Detailed implementation manners
[0026] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0027] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can also be the communication inside two components. It can be a wireless connection or a wired connection. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0028] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0029] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.
[0030] An embodiment of the present utility model discloses a toothbrush head, as Figure 1-7 shown, including: a toothbrush handle 1 and a plurality of toothbrush bristles 2 installed at one end of the toothbrush handle 1. A first accommodation cavity 11 and a second accommodation cavity 12 are provided in the toothbrush handle 1. A circulation hole 13 is provided at one end of the toothbrush handle 1. The circulation hole 13 is located between a plurality of toothbrush bristles 2 and is communicated with the first accommodation cavity 11. The circulation hole 13 is used to discharge gas or liquid.
[0031] It should be noted that since the through-hole 13 is located between several toothbrush bristles 2 and communicates with the first accommodation cavity 11, the through-hole 13 is used to discharge gas or liquid, thereby providing a toothbrush head that can discharge gas or liquid for cleaning, improving the cleaning effect of the toothbrush head on the teeth.
[0032] As Figure 3-6 shown, at least one partition 14 is provided in the first accommodation cavity 11. In the specific implementation process, the number of partitions 14 is set to be multiple, and the multiple partitions 14 are distributed along the axial direction of the first accommodation cavity 11; through the arrangement of the partitions 14, it is convenient to circulate gas or liquid. When circulating gas, the partitions 14 can enhance the generation quantity of bubbles, further improving the bubble effect of the toothbrush head and the tooth cleaning effect.
[0033] As Figure 3-6 shown, the partition 14 and the toothbrush handle 1 are of an integrally formed structure.
[0034] As Figure 1-4 shown, a sealing ring 3 is installed in the first accommodation cavity 11. It should be noted that the sealing ring 3 plays a sealing role, and when liquid circulates in the first accommodation cavity 11, it can prevent liquid leakage.
[0035] As Figure 1-4 shown, the sealing ring 3 abuts against the end of the partition 14.
[0036] As Figure 3 and Figure 6 shown, the through-hole 13 includes a first hole section 131, a second hole section 132, and a third hole section 133 that are sequentially and penetratingly arranged from the outside to the inside, and the third hole section 133 communicates with the first accommodation cavity 11.
[0037] As Figure 3 and Figure 6 shown, the cross-sections of the first hole section 131, the second hole section 132, and the third hole section 133 are all circular.
[0038] As Figure 3 and Figure 6 shown, the pore diameters of the first hole section 131, the second hole section 132, and the third hole section 133 show a decreasing trend. It should be noted that due to the decreasing trend of the pore diameters of the first hole section 131, the second hole section 132, and the third hole section 133, when liquid is discharged from the first accommodation cavity 11, it is convenient for the liquid to be ejected quickly
[0039] As Figure 1-7 shown, a connector 4 is installed in the second accommodation cavity 12, and the connector 4 is used for clamping with the drive shaft of the electric toothbrush. In the specific implementation process, the connector 4 and the toothbrush handle 1 are fixed by ultrasonic welding or bonding.
[0040] As Figure 3and Figure 7 As shown in Figure 7 , the connecting member 4 is provided with an elastic clamping arm 41. In this embodiment, a rib 42 is provided inside the connecting member 4. By providing the rib 42, the frictional force between the drive shaft and the connecting member 4 is increased.
[0041] It should be noted that by providing the clamping arm 41, it is convenient for the connecting member 4 to clamp the drive shaft, so that the drive shaft can drive the toothbrush head to vibrate or swing.
[0042] Working principle: Since the through-hole 13 is located between several tooth bristles 2 and communicates with the first accommodation cavity 11, the through-hole 13 is used to discharge gas or liquid, thereby providing a toothbrush head that can discharge gas or liquid for cleaning, improving the cleaning effect of the toothbrush head on the teeth.
[0043] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
