AI Technical Summary
The overflow hole of the laboratory sink emits an odor due to long-term disuse, and researchers often forget to use and store the plug, causing the sink to overflow.
Design a laboratory water tank structure including a drainage pipe, a baffle, and a drainage cover. The baffle closes the drainage pipe when the water level is below the overflow hole to prevent odor from escaping. The drainage automatically opens when the water level rises. The sealing strip is used to improve the airtightness.
It effectively isolates the odor from the overflow hole, avoids the inconvenience of traditional plug management, and achieves a convenient odor-proof effect.

TECHNICAL FIELD
[0001] The utility model relates to the technical field of sink, especially to a sink structure of laboratory. BACKGROUND
[0002] In order to prevent overflow, the existing laboratory sink is provided with overflow hole, because the laboratory sink often discharges chemical substances, and the use rate of overflow hole is far less than that of the drain hole at the bottom of the sink, which leads to that the pipeline connected with the overflow hole cannot be effectively flushed, and the overflow hole emits odor. In order to solve the problem of odor emission of overflow hole, the conventional method is to add a plug in the overflow hole, and the plug is opened when the overflow hole is needed, which can effectively solve the problem of odor emission of overflow hole, but the experimenter often forgets to put the plug after using the overflow hole, resulting in loss of the plug, or forgets to take out the plug when the overflow hole is needed, resulting in overflow of the sink.

[0005] A sink structure of laboratory, comprising a sink body, a drain pipeline, a baffle and a drain cover, a water leakage hole is formed in the bottom of the sink body, a plurality of overflow holes are formed in the upper part of the side wall of the sink body, one end of the drain pipeline is fixedly connected with the outer side wall of the sink body, the plurality of overflow holes are arranged in the drain pipeline, two connecting ears are arranged on the outer wall of the sink body above the drain pipeline, the baffle is hingedly connected in the two connecting ears through a horizontal shaft, the baffle abuts against one end of the drain pipeline away from the sink body and covers the end, the drain cover is fixedly connected with the outer wall of the sink body, the drain cover covers the drain pipeline and the baffle, and a water leakage pipe is connected with the bottom of the drain cover.
[0006] Further, mounting holes are arranged on the side wall of the sink body at positions between the plurality of overflow holes, a sleeve is fixedly connected with the inner wall of the drain cover at a position corresponding to the mounting hole, the sleeve is threaded, a bolt is transversely arranged in the mounting hole, the bolt is screwedly connected in the sleeve, a longitudinal slot hole is formed in the baffle at a position corresponding to the bolt, the bolt passes through the slot hole, a boss is arranged on the outer wall of the sink body at a position corresponding to the slot hole, and the size of the boss is larger than that of the slot hole.
[0007] Further, a sealing rubber strip is connected with the open end of the drain cover, and the sealing rubber strip abuts against the outer wall of the sink body.
[0008] The utility model discloses beneficial effect is: through setting up drain pipeline and baffle outside the water tank body, when water level line does not rise to overflow hole, baffle can stop drain pipeline, thereby insulating the stench of waste water pipe, avoid the overflow hole and stink, when water level line overflows overflow hole, then can open baffle, and the water is drained successfully, compared with the traditional plug anti-odor mode is more convenient.

DETAILED DESCRIPTION
[0014] The technical scheme in the utility model embodiments will be described clearly and completely below in conjunction with the drawings in the utility model embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art belong to the protection scope of the utility model.
[0015] As Figures 1-4 The utility model discloses a laboratory's water tank structure, including water tank body 1, drain pipeline 11, baffle 2 and drain cover 3, water tank body 1 is rectangular, the bottom of water tank body 1 is set up with leakage hole 12, the upper portion of the front side wall of water tank body 1 is set up with four overflow holes 13, one end of drain pipeline 11 is welded on the outer wall of water tank body 1, four overflow holes 13 are set up in drain pipeline 11, two connecting lug 14 are set up on the outer wall of water tank body 1 above drain pipeline 11, baffle 2 is hinged in two connecting lug 14 through a horizontal shaft 4, baffle 2 leans on the end of drain pipeline 11 away from water tank body 1 and covers this end, drain cover 3 is fixedly connected on the outer wall of water tank body 1, drain cover 3 covers drain pipeline 11 and baffle 2, the bottom of drain cover 3 is connected with leakage pipe 31, and leakage pipe 31 is used for connecting with waste water pipe.
[0016] In actual use, by arranging the drain pipe 11 and the baffle 2 outside the sink body 1, when the water level does not rise to the overflow hole 13, the baffle 2 can block the drain pipe 11, thereby isolating the odor of the waste water pipe and avoiding the odor of the overflow hole 13; when the water level rises to the overflow hole 13, the baffle 2 can be pushed away, and the water can be smoothly drained, which is more convenient than the traditional way of preventing odor by adding a plug.
[0017] In the embodiment, the sink body 1 is provided with mounting holes 15 at positions between the four overflow holes 13 on the side wall, the inner wall of the drain cover 3 is fixedly connected with a sleeve 32 at positions corresponding to the mounting holes 15, the sleeve 32 is threaded, the sink body 1 is provided with bolts 5 along the transverse direction in the mounting holes 15, the bolts 5 are threadedly connected in the sleeve 32, thereby locking the drain cover 3 outside the sink body 1, the baffle 2 is provided with a longitudinal slot 21 at a position corresponding to the bolt 5, the bolt 5 passes through the slot 21, so that the baffle 2 can be flexibly rotated, the outer wall of the sink body 1 is provided with a boss 16 at a position corresponding to the slot 21, the boss 16 is larger than the slot 21 in size, and the boss 16 can block the slot 21 to avoid the odor overflowing from the slot 21.
