Definitions

  • Figure 7 is an axonometric view of the two parts of the reverser assembly. Detailed description of the invention
  • This sub-assembly consists of a toothbrush handle 1, bridge 2, replaceable cartridge 3 with cartridge body 3.1 and a piston 3.2, plunger 5, pressure spindle 6, plunger coupling 7, rotary switch 10, rotary claw 12 and torsion spring 17.
  • a saddle is defined to mate with the cartridge gasket 18.
  • the cartridge gasket 18 is ring-shaped, having a central opening intended to allow the passage of fluid towards a predominantly axial passage inside the shank 19, stretching from the cartridge gasket 18 at one end to the bristle 20 at the other end.
  • the purpose of the cartridge gasket 18 is to prevent the leakage of fluid between the toothbrush handle 1 and the shank 19.
  • the elevation of the plunger 5 exerts pressure on the piston 3.2 which slides inside the body 3.1 of the replaceable cartridge 3, thus squeezing the fluid out of the replaceable cartridge 3 towards the passage extending axially through the toothbrush shank 19 and further towards the bristle and the membrane 21.
