Description

Technical Field

[0001] This utility model relates to the field of heating, ventilation and air conditioning (HVAC), and in particular to a lever-type equalization regulating device for multi-split air conditioners. Background Technology

[0002] Multi-split air conditioning (VRF) is a mainstream form of central air conditioning, with its core advantages being flexible adjustment and energy efficiency. With increasing demands for building intelligence and green energy conservation, it is widely used in shopping malls, office buildings, and other similar locations. However, it often relies on traditional control devices, which suffer from feedback delays and require effective control of airflow and force to avoid energy waste.

[0003] However, some existing multi-split air conditioner lever-type adjustable devices are usually adjusted by lever arm during use. However, they do not take into account that the lever arm cannot be adjusted, and the adjustment range is fixed, which may result in failure to meet different needs.

[0004] Therefore, a multi-split air conditioner lever-type energy regulating device is proposed to address the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a multi-split air conditioner lever-type energy regulating device, which aims to improve the energy waste caused by the inability to change the wind power output according to actual needs in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A multi-split air conditioner lever-type energy-saving adjustment device includes a ventilation duct with a lever structure inside. The lever structure comprises a second rotating shaft, a first telescopic rod, a second telescopic rod, and a first sliding block. The sleeve ends of the first and second telescopic rods are rotatably connected to the second rotating shaft. The bottom end of the second rotating shaft is rotatably connected to the second sliding block. The extended end of the first telescopic rod is rotatably connected to the first rotating shaft. The first rotating shaft is rotatably connected to a U-shaped clamp. The U-shaped clamp is fixedly connected to a wind shield. The extended end of the second telescopic rod is rotatably connected to a fixed rod. The top surface of the first sliding block has a fixing groove for the fixed rod to rotate. As a further description of the above technical solution: The outdoor unit of the multi-split air conditioner is connected to the ventilation duct through a pipe structure, which includes exhaust pipe one, exhaust pipe two, exhaust hole one, and exhaust hole two. Exhaust pipe one is inserted into exhaust hole one, and exhaust pipe two is inserted into exhaust hole two. As a further description of the above technical solution: An electric push rod is fixedly connected to the bottom of the ventilation duct, and the extended end of the electric push rod is fixedly connected to the sliding block. As a further description of the above technical solution: A motor is installed inside the ventilation duct, and the motor drives a threaded rod. The threaded rod passes through a fixed block that is fixedly connected to the ventilation duct and is threadedly connected to a sliding block. As a further description of the above technical solution: Multi-split air conditioner outdoor units are equipped with internal fans; As a further description of the above technical solution: The outer casing of the multi-split air conditioner outdoor unit is provided with several honeycomb-shaped heat dissipation holes; As a further description of the above technical solution: The rotating shaft is rotatably connected to a limiting ring. As a further description of the above technical solution: The ventilation duct is connected to two outlet pipes, namely, outlet pipe one and outlet pipe two, and the outlet pipe one and outlet pipe two are provided with ventilation openings.

[0007] This utility model has the following beneficial effects: 1. In this utility model, the fan in the outdoor unit of a multi-split air conditioner, the honeycomb heat dissipation holes, and the lever structure in the ventilation duct achieve wind force regulation. An electric push rod drives a sliding block, which in turn drives a fixed rod, a telescopic rod, another telescopic rod, a U-shaped clamp, and a wind shield, thus blocking the ductwork where wind transmission is unnecessary. A motor generates driving force to rotate the threaded rod, causing a change in the position of the rotating shaft fixedly connected to the sliding block, thereby altering the lever structure. This allows for immediate adjustment to meet different needs, reducing unnecessary energy loss. Attached Figure Description

[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0011] Reference Figures 1 to 4 This utility model provides an embodiment of a multi-unit air conditioner lever-type adjustable device, including a ventilation duct. The ventilation duct has a lever structure inside, which includes a second rotating shaft 16, a first telescopic rod 12, and a second telescopic rod 19. The second rotating shaft 16 is used to stabilize the structure's operation. The first telescopic rod 12 and the second telescopic rod 19 assist the structure's operation. The sleeve ends of the first telescopic rod 12 and the second telescopic rod 19 are rotatably connected to the second rotating shaft 16. The bottom end of the second rotating shaft 16 is rotatably connected to a second sliding block 23, which assists the movement of the second rotating shaft 16. The second rotating shaft 16 is rotatably connected to a limit ring 18 to prevent the structure from detaching. The extended end of the first telescopic rod 12 is rotatably connected to a first rotating shaft 11, which assists the structure's operation. The first rotating shaft 11 is rotatably connected to a U-shaped clamp 10 to maintain the overall structure. For stability, a U-shaped clamp 10 is fixedly connected to a wind shield 9, which controls the airflow. A telescopic rod 29 is rotatably connected to a fixed rod 20 at its extended end, which stabilizes the structure. A fixed groove 21 for the fixed rod 20 to rotate is provided on the top surface of a sliding block 22, which assists the structure in rotating. The sliding block 22 helps the structure to move along the ventilation duct under the thrust of the electric push rod 17. The multi-split air conditioner outdoor unit is connected to the ventilation duct through a pipe structure, which transmits airflow. The pipe structure includes an exhaust pipe 3, an exhaust pipe 4, an exhaust hole 6, and an exhaust hole 8. An exhaust pipe 3 is inserted into an exhaust hole 6, and an exhaust pipe 4 is inserted into an exhaust hole 8. An air outlet 5 and an air outlet 7 are inserted at both ends of the ventilation duct. The air outlet 5 has a ventilation opening, which is used to transmit internal airflow.

[0012] Reference Figure 1 and Figure 4 An electric push rod 17 is fixedly connected to the bottom of the ventilation duct, providing power. The extended end of the electric push rod 17 is fixedly connected to a sliding block 22, which controls the position change of the structure. The multi-split air conditioner outdoor unit is equipped with a fan 1, and the outer casing of the multi-split air conditioner outdoor unit is equipped with several honeycomb-shaped heat dissipation holes 2, which assist in heat dissipation.

[0013] Working principle: The outdoor unit B of the external air conditioner dissipates heat through the internal fan 1 and honeycomb heat dissipation holes 2. The air energy is then transferred to the ventilation duct through the exhaust pipes 3 and 4, which pass through the exhaust holes 6 and 4 respectively. By adjusting the working efficiency of the electric push rod 17, the electric push rod 17 drives the sliding block 22. The sliding block 22 is forced to move the fixed rod 20. The displacement of the fixed rod 20 causes the rotatably connected telescopic rod 19 to move. The telescopic rod 19 transmits the force to the telescopic rod 12 through the rotating shaft 16. The telescopic rod 12 is forced to pull the rotating shaft 11 on the U-shaped clamp, thereby causing the wind shield 9 to shift. When the shift space can accommodate the air outlet 5, the air vent on the air outlet 5 simultaneously enters the ventilation duct. By controlling the shift position of the wind shield 9 by the control lever, the air volume is controlled, thereby reducing unnecessary energy waste.

[0014] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
