Description

Technical Field

[0001] This utility model relates to the field of oral irrigator technology, and in particular to a magnetic charging component and an oral irrigator. Background Technology

[0002] Traditional water flossers generally use wired or contact charging designs, requiring a charging port or metal contacts on the device body. However, these charging methods commonly have physical contact defects. For example, such charging requires openings in the water flosser body, which compromises the product's seal. With prolonged use, moisture penetration can lead to corrosion of internal circuitry, reducing the device's lifespan. Simultaneously, the recessed structure at the charging port easily accumulates toothpaste foam and bacteria, increasing cleaning difficulty and hygiene risks. Furthermore, physical plug-and-play charging is prone to poor contact due to interface wear, and exposed metal contacts may pose a short circuit risk when exposed to water. These design flaws directly impact the user experience and product reliability. Utility Model Content

[0036] Please see below. Figures 1-6 The present invention provides a magnetic charging component 10, which is applied to a dental flosser 20, and specifically includes:

[0037] The charging lower casing 11 is hollow and opens towards the top.

[0038] The charging upper shell 12 covers the charging lower shell 11, is hollow and opens towards the bottom. The charging lower shell 11 and the charging upper shell 12 together form an installation cavity. The top of the charging upper shell 12 is provided with a charging magnetic surface 121.

[0039] The transmitting coil 13 is installed in the middle of the mounting cavity;

[0040] Magnet 14 is installed in the mounting cavity and located on the side of transmitting coil 13;

[0041] The transmitting coil 13 is used to transmit electrical energy to the water flosser 20, and the magnet 14 is used to provide magnetic attraction.

[0042] In this embodiment, the charging lower shell 11 and the charging upper shell 12 together form an installation cavity, and the transmitting coil 13 and the magnet 14 are effectively integrated in the installation cavity, thereby providing a stable magnetic attraction force and ensuring that the charging magnetic surface 121 is tightly attached to the water flosser 20. The magnetic charging function is realized without drilling, thereby improving charging efficiency and safety, while simplifying the assembly process and enhancing the overall aesthetics and user experience of the product.

[0043] In one embodiment, the magnetic charging assembly 10 further includes:

[0044] PCBA board 15 is installed in the mounting cavity and is electrically connected to the transmitting coil 13;

[0045] The power cord 16 is connected to the PCBA board 15 at one end and extends to the outside of the magnetic charging assembly 10 and is connected to the power supply at the other end.

[0046] In this embodiment, PCBA board 15 is responsible for power conversion and control to ensure stable output; power line 16 provides external power connection to ensure continuous power supply.

[0047] In one embodiment, a plurality of positioning mounting posts 111 are provided inside the charging lower housing 11, and the PCBA board 15 is mounted between the plurality of positioning mounting posts 111.

[0048] At least one positioning mounting post 111 has a positioning protrusion 112 on its top, and the PCBA board 15 has a positioning mounting hole 151 that matches the positioning protrusion 112.

[0049] In this embodiment, the precise cooperation between the positioning mounting post 111 and the positioning protrusion 112 enables the PCBA board 15 to be securely installed in the mounting cavity and ensures precise docking between the components, thereby improving the stability and durability of the overall structure.

[0050] In specific application scenarios, the number and distribution of the positioning mounting posts 111 and positioning protrusions 112 can be flexibly adjusted according to actual needs to adapt to PCBA boards 15 of different sizes and shapes. For example, four positioning mounting posts 111 can be set inside the charging lower shell 11, respectively positioned at the top, bottom, left, and right, so that the PCBA board 15 can be snapped between the four positioning mounting posts 111, ensuring that the PCBA board 15 is fixed in the center within the mounting cavity. Positioning protrusions 112 are set on two of the opposing positioning mounting posts 111 to precisely align with the positioning mounting holes 151 on the PCBA board 15, further optimizing the fixing effect between components, improving the stability and durability of the overall structure, and ensuring the reliability and safety of the charging process.

[0051] In a specific embodiment, the positioning mounting post 111 is provided with a stepped structure for engaging the PCBA board 15, thereby restricting the movement of the PCBA board 15 on the horizontal plane.

[0052] In addition, the side of the charging lower cover 11 is provided with a wire hole 113 for the power cord 16 to extend.

[0053] In one embodiment, the bottom of the charging upper shell 12 is provided with a magnet 14 mounting groove 122, through which the magnet 14 is embedded and fixed, ensuring that the magnet 14 is stably and accurately positioned at the bottom of the charging upper shell 12. It is understood that the design of the magnet 14 mounting groove 122 matches the shape of the magnet 14.

[0054] In one embodiment, two magnets 14 are provided, and the two magnets 14 are symmetrically arranged on both sides of the transmitting coil 13. The two magnets 14 are symmetrically fixed on both sides of the transmitting coil 13 through the magnet mounting slots 122, forming a uniform magnetic field distribution, enhancing the magnetic attraction force, ensuring that the charging magnetic surface 121 is in close contact with the oral irrigator 20, and improving charging stability and safety.

[0055] In other embodiments, the number and distribution of magnets 14 can be adjusted according to actual needs. For example, four magnets 14 can be set and located at the four corners of the transmitting coil 13 respectively to further optimize the magnetic field distribution, enhance the magnetic attraction effect, and ensure that the charging process is more stable and reliable; or only one magnet 14 can be set on the side of the transmitting coil 13 (or stacked on the center of the transmitting coil 13) to simplify the structure, reduce weight and save costs.

[0056] In one embodiment, a coil mounting portion 123 is provided at the center of the bottom of the charging upper shell 12, and a coil mounting hole 131 matching the coil mounting portion 123 is provided at the center of the transmitting coil 13. Through the cooperation between the coil mounting portion 123 and the coil mounting hole 131, the transmitting coil 13 can be precisely fixed at the center of the bottom of the charging upper shell 12, ensuring that the transmitting coil 13 is tightly attached to the bottom of the charging upper shell 12, and avoiding the decrease in charging efficiency and unstable charging caused by coil displacement.

[0057] In one embodiment, the shape of the charging magnetic surface 121 is adapted to the shape of the charging surface of the water flosser 20. This shape adaptation design not only ensures a tight fit during charging and guarantees charging speed, but also makes it easy for users to quickly identify and correctly place the water flosser 20, avoiding charging failure or reduced efficiency due to misplacement.

[0058] In one embodiment, the lower charging shell 11 and the upper charging shell 12 are respectively provided with matching snap-fit ​​structures 17 on their sides. Through the cooperation of the upper and lower snap-fit ​​structures 17, the charging shell is stably assembled, preventing the shell from separating due to vibration or accidental collision during use.

[0059] This utility model embodiment also provides a water flosser 20, including the magnetic charging assembly 10 as described in any of the preceding claims. Furthermore, a receiving coil and a magnet are disposed on the inner side of the charging surface of the water flosser 20.

[0060] This embodiment achieves magnetic charging by setting corresponding transmitting coil 13 and receiving coil, as well as a magnet, on the magnetic charging assembly 10 and the water flosser 20 body, respectively, ensuring efficient and stable charging. Simultaneously, by placing the receiving coil and magnet inside the body, no holes are needed, ensuring a tight fit during charging while maintaining the overall aesthetics and waterproof performance of the device, thus enhancing user experience and ease of use.
