Technical Field

[0001] This utility model relates to the field of heating technology, and in particular to an auxiliary heating air convection device. Background Technology

[0002] As temperatures gradually cool, people often rely on air conditioning for indoor heating during the cold season. Air conditioning typically works by compressing a refrigerant (mainly Freon) using a compressor. After compression, the Freon becomes a high-temperature, high-pressure gas. This gas then enters the condenser of the indoor unit, where it condenses and releases a large amount of heat, raising the indoor air temperature and thus achieving indoor heating.

[0003] However, traditional heating methods have some obvious problems in practical applications. Because the heating efficiency is greatly affected by the ambient temperature, the temperature in some areas is too high, while the temperature in areas far away from the device is low, which affects the uniformity of the heating effect. At the same time, there may be overheating, short circuit or fire hazards when working at high temperatures for a long time. Utility Model Content

[0030] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0031] like Figures 1 to 6As shown, this utility model discloses an auxiliary heating air convection device, including a motor 1 and a rotating shaft 2 connected to the output end of the motor 1. The motor 1 provides power to the entire device. It also includes a base 3 for support and fixation, ensuring the stability of the device during operation. The base 3 can be a cuboid or a cylindrical structure, adaptable as needed; this application does not impose further limitations on this. A ventilation device 4 for heat transfer is provided on the top of the base 3. Both the ventilation device 4 and the motor 1 are rotatably connected to the base 3. During use, the air convection device can adjust the airflow direction within a certain range to adapt to different usage scenarios. The ventilation device 4 includes a ventilation duct 41 and a heating device 42 located within the ventilation duct 41. The ventilation duct 41 guides and restricts airflow, and the heating device 42... The heating device 42 is responsible for heating the air in the ventilation duct 41 and delivering the hot airflow to the desired location, thereby increasing the temperature of the output airflow. The shaft 2 of the motor 1 is connected to multiple fan blades 6 through a slip ring 5 to generate forced convection of the surrounding air. The fan blades 6 can be quadrilateral or wing-shaped, etc. During use, the operator turns on the heating device 42 to generate heat. At the same time, the heating device 42 can deliver the heat along the ventilation duct 41 to the fan blades 6. The air outlet of the ventilation duct 41 faces the multiple fan blades 6. When the fan blades 6 rotate, the heat generated by the heating device 42 is blown by the ventilation duct 41 to the desired area, thereby achieving a heating effect.

[0032] In some embodiments, the location of the ventilation device 4 can be adapted as needed; for example, in one instance, such as... Figures 1 to 2As shown, the ventilation device 4 is installed at the bottom of the motor 1, that is, the ventilation device 4 is located between the motor 1 and the base 3. The ventilation pipe 41 has an L-shaped structure and is mainly composed of a fixed part 411 and a rotating part 412. The L-shaped ventilation pipe 41, through the cooperation of the fixed part 411 and the rotating part 412, can maintain the stability of the heating device 42 and flexibly adjust the hot air output direction, improving the applicability of the air supply. The fixed part 411 is fixedly connected to the base 3 through the heating device 42. The fixed connection can be a threaded connection or welding, etc. The heating device 42 is fixedly connected to the base 3 through the fixed part 411. 1. The rotating part 412 is connected to the outside. The connection between the heating device 42 and the base 3 has an air inlet, which facilitates the intake of outside air into the ventilation duct 41 by the heating device 42. The rotating part 412 is located on the side wall of the motor 1. Both the rotating part 412 and the motor 1 are rotatably connected to the fixed part 411. The rotatable connection can be a crank-rocker mechanism or a worm gear connection, so that the motor 1 and the rotating part 412 can swing at a preset angle. The preset angle can be any value within 80° to 160°, thereby heating the air within the required range. In another example, the motor 1 is rotatably connected to the fixed part 411 of the ventilation duct 41 through a worm gear. The fixed part 411 and the rotating part 412 are fixedly connected and internally connected. The rotating part is a bellows with high flexibility and high strength, which can be bent and adapt to complex shapes. One end of the bellows is fixed to the bottom of the motor 1. During use, the drive motor 1 drives the fan blades 6 along the circumference of the fixed part 411 (e.g., ...). Figure 1 As shown in the H direction, the rotating part 412 swings along with the motor 1, thereby effectively delivering hot air to the desired area.

[0033] In yet another example, such as Figure 3 and Figure 4 As shown, the ventilation device 4 is installed on the side wall of the motor 1, and the extension direction of the ventilation pipe 41 of the ventilation device 4 (as shown) Figure 4 (as shown in the x-direction) and the axis of rotation 2 (as shown in the x-direction) Figure 4 As shown in the x direction, the ventilation duct 41 is parallel to the heating device 42 and the other end faces multiple fan blades 6. The motor 1 is connected to the support rod 31 of the base 3 through the swing mechanism. In the assembled state, the swing mechanism is driven to make the motor 1 and the ventilation device 4 reciprocate along a preset angle.

[0034] In some embodiments, continue to refer to Figures 1 to 4The heating device 42 includes an axial flow motor 420 for generating airflow and a heating element 421 for generating heat. The heating element 421 can be an electric heating wire or a PTC element, etc., and can be adapted as needed. The axial flow motor 420 is installed at one end of the ventilation duct 41. The axial flow motor 420 drives the airflow by rotating, allowing external air to enter the ventilation duct 41 and pushing the air along the ventilation duct 41. The heating element 421 is installed inside the ventilation duct 41 to heat the air flowing through the ventilation duct 41, raising its temperature to achieve the desired heating effect. During device operation, the drive shaft... The axial flow motor 420 has blades that rotate at high speed to form a stable airflow, drawing in external cold air into the ventilation duct 41. As the air passes through the ventilation duct 41, it flows through the heating element 421 and gradually increases in temperature. The heated air then continues to move along the flow direction of the ventilation duct 41 and is finally discharged from the air outlet 410. The heated air is then transported to the required area by the fan blades 6, thus achieving the function of heating and transporting air outward. The entire process ensures that the air is fully heated. At the same time, the continuous drive of the axial flow motor 420 ensures that the hot air is stably and evenly transported to the target area to meet specific heating requirements.

[0035] In some embodiments, such as Figure 1 and Figure 6 As shown, the surface of the fan blade 6 is provided with a heating coating 7. The heating coating 7 is made of a special material with electric heating function, which can rapidly heat up after being powered on and evenly transfer heat to the surface of the fan blade 6, thereby improving the air heating effect. During operation, as the fan blade 6 rotates, the heating coating 7 directly heats the air passing through it, raising its temperature. Furthermore, due to the continuous rotation of the fan blade 6, the heat is carried to a wider area, promoting air convection and circulation, thus improving the overall heating efficiency of the space. Compared to traditional heating methods, the design of the heating coating 7 achieves a more uniform and efficient heating effect, while reducing localized overheating and improving comfort.

[0036] The heating coating 7 is typically made of high-temperature and oxidation-resistant materials to ensure long-term stability and safety. The heating coating 7 includes graphene and a ceramic-encapsulated outer shell. The ceramic provides insulation and low thermal resistance, effectively protecting the graphene and ensuring the normal operation of the heating coating 7. During use, the fan blades 6 with the heating coating 7 not only enhance heating efficiency but also optimize airflow, resulting in more even, energy-efficient, and safer heating.

[0037] In some embodiments, such as Figure 1 and Figure 5As shown, slip ring 5 is a through-hole conductive slip ring, which mainly consists of a conductive ring 51 connected by a brush 50 and a housing 52. The through-hole conductive slip ring is used to realize the continuous transmission of current and ensure the electrical connection between the motor 1 and the fan blade 6. The through-hole conductive slip ring can ensure the stable transmission of electrical energy during rotation. In one example, the through-hole conductive slip ring is installed between the motor 1 and the fan blade 6. The conductive ring 51 of the through-hole conductive slip ring has a first end 510 and a second end 511. The first end 510 is connected to the rotating shaft 2 of the motor 1, and the second end 511 is connected to the fan blade 6 through a wire. When motor 1 starts, shaft 2 drives conductive ring 51 to rotate, thereby realizing power transmission between motor 1 and the conductive ring 51. The second end 511 is connected to fan blade 6 via a wire, providing a stable power supply so that fan blade 6 can operate normally. The housing 52 has an external power supply terminal, which can easily connect an external power source to the through-hole conductive slip ring. The power supply terminal provides power input from the external power source to the through-hole conductive slip ring. The housing 52 is firmly connected to motor 1, ensuring the through-hole conductive slip ring remains stable during rotation and preventing unstable or disconnected power transmission due to vibration or mechanical deformation. In another example, such as... Figure 7 As shown, motor 1 is a hollow shaft motor, allowing the output shaft of the hollow shaft motor to pass through the entire motor. A fan blade 6 is mounted on one end of the output shaft. A through-hole conductive slip ring is located on the side of the hollow shaft motor away from the fan blade 6. The first end 510 of the conductive ring 51 is rotatably connected to the other end of the output shaft, and the second end 511 of the conductive ring 51 is provided with a wire. In the assembled state, the wire passes through the output shaft and connects to the fan blade 6. The conductive ring 51 is in close contact with the brush 50, and the brush 50 is mounted on the hollow shaft motor. During use, the brush 50 and the conductive ring 51 always maintain contact, thereby achieving a smooth and reliable rotary connection. In another example, as... Figure 8As shown, motor 1 is a hollow shaft motor, allowing the output shaft of the hollow shaft motor to pass through the entire motor. A fan blade 6 is mounted on one end of the output shaft. A through-hole conductive slip ring is located on the side of the hollow shaft motor away from the fan blade 6. The first end 510 of the conductive ring 51 is rotatably connected to the other end of the output shaft. A wire is provided on the second end 511 of the conductive ring 51, passing through the output shaft and connecting to the fan blade 6. The conductive ring 51 is movably connected to the brush 50. Specifically, a telescopic member 8 is provided at the top of the brush 50. A retaining ring 81 and a return spring 82 are provided inside the telescopic member 8. One end of the return spring 82 is connected to the pressure rod 80, and the other end is connected to the brush 50. The pressure rod 80 is movably connected to the brush 50 so that the brush 50 can move closer to or away from the conductive ring 51. When the operator presses the pressure rod 80 toward the conductive ring 51, the return spring 82 is compressed, and the retaining ring 81 engages with the inner wall of the telescopic member 8, so that the brush 50 moves closer to and contacts the conductive ring 51. This ensures that the signal and energy transmission is efficient and stable when the fan blade 6 rotates. When the operator presses the pressure rod 80 again, the return spring 82 releases the pressure, so that the retaining ring 81 disengages from the telescopic member 8, and the brush 50 moves away from the conductive ring 51. The movable connection between the conductive ring 51 and the brush 50 enables the air convection device to switch between hot and cold air.

[0038] In some embodiments, the number of fan blades 6 is adapted as needed. In one example, five fan blades 6 are provided, and the five fan blades 6 are arranged at circumferential intervals along the rotating shaft 2, which makes the airflow more uniform during the operation of the device and avoids the situation where the local airflow is too strong or too weak. Through the coordinated action of the five fan blades 6, the air can be pushed more effectively, ensuring that the hot air is evenly distributed in the space and achieving a better heating effect.

[0039] The working principle of the auxiliary heating air convection device in this application is as follows:

[0040] like Figures 1 to 6 As shown, firstly, the drive motor 1 and ventilation device 4 are activated. The shaft 2 of the motor 1 starts to rotate and transmits power to the fan blade 6 through the conductive ring 51 of the slip ring 5. This achieves the transfer of electrical energy between the motor 1 and the fan blade 6. The conductive ring 51 rotates with the fan blade 6, and the electrical energy is continuously transferred to the fan blade 6 through the brush 50, thereby maintaining the stable operation of the device and ensuring that the airflow is evenly distributed. At the same time, the axial flow motor 420 in the heating device 42 draws external air into the ventilation duct 41. When the air passes through the ventilation duct 41, it flows through the heating element 421 and gradually increases in temperature after being heated. The heated air then continues to move along the flow direction of the ventilation duct 41 and is finally discharged from the air outlet 410. The hot air is then transported to the required area by the rotation of the fan blade 6, thereby achieving air heating and circulation.
