Description

Technical Field

[0001] This utility model relates to the field of filling technology, and in particular to a double-headed anti-drip liquid culture medium dispensing head. Background Technology

[0002] With the development of plant tissue culture research and industry, many research institutions and tissue culture factories need to prepare plant culture media. When a crop line is produced on a large scale, the preparation volume of a single culture medium is enormous, and large-scale dispensing machines are often used to dispense media into ten or more culture containers at a time. However, different plant species, strains, stages, and seasons require different culture media, necessitating extensive research and adjustments. In such cases, many types of culture media are prepared, but the quantity of each type is small, thus requiring smaller plant culture medium dispensing machines. Existing small plant culture medium dispensing machines all use single-head dispensing, dispensing one culture container at a time. This results in low dispensing efficiency, and if the dispensing time is long, the culture medium will solidify after the temperature drops, making further dispensing difficult.

[0003] Liquid culture medium must be dispensed in a way that prevents dripping. Dripping not only wastes medium but also increases the likelihood of contamination. During inoculation, airborne spores are more likely to land at the rim of the culture container. During cultivation, the chances of airborne spores entering the rim are also highest. Therefore, culture medium dripping onto the rim provides nutrients for contaminating microorganisms, leading to contamination of the culture material. Culture medium dripping onto tabletops or work surfaces also increases the amount of cleaning required. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of small plant culture medium dispensing machines that all use single-head dispensing, dispensing one culture container at a time, resulting in low dispensing efficiency and the culture medium condensing after the temperature drops due to long dispensing time, making it difficult to dispense further. Therefore, a double-headed anti-drip liquid culture medium dispensing head is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A double-headed anti-drip liquid culture medium dispensing head includes an inlet pipe, a handle sleeve, a connecting horizontal pipe, two valves, two anti-drip arches, and two outlet pipes. The inlet pipe is fixedly connected to the connecting horizontal pipe, and both ends of the connecting horizontal pipe are fixedly connected to one end of each of the two anti-drip arches. The two valves are respectively installed on the two connecting horizontal pipes. The handle sleeve is located on the outside of the inlet pipe. One end of each of the two outlet pipes is fixedly connected to the other end of each of the two anti-drip arches. The other ends of the two outlet pipes are respectively provided with a first culture medium outlet and a second culture medium outlet.

[0007] Preferably, a plurality of thin steel strips are fixedly installed inside the grip sleeve, and one end of each of the thin steel strips is fixedly connected to the outside of the liquid inlet pipe.

[0008] Preferably, the inlet pipe is located between the two valves.

[0009] Preferably, the length of the grip sleeve is 11cm.

[0010] Preferably, the distance between the first culture medium outlet and the second culture medium outlet is 8 cm.

[0011] The handle sleeve is fixed to the inlet pipe at both ends by thin steel strips, which can prevent the heat of the culture medium from being transferred to the sleeve, thus preventing the handle sleeve from getting hot to the touch. Since the temperature of plant culture medium is usually between 70 and 90°C when it is freshly prepared, the inlet and outlet pipes are prone to getting hot to the touch during long-term dispensing.

[0012] The culture medium outlet tube has an arched bend, called an anti-drip arch, with the lower inner wall of the highest point of the arch being 0.3cm to 0.5cm higher than the upper inner wall of the connecting horizontal tube. When the dispensing head is moved horizontally during culture medium dispensing, the arched bend prevents the inertia of the culture medium inside the connecting horizontal tube from flowing out of the outlet tube in the opposite direction of the movement, forming a drip that falls into the mouth of the dispensing container or outside the container.

[0013] The distance between the two outlet pipes is similar to the diameter of the plant culture container. In other words, the total horizontal span of the connecting horizontal pipe, the two anti-drip arch pipes, and the two outlet pipes is close to the diameter of the dispensing container, allowing the culture medium to be injected from the center of the container opening. Common plant culture containers typically have diameters between 7cm and 14cm, and 3-4 different lengths of the connecting horizontal pipes can be provided to meet the culture medium dispensing requirements of all conventional culture containers.

[0014] The size, length, and height difference of the connecting horizontal tube, the anti-drip arch tube, and the outlet tube are all symmetrical and consistent. The connecting horizontal tube is perpendicular to the inlet tube, which ensures that the amount and flow rate of the culture medium flowing to the two outlet tubes are consistent, and the amount of culture medium dispensed into the two containers is also consistent.

[0015] The outlet tube must be vertical to prevent the culture medium from being sprayed sideways. The opening of the outlet tube should be 1-2 cm lower than the connecting horizontal tube, and the opening of the outlet tube should be able to fit into the opening of the culture container to facilitate the injection of the culture medium into the container.

[0016] Compared with the prior art, the advantages of this utility model are:

[0017] This invention can simultaneously dispense culture medium into two culture containers, improving dispensing efficiency, shortening dispensing time, and effectively preventing the culture medium from condensing when cooled. Attached Figure Description

[0020] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this embodiment, and not all embodiments.

[0021] Reference Figure 1 A double-headed anti-drip liquid culture medium dispensing head includes an inlet pipe 1, a handle sleeve 3, a connecting horizontal pipe 2, two valves 7, two anti-drip arches 5, and two outlet pipes 6. The inlet pipe 1 is fixedly connected to the connecting horizontal pipe 2, and both ends of the connecting horizontal pipe 2 are fixedly connected to one end of the two anti-drip arches 5, respectively. The two valves 7 are respectively installed on the two connecting horizontal pipes 2. The handle sleeve 3 is located on the outside of the inlet pipe 1. One end of the two outlet pipes 6 is fixedly connected to the other end of the two anti-drip arches 5, respectively. The other end of the two outlet pipes 6 is respectively provided with a first culture medium outlet 8 and a second culture medium outlet 9.

[0022] In this embodiment, a plurality of thin steel bars 4 are fixedly installed inside the grip sleeve 3, and one end of each of the plurality of thin steel bars 4 is fixedly connected to the outside of the liquid inlet pipe 1.

[0023] In this embodiment, the inlet pipe 1 is located between two valves 7. Opening one valve 7 allows for filling of a single container, while opening both valves 7 allows for filling of two containers simultaneously.

[0024] In this embodiment, the grip sleeve 3 has a diameter of 2.5 cm, and the outer diameter of the liquid inlet pipe 1 is 1.0 cm, while the inner diameter is 0.7 cm. Both ends of the grip sleeve 3 are welded and fixed to the liquid inlet pipe 1 with multiple thin steel strips 4 to reduce the heat transfer from the culture to the grip sleeve 3, which would cause it to become too hot to handle.

[0025] The lower inner wall of the highest point of the anti-drip arch 5 is slightly higher than the upper inner wall of the connecting horizontal pipe 2, thus preventing culture medium leakage during the translation of the dispensing head.

[0026] The distance between the first culture medium outlet 8 and the second culture medium outlet 9 is similar to the diameter of the plant culture container, allowing the culture medium to be injected from the middle of the container opening.

[0027] The size, length, and arch height of the connecting horizontal pipe 2, the anti-drip arch pipe 5, and the outlet pipe 6 are all symmetrical and consistent. The connecting horizontal pipe 2 is perpendicularly connected to the inlet pipe 1, ensuring that the flow rate and volume of the culture medium flowing to the two outlet pipes are consistent, meaning that the amount of culture medium dispensed into the two culture containers is the same. The outlet pipe 6 is vertical, preventing the culture medium from being sprayed sideways, and the first culture medium outlet 8 and the second culture medium outlet 9 are lower than the connecting horizontal pipe 2, facilitating the injection of culture medium into the containers.

[0028] One end of the inlet of the inlet pipe 1 is connected to a small culture medium dispenser via a rubber tube. The freshly prepared plant culture medium is in liquid form and is pumped into the inlet pipe 1 by the dispenser. It flows to the connection point of the horizontal connecting pipe 2, where it is split into two horizontal connecting pipes 2 on both sides. Then, it passes through the anti-drip arch pipe 5 and exits through the outlet pipe 6 into the dispensing container. From the end of the inlet pipe, the size of the lumen, the length of the pipe, and the height difference of the arch pipe are all symmetrical and consistent. Therefore, the flow rate and volume of the culture medium are consistent on both sides, and the amount of culture medium dispensed into the two containers is also consistent. It is only necessary to adjust the single dispensing volume of the dispenser to twice the required amount of the container.

[0029] Because the temperature of freshly prepared plant culture medium is generally between 70 and 90°C, the pipes and dispensing head can easily become hot and scalding to the touch after being dispensed for a period of time. The handle sleeve serves as a handle for the dispensing head, and its diameter should be convenient for gripping, and its position should also be convenient for shaking hands. The diameter should be 2 to 4 cm, about 1 to 3 cm larger than the inlet pipe, and the length should be about 10 cm.

[0030] Before the culture medium outlet tube, there is an arched bend, called the anti-drip arch. The lower inner wall of the highest point of the arch is 0.3cm to 0.5cm higher than the upper inner wall of the connecting horizontal tube. The function of the arch is to prevent the culture medium from flowing out of the outlet tube in the opposite direction of translation when the dispensing head is moved, thus preventing the culture medium from dripping and falling into the mouth of the dispensing container or outside the container.

[0031] The distance between the two outlet pipes 6 is similar to the diameter of the plant culture container. This means the total horizontal span of the connecting horizontal pipe, the two anti-drip arch pipes, and the two outlet pipes is close to the diameter of the dispensing container, allowing the dispensed culture medium to be injected from the center of the container opening. Since the diameter of commonly used plant culture containers ranges from 7cm to 14cm, 3 to 4 different lengths of the connecting horizontal pipes can be provided to meet the culture medium dispensing requirements of all conventional culture containers.

[0032] The outlet pipe 6 should be vertical to prevent the culture medium from being sprayed sideways. Its culture medium outlet should be 1.0 to 2.0 cm lower than the connecting horizontal pipe so that the outlet can extend into the container opening, which is conducive to the injection of culture medium into the container and also prevents the culture medium from splashing to the container opening or outside the container.

[0033] The above description is only a preferred embodiment of this practice, but the scope of protection of this embodiment is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in this embodiment, based on the technical solution and the inventive concept of this embodiment, should be covered within the scope of protection of this embodiment.
