[0034] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0035] refer to Figure 1 and Figure 2As shown, an embodiment of this application provides a fresh air filtration device 100, which includes a housing 110, a cover 120, a tray assembly 130, and a filter element 150.

[0036] Specifically, in combination Figure 2 and Figure 3 As shown, the housing 110 is provided with an opening 111 and a fresh air inlet 112. The opening direction of the opening 111 is angled to the opening direction of the fresh air inlet 112. The cover 120 covers the opening 111, and the cover 120 is detachably connected to the housing 110 and defines a receiving cavity 140. The fresh air inlet 112 on the housing 110 is used to introduce fresh outside air, and the receiving cavity 140 is used for the circulation and exchange of outside air.

[0037] It is understandable that the fresh air filter 100 helps regulate indoor humidity, temperature, and oxygen content by introducing fresh air, thereby improving air circulation efficiency and reducing interference and discomfort to the human body. The fresh air inlet 112 not only introduces fresh outdoor air, but also removes particulate matter and harmful substances from the air through filtration and purification, thus improving indoor air quality.

[0038] In this embodiment, the tray assembly 130 includes a tray component 131 and a fixing component 132. The tray component 131 is embedded in the fresh air inlet 112. The fixing component 132 is detachably connected to the side of the tray component 131 opposite to the housing 110, and the fixing component 132 is located within the receiving cavity 140. The filter component 150 is disposed on the side of the fixing component 132 opposite to the tray component 131. The filter component 150 corresponds to the fresh air inlet 112 and is mounted on the fixing component 132. The tray assembly 130 and the filter component 150 are installed at the position of the fresh air inlet 112. The filter component 150 filters the external air entering the fresh air inlet 112 to ensure air cleanliness. When the filter component 150 needs to be replaced due to dust accumulation, the user can remove the cover 120. The opening 111 of the housing 110 is positioned relative to the fresh air inlet 112. The angled arrangement indicates that the opening direction of the housing 110 and the opening direction of the fresh air inlet 112 form a certain angle, and they are not parallel or collinear. The opening 111 of the housing 110 and the fresh air inlet 112 can be respectively provided on adjacent side surfaces of the housing 110, which facilitates the user to reach into the receiving cavity 140 through the opening 111 to disassemble and separate the tray 131 and the fixing member 132, so as to remove the fixing member 132 and the filter 150, which facilitates the cleaning and replacement of the filter 150, making the operation relatively simple. For example, the opening direction of the opening 111 is perpendicular to the opening direction of the fresh air inlet 112.

[0039] refer to Figure 1 and Figure 2As shown, the fresh air filtration device 100 has a first direction X, a second direction Y, and a third direction Z, wherein the first direction X, the second direction Y, and the third direction Z are arranged perpendicularly to each other. For example, the first direction X refers to the height direction of the fresh air filtration device 100, the second direction Y refers to the width direction of the fresh air filtration device 100, and the third direction Z refers to the length direction of the fresh air filtration device 100. It is understood that the above definitions are only for ease of understanding the relative positional relationships of the various parts in the fresh air filtration device 100 and should not be construed as limitations on this application.

[0040] In one embodiment, reference Figure 3 and Figure 4 As shown, optionally, the tray 131 and the fixing member 132 form a snap-fit ​​structure. Accordingly, the snap-fit ​​structure formed by the tray 131 and the fixing member 132 can make the tray 131 and the fixing member 132 snap together, or the tray 131 and the fixing member 132 can be separated by the snap-fit ​​structure, so as to remove the fixing member 132 and the filter element 150 from the tray 131 and replace and clean the filter element 150.

[0041] Optionally, refer to Figure 5 As shown, the fixing member 132 is provided with a sliding groove 1323, and the corresponding tray member 131 is provided with a sliding rail 1313. The sliding rail 1313 is slidably connected to the sliding groove 1323. When the user moves the fixing member 132, the sliding rail 1313 slides relative to the sliding groove 1323, so that the fixing member 132 and the tray member 131 are separated. In addition, when it is necessary to install the fixing member 132 and the tray member 131, the user pushes the sliding groove 1323 of the fixing member 132 into the sliding rail 1313 of the tray member 131, so that the fixing member 132 and the tray member 131 are connected.

[0042] Combination Figure 2 and Figure 4 As shown, optionally, the tray 131 is provided with a first through hole 1314, and the fixing member 132 is provided with a second through hole 1324. The first through hole 1314, the second through hole 1324, and the fresh air inlet 112 are correspondingly arranged to form a fresh air channel. The fresh air channel is connected to the receiving cavity 140. In other words, the first through hole 1314, the second through hole 1324, and the fresh air inlet 112 are connected. When the tray 131 and the fixing member 132 are installed and connected, it will not affect or obstruct the fresh air exchange function of the fresh air inlet 112. Fresh air enters the receiving cavity 140 through the fresh air channel, which is conducive to air exchange and circulation. The filter 150 is located in the fresh air channel to filter the fresh air entering from the fresh air channel and ensure the cleanliness of the air.

[0043] Optionally, the fixing member 132 is provided with a second slot 1325 of an annular structure on the side opposite to the tray member 131. The filter member 150 can be engaged or disengaged from the second slot 1325, so that the filter member 150 covers the second through hole 1324, thereby filtering and cleaning the air entering and exiting the second through hole 1324 of the fixing member 132. The filter member 150 is installed in the second slot 1325 of the annular structure, which facilitates the installation of the filter member 150 or the removal of the filter member 150 from the second slot 1325.

[0044] For example, filter element 150 can be a dust filter bag with a large dust holding capacity, which can effectively capture particles of different sizes. Alternatively, filter element 150 can also be a filter screen, which is lightweight and easy to install and replace.

[0045] In summary, the fresh air inlet 112 on the housing 110 of the fresh air filtration device 100 is used to introduce fresh outside air. The filter element 150 is installed on the fixing member 132. The tray assembly 130 and the filter element 150 are installed at the position of the fresh air inlet 112. The filter element 150 filters the outside air entering the fresh air inlet 112 to ensure the cleanliness of the air. When the filter element 150 needs to be replaced due to dust accumulation, the user can remove the cover 120. The opening 111 of the housing 110 is set at an angle to the fresh air inlet 112, which allows the user to reach into the receiving cavity 140 through the opening 111 to disassemble and separate the tray assembly 131 and the fixing member 132, so as to remove the fixing member 132 and the filter element 150, which is convenient for cleaning and replacement of the filter element 150. The operation is relatively simple and improves the user experience.

[0046] refer to Figures 1 to 3 As shown, an embodiment of this application provides another fresh air filtration device 100, which includes a housing 110, a cover 120, a tray assembly 130, and a filter element 150.

[0047] Specifically, in combination Figure 2 and Figure 3As shown, the housing 110 is provided with an opening 111 and a fresh air inlet 112. The opening direction of the opening 111 is angled to the opening direction of the fresh air inlet 112. The cover 120 covers the opening 111 and is detachably connected to the housing 110, defining a receiving cavity 140. The tray assembly 130 includes a tray member 131 and a fixing member 132. The tray member 131 is embedded in the fresh air inlet 112, and the fixing member 132 is detachably connected to the side of the tray member 131 opposite to the housing 110, and the fixing member 132 is located within the receiving cavity 140. The filter element 150 is disposed on the side of the fixing member 132 opposite to the tray member 131. The filter element 150 corresponds to the fresh air inlet 112. The fresh air inlet 112 on the housing 110 is used to introduce fresh external air. The filter element 150 is installed on the fixing member 132. The tray assembly 130 and the filter element 150 are installed at the position of the fresh air inlet 112. The filter element 150 filters the external air entering the fresh air inlet 112 to ensure the cleanliness of the air. When the filter element 150 needs to be replaced due to dust accumulation, the user can remove the cover 120. The opening 111 of the housing 110 is set at an angle to the fresh air inlet 112, which allows the user to insert their hand into the receiving cavity 140 through the opening 111 to disassemble and separate the tray member 131 and the fixing member 132, so as to remove the fixing member 132 and the filter element 150, which is convenient for cleaning and replacing the filter element 150. The operation is relatively simple.

[0048] In one embodiment, reference Figure 3 and Figure 4 As shown, optionally, the tray 131 and the fixing member 132 form a snap-fit ​​structure. Accordingly, the snap-fit ​​structure formed by the tray 131 and the fixing member 132 can make the tray 131 and the fixing member 132 snap together, or the tray 131 and the fixing member 132 can be separated by the snap-fit ​​structure, so as to remove the fixing member 132 and the filter element 150 from the tray 131 and replace and clean the filter element 150.

[0049] Furthermore, the tray component 131 is provided with a first buckle 1311 and a second buckle 1312 on the side opposite to the housing 110, and the fixing component 132 is provided with a first slot 1321. The first buckle 1311 is engaged with the first slot 1321, and the end of the fixing component 132 is engaged with the second buckle 1312. In other words, the second buckle 1312 limits the position of the fixing component 132. The first buckle 1311 and the first slot 1321 can engage or disengage, thereby regulating and limiting the fixing component 132 in the first direction X and the third direction Z, so as to realize the assembly and positioning of the tray component 131 and the fixing component 132. This has a certain foolproof function and is used to remind the user that the tray component 131 and the fixing component 132 have been assembled in place.

[0050] As an example, the first buckle 1311 and the second buckle 1312 are respectively located on opposite sides of the fixing member 132. Accordingly, when the tray member 131 and the fixing member 132 are assembled and positioned, the first buckle 1311 and the second buckle 1312 respectively engage and limit the fixing member 132. The fixing member 132 has a plate-like structure, and the first buckle 1311 and the second buckle 1312 are located on opposite sides of the fixing member 132, which has a better engagement and positioning effect.

[0051] In this design, the second latch 1312 is a limiting block, and the first latch 1311 is an elastic protrusion. The elastic protrusion has a certain elasticity so that it can be engaged with the first latch groove 1321, or disengaged from the first latch groove 1321 under external force. The elastic protrusion can be made of plastic, such as ABS plastic, POK material, TPE (thermoplastic elastomer), etc. For example, there are multiple second latches 1312, and any first latch 1311 along the third direction Z is located between two adjacent second latches 1312.

[0052] In one embodiment, alternatively, referencing Figure 3 As shown, a handle 1322 is provided at the end of the fixing member 132 away from the first slot 1321, and the handle 1322 is positioned towards the opening 111. When the handle 1322 is pulled towards the opening 111, the second buckle 1312 separates from the fixing member 132, and the first buckle 1311 separates from the first slot 1321. The handle 1322 is convenient for the user's hand to grip, and the user can move the fixing member 132 through the handle 1322 to separate the fixing member 132 from the tray member 131.

[0053] Further, refer to Figure 4 and Figure 5As shown, the fixing member 132 is provided with a sliding groove 1323, and the corresponding tray member 131 is provided with a sliding rail 1313. The sliding rail 1313 is slidably connected to the sliding groove 1323. When the user moves the fixing member 132, the sliding rail 1313 slides relative to the sliding groove 1323, so that the fixing member 132 and the tray member 131 are separated. In addition, when it is necessary to install the fixing member 132 and the tray member 131, the user pushes the sliding groove 1323 of the fixing member 132 into the sliding rail 1313 of the tray member 131, so that the fixing member 132 and the tray member 131 are connected. For example, the slide groove 1323 has a semi-circular structure, and the corresponding slide rail 1313 has a semi-circular structure. The size and structure of the slide groove 1323 match the size and structure of the slide rail 1313. In addition, the slide groove 1323 forms a semi-enclosed structure so that the slide groove 1323 can cover the slide rail 1313, so that the slide rail 1313 can only disengage from the slide groove 1323 along the first direction X. This avoids the slide rail 1313 from accidentally disengaging or shifting during movement, ensuring the accuracy of operation and thus improving the user experience.

[0054] Optionally, the slide rail 1313 can be moved out of the slide groove 1323 along the first direction X. The opening 111 is oriented in the first direction X, that is, the slide rail 1313 moves out of the slide groove 1323 along the height direction of the fresh air filter device 100, and the opening 111 of the housing 110 is oriented in the height direction of the fresh air filter device 100. After the fixing member 132 is separated from the tray member 131, the opening 111 corresponds to the detachment position of the fixing member 132, so that the fixing member 132 and the filter element 150 can be moved out of the housing 110 through the opening 111 for cleaning and replacement of the filter element 150, which has a better technical effect.

[0055] In one embodiment, combined Figure 2 and Figure 4 As shown, optionally, the tray 131 is provided with a first through hole 1314, and the fixing member 132 is provided with a second through hole 1324. The first through hole 1314, the second through hole 1324, and the fresh air inlet 112 are correspondingly arranged to form a fresh air channel. The fresh air channel is connected to the receiving cavity 140. In other words, the first through hole 1314, the second through hole 1324, and the fresh air inlet 112 are connected. When the tray 131 and the fixing member 132 are installed and connected, it will not affect or obstruct the fresh air exchange function of the fresh air inlet 112. Fresh air enters the receiving cavity 140 through the fresh air channel, which is conducive to air exchange and circulation. The filter 150 is located in the fresh air channel to filter the fresh air entering the fresh air channel and ensure the cleanliness of the air.

[0056] Optionally, the fixing member 132 is provided with a second slot 1325 of an annular structure on the side opposite to the tray member 131. The filter member 150 can be engaged or disengaged from the second slot 1325, so that the filter member 150 is closed in the second through hole 1324, thereby filtering and cleaning the air entering and exiting the second through hole 1324 of the fixing member 132. The filter member 150 is installed in the second slot 1325 of the annular structure, which facilitates the installation of the filter member 150 or the removal of the filter member 150 from the second slot 1325.

[0057] An embodiment of this utility model also provides an air conditioner indoor unit, including the fresh air filter device 100 in the above embodiment. The air conditioner indoor unit including the fresh air filter device 100 has all the beneficial effects of the fresh air filter device 100, which will not be described in detail here.

[0058] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0059] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
