Compared with the prior art, the beneficial effects of the utility model reside in that: through the cooperation of the heat-resistant structure between the inner wall of the heat-insulating shell and the outer wall of the shell, the heat conduction efficiency between the air outlet nozzle which is hot due to the fact that hot air is blown out for a long time and the heat-insulating shell is greatly inhibited, so that the heat-insulating shell keeps a proper temperature, and the scalding risk when the heat-insulating shell is in accidental contact with a human body is well controlled.
Description
Technical Field
The utility model relates to an hairdryer technical field, specific is a wind nozzle is prevented scalding by air outlet for hairdryer.
Background
The hair drier is mainly used for drying and shaping hair, but also can be used for local drying, heating and physical therapy in laboratories, physical therapy rooms, industrial production, art designing and other aspects. The electric hair drier works by driving a rotor to drive a fan blade to rotate by a motor, so that an air duct which enables air to be sucked from an air inlet and blown out from an air outlet is formed; and a heating bracket with a heating wire is arranged at one end of the air duct, which is positioned at the air outlet, and hot air with higher temperature is blown out if the heating wire is electrified to be heated.
In the process of using the hairdryer, in view of the air outlet blows off hot-blast for a long time, the air outlet can be scalded gradually, has the scald risk when the air outlet of high temperature accident contacts the human body. And there is not yet simple effectual solution to the scald risk that the air outlet hair perms and leads to among the prior art.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a weak point to prior art, provide an air outlet prevents scalding tuyere for hairdryer, its technical scheme as follows.
The anti-scald air nozzle for the air outlet of the electric hair drier comprises a shell with a thin-wall structure, wherein the shell is provided with a connecting port which is coaxially connected with the air outlet of the electric hair drier, and the shell is also provided with an air outlet nozzle which extends out along the axis of the connecting port so as to supply air to the outside; the shell is provided with a heat insulation shell sleeved on the outer wall at one end where the air outlet nozzle is located, and a heat resistance structure is constructed between the inner wall of the heat insulation shell and the outer wall of the shell.
Compared with the prior art, the beneficial effects of the utility model reside in that:
through the cooperation of the heat-resistant structure between the inner wall of the heat-insulating shell and the outer wall of the shell, the heat conduction efficiency between the air outlet nozzle which is hot due to the fact that hot air is blown out for a long time and the heat-insulating shell is greatly inhibited, so that the heat-insulating shell keeps a proper temperature, and the scalding risk when the heat-insulating shell is in accidental contact with a human body is well controlled.
The present invention will be further described with reference to the drawings and the detailed description.

Detailed Description
As shown in fig. 1 to fig. 3, the anti-scald air nozzle for the air outlet of the hair dryer comprises a shell 1 with a thin-wall structure, wherein the shell 1 is provided with a connecting port 11 coaxially connected with the air outlet of the hair dryer, and the shell 1 is further provided with an air outlet 12 extending along the axis of the connecting port 11 to supply air to the outside; the shell 1 is provided with a heat insulation shell 2 sleeved on the outer wall at one end where the air outlet 12 is located, and a heat resistance structure 3 is constructed between the inner wall of the heat insulation shell 2 and the outer wall of the shell 1.
In the above embodiment, the inner wall of the heat insulating casing 2 and the outer wall of the housing 1 are engaged with each other through the heat blocking structure 3, so that the heat conduction efficiency between the air outlet 12, which is hot due to the long-time blowing of hot air, and the heat insulating casing 2 is greatly suppressed, the heat insulating casing 2 is kept at an appropriate temperature, and the risk of scalding when accidentally contacting the human body is well controlled.
Preferably, the heat-resistant structure 3 is a silicone ring tightly fitted between the inner wall of the heat-insulating casing 2 and the outer wall of the housing 1. The silica gel ring has ideal thermal resistance and good elasticity, can meet the design effect of the thermal-resistant structure 3, and can ensure that the thermal-insulated shell 2 and the shell 1 are combined more stably without worry of accidental falling.
Further, the outer wall of the shell 1 is formed with a groove 13 for embedding a silica gel ring, so as to enhance the position stability of the silica gel ring.
As a modification of the above embodiment, a convex abutting portion 14 is formed on the outer wall of the housing 1, and one end of the heat insulating housing 2 facing the connection port 11 abuts against the abutting portion 14. The abutting portion 14 realizes a positioning reference when the heat insulating housing 2 is assembled, and is easier to assemble.
As a modification of the above embodiment, the outer wall of the housing 1 is formed with a concave socket 15, and the inner wall of the heat insulating casing 2 is formed with a fitting 21 which can be inserted into the socket 15. Through the cooperation of joint 21 and socket 15 can realize preventing slow-witted location when the assembly, also can avoid thermal-insulated shell 2 circumferential displacement.
As a modification of the above embodiment, the air outlet 12 is constructed in a stepped structure receding toward the axis, and the outer end of the heat insulating casing 2 is in clearance fit with the air outlet 12 through the stepped structure of the air outlet 12. The outer end of the heat insulation shell 2 is the position which is most easily contacted with a human body, the outer end of the heat insulation shell 2 is in clearance fit with the air outlet nozzle 12, and the air gap is actually used as reliable heat conduction isolation to ensure that the outer end of the heat insulation shell 2 cannot be scalded.
For those skilled in the art, the protection scope of the present invention is not limited to the details of the above-described exemplary embodiments, and all the embodiments with variations within the scope and meaning equivalent to the elements of the present invention should be included in the present invention without departing from the spirit or essential characteristics of the present invention.
