Energy-saving intelligent deodorization device for public washroom

Abstract

The invention discloses an energy-saving intelligent deodorization device for a public washroom, which comprises a deodorization device main body. A galvanized sheet shell is arranged outside the deodorization device main body; thedeodorization device main body is internally provided with a variable-frequency fan, a data acquisition and control system, an air freshener spraying device, an activated carbon module and a photocatalytic oxidation deodorization device; the data acquisition and control system is composed of a Zigbee wireless data acquisition device and an intelligent adjustment control device; the air freshener spraying device is composed of a sprayer, a liquid storage tank and an adjustable valve; and the photocatalytic oxidation deodorization device is composed of a lampshade,a lamp holder, a variable-frequency ultraviolet lamp tube and a catalyst TiO2. Real-time intelligent monitoring is achieved, people and the deodorization device can know the odor concentration, temperature and humidity in the toilet, the real-time monitoring value of the odor concentration is compared with the toilet odor concentration standard, and the optimal air speed of the deodorization device, the optimal spraying amount of the air freshener and the optimal electric lamp illuminance are given.

Description

technical field [0001] The invention relates to the field of air purification, in particular to an energy-saving intelligent deodorizing device for public toilets. Background technique [0002] The toilet is an essential and important place in people's daily life. The toilet will produce a large amount of malodorous gases such as ammonia or hydrogen sulfide. These malodorous gases will stimulate the human body's sense of smell and endanger human health. Most of the deodorizing devices currently on the market simply deal with odors all the time, and cannot match the air volume of the deodorizing devices well according to the actual odor environment, so they often generate too much unnecessary fan energy consumption; contrary to today's Energy-saving requirements in a large environment. In addition, because there is no monitoring of the odor concentration in the toilet and the lack of objective and practical judgment indicators, people are still confused when choosing the air...

Most of the deodorizing devices currently on the market simply deal with odors all the time, and cannot match the air volume of the deodorizing devices well according to the actual odor environment, so they often generate too much unnecessary fan energy consumption; contrary to today's Energy saving requirements in a large environment

In addition, due to the lack of monitoring of toilet odor concentration and the lack of objective and practical judgment indicators, people are still confused when choosing the air volume gear, and cannot have a rational understanding of the toilet environment

[0003] In order to improve the air quality of the bathroom, a Chinese patent has disclosed "an intelligent multifunctional toilet deodorizing device" (China, announcement number CN110387930A, announcement date 2019.10.29), which proposes an intelligent deodorizing device that can effectively ensure The air quality of toilets or squatting toilets, but there is no monitoring of the concentration of odorous gases. The concentration of odors in toilets is not constant, and the amount of odorous gases processed by the device cannot be adjusted according to the actual odorous environment. Therefore, its high energy consumption makes it used in public toilets. Restrictive and uneconomical for public restrooms requiring multiple deodorizers

A Chinese patent once disclosed "a deodorizing system for public toilets of the Internet of Things" (China, announcement number CN110616783A, announcement date 2019.12.27), which proposed a deodorizing system for toilets that can monitor the concentration of toilet odors, but it has not been realized Intelligent adjustment requires a large labor cost to maintain
