[0046] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0047] like Figure 1-Figure 14 As shown, an embodiment of the present application provides a filter assembly 100, which can be used in an air treatment device.

[0048] like Figure 3-Figure 14 As shown, the filter assembly 100 includes a mounting bracket 1 and a filter screen 2, the filter screen 2 is mounted to the mounting bracket 1, and one end of the filter screen 2 is movably connected to the mounting bracket 1 so that the filter screen 2 can be in a filtering state (such as Figure 4-Figure 7 as shown) and cleaning status (as shown Figure 8-Figure 11 to switch between the two modes.

[0049] The filter screen is provided with a hand-grip position, and the filter screen is configured to switch the filter screen from the filtering state to the cleaning state by applying force on the hand-grip position. The filter screen 2 is provided with a hand-grip position, and the filter screen 2 is configured to switch the filter screen from the filtering state (such as Figure 4-Figure 7 Switch to the cleaning state (as shown) Figure 8-Figure 11 shown).

[0050] In the filter assembly 100, one end of the filter screen 2 is movably connected to the mounting bracket 1, so that the filter screen 2 can move relative to the mounting bracket 1, so that the filter screen 2 moves to a filtering state or a cleaning state; the filter screen 2 is provided with a handle position, and the user (or other operator) can drive the filter screen 2 to move by applying force to the handle position, so that the filter screen 2 can be switched from the filtering state to the cleaning state. The filter screen 2 can be switched from the cleaning state to the filtering state by applying force to the handle position to drive the filter screen 2 to move, or by applying force to other parts of the filter screen 2 to drive the filter screen 2 to move.

[0051] When the filter screen 2 is in the filtering state, the filter assembly 100 can realize the filtering function; when the filter screen 2 is in the cleaning state, it is convenient to clean the filter screen 2 to remove dirt on the filter screen 2.

[0052] The embodiment of the present application provides an easy-to-clean filter assembly 100, which is user-centric and drives the filter 2 to move by means of a hand-locking position, so that the user's hands will not be dirty when the filter 2 is disassembled and washed; and compared to the filter 2 assembled by means of an interference fit on all sides, the disassembly and washability structure of the filter 2 in the embodiment of the present application is very simple, thereby reducing the time required for cleaning and replacing the filter 2.

[0053] In some exemplary embodiments, the mounting bracket 1 is provided with a mounting cavity 11 , and the filter screen 2 is configured to be accommodated in the mounting cavity 11 when in a filtering state, and the other end of the filter screen 2 is moved out of the mounting cavity 11 when in a cleaning state.

[0054] The mounting bracket 1 is provided with a mounting cavity 11, and the filter 2 can be accommodated in the mounting cavity 11 when it is in the filtering state, so that the mounting bracket 1 can firmly support the filter 2, ensuring that the filter 2 realizes the filtering function; when the filter 2 is in the cleaning state, the other end of the filter 2 moves to the outside of the mounting cavity 11, so that the main part of the filter 2 is located outside the mounting cavity 11, so that the filter 2 can be cleaned and dried, ensuring the cleaning effect of the filter 2.

[0055] In some exemplary embodiments, one of the inner wall surface of the mounting cavity 11 and the outer wall surface of the filter 2 is provided with a slide groove 113, and the other is provided with a sliding portion 22, and the sliding portion 22 is configured to be able to slide and rotate in the slide groove 113 so that the filter 2 can be flipped relative to the mounting bracket 1 to switch between the filtering state and the cleaning state.

[0056] like Figure 5 , Figure 12-14 As shown, the two opposite inner side walls of the installation cavity 11 are provided with a slide groove 113, and the two opposite outer side walls of the filter screen 2 are provided with a sliding portion 22. The sliding portion 22 can be a cylindrical protrusion arranged at the end of the two opposite outer side walls of the filter screen 2. The sliding portion 22 can extend into the slide groove 113, and the sliding portion 22 can slide and rotate in the slide groove 113, so that the filter screen 2 can be turned over, so that the filter screen 2 can be switched between the filtering state and the cleaning state. When the filter screen 2 is in the filtering state, it can be moved along the Figure 7 Flip in the direction indicated by the middle arrow D1 to switch to the cleaning state; when the filter screen 2 is in the cleaning state, it can be turned along Fig.10 The direction indicated by the middle arrow D2 is flipped to switch to the filtering state.

[0057] In the filter assembly 100, the filter 2 can both slide and rotate. Compared with the solution in which the filter 2 can only rotate, the filter assembly 100 of the embodiment of the present application has an installation cavity 11 that takes into account both accommodating the filter 2 and not interfering with the movement of the filter 2, and the volume of the installation cavity 11 is relatively small, which is beneficial to reducing the overall size of the filter assembly 100.

[0058] In some exemplary embodiments, Figure 5 As shown, the slide groove 113 includes a first groove section 114 and a second groove section 115, the extension direction of the first groove section 114 is perpendicular to the depth direction of the installation cavity 11, one end of the second groove section 115 is connected to one end of the first groove section 114, and the other end of the second groove section 115 extends toward the side where the opening of the installation cavity 11 is located. The extension direction of the second groove section 115 is parallel to the depth direction of the installation cavity 11.

[0059] The slide groove 113 includes a first groove section 114 and a second groove section 115. The extension direction of the first groove section 114 can be perpendicular to the depth direction of the installation cavity 11. The sliding part 22 of the filter 2 slides along the first groove section 114 and rotates in the first groove section 114. The volume of the installation cavity 11 can be reduced while the installation cavity 11 can accommodate the filter 2 and not interfere with the movement of the filter 2.

[0060] One end of the second slot section 115 is connected to one end of the first slot section 114, and the other end of the second slot section 115 extends toward the side where the opening of the installation cavity 11 is located, so that the extension direction of the second slot section 115 can be parallel to the depth direction of the installation cavity 11. The arrangement of the second slot section 115 ensures that when the filter screen 2 is accommodated in the installation cavity 11, the filter screen 2 will not protrude from the installation cavity 11 or the height of the filter screen 2 protruding from the installation cavity 11 is reduced, which is conducive to reducing the depth dimension of the installation cavity 11.

[0061] The filter screen 2 is in a filtering state accommodated in the installation cavity 11 (eg Figure 4 ), the sliding portion 22 of the filter screen 2 may be located in the second slot section 115 of the chute 113. When the filter screen 2 needs to be cleaned and switched from the filtering state to the cleaning state, the sliding portion 22 of the filter screen 2 may enter the first slot section 114 of the chute 113 from the second slot section 115 of the chute 113, and move in the first slot section 114 in a direction away from the second slot section 115; the sliding portion 22 of the filter screen 2 slides and rotates simultaneously in the process of entering the first slot section 114 from the second slot section 115, so that the filter screen 2 is turned over, so that the filter screen 2 is switched to the cleaning state (as shown in FIG. 1 ). Figure 8-Figure 11 The arrangement of the first slot section 114 and the second slot section 115 realizes the change of the motion track of the sliding portion 22 of the filter screen 2, so that the filter screen 2 can be switched between the filtering state and the cleaning state.

[0062] Since the extension direction of the second slot section 115 of the chute 113 is perpendicular to the extension direction of the first slot section 114, the angle between the filter screen 2 and the mounting bracket 1 can be 90° (eg, Fig.10 As shown), the filter screen 2 can be directly rinsed and aired. During cleaning and airing, the free ends of the filter screen 2 and the mounting bracket 1 can be supported and fixed to form a triangular stable shape to prevent the filter assembly 100 from deforming during cleaning and airing.

[0063] Of course, the extension direction of the second groove section 115 of the slide groove 113 may not be set to be perpendicular to the extension direction of the first groove section 114 (that is, the extension direction of the second groove section 115 may not be parallel to the depth direction of the installation cavity 11, but may be at a certain angle (such as: the angle may be greater than 90°)). In this case, when in the cleaning state, the angle between the filter 2 and the installation bracket 1 may be non-90° (such as: the angle may be greater than 90°).

[0064] When the filter screen 2 is cleaned and switched from the cleaning state to the filtering state, the sliding portion 22 of the filter screen 2 can enter the second slot section 115 of the slide 113 from the first slot section 114 of the slide 113, and the sliding portion 22 of the filter screen 2 slides and rotates simultaneously in the process of entering the second slot section 115 from the first slot section 114, so that the filter screen 2 is flipped so that the filter screen 2 can switch to the filtering state.

[0065] In some exemplary embodiments, Figure 4 and Figure 8 As shown, the mounting bracket 1 is provided with a support portion 116, the support portion 116 is close to the end of the first slot section 114 that is connected to the second slot section 115, and the filter screen 2 is configured to be supported on the support portion 116 when in a cleaning state (such as Figure 8 shown).

[0066] The mounting bracket 1 is provided with a supporting portion 116 , which can support the filter screen 2 when the filter screen 2 is in a cleaning state, so that the filter screen 2 can be stably maintained in the cleaning state, so as to facilitate cleaning of the filter screen 2 .

[0067] In some exemplary embodiments, Figure 8 As shown, the installation cavity 11 includes a first cavity wall 111 and a second cavity wall 112 that are arranged opposite to each other. The length directions of the first cavity wall 111 and the second cavity wall 112 are parallel to the extension direction of the first groove section 114 , and the support portion 116 is connected between the first cavity wall 111 and the second cavity wall 112 .

[0068] The length directions of the relatively arranged first cavity wall 111 and the second cavity wall 112 of the installation cavity 11 are parallel to the extension direction of the first groove section 114. The slide groove 113 can be arranged on the first cavity wall 111 and the second cavity wall 112. The support part 116 is connected between the first cavity wall 111 and the second cavity wall 112 so as to support the filter screen 2 in a cleaning state. Due to the arrangement of the slide groove 113, the support part 116 will not interfere with the movement of the filter screen 2.

[0069] In some exemplary embodiments, Figure 4 , Figure 6-Figure 8 As shown, the handle position includes a first handle position 211 and / or a second handle position 212 (that is, includes at least one of the first handle position 211 and the second handle position 212), the first handle position 211 is arranged on the first side wall 27 of the filter 2 opposite to the first cavity wall 111, and the first cavity wall 111 is provided with a first avoidance groove 117 matched with the first handle position 211; the second handle position 212 can be arranged on the second side wall 28 of the filter 2 opposite to the second cavity wall 112, and the second cavity wall 112 is provided with a second avoidance groove 118 matched with the second handle position 212.

[0070] The first side wall 27 of the filter 2 (opposite to the first cavity wall 111 of the installation cavity 11) is provided with a first handle position 211, and the first cavity wall 111 of the installation cavity 11 is provided with a first avoidance groove 117, and the first handle position 211 can be a convex structure, which can protrude from the first avoidance groove 117, so that the user can apply force to the first handle position 211; the second side wall 28 of the filter 2 (opposite to the second cavity wall 112 of the installation cavity 11) is provided with a second handle position 212, and the second cavity wall 112 of the installation cavity 11 is provided with a second avoidance groove 118, and the second handle position 212 can be a convex structure, which can protrude from the second avoidance groove 118, so that the user can apply force to the second handle position 212. The first handle position 211 and the second handle position 212 cooperate to facilitate the user's operation and facilitate the user to flip the filter 2.

[0071] Of course, the first handle position 211 and the second handle position 212 are not limited to being protruding structures. For example, the first handle position 211 and the second handle position 212 can be formed by using the outer wall of the first side wall 27 and the second side wall 28 of the filter screen 2. In this case, force can be applied to the first handle position 211 and the second handle position 212 through the first avoidance groove 117 and the second avoidance groove 118. The first handle position 211 and the second handle position 212 can be set at the same time, or only the first handle position 211 or the second handle position 212 can be set.

[0072] In some exemplary embodiments, the handle is provided with an anti-slip structure to increase friction and prevent slippage when force is applied to the handle. Figure 6 and Figure 7 As shown, the anti-slip structure can be a protrusion or a groove provided on the first hand-engaging position 211 and the second hand-engaging position 212 .

[0073] In some exemplary embodiments, Figure 4 As shown, the mounting cavity 11 is arranged along its length direction (such as Figure 4 The installation cavity 11 is arranged along its width direction (such as Figure 4 The direction indicated by the arrow W in the middle) has an interference fit with the filter screen 2 in the filtering state.

[0074] Along the length direction of the installation cavity 11, the installation cavity 11 can be interference-fitted with the filter screen 2 (in the filtering state) accommodated in the installation cavity 11; along the width direction of the installation cavity 11, the installation cavity 11 can be interference-fitted with the filter screen 2 (in the filtering state) accommodated in the installation cavity 11. Through the interference fit between the installation cavity 11 and the filter screen 2 therein, and the fit between the slide groove 113 of the installation cavity 11 and the sliding part 22 of the filter screen 2, the filter screen 2 can be stably maintained in the installation cavity 11, so that the filter screen 2 in the filtering state can achieve the filtering function.

[0075] Due to the cooperation between the slide groove 113 of the installation cavity 11 and the sliding portion 22 of the filter screen 2, the installation cavity 11 and the filter screen 2 accommodated in the installation cavity 11 are only interference-fitted in the length or width direction of the installation cavity 11, so that the filter screen 2 can be stably maintained in the installation cavity 11. In the case where the installation cavity 11 and the filter screen 2 accommodated in the installation cavity 11 are interference-fitted in both the length and width directions of the installation cavity 11, the filter screen 2 can be conveniently switched between the filtering state and the cleaning state by providing the buckle position.

[0076] In some exemplary embodiments, the filter 2 may be a filter 2 that utilizes electrostatic dust removal, such as a HEPA filter.

[0077] In some exemplary embodiments, Figure 4 , Figure 7-Figure 13 As shown, the filter screen 2 is provided with a first electrode portion 23 and a second electrode portion 24 , and the mounting bracket 1 is provided with a switch matching portion 12 .

[0078] Among them, Figure 2 As shown, the filter assembly 100 is configured so that when installed in the air duct 500 of the air treatment device, the first electrode portion 23 and the second electrode portion 24 can be electrically connected to the first power supply circuit of the air treatment device, and the switch matching portion 12 can match with the forced switch 300 in the first power supply circuit to put the forced switch 300 in a connected state.

[0079] The filter assembly 100 is configured so that after being removed from the air duct 500 of the air treatment device, the first electrode portion 23 and the second electrode portion 24 can be electrically disconnected from the first power supply circuit, and the switch matching portion 12 can be disconnected from the forced switch 300, so that the forced switch 300 is in a non-connected state.

[0080] like Figure 2 As shown, when the filter assembly 100 (filter screen 2 is in filtering state) is installed in the air duct 500 of the air handling device, the first electrode portion 23 and the second electrode portion 24 on the filter screen 2 can be electrically connected to the two connection contacts of the first power supply circuit of the air handling device, and the switch matching portion 12 on the mounting bracket 1 can match with the forced switch 300 in the first power supply circuit (e.g., the switch matching portion 12 can abut against the forced switch 300), so that the forced switch 300 is switched to the connected state. At this time, the filter screen 2 is powered on, and the electrostatic dust removal effect can be achieved.

[0081] After the filter assembly 100 is removed from the air duct 500 of the air handling device, the first electrode portion 23 and the second electrode portion 24 on the filter screen 2 can be electrically disconnected from the two connection contacts of the first power supply circuit of the air handling device, and the switch matching portion 12 on the mounting bracket 1 is disconnected from the forced switch 300 (e.g., the switch matching portion 12 is disconnected from the forced switch 300), so that the forced switch 300 automatically returns to a non-connected state (disconnected state). At this time, the filter screen 2 of the removed filter assembly 100 can be cleaned, and because the forced switch 300 is in a non-connected state, the risk of electric shock when a person touches the two connection contacts of the first power supply circuit at the same time can be avoided.

[0082] In some exemplary embodiments, the first electrode portion 23 and the second electrode portion 24 may be made of metal material or other conductive materials. Figure 7-Figure 13 As shown, the first electrode portion 23 and the second electrode portion 24 can be arranged on the first side wall 27 of the filter 2, and the first cavity wall 111 of the mounting cavity 11 of the mounting bracket 1 is provided with a third avoidance groove 119 and a fourth avoidance groove 1110 to avoid the first electrode portion 23 and the second electrode portion 24 respectively, so that the first electrode portion 23 and the second electrode portion 24 can be electrically connected to the two connection contacts of the first power supply circuit.

[0083] like Figure 2 As shown, the two connection contacts of the first power supply circuit can be formed by using the first metal contact sheet 201 and the second metal contact sheet 202 respectively.

[0084] In some exemplary embodiments, Figure 4-Figure 10 As shown, the mounting bracket 1 is provided with at least one snap buckle 14 protruding outward, and the snap buckle 14 is configured to snap-fit ​​with the air duct wall of the air handling device. Figure 2 As shown, a snap button 14 forms the switch matching portion 12 and can be matched with the forced switch 300 .

[0085] The mounting bracket 1 of the filter assembly 100 is provided with at least one (e.g., two or other number) spring buckles 14 protruding outwardly. On the one hand, when the filter assembly 100 is installed in the air duct 500 of the air handling device, the spring buckles 14 can be snap-fitted with the air duct wall to fix the filter assembly 100 in the air duct 500; on the other hand, one of the spring buckles 14 can be used as a switch matching portion 12. After the filter assembly 100 is installed in the air duct 500 of the air handling device, the spring buckle 14 can abut against the forced switch 300 in the first power supply circuit (e.g., Figure 2 As shown), the forced switch 300 is switched to the connected state to supply power to the filter 2.
