[0047] In the description of the present invention, "plurality" means two or more.

[0048] The following describes an oral cleaning device 1 according to an embodiment of the present invention with reference to the drawings.

[0049] like Figure 1-Figure 7 As shown in the figure (the direction indicated by arrow A is the length direction of the button assembly 400, the direction indicated by arrow B is the width direction of the button assembly 400, and the direction indicated by arrow C is the height direction of the button assembly 400), the oral cleaning device 1 includes a shell 100, a driving part, a circuit board 300, a button assembly 400 and an inductor 310.

[0050] The outer surface of the housing 100 is provided with a sliding installation groove 110, at least part of the driving member is located in the housing 100, the circuit board 300 is electrically connected to the driving member to output an adjustment signal to the driving member, and the inductor 310 is electrically connected to the circuit board 300. The key assembly 400 can be slidably installed in the sliding installation groove 110, at least part of the key assembly 400 is a conductor to form electromagnetic induction with the inductor 310, the key assembly 400 changes the inductance value of the inductor 310 when it is in different positions, and when the key assembly 400 slides, the inductance value changes continuously, so that the circuit board 300 can output a continuously changing adjustment signal according to the inductance value, and the driving member changes the working parameters with the change of the adjustment signal.

[0051] Among them, the oral cleaning device 1 can be an oral irrigator or an electric toothbrush. When the oral cleaning device 1 is an oral irrigator, the driving member can be a pump, and the working parameters of the driving member can be the flow rate and power of the pump. Therefore, when the working parameters of the driving member change, at least one of the jet water flow intensity and the jet water flow rate of the oral irrigator can be changed; when the oral cleaning device 1 is an electric toothbrush, the driving member can be a motor, and the working parameters of the driving member can be the vibration amplitude and vibration frequency of the motor. Therefore, when the working parameters of the driving member change, at least one of the vibration frequency and vibration amplitude of the electric toothbrush can be changed.

[0052] According to the oral cleaning device 1 of the embodiment of the present invention, a sliding mounting groove 110 is provided on the outer surface of the shell 100, and the button assembly 400 can be slidably installed in the sliding mounting groove 110, so that the user can easily access the button assembly 400 to change the working state of the oral cleaning device 1.

[0053] In addition, at least part of the driving component is located in the shell 100, the circuit board 300 is electrically connected to the driving component to output an adjustment signal to the driving component, the inductor 310 is electrically connected to the circuit board 300, at least part of the key assembly 400 is a conductor to form electromagnetic induction with the inductor 310, the key assembly 400 changes the inductance value of the inductor 310 when it is in different positions, the circuit board 300 can output a continuously changing adjustment signal according to the inductance value, and the driving component changes its working parameters as the adjustment signal changes.

[0054] Specifically, after the circuit board 300 is energized with alternating current, the inductor 310 will form an alternating magnetic field around it due to the alternating current. Since part of the key assembly 400 is a conductor, this part of the key assembly 400 will be affected by the magnetic field of the inductor 310 and generate eddy currents. The eddy currents will also affect the magnetic induction intensity and magnetic flux of the magnetic field of the inductor 310. When this part of the key assembly 400 is stationary, the inductance value of the inductor 310 remains fixed. When the distance between this part of the key assembly 400 and the inductor 310 changes, this part of the key assembly 400 changes. The magnetic induction intensity and magnetic flux of the eddy current change, thereby affecting the magnetic flux and magnetic induction intensity of the inductor 310, and the inductance value of the inductor 310 will change. The processor 320 of the circuit board 300 can continuously collect the current inductance value of the inductor 310 to obtain the change trend of the inductance value of the inductor 310, thereby obtaining the sliding direction and current position of the key assembly 400. The circuit board 300 can output a signal for adjusting the working parameters of the driver according to the sliding direction and current position of the key assembly 400 to achieve the adjustment of the working parameters of the driver.

[0055] Moreover, the distance between the conductor on the key assembly 400 and the inductor 310 is positively correlated with the inductance value, that is, when the conductor gradually approaches the inductor 310, the distance between the conductor and the inductor 310 gradually decreases, and the inductance value of the inductor 310 gradually decreases; when the conductor gradually moves away from the inductor 310, the distance between the conductor and the inductor 310 gradually increases, and the inductance value of the inductor 310 gradually increases.

[0056] In summary, the sliding button assembly 400 will cause the inductance value of the inductor 310 to change, and the circuit board 300 can send a signal for adjusting the working parameters of the driving component according to the inductance value.

[0057] Moreover, when the button assembly 400 slides, the inductance value changes continuously, so the circuit board 300 also continuously adjusts the working parameters of the driving part, that is, the circuit board 300 realizes stepless adjustment of the driving part. At this time, the oral cleaning device 1 has more working gears. At this time, each time the button assembly 400 slides a certain distance, there is a corresponding gear corresponding to it. The adjustment of the working parameters of the driving part is more precise, which can meet the needs of different users for the driving strength of the driving part and has higher applicability.

[0058] In this way, the oral cleaning device 1 according to the embodiment of the present invention can achieve stepless speed regulation, and has the advantages of precise speed regulation, easy adjustment and high applicability.

[0059] In some specific embodiments of the present invention, Figure 8 As shown, there are multiple inductors 310, and the multiple inductors 310 are arranged at intervals along the first direction. The multiple inductors 310 are electrically connected to the circuit board 300 respectively. The button assembly 400 moves along the first direction. The circuit board 300 can output a continuously changing adjustment signal according to the inductance values ​​of the multiple inductors 310, and the driving component changes the working parameters as the adjustment signal changes.

[0060] For example, each inductor 310 may be connected in parallel with a capacitor 330, and each inductor 310 and the capacitor 330 connected in parallel therewith form a parallel resonant circuit, and the resonant frequency of the parallel resonant circuit is Wherein L is the inductance value of the inductor 310 in the circuit, and C is the capacitance value of the capacitor 320 in the circuit. By connecting the inductor 310 and the capacitor 330 in parallel and making the above circuit an impedance circuit, the processor 320 of the circuit board 300 can more easily capture the voltage signal of the circuit, and the processor 320 can convert the above voltage signal into the current position signal of the key assembly 400, thereby controlling the driving component to operate with corresponding parameters.

[0061] The initial inductance values ​​of the multiple inductors 310 may be the same, for example, the initial inductance value may be 300 nH, and when the distance change of the key assembly 400 relative to each inductor 310 is the same, the absolute value of the change in the inductance value of each inductor 310 is the same. In other words, when the distance between the key assembly 400 and any one of the multiple inductors 310 changes from X to Y, the absolute value of the change in the inductance value of the inductor 310 is Z.

[0062] It should be noted that the initial inductance value refers to the inductance value of the inductor 310 after power is turned on without the influence of the key assembly 400 .

[0063] Since when the inductor 310 is far away from the button assembly 400, the sliding of the button assembly 400 has a relatively weak effect on the change of the inductance value of the inductor 310. Therefore, when the inductor 310 is far away from the button assembly 400, the short-distance sliding of the button assembly 400 may have no effect or a very weak effect on the change of the working parameters of the driver. In addition, the range of the inductance value of a single inductor 310 is limited and may not be able to fully cover the working parameter range of the driver. Therefore, when there is only one inductor 310, in order to ensure the adjustment stroke of the button assembly 400 and to ensure that the sliding of the button assembly 400 can effectively change the inductance value of the inductor 310, the size of the inductor 310 needs to be set relatively large, which will result in a larger volume of the oral cleaning device 1.

[0064] By setting a plurality of inductors 310, the size of each inductor 310 does not need to be large, and the overall sensing range of the inductor 310 can be increased, that is, by arranging the plurality of inductors 310 at intervals, the inductance value of at least one or several of the plurality of inductors 310 can be effectively changed according to the sliding of the key assembly 400, thereby ensuring that the current position and sliding direction of the key assembly 400 can be effectively detected, and the sliding stroke of the key assembly 400 can also be greatly improved. In this way, the position change of the key assembly 400 can have a significant impact on the adjustment of the working parameters of the driving member, improve the accuracy of the adjustment of the driving member, and the overall inductance value range of the inductor 310 is larger, so as to achieve full coverage of the working parameter range of the driving member, and the gear position of the oral cleaning device 1 is more diverse.

[0065] When the key assembly 400 slides, the inductance values ​​of at least two inductors 310 must change. By obtaining that one inductor 310 is gradually increasing or decreasing, it can be obtained whether the key assembly 400 is close to or away from the inductor 310. By obtaining that the inductance value of another inductor 310 is gradually increasing or decreasing, it can be obtained whether the key assembly 400 is close to or away from the inductor 310. Since the case assembly 400 slides in a straight line and the relative position between the above two inductors 310 is known, the moving direction of the key assembly 400 can be obtained. By comparing the changing trends of the inductance values ​​of any two inductors 310, the sliding direction of the key assembly 400 can be obtained.

[0066] Since the relationship between the distance between the button assembly 400 and the inductor 310 and the inductance value of the inductor 310 is definite and unique, by obtaining the current inductance values ​​of any two inductors 310, the processor 320 of the circuit board 300 can calculate the current position of the button assembly 400 based on the current inductance values ​​of any two inductors 310, and the circuit board 300 can output a signal of the corresponding working parameters to the driver based on the current position of the button assembly 400.

[0067] For example, when there is only one inductor 310, in the sliding direction of the key assembly 400, the inductor 310 can be located at the end of the sliding range of the key assembly 400, so that the moving direction of the key assembly 400 can be obtained through the changing trend of the inductance value of the inductor 310, and the position of the key assembly 400 can be obtained by obtaining the inductance value of the inductor 310.

[0068] In some embodiments of the present invention, Fig. 9 As shown (in the figure, L1 is the change line of the inductance value of the first inductor, and L2 is the change line of the inductance value of the second inductor), the multiple inductors 310 include a first inductor and a second inductor. When the key assembly 400 moves from the first inductor to the second inductor, the inductance value of the first inductor gradually decreases, and the inductance value of the second inductor gradually increases. The circuit board 300 outputs a linearly changing adjustment signal according to the gradually decreasing inductance value of the first inductor and the gradually increasing inductance value of the second inductor.

[0069] For example, when the oral cleaning device 1 is in the minimum gear, the button assembly 400 can be located at the lowest end of the sliding stroke, and the first inductor is located below the second inductor. When the button assembly 400 slides upward, the inductance value of the second inductor gradually decreases and the inductance value component of the first inductor increases. The circuit board 300 obtains the current position and moving direction of the button assembly 400 according to the inductance value of the first inductor and the inductance value of the second inductor, and the adjustment signal changes linearly; when the button assembly 400 slides downward, the inductance value of the second inductor gradually increases and the inductance value component of the first inductor decreases. The circuit board 300 obtains the current position and moving direction of the button assembly 400 according to the inductance value of the first inductor and the inductance value of the second inductor, and the adjustment signal changes linearly.

[0070] In this way, no matter which direction the key assembly 400 slides, the inductance value of the first inductor and the inductance value of the second inductor both undergo continuous linear changes, making the judgment of the circuit board 300 simpler and being able to output continuous signals according to this rule.

[0071] According to some specific embodiments of the present invention, Fig.11 As shown (in the figure, L1 is the change line of the inductance value of the first inductor, L2 is the change line of the inductance value of the second inductor, and L3 is the change line of the inductance value of the third inductor), the multiple inductors 310 include a first inductor, a second inductor and a third inductor which are sequentially arranged in a first direction at intervals. When the key assembly 400 moves from the first inductor to the third inductor, the inductance value of the first inductor gradually decreases, the inductance value of the second inductor first increases and then decreases, and the inductance value of the third inductor gradually increases. The circuit board 300 outputs a linearly changing adjustment signal according to the gradually decreasing inductance value of the first inductor, the first increasing and then decreasing inductance value of the second inductor, and the gradually increasing inductance value of the third inductor.

[0072] In this way, the number of inductors 310 distributed on the sliding stroke of the button assembly 400 can be increased, and the change in the inductance value of each inductor 310 is also linear. The comprehensive induction intensity of multiple inductors 310 is higher, which can further improve the adjustment accuracy.

[0073] According to some specific embodiments of the present invention, the two ends of the multiple inductors 310 in the first direction exceed the sliding travel of the key assembly 400. In this way, when the key assembly 400 slides, the inductance value of at least one inductor 310 must increase, and the inductance value of at least one inductor 310 must decrease, so that the circuit board 300 only needs to obtain the change of the inductance value of the inductors 310 at the two ends to obtain the moving direction of the key assembly 400, which makes it easier to determine the position of the key assembly 400.

[0074] Of course, the sliding travel of the key assembly 400 may also exceed at least one end of the plurality of inductors 310 in the first direction.

[0075] For example, Fig.10 As shown (in the figure, L1 is the change line of the inductance value of the first inductor, and L2 is the change line of the inductance value of the second inductor), when the multiple inductors 310 include the first inductor and the second inductor, when the key assembly 400 moves from the first inductor to the second inductor, the inductance value of the first inductor gradually increases, and the inductance value of the second inductor first decreases and then increases; or, when the key assembly 400 moves from the second inductor to the first inductor, the inductance value of the second inductor gradually increases, and the inductance value of the first inductor first decreases and then increases.

[0076] like Fig.10 As shown (in the figure, L1 is the change line of the inductance value of the first inductor, L2 is the change line of the inductance value of the second inductor, and L3 is the change line of the inductance value of the third inductor), when the multiple inductors 310 include a first inductor, a second inductor and a third inductor sequentially arranged in a first direction, when the key assembly 400 moves from the first inductor to the third inductor, the inductance value of the first inductor gradually increases, the inductance value of the second inductor first decreases and then increases, and the inductance value of the third inductor first decreases and then increases; or, when the key assembly 400 moves from the third inductor to the first inductor, the inductance value of the third inductor gradually increases, the inductance value of the second inductor first decreases and then increases, and the inductance value of the first inductor first decreases and then increases.

[0077] In this way, the sliding stroke of the button assembly 400 can be further increased, thereby increasing the range of the gear position and improving the gear position accuracy.

[0078] In some specific embodiments of the present invention, the inductor 310 is a ring structure with a spiral size gradually increasing from one end to the other end, and the two side surfaces of the inductor 310 in the thickness direction are parallel to the surface of the circuit board 300 in the thickness direction.

[0079] The inductor 310 with such a ring structure can generate a stable magnetic field when energized, and because the two side surfaces of the inductor 310 in the thickness direction are parallel to the surface of the circuit board 300 in the thickness direction, the overall size of the circuit board 300 and the inductor 310 in the thickness direction of the circuit board 300 can be reduced, and the button assembly 400 is on one side in the thickness direction of the circuit board 300, so that the button assembly 400 can be closer to the inductor 310, and thus a slight movement of the button assembly 400 can also produce a significant change in the inductance value of the inductor 310, thereby facilitating the change of the working parameters of the driver.

[0080] In some specific embodiments of the present invention, Figure 3 As shown, the key assembly 400 includes a key cap 410 , a connecting rod 430 and a shift sliding member 420 .

[0081] The button cap 410 is exposed from the sliding installation slot 110 so as to be pushed by human hands, which makes it convenient for the user to directly touch the button cap 410 , thereby facilitating the adjustment of the gear position of the oral cleaning device 1 .

[0082] In addition, the connecting rod 430 is connected to the side of the key cap 410 facing the circuit board 300 and extends in the direction of the circuit board 300. The shift sliding member 420 is located between the key cap 410 and the circuit board 300 and is fixed to the shell 100. A connecting member 480 is provided in the shift sliding member 420, and the connecting member 480 is connected to the connecting rod 430.

[0083] In this way, the connecting rod 430 and the gear sliding member 420 can be fixed together through the connecting member 480 , and the gear sliding member 420 can be driven to slide by pushing the button cap 410 during use, thereby facilitating the adjustment of the gear of the oral cleaning device 1 .

[0084] Furthermore, at least one of the key cap 410, the connecting rod 430 and the connecting member 480 is a conductor, wherein the key cap 410 and the connecting rod 430 can be formed as one body. Furthermore, at least one of the key cap 410, the connecting rod 430 and the connecting member 480 can be made of conductive plastic or conductive metal.

[0085] In this way, when the user pushes the button assembly 400 to slide freely, at least a portion of the button assembly 400 can be affected by the magnetic field of the inductor 310 to generate eddy currents. The eddy currents of the button assembly 400 will also affect the size of the magnetic field of the inductor 310 to change the inductance value of the inductor 310, thereby realizing stepless speed regulation of the oral cleaning device 1.

[0086] In some specific embodiments of the present invention, Figure 5-Figure 7As shown, the gear sliding member 420 is provided with a through hole 423, and the through hole 423 includes a first section 424 and a second section 425. The aperture of the second section 425 is larger than the aperture of the first section 424. The second section 425 is connected to the side of the first section 424 away from the button cap 410. The connecting member 480 is located in the second section 425 and stops at the first section 424. The connecting rod 430 extends into the through hole 423 and is connected to the connecting member 480.

[0087] For example, the connecting rod 430 may be provided with an external thread, the connecting member 480 may be provided with an internal thread, the connecting rod 430 and the connecting member 480 may be threadedly connected, or the connecting rod 430 and the connecting member 480 may be glued. The diameter of the connecting rod 430 may be smaller than the hole diameter of the first section 424, and the diameter of the connecting member 480 is not smaller than the diameter of the first section 424 and smaller than the diameter of the second section 425.

[0088] In this way, after the connecting rod 430 passes through the first section 424 and extends into the second section 425, the end of the connecting rod 430 facing the connecting member 480 can be fixed together with the connecting member 480. When the key cap 410 is pulled outward from the shifting space 510, since the first section 424 limits the position of the connecting member 480, the connecting rod 430 will not be separated from the through hole 423, thereby fixing the relative positions of the key cap 410 and the shifting sliding member 420. When the user is controlling the movement of the key cap 410, there is no need to worry about the key cap 410 being separated from the mounting base 500, thereby increasing reliability.

[0089] In some specific embodiments of the present invention, Figure 1 and Figure 4 As shown, the oral cleaning device 1 also includes a mounting seat 500, which is installed on the shell 100 and is located in the sliding mounting groove 110. The mounting seat 500 is provided with a blocking space 510. The blocking sliding member 420 can be slidably installed on the mounting seat 500 and is located in the blocking space 510. The blocking space 510 can limit the blocking sliding member 420. The inductor 310 and the button assembly 400 are located on opposite sides of the mounting seat 500. Specifically, the inductor 310 is located on the side of the mounting seat 500 facing the inside of the shell 100, and the button assembly 400 is located on the side of the mounting seat 500 facing the outside of the shell 100.

[0090] In this way, the mounting base 500 can separate the inductor 310 and the key assembly 400 , and there is no need for direct contact between the inductor 310 and the key assembly 400 , which can prevent the key assembly 400 from touching the inductor 310 when sliding, thereby reducing the probability of damage to the inductor 310 .

[0091] Optionally, the bottom wall and the side wall of the shifting space 510 are integral, and both the bottom wall and the side wall of the shifting space 510 are non-porous structures, that is, there are no holes in the bottom wall and the side wall of the shifting space 510. Therefore, even if there is water in the shifting space 510, it will not flow to the circuit board 300. In this way, the sliding of the shifting sliding member 420 can be realized, and the internal space of the shifting space 510 and the shell 100 can be separated, which has an excellent waterproof effect, thereby preventing the electrical components in the shell 100 (for example, the circuit board 300 and the inductor 310) from short-circuiting due to contact with water, and the electrical connection reliability of the oral cleaning device 1 is high.

[0092] Furthermore, if Figure 2-Figure 4 As shown, the gear space 510 has a first inner wall 511 and a second inner wall 512 relative to each other, the gear sliding member 420 has a first outer wall 421 and a second outer wall 422 relative to each other, the first outer wall 421 faces the first inner wall 511 and the second outer wall 422 faces the second inner wall 512, one of the first outer wall 421 and the first inner wall 511 is provided with a plurality of first gear grooves 440 and the other is provided with at least one first gear protrusion 520, and at least one of the first gear protrusions 520 is fitted into one of the plurality of first gear grooves 440.

[0093] For example, the cross-section of each first gear protrusion 520 and the cross-section of each first gear groove 440 may be arc-shaped, and arc transitions may be used between adjacent first gear grooves 440 , which facilitates the switching of the first gear protrusion 520 within multiple first gear grooves 440 .

[0094] Moreover, when the button assembly 400 is located at one end of the gear space 510, the oral cleaning device 1 can be in a closed state, and when the button assembly 400 slides toward the other end of the gear space 510, the oral cleaning device 1 is turned on and the gear is continuously increased.

[0095] Among them, when the user's finger pushes the button assembly 400 to slide relative to the mounting base 500, the first gear protrusion 520 will come out of a first gear groove 440 and then enter another first gear groove 440, and each first gear protrusion 520 repeats the above process in sequence, that is, the first gear protrusion 520 and the first gear groove 440 are separated - engaged - separated again - engaged again, until the button assembly 400 stops sliding relative to the mounting base 500.

[0096] During the sliding of the button assembly 400 relative to the mounting base 500, the first gear protrusion 520 slides in and out of the first gear slot 440, and the tactile feedback given to the user is quite different. The user can judge whether the current operation is valid based on the tactile feedback of the operation. In addition, when the first gear protrusion 520 continuously slides in and out of the first gear slot 440, the first gear protrusion 520 and the first gear slot 440 will make feedback sounds due to the engagement and separation, such as "da da da" sounds. The user can also judge whether the current operation is valid based on the feedback sounds. In this way, the user can clearly perceive that the button assembly 400 is being controlled based on the dual feedback of sound and tactile feeling, thereby avoiding repeated operations due to uncertainty about whether the operation is valid, and providing a better operating experience.

[0097] Furthermore, if Figure 4 As shown, one of the second outer side wall 422 and the second inner side wall 512 is provided with a plurality of second gear grooves 450 and the other is provided with at least one second gear protrusion 530 , and one second gear protrusion 530 is matched in one of the plurality of second gear grooves 450 .

[0098] Among them, multiple first gear slots 440 are arranged along the sliding direction of the button assembly 400, and multiple second gear slots 450 are arranged along the sliding direction of the button assembly 400. The positions of the multiple first gear slots 440 and the positions of the multiple second gear slots 450 can correspond one to one.

[0099] Specifically, the button assembly 400 is located between the first inner wall 511 and the second inner wall 512, the first gear groove 440 of the first inner wall 511 is recessed from the first inner wall 511 toward the direction away from the second inner wall 512, and the second gear groove 450 of the second inner wall 512 is recessed from the second inner wall 512 toward the direction away from the first inner wall 511, the first gear protrusion 520 of the first outer wall 421 protrudes from the first outer wall 421 toward the direction close to the first inner wall 511, and the second gear protrusion 530 of the second outer wall 422 protrudes from the second outer wall 422 toward the direction close to the second inner wall 512.

[0100] For example, when there is one first gear protrusion 520, it is matched with one of the multiple first gear grooves 440, or when there are multiple first gear protrusions 520, they are matched with different first gear grooves 440; when there is one second gear protrusion 530, it is matched with one of the multiple second gear grooves 450, or when there are multiple second gear protrusions 530, they are matched with different second gear grooves 450.

[0101] It can be understood that the number of the first gear grooves 440 may be greater than the number of the first gear protrusions 520 , and the number of the second gear grooves 450 may be greater than the number of the second gear protrusions 530 .

[0102] In this way, shifting grooves and shifting protrusions are provided on both sides of the button assembly 400, so that the relative sides of the button assembly 400 can be positioned and fixed to the mounting base 500, which is beneficial to improving the stability of the position of the button assembly 400 in the shifting space 510, providing more obvious tactile feedback to the user and better user experience.

[0103] In some specific embodiments of the present invention, Figure 5 As shown, the first gear protrusion 520 includes one provided at the center of the length direction of the first outer wall 421, and the second gear protrusion 530 includes one provided at the center of the length direction of the second outer wall 422. The length direction of the first outer wall 421, the length direction of the second outer wall 422 and the extension direction of the gear space 510 may be parallel.

[0104] The first gear protrusion 520 and the second gear protrusion 530 can be used together to limit the button assembly 400, and the feedback effect is better. The first gear protrusion 520 is set at the center of the length direction of the first outer wall 421, and the second gear protrusion 530 is set at the center of the length direction of the second outer wall 422. The first gear protrusion 520 and the second gear protrusion 530 are at the same distance from the two ends of the length direction of the button assembly 400.

[0105] In other specific embodiments of the present invention, Figure 6 As shown, the first gear protrusion 520 includes two protrusions disposed at both ends of the first outer side wall 421, and the second gear protrusion 530 includes two protrusions disposed at both ends of the second outer side wall 422. In this way, the number of the first gear protrusion 520 and the second gear protrusion 530 is greater, so when the key assembly 400 slides relative to the mounting base 500, the tactile and sound feedback is stronger, and the user can feel the movement of the key assembly 400 more clearly, further optimizing the user's use experience.

[0106] Of course, it can be understood that the above two methods can be applied at the same time, that is, the first gear protrusion 520 includes one provided at the center of the length direction of the first outer wall 421 and two provided at both ends of the first outer wall 421, and the second gear protrusion 530 includes one provided at the center of the length direction of the second outer wall 422 and two provided at both ends of the second outer wall 422. Among them, the first gear protrusion 520 can be symmetrically arranged about the center of the length direction of the first outer wall 421, and the second gear protrusion 530 can be symmetrically arranged about the center of the length direction of the second outer wall 422.

[0107] When the first gear protrusion 520 is set on the first outer wall 421, and the second gear protrusion 530 is set at different positions of the second outer wall 422, the button assembly 400 is subjected to different forces when sliding, and the user also has different feedback tactile sensations when operating, thereby being able to meet the needs of different groups of people.

[0108] In some specific embodiments of the present invention, Figure 5-Figure 7 As shown, the bottom surface of the shift sliding member 420 is provided with at least one first protrusion 460 extending along the sliding direction of the button assembly 400, and at least one first protrusion 460 contacts the bottom wall of the shift space 510, that is, there is a gap fit between the bottom surface of the button assembly 400 and the bottom wall of the shift space 510.

[0109] In this way, the contact area between the bottom surface of the button assembly 400 and the bottom wall of the gear space 510 can be reduced, thereby reducing the friction resistance between the button assembly 400 and the bottom wall of the gear space 510 during sliding, facilitating the sliding of the button assembly 400, and making gear switching more convenient and easy to operate.

[0110] In some specific embodiments of the present invention, Figure 3 As shown, a sealing ring 540 is sleeved on the outer circumference of the mounting seat 500, and the sealing ring 540 abuts against the inner wall of the sliding mounting groove 110, that is, the sealing ring 540 is interference fit with the outer circumference of the mounting seat 500 and the inner wall of the sliding mounting groove 110 to fill the gap between the outer circumference of the mounting seat 500 and the inner wall of the sliding mounting groove 110.

[0111] Since the oral cleaning device 1 comes into contact with water frequently during use, the sealing ring 540 can prevent water and dust from entering the sliding mounting groove 110 through the gap between the outer peripheral surface of the mounting seat 500 and the inner wall of the sliding mounting groove 110, thereby improving the waterproof performance of the oral cleaning device 1, which is beneficial to protecting the reliability of the electrical connection of electrical components such as the circuit board 300 and the driving component.

[0112] In some specific embodiments of the present invention, Figure 1 and Figure 3 As shown, the oral cleaning device 1 further includes a decorative plate 700 .

[0113] The decorative plate 700 is installed on the housing 100 and covers the sliding installation groove 110 . The decorative plate 700 is provided with a through hole 710 penetrating the decorative plate 700 . The button assembly 400 passes through the through hole 710 and slides along the extension direction of the through hole 710 .

[0114] Since the decorative plate 700 serves to shield the sliding mounting groove 110, on the one hand, it can reduce the entry of impurities such as dust and liquid into the shell 100 through the sliding mounting groove 110, thereby ensuring the cleanliness of the interior of the shell 100 and the smoothness of the movement of the button assembly 400. On the other hand, the appearance of the oral cleaning device 1 is more beautiful. In addition, the decorative plate 700 can also limit the button assembly 400 to prevent the button assembly 400 from detaching from the sliding mounting groove 110 under non-human operation.

[0115] In addition, by setting the through hole 710, a moving space can be preset for the connecting rod 430, that is, it plays a guiding role in the movement of the connecting rod 430, and then can guide the sliding of the gear sliding member 420 to avoid the position displacement of the button assembly 400, thereby making it easier for users to adjust the gear of the oral cleaning device 1.

[0116] Alternatively, if Figure 1 and Figure 3 As shown, the oral cleaning device 1 also includes a limiting reinforcement plate 600, and the side of the mounting seat 500 facing away from the circuit board 300 has an opening. The limiting reinforcement plate 600 is installed on the side of the mounting seat 500 facing away from the circuit board 300 and covers the opening, and the top surface of the shifting sliding member 420 stops at the limiting reinforcement plate 600.

[0117] In this way, on the one hand, the limiting reinforcement plate 600 can limit the movement of the shift sliding member 420 in the height direction of the shift sliding member 420, thereby preventing the shift sliding member 420 from leaving the shift space 510; on the other hand, since the button assembly 400 performs reciprocating motion, the shift sliding member 420 needs to be rubbed against the decorative plate 700 multiple times, and the decorative plate 700 is thin and has low strength, so setting the limiting reinforcement plate 600 can avoid contact between the decorative plate 700 and the shift sliding member 420, thereby reducing the chance of damage to the decorative plate 700.

[0118] Among them, the limiting reinforcement plate 600 can be a plastic material with higher strength, such as Saigang material POM (Polyoxymethylene polyoxymethylene resin). In this way, the limiting reinforcement plate 600 is a non-conductor. While ensuring the strength of the limiting reinforcement plate 600, it can avoid the limiting reinforcement plate 600 from affecting the inductance value of the above-mentioned inductor 310, thereby ensuring the accuracy of the inductance value obtained by the circuit board 300, so as to achieve precise control of the driving component.

[0119] Furthermore, if Figure 5-Figure 7 As shown, the top surface of the shift sliding member 420 is provided with at least one second ridge 470 extending along the sliding direction of the button assembly 400, and at least one second ridge 470 abuts against the limiting reinforcement plate 600, that is, there is a clearance fit between the top surface of the button assembly 400 and the limiting reinforcement plate 600.

[0120] In this way, the contact area between the top surface of the shift slide 420 and the limit reinforcement plate 600 can be reduced, thereby reducing the friction resistance between the shift slide 420 and the limit reinforcement plate 600 during the sliding process, facilitating the sliding of the button assembly 400, and making the shifting more convenient and easy to operate.

[0121] In some specific embodiments of the present invention, Figure 1 and Figure 3 As shown, the oral cleaning device 1 further includes a first fixing member 610 and a second fixing member 620 .

[0122] The inner circumference of the sliding mounting groove 110 is provided with a mounting platform 120, the outer circumference of the mounting seat 500 is provided with a ring platform 550, and the first fixing member 610 and the second fixing member 620 are arranged at intervals along the circumference of the limiting reinforcement plate 600. For example, the first fixing member 610 and the second fixing member 620 can be arranged at both ends of the length of the mounting seat 500, that is, the first fixing member 610 and the second fixing member 620 are located at both ends of the length of the limiting reinforcement plate 600.

[0123] In this way, the first fixing member 610 and the second fixing member 620 can provide multiple fixing points for the mounting base 500 and the limiting reinforcement plate 600 from both ends of the mounting base 500, so that the fixation is more reliable.

[0124] Specifically, the first fixing member 610 and the second fixing member 620 are installed on the mounting platform 120 through the ring platform 550 and the limiting reinforcing plate 600 to fix the limiting reinforcing plate 600, the mounting seat 500 and the housing 100. The first fixing member 610 and the second fixing member 620 can be bolts.

[0125] In this way, the relative positions of the limiting reinforcement plate 600, the mounting seat 500 and the shell 100 can be avoided, the first inner side wall 511 and the second inner side wall 512 of the shifting space 510 can limit the position of the shifting slide 420 in the width direction of the shifting slide 420, and the bottom wall of the limiting reinforcement plate 600 and the mounting seat 500 can limit the position of the shifting slide 420 in the height direction of the shifting slide 420, so as to fix the position of the shifting slide 420 and avoid the shifting slide 420 from leaving the shifting space 510.

[0126] Other structures and operations of the oral cleaning device 1 according to the embodiment of the present invention are known to those skilled in the art and will not be described in detail here.
