Description

Technical Field

[0001] The invention relates to the technical field of water purification, and in particular to a water purification device for an ultrasonic scanning microscope. Background Art

[0002] The purification device is a device that breaks up the excess algae in the water body through ultrasound. When using the water purification device, the water to be purified is pumped into the interior of the connection box by a water pump, the algae are separated according to different sizes by a layered filter, and ultrasonic waves are generated by an ultrasonic generator, and then the algae are broken up by ultrasound. The broken algae pass through the filter and are flushed out of the interior of the connection box, thereby purifying the water body. In this process, when the ultrasonic wave emitted by the ultrasonic generator passes through the algae, the ultrasonic wave can scan the algae, and then the signal is transmitted to the display screen through the connecting line. The algae magnified by the ultrasonic scanning microscope can be viewed through the display screen, and then the content of the algae in the water can be understood, so that the degree of water purification can be understood to a certain extent.

[0003] The inventor has found in his daily work that the purification device still has at least the following problems: when using the water purification device, the water to be purified is pumped into the interior of the connection box by a water pump, the algae are separated according to different sizes by a layered filter, and an ultrasonic generator generates ultrasonic waves, which are then used to break the algae. The broken algae pass through the filter and are flushed out of the interior of the connection box. During this process, when the ultrasonic waves emitted by the ultrasonic generator pass through the algae, the ultrasonic waves can scan the algae, and then the signal is transmitted to the display screen through the connecting line. The algae magnified by the ultrasonic scanning microscope can be viewed on the display screen, and the content of the algae in the water can be understood. In this way, the degree of water purification can be understood to a certain extent. However, in actual use, because most purification devices are set outdoors, the display screen is easily damaged when it is in the outdoor environment for a long time, so people usually carry it with them and install the display screen on the purification device when they need to observe. It is troublesome to observe the degree of water purification in this way. Summary of the invention
