Abstract
Description
Technical Field
[0001] This invention relates to the field of oral hygiene technology, and in particular to a nozzle and a water flosser equipped with the nozzle. Background Technology
[0002] Water flossers, as oral care devices, are widely used in people's daily lives because they use pressure to spray a stream of water from a nozzle to clean the mouth. Currently, there are various types of water flosser nozzles on the market to meet different usage needs and produce different water output effects.
[0003] However, to switch between different water flow effects, users must replace the corresponding nozzles, a process that is not only cumbersome but also requires carrying multiple nozzles. Furthermore, when not in use, various types of nozzles are easily lost and inconvenient to store, often requiring users to repurchase them when needed. This not only increases costs but also significantly impacts the user experience. Utility Model Content
[0004] The purpose of this application is to provide a nozzle and a water flosser equipped with the nozzle, which aims to solve the problem that the existing technology cannot achieve the switching of different water jet patterns on the same nozzle, thereby improving the user experience.
[0005] To achieve the above objectives, this application provides a nozzle, including a body and an adjustment component. The adjustment component includes a core and a cover. The adjustment component is disposed at the outlet of the body. The core has a liquid channel for liquid flow inside. The liquid channel includes a fixed section and an outlet section connected sequentially along the liquid flow direction. The fixed section is disposed on the outlet of the body. The cover is placed on the core, and one end of the cover is connected to the outlet end of the outlet section. The inner wall of the other end of the cover is provided with a second limiting part. The end of the body near the fixed section is provided with a plurality of first limiting parts along the water flow direction. Alternatively, the inner wall of the other end of the cover is provided with a plurality of second limiting parts along the water flow direction, and the end of the body near the fixed section is provided with a first limiting part.
[0006] By adjusting the cooperation between the first limiting part and the second limiting part, the water outlet section is deformed to adjust the ejection shape of the clean water flow.
[0007] Optionally, the water outlet section includes a deformation section and a diffusion section. The deformation section is located between the fixed section and the diffusion section, and the channel diameter of the deformation section is flat. The channel diameter of the diffusion section gradually increases along the flow direction, and the cover is connected to the water outlet end of the diffusion section.
[0008] Optionally, the inner cavity of the deformation section is cylindrical, and the inner cavity of the diffusion section is a frustum extending from one end near the deformation section to the other end.
[0009] Optionally, when the cooperation between the first limiting part and the second limiting part causes the other end of the cover to be relatively close to the water outlet, the inner cavity of the deformable section is cylindrical, thereby causing the clean water to be ejected in a columnar shape when it flows through the core.
[0010] When the first limiting part and the second limiting part cooperate to make the other end of the cover relatively far away from the water outlet, the inner cavity of the deformation section is squeezed towards the water outlet of the body, so as to form a frustum shape extending from the water outlet of the body to the water outlet end of the diffusion section together with the inner cavity of the diffusion section, thereby making the clean water flow out in a scattering form when it flows through the core.
[0011] Optionally, the end of the main body near the fixed section is recessed inward to form a positioning groove, and the end of the fixed section is provided with a snap-fit part, which is disposed in the positioning groove so that the fixed section is attached to the outlet of the main body.
[0012] Optionally, the snap-fit portion is an annular protrusion, and the positioning groove is an annular recess, wherein the width of the positioning groove is less than or equal to the width of the snap-fit portion.
[0013] Optionally, the first limiting part is a hemispherical protrusion, and the second limiting part is two consecutive hemispherical grooves.
[0014] Optionally, the first limiting part is an annular protrusion, and the second limiting part is two consecutive annular grooves, wherein the groove width of the second limiting part is less than or equal to the width of the first limiting part.
[0015] Optionally, the core and the cover are an integral structure, or they are separate structures.
[0016] This application also provides a water flosser, including a water flosser body and a nozzle as described above, wherein the output end of the water flosser body is connected to the water inlet end of the body.
[0017] This application sets the adjustment component on the water outlet end of the main body and adjusts the cooperation relationship between the first limiting part and the second limiting part to cause the water outlet section of the core to deform, thereby realizing that the clean water flow is ejected in different forms. In this way, users no longer need to prepare multiple nozzles, reducing costs and improving the user experience. Attached Figure Description

[0031] Figure 1 This is a schematic diagram of the front view structure of a body 1 according to an embodiment of this application. Figure 2 This is a front view schematic diagram of an adjustment component 2 according to an embodiment of this application, as shown below. Figure 1 and Figure 2 As shown, in one embodiment, the nozzle includes a body 1 and an adjustment component 2, the adjustment component 2 including a core 21 and a cover 25.
[0032] Please refer to Figure 1 , Figure 2 and Figure 3The main body 1 has a water outlet for spraying clean water. The adjustment component 2 is located at the water outlet of the main body 1. The interior of the core 21 includes a fixed section 22 and a water outlet section 23 connected sequentially along the liquid flow direction. The fixed section 22 is used to be installed on the water outlet of the main body 1 and thus fixed to the main body 1. The cover 25 covers the outside of the core 21, and one end of the cover 25 is connected to the water outlet end of the water outlet section 23.
[0033] In one embodiment, a second limiting part 251 is provided on the inner sidewall of the other end of the cover 25, and a plurality of first limiting parts 12 are provided on the end of the body 1 near the fixed section 22 along the water flow direction. In this way, by adjusting the cooperation relationship between the second limiting part 251 of the cover 25 and the plurality of first limiting parts 12 of the body 1, the water outlet section 23 of the core 21 is deformed, so as to achieve the purpose of adjusting the ejection pattern of the clean water flow.
[0034] In another embodiment, the inner wall of the other end of the cover 25 is provided with a plurality of second limiting portions 251 along the water flow direction, and a first limiting portion 12 is provided on the end of the main body 1 near the fixed section 22. In this way, by adjusting the cooperation relationship between the plurality of second limiting portions 251 of the cover 25 and the first limiting portion 12 of the main body 1, the water outlet section 23 of the core 21 is deformed, so as to achieve the purpose of adjusting the ejection pattern of the clean water flow.
[0035] Compared to the current requirement for users to prepare multiple replaceable nozzles to achieve different cleaning modes, this application sets an adjustment component 2 on the water outlet of the main body 1 and adjusts the cooperation relationship between the first limiting part 12 and the second limiting part 251 to achieve the purpose of the cleaning water flow being ejected in different forms. Users no longer need to prepare multiple nozzles, reducing costs and improving the user experience.
[0036] In one embodiment, the water outlet section 23 includes a deformation section 231 and a diffusion section 232. The two ends of the deformation section 231 are connected to the fixed section 22 and the diffusion section 232, respectively. The channel diameter of the deformation section 231 is flat, while the channel diameter of the diffusion section 232 gradually increases along the flow direction of the clean water. One end of the diffusion section 232 is connected to the deformation section 231, and the other end serves as the water outlet and is connected to the cover 25.
[0037] For example, the channel diameter of the deformation section 231 can be racetrack-shaped, rectangular, elliptical, or cylindrical, etc., thus changing the cleaning water flow into the deformation section 231 from a point flow to a linear flow, that is, changing the way the cleaning water impacts the oral cavity from point contact to line contact, effectively reducing irritation to the gums. The channel diameter of the diffusion section 232 can be conical, trumpet-shaped, stepped diffusion, fan-shaped, or frustum-shaped, etc., thus changing the cleaning water flow from the deformation section 231 into the diffusion section 232 from a linear flow to a diffused flow, thereby covering a wider range of water flow and cleaning complex areas such as interdental spaces and gingival sulci simultaneously, improving efficiency.
[0038] In one implementation, the inner cavity of the deformable section 231 is cylindrical, and the inner cavity of the diffuser section 232 is a frustum extending from one end near the deformable section 231 to the other. Understandably, the cylindrical deformable section 231 provides a channel of equal diameter to significantly increase the flow rate of the high-pressure cleaning water, while the frustum-shaped diffuser section 232, through its own gradual expansion characteristics, gradually reduces the water flow velocity, transforming the concentrated, high-pressure linear water flow into a gentler, diffused water flow, reducing irritation to the gums and improving user comfort.
[0039] As one embodiment, for ease of illustration, the two ends of the cover 25 are respectively designated as the first end (not shown in the figure) and the second end (not shown in the figure), wherein the first end (not shown in the figure) is connected to the water outlet of the main body 1, and one or more second limiting parts 251 are provided on the inner side wall of the second end (not shown in the figure).
[0040] Please refer to Figure 4 When the first limiting part 12 of the main body 1 and the second limiting part 251 of the cover 25 are in a matching relationship, such that the second end of the cover 25 (not shown in the figure) is relatively close to the water outlet of the main body 1, the deformation section 231 does not deform, and its inner cavity remains cylindrical. The clean water flow is not affected by the diffuser section 232 and is directly ejected in a columnar shape when flowing through the end of the deformation section 231. It can be understood that the nozzle is in a single-jet water spray mode at this time.
[0041] Please refer to Figure 5 When the first limiting part 12 of the main body 1 and the second limiting part 251 of the cover 25 are engaged, causing the second end of the cover 25 (not shown in the figure) to move relatively away from the water outlet of the main body 1, the inner cavity of the deformation section 231 will be compressed towards the water outlet of the main body 1, so as to form a frustum shape extending from the water outlet of the main body 1 to the water outlet end of the diffuser section 232 together with the inner cavity of the diffuser section 232. The clean water flows into the core 21 from the water outlet of the main body 1, and after being interfered with by the frustum-shaped inner cavity, it will be ejected in a scattering form. It can be understood that the nozzle at this time is in a scattering water flow spray mode.
[0042] By switching between the two modes, the needs of different users for different rinsing methods can be met, and precise control of water flow can be achieved, thereby improving the applicability of the oral irrigator and the user experience.
[0043] Please refer to Figure 6 In one embodiment, the end of the main body 1 near the fixed section 22 is recessed towards the liquid channel to form a positioning groove 13. The fixed section 22 has a snap-fit part 221 at the end away from the outlet of the main body 1. By placing the snap-fit part 221 in the positioning groove 13, the fixed section 22 is tightly fitted to the outlet of the main body 1 and fixed relative to the main body 1. In this way, the adjusting component 2 can be stably fitted onto the main body 1, thereby preventing the high-pressure cleaning water flow from spraying out of the outlet of the main body 1 and causing it to fall off due to the impact force.
[0044] In one embodiment, the snap-fit portion 221 is an annular protrusion, and the positioning groove 13 is an annular recess, with the width of the positioning groove 13 being less than or equal to the width of the snap-fit portion 221. It can be understood that the closed structure of the annular protrusion and the groove forms a 360° uniform force distribution, which is more resistant to water backflow or torsional forces during user operation compared to asymmetrical snap-fits. It can maintain a stable connection even under high-frequency vibration, preventing the core 21 from accidentally loosening. When the width of the positioning groove 13 is less than or equal to the width of the snap-fit portion 221, the snap-fit portion 221 inserts into the positioning groove 13, forming a slight interference fit. This effectively prevents cleaning water from seeping out from the joint, avoiding affecting the cleaning effect or causing internal structural corrosion.
[0045] In one implementation, the first limiting part 12 is a hemispherical protrusion, and the second limiting part 251 consists of two consecutive hemispherical grooves. Thus, the user can freely switch the two second limiting parts 251 of the cover 25 according to their own needs, allowing either second limiting part 251 to engage with the first limiting part 12 of the body 1, thereby driving the compression and resetting of the deformation section 231, allowing the cleaning water flow to switch between a diffused water flow and a linear water flow. The spherical symmetry of the hemispherical structure allows the cover 25 to be adjusted without precise alignment; the protrusion automatically slides into the groove, enabling blind operation and improving user convenience.
[0046] In one embodiment, the first limiting part 12 is an annular protrusion, and the second limiting part 251 consists of two consecutive annular grooves, the width of which is less than or equal to the width of the first limiting part 12. It can be understood that the closed structure of the annular protrusion and grooves forms a 360° uniform force distribution, which is more resistant to water backflow or torsional forces during user operation compared to asymmetrical snap-fits. It maintains a stable connection even under high-frequency vibration, preventing the cover 25 from accidentally loosening. When the width of the groove in the second limiting part 251 is less than or equal to the width of the first limiting part 12, a slight interference fit is formed when the second limiting part 251 is fitted onto the first limiting part 12. This prevents cleaning water from leaking out from the joint between the first limiting part 12 and the second limiting part 251 when it leaks from the gap between the first and fixed sections 22, thus avoiding affecting the cleaning effect or causing internal structural corrosion.
[0047] In one implementation, when the core 21 and the cover 25 are an integral structure, the structure is highly stable, and the deformation or repositioning of the deformation segment 231 is entirely controlled by the elasticity of the material itself, resulting in more precise switching. Furthermore, the integrally molded core 21 and cover 25 have no seams, preventing high-pressure cleaning water from leaking through the assembly gaps of the separate structures. When the core 21 and cover 25 are separate structures, the user can replace either the core 21 or the cover 25 individually, improving maintenance economy. Moreover, the core 21 and cover 25 of the separate structure can be manufactured using optimized materials; for example, the core 21 can be made of silicone soft rubber, and the cover 25 can be made of ABS plastic, maximizing the performance advantages of different materials.
[0048] As one embodiment, this application also provides a water flosser, which includes a water flosser body and a nozzle as described above. The output end of the water flosser body is connected to the water inlet end of the main body 1. Thus, when the water flosser is working, the cleaning water flow is pumped from the water flosser body to the water inlet end of the nozzle, and then sprayed out from the water outlet of the main body 1. The cleaning water flow sprayed from the water outlet of the main body 1, after passing through the adjustment component 2, will be ejected in a linear water flow or a diffused water flow according to the matching relationship between the first limiting part 12 and the second limiting part 251 currently adjusted by the user. The user no longer needs to prepare multiple nozzles, reducing costs and improving the user experience.
[0049] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
