Theinlet aperture 30 andoutlet aperture 34 generally remain above thereceptacle 18 while thecleaning device 10 is in the orientation of normal operation. Separating theinlet aperture 30 andoutlet aperture 34 from thebottom surface 28 of thereceptacle 18 helps prevent particles collected within thereceptacle 18 from obstructing theinlet passage 22 oroutlet passage 26. - In the illustrated construction, the
housing 14 may be solidly formed, and theinlet portion 22 andoutlet portion 26 may be integrally formed within thehousing 14. As shown inFIG. 4 , theinlet passage 22 andoutlet passage 26 are integrally formed passages within thehousing 14, and define at least a portion of a flow path for fluid through thehousing 14. In some constructions, thehousing 14 may be solidly formed from a molded plastic material, cast from a metal material, or solidly formed by other similar means. - In the construction shown in
FIG. 5 , thecleaning device 10 includes afilter 36 connected to theoutlet passage 26. InFIG. 5 , thefilter 36 includes a tube filter extending downwardly from theoutlet passage 26 through theoutlet aperture 34 and into thereceptacle 18. Thefilter 36 restricts particles, sediment, debris or waste in the water from passing through theoutlet aperture 34 into theoutlet portion 26. The water flows through thefilter 36 and into theoutlet portion 26, and the particles, sediment, debris and waste remains in thereceptacle 18. Thefilter 36 may include a mesh structure forming several apertures. The apertures may block particles that are larger than the apertures from entering theoutlet passage 26. - As shown in
FIGS. 1-6 , thecleaning device 10 includes atube 38 connected to thehousing 14 near anouter end 42 of theinlet passage 22. Theouter end 42 is at the end of theinlet passage 22 opposite theinlet aperture 30. Thetube 38 is in fluid communication with theinlet passage 22. Thetube 38 may be relatively rigid and includes anintake 46 at an end of thetube 38 opposite thehousing 14. In the illustrated construction, thetube 38 extends outwardly from thehousing 14 beyond thereceptacle 18. - As shown in
FIGS. 5 and 6 , thetube 38 may extend into theinlet passage 22 of thehousing 10. Theinlet passage 22 may include acurved portion 50 and astraight portion 54. Thecurved portion 50 extends upwardly from theinlet aperture 30 and curves around to a mid-portion of theinlet passage 22. Thestraight portion 54 extends downwardly from thecurved portion 50 to theouter end 42 of theinlet portion 22. In the illustrated construction, thestraight portion 54 and thetube 38 are generally co-linear and extend at an angle relative to thereceptacle 18. In the illustrated construction, thestraight portion 54 has a generally cylindrical shape having a diameter. - The
tube 38 extends into thestraight portion 54 through theouter end 42. Theinlet passage 22 includes aninner wall 58 that engages thetube 38. Theinner wall 58 defines thestraight portion 54 and thecurved portion 50. In the illustrated construction, thestraight portion 54 includes a slantedportion 62 in which theinner wall 58 slants inwardly. The diameter of theinlet passage 22 decreases along the slantedportion 62 as theinlet passage 22 progresses along thestraight portion 54 toward thecurved portion 50 and theinlet aperture 30. When thetube 38 is inserted into theinlet passage 22, theinner wall 58 along the slantedportion 62 provides an interference fit with thetube 38 and creates a seal between thetube 38 and theinlet passage 22. - In the illustrated construction, the
tube 38 may include acollar 66 that connects thetube 38 to thehousing 14. Thecollar 66 includesthreads 70 on aninner surface 74 of thecollar 66, and thehousing 14 includesthreads 78 on anouter surface 82 near theouter end 42 of theinlet passage 22. Thecollar 66 threadably engages thehousing 14 to create a seal between thetube 38 and theinlet portion 22. Thecollar 66 slides over thetube 38 and frictionally engages thetube 38. - As shown in
FIGS. 5 and 6 , thecollar 66 may include aflange 86 adjacent thetube 38. As theinner surface 74 of thecollar 66 is threaded onto theouter surface 82, theflange 86 extends into theinlet passage 22, between theinlet passage 22 and thetube 38. Theflange 86 may be angled and may deflect radially inwardly and clamp thetube 38 to hold thetube 38 in place and improve the seal between thetube 38 andinlet passage 22. - The length of the
tube 38 may vary depending on the desired application for thecleaning device 10. As shown inFIG. 1 , thetube 38 extends downwardly beyond thereceptacle 18. In some applications, such as cleaning a pond, an operator may hold thecleaning device 10 at approximately waist level, and thetube 38 extends into the water, which is relatively low in relation to the operator's feet. In some constructions for these applications, thetube 38 may extend between about three and six feet. It should be understood that the length of thetube 38 may vary and may be greater or less than that range. In some constructions for other applications, such as cleaning an aquarium, thetube 38 may be relatively shorter. Thetube 38 may be removed and replaced with atube 38 having the desired length. - In other constructions, the
tube 38 may include telescoping portions (not shown) that may be positioned to adjust thetube 38 to a desired length. In yet other constructions, thetube 38 may be integrally formed with thehousing 14. - As shown in
FIGS. 1-5 , thehousing 14 may include ahandle 90 to facilitate operation of thecleaning device 10. An operator may hold onto thehandle 90 to maneuver thecleaning device 10 relative to the enclosure. Thehandle 90 may include a first grippingportion 94 and a second grippingportion 98. InFIGS. 1-5 , the first grippingportion 94 is substantially D-shaped, and is positioned on thehousing 14 vertically above theinlet passage 22 andoutlet passage 26. The secondgripping portion 94 is substantially T-shaped, and projects outwardly from thehousing 14 forward of the first grippingportion 94 beyond the connection of the of theinlet passage 22 andtube 38. The twogripping portions handle 90 permit an operator to grip thecleaning device 10 with two hands and increase control of thecleaning device 10. In some constructions, thehandle 90 may be integrally formed on thehousing 14. - As shown in
FIG. 1 , thecleaning device 10 may include apump 102 connected to theoutlet passage 26. In the illustrated construction, anoutlet tube 106 connects theoutlet passage 26 and thepump 102 in fluid flow communication. Theoutlet tube 106 may include avalve 110 that selectively regulates fluid flow through theoutlet tube 106. - The
pump 102 creates a vacuum or negative pressure within thecleaning device 10 that generates a fluid flow through thecleaning device 10 that draws water from the enclosure into thecleaning device 10. Thepump 102 may include a conventional pump, such as a cylinder pump, a rotary pump, a centrifugal pump, a screw pump, or other similar pumps that generate a fluid flow or create a pressure differential. As shown inFIGS. 7-11 , thepump 102 may also include afaucet pump 114 having aventuri section 118. Thefaucet pump 114 may be connected to a faucet that provides a water flow. Thefaucet pump 114 directs the water flow from the faucet through theventuri section 118, which creates a vacuum or negative pressure within a portion of thefaucet pump 114. The vacuum draws the fluid flow through thecleaning device 10. - The
faucet pump 114 may also be used to reverse the fluid flow through thecleaning device 10 and refill an enclosure. Thefaucet pump 114 includes avalve 120 that directs fluid flow through thefaucet pump 114. As shown inFIGS. 8-9 thevalve 120 is disposed below theventuri section 118, and is movable between an open condition, in which water flows through thevalve 120 and out of thefaucet pump 114, and closed condition, in which thevalve 120 restricts the water flow and the water flow is directed back through theoutlet tube 106 toward thecleaning device 10. InFIG. 8 , thevalve 120 is open and theventuri section 118 of thefaucet pump 114 is generating a fluid flow from thecleaning device 10. InFIG. 9 , thevalve 120 is closed, and water flow from the faucet is directed toward thecleaning device 10.FIG. 10 illustrates a cross-sectional view of thevalve 120. Another example of a faucet pump is shown in U.S. Pat. No. 4,610,784, the entire contents of which are incorporated herein by reference. - In operation, the
cleaning device 10 removes particles, sediment, debris, and waste from fluid flowing through thecleaning device 10. Thepump 102 generates a fluid flow that draws fluid from an enclosure and flows through thecleaning device 10. The fluid flow through thecleaning device 10 flows along aflow path 122 through thecleaning device 10. InFIG. 5 , arrows indicate theflow path 122 through thecleaning device 10. As shown inFIG. 5 , theinlet passage 22 andoutlet passage 26 define at least a portion of the flow path for fluid through thehousing 14. Theflow path 122 generally flows from the enclosure, into theintake 46, through thetube 38, through theinlet passage 22 and theinlet aperture 30, through thereceptacle 18, through theoutlet aperture 34 andoutlet passage 26, and toward thepump 102. Thepump 102 may discharge the fluid flow into a drain, into a second receptacle, back into the original enclosure, into a second enclosure, onto the ground, or various other places. - The
cleaning device 10 draws fluid from the enclosure through thetube 38 and the fluid follows theflow path 122 into theinlet passage 22 of thehousing 14. Theinlet passage 22 empties the fluid into thereceptacle 18 through theinlet aperture 30 near the top of thereceptacle 18. In thereceptacle 18, particles, sediment, debris, and waste within the fluid may be gravitationally drawn downward toward thebottom surface 28. Theflow path 122 proceeds through thefilter 36. Thefilter 36 may include multiple apertures sized to permit fluid to pass through the filter, but may prevent particles, sediment, debris, and waste that is larger than the apertures from entering theoutlet passage 26. The particles that do not pass through thefilter 36 are collected in thereceptacle 18. - The
outlet passage 26 then receives the fluid flow through theoutlet aperture 34 near the top of thereceptacle 18 and theflow path 122 reenters thehousing 14. Theinlet passage 22 andoutlet passage 26 are both enclosed within thehousing 14. From theoutlet passage 26, theflow 122 path continues through theoutlet tube 106 and into thepump 102. Thevalve 110 may control fluid flow through theoutlet tube 106.FIG. 11 illustrates a cross-sectional view of thevalve 110. When thevalve 106 is open, fluid may flow through theoutlet tube 106 and cleaningdevice 10. When thevalve 106 is closed, fluid flow through theoutlet tube 106 and cleaningdevice 10. - The foregoing detailed description describes only a few of the many forms that the present invention can take, and should therefore be taken as illustrative rather than limiting. It is only the claims, including all equivalents that are intended to define the scope of the invention.
