This utility model relates to the field of electricity meter technology, and particularly to a high-efficiency heat dissipation structure for electricity meters. It includes an electricity meter housing, a cover hinged to the front left end of the housing, a fixed lug fixedly connected to the upper end of the housing, and a fixed plate fixedly connected to the lower end of the housing. Both the front ends of the lugs and the fixed plate have through holes. Mounting components are fitted onto the middle left and right ends of the housing. This high-efficiency heat dissipation structure activates the cooling fan within the heat dissipation component when the load increases and high-efficiency heat dissipation is required. The fan operates stably within the fixed frame via a mounting rod and a mounting base, utilizing the gap between itself and the inner wall of the fixed frame to generate an adsorption force. This force quickly introduces internal heat into the heat dissipation component through the first heat dissipation groove, heat dissipation fins, and mounting holes, and finally dissipates efficiently through the second dust filter, significantly accelerating the heat dissipation speed.

The utility model relates to a kind of clean sewage separation pet water dispenser, including water purification device, sewage tank, water tray, water supply assembly and water pump are provided in water purification device, water supply assembly is set apart and includes mainboard and the control unit and first conductive structure set on mainboard, water pump is electrically connected in mainboard.Sewage tank and water drinking tray are set in the same side of water purification device, water drinking tray is covered in the upper of sewage tank, and water drinking tray has circulating pump and second conductive structure.Water pump is extracted to water drinking tray in the clean water in water purification device for pet drinking, circulating pump opens to make the water in water tray circulate and flow, sewage tank collects dirty water in water tray, water purification device and sewage tank are separately arranged to realize clean sewage separation.Water tray in the application is installed in the side of water purification device by magnetic attraction, and first conductive structure and second conductive structure are electrically connected, realize that circulating pump is electrically connected with mainboard, and thus the control unit on water supply assembly can control the working condition of water pump and circulating pump together.

The utility model relates to the technical field of filters, in particular to a small-size high-voltage filter. Aiming at an application scene with strict space limitation, the filter adopts the design of a 6061 aviation aluminum integrated milling shell, a polyether-ether-ketone (PEEK) insulating plate, an output interface formed by combining a gold-plated copper platform with a flexible lead and the like, so that light weight and miniaturization are realized. Main devices comprise a common-mode inductor, a differential-mode capacitor, a common-mode capacitor and a bleeder resistor to form a first-order low-pass filter circuit, EMI interference of 10 kHz to 10 MHz is effectively restrained, and the electromagnetic compatibility requirement (GJB151ACE102) under the working condition of direct current 540V / 50A is met. The size of the product is only 40cm < 3 >, the weight is 128g, and the product has high insulativity, low contact resistance and excellent vibration resistance, and is suitable for the fields with strict requirements on size and reliability, such as aerospace and the like.
