[0055] The cover assembly 110 has a ventilation area 111 for air flow.

[0056] The filter 120 is adjustable in position to block or avoid the ventilation area 111. When air flows into the ventilation area 111, the filter 120 blocks the ventilation area 111 to filter the incoming air flow and ensure the cleanliness of the air flow.

[0057] The filter structure has a disassembly opening 140 for disassembling and assembling the filter 120, and the cover plate 130 is adjustably arranged at the disassembly opening 140, so that the filter 120 is positioned inside the cover assembly 110 by closing the disassembly opening 140, or the filter 120 is removed from the disassembly opening 140 by opening the disassembly opening 140. That is, when the cover plate 130 closes the disassembly opening 140, the filter 120 is positioned inside the cover assembly 110, and the filter 120 is at a working position for filtering the incoming air flow; when the cover plate 130 opens the disassembly opening 140, the filter 120 can be removed from the disassembly opening 140. The user can completely take out the filter 120 for cleaning by himself. Compared with the general setting of cleaning inside the indoor unit of the air conditioner 30, the filter 120 can be fully cleaned in this embodiment to prevent problems such as incomplete cleaning of the filter 120 affecting the incoming air volume.

[0058] Figure 4 An exploded view of a ventilation device according to the present invention is shown. Figure 4 The filtering structure also includes a driving component 150 .

[0059] The driving assembly 150 is drivingly connected to the filter screen 120 to drive the filter screen 120 to move.

[0060] Figure 3FIG. 2 is a schematic structural diagram of another embodiment of a ventilation device according to the present invention. Figure 3 When the cover plate 130 is in a closed position for covering the disassembly opening 140 , the cover plate 130 is located on the outside of the filter 120 , so that the filter 120 can be movably positioned on the inside of the cover assembly 110 along a predetermined trajectory under the driving action of the driving assembly 150 by covering the filter 120 .

[0061] When the cover plate 130 is in the open position to avoid the disassembly opening 140 , the cover plate 130 avoids the disassembly opening 140 , so that the filter screen 120 is moved out of the disassembly opening 140 under the driving action of the driving assembly 150 .

[0062] See also Figure 4 The driving assembly 150 includes a roller assembly 151. The roller assembly 151 includes a gear portion 1511. The filter screen 120 is provided with a rack portion 121 meshed with the gear portion 1511. The roller assembly 151 is rotatably arranged to drive the filter screen 120 to move. Through the coordinated movement of the gear portion 1511 and the rack portion 121, the filter screen 120 is movably arranged along a predetermined track.

[0063] The drum assembly 151 further includes a drum 1512. The drum 1512 includes a first rotating shaft and a plurality of gears disposed on the first rotating shaft, wherein the axes of the plurality of gears are coaxially disposed with the axis of the first rotating shaft, and the number of the plurality of gears depends on the length of the first rotating shaft.

[0064] See also Figure 4 The driving assembly 150 further includes a driving motor 152. The driving motor 152 is drivingly connected to the roller assembly 151 to drive the roller assembly 151 to rotate.

[0065] In some embodiments, the drum assembly 151 includes a drum 1512 and a gear part 1511. The gear part 1511 includes two gears, and the two gears are respectively engaged with the two rack parts 121 on the filter screen 120 to drive the filter screen 120 to move. At this time, the drum 1512 is located in the middle of the gears of the gear part 1511, and the first rotating shaft is located in the shaft holes of the two gears, so that the drum 1512 is used to improve the movement stability of the gear part 1511 and prevent the gear part 1511 from being separated from the rack part 121 due to external factors. In addition, the output shaft of the driving motor 152 also extends into the shaft hole of the gear in the gear part 1511 to drive the gear part 1511 to rotate.

[0066] See also Figure 3 The inner wall surface of the cover plate 130 includes an arc surface. When the cover plate 130 blocks the disassembly opening 140, a movement gap is formed between the arc surface and the drum assembly 151 for the filter screen 120 to pass through.

[0067] In some embodiments, the center line of the arc surface coincides with the axis of the gear portion 1511 to prevent the filter 120 from moving.

[0068] Figure 5 FIG. 1 shows a schematic structural diagram of the cover plate 130 in the filter structure according to the present invention. Figure 5 The cover plate 130 includes two end plates 132 and a shielding plate 133 .

[0069] The two end plates 132 are disposed opposite to each other along the width direction of the filter screen 120. Both ends of the shielding plate 133 are respectively connected to the two end plates 132, and the shielding plate 133 is used to shield the disassembly opening 140.

[0070] In some embodiments, the shielding plate 133 is a curved plate to prevent the filter 120 from moving.

[0071] Figure 2 Shows Figure 1 A magnified view of the ventilation device in FIG. Figure 2 The filtering structure also includes a locking cover 160 .

[0072] The locking cover 160 is disposed at one side of the disassembly opening 140 . The locking cover 160 is provided with a first locking portion 161 . The cover plate 130 is provided with a second locking portion 134 for cooperating with the first locking portion 161 .

[0073] When the cover plate 130 is in a closed position to cover the assembly and disassembly opening 140 , the first locking portion 161 and the second locking portion 134 cooperate with each other to lock the position of the cover plate 130 .

[0074] In some embodiments, one of the first locking portion 161 and the second locking portion 134 is a buckle portion, and the other of the first locking portion 161 and the second locking portion 134 is a bayonet portion for buckling with the buckle portion.

[0075] See also Figure 5 The filtering structure also includes a first elastic member 170 .

[0076] The first elastic member 170 is connected to the cover plate 130 , so that when the first locking portion 161 and the second locking portion 134 are disengaged, the cover plate 130 is moved to a position where the disassembly opening 140 is opened under the action of the first elastic member 170 .

[0077] See also Figure 5 A limiting column 135 and a stop block 136 are provided on the cover plate 130. The first elastic member 170 is a torsion spring, which is sleeved on the limiting column 135. One torsion arm of the torsion spring abuts against the stop block 136, and the other torsion arm of the torsion spring is used to abut against the first limiting rib 212 on the support frame 190, so as to utilize the elastic force of the torsion spring itself to rotate and open the cover plate 130, saving time and effort.

[0078] The filtering structure further includes a second elastic member 180 .

[0079] The second elastic member 180 is connected to the locking cover 160 , so that the locking cover 160 is in a position locked with the cover plate 130 under the action of the second elastic member 180 .

[0080] The second elastic member 180 is a spring, one end of which is used to abut against the support frame 190, and the other end of the spring abuts against the locking cover 160, so that when the locking cover 160 is pressed, the locking cover 160 compresses the spring and moves downward, so that the first locking portion 161 and the second locking portion 134 are disengaged.

[0081] See also Figure 2 The spring is sleeved on the protruding column on the support frame 190, and the end is fixed to the support frame 190 by adhesive such as glue. The other end of the spring is sleeved on the protruding column on the locking member, so that the position of the locking member can be changed by the spring. Figure 1 Since the support frame 190 is provided with a third limiting rib 211, the third limiting rib 211 and the support frame 190 itself form a slot for limiting the displacement of the locking member, so as to ensure that the displacement of the locking member is up and down without swinging.

[0082] See also Figure 4 The filtering structure also includes a detection component 200.

[0083] The detection component 200 is disposed at the end of the predetermined track, so that when the filter 120 moves to the predetermined position, the detection component 200 sends a removal signal for removing the filter 120. Specifically, the detection component is a micro switch.

[0084] In some embodiments, the support frame 190 is provided with a predetermined track 191 for accommodating the movement of the filter 120, and a detection component 200 is provided at the end of the predetermined track 191. When one end of the filter 120 moves to the end of the predetermined track 191, the filter 120 is provided with the detection component 200, and when the detection component 200 transmits a signal to the display screen of the air conditioner 30, the display screen can prompt the user to perform an operation.
