[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] As Figure 1 shown, the present invention provides an air purifier component including a dust collecting plate 1, a cleaning mechanism, a flushing mechanism and a control system. The cleaning mechanism is used to clean the pollutants on the dust collecting plate 1, the flushing mechanism is used to flush water to the dust collecting plate 1, and the control system is used to control the operation of the cleaning mechanism and the flushing mechanism.

[0024] The cleaning mechanism includes a brush 2, a moving rod 3 and a driving mechanism. The brush 2 is installed on the moving rod 3. The driving mechanism is used to drive the moving rod 3 to move and rotate, and when the moving rod 3 moves and rotates, it can drive the brush 2 to clean the pollutants on the dust collecting plate 1.

[0025] The driving mechanism includes two sliding tracks 4, a linear motor (not shown in the figure) and a rotary motor (not shown in the figure). The two sliding tracks 4 can be respectively arranged on both sides of the dust collecting plate 1. The two ends of the moving rod 3 are respectively connected to the two sliding tracks 4. The linear motor is used to drive the moving rod 3 to reciprocate along the sliding track 4, and the rotary motor is used to drive the moving rod 3 to rotate around its axis, and the rotation angle can be 0 - 180°. For example, a slider can be respectively arranged on the two sliding tracks 4, the two ends of the moving rod 3 are respectively rotatably connected to the sliders, one end or both ends of the moving rod 3 are connected to the output shaft of the rotary motor, and the rotary motor can drive the moving rod 3 to rotate relative to the slider, and the slider can be pushed to reciprocate along the sliding track 4 by the linear motor. The brush 2 is installed on the moving rod 3. When the driving mechanism drives the moving rod 3 to move and rotate, the moving rod 3 drives the brush 2 to move and rotate, and the brush 2 can clean the pollutants on the dust collecting plate 1. In some other embodiments, the linear motor can also be replaced by a belt drive device. At this time, the slider is fixedly installed on the belt, and the rotary motor in the belt drive device drives the pulley to rotate, so as to drive the belt and the slider to reciprocate.

[0026] The flushing mechanism includes an inlet pipe (not shown in the figure), a shunt pipe (not shown in the figure), and a plurality of outlet pipes 5. An inlet valve (not shown in the figure) is provided on the inlet pipe. The inlet pipe is connected to the water inlet of the shunt pipe. The shunt pipe has a plurality of water outlets (not shown in the figure). Each water outlet is connected to an outlet pipe 5. An outlet valve (not shown in the figure) is provided on each outlet pipe 5. The outlet valve is used to adjust the water pressure of the outlet pipe 5. Water can be flushed onto the dust collecting plate 1 through the outlet pipe 5. The inlet pipe is externally connected to a water pump. Water is pumped to the shunt pipe through the water pump. The shunt pipe evenly distributes water to the outlet pipes 5. By adjusting the opening degree of the outlet valve, the cross-sectional area between the valve core and the valve seat is changed to control the water flow rate and pressure of the outlet pipe 5, thereby controlling the amount of water flushed and the water pressure on the dust collecting plate 1.

[0027] The driving mechanism drives the moving rod 3 and the brush 2 to rotate and reciprocate along the sliding guide rail to clean the dust collecting plate 1, and the flushing mechanism flushes water onto the dust collecting plate 1. Under the cooperation of cleaning and flushing, the dust collecting plate 1 is deeply cleaned.

[0028] The control system can control the operation of the cleaning mechanism and the flushing mechanism according to the cleaning effect achieved or the cleaning duration set by the user. When the cleaning reaches the required effect or the cleaning duration set by the user and enters the clean state, the air purifier will automatically stop the cleaning mode and dry the residual moisture through fresh air to ensure continuous use.

[0029] The control system includes an image acquisition unit and a control unit. The image acquisition unit is used to collect images of the dust collecting plate 1. The image acquisition unit includes a micro camera 6. The real-time image of the dust collecting plate 1 is collected through the micro camera 6 and uploaded to the control unit. The control unit includes a controller (not shown in the figure). A clean image of the dust collecting plate 1 when it is not in use is pre-stored in the controller. The controller uses the BP neural network algorithm to judge the cleaning effect of the dust collecting plate 1 based on the real-time image of the dust collecting plate 1 and the pre-stored clean image. If it is judged that the cleaning quality of the dust collecting plate 1 does not meet the standard, at this time, the controller can issue an instruction to the flushing mechanism to perform a flushing action, and cooperate with the brush 2 and the rotating shaft to drive the moving rod 3 to perform a cleaning action until the controller judges that the cleaning quality meets the standard, realizing self-cleaning.

[0030] The dust collecting plate 1 can be divided into multiple regions. The controller can respectively judge the cleaning quality of each region of the dust collecting plate 1 according to the image of the dust collecting plate 1, and flush the regions where the cleaning quality does not meet the standard. For example, in a preferred embodiment, 9 regions are divided on the dust collecting plate 1, and each region is flushed by a corresponding number of water outlet pipes 5. If it is judged that the cleaning quality of a certain region of the dust collecting plate 1 does not meet the standard, the controller can issue an instruction to the water outlet pipe 5 corresponding to this region, adjust the pressure and send water separately, and cooperate with the brush 2 and the rotating shaft to drive the moving rod 3 to perform the cleaning action until the controller judges that the cleaning quality of this region meets the standard, realizing fixed-point cleaning. Fixed-point cleaning avoids large-scale cleaning of the whole machine due to unqualified cleaning in a small range, can save water consumption, and clean accurately.

[0031] A water receiving tray with a certain inclination angle is installed below the dust collecting plate 1 (not shown in the figure). The water receiving tray is used to collect the sewage after cleaning and then discharge the sewage to the outside of the air purifier in time, avoiding the situation that the air purifier malfunctions due to too much accumulated sewage overflowing. When the water is lacking, water is pumped in and the cycle works again until the cleaning effect required by the user is achieved.

[0032] In one embodiment, the image acquisition unit further includes a micro camera (not shown in the figure) for collecting the internal image of the water receiving tray. The controller pre-stores an image of no water when the water receiving tray is not in use. The controller judges whether there is residual water in the water receiving tray according to the internal image of the water receiving tray collected by the micro camera and the pre-stored image of no water through the BP neural network algorithm. If there is residual water, continue to drain the water until all the residual water in the water receiving tray is drained.

[0033] When the cleaning quality meets the standard or the cleaning time reaches the cleaning duration set by the user, it enters the clean state. The air purifier will automatically stop the cleaning mode and dry the residual moisture through fresh air to ensure that the air purifier can continue to be used. In one embodiment, the air purifier assembly further includes a humidity sensor. The humidity of the dust collecting plate 1 is detected by the humidity sensor. When the humidity is below 95%, it is considered that the drainage meets the standard. If the drainage does not meet the standard, continue to drain the water until the drainage meets the standard.

[0034] The air purifier assembly provided by the present invention can be applied to an air purifier to realize the disassembly-free cleaning of the air purifier.

[0035] Figure 2 It is the cleaning flow chart of the air purifier. As Figure 2As shown, after starting the air purifier, the control system first determines whether cleaning is required. If cleaning is not required, the air purifier operates normally until the operation ends. If cleaning is required, the self-cleaning program is executed. When executing the self-cleaning program, the control system controls the speed of the brush 2 to clean the dust collecting plate 1 by controlling the rotational speeds of the linear motor and the rotary motor, and controls the water flow pressure of the water outlet pipe 5 to wash the dust collecting plate 1 by controlling the water outlet valve. After cleaning for a period of time, the control system captures the real-time image of the dust collecting plate 1 through the micro camera 6 and uploads the real-time image to the controller. The controller determines whether the cleaning quality of the dust collecting plate 1 meets the standard based on the real-time image of the dust collecting plate 1 and the pre-stored clean image. If the cleaning quality meets the standard, the sewage is discharged and the operation ends. If the cleaning quality does not meet the standard, the self-cleaning program can be executed cyclically by means of overall cleaning or spot cleaning until the cleaning quality meets the standard.

[0036] Although the present invention has been described with reference to the preferred embodiments, various modifications can be made to it and components therein can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
