DETAILED DESCRIPTION

[0020] The utility model Figures 1 to 4 As shown, a novel multi-channel bottle mouth liquid dispenser includes a bottle mouth liquid suction component 10, a range adjustment component 20 and a liquid dispensing adjustment component 30, wherein:

[0021] The bottle mouth liquid suction component 10 includes a piston seat 11, a piston 12 and a liquid suction tube 13, wherein the piston 12 is movably installed below the piston seat 11, and the liquid suction tube 13 vertically penetrates the piston seat 11 and the piston 12 and extends below the piston 12; the range adjustment component 20 is arranged below the piston 12; the liquid separation adjustment component 30 is arranged beside the piston seat 11, the range adjustment component 20 adjusts the liquid suction volume of the liquid suction tube 13, and the liquid separation adjustment component 30 separates the sucked liquid.

[0022] The bottle-mouth liquid-suctioning assembly 10 further includes a thread conversion joint 14 that matches the piston 12 , and the thread conversion joint 14 and the piston 12 are detachably matched.

[0023] The piston 12 of the bottle mouth suction assembly 10 cooperates with the piston seat 11 to enable the suction tube 13 to suck liquid, and the range adjustment assembly 20 adjusts the amount of liquid sucked by the suction tube 13. The liquid sucked by the suction tube 13 enters the liquid separation adjustment assembly 30, and the liquid separation adjustment assembly 30 separates the sucked liquid.

[0024] Replace the bottle cap of a suitable bottle containing the required liquid with a matching new multi-channel bottle mouth dispenser, and suck the preset range of liquid out of the bottle through the pipette 13 by moving the piston 12 up and down. All parts in contact with the liquid are made of highly corrosion-resistant materials.

[0025] By adopting the bottle mouth liquid suction component 10, the range adjustment component 20 and the liquid dispensing adjustment component 30, the liquid can be sucked, the liquid suction range can be adjusted, and the liquid can be evenly dispensed. The liquid dispensing adjustment component 30 has multiple outlets, and can dispense liquid multiple times at the same time, so as to avoid the liquid outlet being exposed for a long time, and the liquid dispenser can be maintained and cleaned; the liquid can be conveniently and safely adjusted to be evenly dispensed, so as to avoid the liquid outlet being exposed for a long time due to too much liquid being dispensed, and there is a risk of contamination of the liquid in the bottle. The new multi-channel liquid dispenser has a simple structure, is easy to carry and dismantle, and can be conveniently moved.

[0026] The range adjustment assembly 20 includes an adjustment knob, which is slidably mounted on the outer side of the thread conversion joint 14 .

[0027] The range adjustment component 20 also includes a scale rod. The preset range is set by the range adjustment component 20, and the piston 12 is moved to absorb the liquid.

[0028] The liquid dispensing regulating assembly 30 includes a multi-channel liquid dispensing tube 31 , a liquid discharge valve and a liquid discharge tube 32 . The multi-channel liquid dispensing tube 31 is disposed beside the piston seat 11 . The liquid discharge tube 32 is connected to the multi-channel liquid dispensing tube 31 . The liquid discharge valve corresponds to the liquid discharge tube 32 .

[0029] The multi-channel liquid dispensing tube 31 is internally provided with an air cushion 311 for separating the liquid in the liquid dispensing tube 32 from the liquid in the bottle mouth liquid suction assembly 10 and an elastic member 312 for driving the liquid in the liquid dispensing tube 32 to move. The air cushion 311 is connected to the piston 12, and the elastic member 312 is connected to the air cushion 311.

[0030] The liquid separation regulating assembly 30 also includes a safety cap 33 and a connecting line that matches the discharge pipe 32 . One end of the connecting line is connected to the piston seat 11 ; the other end is connected to the safety cap 33 . The safety cap 33 is detachably arranged at the lower end of the discharge pipe 32 .

[0031] After the liquid separation is completed, the safety cap 33 is screwed on in time to prevent residual liquid from dripping and reduce the risk of contact with reagents; the matching safety cap 33 can be removed and replaced, and other suitable reagents can be replaced after cleaning and disinfection. The safety cap 33 has strong air tightness and is not easy to corrode. It can effectively protect the safety of the liquid outlet and reduce the possibility of contamination of the liquid in the bottle.

[0032] The multi-channel dispensing tube 31 includes a corrosion-resistant outer shell and an elastic member 312, which are completely compressed to form an integral structure. The outer shell is adapted to the elastic member 312, has high airtightness, and is easy to disassemble. The multi-channel dispensing tube 31 uses the piston 12 stroke to evenly distribute the liquid transferred from the suction tube 13 to the discharge tube 32. The function of the air cushion 311 is to separate the liquid in the discharge tube 32 from the dispensing tube piston 12. The elastic member 312 moves through the movement of the air cushion 311, thereby driving the movement of the liquid in the discharge tube 32. Since the elastic member 312 is subjected to uniform force, the suction force on the liquid is roughly the same, and the liquid can be separated within a certain precision, thereby achieving a uniform separation effect.

[0033] The multi-channel dispensing tube 31 uses the piston 12 stroke to evenly distribute the liquid transferred from the suction tube 13 to the discharge tube 32. The function of the air cushion 311 in the multi-channel dispensing tube 31 is to separate the liquid in the discharge tube 32 from the dispensing tube piston 12. The air cushion 311 moves through the spring-like motion connected to the dispensing pipe, thereby driving the movement of the liquid in the discharge tube 32.

[0034] In this embodiment, the air cushion 311 can slide up and down. When the liquid aspirating device completes the specified range of liquid aspirating action, the liquid flows into the liquid discharge pipe 32 and enters the liquid separation device for liquid separation.

[0035] The bottle mouth liquid suction component 10, the range adjustment component 20 and the liquid separation adjustment component 30 are all made of corrosion-resistant materials, and the corrosion-resistant material is PTFE, PFA or borosilicate.

[0036] The materials used in the bottle mouth liquid suction component 10, the range adjustment component 20 and the liquid dispensing adjustment component 30 can withstand repeated high-temperature sterilization, withstand most acids, alkalis and organic solvents, and can be used interchangeably with inorganic solvents. They have high air tightness and can be fine-tuned quantitatively. The reflux function of the discharge valve can avoid solution waste.

[0037] The usage and principle of the new multi-channel bottle mouth dispenser are as follows:

[0038] The piston of the bottle mouth suction assembly cooperates with the piston seat to enable the suction tube to absorb liquid, the range adjustment assembly adjusts the amount of liquid absorbed by the suction tube, the liquid absorbed by the suction tube enters the liquid separation adjustment assembly, and the liquid separation adjustment assembly separates the absorbed liquid.

[0039] The design focus of the utility model is that the liquid can be sucked, the liquid sucking range can be adjusted, and the liquid can be evenly dispensed by adopting a bottle mouth liquid suction component, a range adjustment component, and a liquid dispensing adjustment component. The liquid dispensing adjustment component has multiple outlets, and liquid can be dispensed multiple times at the same time, so that the liquid outlet is not exposed for a long time, and the liquid dispenser can be maintained and cleaned; the liquid can be easily and safely adjusted to be evenly dispensed, so that the liquid outlet is not exposed for a long time due to an excessive amount of liquid to be dispensed, and there is a risk of contamination of the liquid in the bottle. The new multi-channel liquid dispenser has a simple structure, is easy to carry and dismantle, and can be conveniently moved.

[0040] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
