DETAILED DESCRIPTION

[0016] FIG. 1 shows a side elevation view of a drain cleaning device 100 in accordance with some implementations. The drain line cleaning device 100 includes a removable lower section 103 that includes a tapered end 102 that includes apertures forming a serrated edge that can be used to remove excess glue within a drain line by rotating the tapered end 102 within a pipe. The removable lower section 103 also includes a lower portion 104 that is constructed to be inserted within an interior of a condensate drain line. The removable lower section 103 also includes an optional elastomeric gasket 106 to help seal the removable lower section 103 to a condensate drain line. The removable lower section 103 further includes a fluted opening 108 that is operable to connect to a corresponding element 110 on the drain line cleaning device 100 via a threaded connection (e.g., NPT) or operable to serve as a funnel for pouring a cleaning solution (e.g., bleach) into a condensate drain line.

[0017] The drain line cleaning device 100 include an angled connector 112 (e.g., a 90 degree connector), a threaded coupler 114, a valve 116, a hose 118, an internal line 120, a pump 122, a pressure relief valve 124, and a tank body 126.

[0018] As shown in FIG. 2, the drain line cleaning device 100 is constructed to be inserted into a plumbing connector (e.g., tee 202). In FIG. 2, the plumbing connector 202 connects a condensate line 204 coming from a source of condensate (or other fluid) such as an air handler to a drain line 206 that carries the condensate to a drainage area (e.g., outside of a building or into a sewage line, etc.).

[0019] The drain cleaning device 100 lower portion 104 is inserted (e.g., via an interference fit) into an opening of the drain line 206 via connector 202.

[0020] In operation, air and fluid in the tank 126 is pressurized via the pump 122. When the valve 116 is opened, fluid from the tank 126 flows under the urging of the pressure within the tank 126 out the interior line 120 and through the hose 118 to the lower portion 103 to supply fluid (e.g., water, air, or cleaning fluid such as a bleach solution) to help clean and clear the drain line 206 of buildup (e.g., mold, slime, etc.) or debris, while preventing the fluid from flowing back into condensate line 204.

[0021] FIG. 2 shows an exploded view of a condensate drain line cleaning device 100 in accordance with some implementations. FIG. 2 shows the condensate line 204 from the equipment (e.g., air handler) connected to a fitting 202 (e.g., a tee) an on to the drain line 206.

[0022] FIG. 3 shows a close up view of the lower portion 103 being twisted within the drain line 206 to cause the tapered end 102 to help remove excess adhesive 302 when the lower portion 103 is rotated within the drain line 206.

[0023] FIG. 4 shows the lower portion 103 inserted into the drain line 206 such that the tapered end 104 engages the top of the drain line 402 in an interference fit and the elastomeric seal 106 engages the top of the fixture 202 to help provide a seal to prevent cleaning fluid from leaking from the drain line cleaning device when in use cleaning a drain line 206.

[0024] In operation, fluid (e.g., water, cleaning solution such as a bleach solution, etc.) can be sprayed into the drain line 206 by the pressurized tank 126.

[0025] FIG. 5 shows an example tapered end 104 having one or more flexible baffles 502 that are operable to engage the inside wall of a drain line (e.g., 206) and help create a seal to prevent cleaning fluid from escaping around the tapered end 104.

[0026] FIG. 6 shows an exploded view of a removable lower section 600 of a drain line cleaning device in accordance with some implementations. The removable lower section 600 includes an integrated angle 602 (e.g., a 90 degree), a tapered portion 604, a plurality of flexible baffles 606, a threaded coupler 608, and a valve 610.

[0027] The tapered portion 604 is constructed from a flexible material (e.g., neoprene rubber) to create a seal when inserted within an interior of a condensate drain line.

[0028] FIG. 7 shows a side elevation view of an example drain cleaning device with flexible baffles inserted into a drain line in accordance with some implementations. FIG. 7 shows an integrated angle 602 (e.g., a 90 degree), a tapered portion 604, a plurality of flexible baffles 606, a threaded coupler 608, and a valve 610, a top of the drain line 702, a condensate line 704 from the equipment (e.g., air handler), a drain line 706.

[0029] The lower portion 600 inserts into the drain line 706 such that the tapered portion 604 engages the top of the fixture 702 to help provide a seal to prevent cleaning fluid from leaking from the drain line cleaning device when in use cleaning a drain line 706.

[0030] FIG. 8 shows a side elevation view of a drain cleaning device in accordance with some implementations. The drain line cleaning device 800 include a lower portion 600, a tank body 802, a pressure relief valve 804, a pump 806, an outlet 808, and a hose 810.

[0031] FIG. 9 shows a side elevation view of an example drain cleaning nozzle section with flexible baffles 900 in accordance with some implementations. The removable lower section 900 includes a cleaning nozzle 902, a tapered portion 904, a plurality of flexible baffles 906, an angled connector 908 (e.g., a 90 degree), and a threaded coupler 910.
