[0045] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0046] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it will not be further defined and explained in subsequent figures.

[0047] In the description of this utility model, it should be noted that the terms "upper," "lower," "front," "rear," "left," "right," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Similarly, "first" and "second" are only for ease of understanding and have no other directional meaning, and cannot be considered as limitations on this utility model.

[0048] like Figure 1 , 6 As shown, the slow-descent escape device in the electric clothes drying rack includes a base plate 100 and a winch 200, a slow-descent device 300, and a container 400 for accommodating a waist belt 460, which are sequentially installed on the base plate 100.

[0049] like Figure 2-8 As shown, the wire rope 210 extending from the winch 200 passes through the descent device 300 and its internal structure to provide a slow descent function before being fixed to the belt connector 470. The remaining wire rope 210 is stored in the winch 200 when not in use. The wire rope 210, as a key component of the winch 200, first passes through the descent device 300, utilizing its ingenious internal structure to achieve a slow descent function, and then is fixed to the belt connector 470. When not in use, excess wire rope 210 is neatly stored in the winch 200 to avoid tangling.

[0050] like Figure 2-8 As shown in Figure 12, the winch 200 includes a first disc body 220 and a second disc body 230, and the first disc body 220 has a circular cavity 221 in the middle. Figure 2-5 As shown, a circular cam is mounted on the connecting portion 120 of the base plate 100, and is located at the center of the second disc body 230. A rotary connection structure is provided between the circular cavity 221 of the first disc body 220 and the circular cam. In this embodiment, the circular cam is a raised portion on the base plate, which forms a corresponding circular recess 500 on the back side of the base plate.

[0051] like Figure 4 , 6 As shown in Figure 7, a descent control device 310 is also provided on the base plate 100. A traction rope 320 extends from the descent control device 310 and is detachably connected to the winch 200. When the winch 200 separates from the circular cam, the traction rope 320 can slow down the speed at which the winch 200 falls due to its own weight. The base plate 100 is additionally equipped with a descent control device 310, and the traction rope 320 extending from the descent control device 310 is detachably connected to the winch 200. In the event of an emergency, the traction rope 320 is activated immediately the moment the winch 200 separates from the circular cam, effectively slowing down the speed at which the winch 200 falls due to its own weight, buying valuable escape time for the user, and comprehensively protecting home safety.

[0052] The rotating connection structure utilizes the pulling force of the steel wire rope by the belt 460° to twist the winch, allowing it to detach from the clothes drying rack's main unit during use. This facilitates the release of the steel wire rope during subsequent, gradual descent and escape operations, and also prevents damage to the clothes drying rack's main unit from continuous gravity. Furthermore, the slow-descent traction device 310 ensures the winch 200 descends slowly, preventing excessively rapid descent that could cause harm to people or the home environment.

[0053] like Figure 8 As shown, the outer end of the traction rope 320 passes through the center of the circular convex disk and connects to the center of the circular cavity 221 of the first disk body 220. Figure 6 , 9 As shown in Figure -11, the descent control device 310 consists of a housing 311, a coil spring 312 installed inside the housing 311, and a traction rope 320, wherein the inner end of the traction rope 320 is connected to the coil spring 312. Preferably, the housing 311 of the descent control device includes an upper plate a and a lower support b, the lower support b being provided with a winding post, and the coil spring 312 is wound around the winding post.

[0054] Furthermore, such as Figure 5 , 7 As shown, the base plate 100 of the mounting housing 311 has a through hole g. The traction rope 320 passes through the through hole g and connects to the center of the circular convex plate 500 from the back of the base plate 100. This is mainly to allow the traction rope 320 to pass through the through hole g and cooperate with the winch 200. The four screw posts are used to cooperate with the upper plate of the housing 311 for fixing. There is a coil spring 312 fixing post in the middle of the inner cavity. There is a notch on both the outer shell and the inner cavity, through which the traction rope 320 can pass to the position of the through hole g.

[0055] like Figure 4 , 5As shown in Figures 7 and 12, the bottom of the circular cavity 221 is provided with two connecting posts f, and the upper end of the connecting posts f is provided with a mushroom head e. The circular convex disk 500 is provided with two arc-shaped grooves 510, and the starting end of the arc-shaped grooves 510 is provided with a hole 520 for the mushroom head e to enter. The bottom of the cavity 221, the two arc-shaped grooves 510 and the hole 520 on the circular convex disk 500 form an ingenious structure. The mushroom head e is inserted into the arc-shaped groove 510 through the hole 520. This design not only ensures a stable connection between the two, but also allows the convex disk 500 to move relative to the cavity 221 along an arc-shaped trajectory.

[0056] Priority, such as Figure 3-4 As shown, the descent device 300 is equipped with a first pulley 330 and a second pulley 340. The wire rope 210, drawn from the winch 200, passes through the first pulley 330 and enters the interior of the descent device 300. The wire rope 210, drawn from the descent device 300, passes through the second pulley 340 and connects to the belt connector 470. The winch 200 serves as the starting point for the wire rope 210. The wire rope 210 first passes around the first pulley 330, changing the direction of force on the wire rope 210, allowing it to enter the descent device 300 more smoothly and ensuring stable operation. Subsequently, the wire rope 210 from the descent device 300 passes through the second pulley 340, and through the guiding action of the second pulley 340, it is precisely connected to the belt connector 470. This allows the entire descent system to effectively convert the human body's weight into a stable and controllable descent force during use, ensuring safe descent in emergency situations and greatly improving the practicality and reliability of the descent device 300.

[0057] like Figure 2-4 As shown, the base plate 100 includes a mounting part 110 and a connecting part 120. The winch 200, the slow-descent device 300 and the housing 400 for accommodating the waist belt 460 are disposed on the mounting part 110. The connecting part 120 is used to connect the main body housing of the clothes drying machine.

[0058] like Figure 3 , 4 As shown in Figure 6, the container 400 includes a bottom 410 and a lid 420. A first side of the lid 420 is connected to the bottom 410 via a hinge 430, and a second side of the lid 420 is connected to the bottom 410 via a lock 440. The lock 440 includes a lock housing 441 and a bolt 442. A lock hole 443 is provided on the side wall of the bottom 410. The bolt 442 can enter or exit the lock hole 443. A button 450 is provided on the lock housing 441. When the button 450 is pressed, the bolt 442 exits the lock hole 443; when the button 450 is released, the bolt 442 enters the lock hole 443.

[0059] like Figure 10 , 11As shown, the head of the coil spring 312 has a feature slot m that can cooperate with the fixing post of the coil spring 312 in the lower cavity of the housing 311. It is only necessary to insert the feature slot into the fixing post. The tail of the coil spring 312 has a feature hole n. The function of this hole is to connect the traction rope 320 to it, so that it can achieve the contraction and release of the rope under the force of the coil spring 312.
