Description

  The present invention relates to an aerosol product in which an aerosol composition filled in an aerosol container is sprayed as a fine mist spray and the spray can be charged by induction.

  As background art, the electrostatically charged aerosol spray system described in patent document 1 is illustrated. This spray system is for electrically charging an aerosol spray. As shown in FIG. 17, the actuator 120 of this spray system has an inductor 134 at a position adjacent to the spray nozzle 118 to induce charge in the atomized fluid. Charge to the inductor 134 is supplied by the piezoelectric crystal 146 that is stressed by the movement of the actuating member 126. Since charging of the inductor 134 uses negligible power, no other power source is required. The piezoelectric crystal 146 can be stressed continuously, such as by pressing, or intermittently, such as by striking. When providing intermittent stress, the electrical circuit includes a switch between the crystal and the inductor 134, which is open when the valve is open and electrically isolates the inductor 134 during spraying.

JP 9-504735 A

  However, when the actuator 120 is removed from the container 112, for example, when the empty container 112 is replaced, the operating member 126 is pushed down with the body touching the inductor 134 due to carelessness of the user. In other words, there is a problem of electric shock. This problem similarly occurs when a battery is used instead of the piezoelectric crystal 146 as a power source for supplying power to the inductor 134. Moreover, when a battery is used, the user may be similarly electrocuted when replacing the battery.

In order to solve the above problems, the aerosol product of the present invention is:

The spraying device and the induction charging device are configured as a spraying charging module so that they can be attached to and detached from the aerosol container.
The jet charging module is removed from the aerosol container, and a detection unit that detects whether the spray charging module is attached to or removed from the aerosol container depending on whether it is in contact with the aerosol container. And a startup preventing unit configured to prevent startup of the induction charging device in accordance with the operation of the injection button.

  According to this configuration, since the injection device and the induction charging device are modularized as the injection charging module, the injection device and the induction charging device can be integrally attached to and detached from the aerosol container. The aerosol container can be easily replaced when the composition is used up. In addition, when the injection charging module is detached from the aerosol container, the detection unit and the activation prevention unit prevent the induction charging device from being activated in response to the operation of the injection button, thereby preventing an electric shock of the user. can do.
