DETAILED DESCRIPTION
[0034] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The description of the at least one exemplary embodiment is actually only illustrative, but not as any limitation on the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without any creative work, fall within the scope of protection of the present application.
[0035] In the description of the present application, it should be understood that the orientation words such as “front, back, up, down, left, right”, “transverse, vertical, perpendicular, horizontal” and “top, bottom” and the like indicate the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present application and simplifying the description, and do not indicate and imply that the indicated device or element must have a particular orientation or be constructed and operated in a particular orientation, therefore cannot be understood as a limitation on the scope of protection of the present application; the orientation words “inner, outer” refer to the inner and outer relative to the contour of each component.
[0036] For purposes of the description hereinafter, spatial relative terms, such as "above", "below", "upper", "lower", and the like, can be used to describe the relative position of one element or feature to another element or feature as illustrated in the figures. It will be understood that the spatial relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientations depicted in the figures. For example, if the device in the figures is turned over, elements described as "above" or "up" other elements or features would then be oriented "below" or "down" the other elements or features. Likewise, if devices in the figures are turned over, elements described as "below" or "down" other elements or features would then be oriented "above" or "up" the other elements or features.
[0037] With reference to the drawings Figures 1 to 6 As shown, according to the embodiment of the present application, a compressor is provided, comprising a pump body assembly 1 and a flow guide structure 2; the pump body assembly 1 has an exhaust port 101, and the flow guide structure 2 is arranged on the exhaust path of the exhaust port 101; the flow guide structure 2 comprises a flow guide shell 3 and a gas blocking plate 4, the flow guide shell 3 has an air inlet 301 and an air outlet 302 which are in communication with each other, and the air inlet 301 is in communication with the exhaust port 101, the first end 41 of the gas blocking plate 4 is movably connected with the flow guide shell 3, and the second end 42 of the gas blocking plate 4 is movably arranged relative to the air outlet 302, so that the gas blocking plate 4 can shield part of the air outlet 302 or move 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 gas is driven to flow around by the crankshaft 102, and the flow around is an important aid for the separation of the high-temperature and high-pressure lubricating oil and the refrigerant mixture in the compressor, and the change of the flow rate of the flow around can separate the two mixed fluids, and the flow around will make the mixed fluid hang on the components of the compressor, forming a sudden drop in speed to 0, and the lubricating oil will separate and hang on the components to form an oil film, slowly flowing to the oil pool at the bottom of the compressor, and then making the lubricating oil flowing out of the exhaust pipe of the compressor less, so as to achieve 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, and 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 flow guide structure 2 from the gas inlet port 301, the gas is separated from the oil and flows out of the gas outlet port 302. The area of the gas outlet port 302 determines the outflow rate and the outflow speed of the gas. The operating conditions of the compressor are different, and the rotating speed of the crankshaft 102 of the pump body assembly 1 is also different. The outflow rate and the outflow speed of the gas are different. When the compressor operates at a low frequency, the rotating speed of the crankshaft 102 is slow, and the flow rate 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 is high. In this case, the gas blocking plate 4 blocks part of the gas outlet port 302, the gas passing area of the gas outlet port 302 is reduced, the flow rate of the gas flowing out of the gas outlet port 302 is increased, and the flow rate is increased. The flow rate is increased, the oil-gas separation is accelerated, and the oil circulation rate is reduced. When the compressor operates at a high frequency, the rotating speed of the crankshaft 102 is fast, and the flow rate is large, so that the lubricating oil and the refrigerant mixture can be fully separated from the oil. That is, the gas does not need to have a high outflow speed at the gas outlet port 302. However, when the compressor operates at a high frequency, although the oil circulation rate is low, the power consumption of the compressor is high. The gas blocking plate 4 no longer blocks the gas outlet port 302, but is away from the gas outlet port 302, so that the gas outlet port 302 is fully opened. At this time, the amount of gas flowing out of the gas outlet port 302 is large, and the outflow speed of the gas is low, which reduces the exhaust resistance of the gas and reduces the power consumption of the compressor.
[0040] In the embodiment, compared with the conventional gas flowing out of the pump body assembly 1 directly participating in the flow movement, the flow guide structure 2 is arranged on the exhaust path of the exhaust port 101. The flow guide structure 2 can adjust the amount of gas participating in the flow movement and the flow rate of the gas. Moreover, the flow guide structure 2 provides a clear flow path for the gas flowing out of the exhaust port 101. Through the arrangement of the flow guide housing 3, the gas is guided to enter the flow guide structure 2 from the gas inlet port 301, and then flows out of the gas outlet port 302. This orderly guiding action can avoid the disorderly diffusion of the gas in the compressor. The gas blocking plate 4 can adjust the outflow speed of the gas by blocking or moving away from the gas outlet port 302. The adjustability of the gas blocking plate 4 enables it to adapt to different operating conditions of the compressor. This flexibility enables the compressor to maintain high working efficiency and performance under various operating conditions, improves the applicability and reliability of the compressor, and optimizes the flow state and speed of the gas by adjusting the area of the gas outlet port 302 according to the operating conditions of the compressor, thereby improving the overall efficiency of the system and enabling the compressor to better adapt to different load changes. By adjusting the size of the gas outlet port 302, the problem that the existing method of reducing the oil circulation rate of the compressor increases the power consumption of the compressor at a high frequency and reduces the power consumption of the compressor but increases the oil circulation rate at a low frequency is overcome.
[0041] It is worth mentioning that in the embodiment, the flow rate and flow velocity of the gas participating in the flow around movement can be adjusted by setting the flow guide structure 2. The movable mode of the gas blocking plate 4 can reasonably set the position thereof, and the gas flow change can drive the gas blocking plate 4 to move. The related structure can be set to automatically drive the gas blocking plate 4 to move according to the change of the compressor operation. The swing lever linkage structure can be set, and the gas flow acts on the swing lever linkage structure, and the swing lever linkage structure drives the gas blocking plate 4 to move. In the embodiment, the specific moving mode of the gas blocking plate 4 can be flexibly selected to ensure that the gas blocking plate 4 can move when the working condition of the compressor changes.
[0042] For reference Figures 3 to 8 As shown in the figure, the flow guide structure 2 further comprises a swing plate 5, one end of the swing plate 5 is movably connected with the flow guide shell 3, the other end of the swing plate 5 is movably connected with the first end 41 of the gas blocking plate 4, the swing plate 5 has opposite first and second end faces 51 and 52, the second end face 52 faces the gas blocking plate 4, and after the gas blocking plate 4 is hinged with the swing plate 5, the gas 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 bear the first pressure, and the second end face 52 is used to bear the second pressure. The first and second end faces 51 and 52 form a pressure difference, and the swing of the swing plate 5 drives the gas blocking plate 4 to move. Specifically, the swing plate 5 is used to drive the gas blocking plate 4 to move in the embodiment. When the compressor operates in a low-frequency working condition, the first end face 51 bears a larger pressure, and although the second end face 52 also bears a certain pressure, the first pressure is greater than the second pressure, and there is a pressure difference between the first and second end faces 51 and 52. The side with larger pressure drives the swing plate 5 to swing towards the gas blocking plate 4. At this time, the swing plate 5 drives the first end 41 of the gas blocking plate 4 to move, and further drives the second end 42 of the gas blocking plate 4 to move towards the gas outlet 302, so as to block part of the gas outlet 302 and increase the flow velocity of the gas at the gas outlet 302. When the compressor operates in a high-frequency working condition, the pressure borne by the first end face 51 decreases, and the second pressure is greater than the first pressure. There is still a pressure difference between the first and second end faces 51 and 52. The side with larger pressure drives the swing plate 5 to swing away from the gas blocking plate 4. At this time, the swing plate 5 reversely drives the first end 41 of the gas blocking plate 4 to move, and further drives the second end 42 of the gas blocking plate 4 to move away from the gas outlet 302. The gas outlet 302 is completely opened, the flow velocity of the gas at the gas outlet 302 is reduced, and the exhaust resistance is reduced.
[0043] As a specific embodiment, the two ends of the swing plate 5 are respectively connected with the flow guide shell 3 and the gas blocking plate 4, and in the embodiment, the swing plate 5 is hinged at one end to the flow guide shell 3 and at the other end to the first end 41 of the gas blocking plate 4, that is, the rotation connection between the components is achieved. In other embodiments, flexible connection can also be used, for example, one end of the swing plate 5 is connected to the flow guide shell 3 through an elastic sheet, and the other end of the swing plate 5 is connected to the gas blocking plate 4 through a spring. In this way, when the gas flow pushes the swing plate 5, the elastic sheet deforms, the swing plate 5 swings to a certain angle, the swing plate 5 drives the spring to move, the spring pushes the gas blocking plate 4 to move and blocks part of the gas outlet 302, and under the action of gravity, the spring changes from the compressed state to the elongated state; when there is no pressure difference between the first end face 51 and the second end face 52, the swing plate 5 resets, pulls the spring to reset, the spring pulls the first end 41 of the gas blocking plate 4 to move reversely, the spring is compressed, and the gas outlet 302 is opened.
[0044] In the embodiment, the swing of the swing plate 5 pushes or pulls the gas blocking plate 4 to move, thereby automatically adjusting the area size of the gas outlet 302. In the low-frequency working condition, blocking part of the gas outlet 302 can increase the flow rate of the gas at the gas outlet 302, which is beneficial to accelerate the oil-gas separation and reduce the oil circulation rate; and in the high-frequency working condition, completely opening the gas outlet 302 can reduce the flow rate of the gas, reduce the exhaust resistance, and reduce the power consumption of the compressor. Through the optimization of 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 pressure difference between the first end face 51 and the second end face 52. This pressure difference-based adjustment method can accurately reflect the change of the gas pressure in the compressor, thereby making the adjustment of the system more stable and reliable, reducing the performance fluctuation and fault risk caused by improper adjustment, and the combination of the swing plate 5 and the gas blocking plate 4 can realize the automatic adjustment of the area of the gas outlet 302 without the need for additional complex control devices or sensors, thereby simplifying the overall structure of the system and reducing the manufacturing cost and maintenance difficulty of the system.
[0045] It is worth mentioning that the first pressure applied to the first end surface 51 in the embodiment is determined by the setting position of the swing plate 5, and the gas inlet 301 of the embodiment will have gas flowing in. By adjusting the setting position of the swing plate 5, the first end surface 51 is used to bear the pressure applied by the gas of the gas inlet 301, or the first end surface 51 is arranged towards the pump body assembly 1, and the circumferential flow generated by the rotation of the crankshaft 102 can flow through the first end surface 51 to apply the first pressure to the first end surface 51. Similarly, the second pressure borne by the second end surface 52 can also be realized in various ways, for example, by setting a structure to guide the gas flow to the second end surface 52, or the second end surface 52 has no gas flow passing through, but the second end surface 52 can be provided with an expansion piece or an elastic piece 7, which can apply a second pressure to the second end surface 52. By the above way, different pressures can be applied to the first end surface 51 and the second end surface 52 respectively, so as to realize the pressure difference between the two end surfaces, so that the swing plate 5 can swing.
[0046] For reference Figures 3 to 8 As shown in the figure, the side wall of the flow guide shell 3 is provided with a mounting groove 303, and the swing plate 5 is mounted in the mounting groove 303. The gas outlet 302 and the mounting groove 303 are located on the same side of the flow guide shell 3, the first end surface 51 faces the pump body assembly 1, and the second end surface 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 surface 51, when the first pressure is greater than the second pressure, the baffle plate 4 blocks part of the gas outlet 302; when the first pressure is less than the second pressure, the baffle plate 4 is away from the gas outlet 302.
[0047] Specifically, after the swing plate 5 is installed in the mounting groove 303, one end of the swing plate 5 is hinged to the flow guide shell 3, and the other end extends into the groove. The swing plate 5 is installed in the mounting groove 303 as a whole. The swing plate 5 is a plate structure, the first end face 51 faces the pump body assembly 1, and the second end face 52 faces the mounting groove 303. When the crankshaft 102 of the pump body assembly 1 rotates, the flow movement will flow along the circumferential direction of the end face of the flow guide shell 3. The airflow generated by the flow movement will also flow through the swing plate 5. The circumferential flow generated by the rotation of the crankshaft 102 exerts a first pressure on the first end face 51. Due to different operating conditions of the compressor, the flow velocity of the flow movement is different, and the first pressure exerted is also different. When the compressor operates in a low-frequency operating condition, the flow velocity of the flow movement is small, and the pressure borne by the first end face 51 is relatively large. At this time, the first pressure is greater than the second pressure, and the swing plate 5 swings towards the bottom wall of the mounting groove 303. At this time, the swing plate 5 pushes the first end 41 of the resistance plate 4 to move, and further pushes the second end 42 of the resistance plate 4 to move towards the gas outlet 302, thereby shielding part of the gas outlet 302, and increasing the flow velocity of the gas at the gas outlet 302. When the compressor operates in a high-frequency operating condition, the flow velocity of the flow movement is large, and the pressure borne by the first end face 51 is relatively small. At this time, the first pressure is less than the second pressure, and the swing plate 5 swings away from the bottom wall of the mounting groove 303. At this time, the swing plate 5 pulls the first end 41 of the resistance plate 4 to move, and further pulls the second end 42 of the resistance plate 4 away from the gas outlet 302, thereby opening the gas outlet 302 and reducing the flow velocity of the gas at the gas outlet 302.
[0048] In the present embodiment, the position of the resistance 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 exerted on the first end face 51 by the circumferential flow generated by the rotation of the pump body assembly 1 and the pressure of the second end face 52. This arrangement enables the system to automatically adjust according to the actual operating state (low-frequency or high-frequency operating condition) of the compressor without human intervention, thereby improving the intelligent level 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 pressure difference of the circumferential flow generated by the pump body assembly 1. This pressure-difference-based adjustment method can accurately reflect the gas pressure change in the compressor, thereby making the adjustment of the system more stable and reliable, and reducing the performance fluctuation and fault risk caused by improper adjustment. Moreover, by this method, the swing plate 5 and the resistance plate 4 can be automatically adjusted in real time according to the operating condition of the compressor. The swing of the swing plate 5 and the movement of the resistance plate 4 can quickly respond to the change of the operating condition of the compressor. This fast response capability helps to timely adjust the area of the gas outlet 302 and optimize the gas flow state under different operating conditions.
[0049] As a specific embodiment, a strip-shaped mounting groove 303 is formed in the side wall of the flow guide shell 3 in the axial direction of the flow guide shell 3, the swing plate 5 has a certain width, the width of the swing plate 5 is matched with 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 embodiment, in order to ensure the swing of the swing plate 5, the side wall of the mounting groove 303 close to the first end of the baffle plate 4 is provided with an anti-corner dead angle arc surface, which can ensure that the swing plate 5 is more compactly mounted in the mounting groove 303, and also ensure that there is a certain gap to realize the swing of the swing plate 5.
[0051] For reference, Figures 3 to 8 As shown in the figure, a limiting piece 6 is arranged in the mounting groove 303, the limiting piece 6 is close to the air outlet 302, one end of the swing plate 5 away from the first end 41 is provided with a mounting seat 522, the mounting seat 522 is hinged with the limiting piece 6, the limiting piece 6 is provided with a through slot 601, and the second end 42 of the baffle plate 4 is arranged in the through slot 601 and faces the air outlet 302.
[0052] Specifically, since the swing plate 5 is installed in the mounting groove 303 as a whole, and the baffle plate 4 is also hinged with the swing plate 5, the baffle plate 4 has a certain length, and the baffle plate 4 is also located in the mounting groove as a whole, in order to more conveniently hinge the swing plate 5 with the baffle plate 4, the limiting piece 6 is arranged in the mounting groove 303, the limiting piece 6 is a plate structure, the mounting seat 522 can be a hinge seat provided with a through hole, or two symmetrical ear-shaped bosses provided with a through hole, the mounting seat 522 is hinged with the limiting piece 6 through a pin shaft, one end of the swing plate 5 is hinged with the limiting piece 6 through the mounting seat 522, and the other end of the swing plate 5 is hinged with the first end 41 of the baffle plate 4. Since the second end 42 of the baffle plate 4 faces the air outlet 302, the through slot 601 is arranged on the limiting piece 6, so that even if the first end 41 of the baffle plate 4 is hinged with the swing plate 5, the second end 42 of the baffle plate 4 passes through the through slot 601 and faces the air outlet 302.
[0053] In the embodiment, the movement of the air resistance plate 4 is effectively limited and guided by arranging the limiting piece 6 in the mounting groove 303 and making the second end 42 of the air resistance plate 4 pass through the through groove 601 of the limiting piece 6. In this way, it can be ensured that the air resistance plate 4 is stably moved along the predetermined track towards or away from the air outlet 302 under the pushing or pulling of the swing plate 5, avoiding the air resistance plate 4 from deviating or jamming during the movement, thereby ensuring the accuracy and reliability of the area adjustment of the air outlet 302. Moreover, the components such as the limiting piece 6, the swing plate 5 and the air resistance plate 4 are integrated in the mounting groove 303, so that the layout of the entire adjustment mechanism is 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 limiting piece 6 provides a clear guide path for the second end 42 of the air resistance plate 4, so that the air resistance plate 4 can be accurately aligned with the air outlet 302 during the 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. The present embodiment can simplify the connection structure of the air resistance plate 4 and the swing plate 5 by reasonably arranging the limiting piece 6 and the through groove 601, and reduce the use of additional guide or support components. This simplified arrangement 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 for the second end 42 of the air resistance plate 4 to pass through. In other embodiments, the through groove 601 can also be a certain gap left between the limiting piece 6 and the mounting groove 303, so that the air resistance plate 4 is installed laterally in the mounting groove 303. In order to better block the air outlet 302, the air resistance plate 4 is in the shape of a 7, and the end with a larger cross-sectional area is the second end. The air resistance plate 4 is laterally arranged in the mounting groove 303, and one end of the air resistance plate 4 passes through the through groove 601 towards the air outlet 302.
[0055] For reference Figures 3 to 8 As shown in the figure, the flow guide structure 2 further includes an elastic piece 7, one end of the elastic piece 7 is connected with the mounting groove 303, and the other end of the elastic piece 7 is connected with the second end face 52. The elastic force of the elastic piece 7 applies a second pressure to the second end face 52.
[0056] Specifically, the elastic member 7 is a spring, and both the limiting member 6 and the elastic member 7 are arranged in the mounting 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 around the limiting member 6 as a support point to drive the air resistance plate 4 to move. In order to avoid the influence of the elastic member 7 on the swing of the swing plate 5, the elastic member 7 is close to the limiting member 6. When the compressor operates in a low-frequency working condition, the first pressure of the first end surface 51 is greater than the second pressure of the second end surface 52, that is, the circumferential flow movement has a small flow rate, but the pressure of the first end surface 51 is large. At this time, the pressure borne by the first end surface 51 is greater than the elastic force exerted by the elastic member 7 on the second end surface 52, so in fact the swing plate 5 swings towards 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 resistance plate 4 to move towards the air outlet 302. When the compressor operates in a high-frequency working condition, that is, the circumferential flow movement has a large flow rate, the pressure of the first end surface 51 is small. 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 surface 52. At this time, the pressure borne by the first end surface 51 is smaller than the elastic force exerted by the elastic member 7 on the second end surface 52, so the elastic member 7 can recover, the elastic member 7 is elongated, and the swing plate 5 pulls the air resistance plate 4 away from the air outlet 302.
[0057] In the present embodiment, the second pressure exerted by the elastic member 7 (such as a spring) on the second end surface 52 provides a stable reference force for the movement of the swing plate 5. When the pressure borne by the first end surface 51 is compared with the second pressure exerted by the elastic member 7, the swing direction of the swing plate 5 can be more accurately judged. In addition, the presence of the elastic member 7 makes the response of the system in different working conditions more sensitive and reliable. In a low-frequency working condition, the first pressure is greater than the second pressure exerted by the elastic member 7, the elastic member 7 is compressed, and the swing plate 5 moves towards the air outlet 302. In a high-frequency working condition, the first pressure is smaller than the second pressure exerted by the elastic member 7, the elastic member 7 is elongated, and the swing plate 5 pulls the air resistance 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 in various working conditions. Moreover, by using the elastic member 7 to exert 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 difficulty. The elastic member 7 (such as a spring) has the ability to absorb and release energy, which can play a certain buffering and damping role during the operation of the system, reducing the impact and vibration caused by pressure changes, which helps to improve the stability and durability of the system.
[0058] It is worth mentioning that in this embodiment, the gas outlet 302 and the mounting groove 303 are arranged on the same side, and when the crankshaft 102 rotates clockwise, a clockwise circumferential flow motion is generated. Since the gas outlet 302 is arranged on the side wall of the flow guide shell 3, the gas flowing out of the gas outlet 302 can participate in the circumferential flow motion in the same direction, and then perform subsequent oil-gas separation. Therefore, the flow rate of the gas flowing out of the gas outlet 302 can also affect the oil-gas separation effect to some extent. Especially when the compressor operates in a low-frequency working condition, this adjustment method of the embodiment can increase the speed of the gas flowing out of the gas outlet 302, so that the gas flows into the circumferential flow motion at a larger flow rate, thereby improving the oil-gas separation effect.
[0059] Referring to Figures 3 to 8 As shown in the figure, the mounting groove 303 is provided with a mounting column 8, and one end of the elastic member 7 away from the second end face 52 is connected with the mounting column 8.
[0060] In this embodiment, the mounting column 8 provides a fixed connection point for the elastic member 7, so that the elastic member 7 can stably exert the 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 column 8, the installation process of the entire system can be simplified. The mounting column 8 serves as a fixed structure, so that the installation position of the elastic member 7 is more definite and stable, which is convenient for maintenance and replacement. Moreover, the setting of the mounting column 8 can reduce the possibility of displacement or deviation of the elastic member 7 during work, thereby improving the stability of the entire system. This stability is crucial for ensuring the accurate movement of the baffle plate 4 and the accurate adjustment of the area of the gas outlet 302.
[0061] Referring to Figures 3 to 8 As shown in the figure, the flow guide structure 2 further includes a connecting rod 9, one end of the connecting rod 9 is hinged with the swing plate 5, and the other end of the connecting rod 9 is hinged with the first end 41 of the baffle plate 4.
[0062] Specifically, considering that the baffle plate 4 moves linearly relative to the gas outlet 302, the connecting rod 9 can transmit the swing motion of the swing plate 5 to the baffle plate 4. Since one end of the connecting rod 9 is hinged with the swing plate 5 and the other end is hinged with the first end 41 of the baffle plate 4, when the swing plate 5 swings, it can drive the baffle plate 4 to move correspondingly 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 baffle 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 the components can be determined, thereby improving the movement accuracy and stability of the machine. In other embodiments, if it is necessary to adjust or maintain the connecting rod 9 mechanism, it can be realized by changing the length and connection mode of the connecting rod 9 without the need to make large-scale changes to the entire machine.
[0063] Referring to Figures 7 to 9 As shown in the figure, the second end surface 52 is provided with a first rotating shaft 521, the air resistance plate 4 is provided with a second rotating shaft 401, 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 hinged structure allows the connecting rod 9 to rotate freely within a certain range, and this flexibility enables the system to adapt to different movement requirements and working condition changes. At the same time, the two rotating shafts are provided as hinged points, and the stable connection of the hinged points also improves the stability of the entire mechanism, reducing errors and vibrations during movement.
[0065] Referring to Figures 7 to 9 As shown in the figure, the second rotating shaft 401 is inclinedly arranged on the air resistance plate 4, and the end of the second rotating shaft 401 away from the air resistance plate 4 is provided with a boss 411, the central axis of the boss 411 and the horizontal line of the end surface of the air resistance plate 4 have an included angle, and the angle range of the included angle is 30°-60°.
[0066] In this embodiment, the angle of the included angle is preferably 45°. Considering that the air resistance plate 4 has only one end to pass through the through slot 601, the other end is a relatively movable end, so a certain downward pressing force needs to be maintained to prevent the end from being raised, and the mechanism itself is arranged to push and pull the air resistance plate 4. The boss 411 is also inclinedly arranged relative to the horizontal direction of the air resistance plate 4 to ensure that the connecting rod 9 can exert a pushing and pulling force on the air resistance plate 4. In other embodiments, the angle of the included angle can also be 30° or 60° or other suitable angles.
[0067] Referring to Figures 1 to 9 As shown in the figure, the pump body assembly 1 is installed in the machine shell 10, and the flow guide shell 3 is installed on the inner wall of the machine shell 10. The flow guide shell 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 in the shape of a concave character, and the concave side of the panel 31 is vertically installed on the machine shell 10. The two sides of the concave side of the panel 31 are connected with the first outer edge plate 32 and the second outer edge plate 33, respectively. The inner wall of the first outer edge plate 32 and the inner wall of the second outer edge plate 33 are connected with the machine shell 10, respectively. Specifically, the first outer edge plate 32 and the second outer edge plate 33 are installed on the machine shell 10 by welding or pasting. The top end of the panel 31 is provided with an air inlet 301, and the side wall of the panel 31 is provided with an air outlet 302. The first outer edge plate 32 corresponding to the air outlet 302 is provided with a mounting recess 303, and the air resistance plate 4 and the swing plate 5 are installed in the mounting recess 303. The first end 41 of the air resistance plate 4 is movably connected with the side wall of the panel 31, and the air outlet 302 and the air resistance plate 4 are located on the same side of the panel 31.
[0068] In the embodiment, after the recessed side of the panel 31 is mounted on the casing 10, a cavity is formed between the recessed side of the panel 31 and the casing 10, the air inlet 301 and the air outlet 302 are communicated with the cavity, and the panel 31, the first outer edge plate 32 and the second outer edge plate 33 of the flow guide housing 3 jointly form a specific gas flow space. The recessed cross section of the panel 31 is configured to enable the gas to flow along a predetermined path, i.e., from the air inlet 301 at the top end, through the internal flow guide, and out of the air outlet 302 at the side wall. The flow guide housing 3 is mounted on the inner wall of the casing 10, which 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 with the casing 10, forming a stable structural frame that can withstand the gas flow pressure and mechanical vibration generated during the operation of the compressor.
[0069] With reference to Figures 1 to 9 As shown, the upper support 11 for supporting the pump body assembly 1 is further included, the flow guide housing 3 is arranged below the upper support 11, the outer edge of the upper support 11 is provided with an exhaust groove 111, one end of the exhaust groove 111 is communicated with 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, the fluid discharged by 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 mounted on the crankshaft 102, and the upper support 11 and the motor 103 are spaced in the circumferential direction to form the motor upper cavity 110. When the crankshaft 102 rotates, a circumferential flow motion is generated in the motor upper cavity 110. After the flow guide housing 3 is mounted on the casing 10, the flow guide structure 2 is actually also located in the motor upper cavity 110. Since the gas discharged from the air outlet 302 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 flow guide structure 2 and then is guided to the motor upper cavity 110.
[0071] In the embodiment, by the cooperation of the exhaust groove 111 of the upper support 11 and the air inlet 301 and the air outlet 302 of the flow guide shell 3, a clear gas flow path is formed, the fluid discharged by the pump body assembly 1 first flows through the exhaust groove 111 of the upper support 11, then enters the air inlet 301 of the flow guide shell 3, flows out from the air outlet 302 after flow guiding, and is finally guided into the upper cavity 110 of the motor. The installation position and structure of the flow guide shell 3 are arranged to stably bear the gas flow pressure and mechanical vibration generated during the operation of the compressor, and at the same time, the exhaust groove 111 of the upper support 11 is in communication with the air inlet 301 of the flow guide shell 3, which ensures the continuity and stability of the gas flow. In addition, by locating the flow guide structure 2 in the upper cavity 110 of the motor as a whole, the gas discharged from the air outlet 302 can directly participate in the circumferential flow motion in the upper cavity 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 flow velocity of the flow around, the higher the possibility of the mixed gas in the flow around area impacting the inner wall of the casing 10, and the oil circulation rate will also be reduced. When the compressor operates at a high frequency, the rotational speed of the crankshaft 102 increases, and the flow around increases. The oil circulation rate is already low under high-frequency working conditions, and the outlet is kept small at this time, which further increases the flow velocity. However, the current situation is that the power consumption is high at high frequency, and the oil circulation rate is high at low frequency. The flow guide structure 2 is arranged in the embodiment to adjust this phenomenon, and therefore, the outlet area is increased at high frequency, which is to reduce the outlet pressure under the condition that the oil circulation rate has been satisfied, so as to reduce the power consumption.
