Definitions

  • the invention relates to a push-type electronic lighter, in particular to a safety type lighter.
  • the push-type electronic lighter in the prior art includes a casing, a head cover, a gas tank, a piezoelectric device, a gas core device, an air tube and a seesaw.
  • the head cover When the head cover is rotated and opened, the head cover depresses the piezoelectric device, so that the piezoelectric device generates a spark, which in turn ignites the gas and generates a flame.
  • the opening of the head cover and the ignition operation of this structure are performed simultaneously, that is, as long as the head cover is opened, a flame will be generated, so it is easy to cause automatic ignition by accidentally pressing the head cover and eventually cause a fire.
  • children's blind play is also prone to accidents. Summary of the Invention
  • the object of the present invention is to provide a safety type lighter, which can prevent unintentional automatic ignition, thereby eliminating accidents.
  • a safety lighter includes a casing with an open upper end, a gas box installed in the casing, and a piezoelectric device. , A gas guiding core device, an ignition port and a seesaw, and a head cover which is relatively rotatably mounted on the upper end of the gas tank.
  • the guide plate also includes an elongated hole in the upper part of the gas tank; a vertically extending guide plate integrally formed on the inside of the top of the head cover; a lower end of the guide plate is provided with a horizontal pin, and the horizontal pin passes through the elongated hole;
  • the lateral side of the guide plate also has a convex end that keeps contact with the top of the piezoelectric device.
  • a stopper for restricting the rotation of the head cover is provided on the upper side of the gas tank.
  • a safety type lighter which includes a casing with an open upper end, a middle frame fixedly installed on one side of the open end of the casing, and a gas tank installed in the casing.
  • the extended guide plate is provided with a horizontal pin at the lower end of the guide plate, and the horizontal pin passes through the elongated hole in the gas tank and the middle frame.
  • the lateral side of the guide plate also has a convex end that keeps contact with the top of the piezoelectric device. .
  • a stopper for restricting the rotation of the head cover is provided on the middle frame.
  • the invention has the advantage that when the lighter is turned on and ignited, the head cover cannot continue to rotate after hitting the stopper on the gas tank or the middle frame, thereby limiting the piezoelectric action of the head cover to the piezoelectric device. At this time, only When it is necessary to ignite consciously, press the head cover vertically downwards, so that the pins in the horizontal position move downward along the elongated holes in the gas tank (and the middle frame), so as to depress the piezoelectric device and generate a flame. This prevents fires caused by unintentional auto-ignition. In addition, because a strong spring is installed in the piezoelectric device, the force required for piezoelectric ignition is increased, making it difficult for children to press the piezoelectric device with sufficient finger force even when the head cover is opened. This can eliminate accidents.
  • FIG. 1 is a partial cross-sectional view according to a preferred embodiment of the present invention, in which the head cover is in a closed state;
  • FIG. 2 is a view similar to that shown in FIG. 1, where the head cover is in an open state;
  • FIG. 3 is a partial cross-sectional view of a safety type lighter provided with a middle frame, wherein the head cover is in a closed state; and FIG. 4 is a view similar to that shown in FIG. 3, wherein the head cover is in an open state.
  • this safety type lighter includes a casing 13 with an open upper end, a gas tank 6 installed in the casing 13, a piezoelectric device 11, a gas core device 5, and an ignition port 2.
  • a seesaw 12 and a head cover 1 rotatably mounted on the upper end of the gas tank, the above structure is well known in the prior art, so it will not be described in detail here.
  • An improvement of the present invention is that an elongated hole 4 is provided in the inside of the casing 13 such as the upper part of the gas tank 6; and the inside of the top of the head cover 1 integrally forms or fixes a vertically extending guide plate 7, and a lower end of the guide plate 7 A horizontal pin 3 is provided, and the horizontal pin 3 passes through the elongated hole 4 so that the head cover 1 is rotatably mounted on the gas tank 6.
  • a lateral side of the guide plate 7 has a convex end 9 that keeps contact with the top of the piezoelectric device 11, and an upper side of the gas tank 6 is also provided with a stopper 8 that restricts the head cover 1 from rotating.
  • FIG. 1 shows the head cover 1 in the closed position, and the horizontal pin 3 is located at the upper part of the elongated hole 4;
  • FIG. 2 shows the head cover 1 in the open position, and the horizontal pin is located at the lower part of the elongated hole 4.
  • a strong spring 10 may be installed in the piezoelectric device 11.
  • FIG. 3 shows the head cover 1 in the closed position, and the horizontal pin 3 is located at the upper part of the elongated hole 4;
  • FIG. 4 shows the head cover 1 in the open position, and the horizontal pin is located at the lower part of the elongated hole 4.

Abstract

La présente invention se rapporte à un briquet de sécurité comportant un boîtier doté d'une ouverture supérieure, un réservoir de combustible disposé dans le boîtier, une unité piézo-électrique, un manchon de guidage du gaz, une pointe d'allumage, un levier et un couvercle monté rotatif en partie supérieure du réservoir de combustible. Ce briquet de sécurité présente par ailleurs une longue encoche ménagée sur la partie supérieure du réservoir de combustible, un panneau de guidage qui est intégré à la partie supérieure interne du couvercle et fait saillie suivant la verticale, un ensemble de broches disposé horizontalement en partie inférieure du panneau de guidage et accouplé à la longue encoche, un organe de blocage situé sur le trajet en rotation du couvercle lorsque celui-ci est déverrouillé, un ressort installé dans l'unité piézo-électrique et un renflement situé sur un côté du panneau de guidage en direction transversale pour assurer le contact avec la partie supérieure de l'unité piézo-électrique. Le briquet de la présente invention permet d'éviter tout allumage involontaire et donc tout accident avec des enfants manipulant ledit briquet.
