[0050] A. First direction; B. Second direction. Detailed Implementation

[0051] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0052] In this disclosure, unless otherwise stated, directional terms such as "first direction" refer to the axial direction of the shaft, and "second direction" refers to the radial direction of the shaft. For details, please refer to [reference needed]. Figure 1 As shown; it should be noted that, Figure 1 The second direction shown in the illustration is merely an example of the radial direction of the axis of rotation. The directional terms used, such as "inner" and "outer," refer to the inner and outer parts of the specific structural outline. The terms used, such as "first" and "second," are only used to distinguish one element from another and do not have any order or importance. In addition, "multiple" in this application refers to two or more and includes two.

[0053] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0054] Reference Figures 1 to 8 As shown, this disclosure provides a transmission mechanism 10, which includes a drive input structure 1, a transmission member 2, and a limiting member 3. The drive input structure 1 includes an input part 11, a connecting part 12, and an output part 13. The connecting part 12 connects the input part 11 and the output part 13. The input part 11 is used to input external power. One of the output part 13 and the transmission member 2 includes a rotating shaft 131, and the other includes a rotating hole 21. The rotating shaft 131 is rotatably disposed within the rotating hole 21. The limiting member 3 can restrict the movement of the rotating shaft 131 relative to the rotating hole 21 in a first direction A and a second direction B; wherein, the first direction A is the axial direction of the rotating shaft 131, and the second direction B is the radial direction of the rotating shaft 131.

[0055] In the above technical solution, external power is received by the input part 11 of the drive input structure 1 and transmitted to the output part 13 via the connecting part 12. Then, through the cooperative design of the rotating shaft 131 and the rotating hole 21, the power is transmitted to the transmission member 2, which can move under the drive of the drive input structure 1. By setting the limiting member 3, the axial and radial movement of the rotating shaft 131 relative to the rotating hole 21 is restricted, thereby limiting the transmission member 2 from lateral movement and torsion relative to the drive input structure 1, ensuring effective power transmission.

[0056] In specific application scenarios, the aforementioned transmission component 2 can be connected to a connecting rod (not shown), and the connecting rod can be connected to multiple swing blades (not shown) to drive the swing blades to swing. By setting the aforementioned limiting component 3, the limiting component 3 can effectively limit the shaking of the swing blades by restricting the axial and radial movement of the shaft 131 relative to the rotating hole 21, thereby ensuring the accuracy of the swing blade deflection angle.

[0057] Additionally, it should be noted that the aforementioned drive input structure 1 can be constructed as a crankshaft structure. The input part 11 can be the main journal of the crankshaft structure, the output part 13 can be the connecting rod journal of the crankshaft structure, and the connecting part 12 can be the crank arm of the crankshaft structure. The length of the crank arm determines the eccentricity, that is, the offset of the connecting rod journal relative to the main journal.

[0058] Optionally, refer to Figure 1 , Figure 4 as well as Figure 5 As shown, the limiting member 3 includes a limiting member body 30, a first limiting part 31, and a second limiting part 32. The first limiting part 31 and the second limiting part 32 are disposed on the limiting member body 30. The first limiting part 31 can restrict the limiting member 3 from moving relative to the output part 13 in the first direction A and the second direction B. The limiting member body 30 can restrict the transmission member 2 from moving relative to the limiting member 3 in the first direction A, and the second limiting part 32 can restrict the transmission member 2 from moving relative to the limiting member 3 in the second direction B.

[0059] In this embodiment, by providing the first limiting part 31, the movement of the limiting member 3 relative to the drive input structure 1 in the first direction A and the second direction B can be restricted. By providing the limiting member body 30 and the second limiting part 32, the movement of the limiting member 3 relative to the transmission member 2 in the first direction A and the second direction B can be restricted. In other words, by providing the limiting member 3, the movement of the transmission member 2 relative to the drive input structure 1 in the first direction A and the second direction B can be restricted.

[0060] The first limiting part 31 and the second limiting part 32 described above can be constructed in any suitable shape and structure, and this disclosure does not limit them. In addition, the limiting member body 30, the first limiting part 31 and the second limiting part 32 can be constructed as an integral structure, which is convenient for processing and molding.

[0061] In one implementation, reference Figure 2 , Figure 3 as well as Figure 8 As shown, the output unit 13 includes a rotating shaft 131, which includes a rotating section 1311 and a limiting section 1312 connected to each other in the first direction A. The rotating section 1311 is rotatably disposed in the rotating hole 21, and the limiting section 1312 extends out of the rotating hole 21 and is limited and engaged with the first limiting part 31 to restrict the movement of the limiting member 3 relative to the rotating shaft 131 in the first direction A and the second direction B.

[0062] In this embodiment, the rotating shaft 131 includes a rotating section 1311 and a limiting section 1312, which are connected in the first direction A. The rotating section 1311 is rotatably disposed within the rotating hole 21, while the limiting section 1312 extends out of the rotating hole 21 and engages with the first limiting part 31. This design allows the rotating shaft 131 to maintain its rotational function while effectively limiting the movement of the limiting member 3 relative to the rotating shaft 131 in the first direction A and the second direction B. This means that even if the rotating shaft 131 is rotating, the limiting member 3 will not undergo unnecessary displacement in the first direction A and the second direction B. In addition, since the position of the limiting member 3 relative to the rotating shaft 131 is effectively fixed, the stability of power transmission is ensured.

[0063] In one implementation, reference Figures 3 to 5 ,as well as Figure 8 As shown, the limiting member body 30 includes a limiting sleeve, a first limiting part 31 is disposed on the inner wall of the limiting sleeve, and one of the inner wall of the limiting sleeve and the outer wall of the limiting section 1312 is provided with at least one snap-fit ​​groove 100, and the other is provided with at least one snap-fit ​​block 200. The snap-fit ​​block 200 is used to snap into the snap-fit ​​groove 100 to restrict the movement of the limiting sleeve relative to the rotating shaft 131 in the first direction A and the second direction B, and the limiting sleeve can abut against the transmission member 2 in the first direction A.

[0064] In this embodiment, by providing at least one snap-fit ​​groove 100 on one of the inner wall of the limiting sleeve and at least one snap-fit ​​block 200 on the other, and by engaging with the snap-fit ​​groove 100, the movement of the limiting sleeve relative to the rotating shaft 131 in the first direction A and the second direction B can be restricted, thus preventing the two from moving sideways.

[0065] Reference Figure 3As shown, there are multiple snap-fit ​​slots 100, each including two slot groups 1001, which are opposite to each other and spaced apart in the second direction B. There are multiple snap-fit ​​blocks 200, each including two block groups 2001 that correspond one-to-one with the two slot groups 1001, which are opposite to each other in the second direction B. The multiple snap-fit ​​slots 100 in the slot group 1001 are spaced apart in pairs in the first direction A, and each snap-fit ​​slot 100 is recessed in the second direction B. The multiple snap-fit ​​blocks 200 in the block group 2001 are spaced apart in pairs in the first direction A, and each snap-fit ​​block 200 is protruding in the second direction B.

[0066] In this embodiment, two slot groups 1001 are arranged opposite to each other and spaced apart in the second direction B, while two locking block groups 2001 are arranged opposite to each other in the second direction B and correspond one-to-one with the slot groups 1001, further enhancing the limiting effect in the first direction A and the second direction B. Each locking slot 100 is recessed in the second direction B, while each locking block 200 is protruding in the second direction B. This concave-convex fit effectively increases the friction between the mating structures and provides additional mechanical locking, reducing the possibility of the limiting member 3 accidentally disengaging from the rotating shaft 131.

[0067] In addition, the limiting member 3 can rotate relative to the limiting segment 1312 and has a locked position and an unlocked position; in the unlocked position, the limiting segment 1312 can disengage from the limiting sleeve; in the locked position, the locking block 200 is at least partially engaged in the corresponding locking groove 100.

[0068] Specifically, refer to Figure 2 As shown, the limiting sleeve is fitted onto the limiting section 1312, but the locking block 200 is not engaged in the locking groove 100, and the limiting member 3 is in the unlocked position. By pulling the limiting sleeve along the first direction A, the limiting member 3 can be disengaged from the rotating shaft 131. By rotating the limiting member 3, the locking block 200 can be engaged at least partially in the corresponding locking groove 100, realizing the locking connection between the limiting member 3 and the rotating shaft 131 in the first direction A and the second direction B, that is, the limiting member 3 is in the locked position.

[0069] In another embodiment, the limiting member body 30 includes a limiting sleeve, and the first limiting portion 31 includes an internal thread (not shown) on the inner wall of the limiting sleeve. The outer wall of the limiting segment 1312 is provided with an external thread (not shown). The external thread can form a threaded engagement with the internal thread to restrict the movement of the limiting sleeve relative to the rotating shaft 131 in the first direction A and the second direction B. The engagement of the external and internal threads can be regarded as a special engagement of the snap-fit ​​block 200 and the snap-fit ​​groove 100. That is, the movement of the limiting member 3 and the rotating shaft 131 in the first direction A and the second direction B is realized through the threaded engagement. However, this disclosure does not limit the specific structure of the limiting member body 30 and the first limiting portion 31.

[0070] Optionally, refer to Figure 3 , Figure 6 as well as Figure 7 As shown, the transmission component 2 includes a limiting hole 22 and a rotating hole 21. The limiting hole 22 and the rotating hole 21 are interconnected to form a stepped hole. The diameter of the limiting hole 22 is larger than the diameter of the rotating hole 21 to form a first stepped surface 23 at the connection. The output part 13 also includes a journal 132, which connects the connecting part 12 and the rotating section 1311. The radial dimension of the journal 132 is larger than the radial dimension of the rotating shaft 131 to form a second stepped surface 133. That is, the journal 132 and the rotating shaft 131 are configured as a stepped shaft.

[0071] The rotating section 1311 is rotatably disposed within the rotating hole 21, and at least a portion of the limiting member 3 and the limiting section 1312 are disposed within the limiting hole 22. The limiting member body 30 can limit the first step surface 23 in the first direction A, and the second step surface 133 can limit the outer surface of the transmission member 2 in the first direction A.

[0072] In this embodiment, the limiting effect of the first step surface 23 and the second step surface 133 ensures the stability of the transmission component 2 in the first direction A, preventing it from shifting in the first direction A and improving stability and transmission accuracy. Secondly, the first step surface 23 and the second step surface 133 provide clear limiting interfaces for assembly, making alignment and fixation easier during installation and reducing the possibility of assembly errors. Furthermore, the design of the limiting hole 22 and the rotating hole 21 allows the rotating section 1311 to rotate smoothly, while the limiting component 3 and the limiting section 1312 are partially disposed within the limiting hole 22. This facilitates the installation of the limiting component 3 while also effectively utilizing space and improving the compactness of the structural design.

[0073] In other implementations, refer to Figure 5 and Figure 6As shown, one of the second limiting part 32 and the first step surface 23 includes at least one limiting block 300, and the other includes a limiting groove 400. The limiting block 300 is limitedly disposed in the limiting groove 400 in the second direction B. The limiting block 300 and the limiting groove 400 are configured such that the limiting block 300 can slide in the limiting groove 400 during the rotation of the transmission member 2 relative to the rotating shaft 131.

[0074] In this embodiment, the cooperative design of the limiting block 300 and the limiting groove 400 ensures effective limiting between the limiting member 3 and the transmission member 2 in the second direction B. Combined with the aforementioned limiting design of the first step surface 23 and the second step surface 133, it ensures effective limiting between the limiting member 3 and the transmission member 2 in the first direction A and the second direction B. Furthermore, the cooperative structure of the limiting block 300 and the limiting groove 400 allows the limiting block 300 to slide within the limiting groove 400 during the rotation of the transmission member 2 relative to the rotating shaft 131. This design maintains the necessary limiting function while allowing a certain degree of relative movement, ensuring the flexibility and adaptability of the structural design.

[0075] In one embodiment, the limiting groove 400 described above can be constructed as an arc-shaped groove, the center of which coincides with the axis of the rotating shaft 131; the limiting block 300 is constructed as an arc-shaped block, the center of which coincides with the axis of the rotating shaft 131.

[0076] Since both the limiting groove 400 and the limiting block 300 are designed in an arc shape with the rotating shaft 131 as the center, this design can ensure that the limiting block 300 always moves along the trajectory of the limiting groove 400 during rotation. This ensures that the normal rotation of the transmission component 2 relative to the drive input structure 1 is not affected while limiting, and can reduce unnecessary vibration and wear.

[0077] For example, the aforementioned limiting groove 400 can be constructed as a circular groove, and the aforementioned limiting block 300 can be configured as an arc-shaped block and multiple blocks can be configured at intervals.

[0078] Optionally, refer to Figure 5 and Figure 6 As shown, the limiting component body 30 includes a limiting sleeve, a limiting groove 400 recessed on the end face of the limiting sleeve, and a limiting block 300 protruding on the first step surface 23.

[0079] By recessing the limiting groove 400 onto the end face of the limiting sleeve, and simultaneously allowing the limiting block 300 to protrude from the first stepped surface 23, the limiting block 300 can be precisely embedded within the limiting groove 400, thereby providing accurate mechanical positioning and facilitating assembly. Furthermore, the limiting groove 400 and the limiting block 300 fully utilize the layout space, enhancing the compactness of the structural design.

[0080] In addition, the limiting block 300 is protruding in the first direction A, and the limiting groove 400 is recessed in the first direction A; wherein, the size of the limiting block 300 in the first direction A is larger than the size of the limiting groove 400 in the first direction A.

[0081] In this embodiment, by making the dimension of the limiting block 300 in the first direction A larger than the dimension of the limiting groove 400 in the first direction A, the first step surface 23 will not directly contact the end face of the limiting sleeve, thereby reducing the contact area and avoiding excessive contact area from affecting the rotation of the transmission component 2 or generating abnormal noise.

[0082] Reference Figure 1 As shown, the limiting member 3 also includes a third limiting part 33, which is disposed on the limiting member body 30; the transmission member 2 includes a slot 600, and a hook 500 is engaged in the slot 600; the hook 500 and the slot 600 are configured such that during the rotation of the transmission member 2 relative to the output part 13, the hook 500 is restricted to move along the first direction A, and the hook 500 can slide in the slot 600.

[0083] In this embodiment, the design of the hook 500 and the slot 600 provides a secure connection in the first direction A, ensuring a stable connection between the transmission member 2 and the output part 13 and preventing them from loosening or separating. Furthermore, the hook 500 can slide within the slot 600, ensuring that it does not affect the rotation of the transmission member 2 relative to the output part 13.

[0084] Specifically, refer to Figure 1 and Figure 7 As shown, the hook 500 includes a hook arm 5001 and a hook head 5002. One end of the hook arm 5001 is connected to the limiting member body 30, and the other end is connected to the hook head 5002. A groove 600 is formed on the outer surface of the transmission member 2. The hook head 5002 is slidably disposed in the groove 600, and a gap is provided between the hook arm 5001 and the outer surface of the transmission member 2.

[0085] A gap is provided between the hook arm 5001 and the outer surface of the transmission component 2, which effectively reduces direct contact between the two, thereby reducing friction and wear. Secondly, even with the gap, the hook head 5002 remains firmly held in the slot 600, ensuring safety and stability under normal operating conditions. Furthermore, this disclosure does not limit the specific structure of the hook 500; it can be constructed in any suitable shape and structure.

[0086] Regarding the formation of the aforementioned gaps, refer to Figure 7As shown, the slot 600 can be formed on the outer surface of the transmission member 2. The outer surface of the transmission member 2 includes a first circumferential side surface 24 and a second circumferential side surface 25. The slot 600 is disposed between the first circumferential side surface 24 and the second circumferential side surface 25, and the diameter of the first circumferential side surface 24 is smaller than the diameter of the second circumferential side surface 25. The first circumferential side surface 24 is spaced apart from the hook arm 5001 to form a gap.

[0087] Optionally, the slot 600 is constructed as an arc-shaped slot, with the center of the arc-shaped slot coinciding with the axis of the rotating shaft 131. This ensures that the normal rotation of the transmission component 2 relative to the drive input structure 1 is not affected while limiting the movement, and also reduces unnecessary vibration and wear.

[0088] For example, the aforementioned slot 600 can be constructed as a circular slot, and the aforementioned hook 500 can be set as two, with the two hooks 500 being arranged opposite each other in the second direction B.

[0089] This disclosure also provides a swing assembly, which includes a power component (not shown), a connecting rod (not shown), at least one swing blade (not shown), and the aforementioned transmission mechanism 10; the power component is driven to the input part 11, the transmission component 2 is driven to the connecting rod, and the connecting rod is driven to the swing blade to drive the swing blade to swing.

[0090] In the above technical solution, by setting the limiting member 3, the limiting member 3 can effectively limit the shaking of the swing blades by restricting the axial and radial movement of the shaft 131 relative to the rotating hole 21, thereby ensuring the accuracy of the swing blade deflection angle.

[0091] This disclosure also provides an air supply device, which includes a device housing (not shown) and the aforementioned swing assembly; the device housing has an air outlet (not shown), and the swing assembly is disposed at the air outlet.

[0092] The aforementioned air supply equipment may include any suitable electrical appliance capable of supplying air, such as air conditioning equipment, heaters, and fans, etc., which are not limited in this disclosure.

[0093] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of this disclosure. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the following claims.

[0094] It should be understood that this disclosure is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this disclosure is limited only by the appended claims.
