Description

Technical Field

[0001] This invention relates to the field of inflatable tent technology, specifically to a quick-inflating outdoor tent. Background Technology

[0002] Existing quick-inflating outdoor tents have abandoned the traditional metal frames. The main body of the tent is composed of high-strength waterproof fabric and built-in PVC inflatable beams. Using the provided electric air pump or manual air pump, the inflatable beams can be inflated and formed in minutes, making the setup process convenient and efficient. With ground pegs and windproof ropes at the bottom, it can stably support various terrains such as mountains and grasslands, making it suitable for camping, outdoor gatherings and other scenarios. When stored, it deflates and folds into a compact size, making it easy to carry and transport, providing a comfortable and sheltered space for quick setup when going outdoors.

[0003] However, existing technologies still have the following drawbacks in practical applications: 1. Compared to existing inflatable tents, which generally use a single air column inflation method, with a single air channel running through all the support parts of the tent, this method, while convenient in production, ignores the complexity of outdoor equipment in actual use scenarios. During tent setup, the need to adapt to different terrains, bends, corners, and the three-dimensional structure designed to achieve diverse spatial layouts make it difficult for a single air column to deliver gas evenly. Furthermore, when the gas flows along a single path, it has to change direction when it encounters bends such as tent corners, resulting in a sharp decrease in flow velocity. Some gas may even form vortices, creating significant air resistance. This not only greatly prolongs inflation time and reduces the camper's setup efficiency, but may also cause uneven stress on the tent support frame due to local air pressure imbalance, leading to tent tilting and deformation, severely weakening its wind and rain protection performance. More seriously, the bends of the air column, which are under high pressure differential for a long time, are prone to material fatigue and damage, causing air leaks or even structural breakage, endangering the user's safety and greatly affecting the tent's durability and reliability.

[0004] 2. Compared to existing inflatable tents, although the inflatable beams can be expanded and formed in a few minutes using the provided electric air pump or manual air pump, in order to ensure that the subsequent air columns can be evenly inflated and formed, the tent needs to be kept in a stretched state before inflation. However, in actual operation, it is difficult for users to completely eliminate the situation of tent folding and local pressure. Furthermore, from the perspective of production and transportation, folded tents are easier to store and transport, which makes it difficult to avoid the step of flattening before inflation in the design. In addition, due to the limitation of the single air column inflation path, the gas flows according to the principle of "path of least resistance", resulting in local differences during inflation. The defects caused by this inflation method will seriously affect the user experience and safety of the tent. Whether it is local expansion or local depression of the air column, it will cause the overall structure of the tent to become unbalanced, thus affecting the tent's forming efficiency. At the same time, local over-expansion will cause the air column material to be subjected to excessive pressure, accelerating the aging and damage of the air column and shortening the tent's lifespan. In addition, uneven inflation will prevent the tent from unfolding properly, requiring users to repeatedly adjust and re-inflate, wasting time and energy, reducing the efficiency and convenience of outdoor setup, and greatly diminishing the original advantage of inflatable tents being quick to set up.

[0005] Therefore, in view of this, the present invention proposes a quick-inflation support outdoor tent to make up for and improve the shortcomings of the prior art. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a quick-inflation support outdoor tent, thereby resolving the technical issues raised in the background section.

[0007] To achieve the above objectives, the technical solution adopted by this invention is as follows: a fast-inflating outdoor tent, comprising an inflatable base pad, an air column frame mounted on top of the inflatable base pad, a tent fabric mounted on the outside of the air column frame, and a fast-charging component inside the inflatable base pad. The fast-charging component includes a main air column, a spacer ring, and a connecting pipe. The spacer ring divides the interior of the main air column into multiple air passages. Both the spacer ring and the connecting pipe are located at the center of the inflatable base pad. This outdoor tent adopts a slow-to-fast inflation method. In the low-speed inflation state, the airflow output from the external air source is concentrated inside the spacer ring, relying on the flowing airflow for support. After the bottom inflatable base pad is initially formed, it is easy to adjust the folds of the tent fabric. Secondly, during the low-speed inflation process, tent pegs can be installed more reasonably according to the specific footprint and distribution of the bottom after it is formed. After the inflatable base pad is formed, the system switches to a high-speed inflation state. The airflow output from the external air source flows throughout the main air column, reducing gas flow deviation and allowing the air column frame to inflate evenly to support the tent fabric.

[0008] Furthermore, the input end of the main air column extends to the outside of the inflatable base pad, a central shaft is fixedly connected inside the main air column, and a threaded track is fixedly connected to the outer wall of the central shaft.

[0009] Furthermore, a vortex element is installed on the outer wall of the central shaft near the main air column input end. The vortex element is composed of several fan-shaped blades, and the fan-shaped blades are all inclined and fixedly connected to the central shaft.

[0010] Furthermore, a conversion adjustment plate is rotatably connected to the side wall of the main air column, and a spacer ring is fixedly connected to the inner wall of the conversion adjustment plate. The spacer ring is cylindrical in shape, and a perforated groove is evenly opened on the outer wall of the spacer ring.

[0011] Furthermore, the surface of the conversion plate is uniformly perforated with vent holes, and the side wall of the conversion plate is uniformly rotatably connected with a connecting pipe. In the initial state, the vent holes and the connecting pipe are staggered, and at this time, the external air source can only input airflow into the main air column through the spacer ring.

[0012] Furthermore, after the conversion adjustment plate is rotated 45 degrees clockwise, the vent hole and the connecting pipe are aligned, and at this time, the external air source can input airflow into the main air column through the spacer ring and the connecting pipe.

[0013] Furthermore, the connecting pipe is located at the interval between the main air column and the spacer ring, and after the conversion adjustment plate is rotated forty-five degrees, the grooves opened on the outer wall of the spacer ring correspond to the connecting pipe.

[0014] Furthermore, the output end of the main air column is connected to a steering cylinder, the output end of the main air column has a gradually narrowing funnel shape, and a flow divider is fixedly connected inside the steering cylinder. The flow divider has an isosceles triangle cross section, with its tip facing the output end of the main air column.

[0015] Furthermore, branch pipes are symmetrically connected to both sides of the steering cylinder. The branch pipes are L-shaped in general. Pressure valves are installed inside the vertical parts of the branch pipes, and flexible bending hoses are installed at the curved parts of the branch pipes. The flexible bending hoses are made of elastic material, have a smooth interior, and are reinforced with ribs on the outer wall. The flexible bending hoses adapt to airflows with different impact forces through their own elastic deformation.

[0016] Furthermore, a drainage plate is installed at the bending position of the curved hose, and the drainage plate is incompletely arc-shaped.

[0017] Compared with the prior art, the beneficial effects of the present invention are: (1) This device adopts a slow-then-fast inflation method, which breaks the limitation of the single-speed inflation of traditional inflatable tents. First, in the initial stage of inflation, a low-speed mode is adopted, and the gas flows in the spacer ring at a low flow rate. This slow and gentle inflation method allows the inflatable base to unfold slowly and evenly, avoiding the problem of wrinkles and accumulation caused by the instantaneous expansion of the tent structure due to excessive airflow. In addition, the user has enough time to flatten and adjust the surface of the tent, effectively reducing the tedious steps of secondary adjustment. Especially when setting up in complex terrain, low-speed inflation can also provide operating space for accurately positioning the tent. Under low-speed inflation, the bottom of the tent gradually takes shape, and its area and shape are clearly presented. The user can plan the installation position and density of the tent pegs more reasonably according to the actual unfolding situation, ensuring that the tent pegs can be evenly distributed and stressed, and enhancing the wind resistance and anchoring performance of the tent.

[0018] Once the inflatable base is initially formed, the system switches to high-speed inflation. At low speeds, because the air pressure hasn't reached the pressure valve threshold, the gas concentrates in the bottom area, ensuring the tent's stability. At high speeds, the increased air pressure causes the gas to rapidly diffuse throughout the entire air column frame, allowing the gas to simultaneously fill all parts of the tent via multiple paths. This effectively disperses airflow resistance and significantly reduces gas flow deviation caused by a single air path. Compared to existing technologies where air easily forms resistance at corners or narrow channels, leading to over-inflation in some areas and under-inflation in others, this method ensures that airflow reaches the top, side walls, and other corners of the tent even at high speeds, greatly improving inflation uniformity and efficiency. This results in a more regular overall tent shape, providing users with a more reliable and convenient experience.

[0019] (2) More importantly, this “low-speed-high-speed” segmented inflation does not prolong the inflation time. Instead, it allocates the time ratio of low-speed and high-speed inflation according to the actual usage while keeping the inflation time unchanged. Compared with the existing technology, this method deeply integrates the time for manual flattening and adjusting wrinkles before inflation with the low-speed inflation stage: During low-speed inflation, the gas flows in the interval ring cylinder at a low flow rate, slowly pushing the inflatable base pad to unfold. During this process, the user can simultaneously flatten the tarpaulin, transforming the originally independent “manual flattening stage” into a “parallel inflation + adjustment stage”. With the segmented inflation method, this part of the time is completely integrated into the inflation process. This reduces the overall setup time by 20% to 30%. After entering the high-speed inflation stage, the stable foundation formed by low-speed inflation is used to quickly fill the entire air column frame with high-speed gas. Since the precise positioning and force layout of the tent bottom have been completed in the low-speed stage, i.e., the tent pegs are installed properly, the gas can diffuse evenly in a state of no wrinkles and smooth air passage during high-speed inflation. Therefore, this method of "shaping at low speed first and then pressurizing at high speed" not only ensures the regularity of the tent structure, but also ensures that each air column is filled at the same time. The total inflation time is comparable to that of traditional technology, but significantly improves the convenience of setup and the quality of tent formation, achieving the optimization effect of "unchanged time and doubled efficiency".

[0020] (3) This device has a central shaft, a threaded track and a vortex component in the main air column, so that the airflow flows in a rotating manner. The rotating airflow is deflected towards the air column wall by centrifugal force. This pressure distribution can actively balance the pressure difference in corners, branches and other parts. At the right-angle corners commonly found in tents, traditional straight airflow is prone to pressure imbalance due to sudden changes in direction. However, the rotating airflow guides the gas in the high-pressure area to the low-pressure area by centrifugal force, greatly reducing the pressure difference between various parts and avoiding the accumulation of gas in local areas to form air resistance. This makes the airflow in the air column smoother and more unobstructed. Its stable vortex shape can ensure that the airflow evenly fills each branch cavity of the tent evenly, even during the high-speed inflation stage, avoiding local over-inflation or under-inflation.

[0021] The main air column outlet is designed as a gradually narrowing funnel shape, which increases the gas velocity and reduces the pressure before turning, avoiding airflow turbulence and energy loss caused by sudden changes in the outlet cross-sectional area. This ensures that the gas can enter the turning cylinder in a stable state. The isosceles triangular-shaped flow divider, with its tip facing the air column outlet, evenly divides the concentrated airflow into two streams, guiding them along the inclined sides of the turning cylinder wall. This prevents the airflow from directly impacting the cylinder wall and forming turbulence and local high-pressure areas. The combination of these two features ensures that the airflow remains uniform and stable after turning, thereby improving the inflation synchronization of various parts of the tent and avoiding local expansion or folding of the tent due to uneven airflow.

[0022] (4) During the actual inflation process, a flexible hose is introduced at the corner of the branch pipe. On the one hand, the flexible hose is made of elastic material and the outer wall is reinforced with ribs to enhance its pressure resistance, so that it can withstand the impact of high air pressure without breaking or deforming. At the same time, the flexible material can naturally stretch with the airflow during inflation, replacing the problem of rigid bending that is easy to occur in traditional rigid pipe fittings, and effectively avoiding material fatigue and damage caused by frequent folding and twisting. On the other hand, the flexible deformation capability of the hose can dynamically adapt to changes in airflow pressure. When the gas passes through the corner, the hose deforms according to the impact force of the airflow, expanding the cross-sectional area of ​​gas flow, reducing the collision loss caused by the sudden change of airflow direction, and greatly improving the airflow throughput, avoiding local under-inflation or over-inflation caused by air resistance.

[0023] Among them, a partially curved flow guide plate is installed at the bend of the hose. The partially curved shape fits the bend of the hose, allowing the gas flowing through the bend to smoothly turn along the curve, avoiding the airflow from directly hitting the pipe wall and causing turbulence. This allows the gas to flow in an orderly manner and reduces the local high-pressure and low-pressure areas caused by sudden changes in flow direction. In addition, the flow guide plate can make the airflow velocity distribution at the bend more uniform, reducing the difference between high-speed and low-speed areas. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention. It should be noted that the structure and working principle of the above-mentioned inflatable base pad 1, air column frame 11, tarpaulin 12 and other devices are existing technologies and will not be described in detail here.

[0027] Example 1: Please refer to Figures 1-11 As shown, a quick-inflating outdoor tent includes an inflatable base pad 1, an air column frame 11 mounted on top of the inflatable base pad 1, a tent fabric 12 mounted on the outside of the air column frame 11, and a fast-charging component 2 disposed inside the inflatable base pad 1. The fast-charging component 2 includes a main air column 21, a spacer ring 26, and a connecting pipe 28. The spacer ring 26 divides the interior of the main air column 21 into multiple air passages. The spacer ring 26 and the connecting pipe 28 are both located at the center of the inflatable base pad 1. This outdoor tent uses a slow-to-fast inflation method. In the low-speed inflation state, the airflow from the external air source is concentrated inside the spacer ring 26. Relying on the flowing airflow as support, the bottom inflation pad 1 is initially formed, which facilitates the adjustment of the tent fabric 12 folds. Secondly, during the low-speed inflation process, tent pegs can be installed more reasonably according to the specific area and distribution after the bottom is formed. After the inflation pad 1 is formed, the system switches to high-speed inflation. The airflow from the external air source flows inside the entire main air column 21, reducing gas flow deviation and allowing all parts of the air column frame 11 to inflate evenly and support the tent fabric 12.

[0028] Please refer to Figures 1-11 As shown, It should be noted that the input end of the main air column 21 extends to the outside of the inflatable base pad 1. A central shaft 22 is fixedly connected inside the main air column 21, and a threaded track 23 is fixedly connected to the outer wall of the central shaft 22. A vortex element 24 is installed on the outer wall of the central shaft 22 near the input end of the main air column 21. The vortex element 24 is composed of several fan-shaped plates, and the fan-shaped plates are all inclined and fixedly connected to the central shaft 22. A conversion adjustment plate 25 is rotatably connected to the side wall of the main air column 21. A spacer ring 26 is fixedly connected to the inner wall of the conversion adjustment plate 25. The spacer ring 26 is generally shaped like a threaded track 23. The cylinder is cylindrical, and the outer wall of the spacer ring 26 is uniformly perforated with grooves. The surface of the switching plate 25 is uniformly perforated with vent holes 27. The side wall of the switching plate 25 is uniformly rotatably connected to the connecting pipe 28. In the initial state, the vent holes 27 and the connecting pipe 28 are staggered, and at this time, the external air source can only input airflow into the main air column 21 through the spacer ring 26. After the switching plate 25 is rotated 45 degrees clockwise, the vent holes 27 and the connecting pipe 28 are aligned. At this time, the external air source can input airflow into the main air column 21 through the spacer ring 26 and the connecting pipe 28.

[0029] Specifically, in the initial state, such as Figure 7 As shown, the ventilation holes 27 on the surface of the conversion adjustment plate 25 are completely offset from the connecting pipe 28. At this time, the airflow input from the external air source can only enter the main air column 21 through the spacer ring cylinder 26 due to structural limitations. When the airflow reaches the main air column, it will first impact the vortex component 24. The vortex component 24 is composed of inclined fan-shaped plates. Guided by it, the airflow moves in a spiral motion along the threaded track 23 on the outer wall of the central axis 22, forming a stable vortex. At this stage, as the shape of the inflatable base pad 1 gradually stabilizes, two operations can be carried out simultaneously: First, based on the support of the base pad, the folds of the tent fabric 12 can be easily adjusted to allow the tent fabric 12 to initially expand; second, based on the actual area and distribution of the inflatable base pad 1 after it is formed, tent pegs can be precisely planned and installed to lay a good foundation for tent anchoring, so as to realize the parallel operation of inflation and erection, and improve efficiency.

[0030] Once the inflatable base pad 1 reaches the preset molding state, manually drive the conversion adjustment plate 25 to rotate 45 degrees clockwise. Figure 8 As shown, at this time, the vent 27 and the connecting pipe 28 are aligned, widening the airflow path. In addition to continuing to supply air through the spacer ring 26, the external air source can also directly supply airflow to the branch structure of the air column frame 11 through the connecting pipe 28. During high-speed inflation, the vortex component 24 and the threaded track 23 work continuously: the vortex component 24 maintains the rotational characteristics of the airflow, allowing the high-speed airflow to be evenly distributed at the branch node, reducing turbulence and air resistance; the threaded track 23 uses spiral flow guidance to form a pressure gradient inside the main air column 21, automatically compensating for the air pressure loss caused by the height difference. With the cooperation of dual-path air supply, the airflow quickly fills the upper space of the tent, pushing the air column frame 11 to inflate evenly, efficiently supporting the tent fabric 12, and completing the overall shaping of the tent.

[0031] Based on Example 1, please refer to Figures 1-11 As shown, the connecting pipe 28 is located at the interval between the main air column 21 and the spacer ring 26. After the switching plate 25 is rotated forty-five degrees, the grooves on the outer wall of the spacer ring 26 correspond to the connecting pipe 28. The output end of the main air column 21 is connected to the diverting cylinder 29. The output end of the main air column 21 has a gradually narrowing funnel shape. A flow divider 210 is fixedly connected inside the diverting cylinder 29. The cross-section of the flow divider 210 is an isosceles triangle, and the tip is directly opposite the output end of the main air column 21. The two sides of the diverting cylinder 29... The branch pipes 211 are symmetrically connected and are L-shaped. Each vertical part of the branch pipe 211 is equipped with a pressure valve 214, and each bend of the branch pipe 211 is equipped with a flexible hose 212. The flexible hose 212 is made of elastic material and has a smooth interior and reinforcing ribs on the outer wall. The flexible hose 212 adapts to airflow with different impact forces through its own elastic deformation. Each bend of the flexible hose 212 is equipped with a flow guide plate 213, which is incompletely arc-shaped.

[0032] Specifically, when the airflow enters the steering cylinder 29 from the main air column 21, the funnel-shaped contraction design at the output end of the main air column 21 significantly increases the airflow velocity, forming a high-speed jet. This acceleration effect enhances the penetration of the airflow, providing sufficient kinetic energy for subsequent branch transmission. The high-speed airflow first impacts the isosceles triangular splitter plate 210 inside the steering cylinder 29, with its tip precisely facing the direction of the airflow, evenly dividing the concentrated airflow into two symmetrical branches. These branches are then smoothly guided into the branch pipes 211 on both sides of the steering cylinder 29 along the inclined surfaces on both sides of the splitter plate 210. Avoiding the airflow impact loss and vortex phenomenon common in traditional right-angle turns, the branch pipe 211 is L-shaped overall. Its vertical pressure valve 214 is closed during the initial inflation phase, ensuring that airflow preferentially fills the nearby air passage. Once the air pressure in the main air column 21 and surrounding area reaches the threshold, the pressure valve 214 automatically opens, allowing airflow to enter deeper branch structures. This stepped inflation logic avoids wrinkles or structural imbalances in the distal air column 21 caused by inflation lag. When the airflow reaches the curved section of the branch pipe 211, the bend... The flexible hose 212 begins to play a crucial role: made of elastic material, the hose undergoes adaptive deformation under the impact of airflow. During low-speed inflation, the hose expands slightly to increase the flow cross-sectional area and reduce air resistance. During high-speed inflation, the outer wall reinforcement limits excessive expansion, while the smooth inner wall reduces airflow friction loss, allowing the airflow to maintain a stable flow rate when turning. At the same time, the incompletely curved guide plate 213 inside the curved hose 212 further guides the airflow trajectory. The curved profile of the plate conforms to the natural turning path of the airflow, forcing the airflow to flow along the wall surface, reducing turbulence caused by sudden changes in direction, and ensuring that the airflow remains in an orderly laminar state during the turning process. When the conversion plate 25 is rotated 45 degrees, the groove on the outer wall of the spacer ring 26 precisely connects with the connecting pipe 28. At this time, the airflow between the main air column 21 and the spacer ring 26 is diverted to each branch through the connecting pipe 28, forming a synergy with the airflow guided by the steering cylinder 29, ensuring that the airflow in the entire air path is evenly and efficiently transmitted to every corner of the tent, ultimately achieving rapid forming of the air column frame 11 and flat support of the tent fabric 12.

[0033] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
