Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to a liquid heating container. Background Art

[0002] At present, the existing electric kettles are designed with anti-dumping structures to prevent water from overflowing when the kettles are tipped over. Most of the existing anti-dumping structures achieve tipping sealing by setting steel balls inside the kettle lids. However, during use, the steel balls will move and produce abnormal noises, resulting in a poor user experience. Utility Model Content

[0003] The present application aims to at least solve the problem of abnormal noise caused by the rolling of steel balls in the lid of an anti-dumping kettle in the above-mentioned prior art or related art.

[0004] To this end, a first aspect of the present application is to provide a liquid heating container.

[0005] According to one aspect of the utility model, a liquid heating container is provided, which includes: a kettle body, wherein the top of the kettle body is provided with a kettle mouth; a kettle lid, wherein the kettle lid covers the kettle mouth and seals the kettle mouth, wherein the kettle lid is provided with a steam containing chamber, wherein at least one buffer chamber is further provided in the steam containing chamber, wherein the buffer chamber is communicated with the steam containing chamber, wherein the kettle lid is provided with a steam inlet for communicating the interior of the kettle body with the buffer chamber, and a steam outlet for communicating the steam containing chamber with the outside; and an air guiding channel, wherein a first end of the air guiding channel is communicated with the steam outlet, and a second end of the air guiding channel extends to the bottom of the kettle body and is communicated with the outside.

[0006] Compared with the anti-dumping kettle cover in the related art that uses steel balls to block the steam inlet, the liquid heating container proposed in the embodiment of this aspect eliminates the steel balls, making the kettle cover safer, without abnormal noise, and providing a better user experience.

[0007] In addition, according to one aspect of the utility model, the air guide channel is connected to the steam receiving chamber inside the kettle lid, so that the steam in the kettle body can be buffered by the buffer chamber and the steam receiving chamber, and then discharged to the outside through the air guide channel, so as to achieve pressure balance inside and outside the kettle, prevent the liquid in the kettle body from flowing out through the air guide channel, and achieve dumping and overflow prevention. Through the buffer structure, the water and gas buffering time is longer, and the water and gas are not easy to mix together. Moreover, because the flow rate of the gas under high pressure is greater than the flow rate of the liquid, it is more conducive to the gas to be discharged outward, so as to achieve pressure balance inside and outside the kettle body, thereby preventing the liquid from overflowing.

[0008] In some embodiments, the buffer chamber includes a first buffer chamber and a second buffer chamber, the steam inlet is arranged in the first buffer chamber, and the second buffer chamber is communicated with the first buffer chamber and the steam receiving chamber. Through multiple buffers, the air pressure in the kettle body can be fully released, reducing the internal pressure to press the water from the kettle body to the outside of the kettle body.

[0009] In some embodiments, the outer diameter of the kettle body gradually increases from the top to the bottom, and when the kettle body is tilted, the second end of the air guide channel is higher than the first end of the air guide channel. By making the second end of the air guide channel higher than the first end of the air guide channel, the risk of liquid overflow is further avoided.

[0010] In some embodiments, the pot cover includes a middle cover and a lower cover located below the middle cover, the lower surface of the middle cover is provided with an upper enclosure protruding downward and / or the upper surface of the lower cover is provided with a lower enclosure protruding upward, the middle cover and the lower cover are connected to each other to enclose the steam receiving chamber, and the upper enclosure and / or the lower enclosure enclose the buffer chamber. By providing the upper enclosure and / or the lower enclosure, when the middle cover and the lower cover are connected to each other, the steam receiving chamber and the buffer chamber can be formed at the same time, thereby simplifying the installation process.

[0011] In some embodiments, a first enclosure is provided on the lower surface of the middle cover, and a second enclosure is provided on the upper surface of the lower cover. When the middle cover is connected to the lower cover, the first enclosure and the second enclosure enclose to form the first buffer cavity. By providing an upper enclosure on the lower surface of the middle cover and a lower enclosure on the upper surface of the lower cover, it is easier to manufacture and form the first buffer cavity, and it is easier to seal and cooperate with each other after docking.

[0012] In some embodiments, a third enclosure is provided on the lower surface of the middle cover, and a fourth enclosure is provided on the upper surface of the lower cover. When the middle cover is connected to the lower cover, the third enclosure and the fourth enclosure enclose a second buffer chamber, and a first vent is provided on the side wall of the first enclosure and / or the second enclosure; a second vent and a third vent are provided on the side wall of the third enclosure and / or the fourth enclosure, the second vent is connected to the first vent, and the third vent is connected to the steam receiving chamber. By opening through holes on the enclosure side walls of the first buffer chamber and the enclosure side walls of the second buffer chamber, and making the through holes butt against each other, the first buffer chamber and the second buffer chamber can be easily connected to each other, and the structure is simple and easy to manufacture.

[0013] In some embodiments, the lower surface of the middle cover is provided with an upper enclosure protruding downward and the upper surface of the lower cover is provided with a lower enclosure protruding upward, the upper enclosure and the lower enclosure are formed in a ring shape, the upper enclosure is formed integrally with the middle cover, the lower enclosure is formed integrally with the lower cover, the bottom end of the upper enclosure is provided with a first inclined surface, the top end of the lower enclosure is provided with a second inclined surface, the middle cover and the lower cover are connected to each other, so that the first inclined surface abuts against the second inclined surface and has an interference fit. By forming the upper enclosure integrally with the middle cover, the lower enclosure integrally with the lower cover, and realizing the sealing of the buffer cavity through the interference fit of the two inclined surfaces, the structure is simple and the assembly is convenient.

[0014] In some embodiments, the steam inlet is provided on the lower cover and is located in the first buffer cavity; the first buffer cavity is provided with at least two, the steam inlet and the first buffer cavity are provided with at least two, and the second buffer cavity is provided with at least one. By providing two first buffer cavities and two steam inlets, it can be ensured that when one of the steam inlets is blocked by liquid, the steam can enter the steam buffer cavity through the other steam inlet and be discharged outward through the air guide channel.

[0015] In some embodiments, the liquid heating container also includes a pouring spout and a handle that are relatively arranged, the number of the steam inlets is two, the two steam inlets are symmetrically arranged along the line between the pouring spout and the handle, the steam inlet is arranged on the side of the middle cover close to the pouring spout, the second buffer cavity is set to one and is located on the side close to the handle, and the air guide channel is arranged on the side where the handle is located.

[0016] In these embodiments, since the handle is generally used as a fulcrum when the liquid heating container is tipped, two steam inlets are symmetrically arranged on the line between the pouring spout and the handle, so that no matter which direction the liquid heating container is tipped, the steam inlet at the upper end will not be covered by liquid and will be in a conductive state, ensuring that the steam can quickly flow out from at least one steam inlet, the buffer chamber, the steam containing chamber and the air guide channel, avoiding the danger of steam in the kettle being unable to be discharged and excessive pressure, thereby meeting the needs of the liquid heating container in an anti-tipping state.

[0017] In some embodiments, the liquid heating container further comprises: a bottom cover disposed below the kettle body; a thermostat disposed in the bottom cover, the second end of the air guide channel extends into the bottom cover, and the second end of the air guide channel faces the thermostat. In these embodiments, the air outlet of the air guide channel faces the thermostat, and the thermostat can detect the temperature of the steam discharged from the air guide channel in a timely manner, thereby timely cutting off the circuit when the temperature is too high, thereby improving safety.

[0018] In some embodiments, a pressure relief hole is provided on the bottom wall of the lower cover, and the pressure relief hole can connect the steam containing cavity with the kettle body. The pressure relief hole is located outside the first buffer cavity and the second buffer cavity, and the size of the pressure relief hole is smaller than the size of the steam inlet.

[0019] In these embodiments, since the size of the pressure relief hole is smaller than the size of the steam inlet, a large amount of steam will enter the steam pressure relief chamber through the steam inlet, be buffered, and then be discharged outward through the air guide channel. In addition, the pressure relief hole can play a role in pressure relief. For example, when the user lifts the kettle body to pour water, multiple steam inlets may be blocked by liquid. In this state, the pressure relief hole can be used to achieve pressure relief of the kettle body to avoid the danger of excessive pressure inside the kettle body; in addition, the pressure relief hole and the air guide channel are connected to the outside world, so that the pressure inside and outside the kettle body can be balanced, which is conducive to pouring water out. Furthermore, the pressure relief hole can also play a role in reflux, so that the liquid in the kettle lid can flow back into the kettle body through the pressure relief hole.

[0020] In some embodiments, the liquid heating container further comprises: a first sealing ring, which is sleeved at the connection between the lower cover and the middle cover to seal the gap between the lower cover and the middle cover, and the first sealing ring can also seal the gap between the pot cover and the pot body. In these embodiments, a first sealing ring capable of sealing the gap between the lower cover and the middle cover is provided at the connection between the lower cover and the middle cover, thereby improving the sealing performance of the steam receiving chamber.

[0021] In some embodiments, after the middle cover is connected to the lower cover, a circle of slots is formed between the lower cover and the middle cover, and the first sealing ring includes ribs adapted to the slots, and the ribs are buckled in the slots. In these embodiments, the ribs of the first sealing ring are clamped in the slots formed between the lower cover and the middle cover, which facilitates the fixed installation of the first sealing ring. The first sealing ring can cover the joint between the lower cover and the middle cover to achieve sealing. Furthermore, the first sealing ring also achieves sealing between the pot lid and the pot mouth at the same time, and one part achieves sealing of two parts, thereby improving the utilization rate of the parts.

[0022] In some embodiments, the air guide channel is located in the kettle body, or the kettle body is further connected to a handle, and the air guide channel is arranged in the handle. By locating the conductor channel in the kettle body or arranging it in the handle, the air guide channel can be hidden from the outside, thereby improving the aesthetics of the product.

[0023] In some embodiments, a handle is also connected to the kettle body, and the first end of the handle includes a hollow section, and the hollow section is connected to the steam containing chamber through the notch, and the first end of the air guide channel is located in the hollow section; a through hole is provided on the bottom wall of the hollow section, and the second end of the air guide channel extends through the through hole into the kettle body, passes through the bottom wall of the kettle body, and then extends to the outside of the kettle body.

[0024] In these embodiments, the air guide channel passes through the hollow section of the handle and the through hole provided on the bottom wall of the handle and extends into the kettle body, so that the air guide channel can be hidden in the kettle body, improving the aesthetics of the liquid heating container. The second end of the air guide channel passes through the bottom wall of the kettle body and is inserted into the kettle bottom cover until it extends to the thermostat, which can control the on and off of the heater according to the temperature of the steam, preventing the liquid heating container from burning and improving the safety of use.

[0053] Furthermore, in the description of the examples, when it is considered that a detailed description of a well-known related structure or function will cause an ambiguous interpretation of the present invention, such a detailed description will be omitted.

[0054] The following will be combined Figures 1 to 13 Liquid heating vessels of some embodiments of the present application are described.

[0055] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the first aspect of the utility model provides a liquid heating container, comprising: a kettle body 10, the top of the kettle body 10 is provided with a kettle mouth 110, and the outer diameter of the kettle body 10 gradually increases from the top end to the bottom end; a kettle cover 20, the kettle cover 20 covers the kettle mouth 110 and seals the kettle mouth 110, a steam containing chamber is provided in the kettle cover 20, and the steam containing chamber is connected with the inner chamber of the kettle body 10; an air guide channel 30 is provided in the kettle body 10, a first end of the air guide channel 30 is connected with the steam containing chamber, a second end of the air guide channel 30 extends to the bottom of the kettle body 10 and is connected with the outside, and when the kettle body 10 is tilted, the first end of the air guide channel 30 is lower than the second end of the air guide channel 30.

[0056] The liquid heating container proposed in the embodiment of this aspect includes a kettle body 10, a kettle lid 20 and an air guiding channel 30. The kettle lid 20 covers the kettle mouth 110 and seals the kettle mouth 110. When the liquid heating container is tilted, the liquid in the kettle body 10 will not spill out directly from the kettle mouth 110; further, the air guiding channel 30 is connected with the steam containing chamber inside the kettle lid 20, so that the steam in the kettle body 10 can be discharged to the outside through the steam containing chamber and the air guiding channel 30, thereby realizing normal pressure relief and exhaust; further, the kettle lid 20 and the kettle body 10 form an anti-dumping kettle as a whole. The pressure inside and outside the kettle is balanced by the speed difference between the steam and the water flow inside the kettle lid 20. The flow rate of the steam under high pressure is greater than the flow rate of the water flow. Therefore, when the liquid heating container is tilted, the steam will enter the air guiding channel 30 before the liquid and be discharged to the outside, thereby realizing the pressure balance inside and outside the kettle body, preventing the liquid in the kettle body from flowing out, and realizing anti-overflow when tilting.

[0057] In addition, the kettle body 10 is shaped to be small at the top and large at the bottom. When the liquid heating container is tipped over, it is easier to make the second end of the air guide channel 30 connected to the outside higher than the first end connected to the steam containing chamber. Since the pressure balance inside and outside the liquid heating container has been achieved, even if there is liquid in the air guide channel 30, it will not flow to the second end of the air guide channel 30, thereby preventing the liquid in the kettle body 10 from flowing out through the air guide channel 30 and preventing overflow when tipping over.

[0058] Furthermore, compared with the anti-dumping kettle cover 20 in the related art that uses steel balls to block the steam inlet 221, the liquid heating container proposed in the embodiment of this aspect eliminates the steel balls, making the kettle cover 20 safer, without abnormal noise, and providing a better user experience.

[0059] According to one aspect of the embodiment, at least one buffer chamber is further provided in the steam receiving chamber, and the buffer chamber is communicated with the steam receiving chamber. The kettle cover 20 is provided with a steam inlet 221 for communicating the interior of the kettle body 10 with the buffer chamber and a steam outlet for communicating the steam receiving chamber with the outside. The first end of the air guide channel 30 is communicated with the steam outlet, thereby connecting the steam receiving chamber with the outside. The steam in the kettle body 10 will first enter the buffer chamber through the steam inlet 221, then enter the steam receiving chamber, and then enter the air guide channel 30 through the steam outlet. The multiple buffering of the buffer chamber and the steam receiving chamber facilitates the separation of steam and liquid, so that the steam can enter the steam receiving chamber before the liquid and be discharged outward through the air guide channel 30, quickly achieving the internal and external pressure balance of the kettle body 10 and preventing the liquid from flowing out.

[0060] According to one aspect of the embodiment, the buffer chamber can be at least one or more, so as to have a multi-level buffer effect. In the embodiment shown in the drawings, the buffer chamber includes a first buffer chamber 230 and a second buffer chamber 240, and the steam inlet 221 is arranged in the first buffer chamber 230, and the second buffer chamber 240 is communicated with the first buffer chamber 230 and communicated with the steam receiving chamber. The steam in the kettle body 10 enters the first buffer chamber 230 through the steam inlet 221, and then passes through the second buffer chamber 240 and the steam receiving chamber in turn, and finally is discharged outward through the air guide channel 30. Through multiple buffers, it is more conducive to the separation of steam and liquid, so that the steam can enter the steam receiving chamber before the liquid and be discharged outward through the air guide channel 30.

[0061] The pot cover 20 includes a middle cover 210 and a lower cover 220 located below the middle cover 210, the lower surface of the middle cover 210 is provided with an upper enclosure protruding downward and / or the upper surface of the lower cover 220 is provided with an upper enclosure protruding upward, the middle cover 210 and the lower cover 220 are connected to each other, and the steam receiving chamber is enclosed, and the upper enclosure and / or the lower enclosure are enclosed to form at least one buffer chamber, for example, a first buffer chamber 230 and a second buffer chamber 240. As an example, the upper enclosure can be formed integrally with the middle cover 210 or formed in parts and then connected together, and the lower enclosure can be formed integrally with the lower cover 220 or formed in parts and then connected together. By forming in one piece, the subsequent installation process can be simplified. According to the embodiment of the utility model, only an upper enclosure may be formed, and the upper enclosure abuts against the lower cover 220 to form a buffer cavity, or only a lower enclosure may be formed, and the lower enclosure abuts against the lower surface of the middle cover 210 to form a buffer cavity, or both an upper enclosure and a lower enclosure may be formed, and the upper enclosure and the lower enclosure are connected to form a buffer cavity. A more detailed description is given below in conjunction with the accompanying drawings.

[0062] like Figure 4 , Figure 7 , Figure 8 , Fig. 9 and Fig.13 As shown, in some embodiments, the pot cover 20 includes a middle cover 210 and a lower cover 220, the middle cover 210 is connected to the top of the lower cover 220, and is surrounded by the lower cover 220 to form a steam receiving chamber, and the lower cover 220 is provided with at least two steam inlets 221 penetrating the lower cover 220; at least two first buffer chambers 230 are provided in the steam receiving chamber, and steam inlets 221 are provided on the lower cover 220 at positions corresponding to the first buffer chambers 230.

[0063] In these embodiments, the middle cover 210 and the lower cover 220 are arranged to form a steam receiving chamber, and at least two first buffer chambers 230 are arranged in the steam receiving chamber, and the first buffer chambers 230 are connected one by one with the steam inlet 221 arranged on the lower cover 220. The steam in the kettle body 10 first enters the first buffer chamber 230 through the steam inlet 221 for buffering and deceleration, and then is discharged into the steam receiving chamber for re-buffering to achieve pressure relief, and then is discharged into the air guide channel 30, which can prevent the excessive pressure in the kettle cover 20 from directly rushing into the air guide channel 30, making the steam discharge smoother; similarly, in the case of the liquid heating container tipping over, the liquid in the kettle body 10 will also first enter the first buffer chamber 230 through the steam inlet 221, and then be discharged into the steam receiving chamber. The first buffer chamber 230 can play a buffering role to prevent the liquid from flowing into the steam receiving chamber and then directly rushing into the air guide channel 30 when tipping over, resulting in excessive liquid flow rate and rushing out of the air guide channel 30 to the outside of the kettle body 10.

[0064] In some embodiments, Figure 4 , Figure 7 , Figure 8 , Fig. 9 As shown, the upper enclosure includes a first enclosure 211 disposed on the lower surface of the middle cover 210, and the lower enclosure includes a second enclosure 222 disposed on the upper surface of the lower cover 220. When the middle cover 210 is connected to the lower cover 220, the first enclosure 211 and the second enclosure 222 are enclosed to form a first buffer cavity 230. In this way, the first enclosure 211 and the second enclosure 222 are enclosed to form the first buffer cavity 230, which has a simple structure and is conducive to the processing and production of the pot cover 20.

[0065] like Figure 8 , Fig. 9 and Fig.12 As shown, in some embodiments, a first inclined surface 212 is disposed at the bottom end of the first enclosure 211 , and a second inclined surface 223 is disposed at the top end of the second enclosure 222 . The first inclined surface 212 and the second inclined surface 223 abut against each other and are interference fit.

[0066] In these embodiments, the contact surfaces of the first enclosure 211 and the second enclosure 222 are both inclined surfaces. When the middle cover 201 and the lower cover 220 are coupled to each other by fasteners, the first inclined surface 212 and the second inclined surface 223 are interference fit to produce slight plastic deformation, thereby achieving a tight seal of the first buffer cavity 230 and improving the sealing performance of the first buffer cavity 230.

[0067] Furthermore, in some embodiments, Figure 8 , Fig. 9 , Fig.10 , Fig.11 and Fig.12As shown, a first fixing column 270 is also provided in the middle of the area surrounded by the first enclosure 211, and a second fixing column 271 is also provided in the middle of the area surrounded by the second enclosure 222. The first fixing column 270 and the second fixing column 271 are plugged into or abutted against each other, and are connected by fasteners 272 (for example, screws) to achieve a fastened connection between the first enclosure 211 and the second enclosure 222, so that the first enclosure 211 and the second enclosure 222 produce slight plastic deformation, so that the first buffer cavity 230 achieves a tight fit and sealing in the assembly position.

[0068] In some embodiments, a first vent hole is disposed on the side wall of the first enclosure 211 and / or the second enclosure 222; Figure 4 , Figure 7 , Figure 8 , Fig. 9 As shown, the upper enclosure also includes a third enclosure 213 arranged on the lower surface of the middle cover 210, and the lower enclosure also includes a fourth enclosure 224 arranged on the upper surface of the lower cover 220. When the middle cover 210 is connected to the lower cover 220, the third enclosure 213 and the fourth enclosure 224 are combined to form a second buffer cavity 240, and the side walls of the third enclosure 213 and / or the fourth enclosure 224 are provided with a second vent hole and a third vent hole, the second vent hole is connected to the first vent hole, and the third vent hole is connected to the steam containing cavity.

[0069] In these embodiments, the first buffer chamber 230 and the second buffer chamber 240 are connected via a first vent hole and a second vent hole arranged on the side wall. The cooperation between the second buffer chamber 240 and the first buffer chamber 230 can play a double buffering role. 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 receiving chamber, thereby further enhancing the effect of preventing overflow when pouring.

[0070] like Figure 8 , Fig. 9 and Fig.12 As shown, in some embodiments, the bottom end of the third enclosure 213 is provided with a third inclined surface 2131, and the top end of the fourth enclosure 224 is provided with a fourth inclined surface 2241, and the third inclined surface 2131 abuts against and has an interference fit with the fourth inclined surface 2241. In this way, the contact surfaces of the third enclosure 213 and the fourth enclosure 224 abutting against each other are both inclined surfaces, and the third inclined surface 2131 and the fourth inclined surface 2241 have an interference fit, resulting in slight plastic deformation, thereby achieving a tight fit seal of the second buffer cavity 240 and improving the sealing performance of the second buffer cavity 240.

[0071] Furthermore, if Figure 8 , Fig. 9 , Fig.10 , Fig.11 and Fig.12As shown, in some embodiments, a third fixing column 280 is further provided in the middle of the area enclosed by the third enclosure 213, and a fourth fixing column 281 is further provided in the middle of the area enclosed by the fourth enclosure 224. The third fixing column 280 and the fourth fixing column 281 are plugged into or abutted against each other, and are connected by fasteners 272 (for example, screws) to achieve a fastened connection between the third enclosure 213 and the fourth enclosure 224, so that the third enclosure 213 and the fourth enclosure 224 produce slight plastic deformation, so that the second buffer cavity 240 achieves a tight fit and sealing in the assembly position.

[0072] In some embodiments, Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 and Fig.12 As shown, the liquid heating container also includes: a first sealing ring 40, which is sleeved at the connection between the lower cover 220 and the middle cover 210 to seal the gap between the lower cover 220 and the middle cover 210. The first sealing ring 40 can also seal the gap between the pot cover 20 and the pot body 10.

[0073] In these embodiments, a first sealing ring 40 capable of sealing the gap between the lower cover 220 and the middle cover 210 is provided at the connection between the lower cover 220 and the middle cover 210 to improve the sealing performance of the steam receiving chamber.

[0074] In some embodiments, Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 and Fig.12 As shown, after the middle cover 210 is connected to the lower cover 220 , a circle of slots 250 is formed between the lower cover 220 and the middle cover 210 , and the first sealing ring 40 includes ribs 410 adapted to the slots 250 , and the ribs 410 are buckled in the slots 250 .

[0075] In these embodiments, the rib 410 of the first sealing ring 40 is clamped in the clamping groove 250 formed between the lower cover 220 and the middle cover 210, which facilitates the fixed installation of the first sealing ring 40. The first sealing ring 40 can cover the joint between the lower cover 220 and the middle cover 210 to achieve sealing. Furthermore, the first sealing ring 40 also achieves sealing between the pot cover 20 and the pot mouth 110 at the same time, and one part achieves sealing of two parts, thereby improving the utilization rate of parts.

[0076] Specifically, the middle cover 210 and the lower cover 220 are connected to form a steam containing chamber, and after the middle cover 210 and the lower cover 220 are assembled, a circle of grooves 250 are formed on the outer wall, and ribs 410 are provided on the inner wall of the first sealing ring 40, and the ribs 410 are buckled into the grooves 250. The gap between the lower cover 220 and the middle cover 210 is sealed by the ribs 410 of the first sealing ring 40.

[0077] In some embodiments, Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the liquid heating container also includes a pouring spout 140 and a handle 150 that are arranged opposite to each other, and there are two steam inlets 221. The two steam inlets 221 are symmetrically arranged along the line between the pouring spout 140 and the handle 150, and the steam inlet 221 is arranged on one side of the middle cover 210 close to the pouring spout 140.

[0078] In these embodiments, since the handle 150 is generally used as a fulcrum when the liquid heating container is tipped, two steam inlets 221 are symmetrically arranged on the line between the pouring spout 140 and the handle 150, so that no matter which direction the liquid heating container is tipped, the steam inlet 221 at the upper end will not be covered by liquid and will be in a conductive state, ensuring that steam can quickly flow out from at least one steam inlet 221, the steam containing cavity and the air guide channel 30, thereby avoiding the danger of steam in the kettle body 10 being unable to be discharged and excessive pressure, thereby meeting the needs of the liquid heating container in an anti-tipping state.

[0079] In some embodiments, Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the liquid heating container also includes: a kettle bottom cover 120, which is arranged below the kettle body 10; a thermostat, which is arranged in the kettle bottom cover 120, and the second end of the air guide channel 30 extends into the kettle bottom cover 120, and the second end port of the air guide channel 30 faces the thermostat.

[0080] In these embodiments, the air outlet end of the air guide channel 30 faces the thermostat, and the thermostat can timely detect the temperature of the steam discharged from the air guide channel 30, so as to cut off the circuit in time when the temperature is too high, thereby improving safety.

[0081] 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 channel 30 can be discharged to the outside of the liquid heating container through the water outlets.

[0082] In some embodiments, Fig. 9As shown, a pressure relief hole 228 is provided on the bottom wall of the lower cover 220, and the pressure relief hole 228 can be connected to the kettle body 10, and the pressure relief hole 228 is located outside the first buffer cavity 230 and the second buffer cavity 240. The size of the pressure relief hole is smaller than the size of the steam inlet 221. For example, the diameter of the pressure relief hole is 1-3 mm, and the diameter of the steam inlet 221 is 4-8 mm. Therefore, a large amount of steam will enter the steam receiving cavity through the steam inlet 221.

[0083] In these embodiments, the pressure relief hole 228 can relieve pressure. For example, when the user lifts the kettle body 10 to pour water, the multiple steam inlets 221 may be blocked by liquid. In this state, the pressure relief hole 228 can be used to relieve pressure on the kettle body 10 to avoid the danger of excessive pressure inside the kettle body 10. In addition, the inside of the kettle body is connected to the outside world through the pressure relief hole 228 and the air guide channel 30. When pouring water out through the kettle mouth, external gas can enter the kettle body, so that the pressure inside and outside the kettle body is balanced, which is conducive to pouring water out. The pressure relief hole 228 can also play a reflux role, so that the liquid in the kettle cover 20 can flow back into the kettle body 10 through the pressure relief hole 228.

[0084] In some embodiments, the air guide channel 30 is disposed in the kettle body 10. For example, the air guide channel 30 is formed by an air guide pipe, the upper end of the air guide pipe is connected to the steam outlet in the kettle cover 20, and the air guide pipe passes through the inner cavity of the kettle body 10 or through the interlayer of the kettle body to extend to the bottom of the kettle body 10. The outlet of the air guide channel 30 can be disposed at the bottom of the kettle body 10 or on the side wall of the kettle body 10 near the bottom of the kettle body 10.

[0085] In some embodiments, a handle 150 is connected to the kettle body 10, the upper end of the handle 150 is connected to the kettle body 10 near the kettle mouth, and the lower end of the handle 150 is connected to the kettle body 10 near the kettle bottom. The air guide channel 30 can be located in the handle 150. For example, an air guide tube can be provided in the handle 150 to form the air guide channel 30, or the interior of the handle 150 can be formed into a hollow structure to serve as the air guide channel 30. The outlet of the air guide channel 30 can be provided at the lower part of the handle 150. The air guide channel 30 can also enter the interior of the kettle body 10 after passing through the handle, and then extend to the bottom of the kettle body 10, so that the outlet of the air guide channel 30 is provided at the bottom of the kettle body 10. In short, the arrangement of the air guide channel 30 is not limited to the above example, as long as the steam can be guided from the kettle cover 20 toward the bottom of the kettle body 10.

[0086] In some embodiments, Figure 1 , Figure 5 and Figure 6As shown, a notch is provided on one side of the kettle mouth 110, and the steam outlet of the steam receiving chamber is aligned with the notch. The 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 section 151, and the port of the first end of the air guide channel 30 is located in the hollow section 151; a through hole 152 is provided on the bottom wall of the hollow section 151, and the through hole 152 connects the hollow section 151 and the kettle body 10. The air guide channel 30 extends into the kettle body 10 through the through hole 152, and then extends to the outside of the kettle body 10 through the bottom wall of the kettle body 10. The liquid heating container also includes a second sealing ring 153, which is provided at the first end of the handle 150 and connects the air guide channel 30 and the steam receiving chamber.

[0087] In these embodiments, the air guide channel 30 extends into the kettle body 10 through the hollow section 151 of the handle 150 and the through hole 152 provided on the bottom wall of the handle 150, and the second end of the air guide channel 30 passes through the bottom wall of the kettle body 10 and is inserted into the kettle bottom cover 120 until it extends to the thermostat. Furthermore, the air guide channel 30 and the steam receiving chamber are connected by the second sealing ring 153, which can improve the sealing of the connection.

[0088] Further, in some embodiments, as an example, optionally, as Figure 5 As shown, an air guide channel upper end sealing ring 310 is provided in the through hole 152 , which is used to seal the installation gap between the through hole 152 and the air guide channel 30 .

[0089] It can be understood that, in some embodiments, the steam receiving chamber is formed by the lower cover 220 and the middle cover 210, and the first buffer chamber 230 and the second buffer chamber 240 are arranged in the steam receiving chamber. In a specific embodiment of the present application, the second sealing ring 153 connects the steam receiving chamber and the air guide channel 30. The steam or liquid in the kettle body 10 first enters the first buffer chamber 230 through the steam inlet 221, and then flows into the second buffer chamber 240, and then is discharged into the steam receiving chamber. After being buffered again by the steam receiving chamber, it enters the air guide channel 30. Through multiple buffering, the liquid is prevented from directly rushing into the air guide channel 30 during pouring, resulting in excessive liquid flow rate and rushing out of the air guide channel 30 to the outside of the kettle body 10, which can further enhance the anti-overflow effect and ensure the safety of users.

[0090] In some embodiments, as an example, optionally, Figure 5 As shown, a heating plate 130 is provided below the kettle body 10, and an avoidance hole for the air guide channel 30 to pass through is provided on the heating plate 130, and a sealing ring 320 at the lower end of the air guide channel is provided in the avoidance hole for sealing the installation gap between the avoidance hole and the air guide channel 30.

[0091] In some embodiments, Figure 7 , Fig.10 , Fig.11 and Fig.12 As shown, the pot cover 20 also includes an upper cover 260, which is arranged above the middle cover 210. The upper cover 260 can cover the components installed on the middle cover 210 to prevent the components from being exposed, and can also play a role in dust prevention and improving the aesthetics of the pot cover 20.

[0092] In the liquid heating container provided in the embodiment of the present invention, during the pouring process of the liquid heating container, the liquid will enter the steam receiving chamber through the steam inlet 221, the first buffer chamber 230, and the second buffer chamber 240. When the liquid fills the air guide channel 30 inside the pot cover 20 close to the handle 150, the pressure inside and outside the pot has been balanced. At this time, even if the liquid enters the air guide channel 30, the liquid will not flow out of the pot because the outlet of the air guide channel 30 is facing upward, thereby achieving overflow prevention when pouring.

[0093] Although the embodiments of the present invention have been described in detail above, those skilled in the art may make various modifications and variations to the embodiments of the present invention without departing from the spirit and scope of the present invention. It should be understood that, in the opinion of those skilled in the art, these modifications and variations will still fall within the spirit and scope of the embodiments of the present invention as defined in the claims.
