The material of the kettle cover of the electric kettle is usually made of stainless steel materials, and the stainless steel materials are lighter in weight and lower in cost. However, the stainless steel material contains various metal elements, and in the case of heating water by an electric kettle, water vapor generated after the water is heated may adhere to the kettle cover, and high-temperature water vapor may chemically react with the metal elements in the stainless steel (kettle cover). At this time, the condensed water vapor falls into the kettle body to affect the water quality in the electric kettle, so that the taste of the water is poor and even the health of a human body is affected. To address this problem, embodiments of the present application provide an electric kettle 100 (shown in fig. 1).

Referring to fig. 1 to 3, an electric kettle 100 according to an embodiment of the present application includes a kettle body 10 and a kettle lid 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 mounted on the kettle body 10 and covers the opening 13, the kettle cover 30 comprises a first structure 31 and a second structure 33, the first structure 31 is connected with the top of the kettle body 10, the second structure 33 is connected with the first structure 31 and is positioned on one side of the first structure 31 away from the cavity 11, and at least part of the first structure 31 is of a silver structure.

Specifically, the electric kettle 100 is a structure for being energized to heat a substance loaded inside the electric kettle 100. The substances loaded inside the electric kettle 100 may be, but are not limited to, liquids, solids, or solid-liquid mixtures, etc. Wherein the liquid includes, but is not limited to, water, coffee, milk, oil, etc., the solid-liquid mixture includes tea (water+tea), scented tea, nectar, etc., and the solid includes coffee beans, tea, candy, etc. In the present application, water is loaded in the electric kettle 100, and the electric kettle 100 can be powered on to heat the water in the electric kettle 100.

The cavity 11 of the kettle body 10 is used for supplying water to be loaded therein, and water is loaded into the cavity 11 from the opening 13 in the case of heating water. In the case that the electric kettle 100 is powered on, the kettle body 10 serves to transfer heat generated from the heating member 70 of the electric kettle 100 to various positions of 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 is not limited to, circular, oval, triangular, quadrilateral, or other polygonal. The volume of the cavity 11 may be, but is not limited to, 0.5L, 0.8L, 1.2L, 1.5L, 1.7L, 1.8L, 2L, 3L, 3.5L, 4L, etc. In the case where the volume of the chamber 11 is small (for example, 0.5L or 0.8L), less water can be loaded in the chamber 11. In the case of the electric kettle 100 being energized, water in the cavity 11 can be heated up quickly. When the volume of the chamber 11 is large (for example, 2L or 3L), the amount of water that can be loaded in the chamber 11 is large, and the amount of water that can be heated at one time by the electric kettle 100 is large.

The pot lid 30 is mounted on top of the pot body 10 and covers the opening 13. The shape of the lid 30 may be, but is not limited to, circular, oval, triangular, quadrilateral, or other polygonal, etc., and preferably the lid 30 is the same shape as the opening 13 so that the lid 30 can better fit the opening 13. The kettle cover 30 covers the opening 13 of the kettle body 10, so that external dust or impurities can be prevented from entering the cavity 11, and the cleaning of water in the cavity 11 can be ensured. In the case that the water in the cavity 11 is heated, the pot lid 30 can also prevent high-temperature water vapor from directly escaping from the opening 13, and the problem of scalding the user can be avoided. In addition, the kettle cover 30 can also play a certain heat preservation effect on the hot water in the cavity 11, and the kettle cover 30 can slow down the heat dissipation of the hot water, so that the hot water can keep a certain time of heat.

The lid 30 is further provided with a vent hole 35, the vent hole 35 penetrates through the first structure 31 and the second structure 33, and the vent hole 35 is used for communicating the cavity 11 with the outside. In the case that the water in the cavity 11 is heated, the vent hole 35 is used for discharging water vapor to the outside of the cavity 11, so that the air pressure in the cavity 11 can be balanced, and the problem of explosion caused by the excessively high air pressure in the cavity 11 is avoided. Meanwhile, under the condition that the kettle body 30 needs to pour water, the air pressure in the cavity 11 can be balanced through the air holes 35, so that the kettle body 30 can pour water more stably. The problem that water flows fast when the air pressure in the cavity 11 is too high can be avoided when the kettle body 30 is used for pouring water, and the problem that water cannot flow out when the air pressure in the cavity 11 is too low can also be avoided. The vent holes 35 may be formed in a circular, oval, triangular, quadrilateral or other polygonal shape.

In one embodiment, the material of the inner side wall of the vent hole 35 may be, but not limited to, stainless steel, cast iron, ceramic, aluminum alloy, inorganic glass, magnesium alloy, or other metal material. Preferably, the material of the inner side wall of the vent hole 35 is the same as that of the second structure 33, so that the processing of the pot lid 30 is 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 lid 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 the material of at least part of the first structure 31. In the case where the water in the cavity 11 is heated, the water vapor is discharged from the vent hole 35, a part of the water vapor is condensed and adhered to the inner side wall of the vent hole 35, and the condensed water vapor enters the cavity 11 again. In the case where the part of the water vapor adheres to the inner side wall (silver structure) of the vent hole 35, silver ions are released from the silver structure, and the silver ions can play a role in sterilizing the part of the water vapor, thereby being beneficial to human health.

Referring to fig. 2 and 3, the first structure 31 includes two opposite sides, one side of the first structure 31 is used for covering the opening 13 of the kettle body 10, the other side of the first structure 31 is used for being connected with the second structure 33, and the second structure 33 is used for ensuring the strength and the aesthetic property of the kettle lid 30. In the case where at least part of the first structure 31 is a silver structure, the material of the silver structure may be, but is not limited to, pure silver, silver plating, or alloy silver. Preferably, the silver structure of the present application is made of pure silver. In the case that the electric kettle 100 is energized to heat water, water vapor generated after the water is heated may adhere to the first structure 31. When the water vapor contacts with the silver structure, the silver structure can release silver ions, the silver ions can play a role in sterilization, the human health is benefited, and the silver ions can soften water quality, so that the taste of the water can be improved. The area of the silver structure of the first structure 31 may be greater than or equal to the area of the opening 13 of the kettle body 10 so that the water vapor can be entirely in contact with the silver structure when the water vapor is adhered to the kettle lid 30.

The material of the second structure 33 may be, but 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. In the case where the material of the second structure 33 is silver, the lid 30 has a good aesthetic appearance. When the second structure 33 is made of stainless steel, cast iron, ceramic, aluminum alloy, inorganic glass, organic plastic, pure titanium, titanium alloy, magnesium alloy or other metal materials, the cost of the kettle cover 30 is low, the strength is high, and the kettle cover 30 is not easy to damage.

In the electric kettle 100 according to the embodiment of the present application, the first structure 31 of the kettle lid 30 faces the cavity 11 of the kettle body 10, and the first structure 31 covers the opening 13 when the kettle lid 30 is mounted on the kettle body 10. Since at least part of the first structure 31 is a silver structure, in the case that the substance in the cavity 11 is heated, the silver structure can release silver ions, which can play a role in sterilizing the substance in the cavity 11, is beneficial to human health, and can also improve the taste of the substance.

The electric kettle 100 is further described below with reference to the drawings.

Referring to fig. 2 and 3, in some embodiments, the first structure 31 is a silver structure as a whole. At this time, the processing of the first structure 31 is relatively simple. In case the water in the cavity 11 is heated, water vapor adheres to the first structure 31. The first structure 31 can release silver ions to sterilize the water vapor, thereby ensuring the cleaning and safety of the hot water in the cavity 11. Under the condition that the whole first structure 31 is of a silver structure and the second structure 33 is of 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 stable. In the case where 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 material, the second structure 33 is detachably or non-detachably connected to the first structure 31. Wherein, the detachable installation mode comprises but is not limited to screw connection, screw connection or clamping connection and the like. Non-removable mounting means include, but are not limited to, welding, glue connection, interference fit, or the like.

Referring to fig. 2 and 3, in other embodiments, the first structure 31 includes a first portion and a second portion, the first portion covers the opening 13, the second portion extends from a periphery of the first portion and is connected to a top of the kettle body 10, the first portion is a silver structure, and a material of the second portion is different from that of the first portion.

The area of the first portion may be equal to or slightly larger than the opening area of the opening 13, so that under the condition that the water in the cavity 11 is heated, the water vapor can be attached to the first portion, and the first portion can release silver ions to sterilize the water vapor, so that the cleaning and safety of the hot water in the cavity 11 can be ensured. 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.

The second portion is connected to the top of the kettle body 10 such that the first structure 31 is securely mounted to the top of the kettle body 10. The material of the second portion may be, but not limited to, stainless steel, cast iron, ceramics, 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 portion may be the same as that of the second structure 33, and the material of the second portion may be different from that of the second structure 33. The second portion is removably or non-removably connected to the first portion. Wherein, the detachable installation mode comprises but is not limited to screw connection, screw connection or clamping connection and the like. Non-removable mounting means include, but are not limited to, welding, glue connection, interference fit, or the like.

The first structure 31 according to the embodiment of the present application has a silver structure as a whole.

Referring to fig. 2, in 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 material consumption of the second structure 33 is less, so that the material cost can be saved. And the second structure 33 is lighter in weight as a whole, so that the kettle cover 30 is lighter in weight, and the transportation and the taking of the kettle cover 30 are facilitated.

In one embodiment, the first cavity 331 is non-vacuum. At this time, the second structure 33 is only required to be processed in a normal environment, and the processing of the second structure 33 is relatively simple. In another embodiment, the first cavity 331 is a vacuum. The second structure 33 may be processed in a vacuum environment. At this time, since there are almost no gas molecules in the vacuum environment, heat is difficult to transfer by conduction and convection, so that heat in the cavity 11 is difficult to be lost through the first cavity 331 of the vacuum. The second structure 33 includes opposite sides, a first side 333 of the second structure 33 is connected to the first structure 31, a second side 335 of the second structure 33 faces away from the first structure 31, and the first side 333 and the second side 335 together form a first cavity 331. In case the water in the cavity 11 is heated, heat in the cavity 11 may be transferred to the first side 333 via the first structure 31. Under the condition that the first cavity 331 is vacuum, heat of the first side 333 is difficult to transfer to the second side 335, so that heat dissipation from the second side 335 to the outside of the electric kettle 100 in the cavity 11 can be effectively reduced, and the vacuum first cavity 331 can play a good role in heat preservation for hot water in the cavity 11. And because the temperature of the second side 335 is hardly increased, the problem of scalding when the user holds the kettle lid 30 can be avoided. The first cavity 331 of the present application is a vacuum.

Referring to fig. 2 and 3, in some embodiments, the kettle body 10 includes a liner 15 and an outer liner 17, the liner 15 is mounted in the outer liner 17, and the liner 15 forms the cavity 11. Wherein, the inner container 15 is used for holding and heating water in the electric kettle 100, the outer container 17 is used for carrying and protecting the inner container 15, and the outer container 17 is also used for ensuring the strength and the aesthetic property of the kettle body 10. Preferably, the outer bladder 17 may have a certain impact resistance and compression resistance, so that the kettle body 10 is not easily damaged.

Referring to fig. 2 and 3, in particular, in some embodiments, the liner 15 is of an overall silver structure, and the liner 15 and the first structure 31 together define a silver loading chamber 101. At this time, the processing of the liner 15 is simple, the performance of the liner 15 is stable, and the service life of the liner 15 is long. The silver structure may be made of pure silver, silver plating, alloy silver, or the like. Preferably, the silver structure of the present application is made of pure silver.

The water in the cavity 11 is in direct contact with the inner container 15, under the condition that the water in the cavity 11 is heated, the silver inner container 15 can release silver ions, the silver ions enter the water, bacteria in the water can be eliminated, the silver ions can soften the water quality, and the taste of the water can be improved. When the pot lid 30 is mounted on the pot body 10, the inner container 15 and the first structure 31 together enclose a silver loading cavity 101. The water in the cavity 11 contacts with the silver inner container 15, and the water vapor attached to the pot lid 30 contacts with the silver structure of the first structure 31, so that the contact parts of the water in the loading cavity 101 are all silver structures. In the case that the loading cavity 101 is of a silver structure, silver ions can be released by the silver structure, so that a good sterilization effect can be achieved on water in the loading cavity 101, and the taste of the water in the loading cavity 101 is good. At this time, the water in the loading chamber 101 is difficult to contact with the elements made of materials other than the silver structure, so that the negative influence of the other materials on the water can be reduced.

In other embodiments, the inner wall of the liner 15 is provided with a silver layer, and the liner 15 and the first structure 31 together enclose a silver loading chamber 101. The inner wall of the inner container 15 may be provided with a silver coating, and at this time, the amount of silver used in the inner container 15 is small, and the cost of the inner container 15 is low. The liner 15 according to the embodiment of the present application has an overall silver structure.

Referring to fig. 2 and 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. When the outer liner 17 is silver, the appearance of the kettle body 10 is good. At this time, the outer liner 17 and the inner liner 15 may be integrally formed. In the case that the material of the outer container 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 outer container 17 has lower cost and higher strength, and the kettle body 10 is not easy to damage. In other embodiments, the outer bladder 17 may be made of other metal materials.

Under the condition that the materials of the inner container 15 and the outer container 17 are different, when the electric kettle 100 is electrified to heat the water in the cavity 11, the inner container 15 and the outer container 17 have different expansion rates after being heated, so that relative displacement can be generated between the inner container 15 and the outer container 17.

Referring to fig. 2 and 3, the inner container 15 and the outer container 17 are connected by vacuum welding. The vacuum welding is a welding mode for welding under a vacuum environment, and has the advantages of good welding effect, accurate welding temperature control and less welding material consumption. The vacuum welded inner container 15 and the outer container 17 can be tightly attached, so that the problem that the inner container 15 and the outer container 17 are relatively displaced after being heated can be avoided. In one embodiment, the liner 15 includes a flange that is vacuum welded to the top of the outer liner 17 to connect the liner 15 to the outer liner 17. At this time, the vacuum welding is only needed to weld the junction of the flange and the top of the outer container 17, the vacuum welding step is simpler, and the welding efficiency is higher. In another embodiment, the connection positions of the inner container 15 and the outer container 17 are all vacuum welded. At this time, the connection between the inner container 15 and the outer container 17 is more stable, and the loosening and displacement between the inner container 15 and the outer container 17 cannot occur.

In other embodiments, the connection between the inner container 15 and the outer container 17 may be electronic welding, laser welding, or the like. In the case where the inner liner 15 and the outer liner 17 are connected by electron welding, the welding joint strength of the electron welding is high, the heat affected zone is small, and the welding speed is high. In the case of laser welding the connection between the inner liner 15 and the outer liner 17, the laser welding has small weld width, small heat affected zone, and smooth and beautiful weld.

Referring to fig. 2 and 3, in some embodiments, the outer liner 17 has a single-layer structure. At this time, the material consumption of the outer liner 17 is small, the material cost can be saved, and the processing of the outer liner 17 is simple. In other embodiments, the outer bladder 17 has a double-layer structure with a second cavity 173 in between, and the second cavity 173 of the double-layer structure is not vacuum. At this time, the outer liner 17 is only required to be processed in a normal environment, and the processing of the second structure 33 is relatively simple.

Referring to fig. 2 and 3, in still other embodiments, the outer liner 17 has a double-layer structure, a second cavity 173 is formed between the double-layer structure, and the second cavity 173 has a vacuum. The outer bladder 17 may be manufactured in a vacuum environment. At this time, since there are almost no gas molecules in the vacuum environment, heat is difficult to transfer by conduction and convection, so that heat in the chamber 11 is difficult to be lost through the vacuum second cavity 173. Bladder 17 includes a first layer 175 and a second layer 177, and first layer 175 and second layer 177 cooperate to form a second cavity 173. The first layer 175 is connected to the liner 15 and the second layer 177 faces away from the liner 15. In the event that the water in the cavity 11 is heated, heat in the cavity 11 may be transferred through the liner 15 to the first layer 175. Under the condition that 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 dissipation from the second layer 177 to the outside of the electric kettle 100 in the cavity 11 can be effectively reduced, and the vacuum second cavity 173 can perform a better heat preservation function on the hot water in the cavity 11. And the temperature of the second layer 177 is hardly increased, so that the situation that a user bumps into the kettle body 10 by mistake and scalds the kettle body can be avoided.

In one example, where the first cavity 331 is non-vacuum, the second cavity 173 is non-vacuum. At this time, the second structure 33 and the outer liner 17 are processed only in a normal environment, so that the processing is simple. In another example, where the first cavity 331 is a vacuum, the second cavity 173 is a non-vacuum. In this case, the outer liner 17 is relatively easy to process. The heat preservation effect of the second structure 33 is good, and heat in the cavity 11 is difficult to be dissipated from the second structure 33 to the outside of the electric kettle 100. In yet another example, where the first cavity 331 is non-vacuum, the second cavity 173 is vacuum. In this case, the second structure 33 is relatively easy to process. The heat preservation effect of the outer container 17 is good, heat in the cavity 11 is difficult to be emitted out of the electric kettle 100 from the outer container 17, heat dissipation of hot water in the cavity 11 can be effectively slowed down, and the hot water can keep a certain time of heat. In yet another example, where the first cavity 331 is a vacuum, the second cavity 173 is a vacuum. The heat-insulating effect of the second structure 33 is better, and the heat-insulating effect of the outer bladder 17 is also better. The second structure 33 and the outer bladder 17 wrap the loading cavity 101, so that heat in the loading cavity 101 is difficult to be dissipated 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 hot water can be kept at a longer temperature. The outer bladder 17 of the embodiment of the present application has a double-layer structure, and the first cavity 331 and the second cavity 173 are both vacuum.

Referring to fig. 2 to 4, in some embodiments, the electric kettle 100 further includes a spout 50, a spacer 171 is disposed in the second cavity 173, the spacer 171 separates the second cavity 173 into a first area 1731 and a second area 1733 that are not communicated, the first area 1731 is a vacuum area, the second area 1733 is provided with a connection portion 1735 forming a through hole 19, the spout 50 extends from the outer container 17, and an inner cavity of the spout 50 is communicated with an inner cavity of the connection portion 1735.

The inner cavity of the connecting portion 1735 is a through hole 19, and the through hole 19 is used for communicating the cavity 11 with the inner cavity of the spout 50. The water in the cavity 11 can flow out of the electric kettle 100 through the through hole 19 and from the inner cavity of the spout 50. The spacer 171 is connected to both the first layer 175 of the outer bladder 17 and the second layer 177 of the outer bladder 17, and the spacer 171 may be connected to the first layer 175 of the outer bladder 17 and the second layer 177 of the outer bladder 17 by welding or gluing, etc. The first region 1731 is a vacuum region and the second region 1733 is a non-vacuum region. The area of the inner container 15 covered by the first area 1731 is larger than the area of the inner container 15 covered by the second area 1733, so that the first area 1731 has a better heat preservation effect on hot water in the inner container 15. The spout 50 is mounted in the second region 1733 and corresponds to the location of the through aperture 19, and the spacer 171 enhances the strength between the first layer 175 of the outer container 17 and the second layer 177 of the outer container 17 so that the outer container 17 is not easily deformed when the spout 50 is mounted in the outer container 17. The vacuum region of the bladder 17 may be formed by processing in a vacuum environment. After the first area 1731 and the second area 1733 are separated by the spacer 171, the connection between the spout 50 and the outer container 17 can be processed in a common environment, and the spout 50 and the outer container 17 can be processed more simply.

Referring to fig. 2 to 4, in some embodiments, in the height direction H of the electric kettle 100, a through hole 19 penetrating through a sidewall of the kettle body 10 is provided at a position of the kettle body 10 near the top, the spout 50 extends from the top of the outer container 17 of the kettle body 10 toward a center direction away from the cavity 11, and an inner cavity of the spout 50 is communicated with the cavity 11 through the through hole 19 and the opening 13.

Wherein, the spout 50 and the outer container 17 are in an integrated structure, and the spout 50 and the outer container 17 can be integrally formed. At this time, the connection between the spout 50 and the outer container 17 is stable, and the spout 50 is not easy to fall off from the kettle body 10. The through hole 19 is used for communicating the inner cavity of the spout 50 with the opening 13, and in the case that the water in the cavity 11 needs to be poured out of 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 may be, but is not limited to, a circular shape, an oval shape, a triangular shape, a quadrangular shape, or other polygonal structures. In one example, the number of through holes 19 is one. At this time, the opening area of the through hole 19 may be smaller than or equal to the area of the joint between the spout 50 and the outer container 17, so that water flowing out of the through hole 19 can flow into the inner cavity of the spout 50. In another example, the number of through holes 19 may be plural, and the plurality of through holes 19 are all in communication with the inner cavity of the spout 50. The opening area of the through holes 19 is small, and the through holes 19 are distributed at intervals. At this time, when water in the cavity 11 enters the inner cavity of the spout 50, the through hole 19 can also filter solids (such as tea and fruit) in the cavity 11, so that the solids in the cavity 11 can be prevented from flowing out of the spout 50.

Referring to fig. 2 to 4, in other embodiments, in the height direction H of the electric kettle 100, a through hole 19 penetrating through a sidewall of the kettle body 10 is provided at a position of the kettle body 10 near the top, and the spout 50 is mounted on an outer side of the outer container 17 of the kettle body 10 and surrounds the through hole 19, so that an inner cavity of the spout 50 is communicated with the cavity 11 through the through hole 19.

Wherein, the spout 50 and the kettle body 10 are in a split structure, and the spout 50 is detachably or non-detachably arranged on the kettle body 10. Wherein, the detachable installation mode comprises but is not limited to screw connection, screw connection or clamping connection and the like. Non-removable mounting means include, but are not limited to, welding, glue connection, interference fit, or the like. In the case where the spout 50 is removably mounted to the spout body 10, the spout 50 may be conveniently removed for cleaning and replacement. The material of the spout 50 may be, but 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 may be the same as or different from the material of the kettle body 10. The area of the joint of the spout 50 and the outer container 17 can be larger than the opening area of the through hole 19, so that the water flowing out of the through hole 19 can flow into the inner cavity of the spout 50 completely.

Referring to fig. 2 to 4, in still other embodiments, in the height direction H of the electric kettle 100, a through hole 19 penetrating through a sidewall of the kettle body 10 is provided at a position of the kettle body 10 near the bottom, and the spout 50 is mounted on the outer container 17 of the kettle body 10 and surrounds the through hole 19, so that the inner cavity of the spout 50 is communicated with the cavity 11 through the through hole 19, and the extending direction of the spout 50 is inclined relative to the height direction H of the electric kettle 100. Because the through hole 19 is close to the bottom of the kettle body 10, the spout 50 can be arranged obliquely relative to the height direction H of the electric kettle 100 after the spout 50 is connected with the outer container 17. In the height direction H of the electric kettle 100, the top of the spout 50 is higher than the highest liquid level in the kettle body 10, so that water in the cavity 11 is not easy to overflow from the spout 50.

Referring to fig. 2 to 4, in still other embodiments, in the height direction H of the electric kettle 100, the spout 50 is a protruding structure with the top of the outer container 17 of the kettle body 10 extending away from the center of the cavity 11, and the inner cavity of the spout 50 is in communication with the cavity 11. In this case, the spout 50 may be a spout structure extending from the outer container 17. In the case where 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 of the inner cavity of the spout 50. The spout 50 may be of an open configuration or may be of a ring-like configuration. The spout 50 and the outer container 17 can be in an integrated structure, and the spout 50 and the outer container 17 are connected firmly. And the side wall of the kettle body 10 does not need to be provided with a through hole 19, the structure of the kettle body 10 is simpler, and the processing of the kettle body 10 is simpler and more convenient.

Referring to fig. 2 and 3, in further embodiments, the electric kettle 100 further includes a heating element 70, a side of the bottom of the kettle body 10 facing away from the cavity 11 is provided with a mounting groove 18, the heating element 70 is mounted on the mounting groove 18, 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 for providing heat to the kettle body 10.
