Description

Technical Field

[0001] This utility model relates to the field of waist-hanging fan technology, and in particular to a waist-hanging fan with anti-fall-off function. Background Technology

[0002] The waist-mounted fan is a portable cooling device developed for high-temperature environments. It delivers directional airflow by being worn around the waist and is designed for outdoor workers, sports enthusiasts, and daily commuters, combining efficient cooling with portability.

[0003] Waist-mounted fans typically have hooks on the side of the fan to secure it to a belt or waistband. For easy attachment and removal, the hooks are usually open. However, this mounting method has some drawbacks. For example, when the user engages in activities with up-and-down movement, such as running, the fan may gradually rise due to inertia and eventually slip off the belt or waistband.

[0004] To avoid the above situation, this application proposes a waist-mounted fan with anti-fall-off function to reduce the possibility of the waist-mounted fan falling off during exercise. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a waist-hanging fan with an anti-fall-off function to solve the problem that waist-hanging fans in the prior art are prone to falling off during exercise.

[0006] To achieve the above and other related objectives, this utility model provides a waist-mounted fan with an anti-fall-off function, including a blower fan, a human-computer interaction device provided on the outer surface of the blower fan, and a fixing mechanism provided on the outer surface of the human-computer interaction device;

[0007] The human-computer interaction device is used to control the start and stop of the air supply fan;

[0008] The fixing mechanism is used to fix the air supply fan at the waist position;

[0009] The fixing mechanism includes a connecting baffle, which is fixed to the outer surface of the human-computer interaction device by fasteners. The front of the connecting baffle is provided with an elastic clamping plate, a first clamping block is provided at the lower part of the side of the elastic clamping plate facing the connecting baffle, and a second clamping block is provided at the lower part of the side of the connecting baffle facing the elastic clamping plate.

[0010] The first clamping block and the second clamping block are arranged alternately, one above the other.

[0011] Preferably, the top of the second clamping block is provided with a hinge groove, the interior of the hinge groove is provided with a support shaft, and the outer surface of the support shaft is hinged with a resistance anti-disengagement part;

[0012] The top of the resistance and anti-detachment part is inclined towards the direction of the downward elastic clamp.

[0013] Preferably, the resistance anti-detachment part includes a resistance plate, the bottom of which is hinged to the support shaft.

[0014] The top of the resistance plate is provided with a rubber head, and in its natural state, the outer surface of the rubber head is in contact with the inner wall of the elastic clamp.

[0015] Preferably, the side of the rubber head facing the elastic clamp protrudes from the outer surface of the resistance plate, and the outer surface of the rubber head is provided with a plurality of anti-slip teeth.

[0016] Preferably, the connecting baffle and the elastic clamp are both made of antimagnetic material.

[0017] Preferably, a permanent magnet is disposed inside the rubber head;

[0018] The outer surface of the elastic clamp is provided with a sliding groove, and a magnetic switch is installed inside the sliding groove. The magnetic switch can slide up and down in the sliding groove, and the side of the magnetic switch facing the permanent magnet has a magnetic pole that is magnetically repelled by the permanent magnet.

[0019] Preferably, the magnetic switch includes a slider, and a permanent magnet is provided on the side of the slider facing the resistance anti-disengagement part.

[0020] Preferably, limiting grooves are provided at equal intervals on both sides of the sliding button groove;

[0021] The outer surface of the slider is provided with elastic balls at equal intervals on both sides. The elastic balls cooperate with the limiting groove to limit the position of the slider.

[0022] As described above, the waist-mounted fan with anti-fall-off function of this utility model has the following beneficial effects:

[0023] This invention features a first clamping block at the inner bottom of an elastic clamping plate and a second clamping block at the inner bottom of a connecting baffle, with the first and second clamping blocks interlocking. When suspended on a belt or waistband, the interlocking first and second clamping blocks increase the contact area between the elastic clamping plate and the connecting baffle, creating multiple layers of obstruction for the belt. When suspended on the waistband, the waistband is bent, increasing the gripping force and friction, thus avoiding or reducing the risk of the fan falling off during exercise.

[0024] This invention features a hinge groove on the second clamping block, with a resistance plate hinged to the support shaft in the hinge groove, placing the resistance plate in an inclined state. When suspended from a belt or waistband, the rubber head at the end of the resistance plate contacts the belt or waistband. When the fan is lifted by inertia, the belt or waistband pulls the resistance plate downward under friction, increasing the pressure of the rubber head on the inner wall of the elastic clamp and gripping the belt or waistband, preventing the fan from moving upward and further achieving the effect of preventing it from falling off.

[0025] This invention features a permanent magnet 1 inside the rubber head and a slidable permanent magnet 2 on the outer surface of the elastic clamp. In the fixed state, permanent magnet 1 and permanent magnet 2 are misaligned. When the waist fan needs to be removed, permanent magnet 2 is pushed to overlap with permanent magnet 1. The magnetic repulsion between permanent magnet 2 and permanent magnet 1 causes the resistance plate to rotate towards the connecting baffle, thereby reducing the constraint force of the rubber head on the waistband or waistband and achieving the effect of easy disassembly and assembly.

[0026] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value. Attached Figure Description

[0038] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0039] Please see Figures 1 to 8 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0040] like Figure 1 and Figure 2 As shown, this utility model provides a waist-mounted fan with an anti-fall-off function, including a blower fan 1. A human-machine interface device 2 is mounted on the outer surface of the blower fan 1. The human-machine interface device 2 contains a battery and a switch for controlling the start and stop of the blower fan 1. When the switch on the human-machine interface device 2 is turned on, the battery supplies power to the blower fan 1, causing the motor in the blower fan 1 to rotate and blow air onto the body. A fixing mechanism 3 is mounted on the outer surface of the human-machine interface device 2. The fixing mechanism 3 uses its elasticity to control the opening and closing of the opening, thus fixing the blower fan 1 to the waist.

[0041] Specifically, the fixing mechanism 3 includes a connecting baffle 31, which is attached to the outer surface of the human-machine interface device 2. The connecting baffle 31 has a through-hole, through which fasteners fix the fixing mechanism 3 to the outer surface of the human-machine interface device 2. An elastic clamping plate 32 is provided on the front of the connecting baffle 31, and openings are provided at the bottom of both the connecting baffle 31 and the elastic clamping plate 32. When pressure is applied to the openings of the connecting baffle 31 and the elastic clamping plate 32, the bottom of the elastic clamping plate 32 expands outwards, increasing the opening size, allowing a belt or waistband to pass between the connecting baffle 31 and the elastic clamping plate 32. A first clamping block 33 is provided on the lower part of the side of the elastic clamping plate 32 facing the connecting baffle 31, and a second clamping block 34 is provided on the lower part of the side of the connecting baffle 31 facing the elastic clamping plate 32. The first clamping block 33 and the second clamping block 34 are staggered vertically. When suspended on a belt or waistband, the interlocking first clamping block 33 and second clamping block 34 increase the contact area inside the elastic clamping plate 32 and connecting baffle 31, and create multiple layers of obstruction on the belt. When suspended on the waistband, the waistband is bent, increasing the biting force and friction, thus avoiding or reducing the risk of the fan falling off during exercise.

[0042] like Figure 2 and Figure 5 As shown, in some embodiments, the top of the second clamping block 34 of this invention has a hinge groove 341, and a support shaft 342 is provided inside the hinge groove 341. The outer surface of the support shaft 342 is hinged with a resistance anti-slip part 35. Under the action of gravity, the top of the resistance anti-slip part 35 tilts downward toward the elastic clamp 32 and overlaps and abuts against the surface of the waistband or waistband. When the waist fan is lifted by inertia, the waistband or waistband will pull the resistance plate 351 downward to rotate under the action of friction, which increases the pressure of the rubber head 352 on the inner wall of the elastic clamp 32 and bites the waistband or waistband, preventing the waist fan from moving upward and further achieving the effect of preventing slippage.

[0043] like Figure 6As shown, in some embodiments, the resistance anti-slip part 35 of this utility model includes a resistance plate 351, which is made of hard metal. The bottom of the resistance plate 351 is hinged to the support shaft 342, so that the bottom of the resistance plate 351 can rotate about the support shaft 342. A rubber head 352 is provided on the top of the resistance plate 351, which can increase the friction and weight of the top of the resistance plate 351. Under natural gravity, the outer surface of the rubber head 352 is in contact with the inner wall of the elastic clamp 32. When the waistband or waistband is inserted between the connecting baffle 31 and the elastic clamp 32, the rubber head 352 can come into contact with the waistband or waistband. When the waistband fan moves, the rubber head 352 can be better pulled by the waistband or waistband, especially when the waistband fan moves upward, the rubber head 352 is driven by the relative friction to rotate the resistance plate 351 downward. The rubber head 352 is used to squeeze the waistband or waistband to prevent or reduce the movement of the waist fan.

[0044] like Figure 6 As shown, in some embodiments, the side of the rubber head 352 facing the elastic clamp 32 protrudes from the outer surface of the resistance plate 351. Besides increasing the contact area between the rubber head 352 and the belt or waistband, this also changes the center of gravity of the resistance plate 351, allowing the top of the resistance plate 351 to tilt more towards the elastic clamp 32. The outer surface of the rubber head 352 is provided with several anti-slip teeth to improve friction. Simultaneously, the rubber head 352, being made of rubber, can increase friction and prevent damage to the belt or waistband through its own deformation.

[0045] like Figure 3 , Figure 4 and Figure 7 As shown, in some embodiments, a permanent magnet 353 is provided inside the rubber head 352 of this invention, increasing the weight of the rubber head 352 and making the end of the resistance plate 351 magnetic. A sliding groove 321 is formed on the outer surface of the elastic clamp 32, and a magnetic switch 36 is installed inside the sliding groove 321. The magnetic switch 36 is magnetic. The magnetic switch 36 can slide up and down in the sliding groove 321, and the side of the magnetic switch 36 facing the permanent magnet 353 has magnetic poles that repel the permanent magnet 353. When the magnetic switch 36 slides to coincide with the position of the permanent magnet 353, the magnetic repulsion of the magnetic switch 36 will push the permanent magnet 353 to rotate in the opposite direction against the influence of gravity, allowing the waist fan to be easily removed from the belt or waistband. When the magnetic switch 36 is misaligned with the permanent magnet 353, the permanent magnet 353 will only be subjected to a slight magnetic repulsion or will be unaffected and will not come into contact with the belt or waistband.

[0046] It should be noted that the connecting baffle 31 and the elastic clamp 32 of this utility model are both made of antimagnetic material to reduce the influence of the connecting baffle 31 and the elastic clamp 32 on the permanent magnet 353 and the magnetic control switch 36.

[0047] like Figure 8 As shown, in some embodiments, the magnetic control switch 36 of this utility model includes a slider 361. The plastic block of the slider 361 has a groove on the side facing the resistance anti-disengagement part 35. A second permanent magnet 363 is disposed inside the groove of the slider 361, and the magnetic poles of the second permanent magnet 363 and the first permanent magnet 353 repel each other.

[0048] like Figure 4 and Figure 8 As shown, in some embodiments, the sliding groove 321 of the present invention is provided with limiting grooves 322 at equal intervals on both sides, and the limiting grooves 322 are semi-circular grooves.

[0049] Elastic balls 362 are equidistantly arranged on both sides of the outer surface of the slider 361. The elastic balls 362 cooperate with the limiting groove 322 to limit the position of the slider 361. The elastic balls 362 are elastic; when compressed, they retract into the interior of the slider 361. This allows the slider 361 to be positioned after being pushed to move. To further improve the stability of the slider 361, concave grooves can be provided on both sides of the slider groove 321, making the slider groove 321 T-shaped. Extending wings are provided at the bottom of the sides of the slider 361, extending into the concave grooves, preventing the slider 361 from detaching from the interior of the slider groove 321.

[0050] In summary, the waist-hanging fan with anti-fall function of this utility model, by setting a first clamping block 33 at the inner bottom of the elastic clamping plate 32 and a second clamping block 34 at the inner bottom of the connecting baffle 31, and making the first clamping block 33 and the second clamping block 34 interlock, when hanging on a belt or waistband, the interlocking first clamping block 33 and the second clamping block 34 can increase the contact area inside the elastic clamping plate 32 and the connecting baffle 31, and form multiple layers of obstruction for the belt. When hanging on the waistband, the waistband is bent, increasing the biting force and friction, thereby avoiding or reducing the risk of the waist-hanging fan falling off during exercise.

[0051] This invention features a hinge groove 341 on the second clamping block 34, and a resistance plate 351 is hinged to the support shaft 342 in the hinge groove 341, so that the resistance plate 351 is in an inclined state. When it is suspended on the waistband and waistband, the rubber head 352 at the end of the resistance plate 351 will contact the waistband or waistband. When the waist fan is lifted by inertia, the waistband or waistband will pull the resistance plate 351 downward under the action of friction, so that the pressure of the rubber head 352 on the inner wall of the elastic clamp 32 increases and bites the waistband or waistband, preventing the waist fan from moving upward and further achieving the effect of preventing it from falling off.

[0052] This invention features a permanent magnet 353 inside the rubber head 352 and a slidable permanent magnet 363 on the outer surface of the elastic clamp 32. In the fixed state, the permanent magnet 353 and the permanent magnet 363 are misaligned. When the waist fan needs to be removed, the permanent magnet 363 is pushed to overlap with the permanent magnet 353. The magnetic repulsion between the permanent magnet 363 and the permanent magnet 353 causes the resistance plate 351 to rotate towards the connecting baffle 31, thereby reducing the constraint force of the rubber head 352 on the waist belt or waistband and achieving the effect of easy disassembly and assembly.

[0053] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0054] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
