DETAILED DESCRIPTION

[0027] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1-Figure 7 The pump body 100 according to the embodiment of the present invention includes: a housing 10 and a plurality of piston assemblies 20 .

[0028] Specifically, if Figure 1-Figure 7 As shown, the shell 10 is formed with a first installation cavity 11 and a plurality of second installation cavities 12. The first installation cavity 11 is arranged in the central area of ​​the shell 10, and the plurality of second installation cavities 12 are arranged at intervals along the outer peripheral side of the shell 10, and the plurality of second installation cavities 12 are connected to the first installation cavity 11; a plurality of piston assemblies 20 are respectively arranged in the plurality of second installation cavities 12, and the piston assemblies 20 include cylinder sleeves 21, which are arranged in corresponding second installation cavities 12, and the cylinder sleeves 21 and the shell 10 are integrally formed parts.

[0029] Combination Figure 1-Figure 7 The housing 10 is the basic component of the entire pump body 100, which forms the working space of the pump. The first installation cavity 11 is formed in the central area of ​​the housing 10, and a plurality of second installation cavities 12 are arranged at intervals along the circumference of the first installation cavity 11. The plurality of second installation cavities 12 are connected to the first installation cavity 11 to facilitate the flow of fluid in the cavity. A piston assembly 20 is arranged in the second installation cavity 12, and the cylinder sleeve 21 of the piston assembly 20 is integrally formed with the housing 10, that is, the cylinder body and the housing 10 are manufactured as a whole during the manufacturing process, rather than being made of separate components.

[0030] According to the pump body 100 of the embodiment of the present invention, the cylinder sleeve 21 and the housing 10 are integrally formed, which can reduce the assembly cost of the pump body 100, effectively enhance the overall structural strength of the pump body 100, reduce the risk of wear and loosening caused by long-term operation, improve the durability of the pump body 100, reduce the failure rate of the pump body 100, and thus extend the service life of the pump body 100. The design of the cylinder sleeve 21 and the housing 10 being integrally formed reduces seams and connections, thereby reducing the possibility of fluid leakage and improving the sealing performance of the pump. The reasonable layout of the first installation cavity 11 and the second installation cavity 12 can optimize the flow path of the fluid inside the pump body 100, reduce unnecessary resistance losses, and improve pumping efficiency.

[0031] According to some embodiments of the present invention, Figure 1-Figure 5 As shown, the shell 10 is formed with an air intake channel 13, and the air intake channel 13 is connected to the first installation cavity 11. The air intake channel 13 includes: a first air intake channel 131 and a second air intake channel 132. One end of the first air intake channel 131 is connected to one end of the second air intake channel 132. The other end of the first air intake channel 131 is suitable for connecting with an external air source along the axial direction of the shell 10, and the other end of the second air intake channel 132 along the radial direction of the shell 10 is connected to the first installation cavity 11. An angle is formed between the first air intake channel 131 and the second air intake channel 132.

[0032] The air inlet channel 13 is a channel in the pump body 100 for introducing external gas into the pump body 100, and is composed of a first air inlet channel 131 and a second air inlet channel 132. The first air inlet channel 131 extends along the axial direction of the housing 10 and is respectively connected with the second air inlet channel 132 and an external source, ensuring that the external airflow smoothly enters the housing 10. The second air inlet channel 132 extends along the radial direction of the housing 10, and the second air inlet channel 132 is respectively connected with the first air inlet channel 131 and the first installation cavity 11, so that the gas passes through the first air inlet channel 131 and allows the intake air to enter the first installation cavity 11. The angle formed between the first air inlet channel 131 and the second air inlet channel 132 can optimize the direction conversion of the airflow, ensuring that the gas smoothly enters the pump body 100 from the outside and is guided to the first installation cavity 11.

[0033] Thus, the first air inlet channel 131 facilitates the gas to smoothly enter the first installation cavity 11, which can better drive the piston assembly 20 to move and enhance the overall performance of the pump body 100. An angle between the first air inlet channel 131 and the second air inlet channel 132 can form an optimized airflow path to reduce the occurrence of turbulence and vortex, reduce the resistance of the airflow when turning, and improve the smoothness of the gas flow, thereby improving the working efficiency of the pump body 100, reducing energy consumption, and improving the energy efficiency ratio of the pump.

[0034] According to some embodiments of the present invention, Figure 5As shown, the included angle between the first air intake channel 131 and the second air intake channel 132 is α, and α satisfies: 0<α<180°.

[0035] If α=0° or α=180°, the first air inlet channel 131 and the second air inlet channel 132 are arranged in a straight line. In this case, the change in the direction of the gas flow is small, which may cause the gas flow to be relatively straight, but at the same time, the local resistance may also be increased due to the small angle. Preferably, when α is in the range of 45° to 90°, the change in the direction of the gas flow and the smoothness can be better balanced, allowing the gas to change direction without generating too much turbulence.

[0036] Thus, limiting the range of the angle between the first air inlet channel 131 and the second air inlet channel 132 can help optimize the fluid mechanics performance, help the gas to smoothly enter the first installation cavity 11, thereby better coordinating the action of the piston assembly 20, reducing energy loss during the gas flow process, and improving the efficiency of the pump body 100. By limiting the range of α, the generation of turbulence can be effectively reduced, thereby reducing the noise level generated when the pump body 100 is running, and improving the overall performance of the pump body 100.

[0037] According to some embodiments of the present invention, Figure 6 As shown, the housing 10 is formed with a connecting channel 14 , which extends along the circumference of the housing 10 , and connects two adjacent second mounting cavities 12 .

[0038] The main function of the connecting channel 14 is to connect two adjacent second installation chambers 12 so that fluid or gas can flow between these installation chambers. The connecting channel is formed as an annular gas path. By connecting the adjacent second installation chambers 12, the connecting channel 14 can help achieve uniform distribution of fluid or gas in the entire pump body 100, thereby improving the working efficiency of the pump. The existence of the connecting channel 14 makes the cooperation between the piston assemblies 20 closer, can better synchronize the actions of each piston, and enhance the overall performance of the pump body 100.

[0039] Thus, the communicating channel can reduce the pressure fluctuation caused by the asynchronous piston action by connecting the adjacent second installation chambers 12, so that the pump body 100 can run more smoothly. The annular gas path setting facilitates uniform fluid distribution and synchronous piston action, helps to reduce the wear of the internal components of the pump body 100, and improves the reliability and service life of the pump body 100.

[0040] According to some embodiments of the present invention, Figure 4 As shown, the shell 10 is formed with an air outlet channel 15, which is spaced apart from the air inlet channel 13. One end of the air outlet channel 15 is connected to the communication channel, and the other end of the air outlet channel 15 is connected to the outside of the shell 10 along the axial direction of the shell 10.

[0041] The air outlet channel 15 is arranged inside the housing 10, and is spaced apart from the air inlet channel 13 to avoid mutual interference. One end of the air outlet channel 15 is connected to the connecting channel 14, and the other end is connected to the outside of the housing 10 along the axial direction of the housing 10, so as to ensure that the gas can be discharged smoothly. External gas enters the first installation cavity 11 through the first air inlet channel 131 and the second air inlet channel 132. The gas is transmitted to each second installation cavity 12 through the connecting channel 14 to drive the piston assembly 20 to work. The processed gas is collected in the air outlet channel 15 through the connecting channel 14, and finally discharged into the external environment along the axial direction of the housing 10.

[0042] Thus, the outlet channel 15 is spaced from the inlet channel 13, avoiding direct interference between the intake and exhaust, ensuring smooth flow of gas inside the pump body 100, and improving the safety and stability of the operation of the pump body 100. The separate inlet channel 13 and outlet channel 15 design reduces the risk of gas backflow and enhances the safety of the operation of the pump body 100.

[0043] According to some embodiments of the present invention, Figure 6 and Figure 7 As shown, the piston assembly 20 also includes: a cylinder body and a cylinder cover 22, the cylinder body and the second installation cavity 12 can be movably matched; the cylinder cover 22 is arranged at one end of the second installation cavity 12 away from the first installation cavity 11, and the cylinder cover 22 cooperates with the cylinder sleeve 21 to seal the cylinder body.

[0044] The cylinder body is the part where the piston moves. It can be movably matched with the second installation cavity 12, that is, the cylinder body can move back and forth in the second installation cavity 12 to complete the process of sucking and discharging the fluid. The cylinder cover 22 is arranged at one end of the second installation cavity 12 away from the first installation cavity 11. The cylinder cover 22 is used in conjunction with the cylinder sleeve 21 to seal the cylinder body to ensure that the fluid does not leak from the gap between the cylinder body and the second installation cavity 12 during the movement of the piston. The cylinder sleeve 21 is arranged in the second installation cavity 12 and is an integrally formed part with the housing 10. The cylinder sleeve 21 cooperates with the cylinder body to provide the closed space required for the piston movement, and completes the sealing function together with the cylinder cover 22.

[0045] Thus, the close fit between the cylinder cover 22 and the cylinder sleeve 21 can effectively seal the cylinder body, prevent fluid leakage, and improve the working efficiency of the pump body 100. The movable fit design between the cylinder body and the second mounting cavity 12 makes the piston move more smoothly and reduces wear caused by vibration or friction.

[0046] According to some embodiments of the present invention, Figure 7 As shown, a first step portion 23 is formed at one end of the cylinder sleeve 21 away from the first installation cavity 11 . The first step portion 23 is arranged on the outer peripheral side of the cylinder sleeve 21 , and the cylinder cover 22 cooperates with the first step portion 23 .

[0047] The first step portion 23 extends along the circumference of the cylinder liner 21, and the cross-sectional area along the first step portion 23 is larger than the cross-sectional area of ​​one end of the cylinder liner 21 adjacent to the cylinder head 22. The first step portion 23 is used to cooperate with the cylinder head 22 to ensure that the cylinder head 22 is correctly installed and forms a tight seal with the cylinder liner 21. The cooperation between the first step portion 23 and the cylinder head 22 can provide a reliable positioning reference, so that the cylinder head 22 can be accurately aligned during installation, thereby ensuring the sealing between the cylinder body and the cylinder head 22.

[0048] Thus, through the design of the first step portion 23, the cylinder head 22 can be more firmly fixed on the cylinder sleeve 21, and the fit between the cylinder head 22 and the cylinder sleeve 21 of the piston assembly 20 becomes tighter and more reliable, reducing looseness caused by vibration or improper operation, and improving the stability of the piston assembly 20. The design of the first step portion 23 makes the installation of the cylinder head 22 simple and intuitive, reduces the difficulty of assembly, and facilitates rapid positioning and disassembly during disassembly and maintenance.

[0049] According to some embodiments of the present invention, Figure 2 As shown, the first installation cavity 11 is formed with a first opening 111 along the axial direction of the housing 10 , and the pump body 100 includes: a first cover body 24 , the first cover body 24 cooperates with the first opening 111 , and the first cover body 24 and the first opening 111 are riveted structures.

[0050] The first installation cavity 11 is formed with a first opening 111 along the axial direction of the housing 10, and the first opening 111 is used to connect the first cover 24 to close the first installation cavity 11. The riveting structure realizes connection by deforming a metal rivet (or a similar device), which can provide a very high connection strength and is suitable for applications that need to withstand greater stress. The riveted connection parts are not easy to loosen due to vibration, and the riveted connection usually has a long service life and can withstand repeated use without failure.

[0051] Thus, the first cover 24 is fixed at the first opening 111 by the riveting structure to ensure close contact between the first cover 24 and the housing 10, so as to ensure good sealing of the first installation cavity 11 and prevent leakage of fluid or gas. The riveting structure not only provides a firm connection, but also enhances the overall structural stability of the pump body 100 and reduces vibration and looseness caused by the action of the piston. The use of the riveting structure makes the assembly of the first cover 24 relatively simple and reduces the assembly cost of the pump body 100.

[0052] According to some embodiments of the present invention, Figure 7As shown, the shell 10 is formed with a first sealing groove 16, and the first sealing groove 16 is axially arranged on one side of the shell 10 adjacent to the first cover body 24, and the first sealing groove 16 is arranged on the outer peripheral side of the first opening 111, and the first sealing groove 16 extends along the circumference of the shell 10, and the first sealing groove 16 is suitable for cooperating with the controller shell 10.

[0053] The first sealing groove 16 extends along the circumference of the shell 10. The first sealing groove 16 is arranged on the outer peripheral side of the first opening 111. A sealing member may be arranged in the first sealing groove 16. The first sealing groove 16 is used to cooperate with the controller shell 10 to provide additional sealing performance to prevent fluid or gas leakage.

[0054] Therefore, a seal can be provided in the first sealing groove 16 to facilitate the cooperation between the housing 10 and the controller housing 10, ensure the sealing at the first opening 111, and ensure that the fluid or gas does not leak from the connection part.

[0055] According to some embodiments of the present invention, Figure 2 As shown, the plurality of second installation cavities 12 are each formed with a second opening 121 , and the pump body 100 further includes: a plurality of second covers 25 , the plurality of second covers 25 are respectively matched with the plurality of second openings 121 , and the second covers 25 and the second openings 121 are riveted structures.

[0056] The plurality of second installation cavities 12 are each formed with a second opening 121, and the second opening 121 is provided at one end of the second installation cavity 12 away from the first installation cavity 11. The second opening 121 is used to connect the second cover 25 to close the second installation cavity 12. The pump body 100 includes a plurality of second cover 25, and each second cover 25 is matched with a corresponding second opening 121. The second cover 25 and the second opening 121 are connected by a riveting structure to ensure the firmness and sealing of the connection.

[0057] Thus, the second cover 25 is fixed at the second opening 121 by the riveting structure to ensure close contact between the second cover 25 and the housing 10, so as to ensure good sealing of the second installation cavity 12 and prevent leakage of fluid or gas. The riveting structure not only provides a firm connection, but also enhances the overall structural stability of the pump body 100 and reduces vibration and looseness caused by the action of the piston. The use of the riveting structure makes the assembly of the second cover 25 relatively simple and reduces the assembly cost of the pump body 100.

[0058] According to some embodiments of the present invention, Figure 7 As shown, the second opening 121 is formed with a second step portion 122 , the second step portion 122 is disposed on a side wall of the second opening 121 , and the second cover 25 cooperates with the second step portion 122 .

[0059] The second step portion 122 extends along the circumference of the second opening 121, and is used to cooperate with the second cover 25 to ensure that the second cover 25 is correctly installed and forms a tight seal with the second opening 121. The cooperation between the second step portion 122 and the second cover 25 can provide a reliable positioning reference, so that the second cover 25 can be accurately aligned during installation, thereby ensuring the sealing between the second cover 25 and the second opening 121.

[0060] Thus, through the design of the second step portion 122, the second cover 25 can be more firmly fixed on the second opening 121, and the fit between the second cover 25 and the second opening 121 becomes tighter and more reliable, reducing looseness caused by vibration or improper operation, and improving the stability of the pump body 100. The design of the second step portion 122 makes the installation of the second cover 25 simple and intuitive, reduces the difficulty of assembly, and facilitates rapid positioning and disassembly during disassembly and maintenance.

[0061] According to some embodiments of the present invention, Figure 7 As shown, the housing 10 is formed with a second sealing groove 17, which is axially arranged on a side of the housing 10 away from the first cover body 24, and is arranged on the outer peripheral side of the first opening 111. The second sealing groove 17 extends along the circumference of the housing 10, and the second sealing groove 17 is suitable for cooperating with the motor housing 10.

[0062] The second sealing groove 17 extends along the circumference of the housing 10 and is arranged on the outer peripheral side of the first opening 111. A sealing member may be provided in the first sealing groove 16. The second sealing groove 17 is used to cooperate with the motor housing 10 to provide additional sealing performance to prevent fluid or gas leakage.

[0063] Thus, the design of the second sealing groove 17 enables a sealing member to be provided at the first opening 111, further enhancing the sealing performance between the pump body 100 and the motor housing 10, ensuring that fluid or gas does not leak from the connection portion. The cooperation between the second sealing groove 17 and the motor housing 10 can ensure the reliability of the connection portion during long-term operation, reducing leakage problems caused by loose connection or aging.

[0064] According to some embodiments of the present invention, Figure 4 As shown, the housing 10 is further formed with: a sensor fixing hole 18 , which is arranged on the inner side of the first sealing groove 16 along the radial direction of the housing 10 .

[0065] The sensor fixing hole 18 is used to install the sensor, ensuring that the sensor can be firmly fixed on the housing 10 and is convenient for connection and maintenance. The radially arranged sensor fixing holes 18 can ensure that the installation position of the sensor is stable and reliable, and is not affected by the vibration of the pump body 100 during operation. The design of the sensor fixing holes 18 enables the sensor to accurately monitor the internal state of the pump body 100, such as key parameters such as pressure and temperature, thereby improving the monitoring accuracy of the pump body 100. The radially arranged sensor fixing holes 18 make the installation and removal of the sensor more convenient, which is conducive to daily maintenance and overhaul.

[0066] Therefore, the sensor fixing hole 18 is disposed inside the first sealing groove 16 , which will not affect the sealing performance between the first sealing groove 16 and the motor housing 10 , thereby ensuring that the sealing performance of the pump body 100 is not affected.

[0067] According to some embodiments of the present invention, Figure 4 As shown, the housing 10 is formed with: a motor connector through hole 19 , and the motor connector through hole 19 is arranged on the housing 10 between two adjacent piston assemblies 20 .

[0068] The motor connector via 19 is used to pass the cable or wire of the motor connector to ensure the reliability and convenience of the electrical connection. The design of the motor connector via 19 can ensure that the cable or wire of the motor connector can safely pass through the housing 10, avoiding electrical connection problems caused by cable bending or squeezing. The motor connector via 19 is arranged on the housing 10 between two adjacent piston assemblies 20, which can make full use of the space while reducing interference with the piston assembly 20. The design of the motor connector via 19 makes the cable wiring more concise, which is convenient for installation and subsequent maintenance.

[0069] Therefore, by providing the motor connector through hole 19 , the cable of the motor connector can be protected from the influence of the external environment, the protection level of the pump body 100 is improved, the reliability of the electrical connection is ensured, and the overall structural stability of the pump body 100 is enhanced.

[0070] According to some embodiments of the present invention, Figure 1 As shown, the housing 10 is an integral forged structure.

[0071] The design of the one-piece forged structural parts makes the shell 10 have higher strength and reliability, and reduces potential defects caused by welding or splicing. The one-piece forged structural parts have no welds or splicing gaps, so the overall strength is higher, reducing stress concentration and potential cracking problems caused by welding. The surface of the one-piece molded shell 10 is smoother, reducing the unevenness caused by welding or splicing, and improving the sealing performance inside the shell 10. The manufacturing process of the one-piece forged structural parts is relatively simplified, reducing the assembly links and improving production efficiency. The one-piece forged structural parts are not prone to cracks or corrosion during long-term use, which improves the durability and service life of the pump body 100. The one-piece forging process can achieve a more complex structural design, so that the pump body 100 can better meet various functional requirements.
