Description

Technical Field

[0001] This utility model relates to a self-flowing water rinsing device, and more particularly to a self-flowing water rinsing device for laboratory tubular vessels. Background Technology

[0002] Traditional methods for cleaning tubular glassware (such as graduated pipettes or pipettes) in the laboratory have the following problems:

[0003] Direct injection method: Use a beaker to directly inject gravity-flowing pure water into the top of a pipette or pipette. Due to the small size of the top end of graduated pipettes and pipettes, the surface tension of water makes the injection process difficult. Even if the water flow is thinned before injection, it is difficult to ensure that the pure water completely fills the entire tube, resulting in poor cleaning effect.

[0004] Bulb suction method: Pure water is drawn into the top end of a pipette or tube by using a bulb syringe. This method requires repeated operation 2-3 times, which is not only time-consuming and labor-intensive, but also cannot rinse thoroughly like running water, resulting in low cleaning efficiency.

[0005] Pouring and rinsing method: Pour pure water naturally from above the pipe opening, allowing the water to flow from top to bottom for rinsing. Although this method is simple, it cannot guarantee that the water flow will evenly cover the inner wall of the pipe, making it difficult to thoroughly clean the residue inside the pipe. Utility Model Content

[0006] The purpose of this utility model is to provide a self-flowing water rinsing device for laboratory tubular instruments. It addresses the difficulty of rinsing pure water from graduated pipettes, pipettes, and other tubular instruments in physicochemical laboratories after they have been washed with brushes and detergent. The device uses air pressure and the pressure of the liquid itself to force pure water into the top of the pipette for irrigation or rinsing.

[0007] In view of the purpose of this utility model, the self-flowing water rinsing device of this utility model includes a water storage tank, a cabinet, an automatic water injection system, and an air pressure system. The water storage tank is located on the top of the cabinet. The automatic water injection system is used to inject water into the water storage tank. The bottom of the water storage tank is provided with multiple rubber tubes that connect to the inner cavity of the water storage tank. The bottom end of the rubber tubes is inserted into the top port of the tubular container. Each rubber tube is provided with a water-stop clamp. The top of the cabinet is provided with a drainage groove. The drainage groove is located directly below the tubular container. The bottom of the drainage groove is connected to a drain pipe. A waste liquid bucket is provided below the drain pipe. The air pressure system is used to pressurize air into the space above the inside of the water storage tank to provide air pressure for the self-flowing water of the rinsing device.

[0008] Furthermore, the cabinet includes side panels on both sides and the rear for supporting the water tank, and multiple storage compartments below.

[0009] Furthermore, the automatic water injection system includes a water level sensor, a water injection device, and a control unit. The water level sensor is installed on the water storage tank and is used to monitor the water level inside the tank in real time. The water injection device includes a water injection pipeline and a solenoid valve. One end of the water injection pipeline is connected to a water source, and the other end is connected to the top of the water storage tank. The water injection device controls the water injection pipeline to supply water to the inside of the water storage tank through the solenoid valve. The control unit is used to receive the signal from the water level sensor and control the operation of the water injection device.

[0010] Preferably, the pneumatic system is a foot pedal type, including a foot pedal, a piston, a pneumatic cylinder, and a first connecting air pipe. The piston is connected to the foot pedal via a connecting rod and is installed inside the pneumatic cylinder, moving synchronously with the foot pedal. The pneumatic cylinder is connected to one end of the first connecting air pipe, and the other end of the first connecting air pipe is connected to the top space of the water storage tank. The pneumatic cylinder is located below the side of the cabinet.

[0011] Preferably, the pneumatic system is electric, including an air tank, an electric switch, and a second connecting air pipe. The electric air pump and the air tank are installed on the side of the cabinet and connected to the air tank. One end of the air tank is connected to the second connecting air pipe, and the other end of the second connecting air pipe is connected to the top space of the water tank. The electric switch is installed outside the drain trough and is connected to the electric air pump through a control circuit.

[0012] Compared with the prior art, the present invention has at least the following beneficial effects:

[0013] (1) The self-flowing water rinsing device of this utility model improves the rinsing efficiency and safety of laboratory tubular glassware through the design of an automatic water injection system and a pneumatic system. The combination of the automatic water injection system and the pneumatic system ensures the efficient operation and stable operation of the equipment. The multi-pipe parallel design and the equipment of the waste liquid treatment system further improve the convenience of operation and the cleanliness of the laboratory. The self-flowing water is pressurized into the graduated pipette and pipette by gas, which can clean multiple tubular glassware at one time, saving time and effort. On the other hand, the inside of the tubular glassware is thoroughly cleaned, saving pure water resources. It can be applied to the cleaning of large batches of tubular glassware.

[0014] (2) The automatic water injection system in this embodiment enables water level monitoring and precise control. The water level sensor monitors the water level in the storage tank in real time. When the water level is lower than the set lower limit, the water injection device is automatically activated to ensure that the water level in the storage tank is always sufficient. This not only improves work efficiency but also reduces manual intervention and avoids equipment downtime due to forgetting to add water. The control unit precisely controls the operation of the water injection device to ensure that the water level in the storage tank remains stable within the set range, thus improving the reliability and stability of the equipment.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0025] This application discloses a self-flowing water rinsing device for laboratory tubular glassware, including a water storage tank 1, an automatic water injection system, a cabinet 2 supporting the water storage tank 1, and a pneumatic system. The water storage tank 1 is located at the top of the device and stores up to 4 / 5 of its capacity of pure water. The automatic water injection system injects water into the water storage tank 1. Eight rubber tubes 3 are arranged side-by-side at the bottom of the water storage tank 1, evenly spaced. Each rubber tube 3 is used to insert a graduated pipette 4 (or other tubular glassware with through holes at the top and bottom). The upper end of each rubber tube 3 connects to the inside of the water storage tank 1, and the lower end of each rubber tube 3 is used to connect to the top end of the graduated pipette 4. Each rubber tube 3 is equipped with a water-stop clamp 5 to control the outflow of pure water. The cabinet 2 includes side panels 6 on both sides and the rear for supporting the water tank 1, and multiple storage compartments 7 below. The top of the cabinet 2 is provided with a drain trough 8, which is located directly below the graduated pipe 4. A drain pipe 9 is provided in one of the storage compartments 7, with the top end of the drain pipe 9 connected to the bottom middle position of the drain trough 8. A waste liquid bucket 10 is provided in the storage compartment 7 directly below the drain pipe 9 for collecting the waste liquid after rinsing the graduated pipe 4.

[0026] It is worth noting that the number of rubber tubes 3 in this embodiment can be increased or decreased modularly according to actual conditions and needs.

[0027] In this embodiment, the automatic water injection system includes a water level sensor, a water injection device, and a control unit. The water level sensor is installed on the water storage tank 1 to monitor the water level inside the tank in real time. The water injection device includes a water injection pipe 11 and a solenoid valve 12. One end of the water injection pipe 11 is connected to a water source, and the other end is connected to the top of the water storage tank 1. The water injection device controls the water injection pipe 11 to supply water to the water storage tank 1 via the solenoid valve 12. The control unit receives signals from the water level sensor and controls the operation of the water injection device. When the water level inside the water storage tank 1 is lower than the set lower limit (2 / 5 of the tank's capacity), the water level sensor outputs a signal. Upon receiving the signal, the control unit starts the water injection device, the solenoid valve 12 opens, and water begins to be injected into the tank. When the water level inside the tank reaches the set upper limit (4 / 5 of the tank's capacity), the water level sensor outputs a signal again. Upon receiving the signal, the control unit stops the water injection device, the solenoid valve 12 closes, and the water level inside the tank remains stable.

[0028] For example, the air pressure system is foot-operated. Air is forced into the upper space inside the water tank 1 by human foot pedaling, providing air pressure for the water flowing from the shower device. The pure water in the water tank 1 flows into the graduated pipette 4 connected to the rubber tube 3 under the dual pressure of its own pressure and the air pressure above. The graduated pipette 4 is always kept full of pure water. Waste liquid flows out from the lower end (tip) of the graduated pipette 4 and is guided from the drain trough 8 to the waste liquid bucket 10 in the storage room 7 of the cabinet 2. Specifically, the foot-operated pneumatic system of this embodiment includes a foot pedal 13, a piston, a pneumatic cylinder 14, and a first connecting air pipe 15. The foot pedal 13 has an anti-slip texture to prevent the user from slipping. The piston is connected to the foot pedal 13 via a connecting rod and is installed inside the pneumatic cylinder 14, moving synchronously with the foot pedal 13. The pneumatic cylinder 14 is connected to one end of the first connecting air pipe 15, and the pneumatic cylinder 14 and the first connecting air pipe 15 are used to store and transmit air pressure. The other end of the first connecting air pipe 15 is connected to the top space of the water tank 1. The pneumatic cylinder 14 is located on the lower side of the cabinet 2. When the user steps on the foot pedal 13, the foot pedal 13 drives the piston inside the pneumatic cylinder 14 downwards via the connecting rod. The movement of the piston compresses the air inside the pneumatic cylinder 14, increasing the air pressure. Since the pneumatic cylinder 14 is connected to the top space of the water tank 1, compressed air enters the upper part of the water tank 1 through the first connecting air pipe 15, increasing the air pressure in the top space of the water tank 1. This pressure exerts pressure on the pure water in the water tank 1, forcing the pure water out of the rubber tube 3 at the bottom of the water tank 1 and into the top port of the tubular container, thus achieving the purpose of rinsing the inner wall of the graduated straw 4. When the user releases the foot pedal 13, the piston returns to its original position under the action of the spring installed in the pneumatic cylinder 14, reducing the air pressure in the pneumatic cylinder 14. Consequently, the air pressure in the top space of the water tank 1 also decreases, preparing for the next pedaling action.

[0029] As another example of this utility model, the pneumatic system is electric. An electric air pump 16 pressurizes air into the space above the water tank 1 to provide air pressure for the self-flowing water of the rinsing device. Specifically, the electric pneumatic system also includes an air tank 17, an electric switch 18, and a second connecting air pipe 19. The electric air pump 16 and the air tank 17 are installed on the side of the cabinet 2 and connected to the air tank 17. One end of the air tank 17 is connected to the second connecting air pipe 19, and the other end of the second connecting air pipe 19 is connected to the top space of the water tank 1. The electric switch 18 is installed outside the drain trough 8 and is connected to the electric air pump 16 through a control circuit. During operation, pressing the electric switch 18 activates the electric air pump 16, which compresses air and sends it into the air storage tank 17. The air pressure inside the tank gradually increases. The compressed air then enters the top space of the water storage tank 1 through the second connecting air pipe 19, pressurizing the pure water in the tank and forcing it out through the bottom rubber tube 3. The water then enters from the top port of the tube, achieving the purpose of rinsing the inner wall of the tubular container. After rinsing, the pressure can be released through the exhaust valve on the air storage tank 17.

[0030] It is worth noting that the operation process of the self-flowing water rinsing device of this utility model is as follows: 4 / 5 volume of pure water is injected into the water storage tank 1 through the automatic water injection system. Before injecting water, the water stop clamps 5 on each rubber tube 3 are closed. Then, the graduated pipette 4 or pipette to be rinsed is inserted. Then, the water stop clamps 5 are opened. By operating the air pressure system, the pure water in the water storage tank 1 flows into the tubular container connected to the rubber tube 3 under the dual pressure of its own pressure and the air pressure above. The tubular container is always kept full of pure water. The waste liquid flows out from the lower end (tip) of the tube and flows randomly into the drain trough 8 below. The waste liquid is then guided through the drain pipe 9 to the waste liquid bucket 10 placed in the cabinet 2 for centralized treatment.

If the specific posture changes, the directional indicator will also change accordingly.
