The multiple sets of mounting crossbars 15 provide an installation base for the boiler shell 16. They are evenly distributed on the hot water storage tank 13, ensuring the stability of the boiler shell 16 installation.

[0026] A boiler shell 16 is provided on multiple sets of mounting crossbars 15. The boiler shell 16 encloses the boiler body 12, which serves to protect the boiler body 12 and maintain internal heat, reduce heat loss to the outside, and improve energy utilization efficiency. The boiler body 12 is located inside the boiler shell 16 and is the core component for realizing fuel combustion and generating heat energy. Multiple sets of retaining frames 17 are provided inside the boiler shell 16. The multiple sets of retaining frames 17 provide positioning and support for the boiler body 12. The boiler body 12 is secured on the multiple sets of retaining frames 17, so that the boiler body 12 can be stably installed inside the boiler shell 16. And through the fixation of the retaining frames 17, the displacement of the boiler body 12 due to vibration and other factors can be avoided. One set of frame 17 forms a flue gas chamber with the boiler shell 16. This flue gas chamber is used to collect and guide the flue gas generated by the combustion of the boiler body 12. Multiple sets of frame 17 are connected by multiple sets of flue gas pipes 18. These flue gas pipes 18 form the flow path of flue gas inside the boiler. Multiple sets of flue gas pipes 18 are arranged in a ring above the boiler body 12. This ring arrangement allows the flue gas to surround the boiler body 12 more evenly, so that the heat can be transferred to the surrounding medium more fully and the heat transfer efficiency can be improved.

[0027] A flue gas sleeve 19 is fitted at one end of the boiler body 12. The flue gas sleeve 19 further seals the connection between the boiler body 12 and the flue gas related components to prevent flue gas leakage. On the other hand, the flue gas sleeve 19 and one of the sets of retaining frames 17 form a flue gas chamber again, which enhances the collection and guidance effect of flue gas. The baffle 14 is located on one side of the boiler shell 16. A fan 21 and an air inlet pipe are provided on one side of the baffle 14. The fan 21 is used to deliver air into the boiler body 12 to meet the oxygen requirements for fuel combustion. By adjusting the operation of the fan 21, the intensity of combustion can be controlled. One end of the air inlet pipe passes through the baffle 14, the boiler shell 16 and the flue gas sleeve 19 in sequence and connects to one end of the boiler body 12. It provides a channel for the fan 21 to deliver air to the boiler body 12, ensuring that the air can accurately and smoothly enter the boiler body 12 to participate in the combustion process. A controller 22 is provided on one side of the housing box 11. The controller 22 serves as the control core of the entire boiler system. The controller 22 can be an SML-800A controller.

A flue gas vent 23 and a pressure relief vent 24 are provided on one side of the housing frame 11. The flue gas vent 23 provides an outlet for the flue gas generated by boiler combustion to be discharged from the boiler. The flue gas vent ring 19 is connected to the flue gas vent 23 through a pipe to ensure that the flue gas can be smoothly discharged from the boiler to the external environment. The pressure relief vent 24 is used to release excessive pressure that may be generated inside the boiler due to pressure changes, ensuring the safety of boiler operation. A water inlet pipe 25 is installed on the housing frame 11. One end of the water inlet pipe 25 is connected to the pressure relief vent 24, and the other end is connected to the boiler shell 16 to form the first water chamber. The water inlet pipe 25 is located above the boiler shell 16, so that cold water can enter through the water inlet pipe. The water inlet pipe 25 enters the first water chamber. Simultaneously, the steam or hot water discharged from the pressure relief hole 24 carries heat to preheat the cold water in the inlet pipe 25, improving energy efficiency. A first drain pipe 26 is provided on one side of the boiler shell 16, and a first drain valve 27 is fitted onto the first drain pipe 26. One end of the first drain pipe 26 is connected to the boiler shell 16, and the other end is connected to the hot water storage tank 13. By controlling the opening and closing of the first drain valve 27, the heated hot water in the boiler shell 16 can be transported to the hot water storage tank 13 for storage. A second drain pipe 28 is provided on the receiving frame box 11, and a second drain valve 29 is fitted onto the second drain pipe 28. One end of the second drain pipe 28 passes through the receiving frame box 11, and the other end is connected to the hot water storage tank 13. It serves as a backup or auxiliary drain channel and can work in conjunction with the first drain pipe 26 as needed to further ensure that hot water can flow smoothly into the hot water storage tank 13.

[0028] A sealing ring 31 is provided on one side of the flue gas sleeve 19. The sealing ring 31 enhances the sealing performance between the flue gas sleeve 19 and surrounding components, effectively preventing flue gas leakage from the connection point and ensuring that the flue gas can flow along the predetermined path, thereby improving the safety and thermal efficiency of boiler operation. Dividing plates 32 are installed on multiple sets of flue gas pipes 18. Multiple sets of perforations are provided on the dividing plates 32, which subdivide the space within the flue gas pipes 18. The multiple perforations allow the flue gas to be evenly dispersed when passing through the dividing plates 32, further optimizing the flow path and distribution of the flue gas within the pipes and enhancing the heat exchange effect. Multiple sets of buffer plates 33 are also provided on the dividing plates 32. The buffer plates 33 can buffer the high-speed flowing flue gas, reducing the impact of the flue gas on the inner wall of the pipes, extending the service life of the flue gas pipes 18, and also helping to stabilize the flow state of the flue gas, making the heat exchange process more stable. A feed hole is provided on one side of the receiving frame box 11, and a feed funnel 34 is provided on the feed hole. The feed hopper 34 makes it convenient for users to add fuel into the boiler body 12. Its wide opening facilitates fuel delivery and guides the fuel smoothly into the feed hole, ensuring the convenience and efficiency of the fuel addition process.

[0029] like Figures 2 to 5 As shown, when using this device, the user first places the housing frame 11 in a suitable installation position. The housing frame 11 supports the entire boiler, ensuring its stable placement. Next, the hot water storage tank 13 on the housing frame 11 comes into play, storing hot water for use. The partitions 14 on the hot water storage tank 13 divide the space, ensuring the hot water is stored stably. Multiple sets of mounting crossbars 15 provide stable support for the boiler shell 16. The boiler shell 16 encloses the boiler body 12, protecting the body and reducing heat loss.

[0030] The boiler body 12 is the core of heat generation. Multiple sets of retaining frames 17 inside the boiler shell 16 position and support the boiler body 12 to prevent displacement. One set of retaining frames 17 and the boiler shell 16 form a flue gas exhaust chamber to guide the flue gas. The flue gas pipes 18 between the multiple sets of retaining frames 17 are arranged in a ring above the boiler body 12 to help the flue gas evenly transfer heat. The flue gas exhaust ring 19 at one end of the boiler body 12 seals the connection to prevent flue gas leakage and also enhances flue gas collection with the retaining frames 17. The fan 21 located at the partition 14 on one side of the boiler shell 16 supplies oxygen to the boiler body 12 for combustion through the air inlet pipe. Adjusting the fan can control combustion. The controller 22 on one side of the housing box 11 is connected to the fan 21, allowing the user to adjust the fan, optimize combustion conditions, and improve thermal efficiency.

[0031] The flue gas vent 23 on the receiving frame 11 is used to discharge flue gas, and the pressure relief vent 24 ensures safety. The water inlet pipe 25, connected to the pressure relief vent 24, forms the first water chamber with the boiler shell 16, allowing cold water to enter and be preheated. The first drain pipe 26 of the boiler shell 16 connects to the hot water storage tank 13, and the first drain valve 27 controls the delivery of hot water to the storage tank. The second drain pipe 28 on the receiving frame 11, equipped with a second drain valve 29, serves as a backup channel to facilitate the entry of hot water into the tank. The sealing ring 31 of the flue gas sleeve 19 prevents flue gas leakage. The dividing plate 32 of the flue gas duct 18 has leakage holes, dividing the space to allow for uniform flue gas flow and enhance heat exchange. The buffer plate 33 on the dividing plate 32 buffers the flue gas and extends the service life of the duct. The feed hopper 34 on one side of the receiving frame 11 facilitates fuel addition. Its large opening facilitates fuel delivery and guides fuel into the feed hole, making fuel addition convenient and efficient. This design improves boiler performance in many ways and meets usage requirements.

[0032] The specific usage and function of this embodiment are as follows:

[0033] When using this device, first, the housing box 11 is placed in a suitable position, providing stable support for the boiler. The hot water storage tank 13 on it is used to store heated hot water. The partition 14 optimizes the storage and flow of hot water. The mounting strip 15 provides stable support for the boiler shell 16. The boiler body 12 is responsible for combustion and heat generation inside the shell.
