Description

Technical Field

[0001] This utility model relates to the field of air pump technology, specifically to a dual air pump structure that can be quickly inflated. Background Technology

[0002] An air pump is a device that removes or adds air to a closed space. Air pumps are mainly divided into electric air pumps, manual air pumps, and foot-operated air pumps. Electric air pumps are powered by electricity, continuously compressing air to generate pressure. They are mainly used for air inflation, sewage treatment, electroplating aeration, biogas digester aeration, tunnel ventilation, etc.

[0003] Currently, existing air pumps are relatively slow to inflate, requiring a long time to inflate; moreover, they have high power consumption and are prone to noise and heat generation during use, causing significant inconvenience to users. Utility Model Content

[0004] The purpose of this invention is to provide a dual-pump structure that can be quickly inflated, in order to solve the problems mentioned in the background art, such as the slow inflation speed, high power consumption, and the tendency to generate noise and heat.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual-pump structure for rapid inflation, comprising a lower cover, an AC air pump unit installed inside the lower cover, the AC air pump unit including an AC compressor, a mounting plate, a U-shaped frame and a snap-fit ​​frame, four U-shaped frames being arranged in two staggered groups integrally injection molded on the surface of the lower cover, with a mounting plate inserted between adjacent U-shaped frames, and an AC compressor mounted on the surface of the mounting plate, and a snap-fit ​​frame integrally injection molded on the surface of the lower cover between the two U-shaped frames, and after the mounting plate is inserted into the U-shaped frame and installed in place, the bottom of the mounting plate and the snap-fit ​​frame are fastened and fixed together.

[0006] Preferably, a mounting cavity is provided on one side of the lower cover surface, and a display screen is installed inside the mounting cavity; an air pipe mounting groove is installed on one side of the lower cover, which is used for the installation of the air pipe connector.

[0007] Preferably, the lower cover has hanging grooves at both ends on the side away from the mounting cavity, which facilitates the hanging and installation of the lower cover; six upper cover mounting posts are integrally injection molded at the edges on both sides of the lower cover, which are used for the installation and fixing of the upper cover.

[0008] Preferably, the lower cover surface is integrally injection molded with a buckle frame located between the two U-shaped frames, and after the mounting piece is inserted into the U-shaped frame and installed in place, the bottom of the mounting piece is fastened and fixed to the buckle frame.

[0009] Preferably, four sets of circuit board mounting posts are integrally injection molded on one side of the interior of the lower cover, which facilitates the installation of the circuit board.

[0010] Preferably, four sets of battery mounting posts are integrally injection molded on the side of the lower cover away from the circuit board mounting posts, which facilitates the installation of the battery.

[0011] Preferably, the DC air pump unit includes a DC compressor and a compressor mounting column. The compressor mounting column is integrally injection molded inside the lower cover, and the DC compressor is mounted on the surface of the compressor mounting column.

[0012] Compared with existing technologies, the beneficial effects of this utility model are as follows: This dual-pump structure for rapid inflation, by setting up a DC pump section and a DC pump, allows for quick installation of the AC compressor. During implementation, the AC compressor is mounted on a mounting plate, which is then inserted between two U-shaped frames. Since there are two sets of U-shaped frames, the mounting plate can be inserted into the corresponding U-shaped frame as needed. After insertion, the bottom of the mounting plate will interlock with the snap-fit ​​frame, thus achieving rapid installation of the AC compressor. This solves the problem of using bolts for fixing in existing technologies and reduces the labor intensity during AC compressor installation. This utility model, through its DC pump section, enables rapid inflation, more than twice as fast as conventional methods. Furthermore, during the pressure holding phase with small pressure fluctuations, the DC compressor can be shut down via a circuit board, reducing power consumption and minimizing noise and heat generation.
