Description

Technical Field

[0001] This invention belongs to the field of tableware equipment technology, specifically relating to an electric kettle and its boiling point identification method. Background Technology

[0002] Currently, brewing yerba mate typically requires four items: a kettle, a cup, a strainer, and a straw. The process usually involves first dividing the cup in half with the strainer, placing the yerba mate in one half and leaving the other half empty for water. The kettle stores hot water, which is then poured into the empty half of the cup. After brewing, the tea is drunk through a straw. Because these four items are usually separate and cannot be assembled, carrying them when out and about is inconvenient. The strainer and straw are small, making it easy to forget or not quickly find the straw. Furthermore, the process of filtering the tea with the strainer and then drinking it through the straw is cumbersome and provides a poor user experience. Summary of the Invention

Additionally, in the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0026] Example 1: like Figure 1-4 As shown, this embodiment provides an electric kettle, including a kettle body 100, a kettle lid 200, a cup 300, and a straw spoon 400; the kettle body 100 has an opening 110; the kettle lid 200 is installed in the opening 110, and the kettle lid 200 is used to close the opening 110, or to allow fluid in the kettle body 100 to flow out through the kettle lid 200; the cup 300 is detachably connected to the outer periphery of the opening 110; the straw spoon 400 is detachably connected to the kettle body 100, and the straw spoon 400 includes a filter part 410 and a straw part 420 that are interconnected, the filter part 410 is used to filter fluid, and the straw part 420 is used to suck up the filtered fluid.

[0027] In this embodiment, the kettle body 100, lid 200, cup 300, and straw spoon 400 constitute the overall structure of the electric kettle. The cup 300 is detachably connected to the outer periphery of the opening 110, and the straw spoon 400 is detachably connected to the kettle body 100. That is, when the cup 300 and straw spoon 400 are needed, they can be detached from the kettle body 100; when not in use, they can be reattached to the kettle body 100. This greatly facilitates the use and portability of the electric kettle. Figure 5 As shown, taking the brewing of yerba mate as an example, the fluid in this embodiment is water. The cup 300 is removed from the opening 110 of the pot body 100, forming a tea brewing container. Yerba mate tea leaves are placed in the cup 300. The pot body 100 is used to boil water, and the water in the pot body 100 can be poured into the cup 300 through the lid 200. The straw spoon 400 can filter the tea leaves while brewing the yerba mate. Figure 6 As shown, the filter 410 can push the yerba mate tea leaves in the cup 300 to one side, and the brewed tea enters the filter 410. The user can then drink the tea through the straw 420. The tea that enters the filter 410 can be enjoyed by the user through the straw 420. The filter 410 of the straw spoon 400 effectively prevents tea leaves from entering the straw 420 and causing blockage, greatly facilitating the user's tea brewing and improving the user experience.

[0028] like Figure 7 and 8 As shown, the filter section 410 includes a first filter surface 411 and a second filter surface 412; the first filter surface 411 and the second filter surface 412 enclose to form a filter section 410 with a filter space 413, the straw section 420 is connected to the filter space 413, and both the first filter surface 411 and the second filter surface 412 are provided with a plurality of filter holes 414.

[0029] In this embodiment, both the first filter surface 411 and the second filter surface 412 are spoon-shaped. The first filter surface 411 and the second filter surface 412 enclose a filter section 410 with a filter space 413. When brewing tea using a straw spoon 400, the first filter surface 411 faces the tea leaves, pushing the tea leaves to one side of the cup 300. The side of the second filter surface 412 contains tea water without tea leaves. The brewed tea water can enter the filter space 413 through either the first filter surface 411 or the second filter surface 412 and be enjoyed by the user through the straw part 420. The first filter surface 411 and The second filter surface 412 is provided with filter holes 414. The first filter surface 411 usually faces the tea leaves. The tea leaves may block the filter holes 414 on the first filter surface 411. However, due to the blocking effect of the first filter surface 411, the second filter surface 412 will not come into contact with the tea leaves. In other words, the tea leaves will not block the filter holes 414 on the second filter surface 412. The brewed tea can enter the filter space 413 through the filter holes 414 on the second filter surface 412, ensuring the water intake of the filter space 413 and ensuring that the user can enjoy the tea through the straw part 420.

[0030] like Figure 7 and 8 As shown, the straw section 420 includes a connecting section 421 and a mouthpiece section 422; one end of the connecting section 421 is connected to the filter section 410, and the other end of the connecting section 421 is connected to the mouthpiece section 422; the mouthpiece section 422 and the filter section 410 are bent away from the connecting section 421, and the bending directions of the mouthpiece section 422 and the filter section 410 are opposite; the cross-section of the mouthpiece section 422 is elliptical, and the mouthpiece section 422 has a first end 4221 and a second end 4222. From the first end 4221 to the second end 4222, the major radius of the elliptical cross-section of the mouthpiece section 422 remains unchanged, while the minor radius gradually decreases.

[0031] In this embodiment, the connecting section 421 is a straight pipe section with a circular, elliptical, or square cross-section; the spout section 422 is a bent pipe section with a circular, elliptical, or square cross-section, preferably elliptical; the spout section 422 and the filter section 410 are bent away from the connecting section 421, and the bending directions of the spout section 422 and the filter section 410 are opposite. When brewing tea, the filter section 410 is bent relative to the connecting section 421, and the filter section 410 pushes the tea leaves to one side of the cup 300 for easy brewing. The spout section 422 is bent relative to the connecting section 421, and the bending direction is opposite to that of the filter section 410. The spout section 422 faces the user's mouth, which greatly facilitates the user's enjoyment of tea and improves the user experience. The ellipse section 422, from the first end 4221 to the second end 4222, has a constant major radius and a gradually decreasing minor radius. In other words, the area of ​​the ellipse section 422 gradually decreases from the first end 4221 to the second end 4222, and the diameter of the mouth section gradually decreases. On the one hand, when the user sucks the tea, the flow rate of the tea in the mouth section can be increased, ensuring that the user can fully enjoy the tea and improving the user experience. On the other hand, the shape of the mouthpiece end fits the user's mouth better, improving the user experience.

[0032] like Figure 3 and 8 As shown in the figure, as one embodiment, the straw spoon 400 is provided with a hook 430, the pot body 100 is provided with a hanging piece, and a hanging groove 1141 is formed between the hanging piece 114 and the pot body 100. The straw spoon is detachably connected to the pot body 100 by inserting the hook 430 into the hanging groove 1141.

[0033] like Figure 4 As shown, the kettle body 100 includes a kettle body 112 and a heating module 113 disposed at the bottom of the kettle body 112; the heating module 113 includes a bottom cover 1131, a heating element 1132, a control element 1134, and a temperature measuring element 1135; the heating element 1132, the control element 1134, and the temperature measuring element 1135 are integrated in the bottom cover 1131, and the heating element 1132 and the temperature measuring element 1135 are both electrically connected to the control element 1134. The heating element 1132 is used to heat the water in the kettle body 112, and the temperature measuring element 1135 is used to measure the temperature of the water in the kettle body 112.

[0034] In this embodiment, the heating element 1132 is a heating plate, the control element 1134 is a circuit board, and the temperature sensing element 1135 is an NTC temperature probe. The heating element 1132, control element 1134, and temperature sensing element 1135 are integrated into the bottom cover 1131. The heating element 1132 heats the water in the kettle body 112, and when the temperature sensing element 1135 detects that the water in the kettle body 112 has reached the required temperature, the temperature sensing element 1135 sends a signal to the control element 1134. After receiving the signal, the control element 1134 controls the heating element 1132 to stop heating. In this way, intelligent control of the electric kettle can be achieved. As one embodiment, the heating module 113 may also include a thermostat, which can provide power-off protection for the electric kettle.

[0035] like Figure 9-13 As shown, the kettle lid 200 includes a main body 210, a pressure relief assembly 220, and a pressing assembly 230; the main body 210 has a water inlet end 211 and a water outlet end 212 that are interconnected; the pressure relief assembly 220 includes a pressure relief box 221, a steam exhaust channel 222, and a breathable membrane 223; the bottom of the pressure relief box 221 is provided with a steam inlet hole 2211, and the breathable membrane 223 is disposed inside the pressure relief box 221 and covers the steam inlet hole 2211; One end of the venting channel 222 is connected to the pressure relief box 221 and communicates with the interior of the pressure relief box 221. The other end passes through the main body 210 and communicates with the outside. The pressing component 230 is disposed in the main body 210 and connected to the venting channel 222. The pressing component 230 can drive the venting channel 222 to move so that the upper side of the pressure relief box 221 opens or closes the water inlet end 211.

[0036] In this embodiment, when the electric kettle is boiling water, the steam exhaust channel 222 is moved by the pressing component 230, so that the upper side of the pressure relief box 221 closes the water inlet end 211 of the main body 210. At this time, only the steam exhaust channel 222 is connected to the outside of the kettle body 100. Since the bottom of the pressure relief box 221 is provided with a steam inlet hole 2211, and the vent membrane 223 is provided inside the pressure relief box 221 and covers the steam inlet hole 2211, the vent membrane 223 can be fixed inside the pressure relief box 221 by ultrasonic hot-melt welding. The steam generated inside the kettle body 100 can enter the interior of the pressure relief box 221 through the vent membrane 223, and then enter the steam exhaust channel 222 from the interior of the pressure relief box 221 to the outside of the electric kettle. In this way, it can be ensured that when the electric kettle is heating water, the steam can be smoothly discharged through the vent membrane 223, while the water cannot pass through the vent membrane 223, avoiding water leakage from the kettle body 100. Excessive steam inside ensures pressure balance when the electric kettle heats water, preventing safety accidents. Furthermore, since the interior of the electric kettle is only connected to the outside through the steam inlet 2211, the breathable membrane 223 covers the steam inlet 2211. The breathable membrane 223 effectively prevents heat loss from the water inside the electric kettle, improving the kettle's heat preservation effect. When water needs to be poured from the electric kettle, the steam venting channel 222 is moved by pressing component 230, which causes the upper side of the pressure relief box 221 to open the water inlet 211 of the main body 210. Water in the kettle body 100 enters the interior of the main body 210 through the water inlet 211 and is then poured out through the water outlet 212. Due to the presence of the breathable membrane 223, the pressure relief component 220 prevents water from entering the pressure relief box 221 through the steam inlet 2211. Thus, water in the kettle body 112 can only flow from the water inlet 211 to the water outlet 212 and be poured out from the water outlet 212. This prevents water in the kettle body 112 from being discharged from the steam venting channel 222 of the lid 200 when pouring water, ensuring that the lid 200 can pour water smoothly and improving the user experience.

[0037] As one embodiment, the breathable membrane 223 is made of expanded polytetrafluoroethylene (e-PTFE), specifically an expanded polytetrafluoroethylene film. Its micropores can block various particles while allowing air to pass through. In other words, the breathable membrane 223 only allows steam to pass through, while water cannot, thus having good waterproof performance. When the electric kettle heats water, steam can pass through the breathable membrane 223, while the water inside the electric kettle cannot pass through, effectively preventing the electric kettle from leaking. Furthermore, the material of the breathable membrane 223 has good chemical inertness and thermal stability, making it suitable for use in electric kettles.

[0038] like Figure 17-20As shown, the pressure relief box 221 includes a base 2212 and a top cover 2213; the top cover 2213 is fixedly connected to the top of the base 2212, and a pressure relief cavity 2214 is formed between the base 2212 and the top cover 2213; the steam exhaust channel 222 is disposed above the top cover 2213 and is connected to the pressure relief cavity 2214; the steam inlet 2211 is disposed on the base 2212 and is connected to the pressure relief cavity 2214; the breathable membrane 223 is disposed inside the base 2212; wherein, the pressing component 230 can drive the steam exhaust channel 222 to move, so that the top cover 2213 opens or closes the water inlet end 211.

[0039] In this embodiment, a pressure relief chamber 2214 is formed between the upper cover 2213 and the base 2212. A steam exhaust channel 222 is provided on the upper cover 2213 and is connected to the pressure relief chamber 2214. The base 2212 is provided with a steam inlet 2211, and a breathable membrane 223 is provided on the base 2212. At this time, the interior of the kettle body 100 is only connected to the outside through the steam inlet 2211. The breathable membrane 223 covers the breathable hole. When the electric kettle boils water, the steam generated inside the kettle body 100 can enter the pressure relief chamber 2214 through the breathable hole on the base 2212 and the breathable membrane 223, and then enter the steam exhaust channel 222 from the pressure relief chamber 2214 to be discharged to the outside, thereby reducing the gas pressure generated when the electric kettle boils water. As one embodiment, a sealing ring 240 is provided between the upper cover 2213 and the base 2212 to ensure the watertightness of the connection between the upper cover 2213 and the base 2212.

[0040] like Figure 17-20As shown, the pressure relief assembly 220 further includes a pressure relief valve 224 and a pressure relief spring 225; the base 2212 is provided with a pressure relief hole 2212a, the pressure relief valve 224 is inserted into the pressure relief hole 2212a, and the pressure relief valve 224 is movably connected to the pressure relief hole 2212a; one end of the pressure relief spring 225 abuts against the pressure relief valve 224, and the other end of the pressure relief spring 225 abuts against the exhaust passage 222; the pressure relief valve 224 includes a plug-in portion 2241 and a fixing portion 2242 disposed around the plug-in portion 2241; a connecting groove 2243 is formed between the plug-in portion 2241 and the fixing portion 2242, and the pressure relief hole 2212a is provided with a protrusion 2243 adapted to the connecting groove 2243 in the direction of the pressure relief chamber 2214. 12b, the protrusion 2212b is inserted into the connecting groove 2243; the fixing part 2242 is inserted into the pressure relief hole 2212a, and the fixing part 2242 is movably connected to the pressure relief hole 2212a; the insertion part 2241 is provided with a fixing groove 2241a, and the exhaust passage 222 is provided with a stepped groove 2221; one end of the pressure relief spring 225 is located in the fixing groove 2241a, and the other end of the pressure relief spring 225 is located in the stepped groove 2221; the base 2212 is provided with a guide ring 2212c, the guide ring 2212c extends toward the pressure relief chamber 2214, the pressure relief valve 224 is located in the guide ring 2212c, and the fixing part 2242 of the pressure relief valve 224 is movably connected to the guide ring 2212c.

[0041] It should be noted that when the electric kettle heats water, if the amount of steam produced is greater than the permeability of the breathable membrane 223, or if the breathable membrane 223 is damaged and cannot breathe, the steam will accumulate in large quantities inside the kettle body 100, resulting in excessively high air pressure. In this embodiment, the pressure relief chamber 2214 is connected to the interior of the kettle body 112 through the pressure relief hole 2212a. The pressure relief valve 224 is inserted into the pressure relief hole 2212a on the bottom cover 1131, and the pressure relief valve 224 is movably connected to the pressure relief hole 2212a, that is, the pressure relief valve 224 can move up and down within the pressure relief hole 2212a. One end of the pressure relief spring 225 abuts against the pressure relief valve 224, and the other end of the pressure relief spring 225 abuts against the steam exhaust channel 222. When the steam pressure inside the kettle body 112 is too high, it pushes up the pressure relief valve 224. The pressure relief valve 224 moves towards the pressure relief chamber 22141 within the pressure relief hole 2212a, and the pressure relief spring 225 is compressed, so that the interior of the kettle body 100 is connected to the pressure relief chamber 2214 through the pressure relief hole 2212a. At this time, the kettle body 100... The steam inside can enter the pressure relief chamber 2214 through the pressure relief hole 2212a, and then be discharged to the outside of the electric kettle through the steam exhaust channel 222. In this way, the pressure balance inside the electric kettle can be further ensured. When the pressure inside the kettle body 100 is restored to balance, due to the elasticity of the pressure relief spring 225, the pressure relief valve 224 moves toward the pressure relief hole 2212a under the elastic force of the pressure relief spring 225, so that the pressure relief valve 224 is re-inserted into the pressure relief hole 2212a, preventing the water in the kettle body 112 from flowing into the pressure relief chamber 2214 through the pressure relief hole 2212a.

[0042] Furthermore, a connecting groove 2243 is formed between the insertion part 2241 and the fixing part 2242. A protrusion 2212b, adapted to the connecting groove 2243, is provided in the pressure relief hole 2212a facing the pressure relief chamber 2214. A first inclined surface is provided in the connecting groove 2243, and a second inclined surface is provided in the protrusion 2212b, adapted to the first inclined surface. The protrusion 2212b is inserted into the connecting groove 2243, with the first and second inclined surfaces abutting against each other. The fixing part 2242 is inserted into the pressure relief hole 2212a, and is movably connected to the pressure relief hole 2212a. When the air pressure inside the kettle body 100 is too high, the fixing part 2242 is lifted, and the fixing part 2242 moves within the pressure relief hole 2212a towards the pressure relief chamber 2214, thereby allowing the kettle body 100 to... The internal structure of the pressure relief valve 224 is connected to the pressure relief chamber 2214 via a pressure relief hole 2212a to relieve pressure on the electric kettle. Furthermore, the protrusion 2212b acts as a limiter for the pressure relief valve 224, preventing it from falling from the pressure relief hole 2212a into the kettle body 100. One end of the pressure relief spring 225 is located within and abuts against the fixing groove 2241a, while the other end is located within and abuts against the stepped groove 2221. The fixing groove 2241a and the stepped groove 2221 provide a fixing and guiding function for the pressure relief spring 225, preventing it from falling off when the pressure relief valve 224 moves, thus affecting the pressure relief effect. The pressure relief valve 224 is located inside the guide ring 2212c, and the fixing part 2242 of the pressure relief valve 224 is movably connected to the guide ring 2212c. When the air pressure inside the kettle body 112 is too high, it pushes up the pressure relief valve 224. The pressure relief valve 224 can move along the guide ring 2212c toward the pressure relief chamber 2214. The guide ring 2212c guides the pressure relief valve 224. When the pressure relief valve 224 moves toward the pressure relief chamber 2214, the guide ring 2212c limits the lateral movement of the pressure relief valve 224, restricting the pressure relief valve 224 to move only up and down, but not left and right. This prevents the pressure relief valve 224 from shifting, which would prevent the pressure relief valve 224 from being reinserted into the pressure relief hole 2212a after the air pressure inside the kettle body 100 returns to equilibrium, thus affecting the pressure relief effect of the electric kettle.

[0043] like Figure 11-13As shown, the main body 210 includes a sealing seat 213, a support frame 214, a fixing ring 215, and a water outlet cover 216; the support frame 214 and the fixing ring 215 are coaxially arranged, and the support frame 214 is located inside the fixing ring 215; the sealing seat 213 is provided with a slot 2131, and the bottoms of the support frame 214 and the fixing ring 215 are engaged in the slot 2131; the sealing seat 213 is provided with a water inlet. The water inlet is the water inlet end 211 of the main body 210; the water outlet cover 216 is installed on the outer periphery of the upper part of the support frame 214 and the fixing ring 215, and the water outlet cover 216 is provided with a water outlet, which is the water outlet end 212 of the kettle lid 200; wherein, the support frame 214, the fixing ring 215 and the water outlet cover 216 form a water outlet channel, and the water inlet and the water outlet can be connected through the water outlet channel.

[0044] In this embodiment, the membrane, support frame 214, fixing ring 215, and water outlet cap 216 enclose a water outlet channel. The water outlet of the water outlet cap 216 and the water inlet of the sealing seat 213 are connected through the water outlet channel. When water needs to be poured out, the pressing component 230 drives the steam exhaust channel 222 to move, so that the upper side of the pressure relief box 221 opens the water inlet end 211, that is, opens the water inlet of the sealing seat 213. The water in the kettle body 100 can then enter the water outlet channel through the water inlet and flow from the water outlet channel to the water outlet, realizing the pouring of water from the electric kettle. The sealing seat 213 is preferably made of rubber. The bottom of the sealing seat 213 is provided with an abutment part 2132, which is triangular. When the pressure relief box 221 closes the water outlet end 212 of the main body 210, the abutment part 2132 fits tightly with the upper end surface of the pressure relief box 221, preventing water from seeping out from between the pressure relief box 221 and the sealing seat 213. A sealing ring 240 is provided between the support frame 214 and the fixing ring 215, as well as between the fixing ring 215 and the water outlet cover 216, to ensure the water tightness of the body 210 of the lid 200.

[0045] like Figure 12 , 14As shown in Figure 15, in one embodiment, an annular groove 2131a is provided in the slot 2131, and an annular protrusion 2151 adapted to the annular groove 2131a is provided on the outer periphery of the fixing ring 215. The annular protrusion 2151 is engaged in the annular groove 2131a. A snap-fit ​​block 2143 is provided on the outer periphery of the support frame 214, and a snap-fit ​​groove 2152 adapted to the snap-fit ​​block 2143 is provided on the inner periphery of the fixing ring 215. The snap-fit ​​block 2143 is engaged in the snap-fit ​​groove 2152. First, the bottom of the support frame 214 and the fixing ring 215 are engaged in the slot 2131, and then the annular protrusion 2151 is engaged in the annular groove 2131a, ensuring the connection and fixation between the support frame 214, the fixing ring 215, and the sealing seat 213, and ensuring the integrity of the main body 210.

[0046] like Figure 11 , 13 As shown in Figure 16, a guide seat 2141 is formed inside the support frame 214, and the guide seat 2141 is provided with a guide hole 2141a. The steam exhaust channel 222 is movably connected to the guide hole 2141a. A mounting base 2142 is formed on the top of the support frame 214. One end of the steam exhaust channel 222 away from the pressure relief box 221 passes through the guide hole 2141a and extends into the mounting base 2142. The water outlet cover 216 includes a first vertical portion connected in sequence. 2161, connecting part 2162, and second vertical part 2163; the first vertical part 2161 and the second vertical part 2163 are arranged opposite to each other; the water outlet is provided on the first vertical part 2161, the first vertical part 2161 abuts against the fixing ring 215, the second vertical part 2163 is fixedly connected to the inner side of the mounting base 2142, the pressing component 230 is installed in the second vertical part 2163 and connected to the exhaust channel 222.

[0047] In this embodiment, a guide seat 2141 is formed inside the support frame 214, and there is a gap between the guide seat 2141 and the support frame 214. This gap is part of the water outlet channel. A mounting seat 2142 is formed above the support frame 214, and there is a gap between the mounting seat 2142 and the fixing ring 215. This gap is also part of the water outlet channel. When the electric kettle is filled, the water in the kettle body 100 enters the gap between the guide seat 2141 and the support frame 214 through the water inlet end 211 of the sealing seat 213, then enters the gap between the mounting seat 2142 and the fixing ring 215, and finally flows out through the water outlet on the water outlet cover 216. The guide seat 2141 is provided with a guide hole 2141a, and the exhaust passage 222 is movably connected in the guide hole 2141a. The exhaust passage 222 and the guide seat 2141 are coaxially arranged. The pressing component 230 is installed in the mounting base 2142. The pressing component 230 drives the exhaust passage 222 to move up and down along the guide hole 2141a, thereby realizing the sealing or opening of the pressure relief box 221 to the water inlet. The first vertical portion 2161, the connecting portion 2162, and the second vertical portion 2163 are connected. The first vertical portion 2161 and the second vertical portion 2163 are arranged opposite to each other, so that the cross-section of the water outlet cover 216 is U-shaped. There is a gap between the first vertical surface and the mounting base 2142, which is also part of the water outlet channel. Thus, the gap between the guide seat 2141 and the support frame 214, the gap between the mounting base 2142 and the fixing ring 215, and the gap between the first vertical portion 2161 and the mounting base 2142 form the water outlet channel. The water inlet of the sealing seat 213 communicates with the water outlet on the first vertical portion 2161 through the gap between the guide seat 2141 and the support frame 214, the gap between the mounting base 2142 and the fixing ring 215, and the gap between the first vertical surface and the mounting base 2142.

[0048] like Figure 11 and 13 As shown in one embodiment, the first vertical portion 2161 abuts against the fixing ring 215. A sealing ring 240 can be provided between the first vertical portion 2161 and the fixing ring 215 to ensure water tightness between them. The second vertical portion 2163 and the inner side of the mounting base 2142 can be fixedly connected by a snap-fit ​​mechanism. The first vertical portion 2161 is provided with a vent 2161a, which is connected to the water outlet channel and is positioned opposite to the water outlet. When pouring water from the electric kettle, the vent 2161a can release steam from the water outlet channel, ensuring smooth pouring.

[0049] like Figure 11 , 13As shown in Figure 16, the pressing assembly 230 includes a pressing button 231, an anti-rotation wheel 232, and a return spring 233; the second vertical portion 2163 is provided with a ratchet structure, the ratchet structure including a plurality of ratchet low positions 2163a and ratchet high positions 2163b spaced apart, and a return tooth 2163c is provided between the ratchet low positions 2163a and the ratchet high positions 2163b; the bottom of the pressing button 231 is provided with a protruding tooth 2311, the anti-rotation wheel 232 is located below the pressing button 231, and the protruding tooth 2311 abuts against the anti-rotation wheel 232; the periphery of the anti-rotation wheel 232 is provided with anti-rotation teeth 2321, the anti-rotation teeth 2321 engaging. The ratchet is located in the lower position 2163a or the higher position 2163b; the return spring 233 is sleeved on the outer periphery of the exhaust channel 222, one end of the return spring 233 abuts against the bottom of the guide seat 2141, and the other end of the return spring 233 abuts against the anti-rotation wheel 232; wherein, when the anti-rotation tooth 2321 of the anti-rotation wheel 232 is engaged in the lower position 2163a of the ratchet, the pressure relief box 221 closes the water inlet end 211 of the main body 210; when the anti-rotation tooth 2321 of the anti-rotation wheel 232 is engaged in the higher position 2163b of the ratchet, the pressure relief box 221 opens the water inlet end 211 of the main body 210.

[0050] In this embodiment, the ratchet structure includes several ratchet lower positions 2163a and ratchet higher positions 2163b spaced apart. A reset tooth 2163c is provided between the ratchet lower positions 2163a and the ratchet higher positions 2163b. The end faces of the ratchet higher positions 2163b and the reset tooth 2163c are inclined surfaces. A step is formed between the ratchet higher positions 2163b and the reset tooth 2163c. The anti-rotation tooth 2321 of the anti-rotation wheel 232 has an inclined surface that is adapted to the ratchet higher positions 2163b and the reset tooth 2163c. When the electric kettle is not in use or when boiling water, the anti-rotation tooth 2321 of the anti-rotation wheel 232 engages in the ratchet low position 2163a, and the pressure relief box 221 seals the water inlet 211 of the main body 210. When it is necessary to use the electric kettle to pour water, pressing the button 231 causes the button 231 to push the anti-rotation tooth 2321 downward through the protrusion 2311. The anti-rotation tooth 2321 drives the steam exhaust channel 222 to move downward, compressing the return spring 233. This allows the pressure relief box 221 to open the water inlet end 211 of the kettle lid 200 body 210 until the anti-rotation tooth 2321 of the anti-rotation wheel 232 engages with the ratchet high position 2163b. Because the anti-rotation tooth 2321 has an inclined surface adapted to the ratchet high position 2163b, the anti-rotation wheel 232 rotates until the anti-rotation tooth 2321 engages between the ratchet high position 2163b and the reset tooth 2163c, forming a step. The water inlet end 211 then connects with the kettle body 100. The internal connection is open, and water can be poured out at this time. After the water is poured out, press the button 231. The button 231 drives the anti-rotation wheel 232 to move downward until the anti-rotation tooth 2321 is engaged with the reset tooth 2163c. Since the anti-rotation tooth 2321 has an inclined surface that matches the reset tooth 2163c, release the button 231. Under the elastic force of the reset spring 233, the anti-rotation wheel 232 is pushed upward. The anti-rotation tooth 2321 moves on the reset tooth 2163c, and the anti-rotation wheel 232 rotates until the anti-rotation tooth 2321 falls into the ratchet low position 2163a. ​​At this time, the pressure relief box 221 closes the water inlet end 211 of the main body 210.

[0051] like Figure 3 and 4 As shown, a fixing ring 111 is provided on the outer periphery of the opening 110, and the cup 300 is detachably connected to the fixing ring 111; a steam venting space 310 is formed between the cup 300 and the lid 200; wherein, the fixing ring 111 and / or the cup 300 are provided with a steam venting groove 320, and the steam venting groove 320 connects the steam venting space 310 and the outside of the electric kettle.

[0052] In this embodiment, the upper part of the kettle body 100 is bent towards the center of the kettle body 100 to form an opening 110. The kettle lid 200 is installed inside the opening 110, and a retaining ring 111 is sleeved on the outer periphery of the opening 110. The cup 300 is detachably connected to the outer side of the retaining ring 111. Specifically, the kettle lid 200 can be threaded into the opening 110 to facilitate the connection or disassembly of the kettle lid 200 and the kettle body 100. The steam venting channel 222 connects to the internal space of the kettle body 100. When the electric kettle boils water, the water inside the kettle body 100 is heated to generate steam, which can be discharged through the steam venting channel 222 to prevent the kettle body 100 from being scalded. If the internal air pressure is too high, the steam discharged from the steam venting channel 222 will enter the steam venting space 310 between the cup 300 and the lid 200. Since the fixing ring 111 and / or the cup 300 are provided with a steam venting groove 320, which connects the steam venting space 310 and the outside of the electric kettle, the steam in the steam venting space 310 can be discharged to the outside of the electric kettle along the steam venting groove 320, avoiding the steam from being trapped in the steam venting space 310 between the cup 300 and the lid 200. In this way, when the electric kettle finishes boiling water, the user can open the cup 300, which effectively avoids the steam from scalding the user and ensures the user's safety when using the electric kettle.

[0053] like Figure 3 and 4 As shown, the inner side of the cup 300 is provided with a first connecting structure 330, and the outer side of the fixing ring 111 is provided with a second connecting structure 1111. The first connecting structure 330 of the cup 300 and the second connecting structure 1111 of the fixing ring 111 cooperate to allow the cup 300 to be detachably connected to the fixing ring 111. The inner side of the cup 300 is provided with a steam venting groove 320, which penetrates the first connecting structure 330. And / or, the outer side of the fixing ring 111 is provided with a steam venting groove 320, which penetrates the second connecting structure 1111.

[0054] In this embodiment, the first connecting structure 330 of the cup 300 and the second connecting structure 1111 of the fixing ring 111 cooperate to make the cup 300 and the fixing ring 111 detachably connected. When the electric kettle needs to boil water or the cup 300 is not in use, the cup 300 can be fixed to the second connecting structure 1111 of the fixing ring 111. When the cup 300 needs to be used alone for drinking water or making tea, it can be removed from the first connecting structure 330. In this embodiment, the first connecting structure 330 is an internal thread and the second connecting structure 1111 is an external thread. The detachable connection between the cup 300 and the fixing ring 111 is achieved through the cooperation of the internal and external threads. Of course, the first connecting structure 330 and the second connecting structure 1111 can also be a snap-fit ​​groove 2131 or a magnetic attraction structure, as long as it can achieve the detachable connection between the cup 300 and the fixing ring 111, and there is no limitation here.

[0055] Furthermore, the inner side of the cup 300 and the outer side of the fixing ring 111 can both be provided with venting grooves 320, or the inner side of the cup 300 can be provided with venting grooves 320 alone, or the outer side of the fixing ring 111 can be provided with venting grooves 320 alone. In this embodiment, the outer side of the fixing ring 215 is provided with venting grooves 320 alone. In this embodiment, when the cup 300 is fixed on the outer periphery of the fixing ring 215, the first connecting structure 330 and the second connecting structure 1111 fit tightly together, resulting in the sealing of the venting space 310. The venting groove 320 passes through the first connecting structure 330 or the second connecting structure 1111, allowing the sealed venting space 310 to communicate with the outside of the electric kettle. In this way, the steam that is discharged from the kettle body 100 to the venting space 310 through the venting channel 222 can be discharged to the outside of the electric kettle along the venting groove 320, avoiding the retention of steam in the venting space 310 and the potential safety hazard to the user.

[0056] like Figure 4 As shown in the illustration, in one embodiment, the cup 300 includes an inner liner 340 and an outer liner 350, which are fixedly connected. A vacuum layer 360 is formed between the inner liner 340 and the outer liner 350. The first connecting structure 330 is disposed on the inner liner 340. The inner liner 340 and the outer liner 350 can be fixedly connected by welding, forming a vacuum layer 360 between them. When using the cup 300 to drink water or make tea, the user holds the outer liner 350. Due to the presence of the vacuum layer 360, it provides good heat insulation, preventing the hot water inside the cup 300 from scalding the user.

[0057] like Figure 1-3As shown, the electric kettle also includes a handle 500, which includes a first mounting block 510, a second mounting block 520, a first handle 530, and a second handle 540. The first mounting block 510 and the second mounting block 520 are both fixedly connected to the kettle body 112, and are arranged opposite to each other. One end of the first handle 530 is rotatably connected to the first mounting block 510, and the other end is rotatably connected to the second mounting block 520. One end of the second handle 540 is rotatably connected to the first mounting block 510, and the other end is rotatably connected to the second mounting block 520. The first handle 530 includes a first lifting handle 531 and a first rotating shaft 532 disposed at both ends of the first lifting handle 531. The first rotating shafts 532 at both ends are rotatably connected to the first mounting block 510 and the second mounting block 520, respectively; the second handle 540 includes a second handle 541 and second rotating shafts 542 disposed at both ends of the second handle 541, and the second rotating shafts 542 at both ends of the second handle 541 are rotatably connected to the first mounting block 510 and the second mounting block 520, respectively; wherein, when the handle 500 is in the first state, the first handle 530 and the second handle 540 rotate in opposite directions, and the first handle 530 and the second handle 540 respectively abut against the body 112; when the handle 500 is in the second state, the first handle 530 and the second handle 540 rotate towards each other, and the first handle 530 and the second handle 540 abut against each other.

[0058] In this embodiment, the first mounting block 510 and the second mounting block 520 can be fixedly connected to the pot body 100 by welding or gluing. The first mounting block 510 is fixed to the upper part of the pot body 100, and the second mounting block 520 is fixed to the lower part of the pot body 100. The first mounting block 510 and the second mounting block 520 are arranged opposite to each other. The two ends of the first handle 530 and the second handle 540 are respectively rotatably connected to the first mounting block 510 and the second mounting block 520. The handle 500 has a first state and a second state. In the first state, after the electric kettle is finished using it, it needs to be stored away. At this time, the first handle 530 and the second handle 540 rotate in opposite directions, that is, the first handle 530 and the second handle 540 rotate in different directions closer to the kettle body 100, so that the first handle 530 and the second handle 540 are close to the kettle body 100, preventing the first handle 530 and the second handle 540 from protruding from the kettle body 100. When storing the electric kettle, the first handle 530 and the second handle 540 are prevented from occupying too much storage space, which greatly facilitates the storage of the electric kettle. The second state is the state when the electric kettle needs to be used. When the electric kettle needs to be used, the first handle 530 and the second handle 540 are rotated in opposite directions away from the kettle body 100. The first handle 530 and the second handle 540 come into contact with each other, that is, the first handle 530 and the second handle 540 can be joined together. The user can lift the electric kettle or pour water by holding the first handle 530 and the second handle 540, which greatly facilitates the user's use of the electric kettle.

[0059] Furthermore, by rotating the first mounting block 510 and the second mounting block 520 via the first rotating shaft 532 located at both ends of the first handle 531, the first handle 530 is rotatably connected, facilitating rotation of the first handle 530 toward or away from the pot body 100. When assembling the first handle 530, the first rotating shaft 532 can be first installed onto the first mounting block 510 and the second mounting block 520, and then the first handle 531 can be installed onto the two first rotating shafts 532 to complete the assembly of the first handle 530. This greatly facilitates the installation of the first handle 530 onto the pot body 112. Similarly, by rotating the first mounting block 510 and the second mounting block 520 via the second rotating shaft 542 located at both ends of the second handle 541, the second handle 540 is rotatably connected, facilitating rotation of the second handle 540 toward or away from the pot body 100. When assembling the second handle 540, the second rotating shaft 542 can be first installed onto the first mounting block 510 and the second mounting block 520, and then the second handle 541 can be installed onto the two second rotating shafts 542 to complete the assembly of the second handle 540, greatly facilitating the installation of the second handle 540 onto the kettle body 100. The first handle 500 and the second handle 500 are made of plastic or rubber, while the first rotating shaft 532 and the second rotating shaft 542 are made of stainless steel. The stainless steel first rotating shaft 532 and the second rotating shaft 542 have high strength and corrosion resistance, and will not be damaged even after long-term rotation, ensuring the service life of the first rotating shaft 532 and the second rotating shaft 542.

[0060] like Figure 1 As shown in the figure, in one embodiment, the outer surface of the kettle body 100 is cylindrical, and the first handle 530 and the second handle 540 are both arc-shaped. The shapes of the first handle 530 and the second handle 540 are adapted to the outer surface of the kettle body 100. When the electric kettle needs to be stored, the first handle 530 and the second handle 540 are rotated in opposite directions until the first handle 530 and the second handle 540 are in contact with the kettle body 100, so as to prevent the first handle 530 and the second handle 540 from protruding from the kettle body 100 and to facilitate the storage of the electric kettle.

[0061] Example 2: This embodiment improves a boiling point identification method for an electric kettle, applied to the electric kettle described in Embodiment 1. The boiling point identification method includes the following steps: S100, control the heating element 1132 to heat the water in the kettle body 112; S200 and temperature sensing element 1135 detect the temperature of the water inside the kettle body 112; S300: When the temperature sensing element 1135 detects that the water in the kettle body 112 exceeds the preset temperature, it continues to rise within a preset time. It is determined that the water in the kettle body 112 has not yet boiled, and the heating element 1132 continues to heat the water in the kettle body 112. When the temperature sensing element 1135 detects that the water in the kettle body 112 exceeds the preset temperature, the temperature remains unchanged within a preset time. It is determined that the water in the kettle body 112 has boiled, and the control element 1134 controls the heating element 1132 to stop heating.

[0062] It should be noted that when an electric kettle boils water at high altitudes, the boiling point of water is usually below 100°C due to environmental factors, making it difficult to determine whether the water has boiled. In this embodiment, the temperature sensing element 1135 monitors the water in the kettle body 112 in real time. When the temperature sensing element 1135 detects that the water in the kettle body 112 exceeds a preset temperature, it continues to rise for a preset time. For example, if the preset temperature is 60°C and the preset time is 40 seconds, the continuously rising temperature indicates that the water in the kettle body 112 has not yet boiled. The heating element 1132 continues to heat the water in the kettle body 112. When the detected temperature remains unchanged, it indicates that the water in the kettle body 112 has boiled. At this point, the control element 1134 controls the heating element 1132 to stop heating, preventing continuous heating of the water in the kettle body 112 and providing good protection for the electric kettle.
