Description

Vacuum preservation container

The invention relates to a vacuum preservation container which has the effect of automatically maintaining a good vacuum effect and is convenient for the user to operate.

According to the conventional food preservation container, the typical published patent examples include: US20070034628, US20070056971, US5964255, CN2853685, JP2010-236514 & TW554909, etc., because such prior art has such an inability to continuously and continuously seal, no automatic start-up inhalation mechanism And the operation is not true and many other defects, for example; the outer cover body and the seat body are connected to each other, and the suction pump is installed in the interior of the seat body, so the seat body cannot be effectively washed with water; The seat body is a one-to-one mating cover combination, so that the outer cover body cannot be independently connected to the seat body, and it exhibits a negative pressure state on any surface.

In view of the above-mentioned lack of the traditional food preserving device, the inventors have previously developed a vacuum preservative cover with automatic evacuation, and have obtained the patents of TW I322780, CN101412457 & US8,113,246, respectively.

Because the vacuum preservation cover is placed at the bottom of the main body, the one-way valve can not be completely closed, and the suction will remain after the action of the rubber suction pump, so that the film is incompletely sealed and the suction is presented. After vacuum, the one-way valve cannot be pressed by atmospheric pressure to achieve a snug fit, because most of the pressure will be rounded. It is obvious that there is indeed room for improvement and necessity for its vacuum preservation effect.

In order to overcome the above-mentioned lack of the traditional food storage box or the vacuum preservation container, the inventors have carefully developed the "vacuum preservation container" of the present invention, and its structure mainly consists of a storage tank, a connection socket, an air intake/intake mechanism and an upper cover.

The storage tank in the device of the present invention is a container in which the upper end of the tubular shape is open and can accommodate the opened food, the pasta, the biscuit, the candy, the mushroom, and the like.

The connecting socket in the device of the invention has a thread on the inner edge of the upper end tube, the thread is screwed with the suction/intake mechanism on the upper end, and a connecting cylinder is arranged in the center of the connecting socket, and the concave formed by the connecting barrel is formed. The center of the hole is provided with a squat-shaped air hole, and the outer periphery of the lower end of the connecting seat and the upper part are integrally formed with the soft plastic at the upper side, and the soft rubber at the lower end of the lower end is designed in multiple layers and the soft rubber is integrally formed toward the upper surface to be placed therein. The lower storage tank and the suction/intake mechanism screwed to the upper side exhibit a good airtight effect.

The air suction/intake mechanism in the device of the present invention is a circular groove box which is interposed between the connection socket and the upper cover, and has a battery holder facing downwardly, and is provided with a motor and a suction pump and pressure toward the upper surface. Inductive soft rubber, the pressure sensing soft rubber is in contact with a micro switch, and the pressure sensing soft rubber is topped by the air pressure in the container, and the micro switch power supply is turned on to start the motor to inhale, and when the air in the container is sucked out, the vacuum is in a vacuum state. When the pressure is increased, the pressure sensing soft gel is instantly sunk, and the micro switch power supply is blocked to stop the motor suction operation.

The pressure sensing soft rubber of the suction/intake device of the device is separately designed and made of different materials, and the pressure sensing soft rubber has the characteristics of instantaneous rising and instantaneous falling control, which makes it conduct and block the suction. Pump motor power control is more control flexibility.

The upper cover of the device of the present invention is disposed above the air intake/intake mechanism, and is provided with an intake and exhaust hole, and in particular, the exhaust hole is disposed with a push-type exhaust button for quickly and easily pushing open the air valve to block The power source is supplied with air, and the contents of the storage tank are taken or placed in the storage tank.

In general, the present invention mainly utilizes a special component in the air intake/intake mechanism and a control operating element on the upper cover to make it a vacuum preservation container with automatic vacuum preservation effect and user-friendly operation, which has overcome Traditional food crispers or vacuum storage containers have many advantages.
