The invention has the beneficial effects that:

(1) according to the movable air purification and disinfection machine, air can enter the cabinet body through the filtering structure and then is subjected to various treatments, impurities in the air are left in the air purification machine, so that the air becomes purer, a user can well clean dust inside the air through the cleaning structure, the machine is prevented from being mounted back after being detached and a dust-attached net is taken out for cleaning, the human respiratory tract can be well protected through the cleaning structure, and a large amount of dust is prevented from entering the human respiratory tract when the dust is cleaned, namely: firstly, the user starts the device, the driving component inside the device is started, thereby driving the fan blades, sucking air from the cover plate, then the air enters the filter cotton again, the air enters the air channel after being filtered by the filter screen, then the air is filtered by the decomposition plate, the germicidal lamp tube and the carbon filter plate, thereby the other side of the cabinet body is discharged, and the air can be heated by the control heating plate, and the device is also provided with a universal wheel, the device can be moved very conveniently, when a large amount of dust is attached to the dust screen, the user can drive the second gear fixedly connected with the user by rotating the rotating knob, so that the two first gears which are meshed with each other are driven, thereby the side of the cleaning rod with the brush hair is downward, then the user slides the carriage again, so that the carriage is positioned at the top of the chute, and then the brush hair dust screen is abutted, the user presses the knob again afterwards, prevents that the knob from rotating when sliding the balladeur train, and the user slides the balladeur train downwards afterwards, can brush the dust on the dust screen down to because the inside bottom of dust rack is the triangle-shaped, thereby can be fine prevent a large amount of dust cards between dust rack and dust screen.

(2) According to the mobile air purification and disinfection machine, the dust can be well collected in the storage box through the storage structure, the dust is prevented from falling to the ground or being re-introduced into the machine after the machine is started for use next time due to the fact that the dust falls into the machine, the dust and floccules attached to the cleaning structure can be well extracted through the removing structure, and the dust is prevented from being re-introduced into the machine during next cleaning, namely: after the dust when brushing down, the dust can drop to on the receiver, sliding connection's bolt on operating personnel can the sliding baffle, thereby relieve the conflict state of bolt and receiver, the user pulls the handle again afterwards, take out the receiver, fall the dust on the receiver can, but can have not few dust on the brush hair when clearing up, operating personnel rotates the turn button right towards the turn button this moment, thereby two clean pole each other are opposite direction rotation, and rotate the in-process again and can conflict the rejection pole of fixing on the receiver, the pole of rejecting of a set of and evenly distributed on the receiver can be fine will twine in the brush hair dust and the floccule drag to in the receiver, still can contradict thinner rejection needle for the brush hair afterwards, thereby can be better clean for the brush hair.

(3) According to the mobile air purification and disinfection machine, the placing structure and the foot stand structure can be used for supporting the machine well when the machine needs to be prevented in one place for a long time, so that the machine is prevented from moving due to operation or personnel collision, and the device can be well fixed in one place and also can be well moved through the matching of the adjusting state of the placing structure and the filtering structure, namely: when the air purifier is carried to a position needing to work for a long time, one corner of the cabinet body can be lifted in sequence, the second sliding sleeve is firstly slid downwards, because the second sliding sleeve is connected with the clamping block in a sliding manner, one end of the clamping block is toothed, the limiting groove is also toothed, and the limiting groove and the bevel edge of the clamping block are downward, so that the second sliding sleeve is not hindered from sliding downwards, when a user excessively pulls the second sliding sleeve to cause one corner of the cabinet body to be higher than other corners, the user can engage two exposed parts on the second sliding sleeve, so that the conflict state of the clamping block in the limiting groove is relieved, the second sliding sleeve can be slid upwards, after the positions of the four second sliding sleeves are adjusted, the user only needs to press the button, the internal foot stool can be popped out from the second sliding sleeve, because when the button is pressed, the button can conflict with the rotating block, so that the other end of the rotating block and the fixed block which conflicts with the rotating block can slide towards the direction deviating from the foot stool, the conflict state that the fixed block passes through fixed slot and foot rest is relieved in the feasible foot rest to the pulling force of the second torsional spring that can receive and be equipped with between the second sliding sleeve pops out the second sliding sleeve and supports ground.
