This utility model relates to an integrated miniaturized air-cooled electronic chassis, including a chassis with a cubic structure open at both the front and rear ends. A front cover assembly and a rear cover assembly are respectively installed on the front and rear open surfaces, and electromagnetic shielding strips are provided in the installation gaps between the chassis and the front and rear cover assemblies. A circuit module is installed inside the chassis, and curved heat dissipation fins are installed on the top and bottom. An air inlet is provided at the rear corresponding to the heat dissipation fins. Air outlets are provided on the top and bottom of the front cover assembly. A fan assembly is installed on the rear cover assembly. This application utilizes the fan assembly, rear cover assembly, chassis, heat dissipation fins, and front cover assembly to form an effective air-cooled heat dissipation channel, which can quickly dissipate the heat generated by the circuit modules inside the chassis, greatly improving the chassis's heat dissipation efficiency. Simultaneously, the electromagnetic shielding strips effectively reduce electromagnetic interference, improve the stability of the electronic equipment inside the chassis, and ensure that the chassis can operate normally in complex electromagnetic environments.

This utility model discloses a warp-knitted fabric, relating to fabric technology. The key technical points are: it includes a base layer, which is woven from GB1 and GB2 guide yarns to form a warp-knitted mesh structure. The diameter of the GB1 guide yarn is larger than that of the GB2 guide yarn, and short fibers are provided on the outer periphery of the GB1 guide yarn. A moisture-wicking yarn is added to the base layer, spanning the warp-knitted mesh structure. The warp-knitted mesh structure of this utility model effectively ensures the fabric's breathability, and the moisture-wicking yarn effectively transfers excess sweat to drier areas of the base layer, thus ensuring better sweat absorption and improving fabric comfort. The moisture-wicking yarn, made from twisted C-shaped polyester fibers, further enhances its ability to transfer excess sweat.

This invention discloses an air filtration and disinfection structure for processing dried beef, comprising at least one air filtration device installed at the bottom of a drying cabinet for filtering and disinfecting air. The air filtration device includes a coarse filter cylinder and a fine filter cylinder sealed together by bolts. An air inlet is opened on the side of the fine filter cylinder. An inner cylinder is fitted inside the coarse filter cylinder, and an ultraviolet lamp column is installed inside the inner cylinder, with one end of the ultraviolet lamp column sealed and penetrating the fine filter cylinder. A spiral plate is fitted onto the outer side of the inner cylinder near the coarse filter cylinder section. An adhesion mechanism is provided on the inner wall of the coarse filter cylinder, comprising an adhesion paper and a knob. Rotating the knob causes the adhesion paper to rotate inside the coarse filter cylinder. This invention can effectively achieve a three-stage filtration and disinfection effect on the air while ensuring the actual airflow, reducing the difficulty of actual maintenance.

The utility model discloses an electric generator wind circulation filtering cooler which comprises a wind collecting cover and a centrifugal fan, the wind collecting cover is arranged in an inner cavity of an electric generator in a covering mode, the side wall of the wind collecting cover is provided with an exhaust port and an air inlet, the centrifugal fan is arranged in the exhaust port, the air inlet is provided with filtering cotton and a dust removing unit, and the filtering cotton is connected with the wind collecting cover through a vibration unit. According to the wind circulation filtering cooler of the generator, the wind collecting cover and the centrifugal fan are utilized, after dust in external air is filtered through the filter cotton, clean airflow enters the inner cavity of the generator from the air outlet to cool the inner cavity of the generator, high-temperature air is pumped out through the wind collecting opening of the centrifugal fan, the heat dissipation effect of the generator is guaranteed, and the service life of the generator is prolonged. Meanwhile, pulse high-pressure air flow is blown out to the filter cotton through the air blowing opening, dust accumulated on the surface of the filter cotton is blown away, the support and the filter cotton move along with the pulse air flow to generate vibration in cooperation with the spring, and dust on the filter screen can fall off easily.

The invention discloses a noise reduction food processor which comprises an air outlet structure arranged in an air outlet channel, the air outlet structure comprises at least two flow channels, each flow channel is internally provided with at least two communicated valve units, each valve unit comprises a flow distribution column, a first enclosure wall and a second enclosure wall, and the first enclosure wall and the second enclosure wall are arranged on the two sides of the flow distribution column. A first branch flow channel is formed between the first surrounding wall and the flow dividing column, a second branch flow channel is formed between the second surrounding wall and the flow dividing column, a flow dividing position is formed at an inlet of the valve unit, and an obtuse included angle is formed between a tangential path extending from the flow dividing position to the first branch flow channel and a tangential path extending from the flow dividing position to the second branch flow channel. The airflow flowing in from the flow dividing position comprises main airflow flowing along the first branch flow channel and auxiliary airflow flowing along the second branch flow channel, and the main airflow and the auxiliary airflow intersect at an acute angle. According to the food processor, the optimized air outlet structure is adopted, and the heat dissipation effect and the noise reduction effect can be optimized in the heat dissipation process of the motor.
