The feeding bottle 42 is coaxially and fixedly arranged on the supporting circular plate 41, a piston cavity 421 is formed in the feeding bottle 42, and a spiral rib 423 is formed on the periphery of one end of the feeding bottle 42 away from the supporting circular plate 41. The screw rib 423 is screwed into the screwing groove to fix the feeding bottle 42 to the helmet 10, and the two overturning contact plates 43 are rotatably mounted on the supporting circular plate 41, and the two overturning contact plates 43 are respectively positioned on two opposite sides of the feeding bottle 42. The top surfaces of the turning contact plates 43 are formed with recessed surfaces 431, and the tops of the two turning contact plates 43 are respectively inserted into the two slits 15, so that the recessed surfaces 431 of the two turning contact plates 43 are both positioned in the wearing cavity 11. By providing two turning contact plates 43, the arc cover plate 16 can be prevented from being turned outwards at will, and when milk feeding is required, milk powder liquid can be injected into the piston cavity 421 of the milk bottle 42 to feed milk through the milk nozzle 18 before or after atomization treatment, so that the emotion of an infant is calmed. When the helmet 10 is not required to be worn, the helmet 10 can be removed from the head of the infant, the support disk 41 can be supported on the table, and the nursing bottle assembly 40 can be used for supporting the helmet 10 on the table. When it is desired to remove the feeding bottle 42, the feeding bottle assembly 40 is removed from the arced face mask 16 by forcibly flipping the two flip contact plates 43 outwardly and rotating the feeding bottle 42. The two flipping contact plates 43 are then flipped to a position of parallel abutment with the support circular plate 41.
