Description

Technical Field

[0001] This utility model relates to the technical field of inflation devices, specifically to an inflation device with a replaceable built-in air pump, which is particularly suitable for products that need to be inflated or deflated, such as air mattresses and air toys. Background Technology

[0002] Existing inflation devices with built-in air pumps typically employ a fixed design, where the air pump is permanently fixed to the inflation tube or inner liner via adhesive or welding. This design presents the following problems:

[0003] Replacement is difficult: When the air pump is damaged or needs maintenance, the glued or welded parts must be removed in a destructive manner, which is complicated and can easily damage the air tube or inner liner.

[0004] High maintenance costs: Replacing an air pump often requires specialized tools or returning it to the factory, increasing the user's time and financial costs. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing an inflation device with a replaceable built-in air pump. Through optimized window design and fixing method, convenient replacement of the air pump and reliable sealing are achieved.

[0006] This utility model is achieved through the following technical solution:

[0007] A replaceable inflation device with a built-in air pump includes an air pump, an inflation tube, and an inner liner. The inner liner is located inside the inflation tube, and the air pump is located inside the inner liner. Both the inner liner and the inflation tube are provided with windows. The air inlet of the air pump passes through the windows of the inner liner and the inflation tube, and is connected to the outside.

[0008] The bonding range of the inner liner and the inflation tube includes at least: a closed bonding formed by bonding the edge of the inner liner opening and the edge of the inflation tube opening, as well as an extended bonding.

[0009] Furthermore, the extended bonding is a linear bonding of the inner liner and the inflation tube, and the linear bonding and the closed bonding are connected.

[0010] Furthermore, the inner liner is also equipped with an air nozzle, and the air outlet of the air pump is connected to the air inlet of the air pipe through the air nozzle.

[0011] Furthermore, it has a cut; the cut is located within the bonding area and extends to the opening.

[0012] Furthermore, it also includes a zipper; the two strips of the zipper are respectively located on the two sides formed by the cut.

[0013] Furthermore, it also includes Velcro; the hook and loop sides of the Velcro are respectively located on the two sides formed by the cut.

[0014] Furthermore, it also includes a clamp; the adhesive area of ​​the clamp on the inflation tube.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] The air pump is easy to replace: the design of cutting open the adhesive side greatly simplifies the replacement process, and users can complete the operation without professional tools, which greatly reduces the difficulty of maintenance.

[0017] Balancing sealing and strength: The fastening methods of Velcro, zippers, or clamps ensure that the air pump is not unstable due to outward turning, while also making it easy to replace the air pump.

[0018] Low cost and high reliability: No complex split structure is required. Existing bonding technology is used in combination with simple fasteners, which improves durability while reducing costs.

[0019] Wide range of applications: It is especially suitable for scenarios that require frequent maintenance, such as air mattresses and outdoor inflatable equipment, and is also compatible with the replacement needs of air pumps with different power. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0027] Example 1:

[0028] Reference Figure 1This embodiment includes an air pump, an inner liner, and an air tube; wherein the inner liner and the air tube are made of PVC coated polyester interwoven fabric or TPU material; wherein the inner liner is located inside the air tube, and the air pump is located inside the inner liner.

[0029] Both the inner liner and the inflation tube have windows, namely window A and window B, which face each other. The inflation pump has an air inlet and an air outlet. The air inlet of the inflation pump is connected to the outside through windows A and B. The air outlet of the inflation pump is detachably connected to the inflation nozzle installed on the inner liner.

[0030] The edges of window A and window B are bonded together, forming a sealed chamber between the area outside the inner liner and the area inside the inflation tube, thus creating a closed bond. Then, the inflation pump located inside the inner liner inflates the sealed chamber through the air nozzle.

[0031] The bonding area between the edges of window A and window B has expanded. When replacing the air pump, cut along the incision line within the bonding area. The sealed chamber will remain sealed without being damaged. Open the incision, disconnect the air nozzle from the air pump, and replace the air pump. Then reseal the incision with tape to restore its usability.

[0032] In this embodiment, the bonding range is expanded in the form of a strip bonding range, the extension direction of which is parallel to the central axis of the inflation tube, as detailed in the following reference. Figure 2 The cut extends from the inner edge of the window to the strip bonding area.

[0033] Example 2,

[0034] The difference between this embodiment and Embodiment 1 is that the bonding range in this embodiment is expanded to a ring-shaped bonding range; the ring-shaped bonding range expands outward from the closed bonding at the edge of the window opening, as detailed in the following reference. Figure 3 The cut extends from the inner edge of the window to the annular bonding area.

[0035] The annular bonding range can be compared to other similar bonding methods, such as fan-shaped and linear bonding. This patent provides an annular bonding range, a strip bonding range, and a linear bonding range (see reference). Figure 4 Both are extensions of closed bonding, which aim to illustrate that after the cut is separated, the area outside the inner liner and inside the air tube is still a closed chamber.

[0036] Example 3,

[0037] Reference Figure 5 After inflation, the two sides of the cut may turn outwards. In order to ensure the stability of the air pump inside, this embodiment uses a zipper to connect the two sides of the cut.

[0038] The difference between this embodiment and Embodiment 1 is that the two strips of the zipper are sewn onto the two sides of the cut (without affecting the sealing effect of the enclosed chamber). The zipper is opened by sliding from the extended adhesive area towards the opening.

[0039] Example 4,

[0040] The difference between this embodiment and embodiment 3 is that the zipper is replaced with Velcro, and the hook and loop sides of the Velcro are respectively set on the two sides of the cut.

[0041] Example 5,

[0042] The difference between this embodiment and embodiment 3 is that the zipper is replaced with a clamp, which is fitted onto the inflation tube and covers the bonding area.

[0043] In summary, the main purpose of this design is to solve the problem of the difficulty in replacing the built-in air pump. The design involves cutting along the adhesive area from the window side to enlarge the window area, and then removing the air pump. After installing the air pump, the air outlet and the air nozzle are directly opposite each other. After inserting the inner liner, Velcro or zippers are installed on both sides of the adhesive joint, or clamps are installed on the inflation tube to secure the cut portion and prevent outward flipping after inflation.

[0044] It should be noted that the above description is merely a preferred application example of this utility model and is not intended to limit the scope of protection of this utility model. All technical solutions employing equivalent substitutions or equivalent transformations are within the scope of protection of this utility model.
