Detailed Description of the Invention

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0026] Embodiment 1: Please refer to Figures 1 - 5 As shown, the present utility model provides a technical solution: A foldable activated carbon net filter, including an outer frame 1, and an activated carbon net installation groove 101 for installing a carbon net is opened on the outer frame 1.

[0027] With the setting of the activated carbon net installation groove 101 in this technical solution, when in use, first prepare a filter carbon net with the same size as the activated carbon net installation groove 101, and fixedly install the filter carbon net in the activated carbon net installation groove 101. That's it.

[0028] Example 2: The technical content disclosed in this example is an improvement based on the above Example 1. The existing final volume is still relatively large. In situations where space saving or high portability requirements are needed, such a filter may not be portable enough and occupies more storage or carrying space. The technical solution is as follows Figure 1 and Figure 2 As shown, the folding assembly of the filter is disclosed. A connecting member 2 is fixedly connected to the upper end of the outer frame 1 provided. A collar 3 is sleeved outside the connecting member 2. And a first connecting frame 4 is fixedly connected to the bottom end of the collar 3. A hinge 5 is fixedly connected to the first connecting frame 4. And a second connecting frame 6 is fixedly connected to the end of the hinge 5 away from the first connecting frame 4. Slots 7 are formed on both the first connecting frame 4 and the second connecting frame 6. There are four outer frames 1, and the four outer frames 1 are symmetrically arranged in pairs. And the four outer frames 1 are rotationally connected through the hinge 5. The connecting member 2 is arranged in an arc structure and is rotationally connected to the collar 3. There are four groups of both the connecting member 2 and the collar 3. And the four connecting members 2 correspond to the four outer frames 1 one by one. The collars 3 are symmetrically arranged in pairs with respect to the first connecting frame 4. And one group of the collars 3 is fixedly connected to the second connecting frame 6.

[0029] In this technical solution, as shown in Figure 1 With the setting of the hinge 5, the four outer frames 1 are driven by a set of hinges 5 to fit together with each other. At the same time, the first connecting frame 4 and the second connecting frame 6 will rotate around the other set of hinges 5 at their bottom ends, so as to fold the three-dimensional filter into a planar type. The operation is simple, reducing the space occupied by the filter during storage and transportation.

[0030] It adopts the technical solution as shown in Figure 2 First, take out a set of filter carbon nets of the same size as the slots 7 and fixedly install the filter carbon nets in the slots 7. When it is necessary to transport the outer frame 1, push the four outer frames 1, so that the four outer frames 1 rotate driven by the hinge 5, so that the originally three-dimensional outer frames 1 approach each other in pairs to form a rectangle. Immediately afterwards, the outer frame 1 will drive the connecting member 2 to rotate, so that the connecting member 2 rotates in the collar 3. Since the four collars 3 are separately connected to the first connecting frame 4 and the second connecting frame 6, the collar 3 drives the first connecting frame 4 and the second connecting frame 6 to rotate around the hinge 5 at their bottom ends as the axis. At this time, the first connecting frame 4 and the second connecting frame 6 rotate and fit together, and the storage can be completed.

[0031] Example 3: The technical content disclosed in this example is a further improvement based on the above Example 1 and Example 2. The existing filter has a poor fixing effect. To further solve this technical problem, the technical solution is as follows Figures 3 - 5As shown, a clamping component of a filter is disclosed. The first connecting frame 4 and the second connecting frame 6 are clamped and connected through a connecting mechanism 8, and a pull rod 10 is fixedly connected to the connecting mechanism 8. The connecting mechanism 8 includes a first clamping block 801, a second clamping block 802 and a limiting groove 803. The first clamping block 801 is fixedly arranged on the side of the first connecting frame 4, and two groups of the first clamping blocks 801 are symmetrically arranged with respect to the first connecting frame 4. The bottom ends of the two first clamping blocks 801 are fixedly connected to the second clamping block 802, and limiting grooves 803 are opened on both the second clamping block 802 and the first clamping block 801. The second clamping block 802 is perpendicular to the first clamping block 801, and inclined surfaces are opened on both the second clamping block 802 and the first clamping block 801. The connecting mechanism 8 further includes a fixing block 804, a sliding groove 805 and a limiting block 806. The fixing block 804 is fixedly arranged on the side of the second connecting frame 6, and two groups of the fixing blocks 804 are symmetrically arranged with respect to the second connecting frame 6. Sliding grooves 805 are opened in both the two fixing blocks 804, and a limiting block 806 is slidably connected in the sliding groove 805, and the limiting block 806 is fixedly connected to the pull rod 10. A compression spring 9 is fixedly arranged in the sliding groove 805, and one end of the compression spring 9 is fixedly connected to the inner wall of the sliding groove 805, and the end of the compression spring 9 away from the inner wall of the sliding groove 805 is fixedly connected to the limiting block 806. The limiting block 806 corresponds to the limiting groove 803, and inclined surfaces are opened at both the upper and lower ends of the limiting block 806.

[0032] In the present technical solution, as Figure 3 shown, by means of the arrangement of the first clamping block 801 and the second clamping block 802, when the filter is folded and stored or opened, both the first clamping block 801 and the second clamping block 802 can be connected to the limiting block 806 in the fixing block 804, achieving rapid positioning and ensuring the stable structure of the filter after folding or opening.

[0033] It adopts the technical solution as Figure 4 and Figure 5 shown. In the folded state, the first connecting frame 4 will drive the first clamping block 801 and the second clamping block 802 to rotate downward simultaneously, and the second connecting frame 6 will drive the fixing block 804 to rotate downward. At this time, the first clamping block 801 and the fixing block 804 approach each other, so that the first clamping block 801 squeezes the limiting block 806 in the fixing block 804. After being squeezed, the limiting block 806 will slide backward along the inner wall of the sliding groove 805 and squeeze the compression spring 9 to contract during the sliding process. When the first connecting frame 4 and the second connecting frame 6 are in contact, at this time, the first clamping block 801 stops rotating, and the limiting block 806 will be aligned with the limiting groove 803. Thus, under the elastic force of the compression spring 9, the limiting block 806 is pushed into the limiting groove 803 for limiting to prevent the first connecting frame 4 and the second connecting frame 6 from separating;

[0034] When expansion is required, pull the pull rod 10. The pull rod 10 will drive the limit block 806 to slide along the inner wall of the sliding groove 805 and squeeze the compression spring 9 to contract, so as to separate the limit block 806 from the limit groove 803. At this time, rotate the first connecting frame 4 and the second connecting frame 6, so that the first latch 801 and the fixed block 804 move away from each other. At this time, the second latch 802 will approach the fixed block 804 and squeeze the limit block 806 to contract. When the first connecting frame 4 and the second connecting frame 6 are fully expanded, the second latch 802 stops moving, and the limit block 806 will align with the limit groove 803 on the second latch 802. Thus, under the drive of the compression spring 9, it is limited to prevent loosening and improve the stability of the connection.
