[0035] An embodiment of this application discloses an electric kettle with a flexible control board. The electric kettle includes an outer shell 1, a kettle body 2, an annular light-transmitting element 3, a light guide bracket 4, and a flexible control board 5. The electric kettle is placed on a base 6. After the base 6 is connected to a power source and powered on, images or numbers can be projected onto the annular light-transmitting element 3. The images indicate button functions, and the numbers indicate heating temperature, time, or settings, etc. Pressing the touch area on the annular light-transmitting element 3 can trigger the corresponding button on the flexible control board 5, and the electric kettle enters the working mode.
[0036] like Figure 1-5 As shown, the kettle body 2 is set inside the outer shell 1. The kettle body 2 can be used to hold water or other liquids such as coffee, juice, etc., and can be heated. The annular light-transmitting element 3 is embedded in the bottom of the outer shell 1. A light guide bracket 4 is provided on the inner side of the annular light-transmitting element 3. The light guide bracket 4 is set towards the annular light-transmitting element 3. A flexible control plate 5 is provided on the light guide bracket 4. The light guide bracket 4 fixes and limits the flexible control plate 5 so that the shape of the flexible control plate 5 fits the annular light-transmitting element 3. Several LED beads 51 are provided on the flexible control plate 5. The light emitted by the LED beads 51 enters the annular light-transmitting element 3 and shines outward, forming numbers or images on the annular light-transmitting element 3.
[0037] like Figure 6 , 7 As shown, the light guide bracket 4 has several round holes 41, grooves 42 and digital slots 43. Preferably, in this embodiment, the digital slots 43 are located in the middle of the light guide bracket 4. The digital slots 43 are in the shape of an "8" and there are three of them. There are four grooves 42, which are respectively opened on the side and bottom of the digital slots 43 to guide the light of the LED beads 51. There are six round holes 41, which are symmetrically arranged on both sides of the digital slots 43. Of course, the number and orientation of the round holes 41, grooves 42 and digital slots 43 can be set according to the design needs. This embodiment is not the only solution.
[0038] like Figure 7 As shown, a limiting bracket 46 is fastened to the light guide bracket 4. The light guide bracket 4 is provided with a first slot 44, and the limiting bracket 46 is provided with a corresponding first buckle 47. The light guide bracket 4 and the limiting bracket 46 are fastened together to fix the flexible control plate 5. The light guide bracket 4 is provided with a number of second buckles 45, and the annular light-transmitting element 3 is provided with a second slot 31. The light guide bracket 4 is fastened to the annular light-transmitting element 3 by the second buckles 45.
[0039] like Figure 3 , Figure 7 As shown, the outer shell 1 is provided with a plurality of snap-fit parts 12 in a circumferential direction. The annular light-transmitting element 3 is snapped into the snap-fit parts 12 and fixed so that the annular light-transmitting element 3 is fitted into the bottom of the outer shell 1.
[0040] like Figure 7 As shown, multiple LED beads 51 are distributed on the flexible control board 5. The flexible control board 5 is fixed within the light guide bracket 4. The LED beads 51 are distributed in the round hole 41, the groove 42 and the digital slot 43 respectively. Several springs 52 are welded on the flexible control board 5. The springs 52 pass through the round hole 41 on the light guide bracket 4 and abut against the inner wall of the annular light-transmitting element 3.
[0041] like Figure 8 As shown, the flexible control board 5 is equipped with a trigger button 53. After assembly, one end of the spring 52 abuts against the inner wall of the annular light-transmitting component 3, and the other end of the spring 52 abuts against the trigger button 53. When the spring 52 is subjected to force, it triggers the trigger button 53; simultaneously... Figure 8 As shown, after assembly, the LED beads 51 are respectively set in the round hole 41, the groove 42 and the number slot 43.
[0042] The touch function of the electric kettle is realized by the spring 52 triggering the button on the flexible control board 5. In this embodiment, the material of the annular light-transmitting part 3 is a non-rigid body, such as high polymer PC. When the corresponding position on the outer wall of the annular light-transmitting part 3 is pressed, the annular light-transmitting part 3 is indented by force, causing the spring 52 to contract. The spring 52 tightens and triggers the trigger button 53 on the flexible control board 5. The trigger button 53 is connected to the control chip. The trigger button 53 inputs a signal to realize the touch operation.
[0043] like Figure 3 As shown, a heating tube 21 is provided at the bottom of the kettle body 2. Couplers 61 are provided on the bottom surface of the electric kettle and the base 6 respectively. The power cord of the base 6 is connected to the power supply. The electric kettle inputs electrical energy through the coupler 61, which powers the heating tube 21 to heat the kettle body 2, thereby heating the water or other liquid inside the kettle body 2.
[0044] Heating element 21 is connected to relay RLY1. Relay RLY1 is activated to turn on heating element 21. Figure 9As shown, the coil of relay RLY1 is connected to a DC voltage, which is converted into a DC voltage output by power module 13, as follows. Figure 10 As shown, the other end of the coil of relay RLY1, RLY, is connected to the collector of transistor Q1. The emitter of transistor Q1 is connected to the ground point. The base of transistor Q1 is connected to resistor R5 and then to pin 14 of control chip IC1. The control chip outputs a signal to turn on transistor Q1, and relay RLY1 is energized and engaged.
[0045] like Figure 10 , Figure 11 As shown, the flexible control board 5 is equipped with a control chip IC1 and an LED driver chip IC2. The LED driver chip IC2 is connected to the LED beads 51 on the flexible control board 5 and outputs voltage to light up the LED beads 51. The control chip IC1 is connected to the LED driver chip IC2 and transmits data between them. The control chip IC1 controls the output voltage of the LED driver chip to light up the LED beads 51.
[0046] like Figure 10 As shown, pin 9 of control chip IC1 is labeled po_data. Pin 9 of control chip IC1 is connected to pin 16 of LED driver chip IC2. There are six trigger keys 53, namely K1, K2, K3, K4, K5, and K6, labeled pi_key1, pi_key2, pi_key3, pi_key4, pi_key5, and pi_key6. The six trigger keys 53 are connected to pins 15, 13, 4, 5, 6, and 7 of control chip IC1, respectively. Pins 2, 3, 11, and 12 of control chip IC1 are labeled po_rgb_r, po_rgb_g, po_rgb_rl, and po_rgb_gl, respectively, and are connected to the red and green indicator lights of the electric kettle. Pin 10 of control chip IC1 is labeled pod_vrt, which outputs a signal to control the alarm of the electric kettle.
[0047] like Figure 10 , Figure 11 As shown, the positive terminals of LED beads 51 are divided into seven groups: pdsp_a, pdsp_b, pdsp_c, pdsp_d, pdsp_e, pdsp_f, and pdsp_g, which are connected to pins 8, 6, 3, 2, 4, 7, and 5 of LED driver chip IC2, respectively. The negative terminals of LED beads 51 are divided into seven groups: pdsp_1, pdsp_2, pdsp_3, pdsp_4, and pdsp_5, which are connected to pins 13, 12, 11, 15, and 14 of LED driver chip IC2, respectively. The output voltage of LED driver chip illuminates LED beads 51.
