[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is 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 invention and are not intended to limit the present invention.

[0028] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or indirect connections through an intermediate medium; they may refer to internal connections between two components; they may refer to wireless connections or wired connections. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0029] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] According to the first aspect, the embodiment of the present utility model discloses a key structure, such as Figure 1-7 As shown, it includes: a body soft rubber 10 for being nested in the water flosser body 30, with at least one button 20 installed on the body soft rubber 10; a boss 11 is provided on the body soft rubber 10, and a surrounding bone 21 that can wrap the boss 11 is provided on the button 20.

[0032] It should be noted that the body soft rubber 10 is formed in the body 30 by secondary injection molding. Wrapping refers to the inner side wall of the surrounding bone 21 on the button being in contact with the outer side wall of the boss 11. By providing the boss 11 on the body soft rubber 10 and the surrounding bone 21 on the button 20, a button structure and a water flosser are provided. Since the surrounding bone 21 can wrap the boss 11, the button 20 can be positioned and installed to prevent misalignment during installation.

[0033] like Figure 1-6 As shown, the cross-section of the boss 11 is a non-rotationally symmetrical figure. It should be noted that, since the rib 21 wraps around the boss 11, the shape formed by the rib 21 is a non-rotationally symmetrical figure that is consistent with the cross-section of the boss 11. The front of the button 20 is marked with a pattern, and the rib 21 is located on the back of the button 20. During the assembly process of the button 20, the angle of the pattern corresponding to the button 20 is fixed, as shown in FIG. Figure 7 For a key with three line segments, the three line segments must be arranged vertically, not horizontally, with the shorter line segment located on the left. Therefore, accurate angular positioning of key 20 is required. Because the cross-sectional shape of boss 11 is a rotationally asymmetric pattern, key 20 can only be installed on boss 11 according to the corresponding installation orientation. This allows for unique angular positioning of key 20, providing a foolproof installation method. A rotationally asymmetric pattern is a pattern other than a rotationally symmetric pattern, meaning that the non-rotationally asymmetric pattern does not overlap with the initial pattern at any angle during a 360-degree rotation about its center point.

[0034] Furthermore, at least one mounting surface 111 is provided on the outer wall of the boss 11, and a fitting surface 211 is provided on the inner wall of the frame 21 to fit with the mounting surface 111. Since at least one mounting surface 111 is provided, the mounting surface 111 and the fitting surface 211 fit together, which facilitates the processing and demolding of the body soft plastic 10 and the assembly of the button 20.

[0035] like Figure 1-6 As shown, the number of the mounting planes 111 is set to two. It should be noted that, since the number of the mounting planes 111 is set to two, it further prevents the button 20 from being offset when being installed, and further prevents the button 20 from rotating after being installed.

[0036] like Figure 1-3 As shown, the two mounting planes 111 are parallel to each other, or the two mounting planes 111 are arranged at an angle.

[0037] like Figure 1-6As shown, there are at least two buttons 20, and the cross-sectional shapes of the bosses 11 corresponding to at least two buttons 20 are different. In a specific implementation, the front patterns of at least two buttons 20 are different, and the installation positions of the buttons with different patterns must be unique and fixed. For example, button 1 should be installed on boss 1, and button 2 should be installed on boss 2. Due to the different cross-sectional shapes, button 1 cannot be mistakenly installed on boss 2 and can only be installed on boss 1. This prevents misinstallation of buttons 20 and ensures the unique installation position of buttons 20.

[0038] like Figure 1-3 As shown, the table 112 of the boss 11 is flat, and the contact surface between the key 20 and the table 112 is also flat. It should be noted that since the table 112 of the boss 11 is flat, during installation, the table 112 of the boss 11 is in contact with the key 20, and the height direction of the key 20 is positioned by the large flat surface. This can ensure the height and flatness of the key 20, make the key 20 install smoothly, prevent it from tilting, and facilitate the positioning and installation of the key 20 in terms of height and flatness.

[0039] like Figure 1-6 As shown, a glue dispensing groove 113 is provided on the table surface 112 of the boss 11. In the specific implementation process, the glue dispensing groove 113 is arranged in a ring shape, and glue is dripped into the glue dispensing groove 113 to bond the button 20 to the body soft glue 10. Through the provision of the glue dispensing groove 113, the button 20 can be bonded and installed with less glue.

[0040] like Figure 6 As shown, the boss 11 is provided with a groove 114. It should be noted that, since the boss 11 is provided with the groove 114, it can avoid shrinkage during molding due to the boss 11 being too thick.

[0041] like Figure 2-6 As shown, the button 20 is provided with a pressing post 22 that is inserted into the groove 114, with a gap between the pressing post 22 and the inner wall of the groove 114. In a specific implementation, a pressing portion 12 corresponding to the pressing post 22 is provided on the back of the body soft plastic 10. The user presses the button 20 with a finger, causing the pressing portion 12 to press the electronic device on the control panel, thereby realizing the pressing operation of the button 20 and correspondingly controlling the working state of the water flosser.

[0042] It should be noted that since there is a gap between the pressing column 22 and the inner wall of the groove 114, there is a gap between the pressing column 22 and the groove wall and the groove bottom, thereby reserving a space to avoid the air, and the user can feel a sense of frustration when using the button 20, which improves the user experience.

[0043] like Figure 1-6As shown, the number of buttons 20 is set to three. In the specific implementation process, the first button 20 is a switch key for controlling the opening and closing of the water flosser, the second button 20 is a gear key for adjusting the operating gear of the water flosser, and the third button 20 is a mode key for selecting the working mode of the water flosser.

[0044] According to the second aspect, the embodiment of the present utility model discloses a water flosser, such as Figure 7 As shown, the key structure of the first aspect is provided. By providing a boss 11 on the body soft rubber 10 and a rib 21 on the key 20, a key structure and a water flosser are provided. Since the rib 21 can wrap around the boss 11, the key 20 can be positioned and installed. Since the installation plane 111 and the fitting plane 211 fit together, the key 20 can be prevented from being misaligned during installation, ensuring normal use of the key 20.

[0045] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
