Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of inflation valves, in particular to an adjustable inflation valve. Background Art
[0002] An inflation valve is a valve used for inflating or deflation, and is commonly used in inflatable products such as swimming rings, air mattresses, and hovercrafts. The function of an inflation valve is to control the gas entering or exiting an inflatable product. When inflating, the inflation valve needs to be connected to an air source, such as an air pump or compressor, and then the air or gas is injected into the inflatable product through the inflation valve until the preset pressure or the required inflation volume is reached.
[0003] In order to ensure that inflatable products do not leak easily during use, some inflation valves use a one-way valve core, that is, when the gas flows in the direction of entering the inflatable product, the valve core is in an open state, and when the gas flows in the direction of exiting the inflatable product, the valve core is in a closed state. Although this design effectively solves the problem of leakage, when the inflatable product needs to be actively exhausted after use, the one-way valve often needs to be removed, which makes it more troublesome to use. Utility Model Content
[0004] The utility model aims to solve the problem that although the inflation valve in the prior art can effectively avoid air leakage, the one-way valve needs to be removed when active exhaust is required, which makes the use more troublesome.
[0005] To solve the above-mentioned problems, the utility model provides an adjustable inflation valve, including a valve housing, the valve housing is provided with a valve cavity and an inlet and an outlet respectively connected to the two sides of the valve cavity; it also includes a changing valve core rotatably connected to the valve cavity, the changing valve core is provided with a first air vent; the changing valve core is rotated to switch the head end of the first air vent to be connected to the inlet and the tail end to be connected to the outlet, or the head end of the first air vent is connected to the outlet and the tail end to the inlet; a limiting member is provided in the first air hole, and the limiting member is used to limit the first air hole to only one-way ventilation.
[0006] The above scheme is provided with a rotatable reversing valve core in the valve cavity, and a first vent hole is provided in the reversing valve core, and a limiting member is provided in the first vent hole to achieve only one-way ventilation, so that when inflation is required, it is only necessary to rotate the reversing valve core so that the one-way ventilation direction of the first vent hole is from the inlet to the outlet, at which time the external air source flows into the inflatable product from the inlet through the first vent hole and the outlet, and the gas in the inflatable product cannot flow out from the first vent hole; and when deflation is required, it is only necessary to rotate the reversing valve core so that the one-way ventilation direction of the first vent hole is from the outlet to the inlet, and the gas in the inflatable product can be quickly discharged. Compared with the prior art, the above scheme can be adapted to different inflation / deflation usage scenarios by rotating the reversing valve core, and the adjustment is simple and convenient, and the practicality is good.
[0007] Preferably, the direction-changing valve core is rotatably connected to the valve cavity via a rotating shaft, and the rotating shaft is located in the middle of the inlet and the outlet, so that the rotating shaft ensures that the direction-changing valve core rotates stably and reliably in the valve cavity.
[0008] Preferably, a second air vent is provided in the changing valve core, and the axes of the first air vent, the second air vent and the rotating shaft are perpendicular to each other. The changing valve core rotates around the axis of the rotating shaft to switch the two ends of the first air vent to be connected to the inlet and the outlet, or the two ends of the second air vent to be connected to the inlet and the outlet. Therefore, every time the changing valve core rotates 90 degrees around the rotating shaft, the connection state of the first air hole / the second air hole relative to the inlet and the outlet of the valve housing can be switched, which is convenient for user adjustment. Moreover, since there is no limiting part in the second air hole, when the two ends of the second air hole are connected to the inlet and the outlet, the air can be deflated faster.
[0009] Preferably, the outer surface of the changing valve core is spherical, and the inner surface of the valve cavity is spherical. The outer surface of the changing valve core slides against the inner surface of the valve cavity, thereby not only enabling the changing valve core to rotate more stably in the valve cavity, but also improving the sealing between the changing valve core and the valve cavity, thereby reducing the problem of gas flowing into the gap between the changing valve core and the valve cavity.
[0010] Preferably, the limiting member is a hemispherical sheet structure made of elastic material, and the outer peripheral side of the limiting member elastically abuts against the hole wall of the first air hole, so that when the gas flows through the convex surface of the limiting member, it can pass through between the limiting member and the hole wall of the first air hole, and when the air flow flows through the concave surface of the limiting member, it cannot pass through between the limiting member and the hole wall of the first air hole, thereby realizing the one-way ventilation function of the first air hole.
[0011] Preferably, the direction-changing valve core is provided with supporting ribs extending to both ends of the first vent hole, the supporting ribs and the outer surface of the direction-changing valve core are located on the same spherical surface, the middle part of the limiting member is connected to the supporting ribs at either end of the first vent hole, and the convex surface of the limiting member faces the supporting ribs. The supporting ribs not only facilitate the user to rotate and adjust the direction-changing valve core, but also the supporting ribs corresponding to the first vent hole can support and fix the limiting member, thereby ensuring the stability of the limiting member in the first vent hole.
[0012] Preferably, the outer surface of the supporting rib is provided with a concave-convex friction area, so as to facilitate the user to rotate the direction-changing valve core.
[0013] Preferably, the inner surface of the valve cavity is provided with a first sealing clamp ring arranged around the inlet and a second sealing clamp ring arranged around the outlet, and the first sealing clamp ring and the second sealing clamp ring are both slidably abutted against the outer surface of the changing valve core, thereby further improving the sealing between the valve cavity and the changing valve core through the first sealing clamp ring and the second sealing clamp ring.
[0014] Preferably, the positions of the direction-changing valve core corresponding to the two ends of the first vent hole have different colors or patterns, so as to facilitate the user to distinguish them.
[0015] Preferably, the inlet of the valve housing is detachably connected to a valve cover, so that the valve cover can be connected to the inlet of the valve housing after inflation is completed to avoid air leakage. BRIEF DESCRIPTION OF THE DRAWINGS

If the specific posture changes, the directional indication will also change accordingly.
[0026] See also Figure 1-Figure 7 An adjustable inflation valve provided in an embodiment of the utility model comprises a valve housing 1, wherein the valve housing 1 is provided with a valve cavity 11 and an inlet 12 and an outlet 13 respectively connected to both sides of the valve cavity 11; further comprising a direction-changing valve core 2 rotatably connected to the valve cavity 11, wherein a first air vent 21 is provided in the direction-changing valve core 2; the direction-changing valve core 2 is rotated to switch the first air vent 21 so that the head end is connected to the inlet 12 and the tail end is connected to the outlet 13, or the head end of the first air vent 21 is connected to the outlet 13 and the tail end is connected to the inlet 12; a direction-limiting member 3 is provided in the first air vent 21, and the direction-limiting member 3 is used to limit the first air vent 21 to only one-way ventilation.
[0027] The above scheme is provided with a rotatable reversing valve core 2 in the valve cavity 11, and a first vent hole 21 is provided in the reversing valve core 2, and a limiting member 3 is provided in the first vent hole 21 to achieve only one-way ventilation, so that when inflation is required, it is only necessary to rotate the reversing valve core 2 so that the one-way ventilation direction of the first vent hole 21 is from the inlet 12 to the outlet 13, at this time, the external air source flows into the inflatable product from the inlet 12 through the first vent hole 21 and the outlet 13, and the gas in the inflatable product cannot flow out from the first vent hole 21; and when deflation is required, it is only necessary to rotate the reversing valve core 2 so that the one-way ventilation direction of the first vent hole 21 is from the outlet 13 to the inlet 12, and the gas in the inflatable product can be quickly discharged. Compared with the prior art, the above scheme can be adapted to different inflation / deflation usage scenarios by rotating the reversing valve core 2, and the adjustment is simple and convenient, and the practicality is good.
[0028] To explain more clearly, Figure 4As a reference, in this embodiment, the inlet 12 is arranged at the upper part of the valve housing 1, and the outlet 13 is arranged at the lower part of the valve housing 1. The direction-changing valve core 2 is rotatably connected to the valve cavity 11 through the rotating shaft 4, and the rotating shaft 4 is located in the middle of the inlet 12 and the outlet 13, so that the rotation of the direction-changing valve core 2 in the valve cavity 11 is stable and reliable. More specifically, in this embodiment, the rotating shaft 4 is respectively connected to the middle of the left side and the middle of the right side of the direction-changing valve core 2, and the middle of the left side and the middle of the right side of the valve cavity 11 are provided with a socket for the rotating shaft 4 to be rotatably plugged, so that the deformable valve core rotates around the axis of the rotating shaft 4.
[0029] As an optimization of the above embodiment, a second air vent 22 is provided in the direction-changing valve core 2, and the axes of the first air vent 21, the second air vent 22 and the rotating shaft 4 are perpendicular to each other. The direction-changing valve core 2 rotates around the axis of the rotating shaft 4 to switch the two ends of the first air vent 21 to be connected to the inlet 12 and the outlet 13, or the two ends of the second air vent 22 to be connected to the inlet 12 and the outlet 13. Therefore, the connection state of the first air vent 21 / the second air vent 22 relative to the inlet 12 and the outlet 13 of the valve housing 1 can be switched every 90 degrees of rotation of the direction-changing valve core 2 around the rotating shaft 4, which is convenient for users to adjust. Moreover, since there is no limiting member 3 in the second air vent 22, when the two ends of the second air vent 22 are connected to the inlet 12 and the outlet 13, air can be released faster. In addition, Figure 4 As a reference, in this state, the axis of the first vent hole 21 is along the up-down direction, the axis of the second vent hole 22 is along the front-back direction, and the limiting piece is arranged at the lower end position of the first vent hole 21 .
[0030] As an improvement on the above embodiment, the outer surface of the changing valve core 2 is spherical, and the inner surface of the valve cavity 11 is spherical. The outer surface of the changing valve core 2 slides against the inner surface of the valve cavity 11, thereby not only enabling the changing valve core 2 to rotate more stably in the valve cavity 11, but also improving the sealing between the changing valve core 2 and the valve cavity 11, thereby reducing the problem of gas flowing into the gap between the changing valve core 2 and the valve cavity 11.
[0031] It should be understood that in other embodiments, the reversing valve core 2 can also be designed to be other shapes, such as cylindrical or square, as long as it is ensured that when the two ends of the first vent hole 21 are respectively connected to the inlet 12 and the outlet 13 of the valve housing 1, the gas will not flow into the gap between the reversing valve core 2 and the valve cavity 11 to cause leakage.
[0032] The limiting member 3 is a hemispherical sheet structure made of elastic material, and the outer peripheral side of the limiting member 3 elastically abuts against the hole wall of the first vent 21, so that when the gas flows through the convex surface of the limiting member 3, since the limiting member 3 has elastic deformation ability, the airflow can push the outer peripheral side of the limiting member 3 away from the hole wall of the first vent 21, and the airflow passes through the limiting member 3 at this time; when the airflow flows through the concave surface of the limiting member 3, since the airflow cannot push the outer peripheral side of the limiting member 3 away from the hole wall of the first vent 21, the airflow cannot pass between the limiting member 3 and the hole wall of the first vent 21, that is, the one-way ventilation function of the first vent 21 is realized. Figure 4 In this state, the limiting member 3 has a convex surface facing downward and a concave surface facing upward.
[0033] Furthermore, the direction-changing valve core 2 is provided with support ribs 24 extending to both ends of the first vent hole 21 and both ends of the second vent hole 22, and the support ribs 24 and the outer surface of the direction-changing valve core 2 are located on the same spherical surface. The middle part of the limiting member 3 is connected to the support rib 24 at the lower end of the first vent hole 21 by a fixing pin 25, and the convex surface of the limiting member 3 faces the support rib 24; the support rib 24 is not only convenient for the user to rotate and adjust the direction-changing valve core 2, but also the support rib 24 corresponding to the first vent hole 21 can support and fix the limiting member 3, ensuring the stability of the limiting member 3 in the first vent hole 21. The support rib 24 can be a straight line shape or a cross shape that can play a better supporting role.
[0034] Furthermore, the outer surface of the supporting rib 24 is provided with a concave-convex friction area 241 , so as to facilitate the user to rotate the direction-changing valve core 2 .
[0035] In a preferred embodiment, the inner surface of the valve cavity 11 is provided with a first sealing clamp ring 14 arranged around the inlet 12 and a second sealing clamp ring 15 arranged around the outlet 13. The first sealing clamp ring 14 and the second sealing clamp ring 15 are both slidably abutted against the outer surface of the changing valve core 2, thereby further improving the sealing between the valve cavity 11 and the changing valve core 2 through the first sealing clamp ring 14 and the second sealing clamp ring 15.
[0036] In a preferred embodiment, the positions of the direction-changing valve core 2 corresponding to the two ends of the first vent hole 21 have different colors or patterns, so as to facilitate the user to distinguish them.
[0037] As an extension of the above embodiment, the inlet 12 of the valve housing 1 is detachably connected to the valve cover 5, so that the valve cover 5 can be connected to the inlet 12 of the valve housing 1 after inflation is completed to avoid air leakage. The detachable connection between the screw cover and the inlet 12 of the valve housing 1 can be a screw connection or an interference fit clamping connection, which is not limited in this design.
[0038] Although the disclosure is as above, the protection scope of the disclosure is not limited thereto. For those skilled in the art, various changes and modifications can be made without departing from the spirit and scope of the disclosure, and these changes and modifications will fall within the protection scope of the utility model.
