The weighing sensor, speaker component, input component, display component and electric guide rail are respectively connected to the controller signal, which can automatically clean the scale pan and keep the scale pan surface clean. However, if the kitchen scale is placed on a tilted table, it will lead to inaccurate weighing. Environmental factors such as vibration and impact will also affect the accuracy of the electronic scale. Therefore, it is necessary to keep the kitchen scale level and stably placed for weighing to improve the weighing accuracy. In addition, when the existing kitchen scale is in use, if the food placement position deviates, it may cause the tray to tilt and fall, thereby reducing the weighing efficiency and weighing accuracy.

[0004] Therefore, a portable foldable intelligent kitchen food precision weighing device is proposed to solve the above problems. Summary of the Invention

[0055] A protective component 6 is provided on the top of the top plate 2, and the protective component 6 includes a U-shaped plate 61 fixedly connected to the top of the top plate 2, an upper cover plate 62 is symmetrically hinged on the top of the U-shaped plate 61, and a front cover plate 63 is symmetrically hinged on the front side of the U-shaped plate 61, and the upper cover plates 62 and the front cover plates 63 are fixed by magnetic strips.

[0056] Two side panels 64 are symmetrically fixedly connected to the inner wall of the U-shaped plate 61 . A mounting groove 65 is defined on one side of the side panel 64 close to the tray portion 4 .

[0057] A side roller 66 is rotatably installed inside the mounting groove 65 . The side rollers 66 are evenly arranged from top to bottom, and adjacent side rollers 66 fit together. The side of the side roller 66 away from the mounting groove 65 fits against the outer wall of the tray portion 4 .

[0058] Example 1: Figure 4-11 As shown, the operator places the pad 1 on the ground at the use location, and the top plate 2 is kept in a horizontal state by the influence of the counterweights 8 on both sides and the judgment of the bubble level 7. When the top plate 2 is leveled, it will drive the rotating ball 53 to rotate, and the rotating ball 53 rotates inside the ball shell 52. The operator rotates the locking disk 55, and the locking disk 55 rotates and descends on the outside of the threaded rod 51. The locking disk 55 drives the side rod 56 to rotate, and the side rod 56 drives the fixing ring 57 and the annular member 54 to rotate, and the annular member 54 rotates on the outside of the ball shell 52.

[0059] The locking plate 55 will also pull the side rod 56 down, and the side rod 56 slides inside the annular member 54. The side rod 56 pulls the fixed ring 57, causing the fixed ring 57 and the pressure ring 58 to rotate and descend. The descent of the pressure ring 58 will squeeze multiple inclined blocks 513, and the inclined blocks 513 will drive the sliding rod 510 and the tightening block 511 to move. The tightening block 511 slides inside the sliding groove 59 and stretches the spring 1 512, so that the multiple tightening blocks 511 will tighten the rotating ball 53 to limit it, thereby limiting the rotating ball 53 and maintaining the initial positioning of the top plate 2.

[0060] Then the operator keeps the top plate 2 stationary with one hand and adjusts the angle of the sleeve 516 with the other hand. The sleeve 516 drives the rotating shaft 515 to rotate and pulls or compresses the adjusting rod 517 to keep the adjusting rod 517 vertically in contact with the bottom surface of the top plate 2. The tightening bolt on the outside of the sleeve 516 is screwed to fix the length of the adjusting rod 517. Then the remaining sleeves 516 and adjusting rods 517 are adjusted accordingly. The descending of the locking plate 55 will also squeeze the contact plates 524 on both sides of the bottom. The contact plates 524 drive the vertical rod 523 to slide into the vertical slot 521, and the vertical rod 523 squeezes the spring 2 522.

[0061] The contact plate 524 drives the pressure rod 525 to squeeze the inclined surface of the trapezoidal bar 526. The trapezoidal bar 526 is squeezed and drives the sliding plate 519 to move. The sliding plate 519 slides on the outside of the fixed rod 518, and the sliding plate 519 drives the tightening sleeve 520 to move, so that the tightening sleeve 520 is stuck on the outside of the rotating shaft 515, thereby locking and limiting the rotating shaft 515, facilitating the limiting and fixing of multiple sleeves 516, thereby further improving the horizontal positioning of the top plate 2, facilitating the subsequent weighing of the scale body 3, and the multiple friction pads 10 at the bottom of the pad 1 improve the placement stability and weighing accuracy, and solve the problem that it is inconvenient to keep the kitchen scale placed horizontally, and the kitchen scale is easily affected by environmental factors such as vibration and impact, which reduces the weighing accuracy.

[0062] Example 2: Figure 12-14 As shown, when not weighing, the two upper covers 62 and the two front covers 63 are closed, and the adjacent upper covers 62 and the adjacent front covers 63 are closed by magnetic strips, thereby facilitating the closure of the top and front surfaces of the U-shaped plate 61 to protect the internal scale body 3.

[0063] When placing food for weighing, if the food is misaligned and causes the tray part 4 to tilt and drop, the tray part 4 will be blocked by the side rollers 66 on both sides, so that it is stuck between adjacent side rollers 66. When the food is in the middle position of the tray part 4, the tray part 4 can drop vertically and stably. At this time, the side rollers 66 guide the tray part 4 to reduce the tilting, thereby maintaining the accurate weighing of the tray part 4. The shoulder strap 9 is convenient for the operator to carry it on his back.

[0064] Working principle: When using this device, first, Figures 1-14 As shown, when not weighing, the two upper covers 62 and the two front covers 63 are closed. When placing food for weighing, if the food is misaligned and causes the tray part 4 to tilt and drop, the tray part 4 will be blocked by the side rollers 66 on both sides, so that it is stuck between the adjacent side rollers 66. When the food is in the middle position of the tray part 4, the tray part 4 can drop vertically and stably, and the shoulder strap 9 is convenient for the operator to carry it on his back. The operator puts the pad 1 on the ground at the use position to keep the top plate 2 in a horizontal state. The operator rotates the locking disk 55, and the multiple pressing blocks 511 press the rotating ball 53 to limit the position, thereby limiting the rotating ball 53 and keeping the top plate 2 After the initial positioning, the operator keeps the top plate 2 stationary with one hand and adjusts the angle of the sleeve 516 with the other hand, keeping the adjusting rod 517 vertically in contact with the bottom surface of the top plate 2, and screwing the tightening bolt on the outside of the sleeve 516 to fix the length of the adjusting rod 517. The lowering of the locking plate 55 will also squeeze the contact plates 524 on both sides of the bottom, and the contact plates 524 will drive the pressure rod 525 to squeeze the inclined surface of the trapezoidal bar 526. The trapezoidal bar 526 will be squeezed and the sliding plate 519 will be moved. The tightening sleeve 520 is stuck on the outside of the rotating shaft 515, thereby locking and limiting the rotating shaft 515, which is convenient for limiting and fixing multiple sleeves 516.
