[0034] The utility model relates to a compressor damping device, is provided with mass block 4 through connecting rod 3 on the outside of compressor casing 1 or liquid accumulator 2, when the vibration of compressor casing 1 work appears, will drive connecting rod 3 vibration, and then the mass block 4 of setting in the end of connecting rod 3 also vibrates, but because mass block 4 and compressor casing 1 are driven connection through connecting rod 3, so the vibration of mass block 4 is lagging behind the vibration of compressor casing 1, namely when the compressor is put into operation, mass block 4 maintains the original motion state due to inertia effect, will form the phase difference with the vibration of compressor casing 1, thereby effectively reducing the vibration of compressor.

[0037] Preferably, as shown in Figures 3-6 In this embodiment, the damping system includes at least one damping element 5, and the damping element 5 is arranged on the outer periphery side of the mass block 4. The number of damping elements 5 can be determined according to actual conditions. For example, when the amplitude of the mass block 4 is large, one damping element 5 cannot meet the demand for reducing the amplitude of the mass block 4, so two or more damping elements 5 are sleeved together to jointly reduce the amplitude of the mass block 4.

[0038] Further, in the embodiment, the damping element 5 is made of rubber material. In other embodiments, the damping element 5 can also be made of other materials with excellent damping performance to ensure that the damping element 5 can fully play a damping effect. In the embodiment, the specific shape and material of the damping element 5 are not limited to a specific type, as long as it has good damping performance and durability.

[0039] To better describe the structure of the damping element 5, the application discloses two structures of the damping element 5, as follows:

[0040] The first structure:

[0041] As shown in Figure 3 , Figure 5 , Figure 6 , the damping element 5 includes a bottom sleeve 501 and a top damping ring 502, the bottom sleeve 501 is cylindrical, the top damping ring 502 is conical, and the bottom sleeve 501 is fixedly connected with the top damping ring 502; the damping element 5 is trumpet-shaped; the cylindrical bottom sleeve 501 is sleeved on the outer circumferential surface of the connecting rod 3, and the top damping ring 502 is located on the outer circumferential side of the mass block 4; when the mass block 4 vibrates, the mass block 4 contacts the top damping ring 502, and the top damping ring 502 weakens the vibration of the mass block 4.

[0042] Further, the bottom sleeve 501 is sleeved on the outer circumferential surface of the connecting rod 3 through interference fit; the diameter specification of the end of the top damping ring 502 away from the bottom sleeve 501 is greater than the size specification of the mass block 4.

[0043] Further, the bottom sleeve 501 and the top damping ring 502 are an integral piece, or are fixedly connected in other ways; for example, bonding and the like. Correspondingly, the bottom sleeve 501 can also be fixed on the outer circumferential surface of the connecting rod 3 in other ways; for example, clamp connection, screw connection and the like.

[0044] The second structure:

[0045] As shown in Figure 4 , the damping element 5 includes a damping sleeve, the damping sleeve is sleeved on the outer circumferential side of the mass block 4 and the connecting rod 3, and the end of the damping sleeve away from the mass block 4 is fixed on the compressor shell 1 or the liquid accumulator 2; the diameter specification of the damping sleeve is greater than the size specification of the mass block 4.

[0046] Further, to facilitate the installation of the damping element 5, the compressor shell 1 or the liquid accumulator 2 is provided with a connecting lug 6, and the end of the damping sleeve away from the mass block 4 is sleeved on the connecting lug 6.

[0047] Further, to avoid the damping sleeve from falling off the connecting lug 6 when the compressor shell 1 works with vibration, the damping sleeve can be sleeved on the connecting lug 6, and then the end of the damping sleeve is fixed on the connecting lug 6 by means of a clamp connection, screw connection or the like.

[0048] In the structures of the two damping elements 5, the diameter specification of the damping sleeve and the diameter specification of the bottom sleeve 501 can be determined according to the vibration amplitude of the mass block 4, that is, the diameter of the damping sleeve and the diameter of the bottom sleeve 501 can be the same as the maximum amplitude of the mass block 4, so that the mass block 4 is tightly matched with the damping element 5 when the mass block 4 reaches the maximum amplitude, and the vibration amplitude of the mass block 4 is reduced by the damping element 5.

[0049] To achieve the above object or other objects, the utility model discloses a kind of compressor, and the compressor includes the compressor damping device described above.

[0050] The compressor damping device and the compressor of the utility model are related to the technical field of compressor, and have the following beneficial effects:

[0053] Then, when the compressor works, the compressor will vibrate, and the connecting rod 3 also vibrates, and the mass block 4 arranged at the end of the connecting rod 3 also vibrates, but since the mass block 4 maintains the original motion state due to inertia when the vibration of the connecting rod 3 is transmitted to the mass block 4, the mass block 4 will form a phase difference with the vibration of the compressor shell 1, thereby effectively reducing the vibration of the compressor shell 1.

[0054] Finally, when the connecting rod 3 drives the mass block 4 to vibrate, the longer the length of the connecting rod 3 is, the larger the vibration amplitude of the mass block 4 will be, and when the vibration amplitude of the mass block 4 is too large, the mass block 4 will contact with the damping element 5, and the damping element 5 will fully play its role of absorbing and consuming excess energy, thereby effectively restraining the vibration amplitude of the mass block 4, avoiding that the mass block 4 applies too large pressure to the connecting rod 3 due to too large vibration amplitude, and prolonging the service life of the connecting rod 3.

[0055] ​The utility model relates to a compressor damping device and compressor, set up mass 4 on compressor casing 1 or liquid accumulator 2, rely on inertia of mass 4 to make the vibration of mass 4 and the vibration of compressor form phase difference, thereby the vibration of compressor is reduced. The design of mass 4 fully considers the characteristic of compressor vibration, especially in-depth optimization is carried out to the influence of rotary vibration, can provide reverse force when vibration produces, realizes remarkable damping effect. Simultaneously set up damping element 5, when the amplitude of mass 4 is too big and causes big pressure to connecting rod 3, mass 4 and damping element 5 touch, and damping element 5 is used to absorb and consume the excess energy of mass 4 in the vibration process, prolongs the service life of connecting rod 3. The utility model relates to a compressor damping device and compressor, can effectively reduce the vibration of compressor, improves the operation stability and reliability of compressor.
