Ignitor

Abstract

In an igniter (1) which is ignited by operation of an actuator 20 and is provided with a lock member (25) which locks an actuator (20) when the igniter is unused and automatically returns to the locking position after use of the igniter, operability is improved and assembly is simplified. A lock member (25) which is moved in the igniting direction together with the actuator (20) is installed to be movable between a locking position and a lock release position. A lock portion (25b) of the lock member (25) extending in the locking direction interferes with an engagement portion of the igniter body to lock igniting action of the actuator (20). The lock member (25) is urged to the locking position by an urging member (26). With the lock released by operation of the lock member (25), the actuator (20) is slid together with the lock member (25) to ignite the igniter (1).

Description

technical field [0001] The present invention relates to an igniter in which flame is ejected from a gas nozzle by an ignition operation of an operating member. Normally, the locking member is engaged with the device body to lock the ignition; It is a mechanism that can release the ignition lock and start the ignition without disengagement. Background technique [0002] Although the igniter is a convenient appliance that can be easily ignited by pushing the fire rod into the operating member, it is required to be provided with a locking mechanism that cannot be accidentally ignited or accidentally ignited, so it has been proposed so far. Igniters with various mechanisms. [0003] For example, Japanese Unexamined Patent Publication No. 8-61673 discloses an igniter having a structure in which a locking portion provided so as to be movable in a direction intersecting with the moving direction of the operating member interferes with a part of the operating member. The locking m...

Problems solved by technology

[0005] However, in the former locking mechanism, since the locking member and the urging member composed of the spring that springs the locking member to the locking direction are assembled on the appliance body in different ways, it is difficult to assemble these members, which becomes Barriers to achieving increased productivity in mass production

In addition, multi-stage operation is required during the ignition operation, so there are also difficulties in operability.

[0006] The above-mentioned prior art has the problem that it is complicated work to assemble the two parts such as the locking member and the urging member in a different way from the operating member, and it is necessary to deform the urging member to a certain extent. It is difficult to efficiently assemble these parts into the appliance body with other parts

Moreover, the unlocking operation during the ignition operation in the normal use state is also because the releasing operation part is in the shape of a protrusion separated from the operating member, so the releasing operation and the pushing operation of the operating member are not consistent, and become multi-stage complicated. operation, it is sometimes difficult to achieve a stable ignition

[0007] In the latter locking mechanism, since its structure is such that the arm of the locking member extends along the moving direction of the operating member, it will interfere with the piezoelectric assembly inside the operating member, so there is relatively little space in the inner space of the operating member. In a narrow case, the movement range of the locking member is small, and it is difficult to obtain stable operability in the locked position and the unlocked position. In addition, since the interference portion between the arm and the piezoelectric unit is small, it is difficult to ensure a reliable locked state and In the released state, the function may be affected if the front end is worn out after repeated use
