[0038] like Figure 1 , 2 As shown, the electric kettle 001 includes a kettle body 100, a base 200, a power switch 300, and an indicator light 400. The base 200 is located at the bottom of the kettle body 100 and has a wiring terminal 210.

[0039] like Figure 3 , 4 As shown, the power switch 300 includes a connecting part 310 rotatably connected to the base 200 and an operating part 320 for user operation. The connecting part 310 is located inside the base 200, and multiple slots 330 are respectively provided on opposite sides of the connecting part 310. An indicator light 400 is provided on the operating part 320, and the power cord 410 of the indicator light 400 is embedded in the multiple slots 330 and connected to the terminal block 210.

[0040] like Figure 4 As shown, in some embodiments of this utility model, the card slot 330 extends in the vertical direction.

[0041] Continue reading Figure 3 , 4 In some embodiments of this utility model, the connecting part 310 is U-shaped with two connecting arms 311 and multiple slots 330 disposed on the two connecting arms 311. The power cord 410 of the indicator light 400 consists of two wires, which are respectively connected to the terminal block 210 via the two connecting arms 311 of the connecting part 310. Each connecting arm 311 is provided with multiple slots 330, which are disposed opposite to the other connecting arm 311. A rotating shaft 350 is disposed opposite to the other connecting arm 311 on the side of the connecting arm 311 closest to the other connecting arm 311. A corresponding rotating hole is provided on the base 200 to cooperate with the rotating shaft 350, so that the switch 300 is rotatably connected to the base 200.

[0042] like Figure 1 , 2As shown, a clearance hole is provided on the kettle body 100, and the switch 300 extends from inside the kettle body 100 through the clearance hole to the outside of the kettle body 100. The user can turn the electric heating function of the electric kettle 001 on or off by moving the switch 300 up and down.

[0043] This utility model sets the connecting part 310 in a U-shape so that the two power lines 410 of the indicator light 400 start from the operating part 320 and are arranged along the two connecting arms 311 on both sides. Each power line 410 is fixed by setting multiple slots 330 on each connecting arm 311.

[0044] The advantages of this design are twofold. First, the U-shaped design allows the two power cords 410 to wind around to both sides and connect to the terminal block 210. Second, the slot 330 forces the power cord 410 to run along the outside of the connecting arm 311, away from heating elements such as the heating plate 220.

[0045] Secondly, the power cord 410 is secured by multiple slots 330 on opposite sides of the connecting portion 310. The opening of the slot 330 is smaller than the diameter of the power cord 410, allowing the power cord 410 to be secured within the slot 330. Simultaneously, the U-shaped dual-wire separation design further reduces the probability of the power cord 410 coming into contact with high-temperature components.

[0046] Those skilled in the art will understand that when the power cord 410 is secured in the slot 330, it can still slide within the slot 330 along its length. This facilitates the assembly of the indicator light 400, because during the manufacturing process of the electric kettle 001, the distribution of the power cord 410 needs to be finely adjusted to prevent it from interfering with other components or from touching the heating element, such as the heating plate 220. The slot 330 allows for fine-tuning of the power cord 410 along its length, enabling workers to adjust the tightness of the power cord 410 during assembly and prevent interference with other components.

[0047] Continue reading Figure 4 In some embodiments of this utility model, at least one upper edge of a connecting arm 311 is provided with at least one slot 330.

[0048] Continue reading Figure 3 In some embodiments of the present invention, the connecting part 310 further includes a positioning groove 340 for accommodating the power cord 410, the positioning groove 340 being disposed between the slot 330 closest to the operating part 320 and the operating part 320.

[0049] Continue reading Figure 3In some embodiments of this utility model, the positioning groove 340 is disposed on the lower edge of the connecting arm 311, and the groove opening of the positioning groove 340 faces downward.

[0050] In some embodiments of this utility model, the extension length of the card slot 330 can be selected from any value from 0.5mm to 3mm. For example, the extension length of the card slot 330 can be any feasible value such as 0.5mm, 0.8mm, 1.5mm, 2mm, and 3mm.

[0051] Furthermore, the extension length of the card slot 330 can be selected from any value between 1 mm and 2 mm. For example, the extension length of the card slot 330 can be 1 mm, 1.2 mm, 1.4 mm, 1.6 mm, and 2 mm, etc.

[0052] Those skilled in the art will understand that when the length of the 330 slot is too short (<0.5mm), the wire is only held in place by the edge of the slot, resulting in concentrated local stress. Long-term use can easily lead to the insulation layer being cut (especially when the switch is frequently pressed). Conversely, if the length is too long (>3mm), excessive bending of the wire during assembly may cause the internal copper core to break. The 0.5mm-3mm length design structurally avoids damage to the wire insulation layer or breakage of the copper core, reducing the risk of short circuits and leakage.

[0053] like Figure 4 As shown, in some embodiments of the present invention, the operation part 320 defines a receiving cavity 321 facing the connection part 310 for receiving the indicator light 400.

[0054] Continue reading Figure 4 In some embodiments of this utility model, the extension directions of each slot 330 are parallel.

[0055] Continue reading Figure 4 In some embodiments of this utility model, each connecting arm 311 is provided with two slots 330. The slot 330 closer to the operating part 320 is higher in the vertical direction than the slot 330 farther from the operating part 320. The two slots 330 of each connecting arm 311 are distributed with the upper one higher than the lower one. After the power cord 410 is inserted, it forms a bend and is locked by friction.

[0056] like Figure 3As will be understood by those skilled in the art, this utility model provides two slots 330 on each connecting arm 311, and a positioning groove 340 is positioned between the slot 330 closest to the operating part 320 and the operating part 320. The positioning groove 340 is located on the lower edge of the connecting arm 311, with its opening facing downwards. An indicator light 400 is disposed in the receiving cavity 321. The power cord 410 of the indicator light 400 extends from the receiving cavity 321, passes through the lower positioning groove 340, and exits to the outside of the connecting part 310. The power cord 410 then ascends and is fixed via the slot 330 closest to the operating part 320, and is further fixed via the slot 330 furthest from the operating part 320. The power cord 410 between the two slots 330 naturally bends upwards. After passing through the slot 330 furthest from the operating part 320, the power cord 410 naturally bends downwards.

[0057] Alternatively, the power cord 410 can be locked by pulling the portion of the power cord 410 between the two slots 330. It is understood that when the power cord 410 between the two slots 330 is pulled tight, since the two slots 330 extend in the same direction (both vertically), the power cord 410 bends at the two slots 330, generating significant friction between the power cord 410 and the slots 330, thus locking the power cord 410 in place.

[0058] Continue reading Figure 3 Those skilled in the art will understand that by using the locking action of the two slots 330 on the power cord 410, the length of the section of power cord 410 between the slot 330 furthest from the operating part 320 and the terminal 210 can be flexibly adjusted. During the production and assembly of the electric kettle 001, the power cord 410 is generally designed to be slightly longer to facilitate the installation of the indicator light 400. A longer power cord 410 can bend freely within the base 200, easily touching heating elements such as the heating plate 220, causing the power cord 410 to burn out. By using the locking action of the two slots 330 on the power cord 410, the assembler can adjust the length of the section of power cord 410 between the slot 330 furthest from the operating part 320 and the terminal 210, and then use the two slots 330 to lock the power cord 410 in place.

[0059] In some embodiments of this utility model, the base 200 also includes a steam-type automatic power-off switch, a kettle socket, a heating plate 220, a thermostat, and a thermal fuse.

[0060] When the water in the electric kettle 001 boils, the steam generated is sent through a steam pipe to a rubber tube at the bottom, and then by a steam guide plate to the steam-type automatic power-off switch. The power-off spring inside the steam-type automatic power-off switch deforms due to heat, causing the switch to activate. This leverages the lever principle to activate the power switch, thus achieving the function of automatically cutting off the power when the water boils.

[0061] Under normal temperature conditions, the thermostat is closed to ensure that the circuit can be conducted. When the first automatic steam shut-off switch fails, the water will continue to be heated and the temperature will be maintained at 100℃ until it boils dry. At this time, the temperature of the kettle body exceeds 100℃, and the bimetallic strip on the thermostat will deform due to heat and push the contact to disconnect. This is the second protection, namely the anti-dry-boil protection.

[0062] Among them, when the electric kettle 001 is too hot or has a serious short circuit, the thermal fuse will come into play, melting and cutting off the power, thus providing protection.

[0063] In some other embodiments of this utility model, the thermal fuse may be omitted from the base 200.

[0064] In some embodiments of this utility model, the switch 300 further includes a lamp wire fixing bracket. After the indicator light 400 is installed into the receiving cavity 321, the lamp wire fixing bracket is then installed into the receiving cavity 321. The lamp wire fixing bracket and the receiving cavity 321 are interference-fitted. The lamp wire fixing bracket is used to prevent the indicator light 400 from falling out of the receiving cavity 321.

[0065] The working principle of electric kettle 001 is as follows:

[0066] After the power is connected, the steam-type automatic power-off switch closes, and the positive terminal of the power supply, the thermostat, the thermal fuse, the heating plate 220, and the negative terminal of the power supply sequentially form a circuit. The heating plate 220 begins to heat, and the indicator light 400, connected in parallel to the heating plate 220, illuminates. When the water boils, the steam-type automatic power-off switch cuts off the power, the indicator light 400 goes out, and the electric kettle 001 stops heating.

[0067] The electric kettle 001 provided by this utility model has two power cords 410 of the indicator light 400 running from both sides of the switch 300. After the two power cords 410 are led out from the receiving cavity 321, they first pass through the positioning groove 340 on the lower side to the outside of the connecting part 310, and then are fixed by multiple slots 330 on the outside of the connecting part 310. By tightening the power cord 410 portion between the multiple slots 330, the power cord 410 can be locked. This not only reliably fixes the power cord 410 to prevent it from loosening and contacting the high-temperature heating element, but also allows for adjustment of the arrangement position of the power cord 410.

[0068] like Figure 1As shown, this utility model also provides an electric kettle assembly 010, which includes the above-mentioned electric kettle and charging base 002.

[0069] The technical solution of this utility model has been described in conjunction with several embodiments above. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is not limited to these specific embodiments. Without departing from the technical principles of this utility model, those skilled in the art can disassemble and combine the technical solutions in the above embodiments, and can also make equivalent changes or substitutions to the relevant technical features. Any changes, equivalent substitutions, improvements, etc., made within the technical concept and / or technical principles of this utility model will fall within the protection scope of this utility model.
