[0002] At present, when a civilian hyperbaric oxygen chamber is in use, after closing the cabin door, it is usually necessary to further press the cabin door and the cabin body tightly by means of external pushing and pulling assistance, so as to improve the sealing performance between the cabin door and the cabin body. After the hyperbaric oxygen chamber is supplied with oxygen, oxygen is not easy to leak out through the door gap, and then the air pressure in the oxygen chamber is increased. This method of external pushing and pulling assistance is cumbersome to operate, inconvenient to use, and difficult to meet the actual use requirements. Content of the Utility Model

[0003] The purpose of the utility model is to provide an electromagnetic door sucker hyperbaric oxygen chamber. When the electromagnetic door sucker hyperbaric oxygen chamber closes the cabin door, the buffer bump is pressed by the electromagnet and retracts into the buffer hole. Due to the buffering effect of the buffer spring, the electromagnet and the iron block can achieve soft contact when approaching gradually. Then, by using the attraction between the energized electromagnet and the iron block, the outer edge of the cabin door can be further pressed against the cabin body to achieve the sealing between the cabin door and the cabin body. When the electromagnet is powered off, under the restoring force of the buffer spring, the electromagnet and the iron block can be separated. The operation is simple and the use effect is good.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] Furthermore, guide rods are respectively arranged on both sides of the installation plate; one end of the guide rod is fixedly connected to the cabin body, and the other end of the guide rod penetrates through the installation plate; the installation spring is sleeved outside the guide rod between the installation plate and the cabin body.

[0008] Further, an electromagnetic door sucker hyperbaric oxygen chamber is further provided with a controller and a micro switch; the micro switch is fixed on one side of the electromagnet, and when the cabin door is closed, the reed on the micro switch is pressed through a fixing bracket; the micro switch controls the on-off of the circuit of the electromagnet through connection with the controller.

[0009] Further, the controller is an MCU single-chip microcomputer.

[0010] Further, a silica gel ring is fixed at the position where the cabin body is in close contact with the cabin door; the silica gel ring is tightly clamped between the cabin body and the cabin door.

[0011] Further, the number of the suction components is two, and the two suction components are respectively arranged at the upper and lower ends of the cabin door.

[0012] Further, a door handle is fixed on the cabin door.

[0013] After adopting the above technical solution, the utility model has the following beneficial effects:

[0014] 1. For the electromagnetic door sucker hyperbaric oxygen chamber of the utility model, when the cabin door is closed, the buffer bump is pressed by the electromagnet and retracts into the buffer hole. Due to the buffering effect of the buffer spring, soft contact can be realized when the electromagnet and the iron block gradually approach. Then, by using the attraction between the energized electromagnet and the iron block, the outer edge of the cabin door can be further closely attached to the cabin body, realizing the sealing of the cabin door and the cabin body. Moreover, the silica gel ring can further improve the sealing effect of the cabin door and the cabin body. When the electromagnet is powered off, under the restoring force of the buffer spring, the electromagnet and the iron block can be separated to realize automatic bouncing open, with simple operation and good use effect.

[0015] 2. For the electromagnetic door sucker hyperbaric oxygen chamber of the utility model, one end of the guide rod is fixedly connected with the cabin body, the other end of the guide rod passes through the mounting plate, and the mounting spring is sleeved outside the guide rod between the mounting plate and the cabin body. When the cabin door is closed, the buffer bump can drive the electromagnet to move slightly backward, realizing soft contact between the iron block on the cabin door and the electromagnet on the cabin body, preventing hard collision between the iron block and the electromagnet when the cabin door is closed forcefully, and improving the service life of the iron block and the electromagnet.

[0016] 3. For the electromagnetic door sucker hyperbaric oxygen chamber of the utility model, when the cabin door is opened, the fixing bracket does not press the reed on the micro switch, and the circuit of the electromagnet is disconnected. When the cabin door is closed, the fixing bracket presses the reed on the micro switch, making the circuit of the electromagnet energized, so that the cabin door and the cabin body are further tightly attracted together, without the need to keep the circuit of the electromagnet always energized, effectively reducing energy consumption.
