[0051] The following will, with reference to the accompanying drawings, elaborate on some embodiments of the present application. Without conflict, the following embodiments and the features in the embodiments may be combined with each other.

[0052] Please refer to Figure 1 , an oral cleaning device 1000 is provided in an embodiment of the present application. The oral cleaning device 1000 can clean the oral cavity, for example, it can clean teeth. The oral cleaning device 1000 may include an electric toothbrush, a manual toothbrush, or other devices capable of cleaning the oral cavity. The following will take the oral cleaning device 1000 as an electric toothbrush as an example for illustration.

[0053] Please refer to Figure 1 and Figure 2 , in some embodiments, the oral cleaning device 1000 includes a brush head 100 and a brush handle 200, and the brush head 100 is connected to the brush handle 200. Exemplarily, when the oral cleaning device 1000 includes an electric toothbrush, the brush head 100 is connected to the brush handle 200 to drive the brush head 100 to vibrate or move through the brush handle 200, thereby completing the cleaning of the oral cavity. When the oral cleaning device 1000 includes an electric toothbrush, the brush head 100 can be connected to the brush handle 200 to facilitate the user to drive the electric toothbrush to act by holding the brush handle 200, thereby completing the brushing action. It can be understood that the brush head 100 can be applied to an electric toothbrush or a manual toothbrush, or can be used independently.

[0054] In some embodiments, the oral cleaning device 1000 further includes a driving member (not shown in the figure). The driving member can drive the cleaning member 40 to move, thereby cleaning the oral cavity. Exemplarily, the driving member includes a vibration motor, and the vibration generated by the vibration motor can be transmitted to the brush head 100, thereby cleaning the oral cavity. Exemplarily, the driving member includes a driving motor, and the driving motor can drive the cleaning member 40 of the brush head 100 to rotate, thereby cleaning the oral cavity.

[0055] Please refer to Figures 3 to 5, in some embodiments, the brush head 100 includes a brush rod 10, a brush plate 20, a connecting member 30, a cleaning member 40, and a protruding structure 50. The brush rod 10 includes a rigid member 11, and the rigid member 11 includes a first connecting section 111 and a second connecting section 112. The second connecting section 112 is used to connect to the brush handle 200 of the oral cleaning device 1000, and the first connecting section 111 is connected to one end of the second connecting section 112 away from the connection with the brush handle 200; the brush plate 20 is connected to the first connecting section 111; the connecting member 30 is connected to the brush plate 20; the cleaning member 40 is connected to the connecting member 30, and the cleaning member 40 is used to clean the oral cavity. Among them, a protruding structure 50 is provided between the connecting member 30 and the brush plate 20, and the protruding structure 50 protrudes from at least one of the brush plate 20 and the connecting member 30, so that the connecting member 30 can be welded to the brush plate 20 through the protruding structure 50.

[0056] For the oral cleaning device 1000 of the above embodiment, since a protruding structure 50 is provided between the connecting member 30 and the brush plate 20, and the protruding structure 50 protrudes from at least one of the brush plate 20 and the connecting member 30, so that the connecting member 30 can be welded to the brush plate 20 through the protruding structure 50, thereby realizing a reliable connection between the connecting member 30 and the brush plate 20, improving the connection strength between the connecting member 30 and the brush plate 20, effectively reducing the probability that the connecting member 30 and the brush plate 20 are difficult to be effectively connected and thus easily separated, and improving the user experience.

[0057] Please refer to Figure 6 and Figure 7 , in some embodiments, the protruding structure 50 protrudes from the connecting member 30, and the protruding structure 50 is welded to the brush plate 20; or, the protruding structure 50 protrudes from the brush plate 20, and the protruding structure 50 is welded to the connecting member 30. The protruding structure 50 can be integrally formed and connected to the connecting member 30, and the protruding structure 50 is welded to the brush plate 20; or, the protruding structure 50 can be integrally formed and connected to the brush plate 20, and the protruding structure 50 is welded to the connecting member 30. When the number of the protruding structures 50 includes a plurality, the plurality of protruding structures 50 can all protrude from the connecting member 30 or the brush plate 20; or, at least one of the plurality of protruding structures 50 protrudes from the connecting member 30, and the remaining protruding structures 50 protrude from the brush plate 20.

[0058] Exemplarily, the protruding structure 50 protrudes from the connecting member 30. When welding, at least one of the protruding structure 50 and the brush plate 20 is melted, for example, the protruding structure 50 is melted to achieve welding, that is, the connecting member 30 is welded to the brush plate 20 through the protruding structure 50. Exemplarily, the protruding structure 50 protrudes from the brush plate 20. When welding, at least one of the protruding structure 50 and the connecting member 30 is melted, for example, the protruding structure 50 is melted to achieve welding, that is, the connecting member 30 is welded to the brush plate 20 through the protruding structure 50.

[0059] In some embodiments, the connecting member 30 is ultrasonically welded or laser welded to the brush plate 20 through the protruding structure 50, so as to effectively improve the connection reliability between the connecting member 30 and the brush plate 20 and enhance the user experience. Exemplarily, ultrasonic welding, also known as ultrasonic bonding, is commonly used for welding thermoplastic plastic products. Ultrasonic energy is transmitted to the welding area through one of the workpieces, and local high temperature is generated due to the large acoustic resistance at the welding interface of the two workpieces, causing the two workpieces to fuse together.

[0060] In some embodiments, after the connecting member 30 is welded to the brush plate 20 through the protruding structure 50, the protruding height of the protruding structure 50 ranges from 0.1 mm to 0.4 mm. For example, the protruding height of the protruding structure 50 is 0.1 mm, 0.3 mm, 0.4 mm, or any other suitable value between 0.1 mm and 0.4 mm. After the connecting member 30 is welded to the brush plate 20 through the protruding structure 50, if the protruding height of the protruding structure 50 is too small, it may cause over-welding during the welding process and damage at least one of the connecting member 30, the cleaning member 40, and the brush plate 20; if the protruding height of the protruding structure 50 is too large, it may cause unstable welding, making it difficult for the connecting member 30 to be reliably connected to the brush plate 20. In this embodiment, after the connecting member 30 is welded to the brush plate 20 through the protruding structure 50, the protruding height of the protruding structure 50 ranges from 0.1 mm to 0.4 mm, which can minimize the damage to at least one of the connecting member 30, the cleaning member 40, and the brush plate 20 during the welding process, and enable the connecting member 30 to be reliably welded to the brush plate 20 through the protruding structure 50, improving the connection strength and connection reliability between the connecting member 30 and the brush plate 20.

[0061] Exemplarily, the protruding structure 50 protrudes from the connecting member 30; before the connecting member 30 is fusion-connected to the brush plate 20 through the protruding structure 50, the range of the protruding height of the protruding structure 50 protruding from the connecting member 30 is 0.5 mm - 2 mm. For example, the protruding height of the protruding structure 50 protruding from the connecting member 30 is 0.5 mm, 1 mm, 1.5 mm, 2 mm or any other suitable value between 0.5 mm - 2 mm. Thus, even if the height of the connecting member 30 increases after the cleaning member 40 is heat-melted to the connecting member 30, the protruding structure 50 can still be higher than other non-fusion-connected areas of the connecting member 30 or the brush plate 20 during the fusion connection, which is beneficial to ensuring the reliable connection between the connecting member 30 and the brush plate 20 and can minimize the damage to the brush plate 20 or the cleaning member 40 as much as possible. Exemplarily, the protruding structure 50 protrudes from the brush plate 20. Before the connecting member 30 is fusion-connected to the brush plate 20 through the protruding structure 50, the range of the protruding height of the protruding structure 50 protruding from the brush plate 20 is 0.2 mm - 1 mm. For example, the protruding height of the protruding structure 50 protruding from the brush plate 20 is 0.2 mm, 0.5 mm, 1 mm or any other suitable value between 0.2 mm - 1 mm. Thus, even if the height of the connecting member 30 increases after the cleaning member 40 is heat-melted to the connecting member 30, the protruding structure 50 can still be higher than other non-fusion-connected areas of the connecting member 30 or the brush plate 20 during the fusion connection, which is beneficial to ensuring the reliable connection between the connecting member 30 and the brush plate 20 and can minimize the damage to the brush plate 20 or the cleaning member 40 as much as possible. It can be understood that the degree of fusion can be determined by the protruding height of the protruding structure 50 before and after the fusion connection. If, after the connecting member 30 is fusion-connected to the brush plate 20 through the protruding structure 50, the protruding height of the protruding structure 50 is greater than 0.4 mm, it can be determined that the fusion is not in place; if, after the connecting member 30 is fusion-connected to the brush plate 20 through the protruding structure 50, the protruding height of the protruding structure 50 is less than 0.1 mm, it can be determined that the fusion is excessive and the brush plate 20 or the cleaning member 40 may be damaged during the fusion connection process.

[0062] Please refer to Figure 7In some embodiments, the protruding structure 50 is protruded from the connecting member 30, and the protruding structure 50 is fused and connected to the brush plate 20; the connecting member 30 is formed with a through hole 31 for inserting the cleaning member 40, and the protruding structure 50 and the through hole 31 are staggered. The protruding structure 50 and the through hole 31 are staggered, so that on the one hand, the strength of the protruding structure 50 can be improved, the fusion strength can be strengthened, and the connection strength between the connecting member 30 and the brush plate 20 can be improved; on the other hand, during the connection process of the cleaning member 40 and the connecting member 30, the staggered setting of the protruding structure 50 and the through hole 31 can avoid the protruding structure 50, avoid damaging the protruding structure 50 during the connection process of the cleaning member 40 and the connecting member 30, avoid affecting the effect of the fusion connection, and help ensure that the connecting member 30 is reliably connected to the brush plate 20. The cleaning member 40 and the connecting member 30 can be fixed together by high-temperature melt adhesive or any other suitable fixing method. When the cleaning member 40 is fixed to the connecting member 30 by high-temperature melt adhesive or any other suitable fixing method, the height of the melt adhesive is not higher than the protruding height of the protruding structure 50 to avoid affecting the effect of the fusion connection. Exemplarily, the number of the through holes 31 can be set according to actual needs, such as one, two, three or more. The shape of the through hole 31 can be set according to actual needs, such as square, round, waist-shaped, other regular shapes or irregular shapes. When the number of the through holes 31 includes multiple, the shapes and / or sizes of the multiple through holes 31 can be the same or different.

[0063] See also Figure 7 and Figure 8 In some embodiments, the connector 30 includes a first surface 32 facing the brush plate 20, and the protruding structure 50 is arranged at the outer edge of the first surface 32. In this way, the connector 30 is well welded to the brush plate 20 through the protruding structure 50; the protruding structure 50 is not easy to interfere with the connection between the connector 30 and the cleaning member 40 during the connection between the cleaning member 40 and the connector 30. In other embodiments, the protruding structure 50 can also be arranged at any other suitable position of the first surface 32, which is not limited here. Exemplarily, the connector 30 also includes a second surface 33 and a side wall surface 34, the second surface 33 is arranged opposite to the first surface 32, and the side wall surface 34 connects the first surface 32 and the second surface 33. The through hole 31 passes through the first surface 32 and the second surface 33. In other embodiments, the through hole 31 is arranged on the second surface 33, the through hole 31 is recessed from the second surface 33 toward the first surface 32, and the through hole 31 does not pass through the first surface 32.

[0064] See also Figure 7 In some embodiments, the shape of the protruding structure 50 includes a ring shape to improve the effect of the fusion connection. In other embodiments, the shape of the protruding structure 50 can also be other shapes, such as an arc shape, other regular shapes or irregular shapes.

[0065] See alsoFigures 6 to 8 , in some embodiments, the number of the protruding structures 50 includes at least two. The at least two protruding structures 50 include a first protruding structure 51 and a second protruding structure 52, and the first protruding structure 51 and the second protruding structure 52 are arranged at intervals. The welding connection between the connecting member 30 and the brush plate 20 is realized through the first protruding structure 51 and the second protruding structure 52, greatly improving the effect of the welding connection, and thus effectively improving the connection reliability between the connecting member 30 and the brush plate 20. The first protruding structure 51 and the second protruding structure 52 are arranged at intervals, which can reduce the material usage of the protruding structure 50 while improving the connection reliability between the connecting member 30 and the brush plate 20 as much as possible.

[0066] Please refer to Figure 7 and Figure 8 , in some embodiments, the first protruding structure 51 is farther from the middle of the connecting member 30 than the second protruding structure 52, that is, the first protruding structure 51 is arranged outside the second protruding structure 52. The second protruding structure 52 arranged inside is used to strengthen the effect of the welding connection of the first protruding structure 51 arranged outside, thereby further improving the effect of the welding connection and improving the connection strength and connection reliability between the connecting member 30 and the brush plate 20. Exemplarily, the first protruding structure 51 extends from the side of the side wall surface 34 close to the first surface 32 in a direction away from the second surface 33.

[0067] In some embodiments, the first protruding structure 51 and the second protruding structure 52 are symmetrical structures. In this way, the effect of the welding connection is better, which is beneficial to improving the connection strength and connection reliability between the connecting member 30 and the brush plate 20.

[0068] In some embodiments, the first protruding structure 51 and the second protruding structure 52 protrude from the side of the connecting member 30 facing the brush plate 20 at intervals. The end of the first protruding structure 51 facing the brush plate 20 is flush with the end of the second protruding structure 52 facing the brush plate 20; or, the protruding height of the first protruding structure 51 is 0-0.2 mm higher than the protruding height of the second protruding structure 52, so as to ensure that the first protruding structure 51 can be fully melted during the welding connection, thereby providing a guarantee for the connecting member 30 and the brush plate 20 to have good connection strength and connection reliability.

[0069] Exemplarily, the first connecting section 111 and the second connecting section 112 are integrally formed and connected to reduce the number of components of the brush head 100, which is beneficial to improving the processing efficiency of the brush head 100. Exemplarily, the thickness of the first connecting section 111 is greater than the thickness of the brush plate 20. Exemplarily, the thickness of the brush plate 20 refers to the thickness along Figure 4 the X direction in

[0070] Understandably, the brush plate 20 can enter the human oral cavity when the oral cleaning device 1000 is operating, so that the connecting member 30 can enter the human oral cavity, and further enable the cleaning member 40 provided on the connecting member 30 to clean the oral cavity. Exemplarily, the brush rod 10 and the brush plate 20 are integrally injection molded, that is, the brush plate 20 and the first connecting section 111 are integrally injection molded, so as to reduce the number of components, reduce the processing steps, and improve the processing efficiency of the brush head 100. Exemplarily, the brush plate 20 is generally flat and sheet-shaped, and the end of the brush plate 20 away from the brush rod 10 is arc-shaped to prevent damage to the oral cavity during cleaning. Exemplarily, the hard member 11 and / or the brush plate 20 are made of hard materials to improve the transmission efficiency. Exemplarily, the hard member 11 and / or the brush plate 20 can be prepared from plastic materials such as acrylonitrile-butadiene-styrene (ABS) or polycarbonate (PC),

[0071] Please refer to Figure 3 and Figure 4 , in some embodiments, the brush rod 10 further includes a soft member 12, and the soft member 12 wraps at least part of the hard member 11 and at least part of the brush plate 20. The soft member 12 can prevent the relatively hard brush plate 20 from colliding with the skin or teeth in the oral cavity when the user uses the oral cleaning device 1000, causing discomfort, and improving the user experience.

[0072] When the soft member 12 wrapped outside the hard member 11 and / or the brush plate 20 collides with the inner wall of the oral cavity (such as teeth or gums, etc.) in the oral cavity, since the soft member 12 is a flexible structure, the soft member 12 can play a buffering role, reducing the force of the brush head 100 colliding with the skin or teeth in the oral cavity, and preventing the relatively hard brush plate 20 and the hard member 11 from directly touching the gums, teeth or other positions of the oral cavity during use, improving the user experience. Exemplarily, the hardness of the soft member 12 is less than the hardness of the brush plate 20 and / or the hard member 11. Exemplarily, the soft member 12 is coated on the outside of the hard rubber member and / or the brush plate 20 through a secondary injection molding process; or, the soft member 12 is coated on the outside of the brush plate 20 and / or the brush plate 20 through a two-color injection molding process; or, the soft rubber member is coated on the outside of the hard rubber member and / or the brush plate 20 through a co-injection molding process. The soft member 12 can be prepared from at least one soft material such as thermoplastic elastomer (TPE), thermoplastic polyurethane elastomer (TPU), rubber material, silica gel, etc.

[0073] In some embodiments, the thickness of the soft member 12 ranges from 0.4 mm to 1.2 mm, for example, the thickness of the soft member 12 is 0.4 mm, 0.8 mm, 1.2 mm or any other suitable value between 0.4 mm and 1.2 mm. In this way, the force of the brush head 100 colliding with the skin or teeth in the oral cavity during vibration or movement can be effectively reduced, improving the experience of the user during oral care; and the material usage of the soft member 12 can be reduced.

[0074] Understandably, the soft member 12 is too soft to well cover the hard member 11 and the brush plate 20, and air bubbles are likely to be generated during the covering process. If the soft member 12 is too hard, it cannot produce a good shock-absorbing effect. In some embodiments, the hardness of the soft member 12 ranges from 35° to 70°, such as 35°, 50°, 70° or any other suitable value between 35° and 70°, so as to balance the good covering effect and the shock-absorbing effect.

[0075] Exemplarily, the cleaning member 40 includes bristles or other flexible cleaning members 40. Exemplarily, the cleaning member 40 includes a plurality of bristles, and the plurality of bristles form a bristle bundle. At least one bristle bundle is connected to the connecting member 30. The bristles can be inserted into the connecting member 30 through the through holes 31. When there are multiple bristle bundles, the multiple bristle bundles are connected to the connecting member 30 at intervals. In other words, there is an interval between adjacent bristle bundles, and this interval provides a space for the bending of adjacent bristle bundles, facilitating the deformation of the bristle bundles according to the shape of the oral cavity, so that the bristle bundles can better fit the teeth, etc., and at the same time, it is also convenient to clean the food residues between adjacent bristle bundles.
