Because the vacuum pump 300 is a cylinder structure, therefore, the damping sleeve 200 is also a cylinder structure, the elastic arms 210 are disposed on two opposite sides of the damping sleeve 200, that is, the elastic arms 210 disposed on two opposite sides of the damping sleeve 200 are symmetrically disposed with the axis of the damping sleeve 200 as the center, the first side surface 110 of the base 100 is disposed with one of the grooves 130, so that the damping sleeve 200 is partially disposed in the groove 130, and thus the elastic arms 210 are just outside the groove 130, therefore, the mounting post 120 on the first side surface 110 does not need to be set to be too long, and the elastic arms 210 can be connected with the mounting post 120, thereby making the overall structure more reasonable, having a relatively smaller overall volume, and being beneficial to saving the space in the storage chamber.

In order to improve the connection strength between the damping sleeve and the base, as shown in fig. 2 and 3, at least two elastic arms 210 are respectively disposed on two opposite sides of the outer wall of the damping sleeve 200 provided in the embodiment of the present invention, at least two mounting columns 120 are respectively disposed at two ends of the first side surface 110, and the mounting holes 211 on the elastic arms 210 are correspondingly sleeved on the mounting columns 120 one by one. Through set up two at least elastic arms 210 in the both sides relative on shock attenuation cover 200 outer wall, when a plurality of elastic arms 210 were all taut, can increase elastic arm 210's the power that resets, amplitude when further reducing shock attenuation cover 200 vibrations to can further promote the shock attenuation effect.

In some embodiments, the base 100 and the inner wall of the storage room may be fixedly connected by screws, etc., so as to facilitate the detachment of the base 100, and facilitate the repair or replacement.

In some embodiments, the base 100 is integrally formed on an interior wall of the storage compartment. With base 100 integrated into one piece in the storeroom, the inner bag that forms the storeroom promptly directly passes through injection moulding with base 100 to can reduce the connection structure between the inner wall of base 100 and storeroom, overall structure is more firm.

In some embodiments, as shown in FIG. 2, the shock absorbing sleeve 200 and the resilient arm 210 are made of the same material and are integrally formed. The damping sleeve 200 and the elastic arm 210 can be made of elastic rubber materials, the materials have good elasticity and can better absorb vibration, so that the damping effect is achieved, and the damping sleeve and the elastic arm are integrally formed, so that the stability of the whole structure is improved.
