Problems solved by technology

The disadvantage is that the pumping flow rate is too small, the vacuuming speed is relatively slow, and if there is a slight air leak, the vacuum degree will drop immediately
In particular, when the glass-wiping robot provides vacuum suction force for the suction cup through the vacuum air pump, if the suction cup encounters a crack or a protrusion on the glass surface and leaks air, the vacuum pump with too small suction capacity will provide a much slower suction speed than the vacuum pump. The air leakage speed of the suction cup may easily cause the glass-cleaning robot to fall and damage or cause safety hazards

Embodiment 1

[0032] The invention provides a double-cavity double-acting air pump. Generally speaking, the air pump includes a cylinder, a driving device connected to the cylinder and a piston. The driving device drives the piston to reciprocate in the cylinder through a transmission device. Connected seal, the seal divides the cylinder into a first cavity and a second cavity, the first cavity and the second cavity are respectively equipped with a first one-way valve and a second one-way valve, and the piston rod drives the seal During the reciprocating movement of the parts, the first cavity and the second cavity are simultaneously pumped and exhausted. figure 2 It is an exploded view of the overall structure of the present invention; image 3 It is a cross-sectional view of the air pump body and cylinders on both sides of the present invention. Such as figure 2 and combine image 3 As shown, specifically, the double-cavity double-acting air pump provided in this embodiment includes ...

Embodiment 2

[0044] The double-chamber double-acting air pump provided in this embodiment has basically the same structure as that of the first embodiment, except that the structure of the transmission device is different from that of the first embodiment. Figure 9 It is a structural schematic diagram of the eccentric shaft transmission device of the second embodiment of the present invention. Such as Figure 9 As shown, the transmission device of the air pump in this embodiment is an eccentric shaft device sleeved on the output shaft of the motor, and the end of the piston rod 33 is sleeved on the eccentric shaft 51 . In order to balance the eccentric force generated by the eccentric shaft 51 during the rotation process, an air pump counterweight ring 52 and other components are usually arranged on the output shaft of the motor.

[0045] For other technical features in this embodiment, reference may be made to Embodiment 1, which will not be repeated here.

Embodiment 3

[0047] The structure of the double-chamber double-acting air pump provided in this embodiment is basically the same as that of Embodiment 1, and the difference between the two also lies in the structure of the transmission device. Figure 10 It is a structural schematic diagram of the transmission device of the three eccentric wheel mechanisms in the embodiment of the present invention. Such as Figure 10 As shown, the transmission device of the air pump in this embodiment is an eccentric wheel mechanism connected to the output shaft of the motor. The eccentric wheel mechanism includes an eccentric wheel 61 fixed on the output shaft, and an annular limit groove is provided on one side surface of the eccentric wheel 61. 611; the end of the piston rod 33 of each piston air pump assembly is provided with a roller 331, the roller 331 is embedded in the annular limit groove 611, the output shaft drives the eccentric wheel 61 to rotate, and the roller 331 is in the annular limit gro...

Abstract

A double-cavity double-acting air pump and a glass-wiping robot with the air pump. The air pump includes a cylinder, a drive device connected to the cylinder and a piston. The drive device drives the piston to reciprocate in the cylinder through a transmission device. The rod is fixedly connected to the seal, and the seal divides the cylinder into a first chamber (A1) and a second chamber (A2). The first chamber and the second chamber are respectively equipped with a first one-way valve and a second chamber. In the one-way valve, during the reciprocating movement of the sealing member driven by the piston rod, the first cavity and the second cavity are simultaneously pumped and exhausted. The invention has a simple and compact structure, doubles the flow rate, and doubles the efficiency; the glass-wiping robot provides vacuum suction force for the suction cup through the vacuum air pump, even when the suction cup encounters cracks or protrusions on the glass surface and leaks air, It can also ensure good suction of the suction cup, reduce the risk of the glass-wiping robot falling and being damaged, and eliminate potential safety hazards.

Description

technical field [0001] The invention relates to an air pump and a glass-wiping robot equipped with the air pump, in particular to a double-cavity double-action air pump and a glass-wiping robot equipped with the air pump, belonging to the technical field of mechanical manufacturing. Background technique [0002] figure 1 It is a schematic diagram of the overall structure of the existing vacuum air pump. Such as figure 1 As shown, in the existing vacuum air pump, the motor 100 drives the soft rubber film 200, 300 connected by the shaft to reciprocate to realize vacuuming. Because the volume of the air pump is small, and the motor 100 rotates once, the unilateral soft rubber film 200, 300 of the vacuum pump reciprocates once, and only one vacuum pumping motion can be realized. The disadvantage is that the pumping flow rate is too small, the vacuuming speed is relatively slow, and if there is a slight air leak, the vacuum degree will drop immediately. In particular, when th...
