[0004] In the prior art, spraying liquid is mainly achieved by pressing the nozzle. The liquid spraying port is mostly arranged at the top of the nozzle. Different from other parts of the spray, the nasal spray process needs to be stable to prevent the nozzle from shaking and damaging the inner wall of the nasal cavity. Ordinary nozzles mostly achieve spraying liquid by pressing the top of the nozzle. When a patient sprays the nasal cavity by himself, first, the spray bottle needs to be kept vertically placed to ensure that the spray can be sucked. This causes that the bottle body can only be held by the position of the palm, and the top of the nozzle is pressed by the thumb. When pressing the nozzle, a certain force is required. The way of holding the bottle body with the palm and pressing the top of the nozzle with the thumb will first cause slipping due to the flow and residue on the outer wall of the bottle body. Secondly, pressing the top of the nozzle with the thumb will form an interference between the nose and the spray port, which is not convenient for the patient to use by himself.

[0005] Therefore, we propose a nasal sprayer. Content of the Utility Model
