[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0028] like Figures 1 to 5 The illustrated pressure-relieving kettle lid, designed for easy disassembly and cleaning, comprises a lid body 1 that can be mounted on an electric kettle, with a pressure relief valve assembly detachably connected thereto. This pressure relief valve assembly not only effectively relieves excess pressure within the kettle, preventing potential safety hazards caused by excessive pressure, but its detachable design also greatly enhances cleaning convenience. If scale, food residue, or other impurities accumulate within the pressure relief valve assembly during use, the user can simply remove it for thorough cleaning.

[0029] More specifically, the top surface of the lid body 1 is provided with an outer plate 4 that blocks the pressure relief valve assembly, and a quick-release structure is provided between the outer plate 4 and the lid body 1 for detachable connection between the two. In other words, removing the outer plate 4 exposes the pressure relief valve on the valve seat plate 3, allowing for disassembly, cleaning, and maintenance of the pressure relief valve.

[0030] The lid body 1 is designed with open ends at both ends, and features an annular mounting base 2 within it, providing a foundation for mounting the pressure relief valve assembly. The core component of this pressure relief valve assembly is a valve seat plate 3, mounted within the mounting base 2. This seat plate incorporates a split-type pressure relief valve (described in detail later). Above this valve seat plate 3 is an outer plate 4, which is provided with a first vent 41.

[0031] To enhance user convenience, a quick-release mechanism (described later) is used to connect the outer plate 4 to the lid body 1. This allows users to easily remove the outer plate 4, allowing for thorough cleaning and maintenance of the lid body 1's internal structure, ensuring the device remains in good working condition and preventing impurities from accumulating inside and affecting performance.

[0032] Two split-type pressure relief valves, namely the first pressure relief valve and the second pressure relief valve, are integrated on the valve seat plate 3. Although the present invention cites an embodiment with two pressure relief valves, if only one pressure relief valve is integrated on the valve seat plate 3, it should also be within the scope of protection of the present invention.

[0033] The first pressure relief valve is designed to include a first pressure relief hole 31 connecting the inside and outside. A first valve core 32, which opens outward in one direction, is located within the hole. To ensure the effective operation of the valve core, a first return spring 33 is installed on the outside of the first valve core 32, which automatically resets the valve core after opening. Notably, the upper end of the first return spring 33 directly abuts the outer plate 4. This design allows for easy removal of the first return spring 33 and the first valve core 32 after removing the outer plate 4, facilitating routine maintenance and cleaning.

[0034] The second pressure relief valve's construction is similar to the first. The valve seat plate 3 features a second pressure relief hole 34, connecting the inside and outside. Within this hole lies a second valve core 35, which similarly opens outward in one direction. A second return spring 36 is attached to the outside of the hole to ensure proper operation. The upper end of the second return spring 36 also abuts against the outer plate 4. This design, consistent with the first pressure relief valve, allows for easy removal of the second return spring 36 and the second valve core 35 after removing the outer plate 4, further simplifying cleaning and maintenance.

[0035] Through this ingenious structural design, the pressure relief system of the split electric kettle not only improves the safety of use, but also greatly enhances the convenience of cleaning and maintenance.

[0036] Furthermore, there is a significant difference in the elastic force between the second return spring 36 and the first return spring 33. Specifically, the elastic force of the second return spring 36 is greater than the elastic force of the first return spring 33. This design takes into account the pressure variations in the electric kettle under different operating conditions, ensuring that it can effectively cope with changes in internal pressure in various situations.

[0037] When the pressure inside the kettle is low, only the first pressure relief valve activates to relieve pressure, ensuring safe operation of the device under low pressure. When the temperature and pressure inside the kettle rise to a certain threshold, the first pressure relief valve can effectively relieve some of the pressure. However, if the pressure increases too quickly, the pressure relief speed of the first pressure relief valve may not be sufficient to cope with the rapidly rising pressure. At this time, when the internal pressure reaches a preset critical point, the second pressure relief valve will automatically activate and open rapidly to provide additional pressure relief. At this time, the two pressure relief valves work simultaneously and synergistically, significantly increasing the pressure relief speed. This dual pressure relief design not only enhances the safety of the electric kettle, but also effectively reduces the risk of overpressure.

[0038] The quick-release structure is specifically designed as follows: it primarily comprises a first buckle 42 provided on the outer plate 4, and a press buckle 5 rotatably connected to the lid body 1. The press buckle engages with the first buckle 42, thereby securing the outer plate 4. This design not only ensures the outer plate remains secure during use but also facilitates subsequent disassembly.

[0039] Furthermore, the first fastening portion 42 is designed with a finger-accessible release space 421. This space allows the user to easily insert a finger into the release space when removing the outer panel 4, thereby more conveniently operating the buckle 5 and achieving quick release. This user-friendly design enhances the overall user experience, allowing users to quickly complete disassembly without the need for additional tools.

[0040] Furthermore, the quick-release structure includes a second snap-in location 43 extending downwardly from the outer panel 4. This second snap-in location 43 engages with the third snap-in location 21 on the mounting base 2, further enhancing the stability and safety of the outer panel 4. When the outer panel 4 is connected to the second snap-in location 43 and the third snap-in location 21, the entire assembly becomes more compact, ensuring that it will not become loose during use due to vibration or other factors.

[0041] This quick-release structure improves the efficiency of disassembly and installation of the outer plate 4, while ensuring the safety and stability of the equipment during use, making it easier for users to use and maintain it daily.

[0042] It is worth noting that the valve seat plate 3 is also easily removable. It is detachably mounted in the mounting base 2, which provides great convenience for users, making it easy to disassemble, clean, and maintain the valve seat plate 3. This detachable structure allows users to easily clean the internal components of the valve seat plate, ensuring that the device always maintains optimal condition during use and reducing performance degradation caused by accumulated impurities.

[0043] Furthermore, the bottom of the inner sidewall of the mounting base 2 is provided with an upwardly opening annular mounting groove 22. This groove provides a foundation for the installation of the valve seat plate 3, allowing it to be securely fixed within the mounting base. A cylindrical support sleeve 37 is provided around the periphery of the valve seat plate 3. The support sleeve 37 is inserted downwardly into the mounting groove 22, forming a tight fit.

[0044] To further enhance sealing performance, a sealing ring 38 is provided between the outer wall of the support sleeve 37 and the inner wall of the valve seat plate 3 to seal the two. The sealing ring 38 effectively prevents internal gas leakage, ensuring that the equipment can still operate safely and stably under high-pressure working environments.

[0045] More specifically, the lid body 1 is provided with an inner plate 6 positioned below the valve seat plate 3. This inner plate 6 is provided with a second vent 61. This second vent 61 serves to ventilate and block impurities. High-pressure gas within the kettle first passes through the second vent 61, then through the pressure relief holes (either the first pressure relief hole 31 or the second pressure relief hole 34), and finally exits through the first vent 41.

[0046] More specifically, the first pressure relief hole 31 is horizontally staggered from the first vent hole 41 and the second vent hole 61, and the second pressure relief hole 34 is also horizontally staggered from the first vent hole 41 and the second vent hole 61. This horizontal staggered layout ensures that the steam must flow through a tortuous path when it is discharged. This not only increases the flow time of the steam, allowing more heat to dissipate and effectively lowering the temperature of the steam, but also increases the contact area between the steam and the inner wall of the kettle, thereby further reducing the temperature of the steam released to the outside. In addition, this turbulent effect also helps to reduce direct heat loss inside the travel kettle, improving the energy efficiency of boiling water.
