Portable air cleaner

Abstract

The invention provides a portable air cleaner, aims to solve the problem that the conventional respirators are single in function and unpractical, and relates to the technical field of air purification. The portable air cleaner comprises a cleaning main frame and a respiration nasal mask, wherein the cleaning main frame and the respiration nasal mask are connected through a flexible duct; the interior of the cleaning main frame is divided into a pressure-boost filter cavity, a primary air storage cavity and a secondary air storage cavity; a filter and a booster pump are arranged in the pressure-boost filter cavity; a negative ion generator is arranged in the primary air storage cavity; and a refrigeration and heating device, a pressure sensor and a temperature sensor are arranged in the secondary air storage cavity. The portable air cleaner has the advantages of simple structure, small size and portability; a jet pump is arranged in the cleaner to achieve positive-pressure air supply, the air supply volume is large, and the air cleaner can meet the use requirement of a user in exercise; the negative ion generator and the refrigeration and heating device arranged in the air cleaner can further improve the air quality; and further, a display screen can display the key parameters such as the flow rate, the air pressure, the temperature, the residual electric quantity and the like, and has a warning function, so that the user can operate accurately and use the air cleaner safely.

Description

Technical field: [0001] The invention relates to the technical field of air purification, in particular to a portable air purifier. Background technique: [0002] Medical respirators (such as CPAP or BIPAP respirators) are used in hospitals and households, but currently there is no central gas supply for common medical respirators, which are mainly provided with a filter and a high-speed compressed air supply device in a housing. And a breathing tube and a breathing mask are connected behind the high-speed air supply device, wherein the high-speed air supply device is composed of blower or turbocharger, so the air in the environment will be sucked into the respirator through negative pressure, so that the patient The air can be inhaled into the patient's mouth, nose and lungs through the breathing circuit to achieve the purpose of breathing. The positive pressure of the respirator with this structure is difficult to control. [0003] Commonly used medical respirators witho...

Problems solved by technology

The positive pressure of the respirator with this structure is difficult to control

[0003] Commonly used medical respirators without a central gas supply use filters to filter suspended particles in the ambient air. After a period of use, the possibility of damage to the filter in the respirator increases, resulting in the inability to ensure the clean quality of the filtered air

It is also impossible to warn the user to clean and replace the filter screen in time, so the continuous use of commonly used medical respirators will increase the possibility of dirty air entering the human body. Sustained positive pressure provides dirty air and suffers from it

[0004] In addition, the existing medical respirator has a single function and can only filter the air, which cannot further improve the air quality, nor can it change the temperature of the air that is too cold or too hot in extreme environments.
