The utility model relates to the technical field of batteries, in particular to a battery end cover structure and a battery. The battery end cover structure comprises a cover plate and an insulating component, an anti-explosion valve is arranged on the cover plate, and a protruding structure is arranged at the position, close to the anti-explosion valve, of the cover plate. The protruding structure protrudes out of the inner side face, facing the pole group, of the cover plate and is suitable for abutting against the pole group so that a gap can be formed between the pole group and the inner side face of the cover plate. The insulation assembly is arranged on the inner side face of the cover plate, and an avoiding groove is formed in the insulation assembly to avoid the protruding structure. The insulation assembly plays a role in insulation between the pole group and the cover plate. And secondly, after the battery is subjected to thermal runaway, the insulation assembly is melted to cause movement of the pole group due to over-high internal temperature of the battery. At the moment, the bulge structure on the cover plate can support the pole group, so that a gap is formed between the pole group and the inner side surface of the cover plate, the pole group is prevented from shielding or blocking the anti-explosion valve, the risk of explosion of the battery is further prevented, and the safety of the battery is greatly improved.

The utility model relates to the technical field of air conditioners, in particular to a heat dissipation structure, an electric control box, an outdoor unit and heating and ventilation equipment, the heat dissipation structure comprises a heat dissipation plate, the heat dissipation plate comprises a heat conduction plate section and a connecting plate section which are connected together, and the heat conduction plate section is used for exchanging heat with a heat exchange medium; according to the electric control box, the connecting plate section is provided with the heat insulation part, the heat insulation part is used for blocking heat exchange between the heat conduction plate section and the connecting plate section, the problem that condensate water appears in the corresponding power connection area of the heat dissipation plate is solved, therefore, short circuit at the node part is avoided, and normal use of the electric control box is ensured.

The utility model relates to the technical field of metal processing, and discloses a rectifier for electroplating processing, which comprises a shell, a fixing assembly arranged on the left side of the shell, a telescopic assembly arranged on the left side of the shell, an air box fixedly connected to the middle of the left side of the shell, and fixing rods slidably connected to the upper and lower parts of the air box. A fan is fixedly connected to the periphery of the fixing rod, a motor is fixedly connected to the top of the fan, and a plurality of evenly-distributed connecting rods are slidably connected to the front end of the air box. According to the utility model, through the heat dissipation mechanism, the temperature rise during the operation of the rectifier cannot be caused, the overheating problem is further avoided, the performance of electronic components can be influenced by the overhigh temperature, and even the components can be damaged, and through the dustproof mechanism, dust and particulate matters cannot enter the rectifier under the condition that the dustproof mechanism is arranged, so that the service life of the rectifier is prolonged. And dust accumulation on the electronic component and the circuit board is avoided. And short circuit, overheating and damage of elements are not caused.

The invention discloses an electronic atomization device which comprises a main machine assembly and an atomization assembly arranged side by side with the main machine assembly, the main machine assembly comprises a microphone, and the atomization assembly comprises an atomizer and a suction nozzle. The atomizer is provided with an atomization air channel, the atomization air channel is connected with the first air outlet air channel, a wake-up air channel connected with the second air outlet air channel is formed between the main machine assembly and the atomization assembly, the microphone is arranged in the wake-up air channel, the microphone adopts an independent air channel, condensate generated by the atomization air channel cannot flow through the microphone, and therefore the microphone is protected against short circuit. The problems that in the prior art, liquid absorbing cotton is saturated, condensate directly flows out of the air inlet of the air channel or remains in the air channel, and consequently short circuit of the microphone is caused, and the suction experience is affected are solved, and the performance of the product is improved.
