Description

[Technical Field]

[0001] The present invention relates to the field of electric tooth-cleaning devices, and more particularly to the field of controlling electric toothbrushes. [Background technology]

[0002] Many electric toothbrushes can be operated according to several different operating modes, which are automatically changed based on the replaceable brush head attached to the electric toothbrush.

[0003] When a user first begins using an electric toothbrush, an operating mode is typically applied to the electric toothbrush based on the toothbrush's factory settings and the replaceable brush head currently installed. If the user changes the current brush head to a different brush head that has a different recommended operating mode associated with it, the electric toothbrush automatically changes the current operating mode to the different recommended operating mode. Summary of the Invention [Problem to be solved by the invention]

[0004] However, users may not be aware that the new replaceable brush head has a recommended operating mode that differs from the current operating mode of the electric toothbrush. Therefore, automatically changing the operating mode of the electric toothbrush may result in an unexpected change that leads to confusion for the user and a decrease in the effectiveness of brushing using the electric toothbrush.

[0005] Therefore, there is a need for a way to control the operation of an electric toothbrush without overwhelm- ing the user.

[0006] U.S. Patent Application No. 2007 / 079455 discloses a toothbrush with an ultrasonic transducer for generating vibrations at sonic frequencies, the device head having an identifier associated with an operating protocol such that the associated operating protocol is executed, for example, at the start of an operating cycle.

[0007] US Patent Application No. 2020 / 029680 discloses an electric toothbrush that identifies toothbrush head attachments, where the user defines desired output characteristics for the toothbrush head. [Means for solving the problem]

[0031] The present invention will be described with reference to the drawings.

[0032] It should be understood that the detailed description and examples, while indicating exemplary embodiments of the devices, systems, and methods, are for illustration purposes only and are not intended to limit the scope of the invention. These and other features, aspects, and advantages of the devices, systems, and methods of the present invention will become better understood from the following description, appended claims, and accompanying drawings. It should be understood that the figures are schematic only and are not drawn to scale. It should also be understood that the same reference numerals are used throughout the figures to denote the same or similar parts.

[0033] The present invention provides a method for controlling the operation of an electric toothbrush having a replaceable brushhead, the method comprising the steps of obtaining an existing operational mode of the electric toothbrush, and, when a new replaceable brushhead is provided to the electric toothbrush, identifying the new replaceable brushhead, a new operational mode associated with the new replaceable brushhead is identified, the new operational mode being different from the existing operational mode.

[0034] A user input is requested to confirm that the operation of the electric toothbrush should change to the new mode of operation. If the user provides input confirming that the operation of the electric toothbrush should change to the new mode of operation, the operation of the electric toothbrush is changed to the new mode of operation. If the user provides input indicating that the operation of the electric toothbrush should not change to the new mode of operation, or if the user does not provide user input, the existing mode of operation of the electric toothbrush is maintained.

[0035] FIG. 1 illustrates a method 100 for controlling the operation of an electric toothbrush with a replaceable brush head.

[0036] The method begins in step 110 by obtaining an existing operating mode of the electric toothbrush. The existing operating mode may be any current operating mode of the electric toothbrush. For example, the existing operating mode may be associated with an existing replaceable brush head attached to the electric toothbrush. Alternatively, the existing operating mode may be the standard recommended two-minute brushing routine.

[0037] When a new replaceable brush head is provided to the electric toothbrush, the new replaceable brush head is identified in step 120. Identifying the new replaceable brush head includes obtaining a brush head identification code from the new replaceable brush head and identifying the new replaceable brush head based on the brush head identification code. Examples of brush head identification codes are described below with reference to Figures 2 and 4.

[0038] In step 130, a new operational mode associated with the new replaceable brush head is identified. The new operational mode includes one or more of a new brushing routine, a new brushing intensity, a new brushing time, a new brushing amplitude, and a new brushing frequency. The new operational mode may include any combination of changes to the operational mode of the electric toothbrush. For example, the new operational mode includes a new brushing frequency and a new brushing amplitude or pressure. Alternatively, the new operational mode includes a new brushing time and a new brushing frequency, such as more frequent but shorter brushing sessions. If the new operational mode is different from the existing operational mode, the method continues. If the new operational mode is the same as the existing operational mode, no change in operational mode occurs and no user input needs to be requested.

[0039] An input is requested from the user to confirm that the operation of the electric toothbrush should change to the new mode of operation at step 140. The input may be requested from the user in several ways, examples of which are described below with reference to Figures 2-4.

[0040] If the user provides input confirming that the operation of the electric toothbrush should change to the new mode of operation, the method proceeds to step 150 and the operation of the electric toothbrush is changed to the new mode of operation.

[0041] If the user provides input indicating that the operation of the electric toothbrush should not change to the new operating mode, or if the user does not provide input, the method proceeds to step 160 and the existing operating mode of the electric toothbrush is maintained.

[0042] For example, when a user first begins using an electric toothbrush, an operating mode is selected based on the electric toothbrush's factory settings and the replaceable brush head that is attached. If the user then changes the existing replaceable brush head to a new replaceable brush head with a different recommended brushing routine or a new operating mode, the electric toothbrush's existing operating mode does not automatically change to avoid confusing the user.

[0043] Rather, a request is provided to the user to provide input confirming that the user wishes to change the operation of the electric toothbrush. For example, if the electric toothbrush is connected to a smart device belonging to the user, the request is provided to the user, for example, via an application or other software on the smart device. The request includes a recommendation to change the operational mode based on the new replaceable brushhead. If the user does not select to change from the existing operational mode to the new operational mode, the electric toothbrush remains in the existing operational mode with the new replaceable brushhead. If the user selects to change from the existing operational mode to the new operational mode, the operational mode of the electric toothbrush changes accordingly.

[0044] If a user provides a new replaceable brush head that can only be used for one particular function, e.g., a tongue care brush head for performing a tongue care routine, providing the new replaceable brush head is interpreted as a confirmatory user input indicating a desire to change the operational mode of the electric toothbrush to the new operational mode. In other words, if the new replaceable brush head can only be used for one particular function, the user may not be given a separate request to confirm the change in operational mode.

[0045] After the user confirms that the operational mode of the electric toothbrush should change to the new operational mode, the user may wish to further adjust the new operational mode to better suit the user's individual needs. In this case, the method further includes receiving additional user input to adjust the new operational mode and updating the new operational mode based on the additional user input, thereby generating an updated operational mode. Operation of the electric toothbrush is then changed to the updated operational mode.

[0046] The additional user input may be provided in a manner similar to the user input confirming that the operational mode of the electric toothbrush should be changed, or using any other suitable user input. For example, the user provides the user input via a user interface provided on the electric toothbrush itself, on an accessory of the electric toothbrush, such as a charging unit, or on a smart device connected to the electric toothbrush.

[0047] 2 shows a schematic representation of an electric toothbrush 200 that forms at least part of a system for controlling the operation of an electric toothbrush with a replaceable brushhead. The electric toothbrush comprises a body portion 210 and a replaceable brushhead 220, the replaceable brushhead being adapted to be presented to a user's mouth to perform an oral care routine. The body portion 210 of the electric toothbrush 200 comprises a battery 230 and a drive unit 240 for operating the replaceable brushhead 220.

[0048] In the example shown in Figure 2, the electric toothbrush 200 comprises a processing unit 250 for controlling the operation of the electric toothbrush, the processing unit being adapted to perform any of the methods described above with reference to Figure 1.

[0049] More particularly, the processing unit 250 is adapted to obtain an existing operational mode of the electric toothbrush, identify a new replaceable brushhead when the new replaceable brushhead is provided to the electric toothbrush, identify a new operational mode associated with the new replaceable brushhead, where the new operational mode is different from the existing operational mode, request input from a user to confirm that operation of the electric toothbrush should change to the new operational mode, change operation of the electric toothbrush to the new operational mode if the user provides input confirming that operation of the electric toothbrush should change to the new operational mode, and maintain the existing operational mode of the electric toothbrush if the user provides input indicating that operation of the electric toothbrush should not change to the new operational mode or if the user does not provide user input.

[0050] The electric toothbrush 200 further comprises a brush head identification unit 260 adapted to obtain an identifier of the replaceable brush head 220, and identification of a new replaceable brush head and a new operating mode is based on the obtained identifier.

[0051] For example, replaceable brush head 220 may include a radio frequency identification (RFID) tag 270, in which case identification unit 260 may include an RFID reader. When a new replaceable brush head is applied to body portion 210 of the electric toothbrush, the RFID tag is brought within range of the RFID tag reader of the identification unit. The identifier of the replaceable brush head is then read from the RFID tag by the identification unit and provided to processing unit 250 for identifying the new replaceable brush head and a corresponding new operating mode. For example, the electric toothbrush may include a memory unit containing a look-up table of identifiers, replaceable brush heads corresponding to the identifiers, and operating modes corresponding to the replaceable brush heads.

[0052] Alternatively, the electric toothbrush comprises a communications unit in communication with a remote processing unit, the remote processing unit adapted to perform the same operations as the above-described processing unit 250. The identifier of the replaceable brush head obtained by the identification unit is communicated to the remote processing unit for identifying a new replaceable brush head and a corresponding new operating mode.

[0053] In the example shown in FIG. 2, electric toothbrush 200 further comprises a user interface 280 adapted to provide a request to a user to confirm that the operation of the electric toothbrush should be changed and to receive user input in response to the request.

[0054] For example, the user interface includes one or more of a light source for communicating a request via a light signal, a display for providing a visual request, a speaker for providing an audible request, etc. Additionally, the user interface includes one or more of a button, where the user input includes a button press, a button hold, a series of button presses, etc., a microphone, where the user input includes an audible user input, a touch screen, where the user input includes a tactile user input, etc.

[0055] Figure 3 shows a schematic representation of a system 300 for controlling the operation of an electric toothbrush 310 having a replaceable brush head 312. The electric toothbrush 310 comprises one or more of the components described above with reference to Figure 2. As described above, the electric toothbrush comprises an identification unit 315 for obtaining an identifier from the replaceable brush head.

[0056] In the example shown in Fig. 3, the system 300 comprises a charging unit 320 adapted to receive and charge the electric toothbrush 310. Furthermore, the charging unit 320 comprises a processing unit 330 implemented as described above with reference to Fig. 2. In other words, the processing unit is provided in the charging unit of the system, rather than in the electric toothbrush itself. An identification unit of the electric toothbrush is brought into communication with the processing unit when the electric toothbrush is brought into contact with the charging unit.

[0057] The electric toothbrush 310 and the charging unit 320 may further comprise a communication unit for establishing wireless communication between the electric toothbrush and the charging unit when they are not physically connected.

[0058] Additionally, the charging unit includes a user interface 340 implemented as described above with reference to FIG.

[0059] 4 shows a schematic representation of a system 400 for controlling the operation of an electric toothbrush 410 having a replaceable brush head 412, the electric toothbrush including a communication unit 415 in wireless communication with a remote processing unit in the form of a smart device 420. It should be noted that any remote processing unit capable of communicating with the communication unit may be used to perform the methods herein. For example, at least a portion of the remote processing unit may be incorporated into a computer, laptop, tablet, server, distributed processing network, etc.

[0060] In the example shown in FIG. 4, smart device 420 is a smartphone, but smart devices include one or more of a smartphone, a smart watch, and a smart home device.

[0061] One or more of the processing unit, the user interface, and the identification unit may be incorporated into a smart device.

[0062] In the example shown in Figure 4, the electric toothbrush includes an identification unit 430 for obtaining an identifier from the replaceable brush head, as described above with reference to Figure 2. However, the identification unit may also be incorporated into the smart device, for example, by using the smart device's camera to scan a visual code on the replaceable brush head, such as a QR code or barcode. The visual code may be provided on the brush head itself or on a packaging element for the replaceable brush head. Furthermore, in the example shown in Figure 4, the processing unit and user interface are incorporated into the smart device 420.

[0063] As an example, when a user provides the electric toothbrush 410 with a new replaceable brush head 412, the identification unit 430 obtains the replaceable brush head's identifier, for example, by reading an RFID tag on the replaceable brush head. The identifier is then provided to the communication unit 415 for communication to a connected smart device 420, such as the user's smartphone.

[0064] Upon receiving the identifier of the replaceable brush head, the smart device is adapted to, via a processing unit of the smart device, identify a new replaceable brush head based on the received identifier and identify a new operational mode corresponding to the identified replaceable brush head. For example, the smart device utilizes a look-up table stored in a local memory of the smart device or in a remotely accessible memory, such as a remote server accessed via the Internet, to identify the new replaceable brush head and the new operational mode based on the obtained identifier.

[0065] Upon identifying the new operational mode, the smart device provides input to the user to confirm that the operational mode of the electric toothbrush 410 should change from the existing operational mode to the new operational mode. The request may be provided, for example, via an application or other software provided on the smart device. User input may include any suitable input from the user, such as providing touch input on a touch-enabled surface of the smart device, pressing a button on the smart device, providing audible input to be received by a microphone on the smart device, etc.

[0066] If the user provides input confirming that the operation of the electric toothbrush should change to the new operating mode, the smart device communicates to the electric toothbrush via the communication unit 415 that the operation of the electric toothbrush should change to the new operating mode.

[0067] If the user provides input indicating that the operation of the electric toothbrush should not change to the new operating mode, the smart device communicates to the electric toothbrush via the communication unit 415 that the existing operating mode of the electric toothbrush should be maintained.

[0068] If the user does not provide any input, for example because the user did not see the request, the existing operating mode of the electric toothbrush is maintained until the user provides input.

[0069] It should be noted that any combination of the embodiments described in Figures 2-4 may also be achieved, for example, the identification unit is integrated into the electric toothbrush, the processing unit is integrated into the charging unit, and the user interface is integrated into the smart device, with each component being linked by one or more communication units.

[0070] The system described above may receive additional user input to adjust the new operating mode of the electric toothbrush. In the example shown in Figure 4, the user may provide additional input to the smart device to indicate the desired adjustment to the operating mode of the electric toothbrush.

[0071] The system then updates the new operating mode based on the additional user input in a manner similar to that described above, thereby generating an updated operating mode and changing the operation of the electric toothbrush to the updated operating mode.

[0072] Variations to the disclosed embodiments can be understood and effected by those skilled in the art in practicing the claimed invention, from a study of the drawings, the disclosure, and the appended claims. In the claims, the words "comprises" or "having" do not exclude other elements or steps, and the words "a" or "an" do not exclude a plurality.

[0073] A single processor or other unit may fulfill the functions of several items recited in the claims.

[0074] The mere fact that certain measures are recited in mutually different dependent claims does not indicate that a combination of these measures cannot be used to advantage.

[0075] The computer program may be stored / distributed on a suitable medium, such as an optical storage medium or a solid-state medium supplied together with or as part of other hardware, but may also be distributed in other forms, such as via the Internet or other wired or wireless telecommunications systems.

[0076] It should be noted that when the term "adapted to" is used in the claims or this specification, it is intended to be equivalent to the term "configured to."

[0077] Any reference signs in the claims should not be construed as limiting the scope.
