[0038] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, and should not be understood as limiting the present invention.

[0039] The filter assembly 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings. Figures 1-9 As shown, the filter assembly 100 according to an embodiment of the present invention comprises a frame 1, a filter 2, a filter pressing part 3 and an air quality sensor.

[0040] The frame 1 has a first side portion 123 and a second side portion 124 that are opposed to each other in a first direction, where the first direction is one of the length and width of the frame 1. A filter 2 is disposed on the frame 1. A filter pressing member 3 is movably disposed on the frame 1 between a pressing position for pressing the filter 2 and a disengaged position for disengaging the filter 2. The filter pressing member 3 is adjacent to the first side portion 123 in the first direction, and an air quality sensor is disposed on the first side portion 123.

[0041] When the filter 2 needs to be installed on the frame 1, first move the filter pressing piece 3 to the disengaged position, then install the filter 2 on the frame 1, and then move the filter pressing piece 3 from the disengaged position to the pressing position so that the filter pressing piece 3 presses the filter 2.

[0042] When the filter 2 needs to be cleaned, replaced with a new one, or replaced with a different type of filter 2, the filter pressing member 3 is first moved from the pressing position to the disengaging position, and the filter 2 is then removed from the frame 1. The cleaned filter 2 and the new filter 2 can then be installed on the frame 1 according to the above process.

[0043] According to the embodiment of the present invention, the filter assembly 100 is provided with a filter pressing part 3 that can move between a pressing position and a disengaging position, so that the filter 2 can be pressed and released conveniently and easily, so that the filter 2 can be easily and quickly installed, cleaned and replaced.

[0044] The filter assembly 100 according to the embodiment of the present invention arranges the air quality sensor on the first side portion 123 and positions the filter pressing member 3 adjacent to the first side portion 123 in the first direction, thereby enabling the filter pressing member 3 and the air quality sensor to be arranged more compactly, thereby effectively reducing the space occupied by the filter pressing member 3 and the air quality sensor on the frame 1. This allows the frame 1 to have more space for installing the filter 2, thereby effectively increasing the filtration area of ​​the filter 2 and thereby effectively improving the flux of the filter 2, thereby obtaining more clean air.

[0045] Therefore, the filter assembly 100 according to the embodiment of the present invention has the advantages of large filtering area, easy installation of the filter 2, easy cleaning and replacement of the filter 2, etc., and can conveniently and quickly change the filtering function of the filter assembly 100, expand the application scope of the filter assembly 100, and better meet the different needs of users.

[0046] like Figures 1-9 As shown, the filter assembly 100 includes a frame 1, a filter 2, and a filter pressing 3. The frame 1 has a first side portion 123 and a second side portion 124 that are opposite to each other along its length, i.e., the first direction is the length of the frame 1. The frame 1 has a filter housing 11, and the filter 2 is disposed within the filter housing 11, thereby making the filter assembly 100 more compact.

[0047] The filter screen pressing member 3 is movably disposed on the frame 1 along the length of the frame 1 between a pressing position for pressing the filter screen 2 and a disengaging position for disengaging the filter screen 2. The filter screen pressing member 3 is adjacent to the first side portion 123 along the length of the frame 1. In other words, when the filter screen pressing member 3 is in the pressing position, the filter screen 2 is clamped between the filter screen pressing member 3 and the frame 1 (the bottom wall of the filter screen accommodating chamber 11).

[0048] Optionally, the first side portion 123 has a sensor mounting cavity 15, and the air quality sensor is disposed in the sensor mounting cavity 15. This not only protects the air quality sensor but also conceals the air quality sensor in the sensor mounting cavity 15, making the filter assembly 100 more compact and aesthetically pleasing.

[0049] Sensor mounting cavity 15 is provided with a first sensor mounting portion and a second sensor mounting portion. The air quality sensor includes a first sensor 4 and a second sensor 5. The first sensor 4 is mounted in the first sensor mounting portion, and the second sensor is mounted in the second sensor mounting portion. This allows different types of sensors to be installed in sensor mounting cavity 15, allowing them to better cooperate with different types of filters 2, thus enabling filter assembly 100 to have different filtering functions and better meet the diverse needs of users.

[0050] Optionally, the first sensor 4 may be a particulate matter sensor (eg, a PM2.5 sensor), and the second sensor 5 may be a TVOC sensor (eg, a formaldehyde sensor).

[0051] For example, when the filter assembly 100 is used in an area with severe haze, an electrostatic filter is installed on the frame 1 and a PM2.5 sensor (first sensor 4) is installed on the first sensor mounting portion; when the filter assembly 100 is used in a newly renovated room, a formaldehyde removal filter can be installed on the frame 1 and a formaldehyde sensor (second sensor 5) can be installed on the second sensor mounting portion.

[0052] The first sensor mounting portion may include a first limiting assembly, a second limiting assembly, and a mounting portion. The first limiting assembly cooperates with the first sensor 4 to limit the position of the first sensor 4 in a first direction. The second limiting assembly cooperates with the first sensor 4 to limit the position of the first sensor 4 in a second direction, the second direction being perpendicular to the first direction. The first sensor 4 is disposed on the mounting portion. This allows the first sensor 4 to be limited in both the first and second directions, thereby completing the initial installation of the first sensor 4 and facilitating subsequent installation of the first sensor 4.

[0053] like Figure 3 and Figure 4As shown, the first limiting assembly includes a first limiting portion 161 and a second limiting portion 162. The first sensor 4 is located between the first limiting portion 161 and the second limiting portion 162 in the first direction, that is, the first limiting portion 161 and the second limiting portion 162 are spaced apart along the first direction. The first sensor 4 is adjacent to or abuts against the first limiting portion 161 in the first direction, and the first sensor 4 is adjacent to or abuts against the second limiting portion 162 in the first direction, so that the first limiting portion 161 and the second limiting portion 162 are used to limit the first sensor 4 in the first direction.

[0054] The second limiting assembly includes a third limiting portion 163 and a fourth limiting portion 164. The first sensor 4 is located between the third limiting portion 163 and the fourth limiting portion 164 in the second direction, that is, the third limiting portion 163 and the fourth limiting portion 164 are spaced apart along the second direction. The first sensor 4 is adjacent to or abuts against the third limiting portion 163 in the second direction, and the first sensor 4 is adjacent to or abuts against the fourth limiting portion 164 in the second direction, so that the third limiting portion 163 and the fourth limiting portion 164 limit the first sensor 4 in the second direction.

[0055] In this way, the first sensor 4 can be better limited in the first direction and the second direction, thereby making it easier to complete the initial installation of the first sensor 4 and facilitating the subsequent installation of the first sensor 4.

[0056] Optionally, the first limiting portion 161 and the second limiting portion 162 are spaced apart along the length direction of the frame 1, and the first sensor 4 is located between the first limiting portion 161 and the second limiting portion 162 in the length direction of the frame 1. The third limiting portion 163 and the fourth limiting portion 164 are spaced apart along the width direction of the frame 1, and the first sensor 4 is located between the third limiting portion 163 and the fourth limiting portion 164 in the width direction of the frame 1. In other words, the first direction can be the length direction of the frame 1 (e.g., Figure 1 ), the second direction may be the width direction of the frame 1 (as shown by the arrow in Figure 1 ).

[0057] like Figure 3 and Figure 4 As shown, the first limiting portion 161 and the third limiting portion 163 are both plate-shaped. The first limiting portion 161 and the third limiting portion 163 are connected to form a first L-shaped plate, and the first corner portion 41 of the first sensor 4 cooperates with the first L-shaped plate. The second limiting portion 162 and the fourth limiting portion 164 are both plate-shaped. The second limiting portion 162 and the fourth limiting portion 164 are connected to form a second L-shaped plate, and the second corner portion 42 of the first sensor 4 cooperates with the second L-shaped plate. The first corner portion 41 and the second corner portion 42 are spaced apart along each of the first direction and the second direction.

[0058] In this way, the first sensor 4 can be more conveniently and easily matched with the first limiting portion 161, the second limiting portion 162, the third limiting portion 163 and the fourth limiting portion 164, thereby making it easier to complete the initial installation of the first sensor 4 and facilitating the subsequent installation of the first sensor 4.

[0059] like Figure 3 and Figure 4 As shown, the mounting portion includes a first mounting portion 165 and a second mounting portion 166. The first mounting portion 165 and the second mounting portion 166 are spaced apart along the first direction, and the first mounting portion 165 and the second mounting portion 166 are spaced apart along the second direction. The first sensor 4 is mounted on each of the first mounting portion 165 and the second mounting portion 166. This allows for a more stable mounting of the first sensor 4.

[0060] Optionally, each of the first mounting portion 165 and the second mounting portion 166 is a first mounting post 167 having a threaded hole extending in the thickness direction of the frame 1. The first sensor 4 is mounted on the first mounting post 167 by a screw member passing through the first mounting post 167 and fitting into the threaded hole. Thus, the first sensor 4 can be mounted on the first mounting portion 165 and the second mounting portion 166 using the screw member, thereby making it more convenient and more stable to mount the first sensor 4 and more convenient to remove the first sensor 4. The thickness direction of the frame 1 is as shown in FIG. Figure 7 As shown by the arrow in .

[0061] like Figure 3 and Figure 4 As shown, the second sensor mounting portion includes a third limiting assembly and a third mounting portion 174. The third limiting assembly cooperates with the second sensor 5 to limit the second sensor 5 in one of the first direction and the second direction. The second sensor 5 is disposed on the third mounting portion 174.

[0062] Thus, the third limiting assembly can be used to limit the second sensor 5 in one of the first direction and the second direction, thereby completing the initial installation of the second sensor 5 and facilitating the subsequent installation of the second sensor 5. Moreover, by arranging the second sensor 5 on the third mounting portion 174, the second sensor 5 can be installed more stably.

[0063] like Figure 3 and Figure 4As shown, the third limiting assembly includes a fifth limiting portion 171 and a sixth limiting portion 172. The second sensor 5 is located between the fifth limiting portion 171 and the sixth limiting portion 172 in one of the first and second directions, that is, the fifth limiting portion 171 and the sixth limiting portion 172 are spaced apart along the one of the first and second directions. The second sensor 5 is adjacent to or abuts against the fifth limiting portion 171 in the one of the first and second directions, and the second sensor 5 is adjacent to or abuts against the sixth limiting portion 172 in the one of the first and second directions.

[0064] Therefore, the fifth limiting portion 171 and the sixth limiting portion 172 can be used to limit the second sensor 5 in one of the first direction and the second direction, so that the second sensor 5 can be better limited in one of the first direction and the second direction, so that the initial installation of the second sensor 5 can be completed more easily and the subsequent installation of the second sensor 5 can be completed.

[0065] like Figure 3 and Figure 4 As shown, the second sensor mounting portion further includes a seventh limiting portion 173. The seventh limiting portion 173 and the third mounting portion 174 are spaced apart along the other of the first direction and the second direction. The second sensor 5 is adjacent to or abuts against the seventh limiting portion 173 in the other of the first direction and the second direction.

[0066] Thus, the seventh limiting portion 173 can be used to limit the second sensor 5 in the other of the first direction and the second direction, thereby better completing the initial installation of the second sensor 5 and further more firmly installing the second sensor 5. In other words, the first direction (the second direction) includes two unidirectional directions, and the seventh limiting portion 173 can limit the second sensor 5 in one of the unidirectional directions.

[0067] like Figure 3 and Figure 4 As shown, the seventh limiting portion 173 includes a first plate segment 1731 and a second plate segment 1732, which are spaced apart along one of the first and second directions. The fifth limiting portion 171 is plate-shaped and connected to the first plate segment 1731 to form a third L-shaped plate. The sixth limiting portion 172 is plate-shaped and connected to the second plate segment 1732 to form a fourth L-shaped plate.

[0068] The first corner portion 51 of the second sensor 5 is engaged with the third L-shaped plate, and the second corner portion 52 of the second sensor 5 is engaged with the fourth L-shaped plate. The first corner portion 51 and the second corner portion 52 are spaced apart along one of the first direction and the second direction. This makes it easier and more convenient for the second sensor 5 to engage with the fifth limit portion 171, the sixth limit portion 172, and the seventh limit portion 173, thereby making it easier to complete the initial installation of the second sensor 5 and facilitating subsequent installation of the second sensor 5.

[0069] Optionally, the fifth limiting portion 171 and the sixth limiting portion 172 are spaced apart along the width direction of the frame 1, and the second sensor 5 is located between the fifth limiting portion 171 and the sixth limiting portion 172 in the width direction of the frame 1. The seventh limiting portion 173 and the third mounting portion 174 are spaced apart along the length direction of the frame 1.

[0070] The third mounting portion 174 is a second mounting post 175. The second mounting post 175 has a threaded hole extending along the thickness of the frame 1. The second sensor 5 is mounted on the second mounting post 175 via a screw threaded through the post and engaging the threaded hole. This allows the second sensor 5 to be mounted on the third mounting portion 174 using the screw thread, making it easier to install and remove the second sensor 5 more securely and conveniently.

[0071] like Figures 1-6 As shown, the frame 1 includes a first frame 13 and a second frame 14. The first frame 13 includes a first sub-side portion 134, and the second frame 14 includes a second sub-side portion 142. The first frame 13 and the second frame 14 are detachably connected, and the first sub-side portion 134 and the second sub-side portion 142 constitute the first side portion 123. The second sub-side portion 142 has a mounting surface 1421 that is opposite to the first sub-side portion 134 in the thickness direction of the frame 1. The first sensor mounting portion and the second sensor mounting portion are provided on the mounting surface 1421.

[0072] In other words, the mounting surface 1421 constitutes a wall of the sensor mounting cavity 15. Therefore, when assembling the filter assembly 100, the first sensor 4 can be mounted to the first sensor mounting portion, the second sensor 5 can be mounted to the second sensor mounting portion, and then the first frame 13 can be mounted to the second frame 14. The filter 2 can then be placed into the filter accommodating cavity 11, and finally the filter pressing member 3 can be moved from the disengaged position to the pressed position.

[0073] Specifically, the first limiting portion 161 , the second limiting portion 162 , the third limiting portion 163 , the fourth limiting portion 164 , the fifth limiting portion 171 , the sixth limiting portion 172 , the seventh limiting portion 173 , the first mounting portion 165 , the second mounting portion 166 and the third mounting portion 174 are all arranged on the mounting surface 1421 .

[0074] Optionally, the first frame 13 has a first vent 1341 in communication with the sensor mounting cavity 15, and the second frame 14 has a second vent 1422 in communication with the sensor mounting cavity 15. This allows indoor air to enter the sensor mounting cavity 15 more smoothly, allowing the first sensor 4 and the second sensor 5 to more accurately measure indoor air parameters (e.g., formaldehyde concentration, PM2.5 concentration), thereby better utilizing the filter assembly 100 to filter the indoor air.

[0075] like Figures 1-6 As shown, there are multiple first vent holes 1341 and multiple second vent holes 1422, and the multiple first vent holes 1341 and the multiple second vent holes 1422 are opposite each other in the thickness direction of the frame 1. This allows indoor air to enter the sensor mounting cavity 15 more smoothly, allowing the first sensor 4 and the second sensor 5 to more accurately measure the parameters of the indoor air, thereby better utilizing the filter assembly 100 to filter the indoor air.

[0076] like Figure 3 and Figure 4 As shown, mounting surface 1421 is further provided with a first boss 168 and a second boss 176. First sensor 4 is supported by first boss 168, first mounting portion 165, and second mounting portion 166, while second sensor 5 is supported by second boss 176 and third mounting portion 174. This prevents first sensor 4 and second sensor 5 from blocking second vent 1422. Optionally, first boss 168, first mounting portion 165, and second mounting portion 166 are substantially equal in size in the thickness direction of frame 1 to facilitate mounting of first sensor 4, and second boss 176 and third mounting portion 174 are substantially equal in size in the thickness direction of frame 1 to facilitate mounting of second sensor 5.

[0077] like Figures 1-9 As shown, the frame 1 includes a first frame 13 and a second frame 14. One of the first frame 13 and the second frame 14 is provided with a latch 131, and the other of the first frame 13 and the second frame 14 is provided with a latch groove 141, and the latch 131 is matched with the latch groove 141. The latch 131 has a first plane 1311, and the wall surface of the latch groove 141 has a second plane 1411, and the first plane 1311 and the second plane 1411 are matched. By making the latch 131 and the latch groove 141 match each other in a planar manner, the latch 131 and the latch groove 141 can be matched more firmly, so that the first frame 13 and the second frame 14 are assembled together more firmly, making the structure of the frame 1 more stable.

[0078] For example, when the filter assembly 100 is disposed at the lower air inlet of the body 400 of the air conditioning device 1000 (e.g. Figure 11As shown), the first plane 1311 is located above the second plane 1411.

[0079] Optionally, the overlapped portion of the first plane 1311 and the second plane 1411 has a dimension of 1.3 mm to 2 mm in the protruding direction of the latch 131. This not only allows the latch 131 and the latch slot 141 to fit more securely, preventing the first frame 13 and the second frame 14 from coming loose, but also prevents the latch 131 and the latch slot 141 from overfitting, allowing the first frame 13 and the second frame 14 to be easily separated when the filter assembly 100 is disassembled for inspection.

[0080] Optionally, the overlapped portion of the first plane 1311 and the second plane 1411 has a dimension of 1.6 mm to 1.8 mm in the protruding direction of the latch 131. This not only allows the latch 131 and the latch slot 141 to fit more securely, preventing the first frame 13 and the second frame 14 from coming loose, but also prevents the latch 131 and the latch slot 141 from overfitting, allowing the first frame 13 and the second frame 14 to be easily separated when the filter assembly 100 is disassembled for inspection.

The latching protrusion 131 on the first sub-side portion 134 protrudes from the first sub-side portion 134 along the length direction (first direction) of the frame 1, i.e., the protruding direction of the latching protrusion 131 is the length direction of the frame 1. The latching protrusion 131 on the fifth sub-side portion 136 (sixth sub-side portion 137) protrudes from the fifth sub-side portion 136 (sixth sub-side portion 137) along the width direction (second direction) of the frame 1, i.e., the protruding direction of the latching protrusion 131 is the width direction of the frame 1.

[0083] The side portion of the second frame body 14 includes a second sub-side portion 142, a fourth sub-side portion 143, a seventh sub-side portion 144, and an eighth sub-side portion 145. The second sub-side portion 142 and the fourth sub-side portion 143 are arranged relative to each other in the length direction of the frame body 1, and the seventh sub-side portion 144 and the eighth sub-side portion 145 are arranged relative to each other in the width direction of the frame body 1. The second sub-side portion 142, the seventh sub-side portion 144, the fourth sub-side portion 143, and the eighth sub-side portion 145 are connected end to end in sequence. The second sub-side portion 142, the seventh sub-side portion 144, and the eighth sub-side portion 145 are all provided with a card slot 141. The fourth sub-side portion 143 is provided with a card protrusion 131, and the card protrusion 131 on the fourth sub-side portion 143 protrudes from the fourth sub-side portion 143 along the length direction (first direction) of the frame body 1, that is, the protruding direction of the card protrusion 131 is the length direction of the frame body 1.

[0084] For example, the protrusion 131 on the first sub-side portion 134 fits into the slot 141 on the second sub-side portion 142, and the protrusion 131 on the fourth sub-side portion 143 fits into the slot 141 on the third sub-side portion 135. The overlapping portion between the first plane 1311 of the protrusion 131 and the second plane 1411 of the slot 141 has a size of 1.3 mm to 2 mm in the length direction of the frame 1.

[0085] The latching protrusion 131 on the fifth sub-side portion 136 (sixth sub-side portion 137) is engaged with the latching groove 141 provided on the seventh sub-side portion 144 (eighth sub-side portion 145), and the overlapping part between the first plane 1311 of the latching protrusion 131 and the second plane 1411 of the latching groove 141 has a dimension of 1.3 mm to 2 mm in the width direction of the frame 1.
