Abstract
Description
Technical Field
[0001] The present invention relates to electric kettle technology, and in particular provides a tipping-proof leakage-proof structure for an electric kettle. Background Art
[0002] The electric kettle is a very common household appliance used to heat water to a boiling or desired temperature. It typically consists of a heating element, a control unit, and a spout located at the bottom of the kettle. However, while this type of kettle solves the problem of boiling water, it poses environmental and safety risks. For example, in terms of environmental protection, existing electric kettles lack a mechanism to prevent tipping and leakage. If the kettle is accidentally tipped over, the water in the kettle will spill everywhere, which does not meet environmental and hygienic requirements. If heated hot water spills, it poses a significant safety hazard. During this period, the industry developed tipping and leakage prevention structures, but most of them used electronic control and had complex structures. Electronics are not suitable for long-term high-temperature environments, and the complex structure is not conducive to reducing product costs. Summary of the Invention
[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a tipping-proof structure for an electric kettle, which solves the technical problem of heating and discharging steam and tipping without leaking water.
[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions, namely:

[0010] In this example, preferably, the kettle lid is adapted to the kettle body and includes a lid seat and a cover plate, the lid seat is molded and has reinforcing ribs, the seat plate is a component of the lid seat and corresponds to the bottom of the cover plate, a limiting groove is formed on the seat plate, and the discharge port is centered at the bottom of the limiting groove; the limiting groove is an open slot or is covered by reinforcing ribs to form a discharge port; the cover plate has an exhaust hole corresponding to the discharge port.
[0011] In this example, preferably, the limiting groove is formed with an opening corresponding to the inner bile hole toward the outside, and a retaining wall is formed inwardly opposite to the opening, and a positioning column is extended from the retaining wall toward the opening.
[0012] In this example, preferably, one end of the driven slider has a reverse bevel that matches the positive bevel, and the other end of the driven slider is formed with a plug-in column that can be inserted into one end of the compression spring. The other end of the compression spring is sleeved on the positioning column, and the seal is formed of silicone material and has a flat surface with a sealed discharge port.
[0013] In this example, it is preferred that the top rod of the top rod member is a long upright member adapted to fit in the gap.
[0014] In this example, preferably, the handle has a handle cavity, and the push rod of the push rod component is a bent component formed along with the change of the handle cavity structure.
[0015] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:
[0016] First, the leak-proof component covers the discharge port with a seal plane, ensuring that the water in the kettle will not leak out when the electric kettle is tipped over, avoiding environmental problems caused by leakage, and more importantly, avoiding safety problems caused by hot water leakage;
[0017] Secondly, the push rod component has a supporting portion protruding from the bottom of the kettle body and the supporting portion is retracted to the lower limit portion under the support of the kettle seat plane through the weight of the kettle body itself, so as to brake the push rod component to move upward and drive the sealing part of the leakage-proof component to move away from the discharge port to ensure exhaust during the heating process and avoid the safety hazard of steam overload.

Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other embodiments can be obtained based on these drawings without inventive work.
[0031] See Figure 1 and Figure 2 , Figure 1 A three-dimensional diagram of an electric kettle (or "electric water pot" or "electric thermos") is presented. Figure 2 Presented Figure 1 The cross-sectional view of the electric kettle is intended to fully demonstrate the design key points of the electric kettle's tipping-proof structure. The electric kettle in the figure includes a kettle body 10 and a kettle lid 20. The electric kettle's tipping-proof structure is configured in the kettle body 10 and the kettle lid 20, wherein:
[0032] The kettle body 10 includes an outer shell 11 and an inner liner 12, as well as a gap (not marked) formed between the outer shell 11 and the inner liner 12. In the gap near the handle 14, an upper limit portion (not marked) for the top rod component 13 of the anti-leakage structure for dumping and a lower limit portion 111 that passes through the bottom of the outer shell 11 (not marked) are formed. In this example, the electrical connector and the heating assembly are arranged in the interlayer 15 of the bottom of the outer shell and the bottom of the paired inner liner 12 (not marked). In this example, the top rod component 13 includes a top rod 131, a spring 132, a supporting portion 133 connected to the upper end of the top rod 131, and a supporting portion 134 that is movably extended / retracted from the lower limit portion 111, wherein: the supporting portion 133 (please refer to Figure 3 and Figure 4 ) is a structure that is integrally arranged with the ejector rod and is movable up and down and has a positive inclined surface 1331 inclined at 45 degrees in the forward direction, and the positive inclined surface 1331 is exposed in a corresponding hole (not marked) in the inner container 12;
[0033] The kettle lid 20 is adapted to the kettle body 10 and includes a lid seat 21 and a cover plate 22. The lid seat 21 is molded and has a seat plate 211. The seat plate includes reinforcing ribs (not marked) and a limiting groove 212 formed in combination with the reinforcing ribs. A steam discharge port 213 is formed in the center of the bottom of the limiting groove 212. The steam discharge inlet (i.e., "discharge port") 213 passes downward through the lid seat 21 and can be connected to the adapted inner tank cavity (not marked); the limiting groove 212 is an open slot upward or a steam discharge outlet (i.e., "discharge port") 214 formed by being covered by the reinforcing ribs, and the discharge port corresponds to the exhaust hole 221 on the cover plate 22; the limiting groove 212 forms an opening 215 toward the outside, and a retaining wall 216 facing inwardly opposite to the opening has a positioning column 217 protruding toward the opening. When the kettle lid 20 is adapted to the kettle body 10, the opening corresponds to the inner tank hole. In this example, the tipping anti-leakage structure also includes a anti-leakage component 23 adapted to the ejector component 13. The anti-leakage component 23 is arranged in the limiting groove 212 and includes a driven slider 231, a sealing member 232 and a compression spring 233 provided on the driven slider 231. One end of the driven slider 231 has a reverse inclined surface 2311 adapted to the positive inclined surface 1331 of the top holding portion; the other end of the driven slider 231 is formed with a plug-in column 2312 which can be inserted into one end of the compression spring 233. The other end of the compression spring 233 is sleeved on the positioning column 217 of the limiting groove. The sealing member 232 is made of silicone material and has a flat surface 2321 that seals and adapts to the discharge port 213. When the anti-leakage component 23 is in the compression spring 23 When extended, the sealing member plane 2321 covers the discharge port 213 to ensure that water in the kettle will not leak out when the electric kettle is tilted, thereby avoiding environmental problems caused by water leakage and, more importantly, safety problems caused by hot water leakage. When the electric kettle needs to be heated and kept warm, it needs to be adapted to the kettle seat 30. Under the action of the kettle body's own gravity, the abutting portion 134 of the kettle body 10 abuts against the flat surface 31 of the kettle seat 30 and retracts into the lower limit portion 111 to brake the push rod member 13 from shifting upward. At this time, the leakage-proof member 23 is driven by the push rod member 13 to move the sealing member 232 that seals the discharge port 213 away from the discharge port 213, thereby ensuring exhaust during the heating process and avoiding the safety hazard of steam overload.
[0034] In this embodiment, the top rod 131 of the top rod member 13 is a long upright member (such as Figure 2 shown).
[0035] In this embodiment, the top rod 131 of the top rod member 13 is a bending member (such as Figure 5 shown).
[0036] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant description of other embodiments.
[0037] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred embodiments of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention.
