Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of inflator pump, specifically to a battery built -in inflator pump. BACKGROUND

[0002] Inflator pump is also called air compressor, air pump and inflator, which is a kind of equipment that fills air into various inflatable objects. Some small inflator pumps are permanently fixed with the inflatable object and the inflating pipe of the pump body in order to pursue compact structure, without designing a detachable interface, so when the inflator pump is damaged or needs to be replaced, it cannot be disassembled and replaced, which limits the connection flexibility of the inflator pump and the inflatable object. SUMMARY

[0003] Therefore, the utility model provides a battery built -in inflator pump, which aims to solve the problem that the inflator pump and the inflatable object cannot be disassembled in the prior art.

[0004] To achieve the above purpose, the utility model realizes the following technical scheme: a battery built -in inflator pump, comprising:

[0005] A shell is provided with an inflator pump, the upper end of the inflator pump is provided with an air outlet, the lower end is provided with an air inlet, and the lower end of the shell is provided with a through slot on one side;

[0006] An operating plate is arranged in the through slot, an electric circuit board is arranged between the operating plate and the inflator pump, and the switch contact on the electric circuit board is arranged opposite to the button on the operating plate;

[0007] A battery is arranged below the inflator pump in the shell, the battery is electrically connected with the electric circuit board, and the electric circuit board is electrically connected with the inflator pump;

[0008] A connecting pipe is arranged on the inflator pump, the lower end of the connecting pipe is communicated with the air outlet, and the upper end of the connecting pipe penetrates through the shell and is communicated with the air inlet of the inflatable object through a quick release assembly.

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

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

[0011] A clamping sleeve is connected with the lower surface of the installation plate on the upper end;

[0012] A clamping assembly is arranged between the lower end of the clamping sleeve and the air inlet, and is used 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.

[0016] A further improvement of this invention is that the battery is provided with a charging port.

[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 a battery-embedded 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 provides the power source for the whole system by being electrically connected with the circuit board 14, and 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 when the button 131 is pressed 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 to transmit the high-pressure air 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 requirement.

[0032] Specifically, the battery 15 has the advantages of improved safety, compact overall structure, enhanced dustproof and waterproof performance and the like in the shell 10.

[0033] As an embodiment, the utility model discloses a battery built-in inflator Figure 3 to the attached Figure 5It can be seen that the quick release assembly 20 comprises 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 a clamping sleeve 22 is connected with the lower surface of the mounting plate 21; a 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 comprises 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 at the front of a first end of the annular convex plate 31, a stop block 311 is fixedly arranged at a 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.

[0034] 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. The connecting pipe 16 is continuously rotated, 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, the protrusion 321 drives the entire annular convex plate 31 to produce a certain degree of displacement downward under the pressing action of the clamping blocks 161. As the connecting pipe 16 is continuously rotated, 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 161 are limited at both ends.

[0035] 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 the protrusion 321 drives the entire annular convex plate 31 to produce a certain degree of displacement downward under the pressing action of the clamping blocks 161. As the connecting pipe 16 is continuously rotated, 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 air 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.

[0038] 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.

[0039] As an embodiment, the shell 10 is provided with a through slot 12, and the connecting pipe 16 is arranged in the through slot 12. Figure 1 It can be known that the protective plate 19 is arranged between the inner wall of the through slot 12 and the operation plate 13, the inner wall of the protective plate 19 is threadedly connected with the outer wall of the operation 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.

[0040] The protective plate 19 can prevent external objects from accidentally hitting or scratching the operation plate 13 and the circuit board 14 behind the operation plate 13, avoid damage to the buttons 131 on the operation plate 13, the connector 151 or the electronic elements on the circuit board 14 due to external force, and thus ensure the normal operation of the inflation pump 11 and the stability of the circuit function.
