Description

Technical Field

[0001] This invention relates to the field of towel rack technology, and more particularly to an electric heated towel rack. Background Technology

[0002] Towels are a common item in people's lives, and they are usually damp after washing. Damp towels are prone to bacterial growth, especially in cold winters or in damp, enclosed bathrooms. Wet towels are difficult to dry and may develop mold, which can harm health. Electric towel racks can heat towels to achieve the purpose of quickly drying them.

[0003] Existing electric towel racks come in two types: one with a fixed hanging rod and the other with a rotatable hanging rod. The fixed hanging rod type has limited space, making it unsuitable for drying multiple towels.

[0004] The rotatable structure of the hanging rods allows each rod to rotate relative to the vertical rod, enabling multiple rods to be staggered for hanging clothes or towels and achieving rapid drying. For example, Chinese patent application number CN201920824108.0 discloses "an electric towel rack, wherein multiple heating plates are fixedly connected to the side walls of the first, second, and third movable shafts via positioning pins. The first movable shaft has one heating plate. By adding a rotation function, it facilitates the replacement of space, overcoming the shortcomings of traditional towel racks that simply hold items, achieving both storage and drying of clothes, changing the dampness of the bathroom, improving the bathroom environment, and possessing strong practicality."

[0005] However, the heating plate in this patent is essentially a hanging rod, according to the appendix Figure 3 It can be seen that the heating wires inside adjacent heating plates are directly connected by wires. This connection method has the following disadvantages:

[0006] 1. Heat shrink tubing is required to insulate the wires connecting the heating element. However, it is currently difficult to fit heat shrink tubing between heating plates, which greatly increases the difficulty of product assembly and results in extremely low assembly efficiency.

[0007] 2. The heating plate must be connected to an external power source. The heating plate rotates while the external power source remains stationary. Rotating the heating plate will cause the external power cord to bend and stretch continuously, which will affect the feel of rotating it.

[0008] 3. Adjacent heating plates are connected by wires. During the rotation of the heating plates, the wires will rub against the inner wall of the heating plates, which will affect the feel of rotation and reduce the service life of the wires. Summary of the Invention

[0009] The purpose of this invention is to provide an electric towel rack that solves the problem in the prior art where adjacent heating wires of electric towel racks are directly connected by wires, which affects the efficiency of product assembly and disassembly and the user experience.

[0052] The following detailed description illustrates the specific implementation method:

[0053] The reference numerals in the accompanying drawings include: vertical rod 1, fixed shaft 2, conductive wire 3, conductive ring 4, hanging rod 5, heating element 6, conductive sleeve 7, short shaft 8, groove 9, center rod 10, positioning post 11, strip-shaped limiting groove 12, connecting sleeve 13, through hole 14, cavity 15, heating wire 16, contact post 17, spring seat 18, first spring 19, short rod 20, bushing 21, protrusion 22, recess 23, limiting shell 24, first limiting part 25, second limiting part 26, locking tooth 27, mounting base 28, first fixing frame 29, rounded top 30, straight plate part 31, spring cap 32, second spring 33, connecting port 34, snap-fit ​​hole 35, cut 36, notch 37, second fixing frame 38, fixing post 39, snap-fit ​​part 40.

[0054] like Figure 1-6 As shown in the figure, this embodiment illustrates an electric towel rack, including a vertical rod 1, a conductive component disposed inside the vertical rod 1, the conductive component including a fixed shaft 2 and a conductive wire 3, the conductive wire 3 being embedded in the fixed shaft 2, a conductive ring 4 being disposed outside the fixed shaft 2, the conductive ring 4 being connected to the conductive wire 3; at least one hanging rod 5, the hanging rod 5 being rotatably connected to the vertical rod 1, a heating component 6 disposed inside the hanging rod 5, the heating component 6 being electrically connected to the conductive ring 4, so that the heating component 6 is connected to the conductive wire 3.

[0055] like Figure 3 As shown in Figure 4 / 5, the wire is connected to an external power source, and the conductive wire 3 has at least one connection port 34 for connecting the heating element 6. Specifically, in this embodiment, there are five hanging rods 5, and each hanging rod 5 contains a heating element 6. There are five corresponding connection ports 34 on the conductive wire 3, and each connection port 34 is connected to a heating element 6.

[0056] The working principle of the electric towel rack in this embodiment is as follows: After the conductive wire 3 is energized, since the conductive wire 3 is connected to the heating component 6, the current passes through the heating component 6, and the heating component 6 generates heat. The heat is dissipated onto the hanging rod 5 to heat and dry the towels on the hanging rod 5, preventing the towels from becoming moldy or other problems.

[0057] like Figure 4 As shown in Figure 5, the conductive component in this embodiment also includes a conductive sleeve 7. The fixed shaft 2 includes at least two short shafts 8. Adjacent short shafts 8 are connected by the conductive sleeve 7. Each conductive sleeve 7 is fitted with two conductive rings 4.

[0058] A groove 9 is provided on each side of the outer surface of the conductive sleeve 7. The end of the conductive wire 3 connected to the conductive ring 4 is located inside the groove 9, and the conductive ring 4 is sleeved on the outside of the groove 9. The conductive ring 4 is connected to the conductive wire 3. The conductive ring 4 and the conductive wire 3 can be connected by crimping, welding, or a combination of crimping and welding.

[0059] The connection port 34 of the conductive wire 3 is located within the groove 9, meaning the end of the conductive wire 3 that needs to be connected to the heating element 6 is located within the groove 9. The portion of the conductive ring 4 located on the groove 9 is stamped and deformed, causing the conductive ring 4 to be embedded within the groove 9. Finally, the ends of the conductive ring 4 connected to the conductive wire 3 are crimped together, achieving electrical connection between the conductive wire 3 and the conductive ring 4. In other embodiments, the conductive ring 4 and the conductive wire 3 can also be connected by welding or a combination of crimping and welding.

[0060] The conductive component also includes a central rod 10, which passes through the fixed shaft 2 and the conductive sleeve 7; positioning posts 11 are respectively provided at both ends of the conductive sleeve 7.

[0061] The aforementioned central rod 10 allows the fixed shaft 2 and the conductive sleeve 7 to be connected in series as a whole during installation, facilitating the installation of the conductive components inside the vertical rod 1.

[0062] The fixed shaft 2 has four strip-shaped limiting grooves 12 on its outer surface. In this embodiment, the positioning pins 11 are specifically set to two, and the conductive sleeve 7 is also provided with a through hole 14 for the conductive wire 3 to pass through. In other embodiments, the strip-shaped limiting grooves 12 can also be set as strip-shaped limiting holes.

[0063] Four strip-shaped limiting grooves 12 are evenly distributed on the outer wall of the fixed shaft 2. Two opposing strip-shaped limiting grooves 12 are used to cooperate with the positioning post 11 of the conductive sleeve 7 to prevent the conductive sleeve 7 from rotating relative to the short shaft 8 during assembly. The other two opposing strip-shaped limiting grooves 12 are used to lay the conductive wire 3. In this embodiment, five short shafts 8 are provided, and the short shafts 8 are covered with an insulating sleeve (not shown in the figure).

[0064] like Figure 6 As shown in Figure 7, the electric towel rack also includes at least one connecting sleeve 13. The connecting sleeve 13 has a through hole 14 and two cavities 15 inside. The connecting sleeve 13 is sleeved on the outside of the conductive sleeve 7 through the through hole 14. The through hole 14 is connected to the two cavities 15 respectively.

[0065] The heating element 6 includes a heating wire 16, with contact posts 17 connected to both ends of the heating wire 16. The contact posts 17 at both ends of the heating wire 16 are connected to the conductive coil 4 through two cavities 15 respectively. A spring seat 18 is provided in the cavity 15, and a first spring 19 is provided between the spring seat 18 and the contact post 17.

[0066] In the above structure, the heating wire 16 and the contact post 17 are connected by riveting. The contact posts 17 at both ends of the heating wire 16 enter the two cavities 15 from the bottom of the connecting sleeve 13, and contact the conductive ring 4 in the through hole 14 through the cavity 15, thereby realizing the connection between the heating wire 16 and the conductive wire 3.

[0067] The spring seat 18 is threaded or snapped into the inner wall of the cavity 15. The first spring 19 applies elastic force to the contact post 17, so that the contact post 17 can be effectively connected to the conductive coil 4, preventing the contact post 17 from disconnecting from the conductive coil 4 due to thermal expansion and contraction of the material, thereby ensuring the stability of the connection between the heating component 6 and the conductive coil 4.

[0068] Furthermore, such as Figure 2 As shown in Figure 8, the vertical rod 1 includes at least one short rod 20. In this embodiment, the short rod 20 has five segments. Adjacent short rods 20 are connected by bushings 21, and the short rods 20 are rotatable relative to the bushings 21. The hanging rod 5 is fixedly connected to the short rods 20, specifically by welding.

[0069] like Figure 8 As shown in / 9 / 10 / 11 / 12, a limiting shell 24 is provided inside the vertical rod 1. The limiting shell 24 is a cylindrical shell with openings at both ends. At least one notch 37 is provided at the bottom of the limiting shell 24 for connecting the connecting sleeve 13 and the conductive sleeve 7. One side of the notch 37 is an opening, and the other side of the notch 37 is a first limiting part 25. A cut 36 is provided on the top of the limiting shell 24 along its axial direction. The cut 36 and the first limiting part 25 are located on the same side as the second limiting part 26. The inner wall of the bushing 21 is provided with a locking tooth 27, which engages with the cut 36.

[0070] The retaining teeth 27 on the inner wall of the bushing 21 engage with the notch 36 of the limiting shell 24, preventing the bushing 21 from rotating relative to the limiting shell 24. The bushing 21 can only move axially within the limiting shell 24. The fixedly connected short rod 20 and hanging rod 5 can rotate relative to the bushing 21, and the rotation of the hanging rod 5 drives the connecting sleeve 13 to rotate. When the hanging rod 5 rotates to the point where its end contacts the first limiting part 25, the contact point between the contact post 17 and the conductive ring 4 is A. When the hanging rod 5 rotates to the point where its end contacts the second limiting part 26, the contact point between the contact post 17 and the conductive ring 4 is B. The trajectory of the contact points is the arc segment AB.

[0071] The first limiting part 25 and the second limiting part 26 of the limiting shell 24 ensure that the contact post 17 is always in contact with the conductive ring 4 during the rotation of the hanging rod 5, thus guaranteeing the normal connection between the heating element 6 and the conductive wire 3 and ensuring the normal operation of the electric towel rack. During rotation, the elastic force of the first spring 19 acting on the contact post 17 also helps to ensure the connection between the heating element 6 and the conductive wire 3.

[0072] like Figure 13 As shown, the connecting sleeve 13 has protrusions 22 at both ends, and the hanging rod 5 has a corresponding recess 23 at its end. The protrusions 22 and the recesses 23 cooperate with each other. In this embodiment, the cooperation between the protrusions 22 and the recesses 23 enables the hanging rod 5 to rotate, thereby driving the connecting sleeve 13 to rotate.

[0073] like Figure 14 As shown, each end of the vertical rod 1 is connected to a mounting base 28 via a bushing 21, and both ends of the limiting shell 24 are fixedly connected to the mounting base 28. Specifically, the two ends of the limiting shell 24 are fixedly connected to the mounting base 28 by bolts. The electric towel rack is mounted on the wall via the mounting bases 28 at both ends.

[0074] like Figure 15 As shown in Figures 16, 17, and 18, a first fixing frame 29 and a second fixing frame 38 are respectively connected to both ends of the central rod 10. The first fixing frame 29 is generally T-shaped with a dome. The first fixing frame 29 includes a dome 30 and a straight plate 31 connected to each other. The dome 30 is engaged with the cutout 36 of the limiting shell 24. The limiting shell 24 also has engagement holes 35 at both ends, and the straight plate 31 is engaged with the engagement holes 35. The second fixing frame 38 includes a fixing post 39 and an engagement part 40. The fixing post 39 is threaded to the central rod 10, and the engagement part 40 is engaged between the cutout 36 and the engagement hole 35.

[0075] The dome 30 and the notch 36 are engaged to restrict the rotation of the first fixing frame 29 relative to the limiting shell 24, and the straight plate 31 and the engaging hole 35 are engaged to restrict the first fixing frame 29 from moving axially relative to the limiting shell 24.

[0076] One end of the central rod 10 is screwed to the second fixing frame 38; the other end of the central shaft passes through the first fixing frame 29 and is provided with a spring cap 32, and a second spring 33 is provided between the spring cap 32 and the adjacent first fixing frame 29.

[0077] The second spring 33 acts on the first fixing bracket 29, causing the straight plate portion 31 to abut against the snap-fit ​​hole 35, thus fixing the first fixing bracket 29 inside the limiting shell 24. In this embodiment, the center column 10 is fixed inside the limiting shell 24 by snapping the first fixing bracket 29 and the second fixing bracket 38 with the limiting shell 24 respectively.

[0078] The above descriptions are merely embodiments of the present invention, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the present invention or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
