DETAILED DESCRIPTION
[0013] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0014] like Figure 1 , Figure 2As shown, the safety flamethrower comprises a flamethrower body 1, the bottom side of the flamethrower body 1 is connected to an external gas tank, the front end of the flamethrower body 1 is provided with a flamethrower head assembly 2, the rear end of the flamethrower body 1 is provided with a connecting shell 3 connected to the external gas tank, the flamethrower body 1 and the connecting shell 3 have a flow pipe 4 that is interconnected and for gas to flow, a rotatable control valve ball 5 is arranged in the connecting shell 3 and at a position relative to the flow pipe 4, a control switch 6 for controlling the rotation of the control valve ball 5 is arranged on the connecting shell 3, a mounting groove 7 is opened on the connecting shell 3, a valve stem 8 is arranged on the control valve ball 5, and the valve stem 8 extends out of the connecting shell 3 and is controlled by the control switch 6, a fixing ring 9 is arranged on the connecting shell 3 and located in the mounting groove 7, a control rod 10 is fixedly arranged on the control switch 6, and the control rod 10 can move up and down on the fixing ring 9 and control the control valve ball 5, and a control assembly for returning the control rod 10 is arranged on the fixing ring 9.
[0015] In further detail, the control component is composed of a control part 11 and a return spring 12. The control part 11 is arranged on the fixed ring 9, and moves up and down on the fixed ring 9 through the action of the return spring 12. One end of the return spring 12 is connected to the control part 11, and the other end of the return spring 12 is connected to the connecting shell 3.
[0016] To further elaborate, when it is necessary to control the internal circulation pipeline 4, pressure is first applied to the control switch 6, the control rod 10 moves downward on the fixing ring 9, and the return spring 12 is in a compressed state, so that the groove 14 on the control rod 10 corresponds to the protrusion 13 on the valve stem 8, and the control valve ball 5 can be controlled to rotate, so as to achieve the purpose of controlling the internal circulation pipeline 4. When the flamethrower body 1 finishes working, the return spring 12 rebounds and drives the control member 11 to move outward, thereby controlling the control rod 10 to move outward, and the protrusion 13 is separated from the groove 14, so as to prevent other personnel from accidentally touching the opening of the flamethrower cavity, thereby improving the safety performance of the product.
[0017] To elaborate further, the control rod 10 is provided with a slide groove 15 for the fixing ring 9 to partially extend into, the valve stem 8 is fixedly provided with a protrusion 13, and the control rod 10 is provided with a groove 14 that cooperates with the protrusion 13, and the protrusion 13 and the groove 14 are both arranged in a cross structure.
[0018] To further elaborate, when pressure is applied to the control switch 6 , the protrusion 13 cooperates with the clamping groove 14 , so that the control rod 10 rotates the ball valve, thereby controlling the opening and closing of the flow pipe 4 .
[0019] To be more specific, the control switch 6 is fixedly connected to the flamethrower body 1 via a fixing member.
[0020] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
[0021] Although the present invention uses more terms such as the flamethrower body 1, the flamethrower assembly 2, the connecting shell 3, the circulation pipeline 4, the control valve ball 5, the control switch 6, the mounting groove 7, the valve stem 8, the fixing ring 9, the control rod 10, the control member 11, the return spring 12, the protrusion 13, the slot 14, the slide groove 15, etc., it does not exclude the possibility of using other terms. The use of these terms is only for more convenient description and explanation of the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
