发明名称 Structure of draining mechanism for soft nose protrusion type diving mask
摘要 The present invention is to offer an improved structure of draining mechanism for soft nose protrusion type diving mask, which essentially comprises a valve flap seat with a plurality of through holes, is directly and integrally jointed at the bottom of a nose protrusion body of a soft liner frame when moulding the said frame of the diving mask and provided with an one-way valve flap; based on the integral structure of valve flap seat and nose protrusion body, when operating "balancing pressure" to tightly pinch the nose protrusion body, no gap will be formed between the valve flap seat and the nose protrusion body to effectively prevent infiltration water; and a bent flow-guiding device moulded integrally with and beneath the nose protrusion body and extended to the two sides of diving mask can drain and guide flow so as to prevent the exhausted bubbles from affecting the diver's visibility.
