Description

Technical Field

[0001] This utility model relates to the field of kettle technology, and in particular to a leak-proof kettle. Background Technology

[0002] Current electric kettles generally adopt the following structure: They include a kettle body and a power supply base. The power supply base supplies power to the kettle body. The kettle body has an open-topped water-holding cavity. A detachable top cover that seals the open top of the water-holding cavity is installed on the upper part of the kettle body. The lower part of the kettle body has a mounting cavity isolated from the water-holding cavity. A heating element for heating the water-holding cavity is located inside the mounting cavity. A steam delivery channel is located on the side wall of the kettle. The upper end of the steam delivery channel is connected to the water-holding cavity, and the lower end is connected to the mounting cavity. A thermostat for detecting the steam delivered to the mounting cavity by the steam delivery channel is also located inside the mounting cavity. The thermostat is connected to a control circuit board, which is electrically connected to the heating element. When the electric kettle is working, the heating element is powered on and heats the water placed inside the water chamber. When the water boils and produces steam, the steam is transported to the installation chamber through the steam delivery channel. When the thermostat detects the steam, it automatically disconnects to stop the heating element from heating. Alternatively, the thermostat feeds back information to the control circuit board, which then controls the heating element to cut off the power and stop heating.

[0003] While the electric kettle described above can meet users' needs, if the kettle body accidentally tipes over and the water in the water tank is higher than the air inlet at the top of the steam delivery channel, the water in the water tank will flow from the air inlet at the top of the steam delivery channel into the steam delivery channel and into the installation cavity. This not only wastes water but may also cause short circuits and damage to the electronic components inside the installation cavity, posing a safety hazard. Summary of the Invention

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a leak-proof kettle that helps prevent water inside the water chamber from flowing out through the steam delivery channel when the kettle is accidentally tipped over, thus improving the leak-proof performance of the kettle.

[0005] A leak-proof kettle according to an embodiment of the present invention includes a kettle body, a top lid, a waterproof and breathable membrane, a steam delivery channel, and a thermostat. The kettle body has a water-containing cavity in its upper middle part, with an open upper portion. The lower part of the kettle body has a mounting cavity, inside which is a heating element for heating the water-containing cavity. The top lid is detachably mounted on the upper part of the kettle body and can open or close the open upper portion of the water-containing cavity. An exhaust channel communicating with the water-containing cavity is provided inside the top lid. The waterproof and breathable membrane is disposed at the air inlet of the exhaust channel, or disposed inside the exhaust channel near the air inlet. The steam delivery channel includes a first steam channel and a second steam channel. The first steam channel is located on the side wall of the kettle body, and its lower part is connected to the mounting cavity. The upper part of the first steam channel extends to the upper inner wall of the water-containing cavity. The second steam channel is located inside the top cover, with one end connected to the exhaust channel and the other end extending to the outer wall of the top cover. When the top cover closes the upper opening of the water-containing cavity, the second steam channel and the first steam channel are interconnected. A thermostat is located inside the mounting cavity and is used to detect the steam delivered from the lower opening of the first steam channel.

[0006] A leak-proof kettle according to an embodiment of the present invention has at least the following beneficial effects:

[0007] This embodiment of the invention provides a leak-proof kettle by configuring the steam delivery channel as a combination of a first steam channel and a second steam channel. The second steam channel is connected to the exhaust channel of the top cover. A waterproof and breathable membrane is provided at the air inlet of the exhaust channel or near the air inlet inside the exhaust channel. Therefore, the top cover closes the opening at the top of the water-containing cavity. When the kettle is boiling water normally, the steam inside the water-containing cavity can pass through the waterproof and breathable membrane into the exhaust channel. Then, part of the steam is discharged from the air outlet of the exhaust channel, and the other part of the steam passes through the second steam channel and the first steam channel and enters the mounting cavity. The thermostat can detect the steam normally. By adopting the above structure, the normal boiling of water in the kettle is not affected. When the kettle is accidentally tilted and the water inside the water-containing cavity floods the air inlet of the exhaust channel, the water inside the water-containing cavity cannot enter the interior of the exhaust channel due to the blocking effect of the waterproof and breathable membrane, effectively preventing water from flowing out from the air outlet of the exhaust channel and preventing water from flowing from the second steam channel to the first steam channel, thereby improving the leak-proof performance of the kettle in this embodiment.

[0008] In some embodiments of this utility model, the lower part of the upper cover is provided with a filter channel communicating with the exhaust channel, the waterproof and breathable membrane is located between the exhaust channel and the filter channel, and the lower air inlet of the filter channel is provided with a filter element.

[0011] In some embodiments of this utility model, the filter element is a filter screen that can be detachably installed at the lower air inlet of the filter channel.

[0012] In some embodiments of this utility model, the upper cover is provided with a water outlet channel that can communicate with the water-containing cavity, and the upper cover is provided with a water outlet control device for controlling the opening or closing of the water outlet channel.

[0013] In some embodiments of this utility model, the upper cover has an isolation cavity that is isolated from the water outlet channel. The water outlet control device includes a connecting rod, a sealing plug, a spring, and a toggle member. The connecting rod is movably installed inside the water outlet channel, and the upper part of the connecting rod passes through the water outlet channel and extends into the isolation cavity. The sealing plug is located at the lower part of the connecting rod. The spring is located inside the isolation cavity, with one end of the spring abutting against the connecting rod and the other end abutting against the inner wall of the isolation cavity. The spring can push the connecting rod to move the sealing plug into the isolation cavity, thereby closing the water inlet of the water outlet channel. The toggle member is movably installed on the upper part of the upper cover and has a pusher located above the connecting rod. The pusher is tractively connected to the upper part of the connecting rod. When the toggle member moves the pusher relative to the upper cover, the pusher can squeeze the connecting rod to move the sealing plug downward away from the isolation cavity, thereby opening the water inlet of the water outlet channel.

[0014] In some embodiments of this utility model, the upper part of the cover is provided with a strip-shaped hole communicating with the isolation cavity, the actuating member is movably installed in the strip-shaped hole, the lower part of the pushing member is provided with a first wedge block, the upper part of the connecting rod is provided with a second wedge block that can cooperate with the first wedge block, and the first wedge block and the second wedge block abut against each other.

[0030] Reference Figures 1 to 7 and mainly refer to Figure 3 , Figure 3 , Figure 4 and Figure 5A leak-proof kettle, sometimes simply referred to as a "kettle," is provided according to certain embodiments of the present invention. The kettle includes a kettle body 100, a top cover 200, a waterproof and breathable membrane 300, a steam delivery channel, and a thermostat. A water-containing cavity 110 is provided in the upper middle part of the kettle body 100, which is used to hold water. The upper part of the water-containing cavity 110 is open. A mounting cavity 120 is provided in the lower part of the kettle body 100. The mounting cavity 120 and the water-containing cavity 110 are independently isolated from each other. A heating element 121 for heating the water-containing cavity 110 is provided inside the mounting cavity 120. In this embodiment, the heating element 121 is a resistance heating wire that can generate heat when energized. The top cover 200 is detachably installed on the upper part of the kettle body 100. The top cover 200 can open or close the upper opening of the water-containing cavity 110. The top cover 200 has an exhaust channel 210 connected to the water-containing cavity 110. When the heating element 121 heats the water-containing cavity 110 and causes the water to boil and generate steam, the steam can pass through the exhaust channel 210 and be discharged to the outside of the kettle body 100, effectively preventing excessive air pressure inside the water-containing cavity 110. A waterproof and breathable membrane 300 is disposed at the air inlet of the exhaust channel 210, or the waterproof and breathable membrane 300 is disposed inside the exhaust channel 210 near the air inlet. The waterproof and breathable membrane 300 has the characteristic of allowing gas to pass through the membrane but not water. Since the waterproof and breathable membrane 300 is known technology in the art, it will not be described in detail here. The steam delivery channel includes a first steam channel 410 and a second steam channel 420. The first steam channel 410 is located on the side wall of the kettle body 100. The lower part of the first steam channel 410 is connected to the mounting cavity 120, and the upper part of the first steam channel 410 extends to the upper inner wall of the water-containing cavity 110. The second steam channel 420 is located inside the upper cover 200. One end of the second steam channel 420 is connected to the exhaust channel 210, and the other end of the second steam channel 420 extends to the outer side wall of the upper cover 200. When the upper cover 200 closes the upper opening of the water-containing cavity 110, the second steam channel 420 and the first steam channel 410 are interconnected. Specifically, after the upper cover 200 is installed on the upper part of the kettle body 100, the opening of the second steam channel 420 on the outer side wall of the upper cover 200 is aligned with the opening of the first steam channel 410 on the upper inner wall of the water-containing cavity 110. At this time, the second steam channel 420 and the first steam channel 410 are interconnected to form a steam delivery channel. The thermostat is located inside the mounting cavity 120 and is used to detect the steam delivered from the lower opening of the first steam channel 410.

[0031] This utility model provides a leak-proof kettle by configuring a steam delivery channel consisting of a first steam channel 410 and a second steam channel 420. The second steam channel 420 connects to the exhaust channel 210 of the upper cover 200. A waterproof and breathable membrane 300 is provided at the air inlet of the exhaust channel 210 or near the air inlet inside the exhaust channel 210. Therefore, the upper cover 200 closes the opening at the top of the water-containing cavity 110. When the kettle is boiling water normally, the steam inside the water-containing cavity 110 can pass through the waterproof and breathable membrane 300 and enter the exhaust channel 210. Then, part of the steam is discharged from the air outlet of the exhaust channel 210, and the other part of the steam passes through the first steam channel 410 and the second steam channel 420. The second steam channel 420 and the first steam channel 410 enter the mounting cavity 120. The thermostat inside the mounting cavity 120 can detect steam normally. By adopting the above structure, the normal boiling of water in the kettle is not affected. When the kettle is accidentally tilted and the water in the water-containing cavity 110 floods the air inlet of the exhaust channel 210, the water in the water-containing cavity 110 cannot enter the interior of the exhaust channel 210 due to the blocking effect of the waterproof and breathable membrane 300. This effectively prevents water from flowing out of the air outlet of the exhaust channel 210 and also prevents water from flowing from the second steam channel 420 to the first steam channel 410, thereby improving the leak-proof performance of the kettle in this embodiment.

[0032] Reference Figure 3 and Figure 4 In some embodiments of this invention, to prevent food from adhering to the surface of the waterproof and breathable membrane 300 and affecting its breathability when the user cooks with a kettle, a filter channel 220 connected to the exhaust channel 210 is provided at the lower part of the top cover 200. The waterproof and breathable membrane 300 is located between the exhaust channel 210 and the filter channel 220, and a filter element 221 is provided at the lower air inlet of the filter channel 220. In some embodiments of this invention, the filter element 221 and the top cover 200 are an integral structure. Specifically, the filter element 221 is part of the lower surface of the top cover 200, and a plurality of filter holes 222 are spaced apart on the surface of the filter element 221. By adopting the above structure, the filter element 221 can filter and isolate some large food particles, preventing food from adhering to the surface of the waterproof and breathable membrane 300 and greatly reducing the breathability of the waterproof and breathable membrane 300. It also makes it convenient for the user to clean the top cover 200 afterward.

[0033] In some embodiments of this utility model, the filter element 221 and the top cover 200 can be configured as separate structures. Specifically, the filter element 221 is a filter screen that can be detachably installed at the lower air inlet of the filter channel 220. By using a filter screen to filter large food particles, the purpose of filtering food is also achieved, preventing food from adhering to the surface of the waterproof and breathable membrane 300 and thus reducing the breathability of the waterproof and breathable membrane 300. The specific configuration can be determined according to actual needs.

[0034] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 To allow users to empty the water chamber 110 without removing the top cover 200, in some embodiments of this invention, the top cover 200 is provided with a water outlet channel 230 that communicates with the water chamber 110. The top cover 200 is also equipped with a water outlet control device to control the opening and closing of the water outlet channel 230. When the user needs to use the water in the water chamber 110, the user only needs to open the water outlet channel 230 through the water outlet control device. At this time, the user can tilt the kettle body 100, and the water in the water chamber 110 can flow out from the water outlet channel 230, making it convenient for the user to use water. When the user does not need to use water, the user only needs to close the water outlet channel 230 through the water outlet control device to prevent the water in the water chamber 110 from flowing out, thus achieving the function of preventing leakage.

[0035] In some embodiments of this utility model, the upper cover 200 has an isolation cavity 240 that is isolated from the water outlet channel 230. The water outlet control device includes a connecting rod 510, a sealing plug 520, a spring 530, and a toggle member 540. The connecting rod 510 is movably installed inside the water outlet channel 230, and the upper part of the connecting rod 510 passes through the water outlet channel 230 and extends into the interior of the isolation cavity 240. The upper part of the connecting rod 510 is sealed to the water outlet channel 230, so water inside the water outlet channel 230 cannot pass through the gap between the water outlet channel 230 and the connecting rod 510 to enter the isolation cavity 240. A sealing plug 520 is located at the lower part of the connecting rod 510. A spring 530 is located inside the isolation cavity 240. One end of the spring 530 abuts against the connecting rod 510, and the other end abuts against the inner wall of the isolation cavity 240. The spring 530 can push the connecting rod 510 to move the sealing plug 520 into the isolation cavity 240, thereby closing the inlet of the water outlet channel 230. An actuating member 540 is movably mounted on the upper part of the upper cover 200, and the actuating member 540 has a pushing member 541 located above the connecting rod 510. The pushing member 541 is drively connected to the upper part of the connecting rod 510. Figure 7 As shown, when the actuating member 540 drives the pushing member 541 to move relative to the upper cover 200, the pushing member 541 can press the connecting rod 510, causing the sealing plug 520 to move downward away from the isolation chamber 240. The connecting rod 510 compresses the spring 530, causing it to contract and deform, and the sealing plug 520 opens the inlet of the water outlet channel 230. Figure 6As shown, when the user needs to close the water outlet channel 230 through the water outlet control device, the user only needs to push the toggle member 540 to drive the push member 541 to move in the opposite direction relative to the upper cover 200. At this time, the push member 541 no longer squeezes the connecting rod 510, the spring 530 restores its deformation and pushes the connecting rod 510 to drive the sealing plug 520 to move into the isolation chamber 240, so that the sealing plug 520 closes the water inlet of the water outlet channel 230. The operation is simple and quick.

[0036] In some embodiments of this utility model, the upper part of the cover 200 has a strip-shaped hole 250 communicating with the isolation cavity 240. The actuating member 540 is movably installed in the strip-shaped hole 250. The lower part of the pushing member 541 is provided with a first wedge block 542, and the upper part of the connecting rod 510 is provided with a second wedge block 511 that can cooperate with the first wedge block 542. The first wedge block 542 and the second wedge block 511 abut against each other. By adopting the above structure, the pushing member 541 can better squeeze the connecting rod 510 to drive the sealing plug 520 to move downward and open the water outlet channel 230.

[0037] Reference Figure 1 and Figure 2 To ensure that the top cover 200 can be securely installed on the upper part of the kettle body 100, in some embodiments of this invention, one or more snap-fit ​​structures are provided between the outer wall of the top cover 200 and the inner wall of the water-containing cavity 110. The snap-fit ​​structure includes a snap-fit ​​block 610 and a snap-fit ​​groove 620 that can engage with each other. One of the snap-fit ​​block 610 and the snap-fit ​​groove 620 is located on the outer wall of the top cover 200, and the other is located on the inner wall of the water-containing cavity 110. Specifically, when the snap-fit ​​block 610 is located on the inner wall of the water-containing cavity 110, the snap-fit ​​groove 620 is located on the outer wall of the top cover 200; or when the snap-fit ​​block 610 is located on the outer wall of the top cover 200, the snap-fit ​​groove 620 is located on the inner wall of the water-containing cavity 110. The top cover 200 is installed on the upper part of the kettle body 100. When the top cover 200 rotates relative to the kettle body 100, the locking block 610 can be screwed into the locking groove 620. Alternatively, when the top cover 200 rotates in the opposite direction relative to the kettle body 100, the locking block 610 can be screwed out from inside the locking groove 620. Through the engagement of the locking block 610 and the locking groove 620, the top cover 200 can be securely installed on the upper part of the kettle body 100. This securely seals the opening at the top of the water-containing cavity 110, preventing the top cover 200 from accidentally detaching from the upper part of the kettle body 100 and causing water leakage from the water-containing cavity 110. This greatly improves the leak-proof performance of the kettle in this embodiment.

[0038] To facilitate the user's operation of rotating the top cover 200 relative to the kettle body 100 in either the forward or reverse direction, in some embodiments of this utility model, a rotating handle 260 is provided on the outer side wall of the top cover 200. Therefore, when the user closes the top cover 200 onto the opening at the top of the water-containing cavity 110, the user can hold the rotating handle 260 and drive the top cover 20 to rotate in either the forward or reverse direction relative to the kettle body 100, making the operation more convenient.

[0039] Reference Figures 1 to 3 To facilitate power supply to the kettle body 100, some embodiments of this utility model of a leak-proof kettle also include a power supply base 600. A coupling capable of cooperating to supply power is provided between the power supply base 600 and the kettle body 100. Therefore, when the user places the kettle body 100 on the power supply base 600, the power supply base 600 can supply power to the kettle body 100, making operation simple and convenient.

[0040] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
