[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] like Figures 1-3 As shown, this application discloses an anti-fall-off nasal oxygen tube, including a hollow shell 1, an air supply pipe 2 installed at the air inlet end of the hollow shell 1, a connecting pipe 3 installed at the air inlet end of the air supply pipe 2, two air outlets at the upper end of the hollow shell 1 respectively installed with an inhalation assembly, a fixing assembly installed at the front end of the hollow shell 1 and near both sides, the inhalation assembly includes a telescopic tube 4, a semi-circular tube body 5 installed at the upper end of the telescopic tube 4, a fixing layer 6 provided on the outer side of the semi-circular tube body 5, a limit plate 7 installed on the outer side of the semi-circular tube body 5 and at the bottom end of the fixing layer 6, and a plurality of spring plates 8 installed on the inner side of the semi-circular tube body 5.

[0022] The semi-circular tube 5 is inserted into the user's nostril. The spring plate 8 provides elastic support for the semi-circular tube 5, causing the semi-circular tube 5 to move the fixing layer 6 to fit inside the user's nostril. The limiting plate 7 limits the length of the semi-circular tube 5 inserted into the nostril. By setting the telescopic tube 4 to be softly connected to the air outlet of the hollow shell 1, the semi-circular tube 5 can be prevented from falling off when the user's lips move.

[0023] like Figure 1 , 2 As shown in Figure 4, the fixing component includes two straps 10. Connecting straps 11 are installed between the two straps 10 and on the outer sides of both ends for connection. Connecting components are installed on the straps 10 and on the other end. The hollow shell 1 is fixed by setting the straps 10 to be tied to the user's head. By setting connecting straps 11 between the two straps 10 and on the outer sides of both ends, the straps 10 can be prevented from falling off when tied to the head. The connecting components make it easy to put on and take off.

[0024] like Figure 1 , 2As shown in Figure 4, the connecting assembly includes a housing 14 and a second magnet 20. A mounting plate 15 is installed in a mounting cavity on one side of the housing 14. A locking block 16 is installed on one side of the mounting plate 15, penetrating the partition between the two mounting cavities within the housing 14. A first magnet 18 is installed on the other side of the mounting plate 15. A spring 19 is installed between the other side of the mounting plate 15 and the mounting cavity. Limiting blocks 17 are installed between the front and rear ends of the mounting plate 15 and the mounting cavity. A plug 13 is inserted into a mounting cavity on one side of the housing 14. An adjusting buckle 12 is installed at the rear end of the plug 13. A trapezoidal block is located on the front side of the other side of the plug 13. The rear end of 16 is designed to be inclined. The adjusting buckle 12 can adjust the length of the strap 10. When the insert 13 is inserted into the mounting cavity on one side of the housing 14, it contacts the locking block 16 and squeezes the locking block 16 to move to the other side. After the trapezoidal block on the insert 13 passes the locking block 16, it drives the mounting plate 15 and the locking block 16 to reset under the action of the spring 19, thus fixing the insert 13. The limiting blocks 17 set at the front and rear ends of the mounting plate 15 can limit the mounting plate 15. When the second magnet 20 is attached to the other side of the housing 14, the second magnet 20 attracts the first magnet 18 to drive the locking block 16 away from the insert 13, thus releasing the fixing of the insert 13.

[0025] like Figure 2 As shown, a self-adhesive label 9 is installed on the rear flat surface of the hollow shell 1. A silicone paper is provided at the rear end of the self-adhesive label 9. The self-adhesive label 9 can be used to attach the hollow shell 1 to the user's upper lip for reinforcement, and the silicone paper can be used to protect the self-adhesive label 9.

[0026] like Figure 3 As shown, the fixing layer 6 is provided with multiple inclined protrusions. The interior of the inclined protrusions is hollow. By providing multiple hollow inclined protrusions on the fixing layer 6, the fixing effect of the semi-circular tube 5 can be improved by contacting the inner wall of the nose.
