[0044] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0045] Please refer to the following: Figure 1-3 This application provides an electric toothbrush 1 for cleaning a user's oral cavity. The electric toothbrush 1 includes a housing 10, a mounting bracket 20, a motor 30, a display screen 40, and a first buffer 50.

[0046] The housing 10 serves as the external component of the electric toothbrush 1, allowing the user to hold or squeeze it for convenient use. The housing 10 has a receiving cavity 10a for accommodating other components of the electric toothbrush 1. The housing 10 also has a viewing window 10b connected to the receiving cavity 10a, which is used for emitting light from the display screen 40.

[0047] The mounting bracket 20 serves as a support component within the accommodating cavity 10a. The mounting bracket 20 is disposed within the accommodating cavity 10a to protect the mounting bracket 20 through the housing 10. The mounting bracket 20 is used to support other components of the electric toothbrush 11. The mounting bracket 20 can be directly connected to the inner wall of the housing 10, i.e., the cavity wall of the accommodating cavity 10a, or it can be indirectly connected.

[0048] The motor 30 serves as a power output component. The motor 30 is located inside the accommodating cavity 10a and mounted on the mounting bracket 20. The motor 30 has an output shaft 301, which extends out of the housing 10 from the accommodating cavity 10a. That is, the output shaft 301 is used to output the vibration of the motor 30 to the brush head of the electric toothbrush 1 outside the housing 10 (not shown in the figure).

[0049] The display screen 40 serves as the display component of the electric toothbrush 1. The display screen 40 is disposed within the accommodating cavity 10a and mounted on the side of the mounting bracket 20 facing the inner surface of the housing 10, so as to allow light to be emitted from the housing 10. Furthermore, the two opposite sides of the display screen 40 are respectively positioned facing the motor 30 and the viewing window 10b. That is, the back of the display screen 40 is positioned facing the motor 30, rather than offsetting the display screen 40 and the motor 30 along the axial direction of the motor 30. This reduces the length of the electric toothbrush 1 along the axial direction of the motor 30 and also reduces the impact of the vibration of the motor 30 on the display screen 40. Moreover, the display surface of the display screen 40 is positioned facing the viewing window 10b, which facilitates the emission of light from the display screen 40 through the viewing window 10b and reduces the impact of the housing 10 on the light emission of the display screen 40.

[0050] Since both the motor 30 and the display screen 40 are mounted on the mounting bracket 20, the vibration generated by the motor 30 during operation will be transmitted to the display screen 40 through the mounting bracket 20, causing the display screen 40 to vibrate as well. High-frequency vibration not only affects the stability of the display screen 40 on the mounting bracket 20 but also its display effect. Prolonged vibration can easily damage the display screen 40. Therefore, in some embodiments, a first buffer 50 is sandwiched between the display screen 40 and the mounting bracket 20 (this first buffer 50 is not shown in the figure). The first buffer 50 is always in a compressed state to reduce the vibration transmitted from the motor 30 to the display screen 40 through the mounting bracket 20. In other words, the first buffer 50 can buffer the vibration transmitted from the mounting bracket 20 to the display screen 40, specifically reducing the vibration amplitude of the display screen 40, thereby reducing the vibration energy transmitted to the housing 10, improving the stability of the display screen 40 on the mounting bracket 20, and also improving the display stability of the display screen 40. This makes it easier for users to view the content displayed on the screen and reduces the risk of damage to the display screen 40 due to prolonged and significant vibration.

[0051] Furthermore, because the display screen 40 is close to the inner surface of the housing 10, it may interfere with the inner surface of the housing 10 when vibrating, meaning the display screen 40 may collide with the inner surface of the housing 10, which could easily damage the display screen 40. Also, excessive vibration energy from the display screen 40 is transmitted to the housing 10, reducing the user's comfort when holding or gripping the housing 10. Therefore, in some embodiments, such as... Figure 2As shown, the first buffer 50 is sandwiched between the display screen 40 and the inner surface of the housing 10 to buffer the vibration of the display screen 40 relative to the housing 10. That is, the first buffer 50 can buffer the vibration transmitted from the display screen 40 to the housing 10. Specifically, by reducing the vibration amplitude of the display screen 40, the vibration energy transmitted to the housing 10 is reduced, avoiding direct collision between the display screen 40 and the inner surface of the housing 10. It can also improve the display stability of the display screen 40, making it easier for users to view the content displayed on the display screen 40, and can reduce the vibration of the housing 10, improving the comfort of the user when holding the housing 10.

[0052] It is understandable that the first buffer 50 can be clamped between the display screen 40 and the mounting bracket 20, and also between the display screen 40 and the inner surface of the housing 10. The display screen 40 is clamped between two different first buffers 50, or between different parts of the same first buffer 50. This not only buffers the vibration transmitted from the mounting bracket 20 to the display screen 40, but also buffers the vibration transmitted from the display screen 40 to the housing 10. This provides better shock absorption and cushioning for the display screen 40, better protects the display screen 40, makes the position of the display screen 40 more stable, makes it easier for users to view the display content of the display screen 40, and can further reduce the vibration transmitted to the housing, improving the comfort of users holding or squeezing the housing 10.

[0053] Please refer to the following: Figure 2-4 In some embodiments, the viewing window 10b has an inner window 10b1 on the inner surface of the housing 10 (see...). Figure 4 The first buffer 50 is disposed between the display screen 40 and the inner surface of the housing 10 (see...). Figure 2 To buffer the vibrations transmitted from the display screen 40 to the housing 10, and the first buffer 50 is arranged around the inner window 10b1 (see...). Figure 3 This design not only avoids the first buffer 50 affecting the light output of the display screen 40, but also, by surrounding the inner window 10b1, the first buffer 50 can buffer the vibrations transmitted from the display screen 40 to the housing 10 from various positions along the circumference of the inner window 10b1, thereby improving the buffering effect of the first buffer 50 on the vibrations transmitted from the display screen 40 to the housing 10. Furthermore, the first buffer 50 surrounding the inner window 10b1 can also seal the gap between the display screen 40 and the inner surface of the housing 10, preventing liquid from entering the housing 10.

[0054] Please see Figure 3In some embodiments, the display screen 40 includes a display area 401 and a non-display area 402. The display area 401 is directly opposite to the window 10b and can emit light through the window 10b, so that the actual display portion of the display screen 40 is not blocked by the housing 10 and can achieve full light emission. The non-display area 402 surrounds the display area 401, and at least a portion of the non-display area 402 is directly opposite to the inner surface of the housing 10. The first buffer 50 is disposed between the non-display area 402 and the inner surface of the housing 10. Thus, the first buffer 50 not only does not block the display area 401, but can also directly abut against the non-display area 402, thereby directly buffering the vibration of the display screen 40. Since the non-display area 402 is arranged around the display area 401, the first buffer 50 can buffer the vibration transmitted from the display screen 40 to the housing 10 from various positions in the circumferential direction of the display area 401, that is, various positions in the non-display area 402, thereby improving the buffering effect of the first buffer 50.

[0055] Please refer to the following: Figure 1-3 In some embodiments, a light-transmitting element 60 is also included. The light-transmitting element 60 is connected to the housing 10 and covers the viewing window 10b. In this way, the display screen 40 can emit light normally through the light-transmitting element 60 at the viewing window 10b. Furthermore, the light-transmitting element 60 covering the viewing window 10b can prevent external debris such as liquids, toothpaste foam, oil stains, and dust from entering the viewing window 10b and affecting the display effect of the display screen 40 or causing damage to the display screen 40. Specifically, the light-transmitting element 60 can be light-transmitting glass or light-transmitting resin.

[0056] Please refer to the following: Figure 3-4 In some embodiments, the housing 10 includes a support portion 11, which is disposed within the window 10b and is used to support the light-transmitting element 60. Thus, the support portion 11 can provide stable support for the light-transmitting element 60, and the light-transmitting element 60 is bonded to the inner wall of the window 10b and / or the support portion 11 to cover the window 10b. By bonding, easy installation between the light-transmitting element 60 and the inner wall of the window 10b and / or the support portion 11 can be achieved, and at the same time, the gap between the light-transmitting element 60 and the inner wall of the window 10b and / or the support portion 11 can be sealed to prevent external debris such as liquids, toothpaste foam, oil stains and dust from entering the window 10b and affecting the display effect of the display screen 40 or causing damage to the display screen 40.

[0057] Please refer to the following: Figure 3-5 In some embodiments, the window 10b has an outer window 10b2 on the outer surface of the housing 10, and the light-transmitting element 60 protrudes at least partially from the outer window 10b2. This avoids the window 10b forming an excessively deep groove at the outer window 10b2, preventing dirt from accumulating in the excessively deep groove, thus avoiding the need to clean the difficult-to-clean dirt in the groove, and also avoiding the impact of dirt on the display effect of the display screen 40.

[0058] Please refer to the following: Figure 3-5 In some embodiments, the viewing window 10b has an outer window 10b2 on the outer surface of the housing 10. The surface of the light-transmitting element 60 facing away from the display screen 40 is a curved surface 61 with a central protrusion. The center of the curved surface 61 protrudes beyond the outer window 10b2. This avoids the formation of an excessively deep groove in the viewing window 10b at the outer window 10b2, preventing dirt from accumulating in the groove and avoiding the need to clean the difficult-to-clean dirt in the groove. It also avoids the dirt affecting the display effect of the display screen 40. Furthermore, the four edges of the curved surface 61 are lower than the outer window 10b2 and located within the viewing window 10b, preventing the four edges of the curved surface 61 from being higher than the outer window 10b2 and forming sharp protrusions or edges, thus preventing sharp protrusions or edges from scratching the user. It is also understood that if the four edges of the light-transmitting element 60 are higher than the outer window 10b2, the side of the light-transmitting element 60 that is higher than the outer window 10b2 is more susceptible to stress, which could cause the light-transmitting element 60 to peel off.

[0059] Please refer to general information. Figure 1-3 In some embodiments, the electric toothbrush 1 also includes a soft rubber sleeve 70, which is fitted onto at least the portion of the housing 10 where the light-transmitting element 60 is mounted. In this way, if the electric toothbrush 1 is accidentally dropped, the soft rubber sleeve 70 can protect the light-transmitting element 60. Since the light-transmitting element 60 is supported by fragile and easily cracked light-transmitting glass or light-transmitting resin, the risk of the light-transmitting element 60 being damaged due to falling can be reduced.

[0060] Please see Figure 2-3 In some embodiments, a second buffer 80 is also included. The second buffer 80 is always in a compressed state and is disposed between the mounting bracket 20 and the motor 30 to buffer the vibration transmitted from the motor 30 to the mounting bracket 20, thereby further reducing the vibration transmitted from the mounting bracket 20 to the display screen 40 and further reducing the vibration transmitted from the display screen 40 to the housing 10. Specifically, the first buffer 50 and the second buffer 80 include at least one of foam, spring, and soft rubber. The materials of the first buffer 50 and the second buffer 80 can be the same or different. When the first buffer 50 includes foam, the foam also has a water-absorbing function, further preventing liquid from entering the housing 10 through the gap between the display screen 40 and the housing 10. Figure 2-3 In the embodiment shown, two second buffers 80 are included at both ends along the axial direction of the motor, thereby further increasing the contact area between the second buffers 80 and the motor 30 and the mounting bracket 50, and further improving the shock absorption effect.

[0061] Please see Figure 3-4In some embodiments, the housing 10 includes a window portion 12 and a main body portion 13. The window portion 12 has a viewing window 10b, and the main body portion 13 surrounds the window portion 12. The window portion 12 protrudes relative to the main body portion 13, so that the liquid flowing to the window portion 12 can quickly flow to the main body portion 13, avoiding the liquid from affecting the display effect of the display screen 40. In addition, the window portion 12 and the main body portion 13 have a smooth transition, so that the liquid on the window portion 12 can flow more smoothly to the main body portion 13, and can also avoid sharp protrusions or edges between the window portion 12 and the main body portion 13 from scratching the user.

[0062] Please see Figure 2-3 In some embodiments, the device also includes a circuit board 90 and a flexible circuit board 100. The circuit board 90 is disposed on the mounting bracket 20 and is positioned axially along the motor 30. The circuit board 90 and the display screen 40 are spaced apart, and the display screen 40 and the circuit board 90 are connected by the flexible circuit board 100. Compared with the solution where the circuit board 90 and the display screen 40 are stacked, which increases the radial thickness of the electric toothbrush 1, the circuit board 90 and the display screen 40 are spaced apart axially along the motor 30, which can reduce the radial thickness of the vibrating motor 30 and is beneficial to the miniaturization of the electric toothbrush 1 in the radial direction.

[0063] Please see Figure 3 as well as Figure 6 In some embodiments, the electric toothbrush 1 further includes a rotating shaft 41 and a slotted portion. The slotted portion has a slot 42. The rotating shaft 41 is disposed in one of the motor 30 and the mounting bracket 20, and the slotted portion is disposed in the other of the motor 30 and the mounting bracket 20. The rotating shaft 41 can rotate in the slot 42, so that the motor 30 can deflect relative to the mounting bracket 20. When the motor 30 deflects, it will press the display screen 40 through the mounting bracket 20. The first buffer 50 and the second buffer 80 disposed between the mounting bracket 20 and the display screen 40 provide cushioning to prevent... The display screen 50 was crushed; the pivot part 41 and the slotted part form a pivot structure, the pivot structure connects the mounting bracket 20 and the motor 30, the motor 30 and the brush head of the electric toothbrush 1 form a lever structure with the pivot structure as the fulcrum, with the pivot structure as the boundary, the part of the motor 30 close to the brush head in its own axis is the first lever arm 31, the first lever arm 31 is connected to the brush head through the output shaft 301 of the motor 30, the part of the motor 30 away from the brush head in its own axis is the second lever arm 32, that is, the second lever arm 32 is deeper into the receiving cavity 10a than the first lever arm 31.

[0064] Please see Figure 3 as well as Figure 7In addition, the electric toothbrush 1 also includes a reminder component 110 and an electrical connector 120. The reminder component 110 is electrically connected to the circuit board 90, and the electrical connector 120 is connected to the motor 30. Specifically, the electrical connector 120 is connected to the second lever arm 32. The electrical connector 120 can follow the deflection of the second lever arm 32 to make contact with or separate from the circuit board 90, thereby changing the reminder state of the reminder component 110. Specifically, conductive moving contacts can be provided on the electrical connector 120, and conductive stationary contacts can be provided on the circuit board 90.

[0065] Please see Figure 3 as well as Figure 7 Based on the embodiment of the electric toothbrush 1 including a reminder component 110 and an electrical connector 120, the working process of the electric toothbrush 1 is as follows: During the process of cleaning the oral cavity with the electric toothbrush 1, the user moves the electric toothbrush 1 and presses the brush head of the electric toothbrush 1 onto the teeth. When the external force applied to the brush head by the teeth is greater than a preset value, since the brush head is connected to the first lever arm 31 through the output shaft 301 of the motor 30, the first lever arm 31 deflects relative to the mounting bracket 20 with the rotating shaft structure composed of the rotating shaft 41 and the slot 42 as the fulcrum. Since the first lever arm 31 and the first lever arm 32 are connected to the first lever arm 31 through the output shaft 301 of the motor 30, the first lever arm 31 deflects relative to the mounting bracket 20 with the rotating shaft structure composed of the rotating shaft 41 and the slot 42 as the fulcrum. The second lever arm 32 forms a lever structure through a pivot structure. Therefore, the second lever arm 32 will also deflect. Since the electrical connector 120 is disposed on the second lever arm 32, the second lever arm 32 can drive the electrical connector 120 to deflect around the pivot structure. Since the electrical connector 120 is provided with conductive moving contacts, the moving contacts will also deflect along with the electrical connector 120. Therefore, the distance between the moving contacts and the stationary contacts on the circuit board 90 can be changed, so that the moving contacts contact or separate from the stationary contacts, thereby changing the reminder state of the reminder component 110 connected to the stationary contacts. Specifically, the reminder component 110 may include an optical indicator, or it may include the aforementioned display screen 40, through which reminder information is output.

[0066] It should be noted that when the brush head is subjected to an external force greater than a preset value by the teeth, the moving contact on the electrical connector 120 can switch from being in contact with the stationary contact of the circuit board 90 to being separated from the stationary contact, or vice versa. As long as there is a state switching process and a changing electrical signal is provided to the circuit board, the circuit board can control the reminder component 110 to perform the corresponding reminder function based on this changing electrical signal. The specific manifestation of the reminder state is not limited, and the preset value can also be adjusted. For example, the reminder state can be designed so that when the contact state between the moving and stationary contacts changes, the circuit board 90 determines that the user has pressed the brush head against the teeth with too much force. In this case, the reminder state outputs one of the following: a sound prompt signal, a light prompt signal, or a vibration prompt signal, to remind the user that the current pressing force on the electric toothbrush 1 is too high.
