Description

Technical Field

[0001] This utility model relates to the field of electric fan technology, specifically to a stable clamping structure for an umbrella handle fan. Background Technology

[0002] Many existing umbrella-handle fans use a simple clip-on structure, which has extremely limited adaptability to different umbrella handles. Because umbrella handles vary in material, shape, and thickness, ordinary clips struggle to fit all types. For example, with smooth metal handles, the clip cannot fit snugly and easily loosens and slips off when the fan vibrates. With thinner handles, the clip cannot provide sufficient clamping force, similarly failing to ensure fan stability. In windy weather, the increased external interference to the fan makes this simple clip structure even more ineffective at maintaining its position, severely impacting the user experience.

[0003] Therefore, there is a need for a structure that can stably clamp the fan to the umbrella handle. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a stable clamping structure for umbrella handle fans, which can stably clamp the umbrella handle.

[0005] The present invention provides a stable clamping structure for an umbrella handle fan, which is disposed on the fan body. The fan body has a receiving cavity for accommodating the umbrella handle, and the receiving cavity is lined with a first silicone sealant. A fan cover plate is hinged to the fan body, and a second silicone sealant is lined on the side of the fan cover plate facing the receiving cavity. The fan body also has a snap-fit ​​component inside, which is used to snap-fit ​​with the fan cover plate.

[0006] Compared with existing technologies, the stable clamping structure for an umbrella handle fan provided by this utility model lays a first silicone sealant in the receiving cavity that accommodates the umbrella handle, hinges a fan cover plate to the fan body, lays a second silicone sealant on the side of the fan cover plate facing the receiving cavity, and sets a snap-fit ​​component in the fan body to snap into the fan cover plate. Therefore, when the fan body is clamped to the umbrella handle, the first silicone sealant in the receiving cavity and the second silicone sealant on the fan cover plate simultaneously press the umbrella handle towards each other. This effectively increases the friction between the umbrella handle and the first silicone sealant, as well as between the umbrella handle and the second silicone sealant, thereby making the fan stably clamped to the umbrella handle. Therefore, this utility model utilizes the good flexibility and elasticity of the first and second silicone sealants to clamp the fan body to the umbrella handle, which can be used for umbrella handles of different materials and sizes, and prevents the fan from loosening and slipping due to its own vibration or external interference such as strong winds during operation. In addition, the first and second silicone rubbers can also serve as buffer components, effectively absorbing the vibrations generated by the fan operation and the vibrations caused by the shaking of the umbrella handle, reducing bidirectional vibration transmission, and preventing the connection parts from becoming loose due to vibration wear. This not only extends the service life of the fan and the umbrella handle, but also ensures that the fan always maintains a stable position during use, continuously providing an ideal blowing effect.

[0007] Specifically, the first silicone rubber is in sheet form, and the thicker end of the first silicone rubber extends outward from the inner wall of the receiving cavity. This arrangement allows for control of the thickness of the first silicone rubber while ensuring sufficient compression between the receiving cavity and the umbrella handle to provide adequate friction, thereby saving costs.

[0008] Specifically, the first silicone is in the form of a sheet, and the thick end of the first silicone extends outward from the inner wall of the receiving cavity.

[0009] Specifically, the first silicone rubber extends outward by a length L, and the depth of the receiving cavity is H, where 0.25H ≤ L ≤ 0.33H. This configuration provides sufficient friction to maintain clamping stability while preventing excessive compression of the first silicone rubber, thereby extending its service life.

[0010] Specifically, the thick end of the first silicone rubber extending outward has an arc-shaped end face. This design facilitates a closer fit between the first silicone rubber and the umbrella handle, enhancing the reliability of the clamping mechanism.

[0011] Specifically, there are multiple first silicone rubbers, and anti-slip ribs are provided between two adjacent first silicone rubbers. This arrangement can enhance the clamping force applied to the umbrella handle, reduce the relative movement between the fan and the umbrella handle, and thus improve the stability of the clamping.

[0012] Specifically, the snap-fit ​​assembly includes a snap-fit ​​ear, and the end face of the fan cover facing the receiving cavity is also provided with a snap hook. The snap hook can extend into the fan body and engage with the snap-fit ​​ear to fix the fan cover to the fan body.

[0013] Specifically, the snap-fit ​​assembly further includes a base and a push button. The base is slidably disposed within the fan body. The push button and the snap-fit ​​ear are both fixed to the base, and the push button protrudes from the fan body. The push button is used to push the base to slide to release the fan cover.

[0014] Specifically, the stabilizing clamping structure for the umbrella handle fan further includes a reset member disposed between the base and the fan body to reset the base.

[0015] Specifically, the fan body has a positioning groove at one end facing the fan cover, and the fan cover has a positioning flange at one end facing the fan body that cooperates with the positioning groove, so that the fan cover is positioned and covers the fan body.

Detailed Implementation

[0030] The present invention will now be further described in conjunction with the accompanying drawings and embodiments.

[0031] Please see Figures 1 to 3 as well as Figure 12The present invention provides a stable clamping structure 100 for an umbrella handle fan, which is mounted on a fan body 1. The fan body 1 has a receiving cavity 2 for accommodating an umbrella handle 200, and the receiving cavity 2 is lined with a first silicone rubber 21. A fan cover plate 3 is hinged to the fan body 1, and a second silicone rubber 31 is lined on the side of the fan cover plate 3 facing the receiving cavity 2. A snap-fit ​​assembly 4 is also provided inside the fan body 1 for snapping with the fan cover plate 3. Specifically, a rotating shaft 32 is provided on one side of the fan cover plate 3, and a support 11 that cooperates with the rotating shaft 32 is provided on the fan body 1. Both ends of the rotating shaft 32 extend into the support 11 to obtain support from the support 11. To improve the reliability of use, there are two rotating shafts 32, and two corresponding supports 11 are provided. A fan 300 is also provided on the fan body 1, and the fan 300 is rotatably connected to the fan body 1 to adjust the blowing angle.

[0032] Further, please refer to Figure 3 , Figure 5 , Figure 8 , Figure 11 and Figure 12 The first silicone 21 is sheet-shaped, and its thick end 211 extends outward from the inner wall of the receiving cavity 2, meaning the sheet-shaped first silicone 21 is fixedly inserted into the inner wall of the receiving cavity 2. This arrangement allows for control of the thickness of the first silicone 21 while ensuring sufficient compression between the receiving cavity 2 and the umbrella handle 200 to provide sufficient friction, thus saving costs. Furthermore, to ensure a tighter fit between the first silicone 21 and the umbrella handle 200, the outwardly extending thick end 211 of the first silicone 21 has an arc-shaped end face. The second silicone 31 is also sheet-shaped, and its thick end 311 extends in a direction parallel to the fan cover 3, meaning the second silicone 31 is attached to the end face of the fan cover 3 facing the receiving cavity 2. To facilitate the attachment of the second silicone 31, a limiting groove 30 is also provided on the end face of the fan cover 3 facing the receiving cavity 2 for easy positioning and attachment of the second silicone 31.

[0033] Further, please refer to Figure 6 The first silicone rubber 21 extends outward by a length L, and the depth of the receiving cavity 2 is H, where 0.25H ≤ L ≤ 0.33H. This configuration provides sufficient friction to maintain clamping stability while preventing excessive compression of the first silicone rubber 21, thereby extending its service life.

[0034] Further, please refer to Figure 3The first silicone rubber 21 is multiplied, and anti-slip ribs 22 are provided between two adjacent first silicone rubber 21 on the receiving cavity 2. This arrangement can enhance the clamping force applied to the umbrella handle 200, reduce the relative movement between the fan body 1 and the umbrella handle 200, and thus improve the clamping stability. In this embodiment, there are four pieces of the first silicone rubber 21, and three anti-slip ribs 22 are provided between two adjacent first silicone rubber 21.

[0035] Further, please refer to Figures 3 to 4 as well as Figures 7 to 9 The latching assembly 4 includes a latching ear 41, a base 42, and a push button 43. In this embodiment, to improve reliability, the latching ear 41, the base 42, and the push button 43 are integrally formed. A hook 33 is also provided on the end face of the fan cover 3 facing the receiving cavity 2. The hook 33 can extend into the fan body 1 and engage with the latching ear 41 to fix the fan cover 3 to the fan body 1. The base 42 is slidably disposed within the fan body 1. The push button 43 and the latching ear 41 are both fixed to the base 42, and the push button 43 protrudes outside the fan body 1. The push button 43 is used to push the base 42 to slide and release the fan cover 3. This design allows the hook 33 to enter the fan body 1 more smoothly and engage with the latching ear 41, while also reducing wear and increasing service life. The latching lug 41 is also provided with a guide slope 411, and the latching hook 33 includes a hook portion 331. The guide slope 411 is used to cooperate with the hook portion 33 to assist the hook portion 33 in engaging with the latching lug 41. This design can also reduce the wear of the latching hook 33 and extend its service life.

[0036] Further, please refer to Figure 4 and Figure 8 The stabilizing clamping structure 100 for the umbrella handle fan further includes a reset member 5, which is disposed between the base 42 and the fan body 1 to reset the base 42. In this embodiment, the reset member 5 is a hanging spring with hooks 51 at both ends. Correspondingly, the base 42 is provided with a first latch 421, and the fan body 1 is provided with a second latch 12. The hooks 51 at both ends of the reset member 5 are respectively fastened to the first latch 421 and the second latch 12.

[0037] Further, please refer to Figure 2 as well as Figures 11 to 12The fan body 1 has a positioning groove 13 at one end facing the fan cover 3, and the fan cover 3 also has a positioning flange 34 at one end facing the fan body 1, which cooperates with the positioning groove 13, so that the fan cover 3 is positioned and closed on the fan body 1. This arrangement ensures that when the umbrella handle fan is used as a handheld fan, the fan cover 3 fits perfectly and has a more aesthetically pleasing appearance.

[0038] The following is a description of the working principle of the stabilizing clamping structure 100 for an umbrella handle fan according to this utility model. When it is necessary to clamp the stabilizing clamping structure 100 for the umbrella handle fan onto the umbrella handle 200, first push the push button 43, the locking ear 41 and the locking hook 33 disengage from each other. Under the action of the elastic force provided by the second silicone 31, the fan cover 3 springs up from the fan body 1, and then the fan cover 3 is flipped over to expose the receiving cavity 2. Then the umbrella handle 200 can be placed into the receiving cavity 2. After the umbrella handle 200 is placed, the fan cover 3 is flipped again toward the direction closer to the receiving cavity 2, and the locking hook 33 is inserted into the fan body 1 again, so that the locking hook 33 engages with the locking ear 41 again, thereby stabilizing the umbrella handle 200 between the first silicone 21 and the second silicone. When it is necessary to separate the stabilizing clamping structure 100 for the umbrella handle fan from the umbrella handle 200, push the push button 43 to separate the hook 33 from the locking ear 41. Under the elastic force provided by the second silicone 31, the fan cover 3 springs off the fan body 1. Then, flip the fan cover 3 away from the receiving cavity 2, and the stabilizing clamping structure 100 for the umbrella handle fan can be separated from the umbrella handle 200. After separating the stabilizing clamping structure 100 for the umbrella handle fan from the umbrella handle 200, flip the fan cover 3 again towards the receiving cavity 2, and let the hook 33 extend into the fan body 1 again, so that the hook 33 hooks with the locking ear 41 again. At this time, the fan cover 3 also covers the surface of the fan body 1.

[0039] Compared with the prior art, the stable clamping structure 100 for umbrella handle fans provided by this utility model lays a first silicone 21 in the receiving cavity 2 that accommodates the umbrella handle 200, a fan cover plate 3 is hinged to the fan body 1, a second silicone 31 is laid on the side of the fan cover plate 3 facing the receiving cavity 2, and a snap-fit ​​component 4 is provided in the fan body 1 to snap with the fan cover plate 3. Therefore, when the fan body 1 is clamped to the umbrella handle 200, the first silicone 21 in the receiving cavity 2 and the second silicone 31 on the fan cover plate 3 simultaneously squeeze the umbrella handle 200 towards each other. This can effectively increase the friction between the umbrella handle 200 and the first silicone 21 and between the umbrella handle 200 and the second silicone 31, thereby making the fan 300 stably clamped to the umbrella handle 200. Therefore, this utility model utilizes the good flexibility and elasticity of the first silicone 221 and the second silicone 31 to clamp the fan 300 to the umbrella handle 200, which can be used with umbrella handles 200 of different materials and sizes, and prevents the fan 300 from loosening and slipping due to its own vibration or external interference such as strong winds during operation. In addition, the first silicone 21 and the second silicone 31 can also act as cushioning components, effectively absorbing the vibration generated by the operation of the fan 300 and the vibration caused by the shaking of the umbrella handle 200, reducing bidirectional vibration transmission, and preventing the connection parts from loosening due to vibration wear. This not only extends the service life of the fan 300 and the umbrella handle 200, but also ensures that the fan 300 maintains a stable position during use, continuously providing an ideal blowing effect.
