Therefore, through the arrangement of the abutting column 6b, when breathing in, the floating hollow tube 8 is actuated towards the direction of the breathing mask 1, due to the blocking of the thimble 6a, the abutting column 6b can be contacted with the needle head of the thimble 6a, the abutting column 6b is prevented from moving along with the floating hollow tube 8, therefore, the buffer spring 6c can be pulled away from the normal state, and the arrangement of the micro pressure sensor 6d, the more the floating hollow tube 8 is actuated towards the direction of the breathing mask 1, the larger the pressure resisted by the thimble 6a of the micro pressure sensor 6d is, the larger the pressure is, the magnitude of the pressure sensed by the micro pressure sensor 6d is, so as to judge the breathing degree of the child, the larger the pressure is, the better the breathing recovery is, on the contrary, the smaller the pressure is, the breathing is weak, when the child exhales, the floating hollow tube 8 can be actuated towards the anti-off end 7b, and the buffer spring 6c returns to the normal state, the pressing column 6b shields the hollow opening of the floating hollow tube 8, so that the medicament cannot enter the breathing mask 1 through the floating hollow tube 8 during expiration.

This application has realized the effectual recovery to children's respiratory track through adjustable medicine supply device 5 according to children's breathing degree to the regulation of dose medicine supply, has improved recovery efficiency and effect.

The above examples, which are intended to represent only one or more embodiments of the present invention, are described in greater detail and with greater particularity, and are not to be construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
