The utility model discloses a filter sound -absorbing structure is used to compressor air intake, including front cover, back cover, filter component, the front cover is fixedly connected with back cover and forms the internal cavity, be equipped with a plurality of baffle and sound -absorbing cotton in the internal cavity, the filter component is provided with air inlet and air outlet, the upper portion of front cover sets up the installation cavity, the installation cavity can dismantle and install filter component, the bottom of back cover sets up the air outlet, the length of baffle is less than the length of internal cavity, a plurality of baffles are mutually staggered arrangement, and the airflow channel is formed between mutually staggered arrangement baffle. The utility model integrates filter and sound -absorbing function in the same structure, replaces traditional discrete scheme, before compressor air intake, through the utility model can play the double -deck effect of filter and sound -absorbing, reduces equipment occupied space simultaneously, reduces installation layout difficulty, simplifies installation and maintenance process, and then reduces comprehensive cost.

The utility model discloses an air quality monitor, including the case, the both sides of its upper end are equipped with a plurality of air outlet, is equipped with the heat dissipation fan in the air outlet, the lower end bottom of case is equipped with a plurality of air intake mechanism for leading in air, and the air intake mechanism includes ventilation unit, and it includes the fixed seat in the case, still includes the ventilation pipe of horizontal rotatable installation on the fixed seat, the ventilation pipe penetrates the case and extends, and its extension end is equipped with a plurality of central symmetry distribution's connecting column, and the outside of a plurality of connecting columns is covered with the moistureproof screen of cylinder, and the bottom of a plurality of connecting columns is equipped with the base, drive unit, it sets up in the case, and with ventilation pipe transmission connection, is used for driving ventilation pipe horizontal rotation, cleaning unit, it has a plurality of, and the outside of ventilation pipe extension end is centrally symmetric and sets up, is used for cleaning the moistureproof screen surface. Such design air inlet is not easy to block, and has the function of moistureproof, and therefore equipment whole service life is longer.

The present application relates to the technical field of metal casting, and particularly discloses a core making machine, which is provided with at least two regulating systems in the circumferential direction of the side wall of a core box. During sand shooting, the exhaust adjusting branch of the regulating system controls the exhaust amount during sand shooting to avoid excessive pressure drop loss, and the negative pressure adjusting branch adjusts the vacuum degree in the cavity to increase the pressure difference between the region and other regions, improve the flowability of the sand, and facilitate compacting of the sand, thereby achieving good core making effect. During solidification and blowing, the blowing mechanism can blow triethylamine gas into the cavity through the top and side of the core box, achieve the best solidification and air intake combination, increase the air intake area, shorten the solidification time, improve the solidification efficiency, and increase the opening of the exhaust adjusting branch to increase the exhaust amount of the corresponding region and ensure smooth air intake. The present application also provides a sand shooting and solidification process control method applied to the core making machine.

The utility model discloses a decoration dust adsorption and purification integrated equipment, include: the car body, the top of car body is provided with the casing, and the left side inside of casing is provided with dust removal bucket, the right side inside of casing is provided with dust removal cloth bag, and the below of dust removal cloth bag is installed with fan, the top of left and right sides of casing all is provided with the gear ring, and the middle part of left and right sides of casing all is provided with the buckle, the outside of gear ring is connected with the handle, and the inside of gear ring is provided with the gear, and the inside of gear is connected with the pressing plate, the wind cylinder is fixedly connected with the left cover plate at the bottom, and the top outside of wind cylinder is connected with the suction tube, and the top of wind cylinder is connected with the air pipe. This decoration dust adsorption and purification integrated equipment, convenient for adsorption and subsidence to dust, convenient dust purification, still can carry out secondary filtration to dust, convenient fan operation, also convenient dust cleaning.

The utility model relates to an aerosol generating device, which comprises a heating tube, a heating tube, a heating element and an aerosol generating element, wherein a heating cavity is formed in the heating tube in a penetrating manner; and the base is matched at one end of the heating tube, and an accommodating cavity and an air inlet channel communicated with the accommodating cavity are formed in the base. The heating cavity and the containing cavity are communicated to form a containing channel used for containing at least part of the aerosol generating product, and at least one boss is formed at the end, close to the air inlet channel, of the containing cavity and used for supporting the aerosol generating product. The aerosol generating product is supported by the boss, and the contact area between the base and the bottom of the aerosol generating product can be reduced, so that the air inlet area is increased, the suction resistance is reduced, and the smoke outlet effect is improved.
