Description

  The present invention relates to an electric writer that includes a heating wire for igniting the tip of a cigarette, a battery, and an energization switch and energizes the heating wire from the battery via the energization switch.

JP-A-2005-76929 JP, 2008-286510, A The battery type writer of patent documents 1 is provided with the slide member 6 inside the writer, and the operation part 61 integral with the slide member is exposed to the outside on the upper surface side of the outer case. However, when the operating portion 61 is slid, the slide member 6 is retracted from a position that prevents the energization switch 5 from being closed to a position where it can be closed, and an ignition window that looks into the heating wire 4 is exposed. That is, the slide member 6 is provided inside the outer case.

  In the portable ignition device described in Patent Document 2, the upper end portion of the cylindrical heating element cover 15 viewed through the heating element 10 is always exposed to the outside on the upper surface side of the outer case, and on the side surface side of the outer case. When the switch button 30 exposed to the outside is slid, the heating element 10 is energized to generate heat.

  Since the battery-type writer described in Patent Document 1 includes the slider 6, protection of the heating wire 4 inside the ignition window and prevention of inadvertent contact of a finger with the ignition window portion that has become hot after use of ignition are prevented. Moreover, unintentional heat generation of the heating wire 4 due to careless or erroneous operation of the energization switch 5 is prevented, and the safety of the writer is high. However, since the slider member 6 is provided inside the outer case and the slide member 6 slides the ignition window inside the writer, dirt such as tobacco waste, carbide and ash near the ignition window adheres to the slider member 61 and the writer. Dirty inside. This makes it difficult for the slider 61 to slide, and it becomes difficult to maintain safety by the slider member 6. If the outer case is not disassembled, the slider 61 and the inside of the writer cannot be cleaned, which requires time and effort for cleaning. In the portable ignition device described in Patent Document 2, since the ignition window that looks into the heating wire 4 is always exposed and the switch button 30 is slid, the heating wire 4 generates heat. Therefore, the heating wire 4 generates heat due to unintended sliding. Even after the cigarette is lit, even if the switch is turned off, the heating wire 4 and its surroundings are hot and exposed to the outside of the writer, so the safety is low.

  The first object of the present invention is to increase the safety of the electric writer, and the second object is to facilitate cleaning of the heating wire.

  The upper lid 1 is attached to the tip of the upper case 5 at one end thereof with a pin 4 so as to be rotatable about it. That is, it is hinged to the upper case 5. The pin 4 passes through the hinge spring 3 (a torsion coil spring in this example) that is a first elastic member. One end of the torsion coil spring 3 is engaged with the upper case 14 w and the other end is engaged with the upper lid 1. The torsion coil spring 3 forces the upper lid 1 to rotate with respect to the upper case 5 in a direction to stand up from the upper case 5. When the top lid 1 is closed, the top end (free end) of the top lid 1 is engaged with the slide block 6 of the lock member, which prevents the top lid 1 from being opened (stand-up rotation). When the lock button 2 integrally coupled to 6 is pulled away from the upper lid 1, the slide block 6 is detached from the upper lid 1, and the upper lid 1 is driven to rotate upright by the repulsive force of the torsion coil spring 3.

  Between the battery 17 and the upper case 5, an electric circuit board 9 that is electrically connected by fitting contact is inserted, and a connector 9 c, a battery 17, a heating wire 14 w, and an energizing switch ( 11) is electrically connected by mechanical fitting. This mating connection replaces the solder connection and was adopted to avoid environmental problems during disposal.

  A round hole (opening) is opened in a portion of the electric circuit board 9 where the electric heating board 14 is arranged, and the upper end portion of the sleeve 18a of the lower case 18 is inserted into the round hole, and the electric heating board connected to the electric circuit board 9 is provided. 14 is located under the inspection hole 18b of the sleeve 18a. The tip guide 10 attached to the electric heating substrate 14 via the heat-resistant spacer 13 and the crater plate 12 enters the round hole near the tip (hinge) of the upper case 5 and is closed by the upper lid 1 of the upper case 5. It is the same height as the bottom of the dent. The push button of the energization switch 11 protrudes above the bottom surface at the rear end portion (near the lock button 2) of the bottom surface of the recess. In order to prevent the push button 1 from being pressed by the upper lid 1, a round hole with a bottom is opened at the position opposite the push button of the upper lid 1 (FIG. 3). At the tail end of the upper case 5, there is an opening through which the connector 9 c looks and a connector cover 8 that closes the opening. The user can charge the battery 17 by opening the connector cover 8 and connecting a charger to the connector 9c.

  At the tip of the electric circuit board 9, there is a pin hole through which the insulating operation pin of the upper lid switch 15 passes, and there is also a pin hole that matches the pin hole on the bottom surface of the recess of the upper case 5, The operation pin of the upper lid switch 15 passes through these pin holes and protrudes upward from the bottom surface of the recess. A lower end portion of the operation pin of the upper lid switch 15 has a large-diameter metal (conductor) sleeve, and this metal sleeve is a switch spring 16 (in this example, a compression coil spring) supported by a lower case, and an electric circuit board. Underneath 9, it is forced upward to contact the pair of switch conductors of the circuit board 9. In other words, the spring is pressed upward to electrically connect (turn on) the pair of switch conductors.

  As shown in FIG. 1A, when the upper lid 1 is closed, the operation pin of the upper lid switch 15 is pushed down so that the metal sleeve is separated from the pair of switch conductors of the electric circuit board 9, and the upper lid switch 15 Is open (off), but when the upper lid 1 is opened as shown in FIGS. 2 and 3, there is no force to hold down the operation pin, so the metal sleeve is pushed up by the repulsive force of the switch spring 16 and a pair of switch conductors And the upper lid switch 15 is switched to the closed (on) state. Since the heating wire 14w is energized from the battery 17 through the series connection circuit of the energization switch 11 and the upper lid switch 15, even if the energization switch 11 fails and is normally closed (on), the upper lid switch 15 is open. If the upper lid 1 is closed, the heating wire 14w does not generate heat. Even if the foreign matter is caught and the upper lid 1 is closed and the energization switch 11 is closed, the heating wire 14w is not energized because the upper lid switch 15 is open.
