Description

Technical Field

[0001] This utility model relates to a safety cap for waste liquid collection, and more particularly to a controllable funnel-type safety cap structure for waste liquid collection. Background Technology

[0002] Chemical researchers generate chemical waste liquids during experiments in chemistry labs, such as toxic and hazardous liquids like methanol, ethanol, isopropanol, and n-hexane. These waste liquids cannot be disposed of arbitrarily; without proper treatment, they can seriously endanger the lives of laboratory personnel. The standard practice in laboratories is to collect the waste liquids in chemical waste collection containers for later centralized processing.

[0003] Currently, chemical laboratories generally use glass or plastic chemical waste collection containers to collect chemical waste. When it is necessary to collect chemical waste, the laboratory personnel manually open the container lid to expose the opening, pour the chemical waste into the chemical waste collection container from the open opening, and then manually tighten the lid on the opening to collect the chemical waste.

[0004] However, the openings of existing chemical waste collection containers are generally relatively small, making it easy to spill when pouring chemical waste into them, thus contaminating laboratory surfaces or floors. Furthermore, the relatively small openings slow down waste collection, making it time-consuming and labor-intensive. Especially when collecting chemical waste containing solid residues, it is necessary to first separate the solids and liquids before filtering out the solid residues and pouring the waste into the collection container, which inevitably increases the workload of laboratory personnel.

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0049] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0050] In some embodiments, such as Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, a controllable funnel-type waste liquid collection safety cap structure is provided. The cap structure mainly includes a cap body 100, a waste liquid collection funnel 200, a press-type closure device 300, and a liquid level float 400 arranged coaxially. The waste liquid collection funnel 200 is installed on the top of the cap body 100.

[0051] To achieve rapid and safe collection of chemical waste liquid, a waste liquid collection funnel 200 is installed on the top of the bottle cap body 100. The large opening at the top of the waste liquid collection funnel 200 makes it easy for laboratory personnel to pour the waste liquid into the waste liquid collection funnel 200, avoiding the problem of directly pouring the waste liquid into the opening of the small-diameter chemical waste liquid collection bucket, and thus avoiding the problem of easy spillage when pouring chemical waste liquid into the bucket opening, ensuring that the laboratory table or floor is not contaminated.

[0052] To collect chemical waste containing solid residue, a press-type closure 300 is fixedly installed inside the waste collection funnel 200, and its lower end is detachably installed in the inner hole of the bottle cap body 100 through a filter plate 305. The filter plate 305 has several filter holes 306, through which the chemical waste is separated into solid and liquid. The chemical waste with solid residue removed is then poured into the chemical waste collection bucket, and the filter residue on the filter plate 305 is collected and cleaned.

[0053] The push-button closure 300 is coaxially mounted in the inner holes of the bottle cap body 100 and the waste liquid collection funnel 200, while the liquid level float 400 is coaxially and movably mounted in the inner hole of the push-button closure 300. The float 402 at the lower end of the liquid level float 400 is located below the bottle cap body 100 and extends into the waste liquid container. The liquid level indicator column 403 at the top can be raised and lowered and is hidden in the inner hole at the top of the push-button closure 300. During use, the liquid level float 400 can rise and fall with the change in the liquid level in the waste liquid container, thereby driving the rise and fall of the liquid level indicator column 403 to achieve the purpose of liquid level indication, promptly reminding the experimenter to stop pouring waste liquid and preventing waste liquid overflow.

[0054] In some of these embodiments, such as Figure 4 , Figure 5 and Figure 6 As shown, the bottle cap body 100 mainly includes a lower cap body 101 and an upper cap body 102. The upper cap body 102 is disposed in the through hole at the top of the lower cap body 101, forming an anti-tangle structure design.

[0055] To support the installation of the push-button type closure device 300, an annular support block 103 is integrally provided on the inner circumferential wall of the inner hole of the upper cover 102. The annular support block 103 has several spaced-apart limiting holes 104. Several limiting posts 307 at the bottom of the push-button type closure device 300 can be installed into these limiting holes 104 to limit the movement of the push-button type closure device 300.

[0056] In some of these embodiments, such as Figure 2 , Figure 4 and Figure 5 As shown, the waste liquid collection funnel 200 includes an inverted conical funnel body, a connecting part 201 disposed at the bottom of the inverted conical funnel body, and a sealing part 202 disposed at the bottom of the inner cavity of the inverted conical funnel body.

[0057] Specifically, the connecting part 201 is located at the lower end of the waste liquid collection funnel 200, and it can be threaded onto the upper cover 102 of the bottle cap body 100 to achieve a sealed connection between the waste liquid collection funnel 200 and the bottle cap body 100. The sealing part 202 is formed at the bottom of the inner cavity of the waste liquid collection funnel 200, and its surface is a V-shaped inclined surface with the outer side higher than the inner side relative to the central through hole. The waste liquid in the inverted conical funnel body flows along the V-shaped inclined surface into the central through hole, and then flows downward into the waste liquid tank.

[0058] In some of these embodiments, such as Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the press-type closure 300 includes a central tube 301, a sealing plate 302, and a filter plate 305. The central tube 301 is a hollow tube structure, and the sealing plate 302 and the filter plate 305 are respectively provided on the lower end of the tube.

[0059] like Figure 4 , Figure 10 , Figure 13 and Figure 14 As shown, the sealing plate 302 is located above the filter plate 305 and is used to seal and adhere to the sealing part 202, thereby sealing and opening the bottom through hole of the waste liquid collection funnel 200. To cooperate with the V-shaped inclined surface of the sealing part 202, the upper surface of the sealing plate 302 is an inverted V-shaped inclined surface with the inner side higher than the outer side, and the lower surface is a W-shaped inclined surface with the periphery and center higher than the middle, which cooperates with the sealing part 202.

[0060] like Figure 11 , Figure 12 , Figure 13 and Figure 14 As shown, the filter plate 305 is a mesh structure with several filter holes 306, the diameter of which is slightly smaller than the inner diameter of the upper cover 102, and can be sealed and installed in the inner hole of the upper cover 102. Several limiting posts 307 that cooperate with the limiting holes 104 are provided at intervals on the bottom of the outer periphery of the filter plate 305.

[0061] As one embodiment of the press-type closure 300 for sealing or opening, the filter plate 305 at the lower end of the press-type closure 300 is manually pressed into the inner hole of the upper cover 102. When waste liquid is poured into the funnel for collection, the bottom limiting posts 307 are manually placed on the peripheral surface of the filter plate 305 instead of being inserted into the limiting hole 104. At this time, the filter plate 305 and the filter plate 305 above it are at the highest point, forming a gap between the filter plate 305 and the sealing part 202. The waste liquid flows into the waste liquid bucket through the gap, thus collecting the waste liquid.

[0062] When the waste liquid tank is full and the level float 400 rises to issue a warning, and there is still a large amount of waste liquid remaining in the waste liquid collection funnel 200, manually rotate the press-type closure 300 to insert the corresponding limiting posts 307 at the bottom into the limiting holes 104. At this time, the filter plate 305 and the filter plate 305 above it are at the lowest point, and the bottom of the filter plate 305 is attached to the sealing part 202, thereby sealing the bottom through hole of the waste liquid collection funnel 200, thus preventing the waste liquid from continuing to flow into the waste liquid tank, avoiding the waste liquid overflowing from the waste liquid collection tank, and ensuring the safety of operation.

[0063] like Figure 4 , Figure 5 , Figure 8 , Figure 10 , Figure 12 and Figure 14As shown, as another preferred embodiment of the press-type closure 300 for sealing or opening, in order to achieve automatic sealing and opening of the bottom through hole of the waste liquid collection funnel 200, the press-type closure 300 further includes an inner press plug 303 and an outer press plug 304. The inner press plug 303 is disposed at the lower end of the central tube 301, and the bottom of the outer press plug 304 is fixedly connected to the filter plate 305;

[0064] The inner pressing plug 303 is movably disposed within the inner hole of the outer pressing plug 304, and the two are connected by a conventional locking mechanism. When the inner pressing plug 303 is pressed, it moves vertically relative to the outer pressing plug 304 to occupy two switch positions. As one embodiment, the locking mechanism can be the one described in CN113585408A, the difference being that a through-hole channel for mounting the float 401 is provided at the central axis position of the locking mechanism.

[0065] Through the design of the locking mechanism between the inner plug 303 and the outer plug 304, when the middle tube 301 is pressed downwards and locked onto the outer plug 304 at its lowest position, the sealing plate 302 on the middle tube 301 is also at its lowest position, fitting snugly against the sealing part 202 for sealing. When the tube 301 is pressed downwards again, the tube 301 pops upwards under the action of the return spring of the locking mechanism, simultaneously causing the sealing plate 302 to move upwards and disengage from the sealing part 202, thereby opening the through hole at the bottom of the funnel.

[0066] In addition, such as Figure 4 and Figure 10 As shown, the inner plug 303 is a hollow structure, and its inner cavity is connected vertically to the inner cavity of the middle tube 301 to form a floating channel for the liquid level float 400 to pass through.

[0067] In some of these embodiments, such as Figure 3 , Figure 7 , Figure 9 , Figure 11 , Figure 12 , Figure 13 and Figure 14 The diagram shows two working states of the liquid level float 400: a low, non-warning position and a high, warning position. The push-button type shut-off device 300 also includes a limiting square groove 308 and a pressing plate 309. There is at least one limiting square groove 308, which is formed on the upper end of the tube body 301 to limit the connection of the liquid level float 400. The pressing plate 309 is a hollow annular structure, with its bottom coaxially set at the top of the tube body 301, and its upper surface is flat, making it easy to press manually.

[0068] In some of these embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 11 , Figure 12 , Figure 13 and Figure 14 As shown, the liquid level float 400 includes a float rod 401, a float 402, and a liquid level indicator column 403. The float rod 401 is coaxially inserted into the floating channel of the push-type closure device 300, with its lower end connected to the float 402 and its top end connected to the liquid level indicator column 403.

[0069] In addition, the level float 400 also includes a limiting crossbar 404, which is located at the upper end of the float 401, and its outer end is limited in the limiting square groove 308 on the upper end of the middle tube 301.

[0070] In some of these embodiments, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the bottle cap structure may also include a sealing top cover 500 as needed. The sealing top cover 500 is detachably and sealingly installed at the opening of the waste liquid collection funnel 200, and a handle is provided on its top for easy removal and placement.

[0071] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
