[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0022] See appendix Figure 1 -Appendix Figure 4This invention proposes a water flosser, which includes a body 1, a water nozzle 2, a display module 3, a main control board 4, and an operation panel 5. The body 1 includes a top surface 10 and a bottom surface 11 opposite to each other in its height direction, and a side surface 12 connecting the top surface 10 and the bottom surface 11. The water nozzle 2 is connected to the top surface 10 of the body 1. The display module 3 is located on the top surface 10 of the body 1 and can be transmitted light from or exposed on the top surface 10 of the body 1. The main control board 4 is located inside the body 1 and is electrically connected to the display module 3. The operation panel 5 is located on the body 1 and is at least partially exposed on the side surface 12 of the body 1.

[0023] Specifically, the main body 1 is equipped with a water tank to store water for rinsing teeth. The water nozzle 2 is connected to the pump body through a pipe inside the main body 1. The pump body is further connected to the water tank, so that when the pump body is working, the water in the tank is delivered to the water nozzle 2 to form a jet of water, thereby rinsing the teeth and oral cavity. The main body 1 is also equipped with a battery to provide power for the water flosser. The battery is electrically connected to the main control board 4 to supply power to the main control board 4, the display module 3, and the pump body. The main control board 4 is used to control the overall operation of the water flosser. On the one hand, it controls the display status and display content of the display module 3, and on the other hand, it controls the start and stop and working status of the pump body. The operation panel 5 consists of multiple buttons 50 integrated on the main control board 4. The multiple buttons 50 are used to receive operation commands input by the user and transmit operation signals to the main control board 4. The bottom surface 11 is set as a flat structure, so that the main body 1 can be placed upright on a flat support surface such as a table when not in use, thereby improving the stability of the placement. The side surface 12 is designed as a cylindrical curved surface structure, which forms the main grip area for the user, facilitating a comfortable grip and conforming to the palm. The top surface 10 of the body 1 forms the display interface of the display module 3. The top surface 10 of the body 1 is translucent, allowing the display module 3 to display its content outwards while operating inside the body 1, thus visualizing the working parameter information. In practice, the top surface 10 of the body 1 can be completely transparent, allowing the display light from the display module 3 to pass through the top surface 10 of the body 1. Alternatively, the top surface 10 can be a light-shielding structure with translucent properties, allowing the display light emitted by the display module 3 inside the body 1 to pass through the top surface 10 and be displayed outwards, thus presenting the working parameter information. The top surface 10 of the body 1 is visually opaque or nearly opaque, making it difficult for the user to observe the internal structure of the body 1 from the outside, thereby improving the overall integrity and aesthetics of the appearance. The water nozzle 2 and the display module 3 are staggered on the top surface 10. For example, the water nozzle 2 is positioned at the edge of the top surface 10 of the body 1, thereby reserving a larger display area for the display module 3 on the top surface 10 of the body 1 to display clearer parameter information. In other embodiments, the top surface 10 of the body 1 may also be provided with a window for the display module 3 to be exposed, so that the display module 3 is directly exposed on the top surface 10 of the body 1 for user viewing.

[0024] In summary, this water flosser, while ensuring normal water spraying and flossing functions, incorporates a display module 3 located inside the body 1, which displays information via light transmission through the top surface 10 of the body 1. Users can directly observe the content displayed on the top surface 10 of the body 1 from a natural viewing angle, obtaining the working status and parameter information of the water flosser without having to bend down or change their grip posture, thus improving readability during use. The control panel 5 is located on the side 12 of the body 1, which also serves as the user's main grip area, allowing for parameter adjustment and function operation while holding the water flosser with one hand, enhancing convenience and continuity of operation. The bottom surface 11 is designed as a flat structure for placement, ensuring the water flosser can be stably placed on a table or other support surface when not in use, preventing tipping or rolling. Through the combined structure of the top surface 10 display, the side 12 grip operation, and the bottom 11 placement, the overall convenience and user experience of the water flosser during use, operation, and storage are significantly improved. In other embodiments, the bottom surface 11a of the body 1 can also serve as one of the connection structures for connecting to the water tank.

[0025] See appendix Figure 1 -Appendix Figure 2 In some embodiments, the display module 3 is located on the top surface 10 of the body 1 near the operation panel 5, and the water nozzle 2 is located on the top surface 10 away from the operation panel 5.

[0026] Specifically, the control panel 5 is located on the side 12 of the body 1. The side 12 also serves as the user's primary grip area. In actual use, the user holds the device by covering the side 12 with their palm, with their thumb naturally close to and in contact with the control panel 5, facilitating one-handed operation of the buttons 50 and function control. Since the control panel 5 is positioned closer to the user during use, the display module 3 is located on the top surface 10 of the body 1, near the control panel 5. This positions the display module 3 more closely to the user's line of sight, allowing for simultaneous observation of displayed information during operation. The water nozzle 2 is located on the top surface 10 of the body 1, away from the control panel 5. This position of the water nozzle 2 on the top surface 10 of the body 1 is offset from the user's line of sight, preventing the water nozzle 2 from structurally obstructing the display module 3 and ensuring its visibility and integrity during use.

[0027] See appendix Figure 1 -Appendix Figure 2 In some embodiments, the top surface 10 of the body 1 is an inclined surface, and the side of the top surface 10 closer to the operation panel 5 is lower than the side away from the operation panel 5. The display module 3 is located on the side of the top surface 10 of the body 1 closer to the operation panel 5, and the water nozzle 2 is located on the side of the top surface 10 of the body 1 away from the operation panel 5.

[0028] Specifically, the top surface 10 of the main body 1 is designed with an inclined structure, so that when the main body 1 is held and used by the user, the top surface 10 of the main body 1 is no longer vertically upward, but tilted towards the user's head. Corresponding to the tilted shape of the top surface 10 of the main body 1, the display module 3 is installed in an inclined manner inside the main body 1, so that the light-emitting surface of the display module 3 is roughly parallel to the tilt direction of the top surface 10 of the main body 1, thereby ensuring that the display content can be stably and clearly displayed through the top surface 10 of the main body 1. When the user holds the main body 1 with one hand and operates it through the operation panel 5 on the side 12, the main body 1 is in a natural forward tilt state, and the tilt direction of the top surface 10 of the main body 1 is closer to the user's line of sight, so that the user can observe the display information of the display module 3 without raising or significantly adjusting the wrist angle. The display module 3 is located on the top surface 10 of the body 1, close to the operation panel 5, so that the display area is closer to the user's line of sight in space; the water nozzle 2 is located on the top surface 10 of the body 1, away from the operation panel 5, so that the position of the water nozzle 2 on the top surface 10 of the body 1 is far away from the area where the user's line of sight is concentrated, thereby avoiding visual interference and obstruction to the display module 3.

[0029] See appendix Figure 1 -Appendix Figure 4 In some embodiments, the top surface 10 of the body 1 is provided with a light-transmitting area 100 corresponding to the display module 3.

[0030] Specifically, the top surface 10 of the body 1 is used to allow the display light emitted by the display module 3 to be displayed outwards, and the light-transmitting area 100 is used to form a light-emitting channel for display information. In specific implementations, the top surface 10 of the body 1 can be entirely configured as a light-transmitting structure, allowing the display light from the display module 3 to be displayed outwards within the area of ​​the top surface 10 of the body 1; alternatively, the top surface 10 of the body 1 can only form a light-transmitting area 100 at the position corresponding to the display module 3, while the rest of the top surface 10 of the body 1 remains opaque, allowing the display content of the display module 3 to be displayed through partial light transmission. In the case of partially forming a light-transmitting area 100, the light-transmitting area 100 can be achieved by setting a light-transmitting plate, which can be made of light-transmitting materials such as glass or resin, to cover the corresponding position of the display module 3 and allow the display light to pass through; the light-transmitting area 100 can also be achieved by forming a through hole in the top surface 10 of the body 1, allowing the display light from the display module 3 to be displayed outwards through the through hole.

[0031] See appendix Figure 1 -Appendix Figure 4In some embodiments, the body 1 includes a housing 13, a mounting base 6 installed inside the housing 13, and a top cover 14 covering the top of the housing 13; the top surface 144 of the top cover 14 is the top surface 10 of the body 1, and the top cover 14 is provided with mounting holes 143 for installing water nozzles 2; the mounting base 6 is used to install the display module 3; the main control board 4 is installed inside the housing 13 and is located between the mounting base 6 and the bottom surface 11 of the body 1.

[0032] Specifically, the housing 13 has a cavity 130 extending through both ends along its height, which accommodates the internal functional components of the water flosser. A mounting base 6 is positioned within the cavity 130 near the top of the housing 13 and is bolted to the housing 13 for stable support and reliable positioning. A top cover 14 covers the top of the housing 13, placing the mounting base 6 within the internal space formed by the housing 13 and the top cover 14. This prevents the mounting base 6 from being directly exposed, protecting the internal structure and enhancing the overall appearance. After covering the housing 13, the top surface 144 of the top cover 14 forms the top surface 10 of the body 1, supporting the display function and serving as the interface for the user to view displayed information. The top cover 14 has mounting holes 143 at its edge for mounting the water nozzle 2, allowing the water nozzle 2 to be fixed to the top cover 14 and connected to the internal water system of the body 1. The display module 3 is mounted on the mounting base 6 and located on the side of the mounting base 6 away from the cavity 130, so that the display module 3 is close to the top cover 14 in spatial position, thereby facilitating the display light to be displayed outward through the top cover 14. The main control board 4 is set in the cavity 130 of the housing 13 and is located between the mounting base 6 and the bottom surface 11 of the body 1, so that the main control board 4 forms a layered arrangement with the display module 3 inside the body 1, which is conducive to the rational use of internal space and the orderly layout of wiring connections.

[0033] See appendix Figure 2 -Appendix Figure 4 In some embodiments, the mounting base 6 includes a base body 60 and a support portion 61 provided on the mounting base 6; the base body 60 is installed inside the housing 13; the support portion 61 is used to support the display module 3; the top cover 14 is provided with a mating hole 142, which is fitted around the outer periphery of the display module 3 and cooperates with the support portion 61 to limit the position of the display module 3.

[0034] Specifically, the base 60 is bolted and fixed inside the housing 13, forming a stable mounting base for the mounting seat 6 within the housing 13. The support portion 61 is located on the side of the base 60 away from the cavity 130 of the housing 13, positioned close to the top cover 14 to support the display module 3 and position it near the top surface 144 of the top cover 14. The display module 3 is placed on the support portion 61, which supports it from below. A mating hole 142 is formed on the inner wall of the top cover 14. In the assembled state, the mating hole 142 fits around and surrounds the display module 3 from the outer periphery, creating a mating relationship between the outer periphery of the display module 3 and the mating hole 142, thereby restricting the display module 3 in the radial direction. Through the support from below by the support portion 61 and the peripheral restraint of the mating hole 142, the display module 3 achieves a stable mounting state inside the housing 1.

[0035] See appendix Figure 2 -Appendix Figure 4 In some embodiments, a limiting platform 1420 is provided in the mating hole 142, and a plurality of limiting protrusions 33 that cooperate with the limiting platform 1420 are provided on the outer wall of the display module 3. The limiting platform 1420 abuts against the plurality of limiting protrusions 33 to limit the position of the display module 3 relative to the support portion 61.

[0036] Specifically, the limiting platform 1420 is located inside the mating hole 142 and extends along the circumferential direction of the display module 3 to form a ring-shaped or segmented structure, used to restrict the display module 3 in the axial direction. Multiple limiting protrusions 33 are provided on the outer wall of the display module 3, distributed at intervals along the outer periphery of the display module 3, and in the assembled state, they abut against the limiting platform 1420. When the top cover 14 is closed, the limiting platform 1420 abuts against the multiple limiting protrusions 33 downwards in the axial direction, causing the display module 3 to be pressed against the support portion 61. Through the cooperation of the limiting platform 1420 and the multiple limiting protrusions 33, the position of the display module 3 in the axial direction is limited. Simultaneously, the multiple limiting protrusions 33 form a multi-point contact structure, allowing the display module 3 to evenly distribute the load when under force, avoiding loosening or displacement caused by single-point force.

[0037] See appendix Figure 2 -Appendix Figure 4 In some embodiments, the mounting base 6 further includes a wiring hole 62 penetrating the base body 60, and the support portion 61 includes a fixing ring 610 protruding from the base body 60, the fixing ring 610 being arranged around the wiring hole 62; the end of the fixing ring 610 away from the base body 60 is used to support the display module 3; the water flosser also includes a wire 7, the wire 7 passing through the wiring hole 62 and connecting the display module 3 and the main control board 4.

[0038] Specifically, a wiring hole 62 is provided through the base 60 to provide a passage for the wire 7, enabling an electrical connection between the display module 3 and the main control board 4. The inner diameter of the wiring hole 62 is approximately the same as the inner diameter of the retaining ring 610, allowing the wire 7 to pass straight through the position corresponding to the retaining ring 610 and the wiring hole 62, thus avoiding significant bending of the wire 7 during the wiring process. Compared to a smaller diameter structure, the larger diameter wiring hole 62 facilitates the wiring and routing of the wire 7, and also provides space for fine-tuning the position of the display module 3 during assembly, thereby improving assembly convenience. Since the top surface 10 of the body 1 is set as an inclined surface in some embodiments, the end of the fixing ring 610 away from the base 60 can be set as an inclined shape in the structural design. After the display module 3 is installed on the fixing ring 610, the display module 3 is arranged in an inclined state with the fixing ring 610, so that the display surface of the display module 3 matches the inclined direction of the top surface 10 of the body 1, thereby ensuring that the display information has a good display angle when it is transmitted through the top surface 10 of the body 1.

[0039] See appendix Figure 2 -Appendix Figure 4 In some embodiments, the support portion 61 further includes an elastic ring 611 sleeved on the fixing ring 610, the elastic ring 611 being located between the display module 3 and the fixing ring 610.

[0040] Specifically, the elastic ring 611 is made of a material with elastic deformation capability, such as silicone, rubber, or thermoplastic elastomer, enabling it to undergo elastic compression and rebound under stress. The elastic ring 611 is sleeved on the fixed ring 610 and located between the display module 3 and the fixed ring 610, forming an elastic support layer between them. In the assembled state, the display module 3 is supported by the elastic ring 611, which is pressed against the display module 3 in the axial direction, generating an upward elastic support force. Due to the coefficient of friction of the elastic material surface, the elastic ring 611, while supporting the display module 3, also increases the friction between the bottom of the display module 3 and the support portion 61, making the positioning of the display module 3 on the support portion 61 more stable. The elastic ring 611 can also absorb the dimensional deviations generated during the assembly process and buffer vibration or impact during use; the ring structure of the elastic ring 611 itself ensures that the wiring hole 62 is not blocked, which is conducive to the wire 7 passing through the wiring hole 62.

[0041] See appendix Figure 2 -Appendix Figure 4In some embodiments, the elastic ring 611 includes an elastic body 6110 and a connecting groove 6111 and a first limiting groove 6112 provided on the elastic body 6110; the inner wall of the fixed ring 610 is provided with a first limiting part 6101 and a second limiting part 6102, the connecting groove 6111 is fitted into the fixed ring 610, and the first limiting groove 6112 cooperates with the first limiting part 6101 to restrict the rotation of the elastic ring 611, and the elastic body 6110 cooperates with the second limiting part 6102 to restrict the movement of the elastic ring 611 toward the wiring hole 62.

[0042] Specifically, a connecting groove 6111 is provided on one end wall of the elastic body 6110. The connecting groove 6111 is an annular groove structure extending circumferentially along the elastic body 6110. The connecting groove 6111 is used to fit around the outer periphery of the fixing ring 610 during assembly, thereby enabling the elastic ring 611 to be stably positioned on the fixing ring 610. A first limiting groove 6112 is provided on the side wall of the elastic body 6110. The first limiting groove 6112 extends along the axial direction of the elastic body 6110 to form a straight groove structure. A first limiting part 6101 is provided on the inner wall of the fixing ring 610. The first limiting part 6101 is a straight protrusion structure extending along the axial direction of the fixing ring 610. The first limiting groove 6112 and the first limiting part 6101 are engaged with each other in the assembled state, thereby restricting the circumferential rotation of the elastic ring 611 relative to the fixing ring 610. The second limiting part 6102 is disposed on the inner wall of the fixing ring 610. The second limiting part 6102 is an annular boss structure extending along the circumferential direction of the fixing ring 610. When the connecting groove 6111 is fitted onto the fixing ring 610, one end wall of the elastic body 6110 is supported by the annular boss, so that the elastic ring 611 is supported in the axial direction, thereby restricting the movement of the elastic ring 611 towards the wiring hole 62. Through the dual cooperation of rotational limiting and axial limiting of the elastic ring 611, the installation state of the display module 3 on the fixing ring 610 is more stable, thereby improving the reliability and operational stability of the overall structure.

[0043] See appendix Figure 2 -Appendix Figure 4 In some embodiments, the top cover 14 includes an inner cover plate 140 and an outer cover plate 141; the inner cover plate 140 is provided with a display window 1400 corresponding to the display module 3 and a mating hole 142 communicating with the display window 1400, the mating hole 142 is fitted around the outer periphery of the display module 3 and fixes the display module 3 on the mounting base 6; the outer cover plate 141 is an integral light-transmitting structure, or the part of the outer cover plate 141 corresponding to the display window 1400 is a light-transmitting structure.

[0044] Specifically, the top cover 14 adopts a double-layer cover structure, formed by an inner cover 140 and an outer cover 141. The inner cover 140 is installed on the top of the housing 13, and the inner wall of the inner cover 140 forms a mating hole 142. The mating hole 142 is used to fit and surround the outer periphery of the display module 3, so that the display module 3 is limited in position within the inner cover 140. A display window 1400 is also formed on the inner cover 140, which communicates with the mating hole 142, allowing the display light emitted by the display module 3 located within the mating hole 142 during operation to be transmitted outward through the display window 1400. The outer cover 141 is located on the outside of the inner cover 140, and the outer surface of the outer cover 141 is the top surface 144 of the outer cover 14, forming the top surface 10 of the housing 1, which serves as the external surface interface for the user to observe the displayed information. The light emitted by the display module 3 passes through the display window 1400 and is further projected outward through the outer cover plate 141, allowing the user to observe the displayed information on the top surface 144 of the outer cover 14. The outer cover plate 141 can be an overall light-transmitting structure, allowing all the display light to pass through it; alternatively, it can be set to be light-transmitting only at the position corresponding to the display window 1400, while the remaining areas remain opaque, thus maintaining the overall integrity of the top cover 14's appearance while ensuring the display effect. The outer cover plate 141 can be an overall light-transmitting structure or a partially light-transmitting structure, especially when using a light-transmitting but opaque material, such as a black light-transmitting material, making it difficult for the user to observe the inner cover plate 140 and the internal structure of the display module 3 from the outside, thereby improving the overall integrity and aesthetics of the appearance while still ensuring the clear display of information from the display module 3. The inner cover plate 140 and the outer cover plate 141 can be manufactured separately and then assembled, or they can be made of different materials through a one-piece injection molding process, thus providing greater flexibility in terms of appearance design, material selection and manufacturing process.

[0045] See appendix Figure 2 -Appendix Figure 4 In some embodiments, the display module 3 includes a display circuit board 30, a light-blocking plate 31, and a film 32 stacked on top of each other; the display circuit board 30 is provided with a plurality of light-emitting elements 300 spaced apart; the light-blocking plate 31 is provided with a plurality of light-transmitting holes 310 extending along its thickness direction, the plurality of light-transmitting holes 310 are isolated from each other, and the plurality of light-transmitting holes 310 are arranged in a one-to-one correspondence with the plurality of light-emitting elements 300.

[0046] Specifically, the light-blocking plate 31 is configured as a plate-like structure with a thickness greater than that of the display circuit board 30, so that the multiple light-transmitting holes 310 on the light-blocking plate 31 form a through-hole structure with a certain depth in the thickness direction. After the display circuit board 30 and the light-blocking plate 31 are stacked, they are fixedly connected by bolts to form a stable overall structure. Multiple light-emitting elements 300 are disposed on the display circuit board 30 and are respectively arranged corresponding to the light-transmitting holes 310 on the light-blocking plate 31, so that the light emitted by each light-emitting element 300 can be emitted outward along the channel direction of the corresponding light-transmitting hole 310. Since the light-transmitting holes 310 have a certain depth in the thickness direction, the light-transmitting holes 310 spatially isolate the light path, so that the light emitted by each light-emitting element 300 is independent during transmission, avoiding the mixing of light between adjacent light-emitting elements 300, making the information boundary displayed by the display module 3 on the outer cover plate 141 clearer, and avoiding light crosstalk. Film 32 is attached to the side of light-blocking plate 31 away from display circuit board 30. A light-transmitting area 100 corresponding to the display content is formed on film 32, used to define the display pattern, ensuring that light emitted by light-emitting element 300 only passes through the preset area, thereby shaping the display content and improving the clarity and contrast of the displayed information. The coordinated arrangement of light-blocking plate 31 and film 32 further enhances the stability and quality of the display effect of display module 3. In this structure, light-blocking plate 31 also serves as the main supporting structure of display module 3. Multiple limiting protrusions 33 are formed on the outer peripheral wall of light-blocking plate 31. These limiting protrusions 33 abut against the limiting platform 1420 within the mating hole 142 of top cover 14, thereby limiting the display module 3 in the axial direction, ensuring reliable axial positioning and structural support for the display module 3 in the installed state.
