Description

Technical Field

[0001] This utility model relates to the field of fan technology, specifically a waist-mounted fan. Background Technology

[0002] In the hot summer, people often use air conditioners and fans to cool down. However, these cooling devices are only convenient for indoor use. When people go out or rest outdoors, they can only rely on fans or natural wind to cool down, which has a very weak cooling effect. Therefore, various portable fans have appeared on the market to meet people's cooling needs outdoors, such as neck fans and waist fans.

[0003] Existing waist-hanging fans can only be hung on the waist. Due to the lack of a support device, they cannot be placed on a table when the user is sitting and resting. Furthermore, when hung on the waist, if the user moves significantly, the fan is prone to falling and damaging itself, reducing its lifespan and providing a poor user experience. To overcome these shortcomings, existing technology (Chinese patent application number 202223028590.8, application date 2022-11-15) provides a portable waist-hanging fan that, through the use of a hanging buckle and a support block, allows the waist-hanging fan to not only retain the waist but also... While it fulfills the basic function of being worn on the waist for work, it can also be placed on a table for operation, improving its practicality. The addition of a protective cover provides good protection for the fan, preventing damage from falls and enhancing user experience. However, the structure relies solely on a hinged support block to hold the fan upright, resulting in limited stability and making the fan prone to tipping over, thus affecting usability. Furthermore, the hook end presses against the user's waist, causing discomfort and impacting the overall user experience.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on existing equipment. Therefore, we have proposed a waist-mounted fan that can effectively solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a waist-mounted fan to solve the problems mentioned in the background art. The structure of the above-mentioned waist-mounted fan is only supported by a hinged support block, which has poor support stability, making the fan easy to tip over and affecting its use. It is not very practical. In addition, the structure of the hook end face will press against the user's waist, causing discomfort and affecting the user's experience.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waist-hanging fan, comprising a fan housing, a fan body installed inside the fan housing, and a waist-hanging buckle and a hem support fixedly connected to the outer walls of both ends of the fan housing, with the waist-hanging buckle and hem support installed in opposite directions; a fixing seat is formed on the end face of the waist-hanging buckle, and a rotating bracket is installed on the inner side of the fixing seat through an elastic connector; a rubber tube is fixedly bonded to the bottom outer wall of the rotating bracket, and the surface of the rubber tube is rough; a pad is provided at one end of the waist-hanging buckle, and the pad covers the surface of the fixing seat and the rotating bracket; a first end rod and a second end rod are fixedly connected to the bottom and top ends of the pad, respectively; a support seat is formed on the bottom wall of the waist-hanging buckle, and the first end rod is rotatably connected to the inner side of the support seat, and the first end rod is axially fixed by a limiting component; a plurality of annular buckles are formed on the top of the waist-hanging buckle, and the second end rod is snapped into the inner side of the annular buckles.

[0007] Preferably, the elastic connector between the fixed base and the rotating bracket is a high-strength torsion spring, so as to achieve stable support of the fan housing by the rotating bracket while the fixed base and the rotating bracket can rotate.

[0008] Preferably, the rotating bracket is attached to the end face of the waist buckle via a pressing assembly. The pressing assembly includes a fixing rod fixedly connected to the end face of the waist buckle. A pressing buckle is slidably connected to the outside of the fixing rod, and a first spring is fixedly connected between the pressing buckle and the fixing rod. The pressing buckle presses against the rubber tube of the rotating bracket.

[0009] Preferably, the pressing end face of the snap fastener and the rubber tube has an arc-shaped structure to increase pressing stability.

[0010] Preferably, the top wall of the waist buckle is formed with multiple protruding fins, which can quickly dissipate the heat generated by the fan body during operation. The protruding fins are provided with slots, and an annular buckle is formed inside the slots.

[0011] Preferably, the limiting component includes a sliding sleeve sleeved on the outside of one side of the first end rod, and a second spring is fixedly connected between the inner wall of the sliding sleeve and the first end rod. The outer wall of the sliding sleeve is formed with a limiting block, and the outer wall of the support seat is provided with a limiting groove that matches the structure of the limiting block. The limiting block of the sliding sleeve is inserted into the inner side of the limiting groove.

[0012] Preferably, an elliptical rod is fixedly connected to the inner wall of the sliding sleeve, the elliptical rod is located inside the second spring and its end is inserted into the first end rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This type of waist-hanging fan, through the elastic connection of the rotating bracket to the waist buckle and the addition of a rubber tube, makes the rotating bracket and the waist buckle at a certain angle, thus forming a stable support structure, thereby making the waist-hanging fan less likely to tip over when placed and used, and enhancing the practicality of the device; by covering the fixed seat and the rotating bracket with a pad and fixing the two ends of the pad, the discomfort caused by the fixed seat and the rotating bracket pressing against the user's waist can be eliminated, thereby improving the user's user experience. The specific contents are as follows: (1) The rotating bracket is elastically connected to the end face of the waist buckle through the fixed seat, so that the rotating bracket and the waist buckle at a certain angle can form a stable support structure, and the setting of the rubber tube can increase the friction between the rotating bracket and the table surface, thereby further increasing the support stability, making the waist-hanging fan less likely to tip over when placed and used, and enhancing the practicality of the device.

[0014] (2) By setting up a pressing component, the first spring pushes the pressing buckle to make it firmly pressed onto the rotating bracket, so that the user can hang the device on the waist for use. When the pressing buckle is pushed down, the rubber tube undergoes elastic deformation and can disengage from the pressing contact with the pressing buckle, so that the fan can be used on the table.

[0015] (3) By covering the fixed seat and rotating bracket with a pad, and fixing the first end rod and the second end rod at both ends of the pad with a support seat, a limiting component and a ring buckle respectively, the discomfort caused by the fixed seat and rotating bracket pressing against the user's waist can be eliminated, thereby improving the user's experience.

[0016] (4) When the pad needs to be folded up to stand the fan upright, first pry the second end rod out of the ring buckle, and then move the sliding sleeve outward so that the limiting block comes out of the limiting groove. At this time, rotate the sliding sleeve to drive the first end rod to rotate synchronously, so that the pad is rolled up to the outside of the first end rod. When it is rolled up to the limit, release the sliding sleeve, and the second spring rebounds to drive the limiting block to be re-inserted into the limiting groove, thus achieving axial fixation of the first end rod to ensure roll-up fixation.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figures 1-6 The present invention provides the following technical solution: a waist-hanging fan, including a fan housing 1, a fan body 2 installed inside the fan housing 1, and waist buckles 3 and hem supports 4 fixedly connected to the outer walls of both ends of the fan housing 1, and the waist buckles 3 and hem supports 4 are installed in opposite directions; a fixing seat 5 is formed on the end face of the waist buckle 3, and a rotating bracket 6 is installed on the inner side of the fixing seat 5 through an elastic connector, wherein the elastic connector is a strong torsion spring, so as to achieve stable support of the fan housing 1 by the rotating bracket 6 under the premise that the fixing seat 5 and the rotating bracket 6 can rotate; and a rubber tube 21 is fixedly bonded to the bottom outer wall of the rotating bracket 6, and the surface of the rubber tube 21 is rough.

[0026] The rotating bracket 6 is elastically connected to the end face of the waist buckle 3 by the fixed base 5, so that the rotating bracket 6 and the waist buckle 3 are at a certain angle. At this time, the fan shell 1 is placed on the table, and the bottom of the rotating bracket 6 is pressed against the table, thus forming a stable support structure. Furthermore, the rubber tube 21 increases the friction between the rotating bracket 6 and the table, thereby further increasing the support stability and making the waist fan less likely to tip over when placed and used, thus enhancing the practicality of the device.

[0027] In addition, the rotating bracket 6 is attached to the end face of the waist buckle 3 by a pressing component. The pressing component includes a fixing rod 7 fixedly connected to the end face of the waist buckle 3. A pressing buckle 9 is slidably connected to the outside of the fixing rod 7, and a first spring 8 is fixedly connected between the pressing buckle 9 and the fixing rod 7. The pressing buckle 9 is pressed onto the rubber tube 21 of the rotating bracket 6. The pressing end face of the pressing buckle 9 and the rubber tube 21 is an arc-shaped structure to increase the pressing stability. The pressing buckle 9 is pressed firmly onto the rotating bracket 6 by the first spring 8, so that the user can hang the device on the waist for use. When the pressing buckle 9 is pushed down, the rubber tube 21 undergoes elastic deformation and can disengage from the pressing contact with the pressing buckle 9. At this time, the strong torsion spring twists back, causing the rotating bracket 6 and the waist buckle 3 to form an angle, so that it can be used upright on the table.

[0028] Example 2: Based on Example 1, a pad 10 is provided at one end of the waist buckle 3, and the pad 10 covers the surface of the fixed base 5 and the rotating bracket 6. The bottom and top ends of the pad 10 are respectively fixedly connected to a first end rod 11 and a second end rod 12. The bottom wall of the waist buckle 3 is formed with a support base 13, and the first end rod 11 is rotatably connected to the inner side of the support base 13. The first end rod 11 is axially fixed by a limiting component. The top of the waist buckle 3 is formed with several annular buckles 15, and the second end rod 12 is snapped into the inner side of the annular buckles 15. By covering the fixed base 5 and the rotating bracket 6 with the pad 10, and fixing the two ends of the pad 10 with the support base 13 and the annular buckles 15, the discomfort caused by the fixed base 5 and the rotating bracket 6 pressing against the user's waist can be eliminated, thereby improving the user's experience.

[0029] The top wall of the waist buckle 3 is formed with multiple protruding fins 14, which can quickly dissipate the heat generated by the fan body 2 during operation. The protruding fins 14 have slots, and the annular buckle 15 is formed inside the slots. By pressing the second end rod 12 against the opening of the annular buckle 15 and pressing it inward, the annular buckle 15 expands outward from the slot, and the second end rod 12 can be easily engaged with the inside of the annular buckle 15, thereby achieving quick fixation of the top of the pad 10.

[0030] The limiting assembly includes a sliding sleeve 16 sleeved around the outside of one side of the first end rod 11, and a second spring 18 is fixedly connected between the inner wall of the sliding sleeve 16 and the first end rod 11. A limiting block 19 is formed on the outer wall of the sliding sleeve 16, and a limiting groove 20 matching the structure of the limiting block 19 is provided on the outer wall of the support base 13. The limiting block 19 of the sliding sleeve 16 is inserted into the inner side of the limiting groove 20. Through the limiting insertion of the limiting block 19 into the limiting groove 20, the axial fixation of the sliding sleeve 16 and the support base 13 can be achieved, that is, the axial fixation of the first end rod 11 and the waist buckle 3 can be achieved, thereby ensuring the axial fixation of the first end rod 11 and the waist buckle 3. The bottom of the pad 10 is fixed, and when the pad 10 needs to be folded up to stand the fan upright, the second end rod 12 can be pried out of the annular buckle 15 first, and then the sliding sleeve 16 is moved outward so that the limiting block 19 is dislodged from the limiting groove 20. The second spring 18 is stretched, and the sliding sleeve 16 can be rotated to drive the first end rod 11 to rotate synchronously. The pad 10 will gradually roll up to the outside of the first end rod 11. When it is rolled up to the limit, the sliding sleeve 16 is released, and the second spring 18 rebounds to drive the limiting block 19 to be re-inserted into the limiting groove 20, thus achieving the axial fixation of the first end rod 11 to ensure the roll-up fixation.

[0031] In addition, an elliptical rod 17 is fixedly connected to the inner wall of the sliding sleeve 16. The elliptical rod 17 is located inside the second spring 18 and its end is inserted into the first end rod 11. Through the structural arrangement of the elliptical rod 17, the first end rod 11 and the sliding sleeve 16 can be axially fixed, thereby achieving the effect of rotating the sliding sleeve 16 to drive the first end rod 11 to rotate synchronously to roll up the pad 10.
