Abstract

The outlet side of a kind of backward-wind preventing device, the wind deflector including smoke exhaust pipe and down-draught-proof, wind deflector and smoke exhaust pipe is pivotally connected, and the end face of the outlet side of the smoke exhaust pipe and the axis of smoke exhaust pipe have acute angle, and the wind deflector is oval；When the axis of smoke exhaust pipe is parallel to the horizontal plane, the end face of outlet side and horizontal plane have acute angle, the upper end pivot joint of the long axis of the upper end and outlet side of the long axis of wind deflector；When the axis and horizontal plane of smoke exhaust pipe, the end face of outlet side and horizontal plane have acute angle, the lower end pivot joint of the long axis of the lower end and outlet side of the long axis of wind deflector.Due to using such structure, when smoke exhaust pipe has flue gas emission, the effect wind deflector automatic turning of air-flow, and leave the outlet side of smoke exhaust pipe；When smokeless, wind deflector is fastened with the outlet side of smoke exhaust pipe automatically；When external wind enters, make wind deflector with the outlet side of smoke exhaust pipe is closer is bonded, realize smoke-backflow-proof.

Description

A kind of backward-wind preventing device

Technical field

The utility model relates to a kind of gas heater or the air exhausting devices of burnt gas wall hanging furnace.

Background technique

Currently available technology, a kind of backward-wind preventing device, the wind deflector including smoke exhaust pipe and down-draught-proof, wind deflector and smoke exhaust pipe Outlet side pivot joint.There are problems to be: the outlet side poor sealing performance of wind deflector and smoke exhaust pipe.

Utility model content

The purpose of this utility model is: providing a kind of backward-wind preventing device, it has good seal performance, self-closed smoke exhaust pipe The characteristics of outlet side.

The utility model is realized in this way: a kind of backward-wind preventing device, the wind deflector including smoke exhaust pipe and down-draught-proof keep out the wind The pivot joint of the outlet side of plate and smoke exhaust pipe, is characterized in that the end face of the outlet side of the smoke exhaust pipe and the axis of smoke exhaust pipe There is acute angle, the wind deflector is oval；

When the axis of smoke exhaust pipe is parallel to the horizontal plane, the end face of outlet side and horizontal plane have acute angle, the length of wind deflector The upper end of the long axis of the upper end and outlet side of axis is pivotally connected；

When the axis and horizontal plane of smoke exhaust pipe, the end face of outlet side and horizontal plane have acute angle, the length of wind deflector The lower end of the long axis of the lower end and outlet side of axis is pivotally connected.

A kind of backward-wind preventing device, be characterized in that further include both ends open hurricane globe, the one of hurricane globe It closes up and is equipped with interface in end；

The outlet side of the smoke exhaust pipe is protruded into hurricane globe, and interface is fixedly connected with smoke exhaust pipe.

A kind of backward-wind preventing device, is characterized in that further include circular fixing plate, on circular fixing plate Equipped with fixed plate interface；

Smoke exhaust pipe passes through fixed plate interface, and fixed plate interface is fixedly connected with smoke exhaust pipe.

A kind of backward-wind preventing device is characterized in that the smoke exhaust pipe is equipped with annular protrusion, the fixation Plate interface and annular protrusion cooperate stop bit；The interface and circular fixing plate of the hurricane globe cooperate stop bit.

A kind of backward-wind preventing device of the utility model, due to using such structure, when smoke exhaust pipe has flue gas emission, air-flow Wind deflector automatic turning is acted on, and leaves the outlet side of smoke exhaust pipe；When smokeless, wind deflector automatically with the outlet of smoke exhaust pipe End fastens；When external wind enters, make wind deflector with the outlet side of smoke exhaust pipe is closer is bonded, realize smoke-backflow-proof.

Detailed description of the invention

Fig. 1 is the main view of the utility model.

Fig. 2 is the main view of the utility model smoke evacuation state.

Fig. 3 is the main view of the utility model down-draught-proof state.

Fig. 4 is the main view of second of use state of the utility model.

Specific embodiment

The utility model is further described with reference to the accompanying drawing.

As shown in Figure 1, a kind of backward-wind preventing device, the wind deflector 2 including smoke exhaust pipe 1 and down-draught-proof, wind deflector 2 and smoke exhaust pipe 1 outlet side pivot joint, the end face of the outlet side of the smoke exhaust pipe 1 and the axis of smoke exhaust pipe 1 have acute angle, in other words, smoke evacuation The end face of pipe outlet side is oval；The wind deflector 2 is oval；

As shown in Figure 1 and Figure 2, when the axis of smoke exhaust pipe 1 is parallel to the horizontal plane, the end face of outlet side and horizontal plane have acute angle Angle α, the upper end pivot joint of the long axis of the outlet side of the upper end and smoke exhaust pipe 1 of the long axis of wind deflector 2.

As further improvement of the utility model: further including the hurricane globe 3 of both ends open, one end of hurricane globe 3 is closed up And it is equipped with interface 31；

The outlet side of the smoke exhaust pipe 1 is protruded into hurricane globe 3, and the interface 31 of hurricane globe 3 is fixedly connected with smoke exhaust pipe 1.

It is further improved as the utility model: further including circular fixing plate 4, circular fixing plate 4 is equipped with solid Fixed board interface 41；

The smoke exhaust pipe 1 is equipped with annular protrusion, and smoke exhaust pipe 1 passes through fixed plate interface 41 and is fixed together, Gu Fixed board interface 41 and annular protrusion cooperate stop bit；The interface 31 and circular fixing plate 4 of the hurricane globe 3 cooperate stop bit.

Fig. 1 is stationary state, and when smoke exhaust pipe has air-flow flowing, stream pressure rotates counterclockwise wind deflector 2, such as Fig. 2 institute Show；In smoke evacuation state；Using finishing；After airless pressure, wind deflector 2 under gravity, rotates clockwise automatically, Wind deflector 2 is bonded with the outlet side of smoke exhaust pipe 1, as shown in Figure 3；Under Fig. 3 state, external wind makes to keep off after the entrance of hurricane globe 3 Aerofoil 2 and the outlet side of smoke exhaust pipe fit closely, and prevent air outside the external world from entering smoke exhaust pipe 1.

Such as Fig. 4 institute method, the axis and horizontal plane of smoke exhaust pipe 1, the end face of outlet side and horizontal plane have acute angle β, The lower end of the long axis of the lower end and 1 outlet side of smoke exhaust pipe of the long axis of wind deflector 2 is pivotally connected；When smoke evacuation, wind deflector 2 is rotated counterclockwise. Smoke evacuation finishes, and wind deflector 2 turns clockwise automatically, the outlet side automatic buckling of wind deflector and smoke exhaust pipe 1.

Above-described is only the preferred embodiments of the utility model.It should be pointed out that for the common of this field For technical staff, in the case where not departing from the utility model principle, it can also make several improvements and modification, this is also considered as The protection scope of the utility model.
