Description

Technical Field

[0001] This invention relates to the field of compressor technology, and in particular to a self-lubricating mechanism, a compressor, and an air conditioner. Background Technology

[0002] In the field of rotary compressors for air conditioning systems, the "ticking" noise that occurs under low-frequency operation is one of the key technical challenges restricting the product's quietness and user experience. Existing technical research indicates that this noise phenomenon mainly stems from insufficient lubrication between the vane and the cylinder vane slot. This causes the vane to fail to achieve stable and continuous contact with the outer circumference of the rotor rollers during radial movement. Specifically, when the compressor operates at low frequencies, the rotor rotation speed is low, and the radial thrust obtained by the vane under centrifugal force is weakened. At this time, the vane mainly relies on the preload provided by the return spring to maintain contact with the rollers. However, due to the high frictional resistance between the vane and the cylinder vane slot, and the reduced oil supply efficiency of the lubrication system under low-speed conditions, the vane... When the slide plate is squeezed by the roller during the compression stroke, if the spring force is insufficient to overcome the static friction between the slide plate and the slide plate groove, the slide plate will exhibit "lag" or "hysteresis" and will not be able to respond to the movement trajectory of the roller in time, causing the slide plate to briefly disengage from the roller. Subsequently, at the end of the compression stroke and during the pressure drop phase, the spring force gradually recovers and exceeds the dynamic friction between the slide plate and the groove wall. The slide plate rebounds rapidly under the drive of the spring and re-collides rigidly with the roller. This periodic "disengagement-re-contact" dynamic process has a high occurrence frequency under low-frequency operating conditions, and its impact energy is concentrated in the mid-low frequency range, forming a "ticking" noise that affects the overall performance of the machine. Summary of the Invention

[0003] The embodiments of the present invention provide a self-lubricating mechanism, a compressor, and an air conditioner, which solves the technical problem that the lubrication supply between the vane and the cylinder vane groove is delayed under low-frequency operation conditions, resulting in failure of dynamic contact of the vane and abnormal noise.

[0004] To address the aforementioned problems, according to one aspect of this application, an embodiment of the present invention provides a self-lubricating mechanism. The self-lubricating mechanism includes a slide body, and the slide body is internally provided with an oil supply assembly and a one-way control assembly. The one-way control assembly is disposed within the oil supply assembly, and the oil supply assembly has an oil outlet structure extending to the side wall of the slide body. The one-way control assembly can cooperate with the oil supply assembly to conduct under the pressure generated by the movement of the slide body, so that lubricating oil is supplied through the oil outlet structure to the space between the slide body and the cylinder slide groove.

[0005] In some embodiments, the oil supply assembly further includes an oil storage section and an oil guiding channel. The oil storage section is disposed at the tail end of the slide body, and the oil guiding channel is disposed inside the slide body. One end of the oil guiding channel is connected to the oil storage section, and the other end forms the oil outlet structure.

[0006] In some embodiments, the oil guide channel is arranged at an angle relative to the vane body, and the end of the oil guide channel near the oil storage part is higher than the end near the oil outlet structure.

[0007] In some embodiments, the oil guiding channel is a variable cross-section channel, and the diameter of the end of the oil guiding channel connected to the oil storage section is smaller than the diameter of the end connected to the oil outlet structure.

[0008] In some embodiments, the one-way control component includes a sphere disposed inside the oil guiding channel. The diameter of the sphere is larger than the diameter of the end of the oil guiding channel connected to the oil storage section and smaller than the diameter of the end of the oil guiding channel connected to the oil outlet structure.

[0009] In some embodiments, the ball can move along the length of the oil guide channel. When the ball moves to the end of the oil guide channel connected to the oil storage part, it seals with the inner wall of the oil guide channel. When the ball moves to the end of the oil guide channel connected to the oil outlet structure, a gap is formed between the ball and the inner wall of the oil guide channel to allow lubricating oil to flow.

[0010] In some embodiments, the oil outlet structure is a through hole penetrating the side wall of the slide body. The position of the oil outlet structure on the slide body is set such that when the slide body extends to its maximum stroke relative to the cylinder slide groove, the oil outlet structure is still located in the cylinder slide groove, so that the side wall of the cylinder slide groove can limit the ball to prevent the ball from leaving the oil guide channel.

[0011] In some embodiments, the oil reservoir is connected to the back of the slide body, and the lubricating oil on the back of the slide body can enter the oil reservoir.

[0012] In some embodiments, the oil supply assembly, the one-way control assembly, and the back of the slide body together form a circulating oil circuit, in which lubricating oil can circulate.

[0013] In some embodiments, the oil storage section is a cavity structure formed by a recess at the tail of the slide body, used for temporarily storing lubricating oil.

[0014] According to another aspect of this application, an embodiment of the present invention provides a compressor, the compressor including a cylinder, rollers and the aforementioned self-lubricating mechanism, wherein the vane body is slidably disposed in the vane groove of the cylinder, and the end of the vane body cooperates with the outer peripheral surface of the roller.

[0015] In some embodiments, when the slide body reciprocates within the slide groove, the one-way control component operates under the pressure inside the slide body to control the on / off state of the oil supply component.

[0016] According to another aspect of this application, an embodiment of the present invention provides an air conditioner that includes the compressor described above.

[0017] Compared with the prior art, the self-lubricating mechanism of the present invention has at least the following beneficial effects: The self-lubricating mechanism provided by the present invention includes a slide body, wherein an oil supply component and a one-way control component are provided inside the slide body. The one-way control component is disposed inside the oil supply component, and the oil supply component has an oil outlet structure extending to the side wall of the slide body. The one-way control component can cooperate with the oil supply component to conduct under the pressure generated by the movement of the slide body, so that lubricating oil is supplied to the space between the slide body and the cylinder slide groove through the oil outlet structure.

[0018] The self-lubricating mechanism in this invention effectively solves the problem through the coordinated operation of the vane body, the oil supply assembly, and the one-way control assembly. Even under low-frequency operating conditions, the vane body can generate stable internal pressure through its own reciprocating motion, eliminating reliance on centrifugal force to drive the oil supply. This allows the one-way control assembly to stably respond to pressure changes and coordinate with the oil supply assembly, fundamentally improving the problem of oil supply lag at low speeds. The oil supply assembly is integrated inside the vane body, with its oil outlet structure directly connected to the friction interface. This enables rapid and direct supply of lubricating oil between the vane body and the cylinder vane groove, significantly reducing frictional resistance and preventing vane slack due to insufficient lubrication. The one-way control assembly stably controls the oil flow direction within the oil supply assembly, preventing backflow and ensuring continuous and reliable lubrication. This allows the vane to maintain smooth movement even at low frequencies, stably adhering to the rollers and preventing "ticking" noises caused by slack, detachment, and re-collision, thereby improving the compressor's quietness and operational stability.

[0019] The compressor provided by this invention is designed based on the above-mentioned self-lubricating mechanism. Its beneficial effects are described in the same way as those of the self-lubricating mechanism, and will not be repeated here.

[0020] The air conditioner provided by this invention is designed based on the above-mentioned compressor, and its beneficial effects are the same as those of the compressor, which will not be repeated here.

In the following description, different "an embodiment" or "an embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0025] In the description of this invention, it should be clearly stated that the terms "first," "second," etc., in the specification, claims, and accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence; the terms "vertical," "lateral," "longitudinal," "front," "rear," "left," "right," "up," "down," "horizontal," etc., indicate orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, and are merely for the convenience of describing this invention, and do not mean that the device or element referred to must have a specific orientation or position, and therefore should not be construed as a limitation of this invention.

[0026] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0027] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0028] Example 1 This embodiment provides a self-lubricating mechanism, such as Figures 1-8 As shown, the self-lubricating mechanism includes a slide body 1. The slide body 1 is provided with an oil supply component 2 and a one-way control component 3. The one-way control component 3 is disposed inside the oil supply component 2. The oil supply component 2 has an oil outlet structure 21 extending to the side wall of the slide body 1. The one-way control component 3 can cooperate with the oil supply component 2 to conduct under the pressure generated by the movement of the slide body 1, so that lubricating oil is supplied to the space between the slide body 1 and the cylinder slide groove through the oil outlet structure 21.

[0029] The vane body 1, as the main structure of the self-lubricating mechanism, provides a stable installation space for the oil supply component 2 and the one-way control component 3, allowing them to be integrated internally. This also ensures that the vane body 1 can reciprocate normally within the cylinder vane slot. The oil supply component 2 is entirely housed inside the vane body 1, with its extended oil outlet structure 21 directly penetrating the side wall of the vane body 1 and aligning with the mating area between the vane body 1 and the cylinder vane slot. This allows the lubricating oil to directly act on the friction points, reducing delays caused by the delivery path. The one-way control component 3 is entirely housed within the oil supply component 2, forming a compact internal fit. This arrangement does not disrupt the oil circuit continuity of the oil supply component 2 while effectively controlling the flow of the lubricating oil. The vane body 1, relying on the pressure changes generated by its reciprocating motion, provides power for the action of the one-way control component 3. These three components are spatially interdependent and functionally supportive, together forming a complete lubrication execution structure.

[0030] When the vane body 1 reciprocates within the cylinder vane slot, its internal pressure changes regularly with the movement. This pressure change directly affects the one-way control component 3 located inside the oil supply assembly 2, causing it to perform a corresponding action. When the pressure reaches the conduction condition, the one-way control component 3 and the oil supply assembly 2 are connected. The lubricating oil inside the oil supply assembly 2 flows along the internal channel under pressure and is continuously delivered to the contact surface between the vane body 1 and the cylinder vane slot through the oil outlet structure 21. When the pressure direction changes, the one-way control component 3 immediately closes, blocking the reverse flow of lubricating oil and ensuring that the oil supply assembly 2 always maintains a stable oil reserve. The entire process is synchronized with the movement of the vane body 1, requiring no additional driving components, thus achieving real-time matching between lubrication supply and vane movement.

[0031] To address the problems of insufficient lubrication and delayed oil supply in compressors during low-frequency operation, which lead to vane slack and abnormal noise, the self-lubricating mechanism in this embodiment effectively solves these problems through the coordinated operation of the vane body 1, the oil supply assembly 2, and the one-way control assembly 3. Even under low-frequency operating conditions, the vane body 1 can still generate stable internal pressure through its own reciprocating motion, eliminating the need for centrifugal force to drive oil supply. This allows the one-way control assembly 3 to stably respond to pressure changes and cooperate with the oil supply assembly 2, fundamentally improving the problem of delayed oil supply at low speeds. The oil supply assembly 2 is integrated inside the vane body 1, and its oil outlet structure 21 directly connects to the friction interface, enabling rapid and direct supply of lubricating oil between the vane body 1 and the cylinder vane groove. This significantly reduces frictional resistance and prevents vane slack due to insufficient lubrication. The one-way control component 3 stably controls the flow of oil inside the oil supply component 2, prevents backflow of lubricating oil, ensures continuous and reliable lubrication process, and enables the vane to maintain smooth movement even when running at low frequency, stably adhering to the roller, avoiding "clicking" noise caused by stagnation, separation and re-collision, thereby improving the compressor's quietness and operational stability.

[0032] In a specific embodiment, the oil supply assembly 2 further includes an oil storage section 22 and an oil guiding channel 23. The oil storage section 22 is disposed at the tail end of the slide body 1, and the oil guiding channel 23 is disposed inside the slide body 1. One end of the oil guiding channel 23 is connected to the oil storage section 22, and the other end forms the oil outlet structure 21.

[0033] The oil reservoir 22 is located at the tail of the vane body 1 and can stably hold lubricating oil, providing a continuous oil source for the entire lubrication process. The oil guide channel 23 is arranged inside the vane body 1, with one end directly connected to the oil reservoir 22, which can smoothly introduce the lubricating oil stored in the oil reservoir 22. The other end extends to form an oil outlet structure 21, which allows the lubricating oil to be stably transported along a preset path to the mating area between the vane body 1 and the cylinder vane groove. The oil reservoir 22 and the oil guide channel 23 achieve orderly oil transfer through their interconnection. The oil reservoir 22 is responsible for collecting and retaining lubricating oil to prevent oil loss, while the oil guide channel 23 undertakes the function of oil transportation, accurately guiding the lubricating oil from the tail of the vane body 1 to the oil outlet position on the side wall. The two work together to form a complete oil supply path, allowing the lubricating oil to be stably and continuously supplied to the friction parts that need lubrication, reducing the loss and delay in the oil transportation process, and ensuring that the vane body 1 can always obtain reliable lubrication support during the movement.

[0034] In addition, the self-lubricating mechanism in this embodiment also has an adaptive positive feedback control mechanism, giving the lubrication system significant adaptability. As the compressor load increases, its rotation frequency increases accordingly, leading to more reciprocating cycles of the vane body 1. The driving force on the vane body 1 increases accordingly, and the displacement amplitude and motion frequency increase synchronously, resulting in an increase in the pressure gradient at the inlet of the oil guide channel 23. The increased pressure gradient can push more refrigerant oil (lubricating oil) into the oil guide channel 23. This feature achieves a positive response of "the greater the demand, the more oil is supplied," allowing the lubrication supply to automatically match the heat load, wear trend, and sealing requirements of the actual friction pair (between the vane body 1 and the cylinder vane groove). This avoids oil waste caused by excessive lubrication and eliminates problems such as component wear and abnormal noise caused by insufficient lubrication, further improving the adaptability and reliability of the self-lubricating mechanism.

[0035] In a specific embodiment, the oil guiding channel 23 is arranged at an angle relative to the slide body 1, and the end of the oil guiding channel 23 near the oil storage part 22 is higher than the end near the oil outlet structure 21.

[0036] The oil guide channel 23 is not arranged horizontally along the axial or radial direction of the vane body 1, but is embedded in the vane body 1 in an inclined state. The end of the channel near the oil storage part 22 is significantly higher than the end near the oil outlet structure 21. This inclined arrangement is adapted to the positional distribution of the oil storage part 22 and the oil outlet structure 21. The oil storage part 22 is located at the tail of the vane body 1, and the oil outlet structure 21 runs through the side wall of the vane body 1. The inclined oil guide channel 23 can connect the two, forming a smooth oil flow path. Thanks to this inclined design, the lubricating oil in the oil reservoir 22 can naturally flow towards the lower oil outlet structure 21 under its own gravity. Without additional power assistance, it can work with the pressure generated by the movement of the vane body 1 to further accelerate the delivery speed of the lubricating oil, reduce the retention of lubricating oil in the oil guide channel 23, and ensure that the lubricating oil can be delivered to the friction interface between the vane body 1 and the cylinder vane groove in a timely manner through the oil outlet structure 21. This effectively alleviates the problem of lubrication supply lag, allowing the vane body 1 to always obtain sufficient lubricating oil during the movement, ensuring the continuity and timeliness of lubrication.

[0037] In a specific embodiment, the oil guiding channel 23 is a variable cross-section channel, and the diameter of the end of the oil guiding channel 23 connected to the oil storage part 22 is smaller than the diameter of the end connected to the oil outlet structure 21.

[0038] The oil guide channel 23 adopts a variable cross-section structure. The diameter of the entire channel gradually increases from the end connected to the oil reservoir 22 to the end forming the oil outlet structure 21. The diameter is smaller at the end closer to the oil reservoir 22 and larger at the end closer to the oil outlet structure 21. This size distribution can match the oil outlet state of the oil reservoir 22 and the oil supply requirements of the oil outlet structure 21. The smaller inlet diameter allows lubricating oil to enter the oil guide channel 23 stably from the oil reservoir 22, avoiding turbulence or backflow at the inlet and ensuring the stability of the oil flow. The larger outlet diameter can expand the flow range of the lubricating oil, allowing the oil to cover the mating area between the vane body 1 and the cylinder vane groove more evenly, reducing the situation of insufficient local lubrication. At the same time, the gradually smooth inner wall of the channel can reduce the frictional resistance encountered by the lubricating oil during the flow process. Combined with the inclined arrangement of the oil guide channel 23, the oil can be smoothly transported forward along the channel, further improving the smoothness and uniformity of lubrication supply and ensuring timely lubrication.

[0039] In a specific embodiment, the one-way control component 3 includes a sphere disposed inside the oil guiding channel 23. The diameter of the sphere is larger than the diameter of the end of the oil guiding channel 23 connected to the oil storage part 22, and smaller than the diameter of the end of the oil guiding channel 23 connected to the oil outlet structure 21.

[0040] The ball is directly arranged in the internal space of the oil guide channel 23. Its diameter is reasonably set to be larger than the diameter of the end of the oil guide channel 23 connected to the oil storage part 22, and smaller than the diameter of the end of the oil guide channel 23 connected to the oil outlet structure 21. This size matching allows the ball to maintain a reasonable range of motion inside the oil guide channel 23. It can achieve stable fit and sealing at the end near the oil storage part 22, and will not be restricted by the channel diameter when moving towards the oil outlet structure 21. The size difference between the two ends of the ball and the oil guide channel 23 allows it to freely adjust its position according to the oil flow and pressure changes in the channel. While realizing the oil circuit on / off control, it is always confined to the oil guide channel 23 to work normally, ensuring the stability and reliability of the entire unidirectional control process, and also allowing the supply and blocking of lubricating oil to accurately respond to the movement state of the sliding body 1.

[0041] In a specific embodiment, the ball can move along the length of the oil guiding channel 23. When the ball moves to the end of the oil guiding channel 23 connected to the oil storage part 22, it seals with the inner wall of the oil guiding channel 23. When the ball moves to the end of the oil guiding channel 23 connected to the oil outlet structure 21, a gap is formed between the ball and the inner wall of the oil guiding channel 23 to allow lubricating oil to flow.

[0042] The ball can move smoothly along the length of the oil guide channel 23. Its movement will naturally adjust according to the pressure changes inside the slide body 1 and the flow trend of the lubricating oil. When the end of the ball that is connected to the oil guide channel 23 and the oil storage part 22 approaches, it will completely fit with the inner wall of the channel at that position to form a reliable sealing fit. At this time, the lubricating oil inside the oil storage part 22 cannot continue to enter the oil guide channel 23, and the oil circuit is in a closed state, which can effectively prevent the lubricating oil from flowing back to the oil storage part 22 and ensure that the oil will not be lost ineffectively. When the end of the ball that is connected to the oil outlet structure 21 of the oil guide channel 23 moves, due to the change of the channel diameter, a continuous and stable flow gap will naturally be formed between the ball and the inner wall of the channel. The lubricating oil flowing out of the oil storage part 22 can smoothly pass through the oil guide channel 23 along this gap and be continuously delivered to the oil outlet structure 21. The switching between the two states completely follows the actual operating needs of the slide body 1, making the supply of lubricating oil more precise.

[0043] In a specific embodiment, the oil outlet structure 21 is a through hole penetrating the side wall of the slide body 1. The position of the oil outlet structure 21 on the slide body 1 is set such that when the slide body 1 extends to the maximum stroke relative to the cylinder slide groove, the oil outlet structure 21 is still located in the cylinder slide groove, so that the side wall of the cylinder slide groove can limit the ball to prevent the ball from leaving the oil guide channel 23.

[0044] The oil outlet structure 21 adopts a through-hole design that penetrates the side wall of the vane body 1. The inner diameter of the through-hole is matched with the diameter of the oil guide channel 23 near the oil outlet end, allowing the lubricating oil delivered in the oil guide channel 23 to pass smoothly and flow precisely to the friction contact surface between the vane body 1 and the cylinder vane groove, achieving direct and efficient lubrication replenishment and avoiding lubricating oil retention or leakage during the outgoing process. The position of the oil outlet structure 21 on the vane body 1 has been rigorously calculated and set, fully considering the maximum extension stroke of the vane body 1 in the cylinder vane groove, ensuring that even if the vane body 1 extends outward to its limit along the cylinder vane groove, the oil outlet structure 21 will not exceed the range of the cylinder vane groove and will always be surrounded and covered by the side wall of the cylinder vane groove. This reasonable arrangement allows the sidewall of the cylinder vane groove to form a natural limiting barrier on the outside of the oil outlet structure 21. When the ball moves within the oil guide channel 23 to the end connected to the oil outlet structure 21 due to pressure changes and oil flow, the sidewall of the cylinder vane groove effectively blocks the ball, restricting its further outward movement. This reliably prevents the ball from exiting the oil guide channel 23 through the oil outlet structure 21, ensuring that the ball always moves within the oil guide channel 23. This guarantees that the one-way control component 3 can normally control the oil circuit, while also not obstructing the smooth flow of lubricating oil from the oil outlet structure 21, thus balancing the reliability of the limiting barrier with the continuity of lubrication.

[0045] In a specific embodiment, the oil storage section 22 is connected to the back of the slide body 1, and the lubricating oil on the back of the slide body 1 can enter the oil storage section 22.

[0046] The oil reservoir 22 is not a closed cavity structure at the tail of the vane body 1. Its side wall has a connecting channel that communicates with the back of the vane body 1. The diameter of the connecting channel matches the cavity size of the oil reservoir 22, ensuring smooth oil flow. This connecting design provides a continuous path for replenishing the lubricating oil on the back of the vane body 1. When the vane body 1 reciprocates within the cylinder vane slot, its back is always immersed in the compressor's lubricating oil environment. As the vane body 1 extends and retracts, the space between its back and the cylinder vane slot changes periodically, creating a pressure difference. Under the combined effect of this pressure difference and its own gravity, the lubricating oil on the back flows naturally into the oil reservoir 22 through the connecting channel, completing the oil replenishment. This design transforms the oil reservoir 22 from an isolated storage space into a space capable of real-time oil exchange with the external lubrication environment. When the lubricating oil in the oil reservoir 22 is transported out through the oil guide channel 23, the oil on the back of the vane body 1 will promptly fill the gap, ensuring that the oil reservoir 22 always has sufficient lubricating oil reserves. This provides a continuous source of oil for subsequent lubrication, allowing the entire self-lubricating mechanism to maintain a stable oil supply capacity during long-term operation and preventing lubrication interruption due to oil depletion.

[0047] In a specific embodiment, the oil supply component 2, the one-way control component 3, and the back of the slide body 1 together form a circulating oil circuit, in which lubricating oil can circulate.

[0048] The oil supply component 2, the one-way control component 3, and the back of the slide body 1 are interconnected to form a closed circulation oil circuit. The lubricating oil can continuously flow along a fixed path in this oil circuit. The lubricating oil on the back of the slide body 1 can enter the oil storage section 22 inside the oil supply component 2 through the connecting structure, and then be transported to the mating area between the slide body 1 and the cylinder slide groove through the oil guide channel 23 and the oil outlet structure 21. After lubrication, the lubricating oil will flow back to the back of the slide body 1 and re-enter the oil storage section 22 to participate in the next round of lubrication supply. The whole process can achieve the reuse of lubricating oil without external intervention, which not only ensures that the slide body 1 can obtain continuous and stable lubrication during the movement, but also reduces the ineffective consumption of lubricating oil, so that the entire self-lubricating mechanism can maintain smooth oil circuit and balanced oil supply during operation.

[0049] In a specific embodiment, the oil storage section 22 is a cavity structure formed by the recess at the tail of the slide body 1, which is used to temporarily store lubricating oil.

[0050] The oil reservoir 22 is not an additional component separate from the slide body 1, but rather a cavity structure formed directly at the tail of the slide body 1 through recessed machining. This integrated design allows the oil reservoir 22 to be tightly connected to the slide body 1 without additional assembly processes, saving installation space and ensuring the structural stability of the oil reservoir 22, preventing it from loosening or falling off during the reciprocating motion of the slide body 1. The cavity size of the oil reservoir 22 is rationally designed to hold a sufficient amount of lubricating oil. Its core function is to temporarily store the lubricating oil flowing in from the back of the slide body 1. When the slide body 1 moves and generates pressure, requiring the supply of lubricating oil to the friction interface, the oil stored in the oil reservoir 22 can promptly enter the oil guide channel 23, ensuring timely lubrication supply. When the lubrication demand decreases and the oil flows back, the oil reservoir 22 can temporarily hold excess lubricating oil, preventing oil waste and also reserving sufficient oil for subsequent lubrication cycles.

[0051] The lubrication process of the self-lubricating mechanism provided in Example 1 is as follows: When the vane body 1 reciprocates within the cylinder vane groove, the lubricating oil on its back continuously enters the oil reservoir 22 formed by the tail recess, providing a stable oil source for the entire lubrication process. Of course, additional lubricating oil can be added if necessary. The lubricating oil inside the oil reservoir 22 flows towards the oil outlet structure 21 along the inclined oil guide channel 23 under the combined action of its own gravity and the pressure of the vane body 1's movement. The oil guide channel 23 adopts a variable cross-section design with a smaller diameter near the oil reservoir 22 and a larger diameter near the oil outlet structure 21, allowing for smoother and more uniform oil flow and reducing flow resistance. The ball located inside the oil guide channel 23 moves flexibly along the length of the channel due to the periodic pressure changes generated by the movement of the vane body 1. When the ball moves to the end of the oil guide channel 23 connected to the oil reservoir 22, it will tightly fit against the inner wall of the channel to form a sealed fit. Figure 3 Point A and Figure 5 This effectively prevents lubricating oil from flowing back into the oil reservoir 22; when the ball moves to the end of the oil guide channel 23 connected to the oil outlet structure 21, it will form a uniform flow gap with the inner wall of the channel, such as... Figure 4 Point B and Figure 6 After passing through the gap, the oil is precisely delivered to the mating interface between the slide body 1 and the cylinder slide groove via the oil outlet structure 21 that penetrates the side wall of the slide body 1, achieving precise lubrication of the friction surface. The position of the oil outlet structure 21 ensures that the slide body 1 remains inside the cylinder slide groove even when extended to its maximum stroke. The side wall of the cylinder slide groove reliably limits the ball, preventing it from dislodging from the oil guide channel 23 and ensuring the normal operation of the one-way control component 3. After lubrication, the lubricating oil will flow back to the back of the slide body 1 under the reciprocating motion of the slide body 1, and flow back into the oil reservoir 22 to participate in the next cycle. The entire process relies on the closed-loop oil circuit formed by the oil supply component 2, the one-way control component 3, and the back of the slide body 1 to continuously ensure that the slide body 1 receives timely and stable lubrication throughout the entire movement, avoiding lubrication interruption.

[0052] Example 2 This embodiment provides a compressor, which includes a cylinder, rollers, and the self-lubricating mechanism described in Embodiment 1. The vane body 1 is slidably disposed in the vane groove 4 of the cylinder, and the end of the vane body 1 cooperates with the outer peripheral surface of the roller.

[0053] The compressor provided in this embodiment uses a cylinder and rollers as core moving parts, and integrates the aforementioned self-lubricating mechanism. The overall structure is compact and the operating logic is clear. The cylinder has a matching vane groove 4 machined inside. The vane body 1 is slidably mounted inside the vane groove 4 of the cylinder, and can make stable reciprocating motion in accordance with the operating rhythm of the compressor. The end of the vane body 1 maintains continuous contact with the outer peripheral surface of the roller. During the rotation of the roller, it pushes the vane body 1 to make extension and retraction movements in the vane groove 4. The vane body 1 completes the volume change of the compressor working chamber by its own sliding contact. The self-lubricating mechanism plays a continuous role in the entire movement of the vane body 1, directly providing stable lubrication to the mating surface between the vane body 1 and the cylinder vane groove 4, reducing the frictional resistance when the vane body 1 slides, so that the vane body 1 can respond more smoothly to the rotation trajectory of the roller, maintain stable contact with the outer peripheral surface of the roller, and thus improve the overall smoothness and quietness of the compressor operation.

[0054] In a specific embodiment, when the slide body 1 reciprocates within the slide groove 4, the one-way control component 3 operates under the pressure inside the slide body 1 to control the on / off state of the oil supply component 2.

[0055] During compressor operation, the vane body 1 reciprocates continuously within the vane groove 4 of the cylinder, following the rotation of the rollers. This movement causes periodic pressure changes within the vane body 1. The internal pressure directly acts on the one-way control component 3 located inside the oil supply assembly 2, causing the one-way control component 3 to respond accordingly. When the vane body 1 retracts inward, the internal pressure increases, and the one-way control component 3 changes position under pressure, keeping the oil passage within the oil supply assembly 2 open. Lubricating oil can then pass smoothly and be delivered to the friction interface. When the vane body 1 extends outward, the internal pressure decreases or reverse pressure occurs, and the one-way control component 3 resets and cuts off the oil passage to prevent backflow of lubricating oil. The entire on / off control process relies entirely on the pressure generated by the movement of the vane body 1 itself, without the need for an additional drive structure. It can precisely adjust the oil supply state according to the actual operating conditions of the compressor, keeping the lubrication supply synchronized with the movement rhythm of the vane body 1.

[0056] Example 3 This embodiment provides an air conditioner, which includes the compressor described in Embodiment 2.

[0057] The air conditioner provided in this embodiment uses the compressor described in Embodiment 2 as its core refrigeration power component. This compressor integrates the self-lubricating mechanism from Embodiment 1, providing reliable support for the stable and efficient operation of the air conditioner. During operation, the compressor, as the core component of the refrigeration cycle, works in concert with its internal cylinder, rollers, and vane body 1. The vane body 1 is slidably mounted in the vane groove 4 of the cylinder, with its end tightly fitted to the outer circumferential surface of the roller. It performs a smooth reciprocating extension and retraction motion following the rotation of the roller, thereby completing the compression and delivery of the refrigerant and providing continuous power for the air conditioner to achieve its cooling or heating functions. The self-lubricating mechanism integrated into the compressor continuously functions throughout the reciprocating motion of the vane body 1, effectively reducing the frictional resistance between the vane body 1 and the cylinder vane groove 4. This fundamentally avoids the "ticking" noise caused by insufficient lubrication during low-frequency compressor operation, ensuring the smoothness and quietness of compressor operation. The stable and efficient operation of the compressor directly determines the cooling and heating efficiency, energy consumption level, and overall performance of the air conditioner. Air conditioners equipped with this compressor can not only achieve fast and stable temperature regulation to meet user needs, but also improve the user experience with the low-noise operation characteristics of the compressor. At the same time, it reduces mechanical wear inside the compressor, extends the compressor's service life, and thus extends the overall service life of the air conditioner, reducing user operating costs.
