Abstract
Description
Technical Field
[0001] This utility model relates to outdoor equipment, and more particularly to an improvement of a spherical inflatable tent. Background Technology
[0002] Inflatable tents are a common type of outdoor camping equipment. Typical tents are either arched or pyramidal in shape, usually secured to the ground with cables. They are generally pyramidal in shape. Another type is the inflatable spherical tent, which, when inflated, forms a spherical shape and is often made of transparent material. This type of tent has no frame and relies on air pressure for support, resulting in poor overall pressure resistance. For example, a conventional inflatable tent includes an inflatable base and an inflatable column. The inflatable column is fixedly installed on top of the base, and the base and column are integrated and internally connected. An inflation / de-inflation device is installed on the base or column. This invention eliminates the need to carry and use an inflatable mat. The base and column are integrated, and the tent can be inflated in one go using the inflation / de-inflation device. However, the tent is too large, resulting in a long inflation time and low inflation efficiency. Furthermore, if the inflatable tent breaks, all the air will leak out, affecting its usability. Utility Model Content
[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a spherical inflatable tent.
[0004] This utility model is achieved using the following technical solution: a spherical inflatable tent, comprising a spherical body and a supporting rib, wherein a sandwich layer is provided inside the body and the supporting rib, and a plurality of airbags are provided inside the sandwich layer, wherein the plurality of airbags are connected end to end and arranged along the length direction of the supporting rib, adjacent airbags are interconnected, and an inflation nozzle is provided on the body, wherein the inflation nozzle is connected to one of the airbags, and a sealing cap is provided on the inflation nozzle.
[0005] A one-way air intake valve and a differential pressure valve are provided between adjacent airbags. The differential pressure valve is located on one side of the one-way air intake valve and inside the airbag. The valve plate of the differential pressure valve rotates in the same direction as the airflow inside the airbag.
[0006] The differential pressure valve includes a valve body and a valve plate. The valve body is fixed between adjacent air bladders. The valve body is provided with an air inlet and an air outlet. The valve body is provided with a cavity for mounting the valve plate. The air inlet and the air outlet are respectively connected to the cavity. The valve plate is rotatably connected to the inner wall of the cavity. A torsion spring is provided between the valve plate and the inner wall of the cavity. The torsion spring drives the valve plate to abut against the bottom of the cavity.
[0007] The main body includes an arched inlet and a spherical tent body. The support rib is provided on the spherical tent body and extends outward from the top of the spherical tent body. The arched inlet is connected to the spherical tent body, and the support rib is provided at the end of the arched inlet away from the spherical tent body.
[0008] The main body includes an inner adhesive film and an outer adhesive film, and the support rib is disposed between the outer adhesive film and the inner adhesive film, and the outer wall of the support rib is fixed on the outer adhesive film and the inner adhesive film.
[0009] The inner layer of the adhesive film and the outer layer of the adhesive film are respectively provided with a set of support ribs on the opposite side.
[0010] Compared to existing technologies, this invention utilizes a differential pressure valve whose valve plate rotates in the same direction as the airflow within the airbag. During use, each airbag operates relatively independently; during inflation, the airbags inflate sequentially, causing the support ribs to harden due to air pressure. This, in turn, supports the main body, making inflation easier. Even if localized leakage occurs, it only affects one or a few airbags, and the overall inflation remains unaffected.

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0015] Reference Figure 1-2A spherical inflatable tent includes a spherical main body 1 and supporting ribs 2. A sandwich structure is provided within the main body 1 and the supporting ribs 2, containing several airbags 21. The airbags 21 are connected end-to-end and arranged along the length of the supporting ribs 2, with adjacent airbags 21 interconnected. An inflation nozzle is provided on the main body 1, communicating with one of the airbags 21, and the nozzle is capped. A one-way air inlet valve 22 and a differential pressure valve 23 are provided between adjacent airbags 21. The differential pressure valve 23 is located to one side of the one-way air inlet valve 22 and is situated within the airbag 21. The valve plate 232 of the differential pressure valve rotates in the same direction as the airflow within the airbag 21. During use, each airbag 21 operates relatively independently. During inflation, the airbags 21 inflate sequentially, causing the supporting ribs 2 to harden due to air pressure, thus supporting the main body 1 and facilitating inflation. Even if localized leakage occurs, it only affects one or a few airbags 21, and the overall inflation remains unaffected.
[0016] The differential pressure valve includes a valve body 231 and a valve plate 232. The valve body 231 is fixed between adjacent air bladders 21. The valve body 231 has an air inlet and an air outlet. The valve body 231 has a cavity for mounting the valve plate 232. The air inlet and the air outlet are respectively connected to the cavity. The valve plate 232 is rotatably connected to the inner wall of the cavity. A torsion spring is provided between the valve plate 232 and the inner wall of the cavity. The torsion spring drives the valve plate 232 to abut against the bottom of the cavity. Even if there is a partial air leak, since the differential pressure valve can only rotate in one direction, it will use the gas in the adjacent air bladders 21 to balance the pressure. Thus, the entire tent can still be used by relying solely on the balance of air pressure, and there will be no situation where it cannot be used due to air leakage.
[0017] The main body 1 includes an arched inlet and a spherical tent. Support ribs 2 are located on the spherical tent and extend outward from the top of the spherical tent. The arched inlet is connected to the spherical tent, and the support rib 2 is located at the end of the arched inlet away from the spherical tent. Similarly, when the support rib 2 is inflated, it also provides support for the arched inlet, making it stronger and less prone to collapse.
[0018] The main body 1 includes an inner adhesive film 12 and an outer adhesive film 11. A support rib 2 is disposed between the outer adhesive film 11 and the inner adhesive film 12, and the outer wall of the support rib 2 is fixed to the outer adhesive film 11 and the inner adhesive film 12. A set of support ribs 2 is provided on the side of the inner adhesive film 12 opposite to the outer adhesive film 11.
[0019] Compared to existing technologies, this invention utilizes the fact that the valve plate 232 of the differential pressure valve rotates in the same direction as the airflow within the airbag 21. During use, each airbag 21 operates relatively independently. During inflation, the airbags 21 inflate sequentially, causing the support ribs 2 to harden due to air pressure. This, in turn, supports the main body 1, making inflation easier. Even if localized leakage occurs, it only affects one or a few airbags 21, and the overall inflation remains unaffected.
[0020] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
