Description

Technical Field

[0001] This utility model relates to the field of hyperbaric oxygen chamber technology, and in particular to an air purification and filtration device for hyperbaric oxygen chambers. Background Technology

[0002] A hyperbaric oxygen chamber is a specialized medical device for hyperbaric oxygen therapy. Depending on the pressurizing medium, it is divided into two types: air hyperbaric chamber and pure oxygen hyperbaric chamber. Hyperbaric oxygen chambers have a wide range of applications and are mainly used clinically for the treatment of anaerobic bacterial infections, carbon monoxide poisoning, air embolism, decompression sickness, hypoxic-ischemic encephalopathy, traumatic brain injury, and cerebrovascular diseases.

[0003] Hyperbaric oxygen chambers are isolated from the outside environment during operation. When patients enter, the germs they carry can easily spread into the air inside the chamber. Existing air purification equipment can only purify dust in the air and is unable to kill bacteria. Because hyperbaric oxygen chambers are sealed, conventionally spraying alcohol into the chamber for sterilization results in a persistent alcohol odor, which is inconvenient. Therefore, there is an urgent need to develop an air purification and filtration device for hyperbaric oxygen chambers that is convenient for sterilizing the air and can also adsorb dust and alcohol after sterilization, thus achieving a better purification effect. This would overcome the shortcomings of current practical applications and meet current needs. Utility Model Content

[0004] The purpose of this invention is to provide an air purification and filtration device for hyperbaric oxygen chambers to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The air purification and filtration device for a hyperbaric oxygen chamber includes a chassis, a disinfection chamber, a circulating air pump, a spray disinfection mechanism, a spiral tube, an adsorption box, a pull-out mesh box, an air outlet pipe, and guide plates. The chassis houses the disinfection chamber, the circulating air pump, and the adsorption box. The inlet end of the circulating air pump is connected to an inlet pipe extending to the outside of the chassis, and the outlet end of the circulating air pump is inserted into the disinfection chamber. The spray disinfection mechanism, extending into the disinfection chamber, is installed inside the chassis. A spiral tube is located on the right side of the disinfection chamber, with its upper end connected to the disinfection chamber and its lower end connected to the adsorption box. Multiple guide plates are fixed on both the left and right sides inside the adsorption box, forming airflow channels within the adsorption box. The top of the adsorption box is equipped with an exhaust pipe extending to the outside of the casing. Multiple pull-out mesh boxes, filled with activated carbon, are detachably installed on the right side of the adsorption box. The spraying disinfection mechanism includes an alcohol storage tank, a water pump, a conduit, a diversion pipe, atomizing nozzles, and a rotating mechanism. The alcohol storage tank and water pump are both fixed to the top of the casing. The water pump inlet is connected to the alcohol storage tank, and the water pump outlet is fixedly connected to a conduit. The diversion pipe is rotatably connected to the disinfection box. Multiple atomizing nozzles are installed at the bottom of the diversion pipe, and the upper end of the diversion pipe is inserted into and rotatably connected to the conduit. A rotating mechanism for driving the diversion pipe to rotate is installed on the disinfection box.

[0007] Preferably, the rotating mechanism includes a drive motor, a first gear, and a second gear. The drive motor is fixed to the top of the disinfection box, and the first gear is fixed on the output shaft of the drive motor. A second gear is provided on one side of the first gear to mesh with it, and the second gear is fixedly installed on the diversion pipe.

[0008] Preferably, the alcohol storage box is made of transparent material, and a plug is detachably installed on the top of the alcohol storage box.

[0009] Preferably, the top of the chassis is equipped with a motor switch button, an air pump switch button, and a water pump switch button. The circulating air pump is electrically connected to the air pump switch button via a wire, the water pump is electrically connected to the water pump switch button via a wire, and the drive motor is electrically connected to the motor switch button via a wire.

[0010] Preferably, the left side of the pull-out mesh box is provided with a slot for locking onto the guide plate.

[0011] The beneficial effects of this utility model are as follows: When using this air purification and filtration device in a hyperbaric oxygen chamber, the machine is placed inside the hyperbaric oxygen chamber. A circulating air pump draws air from the chamber and delivers it to the disinfection chamber. A water pump draws alcohol from the alcohol storage tank and delivers it to the distribution pipe. Alcohol is sprayed through atomizing nozzles and mixed with the airflow. Simultaneously, a drive motor rotates the first and second gears. The rotation of the second gear drives the distribution pipe and atomizing nozzles, ensuring more thorough contact between the alcohol spray and the airflow. This kills germs in the airflow with the alcohol. The airflow then flows through a spiral tube into the adsorption box. The spiral tube design increases the airflow time, allowing for longer contact between the airflow and alcohol, facilitating sterilization. The airflow in the adsorption box then flows upward along the airflow channel formed by multiple guide plates. During this process, the airflow repeatedly contacts the activated carbon in multiple pull-out mesh boxes, adsorbing dust and alcohol from the airflow. Finally, clean air is discharged from the outlet pipe back into the hyperbaric oxygen chamber. In summary, this invention provides convenient air sterilization, and after sterilization, it adsorbs dust and alcohol from the air, resulting in better purification. Attached Figure Description

An outlet pipe 10 extending to the outside of the casing 1 is installed on the top of the adsorption box 8. Multiple pull-out mesh boxes 9 are detachably installed on the right side of the adsorption box 8 and filled with activated carbon. A slot 901 for engaging with the guide plates 11 is provided on the left side of the pull-out mesh box 9. The spray disinfection mechanism 6 includes: an alcohol storage tank 601, a water pump 602, a conduit 603, a diverter pipe 604, an atomizing nozzle 605, and a rotating mechanism 606. The alcohol storage tank 601 is made of transparent material. To clearly see the alcohol content inside, a plug 6011 is detachably installed on the top of the alcohol storage tank 601. Removing the plug 6011 allows for the replenishment of alcohol into the storage tank 601. Both the alcohol storage tank 601 and the water pump 602 are fixed to the top of the casing 1. The inlet of the water pump 602 is connected to the alcohol storage tank 601, and the outlet of the water pump 602 is fixedly connected to a conduit 603. A branch pipe 604 is rotatably connected to the disinfection box 4. Multiple atomizing nozzles 605 are installed at the bottom of the branch pipe 604. The upper end of the branch pipe 604 is inserted into and rotatably connected to the conduit 603. The disinfection box 4 is equipped with a rotating mechanism 606 for rotating the branch pipe 604. Mechanism 606 includes: drive motor 6061, first gear 6062 and second gear 6063. Drive motor 6061 is fixed to the top of disinfection chamber 4. First gear 6062 is fixed on the output shaft of drive motor 6061. Second gear 6063 is provided on one side of first gear 6062 and meshes with it. Second gear 6063 is fixedly installed on diverter pipe 604. In use, the machine box 1 is placed in the hyperbaric oxygen chamber. Air is drawn from the hyperbaric oxygen chamber by circulating air pump 5 and delivered to disinfection chamber 4. Alcohol is drawn from alcohol storage tank 601 by water pump 602 and delivered to diverter pipe 604. Alcohol spray is sprayed out through atomizing nozzle 605 and mixed with airflow.

[0023] The front of the chassis 1 is connected to the door 2 via a hinge, and the bottom of the chassis 1 is equipped with multiple casters 3.

[0025] Working principle: When using this air purification and filtration device in a hyperbaric oxygen chamber, the casing 1 is placed inside the chamber. The circulating air pump 5 draws air from the chamber and delivers it to the disinfection box 4. The water pump 602 draws alcohol from the alcohol storage tank 601 and delivers it to the distribution pipe 604. The alcohol is then sprayed through the atomizing nozzle 605, mixing with the airflow. Simultaneously, the drive motor 6061 drives the first gear 6062 and the second gear 6063 to rotate. The rotation of the second gear 6063 drives the distribution pipe 604 and the atomizing nozzle 605 to rotate, thus atomizing the nozzle... The alcohol spray from 605 has more thorough contact with the airflow, killing germs in the airflow with alcohol. Then, the airflow flows through the spiral tube 7 into the adsorption box 8. The spiral tube 7 increases the airflow time, allowing for a longer contact time between the airflow and alcohol, which facilitates sterilization. Then, the airflow in the adsorption box 8 flows upward along the airflow channel formed by multiple guide plates 11. During this process, the airflow comes into contact with the activated carbon in multiple pull-out mesh boxes 9 multiple times, and the activated carbon adsorbs the dust and alcohol in the airflow. Finally, the clean air is discharged from the exhaust pipe 10 into the hyperbaric oxygen chamber.
