Description

Technical Field

[0001] The utility model relates to the technical field of installation structures of hair dryers, in particular to a wire cap installation structure of a hair dryer. Background Art

[0002] A hair dryer is a mechanical device that accelerates the air flow speed by electric means, generates wind, and increases the air temperature at the same time. It is mainly used for hair drying and shaping, and of course it can also be used for local drying, heating and physical therapy in laboratories, physiotherapy rooms, industrial production, art, etc. In the fast-paced modern work and life, the use of hair dryers is not only necessary, but also increasing. The development and installation of hair dryers directly affect the performance of hair dryers, so the development and installation of hair dryers should be paid special attention to by developers.

[0003] At present, the handle of a general hair dryer is installed with two half shells, which is not only convenient for holding the handle to blow dry, but also allows the connecting wire for electrical connection to pass through the two half shells and be placed at the outer end of the hair dryer. Of course, the bottom end of the connection between the two half shells is installed with a wire cap, so that the connecting wire passes through the wire cap and is placed to make an electrical connection with the external power supply. In this way, the installation of the wire cap not only affects the tightness of the connection between the two half shells, but also directly affects the installation reliability of the connecting wire, and then affects the performance of the hair dryer. In this case, the installation of the wire cap requires a reasonable structural design to face various problems, such as the connection wire cannot be smoothly placed at the outer end of the hair dryer, the wire cap is not tightly connected to the handle, and the wire cap is prone to leakage, etc.

[0004] The Chinese patent authorization announcement number is: CN212754668U, and the authorization announcement date is March 23, 2021.

The shortcoming of this technical solution is that the connection between the wire tail cover body and the handle body is connected by a snap-on structure, and this snap-on structure includes a snap-on part and a snap-on groove, that is, it is necessary to control the snap-on part to rotate relative to the arc guide groove so that the snap-on part is snapped into the snap-on groove. However, the snap-on part and the snap-on groove here may touch the wire tail cover body during the use of the hair dryer, causing the wire tail cover body to rotate in the opposite direction for disassembly. Then, the wire tail cover body may be separated from the limit of the handle body, so that the components in the handle body are damaged by the entry of external objects, which is unsafe.

[0005] In summary, a structure can be provided that can reduce the probability of the wire tail cover body and the handle body being automatically disassembled due to being touched. Utility Model Content

When the wire cap body 3 is rotated, the slot 3 12 is aligned with the slot 2 11, and the slot 3 12 and the slot 2 11 are connected. Then, the insert 10 is controlled to insert the hook 15 installed on the top of the insert 10 into the jack 9 distributed at the bottom end of the wire cap body 3. During the insertion of the hook 15, the insert 10 can also be moved through the slot 3 12, the slot 2 11 and the slot 1 8 in sequence. Here, one end of the slot 1 8 is connected to the slot 2 11. The spring 14 is in the state of being connected with the handle 2, and the other end is closed, that is, at the end of the movement of the insertion strip 10, the end of the insertion strip 10 will be blocked. At this time, the elastic ring 14 can be controlled to move on the outer side of the handle 2 until the insertion strip 10 is pressed. Then, the bottom end of the insertion strip 10 can be squeezed and limited by the elastic ring 14 to prevent the insertion strip 10 from escaping from the limiting work of the handle 2. In this way, the wire cap body 3 is stably connected to the handle 2 with the cooperation of the plug hook 15, the insertion strip 10, the plug hole 9, the slot one 8, the slot two 11, the slot three 12 and the elastic ring 14, so that the wire cap body 3 cannot rotate automatically when hit by foreign objects, affecting the installation of the wire cap. In this way, the purpose of installing a component that can prevent the wire cap body 3 from automatically rotating when touched, thereby losing connection with the handle 2 is achieved. The connection between the hook 15 and the inserting strip 10 is at an obtuse angle α, and the cross-sectional shape of the hook 15 is arc-shaped, that is, there is a distance between the connection between the hook 15 and the inserting strip 10 and the inserting strip 10. Therefore, when the hook 15 is inserted into the insertion hole 9, the inserting strip 10 can naturally be smoothly embedded in the slot three 12, that is, the hook 15 drives the inserting strip 10 to move smoothly.

[0034] The elastic ring 14 here can be made of soft rubber with elastic effect. Due to the elastic effect, the elastic ring 14 squeezes the insert 10 when it is sleeved on the insert 10. At the same time, the rotation of the elastic ring 14 can be manually controlled to allow the elastic ring 14 to move up and down smoothly on the outer surface of the handle 2.
