It can kill most microorganisms, including bacteria, fungi, mycobacteria, viruses and bacterial spores, achieving high-level disinfection to sterilization. The disinfection activity is not affected by pH value, and these microorganisms are not easy to develop resistance.
[0003] Chlorine dioxide gas is unstable and easily reduced, exploded, and photolyzed. Therefore, chlorine dioxide gas is mostly obtained by on-site preparation before being used for disinfection. Many chlorine dioxide gas disinfection devices on the market currently use a single beaker reaction chamber. Due to the limitations of reaction conditions, the amount of reagents involved in a single reaction cannot be too large, resulting in a limited total amount of chlorine dioxide gas produced. Other chlorine dioxide gas disinfection devices cannot achieve a good sealing effect, and after the reaction is completed, they cannot realize the functions of autonomous cleaning and drainage. They also need to be cleaned manually, which is time-consuming and labor-intensive.
[0004] Therefore, it is necessary to provide a reaction chamber of a gas chlorine dioxide disinfection device, which can achieve a better sealing effect and automatically complete the cleaning and drainage procedures after the reaction is completed. Utility Model Content

The plastic claw is installed between the first glass tube joint and the rubber sleeve. By rotating and tightening the second glass tube joint, the pre-tightening force is transmitted to the plastic claw through the rubber sleeve. The plastic claw passes through the spherical surface of the first glass tube joint, so that the claws of the plastic claw are compressed toward the center and squeezed onto the rubber sleeve, and then the rubber sleeve can tightly hold the flushing glass tube or the water absorbing glass tube, which can prevent the flushing glass tube or the water absorbing glass tube from rotating or moving in and out.

The heating to produce chlorine dioxide gas can be done by using the first glass and the second glass to react separately or simultaneously.
[0019] The working principle and process of cleaning the reaction residue of the gas chlorine dioxide disinfection device of the utility model are as follows:
[0020] The first glass and / or the second glass have a flushing glass tube and a water absorbing glass tube respectively. When flushing, water is injected into the glass through the parts connected to the flushing glass tubes. The position of the end of the flushing glass tube deviates from the center of the glass, which will cause the incoming water to generate vortexes, stir the reaction residues inside, and form a better fusion with the water. When the height sensed by the liquid level sensor is reached, the water injection is stopped, and the heating sleeve is also heated at this time to make the residues dissolve better; after a certain period of full fusion, the drainage work begins, and the drainage is mainly discharged through the parts connected to the water absorbing glass tube for cleaning.
