[0025] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0026] Please see below. Figure 1 and Figure 2 The present invention provides a button assembly, which specifically includes:

[0027] The outer casing 10 has a first switch button 11, a second switch button 12 and a raised abutment part 13 on its surface, and the abutment part 13 is disposed between the first switch button 11 and the second switch button 12.

[0028] An integrated button cover 20 covers the first switch button 11 and the second switch button 12. The upper and lower ends of the integrated button cover 20 correspond to the first switch button 11 and the second switch button 12, respectively. The inner surface of the middle part of the integrated button cover 20 abuts against the supporting part 13.

[0029] In this embodiment, by providing a protruding abutting part 13 between the first switch button 11 and the second switch button 12, the integrated button cover 20 is held by the abutting part 13 when pressed, forming a lever structure. This allows the integrated button cover 20 to be pressed in only one direction, either the first switch button 11 or the second switch button 12, at the same time, preventing the simultaneous triggering of both upper and lower switch buttons. This effectively avoids misoperation, improves the stability and accuracy of button use, and thus enhances the user experience.

[0030] In one embodiment, the surface of the housing 10 is provided with a button groove, which cooperates with the outer edge of the integrated button cover 20 to enhance the positioning stability of the integrated button cover 20, ensuring that it is not easily shifted during use, thereby improving the accuracy and reliability of button operation and optimizing the user experience.

[0031] In one embodiment, the supporting part 13 is located at the symmetrical axis position in the key slot, which can ensure that the supporting part 13 provides balanced support to the integrated key cover 20, optimize the leverage effect, make the key operation smoother, reduce wear, extend service life, and improve the overall user experience.

[0032] In one embodiment, a spring-loaded structure is provided below the first switch button 11 and the second switch button 12. By providing the spring-loaded structure, it can be ensured that the one-piece button cover 20 returns to its original position after being pressed, so that the user can perform the next button operation.

[0033] In one embodiment, the supporting portion 13 is a raised beaded point that supports the inner surface of the central part of the integrated button cover 20, thereby forming a lever structure to prevent the simultaneous triggering of the upper and lower switch buttons. In other embodiments, the supporting portion 13 can also be a raised structure of other shapes to adapt to different operating habits and design requirements. For example, the supporting portion 13 can also be a long strip-shaped raised structure arranged along the horizontal axis of the button groove to provide more balanced support force and ensure that the integrated button cover 20 is stable and reliable when pressed.

[0034] In practical applications, the number and arrangement of the bead points can be adjusted according to actual needs. For example, only one bead point can be set at the intersection of the horizontal and vertical central axes of the button slot, thus reducing unnecessary complexity while ensuring functionality. Alternatively, multiple (two or more) bead points can be symmetrically distributed along the horizontal or vertical central axes of the button slot, thus forming a more stable support, further optimizing the leverage effect, and improving the stability and accuracy of button operation.

[0035] Understandably, when there is only one ball bearing, it needs to be positioned at the intersection of the horizontal and vertical central axes of the button slot to achieve balanced support for the integrated button cover 20. When there are two or more ball bearings, they only need to be evenly distributed along the horizontal or vertical central axes of the button slot. This ensures that each ball bearing effectively supports the integrated button cover 20, forming a balanced lever structure and further improving operational stability and accuracy. It is important to note that regardless of the number of ball bearings, they must all be located between the first switch button 11 and the second switch button 12.

[0036] In one embodiment, an elastic buffer layer is provided at the contact point between the inner surface of the integrated button cover 20 and the abutting part 13, so as to provide a certain buffer when the integrated button cover 20 is pressed, reduce the wear of the ball points, extend the service life, and enhance the sensitivity of the button rebound, ensuring timely feedback for each operation, and further improving the user's operating experience.

[0037] In one embodiment, the upper and lower areas of the integrated button cover 20 are treated with contrasting colors or materials, allowing users to intuitively distinguish button functions, enhancing visual recognition, and improving operational convenience. Furthermore, in specific application scenarios, different patterns can also be drawn directly on the upper and lower areas of the integrated button cover 20 for differentiation.

[0038] This utility model also provides a dental flosser, including the button assembly described above.

[0039] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably.
