Description

Wireless bladeless baby hair drier

Technical Field

The utility model relates to a hair-dryer technical field, concretely relates to wireless bladeless baby's hair-dryer.

Background

Currently, there are mainly 2 types of infant hair dryers on the market.

1. Traditional wired hair-dryer adopts 220V alternating current power supply, receives the restriction of easy electric wire and power during the use, keeps away from the socket or when electric wire length is not enough when the baby, needs to increase the electrified line row of inserting and just can use, when no power, then the condition that can't use appears. Meanwhile, the traditional wired hair dryer is loud in noise and easy to frighten infants.

2. The wireless hair dryer adopts a dry battery or a rechargeable battery as a power supply, and solves the problem of limited use space. But when several parameters such as endurance, heating, dead weight and the like are comprehensively considered, the product advantages cannot be brought into full play. For example, 6 14500 batteries are adopted as a power supply for a certain product, the service time of the product is not more than 20 minutes in normal use, and when the electric quantity of the batteries is lower than a set value, only the motor rotates to blow out cold air, so that the product is uncomfortable for infants and sick when the infants are seriously cold. Meanwhile, the existing wireless hair dryer still has large noise when in high gear, and is easy to frighten infants. In addition, the existing wireless hair drier has over concentrated blowing, so that the blown air is not soft, and the comfort of infants is reduced.

SUMMERY OF THE UTILITY MODEL

The utility model discloses to prior art defect and not enough, provide a wireless no leaf baby's hair-dryer, can optimize the hair-dryer performance, noise abatement, it is soft to blow, improves the comfort that baby used.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a wireless no leaf baby's hair-dryer, which comprises a housin, a power supply, a motor, fan and heat-generating body, at the first wind channel of casing internal connection, first wind channel internal connection mount pad, the motor is connected to the mount pad, connect the fan on the motor, the one end in first wind channel is towards the air inlet, the second wind channel is connected to the other end, the heat-generating body is connected through the mount pad to second wind channel inside, the one end in third wind channel is connected with the second wind channel, the other end is towards the air outlet, the protection casing is connected to the air outlet, motor and heat-generating body and power electric connection.

Further, the power supply is a dry battery or a rechargeable battery, and the rechargeable battery is provided with a corresponding charging port.

Furthermore, the first air duct, the second air duct and the third air duct are smooth in interior and smooth in mutual connection, and the axes of the first air duct and the third air duct are not collinear to form a certain included angle; the first air duct is in a conical cylinder shape, and the large end faces the air inlet; the second air duct comprises a bent pipe section; the third air duct comprises a straight pipe section and a cone section, one end of the straight pipe section is connected with the cone section, the other end of the straight pipe section is connected with the second air duct, the section of the straight pipe section is circular or oval, the section area of the straight pipe section is smaller than that of the large end of the second air duct, and the large end of the cone opening of the cone section faces the air outlet.

Furthermore, a group of air diffusing pieces are arranged on the protective cover, the cross section of each air diffusing piece is triangular, and the included angle of the tops of the triangles is 15-25 degrees.

Furthermore, a hollow body is formed between the first air duct, the second air duct and the third air duct and the shell, fire-retardant soundproof cotton is arranged in the hollow body, and the fire-retardant soundproof cotton can be compactly compressed in the hollow body and also can be fixed in the hollow body by gluing.

The utility model discloses following beneficial effect has:

1. the problem of limited use space can be solved for the power is dry battery or rechargeable battery.

2. The sucked air enters the second air channel from the first air channel and is heated by the heating body in the second air channel, the hot air passes through the third air channel with the reduced cross section, the flow speed of the hot air is accelerated, the heat energy exchange loss is reduced due to the small cross section, and the fire-retardant soundproof cotton also has a certain heat preservation and heat insulation effect. As mentioned above, the hair dryer can dry the hair or the buttocks of the baby quickly under the same power, and the performance of the hair dryer is optimized.

3. The propagation of noise in the wind channel can be reduced to back-fire sound insulation cotton, noise reduction.

4. After concentrated wind of the straight pipe section of the third pipeline blows into the cone section, wind flow is dispersed for the first time, then the wind flow is guided by the wind dispersing sheets with the triangular sections, the wind flow is dispersed for the second time, and finally the wind blowing to the hair or the buttocks of the baby is softer and more comfortable.
