Definitions

  • Small household appliances for various purposes such as hairdryers, mixers carpet sweepers etc are well known and widerspread they are all provided with a plug connecting to an electric socket having an electric cord which before being connected to the driving motor of the aplliance it refers to fixed contact to a current switch working by pushbutton or lever.
  • the present invention refers to a new type of device which allows or interrupts the current flow of the motor driving small household aplliances and precisely those that are constantly handled by the user such as hair dryers mixers, polishers vacuum cleaners or mechanisms operating regulating steam flow in irons etc.
  • the invention consists in having foreseen the connection of the two parts of the casing constituting the external body of the appliance by means of a hinge so allowing the two corresponding parts of the handle to meet or separate rather than having the parts fixed together and using a microswitch instead of a regular trumbler switch of the known type to interrupt the electric flow coming from the plug of the appliance, said microswitch being contained inside the handle of the appliance and operated by the pressure of the hand practised on the outer part of the handle capable of opening and closing enough to allow the contacts of said microswitch arranged inside the handle to connect or separate.
  • 1 shows a hairdryer made up by an external casing having two parts 2 and 3 of moulded material containing in its upper part the electroventilator and the heating battery not illustrated in the drawings considering that they are well known in the field.
  • the device is completed with a held by one of the two parts 3 constituting the body of the appliance having edges of a shape and size fit to cover the inferior tooth of the half part 2 even when the two half parts are in a separated position.
  • the two half parts can rotate around the hinge 4 and assume when necessary the position of fig. 1: half parts separated in correspondance to the handle and consequently are opened the contacts of the microswitch; and respectively of fig. 2: half parts connected and consequently the contacts of the microswitch closed.
  • the "off" position, that of fig. 1 which involves the two half parts separated and the contacts of the microswitch opened in obtained due to the opening of the handle of the half part 2 operated by the same spring contained in the microswitch 6, as shown in the example here illustrated, or foresseing the application of a spring in the handle of the two half parts 2 and 3 in a fit position which has the function of keeping the two half handles 2 and 3 separated.
