Description

Technical Field

[0001] This utility model relates to a travel bag structure, and more particularly to an inflatable, vacuum-sealed waterproof travel bag. Background Technology

[0002] Nowadays, people's living standards are gradually improving, and they have sufficient time, energy, and financial resources to travel. However, during travel, they often encounter situations like crossing rivers and streams, and rain or snow, which can easily get their bags wet, causing inconvenience. Furthermore, people often choose to bring different quantities of items depending on the distance and route of their trip. Current travel bags typically have a fixed capacity and volume, and when the items carried are insufficient, larger bags take up considerable space. In such cases, people often choose different sized travel bags to meet their needs. However, choosing different sized travel bags means travelers constantly carry different sizes, which increases travel costs. Therefore, there is an urgent need to design a travel bag that can change size and is waterproof, solving the problem that travel bags cannot adjust their size according to the amount of contents. However, current travel bags cannot solve both of these problems simultaneously. Summary of the Invention

[0003] This utility model provides a waterproof travel bag with a simple structure, which can be easily adjusted according to the number of items carried, can be quickly inflated and deflated to ensure the integrity of the items inside the bag, and is easy to adjust the size of the bag. It solves the technical problems of existing travel bags, such as complex structure, single function, multiple layers, and inconvenience in inflating, deflated and adjusting the size of the bag.

[0004] The above-mentioned technical problem of this utility model is solved by the following technical solution: an inflatable and deflated waterproof travel bag, comprising a travel bag body made of a soft waterproof material, an opening on the bag body with a waterproof and airtight zipper installed at the opening, and an air pump connection port on the bag body. An inflation / deflation valve body is installed on the air pump connection port, and the inflation / deflation valve body includes an inflation base with a rotatable inflation / deflation port. The volume of the bag can be changed by inflation / deflation. When the bag contains few items, the volume can be reduced by deflation; when the bag contains many items, the volume can be increased by inflation. This meets the needs of different travels. Simultaneously, after deflation, the relative positions of the items inside the bag remain relatively fixed, preventing excessive displacement and friction that could damage the items, thus ensuring the integrity of the contents. Inflation, on the other hand, provides cushioning for fragile items, further ensuring their integrity. The inflatable bag can also be used as a stool or life-saving equipment, enhancing its functionality and allowing for use in various situations. It also features a waterproof and airtight zipper to ensure waterproofing and airtightness within the bag. The inflation / deflation valve on the bag allows for easy inflation or deflation as needed, with a simple structure and convenient operation, eliminating the need to replace different valves.

[0005] Preferably, the base is fixed to the package body, and a snap-on cap is installed on the base. The snap-on cap connects to the inflation / deflation port after inflation / deflation is completed. The snap-on cap achieves sealing during inflation / deflation.

[0006] Preferably, the inflation / deflation port includes a base, which is connected to a pedestal via a rotating rod. An inflation end and a deflation end are located on both sides of the base. The base can be rotated as needed to select either the inflation or deflation end for inflation or deflation. The base can rotate around the rotating rod, and the inflation / deflation port can also be isolated via the rotating rod for easy rotation and changing of the end face to select the desired port.

[0007] Preferably, the base has a mesh-like through-hole at its center, and the inflation end and deflation end are two hollow cylinders. A sealing gasket is located at the bottom of the deflation end, positioned at the mesh-like through-hole in the center of the base. The mesh-like through-hole facilitates inflation and deflation. During inflation, the sealing gasket is located below the mesh-like through-hole and can be blown open towards the bag body, thus opening the mesh-like through-hole. During deflation, the sealing gasket is located above the mesh-like through-hole and is drawn open by the air pump, exposing the mesh-like through-hole. The sealing gasket is always aligned with the airflow direction and will not obstruct the airflow. After inflation and deflation, the gasket is pressed against the mesh-like through-hole by the pressure difference between the inside and outside of the bag, achieving a seal.

[0008] Preferably, the sealing gasket has a positioning post formed on it, and a positioning hole is provided in the center of the mesh through-hole in the center of the base, with the positioning post inserted into the positioning hole. This ensures that the sealing gasket will not fall off.

[0009] Preferably, the base has a through hole at its center, which is clearance-fitted with the cylinder of the inflation or deflation end. Connecting the inflation / deflation port to the base allows for convenient inflation / deflation.

[0010] Preferably, one side of the base is connected to a cover via a connecting strap, and the other side of the base is connected to an inflation / deflation port via a rotating rod. The cover and inflation / deflation port are located on opposite sides of the base, facilitating rotation and adjustment of the port, and also making it easy to fasten the cover. After selecting the correct direction for the inflation / deflation port, connect it to the base. After inflation / deflation is complete, close the cover to achieve a seal.

[0011] Preferably, the air pump connection port is located on the lower side of the package.

[0012] Preferably, adjustment strap mounting buckles are also provided on the front and rear end faces of the lower side of the bag body. This facilitates adjustment of the bag body's volume.

[0013] Therefore, the inflatable and deflatable waterproof travel bag of this invention has the following advantages: the bag body is made of a soft waterproof material, which can effectively achieve waterproofing, and the soft body allows the bag to change volume according to usage, making it multi-functional. Inflation and deflating can be achieved simultaneously through the inflation / deflating port, adjusting the bag's volume. The overall structure is simple and easy to operate.

[0018] The technical solution of the utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0019] Example 1:

[0020] like Figure 1 and 2As shown in Figure 3, an inflatable and deflatable waterproof travel bag includes a bag body 1 made of PVC mesh fabric. An opening is provided on the rectangular bag body, and a waterproof and airtight zipper 2 is installed at the opening. Handles 3 are installed on both sides of the bag body, and adjustment strap mounting buckles 4 are installed on both sides of the bottom of the bag body 1. Adjustment straps are installed on the buckles 4, located at the bottom of the bag body, allowing the bag body 1 to be folded down. An air pump connection port is provided at the bottom of the bag body 1, and an inflation / deflator valve body 5 is installed on the air pump connection port. The inflation / deflator valve body 5 includes an inflation base 6, which is circular, with a through hole 7 in the center. A cover 9 is connected to one side of the base 6 via a connecting strap 8, and an inflation / deflator port is connected to the other side of the base 6 via a rotating rod. The inflation / deflation port includes a disc-shaped base 14 with a mesh through-hole 11 at its center. Two hollow cylinders are formed at both ends of the base 14; one cylinder is the inflation end 13, and the other is the deflation end 15. A rubber sealing gasket 16 is installed on the deflation end 15, positioned above the mesh through-hole 11. The cylinder of the deflation end 15 provides a space for the rubber sealing gasket 16 to move. A positioning post 12 is formed at the center of the rubber sealing gasket 16, and a positioning hole is provided at the center of the mesh through-hole, into which the positioning post 12 is inserted. The cylinders of the deflation end 13 and the inflation end 15 have the same shape and are clearance-fitted with the through-hole 7 at the center of the base.

[0021] When using, shrink the travel bag as needed, insert the pump into the suction end, and begin suction. After shrinking, tighten the adjustment strap to further reduce the bag's size. The rubber sealing gasket is pressed against the mesh openings due to the pressure difference between the inside and outside of the bag, and then the cap is used for further sealing. If a larger volume is required, rotate the inflation / extension port to connect the inflation end to the air pump and inflate to increase the volume.

[0022] Example 2:

[0023] like Figure 4 As shown, unlike Example 1, the travel bag can be made into a longer bag body suitable for carrying skis or golf clubs, depending on the intended use.
