The invention is further illustrated by the following figures and examples, which are not to be construed as limiting the invention.
The embodiment of the invention comprises the following steps: the utility model provides an assembly type structure wall body that possesses air purification function, as shown in fig. 1-5, including the wallboard 1 that can assemble, cavity 2 has been seted up to the inside of wallboard 1, it is connected with flabellum 4 to rotate through bull stick 3 respectively on the outer wall of wallboard 1, the other end of bull stick 3 stretches into in cavity 2 and is connected with and presses the board 5, be equipped with the backup pad in the cavity 2 of clamp plate 5 below, be provided with extrusion bag 6 in the cavity 2 of backup pad top, set up air inlet tank 7 on the wallboard 1 outer wall that extrusion bag 6 one side corresponds, air inlet tank 7 is linked together with extrusion bag 6 is inside, be equipped with the check valve 8 that supplies external gas to flow into in the extrusion bag 6 in the air inlet tank 7, seted up air-out groove 9 on the wallboard 1 inner wall that the backup pad below corresponds, extrusion bag 6 bottom is connected with stretches out the tuber pipe 11 of backup pad bottom, be equipped with No. two check valve 12 that supply the gas outflow in the extrusion bag 6 on the tuber pipe 11.
After the assembly type building wall body in the prior art is temporarily assembled and molded, because the formaldehyde pollution of the internal building materials or furniture is serious, the assembly type building wall body cannot play a role in air purification, indoor air can be purified only by continuous work of an air interchanger, and the assembly type building wall body is not environment-friendly and energy-saving. When the wall plate 1 is assembled, one surface of the wall plate 1 with the fan blades 4 faces outdoors to be assembled, when wind exists outside, the fan blades 4 rotate and drive the pressing plate 5 to intermittently extrude the extrusion bag 6, so that the extrusion bag 6 can continuously suck fresh outside air and continuously discharge the fresh outside air into the cavity 2 at the bottom end of the supporting plate under the matching of the two one-way valves in the back-and-forth extrusion process, then the air in the cavity 2 at the bottom end of the supporting plate flows out of the air outlet groove 9, so that the air can be continuously exchanged indoors by using the wind force of the outside, the indoor air is effectively purified, when large sundries such as plastic bags flow to the air inlet groove 7, the rotating fan blades 4 can break and throw the sundries away, and the condition that the air inlet groove 7 is blocked by foreign objects to cause the wall body 1 to work to fail is reduced.
Be equipped with filter screen 10 in the air-out groove 9, can intercept the impurity in the blowout gas through filter screen 10.
The outer surface of the extrusion bag 6 is sleeved with a heat absorption bag 13, the shapes of the side walls of the extrusion bag 6 and the heat absorption bag 13 are respectively set into a wave shape, a heat conduction plate 14 is embedded and installed on the outer wall of the wall plate 1 corresponding to one side of the heat absorption bag 13, and the heat absorption bag 13 is attached to the inner surface of the heat conduction plate 14. When the wind power is low in sunny weather, the heat conducting plate 14 can transfer heat to the heat absorbing bag 13 after absorbing heat, so that the gas in the heat absorbing bag is heated and then expands, and the extrusion bag 6 is driven to synchronously expand, thereby increasing the subsequent exhaust and suction amount of the extrusion bag 6, and improving the indoor ventilation effect by increasing the ventilation amount of the extrusion bag 6 when the wind power is low. When the temperature is low in winter, the heat conducting plate 14 can transmit heat to the heat absorbing bag 13 at the moment, and the situation that the elasticity of the heat absorbing bag 13 and the extrusion bag 6 is weakened due to low temperature is reduced.
And the inner surface of the extrusion bag 6 is jointed with a heat-insulating layer. When the weather is hot, the heat absorption bag 13 can transmit heat to the extrusion bag 6, the temperature of the gas in the extrusion bag 6 is raised and then the gas is sprayed into the chamber, the chamber is hotter, the arranged heat insulation layer can reduce the overhigh temperature of the gas in the extrusion bag 6 in summer, the sprayed gas in the extrusion bag 6 is cooler, and meanwhile, the temperature of the surface of the extrusion bag 6 is raised and the better elasticity is kept when the extrusion bag 6 is in winter.

Link firmly in the cavity 2 that 3 inner corresponds of bull stick has the connecting block 18 of laminating mutually with 3 tip of bull stick, be equipped with the transport strip 19 that extends to 6 tops of squeeze bag on the terminal surface that connecting block 18 is close to bull stick 3, 3 the inner flowback groove 20 that extends to 5 free ends of clamp plate is seted up to bull stick, and be equipped with in the flowback groove 20 of 3 tip of bull stick and extend to 5 inside backward flow strips 21 of clamp plate, the free end of clamp plate 5 rotates and is connected with spin 22, it is made by water-absorbing material with backward flow strips 21 to carry strips 19, load lubricating oil in the flowback groove 20 at spin 22 top. Bull stick 3 can drive spin 22 when rotating and roll at 6 tops of extrusion bag, compress extrusion bag 6, reduce the resistance and the wearing and tearing of 5 tip of clamp plate and pressure bag simultaneously, and spin 22 is when rolling, lubricating oil in return-flow tank 20 can constantly ooze, thereby can play lubricated effect to spin 22, and the lubricating oil that oozes can convey to return-flow strip 21 through carrying strip 19, and return-flow strip 21 can rotate under the drive of bull stick 3, and throw away its inside lubricating oil to return-flow tank 20 in, thereby make lubricating oil can effectual recovery recycle.
Be connected with shutoff board 23 in the inside backward flow groove 20 of clamp plate 5, a plurality of funnel shape grooves 24 have been seted up to shutoff board 23 inside, and the notch in funnel shape groove 24 is dwindled to the one end of keeping away from bull stick 3 by the one end that is close to bull stick 3 gradually, is connected with shutoff ball 25 through the elastic rope on the shutoff board 23 that the one end that bull stick 3 was kept away from to funnel shape groove 24 corresponds. When bull stick 3 rotates, can make the shutoff ball 25 keep away from funnel-shaped groove 24 under the effect of centrifugal force, the funnel-shaped groove 24 that sets up simultaneously can make the lubricating oil that backward flow strip 21 was thrown away easily flow in, and the lubricating oil that is located the backward flow groove 20 of spin 22 department is difficult to follow the narrower tip of funnel-shaped groove 24 and flows out, thereby reach backward flow groove 20 and carry out the effect of effective storage to throwing away lubricating oil, reduce clamp plate 5 at the rotation in-process, lubricating oil contacts and the absorptive condition with backward flow strip 21 again, the recovery effect of backward flow strip 21 and transport strip 19 to lubricating oil has been improved, simultaneously after bull stick 3 stop work, shutoff ball 25 carries out the shutoff to funnel-shaped groove 24 under the effect of elasticity rope, further reduce the lubricating oil that throws away in the backward flow groove 20 again with the condition of backward flow strip 21 contact.
