Among them, a water inlet pipe 25 is provided on the humidifier 2. The humidifier 2 is detachably connected to the main unit 1, the transfer valve 3 is detachably connected to the water inlet pipe 25, and a water storage bottle 4 is detachably connected to the transfer valve 3. The water storage bottle 4 and the transfer valve 3 can be connected by a threaded connection. Specifically, the water storage bottle 4 is a common threaded plastic bottle in the consumer market. The transfer valve 3 is provided with an internal thread adapted to the threaded plastic bottle. The water storage bottle 4 can be directly screwed onto the transfer valve 3 and then installed on the humidifier 2 through the transfer valve 3 to supply water to the ventilator.

[0059] Based on the above technical means: The water storage bottle 4 can be first connected to the adapter valve 3, and then the adapter valve 3 and the water storage bottle 4 are installed on the top of the humidifier 2. 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.

[0060] In this embodiment, the water storage bottle 4 has a standard mouth diameter (such as PCO 1810 / 1881), that is, the internal thread on the adapter valve 3 is adapted to the plastic bottle with a standard mouth diameter. For example, it can be adapted to the PCO1881 screw mouth of various mineral water bottles (such as Nongfu Spring, C'estbon, and Wahaha).

[0061] Please refer specifically to Figure 3 、 7 and 8, the humidifier 2 includes a lower cover 21, a humidification chamber 22, and an upper cover 23.

[0062] Based on the above technical means: The upper cover 23 can be flipped under the action of the connecting part 28 and the assembly port 29, so that the humidification chamber 22 is opened, which is convenient for cleaning the humidification chamber 22 and does not affect the treatment effect of the ventilator.

[0063] Please refer specifically to Figure 3 、 4 and 6, the adapter valve 3 includes a connector 31, a water stop valve 32, a valve core 33, and a first reset member 34. The connector 31 is a hollow structure and is composed of an upper part 311 and a lower part 312 which are of an integral structure and communicate with each other. An internal thread is arranged on the inner wall of the upper part 311 and is adapted to the screw mouth of the water storage bottle 4. A connecting ring 313 is arranged inside the lower part 312 of the connector 31, and two water outlet ports 314 are arranged at the bottom of the lower part 312 of the connector 31.

Through the control module and the communication module (such as WIFI, Bluetooth, etc.), it can be controlled by an APP, making the humidifier 2 more intelligent.

[0086] Embodiment 2:

[0087] Please refer specifically to Figure 13 , the rest of this embodiment is the same as that of Embodiment 1. The difference is that: the water stop mechanism is the water stop float 6. The water stop float 6 is arranged in the intake pipe 25. The inside of the water stop float 6 is a hollow structure. Specifically, the diameter of the upper part of the water stop float 6 < the diameter of the intake pipe 25 < the diameter of the lower part of the water stop float 6. The upper part of the water stop float 6 is sleeved in the intake pipe 25.

[0088] Based on the above technical means: when water enters the humidification chamber 22, the water level in the humidification chamber 22 will continue to 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 intake pipe 25 and the water supply stops; the heating plate 24 will continuously heat the water in the humidification chamber 22. During the heating process, the water will turn into water vapor, the water level drops, the water stop float 6 will drop with the water level, and the intake pipe 25 will be reopened, and at this time, the water supply can be normal again, ensuring the heating efficiency of the heating plate 24.

[0089] In some other feasible embodiments, heating plates 24 may also be added at the air inlet pipe 221 and the air outlet pipe 222 of the humidifying chamber 22, that is, heating the air path.

[0090] The present invention is a ventilator adapted to a common plastic bottle, and its implementation principle is as follows:

[0091] First, connect the main unit 1 and the humidifier 2 through the locking mechanism 5. The specific operation method is as follows: Press the pressing part 57, and the end of the first locking part 51 with the locking buckle 55 will move outward. The end of the second locking part 52 with the locking buckle 55 will move to the other outer side under the action of the gear 53, so that the distance between the two locking buckles 55 becomes larger, and the second reset part 54 is compressed, facilitating the locking buckle 55 to be placed into the locking groove 11 of the main unit 1; Release the pressing part 57, and the second reset part 54 rebounds, driving the first locking part 51 to reset, so that the second locking part 52 also resets, and the distance between the two locking buckles 55 becomes smaller, and the locking buckle 55 tightly fastens in the locking groove 11, completing the installation of the main unit 1 and the humidifier 2. The fan 13 in the main unit 1 works to draw air along the air inlet duct 14 into the fan 13, and then transports it to the air inlet pipe 221 through the air outlet duct 15, enters the humidifying chamber 22 through the air inlet pipe 221, combines with the water vapor in the humidifying chamber 22, and finally the air mixed with water vapor flows out from the air outlet pipe 222 for the user to use.

[0092] Then, connect the adapter valve 3 and the water storage bottle 4 through a threaded connection method, and then install the adapter valve 3 and the water storage bottle 4 on the humidifier 2 by a screwing method. When the adapter valve 3 and the water storage bottle 4 are installed in place, the ejector pin 251 contacts the limit circle 331, pushing up the water stop valve 32 and the valve core 33, opening the lower part 312 channel. The water in the water storage bottle 4 flows into the upper part 311 of the water inlet pipe 25 through the flow channel 316 and the water outlet 314, then enters the inside of the water inlet pipe 25 through the water inlet hole 252, and enters the humidifying chamber 22. Under the action of the heating plate 24, the water is heated into water vapor, and finally the gas carries the water vapor and enters the mask from the air outlet pipe 222 together, continuously providing the user with moist and excellent gas.

[0093] When the water level rises to a certain height, the water inlet pipe 25 is blocked. After the water in the humidifying chamber 22 is consumed, the water level drops, and the water inlet pipe 25 is reopened to continue the water supply, so that the water level in the humidifying chamber 22 is always stable, ensuring the heating efficiency of the heating plate 24.

[0094] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will also have various changes and improvements, and these changes and improvements fall within the scope of the present invention claimed. The scope of the present invention claimed is defined by the appended claims and their equivalents.
