Description

Technical Field

[0001] The utility model relates to the technical field of oxygen generators, in particular to a medical oxygen generator capable of ensuring the initial oxygen supply concentration. Background Technique

[0002] As an essential gas for human survival, oxygen plays a very important role in daily life, especially in the process of medical first aid. Usually, the prepared oxygen is stored in a steel cylinder at low temperature and high pressure for emergencies, but it is extremely inconvenient to use. Therefore, oxygen generators came into being.

[0003] After retrieval, a utility model with the Chinese patent publication number CN219963693U discloses a new type of medical oxygen generator for the respiratory department, including a mobile platform. The top of the mobile platform is equipped with an oxygen generator body, and the top of the oxygen generator body is provided with a convenient disassembly mechanism.

[0004] Since the oxygen generator pipeline and the oxygen generation components contain air inside, during the initial operation, the oxygen is mixed with the air in them, resulting in insufficient oxygen concentration. At this time, the oxygen supply affects the patient's oxygen absorption. Therefore, a medical oxygen generator capable of ensuring the initial oxygen supply concentration is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a medical oxygen generator capable of ensuring the initial oxygen supply concentration to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A medical oxygen generator capable of ensuring the initial oxygen supply concentration, including an installation box, characterized in that: a machine body is installed inside the installation box, an air outlet pipe is installed on the top of the machine body, a discharge assembly is installed outside the air outlet pipe, the discharge assembly includes a branch pipe fixedly inserted in the middle of the air outlet pipe, a transition box is fixedly installed on one outer wall of the installation box, the transition box is communicated with the branch pipe, a piston plate is slidably connected inside the transition box, a plurality of first springs are fixedly connected between the piston plate and the transition box, an exhaust port is arranged at the top of one outer wall of the transition box, a first solenoid valve is installed at the top position of the air outlet pipe, and one second solenoid valve is installed outside each of the branch pipe and the exhaust port.

[0007] As a further preferred of this technical solution, a control button is fixedly installed on the bottom inner wall of the transition box, and a controller is installed outside the transition box. The first solenoid valve, the control button and the two second solenoid valves are all electrically connected to the controller through wires.

[0008] When the machine runs for the first time, the newly generated low-concentration oxygen can be directly discharged to the outside, so as to ensure that the oxygen concentration absorbed by the patient always remains relatively constant. In the initial state, the first solenoid valve and the second solenoid valve at the exhaust port are closed, and the oxygen will enter the transition box through the branch pipe. As the gas volume increases, the air pressure will push the piston plate to overcome the thrust of spring one, and then flow to the outside through the holes at the bottom. When the piston plate moves and presses on the top of the control button, the control button will control the opening of the first solenoid valve and the second solenoid valve at the exhaust port, and the second solenoid valve of the branch pipe will be closed. The subsequent oxygen is supplied to the outside through the air outlet pipe, and the low-concentration oxygen collected in the transition box is discharged to the outside to restore the initial state.

[0009] As a further optimization of this technical solution, a plurality of stabilizing rods are slidably inserted into the piston plate. The plurality of stabilizing rods are respectively located inside a plurality of spring ones, and both ends of the plurality of stabilizing rods are fixedly connected to the inner walls of the top and bottom of the transition box.

[0010] As a further optimization of this technical solution, a extension plate is fixedly connected to the bottom of the outer wall of one side of the installation box, and a cleaning component is installed on the top of the extension plate, and the cleaning component is located on one side of the air inlet of the machine body.

[0011] As a further optimization of this technical solution, the cleaning component includes two mounting rods fixedly connected to both ends of the outer wall of the top of the extension plate. The two mounting rods are slidably sleeved with the same mounting plate. A spring three is sleeved on each of the two extension plates. The two spring threes are both located at the bottom of the mounting plate. A motor is fixedly installed on the top outer wall of the air inlet of the machine body, and an eccentric drive disk is installed on the rotating shaft of the motor. The drive disk is in contact with the top wall of the mounting plate.

[0012] As a further optimization of this technical solution, two sliding rods are slidably inserted into the mounting plate. One end of the two sliding rods is fixedly connected to the same mounting frame. A non-drying adhesive roller is rotatably connected in the mounting frame, and the non-drying adhesive roller can be in contact with the filter screen at the air outlet of the machine body. A spring two is sleeved on the outside of each of the two sliding rods.

[0013] When the outside air enters the machine body, the impurities in it are intercepted by the filter screen at the air inlet. At the same time, by starting the motor to drive the drive disk to rotate eccentrically, the mounting plate will be driven by the drive disk to move up and down reciprocally under the cooperation of the spring three. The impurities on the surface of the filter screen will be cleaned by the non-drying adhesive roll of the mounting frame moving up and down, ensuring the air circulation rate. If the non-drying adhesive roll is full, just tear it off. As the diameter of the adhesive roll becomes smaller, the spring two will stretch and become longer, so that the new non-drying adhesive roll continues to fit on the surface of the filter screen, ensuring that the cleaning effect is always maintained, and the operation process is convenient enough.

[0014] The utility model provides a medical oxygen generator that can ensure the initial oxygen supply concentration, and has the following beneficial effects:

[0015] (1) By setting up the discharge component, the present utility model can directly discharge the newly generated low-concentration oxygen to the outside when the machine body runs for the first time, so as to ensure that the oxygen concentration absorbed by the patient always remains relatively constant. In the initial state, the first solenoid valve and the second solenoid valve at the exhaust port are closed, and the oxygen will enter the transition box through the branch pipe. As the gas volume increases, the air pressure will push the piston plate to overcome the thrust of spring one, and then flow to the outside through the holes at the bottom. When the piston plate moves and presses on the top of the control button, the control button will control the opening of the first solenoid valve and the second solenoid valve at the exhaust port, and the second solenoid valve of the branch pipe will be closed. The subsequent oxygen is supplied to the outside through the air outlet pipe, and the low-concentration oxygen collected in the transition box is discharged to the outside to restore the initial state.

[0016] (2) By setting up the cleaning component, when the external air enters the machine body, the impurities therein are intercepted by the filter screen at the air inlet. At the same time, by starting the motor to drive the driving disc to rotate eccentrically, the mounting plate will be driven by the driving disc to move up and down reciprocally under the cooperation of spring three. The impurities on the surface of the filter screen will be stuck clean by the adhesive tape roll of the mounting frame that moves up and down, ensuring the air circulation rate. If the adhesive tape roll is full, just tear it off. As the diameter of the adhesive tape roll becomes smaller, spring two will stretch and become longer, so that the new adhesive tape roll continues to fit on the surface of the filter screen, ensuring that the cleaning effect is always maintained, and the operation process is convenient enough.

[0024] A control button 508 is fixedly installed on the bottom inner wall of the transition box 502, and a controller is installed outside the transition box 502. The first electromagnetic valve 504, the control button 508, and the two second electromagnetic valves 505 are all electrically connected to the controller through wires.

[0025] A plurality of stabilizing rods 509 are slidably inserted into the piston plate 506. The plurality of stabilizing rods 509 are respectively inside the plurality of first springs 507, and both ends of the plurality of stabilizing rods 509 are fixedly connected to the top and bottom inner walls of the transition box 502.

[0026] In the initial state, the first electromagnetic valve 504 and the second electromagnetic valve 505 of the exhaust port 503 are closed, and oxygen will enter the transition box 502 through the branch pipe 501. As the gas volume increases, the air pressure will push the piston plate 506 to overcome the thrust of the first springs 507, and then flow out to the outside through the holes at the bottom. When the piston plate 506 moves and presses against the top of the control button 508, the control button 508 will control the opening of the first electromagnetic valve 504 and the second electromagnetic valve 505 of the exhaust port 503, and the second electromagnetic valve 505 of the branch pipe 501 will be closed. The subsequent oxygen is supplied to the outside through the air outlet pipe 4, and the low-concentration oxygen collected in the transition box 502 is discharged to restore the initial state.

[0027] As Figure 2 and Figure 3 shown, an extension plate 2 is fixedly connected to the bottom of one outer wall of the installation box 1, a cleaning assembly 6 is installed on the top of the extension plate 2, and the cleaning assembly 6 is on the side of the air inlet of the machine body 3.

[0028] The cleaning component 6 includes two mounting rods 601 fixedly connected to both ends of the outer wall of the top of the extension plate 2.

A third spring 608 is sleeved on each of the two extension plates 2, and both of the third springs 608 are located at the bottom of the mounting plate 602. A motor 603 is fixedly installed on the outer wall of the top of the air inlet of the machine body 3. An eccentric drive disk 604 is installed on the rotating shaft of the motor 603, and the drive disk 604 is in contact with the top wall of the mounting plate 602.

[0031] The utility model provides a medical oxygen generator that can ensure the initial oxygen supply concentration. The specific working principle is as follows:

In the initial state, the first solenoid valve 504 and the second solenoid valve 505 at the exhaust port 503 are closed. The oxygen will enter the transition box 502 through the branch pipe 501. As the gas volume increases, the air pressure will push the piston plate 506 to overcome the thrust of the first spring 507, and then flow out to the outside through the holes at the bottom. When the piston plate 506 moves and presses against the top of the control button 508, the control button 508 will control the opening of the first solenoid valve 504 and the second solenoid valve 505 at the exhaust port 503, and the second solenoid valve 505 of the branch pipe 501 will be closed. The subsequent oxygen is supplied to the outside through the air outlet pipe 4. The low-concentration oxygen collected in the transition box 502 is discharged outward to restore the initial state. When the external air enters the body 3, the impurities in it are intercepted by the filter screen at the air inlet. At the same time, by starting the motor 603 to drive the drive disk 604 to rotate eccentrically, the mounting plate 602 will be driven by the drive disk 604 to move up and down reciprocally under the cooperation of the third spring 608. The impurities on the surface of the filter screen will be cleaned by the adhesive tape of the mounting frame 606 that moves up and down, ensuring the air circulation rate. If the adhesive tape is full, just tear it off. As the diameter of the adhesive tape becomes smaller, the second spring 607 will stretch and become longer, so that the new adhesive tape continues to fit on the surface of the filter screen, ensuring that the cleaning effect is always maintained, and the operation process is convenient enough.
