A connecting gasket 23 is arranged between the stainless steel top tube 22 and the horizontal position of the extended inner ring 13. A heat-conducting bottom plate 24 is fixedly installed on the bottom of the stainless steel top tube 22. The waterproof mechanism 15 includes a solid sealing ring 151. The inner ring of the solid sealing ring 151 is fixedly connected to the outer wall of the inner liner extension ring 14. Three annular sealing ribs 152 are evenly fixedly installed on the outer wall of the solid sealing ring 151. The inner liner extension ring 14 uses the three annular sealing ribs 152 to have an interference fit with the extended inner ring 13 of the inner ring of the plastic pot body shell 11.
[0023] A solid sealing ring 151 is provided between the plastic kettle body shell 11 and the inner ring of the stainless steel liner 12, and the inner liner extension ring 14 to improve the waterproof effect. At the same time, three annular sealing ribs 152 are added to the outer wall of the solid sealing ring 151, so that the inner liner extension ring 14 can achieve an interference fit with the inner ring of the inner ring 13 at the bottom of the inner ring of the plastic kettle body shell 11 by using the annular sealing ribs 152 on the outer wall of the solid sealing ring 151, thereby further improving the waterproof effect between the plastic kettle body shell 11 and the stainless steel liner 12 to prevent water leakage.
[0024] like Figure 4 As shown, the pot cover mechanism 4 includes a plastic top cover 41, a stainless steel bottom plate 42 is fixedly installed on the bottom of the plastic top cover 41, a sealing rubber ring 43 is fixedly installed on the outer wall of the stainless steel bottom plate 42, and a water outlet groove 44 is opened on the right side of the sealing rubber ring 43, and the water outlet groove 44 is located on the side of the pot spout of the pot body mechanism 1;
[0025] When pouring water, the plastic top cover 41 on the top is clamped on the uppermost part of the inner ring of the stainless steel liner 12 by the stainless steel bottom plate 42, and cooperates with the extrusion between the sealing rubber ring 43 on the outer wall of the stainless steel bottom plate 42 and the inner ring of the stainless steel liner 12, so as to realize the firm closing of the overall pot cover mechanism 4, and at the same time, by utilizing the water outlet groove 44 opened on the right side of the sealing rubber ring 43, it is not necessary to open the stainless steel bottom plate 42 and the sealing rubber ring 43 when pouring water, so that the water source can be poured out from the spout structure of the pot body mechanism 1 only through the water outlet groove 44, and due to the extrusion and sealing between the sealing rubber ring 43 and the inner ring of the stainless steel liner 12, the water source in the pot is prevented from leaking out from the side of the stainless steel bottom plate 42 when pouring.
[0026] like Figure 5 As shown, a power supply built-in socket 211 is fixedly installed on the rear side of the inner wall of the plastic bottom shell 21, and the rear end of the power supply built-in socket 211 penetrates to the rear side of the plastic bottom shell 21, and the output end of the power supply built-in socket 211 is electrically connected to two power-carrying wires 212, and the output end of the upper power-carrying wire 212 is electrically connected to a power-connecting copper ring 213, and the power-connecting copper ring 213 is fixedly connected to the bottom left side of the heat-conducting chassis 24, and a power knob 214 is provided on the front side of the plastic bottom shell 21. The output end of a power-on wire 212 at the bottom is fixedly connected to the rear end of the power-on knob 214, and the output end of the rear side of the power-on knob 214 is electrically connected to a control wire 215, and the output end of the control wire 215 is electrically connected to a second power-on copper ring 216, and the second power-on copper ring 216 is fixedly connected to the right side of the bottom of the heat-conducting chassis 24. The power-on wire 212 connected to the rear side of the control wire 215 and the power-on knob 214 can be powered on and off by rotating the power-on knob 214;
[0027] When water needs to be boiled, the power cord is inserted into the built-in power supply socket 211 and penetrates the rear part of the plastic bottom shell 21 to turn on the power. The power-connecting copper ring 1 213 at the output end of one power-connecting wire 212 and the power-connecting copper ring 216 at the output end of another power-connecting wire 212 are used to connect the positive and negative poles to the bottom interface of the heat-conducting chassis 24 for power-on, so as to heat the stainless steel top cylinder 22 at the top of the heat-conducting chassis 24, so that the water in the stainless steel liner 12 and the stainless steel top cylinder 22 can be boiled. The power-on knob 214 can be rotated to cut off the power-on state between the power-connecting wire 212 below and the control wire 215. Once the control wire 215 loses the power supply to the power-connecting copper ring 216, the heat-conducting chassis 24 cannot be powered on for heating because the positive and negative poles are lost.
[0028] The working principle of the waterproof structure of the foldable kettle is described in detail below.
[0029] like Figure 1-5As shown, a solid sealing ring 151 is provided between the plastic kettle shell 11 and the inner ring of the stainless steel inner liner 12, the bottom extended inner ring 13 and the inner liner extended ring 14 to improve the waterproof effect, and three annular sealing ribs 152 are added to the outer wall of the solid sealing ring 151, so that the inner liner extended ring 14 can achieve interference fit with the inner ring of the inner ring 13 at the bottom of the inner ring of the plastic kettle shell 11 by using the annular sealing ribs 152 on the outer wall of the solid sealing ring 151, thereby further improving the plastic kettle shell 11 and the stainless steel inner liner 12. The waterproof effect between the steel liner 12 prevents water leakage. At the same time, when pouring water, the plastic top cover 41 on the top uses the stainless steel bottom plate 42 to clamp the uppermost part of the inner circle of the stainless steel liner 12, and cooperates with the extrusion between the sealing rubber ring 43 on the outer wall of the stainless steel bottom plate 42 and the inner circle of the stainless steel liner 12, so as to realize the cover of the whole pot cover mechanism 4 firmly. At the same time, the water outlet groove 44 opened on the right side of the sealing rubber ring 43 is used, so that when pouring water, the stainless steel bottom plate 42 and the sealing rubber ring 43 do not need to be opened, and the water source can only pass through the water outlet groove 44 The water is poured out from the spout structure of the kettle body mechanism 1, and the sealing rubber ring 43 is squeezed and sealed with the inner ring of the stainless steel liner 12 to prevent the water in the kettle from leaking out from the side of the stainless steel bottom plate 42 when pouring. When boiling water is needed, the power cord is inserted into the built-in power supply socket 211 and penetrates to the rear side of the plastic bottom shell 21 to turn on the power, and the copper ring 213 at the output end of the power-on wire 212 and the control wire 215 at the output end of the other power-on wire 212 and the copper ring 213 are used to connect the power supply to the power supply. 16, thereby connecting with the bottom interface of the heat-conducting chassis 24 and energizing, so as to heat the stainless steel top cylinder 22 on the top of the heat-conducting chassis 24, so that the water in the stainless steel inner tank 12 and the stainless steel top cylinder 22 can be boiled, and the power-on state between the lower power-on wire 212 and the control wire 215 can be cut off by rotating the power-on knob 214. Once the control wire 215 loses the power supply of the docking copper ring 216, the heat-conducting chassis 24 cannot be powered on for heating because of the loss of positive and negative power supply.
[0030] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
