Technical Field

[0001] This utility model relates to the field of portable air gun technology, and more specifically, to a container air bag lithium battery air gun. Background Technology

[0002] The container inflatable bag inflator is an integrated inflation device powered by a lithium battery. Breaking away from the limitations of traditional manual or fixed-power inflators, it can quickly inflate container inflatable bags. Users simply connect the inflator to the nozzle, select the appropriate inflation mode, and start with a single button to automatically complete the inflation. It is convenient, efficient, compact, lightweight, and easy to carry.

[0003] The current container inflatable bag inflation guns mainly have the following pain points:

[0004] 1. Battery life bottleneck: Traditional integrated lithium battery air guns use built-in non-replaceable batteries. When the battery ages or there is an emergency power shortage outdoors, the device will fail directly.

[0005] 2. Poor interface compatibility: The inflation head is fixedly connected to the gun body, making it impossible to quickly change the gun head according to the interface type of the inflation bag, resulting in the need to carry multiple devices;

[0006] 3. Bulky structure: The metal body design causes fatigue for female users.

[0007] 4. High maintenance costs: The entire battery or gas circuit components need to be repaired when damaged;

[0008] Therefore, a container air bag lithium battery inflation gun is proposed to address the above problems. Utility Model Content

[0011] The gun body has an air intake at the rear and an air inlet at the front. The air inlet has a screw-in groove on its edge and a guide plate inside.

[0012] The gun head consists of a connecting post and an inflation head. The connecting post has a screw-in protrusion at its tail end that matches the screw-in groove, and a screw-in connection at its front end to the inflation head, forming a gas channel inside. The inflation head has a plug-in part at its front end.

[0013] The base is fixed to the bottom of the gun handle, and its lower surface is provided with a plug groove;

[0014] The battery block has an interface on the top that matches the insertion slot, fixing buckles on both sides, and a detachable plate at the bottom. A battery is installed inside the battery block.

[0015] The battery block is inserted into the base via a connector and locked to both sides of the base by screws passing through the fixing buckle.

[0016] Preferably, the detachable plate is connected to the battery block by a buckle, and a battery limiting structure is provided on the inner side.

[0017] Preferably, the guide plate has a parallel structure, and its axis coincides with the gas channel.

[0018] Preferably, the insertion part is an annular slot with anti-slip texture on the surface.

[0019] Preferably, the inflation head is made of metal with a wall thickness of 0.8-1.2mm; the gun body, base and battery block are made of engineering plastic with a wall thickness of 2-3mm; and the overall weight is ≤500g.

[0020] Preferably, the gun handle is covered with an anti-slip rubber sleeve, and the surface of the sleeve has an arc-shaped groove for an embedded switch.

[0021] The technical effects and advantages of this utility model are as follows:

[0022] This invention achieves rapid power supply replacement through a modular battery block and base insertion and locking structure, solving the problem of power interruption caused by the non-replaceable batteries in traditional inflation devices. The quick-release design of the nozzle, with its screw-in groove and screw-in protrusion, supports rotational switching and can be adapted to various inflation interfaces, overcoming interface compatibility limitations. The composite lightweight structure of the metal inflation head (0.8-1.2mm thin wall) and the engineering plastic body (2-3mm thick wall) reduces the overall weight to below 500g.

[0030] 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.

[0031] Example 1

[0032] As attached Figure 1-6 The container air bag lithium battery inflation gun shown includes:

[0033] The gun body 1 has an air intake 11 at the rear and an air inlet 12 at the front. The edge of the air inlet 12 has a screw-in groove 121 and a guide plate 122 inside.

[0034] The gun head 2 consists of a connecting post 21 and an inflation head 22. The tail end of the connecting post 21 is provided with a screw-in protrusion 211 that matches the screw-in groove 121, and the front end is threaded to the inflation head 22, forming a gas channel inside. The front end of the inflation head 22 is provided with a plug-in part 221.

[0035] The base 3 is fixed to the bottom of the handle of the gun body 1, and its lower surface is provided with a plug groove.

[0036] Battery block 4 has a plug interface 41 at the top that matches the plug slot, fixing buckles 42 on both sides, and a detachable plate 43 at the bottom. A rechargeable lithium battery is installed inside the battery block 4.

[0037] The battery block 4 is inserted into the base 3 via the connector 41 and locked to both sides of the base 3 by screws through the fixing buckles 42. When installing the battery block 4, the top connector 41 is vertically inserted into the connector slot of the base 3, so that the fixing buckles 42 fit against both sides of the base, and the screws through the fixing buckles 42 complete the double locking. When assembling the gun head 2, the screw-on protrusion 211 at the end of the connecting post 21 is aligned with the screw-on groove 121 on the edge of the air inlet 12, and rotated until it "clicks" to lock. The lithium battery is built into the cavity of the battery block 4 and conducts the circuit through the connector 41. When inflating, the switch 14 is pressed, and the gas is drawn in from the air inlet 11, rectified by the guide plate 122, and output through the gas channel of the gun head 2.

[0038] In this embodiment, the detachable plate 43 is connected to the battery block 4 by a buckle, and a battery limiting structure is provided on the inner side. Furthermore, when replacing the lithium battery, the buckles on both sides of the detachable plate 43 are released by pressing the thumb; the detachable plate 43 is removed downwards to expose the battery compartment; the old battery is taken out from the battery limiting structure; the new lithium battery is inserted into the limiting groove; the lithium battery is aligned with the buckle position at the bottom of the battery block 4 and the detachable plate 43 is reinstalled. A "click" sound indicates that the process is complete.

[0039] In this embodiment, the guide plate 122 has a parallel structure, and its axis coincides with the gas channel. Furthermore, when the guide plate 122 is working, the inhaled gas impacts the parallel plate surface of the guide plate, forcing the airflow to converge along the axial direction.

[0040] In this embodiment, the plug-in part 221 is an annular slot with anti-slip texture on the surface. Furthermore, when connecting the air bag, the annular plug-in part 221 at the front end of the inflation head 22 is aligned with the air bag interface and inserted vertically. The anti-slip texture and the rubber interface produce an interference fit of 0.3-0.5mm, forming a circumferential seal. When removing, an axial pulling force of >10N can be applied to separate them. The interface surface is unworn and adaptable to 8 types of interfaces such as air beds / boats.

[0041] In this embodiment, the inflation head 22 is made of metal with a wall thickness of 0.8-1.2mm; the gun body 1, base 3, and battery block 4 are made of engineering plastic with a wall thickness of 2-3mm; the overall weight is ≤500g. Furthermore, the metal inflation head 22 is formed by spinning process, and the wall thickness is controlled to be 1.0±0.2mm; the gun body 1, base 3, and battery block 4 are injection molded with PA66 engineering plastic with a wall thickness of 2.5mm and internal reinforcing ribs; after the whole machine is assembled, the weight is calibrated to the range of 480-500g, which can be held by female users with one hand.

[0042] In this embodiment, the palm fits into the arc-shaped groove of the anti-slip rubber sleeve 13, and the thumb naturally rests on the switch 14 in the middle of the groove with a vertical depth of 2mm; the friction coefficient of the rubber sleeve 13 during inflation is >0.8 (refer to GB / T5330), so it can still be held stably even if the palm is sweaty; the trigger pressure of the switch 14 is 1.5N, and the pressing stroke is 0.8mm, realizing micro-force control of the fingertips.

[0043] The working process of this utility model is as follows:

[0044] The user first inserts the connector 41 on the top of the battery block 4 vertically into the connector slot of the base 3, and then tightens the fixing buckles 42 on both sides with screws to complete the power supply connection. Then, the user rotates and fixes the connecting post 21 at the tail end of the gun head 2, aligning the screw-on protrusion 211 with the screw-on slot 121 of the air inlet 12, and inserts the connector 221 at the front end of the air inlet 22 into the air bag interface. After holding the handle of the gun body 1 and pressing the switch, the lithium battery drives the motor to draw in air from the air inlet 11. The airflow is rectified and accelerated by the guide plate 122 in the air inlet 12, and injected into the air bag at high speed through the gas channel of the gun head 2. When the battery needs to be replaced, the user removes the screws, pulls out the battery block 4, presses the buckle of the detachable plate 43 to replace the lithium battery, and reassembles it. The time taken is ≤3 minutes. When switching the air interface type, the user rotates the gun head 2 in the opposite direction to replace the compatible air inlet 22. The entire process can be operated with one hand and the weight of the whole machine is ≤500g.
