3results about How to "Keep it clean for a long time" patented technology

The application provides a material with glass-like texture and a preparation method and an electronic device. The preparation method of the material with glass-like texture comprises the following steps: providing a substrate layer, the substrate layer comprising opposite first and second surfaces; strengthening the first surface of the substrate layer to form a hardened layer; performing UV transfer on the hardened layer to form a texture layer on the hardened layer; and printing the second surface of the substrate layer with printing paint to form a printed layer with a set color. The material with glass-like texture has hardness and texture similar to glass and a required color appearance effect, and meets the product requirements of users. The material can keep clean for a long time and maintain the appearance effect of the product for a long time through the AF layer.

This invention relates to the field of water pollution control technology and discloses a reservoir cyanobacteria treatment device for water pollution control. The device includes a floating platform, a temperature sensor, a pH sensor, an aeration pipe, a cleaning component, an air storage tank, and a triggering mechanism. The temperature and pH sensors are fixed to the floating platform and inserted downwards into the water. The aeration pipe is located below the floating platform, and its aeration intensity is dynamically adjusted according to the detected temperature and pH values. The air storage tank is connected to the aeration pipe via an inflation pipe, and its air storage rate is positively correlated with the aeration intensity. The triggering mechanism activates the cleaning component to clean the sensor surface when the air pressure inside the air storage tank reaches a set threshold. This invention, when water quality deteriorates and requires increased treatment efforts, simultaneously enhances the cleaning frequency of the sensors, ensuring the accuracy of monitoring data and improving the effectiveness of water pollution control and the reliability of system operation.

The utility model discloses a dustproof curtain, and particularly relates to the technical field of curtains, the dustproof curtain comprises a mounting plate, the upper part of one surface of the mounting plate transversely extends to form two first rotating seats, the two first rotating seats are jointly and rotationally connected with a horizontally arranged winding drum, curtain cloth is wound on the winding drum, and rotating flapping blades parallel to the winding drum are arranged below the winding drum; one end of the winding drum is coaxially and fixedly connected with a motor, the other end of the winding drum is coaxially and fixedly connected with a first transmission wheel, one end of the rotary beating blade is coaxially and fixedly connected with a second transmission wheel, and the first transmission wheel and the second transmission wheel are jointly sleeved with a transmission belt; the mounting plate is provided with an outer cover which covers the winding drum and the rotary flapping blades simultaneously, a dust suction pipe is transversely inserted into the bottom of an inner cavity of the outer cover and provided with a thin seam facing the curtain cloth, and the end, extending out of the outer cover, of the dust suction pipe is communicated with a dust suction mechanism, so that the curtain can be kept clean for a long time, and manpower and time consumed for cleaning the curtain are reduced.
