Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

FIG. 1 is a schematic view of a preferred embodiment of the smoke ventilator of the present invention;

as shown in fig. 1, the embodiment provides a smoke exhaust fire protection device, which includes a housing 1, and an air inlet and an air outlet disposed at two ends of the housing 1, wherein the front surface of the housing 1 is in a horn shape, and the air inlet is disposed at the front surface. The inside fixedly connected with connecting rod 2 of casing 1, the middle part fixedly connected with motor 3 of connecting rod 2 are provided with dust cover 8 on the motor 3, fixedly connected with flabellum 31 on motor 3's the rotor, and flabellum 31 is towards the air intake. When the smoke exhauster works, the motor 3 drives the fan blades 31 to rotate, so that smoke is exhausted from the air inlet to the air outlet, and rescue and relief work of firemen is facilitated. The dust cover 8 can protect the motor 3, and the service life of the motor 3 is prolonged.

As shown in fig. 1, a fan protection net 7 is arranged on the air outlet, and the fan protection net 7 is fixedly connected with the outer side of the casing 1 through screws. The fan protective screening 7 can play a certain protective role to the smoke exhaust fan, and meanwhile, the fan protective screening 7 can be detached and is convenient to clean.

Fig. 1 is an alternative front view of a small fan 41 of the present invention;

optionally, the outer circumference of the air outlet of the housing 1 is fixedly connected with a plurality of shaping hoses 4, and the end of each shaping hose 4 is fixedly connected with a small fan 41. The position of small-size fan 41 can be adjusted at will in the setting of design hose 4, and then can adjust small-size fan 41's air intake and air outlet to can select to make small-size fan 41's air outlet be towards the air intake of casing 1 or towards the flue gas. If towards the air outlet of casing 1, then can further accelerate the flue gas and take out, if towards the flue gas, then can blow away the flue gas, make things convenient for the rescue personnel to see the inside condition of flue gas clearly to convenient rescue saves rescue time.

Fig. 2 is an alternative cross-sectional view of the inventive blade 52;

optionally, a reinforcing rod 5 is disposed in the housing 1, the reinforcing rod 5 is located below the fan blades 31, a plurality of rotating shafts 51 are rotatably disposed on the reinforcing rod 5, and each rotating shaft 51 is fixedly connected with a blade 52. The reinforcing rod 5 is arranged to improve the strength of the shell 1, and the blades 52 are arranged to accelerate the exhaust of smoke from the interior of the shell 1.

Fig. 3 is an alternative top view of the spray device 6 of the present invention;

optionally, the spraying device 6 includes a ring pipe 61, a plurality of nozzles 62 and a water pump 63, the water pump 63 is fixed outside the housing 1, a water outlet of the water pump 63 is connected with the ring pipe 61, a water inlet of the water pump 63 is connected with an external water source, and the plurality of nozzles 62 are arranged along the circumference of the ring pipe 61. Preferably, shower nozzle 62 sets up to the toper, and water pump 63 works for in external water source flowed into annular pipe 61 from water pump 63's delivery port, then spout to being vaporific water smoke from each shower nozzle 62, make the coverage area bigger, make the coverage area of putting out a fire bigger, also conveniently discharge fume simultaneously, make the flue gas can not be very dense, make things convenient for the induced-draft fan to use, improve the fire extinguishing effect of discharging fume.

As shown in FIG. 1, during the spraying process of the spray heads 62, dust in the flue gas can block the spray heads 62, and in order to improve the effect of the spray heads 62, each spray head 62 is coated with a layer of filter cotton 64. The filter cotton 64 can filter the smoke, so that the smoke is not easy to block the spray head 62, and the spraying effect is improved.

In summary, when the smoke exhaust machine works, the motor 3 works to drive the fan blades 31 to rotate, so that the smoke is extracted from the air inlet and exhausted to the air outlet. The angle that design hose 4 can change small-size fan 41 for small-size fan 41 increases the effect of discharging fume towards the air intake of casing 1, perhaps makes small-size fan 41 towards the flue gas, blows off the flue gas, makes things convenient for the rescuer to see the condition of ignition inside clearly, improves small-size fan 41's suitability.
