Since the inflation device is applied in many fields, this common problem may damage the user experience of the user. CONTENT OF THE UTILITY MODEL

[0003] The present application aims at the above-mentioned deficiencies in the prior art, and provides an easy exhaust device to solve at least one of the above-mentioned technical problems, and the specific structure is as follows:

[0004] An easy exhaust device, comprising a device main body and a flow guide assembly. The device main body is provided with at least one air nozzle, and the device main body forms a cavity; at least part of the flow guide assembly is located in at least one cavity in the device main body to form at least one exhaust passage communicated between the cavity and the air nozzle.

[0005] In some specific embodiments, the flow guide assembly comprises at least one first flow guide member;

[0006] Or the flow guide assembly comprises at least one first flow guide member and at least one second flow guide member;

[0007] The second flow guide member extends to the area outside the first flow guide member in the device main body; at least one end of the second flow guide member is connected with the first flow guide member, or one end of the second flow guide member is connected with the first flow guide member, and the other end is connected with the inner side wall of the device main body.

[0008] It should be noted that the present application does not specifically limit the number and positional relationship of the first flow guide member and the second flow guide member, and the user can arrange the position of the first flow guide member and the second flow guide member according to the actual needs, for example, there can be multiple first flow guide members, which can be arranged in parallel or staggered with each other, and the lengths of the multiple first flow guide members can be different.

[0009] In some specific embodiments, at least one end of the first flow guide member is arranged on the inner side wall of the device main body.

[0010] In some embodiments, the inner side wall of the device body is provided with a connecting member for connecting the flow guide assembly. Specifically, the connecting member can be connected to the flow guide assembly by means of adhesion, crimping or clamping, etc. In one embodiment, the connecting member comprises a connecting ring, and the flow guide assembly is connected to the inner side wall of the device body by buckling with the connecting ring.

[0011] In some embodiments, the shape of the flow guide assembly matches the shape of the inner cavity of the device body. In one embodiment, the flow guide assembly comprises a strip structure, and / or a bifurcated structure, and / or a cross structure.

[0012] The shape of the device body can comprise one or more of a divergent shape, an axisymmetric shape, a polygonal shape, and an irregular shape. For example, the shape of the device body can be a cross shape, an I shape, and a rice shape, etc., and the flow guide assembly is arranged in accordance with the shape of the device body. In actual application, when the shape of the device body is a cross shape, the flow guide assembly can be formed by two first flow guide members arranged in a staggered manner. When the shape of the device body is an I shape, the flow guide assembly can be formed by two first flow guide members and a second flow guide member which is connected to the two first flow guide members, so that the flow guide assembly penetrates through the inside of the device body, thereby maximizing the exhaust of the device body.

[0013] In some embodiments, the roughness of the outer part of the flow guide assembly is different from the roughness of the inner side wall of the device body. By setting the roughness of the two different, the outer part of the flow guide assembly and the inner side wall of the device body are not completely fitted, but can form gaps that allow air to pass through, which further form exhaust passages.

[0014] In some embodiments, the flow guide assembly comprises an elastic member, which comprises a spring rope, and / or a spring, and / or a hose, and / or a flexible support, and / or a telescopic tube.

[0015] In actual application, the spring rope has both softness and stretchability, and gaps are formed between the effective turns of the spring rope, so that air can flow through the gaps to further form exhaust passages along the spring rope. The user can adjust the length and / or position of the exhaust passage in the device body by stretching the spring, thereby helping to exhaust the device body. In one embodiment, when a closed air space is formed inside the device body during the exhaust process, the flow guide assembly is brought into contact with the closed air space inside the device body, which can break the closure of the air space and guide the air in the air space outwards, thereby achieving effective exhaust of the device body.

[0016] In some embodiments, the flow guide assembly comprises a flow guide tube, and the flow guide tube is provided with a flow guide opening on the tube body, which is used to form an exhaust passage in the flow guide tube and near the tube body.

[0017] In some embodiments, the device body comprises a flexible airbag and / or a flexible hose.

[0018] In some embodiments, the air nozzle is arranged on the device body close to the flow guide assembly. By arranging the air nozzle close to the flow guide assembly, the exhaust passage formed in the device body can have a larger contact range with the air nozzle, and the exhaust passage can be more unobstructed through the air nozzle.

[0019] It should be noted that the diameter of the air nozzle and the diameter of the flow guide assembly are not specifically limited in the present application. In one embodiment, the diameter of the air nozzle can be greater than or equal to the diameter of the flow guide assembly, so that the user can put the flow guide assembly into the device body through the air nozzle for installation. At the same time, the user can also put different sizes or different materials of the flow guide assembly into the device body according to the specific needs of the exhaust. In one embodiment, the diameter of the air nozzle can also be smaller than the diameter of the flow guide assembly, and the flow guide assembly can be placed in the device body before the device body is closed to achieve the installation of the flow guide assembly.

[0020] In some embodiments, a sealing member is further included, and the device body comprises at least two end portions; the sealing member is arranged on the end portion to close the end portion of the device body to form a cavity in the device body. In actual application, the flow guide assembly can be arranged at the position of the line connecting between the at least two end portions inside the device body, and at least one end of the flow guide assembly is fixedly connected with one of the sealing members.

[0021] In some embodiments, the device body comprises a TPU film, and / or a TPU coated fabric, and / or a PET film, and / or a PVC film, and / or a PVC coated fabric, and / or a rubber film, and / or a nylon structure.

[0022] In some embodiments, a protective sleeve is further included, which is sleeved outside the device body. When the device body adopts a film material with a relatively thin thickness, it can be scratched and rubbed by the outside. Therefore, the device body can be protected by sleeving the protective sleeve.

[0042] Embodiments

[0043] The present application provides an easy exhaust device, which can realize rapid and efficient exhaust, and the specific scheme is as follows:

[0044] An easy exhaust device, comprising a device main body 1 and a flow guide assembly 2. At least one air nozzle 11 is arranged on the device main body 1, and a cavity 12 is formed in the device main body 1; at least part of the flow guide assembly 2 is located in at least one cavity 12 in the device main body 1 to form at least one exhaust passage 3 communicated by the cavity 12 and the air nozzle 11, as shown in Figure 1 and Figure 2 .

[0045] In some specific embodiments, the flow guide assembly 2 comprises at least one first flow guide piece 21;

[0046] Or the flow guide assembly 2 comprises at least one first flow guide piece 21 and at least one second flow guide piece 22;

[0047] The second flow guide 22 extends in the device body 1 to an area outside the first flow guide 21; at least one end of the second flow guide 22 is connected with the first flow guide 21, or one end of the second flow guide 22 is connected with the first flow guide 21 and the other end is connected with the inner side wall of the device body 1.

[0048] It should be noted that the number and positional relationship of the first flow guide 21 and the second flow guide 22 are not specifically limited in the present application. The user can arrange the positions of the first flow guide 21 and the second flow guide 22 according to actual needs, for example, there can be multiple first flow guides 21, such as Figure 6 As shown, the multiple first flow guides 21 can be arranged in parallel or staggered with each other, and the lengths of the multiple first flow guides 21 can also be different from each other.

[0049] In some specific embodiments, at least one end of the first flow guide 21 is arranged on the inner side wall of the device body 1.

[0050] In some specific embodiments, the inner side wall of the device body 1 is provided with a connecting piece for connecting the flow guide assembly 2, such as Figure 8 As shown, the connecting piece can be connected with the flow guide assembly 2 by means of pasting, crimping or clamping, etc. In one specific embodiment, the connecting piece includes a connecting ring, and the flow guide assembly 2 is connected with the inner side wall of the device body 1 by buckling.

[0051] In some specific embodiments, the shape of the flow guide assembly 2 matches the shape of the inner cavity 12 of the device body 1.

[0052] In one specific embodiment, the shape of the device body 1 can include one or more of divergent shape, axisymmetric shape, polygon, irregular shape; for example, the shape of the device body 1 can be cross-shaped, H-shaped and rice-shaped, etc., and the flow guide assembly 2 includes a strip structure, and / or a bifurcated structure, and / or a cross structure. When there are multiple flow guide assemblies 2, the flow guide assemblies 2 can be overlapped with each other or clamped with each other by their own structures.

[0053] In actual application, the flow guide assembly 2 matches the shape of the inner cavity 12 of the device body 1 and penetrates the inside of the device body 1, such as Figure 3 As shown, when the device body 1 is cross-shaped, the flow guide assembly 2 can be formed by two first flow guides 21 arranged in a staggered manner; as Figure 4 As shown, when the device body 1 is H-shaped, the flow guide assembly 2 can be formed by two first flow guides 21 and a second flow guide 22 respectively connected with the two first flow guides 21, so that the flow guide assembly 2 can maximize the exhaust in the device body 1.

[0054] In some embodiments, the roughness of the outer surface of the flow guide assembly 2 and the roughness of the inner wall of the device body 1 are different. By setting the roughness of the outer surface of the flow guide assembly 2 and the roughness of the inner wall of the device body 1 to be different, the outer surface of the flow guide assembly 2 and the inner wall of the device body 1 do not completely fit together, but can form gaps that allow air to pass through. These gaps can prevent the side wall of the cavity 12 in the device body 1 from being tightly fitted during the exhaust process, and form an exhaust passage 3 that communicates with the air outlet 11 in the cavity 12 of the device body 1.

[0055] In some embodiments, the flow guide assembly 2 includes an elastic member, which includes a spring cord, and / or a spring, and / or a hose, and / or a flexible support, and / or a telescopic tube.

[0056] In actual applications, the spring cord has the characteristics of softness and stretchability, and gaps are formed between effective turns in the spring cord, allowing air to flow through the gaps and further form an exhaust passage 3 along the spring cord. The user can adjust the length and / or position of the exhaust passage 3 in the device body 1 by stretching the spring, which helps the device body 1 to exhaust. In one embodiment, when a closed air space is formed inside the device body 1 during the exhaust process, the closed air space is broken by contacting the flow guide assembly 2 with the closed air space inside the device body 1, which can guide the air in the air space outwards, achieving effective exhaust of the device body 1.

[0057] Specifically, the two ends of the spring cord are arranged at different positions in the device body 1. In one embodiment, one or more fixing points are provided in the device body 1 to fix the spring cord. By using a spring cord, such as Figure 4 and Figure 5 When the positions of the plurality of spring cords are staggered, the spring cords can be fixed to each other by the gaps between the effective turns. In one embodiment, as long as the device body 1 can be effectively exhausted, the spring cords can also be directly overlapped without being fixed relative to each other according to actual requirements.

[0058] In some embodiments, the flow guide assembly 2 includes a flow guide tube 23, and the flow guide tube 23 has a flow guide opening on the tube body for forming an exhaust passage 3 in the flow guide tube 23 and near the tube body of the flow guide tube 23. As shown in Figure 7 In one specific application, the flow guide tube 23 is a hose, and the air in the device body 1 can flow along the flow guide tube 23 through the flow guide opening on the tube body. The user can set the number and arrangement of the flow guide openings on the tube body of the flow guide tube 23 according to actual conditions.

[0059] In some embodiments, the shape of the flow guide assembly 2 matches the shape of the cavity 12 in the device body 1.

[0060] In some embodiments, the device body 1 comprises a flexible airbag and / or a flexible hose.

[0061] In some embodiments, the air nozzle 11 is arranged on the device body 1 close to the flow guide assembly 2, specifically, the air nozzle 11 is arranged within the range of the exhaust channel 3, the shorter the distance between the air nozzle 11 and the flow guide assembly 2, the larger the contact area between the air nozzle 11 and the exhaust channel 3, and the better the exhaust effect of the gas in the exhaust channel 3. In actual application, the air nozzle 11 is a hard structure with higher rigidity than the material of the device body 1, which can open a relatively stable opening on the device body 1 when the air nozzle 11 is opened, so that the air nozzle 11 can not be affected by the deformation of the device body 1 during the exhaust process.

[0062] It should be noted that the diameter of the air nozzle 11 and the diameter of the flow guide assembly 2 are not specifically limited in the present application. In one embodiment, the diameter of the air nozzle 11 can be greater than or equal to the diameter of the flow guide assembly 2, so that the flow guide assembly 2 can enter the device body 1 through the air nozzle 11. By setting the diameter of the air nozzle 11 to be greater than the diameter of the flow guide assembly 2, the user can put the flow guide assembly 2 into the device body 1 for installation through the air nozzle 11, and at the same time, the user can also put flow guide assemblies 2 of different sizes or different materials into the device body 1 for gas flow guide according to the specific needs of the exhaust; in one embodiment, the diameter of the air nozzle 11 can also be smaller than the diameter of the flow guide assembly 2, and the flow guide assembly 2 can be placed in the device body 1 before the device body 1 is closed. In actual application, the user can use flow guide assemblies 2 of different diameters according to actual use needs.

[0063] It should be noted that in the present embodiment, the number of air nozzles 11 on the device body 1, the specific installation position of the air nozzle 11, the number of flow guide assemblies 2 in the device body 1, the specific arrangement position of the flow guide assembly 2, and the number and position of the exhaust channel 3 are not limited, as long as the technical effect of efficiently exhausting the device body 1 can be achieved. The user can also set multiple air nozzles 11 on the device body 1 according to the situation in actual application, and set flow guide assemblies 2 suitable for the shape of the device body 1 at different positions of the device body 1 to form multiple exhaust channels 3 corresponding to different air nozzles 11. Thus, multiple exhaust channels 3 can simultaneously exhaust different areas of the device body 1 through different air nozzles 11 during the exhaust process, which is very suitable for the exhaust of large device bodies 1.

[0064] In some specific embodiments, a sealing member 14 is also included. The device body 1 includes at least two ends 13. The sealing member 14 is disposed on the ends 13 and is used to close the ends 13 of the device body 1 to form a cavity 12 inside the device body 1. In practical applications, the flow guiding component 2 can be disposed at the position connecting the at least two ends 13 inside the device body 1. At least one end of the flow guiding component 2 is fixedly connected to one of the sealing members 14. Alternatively, the connecting member 15 can be fixedly connected to the sealing member 14, so that the flow guiding component 2 is connected to the end where the sealing member 14 is located through the connecting member 15.

[0065] In a specific application, the main body 1 of the device is a flexible hose used for supporting structures such as tents. The flexible hose can have various lengths and can be connected to other hoses. In one specific embodiment, the flexible hose is strip-shaped, such as... Figure 1 As shown, the two ends of the flexible hose are its ends 13, and each end 13 is equipped with a sealing member 14. The two ends of the flow guiding component 2 are fixedly connected to the sealing members 14 at both ends of the flexible hose, allowing passage through the interior of the flexible hose. The air nozzle 11 is positioned on the main body 1 corresponding to the flow guiding component 2. During use, the user inflates the flexible hose through the air nozzle 11, shaping it and providing support before use. After use, when the flexible hose needs to be vented and folded for storage, the gas inside the flexible hose can be discharged through the venting channel 3 formed by the flow guiding component 2 from the air nozzle 11. During the venting process, the user can also manually adjust the position of the flow guiding component 2 within the flexible hose at any time, allowing the flow guiding component 2 to contact different areas within the flexible hose to break the enclosed air space within the main body 1.

[0066] In some specific embodiments, the device body 1 includes a TPU membrane, and / or a TPU-coated fabric, and / or a PET membrane, and / or a PVC membrane, and / or a PVC-coated fabric, and / or a rubber membrane, and / or a nylon structure.

[0067] In some specific embodiments, a protective sleeve is also included on the outside of the device body 1. When the device body 1 is made of a thin film material, it may be subject to external friction and scratches. Therefore, the outer surface of the device body 1 can be protected by using a protective sleeve.

[0068] The embodiment provides an easy exhaust device, which comprises a device main body and a flow guide component, at least part of the flow guide component is arranged in at least one cavity in the device main body, so as to form at least one exhaust passage communicated by the cavity and the air nozzle, thereby realizing efficient exhaust of the cavity in the device main body, effectively preventing the problem that a closed air space appears in the device main body during the exhaust process, causing the exhaust to be not smooth, and the device has low manufacturing cost, simple structure, convenient operation and the like, and can effectively improve the use experience of users.

[0069] The above is a specific description of the preferred embodiment of the application, but the application creation is not limited to the embodiment, and those skilled in the art can make various equivalent modifications or replacements without departing from the spirit of the application.
