[0026] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0027] Example:

[0028] like Figures 1 to 9As shown, this utility model provides a convenient and clean gas-fired heating and hot water boiler, including a base 11 and a shell 12. The shell 12 is U-shaped and is placed on the base 11 in an inverted state. At both ends of the shell 12, a front baffle 13 and a rear baffle 14 are respectively positioned. The front baffle 13 is connected to the shell 12 by two sets of hinges 15, allowing it to rotate. The base 11 has a circulation component and a slot 16, in which a water pump 17 is held. Inside the shell 12, there is a partition 18 with a through slot through which a support 19 passes. The support 19 has an arc-shaped groove in which the combustion component is held. Below the support 19, a gas nozzle 21 and a fan 22 are located. The fan 22 is installed on one side of the gas nozzle 21, blowing air directly onto the gas nozzle 21. This arrangement allows the fan 22 to supply air to the gas nozzle 21, assisting in better combustion of the gas.

[0029] like Figures 2 to 4 , Figures 6 to 8 As shown, the gas assembly is a key component of the gas-fired heating and hot water boiler, comprising an installation cylinder 23 and a combustion chamber 24. A mounting plate 25 is mounted on the partition 18. One end of the installation cylinder 23 is connected to the mounting plate 25, while the other end is detachably connected to one end of the combustion chamber 24. The combustion chamber 24 is placed in an arc-shaped support groove. A rotating hole 26 is provided on one side of the outer casing 12. A chuck is provided at one end of the combustion chamber 24, passing through the rotating hole 26 and locking onto the outside of the outer casing 12. Both the bottom of the combustion chamber 24 and the support base 19 have square grooves, through which the combustion chamber 24 connects to the gas nozzle 21. This connection method allows gas to smoothly enter the combustion chamber 24 from the gas nozzle 21 for combustion, providing energy for heating. Furthermore, this installation method of the combustion chamber 24 facilitates its removal for cleaning or maintenance, improving the convenience of equipment maintenance.

[0030] Inside the mounting cylinder 23, there are two sets of locking blocks 27. At one end of the combustion chamber 24, there are two sets of annular grooves 28. The locking blocks 27 fit perfectly into the annular grooves 28, thus connecting the mounting cylinder 23 and the combustion chamber 24. One side of the rotating hole 26 has a positioning port 29, and one side of the chuck has a positioning block 37. The central axis of the positioning block 37 forms an angle α with the central axis of the positioning port 29, which is between 60° and 90°. The other side of the chuck also has a pull ring. With this structure, when it is necessary to remove or install the combustion chamber 24, the pull ring can be used to rotate the chuck, and the positioning block 37, in conjunction with the positioning port 29, can install the combustion chamber 24 into place. This also facilitates quick disassembly during cleaning, ensuring ease of operation.

[0031] In addition to the aforementioned components, the gas assembly also includes a heating pipe 31 and a flue pipe 32. The heating pipe 31 passes through the combustion chamber 24 and the mounting cylinder 23. The flue pipe 32 also has an arc-shaped support groove located above the combustion chamber 24. The heating pipe 31 absorbs the heat generated by the combustion of gas in the combustion chamber 24 to heat the water passing through it. Both ends of the heating pipe 31 are connected to the water pump 17 or the water tank 33, respectively. The flue pipe 32 is used to exhaust the combustion gases. The arc-shaped support groove below it provides support, making the entire gas assembly more stable during operation and facilitating the positioning of the flue pipe 32 for easy exhaust gas discharge.

[0032] like Figures 2 to 3 , Figure 5 As shown, the circulation assembly consists of a water tank 33 and a snap-fit ​​34. The water tank 33 is snapped into the snap-fit ​​34, and the two can be detached and connected. A groove is formed at the bottom of the water tank 33, and a slider is provided on the base 11, allowing the groove and slider to slide together. This connection allows the water tank 33 to move relative to the base 11, making it easier to remove the water tank 33 when needed, such as during water addition or cleaning. This makes operations more flexible and convenient. Simultaneously, the snap-fit ​​34 provides a certain degree of fixation for the water tank 33, ensuring its stability during equipment operation.

[0033] The buckle 34 is made of aluminum alloy and has four sets of clamping blocks at one end, which are secured to one side of the water tank 33. A pull handle is located on one side of the water tank 33, with a drain outlet below the handle. The aluminum alloy buckle 34 has a certain strength and corrosion resistance, and the four sets of clamping blocks can effectively hold the water tank 33 in place. The pull handle allows users to easily pull and push the water tank 33 in, while the drain outlet facilitates the drainage of water from the tank 33, making it very convenient for cleaning the water tank 33 and for draining water during use.

[0034] like Figures 2 to 4 , Figure 8 As shown, an air duct 35 is provided on the rear baffle 14, and the fan 22 is mounted at one end of the air duct 35; a protective plate 36 is provided between the baffle 18 and the outer casing 12, and the protective plate 36 is located on one side of the combustion chamber 24. The air duct 35 provides an airflow channel for the fan 22, allowing the fan 22 to better supply air for gas combustion. The protective plate 36 provides a certain degree of protection for the combustion chamber 24, preventing the combustion chamber 24 from damaging surrounding components during operation. It also provides a certain degree of insulation against the heat generated by the combustion chamber 24, improving the overall safety and stability of the equipment. It also facilitates the cleaning of other components to a certain extent, preventing them from being affected by the combustion chamber 24.

[0035] The specific usage and function of this embodiment are as follows:

[0036] When using this gas-fired heating and hot water boiler, open the front baffle 13, which is rotatably connected to the outer casing 12 via two sets of hinges 15 for easy operation. Start the fan 22, which is located on one side of the gas nozzle 21 with its air outlet aligned with the gas nozzle 21, blowing air towards the gas nozzle 21 to improve gas combustion. Gas is ejected from the gas nozzle 21 and enters the combustion chamber 24 through the square groove at the bottom of the combustion chamber 24 for combustion.

[0037] The heat generated by combustion is transferred through heating pipe 31 to heat the internal medium. The generated flue gas is discharged through flue pipe 32. The water tank 33 is fixed by buckle 34 and can slide with the slider of the base 11 through the slide groove, so that the water tank 33 can be easily removed for cleaning or maintenance.

[0038] Combustion chamber 24 is connected to mounting cylinder 23 via annular groove 28 on chuck. When combustion chamber 24 needs to be cleaned, the pull ring on chuck drives combustion chamber 24 to rotate, causing locking block 27 to rotate out of annular groove 28, releasing the lock of combustion chamber 24. Then, combustion chamber 24 is pulled out of rotation hole 26 and removed. After cleaning, first align positioning block 37 on chuck with positioning port 29 on rotation hole 26, push in combustion chamber 24, and after locking block 27 into annular groove 28, rotate chuck to complete installation.

[0039] The entire device can realize gas combustion heating and water circulation functions, providing users with heating and hot water. At the same time, some components are detachable, making daily cleaning and maintenance convenient.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
