  • the tip assembly includes a tip housing that is coupleable to the housing of the paint sprayer and that is configured to be in fluid communication with the outlet valve along a spray axis, and a tip positioned within the tip housing and movable within the housing between a retracted position and an operative position.
  • the tip is in communication with the actuator such that engagement of the actuator moves the tip from the retracted position to the operative position and disengagement of the actuator moves the tip from the operative position to the retracted position.
  • the tip assembly may further include a magnet.
  • the tip may be magnetically coupled to the magnet in the retracted position and decoupled from the magnet in the operative position.
  • the magnet may be a permanent magnet and the tip assembly may further include a solenoid and a biasing mechanism.
  • the solenoid and the biasing mechanism may be positioned within the tip housing.
  • the solenoid may be positioned adjacent the permanent magnet.
  • engagement of the actuator may be configured to actuate the power source and direct current in a first direction through the solenoid thereby creating a magnetic field that opposes a magnetic field of the permanent magnet and decoupling the tip from the permanent magnet such that the biasing member biases the tip from the retracted position to the operative position.
  • disengagement of the actuator may be configured to disengage the power source such that current runs in a second direction through the solenoid thereby creating a magnetic field that attracts the magnetic field of the permanent magnet, overcomes the bias of the biasing mechanism, and moves the tip from the operative position to the retracted position.
  • the magnet may be an electro-permanent magnet and the tip assembly further includes a solenoid and a biasing mechanism.
  • the solenoid and the biasing mechanism are positioned within the tip housing.
  • the solenoid is positioned around the electro-permanent magnet.
  • a magnetic field of the electro-permanent magnet may attract the tip to retain the tip in the retracted position.

  • the second chamber may be in communication with the outlet valve.
  • the paint sprayer may further include a biasing mechanism that biases the tip into the retracted position in which the tip prevents communication between the first chamber and the second chamber.
  • Actuation of the actuator may allow paint to flow into the second chamber thereby increasing a pressure of the paint on the tip to move the tip against the bias of the biasing mechanism and into the operative position.
  • Disengagement of the actuator may stop paint flow thereby decreasing the pressure of the paint on the tip such that the biasing mechanism moves the tip to the retracted position.
  • the tip may define a longitudinal axis, the tip may be movable along the longitudinal axis between the retracted position and the operative position and the tip may be rotatable about the longitudinal axis.

  • the paint sprayer 10 includes a housing 18 that has an actuator 26 and a removably attachable paint container 30 for holding paint to be sprayed.
  • a pump 34 e.g., a gear pump or any suitable pump.
  • An outlet valve 38 is fluidly coupled to and extends from the pump 34 through the housing 18.
  • the paint sprayer 10 further includes a motor 42 and a transmission 48 (e.g., a multi-stage planetary transmission) to drive the pump 34 to displace the paint from the paint container 30 and move paint from the container 30 to the outlet valve 38.
  • a power source is operatively coupled to the motor 42.
  • the power source is a battery pack 52 that is removably coupled to the paint sprayer 10 and configured to actuate the motor 42.
  • the paint sprayer 10 includes a printed circuit board (“PCB”) 56 that has a controller 60, which communicates with the battery pack 52 and the actuator 26.
  • PCB printed circuit board
  • FIGS. 2-5 illustrate the tip assembly 14 according to one embodiment of the invention.
  • the tip assembly 14 includes a housing 100 that defines a longitudinal axis A ( FIG. 3 ) and tip 102 that is movable within the housing 100.
  • the housing 100 includes an opening 104, a first channel 108, a second channel 112, and a third channel 116.
  • the opening 104 defines a spray axis B and is aligned with the outlet valve 38.
  • the first and second channels 108, 112 are arranged generally parallel to the longitudinal axis A.
  • the third channel 116 is arcuate and couples the first and the second channels 108, 112 to one another.
  • a permanent magnet 120 and a solenoid 124 i.e., wrapped motor coil
  • the solenoid 124 is configured to communicate with the battery pack 52 and the controller 60.
  • a biasing mechanism 128 i.e., spring
  • a biasing mechanism 128 is positioned within the housing 100 adjacent to the permanent magnet 120.
  • the tip 102 includes a body 140 that has an opening 144 extending therethrough and a projection 148 extending therefrom.
  • the tip 102 is received within the body 140 along the longitudinal axis A.
  • the spring 128 is positioned between the permanent magnet 120 and the tip 102.
  • the projection 148 of the tip 102 is received in and slideable within either the first channel 108 or the second channel 112.
  • the tip 102 is movable (i.e., translatable or slideable) within the housing 100 to move the opening 144 into and out of alignment with the opening 104 in the housing 100. That is, the tip 102 is movable within the housing 100 between a first, operative position ( FIG. 4 ) and a second, retracted position ( FIG. 5 ). In the operative position, the opening 144 of the tip 102 is aligned with the opening 104 in the housing 100, and in the retracted position, the opening 144 of the tip 102 is out of alignment with (i.e., spaced apart from) the opening 104 in the housing 100. Also, in the retracted position, the opening 144 in the tip 102 is positioned within the housing 100 to prevent the opening 144 from being in contact with ambient air, and thereby preventing the opening 144 from becoming clogged.
  • the tip 102 is movable by current supplied from the battery pack 52 to the solenoid 124. In the retracted position, the tip 102 is latched onto the permanent magnet 120. The tip 102 moves from the retracted position to the operative position by actuating the actuator 26 to activate the sprayer 10 to spray the paint. Actuation of the actuator actuates the battery pack 52 and directs current, via the controller 60, in a first direction through the solenoid 124 thereby creating a magnetic field that opposes the magnetic field of the permanent magnet 120. Accordingly, the tip 102 unlatches or releases from the permanent magnet 120.
  • the controller 60 may also include a timing feature that delays actuation of the pump 34 until the tip 102 is in the operative position such that paint does not spray until the tip 102 is in the operative position.
  • the tip 102 moves from the operative position to the retracted position.
  • Release of the actuator 26 disengages the battery pack 52 and therefore current runs in a second, opposite direction through the solenoid 124 thereby creating a magnetic field that attracts the magnetic field of permanent magnet 120.
  • the magnetic field pulls the tip 102 towards the permanent magnet 120 such that the tip 102 latches onto the permanent magnet 120 and the opening 144 of the tip 102 is moved into the housing 100 and out of alignment with the opening 104 in the housing 100.
  • the tip 102 is also rotatable within the housing 100 by 180 degrees.
  • the body 140 of the tip is rotatable about the longitudinal axis A such that the projection 148 moves between the first channel 108 and the second channel 112 via the third channel 116. That is, the body 140 rotates in a first direction (designated by arrow 150) to move the projection 148 from the first channel 108 to the second channel 112, and the body 140 rotates in a second, opposite direction to move the projection 148 from the second channel 112 to the first channel 108. Rotating the body 140 helps the user to clear clogs within the tip assembly 14.
  • the magnetic field is generated by a solenoid 124 and a permanent magnet 120, but the magnetic field may be generated by other configurations.
  • the magnetic field may be generated by an electro-permanent magnet (EPM).
  • EPM electro-permanent magnet
  • the configuration described relative to FIGS. 2-5 differs in that the solenoid 124 is positioned around an electro-permanent magnet 120 rather than adjacent the permanent magnet 120. Because the solenoid 124 surrounds the electro-permanent magnet, the direction of magnetization is towards the electro-permanent magnet.
  • the magnetic field of the electro-permanent magnet is also constant.
  • the magnetic field of the electro-permanent magnet is switched off by a pulse of current.
  • the electro-permanent magnet attracts the tip 102 to retain the tip 102 in the retracted position.
  • current supplied by the battery pack 52 through the solenoid 124 reverses the direction of the magnetic field such that the direction of magnetization is away from the electro-permanent magnet.
  • the tip 102 unlatches from the electro-permanent magnet. While unlatched, the tip 102 is subject to the force of the spring 128, which pushes the tip 102 upwards and the opening 144 of the tip 102 into alignment with the opening 104 in the housing 100.
  • the magnetic field may be generated by first and second rotating magnets 160, 164 that turn the magnetic field on and off, rather than the permanent magnet 120 and the solenoid 124 of FIGS. 2-5 .
  • the two diametrically magnetized magnets 160, 164 are positioned within the housing 100 of the tip 102 adjacent one another. When the tip 102 is in the retracted position, the north poles of the first and second magnets 160, 164 ( FIG. 7 ) are pointing in the same direction (e.g., aligned with one another).
  • the first and second magnets 160, 164 are magnetized in the same direction and pull the opening 144 of the tip 102 into the housing 100.
  • the direction of one of the first and second magnets 160, 164 is switched or rotated such that the north poles face in opposite directions (e.g., are spaced apart from one another).
  • the first and second magnets 160, 164 are magnetized in the opposite directions and release the tip 102 such that the spring 128 biases the tip 102 away from the magnets 160, 164 and the opening 144 of the tip 102 into alignment with the opening 104 in the housing 100.
  • FIGS. 9-12 illustrate a tip assembly 200 according to another embodiment of the invention.
  • the tip assembly 200 includes a housing 204 that is configured to be coupled to a paint sprayer 10 and a tip 208 that is positioned within and movable relative to the housing 204.
  • the housing 204 is coupled to a paint adapter 212, which is in communication with the outlet valve 38 of the paint sprayer 10.
  • the housing 204 includes an opening 202 and a first portion 220 coupled to a second portion 224.
  • a first chamber 228 extends through both the first portion 220 of the housing 204 and the second portion 224 of the housing 204 and defines a first axis C.
  • a second chamber 232 extends through the second portion 224 of the housing 204 and defines a second axis D that is perpendicular to the first axis C. Thereby, the second chamber 232 intersects with the first chamber 228.
  • the paint adapter 212 is coupled to housing 204 and fluidly coupled to the second chamber 232 and aligned with second axis D of the housing 204.
  • the tip 208, a tip bushing 240, a biasing mechanism 244 (i.e., spring), and a compression screw 248 are positioned within the housing 204.
  • the tip 208 includes an axis A, an opening 252 extending therethrough and a tip guide 256 coupled to one end.
  • the tip guide 256 prevents the tip 208 from rotating within the first chamber 228.
  • the tip bushing 240 has a channel 260 extending along one side.
  • the tip bushing 240 is positioned within the second portion 224 of the housing 204 such that one end of the tip bushing 240 abuts the first portion 220 of the housing 204.
  • the tip bushing 240 is positioned adjacent the first chamber 228 and the channel 260 of the tip bushing 240 extends parallel to the first axis C.
  • the compression screw 248 engages the tip bushing 240 on the opposite side of the channel 260.
  • the tip 208 is positioned in and movable relative to the first chamber 228 and the tip bushing 240. Accordingly, the axis A of the tip 208 is aligned with the axis C of the first chamber.
  • the tip 208 is movable between a first, operative position ( FIGS. 10 and 12 ) and a second, retracted position ( FIG. 11 ).
  • the tip 208 In the retracted position, the tip 208 is positioned between the first and the second chambers 228, 232 such that there is no fluid communication between the first chamber 228 and the second chamber 232.
  • the tip 208 engages (i.e., is seated against) an end of the first chamber 228 in the retracted position.
  • the opening 252 in the tip 208 is hidden within the housing 204 and spaced apart from the opening 202 in the housing 204 when the tip 208 is in the retracted position.
  • the opening 252 in the tip 208 is hidden within the housing 204 to prevent the opening 252 from being exposed to ambient air and from becoming clogged.
  • the tip 208 is retained in the retracted position by the bias of the spring 244.
  • the tip 208 In the operative position shown in FIGS. 10 and 12 , the tip 208 is spaced apart from the end of the first chamber 228 and the second chamber 232. Because the tip 208 is spaced apart from the second chamber 232, there is a pathway that allows fluid communication between the first chamber 228 and the second chamber 232. Also, the opening 252 in the tip 208 is aligned with the opening 202 in the housing 204. Therefore, paint can flow into and out of the tip 208 and via the pathway.
  • the tip 208 moves from the retracted position to the operative position when pressure is applied in the second chamber 232.
  • the tip 208 overcomes the bias of the spring 244 and moves to the operative position.
  • the pressure reduces and the bias of the spring 244 returns the tip 208 to the retracted position.
