The utility model discloses an automobile air conditioner air outlet structure relates to the technical field of automobile parts, including the air pipe, and the air outlet grid of air pipe air outlet end installation, air pipe air outlet end is equipped with the magnetic attraction connecting piece for the detachable air outlet grid, the support is installed in the air pipe, the support inner plug has the activated carbon honeycomb board for adsorbing air peculiar smell and the non -woven filter board for filtering air, and the non -woven filter board sets up in activated carbon honeycomb board's air outlet end, the groove on activated carbon honeycomb board installs the liquid storage bottle for storing air air fragrance liquid, the air duct adjusting part of rotatable is arranged in the air pipe, the air outlet grid is connected with the air pipe air outlet end through the magnetic attraction connecting piece, realizes quick dismounting with the magnetic attraction principle, compared with traditional buckle or screw fixed mode, it is more simple and convenient to operate, and the cleaning and maintenance efficiency of air outlet grid has been improved greatly, and the use cost of user has been reduced.

The utility model discloses an unpowered self-purification composite filter material tail water advanced treatment device, and belongs to the technical field of sewage treatment. Comprising a water inlet buffer tank, a drop aeration tank, a constructed wetland and a water outlet well which are sequentially communicated according to a downward stepped structure, a composite filter material reaction tank is further arranged between the drop aeration tank and the constructed wetland, and the composite filter material reaction tank is filled with a composite filter material for adsorbing and degrading pollutants; the drop aeration tank is communicated with the upper part of the composite filter material reaction tank through a water inlet pipeline, and the bottom of the composite filter material reaction tank is communicated with the constructed wetland through a water outlet pipeline. According to the utility model, the composite filter material unit is additionally arranged between the drop aeration unit and the wetland unit in the traditional unpowered treatment device, so that the problem of blockage caused by the fact that the conventional filter material is arranged at the bottom of the constructed wetland is solved, and the whole water purification capacity of the device can be further improved by adjusting the type of the composite filter material and the like.
