At least part of the second conical tooth portion is located in the receiving groove. The two racks are disposed opposite to each other on both sides of the receiving groove and respectively mesh with the second straight tooth portion and the third straight tooth portion.

[0016] Through the above design, the second straight tooth section and the third straight tooth section drive the gear and the cover plate to rotate, thereby realizing the overall oscillation of the fan body.

[0017] In one embodiment of the first aspect, the second transmission member further includes a handle portion rotatably disposed at one end of the connecting shaft.

[0047] 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.

[0048] 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.

[0049] Furthermore, where the term "and / or" appears, "and / or" merely describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship. Where the terms "first" and "second" appear, these terms are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. 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.

[0050] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0051] 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.

[0052] 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.

[0053] In related technologies, the left and right oscillation mechanism of some circulating fans is generally located inside the body and uses a direct drive or linkage gear drive. However, the direct drive motor may generate significant noise during operation, affecting the user experience. Furthermore, prolonged operation may cause the motor to overheat, affecting its lifespan and stability, resulting in uneven oscillation range or unstable speed. In the linkage gear drive method, the linkage and gears are prone to wear during prolonged use, leading to unstable oscillation or even jamming. Additionally, the linkage gear drive structure is relatively complex, requiring regular maintenance and lubrication, increasing user maintenance costs, and is also bulky in appearance. Moreover, neither of these methods can effectively control the oscillation of the circulating fan, making them unsuitable for applications that do not require left and right oscillation, and failing to meet diverse user needs.

[0054] See Figure 1 As shown, in order to improve the above problems, the embodiments of this application provide an oscillation control mechanism 100 to adjust the oscillation control of the circulating fan according to user needs, meet the fixed operation requirements of the non-oscillation circulating fan, and improve user experience and overall service life.

[0055] Specifically, the oscillation control mechanism 100 includes a drive member 110, a first transmission member 130, a second transmission member 140, and a working member 160. The first transmission member 130 is connected to the drive member 110, the second transmission member 140 can be controlled to connect or disconnect from the first transmission member 130, and the working member 160 is in transmission cooperation with the second transmission member 140 and can rotate under the drive of the second transmission member 140.

[0056] It should be noted that, for ease of understanding, the oscillation control mechanism 100 provided in this application uses a circulating fan as the application scenario. The working component 160 in this embodiment is the fan head assembly of the circulating fan, which includes fan blades and a drive motor to perform corresponding air supply operations. The oscillation control mechanism 100 can control the fan head assembly to operate in different modes during the air supply process, such as oscillating multi-directional air supply or fixed-directional air supply.

[0057] For example, the drive component 110 can be a rotary motor. During the operation of the circulating fan, the user can select whether the working component 160 needs to oscillate left and right as required. When left and right oscillation is required, the second transmission component 140 can be connected to the first transmission component 130. Under the action of the drive component 110, the first transmission component 130 rotates along its own axis, simultaneously driving the second transmission component 140 to rotate along its own axis, thereby causing the working component 160 connected to the second transmission component 140 to rotate. In this way, the left and right oscillation of the working component 160 is achieved by changing the rotation direction of the output shaft of the drive component 110. In an environment where oscillation is not required, the user can drive the second transmission component 140 to separate from the first transmission component 130. In this process, the drive component 110 drives the first transmission component 130 to idle, while the second transmission component 140 remains stationary, and the working component 160 only supplies air in a fixed direction. In summary, the oscillation control mechanism 100 can control oscillation according to user needs, avoiding excessive wear caused by prolonged contact of transmission components, extending the service life of the entire machine, and improving the user experience.

[0058] Continue reading Figure 2 As shown, in some embodiments, the first transmission member 130 includes a first bevel tooth portion 131 and a first straight tooth portion 132. The first bevel tooth portion 131 is in transmission engagement with the second transmission member 140, and the first straight tooth portion 132 is fixed to the side of the first bevel tooth portion 131 facing away from the second transmission member 140 and is in transmission engagement with the drive member 110.

[0059] See also Figure 3 As shown, specifically, the oscillation control mechanism 100 also includes an output gear 120. The axis of the output gear 120 is fixedly connected to the output shaft of the drive member 110, so as to rotate under the drive of the drive member 110. The first straight tooth portion 132 and the first bevel tooth portion 131 are coaxially arranged and connected through the same shaft. The first straight tooth portion 132 is meshed with the output gear 120, so that it can rotate along with the output gear 120 during rotation, thereby driving the first bevel tooth portion 131 to rotate. In addition, the speed of the first transmission member 130 can be adjusted by the tooth ratio of the output gear 120 and the first straight tooth portion 132, so that the working piece 160 can achieve the optimal oscillation rate. The first bevel gear can be connected to the second transmission member 140, thereby driving the second transmission member 140 and the working piece 160 to rotate and realize the change of transmission direction. The overall structure is simplified, reducing the number of components and the overall size of the machine.

[0060] Continue reading Figure 4As shown, the second transmission member 140 further includes a second spur tooth portion 141, a second bevel tooth portion 142, a third spur tooth portion 143, and a connecting shaft 144. The connecting shaft 144 passes through the second spur tooth portion 141, the second bevel tooth portion 142, and the third spur tooth portion 143 in sequence and is fixedly connected to all three. The second bevel tooth portion 142 is fixedly connected to the connecting shaft 144, and the second spur tooth portion 141 and the third spur tooth portion 143 are located on opposite sides of the second bevel tooth portion 142 and are slidably engaged with the connecting shaft 144. The working member 160 is transmissionally connected to the second spur tooth portion 141 and the third spur tooth portion 143 respectively, and the second bevel tooth portion 142 can be controllably engaged with the first bevel tooth portion 131.

[0061] For example, the second spur tooth 141, the second bevel tooth 142, and the third spur tooth 143 are coaxially arranged, the connecting shaft 144 is horizontally arranged, and the first transmission member 130 is vertically arranged. Thus, through the meshing of the second bevel tooth 142 with the first bevel tooth 131, vertical and horizontal transmission changes are achieved. Driven by the connecting shaft 144, the second bevel tooth 142 can move horizontally, thereby achieving meshing or disengagement between the second bevel tooth 142 and the first bevel tooth 131. Thus, when the second bevel tooth 142 meshes with the first bevel tooth 131, the second bevel tooth 142 rotates under the drive of the first bevel tooth 131, thereby driving the second spur tooth 141 and the third spur tooth 143, which are fixed to the connecting shaft 144, to rotate. This, in turn, drives the workpiece 160 connected to the second spur tooth 141 and the third spur tooth 143 to rotate, achieving the swaying control of the workpiece 160.

[0062] Furthermore, the second transmission component 140 also includes a handle portion 145, which is rotatably disposed at one end of the connecting shaft 144.

[0063] Specifically, the handle portion 145 is a vertical shaft with a hole in its middle for connecting to the connecting shaft 144. One end of the connecting shaft 144 is rotatably disposed within the hole in the handle portion 145 and cannot be disengaged from the handle portion 145 by means of a retaining spring or other components. Therefore, it can move along the axial direction under the traction of the handle portion 145, thereby driving the second bevel gear portion 142 to move closer to or away from the first bevel gear portion 131. Thus, the handle portion 145 facilitates the provision of lateral pulling force to the second transmission component 140, making the operation and adjustment of the second transmission component 140 convenient.

[0064] Continue reading Figure 5 As shown, further, the working part 160 includes a cover plate 161 and two racks 162 mounted on the cover plate 161. A receiving groove 1611 is provided in the middle of the cover plate 161. The second bevel tooth portion 142 is located at least partially in the receiving groove 1611. The two racks 162 are arranged opposite to each other on both sides of the receiving groove 1611 and mesh with the second straight tooth portion 141 and the third straight tooth portion 143 respectively.

[0065] Understandably, the working component 160 serves as the head assembly of the circulating fan, comprising a fan body and a cover plate 161 mounted below the fan body, thereby driving the entire fan body to rotate via the cover plate 161. The width of the receiving groove 1611 is greater than the thickness of the portion of the second bevel tooth 142 located within the receiving groove 1611, allowing the second bevel tooth 142 to move along its own axis within the receiving groove 1611, thus enabling the second bevel tooth 142 to engage or disengage with the first bevel tooth 131. Both the cover plate 161 and the rack 162 are arc-shaped structures, so when the two racks 162 engage with the second straight tooth 141 and the third straight tooth 143 respectively, the second straight tooth 141 and the third straight tooth 143 rotate, driving the gear and the cover plate 161 to rotate, achieving overall oscillation of the fan body.

[0066] Continue reading Figure 6 and Figure 7 As shown, in some embodiments, the head-shaking control mechanism 100 further includes a bracket 180 and a base 170. The drive member 110 and the first transmission member 130 are mounted on the base 170, and the bracket 180 is mounted on the base 170 and covers the drive member 110 and the first transmission member 130. The bracket 180 has a through groove 181, a support groove 182 and an extension hole 183 on the side away from the base 170. The second bevel tooth portion 142 at least partially passes through the through groove 181. A portion of the connecting shaft 144 is located in the support groove 182. One end of the handle portion 145 is located in the extension hole 183, and the other end extends outward from the extension hole 183.

[0067] Specifically, the base 170 has multiple first mounting holes 171 and second mounting holes 172. The drive member 110 is locked to each of the first mounting holes 171 by bolts, thereby mounting the drive member 110 onto the base 170. The first transmission member 130 is connected to the second mounting hole 172 via a shaft, thereby mounting the first transmission member 130 onto the base 170 and maintaining the meshing of the output gear 120 with the first straight tooth portion 132.

[0068] A bracket 180 covers the base 170 and encloses the drive component 110 and the first transmission component 130 inside it to protect the components. The second bevel tooth 142, the second straight tooth 141, and the third straight tooth 143 are all located within the through groove 181. The second bevel tooth 142 has a partial horizontal overlap with the first bevel tooth 131, allowing it to mesh with the first bevel tooth 131 during horizontal movement. A support groove 182 can be provided on both sides of the through groove 181, allowing both ends of the connecting shaft 144 to be placed within a support groove 182, thus ensuring the second transmission component 140 is stably mounted on the bracket 180. A handle 145 is vertically mounted within the extension hole 183, with one end extending outwards from the extension hole 183, enabling the connecting shaft 144 to drive the second bevel tooth 142 to rotate relative to the handle 145.

[0069] Continue reading Figure 8 As shown, in some embodiments, the head-shaking control mechanism 100 further includes a control element 150, which includes a fork 151 and a handle 152. The fork 151 is fixedly connected to the handle portion 145, and the handle 152 is connected to the fork 151 to drive the handle portion 145 to move along the axial direction of the connecting shaft 144.

[0070] Specifically, the handle 152 is exposed on the outside of the bracket 180, making it easy for the user to operate. During the operation of the circulating fan, the user can operate the handle 152 to move the shift fork 151 and the connecting shaft 144, thereby adjusting the second bevel gear 142, which is convenient and labor-saving.

[0071] Continue reading Figure 9 and Figure 10 As shown, the shift fork 151 further includes a connecting portion and two connecting caps disposed opposite each other on the same side of the connecting portion, the connecting caps being connected to both ends of the handle portion 145 respectively. The control member 150 also includes a pin 153, which is rotatably mounted on the bracket 180, and its two ends are connected to the connecting portion and the handle 152 respectively.

[0072] Specifically, the two connecting caps and the connecting part form a Y-shaped structure, thereby allowing adjustment of the direction of force, facilitating the overall spatial positioning, and reducing the overall size of the machine. Both the connecting part and the handle 152 have square through holes, and the two ends of the pin 153 are correspondingly provided with square shaft ends, thus connecting to the connecting part and the handle 152. During rotation, the pin 153 rotates synchronously with the connecting part and the handle 152, preventing the pin 153 from rotating independently along its own axis. During operation, the user can drive the handle 152 and the pin 153 to rotate along the axis of the pin 153 by moving the end of the handle 152 away from the pin 153, thereby pulling the shift fork 151 and the connecting shaft 144 to move, achieving engagement between the second bevel tooth 142 and the first bevel tooth 131. Similarly, moving the handle 152 in the opposite direction will disengage the second bevel tooth 142 and the first bevel tooth 131.

[0073] Preferably, to facilitate the installation of the pin 153, the bracket 180 is provided with a third mounting hole 184. The pin 153 is rotatably disposed in the third mounting hole 184 to realize the assembly of the pin 153 and the bracket 180.

[0074] Continue reading Figure 11 As shown, further, the end of the handle 152 away from the pin 153 has a waist-shaped groove, which has an arc-shaped structure. The control component 150 also includes a locking bolt 154, one end of which passes through the waist-shaped groove and is connected to the bracket 180.

[0075] Specifically, the locking bolt 154 engages with the bracket 180 via a thread, thereby limiting the vertical offset of the handle 152 and ensuring the stable installation of the handle 152. Through the engagement of the slotted groove with the locking bolt 154, the handle 152 can rotate along the axis of the pin 153, and the movement trajectory of the handle 152 is limited, precisely setting the travel of the second tapered portion and ensuring the meshing accuracy between the second tapered portion and the first tapered portion.

[0076] Embodiments of this application also provide a circulating fan, including the oscillation control mechanism 100 of any of the above embodiments.

[0077] This embodiment has the head-shaking control mechanism 100 of any of the above embodiments, and therefore has all the beneficial effects of the head-shaking control mechanism 100 of any of the above embodiments, which will not be described in detail here.

[0078] In summary, the oscillation control mechanism 100 and circulating fan provided in this application can realize the left and right oscillation function of the circulating fan, and the noise generated during the transmission process is relatively small, resulting in quieter operation and improved user experience. The oscillation control mechanism 100 has a compact design, stable operation, and reduces shaking and jamming during oscillation. The wear of the running gears is relatively small, resulting in a longer service life and ensuring uniform oscillation range and stable speed. Maintenance costs are low, requiring less frequent maintenance and lubrication by the user, and power consumption is low during transmission, contributing to improved overall energy efficiency. This reduces the manufacturing cost of the circulating fan oscillation mechanism and enhances market competitiveness.

[0079] 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.

[0080] 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.
