[0065] To make the features and advantages of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.
[0066] The terms "first," "second," "third," and the like in the specification and claims of this application and the accompanying drawings are used to distinguish between different objects, not to describe a particular order. Furthermore, the terms "including," "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements, but may optionally include steps or elements not listed, or may optionally include other steps or elements inherent to the process, method, product, or apparatus.
[0067] Next, an oral care device provided by an exemplary embodiment of the present application is introduced. The oral care device can be a device capable of performing oral care, such as, but not limited to, an electric toothbrush, a dental scaler, etc. The following embodiments are all described using an electric toothbrush as an example. Please refer to Figure 1 for details, which is a schematic diagram of the structure of an oral care device provided by an exemplary embodiment of the present application. As shown in Figure 1, the oral care device includes: a care piece 110 and a control unit 120. Among them:
[0068] The care piece 110 can swing or move with a certain amplitude based on the control of the control unit 120 or the manual operation of the user, thereby breaking down the toothpaste on the care piece 110 into fine foam to achieve deep cleaning of the teeth, etc.
[0069] The above-mentioned control unit 120 is located in the accommodating cavity of the handle housing and can be a microcontroller unit (MCU), also known as a single-chip microcomputer or single-chip microcomputer. It appropriately reduces the frequency and specifications of the central processing unit (CPU) and integrates peripheral interfaces such as memory, counter, USB, A / D conversion, UART, PLC, DMA, and even LCD driver circuits on a single chip to form a chip-level computer, which can perform different combination controls for different application scenarios.
[0070] Specifically, after receiving the user's oral care instructions, the control unit 120 can respond to the oral care instructions and determine the corresponding first drive signal and second drive signal; control the care component 110 to generate a first movement based on the first drive signal, and control the care component 110 to generate a second movement different from the motion trajectory of the first movement based on the second drive signal. The first movement and the second movement are generated alternately, so that by controlling the care component 110 to alternate between the first movement and the second movement with different motion trajectories, it is possible to apply peeling force to the soft plaque or dental plaque on the tooth surface in multiple directions, thereby producing a better oral care effect.
[0071] Optionally, the oral care device may also be equipped with, but not limited to, one or more indicator lights, buttons, display screens, speakers, motors, etc.
[0072] In some possible embodiments, as shown in FIG2 , the oral care device may further include a bidirectional motor, and the control unit of the oral care device may control the movement of the care component via the bidirectional motor. The bidirectional motor includes a first drive mechanism and a second drive mechanism, both of which are connected to the care component; the first drive mechanism is configured to drive the care component to generate a first movement based on a first drive signal; and the second drive mechanism is configured to drive the care component to generate a second movement based on a second drive signal.
[0073] Optionally, the control unit can control the output of a first drive signal to the first drive mechanism of the bidirectional motor, and control the output of a second drive signal to the second drive mechanism of the bidirectional motor, and the above-mentioned first drive signal and the above-mentioned second drive signal are output alternately, corresponding to the above-mentioned first drive mechanism and the second drive mechanism working alternately, and are configured to drive the nursing part to move alternately with the first motion and the second motion.
[0074] Optionally, the control unit can control the first drive mechanism that outputs the first drive signal to the bidirectional motor, and control the second drive mechanism that outputs the second drive signal to the bidirectional motor, and the above-mentioned first drive signal and the above-mentioned second drive signal are output at the same time, corresponding to the above-mentioned first drive mechanism and the second drive mechanism working at the same time, and is configured to drive the care part to produce a combined motion, and the motion trajectory of the combined motion is a curve, so that the care part is driven to produce a curved motion (such as a circular arc motion) so that it can smoothly scrape the tooth surface or the position where the tooth surface meets the gums during the oral care process, which has a better protective effect on the user's gums and is not easily injured by straight scraping.
[0075] Optionally, the above-mentioned first driving mechanism is configured to drive the nursing part to produce reciprocating swing with the length extension direction of the nursing part as the axis based on the first driving signal as shown in Figure 3; the above-mentioned second driving mechanism is configured to drive the nursing part to produce reciprocating movement along the length extension direction of the nursing part as shown in Figure 3 based on the second driving signal.
[0076] Next, with reference to FIG1 , a control method for an oral care device provided by an exemplary embodiment of the present application will be described, using the control method for an oral care device applied to an electric toothbrush as an example. Specifically, please refer to FIG4 , which exemplarily illustrates a flow chart of a control method for an oral care device provided by an embodiment of the present application. As shown in FIG4 , the control method for an oral care device includes the following steps:
[0077] S401, obtaining oral care instructions.
[0078] Specifically, when a user wants to use an oral care device for oral care, the user can, but is not limited to, trigger the oral care device to generate corresponding oral care instructions through buttons or display screens on the oral care device, or send corresponding oral care instructions to the oral care device through a terminal connected to the oral care device.
[0079] S402, in response to the oral care instruction, determining the corresponding first drive signal and second drive signal, controlling the care component to generate a first motion based on the first drive signal, and controlling the care component to generate a second motion based on the second drive signal, wherein the motion trajectories of the first motion and the second motion are different.
[0080] Optionally, the oral care instruction carries oral care parameters to be used by the oral care device after initiating oral care, such as, but not limited to, an oral care mode and an oral care intensity. The oral care device may pre-store a correspondence between each oral care parameter and the first drive signal and the second drive signal. Upon receiving the oral care instruction, the oral care device may respond to the instruction by finding the corresponding first drive signal and second drive signal from the correspondence based on the oral care parameters carried in the instruction.
[0081] It is understandable that in different oral care modes, at least one of the first drive signal and the second drive signal is different. The difference can be in the frequency, amplitude, or duty cycle of the signal itself, thereby forming different motion frequencies or motion amplitudes. The difference can also be in the alternating output duration of the two drive signals, thereby affecting the scraping time in different directions. Of course, the difference can also be in the number of drive mechanisms that can be driven by the two signals, thereby affecting single motion, combined motion, and thus the motion trajectory. Oral care devices with multiple drive mechanisms can combine more care modes to better meet user needs.
[0082] S403, alternately outputting the first driving signal and the second driving signal to control the nursing component to alternately output the first motion and the second motion.
[0083] In an embodiment of the present application, an oral care instruction is obtained; in response to the oral care instruction, a corresponding first drive signal and a second drive signal are determined; based on the first drive signal, the care piece is controlled to generate a first motion, and based on the second drive signal, the care piece is controlled to generate a second motion. The motion trajectories of the first motion and the second motion are different, and the first drive signal and the second drive signal are output alternately to control the care piece to alternately output the first motion and the second motion. By controlling the care piece to alternately move between the first motion and the second motion with different motion trajectories, a peeling force can be applied to the soft plaque or dental plaque on the tooth surface in multiple directions, thereby producing a better oral care effect and improving the oral care efficiency of the oral care equipment.
[0084] Optionally, the first motion and the second motion have different motion directions, so that by controlling the care piece to alternate between the first motion and the second motion having different motion trajectories and motion directions, the care piece can scrape the tooth surface in multiple directions, thereby further producing a better oral care effect.
[0085] Furthermore, as shown in FIG3 , the first motion may include reciprocating swinging (arc swinging) with the length extension direction of the care piece as the axis, and the second motion may include reciprocating movement (water linear vibration) along the length extension direction of the care piece, thereby controlling the care piece to alternate between reciprocating swinging (arc swinging) with the length extension direction of the care piece as the axis and reciprocating movement (linear vibration) along the length extension direction of the care piece, so that the linear vibration replaces the horizontal movement when the user manually uses the oral care device for oral care, and combined with the high-frequency swing of the care piece, simulates the up and down vibration of the oral care device when performing oral care, and the projections of the two trajectories on the tooth surface can be considered to be perpendicular to each other, so that the plaque can be better loosened, and the user can be helped to perform better oral care by controlling the mechanical movement of the care piece, avoiding the problem of the oral care effect being affected by individual user operation differences. At the same time, the above-mentioned movement mode is consistent with the movement mode of the care piece corresponding to the Bass brushing method. By controlling the care piece to move in the above-mentioned manner, the user can also directly master the Bass brushing method.
[0086] Furthermore, since the swing amplitude of the care piece is too large and may cause certain damage to the gums, the large extension and contraction amplitude (movement amplitude) of the care piece will not cause damage to the user's gums. Therefore, the movement amplitude of the above-mentioned second movement should be greater than the swing amplitude of the above-mentioned first movement, so that while protecting the gums, it can also improve the user's oral care efficiency by allowing the care piece to move back and forth with a larger movement amplitude along the length extension direction; and / or, the movement frequency of the above-mentioned second movement is less than the swing frequency of the first movement, so that the plaque in the gingival sulcus at the same oral position can be more efficiently removed by allowing the care piece to swing back and forth with a larger swing frequency with the length extension direction as the axis, thereby further improving the oral care efficiency of the oral care device.
[0087] Optionally, the movement directions of the above-mentioned first movement and the second movement may also be the same, but the amplitudes and / or duty cycles of the first drive signal for controlling the care part to generate the first movement and the second drive signal for controlling the care part to generate the second movement are different, resulting in different movement ranges of the first movement and the second movement generated by the care part. Therefore, by controlling the care part to alternately move between the first movement and the second movement with the same movement direction but different movement ranges, an arc movement is combined when the first movement and the second movement with different movement ranges are alternately switched, thereby further improving the oral care effect of the oral care device.
[0088] Optionally, the first motion and the second motion can both be reciprocating swings with the length extension direction of the care piece as the axis. The amplitude of the first drive signal for controlling the care piece to generate the first motion is smaller than the amplitude of the second drive signal for controlling the care piece to generate the second motion, and / or the duty cycle of the first drive signal for controlling the care piece to generate the first motion is smaller than the duty cycle of the second drive signal for controlling the care piece to generate the second motion, that is, the swing amplitude of the first motion is smaller than the swing amplitude of the second motion, and the duration of the first motion is greater than the duration of the second motion. In this way, the plaque can be stripped off the tooth surface by controlling the care piece to swing with a smaller swing amplitude for a longer time in the first motion, and then the plaque stripped off the tooth surface can be directly swept away from the tooth surface by controlling the care piece to swing with a larger swing amplitude in the second motion. In addition, this method is suitable for the side surfaces of the teeth. The second movement with a large swing amplitude can also form a certain massage effect on the gums when it swings to the edge. Since the second movement does not brush the gums continuously, but brushes the gums intermittently, it can avoid causing damage to the gums. At the same time, by controlling the care parts to alternately move with the corresponding duration of the first movement and the second movement, the gums can be scraped intermittently, thereby promoting blood circulation in the gums and achieving the effect of gum care.
[0089] Optionally, the oral care device may further include a bidirectional motor. As shown in FIG5 , the above-mentioned S402 controlling the care piece to generate a first motion based on the first drive signal and controlling the care piece to generate a second motion based on the second drive signal may include: controlling the bidirectional motor to drive the care piece to generate a first motion based on the first drive signal, that is, outputting a first drive signal to the bidirectional motor to drive the bidirectional motor to control the care piece to generate a first motion, and controlling the bidirectional motor to drive the care piece to generate a second motion based on the second drive signal, that is, outputting a second drive signal to the bidirectional motor to drive the bidirectional motor to control the care piece to generate a second motion, thereby controlling the care piece of the oral care device to alternately output vibrations of at least two different trajectories through the bidirectional motor based on the first drive signal and the second drive signal, so as to ensure that the oral care device can achieve multi-directional application of peeling force to the soft plaque or dental plaque on the tooth surface.
[0090] Optionally, as described in Figure 6, the above S403, alternately outputting the first drive signal and the second drive signal to control the nursing part to alternately output the first motion and the second motion may include: first outputting the first drive signal for a first duration to control the nursing part to continue the first motion for the first duration; then, pausing the output of the first drive signal, outputting the second drive signal for a second duration to control the nursing part to continue the second motion for the second duration; then, pausing the output of the second drive signal, and outputting the first drive signal again for the first duration, and so on, to achieve the control of the nursing part to alternate between the first motion and the second motion, and the above-mentioned first duration is greater than or equal to the second duration. In this way, the nursing part can be controlled to oscillate at high frequency (first motion) for a period of time, and then scrape laterally (second motion). The dirt peeled off from the tooth surface by the nursing part by the long-lasting high-frequency oscillation (first motion) is accumulated in one direction and then scraped away by lateral scraping (second motion), thereby further improving the oral care efficiency and oral care effect of the oral care device.
[0091] Furthermore, when the first motion and the second motion alternate, both the bidirectional motor and the care part require a certain amount of response time. If the first drive signal and the second drive signal are output alternately too quickly, the bidirectional motor will not be able to respond in time, resulting in the care part not being able to start oscillation. The next drive signal will drive it to drive the care part to produce the next motion, resulting in the care part being unable to achieve a good effect of alternating motion, thereby affecting the oral care effect. Therefore, the above-mentioned first duration and second duration should both be greater than the preset duration (for example, but not limited to 10ms, 1s, etc.), so as to avoid the problem of controlling the care part to alternate between the first motion and the second motion at too high a frequency, resulting in poor actual alternating motion of the care part, and further improve the oral care efficiency and oral care effect of the oral care device.
[0092] Optionally, the frequencies of the first drive signal and the second drive signal are different; and / or the duty cycles of the first drive signal and the second drive signal are different, that is, the frequencies of the first motion and the second motion are different and / or the duty cycles are different. In this way, during the oral care process, in addition to controlling the care parts to alternately move along different motion trajectories, different combined forces are formed in the motion force or motion switching speed of the care parts by controlling the frequency and / or duty cycle of the drive signal, further improving the oral care effect of the oral care device. Moreover, under the control of drive signals of different frequencies and / or duty cycles, the care parts of the oral care device can combine more complex motion trajectories, increase the diversity of care scraping methods, and further improve the oral care effect of the oral care device.
[0093] Optionally, the first movement may include a combination of multiple movements in different directions, and the second movement may be a single movement; the movement trajectory of the combined movement may be a curve, which produces a better protective effect on the user's gum line by applying force in an inclined manner, and the movement trajectory of the single movement may be a straight line, thereby controlling the care piece to alternately perform a combination of multiple movements in different directions and a single movement to remove dirt accumulated on the gum line, thereby improving the oral care effect.
[0094] Furthermore, the single motion includes a single swing or a single movement with the length extension direction of the care piece as the axis. As shown in Figure 7, the first drive signal includes a first sub-drive signal and a second sub-drive signal; the first sub-drive signal corresponds to a movement in a first motion direction, and the second sub-drive signal corresponds to a movement in a second motion direction, and the first motion direction and the second motion direction are different; the control of the care piece to generate the first motion based on the first drive signal may include: based on the first sub-drive signal and the second sub-drive signal, simultaneously controlling the care piece to generate the above-mentioned combined motion; the above-mentioned combined motion includes movement in the first motion direction and movement in the second motion direction, and the first motion direction or the second motion direction is the same as the motion direction corresponding to the second motion, and so on. By alternately outputting the first drive signal and the second drive signal, the care piece can be controlled to alternate between the combined motion and the single swing or between the combined motion and the single movement, which can effectively remove dirt accumulated on the gum line while providing a better protection effect on the user's gum line, thereby improving the oral care effect.
[0095] Next, please refer to Figure 8, which is a schematic diagram of the structure of a control device of an oral care device provided in an embodiment of the present application. The above-mentioned oral care device includes care parts. As shown in Figure 8, the control device 800 of the oral care device includes:
[0096] An acquisition module 810 is configured to acquire oral care instructions;
[0097] a control module 820 configured to determine a corresponding first drive signal and a second drive signal in response to the oral care instruction, control the care component to generate a first motion based on the first drive signal, and control the care component to generate a second motion based on the second drive signal, wherein the first motion and the second motion have different motion trajectories;
[0098] The output module 830 is configured to alternately output the first driving signal and the second driving signal to control the nursing component to alternately output the first motion and the second motion.
[0099] In a possible implementation manner, the first movement and the second movement have different movement directions.
[0100] In a possible implementation, the first motion includes reciprocating swinging with the length extension direction of the nursing component as the axis; the second motion includes reciprocating movement along the length extension direction of the nursing component.
