Description

Surface cleaning device Technical Field The application belongs to the technical field of cleaning equipment, and particularly provides a surface cleaning device. Background Currently, surface cleaning apparatuses capable of simultaneously sucking liquid and solid dirt on a surface to be cleaned generally include a dirt suction port, a dirt collection tub, and a suction source assembly capable of sucking dirt on the surface to be cleaned into the dirt collection tub by a suction airflow. Because the suction source assembly requires exhaust to continuously generate suction, the surface cleaning apparatus may also be provided with an exhaust vent to remove air. In the prior art, in order to simplify the structure and be beautiful, part of the surface cleaning device can directly set up the rear side at the position of the suction source component with the air outlet, so that not only is noise big, but also the air flow is led to be directly discharged to the user, and the discharged air flow can carry part of bacteria and water vapor, so that the problem of sanitation exists and the user experience is poor. And part of the surface cleaning device enables the air flow to be discharged to the inside of the machine body of the surface cleaning device and then discharged from other positions, and although the air flow cannot be discharged to a user, bacteria and water vapor carried by the air flow can be accumulated in the machine body, so that the use safety of electric elements in the machine body is easily affected, and the inside of the machine body is not cleaned well. Disclosure of Invention In order to solve the above problems in the prior art, that is, in order to solve the problem of poor air exhaust mode of the existing surface cleaning device, the application provides a surface cleaning device, which comprises a machine body and a cleaning head pivotally connected with the machine body, wherein a dirt collecting barrel and a suction source assembly are arranged on the machine body, the dirt collecting barrel is provided with a dirt collecting cavity, the dirt collecting cavity is respectively communicated with the suction source assembly and a dirt suction port on the cleaning head, an inlet, an outlet and an air exhaust cavity communicated with the inlet and the outlet are also arranged on the dirt collecting barrel, and an air outlet of the suction source assembly is communicated with the inlet of the dirt collecting barrel, so that air flow exhausted by the suction source assembly enters the air exhaust cavity from the air outlet and is exhausted from the outlet of the air exhaust cavity. Preferably, a closed exhaust channel is formed in the exhaust cavity between the inlet and the outlet of the dirt collecting barrel. Preferably, the exhaust passage is at least partially disposed around the dirt collection chamber. Preferably, the exhaust passage is one or more.
