INNOVATION CONTENT

[0003] Therefore, the utility model provides a kind of inflator of battery external, to solve the problem that inflator and the article to be inflated cannot be disassembled in prior art.

[0004] To achieve the above purpose, the utility model is realized by the following technical scheme: a kind of inflator of battery external, comprising:

[0005] Shell, inflator is arranged in it, the upper end of the inflator is provided with air outlet, the lower end is provided with air inlet, the lower end of the shell one side is provided with through slot;

[0006] Operating plate is arranged in the through slot, switch contact on the circuit board between the operating plate and the inflator is oppositely arranged with the button on the operating plate;

[0007] Battery is arranged outside the shell, the battery is electrically connected with the circuit board by the connector on the operating plate, and the circuit board is electrically connected with the inflator;

[0008] Connecting pipe is arranged on the inflator, the lower end of the connecting pipe is communicated with the air outlet, and the upper end of the connecting pipe is communicated with the air inlet of the article to be inflated through quick-release assembly after penetrating the shell.

[0009] The utility model further improves that the quick-release assembly comprises:

[0010] Mounting plate is sleeved on the air inlet and connected with the air inlet;

[0011] Clamping sleeve, the upper end of the clamping sleeve is connected with the lower surface of the mounting plate;

[0012] Clamping assembly is arranged between the lower end of the clamping sleeve and the air inlet, for clamping the clamping block arranged on the outer circumferential surface of the connecting pipe.

[0013] A further improvement of this utility model is that the snap-fit ​​assembly includes an annular convex plate disposed at the lower end of the snap-fit ​​sleeve. The upper surface of the annular convex plate is parallel to the lower surface of the air inlet end above it and forms a snap-fit ​​groove. The snap-fit ​​groove is adapted to the snap-fit ​​block disposed on the outer circumferential surface of the connecting pipe. An inlet channel is disposed in front of the first end of the annular convex plate, and a stop is disposed at the second end of the annular convex plate. A protrusion is disposed at the lower end of the snap-fit ​​groove near the stop.

[0014] A further improvement of this utility model is that a pressure sensor is provided on one side of the connecting pipe inside the housing, and the detection end of the pressure sensor is connected to the connecting pipe.

[0015] A further improvement of this utility model is that a protective plate is provided between the inner wall of the through groove and the operating plate, the inner wall of the protective plate is threadedly connected to the outer wall of the operating plate, and the side of the protective plate near the outside of the housing extends out of the through groove.

[0017] The technological advancements achieved by this utility model due to the adoption of the above technical solution are as follows:

[0018] This invention provides an external battery-operated air pump. When connecting the connecting tube to the air inlet, the locking block of the connecting tube is aligned with the inlet channel on the annular convex plate. Then, the connecting tube is inserted along the inlet channel, and the locking block begins to enter the locking groove. Once the locking block is fully inside the locking groove through the inlet channel, it is restricted within the groove and can only move along the groove's trajectory. Continuing to rotate the connecting tube, the locking block gradually approaches the stop. Until the connecting tube causes the locking block on its outer circumferential surface to press against the protrusion at the lower end of the locking groove, the locking sleeve, made of a resilient material, causes the protrusion to move downwards under the pressure of the locking block. As the connecting tube continues to rotate, the locking block passes the protrusion and contacts the stop, at which point the protrusion springs back to its initial state, restricting both ends of the locking block.

[0019] When it is necessary to disassemble the connecting pipe, rotate the connecting pipe towards the inlet channel. The connecting pipe causes the locking block on its outer circumferential surface to press against the protrusion at the lower end of the locking groove. Under the pressure of the locking block, the protrusion will cause the entire annular convex plate to shift downward to a certain extent. As the connecting pipe continues to rotate, the locking block passes the protrusion, causing the locking block to exit from the locking groove and disengage from the annular convex plate through the inlet channel, thereby achieving rapid separation of the connecting pipe from the air inlet end. Compared with existing technologies, this method can effectively and quickly disassemble the air pump and the item to be inflated. Attached Figure Description

[0031] The battery 15 is arranged outside the shell 10 and is electrically connected with the circuit board 14 through the connector 151 on the operation plate 13. The connection provides a power source for the whole system, the circuit board 14 is also electrically connected with the inflator 11, so that the electric energy provided by the battery 15 can be transmitted to the inflator 11 to provide power for the operation of the inflator 11. When the button 131 is pressed, the circuit is conducted, and the inflator 11 starts to work; the circuit is disconnected again, and the inflator 11 stops working, so as to control the start and stop of the inflation process. When the inflator 11 inflates, the high-pressure air discharged from the inflator 11 enters the connecting pipe 16 through the air outlet 111, the upper end of the connecting pipe 16 penetrates through the shell 10, the high-pressure air is transmitted to the air inlet end 17 of the article to be inflated, the high-pressure air enters the article to be inflated from the air inlet end 17, and the quick release assembly 20 makes the connection between the connecting pipe 16 and the article to be inflated convenient and fast, and the connecting pipe 16 can be quickly connected or disassembled according to the needs.

[0032] Specifically, the battery 15 arranged outside the shell 10 has the advantages of convenient replacement and maintenance, heat dissipation and design flexibility.

[0033] Specifically, the battery 15 is connected with the connector 151 through a power line.

[0034] As an embodiment, the utility model discloses a battery external inflator Figure 3 to the attached Figure 5It can be seen that the quick release assembly 20 includes a mounting plate 21, which is sleeved on the air inlet end 17 and connected with the air inlet end 17; the upper end of the clamping sleeve 22 is connected with the lower surface of the mounting plate 21; the clamping assembly 30 is arranged between the lower end of the clamping sleeve 22 and the air inlet end 17, and is used for clamping the clamping blocks 161 arranged on the outer circumferential surface of the connecting pipe 16. The clamping assembly 30 includes an annular convex plate 31, which is fixedly arranged at the lower end of the clamping sleeve 22, the upper surface of the annular convex plate 31 is parallel to the lower surface of the air inlet end 17 above the annular convex plate 31, and a clamping groove 32 is formed on the upper surface of the annular convex plate 31, the clamping groove 32 is matched with the clamping blocks 161 fixedly arranged on the outer circumferential surface of the connecting pipe 16, a block passage 33 is arranged in front of the first end of the annular convex plate 31, a stop block 311 is fixedly arranged at the second end of the annular convex plate 31, and a protrusion 321 is fixedly arranged at the lower end of the clamping groove 32 near the stop block 311.

[0035] When the connecting pipe 16 is connected with the air inlet end 17, the clamping blocks 161 of the connecting pipe 16 are aligned with the block passage 33 on the annular convex plate 31. Then, the connecting pipe 16 is inserted in the direction of the block passage 33, and the clamping blocks 161 begin to enter the clamping groove 32. When the clamping blocks 161 completely enter the clamping groove 32 through the block passage 33, the clamping blocks 161 are limited in the clamping groove 32 and can only move along the track of the clamping groove 32. Continue to rotate the connecting pipe 16, and the clamping blocks 161 gradually approach the stop block 311. Until the connecting pipe 16 drives the clamping blocks 161 on the outer circumferential surface to press the protrusion 321 at the lower end of the clamping groove 32, due to the fact that the clamping sleeve 22 is made of a material with toughness, under the pressing action of the clamping blocks 161, the protrusion 321 drives the entire annular convex plate 31 to produce a certain degree of downward displacement. With the continuous rotation of the connecting pipe 16, the clamping blocks 161 pass the position of the protrusion 321 and contact the stop block 311, and the protrusion 321 rebounds to the initial state, so that the clamping blocks are limited at both ends.

[0036] When the connecting pipe 16 needs to be disassembled, the connecting pipe 16 is rotated in the direction of the block passage 33, the connecting pipe 16 drives the clamping blocks 161 on the outer circumferential surface to press the protrusion 321 at the lower end of the clamping groove 32, and under the pressing action of the clamping blocks 161, the protrusion 321 drives the entire annular convex plate 31 to produce a certain degree of downward displacement. With the continuous rotation of the connecting pipe 16, the clamping blocks 161 pass the position of the protrusion 321, so that the clamping blocks 161 are withdrawn from the clamping groove 32 and separated from the annular convex plate 31 through the block passage 33, thereby realizing the quick separation of the connecting pipe 16 and the air inlet end 17. The inflatable pump 11 and the article to be inflated can be effectively and quickly disassembled.

The pressure sensor is electrically connected with the circuit board 14.

[0039] The pressure sensor can obtain the pressure data of the gas in the connecting pipe 16 in real time, and the change of the pressure during the inflation process can be clearly understood. When the pressure in the connecting pipe 16 exceeds the set safety threshold, the pressure sensor can timely detect and transmit the signal to the circuit board 14. The circuit board 14 can automatically stop the work of the inflation pump 11 according to the signal, so as to avoid damage to the inflation pump 11 itself, the connecting pipe 16 and the article to be inflated due to the excessively high pressure.

[0040] As an embodiment, the shell 10 is provided with a through slot 12 on one side, and the through slot 12 is provided with an operating plate 13. Figure 1 As can be seen, the protective plate 19 is provided between the inner wall of the through slot 12 and the operating plate 13, the inner wall of the protective plate 19 is threadedly connected with the outer wall of the operating plate 13, and the side of the protective plate 19 close to the outside of the shell 10 extends out of the through slot 12.

[0041] The protective plate 19 can prevent external objects from accidentally hitting or scratching the operating plate 13 and the circuit board 14 behind it, so as to avoid damage to the buttons 131 on the operating plate 13, the connectors 151 or the electronic elements on the circuit board 14 due to external force, thereby ensuring the normal operation of the inflation pump 11 and the stability of the circuit function.

[0042] As an embodiment, the shell 10 is provided with a through slot 12 on one side, and the through slot 12 is provided with an operating plate 13. Figure 1 As can be seen, the battery 15 is provided with a charging port 152. Specifically, the charging port 152 is a USB interface.
