolet light emitting device emits light. In some cases, the keyboard can be sterilized as necessary on the premise of ensuring the power consumption of the computer by adopting a strategy of sterilizing partial areas of the keyboard. For example, when the ultraviolet light emitting device and the computer share the power supply, the user has a sterilization requirement, but at the same time, to ensure the endurance of the computer, the user can sterilize a part of the keyboard area, for example, only the key range released by the user is sterilized, or the key area with the user contact times/contact duration exceeding the threshold value is sterilized, and the whole keyboard area is sterilized when the electric quantity is sufficiently supplied, so that the power consumption is controlled, and the sterilization effectiveness is ensured.

In some embodiments, the sterilization plan may be determined in a variety of ways. In some embodiments, the sterilization plan may be determined based on keyboard usage and user keystroke data. For example, the sterilization time may be set to a time when the user does not use the keypad. For another example, the sterilization range may be set in a partial range of a keyboard (e.g., a main keyboard range) that is commonly used by the user. For example, the light emission intensity of the ultraviolet light emitting device in a partial range of the keyboard that is commonly used by the user may be set to be high.

In some embodiments, the sterilization plan may be determined by querying a preset relationship table based on keyboard usage and user keystroke data. The preset relation table is determined according to the data of the keyboard used by a user, such as the use duration of the keyboard, the common use range of the keyboard and the like, and is related to the luminous intensity, the luminous time and the disinfection range of the ultraviolet light-emitting device, wherein the data represent parameters capable of achieving effective sterilization under different keyboard use conditions. The preset relation table can be a preset standard, and data in the preset relation table can be inquired through an application program and sent to the controller as a sterilization plan to control the ultraviolet sterilization device to start sterilization.

In some embodiments, the controller may determine the light intensity and the sterilization time based on the keyboard usage time. The luminous intensity is positively correlated with the keyboard service time, and the sterilization time is positively correlated with the keyboard service time. For example, the keyboard usage time is 1 hour, 2 hours, 3 hours, etc., respectively, and the light intensity corresponding to the keyboard usage time may be increased, such as the corresponding light intensity is low, medium, and high, respectively; the keyboard use time can be increased gradually, for example, the corresponding sterilization time is 10 minutes, 20 minutes and 30 minutes respectively.

In some embodiments of the present disclosure, the controller may determine a sterilization plan based on actual usage of the keyboard, for example, in a single sterilization plan, the same sterilization time applies stronger light intensity to a keyboard with high usage frequency, so as to ensure that the commonly used keys can be sufficiently sterilized, thereby obtaining a better sterilization effect.

In some embodiments, the application may determine the sterilization scope based on user key characteristics. For example, the application program may determine the key range with high contact frequency of the user through the key features of the user, and further determine the key range with high contact frequency of the user as a sterilization range, or perform key sterilization on the key pad range with high contact frequency, for example, use a higher light emitting intensity.

In some embodiments of this description, the controller can be based on the keyboard in-service use condition, and to the key range key degerming that contact frequency is high, guaranteed the accurate degree of degerming, can have more corresponding degerming.

In some embodiments, the sterilization time may also include a time interval for sterilization. The time interval of sterilization may refer to how long the sterilization is performed. For example, the time interval for sterilization may be 60 minutes, 110 minutes, etc.

In some embodiments, the controller may control the time interval of sterilization of the ultraviolet light emitting device according to the keyboard use time. For example, the time for acquiring the keyboard use time of the user through the application program is generally 09:00-10:30, 10:50-12:00, and the controller may control the sterilization time interval to be 110 minutes according to the keyboard use time, and the sterilization time may be 08:50 and 10: 40. For another example, if the application program obtains that the user normally uses the keyboard between 09:00 and 18:00 and has no use record between 20:00 and 8:00 of the next day, the time interval of sterilization can be determined to be 24 hours, and the sterilization time is set between 20:00 and 8:00 of the next day.

In some embodiments of the present description, the controller controls a time interval of sterilization of the ultraviolet light emitting device according to a keyboard use time. The sterilization can be carried out in the time period when the user does not use the keyboard, the time for the user to use the keyboard is not occupied, and the user experience is further improved.

In some embodiments, a sterilization plan including at least one of a sterilization range, a light emission intensity of the ultraviolet light emitting device, and a sterilization time may be determined according to the use condition of the keyboard and mouse apparatus and the user key data. The use condition of the keyboard and mouse device comprises the use condition of a keyboard and the use condition of a mouse in the keyboard and mouse device. For example, the light emission intensity and the light emission time of the ultraviolet light emitting device are determined according to the use time of the keyboard and/or the mouse, and the range of the key sterilization is determined according to the use range of the keyboard.

In step 440, the use status of the keyboard is determined, and the use status may include a use status and a non-use status.

In some embodiments, the controller may determine the use status of the keyboard through the sensing device. If the sensing device cannot sense the existence of the user within the preset distance range, the controller can judge that the use state of the keyboard is a non-use state. For example, the preset range is 1 meter, the controller can sense whether a user exists within 1 meter through the infrared human body sensing device, and if the user does not exist, the controller can judge that the use state of the keyboard is a non-use state; if the presence of the user is sensed, the controller may determine that the keyboard is in use.

In some embodiments, the controller may also determine whether the keyboard is in a use state through other types of sensing devices, for example, a pressure sensing device, a temperature sensing device, and the like, which can be described in relation to fig. 1.

In some embodiments, the controller may determine the use state of the keyboard by a user's operation. If the user performs the preset operation, it may be judged that the keyboard enters the non-use state. In some embodiments, the preset operation may be an operation set in advance. For example, sterilization is performed at a certain time (e.g., 12 o' clock sterilization), when a certain condition is satisfied (e.g., 2 hours of keyboard use). When the controller reminds the user whether to execute the preset operation, the user determines to execute the preset operation, the user agrees to sterilize at the current moment, the keyboard is paused, and the controller can judge that the keyboard is in a non-use state. When the controller reminds the user whether to execute the preset operation, the user determines not to execute the preset operation, the user does not agree with the current time to sterilize, the keyboard is required to be used, and the controller can judge that the use state of the keyboard is the use state. In some embodiments, the preset operation may be performed by pressing a switch for controlling the start of sterilization by a user, or pressing a function key or a combination key on the keyboard for controlling the start of sterilization, and when the user presses the switch or the key, it is determined that the user is no longer using the keyboard, and the controller controls the ultraviolet light emitting device to start sterilization. The sterilization may be started after a preset time (e.g., 5 seconds, 10 seconds, etc.) is delayed after the button is pressed, so as to ensure that the user leaves.

In some embodiments, the controller may determine the location of the user via the sensing device, discontinue sterilization when the user is near the keyboard on which the sterilization plan is being executed, and resume sterilization when the user leaves.

In some embodiments, in response to the keyboard being in a non-use state, the controller may control the ultraviolet light emitting device to turn on to start executing the sterilization plan.

In some embodiments, a prompt may be issued to the user by the application in response to the sterilization plan being executed. For example, a word of "sterilization completion" is displayed on the screen, a voice prompt is issued, and the like. In some embodiments, in response to the sterilization plan being executed, the application program may also ask the user whether to execute the sterilization plan again for deep sterilization.

In some embodiments of the present disclosure, when it is determined that the user is not near the keyboard, the controller turns on the ultraviolet light emitting device to sterilize the keyboard, thereby avoiding adverse effects of ultraviolet light on the human body as much as possible.

In some embodiments of the present description, a more targeted sterilization plan is formulated according to the keyboard usage, the user key data, and the like, so that the sterilization efficiency can be better ensured.

. It should be noted that the above description related to the flow 400 is only for illustration and description, and does not limit the applicable scope of the present specification. Various modifications and changes to flow 400 will be apparent to those skilled in the art in light of this description. However, such modifications and variations are intended to be within the scope of the present description. For example, step 420 is executed to obtain the user key data, and then step 410 is executed to obtain the keyboard usage; for another example, step 440 is performed to determine the keyboard usage status, and step 430 is performed to determine the sterilization plan.

FIG. 5 is an exemplary flow chart of another keyboard sterilization method according to some embodiments described herein. As shown in fig. 5, the process 500 includes the following steps. In some embodiments, the process 500 may be performed by a controller.

And step 510, acquiring the key characteristics of the user, and judging the user according to the key characteristics of the user.

In some embodiments, the user key characteristics may include a key sequence and a key interval sequence. In some embodiments, the sequence of key presses is also referred to as a sequence of taps and the sequence of key press intervals is also referred to as a sequence of interval times.

In some embodiments, the controller may obtain a sequence of taps for a user to tap the keyboard. Due to the fact that different users have different familiarity and knocking habits on the keyboard, the knocking sequences corresponding to different users are different. The tapping sequence may represent what the user taps the keyboard in turn, e.g. tapping sequence 1 as "nihao". The tapping sequence of a user tapping the keyboard may comprise a plurality of sets of tapping sequences. Different groups of tapping sequences can be separated according to certain preset rules. For example, the preset rule is that when the user taps the space bar, the end of the current tap sequence and the beginning of the next set of tap sequences are determined. In this manner, the controller may obtain each set of stroke sequences separated by a space key. Based on the sets of tapping sequences, the controller may obtain a corresponding internal interval time sequence.

In some embodiments, the controller may represent the user key data by a sequence of taps, e.g., the sequence of taps (S1, S2, S3, S4, S5, S6. Different elements in the stroke sequence may represent user keystroke data between two strokes of the spacebar. Illustratively, S1 represents user key data before the 1 st stroke of the space bar by the user; s2 represents the user' S key data between the 1 st and 2 nd space key strokes by the user; sn represents the user key data between the n-1 st and n-th times of hitting the space bar by the user.

In some embodiments, the controller may obtain the interval elapsed time sequence based on a key press time interval of the user. The interval time sequence may represent the time interval during which the user hits different keys. For example, the interval time series (T1, T2, T3, T4, T5, T6,. gtn) is the interval time series corresponding to the tap series. Different elements in the interval-time sequence may represent each key press time interval in each sequence of strokes separated by a space bar by the user. Illustratively, T1 represents the key press time interval of the user key data S1 before the 1 st space key stroke by the user; t2 represents the key press time interval of the user key data S2 between the 1 st and 2 nd space key strokes by the user; tn represents the key press time interval of the user key data Sn between the n-1 st and nth space key strokes by the user.

In some embodiments, the controller may obtain one or more tap sequences having a frequency greater than a frequency threshold based on the frequencies corresponding to the plurality of tap sequences. The frequency corresponding to the sequence of taps may refer to how fast the user presses the keys. The frequency threshold may refer to a maximum value of the time interval of the time sequence corresponding to an interval of a particular tapping sequence. For example, the frequency threshold of 1 second represents that each value in the interval time sequence corresponding to the tapping sequence is less than 1. The controller may obtain one or more tapping sequences with a frequency less than a frequency threshold 1 based on the frequencies corresponding to the multiple tapping sequences. In some embodiments, the controller may center the amount of orientation for the sequence of taps having a frequency less than 1. For example, the vector centers of the tapping sequences with frequencies less than the frequency threshold 1 are vector center a, vector center B, vector center C, and vector center D, respectively.

In some embodiments, the controller may obtain newly entered user keystroke data by the user after a longer time interval (e.g., 30 seconds), the newly entered user keystroke data corresponding to a new sequence of taps. The controller may obtain a vector center (e.g., vector center E) corresponding to the new tap sequence. The controller may confirm whether vector center E is consistent with vector center a, vector center B, vector center C, and vector center D, indicating that the user entering the new tap sequence may not be the same user as the user previously entering the tap sequence and that the user has changed if vector center E is inconsistent with vector center a through vector center D.

In some embodiments of the present description, by comparing differences between vector centers corresponding to multiple types of tapping sequences greater than a frequency threshold and vector centers corresponding to tapping sequences newly input by a user after a long time interval, a user using a keyboard can be determined according to differences in familiarity, tapping habits, and the like reflected by user key data, different sterilization plans are provided for different users, targeted sterilization can be performed according to habits of the user actually using the keyboard, and the effectiveness of sterilization is ensured.

Step 520, determining a sterilization plan for the current user according to the key features of the current user.

In some embodiments, the application may provide different sterilization plans based on the keystroke data of different users. For example, different sterilization durations and sterilization intensities are determined according to the duration of using the keyboard by different users, and the range of performing sterilization with emphasis is determined according to the common range of using the keyboard by different users.

In some embodiments, the sterilization plan may be determined by looking up a preset relationship table according to key data of different users. Further details of determining the sterilization plan by looking up the predetermined relationship table can be found in step 430 and its associated description.

In some embodiments, the user determined in step 510 and the sterilization plan corresponding to the user can be stored in the computer or the mobile terminal where the application is located through the application, and when the user uses the keyboard again, the user can directly call the sterilization plan after finishing using the keyboard, so as to optimize the processing flow of the application and provide the sterilization plan more efficiently.

In some embodiments, the controller may process the user keystroke data based on a control sterilization model to determine a sterilization plan.

The control sterilization model may be used to determine a sterilization plan. In some embodiments, the input controlling the sterilization model may include a key feature of the user and the output may include a sterilization plan. The key characteristics of the user at least comprise a key sequence and a key interval sequence of the user.

In some embodiments, the input for controlling the sterilization model may further include a user's key force, and the key force data may be obtained by a pressure sensor provided on the keyboard.

In some embodiments, the control sterilization model may include a feature determination layer and a plan determination layer. The output of the feature determination layer may be used as an input to the schedule determination layer and the output of the schedule determination layer as an output to control the sterilization model.

The feature determination layer may be used to determine a key feature vector. The input of the feature determination layer may include key features of the user, the output of the feature determination layer may include key feature vectors, and the key feature vectors may be used to characterize features of the user related to key press habits, such as a frequently used key range of the user, a key press frequency of the user, and the like.

The plan determination layer may be used to determine a sterilization plan. The input to the characterization layer may include case feature vectors and the output from the characterization layer may include a sterilization plan, which may include at least one of sterilization range, light intensity of the ultraviolet light emitting devices, and sterilization time. In some embodiments, the plan determination layer may be a Convolutional Neural Network (CNN), Deep Neural Network (DNN), or the like model.

In some embodiments, the control sterilization model may be obtained by joint training of the feature determination layer and the plan determination layer based on a plurality of training samples and labels.

In some embodiments, the training samples of the sterilization control model may include historical user key features of different users. The label can be historical sterilization plans corresponding to different users, and the label can be obtained through historical sterilization data or obtained through manual labeling.

In some embodiments, the key characteristic of the user is input into an initial characteristic determining layer of an initial control sterilization model to obtain an initial key characteristic vector, the initial key characteristic vector is input into an initial plan determining layer of the initial control sterilization model to obtain an initial sterilization plan, a loss function is constructed based on the initial sterilization plan and a historical sterilization plan, parameters of the characteristic determining layer and the plan determining layer are updated through training, and when the trained initial data obtaining model and the trained initial plan determining model meet preset conditions, the training is finished to obtain a trained control sterilization model.

In some embodiments of the present description, different sterilization plans are provided for different users, and sterilization can be performed specifically according to different habits of different users. In some embodiments of the present description, the sterilization model is controlled to process the user key data to determine a corresponding sterilization plan, and different sterilization plans may be determined according to different habits of different users.

And step 530, carrying out sterilization prompt when the user is replaced.

In some cases, the same keyboard, keyboard and mouse device, or computer may be frequently changed for the user in use. For example, a computer room in a school, a public computer in a library, etc., may be used by different users over time. Therefore, it is necessary to sterilize or prompt the user to sterilize the device in time when the user changes the device, so as to ensure that the user can use the sterilized device.

The sterilization prompt may refer to a prompt to remind the user to perform sterilization. The sterilization prompt may be provided by means of an indicator light, a ring tone, a screen pop-up window, etc.

In some embodiments, the application may prompt for a kill when it determines that a user using the keyboard has changed. For example, when it is determined that a user using the keyboard has changed, the controller may prompt the user whether to perform sterilization through a screen pop-up window, and the user may select whether to perform sterilization according to the screen pop-up window prompt.

In some embodiments, the application may determine whether the user has changed by the user's key feature. For example, when a user's key sequence or key interval sequence is changed, the user replacement may be judged.

In some embodiments, the application may predict whether the user will change through the sterilization prediction model, and sterilize or prompt the user to sterilize if the user will change with a high probability.

For more on the model of prediction of sterilization, see fig. 6 and its associated description.

FIG. 6 is a schematic diagram of a sterilization prediction model, according to some embodiments of the present description. As shown in FIG. 6, the execution and training 600 of the sterilization prediction model includes at least the following.

In some embodiments, the application may predict the user replacement probability and either sterilize ahead of time or prompt the user to sterilize when there is a high probability that the user will be replaced.

In some embodiments, the application may include, via the predictive model of sterilization: the user replacement probability 630 is determined by the sterilization predictive model 620 based on the keyboard usage time 610-1 and the keyboard usage duration 610-2, where the sterilization predictive model 620 is trained from tagged historical data 621-1. The keyboard use time refers to a time period for using the keyboard, for example, 08:00-09:00, and the keyboard use duration refers to a time period for using the keyboard, for example, 1 hour.

In some embodiments, the user replacement probability may correspond to the probability of replacing a user at one or more points in time. The application program can determine whether sterilization is performed before one or more time points according to the probability of replacing the user at one or more time points. For example, the application program determines the probability of replacing the user at the time point of 10:00 as 20% through a sterilization prediction model; the probability of replacing users is 60 percent at 13: 00; the probability of a 16:00 replacement user is 80%. The probability of replacing users at the time points 13:00 and 16:00 is high, and the application program can determine that the sterilization is performed before the time points 13:00 and 16:00, and send a sterilization instruction to the controller to control the ultraviolet light emitting device to be started for sterilization.

The sterilization prediction model 620 may be used to predict the probability of a user replacement based on keyboard usage time and keyboard usage duration. In some embodiments, the predictive model of sterilization may be a Deep Neural network model (DNN).

In some embodiments, the input of the sterilization prediction model may include keyboard usage time and keyboard usage duration obtained by the application, and the output may be a probability of user replacement. In some embodiments, the probability of user replacement may be represented by a value, such as a value of 0-1 representing the probability of user replacement from small to large, and when the probability of user replacement is greater than a preset threshold, user replacement may be determined.

In some embodiments, the sterilization prediction model may also be other models capable of determining the replacement probability of the user, which may be determined according to actual situations.

In some embodiments, the sterilization prediction model may be derived from a plurality of labeled training samples. For example, a plurality of training samples with labels may be input into the initial sterilization prediction model 621, a loss function may be constructed from the labels and the results of the initial sterilization prediction model 621, and the parameters of the initial sterilization prediction model 621 may be updated based on iterations of the loss function. And finishing model training when the loss function of the initial sterilization prediction model 621 meets a preset condition to obtain a trained sterilization prediction model 620. The preset condition may be that the loss function converges, the number of iterations reaches a threshold, and the like.

In some embodiments, the training samples may include historical data 621-1, which historical data 621-1 may include historical user keystroke data and historical keyboard usage.

In some embodiments, the trained labels may include historical user replacement probabilities 621-2, which may be obtained from historical processing data, or may be obtained by manual labeling, as determined by actual needs.

In some embodiments, the historical data and historical user replacement probabilities may also be obtained by calling from a storage device, a network.

In some embodiments of the present specification, the probability of replacing a user is determined by processing the key characteristics of the user through the sterilization prediction model, so that it can be ensured that the keyboard used by each user is a sterilized keyboard.

FIG. 7 is an exemplary flow chart of a method of adjusting a sterilization plan, according to some embodiments described herein. As shown in fig. 7, the process 700 includes the following steps. In some embodiments, flow 700 may be performed by an application.

And step 710, acquiring the use state of the power supply device, wherein the use state comprises that the ultraviolet light emitting device and a computer share the power supply device or use an independent power supply device and is acquired through communication with an application program.

In some embodiments, the controller may obtain the usage status of the power supply by communicating with an application. For example, the controller may communicate with the application program via the network to obtain whether the power supply device is used by the ultraviolet light emitting device and the computer.

Step 720, when the power supply device shared by the ultraviolet light emitting device and the computer is determined, the sterilization plan is adjusted according to the remaining power of the shared power supply device.

In some embodiments, when determining that the power supply device is shared by the ultraviolet light emitting device and the computer, the controller may adjust the sterilization plan according to the remaining power of the shared power supply device. For example, when the remaining capacity of the common power supply device is less than the first threshold value, the sterilization plan is adjusted. The first threshold may refer to a value (e.g., 40%) of the remaining amount of power of the common power supply. When the remaining capacity of the common power supply device is less than 40%, the sterilization plan can be adjusted from sterilization plan A (e.g., sterilization time: 10 minutes, sterilization range: full range of keyboard, light emission intensity of ultraviolet light emitting device: high) to sterilization plan B (e.g., sterilization time: 5 minutes, sterilization range: main keyboard range, light emission intensity of ultraviolet light emitting device: medium), and the power consumption of the ultraviolet light emitting device is reduced. For another example, when the remaining capacity of the common power supply device is less than the second threshold value, the sterilization plan is suspended. The second threshold may refer to a certain value (e.g., 20%) of the remaining power of the common power supply. When the residual capacity of the shared power supply device is less than 20%, the controller can suspend the sterilization plan, and the normal use of the computer is preferentially ensured.

In some embodiments of the present disclosure, the sterilization plan is adjusted according to the remaining power of the common power supply device, and the sterilization plan can be adjusted when the power of the power supply device is insufficient, so as to reduce the power consumption of the ultraviolet light emitting device, and preferentially ensure the normal use of the computer.

In some embodiments, the keyboard may also be a stand-alone keyboard, and the ultraviolet light emitting device is powered by the keyboard's own power supply. For details regarding the power control of the independent keyboard, reference is made to fig. 10 and its associated description.

Fig. 8 is a flow diagram illustrating a method of sterilizing a keyboard and mouse device according to some embodiments of the present disclosure. As shown in fig. 8, the process 800 includes the following steps:

and 810, acquiring the use condition of the keyboard and mouse device, and prompting a user to place a mouse at a specified position when the keyboard and mouse device enters a non-use state. In some embodiments, step 810 may be performed by an application.

In some embodiments, when it is determined that the keyboard or keyboard and mouse device is not in use, the user may be prompted to place the mouse in a prescribed position.

The predetermined position is a position where the mouse can be placed to effectively sterilize the mouse and/or the keyboard. E.g., the left side of the keyboard, the surface of the keyboard, etc.

In some embodiments, the prescribed location may be beside the keyboard, e.g., the right side of the keyboard, the side of the keyboard near the user, etc. In some embodiments, the defined position may also be any position on the surface of the keyboard, and the mouse may be inverted over the keyboard. In some embodiments, the defined position of the mouse may also be other positions determined according to actual requirements (e.g., actual sterilization effect, etc.).

In some embodiments, the application may generate a prompt message for prompting the user to place the mouse at a specified location. The form of the prompt message includes but is not limited to one or more of text popup, graphical illustration, voice broadcast, and flashing of indicator light. For example, the application may generate a graphic or animation for prompting the user to place a mouse at a prescribed location on the keyboard, and present the graphic or animation on the display screen for prompting the user. For another example, an indicator light may be provided at a predetermined position on the keyboard to indicate a predetermined position of the mouse on the keyboard. For example, when it is necessary to sterilize the mouse and/or the keyboard, an indicator lamp corresponding to a prescribed position is turned on to prompt the user to place it there.

In some embodiments, when the mouse is sterilized, since the most commonly used parts of the mouse are the buttons and the wheel, in order to effectively sterilize the parts of the mouse, the controller may prompt the user to turn the mouse upside down on the keyboard.

Step 820, determining whether the mouse is placed at the predetermined position. In some embodiments, step 820 may be performed by the application program through the electro-optical scanning unit.

In some embodiments, the controller may determine whether the mouse is placed in a prescribed position. In particular, the controller may be determined by means of a photoelectric scan. For more description of the photoelectric scanning, refer to fig. 9 for the content of the photoelectric scanning, and the description thereof is omitted here.

And 830, responding to the judgment result that the mouse is placed at the specified position, and starting to execute a sterilization plan. In some embodiments, step 830 may be performed by a controller.

In some embodiments, when the application program determines that the mouse is placed at the specified position, a sterilization instruction can be sent to the controller to control the ultraviolet light emitting device arranged on the keyboard to be turned on to start sterilization.

In some embodiments, the ultraviolet light emitting device has a lifting unit, which can be lifted up to a certain height to sterilize the mouse.

The lifting unit is a device for driving the ultraviolet light emitting device to move up and down. Such as a screw jack, a micro-telescope, etc. In some embodiments, the uv light emitting device may be driven by the lifting unit to be lifted to a certain height (e.g., 5cm above the plane of the keyboard, etc.) to perform uv sterilization on the mouse. In some embodiments, the ultraviolet light emitting device may be driven by the lifting unit to move continuously (e.g., lift reciprocally, lift gradually, lower gradually, etc.) to perform ultraviolet sterilization on the mouse.

The method according to some embodiments of the present disclosure can control the height of the ultraviolet light emitting device by using the lifting unit, so as to achieve sufficient sterilization of each part of the mouse.

In some embodiments, the ultraviolet light emitting device disposed on the mouse may sterilize the keyboard when the application program determines that the mouse has been placed in a prescribed position.

FIG. 9 is an exemplary flow chart illustrating a determination of whether a mouse has been placed in a prescribed position according to some embodiments of the present description.

As shown in flow 900, in some embodiments, the controller may determine whether the mouse is placed in a prescribed position by the electro-optical scanning unit.

In some embodiments, when the mouse is sterilized by the keyboard, or when the mouse is sterilized by the keyboard, the user can press a specific key to ensure that the hand is present at a specific position, and the target hand is identified by the photoelectric scanning unit, which indicates that the mouse is placed at the specified position. For example, when the mouse is in place, the user may hold his hand at a particular key (e.g., the "H" key on the keyboard) near a defined location (e.g., the middle of the keyboard) for a period of time (e.g., 1 second, 3 seconds, etc.). The photoelectric scanning unit recognizes the hand of the user, determines that the hand of the user has appeared at the specific position 'H' key, and thus determines that the mouse has been located at the prescribed position.

When the mouse and the keyboard are in the same plane or are vertically placed, the relative position of the mouse and the keyboard is difficult to determine through the photoelectric scanning unit.

FIG. 10 is an exemplary flow chart of a keyboard power control method according to some embodiments described herein. As shown in fig. 10, the process 1000 may include the following steps. In some embodiments, process 1000 may be performed by keyboard 110.

And step 1010, performing electricity utilization statistics. In some embodiments, step 1010 may be performed by determination module 1120.

In some embodiments, the electricity usage statistics include at least one of charge statistics and sterilization statistics.

In some embodiments, the power statistics may include obtaining keyboard power information by detecting keyboard power. The keyboard power information is used to indicate the remaining power of the keyboard and may be transmitted to a driver installed in a device connected to the keyboard through a network. The device connected with the keyboard can be a computer, a tablet computer, a mobile phone and the like.

In some embodiments, the sterilization statistics may include determining an execution of a sterilization plan based on the sterilization plan determination and an actual sterilization situation. The sterilization statistics may include at least one information related to the execution of the sterilization plan, such as whether the sterilization plan is executed, the actual sterilization duration, the expected sterilization duration, the time duration to complete sterilization, the planned sterilization intensity and the actual sterilization intensity of the ultraviolet light emitting device, and the like.

In some embodiments, the sterilization plan may be determined based on user input by obtaining user input. The user input may include user key information from which user key characteristics may be determined.

For more details regarding the determination of a sterilization plan based on user input, reference may be made to

steps

420, 430 and their associated description in FIG. 4.

In some embodiments, in response to the remaining available time of the battery not meeting the preset condition, the record of the power consumption statistics may be updated in combination with the remaining battery capacity of the keyboard, and the sterilization plan may be adjusted according to the updated record of the power consumption statistics. The preset condition may include whether the remaining battery usable time meets a threshold, the threshold may be determined according to an estimated keyboard use duration, and the estimated keyboard use duration may include at least one of a duration of actual keyboard use expected by a user and a duration of planned sterilization.

In some embodiments, updating the record of the electricity usage statistics may include updating the remaining available time of the battery and the determination result of whether the time satisfies the preset condition to the record of the electricity usage statistics.

In some embodiments, further adjustments to the current sterilization plan may be made based on the remaining available time of the battery in the record of updated power usage statistics. For example, when the remaining usable time of the battery is longer than the time when the user expects to actually use the keyboard, the light intensity or the sterilization time of the ultraviolet light emitting device may be appropriately reduced to ensure that the remaining capacity can perform sterilization while prompting the user that the sterilization plan has been changed. For another example, if the remaining usable time of the battery is shorter than the time when the user expects to actually use the keyboard, the sterilization plan may be temporarily cancelled and a prompt may be issued to the user to ensure that the user uses the keyboard normally.

At step 1020, the remaining usable time of the battery is determined. In some embodiments, step 1020 may be performed by determination module 1120.

In some embodiments, the remaining usable time of the battery may be determined according to the result of the power usage statistics. For example, the residual capacity and the completion condition of the sterilization plan can be obtained according to the results of the power statistics and the sterilization statistics, if the sterilization is completed, the estimated power consumption of the user only using the keyboard for input is estimated, and the remaining usable time of the battery is determined according to the estimated power consumption and the residual capacity; if sterilization has not been performed, estimated power consumption of the user using the keyboard for input and estimated power consumption of the keyboard for executing a sterilization plan are estimated, and remaining usable time of the battery is determined based on the sum of the estimated power consumption and the estimated power consumption of the keyboard for executing the sterilization plan.

In some embodiments, the user may be determined from the key data and the remaining usable time of the battery may be updated based on the user keyboard usage. For example, the actual use frequency of the user in the process of using the keyboard and the sterilization plan corresponding to the user are determined according to the user, the predicted actual use time of the user is determined according to the actual use frequency of the keyboard, the luminous intensity and the sterilization time of the ultraviolet light-emitting device are determined according to the sterilization plan corresponding to the user, the predicted power consumption is determined according to the actual use time of the keyboard, the luminous intensity and the sterilization time of the ultraviolet light-emitting device, and the remaining available time of the battery is calculated by combining the remaining electric quantity.

In some embodiments, the estimated power consumption may be determined according to actual usage of the keyboard by different users in combination with power consumption information in historical keyboard usage data. In some embodiments, at least one operating mode of the keyboard, and power consumption in each operating mode, may be obtained from historical keyboard usage data by the application. For example, power consumption in the sterilization mode or the non-sterilization mode, power consumption in different sterilization modes, and the like. The different working modes correspond to different actual use time of the keyboard, different luminous intensities of the ultraviolet light-emitting devices and different sterilization time. For each working mode, the power consumption in each working mode can be obtained through a data manual or self-test statistical power consumption according to the relevant data of the keyboards in different working modes, and then the power consumption is estimated when the user actually uses the keyboard.

In some embodiments, the keystroke data can include at least one of user input, user keystroke characteristics. Determining more of the user's content based on the keystroke data can be seen in step 510 of FIG. 5 and its associated description.

In order to ensure that the sterilized keyboard can be used when the user uses the keyboard, the sterilization plan is executed every time the user changes the keyboard. In some embodiments, the remaining usable time of the battery may also be adjusted according to the frequency of user replacement. For example, if the user replacement frequency is high, the number of times of executing the sterilization plan will also increase, and the power consumption for executing the sterilization plan will also increase, and the determination module 1120 may recalculate the estimated power consumption during the keyboard usage process according to the user replacement frequency, and adjust the remaining available time of the battery by combining the keyboard power consumption and the remaining power amount under the condition that the user replacement frequency is high.

In some embodiments of the present description, the remaining available time of the battery is adjusted by combining the replacement frequency of the user, and the difference of the execution frequency of the keyboard sterilization plan in different situations is fully considered, so that the remaining available time of the battery can be better determined, and the management and the control of the keyboard electric quantity can be more accurately performed.

And step 1030, sending a prompt to the user based on the result of the electricity utilization statistics. In some embodiments, step 1030 may be performed by hinting module 1130.

In some embodiments, in response to the remaining available time of the battery meeting a preset condition, the result of the electricity consumption statistics is retained, and the user is prompted for the situation of the sterilization statistics and the remaining available time of the battery based on the result. The prompting mode can include text prompting, voice prompting and the like.

In some embodiments of the present description, the remaining available time of the battery is determined, the sterilization plan is adjusted according to the remaining available time of the battery and the actual use requirement of the user, the remaining available time of the battery is updated according to the adjusted sterilization plan, and a prompt is sent to the user, so that the user can timely master the electric quantity information of the keyboard and the condition of the sterilization plan, the user can confirm or further adjust the sterilization plan according to the use requirement of the user, the electric quantity of the keyboard can be better controlled and managed, meanwhile, the sterilization effect and the execution flexibility of the sterilization plan are ensured, and the user can obtain better use experience.
