[0002] Nasal sprays are a common form of medication delivery, used to spray drugs into the nasal cavity to treat nasal-related conditions or provide other therapeutic effects. Traditional nasal sprays typically use a non-removable, one-piece nozzle design, meaning the nozzle and spray holder are integrated and cannot be replaced or cleaned.

[0003] However, this one-piece nozzle structure has some problems. First, manufacturing such a nozzle requires a significant amount of time and manpower to create the molds because the nozzle's structure is relatively complex. Second, once the nozzle is damaged or clogged, it cannot be replaced or cleaned, causing users to be unable to continue using the spray or requiring the purchase of a completely new spray holder, increasing usage costs and waste.

[0004] Therefore, a new type of nasal spray nozzle structure is needed to solve these problems. Utility Model Content

[0005] In order to solve the above-mentioned technical problems, this application provides a split-type nasal spray head that is easy to use and easy to replace.

[0006] A split-type nasal spray nozzle includes a spray base with a nozzle opening. A pressing sleeve is provided through the nozzle opening, and a spray head is sleeved inside the pressing sleeve. A spray channel for spraying into the nasal cavity is formed between the spray head and the pressing sleeve. The pressing sleeve can drive the spray head to move up and down relative to the nozzle opening to spray the spray from the spray head into the spray channel.

[0007] As described above, the split nasal spray nozzle has a snap-fit ​​groove inside the pressing sleeve, and a snap-fit ​​ring is provided on the periphery of the spray nozzle corresponding to the snap-fit ​​groove, which can be engaged with the snap-fit ​​groove so that the spray nozzle can be snapped onto the pressing sleeve.
