Detailed Description

The following will combine the drawings of the embodiments of the present invention to further describe the technical solution of the present invention, and the present invention is not limited to the following specific embodiments. It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.

As shown in fig. 1 to 5, a check valve for an extrusion container includes: a valve body 100 and a connecting body 200, wherein the outer side surface of the valve body 100 is provided with a circle of connecting blocks 110, the valve body 100 has a communicating chamber 140 therein, one end of the valve body 100 is opened with a communicating port 120, the other end is opened with a discharging port 130, the communication port 120 and the discharge port 130 are both communicated with the communication chamber 140, the connection body 200 is fixedly arranged in the communication chamber 140, one end of the connecting body 200 is provided with a first connecting port, the other end is provided with a second connecting port 220, and the connecting body 200 has a communication channel 210 therein, the first connection port and the second connection port 220 are both communicated with the communication channel 210, the side wall of the communicating channel 210 is rotatably provided with a connecting sheet 400, one end of the connecting sheet 400 is rotatably connected with the side wall of the communicating channel 210, the other end of the connecting sheet 400 is connected with a valve plate 300, and the valve plate 300 movably covers the discharge hole 130.

That is, the entire valve body 100 is fixedly connected to an external extrusion container, specifically, the discharge port 130 is close to the inside of the extrusion container, and the communication port 120 is close to the material port of the extrusion container, when a material body in the extrusion container is required to be used, the material body is extruded with a proper force, and at this time, the material body starts to flow out of the discharge port 130, then continues to flow out through the communication channel 210 after passing through the first communication port 120 and pushing the valve plate 300, flows out of the second connection port 220 to the communication port 120, and finally flows out of the material port of the extrusion container. After the use, the extrusion container is vertically placed, the material opening faces upwards, the bottle body is not extruded, the material body falls back into the bottle body, at the moment, the valve plate 300 automatically moves downwards due to the extrusion effect of the material body, and the valve plate 300 covers the material outlet 130 due to the gravity effect. That is, by using the check valve of the extrusion container, it is well prevented that air and the contaminated material remaining at the discharge port 130 are sucked into the container to contaminate the material therein when the container is decompressed and restored to its shape, thereby preventing the quality of the material from being affected and shortening the shelf life of the material.

In one embodiment, a snap ring 500 is further disposed on the outer side surface of the valve body 100, and the snap ring 500 is used for connecting with an external extrusion container.
