[0006] The anti-leakage mechanism according to the embodiment of the utility model has at least the following beneficial effects: during the cooking process of boiling water or other cooking that requires heating in the shell, steam will be generated, and the steam can flow out from the steam outlet through the steam outlet structure in time, thereby avoiding the problem of excessive air pressure in the shell. After the boiling water is cooked, it can flow out from the water outlet through the water outlet structure, so that the boiled water can be taken.

[0007] Since the fluid in the shell cannot flow to the water outlet when the water outlet structure is not opened, the problem of leakage at the water outlet when the shell accidentally topples over can be effectively prevented. In addition, since the steam outlet structure will close the steam outlet when the shell accidentally topples over, the fluid inside the shell cannot flow out from the steam outlet when the shell accidentally topples over. Therefore, when the shell accidentally topples over, no leakage will occur at the steam outlet and the water outlet, so the situation that the contents of the shell cause harm to people outside can be effectively avoided, thereby effectively reducing the potential safety hazards that may be caused by the kettle during use.

[0008] According to some embodiments of the utility model, the water outlet structure includes an inner tank arranged in the shell, and the inner tank is used to load fluid; the inner tank is connected to a water outlet pipe, and the water outlet pipe is connected to the water outlet.

[0009] According to some embodiments of the utility model, the water outlet structure includes a control valve, which is connected to the water outlet pipe and is located between the inner tank and the water outlet, and the control valve is used to close the water outlet pipe or cancel the closing effect on the water outlet pipe.

[0012] According to some embodiments of the utility model, the movable cavity has an inner conical surface, and the outer periphery of the blocking member is provided with an outer conical surface for matching the inner conical surface, and the inner conical surface and the outer conical surface can cooperate to guide the blocking member to move toward the steam port when the shell is tilted.

[0013] According to some embodiments of the present invention, the radial dimension of the inner conical surface gradually increases toward the top of the active cavity, and the steam port is located above the active cavity.

[0014] According to some embodiments of the utility model, a steam exhaust port is opened on the side of the steam outlet component, and the steam exhaust port is connected to the active cavity; the steam exhaust port is located at the upper part of the active cavity, and the distance between the steam exhaust port and the bottom of the active cavity is greater than the height of the blocking component.

[0015] According to some embodiments of the utility model, the shell is provided with an installation groove for loading and positioning the steam outlet part, and the top of the installation groove is provided with a connecting port docking with the steam port; when the shell is tilted, the blocking part can move to block the connecting port under the action of its own weight.

[0016] The kettle according to the second aspect of the present invention comprises the anti-leakage mechanism according to the first aspect of the present invention.

[0017] The kettle according to the embodiment of the utility model has at least the following beneficial effects: during the cooking process of boiling water or other cooking that requires heating, steam will be generated in the shell, and the steam can flow out from the steam outlet through the steam outlet structure in time, thereby avoiding the problem of excessive air pressure in the shell. After the boiling water is cooked, it can flow out from the water outlet through the water outlet structure, so that the boiled water can be taken.

[0018] Since the fluid in the shell cannot flow to the water outlet when the water outlet structure is not opened, the problem of leakage at the water outlet when the shell accidentally topples over can be effectively prevented. In addition, since the steam outlet structure will close the steam outlet when the shell accidentally topples over, the fluid inside the shell cannot flow out from the steam outlet when the shell accidentally topples over. Therefore, when the shell accidentally topples over, no leakage will occur at the steam outlet and the water outlet, so the situation that the contents of the shell cause harm to people outside can be effectively avoided, thereby effectively reducing the potential safety hazards that may be caused by the kettle during use.

If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] Reference Figure 1, a leak-proof mechanism, comprising: a shell 100, a steam port 150, a water outlet structure 300 and a steam outlet structure 500; the steam port 150 is arranged in the shell 100, and the steam port 150 is connected to the shell 100; the water outlet structure 300 is arranged in the shell 100, and the shell 100 is provided with an exposed water outlet 130, and the water outlet structure 300 is connected to the water outlet 130; when and only when the water outlet structure 300 is opened, the fluid in the shell 100 can move to the water outlet 130; the steam outlet structure 500 is arranged at the steam port 150, and the steam outlet structure 500 can relatively isolate the steam port 150 and the interior of the shell 100 when the shell 100 is tilted. During the cooking process of boiling water or other cooking processes that require heating in the shell 100, steam will be generated, and the steam can flow out from the steam port 150 through the steam outlet structure 500 in time, thereby avoiding the problem of excessive air pressure in the shell 100. After the boiling water is cooked, it can flow out from the water outlet 130 through the water outlet structure 300, so that the boiled water can be taken. Since the fluid in the shell 100 cannot flow to the water outlet 130 when the water outlet structure 300 is not opened, the problem of leakage at the water outlet 130 when the shell 100 accidentally falls can be effectively prevented. In addition, since the steam outlet structure 500 will close the steam port 150 when the shell 100 falls, the fluid inside the shell 100 cannot flow out from the steam port 150 when the shell 100 accidentally falls. Therefore, when the shell 100 accidentally falls, no leakage will occur at the steam port 150 and the water outlet 130, so the content of the shell 100 can be effectively prevented from causing harm to people outside, thereby effectively reducing the potential safety hazards that may be caused by the kettle during use.

[0032] In certain embodiments, reference Figure 2 The water outlet structure 300 includes an inner liner 200 disposed in the housing 100, and the inner liner 200 is used to carry fluid; the inner liner 200 is connected to a water outlet pipe 310, and the water outlet pipe 310 is connected to the water outlet 130. The inner liner 200 can not only carry fluid, but also effectively separate the fluid carried therein from other components in the housing 100, thereby effectively preventing other electronic components in the housing 100 from being affected by the high-temperature fluid. The water outlet pipe 310 can smoothly guide the fluid in the inner liner 200 to the liquid outlet, thereby ensuring that the hot water and other fluids that have been cooked in the inner liner 200 can be smoothly taken.

[0033] Specifically, a top cover 190 is provided on the top of the inner pot 200 , and the steam port 150 is located on the top of the top cover 190 ; the steam outlet structure 500 is located at the top cover 190 and can connect or close the steam port 150 and the interior of the inner pot 200 .

[0034] It is conceivable that the housing 100 as a whole can be used to carry fluid, and components such as electronic components can be installed on the outer shell of the housing 100. The specific implementation method can be adjusted accordingly according to actual needs and is not limited here.

[0035] In certain embodiments, reference Figure 2 The water outlet structure 300 includes a control valve 320, which is connected to the water outlet pipe 310 and is located between the inner tank 200 and the water outlet 130. The control valve 320 is used to close the water outlet pipe 310 or cancel the closing effect of the water outlet pipe 310. The control valve 320 can directly and effectively control whether the water outlet pipe 310 is closed or not. Therefore, when taking the hot water or other fluid in the inner tank 200, the closing effect of the water outlet pipe 310 can be canceled by the control valve 320, so that the hot water can be smoothly taken from the water outlet 130; when the fluid in the inner tank 200 does not need to be taken, the closing effect of the water outlet pipe 310 can be maintained by the control valve 320. Therefore, even if the housing 100 is tilted in this state, the fluid in the inner tank 200 cannot flow out from the water outlet 130, so that the purpose of preventing leakage can be smoothly achieved.

[0036] In certain embodiments, reference Figure 2 The control valve 320 is a normally closed electromagnetic valve. The normally closed electromagnetic valve can not only quickly switch the state of the water outlet pipe 310 to be closed or not, but also maintain the closing effect of the water outlet pipe 310 for a long time because it is in a closed state under normal conditions, thereby maintaining the overall state of being less likely to leak.

[0037] It is conceivable that the control valve 320 may also be other types of valves, such as a ball valve. The specific implementation method may be adjusted accordingly according to actual needs and is not limited here.

[0038] In certain embodiments, reference Figure 2 The water outlet pipe 310 is connected to a fluid pump 330, and the fluid pump 330 is used to drive the fluid to flow from the inner tank 200 toward the water outlet 130. The fluid pump 330 can directly and effectively drive the fluid in the water outlet pipe 310, so that the fluid can smoothly move through the water outlet pipe 310 to the water outlet 130, thereby achieving the purpose of taking the contents in the inner tank 200.

[0039] In certain embodiments, reference Figure 3The steam outlet structure 500 includes a steam outlet member 550 disposed at the steam outlet 150, and an active cavity 559 connecting the interior of the shell 100 and the steam outlet 150 is disposed in the steam outlet member 550; a blocking member 530 is disposed in the active cavity 559, and when the shell 100 falls over, the blocking member 530 can move under the action of its own weight and block the steam outlet 150. When the fluid in the shell 100 is cooking, the high temperature during cooking will generate steam. The steam will move to the active cavity 559 in the shell 100. After that, the steam can move from the active cavity 559 to the steam outlet 150 and leave the shell 100, thereby achieving the effect of steam discharge. When the shell 100 falls over, the blocking member 530 will move close to the steam outlet 150 under the action of its own weight and block the steam outlet 150, so that the problem of high-temperature fluid leaking from the steam outlet 150 can be effectively avoided, thereby improving the overall safety performance.

[0040] It is conceivable that the steam outlet structure 500 may also be composed of other components, such as installing a stop valve at the steam port 150, and controlling the opening and closing of the stop valve to achieve the effect of steam discharge and preventing fluid leakage. The specific implementation method can be adjusted accordingly according to actual needs and is not limited here.

[0041] In certain embodiments, reference Figure 5 The active cavity 559 has an inner conical surface, and the outer circumference of the plugging member 530 is provided with an outer conical surface for matching the inner conical surface. The inner conical surface and the outer conical surface can cooperate to guide the plugging member 530 to move toward the steam port 150 when the shell 100 is tilted. After the shell 100 is tilted, the plugging member 530 will contact the inner wall of the active cavity 559, and the inner conical surface and the outer conical surface will contact each other, and an oblique force will be generated between the two. Therefore, the plugging member 530 will move toward the steam port 150 under the action of the oblique force, and successfully achieve the purpose of blocking the steam port 150 and preventing the leakage of high-temperature fluid.

[0042] Specifically, a connecting port 557 is provided at the position of the minimum radial dimension of the inner cone surface, and the connecting port 557 is connected to the outside of the active cavity 559; when the plugging member 530 closes the steam port 150, the steam port 150 and the connecting port 557 are separated by the plugging member 530. The connecting port 557 can provide air pressure for the side of the plugging member 530 away from the steam inlet, so when the air pressure changes due to the capacity change and temperature change of the high-temperature fluid in the shell 100, the connecting port 557 can timely transfer the air pressure to the active cavity 559, thereby ensuring that the plugging member 530 can smoothly move under the action of its own weight.

[0043] Specifically, the outer conical surface of the plugging member 530 gradually narrows toward the connecting port 557. As a result, the contact area between the plugging member 530 and the connecting port 557 is reduced, thereby preventing the plugging member 530 from blocking the connecting port 557. The plugging member 530 can also divide and guide the steam flowing from the connecting port 557 through its outer conical surface, thereby preventing the plugging member 530 from being pushed by the steam flowing from the connecting port 557 and accidentally blocking the steam port 150.

[0044] In certain embodiments, reference Figure 5 , the radial dimension of the inner conical surface gradually expands toward the top of the active cavity 559, and the steam port 150 is located above the active cavity 559. Since the radial dimension of the inner conical surface gradually expands toward the top, and the steam port 150 is located above the active cavity 559, after the shell 100 is tipped over, the inclination direction of the inner conical surface will be downwardly inclined toward the steam port 150, and the blocking member 530 will be subjected to an oblique force toward the steam port 150. Therefore, under the action of its own weight, the blocking member 530 will move toward the bottom of the active cavity 559, and can smoothly achieve the effect of blocking the steam port 150 located at the end of the active cavity 559, thereby automatically generating a leak-proof effect when the shell 100 is tipped over.

[0045] In certain embodiments, reference Figure 5 , a steam outlet 553 is provided on the side of the steam outlet 550, and the steam outlet 553 is connected to the active cavity 559; the steam outlet 553 is located at the upper part of the active cavity 559, and the distance between the steam outlet 553 and the bottom of the active cavity 559 is greater than the height of the blocking member 530. In the normal discharge process of steam, the steam will enter the active cavity 559 from the steam outlet 553, and move in the active cavity 559 to the steam outlet 150 at the top thereof to be discharged. In this process, the blocking member 530 will be at the bottom of the active cavity 559 under the action of its own weight. Since the height of the blocking member 530 is lower than the steam outlet 553, when the steam enters the active cavity 559, the steam will flow from the top of the blocking member 530 to the steam outlet 150 without affecting the blocking member 530, so the problem that the blocking member 530 accidentally moves in the active cavity 559 and blocks the steam outlet 150 when the steam flows can be effectively avoided.

[0046] Specifically, there are multiple exhaust ports 553 surrounding the active cavity 559 , and there is always a gap between the side of the blocking member 530 and the inner wall of the active cavity 559 , thereby ensuring that the exhaust ports 553 cannot be completely covered by the blocking member 530 .

[0047] In certain embodiments, reference Figure 4The housing 100 is provided with a mounting groove 153 for loading and positioning the steam outlet 550, and a connection port 157 for docking with the steam port 150 is provided at the top of the mounting groove 153; when the housing 100 is tilted, the blocking member 530 can move to block the connection port 157 under the action of its own weight. The mounting groove 153 can not only load the steam outlet 550, but also position the steam outlet 550 and the housing 100 relative to each other. In addition, the mounting groove 153 can also limit the movement trajectory of the steam and ensure that the steam moves smoothly and accurately in the mounting groove 153 toward the steam port 150, thereby preventing the steam from affecting other components in the housing 100.

[0048] The second aspect of the utility model provides an embodiment of a kettle, including the above-mentioned anti-leakage mechanism. During the cooking process of boiling water or other cooking that requires heating in the shell 100, steam will be generated, and the steam can flow out from the steam port 150 through the steam outlet structure 500 in time, thereby avoiding the problem of excessive air pressure in the shell 100. After the boiling water is cooked, it can flow out from the water outlet 130 through the water outlet structure 300, so as to facilitate the use of the boiling water. Since the fluid in the shell 100 cannot flow to the water outlet 130 when the water outlet structure 300 is not opened, the problem of leakage at the water outlet 130 can be effectively prevented when the shell 100 accidentally falls over. In addition, since the steam outlet structure 500 will close the steam port 150 when the shell 100 falls over, the fluid inside the shell 100 cannot flow out from the steam port 150 when the shell 100 accidentally falls over. Therefore, when the shell 100 accidentally topples over, no leakage will occur at the steam port 150 and the water outlet 130, thereby effectively preventing the contents of the shell 100 from causing harm to outsiders, thereby effectively reducing the potential safety hazards that may be caused by the kettle during use.

[0049] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0050] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
