Description

A ceiling-mounted humidifier

technical field

The invention belongs to the field of air purification, and in particular relates to a ceiling-mounted humidifier.

Background technique

In modern engineering design, a good environment brings benefits to the human body and products, and the control of the environment in workshops, production workshops, warehouses, offices and homes has been paid more and more attention by people. Three basic indicators of environmental control: air quality, temperature and relative humidity. In general, temperature is the most direct influence on how people feel about their living environment. Similarly, humidity will also have an impact on people's lives and health. With the improvement of people's living standards, the widespread use of air conditioners also leads to the breeding of air-conditioning diseases such as tight skin, dry tongue, cough and cold, and long-term use of heating indoors in winter will aggravate the loss of water, and the environmental humidity will be lower, which is more exacerbates people's discomfort. Science has proved that air humidity is closely related to human health and daily life. Medical research has shown that when the room humidity reaches 45-65% RH and the temperature is 20-25 degrees, people's body and thinking are in a good state, and ideal results can be obtained regardless of work or rest. In addition, proper relative humidity control is also one of the important factors for energy saving and work efficiency of the plant.

The suspended ceiling refers to a decoration of the top decoration of the living environment of the house. Simply put, it refers to the decoration of the ceiling, which is one of the important parts of interior decoration. It has the functions of heat preservation, heat insulation, sound insulation and sound absorption. hidden layer. Because the suspended ceiling has the above functions, it is more and more widely used in the field of decoration. At the same time, due to its good concealment, some necessary electrical equipment is increasingly arranged on the ceiling structure in modern architectural engineering design to expand the practical area. Ceiling air conditioners, ceiling air humidifiers and other equipment came into being.

Many ceiling-mounted air humidifiers have also been developed in the industry. For example, CN 205860319 U discloses a humidifier, which can be installed in a stainless steel box and used as a ceiling-mounted humidifier; CN 108870611 A discloses a ceiling-mounted humidifier, which is The cooperative relationship between the sliding rod and the action groove can adjust the position of the sliding rod on the horizontal support plate to change the distance between the sliding rods, adjust the coverage area of the aromatherapy board unit, and then realize the adjustment of the aromatherapy concentration; CN 206890732 U discloses a An integrated ceiling humidifier, which greatly improves the humidification effect without increasing the water flow through the pressurization device. Although the above humidifiers can effectively humidify the air, they all use water tanks to provide water sources. The water tanks store water sources for a long time. Over time, there will inevitably be pollution. The humidifiers are used for a long time, which will cause circulatory pollution, which may even cause serious pollution. endanger the safety of the user. Although the "Korean humidifier fatality incident" that broke out in 2011 was mainly due to the fact that the humidifier disinfectant contained PHMG (polyhexamethylene biguanide hydrochloride), it is undeniable that the circulation pollution of the water tank aggravated the deterioration of the situation. .
