[0033] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0034] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0035] Please see below. Figures 1-9 The present invention provides a quick-release water tank water flosser, specifically comprising:

[0036] The main body 10 has a water tank mounting part 11 and a water tank connecting part 12 on one side. A valve core abutment structure 121 is provided on the water tank connecting part 12.

[0037] The water tank assembly 20 is detachably installed on the water tank mounting part 11, and a water filling part 21 matching the water tank connection part 12 is provided on the side;

[0038] The flexible valve core assembly 30 is movably disposed within the water injection section 21, with one end facing the valve core abutment structure 121 and the other end provided with a sealing component 31;

[0039] When the water tank assembly 20 is disassembled, the elastic valve core assembly 30 closes the water injection section 21; when the water tank assembly 20 is installed in the water tank mounting section 11, the elastic valve core assembly 30 abuts against the valve core abutment structure 121 to release the closure and allow water to be injected.

[0040] In this embodiment, through the linkage design of the elastic valve core assembly 30 and the valve core abutment structure 121, the seal is automatically released for water filling during water tank installation and automatically restored to the sealed state during disassembly, ensuring leak-proof reliability during use. This simplifies the operation process of water tank installation and disassembly, reduces user maintenance difficulty, and improves overall ease of use and user experience.

[0041] Specifically, when the water tank assembly 20 is installed in place, the elastic valve core assembly 30 is squeezed by the valve core abutment structure 121, moves away from the water injection part 21, and causes a gap to be created between the sealing component 31 and the water injection part 21, thereby realizing the water injection function; conversely, when the water tank assembly 20 is disassembled, the elastic valve core assembly 30 is no longer squeezed, automatically springs back to the initial position, and the sealing component 31 re-closes the water injection part 21 to prevent water leakage in the water tank and ensure equipment safety.

[0042] In one embodiment, the valve core abutment structure 121 is open at one end abutting the elastic valve core assembly 30, and a filter screen 122 is provided on the top of the valve core abutment structure 121.

[0043] In this embodiment, after the valve core abutment structure 121 abuts against the elastic valve core assembly 30, water flows out from the water injection section 21 and flows into the internal pipe of the main body 10 through the opening of the valve core abutment structure 121 for user use. By setting a filter screen 122 at the opening, impurities in the water can be effectively filtered, preventing pipe blockage, extending the service life of the equipment, ensuring water quality cleanliness, and improving the flushing effect.

[0044] In one embodiment, magnets 40 are correspondingly provided on the inner side of the water tank mounting part 11 and the inner side of the water tank assembly 20. This embodiment achieves magnetic installation by providing magnets 40 on the inner sides of the water tank mounting part 11 and the water tank assembly 20 respectively. Based on this, when installing the water tank assembly 20, the user only needs to bring the water tank assembly 20 close to the main body 10, and the magnets 40 will automatically attract and align. Then, the valve core abutment structure 121 abuts against the elastic valve core assembly 30 to fill water for use. When disassembling the water tank assembly 20, simply pull the water tank assembly 20, and the magnets 40 will automatically separate, and the elastic valve core assembly 30 will spring back to close the water filling part 21. This simplifies the operation steps, realizes quick and convenient water tank installation and removal, and further optimizes the user experience.

[0045] In specific application scenarios, magnets 40 can be installed on the inner sides of the upper and lower ends of the water tank mounting part 11 to improve magnetic attraction stability and alignment accuracy, ensuring that the water tank assembly 20 can be stably installed in various usage environments and preventing accidental detachment due to vibration or tilting. Of course, the number and position of the magnets 40 in the water tank assembly 20 correspond to those in the water tank mounting part 11. Therefore, when magnets 40 are installed on the inner sides of the upper and lower ends of the water tank mounting part 11, magnets 40 should also be installed on the inner sides of the upper and lower ends of the water tank assembly 20 to ensure optimal magnetic attraction.

[0046] In other embodiments, the water tank assembly 20 and the main body 10 may also be connected by other means, such as snap-fit.

[0047] In one embodiment, the oral irrigator provided by this utility model further includes a water outlet assembly 50. The water outlet assembly 50 is provided with an inlet 51, an outlet pipe 52 and an outlet 53 connected in sequence. The inlet 51 is connected to the water storage chamber 22 in the water tank assembly 20. The outlet 53 is fixed to the inner wall of the water injection part 21. The elastic valve core assembly 30 is movably disposed in the outlet 53.

[0048] In this embodiment, by setting up a water outlet assembly 50, water from the water storage chamber 22 in the water tank assembly 20 is guided to the water injection section 21 for filling by using the water inlet 51, water outlet pipe 52, and water outlet 53 in the water outlet assembly 50 for rinsing. The elastic valve core assembly 30 is movably disposed in the water outlet assembly 50 to ensure that when the water tank assembly 20 is connected to the main body 10, the water inlet 51 is connected to the water storage chamber 22, and water flows smoothly into the water injection section 21; when disassembled, the valve core automatically closes the water outlet 53 to prevent leakage, improving ease of use and safety.

[0049] In one embodiment, the inner wall of the water injection section 21 is fixedly connected to the outer wall of the water outlet 53 by a snap-fit ​​connection. During assembly, the elastic valve core assembly 30 is first installed inside the water outlet assembly 50, and the various parts of the water outlet assembly 50 are assembled. Then, the water outlet assembly 50 is snapped onto the inner wall of the water injection section 21 to ensure a stable connection. Finally, the water tank assembly 20 is connected to the main body 10 to complete the installation.

[0050] In one embodiment, the resilient valve core assembly 30 includes a valve core body 32, the end of which near the valve core abutment structure 121 is hollowed out.

[0051] In this embodiment, by hollowing out one end of the valve core body 32, a fluid channel can be formed in the hollowed-out portion after the water tank assembly 20 is assembled onto the main body 10, facilitating smooth water flow. It is understood that the other end of the valve core body 32 is provided with a sealing structure to prevent water leakage when the water tank assembly 20 is disassembled.

[0052] In one embodiment, the elastic valve core assembly 30 further includes a spring 33. A spring 33 baffle 321 is provided at the valve core body 32 abutting against the valve core abutting structure 121. An annular abutting structure 531 protrudes from the inner wall of the outlet 53. The spring 33 is disposed between the spring 33 baffle 321 and the annular abutting structure 531.

[0053] In this embodiment, by setting a spring 33 between the spring 33 baffle 321 and the annular abutment structure 531, the spring 33 provides an elastic force for the elastic valve core assembly 30 to rebound, ensuring that the elastic valve core assembly 30 can rebound and close the water injection section 21 after the water tank assembly 20 is disassembled.

[0054] Specifically, when the water tank assembly 20 is separated from the main body 10, the elastic valve core assembly 30, under the action of the spring 33, drives the sealing component 31 to close the water outlet 53, preventing water leakage; when the water tank assembly 20 is connected to the main body 10, the elastic valve core assembly 30 is squeezed by the valve core abutment structure 121 and compresses the spring 33, so that the sealing component 31 is away from the water outlet 53, ensuring that the water flows smoothly into the main body 10.

[0055] In one embodiment, the sealing component 31 is a sealing ring disposed at the end of the valve core body 32 away from the valve core abutment structure 121, and the valve core body 32 is provided with a corresponding ring groove 322.

[0056] The diameter of the sealing ring after it is fitted into the ring groove 322 is larger than the inner diameter of the annular abutment structure 531.

[0057] In this embodiment, the diameter of the sealing ring after being fitted into the ring groove 322 is larger than the inner diameter of the annular abutment structure 531, ensuring that the sealing ring can effectively seal the annular abutment structure 531, thereby preventing water leakage when the water tank assembly 20 is disassembled.

[0058] In one embodiment, the water tank connection part 12 further includes a mounting groove 123, the valve core abutment structure 121 protrudes at the center of the mounting groove 123, and the water injection part 21 includes a circular flange 211 that matches the mounting groove 123.

[0059] In this embodiment, a stable connection between the main body 10 and the water tank assembly 20 is ensured by setting mounting grooves 123 and circular flanges 211 at the water tank connection part 12 and the water injection part 21 respectively for docking.

[0060] In one embodiment, a shaped waterproof ring 212 is fitted around the outer side of the circular flange 211. The shaped waterproof ring 212 achieves a seal when the water tank connection 12 and the water injection part 21 are connected, preventing water leakage when the water tank assembly 20 is installed and used.
