The invention relates to the technical field of household appliances, specifically relating to a spraying fan.
Along with the development of science and technology and the advancement of society, multifunctional electric products are more and more popular with people, and the spraying fan is one of them. The traditional electric fan drives fan blades through the rotation of a motor to generate air flow so as to achieving effects of ventilation and cooling, but it has disadvantages of single function of blowing and causing indoor air drying after long-time use, thereby affecting human health. Therefore, people design various spraying fans, and can use a spraying humidifier to humidify air while blowing air, so that on one hand, heat is taken away by water evaporation to facilitate the air cooling, and on the other hand, moisture in the air can be supplemented in time. However, these designs suffer from the following disadvantages: 1. the humidifying spray function and the fan cannot be used separately. 2. The water tank inlet is little, making it difficult to add water and clean the water tank, which tends to accumulate the bacterium, and further influences the health in the long-term. 3. The water tank is designed in the product bottom which needs to be taken out when adding water and put back after adding water, which is quite complex. 4. The water is guided into the anatomization piece by adopting the water absorption cotton strip to absorb water, which can become mildewed and accumulate bacteria after being used for a long time, which is not beneficial to human health. 5. The air outlet window of the fan and fan main part adopt tight and fixed structure, which can not be dismantled, leading to difficult in cleaning fan blades and dust accumulation of air outlet window.
Aimed at the shortcomings in the prior art, the invention provides a spraying fan which is convenient to use, easy to clean and operate.
