In one embodiment, the deformable tube 510 is a support-free universal bamboo joint tube, and can be bent or twisted at will while supporting the gas-collecting hood 520, so as to adjust the orientation and the horizontal height of the input end of the gas-collecting hood 520 and the distance between the input end and the interrogation site, so that the air at the interrogation site can be absorbed by the gas-collecting hood 520 to the maximum extent, thereby improving the applicability and reliability of the air sterilizer 10 and further improving the indoor air purification efficiency. In one embodiment, the gas-collecting hood 520 has a trumpet-shaped structure. By arranging the gas collecting channel 520 in a trumpet-shaped structure, the air inlet area of the gas collecting channel 520 is increased, and the resistance of the inner surface of the gas collecting channel 520 to the air flow is reduced, so that the air inlet amount in the housing 100 is increased, and the air to be purified can be rapidly introduced into the purifying chamber 110.

It should be noted that, in the actual production, the air sterilizer 10 may be made into a sterilizer with a smaller size so as to be placed on the table of an office or hung on a wall, and of course, the size of the air sterilizer 10 may be increased and attached to a dental chair so as to absorb tooth dust generated in the dental operation and gas exhaled from the oral cavity of the patient during the dental operation, thereby avoiding the threat that the gas exhaled from the patient may cause to the medical staff and improving the reliability of the dental operation. In addition, the air sterilizer 10 may be attached to a plurality of apparatuses for oral treatment and interrogation, and the size of the air sterilizer may be adjusted to be suitable for the medical apparatuses, so as to improve the safety of treatment and interrogation, which will not be described herein.
