The utility model discloses an aluminum foil vacuum bag and relates to the technical field of packaging bags, the aluminum foil vacuum bag comprises a bag body, an opening is formed in one side of the bag body in the length direction, a plurality of first vent grooves and second vent grooves are formed in the bag body in a protruding mode in the direction away from the interior of the bag body, the first vent grooves are formed in the length direction of the bag body, and the second vent grooves are formed in the length direction of the bag body. The multiple first vent grooves are arranged in the width direction of the bag body at equal intervals, the multiple second vent grooves are arranged in the width direction of the bag body at equal intervals, the multiple first vent grooves and the multiple second vent grooves are communicated with each other, and the first vent grooves and the second vent grooves are wavy. When the vacuum bag is vacuumized, the multiple first vent grooves and the multiple second vent grooves can form an air exhaust channel in the bag body, and therefore air in the bag body can be rapidly evacuated.

The utility model discloses a nasal spray device which comprises a shell, a supply unit and a force storage mechanism, the supply unit is used for storing and outputting second fluid, and in an initial state, the supply unit is locked at a first position in the shell; and the force storage mechanism is connected with the supply unit, and the force storage mechanism is manually operated in advance to apply loading force to the supply unit, so that after unlocking, the supply unit can be ejected to a second position in the shell and outputs second fluid. According to the nasal spray device, loading force is applied in advance through the force storage mechanism, and triggering force can be provided at the unlocking moment, so that the pump assembly is promoted to rapidly pump out medicine, and then the medicine is delivered to a farther position.

The utility model relates to vacuum sealing machine technical field especially simple type plastic packaging bag vacuum sealing device, its technical scheme: including shell, the shell bottom is fixed with bottom shell, the vacuum pump is installed in the bottom shell, the shell upper end front side is equipped with the sealing cavity, the sealing cavity bottom rear side is equipped with the air extraction hole, the sealing cavity bottom and located the air extraction hole peripheral fixed sealing pad, the sealing cavity bottom front side is fixed with the electric heating wire, the sealing cavity is hinged with the flap, is provided with same sealing pad in the sealing cavity in the flap. The utility model sets up the transverse plate that stretches out in the annular sealing pad of air extraction, when air extraction, utilizes the transverse plate and inserts into the packaging bag, can quickly extract the gas in the packaging bag through the flow guide hole, effectively avoids the packaging bag opening to be extruded by the sealing pad, leads to the problem that the gas is difficult to discharge outward, improves the vacuumizing efficiency.
