The utility model discloses a device is used for otolaryngology one kind of nasal cavity humidifier, include: breathing mask, pipe, liquid storage tank and atomizer etc. The shape of breathing mask is compatible with the shape of nose and mouth, and the breathing mask is connected with the pipe, and the one end of pipe is connected with the liquid storage tank away from breathing mask, and the liquid storage tank is connected with the atomizer between pipe. The utility model discloses a device is provided with breathing mask, pipe and spray head, and the breathing mask is divided into nose cavity and mouth cavity, and two spray heads are respectively inserted into two nasal vestibules of user, reduce the risk of causing physical damage to the mucosa in the depth of nasal cavity, improve the comfort of user, still be provided with sealing strip, and the sealing strip is close to the middle part of user, so that the sealing strip divides the nose cavity and mouth cavity, avoid the gas of user mouth exhaling being inhaled into nasal cavity again, guarantee the breathing quality of user and the humidifying effect of this humidifier, reduce the risk of respiratory tract infection.

The present application provides a spray assembly and a nasal spray apparatus. The spray assembly comprises a spray head and a vortex portion accommodated in the spray head. A spray hole is arranged at the far end of the spray head. The vortex portion comprises a vortex cavity in communication with the spray hole and a vortex groove in communication with the vortex cavity. The vortex groove comprises a first flow-guiding surface and a second flow-guiding surface that are arranged opposite to each other. The second flow-guiding surface is tangent to a cavity wall of the vortex cavity. The included angle α between the first flow-guiding surface and the second flow-guiding surface is 14-30°. The diameter of the vortex cavity is 0.5-2.0 mm. In the spray assembly of the present application, arranging the vortex portion in the spray head enables the drug, when flowing through the vortex portion, to form a vortex and to be pressurized and accelerated, and limiting structural parameters of the vortex portion enables the sprayed drug to achieve a predetermined spray angle and spray particle size, thereby avoiding a situation where the spray angle or particle size is so large that the drug is excessively deposited on the wall of the nasal vestibular cavity, avoiding a situation where the spray angle is so small that a mist cannot be formed, and avoiding a situation where the spray particle size is so small that the drug enters the lungs, which raises safety concerns.
