Description

Technical Field

[0001] The invention belongs to the electrical field, and in particular relates to a circuit structure for an inflatable device. Background Art

[0002] With the progress of society, various decorative methods emerge in our daily life, and the use of inflatable devices (such as balloons, etc.) in advertisements has become commonplace. In order to increase the visual effect of inflatable devices, many manufacturers combine colored lights or electrical devices with inflatable devices. However, the port of the inflatable device must be isolated from the internal and external gases. If the positive and negative wires of the electrical device enter the inflatable device from the end, the air tightness of the inflatable device will be greatly reduced. Therefore, the current method of combining inflatable devices with electrical devices is to install the electrical device into the inflatable device, and it is impossible to control the electrical device outside the inflatable device. Summary of the invention

[0003] Purpose of the invention: The purpose of the present invention is to address the deficiencies in the prior art and provide a circuit structure for an inflator that can achieve gas-electric separation without hindering the air tightness of the inflator.

One of the most critical features of this design is that two wires are connected to the front and back surfaces of the metal sheet by welding, so as not to break the structure of the metal sheet and ensure the sealing of the gas inside the device.

[0005] Another circuit structure for an inflatable device comprises a three-dimensional structure with a cavity, a blowing hole opened on the surface of the three-dimensional structure and a through hole No. 1 opened on the surface of the three-dimensional structure, a column surrounding the circumference of the through hole No. 1 is provided on the surface of the three-dimensional structure at a position corresponding to the through hole No. 1, a through hole No. 2 is provided on the top of the column, a cap fixed to the top of the column by screwing or snapping is provided above the column, the cap is provided with a through hole No. 3, a metal sheet covering the through hole No. 2 is clamped between the top of the column and the cap, and a conductive wire is welded to the top and bottom surfaces of the metal sheet; at least one through hole No. 1 exists on the surface provided with the through hole No. 1, and at least two through holes No. 1 are provided on all surfaces of the three-dimensional structure.

[0006] The three-dimensional structure is a cylinder, a sphere, a cuboid, a cube, an ellipsoid, a hexahedron or an octahedron having an open surface.

[0007] The outer side of the column is provided with an external thread, and the inner wall of the cap is provided with an internal thread corresponding to the outer thread of the column, and the cap is screwed with the column to fix the metal sheet sandwiched between the two. The outer side of the column or the cap can also be provided with an external thread to combine with other structures through the thread.

[0008] Among them, an airtight ring is provided between the metal sheet and the second through hole, or an airtight ring is provided between the metal sheet and the lower edge of the cap, or an airtight ring is provided between the metal sheet and the second through hole, and between the metal sheet and the lower edge of the cap, so as to further achieve the airtight function; the airtight ring can be made of organic material gasket, preferably rubber or soft plastic.

[0009] Among them, the substrate or three-dimensional structure is provided with a blowing pipe surrounding the outer periphery of the blowing hole; further, a valve nozzle is provided at the bottom end of the blowing pipe, and a circle of threads is provided at the bottom of the blowing pipe, and an end cover with corresponding threads is screwed together with the bottom of the blowing pipe, so that the bottom of the blowing pipe and the end cover lock the valve nozzle.

[0010] A most preferred structure is that the substrate is circular, and an extension surface is provided on the non-cylindrical side of the substrate to form a cylindrical structure with a missing bottom surface. The inner wall of the extension surface is provided with an internal thread, and an end cap with an external thread is screwed into the extension surface. The bottom of the end cap is provided with a positioning hole for accommodating the passage of an air blowing pipe.

[0011] A sealing ring is provided between the circumference of the top end of the end cover and the bottom of the base plate, and threads may also be provided on the outside of the end cover to combine with other structures through the threads.

[0012] Among them, positioning blocks divided into three parts are arranged on the bottom of the end cover and the circumference of the positioning hole, and the positioning blocks clamp the air blowing pipe passing through the positioning hole.

[0013] Wherein, the outer surface of the end cover is provided with threads or grooves.

[0014] Since this structure is a basic structure for connecting conductive wires in an inflatable device, it can be connected to many other structures. The connection methods can be threaded connection, snap connection, plug-in connection, etc. Threads or protrusions can be designed on the side of the substrate, the side of the three-dimensional structure, the side of the air pipe, the side of the end cover, the side of the column or the side of the cap to connect with the corresponding structure.

[0015] Beneficial effects: Compared with the traditional technology, the present invention has the following advantages:

[0016] (1) The present invention has an ingenious structural design. By separating the conductive structure from the inflatable structure, the purpose of simultaneously inflating and conducting electricity inside the device is achieved, and the device can be leak-proof for a long time.

[0017] (2) The present invention completes the conduction link without destroying the integrity of the metal sheet by welding two conductive wires to the two sides of the metal sheet, thereby ensuring that the inflatable device does not leak;

[0018] (3) The present invention can connect the power supply outside the inflatable device and connect the lamp or other power-carrying device to the wire inside, thereby reducing the occupied space inside the inflatable device. At the same time, the power supply can be controlled as needed, and it does not need to be powered on 24 hours a day. The power supply can be cut off at any time to save electricity.
