DETAILED DESCRIPTION

[0038] The exemplary embodiments will be described in detail herein with reference to the accompanying drawings. In the following description, unless otherwise indicated, like numbers in the different drawings represent similar or analogous elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure. Instead, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0039] As Figures 1 to 10 shown, the exemplary embodiments of the present disclosure provide a filter device which can be applied to air conditioning equipment with air purification function. The air conditioning equipment includes, but is not limited to, air conditioners, ducted air conditioners, fresh air machines, oxygen machines, etc.

[0040] Specifically, the filter device provided by the present disclosure includes a frame 1, a filter screen 2, and a presser 3. The frame 1 is provided with an accommodating cavity 111. The filter screen 2, which may, for example, include a high-efficiency filter screen, is detachably arranged in the accommodating cavity 111. The presser 3 includes a pressing part 31 and a cantilever part 32. The pressing part 31 has a first position when not pressed and a second position after being pressed. The free end of the cantilever part 32 can swing under the driving of the pressing part 31. In the first position, the free end of the cantilever part 32 stops the filter screen 2 in the dismounting direction of the filter screen 2. In the second position, the free end of the cantilever part 32 is inclined to avoid the space for dismounting the filter screen 2. The pressing part 31 and the cantilever part 32 can be configured as an integrated structure or a split structure.

[0041] According to different installation manners of the filter screen 2, the free end of the cantilever part 32 can be stopped at different positions of the filter screen 2 in the first position, thereby achieving locking of the filter screen 2. Here, stopping refers to that, in the first position, the projection of the free end of the cantilever part 32 in the direction of the filter screen 2 at least partially overlaps the filter screen 2. Correspondingly, the space for dismounting the filter screen 2 refers to that, in the second position, the projection of the free end of the cantilever part 32 in the direction of the filter screen 2 does not overlap the filter screen 2.

[0042] The frame 1 is generally configured as a rectangle. In Figure 1 In the illustrated embodiment, the filter screen 2 is configured to be installed from the top surface of the frame 1, and the free end of the cantilever part 32 can be stopped on the upper surface of the filter screen 2 in the first position in a manner such as pressing. For example, in the illustration, the pressing part 3 is arranged on the side of the frame 1, and in the first position, the free end of the cantilever part 32 is stopped 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 installed from the side of the filter screen 2 in a plug-in manner, and the free end of the cantilever part 32 can be stopped on the side edge of the filter screen 2 in the first position.

[0043] The free end of the cantilever part 32 can be swung under the driving of the pressing part 31, that is, the driving of the free end of the cantilever part 32 is achieved by operating the pressing part 31. When the air conditioning device is normally working, the pressing part is not pressed or operated and maintained in the first position, at this time, the free end of the cantilever part 32 can be pressed on the filter screen 2 in a manner substantially parallel to the filter screen 2 to form locking of the filter screen 2, so that the filter screen 2 cannot be dismounted. When the filter screen 2 needs to be dismounted, only the pressing part 31 needs to be pressed to the second position, and in the process of pressing the pressing part 31, the free end of the cantilever part 32 swings from the position substantially parallel to the filter screen 2 to the position inclined to the filter screen 2 under the driving of the pressing part 31, and the inclination of the cantilever part 32 further shortens the length of the projection of the free end of the cantilever part 32 in the direction of the filter screen 2, thereby avoiding the space for dismounting the filter screen 2.

[0044] The filter screen 2 is a component that needs to be frequently cleaned or replaced, and whether it can be conveniently and efficiently dismounted is more intuitive to the use experience. The filter device provided by the present disclosure can achieve locking and unlocking of the filter screen 2 by operating the pressing part 3, which is simple in structure and convenient to operate, and is helpful to improve the competitiveness of the product.

[0045] Considering the reliability of locking the filter screen 2, that is, the filter screen 2 can be reliably accommodated in the accommodation cavity 111 without the user providing external force, in some embodiments, as Figure 7 and Figure 8As shown, the filtering device can further include a first elastic member 4 configured to have an elastic force to maintain the pressing portion 31 at the first position. Specifically, the elastic force provided by the first elastic member 4 causes the pressing portion 31 to be maintained at the first position, and further causes the free end of the cantilever portion 32 to be maintained at the position of the stop filter screen 2. In this way, the filter screen 2 can be reliably accommodated in the accommodation cavity 111 without an external force overcoming the elastic force of the first elastic member 4.

[0046] The present disclosure is not intended to limit the setting position and setting manner of the pressing member 3, and as long as the structure and method of being pressed to lock and unlock the filter screen 2 can be applied in the present disclosure. In some embodiments, referring to Figure 2 、 Figure 7 and Figure 8 , the frame body 1 can further include a box body 13 provided at the side of the frame body 1 for mounting electronic devices such as air quality sensors, and the top cover plate of the box body 13 is provided with a first opening 131 for the pressing portion 31 to extend into, and the side wall of the box body 13 close to the frame body 1 is provided with a second opening 132 for the free end of the cantilever portion 32 to extend into the accommodation cavity 111, wherein the lower opening wall of the second opening 132 is configured as the swing fulcrum of the cantilever portion 32.

[0047] The frame body 1 can be configured in a split structure, specifically, the frame body 1 can include a lower cover body 12 and an upper cover body 11 detachably covered on the top of the lower cover body 12, and the box body 13 is formed at the side of the frame body 1 and can be formed by covering the cover structure of the upper cover body 11 and the supporting plate of the lower cover body 11, which is convenient for mounting and maintaining electronic devices.

[0048] The pressing portion 31 extends from the first opening 131 provided at the top cover plate, and the first opening 131 can be configured as a round hole matched with the shape of the pressing portion 31. The pressing portion 31 is provided at the top cover plate of the box body 13, which is convenient for user operation. The second opening 132 is provided at the side wall close to the frame body 1, which is advantageous for shortening the setting length of the cantilever portion 32 and saving the space occupied in the box body 13.

[0049] In some embodiments, taking the integrated structure of the pressing portion 31 and the cantilever portion 32 as an example, the lower opening wall of the second opening 132 can be directly used as the swing fulcrum, which is simple in structure and convenient to install. In another embodiment, taking the split structure of the pressing portion 31 and the cantilever portion 32 as an example, a fulcrum for the cantilever portion 32 to swing can be separately provided in the box body 13.

[0050] In the embodiment where the pressing portion 31 is arranged on the top cover plate of the box body 13, optionally, in some embodiments, the pressing surface of the pressing portion 31 is configured to be flush with the outer side plate surface of the top cover plate of the box body 13. On the one hand, it can avoid being mistakenly operated, and on the other hand, it is also more beautiful in appearance. Considering the convenience of pressing, the diameter of the pressing portion 31 can range from 9mm to 10mm, that is, the diameter of the pressing portion 31 can be roughly equivalent to the width of a finger.

[0051] Further, as shown in Figure 3 and Figure 4 , the free end of the cantilever portion 32 can be provided with a buckle 321 which extends into the accommodating cavity 111 from the second opening 132. Since in the second position, the free end of the cantilever portion 32 avoids the disassembly space of the filter screen 2 in an inclined manner, in this process, the free end of the cantilever portion 32 has a tendency to slide into the box body 13, therefore, by providing the buckle 321, it can avoid the free end of the cantilever portion 32 from escaping from the second opening 132 in the second position. In addition, in the embodiment where the pressing portion 31 and the cantilever portion 32 are configured as an integral structure, in order to make the free end of the cantilever portion 32 more easily swing, as shown in Figure 4 , a transition connecting portion 322 can also be arranged between the pressing portion 31 and the cantilever portion 32, that is, only the cantilever portion 32 can be deformed to swing, and the transition connecting portion 322 does not deform. It should be noted that, as shown in Figure 8 , in the following description, the length D3 of the cantilever portion 32 only refers to the length excluding the transition connecting portion 322.

[0052] Continuing to refer to Figure 8 , in some embodiments, in the extension direction of the cantilever portion 32, the length D2 of the buckle 321 for stopping the filter screen 2 and the length D3 of the cantilever portion 32 have a ratio ranging from 0.1 to 0.25. The buckle 321 and the cantilever portion 32 in this size ratio range can be used to ensure that the cantilever portion has sufficient elasticity to tilt to avoid the disassembly space of the filter screen 2. For example, in the extension direction of the cantilever portion 32, the length D2 of the buckle 321 for stopping the filter screen 2 can range from 1mm to 2mm, and the length D3 of the cantilever portion 32 can range from 7mm to 9mm. It should be noted that, here, the extension direction of the cantilever portion 32 refers to the direction extending from the fixed end to the free end of the cantilever portion 32 or the opposite direction, that is, Figure 4 and Figure 8 , the left and right directions of the figure.

[0053] In other embodiments, continuing to refer to Figure 8, the distance D4 between the cantilever part 32 and the upper wall of the second opening 132 is greater than or equal to 1.2 times the length D2 of the buckle 321 for stopping the filter screen 2, which makes the cantilever part 32 have enough lifting space, thereby ensuring that the free end of the cantilever part 32 avoids enough space for the filter screen 2 to be disassembled in the second position.

[0054] In the embodiment in which the first elastic member 4 is arranged to maintain the pressing part 31 in the first position. In order to avoid the pressing member 3 from being ejected from the frame 1 under the action of elastic force and inertial force, in some embodiments, as shown in Figure 3 , one end of the pressing part 31 away from the pressing surface is provided with a first limiting part 34, and in the first position, the first limiting part 34 abuts against the inner side plate surface of the top cover plate of the box body 13. It is simultaneously referred to Figure 8 , the radial dimension range of the first limiting part 34 matched with the inner side plate surface of the top cover plate can be 1㎜~1.5㎜, to ensure the reliability of the match.

[0055] Further, as shown in Figure 6 and Figure 10 , the filter device can further include a supporting member 5 fixedly arranged in the interior of the box body 13, and the supporting member 5 is arranged below and spaced apart from the pressing part 31, and the first elastic member 4 is elastically abutted between the supporting member 5 and the pressing part 31. The supporting member 5 is fixedly arranged in the box body 13 and can play the role of mounting and stopping the first elastic member 4. Optionally, the pressing part 31 can be provided with a guide column 33, the first elastic member 4 is a spring and one end of which is sleeved on the guide column 33, and the supporting member 5 is provided with a receiving groove 51 for accommodating the other end of the first elastic member 4, and the receiving groove 51 can be configured as a circular receiving groove matched with the shape of the first elastic member 4, to avoid the first elastic member 4 from being ejected from the receiving groove 51 when the pressing member 3 is pressed.

[0056] The supporting member 5 can be arranged in a suspended manner in the box body 13, and in some embodiments, the supporting member 5 is connected with the inner side plate surface of the top cover plate of the box body 13. Specifically, as shown in Figure 6 and Figure 10 , the inner side plate surface of the top cover plate of the box body 13 is provided with a clamping groove 133, and the supporting member 5 is provided with a second limiting part 52 capable of being matched with the clamping groove 133, for limiting the axial and radial displacement of the supporting member 5. The second limiting part 52 is configured as a buckle and symmetrically arranged on both sides. The supporting member 5 can be made of elastic material, and when installed, the second limiting part 52 can be manually compressed radially inward, and when the second limiting part 52 is aligned with the clamping groove 133, the hand is released, and under the action of elastic force, the second limiting part 52 can be clamped in the clamping groove 133 and will not be ejected without external force. In addition, as shown in Figure 10 , the length D6 of the second limiting part 52 clamped into the clamping groove 133 can be 1㎜~1.5㎜, to ensure the reliability of the clamping.

[0057] As shown previously, in some embodiments, the filter screen 2 is configured to be mounted from the top surface of the frame 1, the pressing member 3 is arranged at the side of the frame 1, and in the first position, the free end of the cantilever portion 32 is stopped at the upper surface of the side edge of the filter screen 2. In order to improve the reliability of the pressing member 3 locking the filter screen 2, as shown in the drawings, the width D1 of the buckle 321 can range from 9mm or more. Figure 5

[0058] The filter screen 2 can be provided with a handle 21 for taking out, which can be a flexible strip, for example, and / or as shown in the drawings, a second elastic member 6 can be arranged between the bottom of the filter screen 2 and the frame 1, which can be a spring, for example, for ejecting the filter screen 2 from the accommodating cavity 111 after the pressing member 3 is unlocked. For example, when the filter screen 2 is locked by the pressing member 3, even if the filter screen 2 is ejected under the action of the second elastic member 6, when the filter screen 2 is unlocked, according to the different positions of the second elastic member 6, for example, the filter screen 2 on the side close to the pressing member 3 can be ejected at least, and then the filter screen 2 is completely taken out by pulling the handle 21.
