The main body has a first side and a second side oppositely arranged in a first direction. The main body has a non-air outlet area and an air outlet area on the first side, and an air outlet is arranged on the air outlet area and surrounds the periphery of the non-air outlet area. The main body has an air inlet on the second side. The air supply assembly is arranged in the main body and is configured to drive airflow from the air inlet to the air outlet. The air supply device re-designs the positional relationship between the air outlet area and the non-air outlet area, so that the air outlet surrounds the periphery of the non-air outlet area instead of being arranged vertically. In this way, the overall air supply airflow of the air supply device is more divergent, the concentration is lower, and in the case of the same air outlet area, the range covered by the air outlet is larger. When the air supply device is running, it can continuously suck air from the back and blow it out in a more dispersed form from the front.

Description

Technical Field

[0001] This application relates to the field of heating equipment technology, and in particular to an air supply device and a warm air blower. Background Technology

[0002] The simulated flame heater is divided into a visual flame section and a heating section. These two sections are laid out independently. The heating section forms the air outlet and is used to deliver warm air outwards. The visual flame section and the heating section are generally arranged vertically, with the heating section on top and the visual flame section below, or vice versa. The common shapes are square or columnar, which are what the industry commonly refers to as tabletop or tower heaters.

[0003] This layout results in a narrow heating range and uneven heat distribution in practical use. Specifically, in an indoor environment, the warm air cannot effectively cover the entire space, causing areas near the air outlet to overheat while areas further away remain cold. Users are forced to frequently move their bodies or move their mobile devices to seek comfort, making the user experience extremely inconvenient. More seriously, excessive heat concentration can lead to the risk of localized high temperatures. For example, when the device is near furniture or people, it can easily cause burning discomfort or even safety hazards, especially in households with children or the elderly. Utility Model Content

[0004] Therefore, it is necessary to provide an air supply device and heater that can expand the coverage of warm air and make the heat more dispersed, in order to address the above problems.

[0005] An air supply device, the air supply device comprising:

[0006] The main body has a first side and a second side disposed opposite to each other in a first direction; the main body has a non-air outlet area and an air outlet area on the first side, and an air outlet is provided in the air outlet area, the air outlet being disposed around the periphery of the non-air outlet area; the main body has an air inlet on the second side; and

[0007] An air supply assembly is disposed within the main body and configured to drive airflow from the air inlet to the air outlet.

[0008] The aforementioned air supply device redesigns the positional relationship between the air outlet area and the non-air outlet area, placing the air outlets around the perimeter of the non-air outlet area instead of vertically distributing them. This allows the airflow to exit from the perimeter of the non-air outlet area. Compared to the vertically distributed design, the overall airflow of this air supply device is more dispersed, less concentrated, and covers a larger area for the same air outlet area. During operation, the air supply device continuously draws in air from the back and blows it out from the front in a more dispersed manner. Specifically, the air outlets are annular and arranged around the non-air outlet area.

[0009] In one embodiment, the air supply assembly includes an air duct structure and an air supply component;

[0010] The air duct structure has an air guide inlet and an air guide outlet, the air guide inlet is connected to the air inlet, and the air guide outlet is connected to the air outlet; the air supply component is configured to drive airflow from the air guide inlet to the air guide outlet.

[0011] In this way, the air supply component is used to drive the airflow along the duct structure to form the air supply airflow, and guided by the duct structure, the air supply airflow is finally directed to the air outlet and blown out.

[0012] In one embodiment, the air guide inlet is provided corresponding to the air inlet;

[0013] The air supply component includes a centrifugal impeller, which is disposed within the air duct structure, with the air inlet end of the centrifugal impeller facing the air guide inlet.

[0014] In this way, the centrifugal impeller can concentrate the airflow drawn in from the air inlet and blow it out from its own periphery in a diffused manner, which can better adapt to the air outlet pattern.

[0015] In one embodiment, the inner surface of the duct structure includes an arc-shaped guide surface located on the radial circumference of the centrifugal impeller and arranged around the centrifugal impeller, and used to guide airflow to the air outlet.

[0016] In this way, the airflow generated by the centrifugal impeller can better form a ring airflow under the guidance of the arc-shaped guide surface, and can better adapt to the shape of the air outlet, resulting in less wind power loss.

[0017] In one embodiment, the air supply device further includes a heating element disposed at the air outlet; along the first direction, the projection of the heating element at least partially overlaps with the projection of the air outlet.

[0018] Thus, the air supply device is a heater, capable of heating the airflow at the air outlet through a heating element, forming warm air that is blown outwards. Thanks to the design of the air outlet, the area available for installing the heating element is increased, resulting in a corresponding increase in the heating area.

[0019] In one embodiment, the air supply device includes a mounting bracket having an assembly groove located on the side facing the air outlet and communicating with the air outlet, and the heating element is disposed in the assembly groove.

[0020] In this way, the airflow can be blown into the assembly slot, heated by the heating element inside, and then blown out from the air outlet.

[0021] In one embodiment, the heating element is continuously arranged along the length extension direction of the assembly groove.

[0022] In this way, the heating elements are arranged continuously without any breaks, which can more fully fill the assembly slot, thereby increasing the heating area of ​​the airflow and improving the heating effect.

[0023] In one embodiment, the air supply device further includes a heating element disposed at the air inlet; along the first direction, the projection of the heating element at least partially overlaps with the projection of the air inlet.

[0024] In this way, the airflow drawn in from the air inlet is effectively heated by the heating element, and then fully mixed during the subsequent flow process to even out the heat before being blown out through the air outlet.

[0025] In one embodiment, the air supply device further includes a front panel disposed in the non-air outlet area, and the air duct structure is spaced apart from the front panel to form a receiving cavity.

[0026] In this way, the front panel and the air duct structure behind it together define a cavity, which can be used to assemble other components, thus improving the space utilization rate inside the air supply device.

[0027] In one embodiment, the front panel is a transparent structure; the air supply device further includes a charcoal fire-simulating component disposed in the receiving cavity.

[0028] Thus, the heater is a flame-simulating heater, which can utilize the space in the non-air outlet area to accommodate the charcoal fire-simulating components, and the warm air can be blown out around the charcoal fire-simulating components.

[0029] In one embodiment, the simulated charcoal fire component includes a simulated charcoal fire structure, a semi-transparent plate, a light-emitting element, and a reflective element;

[0030] The light-emitting element is configured to illuminate the simulated charcoal fire structure and the reflector; the semi-transparent plate is at least partially located above the simulated charcoal fire structure, and the reflector is configured to reflect light toward the semi-transparent plate;

[0031] The reflector is configured with a tapered width at at least one end in the height direction of the air supply device; and / or, the lower end face of the semi-transparent plate is a wavy surface.

[0032] Thus, when the light-emitting components are activated, some light shines from the front onto the simulated charcoal structure, allowing the charcoal fire effect to be seen from the front of the machine. Other light shines from above onto the reflector surface, which reflects the light onto the rear surface of the semi-transparent plate, positioned directly above the simulated charcoal fire to create the visual effect of flames. The tapered reflector creates a blurred, gradual edge to the reflected light spot, simulating the smooth transition of a flame's edge. The scattered light from the lower edge of the semi-transparent plate forms a staggered transition of light and shadow, simulating the irregular movement of the flame's base and enhancing dynamic realism.

[0033] In one embodiment, the air outlet is annular and arranged around the non-air outlet area.

[0034] In this way, the airflow from the air outlet is more evenly distributed in space, and the air outlets are located on the outer periphery of the non-air outlet area, which covers a larger area compared to concentrated placement.

[0035] A space heater includes the aforementioned air supply device.

[0036] The aforementioned space heater has its air outlets positioned around the perimeter of the non-outlet areas, rather than vertically. This allows the airflow to exit from the perimeter of these non-outlet areas. Compared to a vertically distributed outlet design, the overall airflow is more dispersed and less concentrated, and the outlets cover a larger area for the same surface area. When running, the heater continuously draws in air from the back and blows it out from the front in a more dispersed manner. With separate air intake and exhaust at the front and back, there is less interference between the two, resulting in more dispersed airflow, lower heat concentration, and a more comfortable heating effect.

[0053] Please see Figures 1 to 4 An embodiment of this application provides an air supply device 100, including a main body 10 and an air supply assembly 20. The main body 10 has an air supply component 20 in a first direction (e.g., Figure 2 The main body 10 has a first side 11 and a second side 12 arranged opposite each other in the X direction (as shown). The main body 10 has a non-exhaust area 111 and an exhaust area 112 on the first side 11, and an exhaust port 113 is provided in the exhaust area 112, the exhaust port 113 surrounding the periphery of the non-exhaust area 111. The main body 10 has an air inlet 121 on the second side 12. An air supply assembly 20 is disposed within the main body 10 and configured to drive airflow from the air inlet 121 to the air outlet 113.

[0054] In one embodiment, the air supply device 100 can be used as a heater. In other embodiments, the air supply device 100 can also be an air purifier, a fan, etc., and is not specifically limited here.

[0055] Specifically, the first direction is the front-to-back direction of the main body 10. The first side 11 of the main body 10 can correspond to the front of the air supply device 100, and the second side 12 can correspond to the back of the air supply device 100. Therefore, when the air supply device 100 is working, it draws in airflow from the air inlet 121 on the back and blows it out from the air outlet 113 on the front, forming a supply airflow (such as...). Figure 2 (As indicated by the middle arrow).

[0056] The air outlet 113 can be a single unit or composed of several openings, as long as it is positioned around the non-air outlet area 111. The airflow from the air supply device 100 is blown out from the air outlet 113, that is, blown out around the non-air outlet area 111.

[0057] The non-air-ventilated area 111 can be used as a visual effect area, a control area, or a blank area. The visual effect area can display visual effects such as simulated charcoal fire, the blank area simply has a panel structure set within it, and the control area can have operation buttons, parameter displays, etc. set within it.

[0058] The aforementioned air supply device 100 redesigns the positional relationship between the air outlet area 112 and the non-air outlet area 111, so that the air outlet 113 is positioned around the periphery of the non-air outlet area 111, rather than being distributed vertically. In this way, the airflow can be blown out from the periphery of the non-air outlet area 111. Compared to the vertically distributed design, the overall airflow of the air supply device 100 is more dispersed and less concentrated, and with the same air outlet area, the area covered by the air outlet 113 is larger. When the air supply device 100 is operating, it can continuously draw in air from the back and blow it out from the front in a more dispersed manner. With air outlets and inlets at the front and back of the air supply device 100 respectively, the degree of mutual interference is reduced, and the airflow is more dispersed. When blowing warm air, the heat concentration is lower, resulting in a more comfortable heating effect.

[0059] Specifically, the air outlet 113 is ring-shaped and is arranged around the non-air outlet area 111.

[0060] Understandably, the non-air outlet area 111 is generally circular, and the air outlet 113 is an annular ring surrounding the non-air outlet area 111, with both arranged concentrically. In some other embodiments, the air outlet 113 may also be part of an annular ring, i.e., a fan ring, and the curvature may be, but is not limited to, π, 4π / 3, 5π / 3, 7π / 4, etc.

[0061] In this way, the airflow blown out by the air outlet 113 is more evenly distributed in space, and the air outlet 113 is distributed on the outer periphery of the non-air outlet area 111, which is larger in area than if it were concentrated in one place.

[0062] More specifically, the main body 10 includes a mounting bracket 13. The mounting bracket 13 can serve as a mounting base for other structures, and the mounting bracket 13 can be generally annular. The mounting bracket 13 can form an air outlet 113, and it has a hollow area and a non-air outlet area 111 corresponding to the main body 10.

[0063] In addition, the main body 10 also includes a housing 14, a rear housing 15, and a mesh cover 16. The housing 14 has a ring-shaped design and is fitted over the outside of the mounting bracket 13. A display panel 17 is mounted on the top of the housing 14, and the housing 14 has a display and operation area corresponding to the display panel 17. The mesh cover 16 covers the air outlet 113 to prevent accidents caused by users or external structures extending into the air outlet 113. The rear housing 15 is connected to the back side of the mounting bracket 13 and can form an air inlet mesh in its middle as an air inlet 121.

[0064] In some embodiments, the main body 10 further includes a heating element 18. Understandably, the air supply device 100 is used for a heater and may be the head of the heater, and can heat the air supply airflow at the air outlet 113 through the heating element 18 to form warm air that is blown outward.

[0065] In some embodiments, the heating element 18 is disposed at the air outlet 113. Along a first direction, the projection of the heating element 18 at least partially coincides with the projection of the air outlet 113.

[0066] The shape of the heating element 18 can match the air outlet 113. Specifically, the heating element 18 can be generally ring-shaped.

[0067] Along the first direction, the projection of the heating element 18 can completely overlap with the projection of the air outlet 113, partially overlap, or the projection of the heating element 18 can be within the projection range of the air outlet 113. It is only necessary to ensure that the airflow can pass through the heating element 18 and be heated by it.

[0068] In related technologies, space heaters generally use PTC heating elements. These heating elements have a rectangular cross-section, and their heating area is related to power and size. Higher power and larger size result in a larger heating area, but the heating zone is concentrated, resulting in a smaller area. For example, with a power rating of 2000W, a relatively large PTC heating element in the industry has a length * width = 225mm * 52mm, and its area is 11700mm². However, if the heating element 18 is designed and installed at the annular air outlet 113, and the non-outlet area 111 is not heated, taking an inner diameter R1 of 154mm and an outer diameter R2 of 181mm as an example, its heating area = π * (R1...) 2 -R2 2 )=3.14*(181*181-154*154)=28401.3mm 2 The heating area is much larger than that of a rectangular PTC heating element.

[0069] Thus, thanks to the design of the air outlet 113, the area available for installing the heating element 18 is increased, and the heating area is correspondingly improved.

[0070] In some embodiments, the mounting bracket 13 also has a mounting groove 131, which connects to the air outlet 113, and the heating element 18 is disposed in the mounting groove 131. Understandably, the mounting groove 131 and the heating element 18 are shaped to match each other.

[0071] In this way, the airflow can be blown into the assembly slot 131, heated by the heating element 18 inside, and then blown out from the air outlet 113.

[0072] Furthermore, the first end of the mounting bracket 13 in the first direction can be formed as an air outlet 113. The mesh cover 16 is annular and is provided to cover the air outlet 113 of the mounting bracket 13 to prevent the user from touching the heating element 18.

[0073] Furthermore, the heating element 18 is continuously arranged along the length extension direction of the assembly groove 131. Specifically, the dimensions of the heating element 18 in its length extension direction are substantially the same as the dimensions of the assembly groove 131 in its length extension direction.

[0074] In this way, the heating element 18 is continuously arranged without any breaks, which can more fully fill the assembly slot 131, thereby increasing its heating area for the airflow and improving the heating effect.

[0075] In some embodiments, the air supply assembly 20 includes an air duct structure 21 and an air supply element 22. The air duct structure 21 has an air inlet 211 and an air outlet 212, the air inlet 211 being connected to an air inlet 121 and the air outlet 212 being connected to an air outlet 113. The air supply element 22 is configured to drive airflow from the air inlet 211 to the air outlet 212.

[0076] Understandably, the air duct structure 21 can guide the airflow generated by the air supply component 22 to the air outlet 113. Specifically, the air outlet 212 is annular and is provided corresponding to the air outlet 113, or the air outlet 212 serves as the air outlet 113.

[0077] The air supply component 22 may include an impeller and a main motor 222. The main motor 222 is connected to the impeller and is used to drive the impeller to rotate. The impeller may be, but is not limited to, a centrifugal impeller 221, an axial flow impeller, a cross-flow impeller, etc., and is not specifically limited here.

[0078] Thus, the air supply component 22 is used to drive the airflow to flow along the air duct structure 21 to form a supply airflow, and guided by the air duct structure 21, the supply airflow is finally directed to the air outlet 113 and blown out.

[0079] Furthermore, the air inlet 211 is provided corresponding to the air inlet 121. The air supply component 22 includes a centrifugal impeller 221, which is located inside the air duct structure 21, with the air inlet end of the centrifugal impeller 221 facing the air inlet 211.

[0080] When the centrifugal impeller 221 rotates, it can form a low pressure at its air inlet end, drawing gas into the air duct structure 21 through the air inlet 121 and the air guide inlet 211, and then forming a high pressure on the periphery, forming a supply airflow along the air duct structure 21.

[0081] In this way, the centrifugal impeller 221 can concentrate the airflow drawn in from the air inlet 121 and blow it out from its own periphery in a diffused manner, which can better adapt to the air outlet 113.

[0082] Furthermore, the inner surface of the duct structure 21 includes an arc-shaped guide surface 213, which is located on the radial side of the centrifugal impeller 221 and is arranged around the centrifugal impeller 221, and is used to guide the airflow to the guide outlet 212.

[0083] Specifically, the centrifugal impeller 221 can be axially arranged along a first direction, and one end of it in the axial direction is formed as an air inlet.

[0084] The arc-shaped guide surface 213 is recessed, and the angle between the tangent of the arc-shaped guide surface 213 at one end of the air outlet 212 and the first direction is less than 60°.

[0085] The centrifugal impeller 221 rotates to generate a supply airflow that generally flows radially. After flowing toward the arc-shaped guide surface 213, the supply airflow is guided by the arc-shaped guide surface 213 to gradually change its angle so as to flow toward the air outlet 113.

[0086] In this way, the airflow generated by the centrifugal impeller 221 can better form an annular airflow under the guidance of the arc-shaped guide surface 213, and can better adapt to the shape of the air outlet 113, resulting in less wind power loss.

[0087] In some embodiments, the assembly slot 131 is located on the orientation of the air outlet 212.

[0088] Understandably, the second end of the mounting bracket 13 in the first direction is formed as an air inlet, which is connected to the air outlet 212. The mounting groove 131 is specifically located between the air outlet 212 and the air outlet 113.

[0089] Thus, the airflow blown out of the air outlet 212 is blown into the assembly groove 131, and after being heated by the heating element 18 in the assembly groove 131, it is blown out from the air outlet 113 in the form of warm air.

[0090] Specifically, the air duct structure 21 includes a front air duct 214 and a rear air duct 215, which are arranged sequentially along a first direction. A centrifugal impeller 221 is located between the front air duct 214 and the rear air duct 215. The outer periphery of the front air duct 214 and the rear air duct 215 are both bent forward and separated from each other to form an air guide outlet 212. The air guide inlet 211 and the arc-shaped guide surface 213 are located on the rear air duct 215.

[0091] Please see Figure 8 In another embodiment, the heating element 18 is disposed at the air inlet 121. Along the first direction, the projection of the heating element 18 at least partially overlaps with the projection of the air inlet 121.

[0092] The outer contour of the heating element 18 can match the air inlet 121. Specifically, the air inlet 121 can be circular, and the heating element 18 can be generally annular or circular, with its outer diameter being roughly the same as the outer diameter of the air inlet 121.

[0093] Thus, the airflow drawn in from the air inlet 121 is effectively heated by the heating element 18, and then fully mixed during the subsequent flow process. After the heat is evenly distributed, it is blown out through the air outlet 113.

[0094] Furthermore, the heating element 18 is disposed between the air inlet 121 and the air inlet end of the air supply component 22, and is positioned facing upwards from the air inlet end of the air supply component 22. Specifically, the air supply component 22 can be an axial flow fan, and the heating element 18 can be located between the air inlet 121 and the air guide inlet 211.

[0095] Thus, the airflow drawn in from the air inlet 121 can be effectively heated by the heating element 18, then flow through the air supply element 22 and be guided by the air duct structure 21, and finally be blown out to the air outlet 113.

[0096] In some embodiments, the main body 10 further includes a front panel 19, which is disposed in a non-air outlet area 111, and the air duct structure 21 is spaced apart from the front panel 19 to form a receiving cavity 191.

[0097] The front panel 19 is located in the hollow part of the mounting bracket 13, and the air supply device 100 includes the outer surface of the front panel 19 on the surface of the first side 11.

[0098] Thus, the front panel 19 and the air duct structure 21 located behind it together define a receiving cavity 191, which can be used to assemble other components, such as the main motor 222, which helps to improve the space utilization inside the air supply device 100.

[0099] Furthermore, the front panel 19 is a transparent structure. The main body 10 also includes a charcoal-fire-like component 101, which is disposed in the receiving cavity 191.

[0100] Understandably, the non-airflow area 111 is the visual area. Light can pass through the front panel 19 in a straight line with almost no scattering. The internal structure has minimal impact on the appearance, and the details of objects behind it can be clearly seen. Users can observe the simulated charcoal fire component 101 behind it through the front panel 19. Specifically, to achieve good light transmission, the light transmittance of the front panel 19 can exceed 90%.

[0101] In this way, the air supply device 100 can present a flame-like effect, and can use the space of the non-air outlet area 111 to accommodate the charcoal fire-like component 101, and warm air can be blown out around the charcoal fire-like component 101.

[0102] In some embodiments, the simulated charcoal fire component 101 includes a simulated charcoal fire structure 1011, a semi-transparent plate 1012, a light-emitting element 1013, and a reflective element 1014.

[0103] The light-emitting element 1013 is configured to illuminate the simulated charcoal structure 1011 and the reflector 1014. The semi-transparent plate 1012 is at least partially located above the simulated charcoal structure 1011, and the reflector 1014 is configured to reflect light onto the semi-transparent plate 1012.

[0104] Specifically, the light-emitting element 1013 can be a lamp panel, and the reflective element 1014 can be a reflector. The lamp panel is located between the semi-transparent plate 1012 and the reflector, and the lamp panel provides a light source for illuminating the simulated charcoal fire structure 1011 and the reflector.

[0105] The semi-transparent panel 1012 is semi-transparent, and light is diffusely reflected or scattered on it, only revealing a blurry outline and failing to clearly display details of objects on the back. When light shines on the semi-transparent panel 1012, it can provide a visual effect similar to firelight. Specifically, to achieve a good semi-transparent effect, the light transmittance of the semi-transparent panel 1012 is between 10% and 90%, and can be specifically 10%, 20%, 30%, 50%, 70%, etc.

[0106] Furthermore, at least one end of the reflector 1014 in the height direction of the air supply device 100 is configured to have a tapered width.

[0107] Understandably, in the height direction of the air supply device 100, at least one end of the reflector 1014 gradually decreases in width along the direction away from its own center. The width direction of the reflector 1014 is perpendicular to the height direction of the air supply device 100. In other words, at least one end of the reflector 1014 is a pointed tip, and the tip may be rounded.

[0108] The simulated charcoal fire component 101 may include at least two reflectors 1014, and all reflectors 1014 may be arranged sequentially along the width direction.

[0109] Thus, when the light-emitting component 1013 is turned on, some light shines from the front onto the simulated charcoal structure 1011, allowing the charcoal fire effect to be seen from the front of the entire machine. Some light shines from above onto the surface of the reflector 1014, which reflects light and reflects it onto the rear surface of the semi-transparent plate 1012, which is positioned just above the simulated charcoal fire to create the visual effect of flames. The tapered reflector 1014 makes the edge of the reflected light spot appear blurred and gradually changes, simulating the soft transition of the flame edge.

[0110] Furthermore, the lower end face of the semi-permeable plate 1012 is a wavy surface.

[0111] In this way, the scattered light from the lower edge of the semi-transparent plate 1012 creates staggered light and shadow transitions, simulating the irregular jumping at the bottom of the flame and enhancing the dynamic realism.

[0112] Specifically, the simulated charcoal fire assembly 101 also includes a drive mechanism 1015, which is connected to the reflector 1014 and configured to drive the reflector 1014. The drive mechanism 1015 may include a rotating shaft 1016 and a drive motor 1017, which is connected to the rotating shaft 1016. All the reflectors are mounted on the rotating shaft 1016.

[0113] Thus, because the reflector is continuously rotated by the drive motor 1017, the problem of fixed reflected light can be overcome. Therefore, the user can vaguely see the light dancing on the semi-transparent panel 1012 from the front, giving the overall effect a visual feeling of flickering flames.

[0114] Please refer to the following: Figures 5 to 7 The aforementioned air supply device 100 includes a main body 10 and an air supply component 20. The main body 10 includes a circular flame part and an annular heating part. The basic working principle of the air supply device 100 is: the air supply component 20 draws air from the back of the main body 10 and blows it out after entering the annular heating part, thereby achieving the effect of annular hot air output. The central part is a circular flame part, which is used to simulate the burning of charcoal.

[0115] The annular heating element includes a mesh cover 16, a mounting bracket 13, a heating element 18, a main board 181, a housing 14, and a display panel 17. The central flame element includes a front panel 19, a simulated charcoal structure 1011, a semi-transparent plate 1012, a light panel as a light source 1013, a reflector as a reflector 1014, and a drive mechanism 1015, which includes a rotating shaft 1016 and a drive motor 1017. The air supply assembly 20 includes a main motor 222, a front air duct 214, a rear air duct 215, and a centrifugal impeller 221.

[0116] Assembly of the annular heating element: The mounting bracket 13, as the main body 10, is annular in design and has an annular receiving cavity 191 around its perimeter; the heating element 18 is also annular in design and can be installed in the annular receiving cavity 191 of the mounting bracket 13; the mesh cover 16 is wrapped around the annular area of ​​the mounting bracket 13, and the mesh of the mesh cover 16 prevents the heating element 18 from being touched by hand; the heating element 18 includes a structural bracket and heating wires mounted on the structural bracket, and a part of the structural bracket is used to mount the main board 181; the outer shell 14 is annular in design, and a display panel 17 is mounted on its top. The outer shell 14 has a display and operation area corresponding to the position of the display panel 17; the outer shell 14 covers the outside of the mounting bracket 13.

[0117] Circular flame assembly: The front panel 19 is installed in the hollow part of the mounting bracket 13 (i.e., in the annular hollow area); the simulated charcoal structure 1011 is fixed together with the semi-transparent plate 1012 and then installed behind the front panel 19. From the front of the whole machine, the simulated charcoal and the semi-transparent plate 1012 behind it can be seen; the drive motor 1017 is connected to the rotating shaft 1016, the reflector is passed through the rotating shaft 1016, and the light panel is set between the semi-transparent plate 1012 and the reflector. The light panel provides a light source for illuminating the simulated charcoal structure 1011 and the reflector. Thus, when the light panel is turned on, some light shines from the front onto the simulated charcoal structure 1011, allowing the charcoal fire effect to be seen from the front of the machine. Some light shines from above onto the reflector surface, which reflects light onto the rear surface of the semi-transparent plate 1012. As the reflector is driven by the motor 1017 to rotate continuously, the light on the semi-transparent plate 1012 can be vaguely seen from the front of the machine, appearing as if it is dancing, which is just above the simulated charcoal fire. The overall effect gives people the visual feeling of flames dancing.

[0118] An air supply assembly 20 is installed behind the circular flame section. The air supply assembly 20 has a main motor 222 and a centrifugal impeller 221 installed in the front air duct 214. A rear air duct 215 is set behind the fan blades. An air inlet mesh is opened on the outer shell 14 behind the rear air duct 215. When the air enters the air duct structure 21 from the air inlet 121, the front air duct 214 and the rear air duct 215 form an annular air guide outlet 212, which corresponds exactly to the air receiving port of the mounting bracket 13. In this way, the air entering the air duct structure 21 is guided to flow through the heating element 18, and then blown out from the front of the whole machine through the air outlet 113 and the mesh cover 16, forming an annular air outlet effect.

[0119] Thus, the main body 10 of the air supply device 100 is designed with a flame display section in the middle, and the back and perimeter are designed with a wraparound air duct and heating section, making full use of the space of the whole machine. When the air supply device 100 is turned on and heating, there is an atmosphere of flame burning in the middle, which, together with the hot air blowing from the perimeter, greatly improves the heating range and brings satisfaction from multiple aspects such as visual and physical sensation.

[0120] This application also provides a heater 200, which includes the aforementioned air supply device 100.

[0121] The aforementioned heater 200 has its air outlet 113 positioned around the periphery of the non-outlet area 111, rather than vertically. This allows the airflow to exit from the periphery of the non-outlet area 111. Compared to a vertically distributed design, the airflow from the heater 200 is more dispersed and less concentrated, and the outlet 113 covers a larger area for the same outlet area. When the heater 200 is running, it continuously draws in air from the back and blows it out from the front in a more dispersed manner. With separate air intake and outlet at the front and back of the heater 200, there is less mutual interference, resulting in more dispersed airflow, lower heat concentration, and a more comfortable heating effect.

[0122] In some embodiments, the heater 200 further includes a stand 210, which is connected to the air supply device 100. Specifically, the stand 210 is detachably connected to the air supply device 100. Thus, the air supply device 100 serves as the head of the heater, and the stand 210 supports the air supply device 100, enabling it to stand upright on a target surface such as the ground.

[0123] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0124] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
