Description

Technical Field

[0001] The utility model relates to the technical field of powered air supply, and more specifically, to an intelligent adjustable powered air supply breathing system. Background Art

[0002] Powered air supply systems are widely used for respiratory protection of workers in polluted air environments. They can purify polluted air and deliver it to the user's mask, helmet or hood, etc. However, they still have some shortcomings in actual use, such as: the existing powered air supply system is generally composed of an air bin, a filter box, a breathing mask, etc. A motor is provided inside the air bin to draw air into the air bin and deliver it to the mask after purification by the filter box. In order to facilitate the use of the air supply breathing system at any time, a snap-on strap is generally provided on the outside of the air bin to fix the air bin to the user's waist, and some snap-on straps often need to be adjusted in length according to the user's waist circumference before use, but the strap adjustment process is relatively cumbersome, and the relative position of the buckle on the strap needs to be moved step by step, which affects the wearing of the powered air supply system to a certain extent.

[0009] It also includes a strap, a buckle, and a card box. One end of the strap is fixedly connected to the surface of the rotating rod, and the end of the strap away from the rotating rod is fixedly connected to the surface of the buckle. The card box is arranged on the surface of the flexible pad located on the left side of the wind bin body.

[0010] Wherein, it also includes an auxiliary component, and the auxiliary component is arranged on the surface of the mounting column.

[0011] Among them, the auxiliary component includes a fixed plate, a spring, a movable seat, a connecting rod and a brake disc, the fixed plate is fixedly connected to the surface of the mounting column, the top of the spring is fixedly connected to the bottom surface of the fixed plate, the bottom end of the spring is fixedly connected to the top surface of the movable seat, one side of the movable seat is in contact with the surface of the mounting column, the side of the movable seat surface opposite to the mounting column is fixedly connected to the bottom end of the connecting rod, the brake disc is arranged on the top of the connecting rod, the surface of the brake disc is in contact with the inside of the accommodating groove, and the side of the fixed plate surface away from the mounting column is slidably connected to the surface of the connecting rod.

[0012] The beneficial effects of the above technical solution of the utility model are as follows:

[0013] In the above scheme, the user touches the forward button to make the driving motor drive the rotating rod to rotate so as to extend the strap. After the strap is extended to a certain length, the strap can be wrapped around the waist so that the fitting plates on both sides of the air bin body can fit with the waist, and the buckle is buckled with the card box, and then the reverse button is touched to make the driving motor drive the rotating rod to reverse so as to retract the strap, so that the strap can fit tightly with the waist, that is, the wearing of the powered air supply system is completed. Therefore, by driving the strap to extend or contract by the driving motor, the strap can be quickly fitted to the user's waist, without gradually adjusting the relative position of the buckle and the strap, which greatly shortens the time for adjusting the strap, realizes the convenient wearing of the powered air supply breathing system, and improves the practicality of the device.

[0014] After the length of the strap is adjusted, the elastic action of the spring can drive the brake disc to abut against the inside of the accommodating groove. There is a large friction between the surface of the brake disc and the accommodating groove. Combined with the elastic structure of the spring, the top column can be braked, thereby fixing the length of the strap to prevent it from loosening when fixed on the user's waist, thereby ensuring the stability of the powered air breathing system when worn.
