Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in embodiment 1 provided in fig. 1-4, an air filtering device is used for a machine requiring exhaust emission, such as a gas water heater and a gas wall-hanging stove, and the air filtering device includes a flange 1, a filter cotton 2 and a smoke tube 3, the flange is a connection way, and is used for connecting the machine and the smoke tube 3 on the gas water heater or the gas wall-hanging stove, generally located right above the machine, the flange 1 of the embodiment is installed at the connection part of the smoke tube 3 and the machine, and the filter cotton 2 is placed inside the flange 1;
the flange 1 is of a circular ring structure and comprises two semicircular sub-bodies 11, and the sub-bodies 11 are fixedly connected to form the flange 1.
The device achieves the purpose of convenient disassembly by arranging the flange into the two semicircular annular flanges, and the filter cotton 2 is arranged inside the flange to realize the function of air filtration, so that an air filtration device is not additionally arranged, and the cost of the machine and the maintenance cost of a user are reduced.
In this embodiment, the filter cotton 2 is in a semicircular shape, a semicircular clamping groove 111 for clamping the filter cotton 2 is formed in the inner side of the semicircular ring of the sub-body 11, and the filter cotton 2 can be placed in the clamping groove 111 to filter air; the clamping groove 111 is matched with the filter cotton 2, so that the filter cotton 2 is firmly arranged in the clamping groove 111, the filter cotton 2 is ensured to be accurate, reliable and convenient to disassemble and assemble, and the clamping groove 111 and the sub-body 11 are of an integrated structure.
As shown in fig. 2 and fig. 3, in this embodiment, at least two buckles 112 for connecting the flange 1 and the machine are arranged at the bottom of the sub-body 11, and the minimum size in the buckles 112 is slightly smaller than the sheet metal thickness of the machine, so as to ensure that the flange 1 and the machine are firmly fixed.
The outer side of the sub-body 11 is provided with a screw hole 113 for installing a screw for locking the flange 1 on a machine, and only a common cross screwdriver is needed for dismounting operation, so that the operation steps are reduced, and the dismounting cost is saved.
In this embodiment, the upper plane of the connection portion between the sub-body 11 and the clamping groove 111 is provided with a housing 12 for fixing the smoke tube 3, and the housing 12 is vertically disposed on the flange 1, so that the flange 1 is tightly connected to the smoke tube 3, and the smoke tube 3 is sealed with a gas water heater, a wall-mounted gas stove, and other machines.
