[0001] The present application relates to the technical field of airing equipment, in particular to an airing device. BACKGROUND

[0002] The clothes airing machine is widely used in daily life, and two airing rods are usually arranged in the vertical direction, the upper airing rod can air clothes, and the lower airing rod can air clothes or a quilt. Since the two airing rods occupy a large space in the vertical direction, a winding reel is usually arranged to wind a steel wire rope, so as to realize the lifting of the lower airing rod. The winding reel, the steel wire rope and the pulley are complex in structure and inconvenient to operate, and have a high failure rate. SUMMARY

[0003] The present application aims to provide an airing device to solve the technical problems of complex structure, inconvenience in operation and high failure rate in the prior art.

[0004] According to the above idea, the technical scheme adopted by the present application is as follows:

[0005] An airing device comprises:

[0006] An airing rack comprises a first airing rod and a second airing rod, the second airing rod is operable to move close to or away from the first airing rod to form a first airing area between the first airing rod and the second airing rod and a second airing area below the second airing rod;

[0007] A winding structure comprises an elastic component and a connecting belt, one end of the connecting belt is connected to the elastic component, one of the first airing rod and the second airing rod is used to support the elastic component, and the other is connected to the other end of the connecting belt;

[0008] When the second airing rod moves away from the first airing rod under the action of a first external force, the force applied by the connecting belt to the elastic component is equal to the sum of the gravity of the second airing rod and the first external force, and the sum is greater than a predetermined tension value, so that the elastic component is elastically deformed and releases the connecting belt;

[0009] When the first external force disappears, the elastic force of the elastic component is less than or equal to the gravity of the second airing rod, so that the second airing rod can hover at any position away from the first airing rod.

[0010] In some embodiments, the elastic component is a disc spring, the disc spring has an expanded state and a wound state, and the disc spring is in the expanded state when the second airing rod moves away from the first airing rod under the action of an external force.

[0011] In some embodiments, the elastic component is a constant force spring; or the elastic component is a clockwork spring.

[0012] In some embodiments, when the second drying rod is hovering at any position away from the first drying rod and is subjected to a second external force upward, the force applied by the connecting belt to the elastic component is equal to the difference between the gravity of the second drying rod and the second external force, and the difference between the two is less than the rebound force, the elastic component rebounds and recovers the connecting belt under the action of the rebound force, so as to pull the second drying rod to move towards the position close to the first drying rod.

[0013] In some embodiments, the second external force is a transient external force, or the second external force is applied to the second drying rod and maintained for a first set duration.

[0014] In some embodiments, when the second drying rod moves towards the position close to the first drying rod, if the second drying rod is subjected to a third external force downward, the sum of the gravity of the second drying rod and the third external force is greater than the predetermined pulling force value, then the second drying rod changes the moving direction to move away from the first drying rod; otherwise, the second drying rod continues to move towards the position close to the first drying rod until the second drying rod stops moving when abutting against the first drying rod.

[0015] In some embodiments, the second drying rod has a storage position abutting against the first drying rod, in which the second drying rod is inserted into the first drying rod, and / or the second drying rod is magnetically connected to the first drying rod.

[0016] In some embodiments, the second drying rod has a storage position abutting against the first drying rod, in which the connecting belt is in a taut state under the action of the elastic component.

[0017] In some embodiments, the elastic component is arranged inside the second drying rod, and one end of the connecting belt away from the elastic component penetrates out of the second drying rod and is detachably connected to the first drying rod.

[0018] In some embodiments, an end of the second drying rod is provided with a limiting piece for limiting the elastic component from coming out of the second drying rod.

[0019] In some embodiments, an end of the second drying rod is provided with a guiding piece for guiding the connecting belt to penetrate out of the second drying rod.

[0020] Advantages of the present application:

[0021] The drying device proposed in this invention includes a first drying rod and a second drying rod. The winding structure includes an elastic component and a connecting belt. When it is necessary for the second drying rod to move away from the first drying rod, simply pull down the second drying rod, i.e., apply a first external force to the second drying rod. Under the action of the first external force, the force applied by the connecting belt to the elastic component is equal to the sum of the weight of the second drying rod and the first external force, and the sum of the two is greater than a predetermined tension value. The predetermined tension value can stretch the elastic component to undergo elastic deformation and release the connecting belt, thereby allowing the second drying rod to move away from the first drying rod. Simply pulling down the second drying rod, with the help of the elastic component and the connecting belt, can achieve the separation of the second drying rod and the first drying rod. The structure is simple, the operation is convenient, and the elastic component and the connecting belt have strong structural stability and a low failure rate.

[0022] When the first external force disappears, the rebound force of the elastic component is less than or equal to the weight of the second drying rod, ensuring that the elastic component does not rebound against the weight of the second drying rod. This allows the second drying rod to be suspended at any position far from the first drying rod. In other words, the balance between the weight of the second drying rod and the rebound force of the elastic component allows the second drying rod to be suspended at any position far from the first drying rod. The distance between the second and first drying rods can be easily adjusted as needed. Attached Figure Description

[0039] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0040] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0041] See Figures 1 to 7 This embodiment provides a clothes drying device, including a clothes rack 100 and a retractable structure 200. The clothes rack 100 includes a first drying rod 110 and a second drying rod 120. The second drying rod 120 is operable to be close to or away from the first drying rod 110 to form a first hanging area between the first drying rod 110 and the second drying rod 120 and a second hanging area under the second drying rod 120. The retractable structure 200 includes an elastic member 210 and a connecting strap 220. One end of the connecting strap 220 is connected to the elastic member 210. One of the first drying rod 110 and the second drying rod 120 is used to support the elastic member 210, and the other is connected to the other end of the connecting strap 220.

[0042] When the second drying rod 120 moves away from the first drying rod 110 under the action of a downward first external force, the force applied by the connecting strap 220 to the elastic member 210 is equal to the sum of the weight of the second drying rod 120 and the first external force, and the sum of the two is greater than a predetermined tension value, so that the elastic member 210 undergoes elastic deformation and releases the connecting strap 220; when the first external force disappears, the rebound force of the elastic member 210 is less than or equal to the weight of the second drying rod 120, so that the second drying rod 120 can be suspended at any position away from the first drying rod 110.

[0043] When it is necessary for the second drying rod 120 to move away from the first drying rod 110, simply pull down the second drying rod 120, that is, apply a first external force to the second drying rod 120. Under the action of the first external force, the force applied by the connecting strap 220 to the elastic component 210 is equal to the sum of the weight of the second drying rod 120 and the first external force, and the sum of the two is greater than a predetermined tension value. The predetermined tension value can stretch the elastic component 210 to undergo elastic deformation and release the connecting strap 220, thereby making the second drying rod 120 move away from the first drying rod 110. Simply pull down the second drying rod 120, and with the cooperation of the elastic component 210 and the connecting strap 220, the second drying rod 120 and the first drying rod 110 can be moved away from each other. The structure is simple, the operation is convenient, the elastic component 210 and the connecting strap 220 have strong structural stability and a low failure rate.

[0044] When the first external force disappears, the rebound force of the elastic component 210 is less than or equal to the weight of the second drying rod 120, so that the elastic component 210 will not rebound against the weight of the second drying rod 120. Therefore, the second drying rod 120 can be suspended at any position away from the first drying rod 110. In other words, by balancing the weight of the second drying rod 120 with the rebound force of the elastic component 210, the second drying rod 120 can be suspended at any position away from the first drying rod 110. The distance between the second drying rod 120 and the first drying rod 110 can be adjusted as needed, making adjustment convenient.

[0045] The predetermined tensile force value is the critical tensile force that causes the elastic component 210 to undergo elastic deformation. When the tensile force on the elastic component 210 exceeds the critical tensile force, the elastic component 210 undergoes elastic deformation. After elastic deformation, the elastic component 210 tends to recover its deformation under its own elasticity. Therefore, the elastic component 210 applies a rebound force to the connecting strip 220 it is connected to. If the force exerted by the connecting strip 220 on the elastic component 210 is greater than the rebound force, the elastic component 210 will not rebound. If the force exerted by the connecting strip 220 on the elastic component 210 is less than the rebound force, the elastic component 210 rebounds under its own elasticity, returning to its undeformed state. Therefore, the predetermined tensile force value and the rebound force are set according to the properties of the elastic component 210 itself. Different elastic components 210 may have different predetermined tensile force values ​​and rebound forces.

[0046] The connecting strip 220 is elongated and serves a connecting function. During the adjustment of the distance between the second drying rod 120 and the first drying rod 110, the connecting strip 220 itself does not undergo elastic deformation. To adapt to installation space, the connecting strip 220 can be bent and extended without affecting its performance. The connecting strip 220 can be a thin sheet, or have a circular, elliptical, or other cross-sectional shape; its shape is not limited here. The connecting strip 220 can be made of nylon or steel wire; its material is not limited here.

[0047] In some embodiments, the drying device further includes a damping structure that selectively contacts the connecting strap 220. When the damping structure contacts the connecting strap 220, it clamps or presses the connecting strap 220 to limit its movement, keeping the second drying rod 120 in its current position. The distance between the second drying rod 120 and the first drying rod 110 remains constant, allowing heavy objects to be hung or clothing to be removed from the second drying rod 120. When the damping structure disengages from the connecting strap 220, under external force, the elastic component 210 can release or retract the connecting strap 220, making the distance between the first drying rod 120 and the second drying rod 110 adjustable.

[0048] Optionally, the damping structure includes a damping part and a driving part. The driving part is used to drive the damping part to move between a contact position and a release position. In the contact position, the damping part clamps or presses against the connecting band 220, and in the release position, the damping part moves away from and releases the connecting band 220. The damping part can be a damping block or a damping wheel, and can be made of rubber material. The driving part can be a cylinder or a hydraulic cylinder.

[0049] To facilitate operation of the drive unit, an operating component can be provided on the second drying rod 120. This operating component is electrically connected to the drive unit, allowing the operator to control the start and stop of the drive unit. The operating component can be a button, knob, or lever. Taking a button as an example, after pulling the second drying rod 120 to the appropriate position, pressing the button once moves the drive unit's damping part to the contact position, clamping or pressing the connecting band 220, thus limiting the movement of the second drying rod 120. Pressing the button again moves the drive unit's damping part to the release position, moving the damping part away from and releasing the connecting band 220, at which point the second drying rod 120 can move under external force.

[0050] In some embodiments, the drying device is an electric clothes dryer, and the drying device further includes a main unit, with a first drying rod 110 suspended from the main unit. For example, see [link to example]. Figure 1 , Figure 2 , Figure 4 and Figure 8 The first drying rod 110 is connected to the main unit via a connecting rope 310, which can be released and retracted to adjust the distance between the first drying rod 110 and the main unit. The main unit can be an existing main unit. In some embodiments, the drying device is a manual clothes drying machine, and the first drying rod 110 can be fixed to the roof via the connecting rope 310, or supported by a support rod.

[0051] In this embodiment, the connecting rope 310 is fixedly connected to the first drying rod 110. Specifically, the drying device also includes a fixing head 320 and a fixing seat 330. The end of the connecting rope 310 has a locking head that can be locked into the fixing head 320. The fixing head 320 is installed in the fixing seat 330, and the fixing seat 330 can be inserted into the fixing hole of the first drying rod 110. This facilitates the assembly of the connecting rope 310 and the first drying rod 110, thereby simplifying the fixing method of the drying device.

[0052] The connecting rope 310 is long and serves a connecting function; it does not undergo elastic deformation. To adapt to installation space, the connecting rope 310 can be bent and extended without affecting its performance. The cross-sectional shape of the connecting rope 310 can be circular, elliptical, square, or other shapes; no restrictions are placed on its shape. The connecting rope 310 can be made of nylon or steel wire; no restrictions are placed on its material.

[0053] In this embodiment, the elastic component 210 is a disc spring, which has an unfolded state and a coiled state. When the second drying rod 120 moves away from the first drying rod 110 under the action of an external force, the disc spring is in the unfolded state. Alternatively, the elastic component 210 can be a constant-force coil spring, in which case when the second drying rod 120 moves away from the first drying rod 110 under the action of an external force, the constant-force coil spring unfolds relative to the coil spring axis and releases the connecting strap 220. Alternatively, see [link to relevant documentation]. Figure 9 The elastic component 210 is a spring. When the second drying rod 120 moves away from the first drying rod 110 under the action of external force, the spring tightens around the coil spring shaft and releases the connecting belt 220.

[0054] Both the constant-force coil spring and the clockwork spring are existing structures. The constant-force coil spring is made of high-strength stainless steel. The high-strength steel strip is shaped using spring production equipment, and when stretched by an external force, the constant-force coil spring naturally coils back, generating a rebound force. Regardless of the load size or the degree of extension of the constant-force coil spring, it applies essentially the same force to the load. In the drying device, the constant-force coil spring is responsible for bearing the weight of the second drying rod 120 and enabling it to move smoothly up and down, and to be suspended at any position. By adjusting the tension of the constant-force coil spring, different sizes, weights, and movement stability of the second drying rod 120 can be accommodated. The clockwork spring is typically made of spring steel with good elasticity and toughness, a material that ensures the spring maintains its elasticity and durability during long-term use.

[0055] The constant force coil spring can provide a constant tension to the load, that is, the rebound force is constant. As long as the rebound force is set to be less than or equal to the weight of the second drying rod 120, the weight of the second drying rod 120 can be used to balance the rebound force of the elastic component 210, so that the second drying rod 120 can be suspended at any position away from the first drying rod 110.

[0056] When the second drying rod 120 is suspended at any position away from the first drying rod 110 and subjected to an upward second external force, the force exerted by the connecting strap 220 on the elastic member 210 is equal to the difference between the weight of the second drying rod 120 and the second external force, and the difference is less than the rebound force. This causes the elastic member 210 to rebound under the action of the rebound force and retract the connecting strap 220, thereby pulling the second drying rod 120 closer to the first drying rod 110. The upward second external force acts on the second drying rod 120, making the force exerted by the connecting strap 220 on the elastic member 210 less than the rebound force of the elastic member 210. Consequently, the elastic deformation of the elastic member 210 recovers, retracting the connecting strap 220 and allowing the second drying rod 120 to move closer to the first drying rod 110.

[0057] In some embodiments, the second external force is an instantaneous external force; simply lifting the second drying rod 120 slightly will automatically bring it closer to the first drying rod 110, making it easy to store. In some embodiments, the second external force is applied to the second drying rod 120 and maintained for a first set duration; when storing the second drying rod 120, it is necessary to continuously lift the second drying rod 120 upwards until it is completely stored.

[0058] When the second drying rod 120 moves toward a position closer to the first drying rod 110, if the second drying rod 120 is subjected to a downward third external force, and the sum of the weight of the second drying rod 120 and the third external force is greater than a predetermined pulling force value, then the second drying rod 120 changes its direction of movement and moves away from the first drying rod 110; otherwise, the second drying rod 120 continues to move toward a position closer to the first drying rod 110 until the second drying rod 120 stops moving when it touches the first drying rod 110.

[0059] During the process of retrieving the second drying rod 120, the second drying rod 120 moves closer to the first drying rod 110. If the second drying rod 120 is subjected to a downward third external force, the direction of movement of the second drying rod 120 will change, causing the second drying rod 120 to move away from the first drying rod 110, which is suitable for reducing the distance between the second drying rod 120 and the first drying rod 110. In other words, when the second drying rod 120 is suspended in the first position, if it is necessary to increase the distance between the second drying rod 120 and the first drying rod 110, the second drying rod 120 is pulled down; if it is necessary to decrease the distance between the second drying rod 120 and the first drying rod 110, the second drying rod 120 is lifted up and a third downward external force is applied to the second drying rod 120 at an appropriate position. If the sum of the weight of the second drying rod 120 and the third external force is greater than the predetermined pulling force value, the second drying rod 120 changes its direction of movement and moves away from the first drying rod 110. Thus, during the process of retrieving the second drying rod 120, by changing the force applied, the second drying rod 120 can be suspended again in a second position higher than the first position.

[0060] By incorporating the elastic component 210, the distance between the second drying rod 120 and the first drying rod 110 can be easily adjusted, which not only improves the space utilization of the drying device but also makes its use more convenient. The retractable structure 200 enables gravity locking and easy release, simplifying the unfolding and storage of the drying device without complex operating procedures. This reduces the difficulty of using the drying device, simplifies its structure, and improves its reliability.

[0061] The second drying rod 120 has a storage position that abuts against the first drying rod 110. In the storage position, the second drying rod 120 abuts against the first drying rod 110, and the second drying rod 120 is inserted into the first drying rod 110, and / or the second drying rod 120 is magnetically connected to the first drying rod 110. This insertion and / or magnetic connection between the first drying rod 110 and the second drying rod 120, compared to a simple abutment, makes the connection between the first drying rod 110 and the second drying rod 120 more stable, preventing the second drying rod 120 from easily detaching from the first drying rod 110 under wind or other external forces.

[0062] The magnetic connection can be configured in several ways. For example, the first drying rod 110 may have a magnet, and the second drying rod 120 may have a metal component that can be attracted by the magnet; the second drying rod 120 may have a magnet, and the first drying rod 110 may have a metal component that can be attracted by the magnet; or both the first and second drying rods 110 may have magnets. Furthermore, the magnets and metal components can be configured in various ways. For instance, magnets may be embedded in the first drying rod 110 and / or the second drying rod 120; a magnetic coating may be applied to the surface of the first drying rod 110 and / or the second drying rod 120; the first drying rod 110 or the second drying rod 120 may be directly made of magnetic material; a metal component may be embedded in the first drying rod 110 or the second drying rod 120; or the first drying rod 110 or the second drying rod 120 may be directly made of metal.

[0063] In this embodiment, when the second drying rod 120 abuts against the first drying rod 110, the second drying rod 120 and the first drying rod 110 are inserted into each other, and the second drying rod 120 and the first drying rod 110 are magnetically connected. Specifically, the first drying rod 110 is provided with a magnet 400, and the second drying rod 120 is provided with a metal part that can be attracted by the magnet 400, or the second drying rod 120 is directly made of metal. The magnetic attachment design not only enhances the overall stability of the drying device, but also makes the appearance of the stored drying device neater and more aesthetically pleasing.

[0064] One of the second drying rod 120 and the first drying rod 110 has a protrusion 121, and the other has a groove 111. In the storage position, the protrusion 121 and the groove 111 are inserted into each other. In this embodiment, the second drying rod 120 has a protrusion 121 extending along its length, and the first drying rod 110 has a groove 111 extending along its length. The protrusion 121 can be inserted into the groove 111. It is understood that during actual storage, under the rebound action of the elastic member 210, the distance between the first drying rod 110 and the second drying rod 120 decreases. When the protrusion 121 is inserted into the groove 111, the first drying rod 110 and the second drying rod 120 have the same height in the vertical direction, further reducing the volume occupied by the entire drying device when stored, thereby further improving user satisfaction.

[0065] Furthermore, the first drying rod 110 is provided with a groove 111, and the magnet 400 is disposed within the groove 111, allowing the second drying rod 120 to be magnetically attracted to the magnet 400. By placing the magnet 400 within the groove 111, space is fully utilized, resulting in a more stable fit between the second drying rod 120 and the first drying rod 110. The magnetic attraction between the second drying rod 120 and the first drying rod 110 during insertion achieves automatic adhesion, and this labor-saving and recyclable mechanism improves the ease of use of the drying device.

[0066] The second drying rod 120 has a storage position that abuts against the first drying rod 110. In the storage position, the second drying rod 120 abuts against the first drying rod 110, and the connecting strap 220 is taut under the action of the elastic component 210. This not only ensures a stable fit between the second drying rod 120 and the first drying rod 110, but also maintains a certain pulling force when the second drying rod 120 is pulled down, improving the user experience.

[0067] In this embodiment, the elastic component 210 is disposed inside the second drying rod 120, and the end of the connecting strap 220 away from the elastic component 210 extends out of the second drying rod 120 and is detachably connected to the first drying rod 110. By disposing of the elastic component 210 inside the second drying rod 120, space is fully utilized, ensuring a neat appearance. The detachable connection of the connecting strap 220 to the first drying rod 110 facilitates installation, disassembly, and replacement. In other embodiments, the elastic component 210 is disposed inside the first drying rod 110, and the end of the connecting strap 220 away from the elastic component 210 extends out of the first drying rod 110 and is detachably connected to the second drying rod 120.

[0068] When the second drying rod 120 is pulled down, a first external force is applied to the second drying rod 120. Under the action of the first external force, the second drying rod 120 moves away from the first drying rod 110, the elastic component 210 gradually unfolds, and the connecting strap 220 is released and moved out of the second drying rod 120. When retracting, the elastic component 210 rebounds under the action of the rebound force and retracts the connecting strap 220, so that the connecting strap 220 is retracted into the second drying rod 120 to save space.

[0069] See Figure 4 and Figure 5 The winding structure 200 also includes a mounting box 230, in which the elastic member 210 is housed. One end of the elastic member 210 can be pulled out of the mounting box 230 by the connecting strap 220. The mounting box 230 is detachably connected to the second drying rod 120. Installing the elastic member 210 in the mounting box 230 not only protects the elastic member 210 but also prevents the elastic member 210 from twisting when pulled by the connecting strap 220, thereby ensuring stable adjustment of the distance between the first drying rod 110 and the second drying rod 120. The detachable connection between the mounting box 230 and the second drying rod 120 facilitates installation, removal, and replacement.

[0070] The mounting box 230 and the second drying rod 120 can be connected by snap-fit, bolt, adhesive, or magnetic attraction. Optionally, the outer wall of the mounting box 230 is provided with a snap-fit ​​structure, which snaps the mounting box 230 onto the second drying rod 120 to prevent the mounting box 230 from shaking within the second drying rod 120. Of course, the mounting box 230 can also be provided with positioning holes, which, by engaging with positioning posts provided on the second drying rod 120, can also fix the mounting box 230 onto the second drying rod 120.

[0071] Specifically, see Figure 6 The second drying rod 120 is a split structure, comprising a drying rod 122 and a drying cover 123. The drying rod 122 has a mounting groove 1221 for accommodating the mounting box 230 and part of the connecting strap 220. The drying cover 123 is fastened to the drying rod 122 to close the mounting groove 1221. Understandably, during actual assembly, the drying cover 123 can be opened, and then the mounting box 230 and connecting strap 220 can be installed into the mounting groove 1221 through the opening, with the connecting strap 220 straightened. Finally, the drying cover 123 can be fastened to the drying rod 122. This installation method is very simple and avoids the connecting strap 220 from becoming tangled inside the second drying rod 120.

[0072] Furthermore, the mounting groove 1221 extends through to the end of the second drying rod 120, and the second drying rod 120 also includes a second end 124, which is inserted into the end of the second drying rod 120 to seal the mounting groove 1221. The mounting groove 1221 extends through to the end of the second drying rod 120 to facilitate the installation of components such as the connecting strap 220, and the second end 124 is inserted into the end of the second drying rod 120 to serve as a seal and limit.

[0073] Optionally, the mounting box 230 has a splicing structure, comprising a first box body 231 and a second box body 232, with the first box body 231 fastened to the second box body 232. This allows the elastic component 210 to be easily inserted into the mounting box 230 and facilitates the replacement of the elastic component 210.

[0074] The mounting box 230 contains a coil spring shaft for mounting the elastic member 210. One end of the elastic member 210 is connected to the coil spring shaft, and the other end is connected to the connecting belt 220. The elastic member 210 can be unfolded or coiled relative to the coil spring shaft.

[0075] The connecting strap 220 and the elastic component 210 can be directly connected or indirectly connected. In this embodiment, the connecting strap 220 and the elastic component 210 are connected by a buckle 240. Using the buckle 240 to connect the connecting strap 220 and the elastic component 210 is convenient, easy to assemble, and helps to improve the connection stability between the connecting strap 220 and the elastic component 210.

[0076] Optionally, see Figure 5 The buckle 240 is a spliced ​​structure, comprising a first buckle plate 241 and a second buckle plate 242. The first buckle plate 241 has a locking hole 2411, and the first end of the connecting strap 220 has a first locking head 221, which can be locked into the locking hole 2411. This ensures a stable connection between the first end of the connecting strap 220 and the buckle 240. Optionally, the end of the elastic member 210 has two limiting grooves 211, the first buckle plate 241 has two limiting protrusions, and the second buckle plate 242 has limiting slots 2421 that mate with the limiting protrusions. In actual assembly, when the end of the elastic member 210 is attached to the second buckle plate 242 and the first buckle plate 241 is fastened to the second buckle plate 242, the limiting protrusions on the first buckle plate 241 pass through the limiting grooves 211 and insert into the limiting slots 2421. This securely fixes the end of the elastic member 210 to the buckle 240.

[0077] See Figure 6The second drying rod 120 has a limiting member 130 at its end, which restricts the elastic component 210 from detaching from the second drying rod 120; and / or, the second drying rod 120 has a guide member 140 at its end, which guides the connecting strap 220 through the second drying rod 120. By providing the limiting member 130, the elastic component 210 is restricted from detaching from the second drying rod 120, thus preventing any impact on its smooth retraction. By providing the guide member 140, the connecting strap 220 is guided, ensuring that the connecting strap 220 located outside the second drying rod 120 remains vertical, guaranteeing the stability of the second drying rod 120's movement.

[0078] Specifically, the limiting member 130 has a through hole allowing the connecting strap 220 to pass through, and the wire buckle 240 can abut against the limiting member 130. When the second drying rod 120 moves away from the first drying rod 110, when the wire buckle 240 abuts against the limiting member 130, the limiting member 130 limits the wire buckle 240, and at this time the second drying rod 120 moves to its farthest point. The limiting member 130 is engaged with the second drying rod 120 by snapping, bolting, or gluing.

[0079] The guide component 140 is a reel, which is rotatable relative to the second drying rod 120. The second drying rod 120 has a second thread-holding groove 125 corresponding to the reel. The second end of the connecting strap 220 passes around the reel, exits through the second thread-holding groove 125 from the second drying rod 120, and connects to the first drying rod 110. Therefore, during actual adjustment, the connecting strap 220 is kept stable by the combined constraints of the reel and the second thread-holding groove 125, preventing it from becoming tangled or knotted and jammed. During installation, the second end of the connecting strap 220 extends out of the second drying rod 120, and the second end 124 is inserted into the end of the second drying rod 120.

[0080] See Figure 7 The connecting strap 220 can be snapped into the first drying rod 110. Specifically, the first drying rod 110 is provided with a first wire-locking groove 112, and the second end of the connecting strap 220 passes through the second wire-locking groove 125 and is connected to the first wire-locking groove 112 on the first drying rod 110.

[0081] Furthermore, the first drying rod 110 is hollow, with both ends open. The first wire-locking groove 112 is also open at one end facing the end of the first drying rod 110, i.e., the first wire-locking groove 112 is a U-shaped groove, facilitating the insertion of the connecting strap 220. The first drying rod 110 also includes a first end 113, which is inserted into the end of the first drying rod 110. In actual installation, it is only necessary to insert the second clamp 222 of the connecting strap 220 into the first wire-locking groove 112, and then insert the first end 113 into the end of the first drying rod 110, facilitating the connection between the connecting strap 220 and the first drying rod 110. The hollow design of the first drying rod 110 reduces its weight, thereby helping to reduce the weight of the entire drying device.

[0082] In this embodiment, two sets of winding structures 200 are provided. Two elastic components 210 are located at the middle position of the second drying rod 120, and two connecting straps 220 are distributed at both ends of the first drying rod 110 along its length. By providing two sets of winding structures 200, the second drying rod 120 is subjected to balanced forces.

[0083] When the second drying rod 120 is in contact with the first drying rod 110, the protrusion 121 of the second drying rod 120 is inserted into the groove 111 of the first drying rod 110, and the second drying rod 120 and the first drying rod 110 are magnetically attracted, and the connecting strap 220 is in a taut state. When it is necessary for the second drying rod 120 to move away from the first drying rod 110, simply pull down the second drying rod 120, that is, apply a first external force to the second drying rod 120. Under the action of the first external force, the force applied by the connecting strap 220 to the elastic member 210 is equal to the sum of the weight of the second drying rod 120 and the first external force, and the sum of the two is greater than a predetermined tension value, so that the elastic member 210 undergoes elastic deformation and releases the connecting strap 220, and the second drying rod 120 moves away from the first drying rod 110.

[0084] When the second drying rod 120 is moved to the desired position, the second drying rod 120 is released, that is, the first external force disappears, and the rebound force of the elastic component 210 is less than or equal to the weight of the second drying rod 120 so that the second drying rod 120 can be suspended at a position away from the first drying rod 110.

[0085] When it is necessary to increase the distance between the second drying rod 120 and the first drying rod 110, pull the second drying rod 120 downwards so that the second drying rod 120 and the first drying rod 110 continue to move away from each other. When the first external force applied downwards can no longer pull the second drying rod 120, it indicates that the wire buckle 240 abuts against the limiting member 130, and the second drying rod 120 has reached its lowest position.

[0086] When it is necessary to reduce the distance between the second drying rod 120 and the first drying rod 110, the second drying rod 120 is gently lifted upwards. The second drying rod 120 is subjected to an upward second external force. The force applied by the connecting strap 220 to the elastic member 210 is equal to the difference between the weight of the second drying rod 120 and the second external force, and the difference is less than the rebound force. This causes the elastic member 210 to rebound under the action of the rebound force and retract the connecting strap 220, thereby pulling the second drying rod 120 to move closer to the first drying rod 110. At an appropriate position, a downward third external force is applied to the second drying rod 120. The sum of the weight of the second drying rod 120 and the third external force is greater than a predetermined pulling force value. Then, the second drying rod 120 changes its direction of movement and moves away from the first drying rod 110. Releasing the second drying rod 120 allows it to suspend. This achieves the goal of suspending the second drying rod 120 at the desired position again by changing the force applied during the retraction process.

[0087] When the second drying rod 120 needs to be retracted, it is gently lifted upwards. The second drying rod 120 is subjected to an upward second external force. The force applied by the connecting strap 220 to the elastic member 210 is equal to the difference between the weight of the second drying rod 120 and the second external force, and the difference is less than the rebound force. This causes the elastic member 210 to rebound under the action of the rebound force and retract the connecting strap 220, so as to pull the second drying rod 120 to move closer to the first drying rod 110 until the protrusion 121 of the second drying rod 120 is inserted into the groove 111 of the first drying rod 110. The second drying rod 120 and the first drying rod 110 are magnetically attracted, and the second drying rod 120 stops moving.
