Description

Technical Field

[0001] This invention relates to the field of heater technology, specifically to a high-efficiency heater and its heat sink. Background Technology

[0002] A heater is a device used for heating. Heating devices vary depending on the heating medium and heating principle. The term "heater" is a general term that covers a variety of heating devices, including fan heaters, oil radiators, small sun heaters (radiant heaters), electric heating films, electric blankets, etc. Among them, fan heaters are heating devices that use a fan to force hot air to be blown out. Fan heaters are characterized by their fast heating speed.

[0003] For example, Chinese utility model patent application number 202420782819.7, entitled "Warm Fan," discloses a warm fan, relating to the field of warm fan technology. The warm fan includes a housing, a mounting bracket, a heating module, a fan assembly, and a main board. The housing has a receiving cavity, and the mounting bracket is disposed within the receiving cavity. The mounting bracket includes a first mounting bracket and a second mounting bracket. The heating module is mounted on the first mounting bracket, and the fan assembly is connected to the first mounting bracket and spaced apart from the heating module. The main board is mounted on the second mounting bracket and is electrically connected to the heating module and the fan assembly. This warm fan, by mounting the heating module and fan assembly on the first mounting bracket, reduces the number of installation parts and simplifies the installation process. Furthermore, the warm fan has a compact structure and a reasonable layout.

[0004] The shortcomings of existing technologies are as follows: Existing space heaters have the advantage of rapid heating, but the air outlet position is fixed, and the temperature at the air outlet is higher. In order to facilitate heating of the surrounding environment, a rotating fin is usually set at the air outlet position to assist in heating the surrounding environment. The fin rotates back and forth to adjust the output position of the warm air. When the fin moves away, the heat source is cut off and disappears, resulting in low efficiency of space heaters for rapid heating in large areas. Some space heaters increase the equipment area or adopt a folding design in order to cover the heating area, which not only increases the equipment's footprint but also increases energy consumption, thus having certain shortcomings. Summary of the Invention

[0005] The purpose of this invention is to provide a high-efficiency heater and its heat sink to overcome the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency heater, comprising a heater outer shell composed of a first shell, a second shell, and a third shell. A heating element and a fixed fan are installed in the first shell, and an air supply assembly is provided on the fixed fan. A second heating element and an outer shell plate are installed on the second shell. When the first and second heating elements are arranged in a front-to-back configuration, the heating efficiency of the heater is enhanced. When the second shell moves and is adjusted at multiple angles, the air supply assembly adaptively adjusts to blow out the heat generated on the second heating element, thereby increasing the heating area of ​​the heater.

[0016] A top plate is fixedly connected to the second housing, and a sliding rod is fixedly connected to the top plate. A limiting groove is provided on the first housing, and the sliding rod slides in the limiting groove.

[0017] As a further description of the above technical solution:

[0018] The first housing is also provided with a snap-fit ​​assembly for fixing the second housing. The snap-fit ​​assembly includes two linkage plates that are slidably connected in the first housing. The first housing is also provided with a cross frame, the two ends of which are movably connected to the two linkage plates respectively. A positioning rod is fixedly connected to one of the linkage plates. The top plate is provided with a plurality of positioning holes that are adapted to the positioning rod. A trigger block is fixedly connected to the other linkage plate. A support spring is provided between the trigger block and the first housing.

[0019] As a further description of the above technical solution:

[0020] The first housing has an installation groove, the third housing has a connecting block fixedly connected to it, the connecting block has a vertical rod fixedly connected to it, the vertical rod is movably connected in the installation groove, and an elastic rope is also provided between the third housing and the first housing.

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0043] Please see Figure 1-11 This embodiment provides a high-efficiency heater, comprising a heater shell composed of a first shell 11, a second shell 12, and a third shell 13. The first shell 11 houses a heating element 14 and a fixed fan 15, with an air supply assembly mounted on the fixed fan 15. The second shell 12 houses a heating element 16 and an outer shell plate 17. The first shell 11, second shell 12, third shell 13, heating element 14, and fixed fan 15 are important components of existing heaters. When the heating element 14 and heating element 16 are arranged front-to-back, the heating efficiency of the heater is enhanced. When the heating element 14 and heating element 16 are arranged front-to-back, the fixed fan 15 and the air supply assembly are located behind them. The fixed fan 15 and the air supply component are arranged vertically. The fixed fan 15 and the air supply fan work together to blow the heat generated by both, improving the overall heating effect. When the housing 12 moves and is adjusted at multiple angles, the air supply component adapts and adjusts accordingly so that the air supply component can blow out the heat generated on the heating element 16, increasing the heating area of ​​the heater. The housing 12 can be completely pulled out from the housing 11 and rotated according to the usage requirements. At the same time as the housing 12 moves, it drives the heating element 2 to move, and drives the air supply component to move as well, so that the air supply component can automatically adapt and adjust its position, and work with the heating element 2 to heat up quickly from multiple angles and over a large area, which has strong practicality.

[0044] In a further embodiment of the present invention, the air supply assembly includes a rotating plate 21 rotatably connected to the output shaft of a fixed fan 15, and a rotating plate 22 rotatably connected to one end of the rotating plate 21. A guide rod 23 is fixedly connected to the rotating plate 22, and a mounting plate 24 is fixedly connected to the guide rod 23. A movable fan 25 is mounted on the mounting plate 24 and is driven by an external drive source. An arc groove 26 is provided on a housing 11, and an arc groove 27 is provided on a housing 3. The arc groove 26 and the arc groove 27 are connected and both are adapted to the guide rod 23. When the arc groove 1 and the arc groove 2 are connected, they form a quarter arc of a circle. Both sides of the guide rod 23 are fixedly connected to... An L-shaped rod 3 is connected, and grooves adapted to the L-shaped rod 3 are opened in both housing 11 and housing 3. The grooves for the movement of the L-shaped rod 3 opened in housing 11 and housing 2 are consistent with the shape of arc groove 1 26 and arc groove 2 27. The L-shaped rod 3 and the groove are set to restrict the rotation of the guide rod 23. A fixing plate 41 is also fixedly connected in housing 2. A track groove 42 is opened on the fixing plate 41. The guide rod 23 slides in the track groove 42. The track groove 42 is composed of inclined grooves and horizontal grooves. When housing 2 moves, it drives the fixing plate 41 to move. Through the inclined groove part of the track groove 42, the guide rod 23 can be driven to move along arc groove 1 26 to arc groove 27.

[0045] In a further embodiment of the present invention, a top plate 51 is fixedly connected to the second housing 12, and a sliding rod 52 is fixedly connected to the top plate 51. A limiting groove 53 is formed on the first housing 11, and the sliding rod 52 slides in the limiting groove 53. A snap-fit ​​assembly for fixing the second housing 12 is also provided on the first housing 11. The snap-fit ​​assembly includes two linkage plates 61 slidably connected in the first housing 11, and a cross bracket 62 is also provided in the first housing 11. The two ends of the cross bracket 62 are respectively movably connected to the two linkage plates 61. A positioning rod 63 is fixedly connected to one of the linkage plates 61, and a plurality of positioning holes 64 adapted to the positioning rod 63 are provided on the top plate 51; the other A trigger block 65 is fixedly connected to the linkage plate 61. A support spring 66 is provided between the trigger block 65 and the housing 11. The locking assembly facilitates the limiting and fixing of the moving housing 2 12. The positions of the positioning hole 64 are as follows: when the housing 2 12 is completely attached to the housing 11, the positioning rod 63 is locked with the preset positioning hole 64 on the top plate 51; when the housing 2 12 slides completely out of the housing 11, the positioning rod 63 is locked with the preset positioning hole 64 on the top plate 51; when the housing 2 12 slides out and rotates a certain angle (less than 90°), the positioning rod 63 is locked with the preset positioning hole 64 on the top plate 51.

[0046] In the embodiments provided by the present invention, a mounting groove 71 is provided on the first housing 11, a connecting block 72 is fixedly connected to the third housing 13, a vertical rod 73 is fixedly connected to the connecting block 72, the vertical rod 73 is movably connected in the mounting groove 71, and an elastic rope 74 is also provided between the third housing 13 and the first housing 11. The elastic force of the elastic rope 74 drives the third housing 13 and the first housing 11 to move closer to each other. When the second housing 12 moves laterally, one end of the horizontal groove of its track groove 42 contacts the guide rod 23, the guide rod 23 can drive the third housing 13 to move and separate from the first housing 11. The second housing 12 is provided with a pusher to push the third housing 13 to rotate, which facilitates the second housing 12 to drive the third housing 13 to rotate later for heating work over a larger and wider area.

[0047] In a further embodiment of the present invention, a motor 81 is fixedly connected in the housing 11. The output end of the motor 81 is connected to the output shaft of the fixed fan 15 via an internal toothed belt 82. Both the output end of the motor 81 and the output end of the fixed fan 15 are provided with pulleys adapted to the internal toothed belt 82. By setting the internal toothed belt 82 for transmission, the motor 81 can be set to other positions to avoid affecting the movement of the fixed plate 41.

[0048] A heat sink includes a heat sink fin body 9, which is wrapped around the outside of a heating wire. The distance between adjacent heat sink fin bodies 9 on the side closer to the fixed fan 15 is greater than the distance between the other sides. Heat sink fin bodies 9 can be added on the other side. The fin spacing on the heat sink fin body 9 on the side closer to the fixed fan 15 is ≥5mm to ensure smooth airflow. The fins on the other side are denser to facilitate improved heat exchange intensity.

[0049] Working principle: When heating efficiency needs to be increased in one area, heating element 14 and heating element 26 work synchronously. The fixed fan 15 and the mobile fan 25 deliver airflow, achieving rapid and efficient heating. When heating a larger space is needed, pressing the trigger block 65 on housing 11 causes the connected linkage plate 61 to move downwards. The cross bracket 62 then drives the other linkage plate 61 to move upwards, separating it from the positioning hole 64 on the top plate 51. At this point, pulling housing 212 moves heating element 2, outer shell 17, and fixing plate 41 out of housing 11. As fixing plate 41 moves, its track groove 42 drives guide rod 23 to move along the shape of arc groove 26 until it enters the arc groove 2. At this point, the mobile fan moves to the outside of heating element 2. The heating element 12 is used to discharge the heat generated by the second heating element, increasing the overall heating area. When the second housing 12 continues to move, the fixed plate 41 can drive the third housing 13 to move synchronously. When the third housing 13 moves in the first housing 11, it will pull the elastic rope 74 to deform. At this time, the second housing 12 is rotated so that the second heating element rotates and is not on the same plane as the first heating element, which can further expand the heating range. When the second housing 12 rotates, the third housing 13 is driven to rotate by the pusher set on it. The rotation of the third housing 13 is driven to rotate by the arc groove 27 and the upper groove of the L-shaped rod 3. At this time, the rotating rod plate 1 set on the guide rod 23 rotates so that the mobile fan automatically adapts to the rotating second heating element, further increasing the heating area of ​​the heater. This ensures that the heater is no longer limited to heating only one plane and avoids the insufficiency of heat diffusion caused by the rotation of the fins.

[0050] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
