The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0021] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The utility model provides a fuel liquid heating device, such as Figure 1-5As shown, the fuel liquid heating device comprises: a fuel liquid heater body 1, the fuel liquid heater body 1 comprises a heat exchanger shell 2, a cooling shell 3 and a heat exchange shell 4, the heat exchanger shell 2 is provided with a flange, the cooling shell 3 and the heat exchange shell 4 are provided with the same burner 10, the burner 10 is used to heat the fuel liquid; two threaded barrels 13, the two threaded barrels 13 are symmetrically threadedly assembled on the cooling shell 3, and are used to connect and fix two first bolts 11 of the cooling shell 3, the two first bolts 11 are both provided on the heat exchange shell 4, and the two first bolts 11 are provided on the heat exchange shell 4. One end of a bolt 11 is threadedly connected with the corresponding threaded barrel 13; a sealing ring 12 is used to seal the connection between the cooling shell 3 and the heat exchange shell 4, and the sealing ring 12 is arranged on the top of the heat exchange shell 4; two second bolts 14 are symmetrically arranged on the heat exchanger shell 2, and one end of the two second bolts 14 is threadedly connected with the corresponding threaded barrel 13; a protective mechanism is used to protect the heat exchanger shell 2, the cooling shell 3 and the heat exchange shell 4, and the protective mechanism is arranged on the heat exchanger shell 2 and the heat exchange shell 4.

[0023] It should be noted that, at present, the structure of the fuel liquid heating device is mainly composed of a heat exchanger shell, a cooling shell, a heat exchange shell and a burner; the heat exchanger shell: this is the outer structure of the entire heating device, which is used to protect the internal heat exchange components and burners, and also plays a certain role in heat insulation; the cooling shell is usually located outside or near the heat exchange shell, which is used to reduce the heat generated during the heat exchange process and ensure that the device operates within a safe temperature range; this is the core part of the heating device, which includes a heat exchanger, which is responsible for transferring the heat generated by the burner to the liquid to be heated; the burner is the heat generating part, which provides heat energy by burning fuel. Due to the influence of fuel quality, impurities will accumulate inside the burner and need to be cleaned regularly; the various components in the device are usually fastened and connected by two or more long first bolts to ensure that they will not loosen due to vibration or temperature changes during operation; due to the quality of fuel, some impurities such as carbon deposits, sludge, etc. will inevitably accumulate inside the burner; these impurities will affect the combustion efficiency and even cause burner failure, so they need to be disassembled and cleaned regularly; the cooling shell and the heat exchange shell and other components are connected and fixed by a common first bolt. This design is relatively convenient for assembly and disassembly, but it also brings some problems. When the cooling shell and the heat exchange shell need to be disassembled for cleaning, the antifreeze in the internal liquid storage chamber will often flow out because the sealing structure between them is broken. This not only causes a waste of resources, but also may pollute the environment. Antifreeze is an important component of the heating device. Its loss means that it needs to be refilled or replaced, which undoubtedly increases the maintenance cost. At the same time, frequent replacement of antifreeze may also affect the service life and performance of the device. Therefore, how to solve the above problems requires the development of a new type of fuel liquid heating device.

[0024] In this embodiment, when it is necessary to clean the impurities inside the burner 10, it is necessary to disassemble the heat exchanger shell 2 and the cooling shell 3 (first unscrew the second bolt 14, the second bolt 14 is separated from the threaded tube 13, and the heat exchanger shell 2 loses the limit and can be separated from the cooling shell 3); in this process, since the sealing structure between the cooling shell 3 and the heat exchange shell 3 is not broken, the antifreeze will not flow out, which solves the problem of easy loss of antifreeze when the burner 10 is disassembled and cleaned in the existing fuel liquid heating device, thereby causing waste of resources.

[0025] In a further preferred embodiment of the utility model, the protective mechanism includes: a second threaded column 15 fixed on the heat exchange shell 4; a first protective shell 17 sleeved on the second threaded column 15, the first protective shell 17 is fitted with the heat exchange shell 4; a second protective shell 18 snapped on the heat exchanger outer shell 2; a nut 16 threadedly sleeved on the second threaded column 15, and the nut 16 is used to limit the first protective shell 17.

[0026] In this embodiment, the second threaded column 15 is fixed on the heat exchange shell 4 as a basis for connecting and fixing other components; the first protective shell 17 is sleeved on the second threaded column 15 and fits tightly with the heat exchange shell 4. Such a design enables the first protective shell 17 to tightly cover and protect part or all of the surface of the heat exchange shell 4 to prevent it from being directly damaged by the external environment, such as impact, scratching, corrosion, etc.; the second protective shell 18 is snapped on the heat exchanger shell 2. Similar to the first protective shell 17, the second protective shell 18 also plays a role in protecting the heat exchanger shell 2, increasing the durability and safety of the entire device; the nut 16 is threadedly sleeved on the second threaded column 15 to limit the first protective shell 17. When the first protective shell 17 is sleeved on the second threaded column 15, by rotating the nut 16, it can be moved downward and tightly pressed against the first protective shell 17, thereby ensuring that the first protective shell 17 is stably fixed on the heat exchange shell 4. This design not only makes the installation and disassembly of the first protective shell 17 simple and convenient, but also provides a reliable fixing force to ensure the protective effect; through the design of the first protective shell 17 and the second protective shell 18, the heat exchange shell 4 and the heat exchanger shell 2 are effectively protected, reducing the risk of damage to them caused by the external environment and improving the safety of the entire device; the disassembly and installation process of the first protective shell 17 and the second protective shell 18 is simple and convenient, so that maintenance and cleaning can be easily carried out when necessary, thereby improving the maintenance convenience of the device.

[0027] In a further preferred embodiment of the present invention, a heat exchanger is arranged inside the heat exchanger housing 2 , and an oil pipe joint 8 and an air inlet 9 are also arranged on the heat exchanger housing 2 .

[0028] In this embodiment, the heat exchanger is arranged inside the heat exchanger housing 2 as the main component of heat exchange; its main function is to receive the heat generated by the burner 10 and effectively transfer the heat to the fuel liquid flowing through, so as to achieve the heating of the fuel; the oil pipe joint 8 is installed on the heat exchanger housing 2 for connecting the external fuel pipeline. Through this joint, the fuel liquid to be heated can flow into the heat exchanger, exchange heat with the heat exchanger, and be heated to the required temperature; the air inlet 9 is also arranged on the heat exchanger housing 2 for providing the required air to the burner 10. Air is one of the important elements in the combustion process, and generates high-temperature heat energy by mixing and burning with the fuel.

[0029] In a further preferred embodiment of the utility model, the cooling shell 3 is provided with an air outlet 5 , a water inlet pipe 6 and a water outlet pipe 7 , and the sealing ring 12 is provided with a through hole, and the through hole is adapted to the first bolt 11 .

[0030] In this embodiment, the air outlet 5 is located at an appropriate position of the cooling shell 3, and is used to discharge the exhaust gas generated during the combustion process. By effectively discharging the exhaust gas, the environment inside the heating device can be kept clean and harmful gases can be prevented from damaging the equipment; the water inlet pipe 6 is used to introduce cooling water or other coolants into the cooling shell 3. Through the circulation of the coolant, the temperature of the cooling shell 3 and its surrounding environment can be effectively reduced, ensuring that the heating device operates within a safe temperature range; the water outlet pipe 7 is responsible for discharging the heated coolant from the cooling shell 3. By reasonably designing the position and connection method of the water outlet pipe, it can be ensured that the coolant can flow smoothly and take away excess heat.

[0031] In a further preferred embodiment of the present invention, threaded holes are symmetrically provided on the cooling shell 3 , and the threaded holes are matched with the corresponding threaded tubes 13 .

[0032] In this embodiment, the threaded holes are designed to symmetrically open threaded holes on the cooling shell 3. These threaded holes are designed to match the threads on the outer surface of the threaded barrel 13 to achieve stable connection and fixation; the size and pitch of the threaded holes match the external threads of the threaded barrel 13, so that the threaded barrel 13 can be smoothly screwed into the threaded holes; when the threaded barrel 13 is screwed into the threaded holes, the cooling shell 3 and other components (such as the heat exchanger shell 2) can be firmly connected through the tight fit of the threads.

[0033] In a further preferred embodiment of the present invention, arc-shaped notches are provided on the ends of the first protective shell 17 and the second protective shell 18 that contact each other, and the arc-shaped notches are adapted to the water inlet pipe 6 and the water outlet pipe 7 .

[0034] In this embodiment, the arc-shaped notch design provided on the first protective shell 17 and the second protective shell 18 not only ensures the integrity and safety of the heat exchanger housing 2, but also improves the convenience and aesthetics of installation; the first protective shell 17 and the second protective shell 18 are each provided with an arc-shaped notch on the end in contact with each other. The shape and size of this notch are carefully designed to ensure that they can fully adapt to the outer contours of the water inlet pipe 6 and the water outlet pipe 7; the design of the arc-shaped notch ensures that the first protective shell 17 and the second protective shell 18 will not block or interfere with the normal use of the water inlet pipe 6 and the water outlet pipe 7 when they are installed on the heat exchanger housing 2. This adaptability ensures that the coolant can smoothly flow into the cooling shell 3 through the water inlet pipe 6 and flow out through the water outlet pipe 7, thereby achieving an effective cooling effect.

[0035] In a further preferred embodiment of the present invention, a mounting hole is provided on the first protective shell 17 , and the corresponding mounting hole is adapted to the second threaded column 15 .

[0036] In this embodiment, mounting holes are provided on the first protective shell 17. The positions and sizes of these mounting holes are designed according to the positions and sizes of the second threaded column 15 to ensure that they can be accurately aligned and adapted; the size of the mounting holes is slightly larger than the outer diameter of the second threaded column 15 to allow the first protective shell 17 to be smoothly sleeved on the second threaded column 15; when the first protective shell 17 is sleeved on the second threaded column 15, the mounting holes and the second threaded column 15 are tightly matched to ensure that the first protective shell 17 can be stably fixed on the heat exchange shell 4; through the adaptation of the mounting holes and the second threaded column 15, the first protective shell 17 can be tightly fitted on the heat exchange shell 4 to provide effective protection; this adaptability also makes the installation and removal process of the first protective shell 17 simple and convenient, and improves the convenience of maintenance.

[0037] In summary, the fuel liquid heating device provided by the technical solution adopts a unique design. During the process of disassembling the heat exchanger shell 2 and the cooling shell 3, the sealing structure between the cooling shell 3 and the heat exchange shell 4 is not broken; this design cleverly avoids the problem of antifreeze outflow when cleaning the burner 10, thereby solving the problem of easy loss of antifreeze and waste of resources during the disassembly and cleaning process of the existing fuel liquid heating device. This design not only improves the maintenance efficiency of the equipment and reduces the maintenance cost, but also reduces the negative impact on the environment.

[0038] Compared with the related art, through the ingenious design of the first bolt 11, the sealing ring 12, the threaded barrel 13 and the second bolt 14, there is no need to destroy the sealing structure when cleaning impurities inside the burner 10, thereby avoiding the loss of antifreeze and reducing resource waste and environmental pollution; by setting up a protective mechanism, additional physical protection is provided for the heat exchanger shell 2, the cooling shell 3, and the heat exchange shell 4 to resist external impact and corrosion, thereby extending the service life of the device.
