[0002] With the development of the times and the increasing popularity of consumer goods, people have new demands on traditional fans, such as wind speed, availability during power outages, portability, and versatility. Currently, there are many types of desktop fans on the market, including small table fans with temperature control functions and small fans with mosquito coil boxes. Portable circulation fans have also kept pace with changes in people's needs, with multi-functions to meet different demand scenarios. The portability and availability during power outages have further expanded the application scenarios of the products. However, existing circulation fans have a single function and use, and their application scenarios are very limited. Some circulation fans cannot flexibly adjust and fix the fan's air outlet angle, which greatly affects the convenience of use and user experience of the circulation fans. Summary of the Invention

[0035] The working principle of the present utility model is further described below.

[0036] During the production process, first, according to the requirements of the product, the blowing assembly 200 and the connecting assembly 300 of corresponding shapes and specifications are selected, so that the blades 210 are fixed in the shield 220 through the motor 240; in this embodiment, the shield 220 is a front-to-back structure to facilitate the installation of the motor 240; then, the buttons 110, the temperature sensor 120, the display screen 130 and other components are fixedly installed in the base 100, and the speaker 322 is fixedly installed in the second bracket 320; then, the wires are led into the lead groove 221 on the shield 220, so that the lead wires of the motor 240 pass through the lead groove 221 and the lead hole 321 and are electrically connected to the buttons 110, the temperature sensor 120 and the display screen 130, etc. 21, install the baffle 222; then, install the lighting lamp 140 and the lampshade 223 on the shield 220; then, insert one end of the lead groove 221 into the lead hole 321 to flexibly connect the shield 220 with the second bracket 320, fix the gear 311 to the first bracket 310 through the positioning block 312, and insert the upper end of the first bracket 310 into the shield 220 through the gear 311 to engage with the thread 211; then, fix it in the positioning groove 225 through the mounting block 231, and install the storage bin 230 to the front end of the shield 220; finally, install the hook 150 in the slot 160 at the lower end of the base 100, and install the cover 330 on both sides of the shield 220, completing the assembly process of the circulation fan. The entire assembly process is efficient and controllable, which improves the production efficiency of the circulation fan.

[0037] During use, the circulation fan can be equipped with batteries or connected to an external power source. The user activates the circulation fan by pressing button 110, which causes the motor 240 to rotate the blades 210, and the circulation fan begins operating. During operation, the motor 240 adjusts its speed based on the reading from the temperature sensor 120 to change the speed of the blades 210, ensuring user comfort. Simultaneously, the user can rotate the blower assembly 200 using the handle 224 to rotate the gear 311. The engagement of the gear 311 with the thread 211 precisely secures the blades 210, changing the angle between the blades 210 and the base 100 and adjusting the airflow angle of the blades 210. Furthermore, the lighting 140 emits light to illuminate the circulation fan, suitable for dark environments like outdoors, enhancing its user convenience and user experience. Furthermore, the circulation fan receives user voice control commands via the sound receiving device 170, and the motor 240 adjusts its speed accordingly. Voice messages reflecting the current operating status are then sent to the user via the speaker 322, further enhancing the user experience of the circulation fan. The user can also remove the storage compartment 230 and install aromatherapy, mosquito coils, mosquito repellent oil, etc. in the storage compartment 230. When the blades 210 rotate, they can blow air towards the storage compartment 230 and transmit the aromatherapy, mosquito coils, etc. to the outside of the protective cover 220 through the through hole 232. In addition, the circulation fan can be hung upside down via the hook 150 as needed, improving the compatibility of the circulation fan.

[0038] At the same time, the user can use voice to trigger the speaker 322 to control the motor 240 to switch on and off, adjust the speed, and perform timing, turn the lighting 140 on and off, adjust the brightness of the lighting 140, and display the battery power on the display 130. When there is a voice command to wake up the circulation fan, the circulation fan responds to the corresponding action, and the display 130 displays the corresponding operation. The display 130 only displays for 5 seconds each time. If there is no new button or instruction action, it will go out. If there is further instruction, it will light up again. When the fan is turned off for 24 hours, if no voice command is received, the voice control system will be turned off. To wake up again, you need to press the button 110 and turn on the power.

[0039] In addition, the circulation fan collects the current temperature t through the temperature sensor 120 and controls the speed of the motor 240 to different gears according to the current temperature t. Specifically, when t≤18°C, the fan automatically shuts down and the motor 240 is in the off state; when t≤21°C, the fan automatically runs continuously at the first speed; when t≤21°C, the fan automatically runs continuously at the second speed; when t≤25°C, the fan automatically runs continuously at the third speed; when t≤29°C, the fan automatically runs continuously at the fourth speed; when t≥33°C, the fan automatically runs continuously at the fifth speed.

[0040] From the above description, it can be seen that the circulation fan of the present invention is provided with a blowing assembly 200 and a connecting assembly 300, and the blowing assembly 200 can be flexibly arranged on the base 100 to ensure the structural stability of the circulation fan; by providing a first bracket 310 and a second bracket 320, it is convenient to adjust the angle of the blade 210, and it is also convenient to lead the motor 240 to the base 100, thereby improving the convenience of use of the circulation fan; by providing a gear 311 and a thread 211, it is convenient to accurately adjust the angle between the shield 220 and the fixed base 100, thereby improving the convenience of use and user experience of the circulation fan; by providing a button 110, a temperature sensor 120 and a display screen 130 , ensuring that the motor 240 can control the opening according to the temperature sensor 120 and the button 110, and intuitively display the working status of the circulation fan through the display screen 130, thereby improving the convenience of using the circulation fan; by setting the lead hole 321, the convenience of wiring between the motor 240 and the button 110 and the temperature sensor 120 is guaranteed, and the cable is prevented from getting entangled during the rotation of the blowing component 200, affecting the structural stability of the circulation fan; by setting the positioning block 312, the gear 311 can be quickly and stably fixed in the first bracket 310, ensuring that the gear 311 can stably engage with the thread 211, thereby improving the positioning accuracy of the blowing component 200.
