It should be noted that, referring to fig. 2, the fan assembly 1 may be disposed on one side of the display screen, or may be disposed on two sides of the display screen, in this embodiment, the fan assembly 1 is disposed on two sides, so that on one hand, convection air flow blown out from the two fan assemblies 1 may be generated, and on the other hand, turbulence is formed at the collision place to bring dust adsorbed on the display screen under the turbulence, so as to achieve a certain cleaning effect; on the other hand, the support on both sides of the dust removing assembly 2 can be provided, so that the dust removing assembly 2 is more stable.
Referring to fig. 3, a shunt tube 114 extending along an up-down direction is further disposed in the air guiding tube 11, the shunt tube 114 is disposed in a cylindrical shape, a third air outlet 1141 extending along the up-down direction is provided at one side of the shunt tube 114, and the shunt tube 114 may rotate along an axis thereof, so that the third air outlet 1141 is communicated with the first air outlet 111 or the third air outlet 1141 is communicated with the second air outlet 112. The consideration of the power of the ion fan assembly 131 is combined with the consideration of the static removing position required in the use process of the display screen, and the shunt pipe 114 is arranged to shunt the airflow with ions, so that the air outlet capacity of the ion fan assembly 131 only needs to meet the air outlet of one air outlet, the power of the ion fan assembly 131 is reduced, the noise is reduced, and meanwhile, a good static removing effect is achieved. When the display screen is electrified and started, the third air outlet 1141 is communicated with the second air outlet 112, so that a large amount of static electricity generated on the back surface of the display screen at the position of the power supply connection flat cable is removed, and dust in the outside air is prevented from being sucked from the radiating holes; after a certain period of time, as the display surface of the display screen is exposed to the air, dust is easily adsorbed on the back surface, that is, the shunt tube 114 is rotated to enable the third air outlet 1141 to be communicated with the first air outlet 111, and the display surface of the display screen is continuously covered by the airflow with ions so as to keep the display surface from accumulating static electricity to adsorb the dust in the air in the use process of the display screen; when the display screen is powered off, the shunt tube 114 delays rotating for a certain time, so that after static electricity on the display screen display surface is completely removed, the third air outlet 1141 is communicated with the second air outlet 112 again, static electricity accumulated on the back of the display screen is removed, no static electricity accumulation on the display screen is generated after the power-off of the display screen is completed, and dust is prevented from being adsorbed by the display screen to keep clean.
Referring to fig. 3, the shunt tube 114 extends downward beyond the air guiding tube 11, and a portion of the bottom of the shunt tube 114 extending beyond the air guiding tube 11 is provided with a rotation matching portion 1142, a side edge of the air guiding tube 11 is fixedly provided with a first driving assembly 12, the first driving assembly 12 includes a rotation driving portion 121, and the rotation driving portion 121 is matched with the rotation matching portion 1142 to drive the shunt tube 114 to rotate along an axis thereof. The rotation of the shunt tube 114 may be manually completed or automatically completed by a setting device, and the device may be set to be a combination of a driving motor and a gear and then be matched with the gear, or a combination of a telescopic device and a rack and then be matched with the gear, in this embodiment, the rotation of the shunt tube 114 is completed by driving the first driving component 12, and the combination of the driving motor and the gear is selected by the first driving component 12, the rotation driving part 121 is set to be a driving gear 121a, and the rotation matching part 1142 is set to be matched with the gear 1142a, so that the use is convenient, and the rotation time and the rotation positioning are more accurate.
Referring to fig. 4, a plurality of partitions 1143 are disposed in the shunt tube 114 at intervals, the partitions 1143 are configured to divide the shunt tube 114 into a plurality of chambers 1144, air inlet ends of the chambers 1144 are disposed at the bottom of the shunt tube 114, air outlet ends of the chambers 1144 are arranged along a length direction of the shunt tube 114 to form the third air outlet 1141, and cross-sectional areas of the air outlet ends of the chambers 1144 are gradually reduced along a direction away from the air inlet ends of the chambers 1144 to balance the air flow at each position of the third air outlet 1141. The ion fan assembly 131 is disposed at the lower end of the air guide pipe 11, so that the air inlet of the ion fan assembly is disposed at the bottom of the fan assembly 1, and dust falling in air can be prevented from being sucked, but the airflow speed of a single fan is gradually reduced in the shunt pipe 114 by using the single fan, so that the air speed is smaller at a position far from the ion fan assembly 131, and the airflow blown out of the third air outlet 1141 is uneven. In order to solve the problem of uneven airflow, the splitter 114 is divided into different chambers 1144 by using a plurality of baffles 1143, so that the cross-sectional area of the air inlet end of each chamber 1144 is ensured to be the same, that is, the air inlet volume is the same, the further the air outlet end of each chamber 1144 is from the ion blower assembly 131, the more the air speed is attenuated, but the cross-sectional area of the air outlet end of each chamber 1144 is synchronously reduced, and the air inlet volumes in the chambers 1144 are consistent, the smaller cross-sectional area of the air outlet end enables the extrusion of air to improve the air speed of the air outlet end of each chamber 1144, so as to reduce or even eliminate the attenuation of the air speed, and ensure the balance and stability of the air flow at each position of the third air outlet 1141.
Referring to fig. 3, the ion fan assembly 131 includes an ionization assembly 131 and an axial fan 132, the ionization assembly 131 is disposed at the lower end of the air guide pipe 11, and includes a plurality of discharge needles 1311 disposed inside a cylindrical housing 1312, the discharge needles 1311 extend from the cylindrical housing 1312 toward the center of the housing 1312, so that the discharge needles 1311 are accommodated between the housings 1312, and the occupied volume is reduced to reduce the occupied volume of the ion fan assembly 131; the axial flow fan 132 is disposed below the ionization component 131, and the axial flow fan 132 can provide a larger air volume to meet the air volume requirement of the fan component 1.
Referring to fig. 5, the upper frame 211 and the lower frame 212 are provided with corresponding guiding grooves 213 extending in a horizontal direction, one end of the cleaning assembly 22 is movably connected with the guiding grooves 213 on the upper frame 211, and the other end of the cleaning assembly 22 is movably connected with the guiding grooves 213 on the lower frame 212, so as to keep the cleaning assembly 22 in a vertical state, and prevent the cleaning assembly 22 from tilting to generate cleaning dead angles, so that the back of the display screen cannot be completely cleaned.
Referring to fig. 5, the guide groove 213 is disposed at a rearward incline near an end of the air duct 11, so as to separate the cleaning assembly 22 from the back of the display screen when the cleaning assembly 22 moves to approach the air duct 11. On the one hand, the wind power near the air guide pipe 11 is high, and the cleaning component 22 is separated from the back of the display screen when approaching the air guide pipe 11 so as to avoid the air flow, and avoid the fault or damage of the cleaning component 22; on the other hand, the cleaning component 22 can prevent static electricity in the middle of the back of the display screen from being eliminated after blocking the air flow, and the cleaning component 22 is separated from the back of the display screen when approaching to the air guide pipe 11 so as to avoid the air flow, thereby ensuring the static electricity removing effect. The wind power near the wind guide pipe 11 is large, dust is difficult to adhere, and the cleaning component 22 is not needed for cleaning.
