Description

A handleless hair dryer

The invention relates to a hair dryer, in particular to a hair dryer without a handle. Background technique

Conventional hair dryers are composed of a casing, a handle, an electric motor, a fan blade, an electric heating element, a switch, a power supply line, etc., the motor is housed in the casing, and the vane is mounted on the shaft end of the motor. When the motor rotates, air is taken in by the air inlet, and the air is blown out by the air outlet. The electric heating element of the hair dryer is wound by a heating wire and installed at the air outlet of the hair dryer. The wind discharged from the motor is heated by the heating wire at the air outlet, and is sent to the hot air. The traditional hair dryer has a "7" shape and must have a handle for easy handling. The setting of the handle is not only a traditional feature of the product structure, but also because the hair dryer generates heat when the hair dryer is working, especially when the hot air is working, so that the person cannot directly operate the casing. The presence of the handle on the one hand causes an increase in cost, and on the other hand, the hair dryer is inconvenient to carry due to the "7"-shaped structure.

The electric motor and electric heating element in the hair dryer generate electromagnetic radiation during operation, especially when opening and closing. The current hair dryer does not consider the damage of the electromagnetic radiation to the human body. Summary of the invention

The problem to be solved by the present invention is to provide a hair dryer having a simple shape, no handle, low cost, and a portable belt.

In order to achieve the above object, the present invention devises a handleless hair dryer, including a casing and a switch And the power cable, the outer casing is composed of an air outlet cylinder at the front end and a rear casing connected to the air outlet cylinder. The motor, the blades and the electric heating element are disposed in the rear casing, and a plurality of convexities are distributed on the air outlet cylinder. Starting from the block, a card slot is arranged at the front end of the air outlet, and a plurality of card jacks are distributed on the card slot.

As an improvement to the above solution: the inner wall of the air outlet cylinder and the rear casing is provided with a layer of radiation preventing material, and the radiation preventing material layer is composed of flaky graphite powder, acetylene carbon powder, carbonyl iron powder, ferrite It is a mixture of body powder diffusing agent, cement, film forming agent, ammonia water and pure water.

As a further improvement to the above solution, the protruding block is an elongated protrusion which is disposed at the end of the air outlet cylinder near the casing of the rear cover, and the protrusion is integrated with the air outlet casing forming.

As a further improvement to the above solution: the air outlet is connected with a releasable nutrient tuyere or with a brush tuyere, and a card slot is provided on the inner wall of the releasable nutrient tuyere or with a tulle tuyere The ribs and blocks corresponding to the card jack bits.

The releasable nutrient tuyere according to the present invention comprises a casing, a positioning frame and a container for accommodating nutrients, wherein the positioning frame is disposed in the casing, so that the casing forms three air outlets, and the positioning at the middle air outlet The rack is provided with a container for accommodating nutrients. The brushed tuyere includes a cylindrical casing, and a bristle block is disposed at an air outlet of the casing.

In addition, the air outlet cylinder of the present invention has a cylindrical shape, and the length of the air outlet cylinder is at least twice the length of the rear casing, and the diameter of the air outlet cylinder is 5 to 16 cm.

The handleless hair dryer of the present invention has the following advantages:

1. The main body of the hair dryer of the present invention is composed of an air outlet cylinder and a rear casing. The air outlet cylinder is of a size that can be held by one hand, and a convex block is arranged at the position of the air outlet cylinder, and the motor and the fan blade are arranged. The electric heating element is disposed in the rear casing. When the air cylinder is held by the hand, the heat generated by the electric heating element is not affected by the heat and the hand.

2. It is convenient to increase the difference by setting the card slot and card jack at the air outlet. A wind nozzle, such as a nutrient-free mouthpiece or a bristles, to achieve different functions;

3. A layer of anti-radiation material is arranged on the inner wall of the air outlet cylinder and the rear casing, which can effectively reduce the influence of invisible electromagnetic radiation on the human body when using the hair dryer. BRIEF DESCRIPTION OF THE DRAWINGS:
