Description
Technical Field
The utility model relates to the technical field of shoemaking accessories, in particular to a novel unidirectional ventilation structure.
Background
The air-permeable shoes utilize the inertial action of walking of human body, the heels are stepped on the air supply air bags arranged below the insoles, the air pushed out of the air bags is conveyed into the shoes along the air pipelines, and the polluted air generated under the feet is purified. When the heel is lifted, the compressed air supply air bag sucks back fresh air which is directly communicated with the outside of the shoe due to the negative pressure phenomenon; the fresh air is continuously output into the shoes by the air supply air bags which are pressed up and down by feet, so that fresh and environment-friendly wearing environment is provided, and the breathable shoes are popular at present.
The one-way valve is a device which can only flow in along the inlet and can not flow back the outlet medium, and is commonly called as a one-way valve, which is also called as a check valve or a check valve. The scheme disclosed in the Chinese patent document (patent number 201620848620.5) is as follows: the first split body, the second split body and the valve core ball; the first split body and the second split body are hollow cylinders; the first split body is internally provided with a first cylinder cavity for accommodating one end opening of the second split body and a first air hole communicated with the first cylinder cavity; the aperture of the first air hole is smaller than the valve core ball; the inner wall of the first split body is provided with a concave part; the second split body is provided with a second air hole and a third air hole at the other end opposite to the opening end of the second cavity; and an isolating column with one end fixedly connected with the second split body is arranged between the two split bodies; one end of the valve core ball is aligned with the first air hole, and the other end of the valve core ball is aligned with the isolation column. The technical point of the scheme is that the valve core ball blocks the air flow to enter the first air hole, so that the unidirectional conduction of the air flow is realized.
However, the check valve provided by the scheme is complex in structure and comprises the first split, the second split and the valve core ball, the processing parts are more, the valve core ball is required to be placed into the first split during assembly, the second split is embedded and installed into the first split, or the valve core ball is required to be placed into the second split, and the second split and the valve core ball are embedded and installed into the first split, so that the check valve is troublesome to assemble, and if the valve core ball falls carelessly in the assembly process and is not found or is not assembled, the check valve loses the effect of unidirectional conduction, and the occurrence of defective products is easy to cause.
Disclosure of utility model
The utility model overcomes the defects in the prior art, and provides the novel unidirectional ventilation structure which is simple in structure, convenient to assemble and good in unidirectional conduction effect.
In order to solve the technical problems, the utility model is realized by the following technical scheme:
A novel unidirectional ventilation structure, comprising a bearing piece, wherein the bearing piece is a sole or a fitting for being installed on the sole; the bearing piece is connected with a sealing piece, and is provided with an exhaust hole which is not lower than one; the seal comprises a sheet made of a high-elasticity material, the sheet is concave, one side of the concave of the sheet faces the exhaust holes, and the sheet completely covers all the exhaust holes.
Further, the bearing piece is provided with connecting holes, and the exhaust holes are distributed around the connecting holes; the sealing element comprises a connecting rod, one end of the connecting rod is connected with the sheet, the other end of the connecting rod is provided with at least one plug, and the plug is inserted and fixed in the connecting hole.
Further, the inner side surface of the sheet is provided with a seal ring not lower than one.
Compared with the prior art, the utility model has the beneficial effects that:
Because the sheet is made of high-elasticity materials, especially silica gel, the sheet has better softness and fitting degree, and one side of the sheet, which is concave, faces the exhaust hole; so that the seal fits over the vent when the seal is attached to the carrier; at this time, when the gas is discharged from one side of the carrier through the gas discharge hole, the gas may rush away the sheet, thereby being discharged; when the exhaust holes stop exhausting gas, the sheet material can be reset and re-attached to the exhaust holes, so that the external gas is prevented from entering the bearing piece, and the unidirectional ventilation effect is achieved; in addition, the sheet is provided with a sealing ring, so that the sealing effect of the sheet and the bearing piece can be further enhanced.
Drawings
The accompanying drawings are included to provide a further understanding of the utility model, and are incorporated in and constitute a part of this specification, in which:
FIG. 1 is a schematic illustration of a one-way ventilation structure of a ventilated footwear;
Fig. 2 is a schematic view of the inside surface of the seal.
In the figure: 1. a carrier; 101. an exhaust hole; 102. a connection hole; 2. a seal; 201. a sheet; 202. a connecting rod; 203. a plug; 204. and (3) a sealing ring.
Detailed Description
The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings, it being understood that the preferred embodiments described herein are for illustration and explanation of the present utility model only, and are not intended to limit the present utility model.
As shown in fig. 1 to 2, a novel unidirectional ventilation structure comprises a carrier 1, wherein the carrier 1 is a sole or a fitting for being mounted on the sole; in this embodiment, the carrier 1 is a sole; the bearing piece 1 is connected with the sealing piece 2, and the sealing piece 2 is connected to the bearing piece 1, so that the bearing piece 1 has a unidirectional exhaust function; the carrier 1 is provided with no lower than one exhaust hole 101; the sealing member 2 comprises a sheet 201 made of a high-elasticity material, preferably silica gel, with good softness and fit; the concave side of the sheet 201 faces the exhaust holes 101, and the sheet 201 completely covers all the exhaust holes 101.
