[0020] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0021] Embodiment 1

[0022] like Figure 1-2The automatic pressure regulating device for an oxygen concentrator comprises an air supply pipe 1, a branch pipe 2 is arranged above the air supply pipe 1, a counterweight block 4 is slidably connected inside the branch pipe 2, and a pressure rod 5 is fixedly connected above the counterweight block 4; the branch pipe 2 is connected to a shunt pipe 8 arranged horizontally, and the other end of the branch pipe 2 is connected to an exhaust hole 10; the branch pipe 2 is sleeved with a sliding sleeve 7, and the sliding sleeve 7 is connected to an adjusting mechanism; the sliding sleeve 7 is connected to the air supply pipe 1 through the adjusting mechanism; the adjusting mechanism comprises a sliding rod 6, the sliding rod 6 is hinged to a first connecting rod 3, the first connecting rod 3 is hinged to a second connecting rod 9, and the second connecting rod 9 is hinged to a first connecting rod 3. A baffle 11 is connected; a plurality of support rods 13 are fixedly connected above the air pipe 1, and the support rods 13 connect the first connecting rod 3 and the second connecting rod 9; an annular plate is fixedly connected to the upper end of the baffle 11, and a spring 14 is arranged between the annular plate and the air pipe 1; a through hole is opened in the air pipe 1, and the through hole is slidably connected to the baffle 11; the pressure rod 5 is in the shape of a hook, the pressure rod 5 is connected to a pressure plate 5-1, and the sliding rod 6 is connected to a force plate 6-1, and the pressure plate 5-1 cooperates with the force plate 6-1; the air pipe 1 is connected to a breathing tube 12; the pressure plate 5-1 and the force plate 6-1 have the same shape and size.

[0023] This embodiment also provides a method for using the automatic pressure regulating device of an oxygen concentrator, comprising the following steps:

[0024] Step 1: Place the device in a suitable location;

[0025] Step 2: When the internal air pressure is too high, the counterweight 4 will rise; when the counterweight 4 rises to the point where the shunt pipe 8 is connected to the gas pipe 1 through the branch pipe 2, the gas in the gas pipe 1 will pass through the branch pipe 2, then through the shunt pipe 8, and finally through the exhaust hole 10 to exhaust, thereby reducing the air pressure in the gas pipe 1 and resetting the counterweight 4;

[0026] Step three: When the internal air pressure is too low, the counterweight 4 moves downward as the air pressure decreases. When the pressure plate 5-1 contacts the force plate 6-1, the sliding rod 6 descends along with the counterweight 4. As the sliding rod 6 descends, the left end of the first connecting rod 3 descends and the right end rises, thereby driving the left end of the second connecting rod 9 to rise and the right end to descend, thereby causing the baffle 11 to descend along the through hole of the air pipe 1, thereby reducing the contact area between the air pipe 1 and the breathing tube 12, thereby achieving the effect of increasing the air pressure; when the air pressure returns to normal from low, the counterweight 4 rises and the baffle 11 is quickly reset under the action of the spring 14.

[0027] It can be seen from this embodiment that the counterweight 4 is raised and lowered according to the internal air pressure, thereby automatically adjusting the air pressure and keeping the air pressure stable, thereby avoiding discomfort caused by changes in air pressure during use for patients.

[0028] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
