This invention provides a safer and more effective way to classify and recycle laboratory waste liquid, and has wide applicability.

[0004] The aforementioned safety bottle has the effect of classifying and recycling laboratory waste liquids. However, when discharging or transferring waste liquids after collection, the existing safety bottle needs to be tilted or overturned. During this process, the waste liquid is close to the human body, which greatly affects the health and safety of the operator. At the same time, when discharging laboratory waste liquids, the feed hopper of the safety bottle cannot be sealed in time, which may cause the liquid inside the bottle to evaporate. Therefore, there is a need to provide a laboratory waste liquid safety bottle. Utility Model Content

[0005] The purpose of this invention is to provide a laboratory waste liquid safety bottle to solve the problems of existing safety bottles where the waste liquid is too close to the human body during waste liquid discharge or transfer, and the inability to seal the feed hopper of the safety bottle in time when discharging laboratory waste liquid, resulting in the evaporation of the liquid inside the bottle.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a laboratory waste liquid safety bottle, comprising a waste liquid bottle, a feed hopper installed on the upper part of the waste liquid bottle, and a draining mechanism provided on the waste liquid bottle; the draining mechanism includes a suction bottle, which is fixedly installed on the waste liquid bottle, and a suction tube is fixedly installed on the lower part of the suction bottle, and a piston is slidably installed inside the suction bottle, with a suction hole opened in the middle of the piston, and sealing gaskets are rotatably installed on both the piston and the suction tube, with supporting springs fixedly installed between the sealing gaskets, the piston, and the suction tube, a connecting seat fixedly installed on the upper part of the piston, and a suction handle fixedly installed on the upper part of the connecting seat and through the waste liquid bottle, a draining tube fixedly installed on one side of the suction bottle, and a storage tank opened at the bottom of the inner wall of the waste liquid bottle.

[0007] Preferably, the liquid extraction tube is embedded inside the liquid storage tank, and the size of the sealing gasket is consistent with the inner diameter of both the liquid extraction tube and the liquid extraction hole.

[0008] Preferably, slots are provided on both sides of the connector, and the height of the inner wall of the connector is the same as the diameter of the sealing gasket.

[0009] Preferably, the feed hopper is provided with a liquid storage mechanism, the liquid storage mechanism includes a sealing plate, two hinges are fixedly installed in parallel between the sealing plate and the feed hopper, and a lever is fixedly installed on the upper part of the sealing plate. Two support seats are fixedly installed in parallel on the inner wall of the waste liquid bottle, and a buffer spring is fixedly installed between each of the two support seats and the sealing plate.

[0010] Preferably, sealing rings are fitted on both the upper and lower sides of the sealing plate, and the lever is installed on the sealing plate at an angle.

[0011] Preferably, both hinges are located at the lower part of the sealing plate, and both buffer springs are installed at an angle on the lower side of the sealing plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1) This laboratory waste liquid safety bottle, by controlling the pump handle to move up and down repeatedly inside the waste liquid bottle, draws the waste liquid from the waste liquid bottle to the pump bottle under the action of the sealing gasket and flows out through the drain pipe. Thanks to the liquid storage tank inside the waste liquid bottle, the waste liquid can be discharged more thoroughly. The drain pipe is located on the upper side of the waste liquid bottle, so that the waste liquid bottle does not need to be tilted or overturned during discharge, thus maintaining a safe distance between the waste liquid and the operator, greatly increasing the practicality and convenience of the safety bottle.

[0014] 2) This laboratory waste liquid safety bottle uses a hinge to fix the sealing plate to the feed hopper, and the sealing plate is supported by a buffer spring. When waste liquid needs to be added, simply turn the lever on the upper part of the sealing plate to add the waste liquid. When the waste liquid has been added, release the lever to allow the sealing plate to return to its original position under the action of the buffer spring. The sealing plate has sealing rings installed on both the upper and lower sides, which gives the waste liquid bottle good airtightness, thus achieving the effect of rapid liquid addition and sealing of the safety bottle.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Combination Figures 1-5A laboratory waste liquid safety bottle includes a waste liquid bottle 1, a feed hopper 2 installed on the upper part of the waste liquid bottle 1, and a discharge mechanism 3 provided on the waste liquid bottle 1. The discharge mechanism 3 includes a suction bottle 301, which is fixedly installed on the waste liquid bottle 1, and a suction tube 302 is fixedly installed on the lower part of the suction bottle 301. A piston 303 is slidably installed inside the suction bottle 301, and a suction hole 304 is opened in the middle of the piston 303. A sealing gasket 305 is rotatably installed on both the piston 303 and the suction tube 302. A support spring 306 is fixedly installed between the sealing gasket 305, the piston 303, and the suction tube 302. A connecting seat 307 is fixedly installed on the upper part of the piston 303. A suction handle 308 is fixedly installed on the upper part of the connecting seat 307 and through the waste liquid bottle 1. A drain pipe 309 is fixedly installed on one side of the suction bottle 301. A storage tank 310 is opened at the bottom of the inner wall of the waste liquid bottle 1.

[0024] See Figure 3 Furthermore, the liquid extraction tube 302 is embedded inside the liquid storage tank 310, the size of the sealing gasket 305 is consistent with the inner diameter of the liquid extraction tube 302 and the liquid extraction hole 304, the connecting seat 307 has slots on both sides, and the inner wall height of the connecting seat 307 is consistent with the diameter of the sealing gasket 305.

[0025] Specifically, by pushing and pulling the suction handle 308, the piston 303 moves up and down along the inner wall of the waste liquid bottle 1. When the piston 303 moves back and forth, the waste liquid in the waste liquid bottle 1 can be drawn out and discharged through the drain pipe 309. A sealing gasket 305 is rotatably installed on the piston 303 and the suction pipe 302, and the sealing gasket 305 is supported by the support spring 306. When the suction handle 308 is pulled upward, the lower sealing gasket 305 will be opened under the action of suction, and the waste liquid will flow into the lower side of the piston 303. When the suction handle 308 is pushed downward, the upper sealing gasket 305 will be opened under the pushing action of the waste liquid, and the waste liquid will flow into the upper side of the piston 303 through the suction hole 304. When the suction handle 308 is pulled upward further, the sealing gasket 305 is in a closed state, and the waste liquid on the upper side of the piston 303 will flow out through the drain pipe 309.

[0026] Example 2

[0027] Combination Figure 1 , Figure 4 and Figure 5 The feed hopper 2 is provided with a liquid storage mechanism 4, which includes a sealing plate 401. Two hinges 402 are fixedly installed in parallel between the sealing plate 401 and the feed hopper 2. A lever 403 is fixedly installed on the upper part of the sealing plate 401. Two support seats 404 are fixedly installed in parallel on the inner wall of the waste liquid bottle 1. A buffer spring 405 is fixedly installed between the two support seats 404 and the sealing plate 401.

[0028] See Figure 4 and Figure 5 Furthermore, based on Embodiment 1, sealing rings are fitted on both the upper and lower sides of the sealing plate 401, the lever 403 is installed obliquely on the sealing plate 401, the two hinges 402 are located at the lower part of the sealing plate 401, and the two buffer springs 405 are installed obliquely on the lower side of the sealing plate 401.

[0029] Specifically, the sealing plate 401 is rotatably connected to the feed hopper 2 by using the hinge 402, and the support plate 404 and the buffer spring 405 are installed between the sealing plate 401 and the waste liquid bottle 1, so that the sealing plate 401 is tightly attached to the inner wall of the feed hopper 2 without the action of external force. When the lever 403 is turned, the thrust counteracts the supporting force of the buffer spring 405, causing the sealing plate 401 to rotate around the hinge 402. At this time, the waste liquid can be put into the waste liquid bottle 1 through the gap between the waste liquid plate 401 and the feed hopper 2. When the lever 403 is released, the sealing plate 401 can be restored under the action of the buffer spring 405. The sealing rings installed on both the upper and lower sides of the sealing plate 401 can ensure the sealing of the waste liquid bottle 1.

[0030] In actual operation, the piston 303 moves up and down along the inner wall of the waste liquid bottle 1 by pushing and pulling the liquid-drawing handle 308. When the piston 303 moves back and forth, the waste liquid in the waste liquid bottle 1 can be drawn out and discharged through the drain pipe 309. A sealing gasket 305 is rotatably installed on the piston 303 and the liquid-drawing pipe 302, and the sealing gasket 305 is supported by the support spring 306. When the liquid-drawing handle 308 is pulled upward, the lower sealing gasket 305 will be opened under the action of suction, and the waste liquid will flow into the lower side of the piston 303. When the liquid-drawing handle 308 is pushed downward, the upper sealing gasket 305 will be opened under the pushing action of the waste liquid, and the waste liquid will flow into the upper side of the piston 303 through the liquid-drawing hole 304. When the liquid-drawing handle 308 is pulled upward further, the sealing gasket 305 is in the closed state, and the waste liquid on the upper side of the piston 303 will flow out through the drain pipe 309.

[0031] By using hinge 402 to rotatably connect sealing plate 401 to feed hopper 2, and installing support plate 404 and buffer spring 405 between sealing plate 401 and waste liquid bottle 1, sealing plate 401 is tightly attached to the inner wall of feed hopper 2 without external force. When lever 403 is turned, the thrust counteracts the supporting force of buffer spring 405, causing sealing plate 401 to rotate around hinge 402. At this time, waste liquid can be poured into waste liquid bottle 1 through the gap between waste liquid plate 401 and feed hopper 2. When lever 403 is released, sealing plate 401 can be restored under the action of buffer spring 405. The sealing rings installed on both the upper and lower sides of sealing plate 401 ensure the sealing of waste liquid bottle 1.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
