Title:
SMART VACUUM FRESH-KEEPING MEAL-BOX
Document Type and Number:
WIPO Patent Application WO/2017/148356
Kind Code:
A1
Abstract:
A vacuum fresh-keeping meal-box comprises a meal-box body (1), a cover (8), an air suction and deflation structure, and a control module. The air suction and deflation structure and the control module are disposed in the cover (8). The cover (8) is detachably connected to the meal-box body (1). The air suction and deflation structure comprises a solenoid valve A (2), a solenoid valve B(6), an air pump (3), a three-way pipe C(7), and a three-way pipe D (4). The solenoid valve A (2) is connected to a branch pipe of the three-way pipe C (7), the solenoid valve A (2) is connected to the air pump (3), the air pump (3) is connected to a branch pipe of the three-way pipe D (4), another branch pipe of the three-way pipe C (7) is connected to the solenoid valve B (6), the solenoid valve B (6) is connected to the another branch pipe of the three-way pipe D (4), a main pipe of the three-way pipe D (4) is fixed on an outer side (5) of the cover, and a main pipe of the three-way pipe C (7) communicates with the meal-box body (1). The control module controls the air suction and deflation structure. According to the vacuum fresh-keeping meal-box, air is sucked from the fresh-keeping meal-box by means of the air pump, so that the air leakage rate is greatly reduced, the vacuum degree is high, the fresh-keeping time is long, and the fresh-keeping effect is good.
