Description

Technical Field

[0001] The invention belongs to the technical field of hair drying devices, and in particular relates to a hair dryer with an air duct sleeve. Background Art

[0002] A hair dryer generally includes a wind tube and a handle. A heating wire assembly is provided in the wind tube, a motor with a fan blade is provided in the handle, and a plurality of air inlet holes are provided on the circumferential surface of the lower end of the handle. When in use, the motor drives the rotor to drive the fan blade to rotate. When the fan blade rotates, air is sucked in from the air inlet hole under the handle, and the centrifugal airflow formed is blown out from the front end of the wind tube. At the same time, the wires of the hair dryer are inserted from the bottom of the handle, extending upward along the inside of the handle to connect to the control module. When air enters from the air inlet hole under the handle, it is easy to interfere with the wires, which will generate noise when blowing the wires and affect the stability of the connection between the wires and the control module.

[0003] Hair dryers are mainly used to dry hair and style hair. The air volume and wind speed of the hair dryer determine the efficiency of hair drying. At the same time, the air inlet holes are located on the circumference of the lower end of the handle. The air entering each air inlet hole is turbulent, which will reduce the speed at which the air is driven up by the fan blades, thereby affecting the efficiency of hair drying by the hair dryer. Summary of the invention

[0004] The purpose of the present invention is to provide a hair dryer with an air duct sleeve which can accelerate the flow speed of air.

[0005] To this end, the technical solution of the present invention is: a hair dryer with an air duct sleeve, comprising a wind tube and a handle, the wind tube and the handle are fixed as one; a motor with fan blades is arranged in the handle, and a hollow structure is arranged under the handle, a filter screen is arranged on the hollow structure, and a plurality of air inlet holes are arranged on the filter screen; it is characterized in that: an air duct sleeve and a power cord clamp are arranged at the bottom of the handle, the air duct sleeve is a conical structure, the large end is fixedly connected to the power cord clamp, a wire threading hole is arranged at the connection between the air duct sleeve and the power cord clamp, and the power cord clamp is a ring structure with a wire clamping hole in the middle; the air duct sleeve is placed in the hollow structure of the handle, opposite to the position of the air inlet hole.

[0006] Preferably, the upper end surface of the power line card is provided with a plurality of air guide grooves.

[0007] Preferably, a circle of protruding clamping ring is provided in the clamping hole in the middle of the power line clamping plate.

[0008] Preferably, the power line clamp is made of plastic, and the air duct sleeve is made of metal, and the two are inlaid and fixed as one.

[0009] Preferably, the power line clamp is composed of two semi-circular ring structures, and the air duct sleeve is composed of two semi-conical structures.

[0010] Preferably, the air duct sleeve and the power cord clamp are placed in the hollow structure of the handle, and a filter net is placed on the outside.

[0011] The present invention sets a conical air duct sleeve inside the air inlet hole. The air enters from the air inlet hole, and after hitting the air duct sleeve, it moves along the outer wall direction of the air duct sleeve, providing wind flow layer guidance for the air suction blade, thereby arranging the chaotic air into an air layer, and accelerating the flow speed of the air sucked in. At the same time, the port of the power cord is clamped by the middle clamping ring of the power cord clamping plate and fixed in the clamping hole. Then the power cord passes through the threading hole at the bottom of the air duct sleeve and runs along the inner wall of the handle. The air duct sleeve can fix the power cord to prevent the power cord from interfering with the sucked air. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] See the attached drawings. The hair dryer described in this embodiment includes a wind tube 1 and a handle 2, which are fixed as a whole; a motor 3 is arranged inside the handle 2, and a fan blade 8 is installed on the motor shaft; a hollow structure 21 is provided below the handle 2, and a filter 4 is arranged on the hollow structure 21, and a plurality of air inlet holes are arranged on the filter 4. A heating wire assembly and a control module are arranged inside the wind tube, and an air outlet is arranged at the front end of the wind tube. The wind tube is connected with the inside of the handle, and air enters from the air inlet, enters the wind tube along the inside of the handle, and finally blows out from the air outlet of the wind tube.

[0018] The bottom of the handle 2 is provided with an air duct sleeve 5 and a power line card plate 6, the power line card plate 6 is made of plastic, and the air duct sleeve 5 is made of metal, and the two are inlaid and fixed as one; the air duct sleeve 5 is a conical structure, the large end is fixedly connected to the power line card plate 6, and the small end faces the fan blade 8 of the motor 3, and the connection between the air duct sleeve 5 and the power line card plate 6 is provided with a threading hole, the power line card plate 6 is an annular structure, a wire clamping hole 61 is provided in the middle, a circle of protruding clamping rings 62 are provided in the wire clamping hole, and a plurality of air guide grooves 63 are provided on the upper end surface of the power line card plate 6 to facilitate air circulation; the air duct sleeve 5 is placed in the hollow structure 21 of the handle, opposite to the position of the air inlet hole, and the power line card plate is located at the tail of the handle hollow structure and fixed by screws. In order to facilitate the clamping of the wire, the power line card plate is divided into two semi-circular ring structures, and the air duct sleeve is also divided into two semi-conical structures.

[0019] The inner circumferential wall of the handle is provided with an axially distributed air guide groove, and the motor can be limited by the air guide groove after being placed inside the handle; a button is provided on the handle 2, and the button is connected to the control module. The port of the power cord 7 is clamped by the clamp ring in the middle of the power cord clamp plate and fixed in the clamp hole, and then the power cord passes through the threading hole at the bottom of the air duct sleeve and runs along the air guide groove in the handle. The air duct sleeve can fix the power cord.

[0020] When in use, the motor 3 rotates, driving the fan blades, so that air enters from the air inlet of the filter 4. Under the guidance of the outer wall of the air duct sleeve 5, the air flows toward the fan blades in an orderly manner, forming an air flow layer, which speeds up the air flow speed; then the air enters the wind tube through the air inlet channel inside the handle, and is blown out from the air outlet at the front end of the wind tube through the heating wire. If the heating wire installed in the wind tube is powered on and heated, hot air will be blown out from the front end of the wind tube; if the heating wire is not powered on and heated, cold air will be blown out.
