In particular embodiments, the nozzle assembly comprises a disposable tip insert.
Claims19
An apparatus, comprising:
- a rechargeable power source;
- a motor and pump assembly coupled with the rechargeable battery;
- a fluid source;
- a nozzle assembly coupled with the motor and pump assembly and the fluid source;
- and
- an actuation mechanism having an first setting and a second setting coupled with the motor and pump assembly;
- wherein when the actuation mechanism is at the first setting, air is pumped by the motor and pump assembly to the nozzle assembly and fluid is provided by the fluid source to the nozzle assembly without passing through the motor and pump assembly, the fluid is mixed with the air at the nozzle assembly;
- and
- wherein the mixed air and fluid are dispensed by the assembly.
A method of operating a sprayer, the sprayer comprising a rechargeable power source coupled with a motor and pump assembly, the motor and pump assembly coupled with an actuation mechanism and a nozzle assembly, the nozzle assembly located at a nose section of the sprayer, the method comprising:
- fastening a disposable tip assembly to the nozzle assembly;
- coupling a disposable fluid source to the nozzle assembly;
- and
- activating the actuation mechanism, wherein activating the actuation mechanism causes fluid to flow from the fluid source to the disposable tip assembly, the motor and pump assembly to provide air to the disposable tip assembly, and a mixture of the air and the fluid to be dispensed from the disposable tip assembly;
- wherein fluid from the fluid source flows to the nozzle assembly without passing through the motor and pump assembly.
A kit, comprising:
- a sprayer assembly containing a rechargeable power source, a motor and pump assembly coupled with the rechargeable battery, a nozzle assembly coupled with the motor and pump assembly and the fluid source, and a trigger switch coupled with the motor and pump assembly;
- a disposable fluid container configured to be coupled with the sprayer assembly;
- a disposable tip insert configured to be threadably fastened to the nozzle assembly;
- and
- a tube coupling the disposable fluid container with the disposable tip insert.
