Description

Technical Field

[0001] The utility model relates to the technical field of gas wall-mounted boiler accessories, and particularly relates to an efficient smoke exhaust and ventilation system for a wall-mounted boiler. Background Technique

[0002] The gas wall-mounted heating boiler originated in Europe at the earliest and has a history of more than a hundred years. Now, due to the long development history, mature technology and good quality of wall-mounted boilers of European origin, they have become the favorites in the market. The full name of the "wall-mounted boiler" is: "gas wall-mounted heating boiler". It and the gas instantaneous water heater are both fast heating devices without a hot water storage device, but there are essential differences in structure. When using a gas wall-mounted boiler, a smoke exhaust pipe needs to be installed at its upper end to discharge the waste gas and soot generated inside. In the existing technology, after the smoke exhaust pipe is used, due to the high temperature of the pipe and the gas furnace, it needs to inhale air during the cooling process, and it is easy to inhale outdoor dust and sundries into the pipe. The sundries and dust may burn together with high temperature during internal combustion, causing use hazards. In addition, the flue gas discharged from the smoke exhaust pipe also contains a certain amount of heat, which is easy to cause waste of resources during cooling.

[0003] For example, the patent with the application number CN202120956395.8 discloses a smoke exhaust pipe with good heat dissipation performance for a gas wall-mounted boiler, including a pipe. A water tank is fixedly connected to the outside of the pipe. A heat conduction plate is fixedly connected inside the water tank. Through holes are formed in the heat conduction plate. An outlet pipe connection port is fixedly connected to the water tank. An inlet pipe connection port is fixedly connected to the water tank. A short pipe is fixedly connected inside the pipe. A hinge seat is fixedly connected to the upper end of the short pipe. A cover plate is hinged inside the hinge seat. By adding structures such as a water tank, a heat conduction plate and through holes to the outside of the pipe, the present utility model can dissipate heat from the pipe by injecting cold water into the water tank, and can discharge the cooled water into the gas wall-mounted boiler through the outlet pipe connection port for heating. After preheating the water through the pipe, a part of the gas consumption can be saved to achieve the energy-saving effect. However, when the flue gas is small, the device cannot lift the cover plate, and it is not convenient to open the cover plate from the outside when the smoke exhaust pipe needs to be cleaned, resulting in difficult cleaning.

[0004] In order to solve the above problems, this case came into being. Content of the Utility Model

[0020] The present utility model will be further elaborated in detail below with reference to the accompanying drawings and embodiments.

[0021] As Figures 1-4 shown: An efficient smoke exhaust and ventilation system for a wall-mounted boiler, including a water tank 1, a pipeline 2, and a water inlet pipe connection port 3. A support platform 4 is fixedly connected to the pipeline 2. A flap structure is provided on the support platform 4. The flap structure includes a displacement pipe 5, an inner pipe 6, and a cover plate 7. The inner pipe 6 is located inside the displacement pipe 5. The front half of the displacement pipe 5 is provided with an opening to expose the inner pipe 6 inside. The support platform 4 is fixedly connected to the inner pipe 6. When it is necessary to use the cover plate 7 to cover the pipe opening, first pull the pull ring 8 outwards so that it no longer engages in the chute 12, and then pull the displacement pipe 5 forward. At this time, the screw 9 moves along the chute 12. Since the chute 12 is in a "Z" shape, when the screw 9 reaches the end of the chute 12, the spring 10 contracts during the process, and the displacement pipe 5 and the cover plate 7 complete the flipping and cover the pipe opening, preventing dust and sundries from the outside from being sucked into the pipeline. When it is necessary to clean the inside of the pipeline, pull the pull ring 8 inwards until it engages at the end of the chute 12. At this time, the position of the screw 9 corresponds to the other end of the chute 12, the spring 10 expands, and the cover plate 7 flips upwards to expose the pipe opening, enabling the staff to conveniently clean the inside of the pipeline.

[0022] A fixed platform is provided on the displacement pipe 5. The pull ring 8 is slidably connected to the fixed platform. In the normal state, the pull ring 8 passes through the fixed platform and engages in the chute on the inner pipe 6, and when the cover plate 7 is in the flipped-up state, the pull ring 8 engages at the leftmost end of the chute 12. A screw 9 is also fixedly connected to the displacement pipe 5, and the end of the screw 9 passes through the displacement pipe 5 and is located at the left and right ends of the chute 12.

[0023] One end of a spring 10 is connected to the screw 9, and the other end of the spring 10 is fixedly connected to a fixed ring 11. The fixed ring 11 is fixedly connected to the support platform 4. When the pull ring 8 is pulled up, the spring 10 contracts, driving the displacement pipe 5 to move forward.

[0024] A cover plate 7 is fixedly connected to the displacement pipe 5. The cover plate 7 is fixedly connected to the side wall of the displacement pipe 5 at the opening of the displacement pipe 5. The support platform 4 and the inner pipe 6 are fixedly connected at the opening of the displacement pipe 5.

[0025] A chute 12 is provided on the inner pipe 6. The size of the pull ring 8 is smaller than the size of the chute 12, and the pull ring 8 is located inside the chute 12 when the cover plate 7 is in the flipped-up state in the normal state.

[0026] Based on the above embodiments as inspiration, through the above description, relevant staff can completely make various changes and modifications within the scope not deviating from the idea of this invention. The technical scope of this utility model is not limited to the content in the specification, and its protection scope must be determined according to the scope of the claims.
