Abstract:
A nasal irrigation head (10), a bottle (40) and a nasal irrigator. The nasal irrigation head (10) comprises a flow guide head (11), an adjusting valve (12), and a sealing member (20) used for being connected to the bottle (40), wherein the flow guide head, the adjusting valve and the sealing member are sequentially connected; a first flow guide channel (21) is provided in the sealing member (20) in a penetrating manner, a second flow guide channel (121) is provided in the adjusting valve (12) in a penetrating manner, and the flow guide head (11) is provided with a third flow guide channel (111); the first flow guide channel (21), the second flow guide channel (121) and the third flow guide channel (111) are sequentially in communication with one another; the flow guide head (11) comprises a nozzle (112), an extension tube (113) and a flow guide tube (114) which are sequentially connected; and the flow guide tube (114) is connected to the adjusting valve (12), the extension tube (113) and the flow guide tube (114) are arranged in a bent manner, and the adjusting valve (12) and the flow guide tube (114) form a grip portion (30) for a human hand to hold. The nasal irrigation head (10) is lengthened to allow stable holding thereof in the human hand; and the lengthened nasal irrigation head (10) can provide a larger height drop, so as to achieve a larger hydraulic drop from the bottle (40) to the nozzle (112), and thus the hydraulic drop is increased, such that when there is not much residual liquid in the bottle (40), the sprayed liquid still has a sufficient flow speed.
