Description

Technical Field

[0001] This utility model relates to the field of venting pipe technology, specifically to a venting pipe device for rapid venting of an inflatable trampoline. Background Technology

[0002] Inflatable trampolines and other inflatable amusement facilities are widely used in children's playgrounds, outdoor activity areas, and commercial performances. These products are usually made of materials such as Oxford cloth, and their structure is not airtight. They rely on blowers to continuously send air into the trampoline to maintain a positive pressure inside, thereby supporting the overall shape.

[0003] However, currently, after the use of such inflatable amusement facilities, the main method for releasing residual gas is manual squeezing to achieve storage. Specifically, the blower is first turned off to stop air supply, and then the operator manually folds, steps on, or presses the surface of the trampoline to force the internal air to slowly escape from the air supply interface or structural gaps. This process is not only labor-intensive and time-consuming, but if the gas is not completely expelled, the rolled-up volume is easily too large, making it difficult to pack into a storage bag, resulting in a loose and messy appearance, affecting the convenience of transportation and the subsequent user experience. At the same time, under the high-frequency deployment and retrieval requirements of inflatable amusement facilities in commercial operation, the current venting method is inefficient and may also pose safety hazards due to improper operation. Utility Model Content

[0004] The purpose of this invention is to provide a deflation pipe device for quickly deflating an inflatable trampoline, thereby solving the problems of high labor intensity and long time consumption caused by manually squeezing out residual gas for storage.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a deflation pipe device for rapid deflation of an inflatable trampoline, wherein the inflatable trampoline has an air supply pipe communicating with its inner cavity, the air supply pipe being used to connect to the air outlet of a blower, the deflation pipe device including a mounting cover for cooperating with the blower, a flexible connecting pipe that can be bent and deformed, and a deflation pipe assembly that can be inserted into the air supply pipe, the three being connected in sequence and internally interconnected to form an airflow channel, the mounting cover being provided with a cooperating structure that can be detachably connected to the air inlet of the blower so that the air inlet of the blower can be connected to the airflow channel.

[0006] As a further optimization of this utility model, the mating structure includes an air intake chamber opened on the mounting cover and a connecting ring located at the opening of the air intake chamber and able to surround the air inlet end of the blower after being attached to the blower.

[0007] As a further optimization of this utility model, the inner wall of the connecting ring is provided with an elastic protruding ring extending circumferentially.

[0008] As a further optimization of this utility model, the mounting cover is an integral structure made of soft material.

[0009] As a further optimization of this utility model, the venting pipe assembly includes a sleeve structure consisting of at least two pipe sections that can be slidably sleeved together.

[0010] As a further optimization of this utility model, multiple air intake holes are provided through the side wall of each tube, and the air intake holes are distributed in an array on each tube.

[0011] As a further optimization of this utility model, the venting pipe assembly includes a first venting pipe, a second venting pipe, and a third venting pipe that can be slidably sleeved together.

[0012] As a further optimization of this utility model, the inner wall of the upper part of the first vent pipe is provided with a first limiting protrusion, the outer wall of the lower part of the second vent pipe is provided with a second limiting protrusion that can cooperate with the first limiting protrusion to restrict the second vent pipe from sliding upward, the inner wall of the upper part of the second vent pipe is provided with a third limiting protrusion, and the outer wall of the lower part of the third vent pipe is provided with a fourth limiting protrusion that can cooperate with the third limiting protrusion to restrict the third vent pipe from sliding upward.

By connecting the mounting cover to the air inlet of the blower and inserting the air release pipe assembly into the air supply pipe of the trampoline, the blower can draw air from inside the trampoline through the airflow channel.

[0022] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figures 1 to 6 As shown, this utility model discloses a deflation pipe device for rapid deflation of an inflatable trampoline. The inflatable trampoline has an air supply pipe communicating with its inner cavity. The air supply pipe is used to connect to the air outlet of a blower. The deflation pipe device includes a mounting cover 1 for connecting with the blower, a flexible connecting pipe 2 that can be bent and deformed, and a deflation pipe assembly 3 that can be inserted into the air supply pipe. The three are connected in sequence and internally connected to form an airflow channel 4. The mounting cover 1 is provided with a mating structure 11 that can be detachably connected to the air inlet of the blower so that the air inlet of the blower can communicate with the airflow channel 4.

[0024] The mounting cover 1, through its mating structure 11, matches the air inlet of a common air blower, thereby connecting the blower's air inlet to the airflow channel 4. The flexible connecting pipe 2 connects the mounting cover 1 to the venting pipe assembly 3, forming the middle section of the airflow channel 4. The flexible connecting pipe 2's bending deformation allows the venting pipe assembly 3 to be adjusted in position. The venting pipe assembly 3 can be inserted into the existing air supply pipe of the inflatable trampoline, extending the airflow channel 4 into the trampoline's internal cavity, enabling the blower to draw air from within. In this embodiment, the mounting cover 1, the flexible connecting pipe 2, and the venting pipe assembly 3 are all independent, detachable components, facilitating storage and reuse.

[0025] The usage of this utility model is as follows: After the inflatable trampoline is used, first turn off the blower supplying air to it and disconnect the connection between the blower outlet and the air supply pipe of the inflatable trampoline, so that the trampoline stops taking in air and prepares to enter the deflation stage. Then, connect the mounting cover 1 of this deflation pipe device to the air inlet of the blower, and insert the deflation pipe assembly 3 at the other end of the deflation pipe device into the air supply pipe of the inflatable trampoline. Then restart the blower. At this time, a negative pressure is generated at the air inlet of the blower, and air enters the air inlet of the blower from inside the trampoline through the airflow channel 4, and is discharged to the external environment from the air outlet of the blower. During the deflation process, as the volume of the trampoline gradually shrinks, the bending shape of the flexible connecting pipe 2 can be manually adjusted to adjust the insertion position of the deflation pipe assembly 3, promoting the effective discharge of residual gas in different areas. When the gas inside the trampoline is basically discharged, turn off the blower, pull the deflation pipe assembly 3 out of the air supply pipe of the trampoline, and remove the mounting cover 1 from the air inlet of the blower, thus completing the use.

[0026] This device fully utilizes a blower used in conjunction with inflatable amusement facilities such as inflatable trampolines for venting. It eliminates the need for additional air source equipment or new structures such as air nozzles or vent valves on Oxford cloth products, making it fully compatible with existing products. By connecting the mounting cover 1 to the air inlet of the blower and inserting the venting pipe assembly 3 into the air supply pipe of the trampoline, the blower can draw air from inside the trampoline through the airflow channel 4. Compared to traditional venting methods that rely on manual squeezing, stepping, or folding, this device significantly reduces labor intensity, increases venting speed and storage efficiency, and effectively solves the technical problem of low venting efficiency of inflatable trampolines.

[0027] The mating structure 11 includes an air intake chamber 12 formed on the mounting cover 1 and a connecting ring 13 located at the opening of the air intake chamber 12 and able to surround the air inlet end of the blower after being attached to the blower.

[0028] In this embodiment, the air intake chamber 12 is the inlet section of the airflow channel 4. The connecting ring 13 is disposed at the edge of the opening end of the air intake chamber 12, that is, on the side where the mounting cover 1 contacts the blower. The connecting ring 13 can surround and fit the outer peripheral wall or end face edge of the blower's air inlet end to prevent the mounting cover from slipping off.

[0029] The inner wall of the connecting ring 13 is provided with an elastic protruding ring 131 extending circumferentially.

[0030] The elastic protruding ring 131 is preferably a silicone ring, which is disposed on the inner sidewall surface of the connecting ring 13 and extends continuously and in a closed manner along the circumference to form a ring-shaped protrusion. When the connecting ring 13 is set around the air inlet end of the blower after being attached to the blower, the deformed elastic protruding ring 131 tightly fits the outer wall of the air inlet end of the blower to form an interference fit seal, ensuring air extraction efficiency.

[0031] The mounting cover 1 is a one-piece structure made of soft material.

[0032] Mounting cover 1 is made of a single piece of soft material. Its self-adaptive nature allows it to accommodate various fan inlets of similar diameters, improving product versatility. Simultaneously, the soft material acts as a buffer against the slight vibrations generated during blower operation, preventing loosening or wear caused by rigid connections and enhancing connection stability.

[0033] The matching structure 11 can also be achieved in other ways, such as by setting cable ties on the soft mounting cover 1, and adjusting the tightness of the cable ties to ensure that the mounting cover 1 does not come loose when connected to the air inlet of the blower.

[0034] The venting pipe assembly 3 includes a sleeve structure consisting of at least two tube bodies 31 that can be slidably sleeved together.

[0035] In this embodiment, the tube body 31 is preferably made of a flexible but supportive material such as nylon mesh tubing or PU-coated steel wire hose. The sleeve structure allows the venting tube assembly 3 to extend into the main internal cavity of the product. The sleeve structure, consisting of at least two relatively slidable tube bodies 31, allows the venting tube assembly 3 to dynamically adjust its insertion depth and coverage area when venting large inflatable trampolines in designated areas, improving venting efficiency and operational flexibility.

[0036] Multiple air intake holes 32 are provided through the side wall of each tube body 31, and the air intake holes 32 are arranged in an array on each tube body 31.

[0037] In this embodiment, the diameter of the suction holes 32 is 8–15 mm, and the axial spacing of each group of suction holes 32 is 10–15 cm. Simultaneously, the outer openings of the suction holes 32 are chamfered to avoid scratching the Oxford cloth. The number and density of the holes can be adjusted according to the internal dimensions of the product to ensure overall uniformity of air extraction. Compared to relying solely on the port of the tube 31 for air intake, the suction holes on the sidewall of the tube 31 allow gas to enter simultaneously from multiple locations along the entire length of the tube, significantly expanding the effective air intake area and improving extraction efficiency.

[0038] The venting pipe assembly 3 includes a first venting pipe 311, a second venting pipe 312, and a third venting pipe 313 that can be slidably sleeved together.

[0039] The three-stage telescopic sleeve structure provides a wider range of telescopic adjustment and stronger spatial adaptability.

[0040] The inner wall of the upper part of the first vent pipe 311 is provided with a first limiting protrusion 3111, the outer wall of the lower part of the second vent pipe 312 is provided with a second limiting protrusion 3121 that can cooperate with the first limiting protrusion 3111 to restrict the second vent pipe 312 from sliding upward, the inner wall of the upper part of the second vent pipe 312 is provided with a third limiting protrusion 3122, and the outer wall of the lower part of the third vent pipe 313 is provided with a fourth limiting protrusion 3131 that can cooperate with the third limiting protrusion 3122 to restrict the third vent pipe 313 from sliding upward.

[0041] When the second vent pipe 312 slides upward to its maximum stroke, its second limiting protrusion 3121 abuts against the lower part of the first limiting protrusion 3111, forming an axial stop to prevent the second vent pipe 312 from completely dislodging from the first vent pipe 311; at the same time, when the third vent pipe 313 slides upward to its maximum extension position, its fourth limiting protrusion 3131 abuts against the lower part of the third limiting protrusion 3122, achieving axial limiting and preventing the third vent pipe 313 from dislodging from the second vent pipe 312.

[0042] The inner wall of the lower part of the first vent pipe 311 is provided with a fifth limiting protrusion 3112 that can restrict the second vent pipe 312 from sliding down, and the inner wall of the lower part of the second vent pipe 312 is provided with a sixth limiting protrusion 3123 that can restrict the third vent pipe 313 from sliding down.

[0043] By using the fifth limiting protrusion 3112 and the sixth limiting protrusion 3123, which respectively act on the axial limiting of the second vent pipe 312 and the third vent pipe 313 when they are in the fully retracted position, the pipe body 31 is prevented from falling off due to shaking, inversion or transportation.

[0044] The structure of mutually cooperating limiting protrusions enables progressive sliding guidance and end position limiting, ensuring structural stability and reliable operation.

[0045] The flexible connecting pipe 2 is a corrugated pipe.

[0046] A corrugated pipe refers to a tubular component with a continuous annular or spiral pleated structure, which has good radial bending performance. When the deflation pipe assembly 3 deflates the inflatable trampoline, the position of the deflation pipe assembly 3 can be adjusted by the bending of the corrugated pipe itself, improving ease of use.

[0047] This invention is applicable to most inflatable amusement facilities that rely on constant pressure from a blower to maintain their shape, such as inflatable trampolines, inflatable slides, and inflatable castles. By reusing the original blower of the equipment to achieve active air extraction, it significantly improves folding efficiency. This solution has broad application value and good practicality in high-frequency setup and dismantling scenarios for commercial rental companies, storage of household inflatable facilities, daily operation and maintenance of parks and playgrounds, and pop-up events such as exhibitions and promotions.
