Description

Technical Field

[0001] The utility model relates to a hair dryer, in particular to an intelligent hair dryer with a distance detection function. Background Art

[0002] There are many types of hair dryers, some are used to blow out a large amount of air, ventilate a place, or provide air volume, and some small hair dryers, such as hair dryers for drying wet hair, are basically a daily appliance in every household. A hair dryer is a device that blows out hot air quickly. In addition to drying wet hair in daily use, it is also often used for hair styling, especially in barber shops, and is used very frequently.

[0003] The hair dryer has an air outlet and an air inlet. The external wind enters from the air inlet, and then is heated by the heating device inside the hair dryer to become hot air and blown out from the air outlet. In this case, the air outlet forms a blowing function, and the air inlet forms a suction function. When using a hair dryer, the hairdresser uses the hot air from the air outlet to blow the hair, and uses the suction force of the air inlet to shape the hair, so that the hair can be quickly shaped by alternating hot and cold. Or some hairdressers will directly use the suction force of the air inlet to pull the hair directly into shape.

[0004] However, the air inlet speed of current hair dryers is basically fixed. If users want to increase the suction force of the air inlet, they can only put the hair dryer as close to the hair as possible, which can easily cause the hair to be directly rolled into the hair dryer motor, not only resulting in poor shaping effect, but also easily leading to safety issues. In addition, if the air outlet is too close to the hair, the air outlet temperature is too high, which may burn the scalp layer of the brain. Utility Model Content

[0028] Embodiment 1

[0029] refer to Figure 1-3As shown, a smart hair dryer with a distance detection function includes a casing body 1, one end of the casing body 1 is an air inlet 2, and the other end of the casing body 1 is an air outlet 3. A control board, a heating component and a motor component are arranged in the casing body 1, and the heating component and the motor component are respectively connected to the control board. A distance detection component 4 is arranged in the casing body 1 in the air inlet 2 area, and the distance detection component is connected to the control board. The distance detection component detects the distance between the air inlet and the hair. The control board controls the speed of the motor component according to the distance between the air inlet and the hair detected by the distance detection component, so as to adjust the air intake suction of the air inlet. The control board is a circuit board integrated with a processing chip and necessary electronic components. The speed, opening and closing of the motor component and the heating power of the heating component can be controlled by the control board to realize the regulation and control of the air outlet, air intake and hot air. The corresponding application parameters can be preset at the factory, such as the air inlet distance. Since the distance detector is set in the area where the air inlet is located, the distance between the hair detected by the distance detector and the distance detector is by default equivalent to the distance between the hair and the air inlet. When the distance between the hair and the air inlet is detected by the distance detector, the distance data will be transmitted to the control board. The control board will compare the received current detection distance with the preset distance. If the current detection distance is greater than the preset distance, it means that the current distance between the hair and the air inlet is far. If the wind force is too small at this time, the hair cannot be smoothly sucked up and it is difficult to complete the styling design. At this time, the control will send a command to the motor assembly to increase the speed of the motor assembly, thereby increasing the air intake suction force to ensure that the hair can be smoothly sucked up at a long distance. If the current detection distance is less than the preset distance, it means that the current distance between the hair and the air inlet is relatively close. If the wind is too strong at this time, there is a risk of the hair being sucked into the main body of the casing. At this time, the control board sends a command to the motor assembly to reduce the speed of the motor assembly, thereby reducing the air intake suction force, ensuring that the adsorption force of the air inlet is not too large at a closer distance, thereby preventing the problem of hair being sucked into the main body of the casing.

[0030] The distance detection element is an infrared sensor, a laser sensor or an ultrasonic sensor, and different sensors can be flexibly selected for application.

[0031] Embodiment 2

[0032] refer to Figure 1-3As shown, a smart hair dryer with a distance detection function includes a casing body 1, one end of the casing body 1 is an air inlet 2, and the other end of the casing body 1 is an air outlet 3. A control panel, a heating component and a motor component are arranged in the casing body 1, and the heating component and the motor component are respectively connected to the control panel. A distance detection component 4 is arranged in the casing body 1 in the air inlet 2 area, and the distance detection component is connected to the control panel. The distance detection component detects the distance between the air inlet and the hair, and the control panel controls the rotation speed of the motor assembly according to the distance between the air inlet and the hair detected by the distance detection component, so as to adjust the air intake suction of the air inlet. In this embodiment, one distance detection component is provided, and the distance detection requirement can be met by one distance detection component. Of course, in order to make the detection accuracy higher and realize more precise control, two or more distance detection components can be provided.

[0033] When more than two distance detection members are provided, the two or more distance detection members are on the same plane and are located at different positions of the air inlet 2 of the casing body 1. For example, two distance detection members 4 are provided, one distance detection member 4 is provided on the left side of the air inlet 2, and the other distance detection member is provided on the right side of the air inlet, and they are symmetrically distributed with the center of the air inlet as the reference. When there are multiple distance detection members, they are provided on the same plane, rather than one close to the outside of the air inlet and the others close to the inside of the air inlet, so that the depth of field distance of each distance detection member is different, which makes it easy to get the problem of inaccurate detection. All distance detection members are located on the same plane, and the distance between them and the hair is relatively uniform, ensuring the accuracy of the detection. By providing multiple distance detection members, it can also be ensured that when one of them is damaged, the other distance detection members can still operate normally and complete the detection.

[0034] In addition, a card slot is provided at the air inlet of the housing body, and the distance detection member is carded in the card slot for easy assembly. The outer periphery of the distance detection member is coated with a heat insulation layer to prevent the distance detection member from being damaged by high temperature. The heat insulation layer can be made of heat insulation materials, such as asbestos, or coatings, or other heat-resistant materials.

[0035] Embodiment 3

[0036] like Figure 1-3As shown, a smart hair dryer with a distance detection function includes a casing body 1, one end of the casing body 1 is an air inlet 2, and the other end of the casing body 1 is an air outlet 3. A control panel, a heating component and a motor component are arranged in the casing body 1, and the heating component and the motor component are respectively connected to the control panel. A distance detection component 4 is arranged in the casing body 1 in the air inlet 2 area, and the distance detection component is connected to the control panel. The distance detection component detects the distance between the air inlet and the hair. The control panel controls the speed of the motor component according to the distance between the air inlet and the hair detected by the distance detection component, so as to adjust the air intake suction of the air inlet. A plurality of air inlet holes 21 are arranged in the air inlet 2 area of ​​the casing body 1, and the distance detection component 4 is arranged in the area outside the air inlet hole 21. A closed block 22 is arranged at the center of the air inlet 2 of the casing body 1, and the air inlet holes 21 are arranged around the closed block 21, and the distance detection component is arranged on the closed block. In this embodiment, a circle of air inlet holes is arranged around the sealed block, the sealed block is located in the central area of ​​the air inlet, and a distance detection member is arranged on the outer surface of the sealed block, that is, exposed outside the air inlet. In order to avoid direct interference from the outside, a transparent protective cover can be installed on the periphery of the distance detection member. Of course, the protective cover needs not to affect the normal detection function of the distance detection member, such as a transparent plastic member.

[0037] The distance detection member is installed and connected to the casing body by glue, screws or a snap-fit ​​structure, which can be flexibly selected according to actual assembly requirements to facilitate assembly while ensuring reliable assembly.

[0038] In addition, a temperature sensor is provided in the air outlet of the housing body, and the temperature sensor is connected to the control board. The temperature sensor can sense the air outlet temperature of the air outlet in real time. When the temperature is too high, the control board can forcibly shut down the machine to avoid high temperature scalding hands or hair. Or after detecting high temperature, the control board sends a command to the heating component to reduce the heating power and reduce the air outlet temperature. For the temperature sensor, the number of the temperature sensors can also be selected according to the use environment and the structure of the housing body.

[0039] In addition, the housing body is usually cylindrical, which is more convenient for users to use. The housing body also includes a handle, which the user can hold when using, and various power buttons can be installed on the handle for easy operation.

[0040] The utility model can make full use of the air inlet to style the hair, utilizes the distance detection part arranged in the air inlet area to detect the distance between the air inlet and the hair, and continuously adjusts the wind speed in real time to try to keep the suction force of the air inlet on the hair basically unchanged. The hair will not be unable to be pulled up due to too small suction force, nor will the hair be sucked into the hair dryer due to too large suction force. The hair styling design can be completed conveniently and quickly, and the user experience is greatly improved.

[0041] In specific use, by setting the parameters of the control panel in advance, for example, when the distance between the air inlet and the hair is set to A, the air inlet suction corresponds to the first gear, when the distance between the air inlet and the hair is set to B, the air inlet suction corresponds to the second gear, when the distance between the air inlet and the hair is set to C, the air inlet suction corresponds to the third gear, distance A is greater than distance B, distance B is greater than distance C, the first gear air inlet suction is greater than the second gear air inlet suction, and the second gear air inlet suction is greater than the third gear air inlet suction. According to usage habits, distance A is usually set to the farthest distance. When the distance detection component detects that the current distance between the air inlet and the hair is greater than distance A, it means that the position is far away. If the current position is not the first gear air inlet suction, the control panel will control the motor assembly to increase the speed to form the first gear air inlet suction. By increasing the air inlet suction, the hair farther away can be sucked and pulled up. The above-mentioned distances A, B and C are all range values. When it is detected that the distance between the current air inlet and the hair is within a certain range, the corresponding level of air inlet suction will be executed to ensure the best air inlet suction, complete the adsorption and lifting of the hair, and smoothly carry out the styling design. While completing the hair styling design, it also improves comfort and safety to avoid causing harm to the user.

[0042] It should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
