Description

Technical Field

[0001] The invention relates to the technical field of hair dryers, in particular to a handheld hair dryer. Background Art

[0002] After washing our hair, we need to blow dry the wet hair in time, especially in winter, when the hair dries very slowly. A hair dryer is a tool commonly used by people to dry hair. We all have an experience in using a hair dryer. If we directly blow hot air at the hair with a hair dryer without combing the hair while blowing the hot air, the hair will appear very messy after drying without a hairstyle, and dry hair is also difficult to take care of. In order to solve the above problems, a hair dryer that blows out hot air and cold air at the same time is needed. For this purpose, we design a handheld hair dryer.

[0003] At present, most of the existing handheld hair dryers have the following deficiencies: when using the handheld hair dryer to dry hair, the hair dryer has only one blowing channel and cannot blow out hot air and cold air at the same time. Since hair care products such as conditioners cannot be blown onto the hair through hot air, it is inconvenient to care for the hair. At the same time, the hair dryer generates a lot of noise when used, which affects people's hair care operations. In summary, most of the existing handheld hair dryers cannot meet actual needs well. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the present invention provides a handheld hair dryer, which is mainly used to solve the problem that when using a handheld hair dryer to dry hair, since the hair dryer has only one blowing channel, it is impossible to blow out hot air and cold air at the same time, and hair care products such as conditioner cannot be blown onto the hair through the hot air, making hair care inconvenient and affecting people's hair care work efficiency.

[0006] (II) Technical solution

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0009] Further: the circumferential outer wall of the main shell is clamped with a side shell.

[0010] On the basis of the above-mentioned solution: the upper surface of the hollow frame is fixedly connected to a fixing frame, the upper surface of the fixing frame is fixedly connected to a processor, and the processor is electrically connected to the motor and the heater.

[0011] As a further solution of the present invention: a protective cover is clamped on the circumferential outer wall of the side shell.

[0012] Further: the circumferential outer walls of the main shell and the arc-shaped shell are clamped with a connecting tube.

[0013] On the basis of the above scheme: a temperature sensor is arranged on one side of the upper surface of the mica shell, the heater is electrically connected to the temperature sensor, and a temperature protection switch is electrically connected to the upper surface of the temperature sensor.

[0014] As a further solution of the present invention: a touch switch is clamped on the circumferential outer wall of the main housing and the arc-shaped housing, and a button is clamped on one side outer wall of the touch switch.

[0015] Further: the circumferential outer walls of the main shell and the arc-shaped shell are sleeved with a hollow air inlet cylinder, and the circumferential outer walls of the main shell and the arc-shaped shell are provided with multiple air inlets, the air inlets correspond to the positions of the hollow air inlet cylinder, the first stainless steel filter, the gauze and the second stainless steel filter, and the top end of the hollow air inlet cylinder is clamped with the bottom end of the connecting cylinder.

[0016] On the basis of the above-mentioned solution: a wire fixing plug is clamped at the bottom of the main shell and the arc-shaped shell, and a protective plug is movably connected between the main shell and the arc-shaped shell.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present invention provides a handheld hair dryer having the following beneficial effects:

[0019] 1. The present invention, by setting the circumferential inner wall of the arc-surface air guide tube as a wall-attached curved surface, will cause the air to produce a Coanda effect when it is discharged, generate a negative pressure area, increase passive airflow, and the airflow will quickly penetrate the hollow area of ​​the mica cover, and at the same time can take away hair care products such as conditioners attached therein. Since this part of the airflow is natural wind and has not been heated, it can well prevent hair care products such as conditioners from being decomposed by high temperatures, thereby truly achieving the effect of drying hair while using passive airflow to complete hair care. Since the present invention utilizes the Coanda effect, the passive airflow is increased, thereby reducing the pressure on the motor intake, and can ensure that the speed of the cold air drawn in reaches 4 meters per second, which is significantly higher than the air volume and wind speed of similar products, and at the same time extends the life of the motor.

[0020] 2. The present invention can divide the annular air outlet between the curved air guide tube and the mica cover into six sections of fan-shaped air outlet surfaces by setting six tapered ribs. The structure of the tapered ribs is that the thin end faces inward and the thick end faces outward, so that the annular airflow can be divided into six areas to avoid airflow interference between adjacent fan-shaped surfaces and reduce noise. At the same time, the setting of 1% to 5% porosity micropores on the mica cover uses the micropore noise reduction principle to reduce noise when the high-speed airflow coming out of the handle directly impacts the mica cover on the outer circle of the heating mechanism. The microporous filter uses the microporous noise reduction principle to reduce the noise when the motor is running. The first stainless steel filter, gauze and the second stainless steel filter are combined to reduce the noise of the air inlet according to the microporous noise reduction principle.

[0021] 3. The present invention, through the provision of a temperature sensor and a temperature protection switch, can enable the temperature sensor to upload a signal to the temperature protection switch when the temperature of the heater rises after long-term use, thereby stopping the use of the heater to prevent the hair from drying out due to excessive temperature, thereby ensuring the quality of the hair.

[0022] 4. The present invention provides a fixing plug and a protective plug. The fixing plug is used to fix the power cord of the hair dryer. Meanwhile, the protective plug protects the bending part of the power cord to prevent the power cord from being damaged when the hair dryer is used, thereby ensuring the service life of the hair dryer.
