The application provides a high-efficiency cooler and relates to the field of cooling equipment, which comprises a main pipe body, an oil inlet pipe fixedly connected to the left side of the main pipe body, a gas guide pipe fixedly arranged in the cooling pipe, air guide plates fixedly connected to the two ends of the gas guide pipes, an air inlet pipe and an air outlet pipe connected to the two air guide plates respectively, a turbine rotatably mounted to the left side of the inside of the oil inlet pipe, a speed reducer fixedly arranged to the bottom of the inside of the oil inlet pipe, the turbine and the speed reducer in transmission connection, a first gear connected to the right side of the speed reducer through a rotating shaft, a filter cylinder rotatably mounted to the right side of the inside of the oil inlet pipe, a second gear fixedly connected to the left side of the filter cylinder, and four circular filter plates fixedly arranged to the inside of the filter cylinder.

This utility model belongs to the technical field of electronic cigarette devices, and discloses a cartridge structure and a replaceable cartridge-type electronic cigarette atomizing device. The cartridge structure includes a cartridge mouthpiece, an airway sealing assembly, and an atomizing base device. The cartridge mouthpiece is detachably connected to the atomizing base device, and has a cartridge airway communicating with the atomizing base device. The airway sealing assembly is located inside the cartridge airway, extending along the entire length of the airway, and is detachably and sealingly connected to the end of the airway near the atomizing base device. This structure completely fills the airway cavity with the airway sealing assembly. Compared with the traditional method of sealing only the mouthpiece with a silicone T-shaped plug, it significantly reduces the volume of the airway cavity, reduces the flow space of e-liquid during transportation and storage, reduces the risk of e-liquid leakage due to vibration or tilting, and effectively improves the sealing performance and stability and reliability of the product under various usage conditions.

The invention discloses a power distribution control center, and relates to the technical field of low-voltage complete power distribution equipment, and the power distribution control center is characterized in that two ends of a drawer structure are installed in a power distribution cabinet through guide rails, one end, close to a contact groove, of the drawer structure is fixedly connected with a plug and is provided with abutting blocks located on two sides of the plug, and the side end of a ventilation table is provided with an air outlet groove. The side end of the ventilation table is provided with an air inlet main channel, the air outlet groove is communicated with a ventilation cavity formed in the ventilation table, the air inlet main channel is communicated with the ventilation cavity through a rotating groove formed in the ventilation table, the two ends of the overturning plate are rotationally connected with the inner wall of the air outlet groove, the bottom of the overturning plate is provided with a partition plate, and the overturning plate and the partition plate are located on the upper side and the lower side of the air outlet groove respectively. The partition plate is fixedly connected with the inner wall of the ventilation cavity. The beneficial effects are that when each drawer structure is installed in the power distribution cabinet, an independent closed channel is formed by the corresponding separator plate and the turnover plate, so that air flow flowing out of the inner cavity of the air inlet main channel is ensured to be in contact with the drawer structure through the closed channel.

The utility model relates to a kind of multifunctional outdoor oven, including furnace body, cover, pizza tray assembly, heating piece and baking tray, the upper end of furnace body is equipped with open mouth, cover is buckled on open mouth, cover and furnace body cooperation form cooking cavity, the front side of furnace body is equipped with opening, pizza tray assembly includes pizza tray and guard plate, pizza tray is put into furnace body across opening, guard plate covers on opening, the lower of pizza tray is equipped with heating piece, the upper of pizza tray is equipped with baking tray, and heat conduction passage is equipped between pizza tray and furnace body inner wall. By setting pizza tray assembly, baking tray and heating piece, oven not only has the function of baking pizza, but also can fry other food, greatly improve the practicability of equipment, meet the diversified cooking needs of user, cooking process is more efficient, convenient, realize a oven can meet the different cooking needs of multiple food, reduce the number of cooking equipment, save user cost, it is convenient to store.

This invention discloses a closed-type built-in cylindrical reverse airflow coordinated collision filter cartridge cleaning system, including a shell, several filter cartridges installed inside the shell, a cylinder installed inside the filter cartridges, and a first cover plate, a second cover plate, a third cover plate, and a cleaning cover plate for controlling the internal gas flow path. The filter cartridge cleaning system of this invention has a filtration state and a cleaning state. In the filtration state, the openings at both ends of the cylinder are open, not affecting the normal operation of the filter cartridges. Gas enters from the air inlet, is filtered by the filter cartridges, and flows out from the air outlet. In the cleaning state, the openings at both ends of the cylinder are covered by the first and second cover plates, and are in a closed state. Through the cooperation of the third cover plate and the cleaning cover plate, external gas enters from both ends of the filter cartridges to clean them. During cleaning, gas enters from both ends of the filter cartridges, allowing for uniform cleaning. Furthermore, because the cylinder is in a closed state, the internal gas flow space of the filter cartridges is reduced, further improving the cleaning efficiency.
