[0027] With the development of industry technology, large swing angle vibration of oral cleaning equipment has become a new trend in the industry. Large swing angle means a larger cleaning area and stronger cleaning ability, which can significantly improve cleaning efficiency.

[0028] However, blindly pursuing a larger swing angle may also bring adverse effects. A larger swing angle means that the back of the cleaning part will hit the teeth more seriously. High swing angle and high frequency of hitting the teeth may even cause hidden dangers such as tooth damage. In addition, a larger swing angle often means more noise, more operating current, and shorter battery life, which seriously affects the user's oral cleaning experience.

[0029] In order to solve the above technical problems, the solution provided by the present application is to divide the large swing angle of the first preset angle into zones, and within a rotation cycle of the cleaning unit, the number of rotations of the cleaning unit in each swing angle interval is greater than or equal to 2, so that the reciprocating swing amplitude of the cleaning unit becomes smaller, which solves the problem that the back of the cleaning unit hits the teeth more seriously due to the large swing angle, and may even cause hidden dangers such as tooth damage, and reduces noise, reduces working current, increases battery life, and improves the user's oral cleaning experience. The oral cleaning device provided by this solution has both the good experience of a small swing angle and the larger cleaning area and stronger cleaning ability of a large swing angle.

[0036] Embodiment 1

[0037] Figure 1 Schematic diagram of an oral cleaning device provided in Example 1 of the present application. This embodiment can be applied to oral cleaning scenarios. Figure 1 As shown, the oral cleaning device comprises:

[0038] A care head having a cleaning portion at a distal end thereof;

[0039] A gripping portion connected to the nursing head;

[0040] A power assembly, at least part of which is arranged in the grip portion, and includes:

[0041] a motor, the motor being configured to generate a periodic motion;

[0042] An output shaft, the output shaft is at least partially contained in the gripping portion and is configured to engage the care head; the output shaft is configured to transmit the generated periodic motion to the care head, so that the cleaning portion rotates periodically in a first direction, the periodic rotation includes a first cleaning motion within a first preset angle, the first preset angle includes N swing angle intervals, the first cleaning motion includes reciprocating rotational motion in the N swing angle intervals, within a rotation cycle of the cleaning portion, the cleaning portion rotates greater than or equal to M times in each swing angle interval, the first direction is around the central axis of the oral cleaning device, N ≥ 2, M ≥ 2.

[0043] It can be understood that the first preset angle is the large swing angle that needs to be partitioned. The first preset angle can be divided into N swing angle intervals. The size of each swing angle interval can be different.

[0044] It can be understood that the first direction is a circumferential direction. The first cleaning motion is a reciprocating rotation motion in the circumferential direction.

[0045] Wherein, the central axis of the oral cleaning device is parallel to or overlaps with the central axis of the output shaft.

[0046] The oral cleaning device may be an electric toothbrush or an all-in-one flushing machine. Taking the oral cleaning device as an electric toothbrush as an example, the electric motor is used to make large sweeping movements to improve the cleaning effect of the oral cavity. During the sweeping movement of the motor, the output shaft of the motor rotates periodically about its own central axis. The care head may be a brush head with bristles at its distal end. The vibration of the electric toothbrush is manifested as a small reciprocating motion of the bristle surface with the center of the initial position as the swing center, that is, a reciprocating rotation motion in the circumferential direction, and the swing center line is parallel to or overlaps with the central axis of the output shaft.

[0047] refer to Figure 2 , the first preset angle can be divided into 4 swing angle intervals, namely swing angle interval I, swing angle interval II, swing angle interval III and swing angle interval IV. Of course, the first preset angle can also be divided into only 2 swing angle intervals. Based on the actual needs of the user, the sizes of these four swing angle intervals can be different. Figure 2 The symmetric center line of the cleaning part shown in the figure coincides with the boundary 3. When the cleaning part performs reciprocating rotational motion around the central axis in the swing angle interval I, the movement angle of the cleaning part is between the boundary 1 and the boundary 2, that is, the symmetric center line of the cleaning part is between the boundary 1 and the boundary 2. Similarly, when the cleaning part performs reciprocating rotational motion around the central axis in the swing angle interval II, the movement angle of the cleaning part is between the boundary 2 and the boundary 3, that is, the symmetric center line of the cleaning part is between the boundary 2 and the boundary 3. Similarly, when the cleaning part performs reciprocating rotational motion around the central axis in the swing angle interval III, the movement angle of the cleaning part is between the boundary 3 and the boundary 4, that is, the symmetric center line of the cleaning part is between the boundary 3 and the boundary 4. Similarly, when the cleaning part performs reciprocating rotational motion around the central axis in the swing angle interval IV, the movement angle of the cleaning part is between the boundary 4 and the boundary 5, that is, the symmetric center line of the cleaning part is between the boundary 4 and the boundary 5. It can be understood that the position of the cleaning part at the beginning of the first cleaning movement is the center position of the first preset angle, and the cleaning part starts the first cleaning movement to the left or right from the initial position.

[0048] During implementation, the rotation cycle of a cleaning section can be set as: first, reciprocating rotation motion is performed in the swing angle interval III, then, reciprocating rotation motion is performed in the swing angle interval IV, then, reciprocating rotation motion is performed in the swing angle interval III, then, reciprocating rotation motion is performed in the swing angle interval II, then, reciprocating rotation motion is performed in the swing angle interval I, and finally, reciprocating rotation motion is performed in the swing angle interval II.

[0049] This solution divides the large swing angle of the first preset angle into zones, and within a rotation cycle of the cleaning unit, the number of rotations of the cleaning unit in each swing angle interval is greater than or equal to 2, so that the reciprocating swing amplitude of the cleaning unit becomes smaller, which solves the problem that the back of the cleaning unit will hit the teeth more seriously due to the large swing angle, and may even cause hidden dangers such as tooth damage, and reduces noise, reduces working current, increases battery life, and improves the user's oral cleaning experience. The oral cleaning device provided by this solution has both the good experience of a small swing angle and the larger cleaning area and stronger cleaning ability of a large swing angle.

[0050] In an implementable manner, the periodic rotation further includes a second cleaning motion within a second preset angle, the second preset angle is smaller than the first preset angle, and the cleaning part performs the second cleaning motion while performing the first cleaning motion.

[0051] The rotation in the periodic rotation may include sweeping and vibration.

[0052] The oral cleaning device in this scheme can perform sweeping and vibration integrated motion, that is, the cleaning part performs a sweeping motion while maintaining vibration. Among them, the first cleaning motion is a low-frequency large-angle sweeping motion, and the second cleaning motion is a high-frequency small-angle vibration. Generally speaking, the high-frequency amplitude of vibration is small, and there is no need to partition the vibration movement angle, so the large swing angle partition in this scheme is aimed at the sweeping motion. The motor makes a small-amplitude high-frequency swing, which drives the brush head bristles to produce high-frequency vibrations, and instantly breaks down the toothpaste into fine foams to deeply clean the teeth. In addition, the electric toothbrush vibrates while performing a large-amplitude sweep, thereby improving the cleaning effect of the oral cavity to a certain extent. Whether it is sweeping or vibrating, the motor shaft of the servo motor rotates with its own central axis. Vibration is manifested as a small reciprocating motion of the bristle surface with the center of the initial position as the swing center, and sweeping is manifested as the direction of the bristle surface changing while maintaining vibration.

[0053] refer to Figure 2 , the angle value between movable boundary 1 and movable boundary 2 represents the second preset angle, and also represents the vibration amplitude of each vibration of the cleaning unit, that is, the second preset angle represents the vibration amplitude of the cleaning unit. The vibration amplitude of the cleaning unit is proportional to the cleaning strength of the cleaning unit. The larger the second preset angle, the larger the vibration amplitude of the cleaning unit. The larger the vibration amplitude of the cleaning unit, the greater the cleaning strength.

[0054] It can be understood that when the cleaning part reciprocates in the swing angle interval I, the symmetry center line of the cleaning part can reciprocate M times between the boundary 1 and the boundary 2, M ≥ 2. While the cleaning part vibrates in the movable boundary 1 and the movable boundary 2, it reciprocates in the boundary 1 and the boundary 2.

[0055] In one implementable manner, the first preset angle is greater than or equal to 10 degrees and less than or equal to 100 degrees.

[0056] During implementation, the first preset angle is reasonably set to facilitate oral cleaning.

[0057] In one achievable manner, the second preset angle is less than 10 degrees.

[0058] During implementation, the second preset angle is reasonably set to facilitate oral cleaning.

[0059] In an implementable manner, the first cleaning motion includes driving the care head to sweep at a first preset frequency, and the first preset frequency is greater than or equal to 20 degrees per second and less than or equal to 2000 degrees per second.

[0060] During implementation, the first preset frequency for driving the nursing head to sweep is reasonably set to utilize oral cleaning.

[0061] In an implementable manner, the second cleaning motion includes driving the care head to vibrate at a second preset frequency, where the second preset frequency is greater than or equal to 100 Hz and less than or equal to 700 Hz.

[0062] During implementation, the second preset frequency for driving the nursing head to vibrate is reasonably set to facilitate oral cleaning.

[0063] In one possible implementation, N≥4.

[0064] During implementation, it was found that when the first preset angle is divided into 4 or more swing angle intervals, the problem of hitting the teeth can be effectively avoided. For example, if the first preset angle is 100 degrees, when it is divided into 2 swing angle intervals, a single swing angle interval is at least 50 degrees, which is still a relatively large swing angle; when it is divided into 4 swing angle intervals, a single swing angle interval can be 25 degrees, which can effectively avoid the back of the cleaning part hitting the teeth.

[0065] In one possible implementation, two adjacent swing angle intervals partially overlap.

[0066] It can be understood that two adjacent swing angle intervals may not overlap, or may partially overlap, but cannot completely overlap.

[0067] This solution can achieve better cleaning effect and gentler oral cleaning experience by partially overlapping two adjacent swing angle intervals.

[0068] In an implementable manner, the first preset angle has a boundary, and when performing the first cleaning motion, the cleaning intensity of the cleaning portion in a swing angle interval adjacent to the boundary is smaller than the cleaning intensity in a swing angle interval away from the boundary.

[0069] refer to Figure 2, Boundary 1 and Boundary 5 can be used as two boundaries of the first preset angle. Swing angle interval I and swing angle interval IV can be used as swing angle intervals near the boundary. Swing angle interval II and swing angle interval III can be used as swing angle intervals far from the boundary.

[0070] It is understandable that when the oral cleaning device moves in the swing angle interval near the first preset angle boundary, it is easier for the cleaning part to hit the gums. This solution can better protect the gums by controlling the cleaning intensity of the cleaning part in the swing angle interval near the boundary to be lower than the cleaning intensity of the swing angle interval far from the boundary when performing the first cleaning movement.

[0071] In one achievable manner, the cleaning intensity is determined based on the cleaning time and / or cleaning force, wherein the cleaning time is determined according to the rotation speed of the care head when performing the first cleaning motion, and the cleaning force is determined according to the vibration amplitude of the care head when performing the second cleaning motion.

[0072] It can be understood that, when the swing angle interval is constant and the number of reciprocating rotations is constant, the cleaning time is inversely proportional to the rotation speed of the care head when performing the first cleaning movement.

[0073] It can be understood that the cleaning force is proportional to the vibration amplitude of the care head performing the second cleaning motion.

[0074] It can be understood that the cleaning intensity is proportional to the cleaning time and the cleaning strength. Specifically, the longer the time the cleaning part performs reciprocating rotation in a certain swing angle range and the greater the vibration amplitude, the greater the cleaning intensity of the cleaning part in the swing angle range.

[0075] This solution can more conveniently control the cleaning intensity through the two dimensions of cleaning time and cleaning strength.

[0076] In one achievable manner, when the first cleaning motion is performed, the first preset angle is gradually expanded.

[0077] refer to Figure 2 One way to partition the first preset angle is to first divide it into smaller swing angle intervals such as boundary 2-boundary 4, and then gradually expand from the middle to the outside to increase the following swing angle intervals: boundary 1-boundary 2, boundary 4-boundary 5, and then complete the partitioning of the first preset angle. At the beginning of the first cleaning movement, the sweeping movement is performed at a smaller initial first preset angle, and then the swing angle interval is gradually expanded from the middle to both sides, that is, the first preset angle is expanded, so that the sweeping amplitude gradually increases. The initial smaller sweeping amplitude is convenient for users to adapt to the cleaning movement, and then the gradually increasing sweeping amplitude facilitates cleaning more sanitary dead corners in the oral cavity.

[0078] In one achievable manner, when performing the second cleaning motion, the second preset angles of the cleaning portion in different swing angle intervals are different.

[0079] It can be understood that since the cleaning force is proportional to the vibration amplitude of the second cleaning motion performed by the care head, the second preset angle can represent the vibration amplitude. Therefore, by controlling the second preset angle of the cleaning part in different swing angle intervals, the cleaning force in different swing angle intervals can be conveniently set as needed.

[0080] In an achievable manner, the oral cleaning device further comprises a control component, the control component is at least partially arranged in the grip portion, the control component is electrically connected to the power component and is used to control the power component to perform movement;

[0081] The oral cleaning device also includes an input component or a device control terminal for interacting with a user, and the device control terminal is connected to the oral cleaning device via a wireless signal or the input component is electrically connected to the control component;

[0082] The control component receives a motion parameter setting signal for the first cleaning motion and / or the second cleaning motion sent by the device control terminal or the input component, and sets the motion parameters of the first cleaning motion and / or the second cleaning motion.

[0083] In implementation, multiple gears can be provided for users to select operations using the input component, and each gear has corresponding motion parameters of the first cleaning motion and / or the second cleaning motion. The control component can control the power component to perform motion according to the gear. In this way, large swing angle partitions can be conveniently performed, and the cleaning intensity of each swing angle interval can be set separately as needed, thereby improving the user's oral cleaning experience.

[0084] Among them, the device control end can be a mobile terminal, such as a mobile phone. The user can use the mobile phone application to set the motion parameters of the first cleaning motion and / or the second cleaning motion. The control component can control the power component to perform the motion according to the set motion parameters of the first cleaning motion and / or the second cleaning motion. In this way, large swing angle partitions can be conveniently performed, and the cleaning intensity of each swing angle interval can be set separately as needed, thereby improving the user's oral cleaning experience.

[0085] In one achievable manner, the motion parameter includes at least one of a first preset angle, a second preset angle, a motion duration, a motion direction, a vibration frequency, and a sweeping frequency.

[0086] The first preset angle represents the sweeping amplitude of the cleaning part, that is, the maximum swing angle that can be used for partitioning. The user can customize the partitioning method of the first preset angle as needed.

[0087] The second preset angle represents the vibration amplitude of the cleaning part. The user can set the second preset angle of each swing angle interval individually as needed.

[0088] The motion duration may include at least one of the following: the duration of periodic rotation of the cleaning unit in the first direction, the duration of a rotation cycle of the cleaning unit, and the duration of the reciprocating motion of the cleaning unit in each swing angle interval.

[0089] The duration of the periodic rotation of the cleaning unit in the first direction may be an integer multiple of the duration of a rotation cycle of the cleaning unit.

[0090] Among them, the movement direction may include one of a first direction, a second direction, and a third direction. The first direction refers to the direction around the central axis of the oral cleaning device; the second direction is a direction parallel to or overlapping with the central axis; and the third direction is a direction perpendicular to the central axis.

[0091] The vibration frequency is the second preset frequency. The user can set the vibration frequency of the cleaning part in each swing angle interval as needed.

[0092] The sweeping frequency is a first preset frequency. The user can set the sweeping frequency of the cleaning part in each swing angle interval as required.

[0093] By setting the above motion parameters, it is possible to conveniently partition the large swing angle of the first preset angle, and to individually set the cleaning intensity of each swing angle interval as needed.

[0094] In an implementable manner, the output shaft is further configured to transmit the generated periodic motion to the care head, so that the cleaning section moves periodically in a second direction, and the second direction is parallel to the central axis of the oral cleaning device.

[0095] In practice, a bidirectional servo motor can be used to realize not only axial reciprocating rotation such as sweeping and vibration, but also axial reciprocating movement, so as to improve the user's oral cleaning experience.

[0096] In an implementable manner, the output shaft is further configured to transmit the generated periodic motion to the care head, so that the cleaning section moves periodically in a third direction, which is perpendicular to the central axis of the oral cleaning device.

[0097] In practice, a multi-directional servo motor can be used to realize axial reciprocating rotation, axial reciprocating movement, and compound knocking motion, in addition to sweeping motion and vibration, so as to improve the user's oral cleaning experience.

[0099] like Figure 3 As shown, the method includes:

[0100] Step 301: Acquire a trigger instruction, where the trigger instruction is used to instruct an output shaft of the oral cleaning device to perform movement.
