Description

Technical Field

[0001] The utility model relates to the technical field of liquid transportation, in particular to an environmentally friendly hose heating device. Background Art

[0002] The hose of a fuel dispenser is usually used to connect the pipeline between the fuel tank and the fuel nozzle. It is a soft tubular structure made of oil-resistant and chemical-resistant materials such as polyester, polyurethane or rubber. These materials can resist the corrosion and high temperature of the fuel and have a certain elasticity and pressure resistance to ensure the safety and reliability of fuel transmission. The hose is also often equipped with anti-static equipment to prevent the risk of fire caused by static electricity.

[0003] When refueling in the cold winter, the oil in the hose will increase in viscosity due to the influence of temperature at low temperatures, making its fluidity worse. If the temperature is low, such as the weather in northern my country, some oils will freeze and wax, which may cause the refueling speed to slow down or even cause normal refueling in extreme cases. Therefore, we have proposed an environmentally friendly hose heating device to solve the above problems. Utility Model Content

[0008] An environmentally friendly hose heating device comprises a temperature controller and a sleeve hose arranged on the outside of the hose, a heating cable is embedded in the inner wall of the sleeve hose, the heating cable is in contact with the outer wall of the hose, the heating cable is electrically connected to an external power supply through the temperature controller, and an insulation layer is arranged on the outside of the sleeve hose.

[0009] Furthermore, a notch is provided on the sleeve hose, and buckle pieces that fit together are provided on both sides of the notch, and the side where the buckle pieces fit together is an arc-shaped surface extending outward from the top.

[0010] Furthermore, the heating cable is coiled along the inner wall of the sleeve hose, leaving a gap corresponding to the notch of the hose.

[0011] Furthermore, thermal insulation cotton is filled between the two snap-in pieces, and the thermal insulation cotton is bonded and fixed to one of the snap-in pieces.

[0012] Preferably, the inner wall of the sleeve hose is provided with a plurality of fixed teeth.

[0013] Preferably, the sleeve hose is made of polypropylene or polytetrafluoroethylene.

[0014] Preferably, the thermal insulation layer is glass fiber cloth.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] In cold weather, a sleeve hose can be sleeved on the outside of the hose. The heating cable in the sleeve hose fits the outer wall of the hose. Under the control of the thermostat, the hose is powered on to heat up. At the same time, the setting of the insulation layer can reduce heat leakage, achieve energy-saving and environmental protection effects, and prevent the oil inside the hose from having poor fluidity due to low temperature or even freezing and waxing, so as not to affect the refueling speed. At the same time, due to the setting of the sleeve hose notch and the snap piece, the device can be buckled from the side wall of the hose to the outside, making disassembly and assembly more convenient.

[0023] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. It should be noted that the words "front", "back", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the words "bottom surface" and "top surface", "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] Embodiment 1

[0025] See also Figure 1-4 As shown, the utility model provides an environmentally friendly hose heating device, including a thermostat, a sleeve hose 2, a heating cable 3, fixed teeth 4, and a thermal insulation layer 5. The sleeve hose 2 is coated on the outside of the hose 1, and the heating cable 3 is laid around the inner wall of the sleeve hose 2 and embedded in the inner wall thereof, with one side thereof in close contact with the hose 1. The heating cable 3 can be connected to an external power supply through a thermostat, and the heating cable 3 is powered by the external power supply to release heat, and the switch is controlled by the thermostat. The thermostat can adopt a controller such as an AZ43 liquid crystal thermostat that plays a temperature control role. The thermal insulation layer 5 is coated on the outside of the sleeve hose 2 to reduce heat leakage, thereby playing an energy-saving and environmental protection role. The sleeve hose 2 is made of polypropylene or polytetrafluoroethylene material, which has excellent chemical corrosion resistance and high temperature resistance. The thermal insulation layer 5 adopts glass fiber cloth, which has high insulation and thermal insulation properties, high wear resistance, and long service life.

[0026] Embodiment 2

[0027] On the basis of Example 1, in order to facilitate the sleeve hose 2 to be wrapped around the hose 1, a through notch is opened on the sleeve hose 2 along its axial direction, and buckle pieces 6 that fit each other on one side are symmetrically arranged on both sides of the notch. The buckle pieces 6 are arc-shaped pieces, and their tops are curled and extended toward the side away from the notch to facilitate buckling. Insulation cotton 7 is arranged between the two buckle pieces 6. The insulation cotton 7 is used to fill the gap between the two buckle pieces 6 and the hose 1 to reduce heat leakage. During installation, the tops of the two buckle pieces 6 can be attached to the hose 1, and then the sleeve hose 2 can be pinched and clamped to the outside of the hose 1 from the hose 1, and vice versa. Compared with inserting from one end of the hose 1, the disassembly and assembly process is more convenient and quick.
