[0023] The present application will be described in detail below in combination with the drawings and embodiments.

[0024] Embodiment: an oxygen mask, such as Figures 1-4As shown, it comprises a mask body 1, a headgear 2, a fixing plate 3, an ear-hanging part 4 and a connecting device. The headgear 2 is used to be worn on the head of a patient from top to bottom. In order to improve the wearing comfort of the headgear 2, a sponge pad is arranged on the inner surface of the headgear 2, and preferably a breathable layer is arranged on the outer surface of the sponge pad to avoid direct contact between the sponge pad and the head of the patient. The ear-hanging part 4 is fixed at both ends of the headgear 2 and is used to be clamped on both sides of the head of the patient. A notch 5 corresponding to the ear of the patient is arranged on the ear-hanging part 4, and the opening of the notch 5 is located on the side of the ear-hanging part 4 away from the headgear 2. When the ear-hanging part 4 is clamped on both sides of the head of the patient, the ear of the patient is located in the notch 5 to avoid being pressed. Similarly, a sponge pad is arranged on the inner surface of the ear-hanging part 4, and preferably a breathable layer is arranged on the outer surface of the sponge pad to avoid direct contact between the sponge pad and the head of the patient.

[0025] Preferably, the fixing plate 3 is fixed on the opposite sides of the mask body 1. In order to improve the wearing comfort of the patient, a silicone soft pad is arranged on the part of the mask body 1 used to contact the face of the patient. The connecting device is provided with two, and the two connecting devices are symmetrically arranged on the two ear-hanging parts 4. The connecting device comprises a pipe 62, a spring piece 63 and a fixing piece. One end of the pipe 62 is used to be detachably connected with the fixing plate 3, and the other end is used to be inserted into the outer surface of the fixing piece. A magnet piece 61 is fixed on the end of the pipe 62 away from the ear-hanging part 4. An iron piece is arranged on the side of the fixing plate 3 close to the face of the patient. The iron piece is magnetically connected with the magnet piece 61 to make the mask body 1 cover the mouth and nose of the patient.

[0026] Preferably, the spring piece 63 is fixed in the pipe 62 and is used to be tightly pressed between the inner surface of the pipe 62 and the outer surface of the fixing piece. The fixing piece is fixed on the ear-hanging part 4. Specifically, the fixing piece comprises a first conical column 641, a second conical column 642 and a cylindrical part 643 connected in sequence. The first conical column 641 and the second conical column 642 each comprise a large-diameter end and a small-diameter end. The small-diameter end of the first conical column 641 is fixed with the ear-hanging part 4, the large-diameter end of the first conical column 641 is fixed with the large-diameter end of the second conical column 642, and the small-diameter end of the second conical column 642 is fixed with one end of the cylindrical part 643. The taper of the first conical column 641 is smaller than the taper of the second conical column 642, the diameter of the large-diameter end of the first conical column 641 is the same as the diameter of the large-diameter end of the second conical column 642, and the spring piece 63 is used to be tightly pressed between the pipe 62 and the first conical column 641. The spring piece 63 is provided with a plurality of spring pieces 63, which are arranged in the pipe 62 at equal intervals along the circumferential direction of the pipe 62. Specifically, the spring piece 63 is provided with three. The two ends of the spring piece 63 are fixed on the inner wall of the pipe 62, the length direction of the spring piece 63 is the same as the length direction of the pipe 62, the spring piece 63 is arc-shaped and the outer arc surface is tightly pressed with the circumferential surface of the first conical column 641.

[0027] When wearing, first, the headgear 2 is worn, then the mask body 1 is held by hand, the mask body 1 is magnetically connected on the magnet sheet 61 through the fixed plate 3, so that the mask body 1 is connected with the cannula 62, then the cannula 62 is inserted into the cylindrical part 643 and continues to be inserted into the ear hanging part 4 direction, so that the elastic sheet 63 moves along the length direction of the first conical column 641, when the elastic sheet 63 moves along the length direction of the first conical column 641, the elastic sheet 63 first abuts against the second conical column 642, then abuts against the first conical column 641, finally always abuts against the circumferential surface of the first conical column 641, when the mask body 1 is adjusted to the appropriate position, that is, when the mask wearing is more comfortable, the hands can be relaxed, because the first conical column 641 has a certain taper, therefore, after the hands are relaxed, under the action of the elastic sheet 63, the cannula 62 always has the force of approaching the patient's face, therefore, has a certain self-adapting effect, not only will not cause the mask body 1 to extrude the patient's face, but also has a better connecting effect, flexible and convenient to use.

[0028] The above only is the preferred embodiment of the present application, the protection scope of the present application is not only limited to the above-mentioned examples, all technical solutions belonging to the idea of the present application are the protection scope of the present application. It should be pointed out that, for the ordinary skilled in the art, under the premise of not departing from the principle of the present application, some improvements and modifications, these improvements and modifications should also be regarded as the protection scope of the present application.
