Multicomponent dispenser

A dispenser for dispensing a mixture of viscous materials, the dispenser comprising:

• a stock portion defining a handle to enable a user to hold the dispenser by gripping the handle, thereby to operate the dispenser as a hand-held dispenser;
• a holder portion secured to the stock portion to hold the materials in respective barrels relative to the stock portion;
• a first electric motor housed by the stock portion;
• a dispensing mechanism coupled to the first electric motor to dispense the materials from the holder portion;
• a mixer holder securable to the holder portion to guide the materials from their barrels to a respective outlet port for fluidically coupling to inlet ports of a mixer attachment;
• and
• a second electric motor coupled to the mixer by a planetary gearbox and a gear set, when the mixer attachment is attached to the outlet ports, to actuate the mixer attachment;
• and
• a controller configured to control the first electric motor as a variable speed motor based on a magnitude of a user input and to control the second electric motor as a fixed speed motor by switching the second motor on and off based on the presence of the user input.

• a stock portion coupled to the holder and defining a handle portion to enable a user to hold the dispenser by gripping the handle, thereby to operate the dispenser as a hand-held dispenser;
• a first electric motor coupled to the dispensing mechanism to drive the dispensing mechanism;
• a mixer holder for holding a mixer attachment relative to the holder portion to receive the materials for mixing inside a mixer;
• a mixing mechanism for coupling to the mixer attachment when the mixer attachment is attached to the mixer holder;
• a second electric motor coupled to the mixing mechanism by a planetary gearbox and a gear set for driving the mixer attachment when the mixer attachment is attached to the mixer holder;
• and
• a controller configured to operate the first electric motor as a variable speed motor based on magnitude of a user operational input and to operate the second electric motor as a fixed speed motor upon the presence of user input.
