Description

Technical Field

[0001] The present application relates to the technical field of air supply equipment, and in particular to an air duct structure and an air supply device. Background Art

[0002] A wind shield structure is usually provided at the air duct opening of an air supply device (such as a fan, heater, cooler, or humidifier) ​​to enable the opening and closing of the air duct.

[0003] In the related art, connecting parts are provided on both sides of the windshield, and one of the connecting parts rotates around a preset rotation axis under the drive of a driving mechanism such as a motor, thereby causing the windshield to move relative to the air duct to open and close the air duct.

[0004] This windshield structure is connected to the motor only through a connecting part on one side. Although it is simple and easy to assemble, the connecting part on the other side is only supported on the air duct because it is not directly driven by the motor. The two sides of the windshield are unevenly stressed, and it is easy to get stuck during movement, resulting in poor sealing of the windshield to the air duct. It is also easy to produce abnormal noise, which affects the air outlet effect of the air supply device and the user experience. Summary of the Invention

[0020] In one embodiment, the driving member includes a power source and a connecting rod, the power source is installed in the air duct, and the connecting rod connects the power source and the transmission part;

[0021] The power source is used to drive the connecting rod to swing around the rotation axis.

[0022] In one embodiment, the air duct includes a main inlet, a first outlet and a second outlet.

[0047] See also Figure 1 、 Figure 2 and Figure 3 In some embodiments of the present application, a duct structure 100 is provided, comprising an duct 10, a drive member 20, and a windshield member 30. The inner wall of the duct 10 is constructed with at least two guide portions 10a. The windshield member 30 is disposed within the duct 10. A transmission portion 31 and at least two sliding portions 32 are jointly constructed on two opposing sides of the windshield member 30 along a first direction X. The transmission portion 31 and some of the sliding portions 32 are disposed on one side, while the remaining sliding portions 32 are disposed on the other side. The drive member 20 is connected to the transmission portion 31 and is configured to drive the transmission portion 31 to perform circular motion relative to the duct 10 about a rotation axis Z parallel to the first direction X, so that the windshield member 30 opens and closes the duct 10. The sliding portion 32 is slidably connected to a corresponding guide portion 10a.

[0048] The air duct 10 is a structure having a flow channel through which air can flow. It can be, but is not limited to, a shell-shaped component, and can be made of plastic, metal, or the like. It is understood that the air duct 10 has an inlet and an outlet. The windshield 30 can be disposed at the inlet or outlet of the air duct 10, or at a position within the air duct 10 between the inlet and outlet. The specific location of the windshield 30 within the air duct 10 is not limited.

[0049] The windshield 30 may be, but is not limited to, a plate-shaped member disposed within the air duct 10. When driven by the driver 20, it can open or close the air duct 10. The windshield 30 opening the air duct 10 means that the windshield 30 does not prevent air from flowing within the air duct 10. The windshield 30 closing the air duct 10 means that the windshield 30 blocks the path of air flowing within the air duct 10. The windshield 30 opening or closing the air duct 10 may be achieved by opening or closing the entrance or exit of the air duct 10, or by opening or closing an intermediate portion of the air duct 10.

[0050] The driving member 20 can be arranged outside the air duct 10 without occupying the space of the air duct 10, and is also convenient for installation. Of course, the driving member 20 can also be arranged inside the air duct 10, which is not specifically limited.

[0051] The windshield 30 is constructed with a transmission portion 31 and at least two sliding portions 32 on two opposite sides in the first direction X, where the "opposite sides" are defined as a first side f1 and a second side f2 (e.g. Figure 3 (as shown), the transmission portion 31 of the windshield 30 is located on at least one of the first side f1 and the second side f2, and both the first side f1 and the second side f2 are configured with a sliding portion 32. The guide portion 10a of the air duct 10 corresponds to the sliding portion 32 in a one-to-one manner. The sliding portion 32 can slide along the guide portion 10a, and the guide portion 10a guides the sliding of the sliding portion 32.

[0052] The transmission portion 31 is in transmission connection with the driving member 20. The driving member 20 can drive the transmission portion 31 to rotate about the rotation axis Z. When the transmission portion 31 rotates, it forms an arc-shaped motion trajectory on the air duct 10. In other words, the transmission portion 31 moves in an arc about the rotation axis Z. When the transmission portion 31 moves, the sliding portion 32 also slides along the corresponding guide portion 10a.

[0053] The transmission part 31 and the sliding part 32 can be a shaft, a block, a rod or other structure that is protruding on the first side f1 or the second side f2 of the windshield 30 along the first direction X. In this case, the guide part 10a can be a guide groove. The transmission part 31 and the sliding part 32 can also be a hole structure that is recessed on the first side f1 or the second side f2 of the windshield 30 along the first direction X. In this case, the guide part 10a can be a guide rail, and there is no specific limitation. As long as the transmission part 31 can be connected to the driving member 20 for transmission, and drives the sliding part 32 to slide along the guide part 10a in the process of rotating around the rotation axis Z. For example, the transmission part 31 is a transmission shaft, the sliding part 32 is a sliding shaft, the guide part 10a is a sliding groove, the sliding shaft is slidably connected to the sliding groove, and the transmission shaft is drivingly connected to the driving member 20.

[0054] In actual operation of the air duct structure 100, when the driving member 20 drives the transmission portion 31 located on one side of the windshield member 30 to perform circular motion around the rotation axis Z, the sliding portions 32 located on both sides of the windshield member 30 can slide along the corresponding guide portions 10a, thereby switching the windshield member 30 between the positions of opening the air duct 10 and closing the air duct 10. At the same time, the sliding portions 32 on both sides of the windshield member 30 cooperate with the guide portions 10a of the air duct 10. The air duct 10 can provide a relatively uniform supporting force to both sides of the windshield member 30 through the sliding portions 32. In other words, the force on both sides of the windshield member 30 is relatively uniform during movement, which can reduce problems such as abnormal noise and jamming caused by uneven force on both sides of the windshield member 30. This can improve the air outlet effect of the air supply device 1000 equipped with the air duct structure 100 and the user experience.

[0055] In some embodiments, please refer to Figure 5, on a plane perpendicular to the first direction X, the orthographic projection of the transmission part 31 is located between the orthographic projections of at least two sliding parts 32 .

[0056] The orthographic projection of the transmission part 31 is located between at least two sliding parts 32. The orthographic projections of at least two sliding parts 32 can be arranged in a straight line, and the orthographic projection of the transmission part 31 is located between the orthographic projections of two of the sliding parts 32. It can also be that the orthographic projections of at least two sliding parts 32 enclose the orthographic projection of the transmission part 31.

[0057] By way of example, the sliding parts 32 include two, the transmission part 31 is arranged on the first side f1 of the windshield 30, one of the sliding parts 32 is arranged on the first side f1 of the windshield 30, and the other sliding part 32 is arranged on the second side f2 of the windshield 30. The two sliding parts 32 are arranged diagonally such that the orthographic projection of the transmission part 31 is located between the orthographic projections of the two sliding parts 32. By way of another example, the sliding parts 32 include three, one of the sliding parts 32 is arranged on the first side f1 of the windshield 30, and the other two sliding parts 32 are arranged on the second side f2 of the windshield 30. The orthographic projection of the sliding part 32 arranged on the first side f1 is located on one side of the orthographic projection of the transmission part 31, and the orthographic projections of the two sliding parts 32 arranged on the second side f2 are both located on the other side of the orthographic projection of the transmission part 31.

[0058] At this time, in the orthographic projection on the plane perpendicular to the first direction X, the transmission part 31 is arranged between all the sliding parts 32, rather than being located on one side of all the sliding parts 32. The force exerted by the driving part 20 on the transmission part 31 can be transmitted to various parts of the windshield part 30 through the sliding part 32, that is, the windshield part 30 is subjected to more uniform force and the movement smoothness of the windshield part 30 is better.

[0059] For details about the embodiment, please refer to Figure 5 The transmission part 31 and all the sliding parts 32 are symmetrically arranged relative to the cross section of the wind shield 30 parallel to the first direction X.

[0060] It can be understood that the windshield member 30 has a cross-section parallel to the first direction X, one of which is a first cross-section. The transmission portion 31 and all sliding portions 32 are symmetrically arranged relative to this first cross-section. That is, the transmission portion 31 is symmetrical relative to the first cross-section, and all sliding portions 32 are symmetrical relative to the first cross-section. For example, if the windshield member 30 is a windshield plate, the thickness direction of the windshield plate lies within a plane perpendicular to the first direction X. The first cross-section is a plane parallel to the plane defined by the thickness direction and the first direction X.

[0061] When all the sliding parts 32 and the transmission parts 31 on the wind shield 30 are arranged symmetrically relative to the first cross-section, the forces transmitted to the wind shield 30 by the air duct 10 and the driving part 20 through the sliding parts 32 and the transmission parts 31 respectively are relatively uniform, that is, the wind shield 30 is subjected to force more evenly, which can further improve the smoothness of the movement of the baffle relative to the air duct 10 and improve the movement accuracy of the wind shield 30.

[0062] For details about the embodiment, please refer to Figure 5 All the sliding parts 32 are symmetrically arranged relative to the cross section of the wind shield 30 perpendicular to the first direction X.

[0063] It can be understood that the windshield member 30 has a cross section perpendicular to the first direction X, one of which is a second cross section. The transmission part 31 is located on one side of the first cross section, and all the sliding parts 32 are symmetrically arranged relative to the second cross section.

[0064] When all the sliding parts 32 on the windshield 30 are arranged symmetrically with respect to the second cross section, the air duct 10 can provide a relatively uniform supporting force to each sliding part 32 , so that the windshield 30 moves more smoothly.

[0065] In some embodiments, the transmission portion 31 is rotatably connected to the driving member 20 , or the transmission portion 31 is fixedly connected to the driving member 20 .

[0066] The fixed connection between the transmission portion 31 and the driver 20 means that the transmission portion 31, under the action of the driver 20, only moves in a circular motion about the rotation axis Z. The connection between the two can be made by interference fit, welding, heat fusion, fastening, etc. It is understood that when the transmission portion 31 is fixedly connected to the driver 20, the sliding path of the sliding portion 32 is also a circular arc path.

[0067] The transmission part 31 and the driving member 20 are rotatably connected, which means that the transmission part 31 can rotate while performing a circular motion around the rotation axis Z under the action of the driving member 20. The connection between the two can be a bearing connection, a clearance fit connection, etc.

[0068] It should be noted that the rotatable connection between the transmission portion 31 and the driver 20 does not necessarily mean that the transmission portion 31 must rotate during operation. For example, if the extension direction of the guide portion 10a is the same as the arc trajectory corresponding to the sliding portion 32 when the transmission portion 31 is fixedly connected to the driver 20, then even if the transmission portion 31 is rotatable relative to the driver 20, the transmission portion 31 may not rotate during the circular motion driven by the driver 20.

[0069] The force that causes the transmission portion 31 to rotate can come from the guide portion 10a guiding the sliding portion 32. For example, if the extending direction of the guide portion 10a differs from the arc trajectory of the sliding portion 32 when the transmission portion 31 is fixedly connected to the driver 20, the transmission portion 31 will rotate relative to the driver 20 under the restraint of the guide portion 10a, thereby supporting the movement of the sliding portion 32.

[0070] Regardless of whether the transmission part 31 is fixedly connected to the driving member 20 or rotatably connected, as long as the air duct 10 can be opened and closed during the movement of the wind shield 30, its specific setting method can be flexibly set according to the arrangement of the air outlet O of the air duct 10. In the embodiment of the present application, the connection method between the transmission part 31 and the driving member 20 is not restricted, so that there are multiple design possibilities for the movement process of the wind shield 30.

[0071] For details about the embodiment, please refer to Figure 5 , refer to Figure 6 and Figure 7 , at least two sliding parts 32 include a first sliding part 32a and a second sliding part 32b. On a plane perpendicular to the first direction X, the orthographic projection of the transmission part 31 is located between the orthographic projections of the first sliding part 32a and the second sliding part 32b, and the extension directions of the first guide part a1 and the second guide part a2 are arranged to intersect.

[0072] The extension direction of the first guide portion a1 corresponds to the movement direction of the first sliding portion 32a, and the extension direction of the second guide portion a2 corresponds to the movement direction of the second sliding portion 32b. In other words, the specific extension directions of the first guide portion a1 and the second guide portion a2 are determined by the position of the sliding portion 32 with which they are matched. Sliding portions 32 in different positions correspond to different movement trajectories, and thus the corresponding extension directions of the first guide portion a1 are different.

[0073] When the extension directions of the first guide portion a1 and the second guide portion a2 intersect, they may or may not intersect directly. Of course, the extension lengths of the first guide portion a1 and the second guide portion a2 can be greater than or equal to the movement length of the corresponding sliding portion 32, as long as the guide portions 10a do not restrict the sliding of the sliding portion 32. Of course, in some embodiments, the length of the guide portion 10a can also be used to limit the movement length of the sliding portion 32, thereby controlling the rotation angle of the transmission portion 31. The specific configurations are flexible and diverse and are not limited in the present embodiments.

[0074] During actual operation, when the transmission part 31 rotates to the end where the first sliding part 32a slides the first guide part a1 away from the second guide part a2, the wind shield 30 is in the first extreme state; when the transmission part 31 rotates to the end where the second sliding part 32b slides the second guide part a2 away from the first guide part a1, the wind shield 30 is in the second extreme position.

[0075] When the wind shield 30 is used to open or close the air outlet O of the air duct 10, when the wind shield 30 switches between the first limit position and the second limit position, the wind shield 30 is used to open or close the air outlet O. If the wind shield 30 has multiple air outlets O, the wind shield 30 can be used to close one of the air outlets O in the first limit position and can be used to close another air outlet O in the second limit position.

[0076] At this time, the extension directions of the first guide part a1 and the second guide part a2 intersect, and when the wind shield 30 moves between the two extreme positions, it can adapt to the air duct 10 having two intersecting air outlets O. Switching between the two air outlets O of the air duct 10 can be achieved using one wind shield 30.

[0077] It should be noted that when the transmission part 31 is located on the first side f1 of the wind shield 30, the first sliding part 32a and the second sliding part 32b can be located on the first side f1 of the wind shield 30 at the same time, or on the second side f2 of the wind shield 30 at the same time, or one is located on the first side f1 and the other is located on the second side f2, as long as the condition "on the plane perpendicular to the first direction X, the orthographic projection of the transmission part 31 is located between the orthographic projections of the first sliding part 32a and the second sliding part 32b" is satisfied.

[0078] Specifically, in this embodiment, the transmission portion 31 is rotatably connected to the driver 20, and the first guide portion a1 and the second guide portion a2 are both arranged to extend in a straight line. In this case, the first guide portion a1 and the second guide portion a2 both extend in a straight line. Driven by the driver 20, the transmission portion 31 simultaneously rotates while performing circular motion around the rotation axis Z. When the air duct 10 includes the main inlet I, the first outlet U1, and the second outlet U2 described in the following embodiments, the windshield 30 can more closely fit the air duct 10 when opening the first outlet U1 or the second outlet U2, thereby improving the airtightness of the air duct 10 and reducing air leakage.

[0079] The first guide portion a1 and the second guide portion a2 may be arranged at an obtuse angle or a right angle.

[0080] For details about the embodiment, please refer to Figure 5 , refer to Figure 6 and Figure 7 There are two first sliding parts 32a and two second sliding parts 32b, and the two first sliding parts 32a are symmetrically arranged on both sides, and the two second sliding parts 32b are symmetrically arranged on both sides. There are two first guide parts a1 and two second guide parts a2.

[0081] Here, "two sides" refers to two opposite sides of the windshield 30 in the first direction X. The two first sliding portions 32a are symmetrically arranged with respect to a cross section of the windshield 30 perpendicular to the first direction X, and the two second sliding portions 32b are symmetrically arranged with respect to a cross section of the windshield 30 perpendicular to the first direction X. Accordingly, two first guide portions a1 and two second guide portions a2 are provided, and are symmetrically arranged with respect to a cross section of the windshield 30 perpendicular to the first direction X.

[0082] At this time, the first sliding part 32a, the second sliding part 32b, the first guide part a1 and the second guide part a2 are all arranged in pairs and symmetrically, so that the wind shield 30 can be evenly stressed when moving along the air duct 10. The movement process of the wind shield 30 is smoother, and the jamming and abnormal noise generated by the movement are greatly reduced, which helps to improve the air outlet effect and user experience of the air supply device 1000 equipped with the air duct structure 100.

[0083] In some embodiments, please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The driving member 20 is located outside the air duct 10. The air duct 10 is constructed with an arc groove 10b that passes through the air duct 10. The center of the arc groove 10b is located on the rotation axis Z. The transmission part 31 or the driving member 20 is passed through the arc groove 10b.

[0084] When the transmission portion 31 is provided with the circular arc groove 10b, the transmission portion 31 can be a transmission shaft or a transmission rod, which extends from the interior of the air duct 10 through the circular arc groove 10b to the outside of the air duct 10 and is in transmission connection with the driving member 20. When the driving member 20 is provided with the circular arc groove 10b, it is the portion of the driving member 20 that is in transmission connection with the transmission portion 31 that is provided with the circular arc groove 10b. For example, if the transmission portion 31 is a transmission hole, the driving member 20 has a transmission shaft, and the transmission shaft is inserted into the transmission hole through the circular arc groove 10b to achieve connection with the transmission portion 31.

[0085] The setting of the arc groove 10b makes the movement smoother under the guidance of the arc groove 10b during the rotation of the transmission part 31 or the driving part 20 around the rotation axis Z. At the same time, the arc groove 10b can also increase the supporting effect of the air duct 10 on the wind shield 30, thereby improving the smoothness of the wind shield 30 during the movement.

[0086] In some embodiments, please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The driving member 20 includes a power source 21 and a connecting rod 22. The power source 21 is installed in the air duct 10. The connecting rod 22 connects the power source 21 and the transmission part 31. The power source 21 is used to drive the connecting rod 22 to swing around the rotation axis Z.

[0087] The power source 21 can be a rotating motor that can be fixed to the air duct 10 by bolts, threads, or the like. The power source 21 is typically positioned outside the air duct 10 to reduce the resistance to air flowing within the air duct 10. Of course, the power source 21 can also be other power structures, and those skilled in the art can make conventional arrangements, which are not specifically limited herein.

[0088] One end of the connecting rod 22 is connected to the driving end of the power source 21. Specifically, the connecting rod 22 is fixedly connected to the driving shaft of the motor or connected through a coupling. The other end of the connecting rod 22 is fixedly connected to the transmission part 31 or hinged, without limitation.

[0089] At this time, the movement of the transmission part 31 is achieved by the combination of the power source 21 and the connecting rod 22, and the structure is simple and easy to implement.

[0090] In some embodiments, please refer to Figure 1 、 Figure 2 、 Figure 4 、 Figure 6 and Figure 7 The air duct 10 includes a main inlet I, a first outlet U1 and a second outlet U2. When the transmission part 31 moves, the wind shield 30 switches between a first state of cutting off the main inlet I and the first outlet U1 and a second state of cutting off the main inlet I and the second outlet U2.

[0091] In actual application, when the air duct structure 100 is applied to an air supply device 1000, the main inlet I serves as the entrance for air to enter the air duct 10 and can be connected to a power device such as a fan that promotes air movement in the air supply device 1000. The first outlet U1 can be connected to one air outlet O of the air supply device 1000, and the second outlet U2 can be connected to another air outlet O of the air supply device 1000.

[0092] When the wind shield 30 switches between the first state and the second state, the air can be sent to two different air outlets O, thereby changing the air outlet mode of the air supply device 1000 .

[0093] exist Figure 1 In the embodiment shown, the windshield member 30 is in the second state. Figure 2 In the illustrated embodiment, the wind shield 30 is located in the first state.

[0094] In one specific embodiment, when the air duct 10 has the above-mentioned main inlet I, first outlet U1, and second outlet U2, one construction method of the air duct structure 100 is as follows: the transmission portion 31 of the windshield 30 is rotatably connected to the driving member 20, and the windshield 30 includes a first sliding portion 32a and a second sliding portion 32b. Accordingly, the air duct 10 is provided with a first guide portion a1 and a second guide portion a2, and the first guide portion a1 and the second guide portion a2 both extend in a straight line. When the first sliding portion 32a slides to the end of the first guide portion a1 away from the second guide portion a2, the windshield 30 is in the second state and closes the second outlet U2. When the second sliding portion 32b slides to the end of the second guide portion a2 away from the first guide portion a1, the windshield 30 is in the first state and blocks the main inlet I and the first outlet U1.

[0095] In some embodiments, please refer to Figure 4 、 Figure 6 and Figure 7 The air duct 10 includes a first wind shell 11 and a second wind shell 12, both of which are constructed with a guide portion 10a. The first wind shell 11 and the second wind shell 12 are matched along the first direction X. The driving member 20 and the transmission portion 31 are arranged on the first wind shell 11, and the sliding portion 32 arranged on one side is slidably connected to the guide portion 10a on the first wind shell 11, and the sliding portion 32 arranged on the other side is slidably connected to the guide portion 10a on the second wind shell 12.

[0096] The first air housing 11 and the second air housing 12 are spliced ​​together along the first direction X to form the air duct 10. The first air housing 11 and the second air housing 12 can be fixed together by means of snap connection, thread connection, etc., which are not limited to specific methods. The first air housing 11 and the second air housing 12 can be made of plastic.

[0097] During actual installation, the guide portion 10a on the first air housing 11 is connected to the corresponding sliding portion 32 on the windshield 30, and then the guide portion 10a on the second air housing 12 is connected to the corresponding sliding portion 32 on the windshield 30. The first and second air housings 11 and 12 are then fixedly connected. The driver 20 is then installed on the first air housing 11 and mated with the transmission portion 31, thus completing the assembly of the air duct structure 100. Motor mounting positions 10d and 10c can be provided on the first air housing 11 to mount the motor of the driver 20.

[0098] At this time, the air duct 10 is divided into two air shells, so that the air duct structure 100 can be quickly disassembled and assembled.

[0099] In some embodiments, please refer to Figure 4 and Figure 5 An installation position 10 c is provided in the air duct 10 , and the installation position 10 c is used to install a temperature-changing component for heating or cooling the gas flowing through the air duct 10 .

[0100] The temperature-changing component may be a heating element, a cooling element, or the like. The heating element may be a resistive heating element or an infrared heating element. The cooling element may be a semiconductor cooling fin, or the like. The specific structure of the temperature-changing component is not limited in the embodiments of this application.

[0101] The installation position 10c is used to install the temperature-changing component, and can specifically be a mounting hole, a mounting card position, a plug-in position, etc. Its specific structure is not specifically limited in the embodiment of the present application, as long as the installation of the temperature-changing component can be achieved.

[0102] When the gas flows through the temperature-variable component installed at the installation position 10c, it can be heated or cooled by the temperature-variable component, so that cold air or warm air can be discharged, thereby enriching the air outlet mode of the air supply device 1000.

[0103] In the air duct structure 100 provided in the embodiment of the present application, when the driving member 20 drives the transmission portion 31 located on one side of the windshield member 30 to perform circular motion around the rotation axis Z, the sliding portions 32 located on both sides of the windshield member 30 can slide along the corresponding guide portions 10a, thereby switching the windshield member 30 between the positions of opening and closing the air duct 10. At the same time, the sliding portions 32 on both sides of the windshield member 30 cooperate with the guide portions 10a of the air duct 10. The air duct 10 can provide relatively uniform support force to both sides of the windshield member 30 through the sliding portions 32. In other words, the force on both sides of the windshield member 30 is relatively uniform during movement, which can reduce problems such as abnormal noise and jamming caused by uneven force on both sides of the windshield member 30. This can improve the air outlet effect of the air supply device 1000 equipped with the air duct structure 100 and the user experience.

[0104] Based on the same invention concept, please refer to Figure 8 The embodiment of the present application further provides an air supply device 1000, comprising an air outlet O and the air duct structure 100 of any of the above embodiments, wherein the air duct structure 100 is in communication with the air outlet O. The air supply device 1000 comprises the above air duct structure 100, and thus has all the above beneficial effects, which are not described in detail here.

[0105] The air supply device 1000 can be a cooling fan, a heating fan, a cooling and heating fan, a water fan, a dehumidifier, etc., as long as it can achieve air supply. It can be understood that the outlet of the air duct 10 is connected to the air outlet O. The air supply device 1000 can also include a power component consisting of a fan, a volute, etc.

[0106] In some embodiments, please refer to Figure 8 , and combined with Figure 1 and Figure 2The air duct 10 includes a main inlet I, a first outlet U1, and a second outlet U2. During the movement of the transmission unit 31, the windshield 30 switches between a first state that blocks the main inlet I and the first outlet U1, and a second state that blocks the main inlet I and the second outlet U2. The air supply device 1000 includes a first air outlet O1 and a second air outlet O2. The first air outlet O1 is connected to the first outlet U1, and the second air outlet O2 is connected to the second outlet U2.

[0107] When the wind shield 30 is in the first position, the main inlet I, second outlet U2, and second air outlet O2 of the air duct 10 are connected, and air is discharged through the second air outlet O2 of the air supply device 1000. When the wind shield 30 is in the second position, the main inlet I, first outlet U1, and first air outlet O1 of the air duct 10 are connected, and air is discharged through the first air outlet O1 of the air supply device 1000.

[0108] At this time, the switching air supply of the two air outlets O of the air supply device 1000 can be achieved through one air duct 10, which has a simple structure and helps to reduce the equipment cost of the air supply device 1000.

[0109] The first air outlet O1 can be a warm air outlet, and the second air outlet O2 can be a cold air outlet. Furthermore, the warm air outlet is located below the cold air outlet. The hot air blown out of the warm air outlet rises from low to high, and the cold air blown out of the cold air outlet descends from high to low. The air supply device 1000 has good warm air and cold air discharge effects.

[0110] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

[0111] The above-described embodiments merely represent several implementation methods of the present application. 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 a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
