Abstract: A heat collecting pump includes: a flow guide member, including a flow guide body and a flow guide blade, wherein the flow guide blade is disposed on an outer peripheral wall of the flow guide body; a heating member, disposed on a periphery of the flow guide member and spaced apart from the flow guide blade. The flow guide blade enables water to flow along the outer peripheral wall of the flow guide body to form a first whirlwind flow and to further form a second whirlwind flow in a gap between the heating member and the flow guide blade. Projections of velocity directions of the first whirlwind flow and the second whirlwind flow on a reference plane perpendicular to the axial direction of the flow guide body are in opposite directions; and the second whirlwind flow removes bubbles gathered on the heating member.

Abstract: A cyclone separator in a dishwasher includes a first housing, a second housing provided inside the first housing, a first filter piece provided inside the second housing, and a back flow part. A waste collection chamber is provided between the second housing and the first housing. The first filter piece encloses and forms a first filter chamber. A flow passage is provided between the first filter piece and the second housing. The flow passage is in communication with the first filter chamber via filter holes, and the waste collection chamber is in communication with the flow passage. An inlet pipe is in communication with the flow passage. A flow medium enters the cyclone separator via the inlet pipe, and forms a cyclone in the flow passage. An outlet pipe is in communication with the first filter chamber, and the flow medium exits the cyclone separator via the outlet pipe.

Abstract: A heating pump includes a driving electric motor; a pump case, wherein a pump cavity and a heating cavity are defined in the pump case, the pump cavity and the heating cavity are roughly arranged side by side in an axial direction and are in communication by means of a communication channel, and a water inlet and a water outlet are formed in the pump case; an impeller arranged in the pump cavity; and a heating member arranged in the heating cavity. Therefore, not only is the size of the heating pump favorably reduced, the impeller may also be prevented from being radiated at a temperature by the heating member, such that the premature aging of the impeller may be prevented, and thus, the usage performance of the heating pump may be improved.

Abstract: A vacuum cleaner and a fan assembly that includes a shell, a rotation shaft, a first impeller, a diffuser and a second impeller. The shell includes an air inlet and an air outlet in communication with each other. The rotation shaft is arranged in the shell and extends from the air inlet to the air outlet. The first impeller is arranged on the rotation shaft and located at a side of the air inlet. The diffuser is arranged in the shell and located at a side of the air outlet. The second impeller is arranged on the rotation shaft and located between the first impeller and the diffuser. The fan assembly may reduce working noise of the fan assembly while ensuring an air supply capacity of the fan assembly, and may reduce a radial size of the fan assembly, and may improve gas flow efficiency.

Abstract: A counter-rotating fan, comprising two impellers and a motor. The motor is used for driving the two impellers to rotate. The two impellers are axially spaced apart from each other, and are divided into a first-stage impeller and a second-stage impeller. When the counter-rotating fan operates, airflow is blown to the direction of the second-stage impeller by means of the first-stage impeller. At least one impeller has turns of blades arranged in the radial direction of the impeller. Blades of each turn are spaced apart from each other around a hub of the impeller, and a spacer ring is connected between two adjacent turns of blades. The counter-rotating fan is stable in rotation and good in cooling effect, it is not easy to deform, and the wind is strong in the center.

Abstract: The present disclosure provides an air conditioner outdoor unit that includes: a motor having first and second output shafts; a first-stage fan blade connected to the first output shaft; a second-stage fan blade connected to the second output shaft. The motor is configured to drive the first-stage and second-stage fan blades to rotate, and rotation directions of the first-stage and second-stage fan blades are opposite. The motor is located between the first-stage and second-stage fan blades, or on the same side of the first-stage and second-stage fan blades. The outdoor unit is provided with a motor, and first-stage and second-stage fan blades, so that the motor drives the first-stage fan blade to rotate through the first output shaft, and drives the second-stage fan blade to rotate in the opposite direction through the second output shaft. By recovering the rotational energy of the airflow, higher wind pressure is achieved.

Abstract: An ambient light parameter is acquired by detecting ambient light of a surveillance area. When there is a target object in the surveillance area, a movement distance of the target object is detected. When the ambient light parameter meets an ambient light condition and the movement distance of the target object is no less than a distance threshold, the ambient light parameter is changed by adjusting screen brightness of a display device according to the ambient light parameter. A face image of the target object after the ambient light parameter has been changed is acquired. A comparison result of comparing the face image to a preset image is acquired. A face recognition result is acquired according to the comparison result.

Abstract: Provided are a method and device for detecting a living-body, and a storage medium. The method includes that: a first image captured by a first camera is acquired, and face detection processing is performed on the first image; a second image captured by a second camera is acquired responsive to detecting that the first image includes a face, where the first camera and the second camera are different types of cameras; and face detection processing is performed on the second image, and responsive to detecting that the second image includes a face, a living-body detection result is obtained based on a matching result of the face detected in the first image and the face detected in the second image.
