Description
Technical Field
[0001] The present invention belongs to the technical field of air conditioners, and in particular relates to a compressor and an air conditioner having the compressor. Background Art
[0002] Household and commercial air conditioners are widely used. As people's requirements for efficient refrigeration are increasing, the oil circulation rate requirements for scroll compressors in air conditioning systems are becoming more stringent. Existing methods for reducing the oil circulation rate include increasing the outer diameter of the balance block, installing air guides, or laying oil return pipes.
[0003] The circumferential motion is an important aid in separating the high-temperature and high-pressure lubricating oil and refrigerant mixture in the compressor. The change in flow rate can separate the two mixed fluids. The refrigerant compressed by the pump body assembly is a mixed fluid. The pump body assembly discharges the refrigerant into the motor chamber. The circumferential motion will throw the mixed fluid onto the wall. The lubricating oil will separate on the inner wall of the shell, hang on the inner wall of the shell to form an oil film, and slowly flow to the oil pool at the bottom of the compressor. When the compressor is running at high frequency, the rotation speed of the crankshaft increases, and the flow rate of the circumferential motion increases, which can better separate the lubricating oil and the refrigerant. Therefore, under high-frequency conditions, the oil circulation rate of the compressor is relatively low. At this time, if less refrigerant is discharged into the motor chamber, that is, the refrigerant outlet from the pump body assembly into the motor chamber is small, and the pressure at the outlet is high, which further accelerates the flow rate and increases the power consumption of the compressor. As a result, most methods for reducing the oil circulation rate of the compressor will increase the power consumption of the compressor under high-frequency conditions. Under low-frequency conditions, the compressor power consumption is low, but the oil circulation rate is high. Summary of the invention

DETAILED DESCRIPTION
[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0035] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.
[0036] For ease of description, spatially relative terms such as "on", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature with other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the figure is inverted, the device described as "above other devices or structures" or "on top of other devices or structures" will be positioned as "below" or "below other devices or structures" afterwards.
[0037] See also Figures 1 to 6 As shown, according to an embodiment of the present invention, a compressor is provided, including a pump body assembly 1 and a guide structure 2; the pump body assembly 1 has an exhaust port 101, and the guide structure 2 is arranged on the exhaust path of the exhaust port 101; the guide structure 2 includes a guide shell 3 and an air baffle plate 4, the guide shell 3 has an air inlet 301 and an air outlet 302 that are interconnected, and the air inlet 301 is connected to the exhaust port 101, the first end 41 of the air baffle plate 4 is movably connected to the guide shell 3, and the second end 42 of the air baffle plate 4 is movably arranged relative to the air outlet 302, so that the air baffle plate 4 blocks part of the air outlet 302 or is away from the air outlet 302.
[0038] Specifically, when the compressor is running, the crankshaft 102 of the pump body assembly 1 rotates, and the crankshaft 102 drives the gas to perform circumferential motion. The circumferential motion is an important aid for separating the high-temperature and high-pressure lubricating oil and refrigerant mixture in the compressor. The change in circumferential flow velocity can separate the two mixed fluids. The circumferential motion will cause the mixed fluid to hang on the wall of the compressor components, causing the velocity to drop sharply to 0. The lubricating oil will separate and hang on the wall of the components to form an oil film, and slowly flow to the oil pool at the bottom of the compressor, thereby reducing the lubricating oil flowing out of the compressor exhaust pipe, thereby achieving the purpose of reducing the oil circulation rate. The oil circulation rate here refers to the amount of oil leaked from the compressor to the air-conditioning system. The lubricating oil cannot be completely discharged from the compressor, but the relative discharge amount of the lubricating oil can be adjusted.
[0039] Specifically, after the gas flowing out of the exhaust port 101 flows into the guide structure 2 from the air inlet 301, the gas flows out from the air outlet 302 for oil-gas separation. The area of the air outlet 302 determines the outflow amount and the outflow speed of the gas. The operating conditions of the compressor are different, and the rotation speed of the crankshaft 102 of the pump body assembly 1 is also different. For the outflow amount and the outflow speed of the gas, when the compressor operates at a low frequency, the rotation speed of the crankshaft 102 is slow, and the bypass flow velocity is also small. At this time, the oil circulation rate is high, that is, the amount of oil leaked from the compressor to the air-conditioning system. Under this condition, the air baffle 4 blocks part of the air outlet 302, and the gas passing area of the air outlet 302 is reduced. When the gas flows out from here, the flow velocity of the gas increases, thereby increasing the bypass flow velocity, accelerating the oil-gas separation, and thereby reducing the oil circulation rate; when the compressor operates at a high frequency, the oil circulation rate is reduced. During high-frequency working conditions, the rotation speed of the crankshaft 102 is relatively fast and the flow velocity is relatively large, so that the lubricating oil and refrigerant mixture can be fully separated from the oil and gas, that is, there is no need for the gas to have a high outflow velocity at the air outlet 302. However, when the compressor operates under high-frequency working conditions, although the oil circulation rate is low, the power consumption of the compressor is relatively high. The air baffle plate 4 is adjusted to no longer block the air outlet 302, but to be away from the air outlet 302, so that the air outlet 302 is fully opened. At this time, the amount of gas flowing out of the air outlet 302 is relatively large, and the gas outflow velocity is relatively low, thereby reducing the exhaust resistance of the gas and reducing the power consumption of the compressor.
[0040] In this embodiment, compared with the conventional gas flowing out from the pump body assembly 1 directly participating in the circumferential flow motion, in this embodiment, a guide structure 2 is provided on the discharge path of the exhaust port 101. The guide structure 2 can adjust the amount of gas participating in the circumferential flow motion and the gas flow rate, and the guide structure 2 provides a clear flow path for the gas flowing out from the exhaust port 101. Through the setting of the guide shell 3, the gas is guided from the air inlet 301 into the inside of the guide structure 2, and then flows out from the air outlet 302. This orderly guiding effect can avoid disorderly diffusion of the gas inside the compressor. The air baffle plate 4 can adjust the outflow speed of the gas by blocking or keeping away from the air outlet 302. The adjustability of the air baffle plate 4 enables it to be adaptively adjusted according to the different operating conditions of the compressor. This flexibility enables the compressor to maintain high working efficiency and performance under various operating conditions, thereby improving the applicability and reliability of the compressor. By adjusting the area of the air outlet 302 according to the operating conditions of the compressor, the flow state and speed of the gas can be optimized, thereby improving the overall efficiency of the system, and enabling the compressor to better adapt to different load changes. By adjusting the area of the air outlet 302, the problem of the existing method of reducing the oil circulation rate of the compressor increasing the power consumption of the compressor under high-frequency conditions and the low power consumption of the compressor but the high oil circulation rate under low-frequency conditions is overcome.
[0041] It is worth noting that, in this embodiment, the flow rate and flow velocity of the gas participating in the circumferential flow movement can be adjusted by setting the flow guide structure 2, and the movable mode of the air blocking plate 4 can be reasonably set to move the air blocking plate 4 by the change of the air flow; the relevant structure can also be set to automatically move the air blocking plate 4 according to the operation change of the compressor by driving; and a rocker connecting rod structure can also be set, and the air flow acts on the rocker connecting rod structure, and the rocker connecting rod structure pushes the air blocking plate 4 to move. In this embodiment, the specific moving mode of the air blocking plate 4 can be flexibly selected to ensure that the air blocking plate 4 can move when the working condition of the compressor changes.
[0042] See also Figures 3 to 8 As shown, the guide structure 2 also includes a swing plate 5, one end of which is movably connected to the guide housing 3, and the other end of the swing plate 5 is movably connected to the first end 41 of the air-blocking plate 4. The swing plate 5 has a first end face 51 and a second end face 52 relative to each other, and the second end face 52 faces the air-blocking plate 4. After the air-blocking plate 4 is hinged to the swing plate 5, the air-blocking plate 4 is equivalent to being stacked on one side of the second end face 52, the first end face 51 is used to withstand the first pressure, and the second end face 52 is used to withstand the second pressure, and a pressure difference is formed between the first end face 51 and the second end face 52, and the swinging of the swing plate 5 drives the air-blocking plate 4 to move. Specifically, the present embodiment adopts the method of setting a swing plate 5 to push the air blocking plate 4 to move. When the compressor operates at a low frequency, the first end face 51 is subjected to a relatively large pressure. Although the second end face 52 also has a certain pressure, the first pressure is greater than the second pressure. There is a pressure difference between the first end face 51 and the second end face 52. The side with a larger pressure pushes the swing plate 5 to swing toward the air blocking plate 4. At this time, the swing plate 5 pushes the first end 41 of the air blocking plate 4 to move, and then pushes the second end 42 of the air blocking plate 4 to move toward the air outlet 302, thereby partially blocking the air outlet 303. 02, increase the flow rate of gas at the air outlet 302; when the compressor operates at a high frequency, the pressure on the first end face 51 is reduced, and the second pressure is greater than the first pressure. There is still a pressure difference between the first end face 51 and the second end face 52. The side with greater pressure pushes the swing plate 5 to swing away from the air blocking plate 4. At this time, the swing plate 5 pulls the first end 41 of the air blocking plate 4 to move in the opposite direction, and then pulls the second end 42 of the air blocking plate 4 away from the air outlet 302. The air outlet 302 is fully opened, reducing the flow rate of the gas at the air outlet 302 and reducing the exhaust resistance.
[0043] As a specific implementation, the two ends of the swing plate 5 are respectively connected to the guide housing 3 and the air blocking plate 4. In this embodiment, the best mode is that one end of the swing plate 5 is hinged to the guide housing 3, and the other end of the swing plate 5 is hinged to the first end 41 of the air blocking plate 4, that is, the rotation connection between the components is realized. In other embodiments, it can also be a flexible connection, for example, one end of the swing plate 5 is connected to the guide housing 3 through an elastic sheet, and the other end of the swing plate 5 is connected to the air blocking plate 4 through a spring. In this way, when the airflow pushes the swing plate 5, the elastic sheet deforms and the swing plate 5 swings a certain angle, the swing plate 5 drives the spring to move, the spring pushes the air blocking plate 4 to move and block part of the air outlet 302, and under the action of gravity, the spring changes from a compressed state to an extended state; when there is no pressure difference between the first end face 51 and the second end face 52, the swing plate 5 is reset, pulling the spring to reset, the spring pulls the first end 41 of the air blocking plate 4 to move in the opposite direction, the spring is compressed, and the air outlet 302 is opened.
[0044] In this embodiment, the swing of the swing plate 5 is used to push or pull the air blocking plate 4 to move, thereby automatically adjusting the area of the air outlet 302. Under low-frequency conditions, blocking part of the air outlet 302 can increase the flow rate of the gas at the air outlet 302, which is conducive to accelerating the oil-gas separation and reducing the oil circulation rate; while under high-frequency conditions, fully opening the air outlet 302 can reduce the flow rate of the gas, reduce the exhaust resistance, and reduce the power consumption of the compressor. By optimizing the gas flow state, the working efficiency and performance of the compressor can be improved. The swing of the swing plate 5 is achieved based on the pressure difference between the first end face 51 and the second end face 52. This pressure difference-based adjustment method can accurately reflect the gas pressure changes inside the compressor, thereby making the system adjustment more stable and reliable, reducing the performance fluctuations and failure risks caused by improper adjustment, and adopting a structure combined with the swing plate 5 and the air blocking plate 4, the area of the air outlet 302 can be automatically adjusted without adding additional complex control devices or sensors, simplifying the overall structure of the system, and reducing the manufacturing cost and maintenance difficulty of the system.
[0045] It is worth noting that the first pressure applied to the first end face 51 in this embodiment is determined by the setting position of the swing plate 5. Gas will flow into the air inlet 301 of this embodiment. By adjusting the setting position of the swing plate 5, the first end face 51 is used to withstand the pressure applied by the gas in the air inlet 301, or the first end face 51 is set toward the pump body assembly 1, and the circumferential flow motion generated by the rotation of the crankshaft 102 can flow through the first end face 51, thereby applying the first pressure to the first end face 51. Similarly, the second pressure borne by the second end face 52 can also be achieved in a variety of ways, such as by setting a structure to guide the airflow to the second end face 52, or there is no airflow flowing through the second end face 52, but a telescopic member or elastic member 7 can be set on the second end face 52, and the telescopic member or elastic member 7 can apply the second pressure to the second end face 52. In the above manner, different pressures can be applied to the first end face 51 and the second end face 52 respectively, so as to form a pressure difference between the two end faces, so that the swing plate 5 can swing.
[0046] See also Figures 3 to 8 As shown, the side wall of the guide shell 3 is provided with a mounting groove 303, the swing plate 5 is installed in the mounting groove 303, the air outlet 302 and the mounting groove 303 are located on the same side of the guide shell 3, the first end face 51 faces the pump body assembly 1, and the second end face 52 faces the bottom wall of the mounting groove 303; the circumferential flow generated by the rotation of the pump body assembly 1 applies a first pressure to the first end face 51, and when the first pressure is greater than the second pressure, the air blocking plate 4 blocks part of the air outlet 302; when the first pressure is less than the second pressure, the air blocking plate 4 is away from the air outlet 302.
[0047] Specifically, after the swing plate 5 is installed in the installation groove 303, one end of the swing plate 5 is hinged to the guide shell 3, and the other end extends into the groove. The swing plate 5 is installed in the installation groove 303 as a whole. The swing plate 5 is a plate structure, and the first end face 51 faces the pump body assembly 1, and the second end face 52 faces the installation groove 303. When the crankshaft 102 of the pump body assembly 1 rotates, the flow motion will flow circumferentially along the end face of the guide shell 3, and the airflow generated by the flow motion will also flow through the swing plate 5. The circumferential flow generated by the rotation of the crankshaft 102 applies a first pressure to the first end face 51. Due to different operating conditions of the compressor, the flow velocity is different, and the applied first pressure is also different. When the compressor is operating at a low frequency, the flow velocity is small, and the corresponding first end face 51 is subjected to a large pressure. At this time, the first pressure is greater than the second pressure, and the swing plate 5 swings toward the bottom wall of the mounting groove 303. At this time, the swing plate 5 pushes the first end 41 of the air blocking plate 4 to move, and then pushes the second end 42 of the air blocking plate 4 to move toward the air outlet 302, thereby blocking part of the air outlet 302 and increasing the flow velocity of the gas at the air outlet 302. When the compressor is operating at a high frequency, the flow velocity is large, and the corresponding first end face 51 is subjected to a small pressure. At this time, the first pressure is less than the second pressure, and the swing plate 5 swings toward the side away from the bottom wall of the mounting groove 303. At this time, the swing plate 5 pulls the first end 41 of the air blocking plate 4 to move, and then pulls the second end 42 of the air blocking plate 4 away from the air outlet 302, thereby opening the air outlet 302 and reducing the flow velocity of the gas at the air outlet 302.
[0048] In this embodiment, the position of the air blocking plate 4 is automatically adjusted by the swing of the swing plate 5, thereby changing the area of the gas outlet 302. The swing of the swing plate 5 is realized according to the relative size between the pressure applied to the first end face 51 and the pressure of the second end face 52 by the circumferential flow generated by the rotation of the pump body assembly 1. This setting enables the system to automatically adjust according to the actual operating state of the compressor (low-frequency or high-frequency working condition) without human intervention, thereby improving the intelligence and response speed of the system. By optimizing the gas flow state, the working efficiency and performance of the compressor can be improved. The swing of the swing plate 5 is realized based on the circumferential flow pressure difference generated by the pump body assembly 1. This pressure difference-based adjustment method can accurately reflect the gas pressure change inside the compressor, thereby making the system adjustment more stable and reliable, and reducing the performance fluctuation and failure risk caused by improper adjustment. Moreover, by this method, the swing plate 5 and the air blocking plate 4 can be automatically adjusted according to the operating conditions of the compressor in real time. The swing of the swing plate 5 and the movement of the air blocking plate 4 can quickly respond to the changes in the compressor working conditions. This rapid response capability helps to timely adjust the area of the gas outlet 302 under different working conditions and optimize the gas flow state.
[0049] As a specific embodiment, in the axial direction of the guide shell 3, specifically on the side wall of the guide shell 3, a strip-shaped mounting groove 303 is opened, and the swing plate 5 has a certain width, the width of the swing plate 5 is adapted to the width of the mounting groove 303, and the length direction of the swing plate 5 extends in the length direction of the mounting groove 303, so that the swing plate 5 can swing in the mounting groove 303.
[0050] As a specific implementation, in order to ensure the swinging of the swing plate 5, the side wall of the mounting groove 303 close to the first end of the air blocking plate 4 is provided with an anti-dead angle arc surface, which can ensure that the swing plate 5 is installed more compactly in the mounting groove 303, and can also ensure that a certain gap is left to realize the swinging of the swing plate 5.
[0051] See also Figures 3 to 8 As shown, a limiting member 6 is provided in the mounting groove 303, the limiting member 6 is close to the air outlet 302, a mounting seat 522 is provided at the end of the swing plate 5 away from the first end 41, the mounting seat 522 is hinged to the limiting member 6, a through groove 601 is provided on the limiting member 6, and the second end 42 of the air blocking plate 4 is passed through the through groove 601 and faces the air outlet 302.
[0052] Specifically, since the swing plate 5 is installed in the mounting groove 303 as a whole, since the air blocking plate 4 is also hinged to the swing plate 5, the air blocking plate 4 has a certain length, and the air blocking plate 4 is also located in the mounting groove as a whole, in order to facilitate the hinge connection between the swing plate 5 and the air blocking plate 4, a limiting member 6 is provided in the mounting groove 303, and the limiting member 6 is a plate structure, and the mounting seat 522 can be either a hinge seat provided with a through hole, or two symmetrically arranged ear-shaped bosses, and the ear-shaped bosses are provided with through holes, and the mounting seat 522 is hinged to the limiting member 6 through a pin shaft, and one end of the swing plate 5 is hinged to the limiting member 6 through the mounting seat 522, and the other end of the swing plate 5 is hinged to the first end 41 of the air blocking plate 4. Since the second end 42 of the air blocking plate 4 is facing the air outlet 302, a through groove 601 is provided on the limiting member 6, so that even after the first end 41 of the air blocking plate 4 is hinged to the swing plate 5, the second end 42 of the air blocking plate 4 passes through the through groove 601 toward the air outlet 302.
[0053] In this embodiment, by setting a limiter 6 in the installation groove 303 and allowing the second end 42 of the air blocking plate 4 to pass through the through groove 601 of the limiter 6, the movement of the air blocking plate 4 can be effectively limited and guided. In this way, it can be ensured that the air blocking plate 4, under the push or pull of the swing plate 5, stably moves toward or away from the air outlet 302 along a predetermined trajectory, avoiding the air blocking plate 4 from deflecting or getting stuck during the movement, thereby ensuring the accuracy and reliability of the area adjustment of the air outlet 302. In addition, the limiter 6, the swing plate 5, the air blocking plate 4 and other components are integrated in the installation groove 303, making the layout of the entire adjustment mechanism more compact. This compact arrangement helps to save space, reduce the overall volume and weight of the compressor, and is also convenient for installation and maintenance. In addition, the through groove 601 on the limiter 6 provides a clear guide path for the second end 42 of the air blocking plate 4, so that the air blocking plate 4 can be accurately aligned with the air outlet 302 during movement. This high-precision guidance helps to achieve fine adjustment of the area of the air outlet 302, thereby better meeting the performance requirements of the compressor under different working conditions. By reasonably setting the limiter 6 and the through groove 601, this embodiment can simplify the connection structure between the air blocking plate 4 and the swing plate 5 and reduce the use of additional guide or support components. This simplified setting reduces the manufacturing cost and assembly difficulty of the system, and also improves the overall reliability and durability of the system.
[0054] As a specific implementation, the through groove 601 is used for the second end 42 of the air blocking plate 4 to pass through. In other embodiments, the through groove 601 can also be formed by leaving a certain gap between the stopper 6 and the mounting groove 303, so that the air blocking plate 4 is installed laterally in the mounting groove 303 as a whole. In order to better block the air outlet 302, the air blocking plate 4 is in a 7-shape, and the end with a larger cross-sectional area is the second end. The air blocking plate 4 is laterally arranged in the mounting groove 303, and one end of the cross-sectional area of the air blocking plate 4 passes through the through groove 601 toward the air outlet 302.
[0055] See also Figures 3 to 8 As shown, the guide structure 2 further includes an elastic member 7 , one end of the elastic member 7 is connected to the mounting groove 303 , and the other end of the elastic member 7 is connected to the second end surface 52 , and the elastic force of the elastic member 7 applies a second pressure to the second end surface 52 .
[0056] Specifically, the elastic member 7 is a spring, and both a limiting member 6 and an elastic member 7 are provided in the installation groove 303. Since one end of the swing plate 5 is hinged to the limiting member 6, the other end of the swing plate 5 swings with the limiting member 6 as a support point, driving the air blocking plate 4 to move. In order to prevent the elastic member 7 from affecting the swing of the swing plate 5, the elastic member 7 is close to the limiting member 6. When the compressor operates at a low frequency, the first pressure of the first end face 51 is greater than the second pressure of the second end face 52, that is, although the flow velocity of the circumferential flow motion is small, the pressure of the first end face 51 is large. At this time, the pressure borne by the first end face 51 is greater than the elastic force exerted by the elastic member 7 on the second end face 52. Therefore, the swing plate 5 actually swings toward the bottom wall of the mounting groove 303, and the elastic member 7 is in a compressed state. The swing plate 5 drives the air blocking plate 4 to move toward the air outlet 302; when the compressor operates at a high frequency, that is, the flow velocity of the circumferential flow motion is large, the pressure of the first end face 51 is smaller. Since there is no airflow between the swing plate 5 and the mounting groove 303, only the elastic member 7 exerts pressure on the second end face 52. At this time, the pressure borne by the first end face 51 is less than the elastic force exerted by the elastic member 7 on the second end face 52, the elastic member 7 is restored, the elastic member 7 is stretched, and the swing plate 5 pulls the air blocking plate 4 away from the air outlet 302.
[0057] In this embodiment, the second pressure applied by the elastic member 7 (such as a spring) to the second end face 52 provides a stable reference force for the movement of the swing plate 5. When the pressure borne by the first end face 51 is compared with the second pressure applied by the elastic member 7, the swing direction of the swing plate 5 can be judged more accurately. In addition, the presence of the elastic member 7 makes the system more responsive and reliable under different working conditions. Under low-frequency conditions, the first pressure is greater than the second pressure applied by the elastic member 7, the elastic member 7 is compressed, and the swing plate 5 moves toward the air outlet 302; under high-frequency conditions, the first pressure is less than the second pressure applied by the elastic member 7, the elastic member 7 is extended, and the swing plate 5 pulls the air blocking plate 4 away from the air outlet 302. This arrangement ensures that the system can quickly and accurately adjust the area of the air outlet 302 under various working conditions, and by using the elastic member 7 to apply the second pressure, other complex control devices or sensors can be omitted, simplifying the overall structure of the system. This simplified arrangement reduces manufacturing costs and maintenance difficulties, and the elastic member 7 (such as a spring) has the ability to absorb and release energy, which can play a certain buffering and shock-absorbing role during system operation, reducing the impact and vibration caused by pressure changes, which helps to improve the stability and durability of the system.
[0058] It is worth noting that, in the present embodiment, the air outlet 302 and the mounting groove 303 are arranged on the same side. When the crankshaft 102 rotates clockwise, a circumferential flow motion with clockwise flow is generated. Since the air outlet 302 is arranged on the side wall of the guide shell 3, the gas flowing out of the air outlet 302 can participate in the circumferential flow motion in the clockwise direction, and then perform subsequent oil and gas separation. Therefore, the flow rate of the gas flowing out of the air outlet 302 can also affect the effect of oil and gas separation to a certain extent. Especially when the compressor operates at a low frequency, this adjustment method of the present embodiment can increase the speed of the gas flowing out of the air outlet 302, and merge into the circumferential flow motion at a higher flow rate, thereby improving the oil and gas separation effect.
[0059] See also Figures 3 to 8 As shown, a mounting column 8 is disposed in the mounting groove 303 , and one end of the elastic member 7 facing away from the second end surface 52 is connected to the mounting column 8 .
[0060] In this embodiment, the mounting post 8 provides a fixed connection point for the elastic member 7, so that the elastic member 7 can stably apply elastic force. This stable support helps to ensure that the elastic member 7 can work reliably under different working conditions. By connecting the elastic member 7 to the mounting post 8, the installation process of the entire system can be simplified. The mounting post 8, as a fixed structure, makes the installation position of the elastic member 7 more clear and stable, which is convenient for maintenance and replacement. In addition, the setting of the mounting post 8 can reduce the possibility of displacement or offset of the elastic member 7 during operation, thereby improving the stability of the entire system. This stability is crucial to ensure the precise movement of the air blocking plate 4 and the accurate adjustment of the area of the air outlet 302.
[0061] See also Figures 3 to 8 As shown, the air guide structure 2 further includes a connecting rod 9 , one end of the connecting rod 9 is hinged to the swing plate 5 , and the other end of the connecting rod 9 is hinged to the first end 41 of the air blocking plate 4 .
[0062] Specifically, considering that the air blocking plate 4 moves linearly relative to the air outlet 302, the connecting rod 9 can transmit the swinging motion of the swing plate 5 to the air blocking plate 4. Since one end of the connecting rod 9 is hinged to the swing plate 5, and the other end is hinged to the first end 41 of the air blocking plate 4, when the swing plate 5 swings, the air blocking plate 4 can be driven to move accordingly through the connecting action of the connecting rod 9. The setting of the connecting rod 9 can also convert the rotation of the swing plate 5 into the linear movement of the air blocking plate 4. The setting of the connecting rod 9 mechanism can optimize the movement performance and transmission efficiency of the machine. Through reasonable kinematic analysis and optimization, the relative position and size relationship between each component can be determined, thereby improving the movement accuracy and stability of the machine. In other embodiments, if the connecting rod 9 mechanism needs to be adjusted or repaired, it can be achieved by changing the length and connection method of the connecting rod 9 without making large-scale changes to the entire machine.
[0063] See also Figures 7 to 9 As shown, a first rotating shaft 521 is provided on the second end surface 52 , a second rotating shaft 401 is provided on the air blocking plate 4 , one end of the connecting rod 9 is hinged to the first rotating shaft 521 , and the other end of the connecting rod 9 is hinged to the second rotating shaft 401 .
[0064] In this embodiment, the hinge structure allows the connecting rod 9 to rotate freely within a certain range. This flexibility enables the system to adapt to different motion requirements and working conditions. At the same time, two rotating shafts are set as hinge points. The stable connection of the hinge points also improves the stability of the entire mechanism and reduces errors and vibrations during the motion process.
[0065] See also Figures 7 to 9 As shown, the second rotating shaft 401 is tiltedly arranged on the air blocking plate 4, and a boss 411 is arranged at one end of the second rotating shaft 401 away from the air blocking plate 4. An angle is formed between the central axis of the boss 411 and the horizontal line of the end surface of the air blocking plate 4, and the angle range is 30° to 60°.
[0066] In this embodiment, the preferred angle is 45°. Considering that only one end of the air blocking plate 4 is to pass through the through slot 601, and the other end is a relatively movable end, a certain downward pressing force must be retained to prevent this end from tilting. Moreover, the function of the mechanism itself is to push and pull the air blocking plate 4. The boss 411 is also inclined relative to the horizontal direction of the air blocking plate 4 to ensure that the connecting rod 9 can apply a pushing and pulling force to the air blocking plate 4. In other embodiments, the angle may also be 30° or 60° or other suitable angles.
[0067] See also Figures 1 to 9 As shown, it also includes a casing 10, the pump body assembly 1 is installed in the casing 10, the guide housing 3 is installed on the inner wall of the casing 10, the guide housing 3 includes a panel 31, a first outer edge plate 32 and a second outer edge plate 33, the cross section of the panel 31 is concave, the concave side of the panel 31 is vertically installed on the casing 10, the two sides of the concave side of the panel 31 are respectively connected to the first outer edge plate 32 and the second outer edge plate 33, the inner wall of the first outer edge plate 32 and the inner wall of the second outer edge plate 33 are respectively connected to the casing 10, The first outer edge plate 32 and the second outer edge plate 33 of the body are mounted on the casing 10 by welding or gluing; an air inlet 301 is arranged at the top of the panel 31, an air outlet 302 is arranged on the side wall of the panel 31, and a mounting groove 303 is arranged on the first outer edge plate 32 corresponding to the air outlet 302, the air baffle plate 4 and the swing plate 5 are mounted in the mounting groove 303, the first end 41 of the air baffle plate 4 is movably connected to the side wall of the panel 31, and the air outlet 302 and the air baffle plate 4 are located on the same side of the panel 31.
[0068] In this embodiment, after the concave side of the panel 31 is installed on the casing 10, it is equivalent to forming a chamber between the concave side of the panel 31 and the casing 10, and the air inlet 301 and the air outlet 302 are both connected to the chamber. The panel 31, the first outer edge plate 32 and the second outer edge plate 33 of the flow guide housing 3 together constitute a specific gas flow space. The concave cross-section of the panel 31 allows the gas to flow along a predetermined path, enter from the air inlet 301 at the top, and after passing through the internal flow guide, flow out from the air outlet 302 on the side wall. The flow guide housing 3 is installed on the inner wall of the casing 10. This installation method provides stable support for the flow guide structure 2. The first outer edge plate 32 and the second outer edge plate 33 of the flow guide housing 3 are respectively connected to the casing 10 to form a stable structural frame that can withstand the air flow pressure and mechanical vibration generated during the operation of the compressor.
[0069] See also Figures 1 to 9 As shown, it also includes an upper bracket 11 for supporting the pump body assembly 1, and the guide shell 3 is arranged below the upper bracket 11. The outer edge of the upper bracket 11 is provided with an exhaust groove 111, one end of the exhaust groove 111 is connected to the exhaust port 101, and the other end of the exhaust groove 111 is located above the air inlet 301. The casing 10 has a motor upper cavity 110, and the fluid discharged from the pump body assembly 1 flows through the exhaust groove 111 and the air inlet 301 in sequence, and the air outlet 302 guides the fluid to the motor upper cavity 110.
[0070] Specifically, the rotor of the motor 103 is installed on the crankshaft 102, and a certain space is left between the upper bracket 11 and the motor 103 in the circumferential direction to form an upper chamber 110 of the motor. When the crankshaft 102 rotates, a circumferential flow motion is generated in the upper chamber 110 of the motor. After the guide shell 3 is installed on the casing 10, the guide structure 2 is actually located in the upper chamber 110 of the motor as a whole. When the airflow is discharged from the air outlet 302, it can participate in the circumferential flow motion, and this arrangement can ensure that the gas flowing out of the exhaust groove 111 first flows into the guide structure 2, and then is guided to the upper chamber 110 of the motor.
[0071] In this embodiment, a clear gas flow path is formed by the cooperation of the exhaust groove 111 of the upper bracket 11 and the air inlet 301 and the air outlet 302 of the guide housing 3. The fluid discharged from the pump body assembly 1 first flows through the exhaust groove 111 of the upper bracket 11, then enters the air inlet 301 of the guide housing 3, flows out from the air outlet 302 after being guided, and finally is guided to the upper chamber 110 of the motor. The installation position and structural setting of the guide housing 3 enable it to stably withstand the air flow pressure and mechanical vibration generated during the operation of the compressor. At the same time, the exhaust groove 111 of the upper bracket 11 is connected to the air inlet 301 of the guide housing 3, ensuring the continuity and stability of the gas flow. In addition, by locating the guide structure 2 as a whole in the upper chamber 110 of the motor, the gas discharged from the air outlet 302 can directly participate in the circumferential flow motion in the upper chamber 110 of the motor, reducing the intermediate links and energy loss of the gas flow, and improving the overall efficiency of the system.
[0072] It is worth noting that the greater the velocity of the circumferential flow, the higher the possibility that the mixed gas in the circumferential flow area will impact the inner wall of the casing 10, and the oil circulation rate will also decrease. When the compressor is running at high frequency, the rotation speed of the crankshaft 102 increases, the circumferential flow increases, and the oil circulation rate itself is relatively low under high-frequency conditions. At this time, continuing to maintain a smaller outlet will certainly increase the flow rate. However, the current situation is that high-frequency power consumption is high and low-frequency oil circulation rate is high. This embodiment is based on this point to set the guide structure 2 to adjust this phenomenon. Therefore, the choice of increasing the outlet area at high frequency is to reduce the outlet pressure in order to reduce power consumption when the oil circulation rate has been met.
