[0008] By adopting the above technical solution, when vacuuming objects such as compression bags that need to be vacuumed, the air valve is embedded in the air valve slot, and the compression bag can be vacuumed by pressing the momentary switch. The gas enters the middle cavity through the vent, and then the air inlet pipe of the micro air pump is manually driven to extract the air in the middle cavity. Among them, the sealing rubber cap contacts external objects, which plays a buffering role on the one hand and a sealing role on the other hand, thereby improving the efficiency of vacuuming. When it is necessary to inflate, the micro air pump can be automatically driven to inflate by pressing the self-locking switch, and the air outlet pipe of the micro air pump is automatically driven to output gas to the middle cavity, and then the air is discharged through the vent, so that the vacuum rod can play both the role of vacuuming and the role of inflation, thereby improving its practicality.

[0030] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0031] A vacuum rod, such as Figure 1 、 Figure 3 and Figure 5 As shown, it includes a shell 1, a front end cover 2 and a tail end cover 3. An integrated frame 17 is fixed in the shell 1 by screws. A battery frame 18 and an air pump frame 19 are respectively provided on both sides of the integrated frame 17. An automatically driven micro air pump 8 and a manually driven micro air pump 9 are provided in the shell 1. The air pump frame 19 is used to fix the automatically driven micro air pump 8. Specifically, the air pump frame 19 includes two claws symmetrically arranged on both sides of the integrated frame 17. The claws are used to clamp the outer wall of the manually driven micro air pump 9. The battery frame 18 is used to place batteries. A self-locking switch 10 for starting and closing the automatically driven micro air pump 8 is provided on the shell 1. A moment switch 11 for starting and closing the manually driven micro air pump 9 is provided on the tail end cover 3. The moment switch 11 is reset by a compression spring.

[0032] like Figure 1 、 Figure 3 and Figure 5 As shown, the shell 1 includes a symmetrically arranged cover shell 1 28 and a cover shell 2 29, and the two sides of the cover shell 1 28 and the cover shell 2 29 are in conflict with each other. The inner edges of the two sides of the cover shell 1 28 are integrally formed with a plurality of snap-in blocks. Conversely, the two sides of the cover shell 2 29 are integrally formed with a plurality of snap-in block receiving seats for accommodating the snap-in blocks. The cover shell 1 28 and the cover shell 2 29 are fixed by embedding the snap-in blocks into the snap-in block receiving seats. The inner edges of the cover shell 1 28 and the cover shell 2 29 are respectively facing the battery rack 18 and the air pump rack 19, and the self-locking switch 10 is located on the cover shell 2 29. When the cover shell 1 28 and the cover shell 2 29 are combined, circular convex edges are formed at both ends of the shell 1, and the circular convex edges are used to embed the inner edges of the front cover 2 or the tail cover 3, thereby further preventing the cover shell 1 28 and the cover shell 2 29 from separating through the front cover 2 and the tail cover 3.

[0033] like Figure 3 and Figure 4 As shown, a plurality of card blocks 24 distributed in a ring array are integrally formed on the outer edge of one end of the shell 1, and a plurality of quick-release card slots 25 distributed in a ring array and arranged in an L shape are opened on the inner edge of the front end cover 2. One end of the quick-release card slot 25 is connected to the end face of the front end cover 2 and is used to accommodate the card block 24 for embedding.

[0034] like Figure 2 、 Figure 3 and Figure 4As shown, a partition 5 is provided between the front end cover 2 and the shell 1, and an intermediate cavity 6 is formed between the front end cover 2 and the partition 5. The outlet pipe of the automatically driven micro air pump 8 and the air inlet pipe of the manually driven micro air pump 9 are both connected to the intermediate cavity 6. Specifically, the partition 5 is integrally formed with a mounting tube 16 which is connected to both sides of the partition 5 and accommodates the embedded air inlet pipe of the automatically driven micro air pump 8. The inner edge of the mounting tube 16 is pressed against the outer wall of the air inlet pipe of the automatically driven micro air pump 8. The partition 5 is integrally formed with a connecting tube 20 which is arranged toward the middle of the shell 1 and connected to the intermediate cavity 6. The air inlet pipe of the manually driven micro air pump 9 and the connecting tube 20 are connected by a rubber hose 21. An annular groove 22 is provided on the outer wall of the partition 5. A sealing ring 23 is provided in the annular groove 22 which is pressed against the inner edge of the front end cover 2. The sealing ring 23 is made of rubber.

[0035] like Figure 1 and Figure 2 As shown, the front end cover 2 is provided with an air valve slot 4 that matches the air valve, and the air valve slot 4 includes a large circular groove 12 and a small circular groove 13. The small circular groove 13 is located in the center of the bottom of the large circular groove 12. The large circular groove 12 and the small circular groove 13 are respectively used to accommodate the main body of the compression bag air valve and the circular protrusion in the center of the compression bag air valve. The front end cover 2 is provided with a vent hole 7 connected to the middle cavity 6. The bottom of the large circular groove 12 is fixedly connected to an external pipe port 14 extending toward the middle cavity 6. The vent hole 7 is located in the external pipe port 14. The inner edge of the vent hole 7 is set in a frustum shape, and its large end is set outward for embedding external hoses of different diameters. The bottom of the large circular groove 12 is provided with a connecting groove 15 connecting the vent hole 7 and the small circular groove 13.

[0036] like Figure 1 、 Figure 3 and Figure 4 As shown, a sealing rubber cap 30 is detachably connected to the front end cover 2. The sealing rubber cap 30 and the front end cover 2 are detachably connected via a groove and protrusion structure. The sealing rubber cap 30 is made of rubber.

[0037] like Figure 3 and Figure 5 As shown, one end of the cover shell 29 is integrally formed with two snap hooks 26 with elastic recovery ability, and the snap hook 26 includes a connecting plate and a guide block. The connecting plate fixes the guide block and the cover shell 29, and the tail end cover 3 is provided with two quick-release card slots 27 for accommodating the embedding of the snap hook 26. The two guide blocks are provided with guide surfaces on the sides facing each other, and the distance between the two guide surfaces gradually decreases from the side close to the cover shell 29 to the other side. When the guide block is embedded in the quick-release card slot 27, the guide surface is used to resist the inner edge of the quick-release card slot 27, generating a component force that makes the two guide blocks approach each other, and the connecting plate is deformed to make the guide block pass through the quick-release card slot 27, and then the connecting plate is deformed and restored to make the guide block resist the tail end cover 3 to achieve fixation with the cover shell 29 and the tail end cover 3.

[0038] Working principle: When deflating objects such as compression bags that need to be deflated, the air valve is embedded in the air valve slot 4. The large circular groove 12 and the small circular groove 13 are set to match the main body of the compression bag air valve and the convex part in the middle, so that the compression bag air valve can cooperate with the air valve slot 4. When the vent 7 is inlet, the gas in the compression bag flows from the small circular groove 13 through the connecting groove 15 and enters the external pipe port 14, thereby not affecting the deflating of the suction rod. The compression bag can be deflated by pressing the inching switch 11, and the external hose can be inserted into the external pipe port 14 to allow the air to flow out through the external pipe port 14. The connected hose is used for suction, which improves the practicality of the suction rod and enables it to adapt to more items. The gas enters the middle cavity 6 through the vent hole 7, and the sealing ring 23 can be pre-fixed through the annular groove 22. The inner edge of the front end cover 2 is squeezed by the sealing ring 23, thereby improving the sealing between the partition 5 and the front end cover 2, and improving the suction and inflation efficiency of the vacuum pump. Then, the air inlet pipe of the micro vacuum pump 9 is manually driven to extract the air in the middle cavity 6. Among them, the sealing rubber cap 30 resists external objects, which plays a buffering role on the one hand and a sealing role on the other hand, thereby improving the efficiency of suction.

[0039] When it is necessary to inflate, by pressing the self-locking switch 10, the micro air pump 8 can be automatically driven to inflate, and the outlet pipe of the micro air pump 8 can be automatically driven to output gas into the middle cavity 6, and then the gas is discharged through the vent 7, so that the vacuum rod can play the role of both vacuuming and inflating, thereby improving its practicality. When the vacuum rod inflates, the external hose is embedded in the external pipe port 14, so that the middle cavity 6 is connected to the external hose through the vent 7, thereby facilitating inflation and being adaptable to more items that need to be inflated.

[0040] The battery rack 18 is provided to replace the battery for starting the automatically driven micro air pump 8 and the manually driven micro air pump 9. The battery is easy to carry, so that the air pump can be used anywhere, thereby improving its versatility. By embedding the card block 24 into the quick-release card slot 1 25 and rotating the shell 1 and the front end cover 2 relative to each other, the shell 1 can be fixed on the front end cover 2, which has the characteristic of easy disassembly and assembly. By engaging the buckle 26 with the quick-release card slot 2 27, it also has the characteristic of easy disassembly and assembly, thereby facilitating the molding of the air pump and improving the production efficiency of the air pump. When replacing the battery, after separating the front end cover 2 and the tail end cover 3 from the shell 1, force can be applied to separate the cover 1 28 and the cover 2 29. By disassembling the cover 1 28, the battery rack 18 can be exposed, thereby facilitating the replacement of the used battery, making it more convenient to replace the battery of the air pump. The self-locking switch 10 is located on the cover 2 29, so that the battery replacement does not affect the self-locking switch 10.

[0041] By pressing the inner edge of the mounting tube 16 against the air inlet pipe of the automatic-driven micro air pump 8, the partition 5 is fixed to the automatic-driven micro air pump 8, thereby improving the fixing strength of the automatic-driven micro air pump 8. The air pump frame 19 facilitates the fixation of the automatic-driven micro air pump 8. The setting of the integrated frame 17 can improve the firmness of the internal components of the vacuum rod and improve the integrity of the vacuum rod. The connecting tube 20 and the air inlet pipe of the manually-driven micro air pump 9 are connected by the hose 21, thereby lengthening the distance between the manually-driven micro air pump 9 and the partition 5, so that the installation of the air pipes of the manually-driven micro air pump 9 and the automatic-driven micro air pump will not interfere with each other, which can make the layout inside the shell 1 more reasonable, conveniently reduce the volume of the vacuum rod, and facilitate carrying.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention.
