Description

Technical Field

[0001] This utility model relates to the field of handheld fan technology, specifically a handheld fan for applying ice. Background Technology

[0002] As living standards improve, convenient personal cooling devices are gradually gaining popularity among consumers. Especially in the hot summer, handheld fans have become a common portable cooling tool. However, existing handheld fan products only have a single blowing function, which is relatively limited and cannot meet the needs of users. Utility Model Content

[0003] This utility model addresses the technical problems existing in the prior art by providing a handheld fan for cooling, which solves the problem that existing handheld fans only have a single blowing function, making them relatively simple and unable to meet the needs of users.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A handheld fan for ice application, comprising: A fan body, the fan body including a mesh cover; A handle, wherein the handle is disposed at the bottom of the mesh cover; A semiconductor cooling chip, wherein the semiconductor cooling chip is centrally disposed on one side of the mesh cover; A metal sheet, the metal sheet being disposed on one side of a semiconductor cooling chip; A clamping assembly is provided on either side of the handle. The clamping assembly includes a back plate and two clamps. The back plate is detachably connected to either side of the handle. The two clamps are movable on both sides of the back plate and can move in opposite directions.

[0005] The beneficial effects of this utility model are: 1) A combined cooling structure of a semiconductor cooling chip and a metal plate is centrally located on one side of the mesh cover. The thermoelectric effect of the semiconductor cooling chip can actively cool the metal plate. During use, the user can bring their skin close to the metal plate to feel the cooling effect, thereby relieving body heat and improving the cooling effect and user comfort. On the other hand, clamping components can be installed on both sides of the handle. These components include a back plate and a clamping structure with bidirectional displacement. When the back plate is installed on the blowing side of the handle, the clamp can hold electronic devices such as mobile phones to achieve rapid heat dissipation. When the back plate is installed on the non-blowing side of the handle, the clamp can hold and fix the handle to other objects to limit the handle's position, thereby freeing the user's hands. This device not only solves the problem of traditional fans requiring long-term hand holding, but also achieves active heat dissipation for electronic devices, improving the product's practicality and user experience.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the clamping assembly also includes a Phillips head bolt, two positioning pins, and two sets of connecting structures. The two sets of connecting structures are respectively located on both sides of the handle. Each set of connecting structures includes a countersunk hole with internal threads and two positioning holes. The two positioning holes are spaced apart on the outside of the handle, and the countersunk hole is located between the two positioning holes and is located on the outside of the handle.

[0008] Furthermore, one end of the plum blossom hand-tightening bolt passes through the back plate and is screwed into the countersunk hole through the thread, one end of each of the two positioning pins is fixed to one side of the back plate, and the other end of each of the two positioning pins is inserted into the two positioning holes respectively.

[0009] The beneficial effects of adopting the above-mentioned further solution are that by setting two positioning pins and corresponding positioning holes for precise matching, the back plate can be quickly positioned and prevented from rotating during the installation process. At the same time, the threaded connection between the plum blossom hand-tightening bolt and the internal thread countersunk hole provides reliable fastening force, allowing the back plate to be firmly fixed to the outside of the handle, thereby completing the installation of the back plate. The plum blossom-shaped hand-tightening structure makes it easy for users to operate by hand, and can complete the disassembly and assembly without additional tools.

[0010] Furthermore, each of the clamps includes a clamping plate, a sliding rod, a movable groove, a locking slot, a locking plate, and a spring. The movable groove is formed inside one side of the back plate, the locking slot is formed outside the back plate and coaxially communicates with the movable groove, the spring abuts against the side wall of the movable groove and is located inside the movable groove, one end of the sliding rod penetrates the spring and the movable groove and extends to the outside of the back plate, and the locking plate is coaxially fixed to the other end of the sliding rod.

[0011] Furthermore, the clamp is fixed to one end of the slide bar that extends beyond the back plate.

[0012] Furthermore, the diameter of the slot is smaller than the diameter of the movable slot.

[0013] Furthermore, the outer diameter of the spring is larger than the diameter of the slot.

[0014] Furthermore, the diameter of the card plate is larger than the outer diameter of the spring.

[0015] The beneficial effect of adopting the above-mentioned further solution is that, since the diameter of the clamping plate is larger than the outer diameter of the spring, and the spring abuts against the side wall of the movable groove, when the slide bar is pulled outward to make the two clamping plates move in opposite directions, the clamping plate abuts against one side of the spring and retracts the spring. At this time, the two clamping plates are respectively subjected to the elastic preload of the spring in opposite directions, which can realize the clamping of the mobile phone, or clamping it to other objects to fix the handle.

[0016] Furthermore, rectangular limiting grooves are provided on both sides of the bottom of the handle, and the handle is rotatably connected to the side wall of the limiting groove via a rotating shaft.

[0017] The beneficial effect of adopting the above-mentioned further solution is that, since the ring buckle is rotatably connected in the side wall of the limiting groove, the ring buckle is effectively constrained by the side wall of the limiting groove during rotation, allowing the ring buckle to rotate only within a 90-degree range. When the ring buckle rotates to a horizontal position perpendicular to the handle, it can provide stable support for the entire fan body, realize the horizontal placement function of the fan, and meet the user's desktop usage needs.

[0020] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0021] With the improvement of living standards, convenient personal cooling devices have gradually become popular among consumers. Especially in the hot summer, handheld fans have become a common portable cooling tool. However, existing products only have a single blowing function, which is relatively simple and cannot meet the needs of users. In response, the inventor of this utility model proposes an ice-packing handheld fan to solve the above problems.

[0022] The present invention provides the following preferred embodiments. like Figures 1-9 As shown, a handheld cooling fan includes: Fan body 10, the fan body 10 includes a mesh cover 101; Handle 20, handle 20 is located at the bottom of the mesh cover 101 A semiconductor cooling chip 30 is centrally positioned on one side of the mesh cover. Metal sheet 70 (metal sheet 70 may be made of copper) is disposed on one side of semiconductor cooling chip 30; The clamping assembly 40 is disposed on either side of the handle 20. The clamping assembly 40 includes a back plate 420 and two clamps 410. The back plate 420 is detachably connected to either side of the handle 20. The two clamps 410 are movable on both sides of the back plate 420 and can move in opposite directions. A combined cooling structure of a semiconductor cooling chip 30 and a metal plate 70 is centrally located on one side of the mesh cover 101. The thermoelectric effect of the semiconductor cooling chip 30 can be used to actively cool the metal plate 70. During use, the user can bring their skin close to the metal plate 70 to feel the cooling effect, thereby relieving the body's heat and improving the cooling effect and user comfort. On the other hand, clamping components 40 can be installed on both sides of the handle 20. These components include a back plate 420 and a clamping structure 410 with bidirectional displacement. When the back plate 420 is installed on the blowing side of the handle 20, the clamping device 410 can hold electronic devices such as mobile phones to achieve rapid heat dissipation. When the back plate 420 is installed on the non-blowing side of the handle 20, the clamping device 410 can hold and fix the handle 20 to other objects to limit the position of the handle 20, thereby freeing the user's hands. This device not only solves the problem of traditional fans requiring long-term hand holding, but also achieves active heat dissipation for electronic devices, improving the practicality of the product and the user experience.

[0023] In this embodiment, as Figures 1-9As shown, the clamping assembly 40 also includes a Phillips head bolt 430, two positioning pins 440 and two sets of connecting structures 450. The two sets of connecting structures 450 are respectively disposed on both sides of the handle 20. Each set of connecting structures 450 includes a countersunk hole 451 with internal threads and two positioning holes 452. The two positioning holes 452 are spaced apart on the outside of the handle 20. The countersunk hole 451 is located between the two positioning holes 452 and is disposed on the outside of the handle 20. One end of the Phillips head bolt 430 passes through the back plate 420 and is screwed into the countersunk hole 451 by threads. One end of each of the two positioning pins 440 is fixed to one side of the back plate 420, and the other end of each of the two positioning pins 440 is inserted into the two positioning holes 452. By setting two positioning pins 440 and corresponding positioning holes 452 for precise matching, the back plate 420 is quickly positioned and anti-rotation is achieved during installation. At the same time, the threaded connection between the plum blossom hand-tightening bolt 430 and the internal thread countersunk hole 451 provides reliable fastening force, allowing the back plate 420 to be fastened to the outside of the handle 20, thereby completing the installation of the back plate 420. The plum blossom-shaped hand-tightening structure makes it easy for users to operate by hand, and disassembly and assembly can be completed without additional tools.

[0024] In this embodiment, as Figures 1-9 As shown, each clamp 410 includes a clamping plate 411, a sliding rod 412, a movable groove 413, a slot 414, a clamping plate 415, and a spring 416. The movable groove 413 is formed inside one side of the back plate 420, and the slot 414 is formed outside the back plate 420 and coaxially communicates with the movable groove 413. The spring 416 abuts against the side wall of the movable groove 413 and is located inside the movable groove 413. One end of the sliding rod 412 penetrates the spring 416 and the movable groove 413 and extends to the outside of the back plate 420. The clamping plate 415 is coaxially fixed to the other end of the sliding rod 412. The clamping plate 411 is fixed to the end of the sliding rod 412 that extends to the outside of the back plate 420. The outer diameter of the spring 416 is larger than the diameter of the slot 414, and the diameter of the clamping plate 415 is larger than the outer diameter of the spring 416. Since the diameter of the clamping plate 415 is larger than the outer diameter of the spring 416, and the spring 416 abuts against the side wall of the movable groove 413, when the slide bar 412 is pulled outward to make the two clamping plates 411 move in opposite directions, the clamping plate 415 abuts against one side of the spring 416 and retracts the spring 416. At this time, the two clamping plates 411 are respectively subjected to the elastic preload of the spring 416 in opposite directions, which can achieve the clamping of the mobile phone, or clamping to other objects to fix the handle 20.

[0025] In this embodiment, as Figures 1-9As shown, rectangular limiting grooves 50 are provided on both sides of the bottom of the handle 20, and a ring 60 is rotatably connected to the side wall of the limiting groove 50 via a pivot. Since the ring 60 is rotatably connected in the side wall of the limiting groove 50, the ring 60 is effectively constrained by the side wall of the limiting groove 50 during rotation, allowing the ring 60 to rotate only within a 90-degree range. When the ring 60 rotates to a horizontal position perpendicular to the handle 20, it can provide stable support for the entire fan body 10, realize the horizontal placement function of the fan, and meet the user's desktop use needs.

[0026] The specific working process of this utility model is as follows: (1) Heat dissipation from the human body The thermoelectric effect of the semiconductor cooling chip 30 of model TES1-7102 is used to actively cool the metal plate 70. During use, the user can put their skin (such as the skin of the face or arm) close to the metal plate 70 to feel the cooling effect, thereby relieving the body's heat. Finally, the airflow of the fan body 10 is blown onto the human skin.

[0027] (2) Mobile phone heat dissipation First, install the back plate 420 onto the blower side of the handle 20, that is, insert the positioning pin 440 into the positioning hole 452, and then tighten the Torx screw 430. At the same time, pull the slide bar 412 outward to make the two clamping plates 411 move in opposite directions. At this moment, the two clamping plates 411 are respectively subjected to the elastic preload of the spring 416 in opposite directions. Then, place the mobile phone between the clamping plates 411 to complete the clamping of the mobile phone. Subsequently, the blowing airflow blows towards the mobile phone, which can quickly dissipate heat from the mobile phone.

[0028] (3) Place the handle in a horizontal position 20 Since the ring 60 is rotatably connected in the side wall of the limiting groove 50, the ring 60 is effectively constrained by the side wall of the limiting groove 50 during rotation, allowing the ring 60 to rotate only within a 90-degree range. When the ring 60 rotates to a horizontal position perpendicular to the handle 20, it can provide stable support for the entire fan body 10, realizing the horizontal placement function of the fan.

[0029] (4) Fix the handle 20 First, install the back plate 420 onto the non-blowing side of the handle 20, that is, insert the positioning pin 440 into the positioning hole 452, then tighten the Torx screw 430, and then place the clamped object (including but not limited to the headboard or table and objects that can be placed between the clamping plates 411) between the clamping plates 411. Then, use the elastic pre-tightening force of the spring 416 to limit the clamping plates 411 and the handle 20 to the clamped object, such as the headboard or table, thereby freeing the user's hands and eliminating the need for hand-held operation.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
