Embodiment Construction

[0030] An embodiment of the present invention is described below with reference to accompanying drawing:

[0031] exist figure 1 Among them, the small air pump is a pressure-resistant structure with an extremely compact internal space. An improved threaded tube air pump or piston air pump can be used. The hard force-bearing surface at the top of the small air pump is installed on the upper side of the elastic body, and it is connected to the atmosphere through the one-way valve 1. connected. The bottom surface of the small air pump is connected with the hard stress surface at the top of the large air pump, and a check valve (5) is arranged in the middle to communicate with the two air pumps. Atmospheric pump can adopt screw pipe air pump, and atmospheric pump is communicated with elastic body by one-way valve (6), and one-way valve (6) can be installed on the side or bottom surface of atmospheric pump, and the bottom surface of atmospheric pump is installed on the inner lowe...

Abstract

The invention discloses a device installed in an elastomer in confined space, which aerates air for the confined space by deformation generated by repeated constant pressure and realizes constant pressure. The device is composed of a large air pump and a small air pump which are connected in series; the compression area of the small air pump is smaller than that of the large air pump; and in practical work process, the two air pumps work together or work alternatively, so as to realize the aeration of high-pressure air in the elastomer and stops charging air under a constant pressure. The final aeration air pressure can be regulated by regulating the starting air pressure of the single-way valve at the output end of the large air pump.

Description

Technical field [0001] The invention relates to a device installed in an elastic body in a closed space to inflate the elastic space and realize constant pressure through deformation caused by repeated constant pressure. Background technique [0002] At present, known elastic bodies in confined spaces include: tires, balls, swimming rings, etc. There are several common ways to inflate them: 1. Inflator; 2. Electric air pump; 3. Mouth blowing. Regarding the technology of automatically achieving inflation and constant pressure through built-in devices, the search found that many prior technologies have been disclosed. For details, please refer to the following comparison: [0003] Reference document 1: A Chinese patent document with the patent number 89211618.8 discloses a design scheme, which has the following characteristics: 1. The inflation device is placed inside the tire; 2. It consists of a pump riser and an air pump ; 3. Adopt a first-stage air pump structure; 4. Infl...
