Technical Field

[0001] The utility model relates to the technical field of atomizing masks, in particular to an atomizing mask for children which is not easy to fall off. Background Art

[0002] Pediatrics is a comprehensive medical science that studies the physical and mental development, health care, and disease prevention and treatment of children. All health and hygiene issues related to children and adolescents fall within the scope of pediatrics. The subjects of treatment are in the growth and development period. The task of pediatrics is to continuously explore pediatric medical theories, reduce morbidity and mortality rates based on practice, enhance the physical fitness of children and adolescents, and improve the level of health care and disease prevention and treatment for children and adolescents.

[0003] Some existing atomizing breathing masks are put on the face of children, and two straps are placed on the outside of the child's brain. Since children have small heads, the straps are easy to slip off the head, which easily leads to waste of medicine and ineffective treatment. Therefore, a children's atomizing mask that is not easy to fall off is needed to solve the above problems. Utility Model Content

[0004] The utility model provides a children's atomizing mask which is not easy to fall off, aiming to solve the problem in the prior art that children's heads are small and easily move around, resulting in the mask falling off.

[0007] Preferably, the fixing block is rotatably mounted on the base.

[0008] Preferably, the headrest and the inner pillow are both made of elastic rubber, and the curvature of the headrest is greater than that of the inner pillow, and a layer of sponge pad is provided on the inner side of the inner pillow.

[0009] Preferably, a prismatic block is provided at the lower end of one side of the fixing rod mounting spring.

[0010] Preferably, ribs are provided on both sides of the spring seat.

[0011] Preferably, the mask can adjust its clamping degree by means of the engaging teeth on the strap.

[0012] The beneficial effects of the utility model are as follows: when in use, first press the button, lift the other end of the fixing rod, then pull the engaging teeth out of the lock opening, put on the mask, put on the headrest, and insert the engaging teeth into the lock opening. The headrest and the inner pillow are made of elastic materials and a sponge pad is provided on the inner pillow to reduce the clamping feeling of the strap when wearing. At the same time, the curvature of the inner pillow is smaller than that of the headrest, so it can be used for smaller heads. The engaging teeth can slide in the lock opening on the lock, thereby driving the adjustment of the strap to adjust the tightness of the mask. Because the headrest is larger, it can effectively prevent the strap from slipping when the child moves around. BRIEF DESCRIPTION OF THE DRAWINGS
