[0041] The existing method of melting and cleaning wax is to tie a steam hose to a wooden stick. The operator holds the wooden stick and inserts the steam pipeline into the oil pipe to melt the wax and clean it. During the wax melting process, one person needs to hold the wooden stick at all times. This method consumes a large amount of steam for melting wax, takes a long time, has poor wax cleaning effect, has high labor intensity for employees, and poses safety hazards during operation.

[0042] In view of this, the present invention provides a fuel pipe inner wall cleaning gun to alleviate the above problems. The device includes a main body 100 and a fixing device 200 provided on the main body 100;

[0043] One end of the body 100 is detachably connected to the nozzle 300, and the other end is detachably connected to the steam pipe 400;

[0044] The fixing device 200 has a contracted state and an expanded state. In the contracted state, it can be inserted into the oil pipe, and in the expanded state, it can be engaged with the inner wall of the oil pipe.

[0045] When using this device for wax melting and cleaning operations, first select a suitable nozzle 300 according to the actual conditions on site, then connect the steam pipe 400 to the main body 100, then set the fixing device 200 to a contracted state, and then insert the end of the main body 100 on which the nozzle 300 is installed into the oil pipe, and then set the fixing device 200 to an expanded state, so that the fixing device 200 is tightly clamped to the oil pipe, and steam can be introduced to melt the wax. Compared with the existing technology, the operator does not need to hold the wax melting equipment for a long time, which reduces the operator's labor intensity, and the operator can always keep a long distance from the oil pipe during wax melting, avoiding personal injury caused by splashing of steam and harmful substances in the oil pipe during operation.

[0046] Regarding the shape and structure of the fixing device 200, Figure 1 As shown:

[0047] The fixing device 200 includes a pressing handle 210 and a spring 220;

[0048] One end of the pressing handle 210 is rotatably connected to the body 100 via a rotating shaft;

[0049] A first support block is provided on the side of the pressing handle 210 away from the rotating shaft;

[0050] A second support block is provided at a position of the body 100 corresponding to the first support block;

[0051] The spring 220 is respectively sleeved with the first support block and the second support block;

[0052] The spring 220 is a compression spring, and is capable of always driving the pressing handle 210 to move away from the main body 100 .

[0053] Specifically, the main body 100 can be made of stainless steel or other corrosion-resistant materials, and a fixed block is welded on its side wall. A rotating shaft is provided in the fixed block, and an opening matching the rotating shaft is provided at one end of the pressure handle 210. The spring 220 pushes the pressure handle 210 upward in the initial state.

[0054] Regarding the structure of the pressing handle 210, Figure 1 As shown:

[0055] The pressing handle 210 includes a first end 211 and a second end 212;

[0056] There is an angle of 150° between the first end 211 and the second end 212;

[0057] There is an angle of at least 30° between the first end 211 and the body 100;

[0058] A first latching tooth 213 is provided on a side of the first end 211 facing away from the body 100;

[0059] A second latching tooth 110 is provided on one side of the body 100 away from the first end 211;

[0060] The first latching tooth 213 is provided corresponding to the second latching tooth 110;

[0061] A handle 120 is provided on one side of the body 100 away from the nozzle 300;

[0062] The handle 120 and the body 100 have an included angle of 150°.

[0063] Specifically, the handle 120 and the pressure handle 210 are provided on the same side of the body 100. To facilitate the connection of the steam pipe 400, the handle 120 and the body 100 have an angle of 150 degrees. If the pressure handle 210 is a straight rod, the pressure handle 210 and the handle 120 are parallel before use. After the pressure handle 210 is pressed, it moves toward the direction of the handle 120, making the pressure handle 210 and the handle 120 too close to each other, which is inconvenient to use. Therefore, the pressure handle 210 is bent in the middle to make the integrated The straight rod is bent into two parts, namely a first end 211 and a second end 212, and the second end 212 is bent in a direction away from the handle 120. In this way, when in use, there is always an appropriate distance between the handle 120 and the pressure handle 210, which is convenient for use; when the device enters the oil pipe, under the action of the spring 220, the first latching tooth 213 moves in a direction away from the second latching tooth 110, so that the first latching tooth 213 and the second latching tooth 110 are respectively engaged with the inner wall of the oil pipe, so that the device is stuck in the oil pipe.

[0064] In this solution, the nozzle 300 is designed to be detachable, and there is a certain gap at its connection. In order to avoid leakage that reduces the wax melting effect, a sealing ring is provided at the connection between the nozzle 300 and the body 100.

[0065] In this solution, a horse tooth buckle is provided at one end where the main body 100 is connected to the steam pipe 400. The steam pipe 400 and the main body 100 are detachably connected. After the wax melting is completed, the steam pipe 400 needs to be disassembled. In order to indicate the firmness of the connection, the steam pipe 400 can be fixed with a clip after being inserted into the horse tooth buckle.

[0066] This solution has at least the following beneficial effects:

[0067] This solution provides a fuel pipe inner wall cleaning gun to address the various shortcomings of existing wax melting and cleaning methods. Traditional wax melting and cleaning methods require operators to tie a steam hose to a wooden stick and then insert the stick into the fuel pipe for cleaning. This method presents several problems: First, the operator must manually hold the stick for a long time, which is labor-intensive and inconvenient. Second, the wax melting process requires a large amount of steam, resulting in high steam consumption and poor cleaning results. Third, the operation presents safety hazards, such as the splashing of steam and harmful substances in the fuel pipe, which can cause personal injury.

[0068] To address these issues, this proposal introduces a new oil pipe inner wall cleaning gun. This device comprises a main body 100, a fixture 200 mounted on the main body 100, and a nozzle 300 and a steam pipe 400 detachably connected to the main body 100. The fixture 200 has a contracted state and an expanded state, allowing it to enter the oil pipe in the contracted state and tightly engage the inner wall of the oil pipe in the expanded state. To use the gun, the operator simply selects the appropriate nozzle 300, connects the main body 100 to the steam pipe 400, then retracts the fixture 200, inserts the nozzle into the oil pipe, and finally expands the fixture 200, securing it tightly to the inner wall of the oil pipe. This allows the operator to begin wax melting and cleaning.

[0069] This device offers significant advantages: First, operators no longer need to hold the device for extended periods, significantly reducing labor intensity and avoiding potential safety hazards during operation. The more secure connection between the cleaning gun and the oil pipe allows operators to maintain a safe distance from the oil pipe, reducing the risk of splashing steam and hazardous substances. Second, improvements to the fixture 200 ensure a more stable attachment of the cleaning gun to the oil pipe, enhancing cleaning effectiveness and efficiency. Therefore, this improvement not only improves the safety and effectiveness of cleaning operations but also optimizes the operator's working environment.
