Description

Technical Field

[0001] This utility model relates to the field of louvers, specifically a sliding curtain wall ventilation louver device. Background Technology

[0002] In modern architectural design, curtain walls, as an important component of building facades, strive for both aesthetics and functionality. Ventilation louvers, as a common accessory for curtain walls, are used to regulate indoor and outdoor air circulation and lighting.

[0003] Traditional louvers cannot effectively filter dust, impurities, and other pollutants from the air when ventilating, which can easily lead to a decline in indoor air quality. Utility Model Content

[0004] The present invention aims to provide a sliding curtain wall ventilation louver device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A sliding curtain wall ventilation louver device includes a window frame with a ventilation opening. The window frame is rotatably connected to a pivot, which is connected to a flip-up baffle that engages with the ventilation opening. The pivot is connected to a driven gear. The window frame has a sliding groove, and a rack is slidably connected to the side wall of the groove. The driven gear meshes with the rack. A filter frame is detachably connected to the window frame, and a filter screen is connected to the filter frame. The window frame has a placement groove, and the filter frame is slidably connected to the placement groove. The filter frame is connected to a connecting shell, and a rod is slidably connected to the connecting shell. The window frame has an insertion hole, and the rod engages with the insertion hole. The rod is connected to a sliding block, and the connecting shell has a sliding groove. The sliding block is slidably connected to the sliding groove. A spring is sleeved on the rod, and both ends of the spring are connected to the sliding block and the side wall of the sliding groove, respectively.

[0007] Preferably, the window frame is rotatably connected to a drive gear, the drive gear meshes with a rack, the window frame is connected to a stepper motor, the output end of the stepper motor is connected to a connecting rod, the connecting rod is rotatably connected to the window frame, and the connecting rod is connected to the drive gear.

[0008] Preferably, the flip-up baffle is connected to a sealing strip, and the sealing strip is made of elastic silicone material.

[0009] Preferably, the rack is connected to a T-shaped bar, and the sidewall of the slide groove is provided with a T-shaped groove, wherein the T-shaped bar and the T-shaped groove are slidably connected.

[0010] Preferably, a fixing block is connected to the side wall of the ventilation opening, and the flip-up baffle cooperates with the fixing block.

[0011] The beneficial effects of this technical solution compared to existing technologies are as follows:

[0012] (1) This solution, by setting up a filter frame and filter screen, can intercept dust and debris in the air, preventing them from entering the room with the airflow, significantly reducing the rate of dust accumulation and the workload of daily cleaning. It achieves air purification while keeping the vents open, realizing "continuous ventilation without dust entry," avoiding sacrificing indoor air quality due to concerns about pollution. Through the setting of a structure including a rod, socket, sliding block, sliding groove, and spring, the filter frame is fixed in the placement groove of the window frame by the cooperation of the rod and socket. The spring pushes the rod to automatically lock it. Disassembly only requires pulling the rod to compress the spring, allowing the filter frame to be removed, facilitating regular cleaning or filter replacement, and making maintenance convenient. Installation and disassembly can be completed without tools, reducing maintenance difficulty. Users can clean the filter screen regularly according to the frequency of use to maintain ventilation efficiency and avoid affecting ventilation effect due to filter clogging.

[0013] (2) By setting up a structure including a rotating shaft, a flipping baffle, a driven gear, a slide groove, a rack, a driving gear, a stepper motor, and a connecting rod, the motor drives the driving gear to rotate, causing the rack to slide. The meshing of the driven gear and the rack converts the linear sliding of the rack into the rotational motion of the rotating shaft, which in turn drives the flipping baffle to flip, thus opening or closing the ventilation opening. This mechanical transmission structure is simple and reliable, with high transmission efficiency, and can precisely control the flipping angle of the baffle to adjust the ventilation volume. It allows for adjustment of the opening angle according to actual needs, balancing ventilation effect with indoor temperature and noise control requirements. In windy weather, the opening angle can be reduced to prevent strong winds from entering; when rapid indoor ventilation is required, the baffle can be fully opened.

[0014] (3) By setting up an elastic silicone sealing strip, when the baffle is closed, the sealing strip fits tightly against the edge of the ventilation opening, effectively blocking external wind, rain, dust and noise, and improving the sealing and thermal insulation of the curtain wall. The elastic properties of silicone material can also compensate for installation errors or structural deformation during long-term use, ensuring a long-lasting and reliable sealing effect.

[0015] (4) By setting T-slots and T-grooves, the rack is provided with lateral restraint to prevent it from shifting or falling off during sliding, thereby enhancing the stability of the transmission structure. At the same time, the T-shaped structure can disperse the lateral force on the rack, reduce wear, and extend the service life of the device.

[0016] (5) By setting a fixed block, a support point is provided when the baffle is closed, which prevents the baffle from shaking due to external force, further improving the stability of the closed state, while reducing the stress deformation of the sealing strip and extending the service life of the seal.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0023] like Figure 1-4 The sliding curtain wall ventilation louver device shown includes a window frame 2 with ventilation openings 4. The window frame 2 is rotatably connected to several rotating shafts 6, and each rotating shaft 6 is connected to a flip baffle 3. The flip baffles 3 are arranged horizontally to cover the ventilation openings 4. All the flip baffles 3 cooperate with the ventilation openings 4. One end of each rotating shaft 6 is connected to a driven gear 11. The window frame 2 has a sliding groove 13, and a rack 12 is slidably connected to the side wall of the sliding groove 13. Each driven gear 11 meshes with the rack 12. When the rack 12 slides horizontally along the sliding groove 13, the meshing driven gears 11 drive all the rotating shafts 6 to rotate synchronously, causing the flip baffles 3 to flip synchronously, thereby achieving uniform adjustment of the opening angle of the ventilation openings 4. A filter frame 8 is detachably connected to the other end of the window frame 2. A filter screen 9 is connected to the inner wall of the filter frame 8. The window frame 2 has a placement groove 7. The filter frame 8 is slidably connected to the placement groove 7. Connecting shells 21 are connected to both ends of the filter frame 8. Insert rods 17 are slidably connected to the two connecting shells 21. Insert holes 18 are opened in the window frame 2 corresponding to the insert rods 17. The two insert rods 17 cooperate with the corresponding insertion holes 18. Sliding blocks 19 are connected to the two insert rods 17. Sliding grooves 20 are opened in the two connecting shells 21. The two sliding blocks 19 are slidably connected to the corresponding sliding grooves 20. Springs 22 are sleeved on the outer walls of the two insert rods 17. The two ends of the two springs 22 are connected to the side walls of the corresponding sliding blocks 19 and sliding grooves 20, respectively. When installing the filter frame 8, the insertion rod 17 automatically inserts into the socket 18 under the pushing force of the spring 22, thus locking it in place. To remove it, pull the insertion rod 17 to compress the spring 22 using the sliding block 19, causing the insertion rod 17 to exit the socket 18, allowing the filter frame 8 to be removed. The preload of the spring 22 ensures the filter frame 8 is securely fixed, preventing it from falling off due to vibration.

[0024] like Figure 1 , 3 As shown, a drive gear 16 is rotatably connected to the inner wall of the window frame 2. The drive gear 16 meshes with the rack 12. A stepper motor 1 is connected to the outer wall of the window frame 2. A connecting rod 10 is connected to the output end of the stepper motor 1. The connecting rod 10 is rotatably connected to the window frame 2. The end of the connecting rod 10 away from the stepper motor 1 is connected to the drive gear 16. When the stepper motor 1 is started, the output end of the stepper motor 1 drives the connecting rod 10 to rotate, and the drive gear 16 rotates accordingly. Through the meshing of the drive gear 16 and the rack 12, the rack 12 slides along the slide groove 13.

[0025] like Figure 2 As shown, each flip-up baffle 3 has a sealing strip connected to its upper and lower edges, and the sealing strip is made of elastic silicone. When the flip-up baffle 3 is closed, the sealing strips of adjacent baffles are pressed together and adhered to each other. At the same time, the sealing strips at the edges of the baffles are in close contact with the side walls of the vents 4, forming a sealed barrier that effectively blocks rainwater and noise. The elastic silicone has high flexibility and weather resistance, and is not prone to hardening or cracking after long-term use.

[0026] like Figure 3 As shown, a T-shaped bar 15 is connected to one side of the rack 12, and a T-shaped groove 14 is formed on the side wall of the slide groove 13. The T-shaped bar 15 and the T-shaped groove 14 are slidably connected. The T-shaped structure restricts the displacement of the rack 12 in the direction perpendicular to the slide groove 13, preventing it from coming out, and at the same time provides a guiding function to ensure that the rack 12 moves smoothly in a straight line.

[0027] like Figure 2 As shown, the upper and lower side walls of the vent 4 are respectively connected to fixing blocks 5, and the top and bottom flip baffles 3 cooperate with the corresponding fixing blocks 5. When the baffles are flipped to the closed state, the top and bottom baffles abut against the corresponding fixing blocks 5. The fixing blocks 5 provide mechanical support, limit the excessive flipping of the baffles, and enhance the sealing effect by squeezing the sealing strip.

[0028] The specific implementation process is as follows:

[0029] In use, stepper motor 1 is started. Upon receiving an electrical signal, stepper motor 1 begins to rotate. Its output terminal drives the drive gear 16 to rotate via connecting rod 10. The drive gear 16 meshes with rack 12, converting the rotational motion into the horizontal linear motion of rack 12. When rack 12 slides, it drives each rotating shaft 6 to rotate synchronously through the meshing driven gear 11. The rotation of the rotating shaft 6 causes the flip baffle 3 to flip, and the opening angle is precisely controlled by the number of rotation steps of stepper motor 1. At this time, outdoor air enters through vent 4, first passing through the filter screen 9 in filter frame 8 to intercept dust and debris, and then clean air flows into the room, achieving simultaneous "ventilation + purification".

[0030] When closed, stepper motor 1 rotates in reverse, driving gear 16 to rotate in reverse, which in turn drives rack 12 to slide in reverse. Rack 12 causes driven gear 11 to rotate shaft 6, causing flip baffle 3 to flip to the 0° closed state. The elastic silicone sealing strips on the upper and lower edges of each baffle are tightly pressed against adjacent baffles and the sidewalls of vent 4, forming a multi-layer sealing interface to block airflow leakage. The top and bottom baffles abut against the fixing blocks 5 on the upper and lower sidewalls of vent 4, respectively, ensuring the baffle position is fixed, while further compressing the sealing strips to improve sealing performance.

[0031] After a period of use, the filter screen 9 will accumulate dust and need to be cleaned or replaced. Hold the insertion rod 17 with both hands and pull it outwards to compress the spring 22. After the insertion rod 17 is completely removed from the insertion hole 18 of the window frame 2, pull the filter frame 8 outwards horizontally along the placement groove 7 to remove the filter screen for cleaning. Insert the cleaned or replaced filter screen into the filter frame 8, align it with the placement groove 7 of the window frame 2, and slowly push it in along the placement groove 7. When the insertion rod 17 is aligned with the insertion hole 18, the elastic force of the spring 22 will cause the insertion rod 17 to automatically insert into the insertion hole 18, thus completing the installation.
