As shown in fig. 1 to 2, an embodiment of the present application provides a tissue washing device including a water storage tank 100, a washing tank 200, a driving pump 400, and a flow regulator 500. The washing tank 200 is connected to the water storage tank 100, and has a drain pipe thereon. The carrier web 300 is detachably installed in the wash tank 200. The driving pump 400 is installed between the water storage tank 100 and the washing tank 200, and is capable of pumping water in the water storage tank 100 into the washing tank 200. The flow regulator 500 is installed to a drain pipe and can regulate a drainage flow of the drain pipe.

In the present embodiment, the pumping flow rate and the drainage flow rate of the driving pump 400 are equal.

Specifically, in using the device, tissue is first placed on the surface of the carrier web 300, and then the carrier web 300 is installed into the wash tank 200. The driving pump 400 is activated, and the driving pump 400 pumps the water in the water storage tank 100 to the inner wall of the washing tank 200 until the distance between the tissue and the bottom of the washing tank 200 is approximately equal to the distance between the tissue and the water level. The flow regulator 500 is then activated and the drain flow is controlled by the flow regulator 500 such that the pump flow is equal to the drain flow and the wash is continued for 12-24 hours.

The tissue washing device provided by the application adopts the driving pump 400 and the flow regulator 500, so that the pumping flow and the drainage flow are consistent, and further the tissue can be washed by using running water, and the washing effect is good. And, through the cooperation with water storage tank 100, in the washing process, need not the experimenter trade water or moisturizing, the washing is convenient, helps improving the convenience of using. In addition, since the pump 400 is driven to pump water to the inner wall of the washing tank 200, the water flow can be prevented from flowing to the tissue, the impact force of the water flow on the tissue can be effectively reduced, and the tissue can be effectively protected, compared with the related art in which the water tap is used for washing. Since the distance between the tissue and the bottom of the wash tank 200 is approximately equal to the distance between the tissue and the water level, the impact of the water flow on the tissue can be reduced as well.

Optionally, the carrying net 300 is configured as a metal net, and the mesh size of the metal net is adjustable.

By the arrangement, the corresponding carrying net 300 can be selected according to the size of the organization, which is beneficial to improving the application range of the device.

In one embodiment of the present application, referring to fig. 1 to 2 together, the tissue washing device further includes a liquid level sensor 600 and a controller, wherein the liquid level sensor 600 is mounted on the cover 220 and is used for detecting the liquid level of the water in the tank 210, and the controller is electrically connected to the driving pump 400, the flow regulator 500 and the liquid level sensor 600 and is configured to control the driving pump 400 and the flow regulator 500 according to the signal of the liquid level sensor 600. The controller is configured to turn on the drive pump 400 when the liquid level reaches a first preset threshold and is further configured to turn off the drive pump 400 when the liquid level reaches a second preset threshold. The controller is configured to control the flow regulator 500 to reduce the drain flow when the liquid level reaches a first preset threshold, and is further configured to increase the drain flow when the liquid level reaches a second preset threshold.

In this embodiment, the liquid level of the first preset threshold is lower than the liquid level of the second preset threshold.

Specifically, in the actual application process, when the consistency of the pumping flow rate and the drainage flow rate cannot be ensured, there are the following two cases. One is that the pumping flow is greater than the draining flow, which may cause the water level in the wash tank 200 to gradually rise and even overflow. The other is that the pumping flow is less than the draining flow, which results in a gradual drop in the water level in the wash tank 200 until the water cannot submerge the tissue.

More specifically, when the pumping flow is greater than the drain flow, the water level gradually rises until the water level rises to a second preset threshold. At this time, the controller controls the driving pump 400 to be turned off, and the driving pump 400 stops pumping water into the wash tank 200; at the same time, the controller controls the flow regulator 500 to increase the drainage flow, so that the drainage of the wash tank 200 can be accelerated. This enables the water level to gradually drop. When the pumping flow is smaller than the draining flow, the water level gradually decreases until the water level decreases to a first preset threshold. At this time, the controller controls the driving pump 400 to be turned on, and the driving pump 400 pumps water into the wash tank 200; and the controller controls the flow regulator 500 to reduce the drainage flow, so that the drainage of the wash tank 200 can be slowed down. This enables the water level to rise gradually.

So set up, adopt level sensor 600 and controller, can be according to actual water level condition, control drive pump 400 and flow regulator 500 automatically regulated wash tank 200 internal water level can be made the water level be in reasonable within range all the time. In summary, the occurrence of the condition that the water level is too low or too high can be prevented, the washing effect can be ensured, and the convenience of use can be further improved.
