Embodiment 1

[0050] Embodiment 1. A head-mounted portable electric air-purifying respirator (abbreviated as a respirator). The shape and structure of the respirator and the design of the connection of parts conform to the shape of the human face model, and the overall use of lightweight materials is suitable for wearing, such as Figure 1-3 As shown, it includes the host 1, the right air duct 2, the mask 3 and the left air duct 4. When in use, the mask 3 faces forward and fits closely with the lips and nose of the user. The host 1 is located behind the head and neck and is connected to the user's head The position of the occipital bone is closely fitted, and the host 1, the right air channel 2, the mask 3 and the left air channel 4 are sequentially sealed and connected to form a circular air flow channel. In the following description, the inner ring of the circular ventilator and the head is the inner ring, and the outer ring is the outer ring.

[0051]The host 1 is a nearly semicircular a...

Abstract

The head-mounted portable electric air purification breathing machine comprises a main machine, and the main machine is sequentially connected with a right air channel, a mask and a left air channel in a sealed mode to form a circular-ring-shaped air flow channel; a turbofan, a controller and a battery are arranged in an inner cavity of the main machine, an induction guide pipe is arranged in the left air guide pipe, the controller comprises a micro differential pressure sensor, an inverter and a microcontroller, and the microcontroller comprises a micro differential pressure closed-loop system control unit. The invention further discloses a control method thereof, the micro differential pressure closed-loop system control unit is used for controlling the rotating speed of the fan motor and automatically adjusting the flowing speed of the airflow input into the mask, and the pressure in the mask is kept at the normal positive pressure level, so that a user can freely and easily breathe.

Description

technical field [0001] The invention relates to the technical field of filtering breathing masks, in particular to a head-mounted portable electric air-purifying respirator and a control method. Background technique [0002] In the process of modernization, human's demand for energy is constantly increasing. For related energy mining operations, it is inevitable that workers need to be exposed to the harsh environment of the construction site. The existing domestic ventilators have problems such as untimely adjustment, unsmooth breathing experience, loud noise, high price, inconvenient to carry, and limited applicable occasions. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a head-mounted portable electric air-purifying respirator and a control method, which are used to automatically control the speed of the turbo blower according to the pressure value in the mask of the respirator, and continuously and efficie...
