No need to install a cooling air-conditioning fan to spray water-cooled ice mist. A small fan with a neck and a small fan with a waist can blow all over the body. The water-cooled mattress makes the summer night cool... The summer is hot, and a new cooling artifact comes on stage. The hottest month of the year has come. The temperature across the country has exceeded 30 ℃, and in some areas the temperature has even reached more than 40 ℃. You will sweat profusely after a few steps outside. Because of their portability, the neck mounted small fans and hand-held small fans have become good cooling objects in summer in recent years. This year, new "upgraded" products have come out. For dormitories or rental houses without air conditioners, electric fans and air circulation fans become "just needed". The portable and storable ceiling fan is more flexible. Its shape is similar to the traditional ceiling fan. Hanging on the top of the head can provide a soft natural wind feeling, which is not easy to catch cold and will not feel headache after blowing for a long time. The double blades can gather the air flow more intensively, and the air output is large and quiet at the same time. In addition to selecting the wind power, it can also be remotely controlled by infrared, which can be turned on and off at any time. The one day endurance can not only meet the daily needs, but also meet the use of the whole day when camping. The small waist mounted fan designed for high-temperature workers has been upgraded this year. The double tuyere design has more sufficient wind power. The high-capacity battery can provide long-term endurance. When it is used, it is hung below the waist hem, and the air outlet faces the clothes. The strong wind power supply makes the body cool quickly. It is more suitable for outdoor workers, takeaway delivery, logistics handling and indoor workers who cannot install air conditioners, as well as outdoor sports enthusiasts such as fishing and mountaineering. The desktop cooling air-conditioning fan can be used as an ordinary fan, or it can be combined with the ice water to blow out the ice mist for rapid cooling. When in use, the refrigerated mineral water bottle can be installed on the machine, or ice can be directly added to the machine. After testing, when the room temperature is 36 ℃, the fan can drop 1 ℃ to 3 ℃, add water can drop 3 ℃ to 7 ℃, add ice water can drop 7 ℃ to 12 ℃. Water cooled mattresses make people who like to use mats more comfortable. When in use, add water to the circulating water return device outside the mattress itself. It can not only provide cooling for the mattress, but also is a water-cooling fan, bringing users a dual "cooling" experience. According to the buyer's feedback, I feel that the mattress "takes away the body heat in bursts, and will never be too hot to sleep". Can the mask fan improve the stuffy feeling when wearing a mask? This year's new mask fan has been improved in terms of shape, motor and weight. Its 3D shape is suitable for all face shapes and masks, creating a "breathing chamber" and three-dimensional support for the mask, so that the makeup on the face will not fall off; The brushless motor design speeds up the air filtration of the mask and makes the air inside the mask fresh; The air duct design allows the front window to speed up the air intake, and the left independent air duct provides air, effectively avoiding virus invasion; Its endurance can reach 6 hours, basically meeting the needs of outdoor travel in a day.
