Description

Technical Field

[0001] This application relates to the field of balloon technology, and more particularly to a dual-mode balloon inflation nozzle and a dual-mode balloon. Background Technology

[0002] The dual-mode balloon is a new type of weather balloon. Its main structure consists of a nested inner and outer balloon. The balloon's outer skin is typically made of natural rubber with various additives, and it is filled with hydrogen or helium, which is less dense than air, to achieve buoyancy and lift. During use, the buoyancy generated by the inflated outer balloon provides the system's lift, carrying the detection instruments to a preset detection altitude. After the outer balloon bursts, the buoyancy generated by the inflated inner balloon balances the system's weight, allowing it to continue carrying the detection instruments for drifting and horizontal exploration. Compared to traditional weather balloons that only have an ascent phase, the dual-mode balloon can achieve a three-stage exploration process—ascent, horizontal drift, and descent—with a single deployment, significantly improving detection efficiency.

[0003] In recent years, with the continuous development and utilization of near-space resources, dual-mode balloons have great development potential in various fields such as upper-air meteorological detection, regional disaster prevention, environmental monitoring, and regional communication due to their low price and portability. They can realize greater application value by utilizing latex balloons.

[0004] The working principle of the dual-mode balloon is that the outer sphere provides buoyancy power, carrying the system to the target altitude. After the outer sphere bursts, the buoyancy generated by the buoyant gas filling the inner sphere balances the system's weight, and the system enters a horizontal drift state. To achieve this process, precise control of the balloon's inflation volume is required during ground deployment. However, the current inflation method is manual, inflating the inner and outer spheres sequentially. Controlling the inflation volume relies on pre-judgment and post-measurement verification, requiring multiple repetitions. This is cumbersome, inefficient, and increases the risk of balloon skin damage. Furthermore, since both the inner and outer spheres are filled with low-density gas, inflating one sphere before inflating the other presents challenges. Utility Model Content

Detailed Implementation

[0048] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0049] It should be noted that, unless otherwise defined, the technical or scientific terms used in one or more embodiments of this specification should have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains.

[0050] To facilitate understanding of the dual-mode balloon inflator provided in this application embodiment, its application scenario is first explained. The dual-mode balloon inflator provided in this application embodiment is used in dual-mode balloons for inflating them. Currently, dual-mode balloons can only inflate either the inner or outer balloon at a time, generally requiring repeated operations to accurately control the inflation volume, resulting in low inflation efficiency. Furthermore, repeated operations increase the risk of damage to the balloon skin. Additionally, the low density of the inflated gas causes some inconvenience during inflation. Therefore, this application embodiment provides a dual-mode balloon inflator to improve the inflation effect of dual-mode balloons. A detailed description follows with reference to the accompanying drawings and embodiments.

[0051] refer to Figure 1 As shown, Figure 1 This diagram illustrates an application scenario of the dual-mode balloon inflator provided in this embodiment. It also shows the state of the dual-mode balloon inflator when assembled onto a dual-mode balloon. The dual-mode balloon inflator is mounted on the handle of the dual-mode balloon. The dual-mode balloon includes a nested inner sphere 500 and an outer sphere 400, with the inner sphere 500 nested inside the outer sphere 400. During inflation, both the inner sphere 500 and the outer sphere 400 need to be inflated separately. When the dual-mode balloon is in use, the outer sphere 400 is used for the balloon's ascent; when the balloon reaches a set height, the outer sphere 400 is controlled to burst. The inner sphere 500 is used for the balloon's levitation after reaching the set height, allowing it to float within that range.

[0052] When inflating the inner sphere 500 and the outer sphere 400, inflation can be performed through the dual-mode balloon inflator provided in this embodiment. Combined with... Figure 1 As can be seen, the main structure of the dual-mode balloon inflator disclosed in this application includes a valve assembly 300, a support base 100, and a noise muffler 200. The support base 100 serves as a support structure to support the valve assembly 300 and the noise muffler 200, and when connected to the inner ball 500 and the outer ball 400, it is also fixedly connected to both balls (inner ball 500 and outer ball 400) via the support base 100. The valve assembly 300 is used to inflate the inner ball 500 and the outer ball 400, and includes an inner ball 500 inflation valve and an outer ball 400 inflation valve. The inner ball 500 inflation valve is used to inflate the inner ball 500, while the outer ball 400 inflation valve is used to inflate the outer ball 400. The noise muffler 200 is fitted onto the outside of the support base 100 and is used to reduce the noise generated by the high-speed airflow when inflating the outer ball 400. The structure will be described in detail below with reference to the accompanying drawings.

[0053] Please refer to the above. Figure 2 , Figure 3 and Figure 4 , Figure 2 This paper shows a schematic diagram of the structure of the dual-mode balloon inflation nozzle provided in an embodiment of this application. Figure 3 An exploded view of the dual-mode balloon inflation nozzle provided in an embodiment of this application; Figure 4 A cross-sectional view of the dual-mode balloon inflator provided in this embodiment is shown. The main structure of the dual-mode balloon inflator provided in this embodiment includes a support base 100, a valve assembly 300, and a silencer 200. The valve assembly 300 is disposed within the support base 100, and the silencer 200 is fitted over the support base 100. The inner balloon inflation valve 310 and the outer balloon inflation valve 320 in the valve assembly 300 are arranged side-by-side, and a channel is provided on the support base 100 to cooperate with the inner balloon inflation valve 310 and the outer balloon inflation valve 320, so that the inflation device can inflate the inner and outer balloons respectively through the inner balloon inflation valve 310 and the outer balloon inflation valve 320.

[0054] The support base 100 provided in this embodiment includes a base 110 and a cover 120. The cover 120 is fastened to the base 110 and fixedly connected to the base 110. When the support base 100 is engaged with the inner and outer balls, the base 110 is used to fix the outer ball, and the cover 120 is used to fix the inner ball. For example, the ball handle base 110 or the cover 120 can be tied with a ball strap, cable tie, or sealing tape to fix the dual-mode balloon inflation nozzle to the inner and outer balls respectively.

[0055] Additionally, the base 110 of the support 100 and the cover 120 form a receiving space 1000 for accommodating the valve assembly 300. When engaged with the valve assembly 300, the inner ball valve 310 and the outer ball valve 320 of the valve assembly 300 are fixed within the receiving space 1000, providing stable support for the inner ball valve 310 and the outer ball valve 320. When the valve assembly 300 is fixed within the receiving space 1000, the cover 120 and the base 110 are aligned along the axial direction of the valve assembly 300.

[0056] The inner ball inflation valve 310 is an open valve at both ends, with one end serving as the air inlet and the other as the air outlet. The outer ball inflation valve 320 is an open valve at one end and closed at the other, with an air outlet slit 321 on one side. The open end of the outer ball valve serves as the air inlet for the outer ball inflation valve 320.

[0057] Please refer to the above. Figure 4 , Figure 5 , Figure 7When the support 100 mates with the valve assembly 300, the base 110 is provided with a first inflation hole 1151 that mates with the opening at one end of the inner ball inflation valve 310, and the cover 120 is provided with an air outlet 1231 that mates with the other end of the inner ball inflation valve 310. When the inner ball inflation valve 310 is fixed within the receiving space 1000, the air inlet of the inner ball inflation valve 310 communicates with the first inflation hole 1151, and the air outlet of the inner ball inflation valve 310 communicates with the air outlet 1231. During inflation, external airflow can enter the inner ball inflation valve 310 through the first inflation hole 1151 and flow through the air outlet 1231 into the inner ball.

[0058] In addition, the base 110 is also provided with a second inflation port 1152 that communicates with one end opening of the outer ball inflation valve 320. The air outlet 321 of the outer ball inflation valve 320 communicates with the receiving space 1000, and there is an inflation channel between the base 110 and the cover 120, which communicates with the receiving space 1000. When the outer ball inflation valve 320 is fixed in the receiving space 1000, the air inlet of the outer ball inflation valve 320 communicates with the second inflation port 1152, and the air outlet 321 communicates with the receiving space 1000, and flows out through the inflation channel. During inflation, the external airflow enters the outer ball inflation valve 320 through the second inflation port 1152, enters the receiving space 1000 through the air outlet 321, and finally flows into the outer ball through the inflation channel.

[0059] It should be understood that when the inner ball inflation valve 310 is set, the internal channel of the inner ball inflation valve 310 is isolated from the receiving space 1000 to ensure that the gas inflated into the inner ball can only enter the outer ball through the inner ball inflation valve 310. That is, when the support base 100 and valve assembly 300 are set, the flow channels for inflating the inner ball (first inflation hole 1151, inner ball inflation valve 310, air outlet 1231) and the flow channels for inflating the outer ball (second inflation hole 1152, outer ball inflation valve 320, receiving space 1000, inflation channel) are isolated from each other to achieve independent inflation of the inner ball and the outer ball.

[0060] When the silencer 200 is installed, it is fixedly connected to the base 110 to support it. Additionally, the silencer 200 covers the cover 120 with a gap between them. When the support 100 is fixedly connected to the inner and outer spheres, the outer sphere is fitted outside the silencer 200, and the inner sphere is fitted inside. The inflation channel is located between the silencer 200 and the connection between the cover 120 and the inner sphere, ensuring that gas can flow through the inflation channel into the outer sphere and that the silencer 200 guides the gas flow, reducing noise generated by high-speed airflow.

[0061] As can be seen from the above description, in the technical solution disclosed in this application, by using a support base 100 in conjunction with an inflation device, and by setting an inner ball inflation gate 310 and an outer ball inflation gate 320 within the support base 100 for separately inflating the inner and outer balls, the inner and outer balls of the dual-mode balloon can be inflated simultaneously or separately, thereby improving inflation efficiency, better controlling the inflation volume, and reducing the risk of balloon skin damage caused by repeated manual inflation operations. The dual-mode balloon inflation nozzle features convenient and efficient assembly and high sealing reliability.

[0062] Continue to refer to Figure 3 , Figure 4 and Figure 7 As shown, when the base 110 and the cover 120 are specifically connected, they are fixedly connected by snap-fit, avoiding air leakage and cross-contamination caused by the lack of sealing in the screw holes when using screw connections. This also greatly simplifies the operation and improves assembly efficiency. When the base 110 and the cover 120 are connected by snap-fit, there are gaps only at the mating end faces and the snap-fit ​​positions. There are no gaps in the part of the cover 120 that inserts into the inner ball, thus preventing communication between the receiving space 1000 and the inner ball and avoiding cross-contamination.

[0063] When inflating the outer ball, the aforementioned inflation channel is the assembly gap between the base 110 and the cover 120. This includes the gap between the mating end faces of the base 110 and the cover 120, and the mating gap generated at the position of the snap fastener 122 when the snap fastener 122 is used for mating.

[0064] Please refer to the above. Figure 5 , Figure 6 and Figure 7 , Figure 5 and Figure 6 The diagram shows the structure of the base 110 at different angles. Figure 7 A schematic diagram of the cover 120 is shown. When the base 110 and the cover 120 are specifically fitted together, a slot 113 is provided on the base 110, and a corresponding buckle 122 is provided on the cover 120. During fitting, the buckle 122 is inserted into the slot 113, thereby achieving a fixed connection between the base 110 and the cover 120. In this structure, the buckle 122 is placed on the cover 120, rather than the slot 113, to avoid creating a groove in the cover 120, thus ensuring the structural strength of the cover 120 and preventing air leakage due to grooving. Alternatively, as an optional solution, a guide groove is also provided on the base 110 to mate with the slot 113. During assembly, the buckle 122 can slide into the slot 113 through the guide groove, facilitating the fitting of the buckle 122 and the slot 113.

[0065] In one optional embodiment, multiple latches 122 are used to ensure the connection strength between the cover 120 and the base 110. For example, four latches 122 are used, evenly distributed on the end face of the cover 120 facing the base 110. This ensures both the connection strength between the base 110 and the cover 120 and the uniformity of force distribution between them.

[0066] Continue to refer to Figure 5 , Figure 6 and Figure 7 When the base 110 and cover 120 are engaged with the valve assembly 300, structures for fixing the valve assembly 300 are provided on the cover 120 and the base 110 to ensure that the valve assembly 300 is fixed by the base 110 and the cover 120 when the valve assembly 300 is placed in the receiving space 1000.

[0067] For example, when fixing the inner ball inflation valve 310, the base 110 is provided with an inner ball inflation valve positioning groove 117, and the cover 120 is provided with an inner ball inflation valve positioning post 123. When the inner ball inflation valve 310 is fixed in the receiving space 1000, one end of the inner ball inflation valve 310 is fixed in the inner ball inflation valve positioning groove 117, and the inner ball inflation valve positioning post 123 is inserted into the inner ball inflation valve 310. That is, during assembly, the air inlet end of the inner ball inflation valve 310 is inserted into the inner ball inflation valve positioning groove 117, and the first inflation hole 1151 communicates with the inner ball inflation valve positioning groove 117, so that the first inflation hole 1151 can communicate with the air inlet end of the inner ball inflation valve 310. In addition, the vent 1231 is located on the inner ball inflation valve positioning post 123. When the inner ball inflation valve positioning post 123 is inserted into the inner ball inflation valve 310, the vent 1231 can communicate with the inner ball inflation valve 310. It should be understood that the vent 1231 is a through hole that penetrates the inner ball inflation valve positioning post 123.

[0068] In an optional embodiment, the inner ball valve positioning post 123 is provided with a sealing ring groove. A sealing ring placed in the groove can be used to seal the gap between the inner wall of the valve and the positioning post, preventing gas from leaking into the receiving space 1000 of the base 110 and causing leakage or cross-contamination. The inner ball valve positioning post 123 is provided with an air outlet 1231, which can be used not only for the vertical movement of the sealing top rod of the inner ball inflation valve 310, but also for the air inlet for gas to enter the cavity of the cover 120 and then into the inner ball.

[0069] When fixing the outer ball inflation valve 320, the base 110 is provided with an outer ball inflation valve positioning groove 116, and the cover 120 is provided with an outer ball inflation valve positioning post 121; wherein, the second inflation hole 1152 communicates with the outer ball inflation valve positioning groove 116, and the outer ball inflation valve positioning post 121 can be a solid structure. When the outer ball inflation valve 320 is fixed in the receiving space 1000, one end of the outer ball inflation valve 320 is fixed in the outer ball inflation valve positioning groove 116, and the outer ball inflation valve positioning post 121 is inserted into the outer ball inflation valve 320. That is, during assembly, the air inlet end of the outer ball inflation valve 320 is inserted into the outer ball inflation valve positioning groove 116, and the second inflation hole 1152 communicates with the outer ball inflation valve positioning groove 116, so that the second inflation hole 1152 can communicate with the air inlet end of the outer ball inflation valve 320. In addition, the outer ball inflation valve positioning post 121 is a solid structure. When the outer ball inflation valve positioning post 121 is inserted into the outer ball inflation valve 320, the other end of the outer ball valve can be sealed to ensure that the gas passing through the outer ball inflation valve 320 will not enter the inner ball through the outer ball inflation valve positioning post 121. Alternatively, the outer ball inflation valve positioning post 121 can be provided with a sealing top rod movable hole 1211 for the outer ball inflation valve 320 that is not connected to the inner ball, and is only used for the sealing top rod to move vertically up and down with the air pressure during inflation.

[0070] It should be understood that when the outer ball inflation valve positioning post 121 is inserted into the outer ball inflation valve 320, the outer ball inflation valve positioning post 121 will not completely block the air outlet gap 321, so as to ensure that the airflow can flow into the accommodating space 1000 through the air outlet gap 321.

[0071] In one alternative embodiment, the vent 321 is located on the side of the outer ball valve 320 near the cover 120, and a limiting piece 1212 is provided on the outer ball valve positioning post 121 that inserts into the vent 321. This limiting piece 1212 protrudes outward from the outer ball valve positioning post 121, such as... Figure 8 As shown, the vent gap 321 is a notch opened at one end of the outer ball inflation valve 320 near the cover 120. During assembly, the limiting piece 1212 can be inserted into the vent gap 321 along with the outer ball inflation valve positioning post 121. In addition, the limiting piece 1212 can ensure that the inner ball inflation valve 310 and the outer ball inflation valve 320 are assembled with the mating positioning post, avoiding the risk of misassembly.

[0072] Continue to refer to Figure 7 When setting the limiting piece 1212, there can be two limiting pieces 1212, and the two limiting pieces 1212 are set symmetrically. While limiting the outer ball inflation valve 320, more importantly, it prevents the valve and the positioning post from being inserted in the wrong position (two positioning posts with different diameters can also be used to achieve this. In this case, two valves with different inner diameters can be matched with them).

[0073] In one alternative design, the outer wall of the cover 120 is provided with sealing grooves and anti-slip ribs for connecting the inner ball handle to the cover 120 and for binding and sealing.

[0074] In one specific implementation scheme, the first inflation port 1151 and the second inflation port 1152 can be two circular air inlets. The inflation tube of the inflation device can be inserted through these two inflation ports (the first inflation port 1151 and the second inflation port 1152), and the inner and outer balls can be inflated separately through the valves (inner ball inflation valve 310 and outer ball inflation valve 320). As an optional solution, the two inflation ports have different diameters, which can prevent incorrect insertion of the inner and outer ball air tubes and thus ensure the accuracy when using the dual-mode balloon inflation nozzle.

[0075] In an alternative embodiment, the outer ball inflation valve positioning groove 116 and the inner ball inflation valve positioning groove 117 may also have different dimensions to avoid misassembly of the inner ball inflation valve 310 and the outer ball inflation valve 320 during assembly, thus playing a role in preventing mistakes.

[0076] Continue to refer to Figure 5 and Figure 6 The base 110 provided in this embodiment is a cylinder with an internal cavity at its upper end, which is connected to the balloon handle for securing and sealing the outer sphere. The lower end of the cylinder is connected to the inflation device for positioning. Structurally, the base 110 can be divided into a body 111 (cylinder) and a protruding structure 115 disposed on the side of the body 111 facing away from the cover 120. The side of the protruding structure 115 facing away from the body 111 is a vertical positioning surface. When the base 110 is engaged with the inflation device, the protruding structure 115 is inserted into the inflation device, and the vertical positioning surface vertically positions the base 110 and the inflation device. Furthermore, the cavity inside the base 110 extends into the protruding structure 115, and the aforementioned inner sphere inflation door positioning groove 117 and outer sphere inflation door positioning groove 116 are both disposed within the protruding structure 115. The first inflation hole 1151 and the second inflation hole 1152 are also disposed on the protruding structure 115 and are located on the vertical positioning surface.

[0077] In addition, the base 110 provided in this embodiment also includes a horizontal positioning plate 114 fixed to one side of the protruding structure 115. This horizontal positioning plate 114 is used for horizontal positioning with the inflation device. As can be seen from the above description, when the base 110 and the inflation device are engaged, the horizontal positioning plate 114 and the vertical positioning surface can achieve the positioning engagement between the base 110 and the inflation device. This ensures that when the two are connected, the inflation device can maintain sealed communication with the first inflation hole 1151 and the second inflation hole 1152, improving the inflation effect.

[0078] In the specific setup, an inflatable hanging ring 1153 is provided on the vertical positioning surface, while a balloon releaser hanging ring 1141 is provided on the horizontal positioning plate 114. The inflatable hanging ring 1153 is used to secure the balloon with a rope during inflation or launch, or to attach a detection instrument after inflation. The balloon releaser hanging ring 1141 is used to attach the balloon releaser when launching the balloon.

[0079] In an optional embodiment, the base 110 provided in this application has a muffler limiting rib 112 on the side of its body 111 near the cover 120, which cooperates with the muffler 200. The muffler limiting rib 112 is used to support and limit the fixed position of the muffler 200. When assembling the muffler 200, the muffler 200 is fitted onto the muffler limiting rib 112 and fixed in place.

[0080] When setting the slot 113, the slot 113 is located at the lower edge of the soundproof cover limiting rib 112 to avoid the slot 113 affecting the structural strength of the soundproof cover limiting rib 112.

[0081] Both the inner ball inflation valve 310 and the outer ball inflation valve 320 provided in this application embodiment include a valve sealing top rod. An annular sealing platform is provided on the inner wall of the valve. A sealing ring groove is provided at the connection between the rod head and the rod body of the valve sealing top rod. A sealing ring is placed in the sealing ring groove. After a spring is inserted into the rod, the rod head passes through the platform hole through the compression spring, and the sealing ring and the sealing platform make tight contact to achieve a seal. The bottom of the rod head is conical, which facilitates the positioning of the top rod and guides the gas flow during inflation through the gap between the platform and the rod head. The above-described inflation valve is a conventional inflation valve structure and will not be described in detail here.

[0082] The aforementioned valves are the main conduits for gas inflation into the balloon. Therefore, Y-shaped sealing rings are installed on the air inlet sides of both the inner balloon inflation valve 310 and the outer balloon inflation valve 320. Specifically, Y-shaped sealing holes are provided on the air inlet sides of both the inner balloon inflation valve 310 and the outer balloon inflation valve 320 to... Figure 8 Taking the outer ball valve 320 as an example, a Y-shaped ring hole 322 is provided on one side of the air inlet of the outer ball valve 320. The Y-shaped ring hole 322 is used to place a Y-shaped sealing ring. The air inlet pipe of the inflation device can enter from the air inlet and be inserted into the Y-shaped ring hole 322. During inflation, it can seal the air inlet pipe to prevent gas from leaking to the outside of the inflation nozzle. A sealing ring groove is provided on the outer wall of the valve Y-shaped ring hole 322. A sealing ring is placed in the groove for sealing between the valve and the valve positioning groove, which can prevent gas in the cavity of the base 110 from leaking to the outside of the inflation nozzle. That is, a first sealing ring that cooperates with the inner ball valve 310 is provided in the positioning groove 117 of the inner ball valve; a second sealing ring that cooperates with the outer ball valve 320 is provided in the positioning groove 116 of the outer ball valve.

[0083] The silencer 200 provided in this embodiment separates the inner and outer ball handles, leaving a gap at the overlap of the inner and outer ball handles to facilitate smooth airflow into the outer ball, preventing whistling and static electricity caused by airflow obstruction due to the tight fit of the inner and outer ball handles. The cover platform of the silencer 200 is fitted with the silencer 200 limiting rib 112 on the base 110, and the cover body of the silencer 200 maintains a certain distance from the outer wall of the cover body 120. The outer ball handle is fitted into the outer wall of the silencer 200 and sealed and fixed at the lower edge of the cover platform by cable ties or sealing tape.

[0084] During assembly, the cover 120 is placed on a horizontal platform with the buckle 122 end facing upwards. The valve sealing rod is then fitted into the sealing ring and spring, the valve into the Y-ring and valve sealing ring, and the positioning pin is fitted into the sealing ring. The sealing rod is then inserted into the valve, and the valve is fitted into the positioning groove of the base 110 and the positioning pin of the cover 120. At this point, the four buckles 122 on the cover 120 are precisely positioned in the four guide slots of the base 110. A uniform force is applied vertically, pushing the buckles 122 into the slots 113, completing the assembly of the inflation nozzle. This assembly method requires no additional tools, offering advantages such as ease of operation, high assembly efficiency, and high component sealing reliability.

[0085] The dual-mode balloon inflator is mainly used for assembling dual-mode weather balloons. A dual-mode weather balloon consists of an inner balloon, an outer balloon, and an inflator. The inner and outer balloons are nested, with the inner balloon inserted inside the outer balloon. The balloon handles are located at the same end, and the inflator overlaps within the two balloon handles. The specific assembly process is as follows:

[0086] Lift the outer balloon vertically upwards with the handle facing up. Insert the inner balloon into the outer balloon through the tail end, then place the balloon horizontally to expel the air. Take the dual-mode weather balloon inflation nozzle and insert the inner balloon handle into the sealing groove of the nozzle cover 120. Secure the handle to the sealing groove with a balloon belt, cable tie, or sealing tape, ensuring there is no air leakage between the handle and the nozzle cover 120. Then, insert the base 110 of the inflation nozzle into the silencer 200. Insert the outer balloon handle base 110 from the outer wall of the silencer 200, extending beyond the cover platform. Secure the handle to the lower edge of the silencer 200 cover platform with a balloon belt, cable tie, or sealing tape, ensuring there is no air leakage between the handle and the inflation nozzle base 110.

[0087] In one alternative design, the valve employs a split structure. During the sealing process, in addition to considering the seal between the valve's internal sealing pushrod and the valve itself, the seal between the valve and the air inlet of the base 110, as well as the seal between the inner ball inflation valve 310 and the valve positioning post of the cover 120, also needs to be considered. The advantages of using a split structure are that each component has a relatively simple structure, is easy to manufacture, has low mold opening difficulty and cost, and requires minimal mold modifications when subsequently optimizing the design of each component.

[0088] Alternatively, the valve and the base 110 can be designed as a single unit, such as... Figure 9a and Figure 9b As shown, the base 110 and the valve assembly are an integral structure. That is, the valve assembly and the base 110 are integrated into one unit. Since the diameter of the Y-shaped sealing ring is larger than the air inlet (to avoid pulling out the Y-shaped ring when the air inlet pipe is in or out), in order to facilitate the insertion of the Y-shaped sealing ring into the valve Y-shaped ring hole and to consider the load-bearing requirements of the hanging ring, the air inlet panel is designed separately. Hollowing out the vertical positioning surface around the hanging ring, after the Y-shaped sealing ring is inserted into the Y-shaped ring hole, a sealing plate 118 of the same size as the hollowed-out part is then covered. The sealing plate 118 is flush with the vertical positioning surface. The sealing plate 118 has a buckle in the center, which can form a buckle fixation with the buckle hole at the corresponding position of the base 110. At the same time, in order to prevent the ends of the air inlet of the sealing plate 118 from warping and deforming, a boss is provided on the side of the sealing plate 118, and a groove is made on the mating surface of the base 110 and the side of the sealing plate 118. The boss of the sealing plate 118 and the groove of the base 110 also form a ring buckle fixation. The advantage of this design is that it reduces the need for sealing between the valve and the air inlet of the base 110.

[0089] Please refer to the above. Figure 10 , Figure 11 and Figure 12 , Figure 10 , Figure 11 and Figure 12 Two other structural variations of the dual-mode balloon inflator nozzle are illustrated. Figure 10 , Figure 11 and Figure 12 Some of the labels in the text can be referenced. Figure 3 The same label in Figure 10 and Figure 11 Two other connection methods between the base 110 of the support and the cover 120 are illustrated. For example... Figure 10 As shown, in Figure 10 In the illustrated design, the base 110 and the cover 120 are partially nested, connected by a threaded connector (bolt or screw) at the nested portion. A through hole 101 (inflation channel) communicating with the receiving cavity can be provided on the nested portion to allow the outer ball inflation valve to inflate the outer ball. It should be understood that the threaded connector is positioned outside the connection between the cover 120 and the inner ball handle to prevent air leakage after the cover 120 is connected to the inner ball handle. Specifically, the cover 120 is nested inside or outside the base 110, with a through hole 201 on the cover 120 and a corresponding threaded hole 102 on the base 110. The threaded connector passes through the through hole / threaded hole 102 and is threadedly connected to the through hole 201, or vice versa.

[0090] like Figure 11As shown, in another possible embodiment, the base 110 and the cover 120 are connected by a threaded sleeve 130. Exemplarily, the end of the base 110 facing the cover 120 has a first thread 103 with a first direction of rotation, and the end of the cover 120 facing the base 110 has a second thread 202 with a second direction of rotation. The assembly also includes a threaded sleeve 130 with oppositely oriented threads at both ends to match the first thread 103 and the second thread 202. During assembly, the threaded sleeve 130 is threadedly connected to both the cover 120 and the base 110. Rotating the threaded sleeve 130 in one direction thread-connects the base 110 and the cover 120, and tightening it secures the base 110 and the cover 120 together. When disassembly is required, it can be unscrewed in the opposite direction. In addition, when using this solution, a through hole 203 is provided on the cover 120 to connect the receiving space between the cover 120 and the base 110 with the external space through the through hole 203 (inflation channel), so that the outer ball inflation valve can inflate the outer ball. It should be understood that the aforementioned threaded sleeve 130 is located on the outside of the connection between the cover 120 and the inner ball handle to ensure that no air leakage occurs after the cover 120 is connected to the inner ball handle.

[0091] like Figure 12 As shown, in another embodiment, a stud 104 is provided on the base 110, and a mounting hole 204 is provided on the cover 120. The stud 104 is locked by a threaded connector passing through the cover 120, thereby fixing the base 110 and the cover 120 together. In this embodiment, a sealing sleeve is provided on the threaded connector to seal the mounting hole 204 in the cover 120 for the threaded connector to pass through. In addition, a through hole 105 (inflation channel) is provided on the side wall of the base 110 so that the outer ball inflation valve can be inflated.

[0092] This application embodiment also provides a dual-mode balloon, which includes an inner sphere, an outer sphere nested outside the inner sphere, and a dual-mode balloon inflation nozzle as described above; wherein,

[0093] The base 110 is fixedly connected to the outer ball, and the outer ball inflation valve 320 is used to supply air to the outer ball;

[0094] The cover 120 is fixedly connected to the inner ball, and the inner ball inflation valve 310 is used to supply air to the inner ball.

[0095] In the above technical solution, by using a support base 100 in conjunction with an inflation device, and by setting an inner ball inflation gate 310 and an outer ball inflation gate 320 in the support base 100 for separately inflating the inner and outer balls, the inner and outer balls of the dual-mode balloon can be inflated simultaneously, thereby improving inflation efficiency, better controlling the inflation volume, and reducing the risk of damage to the balloon skin caused by repeated manual inflation operations.
