Detailed Description

In the description of the present invention, it is to be understood that the terms "front", "back", "inside", "outside", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention. The term "plurality" means more than two (including two).

For the understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention, but refer to fig. 1 to 11.

Example 1

As shown in fig. 1 to 4, the present embodiment provides an actively closed check valve, which includes a valve body 1 having a hollow structure, an exhaust end of the valve body 1 is provided with an end plate 2 and an elastic cap 3 covering the end plate 2, an outer end surface of the end plate 2 is provided with a protrusion 2a, vent holes 2b are distributed around the protrusion 2a, the elastic cap 3 is provided with exhaust holes 3a corresponding to the protrusion 2a, the elastic cap 3 is pressed on the protrusion 2a and blocks the exhaust holes 3a through the protrusion 2a, and the elastic cap 3 can deform outwards under the pressure of the outward exhaust airflow of the check valve to be away from the protrusion 2a, so as to open the exhaust holes 3a.

In a normal state, the elastic cap 3 is tightly pressed on the convex part 2a, the exhaust hole 3a is in a closed state to prevent air from entering, and during exhaust, air flow flowing from the rear end of the valve body 1 to the direction of the exhaust hole 3a flows to the elastic cap 3 through the exhaust hole 2b to extrude the inner end surface of the elastic cap 3 to be outwards deformed to be far away from the convex part 2a, so that the exhaust hole 3a is opened to exhaust air, and a one-way ventilation function is realized. The check valve is simple in structure, easy to achieve, low in failure rate and good in durability. It is worth mentioning that, because the elastic cap 3 generates pressing force on the convex part 2a and the periphery of the elastic cap 3 is fixed, the airflow in the valve body 1 can be rushed open to flow out of the exhaust hole 3a only when the airflow reaches a certain pressure, so that the airflow can be accumulated and stored in the valve body 1, and the finally ejected airflow of the one-way valve is more concentrated and the flow rate is faster. Moreover, since the periphery of the elastic cap 3 is fixed, vibration can be reduced during exhaust, thereby reducing noise.

Note that the end plate 2 is fixed in position, and the boss 2a may be made of a hard material. The projection surface of the exhaust hole 3a on the end plate 2 is not overlapped with the vent hole 2b, so that the exhaust hole 3a and the vent hole 2b can be prevented from being communicated in a normal state, and the air leakage phenomenon is reduced.

The area of the exhaust hole 3a can be smaller than half of the area of the end face of the elastic cap 3, so that external air can better generate pressure on the outer end face of the elastic cap 3, and meanwhile, the air quantity entering the exhaust hole 3a can be smaller than the air quantity distributed on the outer end face of the elastic cap 3, so that even if air enters the exhaust hole 3a from the outside of the valve body 1, the air cannot burst the elastic cap 3 to enter the one-way valve.

In the present embodiment, the protruding portion 2a gradually becomes thicker from front to back, and the diameter of the thicker end is larger than the inner diameter of the exhaust hole 3a, and the diameter of the thinner end is smaller than the inner diameter of the exhaust hole 3a. Wherein the shape of the convex portion 2a may be a hemisphere or a cone. Under the normality, the inner end edge of exhaust hole 3a compresses tightly on bellying 2a, and when it need outwards exhaust, inside air current forms the extrusion to the interior terminal surface of elasticity cap 3 and makes it outwards warp and keep away from bellying 2a, and the surface that slopes gradually on the bellying 2a can play certain guide effect simultaneously, lets the air current assemble to the junction of elasticity cap 3 and bellying 2a to more break through the hindrance easily, outwards discharge, reach the purpose that promotes exhaust efficiency. On the other hand, when the external air flow extrudes toward the elastic cap 3, because the gradually inclined surface on the convex part 2a supports against the inner end edge of the exhaust hole 3a, under the pressure of the external air flow, the inner end surface of the elastic cap 3 also gradually supports against the surface of the convex part 2a, and the exhaust hole 3a cannot be opened to allow the external air flow to flow into the valve body 1, thereby achieving the purpose of improving the one-way ventilation effect.

In the present embodiment, a gap is left between the outer end surface of the end plate 2 and the inner end surface of the elastic cap 3. Compared with the situation that the inner end face of the elastic cap 3 is extruded only by the air flow at the vent hole 2b, a gap is reserved between the outer end face of the end plate 2 and the inner end face of the elastic cap 3 provided with the exhaust hole 3a, so that the internal air flow is uniformly distributed between the inner end face of the elastic cap 3 and the outer end face of the end plate 2, the whole end face of the elastic cap 3 can be extruded, the outward deformation of the elastic cap is better pushed, and the exhaust effect is better.

In the present embodiment, an exhaust pipe 3b is connected to an outer end of the exhaust hole 3a. The exhaust pipe 3b can play a certain role in blocking external air flow, air entering the exhaust hole 3a from the outside is reduced, and the phenomenon that air is squeezed into the valve body 1 from the connection position of the elastic cap 3 and the boss 2a due to overlarge air pressure is avoided, moreover, the outer side wall of the exhaust pipe 3b can be under the pressure effect of the external air flow together with the outer end face of the elastic cap 3, so that the exhaust pipe is more stably pressed on the boss 2a, and the sealing effect is better.

With above-mentioned sole 9 use to shoes in, can realize the inside taking a breath of the shoes body, keep dry in the shoes, eliminate bacterial growing and reproduction condition, make the wearer feel ventilated and ventilative, the comfort is strong, and make the foot be difficult for receiving the bacterial infection.

In order to make the air from the air outlet pipe 6 enter the shoe better, an air outlet slot hole 13 is arranged on the upper surface of the front palm part far away from the air bag 4, and an air transmission channel 14 is arranged in the sole 9 and used for communicating the air outlet slot hole 13 with the air outlet pipe 6. Through setting up air outlet slot hole 13 can also let the gas that blows out directly carry out the blow drying to the sole region before the foot, reduce the interior humidity of shoes that leads to because of the foot perspires. The air outlet slots 13 can be strip-shaped grooves, the number of the air outlet slots 13 is multiple, the air outlet slots are distributed on the upper surface of the front palm part at intervals, and the air outlet slots 13 are communicated with each other, so that air from the air outlet pipe 6 can enter the shoe more dispersedly through the strip-shaped grooves, and all areas in the shoe can be kept dry as far as possible.
