The present invention does not make specific requirements on the specific structure and preparation process of the water purification component 1, and it can be set according to actual needs in specific implementations.

[0046] The wastewater treatment component 2 includes a wastewater collector 21, and a wastewater filter 211 and a cleaning component 212 provided on the wastewater collector 21; the wastewater collector 21 is provided with a wastewater inlet and a filtered wastewater outlet 210, the wastewater inlet is communicated with the wastewater outlet 11, and is used to receive the wastewater discharged through the wastewater outlet 11; the wastewater filter 211 is used to filter the wastewater in the wastewater collector 21 to obtain filtered wastewater; the filtered wastewater outlet 210 is communicated with a preset water use point and is used to output the filtered wastewater.

[0047] Specifically, the size of the wastewater collector 21 can be set according to actual needs. The wastewater filter 211 can be a filter mesh plate or other filters; the number of the filtered wastewater outlets 210 can be determined according to actual needs, and can be one or multiple.

[0048] A controller, which is electrically connected to the cleaning component 212, is used to send a cleaning instruction to the cleaning component 212 so that the cleaning component 212 cleans the wastewater filter 211 in response to the cleaning instruction.

[0049] Specifically, the controller can send a cleaning instruction to the cleaning component 212 based on a preset time interval; the controller can also respond to the relevant signal received from the mobile terminal indicating the cleaning wastewater filter 211, and then send a cleaning instruction to the cleaning component 212; the controller can also be electrically connected to the control panel. Among them, the water purification device is configured with a control panel, and the controller can respond to the relevant signal received from the control panel indicating the cleaning wastewater filter 211, and then send a cleaning instruction to the cleaning component 212. The controller can start timing while sending the cleaning instruction. After the timing duration reaches a certain length, a signal is sent to the control panel to remind the user to send the relevant signal indicating the cleaning wastewater filter 211 through the control panel again. The present invention does not specifically limit the implementation manner of the controller sending the cleaning instruction to the cleaning component 212, and can be set according to actual needs in specific implementation.

[0050] In an exemplary embodiment, the wastewater filter 211 is disposed in the wastewater collector 21 at a first preset angle and is located between the wastewater inlet and the filtered wastewater outlet 210, dividing the inner cavity of the wastewater collector 21 into a first chamber 213 and a second chamber 214.

[0051] Specifically, the first preset angle can be set according to actual needs, and the spatial size or shape of the first chamber 213 and the second chamber 214 can be set according to actual needs.

[0052] Among them, the first chamber 213 is communicated with the wastewater inlet and is used for receiving the wastewater input through the wastewater inlet; the second chamber 214 is communicated with the filtered wastewater outlet 210 and is used for collecting the filtered wastewater obtained by filtering and treating the wastewater through the wastewater filter 211, and outputting the collected filtered wastewater through the filtered wastewater outlet 210. Specifically, the number of the filtered wastewater outlets 210 and the specific position of the filtered wastewater outlet 210 in the second chamber 214 can be set according to actual needs.

[0053] Exemplarily, please refer to Figure 3, the wastewater filter element 211 is horizontally arranged in the wastewater collector 21 and is located between the wastewater inlet and the filtered wastewater outlet 210. The inner cavity of the wastewater collector 21 is divided into a first chamber 213 and a second chamber 214 from bottom to top. Among them, the volume of the second chamber 214 is much larger than that of the first chamber 213. The first chamber 213 is communicated with the wastewater inlet and is used to receive the wastewater input through the wastewater inlet. The second chamber 214 is communicated with the filtered wastewater outlet 210 and is used to collect the filtered wastewater obtained by filtering and treating the wastewater through the wastewater filter element 211, and output the collected filtered wastewater through the filtered wastewater outlet 210. By horizontally arranging the wastewater filter element 211 in the wastewater collector 21 and dividing the inner cavity of the wastewater collector 21 into a first chamber 213 and a second chamber 214 from bottom to top, while filtering the wastewater, it can also realize the natural sedimentation of the filtered wastewater to accumulate directionally on the wastewater filter element 211 for convenient subsequent cleaning. By setting the volume of the second chamber 214 to be much larger than that of the first chamber 213, it not only ensures the filtration efficiency, avoids frequent drainage, but also provides sufficient storage space for the filtered wastewater.

[0054] In an exemplary embodiment, the cleaning assembly 212 includes:

[0055] A backwashing mechanism 2121, which is arranged in the second chamber 214 and is communicated with the water inlet pipeline 3 outside the water purification device, is used to receive the cleaning water flow input through the water inlet pipeline 3, and direct the received cleaning water flow to the wastewater filter element 211 at a preset spraying angle.

[0056] Specifically, the quantity, size, shape and specific setting position of the backwashing mechanism 2121 can be set according to actual needs in specific implementations. The preset spraying angle can be adapted to the filtering structure of the wastewater filter element 211 and can be set according to actual needs in specific implementations. Exemplarily, please refer to Figure 3 , the cleaning assembly 212 includes: a backwashing mechanism 2121, which is arranged in the second chamber 214 and is communicated with the water inlet pipeline 3 outside the water purification device, is used to receive the cleaning water flow input through the water inlet pipeline 3. By directing the received cleaning water flow vertically downward and perpendicular to the wastewater filter element 211 to the wastewater filter element 211, the backwashing effect is improved.

[0057] In an exemplary embodiment, the backwashing mechanism 2121 includes:

[0058] A housing 2123, in which a third chamber 2124 is provided; the housing 2123 is provided with a cleaning water flow inlet 2125 and a water spraying port 2126 that are communicated with the third chamber 2124.

[0059] Specifically, the shape and size of the housing are set according to actual needs. The number of the water spray nozzles 2126 can be one or more, which can be set according to actual needs in specific implementation. The shape of the water spray nozzles 2126 can be set according to actual needs in specific implementation.

[0060] The clean water inlet 2125 is connected to the water inlet pipeline 3 and is used to receive the clean water flow input through the water inlet pipeline 3. A corresponding solenoid valve 21250 is provided on the clean water inlet 2125 and is electrically connected to the controller, which is used to receive and respond to the cleaning instruction, open the clean water inlet 2125, and close the clean water inlet 2125 after completing the tasks set by the cleaning instruction.

[0061] Specifically, the tasks set by the cleaning instruction may include the cleaning time, the flow rate of the clean water flow, or other cleaning-related setting parameters. The specific content of the tasks set by the cleaning instruction is set according to actual needs in specific implementation. The specific position of the corresponding solenoid valve 21250 provided on the clean water inlet 2125 is set according to actual needs. It can be set at the clean water inlet 2125, or at the connecting part between the clean water inlet 2125 and the water inlet pipeline 3, or on the water inlet pipeline 3, as long as it can control the water inlet condition of the clean water inlet 2125.

[0062] The third chamber 2124 is used to divert the clean water flow received through the clean water inlet 2125 to the water spray nozzles 2126. The central axis of the water spray nozzles 2126 is set on the housing 2123 at a second preset angle, and the water outlet direction of the water spray nozzles 2126 faces the wastewater filter element 211, so that the water spray nozzles 2126 direct the clean water flow diverted through the third chamber 2124 to the wastewater filter element 211 at a preset spraying angle.

[0063] Specifically, the size or shape of the third chamber 2124 is set according to actual needs in specific implementation.

[0064] Exemplarily, please refer to Figure 2 and 3, the recoil mechanism 2121 includes: a housing 2123 provided with a third chamber 2124 therein; the housing 2123 is provided with a cleaning water inlet 2125 and a plurality of water spray nozzles 2126 communicating with the third chamber 2124. The aperture of the water spray nozzle 2126 gradually decreases along the water outlet direction, and the housing 2123 and the cover plate 6 of the wastewater collector 21 are of an integral configuration. By setting the cover plate 6 and the housing 2123 as an integral configuration and arranging it on the top of the wastewater collector 21, it is used to seal the wastewater collector 21, saving the preparation cost, facilitating the cleaning of the wastewater filter element 211, and while avoiding external pollution, ensuring that the wastewater collector 21 does not leak liquid during the working state (especially during the process of the recoil mechanism 2121 cleaning the wastewater filter element 211), thus avoiding polluting the external environment. The cover plate 6 can also be made of a transparent material (such as transparent glass), and the internal state of the wastewater collector 21, such as the accumulation of impurities, damage to the wastewater filter element 211, or the deviation of the fixed position of the wastewater filter element 211, can be directly observed.

[0065] In an exemplary embodiment, the wastewater collector 21 is further provided with a cleaning water drain 2127 communicating with the first chamber 213 for discharging the cleaning water ejected from the water spray nozzle 2126.

[0066] In a specific implementation, the size of the cleaning water drain 2127 can be set according to actual needs.

[0067] A corresponding solenoid valve 21270 is provided on the cleaning water drain 2127 and is electrically connected to the controller; the controller is further configured to control the on-off state of the cleaning water drain 2127 by opening or closing the solenoid valve 21270 corresponding to the cleaning water drain 2127.

[0068] In a specific implementation, a drain valve 21271 can also be provided at the cleaning water drain 2127. In the embodiments of the present application, the specific position of the corresponding solenoid valve 21270 provided on the cleaning water drain 2127 is not specifically limited, as long as it can control the on-off state of the corresponding cleaning water drain 2127. The cleaning water drain 2127 can be opened before the cleaning assembly 212 cleans the wastewater filter element 211, can be opened during the process of the cleaning assembly 212 cleaning the wastewater filter element 211, or can be opened after the cleaning assembly 212 cleans the wastewater filter element 211, which can be set according to specific circumstances.

[0069] Exemplarily, please refer to Figure 3 and 4, the wastewater collector 21 is also provided with a clean water drainage port 2127, which communicates with the first chamber 213 and is used to discharge the clean water sprayed out through the water spray port 2126; a corresponding solenoid valve 21270 (preferably a one-way solenoid valve) is provided on the clean water drainage port 2127 and is electrically connected to the controller; the controller is used to control the on-off state of the clean water drainage port 2127 by opening or closing the solenoid valve 21270 corresponding to the clean water drainage port 2127. By providing the clean water drainage port 2127 whose on-off state can be controlled by the controller, the automatic discharge of the clean wastewater after the clean wastewater filter element 211 from the wastewater collector 21 is realized.

[0070] In an exemplary embodiment, the cleaning assembly 212 further includes:

[0071] The ultrasonic oscillator 2122 is electrically connected to the controller and is used to receive and respond to the cleaning instruction and clean the wastewater filter element 211 according to the target working parameters.

[0072] Specifically, the model and quantity of the ultrasonic oscillator 2122 can be set according to actual needs, and the target working parameters can include vibration frequency, working duration, etc.

[0073] Exemplarily, please refer to Figure 4 , three such ultrasonic oscillators 2122 are arranged at the bottom of the wastewater collector 21, and the three ultrasonic oscillators 2122 are distributed at three different positions at the bottom of the wastewater collector 21. By arranging the three ultrasonic oscillators 2122 in a triangular distribution, it is ensured that the entire bottom area of the wastewater collector 21 is covered, avoiding dead corners where cleaning is not in place.

[0074] In an exemplary embodiment, the wastewater collector 21 is provided with a plurality of filtered wastewater outlets 210; the plurality of filtered wastewater outlets 210 are in one-to-one correspondence and communication with a plurality of preset water use points; corresponding solenoid valves are respectively provided on the plurality of filtered wastewater outlets 210 and are electrically connected to the controller; a first water quality sensor is provided in the second chamber 214 and is electrically connected to the controller and is used to perform a first detection on the filtered wastewater and send the first detection result obtained from the first detection to the controller; the first detection result indicates the impurity content in the filtered wastewater; the controller is further used to selectively control the on-off states of the plurality of filtered wastewater outlets 210 respectively according to the comparison result between the first detection result and the first preset threshold by opening or closing the solenoid valves corresponding to the plurality of filtered wastewater outlets 210.

[0075] Specifically, the preset water usage points may be one or more of the water usage points of a washbasin, a toilet flushing water usage point, a flower watering water usage point, or other water usage points. The water quality detector can be used to detect one or more combinations of suspended particulate matter, heavy metal ions, or other impurities in the filtered wastewater, and the quantity and detection type of the water quality detector can be set according to actual needs.

[0076] Exemplarily, the wastewater collector 21 is provided with a plurality of filtered wastewater outlets 210 that are respectively and correspondingly communicated with a plurality of preset water usage points; corresponding electromagnetic valves are respectively arranged on the plurality of filtered wastewater outlets 210 and are electrically connected to the controller; a first water quality sensor is arranged in the second chamber 214 and is electrically connected to the controller for performing a first detection on the filtered wastewater and sending the first detection result obtained from the first detection to the controller; the first detection result indicates the impurity content in the filtered wastewater; by setting the controller to selectively control the on-off states of the plurality of filtered wastewater outlets 210 respectively according to the comparison result between the first detection result and a first preset threshold value by opening or closing the electromagnetic valves corresponding to the plurality of filtered wastewater outlets 210, the use of the filtered wastewater can be reasonably allocated according to the actual water quality of the filtered wastewater.

[0077] In an exemplary embodiment, the water purification device further includes a display device; the controller is further configured to, when the first detection result is less than a second preset threshold value, prompt the user to perform maintenance on the water purification device through the display device.

[0078] Specifically, the setting of the second preset threshold value can refer to the impurity content in the tap water purified by the water purification component 1 to be purified. Exemplarily, the water purification device further includes a display device; the controller is further configured to, when the first detection result is less than a second preset threshold value, prompt the user to perform maintenance on the water purification device through the display device. In addition, the embodiments of the present application consider that in the prior art, the replacement of the filter element in the water purification component 1 is usually based on the installation duration or the purified water volume of the filter element in the water purification component 1. Therefore, on the basis of reasonably allocating the filtered wastewater according to the comparison result between the first detection result detected by the first water quality sensor and the first preset threshold value, the first detection result can also be used to detect whether the water purification device is in a normal state. When the first detection result is less than a second preset threshold value, the user is prompted to perform maintenance on the water purification device through the display device, and the cost is saved. In another exemplary embodiment, the controller is further configured to, when the first detection result is greater than a third preset threshold value, prompt the user to perform maintenance on the wastewater filter element 211 through the display device, including checking whether the wastewater filter element 211 is damaged or whether the fixed position of the wastewater filter element 211 in the wastewater collector 21 has shifted.
