However, the following problems exist in the installation method: the clearance is uncontrollable between heating block and the callus on the sole, needs to adjust according to heating power, leads to if heating block and callus on the sole clearance too big, and is lower through heat radiation energy, is difficult to realize the big temperature variation of callus on the sole and changes hardness. If the gap is too small, the deformation of the foot pad in all directions is affected, and the vibration reduction effect of the foot pad is reduced. Moreover, the technical scheme needs to supply power with the introduced power supply heating block and independently control, so that the whole convenience degree is poor.

As shown in fig. 1 to 3, the compressor foot pad assembly in the present embodiment includes a foot pad main body 41 having one end engaged with the compressor main body 10 and the other end engaged with the base 20 for supporting the compressor main body 10; the piezoelectric energy harvester 30 is arranged on the compressor main body 10 and can capture energy along with the vibration of the compressor main body 10 during working; and a heating element 45 attached to the pad body 41 for heating the pad body 41; the heating element 45 in this embodiment is electrically connected to the piezoelectric energy harvester 30, and can obtain the electric energy of the piezoelectric energy harvester 30 to heat the foot pad body 41 when the compressor body 10 is in operation. And then adopt the compressor foot pad subassembly in this embodiment, through setting up in the heating element 45 that the callus on the sole main part 41 was laminated mutually, and supply power to heating element 45 at compressor main part 10 during operation through the piezoelectric energy harvester 30 of installing on compressor main part 10, make heating element 45 heat callus on the sole main part 41, and then can soften callus on the sole main part 41, reduce the hardness of callus on the sole 40, and in the compressor transportation, the electric energy that piezoelectric energy harvester 30 was caught is less than the electric energy of compressor during operation, and then the softening of callus on the sole main part 41 is limited, and then the hardness of callus on the sole 40 has been guaranteed, make the compressor in operation and transportation, compressor foot pad subassembly all can satisfy the damping requirement, vibration damping effect has been guaranteed.

In one variation of this embodiment, the piezoelectric harvester 30 is detachable from the base 20, and also uses the electrical energy generated by the base 20 during operation of the compressor. Or the piezoelectric traps are arranged on the base 20 and the compressor body 10, and the effects of heating the foot pad 40 by generating electric energy, softening the foot pad 40 and reducing the hardness of the foot pad 40 can also be achieved.

In the present embodiment, the piezoelectric energy harvester 30 is made of a piezoelectric material, and can directly capture the vibration energy of the compressor. The piezoelectric energy harvester 30 in the embodiment is a general component which is widely applied, is mostly used in areas such as forests or seabed and the like which are difficult to intervene manually, can capture energy meeting the electric quantity requirement by utilizing natural excitation such as branch vibration or seawater beating caused by wind blowing, and has a great amount of verification on reliability.

The working principle is as follows: the molecules of the piezoelectric crystal are uniformly distributed in the piezoelectric crystal, and no electric charge is generated on the surfaces of the upper electrode and the lower electrode of the crystal. When the compressor runs, when the piezoelectric crystal is stretched by external force, the interior of the crystal is polarized, and charges with opposite polarities are generated on the surfaces of the upper electrode and the lower electrode of the crystal; when the crystal is compressed by external force, charges with the same polarity are generated on the surfaces of the upper electrode and the lower electrode of the crystal. When the external force disappears, the charges disappear gradually and return to the initial state. The phenomenon that the piezoelectric material maintains an initial state by resisting the same amount of positive and negative charges generated by the change of the material is called a positive piezoelectric effect.

And the compressor uses in the outer machine operation of air conditioner in this embodiment, and compressor vibration energy is very big, pastes piezoelectric material on compressor lower part or compressor base 20, when the displacement appears in the compressor operation, thereby piezoelectric material can atress warp inside production electric energy, directly supplies with the electric energy callus on the sole 40 heating wire etc. thereby heats callus on the sole 40 and makes the reduction of callus on the sole 40 hardness.

The pad body 41 in this embodiment is made of rubber, which has the advantage of low cost.

Preferably, the foot pad main body 41 and the heating element 45 in the embodiment are integrally formed, so that the effect of the heating element 45 for heating the foot pad main body 41 is further improved, the foot pad 40 is softened, and the vibration reduction effect is improved. And meanwhile, the reliability is better.

Preferably, the difference between the fixed frequency value of the piezoelectric energy harvester 30 and the average frequency value of the compressor operation is less than 20hz, so that the compressor can more easily resonate the energy harvester during operation, and the resonance causes greater stress in the energy harvester, thereby generating greater electrical energy for the heating element 45 to operate. Preferably, the fixed frequency value of the piezoelectric harvester 30 is equal to the average frequency value of the compressor operation.

The number of the piezoelectric harvesters 30 in this embodiment is more than one, and the generated electric energy is more sufficient.
