Description

Technical Field

[0001] The utility model relates to the field of smoke exhaust components for wood-burning stoves, in particular to an automatic steering type smoke duct opening for wood-burning stoves. Background Art

[0002] As an important part of the wood-burning stove system, the wood-burning stove exhaust pipe is responsible for leading the smoke generated during the combustion process from the furnace to the outside, ensuring fresh indoor air while maintaining the efficiency of the fire; the end of the wood-burning stove exhaust pipe is provided with a flue port, and the flue port of a traditional wood-burning stove is usually fixed in direction and cannot be adjusted with changes in wind direction. In windy weather, especially when the wind direction changes frequently, the flue port may face headwind conditions, resulting in obstruction of smoke emission, which not only affects the combustion efficiency, but may also cause smoke to flow back into the room, polluting the air, posing a threat to user health, and seriously affecting the user experience.

[0019] like Figure 1 and Figure 5 As shown, an automatic steering type wood-fired stove flue port includes a flue pipe 1 and a smoke exhaust elbow 2. The top port of the flue pipe 1 is movably connected to the bottom smoke inlet of the smoke exhaust elbow 2. Connecting seats 3 are provided on both sides of the smoke exhaust elbow 2. A guide plate 4 is inserted into the connecting seat 3.

[0020] During normal use of the device, the smoke exhaust bend 2 can rotate freely around the axis of the flue pipe 1. When the external wind force is strong, the guide plates 4 can be plugged into both sides of the smoke exhaust bend 2. The external wind blows the guide plates 4 and provides thrust for them, thereby pushing the smoke exhaust bend 2 to rotate around the axis of the flue pipe 1 until the direction of the smoke exhaust port of the smoke exhaust bend 2 is 90° to the external wind force. The external thrust remains balanced and stops the smoke exhaust bend 2 from rotating, thereby preventing the smoke exhaust port from facing the direction of the wind and causing waste smoke to flow back into the furnace.

[0021] The preferred solution is Figure 2 and Figure 3As shown, an annular groove 5 is provided on the outer wall of the flue pipe 1, and the opening position of the groove 5 is close to the top port of the flue pipe 1. A roller 6 is installed in the groove 5, and the roller 6 is symmetrically arranged in a ring around the groove 5; a flexible clamp ring 7 is provided on the inner wall of the smoke exhaust elbow 2, and the flexible clamp ring 7 is close to the bottom smoke inlet of the smoke exhaust elbow 2. When the smoke exhaust elbow 2 is plugged into the flue pipe 1, the flexible clamp ring 7 is clamped in the groove 5 and contacts the roller 6;

[0022] When the smoke exhaust bend 2 needs to be installed, it is only necessary to insert the smoke exhaust bend 2 into the end of the flue pipe 1. During the insertion process, the flexible clamp 7 shrinks outward. When the smoke exhaust bend 2 continues to be inserted downward, the flexible clamp 7 moves to the slot 5. At this time, the flexible clamp 7 rebounds outward and is inserted into the slot 5. The flexible clamp 7 contacts the roller 6, which effectively reduces the friction when the smoke exhaust bend 2 rotates.

[0023] The preferred solution is Figure 4 As shown, a slot 9 is provided on the connecting seat 3, and a connecting rail 8 is provided on the side of the guide plate 4. The connecting seat 3 and the guide plate 4 are plugged and fixed to each other through the connecting rail 8 and the slot 9; when the external wind force is small, the guide plate 4 can be removed and the volume of the smoke exhaust port can be reduced. The guide plate 4 adopts a detachable installation method to facilitate subsequent replacement and maintenance.

[0024] The above embodiments are only preferred technical solutions of the utility model and should not be regarded as limitations of the utility model. Under the premise of non-conflict, the various technical features recorded in the utility model can be combined with each other. The protection scope of the utility model shall be the technical solution recorded in the claims, including the equivalent replacement solutions of the technical features in the technical solution recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the utility model.
