Description

Technical Field

[0001] The utility model belongs to the technical field of oil pot accessories, and particularly relates to an oil pot cover for maintaining the air pressure balance inside and outside the oil pot. Background Art

[0002] Due to the global household habit of mainly eating at home, but since cooks add oil and salt based on feeling and eating habits, it leads to excessive oil and salt, causing a series of health problems.

[0003] For the convenience of adding oil, oil pots are widely used. However, the structure of the existing oil pots is simple. After the oil in the oil pot is poured out, the air pressure inside the pot changes, which is not conducive to controlling the amount of oil when pouring oil next time. Summary of the Utility Model

[0004] The utility model provides an oil pot cover for maintaining the air pressure balance inside and outside the oil pot, aiming to solve the problem that the air pressure balance inside and outside the oil pot cannot be guaranteed when pouring oil in the existing technology.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows:

[0006] An oil pot cover for maintaining the air pressure balance inside and outside the oil pot, including a cover plate for sealing the oil pot, and a valve body provided on the cover plate for allowing outside air to enter the oil pot during the oil pouring process;

[0007] The cover plate is provided with an air hole for installing the valve body. The air hole is a through hole. The valve body includes a valve post that is in clearance fit with the air hole and a limiting portion provided on the valve post to prevent the valve post from detaching from the air hole;

[0008] The diameter of the limiting portion is larger than the diameter of the air hole, and the valve post is slidably connected inside the air hole.

[0009] A further improved scheme: when the inclination angle of the oil pot is greater than a preset angle, the limiting portion blocks the air hole.

[0010] Based on the above technical solution: when the oil pot is tilted to a certain angle, i.e., the preset angle, the limiting portion will automatically block the air hole. The main purpose of this design is to prevent the oil liquid from leaking out from the air hole during the tilting or pouring process of the oil pot. Oil leakage not only causes waste of oil liquid, but also may pollute the surrounding environment and even pose a safety hazard in some cases. By automatically blocking the air hole when the oil pot is tilted, these potential risks can be effectively avoided, improving the safety of use.

[0011] A further improved scheme: the preset angle is 90 degrees.

[0012] Based on the above technical solution: The user doesn't need to worry about the oil pot suddenly leaking oil when pouring the oil, making the pouring process more stable and smooth. The automatic blocking mechanism reduces the oil leakage problem caused by improper human operation and improves the convenience of use.

[0013] Further improved solution: The oil pot lid that keeps the air pressure inside and outside the oil pot balanced further includes an oil pouring spout, and the air hole is an inclined hole with the upper end facing the direction of the oil pouring spout.

[0014] Based on the above technical solution: The inclined hole design allows the air inside and outside the oil pot to circulate freely, so as to automatically supplement the external air into the oil pot when the oil level decreases, keeping the air pressure inside and outside the oil pot balanced. This helps prevent the oil pot from being flattened due to too low internal air pressure, or expanding or even bursting due to too high air pressure. When the oil pot is tilted or poured, the inclined hole design can further make the valve stem easy to move, so as to block the air hole in time and prevent oil leakage.

[0015] Further improved solution: The limiting part includes an upper limiting block and a lower limiting block, and the cover plate is located between the upper limiting block and the lower limiting block.

[0016] Based on the above technical solution: The upper limiting block and the lower limiting block jointly provide a stable limiting function for the cover plate, preventing the valve stem from accidentally falling off or being misaligned during the tilting or moving process of the oil pot, thus avoiding the risk of oil leakage caused by the accidental opening of the air hole.

[0017] Further improved solution: The shape of the upper limiting block is a frustum of a cone with a smaller upper part and a larger lower part, the diameter of the lower end of the upper limiting block is larger than the diameter of the air hole, and the shape of the lower limiting block is a frustum of a cone with a smaller upper part and a larger lower part.

[0018] Based on the above technical solution: The upper limiting block is designed as a frustum of a cone, and the diameter of its lower end is larger than the diameter of the air hole. This design ensures that when the valve stem is in a vertical state, the upper limiting block can block the air hole to prevent dust from entering the air hole.

[0019] Further improved solution: The diameter of the upper end of the lower limiting block is equal to the diameter of the valve stem.

[0020] Based on the above technical solution: The diameter of the upper end of the lower limiting block is equal to the diameter of the valve stem, ensuring an accurate fit between the two. This design enables the valve stem and the air hole to be correctly matched, while reducing the risk of wobbling or leakage caused by too large a gap.

[0021] Further improved solution: The upper limiting block and the lower limiting block are both coaxially arranged with the valve stem.

[0022] Based on the above technical solution: Coaxial setting means that the upper limit block, the lower limit block, and the valve stem share the same axis. Coaxial setting helps to reduce the friction and resistance between the valve stem and the limit block during the up and down movement, making the movement of the valve stem smoother.

[0023] Further improved solution: The volume of the upper limit block is smaller than the volume of the lower limit block.

[0024] Based on the above technical solution: The upper limit block has a smaller volume and lighter weight, while the lower limit block has a larger volume and heavier weight. When the oil pot is tilted, the lower limit block can use its own gravity to timely push the valve stem to move, so that the lower limit block can timely block the air hole to prevent oil leakage.

[0025] Further improved solution: The valve body is a silicone valve.

[0026] Based on the above technical solution: The silicone valve body has good elasticity and resilience, and can closely fit at the air hole or the opening of the oil passage to form an effective seal. This sealing performance helps to prevent oil leakage and maintain the cleanliness inside the oil pot and the purity of the oil. Silicone is a non-toxic, odorless, and environmentally friendly material that meets food safety standards. Therefore, the oil pot with a silicone valve body can ensure the safety and hygiene of the oil, and will not cause harm to the health of users.

[0027] The beneficial effects of the present utility model are as follows:

[0028] During the process of pouring oil in the present utility model, as the oil flows out, the air pressure inside the oil pot will gradually decrease. The valve body design in the present utility model allows external air to enter the oil pot through the air hole, thereby maintaining the air pressure balance inside and outside the oil pot. This balanced state effectively prevents problems such as unsmooth pouring of oil caused by air pressure difference or deformation of the oil pot. The valve body is composed of a valve stem and a limiting part. The diameter of the limiting part is larger than the diameter of the air hole, ensuring the stability of the valve stem in the air hole and preventing oil from leaking through the air hole during the oil pouring process. This design not only ensures the sealing performance of the oil pot but also realizes the balanced adjustment of air pressure. Users can easily achieve the sealing and opening of the oil pot, improving the convenience of use. By solving the air pressure balance problem during oil pouring, the present utility model significantly improves the user experience. Users no longer need to worry about problems such as unsmooth pouring of oil or deformation of the oil pot during use, making the oil pouring process smoother and more efficient.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the attached drawings in the embodiments of the present utility model. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0036] Refer to Figures 1 to 3 , an oil kettle lid for maintaining the air pressure balance inside and outside the oil kettle, including a cover plate 1 for sealing the oil kettle, and a valve body 2 provided on the cover plate 1 for allowing external air to enter the oil kettle during the pouring process;

[0037] An air hole 3 for installing the valve body 2 is provided on the cover plate 1. The air hole 3 is a through hole. The valve body 2 includes a valve post 4 that is in clearance fit with the air hole 3 and a limiting portion provided on the valve post 4 to prevent the valve post 4 from detaching from the air hole 3;

[0038] The diameter of the limiting portion is greater than the diameter of the air hole 3, and the valve post 4 is slidably connected to the air hole 3.

[0039] Wherein: when the inclination angle of the oil kettle is greater than a preset angle, the limiting portion blocks the air hole 3.

[0040] The preset angle is 90 degrees.

[0041] When the tilting angle of the oil pot is not greater than 90 degrees, at this time, the tilting angle of the oil pot is relatively small, and the oil in the oil pot will not leak from the air hole 3 during the oil pouring process. It only needs to make the air hole 3 have the function of balancing air pressure. When the tilting angle of the oil pot is greater than 90 degrees, due to the excessive tilting angle of the oil pot, the oil in the oil pot may leak from the air hole 3. Therefore, when the tilting angle of the oil pot is greater than 90 degrees, under the action of the gravity of the limiting part, the valve column 4 is pushed to move, so that the lower limiting block 7 blocks the air hole 3 to prevent oil leakage.

[0042] Wherein: the oil pot cover for maintaining the air pressure balance inside and outside the oil pot further includes an oil pouring nozzle 5, and the air hole 3 is an inclined hole with the upper end facing the direction of the oil pouring nozzle 5. The inclined hole makes the upper end of the valve column 4 tilt towards the oil pouring nozzle 5 during the oil pouring process of the oil pot, and the valve column 4 can slide in time, so that the lower limiting block 7 blocks the air hole 3 to prevent oil leakage.

[0043] Wherein: the limiting part includes an upper limiting block 6 and a lower limiting block 7, and the cover plate 1 is located between the upper limiting block 6 and the lower limiting block 7. The shape of the upper limiting block 6 is a frustum of a cone with a smaller upper part and a larger lower part, the diameter of the lower end of the upper limiting block is larger than the diameter of the air hole 3, and the shape of the lower limiting block 7 is a frustum of a cone with a smaller upper part and a larger lower part.

[0044] Reference Figures 1 to 3 Specifically: the diameter of the upper end of the lower limiting block 7 is equal to the diameter of the valve column 4. The upper limiting block 6 and the lower limiting block 7 are both coaxially arranged with the valve column 4.

[0045] Specifically: the volume of the upper limiting block 6 is smaller than the volume of the lower limiting block 7. The valve body 2 is a silicone valve.

[0046] The upper limiting block 6 and the valve column 4, as well as the lower limiting block 7 and the valve column 4, can both be of an integral structure.

[0047] The upper limiting block 6 or the lower limiting block 7 may not be of an integral structure with the valve column 4 either. For example, both the upper limiting block 6 and the lower limiting block 7 can be connected to the valve column 4 by threads.

[0048] The working principle of this embodiment:

[0049] In the normal non-tilted state, since the diameter of the limiting part is larger than the diameter of the air hole 3, the valve column 4 is in a vertical state, and the upper limiting block 6 contacts the cover plate 1 to prevent external air from entering the inside of the oil pot and maintain the airtightness of the oil pot.

[0050] When the oil pot starts to tilt to pour out the oil, as the oil flows out, the internal space of the oil pot gradually increases, resulting in a decrease in the internal air pressure. As the oil continues to be poured out, the valve post 4 will tilt according to the tilting state of the oil pot. The valve post 4 contacts one side of the air hole 3, and a gap is generated between the other side of the valve rod 4 and the side wall of the air hole. In addition, the limiting part is separated from the cover plate 1 to generate a gap, and the air hole 3 is opened, allowing air to enter the oil pot to keep the air pressure in the oil pot balanced.

[0051] When the tilting angle of the oil pot is greater than 90 degrees, the sliding of the valve post 4 causes the lower limit block 7 to block the air hole 3 to prevent oil leakage from the air hole 3.

[0052] When the oil pot stops tilting and is placed steadily again, under the action of its own gravity, the valve post 4 slides downward, and the upper limit block 6 blocks the air hole 3 to prevent dust from entering the air hole 3.

[0053] The utility model is not limited to the above optional embodiments. On the premise of not conflicting with each other, various solutions can be arbitrarily combined; anyone can obtain other various forms of products under the inspiration of the utility model. However, no matter what changes are made in its shape or structure, as long as the technical solutions fall within the scope defined by the claims of the utility model, they are all within the protection scope of the utility model.
