When the air vent cannot be pulled due to other reasons, the current method will continue to control the motor rotation because the controller does not collect enough pulses, causing damage to the air vent or other facilities. Utility Model Content

DETAILED DESCRIPTION
[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0021] See also Figure 1-3 The utility model provides a technical solution: an air outlet control device, including an apparatus bottom plate 1, a device box 2 is fixedly connected to the middle of the upper surface of the apparatus bottom plate 1, a motor 3 and a reducer 4 are fixedly connected inside the apparatus box 2, an output shaft of the motor 3 is fixedly connected to the outer end of the input shaft of the reducer 4, the outer end of the output shaft of the reducer 4 can rotatably pass through the side surface of the apparatus box 2 and extend outward, a rotating tube 6 is laterally fixedly connected to the outer end surface of the output shaft of the reducer 4, a support ring 5 is rotatably connected to the outer surface of the other end of the rotating tube 6, the bottom end of the support ring 5 is fixedly connected to the upper surface of the apparatus bottom plate 1, and an air outlet opening rope 7 and an air outlet closing rope 8 are wound around the outer surface of the rotating tube 6;
[0022] An apparatus frame 9 is vertically fixedly connected to the upper surface of the apparatus base plate 1 and located at the rear side of the rotating tube 6, and two mounting seats 10 are fixedly connected to the top of the apparatus frame 9. An air outlet opening pulley 11 and an air outlet closing pulley 12 corresponding to the air outlet opening pull rope 7 and the air outlet closing pull rope 8 are rotatably connected inside the two mounting seats 10, and the other ends of the air outlet opening pull rope 7 and the air outlet closing pull rope 8 are respectively passed around the air outlet opening pulley 11 and the air outlet closing pull rope 12 and are fixedly connected to the air outlet structure.
[0023] The top of the device box 2 is fixedly connected with a controller 13, and the controller 13 and the motor 3 are connected via a wiring harness signal.
[0024] The controller 13 is internally provided with a power supply module 16 , a 4G communication module 17 , a motor drive module 18 , a key detection module 19 , a Hall detection module 20 and a current detection module 21 .
[0025] The connection harness includes motor control wires and Hall acquisition wires.
[0026] The directions in which the air outlet opening rope 7 and the air outlet closing rope 8 are wound on the rotating tube 6 are opposite.
[0027] In this embodiment, the device is provided with a current detection module 21 inside the controller 13. Compared with the current control logic, when the device is in the process of controlling the opening and closing of the air outlet, if the damper opening angle is set but the operation does not meet the opening requirements, the current passing through the motor 3 will be detected by the current detection module 21. If the current is within a safe range, the motor 3 will be controlled again to start controlling the opening and closing of the damper. If the motor 3 cannot rotate smoothly due to external reasons, causing the current to exceed the safe range, an error will be directly reported and the operation of the motor 3 will be stopped, thereby providing better protection for the motor and other equipment.
[0028] After the motor 3 is started, the rotation of its output shaft can drive the input shaft of the reducer 4 to rotate, and then the output shaft of the reducer drives the rotating tube 6 to rotate, which can drive the opening air outlet pull rope 7 and the closing air outlet pull rope 8 wound on the surface of the rotating tube 6 to move. Since the two are wound in opposite directions on the outer surface of the rotating tube 6, the two will perform two actions of retraction and extension. The other ends of the two use the opening air outlet pulley 11 and the closing air outlet pulley 12 as fulcrums to drive the damper structure to operate to realize the opening and closing of the damper structure.
[0029] Furthermore, a plurality of mounting blocks 15 are fixedly connected to the bottom end of the device base plate 1 .
[0030] In this embodiment, the mounting block 15 is used to fix the device.
[0031] The workflow of this utility model:
[0032] S1: The user sends an opening setting command through the mobile phone, which is transmitted to the device through the operator network. The device determines whether it needs to control the motor 3 to rotate. If not, it directly completes the exit work;
[0033] S2: If it is necessary to control the operation of the motor 3, the opening difference is calculated, and the forward or reverse rotation of the motor 3 is determined by the opening difference;
[0034] S3: The motor 3 outputs a Hall signal every time it rotates 0.5 turns. The controller 13 recalculates the opening difference every time it detects a Hall signal. When the opening difference is 0, the motor 3 stops rotating and then exits.
[0035] S4: The controller 13 detects the current of the motor 3 when controlling the operation of the motor 3. When the venting structure is abnormal and causes the motor 3 to be blocked, the current increases. When the detected current is greater than the safety current, an error is reported, and then the motor 3 is controlled to stop rotating.
[0036] Working principle and use process of the utility model: After the utility model is installed, the device is provided with a current detection module 21 inside the controller 13. Compared with the current control logic, when the device is in the process of controlling the opening and closing of the air outlet, if the air door opening angle is set but the operation does not meet the opening requirements, the current passing through the motor 3 will be detected by the current detection module 21. If the current is within the safe range, the motor 3 will be controlled again to start the opening and closing of the air door. If the motor 3 cannot rotate smoothly due to external reasons, resulting in the current exceeding the safe range, the error will be directly reported and the operation of the motor 3 will be stopped, thereby providing better protection for the motor and other equipment.
[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
