Shared electric sanitation vehicle
The invention relates to the technical field of vehicles and particularly relates to a shared electric sanitation vehicle. The device comprises a water tank arranged on a vehicle body, wherein a firstthreaded pipe is arranged on an upper surface of the water tank, an upper cover is arranged on the first threaded pipe, a through hole is formed in an upper surface of the upper cover, a fixing pipeis arranged in the through hole, external threads are arranged on an outer surface of a bottom end of the fixing pipe, a second threaded pipe is arranged at a bottom end of the fixing pipe and locatedat the external threads, a constant-pressure cylinder is tightly welded to a bottom end of the second threaded pipe, and a thin spring is arranged in the constant-pressure cylinder. The device is advantaged in that when the air pressure in the water tank is low, when the external air pressure is large, a sealing block is subjected to downward pressure, the sealing block compresses a thin spring and moves into the constant-pressure cylinder, so an air inlet hole in the constant-pressure cylinder is communicated with the fixing pipe, air pressure difference between the interior and the exteriorof a water tank body is balanced, the situation that the water tank is extruded and deformed due to the pressure difference is prevented, and a problem that the electric sanitation vehicle is inconvenient to balance the air pressure of the water tank and the exterior is solved.
本发明涉及车辆技术领域，尤其为一种共享电动环卫车，包括设置于车体上的水箱，水箱的上表面设有第一螺纹管，第一螺纹管上设有上盖，上盖的上表面设有通孔，通孔内设有固定管，固定管底端外表面设有外螺纹，固定管的底端位于外螺纹的位置处设有第二螺纹管，第二螺纹管的底端紧密焊接有恒压筒，恒压筒内设有细弹簧。该共享电动环卫车，当水箱内的气压较低，外界气压较大时，密封块受到一个向下的压力，密封块压缩细弹簧并运动至恒压筒内，使得恒压筒上的进气孔与固定管连通，以此便实现平衡水箱箱体内和外界的气压差，防止水箱因压强差而受挤压变形的状况出现，解决电动环卫车不便于平衡水箱与外界气压的问题。
