DETAILED DESCRIPTION

[0037] The exemplary embodiments will be described in detail hereinbelow with reference to the drawings. In the following description, the same numbers in different drawings represent the same or similar elements unless otherwise represented. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure. Instead, they only represent examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0038] As shown in FIG. 1, the exemplary embodiments of the present disclosure provide a filter device capable of being applied to an air conditioning apparatus having an air purification function. The air conditioning apparatus includes, but is not limited to, an air conditioner, a ducted-type air conditioner, a fresh air machine, an oxygen generator, and the like. Figures 1 to 8 Specifically, the filter device provided by the present disclosure includes a frame body 1, a filter screen 2, a locking member 3, and a first elastic member 4. The frame body 1 is provided with an accommodating cavity 111. The filter screen 2, which can include a high-efficiency filter screen or the like, is detachably arranged in the accommodating cavity 111. The locking member 3 is slidably arranged on the frame body 1 and has a first position and a second position, wherein: in the first position, the locking member 3 stops the filter screen 2 in a direction of disassembly and assembly of the filter screen 2, and in the second position, the locking member 3 avoids a space for disassembly and assembly of the filter screen 2. The first elastic member 4 is configured to have an elastic force for maintaining the locking member 3 in the first position.

[0039] According to different installation modes of the filter screen 2, the locking member 3 can stop at different parts of the filter screen 2 in the first position, thereby achieving locking of the filter screen 2. Here, the stopping refers to that, in the first position, a projection of the locking member 3 in the direction of the filter screen 2 at least partially overlaps the filter screen 2. Correspondingly, the avoiding of the space for disassembly and assembly of the filter screen 2 refers to that, in the second position, the projection of the locking member 3 in the direction of the filter screen 2 does not overlap the filter screen 2.

[0040] The frame body 1 is usually configured as a rectangle. In the exemplary embodiments, the frame body 1 can be configured as a rectangle, a square, a circle, an oval, or the like.

[0041] Figure 1 ​In the illustrated embodiment, the filter screen 2 is configured to be mounted from the top surface of the frame 1, and the locking member 3 can stop on the upper surface of the filter screen 2 in the first position in a press-fit manner or the like. For example, in the illustration, the locking member 3 is arranged on the side of the frame 1, and in the first position, the locking member 3 stops on the upper surface of the side edge of the filter screen 2. In other embodiments, a socket can also be arranged on the side of the frame 1, and the filter screen 2 can be mounted from the side of the filter screen 2 in a plug-in manner, and the locking member 3 can stop on the side edge of the filter screen 2 in the first position. The amount of press-fit of the locking member 3 in the first position to stop the filter screen 2 can be set according to actual needs, as long as reliable locking of the filter screen 2 can be ensured, for example, the amount of press-fit can range from 1 mm to 2 mm.

[0042] The first elastic member 4 is configured to have an elastic force that maintains the locking member 3 in the first position. When the air conditioning device is normally working, as shown in Figure 2 , under the action of the first elastic member 4, the locking member 3 can always stop the filter screen 2, so that the filter screen 2 cannot be removed, ensuring the reliability of the locking of the filter screen 2. When it is necessary to remove the filter screen 2, as shown in Figure 3 , the user only needs to manually drive the locking member 3 to the second position against the elastic force of the first elastic member 4, at which time the locking member 3 avoids the space for disassembly. In order to facilitate the operation of the locking member 3, as shown in Figure 4 , a tab 311 can be arranged on the locking member 3 for manipulating the locking member 3 in a direction against the elastic force of the first elastic member 4.

[0043] Considering that the filter screen 2 is a component that needs to be frequently cleaned or replaced, whether it can be conveniently and efficiently disassembled is more intuitive in terms of user experience. The filter device provided by the present disclosure has a relatively simple structure through the cooperation of the locking member 3 and the first elastic member 4, reliable locking is achieved through the first elastic member 4, and unlocking can be achieved through simple manual operation, the entire locking and unlocking process is convenient and efficient, which helps to improve the competitiveness of the product.

[0044] As one embodiment for realizing that the locking member 3 can slide to lock and unlock the filter screen 2, reference is made to Figure 4 and Figure 5, the locking member 3 can include a locking portion 31 for stopping the filter screen 2 and a sliding portion 32 slidably connected with the frame 1 and capable of driving the locking portion 31 to slide. The locking portion 31 and the sliding portion 32 can be configured as an integral piece or can be configured as separate pieces that can be mounted together. The frame 1 is provided with a first stop portion 112, and the first elastic member 4 is elastically abutted between the sliding portion 32 and the first stop portion 112. The first stop portion 112 can be configured as a baffle integrally formed on the frame 1, for example, to limit the first elastic member 4. After the locking member 3 is mounted on the frame 1, the first elastic member 4 is in a compressed state, and because one end of the first elastic member 4 is stopped by the first stop portion 112, an elastic thrust force is formed on the other end of the first elastic member 4 to push the sliding portion 32, so that the locking portion 31 can be maintained in the first position.

[0045] In order to ensure that the locking member 3 can slide along a predetermined track, in some embodiments, one of the sliding portion 32 and the frame 1 is provided with a sliding rail 113, and the other is provided with a sliding groove 321 that slidably cooperates with the sliding rail 113. In the embodiment shown in the drawings, Figure 4 and Figure 5 In the embodiment shown in the drawings, the sliding rail 113 is provided on the frame 1, and the sliding groove 321 is provided on the sliding portion 32. The sliding rail 113 can be configured as a rib plate extending in the sliding direction. The sliding rail 113 and the sliding groove 321 are cooperated in this way, which can improve the stability of the locking member 3 during sliding.

[0046] Further, the sliding portion 32 is provided with a guide column 33, the first elastic member 4 is a spring and is sleeved on the guide column 33, the first stop portion 112 is provided with a notch 1121, and the guide column 33 is slidably arranged in the notch 1121. The outer circumferential surface of the guide column 33 can be provided with a protruding rib for clamping cooperation with the first elastic member 4, to avoid the first elastic member 4 from being separated from the sliding portion 32 during sliding of the sliding portion 32. The notch 1121 is used to provide support for the guide column 33 to slide thereon and can provide a sliding guide function. Among them, Figure 6 shows the state of the locking member 3 and the first elastic member 4 in the first position (sliding to the left in the drawing) to lock the filter screen 2, Figure 7 shows the state of the locking member 3 and the first elastic member 4 in the second position (sliding to the right in the drawing) to unlock the filter screen 2.

[0047] As Figure 1As shown, the frame 1 comprises a lower cover 12 and an upper cover 11 detachably covering the top of the lower cover 12. In some filter devices, in addition to comprising the filter screen 2, electronic devices such as sensors for detecting air quality can also be included. In order to facilitate the installation and maintenance of these electronic devices, the frame 1 can be configured in a split structure, wherein the upper cover 11 can cover the lower cover 12 and form a box body accommodating the electronic devices near the side of the accommodating cavity 111. Referring to Figure 4 and Figure 5 , the slide rail 113 can be provided on the upper cover 11, and the slide groove 321 can be provided on the sliding part 32. Considering the fitting gap between the upper cover 11 and the lower cover 12, the width of the slide groove 321 can range from 2.5㎜ to 3㎜, and / or the width of the slide rail 113 can range from 0.8㎜ to 1㎜.

[0048] In some embodiments, as shown in Figure 1 , the lower cover 12 can be provided with a second stop portion 121 for abutting with the end of the sliding part 32 to limit the displacement amount of the sliding part 32 when in the first position. By limiting the displacement amount of the sliding part 32 in the first position through the second stop portion 121, the sliding part 32 can be prevented from being pulled out of the slide rail 113 under the elastic force of the first elastic member 4 and the inertial force of the sliding of the sliding part 32. The locking member 3 and the first elastic member 4 can be installed on the upper cover 11 first, and then the upper cover 11 is covered on the lower cover 12, and the second stop portion 121 on the lower cover 12 can achieve the limiting effect on the sliding part 32. It should be understood that the position of the second stop portion 121 can be set according to actual needs, for example, the second stop portion 121 can also be provided on the upper cover 12.

[0049] In other embodiments, since the locking member 3 and the first elastic member 4 need to be installed on the upper cover 11 first, this results in that during the subsequent process of covering the upper cover 11 on the lower cover 12, the spring will always have an elastic pushing force on the sliding part 32, making it difficult to position the sliding part 32. Considering this technical problem, as shown in Figure 5 , a third stop portion 1131 can be protrudingly provided on the slide rail 113, and the third stop portion 1131 is used for abutting with the end of the sliding part 32 to limit the position of the sliding part 32 during installation. That is, the sliding part 32 can be pre-positioned by the third stop portion 1131, and when the upper cover 11 is installed on the lower cover 12, the sliding part 32 will not move due to the elastic force. After the upper cover 11 and the lower cover 12 are covered, the displacement amount of the sliding part 32 can be limited by the second stop portion 121.

[0050] As shown in Figures 2 to 4As shown, the locking portion 31 is configured in a strip shape and accommodated in the accommodating cavity 111, and the sliding portions 32 are two and arranged on both sides of the extension direction of the locking portion 31. Among them, the strip-shaped locking portion 31 increases the stopping area of the filter screen 2, and improves the reliability of locking the filter screen 2, and by arranging the sliding portions 32 on both ends of the locking portion 31, the stability of the sliding of the locking member 3 is improved.

[0051] The filter screen 2 can be provided with a handle for taking out, which can be a flexible belt, for example, and / or as Figure 8 As shown, a second elastic member 5 can be arranged between the bottom of the filter screen 2 and the frame 1, which can be a spring, used to pop out the filter screen 2 from the accommodating cavity 111 after the locking member 3 releases the locking of the filter screen 2. For example, when the locking member 3 is in the first position and locks the filter screen 2, the filter screen 2 will not be popped out even under the action of the second elastic member 5, and when the locking member 3 is in the second position and unlocks the filter screen 2, according to the different arrangement positions of the second elastic member 5, the filter screen 2 close to the side of the locking member 3 can be at least popped out, and then the filter screen 2 is completely taken out by pulling the handle.

[0052] According to the second aspect of the embodiments of the present disclosure, an air conditioning device is also provided, which comprises the filter device of any one of the above and has all the beneficial effects thereof, which will not be repeated here.
