It primarily utilizes the pressure swing adsorption (PSA) principle, adsorbing nitrogen and other gases from the air to extract high-purity oxygen. Currently, replacing the molecular sieve tank within an oxygen concentrator involves cumbersome disassembly and assembly, impacting the efficiency of maintenance and repair. Utility Model Content

[0003] To address the aforementioned problems, this invention proposes a medical oxygen generator that facilitates the replacement of molecular sieves, thereby more accurately resolving the problems described above.

[0004] This utility model is achieved through the following technical solution:

The top of the molecular sieve tank is provided with a pair of gas connectors, which are respectively an air inlet and an air outlet. The bottom of the molecular sieve tank is provided with an inner cavity of the component. Both sides of the inner cavity of the component are slidably connected with horizontally sliding limiting pins. The inner ends of the pair of limiting pins are integrally formed with racks, and a gear is provided between the racks at the inner ends of the pair of limiting pins. The gear meshes with the pair of racks for transmission, and the gear is rotatably connected to the inner cavity of the component.

[0006] Furthermore, the upper part of the base is integrally formed with a molecular sieve tank socket, the bottom of the molecular sieve tank is inserted into the molecular sieve tank socket, and limit pin holes are opened on both sides of the molecular sieve tank socket at the positions corresponding to the limit pins, and the limit pins are inserted into the corresponding limit pin holes.

[0007] Furthermore, the upper end of the gas connector is fitted with a gas nozzle, and the two gas nozzles are connected by a connecting frame. A spring is fitted on the outside of the gas connector, and the upper and lower ends of the spring abut against the top of the molecular sieve tank and the bottom of the connecting frame, respectively.

[0008] Furthermore, guide grooves are provided on both sides of the molecular sieve tank. The guide grooves are opened along the axial direction of the molecular sieve tank, and slide rods are slidably connected in the guide grooves.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model uses a sliding traction rod to drive the limiting pin to slide through the connecting rod, thereby controlling the limiting pin to retract. Then, the bottom of the molecular sieve tank is placed into the molecular sieve tank socket on the base. The limiting pin is then pulled out by the sliding rod, so that the limiting pin is inserted into the corresponding limiting pin hole, thereby completing the fixation of the molecular sieve tank. The fixing method is simple.

[0012] 2. The nozzle of this utility model is equipped with a retractable structure.

Figure 4 and Figure 5 As shown, the bottom of the molecular sieve tank 1 is provided with a component cavity 105. Both sides of the component cavity 105 are slidably connected with horizontally sliding limit pins 104. The outer end of the limit pins 104 is used for snap-fit ​​fixation. The inner end of each pair of limit pins 104 is integrally formed with a rack 1041, and a gear 1042 is provided between the racks 1041 at the inner end of the pair of limit pins 104. The gear 1042 meshes with the pair of racks 1041 for transmission. The gear 1042 is rotatably connected to the inner cavity of the component cavity 105, so that the pair of limit pins 104 can retract or pop out at the same time.

[0021] Both sides of the molecular sieve tank 1 are provided with guide grooves, which are opened along the axial direction of the molecular sieve tank 1. Sliding rods 103 are slidably connected in the guide grooves. The bottom ends of the two sliding rods 103 are hinged to connecting rods 1043, and the connecting rods 1043 are connected to corresponding limiting pins 104. By sliding and pulling the sliding rods 103, the sliding rods 103 drive the limiting pins 104 to slide through the connecting rods 1043, thereby controlling the limiting pins 104 to retract or extend.

[0022] It is worth mentioning that the guide grooves opened on both sides of the molecular sieve tank 1 are "T" shaped grooves, and the inner side of the slide rod 103 is provided with 1031 that cooperates with the guide groove to ensure the stability of the slide rod 103 when sliding.

[0023] The base 2 is used to fix it inside the oxygen generator. The upper part of the base 2 is integrally formed with a molecular sieve tank socket 201. The bottom of the molecular sieve tank 1 is inserted into the molecular sieve tank socket 201. Limiting pin holes 202 are opened on both sides of the molecular sieve tank socket 201 and at the corresponding positions of the limiting pins 104. The limiting pins 104 are inserted into the corresponding limiting pin holes 202, thereby completing the fixation of the molecular sieve tank 1.

[0024] The technical solutions in the above-described embodiments of this application have at least the following technical effects or advantages: This utility model uses the sliding traction of the slide rod 103 to cause the slide rod 103 to drive the limiting pin 104 to slide through the connecting rod 1043, thereby controlling the limiting pin 104 to retract. Then, the bottom of the molecular sieve tank 1 is placed into the molecular sieve tank socket 201 on the base 2, and the limiting pin 104 is ejected by the traction of the slide rod 103, so that the limiting pin 104 is inserted into the corresponding limiting pin hole 202, thereby completing the fixation of the molecular sieve tank 1. The fixing method is simple. Example 2

A spring 1022 is fitted onto the outside of the air connector 101. The air nozzle 102 has a telescopic structure, and an air passage socket for inserting the air nozzle 102 is provided in the oxygen generator, so that the air nozzle 102 can be inserted into the air connector 101, making the connection of the air connector 101 simpler.

[0026] The upper and lower ends of the spring 1022 abut against the top of the molecular sieve tank 1 and the bottom of the connecting frame 1021, respectively. The spring 1022 can stably connect the gas nozzle 102 to the gas inlet, and at the same time act on the slide rod 103 to keep the slide rod 103 pulling the limiting pin 104 in the popped-out state.

[0027] The technical solutions in the above-described embodiments of this application have at least the following technical effects or advantages: The nozzle 102 of this utility model is provided with a retractable structure, and an air passage socket for inserting the nozzle 102 is provided in the oxygen generator, so that the nozzle 102 in this utility model can be inserted into the air passage, thereby making the connection of the air connector 101 more convenient.

By pressing the connecting frame 1021, the nozzle 102 can be disengaged from the air passage connection. At the same time, by pulling the limiting pin 104 inward through the slide rod 103, the limiting pin 104 is disengaged from the limiting pin hole 202 on the molecular sieve tank socket 201, so that the molecular sieve tank 1 can be disassembled.
