Description

Technical Field

[0001] This utility model relates to the field of laboratory equipment, and in particular to a laboratory waste liquid collection device. Background Technology

[0002] In daily laboratory work, waste liquids with unpleasant odors are generated, which can cause discomfort to the human body. Therefore, the collection of these waste liquids is particularly important.

[0003] Chinese Patent Publication No. CN220165893U discloses a mobile waste liquid collector. It has a hemispherical plug structure that can elastically slide along its axis in the collection tank. When waste liquid enters the collection tank, the hemispherical plug structure can be pressed by the gravity and impact of the waste liquid to open the channel between the collection tank and the collection bucket, thus forming a flow channel gap between the tank and the bucket, allowing the waste liquid to enter the collection bucket. When the waste liquid does not need to be poured out, the hemispherical plug structure can be reset under the action of the elastic element to close the channel between the collection tank and the collection bucket, thereby preventing the odor from escaping from the collection bucket.

[0004] However, the above-mentioned device still has certain shortcomings:

[0005] When there is a large amount of waste liquid, the hemispherical plug structure cannot fully open the channel opening, but can only form a flow channel gap with the channel opening. There is a possibility of overflow due to the waste liquid not being discharged in time. It is necessary to pour it out in batches multiple times to avoid this situation, which is very inconvenient to operate.

[0006] In addition, when a small amount of waste liquid is poured out at one time, the impact force generated by the waste liquid and its own weight cannot overcome the elastic force of the elastic element, resulting in the accumulation of waste liquid inside the collection tank. Therefore, this will still cause odor to be emitted, which in turn will cause discomfort to the human body.

[0007] Therefore, a laboratory waste collection device is needed to solve the above problems. Utility Model Content

[0008] The purpose of this invention is to provide a laboratory waste liquid collection device that can isolate odors while facilitating the discharge of waste liquid when there is a large amount of waste liquid, and preventing waste liquid accumulation when there is a small amount of waste liquid, thereby achieving the purpose of ease of use and further improving the odor isolation effect.

[0009] To solve the above-mentioned technical problems, this utility model provides a laboratory waste liquid collection device, including a cylinder, a cover, and a stop-blocking structure;

[0010] The cover is detachably and sealingly installed on the cylinder, and is provided with a liquid inlet communicating with the cylinder;

[0011] The plugging structure includes a movable rod, a plugging head, and an elastic element;

[0012] One end of the movable rod passes through the cover and extends into the inside of the cylinder, and is fixedly connected to the stop head;

[0013] The anti-blocking head is matched with the liquid inlet, and can be separated from the liquid inlet under the action of the movable rod;

[0014] A gap is formed between the other end of the movable rod and the upper surface of the cover;

[0015] The elastic element is sleeved on the outside of the movable rod and located within the gap;

[0016] When the movable rod is not subjected to external force, the stop head can block the liquid inlet under the action of the elastic element.

[0017] Furthermore, the stopper head is configured as a frustum-shaped structure, with its outer diameter increasing from top to bottom.

[0018] Furthermore, the movable rod is configured with a U-shaped structure, and a limit plate is provided at the end of the movable rod away from the stop head;

[0019] The gap is formed between the limiting plate and the upper surface of the cover.

[0020] Furthermore, when the stop-block head is impacted by waste liquid and the movable rod is pressed by external force, the stop-block head can separate from the liquid inlet to form a flow channel gap between it and the liquid inlet for waste liquid to flow.

[0021] Furthermore, when the movable rod is pressed and rotated, the stopper head is misaligned with the liquid inlet, and under the action of the elastic element, the stopper head can be tightly attached to the inner cavity top wall of the cover.

[0022] Furthermore, the liquid inlet is located off-center from the center of the cover, and one end of the movable rod passes through the axis of the cover.

[0023] Furthermore, the cover and the cylinder are connected by threads.

[0024] Furthermore, an annular groove is provided on the outer wall of the end where the cylinder connects to the cover.

[0025] A deformable sealing sleeve is provided inside the annular groove;

[0026] The outer wall of the sealing sleeve has multiple annular protrusions;

[0027] When the cover is connected to the cylinder, the sealing sleeve can be squeezed to deform the multiple annular protrusions so that they fit tightly against the inner wall of the cover, thereby forming multiple sets of sealing pairs.

[0028] Furthermore, the sealing sleeve is configured as a corrugated tubular structure.

[0029] Furthermore, the cover is provided with a liquid inlet funnel that communicates with the liquid inlet.

[0030] Compared with the prior art, the present invention has at least the following beneficial effects:

[0031] By incorporating a stop-blocking structure including a stop-blocking head, a movable rod, and an elastic element, when a large amount of waste liquid is poured, pressing and rotating the movable rod can misalign the stop-blocking head with the inlet to fully open the inlet, creating a large flow channel for rapid waste liquid discharge. When the amount of waste liquid is small, or the impact of the waste liquid and gravity cannot overcome the elastic force of the elastic element, the operator can manually press the movable rod to separate the stop-blocking head from the inlet, creating a flow channel gap to ensure smooth flow of waste liquid into the cylinder. Simultaneously, the elastic element drives the stop-blocking head to automatically seal the inlet when there is no external force, effectively preventing odor emission and waste liquid overflow, thus achieving the purpose of isolating odor emission while also facilitating use.

[0037] The laboratory waste liquid collection device of this utility model will now be described in more detail with reference to the schematic diagrams, which illustrate preferred embodiments of this utility model. It should be understood that those skilled in the art can modify the utility model described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the utility model.

[0038] Furthermore, based on the teachings of this specification, those skilled in the art can form new technical solutions through cross-combination of different implementation methods without creating technical contradictions. Such variations should all be considered to fall within the protection scope of this patent.

[0039] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0040] like Figures 1 to 4 As shown in the figure, this utility model embodiment proposes a laboratory waste liquid collection device, including a cylinder 1, a cover 2, and a stop-blocking structure 3.

[0041] The cover 2 is detachably and sealed on the cylinder 1 and is provided with a liquid inlet 21 that communicates with the cylinder 1. By providing the liquid inlet 21, the operator can discharge waste liquid into the cylinder 1 through the liquid inlet 21.

[0042] The stop structure 3 includes a movable rod 31, a stop head 32, and an elastic element 33.

[0043] One end of the movable rod 31 passes through the cover 2 and extends into the interior of the cylinder 1, and is fixedly connected to the stop head 32. That is, by setting the movable rod 31, the stop head 32 is moved.

[0044] Specifically, the stopper head 32 is matched with the liquid inlet 21, and can be separated from the liquid inlet 21 under the action of the movable rod 31.

[0045] It should be noted that in this embodiment, the movable rod 31 is movable, that is, the movable rod 31 can move relative to the cover 2 in the height direction and rotate around the height direction, so that the stop head 32 can be separated from the liquid inlet 21 while the liquid inlet 21 can be fully opened. For example, when the movable rod 31 is pressed and rotated, the stop head 32 and the liquid inlet 21 can be misaligned, thereby fully opening the liquid inlet 21. This allows the liquid inlet 21 to be fully opened for discharge when a large amount of waste liquid needs to be discharged, without the need for multiple discharges, thus achieving the purpose of convenient use.

[0046] A gap is formed between the other end of the movable rod 31 and the upper surface of the cover 2.

[0047] The elastic element 33 is sleeved on the outside of the movable rod 31 and located in the gap, and is used to drive the movable rod 31 to reset so as to drive the stop head 32 to fit tightly with the liquid inlet 21.

[0048] Specifically, when the movable rod 31 is not subjected to external force, the stop head 32 can block the liquid inlet 21 under the action of the elastic element 33.

[0049] This device employs a stop-blocking structure 3 comprising a stop-blocking head 32, a movable rod 31, and an elastic element 33. When a large amount of waste liquid is poured, pressing and rotating the movable rod 31 causes the stop-blocking head 32 to be misaligned with the inlet 21, fully opening the inlet 21 and creating a large flow channel for rapid waste liquid discharge. When the waste liquid is small, or the impact of the waste liquid and gravity cannot overcome the elastic force of the elastic element 33, the operator can manually press the movable rod 31 to separate the stop-blocking head 32 from the inlet 21, creating a flow channel gap and ensuring smooth flow of waste liquid into the cylinder 1. Simultaneously, the elastic element 33 automatically seals the inlet 21 when there is no external force, effectively preventing odor emission and waste liquid overflow. This achieves the goal of isolating odor emission while also facilitating use.

[0050] In this embodiment, a method of using the device is also proposed to better illustrate the technical effects that the device can achieve, as detailed below:

[0051] During normal use, the operator only needs to pour the waste liquid into the inlet 21. Under the impact of the waste liquid and its own weight, a flow channel gap is formed between the anti-blocking head 32 and the inlet 21, thus completing the discharge of the waste liquid.

[0052] When there is a small amount of waste liquid or a small amount of waste liquid remains after the waste liquid has been poured out, which is insufficient to overcome the elastic force of the elastic element 33, the operator presses the movable rod 31 to form a flow channel gap between the stop head 32 and the liquid inlet 21, so as to avoid the accumulation of waste liquid.

[0053] When there is a large amount of waste liquid, the operator presses the movable rod 31 to completely separate the stop head 32 from the inlet 21, and then rotates the movable rod 31 to make the stop head 32 and the inlet 21 misaligned. At this time, under the action of the elastic element 33, the stop head 32 can be tightly attached to the inner cavity top wall of the cover 2, thereby realizing the complete opening of the inlet 21, forming a large-size flow channel to realize the rapid discharge of waste liquid, without the need to complete the waste liquid dumping in batches, thus achieving the purpose of convenient operation.

[0054] It should be noted that in this embodiment, the elastic element 33 and the movable rod 31 are connected in a non-fixed manner. The elastic element 33 only serves to reset the movable rod 31 and will not interfere with the rotation of the movable rod 31.

[0055] Among them, the elastic element 33 is set as a compression spring.

[0056] To improve the odor isolation effect, the shape of the anti-blocking head 32 is further defined. Specifically, the anti-blocking head 32 is configured as a frustum-shaped structure with an increasing outer diameter from top to bottom to increase the contact area with the liquid inlet 21, thereby improving the odor isolation effect.

[0057] Preferably, the outer wall of the plug head 32 is provided with a sealing ring to further enhance the odor isolation effect.

[0058] In this embodiment, the movable rod 31 is configured with a U-shaped structure, and a limiting plate 311 is provided at the end of the movable rod 31 away from the stop head 32. The limiting plate 311 forms the gap with the upper surface of the cover 2. That is, the elastic element 33 and the limiting plate 311 are not fixedly connected; they are only elastically fitted together and will not interfere with the rotation of the movable rod 31.

[0059] In this embodiment, when the stop-block head 32 is impacted by waste liquid and the movable rod 31 is pressed by external force, the stop-block head 32 can separate from the liquid inlet 21, so as to form a flow channel gap between the stop-block head 32 and the liquid inlet 21 for waste liquid to flow through. This makes it possible to avoid manually pressing the movable rod 31 for a long time when pouring waste liquid under normal conditions. Only after the waste liquid is poured out, the movable rod 31 needs to be pressed to discharge the residual waste liquid, thus achieving the purpose of convenient use.

[0060] In other embodiments, to facilitate operator control of the movement of the movable rod 31, the positions of the movable rod 31 and the liquid inlet 21 are further defined.

[0061] Specifically, the liquid inlet 21 is located at a position off-center from the center of the cover 2, and one end of the movable rod 31 passes through the axis of the cover 2.

[0062] In a further embodiment, the cover 2 and the cylinder 1 are further defined to further enhance the odor isolation effect.

[0063] Specifically, the cover 2 and the cylinder 1 are connected by threads.

[0064] The outer wall of the end where the cylinder 1 connects to the cover 2 is provided with an annular groove 11, and a deformable sealing sleeve 4 is provided in the annular groove 11.

[0065] Furthermore, the outer wall of the sealing sleeve 4 has multiple annular protrusions 41.

[0066] Furthermore, when the cover 2 is connected to the cylinder 1, the sealing sleeve 4 can be squeezed to deform the multiple annular protrusions 41 to fit tightly against the inner wall of the cover 2, thereby forming multiple sets of sealing pairs.

[0067] By setting a sealing sleeve 4 with multiple annular protrusions 41, and making the sealing sleeve 4 deformable when the cylinder 1 is connected to the cover 2, so that the annular protrusions 41 deform and fit tightly against the inner wall of the cover 2, multiple sets of sealing pairs are formed, thereby improving the sealing performance of the connection between the two and further improving the odor isolation effect.

[0068] In one example, the sealing sleeve 4 is configured as a corrugated tubular structure.

[0069] In other embodiments, to facilitate the operation of waste liquid discharge by the operator, a liquid inlet funnel 5 communicating with the liquid inlet 21 is provided on the cover 2.

[0070] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
