[0028] The present disclosure also provides an air conditioner, which includes the aforementioned compressor.

[0029] The compressor exhaust structure, compressor and air conditioner provided by the present disclosure have the following beneficial effects:

[0030] 1. The present invention provides a first and a second accommodating chamber on a cylinder body, and a first moving part is provided in the first accommodating chamber, a second moving part is provided in the second accommodating chamber, and an exhaust chamber is provided on the cylinder body, so that the exhaust gas of the compression chamber first passes through the first accommodating chamber to push the first moving part to move, so as to open the exhaust chamber for exhaust. During the exhaust process, the gas in the exhaust chamber can also enter the second accommodating chamber to push the second moving part to move so as to further act on the first moving part with the gas, so that the first moving part closes the exhaust chamber. The second moving part plays a role of comparing pressure, and can guide the gas to the back of the first moving part when the pressure is too high to drive it to close the exhaust chamber. Through the two valve block structures, by comparing the pressure, it is ensured that the valve opening and closing are in a dynamic balance, thereby ensuring that during high-frequency operation, the valve port will not be normally opened due to excessive pressure acting on the exhaust slider, effectively preventing the reduction of high-frequency cooling capacity, and solving the problem of low high-frequency capacity of the compressor due to delayed closing of the exhaust valve plate under high-frequency operation of the original structure. The slide valve disclosed in the present invention adopts a self-control structure, which is divided into an exhaust slider and a comparative pressure slider. At the same time, a flow channel groove is opened on the slide. The rotor will be turned on at the beginning of compression, and the exhaust process will start when the pressure is greater than the spring set pressure. When the high frequency is running, the exhaust pressure increases sharply. At this time, the exhaust cavity absorbs part of the exhaust noise. At the same time, the high pressure pushes the comparative pressure slider to move, and the exhaust port is pushed to close under the cooperation of the exhaust slider spring force, so as to keep the compressor running in dynamic balance at the set optimal pressure and keep the high frequency capacity from attenuation.

[0031] 2. The present invention can ensure that the refrigerant will not directly enter the first accommodating chamber and be discharged by opening a connecting groove on the sliding vane, effectively delaying the exhaust time, improving the compression capacity, avoiding liquid compression during the compression process, and improving the reliability of the compressor. The side opening of the sliding vane delays the time when the compressor starts to compress and exhaust. In the closed cavity with high temperature and high pressure, the liquid refrigerant will be vaporized instantly, and there will be no liquid compression during exhaust.

[0032] 3. The moving parts of the present invention are made of PEEK (polyetheretherketone) material, and a high-rigidity spring slider structure is used to replace the previous elastic valve plate baffle structure, which improves the reliability of compressor operation; the hard contact of the exhaust port crescent groove is replaced by a spring slider soft contact, which reduces the exhaust shock load and makes the compressor run more smoothly; the self-control slide valve structure made of PEEK (polyetheretherketone) is used. PEEK material has good toughness and can absorb the exhaust shock load. The contact stress is also smaller than that of metal valve plates, which greatly reduces the exhaust noise;

[0033] 4. The present invention also provides a resonance chamber on the cylinder body, and the resonance chamber is connected between the exhaust chamber and the second accommodating chamber, so that the gas can be resonated and silenced before entering the comparative pressure channel from the exhaust chamber, thereby improving the vibration reduction effect on the cylinder.

[0045] like Figure 1-4d As shown, the present disclosure provides a compressor exhaust structure, which includes:

[0046] Cylinder 1, cylinder 1 includes a cylinder body 2 and a compression chamber 3, the compression chamber 3 is located on the radial inner side of the cylinder body 2, and a first accommodating chamber 4, a second accommodating chamber 5 and an exhaust chamber 6 are arranged on the cylinder body 2. The compressor exhaust structure also includes a first moving component 7 and a second moving component 8. The first moving component 7 is arranged in the first accommodating chamber 4, and the second moving component 8 is arranged in the second accommodating chamber 5. The gas in the compression chamber 3 can enter the first accommodating chamber 4 and act on one end of the first moving component 7 to push the first moving component 7 to move to open the exhaust chamber 6 and exhaust from the exhaust chamber 6. The gas in the exhaust chamber 6 can also enter the second accommodating chamber 5 and push the second moving component 8 to move, so that the gas in the second accommodating chamber 5 can reach and act on the other end of the first moving component 7 to push the first moving component 7 to move and close the exhaust chamber 6.

[0047] The present invention provides a first and a second accommodating chamber on a cylinder body, and a first moving component is provided in the first accommodating chamber, a second moving component is provided in the second accommodating chamber, and an exhaust chamber is provided on the cylinder body, so that the exhaust gas of the compression chamber can first pass through the first accommodating chamber to push the first moving component to move, so as to open the exhaust chamber for exhaust. During the exhaust process, the gas in the exhaust chamber can also enter the second accommodating chamber to push the second moving component to move so as to further act on the first moving component with the gas, so that the first moving component closes the exhaust chamber. The second moving component plays a role of comparing pressure, and can guide the gas to the back of the first moving component when the pressure is too high to drive it to close the exhaust chamber. Through the two valve block structures, by comparing the pressure, it is ensured that the valve opening and closing are in a dynamic balance, thereby ensuring that during high-frequency operation, the valve port will not be normally open due to excessive pressure acting on the exhaust slider, effectively preventing the reduction of high-frequency cooling capacity, and solving the problem of low high-frequency capacity of the compressor due to delayed closing of the exhaust valve plate under high-frequency operation of the original structure. The sliding valve disclosed in the present invention adopts a self-control structure, which is divided into an exhaust slider and a comparative pressure slider. At the same time, a flow channel groove is opened on the sliding vane. The rotor will only be turned on at the beginning of compression, and the exhaust process will not start until the pressure is greater than the spring set pressure. When operating at a high frequency, the exhaust pressure increases sharply. At this time, the exhaust chamber absorbs a part of the exhaust noise. At the same time, the high pressure pushes the comparative pressure slider to move, and the exhaust port is pushed to close in cooperation with the spring force of the exhaust slider, so as to keep the compressor running in dynamic balance at the set optimal pressure and keep the high-frequency capacity from attenuation.

[0048] The present invention cancels the existing exhaust structure (using elastic valve plate and baffle) on the upper flange, and opens a self-control valve block structure on the cylinder surface. Compared with the normal mass production that relies on the elasticity of the valve plate material itself to open and close the exhaust valve port, the present invention can dynamically balance the opening and closing of the valve port of the compressor during high-frequency operation by comparing the exhaust pressure with the spring force of the spring slide valve structure, ensuring that it is always in a highly efficient state without causing low high-frequency capacity. Compared with the traditional upper flange valve plate and valve plate baffle exhaust structure, the present invention solidifies the exhaust structure of the compressor on the cylinder surface and adopts a PEEK material valve block structure. On the one hand, it gets rid of the traditional reliance on the elasticity of the valve plate material itself to control the opening and closing, and adopts a controllable valve block structure to improve the operating reliability of the compressor; on the other hand, it controls the state of the compressor in high-frequency operation. In normal mass production, the valve plate in high-frequency operation will not have time to close before the next intake compression cycle begins. The present invention uses two valve block structures to compare pressures to ensure that the valve port opening and closing are in a dynamic balance.

[0049] In the existing rotor compressor exhaust structure, the exhaust pressure pushes the valve plate to exhaust, and the lift of the exhaust valve plate is limited by the valve plate baffle. However, in the development of related projects and compressor reliability tests, it was found that the exhaust valve plate and the valve plate baffle broke from time to time. Secondly, the valve plate slapping sound caused the compressor sound quality to be poor. At the same time, when the compressor is running at high frequency, the large exhaust pressure causes the exhaust valve port to open too large, affecting the high-frequency capacity of the compressor and causing capacity attenuation. The present disclosure can achieve a dynamic balance of pressure at both ends of the exhaust slider through a pressure comparison system during the exhaust stage of the compressor, especially the high-frequency stage, thereby improving the energy efficiency of the compressor and preventing high-frequency capacity attenuation. At the same time, considering the impact load and slapping noise of the exhaust, the present disclosure adopts PEEK (polyetheretherketone) material, which greatly reduces the impact of noise and impact load, and also improves the reliability of the compressor operation.

[0050] In some embodiments, the first accommodating chamber 4 includes a first end 41 and a second end 42. The first end 41 can be connected to the compression chamber 3 to introduce gas from the compression chamber 3. The gas can push the first moving component 7 to move toward the second end 42. The second end 42 is opposite to the first end 41. A first circulation channel 44 is formed between the first end 41 and the first moving component 7. The first circulation channel 44 can be connected to the exhaust chamber 6. This is the preferred structural form of the first accommodating chamber of the present disclosure, that is, the first end is used to communicate with one end of the compression chamber, and the second end is the abutment end of the first moving component. The first moving component is driven by the gas in the compression chamber to move toward the second end. When it moves to the position of the exhaust chamber, the first circulation channel can be connected to the exhaust chamber, thereby forming exhaust. However, when the exhaust pressure is too large, the gas pressure of this part acts on the lower end of the first moving component through the second moving component, thereby driving the first moving component to move upward, closing the exhaust chamber, effectively forming a dynamic balance, preventing the valve port from being normally open, and reducing the attenuation of high-frequency cooling capacity.

[0051] In some embodiments, the first accommodating chamber 4 also includes a third end 43, and the exhaust chamber 6 is connected to the third end 43. When the first moving component 7 moves to a position between the first end 41 and the exhaust chamber 6, or the first moving component 7 moves to be opposite to the exhaust chamber 6, the connection between the first circulation channel 44 and the exhaust chamber 6 can be blocked by the first moving component 7. When the first moving component 7 moves to a position between the second end 42 and the exhaust chamber 6, the first moving component 7 does not block the connection between the first circulation channel 44 and the exhaust chamber 6, so that the first circulation channel 44 is connected to the exhaust chamber 6. The first accommodating chamber of the present invention is also connected to the exhaust chamber through a third end, so that the first circulation channel is effectively connected with the exhaust chamber at the third end, and the first moving component moves between the first end and the exhaust chamber to seal the exhaust chamber, and moves between the second end and the exhaust chamber to open the exhaust chamber. The pressure on both sides of the first moving component can be connected through the exhaust chamber, and the exhaust chamber is connected to the second accommodating chamber. After the pressure in the second accommodating chamber is greater than the preset pressure, it enters the other end of the first moving component and pushes the first moving component to close the exhaust chamber, effectively realizing the dynamic balance of the exhaust chamber not being often open, ensuring that the cooling capacity does not decay during high-frequency operation.

[0052] In some embodiments, the exhaust cavity 6 is provided with an exhaust port 61 to exhaust gas outward from the exhaust port 61; and / or the third end 43 is located at a side close to the first end 41 relative to the second end 42. This is a further preferred structural form of the exhaust cavity of the present disclosure, and the exhaust port provided in the exhaust cavity can effectively exhaust gas toward the outside of the compressor, preferably to the inside of the compressor housing through a flange; the third end is preferably located at one side of the first end, so that when the first moving component moves in the first accommodating cavity, the first flow channel can be switched between being connected to and not connected with the exhaust cavity.

[0053] In some embodiments, the first accommodating chamber 4 further includes a third chamber 45 between the first moving component 7 and the second end 42, and a first damping structure 91 is further provided in the third chamber 45, one end of the first damping structure 91 is connected to the first moving component 7, and the other end is connected to the second end 42. The present disclosure also provides an initial opening force to the first moving component through the first damping structure by means of the third chamber formed on the other side of the first moving component and the first damping structure provided in the third chamber; and the third chamber can introduce gas from the second accommodating chamber to act on the other end of the first moving component to drive the first moving component to move together with the damping force to close the exhaust chamber (the gas pressure + the damping force jointly drive the first moving component to close the exhaust chamber).

[0054] In some embodiments, the first damping structure 91 is a first spring, and there is at least one first spring; or the first damping structure 91 is a first hydraulic piston structure. This is the preferred structural form of the first damping structure disclosed in the present invention, and the spring structure can effectively provide the initial resistance of the gas pushing the first moving part into the first circulation channel, ensuring that the pressure in the compression chamber can be exhausted only after reaching a certain pressure, and providing the restoring force for the first moving part to reset; the hydraulic piston structure can also provide the initial resistance and the restoring force to ensure that the first moving part returns to the initial state.

[0055] In some embodiments, when the pressure of the gas entering the first circulation channel 44 is greater than the resistance of the first damping structure 91, the first moving component 7 is pushed to move toward the second end 42, thereby opening the exhaust chamber 6; and / or, the first moving component 7 is an exhaust slider. This is the preferred relationship among the first circulation channel, the first moving component, and the first damping structure of the present disclosure. The first damping structure provides the initial resistance of gas exhaust, ensuring that the gas is exhausted after reaching a certain pressure; the movement of the first moving component can play an effective exhaust role, and is preferably an exhaust slider.

[0056] In some embodiments, the second accommodating chamber 5 includes a fourth end 51, a fifth end 52, and a sixth end 53, and a second circulation channel 54 is formed between the fourth end 51 and the second moving component 8, and the second circulation channel 54 can communicate with the exhaust chamber 6 so that the gas enters the second circulation channel 54;

[0057] The second moving component 8 can move between the fourth end 51 and the fifth end 52. A connecting channel 55 is provided on the sixth end 53. The first accommodating chamber 4 also includes a third chamber 45 between the first moving component 7 and the second end 42. One end of the connecting channel 55 is connected to the third chamber 45, and the other end can be connected to the second circulation channel 54.

[0058] This is the preferred structural form of the second accommodating chamber disclosed in the present invention, a second circulation channel is formed between the second moving component and the fourth end, and a connecting channel is arranged on the third end, so that the gas in the second circulation channel in the second accommodating chamber can enter the third chamber through the connecting channel, and then act on the first moving component to control whether to close the exhaust chamber to achieve dynamic balance; whether the second circulation channel on one side of the second moving component of the present invention introduces gas requires that the gas pressure is greater than the set pressure and automatically pushes the second moving component to enter the second circulation channel, thereby effectively realizing that the exhaust chamber can be closed in time when the pressure is too high, so that the exhaust is in a dynamic equilibrium state, the exhaust is intermittent, and the cooling capacity is prevented from decaying.

[0059] In some embodiments, the fourth end 51 is opposite to the fifth end 52, and the sixth end 53 is located on one side of the fourth end 51. This is a preferred structural form of the fourth, fifth and sixth ends on the second accommodating cavity of the present disclosure, that is, the connecting channel provided on the sixth end is located on the side of the fourth end, so that when the second moving component moves in the second accommodating cavity, the second circulation channel can be switched between being connected with the connecting channel and being disconnected.

[0060] In some embodiments, the gas in the first circulation channel 44 acts on the seventh end 71 of the first moving component 7, and the gas that enters the third chamber 45 in sequence through the second circulation channel 54 and the connecting channel 55 can act on the eighth end 72 of the first moving component 7, so as to drive the first moving component 7 to move and close the exhaust chamber 6, and the seventh end 71 and the eighth end 72 are two opposite ends of the first moving component 7. This is a further preferred structural form of the present disclosure, that is, the first moving component includes the seventh end and the eighth end opposite to each other, and the exhaust pressure in the first circulation channel acts on the seventh end, and the feedback pressure entering the third chamber from the second accommodating chamber acts on the eighth end of the first moving component, thereby realizing the dynamic balanced driving movement of the first moving component.

[0061] In some embodiments, when the second moving component 8 moves to a position between the fourth end 51 and the connecting channel 55, the second moving component 8 can block the connection between the second circulation channel 54 and the third chamber 45. When the second moving component 8 moves to a position between the fifth end 52 and the connecting channel 55, the second moving component 8 does not block the connection between the second circulation channel 54 and the third chamber 45, so that the second circulation channel 54 is connected to the third chamber 45. The second accommodating chamber of the present disclosure is also connected to the connecting channel through the sixth end, so that the second circulation channel is effectively connected to the connecting channel at the sixth end, and the second moving component moves to the fourth end and the connecting channel to block the exhaust chamber, and moves to the fifth end and the connecting channel to open the connecting channel. The two-side force of the second moving component can connect the third chamber with the second accommodating chamber through the connecting channel. After the pressure in the second accommodating chamber is greater than the preset pressure, it enters the other end of the first moving component to push the first moving component to close the exhaust chamber, effectively realizing the dynamic balance of the exhaust chamber not being often open, and ensuring that the cooling capacity does not decay during high-frequency operation.

[0062] In some embodiments, a fourth cavity 56 is formed between the second moving component 8 and the fifth end 52 in the second accommodating cavity 5, and a second damping structure 92 is further disposed in the fourth cavity 56, one end of the second damping structure 92 is connected to the second moving component 8, and the other end is connected to the fifth end 52. The present disclosure also provides an initial opening force to the second moving component through the fourth cavity formed on the other side of the second moving component and the second damping structure disposed in the fourth cavity; the damping force can drive the second moving component to move to close the connecting channel.

[0063] In some embodiments, the second damping structure 92 is a second spring; there is at least one second spring; or the second damping structure 92 is a second hydraulic piston structure. This is the preferred structural form of the second damping structure disclosed in the present invention. The spring structure can effectively provide the initial resistance for the gas to push the second moving part into the second circulation channel, ensuring that the pressure entering the second circulation channel reaches a certain pressure (comparative pressure, to prevent the exhaust chamber from being always open due to excessive pressure. If it is less than the comparative pressure, the feedback pressure will not be provided through the second accommodating chamber. At this time, since the exhaust of the compression chamber itself will not be too high, it will not cause the exhaust chamber to be always open due to excessive pressure, nor will it cause a large attenuation of the cooling capacity). Only then can the connecting channel be opened to close the exhaust chamber, and provide a restoring force to reset the second moving part; the hydraulic piston structure can also provide initial resistance and a restoring force to ensure that the second moving part returns to its initial state.

[0064] If the spring structure cannot stably balance the pressure changes, the spring structure can be replaced with a hydraulic structure and processed into a hydraulic piston structure. The effect of the present disclosure can also be achieved by controlling the hydraulic pressure.

[0065] In some embodiments, when the gas pressure entering the second circulation channel 54 is greater than the resistance of the second damping structure 92, the second moving component 8 is pushed to move toward the fifth end 52, thereby opening the connecting channel 55; and / or, the second moving component 8 is a comparative pressure slider. This is the preferred relationship between the second circulation channel, the second moving component and the second damping structure of the present disclosure, and the second damping structure provides the initial resistance of gas exhaust to ensure that the gas reaches a certain pressure and feeds back pressure to the other side of the first moving component; the movement of the second moving component can play the role of effective pressure feedback, and is preferably a comparative pressure slider.

[0066] In some embodiments, a resonance chamber 10 is further included, and the resonance chamber 10 is arranged on the cylinder body 2, one end of the resonance chamber 10 is connected to the exhaust chamber 6, and the other end can be connected to the second accommodating chamber 5, so that the gas in the exhaust chamber 6 is introduced into the second accommodating chamber 5 through the resonance chamber 10. Preferably, the cross section of the resonance chamber is a "concave" structure. The present disclosure also uses a resonance chamber opened on the cylinder body, and the resonance chamber is connected and arranged between the exhaust chamber and the second accommodating chamber, so that the gas can be resonated and silenced before entering the comparative pressure channel from the exhaust chamber, thereby improving the vibration reduction effect on the cylinder.

[0067] In some embodiments, a comparative pressure air inlet channel 11 is further provided on the cylinder body 2, one end of the comparative pressure air inlet channel 11 is connected to the resonance chamber 10, and the other end is connected to the second accommodating chamber 5. Preferably, in some embodiments, there are multiple comparative pressure air inlet channels, and the multiple comparative pressure air inlet channels are parallel to each other. The present disclosure can introduce the gas pressure in the resonance chamber into the second flow channel through the comparative pressure air inlet channel opened on the cylinder body to provide comparative pressure.

[0068] In some embodiments, a slide 12 and a roller 13 are further included. A slide groove 21 is provided on the cylinder body 2. The slide 12 is located in the slide groove 21 and can reciprocate along the slide groove 21. The roller 13 is located in the compression chamber 3. The compression chamber 3 includes an exhaust chamber 2 31 located on the same side as the first moving component 7, with the slide 12 as the boundary.

[0069] The slide 12 includes a head and a tail, the head is connected to the roller 13, and the tail is located in the slide groove 21. A connecting groove 14 is provided on the slide 12 at a position relative to the tail and close to the head. The connecting groove 14 is opposite to and connected with the exhaust chamber 2 31. The gas in the exhaust chamber 2 31 can only be discharged when the connecting groove 14 at least partially enters the slide groove 21 and is connected with the first accommodating chamber 4.

[0070] The present invention can ensure that the refrigerant will not directly enter the first accommodating chamber and be discharged by opening a connecting groove on the sliding plate, effectively delaying the exhaust time, improving the compression capacity, avoiding liquid compression during the compression process, and improving the reliability of the compressor. The side opening of the sliding plate delays the time when the compressor starts to compress and exhaust. In the closed chamber with high temperature and high pressure, the liquid refrigerant will be vaporized instantly, and there will be no liquid compression during exhaust.

[0071] In some embodiments, the first moving part 7 is made of polyetheretherketone material; and / or, the second moving part 8 is made of polyetheretherketone material. The moving parts of the present disclosure are made of PEEK (polyetheretherketone) material, and a high-rigidity spring slider structure is used to replace the previous elastic valve plate baffle structure, which improves the reliability of compressor operation; the hard contact of the exhaust port crescent groove is replaced with a spring slider soft contact, which reduces the exhaust shock load and makes the compressor run more smoothly; a self-controlled slide valve structure made of PEEK (polyetheretherketone) is used. PEEK material has good toughness and can absorb the exhaust shock load. The contact stress is also smaller than that of a metal valve plate, which greatly reduces the exhaust noise.

[0072] Figure 4a As shown, the compressor takes in air from the suction port. When the roller runs to the suction end point, the compression stage begins. Considering that there may be a two-phase refrigerant state in the suction stage, the exhaust start time is delayed and the compressor runs to Figure 4bAt the beginning of exhaust, the compressor starts to exhaust, which avoids abnormal situations such as liquid compression during the operation of the compressor, which may cause damage to the compressor. At the beginning of exhaust, the gaseous refrigerant enters the exhaust chamber 6 from the vane exhaust channel (connecting groove 14), pushes the exhaust slider (first moving part 7) to move under high pressure, opens the exhaust valve, and starts to be discharged from the exhaust port 61 into the compressor housing, and a part of it enters the resonance chamber 10. The opening pressure of the comparison pressure slider (second moving part 8) is preset, such as Figure 4c When the incoming pressure is greater than the opening pressure, the comparative pressure slider moves, and the gaseous refrigerant enters the other end of the exhaust slider (the first moving component 7) from the resonance cavity 10 and the comparative pressure inlet. The exhaust slider is pushed to move under the combined force of the spring force of the first spring structure and the comparative pressure, and the valve opening is reduced. During the entire compressor suction and exhaust process, the dynamic balance of pressure is always maintained, so that the compressor can remain in an efficient working state.

[0073] The present disclosure also provides a compressor, which includes the compressor exhaust structure of any of the preceding items.

[0074] The present invention provides a rotor compressor exhaust structure. A self-controlled sliding valve structure is adopted, including an exhaust slider and a comparative pressure slider. The structure is arranged on the surface of the cylinder, and a resonance cavity is opened next to it. The exhaust gas of the compressor enters the spring slider through the flow channel on the slide. The entire slider structure adopts PEEK material, which can greatly absorb impact loads and noise. The synchronous upper flange structure will be greatly simplified, and only one exhaust hole is required, which greatly improves the processability; secondly, the compression stage is divided into two sections to ensure that there is no liquid refrigerant involved in the exhaust process, thereby avoiding liquid compression; finally, when the compressor is running at high frequency, the exhaust pressure is prevented from being greater than the spring force, resulting in excessive valve opening, unable to form a pressure difference, and resulting in a decrease in capacity. A comparative pressure slider structure is introduced. When the pressure in the compression chamber increases, the comparative slider moves toward the inside of the cylinder and connects to the exhaust slider to ensure the dynamic balance of pressure at both ends and reduce high-frequency capacity attenuation.

[0075] The self-control slide valve structure is made of PEEK (polyetheretherketone). PEEK material has good toughness and can absorb the impact load of exhaust. The contact stress is also smaller than that of metal valve plates, which greatly reduces exhaust noise. The slide valve adopts a self-control structure, which is divided into an exhaust slider and a comparative pressure slider. At the same time, a flow channel groove is opened on the slider. The rotor will only be turned on at the beginning of compression, and the exhaust process will not start until the pressure is greater than the spring set pressure. When running at high frequency, the exhaust pressure increases sharply. At this time, the exhaust chamber absorbs part of the exhaust noise. At the same time, the high pressure pushes the comparative pressure slider to move, and the exhaust port is closed in cooperation with the exhaust slider spring force, so as to keep the compressor in dynamic balance operation at the set optimal pressure and keep the high-frequency capacity without attenuation.

[0076] The present disclosure also provides an air conditioner, which includes the aforementioned compressor.

Any modifications, equivalent replacements and improvements made within the spirit and principles of the present disclosure shall be included in the protection scope of the present disclosure. The above are only preferred implementations of the present disclosure. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present disclosure, and these improvements and variations should also be regarded as the protection scope of the present disclosure.
