[0040] Please refer to the attached Figure 1 -Attached Figure 4An embodiment of the utility model provides a fan device, including a first shell 10, a second shell 20, a scissor-type linkage assembly 30 and a driving device 40. One of the first shell 10 and the second shell 20 is provided with an air outlet 50. The scissor-type linkage assembly 30 is arranged between the first shell 10 and the second shell 20. For example, the two ends of the scissor-type linkage assembly 30 are respectively connected to the first shell 10 and the second shell 20; the driving device 40 is connected to the scissor-type linkage assembly 30, and the driving device 40 is used to drive the scissor arms in the scissor-type linkage assembly 30 to open and close. The opening and closing movement of the scissor arms can make the scissor-type linkage assembly 30 telescopically move, driving the first shell 10 and the second shell 20 to move relatively away from or close to each other, so that the position and size of the air outlet 50 can be adjusted.

[0041] Among them, the second shell 20 is a top opening structure, the first shell 10 is a bottom opening structure, and the opening of the second shell 20 is arranged opposite to the opening of the first shell 10. Further, the first shell 10 can be an inner shell, and the second shell 20 can be an outer shell. The first shell 10 is nested in the second shell 20, so that the first shell 10 and the second shell 20 are enclosed together to form a receiving cavity, and the scissor-type connecting rod assembly 30 is arranged in the receiving cavity. In some specific examples, the outer periphery of the first shell 10 is provided with an air outlet 50, and the second shell 20 is provided with an air inlet 60. The opening and closing movement of the scissor arms causes the scissor-type connecting rod assembly 30 to telescopically move in a direction perpendicular to the bottom surface of the second shell 20, driving the first shell 10 to move away from or close to the second shell 20, so as to reduce or increase the size of the air outlet 50 and adjust the position of the air outlet 50. The first shell 10 is close to the second shell 20 so that the first shell 10 can be stored in the second shell 20. It can be explained that the scissor-type linkage assembly 30 can drive the first housing 10 to move closer to or farther from the second housing 20 to form a storage state in which the first housing 10 is stored in the second housing 20 and a working state in which the first housing 10 extends to the second housing 20, such as Figure 1 As shown, in the storage state, the air outlet 50 is hidden in the second housing 20, which prevents the user from seeing the internal structure of the fan device through the air outlet 50, making the product beautiful, and can also reduce the size of the entire fan device, saving space and facilitating storage. Figure 2 As shown, in the working state, the first shell 10 extends out of the second shell 20, so that the air outlet 50 can be partially or fully exposed, thereby achieving the purpose of adjusting the size and position of the air outlet 50.

[0042] In this embodiment, the scissor-type linkage assembly 30 is arranged between the first housing 10 and the second housing 20. The opening and closing movement of the scissor arms of the scissor-type linkage assembly 30 can make the scissor-type linkage assembly 30 telescopically movable, so as to adjust the relative movement of the first housing 10 and the second housing 20 of the fan device, thereby adjusting the size and position of the air outlet 50 of the fan device, so that the user can flexibly adjust the size and position of the air outlet 50 according to different needs. In addition, when the fan device is not used, the scissor-type linkage assembly 30 can adjust the first housing 10 and the second housing 20 to be relatively close to achieve a storage effect, which can reduce the size of the entire fan device, save space, and facilitate storage.

[0043] It should be further explained that the fan device can be a heater, such as a skirting heater. The skirting heater is a heating device installed at the skirting (bottom of the wall), and its design is inspired by the shape of the skirting. The skirting heater is in the shape of a long strip, similar to the shape of the skirting. Further, a fan 100 and a heating component 110 are arranged in the accommodation cavity formed by the first shell 10 and the second shell 20. The airflow sucked from the air inlet 60 by the rotation of the fan 100 is heated by the heating component 110 to form warm air, and the warm air is blown out from the air outlet 50. In addition, the fan device can also be a cold air fan. In this case, a fan 100 and a refrigeration component are arranged in the accommodation cavity formed by the first shell 10 and the second shell 20. The airflow sucked from the air inlet 60 by the rotation of the fan 100 is cooled by the refrigeration component to form cold air, and the cold air is blown out from the air outlet 50.

[0044] In some optional embodiments, the fan 100 is disposed in an area inside the second shell 20 close to the bottom surface of the second shell 20, and the air inlet 60 is disposed corresponding to the fan 100, and can be disposed on the bottom surface of the second shell 20 or on the side wall of the second shell 20, and the air outlet 50 can be disposed on the side wall of the first shell 10.

[0045] Please refer to the attached Figure 5 -Attached Figure 8In some optional embodiments, the scissor-type connecting rod assembly 30 includes a connecting rod body 31 and a follower 32 formed by a scissor arm; one end of the connecting rod body 31 is connected to the second shell 20, and the other end is connected to the follower 32, and the end of the follower 32 away from the connecting rod body 31 is connected to the first shell 10. The setting of the follower 32 can reduce the stroke of the opening and closing movement of the connecting rod body 31, thereby reducing the space occupied by the connecting rod body 31 in the fan device; the connecting rod body 31 is connected to the driving device 40, and the driving device 40 drives the scissor arm in the connecting rod body 31 to open and close, so that the follower 32 drives the first shell 10 to telescopic movement relative to the second shell 20. A connecting piece 321 is provided at one end of the follower 32 away from the connecting rod body 31. The follower 32 is connected to the first shell 10 via the connecting piece 321. The surface area of ​​the connecting piece 321 is larger than the cross-sectional area of ​​the follower 32. The setting of the connecting piece 321 can make the driving force of the follower 32 be transmitted to the first shell 10 more evenly, so as to avoid the driving force being concentrated and causing the first shell 10 as a whole to be unable to smoothly extend and retract.

[0046] In some optional embodiments, the scissor arms of the scissor-type connecting rod assembly 30 include a starting scissor unit 311, an intermediate scissor unit 312, and a terminal scissor unit 313 connected in sequence; the driving device 40 is connected to the starting scissor unit 311. The follower 32 is connected to the terminal scissor unit 313. In some specific embodiments, the number of the intermediate scissor units 312 is multiple, and the multiple intermediate scissor units 312 are connected end to end. It should be further explained that each group of scissor units includes two connecting rods that can open and close relative to each other.

[0047] In some optional embodiments, the starting scissors-type unit 311 includes a driving sub-rod 3111 and a linkage sub-rod 3112; the output shaft 41 of the driving device 40 is fixedly connected to the driving sub-rod 3111, and the output shaft 41 of the driving device 40 is movably connected to the linkage sub-rod 3112. The output shaft 41 rotates to drive the driving sub-rod 3111 to rotate, so that a relative opening and closing movement is generated between the driving sub-rod 3111 and the linkage sub-rod 3112.

[0048] In some optional embodiments, the driving device 40 is a driving motor; the driving sub-rod 3111 is fixedly connected to the output shaft of the driving motor, and the linkage sub-rod 3112 is movably connected to the output shaft of the driving motor. The driving motor converts electrical energy into mechanical energy to drive the driving sub-rod 3111 to move. The driving motor can be a DC motor, an AC motor, a stepping motor or a servo motor. The relative opening and closing movement between the driving sub-rod 3111 and the linkage sub-rod 3112 is achieved by controlling the forward and reverse rotation of the driving motor.

[0049] In some optional embodiments, the linkage sub-rod 3112 is movably connected to the output shaft 41 through a bearing 314; it can be explained that the bearing 314 is usually composed of an inner ring and an outer ring and a rolling element sandwiched therebetween, the inner ring of the bearing 314 is sleeved on the output shaft 41, the linkage sub-rod 3112 is provided with a receiving hole, and the outer ring of the bearing 314 is installed in the receiving hole, so as to ensure smooth and reliable relative movement between the linkage sub-rod 3112 and the output shaft 41, and reduce the friction between the linkage sub-rod 3112 and the output shaft 41. In some optional embodiments, a washer 315 is provided between the driving sub-rod 3111 and the linkage sub-rod 3112 to prevent the driving sub-rod 3111 from directly contacting the linkage sub-rod 3112, thereby reducing the friction. The washer 315 is usually made of metal, plastic, rubber or other synthetic materials. In application, the washer 315 is precisely placed between the driving sub-rod 3111 and the linkage sub-rod 3112. In some other optional embodiments, a collar 316 is provided on the side of the linkage sub-rod 3112 away from the driving sub-rod 3111, and the movement of the linkage sub-rod 3112 can be limited by the setting of the collar 316. It can be explained that when the linkage sub-rod 3112 moves toward the collar 316, the collar 316 will block the linkage sub-rod 3112 from further movement, thus playing a role of limiting. In some other optional embodiments, a step portion is provided on the side of the driving sub-rod 3111 away from the linkage sub-rod 3112, and the movement of the driving sub-rod 3111 can be limited by the setting of the step portion. It can be explained that when the driving sub-rod 3111 moves toward the driving device 40, the step portion will block the driving sub-rod 3111 from further movement, thus playing a role of limiting.

[0050] Please see attached Fig. 9 In some optional embodiments, the number of the scissor-type link assemblies 30 is two groups, and the two groups of scissor-type link assemblies 30 are arranged at opposite ends of the second housing 20, and can perform opening and closing movements synchronously. Specifically, the two groups of scissor-type link assemblies 30 are respectively arranged at opposite ends in the length direction of the fan device, so that the telescopic movement of the first housing 10 relative to the second housing 20 is more stable.

[0051] In some optional embodiments, the two sets of scissor-type connecting rod assemblies 30 are connected by a connecting shaft 70; the output shaft 41 of the driving device 40 is connected to the connecting shaft 70 by a coupling 80. The coupling 80 is provided to ensure the connection stability between the driving device 40 and the connecting shaft 70.

[0052] In some optional embodiments, there are multiple intermediate scissor units 312; each intermediate scissor unit 312 includes a first connecting rod 3121 and a second connecting rod 3122 of the same size as the first connecting rod 3121, a hinge point 3123 is provided at the center point of the first connecting rod 3121, and the first connecting rod 3121 and the second connecting rod 3122 are movably connected through the hinge point 3123. The hinge point 3123 allows relative movement between the first connecting rod 3121 and the second connecting rod 3122, so that the intermediate scissor unit 312 opens and closes. A washer 315 is provided at the connection between the first connecting rod 3121 and the driving sub-rod 3111, and a washer 315 is provided at the connection between the second connecting rod 3122 and the linkage sub-rod 3112.

[0053] In some optional embodiments, a guide assembly 90 is further provided between the first shell 10 and the second shell 20, and the guide assembly 90 can guide the telescopic movement of the scissor-type linkage assembly 30, thereby ensuring that the scissor-type linkage assembly 30 remains stable during the telescopic movement.

[0054] It should be further explained that the guide assembly 90 includes a first support member 91 and a second support member 92 respectively connected to the first shell 10 and the second shell 20; one of the first support member 91 and the second support member 92 has a guide groove 921, and the other of the first support member 91 and the second support member 92 has a guide portion 911, and the guide portion 911 is located in the guide groove 921 and is slidably connected to the guide groove 921. In a specific example, the second support member 92 is provided with a guide groove 921, and the first support member 91 is provided with a guide portion 911, and the guide portion 911 is located in the guide groove 921. In this embodiment, the telescopic movement of the scissor-type connecting rod assembly 30 is guided by the sliding cooperation between the guide portion 911 and the guide groove 921, thereby improving the stability of the telescopic movement. Furthermore, travel switches, such as micro switches, can be provided at both ends of the guide groove 921. When the guide portion 911 contacts the travel switch, the travel switch will be triggered to cut off the power supply to the drive motor, thereby stopping the drive motor from working and realizing the timely hovering function, thereby avoiding excessive movement of the drive motor and causing damage to the scissor-type linkage assembly 30.
