CN2863696Y - Vacuum fresh-keeping case capable of automatic detecting vacuum state - Google Patents

Abstract

The utility model relates to a vacuum fresh-keeping case capable of automatic detecting vacuum state, including an upper cover, a pedestal and a base, wherein the upper cover can do the opening action on the base having an exhaust valve to obtain the effect of staleness for the lower pressure. A vacuum-pumping module, a pressure sensing module, an outer power module, an assistant battery pack seat and a power switch button are arranged in the base, for controlling each module to operate using one control circuit, wherein the vacuum-pumping module and the pressure sensing module are connected to the tray on the base to use conveniently. The food is laid in the box, and the box is pumped in a vacuum state by the vacuum-pumping module and senses the given vacuum value in the box by the pressure inductor, which can turn off the power from the control circuit to the power switch by the automatic switch arranged therein, to stop the motor in the vacuum module, then the vacuum pumps stops pumping air to obtain the effect of automatic sensing vacuumizing, rather than causing the box damaged by the excess pumping.

Description

Vacuum crisper with Auto-Sensing vacuum state

Technical field

The utility model is meant a kind of vacuum crisper with Auto-Sensing vacuum state, be meant a kind of function that possesses Auto-Sensing box body inner vacuum value especially, can not bleed excessive and can vacuumize at any time to reach normal guarantor's box body inside remains on a kind of vacuum crisper with Auto-Sensing vacuum state under the vacuum state that perseverance establishes.

Background technology

Press, vacuum crisper is to be used for foodstuff storing, little article etc., for reaching fresh-keeping purpose, whether reach absolute vacuum values in its room, excellent is important, and general vacuum crisper, how only can be with manually with the air extraction in the room, and do not know whether room has reached level of vacuum, and be difficult to reach the effect of vacuum freshness retaining, though have the dealer to install to have the prompting dish of time, but still need manually to cut away source switch automatically, and whether room inside has reached level of vacuum still is difficult to determine, necessity of improvement is arranged in fact.

Moreover, existing demand can reach the crisper of automatic vacuum, automatic gas extraction device wherein, all be to be held on the micro-switch by a hollow rubber crown that is wrinkle shape, when being vacuum in the box body, be compressive state by this Rubber end and make switch closure, when having air to exist in the box body, then be stretched condition with self-opening bleed the group Pu, precisely because, the hollow rubber head that is wrinkle shape by this kind is done the effect of detecting vacuum values, find through the actual test of industry and after using, and can't reach good vacuum effectiveness, especially, behind the air in the user discharges box body, no matter what lose heart, as long as the power-on switch is bled after group's action of vacuumizing of Pu again, empty Rubber end is after the action of losing heart among this wrinkle shape, no matter what lose heart, the action that vacuumizes of all replying the stretched condition that is original state and carrying out repetition just stops to bleed action after being compressive state, this kind can't be detected the structure of the vacuum values in the box body, cause box body excessively to bleed easily and cause damage, the essentiality of improvement is arranged in fact.

Novel content
