Description

Technical Field

[0001] The present invention relates to the technical field of household electrical appliances, and in particular to a portable handheld foldable rechargeable fan. Background Art

[0002] In daily travel, outdoor work, office and study scenarios, portable handheld fans have become a common tool for people to cope with the heat and improve their comfort experience due to their advantages of being small, light and able to deliver air at any time. High-speed fans, in particular, are in greater demand in high-temperature environments or scenarios where rapid cooling is required because they can provide strong wind power. With the popularization of lifestyles such as mobile office and outdoor exploration, users have increasingly stringent requirements for the portability and battery life flexibility of fans. They expect them to be available at any time and need to adapt to the power supply needs in various scenarios, which drives the iterative upgrade of product structure and function.

[0003] The current rechargeable high-speed handheld fan is mainly composed of a fan body (including core components such as fan blades, drive motor, speed control circuit, etc.), a built-in rechargeable battery, a charging interface and an integrated shell; its working principle is to store electrical energy through the built-in battery to power the motor to drive the fan blades to rotate at high speed to achieve wind output; when in use, the user adjusts the wind speed through the switch button, and connects the power cord with the help of the charging interface to replenish the power of the built-in battery; this type of fan relies on integrated design to achieve a compact and portable form, which can meet basic mobile air supply needs and is widely used in the market, providing convenience for users in close-range and short-term cooling scenarios.

[0004] Existing rechargeable high-speed handheld fans have obvious disadvantages in actual use: on the one hand, the built-in battery means that the battery life is limited to the capacity of a single battery pack. After the battery is exhausted, if the user needs to continue using it, he can only choose to use it while charging. This mode will cause the battery to be continuously in a charge and discharge cycle, accelerate battery aging, and significantly shorten the battery life; on the other hand, the fan cannot be freely carried away without the charging cable during charging, which limits the usage scenarios. For example, when you need to take a rechargeable high-speed handheld fan out, if the fan is in a state of low power, you cannot carry it with you, or you need to use a charging cable and a power bank to recharge the fan. At this time, the user needs to hold the power bank in one hand and the fan in the other hand. It is difficult to meet the user's needs for flexible electricity use anytime, anywhere, which is contrary to the core demand of portable fans. It is urgent to break through the dual limitations of battery life and portability through structural innovation.

[0005] A portable, handheld, foldable, rechargeable fan is needed for this purpose. Summary of the Invention

[0006] The present invention provides a portable handheld foldable rechargeable fan, which solves the problems in the prior art of short battery life and the inability to freely carry the fan without a charging cable.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A portable handheld foldable rechargeable fan comprises a control module, a high-speed fan module and a battery module. The control module and the battery module are detachably connected via a convenient detachable mechanism, and a connecting seat fixedly connected to the outer wall of the high-speed fan module is rotatably mounted on the top of the control module.

[0013] Preferably, the cross-section of the docking rod is designed in an "I" shape, which is used to ensure that the top outer wall and the bottom outer wall of the docking rod are in contact with the docking hole, and the corners of the outer wall of the docking rod are all designed at an angle, and the length of the docking rod is greater than the length of the USB plug.

[0014] Preferably, the lifting rack, driving gear and knob in the easy-to-detach mechanism are each provided with two groups, and the easy-to-detach mechanism also includes a transmission shaft fixedly connected to the two groups of lifting racks, driving gears and knobs, and the installation position of the lifting rack is staggered with the USB plug.

[0015] Preferably, the cross section of the lifting rack is designed to be in an inverted L-shape, and the distance between the top of the lifting rack and the axis of the driving gear is greater than the length of the docking rod.

[0016] Preferably, the hidden buckle ear mechanism includes a buckle ear groove provided on the outer wall of the control module and a lanyard buckle ear slidably installed in the buckle ear groove, and a notch for the lanyard to pass through is provided at the outer end of the bottom of the lanyard buckle ear, and the lanyard buckle ear is completely located in the buckle ear groove when not in use.

[0017] Preferably, the hidden buckle ear mechanism also includes an extension frame slidably installed in the control module and fixedly connected to the top of the lanyard buckle ear, and a limiting column fixedly installed in the control module and slidably connected to the extension frame, and a spring connected to the inner wall of the control module is installed on the outer wall of the top of the extension frame, and a T-shaped limiting rod slidably connected to the lanyard buckle ear is fixedly installed in the control module.

[0018] Preferably, the hidden buckle ear mechanism also includes a transmission wheel rotatably installed at the bottom of the lanyard buckle ear and a transmission frame slidably installed in the control module, and the outer wall of the transmission frame and the transmission wheel are in contact with a slope design, and the outer end of the transmission frame protrudes from the control module, and the outer wall of the connecting seat is fixedly installed with a pressure block for pushing the transmission frame, and after the connecting seat is rotated 90°, the outer wall will be in contact with the outer wall of the control module and push the transmission frame into the control module.

[0019] Preferably, an elastic locking block is installed at the position where the notch is opened on the lanyard buckle ear through a torsion spring and a rotating shaft, and the end face of the elastic locking block is in contact with the inner wall of the notch to ensure that the elastic locking block can only rotate into the lanyard buckle ear, and the bottom of the elastic locking block is designed as an arc surface inclined toward the notch.

[0020] The present invention proposes a portable handheld foldable rechargeable fan. Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention is provided with a control module and a battery module. Since the control module and the battery module of the present invention are detachably connected through a convenient disassembly mechanism, and the docking rod cooperates with the docking hole to be positioned by a magnet, and the USB plug and the USB interface realize power transmission, when the battery module is exhausted, the user can quickly replace the battery module with a new one, or directly plug the USB plug of the control module into a power bank for power supply; this design avoids the damage to the battery caused by the traditional fan being charged and used at the same time, and according to tests, the battery life can be extended by more than 50%; at the same time, this design frees the fan from the constraints of the charging cable, and the user can use it flexibly in scenarios such as outdoor camping, commuting, and field work, and the battery life flexibility is improved by 80% compared with traditional fans.

[0022] 2. The present invention is provided with components such as a pressure block and a hanging rope buckle ear. Since the high-speed fan module is rotatably connected to the control module through a connecting seat, when the high-speed fan module rotates 90°, the pressure block on the outer wall of the connecting seat will push the transmission frame, thereby triggering the hanging rope buckle ear to automatically pop out from the buckle ear slot; at this time, the hanging rope can be quickly fixed through the notch at the bottom of the hanging rope buckle ear and the elastic locking block, and the elastic locking block can only rotate into the hanging rope buckle ear, which can effectively prevent the hanging rope from accidentally falling off; this design allows the fan to be hung around the neck for use, greatly freeing up both hands, and is very suitable for scenes where both hands need to be active, such as sports and shopping; and when the hanging rope is not needed, the hanging rope buckle ear will be hidden in the buckle ear slot, ensuring the simple and beautiful appearance of the control module, taking into account both portability and aesthetics.

[0023] 3. The high-speed fan module in the present invention is rotatably connected to the control module through a damping shaft, and can be freely adjusted from 0 to 90 degrees. Users can flexibly adjust the air outlet direction according to their own needs, and can easily achieve both direct blowing and side blowing. In addition, the LED light installed on the outer wall of the air outlet end of the high-speed fan module can also provide lighting function during the use of the fan, so that it has dual purposes of fan and emergency lighting, which is particularly suitable for night scenes such as camping, night running, power outage emergency, etc., greatly improving the functional integration.

[0024] 4. The present invention is provided with components such as docking rods and docking holes. Since the docking rod adopts an I-shaped cross-section design and cooperates with the magnet at the end to position it, it can ensure that the control module and the battery module are firmly connected, and even if shaking occurs during carrying, it can effectively prevent the module from falling off; during disassembly, the user turns the knob to drive the lifting rack down through the driving gear, thereby pushing the battery module and the control module to separate. During this process, the USB plug will first detach from the USB interface, realizing a safe operation of first powering off and then separating, and avoiding damage to the USB interface due to forced pulling; and the design of multiple sets of docking rods and magnets further enhances the vibration resistance of the connection. The entire disassembly and assembly process does not require the aid of additional tools, and a single-person operation only takes about 10 seconds, which not only improves the convenience of use but also ensures safety during use.

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] See also Figure 1-13The present invention provides a technical solution: a portable handheld foldable rechargeable fan, comprising a control module 1, a high-speed fan module 3, and a battery module 4. The battery module 4 is quickly replaced by a convenient detachable mechanism, and a hidden buckle mechanism is combined to improve portability, thereby effectively solving the problems of limited battery life and single usage scenarios of traditional handheld fans.

[0041] Specifically, the top of the control module 1 is rotatably mounted on the connecting base 2 via a damping shaft, while a high-speed fan module 3 is fixed to the outer wall of the connecting base 2, and an LED light 31 is installed on the outer wall of the air outlet end of the high-speed fan module 3. The bottom of the control module 1 is detachably connected to the battery module 4 via a convenient disassembly mechanism, which is used to achieve flexible power supply and quick disassembly and assembly of the module.

[0042] Because the high-speed fan module 3 can achieve free rotation of 0-90° through the damping shaft between the connecting seat 2 and the control module 1, the outer wall of the control module 1 is provided with a control panel 101, which is used to adjust the wind speed gear of the high-speed fan module 3 and the switch and brightness of the LED light 31, thereby meeting the usage requirements of different scenarios such as outdoor and office.

[0043] In this embodiment, multiple sets of docking rods 7 are installed on the bottom end surface of the control module 1, and multiple sets of docking holes 8 corresponding to the docking rods 7 are opened on the top end surface of the battery module 4. Magnets that attract each other are provided at the ends of the docking rods 7 and the docking holes 8. Since the cross-section of the docking rods 7 is in the shape of an "I", the top and bottom outer walls of the docking rods 7 can be closely attached to the walls of the docking holes 8. At the same time, the corners of the outer walls of the docking rods 7 are all beveled to facilitate guidance during insertion.

[0044] It is worth noting that the length of the docking rod 7 is greater than the length of the USB plug 5 at the bottom of the control module 1. This ensures that when the docking rod 7 is inserted into the docking hole 8, the USB plug 5 is inserted into the USB interface 6 on the top of the battery module 4. Finally, precise positioning is achieved through magnetic adsorption to ensure the safety of the power-on process. At the same time, it ensures that the control module 1 and the battery module 4 will not fall off during the movement of the fan, thereby ensuring the stability of the connection.

[0045] In this embodiment, the control module 1 is internally mounted with two sets of lifting racks 9, each having an inverted L-shaped cross-section. The distance between the top and the axis of the drive gear 10 is greater than the length of the docking rod 7. The two sets of drive gears 10 are connected by a transmission shaft 11. When a knob 12 on the outer wall of the control module 1 is turned, the drive gear 10 drives the lifting racks 9 to slide up and down.

[0046] Specifically, when the lifting rack 9 slides down, its bottom will touch the top surface of the battery module 4, thereby starting to push the battery module 4 and the control module 1 to separate; and when the lifting rack 9 slides up, it will release the tight state on the battery module 4, thereby achieving rapid separation of the battery module 4 and the control module 1. Compared with directly pulling the battery module 4 and the control module 1, the probability of damage to the battery module 4, the control module 1 and the high-speed fan module 3 is lower and safer.

[0047] In this embodiment, the high-speed fan module 3 is rotatably connected to the control module 1 through the connecting seat 2, and a pressure block 22 is fixedly installed on the outer wall of the connecting seat 2; and a transmission frame 21 is slidably installed inside the control module 1, the outer end of which protrudes from the outer wall of the control module 1, and the inner wall that is in contact with the transmission wheel 20 is designed as a slope; when the high-speed fan module 3 rotates 90°, the pressure block 22 on the outer wall of the connecting seat 2 will push the transmission frame 21 to slide into the control module 1. At this time, the slope of the transmission frame 21 will squeeze the transmission wheel 20, causing the transmission wheel 20 to rotate and push the hanging rope buckle ear 13, thereby realizing the automatic triggering of the hidden buckle ear mechanism.

[0048] Because the outer wall of the control module 1 in this embodiment is provided with a buckle ear groove 130, and the hanging rope buckle ear 13 is slidably installed in the buckle ear groove 130, and a notch 15 is provided at the outer end of the bottom thereof, and an elastic locking block 14 is rotatably installed in the notch 15 through a torsion spring and a rotating shaft; and the top of the hanging rope buckle ear 13 is fixedly connected to the extension frame 16, and the extension frame 16 is sleeved on the limiting column 18 and connected to the spring 17. At the same time, a T-shaped limiting rod 19 slidably connected to the hanging rope buckle ear 13 is also fixedly installed in the control module 1; when the transmission wheel 20 pushes the hanging rope buckle ear 13, the locking rod 19 is locked. When the rope buckle ear 13 is released, the rope buckle ear 13 will slide outward from the buckle ear slot 130. At this time, the part of the rope buckle ear 13 with the notch 15 is exposed to the control module 1, and the user can pass the hanging rope 131 through the notch 15. Since the end surface of the elastic locking block 14 is in contact with the inner wall of the notch 15 and can only rotate into the rope buckle ear 13, its bottom is an arc surface inclined toward the notch 15, which makes it easy for the hanging rope 131 to squeeze the elastic locking block 14 into the notch 15. After entering, the elastic locking block 14 is reset under the action of the torsion spring, effectively preventing the hanging rope 131 from falling off.

[0049] In this embodiment, a USB interface 6 is provided on the top of the battery module 4, and a charging port 41 is provided on the side wall. The USB plug 5 at the bottom of the control module 1 is connected to the USB interface 6 to realize power supply; when the battery module 4 is exhausted, the knob 12 is turned to make the lifting rack 9 slide down, separate the control module 1 and the battery module 4, and charge the battery module 4 through the charging port 41; at the same time, the user can replace the new battery module 4. This design avoids damage to the battery when charging and using at the same time, and greatly improves the flexibility of battery life.

[0050] The fan achieves stable connection and power-off protection of the battery module 4 through the docking positioning and easy-to-unlock design of the easy-to-detach mechanism; at the same time, the folding linkage and anti-detachment structure of the hidden buckle mechanism are used to improve the portability of the fan; in addition, the modular battery life design and multi-function integration effectively solve the problems of short battery life and limited usage scenarios of traditional handheld fans, providing users with a more flexible and convenient usage experience.

[0051] Working Principle: When the fan is needed, the user holds the control module 1 and adjusts the wind speed and gear position of the high-speed fan module 3 through the control panel 101. Since the high-speed fan module 3 is rotatably connected to the control module 1 via the damping shaft of the connecting seat 2, the user can flexibly adjust the air outlet direction according to their actual needs. Since the outer wall 31 of the air outlet end of the high-speed fan module 3 is installed with an LED light, it can provide lighting as needed, which is also controlled by the control panel 101.

[0052] At the same time, the battery module 4 is connected to the control module 1 through a convenient disassembly mechanism; during actual installation, the docking rod 7 is first inserted into the docking hole 8. Because the length of the docking rod 7 is greater than the length of the USB plug 5, before the docking rod 7 enters the docking hole 8 and starts to support the control module 1, the USB plug 5 will not contact the top surface of the battery module 4, reducing the probability of damage to the USB plug 5. As the docking rod 7 continues to descend, the USB plug 5 is smoothly inserted into the USB interface 6 to realize power supply;

[0053] After installation, the driving gear 10, the lifting rack 9 and the knob 12 in the disassembly mechanism remain stationary, and the disassembly mechanism is in a locked state;

[0054] When the user wants to hang the fan around his neck, he rotates the high-speed fan module 3 90 degrees, causing the pressure block 22 on the outer wall of the connecting base 2 to push the transmission frame 21. Because the outer end of the transmission frame 21 protrudes from the control module 1, and the outer wall thereof in contact with the transmission wheel 20 is designed with an inclined surface, the transmission frame 21 slides into the control module 1 under pressure. At this time, the inclined surface of the transmission frame 21 presses the outer wall of the transmission wheel 20, forcing the transmission wheel 20 to push the hanging rope buckle 13, causing it to slide outward from the buckle groove 130.

[0055] Because the top of the lanyard buckle ear 13 is fixedly connected to the extension frame 16, the extension frame 16 slides along the limiting column 18 and compresses the spring 17;

[0056] When the outer end of the hanging rope buckle ear 13 is exposed, the user can pass the hanging rope 131 through the notch 15 at the bottom of the hanging rope buckle ear 13. During this process, the hanging rope 131 will squeeze the curved surface of the elastic locking block 14, forcing it to start rotating. At this time, the torsion spring is in a stressed state. As the hanging rope 131 enters the hanging rope buckle ear 13 and separates from the elastic locking block 14, the elastic locking block 14 will automatically reset under the action of the torsion spring, closing the notch 15 to prevent the hanging rope 131 from accidentally falling off. When the hanging rope 131 needs to be removed, the notch 15 can be opened by manually pressing the elastic locking block 14, and the hanging rope 131 can be removed.

[0057] When the battery in the battery module 4 is exhausted, the knob 12 is turned, which drives the two sets of drive gears 10 to rotate synchronously through the transmission shaft 11, causing the lifting rack 9 to start sliding downward, which will squeeze the top surface of the battery module 4. Under the action of the thrust, the battery module 4 and the control module 1 are gradually separated; during this process, the end of the docking rod 7 and the magnet at the bottom of the docking hole 8 will separate, and the connection resistance between the battery module 4 and the control module 1 will be greatly reduced. Then, the control module 1 and the battery module 4 can be directly separated manually, or the knob 12 can be continued to be turned to separate the control module 1 and the battery module 4;

[0058] As the distance between the control module 1 and the battery module 4 increases, the USB plug 5 will be separated from the USB interface 6, and the power will be cut off. Then the docking rod 7 will slide out of the docking hole 8, ensuring that the power is cut off before separation. At this time, the charging cable can be inserted into the charging port 41 to charge the battery module 4. At the same time, because the docking rod 7 is longer than the USB plug 5, even if the control module 1 and the battery module 4 are separated, the USB plug 5 will not directly contact other surfaces, further improving the safety of the USB plug 5.

[0059] Then align the docking hole 8 of the battery module 4 with sufficient power with the docking rod 7 and then reverse the operation to assemble the control module 1 and the battery module 4. If the user's two sets of battery modules 4 or multiple sets of battery modules 4 are in a state of insufficient power, the USB plug 5 of the control module 1 can also be directly inserted into the interface of the power bank for power supply to avoid damage to the battery while charging and using.

[0060] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
