Description

Technical Field

[0001] The utility model relates to the technical field of blowtorches, in particular to a piezoelectric ignition blowtorch. Background Art

[0002] A blowtorch is a newly emerging outdoor product and belongs to a kind of outdoor cooking utensil. It is a kind of ignition and heating tool derived from the existing butane gas cylinder. Outdoor cooking utensils generally refer to a stove head and fuel (butane gas cylinder) for cooking and boiling water outdoors, which are very convenient to carry. The blowtorch replaces the function of the stove head, liberates the flame from a fixed position, and is convenient for lighting a bonfire and roasting food on the spot.

[0003] A blowtorch usually needs to be detachably connected to a gas cylinder. A blowtorch generally includes an ignition switch, a nozzle, a flow regulating valve, a safety lock and other components. In addition to igniting when pressed, the ignition switch of the blowtorch also opens and closes the gas valve, and it requires continuous manual pressing. Once the hand is released, the ignition switch rebounds and resets, which in turn causes the on-off valve to reset, and then the gas delivery is interrupted and the flame goes out. Therefore, there are blowtorches with latches on the market. Pressing the latch can lock the switch to open the valve. However, the position of the latch is usually on the side of the ignition switch and requires the operation of the other hand, which is rather inconvenient. For this reason, we propose a piezoelectric ignition blowtorch. Summary of the Utility Model

[0004] To solve the above technical problems, an embodiment of the present application provides a piezoelectric ignition blowtorch, including a main body and a barrel provided on the main body, and further including:

[0005] A fixed sleeve, which is fixedly arranged on the main body;

[0006] An ignition switch, which is slidably arranged in the fixed sleeve and drives a piezoelectric igniter to ignite when moving;

[0007] A locking member, which is movably arranged in the ignition switch and is used to lock the ignition switch.

[0008] In some embodiments, the ignition switch includes a movable cylinder slidably arranged in the fixed sleeve. A chute is opened at the end of the movable cylinder, and a slider is slidably arranged in the chute. A driving plate is fixedly connected to the slider.

[0009] In some embodiments, the end face of the driving plate is arc-shaped and provided with anti-slip lines on the surface.

[0010] In some embodiments, the locking member includes a moving block fixedly arranged at the end of the slider. A locking rod is fixedly arranged on one side of the moving block. Locking grooves adapted for insertion and cooperation with the locking rod are formed in the side walls of both the fixed sleeve and the movable cylinder, and the distance between the two locking grooves is equal to the moving stroke of the movable cylinder. A return spring is arranged in the sliding groove, and two ends of the return spring are fixedly connected to the slider and the side wall of the sliding groove respectively.

[0011] In some embodiments, a chamfer is formed at the end of the locking rod.

[0012] In some embodiments, a fixed ring is fixedly arranged on the outer side of the gun barrel. A plurality of telescopic rods are fixedly connected to the fixed ring, and the plurality of telescopic rods are arranged in a circumferential array on the outer side of the gun barrel. An movable ring is fixedly arranged at the end of the telescopic rod.

[0013] In some embodiments, the end of the telescopic rod extends to the end of the gun barrel so that the position of the movable ring extends beyond the end of the gun barrel.

[0014] The utility model has at least the following beneficial effects:

[0015] In this piezoelectric ignition blowtorch, by providing a locking member on the ignition switch, the operation of the ignition switch can be achieved with one finger. Pressing the ignition switch can achieve the ignition action, and moving the locking member can keep the ignition switch in the pressed state. The user does not need to continuously apply force to keep the blowtorch continuously spraying fire. Moreover, when not in use, the locking member can also play an insurance role to prevent the blowtorch from being accidentally turned on. BRIEF DESCRIPTION OF THE DRAWINGS

When the driving plate 44 moves, it drives the slider 43 to move in the slide groove 42, and the slider 43 ensures the horizontal movement of the driving plate 44.

[0035] The end face of the driving plate 44 is arranged in an arc shape and has anti-skid grooves on the surface. When using the flamethrower, the user's index finger is buckled on the driving plate 44. Therefore, the end face of the driving plate 44 is arranged in an arc shape, which can fit the shape of the finger and cooperate with the setting of the anti-skid grooves to facilitate force application.

[0036] The locking member 5 includes a moving block 51 fixedly arranged at the end of the slider 43, a locking rod 52 fixedly arranged on one side of the moving block 51, a chamfered corner is provided at the end of the locking rod 52, and the side walls of the fixed sleeve 3 and the movable cylinder 41 are provided with locking grooves 53 which are plugged into and cooperate with the locking rod 52, and the distance between the two locking grooves 53 is equal to the moving stroke of the movable cylinder 41, so that the locking rod 52 can be inserted into the other locking groove 53 after the movable cylinder 41 moves, and a return spring 54 is arranged in the slide groove 42, and the two ends of the return spring 54 are respectively fixedly connected to the slider 43 and the side walls of the slide groove 42.
