Description

[Technical Field]

[0001] The present invention relates to the technical field of household appliances, and in particular to liquid heating vessels. [Background technology]

[0002] Currently, existing electric kettles are designed with a tip-over prevention mechanism to prevent water from spilling when the kettle is tipped over. Most conventional tip-over prevention mechanisms use steel balls inside the kettle cover to seal the kettle when it is tipped over. However, the steel balls move during use, which generates strange noises and makes the kettle uncomfortable to use. Summary of the Invention [Problem to be solved by the invention]

[0003] The present invention aims to solve at least the problem of abnormal noise caused by rolling steel balls inside the cover of an anti-tip kettle that exists in the above-mentioned prior art or related art. [Means for solving the problem]

[0004] To this end, a first aspect of the present invention provides a liquid heating vessel.

[0005] According to one aspect of the present invention, there is provided a liquid heating container, the liquid heating container comprising: a kettle body having a kettle mouth at an upper portion of the kettle body; a kettle cover for covering and sealing the kettle mouth, the kettle cover having a steam accommodating cavity, the kettle cover having a steam inlet for communicating the interior of the kettle body with the steam accommodating cavity and a steam outlet for communicating the steam accommodating cavity with the outside; and an air guide passage, a first end of the air guide passage communicating with the steam outlet and a second end of the air guide passage extending toward the bottom of the kettle body and communicating with the outside.

[0006] The liquid heating container proposed in this embodiment does not have steel balls, compared to conventional anti-tip covers that use steel balls to block the steam inlet, so the kettle cover is safer, makes no noise, and is comfortable to use.

[0007] Furthermore, according to one aspect of the present disclosure, the air guide passage is connected to the steam accommodating cavity inside the kettle cover, so that the steam inside the kettle body is buffered in the steam accommodating cavity and then discharged to the outside through the air guide passage, maintaining the pressure balance inside and outside the kettle and preventing the liquid inside the kettle body from leaking out through the air guide passage, thereby preventing the liquid from spilling when the liquid heating container is tipped over.

[0008] In some embodiments, the vapor-accommodating cavity is provided with at least one buffer chamber, the buffer chamber communicates with the vapor-accommodating cavity, and the steam inlet communicates with the interior of the kettle body through the buffer chamber, thereby connecting the interior of the kettle body with the vapor-accommodating cavity. Therefore, the buffer structure further includes a buffer chamber, which provides a longer buffer time for the release of water and gas, making it difficult for the water and gas to mix. Since the flow rate of the gas under high pressure is faster than the flow rate of the liquid, the gas can be expelled to the outside, achieving pressure balance between the inside and outside of the kettle and preventing the liquid from overflowing.

[0009] In some embodiments, the buffer chamber includes a first buffer chamber and a second buffer chamber, the steam inlet is provided in the first buffer chamber, and the second buffer chamber is in communication with the first buffer chamber and the steam accommodating cavity. The air pressure in the kettle body is completely released through the multi-buffer system, reducing the internal pressure and forcing water out of the kettle body.

[0010] In some embodiments, the outer diameter of the kettle body increases from its upper end to its lower end, and the second end of the air guide passage is higher than the first end of the air guide passage when the kettle body is overturned. By making the second end of the air guide passage higher than the first end of the air guide passage, the risk of liquid spilling can be further avoided.

[0011] In some embodiments, the kettle cover comprises an intermediate cover and a lower cover positioned below the intermediate cover, the intermediate cover and the lower cover being connected to each other and enclosing and forming a steam-containing cavity.

[0012] In some embodiments, the kettle cover includes an intermediate cover and a lower cover located below the intermediate cover, with a downwardly protruding upper fence attached to the lower surface of the intermediate cover and / or an upwardly protruding lower fence attached to the upper surface of the lower cover, the intermediate cover and the lower cover being connected to each other to enclose and form a steam-accommodating cavity, and the upper fence and / or the lower fence enclose and form a buffer chamber. By providing the upper fence and / or the lower fence, the steam-accommodating cavity and the buffer cavity can be formed simultaneously when connecting the intermediate cover and the lower cover, simplifying the installation process.

[0013] In some embodiments, the kettle cover includes an intermediate cover and a lower cover located below the intermediate cover, with a first fence on the underside of the intermediate cover and a second fence on the upper surface of the lower cover, and when the intermediate cover and the lower cover are connected to each other, the first fence and the second fence surround and form a first buffer chamber. By arranging the upper fence on the underside of the intermediate cover and the lower fence on the upper surface of the lower cover, it is easy to manufacture and form the first buffer chamber and to abut against each other and then seal and engage with each other.

[0014] In some embodiments, a third fence is provided on the underside of the middle cover, a fourth fence is provided on the upper surface of the lower cover, and when the middle cover and the lower cover are connected to each other, the third and fourth fences surround and form a second buffer chamber, a first vent hole is provided in a side wall of the first fence and / or the second fence, a second vent hole and a third vent hole are provided in a side wall of the third fence and / or the fourth fence, the second vent hole communicates with the first vent hole, and the third vent hole communicates with the vapor accommodating cavity. By providing vent holes in the side walls of the first buffer chamber and the second buffer chamber, respectively, and abutting both ends of the vent holes, the first buffer chamber and the second buffer chamber can easily communicate with each other, resulting in a simple structure and easy manufacturing.

[0015] In some embodiments, an upper fence protruding downward is provided on the lower surface of the intermediate cover, and a lower fence protruding upward is provided on the upper surface of the lower cover, the upper and lower fences are formed in an annular shape, the upper fence is formed integrally with the intermediate cover, the lower fence is formed integrally with the lower cover, a first inclined surface is provided at the lower end of the upper fence, and a second inclined surface is provided at the upper end of the lower fence, and the intermediate and lower covers are connected to each other because the first inclined surface and the second inclined surface abut against each other and are interference-fitted. Because the upper fence is formed integrally with the intermediate cover and the lower fence is formed integrally with the lower cover, and the two inclined surfaces are interference-fitted, the buffer chamber can be sealed, and the structure is simple and assembly is easy.

[0016] In some embodiments, the steam inlet is provided on the bottom wall of the kettle cover and is located in the first buffer chamber, the number of first buffer chambers is at least two, the number of steam inlets corresponds to the number of first buffer chambers and is at least two, and the number of second buffer chambers is at least 1. By arranging two first buffer chambers and two steam inlets, it can be ensured that when one of the steam inlets is blocked by liquid, steam can enter the steam buffer chamber through the other steam inlet and be discharged to the outside through the air guide passage.

[0017] In some embodiments, the liquid heating container further comprises a spout and a handle arranged opposite each other, the number of steam inlets is two, the two steam inlets are arranged symmetrically with respect to a line connecting the spout and the handle, the steam inlet is located on one side of the kettle cover adjacent to the spout, the number of second buffer chambers is one, the second buffer chamber is located adjacent to one side of the handle, and the air guide passage is located on that side where the handle is located.

[0018] In these embodiments, the handle is generally used as a fulcrum when pouring into the liquid heating container, and the two steam inlets are arranged symmetrically with respect to the line connecting the spout and the handle, so that no matter which way the liquid heating container is tilted, the steam inlet at the top end is not covered with liquid and remains in a conductive state, allowing steam to quickly flow out through at least one steam inlet, buffer chamber, steam accommodating cavity, and air guide passage, preventing the risk of excessive pressure due to steam not being able to be released within the kettle body and meeting the need to prevent the liquid heating container from tipping over.

[0019] In some embodiments, the liquid heating container further includes a kettle bottom lid installed under the kettle body and a thermostat installed on the kettle bottom lid, the second end of the air guide passage extends into the kettle bottom lid, and the second end of the air guide passage faces the thermostat. In these embodiments, the air outlet end of the air guide passage faces the thermostat, and the thermostat can timely detect the temperature of the steam discharged from the air guide passage and thereby immediately cut off the circuit if the temperature is too high, thereby improving safety.

[0020] In some embodiments, a pressure reduction hole is provided in the bottom wall of the kettle cover, the pressure reduction hole connects the steam accommodating cavity to the kettle body, the pressure reduction hole is located outside the buffer chamber, and the size of the pressure reduction hole is smaller than the size of the steam inlet.

[0021] In these embodiments, the size of the pressure reduction hole is smaller than the size of the steam inlet, allowing a large amount of steam to enter the steam pressure reduction chamber through the steam inlet, where it is buffered and then discharged to the outside through the air guide passage. Furthermore, the pressure reduction hole can reduce pressure. For example, when a user lifts the kettle body to pour water, multiple steam inlets may be blocked by liquid. In this situation, the pressure in the kettle body is released through the pressure reduction hole, avoiding the risk of excessive pressure inside the kettle body. Furthermore, the pressure reduction hole and the air guide passage are connected to the outside, maintaining a pressure balance between the inside and outside of the kettle body and favoring the pouring of water outside. Furthermore, the pressure reduction hole functions as a circulation hole, allowing liquid inside the kettle cover to circulate back into the kettle body through the pressure reduction hole.

[0022] In some embodiments, the liquid heating vessel further includes a first sealing ring installed at the connection between the lower cover and the intermediate cover to seal the gap between the lower cover and the intermediate cover, the first sealing ring sealing the gap between the kettle cover and the kettle body. In these embodiments, the first sealing ring that can seal the gap between the lower cover and the intermediate cover is installed at the connection between the lower cover and the intermediate cover, and can improve the sealing performance of the steam accommodating cavity.

[0023] In some embodiments, after the intermediate cover is connected to the lower cover, a locking groove is formed between the lower cover and the intermediate cover, and the first sealing ring includes a rib that fits into the locking groove and snaps into it. In these embodiments, the rib of the first sealing ring is clamped into the locking groove formed between the lower cover and the intermediate cover, facilitating secure installation of the first sealing ring. The first sealing ring covers the joint between the lower cover and the intermediate cover, achieving a seal. Furthermore, the first sealing ring simultaneously achieves a seal between the kettle cover and the kettle spout, achieving a seal between two components with one component, improving component utilization.

[0024] In some embodiments, the air guide passage is located in the kettle body, or the kettle body is connected to the handle and the air guide passage is installed in the handle. By providing the air guide passage in the kettle body or the handle, the air guide passage can be hidden from the outside, improving the aesthetics of the product.

[0025] In some embodiments, the kettle body is connected to a handle, a first end of the handle includes a hollow portion, the hollow portion communicates with the steam accommodating cavity through a steam outlet, a first end of the air guide passage is located in the hollow portion, a through hole is provided in the bottom wall of the hollow portion, and a second end of the air guide passage extends through the through hole to the bottom of the kettle body and to the outside of the kettle body.

[0026] In these embodiments, the air guide passage extends into the kettle body through a hollow portion of the handle and a through-hole in the bottom wall of the handle, allowing the air guide passage to be hidden within the kettle body and improving the aesthetic appearance of the liquid heating container.The second end of the air guide passage passes through the bottom wall of the kettle body and is inserted into the kettle bottom lid, extending to the thermostat, which can control the on / off of the heater according to the steam temperature, preventing the liquid heating container from burning out and improving use safety.

[0038] Hereinafter, an embodiment of a liquid heating container of the present invention will be described with reference to FIGS.

[0039] As shown in Figures 1, 2, 3, 4, and 5, a first embodiment of the present invention provides a liquid heating container, which includes a kettle body 10, a kettle cover 20, and an air guide passage 30. The kettle body 10 has a kettle mouth 110 at its top, and the outer diameter of the kettle body 10 gradually increases from its upper end to its lower end. The kettle cover 20 covers and seals the kettle mouth 110, and a steam accommodating cavity is provided in the kettle cover 20, which communicates with the interior cavity of the kettle body 10. The air guide passage 30 is provided in the kettle body 10, and a first end of the air guide passage 30 communicates with the steam accommodating cavity and a second end of the air guide passage 30 extends to the bottom of the kettle body 10 and communicates with the outside. When the kettle body 10 is overturned, the first end of the air guide passage 30 is lower than the second end of the air guide passage 30.

[0040] The liquid heating container proposed in this embodiment comprises a kettle body 10, a kettle cover 20, and an air guide passage 30. The kettle cover 20 covers and seals the kettle mouth 110, so that when the liquid heating container is tipped over, the liquid in the kettle body 10 will not spill directly from the kettle mouth 110. Furthermore, the air guide passage 30 communicates with the steam accommodating cavity in the kettle cover 20, allowing steam in the kettle body 10 to be discharged to the outside through the steam accommodating cavity and the air guide passage 30, thereby achieving normal pressure release and ventilation. Furthermore, the assembly of the kettle cover 20 and the kettle body 10 forms an anti-tip kettle, and the pressure inside and outside the kettle is balanced due to the difference in flow speed between the steam and water inside the kettle cover 20. Under high pressure, the flow rate of steam is greater than the flow rate of water, so that when the liquid heating container is overturned, the steam enters the air guide passage 30 before the liquid and is discharged to the outside, thereby achieving a pressure balance between the inside and outside of the kettle body, preventing the liquid in the kettle body from leaking out, and preventing the liquid from overflowing when the liquid heating container is overturned.

[0041] Furthermore, because the kettle body 10 has a small upper portion and a large lower portion, when the liquid heating container is tipped over, it is easy to ensure that the second end of the air guide passage 30, which communicates with the outside, is higher than the first end connected to the steam accommodating cavity. Because a pressure balance is achieved between the inside and outside of the liquid heating container, even if there is liquid in the air guide passage 30, the liquid will not flow to the second end of the air guide passage 30. This prevents the liquid in the kettle body 10 from leaking out through the air guide passage 30 and prevents the liquid from spilling when the liquid heating container is tipped over.

[0042] Furthermore, the liquid heating container proposed in this embodiment does not have steel balls, compared to conventional anti-tip kettle covers that block the steam inlet with steel balls, so the kettle cover 20 is safer, makes no strange noises, and is comfortable to use.

[0043] According to one embodiment, the steam-accommodating cavity is provided with at least one buffer chamber, which communicates with the steam-accommodating cavity. The kettle cover 20 is provided with a steam inlet for communicating the interior of the kettle body 10 with the steam-accommodating cavity and a steam outlet for communicating the steam-accommodating cavity with the outside. A first end of the air guide passage 30 communicates with the steam outlet, thereby connecting the steam-accommodating cavity with the outside. Steam inside the kettle body 10 first enters the buffer chamber through the steam inlet 221, then enters the steam-accommodating cavity, and then enters the air guide passage 30 through the steam outlet. The multiple buffers in the buffer chamber and the steam-accommodating cavity promote separation of the steam and liquid, allowing the steam to enter the steam-accommodating cavity before the liquid and then to be discharged to the outside through the air guide passage 30. This quickly achieves pressure balance between the inside and outside of the kettle body 10 and prevents the liquid from leaking out.

[0044] According to one aspect of the embodiment, there may be at least one buffer cavity, or multiple buffer cavities, thereby achieving a multi-level buffering effect. The buffer chambers include a first buffer chamber 230 and a second buffer chamber 240. The first buffer chamber 230 is provided with a steam inlet 221, and the second buffer chamber 240 communicates with the first buffer chamber 230 and the steam-accommodating cavity. Steam within the kettle body 10 enters the first buffer chamber 230 through the steam inlet 221, passes through the second buffer chamber 240 and the steam-accommodating cavity, and is finally discharged to the outside through the air guide passage 30. The multiple buffers of the buffer chambers and the steam-accommodating cavity promote separation of the steam and liquid, allowing the steam to enter the steam-accommodating cavity before the liquid and be discharged to the outside through the air guide passage 30.

[0045] The kettle cover 20 includes an intermediate cover 210 and a lower cover 220 positioned below the intermediate cover 210. An upper fence protruding downward is provided on the lower surface of the intermediate cover 210, and / or a lower fence protruding upward is provided on the upper surface of the lower cover 220. The intermediate cover 210 and the lower cover 220 are connected to each other to enclose a steam-containing cavity, and the upper fence and / or the lower fence enclose at least one buffer chamber, such as a first buffer chamber 230 and a second buffer chamber 240. For example, the upper fence can be formed integrally with the intermediate cover 210 or formed as two separate pieces that are then connected to each other. The lower fence can be formed integrally with the lower cover 220 or formed as two separate pieces that are then connected to each other. The integrated structure simplifies subsequent installation processes. According to one embodiment of the present invention, only the upper housing may be formed, and the upper fence may abut against the upper surface of the lower cover 220 to form a buffer chamber; only the lower fence may be formed, and the lower fence may abut against the lower surface of the middle cover 210 to form a buffer chamber; or both the upper and lower fences may be formed simultaneously, and the upper fence may abut against the lower fence to form a buffer chamber. A more detailed description will be provided below in conjunction with the accompanying drawings.

[0046] As shown in Figures 4, 7, 8, 9 and 13, in some embodiments, kettle cover 20 includes intermediate cover 210 and lower cover 220, intermediate cover 210 is connected to lower cover 220 and together with lower cover 220 encloses and forms a steam accommodating cavity, and lower cover 220 is provided with at least two steam inlets 221 penetrating lower cover 220. At least two first buffer chambers 230 are provided within the steam accommodating cavity, and lower cover 220 is provided with steam inlets 221 at positions corresponding to first buffer chambers 230.

[0047] In these embodiments, the middle cover 210 and the lower cover 220 surround and form a steam-accommodating cavity, and at least two first buffer chambers 230 are disposed in the steam-accommodating cavity, and the first buffer chambers 230 correspond to and communicate with the steam inlets 221 disposed in the lower cover 220. The steam in the kettle body 10 first enters the first buffer chambers 230 through the steam inlets 221, where it is buffered and slowed down, and then discharges into the steam-accommodating cavity for further buffering and pressure relief, before being discharged through the steam outlet into the air guiding passage 30, thereby preventing excessive pressure in the kettle cover 20 from flowing directly into the air guiding passage 30 and allowing the steam to be discharged more gently. Similarly, if the liquid heating container is overturned, the liquid in the kettle body 10 first enters the first buffer chambers 230 through the steam inlets 221 and then discharges into the steam-accommodating cavity. The first buffer chamber 230 can play a role in shock absorption, and when the liquid heating container is overturned, the liquid flows into the steam receiving cavity and then directly into the air guide passage 30, preventing the liquid from flowing out of the kettle body 10 through the air guide passage 30 due to the liquid flow rate being too fast.

[0048] 4, 7, 8 and 9, the upper fence comprises a first fence 211 mounted on the underside of the intermediate cover 210, and the lower fence comprises a second fence 222 mounted on the upper surface of the lower cover 220, and when the intermediate cover 210 and the lower cover 220 are connected to each other, the first fence 211 and the second fence 222 surround and form a first buffer chamber 230. This arrangement has a simple structure and is advantageous for processing and manufacturing the kettle cover 20.

[0049] As shown in Figures 8, 9 and 12, in some embodiments, a first inclined surface 212 is provided at the lower end of the first fence 211, and a second inclined surface 223 is provided at the upper end of the second fence 222, and the first inclined surface 212 and the second inclined surface 223 abut against each other and are tightly fitted together.

[0050] In these embodiments, the contact surfaces where the first fence 211 and the second fence 222 abut against each other are both inclined surfaces. When the middle cover 210 and the lower cover 220 are fastened together with fasteners, the first inclined surface 212 and the second inclined surface 223 are tightly fitted together, causing slight plastic deformation, ensuring a sealed connection with the first buffer chamber 230 and improving the sealing of the first buffer chamber 230.

[0051] 8 , 9 , 10 , 11 , and 12 , a first fixed post 270 is provided in the center of the area surrounded by the first fence 211, and a second fixed post 271 is provided in the center of the area surrounded by the second fence 222. The first fixed post 270 and the second fixed post 271 are inserted into or abut against each other and connected with fasteners 272 (e.g., screws) to achieve a fastening connection between the first fence 211 and the second fence 222, and slight plastic deformation occurs in the first fence 211 and the second fence 222, thereby tightly sealing the first buffer chamber 230 in the attached position.

[0052] In some embodiments, the first vent hole is provided on a side wall of the first fence 211 and / or the second fence 222. As shown in Figures 4, 7, 8, and 9, the upper fence further includes a third fence 213 provided on the underside of the middle cover 210, and the lower fence further includes a fourth fence 224 provided on the upper side of the lower cover 220. When the middle cover 210 and the lower cover 220 are connected to each other, the third fence 213 and the fourth fence 224 surround and form the second buffer chamber 240. The first vent hole is provided on a side wall of the first fence 211 and / or the second fence 222, and the second vent hole and the third vent hole are provided on a side wall of the third fence 213 and / or the fourth fence 224, with the second vent hole communicating with the first vent hole and the third vent hole communicating with the steam accommodating cavity.

[0053] In these embodiments, the first buffer chamber 230 and the second buffer chamber 240 are connected via first and second vent holes provided in the side walls, and the cooperation between the second buffer chamber 240 and the first buffer chamber 230 can serve as a double shock absorber. Steam or liquid in the kettle body 10 first enters the first buffer chamber 230 through the steam inlet 221, then flows into the second buffer chamber 240, and then is discharged into the steam accommodating cavity, thereby improving the effect of preventing liquid from spilling when the liquid heating container is tipped over.

[0054] 8, 9, and 12, in some embodiments, the lower end of the third fence 213 is provided with a third inclined surface 2131, and the upper end of the fourth fence is provided with a fourth inclined surface 2241. The third inclined surface 2131 abuts against the fourth inclined surface 2241 for a tight fit. With this arrangement, the contact surfaces of the third fence 213 and the fourth fence 224 are both inclined surfaces, and the third inclined surface 2131 and the fourth inclined surface 2241 are tightly fitted together, causing slight plastic deformation, which ensures a sealed connection with the second buffer chamber 240 and improves the sealing of the second buffer chamber 240.

[0055] 8 , 9 , 10 , 11 and 12 , in some embodiments, a third fixed post 280 is provided in the center of the area surrounded by the third fence 213, and a fourth fixed post 281 is provided in the center of the area surrounded by the fourth fence 224. The third fixed post 280 and the fourth fixed post 281 are inserted into or abut against each other and connected by fasteners 272 (e.g., screws), achieving a fastening connection between the third fence 213 and the fourth fence 224, which causes slight plastic deformation of the third fence 213 and the fourth fence 224, and the second buffer chamber 240 is tightly and sealed in the installed position.

[0056] In some embodiments, as shown in Figures 7, 8, 9, 10, 11 and 12, the liquid heating container further includes a first sealing ring 40, which is installed at the junction between lower cover 220 and intermediate cover 210 to seal the gap between lower cover 220 and intermediate cover 210, thereby improving the sealing performance of the steam-accommodating cavity. First sealing ring 40 can also seal the gap between kettle cover 20 and kettle body 10.

[0057] In some embodiments, as shown in Figures 7, 8, 9, 10, 11 and 12, after the middle cover 210 is connected to the lower cover 220, a locking groove 250 is formed between the lower cover 220 and the middle cover 210, and the first sealing ring 40 includes a rib 410 that fits into the locking groove 250, and the rib 410 is snap-engaged into the locking groove 250.

[0058] In some embodiments, the rib 410 of the first sealing ring 40 is engaged in the engagement groove 250 formed between the lower cover 220 and the middle cover 210, facilitating the fixed installation of the first sealing ring 40. The first sealing ring 40 covers the joint between the lower cover 220 and the middle cover 210 to achieve a seal. Furthermore, the first sealing ring 40 also simultaneously achieves a seal between the kettle cover 20 and the kettle opening 110, thereby achieving a seal between two components with one component and improving component utilization.

[0059] Specifically, the middle cover 210 is connected to the lower cover 220 to form a vapor-accommodating cavity, and after the middle cover 210 and the lower cover 220 are assembled, a locking groove 250 is formed around the outer wall. The inner wall of the first sealing ring 40 is provided with a rib 410, which is fitted into the locking groove 250, and the gap between the lower cover 220 and the middle cover 210 is filled by the rib 410 of the first sealing ring 40, thereby achieving sealing.

[0060] In some embodiments, as shown in Figures 1, 2, 4, 5 and 6, the liquid heating container further includes a spout 140 and a handle 150 arranged opposite each other, the number of steam inlets 221 is two, the two steam inlets 221 are arranged symmetrically with respect to a line connecting the spout 140 and the handle 150, and the steam inlets 221 are installed on one side of the intermediate cover 210 adjacent to the spout 140.

[0061] In these embodiments, generally, when pouring into the liquid heating container, the handle 150 serves as a fulcrum, and two steam inlets 221 are arranged symmetrically about the line connecting the spout 140 and the handle 150. As a result, no matter which way the liquid heating container is tilted, the steam inlet 221 at the top end will not be covered with liquid and will remain conductive, allowing steam to quickly flow out through at least one steam inlet 221, the steam accommodating cavity, and the air guiding passage 30, preventing the risk of excessive pressure due to steam not being able to be released within the kettle body 10 and meeting the need to prevent the liquid heating container from tipping over.

[0062] In some embodiments, as shown in Figures 1, 2, 3, 5 and 6, the liquid heating container further includes a kettle bottom lid 120 installed under the kettle body 10 and a thermostat installed on the kettle bottom lid 120, and the second end of the air guide passage 30 extends into the kettle bottom lid 120, and the terminal opening of the second end of the air guide passage 30 faces the thermostat.

[0063] In these embodiments, the air outlet end, i.e., the second end, of the air guide passage 30 faces the thermostat, which can timely detect the temperature of the steam discharged from the air guide passage 30, and thereby immediately cut off the circuit if the temperature is too high, thereby improving safety.

[0064] Furthermore, a plurality of water outlets are provided on the bottom wall of the kettle bottom cover 120, and the steam and liquid flowing out of the air guide passage 30 are discharged to the outside of the liquid heating container through the water outlets.

[0065] 9, a decompression hole 228 is provided in the bottom wall of the lower cover 220, the decompression hole 228 communicates with the kettle body 10, and the decompression hole 228 is located outside the first buffer chamber 230 and the second buffer chamber 240. The size of the decompression hole is smaller than the size of the steam inlet 221, for example, the diameter of the decompression hole is 1 to 3 mm, and the diameter of the steam inlet 221 is 4 to 8 mm. Therefore, a large amount of steam can enter the steam accommodating cavity through the steam inlet 221.

[0066] In these embodiments, the pressure reduction holes 228 can reduce pressure. For example, when a user lifts the kettle body 10 to pour water, the steam inlets 221 may be blocked by liquid. In this state, the pressure in the kettle body 10 can be released through the pressure reduction holes 228, avoiding the risk of excessive pressure inside the kettle body 10. Furthermore, the pressure reduction holes 228 and the air guide passage 30 are connected to the outside, which can maintain a pressure balance between the inside and outside of the kettle body and favor the outward flow of water. The pressure reduction holes 228 also function as a circulation hole, allowing the liquid inside the kettle cover 20 to circulate back into the kettle body 10 through the pressure reduction holes 228.

[0067] In some embodiments, the air guide passage 30 is disposed within the kettle body 10. For example, the air guide passage 30 is formed by an air guide tube, the upper end of which is connected to the steam outlet of the kettle cover 20, and the air guide tube extends through the internal cavity of the kettle body 10 or between layers of the kettle body to the bottom of the kettle body 10. The outlet of the air guide passage 30 is located at the bottom of the kettle body 10 or on a side wall of the kettle body 10 near the bottom of the kettle body 10.

[0068] In some embodiments, the handle 150 is connected to the kettle body 10, with the upper end of the handle 150 connected to the kettle body 10 near the kettle spout and the lower end of the handle 150 connected to the kettle body 10 near the bottom of the kettle. The air guide passage 30 may be located within the handle 150. For example, the air guide passage 30 may be formed by providing an air guide tube in the handle 150, or the air guide passage 30 may be formed as a hollow structure within the handle 150. The outlet of the air guide passage 30 may be located at the bottom of the handle 150. The air guide passage 30 may pass through the handle, enter the interior of the kettle body 10, and then extend to the bottom of the kettle body 10, with the outlet of the air guide passage 30 located at the bottom of the kettle body 10. In other words, the location of the air guide passage 30 is not limited to the above example, as long as it can guide steam from the kettle cover 20 toward the bottom of the kettle body 10.

[0069] 1, 5 and 6, one side of the kettle mouth 110 is provided with a notch, the steam outlet of the steam accommodating cavity is aligned with the notch, a first end of the handle 150 is connected to the kettle body 10 at the notch, the first end of the handle 150 includes a hollow portion 151, and the first end of the air guiding passage 30 is located in the hollow portion 151. A through-hole 152 is provided in the bottom wall of the hollow portion 151, and the through-hole 152 communicates with the hollow portion 151 and the kettle body 10. The air guiding passage 30 passes through the through-hole 152 and extends into the kettle body 10, then penetrates the bottom wall of the kettle body 10 and extends to the outside of the kettle body 10. The liquid heating vessel further comprises a second sealing ring 153, which is disposed at the first end of the handle 150 and connects the air guide passage 30 with the vapor-accommodating cavity.

[0070] In these embodiments, the air guide passage 30 extends into the kettle body 10 through the hollow portion 151 of the handle 150 and a through-hole 152 provided in the bottom wall of the handle 150, and the second end of the air guide passage 30 passes through the bottom wall of the kettle body 10, is inserted into the kettle bottom lid 120, and extends to the thermostat. Furthermore, a second sealing ring 153 connects the air guide passage 30 and the steam accommodating cavity, thereby improving the sealing of the connection.

[0071] In some embodiments, as an example, optionally, as shown in FIG. 5 , the through hole 152 is provided with an air guide passage upper end sealing ring 310 for sealing the installation gap between the through hole 152 and the air guide passage 30.

[0072] It can be understood that in some embodiments, the lower cover 220 and the middle cover 210 are arranged to surround and form a steam accommodating cavity, and the first buffer chamber 230 and the second buffer chamber 240 are installed in the steam accommodating cavity. In a specific embodiment of the present application, the second sealing ring 153 connects the steam accommodating cavity with the air guiding passage 30. The steam or liquid in the kettle body 10 first enters the first buffer chamber 230 through the steam inlet 221, then flows into the second buffer chamber 240, and then is discharged into the steam accommodating cavity, where it is buffered again before entering the air guiding passage 30. The multi-buffer arrangement prevents the liquid from flowing directly into the air guiding passage 30 due to the high flow rate, which would otherwise cause the liquid to flow out of the kettle body 10 when the liquid heating container is overturned. This further improves the effectiveness of preventing liquid from spilling when the liquid heating container is overturned, ensuring user safety.

[0073] In some embodiments, as an example, as shown in FIG. 5 , a heating plate 130 is provided below the kettle body 10, an avoidance hole for the air guide passage 30 to pass through is provided in the heating plate 130, and a lower end sealing ring 320 of the air guide passage is provided in the avoidance hole to seal the installation gap between the avoidance hole and the air guide passage 30.

[0074] 7, 10, 11 and 12, the kettle cover 20 includes an upper cover 260 that is placed on the intermediate cover 210. The upper cover 260 covers the components placed on the intermediate cover 210, preventing the components from being exposed, and also helps to prevent dust from entering the kettle cover 20 and improves its appearance.

[0075] When using a liquid heating container according to an embodiment of the present invention, if the liquid heating container is tipped over, liquid will enter the steam receiving cavity through steam inlet 221, first buffer chamber 230, and second buffer chamber 240. When the liquid fills air guide passage 30 in kettle cover 20 adjacent to handle 150, a pressure balance is achieved between the inside and outside of the kettle. At this time, even if liquid enters air guide passage 30, the outlet of air guide passage 30 faces upward, so the liquid will not flow out of the kettle, preventing the liquid from spilling when the liquid heating container is tipped over.

[0076] Although the embodiments of the present invention have been described in detail above, those skilled in the art can make various modifications and variations to the embodiments of the present invention without departing from the spirit and scope of the present invention. In the view of those skilled in the art, it will be understood that such modifications and variations are also included within the spirit and scope of the embodiments of the present invention as defined by the claims.
