Abstract
Description
Technical Field
[0001] This utility model relates to the field of kitchen cooking utensils, and in particular to a steam diversion lid that prevents overflow. Background Technology
[0002] A pot lid is one of the core components of a cooking container. Its main function is to create a sealed or semi-sealed space by covering the opening of the pot, thereby improving the heat efficiency inside the pot, accelerating the cooking of food, and reducing moisture evaporation. Traditional pot lids are mostly made of metal, glass, or heat-resistant plastic. Their structure typically includes a top cover body, an edge sealing ring, and a handle, achieving heat preservation and steam control through physical barriers.
[0003] To prevent excessive pressure buildup inside the pot, current pot lids generally have a single small vent. These vents allow a small amount of steam to escape continuously, maintaining pressure balance inside the pot. Some designs add silicone valve plates or gravity valves at the vents, attempting to close them at normal pressure to reduce heat loss, and only passively open them when the pressure increases.
[0004] Despite its simple pore structure, it has significant shortcomings. First, the pore size is mismatched with the steam flow rate: the micro-pores cannot handle the high-intensity steam flow generated by high-power heating or easily foaming foods. When the steam generation per unit time exceeds the pore discharge capacity, steam accumulates rapidly in the pot, pushing up the liquid level and causing overflow. It cannot fundamentally solve the overflow prevention requirements in high-steam scenarios, and a new structure that actively diverts steam and dynamically adapts to the steam load is urgently needed. Utility Model Content
[0005] The technical problem to be solved by this utility model is that the aperture restricts the exhaust, and a steam diversion pot lid that prevents overflow is provided to solve the above-mentioned problem.

The side of the first guide hood is connected to the guide block, and the first guide hood is spliced with the second guide hood through the guide block. The top and bottom sides of the first and second guide hoods are both connected to the connecting blocks. The fixing screws are fixedly connected to the first and second guide hoods through the connecting blocks. One end of the first and second guide hoods is slidably connected to the mounting ring. The mounting ring is fixed to the first and second guide hoods by several fixing screws. The other end of the second guide hood is provided with a pressurizing component to prevent gas overflow.
[0007] A further preferred embodiment of this utility model is as follows: the pressurizing component includes a base, a torsion spring and a cover plate. The top of the second flow guide port is connected to the base. One end of the cover plate is rotatably connected to the base via a rotating shaft. The other end of the cover plate is closed to the second flow guide port via a circular plate. Both ends of the rotating shaft of the cover plate are fitted with torsion springs. One end of the torsion spring is connected to the base and the other end is connected to the cover plate.
[0008] A further preferred embodiment of this utility model is as follows: it also includes a limiting ring, filter cotton, a fixed shell and a collection box. The bottom of the second guide hood is connected to the fixed shell, the second guide hood is in communication with the fixed shell, the collection box is slidably connected inside the fixed shell, the limiting ring is slidably connected inside the port of the second guide hood, the filter cotton is provided inside the limiting ring, and the limiting ring is located at the top of the fixed shell.
[0009] A further preferred embodiment of this utility model is that it also includes a protective pad, and a protective pad is connected to the end of each fixing screw.
[0010] A further preferred embodiment of this utility model is: it also includes a magnet and an iron block, the magnet is connected inside the fixed shell, and the iron block is connected to one end of the collection box inserted into the fixed shell, and the magnet and the iron block are magnetically connected.

[0013] A further preferred embodiment of this utility model is: it also includes a sealing gasket, the outer ring of the guide block is fitted with a sealing gasket, and the first guide shield and the second guide shield are squeezed together with the sealing gasket.
[0014] Compared with existing technologies, the advantages of this invention are: The handle-type overflow pipe, formed by the splicing of the first and second guide hoods, creates a steam diversion channel with a significantly large cross-section, transforming the high-pressure steam from traditional small-hole injection to a stable laminar flow, resulting in a substantial increase in steam flux and completely eliminating the risk of overflow during cooking; the cover opens to release pressure when steam accumulates and automatically closes when the pressure drops. By replacing torsion springs with different torques, the pressure thresholds for stewing, porridge making, and other scenarios can be flexibly matched, significantly reducing heat loss while preventing overflow.

Detailed Implementation
[0024] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.
[0025] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.
[0026] This embodiment mainly describes the structure of the pot lid, as follows:
[0027] A steam diversion lid to prevent overflow, such as Figures 1-7 As shown, the device includes a pot lid 1, a mounting ring 2, a first flow guide 3, a second flow guide 4, a guide block 5, a connecting block 6, fixing screws 7, and a pressurizing component. The top of the pot lid 1 is connected to the mounting ring 2, which is threaded with several fixing screws 7. The side of the first flow guide 3 is connected to the guide block 5. The first flow guide 3 is spliced with the second flow guide 4 through the guide block 5 to form a round tube pot lid handle. The top and bottom sides of the first flow guide 3 and the second flow guide 4 are both connected to the connecting blocks 6. The fixing screws 7 are fixedly connected to the first flow guide 3 and the second flow guide 4 through the connecting blocks 6. One end of the first flow guide 3 and the second flow guide 4 are slidably connected to the mounting ring 2. The mounting ring 2 is fixed to the first flow guide 3 and the second flow guide 4 by several fixing screws 7. The other end of the second flow guide 4 is provided with a pressurizing component to prevent gas overflow.
[0028] like Figure 2 and Figure 6 As shown, the pressurization assembly includes a base 12, a torsion spring 13, and a cover plate 14. The base 12 is connected to the top of the second flow guide 4 port. One end of the cover plate 14 is rotatably connected to the base 12 via a rotating shaft. The other end of the cover plate 14 is closed to the second flow guide 4 port via a circular plate. Torsion springs 13 are sleeved on both ends of the rotating shaft of the cover plate 14. One end of the torsion spring 13 is connected to the base 12, and the other end is connected to the cover plate 14.
[0029] like Figure 4 and Figure 5 As shown, it also includes a limiting ring 8, a filter cotton 9, a fixed housing 10, and a collection box 11. The bottom of the second guide shroud 4 is connected to the fixed housing 10, and the second guide shroud 4 communicates with the fixed housing 10. The collection box 11 is slidably connected inside the fixed housing 10. The limiting ring 8 is slidably connected inside the port of the second guide shroud 4. The filter cotton 9 is provided inside the limiting ring 8, and the limiting ring 8 is located at the top of the fixed housing 10.
[0030] like Figure 1 and Figure 2 As shown, it also includes a protective pad 15, and each fixing screw 7 has a protective pad 15 connected to its end.
[0031] like Figure 5 As shown, it also includes a magnet 16 and an iron block 17. The magnet 16 is connected inside the fixed housing 10, and the iron block 17 is connected to one end of the collection box 11 inserted into the fixed housing 10. The magnet 16 attracts the iron block 17 on the collection box 11.
[0032] like Figure 5 As shown, it also includes an observation window 18, and the collection box 11 and the fixed outer shell 10 are respectively provided with observation windows 18 made of transparent material.
[0033] like Figure 7As shown, it also includes a guide ring 19. The top of the inner ring of the mounting ring 2 is connected to the guide ring 19, and the first guide shield 3 and the second guide shield 4 are slidably connected to the guide ring 19.
[0034] like Figure 3 As shown, it also includes a sealing gasket 20. The outer ring of the guide block 5 is fitted with a sealing gasket 20, and the first guide shield 3 and the second guide shield 4 are pressed together with the sealing gasket 20.
[0035] After the lid 1 covers the pot, the large amount of steam generated inside the pot first enters the composite channel formed by the first guide shroud 3 and the second guide shroud 4 through the mounting ring 2. As the steam flows through the second guide shroud 4, it continuously impacts the filter cotton 9 inside the limiting ring 8. The water vapor condenses into tiny water droplets due to the fiber barrier. Under the action of gravity, the water droplets aggregate along the surface of the filter cotton 9 and drip down into the fixed outer shell 10 below. This process continuously separates the moisture in the steam, preventing water mist from splashing out of the outlet of the second guide shroud 4 and endangering electrical equipment. The operator can monitor the liquid level in the collection box 11 in real time through the transparent observation window 18. When the liquid level is close to the upper limit, the collection box 11 can be directly pulled out and the liquid poured out.
[0036] During the assembly and installation of the pot lid handle, the worker first places the sealing gasket 20 on the outer edge of the guide block 5, and then precisely inserts the guide block 5 into the pre-set groove on the side wall of the second guide shroud 4; at this time, the first guide shroud 3 and the second guide shroud 4 are physically connected through the guide block 5, and the sealing gasket 20 is compressed to form a sealed interlayer. The assembly is pushed into the mounting ring 2 along the inclined surface of the guide ring 19, and the fixing screw 7 is tightened to press the connecting block 6 to fix the guide shroud. Finally, the protective gasket 15 is embedded into the groove at the end of the fixing screw 7 to form an oil-proof sealing barrier. The entire process relies on the self-positioning design of the inclined surface of the guide ring 19 to achieve rapid blind assembly.
[0037] Before steam exits from the end of the second guide hood 4, it must overcome the closing force exerted by the torsion spring 13 on the lid 14. When the pressure inside the pot rises to a set threshold, the steam pressure pushes the lid 14 to rotate around the base 12 axis, compressing the torsion spring 13 to open the exhaust channel; when the pressure drops, the torsion spring 13 automatically rebounds to close the lid 14. Operators can replace the torsion spring 13 with different torque coefficients according to the cooking intensity requirements to achieve dynamic pressure adjustment.
[0038] When the collection box 11 is inserted into the fixed outer shell 10, the iron block 17 inside it automatically attracts and locks with the magnet 16 at the bottom of the outer shell, ensuring that the collection box 11 does not shift when the pot lid 1 moves or tilts. When the filter cotton 9 becomes saturated and fails due to long-term use, the staff uses tweezers to hold the edge of the limiting ring 8 and slide it out from the second guide cover 4. After replacing the filter cotton 9, it is pushed back in to reset. The magnetic fixing and modular design significantly improve maintenance efficiency.
