Abstract
Description
Technical Field
[0001] This utility model relates to the field of oral care technology, specifically to a multifunctional oral cleaning device. Background Technology
[0002] Oral hygiene is an important part of daily cleaning. It mainly involves cleaning teeth, gums, and other components in the mouth to remove food debris, plaque, and other substances, thereby maintaining oral health and preventing dental diseases such as tooth decay and periodontal disease.
[0003] Oral hygiene typically involves using a toothbrush to remove food debris remaining in the mouth. Traditional toothbrushes have a one-piece design with the brush head and handle, making it impossible to adjust the angle of the brush head. This makes it difficult for existing toothbrushes to clean certain areas of the mouth, resulting in poor oral hygiene. Utility Model Content

The storage box can prevent dental floss and other oral cleaning items from entering, thus enriching the functionality of the device.
[0011] As an improvement: one side of the brush head has several protrusions, which can clean the tongue coating and improve the oral cavity cleaning effect, while also massaging the tongue. The handle has silicone layers on all four sides, which makes the user's grip more comfortable and provides greater friction.
[0012] (III) Beneficial Effects
[0013] The advantages of this utility model compared with the prior art are as follows:
[0014] 1. By adjusting the angle of the component, rotating the knob causes the connector to rotate the brush head, changing the brush head angle, making it easier to clean hard-to-reach areas such as behind teeth, between teeth, and near the gum line, thus improving the cleaning effect.
[0015] 2. The brush head can rotate to change its horizontal or vertical position. With the angle adjustment component, users can adjust it according to their own oral cavity structure and brushing habits to reduce pressure on the gums, improve user comfort, and enhance the practicality of the device.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.
[0026] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.
[0027] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0028] Combined with appendix Figure 1 and Figure 3 As shown, a multifunctional oral cleaning device includes a brush head 1 and a handle 2. The brush head 1 has several protrusions 22 on one side. The dots of the protrusions 22 can clean the tongue coating, improve the oral cavity cleaning effect, and massage the tongue. The handle 2 has silicone layers 23 on all four sides. The silicone layers 23 make the user's grip more comfortable and provide greater friction. One end of the handle 2 is provided with a fixing frame 3. A connecting seat 4 is rotatably provided on the fixing frame 3. The brush head 1 is threadedly connected to the connecting seat 4. The brush head 1 is detachable, allowing for the replacement of different types of brush heads 1. After a certain period of use, the brush head 1 can be replaced individually to reduce waste.
[0029] Combined with appendix Figures 4 to 7As shown, a protective shell 5 is provided on one side of the handle 2. An angle adjustment component for driving the connecting seat 4 to rotate is provided inside the protective shell 5. The angle adjustment component includes a first synchronous wheel 6, which is rotatably disposed between the protective shell 5 and the handle 2. The rotating shaft of the connecting seat 4 extends through the fixing frame 3 into the protective shell 5 and is connected to a second synchronous wheel 7. The first synchronous wheel 6 and the second synchronous wheel 7 are connected by a synchronous belt 8. The rotating shaft of the first synchronous wheel 6 extends through the protective shell 5 and is connected to a knob 9. Several slots 10 are arranged in a circular array on the inner wall of the knob 9. A housing 11 is provided on the outer wall of the protective shell 5. A locking rod 13 that cooperates with the slots 10 is connected inside the housing 11 by a telescopic spring 12.
[0030] When using the toothbrush, the brush head 1 enters the oral cavity. For corners such as behind the teeth, turn the knob 9. At this time, the knob 9 drives the synchronous pulley 6 to rotate, which in turn drives the synchronous pulley 7 to rotate through the synchronous belt 8. This causes the connecting seat 4 to rotate, which in turn causes the brush head 1 to change its angle. The locking lever 13 can be locked into the corresponding slot 10 under the action of the telescopic spring 12, fixing the angle of the brush head 1. This makes it easier for the brush head 1 to clean the hard-to-reach areas deep in the oral cavity, resulting in a more thorough cleaning and reducing the accumulation of plaque and food debris.
[0031] In combination with the above, and the appendix Figure 2 and Figure 3 As shown, the brush head 1 is rotatably provided with a bristle plate 14, and four clips 15 are arranged around the brush head 1. The contact surface between the bristle plate 14 and the brush head 1 is symmetrically provided with a fixing groove 16 that cooperates with the clips 15. The brush head 1 is generally used in a vertical state. Some users may be accustomed to brushing vertically, so the bristle plate 14 can be rotated to a horizontal state. At this time, the clips 15 are locked in the fixing groove 16 to fix the position of the bristle plate 14 and maintain the stability during use.
[0032] Combined with appendix Figure 4 and Figure 8 As shown, the handle 2 has a connecting groove 17 on the side opposite to the connecting seat 4. A storage box 18 is snapped into the connecting groove 17. A locking block 19 is symmetrically arranged on the outer wall of the storage box 18. A limiting plate 20 is provided in the connecting groove 17, and the limiting plate 20 has a notch 21 that cooperates with the locking block 19. The locking block 19 enters into the connecting groove 17 through the notch 21. By offsetting their positions, the storage box 18 is snapped into the connecting groove 17. The storage box 18 can store dental floss and other oral cleaning items for use during oral cleaning.
[0033] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
