Description

Technical Field

[0001] This application relates to the field of small household appliances, and in particular to a support device and an air outlet device. Background Technology

[0002] With social development and improved living standards, people's lifestyles have become more diverse, and more and more people are participating in outdoor sports such as camping and picnics. Since outdoor sports are often carried out in sunny and hot weather, people's demand for outdoor fans that can be used in outdoor environments is increasing day by day.

[0003] Because outdoor fans are used in complex and ever-changing external environments, they are often supported by brackets on uneven beaches and grass. However, due to structural defects in the brackets, height adjustment and disassembly are quite complicated, which brings inconvenience to the use of outdoor fans, affects the user experience, and is not conducive to the further promotion of outdoor fans. Summary of the Invention

[0004] Therefore, it is necessary to provide a support device and air outlet equipment to address the inconvenience of height adjustment and disassembly / removal of outdoor fans.

[0005] A support device includes a mounting mechanism and a plurality of telescopic rods, one end of each telescopic rod being rotatably connected to the mounting mechanism, the mounting mechanism comprising:

[0006] Mounting base, one end of the telescopic rod is rotatably mounted on one axial end of the mounting base;

[0007] The limiting component includes a first limiting part and a second limiting part that are connected to each other.

[0009] The quick-release component has one end rotatably fitted onto the first limiting part, and the other end is provided with a quick-release latch for connecting to the supported structure.

[0010] The lever can be controlled to rotate relative to the mounting base to drive the limiting member or the quick-release member to rotate, and during the rotation of the limiting member, one end of the telescopic rod can abut against the second limiting part or separate from the second limiting part.

[0011] In one embodiment, the mounting mechanism further includes a first reset member located within the mounting base and abutting against the quick-release member.

[0020] In one embodiment, the second limiting part has a limiting bottom surface and a limiting side surface surrounding the limiting bottom surface in the circumferential direction, and the limiting side surface has a limiting groove communicating with the limiting bottom surface.

[0021] When the telescopic rod is at its minimum length, one end of the telescopic rod abuts against the limiting bottom surface;

[0022] When the telescopic rod is at its maximum length, one end of the telescopic rod abuts against the limiting side.

[0023] When the telescopic rod extends from its minimum length to its maximum length, one end of the telescopic rod corresponds to and is spaced apart from the wall of the limiting groove in the radial direction of the limiting member, and abuts against the wall of the limiting groove in the circumferential direction of the limiting member.

[0028] The telescopic component is housed within the telescopic outer rod, with one end confined to the upper connector and the other end confined to the telescopic inner rod. The telescopic component is used to apply a force to the telescopic outer rod and the telescopic inner rod to move them away from each other.

[0029] In one embodiment, the telescopic rod further includes a limiting unit, which is coupled to one end of the telescopic inner rod inserted into the telescopic outer rod, and the telescopic member abuts against the limiting unit.

[0030] In one embodiment, the second limiting portion is provided with a hook.

[0031] In one embodiment, the support device further includes a chassis, and the end of the telescopic rod away from the mounting base is rotatably mounted on the chassis.

[0032] In one embodiment, the support device further includes a plurality of support rods, one end of each support rod being rotatably mounted to the chassis.

[0034] The aforementioned support device allows for the assembly and disassembly of the supported device and adjustment of its support height via a lever. This solves the problems of difficulty in adjusting the support height and difficulty in assembling and disassembling the supported device, achieving an integrated design of the assembly and disassembly structure and the support height adjustment structure. This optimizes the structure of the support device and reduces its size. Attached Figure Description

[0049] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0050] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0051] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0052] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0053] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0054] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0055] See Figure 1 and Figure 2 One embodiment of this application provides a support device 100 for supporting a structure on the ground, a tabletop, or other support surface.

[0056] The structure of the support device 100 in this application will be described below using an air outlet device as an example of the supported structure. This embodiment is only used as an example and does not limit the technical scope of this application. It is understood that in other embodiments, the supported structure may also be a lamp or other device, which is not limited here.

[0057] Please combine Figure 3 As shown, the bottom of the air outlet device has a mounting base 200, which is a cylindrical structure with one open end. It includes a top wall and a side wall extending in the same direction from the edge of the top wall. The inner surface of the side wall is provided with a quick-release locking groove 210 and an anti-rotation groove 230 for engaging the support device 100. Specifically, in the following embodiments, the side wall of the mounting base has two quick-release locking grooves 210, which are arranged opposite to each other in a radial direction of the mounting base 200. The anti-rotation groove 230 is located between the two quick-release locking grooves 210, and its cross-section is approximately trapezoidal.

[0058] Please continue reading. Figure 1 and Figure 2 The support device 100 includes a mounting mechanism 120 and multiple telescopic rods 140. The mounting mechanism 120 is used to connect to the air outlet device. One end of each telescopic rod 140 is connected to the mounting mechanism 120, and each telescopic rod 140 can extend or retract along its own length, thereby adjusting the support height of the support device 100. In the following embodiments, the support device 100 includes three telescopic rods 140, which are spaced apart along the circumferential direction of the mounting mechanism 120. It is understood that the number of telescopic rods 140 is not limited to this, and can also be four, five, or more, to meet different support needs.

[0059] Please see Figure 4 , Figure 5 as well as Figure 6The installation mechanism 120 includes a mounting base 121, a limiting member 122, a lever 124, and a quick-release member 125. One end of each telescopic rod 140 is rotatably mounted to an axial end of the mounting base 121. The limiting member 122 includes a first limiting part 1221 and a second limiting part 1223. The first limiting part 1221 is inserted into the mounting base 121 along the axial direction, and the second limiting part 1223 protrudes from the axial end of the mounting base 121 connecting the telescopic rod 140 along the axial direction. One end of the lever 124 is rotatably fitted onto the first limiting part 1221, and the other end extends out of the mounting base 121 along the radial direction. One end of the quick-release member 125 is rotatably fitted onto the first limiting part 1221, and the other end is provided with a quick-release locking part 1252c for locking the air outlet device. The lever 124 can be controlled to rotate relative to the mounting base 121 to drive the limiting member 122 or the quick-release member 125 to rotate. During the rotation of the limiting member 122, one end of each telescopic rod 140 can abut against the second limiting part 1223 or separate from the second limiting part 1223.

[0060] Thus, by rotating the dial 124, the limiting member 122 can be rotated to engage or disengage with the air outlet device, and it can also be rotated to abut or disengage with the telescopic rod 140. When the telescopic rod 140 abuts against the limiting member 122, the telescopic rod 140 maintains a fixed length under the restraint of the limiting member 122. When the telescopic rod 140 disengages from the limiting member 122, the telescopic rod 140 can extend or retract to adjust its length.

[0061] Therefore, the aforementioned support device 100 can realize the disassembly and assembly of the air outlet device and the adjustment of the support height through the lever 124. At the same time, it solves the problems that the support height of the support device 100 is not easy to adjust and the air outlet device is not easy to disassemble and assemble. It realizes the integrated setting of the disassembly and assembly structure of the air outlet device and the support height adjustment structure, optimizes the structure of the support device 100, and reduces the volume of the support device 100.

[0062] In some embodiments, the mounting mechanism 120 further includes a first reset member 126, a second reset member 127, and a spring plate 123. The first reset member 126 is located within the mounting base 121 and abuts against the quick-release member 125. The first reset member 126 is capable of recoverable deformation under external force, which applies a force against the lever 124 to the quick-release member 125, thereby causing the quick-release member 125 to automatically return to its initial position after the force of the lever 124 disappears. The second reset member 127 is located within the mounting base 121. The spring plate 123 is sleeved and fixed to the second limiting part 1223. The second reset member 127 abuts against the spring plate 123, thereby applying a force against the lever 124 to the limiting member 122 through the spring plate 123, thereby causing the limiting member 122 to automatically return to its initial position after the force of the lever 124 disappears.

[0063] Please combine Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the mounting base 121 is generally a hollow cylindrical structure with one end open, including a mounting base bottom wall and a mounting base side wall extending vertically in the same direction from the edge of the mounting base bottom wall. The mounting base side wall surrounds the mounting base bottom wall in the circumferential direction to form a mounting cavity with one end open.

[0064] A connecting hole 1211 is provided at the center of the bottom wall of the mounting base, which connects to the mounting cavity. The first limiting part 1221 of the limiting member 122 can be inserted into the mounting cavity through the connecting hole 1211. Three telescopic rod mounting parts 1212 are protruding on the side surface of the bottom wall of the mounting base facing away from the mounting cavity. All telescopic rod mounting parts 1212 are circumferentially arranged around the central connecting hole 1211, and one end of each telescopic rod 140 is rotatably mounted to one telescopic rod mounting part 1212. It can be understood that the number of telescopic rod mounting parts 1212 is not limited to this, and the number of telescopic rod mounting parts 1212 is the same as the number of telescopic rods 140. Therefore, each telescopic rod 140 is connected to the mounting base 121 through one telescopic rod mounting part 1212.

[0065] A circumferentially extending arc-shaped connecting groove 1213 is provided on the side wall of the mounting base, through which one end of the lever 124 extends out of the mounting cavity. A partition 1214 protrudes from the inner surface of the side of the mounting base 121 where the arc-shaped connecting groove 1213 is located, and is situated near the bottom wall of the mounting base. The partition 1214 separates the quick-release piece 125 and the spring plate 123 and limits their rotation angle. A reset member abutment 1215 protrudes from the inner surface of the other side wall of the mounting base away from the partition 1214, and is used to abut against the first reset member 126 and the second reset member 127. Furthermore, the shape of the cross section of the reset member abutment portion 1215 perpendicular to the axial direction of the mounting base 121 is a trapezoid that matches the shape of the anti-rotation groove 230 on the mating base 200. Therefore, one end of the reset member abutment portion 1215 away from the bottom wall of the mounting base can be inserted into the anti-rotation groove 230, thereby preventing the air outlet device from rotating relative to the mounting base 121.

[0066] Please combine Figure 5 , Figure 6 and Figure 9As shown, the limiting member 122 is generally a hollow, rotating structure. The outer diameter of the first limiting part 1221 matches the diameter of the connecting hole 1211 on the mounting base 121, so that it passes through the connecting hole 1211 along the axial direction of the mounting base 121 and is inserted into the mounting cavity of the mounting base 121, and can rotate relative to the mounting base 121. The outer diameter of the second limiting part 1223 is larger than the outer diameter of the first limiting part 1221 and the diameter of the connecting hole 1211, so that it abuts against the side of the bottom wall of the mounting base facing away from the mounting cavity.

[0067] Furthermore, the second limiting part 1223 has a limiting bottom surface 1223a facing away from the first limiting part 1221 and a limiting side surface 1223b surrounding the limiting bottom surface 1223a circumferentially. The limiting side surface 1223b has three limiting grooves 1223c communicating with the limiting bottom surface 1223a, and all the limiting grooves 1223c are arranged at intervals along the circumference of the second limiting part 1223. Thus, the telescopic rod 140 can abut against the limiting bottom surface 1223a, the limiting side surface 1223b, or the limiting grooves 1223c, thereby switching between different lengths. It is understood that the number of limiting grooves 1223c is not limited to this; the number of limiting grooves 1223c is the same as the number of telescopic rods 140 and is set according to the number of telescopic rods 140.

[0068] In some embodiments, a hook 1225 is also provided at the center of the limiting bottom surface 1223a of the second limiting portion 1223, so the support device 100 can be suspended upside down in the tent or other locations through the hook 1225.

[0069] Please combine Figure 5 , Figure 6 and Figure 10 As shown, the spring plate 123 includes a spring plate body 1232, a first spring plate abutting part 1234, and a second spring plate abutting part 1236. The spring plate body 1232 has an annular structure, is sleeved on the second limiting part 1223, and is fixed to the second limiting part 1223 by means of bonding or other methods, so the spring plate 123 rotates synchronously with the limiting part 122. The first spring plate abutting part 1234 and the second spring plate abutting part 1236 are provided at intervals along the circumference of the spring plate body 1232 and protrude from the outer circular surface of the spring plate body 1232. The first spring plate abutting part 1234 is used to abut against the partition part 1214 and the lever plate 124 in the circumference of the mounting base 121, and the second spring plate abutting part 1236 is used to abut against the second reset member 127 in the circumference of the mounting base 121.

[0070] Please combine Figure 5 , Figure 6 and Figure 11As shown, the toggle 124 includes a toggle connecting part 1241, a toggle lever 1243, and a toggle part 1245. The toggle connecting part 1241 is annular, sleeved on the second limiting part 1223, and abuts against the spring plate body 1232. One end of the toggle lever 1243 is connected to the toggle connecting part 1241, and the other end of the toggle lever 1243 extends radially outward along the mounting base 121. The toggle part 1245 is an arc-shaped strip structure that extends circumferentially along the mounting base 121. The toggle part 1245 extends outward through an arc-shaped connecting groove 1213 opened on the side wall of the mounting base, and the middle position of the toggle part 1245 protrudes outward. In this way, the user can toggle the toggle 124 to different angles through the toggle part 1245. During the rotation of the toggle 124, the toggle lever 1243 can push the quick-release piece 125 or the spring plate 123 to rotate.

[0071] Please combine Figure 5 , Figure 6 and Figure 12 As shown, the quick-release component 125 includes a quick-release body 1252, a first quick-release abutment 1254, and a second quick-release abutment 1256. The quick-release body 1252 includes a central connecting portion 1252a and two connecting arms 1252b. The central connecting portion 1252a has a ring-shaped structure and is rotatably fitted onto the first limiting portion 1221 of the limiting component 122 and located above the spring plate 123. The two connecting arms 1252b are respectively connected to opposite sides of the central connecting portion 1252a in a radial direction, and one end of each connecting arm 1252b is connected to the central connecting portion 1252a, while the other end of the connecting arm 1252b bends and extends away from the bottom wall of the mounting base. The end of each connecting arm 1252b away from the central connecting portion 1252a forms the aforementioned quick-release latching portion 1252c.

[0072] One end of the first quick-release abutment 1254 is connected to the intermediate connecting part 1252a and located between the two connecting arms 1252b. The other end of the first quick-release abutment 1254 extends toward the bottom wall of the mounting base and is used to abut against the partition 1214 and the lever 124 inside the mounting base 121 in the circumferential direction. One end of the second quick-release abutment 1256 is connected to one of the connecting arms 1252b and the other end extends toward the bottom wall of the mounting base and is used to abut against the first reset member 126 in the circumferential direction of the mounting base 121.

[0073] like Figure 6As shown, both the first reset member 126 and the second reset member 127 are springs. One end of the first reset member 126 is connected to the second quick-release abutment portion 1256 of the quick-release member 125, and the other end of the first reset member 126 faces the reset member abutment portion 1215 of the mounting base 121. When the first reset member 126 is in a compressed state, it abuts against one side of the reset member abutment portion 1215, thereby applying a pushing force to the quick-release member 125 toward the partition portion 1214. One end of the second reset member 127 is connected to the second spring plate abutment portion 1236 of the spring plate 123, and the other end of the second reset member 127 faces the reset member abutment portion 1215 of the mounting base 121. When the second reset member 127 is in a compressed state, it abuts against the other side of the reset member abutment portion 1215, thereby applying a pushing force to the spring plate 123 toward the partition portion 1214.

[0074] Please continue reading. Figure 4 , Figure 5 as well as Figure 6 In some embodiments, the mounting mechanism 120 further includes an inner cover plate 128 and a bushing 129. The inner cover plate 128 is generally disc-shaped and is fitted onto the first limiting portion 1221 of the limiting member 122 and abuts against the quick-release member 125. The edge of the inner cover plate 128 has a communicating groove through which the separating portion 1214 and the connecting arm 1252b of the quick-release member 125 can pass. The bushing 129 is axially inserted into the first limiting portion 1221 and abuts against the inner cover plate 128. Fasteners such as screws can pass through the bushing 129 and the inner cover plate 128 in sequence and extend into the first limiting portion 1221, thereby locking the inner cover plate 128, quick-release member 125, lever 124, spring plate 123, limiting member 122, and mounting base 121 together to prevent these components from coming apart.

[0075] like Figure 6 As shown, when the spring plate 123, the lever plate 124, the quick-release member 125, the limiting member 122, and the mounting base 121 are connected to each other, in the circumferential direction of the mounting base 121, the first quick-release abutment portion 1254 of the quick-release member 125 and the first spring plate abutment portion 1234 of the spring plate 123 abut against the opposite sides of the partition portion 1214 of the mounting base 121, respectively. The second quick-release abutment portion 1256 of the quick-release member 125 is located on the side of the first quick-release abutment portion 1254 away from the partition portion 1214, and the second spring plate abutment portion 1236 of the spring plate 123 is located on the side of the first spring plate abutment portion 1234 away from the partition portion 1214, and is located below the connecting arm 1252b of the quick-release member 125 where the second quick-release abutment portion 1256 is not connected. The separator 1214 can limit the angle of the quick-release piece 125 and the spring plate 123, determine their starting positions, and separate them to ensure that one of them will not move due to the rotation of the other.

[0076] Please refer to it again. Figure 4 and Figure 5 The telescopic rod 140 includes a telescopic outer rod 141, an upper connector 142, a telescopic inner rod 143, and a telescopic member 144. The telescopic outer rod 141 has a hollow rod-like structure. One end of the upper connector 142 is fixed to the outside of one end of the telescopic outer rod 141, and the other end of the upper connector 142 is rotatably connected to the telescopic rod mounting portion 1212 of the mounting base 121. The telescopic inner rod 143 has a hollow rod-like structure, and its outer diameter matches the inner diameter of the telescopic outer rod 141, thus being inserted into the end of the telescopic outer rod 141 away from the upper connector 142. The telescopic member 144 is housed within the telescopic outer rod 141. One end of the telescopic member 144 abuts against the upper connector 142, and the other end of the telescopic member 144 is confined within the telescopic inner rod 143. The telescopic rod 140 is used to apply a force to the telescopic outer rod 141 and the telescopic inner rod 143, causing them to move away from each other, thereby changing the length of the telescopic rod 140.

[0077] In some embodiments, the telescopic rod 140 further includes a limiting unit, which is connected to one end of the inner telescopic rod 143 inserted into the outer telescopic rod 141, and the telescopic member 144 abuts against the limiting unit.

[0078] Specifically, the limiting unit includes an outer limiting rod 145 and an inner limiting rod 146. The inner limiting rod 146 includes a first limiting segment 1461, a second limiting segment 1463, and a third limiting segment 1465 connected sequentially along the axial direction. The second limiting segment 1463 is connected between the first limiting segment 1461 and the third limiting segment 1465, and the outer diameter of the second limiting segment 1463 is larger than that of the first limiting segment 1461 and the third limiting segment 1465. The first limiting segment 1461 is inserted into one end of the telescopic inner rod 143, which is inserted into one end of the telescopic outer rod 141. The second limiting segment 1463 abuts against the end face of the telescopic inner rod 143. One end of the telescopic member 144 is sleeved outside the third limiting segment 1465 and abuts against the second limiting segment 1463 in the axial direction. The outer limiting rod 145 is inserted at the end of the telescopic outer rod 141 away from the upper connector 142 and abuts against the side of the second limiting section 1463 opposite to the third limiting section 1465 to prevent the telescopic member 144 from disengaging from the telescopic outer rod 141.

[0079] In some embodiments, the telescopic rod 140 further includes a lower connector 147, which is installed at the end of the telescopic inner rod 143 extending out of the telescopic outer rod 141. The support device 100 also includes a chassis 160 and multiple support rods 180. The chassis 160 has a circular structure, and the lower connector 147 of the telescopic rod 140 is rotatably mounted on the chassis 160. One end of each support rod 180 is rotatably mounted on the chassis 160. Thus, one end of the telescopic rod 140 is supported on the chassis 160, and the chassis 160 is supported on the mounting surface by the support rods 180. When facing uneven mounting surfaces such as sand or grass, the support stability can be improved by adjusting the opening and closing angle of the support rods 180.

[0080] The disassembly methods for the aforementioned support device 100 and air outlet device are as follows:

[0081] In the initial state, the first quick-release abutment portion 1254 of the quick-release component 125 abuts against the partition portion 1214 of the mounting base 121 in the circumferential direction, the quick-release snap-fit ​​portion 1252 of the quick-release component 125 snaps into the quick-release snap-fit ​​groove 210 of the mating base 200, and the reset abutment portion 1215 of the mounting base 121 is inserted into the anti-rotation groove 230 of the mating base 200.

[0082] The user rotates the lever 124 around the limiting member 122. The lever 124 pushes the first quick-release abutment part 1254 to rotate around the limiting member 122, thereby causing the second quick-release abutment part 1256 to rotate synchronously to compress the first reset member 126. The quick-release latching part 1252c of the quick-release member 125 rotates synchronously and disengages from the quick-release latching groove 210. Therefore, the mating seat 200 can be removed from the mounting seat 121. Finally, the lever 124 is released. The second quick-release abutment part 1256 rotates in the opposite direction under the push of the restoring force of the second reset member 127, thereby causing the first quick-release abutment part 1254 to rotate in the opposite direction and abut against the partition part 1214 again.

[0083] The support height adjustment method of the above-mentioned support device 100 is as follows:

[0084] When the telescopic rod 140 is at its minimum length, the inner telescopic rod 143, housed within the outer telescopic rod 141, reaches its maximum length. At this time, the upper connector 142 of the telescopic rod 140 abuts against the limiting bottom surface 1223a of the second limiting portion 1223 of the limiting member 122. Under the support of the limiting bottom surface 1223a, the telescopic member 144 within the telescopic rod 140 is in its maximum compressed state. Simultaneously, in the mounting base 121, the spring plate 123 is in its initial state, and the first spring plate abutting portion 1234 of the spring plate 123 abuts against the partition portion 1214 of the mounting base 121 in the circumferential direction.

[0085] When the user moves the lever 124 to rotate around the limiting member 122, the lever 1243 pushes the first spring plate abutment part 1234 to rotate around the limiting member 122. The second spring plate abutment part 1236 rotates synchronously to compress the second reset member 127. The limiting member 122 rotates synchronously with the spring plate 123, so that the limiting groove 1223c on the second limiting part 1223 aligns with the limiting member 122. At this time, the upper connector 142 loses the support of the limiting bottom surface 1223a. The telescopic outer rod 141 and the telescopic inner rod 143 move relative to each other under the drive of the telescopic member 144, so that the length of the telescopic rod 140 gradually extends. During the extension of the telescopic rod 140, one end of the upper connector 142 extends into the limiting groove 1223c. In the radial direction of the limiting member 122, there is a certain gap between the upper connector 142 and the groove wall of the limiting groove 1223c. In the circumferential direction of the limiting member 122, the upper connector 142 abuts against the groove wall of the limiting groove 1223c to prevent the limiting member 122 from rotating.

[0086] When the telescopic rod 140 is at its maximum length, the upper connector 142 completely disengages from the limiting groove 1223c and loses its circumferential limiting function. Therefore, the second reset member 127 returns to its initial state, thereby causing the second spring plate abutment part 1236 to rotate in the opposite direction. The first spring plate abutment part 1234 rotates synchronously and abuts against the partition part 1214 again. The limiting member 122 also rotates synchronously, causing the limiting groove 1223c to be misaligned with the upper connector 142. The upper connector 142 abuts against the limiting side 1223b of the second limiting part 1223.

[0087] When the height needs to be lowered, the lever 124 is turned again, and the limiting member 122 rotates so that the limiting groove 1223c aligns with the upper connector 142. The user can apply vertical downward pressure to the mounting base 121, and the telescopic member 144 inside the support rod 180 receives a component force compression. The telescopic inner rod 143 retracts into the telescopic outer rod 141, and the upper connector 142 disengages from the limiting groove 1223c. Therefore, the limiting member 122 rotates under the drive of the second reset member 127, causing the limiting groove 1223c to be misaligned with the upper connector 142. The upper connector 142 then abuts against the limiting bottom surface 1223a of the second limiting part 1223.

[0088] When the air outlet is used inside the tent, the telescopic rod 140 can be retracted to its lowest support height, and the support rod 180 can be rotated to fold inward toward the chassis 160. Then, the support device 100 is hung upside down by the hook on the first limiting member 122. The edge of the chassis 160 can abut against the inner top of the tent, thereby fixing it and preventing the air outlet from shaking inside the tent. Moreover, the upper joints 142 of the three telescopic rods 140 abut against the limiting bottom surface 1223a of the second limiting part 1223, thus preventing the mounting base 121 from sliding and ensuring the stability of the support device 100.

[0089] This application also provides an air outlet device, including the above-mentioned air outlet device and support device 100, wherein the air outlet device is detachably installed on the support device 100.

[0090] The aforementioned support device 100 and air outlet equipment can achieve height adjustment and air outlet installation by rotating the lever 124. Furthermore, the lever 124 automatically returns to its original position via the first reset member 126 and the second reset member 127, resulting in high adjustment efficiency and installation stability. Moreover, the inclusion of the telescopic rod 140, chassis 160, and support rod 180 allows for placement of the air outlet equipment in various scenarios, increasing its practicality.

[0091] 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.

[0092] 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.
