Description

Technical Field

[0001] This utility model belongs to the field of oxygen control valve technology, specifically, it relates to an oxygen control valve structure. Background Technology

[0002] An oxygen valve is a valve device specifically designed to control the flow of oxygen, and it is widely used in physical and chemical experiments, industrial production, medical fields, and other areas.

[0003] Existing oxygen valves have multi-path flow functions, typically manifested as three-way valves. One-way valves are used to connect to the main oxygen pipe, while two-way and three-way valves are used to supply oxygen to external systems. The two-way and three-way valves can be closed or opened independently. The main structure for achieving this function is a knob. However, the knobs on existing oxygen valves are small, making it difficult for users to rotate them for switching. Therefore, an oxygen control valve structure is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an oxygen control valve structure that can overcome or at least partially solve the above problems.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: an oxygen control valve structure, comprising: a valve ring respectively provided with an inlet pipe, a first outlet pipe, and a second outlet pipe; a mounting cavity disposed in the middle of the valve ring; a ring cover provided with a fixing block, the ring cover being rotatably installed in the mounting cavity; an arc-shaped pipe groove formed on the outer periphery of the ring cover, the first port and the second port on the arc-shaped pipe groove corresponding to the first outlet pipe and the second outlet pipe, respectively; a button plate fixedly connected to the fixing block; and a connecting plate disposed in the arc-shaped pipe groove, the connecting plate having a plurality of first dispersion holes for dispersing the gas passing through the arc-shaped pipe groove.

[0006] Preferably, the first and second air outlet pipes are horizontal, and the air inlet pipe is perpendicular to the first and second air outlet pipes.

[0007] Furthermore, the button plate includes a long plate, which is fixedly connected to the fixing block. Both ends of the long plate extend toward the inner wall of the ring cover. The long plate is provided with a protrusion facing away from the fixing block, and a transition portion is provided between the protrusion and the long plate.

[0008] Furthermore, three connecting plates are provided. When the first port and the second port are respectively opposite to the first air outlet pipe and the second air outlet pipe, the three connecting plates are respectively located between the first air outlet pipe and the air inlet pipe, at the opposite position of the air inlet pipe, and between the air inlet pipe and the second air outlet pipe.

[0009] Preferably, multiple blocking blocks are circumferentially fixedly connected to both sides of the valve ring, with one end of each blocking block extending toward the center of the valve ring to limit the position of the ring cover.

[0010] Preferably, both the first and second air outlet pipes are rotatably connected to a rotating shaft, and multiple baffles are fixedly connected to the circumference of the rotating shaft. One end of the rotating shaft extends outward, and a rod is fixedly connected to the rotating shaft.

[0011] Preferably, a transparent cover is fixedly connected to both the first and second air outlet pipes, and the rod is located inside the transparent cover.

[0012] Furthermore, six baffles are provided, three of which have second dispersion holes.

[0013] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: the ring cover in the present invention occupies a large proportion of the device and the button plate is long, so the user can easily adjust the opening and closing of the first air outlet pipe and the second air outlet pipe during adjustment.

[0014] In addition, the connecting plate set in the arc-shaped tube can disperse the oxygen passing through the arc-shaped tube. After the oxygen is dispersed, the oxygen and air are mixed more evenly, thereby improving the utilization rate of oxygen and making the oxygen inhalation effect better. Secondly, the dispersed oxygen flows more gently, reducing the discomfort of oxygen directly impacting the nasal cavity or respiratory tract, and improving the comfort of the oxygen inhalation experience.

[0015] When oxygen impacts the baffle, it drives the shaft to rotate. The rotating shaft then drives the lever to rotate, and the rotating lever indicates whether there is gas flow in the first or second outlet pipe. This also indirectly helps to indicate whether the ring cover rotation angle is correct, making it easier to adjust the ring cover.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0026] Example 1: Refer to Figures 1-6 An oxygen control valve structure includes: a valve ring 1 with an inlet pipe 13, a first outlet pipe 14, and a second outlet pipe 15 respectively; a mounting cavity 11 located in the middle of the valve ring 1; a ring cover 2 with a fixing block 21, the ring cover 2 being rotatably mounted in the mounting cavity 11 (it should be understood that a sealing gasket is provided on the outer periphery of the ring cover 2 or the inner wall of the valve ring 1 to further reduce the gap between the ring cover 2 and the valve ring 1, and to further prevent air leakage); an arc-shaped pipe groove 22, formed on the outer periphery of the ring cover 2, the first port 221 and the second port 222 of the arc-shaped pipe groove 22 corresponding to the first outlet pipe 14 and the second outlet pipe 15 respectively; a button plate 23 fixedly connected to the fixing block 21; and a connecting plate 24, set in the arc-shaped pipe groove 22, the connecting plate 24 having a plurality of first dispersion holes 241 for dispersing the gas passing through the arc-shaped pipe groove 22;

[0027] The first air outlet pipe 14 and the second air outlet pipe 15 are horizontal, and the air inlet pipe 13 is perpendicular to the first air outlet pipe 14 and the second air outlet pipe 15. This arrangement makes it easier for the user to rotate the knob plate 23 to drive the ring cover 2 to rotate in the valve ring 1, so as to control the opening and closing of the first air outlet pipe 14 and the second air outlet pipe 15.

[0028] The button plate 23 includes a long plate 231, which is fixedly connected to the fixing block 21. Both ends of the long plate 231 extend toward the inner wall of the ring cover 2. A protrusion 232 is provided on the long plate 231, which faces away from the fixing block 21. A transition portion 233 is provided between the protrusion 232 and the long plate 231.

[0029] Multiple blocking blocks 12 are circumferentially fixedly connected to both sides of the valve ring 1. One end of the blocking block 12 extends toward the center of the valve ring 1 to limit the ring cover 2.

[0030] When this device is in use, the main oxygen pipe is connected to the inlet pipe 13, and the first outlet pipe 14 and the second outlet pipe 15 are connected to the oxygen auxiliary pipes.

[0031] When the first port 221 and the second port 222 on the arc-shaped tube 22 are opposite to the first outlet pipe 14 and the second outlet pipe 15 respectively, the oxygen in the inlet pipe 13 will be connected with the first outlet pipe 14 and the second outlet pipe 15, so that oxygen is discharged from both the first outlet pipe 14 and the second outlet pipe 15.

[0032] At this time, the button plate 23 is horizontal with the air inlet pipe 13, which is used to clearly indicate that the first air outlet pipe 14 and the second air outlet pipe 15 are in a connected state.

[0033] When it is only necessary to connect the first outlet pipe 14 with the inlet pipe 13, simply rotate the ring cover 2 on the valve ring 1 by rotating the button plate 23, so that the second port 222 moves closer to the inlet pipe 13. At this time, the second outlet pipe 15 is in the closed state.

[0034] When it is only necessary to connect the second outlet pipe 15 with the inlet pipe 13, it is only necessary to rotate the ring cover 2 on the valve ring by rotating the button plate 23, so that the first port 221 moves closer to the inlet pipe 13. At this time, the first outlet pipe 14 is in the closed state.

[0035] The ring cover 2 occupies a large proportion of the device, and the button plate 23 is long, so the user can easily adjust the opening and closing of the first air outlet pipe 14 and the second air outlet pipe 15 during adjustment.

[0036] In addition, the connecting plate 24 set in the arc-shaped tube groove 22 can disperse the oxygen passing through the arc-shaped tube groove 22. After the oxygen is dispersed, the oxygen and air are mixed more evenly, thereby improving the utilization rate of oxygen and making the oxygen inhalation effect better. Secondly, the dispersed oxygen flows more gently, reducing the discomfort of oxygen directly impacting the nasal cavity or respiratory tract and improving the comfort of the oxygen inhalation experience.

[0037] Example 2: Refer to Figure 4An oxygen control valve structure is basically the same as that in Embodiment 1, but with the following additional feature: three connecting plates 24 are provided. When the first port 221 and the second port 222 are respectively opposite to the first outlet pipe 14 and the second outlet pipe 15, the three connecting plates 24 are respectively located between the first outlet pipe 14 and the inlet pipe 13, at the opposite position of the inlet pipe 13, and between the inlet pipe 13 and the second outlet pipe 15.

[0038] This means that regardless of whether the first outlet pipe 14 or the second outlet pipe 15 is open or closed, oxygen must first pass through the first dispersion hole 241 of the connecting plate 24.

[0039] Secondly, when both the first outlet pipe 14 and the second outlet pipe 15 are in the open state, the connecting plate 24, which is opposite to the inlet pipe 13, can also guide and divert the oxygen entering the arc-shaped pipe groove 22.

[0040] Example 3: Reference Figure 6 An oxygen control valve structure is basically the same as that in Embodiment 2, but further: a rotating shaft 3 is rotatably connected to both the first outlet pipe 14 and the second outlet pipe 15. Multiple baffles 31 are fixedly connected to the circumference of the rotating shaft 3. One end of the rotating shaft 3 extends outward, and a rod 34 is fixedly connected to the rotating shaft 3.

[0041] A transparent cover 33 is fixedly connected to both the first air outlet pipe 14 and the second air outlet pipe 15, and the rod 34 is located in the transparent cover 33.

[0042] When oxygen impacts the baffle 31, it drives the rotating shaft 3 to rotate. The rotating shaft 3 drives the rod 34 to rotate. The rotating rod 34 can be used to indicate whether there is gas flow in the first gas outlet pipe 14 or the second gas outlet pipe 15. This can also indirectly help to remind whether the rotation angle of the ring cover 2 is in place.

[0043] Example 4: Reference Figure 6 An oxygen control valve structure is basically the same as that in Embodiment 3, but further: the three baffles 31 are provided with second dispersion holes 32. On the one hand, it does not affect the gas pushing the baffles 31 to drive the rotating shaft 3 to rotate. On the other hand, the second dispersion holes 32 can further disperse the oxygen and further improve the comfort of oxygen inhalation.

[0044] In this utility model, the ring cover 2 occupies a large proportion of the device, and the button plate 23 is long, so the user can easily adjust the opening and closing of the first air outlet pipe 14 and the second air outlet pipe 15 during adjustment.

[0045] In addition, the connecting plate 24 set in the arc-shaped tube groove 22 can disperse the oxygen passing through the arc-shaped tube groove 22. After the oxygen is dispersed, the oxygen and air are mixed more evenly, thereby improving the utilization rate of oxygen and making the oxygen inhalation effect better. Secondly, the dispersed oxygen flows more gently, reducing the discomfort of oxygen directly impacting the nasal cavity or respiratory tract and improving the comfort of the oxygen inhalation experience.

[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
