DETAILED DESCRIPTION
[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.
[0021] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0022] The present utility model provides an oxygen production device with an early warning function, such as Figure 1-4 As shown, the oxygen generator with an early warning function comprises: a base box 1, a steerable placement seat 2 is arranged on the top of the base box 1; an oxygen generator body 3 arranged on the placement seat 2, and the oxygen generator body 3 comprises an oxygen outlet 4; a mounting plate 5 arranged above the oxygen outlet 4; an ultrasonic oxygen flowmeter 6 fixedly mounted on the bottom of the mounting plate 5; an early warning device 7 arranged on the mounting plate 5 and adapted to the ultrasonic oxygen flowmeter 6; and a driving mechanism arranged on the base box 1 for driving the placement seat 2 to turn.
[0023] It should be noted that, at present, the oxygen generators that supply oxygen indoors mainly use molecular sieve physical adsorption and desorption technology. The molecular sieve is filled in the oxygen generator, which can adsorb nitrogen in the air when pressurized, and the remaining unabsorbed oxygen is collected and purified to become high-purity oxygen; the molecular sieve discharges the adsorbed nitrogen back to the ambient air when decompressed, and can adsorb nitrogen and produce oxygen when pressurized next time. The whole process is a periodic dynamic cycle process, and the molecular sieve does not consume oxygen. Traditional oxygen generators have obvious limitations in design and function, especially in monitoring and early warning when there is no oxygen discharged from the oxygen outlet. In practical applications such as medical, industrial and household, if the oxygen generator fails to discharge oxygen from the oxygen outlet, and the operator or user fails to discover it in time, it may cause a series of safety problems; for example, in a medical environment, for patients who rely on oxygen generators for oxygen supply, once the oxygen supply is interrupted, the patient may face life-threatening danger due to lack of oxygen; in addition, a long-term interruption of oxygen supply may also cause equipment damage and increase maintenance costs;
[0024] In this embodiment, the base box 1 serves as the foundation and supporting structure of the entire oxygen generator. It is firmly placed on the ground to provide stable support for other components. The steerable placement seat 2 is located on the top of the base box 1 and is designed with a steering function, allowing the (YU100 type) oxygen generator body 3 to be conveniently adjusted in angle when needed, which is convenient for operation and adapting to different use environments. The oxygen generator body 3 is installed on the placement seat 2 and is the core part of the oxygen generator, including all components and mechanisms for oxygen production. The oxygen outlet 4 is located at a specific position of the oxygen generator body 3 and is used to transport the produced oxygen to the required place. The mounting plate 5 is arranged above the oxygen outlet 4 and is used to install and fix the (Gasboard-8500FS type) ultrasonic oxygen flowmeter 6 and the (JSA5-O2-A type) early warning device 7. The ultrasonic oxygen flowmeter 6 is fixedly installed at the bottom of the mounting plate 5 and monitors the oxygen flow of the oxygen outlet 4 in real time through ultrasonic technology. Once an abnormal oxygen flow rate is detected (such as zero flow rate, indicating no oxygen is discharged), it will immediately send a signal to the early warning device 7; the early warning device 7 is installed on the mounting plate 5 and is adapted to the ultrasonic oxygen flow meter 6. When receiving the abnormal signal sent by the ultrasonic oxygen flow meter 6, the early warning device 7 will immediately start and send out an audible and visual alarm signal to remind the operator or user to pay attention to the problem of oxygen supply interruption; it is set on the base box 1 to drive the placement seat 2 to turn. This allows the oxygen generator body 3 to adjust the angle as needed, which is convenient for operation and maintenance; by integrating the ultrasonic oxygen flow meter 6 and the early warning device 7, the oxygen generator can monitor the oxygen flow rate of the oxygen outlet 4 in real time, and immediately send out an early warning signal when an abnormal situation is found, which greatly improves the reliability and safety of the oxygen supply; the introduction of the early warning function enables the operator or user to promptly discover the problem of oxygen supply interruption and take corresponding measures to solve it. This reduces the safety risks such as patient hypoxia and equipment damage caused by oxygen supply interruption.
[0025] In a further preferred embodiment of the utility model, the driving mechanism includes: a rotating shaft 9 rotatably mounted on the base box 1, the bottom end of the rotating shaft 9 extending into the base box 1; a groove block 10 fixedly mounted on the top end of the rotating shaft 9; a plug-in block 11 arranged on the groove block 10, the top end of the plug-in block 11 is fixedly connected to the bottom of the placement seat 2; a motor 12 fixed in the base box 1 for driving the rotating shaft 9 to rotate; a first gear 13 assembled on the output shaft of the motor 12; a second gear 14 fixed on the bottom end of the rotating shaft 9, the second gear 14 meshing with the first gear 13.
[0026] In this embodiment, the rotating shaft 9 is rotatably mounted on the base box 1, and its bottom end extends into the base box 1. As the main rotating component, it connects the base box 1 and the placement seat 2; the groove block 10 is fixedly mounted on the top of the rotating shaft 9, forming a groove that can accommodate the plug-in block 11. The groove block 10 rotates with the rotation of the rotating shaft 9; the plug-in block 11 is arranged on the groove block 10, and its top end is fixedly connected to the bottom of the placement seat 2. The cooperation between the plug-in block 11 and the groove block 10 enables the placement seat 2 to rotate with the rotation of the groove block 10; the motor 12 is fixed in the base box 1, as a power source for driving the rotating shaft 9 to rotate. The selection of the motor 12 should take into account that its driving torque and speed match the torque and speed required for the rotation of the placement seat 2; the first gear 13 is assembled on the output shaft of the motor 12, and rotates with the rotation of the motor 12; the second gear 14 is fixed at the bottom end of the rotating shaft 9 and meshes with the first gear 13. When the motor 12 drives the first gear 13 to rotate, due to the meshing relationship between the gears, the second gear 14 will rotate accordingly, thereby driving the rotation of the rotating shaft 9 and the groove block 10, and finally realizing the steering of the placement seat 2; the motor 12 drives the meshing rotation of the first gear 13 and the second gear 14, thereby realizing the flexible steering of the placement seat 2. This allows the oxygen production device to conveniently adjust the direction of the oxygen outlet 4 according to the actual use environment and needs, thereby improving the convenience of use; the use of gear transmission ensures the stability and reliability of the rotation process. At the same time, by selecting the appropriate number of gear teeth and modulus, the transmission ratio can be adjusted to make the steering more stable and precise.
[0027] In a further preferred embodiment of the utility model, a support column 15 is symmetrically fixedly installed on the bottom of the placement seat 2, and a ball 16 is embedded on the bottom end of the support column 15. An annular groove is opened on the top of the base box 1, and the annular groove is adapted to the ball 16.
[0028] In this embodiment, the support column 15 is symmetrically fixedly installed at the bottom of the placement seat 2 to provide stable support for the placement seat 2. The design of the support column 15 can ensure that the placement seat 2 maintains balance during rotation, reducing shaking and tilting; the ball 16 is embedded in the bottom end of the support column 15 as a rolling contact point between the placement seat 2 and the base box 1. The material of the ball 16 should have a certain hardness and wear resistance to ensure good rolling performance during long-term use; the annular groove is opened at the top of the base box 1, which is compatible with the ball 16. The design of the annular groove should ensure that the ball 16 can roll smoothly therein, while limiting the rotation range of the placement seat 2 to prevent it from over-rotating or detaching from the base box 1; through the design of the support column 15 and the ball 16, the placement seat 2 can achieve more stable rolling when rotating. The cooperation of the ball 16 and the annular groove reduces friction, makes the rotation smoother, and reduces noise and vibration; the symmetrically installed support column 15 provides uniform support for the placement seat 2 and enhances its stability during rotation. This design helps to prevent the placement seat 2 from tilting or shaking when rotating, thereby ensuring the overall stability of the oxygen production device.
[0029] In a further preferred embodiment of the utility model, a limiting groove is symmetrically provided on the inner wall of the bottom of the placement seat 2, a limiting block 17 is arranged in the limiting groove, and the limiting block 17 is fixedly connected to the oxygen generator body 3.
[0030] In this embodiment, the limiting groove is symmetrically arranged on the bottom inner wall of the placement seat 2, and its shape and size match the limiting block 17 to ensure that the limiting block 17 can be stably placed therein; the limiting block 17 is designed in the limiting groove and is fixedly connected to the oxygen concentrator body 3. This design ensures the stability of the oxygen concentrator body 3 on the placement seat 2 and limits its range of movement relative to the placement seat 2; through the cooperation of the limiting groove and the limiting block 17, the oxygen concentrator body 3 is firmly fixed on the placement seat 2, reducing the shaking and vibration that may occur during the operation of the equipment, thereby improving the stability and safety of the oxygen concentrator; the design of the limiting block 17 effectively prevents the possibility of the oxygen concentrator body 3 accidentally falling off from the placement seat 2, especially when the equipment is subjected to external impact or vibration, this design can provide additional safety protection.
[0031] In a further preferred embodiment of the utility model, a slide block for transferring the mounting plate 5 is symmetrically fixedly installed on the oxygen generator body 3, and a bolt is provided on the slide block, and the bottom end bolt of the bolt passes through the mounting plate 5.
[0032] In this embodiment, the slide block is symmetrically fixedly mounted on the oxygen concentrator body 3, and is designed with a slide matching the mounting plate 5 to guide the accurate installation position of the mounting plate 5; the bolt is arranged on the slide block, and its bottom end penetrates the mounting plate 5 to fix the mounting plate 5 on the oxygen concentrator body 3. The head of the bolt is designed with a structure that is easy to rotate and lock, so as to ensure the stability of the mounting plate 5.
[0033] In a further preferred embodiment of the utility model, a plurality of streamers 8 are fixedly mounted on the mounting plate 5 , and a plurality of foot pads are symmetrically fixedly mounted on the bottom of the base box 1 .
[0034] In this embodiment, the streamers 8 are fixedly mounted on the mounting plate 5. The material of the streamers 8 is usually light and has good flowability. Therefore, when oxygen is discharged, they will float, which is convenient for personnel to intuitively judge whether oxygen is discharged. The multiple foot pads symmetrically fixedly mounted on the bottom of the base box 1 are to ensure that the oxygen concentrator can be stably placed on the ground; the foot pads are usually made of materials with certain elasticity and anti-slip properties, such as rubber or silicone, which helps to increase the friction between the equipment and the ground to prevent sliding. In addition, the foot pads can also reduce the noise and vibration generated when the equipment is running to a certain extent, and improve the comfort of use.
[0035] In a further preferred embodiment of the utility model, an inspection opening is provided on one side of the base box 1, an openable and closable box door is provided in the inspection opening, a hinge and a handle lock are provided on the box door, and the hinge is fixedly connected to the base box 1.
[0036] In this embodiment, an inspection port is provided on one side of the base box 1, which provides a convenient passage for the internal maintenance and inspection of the equipment. The position and size of the inspection port are carefully designed to ensure that the hands or tools of maintenance personnel can enter without affecting the overall structure and appearance of the equipment; a closable door is provided in the inspection port for closing or opening the inspection port. The door and the inspection port are connected by a hinge, so that the door can be opened and closed flexibly; the hinge is fixedly connected to the base box 1 to support the opening and closing movement of the door. The installation position and angle of the hinge are accurately calculated and adjusted to ensure that the door can move smoothly and smoothly during the opening and closing process.

[0037] In summary, by integrating the ultrasonic oxygen flowmeter 6 and the early warning device 7, the oxygen generator can monitor the oxygen flow rate of the oxygen outlet 4 in real time and immediately send out an early warning signal when an abnormal situation is found, which greatly improves the reliability and safety of the oxygen supply; the introduction of the early warning function enables the operator or user to promptly discover the problem of oxygen supply interruption and take corresponding measures to solve it.

The ultrasonic oxygen flowmeter 6 fixed on the mounting plate 5 can monitor the oxygen flow of the oxygen outlet 4 in real time. Once an abnormality is detected, such as zero flow, a signal will be sent to the early warning device 7. After receiving the signal, the early warning device 7 starts immediately and sends an audible and visual alarm signal to remind the operator or user to pay attention to the problem of oxygen supply interruption, thereby ensuring the reliability and safety of oxygen supply.
