[0002] In the field of storage tool technology, sealed boxes are a common storage container widely used to store various items. Traditional sealed box design mainly focuses on providing good sealing performance to prevent external air, moisture, dust and other pollutants from entering the box, thereby protecting the quality of the stored items and extending their shelf life. However, for some special types of items, such as coffee beans and other items with post-ripening characteristics or life characteristics, gases such as CO will be generated during storage. The accumulation of these gases may not only affect the freshness and original flavor of the items, but may even cause the quality of the items to deteriorate or deteriorate.

[0003] Although the existing sealed box design can provide excellent sealing effect, it often ignores the need for gas discharge in the box. Due to the tightness of the sealed box, the generated gas cannot be discharged in time and accumulates in the box for a long time, which has an adverse effect on the quality of the stored items. Therefore, how to achieve effective discharge of the gas in the box while maintaining the good sealing performance of the sealed box has become an urgent problem to be solved in the current storage tool technology field.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides a sealing box with a rotating structure, such as Figure 1-Figure 3 As shown, it includes a box body 1, a sealing cover 2 is installed on the top of the box body 1, a knob 3 is installed on the top of the sealing cover 2, a rotating plate 4 is installed on the upper part of the interior of the box body 1, a one-way air outlet cover plate 5 is installed on the lower part of the rotating plate 4, a plurality of air outlets 21 are arranged on the top surface of the sealing cover 2, the bottom of the knob 3 is connected to the rotating plate 4 through a rotating shaft, an air inlet pipe 41 is installed on the bottom of the rotating plate 4, an air outlet hole 42 is arranged on the top of the rotating plate 4, the interior of the rotating plate 4 is a hollow structure, a top ball 51 is installed on the one-way air outlet cover plate 5, the rotating plate 4 can rotate to drive the bottom end of the air inlet pipe 41 to be stuck on the top ball 51, so as to achieve effective sealing.

[0022] In this embodiment, a guide sleeve 52 is installed on the top of the one-way air outlet cover plate 5 near the top ball 51, and a guide rod 53 is arranged inside the guide sleeve 52. The top end of the guide rod 53 is connected to the top ball 51, and the outer sleeve of the guide rod 53 is provided with a spring 54, which facilitates to tighten the top ball 51 to the bottom end of the intake pipe 41 to ensure effective sealing.

[0023] Specifically, the bottom end of the spring 54 is abutted against the top of the guide sleeve 52 , and the top end of the spring 54 is welded and fixed to the bottom of the top ball 51 , so as to facilitate the installation and positioning of the spring 54 .

[0024] Furthermore, an air outlet cavity 55 is provided in the middle of the one-way air outlet cover plate 5, a sealing ball 553 is provided inside the air outlet cavity 55, an upper opening 551 is provided at the top of the air outlet cavity 55, and a lower opening 552 is provided at the bottom of the air outlet cavity 55. When the internal pressure increases, the gas will lift up the sealing ball 553, thereby facilitating the one-way passage of the gas from the bottom to the top.

[0025] Furthermore, the diameter of the sealing ball 553 is greater than the width of the upper opening 551 and the lower opening 552 , and the vertical and lateral dimensions of the air outlet cavity 55 are both greater than the diameter of the sealing ball 553 , thereby ensuring the movement of the sealing ball 553 in the air outlet cavity 55 .

[0026] Furthermore, the size of the bottom opening of the air inlet pipe 41 matches the size of the top ball 51 , and a gasket 411 is installed at the bottom opening of the air inlet pipe 41 to improve the sealing effect.

[0027] Furthermore, the outer wall of the one-way air outlet cover plate 5 is welded and fixed to the inner wall of the box body 1, and a sealing ring is provided between the outer wall of the rotating plate 4 and the inner wall of the box body 1 to improve the sealing effect.

[0028] Furthermore, the bottom of the knob 3 is rotatably connected to the top of the rotating plate 4 via a bearing, so that the rotation of the knob 3 drives the rotating plate 4 to rotate.

[0029] When the sealing box with a rotating structure of the utility model is used, first in the initial state, the knob 3 is in the closed position. At this time, the rotating plate 4 (through the air inlet pipe 41 installed at the bottom thereof) is tightly pressed on the top ball 51 of the one-way air outlet cover plate 5. Due to the action of the spring 54, the top ball 51 is tightly blocked by the opening of the air inlet pipe 41, thereby ensuring the sealing of the box body 1. At this time, the gas in the box body 1 cannot be discharged through the air inlet pipe 41.

[0030] When the gas pressure in the box body 1 increases and the gas needs to be discharged, the user can rotate the knob 3. The rotation of the knob 3 drives the rotating plate 4 to rotate, which makes the bottom end of the air inlet pipe 41 gradually leave the top ball 51, thereby releasing the blockage of the top ball 51. At the same time, as the gas pressure in the box body 1 increases, the sealing ball 553 in the one-way air outlet cover plate 5 will be lifted by the gas pressure, so that the gas can enter the air outlet cavity 55 through the lower opening 552, and then be discharged to the outside of the box through the upper opening 551, the air outlet hole 42 on the rotating plate 4 and the air outlet 21 on the sealing cover 2.

[0031] When the gas pressure in the box body 1 drops to a certain level, the sealing ball 553 will fall back to the bottom of the gas outlet cavity 55 due to its own gravity and the action of the spring 54, blocking the lower opening 552, thereby preventing the gas from continuing to be discharged. At the same time, the user can reversely rotate the knob 3 to reset the rotating plate 4, and the bottom end of the air inlet pipe 41 will be pressed against the top ball 51 again, thereby achieving the re-sealing of the box body 1.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
