Theupright column 31 is used as a fixed foundation, theupright column 31 is in a square tube shape, and one side of thelower shell 112 close to theshell 11 is provided with asleeve seat 1123 for the insertion of theupright column 31.

Referring to fig. 6 and 11, aright angle tube 32 is secured to the end of thepost 31 distal from thecannula hub 1123. The right-angle pipe 32 includes afirst ventilation section 321 parallel to the rotation axis of thelid 12 and asecond ventilation section 322 perpendicular to thefirst ventilation section 321, and thesecond ventilation section 322 extends in a direction away from the rotation connection position of thelid 12 and thehousing 11. The reserved joint 33 is arranged at one end of thefirst ventilation section 321 far away from thesecond ventilation section 322, and thefirst ventilation section 321 is inserted and fixed in the reserved joint 33. The corrugated joint 34 is arranged at one end of thesecond vent section 322 far away from thefirst vent section 321, and thesecond vent section 322 is inserted in the corrugated joint 34.

Referring to fig. 6 and 12, thevent passage 211 includes afirst passage 2111 coaxially disposed with thesecond vent section 322 and asecond passage 2112 communicating with an end of thefirst passage 2111 remote from thefirst vent section 321 and disposed in a vertical direction. Thesecond channel 2112 is communicated with the inner space of thehumidification box 2, the corrugated joint 34 is abutted against the side wall of one end of thefirst channel 2111, which is far away from thesecond channel 2112, and thebox body 21 extrudes and contracts the corrugated joint 34 when being fixed, so that the joint of thesecond ventilation section 322 and thebox body 21 is not easy to leak gas.

The implementation principle of the humidifier for the breathing machine in the embodiment of the application is as follows: in use, thefastener 5 is rotated to disengage theengagement block 53 from theengagement groove 1114. Then, theflip cover 12 is rotated to slide therotating slider 121 in therotating slide channel 1131, thereby rotating theflip cover 12 to open. When theflip 12 rotates, thestopper 122 is driven to rotate, and at this time, thestep part 1113 enters thestopper groove 1221 under the guidance of thewedge 1222, so that theflip 12 can keep the state of being opened by rotation. And, at this time, theair outlet component 4 is rotated by theflip cover 12, so that the sealingsoft sleeve 6 is separated from thebox cover 22. Then thehumidification box 2 is drawn out from theshell body 11, and theguide block 223 slides along theguide beam 1115, so that thehumidification box 2 is not easy to shake in the drawing process.

After thehumidification box 2 is drawn out, thebox cover 22 is opened, then a proper amount of clean water is added into thebox body 21, and thebox cover 22 is fixed with thebox body 21 again. Then thehumidification box 2 is pushed into theshell body 11, after thehumidification box 2 is pushed in, theguide block 223 is matched with theguide beam 1115 to form a limit position, and thelower lapping block 224 is matched with theupper lapping block 1117 to form a limit position. And the sidewall at thevent passage 211 of thehumidification case 2 compresses the bellows joint 34 such that thevent assembly 3 is in communication with thevent passage 211. Then, theflip cover 12 is pressed to slide thestep part 1113 out of the limitinggroove 1221 under the action of the extrudingwedge 1223, so that theflip cover 12 covers the opening of thehousing 11, and theflip cover 12 is fixed on thehousing 11 again by thesnap 5. And at the moment, thesoft sealing sleeve 6 is abutted against thehumidifying box 2, theturnover cover 12 tightly presses and fixes thehumidifying box 2 in theshell body 11 through thesoft sealing sleeve 6, and meanwhile, thesoft sealing sleeve 6 also plays a role in sealing. Clean air enters thehumidification box 2 from theair vent assembly 3, the air is humidified due to the absorption of evaporated water vapor, and the humidified air can be breathed by a user through theair outlet assembly 4.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
