One of the support 20 and the deformation part 12 is provided with a first connection hole 41, and the other is provided with a connection post 30, the connection post 30 being located in the first connection hole 41 to enable connection of the support 20 with the sensor body 10.

For example, in some embodiments, as shown in fig. 3-5, the support portion 20 is provided with a connection post 30, the deformation portion 12 is provided with a first connection hole 41, the connection post 30 is interference-fitted in the first connection hole 41 to connect the support portion 20 and the deformation portion 12, and the deformation portion 12 is deformed relative to the body 11 by the weight acting on the support portion 20. When the support 20 is supported on the placing surface, the weight of the object to be weighed (e.g., the cooking utensil 200) acts on the support 20, and the deformation portion 12 connected to the support 20 can be deformed with respect to the body 11. Further, when the food is placed in the cooking utensil 200, the deformation amount in the deformation portion 12 is larger relative to the deformation amount when the cooking utensil 200 is empty, and the larger the weight of the food in the cooking utensil 200 is, the larger the deformation amount of the deformation portion 12 is, that is, the deformation amount of the deformation portion 12 is positively correlated with the weight of the food in the cooking utensil 200.

For example, when cooking rice, the user can judge whether to continue to add rice or add water according to the detected rice amount and water amount without observing the water level line on the inner wall of the inner pot, so that the operation is more convenient and less worry.

According to some embodiments of the present invention, as shown in fig. 3 and 5, the support portion 20 is further provided with at least one reinforcement portion 21, the reinforcement portion 21 being clearance-fitted to the side surface of the deformation portion 12. When the supporting portion 20 is impacted, the reinforcing portion 21 can be matched with the side face of the deformation portion 12 to offset the impact force, the impact force is prevented from being totally acted on the connecting column 30 in the first connecting hole 41 to cause the fracture of the connecting column 30, the impact resistance of the weight sensor 100 is increased when the impact force is impacted, the service life of the weight sensor 100 is longer, and the weighing performance of the cooking appliance 200 is good.

In some embodiments, the reinforcing part 21 does not exceed the end surface of the sensor body 10 far away from the supporting part 20, that is, the upper surface of the reinforcing part 21 does not exceed the upper surface of the sensor body 10 as shown in fig. 5, which can avoid weighing inaccuracy caused by deformation of the deformation part 12 due to too long reinforcing part 21, ensure weighing accuracy of the weight sensor 100, and reduce weighing error.

In some embodiments, as shown in fig. 3 and 5, the deformation portion 12 includes a plurality of arm portions 121 and a connecting arm 122.

And one end of at least one arm part 121 far away from the connecting arm 122 is connected with the body 11 to realize the connection between the body 11 and the deformation part 12, and the deformation part 12 is easier to elastically deform relative to the body 11, the structure of the sensor main body 10 is simple, and the weighing sensitivity is high.

Meanwhile, the reinforcing part 21 is located between two adjacent arm parts 121, so that weighing failure caused by contact of the reinforcing part 21 with the body 11 is avoided.

In some embodiments, as shown in fig. 5, at least one arm 121 is provided with a first connection hole 41, the connection column 30 is located in the first connection hole 41, the reinforcement part 21 is in clearance fit with the side surface of the arm 121 provided with the first connection hole 41, so that the hole wall of the first connection hole 41 is clamped between the reinforcement part 21 and the connection column 30, thereby increasing the reliability of the connection between the support part 20 and the sensor body 10, ensuring stable connection, and making the weighing performance of the cooking utensil 200 good.

For example, in the embodiment shown in fig. 5, the sensor main body 10 includes a main body 11 and a deformation portion 12, the deformation portion 12 includes a plurality of arm portions 121 disposed at intervals, wherein two outermost arm portions 121 are respectively provided with first connection holes 41, two connection holes 30 are respectively located in the two first connection holes 41, two reinforcing portions 21 are disposed on the inner sides of the connection holes 30, and the two reinforcing portions 21 are respectively in clearance fit with the inner side surfaces of the outermost arm portions 121. The two connected arm parts 121 can be deformed relative to the body 11 by the stress of the supporting part 20, so that the stress distribution of the deformation part 12 is more uniform, the correlation between the deformation amount of the deformation part 12 and the weight of the food material is more accurate, the weight detection precision is improved, and the deformation part 12 can be prevented from being deformed irreversibly due to uneven stress. Meanwhile, the reinforcing part 21 effectively improves the impact resistance of the supporting part 20 without affecting the measurement accuracy, thereby avoiding the risk of stress fracture of the connecting column 30 and prolonging the service life of the weight sensor 100.

According to some embodiments of the utility model, the side face cooperation of rib 21 and deformation portion 12 to increase lifting surface, improve shock resistance and structural strength.

For example, in some embodiments, as shown in fig. 3 and 5, the reinforcing portion 21 is a strip-shaped rib, and the side surface of the deformation portion 12 that is matched with the strip-shaped rib is a plane, so that when a collision occurs, the strip-shaped rib is attached to the side surface of the deformation portion 12, so as to increase the stress area, improve the impact resistance, avoid the reinforcing portion 21 from being broken due to stress concentration, and further reduce the risk of the connection column 30 from being broken due to stress.

For another example, in some embodiments, the reinforcing portion 21 is an arc-shaped rib, and the side surface of the deformation portion 12 that is matched with the arc-shaped rib is an arc surface, so that when a collision occurs, the arc-shaped rib can contact with the arc surface of the deformation portion 12, thereby increasing the stress area, improving the impact resistance, avoiding the reinforcing portion 21 from being fractured due to stress concentration, and further reducing the risk of stress fracture of the connecting column 30.

In the part production process, because size error leads to the size not conform, make the supporting part have the risk of pressing the body in the process of weighing, cause to weigh inefficacy or weigh inaccurately.

Thus, in some embodiments of the present invention, as shown in fig. 3-6, the body 11 is generally square annular disposed around the deformation 12, where the sides of the generally square annular include, but are not limited to, straight sides. For example, in the example shown in fig. 3, the body 11 includes four straight sides, and the four straight sides are sequentially connected end to end by four arc-shaped sides to form a ring-shaped structure. At least a part of the outer peripheral surface of the support portion 20 near the deformation portion 12 is formed as a slope 23, in other words, at least an upper part of the outer peripheral surface of the support portion 20 is formed as a slope 23. The inclined surface 23 extends obliquely inward in a direction close to the deformation portion 12, in other words, the inclined surface 23 extends obliquely upward in a direction close to the center of the body 11, in other words, the area surrounded by the inclined surface 23 decreases gradually in a direction close to the deformation portion 12. Therefore, the distance between the outer peripheral surface of the support part 20 and the body 11 is increased upwards, so that the fault tolerance of the support part 20 and the sensor main body 10 is increased, the support part 20 and the sensor main body 10 are ensured not to interfere in the weighing process, the assembly meets the use requirement, and the production cost is reduced.

As shown in fig. 3, 5 and 6, the outer peripheral surface of the support portion 20 may be partially formed as an inclined surface 23, or the outer peripheral surface of the support portion 20 may be entirely formed as the inclined surface 23. In the above structure, it is possible to prevent the supporting portion 20 from being pressed against the body 11 of the sensor main body 10 due to an error generated in manufacturing parts during the manufacturing process. The fault tolerance of the supporting part 20 and the sensor body 10 is increased, and the production cost is reduced.

According to some embodiments of the present invention, as shown in fig. 3, 5 and 6, the inclined plane 23 is a plane or a cambered surface, which can avoid the error generated by the manufacturing of parts in the production process, and the situation that the supporting portion 20 presses the body 11 of the sensor main body 10 can be avoided. And the plane or the cambered surface is convenient to process, so that the production efficiency is improved.

In some embodiments, as shown in fig. 3, 5 and 6, a chamfer is provided at a connection between the outer circumferential surface of the supporting portion 20 and the end surface of the supporting portion 20 facing the deformation portion 12 (i.e., the end surface provided with the connecting post 30) to form an inclined surface 23, and the chamfer is a chamfer angle (corresponding to the inclined surface 23 being a plane) or a fillet angle (corresponding to the inclined surface 23 being an arc surface), so that the processing is more convenient and the production efficiency is improved.
