WIPO Patent Application WO/2022/126623
Kind Code:
A1
Abstract:
A spray nozzle structure of a nasal spray bottle, comprising a spray head (51), a connecting plate (52), and a pressing part (53); the spray head (51) and the pressing part (53) are respectively disposed on two opposite surfaces of the connecting plate (52); the spray head (51) passes through a housing (60) which applies a downforce, and can extend into the nasal cavity for spraying; the connecting plate (52) is connected to the inner surface of the housing (60) to form a connection basis for a spray nozzle body (50); the connecting plate (52) is provided with a connecting part (521), a first tube opening (522), and an offset channel (523); the connecting part (521) is adapted to be connected to the inner surface of the housing (60); the first tube opening (522) is communicated with an upper suction tube (31) of a suction member (30); one end of the offset channel (523) is communicated with the first tube opening (522), and the other end of the offset channel (523) is communicated with a spray pipe (510) which passes through the spray head (51); the pressing part (53) is adapted to abut against a compression part (32) of the suction member (30) to transfer the downforce of the housing (60) to the compression part (32), forming a suction action of the suction member (30). The spray nozzle structure changes a spraying path by providing the offset channel (523), shortens the distance between two spray nozzles, and fits the two nasal cavities of the human body, thus supporting simultaneous administration or cleaning of the two nasal cavities.
