[0018] 5. In this embodiment of the utility model, the driving component further includes a movable bracket, which includes a connecting end and a sensing end. The connecting end is fixedly connected to the first housing, and the sensing end faces the fixed guide rail. A first Hall sensor and a second Hall sensor are disposed on the sensing end. A control module is disposed inside the first housing, and the first and second Hall sensors are electrically connected to the control module and the driving component. A first magnetic suction element and a second magnetic suction element are disposed at intervals on the outer surface of the side of the fixed guide rail facing the sensing end. The first and second Hall sensors correspond to the first and second magnetic suction elements, respectively. The electrical signal of the Hall sensor is transmitted to the driving component through the control module. The driving component controls the movement of the movable guide rail on the fixed guide rail according to the received electrical signal, thereby realizing the position adjustment of the first housing and the second housing. This allows for precise control of the movement position of the first housing and the second housing, making the towel rack more stable and reliable during use and storage. At the same time, the combined use of the Hall sensor and the magnetic suction element can also improve the intelligence of the towel rack to a certain extent, allowing users to preset the movement position of the towel rack through the control module and realize one-click control of the unfolding and storage of the towel rack, improving the convenience and user experience of the towel rack.

[0019] 6. In this embodiment of the invention, the second housing is further provided with a control port, which is electrically connected to a control module.

By releasing the position sensing control of the Hall sensors on the first and second housings through the control port, the user can control the continuous rotation of the lead screw to automatically detach the first and second housings from the storage box, making the disassembly and replacement of the towel rack components more convenient.

[0020] 7. In this embodiment of the utility model, the towel rack also includes a power cord. The power cord is bent and placed inside the storage box. When the first housing is completely stored inside the storage box, there is a gap between the first housing and the bottom surface of the storage box. The power cord is placed in the gap. When the first housing moves relative to the storage box, the bent power cord is stretched and compressed according to a specific route and angle, which avoids the power cord being excessively stretched or twisted during the movement, and ensures the connection stability and service life of the power cord.

[0021] 8. In this embodiment of the utility model, the first shell and the second shell can be completely stored in the storage box. When the towel rack is in the storage state, the towel rack presents a compact box-shaped structure. The towel rack is embedded in the wall and connected to the main power line in the wall. The second shell on the outside of the towel rack can be almost flush with the wall, so that the installed towel rack is not only beautiful and elegant, but also effectively reduces the space occupied. The towel rack is small and beautiful when not in use.

[0022] 9. In this embodiment of the utility model, the control module further includes a display panel, which is located on the side of the second housing away from the first housing. The display panel is electrically connected to the heating module. Through the display panel, the user can intuitively understand the heating status, disinfection progress and other relevant information of the towel rack, making the operation of the towel rack more intuitive and convenient.

[0023] 10. In this embodiment of the utility model, multiple gesture sensors are spaced apart on the display panel, allowing users to control the towel rack via gestures.

[0048] Please refer to the following: Figures 1-5 The first embodiment of this utility model provides a retractable towel rack 100, which includes a first housing 1, a second housing 2, and a connecting post 3. The first housing 1 and the second housing 2 are fixedly connected to the connecting post 3 and are spaced apart. The retractable towel rack 100 also includes a control module 11, which includes a photosensitive element 113, a light-emitting element 112, and a circuit board 111. The photosensitive element 113 is disposed inside the second housing 2, and a heating module 21 is disposed inside the second housing 2. The heating module 21 includes a heating plate 21. 1. The heating plate 211 and the photosensitive element 113 are arranged in parallel; the photosensitive element 113 is at least partially exposed towards the first housing 1 and relative to the second housing 2. The circuit board 111 is placed inside the first housing 1. A light-emitting element 112 is arranged on the side of the first housing 1 facing the second housing 2. The position of the light-emitting element 112 corresponds to the exposed area of ​​the photosensitive element 113. The circuit board 111 is electrically connected to the light-emitting element 112, the photosensitive element 113 and the heating module 21. The circuit board 11 controls the heating plate 211 to heat by the signal detected by the photosensitive element 113.

[0049] In this embodiment, the second housing 2 of the retractable towel rack 100 is used to hang towels. By setting a heating module 21 inside the second housing 2, the heating plate 211 in the heating module 21 can heat and dry the towels, improving the drying speed of the towels and effectively preventing the towels from being damp for a long time and thus breeding bacteria. At the same time, the retractable towel rack 100 is also equipped with a control module 11. The control module 11 includes a light-emitting element 112 and a light-sensing element 113 respectively set on the first housing 1 and the second housing 2. The light-emitting element 112 and the light-sensing element 113 work together to sense whether there is a towel hanging on the second housing 2. Then, the control module 11, which is electrically connected to the heating module 21, controls whether the heating plate 211 heats, making the heating of the towels by the retractable towel rack 100 more intelligent and efficient. When the light-sensing element 113 senses the presence of a towel, the light-emitting element 112 emits light. After the light is blocked by the towel, the light intensity received by the light-sensing element 113 is reduced, thereby triggering the circuit board 111 of the control module 11 to control the start of the heating module 21 to heat and dry the towels. When the towel is removed, the light intensity sensed by the light sensor 113 returns to normal, and the control module 11 controls the heating module 21 to stop heating. Alternatively, the control module 11 can preset the heating time, and when the towel is detected, it controls the heating module 21 to heat for the preset time. This achieves intelligent sensing control, avoids energy waste, and makes the heating and drying function of the retractable towel rack 100 more accurate and efficient.

[0050] As one implementation method, please refer to [the relevant documentation]. Figure 4 and Figure 5 Multiple receivers 1131 are spaced apart on the photosensitive element 113. Multiple clearance holes 22 are provided on the side of the second housing 2 facing the first housing 1, with the receivers 1131 placed within the clearance holes 22. The light-emitting element 112 emits light towards the receivers 1131. The arrangement of multiple receivers 1131 and light-emitting elements 112 further improves the accuracy of the photosensitive element 113 in sensing towels, avoiding situations where the control module 11 cannot be triggered due to towels being too small or the hanging position lacking a corresponding photosensitive element 113. This makes the retractable towel rack 100 more sensitive and reliable in sensing towels. Simultaneously, the arrangement of multiple receivers 1131 and light-emitting elements 112 also expands the applicability of the retractable towel rack 100 to a certain extent, making it suitable for towels of different sizes and thicknesses, thus improving the versatility of the retractable towel rack 100.

[0051] As one implementation method, please refer to Figure 4The first housing 1 includes an upper end face 12 and a lower end face 13. Multiple light-emitting elements 112 are arranged in a single row at intervals along a direction parallel to the upper end face 12. Light-sensing elements 113 and light-emitting elements 112 are located on the same plane, and receivers 1131 and light-emitting elements 112 are arranged in a one-to-one correspondence. By arranging multiple light-emitting elements 112 in a single row at intervals, the uniformity of light illumination can be further improved, allowing the light-sensing elements 113 to more accurately receive changes in light after being blocked by a towel, thus more accurately sensing the presence of the towel. At the same time, the single-row arrangement can also reduce the space occupied by the light-emitting elements 112 and light-sensing elements 113 to a certain extent, making the structure of the retractable towel rack 100 more compact and easier to install and use.

[0052] For further details, please refer to the following: Figure 4 and Figure 5 The light-emitting element 112 is positioned near the upper end face 12, and the light-sensing element 113 is positioned corresponding to the light-emitting element 112. The heating plate is located on the side of the light-sensing element 113 near the lower end face 13. When the towel is hung on the second housing 2 from the upper end, because the light-emitting element 112 and the light-sensing element 113 are positioned closer to the upper ends of the first housing 1 and the second housing 2, the towel can more accurately and quickly trigger the control module 11 to start the heating module 21 to heat and dry the towel. Conversely, if the light-sensing element 113 is positioned on the side near the lower end face 13, it may be possible that when the towel is not long enough, the towel cannot block the light-sensing element 113, resulting in the inability to start the heating module 21.

[0053] As one implementation method, please refer to [the relevant documentation]. Figure 1 and Figure 4 The extendable towel rack 100 also includes a disinfection module 14, which is located on the side of the first housing 1 facing the second housing 2. The control module 11 is electrically connected to the disinfection module 14. The disinfection module 14 includes an ultraviolet lamp 141, which is alternately arranged with the light-emitting element 112.

[0054] The ultraviolet lamp 141 in the disinfection module 14 can disinfect towels hanging on the second housing 2 with ultraviolet light, further improving the hygiene of the towels. The ultraviolet lamp 141 and the light-emitting element 112 are arranged alternately, which can effectively utilize the space on the first housing 1 while disinfecting the towels more evenly. The disinfection module 14 works in conjunction with the control module 11. The opening and closing of the ultraviolet lamp 141 is controlled by the control module 11 according to the sensing result of the photosensitive element 113, realizing intelligent disinfection function. When the photosensitive element 113 senses the presence of the towel, the control module 11 can start the heating module 21 to heat and dry the towel, and at the same time start the disinfection module 14 to disinfect the towel with ultraviolet light. Alternatively, the control module 11 can preset a specific program to control the heating module 21 and the disinfection module 14 to heat and disinfect the towel in different sequences, realizing integrated operation of heating, drying and disinfection, improving the practicality and convenience of the retractable towel rack 100.

[0055] As one implementation method, please refer to Figure 5 Two heating plates 211 are provided, symmetrically arranged on both sides of the second housing 2, one near and one away from the first housing 1. This symmetrical arrangement of the heating plates 211 allows for more even heating and drying of the towels, preventing uneven drying caused by localized overheating or underheating, and improving the drying effect. Simultaneously, the symmetrical arrangement of the heating plates 211 also enhances the heating efficiency of the retractable towel rack 100, allowing the towels to reach the desired dryness more quickly. Furthermore, the symmetrical arrangement of the heating plates 211 on both sides of the second housing 2, near and away from the first housing 1, ensures good heat dissipation while heating and drying the towels, preventing excessive internal temperature due to prolonged heating and improving the safety and stability of the retractable towel rack 100.

[0056] As one implementation method, please refer to Figure 5 The control module 11 also includes a display panel 23, which is located on the side of the second housing 2 away from the first housing 1. The display panel 23 is electrically connected to the heating module 21 and the circuit board 111. Through the display panel 23, users can intuitively understand the heating status, disinfection progress and other relevant information of the retractable towel rack 100, making the operation of the retractable towel rack 100 more intuitive and convenient.

[0057] In one embodiment, both the first housing 1 and the second housing 2 are set as cuboids, and the connecting post 3 is set as a cylinder. The connecting post 3 is located between the first housing 1 and the second housing 2, and the connecting post 3 is fixedly connected to the end faces of the first housing 1 and the second housing 2. After the fixed connection, the first housing 1 and the second housing 2 are aligned around their perimeters, forming a compact and aesthetically pleasing retractable towel rack 100, which is easy to install and use.

[0058] The retractable towel rack 100 in the first embodiment of this utility model incorporates a heating module 21 and a control module 11 within a first housing 1 and a second housing 2. The control module 11 intelligently senses and controls the towels hanging on the second housing 2, and then controls the heating module 21 to turn on and off based on the sensing results, thus completing the heating and drying of the towels. By incorporating the heating module 21 within the second housing 2, the retractable towel rack 100 achieves a relatively small size while improving its efficiency in heating and drying towels. Furthermore, the coordinated control of the heating module 21 and the control module 11 avoids energy waste, making the heating and drying function of the retractable towel rack 100 more accurate and efficient.

[0059] Please see Figure 6 The second embodiment of this utility model also provides another retractable towel rack 200. The difference between the retractable towel rack 200 in the second embodiment and the retractable towel rack 100 in the first embodiment is as follows:

[0060] The extendable towel rack 200 also includes a storage box 4, in which a drive assembly 41 is disposed. The side of the first housing 1 away from the second housing 2 is at least partially movably placed in the storage box 4. The drive assembly 41 is at least partially placed in the connecting post 3 and connects the first housing 1 and / or the second housing 2. Specifically, one end of the drive assembly 41 passes through the connecting post 3 and is fixedly connected to the end face of the second housing 2 facing the first housing 1. The drive assembly 41 is used to drive the connecting post 3, the first housing 1 and the second housing 2 to move relative to the storage box 4.

[0061] When towels need to be hung, the first housing 1 and the second housing 2 can be removed from the storage box 4 by the drive component 41, making it convenient for the user to hang the towels on the second housing 2. After use, the first housing 1 and the second housing 2 can be stored back into the storage box 4 by the drive component 41, which reduces the space occupied by the retractable towel rack 200 when not in use and further improves the practicality of the retractable towel rack 200. At the same time, one end of the storage box 4 in the retractable towel rack 200 can be pre-embedded in the wall. When the first housing 1 and the second housing 2 are stored in the storage box 4, the retractable towel rack 200 is ready to use. Meanwhile, the first housing 1 and the second housing 2 are fixedly connected by a hollow connecting column 3, and the drive component 41 is partially placed inside the connecting column 3, making the overall structure of the retractable towel rack 200 more compact. Since the first housing 1 and the second housing 2 move synchronously relative to the storage box 4, the wires of the connecting components between the first housing 1 and the second housing 2 are also relatively stationary. The wires will not be stretched during the retractable movement of the retractable towel rack 200, avoiding poor contact or breakage caused by the stretching of the wires, and improving the stability of the retractable towel rack 200.

[0062] Preferably, the first housing 1 and the second housing 2 can be completely stored in the storage box 4. When the retractable towel rack 200 is in the stored state, the retractable towel rack 200 presents a compact box-shaped structure. The retractable towel rack 200 is embedded in the wall and connected to the main power line in the wall. The second housing 2 on the outside of the retractable towel rack 200 can be almost flush with the wall, so that the retractable towel rack 200 after installation is not only beautiful and elegant, but also effectively reduces the space occupied. The retractable towel rack 200 is more compact and beautiful when not in use.

[0063] As one implementation method, please refer to [the relevant documentation]. Figures 6-8The drive assembly 41 includes a base 411, a fixed guide rail 412, a movable guide rail 415, a lead screw 413, a transmission component 414, and a power unit. The base 411 is fixedly connected to the bottom surface of the storage box 4. One end of the fixed guide rail 412 is fixedly connected to the base 411 and / or the storage box 4, and the movable guide rail 415 is movably sleeved on the fixed guide rail 412. One end of the movable guide rail 415 is fixedly connected to the second housing 2. The transmission component 414 is located inside the movable guide rail 415 and is fixedly connected to the second housing 2. The power unit is fixedly connected to the side of the base 411 away from the fixed guide rail 412, and one end of the lead screw 413 is connected to the power unit. The other end of the lead screw 413 passes through the fixed housing and the movable housing and is threadedly connected to the transmission component 414. The drive assembly 41 enables the automatic extension and retraction of the first housing 1 and the second housing 2, eliminating the need for manual movement of the retractable towel rack 200, making operation more convenient and effortless. Meanwhile, the cooperation between the fixed guide rail 412 and the movable guide rail 415 in the drive assembly 41 makes the movement of the retractable towel rack 200 more stable, avoids the shaking generated during the movement of the retractable towel rack 200, and improves the stability and service life of the retractable towel rack 200.

[0064] As one implementation method, please refer to [the relevant documentation]. Figure 7 and Figure 8 The fixed guide rail 412 has a limiting groove 4121 on its outer surface, and the movable guide rail 415 has a limiting protrusion 4151 on its inner surface. The limiting protrusion 4151 engages with the limiting groove 4121. The limiting groove 4121 and the limiting protrusion 4151 are perpendicular to the bottom surface of the storage box 4. The movable guide rail 415 is movably fitted onto the fixed guide rail 412 through the cooperation of the limiting protrusion 4151 and the limiting groove 4121, making the movement of the movable guide rail 415 on the fixed guide rail 412 more stable and reliable. This further avoids the movable guide rail 415 from shaking or shifting during movement, improving the stability and service life of the retractable towel rack 200. At the same time, the setting of the limiting groove 4121 and the limiting protrusion 4151 can also limit the movement range of the movable guide rail 415 to a certain extent, making the movement of the first housing 1 and the second housing 2 within the storage box 4 more orderly, avoiding structural damage or functional failure caused by excessive movement range.

[0065] As one implementation method, please refer to [the relevant documentation]. Figures 7-9The drive assembly 41 also includes a movable bracket 416, which includes a connecting end 4161 and a sensing end 4162. The connecting end 4161 is fixedly connected to the first housing 1, and the sensing end 4162 faces the fixed guide rail 412. A first Hall sensor 4163 and a second Hall sensor 4164 are provided on the sensing end 4162. A control module 11 is provided inside the first housing 1. The first Hall sensor 4163 and the second Hall sensor 4164 are electrically connected to the control module 11 and the drive assembly 41. A first magnetic member 4122 and a second magnetic member 4123 are spaced apart on the outer surface of the fixed guide rail 412 facing the sensing end 4162. The first Hall sensor 4163 and the second Hall sensor 4164 correspond to the first magnetic member 4122 and the second magnetic member 4123, respectively.

[0066] When the first Hall sensor 4163 and the first magnetic member 4122 are facing each other, and the second Hall sensor 4164 and the second magnetic member 4123 are facing each other, the first Hall sensor 4163 senses the magnetic field of the first magnetic member 4122 and generates an electrical signal, and the second Hall sensor 4164 also senses the magnetic field of the second magnetic member 4123 and generates an electrical signal. At this time, the retractable towel rack 200 is in the storage state. When only the first Hall sensor 4163 and the second magnetic suction member 4123 are in opposition, the first Hall sensor 4163 senses the magnetic field of the second magnetic suction member 4123 and generates an electrical signal. At this time, the retractable towel rack 200 is in the unfolded state. The electrical signal from the Hall sensor is transmitted to the drive component 41 through the control module 11. The drive component 41 controls the movement of the movable guide rail 415 on the fixed guide rail 412 according to the received electrical signal, thereby realizing the position adjustment of the first housing 1 and the second housing 2. This allows for precise control of the movement position of the first housing 1 and the second housing 2, making the retractable towel rack 200 more stable and reliable during use and storage. At the same time, the combined use of the Hall sensor and the magnetic suction member can also improve the intelligence level of the retractable towel rack 200 to a certain extent, allowing users to preset the movement position of the retractable towel rack 200 through the control module 11, and realize one-button control of the unfolding and storage of the retractable towel rack 200, improving the convenience and user experience of the retractable towel rack 200.

[0067] Specifically, the movable bracket 416 is configured as an L-shaped structure, with the connecting end 4161 and the sensing end 4162 located on the two connected sections of the L-shaped structure. By configuring the movable bracket 416 as an L-shaped structure, the movable bracket 416 can be more compactly attached to and fixed to the first housing 1, reducing the space required for the movable bracket 416.

[0068] Furthermore, a receiving groove 4123 is provided on the outer surface of the fixed guide rail 412, and a clearance groove 4152 corresponding to the receiving groove 4123 is provided on the movable guide rail 415. The first magnetic attractor 4122 and the second magnetic attractor 4123 are spaced apart on the bottom surface of the receiving groove 4123. The sensing end 4162 passes through the clearance groove 4152 and is placed in the receiving groove 4123, so that the first Hall sensor 4163 and the second Hall sensor 4164 on the sensing end 4162 can sense the first magnetic attractor 4122 and the second magnetic attractor 4123.

[0069] As one implementation method, please refer to [the relevant documentation]. Figure 7 and Figure 8 The transmission component 414 is provided with a threaded hole 4141, and one end of the lead screw 413 is placed in the threaded hole 4141. The lead screw 413 is detachably connected to the transmission component 414. The continuous rotation of the lead screw 413 can disengage the transmission component 414 from the lead screw 413, which makes it convenient for users to disassemble and assemble the retractable towel rack 200 according to actual needs, thus improving the flexibility and convenience of the retractable towel rack 200.

[0070] For details, please refer to Figure 6 The second housing 2 is also provided with a control port 43, which is electrically connected to the control module 11. Through the control port 43, the drive component 41 can be controlled to ignore the signal control of the first Hall sensor 4163 and the second Hall sensor 4164, so that the lead screw 413 rotates continuously. Through the control port 43, the position sensing control of the Hall sensor on the first housing 1 and the second housing 2 can be released, so that the user can control the continuous rotation of the lead screw 413 to realize the automatic detachment of the first housing 1 and the second housing 2 from the storage box 4, thereby making it more convenient to disassemble and replace the components of the retractable towel rack 200.

[0071] As one implementation method, please refer to Figure 10 The extendable towel rack 200 also includes a power cord 16, which is bent and positioned inside the storage box 4. When the first housing 1 is fully retracted into the storage box 4, there is a gap between the first housing 1 and the bottom surface of the storage box 4, and the power cord 16 is placed in the gap. A first wiring hole 42 is provided on the side of the storage box 4, and a second wiring hole 15 is provided on the side of the first housing 1 facing the storage box 4. One end of the power cord 16 passes through the first wiring hole 42 and connects to an external power source, while the other end of the power cord 16 passes through the second wiring hole 15 and electrically connects to the control module 11. When the first housing 1 moves relative to the storage box 4, the bent power cord 16 is stretched and compressed according to a specific route and angle, preventing the power cord 16 from being excessively stretched or twisted during movement, thus ensuring the connection stability and service life of the power cord 16.

[0072] As one implementation method, please refer to Figure 11Multiple gesture sensors 231 are spaced apart on the display panel 23, allowing users to control the retractable towel rack 200 via gestures. For example, users can start or stop heating or disinfection functions by using gestures, without needing to directly touch the display panel 23. This reduces the spread of bacteria during operation and further improves the hygiene of the retractable towel rack 200. At the same time, the gesture sensors 231 also make the operation of the retractable towel rack 200 more intelligent and convenient, enhancing the user experience.

[0073] The retractable towel rack 200 in the second embodiment of this utility model is further provided with a storage box 4. A driving component 41 is provided inside the storage box 4 to connect and drive the connecting column 3, the first housing 1, and the second housing 2 to move relative to the storage box 4, so that the retractable towel rack 200 has a telescopic movement function. When the user does not need to use the retractable towel rack 200, the first housing 1 and the second housing 2 can be controlled to be stored in the storage box 4, reducing the volume occupied by the retractable towel rack 200. When the user needs to use the retractable towel rack 200, the first housing 1 and the second housing 2 can be easily extended from the storage box 4 by simple operation, and towels can be easily hung. The operation is simple and quick. In addition, after the extendable towel rack 200 is stored, the design of the storage box 4 is not only beautiful and elegant, but also effectively protects the extendable towel rack 200 from cleaning and safety when not in use, preventing the adhesion of dust and dirt. The telescopic movement structure of the extendable towel rack 200 can also protect the internal cords from excessive pulling or twisting, extending the service life of the extendable towel rack 200.

[0074] In one implementation, a roller 17 is provided on at least one side of the inner surface of the first housing 1 opposite to the inner surface of the storage box 4, and the roller 17 abuts against the storage box 4. The roller 17 makes the movement of the first housing 1 relative to the storage box 4 smoother, reducing friction and resistance during movement and improving the moving efficiency and stability of the retractable towel rack 200. Simultaneously, the roller 17 can also protect the inner surface of the storage box 4 to some extent, preventing scratches or damage to the storage box 4 caused by the first housing 1 during movement, thus extending the service life of the retractable towel rack 200. Furthermore, when the retractable towel rack 200 is placed horizontally, since the first housing 1 and the second housing 2 are only fixedly connected by a connecting post 3 on one side, the other side of the retractable towel rack 200 without the connecting post 3 is prone to shifting under the weight of the towel when a towel is hung on the second housing 2. The roller 17 can balance the force on the retractable towel rack 200, improving its load-bearing capacity and stability.

[0075] In one implementation, a flexible sealing element 18 is provided on the first housing 1. The flexible sealing element 18 is sleeved on the outer periphery of the first housing 1 and abuts against the storage box 4. When the first housing 1 moves relative to the storage box 4, the flexible sealing element 18 moves synchronously with the first housing 1. The flexible sealing element 18 effectively prevents dust and moisture from entering the storage box 4, keeping the inside of the storage box 4 clean and dry, further improving the hygiene and service life of the retractable towel rack 200. At the same time, the flexible sealing element 18 can also reduce the noise of the first housing 1 during movement to a certain extent, making the use of the retractable towel rack 200 quieter and more comfortable.

[0076] Furthermore, the flexible seal 18 is located on the side of the roller 17 near the second housing 2, thereby preventing water droplets and mist from entering the interior of the first housing 1 through the connection gap between the roller 17 and the first housing 1, avoiding short circuits or component damage caused by water droplets and mist, and further improving the safety and reliability of the retractable towel rack 200.

[0077] In one implementation, the connecting post 3 is positioned close to the side of the first housing 1 and the second housing 2, and the roller 17 is positioned close to the opposite side of the first housing 1. This layout design of the connecting post 3 optimizes the overall structure of the retractable towel rack 200. The position of the connecting post 3 close to the side not only provides more hanging space for towels, but the large gap between the roller 17 and the connecting post 3 and their respective positions on both sides of the first housing 1 further enhances the load-bearing capacity and stability of the retractable towel rack 200. Even when hanging heavy towels, the retractable towel rack 200 can remain stable, effectively avoiding displacement or damage caused by excessive load, and improving the practicality and durability of the retractable towel rack 200.

[0078] In the second embodiment of this utility model, the towel rack 200 is equipped with rollers 17 and flexible seals 18 on the first housing 1. The rollers 17 make the first housing 1 move more smoothly relative to the storage box 4, reducing friction and resistance during movement, improving the moving efficiency and stability of the retractable towel rack 200, and also improving the load-bearing capacity and stability of the retractable towel rack 200. Even when hanging heavy towels, the retractable towel rack 200 can remain stable, effectively avoiding displacement or damage caused by excessive load, thus improving the practicality and durability of the retractable towel rack 200. The flexible seals 18 effectively prevent dust and moisture from entering the storage box 4 and the first housing 1, keeping the storage box 4 and the first housing 1 clean and dry, further improving the hygiene and service life of the retractable towel rack 200.
