Among them, a water inlet pipe 15 is arranged inside the humidifier 1, and the transfer valve 2 is detachably connected to the water inlet pipe 15, and a water storage bottle 4 is detachably connected to the transfer valve 2. The water storage bottle 4 and the transfer valve 2 can be connected by a threaded connection method. Specifically, the water storage bottle 4 is a common plastic bottle with a threaded mouth in the consumer market, and the transfer valve 2 is provided with an internal thread adapted to the common plastic bottle with a threaded mouth in the consumer market. The water storage bottle 4 can be directly screwed onto the transfer valve 2 and transferred to the humidifier 1 through the transfer valve 2 to supply water to the humidifier 1.

[0053] Based on the above technical means: The water storage bottle 4 can be first connected to the transfer valve 2, and then the transfer valve 2 and the water storage bottle 4 are installed on the top of the humidifier 1. Using the water storage bottle 4 replaces the traditional water tank, simplifies the structure of the ventilator, and the water storage bottle 4 can be discarded after use without forming scale, ensuring the treatment effect of the ventilator.

[0054] In this embodiment, the water storage bottle 4 has a standard mouth diameter (such as PCO 1810 / 1881), and the internal thread on the transfer valve 3 is adapted to the plastic bottle with a standard mouth diameter. For example, it can be adapted to the PCO 1881 screw mouth of various mineral water bottles (such as Nongfu Spring, C'estbon and Wahaha, etc.).

[0055] Specifically, the transfer valve 2 includes a connector 21, a water stop valve 22, a valve core 23, and a first reset member 24. The connector 21 has a hollow structure and includes an upper part 211 and a lower part 212. The upper part 211 and the lower part 212 are of an integral structure and communicate with each other. An internal thread adapted to the screw thread of the water storage bottle 4 is provided on the inner wall of the upper part 211. A connecting ring 213 is provided inside the lower part 212, and two water inlets 214 are provided at the bottom of the lower part 212. The two water outlets are arranged oppositely. The valve core 23 is inserted into the connecting ring 213. One end of the valve core 23 is connected to the water stop valve 22, and a limiting circle 231 is provided at the other end. The first reset member 24 is sleeved on the valve core 23. One end of the first reset member 24 abuts against the connecting ring 213, and the other end abuts against the limiting circle 231.

[0056] Further, the water stop valve 22 is of a bowl-shaped structure. Both the water stop valve 22 and the valve core 23 are made of rubber. The water stop valve 22 is located above the lower part 212 and can block the lower part 212. The first reset member 24 is a spring.

[0057] Further, an umbrella-shaped head is provided at one end of the valve core 23 opposite to the limiting circle 231. A neck ring groove is provided below the umbrella-shaped head. A through hole is provided on the water stop valve 22. The water stop valve 22 is installed on the valve core 23 through the umbrella-shaped head and is stuck at the neck ring groove to form a seal.

[0058] Further, four connecting legs 215 are provided on the outer side of the connecting ring 213. The connecting legs 215 are connected to the inner wall of the lower part 212. The connecting legs 215 divide the inner hole of the lower part 212 to form four flow channels 216. The four flow channels 216 cover most of the space, ensuring the smoothness of the water drainage.

[0059] Specifically, a thimble 151 and a water inlet hole 152 are provided inside the water inlet pipe 15. The thimble 151 is provided in the middle of the water inlet pipe 15, directly below the limiting circle 231 and is used in cooperation with the valve core 23. The water inlet hole 152 is provided outside the thimble 151. The humidifier 1 includes a lower cover 11, a humidification chamber 12, and an upper cover 13. The humidification chamber 12 is installed in the lower cover 11. The upper cover 13 is movably installed on the humidification chamber 12.

The water inlet pipe 15 is provided on the upper cover 13 and extends towards the position where the humidification chamber 12 is located.

[0060] Based on the above technical means: Under normal conditions, the water stop valve 22 of the adapter valve 2 seals the top of the lower part 212, playing a role in stopping water. When the adapter valve 2 and the water storage bottle 4 are installed on the humidifier 1 (water inlet pipe 15), the thimble 151 will lift the valve core 23 and the water stop valve 22, and the first reset member 24 is compressed, thereby opening the flow channel 216, enabling the water in the water storage bottle 4 to flow into the water inlet pipe 15 and start supplying water. By connecting the water storage bottle 4 and the humidifier 1 through the adapter valve 2, it is not necessary to install the humidifier 1 upside down, the operation is more convenient, and there will be no water overflow situation.

[0061] Furthermore, the diameter of the limiting circle 231 > the diameter of the connecting ring 213, which can limit the stroke of the valve core 23, prevent the valve core 23 from being pushed out of the connecting ring 213 by the thimble 151, and at the same time, the large-diameter limiting circle 231 also ensures that the thimble 151 can accurately push against the limiting circle 231, thereby lifting the water stop valve 22 and the valve core 23.

[0062] Specifically, a connecting portion 17 is provided on one side of the upper cover 13, and an assembly port 18 is formed on the same side of the lower cover 11 and the humidifying chamber 12 as the connecting portion 17. The connecting portion 17 is installed in the assembly port 18 and can be flipped in the assembly port 18.

[0063] Based on the above technical means: The upper cover 13 can be flipped under the action of the connecting portion 17 and the assembly port 18, so that the humidifying chamber 12 is opened, which is convenient for cleaning the humidifying chamber 12, ensuring the cleanliness inside the humidifying chamber 12 and not affecting the treatment effect of the ventilator.

[0064] Furthermore, two rotary lock grooves 153 are provided at the top of the water inlet pipe 15, the two rotary lock grooves 153 are arranged oppositely, and rotary locks 217 with the same number as the rotary lock grooves 153 are provided on the outer wall of the lower part 212. The rotary locks 217 are used in cooperation with the rotary lock grooves 153, and the rotary locks 217 can be screwed into the rotary lock grooves 153.

[0065] Based on the above technical means: The adapter valve 2 (lower part 212) is installed on the water inlet pipe 15 by a snap-fastening method. The snap-fastening connection method can ensure the stability of the two and is also convenient for disassembly.

[0066] Specifically, a water stop mechanism is also provided on the water inlet pipe 15. The water stop mechanism can control the water inflow. In this embodiment, the water stop mechanism is the air duct pipe 16. The air duct pipe 16 is arranged outside the water inlet pipe 15. The air duct pipe 16 and the water inlet pipe 15 form an inverted U-shaped pipe as an integral structure. The bottom of the air duct pipe 16 is flush with the bottom of the water inlet pipe 15, and the top of the air duct pipe 16 communicates with the water inlet pipe 15.

[0067] Based on the above technical means: when water floods over the bottom of the water inlet pipe 15 and the air duct pipe 16, the bottom of the water inlet pipe 15 and the air duct pipe 16 will be blocked, preventing water from entering the humidification chamber 12 again. When the water in the humidification chamber 12 is heated and volatilized, the water level drops, the water inlet pipe 15 and the air duct pipe 16 open, the air duct pipe 16 ventilates, and the water inlet pipe 15 refills with water, ensuring that the water level in the humidification chamber 12 remains stable and guaranteeing the heating efficiency of the heating plate 14.

[0068] A portable ventilator humidifying device further includes: a locking mechanism 3. One end of the main unit 5 is provided with a locking groove 51, and the locking groove 51 is used in cooperation with the locking mechanism 3.

Through the control module and the communication module (WIFI, Bluetooth, etc.), APP control can be adopted, making the humidifier more intelligent.

[0076] Embodiment 2:

[0077] Please refer specifically to Figure 13 , the rest of this embodiment is the same as that of Embodiment 1, except that: the water stop mechanism is the water stop float 6. The water stop float 6 is arranged in the water inlet pipe 15. The inside of the water stop float 6 is a hollow structure. Specifically, the diameter of the upper part 211 of the water stop float 6 < the diameter of the water inlet pipe 15 < the diameter of the lower part 212 of the water stop float 6. The upper part 211 of the water stop float 6 is sleeved in the water inlet pipe 15.

[0078] Based on the above technical means: When water enters the humidifying chamber 12, the water level in the humidifying chamber 12 will continuously rise, and the water-stop float 6 will also rise with the water level. When the water level rises to a certain height, the water-stop float 6 will block the water inlet pipe 15, and the water supply stops; the heating plate 14 will continuously heat the water in the humidifying chamber 12. During the heating process, the water will turn into water vapor, the water level will drop, the water-stop float 6 will drop with the water level, and the water inlet pipe 15 will reopen. At this time, the water supply can be normal again, ensuring the heating efficiency of the heating plate 14.

[0079] In some other feasible embodiments, heating plates 14 can also be added at the air inlet pipe 121 and the air outlet pipe 122 of the humidifying chamber 12, that is, the air path is heated.

[0080] The present invention is a portable ventilator humidifying device, and its implementation principle is as follows:

[0081] First, connect the host 5 and the humidifier 1 through the locking mechanism 3. The specific operation method is as follows: Press the pressing part 37, and the end of the first locking part 31 with the locking buckle 35 will move outward. The end of the second locking part 32 with the locking buckle 35 will move to the other outer side under the action of the gear 33, so that the distance between the two locking buckles 35 becomes larger, and the second reset part 34 is compressed, facilitating the locking buckle 35 to be placed into the locking groove 51 of the host 5; release the pressing part 37, and the second reset part 34 rebounds, driving the first locking part 31 to reset, so that the second locking part 32 also resets. The distance between the two locking buckles 35 becomes smaller, and the locking buckle 35 tightly buckles in the locking groove 51, completing the installation of the host 5 and the humidifier 1, and the host 5 conveys gas to the humidifier 1.

[0082] Then, connect the adapter valve 2 and the water storage bottle 4 through a threaded connection method, and then install the adapter valve 2 and the water storage bottle 4 on the humidifier 1 by a screwing method. When the adapter valve 2 and the water storage bottle 4 are installed in place, the thimble 151 contacts the limit circle 231, pushing up the water stop valve 22 and the valve core 23, opening the lower part 212 channel. The water in the water storage bottle 4 flows into the upper part 211 of the water inlet pipe 15 through the flow channel 216 and the water outlet, then enters the inside of the water inlet pipe 15 through the water inlet hole 152, and enters the humidifying chamber 12. Under the action of the heating plate 14, the water is heated into water vapor. Finally, the gas carries the water vapor and enters the mask together from the air outlet pipe 122, continuously providing moist and excellent gas for the user.

[0083] The foregoing has shown and described the basic principles, main features and advantages of the present invention.
