[0037] The invention provides a vibration-damping foot and intelligent cooking equipment having the vibration-damping foot.

[0038] In this embodiment, refer to Figure 1 The intelligent cooking device includes a base 100 and a mixing container 200 disposed on the base 100. A vibration-damping foot 300 is disposed at the bottom of the base 100. For example, but not limited to, four vibration-damping feet 300 are provided, which are respectively disposed near the four corners of the bottom surface of the base 100. Of course, in other embodiments, the vibration-damping feet 300 can also be specifically set to other numbers and arranged in other forms. Without loss of generality, the intelligent cooking machine can be a mixer with only a mixing function or a food processor with mixing, heating and other functions. In addition, it should be noted that the present design is not limited thereto, and the vibration-damping foot 300 can also be applied to other household electrical appliances that require a vibration-damping function.

[0039] In the embodiment of the present invention, refer to Figures 2 to 4 , the vibration-damping foot 300 comprises:

[0040] The weighing scale rod 1 has a pressure-bearing end 11 and a pressure-resisting end 12 arranged horizontally opposite to each other, and the pressure-bearing end 11 is used to bear the weight of the intelligent cooking device;

[0041] The support leg 2 has a fixed end 21 and a mounting end 22 which are arranged vertically opposite to each other, and the fixed end 21 supports and is fixedly connected to the pressing end 12;

[0042] The vibration-damping part 3 is hollow; the vibration-damping part 3 has a top wall 31 and a bottom wall 32 which are vertically opposite to each other, and a surrounding wall 33 connecting the top wall 31 and the bottom wall 32; the top wall 31 is provided with a mounting opening 311 for the mounting end 22 to extend into the vibration-damping part 3; there is a gap between the mounting end 22 and the periphery of the mounting opening 311 and the surrounding wall 33; an elastic structure 321 is protruded from the bottom wall 32; and

[0043] The buffer gasket 4 is sandwiched between the mounting end 22 and the elastic structure 321 .

[0044] It can be understood that the pressure end 11 of the weighing rod 1 is used to bear the weight of the entire intelligent cooking device (the working state also includes the weight of the ingredients in the mixing container 200 and the impact force received by the intelligent cooking device during operation), and the pressure end 12 is connected to the fixed end 21 of the support leg 2 to transfer the weight to the support leg 2 and the vibration reduction part 3. The middle section of the weighing rod 1 is provided with a strain gauge 13 to detect the deformation of the weighing rod 1 and accurately obtain the current total weight of the intelligent cooking device (or convert it into the current weight of the ingredients) based on the deformation. For example but not limited to, the pressure end 11 and the pressure end 12 are respectively provided with screw holes that penetrate in the up and down directions, and the bottom of the base 100 and the fixed end 21 are respectively provided with connecting holes corresponding to the screw holes to realize the screw locking of the two ends of the weighing rod 1; of course, in other embodiments, the pressure end 11 and the pressure end 12 can also be fixed to the base 100 and the support leg 2 by snapping, and the present design is not limited to this.

[0045] In this embodiment, the support leg 2 is made of plastic material, which not only ensures reliable structural connection but also has a certain material elasticity; and the vibration damping part 3 is preferably made of silicone material. It can be understood that silicone is a material widely used in the field of vibration damping in the prior art, and has the advantages of being easy to obtain and having good elasticity. In addition, it is easy to understand that the support leg 2 and the vibration damping part 3 are clamped and fixed. Specifically, the mounting end 22 includes a clamping section 222 and a connecting section 221 connecting the clamping section 222 and the fixed end 21. The radial size of the clamping section 222 is larger than the size of the connecting section 221 and the mounting opening 311, so that during assembly, the clamping section 222 squeezes the mounting opening 311 and deforms to be clamped into the vibration damping part 3. It should be noted here that after the assembly is completed, there are gaps between the clamping section 222 and the surrounding wall 33, and between the connecting section 221 and the periphery of the mounting opening 311, so that horizontal space is reserved for the support leg 2; for example but not limited to, the hardness range of the silicone used in the vibration damping part 3 is 50 to 80 degrees, so that the vibration damping part 3 can ensure the reliability of its assembly with the support leg 2 on the basis of ensuring elasticity; in particular, in order to enhance the friction between the vibration damping part 3 and the placement surface of the intelligent cooking device, anti-slip textures can be added to the bottom surface of the bottom wall 32 of the vibration damping part 3.

[0046] It can be understood that the elastic structure 321 protruding from the bottom wall 32 can better buffer the impact force in the up and down directions on the support leg 2, and the buffer gasket 4 is introduced between the elastic structure 321 and the mounting end 22 to achieve surface contact between the mounting end 22 and the elastic structure 321, so that the support leg 2 can slide regularly in the vibration reduction part 3 and reduce its movement amplitude. Specifically, when assembling the vibration reduction foot 300, the buffer gasket 4 is first placed in the vibration reduction part 3, and the weighing scale rod 1 and the support leg 2 are fixed, and then the mounting end 22 of the support leg 2 is inserted into the vibration reduction part 3, so that the buffer gasket 4 can be clamped between the mounting end 22 and the elastic structure 321, which is convenient to assemble and disassemble, and improves the convenience of user replacement or maintenance. For example, but not limited to, in this embodiment, the buffer gasket 4 is made of metal material. In other words, the buffer gasket 4 is a metal sheet that is cheap and easy to obtain. In this way, the overall cost of the vibration reduction foot 300 can be effectively reduced. It should be noted that the present design is not limited to this. In other embodiments, in order to better realize the function of the buffer gasket 4, the buffer gasket 4 may also be made of other materials to ensure that the friction coefficient of the surface connected to the mounting end 22 is smaller than the surface connected to the rest of the elastic structure 321.

[0047] The technical solution of the present invention is to set a vibration-damping part 3 that movably wraps the bottom of the support leg 2. The bottom wall 32 of the vibration-damping part 3 is provided with an elastic structure 321 for buffering the vertical impact force exerted on the support leg 2, and a horizontal gap is present between the support leg 2 and the vibration-damping part 3, so that the support leg 2 can slide horizontally in the vibration-damping part 3 when subjected to the horizontal impact force, that is, the support leg is firstly damped by the elasticity of the surrounding wall 33 of the vibration-damping part 3, and after the vibration-damping part 3 reaches the maximum deformation state, it slides together with the support leg 2 to reduce vibration; in addition, a buffer gasket 4 clamped between the bottom of the support leg 2 and the elastic structure 321 is introduced to achieve surface contact between the support leg 2 and the elastic structure 321, and on the basis of not affecting the vertical buffering of the elastic structure 321, the regularity and smoothness of the horizontal sliding of the support leg 2 are enhanced, thereby reducing the shaking amplitude of the intelligent cooking device during operation, so that the vibration-damping base foot 300 achieves a better vibration-damping effect.

[0048] In this embodiment, the elastic structure 321 includes a plurality of circular protrusions arranged at intervals on the bottom wall 32; it can be understood that the impact force generated by the intelligent cooking device during operation may be in any direction, that is, the impact force on the support leg 2 may be in any direction. In this way, the elastic structure 321 is set as a combination of circular protrusions, which can achieve elastic buffering of impact forces in any direction and effectively ensure the vibration reduction effect. For example, but not limited to, the height range of the circular protrusions is 1.5mm to 3mm, preferably 2mm, and the interval range between any two adjacent circular protrusions is 3mm to 5mm, preferably 4mm, so as to improve the reliability and uniformity of the contact between it and the buffer gasket 4 on the basis of ensuring the elastic deformation effect; of course, in other embodiments, the height of the circular protrusions and the interval between adjacent circular protrusions can also be specific to other values, and the present design is not limited thereto. It should be noted that the present design is not limited thereto. In other embodiments, the elastic structure 321 includes a plurality of annular ribs arranged at intervals with the center of the bottom wall 32 as the center of the circle.

[0049] In this embodiment, the mounting end 22 is cylindrical and the surrounding wall 33 is annular. It can be understood that the cylindrical or annular shape is a widely used design shape in the field of vibration reduction in the prior art, which is conducive to buffering the impact force that may be received in all directions to ensure a better vibration reduction effect.

[0050] Optionally, the gap between the clamping section 222 and the surrounding wall 33 is smaller than the gap between the connecting section 221 and the periphery of the mounting opening 311. With such a configuration, when the horizontal sliding amplitude of the support leg 2 is large, the edge of the clamping section 222 first contacts the surrounding wall 33 of the vibration reduction part 3, and the surrounding wall 33 begins to play a vibration reduction and buffering role. It is easy to understand that compared with the periphery of the mounting opening 311, the surface of the surrounding wall 33 is flat and the contact area is large, which can achieve a better vibration reduction effect. Without loss of generality, in this embodiment, the movement distance of the clamping section 222 from contacting one side of the surrounding wall 33 to moving to contacting the other radial side of the surrounding wall 33 ranges from 2.5mm to 5mm, preferably 3mm. It can be understood that with such a configuration, while ensuring that the support leg 2 can slide horizontally in the vibration reduction part 3, it is prevented from sliding too far, which causes the horizontal movement amplitude of the intelligent cooking device to be too large during operation. In addition, it should be noted that in the technical solution of the present invention, in order to better improve the horizontal vibration reduction effect of the vibration reduction part 3, an elastic structure 321 may also be additionally protruded on the periphery of the mounting opening 311 and / or the surrounding wall 33, that is, an elastic structure 321 is provided at the position where the vibration reduction part 3 and the support foot 2 may contact.

[0051] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
