Technical Field

[0001] The utility model relates to the technical field of masks, in particular to a mask with adjustable ear straps. Background Art

[0002] A mask is a sanitary product, generally refers to a device worn on the mouth and nose to filter the air entering the mouth and nose, so as to block harmful gases, odors, and droplets from entering and exiting the wearer's mouth and nose. It is made of gauze or paper. The mask has a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent, wearing a mask is very effective when working in an environment polluted by dust. At present, most of the masks circulating on the market have elastic ear straps, so as to be as suitable as possible for people of different age groups. However, wearing elastic ear straps for a long time will cause discomfort in the ears.

[0003] The traditional mask design may cause some users to encounter the problem of ear straps being too tight or too loose when wearing them, which not only affects the wearing comfort, but may also reduce the protective effect of the mask.

[0004] Therefore, it is particularly important to design a mask with adjustable ear straps to change the above-mentioned technical defects and improve overall practicality. Utility Model Content

In the utility model, a mask with adjustable ear strap tightness is provided, and the structure of an adjusting shell, a pressure rod, a pressing plate, a compression spring, a accommodating frame, a sliding block, a sliding block, and an extrusion sleeve is utilized. The pressing plate on the pressing and adjusting shell is pressed to press the pressure rod downward, and the extrusion block at the bottom thereof pushes the sliding block to move, and the first sliding block of the sliding block is displaced along the sliding groove, and the arc-shaped fixing rod lifts the upper extrusion sleeve to separate it from the lower extrusion sleeve. At this time, the adjusting shell is moved to adjust the tightness of the ear strap to suit different face shapes. After the pressing plate is released, the compression spring and the tension spring are reset, and the upper and lower extrusion sleeves are combined to fix the position of the ear strap. A soft pad is provided on the outside of the adjusting shell to increase the comfort. After the adjustment is completed, it can be worn normally. If it needs to be adjusted again, the above operation is repeated, which solves the problem that some users may encounter the problem of too tight or too loose ear straps when wearing the mask due to the traditional mask design, which not only affects the wearing comfort, but also may reduce the protective effect of the mask.
