Description

Technical Field

[0001] This utility model relates to the field of electric kettle technology, specifically to the kettle base assembly and the electric kettle. Background Technology

[0002] Related technologies include electric kettles that automatically add water based on the amount of water remaining in the kettle. The kettle's base assembly includes a weighing component. When the water level reaches a preset low level, it automatically adds water; when the water level reaches a preset high level, it automatically stops adding water. Positioning the weighing component below the coupler allows for more accurate weighing and precise control of water addition. However, because the coupler needs to float vertically, as the weight inside the kettle increases, it causes the coupler to move downwards, deforming the weighing component. Therefore, the kettle base assembly has gaps to allow the coupler to float. This allows water to enter the kettle base assembly through these gaps, potentially causing a hazard as electrical components are located inside. Utility Model Content

[0003] In view of this, the present invention provides a kettle base assembly and an electric kettle to solve the problem that water can easily enter the kettle base assembly through gaps.

[0004] In a first aspect, this utility model provides a kettle base assembly for an electric kettle, comprising:

[0005] The panel structure includes an upwardly protruding water-retaining rib, the inner side of which forms a mounting through hole.

[0006] Beneficial effects: Because the panel structure includes upward-protruding water-blocking ribs, which have the function of blocking water, they can prevent water from entering the mounting through-hole, thereby preventing water from entering the kettle seat assembly through the mounting through-hole and causing danger.

[0007] In one alternative embodiment, the kettle seat assembly further includes:

[0008] A coupler is buoyantly disposed within the mounting through hole;

[0009] The upper pressure ring includes an upper pressure ring and a lower pressure ring. The upper pressure ring includes a surrounding edge located above the panel structure and covering the water-blocking rib. The lower pressure ring is located on the lower side of the panel structure. The upper pressure ring and the lower pressure ring are fixedly connected and clamp the coupler in the middle. The lower pressure ring is connected to a weighing sensor.

[0010] A support plate is fixed to the lower side of the panel structure, and the support plate is provided with clearance holes;

[0011] The weighing sensor includes a fixed end and a deformation part. The fixed end is fixed to the support plate, and the deformation part is movable along the relief hole. The deformation part is fixed to the lower pressure ring.

[0012] Beneficial effects: When the kettle body is placed in the kettle base assembly, the bottom of the kettle body couples with the coupler. Because the kettle body and the water inside have a certain weight, they exert downward pressure on the coupler. Since the upper and lower pressure rings are fixedly connected and clamp the coupler in the middle, the upper and lower pressure rings move downwards with the coupler. Because the lower pressure ring is connected to a load cell, it causes the load cell to deform, thus accurately measuring the amount of water in the kettle body. Since the weight of the kettle body is directly transmitted to the load cell, it is less susceptible to external interference, thus improving measurement accuracy. In addition, the upper pressure ring includes a surrounding edge located above the panel structure that covers the water-blocking ribs. This surrounding edge also serves to block water, preventing water from entering the kettle base assembly through the mounting holes and causing a hazard.

[0013] Because the upper pressure ring and the lower pressure ring are fixedly connected and the coupler is clamped in the middle, the assembly method of the upper pressure ring, the lower pressure ring and the coupler is simple and easy to assemble.

[0014] In one optional embodiment, the pressure ring is provided with a water guide groove, which communicates with the mounting through hole.

[0015] Beneficial effect: By setting a water guide groove in the pressure ring, the water guide groove is connected to the mounting through hole. Therefore, if water enters the mounting through hole, it will fall into the water guide groove, preventing water droplets from falling onto the electrical components inside the kettle seat assembly.

[0016] In one optional embodiment, the pressure ring is further provided with a water guide pipe, which is connected to the water guide groove.

[0017] Beneficial effects: By setting up a water guide pipe that is connected to the water guide trough, water falling into the water guide trough will flow into the water guide pipe and be guided to a location away from electrical components. The combination of the water guide pipe and the water guide trough can effectively prevent water from entering the kettle base assembly and causing danger.

[0018] In one optional embodiment, the bottom surface of the water guide channel is an inclined surface, and the water guide pipe is connected to the lowest point of the water guide channel.

[0019] Beneficial effects: Since the bottom of the water guide channel is sloping, when water falls into the water guide channel, it will flow down the slope. The water guide pipe is connected to the lowest point of the water guide channel, so it can ensure that all the water in the water guide channel can flow to the water guide pipe, which can effectively prevent water from entering the kettle seat assembly and causing danger.

[0020] In one optional embodiment, the lower pressure ring is provided with a rib, the rib abuts against the coupler, and the water guide groove is provided on the outer periphery of the rib.

[0021] Beneficial effect: The ribs of the pressure ring abut against the coupler, which can prevent water from flowing down to the center of the pressure ring.

[0022] In one optional embodiment, the gap between the edging and the panel structure is D1, and the gap between the upper pressure ring and the top of the water-blocking rib is D2. Both D1 and D2 are greater than the deformation distance of the weighing sensor when the electric kettle has the maximum water volume.

[0023] Beneficial effect: Since both D1 and D2 are greater than the deformation distance of the weighing sensor when the electric kettle has the maximum water volume, it can be ensured that the coupler can float up and down within the normal range.

[0024] In one alternative implementation, at least one of D1 and D2 is less than or equal to the deformation distance at the maximum load that the weighing sensor can withstand.

[0025] Beneficial effects: Since at least one of D1 and D2 is less than or equal to the deformation distance when the load cell can withstand the maximum load, the deformation distance of the deformable part will not exceed D1 or D2 when overloaded. Therefore, overload protection can be provided to prevent the load cell from failing due to deformation exceeding the deformation distance when it can withstand the maximum load.

[0026] In one optional embodiment, the upper pressure ring includes an upper pressure ring body and a fixing post protruding from the upper pressure ring body and extending downward, and the lower pressure ring is provided with a first fixing part, the fixing post being fixedly connected to the first fixing part.

[0027] Beneficial effects: The upper pressure ring includes a fixing post, which can pass through the mounting through hole of the panel structure, facilitating a fixed connection with the first fixing part of the lower pressure ring.

[0028] In one alternative embodiment, the coupler has a stepped portion on its exterior, and the upper pressure ring body abuts against the stepped portion.

[0029] Beneficial effects: The upper pressure ring body abuts against the stepped part of the coupler, and the convex rib of the lower pressure ring abuts against the bottom of the coupler. The upper and lower pressure rings cooperate to clamp the coupler in the middle, making the assembly method simple.

[0030] In one alternative embodiment, the kettle seat assembly further includes a support plate fixed to the lower side of the panel structure, the support plate having clearance holes;

[0031] The weighing sensor includes a fixed end and a deformation part. The fixed end is fixed to the support plate, and the deformation part can move along the relief hole. The deformation part is fixed to the lower pressure ring.

[0032] Beneficial effects: The deformable part of the load cell is fixed to the lower pressure ring. The deformable part of the load cell deforms as the coupler moves downward. The support plate is fixed to the lower side of the panel structure, and the fixed end of the load cell is fixed to the support plate. Therefore, the fixed end of the load cell remains stationary, while the deformable part of the load cell deforms relative to the fixed end. The deformation of the deformable part varies depending on the weight of the water in the kettle, thus allowing for accurate measurement of the water volume in the kettle. Since the weight of the kettle is directly transmitted to the load cell, it is less susceptible to external interference, thereby improving measurement accuracy.

[0033] In one optional embodiment, the pressure ring is provided with a mating part that is fixedly connected to the deformable part, and a clearance part located above the fixed end and having a gap with the fixed end.

[0034] Beneficial effects: The mating part and the deformation part are fixedly connected. When the kettle body is placed in the kettle seat assembly, the bottom of the kettle body is coupled with the coupler. Since the kettle body and the water inside the kettle body have a certain weight, they will exert downward pressure on the coupler. Since the upper pressure ring and the lower pressure ring are fixedly connected and clamp the coupler in the middle, the upper pressure ring and the lower pressure ring will move downward with the coupler and drive the deformation part of the load cell to move downward. The fixed end of the load cell remains stationary. Since there is a gap between the clearance part and the fixed end, it can be ensured that the lower pressure ring can move downward relative to the fixed end of the load cell. The deformation part of the load cell deforms relative to the fixed end, thereby achieving accurate weighing.

[0035] In one alternative embodiment, the support plate is provided with a mounting position, and the fixed end of the weighing sensor is fixed to the mounting position.

[0036] Beneficial effect: By setting the mounting position on the support plate, it is easy to position and install the weighing sensor.

[0037] In one alternative embodiment, the support plate has a surrounding rib on the side facing the coupler, the surrounding rib protruding from the surface of the support plate, and the inner side of the surrounding rib forming the mounting position.

[0038] Beneficial effect: By setting a retaining rib on the side of the support plate facing the coupler, the retaining rib protrudes from the surface of the support plate, and the fixed end of the load cell is limited and fixed inside the retaining rib. The retaining rib can limit the fixed end of the load cell and prevent the position of the load cell from moving.

[0039] In one optional embodiment, the edge of the support plate is provided with a plurality of second fixing parts, and the lower side of the panel structure is provided with a plurality of connecting posts, which are fixedly connected to the second fixing parts.

[0040] Beneficial effects: By setting multiple second fixing parts on the edge of the support plate and multiple connecting columns on the lower side of the panel structure, the connecting columns are fixedly connected to the second fixing parts, and a space sufficient to accommodate the load cell and the pressure ring is formed between the support plate and the fixing structure.

[0041] In one optional embodiment, the panel structure includes a panel and a panel support, the panel support being supported below the panel, the panel having a first through hole, and the water-blocking rib being disposed on the panel support and passing through the first through hole.

[0042] Beneficial effects: The panel structure includes a panel and a panel bracket. The panel bracket is supported below the panel, which can ensure that the upper surface of the kettle seat assembly is flat and beautiful. The water-blocking rib is set on the panel bracket and passes through the first through hole, which can prevent water from entering the installation through hole.

[0043] In one alternative implementation, the center of gravity of the coupler coincides with the force axis of the weighing sensor.

[0044] Beneficial effect: By aligning the center of gravity of the coupler with the force axis of the weighing sensor, the amount of water in the kettle can be measured more accurately.

[0045] Secondly, this utility model also provides an electric kettle, comprising:

[0046] The body of the teapot;

[0047] The kettle base assembly of the electric kettle.

[0048] Beneficial effects: This electric kettle, due to the panel structure including upward-protruding water-blocking ribs, has the function of blocking water and preventing water from entering the mounting through hole, thereby preventing water from entering the kettle base assembly through the mounting through hole and causing danger.

[0061] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0062] Related technologies include electric kettles that automatically add water based on the amount of water remaining in the kettle. The kettle's base assembly includes a weighing component. When the water level reaches a preset low level, it automatically adds water; when the water level reaches a preset high level, it automatically stops adding water. Positioning the weighing component below the coupler allows for more accurate weighing and precise control of water addition. However, because the coupler needs to float vertically, as the weight inside the kettle increases, it causes the coupler to move downwards, deforming the weighing component. Therefore, the kettle base assembly has gaps to allow the coupler to float. This allows water to enter the kettle base assembly through these gaps, potentially causing a hazard as electrical components are located inside.

[0063] The following is combined with Figures 1 to 9 The following describes embodiments of the present invention.

[0064] According to an embodiment of the present invention, in one aspect, a kettle base assembly for an electric kettle is provided, including a panel structure, the panel structure including a main body and a water-blocking rib 201 protruding upward from the main body, the inner side of the water-blocking rib 201 forming a mounting through hole 202.

[0065] In this embodiment, since the panel structure includes an upwardly protruding water-blocking rib 201, the water-blocking rib 201 has the function of blocking water and can prevent water from entering the mounting through hole 202, thereby preventing water from entering the kettle seat assembly through the mounting through hole 202 and causing danger.

[0066] In one embodiment, the kettle seat assembly further includes: a coupler 3, an upper pressure ring 4, a lower pressure ring 5, a support plate 6, and a weighing sensor 7.

[0067] The coupler 3 is floatingly mounted on the mounting through hole 202; the upper pressure ring 4 includes a surrounding edge 403 located above the panel structure and blocking the water-blocking rib 201; the lower pressure ring 5 is located on the lower side of the panel structure; the upper pressure ring 4 and the lower pressure ring 5 are fixedly connected and clamp the coupler 3 in the middle; the lower pressure ring 5 is connected to a weighing sensor 7.

[0068] In this embodiment, when the kettle body 9 is placed in the kettle base assembly, the bottom of the kettle body 9 is coupled to the coupler 3. Since the kettle body 9 and the water inside the kettle body 9 have a certain weight, they will exert downward pressure on the coupler 3. Since the upper pressure ring 4 and the lower pressure ring 5 are fixedly connected and clamp the coupler 3 in the middle, the upper pressure ring 4 and the lower pressure ring 5 will move downward together with the coupler 3. Since the lower pressure ring 5 is connected to the weighing sensor 7, it will cause the weighing sensor 7 to deform. Therefore, the amount of water in the kettle body 9 can be accurately measured. Since the weight of the kettle body 9 is directly transmitted to the weighing sensor 7, it is less affected by external interference, thus improving the accuracy of the measurement.

[0069] In addition, the upper pressure ring 4 includes a perimeter 403 located above the panel structure and covering the water-blocking rib 201. The perimeter 403 also has the function of blocking water and can prevent water from entering the kettle seat assembly through the mounting through hole 202 and causing danger.

[0070] Since the upper pressure ring 4 and the lower pressure ring 5 are fixedly connected and the coupler 3 is clamped in the middle, the assembly method of the upper pressure ring 4, the lower pressure ring 5 and the coupler 3 is simple and easy to assemble.

[0071] In one embodiment, the lower pressure ring 5 is provided with a water guide groove 501, which is connected to the mounting through hole 202.

[0072] In this embodiment, a water guide groove 501 is provided in the lower pressure ring 5. The water guide groove 501 is connected to the mounting through hole 202. Therefore, if water enters the mounting through hole 202, it will fall into the water guide groove 501, preventing water droplets from falling onto the electrical components inside the kettle seat assembly.

[0073] In one embodiment, the pressure ring 5 is further provided with a water guide pipe 502, which is connected to the water guide groove 501.

[0074] In this embodiment, by setting a water guide pipe 502, which is connected to a water guide trough 501, water falling into the water guide trough 501 will flow into the water guide pipe 502. The water is then guided to a location away from electrical components. The water guide pipe 502 and the water guide trough 501 work together to effectively prevent water from entering the kettle seat assembly and causing danger.

[0075] Specifically in one embodiment, such as Figure 2 , Figure 8 and Figure 9 As shown, the water guide channel 501 is an annular channel that can receive water entering from the mounting through hole 202 from all directions.

[0076] In one embodiment, the bottom surface of the water guide channel 501 is an inclined surface, and the water guide pipe 502 is connected to the lowest point of the water guide channel 501.

[0077] In this embodiment, since the bottom surface of the water guide trough 501 is inclined, when water falls into the water guide trough 501, it will flow down the inclined surface. The water guide pipe 502 is connected to the lowest point of the water guide trough 501, so it can be ensured that the water in the water guide trough 501 can flow to the water guide pipe 502, which can effectively prevent water from entering the kettle seat assembly and causing danger.

[0078] In one embodiment, the lower pressure ring 5 is provided with a rib 503, which abuts against the coupler 3, and the water guide groove 501 is provided on the outer periphery of the rib 503.

[0079] In this embodiment, the protruding rib 503 of the pressure ring 5 abuts against the coupler 3, which can prevent water from flowing down to the center of the pressure ring 5.

[0080] In one embodiment, the gap between the edge 403 and the panel 1 is D1, and the gap between the upper pressure ring 4 and the top of the water-blocking rib 201 is D2. Both D1 and D2 are greater than the deformation distance of the weighing sensor 7 when the electric kettle has the maximum water volume.

[0081] In this embodiment, since both D1 and D2 are greater than the deformation distance of the weighing sensor 7 when the electric kettle has the maximum water volume, it can be ensured that the coupler 3 can float up and down within the normal range.

[0082] In one embodiment, at least one of D1 and D2 is less than or equal to the deformation distance when the load cell 7 can withstand the maximum load.

[0083] In this embodiment, since at least one of D1 and D2 is less than or equal to the deformation distance of the load cell 7 when it is overloaded, the deformation distance of the deformation part 702 will not exceed D1 or D2. Therefore, overload protection can be performed to prevent the deformation of the load cell 7 from exceeding the deformation distance of its maximum load capacity and thus causing it to fail.

[0084] In one embodiment, the upper pressure ring 4 includes an upper pressure ring body 401 and a fixing post 402 that protrudes from the upper pressure ring body 401 and extends downward, and the lower pressure ring 5 is provided with a first fixing part 504, and the fixing post 402 is fixedly connected to the first fixing part 504.

[0085] In this embodiment, the upper pressure ring 4 includes a fixing post 402, which can pass through the mounting through hole 202 of the panel structure to facilitate fixed connection with the first fixing part 504 of the lower pressure ring 5.

[0086] In one specific embodiment, the fixing post 402 is provided with a threaded hole, the first fixing part 504 is a through hole, and the screw passes through the first fixing part 504 and is tightened in the fixing post 402 to achieve a fixed connection between the upper pressure ring 4 and the lower pressure ring 5.

[0087] In one embodiment, the coupler 3 is provided with a stepped portion 301, and the upper pressure ring body 401 abuts against the stepped portion 301.

[0088] In this embodiment, the upper pressure ring body 401 abuts against the stepped portion 301 of the coupler 3, and the protruding rib 503 of the lower pressure ring 5 abuts against the lower part of the coupler 3. The upper pressure ring 4 and the lower pressure ring 5 cooperate to clamp the coupler 3 in the middle, making the assembly method simple.

[0089] In one embodiment, the kettle seat assembly further includes a support plate 6, which is fixed to the lower side of the panel structure and has a clearance hole 601; the weighing sensor 7 includes a fixed end 701 and a deformation part 702, the fixed end 701 is fixed to the support plate 6, the deformation part 702 is movable along the clearance hole 601, and the deformation part 702 is fixed to the lower pressure ring 5.

[0090] In this embodiment, when the kettle body 9 is placed in the kettle base assembly, the bottom of the kettle body 9 is coupled to the coupler 3. Since the kettle body 9 and the water inside the kettle body 9 have a certain weight, they will exert downward pressure on the coupler 3. Because the upper pressure ring 4 and the lower pressure ring 5 are fixedly connected and clamp the coupler 3 in the middle, the upper pressure ring 4 and the lower pressure ring 5 will move downward together with the coupler 3. Since the deformation part 702 of the weighing sensor 7 is fixed to the lower pressure ring 5, the deformation part 702 of the weighing sensor 7 will deform as the coupler 3 moves downward. The support plate 6 is fixed to the lower side of the panel structure, and the fixed end 701 of the weighing sensor 7 is fixed to the support plate 6. Therefore, the fixed end 701 of the weighing sensor 7 remains stationary, and the deformation part 702 of the weighing sensor 7 deforms relative to the fixed end 701. The deformation of the deformation part 702 varies depending on the weight of the water in the kettle body 9. Therefore, the amount of water in the kettle body 9 can be accurately measured. Since the weight of the kettle body 9 is directly transmitted to the weighing sensor 7, it is less affected by external interference, thus improving the accuracy of the measurement.

[0091] In one embodiment, the pressure ring 5 is provided with a mating part 505 that is fixedly connected to the deformation part 702, and a clearance part 506 located above the fixed end 701 and having a gap with the fixed end 701.

[0092] In this embodiment, the mating part 505 is fixedly connected to the deformation part 702. When the kettle body 9 is placed in the kettle seat assembly, the bottom of the kettle body 9 is coupled to the coupler 3. Since the kettle body 9 and the water inside the kettle body 9 have a certain weight, they will exert downward pressure on the coupler 3. Since the upper pressure ring 4 and the lower pressure ring 5 are fixedly connected and clamp the coupler 3 in the middle, the upper pressure ring 4 and the lower pressure ring 5 will move downward together with the coupler 3, and drive the deformation part 702 of the weighing sensor 7 to move downward. The fixed end 701 of the weighing sensor 7 remains stationary. Since the clearance part 506 has a gap with the fixed end 701, it can be ensured that the lower pressure ring 5 can move downward relative to the fixed end 701 of the weighing sensor 7. The deformation part 702 of the weighing sensor 7 deforms relative to the fixed end 701, thereby achieving accurate weighing.

[0093] In one specific embodiment, the deformable part 702 is provided with a first screw hole 703, which is a blind hole. The lower pressure ring 5 is provided with a first through hole 507, and the screw passes through the first through hole 507 and is tightened in the first screw hole 703.

[0094] In one embodiment, the support plate 6 is provided with a mounting position 602, and the fixed end 701 of the weighing sensor 7 is fixed to the mounting position 602.

[0095] In this embodiment, by providing an installation position 602 on the support plate 6, it is convenient to position and install the weighing sensor 7.

[0096] In one embodiment, the support plate 6 is provided with a surrounding rib 603 on the side facing the coupler 3. The surrounding rib 603 protrudes from the surface of the support plate 6, and the inner side of the surrounding rib 603 forms a mounting position 602.

[0097] In this embodiment, a retaining rib 603 is provided on the side of the support plate 6 facing the coupler 3. The retaining rib 603 protrudes from the surface of the support plate 6. The fixed end 701 of the weighing sensor 7 is limited and fixed inside the retaining rib 603. The retaining rib 603 can limit the fixed end 701 of the weighing sensor 7 to prevent the position of the weighing sensor 7 from moving.

[0098] Specifically, such as Figure 5 As shown, the surrounding reinforcement 603 includes three reinforcement bars, namely the first reinforcement bar, the second reinforcement bar and the third reinforcement bar. The first reinforcement bar and the third reinforcement bar are parallel to each other, and the second reinforcement bar is connected between the first reinforcement bar and the third reinforcement bar. The end of the first reinforcement bar away from the second reinforcement bar and the end of the third reinforcement bar away from the second reinforcement bar are both adjacent to the clearance hole 601.

[0099] Specifically in one embodiment, such as Figure 5 As shown, the mounting position 602 is provided with a second through hole 604, and the fixing part of the load cell 7 is provided with a second screw hole 704. The second screw hole 704 is a blind hole. The second screw hole 704 extends upward from the lower surface of the load cell 7. The screw passes through the second through hole 604 from bottom to top and is tightened in the second screw hole 704.

[0100] In one embodiment, the edge of the support plate 6 is provided with a plurality of second fixing parts 605, and the lower side of the panel structure is provided with a plurality of connecting posts 203, which are fixedly connected to the second fixing parts 605.

[0101] In this embodiment, by providing multiple second fixing parts 605 on the edge of the support plate 6 and multiple connecting posts 203 on the lower side of the panel structure, the connecting posts 203 are fixedly connected to the second fixing parts 605, and a space sufficient to accommodate the weighing sensor 7 and the pressure ring 5 is formed between the support plate 6 and the fixing structure.

[0102] Specifically in one embodiment, such as Figure 5 As shown, the second fixing part 605 is a stepped hole, and the lower end of the connecting post 203 is adapted to the shape of the stepped hole.

[0103] Specifically, the connecting post 203 can be interference-fitted with the stepped hole, or it can be fixed by adhesive.

[0104] Specifically, such as Figure 5 As shown, the support plate 6 is a rectangular plate, and stepped holes are located at the four corners of the support plate 6.

[0105] In one specific embodiment, the support plate 6 is provided with a second through hole 606 through which the water pipe 502 passes.

[0106] In one embodiment, the panel structure includes a panel 1 and a panel support 2, the panel support 2 being supported below the panel 1, the panel 1 having a first through hole 101, and a water-blocking rib 201 being disposed on the panel support 2 and passing through the first through hole 101.

[0107] In this embodiment, the panel structure includes a panel 1 and a panel support 2. The panel support 2 is supported below the panel 1, which can ensure that the upper surface of the kettle seat assembly is flat and aesthetically pleasing. The water-blocking rib 201 is provided on the panel support 2 and passes through the first through hole 101, which can prevent water from entering the mounting through hole 202.

[0108] In one specific embodiment, the support plate 6 is fixedly connected to the panel bracket 2.

[0109] In one embodiment, the center line of gravity of the coupler 3 coincides with the force axis of the load cell 7.

[0110] In this embodiment, by aligning the center of gravity of the coupler 3 with the force axis of the weighing sensor 7, the amount of water in the kettle body 9 can be measured more accurately.

[0111] In one specific embodiment, the kettle base assembly further includes a base 8, which, together with the panel bracket 2, forms an installation space, and a support plate 6 is located within the installation space. The installation space also contains electrical wires, water pipes, etc.

[0112] According to an embodiment of the present invention, another aspect is provided: an electric kettle, including: a kettle body 9 and a kettle base assembly of the electric kettle provided in the above embodiment.

[0113] The electric kettle has a panel structure that includes an upwardly protruding water-blocking rib 201. The water-blocking rib 201 has the function of blocking water and can prevent water from entering the mounting through hole 202, thereby preventing water from entering the kettle base assembly through the mounting through hole 202 and causing danger.

[0114] In one embodiment, when the kettle body 9 is placed in the kettle base assembly, the bottom of the kettle body 9 is coupled to the coupler 3. Since the kettle body 9 and the water inside it have a certain weight, they exert downward pressure on the coupler 3. Because the upper pressure ring 4 and the lower pressure ring 5 are fixedly connected and clamp the coupler 3 in the middle, the upper pressure ring 4 and the lower pressure ring 5 will move downward together with the coupler 3. Since the deformation part 702 of the load cell 7 is fixed to the lower pressure ring 5, the deformation part 702 of the load cell 7 will deform as the coupler 3 moves downward. The support plate 6 is fixed to the lower side of the panel structure, and the fixed end 701 of the weighing sensor 7 is fixed to the support plate 6. Therefore, the fixed end 701 of the weighing sensor 7 remains stationary, and the deformation part 702 of the weighing sensor 7 deforms relative to the fixed end 701. The deformation of the deformation part 702 varies depending on the weight of the water in the kettle body 9. Therefore, the amount of water in the kettle body 9 can be accurately measured. Since the weight of the kettle body 9 is directly transmitted to the weighing sensor 7, it is less affected by external interference, thus improving the accuracy of the measurement.

[0115] In addition, the upper pressure ring 4 includes a perimeter 403 located above the panel structure and covering the water-blocking rib 201. The perimeter 403 also has the function of blocking water and can prevent water from entering the kettle seat assembly through the mounting through hole 202 and causing danger.

[0116] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by this application.
