Description

Technical Field

[0001] This utility model relates to the field of fan technology, and specifically to a fan with an ice-cooling function. Background Technology

[0002] A fan is a device used to generate airflow and cool down in hot weather. An electric fan is a device that uses electricity to drive airflow. When the fan blades inside are powered, they rotate, converting mechanical energy into wind energy, which is then transformed into natural wind to achieve a cooling effect.

[0003] In summer, people often use electric fans at home. There are many types of electric fans, such as ceiling fans, table fans, and wall fans. To meet the needs of different occasions, different types of electric fans have also emerged, such as electric fans with clips, which can be clipped to bedside, shelves, clothes, and other places.

[0004] For example, Chinese utility model application No. 202321444326.4 discloses a clip-on fan with a PCB board located at the bottom, including a clip-on base, a support and adjustment assembly, and a fan assembly. The clip-on base includes a top plate, a bottom plate, a support leg, a mounting frame, and a power supply assembly. The top plate is disposed above the bottom plate, and the bottom plate and the top plate are hinged together by the support leg with a torsion spring. One end of the bottom plate and the top plate are free ends that are in contact with each other, and the other end of the bottom plate and the top plate are free ends that are not in contact with each other. The mounting frame is provided on the bottom plate. This clip-on fan with the PCB board located at the bottom, and the power supply assembly is disposed on the bottom plate, can reduce the wind-blocking area of ​​the fan while ensuring a low center of gravity for the overall device, which can greatly improve its ventilation effect and meet people's needs. At the same time, a large-capacity battery can be installed in a small volume to ensure the device's battery life.

[0005] None of the aforementioned fans have an ice-cooling function. Furthermore, since the fan assembly is installed inside the support and adjustment assembly, which in turn is installed on the clip-on base, and the size of the support and adjustment assembly is larger than that of the fan assembly, the overall size is large, making it inconvenient to carry and use.

[0006] For example, utility model application number 202320725594.7 discloses a novel clip fan, including a fan body, a clip base, and a U-shaped bracket supporting the fan body on the clip base. A wire passage is formed within the U-shaped bracket. The fan body can rotate vertically relative to the U-shaped bracket, and the U-shaped bracket can rotate horizontally relative to the clip base. An installation cavity is formed within the clip base, housing a control circuit board, operation buttons, and a battery. The battery is located vertically at the center of gravity of the entire clip fan. By placing the battery in the clip base, a larger and higher-capacity battery can be installed without affecting the fan's airflow. It also facilitates the placement of buttons on the clip base for easy operation. Furthermore, the clip fan's center of gravity is downward, allowing it to be placed on a table for use. The rotation angle is limited by the stop protrusions and connecting blocks, preventing wire tangling during 360° rotation.

[0007] None of the aforementioned fans have an ice-cooling function. Furthermore, since the fan body is installed inside a U-shaped bracket, which is then mounted on a clip base, and the size of the U-shaped bracket is larger than the size of the fan body, the overall size is large, making it inconvenient to carry and use.

[0008] In conclusion, both of the aforementioned fans lack an cooling function, making them inconvenient to use. Furthermore, both fans are bulky and difficult to carry, thus failing to meet consumer requirements. Utility Model Content

[0027] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0028] See Figure 1-6 As shown, a fan with an ice-cooling function includes a fan assembly 1, a power supply assembly 2 for supplying power to the fan assembly 1, and a clip assembly 3.

[0029] The fan assembly 1 includes: a housing 11 with an air inlet 101 and an air outlet 102; a motor assembly 12 installed inside the housing 11 and electrically connected to a power supply assembly 2; and fan blades 13 installed on the motor assembly 12 and driven by the motor assembly 12 to rotate. During rotation, the fan blades 13 draw in outside air from the air inlet 101, accelerate it into wind, and then blow it out from the air outlet 102; this is the function of a conventional fan. Furthermore, in use, this invention can be clipped onto clothing or a backpack using the clip assembly 3, allowing it to be used while the consumer is moving, achieving the purpose of blowing air and cooling without needing to hold it, making it extremely convenient to use.

[0030] To enhance the functionality of this invention, the following design is incorporated: the outer casing 11 is provided with a cooling plate 14 electrically connected to the power supply component 2, and a metal sheet 15 fitted and mounted on the upper surface of the cooling plate 14 for cooling application. The metal sheet 15 is fixed to the surface of the outer casing 11, and its surface protrudes beyond the surface of the outer casing 11. This invention provides a metal sheet 15 protruding beyond the surface of the outer casing 11 and a cooling plate 14 fitted and mounted to the metal sheet 14. When the cooling plate 14 is in operation, it cools and transfers the cold to the metal sheet 15, lowering the overall temperature of the metal sheet 15. This allows it to come into contact with human skin, achieving the function of ice application. This design is more appealing to consumers in hot summers and meets the usage requirements of different consumers.

[0031] In this embodiment, the metal sheet 15 is a stainless steel sheet. The cooling chip 14 is a TEC semiconductor cooling chip.

[0032] The specific installation positions of the cooling element 14 and the outer shell 11 are as follows: the cooling element 14 is disposed in the upper middle part of the outer shell 11, and the metal sheet 15 is disposed in the middle part of the upper surface of the outer shell 11. Multiple air inlets 101 are arranged in a ring-shaped, spaced distribution on the upper surface of the outer shell 11, located around the metal sheet 15. The air outlet 102 is disposed on the outer side of the outer shell 11. This utility model achieves axial air intake and circumferential air exhaust, thus allowing for better control of the air outlet 102 towards the human head after being clamped onto clothing or a backpack by the clip assembly 3, thereby blowing air onto the human head to achieve a cooling effect and making it more convenient to use.

[0033] The specific installation structure of the cooling element 14 and the outer casing 11 is as follows: A limiting groove 111 is provided on the upper surface of the outer casing 11, and an inlay groove 112 is provided on the bottom surface of the limiting groove 111; a downwardly extending annular limiting portion 151 is formed around the metal sheet 15, and several positioning pins 152 are integrally formed at the lower end of the annular limiting portion 151. The annular limiting portion 151 is positioned in the limiting groove 111 from top to bottom, and is inserted and fixed in the inlay groove 112, thus fixing the metal sheet 15 to the upper surface of the outer casing 11. The assembly structure is simple and easy to install. The height of the annular limiting portion 151 is greater than the depth of the limiting groove 111, causing the upper surface of the metal sheet 15 to protrude beyond the upper surface of the outer casing 11.

[0034] The specific assembly structure of the cooling chip 14 is as follows: The upper middle part of the outer shell 11 is provided with an installation window 113 that runs through the upper and lower end faces. The cooling chip 14 is embedded in the installation window 113, and an aluminum base 16 is fixedly installed inside the outer shell 11 by a first screw. The lower end of the cooling chip 14 is attached to the upper end face of the aluminum base 16, that is, the cooling chip 14 is clamped and fixed between the metal sheet 15 and the aluminum base 16.

[0035] The aluminum base 16 is placed above the fan blade 13, and the outer edge of the aluminum base 16 is formed with a plurality of aluminum sheets 161. An interval is formed between two adjacent aluminum sheets 161 to cooperate with the air inlet 101, which can better achieve heat dissipation and improve the cooling efficiency of the cooling chip.

[0036] The specific structure of the outer shell 11 is as follows: the outer shell 11 includes a base 114 and a housing 115 mounted on the base 114.

[0037] The cooling element 14 and the metal sheet 15 are both disposed on the upper end of the housing 115; the air inlet 101 is disposed on the upper end face of the housing 115, and the air outlet 102 is disposed on the outer side of the housing 115; the power supply component 2 is installed on the lower end of the base 114, the motor component 12 and the fan blade 13 are installed on the upper end of the base 114, and the housing 115 covers the periphery of the motor component 12 and the fan blade 13.

[0038] The base 114 is also provided with a C-shaped first air guide wall 103, which has a first air guide port 104 corresponding to the air outlet 102. The fan blade 13 is placed at least at its lower part inside the first air guide wall 103. The housing 115 is also provided with a C-shaped second air guide wall 105 corresponding to the first air guide wall 103. The second air guide wall 105 has a second air guide port 106 corresponding to the air outlet 102. The fan blade 13 is placed at least at its upper part inside the second air guide wall 105. The second air guide wall 105 is connected to the first air guide wall 103, and the second air guide port 106 is connected to and communicates with the first air guide port 104. As a result, all the air generated by the fan blade 13 during rotation is blocked by the first air guide wall 103 and the second air guide wall 105, and guided to the air outlet 102 by the first air guide port 104 and the second air guide port 106, thereby forming a high-speed wind that blows farther and has a better heat dissipation effect.

[0039] The base 114 has a second air inlet 100 at its bottom. The second air inlet 100 is connected to the outside through the gap between the fan assembly 1 and the power supply assembly 2, which can enable air intake and enhance air volume and wind speed.

[0040] The fan assembly 1 and the power supply assembly 2 are cylindrical, and the fan assembly 1, the power supply assembly 2 and the clip assembly 3 are installed sequentially from top to bottom. The outer diameter of the fan assembly 1 is greater than or equal to the outer diameter of the power supply assembly 2, so that the overall size of the present invention is small, easy to carry and use. In particular, when it can be clipped to clothing and backpacks, it is not easy to fall off or tilt, making it extremely convenient to use.

[0041] The power supply assembly 2 includes a lower shell 21, an upper shell 22 fixed to the lower end of the lower shell 21, a main board 23 installed between the lower shell 21 and the upper shell 22, and a rechargeable battery 24 for power supply. The rechargeable battery 24 is electrically connected to the main board 23. The main board 23 is also electrically connected to the motor assembly 12 and the cooling chip 14 after passing through the first hole 221 at the upper end of the upper shell 22 and the second hole 110 at the lower end of the outer shell 11 with wires.

[0042] The inner wall of the lower shell 21 is formed with multiple support strips 211 and positioning protrusions 212 located beside the support strips 211. The lower end of the upper shell 22 is provided with multiple positioning buckles 222 that are adapted to the positioning protrusions 212. The upper shell 22 is externally embedded in the upper opening of the lower shell 21 and contacts the upper end of the support strips 211. The positioning buckles 222 are engaged with the positioning protrusions 212 to fix the upper shell 22 to the upper end of the lower shell 21. The structure is stable and easy to install. Furthermore, by externally embedding the upper shell 22 in the upper opening of the lower shell 21, the overall structure is smaller and more stable. The upper shell 22 is fixedly connected to the bottom of the outer shell 11 by a second screw, ensuring structural stability.

[0043] The clip assembly 3 includes a clip 31 and a support plate 32 rotatably mounted on the lower end of the clip 31 and openable outward relative to the clip 31. The lower end of the clip 31 has a storage groove 311. The support plate 32 is folded and stored in the storage groove 311 relative to the lower end of the clip 31. When the support function is not needed, the support plate 32 is folded and stored in the storage groove 311. When the support function is required, the support plate 32 opens outward relative to the clip 31. The lower end surfaces of the support plate 32 and the protruding portion of the clip 31 are flush, forming two support lines to stably support and position the device on a desktop for use as a table fan.

[0044] The upper end of the clip 31 is rotatably connected to the lower shell 21 of the power supply component 2, so that the direction of the air outlet can be better adjusted to meet different usage requirements.

[0045] The clamp 31 has a convex ring 312 and a circular threaded post 313 located at the center of the convex ring 312 at its upper end; the lower shell 21 of the power supply assembly 2 has a circular groove 213 and a shaft hole 214 penetrating the bottom at its bottom. The convex ring 312 passes through the circular groove 213 from bottom to top, and the circular threaded post 313 passes through the shaft hole 214 from bottom to top to form a rotatable structure. A third screw (not shown in the figure) is screwed down and fixed in the threaded groove 314 of the circular threaded post 313 to limit the circular threaded post 313 and the convex ring 312 in the circular groove 213 and the shaft hole 214 respectively, thereby forming a stable rotating structure.

[0046] The circular threaded post 313 is fitted with a wear-resistant plate 315 to increase the damping force. The upper end of the wear-resistant plate 315 contacts the bottom surface of the circular groove 213, thereby enhancing the damping force. This makes it necessary for the clamp 31 and the power supply component 2 to generate mutual rotation, and also allows the clamp 31 and the lower shell 21 of the power supply component 2 to be positioned after rotation, making it more convenient to use.

[0047] In summary, this utility model provides a metal sheet 15 protruding from the surface of the outer shell 11 and a cooling plate 14 attached to the metal sheet 15. When the cooling plate 14 is working, it cools and transfers the cold to the metal sheet 15, making the overall temperature of the metal sheet 15 lower. It can be used to contact human skin to achieve the function of ice pack, which can be better favored by consumers in the hot summer and meet the usage requirements of different consumers.

[0048] Of course, the above description is only a specific embodiment of the present utility model and is not intended to limit the scope of the present utility model.
