[0020] Embodiment

[0021] Combined with Figure 1-5 As shown, a convenient-to-use improved fire door includes a door frame 1. A first spraying mechanism 3 is provided on the door frame 1. Through the setting of the first spraying mechanism 3, a water curtain can be formed on both sides of the door body 2 in case of a fire, preventing poisonous gas and thick smoke from entering the fire escape passage through the gap between the door body 2 and the door frame 1. At the same time, the door body 2 can be watered to cool down, facilitating personnel to push the door body 2 to escape during a fire. The door body 2 is hingedly connected inside the door frame 1. A second spraying mechanism 4 is provided inside the door body 2. Through the setting of the second spraying mechanism 4, the door handle 202 can be sprayed in case of a fire, preventing the door handle 202 from being unable to be used due to heat.

[0022] Combined with Figure 2-3 As shown, the first spraying mechanism 3 includes a U-shaped protective cover 306 symmetrically arranged on both sides of the door frame 1. Through the setting of the protective cover 306, the water guide pipe 301 can be protected, improving the service life of the water guide pipe 301. An installation groove 307 is opened inside the protective cover 306. A water guide pipe 301 with one side connected to the outer side wall of the door frame 1 is provided inside the installation groove 307. A number of first high-pressure nozzles 302 are arranged at equal distances on the inner end face of the water guide pipe 301. The two water guide pipes 301 are connected by a connecting water pipe 303. One end of the connecting water pipe 303 is connected to an external water tank 305, and a first water pump 304 is provided on the connecting water pipe 303.

[0023] Among them, spraying ports 308 corresponding to the first high-pressure nozzles 302 one by one are opened on the inner end face of the protective cover 306. The size of the spraying ports 308 is larger than that of the first high-pressure nozzles 302, thus ensuring the spraying effect of the first high-pressure nozzles 302. A protective net 309 made of stainless steel is provided on the spraying ports 308. Through the setting of the protective net 309 on the spraying ports 308, the first high-pressure nozzles 302 can be prevented from being damaged by knocking, thus affecting the fire-fighting water spraying work of the first high-pressure nozzles 302.

[0024] like Figure 4 The door body 2 shown in the figure has accommodating grooves 201 on both side end faces of the door body 2, and a door handle 202 is provided on the outer surface of the door body 2 in the accommodating groove 201. A temperature sensor 5, a smoke sensor 6 and a controller 7 are respectively provided on one side end face of the door body 2, and the temperature sensor 5, the smoke sensor 6 and the controller 7 are electrically connected.

[0025] like Figure 5 The second spray mechanism 4 shown in the figure comprises a plurality of evenly distributed second high-pressure nozzles 401 arranged on the inner side wall of the accommodating groove 201 at the top of the door handle 202. The second high-pressure nozzles 401 can spray the door handle 202 when a fire occurs, thereby ensuring that the door body 2 can be pushed normally by the door handle 202 during fire escape. A water supply pipe 404 is provided in the door body 2. One end of the water supply pipe 404 is connected to a built-in water tank 406 located in the door body 2. The other end of the water supply pipe 404 is provided with a high-pressure water pipe 403 connected to the second high-pressure nozzle 401, and a second water pump 405 is provided on the water supply pipe 404.

[0026] The built-in water tank 406 is provided with a water inlet pipe 402 with one end extending to the outside of the door body 2 . The water inlet pipe 402 is provided to facilitate the staff to add water to the built-in water tank 406 .

[0027] The working principle of the utility model is:

[0028] When a fire occurs, the smoke sensor 6 or the temperature sensor 5 senses smoke or high temperature and transmits the information to the controller 7. The controller 7 simultaneously controls the first water pump 304 and the second water pump 405 to be turned on. The first water pump 304 transports the water in the external water tank 305 to the water pipe 301 through the connecting water pipe 303, and sprays the water on both sides of the door body 2 through the first high-pressure nozzle 302 to form a water curtain, so as to prevent poisonous gas and thick smoke from entering the fire passage through the gap between the door body 2 and the door frame 1, and to prevent the fire scene from being damaged. The smoke can be blocked and the door body 2 can be cooled by spraying water, which is convenient for people to push the door body 2 to escape during fire. At the same time, the second water pump 405 transports the water in the built-in water tank 406 to the high-pressure water pipe 403 through the water supply pipe 404, and sprays the water onto the door handle 202 through the second high-pressure nozzle 401 to cool the door handle 202 to prevent the door handle 202 from being unusable due to heat, thereby ensuring that the door body 2 can be pushed normally by the door handle 202 during fire escape.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
