A unit of the piston actuation unit has a support arm (80) cooperating with a transversal part of the level Pj such that a manual actuation of a movable part (4) drives an axial displacement of the piston to spray a liquid. The compression unit is formed by a spring exerting a pressure on the piston and an axially compressible material block.

Description

RECHARGEABLE VAPORIZER 5 FIELD OF THE INVENTION

  The invention relates to the field of vaporizers for liquid cosmetic products, for example perfume or toilet water vaporizers.

  It relates more particularly to the field of low capacity sprays relative 1 o, refillable vaporizers from a large capacity bottle, said primary reservoir.

STATE OF THE ART

  Rechargeable vaporizers are already known.

  The older rechargeable vaporizers use a "venturi" type device operated with a pear so as to create a flow of sucking air and spraying the liquid contained in the vaporizer.

  The newest rechargeable vaporizers use a pump as a propulsion mechanism for the liquid.

  These vaporizers are usually refilled by unscrewing the "Venturi" device or the pump and reloading the body of the vaporizer.

PROBLEMS POSED

  On the one hand, many refillable vaporizers have a size and / or fragility such that they are intended for use in the bathroom, while there is a need to have rechargeable refreshing small, suitable to be carried with oneself, typically on oneself or in a purse.

  On the other hand, especially in the case of pump vaporizers, the spray is related to the manual pressure exerted on a push button actuating the pump. However, this manual pressure is very variable as regards both the force exerted and the speed at which it is exercised. As the quality of the vaporization, the fineness of the droplets of liquid product sprayed, will depend on these two parameters, as well as the quality of the spray is very random, and variable from one person to another.

  The invention aims to solve these problems.

DESCRIPTION OF THE INVENTION

  This vaporizer according to the invention solves the problems posed.

  Indeed, this vaporizer comprises a compression means which exerts on the piston a force F independent of the person who will actuate said activation means. Therefore, regardless of the user, regardless of strength or age, the quality of the spray will be the same.
