[0048] The toothbrush head according to an embodiment of the present invention and a toothbrush having the same will be described in detail below with reference to the accompanying drawings.

[0049] Refer to Figures 1 to 4 As shown, the toothbrush head according to an embodiment of the present invention includes a brush base 10, a floating body 20 and bristles 30. Among them, the brush base 10 can be made of plastic material with a certain hardness, and the brush base 10 has a hollow opening H10.

[0050] The floating body 20 is located within the hollow opening H10 and is connected to the brush base 10. The floating body 20 can elastically float within the hollow opening H10. That is to say, the floating body 20 is connected in the hollow opening H10 of the brush base 10 and has a certain elasticity. When subjected to a force, it can elastically deform in the thickness direction of the brush base 10 within the hollow opening H10.

[0051] The bristles 30 are arranged on the lower surfaces of the brush base 10 and the floating body 20. That is, the bristles 30 are arranged on the lower surfaces of both the brush base 10 and the floating body 20. When brushing teeth with this toothbrush head, when the bristles 30 on the brush base 10 and the floating body 20 come into contact with the teeth in the oral cavity and the bristles 30 are slightly pressed against the teeth with a little force, the bristles 30 on the floating body 20 receive the pressure from the teeth and thus force the floating body 20 to deform outwardly towards the oral cavity. In this way, the bristles 30 on the floating body 20 are not easily bent but remain upright and in contact with the teeth. Briefly speaking, this elastic floating structure design of the floating body 20 enables the bristles 30 of this toothbrush head to have better adaptability to the teeth of the user.

[0052] For the toothbrush head according to an embodiment of the present invention, a hollow opening H10 is provided on the brush base 10, and a floating body 20 is provided within the hollow opening H10. The floating body 20 can elastically float. In this way, when the bristles 30 are in contact with the teeth for brushing, the acting force of the teeth on the middle part of the bristles 30 causes the floating body 20 to elastically deform towards the outer side of the oral cavity, thereby keeping the middle part of the bristles 30 in contact with the teeth and not bent, and further making the friction sufficient during toothbrushing and the cleaning effect better.

[0053] Preferably, the circumferential direction of the hollow opening H10 is closed, that is to say, the hollow opening H10 is a through-hole structure with a circumferentially closed structure. Such a structural design can make other parts of the brush holder 10 maintain better integrity, thereby ensuring that the bristles 30 on the brush holder 10 are in close contact with the teeth during use, and during the brushing action, the actions of various parts of the entire toothbrush head are more consistent, and the brushing effect is better.

[0054] In an embodiment of the present invention, the floating body 20 includes a carrier part 201 and a connecting part 202. Among them, the carrier part 201 is located within the hollow opening H10, and the bristles 30 are arranged on the carrier part 201; one end of the connecting part 202 is connected to one side surface of the carrier part 201, and the other end of the connecting part 202 is connected to the inner wall of the hollow opening H10.

[0055] That is to say, the floating body 20 is mainly composed of a carrier part 201 and a connecting part 202. The carrier part 201 is used for installing and arranging the bristles 30, and the connecting part 202 connects the carrier part 201 to the brush holder 10. During use, the bristles 30 on the carrier part 201 are subjected to the pressure of the teeth, thereby forcing the carrier part 201 and the connecting part 202 to deform towards the outer side of the oral cavity. Due to the existence of the connecting part 202, the carrier part 201 can be deformed more easily, and the elastic deformation amount is also larger. Furthermore, it can ensure that the force of the teeth on the bristles 30 can force the carrier part 201 to float towards the outer side of the oral cavity. In addition, this connection method has a simple and reliable structure and low cost.

[0056] In an embodiment of the present invention, the hollow opening H10 includes a first hollow area H101 and a second hollow area H102. Among them, the carrier part 201 is located in the first hollow area H101. The second hollow area H102 is in communication with the first hollow area H101, and the width of the second hollow area H102 is smaller than the width of the first hollow area H101. The connecting part 202 is formed in a strip shape and is located in the second hollow area.

[0057] That is to say, the hollow opening H10 is mainly composed of a first hollow area H101 and a second hollow area H102. The width of the first hollow area H101 is relatively wide and is adapted to the carrier part 201, while the width of the second hollow area H102 is relatively narrow and is adapted to the connecting part 202. Preferably, the width of the first hollow area H101 is 2 to 5 times the width of the second hollow area H102. Exemplarily, the carrier part 201 is formed in a generally square shape, and the connecting part 202 is formed in a strip shape. The carrier part 201 is located in the first hollow area H101, and the connecting part 202 is located in the second hollow area H102. The strip-shaped connecting part 202 is used to connect the carrier part 201 to the brush holder 10.

[0058] In this embodiment, the connecting portion 202 is configured as a strip structure and arranged in the adapted second hollow area H102. In this way, such a strip-shaped connecting portion 202 can provide a larger elastic deformation amount and is more likely to undergo elastic deformation. In addition, its structure is simple, facilitating the connection between the carrier portion 201 and the brush base 10.

[0059] Preferably, the floating body 20 and the brush base 10 are made of the same plastic material, and the connecting portion 202, the carrier portion 201 and the brush base 10 are formed as a whole. That is to say, the carrier portion 201, the connecting portion 202 and the brush base 10 are an integrally formed structure, for example, through an injection molding process, injection molded at one time. In this way, the process and structure are simpler. In addition, the structure is more reliable and stable, and has higher strength.

[0060] Advantageously, the first hollow area H101 and the second hollow area H102 are arranged side by side in the length direction of the brush base 10. In this way, it can be ensured that the first hollow area H101 has a relatively larger size, and the second hollow area H102 can extend along the length direction of the brush base 10 to form a strip, thereby ensuring that the connecting portion 202 has a larger length dimension and a larger deformation amount.

[0061] It can be understood that the connecting portion 202 is not limited to one, and the connecting portion 202 can be two or more. A plurality of connecting portions 202 can ensure that the connection between the carrier portion 201 and the brush base 10 is more reliable and the force is more evenly distributed.

[0062] In an embodiment of the present invention, the second hollow area H102 is located at the middle position in the length direction of the brush base 10, and at least part of the bristles 30 on the carrier portion 201 protrude downward relative to the adjacent bristles 30 on both sides.

[0063] That is to say, the carrier portion 201 is located at the middle position in the length direction of the brush base 10, and at least part of the bristles 30 on the carrier portion 201 are longer than the adjacent bristles 30 on both sides, and thus their lower ends protrude from the adjacent bristles 30. In this embodiment, configuring at least part of the bristles 30 on the carrier portion 201 to be longer can enable this part of the downwardly protruding bristles 30 to extend into the tooth gaps for effective cleaning of the tooth gaps. Compared with the arrangement of equal-length bristles 30 on traditional toothbrushes, it has a better cleaning effect, especially facilitating the cleaning of tooth gaps.

[0064] Exemplarily, there are multiple rows of bristles 30 on the carrier portion 201, among which, one or two rows of bristles 30 in the middle are longer than the bristles 30 on both sides. In this way, it is convenient to clean the tooth gaps by using one or two rows of bristles 30 in the middle.

[0065] More advantageously, the hardness of at least part of the bristles 30 on the carrier part 201 is greater than that of the other bristles 30. In this way, the bristles 30 with greater hardness have a better cleaning effect when cleaning the interdental spaces.

[0066] In some embodiments of the present invention, the lower ends of the bristles 30 on the brush base 10 and the floating body 20 together form a brushing surface, and the brushing surface is formed into a concave arc shape that is concave upward. The part of the bristles 30 on the carrier part 201 is located in the middle of the brushing surface and protrudes downward.

[0067] That is to say, the brushing surface is generally a concave arc structure, and part of the bristles 30 on the carrier part 201 protrude downward from the middle position of the concave arc. In this way, when brushing teeth, the concave arc-shaped brushing surface adheres better to the tooth surface, and part of the protruding bristles 30 on the carrier part 201 can be properly placed in the interdental spaces. During the process of sliding up and down, effective cleaning of the tooth surface and interdental spaces can be achieved. In other words, in this embodiment, by using a concave arc-shaped brushing surface, the fitting degree of the bristles 30 to the tooth surface can be improved, and part of the bristles 30 protruding on the carrier part 201 can adapt to the interdental spaces. Therefore, the overall cleaning effect of the toothbrush can be improved.

[0068] Advantageously, the upper surface of the floating body 20 is slightly lower than the upper surface of the brush base 10. During use, when the bristles 30 on the carrier part 201 are subjected to the pressure of the teeth and thus force the carrier part 201 to deform outward toward the oral cavity, the carrier part 201 is not easily protruded from the upper surface of the brush base 10 or the protruding height is not large. In this way, the use experience of this toothbrush head is better, and there will be no bad use feeling caused by the deformation and protrusion of the carrier part 201.

[0069] The toothbrush according to an embodiment of the present invention includes a toothbrush handle and the toothbrush head as described in the above embodiment. One end of the toothbrush handle is connected to the toothbrush head, and the toothbrush handle is a manual handle or an electric handle. That is to say, this toothbrush head can be used for an ordinary manual toothbrush or an electric toothbrush.

[0070] The toothbrush provided according to an embodiment of the present invention has the above toothbrush head. Therefore, the middle part of the bristles 30 can be kept in contact with the teeth without bending, so that the friction is sufficient during toothbrushing and the cleaning effect is better.

[0071] It can be understood that in some embodiments of the present invention, at least part of the area on the toothbrush head is wrapped with a soft rubber material. Exemplarily, the outer peripheral surface of the brush base 10 is wrapped with a soft rubber material. In this way, problems such as damage to the gums caused by touching the gums can be prevented. Or, the upper surface of the brush base 10 is provided with a soft rubber material, and there are several dot-like protrusions on the soft rubber material. In this way, the tongue can be brushed through the soft rubber material and the dot-like protrusions, achieving the effect of tongue cleaning.
