[0021] This disclosure relates to fluid sprayers. Fluid sprayers can be used to spray a variety of fluids. Paints will be used as the primary example of the type of fluid to be sprayed, but it should be understood that this disclosure may also relate to spraying other types of fluids, such as paints, dyes, finishes, coatings, textures, and adhesives.
[0022] A spraying system, also known as a fluid atomizer, includes a pump module and a spray gun fluidly connected to the pump module. According to an aspect of this disclosure, the pump module includes a chassis configured to support the pump. An electric motor outputs rotary motion. A driver that converts the rotary output from the electric motor into a linear input to the pump is at least partially located in the chassis.
[0023] The pump module according to aspects of this disclosure includes a front cover mounted to a chassis. The front cover covers at least a portion of the drive. The front cover includes a side extension extending from at least one side of the front cover. The side extension extends further rearward than the rest of the front cover.
[0024] According to some disclosed aspects, the side extension of the front cover extends further rearward on a first side of the front cover than on a second side of the front cover opposite to the first side. The first side may be the top side of the front cover. The first side may be a lateral side of the front cover. In some examples, the side extension may be partially formed on both the top and lateral sides of the front cover. The side extension may include an angle between the top and lateral sides of the front cover.
[0025] According to some disclosed additional or alternative aspects, a gap may be formed between the chassis and the pump module's enclosure. The enclosure may cover various electrical components of the pump module, such as the motor and controller. The gap may be laterally positioned between the chassis and the enclosure, or it may be positioned elsewhere. Side extensions of the front cover may extend rearward to the enclosure to cover the gap. The side extensions may be aligned with the edges of the enclosure. The side extensions may be spaced outward from the chassis to align with the enclosure and cover the gap. The side extensions covering the gap prevent contaminants, such as falling paint particles, from entering.
[0026] According to the disclosed aspects, the pump module includes a housing that at least partially surrounds various components of the pump module. These include, for example, the motor, controller, and other components that can be covered by the housing. According to the disclosed aspects, a power cable for powering the electronic components of the pump module can be clamped between the chassis and the housing. The chassis and housing can engage with a ferrule on the power cable to position the power cable relative to other components of the pump module. The ferrule can engage with the chassis and / or the housing to secure the position of the power cable.
[0027] According to some disclosed aspects, the ferrule may extend into one or both of the housing and the chassis, the chassis and / or housing may extend into the ferrule, or a combination of such interfaces may clamp the power cable between the chassis and the housing. In some examples, the ferrule connects to one or both of the chassis and the housing at a tenon-groove interface.
[0028] According to some disclosed aspects, the pump module includes a transfer hose connecting the pump and the filter manifold. The pump can supply fluid to the filter manifold via the transfer hose. In a fluid atomizer including the pump module, a hose extending to the spray gun can extend between the filter manifold and the spray gun. The filter manifold can house a filter for filtering upstream coating on the spray gun.
[0029] The transfer hose can extend from inside the pump module's housing to the outside. The transfer hose can be guided through a channel, exiting from the inside of the pump module. The channel can be at least partially defined by the housing. Three of the four lateral sides of the channel can be defined by the housing, but it should be understood that this limitation is not present in all examples. The channel can be at least partially defined by the pump module's support structure. In various examples, the transfer hose is not secured in place by the housing. The transfer hose can pass through the housing without being engaged or secured by it.
[0030] According to aspects of this disclosure, the pump module includes a mounting plate configured to support a capacitor plate. The mounting plate can be installed inside the pump module. One or more capacitors can be mounted on the capacitor plate. The mounting plate can engage with the housing of an electric motor for installation within the pump module. In some examples, the mounting plate can engage with a connecting rod supporting the electric motor.
[0031] Figure 1A This is an isometric view of sprayer 10. Figure 1B This is a partial isometric view of the sprayer 10 of the cover 30, which is separated from the chassis 32. Figure 1C This is a partial top view of sprayer 10. Figures 1A-1C Let's discuss this together. The pump module 12, supply hose 14, water inlet pipe 16, and spray gun 18 of the sprayer 10 are shown in the figure. The module body 20, bracket 22, pump 24, filter manifold 26, protective cover 28, cap 30, chassis 32, module handle 34, transmission hose 36, and driver 38 of the pump module 12 are shown in the figure. The trigger 40, valve 42, gun handle 44, and nozzle head 46 of the spray gun 18 are shown in the figure.
[0032] It is understood that the sprayers in other embodiments may have different shapes. Figure 1A This includes directional arrows indicating the various forward, backward, left, right, upward, and downward directions. These directions can use synonyms, such as backward for rearward, upward for upward, downward for downward, and other options. Assuming these directions are portions of a three-axis Cartesian coordinate system radiating from the center of pump module 12, forward, backward, left, right, and up / down are relative directions along the respective axes of the three-axis Cartesian coordinate system. Right and left directions can also be referred to as lateral directions, forward and backward directions as longitudinal directions, and upward and downward directions as vertical directions.
[0033] The sprayer 10 is configured to receive spray fluid (e.g., paint, and other alternatives) from a reservoir (e.g., a tank) (not shown) via an inlet pipe 16. The sprayer 10 outputs paint through a nozzle of a spray gun 18. The nozzle is a portion of a nozzle head 46 inserted into the spray gun 18. The nozzle may be integrated into a tubing of the nozzle head 46. In some examples, the nozzle head 46 is a rotatable nozzle head 46. The rotatable nozzle head 46 can be rotated to reverse the flow direction of paint through the nozzle, to clear the nozzle in case of blockage. The rotatable nozzle head 46 can be replaced with various other rotatable nozzle heads 46, typically nozzles of different sizes and / or shapes, which produce different spray patterns (e.g., different fan sizes, spray shapes (conical, fan-shaped, etc.)).
[0034] Pump module 12 is configured to pressurize the fluid in the reservoir and output the pressurized fluid to spray gun 18. Spray gun 18 receives the spraying fluid via supply hose 14. Supply hose 14 can be a single hose or multiple hoses connected in series via fittings. Supply hose 14 is connected to pump module 12 at outlet 48. Outlet 48 is part of pump module 12.
[0035] Pump module 12 includes a module body 20. Pump module 12 includes a support 22. Support 22 includes a plurality of legs 50, which are placed on the ground to support module body 20. Support 22 may include at least two legs. Support 22 may include more than two legs 50. In the example shown, support 22 includes four legs 50 formed by two pipes. The entire module body 20 can be supported by support 22.
[0036] In the example shown, the support 22 includes a base plate 52. Legs 50 are connected to the base plate 52. The module body 20 can be connected to the base plate 52 for support. In various examples, the module body 20 can be supported on the ground by the base plate 52 and the legs 50. The module body 20 can be supported by the legs 50 via the base plate 52; however, it should be understood that not all examples are so restrictive.
[0037] Pump module 12 includes pump 24. Pump 24 is configured to draw paint from a reservoir and pressurize it. Pump 24 is configured to drive the pressurized paint to spray gun 18 for spraying onto a target substrate. Pump 24 may be a piston pump, which includes a piston that reciprocates within cylinder 54 to pressurize paint or other spray fluids. Pump 24 may be detachably mounted to module body 20.
[0038] Pump 24 can be connected to other parts of pump module 12 via a static interface and a dynamic interface. The static interface holds pump 24 on the body 20. The dynamic interface drives the piston of pump 24 in a reciprocating motion. In the example shown, the static interface is formed between pump 24 and module body 20. Pump 24 may be at least partially disposed within mounting cavity 56 of module body 20 and mounted to module body 20.
[0039] Pump module 12 includes a filter manifold 26. The filter manifold 26 receives the output paint from pump 24 via a transfer hose 36. The transfer hose 36 extends between the outlet of pump 24 and the inlet of filter manifold 26. A filter is housed within filter manifold 26, filtering the paint before it is output through outlet 48. Outlet 48 may be an accessory to filter manifold 26. Such an accessory is connected to supply hose 14. Thus, paint can flow from pump 24 to filter manifold 26 via transfer hose 36, and then from filter manifold 26 to spray gun 18 via supply hose 14.
[0040] The pump module 12 includes a chassis 32 that supports other components of the pump module 12. The chassis 32 can be mounted on a bracket 22. For example, the chassis 32 can be mounted on the base plate 52 of the bracket 22. The chassis 32 can form the frame of the module body 20.
[0041] The chassis 32 may be formed of metal. The chassis 32 may be formed of multiple pieces of metal. The chassis 32 may structurally support the electric motor, pump 24, shroud 28, cover 30, filter manifold 26, and various other components of the pump module 12. The chassis 32 may include at least part or all of the drive 38 and can therefore be considered to form a drive housing. The drive 38 converts the output of the rotary motion of the motor from the pump module 12 into linear reciprocating motion operating the pump 24, such as the reciprocating motion of the piston of the pump 24.
[0042] Pump module 12 includes a housing 28. Housing 28 forms part of module body 20. Housing 28 can enclose various other components of pump module 12 inside pump module 12. Housing 28 can be formed as a single piece. Housing 28 can be formed of polymer, and other options. Housing 28 is a hollow structure that can accommodate motor, controller and / or other components of pump module 12.
[0043] In the example shown, the shield 28 is a single, integral part. In this example, the shield 28 is not formed from multiple parts (e.g., a double-shell configuration). However, it should be understood that in some examples, the shield 28 may be formed from multiple parts, such as a double-shell configuration. In some examples, the shield 28 may be formed of metal. The shield 28 may be mounted to the chassis 32.
[0044] Pump module 12 also includes a cover 30. Cover 30 may be mounted on the front side of pump module 12. Cover 30 may be referred to as a front cover. Cover 30 may form the front outward surface of module body 20. Cover 30 may be attached to chassis 32. Cover 30 may at least partially cover a portion of drive 38. Cover 30 may extend over a portion of drive 38 to surround that portion of drive 38, for example, covering drive 38 to prevent contaminants from reaching drive 38 and protecting the user from accidental contact with drive 38 during operation.
[0045] Pump module 12 includes a module handle 34. At least a portion of the module handle 34 may be formed from the same metal portion forming the chassis 32. In various examples, the module handle 34 is directly connected to the chassis 32. The module handle 34 may be separately formed from and connected to the chassis 32, for example, by one or more fasteners (e.g., bolts or other alternatives). The module handle 34 extends from the chassis top side 58 of the chassis 32. Pump module 12 can be carried by a user grasping the module handle 34 and carrying the pump module 12 through the module handle 34.
[0046] The cover 30 includes a front cover side 60, a top cover side 62, a lateral cover side 64a, and a lateral cover side 64b. In various examples, the lateral cover side 64a is on the right side of the pump module 12, and the lateral cover side 64b is on the left side of the pump module 12.
[0047] The cover 30 includes a side extension 66. The side extension 66 is a portion of the cover 30 that extends beyond the rest of the cover 30. In the example shown, the side extension 66 extends rearward relative to the rest of the cover 30.
[0048] The cover 30 includes a cover base 68 formed by the cover edge 70 of the cover 30. The cover base 68 faces the chassis 32, on which the cover 30 is mounted. A side extension 66 extends rearward from the cover base 68. The side extension 66 extends outward from the cover base 68 to extend further rearward than the cover base 68.
[0049] In this example, the lid 30 is laterally asymmetrical. In this example, the lateral side 64a of the lid includes a lateral extension 66, while the lateral side 64b of the lid does not include any lateral extension 66. It is understood, however, that not all examples are so restrictive. In some examples, both the lateral side 64a and the lateral side 64b of the lid may include lateral extensions. In one such example, the lateral extension 66 may be longer than the relatively shorter lateral extension on the lateral side 64b of the lid.
[0050] Window 81 is formed by chassis 32. When cover 30 is removed, window 81 exposes actuator 38. Window 81 is formed by an extension 72 of chassis 32 that extends longitudinally forward. Chassis 32 may define drive cavity 83, in which a portion of actuator 38 is disposed. Extension 72 may form one or more sides of drive cavity 83. For example, extension 72 may define a top side, lateral side, bottom side, etc., of drive cavity 83. In the illustrated example, window 81 opens into drive cavity 83. Extension 72 extends forward from other portions of chassis 32.
[0051] In the example shown, chassis 32 includes a base portion 82 (in... Figure 4A and Figure 4B The upper portion 84 is the best visible part of the chassis 32. The base portion 82 can be connected to the bracket 22 to connect the chassis 32 to the bracket 22. The upper portion 84 extends vertically from the base portion 82. The drive cavity 83 can be formed in the upper portion 84. The extension 72 can extend from the wall 86 of the upper portion 84. The upper portion 84 and the base portion 82 can be formed integrally, such that the chassis 32 is formed as a single component. In some examples, the extension 72 can be formed separately from the wall 86 and connected to the wall to form the chassis 32.
[0052] The cover 30 partially or completely surrounds the extension 72 of the chassis 32 (e.g., the top, bottom, and lateral sides of the extension 72), forming a window 81. The cover 30 can be mounted on the chassis 32 such that the chassis 32 is received at least partially within the cover 30. Therefore, the cover 30 can overlap with the chassis 32.
[0053] Along the lateral extension 66, the overlap between the cover 30 and the chassis 32 is greater than that of the rest of the cover 30 extending rearward from the front side 60. Only a single lateral extension 66 may exist as part of the cover 30, but it should be understood that not all examples are so limited.
[0054] The chassis 32 includes a chassis lateral side 74 and a chassis top side 58. Between (or formed by) the chassis lateral side 74 and the chassis top side 58 is a chassis angle 76. In various examples, the chassis lateral side 74 and the chassis top side 58 may be formed by or at least partially by an extension 72 that at least partially defines a drive cavity 83.
[0055] The chassis angle 76 is curved between the chassis lateral side 74 and the chassis top side 58. The chassis lateral side 74 can be considered as the lateral side forming the chassis 32. The side extension 66 also forms an extension angle 78 between the cover lateral side 64a and the cover top side 62. The extension angle 78 can be curved between the laterally oriented cover lateral side 64a and the longitudinally oriented cover top side 62. The extension angle 78 can be considered as including a portion of the cover lateral side 64a (the right side in this embodiment) and a portion of the cover top side 62. The extension angle 78 is configured to extend and cover the chassis angle 76.
[0056] In the illustrated example, the side extension 66 extends further rearward on one side of the cover 30 than on the opposite side of the cover 30. The side extension 66 may extend further rearward on the cover lateral side 64a than on the opposite cover lateral side 64b. The side extension 66 may additionally or alternatively extend further rearward on the cover top side 62 than on the bottom vertical side of the cover 30 (opposite to the cover top side 62). The side extension 66 may be considered to extend further rearward on a first side and / or a third side of the cover 30, wherein the first side is located on the opposite side of the second side of the cover 30, and the third side is located on the opposite side of the fourth side of the cover 30. For example, the first side may be formed by the cover lateral side 64a, and the third side may be formed by the cover top side 62.
[0057] The cover 30 can be secured to the chassis 32. The cover 30 can be mounted to the chassis 32 using fasteners 80, or other alternatives. The fasteners 80 can be threaded fasteners (such as screws, bolts, etc.) that extend through respective holes in the cover 30 and are screwed into threaded holes in the chassis 32 to secure the cover 30 to the chassis 32.
[0058] In the illustrated example, a gap 90 is provided between the chassis 32 and the protective cover 28, which is mounted on the chassis 32. The gap 90 is located on the lateral side of the module body 20. In the illustrated example, the gap 90 is located on the right side of the module body 20. In the illustrated example, the gap 90 is formed between the outer side of the chassis 32 and the inner side of the protective cover 28. The gap 90 can open longitudinally and expose the interior of the module body 20 within the protective cover 28. The gap 90 can be a lateral gap between the protective cover 28 and the chassis 32.
[0059] Gap 90 allows wet or dry paint sprayed from spray gun 18 to enter, if the side extension 66 of non-cap 30 extends to cover gap 90. Therefore, the asymmetrical side extension 66 can cover a specific gap 90. In this example, gap 90 does not appear on the other side (left side) of pump module 12.
[0060] Figure 2A This is a partial top view of sprayer 10. Figure 2A Cover 30 is omitted to show a closer view of gap 90. Figure 2BThis is a partial top view of the sprayer 10, showing the cover 30 mounted on the chassis 32.
[0061] A gap 90 is formed between the chassis 32 and the shield 28. In the illustrated example, various internal components of the sprayer 10 are exposed through the gap 90. These exposed internal components may be electronic. In the illustrated example, a portion of the controller 88 is visible through the gap 90. The controller 88 is configured to control the electrical system of the pump module 12. Contact between wet spray fluid and the electrical components of the controller 88 should be avoided. The side extension 66 extends and covers the gap 90, preventing wet fluid from entering the interior of the module body 20, thus helping to avoid contact with wet fluid.
[0062] The controller 88 can be any desired configuration for controlling the operation of electrical components (e.g., motors and other components) of the pump module 12, and may include control circuitry (e.g., one or more processors, microprocessors, controllers, digital signal processors (DSPs), application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), graphics processing units (GPUs), modular systems (SOMs), or other equivalent discrete or integrated logic circuits) and computer-readable storage.
[0063] Controller 88 is configured to store executable code, implement functions, and / or process instructions. Controller 88 is configured to perform any of the functions discussed herein, including controlling the operation of any components mentioned herein. Controller 88 can be any suitable configuration for controlling the operation of electrical components, collecting data, processing data, etc., and controller 88 may include hardware, firmware, and / or stored software. Controller 88 can be of any type suitable for operation according to the techniques described herein. It is understood that controller 88 can be mounted wholly or partially on one or more circuit boards. In some examples, controller 88 can be implemented as multiple discrete circuit sub-components.
[0064] The cover 30 is installed such that the chassis 32 is at least partially disposed within the cover 30. In various examples, the edge 70 of the cover 30 may extend rearward toward the leading edge of the frame 32 and completely surround the chassis 32. The side extension 66 extends further rearward than the rest of the cover 30.
[0065] In the example shown, the side extension 66 is laterally spaced outside the chassis 32. The cover lateral side 64a is laterally spaced outside the chassis lateral side 74, such that a gap 92 is provided between the two. The side extension 66 is spaced apart from the chassis lateral side 74, allowing the side extension 66 to extend outward to cover the gap 90 formed between the chassis 32 and the cover 28.
[0066] In the example shown, the gap 90 between the chassis 32 and the cover 28 extends laterally. A side extension 66 is laterally disposed outside the lateral side 74 of the chassis, positioning the cover 30 to overlap the gap 90 longitudinally. The side extension 66 may extend further to overlap the gap 90 laterally and / or vertically.
[0067] The distal end 94 of the side extension 66 is the end of the side extension away from the base 68 of the cover body 96. In the illustrated example, the distal end 94 is formed by an edge 70. In the illustrated example, the distal end 94 of the side extension 66 is the portion of the side extension 66 that extends furthest in the rearward direction.
[0068] The side extension 66 may be aligned with the shroud 28 to cover the gap 90. In some examples, the distal end 94 of the side extension 66 may be aligned with the shroud edge 98 of the shroud 28. The edge 70 on the side extension 66 may be aligned with the shroud edge 98. The shroud edge 98 is spaced apart from the chassis 32 by the gap 90. The alignment of the side extension 66 with the shroud edge 98 minimizes the size of any opening in the gap 90 by preventing the formation of lateral or longitudinal openings between the shroud edge 98 and the side extension 66. This longitudinal overlap between the side extension 66 and the shroud 28 can therefore inhibit the absorption of contaminants through the gap 90.
[0069] Figure 3 This is the isometric rear view of the cover 30. Figure 3 The view shows the interior and rear side of the cover 30. The front side 60, top side 62, lateral side 64a, and lateral side 64b of the cover 30 are shown. The cover 30 includes a cover body 96, a side extension 66, and a notch 100. The cover 30 includes a cover base 68 formed by an edge 70 of the cover 30. The edge 70 extends to the rear side of the cover 30 to define an opening into the cover 30. The edge 70 may form the edge of the cover base 68 and the side extension 66. The edge 70 may form the notch 100.
[0070] In the example shown, the cover body 96 is configured to extend and surround one or more components of the pump module 12. The cover body 96 may cover the window 81 of the chassis 32. A side extension 66 extends from the cover body 96. The side extension 66 extends longitudinally from the cover body 96. In the example shown, the side extension 66 extends rearward from the cover body 96.
[0071] Edge 70 extends around the open end of cover 30. Cover base 68 of cover 30 is formed by a portion of edge 70. Cover base 68 forms the end of cover body 96. Side extension 66 extends rearward relative to cover base 68. Side extension 66 is configured to extend toward shield 28 closer to shield 28 than cover body 96 of cover. Side extension 66 extends closer to shield 28 than cover base 68 of cover 30. Side extension 66 extends to distal end 94, longitudinally separated from cover base 68 of cover 30. Distal end 94 may form a portion of side extension 66 adjacent to shield 28.
[0072] The cover 30 includes a notch 100. The notch 100 extends into the cover body 96. In the illustrated example, the notch 100 extends forward from the cover base 68 of the cover body 96. The notch 100 extends forward, while the side extension 66 extends rearward. In this example, the notch 100 is formed on the cover 30 on the side opposite to the side extension 66, which is at least partially on the top side 62 of the cover, and the notch 100 is formed on the bottom side of the cover 30.
[0073] The notch 100 is configured to receive a portion of the chassis 32 on which the cover 30 is mounted. The notch 100 is formed by the edge 70 of the cover 30. The edge 70 forms a side extension 66, wherein the edge 70 is longer along the side extension 66 relative to the rest of the edge 70. In the example shown, the cover 30 is configured such that the top side 62 of the cover extends further rearward than the bottom side of the cover 30, forming the notch 100 on the bottom side.
[0074] Figure 4A It is an isometric view showing a portion of the sprayer 10 with the protective cover 28 installed. Figure 4B This is an isometric cross-sectional view showing a portion of the sprayer 10 within the shield 28, separated from the chassis 32. The internal portion of the pump module 12 is shown below. Figure 4A and Figure 4B As shown.
[0075] A portion of the controller 88 is shown inside the pump module 12. The controller 88 is covered by a housing 28, which is mounted to the chassis 32. A power cord 102 extends into the pump module 12. The power cord 102 is configured to provide power to components of the sprayer 10. The power cord 102 can be connected to the controller 88. The power cord 102 can be a standard wire with a plug at its distal end that can be connected to a power outlet to provide power to the controller 88, thereby driving the electric motor via the driver 38 to operate the pump 24.
[0076] Power cord 102 is clamped between chassis 32 and housing 28 to secure it. Specifically, chassis 32 is positioned in front of pump module 12 relative to power cord 102, and housing 28 is positioned behind pump module 12. Clamping power cord 102 between housing 28 and chassis 32 maintains its position and orientation relative to these components. As shown, power cord 102 is clamped, and conductor 104 can extend from the sheath of power cord 102 to components of pump module 12 within the pump module 12. Power cord 102 is configured to be non-removable once clamped.
[0077] The power cord 102 includes a collar 106. The collar 106 is the portion of the power cord 102 that is clamped between the chassis 32 and the housing 28. The collar 106 can contact both the chassis 32 and the housing 28 to clamp between them. The collar 106 is connected to both the chassis 32 and the housing 28.
[0078] The collar 106 can form an amplified portion of the power line 102 relative to the portion of the power line 102 that is close to the collar 106 and outside the interior of the pump module 12. The collar 106 can form an enlarged sleeve. The wire 104 can extend from the outside of the pump module 12 through the collar 106 into the interior of the pump module 12.
[0079] The collar 106 includes a cable interface 108 that can connect to the shield interface 110 of the housing 28. The cable interface 108 may also additionally or alternatively connect to the chassis interface 112 of the chassis 32. This interface may be a tongue-and-groove type to help secure the power cable 102 and prevent it from being pulled out of its clamped position. As shown, the collar 106 includes a groove into which respective protrusions of the chassis 32 and / or the housing 28 extend. The groove 114 forms the cable interface 108.
[0080] In the illustrated example, the shield 28 includes a shield protrusion 116 forming a shield interface 110. The shield protrusion 116 is formed as a shelf that can extend into a groove 114. In the illustrated example, the shield protrusion 116 at least partially wraps around a collar 106. The shield protrusion 116 can extend into the rear side of the collar 106 and into the groove 114 on one or both sides of the collar 106.
[0081] In some examples, the chassis interface 112 is formed by the surface of the chassis 32. The collar 106 can be pressed against the surface of the chassis 32 by the cover 28. In some examples, the chassis 32 includes a protrusion extending into a groove 114 for engagement with the collar 106 within the groove 114. However, it is understood that not all examples are so limited. In some examples, the chassis 32 can abut against the collar 106 without having a protrusion extending into the groove 114.
[0082] In the example where both the housing 28 and the chassis 32 include protrusions, the respective protrusions of the housing 28 and the chassis 32 may be at the same vertical level. Therefore, one or more protrusions of the housing 28 and one or more protrusions of the chassis 32 may extend into the same groove 114 forming the cable interface 108. However, it will be understood that in various other examples, the protrusions forming the housing interface 110 and the chassis interface 112 may be at different vertical levels and extend into different grooves of the collar 106.
[0083] While the ferrule 106 can be configured to receive portions of the chassis 32 and the housing 28, it is understood that not all examples are so limited. In some examples, the chassis interface 112 can be formed as one or more protrusions, and the chassis interface 112 and the housing interface 110 can be formed as slots. In some examples, the chassis interface 112 can be formed as a combination of slots and protrusions, wherein one of the housing interface 110 and the chassis interface 112 is formed as a slot to receive a protrusion of the cable interface 108, and the other of the housing interface 110 and the chassis interface 112 is formed as a protrusion to be received by the slot of the cable interface 108. Thus, in various examples, the ferrule 106 can extend into one, the other, or both of the chassis 32 and the housing 28 to mount the power cord 102.
[0084] In various examples, the collar 106 may receive or be received by one of the housing 28 and the chassis 32 while abutting against the other of the housing 28 and the chassis 32. For example, one of the housing 28 and the chassis 32 may include a protrusion extending into a groove 114 of the collar 106. The collar 106 may be securely held therein by the chassis 32 and the housing 28 to secure the power cord 102. The collar 106 may abut against the other of the chassis 32 and the housing 28, for example, against the plane of the other of the chassis 32 and the housing 28.
[0085] The collar 106, clamped between the chassis 32 and the housing 28, offers significant advantages. The power cord 102 is secured by clamping its position relative to components inside the pump module 12. This configuration prevents damage to internal connections caused by the power cord 102, such as from pulling or agitating it. The clamping of the power cord 102 between the housing 28 and the chassis 32 facilitates assembly and reduces the number of parts, as the power cord 102 is directly secured to a portion of the module body 20.
[0086] In this example, the power cord 102 does not pass through the portion of bracket 22. The power cord 102 does not pass through the base plate 52 of the bracket. The power cord 102 is located between and directly secured to the housing 28 and the chassis 32. This configuration provides a simpler configuration, is easier to assemble, and provides a secure hold for the power cord 102.
[0087] Figure 5A This is a partial isometric view of pump module 12, showing the rear of pump module 12. Figure 5B This is a rear view showing a portion of the pump module 12. As shown, a transfer hose 36, extending between the pump 24 and the filter manifold 26, extends out from within the housing 28 as the pump 24 and filter manifold 26 move between them. Specifically, the transfer hose 36 extends from the interior of the pump module 12 through a channel 118. In several examples, the channel 118 completely surrounds the transfer hose 36 because the transfer hose 36 extends through the channel 118.
[0088] In the example shown, the shield 28 defines the top side and two lateral sides (left and right) of the channel 118. The bracket 22 defines the bottom side of the channel 118. In this way, the channel 118 surrounds the transmission hose 36 on its top, bottom, left, and right sides. The top, left, and right sides of the channel 118 are formed by a shield notch 120 in the shield 28. The shield notch 120 is U-shaped in the example shown, however, it can be understood to be of various other shapes. In the example shown, the bottom side of the channel 118 is defined by the bracket 22, and the shield 28 defines the other sides of the channel 118.
[0089] The bottom side of channel 118 is formed by the base plate 52 of bracket 22. The legs 50 of bracket 22 can be attached to the base plate 52. In various examples, a chassis 32 is mounted on the base plate 52 to connect to bracket 22. For example, the base portion of chassis 32 can be attached to the base plate 52. In some examples, bracket 22 includes two tubes forming four legs 50, which are connected together at their midpoints to the base plate 52 by being individually connected (e.g., by welding).
[0090] As shown, the channel 118 surrounds but does not contact the transfer hose 36. The transfer hose 36 is not secured in place by the shield 28. The channel 118 can protect the transfer hose 36. The transfer hose 36 is not clamped by the shield 28 and / or the bracket 22, but these structures can still surround and help protect the transfer hose 36. Therefore, the transfer hose 36 maintains flexibility between the pump 24 and the filter manifold 26.
[0091] Figure 6 This is an enlarged isometric view showing the interior of pump module 12. For clarity, the protective cover 28 has been removed. Figure 7A This is the first isometric view of mounting plate 122. Figure 7BThis is the second isometric view of mounting plate 122. Figures 6-7B Discuss together. The cover 28 is attached to the back of the chassis 32 by fasteners such as bolts that pass through a portion of the cover 28 and into threaded holes in the chassis 32.
[0092] Mounting plate 122 is disposed inside pump module 12. Capacitor plate 124 is mounted on mounting plate 122. Capacitor plate 124 may be a circuit board, such as a printed circuit board. At least one capacitor 126 is mounted on capacitor plate 124. This capacitor plate 124 may only be needed in some areas, making it undesirable to integrate capacitor 126 into the controller 88 of all manufactured units. Capacitor plate 124 may be installed in areas where such capacitor 126 is needed.
[0093] Mounting plate 122 facilitates modular mounting of capacitor plate 124 for embodiments requiring such capacitors 126. Mounting plate 122 is mounted on the top side of motor 127 and can contact the cylindrical housing 128 of motor 127. In the illustrated example, mounting plate 122 is vertically positioned above motor 127. Mounting plate 122 can be directly vertically positioned above motor 127. In the illustrated example, mounting plate 122 is positioned above motor 127 such that mounting plate 122 radially overlaps motor 127 with respect to the axis of rotation of the rotor of motor 127. Mounting plate 122 can be formed of polymer, or other alternatives.
[0094] In the example shown, connecting rod 130 assists in supporting motor 127 within pump module 12. Connecting rod 130 helps secure motor 127 within pump module 12. Connecting rod 130 can connect to chassis 32. Connecting rod 130 can connect to an end of motor 127 opposite to the end of motor 127 facing chassis 32. Connecting rod 130 can connect to an end of motor 127 opposite to the end of motor 127 that provides rotational output to drive 38. Connecting rod 130 can extend longitudinally across motor 127.
[0095] Mounting plate 122 at least partially surrounds connecting rod 130. In the illustrated example, connecting rod 130 may extend entirely longitudinally through mounting plate 122. In some examples, connecting rod 130 extends outward from mounting plate 122 in a rearward longitudinal direction. In some examples, connecting rod 130 may extend outward from mounting plate 122 in both rearward and forward longitudinal directions.
[0096] In the example shown, a portion of the mounting plate 122 extends between the connecting rod 130 and the housing 128 of the motor 127. A portion of the mounting plate 122 may be directly disposed between the connecting rod 130 and the housing 128 of the motor 127. A portion of the mounting plate 122 may extend longitudinally forward beyond the motor 127. A portion of the mounting plate 122 may extend longitudinally forward from the end face of the housing 128.
[0097] Mounting plate 122 includes mounting body 132, handle 134, lock 136, receiver 138, and plate interface 140. Mounting body 132 is the main body portion of mounting plate 122. Mounting body 132 includes plate portion 142 and mounting portion 144. Plate portion 142 and mounting portion 144 are perpendicularly spaced. In the illustrated example, receiver 138 is formed as a notch between mounting portion 144 and plate portion 142.
[0098] In the illustrated example, lock 136 is formed on mounting portion 144. Lock 136 may include a latch 146 that can bend as mounting plate 122 slides longitudinally relative to cylindrical housing 128 of motor 127, and then spring back inward after passing the front end of housing 128 of motor 127, such that the end of the latch engages with the front side of housing 128 to lock mounting plate 122 in place. The latch 146 of lock 136 is configured to be manually pressed (e.g., by a user's finger) to disengage from the front side of motor 127 to allow mounting plate 122 to slide relative to motor 127 for removal.
[0099] In various examples, a portion of the chassis 32 may be received by the mounting plate 122. The chassis 32 may extend into the receiver 138 of the mounting plate 122, while the mounting plate 122 is mounted in the pump module 12. The receiver 138 may be formed as a recess, disposed between the mounting portion 144 and the plate portion 142 of the mounting plate 122.
[0100] The plate portion 142 of the mounting plate 122 is configured to support the capacitor plate 124. A plate interface 140 is formed on one side of the plate portion 142. The plate interface 140 is formed on the side of the plate portion 142 oriented away from the motor 127, and the mounting plate 122 is mounted thereon. The capacitor plate 124 is mounted to the mounting plate 122 at the plate interface 140. The plate interface 140 may have holes, such as threaded holes, threaded protrusions, combinations thereof, or other structures connecting the mounting plate 122 and the capacitor plate 124.
[0101] A handle 134 is formed on the plate portion 142. The handle 134 is configured to connect to the connecting rod 130 to mount the mounting plate 122 onto the connecting rod 130. In the example shown, the handle 134 includes a locking finger 148 and a positioner 150. The locking finger 148 is configured to at least partially wrap around the connecting rod 130 to grip the connecting rod 130. The positioner 150 is configured to connect to the connecting rod 130 and can provide support between the connecting rod 130 and the plate portion 142. The positioner 150 may include a curved base in which the curved exterior of the connecting rod 130 is disposed. The positioner 150 can be placed on the connecting rod 130. The positioner 150 may be disposed on the top side of the connecting rod 130, while the locking finger 148 wraps around the bottom side of the connecting rod 130.
