[0022] Embodiment 1:

[0023] Combined with Figures 1 to 3 A limited self-rebound mask comprises a mask body 1, both sides of the mask body 1 are fixedly connected with ear hanging ropes 2, and the middle part of the ear hanging ropes 2 is provided with a tension adjustment mechanism;

[0024] The tension adjustment mechanism includes an ear hook 3, which is C-shaped and is a hollow tube structure. A limited self-rebound knob 4 is provided in the middle of the ear hook 3, and an ear hook drawstring 5 is wound around the limited self-rebound knob 4. Both ends of the ear hook drawstring 5 extend out of the ear hook 3 and are connected to the ear hook rope through a buckle 6;

[0025] The limit self-rebound knob 4 includes a main body 4.1, which is a disc-shaped structure with a central axis 4.2 arranged therein, a tension spring 4.3 wound around the central axis 4.2, the tension spring 4.3 being a micro tension spring, two tension springs 4.3 being wound around the central axis 4.2 in reverse symmetry, the outer edge of the tension spring 4.3 being connected to an ear hook drawstring 5, two ear hook drawstrings 5 ​​being wound around the central axis 4.2 in reverse symmetry within the main body 4.1, a friction limit button 4.4 for locking and positioning being arranged outside the main body 4.1, two friction limit buttons 4.4 being arranged front and back.

[0026] In the specific implementation of this embodiment, the ear hook 3 is made of medical silicone material with strong skin-friendliness, and is ergonomically designed to match the human ear.

[0027] In the specific implementation of this embodiment, the ear hook drawstring 5 includes a rope core and a rope loop. The rope loop is arranged on the outer ring of the rope core. The ear hook drawstring 5 needs to contact the facial skin, so it is necessary to select high-tech fibers with good skin-friendliness to make the rope loop, and build in a high-strength flexible PE material rope core to ensure that its resistance meets the strength requirements of different scenarios.

[0028] In the specific implementation of this embodiment, the buckle 6 is a press-type buckle, and the disconnected mask ear hanging rope can be inserted and pressed to lock the high-strength ear hanging rope 5 with the mask's own ear hanging rope to form a new ear rope structure. The buckle is made of hard plastic or light alloy. If light alloy is used, a layer of flexible material needs to be coated on its surface to ensure that there is no discomfort when it comes into contact with the human body.

[0029] During the implementation of this embodiment, the friction limit button is released, and under a certain pulling force, the high-strength ear hook drawstring around the central axis can be pulled outward to a certain length; when the external force is less than the tensioning force of the built-in spring, the ear hook drawstring retracts inward; when the friction limit button is locked, the ear hook drawstring is fixed at a certain length, thereby realizing the free adjustment of the mask ear hook rope.

[0030] The ear hook adopts an ergonomic structure, increases the contact surface with the ear root, and uses silicone material with minimal skin irritation, which greatly reduces the obstruction of blood circulation in the ear caused by the thin ear hook rope, thereby causing pain behind the ear. At the same time, the silicone ear hook will not produce obvious pressure on the contact part of the ear, which can basically eliminate the discomfort of the ear and cheek contact part with the rope.

[0031] The utility model can be used alone or in pairs.

[0032] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
