For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0036] In one embodiment of the present invention, referring to Figure 1-Figure 4 , an air pump adapter 10 is provided, which is applied to an air pump 300. The air pump adapter 10 includes a connector body 100 and a sealing sleeve 200.

[0037] Among them, refer to Figure 1 and Figure 2 The connector body 100 has a mounting cavity 110. The connector body 100 has a mounting port 120 and a connection port 130 at opposite ends thereof, and the connection port 130 is used to connect to the inflation port 310 or the exhaust port 320 of the air pump 300.

[0038] Among them, refer to Figure 1 and Figure 2 The sealing sleeve 200 has a sleeve hole 210 that is arranged through the sealing sleeve 200. The sealing sleeve 200 is installed in the installation cavity 110 from the installation opening 120. The first end of the sleeve hole 210 is connected to the connection opening 130. The sealing sleeve 200 forms a sealing ring 220 at the second end of the sleeve hole 210. The sealing ring 220 protrudes out of the installation opening 120.

[0039] Compared with the prior art, the one or more technical solutions in the air pump adapter 10 provided in the embodiment of the utility model have at least one of the following technical effects:

[0040] Reference Figure 2 and Figure 3 When in use, the user inserts the gas nozzle 20 of the product from the ring hole of the sealing ring 220 into the sleeve hole 210 of the sealing sleeve 200, and seals the sealing ring 220 against the surrounding of the gas nozzle 20 to play a sealing role and prevent air leakage during inflation or degassing. For gas nozzles 20 of different sizes, gas nozzles 20 smaller than the sleeve hole 210 can be inserted from the ring hole of the sealing ring 220 into the sleeve hole 210 of the sealing sleeve 200, and then the sealing ring 220 seals against the surrounding of the gas nozzle 20, so that inflation or degassing can be performed, which has high applicability.

[0041] Furthermore, the sealing sleeve 200 can be made of rubber, silicone or latex, so that the sealing sleeve 200 has good elasticity and sealing performance.

[0042] Further, refer to Figure 2 and Figure 3 The sleeve hole 210 is provided with a plurality of hole segments 211 whose diameters decrease successively from one end close to the sealing sleeve 200 to the other end. There is a gap 230 between the sealing sleeve 200 and the joint body 100. Specifically, the plurality of hole segments 211 of different sizes can be respectively matched and connected with the gas nozzles 20 of different sizes. Since the sealing sleeve 200 is elastic, when the gas nozzle 20 is inserted into the sleeve hole 210 of the sealing sleeve 200 from the ring hole of the sealing ring 220, when the diameter of the gas nozzle 20 is slightly larger than the diameter of one of the hole segments 211, the sealing sleeve 200 can be squeezed to deform elastically outward. The above-mentioned gap 230 provides space for the deformation of the sealing sleeve 200, so that the gas nozzle 20 is sealed and plugged into the sleeve hole 210 of the sealing sleeve 200, the sealing performance is good, which is conducive to inflation or exhaust.

[0043] Further, refer to Figure 2 An inclined guide surface 212 is provided between the two relatively hole sections 211 . The inclined guide surface 212 plays a guiding role, which is conducive to the air nozzle 20 being inserted into the sleeve hole 210 of the sealing sleeve 200 from the ring hole of the sealing ring 220 .

[0044] Further, refer to Figure 2 The size of one end of the sealing sleeve 200 is reduced to form a connecting sleeve 240, and a gap 230 is formed between the connecting sleeve 240 and the joint body 100. A plurality of clamping blocks 111 are arranged around the cavity wall of the installation cavity 110 near the connecting port 130, and one end of the connecting sleeve 240 is clamped between the plurality of clamping blocks 111, so that the sealing sleeve 200 can be installed in the installation cavity 110 from the installation port 120, which is convenient for installation.

[0045] Further, refer to Figure 2 An annular stop 112 is provided at one end of the installation cavity 110 close to the connection port 130 , and the end of the connecting sleeve 240 abuts against the annular stop 112 so that the sealing sleeve 200 is positioned and installed in the installation cavity 110 .

[0046] Further, refer to Figure 1 and Figure 2 One end of the joint body 100 is provided with a connecting ring 140, and the ring opening of the connecting ring 140 is the connecting opening 130. The connecting ring 140 is used to be detachably connected with the inflation opening 310 or the exhaust opening 320 of the air pump 300, which is convenient for use.

[0047] In another embodiment of the present invention, referring to Figure 4 The diameter of the sleeve hole 210 decreases from one end close to the sealing sleeve 200 to the other end to form a cone 213, and there is a gap 230 between the sealing sleeve 200 and the joint body 100. Since the sealing sleeve 200 is elastic, when the gas nozzle 20 is inserted into the sleeve hole 210 of the sealing sleeve 200 from the ring hole of the sealing ring 220, the sleeve hole 210 of the cone 213 can make the gas nozzle 20 squeeze the sealing sleeve 200 to elastically deform outward, and the above-mentioned gap 230 provides space for the deformation of the sealing sleeve 200, so that the gas nozzle 20 can be sealed and inserted into the sleeve hole 210 of the sealing sleeve 200, with good sealing performance, which is conducive to inflation or exhaust.

[0048] In another embodiment of the present invention, referring to Figure 5 and Figure 6 The air pump 300 has the above-mentioned air pump adapter 10.

[0049] Further, refer to Figure 6The air pump 300 includes a housing 330, a motor 340 and a fan blade 350.

The motor 340 is fixed in the inner cavity 331 through a bracket, and the center of the fan blade 350 is fixed to the rotating shaft of the motor 340, and the fan blade 350 is driven by the motor 340 to rotate at a high speed. When the product needs to be inflated, the connection port 130 of the air pump adapter 10 is connected to the air filling port 310, and the air nozzle 20 of the product is inserted from the ring hole of the sealing ring 220 into the sleeve hole 210 of the sealing sleeve 200, and the sealing ring 220 is sealed against the surrounding of the air nozzle 20, and then the fan blade 350 is driven by the motor 340 to rotate at a high speed, and the outside air is drawn into the inner cavity 331 from the air extraction port 320, and the product is inflated from the air filling port 310, the air pump adapter 10 and the air nozzle 20. When the product needs to be exhausted, the connection port 130 of the air pump adapter 10 is connected to the exhaust port 320, and the air nozzle 20 of the product is inserted into the sleeve hole 210 of the sealing sleeve 200 through the ring hole of the sealing ring 220, and the sealing ring 220 is sealed against the four sides of the air nozzle 20. Then, the fan blades 350 are driven by the motor 340 to rotate at high speed, and the air in the product is sucked into the inner cavity 331 through the air nozzle 20, the air pump adapter 10 and the exhaust port 320 and discharged to the outside from the inflation port 310.

[0050] Further, refer to Figure 1 and Figure 6 The inner circumferential walls of the inflation port 310 and the exhaust port 320 are uniformly distributed with a plurality of protrusions 311 in an annular manner, and the outer circumferential wall of the connecting ring 140 of the joint body 100 is uniformly distributed with a plurality of L-shaped grooves 141 in an annular manner. The joint body 100 is rotated to make the plurality of protrusions 311 engage with or disengage from the plurality of L-shaped grooves 141. Specifically, during installation, the plurality of protrusions 311 are respectively inserted into the notches of the plurality of L-shaped grooves 141 of the air pump adapter 10, and then the air pump adapter 10 is rotated to make the plurality of protrusions 311 move into the L-shaped grooves 141, so that the plurality of protrusions 311 are respectively engaged with the plurality of L-shaped grooves 141. When disassembling, the air pump adapter 10 is rotated in the opposite direction to move the multiple latching protrusions 311 to the notches of the multiple L-shaped slots 141 respectively, and then the latching protrusions 311 are removed from the notches of the L-shaped slots 141, so that the multiple latching protrusions 311 are disengaged from the multiple L-shaped slots 141 respectively. The structure is simple and the operation is convenient.
