Description

Technical Field

[0001] The invention relates to the technical field of inflation joints, in particular to a soft two-way air valve. Background Art

[0002] Existing self-inflating products (such as air pillows, air cushions, etc.) are inflated and deflated through air valves during use. In the prior art, such air valves are usually simple open-close valves or one-way air valves. When inflating, open the air valve and wait for inflation or directly use an air pump to inflate. After the air is filled, close the air valve to seal; when deflated, open the air valve and squeeze the self-inflating product to expel the air inside, and then store it.

[0003] The main disadvantages of this type of valve are:

[0004] 1. When exhausting and storing, after squeezing out the air, you need to let go and close the air valve for sealing. In the process of letting go and closing the air valve, air will re-enter the product, resulting in low exhaust efficiency, incomplete exhaust, and increased storage volume.

[0005] 2. When inflating, after the air is fully inflated, the air pump needs to be removed and the air valve needs to be closed for sealing. In the process of removing the air pump but not closing the air valve in time, the gas filled in will be squeezed out by the internal positive pressure of the product, resulting in low inflation efficiency, unsaturated inflation and other problems;

[0006] 3. Self-inflating products equipped with one-way air valves can only ensure that one of the inflation or deflation processes is effective. If both the inflation and deflation processes need to be effective, two one-way air valves are required, which undoubtedly makes the operation complicated and causes trouble for users, and also increases the weight and size of self-inflating products. Summary of the invention

[0007] The purpose of the present invention is to provide a soft two-way air valve, which is formed by deformation of soft materials to solve the problem of two-way effectiveness of inflation and deflation of self-inflating products. In the inflation mode, the air valve only takes in air but does not exhaust air, and in the deflation mode, the air valve only exhausts air but does not take in air, thereby greatly improving the inflation and deflation efficiency of self-inflating products.

[0008] In view of the above problems, a technical solution adopted by the present invention is: to provide a soft bidirectional air valve, characterized in that it includes a first soft body made of a flexible material, the first soft body is provided with a plurality of channels, and the plurality of channels form a first concave surface and a second concave surface on the upper and lower surfaces of the first soft body respectively; a second soft body and a third soft body made of a flexible material and in a sheet shape are fixed on the upper and lower sides of the first soft body respectively, and a first protrusion and a second protrusion are arranged on the upper and lower surfaces of the first soft body respectively, and the first soft body has a first state and a second state of deformation under the action of an external force: when the first soft body is in the first state, the second soft body is fitted with the first concave surface, the second protrusion squeezes the third soft body, so that the third soft body is separated from the channel, and the gas can flow from bottom to top through the channel, and the flow of the gas from top to bottom is blocked by the second soft body; when the first soft body is in the second state, the third soft body is fitted with the second concave surface, the first protrusion squeezes the second soft body, so that the second soft body is separated from the channel, and the gas can flow from top to bottom through the channel, and the flow of the gas from bottom to top is blocked by the third soft body.

[0009] Furthermore, the first soft body includes a bowl-shaped soft body, the hole is arranged at the bottom of the bowl of the bowl-shaped soft body, the bowl-shaped soft body bulges upward to form the first state, and the bowl-shaped soft body is sunken downward to form the second state.

[0010] Furthermore, a circle of first thin-walled annular grooves is set at the bottom of the bowl of the bowl-shaped soft body, and a circle of second thin-walled annular grooves is set at the edge of the bowl of the bowl-shaped soft body. The deformation range of the bowl-shaped soft body is limited by the first thin-walled annular grooves and the second thin-walled annular grooves, thereby realizing switching between the first state and the second state.

[0011] Furthermore, the first thin-walled annular groove and the second thin-walled annular groove are respectively arranged on the upper and lower surfaces of the bowl-shaped soft body.

[0012] Furthermore, the first concave surface is connected to a handle, and the handle receives external force to achieve state switching of the bowl-shaped soft object.

[0013] Furthermore, the first protrusion and the second protrusion respectively include a plurality of strip-shaped protrusions evenly spaced and arranged on the upper and lower surfaces of the bowl wall of the bowl-shaped soft body.

[0014] Furthermore, the first concave surface and the second concave surface are both provided with smooth arcs, the second software body is provided with a smooth arc surface matching the first concave surface, and the third software body is provided with a smooth arc surface matching the second concave surface.

[0015] Furthermore, the size of the second soft body and the third soft body is larger than the first thin-walled annular groove.

[0016] The beneficial effects of the present invention are:

[0017] 1. Through the deformation of the soft material, the free switching of the forward and reverse two-way air valve is realized, so that the two-way effectiveness of inflation and exhaust of self-inflating products can be guaranteed through one air valve;

[0018] 2. In exhaust mode, only exhaust is done without taking in air, which improves the exhaust efficiency and reduces the storage volume;

[0019] 3. In the inflation mode, only air is taken in but not exhausted, which improves the inflation efficiency and inflation saturation;

[0020] 4. The reversing operation is simple;

[0021] 5. Small size and light weight. BRIEF DESCRIPTION OF THE DRAWINGS

This is merely for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0030] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] The embodiment of the present invention is a two-way air valve for inflating and deflating self-inflating products. The one-way air inlet valve and the one-way air outlet valve are switched by deformation of soft materials, so that the effectiveness of inflation and deflation can be ensured by one air valve at the same time, thereby improving the inflation and deflation efficiency and reducing the size and weight of the self-inflating products.

[0032] See also Figure 1 to Figure 3 The embodiment of the present invention is a soft bidirectional air valve, the main body of which is a bowl-shaped soft body 1 made of flexible material and in a bowl-shaped structure, and the upper and lower surfaces of the bowl-shaped body are respectively arranged with two circles of thin-walled annular grooves: the inner thin-walled annular groove 7 is arranged at a position close to the bottom of the bowl on the lower surface of the bowl-shaped soft body 1, and the outer thin-walled annular groove 8 is arranged at a position close to the edge of the bowl on the upper surface of the bowl-shaped soft body 1. The inner and outer thin-walled annular grooves are used to deform the bowl-shaped soft body 1 within a limited range to form a convex state and a concave state; the upper and lower surfaces of the bowl-shaped soft body 1 .... An upper sheet-like soft body 2 and a lower sheet-like soft body 3 made of flexible material are respectively fixed thereon, and the diameters of the upper sheet-like soft body 2 and the lower sheet-like soft body 3 are slightly larger than the inner thin-walled annular groove 7; a plurality of strip-like protrusions 5 are respectively provided on the upper and lower surfaces of the bowl-shaped soft body 1, and a plurality of holes 9 for ventilation are arranged at the center of the bottom of the bowl-shaped soft body 1, and the plurality of holes form an upper hole concave surface 4 and a lower hole concave surface with an arc on the upper and lower surfaces of the bowl-shaped soft body 1, wherein a columnar handle 6 is connected to the upper part of the upper hole concave surface 4.

[0033] When in use, the air valve is mounted on the self-inflating product through the bracket 11:

[0034] When the cylindrical handle 6 is pulled (see Figure 4 ), the bowl-shaped soft body 1 bulges upward, thereby deforming the upper sheet-like soft body 2 and fitting with the concave surface 4 of the upper channel, and the strip-like protrusions 5 on the lower surface of the bowl-shaped soft body 1 squeeze the lower sheet-like soft body 3, so that the lower sheet-like soft body 3 is separated from the concave surface of the lower channel, so that the gas can flow from bottom to top through the channel 9 (dashed line in the figure), and the flow of gas from top to bottom is blocked by the upper sheet-like soft body 2 (solid line in the figure), that is, a one-way air outlet valve is formed. After the air is released, the lid 10 can be covered to achieve sealing.

[0035] When the cylindrical handle 6 is pushed (see Figure 5), the bowl-shaped soft body 1 is sunken downward, so that the lower sheet-shaped soft body 2 is deformed and fits with the concave surface of the lower channel, and the strip-shaped protrusions 5 on the upper surface of the bowl-shaped soft body 1 squeeze the upper sheet-shaped soft body 2, so that the upper sheet-shaped soft body 2 is separated from the concave surface 4 of the upper channel, so that the gas can flow from top to bottom through the channel 9 (dashed line in the figure), and the flow of gas from bottom to top is blocked by the lower sheet-shaped soft body 3 (solid line in the figure), that is, a one-way air inlet valve is formed. After inflation is completed, the lid 10 can be covered to achieve sealing.

[0036] The innovation of the present invention lies in that the strip protrusions 5, the upper and lower sheet-like soft bodies and the upper and lower concave surfaces of the channel are changed and combined by the deformation of the bowl-shaped soft body 1, thereby forming a two-way air valve function that can be freely switched. There is no need to equip two one-way air valves for inflation and deflation operations. The structure is simple and the operation is convenient. It can improve the inflation and deflation efficiency of self-inflating products and also reduce their storage volume.

[0037] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
