Description

Technical Field

[0001] This utility model relates to the field of slide staining tank technology, and in particular to a slide staining tank that facilitates waste liquid collection. Background Technology

[0002] A slide staining tank, also known as a staining cylinder, is a common laboratory instrument used for staining specimens on glass slides or coverslips. For example, Chinese patent CN205844063U discloses a self-flowing slide staining tank. The main body of this tank is designed in a funnel shape, with a drain pipe at the outlet for discharging the staining solution. The drain pipe is also equipped with a clamp to control its flow. After staining, the operator simply needs to open the clamp on the drain pipe to automatically drain the staining solution, eliminating the need for manual pouring. This not only reduces the risk of slide detachment due to slide movement but also minimizes the possibility of operator exposure to hazardous reagents and potential poisoning.

[0003] In existing laboratory staining procedures, the staining wastewater discharged from the staining tank contains biological contaminants (such as tissue specimen residues and microorganisms) and chemical dyes (some containing heavy metals and toxic organic compounds). Therefore, direct discharge must be strictly prohibited according to laboratory regulations. Instead, it must be directed through a drain pipe into a dedicated wastewater collection container with a clearly labeled category. The drain pipe, as a key component for the standardized collection of wastewater, undertakes the task of directional discharge and precise delivery of the wastewater, participating in the entire process of wastewater guidance and collection. This drain pipe primarily relies on the gravity of the wastewater for drainage, requiring the collection container to be placed at a low position to create a gravitational difference to provide flow momentum. However, this method has high requirements for the placement environment; the container must be at a low position and the drain pipe path must be unobstructed. If the site is limited and the height difference cannot be met, it will lead to poor wastewater discharge and inconvenience in wastewater collection. Utility Model Content

[0004] The purpose of this invention is to address the problem that in the existing technology, the waste liquid containing pollutants discharged from the staining tank in the testing laboratory needs to be directed into a special container for standardized treatment through a drain pipe. This drain pipe relies on gravity for drainage, which has the problems of high requirements for the placement environment and limited space, which can easily lead to poor drainage. The invention proposes a slide staining tank that facilitates waste liquid collection.

[0005] The technical solution of this utility model is as follows: a slide staining tank for easy waste liquid collection, comprising a staining tank body and a funnel base disposed at the bottom of the staining tank body, wherein a drain pipe is installed at the bottom of the funnel base, and further comprising: a first one-way valve fixedly connected to the end of the drain pipe away from the funnel base, wherein a suction pipe is fixedly connected to the end of the first one-way valve away from the drain pipe; a suction mechanism disposed in the suction pipe to allow waste liquid in the staining tank body to enter the suction pipe through the drain pipe; and a discharge mechanism installed on the suction pipe corresponding to the first one-way valve, wherein the discharge mechanism and the suction mechanism are linked and switched.

[0006] Optionally, the extraction mechanism includes a telescopic tube slidably connected inside one end of the extraction tube. A push plug is fixedly connected to one end of the telescopic tube inserted into the extraction tube. After the push plug moves away from the drain pipe, it is used to open the first one-way valve and draw the waste liquid in the dyeing tank into the extraction tube.

[0007] Optionally, the extraction mechanism further includes a pressing plate fixedly connected to the end of the telescopic tube away from the push plug, and a return spring is movably sleeved at the end of the telescopic tube near the pressing plate.

[0008] Optionally, a pair of finger hook plates corresponding to the pressing plate are fixedly connected to the outer wall of the end of the extraction tube away from the first one-way valve.

[0009] Optionally, the outer wall of the push plug is fitted with a pair of sealing rings that fit tightly against the inner wall of the extraction tube.

[0010] Optionally, a limiting block that locks the push plug is fixedly connected inside one end of the extraction tube near the first one-way valve.

[0011] Optionally, the liquid discharge mechanism includes a liquid outlet hole opened at one end of the discharge pipe near the first one-way valve, a connecting pipe aligned with the liquid outlet hole is fixedly connected to one end of the discharge pipe, a second one-way valve corresponding to the first one-way valve is fixedly connected to the end of the connecting pipe away from the discharge pipe, and a liquid outlet pipe is fixedly connected to the end of the second one-way valve away from the connecting pipe.

[0012] Optionally, the opening end cap of the dyeing tank body is provided with a top cover, the bottom of the funnel base is fixedly connected with a connecting protrusion that is fixedly sleeved with the end of the drain pipe, and the bottom of the dyeing tank body is fixedly connected with a plurality of support legs arranged in a circumferential array.

[0013] In summary, this application includes at least one of the following beneficial technical effects:

[0014] This invention utilizes the cooperation of components such as the staining tank body, the extraction and dispensing mechanism, and the discharge mechanism. When using the slide staining tank, pressing the pressing plate moves the push stopper, allowing the waste liquid in the staining tank body to enter the extraction and dispensing pipe through the funnel base, the drain pipe, and the first one-way valve. After releasing the pressing plate, the return spring moves the push stopper back to its original position, and the waste liquid is discharged directionally into a dedicated container through the outlet hole, the connecting pipe, the second one-way valve, and the outlet pipe. This method eliminates reliance on gravity-based drainage, reduces requirements for the placement environment, avoids drainage problems caused by space constraints, and simultaneously achieves standardized waste liquid collection, reduces the risk of pollution, and improves the efficiency and convenience of waste liquid collection.

[0025] Example

[0026] like Figures 1 to 3 As shown, the slide staining tank proposed in this utility model, which facilitates waste liquid collection, includes a staining tank body 1 and a funnel base 11 disposed at the bottom of the staining tank body 1. The funnel base 11 is funnel-shaped and can collect and guide the staining waste liquid, facilitating its flow into subsequent drainage components. A drainage pipe 2 is installed at the bottom of the funnel base 11, which is the key channel for the waste liquid to be transferred from the staining tank body 1 to the extraction pipe 3. A first one-way valve 21 is fixedly connected to the end of the drainage pipe 2 away from the funnel base 11. The first one-way valve 21 controls the unidirectional flow of waste liquid into the extraction pipe 3, preventing backflow. The extraction pipe 3 is fixedly connected to the end of the first one-way valve 21 away from the drainage pipe 2. The extraction pipe 3 provides space for the movement of the push plug 41 and connects various inlet and outlet components. A limiting block 34 is fixedly connected inside the end of the extraction pipe 3 near the first one-way valve 21 to hold the push plug 41 in place. The limiting block 34 is used to limit the movement range of the push plug 41, preventing excessive movement and damage to components. A pair of finger hook plates 36 corresponding to the pressing plate 43 are fixedly connected to the outer wall of the end of the extraction pipe 3 away from the first one-way valve 21. The finger hook plates 36 provide auxiliary support for the operator to operate the pressing plate 43, thereby improving the ease of operation.

[0027] Among them, such as Figures 1 to 3As shown, a suction mechanism is used inside the suction pipe 3. This mechanism allows waste liquid from the dyeing tank body 1 to enter the suction pipe 3 through the drain pipe 2. The suction mechanism includes a telescopic tube 4 slidably connected inside one end of the suction pipe 3. The telescopic tube 4 can extend and retract with the pressing and resetting of the pressing plate 43, causing the push plug 41 to move synchronously. The end of the telescopic tube 4 inserted into the suction pipe 3 is fixedly connected to the push plug 41. The push plug 41 changes the pressure inside the suction pipe 3 by moving, realizing the suction and discharge of waste liquid. A pair of sealing rings 42 are fixedly fitted on the outer wall of the push plug 41, closely adhering to the inner wall of the suction pipe 3. The sealing rings 42 enhance the sealing of the inside of the suction pipe 3, ensuring the pressure regulation effect. After the push plug 41 moves away from the drain pipe 2, it opens the first one-way valve 21, drawing the waste liquid in the dyeing tank body 1 into the extraction pipe 3. The extraction mechanism also includes a pressing plate 43 fixedly connected to the end of the telescopic pipe 4 away from the push plug 41. The pressing plate 43 provides a force application point for the operator, facilitating control of the movement of the push plug 41. A return spring 44 is movably sleeved at the end of the telescopic pipe 4 near the pressing plate 43. The return spring 44 provides elastic restoring force after the pressing plate 43 is released, driving the push plug 41 to return to its original position.

[0028] In addition, such as Figures 1 to 3 As shown, a discharge mechanism corresponding to the first one-way valve 21 is installed on the discharge pipe 3. The discharge mechanism is linked to the discharge mechanism. The discharge mechanism includes an outlet hole 33 at the end of the discharge pipe 3 near the first one-way valve 21, providing an outlet for the waste liquid in the discharge pipe 3 to flow to the connecting pipe 31. One end of the discharge pipe 3 is fixedly connected to the connecting pipe 31 aligned with the outlet hole 33. The end of the connecting pipe 31 away from the discharge pipe 3 is fixedly connected to a second one-way valve 32 corresponding to the first one-way valve 21. When the second one-way valve 32 is closed due to the pressing plate 43, the first one-way valve 21 is simultaneously opened. By sliding the push plug 41 in the discharge pipe 3, the opening and closing states of the two one-way valves can be precisely controlled, and the two always maintain an open-closed coordination mode to ensure smooth flow of fluid in and out of the discharge pipe 3. The second one-way valve 32 ensures that the waste liquid in the discharge pipe 3 is discharged unidirectionally to the outlet pipe 35, preventing reverse flow. The second check valve 32 has an outlet pipe 35 fixedly connected to its end away from the connecting pipe 31. The outlet pipe 35 is used to direct the treated waste liquid into a dedicated waste liquid collection container. A check valve, also known as a non-return valve, is an automatic valve that only allows fluids (liquids, gases, etc.) to flow in a preset direction and prevents them from flowing in the opposite direction. It does not require manual or external power control and relies solely on the pressure difference of the fluid itself to open and close.

[0029] It is worth noting that, such as Figure 1As shown, the opening end cap of the staining tank body 1 is equipped with a top cover 13, which prevents waste liquid from splashing during the staining process and reduces the entry of external contaminants into the tank. A connecting protrusion 12 is fixedly connected to the bottom of the funnel base 11, which is fixedly sleeved to the end of the drain pipe 2. The connecting protrusion 12 is used to fix the funnel base 11 and the drain pipe 2, establishing a connecting channel for waste liquid transmission. Multiple support legs 14 arranged in a circular array are fixedly connected to the bottom of the staining tank body 1. The support legs 14 are used to stably support the staining tank body 1 on the experimental platform, ensuring operational stability.

[0030] In this embodiment, when using a slide staining tank that facilitates waste liquid collection, the staining tank body 1 is first placed stably on the experimental table using the support legs 14. Covering it with the top cover 13 prevents waste liquid from splashing during the staining process. After staining is completed, the pressing plate 43 on the extraction tube 3 is operated to push the telescopic tube 4, causing the push plug 41 to move into the extraction tube 3. The return spring 44 is compressed and shortened, storing force. At this time, the pressure change in the extraction tube 3 will cause the second one-way valve 32 to open, while the first one-way valve 21 will close, until the push plug 41 abuts against the limit block 34. At this time, the push plug 41 moves to its limit in the extraction tube 3, and the pressing plate 43 can be released. The pressing plate 43, through the elastic rebound of the return spring 44, drives the telescopic tube 4 and the push plug 41 to move. At this time, the second one-way valve 32 is closed, but the first one-way valve 21 will open. Subsequently, the waste liquid in the staining tank body 1 is collected by the funnel base 11 and enters the extraction tube 3 in sequence through the connecting convex tube 12, the drain tube 2, and the first one-way valve 21. The sealing ring 42 on the pusher 41 ensures the airtightness of the inside of the extraction pipe 3, and the limiting block 34 restricts the movement range of the pusher 41 to prevent excessive movement and damage to the components. Repeatedly pressing the pressing plate 43 allows the waste liquid in the dyeing tank body 1 to enter the extraction pipe 3 and then be discharged from the outlet pipe 35, ultimately flowing into a dedicated waste liquid collection container. The finger hook plate 36 provides auxiliary support for operators when operating the pressing plate 43, improving operational convenience. The entire process, through the coordinated operation of various components, eliminates the reliance on gravity drainage, achieving efficient and convenient collection of waste liquid.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
