[0001] The utility model relates to the field of gas wall-mounted boilers, in particular to a smoke exhaust pipe for gas wall-mounted boilers. Background Art

[0002] The gas wall-mounted boiler is a device with powerful home central heating function. It can meet the heating needs of multiple rooms, allowing each room to set a comfortable temperature as needed. It can also decide to turn off the heating in a certain room as needed, and can provide a large flow of constant temperature sanitary hot water for use in home bathing, kitchen and other places.

[0003] The gas wall-mounted boiler needs to discharge the flue gas when in use, so a smoke exhaust pipe is needed. However, the smoke exhaust pipe of the gas wall-mounted boiler in the existing technical solution has a poor smoke exhaust effect and does not have a filtering function for the exhausted smoke, which causes the exhausted smoke to pollute the surrounding environment. Utility Model Content

[0004] The embodiment of the present application provides a smoke exhaust pipe for a gas wall-mounted boiler, which solves the technical problem that the smoke exhaust pipe of the gas wall-mounted boiler in the prior art solution has a poor smoke exhaust effect and does not have a filtering function for the exhausted smoke, which causes the exhausted smoke to pollute the surrounding environment.

[0005] The technical solution adopted in the embodiment of the present application is as follows:

[0006] A smoke exhaust pipe for a gas wall-mounted boiler comprises a corrugated pipe installed at the smoke exhaust port of the gas wall-mounted boiler, a smoke exhaust pipe mechanism for exhausting smoke and an activated carbon filter device for filtering smoke; the corrugated pipe is connected to the smoke inlet of the smoke exhaust pipe mechanism; the activated carbon filter device is arranged in the smoke exhaust pipe mechanism.

[0007] A further technical solution is: the smoke exhaust pipe mechanism includes an output pipe, a delivery pipe connected to the corrugated pipe, an annular stopper for limiting the movement of the activated carbon filter device, and a filter top cover for filtering smoke; the output pipe is connected to the delivery pipe; the annular stopper is arranged on the inner side of the output pipe; the filter top cover is installed at the smoke exhaust port of the output pipe; and the filter top cover is provided with a plurality of filter holes arranged in a circular array.

[0008] A further technical solution is: the activated carbon filtering device includes an annular block, an annular placement box for placing activated carbon, and a connecting rod arranged on the annular block; an annular groove adapted to the annular block is opened at the smoke exhaust port of the conveying pipe; the annular block is embedded in the annular groove; the connecting rod is connected to the annular placement box; a plurality of circular perforations arranged in a circular array are opened on both sides of the annular placement box; a rectangular opening for taking and placing activated carbon is opened at the top of the annular placement box.

[0009] A further technical solution is: the smoke exhaust pipe mechanism also includes an annular rubber pad; the annular rubber pad is arranged around the conveying pipe.

[0010] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0011] 1. Due to the use of bellows, exhaust pipe mechanism and activated carbon filter device, when the gas wall-mounted boiler needs to exhaust smoke, the smoke discharged from the exhaust port of the gas wall-mounted boiler will be transported to the exhaust pipe mechanism through the bellows. Since the activated carbon filter device is set in the exhaust pipe mechanism, the smoke entering the exhaust pipe mechanism will pass through the activated carbon filter device. At this time, the activated carbon in the activated carbon filter device will filter the harmful substances in the smoke, and the filtered smoke will be discharged through the exhaust port of the exhaust pipe mechanism. At this time, the smoke input into the environment will be filtered by the activated carbon filter device, which will reduce the pollution to the surrounding environment.

[0012] 2. Due to the arrangement of the output pipe, the delivery pipe, the annular block and the filter top cover, when the output pipe is installed on the delivery pipe, the annular block on the output pipe will abut against the activated carbon filter device, thereby fixing the activated carbon filter device. Since the filter top cover is provided with a plurality of filter holes arranged in a circular array, the smoke filtered by the activated carbon filter device can be filtered again through the filter holes provided in the filter top cover. Since the activated carbon filter device can be detachably installed in the delivery pipe, and the delivery pipe is threadedly connected to the output pipe, it is convenient for the user to disassemble the activated carbon filter device in the exhaust pipe mechanism for cleaning.

[0013] 3. Due to the use of the annular block, annular placement box, circular perforations, connecting rods and annular slots, by placing activated carbon in the annular placement box, harmful impurities contained in the flue gas can be adsorbed. Since the annular block is detachably plugged into the annular slot, when the user removes the output pipe and the delivery pipe, it is convenient for the user to take out the annular placement box and then clean the annular placement box. Through the setting of the rectangular opening, when the user takes out the annular placement box, it is convenient for the user to replace the activated carbon in the annular placement box.

[0014] 4. Due to the provision of the annular rubber pad, when the user installs the exhaust pipe for the gas wall-mounted boiler at the wall opening, the annular rubber pad is in contact with the wall opening, thereby protecting the exhaust pipe for the gas wall-mounted boiler from wear and tear.

DETAILED DESCRIPTION

[0019] The embodiment of the present application provides a smoke exhaust pipe for a gas wall-mounted boiler, which solves the technical problem that the smoke exhaust pipe of the gas wall-mounted boiler in the prior art solution has a poor smoke exhaust effect and does not have a filtering function for the exhausted smoke, which causes the exhausted smoke to pollute the surrounding environment.

[0020] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0021] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] A smoke exhaust pipe for a gas wall-mounted boiler, such as Figure 1 and Figure 2 As shown, it includes a bellows 1 installed at the smoke outlet of a gas wall-mounted boiler, a smoke exhaust pipe mechanism 2 for exhausting smoke, and an activated carbon filter device 3 for filtering smoke. The bellows 1 is connected to the smoke inlet of the smoke exhaust pipe mechanism 2. The activated carbon filter device 3 is arranged in the smoke exhaust pipe mechanism 2.

[0023] The smoke inlet at the left end of the bellows 1 is fixedly installed at the smoke outlet of the gas wall-mounted boiler. The smoke outlet at the right end of the bellows 1 is threadedly connected to the smoke inlet at the left end of the smoke exhaust pipe mechanism 2. Since the bellows 1 itself is made of soft elastic material, it is convenient for users to adjust the angle of the bellows 1. The activated carbon filter device 3 is detachably installed in the smoke exhaust pipe mechanism 2.

[0024] Through the arrangement of the bellows 1, the smoke exhaust pipe mechanism 2 and the activated carbon filter device 3, when the gas wall-mounted boiler needs to exhaust smoke, the smoke exhausted from the smoke exhaust port of the gas wall-mounted boiler will be transported to the smoke exhaust pipe mechanism 2 through the bellows 1. Since the activated carbon filter device 3 is arranged in the smoke exhaust pipe mechanism 2, the smoke entering the smoke exhaust pipe mechanism 2 will pass through the activated carbon filter device 3. At this time, the activated carbon in the activated carbon filter device 3 will filter the harmful substances in the smoke, and the filtered smoke will be discharged through the smoke exhaust port of the smoke exhaust pipe mechanism 2. At this time, the smoke input into the environment will be filtered by the activated carbon filter device 3, thereby reducing the pollution to the surrounding environment.

[0025] like Figure 1 As shown, the smoke exhaust pipe mechanism 2 includes an output pipe 21, a delivery pipe 22 connected to the corrugated pipe 1, an annular stopper 23 for limiting the movement of the activated carbon filter device 3, and a filter top cover 24 for filtering smoke. The output pipe 21 is connected to the delivery pipe 22. The annular stopper 23 is arranged on the inner side of the output pipe 21. The filter top cover 24 is installed at the smoke exhaust port of the output pipe 21. The filter top cover 24 is provided with a plurality of filter holes 241 arranged in a circular array.

[0026] The smoke outlet at the right end of the output pipe 21 is preferably a conical structure. The activated carbon filter device 3 is detachably installed in the delivery pipe 22. The smoke inlet at the left end of the delivery pipe 22 is threadedly connected to the smoke outlet at the right end of the corrugated pipe 1. The smoke inlet at the left end of the output pipe 21 is threadedly connected to the smoke outlet at the right end of the delivery pipe 22. The annular stopper 23 is fixedly connected to the inner side of the output pipe 21. The filter top cover 24 is threadedly connected to the smoke outlet at the right end of the output pipe 21.

[0027] Through the arrangement of the output pipe 21, the delivery pipe 22, the annular stopper 23 and the filter top cover 24, when the output pipe 21 is installed on the delivery pipe 22, the annular stopper 23 on the output pipe 21 will abut against the activated carbon filter device 3, thereby being able to fix the activated carbon filter device 3. Since the filter top cover 24 is provided with a plurality of filter holes 241 arranged in a circular array, the smoke filtered by the activated carbon filter device 3 can be filtered again through the filter holes 241 provided in the filter top cover 24. Since the activated carbon filter device 3 is detachably installed in the delivery pipe 22, and the delivery pipe 22 is threadedly connected to the output pipe 21, it is convenient for the user to disassemble the activated carbon filter device 3 in the smoke exhaust pipe mechanism 2 for cleaning.

[0028] like Figure 3As shown, the activated carbon filter device 3 includes an annular block 31, an annular placement box 32 for placing activated carbon, and a connecting rod 33 arranged on the annular block 31. An annular groove 221 adapted to the annular block 31 is provided at the smoke outlet of the delivery pipe 22. The annular block 31 is embedded in the annular groove 221. The connecting rod 33 is connected to the annular placement box 32. A plurality of circular perforations 321 arranged in a circular array are provided on both sides of the annular placement box 32. A rectangular opening 322 for taking in and placing activated carbon is provided at the top of the annular placement box 32.

[0029] A plurality of connecting rods 33 arranged in a circular array are fixedly provided on the annular clamping block 31. Each group of connecting rods 33 is fixedly connected to the annular placement box 32. When the annular clamping block 31 is inserted into the annular clamping groove 221 provided at the smoke outlet of the delivery pipe 22, and then threadedly connected to the delivery pipe 22 through the output pipe 21, the annular stopper 23 will abut against the annular clamping block 31, thereby fixing the position of the annular placement box 32 in the delivery pipe 22. The annular placement box 32 is used to place activated carbon. When the smoke passes through the annular placement box 32, the smoke will contact the activated carbon in the annular placement box 32, thereby filtering out harmful impurities in the smoke.

[0030] By setting the annular block 31, the annular placement box 32, the circular perforation 321, the connecting rod 33 and the annular slot 221, by placing activated carbon in the annular placement box 32, harmful impurities contained in the flue gas can be adsorbed. Since the annular block 31 is detachably plugged into the annular slot 221, when the user removes the output pipe 21 and the delivery pipe 22, it is convenient for the user to take out the annular placement box 32 and then clean the annular placement box 32. By setting the rectangular opening 322, when the user takes out the annular placement box 32, it is convenient for the user to replace the activated carbon in the annular placement box 32.

[0031] like Figure 1 As shown, the smoke exhaust pipe mechanism 2 further includes an annular rubber pad 25. The annular rubber pad 25 is arranged around the delivery pipe 22.

[0032] The annular rubber pad 25 is fixedly connected to the outside of the delivery pipe 22 .

[0033] By providing the annular rubber pad 25, when the user installs the exhaust pipe for the gas wall-mounted boiler in the wall opening, the annular rubber pad 25 is in contact with the wall opening, thereby protecting the exhaust pipe for the gas wall-mounted boiler from wear.
