[0035] 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 below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0036] The filter assembly 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings. Figures 1-10 As shown, the filter assembly 100 according to an embodiment of the present invention includes a frame 1, a filter 2 and a filter pressing part 3.

[0037] The frame 1 has a filter housing chamber 11 having an opening 112. A filter 2 is disposed within the filter housing chamber 11. A filter pressing member 3 is movably disposed within the frame 1 between a pressing position and a disengaging position. When the filter pressing member 3 is in the pressing position, the filter 2 is clamped between the filter pressing member 3 and a bottom wall 111 of the filter housing chamber 11. When the filter pressing member 3 is in the disengaging position, the filter pressing member 3 is disengaged from the filter 2. The bottom wall 111 of the filter housing chamber 11 is the wall of the filter housing chamber 11 opposite the opening 112.

[0038] When the filter 2 needs to be installed on the frame 1, the filter pressing piece 3 is first moved to the disengaged position, and then the filter 2 is placed in the filter accommodating cavity 11 through the opening 112. Finally, the filter pressing piece 3 is moved from the disengaged position to the pressing position so that the filter pressing piece 3 presses the filter 2.

[0039] When it is necessary to clean the filter 2, replace the filter 2 with a new one, replace the filter 2 of a different type, etc., first move the filter pressing part 3 from the pressing position to the disengaged position, and then take out the filter 2 from the filter accommodating chamber 11 through the opening 112. Then, the cleaned filter 2 and the new filter 2 can be installed on the frame 1 according to the above process.

[0040] The filter assembly 100 according to the embodiment of the present invention is provided with a filter pressing member 3 that can move between a pressing position and a disengaging position, thereby conveniently and easily pressing and releasing the filter 2, so that the filter 2 can be easily and quickly installed, cleaned, and replaced. Therefore, the filter assembly 100 according to the embodiment of the present invention has the advantages of easy installation of the filter 2, easy cleaning and replacement of the filter 2, and can conveniently and quickly change the filtering function of the filter assembly 100, expand the application range of the filter assembly 100, and better meet the different needs of users.

[0041] like Figures 1-10 As shown, the filter assembly 100 includes a frame 1, a filter 2, and a filter pressing member 3. The frame 1 includes a first frame 13 and a second frame 14, which are detachably connected. Optionally, the first frame 13 and the second frame 14 are detachably connected via a buckle and a slot.

[0042] like Figure 7 and Figure 9 As shown, the first frame body 13 includes a first side portion 134, a third side portion 135, a fourth side portion 136, and a fifth side portion 137. The first side portion 134 and the third side portion 135 are arranged opposite each other in the length direction of the frame body 1, and the fourth side portion 136 and the fifth side portion 137 are arranged opposite each other in the width direction of the frame body 1. The first side portion 134, the fourth side portion 136, the third side portion 135, and the fifth side portion 137 are sequentially connected end to end to define a first cavity 138.

[0043] like Figure 7 and Figure 8 As shown, the second frame 14 includes a second side portion 142, a sixth side portion 143, a seventh side portion 144 and an eighth side portion 145. The second side portion 142 and the sixth side portion 143 are arranged relative to each other in the length direction of the frame 1, and the seventh side portion 144 and the eighth side portion 145 are arranged relative to each other in the width direction of the frame 1. The second side portion 142, the seventh side portion 144, the sixth side portion 143 and the eighth side portion 145 are connected end to end in sequence to define a second cavity 146. When the first frame 13 and the second frame 14 are connected, the first cavity 138 and the second cavity 146 form the filter accommodating chamber 11, that is, the first frame 13 and the second frame 14 define the filter accommodating chamber 11.

[0044] Optionally, the second frame 14 further includes a bottom plate, on which the second side portion 142, the sixth side portion 143, the seventh side portion 144, and the eighth side portion 145 are all disposed. The second side portion 142, the sixth side portion 143, the seventh side portion 144, the eighth side portion 145, and the bottom plate define a second cavity 146. The bottom plate may be provided with an air hole communicating with the filter housing chamber 11, through which air filtered by the filter 2 is discharged. The filter 2 located within the filter housing chamber 11 abuts against the bottom plate, i.e., the bottom plate constitutes the bottom wall surface 111 of the filter housing chamber 11.

[0045] like Figure 7 and Figure 8 As shown, at least two of the second side portion 142, the sixth side portion 143, the seventh side portion 144, and the eighth side portion 145 are provided with flanges 147. The filter 2 located in the filter accommodating cavity 11 abuts against the flanges 147, i.e., the flanges 147 constitute the bottom wall surface 111 of the filter accommodating cavity 11. This makes the structure of the filter assembly 100 more reasonable.

[0046] like Figure 1-Figure 7 、 Figure 9 and Figure 10 As shown, the frame 1 includes a first engaging portion 131, and the filter screen pressing member 3 includes a pressing portion 31 and a second engaging portion 32. When the filter screen pressing member 3 is in the pressing position, the filter screen 2 is clamped between the pressing portion 31 and the bottom wall 111 of the filter screen accommodating chamber 11, and the second engaging portion 32 engages with the first engaging portion 131. When the filter screen pressing member 3 is in the disengaged position, the second engaging portion 32 disengages from the first engaging portion 131, and the pressing portion 31 disengages from the filter screen 2.

[0047] By providing the first clamping portion 131 and the second clamping portion 32, not only can the filter screen pressing piece 3 be more stably in the pressing position so that the filter screen 2 can be more firmly assembled to the filter screen accommodating cavity 11 (frame 1), but also compared with using fasteners, the filter screen pressing piece 3 can be more easily moved from the pressing position to the disengaged position, so that the filter screen 2 can be cleaned, replaced, etc. more easily and quickly.

[0048] Optionally, the first clamping portion 131 may be a buckle, and the second clamping portion 32 may be a buckle or a slot. In addition, the first clamping portion 131 may be a buckle or a slot, and the second clamping portion 32 may be a buckle.

[0049] like Figure 1-Figure 7As shown, the pressing portion 31 is spaced apart from the bottom wall 111 of the filter housing 11 along the thickness direction of the frame 1. The filter pressing member 3 is movable in the frame 1 between a pressing position and a disengaged position along a first direction. The first direction is one of the length and width of the frame 1. This effectively increases the filtration area of the filter 2, thereby effectively improving the throughput of the filter assembly 100 and obtaining more clean air.

[0050] Alternatively, as Figure 6 、 Figure 7 、 Figure 9 and Figure 10 As shown, the pressing portion 31 extends along the second direction, that is, the length direction of the pressing portion 31 is consistent with the second direction, and the second direction is the other of the length direction and the width direction of the frame 1. For example, the first direction can be the length direction of the frame 1 (such as Figure 1 ), the second direction may be the width direction of the frame 1 (as shown by the arrow in Figure 1 As shown by the arrow in FIG). The thickness direction of the frame 1 is as follows Figure 2 As shown by the arrow in .

[0051] There are multiple first engaging portions 131, spaced apart along the second direction. There are multiple second engaging portions 32, spaced apart along the second direction. When the filter screen pressing member 3 is in the pressing position, the multiple second engaging portions 32 engage with the multiple first engaging portions 131 in a one-to-one correspondence. This allows the filter screen pressing member 3 to be more stably positioned in the pressing position, thereby more securely assembling the filter screen 2 into the filter screen accommodating chamber 11 (frame 1).

[0052] like Figure 6 、 Figure 7 and Figure 10 As shown, the filter screen pressing member 3 includes a pressing portion 31, a first mounting arm 34, a second mounting arm 35, and two second clamping portions 32. The first mounting arm 34 and the second mounting arm 35 are provided on the pressing portion 31 at intervals along the second direction. The first mounting arm 34 and the second mounting arm 35 extend from the pressing portion 31 along the first direction toward a direction adjacent to the first clamping portion 131. One second clamping portion 32 is provided on the first mounting arm 34, and the other second clamping portion 32 is provided on the second mounting arm 35.

[0053] The first frame 13 includes two first engaging portions 131, which are located between the first mounting arm 34 and the second mounting arm 35 in the second direction. When the filter screen pressing member 3 is in the pressing position, the two second engaging portions 32 engage with the two first engaging portions 131 in a one-to-one correspondence. This allows the filter screen pressing member 3 to be more stably positioned in the pressing position, thereby more securely assembling the filter screen 2 into the filter screen accommodating chamber 11 (frame 1).

[0054] like Figure 4 、 Figure 5 、 Figure 7 and Figure 10 As shown, the frame 1 includes a support portion 132, which is provided with either a slide groove 33 or a slide rail 133. The pressing portion 31 is provided with the other of the slide groove 33 and the slide rail 133. Both the slide groove 33 and the slide rail 133 extend along a first direction. When the filter pressing member 3 is in the disengaged position, the pressing portion 31 is supported by the support portion 132, and the slide rail 133 fits within the slide groove 33.

[0055] The support portion 132 is provided to support the pressing portion 31 of the filter screen pressing member 3 in the disengaged position, thereby making the filter screen pressing member 3 more stable in the disengaged position. Furthermore, the provision of the slide groove 33 and the slide rail 133 that cooperate with each other makes it easier for the filter screen pressing member 3 to move between the disengaged position and the pressing position.

[0056] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 7 and Figure 8 As shown, the frame 1 includes a limiting portion 141. When the filter screen pressing member 3 is in the pressing position, the pressing portion 31 and the second engaging portion 32 are located between the limiting portion 141 and the first engaging portion 131 in the first direction. The pressing portion 31 and the limiting portion 141 are separated by a predetermined distance in the first direction. This reduces the distance that the filter screen pressing member 3 in the pressing position moves toward the limiting portion 141, thereby making the structure of the filter screen assembly 100 more reasonable.

[0057] For example, the first direction can be a left-right direction, with the pressing portion 31 located to the right of the limiting portion 141, and the second engaging portion 32 located to the right of the pressing portion 31. When the filter screen pressing member 3 is in the pressing position, the first engaging portion 131 is located to the right of the second engaging portion 32. Because the second engaging portion 32 engages with the first engaging portion 131, the first engaging portion 131 can limit the rightward movement of the filter screen pressing member 3. Because the pressing portion 31 and the limiting portion 141 are separated by a predetermined distance in the left-right direction, the limiting portion 141 can limit the leftward movement of the pressing portion 31 (the filter screen pressing member 3). When the filter screen pressing member 3 is in the disengaged position, the pressing portion 31 (the filter screen pressing member 3) is located to the right of the filter screen 2. When the filter screen pressing member 3 is in the pressing position, at least a portion of the pressing portion 31 overlaps with a portion of the filter screen 2 in the left-right direction, allowing the pressing portion 31 to press the filter screen 2.

[0058] like Figure 7 and Figure 8As shown, the frame 1 has a sensor mounting cavity 15, in which a first sensor mounting portion and a second sensor mounting portion are provided. By providing the first and second sensor mounting portions, different types of sensors can be installed on the frame 1 to better cooperate with different types of filters 2, thereby enabling the filter assembly 100 to have different filtering functions and better meet the diverse needs of users.

[0059] For example, when the filter assembly 100 is used in an area with severe haze, an electrostatic filter can be installed on the frame 1 and a PM2.5 sensor (first sensor 200) can be 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 300) can be installed on the second sensor mounting portion.

[0060] like Figure 7 and Figure 8 As shown, the first sensor mounting portion includes a first limiting portion 161, a second limiting portion 162, a third limiting portion 163, a fourth limiting portion 164, a first mounting portion 165, and a second mounting portion 166. The first limiting portion 161 and the second limiting portion 162 are spaced apart along the length of the frame 1, and the third limiting portion 163 and the fourth limiting portion 164 are spaced apart along the width of the frame 1. The first sensor 200 can cooperate with the first limiting portion 161, the second limiting portion 162, the third limiting portion 163, and the fourth limiting portion 164 to limit the first sensor 200 in both the length and width directions of the frame 1, thereby completing the initial installation of the first sensor 200 and facilitating subsequent installation of the first sensor 200.

[0061] Specifically, the first sensor 200 is located between the first limiting portion 161 and the second limiting portion 162 in the longitudinal direction of the frame 1, and the first sensor 200 is adjacent to the first limiting portion 161 and the second limiting portion 162 in the longitudinal direction of the frame 1 or abuts against the first limiting portion 161 and the second limiting portion 162, so that the first sensor 200 can be limited in the longitudinal direction of the frame 1 by using the first limiting portion 161 and the second limiting portion 162.

[0062] The first sensor 200 is located between the third limiting portion 163 and the fourth limiting portion 164 in the width direction of the frame 1. The first sensor 200 is adjacent to the third limiting portion 163 and the fourth limiting portion 164 in the width direction of the frame 1 or abuts against the third limiting portion 163 and the fourth limiting portion 164, so that the third limiting portion 163 and the fourth limiting portion 164 can be used to limit the first sensor 200 in the width direction of the frame 1.

[0063] The first mounting portion 165 and the second mounting portion 166 are spaced apart along the length direction of the frame 1, and are spaced apart along the width direction of the frame 1. The first sensor 200 is connected to each of the first mounting portion 165 and the second mounting portion 166. This allows the first sensor 200 to be more securely mounted.

[0064] Alternatively, as Figure 7 and Figure 8 As shown, the first limiting portion 161 and the third limiting portion 163 are both plate-shaped and connected to form a first L-shaped plate, and the second limiting portion 162 and the fourth limiting portion 164 are both plate-shaped and connected to form a second L-shaped plate. This makes the first sensor mounting portion more reasonable. Each of the first mounting portion 165 and the second mounting portion 166 is a first mounting post 167, and the first mounting post 167 has a threaded hole extending along the thickness direction of the frame 1. In this way, the first sensor 200 can be mounted on the first mounting portion 165 and the second mounting portion 166 using screws, making it more convenient and stable to install the first sensor 200 and more convenient to remove the first sensor 200.

[0065] like Figure 7 and Figure 8 As shown, the second sensor mounting portion includes a fifth limiting portion 171, a sixth limiting portion 172, a seventh limiting portion 173, and a third mounting portion 174. The fifth limiting portion 171 and the sixth limiting portion 172 are spaced apart along one of the length and width directions of the frame 1, and the seventh limiting portion 173 and the third mounting portion 174 are spaced apart along the other of the length and width directions of the frame 1. The second sensor 300 can cooperate with each of the fifth limiting portion 171, the sixth limiting portion 172, and the seventh limiting portion 173 to limit the second sensor 300 in the length and width directions of the frame 1, thereby completing the initial installation of the second sensor 300 and facilitating subsequent installation of the second sensor 300.

[0066] Specifically, the second sensor 300 is located between the fifth limiting part 171 and the sixth limiting part 172 in the length direction (width direction) of the frame 1, and the first sensor 200 is adjacent to the fifth limiting part 171 and the sixth limiting part 172 in the length direction (width direction) of the frame 1 or abuts against the fifth limiting part 171 and the sixth limiting part 172, so that the second sensor 300 can be limited by the fifth limiting part 171 and the sixth limiting part 172 in the length direction (width direction) of the frame 1.

[0067] The second sensor 300 is adjacent to or abuts against the seventh limiting portion 173 in the width direction (length direction) of the frame 1, so that the seventh limiting portion 173 can be used to initially limit the second sensor 300 in the width direction (length direction) of the frame 1. In other words, the width direction (length direction) of the frame 1 includes two unidirectional directions, and the seventh limiting portion 173 can limit the second sensor 300 in one of the unidirectional directions. The second sensor 300 is connected to the third mounting portion 174. This ensures a more stable installation of the second sensor 300.

[0068] Optionally, 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 length and width directions of the frame 1. For example, the first plate segment 1731 and the second plate segment 1732 are spaced apart along the second direction. 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. This can further optimize the second sensor mounting structure.

[0069] The third mounting portion 174 is a second mounting post 175 having a threaded hole extending along the thickness direction of the frame 1. Thus, the second sensor 300 can be mounted on the third mounting portion 174 using a screw, thereby making it more convenient and secure to install the second sensor 300 and to remove it more easily.

[0070] like Figure 7 and Figure 8 As shown, the first side portion 134 and the second side portion 142 define the sensor mounting cavity 15. The second side portion 142 has a mounting surface 1421 opposite to the first side portion 134 in the thickness direction of the frame 1, and the first sensor mounting portion and the second sensor mounting portion are arranged on the mounting surface 1421. In other words, the mounting surface 1421 constitutes a wall surface of the sensor mounting cavity 15. Therefore, when assembling the filter assembly 100, the first sensor 200 can be first installed on the first sensor mounting portion, the second sensor 300 can be installed on the second sensor mounting portion, and then the first frame 13 can be installed on the second frame 14.
