An intermediate connecting pipe 113 is fixedly installed at the top end of the support air suction shell 116, a rotating assembly is arranged on the intermediate connecting pipe 113, the rotating assembly comprises a planetary gear ring support 123 rotatably installed at the top end of the inner wall of the intermediate connecting pipe 113 and a gear ring 109, and the planetary gear ring support 123 and the gear ring 109 are rotatably connected. The gear ring 109 is coaxially and fixedly connected with the second magnetic installation ring 108, the second magnetic installation ring 108 is rotatably connected with the top end of the intermediate connecting pipe 113, a ring-shaped electromagnet 112 is fixedly sleeved on the outer surface of the intermediate connecting pipe 113 at the position of the planetary gear ring support 123, and the ring-shaped electromagnet 112 is magnetically connected with the planetary gear ring support 123.

The support air suction shell 116 and the intermediate connecting pipe 113 are fixedly connected through a supercharging turbine fan support 117; a supercharging chamber 125 is fixedly installed at the top of the inner wall of the support air suction shell 116, a supercharging turbine fan 119 is rotatably arranged in the supercharging chamber 125, the supercharging turbine fan 119 is rotatably installed on the supercharging turbine fan support 117, and a flow guide cover 118 is further fixedly installed on the side of the supercharging turbine fan support 117 away from the supercharging turbine fan 119. A driving motor 124 is fixedly installed at the bottom of the inner wall of the support air suction shell 116, and driving motor cooling fins 126 are fixedly installed on the outer surface of the driving motor 124; a transmission shaft 122 is fixedly installed on the output shaft of the driving motor 124, and the middle gear 121 and the supercharging turbine fan 119 are fixedly connected with the transmission shaft 122. The transmission shaft 122 is rotatably connected with the flow guide cover 118 and the supercharging turbine fan support 117.

[0024] The working principle of the multifunctional all-around air circulation fan is as follows: the first magnetic mounting ring 103 and the second magnetic mounting ring 108 can be separated conveniently, so that the annular flow guide shell 101 and the support air suction shell 116 can be separated, facilitating carrying and storage. When in use, the first magnetic mounting ring 103 and the second magnetic mounting ring 108 are connected together, and the first mounting permanent magnet block 110 and the second mounting permanent magnet block 111 are aligned and then magnetically attracted together, so as to connect the first magnetic mounting ring 103 and the second magnetic mounting ring 108. The driving motor 124 is started, the output shaft of the driving motor 124 drives the transmission shaft 122 to rotate, the middle gear 121 and the booster turbine fan 119 fixed with the transmission shaft 122 rotate, the booster turbine fan 119 rotates to suck air into the inside of the booster chamber 125, and then rotates with the booster turbine fan 119, the sucked air flows along the radial direction of the booster turbine fan 119 under the centrifugal force, and then flows into the middle connecting pipe 113 through the gap between the flow guide cover 118 and the middle connecting pipe 113, and then flows into the installation pipe seat 102 and then flows into the annular flow guide shell 101. In this process, the external air passes through the filter screen 114, enters the support air suction shell 116 after being filtered by the filter screen 114, and is then sucked by the booster turbine fan 119. The air in the annular flow guide shell 101 is sprayed out through the annular nozzle 104, the speed of the sprayed air is increased due to the effect of the annular nozzle 104 (the annular nozzle 104 is used to reduce the cross-sectional area of air flow to increase the flow rate), and then drives the air flow. In this process, the air sprayed from the annular nozzle 104 drives the surrounding air to flow together, the air at the axial position of the annular flow guide shell 101 is driven by the air sprayed from the annular nozzle 104, so that more air is driven, thereby improving the flow of the air (the position pressure of the air sprayed from the annular nozzle 104 is low, so the air at other positions around the air column flows to the annular nozzle 104).

[0025] If the direction of the air flow jetted from the annular nozzle 104 is to be changed, the annular electromagnet 112 is activated to generate a magnetic force to attract the planetary gear annular support 123. The planetary gear annular support 123 is restricted from rotating when it is attracted by the magnetic force of the annular electromagnet 112. Therefore, the revolution of the planetary gear 120 mounted on the planetary gear annular support 123 is restricted. At this time, the rotation of the intermediate gear 121 drives the gear ring 109 to rotate through the revolution-restricted planetary gear 120. The rotation of the gear ring 109 drives the second magnetic attraction mounting ring 108 to rotate, and the rotation of the second magnetic attraction mounting ring 108 drives the first magnetic attraction mounting ring 103, the mounting pipe base 102, and the annular flow guide shell 101 to rotate, thereby changing the direction of the jetted air flow. The direction of the jetted air flow can be rotated in all directions. By changing the magnetic force generated by the annular electromagnet 112, the magnetic force received by the planetary gear annular support 123 can be changed, and the restriction force received by the revolution of the planetary gear 120 can be changed. When the restriction force received by the revolution of the planetary gear 120 increases, the rotation speed ratio transmitted from the intermediate gear 121 to the gear ring 109 increases, thereby adjusting the transmission ratio between the intermediate gear 121 and the gear ring 109. Therefore, the rotation speed of the gear ring 109 can be controlled by controlling the magnetic force of the annular electromagnet 112, and the rotation speed of the annular flow guide shell 101 jetting the air flow can be controlled.

[0026] The first discharge ring 106 and the second discharge ring 107 are connected to the output end of the high-voltage generator. High voltage is applied between the first discharge ring 106 and the second discharge ring 107 (high voltage and low current), so that an electric arc is formed between the first discharge ring 106 and the second discharge ring 107. The electric arc breaks through the air to generate ozone. The ozone is carried away by the flowing air, moves with the flowing air, and then flows in the room to purify the air in the room (ozone can decompose organic pollutants, kill bacteria, viruses, and fungi, and remove odors such as smoke and mold). It should be noted that this function needs to be used when there is no one in the room, and the ozone concentration needs to be controlled within the safety threshold of 0.1 ppm. In addition, it needs to be used in cooperation with the fresh air system in the room, and the ozone needs to be discharged to the outdoor after use.
