[0001] The utility model relates to the field of toothbrushes, in particular to a toothbrush with a whitening function brush head. Background Art

[0002] A toothbrush is a daily oral care tool for cleaning teeth, which is mainly composed of a brush handle and a brush head. During the process of brushing teeth, the bristles on the brush head cooperate with toothpaste to clean the surface of the teeth.

[0003] However, since the tooth surface is not flat, but has concave and convex structures, and there are also concave seams between adjacent teeth, food residues are usually more likely to embed in various concave places and are more difficult to be brushed during brushing. At the same time, the cleaning ability of existing brush heads is low, thereby reducing the oral cleaning ability and teeth whitening ability of toothbrushes. Summary of the invention

[0004] In view of this, the utility model provides a toothbrush with a whitening function brush head, which at least partially solves the problems existing in the prior art.

[0005] According to one aspect of the utility model, a toothbrush with a whitening function brush head is provided, comprising:

[0006] The brush head is a plate-like structure, and the thickness of the brush head is 2.8 mm;

[0007] A brush portion is fixedly arranged on the brush head portion, and the brush portion includes a first brush portion and a second brush portion; the second brush portion is arranged around the first brush portion;

[0008] The diameter of the bristles of the first bristle part is 2 mm, the height is 9 mm, and the material is TPE;

[0009] The diameter of the bristles of the second bristle part is 0.18 mm, the height is 11 mm, and the material is PBT.

[0010] Furthermore, the fixed ends of the bristle filaments of the first bristle portion pass through the brush head portion, and the fixed ends of the bristle filaments of the first bristle portion are fixedly connected to the back side of the brush head portion through the TPE adhesive layer.

[0011] Furthermore, the brush head is a wavy plate structure, and a guide groove is provided in a depression on the surface of the fixed brush part, and the groove depth of the guide groove near the center of the brush head is smaller than the groove depth near the edge of the brush head.

[0012] Furthermore, the guide groove extends in a direction along the width of the brush portion, or in an obliquely upward direction along the width of the brush portion, or in an obliquely downward direction along the width of the brush portion.

[0013] Furthermore, the brush filaments in the brush portion are fixedly arranged on the raised portion of the wavy brush head portion.

[0014] Furthermore, a plurality of flow-conducting holes are provided in the non-bristle connection portion of the brush head along the thickness direction of the brush head.

[0015] Furthermore, it also includes:

[0016] Connect the brush handle and hold the brush handle;

[0017] The connecting brush handle is transitionally connected between the brush head and the holding brush handle;

[0018] The diameter of the brush holding handle is greater than 2.8 mm.

[0019] Furthermore, a plurality of anti-slip grooves are provided on the brush handle.

It should be apparent that the aspects described herein may be embodied in a wide variety of forms, and any specific structure and / or function described herein is merely illustrative. Based on the present disclosure, it should be understood by those skilled in the art that an aspect described herein may be implemented independently of any other aspect, and two or more of these aspects may be combined in various ways. For example, any number of aspects described herein may be used to implement the device and / or practice the method. In addition, other structures and / or functionalities other than one or more of the aspects described herein may be used to implement this device and / or practice this method.

[0040] As an embodiment of the present utility model, Figures 1 to 5 As shown, a toothbrush with a whitening function brush head is provided, comprising: a brush head part 2 and a brush part 1.

[0041] The brush head 2 is a plate-like structure, and the thickness of the brush head 2 is 2.8 mm. Furthermore, the edges of the brush head 2 are all provided with rounded corners. Since the brush head 2 is thinner, in order to prevent damage to the oral cavity during brushing, a softer and smoother rounded corner structure is provided on the edge of the brush head 2.

[0042] The thickness of the brush head 2 in the present invention is further reduced to only 2.8 mm. Compared with the existing brush head thickness (≥3 mm), the brush head 2 of the present invention has a smaller volume, and can more easily and flexibly penetrate into the oral cavity, making it easier to clean the back molars located in the smaller space inside.

[0043] like Figure 1 As shown, the brush portion 1 is fixedly disposed on the brush head portion 2 , and the brush portion 1 includes a first brush portion 10 and a second brush portion 11 ; the second brush portion 11 is disposed around the first brush portion 10 .

[0044] The bristles of the first bristle part 10 have a diameter of 2 mm, a height of 9 mm, and are made of TPE (thermoplastic elastomer).

[0045] The bristles of the first bristle part 10 can be made directly of TPE (thermoplastic elastomer) material or a layer of TPE soft glue can be added to the nylon bristles. Such bristles are not only soft in texture and can better protect the gums, but also have good resilience, which helps to clean deep into the gaps between teeth.

[0046] The bristles of the second bristle portion 10 have a diameter of 0.18 mm, a height of 11.5 mm, and are made of PBT (polybutylene terephthalate).

[0047] Compared with traditional nylon bristles, PBT bristles (brush filaments) have the following characteristics:

[0048] Softness: PBT bristles are softer and can better fit the surface of teeth and gums. They are more friendly to sensitive areas in the mouth and reduce irritation to the gums during brushing.

[0049] Resilience: PBT bristles have good resilience and can quickly return to their original shape even after multiple bends, which helps maintain the effective cleaning force of the bristles and ensure the cleaning effect.

[0050] Wear resistance: Although the hardness of PBT bristles may be slightly lower than that of nylon bristles, its wear resistance is still good and its service life is long.

[0051] Low water absorption: PBT bristles have low water absorption, are less likely to breed bacteria, and are more conducive to oral hygiene.

[0052] Compared with ordinary bristle materials, TPE material has stronger stain removal ability, and in the utility model, TPE bristles are provided with a larger diameter and a lower height, thereby ensuring the stiffness of the TPE bristles themselves, so as to make more complete contact with the teeth during the brushing process, thereby improving the whitening ability of the teeth.

[0053] Further, such as Figure 2 As shown, the fixed end of the bristle of the first bristle part 10 passes through the brush head 2, and the fixed end of the bristle of the first bristle part 10 is fixedly connected to the back of the brush head 2 through the TPE adhesive layer 23. The first bristle part 10 is arranged in the middle of the brush head 2, which can ensure that the setting position of the TPE adhesive layer 23 is also closer to the middle area of ​​the brush head 2. In addition, the thickness of the edge of the brush head 2 will not be affected, and the thickness of the brush head can be further ensured to be as thin as 2.8 mm.

[0054] In addition, the TPE adhesive layer 23 itself also has stronger cleaning ability, which can assist oral cleaning and further improve the whitening ability.

[0055] Thirdly, in order to further improve the cleaning ability of the toothbrush, the height of the multiple brush filaments included in the second bristle portion 11 of the brush portion 1 can also be adjusted so that the non-connected ends of the brush filaments are arranged in a W shape in the length direction of the brush head 2. However, the lowest height of the multiple brush filaments included in the second bristle portion 11 is greater than the height of the brush filaments of the first bristle portion 10.

[0056] In this embodiment, the bristles in the brush part 1 are arranged at different heights, such as Figure 3As shown, after the bristles are fixedly mounted on the brush head, the outer end of the brush portion 1 will present a wave shape (i.e., a W-shape) with high and low staggered settings as a whole. Therefore, when brushing teeth, the longer bristles can go deep into some recesses for cleaning, thereby improving the cleaning ability of the toothbrush.

[0057] As another possible embodiment of the present invention, Figure 3 and Figure 5 As shown, the brush head 2 is a wavy (such as W-shaped) plate-like structure, and a guide groove 22 is opened along the width direction of the brush head 2 in the depression on the surface of the fixed brush part 1, and the groove depth near the center of the brush head 2 in the guide groove 22 is smaller than the groove depth near the edge of the brush head 2.

[0058] Furthermore, a plurality of flow-conducting holes 21 are provided in the non-bristle connection part of the brush head 2 along the thickness direction of the brush head 2. Preferably, the flow-conducting holes 21 are provided in the flow-conducting groove 22.

[0059] Usually after brushing teeth, there will still be water droplets remaining on the bristles of the brush head 2, which will eventually accumulate at the roots along the bristles. A humid environment is more likely to breed bacteria, so in this embodiment, the brush head 2 is also configured as a wavy plate structure, so that water droplets are more likely to gather in the depressions of the wavy structure.

[0060] In this embodiment, a guide groove 22 and / or a guide hole 21 are provided at the concave part, so that the accumulated water droplets can be discharged from the placement surface of the bristles in time, further avoiding the breeding of bacteria. At the same time, the bristles can be fixed at the convex part of the wavy structure to ensure the dryness of the position. In addition, the guide hole 21 can also play a role in ventilation, further improving the dryness of the brush head 2.

[0061] In addition, preferably, the extension direction of the guide groove 22 can be set to be tilted upward or downward along the width direction at a certain angle. Since the toothbrush is basically placed upright or inverted after use, tilting upward or downward along the width direction at a certain angle is also more conducive to the smooth discharge of accumulated water.

[0062] As another possible embodiment of the present invention, Figure 3 to Figure 4 As shown, a toothbrush with a whitening function brush head also includes: a connecting brush handle 3, a holding brush handle 4 and a counterweight.

[0063] The connecting brush handle 3 is transitionally connected between the brush head 2 and the holding brush handle 4. The diameter of the holding brush handle 4 is greater than 2.8 mm. The holding brush handle 4 is provided with a plurality of anti-slip grooves.

[0064] The counterweight block is fixedly connected in a counterweight blind hole 41 opened along the axial direction of the brush handle 4 .

[0065] Specifically, Figure 4 As shown, the counterweight block includes: a connecting column 51 and a counterweight portion 52.

[0066] The connecting column 51 is provided with a thread. It is used for threaded connection with the counterweight blind hole 41. The counterweight part 52 is fixedly connected to the connecting column 51, and one end surface of the counterweight part 52 near the tail of the brush handle 4 is a plane. Preferably, the counterweight part 52 is magnetic. For example, the counterweight part 52 can be made of a magnet with a larger mass.

[0067] Due to the structural design of existing toothbrushes, they are basically unable to be placed vertically by themselves. Usually, they are placed in a tooth cup after use, or directly placed horizontally on other countertops. This placement will cause the toothbrush to come into direct contact with other objects, and the contact area is more likely to accumulate water and breed bacteria.

[0068] In this embodiment, by setting a heavier counterweight at the end of the holding part of the brush handle (i.e., the brush handle 4), the center of gravity of the toothbrush can be further lowered so that it can be placed upright on the table. At the same time, the counterweight part 52 is set to have a magnetic structure, so that the counterweight can be more firmly adsorbed in various existing iron storage racks. The setting of the magnetic structure also enriches the possible placement forms of the toothbrush, which can be placed upright or inverted, thereby further avoiding the contact between the brush head 2 and other parts, thereby ensuring the cleanliness of the brush head.

[0069] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
