The invention provides a breathable mask. The breathable mask includes a body and a breathing tube in fluid communication with the interior of the body. The interior of the body is divided into an eye bag and a mouth-nose bag, and the sum of the inner volume of the eye bag and the inner volume of the mouth-nose bag is not larger than 500 milliliters; and if the user wears the mask, the sum of the residual internal volume of the eye bags and the residual internal volume of the mouth-nose bag is not more than 400 milliliters. According to the snorkeling mask, by reducing the inner volume of the mask, a user can naturally and completely spit or nearly completely spit under the normal breathing tidal volume, transient vacuum in the mask is formed, external fresh air can actively and easily enter the mask when a snorkeling person inhales the mask next time, and the snorkeling person can breathe more safely and smoothly.

    本发明提出一种可呼吸面罩。可呼吸面罩包含一本体及一呼吸管,与本体内部呈流体连通。本体内部区分为一眼袋及一口鼻袋,其中眼袋的内容积与口鼻袋内容积的总和,不大于500毫升;若使用者配戴此面罩后,眼袋所剩余的内容积,与该口鼻袋所剩余的内容积,其总和不大于400毫升。通过缩小面罩内容积,可让使用者在其正常呼吸潮气量下,可以自然将气完全吐光或接近完全吐光,形成面罩内暂态真空,让外部新鲜空气得以在浮潜者下一次吸气时,主动且轻易地进入面罩内,使浮潜者的呼吸更安全顺畅。
