[0036] The water storage mechanism includes a water tank 12 and an end cap 23. The water tank 12 is a cavity structure with an opening at the top. The end cap 13 is detachably connected to the water tank 12 to seal the water tank 12 and prevent the liquid inside the water tank 12 from leaking out during use, thereby improving the stability of the water tank 12 during use. The end cap 23 ensures the smoothness of the shell 1, improves the aesthetics of the product, and further protects the water tank 12, making it convenient for users to add liquid to the water tank 12.

[0037] For further details, please refer to Figure 3The housing 1 is provided with a mounting base 14 for installing the battery 3. The mounting base 14 is fixed on the back cover 22. A sealing ring 15 is fixedly connected to the contact surface between the mounting base 14 and the back cover 22. The sealing ring 15 improves the sealing performance of the battery 3, prevents liquid from entering the mounting base 14 and causing the battery 3 to get damp, and improves the protection effect of the battery 3.

[0038] For further details, please refer to Figure 3 and Figure 7 The rear cover 22 has a sliding groove, and a push cover 16 that protects the nozzle seat 7 is slidably connected in the sliding groove. The outer wall of the push cover 16 has anti-slip texture for easy pushing. The push cover 16 can protect the nozzle seat 7 after the user removes the nozzle cap 10, reducing the problem of dust entering the nozzle seat 7 and affecting subsequent use. This helps to improve the effective service life of the nozzle seat 7 and facilitates long-term use. The anti-slip texture design increases friction and improves the user's experience of sliding the push cover 16.

[0039] For further details, please refer to Figure 3 and Figure 7 A movable rod 17 is elastically connected inside the slide groove. The movable rod 17 is provided with an elastic protrusion 18 to prevent the push cover 16 from shaking randomly. The movable rod 17 can dampen the movement of the push cover 16 inside the slide groove, avoiding the problem of the push cover 16 moving without being pushed, improving the positioning effect of the push cover 16, and also helping to improve the stability of the push cover 16 during use. The elastic protrusion 18 further improves the positioning effect.

[0040] For further details, please refer to Figure 3 The lower part of the housing 1 is also fixedly connected to a second PCBA board 19, which is electrically connected to the battery 3 and the first PCBA board 9. The front cover 2 is provided with a button 20 fixedly connected to the switch on the second PCBA board 19. The second PCBA board 19 is also provided with an indicator light holder 21. The front cover 2 is provided with a through groove for mounting the indicator light holder 21. The design of the button 20 makes it convenient for the user to start the first PCBA board 9 and the battery 3 through the second PCBA board 19. The design of the indicator light holder 21 makes it easy for the user to observe the usage mode of the humidifier, thus making it convenient for the user to operate.

[0041] For further details, please refer to Figure 3 The end cap 23 is detachably connected to the top of the housing 1. The bottom of the housing 1 is provided with a USB interface 24 that connects to the second PCBA board 19 to charge the battery 3. After the battery is depleted, the battery 3 can be powered through the USB interface 24, eliminating the need to replace the battery 3 after it is depleted, thus saving energy and protecting the environment.

[0042] For further details, please refer to Figure 6The top of the water tank 12 is detachably connected to a second waterproof ring 25. Two positioning blocks 26 are fixedly connected to the top of the second waterproof ring 25. The tank cover 13 is provided with positioning grooves that engage with the two positioning blocks 26. The second waterproof ring 25 further improves the sealing between the water tank 12 and the tank cover 13, reducing liquid leakage. The positioning grooves on the tank cover 13 can fix the position of the second waterproof ring 25, so that after the tank cover 13 is connected to the water tank 12, the second waterproof ring 25 will not move between the water tank 12 and the tank cover 13, which helps to improve the stability of the second waterproof ring 25 during use.

[0043] For further details, please refer to Figure 8 Inside the housing 1, a support frame 27 is also fixedly connected. A connecting rod 28 is rotatably connected to the support frame 27. A mounting frame 29 is rotatably connected to the connecting rod 28. The first PCBA board 9 is fixedly connected to the mounting frame 29. By setting the mounting frame 29, the position of the first PCBA board 9 can be restricted, which is conducive to improving the coordination between structures.

[0044] For further details, please refer to Figure 8 A rotating frame 30 is rotatably connected to the mounting slot, and the nozzle seat 7 is fixedly connected to the rotating frame 30. A torsion spring 31 is fixedly connected to the connection between the rotating frame 30 and the mounting slot. During the use of the humidifier, the user's hand will be on the housing 1, and the user may accidentally touch the button 20 and the nozzle cap 10. After the nozzle cap 10 is connected to the nozzle seat 7, the nozzle seat 7 and the mounting slot are connected by the rotating frame 30, so that the nozzle cap 10 and the housing 1 form a flexible connection. This avoids friction between the nozzle seat 7 and the nozzle cap 10 and the housing 1 when the user's hand is on the nozzle cap 10, which would affect the effective service life of the nozzle cap 10 and the nozzle seat 7. Since the mounting frame 29 is connected to the support frame 27 through the connecting rod 28, the first PCBA board 9 has a certain amount of movement space, which facilitates the overall movement of the mist absorption mechanism and plays a buffering role, which is conducive to improving the effective service life of the mist absorption mechanism.

[0045] The working principle of this invention is as follows: During use, the second PCBA board 19 is activated by the button 20 to start the first PCBA board 9 and battery 3. The design of the indicator light base 21 makes it easy for users to observe how the humidifier is used. The water storage mechanism introduces the liquid into the MESH atomizing plate 4 for atomization, and then sprays it out through the nozzle 6, which can achieve the spraying effect. Patients can treat themselves at home according to the doctor's prescription through the spraying mechanism. The mouthpiece 5 is set to meet different user needs. When the mouthpiece 5 is not in use, the mouthpiece 6 can be separated from the nozzle 6 for easy cleaning. During use, the user's hand will hold the housing 1. When the user's hand rests on the mouthpiece cap 10, friction will occur between the suction base 7, the mouthpiece cap 10, and the housing 1, affecting the effective service life of the mouthpiece cap 10 and the suction base 7. The connection of the mounting frame 29, the connecting rod 28, and the support frame 27 gives the first PCBA board 9 a certain amount of movement space, which facilitates the overall movement of the mist suction mechanism, plays a buffering role, and helps to improve the effective service life of the mist suction mechanism.

[0046] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
