A plurality of fixed columns are fixedly connected to the front end of the fixed cylinder, and fans are fixedly connected to the inner sides of the plurality of fixed columns, and the activated carbon filter is located on the inner side of the HEPA filter and the fan.

[0007] Furthermore, the control panel is electrically connected to the wind turbine.

[0008] Furthermore, one end of the two fixing belts are respectively fixedly connected with buckles.

[0009] Furthermore, the protection pad is made of rubber material.

[0010] Compared with the existing technology, the utility model has the following advantages: the utility model provides a fan and a control panel, the control panel is electrically connected to the fan, and the gear of the fan is controlled by the control panel, thereby adjusting the speed of the external air circulation. In addition, the utility model provides an activated carbon filter and a HEPA filter, and the external air drawn in is filtered through the activated carbon filter to filter the dust particles, and then further filtered through the HEPA filter. The HEPA filter can also absorb the odor in the air, ensuring that the air drawn into the human body is non-toxic and harmless. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings, wherein the same parts are represented by the same reference numerals.

[0015] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0016] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0017] like Figure 1 to Figure 2As shown, a regulated air respirator comprises a respirator shell 1, an air purification device 2 is provided on one side of the respirator shell 1, a control panel 4 is fixedly connected to one side of the respirator shell 1, and a protective pad 5 is fixedly connected to one side of the respirator shell 1. The protective pad 5 makes the worker more comfortable to wear. Fixed belts 6 are respectively fixedly connected to both sides of the respirator shell 1. The two fixed belts 6 are respectively extensible and elastic, which are convenient for adjusting and fixing people with different head shapes. A glass eye mask 3 is fixedly connected to one side of the respirator shell 1. The glass eye mask 3 is made of transparent glass. When the outside air is turbid, the glass eye mask 3 can protect the worker's eyes.
