A nasal spray with a detachable nozzle is designed. The nozzle can be inserted into the nasal cavity and connected to a connecting sleeve via a thread. A top cover connecting device is provided. The top cover assembly includes a part that can be connected to the connecting sleeve, a part that can be connected to the connecting sleeve, and a part that can be detached from the connecting sleeve and has a nozzle. A pressing component includes a gas pump that can introduce gas into the medicine bottle and is connected to the connecting sleeve, and a gas pump that can be detached from the connecting sleeve and pumps the medicine liquid out of the nozzle.
It enables flexible nozzle insertion and accurate liquid spraying, improving ease of operation and treatment effectiveness, reducing the frequency of pressing, and increasing efficiency.
