Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquid heating container technology, and in particular to a kettle lid and kettle that prevents spillage and steam leakage when tilted. Background Technology
[0002] A kettle consists of a lid and a body. The lid and body are typically fitted together with a tight seal to prevent hot water from overflowing and causing scalding if the kettle is accidentally tipped over. Additionally, modern kettles have a steam vent to allow air to escape from the water while it is boiling.
[0003] For example, utility model application CN202321557133.X provides a kettle, which includes a kettle body, a bottle cap, a valve assembly, and a switch assembly. The kettle body has a bottle cap seat, and the bottle cap can be fitted onto the bottle cap seat. The bottle cap has a mounting hole. The valve assembly is movably disposed in the mounting hole in a first direction, and the valve assembly includes a sealing part for sealing the mounting hole. The switch assembly is movably connected to the bottle cap in a second direction, perpendicular to the first direction. In this application, during the process of the switch assembly moving to the second position to unlock the bottle cap and bottle cap seat, the switch assembly can press the valve assembly downwards, causing the sealing part in the valve assembly to separate from the mounting hole. This allows the mounting hole to communicate with the interior space of the kettle, and the pressure inside the kettle can be released outwards through the mounting hole.
[0004] While the valve assembly is venting air, if the kettle accidentally tipes over, the mounting holes in the existing technology cannot be sealed in time, which can easily lead to the overflow of high-temperature steam and scald the user. Utility Model Content

[0038] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0039] Reference Figure 1 The kettle of this utility model includes a lid 10 for preventing spillage and steam leakage when tilted and a kettle body 20. The kettle body 20 is used to seal the kettle body 20. The inner walls of the lid 10 and the kettle body 20 are sealed together when tilted to prevent spillage and steam leakage.
[0040] Among them, reference Figure 1 and Figure 2The kettle lid 10, designed to prevent overflow and steam leakage when tilted, includes a lower lid 100, an upper lid 200, a valve cover 300, a steel ball 400, and a sealing plate 600. The lower lid 100 has a first steam hole 110 at its bottom and a water outlet channel 120 at its bottom. The water outlet channel 120 has an inlet 121 and an outlet 122, with an outlet spout 1221. The inlet 121 is located at the bottom of the lower lid 100. The upper lid 200 covers the upper end of the lower lid 100. An inner cavity 210 is provided between the upper lid 200 and the lower lid 100. A steam chamber 220 is located inside the inner cavity 210, and the steam chamber 220 has vent holes 311 and 321. The steam chamber 220 communicates with the first steam hole 110. A second steam hole 130 is provided, and the steam chamber 220 is connected to the water outlet channel 120 through the second steam hole 130. The lower part of the valve cover 300 and the lower cover 100 are fixedly connected, and an air chamber 310 is provided between the valve cover 300 and the lower cover 100. An air hole 311 is provided through the side wall of the valve cover 300. A limiting groove 312 is provided inside the valve cover 300, and the limiting groove 312 is correspondingly provided with the first steam hole 110. A steel ball 400 is built into the air chamber 310. A sealing plate 600 is movably connected to the water inlet 121 and is used to close or open the water inlet 121. The steel ball 400 can move in the air chamber 310 to be built into the limiting groove 312 or embedded in the first steam hole 110 and close the first steam hole 110.
[0041] When the kettle is placed normally, refer to Figure 2 Under its own weight and the constraints of the internal space of the air chamber 310, the steel ball 400 is positioned within the limiting groove 312. The first steam hole 110 is open, allowing steam inside the kettle to enter the steam chamber 220 through the first steam hole 110 and then exit through the vent 221, thereby triggering the steam bimetallic strip in the kettle body 20 and controlling the power-off of the entire kettle. Alternatively, steam can exit through the water outlet 122 via the water outlet channel 120 to control the internal air pressure. When the kettle's placement changes (e.g., the user actively tilts it, or the kettle is passively knocked over), refer to... Figure 4 The steel ball 400 moves within the air chamber 310 and can be inserted into and sealed by the first steam hole 110. This achieves automatic opening and closing of the first steam hole 110. Under normal conditions, it ensures steam discharge and prevents excessive pressure inside the kettle. Under special conditions, it seals the first steam hole 110 to prevent steam leakage and potential danger.
[0042] On the other hand, when water is needed, the sealing disc 600 opens the inlet 121, and the liquid inside the kettle enters the outlet channel 120 through the inlet 121, and then flows out from the spout 1221 of the outlet 122. When water is not needed, the sealing disc 600 closes the inlet 121 to prevent the liquid from flowing out. Specifically, during the process of pouring water from the kettle, the kettle is "actively" poured. At this time, the steel ball 400 blocks the first steam hole 110 to prevent steam from escaping from the outlet channel 120 and scalding the user during the pouring process.
[0043] In summary, when the kettle is tilted (actively or passively), the steel ball 400 located in the limiting groove 312 falls into the first steam hole 110 under the action of gravity, and blocks the first steam hole 110, preventing the hot steam in the kettle from being discharged to the outside through the first steam hole 110, the steam chamber 220 and the water outlet channel 120 and scalding the user.
[0044] In some embodiments, refer to Figure 4 A lid sealing ring 140 is fixedly connected to the lower side wall of the lower lid 100. The kettle body 20 is sealed to the lid 10 (which prevents overflow and steam leakage when tilted) through the lid sealing ring 140. The sealing effect of the lid sealing ring 140 enhances the sealing performance between the lid 10 (which prevents overflow and steam leakage when tilted) and the kettle body 20, further preventing liquid or steam from leaking from the connection between the lid 10 (which prevents overflow and steam leakage when tilted) and the kettle body 20.
[0045] In some embodiments, refer to Figure 3 and Figure 4 The valve cover 300 has multiple blades 320 arranged inside, spaced around the center of the valve cover 300, to form a through-hole 311 on the outer side of the valve cover 300. The inner side of the blades 320 is recessed to form a recess 321. The multiple recesses 321 cooperate to form a limiting groove 312 inside the valve cover 300. The structure of the blades 320 simultaneously realizes the construction of the through-hole 311 and the limiting groove 312, simplifying the structural design of the valve cover 300. The through-hole 311 allows hot steam inside the kettle body 20 to be discharged through the air chamber 310, the first steam hole 110, and the steam chamber 220.
[0046] Specifically, the steel ball 400 can only move within the space between the limiting groove 312 and the first steam hole 110, which is located directly above the limiting groove 312. The range of motion of the steel ball 400 is restricted to the space between the limiting groove 312 and the first steam hole 110. When the kettle is placed normally, the steel ball 400 is located within the limiting groove 312; when the kettle is tilted, because the first steam hole 110 is directly above the limiting groove 312, the steel ball 400 can move upward under the action of gravity and embed itself into the first steam hole 110, thereby improving the reliability and timeliness of the sealing.
[0047] As a further optimization of the above embodiments, refer to Figure 3 and Figure 4 In the vertical cross-section of the limiting groove 312, the upper part of the limiting groove 312 is cylindrical, and the lower part is conical. In the cross-section of the limiting groove 312, the diameter of the steel ball 400 is equal to the maximum diameter of the limiting groove 312, and the diameter of the steel ball 400 is larger than the diameter of the first steam hole 110. The upper cylindrical part of the limiting groove 312 can circumferentially limit the steel ball 400, and the lower conical part facilitates the steel ball 400 to be constrained in the limiting groove 312 under the action of gravity. The diameter of the steel ball 400 is equal to the maximum diameter of the limiting groove 312, so that the steel ball 400 can be stably placed in the limiting groove 312. And because the diameter of the steel ball 400 is larger than the diameter of the first steam hole 110, the first steam hole 110 can be effectively blocked, realizing the precise positioning and effective sealing of the steel ball 400.
[0048] It is worth mentioning that, referring to Figure 3 and Figure 4 A retaining ring 111 is also provided around the first steam hole 110 to cooperate with the limiting groove 312 to constrain the position of the steel ball 400 and prevent the steel ball 400 from falling out. The retaining ring 111 is fixedly connected to the valve cover 300.
[0049] In some embodiments, reference is made to Figure 4 The inner cavity 210 is fixedly connected to a steam cover 500. The steam cover 500, together with the lower cover 100 facing the upper cover 200, forms a steam chamber 220. A venting silicone 2211 is fixedly connected to the venting hole 221. The connection between the steam cover 500 and the lower cover 100 forms a closed steam chamber 220. After the steam inside the kettle enters the steam chamber 220 through the first steam hole 110, it is discharged from the venting hole 221. The venting silicone 2211 plays a certain role in buffering and sealing the discharged steam.
[0050] In some embodiments, refer to Figure 1 and Figure 4 The lower cover 100 is provided with a sliding channel 150. A sliding column 610 is fixedly connected to the upper part of the sealing disc 600. The sliding column 610 is built into the sliding channel 150 and the sliding column 610 and the sliding channel 150 are slidably connected. A drive mechanism 230 is movably connected to the upper cover 200. The drive mechanism 230 is fixedly connected to the end of the sliding column 610. The drive mechanism 230 is used to control the up and down movement of the sealing disc 600. When the drive mechanism 230 is activated, it drives the sliding column 610 connected to it to slide up and down in the sliding channel 150. The sliding column 610 drives the sealing disc 600 to move up and down synchronously. When the sealing disc 600 descends, the water inlet 121 is opened; when it rises, the water inlet 121 is closed.
[0051] Preferably, the drive mechanism 230 includes a pressing cover 231, a connecting member 232, and a spring. The pressing cover 231 is vertically and retractably embedded in the top of the upper cover 200. One end of the connecting member 232 is fixedly connected to the bottom of the pressing cover 231, and the other end is fixedly connected to the top of the sliding column 610. The spring is built into the upper cover 200, with one end fixedly connected to the bottom surface of the pressing cover 231 and the other end fixedly connected to the upper surface of the steam cover 500. The spring drives the pressing cover 231 to rise.
[0052] The top of the cover 200 is provided with a groove for inserting the press cover 231. The press cover 231 can move up and down in the groove. Through the elastic force of the spring, the press cover 231 always has an upward tendency to drive the sealing plate 600 to close the water inlet 121. The sealing plate 600 and the water inlet 121 will not separate when the kettle is tilted. The water inlet 121 can only be opened and the water in the kettle can be poured out when the user actively presses the sealing plate 600.
[0053] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
