Description

Automatic cleaning system and method of ion waterfall air purifier with external water tank

Technical Field

The present disclosure relates to air purifiers, and more particularly, to an automatic cleaning system and method for an ion waterfall air purifier with an external water tank.

Background

The ion waterfall purifier is a technology for purifying air by using an ion waterfall technology. Pollutants in the air are formed into a strong ion field by billions of positive or negative ions released in the ion waterfall chamber and are instantly pushed to a collecting wall of the ion waterfall chamber, and the pollutants collected by the collecting wall are cleaned by cleaning water without stopping and timing.

The existing flushing device is a cleaning tube with a nozzle. On the one hand, the existing flushing device is used for one-way water spraying, and cannot cover the area of the whole ion waterfall purification module, so that incomplete cleaning is caused. Alternatively, the contaminant may be anything in the air, such as particulate matter, bacteria, viruses, and the like, which are pathogenic microorganisms. The most important sources of pollutants are aerosols of sand, coal, particles of various sizes, bacteria and viruses, and come from industrial, vehicle, indoor production sources and the like.

Fig. 11 is a schematic partially exploded view of the rotating assembly of the flushing device of fig. 6.

As shown in fig. 6, and also in fig. 7-11, the present embodiment provides a flushing device 9 for spraying a cleaning medium for cleaning of contaminants. The flushing device 9 may generally comprise: two cleaning tubes 910, a rotating assembly 920, and a plurality of nozzles 930. The two cleaning tubes 910 are identical in size and are arranged in a straight line. The opposite ends of the two cleaning pipes 910 are fixedly connected together through a rotating assembly 920, the other ends of the two cleaning pipes 910 are plugged through corresponding plugs 911, and the two cleaning pipes 910 are used for flowing cleaning media. A plurality of branch openings are formed in each cleaning pipe 910 at the pipe wall opposite to the rotating assembly 920, and are used as a mounting base of the nozzle 930. The rotating assembly 920 is used to connect to the opposite ends of the two cleaning tubes 910, and is configured to drive the two cleaning tubes 910 to rotate along the center of the rotating assembly 920. A plurality of nozzles 930 are adapted to be correspondingly installed at the plurality of branch ports. In this embodiment, the number of the nozzles 930 is 6, and the nozzles are divided into two groups of three corresponding to the left cleaning pipe 910 and the right cleaning pipe 910. Of course, the number of nozzles 930 may be 4, 8, 10, etc. or any other even number, as desired. A first included angle α is formed between the center line of each nozzle 930 and the normal of the corresponding mounting surface. The nozzles 930 at each cleaning pipe 910 are installed in the same direction, that is, the three nozzles 930 at the left cleaning pipe 910 are installed in the same direction, and the three nozzles 930 at the right cleaning pipe 910 are installed in the same direction. The nozzles 930 at the two cleaning pipes 910 are installed in different directions. As shown in fig. 9, in the present embodiment, the three nozzles 30 at the left cleaning pipe 910 are inclined downward with respect to the normal line, and the three nozzles 930 at the right cleaning pipe 910 are inclined upward with respect to the normal line. As shown in fig. 10, a second included angle β is formed between the center lines of the nozzles 930 at the two cleaning pipes 910. The angle of the second angle beta is twice the angle of the first angle alpha (see fig. 6). As shown in fig. 9, when the plurality of nozzles 930 spray the cleaning medium, the cleaning medium sprayed by the plurality of nozzles 930 forms a torsional moment with respect to the center of the rotating assembly 920, so that the rotating assembly 920 rotates, thereby driving the flushing device 9 to rotate at 360 °.

More specifically, in the present embodiment, as shown in fig. 11, the rotating assembly 920 includes: a hub 921, a first bearing 922, a hub fastener 923, a second bearing 924, and a coupling nut 925. The hub 921 is a three-way structure having two straight ends 9211 and a vertical end 9212. The two straight-through ends 9211 correspond to the two cleaning tubes 910, and are used for inserting and fixedly connecting the corresponding cleaning tubes 910, so that the two cleaning tubes 910 perform 360-degree rotation movement along with the hub 921. The first bearing 922 and the hub fixing member 923 are vertically stacked above the vertical end 9212 of the hub 921. The first bearing 922 is used to isolate the movement between the hub 921 and the hub fixture 923. The first bearing 922 serves as a lubrication surface and a sliding member. The hub fixing piece 923 is of a tubular structure and is used for connecting an external pipeline for conveying a cleaning medium so as to connect the hub 921 and the external pipeline together and serve as a sliding piece. The second bearing 924 is configured to be sleeved on the outer surface of the hub fixing member 923, so as to isolate the movement between the hub 921 and the hub fixing member 923. The second bearing 924 serves as a lubrication surface and a sliding member. The connecting nut 925 is used for sleeving the outer surfaces of the second bearing 924 and the vertical end 9212 of the hub 921 and is fixedly connected with the vertical end 9212 of the hub 921, so that the second bearing 924, the hub fixing piece 923, the first bearing 922 and the hub 921 are connected together and form an axial sliding surface.

In this embodiment, the purpose of the flushing device 9 is to clean the pollutants collected on the ion waterfall cleaning module 70. The contaminants may be anything in the air such as particulate matter, bacteria, viruses, and other pathogenic microorganisms. The most important sources of pollutants are aerosols of sand, coal, particles of various sizes, bacteria and viruses, and come from industrial, vehicle, indoor production sources and the like. The contaminants attached to the ion cascade purification module 70 may be difficult to remove, so that a strong detergent is required to remove, and the material of the washing device 9 must also be resistant to a highly corrosive detergent. Therefore, in this embodiment, the first bearing 922 and the second bearing 924 are preferably made of teflon. Of course, the first bearing 922 and the second bearing 924 may be made of other corrosion-resistant materials.

As shown in fig. 9, the cleaning medium enters the cleaning pipe 910 through the hub 921 and is sprayed out by six nozzles 930, the three nozzles 930 on the left side are sprayed downward, the three water sprays on the right side are sprayed upward, so that a clockwise torque is formed, and the hub 921 is driven to rotate, so that the cleaning pipe 910 is driven to rotate. At this time, the lower race of the first bearing 922 rotates in contact with the hub 921 and the upper race of the first bearing 922 is stationary by the first bearing 922. The coupling nut 925 rotates with the hub 921. Under the action of the second bearing 924, the outer race of the second bearing 924 rotates with the coupling nut 925, and the inner race of the second bearing 924 is stationary, so that the hub fixing 923 is stationary.

In addition, since the cleaning tube 910 is made of a plastic tube, which is light in weight and causes less tension to the hub 921, the hub 921 is constructed so that it can be assembled with each other using teflon or other friction-based materials. After assembly, the cleaning medium, i.e. tap water or water containing a cleaning liquid or a drier, can be used for lubrication of the rotating sliding surface when supplied to the interior of the flushing device 9. The water pressure presses the rotating sliding surfaces against each other, reducing the amount of water leakage and maintaining a minimum pressure of 2 bar in the lines of the flushing device 9.

More specifically, in the present embodiment, each nozzle 930 is a 120 ° fan nozzle.
