[0043] It should be noted that if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features specified as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the meaning of "and / or" appearing throughout the text is to include three parallel solutions. Taking "A and / or B" as an example, it includes Solution A, Solution B, or solutions that meet both A and B.

[0044] The present invention proposes an air treatment device that can be used alone or in equipment such as air conditioners, purifiers, and air machines. The air conditioner can be a split-type air conditioner, such as a floor-standing air conditioner or a wall-mounted air conditioner, or an integrated air conditioner, such as a window air conditioner or a mobile air conditioner.

[0045] In the embodiment of the present invention, Figures 1 to 4 As shown, the air treatment device 100 includes a housing 110 and a first purification module, which is a live purification module 130. Housing 110 has an air inlet, an air outlet 112, and an air duct 113 connecting the air inlet and outlet 112. Air duct 113 is provided with a first mounting position 114b and a second mounting position 114a, with the first mounting position 114b located below the second mounting position 114a. Live purification module 130 is mounted in the first mounting position 114b.

[0046] In this embodiment, the shell 110 as a whole can be in the shape of a cube, a rectangular parallelepiped, a cylinder, a special shape, etc. The air duct 113 can be formed by the entire inner cavity of the shell 110. Usually, a fan 150 is also provided in the air duct 113 to drive the air flow from the air inlet into the air duct 113 and blown out from the air outlet 112. Specifically, the air inlet includes a fresh air inlet 111 and / or an indoor air inlet 118. When the air treatment device 100 is installed in the air conditioner for use, the fan 150 is provided with a mounting plate for assembling and fixing the fan 150 to the columns on both sides of the rear shell of the air conditioner indoor unit. The air inlet and the air outlet 112 are usually opened on different sides of the shell 110. In order to ensure the consistency of the appearance of the air treatment device 100, the air inlet is usually set on the rear side of the shell 110. The air outlet 112 can be opened on the left and right sides of the shell 110, or on the top wall or front side of the shell 110. The specific opening position of the air outlet 112 can be selected and designed according to actual use requirements and is not limited here. The number of air outlets 112 is at least one, and the number of air outlets 112 can be selected according to needs, such as one, two or three. A guide sealing structure is provided at the air outlet 112 of the shell 110, which is sealed with the casing air outlet 210 provided on the casing 200 of the air conditioner indoor unit through the guide sealing structure. The shape of the fresh air inlet and the air outlet can be selected according to actual needs, for example, it can be circular, rectangular, long strip, etc.

[0047] A single charged purification module 130 can be installed in the air duct 113, or multiple charged purification modules 130 can be installed, such that the multiple charged purification modules 130 are arranged along the air outlet direction of the air duct 113. When the air treatment device 100 includes two or more charged purification modules 130, the functions of each charged purification module 130 can be the same or different. It should be noted that the charged purification module 130 refers to a purification module that requires power to perform its purification function. The charged purification module 130 can specifically include a sterilization module, a plasma module 132, or an electric purification module. The sterilization module can specifically be a negative ion module. The electric purification module can specifically be a dust removal and filtration module such as an electrostatic dust removal module 131. The charged purification module 130 can be fixedly mounted on the first mounting position 114b or can be removably mounted on the first mounting position 114b. The second mounting position 114a can be used to install other purification modules, such as a non-charged purification module or other modules that need to be frequently replaced. Compared with the uncharged purification module, the charged purification module 130 may not need to be replaced or may need to be replaced after a longer period of time.

[0048] The air treatment device 100 of the present invention provides a first mounting position 114b and a second mounting position 114a within the air duct 113, with the first mounting position 114b positioned below the second mounting position 114a. The live purification module 130 is mounted in the first mounting position 114b. This allows the live purification module, which does not require frequent removal or replacement, to be positioned below other modules, such as the non-live purification module. This effectively prevents electric shock to users and improves the overall layout.

[0049] In one embodiment, please refer again to Figures 1 to 4 The air treatment device 100 further includes a second purification module 120 . The second purification module 120 is a non-charged module. The second purification module 120 is installed at the second installation position 114 a .

[0050] In this embodiment, specifically, the second purification module 120 is detachably mounted on the second mounting position 114a. It should be noted that a non-powered module refers to a purification module that can perform a purification function without being powered on. Specifically, the purification module can be a filter module. The filter module is a primary filter, a medium-efficiency filter, a HEPA filter, a gaseous pollutant filter or an activated carbon filter. The gaseous pollutant filter can be a formaldehyde removal filter, a VOC removal filter, etc., and the formaldehyde filter can be a manganese dioxide catalytic formaldehyde removal filter. The number of second purification modules 120 can be set to one or more. When the air treatment device 100 includes two or more filter modules, the function of each filter module can be the same or different. Then the filter module is usually a consumable filter, which is frequently dirty and blocked and needs to be frequently replaced or cleaned.

[0051] It should be noted that the second purification module 120 experiences a higher frequency of fouling and clogging than the live purification module 130. This means that the second purification module 120 is more susceptible to fouling and has a shorter service life than the live purification module 130. Over the same period of time, the second purification module 120 requires replacement or cleaning more often than the live purification module 130. The frequency of fouling and clogging in the second purification module 120 and the live purification module 130 can be determined by comparing their pore size and pore density, or based on user experience.

[0052] In this way, the non-charged second purification module 10, which requires frequent replacement or disassembly for maintenance, is placed above the charged purification module 130. This allows users to remove or replace the filter module without bending or squatting, making it easier to do and improving the user experience. Furthermore, placing the charged purification module 130, which requires less frequent removal or replacement, below other modules, such as the non-charged purification module, effectively prevents electric shock and improves the overall layout.

[0053] Specifically, the charged purification module 130 is located at the lower part of the housing 110, and the second purification module 120 is located at the upper part of the housing 110. The upper part of the housing 110 is located above the middle of the housing 110, and the lower part of the housing 110 is located below the middle of the housing 110. In this way, the second purification module 120, which needs to be frequently replaced or frequently disassembled for maintenance, is placed in an easily removable position at the upper part of the housing 110. When the user needs to disassemble or replace the second purification module 120, they can disassemble the second purification module 120 without bending or squatting, which is convenient for user operation, improves the user experience, and can further prevent the user from electric shock.

[0054] In one embodiment, please refer to Figure 1 、 Figure 2 and Figure 4 The air treatment device 100 includes at least two second purification modules 120 stacked in the vertical direction of the air duct 113; and / or, the air treatment device 100 includes at least two charged purification modules 130 stacked in the vertical direction of the air duct 113. Providing at least two second purification modules 120 and at least two charged purification modules 130 can effectively improve and enhance the purification effect of the air treatment module. To achieve a better overall purification effect of the air treatment module, the functions of each second purification module 120 stacked in the vertical direction are different; and the functions of each charged purification module 130 stacked in the vertical direction are different. In this way, when the airflow in the air duct passes through the second purification module 120 and the charged purification module 130, it can be effectively and comprehensively purified by dust removal, sterilization, and other methods.

[0055] In reality, if Figure 1、 Figure 2 and Figure 4 As shown, the second mounting position 114a is a first mounting groove provided on the upper portion of the housing 110. An opening is provided on the front side of the first mounting groove, and the second purification module 120 can be installed in the first mounting groove in a retractable manner. The number of second mounting positions 114a corresponds to the number of second purification modules 120, so that each second purification module 120 is installed in a corresponding second mounting position 114a. The opening of the first mounting groove is provided on the front wall surface of the housing 110, so that the second purification module 120 can be installed in the second mounting position 114a or pulled out from the second mounting position 114a through the opening from the front side of the housing 110. The structure is simple and convenient for user operation. In order to facilitate the pulling and pulling of the second purification module 120, a slide groove structure can be provided on one of the inner wall surfaces of the second purification module 120 and the housing 110, and a slide rail structure can be provided on the other, so that the second purification module 120 is connected to the housing 110 in a slide groove and slide rail manner.

[0056] Furthermore, the first mounting position 114b is a second mounting groove provided at the lower part of the shell 110, and an opening is provided on the front side of the second mounting groove. The charged purification module 130 can be pulled out and installed in the second mounting groove. The air treatment device 100 also includes a lower cover plate 140, which can be detachably installed on the shell 110 to cover or open the opening of the first mounting position 114b.

[0057] In this embodiment, the number of first mounting positions 114b corresponds to the number of live purification modules 130, so that each live purification module 130 is installed in a corresponding first mounting position 114b. The opening of the first mounting position 114b is provided on the front wall of the housing 110, so that the live purification module 130 can be installed into or removed from the first mounting position 114b through the opening from the front side of the housing 110, resulting in a simple structure and convenient user operation. To facilitate the withdrawal and extraction of the live purification module 130, a slide groove structure can be provided on one of the inner wall of the live purification module 130 and the housing 110, and a slide rail structure can be provided on the other, so that the live purification module 130 is connected to the housing 110 in a slide groove and slide rail manner.

[0058] The opening of the second mounting slot is formed on the front wall of the housing 110, so that the live purification module 130 can be installed into the first mounting position 114b or pulled out from the first mounting position 114b through the opening from the front side of the housing 110. The lower cover 140 and the housing 110 can be detachably connected by means of snaps, screws, magnetism, etc. The shape of the lower cover 140 is adapted to the shape of the opening of the first mounting position 114b to effectively cover the opening of the first mounting position 114b. By using the lower cover 140 to detachably cover the opening of the first mounting position 114b, the live purification module 130 can be detachably installed in the first mounting position 114b while preventing the live purification module 130 from falling out of the first mounting position 114b. In addition, when the live purification module 130 is a live module, electric shock caused by user misoperation can be avoided.

[0059] In one embodiment, please refer to Figure 2 and Figure 4 The air treatment device 100 further includes a fan 150 installed in the housing 110. The fan 150 is located between the first installation position 114b and the second installation position 114a; or the fan 150 is located below the first installation position 114b.

[0060] In this embodiment, the air flow is driven by the fan 150 to enter the air duct 113 from the air inlet, and is blown out from the air outlet 112 after filtering and purification through the second purification module 120 and / or the charged purification module 130, thereby effectively improving the ventilation and purification efficiency of the air treatment device 100. The fan 150 can be a fresh air fan 150, so that the air inlet includes a fresh air inlet 111. In this way, the air treatment device 100 has a fresh air mode. In addition, the air treatment device 100 can also have an exhaust mode. An exhaust port and an indoor air inlet 118 connected to the outside can be additionally provided on the housing 110. An exhaust fan 150 is additionally provided or the fan 150 drives the indoor air flow from the indoor air inlet 118 into the air duct 113 and blown out to the outside through the exhaust port to achieve indoor sewage exhaust. Of course, the flow channel of the air duct 113 can be set and the type of fan 150 can be selected so that the exhaust port and the air inlet use the same port, and the exhaust fan 150 and the fresh air fan 150 use the same fan 150. The specific details are not limited here.

[0061] By locating the fan 150 between the first mounting position 114b and the second mounting position 114a, the purification modules are dispersed on the air inlet and air outlet sides of the fan 150. Compared to arranging the purification modules on one side of the fan 150, the wind resistance of the fan 150 can be effectively reduced, the overall air volume and purification efficiency can be improved, and the overall layout is more reasonable and easier for users to operate. By locating the fan 150 below the first mounting position 114b, both the first mounting position 114b and the second mounting position 114a are located above the fan 150, making it easier for users to operate the modules installed on the first mounting position 114b and the second mounting position 114a.

[0062] In one embodiment, if Figure 1 、 Figure 2 and Figure 4 As shown, the air treatment device 100 further includes a humidifier 160 and a water tank 171 . The humidifier 160 is installed in the air duct 113 . The water tank 171 is used to supply water to the humidifier 160 and is located in front of the fan 150 .

[0063] In this embodiment, the water tank 171 can be arranged above the humidifying component 160 or below the humidifying component 160. The humidifying component 160 can specifically be an atomizing component or a wet film 162 component. The humidifying component 160 also has a water tank, and the atomizing component or the wet film 162 component is arranged in the water tank, so that the water tank 171 supplies water to the water tank to achieve humidification of the room. The fan 150 can specifically be a centrifugal fan 150. Installing the water tank 171 on the front side of the fan 150 fully utilizes the space in front of the fan 150, making the structure of the entire air treatment device 100 more compact. By providing the humidifying component 160 and the water tank 171, the air treatment module has a humidification function, thereby diversifying the functions of the air treatment device 100 and improving product performance.

[0064] For further information, please refer to Figure 1 The front side of the housing 110 is formed with a concave mounting cavity 115, into which a water tank 171 is mounted. To facilitate refilling of the water tank 171, the water tank 171 is removably mounted. It will be appreciated that the mounting cavity 115 is isolated from the air duct 113 to prevent airflow from escaping. Humidification is achieved through the wet film 162, providing effective humidification and preventing bacterial growth. A lower water tank is formed at the lower end of the mounting cavity 115, into which the water tank 171 supplies water.

[0065] Specifically, the air treatment device 100 also includes a water pipe 172 and a water pump 173 mounted thereto. The humidifier 160 includes a humidifying bracket 161 and a wet membrane 162. The humidifying bracket 161 is formed with an upper water trough 161a, and the wet membrane 162 is mounted thereto. The water pump 173 supplies water to the upper water trough 161a via the water pipe 172. The water pump 173 pumps water from the lower water trough through the water pipe 172 into the upper water trough 161a of the humidifying bracket 161 to humidify the wet membrane 162. Alternatively, water can be poured directly from above the wet membrane 162. This ensures a more compact overall structure for the air treatment device 100 while maintaining effective humidification.

[0066] In one embodiment, if Figure 4 As shown, the air handling device 100 also includes an isolation member 190. A mounting opening 117 is provided on the front side of the housing 110. The isolation member 190 is detachably mounted at the mounting opening 117, and a mounting cavity 115 is formed. The isolation member 190 and the housing 110 are sealed, which can be achieved by using sealant, a sealing ring, or a structural seal. The mounting cavity 115 is formed in the isolation member 190, so that the water tank 171 is mounted in the isolation member 190, and the lower end of the isolation member 190 forms a lower water tank. By providing the mounting opening 117 on the front side of the housing 110, the isolation member 190 can be detachably mounted at the mounting opening 117. The fan 150 or other internal structures of the air duct 113 can be assembled from the mounting opening 117, so that the housing 110 can be provided as an integrated unit, simplifying the installation and manufacturing steps of the housing 110.

[0067] In one embodiment, if Figure 1 、 Figure 2 and Figure 4 As shown, the upper part of the shell 110 is provided with a third mounting position 114c which is open toward the front, and the humidification bracket 161 can be pulled out and installed in the third mounting position 114c. The side wall of the shell 110 is adjacent to the opening of the third mounting position 114c and is provided with a humidification water inlet 116 which is connected to the upper water tank 161a, and the upper end of the water pipe 172 is connected to the humidification water inlet 116.

[0068] In this embodiment, the opening of the third mounting position 114c is provided on the front wall of the housing 110, so that the humidifying bracket 161 can be installed into the third mounting position 114c or withdrawn from the third mounting position 114c from the front side of the housing 110 through the opening, facilitating replacement of the wet film 162. The structure is simple and user-friendly. To facilitate the withdrawal and extension of the humidifying bracket 161, a slide groove structure can be provided on one of the humidifying bracket 161 and the inner wall of the housing 110, and a slide rail structure can be provided on the other, so that the humidifying bracket 161 is connected to the housing 110 in a slide groove and slide rail manner.

[0069] A humidification water inlet 116 is provided at the opening of the third installation position 114c adjacent to the side wall of the shell 110. When the humidification bracket 161 is partially pulled out from the third installation position 114c and installed into the third installation position 114c, the humidification water inlet 116 is connected to the upper water trough 161a of the humidification bracket 161, thereby preventing the water in the water pipe 172 from flowing into the air duct 113 through the humidification water inlet 116 during the process of pulling out the humidification bracket 161, thereby preventing the fan 150 and other structural electrical components from being affected.

[0070] In one embodiment, please refer to Figures 2 to 4 A first sensor switch 181 is provided on the humidifying bracket 161, and a second sensor switch 182 is provided on the shell 110. When the humidifying bracket 161 is pulled out of the third installation position 114c, the first sensor switch 181 and the second sensor switch 182 move away from each other to control the fan 150 and / or the water pump 173 to stop running.

[0071] In this embodiment, the air treatment device 100 also has an electrical control box.
