Description

Technical Field

[0001] The present invention relates to the technical field related to body dryers, and in particular to a waterproof and dustproof 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 existing dryers, the air outlet is placed upward to blow towards the human body, so hair and liquid can easily enter the air outlet. Especially in a humid environment, there is often a lot of water vapor, which affects the normal operation of the dryer and is not conducive to extending its service life. Summary of the invention

[0032] In the first embodiment, the raised design of the boss 31 is conducive to reducing the entry of water flow into the air outlet 33. At the same time, the inclined surface 36 makes it easier for the air outlet areas 3 at both ends of the dryer to blow toward the front and back parts of the human body, which is conducive to improving the drying efficiency of the human body, while further preventing the entry of water and preventing the entry of hair during operation. When in use, the operator rotates the cover body 34 so that the plurality of through holes 35 are connected to the air outlet 33 in a one-to-one correspondence, so that the air flow is blown toward the human body to dry the body.

[0033] In the second embodiment, during operation, the operator connects the power supply through the power cord 5, and then controls the operation of the dryer through the touch panel 4; under the action of the motor 41, the air flow enters the air duct 7 from the air inlet grille 2, passes through the filter 40 and then flows through the main control board 42, and finally is heated by the heater 9 and then blows toward the human body from the air outlet 33; in the above process, the main control board 42 is located between the heater 9 and the motor 41, which is beneficial for natural cold air to dissipate heat and remove water vapor from the main control board 42, which is beneficial for the heat dissipation of the main control board 42, thereby helping to extend the service life of the main control board 42. The air duct 7 is threadedly connected to the mounting column 43 after the bolt 11 cooperates with the threaded hole 12. During the operation, the motor 41 will generate vibration and transmit the vibration wave to the air duct 7, which can easily cause the bolt 11 to loosen, thereby causing noise. Therefore, after the bolt 11 is matched with the threaded hole 12, the operator rotates the drive ring 15 so that the drive ring 15 produces a linear motion on the mounting column 43 under the action of the mutual cooperation between the internal thread section and the external thread section on the mounting column 43. During this process, the magnetic strip 17 gradually approaches the bolt 11 until it is attracted to the bolt 11. Under the action of magnetic attraction, the matching strength between the bolt 11 and the threaded hole 12 and the matching strength between the drive ring 15 and the external thread section on the mounting column 43 are increased, so that the bolt 11 is locked on the original basis to prevent the bolt 11 from loosening and generating a lot of noise.
