In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0048] In the description of the present application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0049] In addition, if the term "and / or" appears, "and / or" is merely a description of the association relationship of associated objects, indicating that three relationships may exist, for example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the objects associated before and after are in an "or" relationship. If the terms "first" and "second" appear, these terms are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "multiple" appears, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0050] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0051] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0052] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, 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 implementation method.

[0053] In the related art, the left and right shaking mechanism of some circulation fans is generally arranged inside the fuselage, and is driven by direct drive or connecting rod gear. However, the direct drive motor of the direct drive method may generate a lot of noise during operation, affecting the user experience. And long-term operation may cause the motor to overheat, affecting its life and stability, and there are problems such as uneven shaking range or unstable speed. In the connecting rod gear drive method, the connecting rod and gear are prone to wear during long-term use, resulting in unstable shaking of the head and even jamming. At the same time, the connecting rod gear drive structure is relatively complex and requires regular maintenance and lubrication, which increases the user's maintenance cost and has problems such as bulky appearance. In addition, neither of the above two methods can effectively control the shaking of the circulation fan, cannot be applied to application scenarios that do not require left and right shaking, and it is difficult to meet the diverse needs of users.

[0054] See also Figure 1 As shown, in order to improve the above-mentioned problems, an embodiment of the present application provides a shaking head control mechanism 100 to adjust the shaking head control of the circulation fan according to user needs, meet the fixed operation requirements of the non-shaking circulation fan, and improve the user experience and overall service life.

[0055] Specifically, the head shaking control mechanism 100 includes a driving member 110, a first transmission member 130, a second transmission member 140 and an operating member 160. The first transmission member 130 is in transmission connection with the driving member 110, the second transmission member 140 can be controlled to be connected to or separated from the first transmission member 130, and the operating 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 the present application is applied to a circulation fan. The operating member 160 in the embodiment of the present application is the head assembly of the circulation fan, which includes a fan blade and a drive motor to perform corresponding air supply operations, and the oscillation control mechanism 100 can control the head assembly to operate in different modes of oscillating multiple directions of air supply or fixed direction of air supply during the air supply process.

[0057] Exemplarily, the driving member 110 may be a rotating motor. During the operation of the circulating fan, the user may select whether the working member 160 needs to be shaken left and right according to the needs. When the shaking operation is required, the second transmission member 140 may be driven to be connected with the first transmission member 130, so that under the action of the driving member 110, the first transmission member 130 rotates along its own axis, and at the same time drives the second transmission member 140 to rotate along its own axis, thereby rotating the working member 160 connected to the second transmission member 140. In this way, the shaking of the working member 160 left and right is realized by changing the rotation direction of the output shaft of the driving member 110. In an environment where the shaking operation is not required, the user may drive the second transmission member 140 to separate from the first transmission member 130, so that in this process, the driving member 110 drives the first transmission member 130 to idle, the second transmission member 140 remains stationary, and the working member 160 only supplies air in a fixed direction. In summary, the shaking control mechanism 100 can be shaken according to the needs of the user, avoiding excessive wear caused by long-term contact of the transmission member, improving the service life of the whole 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 gear portion 131 and a first straight gear portion 132. The first bevel gear portion 131 is in transmission cooperation with the second transmission member 140, and the first straight gear portion 132 is fixed to a side of the first bevel gear portion 131 facing away from the second transmission member 140, and is in transmission cooperation with the driving member 110.

[0059] See also Figure 3 As shown, specifically, the shaking control mechanism 100 also includes an output gear 120, the axis of which is fixedly connected to the output shaft of the driving member 110 so as to rotate under the drive of the driving member 110. The first straight tooth portion 132 is coaxially arranged with the first bevel tooth portion 131 and connected through the same shaft. The first straight tooth portion 132 is meshedly connected with the output gear 120, so that it can follow the rotation during the rotation of the output gear 120, thereby driving the first bevel tooth portion 131 to rotate. In addition, the speed of the first transmission member 130 can be controlled by the gear ratio between the output gear 120 and the first straight tooth portion 132, so that the working member 160 can reach the optimal shaking speed. The first bevel gear can be connected to the second transmission member 140, thereby driving the second transmission member 140 and the working member 160 to rotate, and realizing the change of the transmission direction. The overall structure is streamlined, the component settings are reduced, and the volume of the whole machine is reduced.

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

[0061] Exemplarily, the second spur gear portion 141, the second bevel gear portion 142 and the third spur gear portion 143 are coaxially arranged, the connecting shaft 144 is horizontally arranged, and the first transmission member 130 is vertically arranged, so that the transmission change between the vertical direction and the horizontal direction is realized through the meshing of the second bevel gear portion 142 and the first bevel gear portion 131. The second bevel gear portion 142 can move in the horizontal direction under the drive of the connecting shaft 144, so as to realize the meshing or separation of the second bevel gear portion 142 and the first bevel gear portion 131. In this way, when the second bevel gear portion 142 is meshed with the first bevel gear portion 131, the second bevel gear portion 142 rotates under the drive of the first bevel gear portion 131, thereby driving the second spur gear portion 141 and the third spur gear portion 143 fixed to the connecting shaft 144 to rotate, and then driving the working member 160 connected to the second spur gear portion 141 and the third spur gear portion 143 to rotate, so as to realize the shaking control of the working member 160.

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

[0063] Specifically, the handle portion 145 is a vertical shaft, and a hole for connecting with the connecting shaft 144 is opened in the middle thereof. One end of the connecting shaft 144 is rotatably disposed in the hole of the handle portion 145, and can be prevented from being separated from the handle portion 145 by components such as a retaining spring, so that it can move along the axial direction under the traction of the handle portion 145, thereby driving the second bevel gear portion 142 to approach or move away from the first bevel gear portion 131. In this way, through the arrangement of the handle portion 145, it is convenient to provide a lateral pulling force to the second transmission member 140, and facilitate the control and adjustment of the second transmission member 140.

[0064] Continue reading Figure 5 As shown, further, the working piece 160 includes a cover plate 161 and two racks 162 installed on the cover plate 161, a receiving groove 1611 is opened in the middle of the cover plate 161, the second bevel tooth portion 142 is at least partially located in the receiving groove 1611, and the two racks 162 are relatively arranged on both sides of the receiving groove 1611, and are respectively engaged with the second straight tooth portion 141 and the third straight tooth portion 143.

[0065] It can be understood that the operating member 160 serves as a head assembly of the circulating fan, which includes a fan body and a cover plate 161 installed under the fan body, so that the fan body is driven to rotate as a whole through the cover plate 161. The width of the receiving groove 1611 is greater than the thickness of the portion of the second bevel gear portion 142 located in the receiving groove 1611, so that the second bevel gear portion 142 can move along its own axis in the receiving groove 1611, thereby realizing the engagement or separation of the second bevel gear portion 142 with the first bevel gear portion 131. The cover plate 161 and the rack 162 are both arc-shaped structures, so that when the two racks 162 are respectively engaged with the second spur gear portion 141 and the third spur gear portion 143, the second spur gear portion 141 and the third spur gear portion 143 rotate, and drive the gear and the cover plate 161 to rotate, so as to realize the overall shaking 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 driving 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 driving member 110 and the first transmission member 130. A through slot 181, a supporting slot 182 and an extension hole 183 are provided on a side of the bracket 180 away from the base 170, the second bevel gear portion 142 is at least partially penetrated through the through slot 181, a portion of the connecting shaft 144 is located in the supporting slot 182, one end of the handle portion 145 is located in the extension hole 183, and the other end extends outward of the extension hole 183.

[0067] Specifically, the base 170 is provided with a plurality of first mounting holes 171 and second mounting holes 172, and the driving member 110 is locked with each of the first mounting holes 171 by bolts, so that the driving member 110 is mounted on the base 170. The first transmission member 130 is connected with the second mounting holes 172 by a shaft, so that the first transmission member 130 is mounted on the base 170, and the output gear 120 is kept meshed with the first spur gear portion 132.

[0068] The bracket 180 is covered on the base 170, and covers the driving member 110 and the first transmission member 130 inside thereof to protect the components. The second bevel gear portion 142, the second spur gear portion 141 and the third spur gear portion 143 are all located in the through slot 181, and the second bevel gear portion 142 partially overlaps with the first bevel gear portion 131 in the horizontal direction, so as to be able to mesh with the first bevel gear portion 131 during the horizontal movement. Both sides of the through slot 181 can be provided with a support slot 182, so that the two ends of the connecting shaft 144 can be placed in a support slot 182 respectively, so that the second transmission member 140 can be stably installed on the bracket 180. The handle portion 145 is vertically installed in the extension hole 183, and one end thereof extends outward from the extension hole 183, so that the connecting shaft 144 can drive the second bevel gear portion 142 to rotate relative to the handle portion 145.

[0069] Continue reading Figure 8 As shown, in some embodiments, the shaking control mechanism 100 also includes a control member 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 outside the bracket 180, so as to facilitate the user's operation. During the operation of the circulating fan, the user can operate the handle 152 to drive the fork 151 and the connecting shaft 144 to move, thereby adjusting the second bevel gear portion 142, which is convenient and labor-saving.

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

[0072] Specifically, the two connecting caps and the connecting part form a Y-shaped structure, thereby adjusting the direction of the force, facilitating the overall spatial position setting, and reducing the volume of the whole machine. The connecting part and the handle 152 are both provided with square through holes, and the two ends of the pin 153 are correspondingly provided with square shaft ends, so as to be connected with the connecting part and the handle 152, and rotate synchronously with the connecting part and the handle 152 during the rotation process, so as to prevent the pin 153 from rotating alone along its own axis. During the operation process, the user can drive the handle 152 and the pin 153 to rotate along the axis of the pin 153 by toggling one end of the handle 152 away from the pin 153, thereby pulling the fork 151 and the connecting shaft 144 to move, so as to achieve the meshing of the second bevel tooth portion 142 with the first bevel tooth portion 131. Similarly, the second bevel tooth portion 142 and the first bevel tooth portion 131 can be separated by toggling the handle 152 in the opposite direction.

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

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

[0075] Specifically, the locking bolt 154 is threadedly matched with the bracket 180, thereby limiting the vertical displacement of the handle 152 and ensuring the stable installation of the handle 152. Through the matching of the waist groove and the locking bolt 154, the handle 152 can rotate along the axis of the pin shaft 153, and the movement trajectory of the handle 152 is limited, the movement stroke of the second tapered portion is accurately set, and the meshing accuracy of the second tapered portion and the first tapered portion is ensured.

[0078] In summary, the shaking head control mechanism 100 and the circulating fan provided by the present application can realize the left and right shaking head function of the circulating fan, and the noise generated during the transmission process is relatively small, the operation is quieter, and the user experience is improved. The shaking head control mechanism 100 is compact in design and stable in operation, reducing shaking and jamming during the shaking head. The wear of the running gear is relatively small and the service life is longer, which can ensure a uniform shaking range and stable speed. The maintenance cost is low, and the user does not need to perform maintenance and lubrication frequently. The power consumption during the transmission process is low, which helps to improve the overall energy efficiency. It can reduce the manufacturing cost of the shaking head mechanism of the circulating fan and improve market competitiveness.

[0079] The technical features of the above-described embodiments may be arbitrarily combined.
