When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
Fig. 1 is a schematic structural view of an embodiment of an air cleaner of the present application, and fig. 2 is a schematic structural view of a cleaner body of fig. 1, and as shown in fig. 1 to 2, the air cleaner of the present application includes a cleaner body 100, and a control device 200 of the air cleaner connected to the cleaner body 100. Wherein, an openable and closable activated carbon formaldehyde filter screen 11 is arranged on the air channel between the air inlet and the air outlet of the purifier body 100; the control device 200 of the air purifier is used for determining the current formaldehyde purification control mode of the air purifier; operating a formaldehyde purification control mode to generate an opening and closing instruction of the activated carbon formaldehyde filter screen corresponding to the formaldehyde purification control mode; and controlling the opening and closing state of the activated carbon formaldehyde filter screen 11 according to the opening and closing instruction of the activated carbon formaldehyde filter screen.
It should be understood that the activated carbon formaldehyde filter screen 11 is a filter screen specially used for filtering formaldehyde, and usually cannot be used alone, but must be installed in other equipment to filter and adsorb formaldehyde in air. Meanwhile, the activated carbon formaldehyde filter screen belongs to consumable products and can not be recycled under common conditions.
In the purifier main body provided by the application, the air channel between the air inlet and the air outlet is provided with the openable activated carbon formaldehyde filter screen; determining a current formaldehyde purification control mode of the air purifier; operating a formaldehyde purification control mode to generate an opening and closing instruction of the activated carbon formaldehyde filter screen corresponding to the formaldehyde purification control mode; and controlling the opening and closing state of the activated carbon formaldehyde filter screen according to the opening and closing instruction of the activated carbon formaldehyde filter screen. So set up the switching state that can pass through to change the active carbon formaldehyde filter screen, reduce the active carbon formaldehyde filter screen and maintain the time at the closure state to this life who prolongs the active carbon formaldehyde filter screen, in order to reduce the frequency of changing the formaldehyde filter screen.
Specifically, referring to fig. 2 and 4, the present embodiment describes the technical solution of the present application with a specific air purifier. The application provides an inside active carbon formaldehyde filter screen 11 of air purifier is the active carbon formaldehyde filter screen that can open and close. Wherein the openable activated carbon formaldehyde filter screen may include: two pages of active carbon formaldehyde filter screen sub-sheets 111 and a rotating part 112 which can be spliced. But two pages of active carbon formaldehyde filter screen sub-pieces 111 of amalgamation are connected on the wind channel of clarifier body through rotating part 112 respectively, and when the active carbon formaldehyde filter screen was opened, through rotating part 112 make two pages of active carbon formaldehyde filter screen sub-pieces 111 of amalgamation be on a parallel with the wind channel, but the air current in the wind channel so can need not the active carbon formaldehyde filter screen sub-piece through the amalgamation and pass the wind channel. When the active carbon formaldehyde filter screen is closed, the two pages of the two-page splicing active carbon formaldehyde filter screen sub-sheet 111 is perpendicular to the direction of the air duct by rotating the rotating part 112, the two pages of splicing active carbon formaldehyde filter screen sub-sheet can be spliced into a whole active carbon formaldehyde filter screen 11 and separates the air duct, so that the air flow in the air duct must pass through the air duct through the active carbon formaldehyde filter screen, and the purpose of purifying the formaldehyde passing through the air duct is achieved. Thus, when the concentration of formaldehyde is higher, the formaldehyde in the air is purified by closing the activated carbon formaldehyde filter screen 11. When the concentration of formaldehyde is lower, the use time of the activated carbon formaldehyde filter screen is shortened by opening the activated carbon formaldehyde filter screen 11, so that the service life of the activated carbon formaldehyde filter screen is prolonged.
Further, referring to fig. 3 and 4, in the technical solution provided by the present application, an air duct between the air inlet and the air outlet of the purifier body is further provided with an openable porous photocatalytic module 12; the control device 200 of the air purifier is also used for generating a porous photocatalytic module opening and closing instruction corresponding to the formaldehyde purification control mode when the formaldehyde purification control mode is operated; and controlling the open-close state of the porous photocatalytic module 12 according to the open-close command of the porous photocatalytic module.

Two pages of openable porous photocatalytic module sub-sheets 121 are connected to the air duct of the purifier body through the rotating part respectively, the ultraviolet lamp 123 is arranged on the air duct of the purifier body, and the ultraviolet rays are emitted towards the positions of the two pages of openable porous photocatalytic module sub-sheets when the two pages of porous photocatalytic module sub-sheets are closed. When the porous photocatalytic module is opened, the ultraviolet lamp 123 is closed, and the two openable and closable porous photocatalytic module sub-sheets 121 are parallel to the air duct by rotating the rotating member 122, so that the air flow in the air duct can pass through the air duct without passing through the openable and closable porous photocatalytic module sub-sheets. When the porous photocatalytic module 12 is closed, the two openable and closable porous photocatalytic module sub-sheets 121 are perpendicular to the air duct direction by rotating the rotating part 122, the two openable and closable porous photocatalytic module sub-sheets 121 can be spliced into the whole porous photocatalytic module 12 and cut off the air duct, the ultraviolet lamp 123 is opened and emits ultraviolet rays to the porous photocatalytic module 12, and thus, the air flow in the air duct must pass through the air duct through the activated carbon formaldehyde filter screen, and the aim of purifying formaldehyde passing through the air duct is fulfilled. Therefore, when the concentration of formaldehyde is higher, the formaldehyde in the air is purified by closing the activated carbon formaldehyde filter screen. When formaldehyde concentration is lower, through opening the active carbon formaldehyde filter screen, the closed open closed porous photocatalysis module reduces the live time of active carbon formaldehyde filter screen, utilizes porous photocatalysis module to purify formaldehyde to reach when purifying formaldehyde, prolong the life's of active carbon formaldehyde filter screen purpose.
