[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the specification of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0033] Please refer toFigure 1 and Figure 2 Figure 2 , an embodiment of the present application provides an air supply device 100, which is used to convey air flow to the external environment and adjust the ambient temperature. The air supply device 100 includes a box body 10, a mounting bracket 20, an air supply device 30, and a grille 40. The grille 40 is used to ensure a large air outlet angle. The air supply device 100 can be a heater, a cooler, a tower fan, an air conditioner fan, or other air conditioning devices. In this embodiment, the air supply device 100 is a heater.
[0034] Please refer to Figure 2 and 3 3 , in an embodiment provided by the present application, the air supply device 100 includes a box body 10, a mounting bracket 20, an air supply device 30, and a grille 40. The box body 10 has an air inlet 101, a receiving space 102, and an air outlet 103 that are sequentially communicated. The mounting bracket 20 is disposed in the receiving space 102, and the air supply device 30 is mounted on the mounting bracket 20. The air supply device 30 has an air inlet side 301 and an air outlet side 302 that face away from each other. The air outlet side 302 faces the air outlet 103. When the air supply device 30 drives the air flow, a first air outlet area 105 is formed between the air outlet side 302 and the air outlet 103. The grille 40 is disposed on the air outlet side 302 and is located on the path of the air flow. The grille 40 includes a plurality of air guide plates 41, and the air guide plates 41 are used to guide the air flow and form a second air outlet area 106 on the side of the grille 40 facing outside the box body 10. The air outlet width of the second air outlet area 106 is greater than the air outlet width of the first air outlet area 105.
[0035] Please refer to Figures 4 to 6, the first air outlet area 105 can be understood as the interval area between the air supply device 30 and the air guide grille 40. The first air outlet area 105 has a first width boundary line 1051 and a second width boundary line 1052. The minimum distance b between the first width boundary line 1051 and the second width boundary line 1052 is the air outlet width of the first air outlet area 105. The air supply device 40 basically blows air vertically. The first width boundary line 1051 and the second width boundary line 1052 coincide with the left and right side boundary lines of the air supply device 30 respectively, that is, coincide with the left and right side boundary lines of the air outlet 103. Thus, the air outlet width of the first air outlet area 105 is basically equal to the width of the air supply device 40, that is, the air outlet width of the first air outlet area 105 is basically equal to the width of the air outlet 103. The second air outlet area 106 is the area where the air guide grille 40 extends to the outside. Two of the plurality of air guide plates 41 located on the left and right sides of the air outlet 103 respectively define a third width boundary line 1061 and a fourth width boundary line 1062 of the second air outlet area 106 along the extension line of the plate body. The minimum distance c between the third width boundary line 1061 and the fourth width boundary line 1062 defines the air outlet width of the second air outlet area 106. It should be noted that in this embodiment, each air guide plate 41 is inclined relative to the air supply device 30. The extension line of the air guide plate 41 along the extension direction of the plate body is located outside the straight line where the air inlet side 301 and the air outlet side 302 are located. Thus, the second air outlet area 106 is inclined relative to the first air outlet area 105, and the outline of the second air outlet area 106 is generally in the shape of an outward-expanded fan, while the outline shape of the first air outlet area 105 is generally rectangular. Thus, in the area where the air guide grille 40 admits air, the air outlet width of the second air outlet area 106 is greater than the air outlet width of the first air outlet area 105.
[0036] The magnitude of the aforementioned minimum distance b is equal to the width of the air outlet 103, and the shortest distance C is defined by two air guide plates 41 adjacent to the left and right sides of the air outlet 103. Specifically, please refer to Figure 7, the air outlet 103 has a third end 1031 and a fourth end 1032, and the distance between the third end 1031 and the fourth end 1032 defines the width of the air outlet 103, i.e., the minimum distance b. Among the plurality of air guide plates 41, there are an air guide plate 41 adjacent to the third end 1031 and an air guide plate 41 adjacent to the fourth end 1032. The distance between the end of the air guide plate 41 adjacent to the third end 1031 towards the outer side of the air outlet 103 and the end of the air guide plate adjacent to the fourth end 1032 towards the outside of the air outlet 103 is the shortest distance c. By providing the air guide grille 40, on the one hand, it can guide the air flow along the preset direction, accelerating the air flow efficiency; on the other hand, it can increase the air outlet angle of the air flow, covering a larger ventilation area. Specifically, the air guide plates 41 form a second air outlet area 106 on the side of the air guide grille 40 facing outside the box body 10. A first air outlet area 105 is formed between the air outlet side 302 of the air supply device 30 and the air outlet 103. The air flow can flow through the first air outlet area 105 to the air guide plates 41. Since the air outlet width of the second air outlet area 106 is greater than that of the first air outlet area 105, the air flow can be guided to the outside of the first air outlet area 105 and the air flow can be supplemented to the area not covered by the first air outlet area 105, so as to improve the air conditioning efficiency of the air supply device 100.
[0037] Next, each component of the air supply device 100 and the specific structure of each component will be introduced one by one.
[0038] Please refer to Figure 2 and Figure 3 , in this embodiment, the box body 10 is used to install components and protect the components. In this embodiment, the box body 10 includes a box body main body 11, and the box body main body 11 is approximately cylindrical in shape. It can be understood that the box body main body 11 can also be in the shape of a rectangular frame, a spherical shape or other shapes. The box body 10 also has an accommodation space 102, and the accommodation space 102 is used to install and place components. The components can be an installation bracket 20, an air supply device 30, an air guide grille 40, etc. The material of the box body 10 can include heat-resistant and flame-retardant plastic materials, resin materials or metal materials, which can protect the internal components from external damage and prevent users from touching high-temperature components and getting burned.
[0039] As an example, the material of the box body 10 can include ABS plastic, PC plastic or other hard plastics, which can not only reduce the weight of the air supply device 100 to achieve lightweight, but also enable the box body 10 to have a certain stability, thereby effectively protecting the components inside the box body 10. On the other hand, the plastic material can withstand moisture and high temperature, and at the same time has good tolerance for possible cleaning agents or disinfectants, which can increase the service life of the air supply device 100. It should be noted that the material of the box body 10 can also be ceramic material or other materials, and this embodiment does not limit this.
[0040] In this embodiment, an air inlet 101 for air intake and an air outlet 103 for air outlet are provided on the box body 11, and the air inlet 101, the accommodation space 102, and the air outlet 103 communicate with each other. As an example, the air inlet 101 and the air outlet 103 are oppositely arranged and located on the air flow path. After the external air flow enters the accommodation space 102 through the air inlet 101, it is then blown outwards through the air outlet 103, so that the external air flow can form an effective air flow circulation inside the air supply device 100, improving the air outlet efficiency. In some embodiments, a grid or a filter screen may be provided at the air inlet 101 and the air outlet 103 to filter dust and impurities in the inhaled air, keep the air supply device 30 clean, and extend the service life of the air supply device 100. A protective net or other safety measures may also be provided at the air outlet to prevent users from directly contacting the hot air and avoid burns.
[0041] In some embodiments, sound insulation materials (not shown in the figure) may also be filled inside the box body 10. The sound insulation materials may be foams or rubbers, etc., so as to reduce the noise generated during the operation of the air supply device 30 and at the same time protect the internal components from impacts during transportation and use. In other embodiments, the air supply device 100 may further include a tipping switch (not shown in the figure), which automatically shuts down when the air supply device 100 is tipped over, can prevent the occurrence of a fire or further damage, and improve the use safety of the air supply device 100.
[0042] Please refer to Figure 2 and Figure 3 , in this embodiment, the mounting bracket 20 is arranged in the accommodation space 102. The mounting bracket 20 is used to fix and support various internal components, ensuring the stability and safety of the components during operation. Specifically, the mounting bracket 20 can be divided into spaced-apart mounting areas 21 and connection areas 22. The mounting areas 21 and the connection areas 22 can be separated by spacers 23. The mounting areas 21 and the connection areas 22 are stacked, and the mounting area 21 is located above the connection area 22 in the direction of gravity. The spacer 23 can block the heat conduction between different areas to reduce the interference to different electronic devices. The mounting area 21 is used to mount the air supply device 30 and a circuit board (not shown in the figure). The circuit board is connected to the air supply device 30 to supply power to the air supply device 30. The connection area 22 is used to mount mounting components such as driving parts and stabilizing parts and fix the mounting bracket 20 to the box body 10 or the mounting base 60. By dividing the mounting bracket 20 into the mounting area 21 and the connection area 22, it is convenient for the installation and maintenance management of different components, makes the internal structure layout of the air supply device 100 more compact, and can enhance the heat exchange effect. The material of the mounting bracket 20 may include materials with high temperature resistance and high strength, such as plastic materials, metal materials, glass materials, etc. This embodiment does not make specific limitations on this.
[0043] In some embodiments, a spacer (not shown in the figure) or a spacer bracket 24 may be provided between the circuit board and the air supply device 30 to space the circuit board and the air supply device 30 apart. As an installation example, a spacer bracket 24 is provided between the circuit board and the air supply device 30, and the circuit board is disposed above the spacer bracket 24 relative to the air supply device 30. A wire routing hole (not shown in the figure) is formed in the spacer bracket 24, and the conductive wire routing passes through the wire routing hole and is connected between the circuit board and the air supply device 30. By providing the spacer bracket 24, the heat generated when the air supply device 30 operates can be reduced from directly contacting the circuit board upward, enabling the circuit board to be in a lower temperature region, which is beneficial to the service life of the circuit board. At the same time, the spacer bracket 24 also plays a certain heat insulation role, preventing the electronic devices from contacting each other and reducing heat conduction.
[0044] Please refer to Figure 3 and Figure 4 , in this embodiment, the air supply device 30 is installed on the mounting bracket 20, specifically in the mounting area 21 of the mounting bracket 20, and the air supply device 30 is used to drive the air flow when powered on. Specifically, the air supply device 30 has an air inlet side 301 and an air outlet side 302 facing away from each other. The air inlet side 301 is disposed facing the air inlet 101, and the air outlet side 302 is disposed facing the air outlet 103. The air supply device 30 may include a fan assembly 31, and the fan assembly is disposed on the air inlet side 301 to suck the outside air into the interior of the air supply device 100. The fan assembly 301 includes a driving motor (not shown in the figure) and a fan blade (not shown in the figure). The fan blade is connected to the driving motor, and the rotation speed of the fan blade is controlled by controlling the output power of the driving motor, thereby controlling the working efficiency of the air supply device 30.
[0045] In this embodiment, the air supply device 30 may further include a heating device 32. The heating device 302 is disposed on the air outlet side 302 and is located between the fan assembly 31 and the air guide grille 40. The heating device 32 is used to heat the air flow in the air supply device 100 to form hot air. Specifically, the outside air enters the interior of the air supply device 100 through the air inlet 101, flows from the air inlet side 301 to the periphery of the fan assembly 31, is blown by the fan assembly 31 to the heating device 32 for heating to form hot air, and the hot air is then guided to the outside through the air guide grille 40 at the air outlet 103. The heating device 32 may be a heating element, specifically, it may be an electric wire heating element, a ceramic heating element, a metal electric heating tube, a PTC heating element, etc., and this embodiment does not limit this. As an example, the heating device 32 is a PTC heating element, and the PTC heating element has the characteristics of small thermal resistance and high heat exchange efficiency, can quickly generate heat in a short time, and can improve the working efficiency of the air supply device 100.
[0046] It can be understood that the heating power of the heating device 32 is adjustable, so as to form hot air with various outlet air temperatures to meet the temperature requirements of different environments. In some embodiments, in order to further control the outlet air temperature of the air supply device 100, a temperature sensor (not shown in the figure) may be provided to detect the outlet air temperature. The temperature sensor may be provided at the air outlet 103 or around the heating device 32. This embodiment does not make specific limitations on this. It should be noted that when the air supply device 100 is a cold air blower or blows cold air, the heating device 32 may not be provided or the heating device 32 may not be turned on, so as to reduce the use cost.
[0047] In this embodiment, when the air supply device 30 drives the air flow, a first air outlet area 105 is formed between the air inlet side 301 and the air outlet. The flow direction of the air flow in the first air outlet area 105 is generally a straight line perpendicular to the extension direction of the mounting bracket 20, specifically, it can be perpendicular to the thickness direction of the heating device 32. When the air flow propagates from the first air outlet area 105 to the air guide grille 40, the flow direction of the air flow changes and expands relative to the flow direction of the air flow in the first air outlet area 105, so as to increase the air outlet range. The expansion can be understood as: the flow direction of the air flow in the second air outlet area 105 expands towards the outside of the straight line where the air flow direction in the first air outlet area 105 is located, that is, the air flow in the second air outlet area 105 expands outward relative to the central position of the first air outlet area 105, as Figure 6 shown. Specifically, the plurality of air guide plates 41 of the air guide grille 40 form a second air outlet area 106 on the side facing outside the box body 10. The air outlet direction of the second air outlet area 106 expands relative to the air outlet direction of the first air outlet area 105, so that the air outlet width of the second air outlet area 106 is greater than the air outlet width of the first air outlet area 105.
[0048] Please refer to Figure 4 、 Figure 7In this embodiment, the air guide grille 40 is used to guide the air flow and change the air outlet direction of the air flow at the air outlet. The air guide grille 40 is arranged on the air outlet side 302 and is located on the path of the air flow. The air guide grille 40 has an arc portion 403, so that the air guide grille 40 is extended and arranged roughly in an arc shape. The air guide grille 40 is arranged around the outer periphery of the mounting bracket 20. The air guide grille 40 can be fixed inside the box body 10. The air guide grille 40 can include a plurality of air guide plates 41. Since the air guide grille 40 is arranged in an arc or circumference, the air guide plates 41 are arranged at intervals along the extension direction of the circumference, and air guide gaps 42 are formed between adjacent air guide plates 41. The air flow can flow to the outside from the plurality of air guide gaps 42. When the air supply device 100 is placed on the installation plane for normal use, the air guide plate 41 is extended toward the side away from the installation plane to cover the height direction of the air outlet 103. Further, the size of the air guide grille 40 along the arc extension direction is greater than the size of the air outlet 103 along the arc extension direction, that is, the width of the air guide grille 40 is greater than the width of the air outlet 103, so that the air guide grille 40 covers the air outlet 103, thereby ensuring that the airflow flows to the air outlet after passing through the air guide grille 40. Specifically, the air guide grille 40 has a first end 401 and a second end 402 along the arc extension direction, and a plurality of air guide plates 41 are arranged between the first end 401 and the second end 402. The air outlet 103 has a third end 1031 and a fourth end 1032 along the arc direction, that is, the third end 1031 and the fourth end 1032 define the width direction of the air outlet 103. The distance between the third end 1031 and the fourth end 1032 is smaller than the distance between the first end 401 and the second end 402, so that the entire air outlet cross-section of the air outlet 103 is always connected to at least a part of the multiple air guide gaps 42 in the air guide grille 40, and the mounting bracket 20 can be installed in the center of the arc.
[0049] See also Figure 6 and Figure 8, in this embodiment, a plurality of air guiding plates 41 are sequentially arranged at intervals along the extending direction of the arc on the outer periphery of the mounting bracket 20. Each air guiding plate 41 has an air inlet end 411 and an air outlet end 412 facing away from each other. The air inlet end 411 communicates with the air outlet side 302 and faces the air supply device 30, and the air outlet end 412 faces the outside. The connection line between the air inlet end 411 and the air outlet end 412 defines the second air outlet direction L2 of the air flow in the second air outlet area 106, and the connection line between the air inlet side 301 and the air outlet side 302 defines the first air outlet direction L1 of the air flow in the first air outlet area 105. The straight line where the second air outlet direction L2 is located deviates from the straight line where the first air outlet direction L1 is located, and the straight line where the second air outlet direction L2 is located extends outward relative to the straight line where the first air outlet direction L1 is located. There is an included angle a between the two, and the included angle a makes the air outlet width of the second air outlet area 106 greater than the air outlet width of the first air outlet area 105 so that the air supply device 100 can cover a wider air outlet area. Only as an example, the angle value range of the included angle a is 5° to 20° (including the endpoints), specifically it can be 5°, 10°, 15°, etc., so that the second air outlet area 106 increases by a sector area with a central angle of 5° or 10° or 15° relative to the left and right sides of the first air outlet area 105, can cover more ventilation areas, and improve the air outlet efficiency of the air supply device 100.
[0050] It should be noted that the included angle can also be other values, and other values such as 30°, 35°, 40°, etc. can be set according to actual usage requirements, so that the air outlet width of the air supply device 100 in the second air outlet area 106 increases, and a larger air outlet area can be formed. This embodiment does not specifically limit the included angle between the straight line where the second air outlet direction L2 is located and the straight line where the first air outlet direction L1 is located.
[0051] In some other embodiments, each air guiding plate 41 is arranged to extend radially along the circumferential path of the arc surface, and the connection line between the air inlet side 301 and the air outlet side 302 of the air supply device 30 is parallel to the connection line from the center of the circumferential path to the central axis of the air outlet 103. Thus, the straight line from the air inlet end 411 to the air outlet end 412 of the air guiding plate 41 extends outward relative to the straight line between the air inlet side 301 and the air outlet side 302 of the air supply device 30, and there is the above-mentioned included angle a between the two. At this time, the included angles a along the circumferential path increase from the middle to both sides along the connection line from the center to the central axis of the air outlet 103. This embodiment does not limit this.
[0052] It should be noted that any of the above-mentioned embodiments is described on the basis that the air supply device 100 does not have a swinging function, that is, the box body 10 will not rotate, and the mounting bracket 20 and the air supply device 30 are both fixed inside the box body 10. In order to further increase the air outlet area of the air supply device 100, the air supply device 100 can also be set to have a swinging function, and any of the above-mentioned embodiments is also applicable to the following air supply device 100 with a swinging function.
[0053] In this embodiment, the box body 10 can rotate so that the air supply device 100 has a swinging function. During the rotation of the box body 10, the air outlet 103 also rotates towards different areas accordingly, so as to further increase the air outlet area of the air supply device 100. In order to improve the air outlet efficiency and air outlet quality, the mounting bracket 20 can also rotate accordingly so that the air supply device 30 rotates with the mounting bracket 20, so that there is more air volume at the air outlet.
[0054] Please refer to Figure 9 and Figure 10, specifically, in this embodiment, the cabinet 10 and the mounting bracket 20 can rotate about the central axis of the mounting bracket 20. The extending direction of the central axis is parallel to the height direction of the mounting bracket 20. During the rotation, the first air outlet area 105 includes a first sub-area 1053 and a second sub-area 1054, and the second air outlet area 106 includes a third sub-area 1063 and a fourth sub-area 1064. When the cabinet 10 and the mounting bracket 20 rotate to the left about the central axis, a first sub-area 1053 is formed between the air supply device 30 and the air guide grille 40, and the air guide grille 40 extends to the outside to form a third sub-area 1063. When the cabinet 10 and the mounting bracket 20 rotate to the right about the central axis, a second sub-area 1054 is formed between the air supply device 30 and the air guide grille 40, and the air guide grille 40 extends to the outside to form a fourth sub-area 1064. Similarly, the first sub-area 1053 has a fifth width boundary line 1055 and a sixth width boundary line 1056, and the second sub-area 1054 has a seventh width boundary line 1057 and an eighth width boundary line 1058. The third sub-area 1063 has a ninth width boundary line 1065 and a tenth width boundary line 1066, and the fourth sub-area 1064 has an eleventh width boundary line 1067 and a twelfth width boundary line 1068. The definitions of the fifth width boundary line 1055, the sixth width boundary line 1056, the seventh width boundary line 1057, and the eighth width boundary line 1058 can refer to the first width boundary line 1051 and the second width boundary line 1052 mentioned above. The definitions of the ninth width boundary line 1065, the tenth width boundary line 1066, the eleventh width boundary line 1067, and the twelfth width boundary line 1068 can refer to the third width boundary line 1061 and the fourth width boundary line 1062 mentioned above. The minimum distance b between the fifth width boundary line 1055 and the eighth width boundary line 1058 defines the air outlet width of the first air outlet area 105, and the minimum distance c between the ninth width boundary line and the twelfth width boundary line defines the air outlet width of the second air outlet area 106. It can be understood that the first sub-area 1053 and the second sub-area 1054 at least partially overlap, so that the third sub-area 1063 and the fourth sub-area 1064 at least partially overlap. The above "rotation to the left" can be understood as the cabinet 10 rotating from the first end 401 to the second end 402 of the air guide grille 40, and the rotation to the right is the opposite.
[0055] The air supply device 30 has opposite left and right ends, and the distance between the left and right ends defines the width of the air supply device 30. During the left and right swinging of the air supply device 100, the distance between the left end of the air supply device 30 when it rotates to the left and the right end of the air supply device 30 when it rotates to the right defines the aforementioned minimum distance b. When the air supply device 30 rotates to the left, among the plurality of air guide plates 41, there is a first air guide plate 4101 with the shortest distance from the left end of the air supply device 30. When the air supply device 30 rotates to the right, among the plurality of air guide plates 41, there is a second air guide plate 4102 with the shortest distance from the right end of the air supply device 30. The distance between one end of the first air guide plate 4101 facing the air outlet 103 when the air supply device 100 swings to the left and one end of the second air guide plate 4102 facing the outside of the air outlet 103 when the air supply device 100 swings to the right defines the minimum distance c.
[0056] Please refer to again Figure 2 , specifically, the air supply device 100 further includes a driving device 50. The driving device 50 is arranged in the box body 10, and the driving device 50 is connected to the mounting bracket 20. As an example, a first connecting portion 221 extending towards the driving device 50 is provided in the connecting area 22 of the mounting bracket 20, and a second connecting portion 501 cooperating with the first connecting portion 221 is provided on the driving device 50. The first connecting portion 221 is detachably connected to the second connecting portion 501 for easy installation and maintenance. When the driving device 50 operates, the driving device 50 drives the mounting bracket 20 to rotate in a circle with the output shaft of the driving device 50 as the center, so that the air supply device 30 rotates relative to the air guide grille 40. The dimension of the arc surface portion 403 ( Figure 5 ) of the air guide grille 40 along the circumferential rotation path is larger than the dimension of the air outlet 103 along the circumferential path.
[0057] Please refer to FIG. Figure 11In this embodiment, the housing 10 can rotate so that the air outlet 103 can rotate to different directions to discharge air and increase the air supply area. As an example, the air guide grille 40 is fixed inside the housing 10, and the housing 10 is connected to the driving device 50 by transmission. When the driving device 50 drives the mounting bracket 20 to rotate, the housing 10 will also rotate accordingly. The rotation direction of the housing 10 is consistent with the rotation direction of the mounting bracket 20 at this time, and both are circular rotations. It can be understood that since the housing 10 and the mounting bracket 20 rotate left and right relative to the air guide grille 40, in order to ensure that the airflow generated by the air supply device 30 during the rotation process flows from the air guide grille 40 to the outside, the entire cross-sectional area of the air outlet 103 and at least a portion of the multiple air guide gaps 42 formed by the air guide plate 41 are always connected. As a specific example, when the box 10 is rotated to the extreme position relative to the air guide grille 40, the third end 1031 of the air outlet 103 coincides with the first end 401 of the air guide grille 40; or the fourth end 1032 of the air outlet 103 coincides with the second end 402. The rotation angle range of the box 10 and the mounting bracket 20 can be 0 to 40° (including the end points) to ensure the stability and durability of the air supply device 100 during rotation. Specifically, the rotation range of the box 10 and the mounting bracket 20 can be 5°, 10°, 15°, 35°, etc., and this embodiment does not impose specific restrictions on this. In addition, the rotation angle range is the rotation angle range of the mounting bracket 20 or the box 10 to either side of the output shaft 51 of the driving device 50, that is, the central axis of the mounting bracket 20 as the center of the circle, and the mounting bracket 20 or the box 10 to the left or right of the output shaft 51. It is understandable that, on the basis that the air supply device 100 has good structural strength and stability, the rotation angle range of the box body 10 and the mounting bracket 20 can also be larger to supply air to more areas.
[0058] See also Figure 11 and Figure 12, in this embodiment, the rotation of the mounting bracket 20 and the limitation of the rotation angle of the mounting bracket 20 are both realized by the driving device 50. Specifically, the air supply device 100 further includes a base 60, and the base 60 is movably connected to the box body 10, so that the box body 10 can rotate under the drive of the driving device 50 or when pushed by the user. The box body 10 encloses the accommodating space 102 and is supported on the use platform, and the use platform can be the ground, a desktop or other installation planes. The driving device 50 may include a driving motor 52, a rotating bracket 53 and a rotating disc 54. The rotating disc 54 is fixed to the base 60, the rotating bracket 53 is connected between the rotating disc 54 and the mounting bracket 20, and the driving motor 52 is connected to the rotating bracket 53 to drive the rotating bracket 53 to rotate so as to drive the mounting bracket 20 and the air supply device 30 to rotate. Specifically, the rotating disc 54 and the rotating bracket 53 are coaxially arranged, the rotating disc 54 is provided with a mounting portion (not shown in the figure), the mounting portion is provided with a sliding rail (not shown in the figure), and the rotating bracket 20 is mounted on the mounting portion and slides in cooperation with the sliding rail under the drive of the driving device 50.
[0059] Please refer to Figure 12 and Figure 13 , in this embodiment, the driving device 50 includes a transmission assembly 55, and by setting the transmission assembly, the stability of the air supply device 100 shaking its head is improved. Specifically, a first chute 531 is formed on the rotating bracket, and the first chute 531 extends along the rotation path of the transmission assembly 55. The transmission assembly 55 includes a transmission rod 551 and a connecting member 552. The transmission rod 551 is connected between the driving motor 52 and the connecting member 552, and the connecting member 552 passes through the first chute 531 and is connected to the rotating disc 54. Under the drive of the driving motor, the push rod 551 and the connecting member 552 rotate with the rotating bracket 53 to provide a stable swinging motion, ensuring that the air supply device 100 does not shake or become unstable during the process of shaking its head.
[0060] In this embodiment, the rotating bracket 53 further includes a second chute 532, and the rotating disc 54 further includes a limiting member 541. The number of the two second chutes 532 and the limiting members 541 can be two, and the two second chutes 532 and the limiting members 541 are arranged in one-to-one correspondence. By setting the second chute 532 and the limiting member 541, the rotation angle of the rotating bracket 53 is limited. Specifically, the two second chutes 532 are arranged at intervals, and the two limiting members 541 protrude toward one side of the rotating bracket 53, and each limiting member 541 passes through the corresponding second chute 532. During the driving process of the driving motor 52, when the rotating bracket 53 rotates clockwise or counterclockwise relative to the rotating disc 54 to the limit angle, one of the second chutes 532 abuts against the corresponding limiting member 541, so that the rotating bracket 53 can no longer rotate in the same direction to achieve the purpose of limiting the rotation angle.
[0061] It should be noted that in some other embodiments, the air guiding grille 40 can also rotate. Specifically, the air guiding grille 40 is drivingly connected to the driving device 50, and can be specifically connected to the rotating bracket 53, so that the driving device 50 drives the box body 10, the mounting bracket 20 and the air guiding grille 40 to rotate synchronously. At this time, the box body 10, the mounting bracket 20 and the air guiding grille 40 are located on the same plane at the same time.
[0062] In summary, the embodiment of the present application provides an air supply device 100, which includes a box body 10, a mounting bracket 20, an air supply device 30 and an air guiding grille 40. The air flow conveyed by the air supply device 30 flows to the outside through the air guiding grille 40. By setting the air guiding grille 40, on the one hand, it can guide the air flow along the preset direction of the flow direction, accelerating the flow efficiency of the air flow; on the other hand, it can increase the air outlet angle of the air flow, covering a larger ventilation area. Specifically, the air guiding grille 40 is provided with a plurality of air guiding plates 41, and the air guiding plates 41 form a second air outlet area 106 on the side of the air guiding grille 40 facing outside the box body 10. A first air outlet area 105 is formed between the air outlet side 302 and the air outlet of the air supply device 30, and the air flow can flow to the air guiding plates 41 through the first air outlet area 105. Since the air outlet width of the second air outlet area 106 is greater than the air outlet width of the first air outlet area 105, the air flow can be led out to the outside of the first air outlet area 105, and the area covered by the air flow is relatively large, so as to improve the air outlet efficiency of the air supply device 100.
