DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0024] Please refer to Figures 1-6 ​As shown in the figure, a multifunctional suction cup for a dust collection vehicle includes a suction cup bin 1, a dust collection hose 4, a blockage prevention and convenient cleaning assembly 2, and an auxiliary blockage assembly 3. One end of the dust collection hose 4 is fixedly installed between the inner and outer walls of the suction cup bin 1. The blockage prevention and convenient cleaning assembly 2 is arranged inside the suction cup bin 1. The auxiliary blockage assembly 3 is installed outside the blockage prevention and convenient cleaning assembly 2. The blockage prevention and convenient cleaning assembly 2 can block and store small stones to increase the capacity of the dust bag. The auxiliary blockage assembly 3 can block large stones to reduce the blockage of the suction cup bin 1 by large stones, making the overall practicality better.

[0025] As shown in the figure, Figures 2-6 The blockage prevention and convenient cleaning assembly 2 includes a moving shell 201. A plug rod 202 is movably arranged between the inner and outer walls of the suction cup bin 1. A fixed side plate 203 is fixedly installed on the sidewall of the suction cup bin 1. A bidirectional screw rod 204 is rotatably connected between the inner and outer walls of the fixed side plate 203. An L-shaped plate 205 is screwed on the outer surface of the bidirectional screw rod 204. One end of the L-shaped plate 205 is fixedly connected to the outer surface of the plug rod 202. A small motor 206 is fixedly installed on the outer surface of the fixed side plate 203.

The blockage prevention and convenient cleaning assembly 2 further includes a concave plate 207 arranged inside the suction cup bin 1. The sidewall of the moving shell 201 and the concave plate 207 are both provided with a slot. The plug rod 202 is inserted into the slot. A small dust suction hole is formed in the suction cup bin 1. A middle dust suction hole is formed in the concave plate 207. A large dust suction hole is formed in the moving shell 201. The user connects the dust collection hose 4 with the dust collection vehicle and turns on the dust collection device inside the dust collection vehicle. When the dust collection device is turned on, the suction cup bin 1 can absorb dust on the ground. The fine dust finally falls into the dust bag through the suction cup bin 1 and the dust collection hose 4. When the suction cup bin 1 sucks in stones, the concave plate 207 blocks small stones to reduce the blockage of the suction cup bin 1 by stones. When there are residual stones in the suction cup bin 1, the small motor 206 is turned on to drive the bidirectional screw rod 204 to rotate. The rotation of the bidirectional screw rod 204 moves the L-shaped plate 205. The movement of the L-shaped plate 205 causes the plug rod 202 to move out of the slot, so that the moving shell 201 and the concave plate 207 can be detached for the user to clean the stones inside the suction cup bin 1, thereby avoiding the problem that the suction cup bin in the existing device is difficult to disassemble, making it difficult to clean the stones and affecting the suction force of the dust collection vehicle.
