[0008] This disclosure relates generally to battery-powered fluid spraying devices. The battery-powered sprayer can spray various liquids such as paint, varnish, sealant, or other types of coatings. A battery powers an electric motor, which drives a pump. The pump draws pressurized fluid from a reservoir to a spray gun. The fluid is expelled under pressure from a nozzle in the spray gun as a liquid spray mist. The battery is mounted at the bottom of the fluid sprayer to protect it from liquid particles that do not adhere to the target surface and can be referred to as "excess." The liquid particles fall through the atmosphere surrounding the fluid sprayer, and the battery is protected from the excess by parts of the fluid sprayer.

[0009] Fig. 1A is a side-by-side block diagram of the spray system 10. Fig. 1B is a rear block diagram of the fluid spray device 12. Fig. 1A and Fig. 1B are explained together. The spray system 10 comprises a fluid spray device 12, a reservoir 14, a hose 16, and a spray gun 18. The fluid spray device 12 comprises a spray body 20, a stand 22, a pump 24, a motor 26, a drive 28, a battery mounting bracket 30, and a battery 32. The spray device body 20 comprises a bottom 34. The stand 22 comprises support elements 36. The pump 24 comprises a pump body 38 and a piston 40. The battery mounting bracket 30 comprises edges 42 that define a mounting opening 44 and a bottom opening 46. The battery 32 comprises a top 48, a bottom 50, longitudinal ends 52a, 52b, and side surfaces 54a, 54b. The spray gun 18 comprises a pistol grip 56, a trigger 58, and a nozzle 60.

[0010] The fluid spray device 12 is configured to draw a spray liquid from the reservoir 14 and deliver the spray liquid under pressure to the spray gun 18, where it is sprayed by the spray gun 18. The spray liquid can be, for example, a coating such as paint, varnish, sealant, or another type of coating. The fluid spray device 12 can be an airless spray device because it does not rely on compressed air to shape or atomize the liquid spray jet. Instead, the pump 24 generates sufficient pressure to cause the nozzle 60 to atomize the liquid into the liquid spray jet.

[0011] The stand 22 supports other components of the spraying device 12 relative to a support surface, such as a floor or the ground. The stand 22 consists of one or more support elements 36 that extend vertically relative to the spraying device body 20 and contact the support surface. The support elements 36 may consist of legs, rails, etc. The support elements 36 are shown extending from the spraying device body 20 near a front end of the spraying device body 20 (the side with the pump 24) and a rear end of the spraying device body 20 opposite the front end. However, it is understood that some examples of the stand 22 include support elements 36 that extend only near the rear end of the spraying device body 20.For example, the support elements 36 can comprise a vertically extending section extending from the spray device body 20 and a horizontal section contacting the support surface. In some embodiments, the stand 22 can include one or more wheels contacting the ground surface to facilitate moving the fluid spray device 12 on a construction site.

[0012] The spray device body 20 is supported vertically above the support surface by the stand 22. The spray device body 20 supports and can enclose one or more components of the fluid spray device 12. The pump 24 is supported by the spray device body 20. The pump 24 can be detachably connected to the spray device body 20, allowing it to be removed from the fluid spray device 12 for maintenance, storage, replacement, etc. The pump body 38 is connected to the spray device body 20, for example, by a clamp or a threaded connection, among other options. The piston 40 is located at least partially within the pump body 38 and is configured to move back and forth to pump the spray fluid from the reservoir 14 to the spray gun 18. The pump 24 can have any shape suitable for pumping the fluid under pressure to the spray gun 18 for spraying.In some embodiments, the pump 24 is a double positive displacement pump, so that the pump 24 discharges fluid both during an upward or suction stroke of the piston 40 and during a downward or pressure stroke of the piston 40.

[0013] Motor 26 is functionally connected to pump 24 to cause pumping through pump 24. Motor 26 is located within the sprayer body 20. Motor 26 is an electric motor. Motor 26 can be, for example, a brushed or brushless DC motor or an AC induction motor, among other options. Motor 26 is functionally connected to piston 40 to drive a reciprocating motion of piston 40 along pump axis AA, thus causing pumping through pump 24. Pump axis AA can be, among other options, a vertical axis. In the example shown, the motor 26 and the drive 28 cause a reciprocating movement of the piston 40. The drive 28 is at least partially located inside the spray device body 20 and is configured to convert a rotational power of the motor 26 into a linear reciprocating movement of the piston 40.The drive 28 can have any form suitable for converting the rotational power into a linear reciprocating motion, for example a cam, a Scotch yoke or an eccentric crank.

[0014] The battery mounting bracket 30 is supported by the stand 22. For example, part of the stand 22 may extend below the sprayer body 20 and between the battery mounting bracket 30 and the sprayer body 20. In some embodiments, the battery mounting bracket 30 may be directly connected to the sprayer body 20, so that the battery mounting bracket 30 is supported by the stand 22 above the sprayer body 20. The battery mounting bracket 30 extends from a bottom surface 34 of the sprayer body 20. The battery mounting bracket 30 hangs vertically below the bottom surface 34 of the sprayer body 20, so that the battery mounting bracket 30 is located directly between the sprayer body 20 and the support surface. The battery mounting bracket 30 is held by support elements 36 of the stand 22.The battery mounting bracket 30 can be arranged laterally between the support elements 36 of the stand 22 and / or longitudinally between the support elements of the stand 22. The battery mounting bracket 30 can be oriented so that the mounting opening 44 is located laterally and / or longitudinally between the support elements 36 to facilitate the installation and removal of the battery 32. The battery mounting bracket 30 is positioned below the spray device body 20 in such a way that the latter protects the battery mounting bracket 30 from falling liquid particles during the spraying process. The edges 42 of the battery mounting bracket 30 form a cavity in which the battery 32 is mounted to electrically connect it to the motor 26.The edges 42 extend beyond the sides of the battery 32 and vertically below the top edge of the battery 32 and away from the spray device body 20 to protect the battery 32 from falling liquid splashes like an umbrella or awning.

[0015] The battery 32 is supported by a stand 22. The battery 32 is connected to the stand via the battery mounting bracket 30. The battery 32 is directly connected to the battery mounting bracket 30 and hangs vertically from the battery mounting bracket 30 away from the sprayer body 20. The battery 32 is configured to supply power to the motor 26 to operate the pump 24. The battery 32 can be a lithium battery or another type of battery to provide the electrical energy. The battery 32 is located on the underside of the fluid sprayer 12 and spaced apart from the underside 34 of the sprayer body 20. The battery 32 is positioned vertically between the support surface and the sprayer body 20. The battery 32 can be positioned laterally and / or longitudinally between the support elements 36 that form the stand 22.

[0016] The battery 32 can be slidably connected to the battery mounting bracket 30. The battery 32 can be connected to the battery mounting bracket 30 by sliding it through the mounting opening 44 onto the battery mounting bracket 30, thus engaging it with the bracket. The battery 32 can be removed from the battery mounting bracket 30 by sliding it away from the bracket and out through the mounting opening 44. Part of the battery 32 hangs vertically below the battery mounting bracket 30 through the lower opening 46. The battery mounting bracket 30 is configured such that the battery 32 can be removed from the fluid spray device 12 through an opening that is at least partially defined by support elements 36.In the example shown, the battery mounting bracket 30 is configured such that the battery 32 is removed through a rear opening between the support elements 36 relative to the fluid spray device 12. During installation, the battery 32 is moved radially in the direction of the pump axis AA. During removal, the battery 32 is moved radially away from the pump axis AA. The rear opening is positioned opposite the front opening, which is blocked by the pump 24, the pump 24 being attached to the spray device body 20.

[0017] The battery 32 is enclosed in the chamber, which is at least partially bounded by the edges 42 of the battery mounting bracket 30. The top surface 48 of the battery 32 is completely located within the chamber of the battery mounting bracket 30. The battery 32 can be mounted on the battery mounting bracket 30 such that only the top surface 48 of the battery 32 is in contact with the battery mounting bracket 30. The top surface 48 of the battery 32 is completely enclosed and covered by the battery mounting bracket 30. The battery 32 hangs vertically from the battery mounting bracket 30, extending away from the spray device body 20. Thus, the battery mounting bracket 30 is located directly between the spray device body 20 and the battery 32. The longitudinal ends 52a, 52b of the battery 32 project through the lower opening 46 of the battery mounting bracket 30, so that each of the longitudinal ends 52a, 52b is exposed outside the mounting chamber.The longitudinal end 52a is aligned with the mounting opening 44, but the mounting opening 44 is spaced longitudinally from the longitudinal end 52a, so that the longitudinal end 52a is covered by the top of the battery mounting bracket 30. The longitudinal end 52a does not touch the battery mounting bracket 30. In some embodiments, each longitudinal end 52a, 52b is spaced from the battery mounting bracket 30 and does not touch it. Each of the longitudinal ends 52a, 52b is partially located within the chamber defined by the battery mounting bracket 30. The side faces 54a, 54b of the battery 32 extend through the lower opening 46 of the battery mounting bracket 30 and vertically out of the battery chamber.

[0018] The side surfaces 54a, 54b extend out of the chamber of the battery mounting bracket 30, such that the side surfaces 54a, 54b are partially covered by the battery mounting bracket 30 and partially exposed outside of the battery mounting bracket 30. The side surfaces 54a, 54b are each partially vertically overlapped by the lateral edges 42. The side surfaces 54a, 54b are spaced from the walls of the battery mounting bracket 30, such that neither side surface 54a, 54b touches the battery mounting bracket 30.

[0019] The battery 32 is spaced apart from the edges 42 of the battery mounting bracket 30. Air gaps are formed between the side surfaces 54a, 54b and the edges 42 of the battery mounting bracket 30. In some embodiments, an air gap is formed between the longitudinal end 52b and the rear edge 42. The battery mounting bracket 30 thus projects beyond the edges of the battery 32 to protect the battery 32 from falling liquid particles. The side surfaces 54a, 54b, the longitudinal ends 52a, 52b, and the underside 50 of the battery 32 are exposed outside the chamber defined by the battery mounting bracket 30 to allow cooling and access. The edges 42 can project outwards like an awning or umbrella to protect the battery 32.The edges 42 of the battery mounting bracket 30, which are spaced away from the battery 32, further facilitate cooling and access and provide an additional covering area over the battery 32 to protect the battery 32 from liquid particles.

[0020] The battery 32 is attached to the fluid spray device 12 to protect it from falling liquid particles. The battery 32 is held by support elements 36 such that the stand 22 protects it from unwanted contact. The battery 32 is thus covered by the spray device body 20 and the battery mounting bracket 30 and held by the stand 22 to protect it from falling liquid particles and unwanted contact during operation and transport.

[0021] The spray gun 18 is configured to expel the spray liquid as an atomized mist through the nozzle 60. The trigger 58 is functionally connected to a valve (not shown) inside the spray gun 18 to open and close the flow path through the nozzle 60. The user can grip the pistol handle 56 with one hand and manipulate the orientation of the spray gun 18 to align it. The user can operate the trigger 58 with the hand gripping the pistol handle 56 to control the spraying through the spray gun 18.

[0022] During operation, the battery 32 supplies the motor 26 with electrical energy. The motor 26 generates rotational power and transmits this power to the drive 28. The drive 28 converts the rotational power of the motor 26 into a linear reciprocating motion of the piston 40. The piston 40 moves back and forth on the pump shaft AA and pumps spray liquid from the reservoir 14 through the hose 16 to the spray gun 18. The user pulls the trigger 58 to open the valve in the spray gun 18, and the spray liquid is expelled as an atomized mist through the nozzle 60.

[0023] Fig. 2A is an exploded view of the fluid spray device 12. Fig. 2B is a first isometric view of a fluid spraying device 12. Fig. 2C is a second isometric view of the fluid spray device 12. Fig. 2D is a side view of the fluid spray device 12. Fig. Figure 2E is a front view of the fluid spray device 12 with the door removed to show an interface between piston 40 and drive 28. Fig. 2F is a top view of the fluid spray device 12. Fig. 2A-2F are explained together. The fluid spraying device 12 comprises a spraying device body 20, a stand 22, a pump 24, a battery mounting bracket 30, a battery 32 ( Fig. 2B-2F), a control unit 62, a handle 64, a door 66, a cup 68, a switch 70, a suction valve 72, a pressure regulator 74, a fluid outlet 76, a suction hose 78, a drain hose 80, a supply hose 82, fasteners 104, and spray fasteners 105. The spray device body 20 comprises a bottom 34, a top 84, a first side 86, a second side 88, a front end 90, and a rear end 92. The stand 22 comprises support elements 36 and a base plate 96. Each support element 36 comprises spacer sections 106, interface sections 108, and surface interfaces 110. The base plate 96 comprises a mounting slot 100, a channel opening 114, and spray closure openings 116. The battery mounting bracket 30 comprises edges 42, which define a mounting opening 44 and a lower opening 46, a channel 118 and a projection 120.The battery 32 comprises a top 48, a bottom 50, longitudinal ends 52a, 52b, side surfaces 54a, 54b and a release button 98.

[0024] The stand 22 supports other components of the spraying device 12 on a support surface, for example, the floor. The spraying device body 20 is supported by the stand 22. The stand 22 comprises a pair of support elements 36, each having a pair of legs extending to and connected with the support surface. It is understood, however, that the support elements 36 can have any configuration suitable for supporting the fluid spraying device 12 relative to the surface. The stand 22 can have any number or few support elements 36. For example, the stand 22 can include one, two, three, four, or more support elements 36. In the example shown, the cup 68 is connected to one of the legs and positioned in the opening 102a defined between the legs of the support elements 36.

[0025] The spacer sections 106 of the support elements 36 extend vertically to space the spray device body 20 away from the support surface. In the example shown, the spacer sections 106 form the legs of the support elements 36. Surface transitions 110 are sections of the support elements 36 that adjoin the support surface. For example, the surface transitions 110 can be in contact with a base surface and form a base surface transition of the support elements 36. In the example shown, the surface transitions 110 are formed at the distal ends of each leg formed by the spacer sections 106 of the support elements 36. However, it is understood that the support elements 36 can be configured in any desired way to be in contact with the support surface. For example, the support elements 36 can include rails for connection with the support surface.

[0026] The support elements 36 are connected to the base plate 96 at the interface sections 108. The interface sections 108 are located at the interface between the support elements 36 and other components of the fluid spraying device. In the example shown, the interface sections 108 are directly connected to the base plate 96 to connect the surface interfaces 110 to the base plate 96. However, it is understood that in some examples the interface sections 108 can be directly connected to the spraying device body 20. For example, each support element 36 can be directly connected to the spraying device body 20. The interface sections 108 are located on the side faces 86, 88 of the fluid spraying device 12; however, it is understood that the interface sections 108 can also be located on the longitudinal ends 90, 92 of the spraying device body 20.

[0027] The support elements 36 can have curvatures 112 to increase the distance of the spray device body 20 from the support surface. In the example shown, the support elements 36 are curved between the interface sections 108 and the surface interfaces 110. In some examples, the support elements 36 can be curved between a vertical component of the surface interface 110 and a horizontal bottom interface. The curvatures 112 are arranged at a major horizontal-vertical transition of the support element 36. The battery 32 is framed by at least one substantial curvature 112 of the support elements 36. In the example shown, the curvatures 112 of each support element 36 frame the battery 32. The battery 32 is framed in such a way that the curvature of the support element 36 bends around the battery 32 when the fluid spray device 12 is viewed from the front, left, right and / or rear.For example, a curvature extending vertically downwards from the rear end 52 of the spray device body 20 and a leg extending into . Fig. The 2D bottom connection section extending to the left does not frame battery 32. Conversely, a curve at the same interface frames it, but this curve extends into Fig. The battery 32 has a 2D ground contact section extending to the right. In some examples, each curvature 112 of a support element 36 frames the battery 32.

[0028] The stand 22 supports the battery mounting bracket 30. In the example shown, the base plate 96 is configured to be connected to and support the battery mounting bracket 30. The base plate 96 is connected to the battery mounting bracket 30 to support the battery mounting bracket 30, and thus the battery 32, vertically below the sprayer body 20. The base plate 96 is connected to the sprayer body 20 to support the sprayer body 20 vertically above the mounting surface. The battery mounting bracket 30 is located on a first, lower side of the base plate 96, and the sprayer body 20 is located on a second, upper side of the base plate 96. The base plate 96 is directly connected to the sprayer body 20 and the battery mounting bracket 30.

[0029] The spray device body 20 encloses and / or supports various other components of the fluid spray device 12. The spray device body 20 is positioned above the base plate 96 and can be connected to it. In the example shown, fasteners 105 extend through the base plate 96 and through mounting openings 116 into the spray device body 20 to connect the spray device body 20 to the stand 22. However, it is understood that the spray device 12 can be connected to the stand 22 in any desired manner. The handle 64 extends from the top 84 of the spray device body 20. More precisely, the handle 64 extends from the spray device body 20 and, in some examples, can be formed by a portion of the spray device body 20, with this portion being an integral part of the spray device body 20.In the example shown, the handle 64 is offset laterally (relative to the spray device body 20) in the direction of the first side 86 relative to the pump axis AA (best in . Fig. 2E to be seen). A user can grasp the handle 64 to carry the fluid spray device 12.

[0030] The engine 26 ( Fig. 1A, Fig. 1B and Fig. 3) is arranged within the spray device body 20. The drive 28 is arranged at least partially within the spray device body 20. The pump 24 is connected to the spray device body 20, so that the pump 24 is supported by the spray device body 20. The pump 24 is arranged at least partially in the opening 102b between the legs of the support elements 36. The pump 24 is connected to the spray device body 20 at its front end 90. The pump 24 is connected to the drive 28 via a dynamic interface within a chamber enclosed by the door 66. The door 66 is movable to expose the chamber in which the dynamic interface connection is formed and to facilitate the mounting of the pump 24 on the fluid spray device 12 and the removal of the pump 24 from the fluid spray device 12. The pump body 38 extends vertically downwards relative to the spray device body 20.The suction hose 78 extends from the pump body 38 and is configured to lead into a reservoir, such as the reservoir 14 (. Fig. 1A), extends to connect the pump 24 fluidically to the reservoir 14. The supply hose 82 extends from an outlet (not shown) of the pump 24 to the control unit 62. The drain hose 80 extends from the control unit 62 and is configured to be inserted into the reservoir 14 to drain fluid into the reservoir 14, for example, during priming. The hose 16 ( Fig. 1A) extends from the fluid outlet 76, which is formed in the control unit 62, to a spray gun, for example the spray gun 18 ( Fig. 1A).

[0031] The switch 70 is formed on the first side 86 of the spray device body 20. More precisely, the switch 70 is formed on the spray device body 20. The switch 70 is configured to turn the power of the fluid spray device 12 on and off. The control unit 62 is supported by the spray device body 20. In the example shown, the control unit 62 is attached to the spray device body 20. The control unit 62 extends from a first side 86 of the spray device body 20. The intake valve 72 is supported by the control unit 62. The intake valve 72 is moved into an intake position to draw fluid into the fluid spray device 12 before spraying and is moved into a spray position to direct the spray fluid to the fluid outlet 76 for spraying. A filter (not shown) may be arranged in the control unit 62. The pressure control 74 extends from the control unit 62.The pressure control 74 is used to control the pressure of the liquid supplied downstream to the spray gun 18. In the example shown, the pressure control 74 is a knob that can be turned to increase or decrease the output pressure.

[0032] The battery mounting bracket 30 is supported by a stand 20. The battery mounting bracket 30 extends vertically relative to the underside 34 of the sprayer body 20. The battery 32 is supported by the battery mounting bracket 30 vertically below the sprayer body 20 and parts of the stand 22. The battery mounting bracket 30 is attached to the base plate 96 to protect the electrical components of the fluid sprayer 12. In the example shown, part of the battery mounting bracket 30 extends through the base plate 96 and into the sprayer body 20 to guide the terminals 122 into the sprayer body 20. The terminals 122 establish electrical and / or data communication connections between the battery 32 and other electrical components of the fluid sprayer 12. The terminals 122 exit the battery mounting bracket 30 at a location within the sprayer body 20.The point where the terminals 122 exit the battery mounting bracket 30 is located on a vertical side of the base plate 96 opposite the point where the battery 32 is connected to the battery mounting bracket 30. In the example shown, the channel 118 of the battery mounting bracket 30 extends through the chimney opening 114 into the sprayer body 20. The channel 118 extends vertically from the top of the battery mounting bracket 30 into the sprayer body 20. The chimney opening 114 can completely surround the sides and longitudinal sides of the chimney 118. The chimney opening 114 extends vertically through the base plate 96. In the example shown, the mounting openings 116 also extend vertically through the base plate 96. The chimney 118 forms a closed passage extending vertically from the battery mounting bracket 30 into the sprayer body 20.The channel 118 comprises four side walls on all vertically extending sides of the channel 118, from the battery mounting bracket 30 into the spray device body 20. While the channel has a rectangular cross-section orthogonal to a vertical axis, it is understood that the channel 118 could instead have a square, round, triangular, or other cross-sectional shape orthogonal to a vertical axis. The channel 118 can be formed integrally with the body of the battery mounting bracket 30 or separately.

[0033] The battery mounting bracket 30 is connected to the base plate 96 at the mounting groove 100 on a first side of the base plate 96 and by fasteners 104 that extend through the base plate 96 and into the battery mounting bracket 30 on a second side of the base plate. The slot and fastener arrangement provides tolerance at the mounting interface and facilitates the attachment of the battery mounting bracket 30 to the sprayer body 20. In the example shown, the projection 120 extends from the battery mounting bracket 30 and is configured to engage in the mounting slot 100. In some examples, the width of the projection 120 (later relative to the sprayer body 20 and longitudinally relative to the battery mounting bracket 30) can be adjusted. Fig. (measured 2A-2D) be less than the width of the mounting slot 100 (laterally relative to the spray device body 20 and longitudinally relative to the battery mounting bracket 30 in the Fig. (measured at 2A-2D). The different widths allow the battery mounting bracket 30 to move relative to the base plate 96, with the projection 120 positioned in the mounting slot 100 to align the mounting openings on the battery mounting bracket 30 with the mounting openings through the base plate 96 and to facilitate the fastening of the battery mounting bracket 30 to the base plate 96 with the fasteners 104. While the battery mounting bracket 30 is described as being fastened to the base plate 96 with a portion of the battery mounting bracket 30 projecting into the mounting slot 100 and with fasteners 104, it is understood that the battery mounting bracket 30 can be connected to the spray device body 20 in any desired manner.For example, the battery mounting bracket 30 can be connected exclusively by fasteners, by clamps or by one or more other types of connection.

[0034] In the example shown, the battery mounting bracket 30 is rotated longitudinally relative to the sprayer body 20, since the battery mounting bracket 30 extends longitudinally in the X direction, while the sprayer body 20 extends longitudinally in the Z direction. The battery mounting bracket 30 extends laterally in the Z direction, while the sprayer body 20 extends laterally in the X direction. The longitudinal direction of the battery 32 (along which the battery 32 slides for installation and removal) is arranged transversely to the longitudinal direction of the sprayer body 20. The longitudinal direction of the battery 32 can be orthogonal to the longitudinal center axis of the sprayer body 20. The battery mounting bracket 30 can be mounted such that its longitudinal direction is orthogonal to the longitudinal direction of the sprayer body 30.While the battery mounting bracket 30 is shown rotated longitudinally relative to the sprayer body 20, such that the battery 32 moves laterally relative to the sprayer body 20 but longitudinally relative to the battery mounting bracket 30 during installation and removal, it is understood that in some examples the battery mounting bracket 30 is aligned longitudinally with the sprayer body 20. In such an example, a ZY plane extends through the mounting opening 44 and a rear edge 42 of the battery mounting bracket 30, as well as through the front end 90 and the rear end 92 of the sprayer body 20.

[0035] The battery 32 is supported by a stand 22 and hangs vertically below the underside 34 of the spray device body 20. More precisely, the battery 32 is supported directly by the battery mounting bracket 30, which in turn is supported directly by the base plate 96. In the example shown, the battery 32 is detachably attached to the battery mounting bracket 30, so that the battery 32 can be removed from the fluid spray device 12 for storage, charging, and / or replacement. The battery 32 can be inserted and removed through the mounting opening 44 of the battery mounting bracket 30. In the example shown, the battery 32 is slidably attached to the battery mounting bracket 30. In the example shown, the battery mounting bracket 30 is oriented such that the battery 32 can be inserted and removed through the opening 102c between the support elements 36 of the stand 22.The release button 98 is accessible through the mounting opening 44 and can be actuated to disconnect the battery 32 from the battery mounting bracket 30 and allow the battery 32 to be slid out of the spray device body 20. The battery 32 is inserted into and removed from the battery mounting bracket 30 through the mounting opening 44 of the battery mounting bracket 30. The edge 42 extends outwards relative to the longitudinal end 52a and is positioned vertically above the battery 32, such that the release button 98 is located within the battery receiving chamber 174 defined by the battery mounting bracket 30.

[0036] The battery mounting bracket 30 partially encloses the battery 32. The top 48 of the battery 32 is completely covered by the battery mounting bracket 30 to prevent liquid particles falling around the fluid spray device 12 from falling onto the battery 32. The battery 32 extends through the lower opening 46 of the battery mounting bracket 30, so that the battery mounting bracket partially covers the longitudinal end 52b and the side faces 54a, 54b of the battery 32. The bottom 50 of the battery 32 is not covered by the battery mounting bracket 30. In the example shown, the interface between the stand 22 and the spray device body 20 has a longitudinal length LL1 that is narrower than the width W3 ( Fig. 5A) of battery 32. The longitudinal length LL1 is also narrower than the width W1 ( Fig. 5A) of the battery mounting bracket 30. In the example shown, the interface between the stand and the spray device body 20 has a lateral width W4 that is narrower than the length L2 of the battery 32. The lateral width W4 is also narrower than the length L1 ( Fig. 5B) the battery mounting bracket 30 and the length L3 ( Fig. 5B) of the battery mounting bracket. The spray device body 20 has a lateral width W4, which is greater than either the length L2 ( Fig. 5B) or the width W3 of the battery 32. The spray device body 20 has a longitudinal extent greater than either the length L2 or the width W3 of the battery 32. The spray device body 20 also has a lateral width and a longitudinal extent that are each greater than the width W1 of the battery mounting bracket and the lengths L1, L3 of the battery mounting bracket 30. The entire top of the battery 32 is vertically covered by the battery mounting bracket 30. In various embodiments, the top of the battery 32 is partially or completely vertically covered by both the battery mounting bracket 30 and the spray device body 20.

[0037] The battery 32 is inserted into and removed from the first side 86 of the fluid spray device 12, which is the same side of the fluid spray device 12 where the operating elements of the fluid spray device 12 are located (e.g., switch 70, intake valve 72, pressure regulator 74). This arrangement simplifies user interaction with the fluid spray device 12, as the user can insert, remove, and / or replace the battery while simultaneously having access to the various operating elements of the fluid spray device 12 from the same user position. The battery 32 is described as being accessible through the opening 102c. However, it is understood that the battery 32 can be mounted on the fluid spray device 12 in various orientations to be accessible from other sides of the fluid spray device 12.In some examples, the battery mounting bracket 30 can be arranged about 180 degrees around a vertical axis relative to the orientation shown. In such an orientation, the battery 32 can be accessed through the opening 102d. In such an example, the battery 32 can be accessed from the second side 88 of the spray device 12. In other examples, the battery mounting bracket 30 is oriented such that the battery 32 can be accessed through the opening 102a between the rear legs of the stand 22. In such an example, the battery 32 can be pulled away from the pump 24 during removal and moved toward the pump 24 during installation. In some examples, the battery 32 displaces axially along a radial line extending from the pump axis AA during installation and removal.With such a longitudinal mounting relative to the spray device body 20, the tray 68 can be omitted or positioned elsewhere on the fluid spray device 12 to facilitate access to the battery 32 through the opening 102a. The battery 32 is accessible from the rear end 92 of the spray device 12. The battery 32 can be mounted on and removed from the fluid spray device 12 while the pump 24 remains attached to the fluid spray device 12.

[0038] The battery 32 is arranged vertically below the spray device body 20 to protect it from spray mist. The battery 32 hangs below the spray device body 20, allowing another component of the fluid spray device 12 to be arranged vertically above the battery 32 for protection. The battery mounting bracket 30 is arranged directly vertically above the battery 32. The battery mounting bracket 30 is positioned directly between the spray device body 20 and the battery 32, thus vertically spacing the battery 32 from the spray device body 20. The base plate 96 further vertically spaces the battery 32 relative to the spray device body 20. The battery 32 is arranged vertically below the interface sections 108 of the support elements 36. The edges 42 of the battery mounting bracket 30 form shield sections that project laterally and / or longitudinally relative to the battery 32.The shield sections extend laterally and / or longitudinally to protect the battery 32 from falling spray. The shield sections extend relative to and over the longitudinal ends 52a, 52b and the side surfaces 54a, 54b of the battery 32 to protect the battery 32 from falling liquid splashes, while the longitudinal ends 52a, 52b, the side surfaces 54a, 54b, and the underside of the battery 32 remain at least partially exposed. The edges 42 are spaced from the longitudinal ends 52a, 52b and the side surfaces 54a, 54b to allow airflow between the battery 32 and the battery mounting bracket 30 and to facilitate cooling. The canopies formed by the edges 42 project outwards relative to the battery 32 and are arranged vertically above the battery 32 to protect the battery 32 from falling liquid splashes.

[0039] In some examples, how best to Fig. As can be seen in Figure 2E, the battery 32 is arranged completely beneath the spray device body 20, so that no part of the battery 32 protrudes beyond the circumference of the spray device body 20. The base area of ​​the spray device body 20 is the area within the circumference of the spray device body 20, viewed from above, as shown in Figure 2E. Fig. Figure 2E shows that the battery 32 can be arranged completely within the base area of ​​the spray device body 20 when mounted on the fluid spray device 12. The battery 32 is positioned laterally and / or longitudinally between the surface interfaces 110 of the support elements 36 relative to the spray device body 20, with the surface interfaces 110 configured to contact the support surface. Positioning the battery 32 on the fluid spray device 12, such that the battery 32 is framed by the support elements 36, protects the battery 32 from liquid during spraying and prevents unintentional contact between the battery 32 and other objects (e.g., walls, corners, the user, etc.), for example, when carrying the fluid spray device 12 by the handle 64.

[0040] The fluid spraying device 12 offers significant advantages. The battery 32 supplies the motor 26 with electrical energy to power the pump 24, eliminating the need for an external power source, such as mains electricity. The fluid spraying device 12 can be used in locations where other power sources are inaccessible or impractical to operate. The elimination of power cables also removes the tripping hazard at the work site. The battery mounting bracket 30 connects the battery 32 to the fluid spraying device 12 and positions the battery 32 vertically below it. The battery mounting bracket 30 covers the top of the battery 32 to protect it from liquid particles in the vicinity of the fluid spraying device 12. The battery mounting bracket 30 extends outwards relative to the battery 32 to provide additional protection against falling liquid particles.Since the battery 32 is arranged vertically below the fluid spray device 12, it is additionally protected from liquid that falls around the fluid spray device 12. The battery 32 is arranged between the legs of the support elements 36 (best seen in the figures). Fig. 2C and Fig. 2D), so that the legs prevent accidental contact with the battery 32. The parts of the battery 32 not enclosed by the battery mounting bracket 30 are thus protected from damage by contact. Parts of the battery 32 protrude below the battery mounting bracket 30 and are not covered by it, in order to facilitate user access to the battery 32 and cooling of the battery 32.

[0041] Fig. Figure 3A is a partial cross-sectional view of the fluid spraying device 12 along line 3-3 in Fig. 2C. Fig. Figure 3B is a partial cross-sectional view of the fluid spraying device 12 along line BB in Fig. 3A. Fig. 3A and Fig. 3B are explained together. The spray device body 20, the stand 22, the pump 24, the motor 26, the drive 28, the battery mounting bracket 30, the battery 32, the terminal 61, the handle 64, the switch 70, and the supply hose 82 of the fluid spray device 12 are shown. The spray device body 20 comprises a bottom 34, a top 84, a first side 86, a second side 88, a front end 90, a rear end 92, and a body cavity 94. The stand 22 comprises support elements 36 and a base plate 96. The mounting slot 100 and the channel opening 114 of the base plate 96 are shown. The pump 24 comprises a pump body 38, a piston 40, check valves 124a, 124b, a pump inlet 126 and a pump outlet 128. The piston 40 comprises a head 130, a neck 132 and a piston body 134. The motor 26 comprises a motor body 136 and an output shaft 138.The drive 28 comprises a gearbox 140, an eccentric 142, an arm 144, and a drive element 146. The bracket 31, the edges 42, the mounting opening 44, the lower opening 46, and the channel 118 of the battery mounting bracket 30 are shown. The channel 118 includes chimney sides 169, a wire opening 170, and a channel 171. The top 48, bottom 50, longitudinal ends 52a, 52b, and side parts 54a, 54b of the battery 32 are shown.

[0042] The stand 22 supports other components of the fluid spraying device 12. The spraying device body 20 is directly connected to the stand 22. The drive components of the fluid spraying device 12 are supported by the spraying device body 20, which defines the spraying device body 20. The motor 26, the drive 28, and the pump 24 are each supported by the spraying device body 20. The motor 26 is located inside the spraying device body 20. The motor housing 136 is attached to the spraying device body 20. The motor shaft 138 is configured to rotate about the motor axis MM and provides the rotational power of the motor 26. The motor 26 is located vertically above the battery 32 and the battery mounting bracket 30. The motor 26 can be positioned directly above the battery 32 and / or the battery mounting bracket 30, so that a vertical line passes through the battery 32 and / or the battery mounting bracket 30 and the motor 26.In some examples, a vertical line can extend through the battery 32, the battery mounting bracket 30, the base plate 96, and the motor 26. Such a vertical line can be arranged parallel to the pump axis AA.

[0043] The drive 28 is connected to the motor 26 to receive the rotational power of the motor 26. The gearbox 140 is connected to a pinion of the motor shaft 138 to receive the rotational power of the motor 26. The eccentric 142 is rotated by the gearbox 140 and, via the drive arm 144, drives the reciprocating motion of the drive element 146. Thus, it can be assumed that the drive 28 in the example shown includes a crank.

[0044] The pump 24 is attached to the sprayer body 20. The pump 24 is connected to the fluid sprayer 12 by a static interface that secures the pump body 38 to the sprayer body 20, and a dynamic interface between the actuator 28 and the piston 40 to cause the piston 40 to move back and forth. In the example shown, the clamp 61 forms the static connection with the sprayer body 20. The clamp 61 is located on the outside of the pump body 38 and is configured to engage with the sprayer body 20 to secure the pump 24 to the fluid sprayer 12. Part of the sprayer body 20 is received in a gap between the rings 148a and 148b that form the clamp 61.One or both of the rings 148a, 148b can be movable relative to the pump body 38 to change the size of the gap and actuate the clamp 61 between an engaged and a disengaged state. For example, ring 148a can be movable along the pump axis AA relative to the pump body 38, and ring 148b can be statically connected to the pump body 38. In some examples, one or both of the rings 148a, 148b can be connected to the pump body 38 via a threaded connection.

[0045] The piston 40 is located at least partially within the pump body 38. The piston 40 is connected to the drive element 146 so that it can be moved back and forth by the drive 28. The piston body 134 extends from the interior of the pump body 38 and through a first pump seal out of the pump body 38. A second pump seal forms a sealed interface between the piston 40 and the pump body 38. The second pump seal can be attached to the piston 40 to move with it, or it can be located at a fixed position within the pump body 38 so that the piston 40 moves back and forth relative to the second pump seal. Due to the relative movement at the seal interface, the first and second pump seals can be considered dynamic seals.The piston 40 is connected to the drive element 146 via a head and slot connection, although other connection types are also possible, such as a pin connection. The head 130 is received in a slot of the drive element 146, and the neck 132 connects the head 130 to the piston body 134. The head 130 has a larger diameter than the neck 132. The piston body 134 can have a larger diameter than the neck 132. The head 130 can be inserted into the slot through an opening radially oriented to the pump axis AA. The neck 132 extends through a lower opening of the slot, which is axially oriented to the pump axis AA.

[0046] The check valve 124a is an inlet check valve that, with the exception of the moving valve element, generally remains stationary relative to the pump body 38 during operation. The check valve 124a is located near the pump inlet 126. One valve element of the check valve 124a moves to open and close the flow path through the check valve 124a, but other components of the check valve 124a do not move relative to the pump body 38. The check valve 124b is functionally connected to the piston 40 and moves back and forth with the piston 40 along axis AA. The check valve 124b is located inside the piston 40. The check valves 124a and 124b are each one-way valves that allow flow from upstream to downstream and prevent flow from downstream to upstream. The check valves 124a and 124b can be, among other things, ball valves.

[0047] The pump 24 can be moved longitudinally MD1 from the front end 90 to the rear end 92 to attach the pump 24 to the fluid spray device 12. Part of the spray device body 20 is received into the slot of the clamp 61, and the piston head 130 is received into the slot of the drive element 146. The ring 148a of the clamp 61 is tightened to bring the clamp 61 into the locked position, thereby securing the pump 24 to the housing 96. The pump 24 can be removed from the spray device body 20 by loosening the ring 148a of the clamp 61 and then pulling the pump 24 away from the spray device body 20 in the direction MD2. In the example shown, directions MD1 and MD2 are transverse to the installation direction D1 and the removal direction D2 of the battery 32 relative to the battery mounting bracket 30, as shown in Fig. 5C is shown. However, it is understood that in some examples the direction MD1 may coincide with the distance direction D2 of battery 32 and the direction MD2 may coincide with the installation direction D1 of battery 32.

[0048] The spray device body 20 is attached to the base plate 96 and supported by the stand 22. The spray device body 20 encloses various components of the fluid spray device 12. Specifically, the spray device body 20 encloses electrical components of the fluid spray device 12, such as a controller and a motor 26, within the body cavity 94. The battery mounting bracket 30 is attached to the base plate 96. The base plate 96 is positioned vertically between the spray device body 20 and the battery mounting bracket 30. The battery mounting bracket 30 is located on the underside of the base plate 96. The battery 32 is attached to and held by the battery mounting bracket 30. As shown, the edges 42 of the battery mounting bracket form projections that extend above the top 48 of the battery 32 and project outwards and downwards to partially cover the side surfaces 54a, 54b of the battery 32.The battery 32 is suspended from the battery mounting bracket 30. The battery mounting bracket 30 holds the battery 32 away from the stand 22 and the spray device body 20. The battery 32 is suspended from the battery mounting bracket 30 in such a way that the underside 50 of the battery 32 is not directly supported by any structure that is in contact with the underside 50. The underside 50 is thus suspended. In some embodiments, the underside 50 of the battery 32 does not touch anything; the underside 50 does not touch any other components of the fluid spray device 12 and is suspended above the support surface or the base.

[0049] The channel 118 forms part of the battery mounting bracket 30, extending through the base plate 96 and into the spray device body 20. The channel 118 is sealed to the outside of the body 31 of the battery mounting bracket 30, preventing liquid from entering the channel 118 or the interior of the battery mounting bracket 30 from the outside. For example, the channel 118 can be integral with other parts of the battery mounting bracket 30 to prevent liquid from penetrating between these parts and into the interior of the battery mounting bracket 30, for instance, by forming the body 31 of the battery mounting bracket 30 and the channel 118 from a single, cohesive material.

[0050] Channel 118 extends vertically relative to the body 31 of the battery mounting bracket 30 and into the spray device body 20. Channel 118 extends vertically such that it forms the uppermost part of the battery mounting bracket 30. The body of channel 118 is formed by the chimney sides 169. The chimney sides 169 extend vertically from the top of the battery mounting bracket 30, so that channel 118 is a vertical projection of the battery mounting bracket 30. As explained above, the chimney sides 169 can be formed integrally with the body 31 of the battery mounting bracket 30. Channel 118 extends through the chimney opening 114 formed in the base plate 96. Channel 118 projects vertically through the base plate 96 and into the body cavity 94 defined by the spray device body 20.The interface between the channel 118 and the body 31 of the battery mounting bracket 30 can be vertically extended from the base plate 96 of the sprayer, so that a gap is formed between them. In the example shown, the channel 118 projects vertically beyond the bottom 34 of the sprayer body 20, so that the wire opening 170 is located within the cavity 94 of the sprayer body 20.

[0051] Channel 118 carries the terminals 122 to establish electrical and / or data communication connections between the battery 32 and other electrical components of the fluid spraying device 12. The terminals 122 exit channel 118 at a location within the cavity 94 of the spraying device body 20. The point where the terminals 122 exit the battery mounting bracket 30 can be located directly vertically below the components of the motor 26, thus minimizing the length of the wires from the battery 32.

[0052] The channel passage 171 is formed within the channel 118. The channel passage 171 is a vertically oriented passage defined by the vertical walls that form the chimney sides 169. The channel passage 171 has a cable opening 170 at a vertical upper end, which provides a location for the terminals 122 to exit from the battery mounting bracket 30 into the spray device body 20. The channel 171 is oriented along a vertical axis. The channel 171 is elongated along an axis. The axis of the channel 171 can be orthogonal to the motor axis MM. The axis through the channel 171 can be parallel to the pump axis AA. The wire opening 170 is formed by the portion of the channel 118 that is furthest from the body 31 of the battery mounting bracket 30. The wire opening 170 is formed at the uppermost part of the battery mounting bracket 30.Since the wire opening 170 is formed at the uppermost part of the battery mounting bracket 30, it is located within the spray device body 20 to ensure that the terminals 122 are not exposed at any points outside the spray device body 20. The terminals 122 are thus located along their entire length in at least one of the two parts, the battery mounting bracket 30 and the spray device body 20. The channel 171 has an opening 173 at its vertical lower end, near the interface between the channel 118 and the housing 31, which forms a second wire opening 173. The second wire opening 173 provides a location through which the connectors 122 can enter the channel 171 from inside the housing 31 of the battery mounting bracket 30.

[0053] Channel 171 can be a straight channel without bends between the upper wire opening 170 and the lower wire opening 173 on the body 31. The straight channel 171 facilitates the routing of the connectors 122 and allows the use of shorter connectors 122. Channel 171 is enclosed between the two end openings 170 and 173. In some embodiments, the walls 169 between the base and the tip of channel 118 are continuous, so that channel 171 has no laterally or longitudinally oriented openings. By forming channel 118 with continuous walls and only the upper and lower openings 170 and 173, fluid migration is prevented and the electronic components are protected from this fluid.

[0054] The side walls 169 of the channel extend vertically from the body 31 of the battery mounting bracket 30 through the base plate 96 and through the underside 34 of the sprayer body 20. The channel 118, extending through the base plate 96 and the underside 34, positions the wire opening 170 within the sprayer body 20 and vertically above the underside 34. Thus, the wire opening 170 is located vertically above the base of the sprayer body 20, which is formed by the underside 34. By positioning the wire opening 170 vertically above this base and within the cavity 94 of the sprayer body 20, the electrical components of the battery 32 are protected from liquid. The wire opening 170 is positioned such that any liquid that may accumulate inside the sprayer body on the underside 34 is located vertically below the wire opening 170.In this way, gravity pulls the liquid away from the wire opening 170. The wire opening 170 is positioned so that no liquid can penetrate the battery mounting bracket 30. The sealed interface between the channel 118 and the body of the battery mounting bracket 30 also prevents liquid ingress and protects the electrical components.

[0055] The wire opening 170 is arranged within the cavity 94 of the spray device body 20 such that the spray device body 20 protects the electrical connections by shielding the wire opening 170 from falling spray fluid. The wire opening 170 is arranged vertically between the top 84 and the bottom 34. The wire opening 170 is arranged directly between the top 84 and the bottom 34. The wire opening 170 is arranged between the first side 86 and the second side 88. The wire opening 170 is arranged directly between the first side 86 and the second side 88. The wire opening 170 is arranged between the front end 90 and the rear end 92. The wire opening 170 can be arranged directly between the front end 90 and the rear end 92. The wire opening 170 can be positioned directly between the walls of the spray device body 20, which form the front end 90 and the rear end 92.By positioning the wire opening 170 inside the cavity 94 of the spray device body 20, the wire opening 170 is protected from falling spray mist.

[0056] During operation, the battery 32 supplies the motor 26 with electrical energy to drive it. The motor 26 generates a rotary motion via the motor shaft 138 and drives the actuator 28. The actuator 28 converts the rotary motion into a reciprocating motion along the axis AA. The motor axis MM is oriented perpendicular to the orientation of the pump axis AA, and in some examples, these orientations may be orthogonal. In some examples, the motor axis MM intersects the pump axis AA directly.

[0057] The piston 40 moves vertically back and forth along the pump axis AA during each upward or suction stroke and downward or pumping stroke. In the example shown, the pump 24 is a double positive displacement pump that discharges fluid during each upward and downward stroke. During the upward stroke, the check valve 124b closes and the check valve 124a opens. The spray fluid is drawn into the upstream chamber between the check valve 124a and the check valve 124b and discharged from a downstream chamber downstream of the check valve 124b through the pump outlet 128. The downstream chamber is formed between the piston body 134 and the pump body 38. After completion of the upward stroke, the actuator 28 switches, and the piston 40 is driven by the downward stroke. During the downward stroke, the check valve 124a closes and the check valve 124b opens.The spray fluid is forced from the upstream chamber through the check valve 124b into the downstream chamber and from the downstream chamber through the pump outlet 128 downstream.

[0058] The fluid spray device 12 offers significant advantages. The battery 32 is at least partially oriented vertically to the motor 26, enabling a compact arrangement that allows for use in various locations and a wide range of spraying environments. The battery mounting bracket 30 extends from outside the spray device body 20 through the base plate 96 and vertically through the bottom 34 of the spray device body 20 into the cavity 94 defined by the spray device body 20. More precisely, the channel 118 extends into the body cavity 94 of the spray device body 20, such that the wire opening 170 is positioned vertically above the floor of the body cavity 94, which is formed by the bottom 34.The vertical positioning of the wire opening 170 above the base formed by the underside 34 protects electrical components from liquid that could penetrate the sprayer body 20 and accumulate on the base. The arrangement of the wire opening 170 within the body cavity 94 of the sprayer body 20 also prevents falling liquid from reaching the wire opening 170, as the liquid strikes the sprayer body 20 before it can fall to the wire opening 170. The channel 118 is sealed to the body 31 of the battery mounting bracket 30 (e.g., by integral design) to prevent liquid from entering the interior of the channel 118 or the battery mounting bracket 30. The terminals 122 can be relatively short because the battery 32 is located in close proximity to the motor 26.The elimination of excess wires reduces material consumption and the length of flexible components, resulting in a robust spray device. The short distance between the point where the terminals 122 exit the battery mounting bracket 30 and the battery facilitates the compact configuration of the fluid spray device 12. The battery 32 is positioned vertically below the spray device body 20 and the battery mounting bracket 30 to protect it from falling liquid spray mist. The fluid spray device 12 can be used in various environments where no power supply is available. The battery 32 can be easily removed and replaced with another battery 32 to continue spraying even if one battery 32 loses its power.

[0059] Fig. Figure 4 is a front view of the fluid spray device 12, showing the fluid spray device 12 in a suspended orientation. The fluid spray device 12 is shown in the orientation it is in when carried by a user by the handle 64. The BB axis is a vertical axis passing through the center of gravity of the fluid spray device 12. The BB axis is inclined relative to the AA axis, which is vertically oriented when the fluid spray device 12 is supported on the surface by the stand 22. The BB axis passes through the battery mounting bracket 30. In some examples, the BB axis may pass through the battery 32. A plane on the BB axis extending longitudinally relative to the fluid spray device 12 (i.e., perpendicular to the one shown in Figure 4) is the BB axis. Fig. (as shown in Figure 3), passes through the battery mounting bracket 30 and can pass through the battery 32. The AA axis runs transversely to such a plane. During transport of the fluid spray device 12, the battery 32 is positioned vertically below the spray device body 20, thus preventing unwanted contact with the battery 32.

[0060] The handle 64 is offset laterally from a plane on the axis AA and extends longitudinally relative to the fluid spray device 12 (i.e., perpendicular to the axis AA). Fig. (3 shown in view). The battery 32 and the battery mounting bracket 30 lower the center of gravity, so that the fluid spray device 12 is positioned in the Fig. The position shown in Figure 4 swings while the fluid spray device 12 is carried on the handle 64. The lower center of gravity moves parts of the stand 22 out of the user's path. The lower center of gravity positions parts of the battery mounting bracket 30 and the spray device body 20 between the user and the battery 32. With axis BB defining a vertical axis, the battery mounting bracket 30 is positioned such that a horizontal plane extends through both the battery mounting bracket 30 and parts of the battery 32 located outside the chamber defined by the battery mounting bracket 30. The lower center of gravity facilitates transport and protects the battery 32 from unwanted contact.

[0061] Fig. 5A is a front view of the battery mounting bracket 30 and the battery 32. Fig. 5B is a first side view of the battery mounting bracket 30 and the battery 32. Fig. 5C is a second side view of the battery mounting bracket 30 and the battery 32. Fig. 5D is a first isometric view of the battery mounting bracket 30. Fig. 5E is a second isometric view of the battery mounting bracket 30. Fig. Items 5A-5E are explained together. The battery mounting bracket 30 comprises a bracket body 31, an upper edge 42 defining a mounting opening 44 and a lower opening 46, a channel 118, a projection 120, a first lateral section 150, a second lateral section 152, a lip 154, a mounting block 156, mounting openings 158, upper projections 160, and lower projections 162. The edges 42 define a first wing 164, a second wing 166, and a rear 168. The channel 118 comprises channel sides 169, a wire opening 170, lateral sections 176a and 176b, a chimney cap 178, and flanges 180a-180d. The battery 32 comprises a top 48, a bottom 50, longitudinal ends 52a, 52b, side sides 54a, 54b and a button 98.

[0062] The battery mounting bracket 30 is configured to be attached to the fluid spray device 12 ( Fig. 1A-4). The battery mounting bracket 30 is formed by connecting the first lateral section 150 to the second lateral section 152, for example, by fasteners. A liquid-tight seal can be formed at the interface between the first lateral section 150 and the second lateral section 152. The body 31 of the battery mounting bracket 30 is formed by the first lateral section 150 and the second lateral section 152. However, it is understood that the battery mounting bracket 30 can be designed in any desired manner. In some examples, the battery mounting bracket 30 is designed as a single-piece component, for example, by molding, casting, etc. The first lateral section 150 and the second lateral section 152 define a chamber 174 in which the battery 32 is mounted. The mounting block 156 projects vertically upwards from the chamber 174.Channel 118 extends vertically upwards from mounting block 156 and is on a longitudinal centerline C (. Fig. 5D) of the battery mounting bracket 30 arranged.

[0063] Channel 118 is a vertical projection that defines a path for wires extending from the contacts with the battery 32 and out of the battery mounting bracket 30. Channel 118 is sealed to the body 31 of the battery mounting bracket 30 such that no fluid can escape between channel 118 and the body 31 of the battery mounting bracket 30 and into the interior of the battery mounting bracket 30. In the example shown, channel 118 is formed integrally with the battery mounting bracket 30. Similar to the battery mounting bracket 30, channel 118 includes two lateral sections 176a, 176b that fit together to form channel 118. Lateral section 176a can be formed as an integral projection from the first lateral section 150 that forms the body 31 of the battery mounting bracket 30.The lateral section 176b can be formed as an integral projection from the second lateral section 150, which forms the body 31 of the battery mounting bracket 30. The channel 118 can be symmetrical about the centerline CL of the battery mounting bracket 30. In the example shown, the lateral section 176a is a mirror image of the lateral section 176b; however, it is understood that not all examples of the channel 118 are mirror images of the centerline C of the battery mounting bracket 30. The lateral side 176a fits with the lateral side 176b at a sealed interface to prevent fluid from passing through the body of the channel 118 into the channel 171. Fig. 3B).

[0064] The chimney sides 169 extend vertically from the top of the battery mounting bracket 30 and define the channel 171 through the channel 118. In the example shown, the channel sides 169 define a body having a rectangular cross-section orthogonal to a vertical axis. However, it is understood that the channel sides 169 can be arranged to have any desired cross-sectional shape relative to the vertical axis.

[0065] The flanges 180a-180d extend laterally relative to the sides of the channel 169. In the example shown, flanges 180a and 180c are formed on the side 176a, and flanges 180b and 180d are formed on the side 176b. Flanges 180a and 180b form a first wing at a front end of the channel 118, and flanges 180c and 180d form a second wing at a rear end of the channel 118. Each flange 180a-180d extends from a base of flange 180a-180d on the body 31 to a tip of flange 180a-180d near the channel cover 178, towards the centerline CL. Thus, each wing has a tapered lateral width between a base on the mounting body 31 and an opposite end of the wing, which is vertically spaced from the mounting body 31. The chimney cover 176 projects beyond the upper edges of the flanges 180a-180d and forms the top of the duct 118.

[0066] The flanges 180a-180d facilitate the installation of the battery mounting bracket 30. The flanges 180a-180d converge so that the battery mounting bracket 30 can be pivoted into the mounting position, with the projection 120 in the mounting slot 100 (best in Fig. (2A to be seen) is arranged on the base plate 96. The flanges 180a-180d can engage with the edges of the battery plate 96 that define the channel 114 to prevent unwanted rotation of the battery mounting bracket 30 about a vertical axis. The flanges 180a-180d also provide additional structural support to the channel 118 to create a robust assembly and prevent unintentional contact damage to the channel 118.

[0067] The chimney cover 178 is formed at the upper end of the channel 118, opposite the end of the channel 118 that is connected to the body 31 of the battery mounting bracket 30. The chimney cover 178 is a rounded tip formed by a convergence of the chimney sides 169. The chimney cap 178 projects beyond the upper ends of the flanges 180-180d. The wire opening 170 is a slot formed by the chimney cap 178 through which the connectors 122 extend to electrically connect the battery 32 to other components of the fluid spraying device 12, such as the motor 26. Fig. 1A, Fig. 1B and Fig. 3A). The wire opening 170 is dimensioned such that it is firmly connected to the terminals 122 at the point where the terminals 122 exit the channel 118. The wire opening 170 is laterally extended relative to the orientation of the battery mounting bracket 30. The wire opening 170 is the only opening through the channel 118 that is exposed on the outside of the battery mounting bracket 30. In some embodiments, a seal, for example a sealing sleeve, may be arranged within the wire opening 170 between the terminals 122 and the edges of the chimney cap 176 that delimits the opening 170. The seal prevents liquid from entering the battery mounting bracket 30 between the terminals 122 and the channel 118, and can prevent contact between the terminals 122 and the edges of the wire opening 170 formed by the channel 118, thus protecting the terminals 122 from unwanted contact damage.However, it goes without saying that not all examples are so limited.

[0068] The chimney cover 178 is the uppermost part of the battery mounting bracket 30 and the part of the battery mounting bracket 30 furthest from the battery 30. The wire opening 170 is formed by the part of the channel 118 furthest from the body 31 of the battery mounting bracket 30. The wire opening 170 is the uppermost part of the battery mounting bracket 30. The channel 118 extends into the spray device body 20 (best seen in the Fig. 3A and Fig. 3B), such that the channel 118 is located within the spray device body 20 and above the base formed by the underside 34 of the spray device body 20. The wire opening 170, formed by the part of the channel 118 furthest from the body 31 and being the only external opening through the channel 118, protects the battery 32 and the electrical connections 122 from liquid during operation. Due to gravity, the liquid falls along the sides 169 of the channel 118 and away from the wire opening 170. The wire opening 170 can be considered to be aligned on an XZ plane.

[0069] The projection 120 extends from the mounting block 156 and projects laterally beyond an edge of the mounting block 156. In the example shown, the projection 120 is formed as part of the second lateral section 152. The projection 120 is configured to engage with the slot 100 to secure the battery mounting bracket 30 to the fluid spray device 12. Mounting openings 158 are formed in the mounting block 156. The mounting openings 158 are formed on a lateral side of the mounting block 156 opposite the projection 120. The mounting openings 158 are formed in the first lateral section 150. The mounting openings 158 are configured to accommodate fasteners 104 (best in Fig. 2A to be seen) to attach the battery mounting bracket 30 to the fluid spray device 12.

[0070] The first wing 164 extends vertically downwards relative to the mounting block 156. The first wing 164 has a contour 172a. The second wing 166 extends vertically downwards relative to the mounting block 156. The second wing 166 has a contour 172b. The contours 172a and 172b widen the chamber 174 laterally, so that the mounting opening 44 is wider near its lower end than near its upper end. The width W1 of the mounting opening 44 near the lower opening 46 is greater than the width W2 of the mounting opening 44 above the contours 172a and 172b. The first wing 164 and the second wing 166 project outwards in the form of an awning or umbrella to protect the battery 32 from sprayed liquid.

[0071] Upper projections 160 are formed on the first wing 164 and the second wing 166. The upper projections 160 extend into the chamber 174. The upper projections 160 are designed as rails that stiffen the battery mounting bracket 30 and assist in guiding a battery into the battery mounting bracket 30 during assembly. Lower projections 162 are formed on the first wing 164 and the second wing 166. More precisely, the lower projections 162 are formed on the sections of the first wing 164 and the second wing 166 that are located below the contours 172a, 172b. The lower projections 162 are designed as rails that stiffen the battery mounting bracket 30 and can serve as guides when installing a battery into the battery mounting bracket 30.In the example shown, the lower projections 162 extend further into the chamber 174 and to the rear 168 of the battery mounting bracket 30 than the upper projections 160. The battery mounting bracket 30 is configured to accommodate batteries of different sizes. The upper projections 160 support the mounting of relatively smaller batteries, while the lower projections 162 support the mounting of relatively larger batteries. The widening between the first wing 164 and the second wing 166 facilitates the mounting of different battery sizes, while maintaining the clearances between the battery mounting bracket 30 and the battery 32.

[0072] The battery 32 is inserted into and removed from the chamber 174 through the mounting opening 44. The mounting opening 44 is a lateral opening of the battery mounting bracket 30 and not a top or bottom opening. The chamber 174 further includes a bottom opening 46 through which a portion of the battery 32 extends when the battery 32 is attached to the battery mounting bracket 30. The lip 154 ​​defines the mounting opening 44 and is formed, at least in part, by the first wing 164 and the second wing 166. As is best described in the Fig. 5B and Fig.As can be seen in Figure 5C, the lip 154 ​​extends further forward on its vertical upper surface than at its distal ends, which are located where the mounting opening 44 transitions into the lower opening 46. As shown, the battery mounting bracket 30 has a length L3 near the transition between the mounting opening 44 and the lower opening 46, and a length L1 near the upper surface of the lip 154. Lengths L1 and L3 are greater than the length L2 of the battery 32. Length L1 is greater than length L3, so the portion of the battery mounting bracket 30 that defines the mounting opening 44 extends outward relative to the battery 32 to cover it, similar to an umbrella or awning.The lip 154 ​​is inclined forward to extend further longitudinally relative to the battery 32 and to additionally cover the battery 32 to prevent liquid from falling onto the battery 32 or the button 98.

[0073] The battery 32 is slidably mounted on the battery mounting bracket 30. The battery 32 is configured to slide towards D1 to attach to the battery mounting bracket 30 and to slide towards D2 to detach from the battery mounting bracket 30. By linear sliding, the battery 32 attaches to or detaches from the battery mounting bracket 30. When the battery 32 is attached to the battery mounting bracket 30, the top 48 is completely within the chamber 174 and is overlapped by the battery mounting bracket 30.

[0074] When the battery 32 is attached to the battery mounting bracket 30, the battery 32 is located partially inside and partially outside the chamber 174. The battery 32 protrudes from the chamber 174 through the lower opening 46. The battery 32 hangs from the battery mounting bracket 30 through the lower opening 46. Each of the longitudinal ends 52a, 52b and each of the side faces 54a, 54b are partially located inside the chamber 174 and protrude from the chamber 174 through the lower opening 46. In the example shown, the battery base 50 is not located inside the chamber 174. The base 50 is located entirely outside the chamber 174, so that the base 50 is not overlapped or obscured by any part of the battery mounting bracket 30. The parts of the battery mounting bracket 30 that define the lower opening 46 (e.g. the edges 42) are arranged vertically between the top 48 and the bottom 50 of the battery 32.

[0075] The side surface 54a is spaced from an opposite edge 42. The side surface 54a does not touch the first lateral section 150. An air gap is formed between the side surface 54a and the first wing 164. The side surface 54a does not touch either the upper projection 160 or the lower projection 162 when the battery 32 is secured in the battery mounting bracket 30. The side surface 54b is spaced from an opposite edge 42. The side surface 54b does not touch the second lateral section 152. An air gap is formed between the side surface 54b and the second wing 166. The side surface 54b does not touch either the upper projection 160 or the lower projection 162 when the battery 32 is mounted in the battery mounting bracket 30. The width W3 of the battery 32 is smaller than the width W1 and larger than the width W2. However, none of the side surfaces 54a, 54b touch any part of the battery mounting bracket 30.In some examples, the longitudinal end 52b is spaced away from the battery mounting bracket 30, creating an air gap between the longitudinal end 52b and the battery mounting bracket 30. This allows the battery 32 to be attached to the battery mounting bracket 30 such that only the top 48 contacts the battery mounting bracket 30, while the longitudinal ends 52a, 52b, the side faces 54a, 54b, and the bottom 50 do not contact the battery mounting bracket 30. The air gaps formed between the battery 32 and the battery mounting bracket 30 facilitate airflow into the chamber 174 between the battery 32 and the battery mounting bracket 30, thus improving the cooling of the battery 32.

[0076] The mounting arrangement between the battery mounting bracket 30 and the battery 32 offers significant advantages. The edges of the battery mounting bracket 30 extend beyond the sides of the battery 32 to protect the battery 32 from falling liquid particles. Air gaps are formed between the battery 32 and the battery mounting bracket 30 to facilitate cooling of the battery 32. The battery 32 protrudes through the lower opening 46 of the battery mounting bracket 30 to expose parts of the battery 32 and further facilitate cooling. The battery mounting bracket 30, which is wider relative to the battery 32, protects the exposed parts of the battery 32 that protrude below the lower opening 46 from falling liquid particles. The channel 118 offers significant advantages. The channel 118 and the battery mounting bracket 30 have a sealed interface (e.g.,The channel 118 is adjacent to the mounting body 31, preventing liquid from entering the interior of the battery mounting bracket 30 between the channel 118 and the mounting body 31. The channel 118 projects vertically from the battery mounting bracket 30, away from the chamber in which the battery 32 is located. The channel 118 extends into the spray device body 20, so that the wire opening 170 is located within the spray device body 20 and is protected from liquid particles by the spray device body 20. The flanges 180a-180d ensure a structurally robust channel 118, which further protects the terminals 122. Thus, the channel 118 protects the terminals 122 from both mechanical and liquid damage.
