<p>A nasal inhalation device comprises an elastic clip (5) and main body boxes (1) fixed on the elastic clip (5). Each main body box (1) includes a bottom box (2), and a domed hemispherical cover (3) which is coupled with and covers on the bottom box (2). A connection member is provided between the bottom box (2) and the cover (3). The cover (3) is provided with ventholes (6), and the bottom box (2) is provided with air-permeable holes (7). The bottom of the bottom box (2) is a domed spherical surface. The ratio of the height h1 and the length h2 of the main body box (1) is as follows: h1:h2=1:1.2~1:1.5. The ratio of the radius R of bottom spherical surface of the bottom box (2) and the length h3 of the main body box (1) is as follows: R:h3=1:1.5~4. The ratio of the height h4 of the cover (3) and the height h3 of the bottom box (2) is as follows: h4:h3=1:1~2.</p> |
