[0040] First Embodiment

[0041] Please see Figures 1 to 6 The first embodiment of this application provides a fan 10, which can be a portable fan. The fan 10 includes a fan housing 21 and a fan blade assembly 22. The fan housing 21 has a storage cavity 21a, an air inlet 21b communicating with the storage cavity 21a, and an air outlet 2420 communicating with the storage cavity. The fan blade assembly 22 is located in the storage cavity 21a and includes a blade assembly 221 and a motor assembly 222a. The motor assembly 222a includes a motor 222 connected to the blade assembly 221, a circuit board 222b connected to the motor 222, and at least one light-emitting element 222c. The motor 222 is used to drive the blade assembly 221 to rotate so as to guide the air from the air inlet 21b to the air outlet 2420. The at least one light-emitting element 222c is disposed on the circuit board 222b and is used to emit light toward the air inlet 21b and / or the air outlet 2420.

[0042] In this embodiment, the fan 10 is a handheld misting fan capable of both blowing air and spraying mist. Therefore, the fan 10 may further include an atomizing element 31 and a water tank 32. The water tank 32 can be disposed around the fan housing 21, and the atomizing element 31 can be disposed at the water outlet 320 of the water tank 32, used to atomize the water at the water outlet 320 into a mist, which is then sprayed out through the mist outlet 2410 of the fan housing 21. The mist outlet 2410 can be located in the middle of a plurality of air outlets 2420. With this arrangement, the airflow from the plurality of air outlets 2420 can be arranged approximately evenly around the mist outlet 2410, thereby improving the blowing and spraying effect of the fan 10.

[0043] In this embodiment, the motor 222 is disposed on the circuit board 222b, and the at least one light-emitting element 222c is also disposed on the circuit board 222b, emitting light towards the air inlet 21b and / or the air outlet 2420. The spray fan 10 and the motor assembly 222a have a light-emitting effect, providing a better user experience and enhancing the product's competitiveness. The motor 222 can be soldered to the first surface of the circuit board 222b, and the at least one light-emitting element 222c can also be soldered to the first surface of the circuit board 222b. However, in other embodiments, the at least one light-emitting element 222c can also be disposed (e.g., soldered) on a second surface of the circuit board 222b opposite to the first surface, thus allowing the at least one light-emitting element 222c and the motor 222 to be disposed on different sides of the circuit board 222b. Alternatively, in some other embodiments, the at least one light-emitting element 222c may include multiple light-emitting elements. Some of the light-emitting elements 222c may be located on the same side surface of the circuit board 222b as the motor 222, while other light-emitting elements 222c may be located on different side surfaces of the circuit board 222b as the motor 222. That is, the multiple light-emitting elements 222c may also be distributed on both sides of the circuit board 222b, so that both sides of the motor assembly 222a can emit light, thereby achieving a better light-emitting effect.

[0044] Specifically, the blade assembly 221 includes a mounting portion 221a and a plurality of blades 221b arranged around the mounting portion 221a. The mounting portion 221a is used to mount the motor 222, and the circuit board 222b is connected to one side of the motor 222. The at least one light-emitting element 222c includes a plurality of light-emitting elements 222c arranged around the circuit board 222b. It can be understood that multiple light-emitting elements 222c can achieve better lighting or luminous atmosphere effects, resulting in a higher user experience.

[0045] In this embodiment, the mounting portion 221a has a mounting cavity 221c, the motor 222 is located in the mounting cavity 221c, the at least one light-emitting element 222c and the motor 222 are disposed on the same side of the circuit board 222b, and a plurality of light-emitting elements 222c are arranged around the periphery of the motor 222. Further, the spray fan 10 also includes a plurality of electronic components 222d, which can be resistors, capacitors and / or chips, disposed on the circuit board 222b and located on the opposite side of the motor 222. It can be understood that the above design makes the layout of the circuit board 222b reasonable, the manufacturing process simple and the cost low, and also helps to avoid electrical interference.

[0046] In this embodiment, the at least one light-emitting element 222c includes a light source component (such as an LED light source with RGB three-color sub-light sources) capable of emitting multiple different colors of light. The light source component includes at least two sub-light sources of different colors, each individually controlled and switched on / off. Each sub-light source emits one color of light, thereby enabling the light source component to emit multiple different colors of light. The number of the at least one light-emitting element 222c is multiple, and each light-emitting element includes a light source component capable of emitting multiple different colors of light. It can be understood that the light source component allows the fan to be controlled to emit different light effects, such as different colors of light, continuously switching colors, and / or flashing marquee lights, enabling the fan to provide a higher level of ambiance and a better user experience.

[0047] It can be understood that the fan blade assembly 22 is an axial flow fan blade assembly, and the air inlet 21b, the receiving cavity 21a and the air outlet 2420 are arranged on the same straight line; the fan 10 may also include a control component 41a (such as a main circuit board 41, buttons 421 and 422, etc.), the control component 41a is electrically connected to the circuit board 222b, and is used to control the operation of the motor 222b and the illumination of at least one light-emitting element 222c.

[0048] The fan blade assembly 22 is an axial flow fan blade assembly. The air inlet 21b, the receiving cavity 21a, and the air outlet 2420 are arranged in the same straight line, which not only makes the spray fan 10 have high wind efficiency, but also makes the light effect observable from both the air inlet 21b and the air outlet 2420, resulting in better light emission effect of the spray fan 10.

[0049] Please see Figure 7-13 The equivalent circuit of the spray fan 10 may include a charging management circuit 61, a fan drive circuit 62, a main control circuit 63, an indicator light circuit 64, a battery protection circuit 65, a light-emitting drive circuit 66, and an atomization drive circuit 67. The light-emitting drive circuit 66 may be mounted on the circuit board 222b, while the charging management circuit 61, fan drive circuit 62, main control circuit 63, indicator light circuit 64, battery protection circuit 65, and atomization drive circuit 67 may be mounted on the main circuit board 41. The atomization drive circuit 67 includes a boost circuit 671, which receives the voltage BAT+ of the battery 424 and boosts the voltage BAT+ to output a drive voltage to the atomizing element 31, thereby driving the atomizing element 31 to operate. The drive voltage is greater than the battery voltage. Specifically, the voltage BAT+ of the battery 424 may be 5V, and the drive voltage may be approximately 80V, or it may be set according to actual needs.

[0050] The boost circuit 671 includes an inductor T1, a capacitor C18, and a control switch Q4. The first end of the inductor T1 is connected to the positive terminal (e.g., BAT+) of the battery 424. The second end of the inductor T1 is grounded through the two conducting terminals of the control switch Q4. The third end of the inductor T1 is connected to the positive terminal of the atomizing element 31 through the capacitor C18. The negative terminal of the atomizing element 31 is connected to the second end of the inductor T1. The control terminal of the control switch Q4 is connected to the main control circuit 63.
