The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0036] The lid of an electric kettle is usually made of stainless steel, which is light and low in cost. However, stainless steel contains a variety of metal elements. When the electric kettle heats water, the water vapor generated by the heated water will adhere to the lid, and the high-temperature water vapor may react chemically with the metal elements in the stainless steel (lid). At this time, the condensed water vapor falls into the kettle body, which will affect the water quality in the electric kettle, resulting in a poor taste of the water and even affecting human health. In order to solve this problem, the embodiment of the present application provides an electric kettle 100 ( Figure 1 shown).

[0037] See also Figures 1 to 3The electric kettle 100 of the embodiment of the present application includes a kettle body 10 and a kettle cover 30. The kettle body 10 is provided with a cavity 11, one end of the cavity 11 is closed, and the other end is provided with an opening 13. The kettle cover 30 is installed on the kettle body 10 and covers the opening 13. The kettle cover 30 includes a first structure 31 and a second structure 33. The first structure 31 is connected to the top of the kettle body 10, and the second structure 33 is connected to the first structure 31 and is located on the side of the first structure 31 away from the cavity 11. At least part of the first structure 31 is a silver structure.

[0038] Specifically, the electric kettle 100 is a structure for heating the substance loaded inside the electric kettle 100 by powering on. The substance loaded inside the electric kettle 100 may be, but is not limited to, liquid, solid, or a solid-liquid mixture. Among them, liquids include, but are not limited to, water, coffee, milk, and oil, etc., solid-liquid mixtures include tea (water + tea leaves), scented tea, and fruit tea, etc., and solids include coffee beans, tea leaves, and candy, etc. This application takes the example of loading water inside the electric kettle 100 for explanation, and the electric kettle 100 can be powered on to heat the water inside the electric kettle 100.

[0039] The cavity 11 of the kettle body 10 is used for water to be loaded therein. When water needs to be heated, water is loaded into the cavity 11 from the opening 13. When the electric kettle 100 is powered on, the kettle body 10 is used to transfer the heat generated by the heating element 70 of the electric kettle 100 to various positions of the water, so that the water in the cavity 11 is heated. The shape of the opening 13 of the kettle body 10 may be, but not limited to, circular, elliptical, triangular, quadrilateral or other polygonal. The volume of the cavity 11 may be, but not limited to, 0.5L, 0.8L, 1.2L, 1.5L, 1.7L, 1.8L, 2L, 3L, 3.5L or 4L, etc. When the volume of the cavity 11 is small (for example, 0.5L or 0.8L), less water can be loaded in the cavity 11. When the electric kettle 100 is powered on, the water in the cavity 11 can be quickly heated. When the volume of the cavity 11 is relatively large (for example, 2 L or 3 L), more water can be loaded in the cavity 11, and the electric kettle 100 can heat a larger amount of water at one time.

[0040] The pot cover 30 is installed on the top of the pot body 10 and covers the opening 13. The shape of the pot cover 30 can be, but is not limited to, circular, elliptical, triangular, quadrilateral or other polygonal shapes. Preferably, the shape of the pot cover 30 is the same as the shape of the opening 13, so that the pot cover 30 can cooperate well with the opening 13. The pot cover 30 covers the opening 13 of the pot body 10 to prevent dust or impurities from the outside from entering the cavity 11, thereby ensuring the cleanliness of the water in the cavity 11. When the water in the cavity 11 is heated, the pot cover 30 can also prevent high-temperature water vapor from directly escaping from the opening 13, thereby avoiding the problem of scalding the user. In addition, the pot cover 30 can also have a certain insulation effect on the hot water in the cavity 11, and the pot cover 30 can slow down the heat loss of the hot water, so that the hot water can maintain the heat for a certain period of time.

[0041] The pot cover 30 is also provided with a vent 35, which runs through the first structure 31 and the second structure 33, and the vent 35 is used to connect the cavity 11 with the outside. When the water in the cavity 11 is heated, the vent 35 is used to discharge the water vapor to the outside of the cavity 11, so as to balance the air pressure in the cavity 11 and avoid the problem of bursting due to excessive air pressure in the cavity 11. At the same time, when the kettle body 30 needs to pour water, the kettle body 30 pours water more smoothly because the vent 35 can balance the air pressure in the cavity 11. When pouring water from the kettle body 30, the problem of too fast water flow when the air pressure in the cavity 11 is too high can be avoided, and the problem of water not being able to flow out when the air pressure in the cavity 11 is too low can also be avoided. The opening shape of the vent 35 can be, but is not limited to, circular, elliptical, triangular, quadrilateral or other polygonal shapes.

[0042] In one embodiment, the material of the inner side wall of the vent hole 35 can be, but is not limited to, stainless steel, cast iron, ceramic, aluminum alloy, inorganic glass, magnesium alloy or other metal materials. Preferably, the material of the inner side wall of the vent hole 35 can be the same as the material of the second structure 33, so that the processing of the pot cover 30 is relatively simple. At this time, the strength of the inner side wall of the vent hole 35 is high, the inner side wall of the vent hole 35 is not easy to deform, and the cost of the pot cover 30 is low. In another embodiment, the inner side wall of the vent hole 35 is a silver structure, and the material of the inner side wall of the vent hole 35 is the same as that of at least part of the first structure 31. When the water in the cavity 11 is heated, water vapor is discharged from the vent hole 35, and part of the water vapor will condense and adhere to the inner side wall of the vent hole 35, and the condensed water vapor will enter the cavity 11 again. When this part of water vapor adheres to the inner wall (silver structure) of the vent hole 35, the silver structure will release silver ions, which can sterilize this part of water vapor, thus being beneficial to human health.

[0043] See also Figure 2 and Figure 3The first structure 31 includes two opposite sides, one side of the first structure 31 is used to cover the opening 13 of the kettle body 10, and the other side of the first structure 31 is used to connect with the second structure 33, and the second structure 33 is used to ensure the strength and aesthetics of the kettle cover 30. In the case where at least part of the first structure 31 is a silver structure, the material of the silver structure can be, but is not limited to, pure silver, silver-plated or alloy silver. Preferably, the material of the silver structure of the present application is pure silver. When the electric kettle 100 is powered on to heat water, the water vapor generated after the water is heated will adhere to the first structure 31. When the water vapor contacts the silver structure, the silver structure will release silver ions, which can play a sterilizing role and is beneficial to human health. In addition, the silver ions can soften the water quality, thereby improving the taste of the water. The area of ​​the silver structure of the first structure 31 can be greater than or equal to the area of ​​the opening 13 of the kettle body 10, so that when the water vapor adheres to the kettle cover 30, the water vapor can all contact with the silver structure.

[0044] The material of the second structure 33 can be, but is not limited to, silver, stainless steel, cast iron, ceramics, aluminum alloy, inorganic glass, organic plastic, pure titanium, titanium alloy, magnesium alloy or other metal materials. When the material of the second structure 33 is silver, the appearance of the pot cover 30 is better. When the material of the second structure 33 is stainless steel, cast iron, ceramics, aluminum alloy, inorganic glass, organic plastic, pure titanium, titanium alloy, magnesium alloy or other metal materials, the cost of the pot cover 30 is lower, the strength is higher, and the pot cover 30 is not easily damaged.

[0045] In the electric kettle 100 of the embodiment of the present application, the first structure 31 of the kettle cover 30 faces the cavity 11 of the kettle body 10, and when the kettle cover 30 is installed on the kettle body 10, the first structure 31 covers the opening 13. Since at least part of the first structure 31 is a silver structure, when the substance in the cavity 11 is heated, the silver structure can release silver ions, which can sterilize the substance in the cavity 11, which is beneficial to human health, and the silver ions can also improve the taste of the substance.

[0046] The electric kettle 100 will be further described below with reference to the accompanying drawings.

[0047] See also Figure 2 and Figure 3In some embodiments, the first structure 31 is a silver structure as a whole. In this case, the processing of the first structure 31 is relatively simple. When the water in the cavity 11 is heated, the water vapor adheres to the first structure 31. The first structure 31 can release silver ions to sterilize the water vapor, thereby ensuring the cleanliness and safety of the hot water in the cavity 11. When the first structure 31 is a silver structure as a whole, and the second structure 33 is also a silver structure, the first structure 31 and the second structure 33 can be integrally formed, and the connection between the first structure 31 and the second structure 33 is relatively stable. When the material of the second structure 33 is stainless steel, cast iron, ceramic, aluminum alloy, inorganic glass, organic plastic, pure titanium, titanium alloy, magnesium alloy or other metal materials, the second structure 33 is detachably or non-detachably connected to the first structure 31. Among them, the detachable installation method includes but is not limited to threaded connection, screw connection or snap connection. The non-detachable installation method includes but is not limited to welding, gluing connection or interference fit.

[0048] See also Figure 2 and Figure 3 In other embodiments, the first structure 31 includes a first part and a second part, the first part covers the opening 13, the second part extends from the periphery of the first part and is connected to the top of the kettle body 10, the first part is a silver structure, and the material of the second part is different from that of the first part.

[0049] The area of ​​the first part can be equal to or slightly larger than the opening area of ​​the opening 13, so that when the water in the cavity 11 is heated, the water vapor can adhere to the first part, and the first part can release silver ions to sterilize the water vapor, thereby ensuring the cleanliness and safety of the hot water in the cavity 11. At this time, the area of ​​the silver structure is small, the amount of silver used in the first structure 31 is small, and the cost of the first structure 31 is low.

[0050] The second part is connected to the top of the kettle body 10 so that the first structure 31 is firmly mounted on the top of the kettle body 10. The material of the second part can be, but is not limited to, stainless steel, cast iron, ceramic, aluminum alloy, inorganic glass, organic plastic, pure titanium, titanium alloy, magnesium alloy or other metal materials. In the case where the material of the second structure 33 is not silver, the material of the second part can be the same as the material of the second structure 33, or the material of the second part can be different from the material of the second structure 33. The second part is detachably or non-detachably connected to the first part. Among them, the detachable installation method includes, but is not limited to, threaded connection, screw connection or snap-fit ​​connection. Non-detachable installation methods include, but are not limited to, welding, gluing connection or interference fit.

[0051] The first structure 31 in the embodiment of the present application is entirely a silver structure.

[0052] See also Figure 2In some embodiments, the second structure 33 is provided with a first cavity 331, and the first cavity 331 of the second structure 33 is vacuum or non-vacuum. In the case where the second structure 33 is provided with the first cavity 331, the second structure 33 uses less material, which can save material costs. In addition, the second structure 33 is relatively light as a whole, so that the weight of the pot cover 30 is relatively light, which is convenient for transportation and placement of the pot cover 30.

[0053] In one embodiment, the first cavity 331 is non-vacuum. In this case, the second structure 33 only needs to be processed under normal conditions, and the processing of the second structure 33 is relatively simple. In another embodiment, the first cavity 331 is vacuum. The second structure 33 can be processed under a vacuum environment. At this time, since there are almost no gas molecules in a vacuum environment, heat is difficult to transfer by conduction and convection, so that the heat in the cavity 11 is difficult to lose through the vacuum first cavity 331. The second structure 33 includes two opposite sides, the first side 333 of the second structure 33 is connected to the first structure 31, the second side 335 of the second structure 33 is away from the first structure 31, and the first side 333 and the second side 335 together form the first cavity 331. When the water in the cavity 11 is heated, the heat in the cavity 11 can be transferred to the first side 333 through the first structure 31. When the first cavity 331 is a vacuum, the heat of the first side 333 is difficult to transfer to the second side 335, so that the heat in the cavity 11 can be effectively reduced from being lost from the second side 335 to the outside of the electric kettle 100, and the vacuum first cavity 331 can play a good role in heat preservation of the hot water in the cavity 11. And because the temperature of the second side 335 hardly rises, the problem of scalding when the user takes the pot cover 30 can be avoided. The first cavity 331 of the present application is a vacuum.

[0054] See also Figure 2 and Figure 3 In some embodiments, the kettle body 10 includes an inner liner 15 and an outer liner 17, wherein the inner liner 15 is loaded in the outer liner 17, and the inner liner 15 forms a cavity 11. The inner liner 15 is used to hold and heat water in the electric kettle 100, and the outer liner 17 is used to carry and protect the inner liner 15. The outer liner 17 is also used to ensure the strength and aesthetics of the kettle body 10. Preferably, the outer liner 17 may have certain impact resistance and pressure resistance, so that the kettle body 10 is not easily damaged.

[0055] See also Figure 2 and Figure 3 Specifically, in some embodiments, the inner liner 15 is an integral silver structure, and the inner liner 15 and the first structure 31 together form a silver loading cavity 101. In this case, the processing of the inner liner 15 is relatively simple, the performance of the inner liner 15 is relatively stable, and the service life of the inner liner 15 is also relatively long. The material of the silver structure can be, but is not limited to, pure silver, silver-plated, or alloy silver. Preferably, the material of the silver structure of the present application is pure silver.

[0056] The water in the cavity 11 is in direct contact with the inner liner 15. When the water in the cavity 11 is heated, the silver inner liner 15 can release silver ions. The silver ions enter the water and can kill bacteria in the water. The silver ions can soften the water quality and improve the taste of the water. When the pot cover 30 is installed on the pot body 10, the inner liner 15 and the first structure 31 together form a silver loading cavity 101. The water in the cavity 11 is in contact with the silver inner liner 15, and the water vapor attached to the pot cover 30 is in contact with the silver structure of the first structure 31, so that the parts contacted by the water in the loading cavity 101 are all silver structures. When the loading cavity 101 is a silver structure, the silver structure can release silver ions, so that it can play a good sterilization role on the water in the loading cavity 101, and the taste of the water in the loading cavity 101 is also good. At this time, it is difficult for the water in the loading cavity 101 to contact components of other materials except the silver structure, thereby reducing the negative impact of other materials on the water.

[0057] In other embodiments, the inner wall of the inner liner 15 is provided with a silver layer, and the inner liner 15 and the first structure 31 together form a silver loading cavity 101. The inner wall of the inner liner 15 may also be provided with a silver coating, in which case the amount of silver used in the inner liner 15 is less, and the cost of the inner liner 15 is lower. The inner liner 15 of the embodiment of the present application is an integral silver structure.

[0058] See also Figure 2 and Figure 3 In some embodiments, the material of the outer liner 17 includes at least one of silver, stainless steel, cast iron, ceramic, aluminum alloy, inorganic glass, organic plastic, pure titanium, titanium alloy, and magnesium alloy. Among them, when the material of the outer liner 17 is silver, the aesthetics of the kettle body 10 is better. At this time, the outer liner 17 and the inner liner 15 can be integrally formed. When the material of the outer liner 17 is at least one of stainless steel, cast iron, ceramic, aluminum alloy, inorganic glass, organic plastic, pure titanium, titanium alloy, and magnesium alloy, the cost of the outer liner 17 is low and the strength is high, and the kettle body 10 is not easily damaged. In other embodiments, the outer liner 17 can also be made of other metal materials.

[0059] When the inner pot 15 and the outer pot 17 are made of different materials, when the electric kettle 100 is powered on to heat the water in the cavity 11 , the inner pot 15 and the outer pot 17 will have different expansion rates after being heated, so that relative displacement may occur between the inner pot 15 and the outer pot 17 .

[0060] See also Figure 2 and Figure 3, the connection method between the inner liner 15 and the outer liner 17 in the present application is vacuum welding. Vacuum welding is a welding method for welding in a vacuum environment. Vacuum welding has good welding effect, precise welding temperature control and less welding material usage. The inner liner 15 and the outer liner 17 after vacuum welding can fit tightly, which can avoid the problem of relative displacement between the inner liner 15 and the outer liner 17 after heating. In one embodiment, the inner liner 15 includes a flange, and vacuum welding is performed between the flange and the top of the outer liner 17 to connect the inner liner 15 and the outer liner 17. At this time, vacuum welding only needs to weld the connection between the flange and the top of the outer liner 17. The steps of vacuum welding are relatively simple and the welding efficiency is high. In another embodiment, vacuum welding is performed at the connection positions of the inner liner 15 and the outer liner 17. At this time, the connection between the inner liner 15 and the outer liner 17 is more stable, and there will be no loosening and displacement problems between the inner liner 15 and the outer liner 17.

[0061] In other embodiments, the connection method between the inner liner 15 and the outer liner 17 may also be electronic welding and laser welding. When the connection method between the inner liner 15 and the outer liner 17 is electronic welding, the electronic welding has high weld strength, a small heat-affected zone, and a fast welding speed. When the connection method between the inner liner 15 and the outer liner 17 is laser welding, the laser welding has a small weld width, a small heat-affected zone, and a smooth and beautiful weld.

[0062] See also Figure 2 and Figure 3 In some embodiments, the outer liner 17 is a single-layer structure. In this case, the outer liner 17 uses less material, which can save material costs, and the processing of the outer liner 17 is relatively simple. In other embodiments, the outer liner 17 is a double-layer structure, and the middle of the double-layer structure is a second cavity 173, and the second cavity 173 of the double-layer structure is non-vacuum. In this case, the outer liner 17 only needs to be processed under ordinary conditions, and the processing of the second structure 33 is relatively simple.

[0063] See also Figure 2 and Figure 3In some other embodiments, the outer liner 17 is a double-layer structure, and the middle of the double-layer structure is a second cavity 173, and the second cavity 173 of the double-layer structure is a vacuum. The outer liner 17 can be processed under a vacuum environment. At this time, since there are almost no gas molecules in a vacuum environment, heat is difficult to transfer by conduction and convection, so that the heat in the cavity 11 is difficult to lose through the vacuum second cavity 173. The outer liner 17 includes a first layer 175 and a second layer 177, and the first layer 175 and the second layer 177 together form the second cavity 173. The first layer 175 is connected to the inner liner 15, and the second layer 177 is away from the inner liner 15. When the water in the cavity 11 is heated, the heat in the cavity 11 can be transferred to the first layer 175 through the inner liner 15. When the second cavity 173 is vacuum, the heat of the first layer 175 is difficult to transfer to the second layer 177, so that the heat in the cavity 11 can be effectively reduced from being lost from the second layer 177 to the outside of the electric kettle 100, and the vacuum second cavity 173 can play a good role in keeping the hot water in the cavity 11 warm. In addition, since the temperature of the second layer 177 hardly rises, it can prevent the user from accidentally touching the kettle body 10 and getting scalded.

[0064] In one example, when the first cavity 331 is non-vacuum, the second cavity 173 is non-vacuum. At this time, the processing of the second structure 33 and the outer pot 17 only needs to be processed under ordinary environment, and the processing is relatively simple. In another example, when the first cavity 331 is vacuum, the second cavity 173 is non-vacuum. At this time, the processing of the outer pot 17 is relatively simple. The second structure 33 has a better heat preservation effect, and the heat in the cavity 11 is difficult to dissipate from the second structure 33 to the outside of the electric kettle 100. In another example, when the first cavity 331 is non-vacuum, the second cavity 173 is vacuum. At this time, the processing of the second structure 33 is relatively simple. The outer pot 17 has a better heat preservation effect, and the heat in the cavity 11 is difficult to dissipate from the outer pot 17 to the outside of the electric kettle 100, which can effectively slow down the heat loss of the hot water in the cavity 11, and the hot water can keep the heat for a certain period of time. In another example, when the first cavity 331 is vacuum, the second cavity 173 is vacuum. The second structure 33 has a better heat preservation effect, and the outer pot 17 also has a better heat preservation effect. The second structure 33 and the outer pot 17 wrap the loading cavity 101, so that the heat in the loading cavity 101 is difficult to dissipate to the outside of the electric kettle 100 through the first cavity 331 and the second cavity 173. The heat preservation effect of the electric kettle 100 is better, and the hot water can keep the heat for a longer time. The outer pot 17 of the embodiment of the present application is a double-layer structure, and the first cavity 331 and the second cavity 173 are both vacuum.

[0065] See also Figures 2 to 4In some embodiments, the electric kettle 100 also includes a spout 50, a spacer 171 is provided in the second cavity 173, and the spacer 171 divides the second cavity 173 into a non-connected first area 1731 and a second area 1733, the first area 1731 is a vacuum area, and the second area 1733 is provided with a connecting portion 1735 forming a through hole 19, and the spout 50 extends from the outer tank 17, and the inner cavity of the spout 50 is connected to the inner cavity of the connecting portion 1735.

[0066] The inner cavity of the connecting portion 1735 is a through hole 19, and the through hole 19 is used to connect the inner cavity of the cavity 11 and the inner cavity of the spout 50. The water in the cavity 11 can pass through the through hole 19 and flow out of the inner cavity of the spout 50 to the outside of the electric kettle 100. The spacer 171 is connected to the first layer 175 of the outer liner 17 and the second layer 177 of the outer liner 17. The connection method of the spacer 171 to the first layer 175 of the outer liner 17 and the second layer 177 of the outer liner 17 can be welding or gluing. The first area 1731 is a vacuum area, and the second area 1733 is a non-vacuum area. The area of ​​the inner liner 15 covered by the first area 1731 is larger than the area of ​​the inner liner 15 covered by the second area 1733, so that the first area 1731 has a better insulation effect on the hot water in the inner liner 15. The spout 50 is installed in the second area 1733 and corresponds to the position of the through hole 19. The spacer 171 can enhance the strength between the first layer 175 of the outer liner 17 and the second layer 177 of the outer liner 17, so that when the spout 50 is installed on the outer liner 17, the outer liner 17 is not easily deformed. The vacuum area of ​​the outer liner 17 can be processed and formed under a vacuum environment. After the spacer 171 separates the first area 1731 and the second area 1733, the connection between the spout 50 and the outer liner 17 can be processed under a normal environment, and the processing of the spout 50 and the outer liner 17 is relatively simple.

[0067] See also Figures 2 to 4 In some embodiments, in the height direction H of the electric kettle 100, a through hole 19 penetrating the side wall of the kettle body 10 is provided near the top of the kettle body 10, and the spout 50 extends from the top of the outer pot 17 of the kettle body 10 toward the center away from the cavity 11, and the inner cavity of the spout 50 is connected with the cavity 11 through the through hole 19 and the opening 13.

[0068] Among them, the spout 50 and the outer liner 17 are an integral structure, and the spout 50 and the outer liner 17 can be integrally formed. At this time, the connection between the spout 50 and the outer liner 17 is relatively stable, and the spout 50 is not easy to fall off from the kettle body 10. The through hole 19 is used to connect the inner cavity of the spout 50 with the opening 13. When the water in the cavity 11 needs to be poured out from the spout 50, the water in the cavity 11 passes through the opening 13 and the through hole 19, and flows out of the electric kettle 100 from the inner cavity of the spout 50. The opening shape of the through hole 19 can be, but is not limited to, a circle, an ellipse, a triangle, a quadrilateral or other polygonal structures. In one example, the number of the through hole 19 is one. At this time, the opening area of ​​the through hole 19 can be less than or equal to the area of ​​the connection between the spout 50 and the outer liner 17, so that the water flowing out of the through hole 19 can all flow into the inner cavity of the spout 50. In another example, the number of the through holes 19 can be multiple, and the multiple through holes 19 are all connected to the inner cavity of the spout 50. The opening area of ​​the through holes 19 is small, and the multiple through holes 19 are spaced apart. At this time, when the through holes 19 allow the water in the cavity 11 to enter the inner cavity of the spout 50, the through holes 19 can also filter the solids (such as tea leaves and fruits, etc.) in the cavity 11, thereby preventing the solids in the cavity 11 from flowing out of the spout 50.

[0069] See also Figures 2 to 4 In other embodiments, in the height direction H of the electric kettle 100, a through hole 19 penetrating the side wall of the kettle body 10 is provided near the top of the kettle body 10, and the spout 50 is installed on the outside of the outer pot 17 of the kettle body 10 and surrounds the through hole 19, so that the inner cavity of the spout 50 is connected with the cavity 11 through the through hole 19.

[0070] The spout 50 and the kettle body 10 are separate structures, and the spout 50 is detachably or non-detachably installed on the kettle body 10. The detachable installation method includes but is not limited to threaded connection, screw connection or snap-on connection. Non-detachable installation methods include but are not limited to welding, gluing connection or interference fit. In the case where the spout 50 is detachably installed on the kettle body 10, the spout 50 can be easily removed for cleaning and replacement. The material of the spout 50 can be but is not limited to silver, stainless steel, cast iron, ceramic, aluminum alloy, inorganic glass, organic plastic, pure titanium, titanium alloy, magnesium alloy or other metal materials, and the material of the spout 50 can be the same as or different from that of the kettle body 10. The area of ​​the connection between the spout 50 and the outer liner 17 can be larger than the opening area of ​​the through hole 19, so that all the water flowing out of the through hole 19 can flow into the inner cavity of the spout 50.

[0071] See also Figures 2 to 4In some other embodiments, in the height direction H of the electric kettle 100, a through hole 19 penetrating the side wall of the kettle body 10 is provided at a position near the bottom of the kettle body 10, and the spout 50 is installed on the outer pot 17 of the kettle body 10 and surrounds the through hole 19, so that the inner cavity of the spout 50 is connected with the cavity 11 through the through hole 19, and the extension direction of the spout 50 is inclined relative to the height direction H of the electric kettle 100. Since the through hole 19 is close to the bottom position of the kettle body 10, after the spout 50 is connected with the outer pot 17, the spout 50 can be inclined relative to the height direction H of the electric kettle 100. In the height direction H of the electric kettle 100, the top of the spout 50 is higher than the height of the highest liquid level in the kettle body 10, so that the water in the cavity 11 is not easy to overflow from the spout 50.

[0072] See also Figures 2 to 4 In some further embodiments, in the height direction H of the electric kettle 100, the spout 50 is a protruding structure extending from the top of the outer liner 17 of the kettle body 10 toward the center direction away from the cavity 11, and the inner cavity of the spout 50 is connected to the cavity 11. At this time, the spout 50 may be a leaking spout structure extending from the outer liner 17. When the water in the cavity 11 needs to be poured out, the water in the cavity 11 can directly flow into the inner cavity of the spout 50 and flow out from the inner cavity of the spout 50. The spout 50 may be an open structure or an annular structure. The spout 50 and the outer liner 17 may be an integral structure, and the connection between the spout 50 and the outer liner 17 is relatively stable. In addition, there is no need to set the through hole 19 on the side wall of the kettle body 10, the structure of the kettle body 10 is simpler, and the processing of the kettle body 10 is relatively simple.

[0073] See also Figure 2 and Figure 3 Furthermore, in some embodiments, the electric kettle 100 also includes a heating element 70, and a mounting groove 18 is provided on the side of the bottom of the kettle body 10 facing away from the cavity 11, and the heating element 70 is installed in the mounting groove 18, and the surface of the heating element 70 does not exceed the bottom surface of the kettle body 10, and the heating element 70 is used to provide heat to the kettle body 10.

[0074] Among them, when the heating element 70 is accommodated in the mounting groove 18, the overall volume of the electric kettle 100 is small and easy to store. The heating element 70 is arranged at the bottom of the kettle body 10. When it is necessary to heat the water in the cavity 11, the electric kettle 100 is electrically connected to the external power supply, and the current flows through the heating element 70. The heating element 70 can generate heat, and the heat is transferred from the outer pot 17 to the inner pot 15. Since the silver inner pot 15 has good thermal conductivity, the heat at the bottom of the inner pot 15 can be quickly transferred to the entire inner pot 15, and the inner pot 15 then transfers the heat to the water in the cavity 11, so that the water in the cavity 11 can be quickly heated, and each position of the water in the cavity 11 is heated more evenly.

[0075] See also Figures 1 to 3The electric kettle 100 further includes a switch 80, which is used to turn on and off the connection between the external power supply and the electric kettle 100. Exemplarily, the switch 80 may be a steam switch 80, which is used to manually press the switch 80 when heating is required to electrically connect the external power supply to the electric kettle 100. When the water in the cavity 11 is heated to generate steam, when the steam pressure reaches a certain value, the steam will push the steam switch 80 to automatically turn off the electrical connection between the electric kettle 100 and the external power supply. The steam switch 80 can prevent the water in the cavity 11 from drying up or being overheated.

[0076] See also Figures 1 to 4 The electric kettle 100 further includes a handle 90, which is connected to the kettle body 10. The handle 90 is provided to facilitate the taking and placing of the kettle body 10. The handle 90 of the present application is fixedly connected to the kettle body 10, and the handle 90 cannot rotate relative to the kettle body 10. At this time, the handle can not only facilitate the user to take and place the kettle body 10, but also increase the aesthetics of the electric kettle 100.

[0077] In the electric kettle 100 of the embodiment of the present application, the first structure 31 of the kettle cover 30 faces the cavity 11 of the kettle body 10, and when the kettle cover 30 is installed on the kettle body 10, the first structure 31 covers the opening 13. Since at least part of the first structure 31 is a silver structure, when the substance in the cavity 11 is heated, the silver structure can release silver ions, which can sterilize the substance in the cavity 11, which is beneficial to human health, and the silver ions can also improve the taste of the substance.

[0078] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. At the same time, other implementation methods can be derived from the above-mentioned embodiments, so that structural and logical replacements and changes can be made without departing from the scope of this disclosure.

[0079] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
