[0053] In order to solve the problem that the existing air purification device can only sterilize the air flowing through the humidifying module, cannot sterilize the bacteria attached to the air flowing through the air path, and the air flowing out of the air outlet of the air conditioner still has bacteria attached, thereby affecting the sterilization effect of the air conditioner.

Figure 2 is a semi-sectional schematic view of the air purification module of the air purification device of an embodiment of the present application. Figure 3 is a flow chart of one embodiment of the control method of the air purification device of an embodiment of the present application. Figure 4 is a flow chart of another embodiment of the control method of the air purification device of an embodiment of the present application. Figure 5This is a flowchart of another embodiment of the control method of an air purification device according to an embodiment of the present invention. Figure 6 This is a flowchart illustrating another embodiment of the control method for an air purification device according to an embodiment of the present invention.

[0055] like Figure 1 As shown, see also Figure 2 The air purification device 100 includes an air conditioner body (not shown) and an air purification module 1. The air purification module 1 is installed inside the air conditioner body. Specifically, the air purification module 1 includes a receiving cavity 11, a water-spraying assembly 2, an air inlet 13, an air outlet 12, a sterilization assembly 3, and a fan (not shown). The receiving cavity 11 is located inside the air purification module 1 and is used to contain liquid water. The water-spraying assembly 2 is located inside the receiving cavity 11 and is configured to spray the liquid water inside the receiving cavity 11 towards the inner wall of the receiving cavity 11, so that the liquid water sprayed by the water-spraying assembly 2 can impact the inner wall of the receiving cavity 11 to form water mist. The air inlet 13 is located on the inner wall of the receiving cavity 11. The air outlet 12 is located on the top wall of the receiving cavity 11. The sterilization assembly 3 is located in the receiving cavity 11 and is configured to add a sterilizing agent to the liquid water. A fan is installed inside the air purification device 100 to adjust the air intake speed passing through the air inlet 13. Specifically, the fan is installed in the air duct (not shown) of the air conditioner body. Through this arrangement, the air purification device 100 of the present invention can add a disinfectant to liquid water via the sterilization component 3, and the water-spinning component 2 can throw the liquid water containing the disinfectant into the receiving cavity 11, so that the liquid water can impact the inner wall of the receiving cavity 11 to form a water mist containing the disinfectant. Thus, when air flows through the receiving cavity 11, the water mist containing the disinfectant in the receiving cavity 11 can effectively sterilize the air. Furthermore, during the air purification process of the air purification device 100, when the air flowing through the receiving cavity 11 is blown out from the air outlet 12, the disinfectant adhering to the air can sterilize the airflow path through which the air in the air purification module 1 flows, reducing the risk of bacteria adhering to the air and improving the sterilization effect of the air purification device 100.

[0056] Continue reading Figure 1 and Figure 2In a specific implementation of the present invention, the water-spinning assembly 2 includes a water-spinning component and a driving unit (not shown). The water-spinning component is disposed inside the receiving cavity 11. Specifically, the water-spinning component is rotatably connected to the bottom wall of the receiving cavity 11 via a rotating shaft. More specifically, the water-spinning component has a cavity inside. The cavity has a water inlet near the bottom of the receiving cavity 11, and a water outlet is provided at the end of the cavity away from the bottom of the receiving cavity 11. The position of the water inlet is configured such that when the water level of the liquid water inside the receiving cavity 11 is higher than a preset low threshold, the liquid water can block the water inlet. Thus, when the water-spinning component rotates, the liquid water inside the cavity can run towards the inner wall of the cavity under the action of centrifugal force. Finally, the liquid water is thrown out from the water outlet and thrown towards the inner wall of the receiving cavity 11 to form a water mist. The drive unit is located in the receiving cavity 11 and is used to drive the water-spinning component to rotate relative to the side wall of the receiving cavity 11. Specifically, the drive unit is a drive motor. The main body of the drive motor is fixedly connected to the bottom of the outer wall of the receiving cavity 11. The output shaft of the drive motor is connected to the rotating shaft so that the drive motor can drive the rotating shaft to rotate, thereby driving the water-spinning component to rotate.

[0057] Preferably, in the specific implementation of the present invention, in order to enable the liquid water to be quickly ejected from the outlet hole under the action of centrifugal force, the sidewall of the cavity is configured to gradually extend outward from the bottom of the receiving cavity 11 to the direction away from the bottom of the receiving cavity 11, so that the liquid water can move towards the outlet hole more quickly under the action of centrifugal force.

[0058] It should be noted that, although the above combination Figure 2 The described water-spinning component has an internal cavity with a water inlet at the bottom and a water outlet at the top. However, this is not limiting. In specific implementations of the invention, a water pump can be installed inside the receiving cavity 11, a water flow channel can be provided at the axis of the water-spinning component, and a water outlet communicating with the water flow channel can be provided circumferentially on the side wall of the water-spinning component. The water outlet of the water pump is connected to the water inlet through a pipeline so that the water pump can deliver liquid water to the water flow channel, so that when the water-spinning component rotates, the liquid water delivered by the water pump to the water flow channel can be thrown out through the water outlet.

[0059] Continue reading Figure 1 and Figure 2 In a specific implementation of this invention, the sterilization component 3 includes a hydrogen peroxide module, which is located on the bottom wall of the receiving cavity 11. This module is used to generate hydrogen peroxide by electrolyzing the liquid water in the receiving cavity 11, ensuring that the liquid water is mixed with hydrogen peroxide. This arrangement allows the sterilization component 3 to directly generate a sterilizing agent from the liquid water during the operation of the air purifier 100, avoiding the need for a separate sterilizing agent dispensing device and reducing the number of parts. Furthermore, it eliminates the need for the user to manually add sterilizing agent to the sterilization component 3, making air purification more convenient and improving user satisfaction.

[0060] It should be noted that although the above is combined Figure 1 The sterilization assembly 3 described above includes a hydrogen peroxide module, but this is not restrictive, and in the specific implementation of the present application, the sterilization assembly 3 can also be a sterilization agent feeding module. Specifically, the sterilization assembly 3 is arranged in the accommodation cavity 11 and is used to feed the sterilization agent contained in the sterilization assembly 3 to the liquid water, so that the liquid water in the accommodation cavity 11 can mix with the sterilization agent. The sterilization agent can be a sterilization product such as hypochlorous acid disinfectant, chlorhexidine, chlorine dioxide, and povidone, which has a sterilization function on bacteria, viruses, and fungi.

[0061] Continuing to refer to Figure 1 and Figure 2 In the specific implementation of the present application, the air purification device 100 further comprises a filter assembly 4 arranged at the air outlet 12 of the accommodation cavity 11 and configured to be able to absorb the liquid water in the water mist, so that the filter assembly 4 can have hydrogen peroxide attached therein, so that the filter assembly 4 can sterilize the air flowing therethrough, so that the air purification module 1 can effectively sterilize the air, thereby ensuring the sterilization effect of the air purification module 1. Specifically, the filter assembly 4 comprises a bracket 41 and a wet film 42, the bracket 41 is arranged on the air outlet 12, and the wet film 42 is arranged on the bracket 41 and is used to absorb the liquid water in the water mist.

[0062] Although the above is combined Figure 1 The filter assembly 4 described above comprises a bracket 41 and a wet film 42, but this is not restrictive, and in the specific implementation of the present application, the filter assembly 4 can be a filter wool. Obviously, the filter assembly 4 can also comprise activated carbon, synthetic fiber filter screen, and other products with filtering function.

[0063] Preferably, in the specific implementation of the present application, the air purification device 100 further comprises a humidity sensor and a colony detector. The humidity sensor is arranged at the air inlet 13 of the accommodation cavity 11 and is used to detect the current air humidity of the indoor air. The colony detector is arranged at the air inlet 13 of the accommodation cavity 11 and is used to detect the number of colonies in the air flowing through the air inlet 13 of the accommodation cavity 11. Specifically, the colony detector comprises a biological aerosol detector. More specifically, the biological aerosol detector is a device integrating a large-flow collection module, a rapid fluorescence detection module, a cleaning module, and the like. It realizes full-automatic unattended detection, has high sensitivity and high stability, and can quickly respond and accurately capture the change of microbial concentration in a short time.

[0064] In the present application, the air purification device 100 further comprises a controller (not shown) connected with the water throwing assembly 2, the bacteria removing assembly 3, the fan, the humidity sensor and the bacteria colony detector respectively, so that the controller can control the operation parameters of the water throwing assembly 2, the bacteria removing assembly 3 and the fan based on the current air humidity and the number of bacteria colonies in the indoor air, so that the air purification device 100 of the present application can sterilize the indoor air in a targeted manner. It should be noted that the controller can be a control chip possessed by the clothes care device itself, or a control module specially used for executing the control method of the present application, or a functional unit of the control module.

[0065] The possible implementation of the control method of the air purification device of the present application will be described below with reference to Figures 3-6 .

[0066] As shown in Figure 3 , in one possible implementation, the possible implementation of the control method of the air purification device of the present application comprises the following steps:

[0067] S101: obtaining a control instruction, the control instruction comprising a target air humidity;

[0068] S102: obtaining air parameters, the air parameters comprising a current air humidity and a number of bacteria colonies;

[0069] S103: determining operation parameters of the air purification device according to the control instruction and the air parameters.

[0070] In S101, the control instruction is input by a user through a control panel (not shown) provided on the shell of the air conditioner, and the control instruction comprises a target air humidity selected by the user. It should be noted that although the above description is that the user inputs the control instruction through the control panel, this is not limiting, and in the specific implementation of the present application, the control instruction can also be input through a mobile terminal.

[0071] In S102, the air humidity in the room is obtained by the humidity sensor, and the number of bacteria colonies in the indoor air is obtained by the bacteria colony detector, wherein the number of bacteria colonies is the number of bacteria colonies contained in a unit volume of air.

[0072] In S103, the operation parameters of the air purification device are controlled according to the target air humidity contained in the control instruction, the current air humidity and the number of bacteria colonies, so that the air purification device can sterilize the air in the room while adjusting the air humidity in the room.

[0073] As shown in Figure 4 , in one possible implementation, the possible implementation of the control method of the air purification device of the present application comprises the following steps:

[0074] S201: Call the preset first mapping table that stores the correspondence between the current air humidity, target air humidity, number of colonies, water-spinning power of the water-spinning component and sterilization power of the sterilization component.

[0075] S202: Determine the water-spraying power and sterilization power based on the current air humidity, target air humidity, number of colonies, and the first mapping relationship table.

[0076] In S201, the controller stores a first mapping table showing the correspondence between current air humidity, target air humidity, colony count, water-spinning power of the water-spinning component, and sterilization power of the sterilization component. Specifically, in this embodiment of the invention, the water-spinning power of the water-spinning component is the driving power of the drive unit, i.e., the power of the drive motor. The sterilization power of the sterilization component is the electrolysis power of the hydrogen peroxide module. It should be noted that although the first mapping table described above is pre-stored inside the controller, this is not limiting. The controller can also be configured to match the corresponding first mapping table in a local database, cloud database, or network database according to the received control commands.

[0077] Furthermore, although the water-spraying power and sterilization power described above refer to the driving power of the drive motor and the electrolysis power of hydrogen peroxide, this is not limiting. In other embodiments of the present invention, the water-spraying power can be the power of the water pump of the water-spraying component, and the sterilization power of the sterilization component can be the power of the sterilization component in dispensing the sterilizing agent. Without departing from the basic principles of the present invention, those skilled in the art can flexibly choose the configuration of the water-spraying component according to the specific application scenario, as long as the controller can adjust the generation rate of water mist inside the containing chamber by controlling the water-spraying component. Similarly, without departing from the basic principles of the present invention, those skilled in the art can flexibly choose the configuration of the sterilization component according to the specific application scenario, as long as the controller can adjust the rate at which the sterilization component adds the sterilizing agent to the liquid water.

[0078] In S202, after the controller receives the current air humidity, target air humidity, and colony count, it can call a first mapping table pre-stored within the controller and compare the called first mapping table with the current air humidity, target air humidity, and colony count. This allows the controller to determine the power of the drive unit and the electrolysis power of the hydrogen peroxide module based on the current air humidity, target air humidity, and colony count. Through this setting, when the humidity sensor detects a difference greater than zero between the target indoor air humidity and the current air humidity, the controller can increase the water-spinning power of the water-spinning component, i.e., increase the speed at which the water-spinning component generates water mist inside the containment cavity. This increases the humidification speed of the humidification module during the operation of the air purification device, thereby increasing the current indoor air humidity. Specifically, in the specific implementation of this invention, the correspondence between the current air humidity, target air humidity, colony count, water-spinning power of the water-spinning component, and electrolysis power of the hydrogen peroxide module can be generated by the designer based on training. Similarly, when the difference between the number of colonies detected by the colony detector and the standard value is greater than zero, the controller can increase the electrolysis power of the hydrogen peroxide module, that is, increase the concentration of hydrogen peroxide mixed in the liquid water. This will increase the concentration of hydrogen peroxide in the water mist, thereby increasing the sterilization speed of the water mist on the colonies in the air, and thus reducing the number of colonies in the indoor air.

[0079] like Figure 5 As shown, in one possible implementation, the control method of the air purification device of the present invention may include the following steps:

[0080] S301: Call the preset second mapping table that stores the corresponding relationships between the current air humidity, target air humidity, number of colonies, water-spinning power of the water-spinning component, sterilization power of the sterilization component, and fan speed.

[0081] S302: Determine the fan speed, water-spraying power, and sterilization power based on the current air humidity, target air humidity, colony count, and the second mapping table.

[0082] In S301, the controller stores a second mapping table showing the correspondence between current air humidity, target air humidity, colony count, water-spinning power of the water-spinning component, sterilization power of the sterilization component, and fan speed. Specifically, in this embodiment, the water-spinning power of the water-spinning component is the driving power of the drive unit, i.e., the power of the drive motor. The sterilization power of the sterilization component is the electrolysis power of the hydrogen peroxide module. It should be noted that although the second mapping table described above is pre-stored inside the controller, this is not limiting. The controller can also be configured to match the corresponding second mapping table in a local database, cloud database, or network database according to the received control commands.

[0083] In S302, after the controller receives the current air humidity, target air humidity, and colony count, the controller can call the second mapping table pre-stored inside the controller and compare the called second mapping table with the current air humidity, target air humidity, and colony count. In this way, the controller can determine the power of the drive unit, the electrolysis power of the hydrogen peroxide module, and the fan speed of the fan based on the current air humidity, target air humidity, and colony count. By using the above settings, when the humidity sensor detects that the difference between the target indoor air humidity and the current air humidity is greater than zero, the controller can increase the water-spinning power of the water-spinning component and the fan speed, that is, increase the speed at which the water-spinning component generates water mist inside the receiving cavity. On this basis, increasing the fan speed can further increase the speed at which the water mist is delivered to the room through the air outlet to produce humid air. In this way, during the operation of the air purification device, the humidification speed of the humidification module can be further improved, thereby increasing the current indoor air humidity. Specifically, in the specific implementation of this invention, the correspondence between the current air humidity, target air humidity, colony count, water-spinning power of the water-spinning component, electrolysis power of the hydrogen peroxide module, and fan speed can be generated by the designer based on training. Similarly, when the difference between the number of colonies detected by the colony detector and the standard value is greater than zero, the controller can increase the electrolysis power of the hydrogen peroxide module, that is, increase the concentration of hydrogen peroxide mixed in the liquid water. This will increase the concentration of hydrogen peroxide in the water mist. On this basis, the fan speed can be reduced so that the air entering the containment chamber can come into more full contact with the water mist, thereby further increasing the sterilization speed of the water mist on the colonies in the air, and thus reducing the number of colonies in the indoor air.

[0084] like Figure 6 As shown, in one possible implementation, the control method of the air purification device of the present invention may include the following steps:

[0085] S401: Call the preset third mapping table that stores the correspondence between current air humidity, target air humidity, number of colonies, sterilization power of sterilization components and fan speed;

[0086] S402: Determine the fan speed and sterilization power based on the current air humidity, target air humidity, colony count, and the third mapping table.

[0087] In S401, the controller stores a third mapping table showing the correspondence between current air humidity, target air humidity, colony count, sterilization power of the sterilization component, and fan speed. Specifically, in this embodiment, the sterilization power of the sterilization component is the electrolysis power of the hydrogen peroxide module. It should be noted that although the third mapping table described above is pre-stored within the controller, this is not limiting. The controller can also be configured to match the corresponding third mapping table in a local database, cloud database, or network database based on received control commands.

[0088] In step S402, after the controller receives the current air humidity, target air humidity, and colony count, it can call a third mapping table pre-stored within the controller and compare the called third mapping table with the current air humidity, target air humidity, and colony count. This allows the controller to determine the electrolysis power of the hydrogen peroxide module and the fan speed based on these parameters. Through this configuration, when the humidity sensor detects a difference greater than zero between the target indoor air humidity and the current air humidity, the controller can increase the fan speed, thereby increasing the speed at which water mist is delivered into the room through the air outlet. This further enhances the humidification speed of the humidification module during air purification, ultimately increasing the current indoor air humidity. Specifically, in this invention, the correspondence between the current air humidity, target air humidity, colony count, electrolysis power of the hydrogen peroxide module, and fan speed can be generated by the designer based on training. Similarly, when the difference between the number of colonies detected by the colony detector and the standard value is greater than zero, the controller can increase the electrolysis power of the hydrogen peroxide module, that is, increase the concentration of hydrogen peroxide mixed in the liquid water. This will increase the concentration of hydrogen peroxide in the water mist. On this basis, the fan speed can be reduced so that the air entering the containment chamber can come into more full contact with the water mist, thereby further increasing the sterilization speed of the water mist on the colonies in the air, and thus reducing the number of colonies in the indoor air.

[0089] Furthermore, those skilled in the art will understand that all or part of the processes in the control method of the present invention can be implemented by a computer program instructing related hardware. The computer program can be stored in a computer-readable storage medium, and when executed by a processor, it can implement the steps of the various method embodiments described above. The computer program includes computer program code, which includes, but is not limited to, program code for executing the methods corresponding to the control module functions in the aforementioned wastewater recycling device. For ease of explanation, only the parts relevant to the present invention are shown. The computer program code can be in the form of source code, object code, executable files, or certain intermediate forms.
