Description

Technical Field

[0001] This utility model relates to the field of air outlet structure technology, and in particular to a central air conditioning air outlet structure. Background Technology

[0002] Central air conditioning vents are the terminal components in a central air conditioning system that connect the ductwork to the indoor space. They are also the "exit" for airflow into the room. Their core function is to deliver the cooled (or heated) air processed by the air conditioning unit to the room in a uniform and directional manner. At the same time, as a "connection hub" between the room and the ductwork, they undertake functions such as airflow guidance, dust interception, and aesthetic decoration. They are key components that affect the indoor air supply effect, comfort, and air quality.

[0003] A central air conditioning outlet structure, disclosed in Chinese Patent No. CN221780906U, includes a grille. A connecting frame is fixedly installed on the four sides of the grille, and a sliding cleaning structure is fixedly installed on the inner surface of the connecting frame. This central air conditioning outlet structure allows for quick assembly and disassembly of the grille via connecting rods and rotating buckles, facilitating the cleaning of accumulated dirt. The layered, overlapping connection structure reduces the use of screws, simplifying the structure and making installation easier. The sliding cleaning structure allows for regular cleaning of dust on the grille and under the air vent. A rotating rod can be used to rotate a soft brush to sweep away dust, and the rotating rod can also be slid up and down to clean the grille using a lever.

[0004] When an air conditioner is left unused during seasonal changes, the air vents and ducts are directly connected, allowing external dust to enter the ducts and accumulate on core components such as the impeller and evaporator. Although some products are designed with removable dust covers, they need to be installed manually, which most users tend to forget. Furthermore, gaps are easily left after installation due to poor fit, resulting in limited dust protection. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a central air conditioning vent structure that solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a central air conditioning vent structure, including a strip-shaped vent frame, with a guide grille fixedly connected to the inner end of the strip-shaped vent frame, and side auxiliary seats symmetrically fixedly connected to the left and right ends of the strip-shaped vent frame. A hollow side frame is detachably connected to the upper end of the side auxiliary seats, and an internal vertical plate is fixedly connected to the inner sidewall of the two hollow side frames at their respective ends. A primary corrugated dustproof plate and a secondary corrugated dustproof plate are fixedly connected to the two internal vertical plates at their respective ends. Metal clips are fixedly connected to the ends of the primary and secondary corrugated dustproof plates at their respective ends away from the internal vertical plates. A convenient gripping groove is provided at the ends of the two metal clips at their respective ends. A protruding vertical plate is fixedly connected to the ends of the two hollow side frames at their respective ends. The two protruding vertical plates are staggered vertically. Two left-right corresponding guide horizontal ropes are fixedly connected between the two internal vertical plates, and the two guide horizontal ropes pass through the left and right sides of the primary corrugated dustproof plate.

[0007] As a further technical solution of this utility model, the corresponding metal rods on the left and right are magnetically connected to the protruding upright plate, and the secondary corrugated dustproof plate and the primary corrugated dustproof plate are arranged alternately in the upper and lower positions.

[0008] As a further technical solution of this utility model, the lower end of the hollow side frame is fixedly connected to a removable connecting plate layer, and the left and right ends of the removable connecting plate layer are symmetrically provided with side inner grooves.

[0009] As a further technical solution of this utility model, the upper left and right sides of the detachable connecting plate layer are symmetrically provided with connecting grooves, and the inner groove and the connecting groove on the same side are interconnected.

[0010] As a further technical solution of this utility model, a protruding follower plate is slidably connected to the inner end of the side groove, and a vertical hand grip plate extending to the outside of the connecting groove is fixedly connected to the upper end of the protruding follower plate.

[0011] As a further technical solution of this utility model, a pressure spring is fixedly connected to one end of the two vertical hand grips that are far apart from each other, and the pressure spring is connected to the inner side wall of the connecting groove.

[0012] As a further technical solution of this utility model, the left and right inner walls of the side auxiliary seat are symmetrically provided with slots, and the two slots and the corresponding protruding follower plates are connected to each other.

[0013] This utility model provides a central air conditioning vent structure, which has the following advantages compared with the prior art: This design presents a central air conditioning vent structure. The solution utilizes a double-layered dustproof structure consisting of a primary corrugated dustproof plate and a secondary corrugated dustproof plate. When the air conditioner is not in use for an extended period, the primary corrugated dustproof plate completely covers the inner side of the airflow guide grille, forming a sealed barrier that prevents external dust from entering the vent through the air duct. This prevents dust accumulation in the airflow guide grille and air duct after prolonged disuse. When the entire strip-shaped vent frame needs to be disassembled for deep cleaning or maintenance, the secondary corrugated dustproof plate is pulled outwards using the easy-grip groove. This forms a supporting layer with the primary corrugated dustproof plate, intercepting dust adhering to its surface and preventing it from falling directly into the room during disassembly. Before cleaning, the easy-to-disassemble connecting plate layers allow for quick installation and removal. No tools are required, and the entire operation can be completed without specialized equipment. This ensures efficient airflow during long-term use while completely solving the problems of dust accumulation during shutdown and secondary pollution during disassembly. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4This utility model provides a central air conditioning vent structure technical solution: including a strip-shaped vent outer frame 1, a guide grille 2 fixedly connected to the inner end of the strip-shaped vent outer frame 1, side auxiliary seats 3 symmetrically fixedly connected to the left and right ends of the strip-shaped vent outer frame 1, a hollow side frame 4 detachably connected to the upper end of the side auxiliary seat 3, an inner vertical plate 5 fixedly connected to the inner side wall of the two hollow side frames 4 at their respective ends, a primary corrugated dustproof plate 6 and a secondary corrugated dustproof plate 11 fixedly connected to the two inner vertical plates 5 at their respective ends, a metal clamping rod 7 fixedly connected to the end of the primary corrugated dustproof plate 6 and the secondary corrugated dustproof plate 11 away from the inner vertical plate 5, a convenient gripping groove 10 opened at the end of the two metal clamping rods 7 at their respective ends, and a protruding vertical plate 8 fixedly connected to the end of the two hollow side frames 4 at their respective ends, with the two protruding vertical plates 8 arranged alternately vertically.

[0018] Please see Figures 2-3 Two guide ropes 9 are fixedly connected between the two internal upright plates 5. The two guide ropes 9 pass through the left and right sides of the first-level corrugated dustproof plate 6. The corresponding metal rods 7 and the protruding upright plates 8 are magnetically connected. The second-level corrugated dustproof plate 11 and the first-level corrugated dustproof plate 6 are arranged in an alternating manner.

[0019] By setting a guide rope 9 that can extend with pulling, it provides movement guidance. The guide rope 9 passes through the primary corrugated dustproof plate 6, further limiting its sway and preventing dust leakage due to vibration. When the entire strip air vent frame 1 needs to be disassembled for deep cleaning or maintenance, the secondary corrugated dustproof plate 11 is first pulled outward through the easy-grip groove 10, in the same manner as the primary corrugated dustproof plate 6, so that it completely covers the outer side of the primary corrugated dustproof plate 6. At this time, the secondary corrugated dustproof plate 11 forms a receiving layer, which can intercept the dust attached to the surface of the primary corrugated dustproof plate 6.

[0020] Please see Figures 2-4 The lower end of the hollow side frame 4 is fixedly connected to a removable connecting plate layer 17. The left and right ends of the removable connecting plate layer 17 are symmetrically provided with side inner grooves 12. The upper end of the removable connecting plate layer 17 is symmetrically provided with connecting grooves 14 on the left and right sides. The side inner grooves 12 and connecting grooves 14 on the same side are connected to each other. The inner end of the side inner groove 12 is slidably connected with a protruding follower plate 13. The upper end of the protruding follower plate 13 is fixedly connected with a vertical hand grip plate 15 extending outside the connecting groove 14. The ends of the two vertical hand grip plates 15 that are far apart from each other are fixedly connected with a pressure spring 16. The pressure spring 16 and the inner side wall of the connecting groove 14 are connected to each other. The left and right inner walls of the side auxiliary seat 3 are symmetrically provided with slots. The two slots and the corresponding protruding follower plate 13 are connected to each other.

[0021] Quick assembly and disassembly are achieved by setting a snap-fit ​​structure for the easy-to-disassemble connecting plate layer 17. Hold the vertical hand grip plate 15 that extends outside the connecting groove 14, press the compression spring 16 inward, and drive the protruding follow-up clamping plate 13 to slide inward along the side inner groove 12, disengaging from the clamping groove of the side auxiliary seat 3. At this time, the hollow side frame 4 and the strip-shaped air vent outer frame 1 can be lifted directly upward to complete the disassembly. No tools are required for the operation.

[0022] The working principle of this utility model is as follows: This solution forms a double-layer dustproof structure through a primary corrugated dustproof plate 6 and a secondary corrugated dustproof plate 11. When the air conditioner is not used for a long time, the primary corrugated dustproof plate 6 can be gripped and pulled outward by the easy-grip groove 10 provided on the metal lever 7. The guide rope 9 can extend with the pull, providing movement guidance. The guide rope 9 passes through the primary corrugated dustproof plate 6, further limiting its shaking and preventing dust leakage due to vibration until the primary corrugated dustproof plate 6 completely covers the inner side of the air guide grille 2. At this time, the primary corrugated dustproof plate 6 forms a closed barrier, blocking external dust from entering the air outlet from the air duct, and preventing dust from accumulating in the air guide grille 2 and air duct after long-term disuse. When it is necessary to disassemble the entire strip air outlet frame 1 for deep cleaning or maintenance, the secondary corrugated dustproof plate 11 is first removed through the easy-grip groove 10. Pull it outwards, following the same principle as the first-level corrugated dustproof board 6, so that it completely covers the outer side of the first-level corrugated dustproof board 6. At this time, the second-level corrugated dustproof board 11 forms a receiving layer, which can intercept the dust attached to the surface of the first-level corrugated dustproof board 6, preventing the dust from falling directly into the room during the disassembly process. Before cleaning, quick installation and removal are achieved through the snap-fit ​​structure of the easy-to-disassemble connecting plate layer 17. Hold the vertical hand grip plate 15 that extends to the outside of the connecting groove 14, press the compression pressure spring 16 inwards, and drive the protruding follower plate 13 to slide inwards along the inner groove 12 of the side, disengaging from the slot of the side auxiliary seat 3. At this time, the hollow side frame 4 and the strip-shaped air outlet outer frame 1 can be lifted directly upwards to complete the disassembly. No tools are required for the operation, and the entire operation can be completed without professional tools. This not only ensures the air outlet efficiency for long-term use, but also completely solves the problems of dust accumulation during shutdown and secondary pollution during disassembly.

[0023] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
