Taken as a whole, the present disclosure reveals various drain guns, their accessories, and methods of their use and manufacture. For example, a drain gun may include a handle and a trigger. The handle can include channels and inlets, which can include check valves. The inlet including the non-return valve may feed the channel. When the cartridge is stored in the handle and feeds the inlet (including the check valve), the trigger can cause fluids from cartridges to be released in stages from the inlet (including the check valve) to the channel. Therefore, when the drain line is blocked, the drain line can be unblocked through the drain gun. For example, the drain line may drain from a heating, ventilation, and air conditioning (HVAC) system, refrigeration system, or other system. For example, the drain line may conduct condensate (eg, water) produced by at least some operation of the HVAC system, the refrigeration system, or other systems. In addition, various hoses, fittings and adapters are provided which can work with the drain gun and other hoses, fittings, tips and adapters for unclogging the drain line. For example, some of these include expandable tip adapters, tether shuttles, extended grip stepped plugs, and venturi effect suction connectors. Note, however, that this disclosure may be embodied in many different forms and should not be construed as necessarily limited to the various embodiments disclosed herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the various concepts of the disclosure to those skilled in the art.

It should be noted that various terms used in this text may imply Action or inaction, direct or indirect, total or partial, temporary or permanent. For example, when an element is referred to as being "on," "connected" or "coupled to" another element, the element may be directly on, connected or coupled to the other element or intervening elements may be present, including indirect or direct variations. In contrast, when an element is referred to as being "directly connected" or "directly coupled" to another element, there are no intervening elements present.

As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms unless the specific context clearly dictates otherwise.

FIG. 1 shows an embodiment of a drain gun according to the present disclosure. In detail, the water discharge gun 100 includes a handle 102 , a trigger 104 and a barrel 106 . The trigger 104 and barrel 106 are coupled (eg, assembled, fastened, mated, interlocked, integrated) to the grip 102 . The grip 102, trigger 104, and barrel 106 may comprise plastic, metal, rubber, or other materials. Although the handle 102, trigger 104, and barrel 106 are described with respect to one lateral side (e.g., the left side) of the water discharge gun 100, note that any side (e.g., front, rear, left, right) of the water discharge gun 100 may be configured as disclosed herein.

The handle 102 (e.g., housing, housing, frame) defines a Opening 108 (eg, closed shape, open shape, symmetrical, asymmetrical, O-shaped, D-shaped, rectangular, square, oval, circular, triangular), a tie, hook (eg, belt hook), or carabiner may extend through opening 108 . The handle 102 carries a safety lock 110 that is movable (eg, lateral, longitudinal, pivotable, hinged, mated, fastened, interlocked) between an open position and a closed position, as further disclosed below. For example, trigger 104 may be configured so that it cannot be depressed when safety lock 110 is in the closed position. For example, safety lock 110 may be manually movable (eg, user movable) or may be automatically movable between the open position and the closed position.

Grip 102 carries a plate 112 that defines a pair of openings for a plurality of displays 114 . The opening can have any shape (eg, symmetrical, asymmetrical, closed shape, open shape, O shape, D shape, rectangular, square, oval, circular, triangular). It should be noted that the openings are identical to each other in terms of type, shape or structure. However, the openings may differ from one another in type, shape, or configuration (and the handle 102 may be adapted for such variations). Display 114 is analog, but can be multi-color (eg, monochrome, color). For example, when the display 114 is optional and when the handle 102 includes a battery that may be rechargeable or replaceable, the battery may power the display 114 . Display 114 may output content, such as binary content (e.g., black/white, red/green, 1/0, full/empty) or gradient content (e.g., counter, odometer, scale/range, red/yellow/green, full/half full/empty), as further disclosed below. It should be noted that the displays 114 are identical to each other in type, shape, weight, form or structure. However, the display 114 is different in type, shape, weight, form or structure Aspects may differ from one another (and grip 102 may be adapted for such variations).

The handle 102 carries a plurality of covers 116 that can be opened and closed (eg, pivot, slide, separate), as further disclosed below. The cover 116 includes a plurality of openings 118 . The opening 118 is tapered in shape, but the shape can vary (eg, symmetrical, asymmetrical, closed shape, open shape, D shape, O shape, rectangular, square, oval, circular, triangular). The opening 118 can hold windows (eg, transparent, translucent, glass, plastic) or net/screen/grid, or avoid loading the window or net/screen/grid, and thus enable direct access into the handle 102 . It should be noted that the cover 116 can also avoid the opening 118 . It should be noted that the covers 116 are identical to each other in type, shape, weight or construction. However, the covers 116 may differ from one another in type, shape, weight, or configuration (and the handle 102 may be adapted for such variations).

The handle 102 carries a plurality of latches 122 . The latch 122 is configured to engage the cover 116 when the cover 116 is closed (eg, pivoted closed, slide closed, attached closed), as further disclosed below. It should be noted that the latches 122 are identical to each other in type, shape, weight or construction. However, the latches 122 may vary from one another in type, shape, weight, or configuration (and the handle 102 may be adapted for such variations). It should be noted that although the handle 102 includes a latch 122 , there may be a single latch 122 .

The handle 102 stores a plurality of magazines 120 that are dependent or independent from each other. For example, there may be two, three, four, five, six, seven, eight, nine, ten or more magazines 120 stored in the handle 102 indivual. Cassette 120 is visible through opening 118 . The handle 102 and the storage box 120 are arranged side by side in sequence. However, the handle 102 may store the pods 120 differently, such as forming a stack of pods 120 of any shape (eg, circular, oval, square, rectangular, octagonal, pentagonal, star, crescent). It should be noted that the handle 102 can also store a single pocket 120 , whether or not the handle 102 is configured to store at least two of the pockets 120 . For example, the handle 102 may be configured to receive and only store a single cartridge 120 .

Cassette 120 may store a plurality of fluids (eg, gas, liquid) under pressure. For example, a fluid may comprise a compressed gas (eg, air, carbon dioxide, nitrogen, hydrogen), whether the compressed gas system is flammable or non-flammable. For example, at least one of cartridges 120 may be a disposable sixteen gram steel carbon dioxide cartridge. It should be noted that although the pods 120 are identical, the pods 120 may differ from each other in type, shape, weight, volume, texture, content or structure (and the handle 102 may be adapted for such variations). Likewise, fluids may or may not be identical to one another in content, chemistry, type, pressure, color, temperature, volume, or other fluid characteristics (and drain gun 100 may be adapted for such changes). It should be noted that at least one of the cartridges 102 can store at least two fluids (e.g., at least two liquids, at least two gases, at least one liquid, and at least one gas), whether identical or different from each other in terms of content, chemistry, type, pressure, color, temperature, volume, or other fluid characteristics. In one mode of operation, the drain gun 100 provides a staged release of fluid from the cartridge 120 through the barrel 106 as actuated via the trigger 104 .

Figure 2 shows an embodiment of a drain gun according to the present disclosure. detailed In other words, the water discharge gun 200 is similar to the water discharge gun 100 . However, there are some differences. Drain gun 200 includes a handle 210 defining a plurality of openings 212 . The opening 212 is bidirectionally tapered in shape, but the shape can vary (eg, symmetrical, asymmetrical, closed shape, open, D-shaped, O-shaped, rectangular, square, oval, circular, triangular, unidirectional tapered). It should be noted that the openings 212 are identical to each other in terms of type, shape or structure. However, openings 212 may differ from one another in type, shape, or configuration (and handle 210 may be adapted for such variations). Opening 212 can hold windows (eg, transparent, translucent, glass, plastic) or net/screen/grid, or avoid loading windows or net/screen/grid, and thus enable direct access into handle 210 . It should be noted that the handle 210 avoids the opening 212 . Further, it should be noted that the windows or nets/screens/grids are identical to each other in type, shape, weight or structure. However, the windows or nets/screens/grids may differ from each other in type, shape, weight or configuration (and the handle 210 may be adapted for such variations).

The handle 210 carries the safety lock 202, which is movable (eg, longitudinal, transverse, pivotable, hinged, mated, fastened, interlocked) between an open position and a closed position. The handle 210 carries a plate 204 that defines a cavity 206 (e.g., closed, open, symmetrical, asymmetrical, O-shaped, D-shaped, rectangular, square, oval, circular, triangular) through which fasteners 208 (e.g., bolts, screws) secure the plate 204 to the handle 210. It should be noted, however, that the fasteners 208 may not be present and the plate 204 otherwise secured to the handle 210 (eg, adhered, fitted, interlocked, magnetized).

The handle 210 carries a plurality of caps 214 to which the caps 214 are coupled (eg, fastened, fitted, snapped, interlocked). The cap 214 may include plastic, metal or other materials. The cap 214 is grooved, raised or knurled on the outside to enhance grip, but could be tied smooth on the outside. Cap 214 may have any shape (eg, tubular, cylindrical, domed, cuboid, cubic, hemispherical, pyramidal, conical). It should be noted that the caps 214 are identical to each other in type, shape, weight or structure. However, caps 214 may differ from one another in type, shape, weight, or configuration (and handle 210 may be adapted for such variations).

FIG. 3 shows an embodiment of a trigger action of a drain gun according to the present disclosure. In detail, the drain gun 100 (or the drain gun 200 ) includes the handle 102 of the loading channel 134 , a plurality of inlets 138 , a plurality of check valves 126 and a plurality of nozzles 136 .

The channel 134 is longitudinally rectilinear between the barrel 106 and the safety lock 110, but may be longitudinally non-rectilinear (eg, arcuate, sinusoidal). Channel 134 has a circular transverse cross-section, but may have a non-circular transverse cross-section (eg, square, rectangular, oval, triangular). Channel 134 is a hollow tube (eg, metal, plastic) extending within handle 102 , but could be a hollow cavity defined within handle 102 . Channel 134 may extend between opening 108 and cavity 206 .

Channel 134 has a front end portion (eg, open) and a rear end portion (eg, open). A leading portion of the channel 134 feeds the barrel 106 (eg, fluid communication between the leading portion of the channel 134 and the barrel 106 ). Thus, at least some of the output from the front end of channel 134 is directed to the gun Tube 106. A rear end portion of the channel 134 is proximate (eg, within about 2 inches) of the safety lock 110 and is operably engaged therewith, as further disclosed below.

The inlet 138 is longitudinally rectilinear between the barrel 106 and the safety lock 110, but may be longitudinally non-rectilinear (eg, arcuate, sinusoidal). The inlet 138 has a circular transverse cross-section, but may have a non-circular transverse cross-section (eg, square, rectangular, oval, triangular). Each of the inlets 138 is a hollow tube (eg, metal, plastic, rubber) extending within the handle 102 , but could be a hollow cavity defined within the handle 102 . Cavity 206 may be positioned between inlets 138 . The inlet 138 feeds the channel 134 (eg, fluid communication between the channel 134 and the inlet 138 between the front end portion of the channel 134 and the rear end portion of the channel 134). For example, inlet 138 and channel 134 define a U-shape or a C-shape, but other shapes (eg, J-shape, S-shape) are possible. Accordingly, at least some output from inlet 138 is directed to channel 134 between a front portion of channel 134 and a rear end portion of channel 134 . It should be noted that the inlets 138 are identical to each other in type, shape, weight or configuration. However, the inlets 138 may differ from one another in type, shape, weight, or configuration (and the handle 102 may be adapted for such variations).

Inlet 138 may house (eg, internally) check valve 126 between barrel 106 and safety lock 110 . Each of the check valves 126 (eg, one-way valves) allows fluid (eg, gas, liquid) to flow therethrough in only one direction. The check valve 126 may be a dual port valve (eg, two body openings, one for fluid entry and one for fluid exit). The check valve 126 can be made of plastic, metal, rubber or other materials. The check valve 126 may comprise a spherical check valve Check valve, diaphragm check valve, swing check valve, stop check valve, lift check valve, in-line check valve, duckbill valve, pneumatic check valve or other check valves. The check valve 126 may be configured to pierce or pierce the cartridge 120 (eg, seal, cap, neck, top, sidewall) when the check valve 126 engages the cartridge 120 via the nozzle 136 . For example, the check valve 126 may be loaded with a needle (e.g., linear, non-linear) or blade (e.g., linear, non-linear) configured to pierce or pierce the cassette 120 (e.g., seal, cap, neck, top, sidewall) when the check valve 126 is engaged with the cartridge 120 via the nozzle 136. It should be noted that the check valves 126 are identical to each other in type, shape, weight, form or structure. However, the check valves 126 may differ from one another in type, shape, weight, form, or configuration (and the handle 102 may be adapted for such variations). The check valves 126 are operable independently of each other or dependent on each other. Check valve 126 (and handle 102 ) may allow independent loading of cartridge 120 . It should be noted that although drain gun 100 (or drain gun 200 ) is described as having check valve 126 , drain gun 100 (or drain gun 200 ) could employ a non-return valve (eg, flow control valve, two-way valve). The check valve 126 feeds the channel 134 (eg, the check valve 126 is in fluid communication with the channel 134 between the front end portion of the channel 134 and the rear end portion of the channel 134 ). Accordingly, at least some output from check valve 126 is directed to passage 134 between a forward portion of passage 134 and a rearward portion of passage 134 .

The inlet 138 is coupled to the nozzle 136 (eg, fastened, fitted, retracted, adhered, magnetized, sealed, integrated, assembled). Nozzle 136 is configured to receive cassette 120 (eg, fasten, mate, interlock). Thus, when the cartridge is received within the handle 102, the cartridge 120 can be inserted into the nozzle 136 (eg, longitudinally) and the nozzle 136 can receive (eg, tightly, loosely, securely, magnetically, securely) the cartridge 120 . For example, cartridge 120 may be threaded into nozzle 136 or magnetically attached to nozzle 136 .

The trigger 104 is coupled to a poppet valve 124 (eg, mechanical linkage, gear, rod, cable, spring, shape memory material, pulley, hinge, cam, electric motor, actuator). The poppet valve 124 may be tied to a single poppet valve 124 for the check valve 126 , or may be tied to at least two poppet valves 124 for the check valve 126 (eg, in a one-to-one correspondence).

Grip 102 stores (eg, temporarily, permanently) magazine 120 . Cassette 120 may be positioned between latch 122 and channel 134 or opening 108 . Cavities 206 may be positioned between cassettes 120 . The box 120 has a plurality of necks 132 and a plurality of bodies 130 . Neck 132 extends longitudinally from body 130 and is narrower in outer diameter than body 130 . For example, at least one of cartridges 120 may be a disposable sixteen gram steel carbon dioxide cartridge. For example, the handle 102 can be configured to secure the cartridge 120 based on the cartridge 120 being secured into the nozzle 136, and thereby push the neck 132 into the nozzle 136, where the cartridge 120 is pierced or pierced (e.g., seal, cap, neck, top, sidewall), sealed, and activated for use. Although the neck 132 and body face each other within the handle 102, the neck 132 and body may be offset relative to each other (eg, one pocket 120 is closer to the channel 134 than the other pocket 120, one neck 132 is closer to the channel 134 than the other neck 132).

The grip 102 carries the safety lock 110 opposite the barrel 106 near the rear end portion of the channel 134 (eg, within about 2 inches). Safety lock 110 is shown around a shaft extending into handle 102 (eg, straight, A non-linear, arcuate, sinusoidal, plastic, metal, rod, bolt, screw) pivotable lever (e.g., manually, automatically) wherein the lever is pivotable (e.g., manually, automatically) between an open position and a closed position. For example, the lever may pivot toward the opening 108 (eg, an open position) or away from the opening 108 (eg, a closed position), or vice versa. It should be noted that although the safety lock 110 is described as a lever, the safety lock 110 may include buttons, sliders, dials, or other input devices, whether in addition to or instead of the lever. Trigger 104 and safety lock 110 (e.g., a lever) may be mechanically connected to each other (e.g., mechanical linkages, gears, rods, cables, springs, shape memory materials, pulleys, hinges, cams, electric motors, actuators) such that at least some operation of trigger 104 is dependent on safety lock 110 being in a closed position or an open position (e.g., controlled by a user).

When the safety lock 110 is in the closed position (e.g., away from the opening 108) and the trigger 104 is at the preset position 128 (e.g., zero stage), then the rear end portion of the channel 134 avoids at least some fluid communication with the ambient environment outside the rear end portion of the channel 134 (e.g., the exterior of the handle 102). Thus, this configuration can create a state in which, when the trigger 104 is depressed (e.g., not depressed), the poppet valve 124 is effectively reduced, minimized, or prevented (e.g., negative pressure, vacuum, movement stop) via actuation of the trigger 104 and the trigger 104 remains at the preset position 128.

When safety lock 110 is in the open position (e.g., moved toward opening 108) and trigger 104 is in first position 127 (e.g., first stage), then the rear end portion of channel 134 is in at least some fluid communication with the ambient environment outside the rear end portion of channel 134 (e.g., the exterior of handle 102). Knot As a result, this configuration can create a state in which the poppet valve 124 is lifted, moved back or forward, or moved sideways via the trigger 104 being in the first position 127 (eg, partially depressed). Thus, this positioning of poppet valve 124 allows at least one of check valves 126 to take at least some fluid from at least one of cassettes 120 to travel along path 140 through at least one of inlets 138, respectively, and direct the fluid into passage 134, which in turn directs fluid to the forward end portion of passage 134 and then into barrel 106 for subsequent output therefrom. It should be noted that such a state may also keep at least one of the check valves 126 closed such that at least some fluid from at least one of the cassettes 120 does not travel along the path 140 and is not input into the channel 134 via at least one of the inlets 138, respectively. Thus, releasing the trigger 104 such that the trigger 104 moves from the first position 127 to the preset position 128 will in turn enable the poppet valve 124 to be lifted, moved backwards or forwards or sideways, and thereby close or close at least one of the check valves 126 and effectively prevent or reduce at least some fluid flow from at least some cassettes 120 along the path 140. It should be noted that at least some of the fluid in cartridge 120 flows from body 130 to neck 132 , which extends within nozzle 136 , and then along path 140 via inlet 136 to check valve 126 , and then to passage 134 , and then to barrel 106 . Further, it should be noted that the trigger 104 can avoid contacting the grip 102 in the first position 127 in at least two places (eg, inside and outside).

When the safety lock 110 is in or remains in the open position (e.g., moving toward the opening 108) and the trigger 104 is in or further moved from the first position 127 to the second position 129 (e.g., the second stage), then passage 134 is followed by The end portion is tied or maintained in at least some fluid communication with the ambient environment outside the rear end portion of the channel 134 (eg, the exterior of the handle 102 ). As a result, this configuration can create a state in which the poppet valve 124 is further lifted, moved rearward or forward, or moved sideways via the trigger 104 being in or further moved to the second position 129 (eg, fully depressed). Accordingly, this positioning of poppet valve 124 allows at least one of check valves 126 (eg, different from one during the first stage) to take at least some fluid from at least one of cassettes 120 to travel along path 142 through at least one of inlets 138, respectively, and direct the fluid into passage 134, which in turn directs fluid to the leading end portion of passage 134, and then into barrel 106 for subsequent output therefrom. For example, trigger 104 may contact grip 102 in second position 129 in at least two positions (eg, inner and outer). It should be noted that this state may also maintain or enable at least one of the check valves 126 to be closed (eg, different from one during the first phase) or be closed such that some fluid from at least one of the cassettes 120 does not travel along the path 142 and is not input into the channel 134 via at least one of the inlets 138, respectively. It should be noted that this state may also allow the non-return valve 126 to remain open when the corresponding cassette 120 is empty. Thus, releasing the trigger 104 so that the trigger 104 moves or moves further from the second position 129 to the first position 127 or the preset position 128 will in turn enable the poppet valve 124 to be lifted, moved back or forward, or moved sideways or further lifted, moved back or forward, or moved sideways, and thereby close or close or further close or close at least one of the check valves 126 and effectively stop or reduce or further reduce at least some fluid flow along the path 142 from at least some of the cassettes 120 . It should be noted that at least Some fluid flows from body 130 to neck 132 , which is located within nozzle 136 , and then along path 142 through inlet 136 to check valve 126 , and then to passage 134 , and then to barrel 106 .

It should be noted that although FIG. 3 shows a staged release from magazine 120 based on movement of trigger 104 between preset position 128, first position 127, and second position 129, drain gun 100 (or drain gun 200) may be configured to be simultaneously released from magazine 120 based on trigger 104 moving from preset position 128 to first position 127 or second position 129 or vice versa. It should be noted that the trigger 104 can be configured to provide a tactile output (e.g., vibration, impact) to at least one of the preset position 128, the first position 127, or the second position 129 as the trigger 104 is moved between the preset position 128, the first position 127 (e.g., the first stage), and the second position 129 (e.g., the second stage). Thus, when cartridge 120 is stored in handle 102 and fed to check valve 126 , trigger 104 may cause a staged release of fluid from cartridge 120 from check valve 126 to passage 134 along paths 140 and 142 .

It should be noted that while FIG. 3 shows a staged release occurring from the rightmost cassette 120 to the leftmost cassette 120 , the staged release can be reversed and thus occur from the leftmost cassette 120 to the rightmost cassette 120 . If the grip 102 stores more than two magazines 120 (e.g., three or more), the staged release may be fixed in sequence, user adjustable in sequence (e.g., a knob, button, or switch on the handle 102 that controls the staged release sequence), sequential in sequence (e.g., toward trigger 104, away from trigger 104), sequentially parallel, or otherwise.

It should be noted that the handle 102 can be constructed to control the 120 degrees of fluid release in stages. For example, one of the cassettes 120 may output one pressure, while the other cassette 120 may output another pressure. Such control over the degree of staged release from cartridge 120 may be accomplished, for example, via handle 102 having a user interface (e.g., button, knob, lever, switch, touch screen) that controls (e.g., mechanically, electronically) at least one of channel 134, at least one of inlet 138, or at least one of check valve 126. For example, such a form of control may widen or narrow at least one of channel 134 or inlet 138 . For example, such a form of control may increase or decrease the amount of fluid input or output through at least one of the check valves 126 .

Figure 4 shows an embodiment of a plurality of displays of a drain gun according to the present disclosure. Figure 5 shows an embodiment of a drain gun with a pressure gauge in accordance with the present disclosure. Figure 6 shows an embodiment of a drain gun according to the present disclosure with the cover in an open position. Figure 7 shows an embodiment of a drain gun according to the present disclosure with the cover in a closed position. Figure 8 shows an embodiment of a drain gun storing a plurality of cartridges according to the present disclosure. In detail, the drain gun 100 (or the drain gun 200 ) is loaded with the plate 112 defining the opening of the display 114 . The opening can have any shape (eg, open, closed, symmetrical, asymmetrical, O-shaped, D-shaped, rectangular, square, oval, circular, triangular). It should be noted that the openings are identical to each other in terms of type, shape or structure. However, the openings may differ from one another in type, shape, or configuration (and the handle 102 may be adapted for such variations).

The display 114 may be positioned on any side (eg, top, bottom, landscape, front, rear) of the handle 102 . Display 114 is analog, but can be multi-color (eg, monochrome, color). For example, When the display 114 is optional and when the handle 102 includes a battery that may be single use, rechargeable, or replaceable (eg, above the pocket, between the pockets, below the pocket), the battery may power the display 114. Display 114 may output content, such as binary content (e.g., black/white, red/green, 1/0, full/empty) or gradient content (e.g., counter, odometer, scale/range, red/yellow/green, full/half full/empty), as further disclosed below. For example, dual or gradient content (eg, backlight, phosphorescence) may be seen in the dark. It should be noted that the handle 102 has a lateral side on which the display 114 is mounted. For example, the handle 102 carries the display 114 above the cover 116 . For example, cover 116 may prevent loading of display 114 . However, the displays 114 may be distributed among (eg, opposite, adjacent to) multiple sides (eg, front, rear, lateral, top, bottom) of the handle 102 . The displays 114 are identical to each other in type, shape, weight, form or structure. However, displays 114 may differ from one another in type, shape, weight, form, or configuration (and grip 102 may be adapted for such variations).

The content is based on a plurality of pressure gauges 144 (eg, analog, digital, pressure gauges, pressure actuators, springs). Pressure gauge 144 is coupled (eg, mechanically, fluidly, electrically, thermally, optically) to display 114 and check valve 126 . For example, pressure gauge 144 may be positioned between display 114 and check valve 126 . For example. Pressure gauge 144 and check valve 126 may be a pair of distinct units or a single unit (eg, single housing, single chassis, single housing, single frame). For example, cover 116 may avoid housing pressure gauge 144 . Therefore, when the cartridge 120 is stored in the handle 102 and the engagement pressure Pressure gauge 144 monitors (eg, reads) at least some pressure of cartridge 120 while force gauge 144 and check valve 126 (which may pass through nozzle 136 ). For example, gauge 144 may monitor at least some pressure of cartridge 120 when check valve 126 is not inputting at least some fluid from cartridge 120 or outputting at least some fluid into inlet 138 while the cartridge is within nozzle 136 and engaged with check valve 126 . Thus, when at least some of the pressure of cartridge 120 measured via pressure gauge 144 reaches or meets or avoids meeting or avoids meeting a predetermined or dynamic threshold (e.g., empty, half full, half empty, full), then display 114 may adjust or render accordingly. It should be noted that the pressure gauges 144 are identical to each other in type, shape, weight, form or structure. However, pressure gauges 144 may differ from one another in type, shape, weight, form, or configuration (and handle 102 may be adapted for such variations).

The grip 102 includes a plurality of shafts 146 (eg, straight, non-linear, arcuate, sinusoidal) extending between the safety lock 110 and the barrel 106 . The shaft 146 may include plastic, metal or other materials. The shafts 146 are identical to each other in type, shape, weight, volume, texture or structure. However, the shafts 146 may differ from one another in type, shape, weight, volume, texture, or configuration (and the handle 102 may be adapted for such variations). It should be noted that although the shaft 146 corresponds to the cover 116 in a one-to-one correspondence, there may also be a single shaft 146 corresponding to the cover 116 .

The handle 102 includes a cover 116 pivotally coupled to a shaft 146 . It should be noted that the covers 116 are identical to each other in type, shape, weight, form or structure. However, the covers 116 may differ from each other in type, shape, weight, form, or configuration (and the handle 102 may be adapted for such be adapted to changes). Although the cover 116 is pivotally coupled to the shaft 146, the shaft 146 may be omitted and the cover 116 fastened, fitted, locked, or snapped onto the handle 102, but still pivotable relative to the handle 102 or removable from the handle 102. For example, the cover 116 may be pivotally engaged with the handle 102 via a plurality of C-shaped snap end seats.

Cover 116 carries a plurality of tails 148 (eg, assembly, integration) extending therefrom. Tail 148 is configured to engage latch 122 . Tail 148 extends from cover 116 such that a plurality of L-shapes are defined, but other shapes (eg, J-shape, V-shape) are possible. Tail 148 may engage latch 122 via mating, but other technologies (eg, interlocking, magnetized, hook and loop, snap) are also possible. It should be noted that the tails 148 are identical to each other in type, shape, weight, form or structure. However, the tails 148 may differ from one another in type, shape, weight, form, or configuration (and the handle 102 may be adapted for such variations).

Cover 116 carries a plurality of ribs 150 (eg, assembled, integrated) extending therefrom. Ribs 150 are configured to support cassette 120 . For example, the rib 150 can freely support the cassette 120 or couple (eg, fasten, glue, fit, interlock, magnetize, snap) to the cassette 120 . For example, the ribs 150 may mimic, conform to, or correspond in structure to the body 130 (eg, the curved ribs 150 correspond to the curved body 130 ). Ribs 150 extend from shroud 116 between shaft 146 and tail 148 such that a plurality of L-shapes are defined, although other shapes (eg, J-shapes, V-shapes) are possible. It should be noted that the ribs 150 are identical to each other in terms of type, shape, weight, form or structure. However, ribs 150 may vary in type, shape, weight, form or configuration. are different from each other (and the grip 102 can adapt to this variation).

The handle 102 includes a plurality of brackets 152 . Bracket 152 is configured to carry (eg, support, hold) cartridge 120 (eg, freely, snugly, securely, fit, fasten, magnetize, adhere, interlock, snap). Although a single tray 152 can load the magazine 120, the tray 152 may correspond to the magazine 120 in a one-to-one manner. When the cover 116 is closed, the cassette 120 is positioned between the bracket 152 and the cover 116 . It should be noted that handle 102 includes partition walls (eg, solid, perforated) defining a plurality of interior chambers of drain gun 100 (or drain gun 200 ), wherein the inner chambers accommodate brackets 152 in one-to-one correspondence. It should be noted, however, that the dividing wall may be omitted so that the drain gun 100 (or drain gun 200 ) has a single interior chamber containing the bracket 152 .

As shown in FIGS. 5-8 , the bracket 152 may be fixed within the handle 102 or travel within the handle 102 . For example, within the handle 102, the bracket 152 may travel toward the channel 134 and away from the latch 122, as shown in FIGS. 6-7. For example, within the handle 102 , the bracket 152 may contact the nozzle 136 as it moves toward the channel 134 and away from the latch 122 , or the nozzle 136 may act as a plurality of movement stops for the bracket 152 , as shown in FIG. 7 . Likewise, within the handle 102, the bracket 152 can travel away from the channel 134 and toward the latch 122, as shown in FIGS. 6 and 8 . Accordingly, carriage 152 may travel based on cover 116 being opened or closed, as shown in FIGS. 6 and 8 . For example, when the cover 116 is closed, the carriage 152 may travel toward the channel 134 and away from the latch 122 . For example, the carriage 152 may travel away from the channel 134 and toward the latch 122 when the cover 116 is opened.

Within the handle 102, the carriage 152 may travel based on mechanical linkages, gears, rods, cables, springs, shape memory material, pulleys, hinges, cams, electric motors, actuators, or others. Accordingly, the handle 102 may include a plurality of rods 156 that are coupled (eg, fitted, fastened, interlocked, magnetized, fastened) to the bracket 152 and to the cover 116 , whether identical or not. The shaft 156 is U-shaped, but this shape can vary (eg, C-shape, L-shape, T-shape). Likewise, the cover 116 has a plurality of protrusions 158 (eg, integrated, assembled, open, closed, symmetrical, asymmetrical, cammed, circular, oval, square, rectangular, pentagonal, octagonal, triangular). The protruding portion 158 is located distally of the tail portion 148 and the rib 150 . Accordingly, when cover 116 is pivoted closed, protrusion 158 engages lever 156 and thereby pulls (eg, lifts, pushes) bracket 152 to travel toward channel 134 and away from latch 122 . Likewise, when cover 116 is pivoted open, protrusion 158 engages lever 156 and thereby pushes (eg, lowers, pushes) bracket 152 away from channel 134 and toward latch 122 . It should be noted that, whether additionally or alternatively, within the handle 102, the bracket 152 may travel toward the channel 134 and away from the latch 122 based on at least some pushing, assisting, assisting, assisting, moving or guiding of the rib 150 based on the rib 150 being inserted, injected or positioned between the latch 122 and the bracket 152, as shown in FIG.

Bracket 152 is J-shaped, but this shape can vary (eg, L-shaped, U-shaped, C-shaped, P-shaped, T-shaped). It should be noted that at least one of the racks 152 may include a lower base configured (e.g., sized, dimensioned) to be stored upside down in the corresponding cassette 120 (e.g., storage, delayed activation), to carry, support, or receive at least one of the necks 132 with the corresponding body 130 proximate to the corresponding nozzle 136 (e.g., within about 2 inches) or not within the nozzle 136, but stored within the handle 102 and loaded within the corresponding bracket 152, as shown in FIGS. 5 and 8 . For example, the lower base may define an opening (e.g., open, closed, symmetrical, asymmetrical, O-shaped, D-shaped, circular, square, triangular, rectangular, pentagonal, octagonal) therein, wherein the opening is configured (e.g., sized, dimensioned) to receive the neck 132 extending therethrough, as shown in FIGS. 5 and 8 . For example, the opening may be shaped to match the outer contour of the neck 132, or to fit snugly therewith. Accordingly, the handle 102 may define an opening 154 therethrough (eg, open, closed, symmetrical, asymmetrical, O-shaped, D-shaped, circular, square, triangular, rectangular, pentagonal, octagonal). The openings 154 may be configured (eg, sized, dimensioned) to receive the necks 132 extending therethrough after the necks 132 extend through the openings of the base below the respective brackets 152 . It should be noted that the carriages 152 are identical to one another in terms of type, shape, weight, form, range of travel, direction of travel, or configuration. However, brackets 152 may vary from one another in type, shape, weight, form, range of travel, direction of travel, or configuration (and handle 102 may be adapted for such variations). It should be noted that the handle 102 can also avoid the bracket 152 .

9 shows an embodiment of a drain gun with a cap in an open position in accordance with the present disclosure. In detail, drain gun 200 is similar to drain gun 100 except for the various features disclosed below with respect to FIG. 2 .

The grip 210 is loaded with couplings thereto (e.g., fastening, mating, snap, interlock) cap 214. The cap 214 may comprise plastic, metal, rubber or other materials. The cap 214 is grooved, raised or knurled on the outside to enhance grip, but could be tied smooth on the outside. Cap 214 may have any shape (eg, tubular, cylindrical, domed, cuboid, cubic, hemispherical, pyramidal, conical). It should be noted that the caps 214 are identical to each other in type, shape, weight or structure. However, caps 214 may differ from one another in type, shape, weight, or configuration (and handle 210 may be adapted for such variations).

The cap 214 is attached to the handle 210 via a plurality of tethers 216 (eg, tethers, ropes, threads, chains, ties, ropes, braids, rods, shafts, planar members). The tether 216 is coupled to the handle 210 (eg, fastened, fitted, interlocked, adhered, magnetized, snapped, hooked and looped), whether identical or not. The tether 216 is coupled to the cap 214 (eg, fastened, fitted, interlocked, adhered, magnetized, snapped, hooked and looped), whether identical or not. Tether 216 may comprise plastic, metal, rubber, or other materials, whether identical or non-identical to each other. The tethers 216 may be rigid or flexible, whether identical or non-identical to each other. The tether line 216 can be retracted into or out of the handle 210 . For example, when retracted into the handle 210 , the tie line 216 may be positioned between the pocket 120 stored within the handle 210 between the cap 214 and the channel 134 . The tether 216 is long enough for the cap 214 to avoid interference with the insertion or removal of the cartridge 120 into or out of the handle 210 . Thus, the cartridge 120 is inserted into or removed (eg, dropped out, slid) from the handle 210 when the cap 214 is not controlled into or out of the handle 210 .

Figure 10 shows an embodiment of a drain gun having an opening in accordance with the present disclosure. In particular, the grip 102 defines an opening 108 (e.g., closed shape, open shape, symmetrical, asymmetrical, O-shaped, D-shaped, rectangular, square, oval, circular, triangular) through which a tie, hook (e.g., belt hook) or carabiner may extend. An opening 108 extends between the trigger 104 and the safety lock 110 .

11 shows an embodiment of a hose and tip adapter for use with a drain gun in accordance with the present disclosure. In particular, the system 1100 includes a tube 1102 (eg, plastic, metal, rubber, braided, armored, flexible, rigid, transparent, translucent, opaque, insulated, non-insulated) having a first end portion 1104 and a second end portion 1106 . For example, tube 1102 may be a flexible hose. The first end portion 1104 is configured for coupling (eg, fastening, fitting, interlocking, snapping, magnetizing, telescoping into/onto) the barrel 106 . The second end portion 1106 is configured to couple (eg, fasten, fit, interlock, snap, magnetize, retract into/onto) the tip adapter 1108 . Tip adapter 1108 is conical to fluidly engage a drain line, which may vary in width. For example, tip adapter 1108 may fluidly engage a drain line to form a seal. Thus, (1) the barrel 106 can be coupled to the first end portion 1104, (2) the tip adapter 1118 can be coupled to the second end portion 1106, and (3) the tip adapter 1118 can fluidly engage the drain line. Thus, drain gun 100 (or drain gun 200 ) may perform a staged output of fluid from cartridge 120 when trigger 104 is depressed toward handle 102 .

In one mode of operation, drain gun 100 (or drain gun 200) includes a handle 102 and a trigger 104. The handle 102 includes a channel 134 and a check valve 126 . Check valve 126 feeds passage 134 and when cartridge 120 is stored in handle 102 and feeds check valve 126 , trigger 104 causes a staged release of fluid from check valve 126 from cartridge 120 to passage 134 . Grip 102 may include pressure gauge 144 and display 114 , wherein display 114 may be presented based on pressure gauge 144 . A pressure gauge 144 monitors the cartridge 120 when it is stored in the handle 102 and engaged with the check valve 126 . Display 114 may be analogous and may present gradient content or duality content. The dual content may include a plurality of colors that are visually different from each other. The handle 102 may include lateral sides that carry the display 114 . Grip 102 may contain an interior chamber. The lateral sides may include a cover 116 that controls access to an interior chamber sized to accommodate the cassette 120 . Pressure gauge 144 and display 114 cannot be stowed through cover 116 . The handle 102 may carry a bracket 152 configured to move toward the channel 134 when the cover 116 is being closed, and wherein the bracket 152 is configured to carry the cassette 120 . Bracket 152 may be configured to move away from channel 134 when cover 116 is being opened. Cover 116 may include ribs 150 that engage brackets 152 when cover 116 is closed such that brackets 152 are positioned between ribs 150 and channel 134 . The handle 210 may include an internal chamber, wherein the handle 210 carries a cap 214 that controls access to the internal chamber, and wherein the internal chamber is positioned between the channel 134 and the cap 214 , and wherein the internal chamber is sized to accommodate the cartridge 120 . The cap 214 can be threaded onto the handle 210 and can be coupled to the handle 210 via a tie wire 216 configured to retract into the handle 210 when the cap 214 contacts the handle 210 . The handle 102 can define an opening 108 that is sized for use with a strap, belt hook, or carabiner. At least one of them is engaged, wherein passage 134 is positioned between opening 108 and check valve 126 . The staged release can include a plurality of stages, where the trigger 104 can provide a tactile output to at least one of the stages. The handle 102 may include a cover 116 , wherein the handle 102 includes an interior chamber, the cover 116 controlling access to the interior chamber, wherein the interior chamber is sized to accommodate the cartridge 120 . The handle 102 can carry a carriage 152 configured to move toward the channel 134 when the cover 116 is being closed, and wherein the carriage 152 is configured to carry the cartridge 120 . Cover 116 may include a rib 150 that engages bracket 152 when cover 116 is closed such that bracket 152 is positioned between rib 150 and check valve 126 . The handle 102 can carry a carriage 152 configured to move away from the channel 134 when the cover 116 is being opened, and wherein the carriage 152 is configured to carry the cartridge 120 . The handle 210 may include an internal chamber, wherein the handle 210 may carry a cap 216 that controls access to the internal chamber, and wherein the internal chamber is positioned between the channel 134 and the cap 214 , and wherein the internal chamber is sized to accommodate the cartridge 120 . The cap 214 can be threaded onto the handle 210 and the cap 214 can be coupled to the handle via a tether 216 that can be configured to retract into the handle 210 when the cap 214 contacts the handle 210 . Fluid from the cartridge 120 can define the full volume of the cartridge 120, which is dispensed immediately when the trigger 104 is pulled to full stroke. The handle 102 may include a safety lock 110 that prevents accidental discharge of the staged release. The handle 102 can be configured to store at least one of the cassettes 120 without piercing or puncturing (e.g., seal, cap, neck, top, sidewall) the at least one of the cassettes 120 while at least one of the cassettes 120 does not engage the check valve 126. For example, one method may include: Water gun 100 (or drain gun 200 ) is coupled to a blocked drain line. The drain gun 100 (or the drain gun 200 ) may be loaded with a cartridge 120 for storing fluid. The method may include controlled output of fluid from the drain gun 100 (or drain gun 200 ) in stages such that the drain line is unblocked via the fluid.

12a-12d show embodiments of accessories that may be used with a drain gun in accordance with the present disclosure. In detail, the expandable tip adapter 1200 includes a coupling portion 1202 and an insertion portion 1204 . Insertion portion 1204 is assembled (eg, fastened, mated, interlocked, adhered, magnetized, nested, mounted, frictionally engaged, clamped) with coupling portion 1202 , but may be integral therewith (eg, comprises a single piece of the same material). The coupling portion 1204 has or avoids having a common material (eg, plastic, metal, rubber, polyvinyl chloride (PVC), rigid, flexible, opaque, transparent, translucent) with the insertion portion 1204 .

Coupling portion 1202 includes an end portion 1206 (eg, plastic, metal, rubber) configured for coupling to drain gun 100 or drain gun 200 or tube 1102 or tip adapter 1108 or tip adapter 1216 (eg, mechanically, fluidly, mating, interlocking, adhering, magnetizing, nesting, mounting, frictionally engaging, clamping). For example, drain gun 100 or drain gun 200 may be coupled directly to end portion 1206 via threading thereto (eg, barrel 106 ), such that barrel 106 is in fluid communication with end portion 1206 . For example, drain gun 100 or drain gun 200 may be indirectly coupled to end portion 1206 via tube 1102, wherein tube 1102 is in fluid communication (e.g., mechanically coupled, fastened, fitted, interlocked, adhered, magnetized, nested, mounted, frictionally engaged, clamped) at one end thereof with barrel 106 on first end portion 1104 and in phase therewith. The opposite end is in fluid communication (eg, mechanically coupled, fastened, fitted, interlocked, adhered, magnetized, nested, mounted, frictionally engaged, clamped) with the end portion 1206 on the second end portion 1106 .

Insertion portion 1204 includes an expandable portion 1208 (e.g., rubber, latex, elastomer, shape memory) that extends longitudinally and cylindrically (e.g., straight, arcuate, sinusoidal) in a direction away from end portion 1206 (e.g., opposite, perpendicular, acute, obtuse). The expandable portion 1208 has a circular transverse cross-section, but can be other transverse cross-sections (eg, square, rectangular, triangular, octagonal, pentagonal, D-shaped, closed shape, open shape, symmetrical, asymmetrical) as well. As illustrated in Figure 12b, the expandable portion 1208 is in a deflated state. As illustrated in Figure 12d, the expandable portion 1208 is in an expanded state.

The expandable portion 1208 includes a plurality of ridges 1210 (eg, solid walls, perforated walls) extending circumferentially along the expandable portion 1208 and spaced apart from one another along the expandable portion 1208 . It should be noted that expandable portion 1208 may carry at least one of ridges 1210 or two or more of ridges 1210, whether identical or non-identical to each other in shape, structure, material, property, or otherwise. Ridge 1210 may extend perpendicular to expandable portion 1208 or non-perpendicular to expandable portion 1208 (eg, acute angle, obtuse angle). Ridges 1210 may be solid (eg, uniform height, variable height) or dashed (eg, uniform height, variable height). Regardless of whether the expandable portion 1208 is inflated, the ridges 1210 may intersect, face or overlap each other or avoid intersecting, facing or overlapping each other. The spacing may be equal (eg, parallel) or unequal (eg, non-parallel) regardless of whether the expandable portion 1208 is expanded. It should be noted that no Regardless of whether the expandable portion 1208 is inflated, the ridge 1210 can extend around or along the expandable portion 1208 helically, helically, or in a coil. Ridge 1210 is longitudinally circular, but can be other shapes (eg, oval, square, triangular, octagonal, pentagonal, D-shaped, open shape, closed shape, symmetrical, asymmetrical) as well. Spine 1210 is integral (e.g., comprising a single piece of the same material) with expandable portion 1208, but may be assembled therewith (e.g., mechanically coupled, fastened, fitted, interlocked, adhered, magnetized, nested, mounted, frictionally engaged, clamped) or may comprise at least some different material than expandable portion 1208.

Expandable portion 1208 includes an end portion 1210 remote from and opposite end portion 1206 . End portion 1210 protrudes outwardly away from end portion 1206 (eg, dome-shaped, conical, pyramid-shaped), but may be flat or indented (eg, depression, well) inwardly toward end portion 1206 . End portion 1210 is substantially closed (e.g., at least 50.1%, 51%, 66%, 75%, 80%, 85%, 90%, 95%, 97%, 99%) except for defining opening 1212, which may be positioned at its front edge (e.g., rounded, sharp corner) when present. It should be noted that the opening 1212 is circular, but can have different shapes (eg, slit, oval, square, triangular, octagonal, pentagonal, D-shaped, open shape, closed shape, symmetrical, asymmetrical). For example, the opening may be an elongated slit, a closed shaped slit, a circular slit, a crescent shaped slit or others. For example, end portion 1210 may include a set of openings 1212 (e.g., at least two, three, four, five, six, seven, eight, nine, ten, twenty) distributed around it (e.g., salt shaker style), whether randomly or according to Patterns (eg, asterisks, alphanumeric characters, logos, characters).

The expandable tip adapter 1200 is inserted into the open end of the tube 1214 (e.g., plastic, metal, rubber, PVC, rigid, flexible, opaque, transparent, translucent) such that the expandable portion 1208 is substantially within the tube 1214 (e.g., at least 50.1%, 51%, 66%, 75%, 80%, 85%, 90%, 95%, 97%, 99%, 100%) or as far as the tube 1214. The open end of 1214 engages (eg, contacts) coupling portion 1202 . For example, tube 1214 is or is in fluid communication with a drain line. When expandable portion 1208 is within tube 1214 and tube 1214 has an inner surface (eg, smooth, rough, knurled), ridge 1210 contacts or avoids contact with inner surface 1214 . Thus, at least one of the ridges 1210 can form a seal with the inner surface of the tube 1214, which seal can be airtight. It should be noted that at least some gas (eg, air) may remain between the ridge 1210 , the inner surface of the tube 1214 and the expandable portion 1208 .

In one mode of operation, expandable tip adapter 1200 has expandable portion 1208 inserted into the open end of tube 1214 . When drain gun 100 or drain gun 200 outputs fluid (e.g., gas, liquid) therefrom, expandable tip portion 1208 expands and thereby seals via at least one of ridges 1210, whether contacting or avoiding contact with the inner surface of tube 1214, and clamps against the inner surface of tube 1214 via at least one of ridges 1210, which prevents expandable tip adapter 1200 from slipping out of tube 1214. Opening 1212 allows at least some fluid (eg, gas, liquid) to progress through tube 1214 and unblock downstream tube 1214 . For example, the coupling portion 1202 may be connected to the barrel 106 or to the second end portion 1106 of the tube 1102 (wherein the first end portion 1104 is fluidly connected to the barrel 106). The insertion part 1204 is inserted into the tube 1214 in the open end. The drain gun 100 or drain gun 200 may then dispense fluid (eg, gas, liquid) therefrom. During dispensing, expandable portion 1208 expands and causes at least some of ridges 1210 to form a seal against the inner surface of tube 1214 . This seal enables at least some pressure to build up on end portion 1210 and thereby output fluid from opening 1212 and push at least some plugging material through and out of tube 1214 .

Figure 13 shows an embodiment of a shuttle that may be used with a drain gun in accordance with the present disclosure. Specifically, the shuttle 1300 includes a body 1302 carrying a plurality of spines 1304 . Shuttle 1300, including body 1302 and spine 1304, may comprise a material comprising or may be plastic, metal, rubber, latex, elastomeric, PVC, rigid, flexible, opaque, transparent, translucent, or other material. For example, shuttle 1300 may be implemented as a pipe plug.

Body 1302 includes a leading end portion 1306 and a trailing end portion 1308 . Body 1302 is longitudinally elongated (eg, straight, arcuate, sinusoidal) between leading edge end portion 1306 and trailing edge end portion 1308 . Body 1302 may be internally hollow between leading edge end portion 1306 and trailing edge end portion 1308 , or internally solid between leading edge end portion 1306 and trailing edge end portion 1308 . Body 1302 may include an internal passage (eg, straight, arcuate, sinusoidal) between leading edge end portion 1306 and trailing edge end portion 1308 . Body 1302 may be expandable (eg, gas, liquid) or non-expandable.

Ridges 1304 (eg, solid walls, perforated walls) extend circumferentially along body 1302 and are spaced apart from each other along body 1302 . It should be noted that the body 1302 can carry at least one of the spines 1304 or both of the spines 1304 or more, whether identical or non-identical to each other in shape, structure, material, properties, or otherwise. Ridge 1304 may extend perpendicular to body 1302 or non-perpendicular to body 1302 (eg, acute angle, obtuse angle). Ridges 1304 may be solid (eg, uniform height, variable height) or dashed (eg, uniform height, variable height). Regardless of whether the body 1302 is inflated, the ridges 1304 may intersect, face or overlap each other or avoid intersecting, facing or overlapping each other. Regardless of whether the body 1302 is expanded, the spacing may be equal (eg, parallel) or unequal (eg, non-parallel). It should be noted that regardless of whether the body 1302 is inflated, the ridge 1304 may extend helically, helically, or coiled around or along the body 1302 . Ridge 1304 is longitudinally circular, but can be other shapes (eg, oval, square, triangular, octagonal, pentagonal, D-shaped, open shape, closed shape, symmetrical, asymmetrical) as well. Ridge 1304 is integral with body 1302 (eg, comprises a single piece of the same material), but can be assembled therewith (eg, mechanically coupled, fastened, fitted, interlocked, adhered, magnetized, nested, mounted, frictionally engaged, clamped). The trailing end portion 1308 is coupled (e.g., fastened, fitted, interlocked, glued, bonded, looped, stitched, braided, magnetized, injected, fastened) to a leading end portion of a tether 1310 (e.g., tether, rope, cable, chain, rod, plunger, rope, braid, planar extension, X-shaped extension, helical extension, coiled extension, helical extension, stretchable extension, elastic extension, elastic extension, rigid extension). The line 1310 has a trailing end portion that can be coupled (e.g., fastened, fitted, interlocked, glued, bonded, looped, sewn, braided, magnetized, injected, tied) to the discharge gun 100 (e.g., the barrel 106, the handle 102) or the discharge gun 200 (e.g., the barrel 106, the handle 102) or Another device (eg, stationary, mobile, drain gun end effector, hose, fixture, furniture, appliance, pipe, air handler, building floor) or held manually (eg, arm, finger, palm, garment).

In one mode of operation, shuttle 1300 is inserted into the open end (e.g., inlet) of a drain line having an inner surface (e.g., smooth, rough, knurled) such that ridge 1304 contacts or avoids contact with the inner surface of the drain line, and shuttle 1300 can be propelled through by fluid from either drain gun 100 or drain gun 200, but can still be withdrawn from within the drain line by pulling on tether 1310, whether such pulling is manual or automatic (e.g., motor, actuator, reel). This form of travel can clear at least some obstructions from the drain line. For example, shuttle 1300 may be inserted into the open end of a drain line, either with or without tie line 1310, such that ridge 1304 faces the inner surface of the drain line. As a result, tether line 1310 drags body 1302 . Then, when drain gun 100 or drain gun 200 outputs fluid (eg, gas, liquid) therefrom, shuttle 1300 is propelled within the drain line and away from the open end of the drain line. The ridge 1304 may contact or avoid contact with the inner surface of the drain line. The leading edge portion 1306, body 1302, or at least some of the ridges 1304 can exert a positive force (eg, pressure) on the blockage within the drain line and can mechanically loosen or push the blockage longitudinally along the drain line, which can include an outlet thereto. Tether 1310 can then be pulled or retracted from the open end of the drain line (eg, fishing style) such that body 1302 can be extracted from the open end of the drain line from which body 1302 is launched. Alternatively, the body 1302 can be removed from the outlet of the drain line, with or without the tie line 1310 Tether 1310, which may depend on how the body 1302 is launched.

14a to 14e show embodiments of extended grip stepped plugs usable with a drain gun in accordance with the present disclosure. In detail, as shown in FIG. 14 a , extended grip stepped plug 1400 a includes a stepped section 1402 , wing nut section 1404 and joint section 1406 .

Stepped section 1402 includes a plurality of tubular members 1408 that are concentric with each other and gradually and longitudinally taper away from wing nut section 1404 (e.g., reduced outer diameter, reduced outer perimeter, reduced inner diameter, reduced inner perimeter) to accommodate various drain line inner diameter sizes. Stepped section 1402 comprises an inner channel (e.g., open shape, closed shape, symmetric, asymmetric, square, rectangular, triangular, pentagonal, octagonal, star-shaped, uniform inner width, varying inner width, tapered inner width) extending centrally through tubular member 1408. Stepped section 1402 includes an open end portion 1410 defining an opening in fluid communication with the inner channel (eg, open shape, closed shape, symmetric, asymmetric, square, rectangular, triangular pentagon, octagon, star).

Tubular member 1408 is circular, but this shape can vary (eg, open shape, closed shape, symmetrical, asymmetrical, square, rectangular, triangular, pentagonal, octagonal, star). Tubular members 1408 are identical to one another in shape, but differ in size from one another (eg, stepped). However, some tubular members 1408 may also differ in shape from each other (eg, round and oval). Tubular member 1408 has a smooth outer surface, but it can vary (eg, roughness, knurling, protrusions, bumps, depressions). Tubular members 1408 are integral with each other (e.g., comprise single piece), but can be assembled (e.g., adhered, magnetized, interlocked, fastened, mated, engaged) with each other. Tubular member 1408 may comprise elastic, elastomeric, flexible or shape memory material (eg, polymer, plastic, rubber, latex, silicon, nitinol).

Wing nut section 1404 includes a wing nut having wings outside stepped section 1402 and positioned between tubular member 1408 and joint section 1406 . The wings taper outwards, but this can vary (eg wings taper inwards, wings not tapered). Wing nut segment 1404 includes an inner channel (e.g., open shape, closed shape, symmetric, asymmetric, square, rectangular, triangular, pentagonal, octagonal, star-shaped, uniform inner width, varying inner width, tapered inner width) through which the center extends and is in fluid communication with the inner channel of stepped section 1402. Wing nut section 1404 may be rigid or flexible or of a different material than stepped section 1406 (eg, plastic, metal, rubber, PVC, rigid, flexible, opaque, transparent, translucent). The channels within stepped section 1402 and wing nut section 1404 can be co-aligned along a common axis, and the wing nut with wings can be rotated clockwise or counterclockwise about the common axis.

Fitting section 1406 (eg, plastic, metal, rubber, latex, shape memory, elastomer, PVC, rigid, flexible, opaque, transparent, translucent) includes an open end portion configured to fluidly couple (eg, fasten, mate, interlock, magnetize, adhere) to drain gun 100 or drain gun 200 or tube 1102 or tip adapter 1108 . Joint section 1406 may be rigid, resilient, resilient, shape memory, or flexible , whether linear or non-linear. For example, joint section 1406 may be rigid or shaped in various ways (eg, I-shape, L-shape, J-shape, S-shape, T-shape, plus-shape, X-shape). For example, joint section 1406 may bend between about 0 degrees and about 180 degrees in a single direction or in multiple directions (eg, living hinge, drinking straw hinge). For example, the joint section 1406 can bend between about 0 degrees and about or less than 170, 160, 150, 140, 130, 120, 110, 100, 90, 80, 70, 60, 50, 40, 30, 20, 10, or 5 degrees in a single direction or in a plurality of directions. Joint segment 1406 includes an inner channel (e.g., open shape, closed shape, symmetric, asymmetric, square, rectangular, triangular, pentagonal, octagonal, star-shaped, uniform inner width, varying inner width, tapered inner width) extending therethrough. The channel within the joint section 1406 and the channel within the wing nut section 1404 or the stepped section 1402 may be co-aligned along a common axis. Alternatively, a channel within joint section 1406 may extend through wing nut section 1404 and stepped section 1402 (eg, wing nut section 1404 and stepped section 1402 surround, extend around, or mount to joint section 1406). For example, wing nut section 1404 may be mounted over (eg, adhered, bonded to) the inner channel of joint section 1406 , and the inner channel of joint section 1406 may extend through the inner channel of wing nut section 1404 . Likewise, stepped section 1402 may be mounted over (eg, adhered, bonded to) the inner channel of joint section 1406 , and the inner channel of joint section 1406 may extend through the inner channel of stepped section 1402 .

In one mode of operation, stepped section 1402 is inserted into an open end (eg, into mouth), the drain line has an inner surface such that the opening of the open end 1410 is in fluid communication with the drain line and at least some of the tubular members 1408 face, contact or abut the inner surface. For example, stepped section 1402 may be inserted up to the inner diameter size of the closest matching drain line. At this point, wing nut segment 1404 can be rotated (e.g., tightened) clockwise or counterclockwise such that at least one of tubular members 1408 (e.g., matching the drain line inner diameter size) can expand outward to contact, grip, or seal, which can be sealed against the drain line inner surface. Thus, the stepped section 1402 can be inserted into the open end of the drain line when the drain line is blocked. Wing nut section 1404 can be tightened such that at least one of tubular members 1408 (eg, matching the drain line inner diameter size) can expand outward to contact, grip, or seal, which can seal against the drain line inner surface. Drain gun 100 or drain gun 200 or tube 1102 or tip adapter 1108 may be fluidly coupled (e.g., fastened, mated, interlocked) to joint section 1406 such that at least one of the cassettes may capture at least one of fluid entering into the drain line through joint section 1406, wing nut section 1404, and stepped section 1402, and thereby at least partially unclog the drain line.

As shown in FIGS. 14b and 14c , extended grip stepped plug 1400b includes stepped section 1402 and joint section 1406 , and extended grip stepped plug 1400c includes stepped section 1402 and joint section 1406 . However, extended grip stepped plug 1400b and extended grip stepped plug 1400c differ from extended grip stepped plug 1400a by having cam lever 1412 and cam lever 1416, respectively.

As shown in Figure 14b, the cam lever 1412 is shaped as The L-shape, as defined by base 1420 and post 1418 . However, it should be noted that the cam lever 1412 can have different shapes (eg, J-shape, C-shape, U-shape). The cam lever 1412 also includes a pivot 1422 (eg, straight, arcuate, sinusoidal) extending from the joint section 1406 into the base 1420, or vice versa. The pivot 1422 can be flush with the base 1420 or extend through the base 1420 . The pivot 1422 may be integral with the joint section 1406 (eg, comprising a single piece of the same material), or the pivot 1422 may be assembled (eg, fastened, fitted, interlocked, adhered, magnetized, engaged) with the joint section 1406 . Alternatively, the pivot 1422 may be integral with the base 1420 (eg, comprising a single piece of the same material), or the pivot 1422 may be assembled with the base 1420 (eg, fastened, mated, interlocked, adhered, magnetized, engaged). Post 1418 defines an interior opening 1414 configured such that joint section 1406 passes therethrough without bending when cam lever 1412 is rotated approximately 90 degrees about pivot 1422 . For example, opening 1418 may be rectangular, oval, L-shaped, or otherwise. It should be noted that joint section 1406 may be rigid or flexible.

As illustrated in Figure 14c, extended grip stepped plug 1400c differs from extended grip stepped plug 1400b in that joint section 1406 is L-shaped or bendable or flexible or springable or resilient, whereas extended grip stepped plug 1400c has a cam lever 1416 equipped with a post 1418 that lacks opening 1414 (e.g., solid), although post 1418 may be perforated or latticed. Thus, joint section 1406 maintains an L-shape while cam lever 1416 pivots about pivot 1422 . For example, joint section 1406 is L-shaped and can be used in tight spaces. It should be noted that the fitting section 1406 may be constructed so as to be remote from the hose or fitting to which the stepped section 1402 is fluidly coupled. The device can unblock the joint section 1406 regardless of the positioning of the cam lever 1412 or the cam lever 1416. For example, a hose or adapter may not need to be fluidly connected to joint section 1406 while cam lever 1412 pivots about pivot 1422 . Alternatively, the joint section 1406 is bendable or flexible or resilient or elastic, and as the cam lever 1416 pivots about the pivot 1422 , being urged by the post 1418 , bends or flexes accordingly.

In one mode of operation, stepped section 1402 is inserted into an open end (e.g., inlet) of a drain line (e.g., rigid pipe, flexible pipe) having an inner surface such that the opening of open end 1410 is in fluid communication with the drain line and at least some of tubular members 1408 face, contact, or rest against the inner surface. For example, stepped section 1402 may be inserted up to the inner diameter size of the closest matching drain line. At this point, cam lever 1412 or cam lever 1416 can be pivoted (e.g., secured) clockwise or counterclockwise about pivot 1422 such that at least one of tubular members 1408 (e.g., matched to the drain line inner diameter size) can expand outward to contact, grip, or seal, which can seal against the drain line inner surface. Thus, the stepped section 1402 can be inserted into the open end of the drain line when the drain line is blocked. Cam lever 1412 or cam lever 1416 can be rotated (eg, tightened) such that at least one of tubular members 1408 (eg, matched to the drain line inner diameter size) can expand outward to contact, grip, or seal, which can seal against the drain line inner surface. Drain gun 100 or drain gun 200 or tube 1102 or tip adapter 1108 may be fluidly coupled (e.g., fastened, mated, interlocked) to fitting section 1406 such that at least one of the cassettes may capture at least one of the fluid entering the drain line through fitting section 1406 and stepped section 1402 and thereby at least partially Unclog the drain line.

As shown in FIG. 14d , extended grip stepped plug 1400a includes joint section 1406 extending longitudinally and concentrically along a common axis through wing nut section 1404 and stepped section 1402 . In stepped section 1402 , joint section 1406 extends through tubular member 1408 . Thus, since the joint section 106 has a flange at one end thereof, when the wing nut is rotated about the common axis via the wings, whether clockwise or counterclockwise, the flange rotates in translation, thereby compressing and expanding the stepped section 1402 (e.g., tubular member 1408) against the inner surface of the drain line so that the stepped section 1402 can form a seal against the inner surface of the drain line.

As shown in FIG. 14e , extended grip stepped plug 1400b includes a joint section 1406 extending longitudinally and concentrically along a common axis through stepped section 1402 . Pivot 1422 is normal or perpendicular to the common axis, and cam lever 1412 pivots relative to joint section 1406 about pivot 1422 . Thus, upon such pivoting, base 1420 is positioned such that base 1420 compresses and expands outwardly stepped section 1402 (eg, tubular member 1408 ) against a drain line inner surface (eg, wine stopper).

15 shows an embodiment of a venturi effect suction fitting usable with a drain gun in accordance with the present disclosure. In detail, the venturi suction joint 1500 includes a first tubular portion 1502 , a second tubular portion 1504 and a third tubular portion 1506 . The first tubular portion 1502, the second tubular portion 1504, and the third tubular portion 1506 are configured to each other such that a T-shape is thereby defined. It should be noted, however, that such shapes can vary (eg, Y-shape, W-shape, M-shape, E-shape). For example, although the first tubular portion 1502 Orthogonal or perpendicular to the second tubular portion 1504, but the first tubular portion 1502 and the second tubular portion 1504 may form an acute or obtuse angle with each other. Likewise, although the third tubular portion 1506 and the second tubular portion 1504 are orthogonal or perpendicular to each other, the third tubular portion 1506 and the second tubular portion 1504 may form an acute or obtuse angle with each other. Similarly, although the first tubular portion 1502 and the third tubular portion 1506 are opposite in polarity to each other, the first tubular portion 1502 and the third tubular portion 1506 may form an acute angle, an obtuse angle, or a perpendicular or orthogonal angle with each other. At least two of the first tubular portion 1502, the second tubular portion 1504, or the third tubular portion 1506 are integral with each other (e.g., comprise a single piece of the same material), but can be assembled with each other (e.g., fastened, fitted, interlocked, joined, adhered, magnetized). At least one of the first tubular portion 1502, the second tubular portion 1504, or the third tubular portion 1506 may comprise plastic, metal, rubber, shape memory, or other material, whether rigid, elastic, elastomeric, resilient, or flexible, whether transparent, opaque, or translucent.

Each of the first tubular portion 1502, the second tubular portion 1504, and the third tubular portion 1506 includes an inner passage (e.g., open shape, closed shape, symmetric, asymmetric, square, rectangular, triangular, pentagonal, octagonal, star-shaped, uniform internal width, varying internal width, tapered internal width) extending therethrough, whether identical or non-identical to each other in terms of shape, orientation, diameter, cross-section, or other properties. The passages within the first tubular portion 1502 and the passages within the third tubular portion 1506 are in fluid communication with each other and may or may avoid co-alignment along a common axis. The inner channel of the second tubular part 1504 and the inner channel of the first tubular part 1502 and the third tube The channels within the shaped portion 1506 are in fluid communication. The channel within the second tubular portion 1504 is perpendicular or orthogonal to the channel within the first tubular portion 1502 or the channel within the third tubular portion 1506 . However, this can vary. For example, although the channels within the first tubular portion 1502 and the second tubular portion 1504 are orthogonal or perpendicular to each other, the channels within the first tubular portion 1502 and the second tubular portion 1504 may form an acute or obtuse angle with each other. Likewise, although the channels within the third tubular portion 1506 and the channels within the second tubular portion 1504 are orthogonal or perpendicular to each other, the channels within the third tubular portion 1506 and the second tubular portion 1504 may form an acute or obtuse angle with each other. Similarly, although the passages within the first tubular portion 1502 and the passages within the third tubular portion 1506 are opposite in polarity to each other, the passages within the first tubular portion 1502 and the third tubular portion 1506 may form an acute angle, an obtuse angle, or a perpendicular or orthogonal angle to each other.

The first tubular portion 1502 is configured for coupling (e.g., mechanical, chemical, fluid, fastening, mating, interlocking, adhering, magnetizing, engagement, friction, snuggling, nesting) to the drain gun 100 or the drain gun 200 or the tube 1102 or the tip adapter 1108 or a source of pressurized fluid (eg, an air tank, elastomeric bladder, inflatable bladder). The second tubular portion 1504 has a plurality of barbs or threads 1508 configured for coupling to a drain line (eg, outlet, inlet). It should be noted, however, that the second tubular portion 1504 can be configured to couple to the drain line in a variety of ways (eg, mechanical, chemical, fluid, fastening, fitting, interlocking, adhesive, magnetized, engaging, frictional, snug, nesting). The third tubular portion 1506 has a plurality of barbs or threads 1510 configured for coupling to a drain line (e.g., inlet, outlet mouth). It should be noted, however, that the third tubular portion 1506 may be configured to couple to the drain line in other ways (eg, mechanical, chemical, fluid, fastening, fitting, interlocking, adhering, magnetizing, engaging, frictional, snug, nesting). Accordingly, a venturi effect suction fitting 1500 may be used where at least some access to a drain line (eg, pipe, pipe) is limited or limited or difficult to obtain. In this case, the venturi effect suction fitting 1500 uses the venturi effect and pressurized fluid (eg, gas, liquid) to clear obstructions from the outlet of the drain line by suction.

In one mode of operation, first tubular portion 1502 is coupled (e.g., mechanically, chemically, fluidly, fastened, fitted, interlocked, adhered, magnetized, engaged, frictional, snug, nested) to an open end portion (e.g., rigid, flexible) of a hose or to drain gun 100 or drain gun 200 or an air tank or hose or accessory nozzle or adapter fitting or other, as otherwise disclosed herein, whether intermediate or fluid source. The second tubular portion 1504 is coupled (eg, mechanical, chemical, fluid, fastened, fitted, interlocked, adhered, magnetized, engaged, frictional, snug, nested) to an outlet of a blocked drain line (eg, conduit). The third tubular portion 1506 points in a secure direction or couples (eg, mechanically, chemically, fluidly, fastens, fits, interlocks, adheres, magnetizes, joins, frictions, snuggles, nests) to another tube or an adapter therefor. Next, a pressurized fluid (eg, gas, liquid, air, nitrogen, water) is input into the first tubular portion 1502 (eg, cartridge dispense, drain gun, air tank). Since the pressurized fluid is input at a high volume and the high volume of pressurized fluid flows from the first tubular portion 1502 to the third tubular portion 1506, at least some of this flow is in the second tubular portion Negative pressure (eg, suction, vacuum suction) is generated at 1504 . Since the second tubular portion 1504 is coupled to the outlet of the drain line, the negative pressure pulls (eg, suction) at least some blockages within the drain line toward the outlet of the drain line, and then into the second tubular portion 1504 and then into the third tubular portion 1504, which expels those blockages.
