[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0033] like Figures 1 to 7 As shown, an oral care element according to the present application includes a main body 10 , a contact element carrier, a first contact element cluster 41 and a second contact element cluster 42 .

[0034] The main body 10 includes a proximal end 11 and a distal end 12 extending along the main body axis, and the distal end 12 is used to couple with the driving assembly. The contact element carrier is located on the support member 111, and the contact element carrier includes a first carrier 21, and a second carrier 22 connected to the first carrier 21 through an elastic member 30, and multiple groups of second carriers 22 and elastic members 30 are arranged at intervals on the side of the first carrier 21. The support member 111 is maintained at the proximal end 11 and at least partially supports the contact element carrier. The contact element carrier has a front surface 211, and the first carrier 21 has a first channel 51 connected to the front surface 211, and the second carrier 22 has a second channel 52 connected to the front surface 211. The first contact element cluster 41 passes through the first channel 51 and extends from the front surface 221. The second contact element cluster 42 passes through the second channel 52 and extends from the front surface 211. When the second contact element cluster 42 is subjected to force, the second carrier 22 is suitable for swinging relative to the first carrier 21 with the elastic member 30 as a swing arm.

[0035] By using the technical solution of this embodiment, the first carrier 21 can swing relative to the proximal end 11 of the main body 10, the second carrier 22 can swing relative to the first carrier 21, and the plurality of second carriers 22 are connected to the first carrier 21 by independent elastic members 30, and each second carrier 22 can swing independently relative to the first carrier 21. The tooth surface in the oral cavity has an arc, and there is a depression or gap between two adjacent teeth. When the first contact element cluster 41 and the second contact element cluster 42 are used to clean the teeth, the force magnitude and direction of the ends of each first contact element cluster 41 and the second contact element cluster 42 will be different. The force received by the second contact element cluster 42 can be transmitted to the second carrier 22, and each second carrier 22 can swing relative to the first carrier 21 with the corresponding elastic member 30 as the swing arm according to its own force condition. Each second contact element cluster 42 can naturally adjust its posture so that its respective end is in close contact with the surface to be cleaned, providing the overall first contact element cluster 41 and the second contact element cluster 42 with the tooth surface, thereby improving the cleaning effect. At the same time, by adjusting the position of the end of the second contact element cluster 42 when it is pressed, the pressure of the second contact element cluster 42 on the teeth or gums can be reduced, thereby protecting the teeth or gums and improving the comfort of the oral care element.

[0036] like Figure 1 As shown, the main body is generally a rod-shaped structure, which can be a hollow rod or a solid rod. Figure 3 In the direction shown, the proximal end 11 of the body 10 is Figure 1 The upper end of the main body 10 is Figure 1 The proximal end 11 and the distal end 12 can be understood as the end close to the oral cavity and the end away from the oral cavity during the use of the main body 10.

[0037] Furthermore, the distal end 12 of the main body 10 is used to couple with the driving mechanism, and the proximal end 11 of the main body 10 is used to install the contact element carrier. Therefore, when the driving mechanism is started and vibrates, the main body 10 can transmit the vibration of its distal end 12 to the proximal end 11, and then transmit the vibration to the contact element carrier through the support member 111.

[0038] In addition, the outer diameter of the distal end 12 of the main body 10 is greater than the outer diameter of the proximal end 11, which can enhance the structural strength of the distal end 12 of the main body 10 on the one hand and enhance the vibration transmission effect on the other hand.

[0039] like Figure 1As shown, the support member 111 is plate-shaped, and the contact element carrier is roughly a flat elliptical structure. The function of the contact element carrier is to install the above-mentioned first contact element cluster 41 and the second contact element cluster 42. The contact element carrier includes a first carrier 21 and a second carrier 22, the first contact element cluster 41 is installed on the first carrier 21, and the second contact element cluster 42 is installed on the second carrier 22. When the driving mechanism is started to generate vibration, the main body 10 transmits the vibration of its distal end 12 to the proximal end 11, and the vibration of the proximal end 11 of the main body 10 is transmitted to the contact element carrier through the support member. The vibration of the contact element carrier drives the first contact element cluster 41 and the second contact element cluster 42 to swing back and forth at a high speed. The user places the contact element carrier in the oral cavity, and the first contact element cluster 41 and the second contact element cluster 42 are in contact with the gums or teeth, thereby achieving a cleaning effect.

[0040] In one implementation of the present embodiment, the outer contour line of the support member 111 coincides with the outer contour line of the first carrier 21, and the support member 111 can mainly support the first carrier 21. Although the swinging ability of the first carrier 21 is reduced to a certain extent, the second carrier 22 is not affected by the support member 111, thereby ensuring the swinging amplitude of the second carrier 22 relative to the first carrier 21, thereby allowing the second contact element cluster 42 to better fit the surface of the teeth or gums.

[0041] like Figure 1 As shown, in another implementation of this embodiment, at least part of the orthographic projection of the contact element carrier is located within the orthographic projection of the support member 111. Figure 1 At the angle shown, the orthographic projection is made in a direction perpendicular to the front surface of the contact element carrier, and the orthographic projection is made in a direction perpendicular to the surface of the support 111. The orthographic projection of the contact element carrier is located within the orthographic projection of the support 111, that is, the support 111 can provide support for both the first carrier 21 and the second carrier 22. Under this structure, there is a certain gap between the support 111 and the contact element carrier, and the gap is the movement space for the second carrier 22 to swing downward relative to the first carrier 21, thereby ensuring that the support 111 can provide good support for the contact element carrier, and can also ensure that the second carrier 22 can swing relative to the first carrier 21.

[0042] For example, the support member 111 can only support the first carrier 21, or the support member 111 can support the first carrier 21 and part of the second carrier 22, so that the second carrier 22 has a larger free movement space, and when the user uses the oral care element to clean the oral cavity, the second contact element cluster 42 can flexibly fit the oral tissue after being stressed. Of course, the support member 111 can also support the first carrier 21 and all the second carriers 22 to improve the stability of the oral care element. Moreover, there is no connection structure between the second carriers 22, which ensures the freedom of independent swing of each second carrier 22.

[0043] In the above two supporting methods, the contact element carrier or part of the contact element carrier can be tightly connected to the support member 111, or the contact element carrier or part of the contact element carrier can be connected to the support member 111 through a fixing member, so that there is a gap between the contact element carrier or part of the contact element carrier and the support member 111, and the gap can be used as a movement space for the first carrier 21 and / or the second carrier 22.

[0044] from Figure 1 It can be seen that the front surface 211 of the contact element carrier refers to the surface facing the teeth or gums during cleaning. The first carrier 21 has a first channel 51 connected to the front surface 211, and the first contact element cluster 41 extends from the first channel 51. The first contact element cluster 41 is formed by a plurality of first contact elements being bundled together. The first channel 51 can enhance the bundling effect of the plurality of first contact elements. The second carrier 22 has a second channel 52 connected to the front surface 211, and the second contact element cluster 42 extends from the second channel. The second contact element cluster 42 is formed by a plurality of second contact elements being bundled together. The second channel 52 can enhance the bundling effect of the plurality of second contact elements. The end of the first contact element cluster 41 and the second contact element cluster 42 refers to the end facing the same direction as the front surface 211. The ends of the first contact element cluster 41 and the second contact element cluster 42 can jointly form a cleaning surface for cleaning teeth or gums. The second carrier 22 located on both sides of the first carrier 21 can swing with the elastic member 30 as a swing arm, so that the second contact element cluster 42 can swing relative to the first contact element cluster 41, so that the cleaning surface can change according to the shape of the tooth or gum surface, better fit the tooth or gum surface, and improve the cleaning effect of the cleaning surface.

[0045] like Figure 3 As shown, one end of the elastic member 30 is connected to the edge of the first carrier 21 , and the other end is connected to the edge of the second carrier 22 . The first carrier 21 and the second carrier 22 can be made of hard materials, and the second carrier 22 can swing relative to the first carrier 21 through the elastic member 30 .

[0046] In this embodiment, the cross-sectional shape of the elastic member 30 may be U-shaped or S-shaped. The elastic member 30 may be formed of an elastic material, and the elastic force of the elastic member 30 may be increased by configuring the elastic member 30 to be U-shaped or S-shaped.

[0047] like Figure 4 The schematic diagram of the cross-sectional structure of the second carrier 22 and the elastic member 30 is shown, and the cross-section of the elastic member 30 is set to S shape for illustration, and the top and bottom of the elastic member 30 are connected to the edges of the first carrier 21 and the second carrier 22 respectively. When the second contact element cluster 42 is subjected to pressure from the teeth or gums, the second contact element cluster 42 transmits the pressure to the second carrier 22, and the second carrier 22 swings downward with the elastic member 30 as the rotation axis under the action of the pressure. At the same time, the elastic force of the elastic member 30 can prevent the second carrier 22 from continuing to swing downward. The elastic force increases with the swing amplitude of the second carrier 22, and then the second carrier 22 can be provided with a supporting force to promote the end of the second contact element cluster 42 to be pressed against the teeth or gums, and the friction between the second contact element cluster 42 and the surface of the teeth or gums is increased, so that the end of the second contact element cluster 42 can swing in accordance with the shape of the teeth and maintain effective cleaning force. In this embodiment, the elastic force of the elastic member 30 is increased by increasing the actual length of the elastic member 30 and the stacking density, thereby ensuring the cleaning effect. Similarly, the same technical effect can be achieved by adopting a U-shaped design of the elastic member 30 .

[0048] In addition, arranging the elastic member 30 in a U-shape or an S-shape can also reduce the spacing distance between the second carrier 22 and the first carrier 21, so that the structure of the contact element carrier is more compact, which can ensure the cleaning power and reduce the size.

[0049] like Figure 4 As shown, 1 / 2 of the spacing distance between the second carrier 22 and the first carrier 21 is greater than the thickness of the elastic member 30. The thickness of the elastic member 30 refers to the thickness of the cross section perpendicular to the extension direction of the elastic member 30. The spacing distance between the second carrier 22 and the first carrier 21 corresponds to the orthographic projection length of the elastic member 30 from top to bottom. Such a configuration can ensure that the elastic member 30 has good elasticity. If the thickness of the elastic member 30 is too large, the elastic force will be too large, which will make it difficult for the second carrier 22 to swing relative to the first carrier 21.

[0050] like Figure 3 , Figure 5 and Figure 6 As shown in FIG. 1 , the arrangement directions of two adjacent elastic members 30 located on the same side of the first carrier 21 are opposite. Figure 3Taking the left side shown as an example, a total of five second carriers 22 and five elastic members 30 are provided, and each elastic member 30 is defined as an elastic member A, an elastic member B, an elastic member C, an elastic member D and an elastic member E. Taking the elastic member 30 being provided in an S shape as an example, the elastic member A, the elastic member C and the elastic member E are connected to the first carrier 21 and the second carrier 22 in the same manner, and the elastic member B and the elastic member D are connected between the first carrier 21 and the second carrier 22 in the same manner.

[0051] like Figure 5 As shown in FIG. 1 , when the elastic member A, the elastic member C and the elastic member E are connected between the first carrier 21 and the second carrier 22 in an S shape, that is, the lower ends of the elastic members A, the elastic member C and the elastic member E are connected to the second carrier 22, and the upper ends are connected to the first carrier 21, and the elastic member B and the elastic member D are connected between the first carrier 21 and the second carrier 22 in opposite directions symmetrically up and down, that is, as shown in FIG. Figure 6 As shown, the lower ends of the elastic member B and the elastic member D are connected to the first carrier 21, and the lower ends are connected to the second carrier 22. In this way, the setting directions of the two adjacent elastic members 30 are opposite, so that the two adjacent second carriers 22 have different swing amplitudes, thereby facilitating the two adjacent second contact element clusters 42 to better fit the corresponding teeth or gum surfaces, thereby improving the cleaning effect.

[0052] By the same token, when the shape of the elastic member 30 is U-shaped, the openings of the elastic members A, C and E face upward, and the two ends of the openings are connected to the first carrier 21 and the second carrier 22 respectively; the openings of the elastic members B and D face downward, and the two ends of the openings are connected to the first carrier 21 and the second carrier 22 respectively.

[0053] Similarly, the elastic member 30 may be arranged on the right side of the first carrier 21 in the same manner.

[0054] like Figure 3 As shown, in this embodiment, the end of the first carrier 21 is provided with a second carrier 22 connected by an elastic member 30. The elastic member 30 has the same shape and setting as described above. The left and right sides of the first carrier 21 in this embodiment are symmetrically designed, and the left and right sides of the first carrier 21 are arc-shaped, that is, the end size of the first carrier 21 is small. In order to avoid the second carrier 22 located at the end of the first carrier 21 from interfering with the adjacent second carrier 22, the design size can be increased proportionally on the basis of the original elastic member 30, and the specific size can be determined according to actual conditions. With such a setting, the end and both sides of the contact element carrier can have deformation ability, and then the second contact element cluster 42 located at the end and both sides of the contact element carrier can swing to adapt to the shape of the teeth or gums, further improving the fit between the second contact element cluster 42 and the teeth or gums, and improving the cleaning effect.

[0055] In this embodiment, the second carrier 22 is cylindrical, and the outer contour of the cross section can be a circle, a triangle, a rhombus, or a polygon with a side number not less than four. The cross-sectional shape of the second channel 52 can be the same as the outer contour shape of the second carrier 22, and the cross-sectional shape of the second contact element cluster 42 corresponds to the cross-sectional shape of the second channel 52.

[0056] like Figure 7 As shown, the side wall thickness of the second carrier 22 is 0.4 mm to 0.8 mm. The thickness of the second carrier 22 refers to the thickness between the inner and outer walls of the second carrier 22. Figure 7 The thickness D shown in the figure, the side wall thickness of the second carrier 22 can be 0.4mm, 0.5mm, 0.6mm, 0.7mm or 0.8mm. With this configuration, the second carrier 22 can ensure the bundling force on the second contact element cluster 42 and prevent the width of the contact element carrier from being too large. When the side wall thickness of the second carrier 22 is less than 0.4mm, the side wall strength of the second carrier 22 is not strong enough and is easy to break. When the side wall thickness of the second carrier 22 is greater than 0.8mm, the width of the contact element carrier formed is too large.

[0057] like Figure 7 As shown, the height of the second carrier is 1 mm to 3 mm, for example Figure 7 The length L shown in the figure, the height of the second carrier can be 1mm, 1.1mm, 1.2mm... or 3mm. With this arrangement, the second carrier 22 can ensure the bundling force for the second contact element cluster 42 and prevent the height dimension of the contact element carrier from being too large. When the height of the second carrier is less than 1mm, the inner wall of the second carrier 22 cannot provide a good bundling force for the second contact element cluster 42. When the height of the second carrier 22 is greater than 3mm, the height dimension of the formed contact element carrier is too large.

[0058] like Figure 7 As shown, the second channel 52 has an arc surface extending toward the bottom edge of the second carrier 22. As described above, the second contact element cluster 42 is composed of a plurality of second contact elements. In the production process, the plurality of second contact elements are pushed into the second channel 52 by a jig. The arc surface has a guiding function, and can gather the plurality of second contact elements at the edge along the inclined surface into the second channel 52, thereby increasing the density of the second contact elements to improve the cleaning power of the second contact element cluster 42.

[0059] Similarly, the first channel 51 has an arc surface extending toward the bottom edge of the first carrier 21 , which can also increase the density of the first contact elements and improve the cleaning power of the first contact element cluster 41 .

[0060] Furthermore, in this embodiment, the arc surface extends from the top of the second channel 52 to the bottom edge of the second carrier 22, and increasing the length of the arc surface is conducive to guiding the movement of the second contact element. Alternatively, the top of the second channel 52 is a vertical wall surface, and the arc surface extends from the bottom of the vertical wall surface to the bottom edge of the second carrier 22. In this arrangement, the arc surface can guide the movement of the second contact element, and the vertical wall surface can be used to increase the focusing force on multiple second contact elements to ensure the cleaning force.

[0061] Similarly, the arc surface extends from the top of the first channel 51 to the bottom edge of the first carrier 21 , or the top of the first channel 51 is a vertical wall, and the arc surface extends from the bottom of the vertical wall to the bottom of the first carrier 21 .

[0062] like Figure 7 As shown, in one implementation of this embodiment, the angle formed between the tangent direction of the arc surface and the extension direction of the second channel 52 is in the range of 15° to 65°. Since there are many tangent points to choose from on the arc surface, the tangent points can be selected from top to bottom on the arc surface, and the corresponding angle m also increases accordingly. The arc surface in this embodiment is to ensure that when the jig pushes the second contact element toward the second channel 52, the second contact element at the edge can be gathered toward the second channel 52 for guidance. Therefore, it is necessary to ensure that when the optimal point of the arc surface close to the bottom edge of the second channel 52 is the tangent point, the angle m formed between the tangent and the extension direction of the second channel 52 along the height direction is in the range of 15° to 65°, thereby ensuring that the arc surface can play an effective guiding role. When the angle is less than 15°, the movement of the second contact element in the gathering direction cannot be effectively guided. When the angle is greater than 65°, the arc surface is too flat and cannot ensure that the second contact element at the edge is guided toward the direction close to the second channel 52.

[0063] Preferably, the angle formed between the tangent direction of the arc surface and the extending direction of the second channel 52 is in the range of 20° to 45°. Within this range, the density of the formed second contact element cluster 42 can be better ensured.

[0064] In another embodiment, the angle range of this embodiment can be a range of variation in which multiple angles m are formed between multiple tangents from top to bottom on the same arc surface and the extension direction of the second channel 52, that is, a minimum angle and a maximum angle are formed at the edge of the arc surface. The minimum angle in this embodiment is greater than 15°, and the maximum angle is less than 65°. This makes it easier for multiple second contact elements located at the bottom edge of the second carrier 22 to gather toward the second channel 52 under the advancement of the fixture, thereby increasing the density of the second contact element cluster 42.

[0065] The bottom of the first channel 51 also has a curved surface, which is arranged in the same manner as the second channel 52 and can achieve the same technical effect.

[0066] like Figure 1 and Figure 2 As shown, Figure 2 Shown in Figure 1 On the basis, after the first contact element cluster 41 is pushed into the first channel 51, the first contact element cluster 41 is hot-melted at the bottom of the first channel 51. After the second contact element cluster 42 is pushed into the second channel 52, the second contact element cluster 42 is hot-melted at the bottom of the second channel 52. Specifically, after the first contact element cluster 41 is pushed into the first channel 51, most of the first contact element cluster 41 is exposed on one side of the front surface 211, and a shorter length of the first contact element cluster 41 will be left at the bottom of the first channel 51. The bottom of the first contact element cluster 41 can be heated by a hot melt process using an ironing plate until it melts, and then it will be sintered into a sheet structure. The size of the formed sheet structure is larger than the inner diameter of the first channel 51, so that the first contact element cluster 41 will not continue to move in the direction of the front surface 211, avoiding the first contact element cluster 41 from detaching from the first channel 51 during the cleaning process. And through such an implantation method, copper-free hair transplantation can be achieved, avoiding the metal oxidation problem of metal-containing toothbrushes, and avoiding damage to the user's oral health. The bottom of the second contact element cluster 42 can also use the same hot-melt process to form a sheet-like structure at the bottom of the second channel 52, which has the same technical effect as above.

[0067] In one implementation of this embodiment, the bottoms of the plurality of first contact element clusters 41 are melted together to form a first connecting piece, and the bottoms of the plurality of second contact element clusters 42 on the same side are melted together to form a second connecting piece. Figure 3 In the direction shown, the bottoms of the plurality of first contact element clusters 41 can jointly form a first connecting sheet, thereby enabling the bottoms of adjacent first contact element clusters 41 to form a mutually constrained relationship, thereby increasing the pull-off force of the first contact element clusters 41, that is, further preventing the first contact element clusters 41 from falling off from the first channel 51. Figure 3 In the direction shown, the bottom of the plurality of second contact element clusters 42 located on the left side of the first carrier 21 forms a second connecting piece, and the bottom of the plurality of second contact element clusters 42 located on the right side of the first carrier 21 forms another second connecting piece, thereby increasing the pulling force of the second contact element clusters 42.

[0068] like Figure 1 and Figure 2As shown, in another implementation of this embodiment, the bottoms of the plurality of first contact element clusters 41 and the bottoms of the plurality of second contact element clusters 42 are heat-fused together to form a third connecting sheet 60. In this way, the production process can be simplified, and the bottoms of all the first contact element clusters 41 and the second contact element clusters 42 can be melted together into a sheet structure, and the pull-off force of the first contact element clusters 41 and the second contact element clusters 42 can be further increased. The applicant has experimentally measured that the pull-off force can reach 1.5 kg.

[0069] Considering that in the above two embodiments, the first connecting sheet, the second connecting sheet or the third connecting sheet will cause the two adjacent first contact element clusters 41 or the two adjacent second contact element clusters 42 to be entangled with each other during movement, the bottoms of the corresponding first contact element clusters 41 and / or the second contact element clusters 42 can be melted into sheets according to different groups according to actual needs. Of course, the corresponding second contact element clusters 42 and the bottoms of the first contact element clusters 41 can also be melted and connected into a tree shape according to the extension direction of the elastic member, roughly according to Figure 3 The layout of the first channel 51 and the second channel 52 shown in the figure connects the bottoms of the adjacent first contact element clusters 41 and the second contact element clusters 42 by fusion bonding, and the bottoms of two adjacent first contact element clusters 41 are fusion bonded, thereby forming a tree-like connecting sheet.

[0070] Furthermore, on the basis of the third connecting piece 60, a notch can be cut in the third connecting piece 60 at the bottom of two adjacent second carriers 22, thereby greatly releasing the restraining relationship between the bottoms of two adjacent second contact element clusters 42, and improving the freedom of the second carrier 22 to swing independently relative to the first carrier 21, so that the second contact element cluster 42 can better fit the corresponding tooth or gum surface.

[0071] refer to Figure 1 and Figure 2 In this embodiment, the oral care element includes an elastic soft glue 70, which wraps a part of the surface of the contact element carrier and a part of the surface of the support member, and does not exceed the front surface 211 of the contact element carrier at the highest.

[0072] After the first contact element cluster 41 and the second contact element cluster 42 are respectively implanted into the corresponding first channel 51 and the second channel 52, the contact element carrier and the support member 111 can be placed in the jig for injection, thereby forming an elastic soft glue 70 that wraps around part of the surface of the contact element carrier and part of the surface of the support member. For example, the elastic soft glue 70 at least wraps around the bottom surface of the support member 111, thereby preventing the support member 111 from directly contacting the user's oral cavity and causing discomfort. The elastic soft glue 70 does not exceed the front surface 211 of the contact element carrier at the highest, avoiding direct contact between the elastic soft glue 70 and the first contact element cluster 41 and the second contact element cluster 42, which affects the cleaning effect. .

[0073] In one implementation of this embodiment, the elastic soft glue 70 wraps at least part of the bottom surface of the support member 111, and the bottom surface and at least part of the side surface of the second carrier 22. That is, when the support member 111 only supports the first carrier 21, the size of the support member 111 can be made small, so the bottom of the support member 111 and the side wall of the second carrier 22 are easy to contact the user's mouth, and the elastic soft glue 70 wraps the bottom surface of the support member 111 and the bottom surface and side surface of the second carrier 22, and the soft glue directly contacts the user's mouth instead of the above structure, which can improve the user's comfort.

[0074] In another implementation of the present embodiment, the elastic soft adhesive 70 wraps at least part of the bottom surface of the support member 111 and at least part of the side surface of the contact element carrier. When the size of the support member 111 is enlarged to support the first carrier 21 and the second carrier 22, the bottom surface and edge of the support member 111 will be in direct contact with the oral cavity when the user cleans the mouth. The elastic soft adhesive 70 wraps the bottom surface and side surface of the support member 111. The elastic soft adhesive 70 can replace the bottom surface and side surface of the support member 111 to contact the user's oral cavity, thereby improving the user's comfort.

[0075] In the above two embodiments, the elastic soft glue 70 will not enter the gap between the support member 111 and the contact element carrier, so as to avoid the elastic soft glue 70 hindering the swing of the first carrier 21 and / or the second carrier 22 .

[0076] For example, when the size of the support member 111 is reduced and only the first carrier 21 or part of the first carrier 21 is supported, the first carrier 21 and the support member 111 are tightly connected or have a gap, or the first carrier 21 and the connecting piece formed by sintering the first contact element cluster 41 at its bottom are tightly connected / have a gap with the support member, and the elastic soft glue 70 only wraps the bottom surface of the support member 111 and the bottom surface and side surface of the second carrier 22, that is, there is no direct contact between the elastic soft glue 70 and the first carrier 21 and the connecting piece formed by sintering the first contact element cluster 41 at its bottom.

[0077] For example, when the size of the support member 111 is enlarged so as to be able to support the first carrier 21 and part of the second carrier 22, the first carrier 21, the second carrier 22 and the support member 111 are tightly connected or have a gap therebetween, or the first carrier 21 and the connecting piece formed by the sintering of the upper first contact element cluster 41 at its bottom, the second carrier 22 and the connecting piece formed by the sintering of the first contact element cluster 41 at its bottom, and the support member are tightly connected or have a gap therebetween, and the elastic soft glue 70 only wraps around the bottom and side surfaces of the support member 111, and there is no direct contact between the elastic soft glue 70 and the first carrier 21, the second carrier 22 and the connecting piece formed at the bottom of the two.

[0078] refer to Figure 1 and Figure 2 In this embodiment, the spacing between two adjacent second carriers 22 is 0.5mm to 2mm. This arrangement can ensure that adjacent and spaced second carriers 22 do not interfere with each other in motion to a great extent, and can ensure the filling amount of soft glue between two adjacent second carriers 22, thereby ensuring the ability of the two second carriers 22 to swing relative to the first carrier 21 through the elastic member 30. When the spacing between two adjacent second carriers 22 is less than 0.5mm, the soft glue filling amount between two adjacent second carriers 22 is small, and it is impossible to ensure that the second carrier 22 can swing freely relative to the first carrier 21. When the spacing between two adjacent second carriers 22 is greater than 2mm, the second carriers 22 are too sparsely arranged, and the corresponding second contact element clusters 42 are also too sparsely arranged, reducing the cleaning effect.

[0079] In this embodiment, there is a gap between the contact element carrier and the support member 111, and the size of the gap is greater than 0.5 mm. The elastic soft glue 70 is not injected into the gap. In this way, sufficient movement space can be left between the first carrier 21 and its bottom connecting piece formed by the sintering of the upper first contact element cluster 41, the second carrier 22 and its connecting piece formed by the sintering of the first contact element cluster 41, and the support member 111, so as to ensure the freedom of the first carrier 21 and the second carrier 22 to swing, and avoid the elastic soft glue 70 from hindering the swing of the first carrier 21 and the second carrier 22.

[0080] In this embodiment, the main body 10 and the contact element carrier are injection molded separately, so that the contact element carrier as a whole can swing relative to the main body 10, thereby improving the fit between the first contact element cluster 41 and the second contact element cluster 42 and the teeth or gums.

[0081] The present application also provides an electric oral care appliance. The embodiment of the electric oral care appliance according to the present application includes the above-mentioned oral care element and a gripping portion. The gripping portion includes a housing for gripping, a driving component, an energy element, and a triggering element arranged inside the housing. The driving component is coupled with the oral care element of the above-mentioned embodiment. If the triggering element is triggered, the energy element provides energy to the driving component so that the driving component drives the oral care element to vibrate back and forth.

[0082] Furthermore, the electric oral care appliance in this embodiment is an electric toothbrush. The driving component may be a motor, the energy element may be a battery, and the trigger element may be a manual switch.

[0083] When the user uses the electric toothbrush, he turns the manual switch, and the battery supplies power to the motor. When the motor starts, the housing is driven to vibrate. The vibration of the housing is transmitted to the main body 10 and the contact element carrier at the end of the main body 10. When the contact element carrier vibrates, the first contact element cluster 41 and the second contact element cluster 42 are driven to swing at high speed. The user places the contact element carrier in the oral cavity to clean the oral cavity.

[0084] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
