Problems solved by technology

In known vacuum suction devices no unit is proposed for effectively preventing the transfer of moisture to the vacuum pump
[0007] Also, known vacuum suction devices drive the piston via a crown gear and connecting rod, but this is not efficient in terms of noise or durability
Also, compact vacuum pumps may not be possible
Furthermore, in known vacuum suction devices it is not easy to store the vacuum suction device after use

Abstract

Provided is a handy type vacuum suction device compactly constructed including a suction nozzle for minimizing the flow of water into a vacuum pump to improve the durability of a pressure switch which measures a degree of vacuum, and a diaphragm type vacuum pump. The handy type vacuum suction device comprises an external case, a cap including the suction nozzle and detachably mounted at the lower end of the external case, a pressure switch part mounted in the external case and including the pressure switch for cutting off power supply with a sliding body to be moved down while overcoming the elastic force of a spring when pressure in the cap falls down to predetermined pressure or lower, and a suction pipe formed passing though the inside to the outside, the vacuum pump having a suction port connected to the suction pipe for sucking air in a diaphragm system, and a control part having an operating switch and electrically connected to the vacuum pump and the pressure switch for controlling the operation of the vacuum pump.

Description

Technical field [0001] The present invention relates to a hand-held vacuum suction device, and in particular, to a pressure switch that has a suction nozzle for minimizing moisture flowing into a vacuum pump and can improve a pressure switch for measuring the degree of vacuum. Durable hand-held vacuum suction device that simplifies the internal structure by using a diaphragm-type vacuum pump. Background technique [0002] If foods such as fruits, vegetables, meats, and foods are not kept sealed, they may deteriorate or quickly deteriorate due to oxygen in the air. Therefore, a vacuum container is used in which a vacuum state is maintained by discharging internal air to the outside. [0003] The vacuum container may include an exhaust unit for exhausting the internal air to the outside, but the vacuum container usually includes a check valve at one end for exhausting the internal air to the outside, and is sucked by using an additional vacuum. The device exhausts the internal air ...
