Description

Technical Field

[0001] The present application relates to the field of balloon technology, and in particular to a dual-mode balloon inflation nozzle and a dual-mode balloon. Background Art

[0002] The dual-mode balloon is a new type of sounding balloon. Its main structure is composed of a double-layer balloon, an inner sphere and an outer sphere. Dual-mode balloons generally use natural rubber as the main material and add various additives to make the balloon skin. It is filled with hydrogen or helium with a density less than that of air to gain buoyancy and rise into the air. When in use, the buoyancy generated by the inflation of the outer sphere provides the system with buoyancy power and carries the detection instrument to the preset detection height. After the outer sphere explodes, the buoyancy generated by the inflation of the inner sphere is in balance with the system's own weight, and the detection instrument continues to be carried for floating and level drift detection. Compared with traditional conventional sounding balloons that only have an ascending stage for detection, dual-mode balloons can achieve three-stage detection of "ascending-level drifting-descending" through a single release, greatly improving the 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 aspects such as high-altitude meteorological detection, regional disaster prevention, environmental monitoring, and regional communications due to their low prices and portability. Latex balloons can be used to achieve greater application value.

[0004] The working principle of the dual-mode balloon is to provide the outer ball with buoyancy power, carry the system to the target height, and then the outer ball explodes. At this time, the buoyancy generated by the buoyancy gas filled in the inner ball reaches a buoyancy balance with the system's own weight, and the system enters a flat floating state. To achieve this process, the inflation volume of the balloon needs to be accurately controlled when it is released from the ground. However, the current inflation method is manual inflation, which inflates the inner ball and the outer ball in turn. The inflation volume is controlled by manual pre-judgment and post-measurement review, which requires repeated operations. The operation is cumbersome and the inflation efficiency is low. Repeated operations increase the risk of damage to the balloon skin. At the same time, since both the inner and outer balls are filled with low-density gas, it will cause certain difficulties to inflate another ball after inflating one ball. Summary of the invention

[0022] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in one or more embodiments of this specification should be understood by people with ordinary skills in the field to which this disclosure belongs.

[0023] To facilitate understanding of the dual-mode balloon inflation nozzle provided in the embodiment of the present application, its application scenario is first explained. The dual-mode balloon inflation nozzle provided in the embodiment of the present application is applied to dual-mode balloons to inflate the dual-mode balloons. When inflating, the current dual-mode balloons can only inflate the inner ball or the outer ball individually, and generally require repeated operations to accurately control the inflation volume, resulting in relatively low inflation efficiency, and repeated operations increase the risk of damage to the balloon skin. At the same time, during inflation, due to the relatively low density of the inflated gas, there will be some inconveniences during inflation. To this end, the embodiment of the present application provides a dual-mode balloon inflation nozzle to improve the inflation effect of the dual-mode balloon, which is described in detail below in conjunction with specific drawings and embodiments.

[0024] refer to Figure 1 As shown, Figure 1 A schematic diagram of an application scenario of a dual-mode balloon inflation nozzle provided in an embodiment of the present application is shown. A schematic diagram of the state of the dual-mode balloon inflation nozzle provided in an embodiment of the present application when assembled to a dual-mode balloon. The dual-mode balloon inflation nozzle provided in an embodiment of the present application is assembled at the handle position of the dual-mode balloon. Among them, the dual-mode balloon includes a nested inner ball 500 and an outer ball 400, wherein the inner ball 500 is nested inside the outer ball 400. When inflating, the inner ball 500 and the outer ball 400 need to be inflated separately. When the dual-mode balloon is in use, the outer ball 400 is used to lift the dual-mode balloon, and when the dual-mode balloon rises to a set height range, the outer ball 400 is controlled to explode. The inner ball 500 is used for the suspension of the dual-mode balloon after reaching a set height range, so that the inner ball 500 can float within the set height range.

[0025] When inflating the inner ball 500 and the outer ball 400, the double-mode balloon inflation nozzle provided in the embodiment of the present application can be used for inflation. Figure 1 It can be seen that the main structure of the dual-mode balloon inflation nozzle disclosed in the present application includes a valve assembly 300, a support seat 100 and a silencer cover 200. Among them, the support seat 100 is used as a support structure to support the valve assembly 300 and the silencer cover 200, and when connected to the inner ball 500 and the outer ball 400, it is also fixedly connected to the two spheres (the inner ball 500 and the outer ball 400) through the support seat 100. The valve assembly 300 is used to inflate the inner ball 500 and the outer ball 400, and it includes an inner ball 500 inflation door and an outer ball 400 inflation door, wherein the inner ball 500 inflation door is used to inflate the inner ball 500, and the outer ball 400 inflation door is used to inflate the outer ball 400. The silencer cover 200 is sleeved on the outer side of the support seat 100, and is used to reduce the noise generated by the high-speed airflow when the outer ball 400 is inflated. The structure is described in detail below in conjunction with specific drawings.

[0026] For reference Figure 2 , Figure 3 and Figure 4 , Figure 2 The structure diagram of the dual-mode balloon inflation nozzle provided in the embodiment of the present application is shown. Figure 3 An exploded schematic diagram of a dual-mode balloon inflation nozzle provided in an embodiment of the present application; Figure 4A cross-sectional view of a dual-mode balloon inflation nozzle provided in an embodiment of the present application is shown. The dual-mode balloon inflation nozzle provided in an embodiment of the present application mainly comprises a support seat 100, a valve assembly 300 and a silencer cover 200. The valve assembly 300 is arranged inside the support seat 100, and the silencer cover 200 is sleeved outside the support seat 100. The inner ball inflation valve 310 and the outer ball inflation valve 320 in the valve assembly 300 are arranged side by side, and a channel cooperating with the inner ball inflation valve 310 and the outer ball inflation valve 320 is provided on the support seat 100, so that the inflation device can inflate the inner ball and the outer ball respectively through the inner ball inflation valve 310 and the outer ball inflation valve 320.

[0027] The support base 100 provided in the embodiment of the present application includes a base 110 and a cover 120, and the cover 120 is buckled on the base 110 and fixedly connected to the base 110. When the support base 100 cooperates with the inner ball and the outer ball, the base 110 is used to be fixedly connected to the outer ball, and the cover 120 is used to be fixedly connected to the inner ball. Exemplarily, the ball handle base 110 or the cover 120 can be tied with a ball belt, a cable tie or a sealing tape, so that the dual-mode balloon inflation nozzle is fixed to the inner ball and the outer ball respectively.

[0028] In addition, the base 110 and the cover 120 of the support seat 100 enclose a receiving space 1000, and the receiving space 1000 is used to receive the valve assembly 300. When the valve assembly 300 is matched, the inner ball inflation valve 310 and the outer ball inflation valve 320 of the valve assembly 300 are fixed in the receiving space 1000, so that the inner ball inflation valve 310 and the outer ball inflation valve 320 can obtain stable support. When the valve assembly 300 is fixed in the receiving space 1000, the cover 120 and the base 110 are arranged along the axial direction of the valve assembly 300.

[0029] The inner ball inflation valve 310 is a valve with two openings, one end of which is an air inlet and the other end of which is an air outlet. The outer ball inflation valve 320 is a valve with one end open and the other end closed, and an air outlet gap 321 is provided on one side of the outer ball inflation valve 320. The open end of the outer ball inflation valve is the air inlet of the outer ball inflation valve 320.

[0030] For reference Figure 4 , Figure 5 , Figure 7When the support seat 100 is matched with the valve assembly 300, the base 110 is provided with a first inflation hole 1151 that matches with the opening of one end of the inner ball inflation door 310, and the cover body 120 is provided with an outlet hole 1231 that matches with the other end of the inner ball inflation door 310. When the inner ball inflation door 310 is fixed in the accommodation space 1000, the air inlet of the inner ball inflation door 310 is communicated with the first inflation hole 1151, and the air outlet of the inner ball inflation door 310 is communicated with the outlet hole 1231. When inflating, the external airflow can enter the inner ball inflation door 310 through the first inflation hole 1151, and flow through the outlet hole 1231 into the inner ball.

[0031] In addition, the base 110 is also provided with a second inflation hole 1152 connected to an opening at one end of the outer ball inflation door 320, and the air outlet gap 321 of the outer ball inflation door 320 is connected to the accommodating space 1000, and an inflation channel is provided between the base 110 and the cover body 120, and the inflation channel is connected to the accommodating space 1000. When the outer ball inflation door 320 is fixed in the accommodating space 1000, the air inlet of the outer ball inflation door 320 is connected to the second inflation hole 1152, and the air outlet gap 321 is connected to the accommodating space 1000, and flows out through the inflation channel. When inflating, the external airflow enters the outer ball inflation door 320 through the second inflation hole 1152, enters the accommodating space 1000 through the air outlet gap 321, and finally flows into the outer ball through the inflation channel.

[0032] It should be understood that when the inner ball inflation door 310 is provided, the internal passage of the inner ball inflation door 310 is isolated from the accommodation space 1000 to ensure that the gas filled into the inner ball can only enter the outer ball through the inner ball inflation door 310. That is, when the support seat 100 and the valve assembly 300 are provided, the flow passage for inflating the inner ball (the first inflation hole 1151, the inner ball inflation door 310, the gas outlet 1231) and the flow passage for inflating the outer ball (the second inflation hole 1152, the outer ball inflation door 320, the accommodation space 1000, the inflation passage) are isolated from each other to achieve independent inflation of the inner ball and the outer ball.

[0033] When the silencer 200 is set, the silencer 200 is fixedly connected to the base 110 to support the silencer 200. In addition, the silencer 200 wraps the cover 120 and is separated from the cover 120 by a gap. When the support seat 100 is fixedly connected to the inner ball and the outer ball, the outer ball is sleeved outside the silencer 200, and the inner ball is sleeved inside the silencer 200. The inflation channel is located between the silencer 200 and the position where the cover 120 and the inner ball are connected to ensure that the gas can flow into the outer ball through the inflation channel, and guide the flow direction of the gas through the silencer 200 to reduce the noise generated by the high-speed airflow.

[0034] It can be seen from the above description that in the technical solution disclosed in the present application, by using the support base 100 to cooperate with the inflation device, and providing the inner ball inflation door 310 and the outer ball inflation door 320 in the support base 100 for respectively inflating the inner ball and the outer ball, the inner ball and the outer ball of the dual-mode balloon can be inflated separately or simultaneously, thereby improving the inflation efficiency, better controlling the inflation amount, and reducing the risk of damage to the balloon skin caused by repeated manual inflation operations. The dual-mode balloon inflation nozzle has the characteristics of convenient and efficient assembly and high sealing reliability.

[0035] Continue to refer Figure 3 , Figure 4 and Figure 7 As shown, when the base 110 and the cover 120 are specifically connected, the base 110 and the cover 120 are fixedly connected by snap-fitting, which avoids air leakage and cross-flow caused by the unsealed screw holes when using screws to connect. At the same time, it greatly simplifies the operation and improves the assembly efficiency. When the base 110 and the cover 120 are connected by snap-fitting, there is a gap between the base 110 and the cover 120 only at the matching end faces and the snap-fitting position, and there is no gap on the part of the structure where the cover 120 is inserted into the inner ball, thereby avoiding the communication between the accommodating space 1000 and the inner ball and avoiding the occurrence of cross-flow.

[0036] When the outer ball is inflated, the inflation channel is the assembly gap between the base 110 and the cover 120, such as the gap between the end faces of the base 110 and the cover 120, and the matching gap generated at the position of the buckle 122 when the buckle 122 is used.

[0037] For reference Figure 5 , Figure 6 and Figure 7 , Figure 5 and Figure 6 Schematic diagrams of the structure of the base 110 at different angles are shown. Figure 7 The schematic diagram of the structure of the cover 120 is shown. When the base 110 and the cover 120 are specifically matched, a card slot 113 is provided on the base 110, and a buckle 122 is correspondingly provided on the cover 120. When matched, the buckle 122 is inserted into the card slot 113, so as to achieve a fixed connection between the base 110 and the cover 120. When the above structure is adopted, the buckle 122 is provided on the cover 120 instead of the card slot 113 on the cover 120, the purpose of which is to avoid grooving on the cover 120, thereby ensuring the structural strength of the cover 120 and avoiding air leakage caused by grooving. In addition, as an optional solution, a guide groove that cooperates with the card slot 113 is also provided on the base 110. During assembly, the buckle 122 can slide into the card slot 113 through the guide groove, which facilitates the matching of the buckle 122 and the card slot 113.

[0038] In an optional solution, there are multiple buckles 122 to ensure the connection strength between the cover 120 and the base 110. Exemplarily, there are four buckles 122, and the four buckles 122 are evenly distributed on the end surface of the cover 120 facing the base 110. On the one hand, the connection strength between the base 110 and the cover 120 is ensured, and the uniformity of the force on the cover 120 and the base 110 is also ensured.

[0039] Continue to refer Figure 5 , Figure 6 and Figure 7 When the base 110 and the cover 120 cooperate with the valve assembly 300 , a structure for fixing the valve assembly 300 is 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 accommodation space 1000 .

[0040] Exemplarily, when fixing the inner ball inflation door 310, the base 110 is provided with an inner ball inflation door positioning groove 117, and the cover body 120 is provided with an inner ball inflation door positioning column 123. When the inner ball inflation door 310 is fixed in the accommodation space 1000, one end of the inner ball inflation door 310 is fixed in the inner ball inflation door positioning groove 117, and the inner ball inflation door positioning column 123 is inserted into the inner ball inflation door 310. That is, during assembly, the air inlet end of the inner ball inflation door 310 is inserted into the inner ball inflation door positioning groove 117, and the first inflation hole 1151 is communicated with the inner ball inflation door positioning groove 117, so that the first inflation hole 1151 can be communicated with the air inlet end of the inner ball inflation door 310. In addition, the air outlet 1231 is provided on the inner ball inflation door positioning column 123, and when the inner ball inflation door positioning column 123 is inserted into the inner ball inflation door 310, the air outlet 1231 can communicate with the inner ball inflation door 310. It should be understood that the air outlet 1231 is a through hole that passes through the inner ball inflation door positioning column 123.

[0041] In an optional solution, a sealing ring groove is provided on the inner ball valve positioning column 123, and a sealing ring is placed in the groove to seal the gap between the inner wall of the valve and the positioning column to prevent the inner ball gas from leaking into the accommodating space 1000 of the base 110 and causing leakage and cross-flow. The inner ball valve positioning column 123 is provided with an air outlet 1231, which can not only be used for the vertical movement of the sealing top rod of the inner ball inflation valve 310, but also serves as an air inlet for the gas to enter the cavity of the cover body 120 and then enter the inner ball sphere.

[0042] When fixing the outer ball inflation door 320, the base 110 is provided with an outer ball inflation door positioning groove 116, and the cover body 120 is provided with an outer ball inflation door positioning column 121; wherein, the second inflation hole 1152 is communicated with the outer ball inflation door positioning groove 116, and the outer ball inflation door positioning column 121 can be a solid structure. When the outer ball inflation door 320 is fixed in the accommodation space 1000, one end of the outer ball inflation door 320 is fixed in the outer ball inflation door positioning groove 116, and the outer ball inflation door positioning column 121 is inserted into the outer ball inflation door 320. That is, during assembly, the air inlet end of the outer ball inflation door 320 is inserted into the outer ball inflation door positioning groove 116, and the second inflation hole 1152 is communicated with the outer ball inflation door positioning groove 116, so that the second inflation hole 1152 can be communicated with the air inlet end of the outer ball inflation door 320. In addition, the outer ball inflation door positioning column 121 is a solid structure. When the outer ball inflation door positioning column 121 is inserted into the outer ball inflation door 320, the other end of the outer ball air valve can be blocked to ensure that the gas passing through the outer ball inflation door 320 does not enter the inner ball through the outer ball inflation door positioning column 121. Alternatively, the outer ball inflation door positioning column 121 can be provided with a sealing push rod movable hole 1211 of the outer ball inflation door 320 that is not connected to the inner ball, which is only used for the sealing push rod to move vertically up and down under the action of air pressure during inflation.

[0043] It should be understood that when the outer ball inflation door positioning column 121 is inserted into the outer ball inflation door 320 , the outer ball inflation door positioning column 121 will not completely block the air outlet gap 321 to ensure that the air flow can flow into the accommodating space 1000 through the air outlet gap 321 .

[0044] In an optional solution, the air outlet gap 321 is arranged on the side of the outer ball inflation door 320 close to the cover body 120, and the outer ball inflation door positioning column 121 is provided with a limiting piece 1212 inserted into the air outlet gap 321. The limiting piece 1212 protrudes outward on the outer ball inflation door positioning column 121, such as Figure 8 As shown, the air outlet gap 321 is a notch opened at one end of the outer ball inflation door 320 close to the cover body 120. During assembly, the stopper 1212 can be inserted into the air outlet gap 321 following the outer ball inflation door positioning column 121. In addition, the stopper 1212 can ensure that the inner ball inflation door 310 and the outer ball inflation door 320 are assembled with the matching positioning column to avoid the risk of misassembly.

[0045] Continue to refer Figure 7 When setting the limit plate 1212, the number of the limit plates 1212 can be two, and the two limit plates 1212 are symmetrically arranged, which can limit the outer ball inflation valve 320 and, more importantly, prevent the valve and the positioning column from being inserted into the reverse position (it can also be achieved by using two positioning columns of different diameters. In this case, only two valves with different inner diameters need to be matched with it).

[0046] In an optional solution, the outer wall of the cover body 120 is respectively provided with sealing grooves and anti-slip ribs for connecting the inner ball handle to the cover body 120 and bundling and sealing.

[0047] In a specific implementation, the first inflation hole 1151 and the second inflation hole 1152 can be two circular air inlets, and the inflation tube of the inflation device can be inserted through the two inflation holes (the first inflation hole 1151 and the second inflation hole 1152), and the inner ball and the outer ball can be inflated respectively through the air valve (the inner ball inflation valve 310 squeezes the outer ball inflation valve 320). As an optional solution, the two inflation holes have different diameters, which can prevent the error of the air inlet pipeline caused by the misinsertion of the inner and outer ball air tubes, thereby ensuring the accuracy when using the dual-mode balloon inflation nozzle.

[0048] In an optional solution, the sizes of the outer ball inflation door positioning groove 116 and the inner ball inflation door positioning groove 117 may be different to avoid the inner ball inflation door 310 and the outer ball inflation door 320 from being assembled incorrectly, thereby preventing mistakes.

[0049] Continue to refer Figure 5 and Figure 6 The upper end of the base 110 provided in the embodiment of the present application is a cylinder with a cavity inside, which is connected to the balloon handle and is used to bundle and seal the outer ball. The lower end of the cylinder is connected to the inflation device and realizes positioning and matching. According to the structural division, the base 110 can be divided into a main body 111 (cylinder) and a protruding structure 115 arranged on the side of the main body 111 away from the cover body 120, wherein the side of the protruding structure 115 away from the main body 111 is a vertical positioning surface. When the base 110 cooperates with the inflation device, the protruding structure 115 is inserted into the inflation device, and the base 110 and the inflation device are vertically positioned through the vertical positioning surface. In addition, the cavity in the base 110 extends into the protruding structure 115, and the above-mentioned inner ball inflation door positioning groove 117 and outer ball inflation door positioning groove 116 are both arranged in the protruding structure 115, and the first inflation hole 1151 and the second inflation hole 1152 are also arranged on the protruding structure 115 and opened on the vertical positioning surface.

[0050] In addition, the base 110 provided in the embodiment of the present application also includes a horizontal positioning plate 114 fixed to one side of the raised structure 115, and the horizontal positioning plate 114 is used to position the inflatable device in the horizontal direction. Combined with the above description, it can be seen that when the base 110 cooperates with the inflatable device, the positioning and cooperation of the base 110 and the inflatable device can be achieved through the cooperation of the horizontal positioning plate 114 and the vertical positioning surface. It is ensured that when the two are connected, the inflatable device can be sealed and connected with the first inflatable hole 1151 and the second inflatable hole 1152, thereby improving the inflation effect.

[0051] In the specific configuration, an inflation ring 1153 is provided on the vertical positioning surface, and a ball releaser ring 1141 is provided on the horizontal positioning plate 114. The inflation ring 1153 is used to connect a rope for fixing during inflation or release, or to hang a detection instrument after inflation. The ball releaser ring 1141 is used to hang the ball releaser when the ball releaser is used to release the balloon.

[0052] In an optional solution, a side of the body 111 of the base 110 provided in the embodiment of the present application close to the cover 120 is provided with a silencer cover limiting rib 112 that cooperates with the silencer cover 200, and the silencer cover limiting rib 112 is used to support and limit the fixed position of the silencer cover 200. When assembling the silencer cover 200, the silencer cover 200 is sleeved on the silencer cover limiting rib 112 and the silencer cover 200 is fixed.

[0053] When the slot 113 is provided, the slot 113 is located at the lower edge of the silencer cover limiting rib 112 to prevent the slot 113 from affecting the structural strength of the silencer cover limiting rib 112 . The inner ball inflation valve 310 and the outer ball inflation valve 320 provided in the embodiment of the present application both include a valve sealing push rod, the inner wall of the valve is provided with an annular sealing step, the connection between the rod head and the rod body of the valve sealing push rod is provided with a sealing ring groove, a sealing ring is placed in the sealing ring groove, after the rod is inserted into the spring, the rod head passes through the step hole by compressing the spring, the sealing ring is in close contact with the sealing step to achieve sealing, and the bottom of the rod head is conical, which is convenient for guiding the positioning of the push rod and can guide the gas flow to pass through the gap between the step and the rod head during inflation. The above-mentioned inflation door is a conventional inflation door structure, which will not be described in detail here.

[0054] The above-mentioned valve is the main pipeline for gas to be inflated into the balloon. Therefore, a Y-shaped sealing ring is provided on the air inlet side of the inner ball inflation valve 310 and the outer ball inflation valve 320. Specifically, a Y-shaped ring hole is provided on the air inlet side of the inner ball inflation valve 310 and the outer ball inflation valve 320 to Figure 8 Taking the outer ball inflation valve 320 shown as an example, a Y-shaped ring hole 322 is provided on one side of the air inlet of the outer ball inflation valve 320, and 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, which can seal the air inlet pipe during the inflation process to prevent gas from leaking out of the inflation nozzle. A sealing ring groove is provided on the outer wall of the valve Y-shaped ring hole 322, and a sealing ring is placed in the groove to seal the valve and the valve positioning groove, which can prevent the gas in the cavity of the base 110 from leaking out of the inflation nozzle. That is, a first sealing ring that cooperates with the inner ball inflation valve 310 is provided in the inner ball inflation valve positioning groove 117; and a second sealing ring that cooperates with the outer ball inflation valve 320 is provided in the outer ball inflation valve positioning groove 116.

[0055] The silencer cover 200 provided in the embodiment of the present application is used to separate the inner and outer ball handles, so that a gap is left at the overlap of the inner and outer ball handles to facilitate the smooth entry of gas into the outer ball, thereby avoiding whistling and static electricity caused by friction due to poor airflow caused by the close fit of the inner and outer ball handles. The cover platform of the silencer cover 200 fits with the silencer cover limiting ribs 112 on the base 110, and the cover body of the silencer cover 200 maintains a certain distance from the outer wall of the cover body 120. The outer ball handle is inserted into the outer wall of the silencer cover 200 and is sealed and fixed at the bottom edge of the cover platform by a cable tie or a sealing tape.

[0056] During the specific assembly, the buckle 122 end of the cover 120 is placed upward on a horizontal surface, and the valve sealing push rod is respectively inserted into the sealing ring and spring, the valve is placed into the Y-shaped ring and the valve sealing ring, and the positioning column is inserted into the sealing ring. Then, the sealing push rod is placed in the valve, and the valve is inserted into the positioning groove of the base 110 and the positioning column of the cover 120. At this time, the four buckles 122 on the cover 120 are just located at the four guide notches of the base 110. Push in evenly in the vertical direction, and the buckle 122 enters the slot 113 to complete the assembly of the inflation nozzle. This assembly method does not require the use of additional tools, has the characteristics of convenient operation, high assembly efficiency, and high component sealing reliability.

[0057] The dual-mode balloon inflation nozzle is mainly used for the assembly of dual-mode weather balloons. The dual-mode weather balloon consists of an inner ball, an outer ball, and an inflation nozzle. The inner ball and the outer ball are nested structures. The inner ball is inserted into the outer ball, and the ball handles are at the same end. The inflation nozzles are overlapped and placed in the two layers of ball handles. The specific assembly process is as follows: Lift the handle of the outer ball upward in the vertical direction, insert the inner ball from the tail end of the ball into the outer ball handle, and then place the ball horizontally to remove the air in the ball. Take the dual-mode weather balloon inflation nozzle, insert the handle of the inner ball into the inflation nozzle to the sealing groove of the handle of the cover 120, and use a ball belt, cable tie or sealing belt to tie the handle in the sealing groove. The tie is to ensure that there is no air leakage between the handle and the cover 120 of the inflation nozzle. Then, the base 110 of the inflation nozzle is inserted into the silencer 200, and the base 110 of the outer ball handle is inserted from the outer wall of the silencer 200 and exceeds the cover of the silencer 200. Then, use a ball belt, cable tie or sealing belt to tie the handle to the lower edge of the cover of the silencer 200. The tie is to ensure that there is no air leakage between the handle and the base 110 of the inflation nozzle.

[0058] In an optional solution, the valve adopts a split structure. In the sealing process, in addition to the sealing between the valve internal sealing push rod and the valve, it is also necessary to consider the sealing between the valve and the air inlet of the base 110, and the sealing between the inner ball inflation valve 310 and the valve positioning column of the cover body 120. The advantage of using a split structure is that the structure of each component is relatively simple, easy to process, easy to open the mold, low mold opening cost, and convenient for subsequent optimization design of each component with minimal mold changes.

[0059] In addition, the valve and the base 110 may also be designed to be integrated, such as Figure 9a and Figure 9b As shown, the base 110 and the valve assembly are an integrated structure. That is, the valve assembly and the base 110 are integrated. Since the diameter of the Y-shaped sealing ring is larger than the air inlet (to prevent the Y-shaped ring from being pulled out when the air inlet pipe enters and exits), in order to facilitate the Y-shaped sealing ring to be placed in the Y-shaped ring hole of the valve, and considering the load-bearing requirements of the hanging ring, the air inlet panel is designed to be separated, and the vertical positioning surface is hollowed out around the vertical positioning surface to avoid the hanging ring. After the Y-shaped sealing ring is placed in the Y-shaped ring hole, a sealing plate 118 of the same size as the hollowed part is covered. The sealing plate 118 is flush with the vertical positioning surface, and there is a buckle in the center of the sealing plate 118, which can be buckled and fixed with the buckle hole at the corresponding position of the base 110. At the same time, in order to prevent the two ends of the air inlet hole of the sealing plate 118 from warping and deforming, a boss is set on the side of the sealing plate 118, and a groove is made on the docking surface between 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-shaped buckle fixation. The advantage of this design structure is that the sealing between the valve and the air inlet of the base 110 is reduced.

It should be understood that the setting position of the above-mentioned threaded connector is located on the outside of the connection between the cover body 120 and the inner ball handle to ensure that there will be no air leakage after the cover body 120 is connected to the inner ball handle. In the specific setting, the cover body 120 is nested on the inside or outside of the base 110, and a through hole 201 is opened on the cover body 120, and a corresponding threaded hole 102 is opened on the base 110.

During assembly, the threaded sleeve 130 is threadedly connected to the cover 120 and the base 110 respectively, and the threaded sleeve 130 is rotated in one direction, so that the base 110 and the cover 120 are threadedly connected respectively, and when tightened, the base 110 and the cover 120 are fixedly connected. When it is necessary to disassemble, it can be unscrewed in the opposite direction. In addition, when this solution is adopted, a through hole 203 is opened on the cover body 120, so that the accommodation space between the cover body 120 and the base 110 is connected to the external space through the through hole 203 (inflation channel), so that the outer ball inflation door can inflate the outer ball. It should be understood that the setting position of the above-mentioned threaded sleeve 130 is located outside the connection between the cover body 120 and the inner ball handle to ensure that there will be no air leakage after the cover body 120 is connected to the inner ball handle.

[0062] like Fig.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 penetrating the cover 120, so that the base 110 and the cover 120 are fixedly connected. When this solution is adopted, a sealing sleeve is provided on the threaded connector to seal the mounting hole 204 opened on the cover 120 for penetrating the threaded connector. 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 inflate the outer ball.
