Description

Technical Field

[0001] The present invention relates to the technical field related to body dryers, and in particular to a body dryer. Background Art

[0002] People need to dry their bodies after bathing. The traditional way of drying the body with a towel has defects in terms of dryness, hygiene, convenience, etc. For example, in public shower places, the shower room and the dressing room are often connected together, and the mist in the shower room will drift into the dressing room, resulting in a high humidity in the air in the dressing room. At this time, the effect of wiping the body with a towel, especially a semi-dry towel used in the shower, is very poor. At this time, not only does it feel bad to wear clothes, but it is also easy to catch a cold when going out. Some customers will use a hair dryer to blow all over their body, which is time-consuming and easy to catch a cold, especially for people with long hair. It is time-consuming and troublesome, and the management regulations of those public shower places often do not allow the use of a hair dryer to blow the body when the equipment is limited. In addition, from the perspective of hygiene, if you only bring a towel, it is not hygienic to use it to dry your body from head to toe. And if you use a towel to dry your body in the dressing room, the water from the dry body will be squeezed on the ground, resulting in an increase in management costs and difficulties. For example, using a hotel bath towel or towel to dry your body in a hotel also has certain hygiene risks. In terms of household use, people still have the problem of resource consumption such as placement, washing and drying of these toiletries when using towels or bath towels. In terms of medical care and elderly care, we also need to consider the problems of patients or elderly people's inconvenience in movement, weak constitution, poor self-care ability, etc. Therefore, people have designed a body dryer for drying people's bodies, which can solve the above defects of traditional towel drying.

[0003] In the prior art, dryers still have the following deficiencies: since dryers are usually used in environments with high humidity and temperature, the main control board in the dryer usually cannot dissipate heat effectively, and its surface is usually covered with a certain degree of water vapor, which is not conducive to extending its service life; when the dryer is working, it makes a lot of noise, which is not conducive to human health and environmental protection; the dryer has a single blowing position, resulting in insufficient air volume, and there is also a problem of uneven wind speed, which is not conducive to achieving a quick drying effect, etc. Summary of the invention
