[0044] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0045] See also Figure 1 In a first aspect, an embodiment of the present application provides a water flosser 100 that uses pulsed water flow to clean the user's teeth and interdental spaces. The water flosser 100 includes a water flosser body 1 and a water tank 2.

[0046] The irrigator body 1 is the main part of the irrigator 100, and a water storage chamber is formed inside the water tank 2. The water stored in the water storage chamber is used by the irrigator 100. During the use of the irrigator 100, water is drawn out from the water tank 2, and after being pressurized by the compression pump of the irrigator body 1, a high-pressure water flow is formed, which is sent to the teeth and gums through the nozzle to clean them. During the use of the irrigator 100, the high-pressure water flow can easily flush stains out of the oral cavity, and the irrigator body 1 can prevent stains and avoid the breeding of bacteria.

[0047] See also Figures 1 to 3 In some embodiments, the water flosser body 1 includes a movement 11 and a shell 12. The movement 11 is mainly composed of a motor, a water pump, a water circuit and a control panel. The function of the movement 11 is to drive the water pump through the motor to pressurize the water in the water tank 2 and spray it out through the water circuit to form a high-pressure water flow, thereby cleaning the teeth and the oral cavity. The shell 12 is fixed to the outside of the movement 11 to protect the movement 11.

[0048] The housing 12 includes a plastic lining 121 and a metal housing 122. The plastic lining 121 is a plastic part, and the plastic lining 121 is fixed to the outside of the movement 11. Specifically, the plastic lining 121 generally covers key parts of the movement 11, such as a motor, a water pump, etc., to form a protective barrier. The plastic lining 121 is mainly used to protect the movement 11 and prevent the movement 11 from being corroded by water or other liquids during operation, thereby improving the durability and stability of the movement 11. A connecting portion 1211 may be formed at one end of the plastic lining 121, and the connecting portion 1211 covers the port of the plastic lining 121, and the connecting portion 1211 can be connected to the movement 11 located inside the plastic lining 121, so that the plastic lining 121 can be firmly fixed on the movement 11 and will not fall off or shift during use. The softness and toughness of the plastic lining 121 can effectively reduce the impact of the outside world on the movement 11 and reduce the risk of damage to the movement 11.

[0049] The metal shell 122 is a metal part. For example, the metal shell 122 is aluminum or stainless steel, and the metal shell 122 is fixed to the outside of the plastic lining 121, so that the plastic lining 121 is at least partially fixed to the inner wall of the metal shell 122. The plastic lining 121 can be installed on the inner wall of the metal shell 122 by an injection molding process or a dispensing assembly process, so that the metal shell 122 can be connected to the movement 11 through the plastic lining 121, and the metal shell 122 has high strength, so that the water flosser 100 is not easily damaged when it falls, and can effectively protect the internal movement 11. Moreover, due to the processing technology of the metal shell 122, it is not easy to set a connecting structure, so it is necessary to connect and fix the metal shell 122 and the internal movement 11 by using the plastic lining 121. At the same time, the metal shell 122 has natural antibacterial properties, which can effectively inhibit the growth of bacteria on the water flosser body 1, maintain the hygiene and safety of the water flosser 100, and prevent the growth of bacteria on the water flosser body 1.

[0050] See also Figure 2 and Figure 4 In some embodiments, the oral irrigator body 1 further includes a top cover 13 and a bottom cover 14, which are generally made of the same material as the oral irrigator body 1, such as plastic or metal, to ensure the overall aesthetics and durability. The circumferential outer contour size and shape of the top cover 13 and the bottom cover 14 are adapted to the inner contour size and shape of the outer shell 12, so that the top cover 13 and the bottom cover 14 can be respectively assembled at the opposite ends of the outer shell 12. At the same time, the top cover 13 and the bottom cover 14 are also tightly fixed to the outer shell 12 by screwing, clamping or other connection methods, so that the movement 11 is sealed and fixed inside the outer shell 12, ensuring the sealing and waterproof performance of the oral irrigator 100.

[0051] Specifically, the top cover 13 is usually located at the top of the oral irrigator body 1, and the top cover 13 is generally covered on one end of the metal shell 122, and can be fixedly connected to one end of the plastic lining 121, so that the top cover 13 covers and protects the movement 11 and other internal components, and the bottom cover 14 is located at the bottom of the oral irrigator 100, and the bottom cover 14 is generally covered on the other end of the metal shell 122. Similarly, the bottom cover 14 can be fixedly connected to the other end of the plastic lining 121. The bottom cover 14 is usually used to close the oral irrigator body 1, and fix and protect the internal circuit board 18, battery and other components.

[0052] See also Figure 2 and Figure 4In some embodiments, the bottom cover 14 includes a bottom cover portion 141 and an insertion portion 142, wherein the bottom cover portion 141 is covered on one end of the metal shell 122 away from the top cover 13, the bottom cover portion 141 covers one end of the metal shell 122, the insertion portion 142 can be connected to the bottom cover portion 141, and the insertion portion 142 and the bottom cover portion 141 can be specifically integrally formed, and the circumferential outer contour size and shape of the insertion portion 142 are adapted to the inner contour size and shape of the plastic lining 121, so that the insertion portion 142 can be inserted into the plastic lining 121.

[0053] Combination Figure 3 and Figure 5 In some embodiments, a buckle 1421 may be provided on the outer wall of the insertion portion 142, and a groove 1212 may be provided on the inner wall of the plastic lining 121. When the insertion portion 142 is inserted into the plastic lining 121, the buckle 1421 may be inserted into the groove 1212 in a fitting manner, so that the insertion portion 142 and the plastic lining 121 are snapped together, thereby firmly connecting the bottom cover 14 and the plastic lining 121 together.

[0054] In some other embodiments, a groove 1212 may be provided on the outer wall of the extending portion 142 , and a buckle 1421 may be provided on the inner wall of the plastic lining 121 . The bottom cover 14 may be conveniently mounted on the outer shell 12 by providing the buckle 1421 and the groove 1212 .

[0055] See also Figure 1 , Figure 4 and Figure 6 In some embodiments, the circumferential outer contour size and shape of the bottom cover portion 141 match the inner contour size and shape of the outer shell 12, so that a portion of the bottom cover portion 141 is located inside the outer shell 12, and another portion of the bottom cover portion 141 is located outside the outer shell 12. Specifically, the bottom of the metal shell 122 may extend beyond the bottom of the plastic liner 121, and a portion of the bottom cover portion 141 is located inside the bottom of the metal shell 122. A clamping portion 1411 is provided on the portion of the bottom cover portion 141 located outside the metal shell 122. The clamping portion 1411 can be used to connect with the water tank 2 of the water flosser 100. For example, a clamping groove portion is provided on the water tank 2, and the clamping portion 1411 is clamped with the clamping groove portion, so that the water tank 2 is connected to the portion of the bottom cover portion 141 located outside the metal shell 122. The water tank 2 can be easily installed by providing the clamping portion 1411 on the bottom cover portion 141.

[0056] See also Figures 3 to 5In some embodiments, a positioning protrusion 1422 may be provided on the circumferential side wall of the insertion portion 142, a notch 123 is provided at one end of the shell 12, and the notch 123 can penetrate one end of the shell 12 along the axial direction of the shell 12, and the outer contour shape and size of the positioning protrusion 1422 can be adapted to the contour shape and size of the notch 123, and the notch 123 is used to accommodate the positioning protrusion 1422. When the insertion portion 142 is inserted into the shell 12, the positioning protrusion 1422 can be inserted into the notch 123, so that the bottom cover 14 can be accurately installed at one end of the shell 12, avoiding the bottom cover 14 and the shell 12 from being installed reversely, ensuring that the bottom cover 14 and the shell 12 can be firmly docked together, and can be easily installed.

[0057] Specifically, the shape of the alignment protrusion 1422 can be a structure with one part being circular and the other part being square. A notch 123 is provided at one end of the metal shell 122 and the plastic lining 121. When the metal shell 122 and the plastic lining 121 are assembled together, the notch 123 on the metal shell 122 can overlap with the notch 123 on the plastic lining 121, so that the two notches 123 form one notch 123. Here, the notch 123 can also play a role in installation positioning, which can prevent the metal shell 122 and the plastic lining 121 from being installed upside down, so that the metal shell 122 and the plastic lining 121 can be accurately assembled together.

[0058] See also Figure 4 and Figure 5 In some embodiments, a charging socket 1423 may be provided on the alignment protrusion 1422. Since the alignment protrusion 1422 is assembled at the notch 123 of the outer shell 12, the charging socket 1423 can be exposed from the outer shell 12, and the charging cable can be conveniently inserted into the charging socket 1423 to charge the dental flosser 100. Preferably, a cover adapted to the charging socket 1423 is also provided. When not charging, the charging socket 1423 can be covered with the cover to prevent water from entering the charging socket 1423.

[0059] See also Figures 2 to 6 In some embodiments, the insertion portion 142 of the bottom cover 14 is inserted into the plastic lining 121, and when the insertion portion 142 is snapped with the plastic lining 121, a sealing ring 15 is further provided between the insertion portion 142 and the plastic lining 121, and the sealing ring 15 is closer to the top cover 13 relative to the snapping position between the insertion portion 142 and the plastic lining 121. Specifically, the insertion portion 142 and the plastic lining 121 are snapped together by the buckle 1421 and the groove 1212, and the sealing ring 15 is located on the side of the groove 1212 facing the top cover 13, so that the sealing structure formed by the sealing ring 15 can seal the groove 1212 and the buckle 1421 outside the movement 11, which can increase the sealing performance and better prevent water from seeping into the movement 11.

[0060] See also Figure 2 and Figure 3 In some embodiments, the two opposite ends of the plastic lining 121 may extend from the ends of the metal shell 122, or the two opposite end surfaces of the plastic lining 121 may be flush with the two opposite end surfaces of the metal shell 122, or one end of the plastic lining 121 may extend from one end of the metal shell 122, while the end surface of the other end of the plastic lining 121 may be flush with the end surface of the other end of the metal shell 122, so that the two opposite end surfaces of the metal shell 122 do not exceed the two opposite end surfaces of the plastic lining 121, thereby avoiding direct contact between the end surface of the metal shell 122 and the user. Because the wall thickness of the metal shell 122 is relatively thin, the end surface of the metal shell 122 may scratch the user if it contacts the user.

[0061] See also Figure 2 In some embodiments, the thickness of the metal shell 122 is smaller than the thickness of the plastic lining 121 , which can reduce the weight and cost of the oral irrigator 100 .

[0062] Specifically, the thickness of the metal shell 122 is greater than or equal to 0.6 mm and less than or equal to 1.5 mm. The thickness range of the metal shell 122 enables the metal shell 122 to provide better protection to protect the movement 11 from external impact and damage, while the thickness of the plastic lining 121 is greater than or equal to 0.8 mm and less than or equal to 2 mm. The thickness range of the plastic lining 121 enables the plastic lining 121 to have excellent waterproof, dustproof and vibration absorption effects.

[0070] Specifically, the hard rubber area is usually used to form the main structure of the display unit 162. It has good hardness and stability and can protect the internal electronic components and the display screen 1622. The hard rubber area can also use specific processes and surface treatments to enhance its wear resistance, anti-fouling and waterproof properties to ensure that the display unit 162 can work normally in various environments.

[0071] The soft rubber button is usually arranged on the surface of the hard rubber area for the user to interact with the oral irrigator 100. The soft rubber button has good elasticity and touch, and the user can press it easily without feeling stiff or uncomfortable. In addition, the soft rubber button can also be designed in color and shape to increase the aesthetics and personalization of the product.

[0072] After the hard rubber area and the soft rubber button are integrally formed, they can be assembled in the installation opening 1221, which can ensure the stability and reliability of the entire display unit 162. The integrally formed design reduces the number of parts and gaps in the assembly process, reducing the possibility of product failure. At the same time, the design of the installation opening 1221 can also take into account the needs of waterproofing and dustproofing to ensure that the display unit 162 will not be corroded by water or other impurities during use.

[0073] See also Figure 2 , Figure 7 , Fig.10 and Fig.11In some embodiments, the interactive cover 16 may include a display cover 1621 and a display screen 1622. The display cover 1621 is in the shape of a rectangular plate structure. The display cover 1621 can be assembled in the mounting opening 1221, and the support portion 1213 can be supported on the bottom of the display cover 1621. An adhesive layer 17 may be provided between the display cover 1621 and the support portion 1213. The adhesive layer 17 can bond the display cover 1621 to the support portion 1213, so that the display cover 1621 can be firmly fixed in the mounting opening 1221, and the installation is also very convenient. It only needs to place the display cover 1621 in the mounting opening 1221 and press the display cover 1621 in the direction close to the support portion 1213.

[0074] The display screen 1622 can be assembled on top of the display cover 1621, and the adhesive layer 17 can extend between the display screen 1622 and the display cover 1621, so that the display screen 1622 can be fixed on the display cover 1621 through the adhesive layer 17, wherein the display screen 1622 has a display area and a non-display area, and the adhesive layer 17 is used to adhere the non-display area of ​​the display screen 1622 to the display cover 1621, thereby avoiding the display area of ​​the display screen 1622. While fixing the display screen 1622, the adhesive layer 17 can be prevented from blocking the display area of ​​the display screen 1622.

[0075] See also Figure 2 , Figure 5 and Figure 6 In some embodiments, when the insertion portion 142 of the bottom cover 14 is inserted into the plastic liner 121, the interactive cover 16 is located on one side of the insertion portion 142, and a charging socket 1423 is provided on a side surface of the insertion portion 142 facing away from the interactive cover 16. Along the direction perpendicular to the central axis of the plastic liner 121, the projection of the interactive cover 16 and the projection of the charging socket 1423 at least partially overlap, and a sealing ring 15 is provided on the circumferential outer wall of the insertion portion 142. The sealing ring 15 is located between the insertion portion 142 and the plastic liner 121, and the portion on the same side of the sealing ring 15 and the charging socket 1423 is farther away from the bottom cover 141 than the portion on the same side of the sealing ring 15 and the interactive cover 16.

[0076] Specifically, along the central axis direction of the plastic lining 121, part of the sealing ring 15 is located on the side of the charging socket 1423 away from the bottom cover portion 141, and the other part of the sealing ring 15 is located on the side of the interactive cover 16 close to the bottom cover portion 141, and the distance between the part of the sealing ring 15 located near the charging socket 1423 and the bottom cover portion 141 is farther than the distance between the part of the sealing ring 15 located near the interactive cover 16 and the bottom cover portion 141, so that the sealing ring 15 can separate the interactive cover 16 from the charging socket 1423, better seal the interactive cover 16, and prevent moisture from seeping into the interior of the movement 11 from the charging socket 1423.

[0077] See also Figure 2 and Fig.10 In some embodiments, the movement 11 may include a movement bracket and a circuit board 18. The movement bracket is the basic structure of the movement 11, which supports and fixes other components, and the movement bracket can be arranged inside the plastic lining 121, so that the plastic lining 121 can protect the movement bracket, reduce vibration and impact, and ensure the stability of the overall structure of the movement 11.

[0078] The circuit board 18 can be set on the movement bracket, and the circuit board 18 is located between the movement bracket and the interactive cover 16. The movement bracket provides a stable support for the circuit board 18, and the circuit board 18 interacts with the interactive cover 16 through electrical connection, so that various functions of the oral irrigator 100 can be realized through the circuit board 18.

[0079] See also Figure 2 and Fig.12 In some embodiments, the circuit board 18 and the interactive cover plate 16 can be electrically connected via a flexible printed circuit board 19. The flexible printed circuit board 19 can establish a stable electrical connection between the circuit board 18 and the interactive cover plate 16 while allowing the circuit board 18 and the interactive cover plate 16 to be moved or stacked together in a limited space. The flexible printed circuit board 19 ensures stable communication between the circuit board 18 and the interactive cover plate 16.

[0080] In addition, the flexible printed circuit board 19 has a redundant section 191, and the redundant section 191 is bonded to the interactive cover plate 16, and this connection method can further enhance the connection stability between the circuit board 18 and the interactive cover plate 16. The bonding can not only ensure that the redundant section 191 is mechanically fixed in place, but also prevent it from moving or falling off during use, thereby ensuring the reliability and durability of the electrical connection.

[0081] In some embodiments, the outer surface of the metal shell 122 may be provided with a wear-resistant and corrosion-resistant coating, which may increase the corrosion resistance of the metal shell 122 .

[0082] Specifically, when using the water flosser 100 for oral cleaning, water will naturally flow from the mouth to the outer surface of the water flosser body 1, especially the outer surface of the metal shell 122. Since the water may be mixed with cleaning liquid, dental plaque, saliva, food residues and other components, some of these substances are corrosive to metals. By providing a wear-resistant and anti-corrosion coating on the outer surface of the metal shell 122, the metal body can be effectively prevented from being corroded. To be more specific, the wear-resistant coating can enhance the hardness of the metal surface and reduce the damage caused by external friction, while the anti-corrosion coating can isolate the corrosive substances from direct contact with the metal, thereby greatly reducing the risk of corrosion.

[0083] In some embodiments, the metal shell 122 and the plastic lining 121 can be formed as one piece, so that the outer shell 12 fully utilizes the characteristics of both metal and plastic materials, thereby ensuring the structural strength of the outer shell 12 while also providing a certain buffering and shockproof effect for the movement 11.

[0084] At the same time, the one-piece molding design simplifies the manufacturing process and improves production efficiency. Specifically, compared with the method of separately manufacturing the metal shell 122 and the plastic lining 121 and then assembling them, the one-piece molding can reduce the assembly steps and the number of parts required, thereby reducing production costs and manufacturing time. The one-piece molding design also reduces the risk of failure due to poor assembly and improves product reliability.

[0085] See also Figure 1 and Figure 2 In some embodiments, the water flosser 100 may further include a medicine bottle 3, which may be connected to the water outlet of the water flosser body 1, so that the user can directly spray the medicine or oral care liquid in the medicine bottle 3 through the water spray function of the water flosser 100 to perform targeted cleaning or treatment of the oral cavity.

[0086] In some other embodiments, the medicine bottle 3 can also be connected to the water tank 2, so that the medicine liquid or oral care liquid will be mixed with the water in the water tank 2 of the water flosser 100, and then sprayed out through the water spraying function. The advantage of this design is that it can make the medicine liquid or care liquid more evenly distributed in the water flow of the water flosser 100, thereby ensuring that each water spray can achieve a good cleaning or treatment effect. At the same time, this design also allows users to adjust the ratio of medicine liquid or care liquid to water according to their needs to meet different oral cleaning needs.
