Description

Technical Field

[0001] This utility model relates to the field of heating tube technology, and in particular to a spiral heating tube structure for a vehicle-mounted instant hot water dispenser. Background Technology

[0002] In-vehicle instant hot water dispensers are installed in vehicles such as buses and RVs. They use instant heating technology to heat water instantly. Their main function is to provide passengers and drivers with hot water for brewing drinks and cooking food during long journeys, meet the special needs of infant formula preparation and emergency wound cleaning, improve service quality in commercial vehicles, and assist with washing and cooking in RV life. The spiral heating element in the in-vehicle instant hot water dispenser is the core heating element. Its spiral structure increases the heating area of ​​the water flow, achieving rapid heating to meet the demand for hot drinking water.

[0003] However, in the current technology, in the vehicle environment, the spiral heating tube will generate alternating mechanical loads due to the multidimensional vibrations of the vehicle during driving, such as road bumps and engine vibrations. The bending parts will cause stress concentration due to the sudden change in curvature, and the vibration frequency is easy to couple with the natural frequency of the structure to cause resonance, which will further amplify the stress amplitude. At the same time, the temperature change during heating will add additional thermal stress, which will aggravate the fatigue damage of the metal materials. This will make the bending parts of the spiral tube a high-incidence area for material fatigue and insulation layer damage. Ultimately, it may cause safety hazards such as equipment leakage, heating failure, or even electric shock, significantly shortening the service life of the equipment and threatening the safety of the vehicle environment. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a spiral heating tube structure for a vehicle-mounted instant hot water dispenser.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a spiral heating tube structure for a vehicle-mounted instant hot water dispenser, comprising a spiral heating tube body, a main body buffer mechanism installed inside the spiral heating tube body, connecting hoses fixedly connected to both ends of the spiral heating tube body, the main body buffer mechanism comprising a base, a buffer rubber pad fixedly connected to the upper part of the base, a fixing plate fixedly connected to the upper part of the buffer rubber pad, a fixing rod fixedly connected to the upper part of the fixing plate, multiple fixing blocks fixedly connected to the surface of the fixing rod, an arc-shaped shock-absorbing plate fixedly connected to the side of the fixing block, a clamping block fixedly connected to the end of the arc-shaped shock-absorbing plate, the clamping block clamping and fixing the spiral heating tube body, and an end buffer mechanism fixedly connected to the end of the spiral heating tube body.

[0006] Preferably, a rubber vibration isolation pad is fixedly connected inside the clamping block, and the rubber vibration isolation pad is in close contact with the surface of the spiral heating tube body.

[0007] Preferably, the end buffer mechanism includes a second base, a slide rail fixedly connected to the side of the second base, a slider slidably connected inside the slide rail, a connecting frame installed on the side of the slider, and the connecting frame fixedly connected to the end of the spiral heating tube body.

[0008] Preferably, two dampers are fixedly connected inside the slide rail. The two dampers are symmetrically distributed on both sides of the slider. A spring is provided on the surface of the damper. One end of the spring is fixedly connected to the inner wall of the slide rail, and the other end of the spring is fixedly connected to the side of the slider.

[0009] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0010] 1. In this utility model, the flexible connection design between the connecting hose and both ends of the spiral heating tube body creates a buffered elastic connection structure between the heating tube and the vehicle-mounted instant hot water dispenser body. When the vehicle is bumpy, the flexible deformation of the hose can absorb external vibration energy, avoiding the direct transmission of stress caused by rigid connection. It can also ensure the connection stability between the heating tube end and the equipment body, reducing the direct pulling and impact of vibration on the spiral section. Combined with the flexible wrapping support of the rubber vibration isolation pad on the inner side of the clamping block in the main body buffer mechanism, and the secondary buffering and absorption of vibration kinetic energy by the arc-shaped damping plate, the stress concentration effect of multidimensional vibration load on the curvature change part of the spiral section can be effectively attenuated. At the same time, the buffer rubber pad further forms elastic support for the heating tube as a whole, reducing the risk of structural resonance under vibration environment.

[0011] 2. In this utility model, the end of the heating tube is rigidly connected to the buffer structure through the connecting frame. When the vehicle vibration causes the heating tube to be impacted, the impact force is transmitted to the slider through the connecting frame, causing it to slide up and down along the slide rail. The multidimensional vibration is converted into controllable linear motion through the guiding effect of the slide rail. At the same time, the damper consumes the vibration kinetic energy by utilizing the viscous damping effect, and the spring absorbs and stores part of the impact energy through elastic deformation. The two work together to form a three-level buffer system of "sliding guidance - damping energy consumption - elastic buffer". Attached Figure Description

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Example 1: As Figures 1-4 As shown, this utility model provides a spiral heating tube structure for a vehicle-mounted instant hot water dispenser, including a spiral heating tube body 1, a main body buffer mechanism 3 installed inside the spiral heating tube body 1, and connecting hoses 2 fixedly connected to both ends of the spiral heating tube body 1. The main body buffer mechanism 3 includes a first base 31, a buffer rubber pad 32 fixedly connected to the upper part of the first base 31, a fixing plate 33 fixedly connected to the upper part of the buffer rubber pad 32, a fixing rod 34 fixedly connected to the upper part of the fixing plate 33, multiple fixing blocks 35 fixedly connected to the surface of the fixing rod 34, an arc-shaped shock-absorbing plate 36 fixedly connected to the side of the fixing block 35, and a clamping block 37 fixedly connected to the end of the arc-shaped shock-absorbing plate 36. The clamping block 37 clamps and fixes the spiral heating tube body 1, and an end buffer mechanism 4 is fixedly connected to the end of the spiral heating tube body 1. A rubber vibration isolation pad is fixedly connected inside the clamping block 37, and the rubber vibration isolation pad is tightly attached to the surface of the spiral heating tube body 1.

[0020] The specific settings and functions of this embodiment are described in detail below. The connecting hose 2 is fixedly connected to both ends of the spiral heating tube body 1. Then, the two connecting hoses 2 are respectively installed to the vehicle instant hot water dispenser body, so that the end of the spiral heating tube body 1 and the vehicle instant hot water dispenser body form a flexible connection. During use, when the spiral heating tube body 1 is subjected to external bumps, the stability of the connection between it and the vehicle instant hot water dispenser body is ensured, and the impact of bumps on the spiral section of the spiral heating tube body 1 is reduced.

[0021] The main buffer mechanism 3 reinforces and supports the spiral section of the spiral heating tube body 1. At the same time, the rubber vibration isolation pads provided on the inner side of the clamping block 37 effectively buffer and protect the spiral section of the spiral heating tube body 1. Meanwhile, the arc-shaped damping plate 36 buffers and absorbs the kinetic energy during vibration, reducing the vibration impact on the entire spiral heating tube body 1, especially the spiral section. Similarly, the buffer rubber pad 32 provides buffer protection for the entire spiral heating tube body 1.

[0022] By using a flexible connection design between the connecting hose 2 and both ends of the spiral heating tube body 1, a buffered elastic connection structure is formed between the heating tube and the vehicle-mounted instant hot water dispenser body. When the vehicle is bumpy, the flexible deformation of the hose can absorb external vibration energy, avoiding the direct transmission of stress caused by rigid connection. It can also ensure the connection stability between the heating tube end and the equipment body, reducing the direct pulling and impact of vibration on the spiral section. In conjunction with the flexible wrapping support of the spiral section by the rubber vibration isolation pad on the inner side of the clamping block 37 in the main body buffer mechanism 3, and the secondary buffering and absorption of vibration kinetic energy by the arc-shaped damping plate 36, the stress concentration effect of multidimensional vibration load on the curvature change part of the spiral section can be effectively attenuated. At the same time, the buffer rubber pad 32 further forms an elastic support for the entire heating tube, reducing the risk of structural resonance under vibration environment.

[0023] Example 2: Figures 1-4 As shown, the end buffer mechanism 4 includes a second base 41, a slide rail 42 fixedly connected to the side of the second base 41, a slider 43 slidably connected inside the slide rail 42, a connecting frame installed on the side of the slider 43, the connecting frame being fixedly connected to the end of the spiral heating tube body 1, two dampers 44 fixedly connected inside the slide rail 42, the two dampers 44 being symmetrically distributed on both sides of the slider 43, a spring 45 being provided on the surface of the damper 44, one end of the spring 45 being fixedly connected to the inner wall of the slide rail 42, and the other end of the spring 45 being fixedly connected to the side of the slider 43.

[0024] The overall effect of this embodiment is that an end buffer mechanism 4 is added to both ends of the spiral heating tube body 1. When the spiral heating tube body 1 is affected by vibration, the connecting frame at the end of the spiral heating tube body 1 transmits the kinetic energy of the impact to the slider 43. At this time, the slider 43 slides up and down along the slide rail 42. At the same time, the damper 44 and the spring 45 undergo expansion and contraction deformation to buffer the impact force on the spiral heating tube body 1 and protect the spiral heating tube body 1.

[0025] End buffer mechanisms 4, added at both ends of the spiral heating tube body 1, rigidly connect the heating tube ends to the buffer structure via connecting frames. When vehicle vibration causes the heating tube to be impacted, the impact force is transmitted to the slider 43 via the connecting frames, causing it to slide up and down along the slide rail 42. The multidimensional vibration is converted into controllable linear motion through the guiding effect of the slide rail 42. At the same time, the damper 44 consumes vibration kinetic energy using viscous damping effect, and the spring 45 absorbs and stores part of the impact energy through elastic deformation. The two work together to form a three-level buffer system of "sliding guidance - damping energy consumption - elastic buffer". This design can effectively attenuate the alternating load generated by vibration at the heating tube ends, avoid stress concentration caused by rigid fixation at the end connection, and, together with the main body buffer mechanism 3 supporting and protecting the spiral section, form an all-round anti-vibration structure of "flexible buffer at both ends + elastic support in the middle section". This significantly reduces the material fatigue risk and insulation layer damage probability of the heating tube bending parts under vibration environment, and improves the impact resistance and long-term operational reliability of the equipment under complex vehicle conditions.

[0026] The usage method and working principle of this device are as follows: The two ends of the spiral heating tube body 1 are fixedly connected by the connecting hose 2, and then the two connecting hoses 2 are respectively installed to the vehicle-mounted instant hot water heater body, so that the end of the spiral heating tube body 1 and the vehicle-mounted instant hot water heater body form a flexible connection. During use, when the spiral heating tube body 1 is subjected to external bumps, the stability of the connection between it and the vehicle-mounted instant hot water heater body is ensured, and the impact of bumps on the spiral section of the spiral heating tube body 1 is reduced.

[0027] The main buffer mechanism 3 reinforces and supports the spiral section of the spiral heating tube body 1. At the same time, the rubber vibration isolation pads set inside the clamping block 37 effectively buffer and protect the spiral section of the spiral heating tube body 1. Meanwhile, the arc-shaped damping plate 36 buffers and absorbs the kinetic energy during vibration, reducing the vibration impact on the entire spiral heating tube body 1, especially the spiral section. Similarly, the buffer rubber pad 32 buffers and protects the entire spiral heating tube body 1.

[0028] An end buffer mechanism 4 is added to both ends of the spiral heating tube body 1. When the spiral heating tube body 1 is affected by vibration, the connecting frame at the end of the spiral heating tube body 1 transmits the kinetic energy of the impact to the slider 43. At this time, the slider 43 slides up and down along the slide rail 42. At the same time, the damper 44 and the spring 45 undergo expansion and contraction deformation to buffer the impact force on the spiral heating tube body 1 and protect the spiral heating tube body 1.

[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
