Description

Technical Field

[0001] This application relates to the field of fan technology, and more specifically, to a handheld fan based on structural optimization. Background Technology

[0002] A handheld fan, as the name suggests, is a fan that is easy to hold and carry. It is usually small in size and lightweight, and can be easily put into a backpack, handbag or pocket, making it convenient for users to use anytime and anywhere.

[0003] Handheld fans typically consist of a handheld part and a fan part that is fixedly connected to the handheld part. When in use, the user holds the handheld part, and the fan part blows air towards the user to achieve the purpose of cooling.

[0004] The drawback of the existing technology is that since the fan and the handheld part are fixedly connected, the blowing angle of the fan is fixed, which prevents the user from adjusting the blowing angle of the fan according to actual usage needs. Therefore, it is urgent to improve this technology. Utility Model Content

[0005] Therefore, it is necessary to provide a handheld fan based on structural optimization to address the above problems, which aims to make the air blowing angle of the fan adjustable so that users can adjust the air blowing angle of the fan according to their actual needs.

[0006] The embodiments of this application achieve the above objectives through the following technical solutions.

[0007] This application provides a handheld fan based on structural optimization, the handheld fan comprising: a handheld part, a fan part, a rotating shaft, and a damping component; wherein,

[0008] The handheld part is rotatably connected to the fan part through the pivot member, thereby clamping the damping member between the handheld part and the fan part;

[0009] The fan unit has a rotating state that rotates relative to the handheld part under the action of an external force, and a fixed state that is fixed relative to the handheld part under the action of the damping member after the external force is removed.

[0010] In one embodiment, the rotating shaft includes a rotating shaft body, a first limiting part and a second limiting part, wherein the first limiting part and the second limiting part are spaced apart along the axial direction of the rotating shaft body on the outer periphery of the rotating shaft body;

[0011] A portion of the rotating shaft body is inserted into the fan section, and another portion of the rotating shaft body is inserted into the handheld section. The portion of the fan section through which the rotating shaft body is inserted and the portion of the handheld section through which the rotating shaft body is inserted are rotatably abutted against each other and confined between the first limiting portion and the second limiting portion.

[0012] In one embodiment, the fan portion is fixed to the first limiting portion; or, the handheld portion is fixed to the second limiting portion.

[0013] In one embodiment, the first limiting portion is provided with a guide surface, which is inclined inward in the direction from the first limiting portion to the second limiting portion.

[0014] In one embodiment, the fan portion is provided with a first connecting portion, and the handheld portion is provided with a second connecting portion, the second connecting portion being sleeved outside the first connecting portion;

[0015] A first limiting surface is formed on the inner circumferential surface of the first connecting part, and a second limiting surface is formed on the inner circumferential surface of the second connecting part. The rotating shaft body passes through the first connecting part and the second connecting part. The side of the first limiting part near the second limiting part abuts against the first limiting surface, and the side of the second limiting part near the first limiting part abuts against the second limiting surface.

[0016] In one embodiment, the fan portion is provided with a first connecting portion, and the handheld portion is provided with a second connecting portion, the second connecting portion being sleeved outside the first connecting portion;

[0017] The outer peripheral surface of the first connecting part is formed with a third limiting surface, and the inner peripheral surface of the second connecting part is formed with a fourth limiting surface. The damping member is sandwiched between the third limiting surface and the fourth limiting surface.

[0018] In one embodiment, the third limiting surface and the fourth limiting surface are spaced apart along the axial direction of the rotating shaft.

[0019] In one embodiment, the structurally optimized handheld fan further includes a washer fitted onto the first connecting portion and sandwiched between the damping member and the third limiting surface.

[0020] In one embodiment, the damping element is annular and arranged around the pivot.

[0021] In one embodiment, the handheld part includes a handle and a connecting arm. One end of the connecting arm is connected to the handle, and the other end of the connecting arm is rotatably connected to the fan part through the pivot member, thereby clamping the damping member between the connecting arm and the fan part. The fan part has a rotational state in which it rotates relative to the connecting arm under the action of an external force, and a fixed state in which it is fixed relative to the connecting arm under the action of the damping member after the external force is removed.

Detailed Implementation

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0032] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0033] This application provides a handheld fan based on structural optimization. The handheld part is rotatably connected to the fan part via a pivot, and a damping component is provided between the handheld part and the fan part. This allows the fan part to rotate relative to the handheld part when subjected to external force, and to be fixed relative to the handheld part when the external force is removed. This enables the user to adjust the blowing angle of the fan part according to actual usage needs, thus optimizing the user experience.

[0034] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0035] Please see Figures 1 to 3This application provides a handheld fan 1000 based on structural optimization. The handheld fan 1000 based on structural optimization includes: a handheld part 100, a fan part 200, a rotating shaft 300, and a damping part 400.

[0036] The handheld part 100 is for the user to hold and is equipped with other components such as a battery and a circuit board. The fan part 200 is used to blow air to the user. Specifically, the fan part 200 has an air inlet, an air outlet, and a guide channel connecting the air inlet and the air outlet. A fan assembly is installed in the guide channel. The fan assembly is used to drive the airflow through the air inlet, the guide channel, and the air outlet in sequence and blow it to the user.

[0037] Both the handheld part 100 and the fan part 200 can have various shapes, including standard cylindrical, elliptical cylindrical, prismatic, cuboid, and other shapes. Furthermore, the outer shells of the handheld part 100 and the fan part 200 can be formed in various ways. They can be single, complete components formed by machining, molding, 3D printing, or other processing methods; they can also be assembled from multiple components, fixed together by fastening, bonding, ultrasonic welding, or other methods. No specific limitations are made here.

[0038] The handheld part 100 is rotatably connected to the fan part 200 via a pivot 300, and the damping member 400 is clamped between the handheld part 100 and the fan part 200. This allows for the synchronous assembly and disassembly of the pivot 300 and the damping member 400. The pivot connection can be either a clearance fit between the outer peripheral wall of the pivot 300 and the corresponding inner peripheral wall of the handheld part 100, or a clearance fit between the outer peripheral wall of the pivot 300 and the corresponding inner peripheral wall of the fan part 200. Specifically, in this embodiment, the pivot 300 is configured as a non-damped pivot structure. This configuration allows for flexible adjustment of the rotation angle of the fan part 200 relative to the handheld part 100 and also reduces the cost of the pivot 300.

[0039] Furthermore, the handheld part 100 is rotatably connected to the circumferential side of the fan part 200 via a pivot 300, thereby allowing the fan part 200 to rotate vertically and adjust the airflow direction of the fan part 200 vertically. Alternatively, the handheld part 100 can also be rotatably connected to the circumferential top or bottom of the fan part 200 via the pivot 300.

[0040] The fan unit 200 has a rotating state in which it rotates relative to the handheld part 100 under the action of an external force, and a fixed state in which it is fixed relative to the handheld part 100 under the action of the damping member 400 after the external force is removed. Obviously, when the fan unit 200 is in the rotating state, the external force on the fan unit 200 overcomes the damping force of the damping member 400.

[0041] Specifically, the damping element 400 is at least partially elastic, allowing it to elastically abut against the fan section 200. The elastic friction between the damping element 400 and the fan section 200 is the damping force between them. The damping element 400 can be made of various materials, including rubber, silicone, silicone rubber, plastic, and other elastic materials; no specific limitation is made here.

[0042] As an example, and not a limitation, the damping force is positively correlated with the contact strength between the damping element 400 and the fan section 200; the greater the contact strength between the damping element 400 and the fan section 200, the greater the damping force. Similarly, the number of damping elements 400 can be set to one or more, and the damping force is also positively correlated with the number of damping elements 400; the more damping elements 400 there are, the greater the damping force. Therefore, in practical applications, the magnitude of the damping force can be adjusted by adjusting the contact strength between the damping element 400 and the fan section 200, as well as the number of damping elements 400.

[0043] There are many types of damping elements 400. In this embodiment, the damping element 400 is annular and surrounds the rotating shaft 300. Obviously, this annular shape can be closed or open, thus making the damping element 400 a circular damping structure, which enhances the damping force between the damping element 400 and the fan section 200. In other embodiments, the damping element 400 can also be a sheet-like damping structure or a block-like damping structure. Furthermore, since there are many types of damping elements 400, when multiple damping elements 400 are used, the types of each damping element 400 can be the same or different.

[0044] Furthermore, the axis of the damping element 400 coincides with the axis of the rotating shaft 300, which enhances the stability of the damped rotation formed by the rotating shaft 300 and the damping element 400. Alternatively, the axis of the damping element 400 and the axis of the rotating shaft 300 can be arranged parallel to each other at intervals.

[0045] Through the above technical solution, when it is necessary to adjust the blowing angle of the fan 200, an external force is first applied to the fan 200 to overcome the damping force between the fan 200 and the damping member 400, so that the fan 200 is in a rotating state relative to the handheld part 100 until the blowing angle of the fan 200 is adjusted to the preset angle. Then the external force applied to the fan 200 is removed, so that the fan 200 is in a fixed state relative to the handheld part 100 under the action of the damping member 400. This allows the user to adjust the blowing angle of the fan 200 according to actual usage needs, thus optimizing the user experience.

[0046] There are many types of the aforementioned pivot component 300; please refer to [link / reference needed]. Figures 4 to 6 In one embodiment of this application, the rotating shaft 300 includes a rotating shaft body 310, a first limiting part 320, and a second limiting part 330. The first limiting part 320 and the second limiting part 330 are spaced apart along the axial direction of the rotating shaft body 310 on the outer periphery of the rotating shaft body 310. A portion of the rotating shaft body 310 passes through the fan part 200, and another portion of the rotating shaft body 310 passes through the handheld part 100. The portion of the fan part 200 through which the rotating shaft body 310 passes and the portion of the handheld part 100 through which the rotating shaft body 310 passes are rotatably abutted and limited between the first limiting part 320 and the second limiting part 330. This arrangement simplifies the structure of the rotating shaft 300, making it convenient to achieve a rotatable connection between the fan part 200 and the handheld part 100 through the rotating shaft 300, and also ensures the stability of the fan part 200 when rotating relative to the handheld part 100.

[0047] The pivot 300 is elastic, and its material can be set with reference to the material of the damping component 400 in the above embodiment. It will not be described in detail here. This allows the pivot 300 to deform under external force, so that the pivot 300 can be inserted into the handheld part 100 and the fan part 200.

[0048] There are many types of first limiting part 320 and second limiting part 330. They can all be multiple limiting protrusions 321 arranged circumferentially along the rotating shaft body 310, or they can all be limiting rings 331 extending circumferentially along the rotating shaft body 310. No specific limitation is made here. Figure 6 The diagram shows a case where the first limiting part 320 consists of multiple limiting protrusions 321, and the second limiting part 330 consists of a limiting ring 331.

[0049] Further, please refer to Figure 6 The outer peripheral wall of the rotating shaft body 310 is provided with multiple reinforcing ribs 311 arranged at intervals along its circumference. Each reinforcing rib 311 also extends along the axial direction of the rotating shaft body 310. Each reinforcing rib 311 connects to the corresponding position of the limiting protrusion 321 and the limiting ring 331, thereby enhancing the structural strength of the rotating shaft component 300.

[0050] Furthermore, please refer to Figures 4 to 6 The rotating shaft body 310 is a cylindrical shape with open ends. This design allows wires to pass through the rotating shaft body 310 to electrically connect the electrical connection parts in the fan section 200 and the handheld section 100. Furthermore, it facilitates deformation of the rotating shaft body 310 under external force, making it easier to insert the rotating shaft body 310 into the handheld section 100 and the fan section 200. Obviously, in other embodiments, the rotating shaft body 310 can also be a solid shaft.

[0051] In this embodiment, the rotating shaft body 310, the first limiting part 320, and the second limiting part 330 are integrally formed, which facilitates the forming of the rotating shaft part 300 and enhances its structural strength. Of course, in other embodiments, the connection between the rotating shaft body 310 and the first limiting part 320, and between the rotating shaft body 310 and the second limiting part 330, can be either fixed or detachable. Fixed connections can be achieved through bonding, ultrasonic welding, or other methods, while detachable connections can be achieved through threaded connections, snap-fit ​​connections, tenon and mortise connections, magnetic connections, or other methods.

[0052] Considering that fixing the hinge 300 to the handheld part 100 would enhance the stability of the fan unit 200 during rotation and effectively prevent noise caused by shaking of the hinge 300, thus improving the user experience, please refer to [link to relevant documentation]. Figures 4 to 6 In one embodiment of this application, the hand-held part 100 is fixed to the second limiting part 330, so that the rotating shaft 300 and the hand-held part 100 can be fixed.

[0053] Specifically, the second limiting part 330 is provided with a mounting hole 3301. By threading a screw through the mounting hole 3301 and screwing it into the handle part 100, the second limiting part 330 can be fixed into the handle part 100, thereby fixing the handle part 100 and the second limiting part 330 together. Furthermore, the connection method between the handle part 100 and the second limiting part 330 can also be configured as a fixed connection or a detachable connection as described in the above embodiments.

[0054] In some other embodiments of this application, the fan portion 200 is fixed to the first limiting portion 320, thus achieving the same effect as fixing the handheld portion 100 to the second limiting portion 330 in the above embodiment.

[0055] Preferably, the fan portion 200 is snapped into and fixed to the first limiting portion 320. Specifically, the outer periphery of the first limiting portion 320 is provided with a snap-fit ​​recess (not shown), and the fan portion 200 is provided with a snap-fit ​​protrusion (not shown) that mates with the snap-fit ​​recess. This ensures that the rotating shaft 300 and the fan portion 200 are fixed together and do not rotate relative to each other. Furthermore, the connection method between the fan portion 200 and the first limiting portion 320 can also be configured as a fixed connection or a detachable connection as described in the above embodiments.

[0056] For easy mounting of the hinge 300 onto the handheld part 100 and the fan part 200, please refer to Figures 4 to 6 In one embodiment of this application, the first limiting part 320 is provided with a guide surface 3201, which is inclined inward in the direction from the first limiting part 320 to the second limiting part 330.

[0057] There are many types of guide surface 3201. Guide surface 3201 can be a plane with an inclination, or a curved surface with an inclination. Guide surface 3201 can also be a plane with one part inclination and a curved surface with an inclination. No specific limitation is made here.

[0058] With the above technical solution, when the guide surface 3201 is pressed, the pressure on the first limiting part 320 is inclined relative to the axis of the rotating shaft body 310, which is beneficial for the first limiting part 320 to transmit the pressure to the rotating shaft body 310 when it is pressed, so that the rotating shaft body 310 can undergo elastic deformation when it is inserted, thereby facilitating the insertion of the rotating shaft 300 onto the handheld part 100 and the fan part 200. Specifically, when the pivot 300 is inserted into the handheld part 100 and the fan part 200, the guide surface 3201 presses against the inner wall of the portion of the handheld part 100 and the fan part 200 through which the pivot body 310 is inserted, so that the pressure on the first limiting part 320 is transmitted to the pivot body 310, causing the pivot body 310 to undergo elastic deformation until the first limiting part 320 abuts against the corresponding position in the fan part 200 and the second limiting part 330 abuts against the corresponding position in the handheld part 100. The pivot body 310 returns to its undeformed state under its own rebound force, thus completing the installation of the pivot 300.

[0059] There are many ways in which the aforementioned hinge 300 is inserted into the handheld part 100 and the fan part 200; please refer to [link / reference needed]. Figure 1 , Figure 2 as well as Figure 5 In one embodiment of this application, the fan part 200 is provided with a first connecting part 201, and the handheld part 100 is provided with a second connecting part 101. The second connecting part 101 is sleeved outside the first connecting part 201. A first limiting surface 2011 is formed on the inner peripheral surface of the first connecting part 201, and a second limiting surface 1011 is formed on the inner peripheral surface of the second connecting part 101. The rotating shaft body 310 passes through the first connecting part 201 and the second connecting part 101. The side of the first limiting part 320 near the second limiting part 330 abuts against the first limiting surface 2011, and the side of the second limiting part 330 near the first limiting part 320 abuts against the second limiting surface 1011. This arrangement makes it convenient for the rotating shaft 300 to pass through the handheld part 100 and the fan part 200.

[0060] Preferably, please refer to Figure 1 , Figure 2 as well as Figure 5The first limiting surface 2011 and the second limiting surface 1011 are both planar and perpendicular to the axis of the rotating shaft body 310, which facilitates the processing and forming of the first limiting surface 2011 and the second limiting surface 1011. In addition, the first limiting surface 2011 and the second limiting surface 1011 can also be inclined relative to the axis of the rotating shaft body 310.

[0061] It is worth mentioning that you should refer to Figure 1 , Figure 2 as well as Figure 5 The second connecting part 101 communicates with the interior of the hand-held part 100, and the hand-held part 100 can be split into two parts, so that the communication between the second connecting part 101 and the hand-held part 100 is exposed, thereby ensuring that the rotating shaft 300 can be sequentially inserted into the second connecting part 101 and the first connecting part 201.

[0062] There are many types of first connecting part 201 and second connecting part 101. In this embodiment, please refer to... Figure 1 , Figure 2 as well as Figure 5 The first connecting portion 201 is configured as a stepped hollow protrusion, meaning that both the outer and inner peripheral walls of the hollow protrusion are stepped. The second connecting portion 101 is configured as a stepped through hole. This configuration facilitates the fitting of the second connecting portion 101 onto the first connecting portion 201 and also facilitates the formation of the first limiting surface 2011, the second limiting surface 1011, and the third limiting surface 2012 and the fourth limiting surface 1012, which will be described below. Of course, in other embodiments, the first connecting portion 201 can also be configured as a stepped hollow protrusion, and the second connecting portion 101 can be configured as a collar, with the collar fitted around the outer periphery of the hollow protrusion.

[0063] In other embodiments, the handheld part 100 may have a first through hole communicating with its interior, and the fan part 200 may have a second through hole communicating with its interior. The rotating shaft body 310 may be sequentially inserted into the first through hole and the second through hole. The side of the first limiting part 320 near the second limiting part 330 abuts against the inner wall of the fan part 200 adjacent to the second through hole, and the side of the second limiting part 330 near the first limiting part 320 abuts against the inner wall of the handheld part 100 adjacent to the first through hole. In this way, the rotating shaft 300 can also be inserted into the handheld part 100 and the fan part 200.

[0064] There are many ways in which the aforementioned damping element 400 is disposed between the handheld part 100 and the fan part 200; please refer to [link / reference needed]. Figure 1 , Figure 2 as well as Figure 5In one embodiment of this application, a third limiting surface 2012 is formed on the outer peripheral surface of the first connecting part 201, and a fourth limiting surface 1012 is formed on the inner peripheral surface of the second connecting part 101. The damping member 400 is sandwiched between the third limiting surface 2012 and the fourth limiting surface 1012. This arrangement makes it convenient to disassemble and assemble the damping member 400, thereby facilitating the maintenance or replacement of the damping member 400.

[0065] Further, please refer to Figure 1 , Figure 2 as well as Figure 5 The fourth limiting surface 1012 is provided with a positioning groove 1013. A part of the damping member 400 cooperates with the positioning groove 1013, and the other part of the damping member 400 extends out of the positioning groove 1013 and elastically abuts against the third limiting surface 2012, thereby enhancing the stability of the damping member 400. Obviously, when the damping member 400 is annular and surrounds the rotating shaft 300, the positioning groove 1013 is also annular and surrounds the rotating shaft 300 accordingly.

[0066] In other embodiments, one end of the damping member 400 may be fixed to the fan part 200 by the fixed connection or detachable connection mentioned above, and the other end of the damping member 400 may elastically abut against the fan part 200, thus also realizing that the damping member 400 is located between the handheld part 100 and the fan part 200.

[0067] There are many types of the aforementioned third limiting surface 2012 and fourth limiting surface 1012; please refer to [the relevant documentation]. Figure 1 , Figure 2 as well as Figure 5 In one embodiment of this application, the third limiting surface 2012 and the fourth limiting surface 1012 are spaced apart along the axial direction of the rotating shaft 300, so that both the third limiting surface 2012 and the fourth limiting surface 1012 are planar. With this arrangement, when assembling or disassembling the first connecting part 201 and the second connecting part 101, the damping member 400 can be clamped or the clamping of the damping member 400 can be released through the third limiting surface 2012 and the fourth limiting surface 1012, thereby further facilitating the assembly and disassembly of the damping member 400.

[0068] In other embodiments, the third limiting surface 2012 may be set as the outer peripheral wall of the first connecting part 201, the fourth limiting surface 1012 may be set as the inner peripheral surface of the second connecting part 101, and the damping member 400 may be sandwiched between the outer peripheral wall and the inner peripheral wall.

[0069] To extend the service life of damper 400, please refer to [link / reference needed]. Figure 1 , Figure 2 as well as Figure 5In one embodiment of this application, the handheld fan 1000 based on structural optimization further includes a washer 500. The washer 500 is sleeved on the first connecting portion 201 and sandwiched between the damping member 400 and the third limiting surface 2012. This arrangement allows the damping member 400 and the washer 500 to elastically abut against each other, thereby reducing wear on the damping member 400 during long-term use and extending its service life. The material of the washer 500 is set with reference to the material of the damping member 400, which will not be described in detail here.

[0070] There are many types of the aforementioned handheld unit 100; please refer to [link / reference needed]. Figure 1 , Figure 2 as well as Figure 5 In one embodiment of this application, the handheld part 100 includes a handle 110 and a connecting arm 120. One end of the connecting arm 120 is connected to the handle 110, and the other end of the connecting arm 120 is rotatably connected to the fan part 200 through a pivot 300, thereby causing the damping member 400 to be clamped between the connecting arm 120 and the fan part 200. The fan part 200 has a rotating state in which it rotates relative to the connecting arm 120 under the action of an external force, and a fixed state in which it is fixed relative to the connecting arm 120 under the action of the damping member 400 after the external force is removed.

[0071] Specifically, please refer to Figure 1 and Figure 2 One end of the connecting arm 120 is connected to the upper corner of the handle 110, and the other end of the connecting arm 120 is rotatably connected to the circumferential side of the fan part 200 through the rotating shaft 300.

[0072] And, please see Figure 1 and Figure 2 The second connecting part 101 is disposed on the connecting arm 120 and communicates with the interior of the connecting arm 120. The connecting arm 120 includes a first part 121 and a second part 122. The first part 121 connects the handle 110 and the fan part 200. The second part 122 is detachably connected to the first part 121. When the second part 122 is removed from the first part 121, the communication between the second connecting part 101 and the connecting arm 120 is exposed, thereby ensuring that the rotating shaft 300 can be sequentially inserted into the second connecting part 101 and the first connecting part 201. The detachable connection between the second part 122 and the first part 121 is configured in accordance with the detachable connection method in the above embodiment, and will not be described in detail here.

[0073] In this embodiment, please refer to Figure 1 and Figure 2The handle 110 and the fan unit 200 are connected by a connecting arm 120. This configuration simplifies the structure of the handheld part 100 by allowing the handle 110 and the fan unit 200 to be connected using only one connecting arm 120. In other embodiments, the handle 110 and the fan unit 200 can also be connected by two connecting arms 120, with the first ends of the two connecting arms 120 located on the left and right sides of the upper part of the handle 110, and the second ends of the two connecting arms 120 located on the left and right sides of the fan unit 200.

[0074] In other embodiments, the handheld portion 100 may also be configured to include only the handle 110.
