Description

TECHNICAL FIELD

[0001] The utility model relates to water sample detection field, concretely for a device for collecting microorganism in water sample. BACKGROUND

[0002] Chinese utility model patent 2019219057758 discloses a device for sampling and interpreting microorganism for experiment personnel, and in the background art, it is recorded that "in the microorganism detection process of water sample, the usual operation method is: first, use cotton swab to inoculate the collected microorganism into liquid culture medium to culture. Then judge the species of microorganism or whether it is overproof through the metabolic product of the detection microorganism in the culture process. For example, when the experiment personnel detects colibacillus in drinking water, usually, the culture medium inoculated with water sample is placed in the incubator under the condition of about 37 DEG C and cultured for 24h. When producing acid, the solution will change from purple to yellow. When producing gas, there will be air bubbles in the inverted fermentation tube. If no gas is generated in all the added fermentation tubes, report the gas-producing microorganism as negative, if there is a gas-producing tube, separation culture is needed, that is, corresponding culture medium identification experiment is carried out.

[0003] However, in the actual experiment process, after the small catheter is placed into the liquid culture medium, the opening end of the small catheter may change position due to the transfer of the culture medium or the buoyancy of the culture medium and other self factors, and the non-experiment personnel throws the small catheter, which misjudges the opening direction.

[0004] To this end, in order not to affect the experiment process, it is necessary for the experiment personnel to design a new device for collecting culture microorganism sample. SUMMARY

[0005] The utility model provides a device for collecting microorganism in water sample, and the device avoids the displacement of the opening end of the fermentation small tube and affects the collection of microorganism metabolic gas through the design of the channel for fixing the fermentation small tube.

[0006] To achieve the above purpose, the utility model provides the following technical scheme:

[0007] A device for collecting microorganism in water sample, including conical flask, joint cover and sealing cover,

[0008] The joint cover includes a threaded ring, a buckle part and an arc-shaped connecting part, the inner side end of the arc-shaped connecting part is fixedly provided with a guide channel suitable for the passage of the fermentation small tube, the threaded ring is fixed to the upper end of the arc-shaped connecting part, and the sealing cover and the threaded ring are screw-fixed.

[0009] The advantage of throwing the fermentation tube into the guide channel is that the opening end of the fermentation tube can be prevented from being turned upside down or falling down and being resisted by the culture medium during the throwing process.

[0010] Preferably, a breathable barrier cloth is clamped between the sealing cover and the threaded ring.

[0011] The breathable barrier cloth can prevent foreign matters from entering the culture medium and achieve the function of air permeability.

[0012] Preferably, an arc-shaped air permeable through hole is arranged above the sealing cover.

[0013] Preferably, an arc-shaped sliding rail is arranged on the inner side of the sealing cover, an arc-shaped sliding groove is arranged on the arc-shaped sliding rail, an arc-shaped sliding block is arranged in the arc-shaped sliding groove, and the arc-shaped sliding block is located below the arc-shaped air permeable through hole.

[0014] The experimenter can select to open or close the arc-shaped sliding block according to the preference of the microorganism, so as to switch between the anaerobic environment and the aerobic environment.

[0015] Preferably, a toggle lever is arranged at the upper end of the arc-shaped sliding block.

[0016] Preferably, a gap is arranged between the guide channel and the bottom end of the conical bottle, and the length of the gap is less than the length of the fermentation tube.

[0017] The device has the following beneficial effects:

[0018] 1. The joint sleeve and the conical bottle are detachably designed, so that the experimenter can replace them according to actual needs. The existing design of the conical bottle does not need to be improved, and the application is more convenient.

[0019] 2. When the experimenter throws the fermentation tube, the opening end of the fermentation tube can be placed upward into the liquid culture medium through the guide channel, so that the fermentation tube is prevented from being turned upside down when it is blocked by the liquid surface, and the opening end of the fermentation tube is prevented from being turned upside down.

[0024] This embodiment provides a technical solution:

[0025] like Figures 1-3 As shown, an apparatus for collecting microorganisms from water samples includes a conical flask 10, a connector sleeve, and a sealing cap 3. The connector sleeve includes a threaded ring 5, a fastening part 7, and an arc-shaped connecting part 6. The inner end of the arc-shaped connecting part 6 is fixed with a guide channel 8 adapted for the passage of fermentation tubes 9. The threaded ring 5 is fixed to the upper end of the arc-shaped connecting part 6, and the sealing cap 3 and the threaded ring 5 are screwed together. A gap is left between the guide channel 8 and the bottom end of the conical flask 10, and the length of the gap is shorter than the length of the fermentation tubes 9.

[0026] The connection relationship and working principle of the conical bottle 10, the connector sleeve, and the sealing cap 3 are as follows:

[0027] The conical flask 10 uses an existing design. During use, a connector of the corresponding size can be fastened to the open end of the conical flask 10. Simultaneously, the fermentation tube 9 is dropped along the guide channel 8, ensuring that the open end of the fermentation tube 9 faces downwards. After the fermentation tube 9 enters the culture medium, because its upper end remains in the guide channel 8 when it touches the bottom, the opening direction of the fermentation tube 9 will not reverse as the culture medium moves.

[0028] like Figure 1 As shown, a breathable shielding cloth 4 is sandwiched between the sealing cap 3 and the threaded ring 5.

[0029] The breathable shielding cloth 4 serves to prevent foreign objects from falling into the conical flask, while also providing ventilation.

[0030] like Figure 2 and Figure 3 As shown, the sealing cover 3 has an arc-shaped vent hole on its upper side. The inner side of the sealing cover 3 has an arc-shaped slide rail with an arc-shaped groove. The arc-shaped groove is fitted with an arc-shaped slider 2, which is located below the arc-shaped vent hole.

[0031] Researchers can choose to isolate the microorganisms for culture based on their preferences. Alternatively, for some beneficial microorganisms, air isolation can be discontinued (the breathable shielding cloth 4 does not prevent air from entering the culture medium, which is a common experimental procedure), and the above process can be achieved by moving the curved slider 2.

[0032] In this embodiment, the upper end of the arc-shaped slider 2 is provided with a toggle lever 1.

[0033] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
