Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 to 6, the CPAP device 1 provided by the present invention includes a body 10, a blower (not shown) accommodated in the body, and a humidifier including a humidifier tub 20 and a heating unit 11, wherein the humidifier tub 20 is detachably mounted to the body.

The body 10 is provided with a switch 13, and the switch 13 is used to turn on and off the humidifier tub 20.

The CPAP device is further provided with a guide for guiding the humidifier tub to be removed from or attached to the CPAP device.

An airway adapter 24 is also provided on the CPAP device, and the airway adapter 24 connects the blower and humidifier.

The humidifier container 20 is provided with an air inlet 23 and an air outlet 22, an air passage connector 24 is connected with the air inlet 23, and the air outlet 22 is connected with the air guide pipe of the mask.

The air duct joint 24 has openings 241 at both ends, a rubber sleeve 242 is mounted at one end, and a groove 243 is further arranged on the air duct joint 24.

The body 10 is provided with a chamber portion for accommodating the humidifier tub 20, slide rails 12 are provided at both sides of the chamber portion, and an elastic unit (not shown) is further provided at the chamber portion.

The humidifier tub 20 is also provided with a guide rail 25, the guide rail 25 being used to guide the mounting of the humidifier tub in cooperation with the slide rail 12 when the humidifier tub 20 is installed in the CPAP device.

The switch 13 includes a button 130, a cylinder 131, a cap 132, a push rod 133, and an elastic member 135. An elastic member 135 is installed between the cylinder 131 and the cap 132, and a catch 136 is provided on the push rod 133. The catch 136 abuts a groove 243 on the airway adapter 24. The shape of the catch 136 is the same as the groove 243.

To remove the humidifier tub 20 from the CPAP device 1, the humidifier tub is removed by: when the button 130 is pressed, the push rod 133 moves toward the airway connector 24, and the airway connector 24 is lifted upward and separated from the humidifier tub 20 by the latch 136, so that the humidifier tub 20 is ejected by the elastic unit.

The method of loading the humidifier tub 20 into the CPAP device is: the guide rail 25 of the humidifier tub 20 is abutted against the slide rail 12 of the CPAP apparatus 1; pushing the humidifier tub 20 inward; the front end of the humidifier tub 20 abuts against the air duct joint 24, and under the action of thrust, the air duct joint 24 moves upward first against the action force of the elastic element 135, and then moves downward under the action of the elastic element 135 after the rubber sleeve 242 of the air duct joint 24 enters the air inlet 23 of the humidifier tub 20 to seal the air inlet 23 and lock the humidifier tub 20.

As shown in fig. 7, the humidifier tub 20 is further provided with a backflow prevention mechanism, specifically, a first partition wall 27 and a second partition wall 28 are provided near the air inlet 23 and the air outlet 22. The first partition wall 27 is disposed opposite the gas inlet 23 and extends parallel to the bottom surface of the humidifier tub 20. The second partition wall 28 extends inwardly along the air outlet. Because the first and second partition walls 27 and 28 are provided, the water 26 does not flow out from the inlet port 23 or the outlet port 22 when the humidifier tub 20 is deflected.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
