Demonstration device and application method thereof

Abstract

The invention discloses a demonstration device and method, and the device is used for an air conditioner with an oxygen adding and fresh air function, and the device comprises a transparent shell which is provided with an inner cavity, wherein the upper end of the transparent shell is provided with an opening communicated with the inner cavity; a fresh air connecting port which is located in the side wall of the lower portion of the transparent shell and used for inputting oxygenated fresh air into the inner cavity; a gas dispersing part which is arranged at the lower part of the inner cavity and is used for dispersing the oxygenated fresh air input from the fresh air connecting port; a sample strip support which is arranged above the gas dispersing part and used for being fixedly connected with a demonstration sample strip, wherein the oxygen index of the demonstration sample strip is larger than 21% and smaller than 30%. In using, the demonstration sample strip is ignited to carry out flame combustion (the demonstration sample strip cannot carry out flame combustion in natural air), the transparent shell can enable consumers to visually observe the flame combustion of the demonstration sample strip, it is proved that the oxygen content of the oxygenated fresh air is higher than that of the natural air, the fresh air oxygenation effect of the air conditioner is promoted, and the sales volume is increased.

Description

technical field [0001] The invention relates to the technical field of oxygen concentration detection, in particular to a demonstration device and method for demonstrating the oxygen addition effect of fresh air of an air conditioner. Background technique [0002] At present, some air conditioners have the function of adding oxygen to the fresh air, increasing the oxygen content of the fresh air, which is of great benefit to improving the health of the elderly, pregnant women and rehabilitation groups. However, oxygen is colorless and odorless, and changes in a certain concentration range are not easy to perceive. There is no simple and intuitive way to display the function of oxygenated fresh air for product function promotion. However, through sensor detection, the method of displaying oxygen concentration changes on the display screen is not intuitive enough, and consumers do not trust electronic display methods without life experience.
