[0033] See also Figure 1-7 As shown, a container cover with a magnetic structure date display function of the present invention comprises a container cover shell 1, a transparent top cover 11 installed on the upper part of the container cover shell 1, and a vacuum device installed in the container cover shell 1; the container cover is installed on the top of the container tank body, and the specific installation principle is the same as the prior art. The innovation of the technical solution is not in the installation structure, but in the innovation of the magnetic structure date display function. The specific solution is as follows;

[0034] At least two grooves 13 are provided on the upper part of the container cover shell 1, and sunken slots 14 are evenly opened in the grooves 13, and a magnetic bead is placed in each groove 13; a magnetic ring 16 corresponding to the groove 13 is installed at the bottom of the container cover shell 1 through the installation groove; the magnetic bead has a magnetic attraction ability, which can be a magnet bead or a steel bead, and the magnetic ring 16 is a ring with magnetic attraction ability, which can be an iron ring corresponding to the magnet bead or a magnet ring corresponding to the steel bead;

[0035] The transparent top cover 11 is provided with numbers corresponding to the sunken slots 14 for displaying the month and date; in this specific embodiment, the slots 13 are arranged in an arc structure, such as Figure 4The structure shown in the figure is arranged on both sides or arranged side by side; in this specific embodiment, two grooves are specifically used, one long and one short; the groove 13 on the container cover shell 1 has at least one internal sunken slot 14 with twelve, and at least one internal sunken slot 14 with thirty-one; in this specific embodiment, specifically, thirty-one sunken slots 14 are arranged in the long groove 13, which are used to correspond to the numbers 1-31 on the transparent top cover 11, representing 31 days of a month; twelve sunken slots 14 are arranged in the short groove 13, which are used to correspond to the numbers 1-12 on the transparent top cover 11, representing 12 months of a year; the corresponding positions of the magnetic beads installed in at least two grooves 13 are used to represent the corresponding specific dates;

[0036] In this specific embodiment, the sunken slot 14 is as follows Figure 7 As shown, the use of a sunken arc-shaped slot can limit the magnetic beads. After adjusting the time, when the magnetic beads are in the arc-shaped slot and are closest to the magnetic ring, the suction force with the magnetic ring 16 is the largest, thereby achieving the purpose of fixing without misalignment.

[0037] As another example, Figure 8 As shown, in this specific embodiment, a sunken wave-shaped groove is used to limit the magnetic beads through the side walls of the wave-shaped groove. After adjusting the time, when the magnetic beads are in the arc-shaped groove hole and are closest to the magnetic ring, the suction force with the magnetic ring 16 is the largest, thereby achieving the purpose of fixing without misalignment;

[0038] At least one iron sheet 17 is attached to the inner wall of the container cover shell 1, and a pick-up spoon 3 is magnetically attached to the outer wall of the container cover shell 1.

Figure 5 As shown, it can be on the inner upper part or inner side of the container cover shell 1; the corresponding strong magnetic block 31 on the picking spoon 3 is arranged at the end of the handle or the side of the handle, and the suction force of the strong magnetic block 31 is greater than the suction force of the magnetic ring 16. When the strong magnetic block 31 is attached to the transparent top cover 11, the magnetic beads can be sucked up, and then moved to the corresponding position where they need to be placed and then put down, thereby realizing the movement of the position; the suction force of the magnetic ring 16 can make the magnetic beads be sucked in the sunken slot 14, and they will not slide out of the sunken slot 14 when the container cover shell 1 is tilted, that is, the suction force provided by the magnetic ring 16 is greater than the gravity of the magnetic beads themselves, and the suction force of the strong magnetic block 31 is greater than the suction force of the magnetic ring 16.

[0039] The container cover shell 1 and the transparent top cover 11 are made of non-magnetic materials, and in this specific embodiment, plastic materials are used, which will not be magnetically attracted by the magnetic ring 16 and the strong magnetic block 31.

[0040] The distance between the surface of the channel 13 and the bottom of the transparent top cover 11 is greater than the diameter of the magnetic beads, so that the magnetic beads can change positions between different sunken slots 14 in the same channel 13 .

[0041] A through hole is provided at the center of the upper portion of the container cover shell 1 , and a vacuum button 21 extends out of the through hole. The vacuum button 21 is mounted on the control board 2 . A gap is formed between the top of the vacuum button 21 and the bottom of the transparent top cover 11 .

[0042] The vacuum pump is installed below the control board 2; a screw locking column 15 is installed on the upper part of the container cover shell 1, and the screw passes through the screw locking column 15 to lock and connect the control board 2;

[0043] The vacuum device includes a vacuum pump, a solenoid valve, a battery and a gas pipeline, etc., which are located at the bottom of the control board 2. The vacuum pump, the solenoid valve and the battery all adopt a miniature structure, which is consistent with the component models and functions used in the background technology, and the specific models can be purchased conventionally on the market; the specific connection relationship is: USB interface, LED light group, battery, pressure sensor, vacuum pump, solenoid valve, gas one-way valve, vacuum switch button are electrically connected to the single-chip computer respectively; the specific principle is not the protection point of this technical solution and will not be repeated.

[0044] The transparent top cover 11 is installed on the upper part of the container cover shell 1 through the installation groove 12, and the connection position is airtightly sealed by using sealant.

[0045] The present invention provides at least two grooves on the upper part of the container cover shell, and evenly provides sunken slots in the grooves, a magnetic bead is placed in each groove, a magnetic ring corresponding to the groove is installed at the bottom of the container cover shell, and numbers corresponding to the sunken slots for displaying the month and date are provided on the transparent top cover; a picking spoon is magnetically attracted on the outer wall of the container cover shell, and a strong magnetic block on the picking spoon is attached to the surface of the transparent top cover, so that the magnetic beads in the sunken slots can be magnetically attracted and moved to the bottom of the changed sunken slots, and the magnetic beads can be put down after the picking spoon is removed, thereby realizing the movement of the positions of the magnetic beads in different grooves, and since the transparent top cover is provided with numbers displaying the month and date, the function of recording the month and date is achieved; the scheme is easy to operate, simple in structure, does not rely on electronic equipment, can be repeatedly operated and used, and has low use cost.
