Description

Technical Field

[0001] The present invention relates to the technical field of fire escape tools, in particular to a quick self-rescue and escape mask. Background Art

[0002] With the improvement of people's living standards, the increase in luxurious homes and furniture, and the continuous expansion of high-rise residential populations, the demand for fire prevention and firefighting is becoming increasingly stringent. In particular, the heavy smoke and flames that cause fires pose the greatest threat to human life. Therefore, in the event of an emergency, quick escape from dense smoke is extremely important. Currently, emergency self-priming masks (activated carbon filter cartridges) use dual-channel air inlet and outlet channels, which are complex in structure. In sudden fires, especially in dense smoke, the time from opening to wearing can exceed one minute, making it difficult to escape quickly in sudden disasters. Therefore, there is an urgent need to design a simple, fast, and effective self-rescue mask that can cover the mouth and nose in the dense smoke of an emergency, allowing escape within three minutes, and highlighting the concept that time is life.

The lower cover and the upper cover are sealed and clamped together. The wet inner cover and the dry outer cover are built into a sealed cavity formed by the lower cover and the upper cover. A liquid storage box is provided at the bottom of the lower cover. The wet inner cover is placed in the liquid storage box. The wet inner cover is arched upward in an arc shape. A saturated liquid-absorbing cotton ball is arranged between the liquid storage box and the upwardly arched wet inner cover, so that the liquid-absorbing cotton ball is in close contact with the wet inner cover to generate an overflow cycle, thereby ensuring that the wet inner cover is long-term moistened. The wet inner cover is clamped to the dry outer cover, and the dry outer cover is arranged above the wet inner cover.

[0005] Preferably, the bottom of the absorbent cotton ball is immersed in the low-lying area in the center of the liquid storage box, the liquid storage box is provided with a sodium benzoate compound liquid, and the top of the saturated absorbent cotton ball soaked in the sodium benzoate compound liquid is against the wet inner cover.

[0006] Preferably, the wet inner cover includes an inner cover crepe, an inner cover net support and a silicone sealing ring. The inner cover crepe is provided in two layers, the inner cover net support is provided between the inner and outer layers of the inner cover crepe, and the inner and outer layers of the inner cover crepe are jointly covered with a silicone sealing ring.

[0007] Preferably, the dry outer cover includes an outer cover crepe, an outer cover net support, a frame and a hand-grabbing mask. The outer cover crepe is provided with two inner and outer layers, and an outer cover net support is attached to the inner side of each outer cover crepe. The inner and outer cover crepes form a bag-shaped air chamber through the corresponding outer cover net support.

[0008] Preferably, the inner and outer covering crepes are jointly covered with a frame, and a hand-grabbing mask is provided outside the outer covering crepe.

[0009] Preferably, punching holes are provided around the circumference of the silicone sealing ring, and buckles are provided on the frame body corresponding to the punching holes, and the buckles are inserted into the corresponding punching holes.

[0010] Preferably, the dry outer mask is further provided with a neck strap, both ends of the neck strap are respectively fixed on the frame, and the neck strap is arranged on the outside of the hand-grabbing mask.

[0011] Preferably, the dry outer cover is also connected to goggles, and the goggles are fixed by a goggles bracket, and the goggles bracket is connected to the frame.

[0012] Preferably, the lower cover is provided with an annular positioning convex ring around its circumference, and the upper cover is provided with a fastener corresponding to the positioning convex ring. The two fasteners are symmetrically arranged, and the fasteners and the positioning convex ring are fastened to each other. The positioning convex ring is provided with a sealing groove opening upward, the sealing ring is built into the sealing groove, and the bottom of the upper cover is inserted into the sealing groove.

[0013] Preferably, a handle is provided on the top of the upper cover.

[0014] The beneficial effects of the present invention are: The upper cover and the lower cover are connected by snaps. When escaping, pry out any one of the two fasteners on the upper cover to quickly open the upper cover, then take out the wet inner mask and dry outer mask combination that are snapped together, hold the mask in your hand to cover your mouth and nose, put the neck strap back behind the ears, and complete the wearing process, which greatly shortens the wearing time. It can be opened to cover the mouth and nose within five seconds to achieve escape, especially in thick smoke, to achieve the goal of escape within three minutes. The elderly and the blind can also use it conveniently and quickly, fully embodying the concept that time is life. BRIEF DESCRIPTION OF THE DRAWINGS
