Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, specifically to an anti-splash device, a container lid with the anti-splash device, and a cooking container with the container lid. Background Technology

[0002] During cooking, especially when making porridge or stewing soup, existing cooking containers (rice cookers, pressure cookers) can cause problems. Nutrients such as protein, fat, or starch in the food easily combine with bubbles in boiling water, forming a protective film on the bubble walls. This increases the overall strength of the bubbles, causing them to accumulate above the liquid surface. When the number and volume of these bubbles reach a certain level, they can overflow the cooking container, carrying liquid and solid particles (such as rice grains or food scraps), creating a "bubble-liquid-solid" mixture. Driven by the increased internal pressure, this mixture can splash outwards, potentially causing injury or making cleaning the stovetop difficult. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide an anti-splash device, a container lid with the anti-splash device, and a cooking container with the container lid, so as to solve the problem that liquid is easily splashed during cooking in the prior art.

[0004] According to a first aspect of the present invention, a splash-proof device is provided, wherein the splash-proof device includes a housing and a plurality of filler particles, the housing has an internal cavity, and the housing is provided with a through hole for communicating the cavity with the outside; the plurality of filler particles are rotatably disposed in the cavity.

[0005] According to the anti-splash device provided in this embodiment, when the anti-splash device is applied to a cooking container, the mixed gas in the cooking chamber of the cooking container will push the bubbles through the receiving chamber of the anti-splash device. At this time, each filling particle can roll under the pressure of the mixed gas to break the bubbles. At the same time, the pressure has been released to a certain extent during this process. Under these circumstances, most of the liquid and solid particles carried in the bubbles will flow back into the cooking chamber of the cooking container in time under the action of their own gravity, which can prevent them from continuing to splash out under the push of the next surge of gas. Thus, the anti-splash device of this invention can not only prevent the liquid and solid particles carried in the bubbles from splashing and causing harm to the human body, but also greatly reduce the trouble of cleaning the stove.

[0006] In some embodiments, the plurality of filler particles are stacked in multiple layers in the height direction of the anti-splash device, which facilitates the formation of a multi-layered bubble-breaking structure, increases the number of collisions between the bubbles and the multiple filler particles, and thus further reduces splashing.

[0007] In some embodiments, the filling particles in the upper layer are arranged alternately with the filling particles in the lower layer.

[0008] In these embodiments, by staggering the filling particles in the upper layer with those in the lower layer, a non-uniform gap pore gradient can be formed to further increase the number of collisions between bubbles and particles, thereby reducing splashing to some extent.

[0009] In some embodiments, the anti-splash device further includes a partition mesh plate, which is disposed at intervals in the receiving cavity and divides the receiving cavity into a plurality of sub-cavities in the height direction of the anti-splash device. The plurality of filling particles are respectively disposed in the corresponding sub-cavities, and the filling particles in each sub-cavity roll in the corresponding sub-cavity.

[0010] In this embodiment, the use of a separator mesh facilitates the arrangement of multiple layers of filler particles, enabling the multi-stage bubble-breaking structure to minimize the impact of air bubbles generated during cooking. Furthermore, the separator mesh effectively separates the filler particles between layers, preventing interference during their movement.

[0011] In some embodiments, the height of the sub-cavity is greater than the size of the filling particles, which facilitates the rolling of the filling particles in each sub-cavity under the pressure of external gas, thus preparing for splash prevention.

[0012] In some embodiments, the height of the sub-cavity is 1.1 to 3 times the size of the filling particles. This achieves the purpose of allowing the filling particles in each sub-cavity to roll within the corresponding sub-cavity under the pressure of external gas, while minimizing the overall height of the anti-splash device, thus making it easy to apply to the size requirements of the container lid of a cooking container.

[0013] In some embodiments, the filler particles are inorganic non-metallic particles or metallic particles. The diverse types of filler particles enable the manufacture of various types of anti-splash devices, expanding the types of cooking containers that can utilize anti-splash devices and allowing for tailored configurations based on actual needs.

[0014] In some embodiments, the inorganic non-metallic particles are molecular sieve particles; wherein the particle size of the molecular sieve particles is 1.5 mm to 3.0 mm. Molecular sieve particles of this size can provide a suitable specific surface area, which can increase the probability of contact with air bubbles, thereby increasing the possibility of breaking the air bubbles and suppressing splashing of the cooking container during use.

[0015] In some embodiments, the pore size of the molecular sieve particles is The appropriate pore size of molecular sieve particles can ensure gas flow performance, thereby optimizing the gas flow performance of the anti-splash device and improving its anti-splash performance.

[0016] In some embodiments, the molecular sieve particles include one of aluminosilicate molecular sieves, titanium silicate molecular sieves, and phosphorus aluminosilicate molecular sieves, which can diversify the types of molecular sieve particles used as filler particles, enabling the manufacture of various types of anti-splash devices, thereby expanding the types of cooking containers that can be used with anti-splash devices and allowing for preferential settings based on actual needs.

[0017] In some embodiments, the filler particles have a nanoscale rough surface, thus enabling them to mechanically puncture air bubbles using their surface shape to further enhance splash protection.

[0018] According to a second aspect of the present invention, a container lid is provided, wherein the container lid includes a lid body and a splash-proof device as described above, the lid body is provided with an exhaust port, and the splash-proof device is installed in the exhaust port.

[0019] According to the container lid of this utility model, the mixed gas in the cooking chamber of the cooking container will push the bubbles through the receiving chamber of the anti-splash device. At this time, each filling particle can roll under the pressure of the mixed gas to break the bubbles. At the same time, the pressure has been released to a certain extent during this process. Under these circumstances, most of the liquid and solid particles carried in the bubbles will flow back into the cooking chamber of the cooking container in time under the action of their own gravity, which can prevent them from continuing to splash outward under the push of the next surge of gas. Thus, the anti-splash device of this utility model can not only prevent the liquid and solid particles carried in the bubbles from splashing and causing harm to the human body, but also greatly reduce the trouble of cleaning the stove.

[0020] In some embodiments, the container lid further includes a pressure regulating valve disposed at the outlet of the exhaust port, and an anti-splash device disposed at the inlet of the exhaust port.

[0021] In these embodiments, during the use of the cooking container, because the anti-splash device is installed at the air inlet of the exhaust port, it can prevent the exhaust port of the cooking container from being blocked by solid particles or other foreign objects during cooking, thus avoiding poor exhaust, safety issues, or splashing problems. Since the pressure regulating valve is located at the air outlet of the exhaust port, the reliability of the pressure regulating valve's pressure regulation is ensured, thereby guaranteeing the normal cooking function of the cooking container and simultaneously improving safety during use.

[0022] In some embodiments, an exhaust pipe is provided in the exhaust port, the exhaust pipe including an air inlet section near the inner side of the cover body and an exhaust section near the outer side of the cover body, the anti-splash device is connected to the air inlet section of the exhaust pipe, and the pressure regulating valve is connected to the exhaust section of the exhaust pipe.

[0023] In these embodiments, by providing an exhaust pipe in the exhaust port to connect the anti-splash device and the pressure regulating valve, not only is connection and installation easier, but maintainability is also improved.

[0024] According to a third aspect of the present invention, a cooking container is provided, wherein the cooking container includes a container body and a container lid connected to the container body, and the container lid is the container lid described above. Attached Figure Description

[0042] Furthermore, in the description of the examples, detailed descriptions of well-known related components or functions will be omitted when it is believed that such detailed descriptions would lead to a vague interpretation of the present invention.

[0043] Existing cooking containers (rice cookers, pressure cookers) often cause food in the cooking cavity to become viscous or produce bubbles when heated. These bubbles, as they overflow, often carry liquid and solid particles (such as rice grains and food scraps), forming a "bubble-liquid-solid" mixture. Driven by internal pressure, this mixture can continuously splash outwards, potentially causing injury or making cleaning the stovetop difficult. Furthermore, as the mixture cools, it can partially block the vent, preventing steam from escaping properly the next time the cooking container is used. This increases the internal pressure within the cooking cavity, further exacerbating splashing or posing safety hazards, thus causing inconvenience.

[0044] The following will combine Figures 1 to 6 This invention introduces the anti-splash device provided by the embodiments of the present invention.

[0045] According to a first aspect of this utility model, a splash-proof device is provided for a cooking container, specifically for use in the container lid 100 of the cooking container. Figures 1 to 3As shown, the anti-splash device 10 includes a housing 11 and a plurality of filler particles 12. The housing 11 has a receiving cavity 111 inside, and the housing 11 is provided with a through hole 112 that allows the receiving cavity 111 to communicate with the outside. The plurality of filler particles 12 are rotatably disposed in the receiving cavity 111.

[0046] According to the anti-splash device provided in this embodiment, when the anti-splash device is applied to a cooking container, the mixed gas in the cooking chamber of the cooking container (which is an external gas relative to the anti-splash device) will push the bubbles through the receiving chamber 111 of the anti-splash device. At this time, each filling particle 12 can roll under the pressure of the external gas to break the bubbles. At the same time, the pressure has been released to a certain extent during this process. Under these circumstances, most of the liquid and solid particles carried in the bubbles will flow back to the cooking chamber of the cooking container in time under the action of their own gravity, which can prevent them from continuing to splash outward under the push of the next surge of gas. Thus, the anti-splash device of this invention can not only prevent the liquid and solid particles carried in the bubbles from splashing and causing harm to the human body, but also greatly reduce the trouble of cleaning the stove.

[0047] According to some embodiments of this application, a plurality of filler particles 12 can be arranged as a single layer in the receiving cavity 111. In this case, the plurality of filler particles 12 are evenly spread on the bottom wall of the receiving cavity 111 and have a certain spacing between them that allows them to roll independently, so that each filler particle 12 can move independently under the pressure of external gas. As a specific example, the gap between adjacent filler particles 12 is a millimeter-level gap and is smaller than the particle size of the filler particles 12. More specifically, the particle size of the filler particles 12 is 1.5 mm to 3.0 mm, and the gap between adjacent filler particles 12 is 1.0 mm to 2.5 mm.

[0048] According to other embodiments of this application, the multiple filler particles 12 can also be configured as multiple layers, and the filler particles 12 in each layer can roll together under the pressure of external gas to break the bubbles. In these embodiments, the multiple filler particles 12 roll together to form a bubble disturbance layer or a bubble breaking layer, thereby breaking the bubbles to reduce splashing.

[0049] According to some embodiments of this application, multiple filler particles 12 are stacked in multiple layers along the height direction of the anti-splash device 10. This facilitates the formation of a multi-layered bubble-breaking structure, increasing the number of collisions between bubbles and the multiple filler particles 12, thereby further reducing splashing. As a specific example, the number of layers of multiple filler particles 12 can be 2 to 5.

[0050] In some embodiments, the filling particles 12 located in the upper layer and the filling particles 12 located in the lower layer are arranged alternately.

[0051] In these embodiments, by staggering the upper and lower layers of filler particles 12, a non-uniform gap pore gradient can be formed to further increase the number of collisions between bubbles and particles, thereby reducing splashing to some extent.

[0052] like Figure 2 As shown, multiple filler particles 12 are stacked in multiple layers along the height direction of the anti-splash device 10, with the filler particles 12 in the upper layer and those in the lower layer arranged alternately. Figure 2 In the example shown, the multiple filler particles 12 are arranged in five layers.

[0053] According to other embodiments of this application, such as Figure 3 As shown, the anti-splash device 10 also includes a partition mesh plate 13, which is spaced apart in the receiving cavity 111 and divides the receiving cavity 111 into multiple sub-cavities in the height direction of the anti-splash device 10. Multiple filling particles 12 are respectively disposed in the corresponding sub-cavities, and the filling particles 12 in each sub-cavity can roll in the corresponding sub-cavity under the pressure of external gas.

[0054] In this embodiment, by providing the separator mesh 13, it is easy to arrange multiple layers of filling particles 12, so as to achieve the purpose of destroying bubbles generated during cooking as much as possible through a multi-level bubble-breaking structure. In addition, the separator mesh 13 effectively separates the filling particles 12 between each layer, which can effectively prevent them from interfering with each other during movement.

[0055] In some embodiments, the height of the sub-cavity is greater than the size of the filling particles 12, which facilitates the rolling of the filling particles 12 in each sub-cavity under the pressure of the external gas, thus preparing for splash prevention.

[0056] In some embodiments, the height of the sub-cavity is 1.1 to 3 times the size of the filling particles 12. This achieves the purpose of allowing the filling particles 12 in each sub-cavity to roll within the corresponding sub-cavity under the pressure of external gas, while minimizing the overall height of the anti-splash device, thus making it easy to apply to the size requirements of the container lid 100 of the cooking container.

[0057] In some embodiments, the filler particles 12 are inorganic non-metallic particles or metallic particles. As specific examples, inorganic non-metallic particles include titanium oxide, iron oxide, aluminum oxide, titanium carbide, or titanium nitride, while metallic particles include titanium particles, stainless steel particles, or aluminum particles. It should be noted that this application does not intentionally limit the material of the filler particles; those skilled in the art can select one or more of these materials from existing materials based on the teachings of this application.

[0058] In these embodiments, the material types of the filling particles 12 are diverse, enabling the manufacture of various types of anti-splash devices to expand the types of cooking containers that can use anti-splash devices and to make preferential settings based on actual needs.

[0059] In some embodiments, the inorganic non-metallic particles are molecular sieve particles, wherein the particle size of the molecular sieve particles is 1.5 mm to 3.0 mm. Molecular sieve particles of this size can provide a suitable specific surface area, which can increase the probability of contact with bubbles, thereby increasing the possibility of breaking bubbles and suppressing splashing of the cooking container during use.

[0060] In some embodiments, the pore size of the molecular sieve particles is The appropriate pore size of molecular sieve particles can ensure gas flow performance, thereby optimizing the gas flow performance of the anti-splash device and improving its anti-splash performance.

[0061] In some embodiments, the molecular sieve particles include one of aluminosilicate molecular sieves, titanium silicate molecular sieves, and phosphorus aluminosilicate molecular sieves, which can diversify the types of molecular sieve particles used as filler particles 12, enabling the manufacture of various types of anti-splash devices, thereby expanding the types of cooking containers that can be used with anti-splash devices and allowing for preferential settings based on actual needs.

[0062] In some embodiments, the molecular sieve particles are microporous molecular sieve particles. As a specific example, the molecular sieve particles have a uniform pore structure with a porosity of 10%-30%, a pore size of 0.3 nm-1 nm, and uniformly spaced pores. Such a pore structure provides more uniform solid and porous portions, which improves the heat transfer uniformity of the anti-splash device, ensuring uniform and stable heating in all areas of the device. This helps prevent excessive localized air bubbles during application, thus avoiding negative impacts on the anti-splash effect.

[0063] In some embodiments, such as Figure 4 As shown, the filler particles 12 have a rough surface at the nanoscale, thus enabling them to mechanically puncture air bubbles using their surface shape to further enhance the anti-splashing effect.

[0064] According to a second aspect of the present invention, a container lid is provided for a cooking container, wherein, as Figure 5 and Figure 6 As shown, the container lid 100 includes a lid body 20 and the aforementioned anti-splash device 10. The lid body 20 is provided with an exhaust port 21, and the anti-splash device 10 is installed on the lid body 20 corresponding to the exhaust port 21.

[0065] Specifically, the anti-splash device includes a housing 11 and a plurality of filler particles 12. The housing 11 has a cavity 111 inside, and the housing 11 is provided with a through hole 112 that connects the cavity 111 to the outside. When external gas passes through the cavity 111, the plurality of filler particles can roll under the pressure of the external gas.

[0066] According to the container lid of this utility model, the mixed gas in the cooking chamber of the cooking container (which is considered external gas relative to the anti-splash device) will push the bubbles through the receiving chamber 111 of the anti-splash device. At this time, each filling particle 12 can roll under the pressure of the external gas to break the bubbles. Meanwhile, the pressure has been released to a certain extent during this process. Under these circumstances, most of the liquid and solid particles carried in the bubbles will flow back into the cooking chamber of the cooking container in time under their own gravity, which can prevent them from continuing to splash out under the push of the next surge of gas. Thus, the anti-splash device of this utility model can not only prevent the liquid and solid particles carried in the bubbles from splashing and causing harm to the human body, but also greatly reduce the trouble of cleaning the stove.

[0067] In some embodiments, the container lid 100 further includes a pressure regulating valve 50, which is disposed at the outlet of the exhaust port 21, and the anti-splash device 10 is installed at the inlet of the exhaust port 21. In this invention, the pressure regulating valve 50 can regulate the internal pressure of the cooking container, specifically by dynamically adjusting the opening of the exhaust port 21 to maintain the internal pressure balance of the cooking container.

[0068] In these embodiments, during the use of the cooking container, since the anti-splash device 10 is installed at the air inlet of the exhaust port 21, the anti-splash device 10 can prevent the exhaust port 21 of the cooking container from being blocked by foreign objects such as solid particles during cooking, thereby preventing poor exhaust and causing safety issues or splashing problems. Since the pressure regulating valve 50 is located at the air outlet of the exhaust port 21, the reliability of the pressure regulating valve 50 in regulating pressure can be ensured, thereby ensuring the normal cooking function of the cooking container and simultaneously improving the safety of use.

[0069] In some embodiments, an exhaust pipe 40 is provided in the exhaust port 21. The exhaust pipe 40 includes an air inlet section near the inner side of the cover body 20 and an exhaust section near the outer side of the cover body 20. The anti-splash device 10 is connected to the air inlet section of the exhaust pipe 40, and the pressure regulating valve 50 is connected to the exhaust section of the exhaust pipe 40.

[0070] In this invention, the pressure regulating valve 50 can regulate the internal pressure of the cooking container. Specifically, the internal pressure balance of the cooking container can be maintained by dynamically adjusting the opening of the exhaust pipe 40.

[0071] In these embodiments, by providing an exhaust pipe 40 in the exhaust port 21 to connect the anti-splash device and the pressure regulating valve, not only is connection and installation easier, but maintainability is also improved.

[0072] According to a third aspect of the present invention, a cooking container is provided, wherein the cooking container includes a container body and a container lid 100 connected to the container body, and the container lid is the container lid 100 described above.
