A foam dispenser having a metal housing has a spool valve socket therein. A metal handle extends from the housing. A spool valve is disposable within the spool valve socket. A trigger couplable to the spool valve enables the spool valve to be rotated between open and closed orientations within the housing. The spool valve has internal channels for selectively passing liquids through the spool valve in the open orientation and not in the closed orientation. The spool valve also has a channel for selectively passing a gas through the spool valve in both the open and closed orientations.

A medical device including an application device with a first fluid path and a container movably attached to the application device. The container and the application device have a second fluid path therethrough, the container includes an inner chamber that is intermediate proximal and distal portions of the second fluid path, the inner chamber is fluidly isolated from the proximal portion of the second fluid path at a first position of the container, and the inner chamber is fluidly coupled to the proximal and distal portions of the second fluid path at a second position of the container. The first fluid path bypasses the container and the passage of fluid through the first fluid path is separately controllable from the passage of fluid through the second fluid path.

A handheld computer device is configured to selectively receive a plurality of fluid output values from a paint sprayer and configured to operate in an accessible mode in which the handheld computer device is in a first location where wireless connectivity, via a continuous or near continuous communication path, to at least one of a network server or the paint sprayer is accessible or operate in an inaccessible mode in which the handheld computer device is in a second location out of range of the continuous or near continuous communication path to at least one of the network server or the paint sprayer.

Provided are a cleaning cavity series for extrusion type coating, and a cleaning method. The cleaning cavity series for extrusion type coating includes a plurality of cleaning cavities, where the plurality of cleaning cavities form the cleaning cavity series, each of the plurality of cleaning cavities is provided with an inner cavity body, a cleaning cavity opening portion in communication with the inner cavity body is disposed on a side portion of each of the plurality of cleaning cavities, and cross-section outlines of the inner cavity bodies of the plurality of cleaning cavities are a series of curves with an equal chord length. The cleaning method includes: S1: evaluating an envelope line of a slurry that overflows from a lip portion of a coating head, and selecting one cleaning cavity from a cleaning cavity series to ensure that an enveloped area of the envelope line accounts for 30%-70% of the sectional area of an inner cavity body of the selected cleaning cavity; and S2: selecting a static cleaning method or a dynamic cleaning method to perform a cleaning operation on the coating head using the selected cleaning cavity from the cleaning cavity series. The cleaning cavity series for extrusion type coating, and the cleaning method using same have the advantages of having a simple structure, being convenient to apply, being low in implementation cost, and improving the cleaning effect, the coating quality and the production efficiency.

The present disclosure belongs to the technical field of mechanical spraying, and a color change block with detection feedback as well as spraying equipment are provided. The color change block with detection feedback comprises a cleaning agent valve module, a color change micro valve module, a mixing pipe module and a turbidity detection module which are connected in sequence. A complete collinear common channel is formed among these modules, and the wall surface of the common channel is a complete plane. The turbidity detection module is further connected to the control module and used for monitoring the turbidity of a medium flowing through the common channel in real time so as to determine whether the medium in the common channel meets a cleaning requirement or not and feed a determination result back to the control module, and then the control module switches other media to form a closed-loop control.

A robot for coating a vehicle body includes a coating head, a reservoir for storing coating material, a supply device capable of controlling the pressure of coating material flowing through a circulation path provided between the coating head and the reservoir, and an arm having a coating head and a supply device. The arm is a multi-axis arm having multiple arm members and a movable shaft connecting each arm member to each other, and it has a posture control means that controls the posture of the multiple arm members during coating of the vehicle body by the coating head to maintain the relative position of the coating head and the supply device at a constant level or to suppress fluctuations in the relative position within a predetermined allowable range.

The invention relates to an active substance supply system for an agricultural sprayer, having a main liquid circuit which comprises a reservoir for a main liquid and permits circulation of the main liquid, where the main liquid circuit comprises one or more distribution sections which are each configured to distribute to several dispensing elements a spray liquid to be dispensed, and a feed system which is connected to the main liquid circuit and in which the main liquid is mixed with at least one separately supplied active substance to form a liquid active substance mixture, where the active substance supply system is configured to introduce the active substance mixture into the one or more distribution sections at several places.

Devices and methods for dispensing beverage from a container, such as a wine bottle, using a dispensing device. The device may automatically purge at least one conduit used to deliver gas to a beverage container or to carry beverage from the beverage container in response to detecting that a dispensing operation is about to begin, or in response to detecting that a dispensing operation is complete. Visual or other displays may be provided to the user to indicate that the device is ready for use in dispensing, that a conduit is in fluid communication with the container interior and/or that the device is controlling components to dispense beverage.
