[0025] The outbreak of the virus shows that large, crowded public places have long ignored disinfection and epidemic prevention. On the other hand, it also reveals that there is no economically feasible technology and equipment for regular, comprehensive disinfection and epidemic prevention in large public places. For public places, regular disinfection and ventilation are essential epidemic prevention measures.

[0026] To solve the above problems, the present invention proposes an ultra-large multifunctional spray disinfection and epidemic prevention ceiling fan, please refer to Figure 1-Figure 3 , is a specific embodiment of the super-large multifunctional spray disinfection and epidemic prevention ceiling fan of the present invention, the super-large multifunctional spray disinfection and epidemic prevention ceiling fan comprises a liquid medicine diluter 1, an atomizer 2, a rotary distributor 5, a driving device, a fan blade 6 and a control box 3, the input end of the atomizer 2 is connected to the liquid medicine diluter 1, the output end of the atomizer 2 is connected to the input end of the rotary distributor 5, the fan blade 6 is provided with a spray pipe, the output end of the rotary distributor 5 is connected to the spray pipe, and an atomizing nozzle 61 is provided on the spray pipe for atomizing the high-pressure disinfectant through the spray pipe and then spraying it out, the control box 3 is electrically connected to the motor 4 and the atomizer 2; wherein, the motor 4 has a drive shaft 43 fixedly connected to the fan blade 6, and the rotary distributor is mounted on the drive shaft 43 to rotate with the drive shaft 43.

[0027] After the disinfectant is pressurized by the atomizer, it is transported to the rotary distributor 5, and then transported by the rotary distributor 5 to the spray pipe on the fan blade 6, and finally atomized and sprayed out continuously through the atomizing nozzle 61.

[0028] The function of the rotary distributor 5 is to distribute the liquid medicine into the spray pipe on the fan blade when the fan blade 6 rotates.

[0029] It is understandable that the driving device in this embodiment includes a motor 41 and a reduction box 42, the control box 3 is electrically connected to the motor 41, and the reduction box 42 is connected to the fan blade 6 through the drive shaft 43 to drive it to rotate. The driving device can also be any other device that can provide power for rotational motion, all of which belong to the protection scope of the present invention. The atomizing nozzle belongs to the conventional technical means of the prior art in this field, so its specific structure does not need to be repeated.

[0030] Preferably, the fan blade 6 is hollow, and has the spray pipe built in it. A plurality of atomizing nozzle seats are arranged at intervals on the spray pipe. A plurality of outer wall holes corresponding to the positions of the atomizing nozzle seats are arranged at intervals on the outer wall of each fan blade 6, and each atomizing nozzle 61 is installed on each atomizing nozzle seat. Such a design is a comprehensive consideration of the system being sufficiently pressure-resistant, the mist particles being easy to diffuse, the air resistance being small enough, the atomizing nozzle 61 being difficult to clog, and the fan blade having a beautiful appearance.

[0031] See also Figure 1 In this embodiment, the liquid medicine diluter 1 is used to automatically mix the disinfectant raw material and tap water to form a disinfectant that meets the standard, thereby improving work efficiency. Specifically, in this embodiment, the liquid medicine diluter 1 is connected to the input end of the atomizer 2 through the first pipeline 71, the output end of the atomizer 2 is connected to the input end of the liquid medicine dispensing device through the second pipeline 72, and the output end of the liquid medicine dispensing device is connected to the spray pipeline through the third pipeline 73. After the atomizer 2 raises the disinfectant to a certain pressure, it is transported to the liquid medicine dispensing device 5 through the second pipeline 72, and then transported to each third pipeline 73 by the liquid medicine dispensing device 5, so that the atomized disinfectant enters the spray pipeline through the third pipeline 73, and finally sprays out continuously from the spray pipeline. The liquid medicine dispensing device 5 of this embodiment can rotate with the drive shaft 43, and when the ceiling fan is working, it can maintain a continuous supply and output of the atomized disinfectant.

[0032] Furthermore, the rotation diameter of the fan blade 6 of the present invention is 5-8 meters, and the disinfection working area can reach 800 square meters.

[0033] Furthermore, the size of the mist particles sprayed by the atomizing nozzle 61 is 0.1-10 μm, which is close to the particle size of bacteria and viruses, and can easily absorb viruses and bacteria, thereby achieving a good disinfection effect. In this embodiment, a plurality of atomizing nozzles 61 are provided on the fan blade 6 .

[0034] For further information, see Figure 1 and Figure 2The rotary distributor 5 includes a moving coil 51 and a stationary coil 52. The moving coil 51 is sleeved and fixed on the outer circumference of the driving shaft 43. A plurality of internal flow channels 511 are provided on the moving coil 51. Two ends of each internal flow channel 511 are respectively provided with a liquid medicine inlet 512 and a liquid medicine outlet 513. Each liquid medicine outlet 513 is connected to the spray pipe; the stationary coil 52 is sleeved on the outer circumference of the moving coil 51 and fixed to the driving device. An annular flow channel 521 connected to each liquid medicine inlet 512 is provided in the stationary coil 52. A stationary coil liquid inlet 522 is provided on the outer circumference of the stationary coil 52. Two ends of the stationary coil liquid inlet 522 are respectively connected to the atomizer 2 and the liquid medicine inlet 512 of the annular flow channel 521.

[0035] In this embodiment, the structure is simple, the design is ingenious and the processing is convenient. Through the cooperation of the dynamic ring 51 and the static ring 52, a rotary seal is formed, so that the atomized disinfectant can continuously enter the liquid medicine cavity of each blade 6 during the rotation of the blade 6. In this embodiment, the liquid medicine dispensing device 5 also includes a rotating bearing 53 sleeved on the outer wall of the dynamic ring 51, and the inner wall of the inner ring wall is provided with a second groove corresponding to the rotating bearing 53 to reduce the friction between the dynamic ring 51 and the static ring 52.

[0036] By connecting each of the liquid medicine outlets 513 to the spray pipe, it is effectively and reasonably achieved that the high-pressure liquid medicine is delivered to the spray pipe of each fan blade 6 for the next atomization operation.

[0037] Further, if Figure 2 As shown, the internal flow channel 511 is a hole-shaped flow channel extending in the up-down direction, and the liquid medicine inlet is arranged above the liquid medicine outlet.

[0038] Furthermore, the rotary distributor 5 also includes a sealing ring 54 sleeved on the outer wall of the moving coil 51, and a first groove is provided on the inner wall of the moving coil 51 corresponding to the sealing ring 54 to ensure the sealing between the moving coil 51 and the stationary coil 52 to prevent leakage of the atomized disinfectant.

[0039] Furthermore, the rotary distributor 5 further comprises a rotary bearing 53 sleeved on the outer wall of the moving ring 51 , and a second groove is provided on the inner wall of the stationary ring 52 corresponding to the rotary bearing 53 to ensure the rotation coaxiality between the moving ring 51 and the stationary ring 52 .

[0040] In this embodiment, through the cooperation of the dynamic coil 51 and the static coil 52, the disinfectant can be continuously supplied to each spray pipe during the rotation of the fan blade 6.

[0041] It is understandable that if Figure 2As shown, the processing technology of each of the hole-shaped flow channels can be: first drill a vertical hole along the end face of the moving coil 51 (i.e., the position of the process plug 11) along the axial direction, and then drill two transverse holes along the radial direction on the outer peripheral surface of the moving coil 51, one of which is used to communicate with the third pipeline 73, and the other is used to communicate with the annular flow channel 521, and finally plug the process plug 11 at the vertical hole. Of course, the moving coil 51 can also be processed in many sections and then welded to form each of the hole-shaped flow channels. Each of the hole-shaped flow channels can also adopt any other processing technology.

[0042] The lower surface of the driving device frame bottom plate is provided with a stop pin 9 for limiting the rotation of the stationary ring 52. The driving shaft 43 is provided with a transmission key 8 for fixing the moving ring 51, and the fan chassis assembly 10 is installed on one end of the driving shaft 43 through a fastener 12.

[0043] The working principle of the present invention is as follows: first, according to the dilution ratio of the disinfectant, the automatic diluter 1 is adjusted and connected to tap water and disinfectant, the atomizer 2 is started through the control box 3, the diluted liquid is pressurized by the atomizer 2, and then distributed to each spray pipe through the rotary distributor 5, and finally atomized and sprayed out through the atomizing nozzle 61.

[0044] It should be noted that the present invention is designed to use 84 disinfectant. The disinfection principle is: the active ingredient NaClO in the 84 disinfectant is hydrolyzed to generate HClO (hypochlorous acid). Although HClO is weakly acidic, it has strong oxidizing properties and can easily denature proteins. It can quickly destroy the protein shell of the virus and kill the virus.

[0045] When the disinfection function is activated, the numerous atomizing nozzles 61 distributed on the fan blades will spray out the disinfectant in atomized form. As the fan blades rotate (10 to 20 revolutions per minute), these continuously sprayed liquid mist particles will be evenly dispersed into the flowing air by the wind. Since the particle size of viruses and bacteria is relatively close to that of the liquid medicine, they are easily adsorbed and the adsorbed viruses and bacteria are killed.

[0046] The design installation height of the present invention is generally above 4.5m. Under normal weather conditions, the fog particles can gradually evaporate after settling for about 2 meters, and intermittent disinfection can be carried out even when there are people.

[0047] The present invention has multiple uses in one machine. When only the ventilation function is used (the sprayer is turned off), it can create a soothing three-dimensional natural wind, which fully meets the ventilation requirements of the National Health Commission for public places. When the cooling function is used, only water is used (no liquid medicine is supplied), and the fan blade speed is 40 to 60 rpm. At this time, the present invention applies the principle of water evaporation refrigeration, and the temperature reduction range can reach 4-10°C (there will be fluctuations due to the influence of relative humidity). If it assists the central air-conditioning in cooling, the energy-saving effect is significant, and electricity saving can reach more than 30%. By setting the operating parameters, the present invention can also achieve functions such as moisturizing, dust reduction, and static electricity elimination.

[0048] The effective coverage area of ​​a single unit of the present invention can reach 800 square meters, and the power consumption is only 2 kilowatts.

[0049] The present invention has low energy consumption, high efficiency, multiple functions and stepless speed regulation, and is an ideal equipment for disinfection and epidemic prevention in large public places.

[0050] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
