Device for preventing odor invasion

Abstract

The invention relates to a device for preventing odor invasion. The device comprises an odor adjustable mask, a first control module, a wireless receiving module, a loudspeaker, a second control module, a wireless transmitting module and an odor detecting device; the first control module, the wireless receiving module and the loudspeaker are arranged on the odor adjustable mask; the second controlmodule, the wireless transmitting module and the odor detecting device are arranged on a range hood; the first control module is electrically connected with the wireless receiving module; the odor detecting device is electrically connected with the second control module; the second control module is electrically connected with the wireless transmitting module; the odor detecting device is used for detecting odor above a cooking bench; and when the odor detecting device detects that the concentration of the odor above the cooking bench reaches the preset threshold, the first control module controls the odor adjustable mask to adjust odor and controls the loudspeaker to make a sound. The device for preventing odor invasion can prevent kitchen workers from odor invasion, and has the advantages of automation and humanization.

Description

technical field [0001] The invention relates to the field of kitchen purification, in particular to a device for preventing odor attack. Background technique [0002] As condiments or ingredients, peppers and onions with a pungent smell play an important role in the cooking process of dishes, and because of the ever-changing delicacies they process, they become indispensable in the kitchen. Taking pepper as an example, pepper contains capsaicinoids (Capsaicinoids, composed of fourteen kinds of capsaicinoids), and the main capsaicin is dihydrocapsaicin (8-methyl-N-vanillyl nonamide, Dihydrocapsaicin). Under the condition that the temperature of vegetable oil and animal oil is higher than 280°C, capsaicin volatilizes continuously along with oil fumes, causing a pungent smell to accumulate in the kitchen. [0003] The kitchen purifier of prior art, for example, CN202757174U has announced a kind of range hood oil fume purifier 1, please combine figure 1 It should be understood...

AI Technical Summary

Problems solved by technology

[0004] However, the prior art fume purifiers for range hoods not only cannot effectively purify the fume, but also cannot remove the volatilized odor during the cooking process, resulting in the mixing of gaseous pollutants (VOCs) with a particle size of less than 5 microns into the air, thereby forming Spicy and pungent aerosols, floating in the atmosphere for a long time (≥30 minutes), affect the kitchen environment. When chefs or kitchen staff are in it, they will be attacked by the smell and cause symptoms such as coughing
