The guide ribs located on the upper side are arranged in a V shape, and the guide ribs located on the lower side are arranged in an inverted V shape. A channel 191 is formed between the two guide ribs, and the width of the two sides of the channel 191 is greater than the width in the middle.

[0096] During installation, if Figure 3 and Figure 7 As shown, the seasoning bin 100 is pushed into the base 300 from right to left, and the first guide stopper 316 first enters the left side of the channel 191. The bidirectional gradual guide rib 190 is deformed by the extrusion of the first guide stopper 316. The first guide stopper 316 passes through the middle narrow position of the channel 191 and then enters the right side of the channel 191. At this time, due to the restriction of the middle narrow position of the channel 191 and the first guide stopper 316, the seasoning bin 100 will not automatically separate from the base 300.

[0097] When removing, force is applied to pull the seasoning bin 100 out from left to right. At this time, the first guide stopper 316 is squeezed to deform the bidirectional gradual guide rib 190. The first guide stopper 316 passes through the middle narrow position of the channel 191 and enters the left side of the channel 191. The seasoning bin 100 is pulled out smoothly.

[0098] Since the first guide stopper 316 is in the shape of a horizontally placed teardrop, and its outer contour curve is set, and the shape of the bidirectional gradual guide rib 190 is added, the first guide stopper 316 can guide the movement of the seasoning bin 100 during the installation and removal process of the seasoning bin 100.

[0099] Then Figure 7 As shown, the second guide stopper 317 is configured as a straight-line convex rib, and the beginning of the convex rib (i.e. Figure 7 The thickness of the second guide limit blocks 317 gradually decreases, and the seasoning bin 100 can be guided to be inserted between the two second guide limit blocks 317. The two second guide limit blocks 317 clamp the seasoning bin 100, so that the seasoning bin 100 is stably installed on the base 300.

[0100] Furthermore, when the power shaft 331 of the power element 330 drives the spiral propulsion rod 200 to rotate, the seasoning bin 100 will not be pushed out of the base 300 due to the cooperation between the first guide limit block 316 and the bidirectional gradual guide rib 190 .

[0101] The dry seasoning box assembly of the utility model is suitable for use in cooking equipment, can achieve the purpose of accurate feeding, and is also equipped with a weighing sensor 320, which can notify the user of a shortage of seasoning in the seasoning bin 100 and notify the user to replenish seasoning, making it more convenient to use.
