Description

Technical Field

[0001] This utility model belongs to the technical field of fungal inoculation tools, and particularly relates to a fungal slant inoculation tool. Background Technology

[0002] In the process of microbial culture, various inoculation tools such as inoculation loops, inoculation needles, and inoculation shovels are often used depending on the type of microorganism. Especially in large-scale industrial production, the propagation of fungal bran koji strains often requires scraping spores from slant culture media and inoculating them into bran koji culture media.

[0003] Traditional inoculation tools are mostly inoculation rings, inoculation shovels, etc. An inoculation ring is an inoculation needle with a round or triangular head, smooth or with various structures such as wire loops or serrated strips, used to encircle or hook the fungal spores and then inoculate them into the culture medium. An inoculation shovel is usually a shovel-shaped inoculation tool with a convex or flat front end that is fully open, used to scoop up slant spores and then inoculate them into solid or liquid culture media.

[0004] All of these inoculation tools suffer from problems such as incomplete spore collection and easy spore spillage. Inoculation heads with complex structures also have drawbacks such as incomplete sterilization and long burning sterilization time, which pose a risk of inoculation contamination, resulting in waste of spores, low inoculation efficiency, and affecting the quality of spore propagation. Utility Model Content

[0005] The purpose of this invention is to provide a fungal slant inoculation tool that effectively solves the problems of incomplete spore collection and easy spore spillage when scraping spores with existing inoculation tools.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A fungal slant inoculation tool includes a handle, a connecting rod, and a scraper. The front end of the handle is fixedly connected to the rear end of the connecting rod, and the front end of the connecting rod is connected to the middle position of the rear end of the scraper.

[0008] The scraping shovel includes a shovel surface and baffles. The baffles are arranged around the shovel surface. The front end of the shovel surface is concave and crescent-shaped. There is a gap between the baffles located on the front side of the shovel surface and the front edge of the shovel surface. The vertical distance between the lower edge of the baffles located on the front side of the shovel surface and the crescent-shaped shovel surface is 1-2 mm. The upper edges of each baffle are flush.

[0009] Furthermore, both the handle and the connecting rod are cylindrical, the front end of the handle has a blind hole extending along the handle axis, and the rear end of the connecting rod is inserted into the blind hole.

[0010] Furthermore, the curvature of the crescent-shaped shovel surface is 120° to 140°.

[0011] Furthermore, the scraping spatula is made of stainless steel, the connecting rod is made of stainless steel, and the handle is made of silicone.

[0012] Furthermore, the baffles located on the rear, left, and right sides of the shovel face are all integrated with the shovel face, and the left and right ends of the baffle located on the front of the shovel face are connected to the baffles located on the left and right sides of the shovel face, respectively.

[0013] Compared with the prior art, the beneficial technical effects of this utility model are:

[0014] (1) This utility model, through the cooperation between the crescent-shaped shovel surface and the baffle located on the front side of the shovel, is conducive to quickly scraping and collecting slant spores, avoiding the overflow and spillage of spores, reducing contamination by miscellaneous bacteria and waste of strains, and improving the efficiency of strain propagation.

[0015] (2) This utility model uses a handle made of high temperature resistant, heat-proof and non-slip silicone, which is not only easy to grip, but also provides effective heat insulation when sterilizing with an alcohol lamp, making it less likely to be burned and improving the safety of operation.

[0016] (3) This utility model integrates the scraping spatula and the connecting rod into one piece. Both the scraping spatula and the connecting rod are made of stainless steel. The structure is simple, not easy to bend or break, and suitable for repeated use. It can quickly and thoroughly sterilize during inoculation, improve inoculation efficiency, and reduce the risk of contamination. Attached Figure Description

[0023] Example 1: As Figure 1As shown, a fungal slant inoculation tool includes a handle 1, a connecting rod 2, and a scraper 3. The front end of the handle 1 is fixedly connected to the rear end of the connecting rod 2, and the front end of the connecting rod 2 is tightly connected to the middle of the rear end of the scraper 3. In this embodiment, the handle 1 is made of high-temperature resistant, heat-resistant silicone material, while the connecting rod 2 and the scraper 3 are both made of stainless steel. Both the handle 1 and the connecting rod 2 are cylindrical. The front end of the handle 1 has a blind hole extending axially along the handle 1, and the rear end of the connecting rod 2 is inserted into the blind hole. Figure 2 and Figure 3 As shown.

[0024] The scraping shovel 3 includes a shovel surface 4 and baffles 5. The baffles 5 are located around the shovel surface 4. The baffles 5 located on the rear, left and right sides of the shovel surface 4 are all tightly connected to the shovel surface 4 as one unit. The left and right ends of the baffle 7 located on the front side of the shovel surface 4 are connected to the baffles 5 located on the left and right sides of the shovel surface 4, respectively.

[0025] like Figure 2 and Figure 5 As shown, the front end of the shovel surface 4 is concave and crescent-shaped. A gap exists between the baffle 7 located on the front side of the shovel surface 4 and the front edge of the shovel surface 4. This gap allows the crescent-shaped shovel surface 6 to effectively contain and block the spores as they scrape forward, causing them to quickly accumulate inside the shovel and preventing spillage. This helps reduce contamination by other microorganisms and waste of inoculum, thus improving inoculation efficiency.

[0026] In this embodiment, the curvature of the crescent-shaped shovel surface 6 is 120° to 140°. For example... Figure 4 As shown, the lower edge of the baffle 7 located on the front side of the shovel face is 1-2 mm away from the crescent-shaped shovel face 6, and the upper edges of each baffle 5 are flush.

[0027] In this embodiment, the diameter of the handle 1 is 6-8 mm and the total length is 8-10 cm; the diameter of the blind hole on the handle 1 is 2-3 mm and the length is 5-7 cm. The length of the connecting rod 2 is 20-22 cm. The length of the scraping spatula 3 is 8-10 mm and the width is 5-6 mm.

[0028] The method of using this utility model is as follows: When it is necessary to scrape slant spores, first wipe the utility model with alcohol for disinfection, and then sterilize it by burning with an alcohol lamp. Insert the scraping spatula 3 into the eggplant bottle and place it horizontally on the slant culture medium. Gently push the crescent-shaped spatula 6 forward to scrape the spores. At the same time, the baffle 7 located on the front side of the spatula can effectively and timely encircle and block the spores, causing them to quickly accumulate in the spatula. After the spores are scraped, the spores are then inoculated into the culture medium to be expanded.

[0029] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
