Technical Field

[0001] The invention belongs to the technical field of microbial culture and inoculation equipment, and in particular relates to a combined inoculation head containing a detachable alloy inoculation ring. Background Art

[0002] The inoculation loop is a basic tool required in the microbial culture process. It is used to transfer various types of microorganisms to be cultured into the culture medium, or to grab the medium. Its basic structure includes an operating part and an inoculation loop part. Traditional inoculation loops are usually integrated. To meet the needs of automated inoculation equipment, CN202122509758.6 provides a magnetic streaking head structure. It adopts a movable structure and uses a bottom ring inoculation structure to achieve inoculation and streaking. However, its overall cost is relatively high, and the operating direction of the inoculation loop at the bottom of the integrated structure is fixed, which is not conducive to more flexible and diverse automatic streaking operations. Summary of the Invention

DETAILED DESCRIPTION

[0023] The present invention is described in detail below with reference to specific embodiments.

[0024] Compared with the existing automated line inoculation head, the present invention provides a combined inoculation head containing a detachable alloy inoculation ring, which adopts a structure of a detachable alloy inoculation ring and a mounting seat. The alloy inoculation ring has a longer service life, the production process is more mature and simple, and it can be quickly assembled and replaced, which improves the efficiency of automated production and assembly. It can effectively reduce material and processing costs in the process of mass production and assembly, while improving its service life and structural stability. The detachable alloy inoculation ring makes the inoculation head more flexible and customizable and free combination capability, and can be used with inoculation rings of different sizes and standards according to production and assembly needs, effectively enhancing the flexibility of automatic marking equipment production.

[0025] like Figure 1 、 Figure 2 As shown, the main structure of a combined inoculation head containing a detachable alloy inoculation ring of the present application includes a connecting tube 1, a mounting seat 2, an alloy inoculation ring 3, a magnetic suction head 4, and a reset spring 5;

[0026] The mounting tube 1 and the magnetic head 4 are used to construct a basic supporting connection structure. The magnetic head can be directly adsorbed on the magnetic head of the automatic marking device for fixation. The reset spring is used to provide reset and control the marking force during the marking process to prevent the marking head from directly pressing against the culture medium.

[0027] like Figure 3 As shown, the mounting tube 1 is arranged vertically, and an annular limiting portion 1a is provided on the inner edge of the lower end thereof;

[0028] The mounting seat 2 is slidably mounted in the mounting tube 1. An annular positioning portion 2a is provided at the upper end of the mounting seat 2. The positioning portion 2a abuts against the limiting portion 1a to keep the upper end of the mounting seat 2 in the mounting tube 1. A connecting portion 2b is provided at the lower end of the mounting seat 2. A mounting hole 2c is provided on one side of the connecting portion 2b. A clamping block structure 2d is provided below the mounting hole 2c.

[0029] The alloy inoculation ring 3 is a C-shaped structure, comprising a horizontal section 3a at the upper end inserted into the mounting hole 2c, a positioning section 3b in the middle section vertically clamped in the clamping block structure 2d, and a ring section 3c at the bottom;

[0030] The magnetic head 4 is embedded in the top opening of the connecting tube 1 , and the return spring 5 is located inside the connecting tube 1 with its two ends respectively pressing against the magnetic head 4 and the mounting base 2 .

[0031] The design of the detachable inoculation loop can be easily assembled and disassembled. The alloy inoculation loop 3 of the metal structure can be removed separately for high-temperature disinfection and other treatments. At the same time, its structure is simple and easy to process, making it suitable for batch production.

[0032] The alloy inoculation ring 3 can be quickly clamped and fixed through the horizontal section 3a and the positioning section 3b to achieve vertical and left and right side limiting, ensuring that the alloy inoculation ring 3 maintains its own position relatively fixed during the automatic marking process.

[0033] At the same time, compared with inoculation rings made of other materials such as plastic, inoculation rings made of alloy materials can make full use of mature and efficient metal processing technology to better control the shape and size of the ring segment, achieving more precise customization and precise processing design. At the same time, the alloy ring body has better viscosity, and the connecting gap at the end of the metal inoculation ring provides an additional adhesion surface, which makes it have better microbial carrying capacity and can release microbial samples more evenly and stably during the streaking process, thereby meeting the needs of more refined streaking processes and improving the basic capabilities of automated streaking culture equipment in terms of structure and performance.

[0034] Based on actual needs, the alloy inoculation ring 3 in the present invention is preferably made of 304 stainless steel, or nickel-cadmium alloy wire, or platinum wire by bending, and is subjected to necessary surface treatment according to its use requirements.

[0035] Usually, alloy wires with a diameter of 0.5 mm, 0.6 mm or other sizes can be used as required.

[0036] In order to meet the necessary control accuracy, the inner diameter of the annular segment 3c needs to be designed and optimized accordingly. It can be designed to have an inner diameter of 2mm or 3mm. In other cases, an annular segment with a maximum inner diameter of 5mm can also be used.

[0037] The clamping block structure is used to prevent the alloy inoculation ring 3 from swinging left and right, ensuring that the positioning section 3b of the alloy inoculation ring remains vertical during the marking process, so as to facilitate the control of the marking process.

[0038] As a simple and efficient design solution, in this embodiment, a cross-shaped slot 2e is provided on the clamping block structure 2d, and the vertical groove of the cross-shaped slot 2e is directly opposite to the mounting hole 2c.

[0039] During actual assembly, after the horizontal section 3a is inserted into the mounting hole 2c, the positioning section 3b can be clamped by the vertical groove to achieve locking and positioning.

[0040] In order to facilitate the marking accuracy of the annular segment 3c and ensure that the microorganisms in the annular segment 3c can be uniformly discharged, the annular segment 3c is at an angle of 0 to 5 degrees to the horizontal direction (i.e. Figure 3 median angle a).

[0041] like Figure 4 As shown, in particular, to facilitate the installation and positioning of the return spring and provide a sufficient elastic deformation range, an annular positioning groove 2f is provided on the upper section of the mounting base 2, into which the lower end of the return spring 5 is inserted. The annular positioning groove 2f can limit and guide the spring, thereby improving the performance of the scribing head.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present invention.
