Description

Technical Field

[0001] This utility model relates to the field of heater technology, specifically a rotary heater. Background Technology

[0002] A fan heater is a heating device that uses energy sources such as electricity, gas, or oil to drive a heating element to generate heat, which is then delivered to the surrounding space by a ventilation system, thereby quickly raising the temperature of a local or small area. It is usually small in size and easy to move. Its core structure includes a heating element (such as PTC ceramic or heating wire), a ventilation device (fan, air guide structure), a safety protection system (thermostat, tilt switch), and an operation panel. It is often used for temporary heating or supplemental heating in winter, or to quickly raise the temperature in spaces without fixed heating, to meet people's immediate need for localized comfortable temperatures. It also features fast heating speed and relatively controllable energy consumption, making it a common auxiliary heating tool in daily life.

[0003] However, existing space heaters are generally divided into two categories: rotary and stationary. Conventional rotary space heaters mostly rely on motors to drive the rotation of the body or air guide structure. Not only do motor components increase the purchase cost of the equipment, but the operation of the motor also increases energy consumption during long-term use, resulting in a higher overall operating cost. More importantly, the air delivery method of this type of space heater has obvious limitations. Its rotation is mostly around the horizontal direction, and the warm air discharged from the air outlet is mainly blown out directly along the horizontal path, making it difficult to achieve a wider range and more three-dimensional diffusion. For example, it cannot reach both low-temperature areas near the ground and high spaces. Hot air tends to accumulate in local areas and cannot evenly cover the entire usage scenario. Ultimately, this leads to significant temperature differences in different areas of the room. Areas near the space heater may be too hot, while areas further away or at lower temperatures may still feel cold, making it difficult to meet users' needs for uniform heating throughout the entire area. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] In view of the problems mentioned above and / or existing heaters, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a rotating air heater.

[0007] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: A rotating air heater includes a base. The outer wall of the top of the base is provided with a guide mechanism for driving a fixed shell to swing up and down. The guide mechanism includes a first connecting shell, a connecting frame, and a second connecting shell. A guide groove is formed between the first and second connecting shells. A rotating frame is rotatably connected to the top of the base. A movable frame is rotatably connected to the inner wall of the rotating frame. A heating air assembly is fixedly installed on the outer wall of the movable frame. The heating air assembly includes a mounting shell installed on the outer wall of the movable frame. A mounting frame is provided at the bottom of the mounting shell. A transmission mechanism for driving the mounting shell to swing up and down is provided between the mounting frame and the guide groove. The transmission mechanism includes a sliding frame. An inclined air outlet pipe is provided on the outer wall of the mounting shell for driving the rotating frame to rotate using exhaust power.

[0008] In a preferred embodiment of the rotary heater described in this utility model, the connecting frame is disposed on the outer circumferential wall of the first connecting shell and the second connecting shell, and the guide groove is wavy.

[0009] In a preferred embodiment of the rotary heater described in this utility model, a fan is provided on one outer wall of the mounting housing, and an electric heating element is provided on the inner wall of the mounting housing.

[0010] In a preferred embodiment of the rotary air heater described in this utility model, the inclined air outlet pipe is inclined at 45° to the right, and both the inclined air outlet pipe and the fan are connected to the interior of the mounting housing.

[0011] In a preferred embodiment of the rotary heater described in this utility model, a rotating roller is rotatably connected to one side of the outer wall of the sliding frame, and the rotating roller extends into the guide groove.

[0012] In a preferred embodiment of the rotary heater described in this utility model, through openings are provided on the outer walls of both sides of the mounting frame, and a rotating roller is rotatably connected to the top of the sliding frame.

[0013] In a preferred embodiment of the rotary heater described in this utility model, a plurality of rotating rollers are symmetrically rotated and connected to the outer wall of the sliding frame, and the plurality of rotating rollers extend into the interior of the through-hole.

[0014] Compared with existing technologies, the advantages of this invention are as follows: Firstly, in practical use, this device abandons the traditional motor-driven rotation mode. Instead, it discharges heated air at a 45° angle, utilizing the thrust generated by the airflow to directly drive the mounting shell of the heating device to rotate autonomously. This eliminates the need for motor components and energy costs, simplifies the transmission structure, and reduces subsequent maintenance requirements. Secondly, to overcome the limitation of traditional rotary heaters that can only deliver air horizontally, the transmission mechanism of this device incorporates a wave-shaped guide groove and a matching rotating roller. When the device rotates with the help of airflow thrust, the first rotating roller moves along the undulating trajectory of the wave-shaped guide groove, thereby synchronously driving the sliding frame to move up and down reciprocally. The second rotating roller on both sides of the top of the sliding frame slides along the through-holes on both sides of the equipment mounting frame as the sliding frame rises and falls. Ultimately, this drives the inclined air outlet pipe to achieve dynamic changes in vertical amplitude while rotating and distributing air, so that the warm air is no longer limited to the horizontal direction, but can cover the three-dimensional space from the ground to the air, greatly improving the uniformity and coverage of the warm air diffusion, and effectively avoiding the problems of local overheating or low temperature dead zones.

Detailed Implementation

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0021] This utility model provides a rotating air heater, including a base 100. The top outer wall of the base 100 is provided with a guide mechanism for driving a fixed shell to swing up and down. The guide mechanism includes a connecting shell 110, a connecting frame 120, and a connecting shell 2 130. A guide groove 140 is formed between the connecting shell 110 and the connecting shell 2 130. A rotating frame 200 is rotatably connected to the top of the base 100. A movable frame 210 is rotatably connected to the inner wall of the rotating frame 200. A heating assembly is fixedly installed on the outer wall of the movable frame 210. The heating assembly includes a mounting shell 300 installed on the outer wall of the movable frame 210. A mounting frame 340 is provided at the bottom of the mounting shell 300. A transmission mechanism for driving the mounting shell 300 to swing up and down is provided between the mounting frame 340 and the guide groove 140. The transmission mechanism includes a sliding frame 350. An inclined air outlet pipe 330 is provided on the outer wall of the mounting shell 300 for driving the rotating frame 200 to rotate by the power of exhaust.

[0022] In this embodiment, the base serves as the overall support foundation for the device, and a guide mechanism for driving the warm air assembly to swing up and down is fixedly installed on the top outer wall. The connecting shell 110 and the connecting shell 2 130 are coaxially arranged annular shells, and the connecting frame 120 is fixedly connected to the outer circumference of the two to form an annular frame structure. A gap is reserved between the relative inner walls of the connecting shell 110 and the connecting shell 2 130 to form a wave-shaped guide groove 140. The wave undulation trajectory of the guide groove 140 provides a guide path for the subsequent transmission mechanism to move up and down, and the amplitude and frequency of the wave can be designed according to the actual air supply requirements to ensure that the swing amplitude is adapted to different usage scenarios.

[0023] In this embodiment, the rotating frame 200 and the movable frame 210 are included. The rotating frame 200 is rotatably connected to the top center of the base 100 via bearings and can rotate 360° horizontally around the axis of the base. The rotating frame 200 has a U-shaped frame structure, and its two side walls are rotatably connected to the outer wall of the movable frame 210 via pivots, so that the movable frame 210 can flip up and down relative to the rotating frame 200, providing a support base for the up and down swing of the heating element.

[0024] In this embodiment: The heating air assembly is fixedly installed on the outer wall of the movable frame 210 and is the core component for generating and conveying hot air. It includes a mounting shell 300, a fan 310, an electric heating element 320, an inclined air outlet duct 330, and a mounting frame 340. The mounting shell 300 is a hollow rectangular shell with reserved air duct space inside. The fan 310 is embedded in one of its outer walls. The air outlet of the fan 310 is connected to the inside of the mounting shell 300 to draw cold air from outside into the mounting shell 300. The electric heating element 320 is horizontally fixed inside the mounting shell 300 near the air outlet of the fan 310. The electric heating element 320 is made of alloy heating material and can quickly convert electrical energy into heat after being powered on. Yes, it can heat the cold air drawn in by the fan 310; the outer wall of the mounting shell 300 away from the fan 310 is integrally formed with an inclined air outlet 330, which is connected to the internal air duct of the mounting shell 300, and its air outlet is inclined to the right at 45°. The inclination angle can be selected according to the airflow back thrust requirement. When the hot air is discharged through the inclined air outlet 330, it can generate a horizontal back thrust, which provides power for the rotation of the rotating frame 200 without the need for an additional motor drive; the bottom outer wall of the mounting shell 300 is fixedly connected to the mounting frame 340 by bolts, and its two vertical outer walls are symmetrically provided with long strip-shaped through openings to provide a channel for the movement of the subsequent transmission mechanism.

[0025] Specifically, the connecting frame 120 is disposed on the outer circumference of the connecting shell 110 and the connecting shell 2 130, and the guide groove 140 is wavy.

[0026] Specifically, a fan 310 is provided on the outer wall of one side of the mounting shell 300, and an electric heating tube 320 is provided on the inner wall of the mounting shell 300.

[0027] Specifically, the inclined air outlet duct 330 is tilted to the right at 45°, and both the inclined air outlet duct 330 and the fan 310 are connected to the interior of the mounting housing 300.

[0028] Specifically, a rotating roller 351 is rotatably connected to one side of the outer wall of the sliding frame 350, and the rotating roller 351 extends into the guide groove 140.

[0029] Specifically, the mounting frame 340 has through openings on both outer walls, and the top of the sliding frame 350 is rotatably connected to a rotating roller 352.

[0030] Specifically, multiple rotating rollers 352 are symmetrically rotated and connected to the outer wall of the sliding frame 350, and the multiple rotating rollers 352 extend into the through-hole.

[0031] In this embodiment: the transmission mechanism is disposed between the mounting frame 340 and the guide groove 140, and is used to convert the rotational motion of the rotating frame 200 into the up-and-down swinging motion of the heating element. The core includes a sliding frame 350, a first rotating roller 351 and a second rotating roller 352. The first rotating roller 351 is rotatably connected to one side of the outer wall of the sliding frame 350 via a rotating shaft. The diameter of the first rotating roller 351 is adapted to the width of the guide groove 140, and the first rotating roller 351 extends into the interior of the guide groove 140, and can roll along the wave trajectory of the guide groove 140. The outer wall of the sliding frame 350 is also symmetrically connected to the left and right sides via a rotating shaft. Multiple rotating rollers 352 are connected. The diameter of the rotating rollers 352 is adapted to the width of the through-hole of the mounting frame 340, and the rotating rollers 352 extend into the through-hole and can slide along the length of the through-hole. The through-hole has a certain inclination angle, which makes it easier for the sliding frame 350 to move better along the through-hole during the upward process. When the rotating rollers 351 roll along the wave-shaped guide groove 140, the sliding frame 350 will move up and down with the undulation of the guide groove 140, and then the rotating rollers 352 push the mounting frame 340 to drive the entire heating assembly to swing up and down to a certain extent.

[0032] In some embodiments, a controller (such as a touch panel or button controller) is also fixedly installed on the outer wall of the mounting housing 300 to control the device's power on / off, fan speed, heating level of the electric heating element, and other functions, making it convenient for users to operate directly. At the same time, the device can be powered by an external power supply, and the power supply line and signal transmission line are electrically connected through a conductive slip ring (the conductive slip ring is installed at the rotation connection between the rotating frame 200 and the base 100), ensuring stable power supply and continuous signal transmission during the rotation of the rotating frame 200. The above power supply and signal connection methods are all existing technologies and will not be described in detail here.

[0033] In this embodiment, the device, in actual use, firstly abandons the traditional motor-driven rotation mode, instead expelling heated air at a 45° angle. The reverse thrust generated by the airflow directly drives the mounting shell 300 of the heating device to rotate autonomously. This eliminates the purchase and energy costs of motor components, simplifies the transmission structure, and reduces subsequent maintenance needs. Secondly, to overcome the limitation of traditional rotary heaters that can only deliver air horizontally, the device's transmission mechanism is equipped with a wave-shaped guide groove 140 and a matching rotating roller 351. When the device rotates using the reverse thrust of the airflow... The rotating roller 351 moves along the undulating trajectory of the wave-shaped guide groove 140, thereby synchronously driving the sliding frame 350 to move up and down. The rotating rollers 352 on both sides of the top of the sliding frame slide along the through openings on both sides of the equipment mounting frame 340 as the sliding frame 350 rises and falls. This ultimately drives the inclined air outlet duct 330 to achieve dynamic changes in its vertical amplitude while rotating and distributing air, so that the warm air is no longer limited to the horizontal direction, but can cover the three-dimensional space from the ground to the air, greatly improving the uniformity and coverage of the warm air diffusion, and effectively avoiding the problems of local overheating or low temperature dead zones.

[0034] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
