Technical Field
[0001] This invention relates to the field of toothbrushes, and in particular to a replacement head for an electric toothbrush with a bristle-removing mechanism. Background Technology
[0002] Toothbrushes, as a cleaning product, have become indispensable in modern households. Most existing toothbrushes have bristles arranged side-by-side or in a circular pattern, a simple arrangement that only cleans the regular tooth surfaces and lacks specificity for different areas of the mouth, such as between teeth, grooves, and the wisdom tooth area, resulting in limited cleaning ability. Furthermore, the bristles of existing electric toothbrush heads are typically higher on the sides and lower in the middle, failing to effectively clean the wisdom tooth area or the gaps and grooves between teeth, resulting in insufficient cleaning power. Additionally, the vertically arranged bristles of existing electric toothbrushes cannot effectively clean the tiny gaps between teeth, making them prone to bacterial growth. Summary of the Invention
[0003] The main objective of this invention is to provide a replacement head for an electric toothbrush with a bristle-removing mechanism, which aims to improve the cleanliness of brushing teeth.
[0004] To achieve the above objectives, the present invention proposes a replacement head for an electric toothbrush with a bristle-removing mechanism, the replacement head comprising:

[0027] Toothbrushes, as a cleaning product, have become indispensable in modern households. Most existing toothbrushes have bristles arranged side-by-side or in a circular pattern, a simple arrangement that only cleans the regular tooth surfaces and lacks specificity for different areas of the mouth, such as between teeth, grooves, and the wisdom tooth area, resulting in limited cleaning ability. Furthermore, the bristles of existing electric toothbrush heads are typically higher on the sides and lower in the middle, failing to effectively clean the wisdom tooth area or the gaps and grooves between teeth, resulting in insufficient cleaning power. Additionally, the vertically arranged bristles of existing electric toothbrushes cannot effectively clean the tiny gaps between teeth, making them prone to bacterial growth.
[0028] Based on the above reasons, a replacement head for an electric toothbrush with a bristle-removing mechanism is designed, comprising: a brush head base 1, which is used to connect to the toothbrush body 4; and bristles 3, which include a first bristle portion 31, a second bristle portion 32, and a third bristle portion 33, wherein the second bristle portion 32 is arranged around the third bristle portion 33, and the first bristle portion 31 is arranged around the second bristle portion 32, and the first bristle portion 31, the second bristle portion 32, and the third bristle portion 33 are all disposed on the brush head base 1.
[0029] It should be noted that the third bristle portion 33 and the second bristle portion 32 are arranged in a ring around the first bristle portion 31. Under normal circumstances, the outer first bristle portion 31 and the second bristle portion 32 are higher than the middle third bristle portion 33. The third bristle portion 33 is a cylindrical bristle column.
[0030] The brush head includes a first bristle section 31, a second bristle section 32, and a third bristle section 33. The second bristle section 32 is arranged around the third bristle section 33, while the first bristle section 31 is arranged around the second bristle section 32. When using this brush head to brush teeth, the third bristle section 33 in the middle can clean the crevices and gaps between the teeth, while the second bristle section 32 works in conjunction with the third bristle section 33 to clean other parts of the teeth. The two areas of the second bristle section 32 and the third bristle section 33 work together to achieve double cleaning. In this way, some areas that cannot be cleaned by a single bristle section or are not cleaned thoroughly can be cleaned better, thus achieving better oral hygiene.
[0031] Based on the above description, in this embodiment, as Figure 1-3 As shown, the second bristle portion 32 includes a plurality of first cleaning portions 321, which are arranged circumferentially along the brush head base 1. This circumferential arrangement allows for better coordination with the third bristle portion 33, achieving both better cleaning results and a more aesthetically pleasing appearance.
[0032] Furthermore, the first cleaning part 321 includes a first bristle tuft 3211 and a second bristle tuft 3212. The first bristle tuft 3211 is higher than the second bristle tuft 3212, and the first bristle tuft 3211 is disposed in the middle of the second bristle tuft 3212. Both the first bristle tuft 3211 and the second bristle tuft 3212 are disposed on the brush head base 1. The position between the first bristle tuft 3211 and the second bristle tuft 3212 is designed so that when brushing teeth, the first bristle tuft 3211 first touches the teeth. Since the first bristle tuft 3211 is higher than the second bristle tuft 3212, the second bristle tuft 3212 will then touch the teeth for cleaning under the action of pressing. Based on the above analysis, placing the first bristle tuft 3211 in the middle of the second bristle tuft 3212 allows for cleaning around the area cleaned by the first bristle tuft 3211. In particular, when the first bristle tuft 3211 enters the gaps and grooves between teeth for cleaning, the second bristle tuft 3212, directly surrounding the first bristle tuft 3211, can thoroughly clean the entire gap and groove between teeth. Therefore, this structure can achieve more thorough cleaning while maintaining aesthetics.
[0033] Based on the above description, in this embodiment, as Figure 1-3 As shown, the first bristle portion 31 includes a plurality of second cleaning portions 311, which are arranged around the second bristle portion 32. The plurality of second cleaning portions 311 cooperate with the plurality of first cleaning portions 321 to surround the third bristle portion 33. The plurality of second cleaning portions 311 supplement the plurality of first cleaning portions 321, achieving double cleaning of the teeth for a better cleaning effect. At the same time, since the plurality of second cleaning portions 311 and the plurality of first cleaning portions 321 are all arranged around the third bristle portion 33, this arrangement is also more aesthetically pleasing.
[0034] Furthermore, the second cleaning section 311 includes a third bristle tuft 3111 and two fourth bristle tufts 3112. The third bristle tuft 3111 is disposed between the two fourth bristle tufts 3112, and both the third bristle tuft 3111 and the fourth bristle tufts 3112 are disposed on the brush head base 1. The third bristle tuft 3111 and the fourth bristle tufts 3112 work together to achieve a better cleaning effect, and different bristles can be selected in these two areas to achieve different effects.
[0035] Furthermore, the first bristle portion 31 includes a plurality of second cleaning portions 311 and a plurality of third cleaning portions 312, which are spaced apart on the brush head base 1.
[0036] It should be noted that the third cleaning section 312 here can be composed of a single hair tuft, or it can be other hair tufts, as long as it is different from the second cleaning section 311.
[0037] Understandably, the multiple second cleaning parts 311 and the multiple third cleaning parts 312 are spaced apart on the brush head base 1, resulting in a more aesthetically pleasing appearance. Furthermore, the second cleaning parts 311 and the third cleaning parts 312 are different, thus enabling them to achieve different brushing effects. When brushing, the user rotates the toothbrush to allow the second cleaning parts 311 and the third cleaning parts 312 to achieve better cleaning results respectively.
[0038] Based on the above description, in this embodiment, as Figure 1-3 As shown, the first bristle portion 31 is angled along the axis of the brush head base 1, and the second bristle portion 32 is angled along the axis of the brush head base 1. The tilt direction of the second bristle portion 32 is opposite to the tilt direction of the first bristle portion 31. In this case, both the first bristle portion 31 and the second bristle portion 32 are provided with a certain tilt angle, which allows for direct brushing of areas on the teeth that require angled brushing. At the same time, the tilt direction of the second bristle portion 32 is opposite to the tilt direction of the first bristle portion 31, thus ensuring that the bristles are tilted in different directions and angles. This arrangement can achieve a better cleaning effect.
[0039] Furthermore, the tilt angle of the second bristle portion 32 is smaller than that of the first bristle portion 32. The outer tilt angle is larger than the inner tilt angle, which can achieve cleaning at various angles. In practice, the range of the first bristle portion 32 is selected from 0-15°, which can achieve better brushing effect and maintain aesthetics.
[0040] Furthermore, the bristles include pointed bristles and flat bristles. The first bristle section 31, the second bristle section 32, the third bristle section 33, or the more subdivided first bristle tuft 3211, second bristle tuft 3212, third bristle tuft 3111, and fourth bristle tuft 3112 described above can all be replaced with pointed or flat bristles according to actual needs. At the same time, these areas can also use different colors and different heights to achieve both aesthetic appeal and enhanced cleaning ability.
[0041] Furthermore, the electric toothbrush replacement head with bristle removal method also includes a toothbrush head piece 2, which is disposed on the brush head base 1. The toothbrush head piece 2 is provided with a group of through holes, through which the bristles 3 pass and are disposed on the brush head base 1. The toothbrush head piece 2 can be configured to meet the needs of the bristles 3, and can better fix and separate the bottom of the bristles 3.
[0042] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the concept of the present invention, or direct or indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
