Detailed Description

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. The utility model may be embodied in many other forms than described herein and similarly practiced by those skilled in the art without departing from the spirit or scope of the utility model, which is therefore not limited to the specific embodiments disclosed below.

Example 1

As shown in fig. 1 and 2, a handle with an anti-overflow micro-pressure valve is provided, one end of a handle body 1 is provided with a circular mounting groove 101, and the center of the mounting groove 101 is provided with a valve hole 102. The micro-pressure valve 2 is slidably connected in the valve hole 102, the micro-pressure valve 2 comprises an upper baffle 201, three connecting columns 202 and a lower baffle 203 which are sequentially connected from top to bottom, the outer diameters of the upper baffle 201 and the lower baffle 203 are larger than the inner diameter of the valve hole 102, the three connecting columns 202 are distributed in an equidistant annular mode, and the length of each connecting column 202 is larger than the depth of the valve hole 102.

The mounting groove 101 is internally provided with the convex ring 103 concentric with the valve hole 102, the bottom surface of the upper baffle 201 is an arc concave surface, and the outer diameter of the convex ring 103 is smaller than that of the upper baffle 201, so that the upper baffle 201 can be more tightly covered with the valve hole 102.
