Carbon dioxide generation device with low-oxygen protection

Abstract

The invention discloses a carbon dioxide generation device with low-oxygen protection. The device comprises a body shell, and a control module, a data collection module and an actuation module which are arranged inside the body shell, wherein the control module comprises a controller and a power supply module; the power supply module is used as a work power supply of the control module, the data collection module and the carbon dioxide generation device; the data collection module comprises an oxygen density sensor, and is used for detecting and collecting the environmental oxygen density value of the surrounding environment; the controller is used for reading the environmental oxygen density value, when the environmental oxygen density value is lower than a low-oxygen alarm threshold value, the actuation module is closed by the control module, and generation of carbon dioxide gas is stopped. Compared with an existing carbon dioxide generation device, the device has the advantages thatoxygen density real-time detection is added, and the carbon dioxide generation device under a low-oxygen state is automatically closed, so that the use safety of the carbon dioxide generation devicein a closed space is greatly improved, and a remarkable beneficial effect is achieved.

Description

technical field [0001] The invention relates to the field of modern agriculture, in particular to a carbon dioxide generator with hypoxia protection. Background technique [0002] Greenhouse planting is widely used in modern agriculture. Greenhouse planting keeps crops in a relatively closed place for a long time. The carbon dioxide concentration in the greenhouse changes greatly within a day. It drops to about 100ppm 2.5 to 3 hours after sunrise, which is only about 30% of the atmospheric concentration. In order to promote the photosynthetic ability of plants and increase the yield of plants, a certain amount of carbon dioxide can be added to the greenhouse, and this effect can be achieved through a carbon dioxide generating device. Special attention should be paid to the carbon dioxide generating device using the combustion method, which can increase the content of carbon dioxide in the greenhouse, but at the same time consume oxygen. Too low oxygen concentration will enda...

Problems solved by technology

[0006] Similar to it, the heating device using the combustion method is also a carbon dioxide generating device, which will generate a large amount of carbon dioxide gas and consume a large amount of oxygen. When the heating device is used in a closed room, if the indoor air cannot be kept unimpeded, there will be Risk of hypoxia; at the same time, insufficient oxygen concentration is prone to incomplete combustion and the risk of carbon monoxide poisoning
