[0029] The embodiments of this utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figures 1-4 The oral irrigator 100 according to an embodiment of the present invention includes: a housing 10, a power element 20, and a seal 30.

[0030] Specifically, such as Figures 1-4 As shown, the power element 20 is disposed inside the housing 10; the seal 30 is disposed between the housing 10 and the power element 20, and the seal 30 is provided with at least one protrusion structure 31, which extends circumferentially along the housing 10 and contacts the housing 10.

[0031] The housing 10 extends circumferentially along the water flosser 100. Both the power element 20 and the seal 30 are located inside the housing 10. The seal 30 is positioned between the housing 10 and the power element 20 along the thickness direction of the housing 10. The seal 30 is adapted to prevent external moisture from entering the housing 10 through gaps in the housing 10. A protruding structure 31 is located between the side of the seal 30 away from the power element 20 along the thickness direction of the housing 10 and the inner wall of the housing 10. The side of the protruding structure 31 adjacent to the seal 30 along the thickness direction of the housing 10 is connected to the seal 30. The other side of the protruding structure 31 protrudes towards the housing 10 along the thickness direction of the housing 10, contacting and abutting against the inner wall of the housing 10.

[0032] According to the embodiment of the present invention, the water flosser 100, by placing the sealing element 30 between the housing 10 and the power element 20, and placing the protruding structure 31 on the side of the sealing element 30 away from the power element 20, increases the stress at the contact point between the sealing element 30 and the housing 10 at the protruding structure 31, and increases the abutment effect between the protruding structure 31 and the housing 10. This can effectively prevent moisture from the outside of the housing 10 from entering the inside of the housing 10 through the gaps in the housing 10, avoid water mist inside the housing 10, reduce the risk of damage to the power element 20 inside the housing 10 due to moisture, extend the service life of the water flosser 100, improve the sealing performance of the water flosser 100, and enhance the user experience.

[0033] According to some embodiments of this utility model, such as Figure 4 As shown, the cross-sectional area of ​​the protrusion 31 decreases along the side of the seal 30 adjacent to the power element 20 toward the side adjacent to the housing 10.

[0034] Along the thickness direction of the housing 10, from the side of the seal 30 away from the power element 20 towards the other side where the inner wall of the housing 10 is located, the cross-sectional area of ​​the protruding structure 31 gradually decreases. The protruding structure 31 is partially deformed by compression or partially embedded in the inner wall of the housing 10 to achieve a seal between the seal 30 and the housing 10.

[0035] Therefore, by designing the cross-sectional area of ​​the protruding structure 31 to decrease along the side of the seal 30 adjacent to the power element 20 towards the side adjacent to the housing 10, the protruding structure 31 can better abut against the housing 10, facilitate the deformation of the protruding structure 31, and increase the abutting effect of the protruding structure 31 against the housing 10 when it is squeezed during installation, so as to better prevent moisture from flowing from the seal 30 into the housing 10.

[0036] According to some embodiments of the present invention, the end face of the protruding structure 31 adjacent to the shell 10 is an arc surface with a radius of curvature R, where R satisfies: 0 < R ≤ 0.1 mm.

[0037] When the radius of curvature of the arc surface is greater than 0.1 mm, the radius of curvature of the arc surface is relatively large, which may make it difficult for the protruding structure 31 to contact the housing 10, resulting in a lower sealing performance between the seal 30 and the housing 10. For example, R = 0.1 mm.

[0038] Therefore, by limiting the range of the radius of curvature of the arc surface, it is easier for the protruding structure 31 and the housing 10 to contact, improve the sealing performance between the seal 30 and the housing 10, reduce the processing difficulty, facilitate the stop between the protruding structure 31 and the housing 10, improve the production efficiency of the water flosser 100, and improve the sealing performance and reliability of the water flosser 100.

[0039] Optionally, such as Figure 4 As shown, the end of the protruding structure 31 adjacent to the housing 10 is a sharp angle α, where α satisfies: 120° ≤ α < 180°. For example, the protruding structure 31 includes a first surface 311 and a second surface 312 disposed opposite each other along the circumference of the housing 10. The first surface 311 and the second surface 312 are located on the side of the protruding structure 31 that is away from each other along the axial direction of the housing 10. The first surface 311 and the second surface 312 are connected to each other and abut against the housing 10, respectively, adjacent to one end of the housing 10. The other end of the first surface 311 and the other end of the second surface 312 extend obliquely in the thickness direction of the housing 10 in a direction away from each other. The first surface 311 and the second surface 312 are planes, and the included angle between the first surface 311 and the second surface 312 is α.

[0040] When the angle of the sharp corner is less than 120°, the angle is too small, the structural strength of the seal 30 is low, which may reduce the contact area between the raised structure 31 and the housing 10, and reduce the connection strength and sealing performance between the raised structure 31 and the housing 10. For example, α=150°.

[0041] Therefore, by limiting the angle range of the sharp corner, the contact area between the protruding structure 31 and the housing 10 can be increased, the structural strength of the protruding structure 31 itself can be improved, the good stop between the protruding structure 31 and the housing 10 can be ensured, and the connection strength and sealing between the protruding structure 31 and the housing 10 can be improved, thereby improving the sealing and reliability of the oral irrigator 100.

[0042] According to some embodiments of this utility model, the protruding structure 31 and the sealing element 30 are integrally formed. The protruding structure 31 and the sealing element 30 can be manufactured as a whole. This improves the structural strength of the protruding structure 31 and the sealing element 30, reduces assembly steps, increases the production efficiency of the water flosser 100, and reduces production costs.

[0043] Optionally, the raised structure 31 and the seal 30 can be separably fitted. During manufacturing, the raised structure 31 and the seal 30 can be two independent components. This facilitates the maintenance and replacement of the raised structure 31 and the seal 30, increases the sealing performance at the raised structure 31, reduces the processing complexity of the water flosser 100, and helps to reduce costs.

[0044] According to some embodiments of this utility model, such as Figure 4 As shown, the height of the protruding structure 31 protruding from the surface of the seal 30 adjacent to the housing 10 along the thickness direction of the seal 30, i.e. the thickness direction of the housing 10, is H, and H satisfies: 0 < H ≤ 0.3 mm.

[0045] When the height of the protrusion 31 protruding from the surface of the seal 30 adjacent to the housing 10 along the thickness direction of the seal 30 is greater than 0.3 mm, the height of the protrusion 31 protruding from the surface of the seal 30 adjacent to the housing 10 along the thickness direction of the seal 30 is relatively large. This may lead to an increase in the gap between the seal 30 and the housing 10, reducing the sealing effect and increasing the space occupied inside the housing 10. For example, H=0.3 mm.

[0046] Therefore, by limiting the height range of the protrusion structure 31 protruding from the surface of the seal 30 adjacent to the housing 10 along the thickness direction of the seal 30, the sealing performance between the seal 30 and the housing 10 is ensured, while the internal space of the housing 10 is optimized, and production costs can be reduced.

[0047] Optionally, the protrusion 31 is at least partially embedded within the housing 10, and the width of the portion of the protrusion 31 embedded within the housing 10 along the axial direction of the housing 10 is 0.1 mm or 0.2 mm. This further ensures that moisture does not flow from the protrusion 31 between the seal 30 and the housing 10.

[0048] According to some embodiments of this utility model, the sealing element 30 is a light-transmitting element. This allows the light source inside the housing 10 to pass through the sealing element 30, reducing light source transmission losses and facilitating user observation of the working status of the oral irrigator 100 from outside the housing 10.

[0049] Optionally, the light transmittance of the seal 30 is T, where T satisfies: 70%≤T≤80%.

[0050] When the light transmittance of the seal 30 is less than 70%, the light transmittance of the seal 30 is low, making it difficult for the light source inside the housing 10 to pass through the seal 30; when the light transmittance of the seal 30 is greater than 80%, the light transmittance of the seal 30 is high, which can easily reduce the user's experience when observing the oral irrigator 100, and also affect the clarity. For example, T=75%.

[0051] Therefore, by limiting the range of light transmittance of the seal 30, the light source inside the housing 10 can pass through the seal 30, reducing the loss during the light transmission process, making it easier for the user to observe the working status of the water flosser 100, and improving the user experience.

[0052] Optionally, the seal 30 is made of soft rubber. This facilitates the absorption of energy generated by vibration during the operation of the water flosser 100, extends the service life of the water flosser 100, reduces noise, and allows the seal 30 to deform during assembly, which helps to increase the sealing performance at the protruding structure 31.

[0053] According to some embodiments of this utility model, such as Figure 3 As shown, there are multiple protrusions 31, and the multiple protrusions 31 are respectively arranged near the two ends of the seal 30 along the axial direction of the housing 10, that is, the height direction of the tumbler 100.

[0054] Multiple protrusions 31 extend circumferentially along the water flosser 100, are adapted to the shape of the inner wall of the housing 10, and are respectively located near the two ends of the seal 30 along the axial direction of the water flosser 100. The side of the multiple protrusions 31 away from the seal 30 along the thickness direction of the housing 10 respectively contacts the corresponding inner wall of the housing 10.

[0055] Therefore, by setting multiple protruding structures 31, the contact area between the protruding structure 31 and the housing 10 can be increased, thereby increasing the connection strength between the protruding structure 31 and the housing 10. At the same time, the sealing performance between the sealing element 30 and the housing 10 is improved, preventing moisture from the outside of the housing 10 from entering between the sealing element 30 and the housing 10 through the gap between the protruding structure 31 and the housing 10, thus improving the sealing performance of the oral irrigator 100 and extending the service life of the oral irrigator 100.

[0056] According to some embodiments of this utility model, such as Figure 3 As shown, at least a portion of the housing 10 is configured as a first light-transmitting portion 111. The power element 20 includes a control board 21, on which a light source is provided. The first light-transmitting portion 111 is disposed opposite to the light source. A sealing member 30 is disposed between the first light-transmitting portion 111 and the control board 21 to prevent water vapor from entering the area between the sealing member 30 and the housing 10 from the outside of the housing 10.

[0057] In this embodiment, the control plate 21 extends along the axial direction of the housing 10, and the light source is transmitted from the control plate 21 toward the corresponding housing 10. The first light-transmitting part 111 is opposite to the light source along the thickness direction of the housing 10. The light source on the control plate 21 can pass through the first light-transmitting part 111. The sealing member 30 has a protruding structure 31 on the side away from the control plate 21 along the thickness direction of the housing 10. The protruding structure 31 is in contact with the inner wall of the first light-transmitting part 111 on the side adjacent to the first light-transmitting part 111 along the thickness direction of the housing 10.

[0058] Therefore, by setting the first light-transmitting part 111 opposite to the light source, the light source can easily pass through the first light-transmitting part 111, making it easier for the user to observe the light source and thus observe the specific working status of the water flosser 100. At the same time, by placing the sealing element 30 between the first light-transmitting part 111 and the control board 21, moisture can be prevented from entering the space between the first light-transmitting part 111 and the corresponding sealing element 30 from the outside of the housing 10, thereby improving the sealing performance of the water flosser 100, avoiding the generation of water mist between the first light-transmitting part 111 and the corresponding sealing element 30, improving the clarity of the light source when viewed from the outside of the housing 10, and thus improving the user experience.

[0059] According to some embodiments of this utility model, such as Figure 3 As shown, there are multiple light sources. The sealing member 30 includes a main body 32 and multiple second light-transmitting parts 33. The multiple second light-transmitting parts 33 are spaced apart along the axial direction of the housing 10. The multiple second light-transmitting parts 33 protrude from at least one side surface of the main body 32 along the thickness direction. The multiple second light-transmitting parts 33 are respectively arranged opposite to the multiple light sources.

[0060] The main body 32 and the plurality of second light-transmitting portions 33 extend circumferentially along the water flosser 100. The plurality of second light-transmitting portions 33 are spaced apart along the height direction of the water flosser 100 on one side surface of the main body 32 adjacent to the housing 10 along the thickness direction. The side of each second light-transmitting portion 33 away from the housing 10 along the thickness direction is connected to the main body 32, and the other side of the second light-transmitting portion 33 protrudes towards the housing 10 along the thickness direction. Each second light-transmitting portion 33 can be opposite a corresponding light source along the thickness direction of the housing 10, facilitating the user's observation of the corresponding light source information. Each second light-transmitting portion 33 can be used to display different functional information.

[0061] Therefore, by providing multiple second light-transmitting portions 33, the light source can easily pass through the multiple second light-transmitting portions 33 and then through the first light-transmitting portion 111, reducing the loss during the light source transmission process and making it easier for the user to observe. At the same time, by having multiple second light-transmitting portions 33 protrude from at least one side surface of the body portion 32 along the thickness direction of the body portion 32, the transmission efficiency of the light source can be improved.

[0062] Optionally, the second light-transmitting part 33 is formed as a light guide post, which is opposite to the light source, so that the information displayed by the light source can be viewed more clearly from the outside of the housing 10, thereby increasing the clarity of the light source display and reducing the influence of ambient light on the clarity of the light source display.

[0063] According to some embodiments of this utility model, the area of ​​the main body 32 between two adjacent second light-transmitting parts 33 is a light-transmitting part. In this case, both the main body 32 and the protruding structure 31 are transparent, possessing the ability to transmit light. Therefore, both the main body 32 and the second light-transmitting part 33 are light-transmitting parts, having a light-transmitting function, which can increase the user's viewing angle range of the display light source, making it easier for the user to observe the working status of the oral irrigator 100 from multiple angles, thus improving the user experience.

[0064] Optionally, the area of ​​the main body 32 located between two adjacent second light-transmitting parts 33 is a light-shielding part.

[0065] Optionally, the second light-transmitting portion 33 is a light-transmitting portion, and the area of ​​the corresponding body portion 32 between adjacent second light-transmitting portions 33 is a light-shielding portion. In this case, the second light-transmitting portions 33 are respectively arranged opposite to the light source to transmit the light source, making it convenient for the user to view the content displayed by the light source from outside the housing 10. The area between adjacent second light-transmitting portions 33 is a light-shielding portion to prevent light from scattering on the body portion 32, reduce the impact of stray light on viewing, and make the display effect clearer.

[0066] According to some embodiments of this utility model, such as Figure 3 As shown, the oral irrigator 100 also includes: a mounting bracket 40, which is disposed between the power element 20 and the housing 10, and has an opening 41. A control plate 21 is connected to the mounting bracket 40 and is disposed opposite to the opening 41. A sealing member 30 is detachably connected to the mounting bracket 40 at the opening.

[0067] The mounting bracket 40 extends circumferentially along the water flosser 100, and at least a portion of the mounting bracket 40 is disposed between the power element 20 and the housing 10 along the thickness direction of the housing 10. The mounting bracket 40 has an opening 41, which is opposite to a first light-transmitting portion 111 disposed on the housing 10. The area of ​​the first light-transmitting portion 111 is greater than or equal to the area of ​​the opening 41. A sealing member 30 is disposed at the opening and is fixedly connected to the mounting bracket 40 at the opening. A portion of the control panel 21 with a light source is disposed opposite to the opening 41. The light emitted by the light source is emitted through the sealing member 30 and the first light-transmitting portion 111, allowing the user to view the corresponding display content outside the housing 10.

[0068] Therefore, by setting up the mounting bracket 40, the installation and fixing of the seal 30 can be facilitated, the positioning of the seal 30 can be facilitated, the assembly efficiency of the seal 30 can be improved, and thus the production efficiency of the water flosser 100 can be improved.

[0069] Optionally, the edge of the opening of the mounting bracket 40 is provided with a stepped portion, and the seal 30 is provided at the stepped portion. The step portion can block the air intake path of water vapor at the connection between the seal 30 and the mounting bracket 40, increase the sealing effect, prevent water vapor from entering the internal control board 21 and causing the control board 21 to short circuit, and improve the safety and reliability of the water flosser 100.

[0070] According to some embodiments of this utility model, such as Figure 3 As shown, the housing 10 includes: a first housing portion 11 and a second housing portion 12. The first housing portion 11 has a first light-transmitting portion 111. The first housing portion 11 and the second housing portion 12 are separably fitted together. The connection between the first housing portion 11 and the second housing portion 12 is disposed opposite to the mounting bracket 40. The protruding structure 31 contacts one end of the first housing portion 11 adjacent to the second housing portion 12. The first light-transmitting portion 111 is located at the other end of the first housing portion 11 away from the second housing portion 12.

[0071] The first housing portion 11 and the second housing portion 12 both extend circumferentially along the water flosser 100. The first housing portion 11 and the second housing portion 12 are detachably connected along the height direction of the water flosser 100. The connection between the first housing portion 11 and the second housing portion 12 is opposite to the mounting bracket 40 along the thickness direction of the housing 10. The first housing portion 11 has a first light-transmitting portion 111. The protruding structure 31 on the sealing member 30 is located at one end of the first housing portion 11 adjacent to the second housing portion 12 along the height direction of the water flosser 100. The protruding structure 31 is located above the first light-transmitting portion 111 along the height direction of the water flosser 100 and below the connection between the first housing portion 11 and the second housing portion 12.

[0072] Therefore, the first housing part 11 and the second housing part 12 can be detachably fitted, which facilitates the maintenance and replacement of the first housing part 11 and the second housing part 12, reduces the processing complexity of the water flosser 100, and helps to reduce costs. At the same time, the connection between the first housing part 11 and the second housing part 12 is positioned opposite to the mounting bracket 40, which facilitates the positioning of the mounting bracket 40 and improves the assembly efficiency of the water flosser 100. The protruding structure 31 can prevent water vapor entering from the connection between the first housing part 11 and the second housing part 12 from entering the area between the seal 30 and the housing 10 through the protruding structure 31, which can effectively prevent water mist from forming between the first light-transmitting part 111 and the corresponding seal 30, improve the sealing and reliability of the water flosser 100, reduce the impact of water mist on the clarity of the light source display, and enhance the user experience.
