Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and more specifically, it relates to a central air conditioning air supply regulation device. Background Technology

[0002] Central air conditioning, as the air conditioning hub of a building, creates a comfortable environment by regulating indoor temperature. Its indoor section has air vents connected to the outdoor unit. To achieve a balance between aesthetics and functionality, the air vents are typically equipped with elegantly designed panels and built-in airflow guiding structures to optimize airflow distribution and ensure efficient and uniform air delivery.

[0003] The existing central air conditioning air supply system still has the following problems when in use: While existing air outlets are highly efficient in terms of airflow output, they generally lack an integrated effective dust filtration structure. Their front panels easily accumulate dust over long-term use, affecting aesthetics and hygiene. Furthermore, the panels are often secured with screws at multiple points, making disassembly and assembly cumbersome. This not only requires tools but also increases the risk of damage during disassembly, significantly hindering daily cleaning and maintenance, thus reducing users' willingness and frequency of self-cleaning. Moreover, when the central air conditioning system is off, gaps between the air supply unit and the ductwork, or incompletely sealed pipe interfaces, can become entry points for small insects. After insects inhabit and reproduce inside the unit, their remains and excrement are difficult to remove naturally, gradually accumulating and decomposing, causing microbial growth, and subsequently spreading into the room through re-airflow, becoming a potential health hazard and source of air pollution.

[0004] In view of this, we propose a central air conditioning air supply regulation device. Utility Model Content

[0005] (a) Technical problems to be solved In view of the problems existing in the prior art, the present invention provides a central air conditioning air supply regulation device to solve the technical problems mentioned in the background art.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a central air conditioning air supply regulating device, comprising a housing, a docking frame inserted into the housing, a support frame fixed to the inner wall of the housing, a filter screen abutting between the docking frame and the support ring, air guide plates evenly distributed on the docking frame, through grooves provided at each of the four corners of the docking frame, a fixing column fixed in the through groove of the docking frame, a limit hook slidably connected to the fixing column, a spring fixed between the limit hook and the docking frame, a limit groove provided at each of the four corners of the housing, the limit hook engaging with the limit groove, and a shielding structure provided on the docking frame.

[0007] The present invention is further configured such that two adjacent limiting hooks are jointly fixedly connected to a connecting rod, and the connecting rod is fixedly connected to a handle.

[0008] The present invention is further configured such that a cleaning component is slidably connected to the equally spaced air guide plates.

[0009] The present invention is further configured such that the shielding structure includes a fixed shell, the fixed shell is fixedly connected to one side of the docking frame, and connecting discs are fixedly connected to both ends of the fixed shell.

[0010] The present invention is further configured such that the fixing shell contacts the inner wall of the docking frame, and a through groove is provided on one side of the fixing shell.

[0011] The present invention is further configured such that a rotating shaft is rotatably connected between the two connecting discs, and a filter cloth is wound around the rotating shaft. The filter cloth passes through the through groove of the fixed shell and is fixedly connected to the cleaning component.

[0012] The present invention is further configured such that a spring is fixedly connected between the rotating shaft and the docking frame.

[0013] The present invention is further configured such that the cleaning component is fixedly connected to a limiting block, the limiting block has a through hole in the middle, the docking frame is fixedly connected to a fixing plate on the side away from the fixing shell, the fixing plate is slidably connected to a limiting rod, the limiting rod is limitedly engaged with the through hole of the limiting block, the limiting rod is fixedly connected to a connecting member, and a spring is fixedly connected between the connecting member and the fixing plate.

[0014] (III) Beneficial Effects Compared with the prior art, the present invention provides a central air conditioning air supply regulation device, which has the following beneficial effects: 1. This utility model, through the linkage structure of a limiting hook, a spring, and a handle, allows users to easily release the limiting mechanism between the docking frame and the outer shell by simply squeezing the handle, enabling quick removal of the filter for cleaning or replacement. This design eliminates the need for traditional bolt fixing or complex clip operations, improving maintenance efficiency and reducing the difficulty of daily cleaning.

[0015] 2. This utility model adopts a shielding structure. When the air conditioner is turned off, the filter cloth can be unfolded by pulling the cleaning component to completely cover the internal channel of the docking frame. It is then fixed to the limiting block by a limiting rod, effectively preventing pollutants such as mosquitoes and dust from entering the air conditioner. This not only avoids internal contamination but also reduces the need for subsequent cleaning and extends the service life of the equipment.

[0016] 3. This utility model features a cleaning component that slides between itself and the air guide plate, allowing for the removal of accumulated impurities from the air guide plate surface when manually pulled. Simultaneously, a spring mechanism automatically winds up the filter cloth and resets the cleaning component, eliminating the need for an external power source. This structure ensures cleanliness of the air guide plate area and enables automatic restoration after operation, simplifying user procedures. Attached Figure Description

[0023] Please see Figure 5 and Figure 6 The shielding structure includes a fixed shell 13, which is fixedly connected to one side of the docking frame 2. Both ends of the fixed shell 13 are fixedly connected to connecting plates 14. The fixed shell 13 contacts the inner wall of the docking frame 2, and a through groove is provided on one side of the fixed shell 13. A rotating shaft 15 is rotatably connected between the two connecting plates 14. A filter cloth 16 is wound on the rotating shaft 15. The filter cloth 16 passes through the through groove of the fixed shell 13 and is fixedly connected to the cleaning component 12. A spring 17 is fixedly connected between the rotating shaft 15 and the docking frame 2. A limiting block 18 is fixedly connected to the cleaning component 12. A through hole is provided in the middle of the limiting block 18. A fixed plate 19 is fixedly connected to the side of the docking frame 2 away from the fixed shell 13. A limiting rod 20 is slidably connected to the fixed plate 19. The limiting rod 20 is limited and engaged with the through hole of the limiting block 18. A connecting component 21 is fixedly connected to the limiting rod 20. A spring 22 is fixedly connected between the connecting component 21 and the fixed plate 19.

[0024] The working principle of this utility model: When it is necessary to clean the impurities on the filter screen 4, hold the two handles 11 and move them close to each other. The handles 11 drive the two limit hooks 7 to move through the connecting rod 10. The limit hooks 7 slide along the adjacent fixed post 6, and the spring 8 is compressed. The limit hooks 7 lose their limit with the adjacent limit groove 9, thereby removing the docking frame 2 from the outer shell 1. Release the handles 11, and under the elastic force of the spring 8, the limit hooks 7 return to their original position. The docking frame 2 no longer squeezes the filter screen 4. Then, remove the filter screen 4 from the support ring 3 and complete the cleaning. After the filter screen 4 is cleaned, install the filter screen 4 back in its original position and reinstall the docking frame 2 on the outer shell 1. The limit hooks 7 re-engage with the limit groove 9.

[0025] When the central air conditioning is not in use, pull the cleaning component 12 to the right. The cleaning component 12 moves along the air guide plate 5 to clean the impurities on the air guide plate 5. The cleaning component 12 also pulls the filter cloth 16 to the right. The filter cloth 16 drives the rotating shaft 15 to rotate along the two connecting discs 14. The spring 17 is tightened. The filter cloth 16 moves against the upper and lower sides of the inner wall of the docking frame until the cleaning component 12 moves to the right side of the docking frame 2. Then lift the connecting component 21 upward. The connecting component 21 drives the limiting rod 20 to move upward. The spring 22 is compressed. Then, the limiting rod 20 is inserted into the through hole of the limiting block 18. The limiting rod 20 and the limiting block 18 cooperate to fix the position of the cleaning component 12, so that the filter cloth 16 seals the docking frame 2, thereby preventing mosquitoes from entering the central air conditioning. When the central air conditioning is put back into use, simply lift the connector 21 upwards to release the limit rod 20 from the limit block 18, so that under the elastic force of the spring 17, the rotating shaft 15 will wind up the filter cloth 16 and reset the cleaning component 12.
