Experiment cabin system capable of adjusting atmospheric environmental pressure

Abstract

The invention provides an experiment cabin system capable of adjusting atmospheric environmental pressure. The system is characterized by comprising an experiment cabin arranged in a constant-temperature constant-humidity environmental chamber and a positive and negative pressure generation unit, a ventilation adjusting unit, an air purification unit, a meteorological sensor and a system control unit controllable both in and out of the cabin, which are arranged to be communicated with the cabin. Compared to the prior art, the invention has the following advantages: 1, the system can realize control of the environment condition of atmospheric pressure in research and experiments on tobacco and is applicable to control of atmospheric pressure in most regions where people live; 2, the inner space of the system is great, which enables a plurality of staff to simultaneously carry out experiments; 3, the comprehensive air purification unit is provided in the cabin, which enables collection and purification of harmful gas generated after combustion of tobacco to be realized; 4, the system is simple to operate and enables single-key operation and comprehensive information prompting to be realized in normal usage; and 5, security design and humanized design of the system are considerate, an automatic safety device is arranged in the cabin, and hand-operated safety devices are arranged in and out of the cabin.

Description

[0001] technical field [0002] The present invention relates to an experimental cabin system with adjustable atmospheric environment pressure suitable for the standardization research of tobacco products, tobacco product quality evaluation and tobacco processing technology research. The stable small environment required for specific experiments, the atmospheric pressure adjustment range is 80000Pa~105000Pa. [0003] Background technique [0004] Chinese patent (ZL200620134989.6) discloses an environmental tobacco smoke experimental chamber for the research on the quality difference of tobacco products and the evaluation of related standards, but this experimental chamber can only control the temperature and humidity conditions, and lacks the atmospheric pressure environment. Condition control function. [0005] Due to the influence of local ambient atmospheric pressure, many relevant standards and technical specifications of tobacco technology and tobacco products are dif...

Problems solved by technology

[0004] Chinese patent (ZL200620134989.6) discloses an environmental tobacco smoke experimental chamber for the research on the quality difference of tobacco products and the evaluation of related standards, but this experimental chamber can only control the temperature and humidity conditions, and lacks the atmospheric pressure environment. condition control function

[0006] The current status quo is that related work can only rely on staff to carry relevant instruments and equipment to repeat experiments in different atmospheric pressure environments, which requires a lot of manpower, material resources and time. If it is necessary to supplement or verify the experiment, it is more difficult to choose the same as the original experiment. Atmospheric ambient conditions

Especially in some experimental items that require sensory evaluation, the differences are more obvious under different atmospheric pressure environmental conditions, and the correct judgment cannot be obtained through data analysis and processing, and it is difficult to obtain reproducible test results

[0007] In other fields, like a pressurization chamber or a decompression chamber, although there are conditions in which the air pressure can be adjusted in the chamber, there are: 1. It is impossible to meet the requirements of the tobacco experimental research on the precise adjustment and strictness of the atmospheric pressure in the chamber within the experimental requirements. 2. Unable to meet the uniform airflow in the cabin required by some tobacco experimental research; 3. Unable to collect and purify the harmful gases after tobacco combustion, and unable to meet the requirements of long-term tobacco combustion experiments for experimenters 4. It cannot meet the needs of the experimenters in the cabin to adjust the atmospheric pressure in the cabin within the range required by the experiment at any time according to the needs during the tobacco experiment research.

In addition, it cannot meet the needs of multiple staff members to carry out experimental work at the same time and the placement of tobacco experimental instruments and equipment.

In conclusion, the pressurized or decompressed chambers that exist in other fields cannot satisfy the application in the field of tobacco research
