The invention relates to wafer heat treatment equipment which comprises a loading chamber and an air supply pipe. The air supply pipe is connected with the loading chamber to supply the loading chamber for air; the wafer heat treatment equipment also comprises at least two exhaust pipes connected with the loading chamber, which exhausts air in the loading chamber. The air exhaust speed of the wafer heat treatment equipment is quicker and comparatively little air is left.

A kiln including a stove and a heat source wherein the stove includes a chamber, an air guide structure, an exhaust pipe and a heat storage member. The chamber includes a cavity, an entry, and an air outlet. The air outlet is located between a top of the front section of the cavity and the entry. The air guide structure communicates with the air outlet and includes a guide plate. The exhaust pipe is disposed above the guide plate, and an exhaust channel is formed by the guide plate of the air guide structure and the exhaust pipe. The heat storage member covers an exterior of the cavity which is corresponding to the top of the front section of the cavity, and contacts the air guide structure. The heat source is disposed in the stove and adapted to heat the cavity.

The invention discloses a compensation type ventilator oxygen supply method and the ventilator, wherein the compensation type ventilator oxygen supply method comprises the following steps: when inhaling, the main oxygen supply pipeline and the auxiliary oxygen supply pipeline work at the same time; , stop the oxygen supply of the main oxygen supply pipeline and the auxiliary oxygen supply pipeline, and resume the oxygen supply of the auxiliary oxygen supply pipeline when the exhalation weakens; when inhaling, open the main oxygen supply pipeline, and the main oxygen supply pipeline and the auxiliary oxygen supply pipeline work at the same time. The ventilator oxygen supply method in the present invention and the ventilator provide a small amount of oxygen in the second half of exhalation by setting the auxiliary oxygen supply pipeline, which is used to make up for the oxygen required by the user during the lag time of the ventilator inducing the inhalation airflow To avoid the situation that the user should be struggling to inhale due to the lag of inhalation and oxygen supply, and to give the user a better breathing experience.

The invention discloses a plasma display screen vacuum seal and exhaustion method and a device thereof, aiming at solving the problems of low vacuum seal and exhaustion efficiency, low vacuum degree inside the screen, which results in impure working gas, and high requirements on the processing technique of seal and exhaustion devices on current color plasma display screens. The invention introduces a vacuum seal and exhaustion furnace to enable a color plasma display screen to be vacuumized so as to get rid of the impurity gas at the time of sealing, and meanwhile, the temperature rising method and the exhaustion method greatly improve pumping speed. The desorption vacuum speed of the gas adsorbed on the display screen is also greatly improved and the vacuum degree of the PDP display screen is greatly improved, nearly improving efficiency by one half. Requirements on processing technique of the seal and exhaustion furnace are lowered, the quality of the PDP display screen is improved and the energy consumption during the production is reduced.

The invention relates to an air-conditioning outdoor unit and a piping system of the air-conditioning outdoor unit. The piping system comprises an exhaust pipe, wherein one end of the exhaust pipe is connected with a working port of a four-way valve; the other end of the exhaust pipe is connected with a compressor; a U-shaped pipe section is arranged at the lower part of the exhaust pipe; and a silencer is arranged on one side, close to the compressor, of the U-shaped pipe section. According to the piping system of the air-conditioning outdoor unit, the silencer is arranged on a section, far away from the compressor, of the exhaust pipe; the whole piping system only comprises the single silencer; the silencing performance of the silencer is better than that of the existing silencing structure; the silencer can also serve as a counter weight of the exhaust pipe at the same time; and the whole piping system is low in cost and high in efficiency.

The invention relates to the technical field of humidification equipment for microbaric oxygen chambers and intelligent control, and discloses a non-return type humidification device for microbaric oxygen chambers, which solves the problem that the humidification devices for microbaric oxygen chambers currently on the market not only waste It is also prone to local high or low humidity, poor humidification effect, increased oxygen use cost and prone to problems of high or low humidity inside the micro-pressure oxygen micro-pressure oxygen chamber; including base, the upper surface of the base is provided with a slide rail, and the upper surface of the slide rail is slidably connected with an electric slider, and the upper surface of the electric slider is provided with a card slot; the present invention has the function of horizontal movement and can quickly improve the micro The humidity in the compressed oxygen and micro-pressure oxygen chamber improves the gas exhaust rate after humidification and realizes that the humidification equipment has a non-return design function, intelligent water addition and timely charging, and intelligent opening or closing functions. The advantage is that the device has a simple structure, strong practicability and novelty, and is suitable for being widely promoted and used.

The invention relates to a vacuum exhaust system for die casting. The vacuum exhaust system is used as peripheral equipment of a die casting machine in vacuum die casting process, and is characterized in that an electromagnetic valve controlling the on-off switching of a vacuum pipeline and a filter connected in series with the electromagnetic valve adopt the mode of multiple parallel connection,so that exhaust capacity is increased; and element groups connected in parallel are arranged near a static template of the die casting machine so as to shorten the length of a pipe between the element groups and a die and increase the reaction of a casting die cavity to vacuum exhaust. The vacuum exhaust system has the advantage of strong exhaust capacity; therefore, exhaust time is shortened after the system is adopted; and the system can obtain a vacuum degree required by vacuum die casting and finally improves the quality of vacuum die casts.
