Description

Technical Field

[0001] This utility model relates to the field of air pump technology, specifically an air pump that prevents pipes from falling off. Background Technology

[0002] An air pump is a mechanical device used to compress and transport gases. It works by drawing in air or other gases through mechanical principles, compressing them, and then discharging them, thereby creating an airflow or increasing gas pressure. During use, prolonged plugging and unplugging can easily cause the connections of an air pump to loosen.

[0003] To overcome the above-mentioned defects, a Chinese patent (publication number: CN220505404U) discloses a vortex air pump with anti-detachment technology for air tubes, belonging to the field of air pump technology. It solves the problem that the air tubes of existing vortex air pumps are prone to detachment after long-term use or repeated insertion and removal. The anti-detachment vortex air pump includes an air pump body with an air inlet and an air outlet. A quick connector is provided on the air outlet. Several snap-fit ​​grooves are opened on the side wall of the quick connector, and magnets are provided in the snap-fit ​​grooves. An external connector for connecting the air tube is provided on the quick connector. A connecting fork is provided on the side wall of the external connector. A rotation buckle is provided on the connecting fork. An elastic washer is also provided at the top of the external connector. It has the advantages of simple, quick and stable installation.

[0004] While existing technologies can overcome the shortcomings mentioned above, other problems still exist during their operation: the air pump outputs high-pressure gas through the pipeline during operation, and the pipeline connection of the air pump may loosen after long-term use or repeated plugging and unplugging. Existing air pumps generally use fasteners to reinforce the connection between the air pump and the pipeline. The instantaneous pressure generated by the air pump during operation can cause vibration at the connection, which can easily lead to loosening of the fasteners at the connection. Utility Model Content

[0005] The purpose of this utility model is to provide an air pump that prevents pipes from falling off, so as to solve the problem in the above-mentioned background technology that the instantaneous pressure generated by the air pump during operation will cause vibration at its connection, which will easily lead to the loosening of the fasteners at its connection.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an air pump for preventing pipe detachment, comprising an air pump assembly, wherein a buffer anti-detachment structure is fixedly connected to the output end of the air pump assembly;

[0007] The anti-detachment structure includes an installation tube fixedly connected to the output end of the air pump assembly, and a movable tube slidably connected inside the installation tube. A piston ring is fixedly connected to one end of the movable tube inside the installation tube, and the piston ring and the inner side of the installation tube form a sealing structure. Corrugated pipes are fixedly connected to both ends of the piston ring and both ends of the inner side of the installation tube.

[0008] Preferably, a spring is provided on the outside of the bellows, and the two ends of the spring are fixedly connected to the piston ring and the inner side of the end of the mounting tube, respectively, and a sealing structure is formed between the bellows and the movable tube.

[0009] Preferably, the end of the movable tube is equipped with a quick-connect structure, and the quick-connect structure includes a connecting sleeve fixedly connected to the outside of one end of the movable tube, and a sealing groove is formed between the inner side of the connecting sleeve and the end of the movable tube.

[0010] Preferably, the quick-connect structure further includes an outer pipe, and the end of the outer pipe is engaged with the inside of the sealing groove to form a sealing structure, and the outer side of the connecting sleeve is provided with threads.

[0011] Preferably, a drive ring is fixedly connected to one end of the outer tube near the connecting sleeve, and a threaded sleeve is slidably connected to the outer tube, and the threaded sleeve is threadedly connected to the outer side of the connecting sleeve.

[0012] Preferably, the air pump assembly includes a motor and a housing, and an exhaust pipe is provided tangentially on the outer side of the housing. A flange is slidably connected to the outer side of the mounting pipe away from the movable pipe, and a sealing ring is fixedly connected to the inner side of the flange. The mounting pipe and the exhaust pipe are connected to each other through the flange, and the sealing ring is engaged with the inside of the exhaust pipe to form a sealing structure.

[0013] Preferably, a turbine fan is fixedly connected to the output end of the motor, and the housing is fixedly connected to one side of the output end of the motor. The turbine fan is located inside the housing, and an air inlet pipe is provided in the middle of the end of the housing away from the motor.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This type of air pump with anti-detachment pipe has a bellows that absorbs high-frequency vibration energy through deformation when the air pump generates pulse pressure, and the spring assembly provides elastic restoring force to maintain the system stiffness. The connection structure attenuates impact vibration while maintaining airtightness, preventing the risk of loosening caused by resonance in traditional rigid connections.

[0016] The drive ring is forced to move towards the connecting sleeve by moving the threaded sleeve on the outside of the connecting sleeve. In turn, the drive ring is forced to exert a force towards the inside of the sealing groove at the end of the outer pipe, thereby making the connection between the drive ring and the sealing groove tighter and facilitating the disassembly and installation of the outer pipe.

[0024] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 1 - Figure 4 The present invention provides the following technical solution: an air pump for preventing pipe detachment, comprising an air pump assembly 1, wherein a buffer anti-detachment structure is fixedly connected to the output end of the air pump assembly 1; the anti-detachment structure includes an installation pipe 2 fixedly connected to the output end of the air pump assembly 1, and a movable pipe 3 is slidably connected inside the installation pipe 2, wherein a piston ring 4 is fixedly connected to one end of the movable pipe 3 located inside the installation pipe 2, and the piston ring 4 and the inner side of the installation pipe 2 form a sealing structure, wherein corrugated pipes 5 are fixedly connected to both ends of the piston ring 4 and both ends of the inner side of the installation pipe 2; a spring 6 is provided on the outside of the corrugated pipe 5, and both ends of the spring 6 are fixedly connected to the piston ring 4 and the inner side of the end of the installation pipe 2 respectively, and a sealing structure is formed between the corrugated pipe 5 and the movable pipe 3.

[0026] During the use of the air pump, the gas output by the air pump assembly 1 will be input into the external pipe 9 through the installation pipe 2. The air supply effect is achieved through the interconnection between the external pipe 9 and the air-using equipment. The air pump assembly 1 and the external pipe 9 are connected through the installation pipe 2, and the installation pipe 2 is interconnected with the external pipe 9 through the movable pipe 3.

[0027] When the internal air pressure of the mounting tube 2 changes abruptly, the impact of the gas on the components inside the mounting tube 2 will cause the mounting tube 2 to vibrate. At the same time, the movable tube 3 located inside the mounting tube 2 will slide inside the mounting tube 2. The vibration impact is effectively attenuated by the movable tube 3 during the free stroke of the mounting tube 2, preventing the joint from loosening due to stress concentration in the traditional rigid connection. This prevents the connection between the mounting tube 2 and the air pump assembly 1, as well as the connection between the movable tube 3 and the outer pipe 9, from loosening due to vibration.

[0028] During the vibration absorption process of the movable tube 3, the movable tube 3 will drive the piston ring 4 to slide inside the mounting tube 2. When the piston ring 4 slides inside the mounting tube 2, it will drive the bellows 5 to expand and contract inside to absorb mechanical vibration energy. Since a seal is formed between the mounting tube 2 and the piston ring 4, and a seal is formed between the movable tube 3 and the bellows 5, the inside of the mounting tube 2 remains airtight during the movement of the movable tube 3 and the piston ring 4 to prevent air leakage. After the movement is completed, the movable tube 3 and the piston ring 4 will be driven by the bellows 5 to return the piston ring 4 to its initial state in the middle of the mounting tube 2.

[0029] Example 2: Based on Example 1, please refer to... Figure 5 The quick-release structure was also disclosed, and its specific structure is as follows: a quick-connect structure is installed at the end of the movable tube 3, and the quick-connect structure includes a connecting sleeve 7 fixedly connected to the outside of one end of the movable tube 3, and a sealing groove 8 is formed between the inner side of the connecting sleeve 7 and the end of the movable tube 3; the quick-connect structure also includes an outer tube 9, and the end of the outer tube 9 is engaged with the inside of the sealing groove 8 to form a sealing structure, and the outer side of the connecting sleeve 7 is provided with threads; a drive ring 10 is fixedly connected to the outer side of the outer tube 9 near the connecting sleeve 7, and a threaded sleeve 11 is slidably connected to the outer side of the outer tube 9, and the threaded sleeve 11 is threadedly connected to the outer side of the connecting sleeve 7.

[0030] During the connection process between the outer tube 9 and the movable tube 3, the end of the outer tube 9 is first installed inside the sealing groove 8. At this time, the end of the outer tube 9 will form a seal with the inside of the sealing groove 8. Then, the threaded sleeve 11 on the outside of the outer tube 9 is slid until it moves to the outside of the connecting sleeve 7. Then, the threaded sleeve 11 is rotated to move outside the connecting sleeve 7, and the inside of the threaded sleeve 11 will be connected to the drive ring 10. The movement of the threaded sleeve 11 outside the connecting sleeve 7 applies a force to the drive ring 10 toward the connecting sleeve 7. In turn, the drive ring 10 applies a force to the end of the outer tube 9 toward the inside of the sealing groove 8, thereby making the connection between the drive ring 10 and the sealing groove 8 tighter and improving the airtightness of the connection.

[0031] Example 3: Based on Example 2, please refer to... Figure 6The following structure is also disclosed: the air pump assembly 1 includes a motor 14 and a housing 16, and an exhaust pipe 18 is provided in the tangential direction on the outer side of the housing 16. A flange 12 is slidably connected to the outer side of the mounting pipe 2 away from the movable pipe 3, and a sealing ring 13 is fixedly connected to the inner side of the flange 12. The mounting pipe 2 is connected to the exhaust pipe 18 through the flange 12, and the sealing ring 13 is engaged with the inside of the exhaust pipe 18 to form a sealing structure. A turbine fan 15 is fixedly connected to the output end of the motor 14, and the housing 16 is fixedly connected to one side of the output end of the motor 14. The turbine fan 15 is located inside the housing 16, and an air inlet pipe 17 is provided in the middle of the end of the housing 16 away from the motor 14.

[0032] During operation, the air pump assembly 1 first powers the motor 14 to drive the turbine fan 15 to rotate. The airflow is drawn in through the axial air inlet pipe 17 and then centrifugally pressurized to form a spiral airflow that accelerates along the inner wall of the housing 16. This causes the high-pressure gas to be smoothly output in a tangential motion state and discharged from the exhaust pipe 18, thus completing the air supply operation of the air pump assembly 1.
