The present invention relates to an air-conditioning apparatus for a vehicle, and intends to improve ventilation of air inside a vehicle so as to reduce the temperature difference between the front and the back seats by means of uniformly blowing cooling or heating air toward each of the back seats, so that each of the back seats can be maintained at a uniform temperature. To this end the present invention provides a front seat air-conditioning device arranged in the front seat area in a vehicle with an auxiliary blower for improving ventilation of air by sucking and re-blowing the air in the vehicle so as to ventilate the cooling or heating air of the front seat air-conditioning device from the front seat area to the back seat area. Additionally, a back seat air-conditioning device is arranged in one of the side walls of the vehicle in the back seat area so as to cool or heat the back seat area, and the auxiliary blower is arranged so as to blow air toward to the back seat area to mix with the cooling or heating air supplied from the back seat air-conditioning device to the back seat area.

The present invention relates to an air conditioner for a vehicle, and aims to improve the circulation of air in the vehicle to reduce front-to-back The temperature difference between the seats. To this end, the present invention provides a front seat air conditioner arranged in a front seat area in a vehicle, the front seat air conditioner having an auxiliary blower to suck in and blow out air in the vehicle again to circulate heated or cooled air of the front seat air conditioner from the front seat area to the rear seat area for improved air circulation. In addition, a rear seat air conditioner is provided in one of the side walls of the vehicle in the rear seat area to cool or heat the rear seat area, and an auxiliary blower is provided to blow air to the rear seat area to communicate with air from the rear seat air conditioner. Mixing of cooled or heated air supplied to the rear seat area.

The present invention provides a ceiling-mounted air-conditioning indoor unit, which includes a shell with a circular air inlet and an air supply port. The bottom wall of the shell around the air inlet extends radially outward from the edge of the air inlet and gradually slopes downward. The drainage surface is a rotary surface coaxial with the air inlet; the laminar flow fan is arranged in the casing, including a plurality of annular discs arranged in parallel and spaced apart and fixedly connected to each other, and the axes all extend vertically; the flow guide is arranged at the inlet At the tuyere, the outer peripheral surface is a rotary surface that gradually expands radially outward from top to bottom and is coaxial with the air inlet to guide the air to flow to the air inlet through the gap between the outer peripheral surface of the air guide and the bottom surface of the shell; From the inside to the outside, it includes a smoothly connected arc-shaped transition section, an arc-shaped booster section, and an arc-shaped expansion section; The lower arc segment; the distance between the top of the arc transition segment and the top of the lower arc segment is smaller than the distance between the bottom end of the arc extension segment and the bottom end of the lower arc segment.

The invention relates to the technical field of ore dressing devices, and concretely relates to a stacked modular high-frequency screening machine. The bottom ends of screen boxes are rotationally connected with a lower supporting beam; outer sleeves are connected to fixed blocks arranged at positions, close to the top ends, of the two sides of the screen boxes; a first spring is connected betweenthe inner end of an inner sleeve rod in each outer sleeve and the inner wall of the outer sleeve; sliding blocks are clamped on an upper supporting beam in a sliding manner; connecting rings rotationally connected with the inner side surfaces of the sliding blocks is sleeved and matched with a connecting short column at the top end of the inner sleeve rod; the power end, provided with a micro motor, of the bottom end of the upper supporting beam is connected with a screw in threaded sleeving connection with the sliding blocks; a corrugated hose is connected with the bottom ends of the lower surfaces of the screen boxes; a feeding groove is connected to the top end of an inner cavity of each screen box; the corrugated hose is connected with an undersize product collecting barrel; rigid battens connected with the front surface and the back surface of a flexible guide barrel at the bottom end of a feeder are hinged to rotating plates respectively; and second springs are connected betweenthe lower surfaces of rotating plates and a connecting table on the inner wall of the feeding groove. The problem that the inclination angle of the screen surface of the stacked screening machine isdifficult to flexibly adjust is solved.

The invention discloses a preparation method of powder metallurgy tool and mould steel. The preparation method combines the advantages of vacuum induction melting, inert gas atomized powdering process and powder metallurgy technology, and comprises the steps of utilizing gas atomized powdering equipment to melt tool and mould steel, preparing high-quality tool and mould steel powder with little porosity powder, little nonmetal inclusion and a small size through an optimally designed negative pressure powdering process, and preparing high-quality powder metallurgy tool and mould steel ingot through further thermal dynamic degassing, sheathing and hot isostatic pressing.

A high pressure resistance body element superior in heat resistance, anti-dielectric breakdown property, anti-shock property, and durability, and most convenient for maintenance, inspection, servicing, and replacement repair. It is composed of a cylindrical outer sleeve of metal, a coil-like resistance heating wire stretched between the inner ends of electrode bars respectively inserted in the outer sleeve from the opposite ends thereof, an insulator filled between the resistance heating wire and electrode bars and the inner wall surface of the outer sleeve, and baked, and insulation sleeves removably fitted to the regions close to the opposite ends of the outer sleeve bridgewise supported at the opposite ends thereof by disposition plates to extend through the latter.

The invention discloses a beauty stick that belongs to the technical field of beauty equipment. The beauty stick comprises a handle and a guide pipe, wherein the guide pipe is fixedly connected with the end face of the handle; one end of the guide pipe away from the handle is rotationally connected with a mounting shell; the mounting shell is respectively connected with a fixed shell and a storagetube; the side wall of the fixed shell is provided with a plurality of uniformly distributed mounting grooves; the mounting groove is connected with a massage column through a U-shaped rod piece; theU-shaped rod piece is connected with a conduction pipe through a sleeve; one end of the conduction pipe away from the sleeve is connected with a storage pipe; In the beauty stick, the operation is convenient, the double rotation of the mounting shell and the massage column is utilized, the body surface is effectively massaged while beauty care solution is evenly applied to the body, so as to improve the absorption of the skin to the care solution.

The invention discloses a double-row quenching method, which relates to the field of metallurgical roller quenching machine equipment. The second group of gap nozzles of the quenching machine are changed from a sub-chamber water spray to a through-chamber water spray. The damping structure makes the water flow evenly swirled and sprayed out. The invention changes the second group of slit nozzles of the quenching machine from the original sub-cavity water spraying to the through-cavity water spraying, and makes a damping structure design inside the header, so that the water flow can be evenly sprayed after gyrating, thereby solving the problem of quenching machine Water cooling uniformity problem.
