A microbial liquid coating device, as shown in figures 1 to 4, comprises a coater arranged at the lower end of a liquid-transferring gun 1; the coater comprises a transition cylinder 2 and a coating head 3 arranged at the lower end of the transition cylinder, the coating head is integrally in a hook shape and comprises a vertical connecting section 4 and a horizontal straight section 5, an arc section 6 is arranged between the connecting section and the straight section, and the free end of the straight section is provided with an upward-turned upwarping section 7; the upper end of the connecting section is fixed at the bottom of the transition cylinder; the cross section of the circular arc section is circular, one side of the lower part of the straight section is of a circular arc structure 8, and the other side of the lower part of the straight section is of a right-angle structure 9, namely, one side of the lower part of the cross section of the straight section is of a circular arc structure, and the other side of the cross section of the straight section is of a right-angle structure. Generally, the cross section of the connecting section is circular, and the cross section of the upturned section is circular.
During coating operation, can utilize the circular arc structure one side of straight section according to the tendency to smooth the bacterial suspension, when needing to strike off or scrape thin coating thickness, utilize straight section right angle structure one side to scrape the operation can. In an alternative embodiment, a convex rounded corner structure 10 is formed between the upward-warped section and the straight section, and the upward-warped section is bent towards one side of the connecting section. When being close to the corner or the turning of culture dish, utilize the fillet structure of evagination to coat can, when guaranteeing the coating effect, can the maximize utilize culture dish, effectively improve the utilization ratio of equipment.
When the local repeated coating operation is needed, the arc section part is utilized. It should be noted that, the above-mentioned operation mode is only an example, and a person skilled in the art can operate according to actual needs, and selectively use the corresponding structure of the coating head to perform the coating operation, so that the coating quality and efficiency are improved, and time and labor are saved.
Aiming at the problems that a large number of coating rods are needed and time and labor are wasted and the efficiency is low when a large number of coating rods are used for coating and inoculating, in an optional embodiment, the upper end of the connecting section is fixed on a base plate 11 of a transition cylinder, and a plurality of through holes 12 are formed in the base plate of the transition cylinder; corresponding to each through hole, the connecting section is correspondingly provided with liquid guide rods 13, the liquid guide rods are obliquely arranged, and the upper ends of the liquid guide rods extend into the transition cylinder through the through holes.
