Description

Technical Field

[0001] The utility model belongs to the technical field of hydrogen peroxide disinfection, and particularly relates to a dual-purpose hydrogen peroxide disinfection machine. Background Art

[0002] Hydrogen peroxide sterilization technology is widely used for sterilization of biological laboratories, experimental animal rooms, pharmaceutical clean rooms, material transfer rooms and other spaces. This technology uses a hydrogen peroxide generator to flash hydrogen peroxide solution into hydrogen peroxide gas through vaporization and transport it to the space. There are usually two ways of transportation. The first transportation method is to place the generator at a certain point in the sterilization space, and the hydrogen peroxide gas is scattered around through the generator's built-in nozzle. The second transportation method is to reserve two interfaces in the sterilization room, place the disinfection machine outside the sterilization room, connect the disinfection machine and the interface through a pipeline, and transport the hydrogen peroxide gas to the sterilization room.

[0003] Existing units often have multiple clean areas and complex rooms, so the above two methods of hydrogen peroxide delivery are used. Currently, most hydrogen peroxide disinfection machines on the market are single-type, that is, fixed-point space sterilization or pipeline connection sterilization. If all are purchased, the procurement cost will increase, and more disinfection equipment will also take up a larger storage space, resulting in a waste of space, and the daily maintenance of the equipment will also be more cumbersome.

[0025] like Figure 1-4 As shown, a dual-purpose hydrogen peroxide disinfector includes a body 1 of the disinfector, an air inlet 11 is provided at the bottom of the body 1, which can ensure a sterilization environment and improve the airflow circulation efficiency in the room, and an air outlet 12 is provided at the top of the body 1, so that the outlet and the inlet form an airflow circulation in the upper and lower layers, improve the airflow in the space, improve the diffusion efficiency of hydrogen peroxide, and ensure the diffusion uniformity; the air outlet 12 is used to transport the hydrogen peroxide gas inside the body 1 out. The air inlet 11 is connected to the sterilization room through the air inlet pipe 4, and the outlet end of the air inlet pipe 4 is sealed and connected to the air inlet 11 through the first joint assembly 2; the second joint assembly 3 is installed at the air outlet 12, and the second joint assembly 3 is detachably connected to the air inlet end of the diffusion head 7, and the second joint assembly 3 is detachably connected to the air inlet end of the air outlet pipe 5, and the air outlet end of the air outlet pipe 5 is connected to the sterilization room, and the body 1 transports the hydrogen peroxide gas to the inside of the room to be sterilized through the air outlet pipe 5, thereby realizing the dual use of the disinfector. Five nozzles 71 are distributed in a circular array on the top of the diffusion head 7 , and the hydrogen peroxide gas is fully diffused in the space where the body 1 is located through the nozzles 71 .

[0026] Specifically, the first joint assembly 2 and the second joint assembly 3 are both composed of a semicircular first clamping portion 81 and a semicircular second clamping portion 82. The hinged end of the first clamping portion 81 and the hinged end of the second clamping portion 82 both pass through the same fixed shaft 83, so that the first clamping portion 81 and the second clamping portion 82 can both rotate with the fixed shaft 83 as the center, thereby realizing the opening and closing of the first joint assembly 2 and the second joint assembly 3, and one end of the fixed shaft 83 is fixedly connected to the surface of the body 1, so that the first joint assembly 2 and the second joint assembly 3 can rotate relative to the body 1.

[0027] Furthermore, a first through hole is penetrated at the non-hinged end of the first clamping portion 81, and a second through hole is penetrated at the non-hinged end of the second clamping portion 82. The first through hole and the second through hole are coaxially arranged, and a bolt can penetrate the first through hole and the second through hole in sequence and be threadedly connected to the two, thereby realizing the connection and disassembly of the first clamping portion 81 and the second clamping portion 82, and facilitating the connection between the machine body 1 and the air outlet pipe 5 / air inlet pipe 4 / diffuser head 7.

[0028] The first clamping part 81 and the second clamping part 82 are arranged to form a circular structure, and a sealing ring 9 is sleeved inside the circular structure to improve the sealing performance of the body 1 and prevent the leakage of hydrogen peroxide gas. The sealing ring 9 is made of EPDM rubber, which effectively prevents chemical corrosion and improves weather resistance. A clamping ring 91 is fixedly provided at the ports at both ends of the sealing ring 9. The outer diameter of the clamping ring 91 is larger than the outer diameter of the sealing ring 9, so that the clamping ring 91 can clamp the sealing ring 9 on the closed joint assembly, so that the sealing ring 9 is more firmly sleeved in the joint assembly.

[0029] Furthermore, a filter screen, a first filter element, and a second filter element are installed in sequence along the air inlet direction on the inner side of the air inlet 11 of the body 1. The first filter element is glass fiber, and the second filter element is activated carbon. Impurities in the air are adsorbed by the combination of the filter screen, glass fiber, and activated carbon to prevent contamination of hydrogen peroxide gas.

[0030] Universal wheels are provided on the sides of the bottom of the body 1 to facilitate the movement of the sterilizer; a handrail 6 is provided on the top of the body 1 to facilitate the staff to push the sterilizer.

[0031] The working process of the device is described in detail below with reference to the accompanying drawings in the embodiments.

[0032] In the fixed-point space sterilization mode, the staff will pull the handrail 6 to park the sterilizer at a certain fixed position in the space to be sterilized, open the second joint assembly 3, rotate the first clamping part 81 and the second clamping part 82 relative to the fixed shaft 83 away from each other, and set the sealing ring 9 on the air inlet end of the diffusion head 7, and then place the air inlet end of the diffusion head 7 between the first clamping part 81 and the second clamping part 82 of the second joint assembly 3, and align the air inlet of the diffusion head 7 with the air outlet 12 of the sterilizer, close the second joint assembly 3, so that the first clamping part 81 and the second clamping part 82 are close to each other and clamp the air inlet end of the diffusion head 7, and then use bolts to connect the first clamping part 81 and the second clamping part 82, so that the air inlet end of the diffusion head 7 is connected and sealed with the air outlet 12 of the sterilizer. Turn on the sterilizer switch, the hydrogen peroxide gas enters the diffusion head 7 from the air outlet 12, and then sprays out through the nozzle 7, so that the hydrogen peroxide gas is fully transported to the space to be sterilized for disinfection and sterilization.

[0033] In the pipeline connection sterilization mode, the staff will pull the handrail 6 to park the disinfection machine in the room to be sterilized, and use the method of connecting the diffusion head 7 as mentioned above to connect the air outlet 12 of the disinfection machine with the air outlet pipe 5, and the air inlet 11 of the disinfection machine with the air inlet pipe 4, so that the disinfection machine is connected to the sterilization room, turn on the disinfection machine switch, and the hydrogen peroxide gas is transported from the air outlet 12 to the air outlet pipe 5, and then transported to the sterilization room to achieve disinfection of the sterilization room.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
