[0041] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the technical solution of the present invention is clearly and completely described below in combination with specific embodiments and with reference to the accompanying drawings. Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0042] like Figure 1 As shown, the present embodiment provides an automatic clothes drying rack, comprising a main body 1 fixed to a roof, a lifting mechanism 2 being fixedly provided on the main body 1, a clothes drying mechanism 3 being fixed at the lower end of the lifting mechanism 2, a vortex fan 4 for discharging air from below being provided on the clothes drying mechanism 3, a humidity sensor 5 and a clothes hanger 6 capable of rotating around the outer circumference of the clothes drying mechanism 3 being provided on the lower surface of the clothes drying mechanism 3, the humidity sensor 5 being capable of detecting the dryness and wetness of clothes within its detection range; in specific use, those skilled in the art can detect the dryness and wetness of clothes based on the clothes drying rack provided by the present embodiment, and control the actions of the vortex fan 4 and the clothes hanger 6. Specifically, if the clothes need to be dried so as to dry them quickly, when the humidity sensor 5 detects that the humidity of the clothes reaches the drying requirement, the vortex fan 4 is automatically turned off to save energy; if the drying condition is not reached, the vortex fan 4 is turned on or kept on working, and at the same time, the position of the clothes hanger 6 can be adjusted so that the undried clothes are in a well-lit position.

[0043] When it is necessary to implement the above functions, those skilled in the art can configure corresponding control programs and sensors as needed. Of course, they can also directly rely on manual control of the movement of the clothes drying rack to move the target clothes into the detection range of the humidity sensor 5, and then control the humidity sensor 5 for detection, and manually adjust the movement of the vortex fan 4 and the clothes hanger 6 according to the monitoring results; when it is expected that the clothes drying rack automatically completes the above work, ultrasonic sensors, infrared diffuse reflection sensors and other position sensors can be set at appropriate positions in the monitoring range of the humidity sensor 5, and the pneumatic humidity sensor 5 can be used when the presence of clothes is detected. A weight sensor can also be set on the clothes hanger 6 to determine whether there are clothes on the clothes hanger 6 according to the weight of the hanging objects, and the dryness and humidity of the clothes hanger 6 with clothes hanging thereon can be detected. At the same time, a light intensity sensor can be added to monitor the light intensity at various positions near the clothes drying rack, and the undried clothes can be moved to a position with better light intensity. The above specific sensor setting positions, signal communication and control methods can all be implemented by existing technologies or simple variations of existing technologies, and will not be repeated in this embodiment.

[0044] This embodiment realizes the detection of the dryness and humidity of clothes through the humidity sensor 5, so that the working state of the vortex fan 4 can be automatically controlled, unnecessary energy consumption can be reduced, the user can be reminded to collect clothes in time, and the clothes can be quickly dried. It is easy to use and saves energy and electricity.

[0045] Combination Figure 2 The lifting mechanism 2 includes two lifting frames 21 fixed at both ends of the body 1 and a lifting unit 22 for driving the lifting frames 21 on both sides to lift synchronously. The lifting unit 22 is fixed between the lifting frames 21 on both sides and is wound with traction ropes 23 extending to the lifting frames 21 on both sides respectively. The lifting frame 21 includes a first flange 211 fixed on the body 1, and a rope pulley (not shown) is fixed on the first flange 211. Second flanges 212 are fixedly provided at both ends of the upper surface of the clothes drying mechanism 3, and the end of the traction rope 23 is passed around the rope pulley and fixed on the second flange 212 in the vertical direction, so that the height of the clothes drying mechanism 3 relative to the body 1 can be changed by the lifting unit 22 to retract and release the traction rope 23, so as to facilitate the taking and placing of clothes.

[0046] Refer to Figure 1 The lifting frame 21 also includes a plurality of scissor-type telescopic mechanisms 213 uniformly arranged along the circumference of the first flange 211, and the two ends of the scissor-type telescopic mechanisms 213 are respectively hingedly fixed to the first flange 211 and the second flange 212 by pins or bolts; thereby preventing the clothes drying mechanism 3 from shaking due to uneven force during the lifting and adjusting of the position of the clothes hanger 6, thereby improving stability.

[0047] Combination Figure 3 and Figure 4The lifting unit 22 includes a shell 221 fixed below the body 1 and between the lifting frames 21 on both sides. A motor box 222 is fixed inside the shell 221. The output shaft 223 of the motor box 222 is fixedly connected to a worm 224 in the horizontal direction. The worm 224 is meshed with a worm wheel 225. The worm wheel 225 is sleeved on a fixed shaft 226. The two ends of the fixed shaft 226 are respectively fixedly matched with the upper and lower surfaces of the shell 221. A first gear 227 is sleeved on the bottom of the fixed shaft 226. The worm wheel 225 is locked with the first gear 227 along the fixed shaft 226 through a self-locking unit 24 sleeved on the fixed shaft 226. Circumferentially fixed, the first gear 227 is meshed with the second gear 228 on both sides, the second gear 228 is coaxially fixed with a reel 229, and the traction ropes 23 on both sides are respectively fixed and wound on the reels 229 on both sides; thereby, the power output by the motor box 222 can drive the worm 224 to rotate, drive the worm wheel 225 to rotate in the horizontal plane, and transmit the rotation to the first gear 227 below, and the first gear 227 drives the second gears 228 on both sides to rotate synchronously, so as to realize the synchronous retraction and release of the traction rope 23 on the reel 229, so that the two sides of the clothes drying mechanism 3 can be raised and lowered synchronously to maintain balance.

[0048] In this embodiment, the fixed shaft 226 serves to strengthen the structural strength of the shell 221 and provides a rotating shaft for the worm gear 225 and the first gear 227. However, the worm gear 225 is driven by the worm 224 and transmits power to the first gear 227 through the self-locking unit 24. While ensuring that the power worm gear 225 is coaxial with the first gear 227 and effectively cooperates with the self-locking unit 24, it is not strictly required that the fixed shaft 226 that is fixed to the upper and lower surfaces of the shell 221 serve as a rotating shaft.

[0049] A guide wheel 231 is also provided next to the reel 229, and the traction rope 23 contacts the guide wheel 231 to guide the traction rope 23, and the rotating shafts of the second gear 228 and the guide wheel 231 are fixed in the shell 221 along the vertical direction, and the motor box 222 drives the output shaft 223 to rotate through a motor (not shown in the figure), and the motor and the output shaft 223 are fixed coaxially. In order to increase the driving force in this embodiment, two motors are provided in the motor box 222, and the output shafts of the two motors are respectively fixedly connected to a driving gear (not shown in the figure) located outside the motor box, and a transmission gear (not shown in the figure) meshing with the two driving gears is fixed on the output shaft 223, so that the output shaft 223 is synchronously driven by the two motors to rotate to provide lifting power. Those skilled in the art can also set more motors for driving according to this idea.

[0050] refer to Figure 4The self-locking unit 24 includes a first self-locking ring 241, a second self-locking ring 242, a fixing ring 243 and a tightening ring 244 which are coaxially arranged in sequence. The first self-locking ring 241 is fixedly matched with the worm wheel 225 through an axial screw 245. Figure 5-Figure 9 The first self-locking ring 241 and the second self-locking ring 242 are in contact with each other on one side, respectively, and a protrusion 246 and a groove 247 for accommodating the protrusion 246 are radially arranged. The radial section of the groove 247 along the fixed shaft 226 includes at least two inclined reducers 2471. The reducer 2471 has a larger diameter at one end close to the outer surface of the second self-locking ring 242. The first gear 227 includes a sleeve 2271 sleeved on the fixed shaft 226. The second self-locking ring 242 and the sleeve 2271 are locked in the circumferential direction by a keyway structure 2272, so that the sleeve 2271 can rotate synchronously with the second self-locking ring 242.

[0051] In this embodiment, the circumferential fixation of the first self-locking ring 241 and the second self-locking ring 242 is achieved by the cooperation of the protrusion 246 and the groove 247. The first self-locking ring 241 is driven to rotate by the worm gear 225, and the second self-locking ring 242 rotates following the first self-locking ring 241. The sleeve 2271 and the second self-locking ring 242 are locked by the keyway structure 2272, so that the sleeve 2271 can rotate following the second self-locking ring 242, thereby achieving complete power transmission, and finally the motor box 222 drives the first gear 227 to rotate. The first self-locking ring 241 and the first gear 227 are respectively provided with bearings (not shown) fixedly matched with the fixed shaft 226.

[0052] This embodiment uses a worm gear structure for driving, and the motor output shaft 223 is difficult to rotate when not driven by the motor, so the driving structure itself can achieve position locking; therefore, it can be used normally and prevent the clothes drying mechanism 3 from accidentally falling.

[0053] In order to further improve the locking stability, this embodiment uses the cooperation of the second self-locking ring 242 and the fixing ring 243 to perform auxiliary locking. Figure 4 The fixing ring 243 and the tightening ring 244 are respectively fixedly matched with the two sides of the shell 221, so as to be locked in the axial direction. The second self-locking ring 242 is a truncated cone structure with a larger diameter on the side close to the first bearing 227. The inner circumference of the fixing ring 242 is adaptively matched with the outer circumference of the second self-locking ring 242. A self-locking spring 248 is sleeved between the second self-locking ring 242 and the tightening ring 243 and is located on the outside of the sleeve 2271. In the static state, the self-locking spring 248 presses the second self-locking ring 242 tightly against the inner circumference of the fixing ring 243. When the worm gear 225 rotates, the protrusion 246 contacts the reducing section 2471 of the groove 247 to drive the second self-locking ring 242 to separate axially relative to the fixing ring 243.

[0054] refer to Figure 6 , in a stationary state, the friction between the second self-locking ring 242 and the fixed ring 243 is used to lock the second self-locking ring 242 to prevent accidental rotation; Figure 7 During rotation, due to the existence of this friction force, the second self-locking ring 242 will be prevented from rotating, so the first self-locking ring 241 will rotate independently, so that the protrusion 246 and the reducing section 2471 of the groove 247 will slide relative to each other, thereby pressing the second self-locking ring 242 axially downward to leave the fixing ring 243. After the second self-locking ring 242 is separated from the fixing ring 243, the friction force disappears, and the second self-locking ring 242 can rotate with the first self-locking ring 241. During normal rotation, this friction force will not exist, so the self-locking of the lifting is conveniently realized without affecting the normal drive.

[0055] In this embodiment, the protrusion 246 is disposed on the first self-locking ring 241 , the groove 247 is disposed on the second self-locking ring 242 , and two protrusions 246 and two grooves 247 are evenly disposed along the circumferential direction, respectively.

[0056] After the second self-locking ring 242 is separated from the fixing ring 243, the second self-locking ring 242 can rotate. Therefore, under normal circumstances, the groove 247 may only include the diameter-reducing section 2471. Figure 6 V-shaped groove as shown; however, if the clothes hung by the clothes drying mechanism 3 are too heavy or the movement resistance increases due to other reasons, the first self-locking ring 241 may have left the second self-locking ring 242 before the second self-locking ring 242 has time to move. In order to prevent the first self-locking ring 241 from being completely separated from the second self-locking ring 242, the present application also provides other embodiments, such as Figure 8 As shown, the V-shaped groove bottom is set as the diameter reducing section 2471, and the upper two side surfaces of the diameter reducing section 2471 are set vertically; Fig. 9 In the embodiment shown, the bottom of the reducing section 2471 is set as a horizontal plane, and the end of the protrusion 246 is a truncated cone. When the protrusion 246 contacts the bottom of the groove 247, it does not contact the hypotenuse of the reducing section 2471, so that the first self-locking ring 241 can rotate without resistance first, and then the protrusion 246 contacts the reducing section 2471 to drive the second self-locking ring 242 to be compressed along the axis; based on the above embodiment, those skilled in the art can adaptively adjust the specific structure of the groove to achieve the axial movement and circumferential rotation of the second self-locking ring 242. In addition, since the second self-locking ring 242 and the shaft sleeve 2271 are matched through the keyway structure 2272, a limiting mechanism can also be set on the groove of the second self-locking ring 242 to limit the distance of the second self-locking ring 242 along the axial compression to prevent the protrusion 246 from being out of match with the groove 247.
