Problems solved by technology

[0005] At present, whether it is a domestic ventilator or an imported ventilator, if there is a power failure, there is no function to wake up the user. At this time, the sleeping user can only get oxygen through the small air outlet hole on the mask, that is, Oxygen supply is greatly reduced, which can easily cause users to suffocate, so it is necessary to increase the power failure wake-up function according to the actual electricity consumption in rural areas

Embodiment 1

[0039] see figure 2 .

[0040] We provide a streamlined version of a water column manometric mask type continuous positive pressure PM2.5 filter for personal use;

[0041] The simplified version is based on the household ventilator, in order to reduce the factory cost and future maintenance costs, the pressure sensor 6 and the corresponding electromechanical components, the flow meter 8 and the corresponding electromechanical components, the humidifier 13 and the heating cable 9 are also canceled. User requirements are also canceled in this embodiment as an optional part; but this embodiment adds a precision filter 5 for filtering PM2. A battery 16, an alarm 20 and corresponding circuits are provided.

[0042] Additional component description: The precision filter 5 for filtering PM2.5 is a melt-blown PP cotton filter element (referred to as: PP cotton filter element), which is formed by melting polypropylene material at high temperature and spraying it into filaments to a ...

Embodiment 2

[0047] see figure 1 .

[0048] On the premise of the simplified version, we also provide a full version of the configuration:

[0049] This embodiment discloses a personal water column manometer mask type continuous positive pressure PM2.5 filter; on the basis of a household ventilator, a precision filter 5 for filtering PM2.5 is added in the air circuit, and the U-shaped pressure gauge 14 and power failure wake-up function, this includes increasing battery 16 and alarm 20 and corresponding circuit, the description of these increased devices is the same as embodiment 1.

[0050] The description of the connection relationship of each component in this embodiment, according to the airflow direction, is as follows: coarse inlet filter 1 → micro centrifugal fan 2 → pressure test nozzle 3 → filter housing 4 → precision filter 5 → air pressure sensor 6 → U-shaped pressure gauge 14→flow meter 8→humidifier 13→silicone hose 11→face mask 12→face mask air outlet 11; when the heating ca...

Embodiment 3

[0054] This embodiment discloses a water column pressure measuring mask type continuous positive pressure PM2.5 filter for personal use in a dusty environment.

[0055] This embodiment is basically the same as Embodiment 1. In order to prolong the service life of the precision filter, a flexible pipe is used between the inlet coarse filter 1 and the micro-shaped centrifugal fan. The length of the flexible pipe can keep the air inlet away from the dust environment; the other difference is that the control The device 18 as a whole can be powered by a battery, so as to adapt to the mining environment without power supply.

Abstract

The invention relates to the technical field of air pollution control and health care, in particular to a water column pressure-measuring mask-type continuous positive pressure PM2.5 filter for personal use. The water column pressure-measuring mask-type continuous positive pressure PM2.5 filter comprises a coarse filter body, a miniature centrifugal fan, a precision filter body, a U-shaped pressure gage and a mask. The precision filter body is an annular columnar filter, and a purification chamber is formed in the center of the precision filter body. A filter shell is arranged outside the precision filter body, and the coarse filter body communicates with the miniature centrifugal fan. The miniature centrifugal fan communicates with the filter shell, and the mask communicates with the purification chamber in the center of the precision filter body. The water column pressure-measuring mask-type continuous positive pressure PM2.5 filter further has the outage wake-up function to improvesafety and can further be applied to the dust operating environment to prevent silicosis.

Description

technical field [0001] The invention relates to the technical field of air pollution control and health care, in particular to a water column manometric mask type continuous positive pressure PM2.5 filter for personal use. Background technique [0002] From the point of view of expert purification, the current household air purifiers are actually very unscientific, it is difficult to quickly and effectively eliminate PM2.5, and the indoor and outdoor air is not easy to circulate, which is not conducive to hygiene and health. However, the mask-type air filter can achieve Purification level, and energy saving and high efficiency. [0003] There are more and more obese people in China, and many of them have apnea syndrome. However, due to economic and conceptual problems, the vast majority of them are not equipped with ventilators, which will cause brain and brain damage. Tissue hypoxia can lead to cardiovascular disease, affecting work quality and traffic safety. Surgical tr...
