Description

Technical Field

[0001] The utility model relates to the technical field of cleaning machines, in particular to a liquid supply device for cleaning machines. Background Art

[0002] The cleaning machine is used to flush and filter the pollutants generated or invaded during the manufacturing, assembly, use and maintenance of the hydraulic system; it can also be used for regular maintenance and filtration of working oil to improve cleanliness, avoid or reduce failures caused by contamination, thereby ensuring the high performance, high reliability and long life of hydraulic system equipment.

[0003] A cleaning machine generally provides cleaning liquid through an external liquid supply tank. Generally, the liquid supply tank does not have a reminder function, resulting in the user having to refill the cleaning liquid after the cleaning liquid in the liquid supply tank is used up, causing the cleaning work to be interrupted, seriously affecting the cleaning work efficiency. Herein, we propose a liquid supply tank that automatically replenishes the cleaning liquid, and replenishes the cleaning liquid only by replacing the liquid supply tank, preventing the work from being interrupted due to replenishment after the liquid in the external liquid supply device is exhausted, and the replenishment of the cleaning liquid is more convenient. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model cooperates with the air inlet, the telescopic air pipe, the air storage box, the air outlet, the air outlet, the first motor, the lead screw and the ear. The connecting pipe is inserted into the plugging cover through the connecting hole, the connecting pipe is inserted into the inside of the embedding ring, the embedding block is inserted into the embedding groove, the connecting pipe is rotated, and the ears on both sides of the plugging cover slide out of the connecting groove. Due to the buoyancy of the liquid, the mounting seat is separated, so that the liquid storage box and the connecting pipe are connected. The liquid storage box is placed on the upper part of the liquid supply box. When the liquid level of the liquid supply box is low, the floating sheet slides down along the first sliding rod to separate the block from the connecting pipe. The water in the liquid storage box enters the liquid supply box through the connecting pipe to replenish the liquid in the liquid supply box. The liquid supply device outside the cleaning machine can be automatically replenished with water, and the liquid can be quickly replenished by replacing the liquid storage box, so as to prevent work from stopping when replenishing the liquid, thereby improving the working efficiency of the cleaning work.

Due to the buoyancy of the liquid, it is separated from the mounting seat 16, so that the liquid storage tank 14 is connected with the connecting pipe 2, and the liquid storage tank 14 is placed on the upper part of the liquid supply tank 1. When the liquid level of the liquid supply tank 1 is low, the floating plate 7 slides down along the first sliding rod 5, so that the blocking block 8 is separated from the connecting pipe 2, and the water in the liquid storage tank 14 enters the liquid supply tank 1 through the connecting pipe 2 to replenish the liquid in the liquid supply tank 1. The connecting pipe 2 is driven up and down by adjusting the thread 3, so as to control the height of the floating plate 7 and the liquid level height when the liquid supply tank 1 is filled with liquid.
