Technical Field

[0001] The utility model provides an indoor air outlet structure, which relates to the technical field of indoor exhaust. Background Art

[0002] The layout principle of indoor air supply and exhaust vents is very important, which directly affects the circulation and comfort of indoor air. The layout principle is to ensure the uniformity and comfort of air circulation, reasonably arrange the position and quantity, and avoid unnecessary impact on the human body and the interior.

[0003] The existing indoor exhaust port is generally connected to the exhaust fan, and the exhaust port can be controlled to open and close to control the in and out flow of air. However, after the exhaust port is controlled to be opened, dust and foreign matter will inevitably enter the room through the exhaust port. The existing blocking method is generally to use a filter. However, if the pore size of the filter used is large, it cannot achieve a good filtering effect. If the pore size of the filter used is small, more dust will be adsorbed on the surface of the filter, affecting the exhaust effect. The filter needs to be cleaned frequently, which is more troublesome.

[0004] Therefore, it is necessary to have an indoor exhaust vent structure with both filtering and effective exhaust performance. Summary of the invention

[0005] In order to overcome the problem that dust and foreign matter can enter the room after the existing exhaust vent is opened, and when using filters with different apertures, there will be the disadvantages of being unable to filter dust or excessively absorbing dust and affecting the exhaust effect, the utility model provides an indoor exhaust vent structure with both filtering and effective exhaust performance.

[0007] Furthermore, the two baffles are L-shaped and centrosymmetrical.

[0008] Furthermore, the power assembly includes a first electric slide rail installed on the mounting frame, a rack is slidably arranged on the first electric slide rail, the rotating shaft of the lily leaf penetrates the mounting frame, and a missing gear is fixedly connected to the rotating shaft of each lily leaf, and each missing gear is meshed with the rack.

[0009] Furthermore, it also includes a mounting block installed on the inner walls on both sides of the exhaust duct, two guide rods are fixedly connected to the mounting block, and clamping blocks are rotatably provided on the two guide rods. Two elastic parts are wound around the guide rods, and the upper and lower ends of the elastic parts are respectively fixedly connected to the clamping blocks and the mounting blocks, and the activated carbon net is clamped between the clamping blocks.

[0010] Furthermore, it also includes two second electric slide rails installed on the exhaust duct, and the two second electric slide rails are slidably provided with a connecting block, and a brush is installed on the connecting block.

[0011] Furthermore, a collecting frame is clamped on the exhaust duct, and the collecting frame is located directly below the connecting block and the brush.

[0012] Furthermore, a sealing strip is installed on the inner wall of the installation frame.

DETAILED DESCRIPTION

[0023] The utility model is described in detail below in conjunction with the accompanying drawings.

[0024] Embodiment 1: An indoor air outlet structure, see Figure 1-Figure 3 As shown, it includes an exhaust duct 1, a mounting frame 2, lily blades 3 and a power component. The exhaust duct 1 is installed with a mounting frame 2 on one side near the air outlet by bolt connection. The mounting frame 2 is rotatably provided with a plurality of lily blades 3 for controlling air circulation. The mounting frame 2 is provided with a power component for driving the lily blades 3 to rotate, and also includes a motor 4, a baffle 5, a pulley group 6 and a protective shell 601. The exhaust duct 1 is rotatably provided with two upper and lower baffles 5. The two baffles 5 are L-shaped with a central symmetry so that the two baffles 5 can be combined to form a central symmetry. A vortex airflow space is formed between the two baffles 5 to prevent outside air from bringing dust into the room, while the indoor air can be discharged to the outside. The rotating shafts of the two baffles 5 penetrate to the outside of the exhaust duct 1, and a pulley group 6 is commonly arranged on the rotating shafts of the two baffles 5. A motor 4 is installed on the outer wall of the exhaust duct 1 near the pulley group 6 by bolt connection. The output shaft of the motor 4 is fixedly connected to the rotating shaft of a baffle 5 by a coupling. A protective shell 601 is installed on the outer wall of the exhaust duct 1 by bolt connection, and the motor 4 and the pulley group 6 are located in the protective shell 601.

[0025] See also Figure 3 As shown, the power assembly includes a first electric slide rail 7 installed on the top of the mounting frame 2 by means of bolt connection, a rack 8 is horizontally slidably arranged on the first electric slide rail 7, the rotating shaft of the lily blade 3 penetrates the mounting frame 2, and a missing gear 9 is fixedly connected to the rotating shaft of each lily blade 3 by means of a key connection, and each missing gear 9 is engaged with the rack 8.

[0026] When exhaust is needed, the rack 8 is driven to slide in translation by starting the first electric slide rail 7, so that the rack 8 drives the missing gear 9 to rotate, and the missing gear 9 drives the lily blade 3 to rotate on the mounting frame 2, so that the exhaust port is connected with the outside world; when dust and foreign matter need to be prevented from entering the room, a baffle 5 is driven to rotate by starting the motor 4, and a baffle 5 is driven to rotate synchronously through the transmission of the pulley group 6, and the two baffles 5 are erected. When exhausting air from the room to the outside, the indoor wind direction is blocked by the upper baffle 5 and then flows downward, The air in the exhaust duct 1 is ventilated outward through the gap between the two baffles 5. If the outside wind blows dust into the exhaust duct 1, the two staggered baffles 5 will block the dust together. The straight wind will be blocked by the baffles 5 and most of the power will be removed, and it will be unable to climb up and cross the baffles 5. At this time, the dust falls and cannot enter the room. If smoother ventilation is required, the two baffles 5 can be rotated to the side away from each other through the cooperation of the motor 4 and the pulley group 6, so that the gap between the two baffles 5 can be expanded, and the ventilation effect of the exhaust duct 1 will be better.

[0027] Example 2: Based on Example 1, refer to Figure 4 and Figure 5 As shown, it also includes a mounting block 11 installed on the inner walls of both sides of the exhaust duct 1 by bolt connection, and two guide rods 12 are fixedly connected to the mounting block 11 by welding. The two guide rods 12 are rotatably provided with a clamping block 13, and two upper and lower elastic members 14 are wound around the guide rods 12. The upper and lower ends of the elastic member 14 are fixedly connected to the clamping block 13 and the mounting block 11 by welding, and the activated carbon net 10 for filtering impurities and absorbing harmful gases is clamped between the clamping blocks 13.

[0028] When air circulates in the exhaust duct 1, the activated carbon net 10 can absorb harmful substances in the air exhausted from indoor to outdoor, and perform green discharge. At the same time, the activated carbon net 10 can absorb impurities and harmful substances in the air entering from outdoor to avoid causing damage to indoor users. If the activated carbon net 10 needs to be replaced, the clamp block 13 is rotated along the guide rod 12. At this time, the elastic member 14 is twisted and deformed by force, so that the clamp block 13 loosens the activated carbon net 10, and then the activated carbon net 10 can be taken out for replacement. After the replacement is completed, the clamp block 13 is loosened. At this time, the elastic member 14 drives the clamp block 13 to rotate and reset, so that the clamp block 13 clamps the activated carbon net 10 and fixes it in the exhaust duct 1.

[0029] See also Figure 6 As shown, it also includes two second electric slide rails 15 installed on the exhaust duct 1 near the installation frame 2 by bolt connection, and a connecting block 16 is provided on the two second electric slide rails 15 for sliding up and down together, and a brush 17 for cleaning the lily leaves 3 is installed on the connecting block 16 by bolt connection.

[0030] When the lily blade 3 is used for a long time, a large amount of dust will be adhered to it. At this time, the two second electric slide rails 15 are started to drive the connecting block 16 to slide up and down, so that the connecting block 16 drives the brush 17 to clean the dust on the lily blade 3.

[0031] See also Figure 6 As shown, a collecting frame 18 for collecting dust is clamped on the exhaust duct 1, and the collecting frame 18 is located directly below the connecting block 16 and the brush 17; a sealing strip 19 is installed on the inner wall of the installation frame 2 by bonding.

[0032] The collecting frame 18 can collect dust and impurities swept off the lily blades 3. The collected dust can be cleaned by pulling the collecting frame 18 away from the exhaust duct 1. When the lily blades 3 are rotated and closed, the sealing strip 19 can enhance the tightness between the mounting frame 2 and the lily blades 3 to prevent outdoor air from entering the room.
