[0033] 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.

[0034] like Figures 1 to 7 As shown, this utility model discloses a far-infrared fan for both heating and cooling, including a drive unit 1, fan blades 2, a protective assembly 3, and an auxiliary heating assembly 4. The drive unit 1 provides rotational force. In this application, the drive unit 1 is an electric motor, and the output end of the electric motor is connected to a rotating shaft 10. The rotating shaft 10 extends along the central axis of the fan to drive the fan blades 2 to rotate, thereby generating airflow. Multiple fan blades 2 are installed at the end of the rotating shaft 10 away from the drive unit 1, and the multiple fan blades 2 are arranged circumferentially along the rotating shaft 10 (e.g.,...). Figure 1The blades 2 are arranged at intervals in the direction A shown in the diagram. The shape of the blades 2 can be a leaf-shaped structure, a sickle-shaped structure, a spiral structure, etc., and can be adapted as needed.

[0035] In one example, such as Figure 2 As shown, the fan blade 2 has a leaf-shaped structure. The middle part of the fan blade 2 is rectangular, and the two ends are arc-shaped. It is installed at an angle on the rotating shaft 10 so that there is a preset angle between the central axis of the fan blade 2 and the central axis of the rotating shaft 10. The preset angle can be between 5° and 45°. During use, it can effectively reduce noise and optimize the airflow path, reduce eddies and resistance, thereby improving efficiency. It should be noted that there can be three, four, five, six, etc., which can be adapted according to the needs. This application does not impose too many restrictions on this.

[0036] Continue to refer to Figures 1 to 7 The protective component 3 has a hollow structure and is fitted onto the rotating shaft 10, covering the working area of ​​the fan blades 2. This effectively prevents user contact and the entry of foreign objects into the working area. The hollow shape can be square, round, or irregular, allowing the user to easily observe the status of the working area and the flow of cold air being heated during operation. If any abnormality occurs, the user can immediately stop use or perform inspection and repair, thus improving the safety and reliability of the fan. The auxiliary heating component 4 is located between the protective component 3 and the fan blades 2. The auxiliary heating component 4 heats the passing air. It includes a first cover 5 and a second cover 6 coaxially arranged. Both the first cover 5 and the second cover 6 can be hemispherical, cylindrical, or horn-shaped, adaptable to different requirements. In one example, for instance... Figure 1As shown, both the first cover 5 and the second cover 6 are hemispherical shells. The two hemispherical shells are combined to form the auxiliary heating assembly 4, which can effectively contain heat. In the assembled state, it adapts to the fan blade 2, so that the heat can be concentrated in a large space while protecting the fan blade 2 from external damage. The first cover 5 has an air inlet 51 and a first connecting port 52. The air inlet 51 and the first connecting port 52 are coaxially arranged. The shape of the air inlet 51 and the first connecting port 52 can be adapted as needed, and can be circular, square, etc. For example, the air inlet 51 and the first connecting port All 52 are circular, which can smoothly gather the airflow through the air inlet 51 to the area around the fan blade 2 for heating treatment, and then transport it to the required area by the fan blade 2. The diameter of the first connection port 52 is larger than the diameter of the air inlet 51, thereby ensuring a firm connection. The second cover 6 has an air outlet 61 and a second connection port 62. It should be noted that the shapes of the air outlet 61 and the second connection port 62 match the air inlet 51 and the first connection port 52 mentioned above. This will not be elaborated further in this application. The first cover 5 is connected to the second cover 6 through the first connection port 52 and the second connection port 62.

[0037] During use, airflow enters the auxiliary heating component 4 through the air inlet 51 and is heated by the auxiliary heating component. The resulting hot air is then delivered to the required area through the air outlet 61 by the rotating fan blades 2. Traditional auxiliary heating fans use a power slip ring power supply mechanism, which can easily cause safety hazards and noise due to the friction between the slip ring and carbon brush during operation, thus affecting the service life. In this application, the auxiliary heating component 4 is placed between the protective component 3 and the fan blades 2. When the fan is running, the shaft 10 on the fan only drives the fan blades 2 to rotate, while the auxiliary heating component 4 and the protective component 3 remain fixed. The auxiliary heating component 4 provides heat, thereby heating the airflow. The entire fan can save costs and extend its service life.

[0038] Preferred, such as Figures 1 to 3 As shown, the protective component 3 has a connecting hole 31 on one side. The protective component 3 is sleeved on the rotating shaft 10 through the connecting hole 31, and is matched with the rotating shaft 10 with a gap. That is, the connecting hole 31 is circular in shape so that the protective component 3 can be connected to the rotating shaft 10 through the connecting hole 31. For example, the protective component 3 is connected to the rotating shaft 10 through a rotating part. During rotation, the rotating shaft 10 drives the fan blade 2 to rotate, and the protective component 3 remains in a fixed state. For another example, the protective component 3 is fixedly connected to the fixed end of the drive part 1 to ensure that the state of the protective component 3 remains unchanged during the rotation of the rotating shaft 10, thereby effectively protecting the fan blade 2, the rotating shaft 10 and the auxiliary heating component 4, and preventing the components from loosening or falling off due to vibration or airflow during the operation of the electric fan, thereby improving the stability and safety of the electric fan.

[0039] The auxiliary heating component 4 has a spherical hollow structure. The spherical hollow structure of the auxiliary heating component 4 is axially connected to facilitate air circulation. The auxiliary heating component 4 is connected to the protective component 3 through connectors (such as bayonet, fastener or threaded connector, etc.) to ensure a compact structure and facilitate subsequent maintenance or cleaning. In the assembled state, the first cover 5 and the second cover 6 are coaxially connected to form an air heating channel. That is, when the airflow passes through the auxiliary heating component 4, the first cover 5 and the second cover 6 generate heat to heat the airflow. Then the hot airflow is delivered to the required area through the air outlet 61.

[0040] Preferred, such as Figures 1 to 4 As shown, the protective component 3 consists of multiple rays 32, which radiate outwards along the circumference of the rotation axis 10 (e.g., Figure 2 As shown in direction A, the entire structure forms a safety shield that can effectively prevent foreign objects from contacting the fan blades 2 while ensuring smooth airflow. Specifically, multiple rays 32 are arc-shaped, and the first ends 320 of the multiple rays 32 are connected and overlapped. The second ends 321 of the multiple rays 32 are connected to form a connection hole 31, thereby effectively protecting the fan blades 2 and the auxiliary heating component 4 and preventing users from being injured by contact and foreign objects from entering and causing safety problems.

[0041] Preferably, the connection method between the first connection port 52 and the second connection port 62 can be adapted as needed. For example, the first connection port 52 and the second connection port 62 can be an integral structure to ensure that there is no gap between the first cover 5 and the second cover 6, and that it has strong rigidity and support to achieve uniform heating and practicality. Alternatively, the first connection port 52 and the second connection port 62 can be detachably connected to facilitate user inspection and maintenance, and to allow for subsequent disassembly and installation to ensure that the auxiliary heating component 4 works normally.

[0042] Preferably, the auxiliary heating component 4 is provided with multiple through holes, which are breathable to ensure that the heat generated by the auxiliary heating component 4 is evenly distributed to the external space, while avoiding excessively high internal temperature of the auxiliary heating component 4. In one example, such as... Figure 2 and Figure 5 As shown, the surface of the first cover 5 has a plurality of first through holes 53, and the first through holes 53 are along the circumference of the first cover 5 (e.g., Figure 2 As shown in the diagram (direction A), the auxiliary heating component 4 generates heat to heat the airflow when it enters. Once the preset temperature is reached, excess heat is dispersed into the external environment through the first through-hole 53. The heated airflow is then output from the outlet 61. In another example, as shown... Figure 2 and Figure 6 As shown, the surface of the second cover 6 has a plurality of second through holes 63, and the second through holes 63 are along the circumference of the second cover 6 (e.g., Figure 2As shown in the A direction, the auxiliary heating component 4 generates heat to heat the airflow when the airflow enters the auxiliary heating component 4. When the preset temperature is reached, the excess heat is dispersed into the external environment through the second through hole 63. The heated airflow is output from the air outlet 61 to achieve heat balance.

[0043] Preferred, such as Figures 5 to 6 As shown, the first through hole 53 or the second through hole 63 has a circular structure. For example, the first through hole 53 has a circular structure, which can smoothly output airflow and prevent heat from accumulating in the auxiliary heating component 4 for a long time, thus preventing damage to the fan blade 2. For another example, the second through hole 63 has a circular structure, which can smoothly output airflow and effectively ensure that the temperature inside the auxiliary heating component 4 is maintained at a preset state, thereby realizing hot air output.

[0044] For the best options, please continue to refer to them. Figures 1 to 5 The auxiliary heating component 4 is provided with a first heating layer 7, which is used to provide a heat source to enhance the heating effect. The first heating layer 7 is fixed to the surface of the first cover 5 and the second cover 6. For example, the first heating layer 7 is located on the inner side wall of the first cover 5 and the second cover 6, so that the heat is transferred more directly to the internal space of the auxiliary heating component 4, thereby improving the heating efficiency. Alternatively, the first heating layer 7 is located on the outer side wall of the first cover 5 and the second cover 6, so as to achieve the heating effect through indirect conduction, and may also help to achieve the external heat preservation effect.

[0045] Preferably, the first heating layer 7 is any one of an electronic heating element, a ceramic heating element, a graphite coating, or a graphene coating. In one example, the first heating layer 7 is an electronic heating element, which has advantages such as high stability and fast response speed. The heating element's temperature is controlled by a controller. The heating end of the electronic heating element is fixed to the first cover 5 and the second cover 6. During use, the heat output of the electronic heating element is controlled to adapt the blown hot air to different environments. In another example, the first heating layer 7 is a graphene coating. Graphene, as a novel nanomaterial, has excellent thermal conductivity, high electrothermal conversion efficiency, good flexibility, and energy-saving and environmentally friendly properties. It can achieve a more uniform and efficient heat distribution, thereby improving the overall performance and service life of the first heating layer 7 and meeting the dual requirements of electric fans for heat source stability and energy efficiency. In addition, the graphene coating surface is also equipped with far-infrared radiation heating. When the electric fan heats up to 200-400℃, the far-infrared wavelength released is stable at 6-14μm, with a peak of about 9μm, which is highly matched with the human body's own radiation wavelength (9.35μm). This can induce a resonance effect, promote energy absorption, and thus have benefits such as improving blood circulation and relieving joint pain. At the same time, it can also disinfect the surrounding environment, effectively kill bacteria and viruses, and ensure the switching and applicability of the electric fan's three different effects: cold air, hot air, and far-infrared radiation.

[0046] Preferred, such as Figure 1 and Figure 7 As shown, a louver 8 composed of multiple blades 81 is also installed at the air outlet 61. The louver 8 effectively controls the airflow speed and direction, thereby improving the overall heating or ventilation efficiency. The multiple blades 81 are arranged along the horizontal direction of the air outlet 61 (e.g., ...). Figure 7 The air ducts are arranged sequentially in the x-direction (shown in the figure) or vertical direction (not shown in the figure), and are rotatably connected to the first cover 5 through a rotating shaft or hinge structure. The rotation angle can be adjusted according to actual usage needs, thereby flexibly controlling the air output direction and air volume to adapt to different usage environment conditions.

[0047] Preferably, each blade 81 has a second heating layer 9 on its surface. The second heating layer 9 can be an electronic sheet, ceramic, or graphene, etc., and can be adapted as needed. When the blade 81 rotates, the second heating layer 9 evenly transfers heat to every area of ​​the airflow, thereby ensuring that the airflow temperature remains within the set range. In addition, due to the rotation of the blade 81, the second heating layer 9 continuously releases heat as air passes through, ensuring that the airflow passing through the louvers 8 always has a stable temperature and a comfortable airflow.

[0048] The working principle of the far-infrared fan for both heating and cooling in this application is as follows:

[0049] like Figures 1 to 7 As shown, the fan blades 2 are first driven to rotate by the drive unit 1 to form an airflow. When the user needs hot air, the first heating layer 7 on the auxiliary heating component 4 is activated. The first heating layer 7 provides additional heat, and the excess heat can be dissipated from the first through hole 53 or the second through hole 63. At the same time, the rotating fan blades 2 can generate hot air through the heat generated and blow the hot air to the required area through the air outlet 61. During this process, the user can rotate the louvers 8 at the air outlet 61 as needed to change the air direction and air force, thereby achieving the dual functions of heating and air supply. Alternatively, when the fan blades 2 collect external air through the air inlet 51 and deliver it to the air outlet 61, the surface of the louvers 8 on the air outlet 61 has a second heating layer 9. The heat generated by the second heating layer 9 is transferred to the passing airflow, so that the output air not only has strong fluidity but also has a significant warming effect, thereby improving the flexibility and convenience of the user.

[0050] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
