Description

Technical Field

[0001] This utility model relates to the field of laboratory equipment, and in particular to a precision adjustable regenerant spraying device for laboratory use. Background Technology

[0002] A laboratory is a place for scientific research and technological development. It is usually equipped with specialized instruments, equipment and materials for various scientific research activities such as experiments, tests, analysis and synthesis. A regenerator is a substance or mixture used to restore or enhance the performance of a certain material, medium or system. Regenerator spraying refers to the process of uniformly applying the regenerator in the form of mist or fine droplets to the medium or surface to be treated through a spraying device.

[0003] Existing laboratory regenerant spraying methods typically involve using droppers or fixed-volume sprayers. Manual droppers rely on the operator's experience and feel to control the drip rate, which not only increases human error but also limits the reproducibility of experiments. While fixed-volume sprayers improve operational convenience to some extent, their fixed spray rate cannot be flexibly adjusted according to specific experimental needs, limiting their application in complex experimental scenarios and affecting detection efficiency. Furthermore, these traditional devices have complex structural designs, high maintenance costs, and are inconvenient to use.

[0004] Therefore, there is a need to design a laboratory-grade precision adjustable regenerant spraying device that can quantitatively spray regenerant, has a simple structure, facilitates precise dosage control to adapt to different spraying needs, improves detection efficiency and accuracy, reduces maintenance costs, and is easy to use. Utility Model Content

[0005] To overcome the drawbacks of existing laboratory regenerant spraying methods, which typically involve spraying regenerants using droppers or fixed-volume sprayers, this invention provides a laboratory-grade precision adjustable regenerant spraying device that can quantitatively spray regenerants, has a simple structure, facilitates precise dosage control to adapt to different spraying needs, improves testing efficiency and accuracy, reduces maintenance costs, and is easy to use.

[0006] The technical implementation scheme of this utility model is as follows: A laboratory precision adjustable regenerant spraying device includes a body, a threaded head, a piston, a connecting shaft, a tail cap, a connecting plate, a spraying component, and a metering component. The threaded head is connected to the upper left side of the body, and the piston is slidably connected to the inner side of the body. The connecting shaft is connected to the right side of the piston. The tail cap is threadedly connected to the right side of the body. The connecting shaft is slidably connected to the tail cap. The connecting plate is connected to the right side of the connecting shaft. The threaded head is provided with a spraying component for spraying the regenerant, and a metering component for metering the regenerant is provided between the body and the connecting plate.

[0007] More preferably, a handle is provided on the right side of the vessel.

[0008] More preferably, the spraying assembly includes a connector, an adjusting ring, an annular locking block, and atomizing nozzles. The connector is threadedly connected to the threaded head, and the annular locking block is rotatably connected to the left side of the connector. The adjusting ring is connected to the annular locking block and contacts the connector. Multiple atomizing nozzles are connected to the left side of the adjusting ring.

[0009] More preferably, the upper part of the connector has a discharge port.

[0010] More preferably, it also includes an inspection window, which is connected to the upper side of the device.

[0011] More preferably, the quantitative component includes a scale, a limiting ring, a screw, a connecting rod, and a stop block. The scale is connected to the inspection window, and the limiting ring is slidably connected to the body. The front of the limiting ring is threadedly connected to the screw, which contacts the body. The connecting rod is connected to the left side of both the upper and lower parts of the connecting plate, and the stop block is connected to the left side of each connecting rod. The stop blocks are in contact with the limiting ring.

[0012] The beneficial effects are: 1. This utility model moves the limiting ring to the position corresponding to the scale, then rotates the screw in the opposite direction to fix it, and pushes the connecting shaft to move so that the blocking block contacts the limiting ring, thereby pushing out the corresponding amount of regenerant to achieve quantitative spraying. This enables quantitative spraying of regenerant. The structure is simple, it is easy to accurately control the dosage to adapt to different spraying needs, improves the efficiency and accuracy of detection, reduces maintenance costs, and is easy to use.

[0013] 2. When different regenerants are required, the regenerant is added to the device body, and then the adjusting ring and the ring-shaped locking block are rotated to rotate the next atomizing nozzle to the position corresponding to the discharge port. Then the above operation is repeated to spray the regenerant in a quantitative manner. This allows the atomizing nozzle to be switched according to different regenerants, preventing cross-contamination between different regenerants and facilitating the switching of atomizing nozzles.

[0014] 3. This utility model involves pouring the regenerant into the device body through the threaded head, then picking up the connector and contacting it with the threaded head, then rotating the connector for installation. After spraying, the connector is rotated to remove it, and then the tail cap is rotated to remove it. Subsequently, the device body, atomizing nozzle, and connector are cleaned. This allows for the assembly and disassembly of the device body and connector, facilitating the cleaning and replacement of the device body and atomizing nozzle, avoiding the accumulation of residues, and preventing pollution.

[0021] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] A precision adjustable regenerant spraying device for laboratory use, such as... Figures 1-5 As shown, the device includes a body 1, a threaded head 2, a piston 3, a connecting shaft 4, a tail cap 5, a connecting plate 6, an inspection window 7, a scale 8, a connector 9, an adjusting ring 10, an annular locking block 11, an atomizing nozzle 12, a limiting ring 13, a screw 14, a connecting rod 15, and a blocking block 16. The body 1 has a handle on its right side for easy gripping and spraying. The threaded head 2 is connected to the upper left side of the body 1. The piston 3 is slidably connected to the inner side of the body 1. The connecting shaft 4 is connected to the right side of the piston 3. The tail cap 5 is threadedly connected to the right side of the body 1. The connecting shaft 4 is slidably connected to the tail cap 5. The connecting plate 6 is connected to the right side of the connecting shaft 4. The inspection window 7 is connected to the upper side of the body 1 for easy observation of the regenerant usage. The scale 8 is connected to the inspection window 7. The connector 9 is threadedly connected to the threaded head 2. The connector 9 has a discharge port at its upper part for easy regenerant entry and exit.

[0023] The left side of the connector 9 is rotatably connected to the annular locking block 11, and the annular locking block 11 is connected to the adjusting ring 10. The adjusting ring 10 is in contact with the connector 9. Six atomizing nozzles 12 are connected to the left side of the adjusting ring 10. The body 1 is slidably connected to the limiting ring 13. The front of the limiting ring 13 is threadedly connected to the screw 14, and the screw 14 is in contact with the body 1. The left sides of both the upper and lower parts of the connecting plate 6 are connected to the connecting rods 15. The left sides of the connecting rods 15 are connected to the blocking blocks 16, and the blocking blocks 16 are in contact with the limiting ring 13.

[0024] When the laboratory needs to quantitatively spray regenerant, this device can be used. Pick up the device by the handle, then pour the regenerant from the threaded head 2 into the body 1. Next, pick up the connector 9 and align it with the threaded head 2. Then, rotate the connector 9 to install it. After installation, according to the required injection dosage, rotate the screw 14 by the knob. Under the action of the thread, the screw 14 moves and disengages from the body 1. Then, pull the limiting ring 13 by hand to move it to the corresponding position on the scale 8. Then, reverse the direction. Rotating the screw 14 causes it to move in the opposite direction and contact the body 1, thereby fixing the limiting ring 13. Then, by pushing the connecting plate 6, the connecting shaft 4, the piston 3, the connecting rod 15, and the blocking block 16 move, causing the regenerant in the body 1 to flow into the threaded head 2, into the outlet of the connector 9, and then into the adjusting ring 10 and be sprayed out from the corresponding atomizing nozzle 12. This causes the blocking block 16 to contact the limiting ring 13, thereby pushing out the corresponding amount of regenerant to achieve quantitative spraying.

[0025] The regenerant usage can be observed through inspection window 7, allowing for quantitative spraying of the regenerant. The structure is simple, facilitating precise dosage control to adapt to different spraying needs, improving detection efficiency and accuracy, reducing maintenance costs, and providing ease of use. After spraying, the connector 9 is rotated to remove it, followed by the tail cap 5. The device body 1, the atomizing nozzle 12, and the connector 9 are then cleaned. This allows for easy assembly and disassembly of the device body 1 and connector 9, facilitating cleaning and replacement of the atomizing nozzle 12 and preventing residue buildup. To prevent contamination, when different regenerants are needed, the regenerant is added to the body 1, and then the connector 9 is installed. Then, the adjusting ring 10 and the annular locking block 11 are rotated so that the next atomizing nozzle 12 rotates to the position corresponding to the discharge port. The above operation is then repeated to spray the regenerant in a metered manner. This allows for switching between different regenerants by rotating the atomizing nozzle 12, preventing cross-contamination between different regenerants and facilitating the switching of the atomizing nozzle 12. Afterward, the device can be cleaned again.
