[0024] Please see Figures 1 to 13 This application provides a filter 10 for use in an indoor air conditioning unit.

[0025] This application provides an indoor air conditioning unit, including a frame 20, a panel, and a filter 10 in any embodiment of this application.

[0026] The filter 10 is used to filter the air entering the indoor unit of the air conditioner.

[0027] The indoor unit of an air conditioner can be the indoor part of a split-type air conditioning system or the indoor part of an integrated air conditioning system, where the indoor and outdoor parts of an integrated air conditioning system are integrated into one housing. For example, the indoor unit is a component of a split-type air conditioning system and is used in conjunction with the outdoor unit to regulate indoor temperature and air quality. The filter 10 is used to filter indoor air before it enters the indoor heat exchanger to ensure air quality.

[0028] The filter screen 10 includes a filter screen body 11 and a spring clip 12.

[0029] The filter body 11 is the main structure of the filter 10. The filter body 11 is used to carry the filter material. For example, the face frame 20 has a filter mounting cavity, and the filter body 11 is disposed in the filter mounting cavity.

[0030] The filter body 11 has a first end 111 along a first direction, and the first end 111 has a receiving groove 111a.

[0031] The first direction is the direction in which the filter screen 10 moves when it is installed or removed. For example, the first direction can be the front-back direction or the up-down direction, without limitation. For example, the first direction is the up-down direction.

[0032] The first end 111 is the end side region of the filter body 11 in the first direction, and it is the first to contact the face frame 20 in the first direction when the filter body 11 is installed.

[0033] For example, the first end 111 is the end side region where the short side of the filter body 11 is located.

[0034] The spring clip 12 is disposed in the receiving groove 111a. One end of the spring clip 12 along the first direction is connected to the first end 111, and the other end is a cantilever end 12b. The spring clip 12 has a hook portion 12a, which is used to lock or unlock with the face frame 20 of the air conditioner indoor unit along the first direction under the elastic force of the spring clip 12.

[0035] The spring clip 12 is disposed in the receiving groove 111a, which means that at least a part of the spring clip 12 is located in the space defined by the receiving groove 111a. The spring clip 12 does not need to be completely wrapped by the receiving groove 111a, and the shape of the spring clip 12 does not need to be adapted to the shape of the receiving groove 111a.

[0036] One end of the spring buckle 12 along the first direction is connected to the first end 111, and the other end is a cantilever end 12b. That is, the spring buckle 12 is formed as a cantilever structure. When the spring buckle 12 is subjected to an external force, the cantilever structure spring buckle 12 can move and deform. After the external force is removed, the spring buckle 12 returns to its initial state.

[0037] It should be noted that the elasticity of the spring clip 12 is generated by the cantilever structure of the spring clip 12 itself. The material of the spring clip 12 can be a non-elastic material. For example, the spring clip 12 is integrally formed into the filter screen 10, which makes the structure simpler and has high strength.

[0038] It should be noted that the external force can be the manual operating force applied by the user, or the abutting force between the snap 12 and the face frame 20.

[0039] The first end 111 can provide support for the spring clip 12. The receiving groove 111a can be a through groove or a blind groove, which is not limited here. For example, the receiving groove 111a passes through the first end 111 in a third direction.

[0040] The receiving groove 111a serves several purposes. First, it provides space for the snap-on 12, allowing for its positioning. Second, it provides room for the snap-on 12 to deform under external force. Third, the receiving groove 111a protects the snap-on 12, reducing the chance of accidental activation and damage from scratches or collisions during installation and removal. It also provides clear visual identification of the snap-on 12's position during installation. Finally, the receiving groove 111a also contributes to a neater appearance of the filter screen 10.

[0041] The snap fastener 12 locks into the face frame 20 via a hook portion 12a. The hook portion 12a can be located between the cantilever end 12b of the snap fastener 12 and the end of the snap fastener 12 connected to the first end portion 111.

[0042] For example, during installation, the filter screen 10 is fitted with the face frame 20 along the first direction. The user can apply force to the cantilever end 12b to deform the snap fastener 12 in the receiving groove 111a. The end of the snap fastener 12 away from the cantilever end 12b is inserted into the face frame 20 first. After installation, the force is released, and the snap fastener 12 returns to its original shape, so that the hook 12a hooks the face frame 20, realizing the locking fit between the snap fastener 12 and the face frame 20. In this way, under the elastic force of the snap fastener 12, the face frame 20 and the snap fastener 12 are not easy to separate, and the snap fastener 12 is not easy to detach during the transportation of the indoor unit of the air conditioner.

[0043] Alternatively, during installation, the filter screen 10 is fitted with the face frame 20 along the first direction. The user does not apply force between the cantilever ends 12b, so that the snap fastener 12 is inserted into the face frame 20 along the first direction. When it comes into contact with the face frame 20, the snap fastener 12 is deformed by the contact force with the face frame 20 and can be inserted into the face frame 20 until the hook 12a hooks the face frame 20.

[0044] During disassembly, the user can apply force to the cantilever end 12b to deform the snap 12, thereby engaging the hook 12a and locking it to the face frame 20. This allows the user to easily remove the filter 10 from the face frame 20 for cleaning or replacement. The face frame 20 has an air inlet and a slot 20a. The filter 10 at least covers the air inlet. Part of the snap 12 is inserted into the slot 20a, allowing the hook 12a to be detachably locked in place with the slot 20a. The cantilever end 12b protrudes from the slot 20a, and the panel is mounted on the face frame 20.

[0045] For example, the front frame 20 and the panel are fitted together in the front-to-back direction, which can be one of the following three directions. The panel, as an exterior component of the indoor unit of the air conditioner, is detachably fitted with the front frame 20, and the filter 10 is disposed on the side of the panel facing the front frame 20.

[0046] The slot 20a is used for partial insertion of the snap-on 12 and is detachably locked with the hook 12a to facilitate the installation and removal of the filter screen 10. The cantilever end 12b is exposed outside the slot 20a, meaning that the cantilever end 12b does not enter the slot 20a. When it is necessary to remove it, the user can directly see the cantilever end 12b and apply force to the cantilever end 12b without interference.

[0047] Understandably, in some related technologies, to ensure stable installation and prevent the filter from falling off, overly tight clips are used to secure the filter to the frame. This requires considerable force during installation and removal and can easily damage the connection structure of the frame or filter, making disassembly inconvenient and reducing the user experience. Alternatively, in other related technologies, the structure of the frame or panel is improved to provide sufficient installation and fixation for the filter, but this method increases the structural complexity of the frame or panel.

[0048] The filter 10 provided in this embodiment features a cantilever structure with spring clips 12. During installation, the hook 12a locks onto the frame 20 via its own elasticity, ensuring high installation stability and preventing it from falling off during transport. This simplifies the installation structure of the frame 20 or panel of the indoor unit, resulting in a simpler and more aesthetically pleasing overall structure. Disassembly is easy; applying force to the cantilever end 12b allows the filter 10 to exit the frame 20, enabling convenient removal with one hand without requiring significant force. Furthermore, the inclusion groove 111a reduces the likelihood of damage to the spring clips 12 and enhances the aesthetic appeal of the filter 10.

[0049] It is understood that the number of filters 10 can be one or more; for example, please refer to [link to relevant documentation]. Figure 7 and Figure 13 There are two filters 10, which are arranged in a left-right direction and cooperate with the face frame 20. The left-right direction can be the second direction described below. For example, the filters 10 can be set in the upper region and the front region of the face frame 20, that is, when the filters 10 are installed, the filter body 11 will undergo a moderate bending deformation.

[0050] A single filter 10 can be equipped with one spring clip 12, or multiple spring clips 12 can be provided. For example, please refer to [link to example]. Figure 1 Each filter screen 10 has one spring clip 12.

[0051] In some embodiments, please refer to Figure 1 and Figure 3 The filter screen 10 includes a plug end 13, which is connected to and protrudes from one end of the first end 111 along the first direction. The plug end 13 is used to plug into and cooperate with the face frame 20 of the indoor unit of the air conditioner along the first direction.

[0052] In other words, the plug end 13 and the spring latch 12 are located on the same side of the first end 111 along the first direction. That is, the plug end 13 and the spring latch 12 are not arranged opposite each other along the first direction.

[0053] For example, please refer to Figures 11 to 13 The face frame 20 is provided with a plug slot 20b, and the plug end 13 is inserted into the plug slot 20b.

[0054] In this embodiment, the insertion end 13 serves as a guide and positioning element. When the filter screen 10 is engaged with the face frame 20, the insertion end 13 guides the filter screen 10 to be accurately positioned, facilitating the smooth and stable insertion of the filter screen 10 into the predetermined position and reducing the chance of misalignment or jamming. This facilitates the locking engagement of the snap fastener 12 and the face frame 20, eliminating the need to align the snap fastener 12 with the face frame 20. When the insertion end 13 is inserted into the face frame 20, the snap fastener 12 and the face frame 20 can be locked with a single push. When it is necessary to remove the filter screen 10, only a force needs to be applied to the cantilever end 12b, and then the filter screen 10 can be pulled out. There is no need to operate the insertion end 13, making the operation simple and convenient for users to operate with one hand.

[0055] The fact that the plug-in end 13 and the spring clip 12 are located on the same side makes it easier to increase installation stability and facilitate the cooperation between the spring clip 12 and the plug-in end 13. At the same time, it also allows the face frame 20 to only have a corresponding structure on one side, simplifying the structure of the face frame 20 and reducing costs.

[0056] It should be noted that the plug-in end 13 is used to plug into the face frame 20 to achieve installation guidance. The plug-in end 13 and the face frame 20 do not have a strong locking effect. If there is only the plug-in end, the filter screen is easy to fall out during transportation. Therefore, in this application, the cooperation between the plug-in end 13 and the spring buckle 12, the installation guidance and locking are set separately, reducing the requirements for the spring buckle 12 and increasing the overall structural stability of the filter screen 10.

[0057] In some embodiments, there are multiple plug terminals 13, which are spaced apart along the second direction, and the spring clip 12 is disposed between two adjacent plug terminals 13.

[0058] For example, please refer to Figure 1 and Figure 4 The number of plug-in ends 13 is two, and the two plug-in ends 13 are disposed on opposite sides of the first end 111 along the second direction. The spring buckle 12 is disposed in the middle area of ​​the first end 111 along the second direction.

[0059] In this embodiment, the arrangement of multiple plug-in ends 13 facilitates the formation of guiding constraints, reduces the probability of the filter screen 10 being skewed, and reduces the probability of the filter screen 10 shaking or warping along the second direction during insertion. At the same time, it can also reduce stress concentration. The spring buckle 12 is arranged between two adjacent plug-in ends 13. The spring buckle 12 is arranged close to the middle area to facilitate the protection of the spring buckle 12. At the same time, the spring buckle 12 is positioned by the two plug-in ends 13, so that the spring buckle 12 can cooperate with the face frame 20 without manual alignment.

[0060] In some embodiments, please refer to Figure 3The insertion end 13 has at least one guide rib 131. Along the first direction toward the first end 111, the size of the guide rib 131 gradually increases along the third direction. That is, the guide rib 131 is roughly formed into an inclined extension structure. The further away from the first end 111, the smaller the size of the guide rib 131 along the third direction, making it easier to insert into the face frame 20.

[0061] The first direction, the second direction, and the third direction are all perpendicular to each other. For example, the first direction is the up-down direction, the second direction is the left-right direction, and the third direction is the front-back direction. The up-down, left-right, and front-back directions are the reference directions for the indoor unit of the air conditioner during normal use.

[0062] In this embodiment, the guide rib 131 is provided to facilitate the insertion and engagement of the plug end 13 and the face frame 20, reduce the insertion resistance of the plug end 13, and enable the plug end 13 and the face frame 20 to be inserted and engaged smoothly.

[0063] The number of guide ribs 131 can be one or more; for example, please refer to [reference needed]. Figure 3 There are two guide ribs 131, each protruding from one side of the insertion end 13 along a third direction, and the two guide ribs 131 are spaced apart along a second direction. The arrangement of multiple guide ribs 131 provides local guidance and helps reduce the insertion resistance of the insertion end 13.

[0064] In some embodiments, please refer to Figure 1 , Figure 4 and Figure 5 The filter screen 10 includes a holding part 14, one end of which is connected to the first end 111, and the other end extends protruding along a third direction. The holding part 14 and the snap fastener 12 are arranged side by side and spaced apart along the first direction.

[0065] In this embodiment, the grip 14 is used by the user to hold the filter screen 10, reducing the chance of directly pulling the filter screen body 11, improving operational comfort and safety. The grip 14 and the snap fastener 12 are located on the same side and arranged side by side along the first direction, facilitating simultaneous operation by the user. The user can simultaneously hold the grip 14 and the snap fastener 12 to remove the filter screen 10, and the position of the snap fastener 12 can be determined through the grip 14, further reducing the chance of the user confusing the plug end 13 and the snap fastener 12, and reducing the chance of misoperation. The holding part 14 and the spring buckle 12 are spaced apart along the first direction, which can reduce the probability of mutual interference between the two and increase the structural reliability of the filter screen 10.

[0066] In some embodiments, please refer to Figure 5The extension dimension D1 of the holding part 14 along the second direction is 15mm to 50mm (millimeter), that is, 15mm ≤ D1 ≤ 50mm, for example: 15mm, 20mm, 22mm, 25mm, 28mm, 30mm, 33mm, 35mm, 40mm, 45mm, 48mm, 50mm, etc. For example, the second direction can be the width direction of the filter body 11.

[0067] In this embodiment, the extension dimension of the handle 14 along the second direction is set to ensure sufficient contact area with the user's hand for gripping. At the same time, the extension dimension of the handle 14 along the second direction is not too large, increasing structural simplicity and reducing potential interference with the frame 20 or air intake. Thus, both user operation convenience and the internal structure of the air conditioner indoor unit are taken into account.

[0068] In some embodiments, please refer to Figure 6 The extension dimension D2 of the holding part 14 along the third direction is 15mm~25mm, that is, 15mm≤D2≤25mm, for example: 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, 24mm, 25mm, etc.

[0069] In this embodiment, the grip portion 14 is sized along a third direction to accommodate the user's finger operation space requirements, allowing the user to hook or pinch, thus facilitating comfortable gripping while reducing potential interference with the internal structure of the air conditioner indoor unit, such as the panel.

[0070] In some embodiments, please refer to Figure 2 and Figure 6 The cantilever end 12b extends along a third direction and is arranged parallel to the holding part 14.

[0071] In other words, the cantilever end 12b protrudes from the first end 111 along a third direction, just like the handle 14. In this way, the user can operate the handle 14 and the cantilever end 12b in a unified direction without twisting the wrist or adjusting the posture. The user can operate the cantilever end 12b and the handle 14 simultaneously with one hand to unlock and remove the filter screen 10. For example, by pressing the cantilever end 12b with the thumb and hooking the handle 14 with the other fingers, the user can exert force to unlock the snap 12 from the face frame 20 and operate the handle 14 to remove the filter screen 10, making the operation simpler and more convenient.

[0072] In some embodiments, please refer to Figure 6The distance D3 between the holding part 14 and the cantilever end 12b along the first direction is 7mm~15mm, that is, 7mm≤D3≤15mm, for example: 7mm, 7.5mm, 8mm, 9mm, 10mm, 10.5mm, 11mm, 12mm, 13mm, 14mm, 15mm, etc.

[0073] In this embodiment, the gripping part 14 and the cantilever end 12b are spaced apart along the first direction, which can facilitate the user's grip and application of force while reducing the probability of operational interference.

[0074] In some embodiments, please refer to Figure 5 The extension dimension D4 of the cantilever end 12b along the second direction is 10mm~20mm, that is, 10mm≤D4≤20mm, for example: 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, etc.

[0075] In this embodiment, the extension dimension of the cantilever end 12b along the second direction is designed to facilitate the user to apply force to unlock it, while also providing sufficient strength to reduce the probability of the spring buckle 12 breaking. This ensures that the spring buckle 12 can be used for a long time without plastic deformation, maintains the locking force of the spring buckle 12, and improves the structural reliability of the filter screen 10. Of course, the dimension of the cantilever end 12b along the second direction will not be too large, reducing the space occupied and facilitating the layout with the plug-in end 13.

[0076] In some embodiments, please refer to Figure 6 The distance D5 between the connection point of the spring buckle 12 and the first end 111 and the cantilever end 12b along the first direction is 20mm~30mm, that is, 20mm≤D5≤30mm, for example: 20mm, 21mm, 22mm, 23mm, 24mm, 25mm, 26mm, 27mm, 28mm, 29mm, 30mm, etc.

[0077] The interval between the connection point of the spring buckle 12 and the first end 111 and the cantilever end 12b along the first direction is the interval between the fixed end of the spring buckle 12 and the cantilever end 12b, which represents the effective working length of the spring buckle 12 along the first direction.

[0078] In this embodiment, the fixed end of the spring buckle 12 and the cantilever end 12b are spaced apart along the first direction, which enables the spring buckle 12 to have sufficient rigidity so as to achieve a stable locking engagement with the face frame 20 and reduce the probability of disengagement. At the same time, it also makes it easier for the spring buckle 12 to deform and release from the lock with the face frame 20, reducing the probability of jamming.

[0079] The specific construction of the spring clip 12 is not limited.

[0080] In some embodiments, please refer to Figure 2 , Figure 6 and Figure 10 The snap fastener 12 includes an insertion plate 121 and an abutment plate 122. The first end of the insertion plate 121 is connected to the first end 111, and the second end of the insertion plate 121 is connected to the abutment plate 122. Along the first direction toward the cantilever end 12b, the insertion plate 121 extends obliquely from the connection with the first end 111 toward the direction away from the receiving groove 111a. A hook 12a is formed at the second end of the insertion plate 121. The insertion plate 121 is used to insert into the face frame 20 of the air conditioner indoor unit, and the abutment plate 122 is used to abut against the face frame 20 of the air conditioner indoor unit.

[0081] The first end and the second end of the insertion plate 121 are opposite ends of the insertion plate 121 along the first direction. During assembly, the first end of the insertion plate 121 is first inserted into the slot 20a of the face frame 20 of the air conditioner indoor unit. The hook 12a is formed at the second end of the insertion plate 121. That is, when the second end of the insertion plate 121 is engaged with the slot 20a, the hook 12a will lock and engage with the slot 20a. At this time, the abutment plate 122 abuts against the face frame 20 along the third direction to protect the hook 12a.

[0082] Along the first direction toward the cantilever end 12b, the insertion plate 121 extends at an angle away from the receiving groove 111a. That is, the insertion plate 121 is not a straight cantilever, but a cantilever with an angle. Thus, when the filter screen 10 is pushed into the face frame 20 along the first direction, the insertion plate 121 contacts the face frame 20. Along the third direction, the insertion plate 121 is higher than the slot 20a. That is, at this time, the insertion plate 121 cannot be directly inserted into the slot 20a. Under the abutting force between the insertion plate 121 and the face frame 20, the insertion plate 121 is compressed and deforms along the third direction toward the receiving groove 111a, so that it can be inserted into the slot 20a until the abutting plate 122 abuts against the slot 20a. The insertion plate 121 springs back, and the hook 12a locks into the slot 20a.

[0083] In this embodiment, the insertion plate 121 and the abutment plate 122 provide certain disassembly and assembly guidance, reduce assembly resistance, and facilitate the deformation of the snap fastener 12 due to its contact with the face frame 20 during assembly. This eliminates the need for the user to apply force to the cantilever end 12b, increasing assembly convenience. Furthermore, the contact between the abutment plate 122 and the face frame 20 can limit the position of the face frame 20 and ensure proper assembly, reducing the probability of over-insertion and damage to the hook 12a, and facilitating accurate locking and engagement between the hook 12a and the face frame 20.

[0084] In some embodiments, the abutment plate 122 extends along a first direction. A cantilever end 12b is formed at the end of the abutment plate 122 away from the insertion plate 121 along the first direction. In this embodiment, the cantilever end 12b is formed at the end of the abutment plate 122 away from the insertion plate 121, and both the abutment and unlocking operations are performed on the abutment plate 122, resulting in a simple and compact structure.

[0085] In other embodiments, please refer to Figure 2 and Figure 6 The abutment plate 122 extends in a third direction from one end away from the insertion plate 121 in a first direction to form a cantilever end 12b. In this embodiment, the cantilever end 12b extends in a third direction, and the cantilever end 12b and the abutment plate 122 are approximately "L" shaped. This provides an intuitive and prominent operating position, making it easy for the user to apply force. It is also arranged parallel to the handle 14, so that the user can operate the handle 14 and the cantilever end 12b at the same time, increasing the convenience and comfort of operation.

[0086] In some embodiments, please refer to Figure 6 Along the third direction, the distance D6 between the second end of the insertion plate 121 and the first end of the insertion plate 121 is 2mm to 5mm, that is, 2mm≤D6≤5mm, for example: 2mm, 2.2mm, 2.5mm, 2.7mm, 3mm, 3.3mm, 3.6mm, 4mm, 4.4mm, 4.8mm, 5mm, etc.

[0087] In other words, the dimension of the insertion plate 121 along the third direction is 2mm to 5mm.

[0088] In this embodiment, the size of the insertion plate 121 along the third direction can achieve self-guiding for disassembly and assembly, while also giving the insertion plate 121 sufficient rigidity to reduce the probability of cracking. At the same time, it can also give the insertion plate 121 the necessary elasticity to complete locking or unlocking.

[0089] In some embodiments, please refer to Figure 2 and Figure 6 The insertion plate 121 includes a base plate 1211 and a rib 1212. The base plate 1211 connects the first end 111 and the abutment plate 122. One end of the rib 1212 is connected to the base plate 1211, and the other end extends in a third direction away from the first end 111. At the connection between the base plate 1211 and the abutment plate 122, the rib 1212 protrudes relative to the abutment plate 122 to form a hook portion 12a.

[0090] For example, along a first direction toward the cantilever end 12b, the substrate 1211 extends obliquely away from the receiving groove 111a, and the rib 1212 extends relative to the substrate 1211 along a third direction away from the first end 111. That is, the rib 1212 is a locally thickened structure of the insertion plate 121.

[0091] In this embodiment, the rib 1212 can improve the structural strength of the insertion plate 121. At the same time, the hook 12a formed by the rib 1212 can improve the strength of the hook 12a, thereby reducing the probability of the hook 12a breaking when the filter screen 10 is repeatedly disassembled and reassembled. In addition, it is convenient to set the abutment plate 122 as a flat surface so that it can smoothly abut against the face frame 20.

[0092] In some embodiments, please refer to Figure 2 There are two ribs 1212, and the two ribs 1212 are arranged opposite each other along the second direction.

[0093] For example, two protruding ribs 1212 are disposed on opposite sides of the insertion plate 121 along the second direction.

[0094] In this embodiment, there are two hooks 12a, which facilitates locking with the face frame 20 from multiple points in the second direction, increasing the reliability of locking. At the same time, it can also reduce the mating area between the insertion plate 121 and the face frame 20, reduce the force required for unlocking, and increase the smoothness of unlocking.

[0095] In some embodiments, please refer to Figure 2 and Figure 6 Along the first direction toward the cantilever end 12b, the rib 1212 extends obliquely away from the substrate 1211.

[0096] In this embodiment, the rib 1212 can serve as a guide, thereby facilitating smoother assembly and disassembly, and also facilitating the locking and unlocking of the hook 12a and the face frame 20.

[0097] In some embodiments, please refer to Figure 6 The extension dimension D7 of the rib 1212 along the first direction is not less than 5mm, that is, D7≥5mm, for example: 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, 10mm, etc.

[0098] In this embodiment, the rib 1212 is sized along the first direction, which enables it to have sufficient insertion depth to reliably lock with the face frame 20, while also giving the hook portion 12a sufficient structural strength.

[0099] In some embodiments, please refer to Figure 2The first end portion 111 includes an end wall portion 1111 and an extension portion 1112. The extension portion 1112 is connected to and protrudes from one end of the end wall portion 1111 along a first direction, and together with the end wall portion 1111, forms a receiving groove 111a. The spring buckle 12 is connected to the extension portion 1112 and is spaced apart from the end wall portion 1111 along a second direction.

[0100] The end wall portion 1111 can be the main body base surface of the first end portion 111, that is, the end wall portion 1111 can be the short side edge portion of the filter body 11. The extension portion 1112 protrudes outward from the end wall portion 1111 along the first direction. In this way, the space between the extension portion 1112 and the end wall portion 1111 forms an accommodating groove 111a, eliminating the need for additional drilling. During assembly, the extension portion 1112 drives the spring clip 12 to engage with the slot 20a of the face frame 20.

[0101] For example, please refer to Figure 1 and Figure 2 The plug end 13 is connected to the end wall portion 1111.

[0102] In this embodiment, the end wall portion 1111 and the extension portion 1112 are provided. The extension portion 1112 can serve as a local reinforcing structure to improve the overall structural strength. Furthermore, the spring buckle 12 is connected to the extension portion 1112, and the force generated by the spring buckle 12 is limited to the extension portion 1112 and will not be transmitted to the end wall portion 1111, so as to maintain the overall structural strength and appearance flatness of the filter body 11. At the same time, the extension portion 1112 and the spring buckle 12 cooperate with the face frame 20 together. The extension portion 1112 and the end wall portion 1111 do not affect the deformation of the spring buckle 12. At the same time, they can also improve the overall structural strength of the spring buckle 12 and reduce the probability of damage to the spring buckle 12.

[0103] In some embodiments, please refer to Figure 2 The end wall portion 1111 includes a first bent portion 1111a and a second bent portion 1111b. The first bent portion 1111a and the second bent portion 1111b are disposed opposite to each other along a second direction. The extension portion 1112 is connected to the first bent portion 1111a and the second bent portion 1111b respectively. The space between the first bent portion 1111a and the second bent portion 1111b and the extension portion 1112 together define the receiving groove 111a.

[0104] For example, the holding part 14 is connected to one end of the first bent part 1111a and the second bent part 1111b along the second direction and away from the extension part 1112.

[0105] In this embodiment, the first bending portion 1111a and the second bending portion 1111b can provide sufficient deformation space for the spring buckle 12 while reducing the protrusion size of the filter screen 10 along the first direction, improving the appearance of the filter screen 10, and also facilitating the improvement of the overall structural strength of the filter screen 10.

[0106] In some embodiments, please refer to Figure 2 The first end 111 includes a reinforcing plate 1113, which is disposed in the receiving groove 111a. The reinforcing plate 1113 connects the first bent portion 1111a and the second bent portion 1111b. The reinforcing plate 1113 is spaced apart from the spring buckle 12.

[0107] For example, the reinforcing plate 1113 is connected to the side of the grip 14 facing the spring buckle 12 in the first direction.

[0108] In this embodiment, the reinforcing plate 1113 can connect the first bending part 1111a and the second bending part 1111b, thereby improving the overall structural strength of the filter screen 10. At the same time, it does not affect the deformation of the spring buckle 12, and the overall structural reliability of the filter screen 10 is high.

[0109] For example, in some embodiments, the filter screen 10 is a one-piece structure. That is, the filter screen body 11, the snap fastener 12, and the plug end 13 are all integrally formed, without the need for additional splicing and installation, and the overall structural strength of the filter screen 10 is high.
