Both the first chamber (A1) and the second chamber (A2) respectively are provided with a first one-way valve and a second one-way valve. When the piston rod (33) drives the sealing element (36) into moving reciprocatively, the first chamber (A1) and the second chamber (A2) simultaneously intake air and exhaust air. The dual-chamber dual-action air pump provides doubled air flow rate and doubled efficiency. The glass-wiping robot having the air pump provides suction cups with a vacuum suction force via the air pump, and allows for great air evacuation to be ensured for the suction cups, thus reducing the risks of the glass-wiping robot from falling and thereby being damaged.

Description

双腔双作用气泵及带有该气泵的擦玻璃机器人 技术领域  Double chamber double acting air pump and glass cleaning robot with the same
本发明涉及一种气泵及带有该气泵的擦玻璃机器人， 尤其涉及一种双腔双作用气 泵及带有该气泵的擦玻璃机器人， 属于机械制造技术领域。 背景技术  The invention relates to an air pump and a glass cleaning robot with the same, in particular to a double chamber double acting air pump and a glass cleaning robot with the same, belonging to the technical field of mechanical manufacturing. Background technique
图 1为现有真空气泵的整体结构示意图。 如图 1所示， 现有的真空气泵是通过电 机 100带动通过轴连接的软胶薄膜 200、 300往复运动来实现抽真空的。 由于抽气泵体 积较小， 且电机 100转动一圈， 真空泵单边软胶薄膜 200、 300往复运动一次， 只能够 实现一次抽真空运动。 其缺点是抽气流量过小， 抽真空速度比较慢， 且如果稍微有点 漏气， 真空度就会立即下降。 特别的， 擦玻璃机器人通过该真空气泵为吸盘提供真空 抽吸力时， 若吸盘碰到玻璃表面上的裂缝或凸起而漏气时， 该抽气量过小的真空泵提 供的抽气速度远小于吸盘的漏气速度，易导致擦玻璃机器人跌落损坏或产生安全隐患。 发明内容  1 is a schematic view showing the overall structure of a conventional vacuum air pump. As shown in Fig. 1, the conventional vacuum air pump is driven by the motor 100 to reciprocate the soft film 200, 300 connected through the shaft to achieve vacuuming. Since the suction pump has a small volume and the motor 100 rotates once, the vacuum pump single-sided soft film 200, 300 reciprocates once, and only one vacuuming motion can be realized. The disadvantage is that the pumping flow is too small, the vacuuming speed is relatively slow, and if there is a slight leak, the vacuum will drop immediately. In particular, when the vacuum cleaner supplies the vacuum suction force to the suction cup by the vacuum pump, if the suction cup hits a crack or a protrusion on the surface of the glass and leaks, the vacuum pump provided by the vacuum pump has a pumping speed that is much smaller than that of the vacuum pump. The air leakage speed of the suction cup may easily cause the glass-washing robot to fall or be damaged or pose a safety hazard. Summary of the invention
