[0038] Hereinafter, with reference to the accompanying drawings, an air handling apparatus 100 according to a first aspect embodiment of the present invention will be described.

[0039] like Figure 1 and Figure 2 As shown, the air handling device 100 includes a housing 1, and a receiving cavity 10 is defined inside the housing 1. The receiving cavity 10 has a first opening 10a and a second opening 10b. The first opening 10a and the second opening 10b are spaced apart. The first opening 10a and the second opening 10b can penetrate the housing 1 along the thickness direction of the housing 1, so that the first opening 10a and the second opening 10b are respectively connected to the receiving cavity 10.

[0040] The air treatment device 100 further comprises an adsorption assembly 2 and a driving assembly 3, the adsorption assembly 2 comprises a first adsorption part 21 and a second adsorption part, the first adsorption part 21 and the second adsorption part can be used for adsorbing air pollutants to treat air, so as to achieve the effect of purifying air, the driving assembly 3 is used for driving the first adsorption part 21 to extend out of the containing cavity 10 through the first opening 10a, and the second adsorption part is accommodated in the containing cavity 10, the driving assembly 3 is also used for driving the second adsorption part to extend out of the containing cavity 10 through the second opening 10b, and the first adsorption part 21 is accommodated in the containing cavity 10, then the adsorption assembly 2 can have a first working state and a second working state, and the driving assembly 3 can switch the adsorption assembly 2 between the first working state and the second working state, in the first working state, the first adsorption part 21 extends out of the containing cavity 10, and the second adsorption part is accommodated in the containing cavity 10, at this time, the first adsorption part 21 is used for purifying air, in the second working state, the second adsorption part extends out of the containing cavity 10, and the first adsorption part 21 is accommodated in the containing cavity 10, at this time, the second adsorption part is used for purifying air.

[0041] Among them, since the first opening 10a and the second opening 10b are arranged at intervals, it is convenient to avoid interference between the first adsorption part 21 and the second adsorption part, and the requirement for the relative length between the first adsorption part 21 and the second adsorption part can be reduced. For example, the air pollutants can be VOC (volatile organic compounds) s , including toluene, xylene, formaldehyde, alcohol, etc., the adsorption assembly 2 can adsorb VOC s in the air to improve air quality.

[0042] As shown in Figure 2 , Figure 4 and Figure 5 , the air treatment device 100 further comprises a photocatalytic assembly 4, the photocatalytic assembly 4 is used for decomposing pollutants adsorbed by the first adsorption part 21 or the second adsorption part in the containing cavity 10, decomposing harmful substances into harmless substances, so as to realize the desorption treatment of the first adsorption part 21 or the second adsorption part, thereby the problem of frequent replacement of the adsorption assembly 2 due to saturation of the adsorption assembly 2 can be solved.

[0043] For example, when the adsorption assembly 2 is in the first working state, the first adsorption part 21 is completely located outside the containing cavity 10 for purifying air, at this time, if the second adsorption part reaches adsorption saturation or approaches adsorption saturation, the photocatalytic assembly 4 decomposes the pollutants of the second adsorption part, so that when the first adsorption part 21 reaches adsorption saturation or approaches adsorption saturation, the adsorption assembly 2 can be directly switched to the second working state, so that the second adsorption part is completely located outside the containing cavity 10 to continue purifying air, at this time, the first adsorption part 21 is accommodated in the containing cavity 10 and is subjected to desorption treatment under the action of the photocatalytic assembly 4, so that when the second adsorption part needs to be desorbed, the adsorption assembly 2 is directly switched to the first working state again, thereby facilitating the air treatment device 100 to continuously purify air for a long time to remove pollutants such as gaseous pollutants in the air.

[0044] According to the air treatment device 100 of the embodiment of the present application, by arranging the driving assembly 3 to drive the first adsorption part 21 to extend outside the containing cavity 10 through the first opening 10a and the second adsorption part to be accommodated in the containing cavity 10, the driving assembly 3 is also used to drive the second adsorption part to extend outside the containing cavity 10 through the second opening 10b and the first adsorption part 21 to be accommodated in the containing cavity 10, and the photocatalytic assembly 4 is used to decompose the pollutants adsorbed by the first adsorption part 21 or the second adsorption part located in the containing cavity 10, so as to realize the renewable use of the first adsorption part 21 or the second adsorption part, thereby enabling the first adsorption part 21 to be used for purifying air while the second adsorption part completes renewable use, and enabling the second adsorption part to be used for purifying air while the first adsorption part 21 completes renewable use, thereby facilitating the air treatment device 100 to continuously and effectively remove pollutants such as gaseous pollutants in the air for a long time.

[0045] In some embodiments, the driving assembly 3 can include a driving wheel arranged in the containing cavity 10, and the driving wheel has a first gear part, and the adsorption assembly 2 has a second gear part which is engaged with the first gear part, so that when the driving wheel rotates, a large driving force can be applied to the adsorption assembly 2, so as to ensure that the adsorption assembly 2 can smoothly extend outside the containing cavity 10 or be accommodated in the containing cavity 10 by overcoming the movement resistance.

[0046] It can be understood that the driving assembly 3 can be connected with a driving device such as a motor, so as to realize the operation of the driving assembly 3; or the driving assembly 3 can also be operated by an operator, so as to realize the operation of the driving assembly 3.

[0047] In some embodiments of the present application, as shown in Figure 2 and Figure 5As shown, the first opening 10a and the second opening 10b are located at the same side of the shell 1, so that the first adsorption part 21 extending out of the containing cavity 10 and the second adsorption part extending out of the containing cavity 10 are located at the same side of the shell 1, which is beneficial to make the first adsorption part 21 and the second adsorption part purify the airflow at the same air vent (for example, the air inlet of the air outlet device, or the air outlet, or any position of the air duct between the air inlet and the air outlet).

[0048] For example, in the examples of Figure 2 and Figure 5 , the first opening 10a and the second opening 10b are both located at the right side of the shell 1, then the first adsorption part 21 can extend out of the containing cavity 10 to the right, and the second adsorption part can also extend out of the containing cavity 10 to the right.

[0049] Further, the first opening 10a and the second opening 10b can be adjacent, so that the distance between the first adsorption part 21 extending out of the containing cavity 10 and the second adsorption part extending out of the containing cavity 10 can be reduced, which is beneficial to further ensure that the first adsorption part 21 and the second adsorption part purify the airflow at the same position.

[0050] Of course, the first opening 10a and the second opening 10b can also be located at different sides of the shell 1 according to actual application, for example, the first opening 10a is located at the left side of the shell 1, and the second opening 10b is located at the right side of the shell 1.

[0051] In some embodiments of the present application, as shown in Figure 1 , Figure 2 , Figure 4 and Figure 5 , the shell 1 comprises a first mounting part 11, the first mounting part 11 is arranged at the first opening 10a, the first adsorption part 21 is suitable for pullable cooperation with the first mounting part 11, and the first adsorption part 21 is suitable for being arranged opposite to the through opening of the first mounting part 11. The first mounting part 11 can play a certain guiding and supporting role for the first adsorption part 21, and the airflow can flow to the first adsorption part 21 through the through opening, so that the first mounting part 11 will not block the airflow flowing to the first adsorption part 21; when the air treatment device 100 is used in an air outlet device such as an air conditioner, the first mounting part 11 can be arranged at the air vent of the air outlet device, and the first adsorption part 21 cooperates with the first mounting part 11, so as to cover a larger area of the air vent, thereby ensuring the purification effect of the air, and at the same time, the user can not need to frequently disassemble the first adsorption part 21, which is beneficial to realize intelligent control of the air treatment device 100 and improve the practicability.

[0052] The shell 1 further comprises a second mounting portion 12 arranged at the second opening 10b, the second mounting portion 12 is suitable for being pullably matched with the second adsorption portion, and the second adsorption portion is suitable for being arranged opposite to the through opening of the second mounting portion 12. The second mounting portion 12 can play a guiding and supporting role on the second adsorption portion, and the airflow can flow to the second adsorption portion through the through opening, so that the second mounting portion 12 will not block the airflow flowing to the second adsorption portion. When the air treatment device 100 is used in an air outlet device such as an air conditioner, the second mounting portion 12 can be arranged at the air vent of the air outlet device, and the second adsorption portion is matched with the second mounting portion 12, so as to cover a larger area of the air vent, thereby ensuring the purification effect on the air, and at the same time, the user can not need to frequently disassemble and assemble the second adsorption portion, which facilitates the intelligent control of the air treatment device 100 and improves the practicability.

[0053] Optionally, the first mounting portion 11 and the second mounting portion 12 can respectively comprise two guide grooves arranged opposite to each other, and the opposite two ends of the first adsorption portion 21 are respectively suitable for being pullably inserted into the guide grooves of the first mounting portion 11, and the opposite two ends of the second adsorption portion are respectively suitable for being pullably inserted into the guide grooves of the second mounting portion 12. In this way, the first mounting portion 11 and the second mounting portion 12 are simple in structure and facilitate smooth movement of the adsorption assembly 2.

[0054] Optionally, the first mounting portion 11 and the second mounting portion 12 can be an integral piece.

[0055] Of course, the air treatment device 100 can also not comprise the first mounting portion 11 and the second mounting portion 12, and when the first adsorption portion 21 and the second adsorption portion extend out of the accommodating cavity 10, they can be detachably arranged at the air vent through other modes.

[0056] In some embodiments of the present application, as shown in Figure 1 、 Figure 2 、 Figure 4 and Figure 5 , the first mounting portion 11 and the second mounting portion 12 are suitable for being stacked along the airflow direction. For example, in the airflow direction, the second mounting portion 12 can be located upstream of the first mounting portion 11, at this time, the airflow first flows through the second mounting portion 12 and then flows through the first mounting portion 11, or the second mounting portion 12 is located downstream of the first mounting portion 11, at this time, the airflow first flows through the first mounting portion 11 and then flows through the second mounting portion 12. In this way, it is convenient to ensure that the first adsorption portion 21 and the second adsorption portion purify the airflow at the same air vent.

[0057] In Figure 1 、 Figure 2 、 Figure 4 and Figure 5In the example shown in FIG. 1, the first mounting portion 11 and the second mounting portion 12 are arranged in close proximity to each other, and the first mounting portion 11 and the second mounting portion 12 are connected to each other, thereby effectively reducing the distance between the first adsorption portion 21 extending into the accommodating cavity 10 and the second adsorption portion extending into the accommodating cavity 10, and ensuring that the first adsorption portion 21 and the second adsorption portion purify the airflow at the same position.

[0058] In some embodiments of the present application, as shown in Figure 2 、 Figure 4 and Figure 5 , the photocatalytic assembly 4 includes a catalytic light source 41 and a photocatalytic module 42, the catalytic light source 41 is arranged in the accommodating cavity 10, and the photocatalytic module 42 includes a support carrier and a photocatalyst, the photocatalyst is arranged on at least one side surface of the support carrier facing the catalytic light source 41, and the photocatalyst can excite active oxidants under the action of the catalytic light source 41, thereby effectively decomposing the pollutants on the first adsorption portion 21 or the second adsorption portion, decomposing the harmful substances into harmless substances, and achieving desorption treatment.

[0059] Optionally, when the pollutants are VOCs s , the catalytic light source 41 can be an ultraviolet lamp or an infrared lamp, the photocatalyst includes one or more of titanium oxide, manganese oxide, zinc oxide, cerium oxide, and nano-resistive graphene, and the support carrier is a foamed nickel piece, a honeycomb aluminum piece, or a porous ceramic piece, etc.

[0060] For example, the support carrier can be a porous structure including a plurality of through holes, and the photocatalyst can also be arranged on the wall surface of the through holes, thereby increasing the setting area of the photocatalyst, improving the catalytic effect under the action of the catalytic light source 41, increasing the contact area between the air and the photocatalyst, and being beneficial to improving the desorption efficiency.

[0061] Further, the photocatalytic assembly 4 further includes a flow disturbing component 43 and / or a heating component, and the photocatalytic assembly 4 includes the following schemes: 1, the photocatalytic assembly 4 includes the flow disturbing component 43; 2, the photocatalytic assembly 4 includes the heating component; 3, the photocatalytic assembly 4 includes the flow disturbing component 43 and the heating component. The flow disturbing component 43 is used to disturb the airflow in the accommodating cavity 10, so that the airflow in the accommodating cavity 10 can better contact the photocatalyst, so as to facilitate the photocatalytic module 42 to completely catalytically decompose the pollutants within a certain time, and ensure the desorption effect and the desorption efficiency; the heating component is arranged in the accommodating cavity 10, and is used to heat the first adsorption portion 21 or the second adsorption portion, which is beneficial to improving the desorption efficiency.

[0062] Optionally, the flow disturbing component 43 can be a fan.

[0063] Optionally, a turbulence component 43 is arranged in the accommodation cavity 10, so as to ensure that the turbulence component 43 effectively disturbs the air flow in the accommodation cavity 10. It can be understood that the specific arrangement position of the turbulence component 43 can be arranged according to actual application.

[0064] In some embodiments of the present application, as shown in Figure 2 , Figure 5 The accommodation cavity 10 has a mounting channel 10c, the mounting channel 10c is curved, and the two ends of the mounting channel 10c are in communication with the first opening 10a and the second opening 10b respectively, and the first adsorption part 21 and the second adsorption part are adapted to be pullably fitted with the mounting channel 10c, so that the first adsorption part 21 or the second adsorption part is smoothly extended out of the accommodation cavity 10 or smoothly accommodated in the accommodation cavity 10, and at the same time, due to the fact that the mounting channel 10c is curved, the first adsorption part 21 or the second adsorption part accommodated in the accommodation cavity 10 extends along the mounting channel 10c, so that the first adsorption part 21 or the second adsorption part is also curved when it is accommodated in the accommodation cavity 10, which is beneficial to reduce the occupied space when the first adsorption part 21 or the second adsorption part is accommodated in the accommodation cavity 10, and facilitates the reduction of the volume of the air treatment device 100, and realizes the miniaturization design.

The catalytic light source 41 is arranged between each two adjacent extension sections 10d, and the photocatalytic module 42 is arranged between each extension section 10d and the corresponding catalytic light source 41.
