Description

Technical Field

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

[0002] After people take a bath, they need to dry their bodies. 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 changing room are often connected together, and the mist in the shower room will drift into the changing room, resulting in high humidity of the air in the changing room itself. At this time, relying solely on a towel, especially a semi-dry towel used after showering, to wipe the body has a very poor effect. At this time, not only does it feel bad to put on clothes, but it is also easy to catch a cold when going out. Some customers will use a hair dryer to blow their whole body up and down, which is time-consuming and also easy to catch a cold. Especially for people with long hair, it is very time-consuming and troublesome. Moreover, under the condition of limited equipment, the management regulations of those public shower places often do not allow using a hair dryer to blow the body. In addition, from the perspective of hygiene, if only one towel is brought, it is not hygienic to use it to dry the body from head to toe. And when using a towel to dry the body in the changing room, the water for drying the body will be squeezed on the ground, resulting in an increase in management costs and difficulties. Another example is using the hotel's bath towel or towel to dry the body in the hotel, which also has certain hygiene risk problems. In terms of household use, there are also problems of consumption of resources such as the placement, cleaning, and drying of these bath products when people use towels or bath towels. In terms of medical care and elderly care, problems such as the inconvenience of movement, weakness of physical constitution, and poor self-care ability of patients or the elderly also need to be considered. Therefore, people have designed a body dryer to dry people's bodies, which can solve the above-mentioned defects of drying the body with a towel traditionally.

[0003] In the prior art, since the body dryer needs to suck air flow through a motor, the motor is usually installed in the pipeline, which easily leads to low heat dissipation efficiency of the motor and affects the service life of the motor; in addition, since the body dryer is usually used in an environment with high humidity, under the suction of the motor, a negative pressure is generated inside the pipeline, and external water vapor is easily brought into the pipeline, thereby causing certain damage to the electronic devices inside the pipeline; and the air outlet range is limited. Especially for users with a larger body size, it is impossible to sweep the air over a large area of the body. Summary of the Invention

[0004] The present invention is to overcome the deficiency of low heat dissipation efficiency of the motor in the pipeline in the prior art, and provides an air duct of a body dryer that is beneficial to improving the heat dissipation efficiency of the motor.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: An air duct of a body dryer, which includes: An air duct body, one end of the air duct body is provided with an air inlet, and the other end of the air duct body is provided with an air outlet; A plate filter, detachably installed in the air inlet of the air duct body; An air direction adjustment component, detachably connected to the air outlet of the air duct body; A motor, a main control board and a heater, all detachably installed in the air duct body and distributed in sequence from the air inlet to the air outlet of the air duct body; Several heat dissipation fins, vertically and fixedly connected to the outside of the air duct body and corresponding to the motor. The motor is placed inside the air duct body, so that natural wind, driven by the motor, enters from the air inlet, passes through the filtration of the plate filter and then enters the air duct body, flows through the main control board and is heated by the heater, and finally blows towards the human body through the air outlet, playing a role in drying the human body; the main control board is located between the heater and the motor, which is beneficial to the natural cold air to dissipate heat from the main control board and remove water vapor, facilitating the heat dissipation of the main control board, and thus conducive to extending the service life of the main control board; the air direction adjustment component is used to adjust the air outlet direction to expand the air sweeping range, so as to expand the range of applicable people with different body types and improve the practicability; the heat generated by the motor itself is dissipated to the outside through the heat dissipation fins, achieving the purpose of facilitating the improvement of the motor heat dissipation efficiency.

When in use, the air duct body is horizontally placed in the shell, so that the air outlet faces upwards towards the human body; after use, the water vapor in the external air is likely to adhere to the plate filter. Therefore, through the oblique arrangement of the plate filter, it is beneficial for the water vapor adhering to the plate filter to gather and then fall off, reducing the risk of its infiltration into the air duct body, and thus conducive to improving the moisture-proof ability.

Further, arranging the flow guide plate in the air inlet is beneficial for the water vapor adhering to the plate filter to gather and fall off, and then be drained out of the air duct body through the flow guide plate from the air inlet, further reducing the risk of its infiltration into the air duct body, and thus conducive to improving the moisture-proof ability.

[0008] Preferably, the other end of the air duct body is provided with an air outlet pipe. The air outlet pipe is in an L shape, and the bent part of the air outlet pipe is in an arc structure. One end of the air outlet pipe is uniformly transitioned to the other end through the arc structure. One end of the air outlet pipe is sleeved on the outer side wall of the air duct body and is hermetically snap-connected to the air duct body. The center of the other end of the air outlet pipe is recessed into the air outlet pipe to form a wind guiding groove. The bottom shape of the wind guiding groove is hemispherical, and the opening end of the wind guiding groove forms a flared opening that opens outward. There are a plurality of air outlet openings, which are located at the other end of the air outlet pipe. The plurality of air outlet openings are evenly distributed along the circumferential direction around the wind guiding groove on the end surface of the opening end of the wind guiding groove. The wind direction adjusting assembly is detachably installed on the other end of the air outlet pipe. The design of the arc structure at the bent part of the air outlet pipe is beneficial to reducing the wind resistance, thereby facilitating reducing the noise during air supply and reducing the energy loss; the structural design of the wind guiding groove is beneficial to reducing the wind resistance, thereby facilitating noise reduction; at the same time, the bottom shape of the wind guiding groove is hemispherical, and the structure design of the flared opening is beneficial to reducing the water from splashing into the air duct body through the air outlet openings, having a good waterproof effect; the plurality of air outlet openings are evenly distributed along the circumferential direction on the end surface of the opening end of the wind guiding groove, so that the hot air can be evenly blown to the human body, improving the human comfort; a wire outlet hole is provided on the side wall of the wind guiding groove and a sealing body (not shown in the figure) for sealing the wire body, facilitating the wire outlet connection of the driving mechanism.

A driving mechanism is provided in the wind guiding groove. The plurality of wind guiding blades are synchronously rotatably connected to the fixing ring under the drive of the driving mechanism. The gap facilitates the driving mechanism to drive the wind guiding blades to rotate synchronously, so that the wind at the air outlet openings can be swept horizontally, so as to expand the sweeping range, thereby expanding the applicable population range of different body types and improving the practicability; installing the driving mechanism in the wind guiding groove is beneficial to saving space on the one hand, and on the other hand, facilitating maintenance and heat dissipation.

[0010] Preferably, the outer side wall of the wind guiding groove is located inside the air outlet pipe, and a heat insulation layer is covered on the inner side wall of the wind guiding groove. The heat insulation layer is fixedly connected to the wind guiding groove. The heat insulation layer is beneficial to preventing the heat generated by the heater from being conducted to the driving mechanism through the side wall of the wind guiding groove, thereby facilitating extending its service life.

[0011] Preferably, the driving mechanism includes a motor base, a reduction motor and a push rod. The motor base is fixedly connected to the bottom of the air guide groove.
