[0027] To more clearly illustrate the technical solutions of the embodiments of the present invention, the following will briefly introduce the drawings required for the description of the embodiments. Obviously, the following - described drawings are only some examples or embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, the present invention can also be applied to other similar scenarios based on these drawings. Unless obvious from the language context or otherwise stated, the same reference numerals in the figures represent the same structure or operation.

[0028] As shown in this application and the claims, unless the context clearly indicates an exceptional situation, words such as "a", "an", "one", and / or "the" are not specifically singular and may also include the plural. Generally speaking, the terms "comprising" and "including" only indicate the inclusion of the clearly identified steps and elements, and these steps and elements do not constitute an exclusive list. The method or device may also include other steps or elements.

[0029] Refer to Figures 1 to 7 As shown, the inflating device 10 of this embodiment includes an air inlet nozzle 111. The outer ring of the lower part of the air inlet nozzle 111 is sleeved on the upper part of the mounting ring 110. The outer ring of the mounting ring 110 is sleeved with a mounting seat 102, and the outer ring of the mounting seat 102 is sleeved with a pressure ring 101. There is a gap between the mounting seat 102 and the pressure ring 101, and the gap is used to clamp the edge of the air inlet of the airbag 20. The inner ring of the lower part of the mounting ring 110 is sleeved with a one - way air inlet ring 108, and the inner ring of the one - way air inlet ring 108 is sleeved with an inflatable part 104 through a fixed ring 105. The inflating direction of the inflatable part 104 is towards the inner space of the airbag 20.

[0030] The inflating device 10 of this embodiment is generally in the shape of a cylinder and can be installed in the air - filled model by screwing its external thread into the internal thread of the mounting hole of the air - filled model. Based on the above - mentioned structure of the inflating device 10, the components located in the external space of the airbag 20 include the air inlet nozzle 111, and the components located in the internal space of the airbag 20 include the one - way air inlet ring 108 and the inflatable part 104. Refer to Figure 7As shown in the figure, when it is necessary to fill the internal space of the airbag 20 with gas, the inflator 104 located in the internal space of the airbag 20 is activated, and the gas enters from the gas inlet of the air inlet nozzle 111 and enters the internal space of the airbag 20 through the one-way intake ring 108. When the inflator 104 stops working, due to the one-way intake property of the one-way intake ring 108, the gas filled into the internal space of the airbag 20 can be prevented from flowing out to the external space, automatically maintaining airtightness and preventing gas leakage in the air mold. This inflation device 10 can be applied to air molds that are low-altitude dropped and placed on water or the road surface, and has great application value in the field of air mold inflation use.

[0031] In some embodiments, the air inlet nozzle 111 includes a main air inlet at the upper part and a secondary air inlet on the side, and a detachable protective cover 112 is provided at the main air inlet. In this embodiment, the air inlet nozzle 111 can be provided with air inlets at both its top and side, which can increase the gas entry space and is beneficial to improving the air intake effect. When only partial air intake is required, the protective cover 112 can also be used to cover the main air inlet, and at the same time, it can prevent foreign objects from entering the air inlet nozzle 111.

[0032] In some embodiments, a sealing ring 109 is sleeved between the mounting ring 110 and the mounting seat 102. Since the mounting ring 110 and the mounting seat 102 are generally in a rigid connection relationship, by providing the sealing ring 109 between them in this inflation device 10, the overall airtightness of the inflation device 10 can be improved, preventing the gas filled into the internal space of the airbag 20 from flowing out to the external space, automatically maintaining airtightness, and preventing gas leakage in the air mold.

[0033] In some embodiments, an air leakage prevention valve 106 and / or an air leakage prevention one-way film 107 are arranged in the gas outlet direction of the one-way intake ring 108. In this inflation device 10, only the air leakage prevention valve 106 or the air leakage prevention one-way film 107 can be provided, or both the air leakage prevention valve 106 and the air leakage prevention one-way film 107 can be provided at the same time to further improve the airtightness of the entire inflation device 10 and prevent gas leakage in the air mold. In addition, the air leakage prevention one-way film 107 has the characteristic of one-way air flow, so the gas can flow from the external space to the internal space (taking the airbag 20 as the boundary), and the gas flowing from the internal space to the external space is blocked. In an optimized manner, the material of the air leakage prevention one-way film 107 is soft silicone rubber, and the hardness can be about 30 degrees.

[0034] In some embodiments, the inflator 104 can also be sleeved with a fixing ring 105 through the inner ring of the one-way intake ring 108: an inflator sleeve 103 is sleeved outside the inflator 104, and the outer ring of the inflator sleeve 103 is sleeved with the fixing ring 105. This inflation device 10 makes the connection between the inflator 104 and the one-way intake ring 108 more stable through the inflator sleeve 103, and improves the service life of the inflation device 10.

[0035] In some embodiments, the inflatable member 104 includes a trigger switch 113, and the trigger switch 113 is a remote control switch. For example, the remote control switch adopts radio frequency, Wi-Fi or Bluetooth protocol to achieve unobstructed control within a range of 10 to 100 meters, solving the problem of space limitation of traditional wired switches. In the inflating device 10, the operator can remotely start and stop without contacting the device, improving the operation efficiency. In this embodiment, the inflatable member 104 can also be connected with a battery 114, and the battery 114 has a certain endurance. In case of power failure or other emergencies, the inflating device 10 can continue to operate through the battery 114.

[0036] In some embodiments, the motor adopted by the inflatable member 104 is a DC brushless motor. The DC brushless motor has significant advantages in terms of efficiency, service life, control accuracy, etc. Compared with the traditional brushed motor, the efficiency loss is about 15%-20%, and the electric energy conversion efficiency can reach 85%-95%.

[0037] Another embodiment of the present invention provides an inflatable model, which includes the inflating device 10 as described in the foregoing embodiment, and further includes an airbag 20, wherein the edge of the air inlet of the airbag 20 is hermetically installed in the gap between the mounting seat 102 and the pressure ring 101. The same structure of the inflating device 10 in this inflatable model as that in the foregoing embodiment can be referred to the foregoing embodiment and will not be described herein again.

[0038] This inflatable model has a novel inflating device 10. When the inflatable member 104 is powered on and starts to work, a negative pressure is formed in the internal air path of the air leakage prevention components (including the air leakage prevention valve 106, the air leakage prevention one-way film 107, and the one-way air inlet ring 108). When the air pressure in the internal space of the air leakage prevention components is less than the air pressure in the external space, the air path of the air leakage prevention components is conducted, and the gas fills the internal space of the inflatable model through the air path. After the inflation action is completed, since the air pressure in the internal space of the inflatable model is greater than the external space of the inflatable model, the air leakage prevention components automatically close the air path to achieve the purpose of preventing air leakage. It can be seen that the inflatable model in this embodiment can inflate independently without relying on external inflating tools, and the inflatable model can automatically maintain airtightness after inflation to prevent the gas in the inflatable model from leaking.

Although not explicitly stated here, those skilled in the art may make various modifications, improvements and corrections to the present invention. Such modifications, improvements and corrections are proposed in the present invention, so such modifications, improvements and corrections still belong to the spirit and scope of the exemplary embodiments of the present invention.
