A vacuum device for rice bags

Abstract

The invention discloses a vacuuming device for rice bags. The vacuuming device comprises an exhaust device and a vacuum orifice device matched with the exhaust device. The vacuuming device is installed in a ventilation opening of a rice bag, the vacuuming device comprises a vacuuming valve base and a vacuuming valve deck installed on the rice bag, the upper end of a exhaust cylinder shell is inserted into a connecting portion, a lifting hole is formed in the middle of a connecting base, the lifting structure is in sliding connection with the lifting hole, the lifting structure is composed of alifting structure body and a reset spring, the lifting body comprises a handle, a connecting rod and an airtight structure, the handle is transversely arranged at the upper end of the connecting rod,a non-woven fabric layer is arranged at the inner side wall of an elastic iron ring, the lower end of an exhaust cylinder suction nozzle is provided with an iron hoop groove matched with the elasticiron ring, and the bottom of the exhaust cylinder is connected with the vacuuming valve deck through a reinforcing structure. According to the vacuuming device for rice bags, the cover device is connected firmly, the service life is long, air leakage can be avoided, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of vacuuming, in particular to a vacuuming device for rice bags. Background technique [0002] At present, people use some easy-to-seal containers for the preservation of food preservation and moisture-proof and mildew-proof articles after the electric pump device vacuumizes, and then seals. Commonly used air pumps need to be used with both hands, which is very inconvenient. When the general air pump is pumping air, the direction of the handle will shift, resulting in low pumping efficiency, and the suction nozzle on the air pump is easy to deform after a long time of use. Air leakage affects the use. Usually, there is a vacuum valve on the bag body of the compression bag, and it is pumped with the pump. The method of use is to align the suction nozzle of the pump with the outlet of the vacuum valve. Air extraction is carried out, and there is usually no fixed anti-skid device between the two, which is easy...

Problems solved by technology

Commonly used air pumps need to be used with both hands, which is very inconvenient. When the general air pump is pumping air, the direction of the handle will shift, resulting in low pumping efficiency, and the suction nozzle on the air pump is easy to deform after a long time of use. Air leakage affects the use. Usually, there is a vacuum valve on the bag body of the compression bag, and it is pumped with the pump. The method of use is to align the suction nozzle of the pump with the outlet of the vacuum valve. Air extraction is performed, and there is usually no fixation between the two, and the anti-skid device is easy to slip and leak air during use, which affects efficiency
