Description

Technical Field

[0001] The invention relates to the technical field of inflatable boats, in particular to an airdrop inflatable boat and an intelligent inflation method. Background Art

[0002] An airdrop inflatable boat is a special inflatable boat designed to be delivered by air (such as using an airplane or helicopter) to waters where rapid deployment is required. This type of inflatable boat is usually characterized by rapid inflation, portability, durability and easy operation, so that it can be quickly deployed and used in an emergency.

[0003] In order to facilitate the transportation of inflatable boats, inflatable boats are generally rolled up and stored. When the airdropped inflatable boat lands, ground personnel use equipment to inflate the inflatable boat into shape. Currently, the inflatable boat has only one inflation port for gas to be pumped in. At this time, when inflating the inflatable boat, a lot of physical strength and energy are required, especially when the inflatable boat is large or requires higher air pressure, it will take more time, which not only increases the fatigue of the operator, but also may affect the inflation speed. As a result, in situations where a large number of inflatable boats are required for rapid deployment, the inflation efficiency of such inflatable boats is low, which may delay the execution of rescue or combat missions. Summary of the invention

[0004] The purpose of the present invention is to provide an airdrop inflatable boat and an intelligent inflation method to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions: An airdrop inflatable boat comprises: a hull, an air intake cavity is arranged on the hull, an air intake window is opened on the air intake cavity, and an air pump is connected to the air intake cavity to inflate the hull; A round support assembly is arranged in the air inlet cavity, and the round support assembly includes a driving structure and round support members. The round support members are arranged in at least three groups equidistantly along the circumferential direction of the air inlet cavity. When the air pump pumps air into the air inlet cavity, the driving structure is actuated to drive the round support members to expand outward, thereby expanding the hull near the connection with the air inlet cavity, thereby expanding the air inlet channel of the hull, and in the process of the hull being expanded, air can be sucked into the interior through the air inlet window at the same time, thereby accelerating the inflation speed; A barrier assembly is also provided in the air intake cavity, and the barrier assembly is connected to the round support member via a trigger assembly. When the round support member is actuated, the trigger assembly can drive the barrier assembly to block the air intake window and the driving structure, thereby increasing the flow speed of the gas.

[0006] The air-drop inflatable boat as described above: the driving structure includes an impeller rotatably mounted in the air inlet chamber, a screw is coaxially fixedly arranged on the impeller, and a threaded sleeve is provided on the screw to be threadedly connected thereto.

[0007] The airdrop inflatable boat as described above: the circular support member includes support plates, and the support plates are arranged in at least three groups equidistantly along the circumferential direction of the screw rod, each group of the support plates is connected to the threaded sleeve through a hinged rod, and the support plates are connected to the guide member arranged in the air inlet cavity.

[0008] The airdrop inflatable boat as described above: the guide member includes a fixing frame fixedly arranged in the air inlet cavity, the screw rod passes through the fixing frame, and the fixing frame is fixedly provided with at least three groups of support rods equidistantly along its circumferential direction, the support rods are provided with movable grooves, and the support plates are slidably arranged in the movable grooves.

[0009] The airdrop inflatable boat as described above: the trigger assembly includes an elastic structure and a guide structure, the elastic structure includes a fixed rail arranged in the air inlet cavity, a plug-in cylinder is slidably arranged in the fixed rail, a first spring is slidably arranged in the plug-in cylinder, one end of the first spring abuts against the plug-in cylinder, and the other end abuts against a plug-in rod slidably arranged in the plug-in cylinder, a pulley is installed at the end of the plug-in rod away from the fixed rail, and the plug-in rod is connected to a sealing ring slidably arranged in the air inlet cavity.

[0010] The airdrop inflatable boat as described above: the guide structure includes a slide rail fixedly arranged in the air intake cavity, and the pulley is slidably arranged in the slide rail. During the sliding of the plug-in cylinder relative to the fixed rail, the pulley cooperates with the slide rail to drive the blocking ring to move rapidly along the axial direction of the air intake cavity, thereby blocking the air intake window.

[0011] The airdrop inflatable boat as described above: the baffle assembly includes a baffle rotatably installed in the air inlet cavity, and the baffles are symmetrically arranged in two groups along the length direction of the fixed rail. The sides of each group of baffles are provided with a slide groove, and the slide groove is driven by a trigger member arranged on the sealing ring and can be deflected relative to the air inlet cavity, thereby blocking the impeller.

[0012] The airdrop inflatable boat as described above: the trigger member includes a trigger plate fixedly arranged on the blocking ring, and the trigger plate is symmetrically arranged in two groups along the length direction of the baffle, and each group of the trigger plates is fixedly provided with two groups of protruding columns, and the protruding columns are correspondingly slidably arranged in the sliding groove.

[0013] As described above, the airdrop inflatable boat: a deflation component is also provided in the air inlet cavity, and the deflation component includes an unlocking rod sealingly and slidably arranged in the air inlet cavity, one end of the unlocking rod immersed in the air inlet cavity is fixedly provided with a first trigger rod, and the other end is fixedly provided with a positioning block, and a second spring is also slidably provided on the unlocking rod, one end of the second spring abuts against the first trigger rod, and the other end abuts against the inner wall of the air inlet cavity.

[0014] An airdrop inflatable boat and an intelligent inflation method are also proposed. The airdrop inflatable boat as described above is used, and the method comprises the following steps: Step 1: connecting an air pump to an air inlet cavity, and then starting the air pump. The airflow pumped into the air inlet cavity forces the impeller to rotate. Then, the screw drives the threaded sleeve toward the impeller. At this time, with the cooperation of the guide member, the support plate expands outward, and the wrinkled hull can be stretched open, thereby widening the air inlet channel; Step 2: During the expansion process, the support plate can drive the elastic structure to gradually move away from the axis of the air inlet cavity. When the support plate is expanded to the maximum, the elastic structure automatically moves quickly toward the impeller, thereby driving the blocking ring to block the air inlet window; Step three: When the sealing ring moves toward the impeller, the trigger member arranged on the sealing ring can drive the two sets of baffles to move away from each other, thereby shielding the impeller to reduce the resistance encountered by the gas in the air intake chamber during the pumping process, thereby speeding up the inflation speed. When there is sufficient gas in the hull, remove the air pump.

[0015] Compared with the prior art, the present invention has the following beneficial effects: By setting a rounding component, the driving structure and the guide member cooperate to drive the rounding member to expand outward, thereby rounding the connection section between the hull and the air intake cavity, widening the air intake channel of the rubber part of the hull, so that the gas entering the hull through the air intake port of the air intake cavity can be quickly filled to various areas of the hull, which is convenient for rapid shaping of the hull; At the same time, when the rounding piece is in the rounding operation, the negative pressure state generated by the rubber part of the hull can inhale the external gas through the air inlet window, and then can further accelerate the hull speed, so that the hull can reach the filling state at the fastest speed, which is suitable for emergency use needs; In the process of the connecting section between the hull and the air inlet cavity being rounded, the rounding member can drive the length direction of the elastic structure fixed rail arranged in the air inlet cavity to move toward the outside of the air inlet cavity, and then the elastic structure cooperates with the guide structure arranged in the air inlet cavity to drive the blocking ring arranged in the air inlet cavity to block the air inlet window, so that the gas pumped by the air pump can all enter the hull, thereby accelerating the forming speed of the hull; At the same time, during the blocking process of the blocking ring, the triggering member arranged on the blocking ring can drive the two sets of baffles arranged in the air intake cavity and placed in front of the impeller to deflect in the opposite direction. The deflected baffles can shield the driving structure, thereby reducing the impact resistance of the high-speed gas in the air intake cavity, thereby accelerating the inflation speed of the hull; In particular, a deflation component is also provided on the air inlet cavity. When the hull is deflated, the inflation port is opened and the hull is pressed. The reverse action of the driving structure can drive the supporting round member back to the initial position, and the unlocking rod is pulled outward at the same time. During the pulling process, the unlocking rod can force the elastic structure to move in the opposite direction along the fixed rail, and with the cooperation of the guide structure, the elastic structure can pull the sealing ring and the baffle back to the initial position. At this time, the gas in the hull can leak outward through the air inlet window and the inflation port. Compared with the leakage method of a single inflation port, the deflation speed is faster and it is easier to store. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0029] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0030] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0031] See also Figure 1-Figure 11 In an embodiment of the present invention, an airdrop inflatable boat includes: A hull 1, wherein an air inlet cavity 2 is provided on the hull 1, and an air inlet window 201 is provided on the air inlet cavity 2. An air pump is connected to the air inlet cavity 2 to inflate the hull 1; Preferably, the hull 1 is made of rubber material. When not in use, the rubber hull 1 can be folded or rolled up after the gas in the hull 1 is exhausted, so that the volume of the hull 1 can be reduced, thereby facilitating storage. When it is needed, sufficient gas is filled into the hull 1, so that the hull 1 can be formed into an inflatable boat with greater buoyancy. At this time, the hull 1 can float on the water surface, so that the user can play on the water surface or perform rescue operations. In particular, the air inlet cavity 2 is a rigid structure that can maintain a cylindrical state and is not easily deformed. Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a plurality of groups of air inlet windows 201 are equidistantly provided on the outer wall of the air inlet cavity 2, and an air charging port 202 is provided on the air inlet cavity 2, and the air charging port 202 can be connected to an air pump. Driven by the air pump, the hull 1 can be inflated or deflated through the air charging port 202 according to actual use requirements, thereby facilitating the subsequent use or storage of the hull 1.

[0032] A rounding component is arranged in the air inlet chamber 2, and the rounding component includes a driving structure and a rounding member. The rounding member is arranged in at least three groups equidistantly along the circumferential direction of the air inlet chamber 2. When the air pump pumps air into the air inlet chamber 2, the driving structure is actuated to drive the rounding member to expand outward, thereby expanding the hull 1 near the connection with the air inlet chamber 2, thereby expanding the air inlet channel of the hull 1, and in the process of the hull 1 being expanded, air can be sucked into the interior through the air inlet window 201 at the same time, thereby accelerating the inflation speed; The driving structure comprises an impeller 16 rotatably mounted in the air inlet chamber 2, a screw rod 5 is coaxially fixedly arranged on the impeller 16, and a threaded sleeve 10 threadedly connected thereto is arranged on the screw rod 5; The round support member includes a support plate 4, and at least three groups of the support plates 4 are equidistantly arranged along the circumferential direction of the screw rod 5, and each group of the support plates 4 is connected to the threaded sleeve 10 through a hinge rod 20, and the support plates 4 are connected to a guide member arranged in the air inlet cavity 2; Preferably, see Figure 3 , Figure 4 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11The above-mentioned round support member is equidistantly arranged in four groups along the axial direction of the screw rod 5, and the impeller 16 is close to the inflation port 202. The screw rod 5 is placed in the hull 1 connected to the air inlet chamber 2. In the initial state, the above-mentioned threaded sleeve 10 is away from the impeller 16. At this time, the four groups of support plates 4 are close to the threaded sleeve 10. When the air pump is connected to the air inlet chamber 2 and pumps air into the air inlet chamber 2, the high-speed flowing gas collides with the blades of the impeller 16, which can drive the impeller 16 to rotate continuously in the same direction. Then, the impeller 16 that rotates continuously in the same direction can drive the screw rod 5 to rotate. At this time, under the cooperation between the guide member and the support plate 4, the threaded sleeve 10 can only move toward the impeller 16 along the axial direction of the screw rod 5. In this process, Due to the connecting action of the fixed-length hinged rod 20, the threaded sleeve 10 approaching the impeller 16 can push the four groups of support plates 4 to expand outward, and can round the connecting section between the hull 1 and the air inlet chamber 2, thereby widening the air inlet channel of the rubber part of the hull 1. Subsequently, the gas entering the hull 1 through the inflation port 202 of the air inlet chamber 2 can be quickly filled into various areas of the hull 1, and in the process of the support plate 4 performing the rounding, the expansion of the hull 1 can cause negative pressure in the airbag section. At this time, the negative pressure generated inside the hull 1 can suck external gas into the hull 1 through the air inlet window 201, and then can further accelerate the inflation speed of the hull 1, so that the hull 1 can be filled to a usable state in the shortest time.

[0033] For details, please refer to Figure 4 , Figure 7 , Fig. 9 , Fig.11 The guide member includes a fixed frame 21 fixedly arranged in the air inlet cavity 2, the screw rod 5 passes through the fixed frame 21, and the fixed frame 21 is fixedly provided with at least three groups of support rods 6 equidistantly along its circumferential direction, and the support rods 6 are provided with a moving groove 601, and the support plate 4 is slidably arranged in the moving groove 601; Correspondingly, the support rod 6 is equidistantly arranged in four groups around the circumferential direction of the screw rod 5, and the four groups of support plates 4 are fixedly provided with a T-block 401 at one end facing the fixed frame 21, and the T-block 401 is slidably arranged in the movable groove 601. Under the cooperation of the T-block 401 and the movable groove 601, the support plate 4 can only slide along the length direction of the support rod 6; In combination with the above, in the initial state, the T-block 401 is close to the screw 5. When the impeller 16 is rotated by the impact of the high-speed airflow, the screw 5 can drive the threaded sleeve 10 to approach the impeller 16. In this process, due to the connecting action of the fixed-length hinged rod 20, the support plate 4 retracted inside can expand outward to open the hull 1 connected to the air inlet chamber 2, thereby increasing the inflation speed and facilitating the rapid inflation and molding of the hull 1 to meet emergency use needs.

[0034] For further information, see Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 The air inlet cavity 2 is also provided with a baffle assembly, which is connected to the round support member through a trigger assembly. When the round support member is actuated, the trigger assembly can drive the baffle assembly to baffle the air inlet window 201 and the driving structure, thereby increasing the flow speed of the gas; The trigger assembly includes an elastic structure and a guide structure, the elastic structure includes a fixed rail 15 arranged in the air inlet cavity 2, a plug-in cylinder 14 is slidably arranged in the fixed rail 15, a first spring 13 is slidably arranged in the plug-in cylinder 14, one end of the first spring 13 abuts against the plug-in cylinder 14, and the other end abuts against a plug-in rod 12 slidably arranged in the plug-in cylinder 14, a pulley 1201 is installed at one end of the plug-in rod 12 away from the fixed rail 15, and the plug-in rod 12 is connected to a blocking ring 8 slidably arranged in the air inlet cavity 2; For details, please refer to Figure 4 , Figure 5 , Figure 6 The outer diameter of the blocking ring 8 is the same as the inner diameter of the air inlet chamber 2, and two groups of clamping blocks 801 are fixedly arranged at equal intervals along the circumferential direction of the outer wall of the blocking ring 8. The clamping blocks 801 are slidably arranged in the clamping grooves 203 provided on the inner wall of the air inlet chamber 2. Under the cooperation between the clamping blocks 801 and the clamping grooves 203, the blocking ring 8 can only move along the axial direction of the air inlet chamber 2. In detail, the above-mentioned plug-in cylinder 14 is fixedly connected to the I-shaped piece 1401 slidably arranged in the fixed rail 15, and the above-mentioned blocking ring 8 is fixedly provided with a connecting rod 22, and the connecting rod 22 is provided with a guide groove 2201, and a sliding rod is arranged in the guide groove 2201, and the sliding rod is fixedly connected to the plug-in rod 12. In particular, the above-mentioned first spring 13 is always in a compressed state, and the first spring 13 in the compressed state pushes the plug-in rod 12 to have a tendency to move away from the fixed rail 15. In the initial state, the pulley 1201 is located at the first inclined rail 1101 away from the second inclined rail 1 At the end of the stroke of 102, when the support plates 4 are expanded outward, the second trigger rod 19 (in an "L"-shaped structure) fixedly arranged on one group of support plates 4 can pull the I-shaped piece 1401 to move along the through groove 1501 toward the second inclined rail 1102. During this process, the plug-in rod 12 cooperates with the guide structure to force the sealing ring 8 to move quickly toward the impeller 16, thereby sealing the air intake window 201, so that after the subsequent connecting end of the hull 1 and the air intake chamber 2 is rounded, the gas pumped into the air intake chamber 2 by the air pump can all enter the hull 1, thereby accelerating the inflation speed of the hull 1.

[0035] For details, please refer to Figure 6 The guide structure includes a slide rail 11 fixedly arranged in the air inlet cavity 2, and the pulley 1201 is slidably arranged in the slide rail 11. When the plug-in cylinder 14 slides relative to the fixed rail 15, the pulley 1201 cooperates with the slide rail 11 to drive the blocking ring 8 to move quickly along the axial direction of the air inlet cavity 2, thereby blocking the air inlet window 201; The slide rail 11 includes a first inclined rail 1101 and a second inclined rail 1102, wherein the second inclined rail 1102 is longer than the first inclined rail 1101, and the end of the second inclined rail 1102 is higher than the end of the first inclined rail 1101 (such as Figure 6 shown); In combination with the above, in the initial state, the pulley 1201 is located at the end of the travel of the first inclined rail 1101 away from the second inclined rail 1102. At this time, the sealing ring 8 is not in contact with the air inlet window 201. When the air pump is connected to the inflation port 202 to pump air into the hull 1, the impeller 16 can drive the screw 5 to rotate under the impact of the high-speed gas, and then the screw 5 can drive the threaded sleeve 10 to approach the impeller 16. In this process, the support plate 4 slides along the movable groove 601, which can round the connection between the hull 1 and the air inlet cavity 2. At the same time, the first The second trigger rod 19 can push the I-shaped part 1401 to drive the plug-in tube 14 and the plug-in rod 12 to move along the length direction of the fixed rail 15 toward the second inclined rail 1102. During the movement, the slide bar on the plug-in rod 12 can slide in the guide groove 2201, and when the plug-in rod 12 slides, the contact and extrusion of the inner wall of the first inclined rail 1101 on the pulley 1201 can force the plug-in rod 12 to move toward the inside of the plug-in tube 14, thereby further squeezing the first spring 13. At this time, the plug-in rod 12 can drive the blocking ring 8 to move a distance away from the impeller 16; When the support plate 4 moves to the end of the travel of the moving groove 601, under the cooperation of the screw rod 5 and the threaded sleeve 10, the impact generated by the impeller 16 will not be able to drive the impeller 16 to rotate. At this time, the position of the support plate 4 is locked. At the same time, the second trigger rod 19 fixedly connected to the support plate 4 can just push the pulley 1201 on the plug-in rod 12 to cross the connection between the first inclined rail 1101 and the second inclined rail 1102, and combine with the second inclined rail 1102. At this time, the first spring 13 releases the elastic potential energy to quickly push the pulley 1201 to drive the plug-in rod 12 and the plug-in tube 14 to slide along the second inclined rail 1102 until the pulley 1201 comes to the second inclined rail 1102 away from the first inclined rail 1101. During the process, the plug-in rod 12 moves away from the fixed rail 15 and drives the blocking ring 8 to move toward the impeller 16 (because the distance between the end of the second inclined rail 1102 and the fixed rail 15 is greater than the distance between the end of the first inclined rail 1101 and the fixed rail 15, the distance the blocking ring 8 moves toward the impeller 16 is much greater than the distance the blocking ring 8 moves away from the impeller 16), so that the blocking ring 8 can block the air inlet window 201, and in the process of the blocking ring 8 blocking the air inlet window 201, the barrier assembly is triggered to block the impeller 16 to reduce the impact of the airflow with the blades of the impeller 16, thereby accelerating the flow speed of the gas in the hull 1 so that the hull 1 can be quickly formed.

[0036] For details, please refer to Figure 4 , Figure 5 , Figure 6 The baffle assembly includes a baffle 7 rotatably mounted in the air inlet cavity 2. The baffle 7 is symmetrically arranged in two groups along the length direction of the fixed rail 15. A slide groove 701 is opened on the side of each group of baffles 7. The slide groove 701 is driven by a trigger member arranged on the blocking ring 8 and can be deflected relative to the air inlet cavity 2, thereby shielding the impeller 16. The trigger member comprises a trigger plate 9 fixedly arranged on the blocking ring 8, and two groups of the trigger plates 9 are symmetrically arranged along the length direction of the baffle plate 7, and each group of the trigger plates 9 is fixedly provided with two groups of protruding columns 901, and the protruding columns 901 are correspondingly slidably arranged in the sliding groove 701; In combination with the above, in the initial state, the protruding column 901 is located in the sliding groove 701. When the blocking ring 8 is away from the impeller 16, the protruding column 901 moves toward the impeller 16 along the sliding groove 701, which can drive the two sets of baffles 7 to approach each other. At this time, the amount of air entering the air inlet chamber 2 through the inflation port 202 and colliding with the blades of the impeller 16 increases, which can increase the rotation speed of the impeller 16, and then increase the speed of the support plate 4 to expand. When the support plate 4 is expanded, the plug rod 12, which is automatically and quickly driven by the guide structure and the first spring 13 to keep moving in the same direction, can drive the blocking ring 8 to quickly expand. During this process, the contact and compression of the protruding column 901 on the wall of the slide groove 701 can force the two groups of baffles 7 to deflect away from each other until the sealing ring 8 completely covers the air inlet window 201 and is in a stable state. The two groups of baffles 7 can just cover the impeller 16. At this time, the gas entering the air inlet chamber 2 from the inflation port 202 can, under the guidance of the baffle 7, pass through the impeller 16 and enter the hull 1. By setting the baffle 7, the impact resistance of the gas in the air inlet chamber 2 can be reduced, thereby maintaining the flow speed of the gas and making the inflation speed faster.

[0037] For further information, see Figure 4 , Figure 7 , Figure 8 , the air inlet chamber 2 is also provided with an air release component, the air release component includes an unlocking rod 3 which is sealingly and slidably provided in the air inlet chamber 2, one end of the unlocking rod 3 which is immersed in the air inlet chamber 2 is fixedly provided with a first triggering rod 18, and the other end is fixedly provided with a positioning block 302, and a second spring 17 is also slidably provided on the unlocking rod 3, one end of the second spring 17 abuts against the first triggering rod 18, and the other end abuts against the inner wall of the air inlet chamber 2; Preferably, the first trigger lever 18 is configured as follows: Figure 8 The unlocking rod 3 has an L-shaped structure, and two groups of grooves 301 are equidistantly formed along its circumferential direction, and the grooves 301 are adapted to the protrusions formed on the wall of the air inlet cavity 2, so that the unlocking rod 3 can only slide along the length direction of the fixed rail 15; In particular, the second spring 17 is in a compressed state. In the initial state, the second spring 17 in the compressed state can make the positioning block 302 fit tightly with the air inlet chamber 2, and at the same time make the first trigger rod 18 away from the plug-in rod 12. When the air inlet window 201 is blocked, the I-shaped piece 1401 is close to the first trigger rod 18. Until the hull 1 is filled and formed, the state between the I-shaped piece 1401 and the first trigger rod 18 remains unchanged. When the hull 1 needs to be folded after use, first find the pull ring 303 on the positioning block 302, then open the inflation port 202, and squeeze the hull 1. Then, hold the The pull ring 303 pulls the unlocking rod 3 outward, and the first trigger rod 18 can contact the I-shaped part 1401 and drive the I-shaped part 1401 toward the screw rod 5. During this process, due to the cooperation of the first spring 13, the sealing ring 8 and the baffle 7 can be restored to their initial state. At the same time, the impeller 16 rotates in the opposite direction, which can drive the support plate 4 back to the initial position. Then the pull ring 303 is released, and the unlocking rod 3 can return to the initial state driven by the second spring 17. At this time, the gas in the hull 1 can leak outward from the air inlet 201 and the inflation port 202, and the speed is faster than the deflation of the single inflation port 202.

[0038] An airdrop inflatable boat and an intelligent inflation method are also proposed. The airdrop inflatable boat as described above is used, and the steps are as follows: Step 1: Connect the air pump to the air inlet chamber 2, then start the air pump, and the airflow pumped into the air inlet chamber 2 forces the impeller 16 to rotate. Then, the screw 5 drives the threaded sleeve 10 to approach the impeller 16. At this time, with the cooperation of the guide member, the support plate 4 expands outward, which can open the hull 1 that is wrinkled together, thereby widening the air inlet channel; Step 2: During the expansion process, the support plate 4 can drive the elastic structure to gradually move away from the axis of the air inlet cavity 2. When the support plate 4 is expanded to the maximum, the elastic structure automatically moves quickly toward the impeller 16, thereby driving the blocking ring 8 to block the air inlet window 201. Step three: During the movement of the sealing ring 8 toward the impeller 16, the trigger member arranged on the sealing ring 8 can drive the two sets of baffles 7 to move away from each other, thereby shielding the impeller 16 to reduce the resistance encountered by the gas in the air inlet chamber 2 during the pumping process, thereby accelerating the inflation speed, and after the gas in the hull 1 is sufficient, remove the air pump.
