Description

Technical Field

[0001] The utility model relates to the technical field of dyeing liquid dripping, in particular to a dyeing liquid quantitative dripping device. Background Art

[0002] In the existing manual dyeing process, multiple dyeing solutions are mostly used to perform composite dyeing in sequence. For example, the Gram staining method requires four different dyeing solutions.

[0003] The use of commercial test kits with existing dyeing liquids is mostly to squeeze out the dyeing liquid by manually squeezing the bottle body to increase the pressure inside the bottle body. In this operation, even the experimental personnel with skilled technical skills often cause insufficient or excessive addition of dyeing liquid due to uneven pressing strength, making it impossible to control the amount of dyeing liquid to be added in the next step, wasting the dyeing liquid and causing the remaining amount of each dyeing liquid in the multiple dyeing liquid test kit set to be uneven. After one bottle of dyeing liquid is exhausted, even if other dyeing liquids are remaining, the entire batch has to be discarded; secondly, different dyeing liquids cannot achieve the amount of dyeing ratio required by the test kit, resulting in unsatisfactory dyeing effect; in addition, the packaging bottles of existing commercial dyeing liquid test kits on the market are mostly foldable and hidden liquid outlets. After several uses, the dyeing liquid overflows to the bottle mouth and bottle body, and even flows to the laboratory table, and will dirty the gloves when held in the hand. Some dyeing liquids can even pass through the gloves to color the palm skin, causing unnecessary trouble.

[0004] After searching, the Chinese utility model patent with publication number CN203772625U discloses a new type of sample adding and dyeing device for a slide dyeing machine, including a mounting base plate, a first motor, a second motor and a third motor are arranged on the mounting base plate, the output end of the second motor is vertically connected to the second motor transmission positioning device upward, and a row of several vertically placed syringes are fixedly arranged on the mounting base plate in the horizontal direction, the piston handle of the syringe is transmission-connected to the second motor transmission positioning device, and the lower end of each syringe is inserted into a rubber connection interface and airtightly connected thereto. The application uses a mechanical structure to operate the syringe to achieve the suction and dripping of the dyeing liquid. Although the device can drip the dyeing liquid more efficiently by installing multiple syringes at the same time, since the suction of all syringes is synchronously controlled, it is impossible to use different dyeing liquids in sequence, so the dyeing effect that can be achieved by the device is limited, and it is difficult to meet the use requirements of composite dyeing.

[0025] Example 1

[0026] Refer to the attached Figure 1-2The present application provides a quantitative dyeing liquid dripping device, including a base 1 and a plurality of nozzle bottles 901. The nozzle bottles 901 are used to hold the dyeing liquid. Therefore, the corresponding number of nozzle bottles 901 can be selected according to the type of dyeing liquid required for dyeing, and then the plurality of nozzle bottles 901 can be placed in the rotating drum 9 for storage. Since the vacuum pump in the nozzle bottle 901 has the effect of pressing and quantitatively releasing the material, the dyeing liquid can be quantitatively released by squeezing the nozzle bottle 901. A storage mechanism is provided at one side of the top of the base 1. The storage mechanism is used to place a plurality of nozzle bottles 901 at the same time. The storage mechanism includes a rotating drum 9 and a cylinder cover 11. The cylinder cover 11 is adapted to the rotating drum 9. A groove is provided on the outer side of the top of the rotating drum 9 for limiting the nozzle of the nozzle bottle 901. When placing the nozzle bottle 901, it is only necessary to place its nozzle in the groove to prevent the nozzle from deflecting during the deflection adjustment process of the nozzle bottle 901, thereby ensuring that the nozzle and the support plate 12 In order to achieve the accurate alignment effect, a discharging mechanism is arranged inside the base 1, and the discharging mechanism is used to push the squeezing nozzle bottle 901 to discharge the dyeing liquid. The discharging mechanism includes a driving assembly and a lifting assembly. The lifting assembly includes a threaded sleeve 4 and a threaded rod 18. The threaded sleeve 4 is threadedly connected to the top of the rod body of the threaded rod 18. The threaded sleeve 4 can be lifted or lowered by rotating the threaded rod 18, so the threaded rod 18 can control the threaded sleeve 4 to rise to push the squeezing nozzle bottle 901. The driving assembly includes a joystick 3. A limiting groove is arranged on the other side of the top of the base 1, and the joystick 3 is in the limiting groove. Since the moving distance of the joystick 3 will be limited by the limiting groove, the threaded rod 18 is used to drive the rotation of the joystick 3, and the distance of the threaded sleeve 4 rising will also be limited. Therefore, it is only necessary to ensure that the joystick 3 is moved only by the maximum distance in the limiting groove each time, so that the squeezing nozzle bottle 901 can be pushed to produce the same displacement each time, so the amount of dyeing liquid discharged each time can also be kept consistent.

[0027] Preferably, the top of the base 1 is rotatably connected to a connecting pile 5 on one side away from the joystick 3, the rotating drum 9 is fixedly connected to the top of the connecting pile 5, and the top and bottom ends of the rotating drum 9 are fixedly connected to the partition 8, and the plate body of the partition 8 is provided with a plurality of circular openings, and the pressure-spout bottle 901 is adapted to the circular openings, and the circular openings are used to accommodate the pressure-spout bottle 901, that is, when placing the pressure-spout bottle 901, it can be placed into the rotating drum 9 from the circular opening, and at this time, the partition 8 can limit the bottle body of the pressure-spout bottle 901 The pressure blocks 10 are equidistantly fixedly connected to the outer side of the inner wall of the top end of the cylinder cover 11. The number of the pressure blocks 10 is the same as the circular opening and corresponds to each other up and down. The material of the pressure blocks 10 is rubber. The pressure blocks 10 are used to limit the pressure nozzle of the pressure nozzle bottle 901, so that when the bottle body is pushed and raised, the pressure nozzle cannot rise further. In this case, relative movement will occur between the pressure nozzle and the bottle body, thereby causing the dyeing liquid in the pressure nozzle bottle 901 to be discharged.

[0028] Preferably, a plurality of slots are equidistantly provided on the outside of the connecting pile 5, and the number of the slots is the same as that of the pressing block 10 and corresponds one to one. A fence 6 is fixedly connected to the top of the base 1 at the outside of the connecting pile 5. The diameter of the fence 6 is smaller than the diameter of the rotating drum 9. The fence 6 can support the rotating drum 9, so that its stability during the rotation adjustment process can be ensured to prevent it from deflecting. A spring sheet 7 is fixedly connected to the inner wall of one side of the fence 6. The spring sheet 7 is curved, and a clamping block 701 is fixedly connected to the end of the spring sheet 7 close to the connecting pile 5. The clamping block 701 is adapted to the slot, and both the clamping block 701 and the slot are hemispherical. Under the elastic force of the spring sheet 7, the clamping block 701 can maintain a state of being in close contact with the connecting pile 5 until the rotation of the connecting pile 5 causes the slot to align with the clamping block 701. Then, the clamping block 701 can limit the connecting pile 5 through the slot, thereby fixing the rotating drum 9.

[0029] For example, when using the Gram staining method, the number of the nozzle bottles 901 can be selected to be four, which are used to hold four different dyeing solutions respectively. Similarly, the number of the circular openings on each partition 8 and the card slots on the outside of the connecting pile 5 are also equidistantly set to four. In this case, every time the connecting pile 5 rotates 90 degrees, the connecting pile 5 will be stuck by the block 701 and pause, and a total of four such pauses will occur. Therefore, it is only necessary to correspond each pause to one of the four nozzle bottles 901 and align it with the support plate 12 to ensure the stability of the nozzle bottle 901 during the process of dripping the dyeing solution.

[0030] Preferably, a cavity is provided at a side of the base 1 away from the connecting pile 5, and a rotating rod 16 is rotatably connected between the top and bottom inner walls of the base 1 at the middle of the cavity, and a clockwork spring is fixedly connected between the rotating rod 16 and the base 1, and the clockwork spring is used for resetting the joystick 3 after it is moved, that is, when the joystick 3 is moved from the right end to the left end from the limiting groove, the clockwork spring can return the joystick 3 from the left end to the right end through its own elastic force, and a connecting piece 14 is fixedly connected to the top end of the rod body of the rotating rod 16, and the joystick 3 is fixedly connected to one side of the top end of the connecting piece 14, the limiting groove is arc-shaped, and the center of the limiting groove is on the rotating rod 16, and the connecting piece 14 is the radius of the arc-shaped limiting groove, so the joystick 3 can be moved smoothly in the limiting groove along an arc-shaped trajectory by moving it.

[0031] Preferably, the outer bottom end of the rod body of the rotating rod 16 is connected to the driving wheel 15 through a key, the threaded rod 18 is rotatably connected to one side of the inner wall of the bottom end of the base 1, and the outer bottom end of the rod body of the threaded rod 18 is threadedly connected to the driven wheel 17, the driving wheel 15 is meshed with the driven wheel 17, and the diameter of the driving wheel 15 is much larger than the diameter of the driven wheel 17. The driving wheel 15 with a large diameter is used to drive the driven wheel 17 with a small diameter, which can accelerate the latter. Therefore, a small angle deflection of the driving wheel 15 can cause the driven wheel 17 to rotate a certain number of circles, thereby driving the threaded rod 18 to rotate. The threaded sleeve 4 produces effective lifting and lowering movement. A rectangular opening is provided at the top of the base 1. The threaded sleeve 4 is in a rectangular shape, and the top of the threaded sleeve 4 extends to the outside of the base 1 at the rectangular opening. The rectangular opening can limit the rectangular threaded sleeve 4, that is, limit the rotation of the threaded sleeve 4 so that it can only move in the vertical direction. A circular through hole is provided on the outer side of the bottom end of the rotating drum 9 just below each circular opening. The threaded sleeve 4 extends to the inside of the rotating drum 9 at the circular through hole. When the threaded sleeve 4 rises from the circular through hole to enter the rotating drum 9, it can push the extrusion spout bottle 901 to make the bottle body rise.

[0032] Preferably, the top of the base 1 is fixedly connected with a support rod 2 between the joystick 3 and the rotating drum 9, the top of the support rod 2 is externally sleeved with a sleeve 13, the top of the sleeve 13 is fixedly connected with a support plate 12, the support plate 12 is used to place glass slides, and a plurality of rubber protrusions are equidistantly arranged on the top surface thereof, a threaded through hole is provided at the bottom end of one side of the sleeve 13, and the sleeve 13 is threadedly connected with a bolt at the threaded through hole, after loosening the bolt, the total length of the sleeve 13 and the support rod 2 can be adjusted to adjust the height of the support plate 12, so as to facilitate its accurate alignment with the discharge port on the pressing nozzle.

[0033] Working principle: When the device is in use, multiple nozzle bottles 901 can be used to hold different types of dyeing liquids, and then placed in the rotating drum 9, and the drum cover 11 is covered. At this time, the pressing block 10 and the partition 8 can limit the nozzle and bottle body of the nozzle bottle 901 respectively, thereby ensuring its stability;

[0034] When staining, the glass slide can be placed on the support plate 12, and the height of the support plate 12 can be adjusted by adjusting the total length of the support rod 2 and the sleeve 13 after loosening the bolts. At the same time, the position of the glass slide on the support plate 12 can also be adjusted so that the colored point on its surface can be aligned with the discharge port of the nozzle bottle 901;

[0035] Then, the operating rod 3 can be moved from one end to the other end in the limiting groove in a unidirectional and complete manner. At this time, the operating rod 3 drives the rotating rod 16 to rotate through the connecting piece 14, and the rotating rod 16 drives the driven wheel 17 to rotate through the driving wheel 15. The driven wheel 17 drives the threaded rod 18 to rotate, so that the threaded sleeve 4 can be raised. Therefore, the threaded sleeve 4 can be used to push the nozzle bottle 901, so that the nozzle and the bottle body move relative to each other, and then the dyeing liquid is discharged and dripped onto the glass slide;

[0036] After the dyeing liquid is added, the joystick 3 can be released. At this time, the spring outside the rotating rod 16 can rotate the rotating rod 16 in the opposite direction to restore the original state through its own elastic force. Therefore, the joystick 3 can move in the opposite direction in the limit groove and return to the initial end. At the same time, the threaded sleeve 4 will also drop to restore the original state. After losing the pushing effect of the threaded sleeve 4, the pressure bottle 901 can also gradually restore its original state.

[0037] Afterwards, the rotating drum 9 can be turned to rotate, so the position of the nozzle bottle 901 can be adjusted, so that the nozzle bottle 901 filled with another staining liquid can be aligned with the support plate 12. At this time, the above steps are repeated to drip another staining liquid on the glass slide; and in this process, the block 701 can always maintain a close contact with the connecting pile 5 under the elastic force of the spring sheet 7, and when the connecting pile 5 is rotated to align the outer slot of the block 701 with the block 701, the block 701 can limit the connecting pile 5 through the slot, thereby maintaining the stability of the rotating drum 9.

[0038] Example 2

[0039] See attached Figure 3 The present application provides a quantitative dripping device for dyeing liquid. Compared with Example 1, in order to further stabilize the nozzle bottle 901, a gasket 801 is fixedly connected to each circular opening of the partition 8. The gasket 801 is in a circular shape that is thick on the outside and thin on the inside, and the material of the gasket 801 is rubber. The gasket 801 made of rubber material can cushion the nozzle bottle 901 after it is placed in the circular opening, and its thinner inner edge can adapt to the movement of the nozzle bottle 901 by its own deformation without blocking the movement.

[0040] Working principle: After the spout bottle 901 is placed into the rotating drum 9 through the circular opening on the partition 8, the gasket 801 can replace the partition 8 to contact the spout bottle 901. In this case, the gasket 801 can cushion and protect the spout bottle 901, so as to further ensure the stability and safety of the spout bottle 901. Moreover, since the gasket 801 is in the shape of a circular ring with a thick outside and a thin inside, when its thinner inner edge contacts the spout bottle 901, it will not cause too much obstruction to its movement, but will adapt to its movement through its own deformation.

[0041] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. The protection scope of the utility model should be based on the protection scope of the claims.
