Common in the market metering liquid device comprises plastic emitting screw and syringe needle, and the glue by in the driven by motor pushrod movement passing metering liquid device makes glue flow out from syringe needle.But, there is following problem in existing metering liquid device, when the metering liquid device extrudes required liquid, when weight during 0.3 milligram of left and right sides, this part liquid can be bonded on the syringe needle because the very little meeting of volume is subjected to effect of surface tension, and can not splash into naturally in the container of lower end.Like this, the metering liquid device can not be controlled the outflow of the liquid of low capacity, and this moment, liquid can be bonded on the syringe needle.
The utility model content
Main purpose of the present utility model provides a kind of metering liquid device that can control accurate low capacity liquid outflow.
In order to achieve the above object, the utility model proposes a kind of metering liquid device, comprise syringe needle and plastic emitting screw, also comprise: be sheathed on the plastic emitting screw and innerly be provided with the fluid mouth that cavity is used for being located on described syringe needle; With the connector gas input device that be connected, that be used in described cavity, importing gas that the sidewall of described fluid mouth is offered.
Preferably, the end of described fluid mouth is positioned at the top of described syringe needle.
Preferably, described connector is provided with internal thread, and an end of described gas input device is provided with external screw thread, and an end of described gas input device inserts described connector and connects by threaded engagement.
Preferably, described fluid mouth and described plastic emitting screw are for being threaded.
Preferably, described syringe needle is positioned at the center of described cavity.
Preferably, the exit of described cavity is throat structure wide at the top and narrow at the bottom.
The utility model further also proposes a kind of point gum machine, comprises aforesaid metering liquid device.
The metering liquid device that the utility model proposes by establishing a cavity in the fluid mouth, can feed gas in the cavity when needed, and like this, gas forms an air mass at airtight cavity, and air mass blows downwards a spot of liquid is blown in the container of lower end.Utilize air pressure to blow out the liquid of small size, like this, even the weight of the liquid that the metering liquid device extrudes is very little, liquid can not be bonded to influence on the syringe needle yet and normally go out liquid, thereby make this metering liquid device can control accurate low capacity liquid and flow out simple in structure, easy realization simultaneously.

Fig. 1 is the sectional structure schematic diagram of the utility model metering liquid device preferred embodiment;
Fig. 2 is the structure for amplifying schematic diagram at A shown in Figure 1 place;
Fig. 3 is three-dimensional exploded view shown in Figure 2.
The realization of the utility model purpose, functional characteristics and advantage will be in conjunction with the embodiments, are described further with reference to accompanying drawing.
The specific embodiment
Be described further with regard to the technical solution of the utility model below in conjunction with drawings and the specific embodiments.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Referring to figs. 1 through Fig. 3, Fig. 1 is the sectional structure schematic diagram of the utility model metering liquid device preferred embodiment; Fig. 2 is the structure for amplifying schematic diagram at A shown in Figure 1 place; Fig. 3 is three-dimensional exploded view shown in Figure 2.
The utility model proposes a kind of metering liquid device, the metering liquid device comprises plastic emitting screw 10 and the syringe needle 20 that is connected with plastic emitting screw 10 in the present embodiment, and this metering liquid device also comprises and is sheathed on the plastic emitting screw 10 and innerly is provided with the fluid mouth 30 that cavity 31 is used for being located on syringe needle 20; The connector offered with the sidewall of fluid mouth 30 is 32 that be connected, be used for the gas input devices 40 of input gases in the cavity 31.Particularly, the end of fluid mouth 30 is positioned at the top of syringe needle 20.
During this metering liquid device busy, the glue by in the driven by motor pushrod movement passing metering liquid device makes glue flow out from syringe needle 20.The weight of the liquid that extrudes when the metering liquid device is below 0.3 milligram the time, when this part liquid is subjected to effect of surface tension can be bonded on the end of syringe needle 20, by the cavity 31 input gases in 40 pairs of fluid mouths of gas input device 30, gas forms an air mass at airtight cavity, and air mass blows the container that a spot of liquid is blown into the lower end that is positioned at syringe needle 20 downwards.Utilize air pressure to blow out the liquid of small size, like this, even the weight of the liquid that the metering liquid device extrudes is very little, liquid can not be bonded to influence on the syringe needle 20 yet and normally go out liquid.
The metering liquid device that the utility model proposes by establishing a cavity 31 in the fluid mouth 30, can feed gas in the cavity 31 when needed, and like this, gas forms an air mass at airtight cavity, and air mass blows downwards a spot of liquid is blown in the container of lower end.Utilize air pressure to blow out the liquid of small size, like this, even the weight of the liquid that the metering liquid device extrudes is very little, liquid can not be bonded to influence on the syringe needle 20 yet and normally go out liquid, thereby make this metering liquid device can control accurate low capacity liquid and flow out simple in structure, easy realization simultaneously.
In the present embodiment, connector 32 is provided with internal thread, and an end of gas input device 40 is provided with external screw thread, and an end of gas input device 40 inserts connector 32 and connects by threaded engagement.Like this, the dismounting that makes connector 32 and gas input device 40 with connection procedure is very simple, convenient, the good seal performance of while junction.
Preferably, fluid mouth 30 and plastic emitting screw 10 are for being threaded.Like this, the dismounting that makes fluid mouth 30 and plastic emitting screw 10 is with connection procedure is very simple, make things convenient for.
Further, syringe needle 20 is positioned at the center of cavity 31.Like this, when gas forms an air mass at airtight cavity, air mass blows downwards a spot of liquid is blown in the container of lower end, be positioned at the center of cavity 31 because of syringe needle 20, so air mass is more even to the power of liquid, thereby make the container of the lower end that is positioned at syringe needle 20 that is dropped in appointment that liquid can be stable.
Preferably, the exit of cavity 31 is throat structure wide at the top and narrow at the bottom.Like this, gas forms air mass in cavity 31 after, the throat structure in the exit of cavity 31, like this, even very little air pressure through reducing compile effect after, blow out the liquid of small size.
The utility model further also proposes a kind of point gum machine, and this point gum machine comprises the metering liquid device, and the concrete structure of this metering liquid device does not repeat them here with reference to above-described embodiment.
