[0034] In this embodiment, the lower part of the fixed seat 1 is tightly fitted on the port of the portable oxygen cylinder, and the lower part of the valve seat 2 is fixedly connected to the upper part of the fixed seat 1; the outlet valve on the port of the portable oxygen cylinder passes through the central hole 1-4 of the lower inner cavity of the fixed seat 1 and enters the central cylindrical hole 2-4 of the lower inner cavity of the valve seat 2 to form an oxygen outlet channel; a Tesla valve core 3 is installed in the upper inner cavity of the valve seat 2, and the pressure seat 4 is inserted into the upper inner cavity of the valve seat 2 to press the Tesla valve core 3, a steel ball placement cavity 4-1 is provided at the center of the pressure seat 4, a valve port 4-4 is provided at the center of the bottom surface of the steel ball placement cavity 4-1, and a steel ball 5 for opening and closing the valve port 4-4 is placed in the steel ball placement cavity 4-1, the upper cover 6 is fixedly connected to the upper part of the valve seat 2 to press the pressure seat 4, and the steel ball placement cavity 4-1 forms a sealed space, an air outlet hole 6-3 is provided in the center of the upper cover 6, and a mask 7 is connected to the upper part of the upper cover 6.

[0035] In a specific embodiment, see Figure 3 , Figure 4As shown, the fixing seat 1 is an inverted trumpet-shaped structure, the upper outer circumferential surface of the fixing seat 1 is provided with a fixing seat external thread 1-1, the lower inner circumferential surface of the valve seat 2 is provided with a valve seat internal thread 2-3, and the valve seat internal thread 2-3 and the fixing seat external thread 1-1 are screwed together; a snap step 1-3 for connecting with the port of a portable oxygen cylinder is provided in the lower inner cavity of the fixing seat 1, a center hole 1-4 for allowing the outlet valve on the port of the portable oxygen cylinder to pass through is provided in the center of the lower inner cavity of the fixing seat 1, and a marking character 1-2 is provided on the trumpet-shaped outer circumferential surface of the fixing seat 1.

[0036] In this embodiment, the outer thread 1-1 of the fixing seat on the upper part of the fixing seat 1 is screwed with the inner thread 2-3 of the valve seat to support the main body. The internal buckle step 1-3 is tightly matched with the port of the portable oxygen cylinder, and the oxygen cylinder outlet valve passes through the central hole 1-4 and enters the central cylindrical hole 2-4 of the valve seat to form an oxygen outlet channel.

[0037] In a specific embodiment, see Figure 5 , Figure 6 As shown, a central cylindrical hole 2-4 for wrapping the outlet valve of the portable oxygen cylinder mouth is provided at the center of the lower inner cavity of the valve seat 2; a buckle 2-1 is provided on the upper inner circular surface of the valve seat 2, and a groove 4-3 for engaging with the buckle 2-1 is provided on the outer circular surface of the pressure seat 4; a valve seat external thread 2-2 is provided on the upper outer circular surface of the valve seat 2, and an upper cover internal thread 6-6 for screwing with the valve seat external thread 2-2 is provided on the inner circular surface of the upper cover 6.

[0038] In this embodiment, the Tesla valve core 3 is installed in the inner cavity of the valve seat 2, and the buckle 2-1 cooperates with the groove 4-3 on the pressure seat, and the Tesla valve core 3 is pressed by the pressure seat 4 to form a whole with the valve seat 2. The inner cavity of the central cylindrical hole 2-4 at the lower part of the valve seat wraps the oxygen cylinder outlet valve. When it is screwed in the circumferential direction, it is guided by the thread to move downward as a whole, and the inner end surface of the central cylindrical hole 2-4 presses the oxygen cylinder outlet valve to control its opening degree.

[0039] In a specific embodiment, see Figure 1 As shown, the Tesla valve core 3 is designed as a double-sided arc airflow channel. By using the reverse flow principle of the Tesla valve, the diverted channel fluid interacts with the main channel fluid to form interference resistance loss pressure, and the flow rate is slowed down to become a leakage amount, achieving the purpose of steady flow delay. When the gas passes through, the slight sound generated by turbulence becomes a sign of oxygen output.

[0040] In a specific embodiment, see Figure 7 As shown, a conical sleeve is provided in the middle of the pressure seat 4, and a conical sleeve is also provided in the middle of the inner cavity of the upper cover 6. After the upper cover 6 is screwed on, the inner conical surface 6-5 of the conical sleeve on the pressure seat 4 is tightly fitted with the outer conical surface 4-2 of the conical sleeve on the pressure seat 4, and the inner cavity of the conical sleeve on the pressure seat 4 forms a steel ball placement cavity 4-1.

[0041] In this embodiment, the outer conical surface 4-2 of the pressure seat 4 cooperates with the inner conical surface 6-5 of the upper cover. When the inner thread of the upper cover is screwed into the outer thread of the valve seat 2, as the screwing depth of the thread increases, the conical surfaces are pressed tightly together, and the upper cover end face 6-4 and the pressure seat form an inner cavity for placing the steel ball. When tightening, it is ensured that the steel ball has a gap in the cavity and will not shift.

[0042] In a specific embodiment, see Figure 8 As shown in 9, a top 6-2 is provided at the center of the upper portion of the upper cover 6, and a filter element mounting cavity 6-1 for placing the filter element is provided in the top 6-2. The air outlet 6-3 at the center of the upper cover 6 is connected to the filter element mounting cavity 6-1, and the end surface 6-4 at the center of the upper cover 6 is used to embed the steel ball into the inner cavity 4-1.

[0043] In this embodiment, the top 6-2 of the upper cover 6 is used to clamp the small hole 7-3 at the lower end of the mask 7, and the filter element is embedded in the filter element installation cavity 6-1, and the oxygen is filtered and transported into the mask. The upper end surface is designed with the company logo and operation indication arrows.

[0044] In a specific embodiment, see Fig.10 As shown, the lower end of the mask 7 is provided with a lower small hole 7-3 for clamping on the top end 6-2, the upper end of the mask 7 is provided with an opening 7-1 for covering the user's mouth and nose, and the side of the mask 7 is provided with a safety opening 7-2.

[0045] In this embodiment, the opening 7-1 at the upper end of the mask 7 can cover the user's mouth and nose, the end surface is flanged and made of soft silicone material to ensure the user's comfort, and the side 7-2 is a safety opening.

[0046] The gas circuit diagram of this oxygen supply controller is referenced Fig.11 As shown. When the outlet valve of the oxygen cylinder is pressed down, the oxygen in the cylinder enters the cavity where the steel ball is located through the valve port. Assuming that the oxygen pressure in the cylinder is P0 (it is a variable, first large and then small), the pressure after the Tesla valve core is reduced is P0'. Because it is greater than the external atmospheric pressure and the weight of the steel ball G, the center hole blocked by the steel ball is pushed open to fill the cavity where the steel ball is located. The pressure in the cavity gradually rises, assuming it is P1. When the pressure reaches equilibrium, that is, P0'=P1+G, the steel ball sinks to block the valve port, blocking the oxygen passage. The size of the steel ball is designed according to the required oxygen output and the need for pressure balance.

[0047] When the user inhales through the mask, a certain negative pressure is formed in the cavity where the steel ball is located, P1 decreases, P0' can push the steel ball away, and oxygen flows out from the gap at the lower end to the mask; when the user exhales, the exhaled gas pressure increases P1, and the steel ball sinks to block the valve port, thereby matching breathing with oxygen output, achieving lung control, and saving oxygen.

[0048] After the overall assembly of the oxygen supply controller, the test shows that a bottle of portable oxygen supply can be used for about 40 minutes under the condition of low-flow oxygen supply, which reduces oxygen waste and improves oxygen use efficiency.

[0049] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention, and any figure mark in the claims should not be regarded as limiting the claims involved.

[0050] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
