Description

Technical Field

[0001] This utility model relates to the field of compressor technology, and more specifically, to an air intake component. Background Technology

[0002] In the existing technology, the intake component design of rotary compressors usually adopts an outward-folding structure to connect the intake pipe and the upper cylinder. That is, the intake pipe passes through the inside of the outward-folding structure of the upper cylinder to improve the stability of the intake component structure.

[0003] However, while the outward-folding structure can alleviate stress concentration to some extent, the airflow may become unstable when it enters due to the angle between its interior and the intake pipe, resulting in eddies or impacts. This can lead to increased noise and vibration during compressor operation, affecting the overall performance of the equipment and the user experience. Utility Model Content

[0004] This utility model provides an air intake component to solve the problem that the existing technology usually uses an outward-folding structure to connect the air intake pipe and the upper cylinder, which easily generates vortices or impacts when the airflow enters, thus causing the compressor to have high noise during operation.

[0005] This utility model provides an air intake component, which includes: a flow pipe having an air inlet end and an air outlet end; a cylinder having a flow cavity communicating with the air outlet end, the end of the cylinder having an outward-flaring structure and a guide part, the outward-flaring structure being sleeved on the outer periphery of the air outlet end and fixedly connected thereto, and the guide part being located on the side of the outward-flaring structure facing the flow cavity, used to guide the backflowing gas in the flow cavity to avoid gas impacting the air intake component.

[0006] Furthermore, the cylinder includes a middle cylinder, a first end cap, and a second end cap. The first end cap is located at the end of the middle cylinder and forms a flow cavity with the middle cylinder. The second end cap is located at the end of the first end cap away from the middle cylinder and outside the flow cavity. A flow tube passes through the first end cap and the second end cap. The second end cap has an outward-folding structure, and the first end cap has a flow guide portion.

[0007] Furthermore, the first end cap includes a first body and a first flange. The first body is provided with a first through hole, and the flow tube is inserted into the first through hole. The first flange is located on the side of the first through hole facing the flow cavity. The first flange is circumferentially disposed on the edge of the first through hole and sleeved on the outer periphery of the flow tube. The connection between the first flange and the first body has a first transition structure, and the first transition structure forms a flow guide.

[0008] Furthermore, the second end cap includes a second body and a second flange. The second body is provided with a second through hole, and the flow tube is inserted into the second through hole. The second flange is located on the side of the second through hole away from the flow cavity. The second flange is circumferentially disposed on the edge of the second through hole and sleeved on the outer periphery of the flow tube. The extension direction of the second flange is opposite to the extension direction of the first flange, and the second flange forms an outward flange structure.

[0009] Furthermore, the first flange and the second flange are welded to the flow pipe respectively, and the first body is welded to the second body.

[0010] Furthermore, there is a gap between the second flange and the flow tube. The second flange, the first flange, and the flow tube cooperate to form a material holding space. The material holding space is connected to the gap. The first flange and the air outlet end of the flow tube are interference-fitted.

[0011] Furthermore, the outer diameter of the flow tube is A, the inner diameter of the second flange is B, and the inner diameter of the first flange is C, where 0mm < BA ≤ 0.2mm and 0mm < AC ≤ 0.1mm.

[0012] Furthermore, the maximum outer diameter of the first body is D, the maximum outer diameter of the second body is E, and the dimension of the second flange along the extension direction of the flow tube is F, where F≤E≤D.

[0013] Furthermore, the axis of the first through hole extends in the same direction as the axis of the second through hole, and the coaxiality is 0.1 mm.

[0014] Furthermore, along the axial direction of the flow pipe, the end of the air outlet is flush with the end of the outward-facing structure near the air outlet.

[0015] Furthermore, the cylinder includes a third end cap, which includes a third body and a third flange. The third body is provided with a third through hole, and the flow pipe is inserted into the third through hole. The third flange is annularly disposed on the edge of the third through hole and sleeved on the outer periphery of the flow pipe. The extension direction of the third flange is the same as the extension direction of the flow pipe, and the third flange forms an outward flange structure. There is a second transition structure between the third flange and the third body. The second transition structure protrudes toward the flow cavity from the end of the third flange near the air outlet, and the second transition structure forms a flow guide.

[0016] Furthermore, along the axial direction of the flow tube, the end of the outlet is flush with the end of the third flange near the flow cavity; the side of the second transition structure away from the flow cavity has a groove, which is formed by a stamping process.

[0017] By applying the technical solution of this utility model, the design of the guide section improves the flow state of gas after it enters the flow chamber. Gas flowing back within the flow chamber can return to the correct flow path through the guide section, making the airflow more stable and reducing the direct impact of the airflow on the flow pipe and cylinder. This reduces the noise level of the intake component during operation, optimizing the compressor's operating environment and improving user comfort. Simultaneously, the connection between the outward-flaring structure and the flow pipe creates a smooth transition at the joint, helping to disperse and reduce local stress. This optimizes the stress distribution at the connection point, effectively reducing stress and strain in the connection area, improving the load-bearing capacity and fatigue resistance of the connection, ensuring the structural stability and reliability of the intake component during long-term operation, and extending its service life.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0027] like Figures 1 to 3 As shown, Embodiment 1 of this utility model provides an air intake component, which includes a flow pipe 10 and a cylinder 20. The flow pipe 10 has an air inlet end 101 and an air outlet end 102. The cylinder 20 has a flow cavity 201, which communicates with the air outlet end 102. The end of the cylinder 20 has an outward-flaring structure 202 and a guide portion 203. The outward-flaring structure 202 is fitted around the outer periphery of the air outlet end 102 and fixedly connected thereto. The guide portion 203 is located on the side of the outward-flaring structure 202 facing the flow cavity 201, and is used to guide the backflowing gas within the flow cavity 201 to prevent gas from impacting the air intake component. The arrows indicate the direction of gas flow.

[0028] In this embodiment, the air intake component is connected to the compressor. In other embodiments, the air intake component can be used for other devices that require air intake or circulation.

[0029] By applying the technical solution of this utility model, the design of the guide section 203 improves the flow state of gas after it enters the flow chamber 201. Gas flowing back in the flow chamber 201 can return to the correct flow path through the guide section 203, making the airflow more stable and reducing the direct impact of the airflow on the flow pipe 10 and the cylinder 20. This reduces the noise level of the intake component during operation, optimizing the compressor's operating environment and improving user comfort. Simultaneously, the connection between the outward-flaring structure 202 and the flow pipe 10 creates a smooth transition at their joint, helping to disperse and reduce local stress. This optimizes the stress distribution at the connection between the outward-flaring structure 202 and the flow pipe 10, effectively reducing stress and strain in the connection area, improving the load-bearing capacity and fatigue resistance of the connection, ensuring the structural stability and reliability of the intake component during long-term operation, and extending the service life of the intake component.

[0030] like Figure 1 and Figure 2As shown, the cylinder 20 includes a middle cylinder 24, a first end cap 21, and a second end cap 22. The first end cap 21 is positioned over the end of the middle cylinder 24, forming a flow cavity 201. The second end cap 22 is positioned over the end of the first end cap 21 furthest from the middle cylinder 24 and is located outside the flow cavity 201. A flow pipe 10 passes through the first end cap 21 and the second end cap 22. The second end cap 22 has an outward-flaring structure 202, and the first end cap 21 has a flow guide 203. The combined design of the first end cap 21 and the second end cap 22 not only increases the overall rigidity of the intake component but also simplifies the end cap structure and facilitates manufacturing. Furthermore, the outward-flaring structure 202 on the second end cap 22 and the flow guide 203 on the first end cap 21 ensure the stability of the connection between the cylinder 20 and the flow pipe 10, reduce noise during operation of the intake component, and improve the rationality of the component layout.

[0031] like Figure 3 As shown, the first end cap 21 includes a first body 211 and a first flange 212. The first body 211 has a first through hole. The flow tube 10 passes through the first flange 212 and is inserted into the first through hole. The first flange 212 is located on the side of the first through hole facing the flow cavity 201. The first flange 212 is circumferentially arranged at the edge of the first through hole and is sleeved on the outer periphery of the flow tube 10. The first flange 212 can form a stable connection with the first body 211, thereby ensuring the sealing effect of the cylinder 20. The connection between the first flange 212 and the first body 211 has a first transition structure 213, which forms a guide portion 203. The design of the first transition structure 213 can cover the angle generated at the connection between the second end cap 22 and the flow pipe 10, and guide the airflow. This not only optimizes the stability of gas flow in the flow cavity 201 and reduces noise, but also helps to evenly distribute the pressure in the connection area between the first end cap 21, the second end cap 22 and the flow pipe 10, avoids stress concentration, and enhances the structural strength of the connection.

[0032] In this embodiment, the first transition structure 213 is an arc structure.

[0033] In other embodiments, the first transition structure 213 can be a polygonal structure or an irregular contour structure, as long as it can form a smooth transition between the first body 211 and the first flange 212, guide the airflow, and prevent the airflow from directly impacting the air intake component.

[0034] Furthermore, the second end cap 22 includes a second body 221 and a second flange 222. The second body 221 is provided with a second through hole. The flow tube 10 passes through the second flange 222 and is inserted into the second through hole. The second flange 222 is located on the side of the second through hole away from the flow cavity 201. The second flange 222 is circumferentially arranged at the edge of the second through hole and sleeved on the outer periphery of the flow tube 10. The extension direction of the second flange 222 is opposite to the extension direction of the first flange 212, and the second flange 222 forms an outward flange structure 202. The first flange 212 and the second flange 222 cooperate to form an inner and outer flange structure, which realizes the uniform distribution of stress, effectively disperses the stress concentration at the connection of the flow tube 10, improves the fatigue resistance of the intake component under airflow impact and operating vibration, and extends the service life of the intake component.

[0035] The first flange 212 and the second flange 222 are both formed by stamping, which makes the processing convenient and quick and allows for mass production.

[0036] Specifically, the first flange 212 and the second flange 222 are welded to the flow pipe 10, and the first body 211 is welded to the second body 221. Welding firmly connects the first flange 212, the flow pipe 10, and the second flange 222, improving the strength and reliability of the connection. Compared to other connection methods, welding provides a stable connection and a reliable seal, preventing refrigerant leakage during operation, reducing the need for seals, lowering assembly complexity, and improving overall cost-effectiveness.

[0037] In this embodiment, the second end cap 22 is made of copper. In other embodiments, the second end cap 22 may also be made of steel or other materials.

[0038] This application does not limit the welding process; welding methods such as laser welding, argon arc welding, or brazing can be selected according to actual needs.

[0039] like Figure 2 and Figure 3 As shown, there is a gap between the second flange 222 and the flow tube 10. The second flange 222, the first flange 212 and the flow tube 10 cooperate to form a material holding space. The material holding space is connected to the gap, thus providing sufficient filling space for the solder, avoiding loosening or breakage of the connection due to insufficient solder, ensuring the fullness and uniformity of the weld, and thus enhancing the stability and sealing of the welded connection.

[0040] The first flange 212 is interference-fitted with the outlet end 102 of the flow pipe 10, meaning the first flange 212 can be tightly fitted around the outer circumference of the flow pipe 10. This effectively prevents solder from flowing into the flow cavity 201 during welding, thus ensuring internal cleanliness and operational performance. Furthermore, it ensures the isolation of the flow cavity 201 from the outside environment, preventing refrigerant leakage and guaranteeing the operating efficiency and environmental friendliness of the refrigeration system.

[0041] like Figure 3 As shown, the outer diameter of the flow tube 10 is A, the inner diameter of the second flange 222 is B, and the inner diameter of the first flange 212 is C, where 0mm < BA ≤ 0.2mm and 0mm < AC ≤ 0.1mm. If BA ≤ 0mm, a gap sufficient to accommodate the solder cannot be formed between the second flange 222 and the flow tube 10, or the gap is too small. The solder may not be able to completely fill this narrow space, resulting in voids or incomplete fusion at the weld. This reduces the strength and airtightness of the welded joint and increases the risk of refrigerant leakage. If BA > 0.2mm, the gap between the second flange 222 and the flow tube 10 is too large. An excessively large gap may cause the solder to overfill during the welding process, or even overflow into unnecessary areas, wasting solder resources. This application, through the above settings, allows the solder sufficient space to flow and spread when heated and melted, ensuring that the solder can uniformly cover the welding area, forming a strong and airtight connection. It also helps to reduce the complexity of welding operations and improve assembly efficiency, ensuring the long-term stable operation and high performance of the air intake component. Specifically, BA can be selected from 0.08mm, 0.1mm, 0.13mm or 0.2mm, etc.

[0042] Specifically, if AC ≤ 0 mm, the first flange 212 cannot form an interference fit with the flow tube 10. During assembly, the first flange 212 cannot provide effective support for the flow tube 10, easily leading to structural instability at the connection point. Furthermore, the lack of a gap between the first flange 212 and the flow tube 10 may cause fluid leakage within the flow cavity 201. If AC > 0.1 mm, excessive compression will occur between the first flange 212 and the flow tube 10 during assembly, increasing assembly difficulty and potentially damaging the component surface. This application, through the above settings, ensures an interference fit between the first flange 212 and the flow tube 10, providing support for the flow tube 10, ensuring the sealing of the flow cavity 201, and guaranteeing smooth assembly and component integrity. Specifically, AC can be selected from 0.02 mm, 0.05 mm, 0.09 mm, or 0.1 mm, etc.

[0043] In other embodiments of this application, the difference between the inner diameter of the second flange 222 and the outer diameter of the flow pipe 10, and the difference between the outer diameter of the flow pipe 10 and the inner diameter of the first flange 212, can be selected as other preset values ​​according to actual working conditions and requirements.

[0044] like Figure 3 As shown, the maximum outer diameter of the first body 211 is D, the maximum outer diameter of the second body 221 is E, and the dimension of the second flange 222 along the extension direction of the flow pipe 10 is F, where F≤E≤D. If E is less than F, the structural strength of the second end cap 22 is low, and the contact area between the first body 211 and the second body 221 is small, resulting in low connection strength. If E is greater than D, the second body 221 protrudes from the first body 211 along the circumference of the cylinder 20, thus reducing the consistency and coordination of the overall structure of the cylinder 20. This application, through the above-mentioned design, ensures sufficient surface contact area between the first body 211 and the second body 221 during welding, enhancing the connection strength between the first end cap 21 and the second end cap 22. Simultaneously, it avoids the second body 221 protruding from the overall structure of the air intake component, ensuring the consistency and coordination of the overall structure of the cylinder 20 and reducing material waste.

[0045] In this embodiment, the first body 211 and the second body 221 are conical structures.

[0046] In other embodiments, the first body 211 and the second body 221 are arc-shaped structures, with the arc protruding in a direction away from the flow cavity 201.

[0047] The axis of the first through hole extends in the same direction as the axis of the second through hole, with a coaxiality of 0.1 mm. The machining error of the straightness of the second flange 222 and the first flange 212 does not exceed 0.1 mm. This configuration ensures the alignment of the flow pipe 10 with the first end cap 21 and the second end cap 22 during assembly. This maintains a uniform gap between the flange structure and the flow pipe 10, allowing the welding flux to fully fill the welding area during welding, thus enhancing the stability and reliability of the connection. Simultaneously, it allows the airflow to flow smoothly along a straight path when entering the flow cavity 201, avoiding airflow turbulence and increased resistance caused by aperture misalignment, improving gas flow efficiency, reducing energy loss, and thereby enhancing the operating efficiency and performance of the intake component.

[0048] like Figure 3 As shown, along the axial direction of the flow pipe 10, the end of the outlet end 102 is flush with the end of the outward-facing structure 202 near the outlet end 102. This effectively reduces the angle between the flow pipe 10 and the first end cap 21 and the second end cap 22 within the flow cavity 201, optimizes the airflow path design, ensures a smooth transition of gas from the flow pipe 10 into the flow cavity 201, improves the efficiency and uniformity of gas flow, and further reduces the aerodynamic noise during compressor operation.

[0049] like Figure 4As shown, Embodiment 2 of this utility model provides an air intake component. The difference from Embodiment 1 is that the cylinder 20 includes a third end cap 23, which includes a third body 231 and a third flange 232. The third body 231 has a third through hole. The flow pipe 10 passes through the third flange 232 and is inserted into the third through hole. The third flange 232 is circumferentially disposed at the edge of the third through hole and sleeved on the outer periphery of the flow pipe 10. The extension direction of the third flange 232 is the same as the extension direction of the flow pipe 10, forming an outward-facing structure 202. A second transition structure 233 is provided between the third flange 232 and the third body 231. The second transition structure 233 protrudes towards the flow cavity 201 from the end of the third flange 232 near the air outlet 102, forming a guide portion 203. By integrating the outward-folding structure 202 and the flow guide 203 onto the third end cap 23, the assembly process is simplified, thereby improving assembly speed and product consistency, reducing assembly errors and rework, increasing production efficiency, and lowering production costs.

[0050] Furthermore, along the axial direction of the flow pipe 10, the end of the outlet 102 is flush with the end of the third flange 232 near the flow cavity 201. This avoids the angle between the end of the flow pipe 10 and the second transition structure 233, and prevents the airflow from impacting the flow pipe 10 or the second transition structure 233 at this point, thus ensuring the continuity and stability of the gas flow path.

[0051] The second transition structure 233 has a groove on the side away from the flow cavity 201, which is formed by a stamping process. The groove reduces material waste and lightens the weight of the third end cap 23. The high precision and speed of the stamping process reduce reliance on highly skilled operators, simplify the production process, and improve the consistency and quality of the intake components.
