Description

Technical Field

[0001] This utility model belongs to the field of automotive engineering technology, and specifically relates to a water-heated fuel liquid heater. Background Technology

[0002] In the field of automotive heating and engine preheating, water-based fuel liquid heaters are widely used as independent heat source devices. They generate heat through fuel combustion, using water or antifreeze as a medium to circulate and transfer heat, achieving cabin heating and engine preheating at low temperatures. However, existing water-based fuel liquid heaters are prone to minor leaks at pipe interfaces, combustion chamber and heat exchanger connections due to vibration, temperature changes, and aging seals during long-term use. Since these devices are often installed in enclosed, confined spaces such as the engine compartment or chassis of a car, and the initial leakage flow is extremely small, the leaked liquid drips directly into hidden parts of the vehicle body, making it difficult to detect visually. Failure to address the initial leak promptly leads to loss of the circulating medium, reducing heat exchange efficiency, decreasing heating performance, and affecting heating effect and engine preheating speed. Furthermore, continuous leakage exacerbates seal wear and can even trigger a chain reaction of faults such as pipe corrosion and short circuits in electrical components. In severe cases, it can lead to engine overheating and damage to the heater's core components, significantly increasing maintenance costs and safety hazards. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide a novel water-heating fuel liquid heater that solves the problem of difficulty in detecting leaks in water-heating fuel liquid heaters.

[0004] To achieve the above objectives, a water-heated fuel liquid heater includes a fuel-heated water heater body, on which a rear mounting bracket and a front mounting bracket are installed. The fuel-heated water heater body is fixed inside a car via the rear mounting bracket and the front mounting bracket. A detection assembly includes a liquid guide plate, an arc-shaped plate, and a collection box. The arc-shaped plate has a liquid guide groove and is connected to the liquid guide plate. The collection box is connected to the liquid guide plate. A float plate slides on the inner wall of the collection box and is capable of floating on the oil. A vertical rod is installed on the float plate, and a detection rod is installed on the top of the vertical rod.

[0005] Preferably, the detection component is supported between the rear mounting bracket and the front mounting bracket, and the detection component is connected to the rear mounting bracket and the front mounting bracket via a mounting rod.

[0006] Preferably, the liquid guide plate is connected to the arc-shaped plate via a riser, and the arc-shaped plate is connected to the fuel-fired water heater body via a connecting block.

[0007] Preferably, a fixing frame is installed on the inner wall of the liquid guide plate, and a support rod connected to the bottom of the riser is installed on the inner wall of the fixing frame.

[0008] Preferably, the collection box and the liquid guide plate are connected by a drain pipe, and the upright extends through the top of the collection box.

[0009] This utility model has the following beneficial effects:

[0010] 1. By setting up detection components and a float, slight leaks in the equipment can be quickly detected. The leaked liquid is collected by an arc-shaped plate and guided to a collection tank by a liquid guide plate. As the liquid level rises, the float causes the upright and detection rod to rise synchronously. The leakage situation can be judged intuitively by the change in the height of the detection rod. This solves the problem that it is difficult to detect the initial leakage of traditional equipment and avoids the reduction in heating efficiency or damage to components caused by the expansion of leakage.

Detailed Implementation

[0016] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0017] Example 1:

[0018] like Figure 1As shown in Figure 4, this utility model provides the following technical solution: it includes a fuel water heater body 1, on which a rear mounting bracket 11 and a front mounting bracket 12 are installed. The fuel water heater body 1 is fixed in the car through the rear mounting bracket 11 and the front mounting bracket 12. The detection component 2 includes a liquid guide plate 21, an arc plate 22 and a collection box 23. A liquid guide groove 211 is opened on the arc plate 22 and is connected to the liquid guide plate 21. The collection box 23 is connected to the liquid guide plate 21. A float plate 3 slides on the inner wall of the collection box 23 and can float on the oil. A vertical rod 31 is installed on the float plate 3 and a detection rod 32 is installed on the top of the vertical rod 31.

[0019] In this implementation scheme: The fuel-fired water heater body 1 generates heat energy by burning fuel such as diesel or gasoline, and uses water or antifreeze as the heat transfer medium. The fuel-fired water heater body 1 is connected to pre-installed connection equipment in the vehicle via a rear mounting bracket 11 and a front mounting bracket 12 mounted at its bottom. A detection component 2 installed between the rear mounting bracket 11 and the front mounting bracket 12 can collect leaks when the fuel-fired water heater body 1 is running. The leaked liquid is supported below the fuel-fired water heater body 1 by a guide plate 21. An arc-shaped plate 22 is located at the connection points of various components of the fuel-fired water heater body 1. When the seal at the connection point is compromised, the leaked liquid can be guided to the guide plate 21 by the arc-shaped plate 22. The guide plate 21 then concentrates the leaked liquid into a collection tank 23. Once the liquid reaches the collection tank 23, the leaked oil or other liquids can affect the float plate. 3. Buoyancy is generated, allowing the float plate 3 to float on the liquid surface. When the float plate 3 moves up and down, the pre-installed limiting rod in the central box 23 can limit the displacement of the float plate 3, allowing the float plate 3 to move vertically. This allows the upright rod 31 to slide on the central box 23, supporting the height of the detection rod 32. At this time, the change in the height of the detection rod 32 can be used to determine whether leakage has occurred. This avoids the situation where, when the equipment has a slight leakage, the amount of liquid leaked is small and will directly flow downwards, making it difficult to accurately determine the leakage. If the leakage is not dealt with in time, it will affect the overall heating effect of the equipment. Whether it is preheating the engine or heating the carriage, the expected temperature will not be reached, and it will have an adverse effect on the overall quality of the vehicle body. Therefore, the device can directly determine the leakage by observing the height of the detection rod 32, the time of the front and rear inspections, and the amount of change in the height of the detection rod 32, thereby ensuring the safe use of the equipment.

[0020] The detection component 2 is supported between the rear mounting bracket 11 and the front mounting bracket 12. The detection component 2 is connected to the rear mounting bracket 11 and the front mounting bracket 12 by the mounting rod 27. The detection component 2 is supported between the rear mounting bracket 11 and the front mounting bracket 12, and the arc plate 22 and the detection component 2 are located below the center of the fuel water heater body 1. This allows the leakage generated by the fuel water heater body 1 to be concentrated by the arc plate 22, so that the leakage can be guided into the collection box 23. The mounting rod 27 is used to support the liquid guiding plate 21, so that the liquid guiding plate 21 is stably supported between the rear mounting bracket 11 and the front mounting bracket 12.

[0021] The liquid guide plate 21 and the arc plate 22 are connected by a riser 26, and the arc plate 22 is connected to the fuel water heater body 1 by a connecting block 221. The liquid guide plate 21 and the arc plate 22 are connected by a riser 26, which connects the arc plate 22 and the liquid guide plate 21, so that the riser 26 can discharge the liquid in the arc plate 22 into the liquid guide plate 21. The arc plate 22 is supported and connected to the fuel water heater body 1 by the connecting block 221.

[0022] A fixing frame 25 is installed on the inner wall of the liquid guide plate 21, and a support rod 251 connected to the bottom of the riser 26 is installed on the inner wall of the fixing frame 25. The fixing frame 25 installed on the inner wall of the liquid guide plate 21 can fix the bottom of the riser 26 through the support rod 251, so that the riser 26 is aligned with the liquid guide tank 211, and the liquid is discharged into the liquid guide tank 211.

[0023] The central tank 23 is connected to the liquid guide plate 21 by a drain pipe 24, and the upright 31 passes through the top of the central tank 23. The central tank 23 and the liquid guide plate 21 are connected by a drain pipe 24, so that the liquid can flow into the central tank 23 to judge the leakage of the equipment. The upright 31 passes through the top of the central tank 23, so that the upright 31 can slide synchronously with the float 3 to support the height of the detection rod 32.

[0024] The working principle of this technical solution is as follows: The fuel water heater body 1 is connected and fixed to the preset installation position in the car through the rear mounting bracket 11 and the front mounting bracket 12 at the bottom. The detection component 2 is supported between the rear mounting bracket 11 and the front mounting bracket 12 by the mounting rod 27, ensuring that the arc plate 22 is directly opposite the various pipe interfaces and seals of the fuel water heater body 1. The connecting block 221 is connected and fixed to the fuel water heater body 1 to ensure that the leaking liquid can flow smoothly into the arc plate 22. When the fuel water heater body 1 is working, if all components are well sealed and there is no leakage, there is no liquid in the liquid guide plate 21 and the collection box 23, the float plate 3 is at the bottom of the collection box 23, and the detection rod 32 is at the lowest position, it indicates that the equipment is operating normally. When the equipment has a slight leakage, such as aging of the seals or loosening of the pipes, the leakage will drip. The liquid flows into the arc-shaped plate 22, is guided through the riser 26 to the guide plate 21, and then flows into the collection tank 23 through the drain pipe 24. As the liquid level in the collection tank 23 rises, the float 3 slides upward along the inner wall of the collection tank 23 under the action of buoyancy, driving the riser 31 to rise synchronously. The detection rod 32 rises accordingly. Users can judge the occurrence and amount of leakage by observing the height change of the detection rod 32 and comparing it with the initial position. The greater the height change, the greater the leakage. After the detection rod 32 is found to have risen, stop the operation of the fuel water heater body 1, check the connection part of the fuel water heater body 1 corresponding to the arc-shaped plate 22, and find the leak point. If necessary, replace the seals and tighten the pipeline. After the treatment is completed, empty the liquid accumulated in the collection tank 23 of the guide plate 21, reset the float 3, and return the detection rod 32 to the initial position. The equipment can be put back into use.
