The invention discloses an air conditioner air supply device and an air conditioner indoor unit. The air conditioner air supply device comprises an air supply body. The air supply body comprises at least four air guiding bodies with through middles, front openings and rear openings. The air guiding bodies are arranged sequentially from front to back, and front-back-through through air channels are formed in the middles of the air guiding bodies. An air supply gap is formed between every two adjacent air guiding bodies. Heat exchange air enters the through air channels from the air supply gaps. Non-heat exchange air is led into the through air channels from the rear opening of the last level air guiding body. The air supply device further comprises an air guiding body adjusting device which comprises a driving mechanism and a linkage mechanism. Linkage of the multiple middle air guiding bodies located in the middle of all the air guiding bodies arranged sequentially from front to back is achieved through the linkage mechanism. The linkage mechanism is connected with the driving mechanism. The driving mechanism drives the linkage mechanism thus the air supply gaps between the adjacent air guiding bodies is changed dynamically, so that the air supply quantity of the air supply gaps is adjusted, the leading-in quantity of the non-heat exchange air is adjusted, and different requirements of different users are met.

The invention relates to the technical field of desulfurization towers, and discloses a flue gas guiding device for desulfurization towers, which includes a regulating pipe, an air inlet pipe is fixedly connected above the regulating pipe, an air outlet pipe is fixedly connected below the regulating pipe, and an air outlet pipe is fixedly connected below the regulating pipe. The shaft passes through the adjusting tube and is set inside the adjusting tube, the output shaft is provided with a first bevel gear, the inside of the cylinder is provided with a second bevel gear, the second bevel gear is set on a screw, and a screw plate is connected to the screw. There are multiple sets of cones above the screw plate, springs are connected between the cones, extrusion sleeves are arranged on the periphery of the cones, a rope is connected to the extrusion sleeve, and the other end of the rope is connected to the winding wheel. Cavities are formed between the sets of cones. The flue gas guiding device for the desulfurization tower can change the passing area of ​​the flue gas through the up and down movement of the cone, and can change the flow volume of the flue gas per unit time by changing the size of the cavity, and has a variety of ways to adjust the air volume. advantage.

The invention discloses a regulating device for air inlets of an air-assisted sprayer. The regulating device for the air inlets of the air-assisted sprayer comprises a left guide air bellow and a right guide air bellow, wherein the left guide air bellow and the right guide air bellow are fixedly arranged on a chassis of the sprayer. Sprayers and a centrifugal fan are respectively arranged in the air bellows, wherein the sprayers are communicated with a pesticide tank, and the wind direction of the centrifugal fan faces the sprayers; the air inlet of each air bellow is provided with a conical air inlet device; each air inlet device is fixedly provided with a round baffle which is coaxial with the air inlet device, can rotate along the axis and is provided a plurality of scallop holes; and the baffles are respectively controlled by a stepping motor to rotate to realize the change of the air volume of the air inlet of the corresponding air bellow. According to the regulating device for the air inlets of the air-assisted sprayer, the stepping motors are controlled through regulating a manual controller to drive the baffle to move, and therefore, the area of the air inlet of the corresponding guide air bellow is regulated, the change of the air input of the garden air-assisted sprayer is realized, and further, the change of the air volume is realized so as to meet the requirements of different fruiter crown sizes and distances on precision application, the pollution of chemical pesticides to the environment is reduced, and the application level is improved. The regulating device is sensitive in reaction and precise in control.
