[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0032] Referring to Figures 1 - 3 , an embodiment provided by the present utility model: A magnetic adsorption type quick inflation and air suction device includes: a rubber bladder 1, an air outlet component 2 is installed on the top of the rubber bladder 1, and there is an interference fit between the air outlet component 2 and the through-hole structure at the top of the rubber bladder 1, so that the air outlet component 2 is clamped on the top of the rubber bladder 1 to complete the assembly. At the same time, it is also convenient for users to separate the air outlet component 2 from the rubber bladder 1 later to replace the damaged structure on the air outlet component 2. A connector 3 is provided at the top of the air outlet component 2, and a first magnetic ring 4 is fixedly connected to the outer top of the connector 3. By adapting the connector 3 to the interface on the air inflation protection device or the airbag structure of the air inflation massage and physiotherapy appliance, and then attracting through the first magnetic ring 4 and the magnet on the interface, the quick fixed connection between the device and the air inflation protection device or the air inflation massage and physiotherapy appliance is completed;

[0033] Referring to Figure 1 、 Figure 2 And Figure 6, an air intake assembly, which is installed at the bottom of the rubber bladder 1. A second magnetic ring 6 is installed at the bottom end of the air intake assembly. Through the second magnetic ring 6, the air intake assembly can be connected to the interface on the inflatable protective gear or the airbag structure of the inflatable massage and physiotherapy appliance, and the air in the airbag of the inflatable protective gear or the inflatable massage and physiotherapy appliance can be pumped out by means of the air intake assembly. The air intake assembly includes an air intake valve core 5, which is clamped between the outer side of the air intake valve core 5 and the bottom of the rubber bladder 1. A recessed structure is provided in the middle of the outer side of the air intake valve core 5, and this structure is in interference fit with the notch at the bottom of the rubber bladder 1 to realize clamping the air intake valve core 5 at the bottom of the rubber bladder 1, thus conveniently completing the assembly of the device. At the same time, when the structure on the air intake valve core 5 is damaged, the air intake valve core 5 can also be conveniently disassembled from the rubber bladder 1. The top of the inner wall of the air intake valve core 5 is detachably connected with an air intake hole core 10, and a second rubber pad 11 is arranged at the bottom of the air intake hole core 10. Through the cooperation of the air intake hole core 10 and the second rubber pad 11, it can be ensured that the gas from the outside or the gas in the airbag of the inflatable protective gear or the inflatable massage and physiotherapy appliance can only enter the inside of the rubber bladder 1. The inner side of the second magnetic ring 6 is clamped with the outer periphery bottom of the air intake valve core 5. Through the design of the clamping structure, the quick assembly of the second magnetic ring 6 and the air intake valve core 5 can be realized. The outer diameter of the second rubber pad 11 is smaller than the inner diameter of the upper side inside the air intake valve core 5, and the outer diameter of the second rubber pad 11 is larger than the inner diameter of the lower side inside the air intake valve core 5, so that when the second rubber pad 11 is in contact with the air intake hole core 10, the gas can enter through the inlet at the bottom of the air intake valve core 5 and pass through the gap between the second rubber pad 11 and the inner wall of the air intake valve core 5, and finally enter the rubber bladder 1 after entering the inside of the air intake hole core 10.

[0034] Refer to Figures 1 - 5 , an air outlet assembly, which is installed inside the air outlet component 2. Through the air outlet assembly, the air inside the rubber bladder 1 can be discharged into the airbag structure of the inflatable protective gear or the inflatable massage and physiotherapy appliance, and the air inside the inflatable protective gear or the inflatable massage and physiotherapy appliance will not flow back. The air outlet assembly includes an air outlet valve core 7, which is clamped between the outer side of the air outlet valve core 7 and the inside of the air outlet component 2, so that the quick assembly of the air outlet assembly and the air outlet component 2 can be realized. The top of the inner wall of the air outlet valve core 7 is detachably connected with an air outlet hole core 8, and a first rubber pad 9 is arranged at the bottom of the air outlet hole core 8. When the rubber bladder 1 is squeezed, the gas inside it will move upward and push the first rubber pad 9 against the bottom of the air outlet hole core 8. At this time, the gas inside the rubber bladder 1 can pass through the gap between the first rubber pad 9 and the air outlet valve core 7 and enter the airbag structure of the inflatable protective gear or the inflatable massage and physiotherapy appliance through the air outlet hole core 8. The outer diameter of the first rubber pad 9 is smaller than the inner diameter of the upper side inside the air outlet valve core 7, and the outer diameter of the first rubber pad 9 is larger than the inner diameter of the lower side inside the air outlet valve core 7, so that when the gas in the inflatable protective gear or the inflatable massage and physiotherapy appliance flows back, the gas will push the first rubber pad 9 downward, causing the first rubber pad 9 to move downward to close the channel at the bottom of the air outlet valve core 7, avoiding the phenomenon of gas backflow in the airbag structure of the inflatable protective gear or the inflatable massage and physiotherapy appliance.

[0035] Working principle: When in use, align the interface of the inflatable protective device or inflatable massage and physiotherapy device to be inflated with the top of the air outlet component 2, so that the connector 3 at the top of the air outlet component 2 is aligned with the interface on the airbag of the inflatable protective device or inflatable massage and physiotherapy device. At the same time, during the process, the magnetic ring 4 outside the connector 3 will be magnetically attracted to the magnet on the interface of the airbag of the inflatable protective device or inflatable massage and physiotherapy device, and then quickly connect the connector 3 and the interface of the airbag of the inflatable protective device or inflatable massage and physiotherapy device. Subsequently, the user presses the rubber bladder 1 to compress the air inside it. At this time, the air pressure inside the intake valve core 5 is downward, so the rubber pad 11 will slide downward driven by the air pressure and block on the step inside the intake valve core 5. At this time, the rubber pad 11 closes the channel inside the intake valve core 5, so that the gas inside the rubber bladder 1 cannot be discharged through the intake valve core 5. At the same time, the air pressure inside the outlet valve core 7 is upward, so the bottom of the rubber pad 9 will be pushed upward by the air and stick to the bottom of the air outlet core 8. However, the outer diameter of the rubber pad 9 is smaller than the inner diameter of the outlet valve core 7, so the air will pass through the gap between the rubber pad 9 and the outlet valve core 7 and pass through the inside of the air outlet core 8 and enter the airbag of the inflatable protective device or inflatable massage and physiotherapy device through the connector 3, realizing the inflation of the airbag of the inflatable protective device or inflatable massage and physiotherapy device.

[0036] When the rubber bladder 1 is released, at this time, the rubber bladder 1 will reset and expand due to its own elastic force, and a negative pressure will be formed inside the rubber bladder 1. At this time, the pressure direction inside the outlet valve core 7 is downward, and the rubber pad 9 will be driven by the air pressure to fall to the step inside the outlet valve core 7 to close the inside of the outlet valve core 7. At this time, the connector 3 will not generate suction, thus avoiding sucking out the gas filled in the airbag of the inflatable protective device or inflatable massage and physiotherapy device. At the same time, an upward pressure will be generated inside the intake valve core 5, so that the rubber pad 11 will be pushed upward by the air pressure and then contact the bottom of the intake hole core 10. At this time, the channel inside the intake valve core 5 is in an open state, and the outside air will be sucked into the rubber bladder 1 through the intake valve core 5. When it is necessary to empty the gas in the airbag of the inflatable protective device or inflatable massage and physiotherapy device at this time, just magnetically couple the connector at the bottom of the intake valve core 5 with the interface of the airbag of the inflatable protective device or inflatable massage and physiotherapy device, and repeatedly press the rubber bladder 1 to realize the air extraction action and empty the gas in the inflatable protective device or inflatable massage and physiotherapy device.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
