Description

Technical Field

[0001] The present invention relates to the technical field of electric heaters, and particularly relates to an efficient and energy-saving graphene electric heater. Background Art

[0002] In cold winters, people generally use electric heaters indoors for heating. An electric heater is an auxiliary device that can be widely used for heating in various civilian and public buildings such as residences, offices, hotels, shopping malls, hospitals, schools, and mobile places such as train carriages, as well as simple movable houses. Electric heaters use electric energy as the main energy source and use methods such as resistance heating, induction heating, arc heating, electron beam heating, infrared heating, and dielectric heating. For graphene electric heaters, compared with traditional resistance heating materials, graphene does not have problems such as power failure breakdown and obvious decline in aging power. Different from conventional heating films, the graphene electrothermal film electric heater has stable and safe heating, and the infrared rays emitted are called life rays. Moreover, if a conventional heating film fails or is damaged, it cannot be used anymore. However, due to the overall heat generation property of the graphene heating film, even if there is a hole or a piece is cut off, as long as there is still a part that can connect the positive and negative electrodes, it can continue to heat. Therefore, it is very reliable to use graphene materials for electrothermal films, and it can quickly adjust the indoor temperature and provide heating, achieving high efficiency and energy saving. However, when existing graphene electric heaters are in use, most of them are placed on the ground through a bottom support frame, resulting in a relatively short and fixed height of the graphene electric heater, which is not convenient for users to adjust the height of the electric heater according to the heating needs of different body parts, and is not convenient for moving around. Therefore, it is urgent to design an efficient and energy-saving graphene electric heater to solve the above problems. Summary of the Invention

[0038] Working steps: First, when it is necessary to adjust the height of the electric heater main body 3, by rotating one of the rotating knobs 42 to drive one of the worms 30 to rotate. The rotation of the worm 30 can drive the connected first sprocket 31 to rotate. The rotation of the first sprocket 31 can drive another first sprocket 31 to rotate through the first chain 32, so that the two first sprockets 31 and the two worms 30 rotate synchronously. The synchronous rotation of the two worms 30 can drive the two worm wheels 29 to rotate synchronously. The synchronous rotation of the two worm wheels 29 can drive the two lead screws 26 to rotate synchronously. The rotation of the lead screw 26 can drive the lifting rod 27 to move up and down along the inner wall of the fixed cylinder 25. The up and down movement of the lifting rod 27 can drive the connecting plate 28 to move up and down. The up and down movement of the connecting plate 28 can drive the electric heater main body 3 to move up and down, thereby quickly adjusting the height of the electric heater main body 3, improving the convenience of adjusting the electric heater main body 3 at high speed.

The up and down movement of the threaded rod 8 can drive the contact plate 9 and the anti-slip pad 10 to move. By contacting the contact plate 9 and the anti-slip pad 10 with the ground, the bottom plate 5 can be fixed and limited. Among them, when rotating one threaded cylinder 7, the other threaded cylinder 7 can be driven to rotate synchronously through the two second sprockets 13 and the second chain 14, so that the two threaded rods 8 can drive the two contact plates 9 and the two anti-slip pads 10 to contact the ground synchronously; Third, when using the main body 3 of the electric heater for heating, cold air enters the housing 17 through the air inlet 22, and then is heated by the graphene heating plate 20 and the heat sink 21 and then dissipated through the air outlet net plate 19. The heating temperature of the graphene heating plate 20 can be controlled by the control module 18; Fourth, when blocking the air outlet net plate 1, by rotating the baffle 4, the insertion block 35 is inserted into the insertion slot 34. Then, the clamping rod 38 is pulled upward so that the clamping rod 38 retracts into the notch 37. Then, the insertion block 35 is completely inserted into the insertion slot 34. At this time, the clamping rod 38 is released so that one end of the clamping rod 38 is inserted into the insertion slot 34 to fix the baffle 4, so that the baffle 4 blocks the air outlet net plate 19.
