Description

Technical Field

[0001] This utility model belongs to the field of handheld fan technology, and in particular relates to a handheld fan with attachment and installation function. Background Technology

[0002] To facilitate operation in rainy weather, some existing handheld fans typically feature an openable flip cover. This flip cover is connected to the handle via a snap-fit ​​mechanism, allowing the fan to be clamped and fixed to the umbrella handle.

[0003] However, this type of structure relies on a single buckle for locking. After prolonged or high-frequency use, the buckle is prone to wear, fatigue, or deformation, which can reduce the locking force and cause the flip cover to come loose unexpectedly, resulting in problems such as the fan falling off. This not only affects the reliability of use but also poses certain safety hazards. Summary of the Invention

[0004] To address the shortcomings of existing technologies, a handheld fan with attachment and installation functionality is provided.

[0005] This utility model is achieved using the following technical solution:

[0006] A handheld fan with attachment and mounting function includes a handle for a user to hold and a head for blowing air. The head is hinged to one axial end of the handle. A first fastening member is hinged to the circumferential side of the handle. The first fastening member extends along the axial direction of the handle and can rotate and open in a first horizontal direction. The first fastening member and the handle together enclose a receiving space for accommodating an umbrella handle. A second fastening member is provided at the other axial end of the handle. The second fastening member has a latch that can open and close in a second horizontal direction.

[0007] When a user needs to attach the handheld fan to the umbrella handle, the first fastener is opened, allowing the umbrella handle to be inserted into the receiving space along the second horizontal direction of the unlocked latch. After installation, the second fastener returns to its initial position and locks in place. The first fastener is then re-fastened and pressed tightly against the surface of the umbrella handle, thus achieving a double-locking fixation for the handheld fan. The opposing opening and closing methods of the first and second fasteners ensure the self-locking effect of the handheld fan, preventing it from falling off.

[0008] The first fastening component can be fastened and locked by any existing fastening method that can unlockably fix it to the handle, such as snap-fit ​​or magnetic fastening.

[0009] The handheld fan can be kept at a fixed height by the friction force after the first fastener is tightly attached to the surface of the umbrella handle.

[0010] Preferably, when the umbrella handle is placed in the receiving space, the opening action of the first fastener is to rotate away from the umbrella handle, and the locking action of the second fastener is to rotate towards the umbrella handle. Thus, the handheld fan is self-locked by the first fastener and the second fastener having opposite opening and closing directions, preventing the handheld fan from falling off.

[0011] Preferably, a honeycomb silicone is embedded in one end of the first fastening member near the handle. The honeycomb silicone includes a solid embedded part and a honeycomb part located near the handle. The honeycomb part is provided with a plurality of hollow units, and the inner cavity of the hollow unit extends in a direction parallel to the handle.

[0012] The hollow unit of the honeycomb section extends axially along the handle and undergoes directional deformation when subjected to compressive force in the radial direction. It can both fill assembly tolerances through elastic deformation shrinkage and maintain axial compressive strength by utilizing the supporting force of the hollow unit.

[0013] Preferably, the hollow unit is provided in two groups, and each group has four hollow units arranged symmetrically in a parallelogram. The hollow unit makes the honeycomb part have an flared structure that expands in the direction close to the stalk. The two outermost hollow units have a cross-sectional notch that can reduce their own structural strength.

[0014] The honeycomb section with its flared structure can naturally expand radially when compressed to fill the irregular gap between the handle and the first fastener. The parallelogram arrangement gives the honeycomb section the ability to deform in a directional manner, and the compressive stress is dispersed along a preset path through orderly collapse, thus avoiding local stress concentration.

[0015] Preferably, the second fastening member is a circular ring structure with a notch. The latch is an arc-shaped rod structure and is hinged in the notch. The latch and the second fastening member combine to form a complete ring structure. The complete ring structure has the same shape as the outer edge of the axial end face of the handle. The complete ring structure is hinged to the axial end face of the handle.

[0016] By hinged a complete ring structure to the handheld fan, it can form a double locking structure with the first fastener in the normal state. When the handheld fan is not in use, the complete ring structure can be flipped outward to suspend it on an existing support rod or shelf as a hook, making it convenient for hanging and placing the handheld fan.

[0017] Preferably, the axial end face of the handle extends into an ear portion, and the second fastener is hinged to both ends of the ear portion in the width direction, thereby facilitating the hinged installation of the second fastener.

[0018] Preferably, the axial end face of the handle extends to form a hinge base, the hinge base having the same thickness as the ear, and an inwardly recessed stepped surface is formed between the hinge base and the handle, the second fastener being accommodated within the stepped surface, and a clearance groove being provided at one end of the hinge base near the accommodating space.

[0019] Preferably, a locking position is provided at one end of the notch away from the rotating shaft of the latch, and a horizontal stop perpendicular to the axis of the handle is provided in the locking position. The horizontal stop and the locking position together form a locking position to prevent the latch from deflecting and failing. The end of the latch fits the shape of the locking position.

[0020] Preferably, the accommodating space is formed by a combination of a first slot and a second slot respectively opened on the handle and the first fastening member. The cross-section of the first slot and the second slot is semi-circular, which facilitates fitting with the umbrella handle.

[0021] Preferably, anti-slip pads are provided on the inner walls of the first and second slots.

[0022] By using anti-slip pads, the gap between the storage space and the umbrella handle can be reduced, thereby increasing the friction between the handheld fan and the umbrella handle.

[0023] The anti-slip pad can be any existing friction pad used to increase friction with the umbrella handle surface, such as a patch with a corrugated surface or a rubber pad made of rubber.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] The first and second fasteners, which are designed to lock and unlock in opposite directions, fix the handle to the umbrella handle, thus achieving double locking protection for the handheld fan. This eliminates the risk of the handheld fan falling off due to wear and loosening caused by traditional single buckles, allowing the handheld fan to be used without holding it while attached to the umbrella, making it convenient for users to use when opening the umbrella.

[0037] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0038] like Figure 1 — Figure 6 As shown, this embodiment discloses a handheld fan with attachment and installation function, including a handle 11 for the user to hold and a head 12 for blowing air. The head 12 is hinged to the upper axial end of the handle 11. The handle 11 has a battery 31 and a switch 17 with the same structure as in the prior art. The switch 17 is electrically connected to the battery 31 through existing wiring. An impeller (not shown in the figure) for blowing air is rotatably provided inside the head 12. The battery 31 provides power to the impeller through existing wiring to make it rotate and blow air.

[0039] The handle 11 is hinged to the circumferential side with a first fastening member, which is a long strip-shaped flap 13. The handle 11 is assembled from a front cover 111 and a rear cover 112. The side end faces of the front cover 111 and the rear cover 112 are fixed by screws through a side cover bracket 113, which further tightens the front cover 111 and the rear cover 112. The side cover bracket 113 is the end face of the corresponding flap 13.

[0040] The flap 13 extends along the axial direction of the handle 11 and can rotate to open and close in the first horizontal direction. A buckle 14 is provided on the wide side of the flap 13 away from the rotation axis. The handle 11 has a movable groove 15 corresponding to the buckle 14. The movable groove 15 is an L-shaped through cavity, so that the front cover 111 and the side cover bracket 113 have communicating openings. A button 16 for pressing to unlock the buckle 14 is slidably provided in the movable groove 15. The button 16 has the same structure as the prior art. When the button 16 located in the front cover 111 is pressed, the part of the button 16 located in the side cover bracket 113 moves in the same direction. When the flap 13 rotates towards the handle 11, the buckle 14 can be engaged in the movable groove 15, realizing the unlockable fixation between the flap 13 and the handle 11.

[0041] In the initial state, button 16 is in the outer limit position, and button 16 abuts against buckle 14 to lock it in the locked state.

[0042] The flap 13 has a first slot 18 along its length, and the side cover bracket 113 has a second slot 19 on its inner side. The cross-sections of the first slot 18 and the second slot 19 are both semi-circular. The first slot 18 and the second slot 19 together form a receiving space 20 for the umbrella handle (not shown in the figure).

[0043] To prevent the handheld fan from slipping along the length of the umbrella handle, an anti-slip pad 21 is provided on the inner wall of the first slot 18, and two cell units (not shown in the figure) are provided on the inner wall of the second slot 19 along the axial direction, in which honeycomb silicone 32 is embedded, thereby increasing the friction between the handheld fan and the umbrella handle.

[0044] The honeycomb silicone 32 includes a solid insert 321 and a honeycomb portion 322 located near the handle. The honeycomb silicone 32 is inserted into the cell of the second slot 19 through the insert 321. The honeycomb portion 322 is provided with a plurality of hollow units 3221. The inner cavity of the hollow unit 3221 extends in a direction parallel to the handle 11. There are two sets of hollow units 3221, and each set has four hollow units 3221 arranged symmetrically in a parallelogram. The hollow units 3221 make the honeycomb portion 322 have an flared structure that expands in a direction close to the handle 11. The two outermost hollow units 3221 have a cross-sectional notch 3222 that can reduce their own structural strength.

[0045] The axial end face of the handle 11 extends to the ear 28. The second fastener 23 is hinged to both ends of the ear 28 in the width direction. The axial end face of the handle 11 extends to the hinge base 29. The hinge base 29 has the same thickness as the ear 28. An inwardly recessed stepped surface is formed between the hinge base 29 and the handle 11. The second fastener 23 is accommodated in the stepped surface. The hinge base 29 has a relief groove 30 at one end near the accommodating space 20. The other axial end of the handle 11 is provided with the second fastener 23. The second fastener 23 has a latch 25 that can be opened and closed in the second horizontal direction.

[0046] The second fastening member 23 is a circular ring structure with a notch 24. The latch 25 is an arc-shaped rod structure and is hinged in the notch 24. The latch 25 and the second fastening member 23 are combined to form a complete ring structure 22. The complete ring structure 22 has the same shape as the outer edge of the axial end face of the handle 11. The complete ring structure 22 is hinged to the axial end face of the handle 11.

[0047] A locking position 26 is provided at one end of the notch 24 away from the rotation axis of the latch 25. A crossbar 27 perpendicular to the axis of the handle 11 is provided in the locking position 26. The crossbar 27 and the locking position 26 together form a locking position to prevent the latch 25 from deflecting and failing. The end of the latch 25 matches the shape of the locking position.

[0048] When the umbrella handle is placed in the receiving space 20, the opening action of the flap 13 is to rotate away from the umbrella handle, and the opening action of the latch 25 of the second fastener 23 is to rotate towards the umbrella handle.

[0049] When users need air circulation around them on hot, sunny days or in humid, rainy days, since it is inconvenient to hold both an umbrella and a fan at the same time, they can press button 16 to unlock the flap 13, flip the flap 13 outwards, and use the second slot 19 of the handle 11 to press against the outer surface of the umbrella handle. During this process, the umbrella handle moves towards the inner ring of the complete annular structure 22, thereby abutting against the latch 25, which in turn causes the latch 25 to swing inwards to make room for the umbrella handle. When the gap between the latch 25 and the side wall of the notch 24 is larger than the diameter of the umbrella handle, the umbrella handle enters the inner side of the complete annular structure 22. At this time, the flap 13 is re-fastened to make the first slot 18 press against the outer surface of the umbrella handle, allowing the handheld fan to be attached to the umbrella handle. The friction force keeps the handheld fan at a suitable height. The impeller is started by switching on switch 17 to make it rotate and produce air.
