[0002] Circulation fans, also called air circulation fans, can make the wind blow out in a spiral shape along a certain direction compared to traditional electric fans. As the fan blades stir, a spiral columnar wind can be formed. Generally, the wind blown out by a circulation fan has a longer distance and better directionality. Such wind has a larger contact surface with the surrounding air, which breaks up the surrounding air, drives more air to participate in the indoor air circulation, accelerates the indoor air circulation, and thus balances the indoor temperature. The wind can be blown out in a spiral shape along a certain direction. As the fan blades stir, a spiral columnar wind can be formed. The wind blown out by an air circulation fan has a longer distance and better directionality.

[0025] Furthermore, in a preferred embodiment of a circulation fan of the utility model, a connecting portion 30 is provided in the middle of the double fork arm 3 for fixed installation on the top of the main control portion 2, and a wire management groove 33 is provided in the double fork arm 3, and the wire management groove 3 is used for placing power supply lines to supply power and signal transmission to the fan assembly 6 and the swing motor 5.
[0026] Furthermore, in a preferred embodiment of a circulation fan of the utility model, a wire hole 24 is provided on the back of the main control unit 2, and the wire hole 24 is used for external wires to enter the interior to provide electrical energy.
[0027] Furthermore, in a preferred embodiment of a circulation fan of the utility model, the central processor signal is connected to and controls the operation of the water pump, the fan assembly 6 and the swing motor 5; the ranging probe 23 and the humidity sensor 21 are signal-connected to the central processor.
[0028] Furthermore, in a preferred embodiment of a circulation fan of the utility model, the supporting mechanism includes a base 1, a column 12 is vertically arranged on the base 1, a sleeve 13 is movably arranged outside the column 12, the sleeve 13 is provided with bolts, the ends of the bolts are pressed against the outer surface of the column 12, and the sleeve 13 is placed down under the action of friction; the water tank 11 is arranged on the base 1.
[0029] The device is provided with a water tank 11, which can provide clean water, so that the water mist sprayed by the spray head 22 will not affect human health. The spray head is arranged on the front of the main control part 2 below the head 4, and the spray head 22 sprays water mist obliquely upward in the direction of the air blowing of the head 4. The water mist flows rapidly under the drive of the air flow, so that it can spread and diffuse rapidly in the area, thereby increasing the humidity in the entire area.
[0030] Because the northwest region is relatively dry, tourists traveling from the southeast will feel very uncomfortable. Existing spray humidifiers can increase humidity, but they are located in a fixed position to work, and the humidified air needs to spread throughout the space to produce an effect. When the circulating fan of this device is working, it will automatically transport the humidified air, thereby increasing the speed.
[0031] The humidity sensor 21 of the device is cleverly positioned below the machine head 4, so that it is not affected by the fan blades and the water mist of the spray head when working, and has a relatively high accuracy. In conjunction with the central processor, the operation of the spray head and the water pump can be adjusted according to the humidity in the area.
[0032] The wet air blows on the human body or some objects at close range, which may cause hidden dangers. Therefore, a distance measuring probe 23 in the same direction as the spray head 22 is provided at the front. When a human body or an object is detected at close range, the work of the spray head 22 is stopped.
[0033] The following is in conjunction with the instruction manual Figure 1 and attached Figure 3 , the structure of the device is described in detail: the device includes a supporting mechanism and a main control part 2 arranged thereon, the main control part 2 is provided with a rotating motor, and is driven by the motor to rotate on the supporting mechanism; a double fork arm 3 is provided on the top of the main control part 2, and a machine head 4 is swingably provided on the double fork arm 3, and a fan assembly 6 is provided in the machine head 4; a water pump is also provided in the main control part 2 and a spray head 22 is provided on the front; the supporting mechanism is provided with a water tank 11, and the water pump pipeline is connected to the water tank 11.
[0034] The function of the rotating motor is to drive the main control unit 2 to rotate on the supporting mechanism, thereby adjusting the wind direction.
[0035] The double fork arm 3 includes a first connection end 31 and a second connection end 32. A swing motor 5 is fixedly arranged inside the machine head 4. The end of the output shaft of the swing motor 5 is fixedly connected to the first connection end 31. A rotating sleeve 46 is arranged on the other side of the machine head 4. The second connection end 32 is provided with a rotating shaft. The rotating sleeve 46 is sleeved on the rotating shaft. The rotating shaft and the output shaft of the swing motor 5 are in the same line. When the swing motor 5 rotates, the entire machine head 4 can be driven to rotate with the straight line where the rotating shaft and the output shaft of the swing motor 5 are located as the central axis. By changing the rotation direction of the swing motor 5, the up and down swing of the machine head 4 is realized.
[0036] The head 4 includes a fan blade cylinder, and a front mesh cover 41 and a rear mesh cover 42 are provided at both ends of the fan blade cylinder. A center plate 43 is provided in the middle of the rear mesh cover 42, and a motor compartment 44 is provided on the center plate 43. The motor compartment 44 is provided with the fan assembly 6; a line pipe 45 is provided between the motor compartment 44 and the rotating sleeve 46.
[0037] A connection part 30 is provided in the middle of the double fork arm 3. The connection part 30 is fixedly mounted on the top of the main control part 2 by a snap. In addition, a plurality of holes are provided on the top for use by the humidity sensor 21, which can detect the humidity in the air. This position is located below the fan blade cylinder, so it will not be affected by the blown air, and the correct humidity in the surrounding area can be accurately detected.
[0038] A wire management slot 33 is provided inside the double fork arm 3, which is used to conceal the power supply line and the signal line. From the outside, except for an external power line for drawing power, no wire can be seen in the rest of the device, so the overall appearance is relatively neat and looks relatively high-end.
[0039] The device is provided with a wire hole 24 on the back of the main control part 2, and the wire hole 24 is used for external wires to enter the interior to provide power. A central processor is provided in the main control part 2; a distance probe 23 is also provided on the front of the main control part 2 and a humidity sensor 21 is provided on the top. The central processor signal connects and controls the operation of the water pump, the fan assembly 6 and the swing motor 5; the distance probe 23 and the humidity sensor 21 signal connect the central processor.
[0040] The supporting mechanism includes a base 1. A column 12 is vertically arranged on the base 1. A sleeve 13 is movably arranged outside the column 12. The sleeve 13 is provided with a bolt. The end of the bolt presses against the outer surface of the column 12, and the sleeve 13 is placed down under the action of friction. The water tank 11 is arranged on the base 1.
[0041] The water tank 11 is connected with a water supply pipe, which enters the sleeve 13 from the column 12, and then enters the main control part 2 upward to be connected with the water pump.
[0042] In summary, the circulation fan of the utility model is provided with a spray device, which is suitable for dry areas in summer. The water mist flows rapidly under the drive of the air flow, so that it can spread and diffuse rapidly in the area, thereby increasing the humidity in the entire area. The volatilized water vapor is dispersed into the air by circulating wind, which avoids the air drying caused by the loss of water in the air caused by the use of an air circulation fan alone; the combined flow of wind and water mist can accelerate the reduction of indoor temperature. One machine with multiple uses not only saves consumers' purchase costs, but also reduces energy consumption and increases consumers' experience value.
