As a further technical scheme of the utility model, the main ventilation holes are round, and the length of the main ventilation holes is the same as the sum of the lengths of the rubber plug and the rubber plug cap.

As a further technical scheme of the utility model, the plurality of auxiliary ventilation holes are all round, and the diameter of the plurality of auxiliary ventilation holes is smaller than that of the main ventilation hole.

As a further technical scheme of the utility model, the top of the rubber plug cap is provided with a plurality of protruding blocks, and the protruding blocks are distributed in a circular ring shape.

As a further technical scheme of the utility model, the length of the rubber plug is longer than that of the rubber plug cap.

As a further technical scheme of the utility model, the width of the groove is smaller than that of the rubber plug cap.

Compared with the prior art, the utility model has the beneficial effects that:

1. when the rubber plug is used, the storage appliance is sealed, when stored articles emit gas, the pressure in the storage appliance is gradually increased along with the accumulation of the gas, and after the pressure is increased to a certain degree, the gas can be discharged through the main ventilation holes and the auxiliary ventilation holes, so that the storage appliance is not damaged, and the service life of the rubber plug can be prolonged;

2. according to the utility model, the plurality of protruding blocks at the top of the rubber plug cap play a role in increasing friction force, so that the rubber plug cap is convenient for workers to use.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-4, in an embodiment of the present utility model, a rubber plug with an exhaust function includes a rubber plug cap 1, wherein an annular groove 6 is provided at the bottom of the rubber plug cap 1; the inner side of the groove 6 is provided with a rubber plug column 2, and the top of the rubber plug column 2 is fixedly connected with the bottom of the rubber plug cap 1;

a main ventilation hole 5 is arranged in the middle of the rubber plug column 2, and the main ventilation hole 5 penetrates through the rubber plug column 2 and the rubber plug cap 1; a plurality of auxiliary ventilation holes 4 are formed in the groove 6, and the auxiliary ventilation holes 4 penetrate through the rubber plug cap 1;

the main ventilation holes 5 are round, and the length of the main ventilation holes 5 is the same as the sum of the lengths of the rubber plug column 2 and the rubber plug cap 1;
