[specific embodiment]
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
As Fig. 1, Fig. 2 and shown in Figure 3, the anti-down wind apparatus that a kind of gas heater is used, comprise body 1, body 1 is coated with rotating shaft 2, be hinged with blinker 3 in the rotating shaft 2, body 1 air inlet one side is provided with interior lining panel 4, and interior lining panel 4 is provided with air vent 41, and blinker 3 covers on air vent 41 and forms unidirectional blocking.
Body 1 comprises upper tube body 11 and lower tube body 12, and interior lining panel 4 is located between upper tube body 11 and the lower tube body 12.As shown in Figure 1, upper tube body 11 and described lower tube body 12 are the ladder barrel that has bead, and described interior lining panel 4 is fixed between the bead of described upper tube body 11 and described lower tube body 12; As shown in Figure 4, upper tube body 11 and lower tube body 12 are the straight cylinder that has bead, and interior lining panel 4 is fixed between the bead of upper tube body 11 and lower tube body 12; As shown in Figure 5, the straight cylinder that upper tube body 11 and lower tube body 12 are, interior lining panel 4 outer rims are provided with the fillet 46 that turns over downwards, and fillet 46 is fixedlyed connected with lower tube body 12 inwalls, can upper tube body 11, lower tube body 12 and interior lining panel 4 be welded together by welding procedure; As shown in Figure 6, upper tube body 11 and lower tube body 12 are ladder barrel, and interior lining panel 4 outer rims are provided with the flange 47 that turns over downwards, and flange 47 is fixedlyed connected with lower tube body 12 inwalls, can upper tube body 11, lower tube body 12 and interior lining panel 4 be welded together by welding procedure.
