Description

Technical Field

[0001] This utility model belongs to the field of conical dripping bucket technology, and particularly relates to conical dripping buckets. Background Technology

[0002] A conical dripper is a conical device used for adding or transferring liquids. It is commonly used in medical and laboratory fields and is usually made of transparent plastic or glass. It has good chemical stability and transparency, making it easy to observe the flow and dripping of the liquid inside. Its conical design helps the liquid to flow to the bottom outlet, reducing residue.

[0003] Common conical drippers are not convenient for controlling the entry and exit of outside air. Air contains impurities, which can contaminate the liquid inside the dripper, leading to waste. Furthermore, conventional conical drippers do not allow for precise control of the amount of liquid added. Therefore, we propose the conical dripper design. Utility Model Content

[0004] The purpose of this invention is to provide a conical dripping bucket to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a conical dripping bucket, comprising:

[0006] A conical dripping bottle, wherein a dripping funnel cover is fixedly installed on the top of the conical dripping bottle, a flow-dividing disc is fixedly installed at the bottom of the dripping funnel cover and inside the conical dripping bottle, an air inlet box is fixedly installed on the flow-dividing disc, an air inlet seat is provided in the air inlet box, an air inlet pipe fixed to the dripping funnel cover is fixedly installed in the air inlet seat, an air inlet hole is opened in the air inlet seat and below the air inlet pipe, and an air filter membrane is fixedly installed in the air inlet seat and at the bottom of the air inlet hole.

[0007] A round rod is slidably installed inside the air inlet pipe. The top end of the round rod passes through the top of the air inlet pipe and the top cover of the dripping funnel and is fixedly installed with an air inlet valve. A blocking block is fixedly installed on the periphery of the round rod inside the air inlet pipe. An annular groove is opened on the top of the top cover of the dripping funnel. A discharge port is opened at the bottom end of the conical dripping bottle. A plastic ball is placed inside the conical dripping bottle and at the top of the discharge port.

[0008] In this technical solution, the air inlet valve provides an air inlet switch for the infusion channel, breaking the vacuum chamber formed by the air inlet valve and the plastic ball, allowing the liquid to flow smoothly into the conical dropper through the infusion pipeline;

[0009] By pressing the air inlet valve, the air inlet valve supports and cooperates with the plastic ball inside the conical drip bottle to achieve a seal inside the cavity, thus preventing gravity infusion from being performed on the upper infusion line.

[0010] Manually press the air inlet valve. The downward movement of the air inlet valve will cause the round rod and the blocking block to move downward until the blocking block is far away from the air inlet of the air inlet pipe. At this time, the outside air will enter the inner cavity of the conical dropper bottle through the annular groove, air inlet valve, air inlet pipe, air inlet hole, air filter membrane, and air inlet box in sequence. At the same time, the air filter membrane can filter the incoming air to prevent impurities in the air from entering the conical dropper bottle. At this time, the sealing system is broken, and the liquid enters the conical dropper bottle by gravity. During the liquid entry process, the liquid in the feed pipe will flow to the top of the distribution disc. The distribution disc can divide the liquid, so that the liquid on the distribution disc can flow evenly from the periphery of the distribution disc into the inner cavity of the conical dropper bottle. This can effectively ensure that the plastic ball is floated smoothly, and at the same time, it can achieve a certain degree of uniform mixing of the liquid. After the infusion is completed, the plastic ball can seal the outlet to prevent the pipeline from dripping dry.

[0011] Furthermore, the above technical solution also includes:

[0012] The discharge pipe is fixedly installed at the bottom of the conical dropper bottle. The conical dropper bottle has graduation lines engraved on one side and a feed pipe is fixedly installed at the top of the conical dropper bottle.

[0013] In this technical solution, the feed pipe is first connected to the upper infusion pipeline, and the discharge pipe is connected to the lower infusion pipeline. The air inlet valve provides an air inlet switch for the infusion channel, breaking the vacuum chamber between the air inlet valve and the plastic ball. The liquid flows smoothly into the conical dropper through the infusion pipeline. During the liquid infusion process, personnel can visually observe the scale line to accurately control the amount of liquid infused.

[0014] In the above technical solution, the discharge pipe is connected to the discharge port, and the feed pipe is connected to the inner cavity of the conical dripping bottle.

[0015] In this technical solution, it is ensured that the liquid in the outlet can flow out through the outlet pipe, and that the liquid can enter the inner cavity of the conical dropper through the inlet pipe.

[0016] In the above technical solution, the air inlet pipe, air inlet seat, air inlet hole, air inlet box, and the inner cavity of the conical dropper are connected.

[0017] In this technical solution, it is ensured that external gas can enter the inner cavity of the conical dropper through the air inlet pipe, air inlet seat, air inlet hole, and air inlet box.

[0018] In the above technical solution, further, the periphery of the blocking block abuts against the air inlet of the air inlet pipe, and the diameter of the plastic ball is larger than the inner diameter of the outlet.

[0019] In this technical solution, the blocking block can seal the air inlet of the air inlet pipe, and the plastic ball can seal the outlet.

[0020] In the above technical solution, the cross-section of the diverter disk is an isosceles trapezoidal structure, and the annular groove is connected to the intake valve.

[0021] In this technical solution, the flow distribution disc is designed to distribute the liquid, ensuring that air can enter the intake valve through the annular groove.

[0022] The beneficial effects of this utility model are:

[0023] This conical dripping funnel, through the coordinated design of an air inlet valve, plastic ball, round rod, blocking block, annular groove, air inlet valve, air inlet pipe, air inlet hole, air filter membrane, air inlet box, and scale lines, ensures that air can enter the inner cavity of the conical dripping bottle when the air inlet valve is pressed, while also preventing impurities in the air from entering the conical dripping bottle. It can also precisely control the amount of liquid entering, and at the same time, achieve a certain degree of uniform mixing of the liquid. Attached Figure Description

Additionally, features described with reference to certain examples may be combined in other examples. Example 1:

[0038] Please see Figure 1 - Figure 7 As shown, this embodiment provides a conical dripping bucket, including:

[0039] A conical dripping bottle 1 has a dripping funnel cover 2 fixedly installed on its top. A diverter disc 4 is fixedly installed at the bottom of the dripping funnel cover 2 and inside the conical dripping bottle 1. An air inlet box 5 is fixedly installed on the diverter disc 4. An air inlet seat 6 is provided inside the air inlet box 5. An air inlet pipe 7 fixedly installed inside the air inlet seat 6 and fixed to the dripping funnel cover 2 is provided. An air inlet hole 8 is opened inside the air inlet seat 6 and below the air inlet pipe 7. An air filter membrane 9 is fixedly installed inside the air inlet seat 6 and at the bottom of the air inlet hole 8.

[0040] A round rod 10 is slidably installed inside the air inlet pipe 7. The top end of the round rod 10 passes through the top of the air inlet pipe 7 and the dripping cup cover 2 and is fixedly installed with an air inlet valve 12. A blocking block 11 is fixedly installed on the periphery of the round rod 10 and inside the air inlet pipe 7. An annular groove 13 is opened on the top of the dripping cup cover 2. A discharge port 14 is opened at the bottom of the conical dripping bottle 1. A plastic ball 15 is provided inside the conical dripping bottle 1 and at the top of the discharge port 14.

[0041] Among them, the air inlet valve 12 provides an air inlet switch for the infusion channel, breaking the vacuum chamber formed by the air inlet valve 12 and the plastic ball 15, so that the liquid can flow smoothly into the conical dropper bottle 1 through the infusion pipeline;

[0042] By pressing the air inlet valve 12, the air inlet valve 12 supports and cooperates with the plastic ball 15 inside the conical drip bottle 1 to achieve a seal inside the cavity, so that gravity infusion cannot be performed in the upper infusion line.

[0043] Manually pressing the air inlet valve 12 causes it to move downwards, which in turn moves the round rod 10 and the blocking block 11 downwards until the blocking block 11 is far from the air inlet of the air inlet pipe 7. At this time, outside air will sequentially pass through the annular groove 13, the air inlet valve 12, the air inlet pipe 7, the air inlet hole 8, the air filter membrane 9, and the air inlet box 5 into the inner cavity of the conical dropper bottle 1. At the same time, the air filter membrane 9 can filter the incoming air to prevent impurities in the air from entering the conical dropper bottle 1. At this time, the sealing system... When the liquid is broken, it enters the conical dropper bottle 1 by gravity. During the liquid entry process, the liquid in the feed pipe 3 will flow to the top of the distribution disc 4. The distribution disc 4 can divide the liquid, so that the liquid on the distribution disc 4 can flow evenly from the periphery of the distribution disc 4 into the inner cavity of the conical dropper bottle 1. This can effectively ensure that the plastic ball 15 is floated smoothly, and at the same time, it can achieve a certain degree of uniform mixing of the liquid. After the infusion is completed, the plastic ball 15 can seal the outlet 14 to prevent the pipeline from dripping dry. Example 2:

[0045] The discharge pipe 16 is fixedly installed at the bottom of the conical dropper 1. The conical dropper 1 has a scale line 17 engraved on one side and the feed pipe 3 is fixedly installed at the top of the conical dropper 1.

[0046] First, the feed pipe 3 is connected to the infusion pipeline, and the discharge pipe 16 is connected to the lower infusion pipeline. The air inlet valve 12 provides an air inlet switch for the infusion channel, breaking the vacuum chamber formed by the air inlet valve 12 and the plastic ball 15. The liquid then flows smoothly into the conical dropper 1 through the infusion pipeline. During the liquid infusion process, personnel can visually observe the scale line 17 to accurately control the amount of liquid entering the bottle. Example 3:

[0047] This embodiment provides a conical dripping bucket, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the discharge pipe 16 is connected to the discharge port 14, and the feed pipe 3 is connected to the inner cavity of the conical dripping bottle 1.

[0050] This ensures that external gas can enter the inner cavity of the conical dropper 1 through the air inlet pipe 7, air inlet seat 6, air inlet hole 8, and air inlet box 5. Example 5:

[0051] This embodiment provides a conical dripping bucket, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the periphery of the blocking block 11 abuts against the air inlet of the air inlet pipe 7, and the diameter of the plastic ball 15 is larger than the inner diameter of the discharge port 14.

[0052] Specifically, the blocking block 11 can seal the air inlet of the air inlet pipe 7, and the plastic ball 15 can seal the outlet 14. Example 6:

[0053] This embodiment provides a conical dripping bucket, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the cross-section of the diversion disk 4 is an isosceles trapezoidal structure, and the annular groove 13 is connected to the air inlet valve 12.

[0054] Specifically, the diversion disc 4 is designed to divert liquids, ensuring that air can enter the intake valve 12 through the annular groove 13.

[0055] It is worth noting that the air inlet valve 12 is made of silicone, and the conical dropper 1 is made of transparent material, to ensure the structural stability of the air inlet valve 12 and the conical dropper 1.

[0056] Working principle: First, connect the feed pipe 3 to the upper infusion pipeline and the discharge pipe 16 to the lower infusion pipeline. The air inlet valve 12 provides an air inlet switch for the infusion channel, breaking the vacuum chamber of the air inlet valve 12 and the plastic ball 15, so that the liquid can flow smoothly into the conical dropper 1 through the infusion pipeline.

[0057] By pressing the air inlet valve 12, the air inlet valve 12 supports and cooperates with the plastic ball 15 inside the conical drip bottle 1 to achieve a seal inside the cavity, so that gravity infusion cannot be performed in the upper infusion line.

[0058] Manually pressing the air inlet valve 12 causes it to move downwards, which in turn moves the round rod 10 and the blocking block 11 downwards until the blocking block 11 is far from the air inlet of the air inlet pipe 7.

At the same time, the air filter membrane 9 can filter the incoming air to prevent impurities in the air from entering the conical dropper bottle 1. At this time, the sealing system is broken, and the liquid flows into the conical dropper bottle 1 by gravity. During the liquid inlet process, personnel can visually observe the scale line 17 to precisely control the amount of liquid entering the pipe. During the liquid inlet process, the liquid in the feed pipe 3 will flow to the top of the distribution disc 4. The distribution disc 4 can divide the liquid, so that the liquid on the distribution disc 4 can flow evenly from the periphery of the distribution disc 4 into the inner cavity of the conical dropper bottle 1. This can effectively ensure that the plastic ball 15 is floated smoothly, and at the same time, it can achieve a certain degree of uniform mixing of the liquid. After the infusion is completed, the plastic ball 15 can seal the outlet 14 to prevent the pipeline from dripping dry.
