[0019] The present invention will be further described below with reference to the accompanying drawings and some embodiments.

[0020] exist Figure 1-Figure 3In the invention, a novel vending oxygen concentrator is provided, comprising an oxygen concentrator body 1, wherein the oxygen concentrator body 1 comprises an oxygen concentrator 2 for producing oxygen, a storage unit 3 for storing oxygen, and wheels 106 for moving the oxygen concentrator. The oxygen concentrator 2 is located above the storage unit 3, and a spring-loaded safety valve 207 is provided at the outlet of the oxygen concentrator 2 for automatically releasing oxygen under pressure. The output end of the spring-loaded safety valve 207 is connected to the input end of the storage unit 3. The spring-loaded safety valve 207 is a valve or plunger seal that is locked by the elastic pressure of the spring. Once the pressure of the pressure vessel is abnormal, the high pressure generated will overcome the spring pressure of the safety valve, so the locking device is pushed open, forming a pressure relief channel, which releases the high pressure. The pressure is released; the storage part 3 is located in an oxygen cylinder 301 including oxygen storage, a storage tank 303 for storing the oxygen cylinder 301, and a one-way valve 302 corresponding to the spring-loaded safety valve 207 is provided on the top of the oxygen cylinder 301. The one-way valve 302 is a directional control valve that allows airflow to flow in one direction but not in the reverse direction. The one-way valve 302 is docked with the spring-loaded safety valve 207 on the oxygen concentrator 2, and the oxygen concentrator 2 delivers oxygen to the oxygen cylinder 301. An arc-shaped slideway is provided inside the storage tank 303, which is placed obliquely as a whole, and is composed of an inlet slideway 304, a turning slideway 305, and an outlet slideway 306. The arc-shaped slideway is placed obliquely as a whole, which is convenient for oxygen concentrators. The gas cylinder 301 slides from top to bottom due to gravity. A movable platform 307 is respectively provided at the inlet slide 304 and the outlet slide 306 to drive the oxygen cylinder 301 to move. The movable platform 307 corresponds to the inlet and outlet of the cylinder storage bin 303 respectively. After the movable platform 307 at the inlet of the cylinder storage bin 303 rises, the spring-loaded safety valve 207 is squeezed and opens to release oxygen into the oxygen cylinder 301. When the movable platform 307 descends, the oxygen cylinder 301 follows the movable platform 307. Since the oxygen cylinder 301 is recycled, it has a certain weight and will not get stuck on the oxygen concentrator 2. A pressure sensor that senses the pressure of the oxygen cylinder 301 is provided on the movable platform 307. 308, a slide rail 309 for raising and lowering the movable platform 307 and a motor 310 for driving the movable platform 307 on the slide rail 309 are provided on the side of the movable platform 307. The output end of the pressure sensor 308 is connected to the input end of the motor 310. The pressure sensor 308 senses the pressure of the oxygen cylinder 301 and immediately begins to rise, and then oxygen is delivered to the oxygen cylinder 301 or the oxygen cylinder 301 is taken out. The storage unit 3 also includes a mask bin 316 for storing oxygen masks. The mask bin 316 is located on the side of the cylinder storage bin 303. A pushing component for pushing the oxygen mask is provided inside the mask bin 316. An input valve is provided on the side of the oxygen mask to communicate with the oxygen cylinder 301.

[0021] In this embodiment, the pushing assembly includes an electric telescopic rod 317 for pushing the oxygen mask and a protrusion 318 for snapping the oxygen mask. The protrusion 318 is located on both sides of the mask compartment 316. The electric telescopic rod 317 extends to push the oxygen mask upward. The electric telescopic rod 317 extends by the height of one oxygen mask each time, so that each time the electric telescopic rod 317 is extended, one oxygen mask is squeezed and moved from under the protrusion 318 to above the protrusion 318, thereby facilitating the removal of the oxygen mask. The maximum height of the electric telescopic rod 317 is the same as the height of the protrusion 318. After all the oxygen masks are pushed above the protrusion 318, the electric telescopic rod 317 is shortened. The oxygen mask is a disposable item and is made of soft materials such as plastic and silicone, so it will not be damaged during the pushing process.

[0022] In this embodiment, the entrance of the bottle storage bin 303, the exit of the bottle storage bin 303, and the exit of the mask bin 316 are all provided with solenoid valves 312 that can open and close automatically. The solenoid valve 312 is a common delay valve, and the time for delaying the closing of the valve can be set according to actual conditions. By opening the solenoid valve 312 at the entrance of the bottle storage bin 303, the used oxygen cylinder 301 can be placed on the mobile platform 307 for replenishing oxygen. By opening the solenoid valve 312 at the exit of the bottle storage bin 303, the oxygen cylinder 301 filled with oxygen can be taken out. By opening the solenoid valve 312 at the exit of the mask bin 316, the oxygen mask can be taken out.

[0023] In this embodiment, the mask compartment 316 is provided with an openable and closable cover 319 , and the cover 319 can be opened to add an oxygen mask into the mask compartment 316 .

[0024] In this embodiment, a lifting plate 311 is provided on the side of the movable platform 307 at the entrance of the cylinder storage bin 303 to block the oxygen cylinder 301. When the empty oxygen cylinder 301 is placed on the movable platform 307, the lifting plate 311 is in a lowered state to prevent the empty oxygen cylinder 301 from sliding directly into the cylinder storage bin 303 from the curved slide. After the oxygen cylinder 301 is filled with oxygen, the lifting plate 311 rises, allowing the oxygen cylinder 301 to slide into the cylinder storage bin 303 through the curved slide.

The output end of the microcontroller 103 is respectively connected to the input end of the oxygen generator 2, the input end of the storage unit 3, and the input end of the wheel 106. The microcontroller 103 is connected to the camera 102, the oxygen generator 2, the pressure sensor 308, the motor 310, the electric telescopic rod 317, the lifting plate 311, and the wheel 106, so that the liquid crystal panel 101 can control the oxygen generator body 1 through the microcontroller 103. A QR code is provided on the liquid crystal panel 101, and the oxygen cylinder 301 and the oxygen mask can be taken or returned by scanning the QR code using a mobile terminal such as a mobile phone.

[0026] In this embodiment, a battery 104 is provided in the oxygen generator body 1. The output end of the battery 104 is connected to the input end of the liquid crystal panel 101. The liquid crystal panel 101 is connected to the microcontroller 103. The microcontroller 103 is connected to the oxygen generator 2, the storage unit 3, and the wheel 106. Therefore, the battery 104 provides power to the oxygen generator body 1.

[0027] In this embodiment, the oxygen generator body 1 is provided with an interface 105 for charging the battery 104 . The output end of the interface 105 is connected to the input end of the battery 104 . The battery 104 is charged by connecting an external power source through the interface 105 .

[0028] In this embodiment, a guardrail 313 is provided on the side of the curved slide, and a slide bar 314 is symmetrically provided inside the guardrail 313 to prevent the oxygen cylinder 301 from falling from the side of the curved slide.

[0030] In this embodiment, the liquid crystal panel 101 is a common control panel, such as a ZZ-2020 model, an iTC602TAT-2 model, or the like.

[0031] In this embodiment, the microcontroller 103 is a programmable single chip microcomputer such as AT89C2051 or TMS320VC5509A.

[0032] In this embodiment, the solenoid valve 312 is a common time-delay switch device, such as a 2v025-08 series timing solenoid valve.

[0033] In this embodiment, the motor 310 is a common motor device, such as a 25BYZ series linear motor.

[0034] In this embodiment, the electric telescopic rod 317 and the lifting plate 311 are common electric telescopic devices, such as HB-DJ806, HTKC-55, NKLA34 telescopic rod devices, etc.

[0035] In this embodiment, the oxygen concentrator 2 is a common oxygen concentrator, such as a ZY-5AW oxygen concentrator.

[0036] In this embodiment, the control circuit of the present invention is a common circuit in the circuit field. The device of the present invention can be connected to an external power supply or a built-in battery through a power cord to provide power to the device. Technicians in the relevant technical field can implement it and will not be elaborated here.

[0037] When the utility model is implemented in detail: during use, the external power supply is connected to the interface 105 to charge the battery 104, the microcontroller 103 receives all signals and transmits the transmission signal, the camera 102 recognizes the road condition and causes the wheel 106 to drive the oxygen generator 1 to move within the known range. When it is necessary to take the oxygen cylinder 301 and the oxygen mask, the QR code on the liquid crystal panel 101 can be scanned by the mobile terminal. Then the solenoid valve 312 at the outlet of the storage bottle bin 303 is opened, and the mobile platform 307 drives the oxygen cylinder 301 to rise, so that the oxygen cylinder 301 passes through the solenoid valve 312 for easy taking of the oxygen cylinder 301. Then the mobile platform 307 descends and the solenoid valve 312 is closed, completing the operation of taking the oxygen cylinder 301. After the lifting platform descends, the oxygen cylinder 301 is moved to the front oxygen cylinder 301 on the mobile platform 307 due to the squeezing of the inclined surface and the rear oxygen cylinder 301, waiting for the next output of the oxygen cylinder 301.

The magnetic valve 312 opens, the electric telescopic rod 317 extends and transports the oxygen mask through the protrusion 318 to the outlet of the mask bin 316, making it easy to take the oxygen mask; when the oxygen cylinder 301 needs to be returned, the QR code is scanned by the mobile terminal, and then the electromagnetic valve 312 at the entrance of the cylinder bin 303 opens, the lifting plate 311 is in a lowered state, and the oxygen cylinder 301 is placed on the moving platform 307, and then the electromagnetic valve 312 closes, and the moving platform 307 drives the empty oxygen cylinder 301 to rise, so that the oxygen The one-way valve 302 on the bottle 301 is connected to the spring-loaded safety valve 207 on the oxygen concentrator 2. The oxygen concentrator 2 delivers oxygen into the oxygen bottle 301. Then the movable platform 307 drives the oxygen bottle 301 to descend, and the lifting plate 311 rises. Finally, the oxygen bottle 301 slides from the curved slide into the bottle storage bin 303. During the sliding process of the oxygen bottle 301, the guardrail 313 protects the oxygen bottle to prevent it from tipping over.
