This invention relates to the field of sampling device technology, and in particular to a throat swab sampling robot and sampling method. The throat swab sampling robot includes a housing, an actuator, and a user operating unit. The actuator is housed within the housing, and the user operating unit includes a ventilation hood. The spaces within the ventilation hood and the housing are independently configured, connected by a perforation. The ventilation hood is equipped with an exhaust device to maintain a negative pressure environment and a collection port for extending a swab. During sampling, the user's mouth needs to be aligned with the collection port. The actuator picks up the swab and moves it to the collection port for sampling. The exhaust device maintains a negative pressure environment within the ventilation hood, expelling aerosols exhaled by the user and preventing contamination of the actuator. The independent configuration of the ventilation hood and housing space reduces the likelihood of contamination of the actuator by placing the sampling process and the actuator in separate spaces.
