detailed description

The preferred embodiments of the present utility model are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present utility model, and are not intended to limit the present utility model.

The easy-to-manipulate vacuum storage container, as shown in Figure 1 and Figure 2, includes a box body 1 and a vacuum control device 2 detachably installed on the box body 1, and the box body 1 is provided with a vacuum release valve 11, as shown in Figure 3 , the vacuum control device 2 is provided with a vacuum pump 24 (the specific structure is not shown). Specifically, as shown in Figures 2 and 7, the vacuum release valve 11 is a push-type vacuum release valve. When the vacuum release valve 11 is pressed, the vacuum release valve 11 will be displaced. Originally, the vacuum release valve 11 was blocked. The air inlet on the box body 1 is sealed, and when the vacuum release valve 11 is pressed and displaced, the vacuum release valve 11 will unseal the air inlet of the box body 1 and generate air intake. The channel allows outside air to enter the box body 1 . There is a through hole in the axial direction of the vacuum release valve 11, and the through hole is a vacuuming channel. A check valve 111 is arranged in the vacuuming channel. When the vacuum control device 2 is installed in the box body 1, it is connected to the vacuuming channel. The one-way valve 111 is opened when the vacuum pump 24 is pumping air. When the vacuum control device 2 is not installed or the vacuum pump 24 is not pumping air, the one-way valve 111 prevents air from entering the box body 1 . As shown in FIGS. 3 and 4 , the vacuum control device 2 is provided with a release valve control mechanism. When the vacuum control device 2 is installed in the box body 1 , the release valve control mechanism can open or close the vacuum release valve 11 . Specifically, the release valve control mechanism includes a jacking post 22 for pressing the vacuum release valve 11. The jacking post 22 can move in a controlled manner and press the vacuum release valve 11. The release valve control mechanism can be set as a line through the vacuum control device 2. Press the cylinder to transmit the pressing force to the vacuum release valve 11, so that the vacuum release valve 11 is deformed, and the vacuum state can be released. For the convenience of operation, as shown in Fig. 4, Fig. 5 and Fig. 6, the release valve control mechanism also includes a handle 21 for controlling the jacking column 22, the handle 21 is hinged to the vacuum control device 2, and one end of the jacking post 22 is jacked on the The handle 21 and the other end of the jacking post 22 are connected to the vacuum release valve 11 ; pulling the handle 21 can control the movement of the jacking post 22 to press the vacuum release valve 11 .

Specifically, in order to convert the rotational motion of the handle 21 into the linear motion of the top post 22, a drive structure 211 is provided between the handle 21 and the top post 22. The drive structure 211 can be arranged in a non-circular shape, and the handle 21 rotates When connecting and driving the jacking column 22 through the non-full circle part; or a gear structure can be set at the place where the handle 21 contacts the jacking column 22, and the above functions can also be achieved through gear transmission. A spring 221 is connected between the handle 21 and the top post 22, and the top post 22 is attached to the drive structure 211 through the spring 221, so that the top post 22 is also reset when the handle 21 is reset, preventing the top post 22 from pressing the vacuum release valve all the time 11; The spring can also be set between the top post 22 and the box body 1. When the top post 22 is not pressed down by the handle, the spring will push the top post 22 away from the vacuum release valve 11, which can also reach the above functions. Specifically, as shown in Figure 1, the vacuum control device 2 is provided with a groove matching the shape of the handle 21, and the handle 21 can be placed in the groove without driving the top post 22 to press the vacuum release valve 11, so that the overall appearance is beautiful. , and the user is not easy to touch the handle 21 by mistake.

When the user wants to release the vacuum state of the box body 1, the handle 21 is rotated (specifically rotated to 90° to the vacuum control device 2) so that the handle 21 presses the top post 22 downward, and the top post 22 will press the vacuum Release the valve 11, and the box body 1 intake air; and when the handle 21 is put back to the original position, the top connecting post 22 can be pulled up by the action of the spring 221, and the top connecting post 22 no longer presses the vacuum release valve 11, the box body 1 seal. And when the user takes away the vacuum control device 2, he can directly press the vacuum release valve 11 to make the box body 1 intake air.

In this embodiment, as shown in FIG. 7 , the release valve control mechanism is provided with a vacuum tube, which is the top post 22, and a through hole 222 is opened in the axial direction of the top post 22 to become a vacuum tube. , the through hole 222 is connected to the vacuum pump 24 through an air pipe (not shown in the figure). When the vacuum control device 2 is installed in the box body 1, the top connecting post 22 is in contact with the vacuum release valve 11, and the handle 21 is in a state of not being pulled. At this time, the vacuum release valve 11 is in the state of sealing the air inlet of the box body 1, and The through hole 222 of the top connecting column 22 is connected with the vacuuming channel of the vacuum release valve 11. When the vacuum pump 24 is started, the vacuum pump 24 pumps air to reduce the pressure of the through hole 222. The air pressure will be less than the air pressure in the box body 1. At this moment, the one-way valve 111 is opened, and the gas in the box body 1 is extracted, and the above-mentioned realization of the pumping of the box body 1 is carried out. In this embodiment, the vacuum release valve 11 cooperates with the top post 22, the vacuum release valve 11 can be used as a sealing part or as an air extraction hole, and the top post 22 can be used as a part for releasing the seal or as a vacuum tube, the two The combination of these two components realizes the functions of vacuuming and releasing the vacuum, killing two birds with one stone.

In this embodiment, the vacuum control device 2 is also provided with a control assembly, and when the release valve control mechanism opens the vacuum release valve 11, the control assembly stops the vacuum pump 24 from pumping. Specifically, as shown in Fig. 4 and Fig. 6, the control component is specifically a switch control structure 212 provided on the release valve control mechanism and a trigger switch 23 connected to the circuit of the vacuum pump 24 (related wires are not shown), the switch control structure The working principle of 212 is similar to that of the driving structure 211. When the release valve control mechanism opens the vacuum release valve 11 (that is, when the handle 21 rotates 90°), it will drive the switch control structure 212 to move together, so that the switch control structure 212 triggers the trigger switch 23 and disconnects the circuit of the vacuum pump 2 . The purpose of adding this control assembly is: when the user rotates the handle 21, that is, when the vacuum state is to be released, the vacuum pump 24 should be in a stopped state; and the control assembly is provided so that when the user rotates the handle 21, not only the pressing of the vacuum release is completed The action of valve 11 has also completed the action of disconnecting the circuit, without adding a new switch, killing two birds with one stone.

To sum up, the easy-to-control vacuum storage container of the present invention is easy to operate to release the vacuum state, and is convenient for users to use.

Finally, it should be noted that the above are only preferred embodiments of the utility model, and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the embodiments, for those skilled in the art, it is still The technical solutions recorded in the examples can be modified, or some of the technical features can be replaced equivalently, but within the spirit and principles of the utility model, any modifications, equivalent replacements, improvements, etc., should be included in the Within the protection scope of the present utility model.
