[0001] This utility model relates to the field of drip pump technology, and in particular to a drip pump that can discharge air droplets. Background Technology

[0002] In laboratories and industrial production, drip pumps are widely used to precisely control the delivery rate of liquids.

[0003] A search revealed a Chinese patent disclosure for an acetylacetone dripping pump (authorization announcement number CN209724640U), comprising a drive device for providing torque to the pump body; a delivery pump disposed at the front end of the drive device; and a dripping sleeve mounted on the top of the delivery pump. The dripping sleeve contains a spiral pipe and a sponge pad inside. The diameter of the spiral pipe gradually decreases from the top to the bottom of the dripping sleeve, and a sponge pad is provided at the bottom end of the spiral pipe. This invention features a dripping sleeve mounted at the bottom, with a spiral pipe and a sponge pad inside. The diameter of the spiral pipe gradually decreases from the top to the bottom of the dripping sleeve, and a sponge pad is provided at the bottom end of the spiral pipe. This patented technology increases the flow length of the water through the spiral pipe, reducing the impact force of the water flow. The water flows into the sponge pad, is absorbed and collected by the sponge pad, and forms water droplets at the bottom of the sponge pad before dripping down, achieving the dripping effect.

[0004] However, the above-mentioned devices still have some drawbacks in actual use. The most obvious one is that the traditional drip pump is prone to generating bubbles during the delivery process. The presence of bubbles not only affects the accuracy of liquid measurement, but may also lead to instability in chemical reactions or deviations in experimental data. Utility Model Content

[0005] In view of the above-mentioned problems existing in the prior art, the main objective of this utility model is to provide a drip pump that can discharge air droplets.

[0006] The technical solution of this utility model is as follows: a drip pump capable of discharging aerosols includes a pump body, a worm gear blade rotatably connected inside the pump body, a bubble-piercing assembly provided at the bottom end of the worm gear blade, the bubble-piercing assembly including a bubble-piercing needle and a rotating shaft, the rotating shaft fixedly connected at the bottom end of the worm gear blade, a plurality of bubble-piercing needles fixedly connected at equal intervals on the outer side of the rotating shaft, a connecting flange fixedly connected at the top end of the pump body, a controller fixedly installed at the rear side of the pump body, an infrared bubble sensor fixedly installed at the bottom of the connecting flange, and a foam-absorbing assembly provided on the outer side of the pump body.

This information is then transmitted to the controller, which in turn activates the foam suction component. This allows the foam on the liquid to be absorbed, thus preventing the presence of bubbles from affecting the accuracy of liquid measurement and the rigor of experimental data.

[0008] In a preferred embodiment, the foam suction assembly includes a suction tank fixedly connected to the top of the outer side of the pump body, a piston plate slidably connected inside the suction tank, a suction pipe fixedly connected to one side of the suction tank, and a discharge pipe fixedly connected to the bottom of the suction tank.

[0017] By adopting the above technical solution and setting up a flow meter, the flow rate of the discharged liquid can be monitored.

[0018] In a preferred embodiment, an inlet is fixedly connected to the top of the outer side of the pump body, the inner wall of the pump body is provided with an inclined surface, and a viewing window is fixedly connected to the outer side of the pump body.

[0019] By adopting the above technical solution and setting a viewing window, staff can check the condition of air bubbles inside the pump.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] 1. In this invention, the presence of bubbles is determined by detecting changes in light intensity caused by bubbles in the liquid. This information is then transmitted to the controller, which activates the foam-absorbing component. This absorbs the foam on the liquid, preventing the presence of bubbles from affecting the accuracy of liquid measurement and the rigor of experimental data.

Detailed Implementation

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] Reference Figure 1-5 A drip pump capable of discharging aerosols includes a pump body 1. A worm gear blade 6 is rotatably connected inside the pump body 1. A bubble-piercing assembly is located at the bottom end of the worm gear blade 6. The bubble-piercing assembly includes bubble-piercing needles 7 and a rotating shaft 5. The rotating shaft 5 is fixedly connected to the bottom end of the worm gear blade 6. Multiple bubble-piercing needles 7 are equidistantly fixedly connected to the outer side of the rotating shaft 5. A connecting flange 4 is fixedly connected to the top end of the pump body 1. A controller is fixedly installed on the rear side of the pump body 1. An infrared bubble sensor 15 is fixedly installed at the bottom of the connecting flange 4. A foam-absorbing assembly is located on the outer side of the pump body 1. Through the action of the infrared bubble sensor 15, it can... Based on the photoelectric effect of optoelectronic devices, the presence of bubbles is determined by detecting changes in light intensity caused by bubbles in the liquid. This information is then transmitted to the controller, which activates the foam suction component to absorb the foam on the liquid. This prevents the presence of bubbles from affecting the accuracy of liquid measurement and the rigor of experimental data. Furthermore, the rotation of the worm gear blades 6 drives the rotation of the rotating shaft 5, which in turn drives the rotation of multiple bubble-piercing needles 7. These needles pierce the bubbles in the liquid, reducing the generation of bubbles during transport.

[0031] Specifically, the suction assembly includes a suction tank 11 fixedly connected to the top outer side of the pump body 1. A piston plate 12 is slidably connected inside the suction tank 11. When the piston plate 12 moves to the right, the right side of the piston plate 12 is in a low-pressure state, which allows the suction pipe 17 to absorb the air droplets into the suction tank 11. Then, by pushing the piston plate 12, the air droplets can be pushed to the outside through the discharge pipe 13. The suction pipe 17 is fixedly connected to one side of the suction tank 11, and the discharge pipe 13 is fixedly connected to the bottom end of the suction tank 11. A one-way valve b16 is fixedly installed inside the suction pipe 17. A one-way valve a14 is fixedly installed inside the discharge pipe 13. The one-way valve b16 and the one-way valve a14 can prevent backflow of liquid and ensure the normal operation of the suction assembly. The end of the suction pipe 17 away from the suction tank 11 extends into the pump body 1. A miniature electric telescopic rod 10 is fixedly installed on the side of the suction tank 11 away from the suction pipe 17. The piston rod of the miniature electric telescopic rod 10 extends into the suction tank 11 and is fixedly connected to the piston plate 12. The movement of the piston rod of the miniature electric telescopic rod 10 can drive the piston plate 12 to move laterally.

[0032] Specifically, a servo motor 3 is fixedly installed on the top of the connecting flange 4. The output shaft of the servo motor 3 extends into the interior of the pump body 1 and is fixedly connected to the worm gear blade 6. The servo motor 3 provides rotational power to the worm gear blade 6. A discharge pipe 8 is fixedly connected to the bottom of the pump body 1, and a flow meter 9 is fixedly installed at the bottom of the discharge pipe 8. An inlet is fixedly connected to the top of the outer side of the pump body 1. The inner wall of the pump body 1 is provided with a slope to reduce the impact of liquid entering the pump body 1, thereby reducing the generation of bubbles. A viewing window 2 is fixedly connected to the outer side of the pump body 1 so that the operator can check the bubble status inside the pump body 1.

[0033] Working principle: First, liquid enters pump body 1 through the inlet. The inclined surface reduces the impact of the liquid entering pump body 1, thereby reducing the generation of air bubbles. Infrared bubble sensor 15, based on the photoelectric effect of photoelectric devices, detects the presence of air bubbles by detecting changes in light intensity caused by bubbles in the liquid. This information is then transmitted to the controller, which activates the aeration assembly to absorb the air bubbles on the liquid. This prevents air bubbles from affecting the accuracy of liquid measurement and the rigor of experimental data. Furthermore, the worm gear... The rotation of blade 6 drives the rotation of shaft 5, which in turn drives multiple bubble-piercing needles 7 to rotate. This allows the bubble-piercing needles 7 to pierce and treat the air bubbles in the liquid, reducing the generation of air bubbles during the conveying process. The movement of the piston rod of the micro electric telescopic rod 10 drives the piston plate 12 to move laterally. When the piston plate 12 moves to the right, the right side of the piston plate 12 is in a low-pressure state, which allows the air droplets to be absorbed into the suction tank 11 through the suction pipe 17. Then, through the pushing of the piston plate 12, the air droplets can be pushed to the outside through the discharge pipe 13.
