The mobile air conditioner capable of changing the cold air outlet direction and provided with the obliquely-installed coaxial cold and hot air ducts is compact in structure, small in size, low in manufacturing cost and use cost, convenient to assemble, high in air outlet speed, long in air supply distance, low in working noise, good in use effect and long in service life.

The bulk particle material containing device comprises a containing bin, and a bottom plate is installed at the bottom of the containing bin; the bottom plate comprises a sliding way arranged on the bottom face of the inner side of the containing bin and a first supporting bottom plate movably installed on the sliding way, a second supporting bottom plate is arranged on the sliding way, the first end of the second supporting bottom plate is hinged to the end of the first supporting bottom plate, and the second end of the second supporting bottom plate can vertically move and protrude upwards. And then one end of the first supporting bottom plate is driven to horizontally move along the sliding way, and a discharging space is formed. The double-side unloading device is provided with the rectangular containing cavity, the transportation volume is large, manufacturing and mounting are convenient, the double-side unloading device can be conveniently modified to be used for transporting other objects, double-side simultaneous unloading can be achieved, the unloading efficiency is high, no material residues exist after unloading, the structure is simple and compact, and the application prospect is wide.

The utility model provides a kind of valve group and compressor of miniaturization reciprocating compressor, it is related to compressor field, to the problem that the temperature of existing small compressor cylinder head is too high, gas flow resistance increases and leads to efficiency reduction, by the offset structure of valve plate on the valve plate subassembly suction hole, enlarge suction valve port flow area, reduce suction resistance, reduce the pressure loss and friction heat in suction process, to reduce suction overheating, from the source to relieve cylinder head overheating problem, allow to adopt smaller size cylinder hole, meet the demand of compressor miniaturization, the valve tongue both sides of suction valve piece are provided with contraction part to form waist, exhaust hole is arranged between two sides waist, adapt to the compact space of miniaturization valve group, suction muffler outlet and cylinder cover keep apart, leave gap, cut off the heat conduction path between cylinder cover and suction muffler, form heat insulation, reduce suction overheating, reduce cylinder head temperature benign cycle, improve miniaturization reciprocating compressor efficiency.

This utility model provides a vibration structure for a spherical graphite vibratory grinding device, belonging to the technical field of spherical graphite vibratory grinding devices. The vibration structure includes: a vibratory body, a vibration excitation device, a support base, a transmission shaft, an adjustment mechanism, and a sealing cover. The vibratory body is cylindrical, with a spherical grinding cavity inside, the inner wall of which is made of stainless steel. The support base is fixedly mounted on the ground, and its upper surface is connected to the bottom of the vibratory body via a shock-absorbing spring assembly. The vibration excitation device includes an eccentric wheel and a drive motor, which is fixedly mounted on the side wall of the support base. The output shaft of the drive motor is connected to the transmission shaft via a coupling. This invention solves the technical problems of uneven grinding, poor vibration control accuracy, and insufficient equipment stability in existing spherical graphite grinding devices.

The invention discloses a drinking water preparing and filtering device and method based on a magnetized filter element, and relates to the technical field of filtering. A filter cartridge; a first filter plate, a second filter plate, a third filter plate and a fourth filter plate; the telescopic unit is arranged on the connecting base and used for driving the first filter plate, the second filter plate and the third filter plate to move in the direction away from the fourth filter plate, so that the shaftless spiral piece is in an elastic extension state. According to the invention, when foreign matters and impurities are cleaned, a telescopic unit drives a first filter plate, a second filter plate and a third filter plate to move in a direction far away from a fourth filter plate, so that a shaftless spiral sheet is elastically stretched and deformed, and gaps between activated carbon particles and magnetized particles are increased; foreign matters and impurities can flow out to the water outlet through gaps between the activated carbon particles and the magnetized particles, so that the foreign matters and impurities are removed, the replacement period of the filter element is prolonged, and the replacement frequency of the filter element is reduced.

The invention relates to the technical field of battery packs, in particular to a battery pack for an energy storage power station and a protection system thereof.The battery pack comprises a battery cell module and a battery pack shell, a battery monomer sealing shell is arranged outside the battery cell module in a packaging mode, and the battery cell module and the battery monomer sealing shell are both located inside the battery pack shell; a pressure-sensitive circular groove is formed in the upper surface of the battery monomer sealing shell in a penetrating manner, and a floating disc body is arranged in the pressure-sensitive circular groove; according to the battery pack for the energy storage power station, through structural cooperation of the floating disc body, the laser receiver, the laser transmitter and the like, the internal pressure condition of the battery monomers can be visually monitored, and through vertical floating of the floating disc body, the internal pressure fluctuation amplitude of the battery monomers can be weakened.
