[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model. Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the claimed present utility model, but merely represents selected embodiments of the present utility model.

[0026] In the description of the present utility model, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0027] The following will further elaborate on the present utility model in conjunction with the attached Figure 1 drawings.

[0028] As Figure 1 shown, the present disclosure provides an observation device for a nano-sound spotting instrument, including an observation cylinder 10 and a filter screen 20. The internal space of the observation cylinder 10 is set as a receiving cavity 11 for accommodating micro-droplets. Both ends of the observation cylinder 10 are open ends. The first end of the observation cylinder 10 is used to connect to the outlet of the storage component, so that the micro-droplets in the storage component can flow into the receiving cavity 11. The second end of the observation cylinder 10 is used to communicate with a capillary tube. The filter screen 20 is disposed on the observation cylinder 10 and close to the first end. The filter screen 20 is configured to filter the micro-droplets flowing from the outlet of the storage component into the receiving cavity 11 to remove foam.

[0029] Through the above technical solution, by providing the observation cylinder 10, the storage component is connected to the capillary tube through the observation cylinder 10, so that the micro-droplets in the bearing chamber can enter the receiving cavity 11. And, a filter screen 20 is disposed at a position close to the open end on the observation cylinder 10. In this way, the filter screen 20 can filter the micro-droplets flowing from the outlet of the storage component into the observation cylinder 10. During the filtering process, the foam in the oil liquid is removed, so that the oil liquid in the observation cylinder 10 is in a foam-free state, which is beneficial for the staff to more accurately grasp the dosage of the micro-droplets used for spotting.

[0030] Among them, the material of the observation cylinder 10 can be a transparent plastic tube

[0031] As an implementation manner, as Figure 1As shown in the figure, the filter screen 20 is arranged along the radial direction of the observation cylinder 10. The filter screen 20 is located in the accommodation cavity 11 of the observation cylinder 10, and the filter screen 20 is detachably connected to the inner cavity wall of the accommodation cavity 11. In this way, it is beneficial to disassemble and replace the dirty filter screen 20.

[0032] As an implementation manner of the detachable connection between the filter screen 20 and the inner cavity wall of the accommodation cavity 11, as Figure 1 shown, the observation device further includes a limiting member 30. The filter screen 20 is located in the accommodation cavity 11 of the observation cylinder 10. A stop portion 13 and a limiting groove 12 are formed on the inner cavity wall of the accommodation cavity 11. The limiting groove 12 is closer to the first end than the stop portion 13. The limiting member 30 is installed in the limiting groove 12. The filter screen 20 is arranged between the limiting member 30 and the stop portion 13. Two sides of the filter screen 20 respectively abut against the stop portion 13 and the limiting member 30. In this way, the filter screen 20 can be clamped and fixed through the cooperation of the limiting member 30 and the stop portion 13, and the situation that the filter screen 20 moves in the horizontal direction (i.e., the axial direction of the observation cylinder 10) can be avoided.

[0033] Among them, the limiting member 30 can be configured as a snap ring structure.

[0034] In an implementation manner of the present disclosure, as Figure 1 shown, the observation device further includes a vertical reflector 40. The vertical reflector 40 is located in the accommodation cavity 11 and extends along the axis direction of the observation cylinder 10. The vertical reflector 40 has two opposite mirror surfaces. Both mirror surfaces are configured to increase the brightness inside the accommodation cavity 11, and scale lines are arranged on both mirror surfaces.

[0035] The light reflection effect can be generated through the mirror surfaces on the vertical reflector 40, so that the light is radiated to the inner cavity wall of the accommodation cavity 11 of the observation cylinder 10, thereby increasing the light intensity inside the accommodation cavity 11, and further increasing the brightness, which is convenient for observing the liquid level of the micro-droplets.

[0036] In order to effectively control the output of the micro-droplets, optionally, as Figure 1 shown, the diameter of the first end of the observation cylinder 10 is larger than the diameter of the second end of the observation cylinder 10.

[0037] The above are only the preferred implementation manners of the present utility model and are not used to limit the present utility model. For those skilled in the art, various changes and modifications can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
