Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] The purpose of this invention is to provide an anti-overflow pouring kettle to solve the problems existing in the prior art, reduce the amount of hot water overflowing when pouring, and improve the safety of users.
[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0030] Example 1
[0031] This embodiment provides an anti-overflow pour-over kettle, such as Figures 1-4As shown, the device includes a pot body 10 and a lid 20. The pot body 10 has a cavity and an upper opening communicating with the cavity. The lid 20 is capable of sealing and is fixedly installed at the upper opening. The cross-sectional shape of the pot body 10 in its normal placement state on the horizontal plane is circular. A long-tube spout 11 and a handle 12 are provided on the outer wall of the pot body 10, with the long-tube spout 11 and the handle 12 positioned opposite each other. The handle 12 is weighted so that the center of gravity of the pot body 10 is close to the handle 12, so that when the pot body 10 is tilted on the placement surface, The kettle body 10 has a handle 12 that can partially contact the placement surface, and the long tube spout 11 is tilted upwards, with the end opening of the long tube spout 11 located at the highest point of the long tube spout 11; the lid 20 is provided with a steam channel, and a steam valve is provided in the steam channel; the accommodating cavity of the kettle body 10 in the normal placement state can be kept in communication with the outside through the steam channel; and when the kettle body 10 is tilted, the steam valve can close the steam channel to prevent the liquid in the accommodating cavity from flowing out of the steam channel.
[0032] By weighting the handle 12, the center of gravity of the kettle body 10 is brought closer to the handle 12. When the kettle body 10 is tilted onto a flat surface, the handle 12 partially contacts the surface, causing the long spout 11 to tilt upwards, i.e., with the end opening facing upwards. This design reduces the amount of hot water overflowing from the long spout 11 during tilting. Because the lid 20 has a steam valve that seals the steam passage when the kettle body 10 is tilted, the kettle body 10 maintains pressure balance with the outside environment through the steam passage on the lid 20 before tilting. When the kettle body 10 is tilted, the sealed steam passage means that the cavity of the kettle body 10 is only connected to the outside environment through the long spout 11. The hot water inside the kettle body 10 is prevented from overflowing from the long spout 11 due to atmospheric pressure. The sealing of the steam passage on the lid 20 during tilting and the weighting of the handle 12 work together to reduce the amount of hot water overflowing when the kettle body 10 is tilted, improving user safety.
[0033] The following are the relevant settings for the lid 20:
[0034] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 and Figure 3As shown, the lid 20 has a venting cavity 21; the lower opening of the venting cavity 21 can communicate with the accommodating cavity, and the upper opening of the venting cavity 21 can communicate with the outside; the venting cavity 21 forms a steam passage; the steam valve includes a ball-shaped cavity 22 and a steel ball 23; the ball-shaped cavity 22 is fixedly disposed in the venting cavity 21; the lower opening of the ball-shaped cavity 22 communicates with the lower opening of the venting cavity 21; the steel ball 23 is located in the ball-shaped cavity 22, and the steel ball 23 can move along the steel ball The cavity 22 moves along its axis; a flow channel is provided circumferentially within the steel ball cavity 22, located within the steel ball 23; the upper opening of the steel ball cavity 22 is connected to the exhaust cavity 21; the accommodating cavity of the kettle body 10 in its normal placement state can be connected to the exhaust cavity 21 via the lower opening of the steel ball cavity 22, the flow channel, and the upper opening of the steel ball cavity 22; when the kettle body 10 is tilted, the steel ball 23 can roll to the upper opening of the steel ball cavity 22 and close the upper opening of the steel ball cavity 22.
[0035] Specifically, multiple support plates 221 are fixed on the inner circumferential side wall of the steel ball cavity 22. There is a gap between each pair of adjacent support plates 221, which is a section of the flow channel. When the kettle body 10 is in the normal placement state and the steel ball 23 on the kettle lid 20 is in the lowest position, the lower opening of the steel ball cavity 22 is still in communication with the connecting channel.
[0036] The following are the settings instructions for the pot body 10:
[0037] In the optional solutions of this embodiment, the preferred method is to increase the weight of the handle 12 by increasing the material density of the handle 12, increasing the volume of the handle 12 to increase the weight of the handle 12, or adding a counterweight 121 inside the handle 12 to increase the weight of the handle 12.
[0038] Specifically, the weighting settings for handle 12 include, but are not limited to, the weighting methods mentioned above.
[0039] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 and Figure 2 As shown, when the pot body 10 is placed normally on the flat surface, the outer diameter of the upper end of the pot body 10 is smaller than the outer diameter of the lower end of the pot body 10, and the outer wall of the upper end of the pot body 10 is smoothly connected to the outer wall of the lower end of the pot body 10; and the weighted arrangement of the handle 12 makes the center of gravity of the pot body 10 closer to the side of the upper end of the pot body 10 with the handle 12.
[0040] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 As shown, a steam flow channel 15 is fixedly provided on the outer wall of the kettle body 10. The upper opening of the steam flow channel 15 is connected to the exhaust cavity 21, and the lower end of the steam flow channel 15 is connected to a temperature sensing system.
[0041] Specifically, a protective cover 16 is provided on the outer side of the steam flow channel 15 on the outer side wall of the kettle body 10, and the handle 12 is fixed on the protective cover 16.
[0042] Specifically, the temperature sensing system is used to link with the heating control switch. When the desired temperature is reached, it can automatically disconnect the heating control switch. For example, it can be a steam switch, which can turn off the heating function when the set temperature is reached. In addition to the steam switch, the temperature sensing system can also include a display screen and a temperature sensor. The temperature sensor is used to measure the steam temperature, and the display screen is used to display the measured steam temperature. When the steam temperature measured by the temperature sensor reaches the set temperature, it can link with the steam switch to turn off the heating function.
[0043] Specifically, the anti-overflow pour-over kettle of this embodiment has a small spout version and a large spout version; when it is the small spout version, because the diameter of the long tube spout 11 is small, the cross-sectional area of the hole of the long tube spout 11 is ≤38mm². 2 In this case, the end opening of the long-tube spout 11 does not need to be equipped with a flow limiting device; when it is a large spout version, since the diameter of the long-tube spout 11 is also large, the end opening of the long-tube spout 11 is equipped with a flow limiting device.
[0044] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 2 As shown, a flow limiting device is provided at the end opening of the long tube spout 11. The flow limiting device is used to reduce the end opening of the long tube spout 11.
[0045] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 2 As shown, the flow limiting device is a baffle 111, which is fixedly installed at the end opening of the long tube spout 11 and covers part of the end opening of the long tube spout 11.
[0046] Specifically, the flow limiting device can be a baffle 111 fixed to the end opening of the long-tube spout 11, or a half-baffle set at the end opening of the long-tube spout 11. The half-baffle is rotatably set at the end opening of the long-tube spout 11, and the half-baffle can cover part of the opening of the long-tube spout 11 by magnetic adsorption. During normal use, it can be released from adsorption by the water flow impact inside the long-tube spout 11. In order to improve the ability of the half-baffle to be correctly magnetically adsorbed at the opening of the long-tube spout 11 rather than on the outer wall of the long-tube spout 11 in the opposite direction, a limiting structure, such as a limiting rod, can be set at the rotation position of the half-baffle to limit the half-baffle from rotating in the opposite direction around its rotation axis and adsorbing on the outer wall of the long-tube spout 11.
[0047] The following are the relevant specifications regarding the connection structure between the pot body 10 and the pot lid 20:
[0048] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 and Figure 3 As shown, a receiving protrusion 13 is provided in the upper opening of the pot body 10; a receiving ring surface is provided on the pot lid 20. When the pot lid 20 is closed on the upper opening of the pot body 10, the receiving ring surface is located on the receiving protrusion 13.
[0049] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 , Figure 3 and Figure 4 As shown, a sealing ring 14 (made of rubber) that can elastically deform is fixedly installed inside the upper opening of the kettle body 10. The inner diameter of the sealing ring 14 is smaller than the lower inner diameter of the kettle lid 20; and the outer diameter of the sealing ring 14 is larger than the lower inner diameter of the kettle lid 20. When the kettle lid 20 is sealed and fixed in the upper opening, the lower end of the kettle lid 20 abuts against the upper end of the sealing ring 14 (the part of the sealing ring 14 that is used to cooperate with the kettle lid 20 is inclined, and the lower end of the kettle lid 20 is pressed against the upper surface of the sealing ring 14).
[0050] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 , Figure 3 and Figure 4 As shown, two opposing telescopic grooves are provided on the side wall of the lid 20, and a telescopic locking rod 24 is slidably installed in each telescopic groove; two opposing locking grooves are provided on the inner side wall of the upper opening of the pot body 10; each locking groove corresponds to a telescopic locking rod 24, and the telescopic locking rod 24 can be inserted into the locking groove to achieve a fixed connection between the lid 20 and the pot body 10.
[0051] Specifically, the ends of the two telescopic locking rods 24 near the axis of the lid 20 are the control ends 241. A spring 25 is provided between the two control ends 241. In the natural state, the spring 25 keeps the two telescopic locking rods 24 in the extended state. The upper end of the lid 20 is provided with a resting groove 26 and a control port communicating with the resting groove 26. The control end 241 of the telescopic locking rod 24 can penetrate into the resting groove 26 through the control port. The operator's fingers can be located in the resting groove 26 and squeeze the control end 241 in the opposite direction to retract the telescopic locking rod 24, thereby realizing the disconnection of the lid 20 from the body 10.
[0052] Regarding other relevant explanations:
[0053] Specifically, the spill-proof kettle provided in this embodiment meets the safety testing standards of Japan, meaning that under the required testing conditions, the amount of hot water overflowing meets the results required by the testing standards. (For example, the amount of water overflowing within ten seconds after pouring should not exceed fifty grams.)
[0054] Specifically, a heating base 30 is also provided. The heating base 30 is used in conjunction with the kettle body 10. The heating base 30 is used to heat the water in the kettle body 10. This is existing technology and will not be described in detail here.
[0055] Specifically, the heating base 30 is circular, and when the heating base 30, the kettle body 10, the lid 20, etc. are tilted together, the purpose of reducing the amount of water overflow can also be achieved.
[0056] Specifically, the other related structures not mentioned in the anti-overflow pour-over kettle provided in this embodiment are all existing technologies, such as the heating component at the bottom of the kettle body 10 for cooperating with the heating base 30, etc., which will not be described in detail here.
[0057] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
