[0025] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0026] Reference below Figure 1 to Figure 2 A compressor 100 according to an embodiment of the first aspect of the utility model is described. The compressor 100 includes a base 110, a soft foot pad 120 and an elastic member 130. The base 110 has a foot 111. The soft foot pad 120 is sleeved on the outer peripheral wall of the foot 111. The elastic member 130 is sleeved on the outer peripheral wall of the soft foot pad 120.

[0027] Specifically, the compressor 100 has a base 110, and the base 110 has four feet 111. A soft pad 120 with relatively low hardness is mounted on the feet 111, and then an elastic member 130 is mounted on the soft pad 120. According to the vibration frequency of the compressor 100, the size and elastic coefficient of the elastic member 130 are designed to minimize the vibration transmitted from the compressor 100 to the housing; at the same time, the soft pad 120 is arranged between the feet 111 and the elastic member 130 to avoid hard contact between the feet 111 and the elastic member 130, thereby reducing the vibration transmission from the compressor 100 to the housing (not shown in the figure) and avoiding the buzzing noise generated by the compressor 100 and the housing due to resonance.

[0028] Compared with the simple use of soft foot pads 120 in the prior art, if the hardness of the soft foot pads 120 is high, the shock absorption effect is not good; if the hardness of the soft foot pads 120 is low, it is not enough to support the weight of the compressor 100, and there is only one layer of soft foot pads 120 between the compressor 100 and the outer shell, the vibration of the compressor 100 will still be transmitted to the outer shell, and the present application arranges an elastic member 130 outside the soft foot pads 120, which has a certain hardness to support the weight of the compressor 100, and at the same time, the soft foot pads 120 and the elastic member 130 are arranged between the compressor 100 and the outer shell, so that the amount of vibration transmitted to the outer shell is reduced.

[0029] It is understandable that the number of the base feet 111 may also be other numbers, such as six, and no specific limitation is made herein.

[0030] In some specific embodiments of the present invention, reference Figure 1-2 The hardness of the elastic member 130 is greater than that of the soft pad 120, ensuring that the support supporting the compressor 100 has a certain axial stiffness and shear stiffness, which can not only extend the service life of the soft pad 120, but also reduce the natural frequency of the support formed by the soft pad 120 and the elastic member 130, thereby avoiding the resonance frequency of the compressor 100 and the casing.

[0031] In some specific embodiments of the present invention, reference Figure 1-2 The elastic member 130 is a conical spring with a simple structure and easy installation.

[0032] In some specific embodiments of the present invention, reference Figure 1-2 The outer diameter of the bottom of the conical spring is smaller than the outer diameter of the top, which meets the elasticity requirements and saves material costs.

[0033] In some specific embodiments of the present invention, reference Figure 1-2 A gasket 140 is also sleeved on the foot 111 , and the gasket 140 is located between the soft foot pad 120 and the base 110 . The elastic member 130 abuts against or is connected to the gasket 140 to prevent the elastic member 130 from wearing the bottom plate of the base 110 .

[0034] In some specific embodiments of the present invention, a shock-absorbing sleeve (not shown in the figure) is provided on the outer side of the casing of the compressor 100, and the shock-absorbing sleeve is provided with a plurality of avoidance openings to avoid hard contact between the casing of the compressor 100 and adjacent parts, thereby further reducing the transmission of vibration of the compressor 100 to adjacent parts.

[0035] In some specific embodiments of the present invention, a convex portion is provided on the outer peripheral wall of the shock-absorbing sleeve to reduce the contact area between the compressor 100 and adjacent parts, further reduce the vibration of the compressor 100 transmitted to the adjacent parts, and at the same time have a certain buffering function.

[0036] In some specific embodiments of the present invention, the protrusion has a pointed portion, which further reduces the contact area between the compressor 100 and adjacent parts.

[0037] In some specific embodiments of the utility model, two shock-absorbing sleeves are provided, and the two shock-absorbing sleeves are respectively located on the upper and lower sides of the casing. The two shock-absorbing sleeves are fixedly connected, for example, by snap-fitting or by screws. The two shock-absorbing sleeves can fully cover the casing and can be quickly installed on the casing.

[0038] In some specific embodiments of the present invention, the soft foot pad 120 and the shock-absorbing sleeve are made of rubber, which has a long service life and low cost. The elastic member 130 is made of metal, such as steel.

[0039] An oxygen concentrator (not shown) according to an embodiment of the second aspect of the utility model comprises a housing and a compressor 100 according to any embodiment of the first aspect of the utility model, wherein the compressor 100 is fixedly installed in the housing.
