Description

Technical Field

[0001] This invention belongs to the field of control valve technology, specifically relating to an oxygen supply controller for oxygen cylinders. Background Technology

[0002] Portable oxygen concentrators are widely used in daily production and life in oxygen-deficient high-altitude areas and among people with special needs. Currently, the mainstream specifications of portable oxygen concentrators on the market are 1L capacity and 0.8MPa pressure. There are two usage methods: nasal inhalation and oral inhalation. The usage time of one bottle of oxygen is about 3 minutes. Since the released oxygen is not controlled, there is a lot of waste. Therefore, it is necessary to design an oxygen supply controller to effectively extend the oxygen usage time. Summary of the Invention

[0003] The technical problem solved by this invention is to provide an oxygen supply controller for oxygen cylinders. This invention innovatively applies the principle of Tesla valve to the oxygen supply controller, which can provide a stable output flow while keeping the structure simple, thus extending the service life of a portable oxygen supply device. Furthermore, by adding humidifying materials, it effectively improves the user experience.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An oxygen supply controller for an oxygen cylinder includes a mounting base, a valve seat, a Tesla valve core, a humidification cup, a humidification material, a nozzle, and a top cover;

[0006] The lower part of the fixed seat is tightly fitted to the bottle opening of the portable oxygen supply device. The lower inner circle of the valve seat and the upper outer circle of the fixed seat are connected together by a rotating gear selection structure. The outlet valve on the bottle opening passes through the central hole of the lower inner cavity of the fixed seat and enters the central cylindrical hole in the lower inner cavity of the valve seat to form an oxygen outlet channel.

[0007] The Tesla valve core is installed in the upper inner cavity of the valve seat. The lower end face of the humidification cup is in close contact with the upper end face of the Tesla valve. Humidification material is placed in the upper inner cavity of the humidification cup. The lower end of the nozzle is pressed into the humidification cup. The upper end of the nozzle extends through the center hole of the upper cover to connect with the nasal cannula. The upper cover wraps the stacked Tesla valve core, humidification cup, humidification material and nozzle and fastens them to the upper outer circle of the valve seat to form a whole.

[0008] The fixing base has an inverted horn-shaped structure. The outer circular surface of the horn-shaped base is marked with gear marking lines and characters. The upper outer circular surface of the fixing base has three arc-shaped tracks evenly distributed at 120° intervals. The trajectory of the arc-shaped tracks is designed according to the downward and upward stroke required by the oxygen cylinder opening valve. The tracks correspond to the marking lines and characters on the outer circular surface of the horn-shaped base at 30° intervals. Each arc-shaped track has three small arcs on its upper side for the rotation and locking of the oxygen supply controller. The lower inner cavity of the fixing base has a buckling step for connecting with the bottle opening of the portable oxygen supply device. The center of the lower inner cavity of the fixing base has a central hole through which the outlet valve on the oxygen supply device bottle opening passes. The upper outer edge of the fixing base has a constricted opening that connects with the arc-shaped tracks and is used for limiting and preventing the oxygen supply controller body from detaching.

[0009] Furthermore, the lower inner cavity of the valve seat has a central cylindrical hole for wrapping the outlet valve of the oxygen supply bottle. The lower inner circular surface of the valve seat has three cylindrical protrusions that are equally divided along the circumference and used to engage with the arc-shaped track. The lower outer circular surface of the valve seat has three raised ridges as positioning marks and used to indicate the initial assembly position. The orientation of the raised ridges corresponds to the three cylindrical protrusions that are equally divided along the circumference. The upper outer circular surface of the valve seat has a stepped surface for fastening together with the upper cover.

[0010] Furthermore, the Tesla valve core adopts a double-sided circular channel structure.

[0011] Furthermore, the humidifying material is granular SAP superabsorbent polymer.

[0012] Furthermore, the outer circular surface of the upper cover is provided with raised circular ridges.

[0013] Advantages of this invention compared to existing technologies:

[0014] 1. This solution is applicable to portable oxygen dispensers with capacities from 0.5ML to 2L. It integrates a design that provides stable flow rate with graded output and oxygen humidification effect, effectively extending the usage time of a portable oxygen dispenser to 20 minutes.

[0015] 2. This solution is the first to apply Tesla valves to the field of oxygen supply control, and it has innovatively designed a double-sided circular track Tesla valve, which uses its reverse turbulence principle to control the flow rate and achieve the purpose of steady flow delay.

[0016] 3. This solution adds a humidifying material, SAP water-absorbing resin, to the end of the oxygen supply controller to meet actual usage needs and improve user experience. This is a feature that existing oxygen supply control products do not have.

[0017] 4. This solution features 3-point positioning, allowing for operation of opening, adjusting, and closing the oxygen supply at levels 1, 2, and 3 within a 120° rotation radius, thus meeting the diverse oxygen needs of different users. Opening, adjusting, and closing operations can be performed regardless of whether the rotation is clockwise or counterclockwise, eliminating the need to change direction and making it easy to use.

[0018] 5. This solution has a simple structural design, is easy to mold, easy to assemble, and easy to automate production. It can effectively control costs and improve production efficiency. It is simple and convenient for users to operate, requires no special tools, and is easy and effortless to screw on. It provides a good user experience and has high oxygen utilization efficiency.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0027] Please see Figure 1-6 The embodiments of the present invention are described in detail below.

[0028] An oxygen supply controller for oxygen cylinders, the appearance of which is shown in the figure. Figure 1 Includes a fixed base 1, valve seat 2, Tesla valve core 3, humidification cup 4, humidification material 5, air nozzle 6, and upper cover 7; see exploded view. Figure 2 As shown.

[0029] The specific connection structure is as follows: the lower part of the fixed base 1 is tightly fitted onto the mouth of the portable oxygen supply device; the lower inner circle of the valve seat 2 and the upper outer circle of the fixed base 1 are connected together by a rotating gear selection structure; the outlet valve on the mouth of the oxygen supply device passes through the central hole of the lower inner cavity of the fixed base 1 and enters the central cylindrical hole in the lower inner cavity of the valve seat 2 to form an oxygen outlet channel; the Tesla valve core 3 is installed in the upper inner cavity of the valve seat 2; the lower end face of the humidification cup 4 is tightly attached to the upper end face of the Tesla valve 3; the upper inner cavity of the humidification cup 4 contains humidification material 5; the lower end of the nozzle 6 is pressed into the humidification cup 4; the upper end of the nozzle 6 extends through the central hole of the upper cover 7 to connect with the nasal cannula, forming an oxygen supply channel. The upper cover 7 wraps the stacked Tesla valve core 3, humidification cup 4, humidification material 5, and nozzle 6 and fastens them to the upper outer circle of the valve seat 2 with a snap-fit ​​structure to form a whole.

[0030] In this controller, the mounting base is tightly fitted to the bottle opening of the portable oxygen supply unit, and the rest of the components are fixed together. During use, the controller is rotated relative to the mounting base to the various positions indicated by the mounting base to turn the oxygen supply unit on and off.

[0031] In one embodiment, see Figure 3 As shown, the fixed base 1 has an inverted trumpet-shaped structure. The outer surface of the trumpet shape is marked with gear positions and characters 1-4. Three arc-shaped tracks 1-2 are evenly distributed at 120° intervals on the upper outer surface of the fixed base 1. The trajectory of the arc-shaped tracks 1-2 is designed according to the downward and upward stroke required by the oxygen cylinder's opening valve. They correspond to the markings and characters 1-4 on the outer surface of the trumpet shape at 30-degree intervals, representing the positions of closed, 1st gear, 2nd gear, and 3rd gear, corresponding to the closed, low-flow, medium-flow, and high-flow opening positions of the oxygen cylinder's outlet valve. Each arc-shaped track 1-2 has three small arcs 1-3 on its upper side. When the oxygen supply controller rotates along the track, it is pressed into the arc surface by the oxygen pressure and locked in place. When a gear change is needed, it is pushed out of the arc surface by hand and continues to move along the track. The lower inner cavity of the fixing base 1 is provided with a snap-fit ​​step 1-5 for connecting with the bottle mouth of the portable oxygen supply device. The fixing base 1 is tightly fitted to the bottle mouth of the portable oxygen supply device through the snap-fit ​​step 1-5. The center of the lower inner cavity of the fixing base 1 is provided with a central hole 1-6 through which the outlet valve on the bottle mouth of the oxygen supply device passes. The upper outer edge of the fixing base 1 is provided with a constriction 1-1 that connects with the arc-shaped track 1-2. The constriction 1-1 is used to limit and prevent the oxygen supply controller body from falling off after it is snapped in.

[0032] In one embodiment, see Figure 4 As shown, the upper inner cavity of the valve seat 2 is equipped with a Tesla valve core 3, and the lower inner cavity of the valve seat 2 has a central cylindrical hole 2-1 for wrapping the outlet valve of the oxygen supply bottle. The lower inner circular surface of the valve seat 2 has three cylindrical protrusions 2-4 that are equally divided along the circumference and used to engage with the arc-shaped track 1-2. The lower outer circular surface of the valve seat 2 has three raised ridges 2-2 as positioning marks and used to indicate the initial assembly position. The orientation of the raised ridges 2-2 corresponds to the three cylindrical protrusions 2-4 that are equally divided along the circumference. The upper outer circular surface of the valve seat 2 has a stepped surface 2-3 for fastening together with the upper cover 7 to achieve a snap-fit ​​engagement.

[0033] During assembly, the raised ridge 2-2 of valve seat 2 is aligned with the "close" or constriction 1-1 on the flared surface of fixed seat 1 and pressed in. The three cylindrical protrusions 2-4 are engaged in the arc track 1-2 of fixed seat 1. When rotating in the circumferential direction, the whole body is guided to move down by the arc track 1-2. The inner end face of the central cylindrical hole 2-1 presses the oxygen cylinder outlet valve to control its opening degree.

[0034] If rotated counterclockwise, the oxygen output increases from level 1 to level 3. After level 3, the track moves upward, valve seat 2 moves upward, and the outlet valve closes. If rotated clockwise, the oxygen output decreases from level 3 to level 1. After level 1, the track moves upward, and the outlet valve closes. In actual operation, based on user habits, regardless of which direction you rotate, the closing operation can be achieved in the same direction without needing to reverse the rotation.

[0035] The above-described structure features three-point positioning, enabling the operation of opening, adjusting, and closing the device within a 120° circumferential rotation range. This caters to the diverse oxygen needs of different users. The device can be opened, adjusted, and closed regardless of whether the rotation is clockwise or counterclockwise, eliminating the need for reversing direction and making it easy to use.

[0036] In one embodiment, see Figure 5-6 As shown, the Tesla valve core 3 adopts a double-sided circular channel structure. The working principle of the Tesla valve core is that the resistance to forward flow of gas or liquid is very small, the pressure loss is minimal, and the flow velocity is very high. During reverse flow, the fluid in the branch channel interacts with the fluid in the main channel, forming interference resistance, resulting in a larger pressure loss and a reduced flow velocity that becomes leakage. In this controller, utilizing the reverse characteristic of the Tesla valve, through reasonable parameter design, its reverse flow is maintained within a reasonable and stable range, achieving the purpose of steady flow delay. The slight sound generated by turbulence when gas passes through serves as an indication of oxygen output.

[0037] This structure is the first to apply the Tesla valve core to the field of oxygen supply control, and it has innovatively designed a double-sided circular track Tesla valve. It uses its reverse turbulence principle to control the flow rate and achieve the purpose of steady flow delay. It not only meets the product application requirements, but also makes full use of space, realizing the pioneering application of Tesla valve.

[0038] In one embodiment, the humidifying material 5 is granular SAP water-absorbing resin, which has the characteristic of swelling after absorbing water. The soaking time is based on the standard that no liquid water is released. When oxygen flows through, it can absorb the water saturated in the SAP particles to achieve a humidification effect and improve the oxygen inhalation experience.

[0039] This controller adds a humidifying material, SAP (Symptomyces hydrophobic resin), to the end of the oxygen supply controller to meet actual usage needs and improve user experience. This is a feature not found in existing oxygen supply control products.

[0040] In one embodiment, the outer circular surface of the upper cover 7 is provided with raised rounded edges, which serves two purposes: to improve the feel during operation and to enhance the aesthetics.

[0041] During use, the controller is installed at the opening of the portable oxygen concentrator bottle. By rotating it to different settings, the opening size of the oxygen cylinder valve is controlled, outputting different flow rates of humidified oxygen to meet the needs of different users. Testing shows that one portable oxygen concentrator bottle can be used for approximately 20 minutes with a low flow rate and approximately 10 minutes with a high flow rate; optimizing user experience, reducing oxygen waste, and improving oxygen utilization efficiency.

[0042] This oxygen supply controller is suitable for portable oxygen dispensers with capacities ranging from 0.5ml to 2L. It integrates a tiered output with stable flow rate and effective oxygen humidification, effectively extending the usage time of a single oxygen cylinder. Its simple structural design facilitates molding and assembly, enabling automated production, effectively controlling costs and improving production efficiency. User operation is simple and convenient, requiring no special tools; screwing it on is easy and effortless. It provides a superior user experience and high oxygen utilization efficiency.

[0043] It will be apparent 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 invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.

[0044] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
