As shown in fig. 1, the application discloses an intelligent clothes-airing device with a drying function, which comprises a main body part 1 and a clothes rod part 2 arranged below the main body part 1, wherein the main body part 1 is connected with the clothes rod part 2 through a lifting mechanism 3. The lifting mechanism 3 is provided at both end positions of the main body 1 to leave a central region of the main body 1 empty, as a drying region of a drying assembly 4 described below. In the present application, the clothes pole 2 and the lifting mechanism 3 are common technical means in the art, and detailed description thereof is omitted.
In the present application, a drying assembly 4 for supplying hot air to the clothes-horse 2 is provided in the main body 1, so that the clothes on the clothes-horse 2 are dried by the drying assembly 4. The drying assembly 4 will be described in detail.
In the present application, the drying assembly 4 includes a heating assembly and a duct for circulating the heated air flow, and the heating assembly is used for heating the air, so that the heating assembly is disposed at an air inlet end of the duct, that is, a front end of the duct, and the air heated by the heating assembly enters the duct and flows in the duct.
In the present application, the pipe includes a pipe body 401 and a muffler pipe 402 provided outside the pipe body 401, and the muffler pipe 402 is provided coaxially with the pipe body 401.
Specifically, as shown in fig. 3, the muffler pipe 402 includes an inner pipe 402a attached to the outside of the pipe body 401, and a reflection chamber 402b provided outside the inner pipe 402 a. The inner tube 402a is disposed around the outside of the pipe body 401 such that the inner tube 402a and the pipe body 401 are coaxial, and at the same time, when the inner tube 402a is disposed, both end portions of the inner tube 402a and both end portions of the pipe body 401 are fastened together with screws, and therefore, both ends of the inner tube 402a are respectively provided with shoulders 402e for connection with the pipe body 401, and a ring of sealing rings 402f is provided between the shoulders 402e and the pipe body 401 to seal the inner region of the inner tube 402 a. Through the connection between the shoulder 402e and the pipe body 401, the transmission of sound waves at the connection position can be effectively restrained, so that the noise is further reduced. In addition, the length of the inner tube 402a is equal to the length of the pipe body 401, so as to ensure that the inner tube 402a can coat the pipe body 401 in all directions.
In the present application, the inner tube 402a is separated from the reflective cavity 402b by the partition 402c, and the partition 402c is covered with the through-holes 402d communicating the inner tube 402a and the reflective cavity 402b. In the inner tube 402a, there is provided a spring net 403 parallel to the axis of the inner tube 402a, both ends of the spring net 403 are fixed to both ends of the inner tube 402a, respectively, and both side portions of the spring net 403 are butted so that the spring net 403 constitutes a cylindrical body, and the spring net 403 is disposed coaxially with the tube body 401.

When the sound wave is transmitted into the reflective cavity 402b through the through hole 402d, multiple reflections are performed on the inner wall of the reflective cavity 402b, and a certain amount of energy is lost after each reflection, so that the sound wave consumed by the spring net 403 can be completely consumed after entering the reflective cavity 402b, and noise is completely eliminated.

By this arrangement, the frequency range in which the reflection cavity 402b suppresses noise can be enlarged. In the present application, the resonant rod 406 is a hollow rod body, and the resonant rod 406 is a metal member, and in the same reflecting cavity unit 404, the length of the resonant rod 406 increases gradually, that is, increases along the flow direction of the air flow, the root of the resonant rod 406 is connected to the partition 402c, and the rods of the resonant rod 406 are distributed along the radial direction of the pipe body 401. When sound waves are transmitted into the reflective cavity unit 404, the sound wave energy of a plurality of frequency ranges is absorbed by the plurality of such resonant rods 406 cooperating with the inner walls of the reflective cavity unit 404. For example, in one embodiment of the present application, three resonant rods 406 of different lengths are provided in the same reflective cavity unit 404.
In the present application, as shown in fig. 4, the heating assembly includes a thermal resistor 407 and a heating tube 408, an air inlet pipe of the heating tube 408 is connected with a fan, and an air outlet end of the heating tube 408 is connected with a pipe body 401.
