Abstract: This application relates to the field of motor technologies, and provides a motor rotor, a drive motor, and an electric vehicle. In the motor rotor, a rotor core with at least two protruding components is designed. At least two magnetic steels and at least two sheets are disposed in grooves between the at least two protruding components and then coupled to the rotor core with a rotor pressing plate. In addition, one SMC sheet is stacked on each of the magnetic steels, so that an eddy current loss of a permanent magnet can be effectively reduced. Each of the magnetic steels is disposed in a groove between protruding components, and the SMC sheet is added, so that a saliency ratio is increased, a reluctance torque ratio is increased, and a quantity of magnetic steels for use is reduced.

Abstract: A multifunctional handle-type electrical blow dryer includes a temperature measuring device installed on a housing of the electrical blow dryer for measuring a temperature at the housing of the electrical blow dryer to obtain and output a corresponding on-site measured temperature; an on-site alarm device for performing a corresponding voice alarm operation when the on-site measured temperature is over-limit; a data testing mechanism includes an ultrasonic transmitting device, an ultrasonic receiving device and an air-temperature testing device. The ultrasonic transmitting device is installed on the high definition camera for transmitting an ultrasonic signal towards the ground and recording the time of transmitting the ultrasonic signal. The ultrasonic receiving device is installed on the high definition camera, near the ultrasonic transmitting device, for receiving the ultrasonic signal transmitting from the ultrasonic transmitting device to the ground and reflected from the ground.

Abstract: The present invention relates to a metal hair dryer with an adjustable air volume. The hair dryer comprises: an air-blocking plate is used for adjusting the air intake volume of the hair dryer; a field data extraction device comprising an infrared transmitter, an infrared receiver, an ARM11 processor and an extraction controller, wherein the infrared transmitter is located on a data collection device and is used for vertically transmitting an infrared signal downwards, and the infrared receiver is located beside the infrared transmitter and is used for receiving the infrared signal, which is reflected back; and an air-blocking plate driving device is used for enabling an operation on the air-blocking plate when the human body detection device determines that there is a human body. By means of the present invention, an effective authentication mechanism is introduced for the hair dryer.

Abstract: A centrifugal protective hair blower, comprising a plastic shell for wrapping powered devices of the blower, wherein the plastic shell is made of polycarbonate casting; an electric heating device which is arranged in the plastic shell of the hair blower, composed of a two to three sections electric heating wire, and is used to control the blowing temperature of the hair blower; a hemispherical picture-shooting mechanism, which includes a trailing measurement device, an image interception device, a data analysis device, a DC drive motor, an optical filter, optical lens and an image sensing device; an electric heating device, which is connected with a vector analysis device, and is used to reduce the blowing temperature of the hair blower when the target type is a cat, a dog or a rabbit. Through the present invention, it is capable of preventing the hair blower from causing unwarranted injury to surrounding pets.

Abstract: The present invention relates to a child-proof smart hair dryer, comprising: an AC permanent magnet motor for driving the fan blade structure of the hair dryer to rotate; the fan blade structure, while rotating, forming a centrifugal airflow in the air duct; a hemispherical photographing mechanism, which includes a trailing measurement device, an image capture device, a data analysis device, a DC drive motor, an optical filter, an optical lens, and an image sensing device, wherein the image sensing device is set on the air duct, and is used to take an image of the front of the air duct; a trailing measurement device is used to perform an image content measurement to determine whether a trailing pattern appears in the image in front of the air duct, and sending a content trailing signal when a trailing pattern appears.

Abstract: A page display method is provided. The method includes determining a first page based on a first operation on a client; and obtaining, in response to the first operation on the client, current scenario information of the client and a first target page set that is generated according to a page jump historical record of the first page. The method also includes determining a second target page set corresponding to the current scenario information according to a correspondence between scenario information and target pages in the first target page set; creating a corresponding page-entry control for at least one page in the second target page set; and displaying the first page and the page-entry control for at least one page.

Abstract: An axial-flow blow dryer based on motor speed regulation includes: a motor speed regulation device provided for users to select air volume and hot air temperature; a current capture device for executing a panoramic shooting of the blow dryer; an authorization verification device for executing a characteristic matching of an image characteristic of a self-regulation enhanced image based on a predetermined authorized person's face characteristic. If the characteristic matching has a percentage value exceeding a predetermined percentage threshold, then an authorized person existence signal will be issued; a motor driving device for stopping the response of the motor speed regulation device to its various operations when receiving the authorized person non-existence signal, so that the present invention can prevent any unauthorized use of the blow dryer effectively.
