Semiconductor thermoelectric sheet protective mask

Abstract

The invention belongs to the technical field of masks and specifically discloses a semiconductor thermoelectric sheet protective mask. The semiconductor thermoelectric sheet protective mask comprisesa mask body, a filter box system arranged on the mask body and an electronic control system arranged on the filter box system. A filter box body is internally provided with an air inlet section and anair outlet section which are parallel up and down. A first air guide plate and a second air guide plate are arranged in the air inlet section. The filter box body is internally further provided witha semiconductor thermoelectric sheet electrically connected with the electronic control system. The semiconductor thermoelectric sheet protective mask divides inhaled air inlet flow into an air flow heating section, an air flow cooling section and a flow stabilization adjusting section. The hot end of the semiconductor thermoelectric sheet is arranged in the air flow heating section. The cold endof the semiconductor thermoelectric sheet is arranged in the air flow cooling section. An air feeder is arranged at an air inlet of the air flow heating section and is electrically connected with theelectronic control system. An exhaust fan is arranged at an air inlet of the air outlet section. A one-way breather valve is arranged at an air outlet of the air outlet section. The semiconductor thermoelectric sheet protective mask is high in comfortability, reasonable in structure and capable of effectively improving the quality of inhaled air.

Description

technical field [0001] The invention belongs to the technical field of masks, and more specifically relates to a semiconductor thermoelectric sheet protective mask. Background technique [0002] With the rapid development of society, the increasingly harsh atmospheric environment has seriously affected people's health, life, and travel, causing a lot of inconvenience to our lives. For people's health, many kinds of filter mask machines have appeared on the market Virus protection, to prevent viruses or bacteria from harming people's health. At present, there are ordinary, sterilized, cotton, activated carbon masks and N95, KN90 masks on the market. However, ordinary, cotton, and activated carbon masks are mainly multi-layered and cannot be sterilized. The inside of the mask is wet, which affects normal use and protection. [0003] In the prior art, some protective masks that combine the device for disinfecting bacteria with the existing filter masks have also been proposed...

Problems solved by technology

At present, there are ordinary, sterilized, cotton, activated carbon masks and N95, KN90 masks on the market. However, ordinary, cotton, and activated carbon masks are mainly multi-layered and cannot be sterilized. The inside of the mask is wet, which affects the normal use and protection

[0003] In the prior art, some protective masks that combine the device for disinfecting bacteria with the existing filter masks have also been proposed. However, they are generally designed with the air inlet and the air outlet integrated, which easily causes the backflow of the exhaled gas. It is beneficial for human body monitoring, and at the same time, the backflow of gas causes the human body to inhale more carbon dioxide, which brings a series of complications

Secondly, in the existing technology, the technology of applying semiconductor thermoelectric sheets to masks for heating and disinfection is not perfect, such as difficult to control the temperature and insufficient heating to achieve the antivirus effect
