[0002] Water-fueled hydrogen-oxygen welding machine is a new type of welding equipment that uses the electrolysis of water to generate a hydrogen-oxygen mixture as fuel. Its core principle is to decompose water into hydrogen and oxygen and then perform welding through the high temperature of the hydrogen-oxygen flame.

[0003] In the existing technology, water-fueled hydrogen-oxygen welding machines require an external gas delivery hose to be connected to the gas outlet using a hose clamp. Once the pressure gauge on the welding machine shows that the pressure has reached the standard, it can be used. After use, the gas delivery hose needs to be removed.

Detailed Implementation

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0038] The embodiments of this utility model will be described below based on its overall structure.

[0039] First embodiment:

[0040] A water-fueled hydrogen-oxygen welding machine, please refer to Figure 1-6 The device includes a housing 1, which is specifically a water-fueled hydrogen-oxygen welding machine in the prior art. This application does not improve the gas generation of the hydrogen-oxygen welding machine, and its principle will not be described here. A first mounting groove 101 is provided inside the housing 1, and a first fixed cylinder 9 is fixedly installed at the center of the first mounting groove 101. A first rotating cylinder 10 is rotatably connected to the first fixed cylinder 9. A rotating wheel 7 for winding the gas guide hose is fixedly connected to the outer wall of the first rotating cylinder 10. A rotary joint 11 for connecting the gas guide hose is provided between the first fixed cylinder 9 and the first rotating cylinder 10.

[0041] Specifically, the rotary joint 11 includes a fixed part and a rotating part. The fixed part is fixedly connected to the first fixed cylinder 9, while the rotating part is fixedly connected to the first rotating cylinder 10. The rotary joint 11 is a common structure in the prior art for connecting two relatively rotating components, and its principle will not be elaborated here.

[0042] It also includes a cover 2, which is rotatably connected to the front of the casing 1, and has an opening groove 201 with a width greater than the diameter of the air guide hose at the end away from its own pivot.

[0043] For details regarding the above embodiments, please refer to [link / reference]. Figure 3-6 The machine casing 1 is provided with a second mounting slot 102, and a steel tank 5 is installed in the second mounting slot 102. Specifically, in the prior art, the hydrogen-oxygen welding machine produces welding gas from the gas outlet of the steel tank 5. The steel tank 5 is built into the second mounting slot 102 in the machine casing 1, which can effectively prevent the steel tank 5 from being bumped during the movement of the machine casing 1.

[0044] Specifically, the gas outlet of the steel tank 5 is connected to the rotary joint 11 inside the first fixed cylinder 9 through the first gas guide pipe 6. The rotary joint 11 is used to maintain gas communication. The rotating wheel 7 is equipped with a second gas guide pipe 16 along the diameter direction. One end of the second gas guide pipe 16 is connected to the rotary joint 11, and the other end is connected to the gas guide hose wound on the rotating wheel 7. The second gas guide pipe 16 is used to connect the gas guide hose wound on the rotating wheel 7. The gas guide hose wound on the rotating wheel 7 is also connected to a welding torch. The welding torch can be hung on the rotating wheel 7 when not in use.

[0045] Furthermore, a flame arrester 8 is connected between the first gas duct 6 and the rotary joint 11, which can effectively prevent deflagration accidents.

[0046] Second embodiment:

[0047] A water-fueled hydrogen-oxygen welding machine, please refer to Figure 1-6 Based on the first embodiment, the difference from the first embodiment is that a second fixed cylinder 13 is fixedly installed on the cover 2 in the direction of the first rotating cylinder 10. A second rotating cylinder 14 is rotatably connected inside the second fixed cylinder 13. A spring is provided between the inner wall of the second fixed cylinder 13 and the second rotating cylinder 14. Specifically, the spring is a common energy storage component between two coaxial rotating objects in the prior art. Its specific structure and principle will not be described in detail here. A mutually cooperating snap-fit ​​structure is provided between the second rotating cylinder 14 and the first rotating cylinder 10. The automatic winding of the air guide hose is achieved by the cooperation of the second rotating cylinder 14 and the spring.

[0048] For details regarding the above embodiments, please refer to [link / reference]. Figure 3-6 The second rotating cylinder 14 has slots 15 arranged in a ring at intervals, and the end of the first rotating cylinder 10 has inserts 12 arranged in a ring at intervals for inserting into the slots 15. When the box cover 2 is closed, the inserts 12 are all inserted into the corresponding slots 15. During the process of using the welding machine while the box cover 2 is closed, the excess length of the gas guide hose can be rolled back onto the rotating wheel 7, effectively avoiding the phenomenon of the gas guide hose tangling.

[0049] For details regarding the above embodiments, please refer to [link / reference]. Figure 1-2 The top of the cover 2 is provided with a locking structure that works in conjunction with the chassis 1, so that the cover 2 can be closed stably.

[0050] Specifically, after the cover 2 is closed, the top two sides of the chassis 1 are fixedly connected to fixing blocks 3. The fixing blocks 3 are slidably connected to pins 4. The pins 4 can pass through the fixing blocks 3 and the side wall of the cover 2 at the same time. The cover 2 can be locked and unlocked by inserting and removing the pins 4. After the cover 2 is closed, the chassis 1 is fixedly connected to fixing blocks 3 on both sides of the top. The fixing blocks 3 are slidably connected to pins 4. The pins 4 can pass through the fixing blocks 3 and the side wall of the cover 2 at the same time. After the pins 4 pass through the fixing blocks 3 and the side wall of the cover 2 at the same time, the cover 2 can be fixed. When the cover 2 is closed, the cover 2 does not contact the steel tank 5 and the rotating wheel 7.

[0051] In practical operation, this invention works as follows: after opening the box cover 2, the welding torch hanging on the rotating wheel 7 is taken out, and then the box cover 2 is closed. Pulling the gas guide hose will cause the rotating wheel 7 to rotate, and at the same time, the spring between the second rotating cylinder 14 and the second fixed cylinder 13 will store energy. When the tension of the gas guide hose disappears and the gas guide hose is in a relaxed state, the rotating wheel 7 will rotate in the opposite direction under the drive of the second rotating cylinder 14 to rewind the gas guide hose. This allows for quick access to the welding torch of the oxyhydrogen welding machine without the need for frequent disassembly and reassembly of the external gas guide hose.

[0052] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
