[0029] As Figures 1 to 4 shown, this embodiment provides a direct plug-in inflating device, which includes a housing 10, a control valve 20, a female seat 30, and a male connector 40. The control valve 20 is located inside the housing 10. One side of the female seat 30 is placed inside the housing 10 and is connected to the control valve 20, and the other side is placed outside the housing 10 and is connected to the male connector 40. When in use, after aligning the connection port of the male connector 40 with that of the female seat 30, the male connector 40 is inserted into the female seat 30 to achieve gas export. The direct plug-and-play connection method can improve the assembly efficiency and reduce the situation of incorrect connection of the air pipe and the control valve 20.

[0030] In this embodiment, the female seat 30 includes a seat body 301. A clamping portion 304 is provided on the circumferential side of the seat body 301. The housing 10 is clamped to the clamping portion 304 so that the female seat 30 can be fixed on the housing 10. Preferably, the clamping portion 304 is arranged in a ring-shaped groove shape to make the clamping faster. One side of the seat body 301 is provided with a first connection head 302. The first connection head 302 is located inside the housing 10 and is connected to the control valve 20.

[0031] Furthermore, a valve nozzle 201 is provided on the control valve 20. The valve nozzle 201 is inserted into the first connection head 302. One or more conical bosses 202 are provided at the top of the valve nozzle 201. The bottom surface of the conical boss 202 and the side wall of the valve nozzle 201 form a stepped shape to increase the friction between the valve nozzle 201 and the first connection head 302, so that the connection between the valve nozzle 201 and the first connection head 302 is more stable and prevent air leakage when transporting air flow. Further, the material of the first connection head 302 is rubber or silica gel. When the first connection head 302 is inserted into the valve nozzle 201, the first connection head 302 deforms under force to wrap the valve nozzle 201 to further prevent air leakage during the transmission process.

[0032] A first through hole 303 communicating with the first connection head 302 is provided inside the seat body 301. One end of the first through hole 303 located outside the housing 10 is inserted and matched with the male connector 40, so that the female seat 30 and the male connector 40 are interconnected, allowing gas to be transmitted to external equipment. Further, using the first connection head 302 to connect to the control valve 20 instead of an air pipe, there is no air pipe extending from inside the housing 10 to interfere with the assembly during assembly, making the installation more convenient.

[0033] Specifically, there are multiple ribs 310 inside the seat body 301, and the ribs 310 are located between the first through hole 303 and the seat body 301. Specifically, the multiple ribs 310 are arranged in a staggered manner to make the structure of the first through hole 303 and the seat body 301 more stable and strengthen the supporting force of the seat body 301.

[0034] Further, a second connector 410 is provided on one side of the male connector 40 close to the seat body 301. The second connector 410 is inserted into the first through hole 303. The length of the first connector 302 is approximately equal to the length of the first through hole 303, and the diameter of the first through hole 303 is greater than or equal to the diameter of the internal through hole of the first connector 302, so that gas can be better conducted into the male connector 40 and the gas consumption during transmission can be reduced. A third connector 420 is provided on the side of the male connector 40 away from the second connector 410. The third connector 420 is used to connect with an external air duct or an external device. Specifically, a plurality of conical protrusions are provided at the end of the third connector 420. This setting can make the connection between the male connector 40 and the external device or the air duct more firm.

[0035] Specifically, there are multiple third connectors 420. Anti-fooling marks 440 corresponding to the multiple third connectors 420 one by one are provided on the housing 10 and the male connector 40 to prevent connection errors when connecting with an external device or an external air duct. The anti-fooling marks 440 can be characters, letters, symbols, etc., without specific limitations.

[0036] Further, the male connector 40 is provided with a clamping member 430, and the housing 10 is provided with a clamping groove 110 that cooperates with the clamping member 430. The clamping member 430 is received in the clamping groove 110. The clamping member 430 includes hooks 431 respectively provided on both sides of the male connector 40. The hooks 431 are clamped with the clamping groove 110, and the hooks 431 can be deformed by force and separated from the clamping groove 110. The end of the hook 431 connected to the male connector 40 is U-shaped, so that there is a space for accommodating the deformation of the hook 431 when the hook 431 is stressed. Further, the end of the hook 431 in contact with the housing 10 is stepped, and the stepped surface can abut against the inside of the housing 10 after the hook 431 enters the clamping groove 110 to form a clamping state to prevent the male connector 40 from falling off the female seat 30. Preferably, the clamping member 430 can be made of a plastic material.

[0037] A reinforcing plate 432 is provided on one side of the clamping member 430 close to the male connector 40, and the reinforcing plate 432 is arranged inside the U-shaped groove. When the male connector 40 is pushed towards the female seat 30, the hook 431 will be subjected to an inward pressure; and when the male connector 40 needs to be disassembled from the female seat 30, the user needs to apply an inward pressure to the hook 431 so that the hook 431 can be detached from the inside of the housing 10. At this time, the reinforcing plate 432 can increase the pressure resistance of the hook 431 and prevent the hook 431 from breaking during the assembly and disassembly process.

[0038] The male connector 40 is assembled onto the female base 30 along the first direction. A guiding inclined surface is provided on the contact surface of the hook 431 with the outer shell 10 along the first direction to facilitate the smoother insertion of the male connector 40 into the clamping groove 110. Herein, the first direction is Figure 2 the x-axis direction in

[0039] In another specific embodiment, a protruding portion 50 is provided on one side of the female base 30. At least one first through hole 303 is provided on the protruding portion. Correspondingly, a protruding portion 50 is also provided on one side of the male connector 40, and at least one second connector 410 is provided on the protruding portion 50. The female base 30 and the male connector 40 are arranged in a shape with a protrusion on one side. The protruding side can enable the user to clearly distinguish the installation direction. When the male connector 40 is plugged into the female base 30, the correct direction can be found just by aligning the protruding sides with each other.

[0040] Certainly, once the above description of the representative embodiments is carefully considered, those skilled in the art will readily understand that various modifications, additions, substitutions, deletions, and other changes can be made to these specific embodiments, and these changes are within the scope of the principles of the present utility model. Therefore, the foregoing detailed description should be clearly understood to be given only by way of illustration and example, and the spirit and scope of the present utility model are defined only by the appended claims and their equivalents.
