Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning equipment, in particular to a central air-conditioning outlet which is automatically opened and closed by wind pressure. Background Art

[0002] Central air conditioning is a device that controls different rooms to achieve indoor air conditioning by connecting multiple terminal devices through air ducts or refrigerant pipes. It is a type of large air conditioner that uses duct air supply. One host can control multiple different rooms and introduce fresh air.

[0003] During use, the existing central air-conditioning outlet is usually turned on and off by the air-conditioning switch, but the air-conditioning outlet does not have an automatic opening and closing function. When the air-conditioning wind pressure is high, the air outlet cannot be closed in time, and the indoor temperature and humidity cannot be kept relatively stable according to the actual wind pressure changes, affecting the comfort of living or working. In addition, the direction of the central air-conditioning outlet is relatively fixed, and the wind direction cannot be adjusted according to the actual situation, affecting the comfort of use.

[0004] Therefore, it is necessary to provide a new central air-conditioning outlet with automatic opening and closing of wind pressure to solve the above technical problems. Utility Model Content

[0005] The purpose of the utility model is to provide a central air-conditioning outlet that automatically opens and closes according to wind pressure, so as to solve the problems raised in the above-mentioned background technology.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-4 As shown, a central air-conditioning outlet with automatic opening and closing of wind pressure includes a shell 1. A wind pressure sensor 2 is provided inside the shell 1. The wind pressure sensor 2 is a prior art that obtains wind pressure data by measuring the pressure change generated when the gas flows. It will not be described in detail here. One side of the shell 1 is fixedly connected to a limit frame 3. The inner wall of the limit frame 3 is slidably connected to a baffle 4. The air outlet can be opened or closed by the baffle 4. The top of the baffle 4 is fixedly connected to a pull rope 5. The pull rope 5 can drive the baffle 4 to move. A drive box 6 is provided on the top of the shell 1. The inner wall of the drive box 6 is rotated and connected to the baffle 4. It is connected to a rotating rod 7, and a winding roller 8 is fixedly connected to the outer side of the rotating rod 7. The pull rope 5 can be wound through the winding roller 8. A mounting plate 9 is fixed to the inner wall of the shell 1. The inner wall of the mounting plate 9 is rotatably connected to multiple sets of adjusting rods 10. One end of the adjusting rod 10 is fixedly connected to a diverter plate 11, and the diverter plate 11 can be driven to rotate by the adjusting rod 10. The outer side of the adjusting rod 10 is fixedly connected to a driving gear 12, and the driving gear 12 can drive the adjusting rod 10 to rotate, thereby achieving the effect of adjusting the wind direction and improving the comfort of use. The outer side of the driving gear 12 is meshed with a tooth plate 13.

[0024] A first motor 14 is installed on one side of the drive box 6, and the output end of the first motor 14 is fixedly connected to the first bevel gear 15, and the outer side of the first bevel gear 15 is meshed with the second bevel gear 16, and the second bevel gear 16 is fixed to the outer side of the rotating rod 7. The inner wall of the limit frame 3 is fixedly connected to the limit rod 17, and one side of the baffle 4 is fixedly connected to the limit plate 18. The inner wall of the limit plate 18 is slidably connected to the outer side of the limit rod 17, and a spring 19 is provided on the outer side of the limit rod 17. A fixing plate 20 is fixedly connected to one side of the drive box 6, and the bottom of the fixing plate 20 is fixedly connected to the top of the limit rod 17. Starting the first motor 14 drives the first bevel gear 15 and the second bevel gear 16 to rotate. The gear 16 rotates, driving the rotating rod 7 and the winding roller 8 to rotate, and the pull rope 5 is wound by the winding roller 8. The pull rope 5 pulls the baffle 4 to slide inside the limit frame 3, causing the limit plate 18 to slide outside the limit rod 17, causing the spring 19 to contract, opening the air outlet for air discharge, and monitoring the wind pressure at the air outlet through the wind pressure sensor 2. When the wind pressure exceeds the set value, the wind pressure sensor 2 controls the first motor 14 to start, causing the first motor 14 to rotate in the opposite direction, loosening the pull rope 5. At this time, the spring 19 resets and drives the limit plate 18 to slide outside the limit rod 17, causing the baffle 4 to block the air outlet, thereby achieving the effect of opening or closing the air outlet according to the wind pressure.

[0025] The inner wall of the shell 1 is fixedly connected to a fixing frame 21, and a second motor 22 is installed on the top of the fixing frame 21. The output end of the second motor 22 is fixedly connected to a threaded rod 23, and a threaded sleeve 24 is fixedly connected to one side of the tooth plate 13. The inner wall of the threaded sleeve 24 is threadedly connected to the outer side of the threaded rod 23, and the outer side of the tooth plate 13 is fixedly connected to a connecting plate 25. The outer side of the connecting plate 25 is slidingly connected to the inner wall of the fixing frame 21. Starting the second motor 22 drives the threaded rod 23 to rotate, and the tooth plate 13 is driven to move through the threaded sleeve 24, so that the driving gear 12 drives the adjusting rod 10 to rotate, and the diverter plate 11 is rotated. The angle of the diverter plate 11 changes, thereby adjusting the wind direction. An air inlet pipe 26 is provided on one side of the shell 1, and a guide wheel 27 for protecting the pull rope 5 is provided on one side of the drive box 6.

[0026] Working principle: When the device is in use, the first motor 14 is started to drive the first bevel gear 15 and the second bevel gear 16 to rotate, which drives the rotating rod 7 and the winding roller 8 to rotate, and the pull rope 5 is wound by the winding roller 8. The pull rope 5 pulls the baffle 4 to slide inside the limit frame 3, so that the limit plate 18 slides outside the limit rod 17, so that the spring 19 contracts, and the air outlet is opened for air discharge. The wind pressure at the air outlet is monitored by the wind pressure sensor 2. When the wind pressure exceeds the set value, the wind pressure sensor 2 controls the first motor 14 to start, so that the second motor 14 is opened. A motor 14 rotates in the opposite direction to loosen the pull rope 5. At this time, the spring 19 resets and drives the limit plate 18 to slide on the outside of the limit rod 17, so that the baffle 4 blocks the air outlet, thereby achieving the effect of opening or closing the air outlet according to the wind pressure. The second motor 22 is started to drive the threaded rod 23 to rotate, and the tooth plate 13 is driven to move through the threaded sleeve 24, so that the driving gear 12 drives the adjusting rod 10 to rotate, and the diverter plate 11 is rotated. The angle of the diverter plate 11 changes, thereby adjusting the wind direction and improving the comfort of use.
