The present invention is applicable to the fields of spraying and chemical agent instruments, and provides a diaphragm pump sprayer comprising a housing in which a battery, a motor and a hose are arranged, with one end of the hose being connected with a sinking water inlet ball and the other end being connected with a spray head, characterized in that: a diaphragm pump for water pumping is also arranged within the housing, one end of the diaphragm pump is connected with the hose and the other end is connected with the spray head, and the diaphragm pump is driven for water pumping by the battery and the motor. The diaphragm pump sprayer provided in the present invention realizes the purpose of pumping and spraying liquid by the diaphragm pump sprayer. The diaphragm pump, which has high chemical corrosion resistance and high working efficiency, is employed as a substitute for existing gear pumps, piston pumps and peristaltic pumps in the present invention.

A dispensing assembly for dispensing fluid generally includes a container having a handle located toward an upper portion of the container, and a sprayer having arms extending away from the sprayer. The arms of the sprayer define a channel configured to receive at least part of the handle of the container within the channel to thereby couple the sprayer to the container. Such a dispensing assembly can be made by forming the container with a handle located toward an upper portion of the container, and forming the sprayer with the arms such that the arms can be used to couple the sprayer to the handle of the container, where the arms extend away from the sprayer and define the channel for receiving at least part of the handle of the container into the channel.

Exemplary embodiments of manual dispensers and actuating mechanisms are disclosed herein. An exemplary dispenser includes a housing, a receptacle for receiving a container of fluid and an actuating mechanism for causing fluid to be dispensed from the container. The actuation mechanism has a first pivot arm having a pivot point on a first end and a cam on a second end and a second pivot arm having a pivot point a first end and a curved contact surface on a second end. The actuating mechanism includes a pushbar. One of the first and second pivot members is connected to the pushbar. When the pushbar is pushed inward, the cam is configured to travel along the curved contact surface. Movement of the cam along the curved contact surface moves the engagement mechanism upward and downward in a substantially linear motion when the engagement mechanism is connected to a pump to cause the pump to prime with fluid and dispense the fluid.

The invention relates to a paint spraying unit which includes a paint pump, a paint storage container, a paint spraying device, a paint line and a drive device, where the drive device drives the paint pump and the paint pump conveys paint out of the paint storage container through the paint line to a nozzle of the paint spraying device. In this connection, the drive device includes a compressed air rotation motor as the motor.

A dispensing assembly (100) for dispensing fluid generally includes a container (104) having a handle (126) located toward an upper portion of the container (104), and a sprayer (106) having an arm extending away from the sprayer. The arm (142) of the sprayer (106) defines a channel (158) configured to receive at least part of the handle (126) of the container (104) within the channel (158) to thereby couple the sprayer (106) to the container (104). Such a dispensing assembly (100) can be made by forming the container (104) with a handle (104) located toward an upper portion of the container (104), and forming the sprayer (106) with the arm (142) such that the arm (142) can be used to couple the sprayer (106) to the handle (126) of the container (104), where the arm (142) extends away from the sprayer (16) and defines the channel (158) for receiving at least part of the handle (126) of the container (104) into the channel (158).

A pressure washer includes a motor configured to drive a pump, a frame having first and second end portions, a handle having first and second end portions, and a rotating joint rotatably coupling the first end portion of the handle to the second end portion of the frame. The rotating joint includes a locking mechanism to selectively lock the position of the handle relative to the frame. The handle rotates between a storage position and an extended position. In the storage position, the second end portion of the handle is positioned near the first end portion of the frame such that the motor and the pump are located within a volume defined by the first and second end portions of the handle and the frame. In the extended position, the second end portion of the handle is spaced apart from the frame.

A fluid sprayer comprises a fluid source, a spray tip, a pump, and an outlet check value assembly. The spray tip has a fluid outlet aperture, and the pump is disposed to pump fluid from the fluid source out the fluid outlet aperture. The outlet check valve is disposed between the pump and the spray tip, and includes a sealing element, a seat, and a polymer housing. The seat is aligned to receive the sealing element, and the polymer housing is overmolded about the seat.

A rotary part of a pump (200) is connected to a body member (110) to be rotatable together. When the body member is attached to a main shaft (20) of a machine tool (10), a rotation stopping pin (310) of a rotation stopping device (300) fits in a fitting hole (41) of the machine tool and abuts on a wall surface (41a) of the fitting hole, whereby the rotation stopping pin and a rotation stopping lever (340) axially move against an elastic force of a spring (320) and the rotation stopping lever disengages from an engagement hole (113) in the body member such that the body member becomes rotatable relative to a support part (150, 160) that rotatably holds the rotary part. A force detecting sensor (50) outputs a force detection signal indicating a force with which the rotation stopping pin is pressing against the wall surface.

A modular sprayer system for use with heavy-lift unmanned aerial vehicles includes a liquid storage tank for receiving and storing any type of agricultural products. A mounting unit is located along the top of the tank and includes hardware for securing the system to a UAV. Skid-type landing gear is permanently secured to the outside of the tank, and an electric pump is disposed within the tank. The location of the pump dampens movement of fluid within the tank during flight. One or more elongated booms are in fluid communication with the pump and terminate into dispensing units having one or more nozzles for releasing the fluid. A control unit is in electrical communication with one or both of the UAV to which the system is secured and a system operator. A tank level sensor and imaging systems are communicatively linked with the control unit.
