[0029] The embodiments of this utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figures 1-5 The oral irrigator 100 according to an embodiment of the present utility model includes: a housing 10 and a button support 20.

[0030] Specifically, such as Figure 1 and Figure 5 As shown, the housing 10 has a mounting hole 11; the button support 20 has a mounting groove 21, which extends along the outer periphery of the button support 20, and the mounting groove 21 is separably engaged with the edge of the mounting hole 11.

[0031] The housing 10 extends circumferentially along the water flosser 100, and the housing 10 extends along... Figure 1 A mounting hole 11 is formed on one side wall of the housing 10 along the first direction A. The mounting hole 11 penetrates the housing 10 along the first direction A, and the button support 20 is disposed at the mounting hole 11. In this embodiment, the mounting groove 21 surrounds the outer periphery of the button support 20 around the first direction A. Figure 1 The mounting grooves 21 formed on both sides of the second direction B open outwards in the direction away from each other along the second direction B, and the mounting grooves 21 respectively form a separable fit with the edge of the corresponding mounting hole 11.

[0032] According to the embodiment of the present utility model, the mounting groove 21 on the button support 20 can be separably fitted with the edge of the mounting hole 11, which facilitates the sealing of the mounting support and the edge of the mounting hole 11, improves the sealing performance of the water flosser 100, prevents external dust and other impurities from entering the interior of the housing 10 through the gap between the button support 20 and the edge of the mounting hole 11, avoids damage to the internal structural components of the housing 10, extends the service life of the water flosser 100, and improves the reliability of the water flosser 100.

[0033] According to some embodiments of this utility model, such as Figures 2-4 As shown, the button support 20 includes: a first connecting part 22 and a second connecting part 23. The first connecting part 22 is located on one side of the housing 10 along the thickness direction, i.e., the first direction A; the second connecting part 23 is located on the other side of the housing 10 along the thickness direction. The first connecting part 22 and the second connecting part 23 define a mounting groove 21.

[0034] In this embodiment, the button support 20 includes two first connecting portions 22 and two second connecting portions 23. The two first connecting portions 22 and the two second connecting portions 23 are both disposed on both sides of the button support 20 along the circumference of the button support 20. The two first connecting portions 22 are disposed on the side of the housing 10 away from the center of the housing 10 along the first direction A, and the two second connecting portions 23 are disposed on the other side of the housing 10 adjacent to the center of the housing 10 along the first direction A. A mounting groove 21 is defined between the first connecting portions 22 and the second connecting portions 23.

[0035] Therefore, by setting the first connecting part 22 and the second connecting part 23, the button support 20 covers the edge of the mounting hole 11 in the first direction A. The button support 20 is assembled with the housing 10 through the cooperation of the mounting groove 21 with the edge of the mounting hole 11, thereby fixing and limiting the button support 20. At the same time, the first connecting part 22 and the second connecting part 23 define the mounting groove 21. After the mounting groove 21 and the mounting hole 11 are engaged, the air intake path inside and outside the housing 10 is closed, which can achieve secondary sealing of the water flosser 100 and further improve the sealing performance and reliability of the water flosser 100.

[0036] Optionally, the button support 20 further includes a connecting body 27, with the first connecting part 22 and the second connecting part 23 respectively disposed on the outer periphery of the connecting body 27 and located on both sides of the connecting body 27 along the first direction A. The first connecting part 22, the second connecting part 23 and the connecting body 27 together define the mounting groove 21.

[0037] According to some embodiments of the present invention, the area of ​​the projection of the first connecting part 22 along the thickness direction of the button support 20, i.e., the first direction A, at least partially overlaps with the area of ​​the projection of the edge of the mounting hole 11 along the thickness direction of the button support 20. The width of the overlapping area along the circumference of the housing 10 is L1, and L1 satisfies: 0 < L1 ≤ 5 mm.

[0038] That is, after the button support 20 is assembled with the mounting hole 11, at least a portion of the first connecting part 22 coincides with at least a portion of the edge of the adjacent mounting hole 11 along the first direction A. When the width of the overlapping area along the circumference of the housing 10 is greater than 5mm, the width of the overlapping area along the circumference of the housing 10 is too large, which may increase the cost of the first connecting part 22 and make installation more difficult. For example, L1 = 3mm.

[0039] Therefore, by limiting the width range of the overlapping area along the circumference of the housing 10, the contact area between the first connecting part 22 and the housing 10 can be increased, ensuring that the first connecting part 22 is in full contact with the edge of the mounting hole 11, improving the sealing performance of the first connecting part 22, ensuring smooth installation, and effectively reducing costs.

[0040] Optionally, the area of ​​the second connecting portion 23 projected along the thickness direction of the button support member 20, i.e., the first direction A, at least partially overlaps with the area of ​​the edge of the mounting hole 11 projected along the thickness direction of the button support member 20. The width of the overlapping area along the circumferential direction of the housing 10 is L2, and L2 satisfies: 0 < L2 ≤ 5 mm.

[0041] When the width of the overlapping area along the circumference of the housing 10 is greater than 5 mm, the width of the overlapping area along the circumference of the housing 10 is too large, which may increase the cost of the second connection part 23. For example, L2 = 2 mm.

[0042] Therefore, by limiting the width range of the overlapping area along the circumference of the housing 10, it can be ensured that the second connection part 23 is in full contact with the edge of the mounting hole 11, thereby improving the sealing performance of the second connection part 23 and reducing costs.

[0043] Optionally, L1 satisfies: 0 < L1 ≤ 5 mm, and L2 satisfies: 0 < L2 ≤ 5 mm. This further improves the sealing performance of the button support 20 and enhances the connection strength between the button support 20 and the edge of the mounting hole 11.

[0044] According to some embodiments of this utility model, such as Figure 3 and Figure 5 As shown, the first connecting part 22 is located on the outside of the housing 10, and the second connecting part 23 is located on the inside of the housing 10. The thickness of the first connecting part 22 is greater than or equal to the thickness of the second connecting part 23.

[0045] In this embodiment, the first connecting part 22 is disposed along the first direction A on the side of the housing 10 away from the center of the housing 10, i.e., the outer side, and the second connecting part 23 is disposed along the first direction A on the side of the housing 10 adjacent to the center of the housing 10, i.e., the inner side, and the thickness of the first connecting part 22 along the first direction A is greater than or equal to the thickness of the second connecting part 23 along the first direction A.

[0046] Therefore, by having the first connecting part 22 and the second connecting part 23 respectively provided on the outer and inner sides of the housing 10, the outer and inner sides of the housing 10 can be sealed respectively. At the same time, since the thickness of the first connecting part 22 is greater than or equal to the thickness of the second connecting part 23, the structural strength of the first connecting part 22 can be improved to facilitate pressing, while also increasing the sealing effect.

[0047] According to some embodiments of this utility model, the button support 20 and the housing 10 are integrally formed. That is, the button support 20 and the housing 10 can be manufactured as a whole. This improves the structural strength of the button support 20 and the housing 10, increases the production efficiency of the water flosser 100, and reduces production costs.

[0048] Optionally, the button support 20 and the housing 10 can be manufactured separately. During the manufacturing process, the button support 20 and the housing 10 can be two independent components. This facilitates the maintenance and replacement of the button support 20 and the housing 10, reduces the processing complexity of the water flosser 100, and helps to reduce costs.

[0049] According to some embodiments of this utility model, the depth of the mounting groove 21 along the circumferential direction of the housing 10 is H, where H satisfies: 0 < H ≤ 5 mm.

[0050] When the depth of the mounting groove 21 along the circumference of the housing 10 is greater than 5mm, the depth of the mounting groove 21 along the circumference of the housing 10 is too large, which may reduce the structural strength of the button support 20 and increase the difficulty of installing the button support 20 and the housing 10. For example, H=3mm.

[0051] Therefore, by limiting the depth range of the mounting groove 21 along the circumferential direction of the housing 10, it can be ensured that the button support 20 and the edge of the mounting hole 11 are in full contact, so as to achieve precise assembly of the button support 20 and the mounting hole 11. At the same time, the structural strength of the button support 20 is improved and the service life of the button support 20 is extended.

[0052] Optionally, when the bottom surface of the mounting groove 21 of the button support 20 mates with the edge of the mounting hole 11, a gap is formed, which is beneficial to the absorption of deformation of the button support 20 when it is pressed.

[0053] According to some embodiments of this utility model, such as Figure 3As shown, the side wall of the mounting hole 11 is provided with a stepped portion 12. The stepped portion 12 is located on one side edge of the mounting hole 11 near the center of the housing 10. The stepped portion 12 extends circumferentially along the mounting hole 11 and mates with the mounting groove 21.

[0054] In this embodiment, the mounting hole 11 has stepped portions 12 formed on both sides of the second direction B, and the stepped portions 12 are disposed near the center of the housing 10 along the first direction A. The stepped portions 12 extend in a direction perpendicular to the first direction A toward each other. The button support member 20 is disposed in the area enclosed by the stepped portions 12, and at least part of the stepped portions 12 and the button support member 20 abut against each other. The stepped portions 12 are partially located in the mounting groove 21, and the stepped portions 12 are adapted to form a separable fit with the mounting groove 21.

[0055] Therefore, by providing a stepped portion 12 on the side wall of the mounting hole 11, it is convenient to assemble the mounting groove 21 of the button support 20 with the housing 10, thereby improving assembly efficiency. At the same time, it provides a limiting function for the button support 20, preventing the button support 20 from falling off, and improving the connection strength and reliability between the button support 20 and the housing 10.

[0056] The step portion 12 includes a first contact surface and a second contact surface. The first contact surface is disposed opposite to and in contact with the outer peripheral surface of the first connecting portion 22 along a direction perpendicular to the first direction A. The second contact surface is disposed on the side of the first contact surface adjacent to the center of the housing 10 along the first direction A. The second contact surface is disposed opposite to the side surface of the mounting groove 21 away from the center of the housing 10 along the first direction A. The first contact surface and the second contact surface are connected to each other.

[0057] According to some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, a relief groove 24 is formed on the side of the button support member 20 away from the center of the housing 10, and at least one protrusion 25 is provided in the relief groove 24; the water flosser 100 also includes a function key 30, which cooperates with the protrusion 25.

[0058] The button support 20 has a relief groove 24 formed on the side away from the center of the housing 10 along the first direction A, and the relief groove 24 is open in the direction away from the center of the housing 10 along the first direction A. The protrusion 25 is connected to the bottom of the relief groove 24 at one end along the first direction A near the center of the housing 10, and the other end extends in the direction away from the center of the housing 10 along the first direction A. The function key 30 is provided on the side of the button support 20 away from the center of the housing 10 along the first direction A. The function key 30 is adapted to form a detachable engagement with the protrusion 25 along the first direction A. The shape and size of the function key 30 are adapted to the button support 20.

[0059] In this embodiment, the clearance groove 24 is provided with a plurality of protrusions 25, which are spaced apart along a third direction C. The third direction C is orthogonal to the first direction A and the second direction B.

[0060] Therefore, by providing at least one protrusion 25 in the relief groove 24, the function key 30 can be easily assembled through the protrusion 25, which effectively improves the installation efficiency of the water flosser 100. By setting the function key 30, the sealing performance of the water flosser 100 can be further improved. At the same time, by pressing the function key 30, the user can switch between different working modes of the water flosser 100, which is convenient to operate and improves the user experience.

[0061] Optionally, the function key 30 is located on the side of the case support member away from the center of the housing 10, and the function key 30 abuts against the case support member. The edge of the first connecting portion 22 adjacent to the relief groove 24 is spaced apart from the function key 30, which increases the deformation range of the function key 30 in the first direction A, making it easier to press the function key 30 while also helping the function key 30 to rebound and increasing the tactile feel of pressing.

[0062] According to some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, a positioning groove 26 is formed on the side of the protrusion 25 away from the center of the housing 10, and a positioning post 31 is provided on the side of the function key 30 facing the button support 20. The positioning post 31 and the positioning groove 26 can be separably engaged.

[0063] The protrusion 25 defines the positioning groove 26. The function key 30 is provided with a positioning post 31 on the side facing the center of the housing 10 along the first direction A. One end of the positioning post 31 is connected to the function key 30, and the other end of the positioning post 31 extends along the first direction A towards the center of the housing 10. The positioning post 31 and the positioning groove 26 form a separable fit along the first direction A.

[0064] Optionally, the function key 30 is provided with a plurality of positioning posts 31 on the side facing the button support 20. The plurality of positioning posts 31 are spaced apart along a third direction C, and the plurality of positioning posts 31 respectively form a separable engagement with two adjacent protrusions 25 along a first direction A.

[0065] Therefore, by setting the positioning post 31 and the positioning groove 26, the installation process of the function key 30 can be optimized, thereby improving the assembly efficiency of the function key 30 and the button support 20 and reducing costs.

[0066] According to some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the oral irrigator 100 also includes a power element 40, which is disposed inside the housing 10. The power element 40 includes a control board 41, which is in contact with the button support 20.

[0067] The control board 41 is disposed inside the housing 10 along the first direction A and adjacent to the inner wall of the housing 10. The control board 41 is provided with a plurality of power devices along the side of the button support member 20 along the first direction A. At least some of the power devices are in contact with the button support member 20. When the user presses the function key 30 in the direction of the first direction A toward the center of the housing 10, the pressure is transmitted to the control board 41 along the first direction A. The control board 41 receives the signal and feeds it back to other components of the power element 40, thereby realizing the switching of the function of the water flosser 100.

[0068] Therefore, by setting a power element 40 inside the housing 10 of the water flosser 100, and by having the control board 41 in contact with the button support 20, the control board 41 can quickly transmit signals to quickly switch the working mode of the water flosser 100, thereby improving the working efficiency of the water flosser 100 and enhancing the user experience.
