[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a clean steam combustion generator, comprising an outer shell 1, providing installation space and protection for internal components. A heat-conducting plate 3 is fixedly connected to the middle of the inner wall of the outer shell 1 to transfer heat generated by combustion below to the upper area. A heat insulation layer 4 is fixedly connected to the bottom of the inner wall of the outer shell 1 to reduce heat loss from the combustion area to the bottom. A natural gas pipeline 5 is connected to the left side of the outer wall of the outer shell 1 to introduce external natural gas into the device to provide fuel for combustion. The right end of the natural gas pipeline 5 passes through the outer shell 1 and the heat insulation layer 4 and is fixedly connected to a natural gas nozzle 6. The natural gas nozzle 6 sprays natural gas in a suitable manner for combustion. An igniter 7 is fixedly connected to the top center of the nozzle 6 to ignite the natural gas ejected from the nozzle 6. An air guide shroud 8 is fixedly connected to the top of the nozzle 6 to guide outside air in and mix it thoroughly with the natural gas, making combustion more complete and improving combustion efficiency. A water tank 9 is fixedly connected to the rear side of the outer wall of the outer casing 1 to store water for steam generation, providing a water source for steam generation. A heating pipe 10 is fixedly connected to the top of the heat-conducting plate 3 to heat the water inside by absorbing the heat transferred by the heat-conducting plate 3, converting it into steam. The rear end of the heating pipe 10 is connected to the water tank 9, and the top end of the heating pipe 10 penetrates the outer casing 1 and is connected to a steam pipe 11. The steam pipe 11 is used to heat the water inside the heating pipe 10. The generated steam is delivered to the location where steam is needed, realizing steam output. The bottom of the steam pipe 11 is connected to the water inlet pipe 12, which replenishes the heating pipe 10 with water from the water tank 9, maintaining the water supply during steam generation. A water pump 13 is fixedly connected to the rear side of the outer wall of the outer casing 1 to provide power. The rear end of the water pump 13 is connected to the water delivery pipe 14, which serves as a water delivery channel, connecting the water pump 13 and the water inlet pipe 12 to realize water transmission. The top end of the water delivery pipe 14 is connected to the water inlet pipe 12, ensuring that water can flow smoothly from the water delivery pipe 14 into the water inlet pipe 12 and into the water tank 9. The water tank 9 is equipped with a water replenishment mechanism 2, which is used to ensure that the water in the water tank 9 is sufficient to ensure steam generation. The process will not be interrupted due to lack of water. The bottom of the outer casing 1 is fixedly connected with feet 15 on all four sides to support the entire device and ensure its stable placement. The bottom center of each foot 15 is provided with positioning holes 16. The positioning holes 16 can be used to fix the device to the mounting surface through connectors to prevent displacement of the device during operation. An information board 17 is provided on the front side of the outer wall of the outer casing 1 to display relevant information of the device for the convenience of users to understand and operate the device. Screws 18 are threaded to the four corners of the information board 17. The rear ends of the screws 18 are threaded to the outer casing 1, and the information board 17 is firmly fixed to the outer casing 1 by the screws 18 to ensure the stability of the information board 17.

[0033] Specifically, natural gas is first introduced from an external gas source via natural gas pipeline 5. The pipeline passes through the outer shell 1 and the insulation layer 4 at the bottom of the inner wall, delivering the natural gas to the natural gas nozzle 6. At this time, the igniter 7 generates an electric spark, instantly igniting the natural gas sprayed from the nozzle 6. Simultaneously, outside air is attracted by the combustion negative pressure and pressure difference, entering through the air inlet on the air guide shroud 8 at the top of the nozzle 6, mixing thoroughly with the natural gas, promoting efficient combustion and releasing a large amount of heat energy. The insulation layer 4 effectively reduces heat loss to the bottom. Water in the water tank 9 flows into the heating pipe 10. The heat generated by combustion is conducted to the heating pipe 10 via the heat conduction plate 3, heating the water inside the heating pipe 10. As heat is continuously transferred, the water temperature is maintained. The steam continues to rise until it boils and vaporizes into steam. Since the rear end of the heating tube 10 is connected to the water tank 9, the water in the water tank 9 is continuously replenished to ensure stable steam generation. The generated steam enters the steam pipe 11 through the top of the heating tube 10. The foot 15 supports the entire device to ensure that the device is placed stably. The positioning hole 16 opened in the middle of the bottom of the foot 15 is used to connect it to the ground or the mounting platform with the help of connectors to prevent the device from shifting during operation and to ensure its stability. The information plate 17 is used to display relevant information about the clean steam combustion generator. The information plate 17 is firmly connected to the outer shell 1 by screws 18 threaded at the four corners. This connection method facilitates the installation and removal of the information plate 17.

[0034] Reference Figure 1 , Figure 2 and Figure 5 The water replenishment mechanism 2 includes a fixing ring 201, which provides an installation base for subsequent components. The fixing ring 201 is fixedly connected to the left side of the inner wall of the water tank 9. A hollow tube 202 is fixedly connected to the inner wall of the fixing ring 201, providing a sliding track for the slide rod 203. The slide rod 203 is slidably connected to the inner wall of the hollow tube 202 and moves up and down inside the hollow tube 202. A float 204 is fixedly connected to the top of the slide rod 203. The float 204 can float up and down with the change of water level in the water tank 9. An extension rod 205 is fixedly connected to the rear side of the top of the float 204. The extension rod 205 moves synchronously with the float 204. A waterproof switch 206 is fixedly connected to the rear side of the inner wall of the water tank 9. The waterproof switch 206 is electrically connected to the water pump 13. When the extension rod 205 touches the waterproof switch 206, it can control the start and stop of the water pump 13, thereby realizing the automatic water replenishment function of the water tank 9, ensuring that the water level in the water tank 9 is always maintained within a suitable range, and ensuring stable steam generation.

[0035] Specifically, the fixing ring 201 provides stable support for the hollow tube 202. A sliding rod 203 is slidably connected inside the hollow tube 202. A float 204 is connected to the top of the sliding rod 203. When the water tank 9 is full, the float 204 is at a higher position due to buoyancy. At this time, the extension rod 205 connected to the rear of the top of the float 204 maintains a certain distance from the waterproof switch 206 on the rear side of the inner wall of the water tank 9. The waterproof switch 206 is in the open state, and the water pump 13 electrically connected to it does not work. As the water level in water tank 9 gradually decreases, the float 204 descends along with the water level due to reduced buoyancy, causing the slide bar 203 to slide downwards inside the hollow tube 202. At the same time, the extension rod 205 also descends. When the water level drops to a certain level, the extension rod 205 descends until it touches the waterproof switch 206. The waterproof switch 206 closes, thereby connecting the circuit and sending a start signal to the water pump 13. The water pump 13 starts working and draws water from the water supply pipe 14 into water tank 9, realizing automatic water replenishment.

[0036] Reference Figure 1 , Figure 2 and Figure 4 The top of the outer casing 1 is fixedly connected to the mounting box 19, which provides installation space for the alarm light 20. The inner wall of the mounting box 19 is fixedly connected to the alarm light 20. The alarm light 20 can emit warning signals by emitting light, etc., to remind the operator to deal with the situation in time and ensure the safe operation of the device. The bottom of the water tank 9 is fixedly connected to the support base 21, which serves to support the water tank 9 and ensure that the water tank 9 is placed stably. The front side of the outer wall of the support base 21 is threaded with multiple bolts 22. The support base 21 is threaded to the outer casing 1 through the bolts 22, so that the water tank 9 is firmly connected to the outer casing 1 and the stability of the entire device structure is guaranteed.

[0037] Specifically, the alarm light 20 is fixed in the mounting box 19 on the top of the outer casing 1. When the device malfunctions, the alarm light 20 will light up to warn the user. The support base 21 at the bottom of the water tank 9 is connected to the outer casing 1 by bolts 22. The support base 21 supports the water tank 9, and the bolts 22 ensure a secure connection and guarantee the overall structural stability of the device.

[0038] Reference Figure 1 , Figure 3 and Figure 4A humidity sensor 23 is fixedly connected to the top right side of the inner wall of the outer casing 1, which can monitor the humidity of the steam inside the outer casing 1 in real time. A controller 24 is fixedly connected to the right side of the outer wall of the outer casing 1. The humidity data collected by the humidity sensor 23 can be transmitted to the controller 24 in a timely manner. The controller 24 can adjust the device according to preset parameters to ensure that the steam humidity is maintained within a suitable range. The humidity sensor 23 and the controller 24 are electrically connected. The front ends of multiple screws 18 are provided with cross grooves 25, which facilitates operation with a cross screwdriver. The surfaces of multiple screws 18 are smoothed to improve the smoothness of operation, reduce wear caused by friction, and help prevent rust and corrosion, thus extending the service life of the screws 18.

[0039] Specifically, the humidity sensor 23 monitors the steam humidity inside the housing in real time and transmits the humidity data to the controller 24 in the form of an electrical signal. After receiving the signal, the controller 24 adjusts the operation of the device according to the preset program to ensure that the steam humidity meets the standard. The cross groove 25 is easy to tighten with a Phillips screwdriver, and the smooth surface treatment reduces the tightening resistance and prevents corrosion, ensuring that the information plate 17 is easy to install and disassemble and has a stable connection.

[0040] Working principle: Natural gas is introduced from the outside through the natural gas pipeline 5, passes through the outer shell 1 and the insulation layer 4, and reaches the natural gas nozzle 6. The igniter 7 generates an electric spark to ignite the sprayed natural gas. At the same time, the negative pressure and pressure difference of the outside air caused by combustion enter through the air intake hole of the air guide shroud 8 and mix with the natural gas for combustion. The insulation layer 4 reduces heat loss to the bottom and improves thermal efficiency. Water in the water tank 9 flows into the heating pipe 10 under the action of gravity. The heat generated by combustion is conducted to the heating pipe 10 through the heat conduction plate 3 to heat the water in the pipe. The water absorbs heat and its temperature rises until it boils and vaporizes into steam. Because the rear end of the heating pipe 10 is connected to the water tank 9, the water tank 9 can continuously replenish water to ensure stable steam generation. Finally, the generated steam enters the steam pipe 11 from the top of the heating pipe 10 so as to be transported to the equipment or process that uses the steam.

[0041] Furthermore, when the water tank 9 is full and the water level is high, the float 204 is at a high position due to the buoyancy of the water. At this time, the extension rod 205 connected to the rear of the top of the float 204 is kept at a distance from the waterproof switch 206 on the rear of the inner wall of the water tank 9. The waterproof switch 206 is in the open state, and the water pump 13, which is electrically connected to it, does not work. As the water in the water tank 9 is continuously consumed, the water level gradually drops, and the buoyancy of the float 204 decreases accordingly. It then drops with the water level, thereby driving the slide rod 203 to slide downward in the hollow tube 202. The extension rod 205 also drops synchronously. When the water level drops to a certain level, the extension rod 205 drops down to contact the waterproof switch 206. This contact causes the waterproof switch 206 to close, thereby connecting the circuit. After the circuit is connected, a start signal is sent to the water pump 13, and the water pump 13 starts to operate, drawing water from the water supply pipe 14 into the water tank 9 to realize the automatic water replenishment of the water tank 9, ensuring that the water level in the water tank 9 is maintained within a suitable range, and ensuring the stable operation of the entire system.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
