The technical scheme of the utility model is further described below by the specific embodiments with reference to the accompanying drawings.
As shown in fig. 1, the present utility model provides an intelligent blower with a pressure sensor, comprising: an air outlet 1, a shell (comprising a front shell 2 and a rear shell 10), a fan 9, a heating device, a motor 11, a control panel 7, an air inlet 13 and a handle 14. The heating device comprises an electric heating wire 5, an electric heating wire winding bracket 6 and an electric heating wire fixing piece 8, wherein the electric heating wire 5 is wound on the electric heating wire winding bracket 6, and the electric heating wire fixing piece 8 fixes the electric heating wire winding bracket 6 in the air duct.
Further, the handle 14 of the intelligent hair dryer with the pressure sensor is provided with the pressure sensor 4, and the pressure sensor 4 transmits detected pressure information to the control panel 7. After the power is turned on, when the intelligent blower is not used, the pressure sensor 4 detects that the pressure value is zero, and the control board 7 does not receive the pressure information transmitted by the pressure sensor 4, so that the intelligent blower is judged to be in a standby state, and the heating wire 5 and the fan 9 are kept in a non-started state. When the blower is ready for use, the user holds up the blower with his hand while grasping the handle 14 of the intelligent blower, also presses against the pressure sensor 4. The pressure sensor 4 detects the presence of pressure and transmits this pressure information to the control board 7. After receiving the pressure information, the control board 7 judges that the blower needs to be in an operating state, and then starts the heating wire 5 and the motor 11, and the motor 11 drives the fan 9 to rotate.
Further, the handle 14 is provided with a distance sensor 3 for detecting the distance from the tuyere to the hair surface.
Further, in order to ensure that the distance sensor detects the distance between the air outlet of the hair dryer and the hair surface, the vertical distance from the detection point of the distance sensor to the air outlet in the direction of the air outlet should be as small as possible. The utility model designs the vertical distance from the center point of the sensor to the extension line of the center point of the air outlet along the direction of the air outlet to be less than 10 cm. The diameter of the air outlet of the blower is 4-5 cm, the diameter of the head of a person is usually 17-20 cm, and the vertical distance from the center point of the sensor to the extension line of the center point of the air outlet along the direction of the air outlet is designed to be 8 cm in the embodiment, so that the detection point of the distance sensor basically falls on the surface of the hair.
Further, the intelligent hair dryer with the pressure sensor is provided with a temperature sensor 12 for detecting the temperature of ambient air. When the intelligent hair dryer is started to start an operation mode, the distance sensor 3 and the temperature sensor 12 are started simultaneously while the heating wire 5 and the motor 11 are started. The distance sensor 3 detects the distance D from the air outlet 1 of the blower to the hair surface 1 And the detected distance D 1 To the control board 7; at the same time, the ambient temperature sensor 12 detects the ambient temperature T at the smart dryer handle Environment (environment) And to detect the ambient temperature T Environment (environment) To the control board 7. The control board 7 receives the distance D 1 And T Environment (environment) The formula is introduced:
P heating rack = （D 1 × P x + P Safe power ）+（25 - T Environment (environment) ）× P Compensation ；
Wherein P is x Is P Heating rack Distance D from 1 Depending on the maximum power of the blower, it is preferred in this embodiment60W/cm;
P safe power Is the power, P, of the blower when the air outlet contacts the hair surface Safe power In the range of more than 50W and less than 500W, preferably 200W in the present embodiment;
T environment (environment) Is the temperature of the ambient air at which the blower is positioned and detected by the temperature sensor, T Environment (environment) The range of (2) is greater than-5 ℃ and less than 40 ℃, and the environment temperature is assumed to be 20 ℃ in the embodiment;
P compensation Is aimed at compensating the power of the blower due to the influence of the temperature of the ambient air, P Compensation In the range of more than 3W and less than 100W, and in this embodiment, it is preferably 20W/. Degree.C.
When the distance between the air outlet 1 of the intelligent blower with the pressure sensor and the hair surface is 10cm, the power P of the heating wire 5 of the blower Heating rack = (10×40+200) + (25-20) ×20=700W), the temperature of the blower's wind blowing onto the hair surface is 58 ℃ (assuming this is the optimum temperature of the blower blowing onto the hair surface required by the user);
when the distance between the air outlet 1 of the intelligent blower with the pressure sensor and the hair surface is 5cm, the power P of the heating wire 5 of the blower Heating rack = (5×40+200) + (25-20) ×20=500W, and the temperature of the blower blowing on the hair surface is 58 ℃;
when the distance between the air outlet 1 of the intelligent blower with the pressure sensor and the hair surface is 0, the power P of the heating wire 5 of the blower Heating rack The power of the heating wire 5 is the lowest at the moment of the= (0×40+200) + (25-20) ×20=300W, and even if the air outlet 1 of the blower is closely attached to the hair surface, the temperature of the air blown by the blower to the hair surface is maintained at 58 ℃, so that the hair cannot be scalded due to the overhigh temperature.
The motor and the fan are designed in the air duct by the traditional air blower, so that the volume of the air duct is large, the shell is usually designed into an olive shape for beautifying the appearance, and the middle thick part can shield the distance sensor on the handle, which is close to the air duct, so that the distance sensor cannot work normally. Further, the motor 11 and the fan 9 of the blower are designed in the handle 14, so that the blower housing can be designed into a straight cylinder shape, and the blower can not shade the distance sensor 3 near the blower.
In summary, the intelligent blower with the pressure sensor can intelligently judge and control the opening and closing of the blower through the angle information detected by the gyroscope without being controlled by keys, so that the intelligent blower with the pressure sensor has the advantages of simple and modern appearance, convenience in use and capability of avoiding misoperation caused by false touch. Meanwhile, through the cooperation of the distance sensor and the temperature sensor, the power of the heating device is intelligently calculated and controlled, so that the temperature of wind blown to the hair surface by the blower is always kept constant, and the damage to the hair/hair caused by overheat blowing or the influence on health caused by supercooling or unnecessary conflict are avoided.
It is to be understood that the above examples of the present utility model are provided for clarity of illustration only and are not limiting of the embodiments of the present utility model. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments.
