[0027] The following combines Figures 1 to 2 the embodiments shown to describe the technical solution of the present utility model:
[0028] The present utility model provides a fire-fighting smoke exhaust water gun, including: a water gun head 1; a detachable and bendable steel pipe 2, one end of which is detachably connected to the water gun head 1, and the detachable and bendable steel pipe 2 is communicated with the water gun head 1 through a transfer interface 101; a hanging tooth 3, fixedly arranged on the outer side wall of the detachable and bendable steel pipe 2.
[0029] It can be understood that the present utility model provides a fire-fighting smoke exhaust water gun. The entire smoke exhaust water gun is fixed on the window sill by using the hanging tooth 3 cylinder. By pressurizing the water outlet, a low pressure will be formed indoors. By using positive and negative pressures, the purpose of extracting the smoke in the fire field can be achieved, so as to achieve the purpose of reducing the indoor smoke temperature and increasing the indoor visibility, greatly improving the safety factor during the work of firefighters and reducing the risk of indoor interior attack.
[0030] In the present utility model, the water gun head 1 is detachably connected to one end of the detachable and bendable steel pipe 2. The water gun head 1 is a commonly used spray water gun head in fire fighting. When using the device provided by the present utility model, the water gun head 1 is opened and maintained in a blooming state, and by pressurizing the water outlet, it is convenient to form a low pressure indoors, so as to extract the smoke in the fire field by using positive and negative pressures.
[0031] The inside of the detachable bendable steel pipe 2 is a hollow structure. One end of the detachable bendable steel pipe 2 is connected to the water gun head 1, and the other end of the detachable bendable steel pipe 2 is connected to the water inlet pipe. The water from the water inlet pipe is sprayed out through the water gun head 1 via the detachable bendable steel pipe 2. The function of the detachable bendable steel pipe 2 is to spray the water from the outside through the indoor area and then through the water gun head 1 to the outside. The water passing through the indoor area takes away a part of the heat in the indoor area, and in a closed space, the pressure can be reduced. A part of the detachable bendable steel pipe 2 is arranged indoors, and a part is arranged outdoors. The steel pipe connected to the water inlet pipe and the water gun head 1 is arranged outside the window, and the other bent steel pipes are arranged inside the window. Therefore, when setting up this device, two holes facilitating the passing of the bendable steel pipe need to be opened in advance on the glass window of the closed space. After passing through the holes on the glass window and installing the detachable bendable steel pipe 2, the water can be led to the position of the water gun head 1 through the detachable bendable steel pipe 2. By pressurizing the water outlet, a low pressure can be formed indoors, and using positive and negative pressures, the smoke in the fire scene can be pumped out.
[0032] The hanging teeth 3 are fixedly arranged on the outer side wall of the detachable bendable steel pipe 2, and the hanging teeth 3 are fixedly arranged at the position where the detachable bendable steel pipe 2 contacts the glass window. The main function of the hanging teeth 3 is to fix the detachable bendable steel pipe 2 on the glass window, facilitating the firefighters to hold and fix the smoke exhaust water gun provided by the present utility model. Since the hanging teeth 3 and the detachable bendable steel pipe 2 are fixedly connected, there must be certain unclosed parts and gaps when the through holes opened on the glass window catch the detachable bendable steel pipe 2 at the position of the hanging teeth 3. When water is passed and the water gun head 1 is started, a low pressure is formed indoors, and the smoke in the fire scene can be extracted through the unclosed parts and gaps. While reducing the temperature of the indoor smoke, the visibility indoors is improved. If the gap is small, the glass window can be slightly opened to facilitate the discharge of the indoor smoke.
[0033] When a fire breaks out in a closed space such as a civilian house or a residential building, the firefighters first open two through holes facilitating the passing of the detachable bendable steel pipe 2 at the corresponding positions on the glass window. At the same time, the glass window is clamped between the two hanging teeth 3 to facilitate fixing the position of the detachable bendable steel pipe 2. Then, the water gun head 1 is installed at the water outlet end of the detachable bendable steel pipe 2. After water is passed, the water flow passes through the indoor area and is sprayed out through the water gun head 1, taking away the heat in the indoor area and reducing the temperature of the indoor smoke. A low pressure is formed indoors, and using positive and negative pressures, the smoke in the fire scene is pumped out, improving the visibility indoors and reducing the risk of firefighters' indoor offensive operations.
[0034] Without the need for indoor offensive operations, the firefighters can conduct smoke exhaust outdoors, improving the safety factor. At the same time, it can cover the indoor offensive personnel to effectively fight the room fire and reduce the risk of indoor offensive operations.

[0043] In the utility model, a plurality of hanging teeth 3 are fixedly arranged on the outer side wall of the second horizontal pipe 203, and the plurality of hanging teeth 3 are located on the same horizontal line. When a through hole corresponding to the second horizontal pipe 203 is opened in the glass window, a hole through which the hanging teeth 3 can pass should also be opened. As long as the position of the hanging teeth 3 passing through the glass window is controlled so that the position of the hanging teeth 3 after being firmly connected to the second horizontal pipe 203 is not the same as the position of the hanging teeth 3 during installation, the purpose of fixing the position of the second cross bar can be achieved. The distance between two adjacent hanging teeth 3 is matched with the cross-sectional thickness of the glass window. The arrangement of a plurality of hanging teeth 3 facilitates the matching of the length of the second cross bar with the window sill, and is convenient for firefighters to hold the second vertical pipe 204 to fix the entire smoke exhaust water gun during subsequent water supply.
[0044] According to the fire fighting smoke exhaust water gun provided by the utility model: A valve 206 is fixedly arranged at one end of the second vertical pipe 204 away from the second horizontal pipe 203.
