[0021] The steam inlet of the buffer extension channel communicates with the accommodation cavity, and the steam outlet of the buffer extension channel communicates with the main channel. During heating, the water in the liquid heating container generates steam, and the steam rises and flows into the steam channel. This buffer extension channel can extend the flow path of the steam in the steam channel.

[0036] Refer to Figure 1, in the prior art, a steam passage 131 is provided inside the lid assembly 120. The steam passage 131 includes an intake section 135 extending in the vertical direction (up and down), and an outlet section 136 extending in the horizontal direction (left and right). One end of the intake section 135 can communicate with the accommodation cavity 111 provided in the kettle body assembly 116, and the other end communicates with the outlet section 136. The outlet section 136 extends at least in the direction of the water outlet 121 to communicate with the water outlet 121. Therefore Figure 1 The way the lid assembly 120 discharges steam in Figure 1 is as follows: when heating, the water in the liquid heating container 100 generates steam. The steam rises and flows into the intake section 135, and then flows into the outlet section 136. When the user performs a pouring action, the steam in the outlet section 136 flows out along with the liquid in the accommodation cavity 111. And from Figure 1 it can be seen that the length of the intake section 135 of the steam passage 131 is relatively short and is directly opposite to the opening of the accommodation cavity 111. When the water boils, a large amount of steam will directly rush into the outlet section 136, and there is a large amount of steam in the steam passage 131 with a relatively high pressure. When the water outlet 121 is opened, the amount of steam ejected is large and the impact intensity is high, which easily causes the user to be scalded by the steam when pouring water, and is not conducive to the use safety of the liquid heating container 100.

[0037] In view of this, the present utility model proposes a liquid heating container 100.

[0038] In the embodiment of the present utility model, as Figures 2 to 6 shown, the liquid heating container 100 includes:

[0039] A container body 110 having an accommodation cavity 111, and a steam switch 115 is provided inside the container body 110; and

[0040] A lid assembly 120, the lid assembly 120 can cover the accommodation cavity 111, the lid assembly 120 has a water outlet 121 communicating with the accommodation cavity 111, the lid assembly 120 includes a steam assembly 130, and a steam passage 131 is provided inside the steam assembly 130. The steam passage 131 includes a buffer extension passage 132 and a main passage 133. The steam inlet 132a of the buffer extension passage 132 communicates with the accommodation cavity 111, the steam outlet 132b of the buffer extension passage 132 communicates with the main passage 133, one end of the main passage 133 communicates with the water outlet 121, and the other end extends towards the steam switch 115 so that the steam in the steam passage 131 triggers the steam switch 115.

[0041] Specifically, an accommodation cavity 111 is provided inside the container body 110. The cover assembly 120 can cover the accommodation cavity 111, and when the cover assembly 120 covers the accommodation cavity 111, it can be hermetically connected to the container body 110 through a sealing structure such as a sealing ring; the cover assembly 120 can also be opened relative to the accommodation cavity 111 to facilitate the user to add water. When heating, the water in the liquid heating container 100 generates steam, and the steam rises and flows into the steam channel 131. The steam channel 131 includes a buffer extension channel 132 and a main channel 133, and the steam inlet 132a of the buffer extension channel 132 communicates with the accommodation cavity 111, and the steam outlet 132b communicates with the main channel 133, so that the steam first enters the buffer extension channel 132. The buffer extension channel 132 can extend the flow path of the steam in the steam channel 131. On the one hand, it slows down the flow speed of the steam, and on the other hand, it promotes the liquefaction of the steam, thereby reducing the amount of steam in the steam channel 131 and reducing the pressure in the steam channel 131. Then the steam enters the main channel 133. Figure 2 The direction indicated by the arrow in Figure 2 is the flow direction of the steam, and the steam entering the main channel 133 is divided into two parts. One part enters the container body 110 through the main channel 133. As the temperature rises, when the water boils and reaches the preset steam pressure, the steam switch 115 is triggered, causing the liquid heating container 100 to stop working; the other part flows in the direction of the water outlet 121 from the main channel 133. When the user performs a pouring action, the steam in the main channel 133 flows out with the liquid in the accommodation cavity 111.

[0042] Wherein, the water outlet 121 is used to pour out the liquid in the accommodation cavity 111. The cover assembly 120 is also provided with a water flow channel 128. The water outlet 121 is communicated with the accommodation cavity 111 through the water flow channel 128. And a water outlet valve 122 is arranged on one side of the water flow channel 128 facing the accommodation cavity 111. The water outlet valve 122 is configured as a normally closed valve, so as to reduce heat loss during the heating process and reduce the possibility that steam directly discharges from the water outlet 121 during the heating process. And in an embodiment, the water outlet valve 122 has a blocking portion 122a. The air outlet of the main channel 133 is located above the blocking portion 122a, and the blocking portion 122a blocks the air outlet and the water flow channel 128. That is to say, the water outlet valve 122 can not only control the communication between the water flow channel 128 and the accommodation cavity 111, but also control the communication between the water flow channel 128 and the main channel 133 and the communication between the main channel 133 and the accommodation cavity 111. So that when the hot water is not completely boiled, the steam in the main channel 133 and the steam in the accommodation cavity 111 cannot flow out from the water outlet 121. After the hot water boils and the user pours out the hot water, the water vapor in the main channel 133 is discharged from the water outlet 121 along with the water flow. And the steam outlet 132b of the buffer extension channel 132 is communicated with the main channel 133 and is located between the two ends of the main channel 133, so that the steam entering the main channel 133 can be divided into two parts and flow towards the two ends of the main channel 133 respectively. The buffer extension channel 132 can be configured as a steam channel 131 arranged in the cover assembly 120 and extending in the horizontal direction. Therefore, the buffer extension channel 132 can be meanderingly arranged in the steam assembly 130, so as to avoid a large amount of steam directly flushing into the main channel 133 and reduce the ejection pressure of the steam.

[0043] Referring to Figures 3 to 5 , in an embodiment, the buffer extension channel 132 is arranged below the main channel 133, and the steam inlet 132a is arranged at the bottom of the buffer extension channel 132, and the steam outlet 132b is arranged at the top of the buffer extension channel 132. Specifically, the buffer extension channel 132 is arranged below the main channel 133. On the one hand, it ensures that the steam enters the buffer extension channel 132 before entering the main channel 133. On the other hand, it improves the layout rationality of the steam channel 131 and helps the arrangement of the buffer extension channel 132. The steam outlet 132b is arranged at the top of the buffer extension channel 132, that is, the steam outlet 132b is arranged at one end of the buffer extension channel 132 facing the main channel 133, so as to facilitate the communication between the buffer extension channel 132 and the main channel 133. The steam inlet 132a is arranged at the bottom of the buffer extension channel 132, that is, the steam inlet 132a faces the accommodation cavity 111. On the one hand, it is convenient for the buffer extension channel 132 to communicate with the accommodation cavity 111. On the other hand, part of the steam is condensed and liquefied in the buffer extension channel 132, which is convenient for the condensation and reflux of the steam.

[0044] Referring to Figure 5, in one embodiment, the steam assembly 130 includes a steam cartridge 123 disposed on the cover assembly 120. A plurality of baffles are provided in the steam cartridge 123 to form a buffer extension channel 132 in the steam cartridge 123. The steam outlet 132b and the steam inlet 132a are separated by the baffles. Specifically, the steam cartridge 123 includes a chassis 124 and a top cover 125 covering the chassis 124. The plurality of baffles are disposed on the chassis 124 to form a steam groove on the chassis 124. The top cover 125 covers the chassis 124, thereby forming the buffer extension channel 132, which not only facilitates the processing of the steam cartridge 123 but also effectively utilizes the space inside the steam cartridge 123. The steam outlet 132b is correspondingly disposed on the top cover 125, and the steam inlet 132a is correspondingly disposed on the chassis 124. Moreover, the steam outlet 132b and the steam inlet 132a are separated by the baffles, so as to prevent the steam outlet 132b and the steam inlet 132a from being directly communicated.

[0045] Referring to Figures 2 to 6 , in one embodiment, the buffer extension channel 132 includes a plurality of communication segments 134 that are alternately arranged in sequence from outside to inside. The communication segments 134 extend along the circumferential direction of the steam cartridge 123, and two adjacent communication segments 134 are connected in a circuitous manner, so that the flow directions of the steam in two adjacent communication segments 134 are arranged in opposite directions. Specifically, that is, the buffer extension channel 132 extends from outside to inside along the circumferential direction of the chassis 124. To adapt to the shape of the cover assembly 120, the chassis 124 of the steam cartridge 123 is configured as a semicircle. Assuming that the first segment 134a is the segment of the plurality of communication segments 134 located at the outermost periphery of the chassis 124, the first segment 134a encloses at least 1 / 2 of the circumference of the chassis 124. In this embodiment, the steam inlet 132a is disposed on one side of the chassis 124 close to the arc edge. The first segment 134a extends from one side of the arc edge towards the straight edge, and then at least bypasses the straight edge and extends in the opposite direction towards the inside of the first segment 134a to form another communication segment 134 (temporarily designated as the second segment 134b). Therefore, the flow directions of the steam in the first segment 134a and the second segment 134b are arranged in opposite directions, further providing a blocking effect on the steam and promoting the liquefaction of the steam in the steam channel 131.

[0046] Therefore, there is at least one circuitous position between the communication segments 134 and between two adjacent communication segments 134, thereby further changing the flow direction of the buffer extension channel 132 and promoting the liquefaction of the steam in the steam channel 131. Referring to Figure 5 and Figure 6, the detour position refers to a position within the buffer extension channel 132 where the steam flow direction can be changed, but the magnitude of the angle of change in the flow direction is not restricted. For example, the detour position is configured to be provided at two sections of the extended buffer flow path that are interconnected and perpendicular to each other. In this case, when the steam flows through the connection of the two ends in sequence, the angle of change in the flow direction is 90°; or, the detour position is configured to be provided at two sections of the extended buffer flow path that are interconnected and parallel to each other. In this case, when the steam flows through the connection of the two ends in sequence, the angle of change in the flow direction is 180°. The detour position of the buffer extension channel 132 can change the extension direction of the buffer extension channel 132, so that the buffer extension flow path can be serpentinely arranged within the steam assembly 130, thereby increasing the steam flow path, and the detour position can change the steam flow direction, thereby providing a buffering effect for the steam flow.

[0047] Preferably, the connecting section 134 has a first channel extending in a first direction and a second channel extending in a second direction, and the first direction and the second direction are perpendicularly arranged. The connection of the first channel and the second channel forms a detour position. Thus, when the liquid heating container 100 is in a tilted state, at least a part of at least one of the first channel and the second channel is higher than the liquid level in the liquid heating container 100. That is, when the liquid heating container 100 is in a tilted state, no liquid forms a passage in at least one of the channels in the buffer extension channel 132, so that the liquid cannot flow out through the buffer extension channel 132 and will not overflow the cover assembly 120 to scald the user, and it can be tilted arbitrarily, thereby achieving the purpose of preventing the steam channel 131 from being tilted.

[0048] Furthermore, the buffer extension channel 132 further includes an intake section 135 communicating with the steam inlet 132a and an outlet section 136 communicating with the steam outlet 132b. The intake section 135 communicates with the connecting section 134 located at the outermost periphery of the steam cartridge 123, and the outlet section 136 communicates with the connecting channel located at the innermost periphery of the steam cartridge 123, and the intake section 135 and the outlet section 136 are adjacently arranged. Specifically, the intake section 135 and the outlet section 136 are adjacently arranged, that is, they are separated by a baffle, and the steam inlet 132a communicates with the intake section 135 located at the outermost periphery of the steam cartridge 123. The intake section 135 communicates with the connecting section 134 located at the outermost periphery of the steam cartridge 123, and the outlet section 136 communicates with the connecting channel located at the innermost periphery of the steam cartridge 123. Thus, after the steam in the accommodation cavity 111 enters the buffer extension channel 132 through the steam inlet 132a, it must flow through the entire buffer extension channel 132 before it can flow out through the steam outlet 132b.

[0049] Refer to Figure 2 and Figure 4, in one embodiment, the steam inlet 132a is provided on the side of the cover assembly 120 away from the water outlet 121. Thus, when the user pours water, the water flow will not flow back into the steam channel 131 in the reverse direction, and it can also reduce the distance from the steam flow channel to the steam switch 115 and shorten the flow path of the steam to the steam switch 115. And the steam inlet 132a is generally arranged close to the kettle handle assembly 117. When the liquid heating container 100 is tilted, due to the blocking effect of the kettle handle assembly 117, the steam inlet 132a is located at a higher position of the cover assembly 120, thereby further reducing the possibility that the liquid heating container 100 is tilted and the water overflows the cover assembly 120 to scald the user.

[0050] Refer to Figure 2 and Figure 3 , in one embodiment, an anti-tipping valve structure 140 is installed at the steam inlet 132a. When the liquid heating container 100 is tilted, the anti-tipping valve structure 140 can be automatically closed to block the steam inlet 132a, reducing the possibility that the water in the accommodation cavity 111 enters the steam channel 131 through the steam inlet 132a, achieving the purpose of preventing the liquid heating container 100 from tipping over.

[0051] In one embodiment, the anti-tipping valve structure 140 includes a valve body bracket 141 and a valve body 142 installed below the steam inlet 132a. The valve body bracket 141 forms a limiting space 144, and the valve body 142 is movably installed in the limiting space 144. The limiting space 144 restricts the up and down movement of the intake valve body 142. The valve body bracket 141 is provided with a through hole 143 communicating the steam inlet 132a and the accommodation cavity 111;

[0052] Under the action of gravity, the valve body 142 moves downward to block the through hole 143. Under the action of steam, the valve body 142 moves upward to open the through hole 143;

[0053] When the liquid heating container 100 is tilted, under the action of gravity, the valve body 142 moves in the direction close to the steam inlet 132a under the restriction of the limiting space 144 to block the steam inlet 132a.

[0054] Specifically, the valve body support 141 is disposed below the steam inlet 132a. The valve body support 141 can enclose a limiting space 144 for placing the valve body 142 below the steam inlet 132a. The valve body 142 is movably installed in the limiting space 144. Under the limitation of the limiting space 144, the valve body 142 can move up and down. Therefore, the inner diameter of the limiting space 144 is slightly larger than the diameter of the valve body 142, so as to ensure that the valve body 142 can move up and down in the limiting space 144 and also limit the horizontal offset of the valve body 142. The valve body support 141 is provided with a through hole 143. Under the action of gravity, the valve body 142 can block the through hole 143. Therefore, the through hole 143 can be provided at the bottom and / or side of the valve body support 141. After the water is heated, the steam pressure in the accommodation cavity 111 gradually increases, and the steam does work against the gravity of the valve body 142, thereby pushing the valve body 142 upward to open the through hole 143 so that the through hole 143 communicates with the steam inlet 132a.

[0055] When the liquid heating container 100 is tilted, the direction of the cover assembly 120 changes. Under the action of gravity, it moves along the guiding surface 145 towards the direction close to the steam inlet 132a. The guiding surface 145 has a guiding function, thereby blocking the steam inlet 132a and reducing the possibility of the water in the accommodation cavity 111 entering the steam channel 131 through the steam inlet 132a, achieving the purpose of preventing the liquid heating container 100 from tipping over. Therefore, preferably, the side wall of the limiting space 144 is provided with a guiding surface 145, and the guiding surface 145 is inclined so that the limiting space 144 is gradually expanded along the direction close to the steam inlet 132a. If the liquid heating container 100 is horizontally tilted, at this time the cover assembly 120 is vertically arranged, and along the direction close to the steam inlet 132a, the guiding surface 145 extends downward, thereby providing a guiding function for the movement of the valve body 142 towards the steam inlet 132a, thereby blocking the steam inlet 132a. Therefore, the guiding surface 145 can guide the movement of the valve body 142. Preferably, the limiting space 144 is configured in the shape of a frustum of a cone.

[0056] Preferably, the valve body 142 is configured as a sphere, thereby reducing the frictional resistance between the valve body 142 and the valve body support 141. When the liquid heating container 100 is tilted, it is convenient for the valve body 142 to roll towards the steam inlet 132a, thereby improving the anti-tipping effect of the liquid heating container 100. Of course, in other embodiments, the valve body 142 can also be configured in the shape of a cone, a frustum of a cone or a cylinder.

[0057] In another embodiment, the anti-tipping valve structure 140 is configured to be rotatably mounted on a gravity structure below the steam box 123. The gravity structure includes a mounting ring and an anti-tipping portion disposed at an angle. The mounting ring is rotatably mounted on the steam inlet 132a. The anti-tipping portion is horizontally disposed, and an air inlet section 135 communicating with the mounting ring is provided at one end of the anti-tipping portion. The air inlet section 135 extends horizontally, and a gravity block is mounted at the other end. When the liquid heating container 100 is tilted, the gravity block drives the anti-tipping portion to rotate due to its own weight, so that the opening of the air inlet section 135 faces upward, and no matter how the liquid heating container 100 is tilted, the opening of the air inlet section 135 always faces upward (that is, in a direction away from the liquid level in the accommodation cavity 111), thereby achieving the purpose of preventing the liquid heating container 100 from tipping over.

[0058] In one embodiment, as Figures 2 to 4 shown, the main channel 133 is provided with an air inlet communicating with the steam inlet 132a, and a blocking portion 137 is provided on the side of the air inlet facing the water outlet 121. The blocking portion 137 can block the steam from flowing in the direction of the water outlet 121 to reduce the amount of steam flowing to the water outlet 121. Specifically, the blocking portion 137 can reduce the local flow area of the main channel 133, thereby reducing the steam flow rate to the water outlet 121, increasing the proportion of steam flowing from the main channel 133 to the steam switch 115, and further increasing the sensitivity of triggering the steam switch 115. Among them, the blocking portion 137 is formed by bulging from the bottom of the main channel 133 into the main channel 133.

[0059] Referring again to Figure 2 and Figure 3 , in one embodiment, the container body 110 includes a kettle body assembly 116 and a kettle handle assembly 117. One end of the guiding channel 112 is connected to the main channel 133, and the other end passes through the kettle handle assembly 117 and extends towards the bottom of the kettle body assembly 116. The steam switch 115 is disposed at the other end of the guiding channel 112. Specifically, since there is a large installation space at the bottom of the kettle body assembly 116, the steam switch 115 is disposed at the bottom of the kettle body assembly 116, which facilitates the installation of the steam switch 115. The guiding channel 112 extends to the bottom of the kettle body assembly 116 through the kettle handle assembly 117, and the steam switch 115 is disposed at the end of the guiding channel 112 away from the steam channel 131, so that the steam after triggering the steam switch 115 can be directly discharged from the drain hole at the bottom of the kettle body assembly 116. Compared with the steam switch 115 being disposed on the kettle body assembly 116, it not only reduces the installation space of the steam switch 115, but also helps the steam to be discharged after triggering the steam switch 115, reducing the possibility of scalding the user by steam.

[0060] It is understandable that in order to reduce the possibility of overheating of the handle assembly 117, the handle assembly 117 is covered with heat-insulating material. In other embodiments, the steam switch 115 may also be disposed at the connection between the handle assembly 117 and the lid assembly 120, or on one side of the kettle body assembly 116.

[0061] In other embodiments, the guiding passage may also penetrate into the kettle body assembly 116 and extend towards the bottom wall of the kettle body assembly 116. In order to ensure the heat preservation effect of the liquid heating container 100 and reduce the risk of scalding the user due to overheating of the outer surface of the container body 110 when the liquid heating container 100 boils water, the kettle body assembly 116 includes a housing 113 and an inner liner 114 disposed inside the housing 113. The inner liner 114 is nested inside the housing 113 and is spaced apart from the housing 113. Therefore, the guiding passage 112 is disposed between the housing 113 and the inner liner 114, so that there is no need to reserve extra space for the guiding passage 112, and the installation space is relatively large, which is helpful for the installation of the guiding passage 112 and for the guiding passage 112 to extend towards the bottom of the kettle body assembly 116.

[0062] In one embodiment, the lid assembly 120 further includes an upper lid 126 and a lower lid 127. The steam assembly 130 is disposed between the upper lid 126 and the lower lid 127. The lower lid 127 is provided with a plurality of steam inlet ports. The water outlet 121 and the steam inlet 132a are both communicated with the accommodating cavity 111 through the steam inlet ports. Specifically, the steam assembly 130 is disposed between the upper lid 126 and the lower lid 127, and the lower lid 127 is provided with a plurality of steam inlet ports. The water vapor generated in the accommodating cavity 111 first enters the steam inlet ports and then enters the steam passage 131, so that the lower lid 127 can further block the steam from entering the steam passage 131, thereby promoting the liquefaction of the steam.

[0063] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present invention.
