[0016] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0018] like Figure 1 - Figure 4 As shown, this application provides a car air pump with uniform and rapid exhaust, including: an air pump body 1, an air inlet groove 2 fixedly connected to one side of the air pump body 1, and a storage compartment 3 formed inside the side wall of the air pump body 1; specifically, as shown... Figure 1 As shown, a protective plate 4 is rotatably connected to one end of the inner side of the storage compartment 3. A magnetic suction plate is connected to the inner side of the protective plate 4. After rotation, the storage compartment 3 can be sealed to protect the inflatable structure stored inside the storage compartment 3. A snap-fit ​​block 5 that matches the outer diameter of the converging tube 10 is fixedly connected to the bottom inner side of the storage compartment 3. The snap-fit ​​block 5 is snapped on the outside of the converging tube 10 to position the inflatable structure.

[0019] The diversion exhaust assembly includes an exhaust pipe 6, which is fixedly connected to one end of the inner side of the storage compartment 3. A diversion pipe 8 is connected to one side of the exhaust pipe 6, and an exhaust branch pipe 9 is fixedly connected to the outer side of the diversion pipe 8. The diversion exhaust assembly is used for the dispersed exhaust of airflow; specifically, such as... Figure 2 As shown, one end of the air outlet pipe 6 is fixedly connected to a threaded connector 7, and the inside of one wall of the diversion pipe 8 is rotatably connected to a connecting seat 12 that is threadedly connected to the threaded connector 7. The diversion pipe 8 and the air outlet pipe 6 are threadedly connected through the connecting seat 12 and the threaded connector 7.

[0020] Specifically, such as Figure 3 As shown, the outer wall of the connecting seat 12 is connected with an anti-slip strip 13. The anti-slip strip 13 facilitates the rotation and adjustment of the connecting seat 12. An annular guide groove 14 is provided inside one wall of the diversion pipe 8, which is rotatably connected to the connecting seat 12. The connecting seat 12 rotates and adjusts in the annular guide groove 14 inside the diversion pipe 8, which improves the convenience of fastening and installation.

[0021] Specifically, such as Figure 3 As shown, guide vanes 15 are fixedly connected to the inner wall of the split pipe 8. The cross-section of the guide vanes 15 is arc-shaped. The arrangement of the guide vanes 15 allows the airflow to be guided more smoothly to the exhaust branch pipe 9 in the split pipe 8, which further improves the exhaust efficiency.

[0022] Specifically, such as Figure 4As shown, the converging pipe 10 has an integrated guide rib 16 inside. The guide rib 16 allows the converged airflow to be guided and transmitted in a spiral pattern, dispersing the airflow and reducing airflow resistance.

[0023] The inflation replacement assembly includes a manifold 10, which is fixedly connected to one side of the exhaust branch pipe 9. A snap-fit ​​end 17 is connected to one side of the manifold 10, and an elastic corrugated pipe 19 is provided on one side of the snap-fit ​​end 17. The inflation replacement assembly is used for replacing the inflation connection structure.

[0024] Specifically, such as Figure 4 As shown, an inflation connector 11 is fixedly connected to one side of the snap-fit ​​end 17, and an elastic bellows tube 19 is fixedly connected to the inner side of the inflation connector 11. After the snap-fit ​​end 17 is inserted into the inflation connector 11, it fits tightly with the elastic bellows tube 19. A spring is connected to the outer gap of the elastic bellows tube 19 to facilitate the extension and retraction adjustment of the elastic bellows tube 19 by a certain distance.

[0025] Specifically, such as Figure 4 As shown, the inner side of the inflation connector 11 is provided with a snap-fit ​​groove 18 that rotates and snaps into the snap-fit ​​end 17. The snap-fit ​​groove 18 consists of three parts: the first part is adapted to the cross-section of the snap-fit ​​end 17, the second part is adapted to the annular cross-section of the outer snap-fit ​​block of the snap-fit ​​end 17, and the third part is half of the outer snap-fit ​​block of the snap-fit ​​end 17, and forms a 90-degree angle with the first part of the groove of the snap-fit ​​end 17. This makes it easy for the snap-fit ​​end 17 to rotate 90 degrees after being inserted into the inflation connector 11, and then, with the elastic compression of the elastic bellows 19, to achieve the positioning effect.

[0026] In this embodiment: a diversion pipe 8 is set to connect to the exhaust branch pipe 9 to form a diversion exhaust device, which disperses the centralized exhaust into multiple directions, effectively reducing exhaust noise and vibration and improving exhaust uniformity. The setting of the guide plate 15 allows the airflow to be transmitted more smoothly to the exhaust branch pipe 9 in the diversion pipe 8, reducing airflow resistance and improving exhaust efficiency. The outlets of the exhaust branch pipes 9 are staggered to avoid mutual interference of airflow, making the exhaust more stable. The inner side of the inflation connector 11 is connected to the snap-fit ​​end 17 through the snap-fit ​​groove 18, and a rotatable and detachable connection structure is set to facilitate the convenient installation and replacement of the inflation connector 11 that is blocked by dust or damaged.

[0027] Specifically, during the use of the car air pump, gas is first transferred through the air pump inside the pump body 1. The external airflow is filtered through the air inlet slot 2 and then compressed through the pump body 1 before being discharged from the outlet pipe 6. The airflow then enters the diversion pipe 8 through the outlet pipe 6. Guided by the guide vane 15, the airflow is evenly distributed within the diversion pipe 8 and enters multiple exhaust branch pipes 9. Since the outlets of each exhaust branch pipe 9 are staggered, the airflow is dispersed, avoiding noise and vibration problems caused by concentrated exhaust and improving the uniformity of inflation. The diversion pipe 8 and the outlet pipe 6 are connected by a threaded joint 7 and a connecting seat 12, facilitating disassembly and maintenance. The inner side of the inflation connector 11 is engaged with the locking end 17 and the locking groove 18 by rotation, allowing for easy replacement in case of damage or blockage, thus improving the maintenance efficiency of the device.
