[0039] In the claims, description and accompanying drawings of this utility model, the terms "comprising", "having", and variations thereof are used to mean "including but not limited to".

[0040] See Figures 1 to 6 ,like Figure 1 As shown, a rotary press controller for an electric towel rack integrates rotary adjustment and press confirmation functions. The controller includes a rotary component, a display component, a main body component, an elastic element 12, a main body seal 10, and an external component.

[0041] Rotating components, such as Figure 1 , Figure 4As shown, the device includes a rotating housing 1 and two induction magnets 2 disposed inside the rotating housing 1. The induction magnets 2 are symmetrically distributed circumferentially on the inner wall of the rotating housing 1 to optimize the magnetic field distribution and improve the accuracy of rotation detection. Specifically, axially extending mounting grooves 15 are provided on both symmetrical sides of the inner wall of the rotating housing 1 for securely mounting the induction magnets 2. The rotating housing 1 is designed for manual rotation by the user. The design of the rotating housing 1 conforms to ergonomic principles, facilitating user operation and providing a good feel and appearance.

[0042] Display components, such as Figure 1 , Figure 3 and Figure 4 As shown, it includes a display panel 3, a display circuit board 4, and an annular seal 5.

[0043] The display panel 3 has a transparent flat surface, which makes it easy for users to view information from the display circuit board 4, and it also has a pressing function.

[0044] The display panel 3 is coaxially mounted and rotatably connected to the rotating housing 1. Specifically, as follows: Figure 3 As shown, the rotating outer shell 1 is fitted onto the display panel 3. The periphery of the display panel 3 is provided with a radially protruding flange 33, and the inner wall of the rotating outer shell 1 is provided with a corresponding radially protruding stepped surface 18. The display panel 3 abuts against the stepped surface 18 of the rotating outer shell 1 through the flange 33, so that the surface of the display panel 3 and the rotating outer shell 1 are flush, which is both aesthetically pleasing and convenient for pressing operation.

[0045] like Figure 4 As shown, several annular grooves 31 extending axially are provided on the outer circumferential side of the display panel 3, which cooperate with the elastic member 12.

[0046] Display circuit board 4, fixed inside display panel 3, integrates Hall element and tactile switch 42. The Hall element is magnetically coupled to sensing magnet 2 to detect the rotation position of rotating housing 1 in real time. Specifically, when the user rotates housing 1, it causes a change in the magnetic field of sensing magnet 2. This change is immediately captured by the Hall element on display circuit board 4, causing a synchronous change in the voltage signal output by the Hall element. Subsequently, this voltage signal is transmitted to electronic control circuit board 8 and display circuit board 4 for processing, completing the recognition and response to the rotation operation.

[0047] The tactile switch 42 enables a press-to-confirm function. For example... Figure 3As shown, a first protrusion 41 is located in the middle of the display circuit board 4, facing the main component, and a tactile switch 42 is located in the center of the first protrusion 41. In addition, the display circuit board 4 also integrates a digital tube, which serves as a temperature control panel to display temperature and time information, and an ambient light is provided around the temperature number. Different colored halos are displayed according to different temperature ranges. In this embodiment, the colors of the halos are as follows: orange for drying mode, blue for constant temperature mode, and red for heating mode.

[0048] An annular seal 5 is installed at the mating surface of the display circuit board 4 and the display panel 3. Its function is to prevent liquid or dust from entering the display assembly and protect the internal circuitry. Specifically, the annular seal 5 adopts an O-ring design and is installed in the first groove at the center of the periphery of the display circuit board 4 to ensure a reliable sealing effect.

[0049] Main components, such as Figure 1 , Figure 3 and Figure 5 As shown, it includes a main outer shell, an electronic control circuit board 8, a fixed inner shell 9, and an interface seal 11.

[0050] The main outer casing includes a detachably connected outer casing body 6 and a back cover 7. The outer casing body 6 has a cylindrical structure, and the back cover 7 is located at the end of the outer casing body 6 away from the rotating outer casing 1. Specifically, as shown... Figure 1 As shown, the inner wall of the outer shell body 6 is provided with several circumferentially extending locking blocks (not shown in the figure), and the back cover plate 7 is provided with locking grooves 75 corresponding to the locking blocks, so that the outer shell body 6 and the back cover plate 7 can be detachably connected.

[0051] like Figure 1 and Figure 3 As shown, a cover sealing ring 74 is installed in a groove on the side of the back cover 7. The cover sealing ring 74 seals the interface between the main body shell and the back cover 7 circumferentially, which can enhance the water sealing performance of the rear of the controller and prevent external liquid from entering the controller through the interface between the cover and the main body shell. Specifically, the cover sealing ring 74 adopts an O-ring design and is installed in the second groove at the center of the periphery of the back cover 7.

[0052] like Figure 3 As shown, the main body housing has a conductive post 71 near the tactile switch 42, used to trigger the tactile switch 42 when the display panel 3 is pressed. Specifically, the conductive post 71 is installed at the end of the back cover 7 facing the display circuit board 4. The conductive post 71 passes through a through hole in the center of the electronic control circuit board 8 and is close to the display circuit board 4. A pressing gap is provided between the conductive post 71 and the tactile switch 42, and the pressing gap is equal to the pre-compression amount of the main body seal 10. The axial length of the conductive post 71 is designed according to the pre-compression amount of the main body seal 10 during mold opening.

[0053] like Figure 1As shown, the back cover 7 integrates acoustic components, including a microphone 72 and a speaker 73. These acoustic components are signal-connected to the display circuit board 4 and electrically connected to the electronic control circuit board 8. This integrated acoustic component design on the back cover 7 enables voice interaction and enhances the controller's versatility.

[0054] The electronic control circuit board 8 is fixed inside the main housing. Specifically, the electronic control circuit board 8 is fixed to the housing body 6 by the first self-tapping screw 81. The electronic control circuit board 8 is electrically connected to the display circuit board 4 and is used to process rotation and pressing signals.

[0055] Fixed inner shell 9, such as Figure 5 As shown, it is a hollow structure composed of an inner annular wall 91 and an outer annular wall 95 that run vertically through the body, and is fixed to one end of the rotating outer shell 1 inside the main body shell. Specifically, the outer annular wall 95 is provided with a number of side holes 96 around its perimeter, and the outer shell body 6 is provided with a number of radially extending protrusions 60 that cooperate with the side holes 96, so that the outer shell body 6 and the fixed inner shell 9 can be detachably connected.

[0056] The fixed inner shell 9 is circumferentially limited and connected to the display panel 3 and the display circuit board 4 to prevent relative rotation. Specifically, the top periphery of the fixed inner shell 9 has two positioning through holes 94, and the bottom of the display panel 3 has axially extending positioning protrusions 32 corresponding to the positioning through holes 94, so that the fixed inner shell 9 and the display panel 3 are connected to prevent rotation. The inner annular wall 91 has two positioning blocks 92 facing the display circuit board 4, a square positioning block 92 and a round positioning block 92. The display circuit board 4 has a slot (not shown in the figure) corresponding to the positioning blocks 92, and the positioning blocks 92 pass through the slots to prevent rotation between the fixed inner shell 9 and the display circuit board 4. The square and round positioning blocks 92 can prevent incorrect insertion of the circuit board.

[0057] like Figure 1 , Figure 3 and Figure 5 As shown, the interface seal 11 is installed between the fixed inner shell 9 and the display panel 3 to enhance the sealing performance between the two. Specifically, the interface seal 11 adopts an O-ring design and is installed in the third groove at the center of the inner circumference of the fixed inner shell 9 to ensure reliable sealing.

[0058] Elastic element 12, such as Figure 1 , Figure 3 and Figure 4 As shown, the elastic element 12 is fixed to the inner wall of the rotating housing 1. When the rotating housing 1 is rotated, the elastic element 12 periodically abuts against the annular groove 31. Specifically, the elastic element 12 is a spring, and the inner wall of the rotating housing 1 is provided with a retaining seat 16. The elastic element 12 is radially inserted into the retaining seat 16 and abuts against the display panel 3. The radial insertion of the spring into the retaining seat 16 and abutting against the display panel 3 provides tactile feedback during rotation, allowing the user to clearly perceive the rotation position and enhancing the feel and accuracy of operation.

[0059] The main sealing element 10 is installed between the main outer shell and the fixed inner shell 9, is suitable for compression, and has a pre-compression amount. For example... Figure 5 As shown, the main sealing element 10 is a double-lip sealing ring, including an inner lip 101 and an outer lip 102. The inner lip 101 protrudes axially from the outer lip 102, and the fixed inner shell 9 is snapped onto the inner lip 101. The inner lip 101 is adapted to be compressed and provides a rebound force for pressing the display panel 3. The outer lip 102 is snapped onto the main outer shell for sealing between the main outer shell and the fixed inner shell 9. The main sealing element 10 is adapted to be compressed and has a pre-compression amount, which ensures the sealing effect and provides the necessary stroke margin for the pressing operation. In this embodiment, the pre-compression amount is approximately 1.3 mm.

[0060] Specifically, such as Figure 3 As shown, the outer lip 102 has an annular first groove 103 around its periphery, suitable for sealing engagement with the annular first protrusion 62 extending axially from the outer shell body 6. The inner lip 101 has an annular second groove 104 around its periphery, suitable for sealing engagement with the annular second protrusion 93 extending axially from the inner wall of the fixed inner shell 9. The outer wall of the fixed inner shell 9 is fitted onto the outer lip 102 and has a clearance gap with the outer shell body 6, and is suitable for approaching the outer shell body 6 when the inner lip 101 is compressed.

[0061] External components, such as Figure 1 and Figure 6 As shown, it includes a power cord 13 and an aviation connector 14.

[0062] The power cord 13 is an external plug power cord. The outer shell body 6 has a side hole 96. The power cord 13 passes through the silicone plug 66 into the side hole 96 of the outer shell body 6 and is pressed and sealed by the first buckle 67 and two second self-tapping screws 68.

[0063] The aviation connector 14 is inserted into the side wall hole 63 of the housing body 6 and radially locked by the second latch 69. Specifically, the housing body 6 has a radially extending hole 63, and a copper nut 64 is installed on the side wall of the hole 63. The copper nut 64 is assembled in the injection molded body 6 during injection molding. The aviation connector 14 is inserted into the hole 63, and after the elastic latch is installed in place, it is radially locked by the copper nut 64.

[0064] In this embodiment, the external plug power cord 13 is connected to an external power socket, and the aviation connector 14 is connected to the plug of the electric towel rack. The design of the external components (power cord 13 and aviation connector 14) takes into account the ease of assembly and the reliability of sealing, preventing external liquids from entering the interior of the housing body 6 through the side hole 96 and the channel 63.

[0065] In this embodiment, the rotary press controller achieves rotation adjustment by rotating the housing 1 and the display panel 3, combined with the magnetic field coupling between the Hall element on the display circuit board 4 and the sensing magnet 2. Simultaneously, the press confirmation function is achieved through the interaction of the tactile switch 42 on the display circuit board 4 and the conductive post 71 on the main housing, integrating rotary adjustment and press confirmation into a combined operation. The annular groove 31 on the outer edge of the display panel 3 engages with the elastic element 12 on the inner wall of the rotating housing 1, generating periodic contact during rotation and providing clear tactile feedback, facilitating user perception of the rotation position. The multiple sealing structure of the annular seal 5, the main body seal 10, and the interface seal 11 ensures the waterproof performance of the controller's internal circuitry, improving product reliability and lifespan. The pre-compression design of the main body seal 10 ensures both sealing effectiveness and provides necessary travel margin for the pressing operation.
